Description

Technical Field

[0001] The present invention relates to an aerosol generating device including a detachable battery.

Background Art

[0002] Recently, the demand for alternative methods to overcome the disadvantages of conventional cigarettes has been increasing. For example, there is an increasing demand for a system that generates an aerosol by heating a cigarette (or "aerosol generating article") using an aerosol generating device, rather than a method of generating an aerosol by burning a cigarette.

[0003] An aerosol generating device includes a battery for power supply and a heater that generates heat by power supply, and can generate an aerosol by heating an aerosol generating substance through the heater. In particular, the aerosol generating device uses an integrated battery for miniaturization of the device, but recently, research on an aerosol generating device using a detachable battery to increase user convenience has been actively conducted.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The battery of the aerosol generating device can generate heat during use or charging. In particular, when the battery of the aerosol generating device deteriorates or is exposed to an external impact and its durability weakens, abnormal overheating occurs from the battery of the aerosol generating device.

[0005] Due to such a heat generation phenomenon, internal components of the aerosol generating device may malfunction or malfunction, and a situation may occur where a user using the aerosol generating device gets burned. In addition, there is a problem that the temperature of the aerosol generated by the aerosol generating device is not cooled to a temperature suitable for inhalation.

[0006] Various embodiments of the present invention aim to prevent malfunction or damage to an aerosol generator and to prevent deterioration of the aerosol generator's performance due to heat generated from the battery of the aerosol generator.

[0031] The embodiments disclosed herein will be described in detail below with reference to the attached drawings, but regardless of the reference numerals used in the drawings, identical or similar components will be given the same reference numerals, and redundant descriptions thereof will be omitted.

[0032] Figure 1 is a perspective view of an aerosol generating apparatus according to one embodiment.

[0033] The aerosol generating device 100 can generate and provide aerosols.

[0034] Referring to Figure 1, an aerosol generator 100 according to one embodiment may include a housing 101. The housing 101 forms the overall exterior of the aerosol generator 100 and may contain internal space. Various components for generating and providing aerosols may be arranged in the internal space (or "packaging space") of the housing 101.

[0035] The housing 101 may include a first containment space 210 into which the aerosol product 200 is inserted, a cover 102 for opening or closing the first containment space 210, and a battery containment space 110 for housing the battery 111.

[0036] The first containment space 210 can provide a space into which the aerosol product 200 is detachably inserted (or "bound"). The aerosol product 200 may include an aerosol-generating substance that is heated by a heater to produce an aerosol. The first containment space 210 can provide a space that is open toward the outside of the housing 101 so that the aerosol product 200 can be inserted.

[0037] The first containment space 210 may be recessed toward the interior of the housing 101 so that at least a portion of the aerosol product 200 can be inserted into it. The recessed depth of the first containment space 210 may correspond to the length of the region in the aerosol product 200 that contains the aerosol-generating substance and / or medium. A portion of the aerosol product 200 may be inserted toward the interior of the housing 101, while another portion of the aerosol product 200 may protrude toward the exterior of the housing 101. A user may put the portion of the aerosol product 200 exposed toward the exterior of the housing 101 into their mouth and inhale the air containing the aerosol.

[0038] The cover 102 can open or close the first containment space 210. The cover 102 is movably positioned on the housing 101 and can either expose the first containment space 210 to the outside of the aerosol generator 100 or cover the first containment space 210 so that it is not exposed to the outside of the aerosol generator 100. When the cover 102 is positioned in the first region of the housing 101, it can open the first containment space 210 into which the aerosol product 200 can be inserted. The cover 102 can move from the first region to the second region of the housing 101 to close the first containment space 210. By positioning the cover 102 in the second region of the housing 101 and not exposing the first containment space 210 to the outside, the first containment space 210 can be protected from external impacts or external foreign matter.

[0039] The battery housing space 110 can accommodate a battery 111 for supplying power to a heater for heating the aerosol product 200. The battery housing space 110 is formed on one side of the housing 101 (for example, the side facing the +x axis) and can accommodate the battery 111. The location where the battery housing space 110 is formed is not limited to this, and the battery housing space 110 may be formed in an internal area of ​​the housing 101.

[0040] The battery 111 is detachably coupled to the battery housing space 110 and can supply power for the operation of the components of the aerosol generator 100. The battery 111 housed in the battery housing space 110 is coupled to the battery housing space 110 and can be electrically connected to the components of the aerosol generator 100 (e.g., heater, processor).

[0041] For example, the battery housing space 110 may have terminals for electrically connecting to the battery 111, and the battery 111 may have terminals for supplying power to the aerosol generator 100 through the terminals provided in the battery housing space 110. The battery 111 can supply power for the operation of the components of the aerosol generator 100 through the terminals provided in the battery 111 and the terminals provided in the battery housing space 110.

[0042] The battery 111 can be charged while attached to the battery housing space 110 and / or while detached from the battery housing space 110. With the battery 111 housed in the battery housing space 110, the aerosol generator 100 is electrically connected to an external charger, and power supplied from the external charger is supplied to the battery 111 through terminals provided in the battery housing space 110 and terminals provided on the battery 111, thereby charging the battery 111. The charging method for the battery 111 is not limited to this. The battery 111 can be detached from the battery housing space 110 and connected to an external charger independently of the aerosol generator 100, or housed in the external charger. The battery 111 can be charged by power supplied from an external charger through terminals provided on the battery 111.

[0043] When the battery 111 is charged or used, heat is generated from the battery 111. The heat generated from the battery 111 affects the performance of other components of the aerosol generator 100 (e.g., heaters, processors, etc.) located around the battery 111. In particular, if the battery 111 is overcharged or over-discharged, overheating occurs from the battery 111, which can cause malfunction and / or damage to other components of the aerosol generator 100 located around the battery 111.

[0044] As the battery 111 is used, its chemical and / or physical properties deteriorate. For example, as the battery 111 is used, its internal resistance increases and its usable capacity decreases. A battery 111 that has reached the end of its life needs to be replaced with a new battery 111 at any given time. A battery 111 that has reached the end of its life can be passively and / or automatically detached from the aerosol generator 100, and a new battery 111 can be newly attached to the aerosol generator 100.

[0045] Overheating occurs from a battery 111 that has reached the end of its lifespan or has been subjected to external shock. If the battery 111 deteriorates or is subjected to external shock, the durability of the battery 111 is weakened. A battery 111 with weakened durability will operate abnormally, and abnormal overheating will occur from the battery 111. Overheating generated from a deteriorated or externally shocked battery 111 will cause malfunction and / or damage to other components of the aerosol generator 100 located around the battery 111.

[0046] Although not shown, the aerosol generator 100 may further include a battery cover detachably coupled to the housing 101 to protect the battery 111. With the battery cover detached from the housing 101, the battery housing space 110 and at least a portion of the battery may be exposed to the outside of the aerosol generator 100. Through the open battery housing space 110, an expired battery 111 can be replaced with a new one. The battery cover can be attached to the housing 101 to close the battery housing space 110. The battery 111 housed in the closed battery housing space 110 is protected from external foreign matter and can be secured inside the battery housing space 110 by the battery cover. The aerosol generator 100 may further include fixing members positioned in the battery housing space 110 and / or the battery cover for securing the battery 111 to the battery housing space 110. The aerosol generator 100 can prevent the battery 111 from being easily separated from the aerosol generator 100 by external physical impact by using a fixing member to secure the battery 111 in the battery housing space 110.

