Description

Aerosol generating device

[0001] Embodiments relate to an aerosol generating device comprising a detachable battery.

[0002] Recently, there has been a growing demand for alternative methods that overcome the shortcomings of conventional cigarettes. For example, there is a growing demand for systems that generate aerosol by heating cigarettes (or "aerosol-generating articles") using an aerosol-generating device, rather than by burning the cigarette itself.

[0003] An aerosol generating device includes a battery for power supply and a heater for generating heat as power is supplied. The heater heats an aerosol-generating material to generate an aerosol. While aerosol generating devices can utilize an integrated battery for miniaturization, research is actively underway on aerosol generating devices that utilize a detachable battery to enhance user convenience.

[0004] The battery in an aerosol generator may generate heat during use or charging. In particular, if the battery in an aerosol generator ages or is exposed to external impacts, its durability may be weakened, resulting in an abnormally large amount of heat being generated from the battery.

[0005] This overheating phenomenon can cause internal components of the aerosol generator to malfunction or fail, potentially causing burns to the hands of users. Furthermore, the aerosol generated by the aerosol generator may not cool to a temperature suitable for inhalation.

[0006] Various embodiments of the present disclosure aim to prevent an aerosol generating device from malfunctioning or being damaged by heat generated from a battery of the aerosol generating device and to prevent the performance of the aerosol generating device from being deteriorated.

[0007] The problems to be solved through the embodiments of the present disclosure are not limited to the problems described above, and problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the embodiments belong from this specification and the attached drawings.

[0008] An aerosol generating device according to one embodiment may include a housing including a first receiving space for receiving an aerosol generating article, a second receiving space for receiving a cartridge storing an aerosol generating substance, and a battery receiving space, a first airflow passage disposed inside the housing and connecting the first receiving space and the second receiving space, a first heat dissipation member disposed between the first airflow passage and the battery receiving space for absorbing heat inside the battery receiving space, and a battery detachably coupled to the battery receiving space.

[0009] The aerosol generating device according to various embodiments of the present disclosure can prevent damage and malfunction of the aerosol generating device in advance and prevent the performance of the aerosol generating device from deteriorating by absorbing or releasing heat generated from the battery of the aerosol generating device.

[0048] Figure 1 is a perspective view of an aerosol generating device according to one embodiment.

[0049] The aerosol generating device (100) can generate and provide an aerosol.

[0050] Referring to FIG. 1, an aerosol generating device (100) according to one embodiment may include a housing (101). The housing (101) may form the overall exterior of the aerosol generating device (100) and may include a space therein. Various components for generating and providing an aerosol may be arranged in the interior space (or 'mounting space') of the housing (101).

[0051] The housing (101) may include a first receiving space (210) into which an aerosol generating article (200) is inserted, a cover (102) for opening or closing the first receiving space (210), and a battery receiving space (110) in which a battery (111) is received.

[0052] The first receiving space (210) may provide a space into which an aerosol generating article (200) is detachably inserted (or 'coupled'). The aerosol generating article (200) may include an aerosol generating material that is heated by a heater to generate an aerosol. The first receiving space (210) may provide a space open toward the outside of the housing (101) into which the aerosol generating article (200) is inserted.

[0053] The first receiving space (210) may be recessed toward the interior of the housing (101) such that at least a portion of the aerosol-generating article (200) can be inserted therein. The depth to which the first receiving space (210) is recessed may correspond to the length of a region of the aerosol-generating article (200) containing the aerosol-generating material and / or medium. A portion of the aerosol-generating article (200) may be inserted into the interior of the housing (101), and another portion of the aerosol-generating article (200) may protrude toward the exterior of the housing (101). A user may hold a portion of the aerosol-generating article (200) exposed toward the exterior of the housing (101) in his / her mouth and inhale air containing the aerosol.

[0054] The cover (102) can open or close the first receiving space (210). The cover (102) can be movably arranged in the housing (101) to expose the first receiving space (210) to the outside of the aerosol generating device (100), or can cover the first receiving space (210) so that the first receiving space (210) is not exposed to the outside of the aerosol generating device (100). The cover (102) can open the first receiving space (210) while being positioned in the first region of the housing (101), and an aerosol generating article (200) can be inserted into the opened first receiving space (210). The cover (102) can be moved from the first region of the housing (101) to the second region to close the first receiving space (210). The cover (102) is positioned in the second area of ​​the housing (101) so that the first receiving space (210) is not exposed to the outside, thereby protecting the first receiving space (210) from external impact or foreign substances.

[0055] The battery receiving space (110) can receive a battery (111) for supplying power to a heater for heating an aerosol generating article (200). The battery receiving space (110) can be formed on one side of the housing (101) (e.g., the side facing the +x axis) to receive the battery (111). The location where the battery receiving space (110) is formed is not limited thereto, and the battery receiving space (110) can also be formed in an internal area of ​​the housing (101).

[0056] The battery (111) can be detachably coupled to the battery receiving space (110) and can supply power for the operation of components of the aerosol generating device (100). The battery (111) accommodated in the battery receiving space (110) can be coupled to the battery receiving space (110) and electrically connected to components of the aerosol generating device (100) (e.g., heater, processor).

[0057] For example, the battery receiving space (110) may be provided with a terminal for electrically connecting to the battery (111), and the battery (111) may be provided with a terminal for supplying power to the aerosol generating device (100) through the terminal provided in the battery receiving space (110). The battery (111) may supply power for operating components of the aerosol generating device (100) through the terminal provided in the battery (111) and the terminal provided in the battery receiving space (110).

[0058] The battery (111) can be charged while attached to the battery receiving space (110) and / or while detached from the battery receiving space (110). While the battery (111) is received in the battery receiving space (110), the aerosol generating device (100) can be electrically connected to an external charger, and power supplied from the external charger can be supplied to the battery (111) through a terminal provided in the battery receiving space (110) and a terminal provided in the battery (111), thereby charging the battery (111). The method by which the battery (111) is charged is not limited thereto. The battery (111) can be detached from the battery receiving space (110) and connected to or received in an external charger independently of the aerosol generating device (100). The battery (111) can be charged by receiving power from the external charger through a terminal provided in the battery (111).

[0059] When the battery (111) is charged or used, heat may be generated from the battery (111). The heat generated from the battery (111) may affect the performance of other components (e.g., heater, processor, etc.) of the aerosol generating device (100) disposed around the battery (111). In particular, when the battery (111) is overcharged or overdischarged, excessive heat may be generated from the battery (111), which may cause malfunction and / or damage to other components of the aerosol generating device (100) disposed around the battery (111).

[0060] The chemical and / or physical properties of the battery (111) may deteriorate with use. For example, the internal resistance of the battery (111) may increase with use, thereby reducing the usable capacity of the battery (111). A worn-out battery (111) may need to be replaced with a new battery (111) periodically. A worn-out battery (111) may be manually and / or automatically removed from the aerosol generating device (100), and a new battery (111) may be newly attached to the aerosol generating device (100).

[0061] Excessive heat may be generated from a battery (111) that has reached the end of its lifespan or has been subjected to external impact. If the battery (111) ages or is subjected to external impact, the durability of the battery (111) may be weakened. A battery (111) with weakened durability may operate abnormally, and an abnormally large amount of heat may be generated from the battery (111). Excessive heat generated from a battery (111) that has aged or been subjected to external impact may cause malfunction and / or damage to other components of the aerosol generating device (100) disposed around the battery (111).

[0062] Although not shown, the aerosol generating device (100) may further include a battery cover detachably coupled to the housing (101) to protect the battery (111). When the battery cover is detached from the housing (101), the battery receiving space (110) and at least a portion of the battery may be exposed to the outside of the aerosol generating device (100). Through the open battery receiving space (110), a battery (111) that has reached the end of its lifespan may be replaced with a new battery (111). The battery cover may be attached to the housing (101) to close the battery receiving space (110). The battery (111) accommodated in the closed battery receiving space (110) may be protected from external foreign substances and may be fixed inside the battery receiving space (110) by the battery cover. The aerosol generating device (100) may further include a fixing member that is arranged in the battery receiving space (110) and / or the battery cover to fix the battery (111) to the battery receiving space (110). By fixing the battery (111) to the battery receiving space (110) using the fixing member, the aerosol generating device (100) can prevent the battery (111) from being easily separated from the aerosol generating device (100) due to external physical impact.

