This application is a National Stage of International Application No. PCT/KR2018/004181 filed Apr. 10, 2018, claiming priority based on Korean Patent Application No. 10-2017-0046938 filed Apr. 11, 2017, Korean Patent Application No. 10-2017-0077586 filed Jun. 19, 2017, and Korean Patent Application No. 10-2017-0128293 filed Sep. 29, 2017.
Embodiments relate to an aerosol generating device provided with a rotary heater, and more particularly, to an aerosol generating device in which a heater rotates before a cigarette is separated to conveniently separate the cigarette and the heater and discharge a residue to the outside of the aerosol generating device along with the cigarette.
Recently, the demand for a method of generating aerosol by heating an aerosol generating material in a cigarette has increased, and thus, research into a heated cigarette or a heated aerosol generating device has been actively conducted.
When an aerosol generating device provided with a heater that heats a cigarette by using electricity is used, the cigarette that generates a smoking gas by being heated by the heater may be separated from the aerosol generating device and may be discarded, and then a new cigarette may be inserted into the aerosol generating device.
Korean Patent Registration No. 10-1667124 relates to an aerosol generating device that generates a smoking gas by heating a cigarette, and describes a structure of a holder that assists an operation of inserting the cigarette into the aerosol generating device or an operation of separating the cigarette from the aerosol generating device.
When a user uses an aerosol generating device having such a structure, the user inserts a cigarette into a holder extracted from the aerosol generating device to the outside and pushes the holder and the cigarette into the aerosol generating device for smoking, and after smoking, pulls the holder out of the aerosol generating device and then removes the cigarette from the holder.
In the aerosol generating device including the holder configured as above, because the holder simply guides an operation of inserting and separating the cigarette into and from the holder, a residue generated from the cigarette heated during smoking remains on elements such as the heater and an internal space of the aerosol generating device, thereby making it difficult to keep the aerosol generating device clean.
When the user separates the cigarette from the aerosol generating device, the user holds the cigarette inserted into the holder in his/her hand and pulls the cigarette out of the holder to remove the cigarette from the aerosol generating device, and in this case, a tobacco component attached to contact surfaces of the cigarette and the heater is not separated and remains on the heater even during separation of the cigarette by the user. The tobacco component generated from the cigarette is attached to the contact surfaces between the cigarette and the heater, and because the tobacco component attached to the heater is condensed due to heat of the heater to further increase an adhesive force, a degree of cleanliness of the internal space of the aerosol generating device and the heater decreases as the time during which the aerosol generating device is used increases.
Embodiments provide an aerosol generating method and device. Also, embodiments provide a computer-readable recording medium having embodied thereon a program for executing the aerosol generating method in a computer.
Also, embodiments provide an aerosol generating device for conveniently separating a cigarette.
Also, embodiments provide an aerosol generating device for removing a material attached to a heater.
Technical problems to be solved by embodiments are not limited to the above-described technical problems and there may be other technical problems.
Embodiments may implement an aerosol generating device provided with a rotary heater.
An aerosol generating device provided with a rotary heater according to an embodiment includes: a casing having a hollow shape and comprising a path in which a cigarette is accommodated; a rotating member rotatably coupled to the casing; and a heater that has an end portion located inside the path to be inserted into the cigarette accommodated in the path, is connected to the rotating member to rotate along with the rotating member, and heats the cigarette when electricity is applied to the heater.
The rotating member may be coupled to the casing to rotate about a central axis in a longitudinal direction of the path.
The heater may rotate about the central axis in the longitudinal direction of the path.
The aerosol generating device may further include a connector connecting the rotating member to the heater and rotating along with the rotating member and the heater.
The aerosol generating device may further include a protruding portion protruding from any one of the connector and the rotating member, and a groove portion formed in the other of the connector and the rotating member so that the protruding portion is inserted into the groove portion, wherein the casing further comprises an intermediate container having a guide hole allowing the protruding portion to pass therethrough and extending in a circumferential direction about a center of rotation of the rotating member to provide a movement path for the protruding portion while the rotating member rotates.