[0047] Figures 2A to 2E are various examples illustrating the configuration of the aerosol generator shown in Figure 1. Referring to Figures 2A to 2E, the aerosol generator 100 may include a battery 111, a processor 130, and heaters 120a to 120e. The components of the aerosol generator 100 are identical or similar to at least one of the components of the aerosol generator 100 shown in Figures 1 to 2, and redundant explanations will be omitted below.

[0048] The aerosol generator 100 can be embodied in a variety of ways. For example, the aerosol generator 100 can utilize an electric resistance heating method or an induction heating method. As another example, the aerosol generator 100 may be embodied further to include a vaporizer or a cartridge. Figures 2A to 2E disclose components of the aerosol generator 100 relating to embodiments of the present invention, and a person with ordinary skill in the art relating to embodiments of the present invention will understand that the aerosol generator 100 may further include components other than those shown in Figures 2A to 2E.

[0049] Figure 2A is a diagram illustrating an example of an electrical resistance type aerosol generator 100. Referring to Figure 2A, the aerosol generator 100 may include a battery 111, a heater 120a, and a processor 130.

[0050] An aerosol product 200 can be inserted into the internal containment space of the aerosol generator 100 (for example, the first containment space 210 in Figure 1). Once the aerosol product 200 is inserted into the aerosol generator 100, the aerosol generator 100 can generate an aerosol from the aerosol product 200 by heating it using the heater 120a. The generated aerosol is transmitted to the user through the aerosol product 200, so the user can inhale the aerosol product 200.

[0051] Heater 120a can be heated by power supplied from battery 111. Heater 120a is an electrical resistive heater. For example, heater 120a includes a conductive track, and heater 120a can be heated by current flowing through the conductive track.

[0052] The conductive track of the heater 120a is made of an electrically resistive material, the heating temperature is determined by the power consumption of the resistor, and the resistance value of the conductive track can be set based on the power consumption of the resistor of the conductive track. The resistance value of the conductive track can be set in various ways depending on the constituent material, length, width, thickness, or pattern of the electrically resistive material.

[0053] Due to its temperature coefficient of resistance characteristic, the internal resistance of a conductive track increases as the temperature rises. For example, the temperature and resistance of a conductive track can be proportional within a given temperature range. Utilizing this principle, a heater 120a made of a conductive track can heat the aerosol product 200 using an electrical resistance method.

[0054] Conductive tracks can be made from tungsten, gold, platinum, silver, copper, nickel-palladium, or combinations thereof. Conductive tracks may also be doped with appropriate doping materials and may include alloys.

[0055] The heater 120a can be manufactured in various shapes, such as tubular, plate-shaped, needle-shaped, or rod-shaped. Multiple heaters 120a may also be arranged. The heater 120a can be inserted into the aerosol product 200 and used in an internal heating method to heat the inside of the aerosol product 200.

[0056] The battery 111 may be separated from or attached to the aerosol generator 100. When the battery 111 is attached to the aerosol generator 100, power is supplied from the battery 111 to the heater 120a for heating operation, and the temperature of the conductive track may be controlled.

[0057] 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 product 200 is heated by the heater 120a using a temperature profile.

[0058] Figures 2B and 2C are diagrams illustrating an aerosol generator 100 further equipped with vaporizers 125b and 125c as an example. Referring to Figures 2B and 2C, the aerosol generator 100 is the aerosol generator 100 of Figure 2A, further including vaporizers 125b and 125c.

[0059] Figure 2B shows that the steamer 125b and heater 120b are arranged in a single line, while Figure 2C shows that the steamer 125c and heater 120c are arranged in parallel. In other words, the aerosol generator 100 can be distinguished by the arrangement of the steamers 125b and 125c.

[0060] Heaters 120b and 120c may be heated by power supplied from battery 111. Heaters 120b and 120c are electrically resistive heaters and may include, for example, conductive tracks.

[0061] Unlike heater 120a in Figure 2A, heaters 120b and 120c in Figures 2B and 2C can be implemented as an external heating method, where heaters are placed on the outer periphery of the aerosol product 200 and heat the outer surface of the aerosol product 200.

[0062] The vaporizers 125b and 125c heat the liquid composition to generate an aerosol, which can then be transmitted to the user through the aerosol product 200. That is, the aerosol generated by the vaporizers 125b and 125c is transported along the airflow passage of the aerosol generator 100, and the airflow passage may be configured so that the aerosol generated by the vaporizers 125b and 125c is transmitted to the user through the aerosol product 200.

[0063] The vaporizers 125b and 125c may include a liquid storage unit, a liquid transfer means, and a heating element (or vaporization element). However, each of the liquid storage unit, liquid transfer means, and heating element may be an independent module and located at another location within the aerosol generator 100, not inside the vaporizers 125b and 125c.

[0064] The liquid storage section can store liquid compositions. For example, the liquid composition may be a liquid containing tobacco-containing substances, including volatile tobacco flavor components, or a liquid containing non-tobacco substances. The liquid storage section may be manufactured to detach from / attach to the vaporizers 125b, 125c, or it may be manufactured integrally with the vaporizers 125b, 125c. For example, the liquid composition may include water, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. The liquid composition may also include aerosol-forming agents such as glycerin and propylene glycol.

[0065] The liquid transfer means can transfer the liquid composition of the liquid storage section to the heating element. For example, the liquid transfer means may be a wick made of cotton fibers, ceramic fibers, glass fibers, or porous ceramic, but is not limited to these.

[0066] The heating elements provided within the vaporizers 125b and 125c are for heating (vaporizing) the liquid composition transmitted by the liquid transmission means. For example, the heating elements may be metal heating wires, metal heating plates, ceramic heaters, etc., but are not limited to these. Alternatively, the heating elements may consist of conductive filaments such as nichrome wire and be arranged in a structure that is wound around the liquid transmission means. The heating elements are heated by an electric current supply, and heat is transferred to the liquid composition in contact with the heating elements, thereby heating the liquid composition. As a result, an aerosol may be generated. For this reason, the vaporizers 125b and 125c may also be referred to by other terms such as cartomizer or atomizer.

[0067] The battery 111 may be separated from or attached to the aerosol generator 100. When the battery 111 is attached to the aerosol generator 100, power may be supplied from the battery 111 to the heaters 120b, 120c and the vaporizers 125b, 125c for heating operation.

[0068] The processor 130 can control the heating operation of the heaters 120b, 120c and the vaporizers 125b, 125c by controlling the power supplied to them. For example, the processor 130 can control the heating temperature of the aerosol product 200 by the heaters 120b, 120c and the vaporizers 125b, 125c using a temperature profile.

[0069] Figure 2D is a diagram illustrating an example of an induction heating type aerosol generator 100. Referring to Figure 2D, the aerosol generator 100 may include a heater 120d including a coil 121d and a susceptor 122d, a battery 111, and a processor 130.