[0063] FIGS. 2A to 2E are various examples for explaining the configuration of the aerosol generating device of FIG. 1. Referring to FIGS. 2A to 2E, the aerosol generating device (100) may include a battery (111), a processor (130), and a heater (120a to 120e). The components of the aerosol generating device (100) may be identical or similar to at least one of the components of the aerosol generating device (100) of FIGS. 1 to 2, and any redundant description thereof will be omitted below.

[0064] The aerosol generating device (100) can be implemented in various ways. For example, the aerosol generating device (100) can utilize an electrical resistance heating method or an induction heating method. As another example, the aerosol generating device (100) can also be implemented to further include a vaporizer or a cartridge. The aerosol generating device (100) of FIGS. 2A to 2E discloses components related to embodiments of the present disclosure, and a person skilled in the art related to embodiments of the present disclosure will readily understand that, in addition to the components illustrated in FIGS. 2A to 2E, other components may be further included in the aerosol generating device (100).

[0065] FIG. 2A is a drawing for explaining an electric resistance type aerosol generating device (100) according to an example. Referring to FIG. 2A, the aerosol generating device (100) may include a battery (111), a heater (120a), and a processor (130).

[0066] An aerosol generating article (200) can be inserted into an internal receiving space (e.g., the first receiving space (210) of FIG. 1) of an aerosol generating device (100). When the aerosol generating article (20) is inserted into the aerosol generating device (100), the aerosol generating device (100) can generate an aerosol from the aerosol generating article (200) by heating the aerosol generating article (200) using a heater (120a). The generated aerosol passes through the aerosol generating article (200) and is delivered to the user, so that the user can smoke the aerosol generating article (20).

[0067] The heater (120a) can be heated by power supplied from the battery (111). The heater (120a) may be an electrical resistance heater. For example, the heater (120a) includes an electrically conductive track, and the heater (120a) can be heated as current flows through the electrically conductive track.

[0068] The electrically conductive track of the heater (120a) is made of an electrically resistive material, so that the heating temperature can be determined according to the power consumption of the resistor, and the resistance value of the electrically conductive track can be set based on the power consumption of the resistor of the electrically conductive track. The resistance value of the electrically conductive track can be set in various ways depending on the constituent material, length, width, thickness, or pattern of the electrically resistive material.

[0069] The internal resistance of an electrically conductive track may increase as the temperature increases, depending on its temperature coefficient of resistance characteristics. For example, the temperature and resistance of the electrically conductive track may be proportional within a given temperature range. Using this principle, a heater (120a) made of an electrically conductive track can heat an aerosol-generating article (200) via electrical resistance.

[0070] The electrically conductive tracks can be made of tungsten, gold, platinum, silver, copper, nickel, palladium, or a combination thereof. Additionally, the electrically conductive tracks can be doped with a suitable doping agent and include an alloy.

[0071] The shape of the heater (120a) can be manufactured in various ways, such as a tube shape, a plate shape, a needle shape, or a rod shape. In addition, a plurality of heaters (120a) can be arranged. The heater (120a) can be inserted into the interior of the aerosol generating article (200) and used as an internal heating method to heat the interior of the aerosol generating article (200).

[0072] The battery (111) can be separated from or mounted on the aerosol generating device (100), and when the battery (111) is attached to the aerosol generating device (100), power can be supplied from the battery (111) to the heater (120a) for heating operation of the heater (120a), thereby controlling the temperature of the electrically conductive track.

[0073] The processor (130) can control the heating operation of the heater (120a) by controlling the power supplied to the heater (120a). For example, the processor (130) can control the temperature at which the aerosol generating article (20) is heated by the heater (120a) according to a temperature profile.

[0074] FIGS. 2b and 2c are drawings for explaining an aerosol generating device (100) additionally equipped with a vaporizer (125b, 125c) according to an example. Referring to FIGS. 2b and 2c, the aerosol generating device (100) may be an aerosol generating device (100) that further includes a vaporizer (125b, 125c) in addition to the aerosol generating device (100) of FIG. 2a.

[0075] In Fig. 2b, the vaporizer (125b) and the heater (120b) are depicted as being arranged in a row, while in Fig. 2c, the vaporizer (125c) and the heater (120c) are depicted as being arranged in parallel. That is, the aerosol generating device (100) can be distinguished depending on how the vaporizers (125b, 125c) are arranged.

[0076] The heaters (120b, 120c) can be heated by power supplied from the battery (111). The heaters (120b, 120c) are electrical resistive heaters and may include, for example, electrically conductive tracks.

[0077] Unlike the heater (120a) of FIG. 2a, the heaters (120b, 120c) of FIGS. 2b and 2c can be implemented in an external heating manner by being placed around the outer periphery of the aerosol generating article (200) to heat the outer surface of the aerosol generating article (200).

[0078] The vaporizer (125b, 125c) can heat the liquid composition to generate an aerosol, and the generated aerosol can be delivered to the user by passing through the aerosol generating article (200). That is, the aerosol generated by the vaporizer (125b, 125c) can be transported along the airflow passage of the aerosol generating device (100), and the airflow passage can be configured so that the aerosol generated by the vaporizer (125b, 125c) can pass through the aerosol generating article (200) and be delivered to the user.

[0079] The vaporizer (125b, 125c) may include a liquid storage unit, a liquid delivery means, and a heating element (or vaporization element). However, the liquid storage unit, the liquid delivery means, and the heating element may each be positioned as independent modules in a different location within the aerosol generating device (100) rather than within the vaporizer (125b, 125c).

[0080] The liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing a tobacco-containing substance including a volatile tobacco flavoring component, or a liquid containing a non-tobacco substance. The liquid reservoir can be designed to be detachable from / attached to the vaporizer (125b, 125c), or can be designed as an integral part of the vaporizer (125b, 125c). For example, the liquid composition can include water, a solvent, ethanol, a plant extract, a flavoring agent, a flavoring agent, or a vitamin mixture. Additionally, the liquid composition can include an aerosol-forming agent such as glycerin and propylene glycol.

[0081] The liquid delivery means can deliver the liquid composition from the liquid storage to the heating element. For example, the liquid delivery means can be, but is not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0082] The heating element provided in the vaporizer (125b, 125c) is an element for heating (vaporizing) the liquid composition delivered by the liquid delivery means. For example, the heating element may be, but is not limited to, a metal heating wire, a metal heating plate, a ceramic heater, etc. In addition, the heating element may be composed of a conductive filament such as a nichrome wire and may be arranged in a structure that is wound around the liquid delivery means. The heating element may be heated by a current supply and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol may be generated. Accordingly, the vaporizer (125b, 125c) may also be referred to by other terms such as a cartomizer or an atomizer.

[0083] The battery (111) can be separated from or mounted on the aerosol generating device (100), and when the battery (111) is mounted on the aerosol generating device (100), power can be supplied from the battery (111) to the heaters (120b, 120c) and the vaporizers (125b, 125c) for heating operations of the heaters (120b, 120c) and the vaporizers (125b, 125c).

[0084] The processor (130) can control the heating operation of the heaters (120b, 120c) and the vaporizers (125b, 125c) by controlling the power supplied to the heaters (120b, 120c) and the vaporizers (125b, 125c). For example, the processor (130) can control the temperature at which the aerosol generating article (200) is heated by the heaters (120b, 120c) and the vaporizers (125b, 125c) according to a temperature profile.

[0085] FIG. 2d is a drawing for explaining an aerosol generating device (100) using an induction heating method according to an example. Referring to FIG. 2d, the aerosol generating device (100) may include a heater (120d) including a coil (121d) and a susceptor (122d), a battery (111), and a processor (130).

