The present application claims priority to Korean Patent Application No. 10-2023-0102916, filed Aug. 7, 2023, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure relates to an aerosol-generating device and an aerosol-generating system. In particular, the present disclosure relates to an aerosol-generating device and an aerosol-generating system operable in various modes to provide various smoking tastes, flavors, and the like.
Although tobacco typically refers to a perennial plant belonging to the Solanaceae family of the dicotyledonous plant order, the term has recently come to encompass tobacco products manufactured for smoking and composed of tobacco leaves wrapped in cigarette paper and a filter part placed on one end. There are thousands of types of tobacco products worldwide, which have come out in a variety of shapes and forms.
Ingredients and manufacturing processes determine the smoking tastes, stimulation, and the like of tobacco. However, tobacco products using auxiliary devices have recently been developed to overcome this shortcoming and improve various smoking tastes and flavors. In addition, with positive user feedback, demand for such auxiliary devices is growing.
An auxiliary device is typically used in a manner to form and supply aerosols by holding a dedicated tobacco, heating the tobacco, and then heating a liquid stored therein. Smoking with the use of such an auxiliary device enables a sufficient amount of aerosols to be artificially supplied even when heating the dedicated tobacco to low temperatures and thus is likely to be more satisfying for users.
However, problems have been recently raised about tobacco products using auxiliary devices, so there have been growing calls for improvements.
First, one problem is that a liquid is essential.
Tobaccos are heated to low temperatures when using an auxiliary device. Thus, to supply substances to a user, aerosols capable of moving these substances are essential, meaning that a liquid is essentially required to generate aerosols. For this reason, there has been a disadvantage in that these substances cannot be supplied to a user by auxiliary device operation when the liquid is insufficient. In particular, the problem that the device cannot be operable without the liquid during hours when the liquid is unavailable, such as early morning and late evening, has been raised.
Second, another problem is that smoking tastes and flavors are limited.
One of the reasons for using an auxiliary device is to provide a variety of smoking tastes, flavors, and the like. However, the auxiliary device is heated to a predetermined temperature and provides aerosols, so there is a limitation in providing only limited smoking tastes, flavors, and the like.
The present disclosure, according to one embodiment, aims to provide an aerosol-generating device and an aerosol-generating system operable in various modes to solve the problems described above.
In other words, the present disclosure, according to one embodiment, aims to provide an aerosol-generating device and an aerosol-generating system operable to enable tobacco substances to reach a user even in the case where a liquid is insufficient.
In addition, the present disclosure, according to one embodiment, aims to provide an aerosol-generating device and an aerosol-generating system having a wide range of heating temperatures, enabling users to enjoy various smoking tastes and flavors by heating tobacco to various temperatures.
According to one embodiment, an aerosol-generating device includes a housing, an inlet hole formed on one side of the housing, the inlet hole through which an aerosol-generating article enters, a liquid storage part placed to be close to the inlet hole and configured to store a liquid, and a heating part configured to heat the liquid storage part and the inlet hole such that the aerosol-generating article is combusted, wherein the heating part may heat the inlet hole or both the liquid storage part and the inlet hole.
The heating part includes a first heater configured to heat the liquid storage part and a second heater configured to heat the inlet hole, when both the first and second heaters are enabled to operate, the second heater is enabled to be heated to a first temperature, and when the second heater is enabled to operate, the second heater is enabled to be heated to a second temperature higher than the first temperature.
The first temperature is 120 degrees or higher, and the second temperature is higher than the first temperature by at least 40 degrees or more.
The first temperature is in a range of 120 to 200 degrees, and the second temperature is in a range of 160 to 280 degrees.
When an amount of the liquid in the liquid storage part is smaller than a preset amount, the second heater is heated.
In the housing, a detection sensor configured to detect the aerosol-generating article entering through the inlet hole is placed, and when the detection sensor detects the preset aerosol-generating article, the second heater is heated.