[0070] The aerosol generator 100 can generate aerosols by heating the aerosol product 200 contained within the aerosol generator 100 using an induction heating method. The induction heating method refers to a method of heating a magnetic material that generates heat due to an external magnetic field by applying an alternating magnetic field that periodically changes direction. Therefore, the aerosol generator 100 can heat the aerosol product 200 by causing the magnetic material to release thermal energy by applying an alternating magnetic field to it, and then transferring the thermal energy released from the magnetic material to the aerosol product 200. Here, the magnetic material that generates heat due to an external magnetic field is a susceptor 122d. The susceptor 122d is provided in the aerosol generator 100. Alternatively, instead of being provided in the aerosol generator 100, the susceptor 122d may be provided inside the aerosol product 200 in the form of a section, thin section, strip, etc.

[0071] The susceptor 122d is made of a ferromagnetic material. For example, the material of the susceptor 122d may include metal or carbon. The material of the susceptor 122d may include at least one of ferrite, ferromagnetic alloy, stainless steel, and aluminum (Al). In addition, the material of the susceptor 122d may include at least one of ceramics such as graphite and zirconia, transition metals such as nickel (Ni) and cobalt (Co), and metalloids such as boron (B) and phosphorus (P).

[0072] The aerosol generator 100 can accommodate the aerosol product 200. The aerosol generator 100 may have a space for accommodating the aerosol product 200. A susceptor 122d may be positioned around the space for accommodating the aerosol product 200. For example, the susceptor 122d may have a cylindrical shape that surrounds the outside of the aerosol product 200. Therefore, when the aerosol product 200 is accommodated in the aerosol generator 100, the aerosol product 200 is housed in the accommodation space of the susceptor 122d, and the susceptor 122d may be positioned to surround at least a portion of the outer surface of the aerosol product 200. However, the shape of the susceptor 122d is not limited to this and can be diverse.

[0073] The heater 120d uses an induction heating method and can heat the aerosol product 200 contained in the aerosol generating device 100 by utilizing a susceptor 122d that generates heat in response to an external magnetic field generated by the coil 121d.

[0074] The coil 121d is arranged to be wound along the outer surface of the susceptor 122d, and an alternating magnetic field can be applied to the susceptor 122d. When power is supplied to the coil 121d from the aerosol generator 100, a magnetic field can be formed in the 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. If the susceptor 122d is located inside the coil 121d and is exposed to an alternating magnetic field that changes direction periodically, the susceptor 122d may generate heat, and the cigarette housed in the susceptor 122d may be heated. The shape of the coil 121d is cylindrical, wound along the longitudinal direction of the aerosol product 200, but is not limited thereto, and the coil 121d may be embodied in various types, such as a planar coil.

[0075] The battery 111 can be separated from or attached to the aerosol generator 100. When the battery 111 is attached to the aerosol generator 100, it can, for example, supply power to the coil 121d for the heating operation of the heater 120d.

[0076] The processor 130 can control the heating operation of the heater 120d by controlling the power supplied to the coil 121d. For example, the processor 130 can control the heating temperature of the aerosol product 200 by inductive heating of the susceptor 122d by adjusting the strength of the magnetic field induced by the coil 121d using a temperature profile.

[0077] Figure 2E is a diagram illustrating an aerosol generating device 100 equipped with a replaceable cartridge 210e containing an aerosol generating substance 200e, as an example.

[0078] The aerosol generator 100 in Figure 2E includes a cartridge 210e containing an aerosol generating substance 200e and a main body 220e that supports the cartridge 210e. The hardware configuration included in the aerosol generator 100 in Figure 1 can be divided and located as the main body 220e and the cartridge 210e.

[0079] Cartridge 210e can be attached to the main body 220e with the aerosol-generating substance 200e contained inside. Cartridge 210e can be attached to the main body 220e by inserting a portion of it into the receptacle of the main body 220e.

[0080] Cartridge 210e contains, but is not limited to, a liquid aerosol-generating substance 200e, which may be in any one state such as solid, gas, or gel. For example, the liquid composition may be a liquid containing a tobacco-containing substance that includes volatile tobacco flavor components, or a liquid containing a non-tobacco substance.

[0081] The heater 120e located inside the cartridge 210e performs a heating operation in response to an electrical signal or wireless signal transmitted from the main unit 220e. As a result, the aerosol-generating substance 200e inside the cartridge 210e is vaporized by the heating of the heater 120e, thereby generating an aerosol.

[0082] The heater 120e generates heat through electrical resistance to heat the aerosol-generating substance transmitted to the liquid transfer means. It is embodied in conductive filaments of metal materials such as copper, nickel, or tungsten, or ceramic heating elements, and may be wound around the liquid transfer means or positioned adjacent to the liquid transfer means.

[0083] The battery 111 may be separated from or attached to the aerosol generator 100. When the battery 111 is attached to the aerosol generator 100, power may be supplied from the battery 111 to the heater 120e for heating operation.

[0084] The processor 130 can control the heating operation of the heater 120e by controlling the power supplied to the heater 120e. For example, the processor 130 can control the heating temperature of the aerosol-generating substance 200e by the heater 120e using a temperature profile.

[0085] The aerosol generating device 100 is embodied in at least one of the aerosol generating devices 100 shown in Figures 2A to 2E, but is not necessarily limited to this and can be embodied in other ways.

The sensor housing portion B156 can cover and tightly seal the first sensor B161.

[0146] This prevents failure of the substrate or sensor due to foreign matter, aerosols discharged around the opening of pipe B130, or foreign matter passing through the first sensing hole B144.

[0147] Figure 4 is a cross-sectional view illustrating the first heat dissipation member, first airflow passage, and second airflow passage of an aerosol generating device according to one embodiment.

[0148] Referring to Figure 4, an aerosol generator 100 according to one embodiment may include a housing 101, a first containment space 210, a second containment space 310, a battery containment space 110, a first heat dissipation member 420, a first airflow passage 400, and a second airflow passage 410. The components of the aerosol generator 100 according to one embodiment are identical or similar to at least one of the components of the aerosol generator 100 in Figures 1, 2A to 2B, and 3A to 3F, and redundant explanations will be omitted below. In Figure 4, solid arrows indicate airflow, and dotted arrows indicate aerosol flow.

[0149] The housing 101 may include a first housing space 210 for housing the aerosol product 200, a second housing space 310 for housing the cartridge 300, and a battery housing space 110 for housing the battery 111.

[0150] The housing 101 forms the overall appearance of the aerosol generator 100, and components of the aerosol generator 100 may be arranged in the internal space of the housing 101. For example, a first accommodation space 210, a second accommodation space 310, and a battery accommodation space 110 may be arranged inside the housing 101. However, it is not limited to this, and as another example, a battery and a processor may be further arranged inside the housing 101.

[0151] At least a portion of the aerosol product 200 may be inserted into the first containment space 210. The length of the aerosol product 200 inserted into the first containment space 210 may correspond to the length of the region in the aerosol product 200 that contains the aerosol-generating substance and / or medium. A portion of the aerosol product 200 may be inserted into the housing 101, and another portion of the aerosol product 200 may protrude outward from the housing 101.