[0086] The aerosol generating device (100) can generate an aerosol by heating an aerosol generating article (200) accommodated in the aerosol generating device (100) using an induction heating method. The induction heating method may refer to a method of heating a magnetic body that generates heat by applying an alternating magnetic field whose direction changes periodically to the magnetic body that generates heat due to an external magnetic field. Accordingly, the aerosol generating device (100) can emit thermal energy from the magnetic body by applying an alternating magnetic field to the magnetic body, and can heat the aerosol generating article (200) by transferring the thermal energy emitted from the magnetic body to the aerosol generating article. Here, the magnetic body that generates heat due to the external magnetic field may be a susceptor (122d). The susceptor (122d) may be provided in the aerosol generating device (100). Alternatively, the susceptor (122d) may be provided inside the aerosol generating article (200) in the shape of a piece, flake, strip, etc. instead of being provided in the aerosol generating device (100).

[0087] The susceptor (122d) may be formed of a ferromagnetic substance. For example, the material of the susceptor (122d) may include a metal or carbon. The material of the susceptor (122d) may include at least one of ferrite, a ferromagnetic alloy, stainless steel, and aluminum (Al). In addition, the material of the susceptor (122d) may include at least one of a ceramic such as graphite or zirconia, a transition metal such as nickel (Ni) or cobalt (Co), and a metalloid such as boron (B) or phosphorus (P).

[0088] The aerosol generating device (100) can accommodate an aerosol generating article (200). A space for accommodating the aerosol generating article (200) can be formed in the aerosol generating device (200d). A susceptor (122d) can be arranged around the periphery of the space accommodating the aerosol generating article (200). For example, the susceptor (122d) can have a cylindrical shape that surrounds the exterior of the aerosol generating article (200). Therefore, when the aerosol generating article (200) is accommodated in the aerosol generating device (200d), the aerosol generating article (200) can be accommodated in the accommodation space of the susceptor (122d), and the susceptor (122d) can be arranged at a position that surrounds at least a portion of the outer surface of the aerosol generating article (200). However, the shape of the susceptor (122d) is not limited thereto and may vary.

[0089] The heater (120d) is an induction heating method, and the heater (120d) can heat an aerosol generating article (200) accommodated in an aerosol generating device (100) by using a susceptor (122d) that generates heat by an external magnetic field generated by a coil (121d).

[0090] The coil (121d) is arranged to be wound along the outer surface of the susceptor (122d), so that an alternating magnetic field can be applied to the susceptor (122d). When power is supplied to the coil (121d) from the aerosol generating device (100), a magnetic field can be formed in an internal region of the coil (121d). When an alternating current is applied to the coil (121d), the direction of the magnetic field formed inside the coil (121d) can be continuously changed. When the susceptor (122d) is positioned inside the coil (121d) and is exposed to an alternating magnetic field whose direction changes periodically, the susceptor (122d) can generate heat, and a cigarette accommodated in the susceptor (122d) can be heated. The shape of the coil (121d) may be a cylindrical shape wound along the length direction of the aerosol generating article (200), but is not limited thereto, and the coil (121d) may be implemented in various types such as a flat coil.

The plate (B35) of the frame (B33) can cover and seal the open portion of the first chamber (C1). The plate (B35) can cover the upper portion of the frame (B33). The plate (B35) can cover and seal the open portion of the second chamber (BC2).

[0150] The plate (B35) may have a connecting hole (B351) on one side. The connecting hole (B351) may be located between the inlet passage (B302) and the chamber inlet (B303). The connecting hole (B351) may connect the inlet passage (B302) and the chamber inlet (B303).

[0151] The plate (B35) may be provided with a liquid inlet hole (B354). The liquid inlet holes (B354) may be formed in pairs at positions corresponding to the wick coupling grooves (B334). The pair of liquid inlet holes (B354) may be located on the upper side of both ends of the wick (B341). The liquid inlet holes (B354) may connect the first chamber (C1) and the wick coupling groove (B334). The wick (B341) may be connected to the first chamber (C1) through the liquid inlet holes (B354).

[0152] The hook groove (B335) may be formed on the upper side of the chamber outlet (B332) at a position adjacent to the chamber outlet (B332). The hook groove (B335) may protrude downward from one side of the plate (B35). The hook (B353) may be inserted into and fastened to the hook groove (B335) formed on the upper side of the frame (B33). The plate (B35) is fastened to the frame (B33), and the first container (B31) coupled to the second container (B32) may press the edge portion of the plate (B35) toward the frame (B33).

[0153] The user can inhale air by holding the stick (S) inserted into the insertion space (B134) in his / her mouth. When the upper case (B200) is connected to the body (B100), air can flow into the cartridge inlet (B301) through the opening (B201) formed in the upper case (B200). The air can flow into the interior of the cartridge (B300) through the cartridge inlet (B301) and be discharged to the exterior of the cartridge (B300) through the cartridge outlet (B304). The air drawn into the interior of the cartridge (B300) can be discharged to the exterior by sequentially passing through the inlet path (B302), the connecting hole (B351), the chamber inlet (B303), the second chamber (BC2), the chamber outlet (B332), and the cartridge outlet (B304).

[0154] When the heater (B342) heats the wick (B341), an aerosol may be formed from the wick (B341) within the second chamber (BC2). Air passing through the cartridge (B300) may be discharged from the second chamber (B2) through the cartridge discharge port (B304) accompanied by the aerosol. The air discharged through the cartridge discharge port (B304) may be supplied to the insertion space (B134) and the stick (S) inserted into the insertion space (B134) through the connecting passage (B133).

[0155] Referring to FIG. 3f, the upper body (B120) may have an outer wall (B121) and a partition wall (B125). The outer wall (B121) and the partition wall (B125) may be connected. The partition wall (B125) may be formed to extend vertically between the pipe (B130) and the cartridge coupling space (B124a).

[0156] The extension (B140) may be formed by extending to one side from the upper part of the upper body (B120). The upper surface (B312) of the cartridge (B300) may be covered by the extension (B140). The extension (B140) may cover the cartridge inlet (B301) and its surroundings. A gap may be formed between the extension (B140) and the cartridge inlet (B301) and between the lower part of the extension (B140) and the upper surface (B312) of the cartridge (B300). The gap may connect the cartridge inlet (B301) to the outside.

[0157] The pipe (B130) may be formed to be elongated in the vertical direction. The pipe (B130) may be formed to be hollow. An insertion space (B134) may be formed inside the pipe (B130). The insertion space (B134) may be opened upward. The insertion space (B134) may extend vertically. A connection path (B133) may be formed inside the pipe (B130). The connection path (B133) may be formed at the lower side of the insertion space (B134). One end of the connection path (B133) may be connected to the outside of the pipe (B130), and the other end may be connected to the insertion space (B134). The connection path (B133) may be bent to one side from the lower part of the insertion space (B134).

[0158] The first sensor (B161) may be installed inside the extension portion (B140). The first sensor (B161) may face the upper surface of the cartridge (B300) or the cartridge inlet (B301). The first sensor (B161) may be installed adjacent to the cartridge inlet (B301). The first sensor (B161) may be located above the cartridge inlet (B301). The first sensor (B161) may overlap the cartridge inlet (B301) in the vertical direction.

[0159] The first sensor (B161) can sense the surrounding air flow. The first sensor (B161) may be an air flow sensor or a pressure sensor. The first sensor (B161) can sense the air flow through changes in the surrounding air pressure. At a location adjacent to the cartridge inlet (B301), the extension (B140) can have a hole for sensing the air flow. The first sensor (B161) can be mounted on a substrate arranged inside the extension (B140) and can be electrically connected to the control unit (B20). The control unit (B20) can control the operations of various connected components based on the first sensor (B161) detecting the air flow.

[0160] The first sealing portion (B151) may be positioned between the first bulkhead portion (B1251) and the inner plate (B171). The first sealing portion (B151) may be tightly attached to the upper portion of the first bulkhead portion (B1251). The first sealing portion (B151) may be tightly attached to the lower portion of the inner plate (B171).

[0161] The sensor receiving portion (B156) of the second sealing portion (B152) can seal the periphery of the first sensing hole (B144). The sensor receiving portion (B156) can be in close contact with the extension plate (B141) around the first sensing hole (B144).

The sensor receiving portion (B156) can be in close contact with and surround the first sensor (B161).