The intermediate container may further include a rotation limiter configured to limit movement of the protruding portion.
The connector may have a through-hole through which the end portion of the heater passes, and may include a coupling protrusion protruding from one of the heater and the through-hole and a coupling groove formed in the other of the heater and the through-hole so that the coupling protrusion is inserted into the coupling groove.
The aerosol generating device may further include a pressing member provided in a path in which the protruding portion moves and configured to apply an elastic force with respect to movement of the protruding portion.
The casing may further include an inner container having a hollow shape, comprising the path in which the cigarette is accommodated, and located inside the intermediate container, and an outer container having a hollow shape and located outside the intermediate container.
The aerosol generating device may further include a cap coupled to an end portion of the inner container and having a hole through which the end portion of the heater passes.
The aerosol generating device may further include a movement protrusion protruding from any one of the rotating member and the casing, and a guide groove portion formed in the other of the rotating member and the casing so that the movement protrusion is inserted into the guide groove portion and extending in a circumferential direction about center of rotation of the rotating member to guide movement of the protruding portion.

A cigarette inserted into a holder according to another embodiment includes: a tobacco rod including a plurality of tobacco strands; a first filter segment that is hollow; a cooling structure configured to cool generated aerosol; and a second filter segment.
In an aerosol generating device provided with a rotary heater according to the above embodiments, because a heater first rotates due to the rotation of a rotating member before a cigarette is separated and thus contact surfaces between the heater and the cigarette are separated, the cigarette and the heater may be conveniently separated.
Also, because the heater rotates and thus a state in which a residue is attached to the cigarette is maintained, the residue attached to the cigarette may be easily discharged to the outside of the aerosol generating device along with the cigarette.

Hereinafter, embodiments will be described in detail with reference to the drawings. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
The aerosol generating device provided with the rotary heater according to the embodiment of
The casing 10 forms the exterior of the aerosol generating device and accommodates and protects various elements in an internal space thereof. The casing 10 has a hollow cylindrical shape whose inside is empty, and has a front end portion open to the outside so that the cigarette 7 is inserted into the casing 10 through the front end portion.
The casing 10 may be formed of a plastic material having without electric conductivity and heat conductivity, or may be formed of a metal material having a surface coated with a plastic material. Although the casing 10 has a cylindrical shape having a circular cross-section in the embodiment, the embodiment is not limited by a configuration of the casing 10. For example, the casing 10 may have a polygonal cross-sectional shape such as a quadrangular cross-sectional shape.
The path 20 in which the cigarette 7 is accommodated is formed inside the casing 10. The cigarette 7 may have a cylindrical shape, and the path 20 has an inner diameter corresponding to an outer diameter of the cigarette 7.
Referring to
The inner container 12 includes the path 20 for accommodating the cigarette 7, a first opening 21 open at an end of the path 20 to the outside so that the cigarette 7 is inserted from the outside into the first opening 21, and a second opening 22 open at the other end of the path 20.
The path 20 formed in the inner container 12 has a cylindrical shape corresponding to a shape of the cigarette 7. The embodiment is not limited by a shape of the path 20, and, for example, the path 20 may be formed to have a polygonal cross-sectional shape such as a quadrangular cross-sectional shape.
The inner container 12 includes a flange 12p protruding from the outer surface of the inner container 12 and extending in a circumferential direction about a central axis of the inner container 12, and a coupling protrusion 12c protruding outward from the flange 12p.
A cap 14 having a hole 29 through which a first end portion 31 of the heater 30 passes is coupled to the second opening 22 of the inner container 12. The cap 14 includes a coupling groove 14c with which the coupling protrusion 12c of the inner container 12 is coupled. When the cap 14 is coupled to the inner container 12 to cover the second opening 22 of the inner container 12, the coupling protrusion 12c of the inner container 12 is coupled with the coupling groove 14c of the cap 14 and thus the cap 14 is fixed to the inner container 12.
