Description
TECHNICAL FIELD

The present disclosure relates to an aerosol generating device and a heater assembly for aerosol generating devices, and more particularly, to an aerosol generating device capable of generating aerosol having a rich flavor by allowing aerosol generated by a vaporizer to pass through a cigarette, and a heater assembly for aerosol generating devices.


BACKGROUND ART

Recently, there has been an increasing demand for an alternative method of overcoming the disadvantages of regular cigarettes. For example, instead of a method of generating aerosol by burning a cigarette, a method of generating aerosol by heating an aerosol generating material of a cigarette has been increasingly demanded. Accordingly, there has been active research into a heating-type cigarette and a heating-type aerosol generation device.


Conventional heating-type aerosol generating devices include a heater that is inserted into a cigarette in order to heat an aerosol generating material of the cigarette. However, when the heater is inserted into the cigarette, at least a portion of the outer surface of the cigarette is penetrated, and thus, materials of the cigarette leak to the outside of the cigarette.


To address this problem, an external heater configured to heat the outside of a cigarette without being inserted into the cigarette has been developed. However, compared with a heater directly heating an aerosol generating material of a cigarette by being inserted into the cigarette, when an external heater is used, heat transference may be reduced. Thus, technology regarding a structure of an external heater and a heat-insulation structure for preventing reduction of heat transference or reducing heat loss is in demand.


DESCRIPTION OF EXEMPLARY EMBODIMENTS
Solution to Problem

Provided are an aerosol generating device and a heater assembly for aerosol generating devices. Technical objectives of exemplary embodiments are not limited to the described technical objectives, and other technical objectives may be derived from the embodiments to be described hereinafter. For example, an aerosol generating device may include a thermally conductive element having a cylindrical shape and including an accommodation space that accommodates a cigarette; a flexible heater that surrounds at least a portion of an outer surface of the thermally conductive element; an adhesion member that surrounds an outer surface of the flexible heater to allow the flexible heater to closely adhere to the thermally conductive element; and a battery configured to supply power to the flexible heater.


Advantageous Effects of Disclosure


Provided are an aerosol generating device and a heater assembly for aerosol generating devices. In detail, an aerosol generating device according to the present disclosure may include a heater assembly for aerosol generating devices, the heater assembly including a thermally conductive element having a cylindrical shape and including an accommodation space that accommodates a cigarette, a flexible heater that surrounds at least a portion of an outer surface of the thermally conductive element, and an adhesion member that surrounds the flexible heater to allow the flexible heater to closely adhere to the thermally conductive element. Heat generated as the flexible heater operates with power supply from the battery may be delivered to a cigarette through the thermally conductive element. In this case, because the adhesion member allows the flexible heater to closely adhere to the thermally conductive element, heat loss while the heat generated by the flexible heater is being delivered to the thermally conductive element may be minimized.


At least one air gap and at least one internal housing are provided between an external housing defining the exterior of the aerosol generating device and the flexible heater, and a heat-insulation material is applied to at least one of the respective inner and outer surfaces of the external housing and the internal housing. Therefore, the heat generated by the flexible heater may be effectively prevented from being lost to the outside of the aerosol generating device.

Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the drawings.



FIGS. 1 and 2 are diagrams showing examples in which a cigarette is inserted into an aerosol generating device.


Referring to FIGS. 1 and 2, an aerosol generating device 10000 includes a battery 11000, a controller 12000, a heater assembly 13000, and a vaporizer 14000. Also, a cigarette 20000 may be inserted into an inner space of the aerosol generating device 10000.



FIGS. 1 and 2 only illustrate components of the aerosol generating device 10000, which are related to the present embodiment. Therefore, it will be understood by one of ordinary skill in the art that other general-purpose components may be further included in the aerosol generating device 10000, in addition to the components illustrated in FIG. 1.


Also, FIGS. 1 and 2 illustrate that the aerosol generating device 10000 includes the heater assembly 13000. However, as necessary, the heater assembly 13000 may be omitted.