[0162] Accordingly, it is possible to prevent failure of the substrate or sensor due to foreign substances or aerosol discharged around the opening of the pipe (B130) or foreign substances through the first sensing hole (B144).

[0163] FIG. 4 is a cross-sectional view illustrating a first heat dissipation member, a first airflow passage, and a second airflow passage of an aerosol generating device according to one embodiment.

[0164] Referring to FIG. 4, an aerosol generating device (100) according to an embodiment may include a housing (101), a first receiving space (210), a second receiving space (310), a battery receiving space (110), a first heat dissipation member (420), a first airflow passage (400), and a second airflow passage (410). Components of the aerosol generating device (100) according to an embodiment may be identical or similar to at least one of the components of the aerosol generating device (100) of FIG. 1, FIG. 2A to FIG. 2B, and FIG. 3A to FIG. 3F, and any overlapping description will be omitted below. The solid arrows in FIG. 4 represent the flow of air, and the dotted arrows in FIG. 4 represent the flow of aerosol.

[0165] The housing (101) may include a first receiving space (210) for receiving an aerosol generating article (200), a second receiving space (310) for receiving a cartridge (300), and a battery receiving space (110) for receiving a battery (111).

[0166] The housing (101) can form the overall appearance of the aerosol generating device (100), and components of the aerosol generating device (100) can be arranged in the interior space of the housing (101). For example, a first receiving space (210), a second receiving space (310), and a battery receiving space (110) can be arranged in the interior of the housing (101). However, this is not limited thereto, and for another example, a battery and a processor may be further arranged in the interior of the housing (101).

[0167] At least a portion of the aerosol-generating article (200) may be inserted into the first receiving space (210). The length of the aerosol-generating article (200) inserted into the first receiving space (210) may correspond to the length of the region of the aerosol-generating article (200) containing the aerosol-generating material and / or medium. A portion of the aerosol-generating article (200) may be inserted into the interior of the housing (101), and another portion of the aerosol-generating article (200) may protrude toward the exterior of the housing (101).

[0168] When the aerosol generating article (200) is inserted into the first receiving space (210), the aerosol generating material and / or medium can be heated by the article heater (230) to generate vapor. The vapor generated from the aerosol generating article (200) can be mixed with air introduced into the first receiving space (210) to generate an aerosol. The user can inhale the generated aerosol by contacting the other part of the aerosol generating article (200) protruding toward the outside of the housing (101).

[0169] The cartridge (300) may include a storage tank (320) in which an aerosol generating substance is stored and an atomizing unit having a cartridge heater (330) for heating the aerosol generating substance. When the cartridge (300) is accommodated in the second receiving space (310), the aerosol generating substance stored in the storage tank (320) may be heated by the cartridge heater (330) to generate vapor. The vapor generated from the cartridge (300) may be mixed with air introduced into the second receiving space (310) to generate an aerosol.

[0170] The first airflow passage (400) is arranged inside the housing (101) and can connect the first receiving space (210) and the second receiving space (310). The aerosol generated from the cartridge (300) received in the second receiving space (310) can be introduced into the first receiving space (210) through the first airflow passage (400) and mixed with the aerosol generated from the aerosol generating article (200) inserted into the first receiving space (210). The user can inhale the mixed aerosol by contacting the other part of the aerosol generating article (200) protruding toward the outside of the housing (101).

[0171] The aerosol generated from the cartridge (300) may be cooled while moving from the second receiving space (310) to the first receiving space (210) along the first airflow passage (400). Since the aerosol generated from the cartridge (300) may be mixed with the aerosol generated from the aerosol generating article (200) in a cooled state, the mixed aerosol may also be cooled. Accordingly, the user may inhale the aerosol cooled to a temperature suitable for inhalation by contacting the other part of the aerosol generating article (200) protruding toward the outside of the housing (101) with the bent part.

[0172] The aerosol generating device (100) may be disposed inside the housing (101) and may include a first heat dissipation member (420) for absorbing heat generated inside the battery receiving space (110). For example, the first heat dissipation member (420) may be disposed between the first airflow passage (400) and the battery receiving space (110) and may absorb heat generated inside the battery receiving space (110).

[0173] The battery (111) may be detachably coupled to the battery receiving space (110). The battery (111) may be coupled to the battery receiving space (110) to supply power for the operation of components of the aerosol generating device (100). When the battery (111) is charged or used, heat may be generated from the battery (111), and the heat generated from the battery (111) may affect the performance of the aerosol generating device (100). For example, the heat generated from the battery (111) may prevent the aerosol moving along the first airflow passage (400) from being cooled to an appropriate temperature.

[0174] If the battery (111) is overcharged or overdischarged, or if the battery (111) ages or is subjected to external impact and its durability is weakened, an abnormally large amount of heat may be generated from the battery (111). The excessive heat generated from the battery (111) may affect the performance of other components of the aerosol generating device (100) arranged around the battery (111). For example, the heater for the article (230) and / or the heater for the cartridge (330) may malfunction and / or be damaged due to the excessive heat generated from the battery (111).

[0175] The first heat dissipation member (420) is arranged between the first airflow passage (400) and the battery receiving space (110), so as to prevent heat generated from the battery (111) from being transferred from the battery receiving space (110) to the first airflow passage (400), the product heater (230), and / or the cartridge heater (330).

[0176] The first heat dissipation member (420) can absorb heat generated inside the battery receiving space (110) and prevent heat generated from the battery (111) from being transferred to the first airflow passage (400). The first heat dissipation member (420) can prevent the temperature of the aerosol generated from the cartridge (300) and / or the aerosol generated from the aerosol generating article (200) from increasing due to heat generated from the battery (111). The aerosol generating device (100) has the first heat dissipation member (420) disposed between the first airflow passage (400) and the battery receiving space (110), so that the user can inhale the aerosol cooled to an appropriate temperature.

[0177] The first heat dissipation member (420) can absorb heat generated inside the battery receiving space (110), thereby preventing heat generated from the battery (111) from being transferred to the product heater (230) and the cartridge heater (330). The aerosol generating device (100) can prevent malfunction and / or damage to the product heater (230) and the cartridge heater (330) due to heat generated from the battery (111) by having the first heat dissipation member (420) disposed between the first airflow passage (400) and the battery receiving space (110).

[0178] For another example, the first heat dissipation member (420) may be arranged around the battery receiving space (110) inside the housing (101) to absorb heat generated inside the battery receiving space (110). The first heat dissipation member (420) may be arranged to surround at least one area of ​​the outer circumferential surface of the battery receiving space (110) inside the housing (101).

[0179] The first heat dissipation member (420) is arranged around the battery receiving space (110) inside the housing (101), so as to prevent heat generated from the battery (111) from being transferred from the battery receiving space (110) to the product heater (230) and / or the cartridge heater (330). The aerosol generating device (100) has the first heat dissipation member (420) arranged between the first airflow passage (400) and the battery receiving space (110), so as to prevent malfunction and / or damage to the product heater (230) and the cartridge heater (330) due to heat generated from the battery (111).

[0180] A second airflow passage (410) may be arranged inside the housing (101) to connect the outside of the aerosol generating device (100) and the battery receiving space (110). The outside air may move into the inside of the battery receiving space (110) along the second airflow passage (410) and then move back to the outside of the aerosol generating device (100) along the second airflow passage (410).

[0181] The housing (101) may further include one or more air holes penetrating the housing (101). Outside air may be drawn into the interior of the aerosol generating device (100) through one air hole, move along the second air flow passage (410) into the interior of the battery receiving space (110), and then move again along the second air flow passage (410) to be discharged to the exterior of the aerosol generating device (100) through another air hole.

[0182] The second airflow passage (410) may include one or more small holes in at least one area (e.g., area A illustrated in FIG. 4). For example, referring to FIG. 5A, the second airflow passage (410) may include a plurality of perforations (510). As the plurality of perforations (510) are arranged in the second airflow passage (410), the ventilation of the battery receiving space (110) may be improved. For another example, referring to FIG. 5B, the second airflow passage (410) may include a mesh-shaped structure (520). For example, the mesh-shaped structure (520) may be a sheet of metal. However, the present invention is not limited thereto, and for another example, the mesh-shaped structure (520) may be a sheet including plastic or polyethylene terephthalate (PET). As the second airflow passage (410) includes a mesh-shaped structure (520), the breathability of the battery accommodation space (110) can be improved.