The embodiment is not limited by a configuration in which the cap 14 and the inner container 12 are independent elements, and, for example, the cap 14 and the inner container 12 may be integrally formed as one element.
The cap 14 contacts an end portion of the cigarette 7 accommodated in the path 20. When a user of the aerosol generating device moves the cigarette 7 along the path 20 by inserting the cigarette 7 into the path 20 and the end portion of the cigarette 7 reaches the cap 14, a sense of touch that the end portion of the cigarette 7 contacts the cap 14 may be transmitted to the user's hand holding the cigarette 7. Accordingly, the user may conveniently mount the cigarette 7 onto the aerosol generating device by a simple action of holding the cigarette 7 in his/her hand and pushing the cigarette 7 into the first opening 21 of the path 20.
The inner container 12 is an innermost container of the casing 10, and provides a movement path of the cigarette 7 so that the cigarette 7 inserted from the outside moves along the path 20 and accommodates the cigarette 7 therein. After the inner container 12, the intermediate container 11, and the outer container 13 are coupled to one another, while the aerosol generating device is used, the inner container 12 does not move relative to the intermediate container 11 and the outer container 13 and is maintained at a fixed position.
The heater 30 for heating the cigarette 7 is provided in the casing 10. The heater 30 is fabricated to have a pin shape or a rod shape and the first end portion 31 of the heater 30 is located inside the path 20 through the hole 29 of the cap 14, and, when the cigarette 7 is accommodated in the casing 10, the first end portion 31 of the heater 30 is inserted into the end portion of the cigarette 7.
A size of the hole 29 formed in the cap 14 may correspond to a thickness of the first end portion 31 of the heater 30. For example, when the first end portion 31 of the heater 30 has a circular cross-sectional shape, the hole 29 has a circular cross-sectional shape, and an inner diameter of the hole 29 corresponds to an outer diameter of the first end portion 31 of the heater 30.
The embodiment is not limited by a size of the inner diameter of the hole 29, and, for example, the inner diameter of the hole 29 may be greater than the outer diameter of the first end portion 31 of the heater 30 and an inner surface of the hole 29 may be spaced apart from an outer surface of the first end portion 31 of the heater 30.
A second end portion 32 of the heater 30 that is opposite to the first end portion 31 is electrically connected to an electricity supplying device 72 located at a rear portion of the casing 10 through an electrical wiring 71. A base 19 surrounding the electricity supplying device 72 is connected to the rear portion of the casing 10. The base 19 may rotatably support the rotating member 40 so that the rotating member 40 may rotate along with the casing 10.
When electricity of the electricity supplying device 72 is supplied to the heater 30 in a state where the cigarette 7 is inserted into the first end portion 31 of the heater 30, the heater 30 is heated and the cigarette 7 is heated accordingly.
The rotating member 40 is exposed to an outside of the casing 10 and rotatably coupled to the casing 10 to rotate about a central axis O in a longitudinal direction of the path 20. When the user holds the rotating member 40 in his/her hand and rotates the rotating member 40, the rotating member 40 rotates about the central axis O, and the heater 30 also rotates about the central axis O along with the rotating member 40.
The rotating member 40 may be formed of a material having low electrical conductivity and low heat conductivity. For example, the rotating member 40 may be formed of a material such as rubber or plastic, or may be formed of a metal material and then an outer surface of the rotating member 40 which is touched by the user's hands may be coated with a material without heat conductivity and electrical conductivity.
The rotating member 40 may be coupled to an outer surface of the casing 10, and may rotate relative to the casing 10. The rotating member 40 has a hollow cylindrical shape whose inside is empty. The rotating member 40 includes a groove portion 41 having a concave shape and formed in an inner surface of the rotating member 40.