An aerosol-generating system includes a housing, an inlet hole formed on one side of the housing, a liquid storage part installed in the housing, the liquid storage part configured to store a liquid to be converted into an aerosol when heated, a heating part configured to heat only the inlet hole or both the liquid storage part and the inlet hole and an aerosol-generating article entering through the inlet hole, the aerosol-generating article comprising a medium part filled with 10% or more of a moisturizer and placed in a position corresponding to a portion heated by the heating part.
The aerosol-generating article includes a cooling part formed on one side of the medium part and having a plurality of perforated holes.
The cooling part comprises a plurality of segments placed in succession, the segments being hollow and having the plurality of perforated holes extending through an interior and an exterior thereof.
The aerosol-generating system may further include a detection sensor configured to detect the aerosol-generating article entering through the inlet hole, When the detection sensor detects the aerosol-generating article includes the cooling part, the heating part is enabled to operate such that only the inlet hole is heated.
The heating part of the aerosol-generating system includes a first heater configured to heat the liquid storage part and a second heater configured to heat the inlet hole, when both the first and second heaters are enabled to operate, the second heater is enabled to be heated to a first temperature, and when the second heater is enabled to operate, the second heater is enabled to be heated to a second temperature higher than the first temperature.
The second temperature is in a range of 160 to 280 degrees, and air enters the cooling part through the perforated holes, so the aerosol generated in the medium part is mixed with the air, diluted by 10% or more, and cooled.
The present disclosure, according to one embodiment, enables an aerosol-generating device to operate in various modes through a dual mode and a single mode, thereby generating and supplying an aerosol.
The present disclosure, according to one embodiment, enables single-mode operation when a liquid is insufficient and thus can supply an aerosol and substances to a user without involving the liquid, so the user can enjoy smoking tastes and flavors of tobacco even when the liquid is insufficient.
In addition, the present disclosure, according to one embodiment, enables an aerosol to be generated through various temperature changes based on a dual mode, a single mode, and the like, so the user can be provided with a variety of smoking tastes and flavors.
Hereinafter, embodiments of the present disclosure will be described in detail through exemplary drawings. However, these embodiments are not intended to limit the scope of the present disclosure.
In terms of adding reference numerals to components in each drawing, it should be noted that like reference numerals are used to identify like elements even when displayed in different drawings. In addition, when it is determined that a detailed description of a related known configuration or function may obscure the gist of the present disclosure, the detailed description thereof will be omitted.
In addition, the shape and size of the elements illustrated in the drawings may be exaggeratedly drawn for clarity and convenience of understanding the description. In addition, the terms particularly defined in consideration of functions and operations of the present disclosure are only for describing embodiments of the present disclosure and do not limit the scope of the present disclosure.
Hereinafter, an aerosol-generating device, according to a first embodiment of the present disclosure, will be described.
Referring to
The housing 110 is a device configured to form the exterior of the aerosol-generating device 100 of the present disclosure, and a variety of electronic devices and articles may be placed and stored therein. Each configuration described above may be fixedly placed in the housing 110, and an aerosol-generating article 200 (see
The battery 120 may be placed on one side of an internal space of the housing 110. The battery 120 is configured to store power and may apply power as needed. The battery 120 is connected to the heating part 140 and the control part 160, so depending on a control signal from the control part 160, the battery 120 may apply power to the second heater 145 or the first heater 141 and the second heater 145 constituting the heating part 140.
The liquid storage part 130 is placed in the housing 110. Despite not being illustrated in the drawing, the liquid storage part 130 may be separably coupled to the housing 110. The liquid storage part 130 may contain a liquid composition and a liquid transfer means. When the heating part 140 heats the liquid storage part 130, the liquid composition is heated, generating an aerosol.
The liquid composition may be a liquid containing tobacco-containing substances including volatile tobacco flavor components, or may be a liquid containing non-tobacco substances.
The liquid composition may include water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin complex. In this case, the fragrance may include menthol, peppermint, spearmint oil, a variety of fruit flavor ingredients, and the like, but is not limited thereto. In addition, the flavoring agent may include ingredients capable of providing various flavors or aromas to a user. The vitamin complex may be a mixture of at least one among vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. In addition, the liquid composition may include an aerosol-forming agent such as glycerin and propylene glycol.