[0183] The second airflow passage (410) can effectively release heat generated from the battery (111), thereby minimizing external heat generation of the battery receiving space (110). If excessive heat is generated from the battery (111), components of the aerosol generating device (100) arranged around the battery (111) may break down or malfunction due to the heat. In addition, the battery receiving space (110) may heat to an excessively high temperature due to the excessive heat generated from the battery (111), and thus, users using the aerosol generating device (100) may suffer burns on their hands.

[0184] The aerosol generating device (100) can prevent internal components of the aerosol generating device (100) from malfunctioning and / or being damaged by heat generated from the battery (111) by minimizing external heat generation of the battery receiving space (110) through the second airflow passage (410), and can prevent users of the aerosol generating device (100) from getting burned on their hands by heat generated from the battery (111).

[0185] FIG. 6 is a drawing for explaining a second heat dissipation member of an aerosol generating device according to an embodiment. Referring to FIG. 6, an aerosol generating device (100) according to an embodiment may include a housing (101), a battery (111), a second heat dissipation member (440), and a battery cover (600). FIG. 6 only briefly illustrates components of an aerosol generating device (100) for explaining the second heat dissipation member (440) and the battery cover (600), and the components included in the aerosol generating device (100) according to an embodiment are not limited to the components illustrated in FIG. 6. The components of the aerosol generating device (100) according to an embodiment may be replaced with other components, or additional components may be added to the aerosol generating device (100). For example, at least one of the components of the aerosol generating device (100) of FIG. 6 may be identical or similar to the components of the aerosol generating device (100) described with reference to FIGS. 1 to 5, and any redundant description will be omitted below.

[0186] The housing (101) may form the exterior of the aerosol generating device (100), and components of the aerosol generating device (100) may be arranged in the interior space of the housing (101). The housing (101) may include a battery receiving space (110) for receiving a battery (111). The battery receiving space (110) may be formed on one side of the housing (101) (e.g., a side facing the +x-axis). The battery receiving space (110) may be sunken toward the interior of the housing (101) to receive the battery (111). The depth of the sunken battery receiving space (110) may correspond to the thickness of the battery (111) (e.g., the length of the battery (111) in the x-axis direction).

[0187] The battery (111) can be coupled to or accommodated in the battery accommodation space (110) to supply power for the operation of components arranged in the internal space of the housing (101). The battery (111) may be formed as a rectangular cross-section (e.g., a cross-section of the battery (111) cut along the xy plane) or a square pillar with rounded corners, but is not limited thereto.

[0188] The battery cover (600) is detachably connected to the housing (101) and can protect the battery (111) accommodated in the battery accommodation space (110) from external impact or foreign substances. The battery cover (600) can open the battery accommodation space (110) when it is detachably connected to or separated from the housing (101), and the battery cover (600) can close the battery accommodation space when it is attached to or connected to the housing (101).

[0189] When the battery cover (600) is detached from the housing (101), the battery receiving space (110) can be exposed to the outside. With the battery cover (600) detached from the housing (101), a battery (111) that has reached the end of its life or requires charging can be separated from the battery receiving space (110), and a new or charged battery (111) can be coupled to the battery receiving space (110).

[0190] The battery cover (600) may include an outer battery cover (610), an inner battery cover (620), and a protrusion (630). The battery cover (600) may include one or more small holes in at least one area. For example, the battery cover (600) may include a plurality of perforations. As the plurality of perforations are arranged in the battery cover (600), the breathability of the battery accommodation space (110) may be improved. As another example, the battery cover (600) may include a mesh-shaped structure. The mesh-shaped structure may be a metal sheet. However, the present invention is not limited thereto, and the mesh-shaped structure may be a sheet including plastic or polyethylene terephthalate. As the battery cover (600) includes the mesh-shaped structure, the breathability of the battery accommodation space (110) may be improved.

[0191] The outer battery cover (610) may be placed in an area of ​​the housing (101) to form an outer surface (e.g., a surface facing the +x axis) of the battery cover (600). After the battery (111) is accommodated in the battery accommodation space (110), the outer battery cover (610) closes the battery accommodation space (110), thereby protecting the battery (111) from external impact or foreign substances.

[0192] The inner battery cover (620) may be formed at the center of the inner surface (e.g., the surface in the -x-axis direction) of the battery cover (600) and may protrude in a direction (e.g., in the -x-axis direction) toward the inside of the battery receiving space (110). When the battery (111) is received in the battery receiving space (110) and the battery cover (600) and the housing (101) are combined, the inner battery cover (620) may pressurize the battery (111) in a direction (e.g., in the -x-axis direction) toward the housing (101). As the battery (111) is pressed by the inner battery cover (620), the battery (111) may be fixed to the battery receiving space (110), and thus the battery (111) may be protected from external impact.

[0193] The protrusion (630) may be formed along the inner edge of the battery cover (600) and may protrude in a direction toward the inside of the battery receiving space (110). For example, the protrusion (630) may have a shape in which a square ring protrudes when the inner surface of the battery cover (500) is viewed in the direction toward the +x axis. The protrusion (630) may be inserted into a groove (120) formed in the housing (101) and may be fitted into the groove (120). As the protrusion (630) of the battery cover (600) is fitted into the groove (120) of the housing (101), the battery cover (600) may be coupled or fixed to the housing (101).

[0194] The second heat dissipation member (440) is positioned between the protrusion (630) and the groove (120) when the battery cover (600) is coupled to the housing (101), and can absorb heat generated inside the battery receiving space (110).

[0195] The second heat dissipation member (440) can prevent heat generated from the battery (111) from being transferred from the battery receiving space (110) to the product heater (230) and / or the cartridge heater (330), thereby preventing malfunction and / or damage to the product heater (230) and the cartridge heater (330) due to heat generated from the battery (111).

[0196] The second heat dissipation member (440) can effectively release heat generated from the battery (111), thereby minimizing external heat generation of the battery receiving space (110). The second heat dissipation member (440) can prevent users of the aerosol generating device (100) from getting burned on their hands due to heat generated from the battery (111).

[0197] Although not shown, the aerosol generating device (100) of FIG. 6 may further include a second airflow passage described with reference to FIG. 4, and the second airflow passage will be described later with reference to FIG. 8.

[0198] FIG. 7 is a drawing for explaining a second heat dissipation member of an aerosol generating device according to another embodiment. Referring to FIG. 7, an aerosol generating device (100) according to another embodiment may include a housing (101), a battery (111), a second heat dissipation member (440), and a battery cover (600). The aerosol generating device (100) of FIG. 7 may be an aerosol generating device that is different from the aerosol generating device (100) of FIG. 6 only in the shape and arrangement structure of the housing (101), the battery (111), the second heat dissipation member (440), and the battery cover (600), and any overlapping description will be omitted below.

[0199] The housing (101) may include a battery receiving space (110) for receiving a battery (111). The battery receiving space (110) may be formed on one side of the housing (101) (e.g., a side facing the -z-axis). The battery receiving space (110) may be sunken toward the inside of the housing (101) to receive the battery (111). The depth of the sunken battery receiving space (110) may correspond to the length of the battery (111) (e.g., the length of the battery (111) in the z-axis direction).

[0200] The battery (111) can be coupled to or accommodated in the battery accommodation space (110) to supply power for the operation of components arranged in the internal space of the housing (101). The battery (111) can be formed as a cylinder having a circular or oval cross-section (e.g., a cross-section of the battery (111) cut along the xy plane), but is not limited thereto.

[0201] The battery cover (600) is detachably connected to the housing (101) and can protect the battery (111) accommodated in the battery accommodation space (110) from external impact or foreign substances. The battery cover (600) may include an outer battery cover (610), an inner battery cover (620), and a protrusion (630).