FIG. 1 illustrates that the battery 11000, the controller 12000, the vaporizer 14000, and the heater assembly 13000 are arranged in series. On the other hand, FIG. 2 illustrates that the vaporizer 14000 and the heater assembly 13000 are arranged in parallel. However, the internal structure of the aerosol generating device 10000 is not limited to the structures illustrated in FIG. 1 or FIG. 2. In other words, according to the design of the aerosol generating device 10000, the battery 11000, the controller 12000, the vaporizer 14000, and the heater assembly 13000 may be differently arranged.


When the cigarette 20000 is inserted into the aerosol generating device 10000, the aerosol generating device 10000 may operate the vaporizer 14000 to generate aerosol. The aerosol generated by the vaporizer 14000 is delivered to the user by passing through the cigarette 20000. The vaporizer 14000 will be described in more detail later.


The battery 11000 may supply power to be used for the aerosol generating device 10000 to operate. For example, the battery 11000 may supply power to heat the heater assembly 13000 or the vaporizer 14000 and may supply power for operating the controller 12000. Also, the battery 11000 may supply power for operations of a display, a sensor, a motor, etc. mounted in the aerosol generating device 10000.


The controller 12000 may generally control operations of the aerosol generating device 10000. In detail, the controller 12000 may control not only operations of the battery 11000, the heater assembly 13000, and the vaporizer 14000, but also operations of other components included in the aerosol generating device 10000. Also, the controller 12000 may check a state of each of the components of the aerosol generating device 10000 to determine whether or not the aerosol generating device 10000 is in an operable state.


The controller 12000 may include at least one processor. A processor can be implemented as an array of a plurality of logic gates or can 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 processor can be implemented in other forms of hardware.


The heater assembly 13000 may be heated by the power supplied from the battery 11000. For example, when the cigarette 20000 is inserted into the aerosol generating device 10000, the heater assembly 13000 may be located outside the cigarette 20000 and may increase a temperature of an aerosol generating material in the cigarette 20000.


The heater assembly 13000 may include an electro-resistive heater. For example, the heater assembly 13000 may include an electrically conductive track, and the heater assembly 13000 may be heated when currents flow through the electrically conductive track. However, the heater assembly 13000 is not limited to the example described above and may include any other heaters which may be heated to a desired temperature. Here, the desired temperature may be pre-set in the aerosol generating device 10000 or may be set by a user.


Also, the aerosol generating device 10000 may include a plurality of heaters 13000. Here, the plurality of heaters 13000 may be arranged outside the cigarette 20000. In addition, the shape of the heater assembly 13000 is not limited to the shapes illustrated in FIGS. 1 and 2 and may include various shapes.


The vaporizer 14000 may generate aerosol by heating a liquid composition, and the generated aerosol may pass through the cigarette 20000 to be delivered to a user. In other words, the aerosol generated by the vaporizer 14000 may move along an air flow passage of the aerosol generating device 10000. The air flow passage may be configured such that the aerosol generated by the vaporizer 14000 passes through the cigarette 20000 to be delivered to the user.


For example, the vaporizer 14000 may include a liquid storage, a liquid delivery element, and a heating element, but it is not limited thereto. For example, the liquid storage, the liquid delivery element, and the heating element may be included in the aerosol generating device 10000 as independent modules.


The liquid storage may store a liquid composition. For example, the liquid composition may be a liquid including a tobacco-containing material having a volatile tobacco flavor component, or a liquid including a non-tobacco material. The liquid storage may be attachable to and detachable from the vaporizer 14000. Alternatively, the liquid storage may be formed integrally with the vaporizer 14000.


For example, the liquid composition may include water, a solvent, ethanol, plant extract, spices, flavorings, or a vitamin mixture. The spices may include menthol, peppermint, spearmint oil, and various fruit-flavored ingredients, but are not limited thereto. The flavorings may include ingredients capable of providing various flavors or tastes to a user. Vitamin mixtures may be a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited thereto. Also, the liquid composition may include an aerosol forming substance, such as glycerin and propylene glycol.


The liquid delivery element may deliver the liquid composition of the liquid storage to the heating element. For example, the liquid delivery element may be a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited thereto.


The heating element is an element for heating the liquid composition delivered by the liquid delivery element. For example, the heating element may be a metal heating wire, a metal hot plate, a ceramic heater, or the like, but is not limited thereto. In addition, the heating element may include a conductive filament such as nichrome wire and may be wound around the liquid delivery element. The heating element may be heated by electrical current and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, aerosol may be generated.