In addition, the liquid transfer means (not illustrated) in the liquid storage part 130 may transfer the liquid composition in the liquid storage part 130 to the heating part 140 (first heater 141). For example, the liquid transfer means may be a wick, such as cotton fibers, ceramic fibers, glass fibers, or porous ceramics, but is not limited to. The liquid transfer means may be variously modified, but one example thereof may have a form in which a wick absorbing the liquid is placed in the liquid storage part 130 to bring one side thereof into contact with the heating part 140.
On the other, although the liquid storage part 130 and the inlet hole 150 are illustrated as not being in communication in the drawing, it is to be noted that such an illustration is for clarity of the description. In reality, the liquid storage part 130 and the inlet hole 150 may be in communication such that the aerosol generated in the liquid storage part 130 is supplied to the inlet hole 150.
The heating part 140 may enable the aerosol to be generated by receiving power from the battery 120 in the housing 110 and heating the aerosol-generating article 200 fixed to the liquid storage part 130 and the inlet hole 150. The heating part 140 may include the first heater 141 configured to heat the liquid storage part 130 and the second heater 145 configured to heat a medium part 210 of the aerosol-generating article 200 placed in the inlet hole 150.
When power is supplied, the first heater 141 heats the liquid storage part 130 to a set temperature, enabling the aerosol to be generated. The aerosol generated in the liquid storage part 130 may make up for insufficient aerosol when the aerosol-generating article 200 is heated to a low temperature, enabling the substances contained in the aerosol-generating article 200 to reach the user. In this case, the substances contained in the aerosol-generating article 200 include various substances such as nicotine, flavors, and aerosol-generating substances, which will be described in detail later when explaining the aerosol-generating article 200.
The first heater 141 may be a metal heating wire, a metal heating plate, a ceramic heater, and the like, but is not limited thereto. In addition, the first heater 141 may be composed of a conductive filament such as nichrome wire, and it is unproblematic even when being formed in a shape where the first heater 141 is wrapped around the liquid storage part 130.
The second heater 145 may heat the medium part 210 (see
For example, the second heater 145 may be formed in a shape where a susceptor is placed to face the inlet hole 150 while placing a coil to be wrapped around the susceptor, whereby the susceptor is heated when supplying power. In this case, the susceptor may include at least one among ferrite, a ferromagnetic alloy, stainless steel, and aluminum (Al).
In addition, the susceptor may include at least one among a ceramic such as graphite, molybdenum, silicon carbide, niobium, a nickel alloy, a metal film, zirconia, and the like, a transition metal such as (Ni), cobalt (Co), and the like, and a metalloid such as boron (B), phosphorus (P), and the like.
Furthermore, the second heater 145 of the present disclosure is not limited to the example mentioned above, and any means capable of heating the aerosol-generating article 200 may be modified to the extent (for example, a configuration such as a heater rod) that such a means does not cause difficulty in operation.
On the other hand, the second heater 145 may be heated to a first or second temperature depending on a mode (dual mode or single mode). The first temperature may be lower than the second temperature.
The first temperature, which is relatively lower than the second temperature, may be in a range of 120 to 200 degrees. More preferably, the first temperature is in a range of 120 to 190 degrees.
The second temperature is relatively higher than the first temperature, and the minimum temperature thereof may be 160 degrees, which is higher than 120 degrees, the minimum temperature of the first temperature, by 40 degrees or more. In other words, the second temperature may be in a range of 160 to 280 degrees. More preferably, the second temperature is in a range of 180 to 250 degrees.
The second heater 145 is heated to the first temperature when in the dual mode because the aerosol formed by the liquid storage part 130 assists the transition of the substances combusted in the aerosol-generating article 200. In other words, when the liquid storage part 130 is heated, the substances contained in the aerosol-generating article 200 may be transitioned to a smoker even when the aerosol-generating article 200 is heated to the first temperature.