A connector 50 is coupled to the inside of the rotating member 40. The connector 50 has a substantially circular plate shape. Because the connector 50 connects the rotating member 40 and the heater 30, the connector 50 may rotate along with the rotating member 40 and the heater 30. The connector 50 includes a protruding portion 51 that protrudes outward. When the connector 50 is located inside the rotating member 40, the protruding portion 51 of the connector 50 is inserted into the groove portion 41 of the rotating member 40, thereby limiting the rotation of the connector 50 relative to the rotating member 40.
The embodiment is not limited by a shape of the connector 50, and, for example, the connector 50 may have a cylindrical shape or a rod shape.
Although a configuration in which the protruding portion 51 is formed on the connector 50 and the groove portion 41 is formed in the rotating member 40 is described in the embodiment, the embodiment is not limited by the configuration, and, for example, a groove portion may be formed in the connector 50 and a protruding portion may be formed on the rotating member 40. Also, the connector 50 and the rotating member 40 may be coupled to each other by using an adhesive, facing screw surfaces, or fastening means such as screws, instead of using a groove portion and a protruding portion.
The protruding portion 51 of the connector 50 is inserted through a guide hole 11p of the intermediate container 11 into the groove portion 41 of the rotating member 40. The guide hole 11p is formed by extending by a pre-determined angle in a circumferential direction about a central axis of the intermediate container 11, that is, the circumferential direction about the center of rotation of the rotating member 40. The intermediate container 11 includes a rotation limiter 11e formed at an end of the guide hole 11p.
The connector 50 has a through-hole 52 through which the first end portion 31 of the heater 30 passes. Also, a coupling groove 53 having a concave shape is formed in an inner wall of the through-hole 52 of the connector 50. A coupling protrusion 33 protruding to have a shape corresponding to the coupling groove 53 is formed on an outer surface of the heater 30.
When the first end portion 31 of the heater 30 passes through the through-hole 52 of the connector 50, the coupling protrusion 33 protruding from the outer surface of the heater 30 is inserted into the coupling groove 53 of the connector 50, and thus the heater 30 is coupled to the connector 50 and the connector 50 and the heater 30 form one body rotating together.
Although only a configuration in which the coupling protrusion 33 is formed on the heater 30 and the coupling groove 53 is formed in the connector 50 is described in the illustrated embodiment, the embodiment is not limited by the configuration, and for example, a coupling groove may be formed in the heater 30 and a coupling protrusion may be formed on the connector 50. Also, the heater 30 and the connector 50 may be coupled to each other by using an adhesive, facing screw surfaces, or fastening means such as screws, instead of using a coupling protrusion and a coupling groove.
As the rotating member 40 rotates, the connector 50 and the heater 30 connected to the rotating member 40 rotate along with the rotating member 40. Because the protruding portion 51 of the connector 50 may rotate along the guide hole 11p of the intermediate container 11, the connector 50, the rotating member 40, and the heater 30 may rotate together within a range where the protruding portion 51 may move along the guide hole 11p.
When the rotating member 40 rotates clockwise in a state of
In the aerosol generating device according to the embodiment of
After using the aerosol generating device, the user has to remove the cigarette 7 from the aerosol generating device. When the user rotates the rotating member 40 before the cigarette 7 is removed from the aerosol generating device of
A tobacco material (or a residue) generated from the cigarette 7 while the cigarette 7 is heated by the heater 30 may be condensed and trapped in contact surfaces between the heater 30 and the cigarette 7. When the heater 30 rotates in a state where the first end portion 31 of the heater 30 is inserted into the cigarette 7 as shown in
When the heater 30 rotates and thus the contact surfaces between the heater 30 and the cigarette 7 are separated from each other, the user may hold the cigarette 7 and may pull the cigarette 7 out of the path 20 of the casing 10, to completely separate the cigarette 7 from the casing 10 of the aerosol generating device.