[0152] With the aerosol product 200 inserted into the first containment 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 product 200 can be mixed with air flowing into the first containment space 210 to generate an aerosol. The user can inhale the generated aerosol by bringing their mouth into contact with the other portion of the aerosol product 200 that protrudes outward from the housing 101.

[0153] The cartridge 300 may include an atomizing unit equipped with a storage tank 320 for storing aerosol-generating material and a cartridge heater 330 for heating the aerosol-generating material. With the cartridge 300 housed in the second containment space 310, the aerosol-generating material stored in the storage tank 320 can be heated by the cartridge heater 330 to generate vapor. The vapor generated from the cartridge 300 can be mixed with air flowing into the second containment space 310 to generate an aerosol.

[0154] The first airflow passage 400 is located inside the housing 101 and can connect the first containment space 210 and the second containment space 310. The aerosol generated from the cartridge 300 contained in the second containment space 310 flows into the first containment space 210 through the first airflow passage 400 and can be mixed with the aerosol generated from the aerosol product 200 inserted into the first containment space 210. The user can inhale the mixed aerosol by bringing their mouth into contact with the other portion of the aerosol product 200 that protrudes toward the outside of the housing 101.

[0155] The aerosol generated from cartridge 300 may be cooled as it moves from the second containment space 310 along the first airflow passage 400 to the first containment space 210. Since the aerosol generated from cartridge 300 is mixed with the aerosol generated from aerosol product 200 while cooled, the mixed aerosol may also be cooled. This allows the user to contact the other portion of aerosol product 200 that protrudes outward from the housing 101 with their mouth and inhale the aerosol cooled to a temperature suitable for inhalation.

[0156] The aerosol generator 100 may include a first heat dissipation member 420 located inside the housing 101 to absorb heat generated from inside the battery housing space 110. For example, the first heat dissipation member 420 may be located between the first airflow passage 400 and the battery housing space 110 to absorb heat generated from inside the battery housing space 110.

[0157] The battery 111 can be detachably coupled to the battery housing space 110. The battery 111 is coupled to the battery housing space 110 and can supply power for the operation of the components of the aerosol generator 100. When the battery 111 is charged or used, heat is generated from the battery 111, and the heat generated from the battery 111 affects the performance of the aerosol generator 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 a suitable temperature.

[0158] If the battery 111 is overcharged or over-discharged, or if the battery 111 deteriorates or its durability is weakened by external impact, abnormal overheating may occur from the battery 111. Overheating from the battery 111 affects the performance of other components of the aerosol generator 100 located around the battery 111. For example, overheating from the battery 111 may cause the article heater 230 and / or the cartridge heater 330 to malfunction and / or be damaged.

[0159] The first heat dissipation member 420 is positioned between the first airflow passage 400 and the battery housing space 110, and can prevent heat generated from the battery 111 from being transferred from the battery housing space 110 to the first airflow passage 400, the article heater 230 and / or the cartridge heater 330.

[0160] The first heat dissipation member 420 absorbs heat generated from inside the battery housing space 110 and prevents 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 product 200 from rising due to heat generated from the battery 111. By providing the first heat dissipation member 420 positioned between the first airflow passage 400 and the battery housing space 110, the aerosol generator 100 allows the user to inhale aerosol cooled to a suitable temperature.

[0161] The first heat dissipation member 420 absorbs heat generated from inside the battery housing space 110 and prevents heat generated from the battery 111 from being transferred to the article heater 230 and the cartridge heater 330. By providing the first heat dissipation member 420 positioned between the first airflow passage 400 and the battery housing space 110, the aerosol generator 100 can prevent malfunction and / or damage to the article heater 230 and the cartridge heater 330 due to heat generated from the battery 111.

[0162] As another example, the first heat dissipation member 420 is positioned around the battery housing space 110 inside the housing 101 and can absorb heat generated from inside the battery housing space 110. The first heat dissipation member 420 may be located inside the housing 101 and positioned to surround at least one area of ​​the outer circumferential surface of the battery housing space 110.

[0163] The first heat dissipation member 420 is positioned around the battery housing space 110 inside the housing 101, preventing heat generated from the battery 111 from being transferred from the battery housing space 110 to the article heater 230 and / or the cartridge heater 330. By providing the first heat dissipation member 420 positioned between the first airflow passage 400 and the battery housing space 110, the aerosol generator 100 can prevent malfunction and / or damage to the article heater 230 and the cartridge heater 330 due to heat generated from the battery 111.

[0164] The second airflow passage 410 is located inside the housing 101 and can connect the outside of the aerosol generator 100 to the battery housing space 110. After the outside air moves into the battery housing space 110 along the second airflow passage 410, it can then move back out of the aerosol generator 100 along the second airflow passage 410.

[0165] The housing 101 may further include one or more air vents that penetrate the housing 101. Outside air may flow into the aerosol generator 100 through one air vent, move into the battery housing space 110 along the second airflow passage 410, then move again along the second airflow passage 410 and be discharged to the outside of the aerosol generator 100 through another air vent.

[0166] The second airflow passage 410 may include one or more small holes in at least one region (for example, region A shown in Figure 4). For example, referring to Figure 5A, the second airflow passage 410 may include a plurality of perforations 510. The arrangement of a plurality of perforations 510 in the second airflow passage 410 can improve the airflow of the battery housing space 110. As another example, referring to Figure 5B, the second airflow passage 410 may include a mesh-like structure 520. For example, the mesh-like structure 520 is a metal sheet. However, it is not limited to this, and as another example, the mesh-like structure 520 is a sheet containing plastic or polyethylene terephthalate (PET). The inclusion of a mesh-like structure 520 in the second airflow passage 410 can improve the airflow of the battery housing space 110.

[0167] The second airflow passage 410 effectively dissipates heat generated from the battery 111, thereby minimizing external heat generation in the battery housing space 110. If the battery 111 overheats, the heat will cause components of the aerosol generator 100 located around the battery 111 to malfunction or fail. Furthermore, the overheating from the battery 111 can cause the battery housing space 110 to become excessively hot, potentially causing burns to the hands of users of the aerosol generator 100.

[0168] The aerosol generator 100 minimizes external heat generation from the battery housing space 110 through the second airflow passage 410, thereby preventing malfunction and / or damage to the internal components of the aerosol generator 100 due to heat generated from the battery 111, and preventing users of the aerosol generator 100 from burning their hands due to heat generated from the battery 111.

[0169] Figure 6 is a drawing illustrating a second heat dissipation member of an aerosol generator according to one embodiment. Referring to Figure 6, the aerosol generator 100 according to one embodiment may include a housing 101, a battery 111, a second heat dissipation member 440, and a battery cover 600. Figure 6 shows a simplified representation of the components of the aerosol generator 100 illustrating the second heat dissipation member 440 and the battery cover 600, and the components included in the aerosol generator 100 according to one embodiment are not limited to those shown in Figure 6. The components of the aerosol generator 100 according to one embodiment may be replaced with other components, or additional components may be added to the aerosol generator 100. For example, at least one of the components of the aerosol generator 100 in Figure 6 is identical or similar to the components of the aerosol generator 100 described with reference to Figures 1 to 5, and redundant explanations will be omitted below.