For example, the vaporizer 14000 may be referred to as a cartomizer or an atomizer, but it is not limited thereto.


The aerosol generating device 10000 may further include general-purpose components in addition to the battery 11000, the controller 12000, and the heater assembly 13000. For example, the aerosol generating device 10000 may include a display capable of outputting visual information and/or a motor for outputting haptic information. Also, the aerosol generating device 10000 may include at least one sensor (a puff detecting sensor, a temperature detecting sensor, a cigarette insertion detecting sensor, etc.). Also, the aerosol generating device 10000 may be formed as a structure where, even when the cigarette 20000 is inserted into the aerosol generating device 10000, external air may be introduced or internal air may be discharged.


Although not illustrated in FIGS. 1 and 2, a cradle may be used with the aerosol generating device 10000 as a system. For example, the cradle may be used to charge the battery 11000 of the aerosol generating device 10000. Alternatively, the heater assembly 13000 may be heated when the cradle and the aerosol generating device 10000 are coupled to each other.


The cigarette 20000 may be similar to a general combustive cigarette. For example, the cigarette 20000 may be divided into a first portion including an aerosol generating material and a second portion including a filter, etc. Alternatively, the second portion of the cigarette 20000 may also include an aerosol generating material. For example, an aerosol generating material made in the form of granules or capsules may be inserted into the second portion.


The entire first portion may be inserted into the aerosol generating device 10000, and the second portion may be exposed to the outside. Alternatively, the first portion may be partially inserted into the aerosol generating device 10000. Otherwise, the first portion and a part of the second portion may be inserted into the aerosol generating device 10000. The user may puff aerosol while holding the second portion by the mouth of the user. In this case, the aerosol is generated by the external air passing through the first portion, and the generated aerosol passes through the second portion and is delivered to the user's mouth.


For example, the external air may flow into at least one air passage formed in the aerosol generating device 10000. For example, opening and closing of the air passage and/or a size of the air passage may be adjusted by the user. Accordingly, the amount of smoke and a smoking impression may be adjusted by the user. As another example, the external air may flow into the cigarette 20000 through at least one hole formed in a surface of the cigarette 20000.


Hereinafter, an example of the cigarette 20000 will be described with reference to FIG. 3.



FIG. 3 is a drawing illustrating an example of a cigarette.


Referring to FIG. 3, the cigarette 20000 may include a tobacco rod 21000 and a filter rod 22000. The first portion described above with reference to FIGS. 1 and 2 may include the tobacco rod 21000, and the second portion may include the filter rod 22000.



FIG. 3 illustrates that the filter rod 22000 includes a single segment. However, the filter rod 22000 is not limited thereto. In other words, the filter rod 22000 may include a plurality of segments. For example, the filter rod 22000 may include a first segment configured to cool aerosol and a second segment configured to filter a certain component included in the aerosol. Also, as necessary, the filter rod 22000 may further include at least one segment configured to perform other functions.


The cigarette 20000 may be packaged using at least one wrapper 24000. The wrapper 24000 may have at least one hole through which external air may be introduced or internal air may be discharged. For example, the cigarette 20000 may be packaged using one wrapper 24000. As another example, the cigarette 20000 may be doubly packaged using at least two wrappers 24000. For example, the tobacco rod 21000 may be packaged using a first wrapper, and the filter rod 22000 may be packaged using a second wrapper. Also, the tobacco rod 21000 and the filter rod 22000, which are respectively packaged using separate wrappers, may be combined and packaged together using a third wrapper. When each of the tobacco rod 21000 and the filter rod 22000 includes a plurality of segments, each segment may be packaged using a separate wrapper. Also, the entire cigarette 20000 including the plurality of segments, which are respectively packaged using the separate wrappers and coupled to each other, may be re-packaged using another wrapper.


The tobacco rod 21000 may include 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, but it is not limited thereto. Also, the tobacco rod 21000 may include other additives, such as flavors, a wetting agent, and/or organic acid. Also, the tobacco rod 21000 may include a flavored liquid, such as menthol or a moisturizer, which is injected to the tobacco rod 21000.