On the contrary, in the case of the single mode where the liquid storage part 130 is not heated, the amount of the aerosol generated is reduced. As a result, the transition power of the article 200 is substances in the aerosol-generating significantly poor, making the substances contained in the aerosol-generating article 200 challenging to transition to a smoker.
Therefore, in the single mode where only the second heater 145 is heated, the aerosol-generating article 200 itself requires a high transition power, so the second heater 145 may heat the aerosol-generating article 200 to the second temperature, generating a large amount of the aerosol.
The inlet hole 150 may be formed on one side of the housing 110. Through the inlet hole 150, the aerosol-generating article 200 may be fixed by making contact with the inner surface of the housing 110. Therefore, the aerosol-generating article 200 may be heated and combusted by the second heater 145.
On the other hand, the control part 160, which will be described in detail below, may be omitted as needed. In other words, as described above or later, the control part 160 may be automatically controllable through calculation of various signals and information while the control part 160 is omitted. However, for convenience of description, it will be assumed that the control is enabled through the control part 160 in the present disclosure.
The control part 160 may enable the heating part 140 to operate differently by applying a control signal thereto depending on the preset dual or single mode.
When the control part 160 enables dual-mode operation through the control, the control part 160 may control both the first heater 141 and the second heater 145 to be heated. In the dual mode, the control part 160 may control the battery 120, the first heater 141, and the second heater 145 to be connected and may control the second heater 145 to be heated to a temperature corresponding to the dual mode. In this case, the first heater 141 may be heated to a preset temperature (for example, in a range of 200 to 250 degrees).
The second heater 145 may be heated to the first temperature in the dual-mode operation. In this case, the aerosol is generated in the liquid storage part 130 and moves through the inlet hole 150, and the article generated from the aerosol-generating article 200 may move along with the aerosol to be supplied to the user.
When the control part 160 enables single-mode operation through the control, the control part 160 may control only the second heater 145 to be heated. In this case, the control part 160 may control the battery 120 and the second heater 145 to be connected and may control the second heater 145 to be heated to the second temperature.
As described above, the present disclosure may provide a user with various flavors through different modes with a single device, enabling the users to be satisfied in many ways.
The control part 160 may automatically set the dual or single mode depending on the aerosol-generating article 200. To this end, the present disclosure may further include the detection sensor 170.
The detection sensor 170 is installed in the housing 110 to receive power from the battery 120 and may distinguish and recognize the aerosol-generating article 200 placed in the inlet hole 150. On the other hand, the detection of the aerosol-generating article 200 by the detection sensor 170 may mean that the type of aerosol-generating article 200 is distinguished and recognized.
For example, the detection sensor 170 may be a sensor Therefore, the aerosol-generating detecting capacitance. article 200 may be recognized by detecting changes in dielectric properties with the amount of moisture contained in the aerosol-generating article 200. In addition, the detection sensor 170 may operate in a manner to distinguish and recognize the aerosol-generating article 200 by detecting the shape, color, and the like of the image of the aerosol-generating article 200.
When the detection sensor 170 recognizes the aerosol-generating article 200 and transmits a recognition signal to the control part 160, the control part 160 may select and enable either dual-mode or single-mode operation.
For example, assuming that an A aerosol-generating article is suitable for the dual mode, and a B aerosol-generating article is suitable for the single mode, the control part 160 may control the battery 120 and the heating part 140 (temperature of the second heater 145) such that the dual-mode operation is enabled when the detection sensor 170 recognizes the A aerosol-generating article 200 and then transmits an A recognition signal to the control part 160, and such that the single-mode operation is enabled when the detection sensor 170 recognizes the B aerosol-generating article 200 and then transmits a B recognition signal to the control part 160.
Although the reason why the control part 160 operates in such a manner will be explained in detail later, this is to make a user enjoy the best flavor by taking into account the degree of filling the medium part 210 with the aerosol-generating substances relative to the aerosol-generating article 200 and the degree of cooling by a cooling part 220 (see
Hereinafter, an aerosol-generating device, according to a second embodiment of the present disclosure, will be described.