[0170] The housing 101 forms the exterior of the aerosol generator 100, and components of the aerosol generator 100 may be arranged in the internal space of the housing 101. The housing 101 may include a battery housing space 110 for housing a battery 111. The battery housing space 110 may be formed on one side of the housing 101 (for example, the side facing the +x axis). The battery housing space 110 may be recessed inward from the housing 101 to accommodate the battery 111. The depth to which the battery housing space 110 is recessed may correspond to the thickness of the battery 111 (for example, the length of the battery 111 in the x-axis direction).

[0171] The battery 111 is coupled to or housed in the battery housing space 110 and can supply power for the operation of components located in the internal space of the housing 101. The battery 111 is formed in the shape of a rectangular prism, but is not limited to a rectangular or rounded rectangle, with a cross-section (for example, a cross-section of the battery 111 by the xy plane) being rectangular or a rounded rectangle.

[0172] The battery cover 600 is detachably attached to the housing 101 and can protect the battery 111 housed in the battery compartment 110 from external impacts or foreign objects. The battery cover 600 can open the battery compartment 110 when detached from or separated from the housing 101, and can close the battery compartment when attached to or connected to the housing 101.

[0173] When the battery cover 600 is removed from the housing 101, the battery housing space 110 may be exposed to the outside. With the battery cover 600 removed from the housing 101, batteries 111 that have reached the end of their lifespan or require charging may be separated from the battery housing space 110, and newly charged batteries 111 may be coupled to the battery housing space 110.

[0174] The battery cover 600 may include an outer battery cover 610, an inner battery cover 620, and projections 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 multiple perforations. The arrangement of multiple perforations in the battery cover 600 may improve the ventilation of the battery housing space 110. As another example, the battery cover 600 may include a mesh-like structure. The mesh-like structure is a sheet of metal. However, it is not limited to a sheet of plastic or polyethylene terephthalate. The inclusion of a mesh-like structure in the battery cover 600 may improve the ventilation of the battery housing space 110.

[0175] The outer battery cover 610 is positioned in one area of ​​the housing 101 and can form the outer surface of the battery cover 600 (for example, the surface facing the +x axis). After the battery 111 is housed in the battery housing space 110, the outer battery cover 610 can protect the battery 111 from external impacts or foreign objects by closing the battery housing space 110.

[0176] The inner battery cover 620 is formed from the center of the inner surface of the battery cover 600 (e.g., the -x axis plane) and may project in a direction toward the interior of the battery housing space 110 (e.g., in the -x axis direction). After the battery 111 is housed in the battery housing space 110, and the battery cover 600 and housing 101 are joined, the inner battery cover 620 can pressurize the battery 111 toward the housing 101 (e.g., in the -x axis direction). By pressurizing the battery 111 with the inner battery cover 620, the battery 111 is secured in the battery housing space 110, and thus the battery 111 can be protected from external impacts.

[0177] The projection 630 is formed along the edge of the inner surface of the battery cover 600 and may protrude into the battery housing space 110. For example, the projection 630 has the shape of a rectangular ring protruding when the inner surface of the battery cover 500 is viewed in the direction of the +x axis. The projection 630 may be inserted into and fitted into a groove 120 formed in the housing 101. By fitting the projection 630 of the battery cover 600 into the groove 120 of the housing 101, the battery cover 600 may be coupled to or fixed to the housing 101.

[0178] The second heat dissipation member 440 is located between the projection 630 and the groove 120 when the battery cover 600 is coupled to the housing 101, and can absorb heat generated from inside the battery housing space 110.

[0179] The second heat dissipation member 440 prevents heat generated from the battery 111 from being transferred from the battery housing space 110 to the article heater 230 and / or the cartridge heater 330, thereby preventing malfunction and / or damage to the article heater 230 and the cartridge heater 330 due to heat generated from the battery 111.

[0180] The second heat dissipation member 440 effectively releases heat generated from the battery 111, thereby minimizing external heat generation in the battery housing space 110. The second heat dissipation member 440 can prevent users of the aerosol generator 100 from suffering burns to their hands due to heat generated from the battery 111.

[0181] Although not shown in the figure, the aerosol generator 100 in Figure 6 further includes a second airflow passage as described with reference to Figure 4, and the second airflow passage will be described later with reference to Figure 8.

[0182] Figure 7 is a drawing illustrating the second heat dissipation member of an aerosol generator according to another embodiment. Referring to Figure 7, the aerosol generator 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 generator 100 in Figure 7 is an aerosol generator that differs from the aerosol generator 100 in Figure 6 only in the shape and arrangement of the housing 101, battery 111, second heat dissipation member 440, and battery cover 600, and redundant explanations will be omitted below.

[0183] The housing 101 may include a battery housing space 110 for housing a battery 111. The battery housing space 110 may be formed on one side of the housing 101 (for example, the side facing the -z axis). The battery housing space 110 may be recessed inward from the housing 101 to accommodate the battery 111. The depth to which the battery housing space 110 is recessed may correspond to the length of the battery 111 (for example, the length of the battery 111 in the z-axis direction).

[0184] The battery 111 is coupled to or housed in the battery housing space 110 and can supply power for the operation of components located in the internal space of the housing 101. The battery 111 is formed in a cylindrical shape with a circular or elliptical cross-section (for example, the cross-section of the battery 111 by the xy plane), but is not limited to this.

[0185] The battery cover 600 is detachably attached to the housing 101 and can protect the battery 111 housed in the battery compartment 110 from external impacts or foreign objects. The battery cover 600 may include an outer battery cover 610, an inner battery cover 620, and a projection 630.

[0186] The outer battery cover 610 is positioned in one area of ​​the housing 101 and can form the outer surface of the battery cover 600 (e.g., the surface facing the -z axis). The inner battery cover 620 is formed from the center of the inner surface of the battery cover 600 (e.g., the surface facing the +z axis) and can project in a direction toward the interior of the battery housing space 110 (e.g., in the +z axis direction). After the battery 111 is housed in the battery housing space 110, and the battery cover 600 and the housing 101 are joined, the inner battery cover 620 can press the battery 111 toward the housing 101 (e.g., in the +z axis direction).

[0187] The projection 630 is formed along the edge of the inner surface of the battery cover 600 and may protrude into the battery housing space 110. For example, the projection 630 has the shape of a circular ring protruding when the inner surface of the battery cover 500 is viewed in the direction of the -z axis. The projection 630 may be inserted into and fitted into a groove 120 formed in the housing 101. By fitting the projection 630 of the battery cover 600 into the groove 120 of the housing 101, the battery cover 600 may be coupled to or fixed to the housing 101.

[0188] The second heat dissipation member 440 is located between the projection 630 and the groove 120 when the battery cover 600 is coupled to the housing 101, and can absorb heat generated from inside the battery housing space 110.

[0189] The second heat dissipation member 440 prevents heat generated from the battery 111 from being transferred from the battery housing space 110 to the article heater 230 and / or the cartridge heater 330, thereby preventing malfunction and / or damage to the article heater 230 and the cartridge heater 330 due to heat generated from the battery 111.

[0190] The second heat dissipation member 440 effectively releases heat generated from the battery 111, thereby minimizing external heat generation in the battery housing space 110. The second heat dissipation member 440 can prevent users of the aerosol generator 100 from suffering burns to their hands due to heat generated from the battery 111.

