The present disclosure relates to a method and an apparatus for generating aerosols. More particularly, the present disclosure relates to a method and an apparatus for generating aerosol by heating an aerosol generating material in a cigarette.
Recently, there is a growing demand for alternative methods for resolving problems of a common cigarette. For example, there is a growing demand for a method of generating aerosol by heating an aerosol generating material in a cigarette instead of burning the cigarette to generate aerosol. Therefore, researches on heating-type cigarettes or heating-type aerosol generating apparatuses are being actively carried out.
Provided are a method and an apparatus for generating aerosols. Also, provided is a computer-readable recording medium having recorded thereon a program for executing the above method on a computer. Technical problems to be solved are not limited to the technical problems as described above, and other technical problems may exist.
According to an aspect of the present disclosure,
an aerosol generating system includes a holder configured to generate aerosol by heating a cigarette; and a cradle including an inner space into which the holder is inserted, wherein the holder is inserted into the inner space of the cradle and then tilted to generate the aerosol.
A holder may generate aerosol by heating a cigarette. Also, aerosol may be generated independently by the holder or even when the holder is inserted into a cradle and is tilted. Particularly, when the holder is tilted, a heater may be heated by power of a battery of the cradle.
Also, the heater has a smooth surface for smooth insertion of a cigarette, and the heater is not damaged by frictional force during insertion of a cigarette.
Also, the operation of the holder may be continuously monitored in any state including a state in which the holder is coupled with the cradle and tilted or a state in which the holder is separated from the cradle.
Also, a cooling structure included in a cigarette may cool aerosol passing through the cooling structure. Particularly, uniform channels are distributed in the cooling structure, and thus aerosol may flow smoothly and the aerosol cooling effect may be improved.
The cooling structure also has the effect of filtering certain materials included in aerosol. Also, since the cooling structure may be made of pure polylactic acid, specific materials may be prevented from being generated as aerosol passes through the cooling structure.
Also, as a vortex is formed while aerosol is passing through the cooling structure, the aerosol cooling effect and specific material filtering effect are improved.
Also, an aerosol generating apparatus in which a holder and a cradle are combined (integrated) may be provided. According to the aerosol generating apparatus, a user may mount a cigarette in the aerosol generating apparatus by pushing the cigarette along the accommodating path of an accommodating portion. Also, after the use of the cigarette is completed, the user may easily separate the cigarette from the aerosol generating apparatus by a simple action for separating the cigarette from the accommodating portion of a casing.
Also, since the accommodating portion may be separated from the casing, a tobacco material which is generated during smoking and attached to the periphery of the cigarette may be easily discharged out of the casing together with the accommodating portion.
Also, when the accommodating portion is separated from the casing, a protruding tube and a heater are exposed to the outside, and thus the user may directly check the states thereof and easily perform a cleaning operation.
In addition, while a cigarette is being inserted into the accommodating portion of the aerosol generating apparatus, a protruding portion protruding from the accommodating path or a cigarette supporting protrusion of the cover comes into contact with the cigarette, and thus the cigarette is stably supported. Therefore, the state that a cigarette is accommodated in the aerosol generating apparatus is stably maintained while the aerosol generating apparatus is being used, and thus a user may safely enjoy the aerosol generating apparatus
Also, as the protruding portion contacts a portion of the outer surface of a cigarette, a flow path in which the air may pass is formed between the accommodating path and the cigarette, and thus the outside air to assist generation of aerosol may be supplied smoothly and sufficiently into the aerosol generating apparatus.
Also, by reducing a contact area between a cigarette and the accommodating path, a heat conduction area through which heat is transmitted from the cigarette to the casing may be reduced.
Also, since a cigarette and the accommodating path are apart from each other, even when the heater is inserted into the cigarette and the cigarette expands, the cigarette is easily inserted into the accommodating path of the accommodating portion. When there is no space between a cigarette and the accommodating portion, the outer wall of the cigarette expands while the heater is being inserted into the cigarette and the frictional force between the cigarette and the accommodating portion increases, and thus it becomes difficult to insert the cigarette into the accommodating portion.
Also, the accommodating portion may be cooled by introducing the outside air stream into the space formed between the outer surface of the cigarette and the accommodating path.
Also, the air introduced into the cigarette may be preheated by the configuration of the aerosol generating apparatus with the accommodating path and the protruding portion.
Also, since a mechanism for moving the accommodating portion with regard to the aerosol generating apparatus when the accommodating portion is not separated from the aerosol generating apparatus is not used, the number of components is reduced, thereby simplifying the overall configuration of the aerosol generating apparatus and preventing frequent troubles related to a movable accommodating portion.
According to an aspect of the present disclosure, there is provided an aerosol generating system including a holder configured to generate aerosol by heating a cigarette; and a cradle including an inner space into which the holder is inserted, wherein the holder is inserted into the inner space of the cradle and then tilted to generate the aerosol.

In the above-described aerosol generating system, the holder accumulates a smoking pattern monitored in the second state to a smoking pattern monitored in the first state when smoking is performed in the first state and subsequently performed in the second state later, and the holder controls the heater provided in the holder to stop heating the inserted cigarette when the accumulated smoking pattern satisfies the smoking restriction condition.

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.
Referring to
Only components associated with the present embodiment are shown in the holder 1 shown in
When a cigarette is inserted into the holder 1, the holder 1 heats the heater 130. The temperature of an aerosol generating material in the cigarette is raised by the heated heater 130, and thus aerosol is generated. The generated aerosol is delivered to a user through a cigarette filter. However, even when a cigarette is not inserted into the holder 1, the holder 1 may heat the heater 130.
The casing 140 may be detached from the holder 1. For example, when a user rotates the casing 140 clockwise or counterclockwise, the casing 140 may be detached from the holder 1.
The diameter of a hole formed by a terminal end 141 of the casing 140 may be smaller than the diameter of a space formed by the casing 140 and the heater 130. In this case, the hole may serve as a guide for a cigarette inserted into the holder 1.
The battery 110 supplies power used for the holder 1 to operate. For example, the battery 110 may supply power for heating the heater 130 and supply power for operating the control unit 120. In addition, the battery 110 may supply power for operating a display, a sensor, a motor, and the like installed in the holder 1.
The battery 110 may be a lithium iron phosphate (LiFePO4) battery, but is not limited to the example described above. For example, the battery 110 may be a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, etc.
Also, the battery 110 may have a cylindrical shape having a diameter of 10 mm and a length of 37 mm, but is not limited thereto. The capacity of the battery 110 may be 120 mAh or more, and the battery 110 may be a rechargeable battery or a disposable battery. For example, when the battery 110 is rechargeable, the charging rate (C-rate) of the battery 110 may be 10 C and the discharging rate (C-rate) may be 16 C to 20 C. However, the present disclosure is not limited thereto. Also, for stable use, the battery 110 may be manufactured, such that 80% or more of the total capacity may be ensured even when charging/discharging are performed 8000 times.
Here, it may be determined whether the battery 110 is fully charged or completely discharged based on a level of power stored in the battery 110 as compared to the entire capacity of the battery 110. For example, when power stored in the battery 110 is equal to or more than 95% of the total capacity, it may be determined that the battery 110 is fully charged. Furthermore, when power stored in the battery 110 is 10% or less of the total capacity, it may be determined that the battery 110 is completely discharged. However, the criteria for determining whether the battery 110 is fully charged or completely discharged are not limited to the above examples.
The heater 130 is heated by power supplied from the battery 110. When a cigarette is inserted into the holder 1, the heater 130 is located inside the cigarette. Therefore, the heated heater 130 may raise the temperature of an aerosol generating material in the cigarette.
The shape of the heater 130 may be a combination of a cylindrical shape and a conical shape. The diameter of the heater 130 may be appropriately selected within the range from 2 mm to 3 mm. Preferably, the heater 130 may be fabricated to have a diameter of 2.15 mm, but is not limited thereto. In addition, the heater 130 may have a suitable length within the range from 20 mm to 30 mm. Preferably, the heater 130 may be fabricated to have a length of 19 mm, but is not limited thereto. Also, a terminal end 131 of the heater 130 may be formed to have an acute angle, but is not limited thereto. In other words, the heater 130 may have any shape as long as the heater 130 may be inserted into the cigarette. In addition, only a portion of the heater 130 may be heated. For example, assuming that the length of the heater 130 is 19 mm, only 12 mm from the terminal end 131 of the heater 130 may be heated, and the remaining portion of the heater 130 may not be heated.
The heater 130 may be an electro-resistive heater. For example, the heater 130 includes an electrically conductive track, and the heater 130 may be heated as a current flows through the electrically conductive track.
For stable use, the heater 130 may be supplied with power according to the specifications of 3.2 V, 2.4 A, and 8 W, but is not limited thereto. For example, when power is supplied to the heater 130, the surface temperature of the heater 130 may rise to 400° C. or higher. The surface temperature of the heater 130 may rise to about 350° C. before 15 seconds after the power supply to the heater 130 starts.
Hereinafter, the structure of the heater 130 will be described in detail with reference to