Unless otherwise described, the aerosol-generating device 100 in each embodiment described below is required to be understood to have a similar configuration to that of the aerosol-generating device 100 according to the first embodiment.
From a detailed description of the aerosol-generating device 100 according to the second embodiment referring to
The selector 180 may have any configuration, such as a wireless device controlled by a wireless terminal, a button, a switch, a touch screen, and the like. Accordingly, a user may enable an aerosol-generating article 200 to enter through an inlet hole 150 and operate the selector 180 such that a control part 160 enables either dual-mode or single-mode operation.
On the other hand, the aerosol-generating device 100, according to the second embodiment, may further include a warning part 190 in addition to the selector 180. The configuration of the warning part 190 may be unproblematic as long as this part is configured to issue a specific warning to a user by stimulating the five senses involving a light emitting a specific color, a screen, a speaker generating noise, or the like.
The warning part 190 is configured to issue a warning when a mode selected by a user through the selector 180 (either the dual mode or the single mode) is not suitable for the aerosol-generating article 200 entering through the aerosol-generating device 100 such that the user is aware of this situation. This is because depending on the substances with which the aerosol-generating article 200 is filled, the user may be unable to enjoy the flavor when the aerosol-generating device 100 operates in the selected mode.
For example, assuming that a user enables an aerosol-generating article suitable for the dual mode to enter through the inlet hole 150 and enables single-mode operation using the selector 180, the warning part 190 operates in this case, notifying the user that the aerosol-generating article having entered through the aerosol-generating device 100 is unsuitable for the single mode. Alternatively, the warning part 190 may stop the operation of the aerosol-generating device 100.
For example, when a user enables an aerosol-generating article suitable for the dual mode to enter through the inlet hole 150 and enables single-mode operation through the selector 180, the warning part 190 may control the aerosol-generating device 100 not to operate in the single mode. Thus, to enable the user to enjoy the flavors, there is no choice but to select the dual mode using the selector 180 when the aerosol-generating device 100 operates.
As described above, the warning part 190 may assist the selector 180 and enable the user to operate the aerosol-generating device 100 properly.
Hereinafter, an aerosol-generating device, according to a third embodiment of the present disclosure, will be described.
From a detailed description of the aerosol-generating device 100 according to the third embodiment referring to
The amount of the liquid stored in the liquid storage part 130 may be measured by a separate measurement sensor 165 configured to detect the liquid. However, even when the measurement sensor 165 is not involved, the control part 160 itself may detect the amount of the liquid. For example, the control part 160 may check the amount of the liquid in the liquid storage part 130 by checking the number of times power is applied to a first heater 141. In other words, the amount of the liquid reduced by a single operation of the first heater 141 may be pre-stored in the control part 160.
When the amount of the liquid in the liquid storage part 130 is detected to be smaller than a preset amount, the control part 160 may control the heating part 140 (second heater 145) such that the aerosol-generating device 100 operates in the single mode.
Therefore, a user may enjoy the flavors using the aerosol-generating device 100 even when there is no liquid in the liquid storage part 130.
Hereinafter, an aerosol-generating device, according to a fourth embodiment of the present disclosure, will be described.
Referring to
The timer 195 may measure the current time. The control part 160 may enable either single-mode or dual-mode operation depending on time. For example, the aerosol-generating device 100 of the present disclosure may enable the single mode to operate during a first time period and the dual mode to operate during a second time period. In this case, the first time period may range from 7:00 to 8:00 a.m., and the second time period may be a time other than the first time period.
Therefore, the present disclosure enables the operation without consuming the liquid during hours when the liquid is unavailable or moving around is difficult, such as early morning, improving user convenience. Furthermore, the first time period may include a plurality of time intervals (7:00 to 8:00 a.m., 10:00 to 11:00 p.m., and the like) rather than the time interval described above.
On the other hand, even in the case of the fourth embodiment, the selector 180 described above is included (see
Hereinafter, an aerosol-generating system, according to the first embodiment of the present disclosure, will be described.