[0191] Although not shown in the figures, the aerosol generator 100 in Figure 7 further includes a second airflow passage as described with reference to Figure 4, and the second airflow passage will be described later with reference to Figures 9A and 9B.

[0192] Figure 8 is a diagram illustrating the arrangement structure of the second airflow passage in Figure 6. Figure 8 is a cross-sectional view in the yz plane of the aerosol generator 100 of Figure 6 with the second airflow passage 410 and air holes 800 added, and repeated explanations will be omitted below. The arrows in Figure 8 indicate the movement path of air (or "outside air").

[0193] Referring to Figure 8, the second airflow passage 410 may be located inside the housing 101 and arranged so that outside air flowing into the battery housing space 110 moves along the edge of the battery housing space 110 and then moves again to the outside of the aerosol generator 100. The second airflow passage 410 may be formed in a shape that is bent multiple times in a direction parallel to, perpendicular to, or oblique to the longitudinal direction (e.g., the z-axis direction) of the housing 101. The more complex the shape of the second airflow passage 410, the more efficiently the heat generated from the battery 111 is released to the outside of the aerosol generator 100, thereby minimizing external heat generation in the battery housing space 110.

[0194] The housing 101 may include one or more air vents 800 that penetrate the housing 101. For example, the first air vent 801 and the third air vent 803 may be formed on one side of the housing 101 (e.g., the side facing the -y axis), and the second air vent 802 and the fourth air vent 804 may be formed on the other side of the housing 101 (e.g., the side facing the +y axis). However, the number and arrangement of the air vents 800 are not limited thereto. As another example, the third air vent 803 and the fourth air vent 804 may be formed on yet another side of the housing 101 (e.g., the side facing the -z axis).

[0195] The aerosol generator 100 effectively dissipates heat generated from the battery 111 by utilizing the second airflow passage 410 and air vents 800, thereby minimizing external heat generation in the battery housing space 110. By minimizing external heat generation in the battery housing space 110, the aerosol generator 100 equipped with the second airflow passage 410 and air vents 800 prevents malfunction and / or damage to the internal components of the aerosol generator 100 due to heat generated from the battery 111, and prevents users of the aerosol generator 100 from burning their hands due to heat generated from the battery 111.

[0196] Figure 9A is a diagram illustrating the arrangement structure of the second airflow passage in Figure 7 as one example, and Figure 9B is a diagram illustrating the arrangement structure of the second airflow passage in Figure 7 as another example. Figures 9A and 9B are cross-sectional views in the yz plane of an aerosol generator 100 of Figure 7 to which a second airflow passage 410 and air holes 800 have been added, and repeated explanations will be omitted below. The arrows in Figures 9A and 9B indicate the movement path of air (or "outside air").

[0197] Referring to Figure 9A, the second airflow passage 410 may be located inside the housing 101 and positioned so that outside air flowing into the battery housing space 110 moves along the edge of the battery housing space 110 and then moves again to the outside of the aerosol generator 100. The second airflow passage 410 may be formed in a shape that is bent multiple times in a direction parallel to, perpendicular to, or oblique to the longitudinal direction (e.g., the z-axis direction) of the housing 101. The more complex the shape of the second airflow passage 410, the more efficiently the heat generated from the battery 111 is released to the outside of the aerosol generator 100, thereby minimizing external heat generation in the battery housing space 110.

[0198] The housing 101 may include one or more air vents 800 that penetrate the housing 101. For example, a first air vent 801 and a third air vent 803 may be formed on one side of the housing 101 (e.g., the side facing the -y axis), a second air vent 802 and a fourth air vent 804 may be formed on the other side of the housing 101 (e.g., the side facing the +y axis), and a fifth air vent 805 and a sixth air vent 806 may be formed on yet another side of the housing 101 (e.g., the side facing the -z axis). However, the number and arrangement of the air vents 800 are not limited thereto. As another example, three air vents may be formed on one side of the housing 101 (e.g., the side facing the -y axis), and four air vents may be formed on the other side of the housing 101 (e.g., the side facing the +y axis).

[0199] Referring to Figure 9B, the second airflow passage 410 may be located inside the housing 101 and arranged so that outside air flowing into the battery housing space 110 moves along the outer surface of the battery housing space 110 and then moves again to the outside of the aerosol generator 100. The second airflow passage 410 may be formed in a shape that is bent multiple times in a direction parallel to, perpendicular to, or oblique to the longitudinal direction (e.g., the z-axis direction) of the housing 101. The more complex the shape of the second airflow passage 410, the more efficiently the heat generated from the battery 111 is released to the outside of the aerosol generator 100, thereby minimizing external heat generation in the battery housing space 110.

[0200] The housing 101 may include one or more air vents 800 that penetrate the housing 101. For example, a seventh air vent 807 may be formed on one side of the housing 101 (e.g., the side facing the -y axis), an eighth air vent 808 may be formed on the other side of the housing 101 (e.g., the side facing the +y axis), and a ninth air vent 809 and a tenth air vent 810 may be formed on yet another side of the housing 101 (e.g., the side facing the -z axis). However, the number and arrangement of the air vents 800 are not limited thereto.

[0201] The aerosol generator 100 effectively dissipates heat generated from the battery 111 by utilizing the second airflow passage 410 and air vents 800, thereby minimizing external heat generation in the battery housing space 110. By minimizing external heat generation in the battery housing space 110, the aerosol generator 100 equipped with the second airflow passage 410 and air vents 800 prevents malfunction and / or damage to the internal components of the aerosol generator 100 due to heat generated from the battery 111, and prevents users of the aerosol generator 100 from burning their hands due to heat generated from the battery 111.

[0202] Figure 10 is a block diagram of an aerosol generating apparatus according to another embodiment.

[0203] The aerosol generator 1 includes a power supply 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 Figure 10. That is, a person with ordinary skill in the art according to this embodiment will understand that some of the components shown in Figure 10 may be omitted or new components may be added depending on the design of the aerosol generator 1.

[0204] Sensor 13 can sense the state of the aerosol generator 1 or the state of the area around the aerosol generator 1, and transmit the sensed information to the control unit 12. Based on the sensed information, the control unit 12 can control the aerosol generator 1 to perform various functions such as controlling the operation of the cartridge heater 24 and / or heater 18, restricting smoking, determining whether or not the stick S and / or cartridge 19 is inserted, and displaying notifications.

[0205] Sensor 13 includes at least one of the following: temperature sensor 1031, puff sensor 1032, insertion sensor 1033, reuse sensor 1034, cartridge sensor 1035, cap sensor 1036, and motion sensor 1037.

[0206] The temperature sensor 1031 can sense the temperature at which the cartridge heater 24 and / or heater 18 are heated. The aerosol generator 1 may include a separate temperature sensor that senses the temperature of the cartridge heater 24 and / or heater 18, or the cartridge heater 24 and / or heater 18 themselves may act as the temperature sensor.