In a conventional aerosol generating device, because a user separates a cigarette from the conventional aerosol generating device by simply pulling the cigarette from the conventional aerosol generating device, a tobacco material present between the cigarette and a heater is trapped in the heater in many cases.
However, in the aerosol generating device according to the embodiment, before the cigarette 7 is separated from the aerosol generating device, the heater 30 is rotated by rotating the rotating member 40 in a state where the cigarette 7 is maintained at a fixed position with respect to the casing 10.
Because the cigarette 7 is maintained in a fixed state with respect to the casing 10 while the heater 30 rotates and a position of the cigarette 7 with respect to the casing 10 is not changed, the contact surfaces between the cigarette 7 and the heater 30 attached to each other due to the tobacco material may be easily separated. Also, in this process, a state where the residue present between the cigarette 7 and the heater 30 is transferred to the cigarette 7 is maintained.
Because the heater 30 and the cigarette 7 are first separated from each other through the above operation, and then the user may hold the cigarette 7 and may separate the cigarette 7 from the aerosol generating device, the residue transferred to the cigarette 7 may be easily discharged to the outside of the aerosol generating device along with the cigarette 7.
The aerosol generating device according to the embodiment of
The embodiment is not limited by a configuration of the pressing member 70, and, for example, an elastic pressing member may include a compression cylinder using a liquid or a gas.
The aerosol generating device provided with a rotary heater according to the embodiment of
The casing 110 may have a hollow cylindrical shape, and the casing 110 includes the path 20 having an inner diameter corresponding to an outer diameter of the cigarette 7 and accommodating the cigarette 7. The path 20 has the first opening 21 open at an end of the path 20 to the outside and a bottom portion 22d supporting a lower end portion of the cigarette 7 accommodated in the path 20.
The casing 110 has the hole 29 connected to the path 20 so that the first end portion 31 of the heater 30 passes through the hole 29. The hole 29 is formed to pass through a central area of the bottom portion 22d of the path 20.
The heater 30 that heats the cigarette 7 is provided in the casing 110. The first end portion 31 of the heater 30 is located inside the path 20 through the hole 29, and, when the cigarette 7 is accommodated in the casing 10, the first end portion 31 of the heater 30 is inserted into an end portion of the cigarette 7.
The second end portion 32 of the heater 30 is electrically connected to the electricity supplying device 72 located at a rear portion of the casing 110 through the electrical wiring 71. A base 119 surrounding the electricity supplying device 72 is connected to the rear portion of the casing 110. The base 119 may rotatably support the rotating member 140 so that the rotating member 140 may rotate along with the casing 110.
When electricity of the electricity supplying device 72 is supplied to the heater 30 in a state where the cigarette 7 is inserted into the first end portion 31 of the heater 30, the cigarette 7 is heated.
The rotating member 140 is rotatably coupled to the casing 110 to rotate about the central axis O in a longitudinal direction of the path 20. When the user holds the rotating member 140 in his/her hand and rotates the rotating member 140, the rotating member 140 rotates about the central axis O, and the heater 30 also rotates about the central axis O along with the rotating member 140.
The rotating member 140 is rotatably coupled to the casing 110. The rotating member 140 has a hollow cylindrical shape whose inside is empty.
The rotating member 140 has a through-hole 142 through which the first end portion 31 of the heater 30 passes. Also, the rotating member 140 includes a groove portion 141 formed in an inner surface of the rotating member 140. The heater 30 includes a protruding portion 133 having a shape corresponding to the groove portion 141 of the rotating member 140 and protruding outward from an outer surface of the heater 30.
When the first end portion 31 of the heater 30 passes through the through-hole 142 of the rotating member 140, the protruding portion 133 protruding from the outer surface of the heater 30 is inserted into the groove portion 141 of the rotating member 140, and thus the heater 30 is coupled to the rotating member 140 and the rotating member 140 and the heater 30 form one body rotating together.