[0202] The outer battery cover (610) may be arranged in an area of ​​the housing (101) to form an outer surface (e.g., a surface facing the -z-axis) of the battery cover (600). The inner battery cover (620) may be formed in the center of the inner surface (e.g., a surface facing the +z-axis) of the battery cover (600) and may protrude in a direction (e.g., a +z-axis direction) toward the inside of the battery receiving space (110). When the battery cover (600) and the housing (101) are combined after the battery (111) is received in the battery receiving space (110), the inner battery cover (620) may press the battery (111) in a direction (e.g., a +z-axis direction) toward the housing (101).

[0203] The protrusion (630) may be formed along the inner edge of the battery cover (600) and may protrude in a direction toward the inside of the battery receiving space (110). For example, the protrusion (630) may have a shape in which a circular ring protrudes when the inner surface of the battery cover (500) is viewed in the direction toward the -z axis. The protrusion (630) may be inserted into a groove (120) formed in the housing (101) and may be fitted into the groove (120). As the protrusion (630) of the battery cover (600) is fitted into the groove (120) of the housing (101), the battery cover (600) may be coupled or fixed to the housing (101).

[0204] The second heat dissipation member (440) is positioned between the protrusion (630) and the groove (120) when the battery cover (600) is coupled to the housing (101), and can absorb heat generated inside the battery receiving space (110).

[0205] The second heat dissipation member (440) can prevent heat generated from the battery (111) from being transferred from the battery receiving space (110) to the product heater (230) and / or the cartridge heater (330), thereby preventing malfunction and / or damage to the product heater (230) and the cartridge heater (330) due to heat generated from the battery (111).

[0206] The second heat dissipation member (440) can effectively release heat generated from the battery (111), thereby minimizing external heat generation of the battery receiving space (110). The second heat dissipation member (440) can prevent users of the aerosol generating device (100) from getting burned on their hands due to heat generated from the battery (111).

[0207] Although not shown, the aerosol generating device (100) of FIG. 7 may further include a second airflow passage described with reference to FIG. 4, and the second airflow passage will be described later with reference to FIGS. 9a and 9b.

[0208] Fig. 8 is a drawing for explaining the arrangement structure of the second airflow passage of Fig. 6. Fig. 8 may be a cross-sectional view of an aerosol generating device (100) of Fig. 6 in which a second airflow passage (410) and an air hole (800) are added, cut along the yz plane, and any redundant description thereof will be omitted below. In Fig. 8, arrows indicate the movement path of air (or 'outside air').

[0209] Referring to FIG. 8, the second airflow passage (410) may be positioned inside the housing (101) so that external air introduced into the battery accommodation space (110) moves along the edge of the battery accommodation space (110) and then moves back to the outside of the aerosol generating device (100). The second airflow passage (410) may be formed in a shape that is bent multiple times in a direction parallel to the longitudinal direction (e.g., z-axis direction) of the housing (101), in a vertical direction, or in a diagonal shape. As the second airflow passage (410) is formed in a more complex shape, heat generated from the battery (111) can be more efficiently released to the outside of the aerosol generating device (100), thereby minimizing external heat generation of the battery accommodation space (110).

[0210] The housing (101) may include one or more air holes (800) penetrating the housing (101). For example, the first air hole (801) and the third air hole (803) may be formed on one side of the housing (101) (e.g., the side facing the -y axis), and the second air hole (802) and the fourth air hole (804) may be formed on another side of the housing (101) (e.g., the side facing the +y axis). However, the number and arrangement of the air holes (800) are not limited thereto. For another example, the third air hole (803) and the fourth air hole (804) may be formed on another side of the housing (101) (e.g., the side facing the -z axis).

[0211] The aerosol generating device (100) can effectively release heat generated from the battery (111) by using the second airflow passage (410) and the air hole (800), thereby minimizing external heat generation of the battery receiving space (110). The aerosol generating device (100) equipped with the second airflow passage (410) and the air hole (800) can minimize external heat generation of the battery receiving space (110), thereby preventing internal components of the aerosol generating device (100) from malfunctioning and / or being damaged by heat generated from the battery (111), and can prevent users of the aerosol generating device (100) from getting burned on their hands by heat generated from the battery (111).

[0212] FIG. 9A is a drawing for explaining the arrangement structure of the second airflow passage of FIG. 7 according to an example, and FIG. 9B is a drawing for explaining the arrangement structure of the second airflow passage of FIG. 7 according to another example. FIGS. 9A and 9B may be cross-sectional views taken along the yz plane of an aerosol generating device in which a second airflow passage (410) and an air hole (800) are added to the aerosol generating device (100) of FIG. 7, and any redundant description thereof will be omitted below. In FIGS. 9A and 9B, arrows indicate the movement path of air (or 'outside air').

[0213] Referring to FIG. 9A, the second airflow passage (410) may be positioned inside the housing (101) and may be arranged so that external air introduced into the battery accommodation space (110) moves along the edge of the battery accommodation space (110) and then moves back to the outside of the aerosol generating device (100). The second airflow passage (410) may be formed in a shape that is bent multiple times in a direction parallel to the longitudinal direction (e.g., z-axis direction) of the housing (101), in a vertical direction, or in a diagonal shape. As the second airflow passage (410) is formed in a more complex shape, heat generated from the battery (111) can be more efficiently released to the outside of the aerosol generating device (100), thereby minimizing external heat generation of the battery accommodation space (110).

[0214] The housing (101) may include one or more air holes (800) penetrating the housing (101). For example, the first air hole (801) and the third air hole (803) may be formed on one side of the housing (101) (e.g., the side facing the -y-axis), the second air hole (802) and the fourth air hole (804) may be formed on another side of the housing (101) (e.g., the side facing the +y-axis), and the fifth air hole (805) and the sixth air hole (806) may be formed on another side of the housing (101) (e.g., the side facing the -z-axis). However, the number and arrangement structure of the air holes (800) are not limited thereto. As another example, three air holes may be formed on one side of the housing (101) (e.g., the side facing the -y axis) and four air holes may be formed on the other side of the housing (101) (e.g., the side facing the +y axis).

[0215] Referring to FIG. 9B, the second airflow passage (410) may be positioned inside the housing (101) and may be arranged so that external air introduced into the battery accommodation space (110) moves in a spiral direction along the outer circumference of the battery accommodation space (110) and then moves back to the outside of the aerosol generating device (100). The second airflow passage (410) may be formed in a shape that is bent multiple times in a direction parallel to the longitudinal direction (e.g., z-axis direction) of the housing (101), in a vertical direction, or in a diagonal shape. As the second airflow passage (410) is formed in a more complex shape, heat generated from the battery (111) can be more efficiently released to the outside of the aerosol generating device (100), thereby minimizing external heat generation of the battery accommodation space (110).

[0216] The housing (101) may include one or more air holes (800) penetrating the housing (101). For example, a seventh air hole (807) may be formed on one side of the housing (101) (e.g., a side facing the -y-axis), an eighth air hole (808) may be formed on another side of the housing (101) (e.g., a side facing the +y-axis), and a ninth air hole (809) and a tenth air hole (810) may be formed on another side of the housing (101) (e.g., a side facing the -z-axis). However, the number and arrangement structure of the air holes (800) are not limited thereto.

[0217] The aerosol generating device (100) can effectively release heat generated from the battery (111) by using the second airflow passage (410) and the air hole (800), thereby minimizing external heat generation of the battery receiving space (110). The aerosol generating device (100) equipped with the second airflow passage (410) and the air hole (800) can minimize external heat generation of the battery receiving space (110), thereby preventing internal components of the aerosol generating device (100) from malfunctioning and / or being damaged by heat generated from the battery (111), and can prevent users of the aerosol generating device (100) from getting burned on their hands by heat generated from the battery (111).

[0218] Figure 10 is a block diagram of an aerosol generating device according to another embodiment.

[0219] The aerosol generator (1) may include a power source (11), a control unit (12), a sensor (13), an output unit (14), an input unit (15), a communication unit (16), a memory (17), and at least one heater (18, 24). However, the internal structure of the aerosol generator (1) is not limited to that shown in Fig. 1. That is, a person having ordinary skill in the art related to the present embodiment will understand that some of the components shown in Fig. 1 may be omitted or new components may be added depending on the design of the aerosol generator (1).