[0207] The temperature sensor 1031 can output a signal corresponding to the temperature of the cartridge heater 24 and / or heater 18. For example, the temperature sensor 1031 includes a resistive element whose resistance changes in response to temperature changes in the cartridge heater 24 and / or heater 18. This is embodied by an element such as a thermistor, which utilizes the property that resistance changes with temperature. In this case, the temperature sensor 1031 can output a signal corresponding to the resistance value of the resistive element as a signal corresponding to the temperature of the cartridge heater 24 and / or heater 18. For example, the temperature sensor 1031 is composed of a sensor that detects the resistance value of the cartridge heater 24 and / or heater 18.

For example, before the stick S is used by a user, at least a portion of the flaps has a first hue. In this case, as the aerosol generated by the aerosol generator 1 passes through the stick S, at least a portion of the flaps may be wetted by the aerosol, causing at least a portion of the flaps to change to a second hue.

Also, although not shown in Figure 10, a noise filter may be provided between the power supply 11 and the heater 18. The noise filter is also 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 corresponds to the frequency of the high-frequency switching current applied from the power supply 11 to the heater 18.

[0240] The control unit 12 can control the overall operation of the aerosol generator 1. In one embodiment, the control unit 12 includes at least one processor. The processor may be embodied as an array of numerous logic gates, or as a combination of a general-purpose microprocessor and memory storing a program executable by the microprocessor. It will be understood by those ordinary skill in the art to which this embodiment belongs that it may also be embodied by other forms of hardware.

[0241] The control unit 12 can control the temperature of the heater 18 by controlling the supply of power from the power supply 11 to the heater 18. The control unit 12 can control the temperature of the cartridge heater 24 and / or heater 18 based on the temperature of the cartridge heater 24 and / or heater 18 sensed by the temperature sensor 1031. The control unit 12 can adjust the power supplied to the cartridge heater 24 and / or heater 18 based on the temperature of the cartridge heater 24 and / or heater 18. For example, the control unit 12 can determine a target temperature for the cartridge heater 24 and / or heater 18 based on a temperature profile stored in the memory 17.

[0242] 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 heater 18. The power supply circuit may be electrically connected to the cartridge heater 24, heater 18, or induction coil 181. The power supply circuit includes at least one switching element. The switching element is embodied by a bipolar junction transistor (BJT), a field-effect transistor (FET), etc. The control unit 12 can control the power supply circuit.

[0243] The control unit 12 can control the power supply by controlling the switching of the switching elements in the power supply circuit. The power supply circuit is also an inverter that converts the DC power output from the power supply 11 into AC power. For example, the inverter is composed of a full-bridge circuit or a half-bridge circuit that includes multiple switching elements.

[0244] The control unit 12 can turn on the switching element so that power is supplied from the power supply 11 to the cartridge heater 24 and / or heater 18. The control unit 12 can turn off the switching element so that the power supply to the cartridge heater 24 and / or heater 18 is cut off. The control unit 12 can adjust the current supplied from the power supply 11 by adjusting the frequency and / or duty cycle of the current pulse input to the switching element.

[0245] The control unit 12 can control the voltage output from the power supply 11 by controlling the switching of the switching elements in the power supply circuit. The power conversion circuit can convert the voltage output from the power supply 11. For example, the power conversion circuit includes a buck converter that steps down the voltage output from the power supply 11. For example, the power conversion circuit is implemented through a buck boost converter, a Zener diode, etc.

[0246] The control unit 12 can control the on / off operation of the switching element included in the power conversion circuit and adjust the level of the voltage output from the power conversion circuit. When the switching element remains in the on state, the level of the voltage output from the power conversion circuit corresponds to the level of the voltage output from the power supply 11. The duty cycle for the on / off operation of the switching element corresponds to the ratio of the voltage output from the power conversion circuit to the voltage output from the power supply 11. The lower the duty cycle for the on / off operation of the switching element, the lower the level of the voltage output from the power conversion circuit may be. The heater 18 may be heated based on the voltage output from the power conversion circuit.

[0247] The control unit 12 can control the supply of power to the heater 18 using at least one of the following methods: pulse width modulation (PWM) and proportional-integral-differential (PID).

[0248] For example, the control unit 12 can use a PWM method to control the supply of current pulses having a predetermined frequency and duty cycle to the heater 18. The control unit 12 can adjust the frequency and duty cycle of the current pulses to control the power supplied to the heater 18.

[0249] For example, the control unit 12 can determine a target temperature for control based on the temperature profile. The control unit 12 can control the power supplied to the heater 18 using a PID method, which is a feedback control method that uses the difference between the heater temperature and the target temperature, the integral of the difference over time, and the derivative of the difference over time.

[0250] The control unit 12 can prevent the cartridge heater 24 and / or heater 18 from overheating. For example, the control unit 12 can control the operation of the power conversion circuit so that the power supply to the cartridge heater 24 and / or heater 18 is interrupted based on the temperature of the cartridge heater 24 and / or heater 18 exceeding a predetermined limit temperature. For example, the control unit 12 can reduce the amount of power supplied to the cartridge heater 24 and / or heater 18 by a certain percentage based on the temperature of the cartridge heater 24 and / or heater 18 exceeding a predetermined limit temperature. For example, the control unit 12 can determine that the aerosol-generating material contained in the cartridge 19 has been exhausted based on the temperature of the cartridge heater 24 exceeding a limit temperature and cut off the power supply to the cartridge heater 24.

[0251] The control unit 12 can control the charging and discharging of the power supply 11. The control unit 12 can check the temperature of the power supply 11 based on the output signal of the temperature sensor 1031.

[0252] When a power line is connected to the battery terminal of the aerosol generator 1, the control unit 12 can check whether the temperature of the power supply 11 is equal to or above a first limiting temperature, which is the criterion for shutting off the charging of the power supply 11. If the temperature of the power supply 11 is below the first limiting temperature, the control unit 12 can control the charging of the power supply 11 based on a predetermined charging current. If the temperature of the power supply 11 is equal to or above the first limiting temperature, the control unit 12 can shut off the charging of the power supply 11.

[0253] With the power supply of the aerosol generator 1 turned on, the control unit 12 can check whether the temperature of the power supply 11 is above the second limiting temperature, which is the criterion for shutting off the discharge of the power supply 11. If the temperature of the power supply 11 is below the second limiting temperature, the control unit 12 can control the power supply 11 to use the stored power. If the temperature of the power supply 11 is above the second limiting temperature, the control unit 12 can interrupt the use of the stored power.

[0254] The control unit 12 can calculate the remaining capacity of the power supply 11 relative to the power stored in the power supply 11. For example, the control unit 12 can calculate the remaining capacity of the power supply 11 based on the voltage and / or current sensing values ​​of the power supply 11.

[0255] The control unit 12 can determine whether or not the stick S is inserted into the insertion space via the insertion sensing sensor 1033. Based on the output signal of the insertion sensing sensor 1033, the control unit 12 can determine that the stick S has been inserted. If it determines that the stick S has been inserted into the insertion space, the control unit 12 can control the supply of power to the cartridge heater 24 and / or heater 18. For example, the control unit 12 can supply power to the cartridge heater 24 and / or heater 18 based on the temperature profile stored in the memory 17.