Although only a configuration in which the protruding portion 133 is formed on the heater 30 and the groove portion 141 is formed in the rotating member 140 is described in the embodiment, the embodiment is not limited by the configuration, and, for example, a groove portion may be formed in the heater 30 and a protruding portion may be formed on the rotating member 140.
A movement protrusion 147 is formed on a surface of the rotating member 140 facing the casing 110. A guide groove portion 117 into which the movement protrusion 147 may be inserted is formed in a surface of the casing 110 facing the rotating member 140. The guide groove portion 117 is formed to extend by a pre-determined distance in a circumferential direction about the center of rotation of the rotating member 140.
The base 119 includes a flange 148 protruding toward the rotating member 140. The flange 148 extends in the circumferential direction about the central axis O that is the center of rotation of the rotating member 140. The flange 148 protrudes from the base 119 coupled to the rear portion of the casing 110 and passes through a connection path 140s extending in the circumferential direction of the rotating member 140 to be coupled to a flange groove 118 of the casing 110. Accordingly, the rotating member 140 is rotatably supported about the central axis O by the flange 148 between the casing 110 and the base 119.
While the rotating member 140 rotates relative to the casing 110, the movement protrusion 147 of the rotating member 140 moves along the guide groove portion 117 in a state where the movement protrusion 147 is inserted into the guide groove portion 117 of the casing 110. When the movement protrusion 147 reaches an end portion of the guide groove portion 117, the end portion of the guide groove portion 117 limits further movement of the movement protrusion 147, thereby limiting the rotation of the rotating member 140.
As the rotating member 140 rotates, the heater 30 connected to the rotating member 140 rotates along with the rotating member 140. Because the movement protrusion 147 of the rotating member 140 may rotate along the guide groove portion 117 of the casing 110, the rotating member 140 and the heater 30 may rotate together within a range where the movement protrusion 147 may move along the guide groove portion 117.
When a user rotates the rotating member 140 before the cigarette 7 is removed from the aerosol generating device according to the embodiment of
When the heater 30 rotates in a state where the first end portion 31 of the heater 30 is inserted into the cigarette 7, contact surfaces between the cigarette 7 and the heater 30 which are attached to each other due to a tobacco material trapped in the contact surfaces between the cigarette 7 and the heater 30 may be easily separated from each other.
When the heater 30 rotates and thus the contact surfaces between the heater 30 and the cigarette 7 are separated from each other, the user may hold the cigarette 7 and pull the cigarette 7 out of the path 20 of the casing 110, to completely separate the cigarette 7 from the casing 110 of the aerosol generating device.
Because the heater 30 is first separated from the cigarette 7 through the above operation, and then the user may hold the cigarette 7 and may separate the cigarette 7 from the aerosol generating device, a residue transferred to the cigarette 7 may be easily discharged to the outside of the aerosol generating device along with the cigarette 7.

Reference numerals denoting elements in
Referring to
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 10C and the discharging rate (C-rate) may be 16C to 20C. 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. For example, the heater 130 may have a diameter of 2 mm, a length of 23 mm, and a cylindrical shape. Also, end 131 of heater 130 may be processed to have an acute angle edge. But, the embodiments are not limited to these features. 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, if the heater 130 has a length of 23 mm, only a part of the heater 130, 12 mm distanced from the end 131, is heated, while other part of the heater 130 is not heated.
The heater 130 may be an electrical resistive heater. For example, the heater 130 includes an electrically conductive track, and the heater 130 may be heated as 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.
The holder 1 may have a special temperature sensor. Alternatively, the holder 1 may not be provided with a temperature sensing sensor, and the heater 130 may serve as a temperature sensing sensor. For example, the heater 130 may further include a second electrically conductive track for sensing temperature in addition to a first electrically conductive track for sensing heating temperature.
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 includes 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 serves 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.