According to an embodiment, the heating unit 1315 may have a needle-like shape (e.g., a combination of a cylindrical shape and a conical shape). In addition, the heating unit 1315 may include a base portion and a tip portion. For example, the base portion of the heating unit 1315 may be formed to have a cylindrical shape, but is not limited thereto. Also, the tip portion of the heating unit 1315 may be formed at one end of the base portion to facilitate insertion into an aerosol forming material. At this time, the base portion and the tip portion may be formed as a single body. Alternatively, the base portion and the tip portion may be separately fabricated and then adhered to each other.
The heating unit 1315 may include a thermally conductive material. For example, the thermally conductive material may include ceramic including alumina or zirconia, an anodized metal, a coated metal, polyimide (PI), etc., but is not limited thereto.
According to an embodiment, the first sheet 1325 may surround at least a portion of the heating unit 1315. For example, the first sheet 1325 may surround at least a portion of the outer circumferential surface of the base portion of the heater 130. Electrically conductive tracks may be formed on both sides of first sheet 1325.
Also, a first electrically conductive track formed on one of both sides of the first sheet 1325 may receive power from a battery. As a current flows through the first electrically conductive track, the temperature of the first electrically conductive track may rise. Also, as the temperature of the first electrically conductive track rises, heat is transferred to the heating unit 1315 adjacent to the first electrically conductive track, and thus the heating unit 1315 may be heated.
Depending on power consumption of a resistor of the first electrically conductive track, the heating temperature for the first electrically conductive track may be determined. Also, based on power consumption of the resistor of the first electrically conductive track, the resistance value of the first electrically conductive track may be set.
For example, the resistance value of the first electrically conductive track may be between 0.5 ohms and 1.2 ohms at a room temperature of 25° C., but is not limited thereto. At this time, the resistance value of the first electrically conductive track may be set based on the material, the length, the width, the thickness, and the pattern of the first electrically conductive track.
The internal resistance of the first electrically conductive track may increase as the temperature thereof rises, due to the resistive temperature coefficient characteristics. For example, the temperature of the first electrically conductive track may be proportional to the magnitude of the resistance of the first electrically conductive track in a predetermined temperature section.
For example, a predetermined voltage may be applied to the first electrically conductive track, and a current flowing through the first electrically conductive track may be measured by a current sensor. In addition, the resistance of the first electrically conductive track may be calculated based on a ratio between the measured current to the applied voltage. Based on the calculated resistance, the temperature of the first electrically conductive track or the heating unit 1315 may be estimated, according to the resistance temperature coefficient characteristic of the first electrically conductive track.
For example, the first electrically conductive track may include tungsten, gold, platinum, silver copper, nickel palladium, or a combination thereof. Also, the first electrically conductive track may be doped with a suitable dopant and may include an alloy.
One or both surfaces of the first sheet 1325 may include a second electrically conductive track, which has a resistance temperature coefficient characteristic and is used to detect the temperature of the heating unit 1315. The internal resistance of the second electrically conductive track may increase as the temperature rises, according to the resistive temperature coefficient characteristics. For example, the temperature of the second electrically conductive track may be proportional to the magnitude of the resistance of the second electrically conductive track in a predetermined temperature section.
The second electrically conductive track may be disposed adjacent to the heating unit 1315. Accordingly, when the temperature of the heating unit 1315 rises, the temperature of the second electrically conductive track adjacent thereto may also rise. A predetermined voltage may be applied to the second electrically conductive track, and a current flowing through the second electrically conductive track may be measured through a current detector. In addition, the resistance of the second electrically conductive track may be determined based on a ratio between the measured current to the applied voltage. Based on the determined resistance, the temperature of the heating unit 1315 may be determined, according to the resistance temperature coefficient characteristic of the second electrically conductive track.
Depending on the temperature of the second electrically conductive track, the resistance value of the second electrically conductive track may change. Therefore, based on the change of the resistance value of the second electrically conductive track, the temperature change of the second electrically conductive track may be measured. For example, the resistance value of the second electrically conductive track may be between 7 ohms and 18 ohms at a room temperature of 25° C., but is not limited thereto. At this time, the resistance value of the second electrically conductive track may be set based on the material, the length, the width, the thickness, and the pattern of the second electrically conductive track.
For example, the second electrically conductive track may include tungsten, gold, platinum, silver copper, nickel palladium, or a combination thereof. Also, the second electrically conductive track may be doped with a suitable dopant or may include an alloy.
The first electrically conductive track may be connected to a battery through an electrical connecting portion. As described above, as power is supplied from the battery, the temperature of the first electrically conductive track may rise.
The second electrically conductive track may include an electrical connecting portion to which a DC voltage is applied. The electrical connecting portion of the second electrically conductive track is separated from the electrical connecting portion of the first electrically conductive track. Also, when a DC voltage applied to the second electrically conductive track is constant, the magnitude of a current flowing through the second electrically conductive track may be determined based on the resistance of the second electrically conductive track.
The second electrically conductive track may be connected to an operating amplifier (OP Amp). The OP Amp includes a power supply unit that receives DC power from the outside, an input unit that is electrically connected to the second electrically conductive track and receives a DC voltage and/or a current, and an output unit that outputs a signal based on the DC voltage and/or the current applied to the input unit.
The OP Amp may receive a DC voltage through the power supply unit. Also, the OP Amp may receive a DC voltage through the input unit. At this time, the magnitude of the DC voltage applied through the input unit of the OP Amp and the magnitude of the DC voltage applied through the power supply unit of the OP Amp may be the same. Also, the DC voltage applied to the input unit of the OP Amp may be equal to the DC voltage applied to the electrically connecting portion of the second electrically conductive track.
The electrical connecting portion of the second electrically conductive track and the input unit of the OP Amp may be separated from the electrical connecting portion of the first electrically conductive track.
As the temperature of the second electrically conductive track changes, the resistance value of the second electrically conductive track may change. Thus, the second electrically conductive track functions as a variable resistor that is controlled by the temperature as a control variable and, as the resistance value of the second electrically conductive track changes, a current flowing into the input unit of the OP Amp electrically connected to the second electrically conductive track changes. As the resistance of the second electrically conductive track increases, a current flowing into the input unit of the OP Amp electrically connected to the second electrically conductive track is reduced. At this time, even when the resistance value of the second electrically conductive track is changed, the DC voltage applied to the input unit of the OP Amp may be constant.
As the current flowing into the input unit of the OP Amp changes, a voltage and/or a current of a signal output from the output unit of the OP Amp may change. For example, as an input current of the OP Amp increases, an output voltage of the OP Amp may increase. In another example, as the input current of the OP Amp increases, the output voltage of the OP Amp may decrease.
A relationship between the temperature and the resistance value of the second electrically conductive track, a relationship between the resistance value of the second electrically conductive track and the input current applied to the OP Amp, and a relationship between the input current and the output voltage of the OP Amp when a constant DC voltage is applied to the input unit of the OP Amp may be experimentally obtained or set. Therefore, the output voltage and/or a change of the output voltage of the OP Amp may be measured to detect a change in temperature and/or a change of temperature of the second electrically conductive track.
For example, the OP Amp may have a characteristic that the voltage of the output unit of the OP Amp increases as the input current flowing into the input unit increases. In this case, the temperature of a heater rises as power is supplied to the first electroconductive track. As a result, the temperature of the second electrically conductive track rises. At this time, since the resistance value of the second electrically conductive track increases, the magnitude of the input current applied to the input unit of the OP Amp may be reduced. Therefore, the voltage at the output unit of the OP Amp decreases. On the contrary, the voltage at the output unit of the OP Amp increases as power supply to the first electrically conductive track is interrupted or power supplied to the first electrically conductive track decreases and the temperature of a heater decreases.
In another example, the OP Amp may have a characteristic that the voltage of the output unit of the OP Amp decreases as the input current flowing into the input unit increases. In this case, the temperature of a heater rises as power is supplied to the first electroconductive track. As a result, the temperature of the second electrically conductive track rises. At this time, since the resistance value of the second electrically conductive track increases, the magnitude of the input current applied to the input unit of the OP Amp may be reduced. Therefore, the voltage at the output unit of the OP Amp increases. On the contrary, the voltage at the output unit of the OP Amp decreases as power supply to the first electrically conductive track is interrupted or power supplied to the first electrically conductive track decreases and the temperature of a heater decreases.
The output unit of the OP Amp may be connected to a processor. For example, the processor may be an micro controller unit (MCU). The processor may detect the temperature of the second electrically conductive track or a heating unit based on the output voltage of the OP Amp. The processor may also adjust a supply voltage supplied to the first electrically conductive track based on the temperature of the heating unit.
According to an embodiment, the first electrically conductive track and the second electrically conductive track may be formed on both sides of the first sheet 1325, respectively. For example, the first electrically conductive track may be included on one side of the first sheet 1325 in contact with the heating unit 1315, and the second electrically conductive track may be included on the other side. In another example, the second electrically conductive track may be included on one side of the first sheet 1325 in contact with the heating unit 1315, and the first electrically conductive track may be included on the other side.
According to another embodiment, the first electrically conductive track and the second electrically conductive track may be included on the same side of the both sides of the first sheet 1325. For example, both the first electrically conductive track and the second electrically conductive track may be included on one of the both side of the first sheet 1325 in contact with the heating unit 1315. In another example, both the first electrically conductive track and the second electrically conductive track may be included on one of the both side of the first sheet 1325 not in contact with the heating unit 1315.
For example, the first sheet 1325 may be a green sheet including a ceramic composite material. Here, the ceramic may include, but not limited to, compounds like alumina and zirconia.
According to an embodiment, the second sheet 1335 may surround at least a portion of the first sheet 1325. Also, the second sheet 1335 may have rigidity.
Therefore, the second sheet 1335 protects the first sheet 1325 and electrically conductive tracks when the heater 130 is inserted into an aerosol-forming material.
For example, the second sheet 1335 may be a green sheet including a ceramic composite material. Here, the ceramic may include, but not limited to, compounds like alumina and zirconia.
Each of the heating unit 1315, the first sheet 1325, and the second sheet 1335 may selectively include a material in the same material group, e.g., ceramics that are compounds like alumina and zirconia.
Also, each of the first electrically conductive track and the second electrically conductive track may selectively include a material in the same material group, e.g., tungsten, gold, platinum, silver copper, nickel palladium, or a combination thereof. Here, even when the first electrically conductive track and the second electrically conductive track include the same material, the resistance values of the first electrically conductive track and the second electrically conductive track may be different from each other due to differences in lengths, widths, or patterns of the first electrically conductive track and the second electrically conductive track.
According to an embodiment, the first electrically conductive track for heating the heating unit 1315 may be included in the heating unit 1315, the first sheet 1325, or the second sheet 1335. Alternatively, a plurality of electrically conductive tracks (e.g., first electrically conductive tracks) for heating the heating unit 1315 may be included in at least one of the heating unit 1315, the first sheet 1325, and the second sheet 1335.
According to an embodiment, the second electrically conductive track for detecting the temperature of the heating unit 1315 may be included in the heating unit 1315, the first sheet 1325, or the second sheet 1335. Alternatively, a plurality of electrically conductive tracks (e.g., second electrically conductive tracks) for detecting the temperature of the heating unit 1315 may be included in at least one of the heating unit 1315, the first sheet 1325, and the second sheet 1335.
According to an embodiment, the first electrically conductive track for heating the heating unit 1315 and the second electrically conductive track for detecting the temperature of the heating unit 1315 may be included in the same component from among the heating unit 1315, the first sheet 1325, and the second sheet 1335. Alternatively, the first electrically conductive track for heating the heating unit 1315 and the second electrically conductive track for detecting the temperature of the heating unit 1315 may be included in different components from among the heating unit 1315, the first sheet 1325, and the second sheet 1335, respectively.
As the heater 130 is provided with a coating layer 1345, a stepped surface formed by a stacked structure including the heating unit 1315, the first sheet 1325, and the second sheet 1335 may be planarized. For example, a stepped surface 1355 may be formed because the edge portion of the first sheet 1325 and the edge portion of the second sheet 1335 do not form a continuous surface or due to the thicknesses of the first sheet 1325 and the second sheet 1335. For example, due to the stepped surface 1355, friction may increase when the heater 130 is inserted into an aerosol forming material. In addition, deposition of a deposition material or residues from the aerosol-forming material on the stepped surface 1355 contaminates the heater 130, thereby deteriorating the performance (e.g., the thermal conductivity) of the heater 130. Therefore, the coating layer 1345 may be formed on the outer surface of the heater 130 to planarize the stepped surface 1355.
The outer surface of the heater 130, which is formed by the coating layer 1345, may include a tip portion of the coating layer 1345 corresponding to a tip portion of the heating unit 1315, a base portion of heating unit 1315, and a base portion of the coating layer 1345 corresponding to the first sheet 1325 and the second sheet 1335. At this time, a portion of the coating layer 1345 extending from the tip portion of the coating layer 1345 to the base portion of the coating layer 1345 may have a smooth outer surface without the stepped surface 1355 or a concavo-convex portion.
The coating layer 1345 may include a heat resistant composition. For example, the coating layer 1345 may include, but is not limited to, a single coating layer of a glass coating layer, a Teflon coating layer, and a molar coating layer. Also, the coating layer 1345 may include, but is not limited to, a composite coating layer composed of a combination of two or more of a glass coating layer, a Teflon coating layer, and a molar coating layer.
Referring to
For example, a terrace 1321 may be formed by the thickness of the first sheet 1325. Furthermore, the terrace 1331 may be formed by the thickness of the second sheet 1335.
Furthermore, a step 1311 may be formed because the boundary between the tip portion and the base portion of a heating unit does not coincide with the edge portion of the first sheet 1325. Furthermore, since the edge portion of the first sheet 1325 does not coincide with the edge portion of the second sheet 1335, a step 1322 may be formed.
At this time, deposition or debris of an aerosol forming material may be piled in the space formed by the stepped surface 1355, and thus the heater may be contaminated. As described above with reference to
A first surface 1351 of the first sheet 225 may include a first electrically conductive track 1352 and a second surface 1353 may include a second electrically conductive track 1354.
The first electrically conductive track 1352 may heat the heating unit 1315 of the heater 130 as a current flows therein. An electrically conductive track may be connected to an external power source via a connection. Also, as power is supplied to the electrically conductive track from an external power source, a current may flow in the electrically conductive track. Therefore, the electrically conductive track may generate heat and transfer the heat to a nearby heating unit 1315, thereby heating the heating unit 1315.
For example, the first electrically conductive track 1352 of the first surface 1351 may be formed in various patterns, such as a curved shape and a mesh shape.
A second surface 1353 of the first sheet 1325 may include a second electrically conductive track 1354, which has a resistance temperature coefficient characteristic and is used to detect the temperature of the heating unit 1315. As described above, the internal resistance of the second electrically conductive track 1354 may increase as the temperature rises, according to the resistance temperature coefficient characteristic. For example, the temperature of the second electrically conductive track 1354 may be proportional to the magnitude of the resistance of the second electrically conductive track 1354 in a predetermined temperature section.
The second electrically conductive track 1354 may be disposed adjacent to the heating unit 1315. For example, heat may be transferred from the heating unit 1315 to the second electrically conductive track 1354 as the heating unit 1315 is heated. When the temperature of the heating unit 1315 rises, the temperature of the second electrically conductive track 1354 also rises, and the resistance of the second electrically conductive track 1354 may increase. On the contrary, when the temperature of the heating unit 1315 decreases, as the temperature of the second electrically conductive track 1354 also decreases, the resistance of the second electrically conductive track 1354 may decrease.
The second electrically conductive track 1354 may be connected to the control unit through a connection. For example, the second electrically conductive track 1354 may be connected to a processor that controls the temperature of the heating unit 1315. For example, the second electrically conductive track 1354 may be connected to the control unit. By using the relationship between the resistance and the temperature of the second electrically conductive track 1354, the resistance of the second electrically conductive track 1354 is determined from a voltage and a current of the second electrically conductive track 1354, and the temperature of the heating unit 1315 may be determined based on the determined resistance. Based on the temperature determined by using the second electrically conductive track 1354, power supplied to the first electrically conductive track 1352 may be adjusted.
The second electrically conductive track 1354 may be disposed adjacent to the heating unit 1315 to receive the heat from the heating unit 1315. Also, the first electrically conductive track 1352 of the second surface 1353 may be formed in various patterns, such as a curved shape and a mesh shape.
The first surface 1351 including the first electrically conductive track 1352 may be one of surfaces of the first sheet 1325 that contacts the heating unit 1315 and the second surface including the second electro—1353 may not be the other one of the surfaces of the first sheet 1325 that does not contact the heating unit 1315. On the contrary, the second surface 1353 including the second electrically conductive track 1354 may be one surface that contacts the heating unit 1315, and the first surface 1351 including the first electrically conductive track 1352 may be the other surface that does not contact the heating unit 1315.