[0256] The control unit 12 can determine whether or not the stick S has been removed from the insertion space. For example, the control unit 12 can determine whether or not the stick S has been removed from the insertion space through the insertion sensing sensor 1033. For example, the control unit 12 can determine that the stick S has been removed from the insertion space if the temperature of the heater 18 is above a limit temperature, or if the temperature change gradient of the heater 18 is above a set gradient. If the control unit 12 determines that the stick S has been removed from the insertion space, it can cut off the power supply to the cartridge heater 24 and / or heater 18.

[0257] The control unit 12 can control the power supply time and / or power supply amount to the heater 18 based on the state of the stick S sensed by the sensor 13. The control unit 12 can determine the level range that includes the level of the capacitance sensor signal based on a lookup table. The control unit 12 can determine the amount of moisture in the stick S based on the determined level range.

[0258] When the stick S is in an over-humidified state, the control unit 12 controls the power supply time to the heater 18, and can increase the preheating time of the stick S compared to the normal state.

[0259] The control unit 12 can determine whether the stick S inserted into the insertion space is to be reused through the reuse sensing sensor 1034. For example, the control unit 12 can compare the sensing value of the reuse sensing sensor signal with a first reference range that includes a first hue, and if the sensing value falls within the first reference range, it can determine that the stick S is not being used. For example, the control unit 12 can compare the sensing value of the reuse sensing sensor signal with a second reference range that includes a second hue, and if the sensing value falls within the second reference range, it can determine that the stick S has been used. If it is determined that the stick S has been used, the control unit 12 can cut off the power supply to the cartridge heater 24 and / or heater 18.

[0260] The control unit 12 can determine whether to connect and / or remove the cartridge 19 through the cartridge sensing sensor 1035. For example, the control unit 12 can determine whether to connect and / or remove the cartridge 19 based on the sensing value of the signal from the cartridge sensing sensor.

[0261] The control unit 12 can determine whether or not the aerosol-generating material in the cartridge 19 has been exhausted. For example, the control unit 12 can preheat the cartridge heater 24 and / or heater 18 by applying power, and determine whether or not the temperature of the cartridge heater 24 exceeds a limit temperature during the preheating period. If the temperature of the cartridge heater 24 exceeds the limit temperature, the control unit 12 can determine that the aerosol-generating material in the cartridge 19 has been exhausted. If the control unit 12 determines that the aerosol-generating material in the cartridge 19 has been exhausted, it can cut off the power supply to the cartridge heater 24 and / or heater 18.

[0262] The control unit 12 can determine whether or not the cartridge 19 can be used. For example, based on the data stored in the memory 17, the control unit 12 can determine that the cartridge 19 cannot be used if the current number of puffs is greater than or equal to the maximum number of puffs set for the cartridge 19. For example, the control unit 12 can determine that the cartridge 19 cannot be used if the total time the heater 24 has been heated is greater than or equal to a predetermined maximum time, or if the total amount of power supplied to the heater 24 is greater than or equal to a predetermined maximum amount of power.

[0263] The control unit 12 can make decisions regarding the user's inhalation through the puff sensor 1032. For example, the control unit 12 can determine whether or not a puff has occurred based on the sensing value of the signal from the puff sensor. For example, the control unit 12 can determine the intensity of the puff based on the sensing value of the signal from the puff sensor 1032. If the number of puffs reaches a predetermined maximum number of puffs, or if no puff is detected for a predetermined time or longer, the control unit 12 can cut off the power supply to the cartridge heater 24 and / or heater 18.

[0264] The control unit 12 can determine whether the cap is attached and / or removed via the cap sensing sensor 1036. For example, the control unit 12 can determine whether the cap is attached and / or removed based on the sensing value of the signal from the cap sensing sensor.

[0265] The control unit 12 can control the output unit 14 based on the results sensed by the sensor 13. For example, if the number of puffs counted through the puff sensor 1032 reaches a predetermined number, the control unit 12 can notify the user that the aerosol generator 1 will soon shut off through at least one of the display 1041, the haptic unit 1042, and the acoustic output unit 1043. For example, the control unit 12 can notify the user through the output unit 14 based on the determination that there is no stick S in the insertion space. For example, the control unit 12 can notify the user through the output unit 14 based on the determination that the cartridge 19 and / or cap is not installed. For example, the control unit 12 can transmit information about the temperature of the cartridge heater 24 and / or heater 18 to the user through the output unit 14.

[0266] The control unit 12 can save and update a history of events in the memory 17 based on the occurrence of a predetermined event. Events include operations performed by the aerosol generator 1, such as detection of stick S insertion, start of stick S heating, puff detection, end of puffing, detection of overheating of the cartridge heater 24 and / or heater 18, detection of overvoltage application to the cartridge heater 24 and / or heater 18, end of stick S heating, on / off of the aerosol generator 1, start of charging of the power supply 11, detection of overcharge of the power supply 11, and end of charging of the power supply 11. The history of events includes the date and time the event occurred, log data corresponding to the event, etc. For example, if a predetermined event is the detection of stick S insertion, the log data corresponding to the event includes data such as the sensing value of the insertion detection sensor 1033. For example, if a predetermined event is the detection of overheating of the cartridge heater 24 and / or heater 18, the log data corresponding to the event will include data on the temperature of the cartridge heater 24 and / or heater 18, the voltage applied to the cartridge heater 24 and / or heater 18, and the current flowing through the cartridge heater 24 and / or heater 18.

[0267] The control unit 12 can be controlled to form a communication link with an external device, such as a user's mobile terminal. Upon receiving authentication data from the external device via the communication link, the control unit 12 can remove the restriction on the use of at least one function of the aerosol generator 1. Here, the authentication data includes data indicating the completion of user authentication for the user corresponding to the external device. The user can perform user authentication through the external device. The external device can determine whether the user data is valid based on the user's date of birth, a unique number identifying the user, etc., and can receive data regarding the right to use the aerosol generator 1 from an external server. Based on the data regarding the right to use, the external device can transmit data indicating the completion of user authentication to the aerosol generator 1. Once user authentication is complete, the control unit 12 can remove the restriction on the use of at least one function of the aerosol generator 1. For example, once user authentication is complete, the control unit 12 can remove the restriction on the use of the heating function that supplies power to the heater 18.

[0268] The control unit 12 can transmit data related to the status of the aerosol generator 1 to the external device via a communication link formed with the external device. Based on the received status data, the external device can output the remaining capacity of the power supply 11 of the aerosol generator 1, the operating mode, etc., through the external device's display.

[0269] An external device can transmit a location search request to the aerosol generator 1 based on an input that initiates a location search for the aerosol generator 1. When the control unit 12 receives a location search request from the external device, it can control at least one of the output devices to perform an operation corresponding to the location search based on the received location search request. For example, the haptic unit 1042 may generate vibrations in response to the location search request. For example, the display 1041 may output an object corresponding to the location search and the end of the search in response to the location search request.

[0270] The control unit 12 can control the aerosol generator 1 to perform a firmware update when it receives firmware data from an external device. The external device can check the current firmware version of the aerosol generator 1 and determine whether a new firmware version exists. When the external device receives an input requesting a firmware download, it can receive the new firmware version data and transmit the new firmware version data to the aerosol generator 1. Upon receiving the new firmware version data, the control unit 12 can control the aerosol generator 1 to perform a firmware update.