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 conventional pressure sensor, and cigarette insertion detecting sensor may be implemented by a general capacitance sensor or electric resistive 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.
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.
The examples of type of battery 210 may be the same as the battery 110 shown in
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 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.
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.
As above explained along with
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. In
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, if it is determined that the holder 2 is fully inserted into the cradle 2 through the terminals 170, 260 and/or the attaching members 271 and 272, the control unit 220 may charge the battery 110 of the holder 1 using electrical power of the battery 210.
If the holder 1 is fully tilted inside the cradle 2 as shown in
If the holder 1 is tilted as shown in
Also, even in the state that the holder 1 is tilted, the terminal 170 of the holder and the terminal 260 of the cradle 2 are coupled to 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.
A method for generating aerosols shown in
In operation 810, 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 820. When the holder 1 is separated from the cradle 2, the method proceeds to operation 830.
In operation 820, 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 820, 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 840. When the holder 1 is not tilted (i.e., the holder 1 is completely inserted into the cradle 2), the method proceeds to operation 870.
In operation 830, 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 840. Otherwise, the method is terminated.
In operation 840, 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 850, 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 860, 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 870, 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 910, 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.
In operation 920, 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 and the temperature of the heater 130, as described above with reference to
In operation 930, the control unit 120 or 220 determines whether the number of puffs of the user is 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.
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 950. When the number of puffs of the user is less than the puff limit number, the method proceeds to operation 940.
In operation 940, 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 950. When the operation time of the holder 1 is less than the operation limit time, the method proceeds to operation 920.
In operation 950, 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.
The flowchart shown in
Although not shown in
In operation 1010, 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 1020. When the button 240 is not pressed, the method proceeds to operation 1030.
In operation 1020, 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 1030, 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 1040. Otherwise, the method is terminated.
In operation 1040, 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 mixed with the outside air and is delivered to a user's mouth. As shown in
Referring to
Meanwhile, referring to
But, the features of 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. The tobacco rod 310 may have a length ranged between 7 mm to 15 mm, preferably about 12 mm. Also, the tobacco rod 310 may have a diameter ranged between 7 mm to 9 mm, preferably about 7.9 mm. The length and diameter of tobacco rod 310 are not limited to the above range.
Also, the tobacco rod 310 may include other additive materials like a flavoring agent, a wetting agent, and/or acetate compound. 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. One tobacco strand may be formed into a cuboid shape with 1 mm width, 12 mm depth, and 0.1 mm height, but not limited thereto.
The tobacco rod 310 filled with tobacco strands may generate much more aerosol than tobacco rod 310 filled with tobacco sheet. By filling the tobacco rod with tobacco strands, wider surface area can be secured compared to using tobacco sheet. 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, the tobacco rod can generate much more aerosol compared to when being filled with tobacco sheet.
Also, when the cigarette 3 is being disengaged from the holder 1, the tobacco rod 310 filled with tobacco strands can be easily pulled out compared to when being filled with tobacco sheet. Compared to tobacco sheet, the tobacco strands experience weaker friction when in contact with the heater 130. Therefore, when the tobacco rod 310 is filled with tobacco strands, the tobacco rod can be more easily removed from the holder 1 compared to when being filled with tobacco sheet.
The tobacco sheet can be formed by pulverizing raw tobacco material into a slurry and drying the slurry. For example, the slurry may contain 15% to 30% aerosol generating material. 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 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 7 mm to 15 mm, preferably about 7 mm, but is not limited thereto. The length of the first filter segment 321 may be smaller than about 7 mm, but the first filter segment preferably should have enough length so that function of at least one of components (such as, cooling element, capsule, acetate filter) may not be damaged. The length of the first filter segment 321 is not limited to the above ranges. Meanwhile, the length of the first filter segment 321 may extended so that whole length of the cigarette 3 can be adjusted based on the length of the first filter segment 321.