The battery 110 may be connected to the heater 130 via a first connector 1361. For example, the battery 110 may be electrically connected to a first electrically conductive track of a first sheet of the heater 130 and supply power to the first electrically conductive track.
The battery 110 may include a power source and a circuit for supplying power. For example, the battery 110 may provide a supply voltage to the first electrically conductive track via the first connector 1361. The supply voltage may be a DC or AC voltage, a pulse voltage having a constant period, or a pulse voltage having a fluctuating period, but is not limited thereto.
The control unit 120 may include a processor. For example, the processor may be, but is not limited to, an MCU.
The control unit 120 may be connected to the heater 130 via a second connector 1362. For example, the control unit 120 may be electrically connected to the second electrically conductive track of the first sheet of the heater 130 and determine the temperature of the heater 130. The control unit 120 may also adjust the temperature of the heater 130 based on the determined temperature of the heater 130. For example, the control unit 120 may determine whether to adjust the temperature of the heater 130 based on the determined temperature of the heater 130. The control unit 120 may adjust power supplied from the battery 110 to the heater 130 based on the determination of whether to adjust the temperature of the heater 130. For example, the control unit 120 may adjust the magnitude or the period of a pulse voltage supplied from the battery 110 to the heater 130.
The control unit 120 according to an embodiment may include an OP Amp.
The second electrically conductive track may be connected to the OP Amp via the second connector 1362. The OP Amp includes a power supply unit that receives DC power from the outside, an input unit that is electrically connected to the second electrically conductive track and receives a DC voltage and/or a current, and an output unit that outputs an electric signal based on the DC voltage and/or the current applied to the input unit.
The OP Amp may receive a DC voltage through the power supply unit. Also, the OP Amp may receive a DC voltage through the input unit. At this time, the magnitude of the DC voltage applied through the input unit of the OP Amp and the magnitude of the DC voltage applied through the power supply unit of the OP Amp may be the same. Also, the DC voltage applied to the input unit of the OP Amp may be equal to the DC voltage applied to the sefcond connector 1362 of the second electrically conductive track.
The second connector 1362 of the second electrically conductive track and the input unit of the OP Amp may be separated from the first connector 1361 of the first electrically conductive track.
As the temperature of the second electrically conductive track changes, the resistance value of the second electrically conductive track may change. Thus, the second electrically conductive track functions as a variable resistor that is controlled by the temperature as a control variable and, as the resistance value of the second electrically conductive track changes, a current flowing into the input unit of the OP Amp electrically connected to the second electrically conductive track changes. As the resistance of the second electrically conductive track increases, a current flowing into the input unit of the OP Amp electrically connected to the second electrically conductive track is reduced. At this time, even when the resistance value of the second electrically conductive track is changed, the DC voltage applied to the input unit of the OP Amp may be constant.
As the current flowing into the input unit of the OP Amp changes, a voltage and/or a current of a signal output from the output unit of the OP Amp may change. For example, as an input current of the OP Amp increases, an output voltage of the OP Amp may increase. In another example, as the input current of the OP Amp increases, the output voltage of the OP Amp may decrease.
A relationship between the temperature and the resistance value of the second electrically conductive track, a relationship between the resistance value of the second electrically conductive track and the input current applied to the OP Amp, and a relationship between the input current and the output voltage of the OP Amp when a constant DC voltage is applied to the input unit of the OP Amp may be experimentally obtained or set. Therefore, the output voltage and/or a change of the output voltage of the OP Amp may be measured to detect a change in temperature and/or a change of temperature of the second electrically conductive track.
For example, the OP Amp may have a characteristic that the voltage of the output unit of the OP Amp increases as the input current flowing into the input unit increases. In this case, the temperature of a heater rises as power is supplied to the first electroconductive track. As a result, the temperature of the second electrically conductive track rises. At this time, since the resistance value of the second electrically conductive track increases, the magnitude of the input current applied to the input unit of the OP Amp may be reduced. Therefore, the voltage at the output unit of the OP Amp decreases. On the contrary, the voltage at the output unit of the OP Amp increases as power supply to the first electrically conductive track is interrupted or power supplied to the first electrically conductive track decreases and the temperature of a heater decreases.
In another example, the OP Amp may have a characteristic that the voltage of the output unit of the OP Amp decreases as the input current flowing into the input unit increases. In this case, the temperature of a heater rises as power is supplied to the first electroconductive track. As a result, the temperature of the second electrically conductive track rises. At this time, since the resistance value of the second electrically conductive track increases, the magnitude of the input current applied to the input unit of the OP Amp may be reduced. Therefore, the voltage at the output unit of the OP Amp increases. On the contrary, the voltage at the output unit of the OP Amp decreases as power supply to the first electrically conductive track is interrupted or power supplied to the first electrically conductive track decreases and the temperature of a heater decreases.
The output unit of the OP Amp may be connected to a processor. The processor may be, for example, an MCU. The processor may detect the temperature of the second electrically conductive track or a heating unit based on the output voltage of the OP Amp. The processor may also adjust a supply voltage supplied to the first electrically conductive track based on the temperature of the heating unit.
Referring back to
For example, when a voltage applied to the second electrically conductive track and a current flowing through the second electrically conductive track are measured, a resistance R may be determined. At this time, a temperature T of the second electrically conductive track may be determined by Equation 1 below.
R=R0{1+α(T−T0)}| [Equation 1]
In Equation 1, R denotes a current resistance value of the second electrically conductive track, R0 denotes a resistance value at a temperature T0 (e.g., 0° C.), and a denotes a resistance temperature coefficient of the second electrically conductive track. Since conductive materials (e.g., metals) have inherent resistance temperature coefficients, a may be determined in advance according to a conductive material constituting the second electrically conductive track. Therefore, when the resistance R of the second electrically conductive track is determined, the temperature T of the second electrically conductive track may be calculated according to Equation 1.
The heater 130 may include at least one electrically conductive track (a first electrically conductive track and a second electrically conductive track). For example, the heater 130 may include, but is not limited to, two first electrically conductive tracks and one or two second electrically conductive tracks.
An electrically conductive track include an electro-resistive material. For example, an electrically conductive track may include a metal. In another example, an electrically conductive track may include an electrically conductive ceramic material, a carbon, a metal alloy, or a composite of a ceramic material and a metal.
In addition, the holder 1 may include both an electrically conductive track, which serve as temperature sensing sensors, and a temperature sensing sensor.
The control unit 120 controls the overall operation of the holder 1. Specifically, the control unit 120 controls not only operations of the battery 110 and the heater 130, but also operations of other components included in the holder 1. The control unit 120 may also check the status of each of the components of the holder 1 and determine whether the holder 1 is in an operable state.
The control unit 120 includes at least one processor. A processor may be implemented as an array of a plurality of logic gates or may be implemented as a combination of a general purpose microprocessor and a memory in which a program executable in the microprocessor is stored. It will be understood by one of ordinary skill in the art that the present disclosure may be implemented in other forms of hardware.
For example, the control unit 120 may control the operation of the heater 130. The control unit 120 may control an amount of power supplied to the heater 130 and a time for supplying the power, such that the heater 130 may be heated to a predetermined temperature or maintained at a proper temperature. The control unit 120 may also check the status of the battery 110 (e.g., the remaining amount of the battery 110) and generate a notification signal as occasions demand.
Also, the control unit 120 may check the presence or absence of a user's puff, check the strength of the puff, and count the number of puffs. Also, the control unit 120 may continuously check the time during which the holder 1 is operating. The control unit 120 may also check whether a cradle 2 to be described below is coupled with the holder 1 and control the operation of the holder 1 based on whether the cradle 2 is coupled with or separated from and the holder 1.
Meanwhile, the holder 1 may further include general-purpose components other than the battery 110, the control unit 120, and the heater 130.
For example, the holder 1 may include a display capable of outputting visual information or a motor for outputting tactile information. For example, when a display is included in the holder 1, the control unit 120 may provide a user information about the state of the holder 1 (e.g., availability of the holder, etc.), information about the heater 130 (e.g., start of preheating, progress of preheating, completion of preheating, etc.), information about the battery 110 (e.g., remaining power of the battery 110, availability, etc.), information about resetting of the holder 1 (e.g., reset timing, reset progress, reset completion, etc.), information about cleaning of the holder 1 (e.g., cleaning timing, cleaning progress, cleaning completion, etc.), information about charging of the holder 1 (e.g., need of charging, charging progress, charging completed, etc.), information about puff (e.g., the number of puffs, notification of expected completion of puffs, etc.), or information about safety (e.g., time of use, etc.) via the display. In another example, when a motor is included in the holder 1, the control unit 120 may transmit the above-described information to a user by generating a vibration signal by using the motor.
The holder 1 may also include a terminal coupled with at least one input device (e.g., a button) and/or the cradle 2 through which a user may control the function of the holder 1. For example, a user may perform various functions by using the input device of the holder 1. By adjusting the number of times a user presses the input device (e.g., once, twice, etc.) or the time during which the input device is being pressed (e.g., 0.1 second, 0.2 second, etc.), a desired function from among a plurality of functions of the holder 1 may be executed. As a user manipulates the input device, the holder 1 may perform a function of preheating the heater 130, a function of regulating the temperature of the heater 130, a function of cleaning the space in which a cigarette is inserted, a function of checking whether the battery 110 is in an operable state, a function of displaying the remaining power (available power) of the battery 110, a function of resetting the holder 1, etc. However, the functions of the holder 1 are not limited to the examples described above.
For example, the holder 1 may clean the space in which a cigarette is inserted by controlling the heater 130 as follows. For example, the holder 1 may clean the space in which a cigarette is inserted by heating the heater 130 to a sufficiently high temperature. Here, the sufficiently high temperature refers to a temperature suitable for cleaning the space in which a cigarette is inserted. For example, the holder 1 may heat the heater 130 to the highest temperature in a temperature range in which an aerosol may be generated from an inserted cigarette and a temperature range for preheating the heater 130, but the present invention is not limited thereto.
In addition, the holder 1 may maintain the temperature of the heater 130 at a sufficiently high temperature for a predetermined period of time. Here, the predetermined period of time refers to a period of time sufficient for the space in which a cigarette is inserted to be cleaned. For example, the holder 1 may maintain the temperature of the heated heater 130 for a suitable period of time from 10 seconds to 10 minutes, but the present disclosure is not limited thereto. Preferably, the holder 1 may maintain the temperature of the heated heater 130 for a suitable period of time selected within the range from 20 seconds to 1 minute. More preferably, the holder 1 may maintain the temperature of the heated heater 130 for a suitable period of time selected within the range from 20 seconds to 1 minute 30 seconds.
As the holder 1 heats the heater 130 to a sufficiently high temperature and also maintains the temperature of the heated heater 130 for a predetermined period of time, a material deposited on a surface of the heater 130 and/or the space in which a cigarette is inserted is volatilized, and thus cleaning effect may be obtained.
The holder 1 may also include a puff detecting sensor, a temperature sensing sensor, and/or a cigarette insertion detecting sensor. For example, the puff detecting sensor may be implemented by a common pressure sensor. Alternatively, the holder 1 may detect puffs based on a resistance change of an electrically conductive track included in the heater 130 without a separate puff detecting sensor. Here, the electrically conductive track includes an electrically conductive track for generating heat and/or an electrically conductive track for sensing temperature. Alternatively, the holder 1 may further include a puff detecting sensor separately from detection of puffs using an electrically conductive track included in the heater 130.
The cigarette insertion detecting sensor may be implemented by a common capacitive sensor or a resistance sensor. Also, the holder 1 may be fabricated to have a structure in which the outside air may flow in/out even in the state where the cigarette is inserted.