The tobacco rod 21000 may be manufactured in various forms. For example, the tobacco rod 21000 may be formed as a sheet or a strand. Also, the tobacco rod 21000 may be formed as a pipe tobacco, which is formed of tiny bits cut from a tobacco sheet. Also, the tobacco rod 21000 may be surrounded by a thermally conductive material. For example, the thermally conductive material may be, but is not limited to, a metal foil such as aluminum foil. For example, the thermally conductive material surrounding the tobacco rod 21000 may uniformly distribute heat transmitted to the tobacco rod 21000, and thus, the heat conductivity applied to the tobacco rod may be increased and taste of the tobacco may be improved.


The filter rod 22000 may include a cellulose acetate filter. Shapes of the filter rod 22000 are not limited. For example, the filter rod 22000 may include a cylinder-type rod or a tube-type rod having a hollow inside. Also, the filter rod 22000 may include a recess-type rod. When the filter rod 22000 includes a plurality of segments, at least one of the plurality of segments may have a different shape.


The filter rod 22000 may be formed to generate flavors. For example, a flavoring liquid may be injected onto the filter rod 22000, or an additional fiber coated with a flavoring liquid may be inserted into the filter rod 22000.


Also, the filter rod 22000 may include at least one capsule 23000. Here, the capsule 23000 may generate a flavor or aerosol. For example, the capsule 23000 may have a configuration in which a liquid containing a flavoring material is wrapped with a film. For example, the capsule 23000 may have a spherical or cylindrical shape, but is not limited thereto.


When the filter rod 22000 includes a segment configured to cool the aerosol, the cooling segment may include a polymer material or a biodegradable polymer material. For example, the cooling segment may include pure polylactic acid alone, but the material for forming the cooling segment is not limited thereto. In an exemplary embodiment, the cooling segment may include a cellulose acetate filter having a plurality of holes. However, the cooling segment is not limited to the above-described example and any other cooling segment that is capable of cooling the aerosol may be used.


Although not illustrated in FIG. 3, the cigarette 20000 according to an exemplary embodiment may further include a front-end filter. The front-end filter may be located on a side of the tobacco rod 21000, which is away from the filter rod 22000. The front-end filter may prevent the tobacco rod 21000 from being detached and prevent the liquefied aerosol from flowing into the aerosol generating device 10000 (FIGS. 1 and 2) from the tobacco rod 21000, during smoking.



FIG. 4 illustrates a structure of a heater assembly for aerosol generating devices, according to an exemplary embodiment.


Referring to FIG. 4, a heater assembly 13000 for aerosol generating devices may include a thermally conductive element 410, a flexible heater 420, and an adhesion member 430. FIG. 4 only shows components related with the present embodiment from among the components of the heater assembly 13000 for aerosol generating devices. Accordingly, it will be understood by one of ordinary skill in the art that general-use components other than the components illustrated in FIG. 4 may be further included in the heater assembly 13000 for aerosol generating devices. For example, the heater assembly 13000 may further include at least one electrical connector for electrical connection between the flexible heater 420 and the battery 11000.


The thermally conductive element 410 may refer to a metal structure having an accommodation space for receiving the cigarette 20000 is formed. The thermally conductive element 410 may include a hollow that is an accommodation space for receiving the cigarette 20000. As shown in FIG. 4, the hollow included in the thermally conductive element 410 may have a circular cross-section to correspond to the shape of the cigarette 20000, and the thermally conductive element 410 may be cylindrical. However, the cross-section of the hollow included in the thermally conductive element 410 may be a polygon, and may have various sizes and shapes according to the shape of the cigarette 20000.


The thermally conductive element 410 may include a metal material having high heat conductivity. The thermally conductive element 410 may include a rigid material to accommodate the cigarette 20000 therein. For example, the thermally conductive element 410 may include copper, nickel, iron, chromium, or an alloy thereof. However, embodiments of the present disclosure are not limited thereto, and the thermally conductive element 410 may include an arbitrary suitable metal material that has high thermal transfer power and is rigid.