[0220] The sensor (13) can detect the status of the aerosol generator (1) or the status around the aerosol generator (1) and transmit the detected information to the control unit (12). Based on the detected information, the control unit (12) can control the aerosol generator (1) so that various functions such as controlling the operation of the cartridge heater (24) and / or heater (18), restricting smoking, determining whether a stick (S) and / or cartridge (19) is inserted, and displaying a notification are performed.

[0221] The sensor (13) may include at least one of a temperature sensor (1031), a puff sensor (1032), an insertion detection sensor (1033), a reuse detection sensor (1034), a cartridge detection sensor (1035), a cap detection sensor (1036), and a movement detection sensor (1037).

[0222] The temperature sensor (1031) can detect the temperature at which the cartridge heater (24) and / or the heater (18) is heated. The aerosol generator (1) may include a separate temperature sensor that detects the temperature of the cartridge heater (24) and / or the heater (18), or the cartridge heater (24) and / or the heater (18) itself may serve as the temperature sensor.

[0223] The temperature sensor (1031) can output a signal corresponding to the temperature of the cartridge heater (24) and / or the heater (18). For example, the temperature sensor (1031) can include a resistance element whose resistance value changes in response to a change in the temperature of the cartridge heater (24) and / or the heater (18). It can be implemented by a thermistor, which is an element that utilizes the property of changing resistance depending on temperature. At this time, the temperature sensor (1031) can output a signal corresponding to the resistance value of the resistance element as a signal corresponding to the temperature of the cartridge heater (24) and / or the heater (18). For example, the temperature sensor (1031) can be configured as a sensor that detects the resistance value of the cartridge heater (24) and / or the heater (18). At this time, the temperature sensor (1031) can output a signal corresponding to the resistance value of the cartridge heater (24) and / or heater (18) as a signal corresponding to the temperature of the cartridge heater (24) and / or heater (18).

[0224] A temperature sensor (1031) may be placed around the power source (11) to monitor the temperature of the power source (11). The temperature sensor (1031) may be placed adjacent to the power source (11). For example, the temperature sensor (1031) may be attached to one side of a battery, which is the power source (11). For example, the temperature sensor (1031) may be mounted on one side of a printed circuit board.

[0225] A temperature sensor (1031) is placed inside the body (10) and can detect the internal temperature of the body (10).

[0226] The puff sensor (1032) can detect a user's puff based on various physical changes in the airflow path. The puff sensor (1032) can output a signal corresponding to the puff. For example, the puff sensor (1032) can be a pressure sensor. The puff sensor (1032) can output a signal corresponding to the internal pressure of the aerosol generating device. Here, the internal pressure of the aerosol generating device (1) can correspond to the pressure of the airflow path through which the gas flows. The puff sensor (1032) can be arranged in correspondence to the airflow path through which the gas flows in the aerosol generating device (1).

[0227] The insertion detection sensor (1033) can detect insertion and / or removal of the stick (S). The insertion detection sensor (1033) can detect a signal change according to the insertion and / or removal of the stick (S). The insertion detection sensor (1033) can be installed around the insertion space. The insertion detection sensor (1033) can detect the insertion and / or removal of the stick (S) according to a change in the permittivity inside the insertion space. For example, the insertion detection sensor (1033) can be an inductive sensor and / or a capacitance sensor.

[0228] An inductive sensor may include at least one coil. The coil of the inductive sensor may be positioned adjacent to an insertion space. For example, when a magnetic field changes around a current-flowing coil, the characteristics of the current flowing in the coil may change according to Faraday's law of electromagnetic induction. Here, the characteristics of the current flowing in the coil may include the frequency of the alternating current, the current value, the voltage value, the inductance value, the impedance value, etc.

[0229] An inductive sensor can output a signal corresponding to the characteristics of the current flowing through the coil. For example, an inductive sensor can output a signal corresponding to the inductance value of the coil.

[0230] A capacitance sensor may include a conductor. The conductor of the capacitance sensor may be positioned adjacent to the insertion space. The capacitance sensor may output a signal corresponding to the electromagnetic properties of the surroundings, for example, the electrostatic capacitance around the conductor. For example, when a stick (S) including a wrapper made of a metallic material is inserted into the insertion space, the electromagnetic properties around the conductor may be changed by the wrapper of the stick (S).

[0231] A reuse detection sensor (1034) can detect whether the stick (S) has been reused. The reuse detection sensor (1034) may be a color sensor. The color sensor can detect the color of the stick (S). The color sensor can detect the color of a portion of a wrapper that wraps the outside of the stick (S). The color sensor can detect a value for an optical characteristic corresponding to the color of an object based on light reflected from the object. For example, the optical characteristic may be a wavelength of light. The color sensor may be implemented as a single component with the proximity sensor, or may be implemented as a separate component distinct from the proximity sensor.

[0232] At least some of the wrappers constituting the stick (S) may change color due to the aerosol. The reuse detection sensor (1034) may be positioned corresponding to a position where at least some of the wrappers that change color due to the aerosol are disposed when the stick (S) is inserted into the insertion space. For example, before the stick (S) is used by a user, the color of at least some of the wrappers may be a first color. At this time, as at least some of the wrappers are wetted by the aerosol generated by the aerosol generating device (1) while passing through the stick (S), the color of at least some of the wrappers may change to a second color. Meanwhile, the color of at least some of the wrappers may be maintained at the second color after changing from the first color to the second color.

[0233] The cartridge detection sensor (1035) can detect the mounting and / or removal of the cartridge (19). The cartridge detection sensor (1035) can be implemented by an inductance-based sensor, a capacitive sensor, a resistance sensor, a Hall sensor (hall IC) using the Hall effect, etc.

[0234] The cap detection sensor (1036) can detect the attachment and / or removal of the cap. When the cap is separated from the body (10), the cartridge (19) and a portion of the body (10) covered by the cap may be exposed to the outside. The cap detection sensor (1036) can be implemented by a contact sensor, a hall sensor (hall IC), an optical sensor, or the like.

[0235] A motion detection sensor (1037) can detect the movement of the aerosol generating device. The motion detection sensor (1037) can be implemented with at least one of an acceleration sensor and a gyro sensor.

[0236] In addition to the sensors (131 to 137) described above, the sensor (13) may further include at least one of a humidity sensor, a pressure sensor, a magnetic sensor, a position sensor (GPS), and a proximity sensor. Since the functions of each sensor can be intuitively inferred by a person skilled in the art from its name, a detailed description thereof may be omitted.

[0237] The output unit (14) can output information on the status of the aerosol generator (1) and provide it to the user. The output unit (14) may include at least one of a display (1041), a haptic unit (1042), and an audio output unit (1043), but is not limited thereto. When the display (1041) and the touch pad form a layered structure to form a touch screen, the display (1041) can be used as an input device in addition to an output device.

[0238] The display (1041) can visually provide information about the aerosol generator (1) to the user. For example, the information about the aerosol generator (1) may refer to various information such as the charging / discharging status of the power supply (11) of the aerosol generator (1), the preheating status of the heater (18), the insertion / removal status of the stick (S) and / or cartridge (19), the mounting / removal status of the cap, or the status in which the use of the aerosol generator (1) is restricted (e.g., detection of an abnormal item), and the display (1041) can output the above information to the outside. For example, the display (1041) may be in the form of an LED light-emitting element. For example, the display (1041) may be a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), etc.

[0239] The haptic unit (1042) can provide tactile information about the aerosol generator (1) to the user by converting an electrical signal into a mechanical stimulus or an electrical stimulus. For example, the haptic unit (1042) can generate a vibration corresponding to the completion of the initial preheating when the initial power is supplied to the cartridge heater (24) and / or heater (18) for a set period of time. The haptic unit (1042) can include a vibration motor, a piezoelectric element, or an electrical stimulation device.

[0240] The acoustic output unit (1043) can provide information about the aerosol generator (1) to the user audibly. For example, the acoustic output unit (1043) can convert an electrical signal into an acoustic signal and output it to the outside.