Only components of the cradle 2 related to the present embodiment are shown in
The battery 210 provides power used to operate the cradle 2. In addition, the battery 210 may supply power for charging the battery 110 of the holder 1. For example, when the holder 1 is inserted into the cradle 2 and the terminal 170 of the holder 1 is coupled with the terminal 260 of the cradle 2, the battery 210 of the cradle 2 may supply power to the battery 110 of the holder 1.
Also, when the holder 1 is coupled with the cradle 2, the battery 210 may supply power used for the holder 1 to operate. For example, when the terminal 170 of the holder 1 is coupled with the terminal 260 of the cradle 2, the holder 1 may operate by using power supplied by the battery 210 of the cradle 2 regardless of whether the battery 110 of the holder 1 is discharged or not.
For example, the battery 210 may be a lithium ion battery, but is not limited thereto. The capacity of the battery 210 may be greater than the capacity of the battery 110. For example, the capacity of the battery 210 may be, but is not limited to, 3000 mAh or greater.
The control unit 220 generally controls the overall operation of the cradle 2. The control unit 220 may control the overall operation of all the configurations of the cradle 2. The control unit 220 may also determine whether the holder 1 is coupled with the cradle 2 and control the operation of the cradle 2 according to coupling or separation of the cradle 2 and the holder 1.
For example, when the holder 1 is coupled with the cradle 2, the control unit 220 may supply power of the battery 210 to the holder 1, thereby charging the battery 110 or heating the heater 130. Therefore, even when remaining power of the battery 110 is low, a user may continuously smoke by coupling the holder 1 with the cradle 2.
The control unit 220 includes at least one processor. A processor may be implemented as an array of a plurality of logic gates or may be implemented as a combination of a general purpose microprocessor and a memory in which a program executable in the microprocessor is stored. It will be understood by one of ordinary skill in the art that the present disclosure may be implemented in other forms of hardware.
Meanwhile, the cradle 2 may further include general-purpose components other than the battery 210 and the control unit 220. For example, cradle 2 may include a display capable of outputting visual information. For example, when the cradle 2 includes a display, the control unit 220 generates a signal to be displayed on the display, thereby informing a user information regarding the battery 210 (e.g., the remaining power of the battery 210, availability of the battery 210, etc.), information regarding resetting of the cradle 2 (e.g., reset timing, reset progress, reset completion, etc.), information regarding cleaning of the holder 1 (e.g., cleaning timing, cleaning necessity, cleaning progress, cleaning completion, etc.), information regarding charging of the cradle 2 (e.g., charging necessity, charging progress, charging completion, etc.).
The cradle 2 may also include at least one input device (e.g., a button) for a user to control the function of the cradle 2, a terminal 260 to be coupled with the holder 1, and/or an interface for charging the battery 210 (e.g., an USB port, etc.).
For example, a user may perform various functions by using the input device of the cradle 2. By controlling the number of times that a user presses the input device or a period of time for which the input device is pressed, a desired function from among the plurality of functions of the cradle 2 may be executed. As a user manipulates the input device, the cradle 2 may perform a function of preheating the heater 130, a function of regulating the temperature of the heater 130, a function of cleaning the space in which a cigarette is inserted, a function of checking whether the cradle 2 is in an operable state, a function of displaying the remaining power (available power) of the battery 210 of the cradle 2, a function of resetting the cradle 2, etc. However, the functions of the cradle 2 are not limited to the examples described above.
The holder 1 may be inserted into the inner space 230 of the cradle 2, as described above with reference to
Referring to
The cradle 2 may include at least one attaching member 271 and/or 272 to increase attachment strength with the holder 1. Also, at least one attaching member 181 may be included in the holder 1 as well. Here, attaching members 181, 271, and 272 may be magnets, but are not limited thereto. Although
The holder 1 may include the attaching member 181 at a first position and the cradle 2 may include the attaching members 271 and 272 at a second position and a third position, respectively. In this case, the first position and the third position may be positions facing each other when the holder 1 is inserted into the cradle 2.
Since the attaching members 181, 271, and 272 are included in the holder 1 and the cradle 2, the holder 1 and the cradle 2 may be attached to each other more strongly even when the holder 1 is inserted into one side surface of the cradle 2. In other words, as the holder 1 and the cradle 2 further include the attaching members 181, 271, and 272 in addition to the terminals 170 and 260, the holder 1 and the cradle 2 may be attached to each other more strongly. Therefore, even when there is no separate component (e.g., a lid) in the cradle 2, the inserted holder 1 may not be easily separated from the cradle 2.
Also, when the control unit 220 also determines that the holder 1 is completely inserted into the cradle 2 through the terminals 170 and 260 and/or the attaching members 181, 271, and 272, the control unit 220 may charge the battery 110 of the holder 1 by using power of the battery 210.
Referring to
As shown in
As shown in
Also, even when the holder 1 is tilted, the terminal 170 of the holder 1 and the terminal 260 of the cradle 2 are coupled with each other. Therefore, the heater 130 of the holder 1 may be heated by power supplied by the battery 210 of the cradle 2. Therefore, the holder 1 may generate aerosol by using the battery 210 of the cradle 2 even when the remaining power of the battery 110 of the holder 1 is low or the battery 110 of the holder 1 is completely discharged.
Also, when it is determined that the holder 1 titled through the terminals 170 and 260 and/or the attaching members 181, 271, and 272, the control unit 220 may heat the heater 130 of the holder 1 or charge the battery 110 by using power of the battery 210.

The control unit 220 of the cradle 2 may determine whether the holder 1 and the cradle 2 are coupled with each other and whether the holder 1 is tilted. When the holder 1 and the cradle 2 are coupled with each other, the control unit 220 may control charging of the battery 110 by the battery 210.

The holder 1 may be operated based on a smoking pattern and a smoking restriction condition. The smoking pattern may include, for example, the number of puffs for the inserted cigarette 3. The smoking restriction condition may include the puff limit number.

On the other hand, even when the holder 1 is tilted and separated by the user, the control unit 120 may accumulate and sum the number of counted puffs in the tilted state and the counted number of puffs in the separated state and compare the total number of puffs with a puff limit number, thereby determining whether to heat the heater (130 in
In operation 5110, the holder 1 or cradle 2 receives a smoking initiation request from a user. The smoking initiation request may be received from the user via an input device provided in the holder 1 or cradle 2. The control unit 120 of the holder 1 or the control unit 220 of the cradle 2 may determine that a smoking initiation request is received when there is an user input. On the other hand, smoking may be performed when the holder 1 is tilted or the holder 1 is separated from the cradle 2. However, when the holder 1 is neither separated from the cradle 2 nor tilted, the holder 1 may operate to prevent the user from smoking, and may not operate a heater or operate the heater only to a temperature or a heating time that is not sufficient for the user to smoke. Hereinafter, the operation of the holder 1 will be described on the assumption that the holder 1 is tilted or separated from the cradle 2.
In operation 5120, the control unit 120 of the holder 1 determines whether the holder 1 coupled with the cradle 2 is tilted. On the other hand, the control unit 220 of the cradle 2 may also determine whether the holder 1 is tilted. When the holder 1 is tilted, the method proceeds to operation 5130. However, when the holder 1 is separated, the method proceeds to operation 5170.
In operation 5130, the control unit 120 of the holder 1 counts the number of puffs in the tilted state.
In operation 5140, the control unit 120 of the holder 1 sums the number of puffs in the tilted state and the number of puffs in the separated state. When the user puffs the cigarette 3 only in the tilted state, the number of puffs in the separated state is zero.
In operation 5150, the control unit 120 of the holder 1 compares the total number of puffs with a preset puff limit number. For example, the puff limit number may be 14, but is not limited thereto. When the total number of puffs is less than or equal to the puff limit number, the method proceeds to operation 5120. However, when the total number of puffs reaches the puff limit number, the method proceeds to operation 5160.
In operation 5160, the control unit 120 of the holder 1 controls the heater 130 to stop heating the heater (130 in
In operation 5170, when the holder 1 is separated from the cradle 2, the control unit 120 of the holder 1 counts the number of puffs in the separated state. Accordingly, in operation 5140, the control unit 120 of the holder 1 may count the total number of puffs by summing the number of counted puffs in the separated state and the number of counted puffs in the tilted state.
In operation 5210, the holder 1 or cradle 2 receives a smoking initiation request from a user.
In operation 5220, the control unit 120 of the holder 1 determines whether the holder 1 coupled with the cradle 2 is tilted. On the other hand, the control unit 220 of the cradle 2 may also determine whether the holder 1 is tilted. When the holder 1 is tilted, the method proceeds to operation 5230. However, when the holder 1 is separated, the method proceeds to operation 5270.
In operation 5230, the control unit 120 of the holder 1 measures an operation time in the tilted state.
In step 2615240, the control unit 120 of the holder 1 adds up the operation time in the tilted state and the operation time in the separated state. When a user operated the holder 1 only when the holder 1 is tilted, the operation time in the separated state is 0 hours.
In operation 5150, the control unit 120 of the holder 1 compares the total operation time with a preset operation limit time. For example, the operation limit time may be 10 minutes, but is not limited thereto. When the total operation time is less than or equal to the operation limit time, the method proceeds to operation 5220. However, when the total operation time reaches the operation limit time, the method proceeds to operation 5260.
In operation 5260, the control unit 120 of the holder 1 controls the heater 130 to stop heating the heater (130 in
In operation 5270, when the holder 1 is separated from the cradle 2, the control unit 120 of the holder 1 measures the operation time in the separated state. Accordingly, in operation 5240, the control unit 120 of the holder 1 may measure the total number of puffs by summing the operation time in the separated state and the operation time in the tilted state.
On the other hand, when at least one of the number of puffs described in
In detail, when smoking is performed in a first state and then performed later in a second state, the holder accumulates a smoking pattern monitored in the second state to a smoking pattern monitored in the first state and, when an accumulated smoking pattern satisfies a smoking restriction condition, the holder 1 controls the heater (130 in

The user may puff eight more times by using the separated holder 1. At this time, the control unit 120 of the holder 1 may cumulatively count a first puff performed by using the separate holder 1 as a seventh subsequent to the sixth puff in the tilted state. In other words, the control unit 120 of the holder 1 may cumulatively count all puffs performed while the holder 1 is being tilted and being separated. When a cumulative total number of puffs reaches the puff limit number (i.e., when a fourteenth puff is completed), the control unit 120 of the holder 1 may terminate the operation of the holder 1.
Referring to
The user may puff ten more times by using the tilted holder 1. At this time, the control unit 120 of the holder 1 may cumulatively count a first puff performed by using the titled holder 1 as a fifth subsequent to the fourth puff in the separated state. In other words, the control unit 120 of the holder 1 may cumulatively count all puffs performed while the holder 1 is being separated and being tilted. When a cumulative total number of puffs reaches the puff limit number (i.e., when a fourteenth puff is completed), the control unit 120 of the holder 1 may terminate the operation of the holder 1.

In other words, the control unit 120 of the holder 1 cumulatively may count the number of puffs performed after initiation of smoking regardless of whether the holder 1 is tilted or separated and control the operation of the holder 1 based on an accumulated total number of puffs.