The flexible heater 420 may be a heater having a shape that surrounds at least a portion of the outer surface of the thermally conductive element 410. The flexible heater 420 may include a heat-resistant resin film and an electrically conductive track. The heat-resistant resin film may include one or more of polyethylene, polypropylene, polyethylene terephthalate, polycyclohexylenedimethylene terephthalate, and polyimide.


For example, the flexible heater 420 may have a structure in which a patterned electrically conductive track is laminated on a heat-resistant resin film. The flexible heater 420 may be cylindrical and may have a cylindrical shape into which a flexible flat material is rolled. However, embodiments are not limited thereto. The flexible heater 420 may be heated due to power supply from the battery 11000.


The adhesion member 430 may mean a member that surrounds an outer surface of the flexible heater 420 in order to allow the flexible heater 420 to closely adhere to the thermally conductive element 410. The flexible heater 420 closely adhering to the thermally conductive element 410 may mean that a gap between the flexible heater 420 and the thermally conductive element 410 is minimized. As the flexible heater 420 closely adheres to the thermally conductive element 410 by the adhesion member 430, heat loss while heat generated by the flexible heater 420 is being delivered to the thermally conductive element 410 may be minimized.


The adhesion member 430 may have an elastic force in a direction toward an inner surface of the adhesion member 430, or may have a property that it shrinks with an increase in the temperature. Because the adhesion member 430 has an elastic force in a direction toward an inner surface of the adhesion member 430 or has a property that it shrinks with an increase in the temperature, the flexible heater 420 surrounded by the adhesion member 430 may closely adhere to the thermally conductive element 410. For example, the adhesion member 430 may include, but is not limited to, at least one material of a heat-resistant synthetic resin, polytetrafluoroethylene (Teflon), and silicon. The adhesion member 430 may include an arbitrary suitable material having elastic force directed inward or having a property of shrinking as a temperature increases.


The adhesion member 430 may include a heat-resisting material to endure the heat generated by the flexible heater 420 and may include a heat-insulation material to prevent the heat generated by the flexible heater from being lost to the outside. The adhesion member 430 may include an arbitrary suitable material that enables the flexible heater 420 to closely adhere to the thermally conductive element 410.


Although respective lengths of the thermally conductive element 410, the flexible heater 420, and the adhesion member 430 are illustrated as decreasing in order of their arrangement in FIG. 4, this is merely for easy understanding of the structure of the heater assembly 13000 for aerosol generating devices. Each of the thermally conductive element 410, the flexible heater 420, and the adhesion member 430 may have an arbitrary suitable length. A heat-insulation structure of the aerosol generating device 10000 including the heater assembly 13000 for aerosol generating devices will now be described in detail with reference to FIG. 5.



FIG. 5 illustrates a structure of an aerosol generating device according to an exemplary embodiment.


Referring to FIG. 5, the aerosol generating device 10000 may further include an external housing 510, an internal housing 520, a first air gap 530, a second air gap 540, a first heat-insulation part 550, and a second heat-insulation part 560 in addition to the thermally conductive element 410, the flexible heater 420, and the adhesion member 430. Since the thermally conductive element 410, the flexible heater 420, and the adhesion member 430 are the same as the components of FIG. 4, repeated descriptions thereof are omitted herein. Only components related with the present embodiment from among the components of the aerosol generating device 10000 are shown in FIG. 5. Accordingly, it will be understood by one of ordinary skill in the art related with the present embodiment that general-use components other than the components illustrated in FIG. 5 may be further included in the aerosol generating device 10000.


The external housing 510 may refer to a case that forms the exterior of the aerosol generating device 10000. The external housing 510 may include a heat-resisting material, and the heat-resisting material may include a material capable of withstanding heat of 130° C. or higher. Withstanding heat of 130° C. or higher means that a melting point (Tm) of a heat-resisting material is 130° C. or higher.


The heat-resisting material may be heat-resistant synthetic resin. When the heat-resisting material is heat-resistant synthetic resin, at least one of the melting point of the heat-resisting material and a glass transition temperature (Tg) thereof may be 130° C. or higher.


For example, the heat-resisting material may include at least one of, for example, polypropylene, polyether ether ketone (PEEK), polyethylene, polypropylene, polyethylene terephthalate, polycyclohexylenedimethylene terephthalate, polyimide, sulfone-based resin, fluorine-based resin, and aramid. The sulfone-based resin may include a resin such as polyethylsulfone or polyphenylene sulfide, and the fluorine resin may include polytetrafluoroethylene (Teflon).