The aerosol-generating system, according to the first embodiment, may include an aerosol-generating device 100 and an aerosol-generating article 200 of any one of the embodiments described with reference to
When the aerosol-generating device 100 of the present disclosure, according to the embodiment herein, operates in the single mode, only the second heater 145 is enabled to be heated to the second temperature and operate. In the case of an existing aerosol-generating device 100, a sufficient amount of atomization (amount of aerosol) fails to be generated even in single-mode operation, which may lead to a problem that the substances contained in the aerosol-generating article 200 fail to be delivered to the user. In addition, the aerosol-generating article 200 is heated to a relatively high temperature, so the user may feel unpleasant due to the high temperature.
The aerosol-generating article 200 that has solved such a problem, according to the embodiment illustrated in
The aerosol-generating article 200 of the present disclosure may include the medium part 210 and the cooling part 220.
When entering through the inlet hole 150 of the aerosol-generating device 100, the medium part 210 is placed in a position corresponding to the second heater 145. The medium part 210 may be heated by the second heater 145, generating the aerosol. In this case, the medium part 210 may be filled with at least 10% or more of an aerosol-generating moisturizer. Therefore, heating the medium part 210 of the aerosol-generating article 200 by the second heater 145 may enable the aerosol to be generated in a large amount, supplying nicotine and the like to the user.
More preferably, the aerosol-generating moisturizer accounts for 15% to 30%. In the most ideal example, the medium part 210 is filled with 15% of the aerosol-generating moisturizer.
In this case, the aerosol-generating moisturizer, for example, the aerosol-generating substances, may include at least one among aerosol-generating substances such as glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.
In addition, the medium part 210 may contain nicotine. The nicotine may occur naturally or be synthesized. For example, the nicotine may include one among freebase nicotine, a nicotine salt, or a combination thereof.
The nicotine salt may be formed by adding appropriate acids, including an organic or inorganic acid, to nicotine.
The acid to form the nicotine salt may be appropriately selected by taking into account the absorption rate of nicotine in the blood, heating temperature, flavors or tastes, solubility, and the like.
For example, the acid to form the nicotine salt may be an acid selected from the group consisting of benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, resorcinol, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid, and malic acid, or a mixture of two or more acids selected from the group described above. However, the acid to form the nicotine salt is not limited thereto.
On the other hand, the medium part 210 is preferably formed to have a horizontal length similar to that of the second heater 145, based on the cross section of the second heater 145. In other words, the medium part 210 and the second heater 145 may be formed to be similar in horizontal length. Therefore, the medium part 210 may be heated by receiving all the heat generated by the second heater 145.
For example, the medium part 210 may be manufactured into a cylindrical shape by folding a tobacco sheet to be wrinkled and may be formed by joining a plurality of tobacco strands with channels formed. In addition, a heat-conducting material may be wrapped around the medium part 210. In this case, the heat-conducting material may be a metal foil, aluminum, or similar materials.
The cooling part 220 is placed to be close to the medium part 210 and may enable the user to inhale the substances by reducing the temperature of the substances generated by the medium part 210. In other words, when the user applies suction force, the substances generated in the medium part 210 may pass through the cooling part 220 and then be delivered to the user.
As described above, when the aerosol-generating device 100 of the present disclosure operates in the single mode, the aerosol-generating article 200 is heated to the second temperature, which is much higher than the existing temperature heated. As a result, the user may feel unpleasant. The cooling part 220 may be formed to have an air dilution rate of about 10% or more. Preferably, the air dilution rate is in a range of about 15% to 30%, and the cooling part 220 is preferably formed to have an air dilution rate of 20% or more.
The cooling part 220 may be formed in a hollow shape. The cooling part 220, configured to cool the substances to be delivered to the user through the cooling part 220, may be a paper tube in a hollow cylindrical shape. The cooling part 220 may be made of a polymeric material or biodegradable polymeric material.
In addition, the cooling part 220 may have a plurality of perforated holes 230. Therefore, external air may enter the cooling part 220 through the perforated holes 230. Accordingly, the substances moving through the cooling part 220 may be diluted and cooled by the air entering through the perforated holes 230.