A method for generating aerosols shown in
In operation 5310, the holder 1 determines whether it is inserted in the cradle 2. For example, the control unit 120 may determine whether the holder 1 is inserted into the cradle 2 based on whether the terminals 170 and 260 of the holder 1 and the cradle 2 are connected to each other and/or whether the attaching members 181, 271, and 272 are operating.
When the holder 1 is inserted into the cradle 2, the method proceeds to operation 5320. When the holder 1 is separated from the cradle 2, the method proceeds to operation 5330.
In operation 5320, the cradle 2 determines whether the holder 1 is tilted. For example, the control unit 220 may determine whether the holder 1 is inserted into the cradle 2 based on whether the terminals 170 and 260 of the holder 1 and the cradle 2 are connected to each other and/or whether attaching members 182, 273, and 274 are operating.
Although it is described that the cradle 2 determines whether the holder 1 is tilted in operation 5320, the present disclosure is not limited thereto. In other words, the control unit 120 of the holder 1 may determine whether the holder 1 is tilted.
When the holder 1 is tilted, the method proceeds to operation 5340. When the holder 1 is not tilted (i.e., the holder 1 is completely inserted into the cradle 2), the method proceeds to operation 5370.
In operation 5330, the holder 1 determines whether conditions of using the holder 1 are satisfied. For example, the control unit 120 may determine whether the conditions for using the holder 1 are satisfied by checking whether the remaining power of the battery 110 and whether other components of the holder 1 may be normally operated.
When the conditions for using the holder 1 are satisfied, the method proceeds to operation 5340. Otherwise, the method is terminated.
In operation 5340, the holder 1 informs a user that the holder 1 is ready to be used. For example, the control unit 120 may output an image indicating that the holder 1 is ready to be used on the display of the holder 1 or may control the motor of the holder 1 to generate a vibration signal.
In operation 5350, the heater 130 is heated. For example, when the holder 1 is separated from the cradle 2, the heater 130 may be heated by power of the battery 110 of the holder 1. In another example, when the holder 1 is tilted, the heater 130 may be heated by power of the battery 210 of the cradle 2.
The control unit 120 of the holder 1 or the control unit 220 of the cradle 2 may check the temperature of the heater 130 in real time and control an amount of power supplied to the heater 130 and a time for supplying the power to the heater 130. For example, the control unit 120 or 220 may check the temperature of the heater 130 in real time through a temperature sensor included in the holder 1 or an electrically conductive track of the heater 130.
In operation 5360, the holder 1 performs an aerosol generation mechanism. For example, the control unit 120, 220 may check the temperature of the heater 130, which changes as a user performs puffs, and adjust an amount of power supplied to the heater 130 or stop supplying power to the heater 130. Also, the control unit 120 or 220 may count the number of puffs of the user and output information indicating that the holder 1 needs to be cleaned when the number of puffs reaches a certain number of times (e.g., 1500).
In operation 5370, the cradle 2 performs charging of the holder 1. For example, the control unit 220 may charge the holder 1 by supplying power of the battery 210 of the cradle 2 to the battery 110 of the holder 1.
Meanwhile, the control unit 120 or 220 may stop the operation of the holder 1 according to the number of puffs of the user or the operation time of the holder 1. Hereinafter, an example in which the control unit 120 or 220 stops the operation of the holder 1 will be described with reference to
A method for generating aerosols shown in
In operation 5410, the control unit 120 or 220 determines whether a user puffed. For example, the control unit 120 or 220 may determine whether the user puffed through the puff detecting sensor included in the holder 1. Alternatively, the control unit 120 or 220 may determine whether the user puffed by using the resistance change of the electrically conductive track included in the heater 130. Here, the electrically conductive track includes an electrically conductive track for generating heat and/or an electrically conductive track for sensing temperature. Alternatively, the control unit 120 or 220 may determine whether the user puffed by using both the resistance change of the electrically conductive track included in the heater 130 and the puff detecting sensor.
In operation 5420, aerosol is generated according to the puff of the user. The control unit 120 or 220 may adjust power supplied to the heater 130 according to the puff of the user the temperature of the heater 130, as described above with reference to
In operation 5430, the control unit 120 or 220 determines whether the number of puffs of the user equal to or greater than a puff limit number. For example, assuming that the puff limit number is set to 14, the control unit 120 or 220 determines whether the number of counted puffs is 14 or more. However, the puff limit number is not limited to 14. For example, the puff limit number may be set to an appropriate number of times from 10 to 16.
On the other hand, when the number of puffs of the user is close to the puff limit number (e.g., when the number of puffs of the user is 12), the control unit 120 or 220 may output a warning signal through a display or a vibration motor.
When the number of puffs of the user is equal to or greater than the puff limit number, the method proceeds to operation 5450. When the number of puffs of the user is less than the puff limit number, the method proceeds to operation 5440.
In operation 5440, the control unit 120 or 220 determines whether the operation time of the holder 1 is equal to or greater than an operation limit time. Here, the operation time of the holder 1 refers to accumulated time from a time point at which the holder 1 started its operation to a current time point. For example, assuming that the operation limit time is set to 10 minutes, the control unit 120 or 220 determines whether the holder 1 is operating for 10 minutes or longer.
On the other hand, when the operation time of the holder 1 is close to the operation limit time (e.g., when the holder 1 is operating for 8 minutes), the control unit 120 or 220 may output a warning signal through a display or a vibration motor.
When the holder 1 is operating for the operation limit time or longer, the method proceeds to operation 5450. When the operation time of the holder 1 is less than the operation limit time, the method proceeds to operation 5420.
In operation 5450, the control unit 120 or 220 forcibly terminates the operation of the holder 1. In other words, the control unit 120 or 220 terminates the aerosol generation mechanism of the holder 1. For example, the control unit 120 or 220 may forcibly terminate the operation of the holder 1 by interrupting the power supplied to the heater 130.

Although not shown in
In operation 5510, the control unit 220 of the cradle 2 determines whether the button 240 is pressed. When the button 240 is pressed, the method proceeds to operation 5520. When the button 240 is not pressed, the method proceeds to operation 5530.
In operation 5520, the cradle 2 indicates the status of the battery 210. For example, the control unit 220 may output information regarding the current state of the battery 210 (e.g., remaining power, etc.) on the display 250.
In operation 5530, the control unit 220 of the cradle 2 determines whether a cable is connected to the cradle 2. For example, the control unit 220 determines whether a cable is connected to an interface (e.g., a USB port, etc.) included in the cradle 2. When a cable is connected to the cradle 2, the method proceeds to operation 5540. Otherwise, the method is terminated.
In operation 5540, the cradle 2 performs a charging operation. For example, the cradle 2 charges the battery 210 by using power supplied through a connected cable.
As described above with reference to
Hereinafter, an example of a cigarette that may be inserted into the holder 1 will be described with reference to
Referring to
The cigarette 3 may be similar to a typical burning cigarette. For example, the cigarette 3 may include a first portion 310 containing an aerosol generating material and a second portion 320 including a filter and the like. Meanwhile, the cigarette 3 according to one embodiment may also include an aerosol generating material in the second portion 320. For example, an aerosol generating material in the form of granules or capsules may be inserted into the second portion 320.
The entire first portion 310 may be inserted into the holder 1 and the second portion 320 may be exposed to the outside. Alternatively, only a portion of the first portion 310 may be inserted into the holder 1 or the entire first portion 310 and a portion the second portion 320 may be inserted into the holder 1.
A user may inhale the aerosol while holding the second portion 320 by his/her lips. At this time, the aerosol is generated by as the outside air passes through the first portion 310, and the generated aerosol passes through the second portion and is delivered to a user's mouth.
The outside air may be introduced (1120) through at least one air passage formed in the holder 1. For example, the opening and closing of the air passage formed in the holder 1 and/or the size of the air passage may be adjusted by a user. Accordingly, an amount of smoke and a smoking impression may be adjusted by the user.
Alternatively, the outside air may be introduced (1110) through at least one hole formed in the surface of the cigarette 3.