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 with a hollow cavity, but is not limited thereto. The length of the second filter segment 323 may be within the range from 5 mm to 15 mm, preferably about 12 mm. The length of the second filter segment 323 is not limited to above range.
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 capsule 324 may have a diameter equal to or greater than 2 mm, preferably ranged between 2-4 mm.
A material forming a surface of the capsule 324 may be starch and/or gellant. For example, the gallant may include gelatin, or a gum. Also, a gelling agent may be further used as a material for forming the film of the capsule 324. Here, gelling agent may include, for example, a calcium chloride. 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 length of the cooling structure 322 may be ranged between about 10 mm to 20 mm, preferably about 14 mm. The length of the cooling structure 322 is not limited to the above range.
For example, the cooling structure 322 may be formed by polylactic acid. The cooling structure 322 may be fabricated into various shapes in order to increase a surface area per unit area, namely, a surface area contacting with aerosol. Hereinafter, Various examples of the cooling structure 322 will be explained referring to
The tobacco rod 310 and the first filter segment 321 are packed by a first wrapper 331. For example, the first wrapper 331 may be made of an oil-resistant paper sheet.
The cooling structure 322 and the second filter segment 323 are packed by a second wrapper 332. Also, a whole part of cigarette 3 is packaged again by a third wrapper 333. For example, the second wrapper 332 and the third wrapper 333 may be fabricated using a general filter wrapping paper. Alternatively, the second wrapper 332 may be a hard wrapping paper or PLA scented paper. Also, the second wrapper 332 may package a part of the second filter segment 323, and additionally package other part of the second filter segment 323 and the cooling structure 322.
Referring to
The fourth wrapper 334 may be formed by depositing or coating a predetermined material on one surface or both surfaces of wrapping paper. Here, an example of the predetermined material may be, but is not limited to, silicon. 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 fourth wrapper 334.
Meanwhile, although
The fourth wrapper 334 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 fourth wrapper 334 includes a non-combustible material, the burning of the cigarette 3 may be prevented.
Furthermore, the fourth wrapper 334 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 fourth wrapper 334 wraps 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.
For example, the cooling structure of any of
For example, when the cooling structure is manufactured by charging a film (sheet), the film (sheet) may be crushed by an external impact. In this case, an aerosol cooling effect of the cooling structure is reduced.
Alternatively, when the cooling structure is manufactured by using extrusion molding or the like, process efficiency is reduced due to the addition of processes such as cutting of a structure. Also, there are limitations in manufacturing the cooling structure in various shapes.
As the cooling structure according to an embodiment is manufactured by using polylactic acid fibers (e.g., weaving), the risk that the cooling structure is deformed or loses its function by an external impact may be reduced. Also, the cooling structure having various shapes may be manufactured by changing a method of combining fibers.
Also, when the cooling structure is manufactured by using fibers, a surface area contacting aerosol is increased. Accordingly, an aerosol cooling effect of the cooling structure may be further improved.

The first cross-section 1351 may border on the first filter segment 321, and may include a gap through which aerosol is introduced. The second cross-section 1352 may border on the second filter segment 323, and may include a gap through which the aerosol may be discharged. For example, although each of the first cross-section 1351 and the second cross-section 1352 may include a single gap having the same diameter, diameters and numbers of gaps included in the first cross-section 1351 and the second cross-section 1352 are not limited thereto.
In addition, the cooling structure 1350 may include a third cross-section 1353 including a plurality of gaps between the first cross-section 1351 and the second cross-section 1352. For example, diameters of the plurality of gaps included in the third cross-section 1353 may be less than diameters of the gaps included in the first cross-section 1351 and the second cross-section 1352. Also, the number of the gaps included in the third cross-section 1353 may be greater than the number of the gaps included in the first cross-section 1351 and the second cross-section 1352.
Referring to
As described above, a holder may generate aerosol may 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. In particular, when the holder is tilted, a heater may be heated by power of a battery of the cradle.