However, the heat-resisting material is not limited thereto. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 80° C. or higher, or the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 100° C. or higher. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 150° C. or higher. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 200° C. or higher. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 300° C. or higher. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 400° C. or higher.


At least one air gap and at least one internal housing may be located between the external housing 510 and the flexible heater 420. For example, the aerosol generating device 10000 may further include the internal housing 520, the first air gap 530, and the second air gap 540 that are located between the external housing 510 and the flexible heater 420. Although a single internal housing and two air gaps are shown in FIG. 5, the number of air gaps and the number of internal housings may be arbitrary suitable numbers.


The internal housing 520 may form the internal structure of the aerosol generating device 10000. The internal housing 520 may include a heat-resisting material, which may include a material capable of withstanding heat of 130° C. or higher.


The heat-resisting material may be heat-resistant synthetic resin. When the heat-resisting material is heat-resistant synthetic resin, at least one of the melting point of the heat-resisting material and a glass transition temperature (Tg) thereof may be 80° C. or higher. For example, the heat-resisting material may include at least one of, for example, polypropylene, polyether ether ketone (PEEK), polyethylene, polyimide, sulfone-based resin, fluorine-based resin, and aramid. The sulfone-based resin may include a resin such as polyethylsulfone or polyphenylene sulfide, and the fluorine resin may include polytetrafluoroethylene (teflon).


However, the heat-resisting material is not limited thereto. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 80° C. or higher, or the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 100° C. or higher. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 150° C. or higher. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 200° C. or higher. For example, the heat-resisting material may be an arbitrary suitable material capable of withstanding heat of 300° C. or higher.

The first air gap 530 may be an air gap between the flexible heater 420 and the internal housing 520, and the second air gap 540 may be an air gap between the internal housing 520 and the external housing 510. Heat transfer from the flexible heater 420 to the internal housing 520 may be reduced by the first air gap 530, and heat transfer from the internal housing 520 to the external housing 510 may be reduced by the second air gap 540. Accordingly, external heat loss of the aerosol generating device 10000 may be minimized.


The aerosol generating device 10000 may include a heat-insulation part on at least one of respective inner and outer surfaces of the external housing 510 and the internal housing 520. The heat-insulation part may include at least one heat-insulation material. For example, the first heat-insulation part 550 and the second heat-insulation part 560 may include an arbitrary suitable material that blocks movement of heat via the first insulation part 550 and the second insulation part 560. For example, the first heat-insulation part 550 and the second heat-insulation part 560 may include, but are not limited to, at least one material of a porous material, graphite, and ceramic. The ceramic may be porous ceramic.


Referring to FIG. 5, the first heat-insulation part 550 is located in contact with the inner surface of the external housing 510, and the second insulation part 560 is located in contact with the outer surface of the internal housing 520. However, this is merely an example, and the first heat-insulation part 550 may be located in contact with the outer surface of the external housing 510, and the second insulation part 560 may be located in contact with the inner surface of the internal housing 520. Also, a heat-insulation material may be applied to all of the respective inner and outer surfaces of the external housing 510 and the internal housing 520.


The aerosol generating device 10000 according to the present disclosure includes the first and second air gaps 530 and 540 and the internal housing 520 between the external housing 510 forming the exterior of the aerosol generating device 10000 and the flexible heater 420, and heat-insulation materials are applied to at least one of the respective inner and outer surfaces of the external housing 510 and the internal housing 520 of the aerosol generating device 10000. Therefore, the heat generated by the flexible heater 420 may be effectively prevented from being lost to the outside of the aerosol generating device 10000.


It will be understood by those of ordinary skill in the art that various changes in form and details may be made to the exemplary embodiments without departing from the intrinsic characteristics of the above descriptions. It should be understood that the disclosed methods should be considered in a descriptive sense only and not for purposes of limitation. Therefore, the scope of the present disclosure is defined not by the detailed description of the present disclosure but by the appended claims, and all differences within the scope will be construed as being included in the present disclosure.