A fifth wrapper 345 of
On the other hand, a sixth wrapper 346 of
The first wrapper 341 and the second wrapper 342 may be fabricated using a general filter wrapping paper. For example, the first wrapper 341 and the second wrapper 342 may include a porous wrapping paper or a non-porous wrapping paper. Also, the first wrapper 341 and the second wrapper 342 may be made of an oil-resistant paper sheet and an aluminum laminate packaging material.
The third wrapper 343 may be made of a hard wrapping paper. For example, the basis weight of the third wrapper 343 may be, but is not limited to, 90 g/m2.
The fourth wrapper 344 may be made of an oil-resistant hard wrapping paper. For example, the basis weight of the fourth wrapper 344 may be 92 g/m2 and the thickness thereof may be 125 μm, but the present disclosure is not limited thereto.
The fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347 may be made of a sterilized paper (MFW). Here, the MFW refers to a paper specially manufactured to have the tensile strength, the water resistance, the smoothness, and the like that are improved compared to those of ordinary paper. For example, the basis weight of the fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347 may be 60 g/m2 and the thickness thereof may be 67 m, but the present disclosure is not limited thereto. Also, the tensile strengths of the fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347 may be within the range from 8 kgf/15 mm to 11 kgf/15 mm for dry type and may be 1.0 kgf/15 mm for wet type, but the present disclosure is not limited thereto.
A predetermined material may be included in the fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347. Here, an example of the predetermined material may be, but is not limited to, silicon. For example, silicon exhibits characteristics like heat resistance with little change due to the temperature, oxidation resistance, resistances to various chemicals, water repellency, electrical insulation, etc. However, any material other than silicon may be applied to (or coated on) the fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347 without limitation as long as the material exhibits the above-mentioned characteristics.
The fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347 may prevent the cigarette 3 from being burned. For example, when the tobacco rod 310 is heated by the heater 130, there is a possibility that the cigarette 3 is burned. In detail, when the temperature is raised to a temperature above the ignition point of any one of materials included in the tobacco rod 310, the cigarette 3 may be burned. Even in this case, since the fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347 include a non-combustible material, the burning of the cigarette 3 may be prevented.
Furthermore, the fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347 may prevent the holder 1 from being contaminated by substances formed by the cigarette 3. Through puffs of a user, liquid substances may be formed in the cigarette 3. For example, as the aerosol formed by the cigarette 3 is cooled by the outside air, liquid materials (e.g., moisture, etc.) may be formed. As the fifth wrapper 345, the sixth wrapper 346, and the seventh wrapper 347 wrap the tobacco rod 310 and/or the first filter segment 321, the liquid materials formed in the cigarette 3 may be prevented from being leaked out of the cigarette 3. Accordingly, the casing 140 of the holder 1 and the like may be prevented from being contaminated by the liquid materials formed by the cigarette 3.
The diameter of the cigarette 3 may be within the range from 5 mm to 9 mm, and the length thereof may be about 48 mm. However, the present disclosure is not limited thereto. Preferably, the diameter of the cigarette 3 may be 7.2 mm, but is not limited thereto. In addition, the length of the tobacco rod 310 may be about 12 mm, the length of the first filter segment 321 may be about 10 mm, the length of the cooling structure 322 may be about 14 mm, and the length of the second filter segment 323 may be about 12 mm, but the present disclosure is not limited thereto.
The structures of the cigarette 3 shown in
The tobacco rod 310 includes an aerosol generating material. For example, the aerosol generating material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.
In addition, the tobacco rod 310 may include other additive materials like a flavoring agent, a wetting agent, and/or an organic acid. For example, the flavoring agent may include licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascara, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil, cinnamon, keragene, cognac, jasmine, chamomile, menthol, cinnamon, ylang ylang, salvia, spearmint, ginger, coriander, coffee, etc. In addition, the wetting agent may include glycerin or propylene glycol.
For example, the tobacco rod 310 may be filled with cut tobacco leaves. Here, cut tobacco leaves may be formed by fine-cutting a tobacco sheet.
For a large wide tobacco sheet to be filled within the tobacco rod 310 having a narrow space, a special operation for facilitating folding of the tobacco sheet is further needed. Therefore, it is easier to fill the tobacco rod 310 with cut tobacco leaves compared to filling the tobacco rod 310 with a tobacco sheet, and thus the productivity and the efficiency of the process for producing the tobacco rod 310 may be improved.
In another example, the tobacco rod 310 may be filled with a plurality of cigarette strands formed by fine-cutting a tobacco sheet. For example, the tobacco rod 310 may be formed by combining a plurality of tobacco strands in the same direction (parallel to one another) or randomly. In detail, the tobacco rod 310 may be formed by combining a plurality of tobacco strands, and a plurality of vertical channels through which the heater 130 may be inserted or aerosol may pass may be formed. At this time, depending on the sizes and arrangements of the tobacco strands, the vertical channels may be uniform or non-uniform.
For example, tobacco strands may be formed through the following operations. First, a raw tobacco material is pulverized to form a slurry in which an aerosol generating material (e.g., glycerin, propylene glycol, etc.), a flavoring liquid, a binder (e.g., guar gum, xanthan gum, carboxymethyl cellulose (CMC), etc.), and water are mixed, and then a sheet is formed by using the slurry. When forming the slurry, natural pulp or cellulose may be added to modify the physical properties of tobacco strands, and one or more binders may be mixed and used. Next, after drying the sheet, tobacco strands may be formed by fold-cutting or fine-cutting the dried sheet.
The raw tobacco material may be tobacco leaf fragments, tobacco stems, and/or fine tobacco powders formed during treatment of tobacco. The tobacco sheet may also include other additives like wood cellulose fibers.
The slurry may contain 5% to 40% aerosol generating material, and 2% to 35% aerosol generating material may remain in completed tobacco strands. Preferably, 10% to 25% of the aerosol generating material may remain in the completed tobacco strands.
Also, before the tobacco rod 310 is packaged by the first wrapper 341, a flavoring liquid like a menthol or a moisturizer may be spray-added to the center of the tobacco rod 310.
The tobacco strands may be fabricated to have cuboidal shapes having horizontal lengths from 0.5 mm to 2 mm, vertical lengths from 5 mm to 50 mm, and thicknesses (heights) from 0.1 mm to 0.3 mm, but the present disclosure is not limited thereto. Preferably, the tobacco strands may be fabricated to have a cuboidal shape having the horizontal length of 0.9 mm, the vertical length of 20 mm, and the thickness (height) of 0.2 mm. Also, one tobacco strand may be fabricated to have a basis weight from 100 g/m2 to 250 g/m2, but the present disclosure is not limited thereto. Preferably, one tobacco strand may be fabricated to have a basis weight of 180 g/m2.
Compared to the tobacco rod 310 filled with a cigarette sheet, the tobacco rod 310 filled with tobacco strands may generate a greater amount of aerosol. In the case of filling the same space, compared to a tobacco sheet, tobacco strands ensure a wider surface area. A wider surface area indicates that an aerosol generating material has a greater chance of contacting the outside air. Therefore, when the tobacco rod 310 is filled with tobacco strands, more aerosol may be generated as compared to the tobacco rod 310 filled with a tobacco sheet.
Furthermore, when the cigarette 3 is separated from the holder 1, the tobacco rod 310 filled with tobacco strands may be separated more easily than the tobacco rod 310 filled with a tobacco sheet. In other words, when the tobacco rod 310 is filled with tobacco strands, the tobacco rod 310 may be more easily separated from the holder 1 than the tobacco sheet 310 filled with a tobacco sheet.
The first filter segment 321 may be a cellulose acetate filter. For example, the first filter segment 321 may have a tubular structure including a hollowness therein. The length of the first filter segment 321 may be any suitable length within the range from 4 mm to 30 mm, but is not limited thereto. Preferably, the length of the first filter segment 321 may be 10 mm, but is not limited thereto.
The diameter of the hollowness included in the first filter segment 321 may be any suitable diameter within the range from 3 mm to 4.5 mm, but is not limited thereto.
The hardness of the first filter segment 321 may be adjusted by adjusting the content of a plasticizer in during fabrication of the first filter segment 321.
To prevent the size of the first filter segment 321 from decreasing over time, the first filter segment 321 may be wrapped by a wrapper. Therefore, the first filter segment 321 may be easily combined with other components (e.g., other filter segments).
Also, the first filter segment 321 may be fabricated by inserting structures of the same type or different types like films or tubes thereinto (e.g., into the hollowness).
The first filter segment 321 may be fabricated using cellulose acetate. Therefore, the inner material of the tobacco rod 310 may be prevented from being pushed back when the heater 130 is inserted, and the effect of cooling an aerosol may occur.
The second filter segment 323 may also be a cellulose acetate filter. For example, the second filter segment 323 may be fabricated as a recess filter, but is not limited thereto. The length of the second filter segment 323 may be appropriately selected within the range from 4 mm to 20 mm. For example, the length of the second filter segment 323 may be about 12 mm, but is not limited thereto.
The second filter segment 323 may be fabricated to generate a flavor by spraying a flavoring liquid to the second filter segment 323 during fabrication of the second filter segment 323. Alternatively, separate fibers coated with a flavoring liquid may be inserted into the second filter segment 323. Aerosol formed in the tobacco rod 310 is cooled as it passes through the cooling structure 322, and the cooled aerosol is delivered to a user through the second filter segment 323. Therefore, when a flavoring material is added to the second filter segment 323, the effect of enhancing the persistence of a flavor delivered to the user may occur.
Also, the second filter segment 323 may include at least one capsule 324. Here, the capsule 324 may have a structure in which a content liquid containing a flavoring material is wrapped with a film. For example, the capsule 324 may have a spherical or cylindrical shape.
The film of the capsule 324 may be fabricated by using a material including agar, pectin, sodium alginate, carrageenan, gelatin, or a gum like guar gum. Furthermore, a gelling agent may be further used as a material for forming the film of the capsule 324. Here, as the gelling agent, for example, a calcium chloride group may be used. Furthermore, a plasticizer may be further used as a material for forming the film of the capsule 324. As the plasticizer, glycerin and/or sorbitol may be used. Furthermore, a coloring agent may be further used as a material for forming the film of the capsule 324.
For example, as a flavoring material included in the content liquid of the capsule 324, menthol, plant essential oil, and the like may be used. As a solvent of the flavoring material included in the content liquid, for example, a medium chain fatty acid triglyceride (MCT) may be used. Also, the content liquid may include other additives like a figment, an emulsifying agent, a thickening agent, etc.
The cooling structure 322 cools aerosol generated as the heater 130 heats the tobacco rod 310. Therefore, a user may inhale aerosol cooled to a suitable temperature.
The cooling structure 322 may cool aerosol by using the phase change phenomenon. For example, a material constituting the cooling structure 322 may cause a phase change action, such as melting or glass transition that needs absorption of thermal energy. As such a heat-absorbing reaction occurs at a temperature at which aerosol enters the cooling structure 322, the temperature of the aerosol passing through the cooling structure 322 is dropped.
The length or the diameter of the cooling structure 322 may vary depending on the shape of the cigarette 3. For example, the length of the cooling structure 322 may be suitably selected within the range from 7 mm to 20 mm. Preferably, the length of the cooling structure 322 may be about 14 mm, but is not limited thereto.
The cooling structure 322 may be fabricated using a polymer material or a biodegradable polymer material. For example, the polymer material includes, but is not limited to, gelatin, polyethylene (PE), polypropylene (PP), polyurethane (PU), fluorinated ethylene propylene (FEP), and combinations thereof. Also, the biodegradable polymeric material includes, but is not limited to, polylactic acid (PLA), polyhydroxybutyrate (PHB), cellulose acetate, poly-epsilon-caprolactone (PCL), polyglycolic acid (PGA), polyhydroxyalkanoate (PHAs), and starch-based thermoplastic resins.
Preferably, the cooling structure 322 may include pure polylactic acid only. For example, the cooling structure 322 may be a 3-dimensional structure fabricated using at least one fiber strand including pure polylactic acid (hereinafter referred to as a ‘fiber strand’). Here, the thickness of the fiber strand, the length of the fiber strand, the number of fiber strands constituting the cooling structure 322, and the shape of the fiber strand may vary. As the cooling structure 322 is made of pure polylactic acid, certain materials may be prevented from being formed while aerosol passes through the cooling structure 322.
The cooling structure 322 may be fabricated through one or more operations, and an operation for wrapping the outer surfaces of the cooling structure 322 with a wrapper made of paper or a polymer material may be added. Here, the polymer material includes, but is not limited to, gelatin, polyethylene (PE), polypropylene (PP), polyurethane (PU), fluorinated ethylene propylene (FEP), and combinations thereof.
Hereinafter, with reference to
The cooling structure 322 may be fabricated by weaving at least one fiber bundle 3110 and/or 3120. As occasions demand, the fiber bundles 3110 and 3120 may be formed by using fiber strands coated with a flavoring liquid. Alternatively, the fiber bundles 3110 and 3120 may be formed by using a separate fiber strand coated with a flavoring liquid and fiber strands 3130 made of polylactic acid. In addition, the fiber strands 3130 may be dyed to a predetermined color, and the fiber bundles 3110 and 3120 may be formed by using the dyed fiber strands 3130.
The advantages of fabricating the cooling structure 3100 by using the fiber bundles 3110 and 3120 are as follows.
First, aerosol may flow between the fiber strands 3130 and a vortex may be formed depending on the shape of the cooling structure 3100. The vortex expands an area of contact of the aerosol in the cooling structure 3100 and increases the time that the aerosol stays in the cooling structure 3100. Therefore, heated aerosol may be effectively cooled.
Second, the cooling structure 3100 manufactured by using the fiber strands 3130 fabricated by using a raw material (e.g., polylactic acid) has a high yield relative to a typical prosthetic material. In other words, the cooling structure 3100 made of the fiber strands 3130 is easier to cut than a general prosthetic material. Therefore, since a large number of the cooling structures 3100 may be obtained by cutting a single cooling rod, the manufacturing yield is high as compared to the process for producing a prosthetic material.
Also, when a cooling structure is manufactured through extrusion molding or the like, the efficiency of the process is lowered due to the addition of operations like cutting of a structure. Also, there are limits in manufacturing a cooling structure in various shapes.
Third, the cooling structure 3100 manufactured by using the fiber strands 3130 facilitates cigarette production as compared to a film-type cooling structure. In other words, since a film-type cooling structure is easily crushed, it is difficult to insert the film-type cooling structure into the cigarette 3 having a small volume. On the other hand, the cooling structure 3100 manufactured by using fiber strands may be easily inserted into the cigarette 3.
Also, in case of inserting a film-type cooling structure into the cigarette 3, the film-type cooling structure may be crushed by an external impact. In this case, the aerosol cooling effect of the cooling structure is deteriorated.
As the cooling structure 3100 according to an embodiment is fabricated by using polylactic acid fibers (e.g., weaving), the risk of the cooling structure being deformed or losing function by an external impact may be reduced. Also, by changing the way of combining the fiber bundles 3110 and 3120, the cooling structure 3100 having various shapes may be fabricated.
Furthermore, by fabricating the cooling structure 3100 by using cooling fibers 3130, the surface area contacting with aerosol is increased. Therefore, the aerosol cooling effect of the cooling structure 3100 may be further improved.
Referring to
The number of fiber strands constituting main stream 3210 or sub stream 3220 is not limited. Therefore, the thickness of the main stream 3210 or the sub stream 3220 may vary according to the number of fiber strands.
Also, the sub streams 3220 connected to the main stream 3210 may not be aligned in any one direction. In other words, when the plurality of sub streams 3220 are included in the main stream 3210, orientations of the sub streams 3220 may be different from one another, or orientations of some of the sub streams 3220 may be different from one another.
Referring back to
Depending on the fabrication process of the cooling structure 322, the diameter of the channel may vary. For example, the diameter of the channel may be adjusted according to the thickness and/or the number of a fiber bundle constituting the cooling structure 322, or the diameter of the channel may be adjusted according to the woven pattern of the cooling structure 322.
Also, uniform channels may be distributed in the cooling structure 322. In other words, the cooling structure 322 may be fabricated, such that channels are uniformly distributed throughout cross-sections. Therefore, aerosol passing through the cooling structure 322 may flow smoothly.
Hereinafter, an example of the cooling structure 322 including a single vertical channel will be described with reference to
Referring to
For example, the number of fiber bundles constituting the cooling structure 3400 may be two or greater, and the number of the fiber bundles is not limited. Also, the number of fiber strands included in a single fiber bundle may be one or greater, and the number of the fiber strands is not limited. Also, the number of fiber strands included in respective fiber bundles may be the same or may differ.
Although
Meanwhile, the interiors of the channels of the cooling structures 3300, 3400, and 3500 shown in
The number of fiber strands filling the interiors of the cooling structure 3300, 3400, and 3500 may be adjusted for various purposes, and various modifications may be made in the shape of the cooling structure 3300, 3400, and 3500. For example, various types of the cooling structures 3300, 3400, and 3500 may be fabricated by changing the total area of fibers or the arrangement of fiber strands.
Hereinafter, referring to
The at least one channel formed in the first sub-structure 3610 may be filled with the second sub-structure 3620. For example,
The second sub-structure 3720 filling the channel of the first sub-structure 3710 may be a structure fabricated by weaving a plurality of fiber bundles.