[0241] The power source (11) can supply power used to operate the aerosol generator (1). The power source (11) can supply power so that the cartridge heater (24) and / or the heater (18) can be heated. In addition, the power source (11) can supply power required for the operation of other components provided in the aerosol generator (1), such as a sensor (13), an output unit (14), an input unit (15), a communication unit (16), and a memory (17). The power source (11) can be a rechargeable battery or a disposable battery. For example, the power source (11) can be a lithium polymer (LiPoly) battery, but is not limited thereto.

[0242] Although not shown in FIG. 1, the aerosol generator (1) may further include a power protection circuit. The power protection circuit may be electrically connected to a power source (11) and include a switching element.

[0243] The power protection circuit can block the power supply (11) according to certain conditions. For example, the power protection circuit can block the power supply (11) when the voltage level of the power supply (11) is higher than a first voltage corresponding to overcharge. For example, the power protection circuit can block the power supply (11) when the voltage level of the power supply (11) is lower than a second voltage corresponding to overdischarge.

[0244] The heater (18) can receive power from the power source (11) and heat the medium or aerosol generating material within the stick (S). Although not illustrated in FIG. 10, the aerosol generating device (1) may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power of the power source (11) and supplies it to the cartridge heater (24) and / or the heater (18). In addition, when the aerosol generating device (1) generates the aerosol by induction heating, the aerosol generating device (1) may further include a DC / AC converter that converts the direct current power of the power source (11) into alternating current power.

[0245] The control unit (12), sensor (13), output unit (14), input unit (15), communication unit (16), and memory (17) can receive power from the power source (11) and perform their functions. Although not shown in FIG. 1, a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, which converts the power of the power source (11) and supplies it to each component may be further included. In addition, although not shown in FIG. 10, a noise filter may be provided between the power source (11) and the heater (18). The noise filter may be a low pass filter. The low pass filter may include at least one inductor and a capacitor. The cutoff frequency of the low pass filter may correspond to the frequency of the high frequency switching current applied from the power source (11) to the heater (18). The low pass filter can prevent high frequency noise components from being applied to a sensor (13), such as an insertion detection sensor (1033).

[0246] In one embodiment, the cartridge heater (24) and / or heater (18) may be formed of any suitable electrically resistive material. For example, suitable electrically resistive materials may be metals or metal alloys including, but not limited to, titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, nichrome, and the like. Additionally, the heater (18) may be implemented as, but not limited to, a metal heating wire, a metal heating plate having electrically conductive tracks arranged thereon, a ceramic heating element, and the like.

[0247] In another embodiment, the heater (18) may be an induction heater. For example, the heater (18) may include a susceptor that heats the aerosol generating material by generating heat through a magnetic field applied by a coil.

[0248] The input unit (15) can receive information input from a user or output information to the user. For example, the input unit (15) can be a touch panel. The touch panel can include at least one touch sensor that detects touch. For example, the touch sensor can include, but is not limited to, a capacitive touch sensor, a resistive touch sensor, a surface acoustic wave touch sensor, an infrared touch sensor, etc.

[0249] The display (1041) and the touch panel may be implemented as a single panel. For example, the touch panel may be inserted into the display (1041) (on-cell type or in-cell type). For example, the touch panel may be added on to the display (1041) (add-on type).

[0250] Meanwhile, the input unit (15) may include, but is not limited to, buttons, key pads, dome switches, jog wheels, jog switches, etc.

[0254] The wireless communication unit may include, but is not limited to, a cellular network communication unit, an Internet communication unit, a computer network (e.g., a LAN or WAN) communication unit, etc.

[0255] Although not shown in FIG. 1, the aerosol generator (1) further includes a connection interface such as a USB (universal serial bus) interface, and can transmit and receive information or charge a power source (11) by connecting to another external device through a connection interface such as a USB interface.

[0256] The control unit (12) can control the overall operation of the aerosol generator (1). In one embodiment, the control unit (12) may include at least one processor. The processor may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Furthermore, it will be understood by those skilled in the art to which the present embodiment pertains that the processor may be implemented as other types of hardware.

[0257] The control unit (12) can control the temperature of the heater (18) by controlling the supply of power from the power source (11) to the heater (18). The control unit (12) can control the temperature of the cartridge heater (24) and / or the heater (18) based on the temperature of the cartridge heater (24) and / or the heater (18) sensed by the temperature sensor (1031). The control unit (12) can adjust the power supplied to the cartridge heater (24) and / or the heater (18) based on the temperature of the cartridge heater (24) and / or the heater (18). For example, the control unit (12) can determine a target temperature for the cartridge heater (24) and / or the heater (18) based on a temperature profile stored in the memory (17).

[0258] The aerosol generator (1) may include a power supply circuit (not shown) electrically connected to the power supply (11) between the power supply (11) and the cartridge heater (24) and / or the heater (18). The power supply circuit may be electrically connected to the cartridge heater (24), the heater (18), or the induction coil (181). The power supply circuit may include at least one switching element. The switching element may be implemented by a bipolar junction transistor (BJT), a field effect transistor (FET), or the like. The control unit (12) may control the power supply circuit.

[0259] The control unit (12) can control power supply by controlling the switching of the switching elements of the power supply circuit. The power supply circuit may be an inverter that converts direct current power output from the power source (11) into alternating current power. For example, the inverter may be configured as a full-bridge circuit or a half-bridge circuit including a plurality of switching elements.

[0260] The control unit (12) can turn on the switching element so that power is supplied from the power source (11) to the cartridge heater (24) and / or the heater (18). The control unit (12) can turn off the switching element so that power is cut off to the cartridge heater (24) and / or the heater (18). The control unit (12) can control the current supplied from the power source (11) by controlling the frequency and / or duty ratio of the current pulse input to the switching element.

[0261] The control unit (12) can control the voltage output from the power source (11) by controlling the switching of the switching element of the power supply circuit. The power conversion circuit can convert the voltage output from the power source (11). For example, the power conversion circuit can include a buck converter that steps down the voltage output from the power source (11). For example, the power conversion circuit can be implemented using a buck-boost converter, a zener diode, etc.

[0262] The control unit (12) can control the on / off operation of the switching element included in the power conversion circuit to adjust the level of the voltage output from the power conversion circuit. When the on state of the switching element continues, the level of the voltage output from the power conversion circuit may correspond to the level of the voltage output from the power source (11). The duty ratio for the on / off operation of the switching element may correspond to the ratio of the voltage output from the power conversion circuit to the voltage output from the power source (11). As the duty ratio for the on / off operation of the switching element decreases, the level of the voltage output from the power conversion circuit may decrease. The heater (18) can be heated based on the voltage output from the power conversion circuit.

[0263] The control unit (12) can control power to be supplied to the heater (18) using at least one of the pulse width modulation (PWM) method and the proportional-integral-differential (PID) method.

[0264] For example, the control unit (12) can control a current pulse having a predetermined frequency and duty ratio to be supplied to the heater (18) using the PWM method. The control unit (12) can control the power supplied to the heater (18) by adjusting the frequency and duty ratio of the current pulse.

[0265] For example, the control unit (12) can determine a target temperature that is the target of control based on a temperature profile. The control unit (12) can control the power supplied to the heater (18) by using the PID method, which is a feedback control method using a difference value between the temperature of the heater (18) and the target temperature, a value obtained by integrating the difference value over time, and a value obtained by differentiating the difference value over time.

[0266] The control unit (12) can prevent the cartridge heater (24) and / or the heater (18) from overheating. For example, the control unit (12) can control the operation of the power conversion circuit so that the supply of power to the cartridge heater (24) and / or the heater (18) is cut off based on the temperature of the cartridge heater (24) and / or the heater (18) exceeding a preset limit temperature. For example, the control unit (12) can reduce the amount of power supplied to the cartridge heater (24) and / or the heater (18) by a certain percentage based on the temperature of the cartridge heater (24) and / or the heater (18) exceeding a preset limit temperature. For example, the control unit (12) can determine that the aerosol generating substance contained in the cartridge (19) is exhausted based on the temperature of the cartridge heater (24) exceeding the limit temperature, and can cut off the supply of power to the cartridge heater (24).