The medium part 210 and the cooling part 220 may be fixed in a form of being surrounded by an outer wrapper 240.
On the other hand, although a separate instruction number is not given, a filter part is placed next to the cooling part 220 to filter harmful substances while fixedly putting the device into the user's mouth.
Hereinafter, variations of the aerosol-generating article in the aerosol-generating system will be discussed.
From a detailed description of one variation of the aerosol-generating article referring to
The first cooling part 221 may be a hollow filter segment. Therefore, the substances may be cooled by the first cooling part 221 when moving through the hollow of the first cooling part 221. The second cooling part 222 may be formed to be hollow, and perforated holes 230 may be formed along the outer perimeter thereof. Therefore, the substances moving through the second cooling part 222 may be diluted and cooled by the air entering through the perforated holes 230.
The first cooling part 221 and the second cooling part 222 may be surrounded by an inner wrapper 250 and fixed and may be additionally surrounded by an outer wrapper 240 and fixed. In this case, the perforated holes 230 may be formed at a portion of the inner wrapper 250 corresponding to the second cooling part 222 and a portion of the outer wrapper 240 corresponding to the inner wrapper 250.
As described above, the aerosol-generating article 200 of the present disclosure may efficiently cool the substances through the first cooling part 221 and the second cooling part 222.
From a detailed description of another variation of the aerosol-generating article 200 referring to
For example, the first segment 225 may be formed in a hollow cylindrical shape, and the second segment 226 may be formed in a shape similar to that of the first segment 225. The first segment 225 and the second segment 226 are placed in succession to be close to each other and may be wrapped in the inner wrapper 250 and fixed.
Accordingly, the substances may move through the hollow of the first segment 225 and the second segment 226 and thus be cooled.
In addition, a plurality of perforated holes 230 may be formed in the first segment 225 and the second segment 226. The perforated holes 230 may not be closed by the inner wrapper 250, and a plurality thereof may be formed in the outer wrapper 240 surrounding the inner wrapper 250.
Therefore, when the user applies suction force, external air may penetrate the perforated holes 230 and enter the hollow through the first segment 225 and the second segment 226. As a result, the substances may be diluted by air and cooled.
Hereinafter, an aerosol-generating system, according to the second embodiment of the present disclosure, will be described.
Referring to
In the control part 160, the target temperature for each aerosol-generating article 200 may be pre-stored. Therefore, when the aerosol-generating device 100 operates in the single mode, the second heater 145 may be enabled to operate at a different temperature. In this case, the other temperature may not refer to the first or second temperature but may refer to a specific temperature (for example, 220 degrees) within the range of the second temperature. This is because this temperature may vary with the degree of filling the medium part 210 with the moisturizer and the degree of cooling by the cooling part 220.
For example, the A aerosol-generating article 200 is assumed to include the medium part 210 filled with 20% of the moisturizer and the cooling part 220 having an air dilution rate of 10%, and the B aerosol-generating article 200 is assumed to include the medium part 210 filled with 20% of the moisturizer and the cooling part 220 having an air dilution rate of 20%. In addition, the aerosol-generating article 200 is assumed to operate in the single mode. When the aerosol-generating article 200 is placed in the inlet hole 150 of the aerosol-generating device 100, the control part 160 may apply a control signal such that the second heater 145 reaches 200 degrees. In addition, when the B aerosol-generating article 200 is placed in the inlet hole 150 of the aerosol-generating device 100, the control part 160 may apply a control signal such that the second heater 145 reaches 220 degrees.
In other words, the aerosol-generating system, according to the second embodiment, enables the second heater 145 to be heated to different temperatures depending on the aerosol-generating article 200, thus providing the user with a variety of good flavors.
Although the present disclosure has been shown and described with reference to specific embodiments, it will be apparent to those skilled in the art that various modifications and changes can be made to the present disclosure without departing from the technical ideas of the present disclosure as provided by the appended claims.