As shown in
The protruding tube 10200 surrounds and protects the heater 10300 and functions to support the accommodating portion 10040 when the accommodating portion 10040 is coupled. Since the protruding tube 10200 has a hollow structure with an empty space therein, the protruding tube 10200 includes a combining path 10200h in which at least a portion of the accommodating portion 10040 may be inserted. The top of the combining path 10200h is connected to an opening 10200p that is opened upward outside of the aerosol generating apparatus.
The casing 10010 is provided with the heater 10300 for heating the cigarette 3. The heater 10300 is installed in the casing 10010 such that an end portion 10310 is located inside the protruding tube 10200. When the cigarette 3 is accommodated in the accommodating portion 10040 while the accommodating portion 10040 is being coupled with the protruding tube 10200, the end portion 10310 of the heater 10300 is inserted into the bottom surface of an end portion of the cigarette 3.
An electricity supply device 10700 disposed inside the casing 10010 is electrically connected to the bottom end portion of the heater 10300 through an electric wire 10710. When electricity of the electricity supply device 10700 is supplied to the heater 10300 while the cigarette 3 is being inserted into the end portion 10310 of the heater 10300, the heater 10300 is heated, and thus the cigarette 3 is heated.
Referring to
The size of the heater hole 10040c formed in the bottom wall 10040b of the accommodating portion 10040 may correspond to the thickness of the end portion 10310 of the heater 10300. For example, when the end portion 10310 of the heater 10300 has a circular cross-section, the heater hole 10040c also has a circular cross-sectional shape, wherein the heater hole 10040c is formed to have an inner diameter corresponding to the outer diameter of the end portion 10310 of the heater 10300.
The embodiment is not limited by the inner diameter of the heater hole 10040c. For example, the inner diameter of the heater hole 10040c may be larger than the outer diameter of the end portion 10310 of the heater 10300, and thus the inner surface of the heater hole 10040c may be apart from the outer surface of the end portion 10310 of the heater 10300.
The accommodating portion 10040 includes an outer wall 10040t surrounding the sidewall 10040w and apart outwardly in the radius-wise direction of the sidewall 10040w. When the accommodating portion 10040 is coupled with the protruding tube 10200, the protruding tube 10200 is inserted between the outer wall 10040t and the sidewall 10040w, and thus the coupled state of the accommodating portion 10040 and the protruding tube 10200 may be stably maintained.
The sidewall 10040w of the accommodating portion 10040 is inserted into the combining path 10200h of the protruding tube 10200 when the accommodating portion 10040 is coupled with the protruding tube 10200. The end portion 10310 of the heater 10300 located inside the protruding tube 10200 passes through the heater hole 10040c of the accommodating portion 10040 while the sidewall 10040w of the accommodating portion 10040 is moving downward along the combining path 10200h of the protruding tube 10200.
The end portion 10310 of the heater 10300 passes through the heater hole 10040c of the accommodating portion 10040 and is located inside the accommodating path 10040h of the accommodating portion 10040 while the accommodating portion 10040 is being coupled with the protruding tube 10200. The end portion 10310 of the heater 10300 is inserted into the cigarette 3 when the cigarette 3 is accommodated in the accommodating path 10040h of the accommodating portion 10040 while the accommodating portion 10040 is being coupled with the protruding tube 10200.
When a user of the aerosol generating apparatus inserts the cigarette 3 into the accommodating path 10040h, the cigarette 3 moves along the accommodating path 10040h and, when an end portion of the cigarette 3 reaches the bottom wall 10040b of the accommodating portion 10040, an impression that the end portion of the cigarette 3 contacts the bottom wall 10040b is transmitted to a hand of the user holding the cigarette 3. Therefore, the user may easily mount the cigarette 3 to the aerosol generating apparatus through a simple action of holding the cigarette 3 in his/her hand and pushing the cigarette 3 into the insertion hole 10040p of the accommodating path 10040h.
When the user separates the cigarette 3 from the accommodating portion 10040, the user may pull the cigarette 3 out of the accommodating portion 10040 by holding and turning the cigarette 3 by hand. The cigarette 3 and the heater 10300 adhered to each other via a tobacco material may be completely separated while the user is holding and turning the cigarette 3 by hand.
After the cigarette 3 is separated from the accommodating portion 10040, the user may perform a cleaning operation of the interior of the accommodating portion 10040. When the user removes the accommodating portion 10040 from the casing 20010 to perform the cleaning operation, the user may pull the accommodating portion 10040 out of the casing 20010 by holding the accommodating portion 10040 by hand.
A plurality of protruding portions 10050 for supporting the cigarette 3 are arranged to protrude from the inner wall of the combining path 10200h of the protruding tube 10200. The protruding portion 10050 contacts the outer surface of the cigarette 3 inserted into the accommodating portion 10040 by penetrating the sidewall 10040w of the accommodating portion 10040 coupled with the protruding tube 10200.
The protruding tube 10200 may also function to directly supply the outside air to an end portion of the cigarette 3. To this end, the protruding tube 10200 includes an air hole 10200g for communication between the inside and the outside of the protruding tube 10200. The air hole 10200g may be apart in the circumferential direction from the center of the protruding tube 10200 in the lengthwise direction, and a plurality of air holes 10200g may be provided. The air hole 10200g forms a flow path for the air, such that the outside air is introduced into the protruding tube 10200.
While the accommodating portion 10040 is being coupled with the protruding tube 10200, an air introduction gap 10040g for allowing the air outside the accommodating portion 10040 to flow into the accommodating portion 10040 is formed at a contacting portion between the accommodating portion 10040 and the protruding tube 10200, that is, between the outer wall 10040t of the accommodating portion 10040 and the protruding tube 10200. Therefore, as shown in
Referring to
The cigarette 3 has a cylindrical shape and the accommodating path 10040h of the accommodating portion 10040 also has a cylindrical shape in correspondence to the shape of the cigarette 3. The diameter of the accommodating path 10040h of the accommodating portion 10040 is larger than the diameter of the cigarette 3. Therefore, when the cigarette 3 is accommodated in the accommodating portion 10040, the outer surface of the cigarette 3 and the accommodating path 10040h of the accommodating portion 10040 are apart from each other. In other words, in
The accommodating portion 10040 also includes a through hole 10040d formed through the sidewall 10040w, such that the protruding portion 10050 passes therethrough. The protruding portion 10050 is formed to protrude from the surface of the accommodating path 10040h toward the cigarette 3 to contact the outer surface of the cigarette 3.
The protruding portions 10050 are arranged apart from one another on the outer surface of the cigarette 3 in the circumferential direction with respect to the center of the cigarette 3, such that a flow path through which the second airflow 10000g passes is formed between the protruding portions 10050. A plurality of through holes 10040d are formed in correspondence to the number of the protruding portions 10050. Although the protruding portions 10050 support the outer surface of the cigarette 3, the air may freely flow inside the accommodating path 10040h of the accommodating portion 10040, because the protruding portions 10050 adjacent to each other are apart from each other.
Although
Also, positions and shapes of the protruding portion 10050 and the through hole 10040d may vary. For example, the protruding portion 10050 may extend around the center of the cigarette 3, that is, in the circumferential direction, to contact a portion of the outer surface of the cigarette 3 around the cigarette 3, that is, in the circumferential direction, toward the center of the cigarette 3. Even when the protruding portions 10050 extends in the circumferential direction, the protruding portions 10050 adjacent to each other may be separated from each other to form a flow path through which the air passes in the accommodating path 10040h.
The end portion of the protruding portion 10050 contacting the outer surface of the cigarette 3 may be formed as a concave curved cylindrical surface in correspondence to the shape of the outer surface of the cigarette 3.
Referring to
An aligning inclined surface 10040y that aligns the position of the cigarette 3 accommodated in the accommodating portion 10040 to the center of the accommodating portion 10040 by guiding edges of the end portion of the cigarette 3 is installed on edges of the top surface of the accommodating portion 10040 facing toward the bottom wall 10040b of the accommodating path 10040h.
Referring to
When the cigarette 3 is inserted into the accommodating path 10040h, moves along the accommodating path 10040h, and the end portion of the cigarette 3 reaches the position of the protruding portion 10050 protruding from the accommodating path 10040h, the inclined surface 10050d of the protruding portion 10050 guides movement of the cigarette 3, such that the end portion of the cigarette 3 may be inserted into the protruding portion 10050.
While the accommodating portion 10040 is being coupled with the protruding tube 10200 and the cigarette 3 is being inserted into the accommodating path 10040h of the accommodating portion 10040, the accommodating path 10040h is connected to the outside via the insertion hole 10040p, and thus an external second airflow 10000g flows into the accommodating path 10040h of the accommodating portion 10040 through the insertion hole 10040p. Also, a first airflow 10000f passed through the air introduction gap 10040g passes through the air hole 10200g of the protruding tube 10200 and reaches the outer surface of the end portion of the cigarette 3 accommodated in the accommodating portion 10040.
The cigarette 3 is supported by the protruding portions 10050 and the outer surface of the end portion of the cigarette (3) is not in contact with any component, the outer surface of the end portion of the cigarette 3 is surrounded by the air. When aerosol particles are generated from the cigarette 3 as the heater 10300 heats the cigarette 3 and a user inhales the air through his/her mouth by holding the cigarette 3 between his/her lips, the air around the outer surface of the end portion of the cigarette 3 pass through cigarette 3, and thus an air flow including the aerosol particles may be delivered to the user.
In the aerosol generating apparatus according to the embodiment shown in
Also, after using the cigarette 3, the user may pull the cigarette 3 out of the casing 10010 by holding and turning the cigarette 3 by hand.
Also, the user may separate the cover 10020 from the casing 10010 and separate the accommodating portion 10040 from the casing 10010 for a cleaning operation.
Since the protruding tube 10200 and the heater 10300 are exposed to the outside after the accommodating portion 10040 is completely separated from the casing 10010, the user may directly check states of the protruding tube 10200 and the heater 10300 and easily perform a cleaning operation.
Also, the protruding portions 10050 protruding inside of the accommodating path 10040h contact the outer surface of the cigarette 3 while the cigarette 3 is being inserted into the accommodating path 10040h of the accommodating portion 10040 attached to the casing 10010 of the aerosol generating apparatus, and thus the protruding portions 10050 stably support the cigarette 3. Therefore, while the aerosol generating apparatus is being used, the cigarette 3 is not separated from the aerosol generating apparatus and the state in which the cigarette 3 is accommodated in the accommodating path 10040h of the aerosol generating apparatus is stably maintained, and thus a user may enjoy the aerosol generating apparatus.
Also, as the protruding portions 10050 of the accommodating path 10040h of the accommodating portion 10040 contact portions of the outer surface of the cigarette 3, an air flow path in which the air may pass is formed between the accommodating path 10040h and the cigarette 3, and thus the outside air for assisting generation of aerosol may be supplied smoothly and sufficiently into the interior of the aerosol generating apparatus.
In the aerosol generating apparatus according to the embodiment shown in
In
A plurality of lower protruding portions 10050 are arranged and are apart from one another on the outer surface of the cigarette 3 in the circumferential direction with respect to the center of the cigarette 3.
A plurality of upper protruding portions 10050b are also arranged and are apart from one another on the outer surface of the cigarette 3 in the circumferential direction with respect to the center of the cigarette 3.
The through hole 10040d formed in the sidewall 10040w of the accommodating portion 10040 is formed to extend in the lengthwise direction of the accommodating path 10040h to accommodate both the upper protruding portions 10050b and the lower protruding portions 10050.
The plurality of protruding portions 10050 and 10050b are apart from each other on the outer surface of the cigarette 3 in the circumferential direction with respect to the center of the cigarette 3 and are apart from each other on the outer surface of the cigarette 3 in the lengthwise direction of the cigarette 3, a flow path through which the air flows is formed between the protruding portions 10050 and 10050b adjacent to each other.
In the aerosol generating apparatus according to the embodiment shown in
In the aerosol generating apparatus according to the embodiment shown in
A plurality of bottom protrusions 10040k are arranged on the bottom wall 10040b to be apart from one other in the circumferential direction with respect to the center of a heater hole 10040c formed in the bottom wall 10040b. Therefore, since the air may pass through the space between the bottom protrusions 10040k adjacent to each other, the air introduced from the outside into the accommodating path 10040h through the insertion hole 10040p of the accommodating path 10040h is supplied to the bottom surface of the end portion of the cigarette 3 through the space between the bottom protrusions 10040k.

After the cigarette 3 is removed from the aerosol generating apparatus after smoking and a cleaning operation is to be performed, the cover 20020 and the accommodating portion 20040 may be separated from the casing 20010 together. In other words, when a user holds the cover 20020 by hand and separates the cover 20020 and the accommodating portion 20040 from the casing 20010, the cover 20020 and the accommodating portion 20040 are separated from the casing 20010 together.
The protruding tube 20200 surrounds and protects the heater 10300 and functions to support the accommodating portion 20040 and the cover 20020 when the accommodating portion 20040 is coupled with the protruding tube 20200. Since the protruding tube 20200 has a hollow structure with an empty space therein, the protruding tube 20200 includes a combining path 20200h in which at least a portion of the accommodating portion 20040 may be inserted. The top of the combining path 20200h is connected to an opening 20200p that is opened upward outside of the aerosol generating apparatus.
The protruding tube 20200 may also function to directly supply the outside air to an end portion of the cigarette 3. To this end, the protruding tube 20200 includes an air hole 20200g for communication between the inside and the outside of the protruding tube 20200. The air hole 20200g may be apart in the circumferential direction from the center of the protruding tube 20200 in the lengthwise direction, and a plurality of air holes 10200g may be provided. The air hole 20200g forms a flow path for the air, such that the outside air is introduced into the protruding tube 20200.
The accommodating portion 20040 may be inserted into a combining path 20200h of the protruding tube 20200 through the opening 20200p of the protruding tube 20200 and includes the accommodating path 20040h capable of accommodating the cigarette 3, an insertion hole 20040p which is opened outward from one end of the accommodating path 20040h for insertion of the cigarette 3 thereinto, and a bottom wall 20040b which closes the other end of the accommodating path 20040h and includes a heater hole 20040c through which the end portion 10310 of the heater 10300 passes.
The accommodating portion 20040 is formed integrally with the cover 20020. For example, the cover 20020 and the accommodating portion 20040 may be integrally formed through injection molding or a 3-dimensional printing method by using a material like plastic. Alternatively, the cover 20020 and the accommodating portion 20040 may be separately fabricated and attached to each other via screws or fixed to each other via a coupling members like bolts or an adhesive.

The cover 10020 coupled with a first end of the casing 10010 constitutes the outer appearance of the aerosol generating apparatus 10000 together with the casing 10010. The casing 10010 constitutes the outer appearance of the aerosol generating apparatus 10000 and accommodates various components in a space formed therein.
A locking device may be installed between the cover 10020 and the casing 10010 to maintain the attachment between the cover 10020 and the casing 10010. The locking device may include, for example, a magnet and a metal member that sticks to the magnet. When a magnet is used for the locking device, a magnet may be installed on either one of the cover 10020 and the casing 10010 and a metal that sticks to the magnet may be attached to the other one. Alternatively, magnets may be installed on both the cover 10020 and the casing 10010.
An outside hole 10020p through which the cigarette 3 may be inserted is formed on the top surface of the cover 10020. When the door 10030 slides in a straight line along the rail 10030r on the top surface of the cover 10020, the outside hole 10020p and the insertion hole 10040p through which the cigarette 3 may be inserted are exposed to the outside. The outside hole 10020p of the cover 10020 exposes the insertion hole 10040p of an accommodating path 10040h capable of accommodating the cigarette 3 to the outside.
When the outside hole 10020p is exposed to the outside by the door 10030, a user may insert an end portion 3b of the cigarette 3 into the outside hole 10020p and the insertion hole 10040p, thereby placing the cigarette 3 in the accommodating path 10040h formed inside the housing 10020.
A plurality of cigarette supporting protrusions 10020m, which are arranged apart from one another in the circumferential direction on the inner surface of the outside hole 10020p and protrude toward the center of the outside hole 10020p, are arranged in the outside hole 10020p of the cover 10020. The cigarette support protrusions 10020m pass through the outside hole 10020p and contact the outer surface of the cigarette 3 inserted in the insertion hole 10040p and the accommodating path 10040h to support the cigarette 3.
At the casing 10010, a button 10090 is provided. As the button 10090 is manipulated, the operation of the aerosol generating apparatus 10000 may be controlled.
An outside air introduction gap 10020g that allows the air to flow into the interior of the cover 10020 is formed at a portion where the cover 10020 contact the casing 10010 when the cover 10020 is coupled with the casing 10010.
When the user removes the cigarette 3 from the aerosol generating apparatus after using the cigarette 3, the user may hold and turn the cigarette 3 by hand and pull the cigarette 3 out of the casing 10010. Alternatively, when the user turns the cigarette 3 and then pulls the cover 10020, the cover 10020 may be separated from the casing 10010 together with the cigarette 3. As the cigarette 3 is separated from the casing 10010 by turning the cigarette 3, the attachment between the cigarette 3 and a heater is released and a tobacco material attached to the cigarette 3 may be discharged out of the casing 10010 together with the cigarette 3.
When the cover 1002 is pulled without turning the cigarette 3, the cigarette 3 is separated from the casing 10010, but a tobacco portion of the cigarette 3 (i.e., the first portion 310 of
The aerosol generating apparatus includes the casing 10010, the hollow-shaped protruding tube 10200 protruding from the first end 10010a of the casing 10010 and having an opening opened to the outside, the heater 10300 installed to the casing 10010 to be located inside the protruding tube 10200, and the accommodating portion 10040 that may be coupled with the protruding tube 10200 and may be separated from the protruding tube 10200.
After the cigarette 3 is separated from the aerosol generating apparatus, the user may carry out a cleaning operation to remove any tobacco material that may be remaining inside the aerosol generating apparatus. As shown in
The protruding tube 10200 surrounds and protects the heater 10300 and functions to support the accommodating portion 10040 when the accommodating portion 10040 is coupled. Since the protruding tube 10200 has a hollow structure with an empty space therein, the protruding tube 10200 includes a combining path 10200h in which at least a portion of the accommodating portion 10040 may be inserted. The top of the combining path 10200h forms an opening that is opened upward outside of the aerosol generating apparatus.
The protruding tube 10200 includes a guiding groove 10020n extending in a straight line in the lengthwise direction of the protruding tube 10200 to be coupled with the accommodating portion 10040.
The protruding tube 10200 may also function to directly supply the outside air to an end portion of the cigarette 3. To this end, the protruding tube 10200 includes an air hole 10200g for communication between the inside and the outside of the protruding tube 10200. The air hole 10200g is arranged to be connected to an end portion of the guiding groove 10020n. The air hole 10200g may be apart in the circumferential direction from the center of the protruding tube 10200 in the lengthwise direction, and a plurality of air holes 10200g may be provided. The air hole 10200g forms a flow path for the air, such that the outside air is introduced into the protruding tube 10200.
The casing 10010 is provided with the heater 10300 for heating the cigarette 3. The heater 10300 is installed in the casing 10010 such that an end portion is located inside the protruding tube 10200. When the cigarette 3 is accommodated in the accommodating portion 10040 while the accommodating portion 10040 is being coupled with the protruding tube 10200, the end portion of the heater 10300 is inserted into the bottom surface of an end portion of the cigarette 3.
Referring to
The heater hole 10040c formed in the bottom wall 10040b of the accommodating portion 10040 includes an outer hole 10040j recessed from the heater 10300 in the outward direction. Since a plurality of outer holes 10040j are apart from one another in the circumferential direction around the heater hole 10040c, the heater hole 10040c has a star-like shape. The outer hole 10040j functions as an air flow path that allows the air present around the heater 10300 outside the accommodating portion 10040 to be concentrated toward the cigarette 3 through the heater hole 10040c to facilitate introduction of the air into the accommodating portion 10040.
The accommodating portion 10040 includes an outer wall 10040t surrounding the sidewall 10040w and apart outwardly in the radius-wise direction of the sidewall 10040w. When the accommodating portion 10040 is coupled with the protruding tube 10200, the protruding tube 10200 is inserted between the outer wall 10040t and the sidewall 10040w, and thus the coupled state of the accommodating portion 10040 and the protruding tube 10200 may be stably maintained.
A guiding rib 10040n inserted into the guiding groove 10020n of the protruding tube 10200 when the accommodating portion 10040 is inserted into the protruding tube 10200 is installed in an outer wall 10040t.
The end portion of the heater 10300 passes through the heater hole 10040c of the accommodating portion 10040 and is located inside the accommodating path 10040h of the accommodating portion 10040 while the accommodating portion 10040 is being coupled with the protruding tube 10200. The heater 10300 is inserted into the cigarette 3 when the cigarette 3 is accommodated in the accommodating path 10040h of the accommodating portion 10040 while the accommodating portion 10040 is being coupled with the protruding tube 10200.
A plurality of bottom surface protrusions 10040e protruding from the bottom wall 10040b and apart from one another in the circumferential direction outside the heater hole 10040c are installed on the bottom surface of the bottom wall 10040b of the accommodating portion 10040. The bottom surface protrusions 10040e serve to secure an air flow path by maintaining a gap between the bottom wall 10040b and the aerosol generating apparatus when the accommodating portion 10040 is installed in the aerosol generating apparatus.
The bottom surface protrusions 10040e extend in the radial direction from the outer surface of the bottom wall 10040b toward the heater hole 10040c, and thus the air outside the bottom wall 10040b flows smoothly toward the outer hole 10040j of the heater hole 10040c through the space between the bottom surface protrusions 10040e adjacent to each other.
Due to the bottom surface protrusions 10040e, the air outside the bottom wall 10040b is uniformly supplied to the heater hole 10040c, and a uniform and constant amount of air is supplied to the cigarette 3. Therefore, aerosol having optimum flavor and aroma may be provided to a user.
An air induction groove 10040r extending from the outer end portion of the bottom wall 10040b to the heater hole 10040c is formed on the bottom surface of the bottom wall 10040b of the accommodating portion 10040. The air induction grooves 10040r provide a passageway for the mainstream of the air supplied to the cigarette 3 accommodated in the accommodating portion 10040.
An end portion of the air induction groove 10040r located at the outer end portion of the bottom wall 10040b is disposed at a position corresponding to the air hole 10200g shown in
A plurality of air induction grooves 10040r may be installed in correspondence to the number of the air holes 10200g formed in the protruding tube 10200.
The accommodating portion 10040 includes a discharging hole 10040a formed by cutting a portion of the sidewall 10040w to expose the accommodating path 10040h out of the sidewall 10040w. As the discharging hole 10040a is formed in the sidewall 10040w, the sidewall 10040w has an approximately semi-cylindrical shape. In other words, when the sidewall 10040w is cut in the direction crossing the lengthwise direction of the sidewall 10040w, the cross-sectional shape of the sidewall 10040w may be approximately semicircle.
In the embodiment shown in
A cleaning operation may be performed more easily by forming the discharging hole 10040a for exposing the accommodating path 10040h in the sidewall 10040w of the accommodating portion 10040.
A plurality of slits 10040s formed through the sidewall 10040w to connect the accommodating path 10040h to the outside of the accommodating portion 10040 are formed in the sidewall 10040w of the accommodating portion 10040. The slits 10040 bring the air that stays in the empty space formed between the outer wall 10040t and the sidewall 10040w into contact with portions of the outer surface of the cigarette 3 accommodated in the accommodating portion 10040.
The air staying in the empty space formed between the outer wall 10040t and the sidewall 10040w is heated by the cigarette 3 that is heated by the heater 10300 and may flow back into the accommodating path 10040h through the heater hole 10040c or may be introduced toward the cigarette 3 through the slits 10040s for assisting generation of aerosol.
Also, the air staying in the empty space formed between the outer wall 10040t and the sidewall 10040w may perform heat insulation function for preventing the heat of the cigarette 3 from being directly transmitted to the user via the accommodating portion 10040 by absorbing some of the heat of the cigarette 3.
Referring to
As the sidewall 10040w forms the slope as described above, the size of the accommodating path 10040h of the accommodating portion 10040 may vary in the lengthwise direction of the cigarette 3. A diameter D1 of the accommodating path 10040h in which a middle portion of the cigarette 3 is accommodated is greater than a diameter D2 of the accommodating path 10040h in which the lower end portion of the cigarette 3 is accommodated. The diameter-variable structure of the accommodating path 10040h allows the center of the cigarette 3 to be precisely aligned with the center of the heater 10300 during an operation in which the cigarette 3 is accommodated in the accommodating portion 10040. In addition, when the cigarette 3 is completely inserted into the accommodating path 10040h, the lower end portion of the cigarette 3 is strongly pressed by the sidewall 10040w, and thus the state in which the cigarette 3 is inserted into the accommodating path 10040h may be stably maintained.
A user may directly remove the cigarette from the accommodating portion 10040 after the user smoked by using the cigarette 3 accommodated in the accommodating portion 10040. In other words, the cigarette 3 may be pulled out of the accommodating portion 10040 by holding and turning the cigarette accommodated in the accommodating portion 10040 by hand.
After the cigarette 3 is separated from the accommodating portion 10040, the user may remove the accommodating portion 10040 from the aerosol generating apparatus for a cleaning operation.
When the accommodating portion 10040 is separated from the aerosol generating apparatus, the accommodating path 10040h is exposed through the discharging hole 10040a as shown in
