Description

Technical Field

[0001] One or more embodiments of this disclosure relate to an aerosol generating apparatus, and more specifically to an aerosol generating apparatus having a structure in which aerosols generated inside the aerosol generating apparatus can be rapidly discharged to the outside. Background Technology

[0002] There is a growing demand for aerosol generating devices that produce aerosols in a non-combustible manner as an alternative to traditional combustible cigarettes. These devices can generate aerosols for users from aerosol-generating materials in a non-combustible manner. Furthermore, some aerosol generating devices can produce flavored aerosols by passing vapors generated from aerosol-generating materials through an aromatic medium.

[0003] The aerosol generating material used in an aerosol generating device can be in a solid state, such as cigarette smoke, a flowing liquid state, or a gel state. The aerosol generating material can be stored in an aerosol generating material reservoir within the aerosol generating device or in a cartridge used in conjunction with the aerosol generating device. When the aerosol generating material is depleted, it can be refilled into the aerosol generating material reservoir, or a new cartridge can be replaced, allowing the aerosol generating device to continue operating. Summary of the Invention

[0004] Technical issues

[0005] Before being discharged outside the aerosol generating device, the aerosol may liquefy and / or condense. Because liquefied and / or condensed aerosols are adhesive, they may adhere to or accumulate within the aerosol generating device, potentially reducing its durability and user satisfaction with smoking.

[0006] The problems solved by the implementation methods are not limited to those described above, and those skilled in the art to which this disclosure pertains can clearly understand the undescribed problems based on the application documents and drawings.

[0007] Solution to the problem

[0008] An aerosol generating apparatus according to an embodiment may include: an aerosol generating substance reservoir configured to store aerosol generating substances; an atomizer configured to atomize the aerosol generating substances into aerosols; an inflow channel configured to provide fluid communication between the exterior of the aerosol generating apparatus and the atomizer; an outlet channel surrounded by a channel wall, wherein aerosols and air introduced from the exterior via the inflow channel are discharged from the aerosol generating apparatus via the outlet channel; and at least one convex surface configured to guide aerosols to the exterior of the aerosol generating apparatus by the Coanda effect, wherein the at least one convex surface includes a first convex surface projecting from the channel wall toward the outlet channel.

[0009] Beneficial effects of the invention

[0010] According to the aerosol generating apparatus of the embodiment, the aerosol discharge rate can be enhanced, thereby increasing the atomization amount of the aerosol generating apparatus and minimizing the liquefaction of aerosols in the airflow channel.

[0011] Furthermore, even when the aerosol generator is not in use, the aerosol generated by the residual heat of the atomizer is directed to the outside of the aerosol generator, thus keeping the inside of the aerosol generator clean.

[0012] The effects of the implementation are not limited to those described above, and those skilled in the art to which this disclosure pertains will clearly understand the effects not described based on this application and the accompanying drawings. Attached Figure Description

However, the meanings of these terms may change depending on intent, judicial precedent, the emergence of new technologies, etc. Furthermore, in certain cases, there may be terms arbitrarily chosen by the applicant. In such cases, the meaning of the term will be described in detail in the description of this disclosure. Therefore, the terminology used herein is not simply based on the name of the term but on its meaning and the content of this disclosure.

[0043] As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood as: including only a, including only b, including only c, including both a and b, including both a and c, including both b and c, or including all of a, b, and c.

[0044] When a component or layer is referred to as being "above," "on top of," "connected to," or "combined with" another component or layer, that component or layer may be arranged to be located above, on top of, connected to, or combined with another component or layer, with or without intermediate components or layers. In contrast, if a component or layer is referred to as being "directly above," "directly on top of," "directly connected to," or "directly combined with," then there are no additional components or layers between them. In this disclosure, the same reference numerals may refer to the same components.

[0045] Furthermore, unless explicitly stated otherwise, the term "comprising" and variations such as "including" or "including" will be understood to mean including the stated elements but not excluding any other elements. Additionally, the terms "device," "component," and "module" described in the application refer to a unit for processing at least one function and / or operation, and can be implemented by hardware components or software components and combinations thereof.

[0046] In the following description, the present disclosure will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are illustrated, enabling those skilled in the art to readily implement the present disclosure. However, the present disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein.

[0047] Furthermore, terms including ordinal numbers such as "first" or "second" as used in this application may be used to describe various components, but the component should not be limited by such terms. Terms are used only for the purpose of distinguishing one component from another.

[0048] Additionally, some components in the accompanying drawings may be shown exaggerated in size or proportion. Furthermore, components shown in some drawings may not be shown in others.

[0049] Furthermore, throughout the application, the "longitudinal direction" of a component can be the direction in which the component extends along an axis, and in this case, the axis of the component can refer to a direction in which the component extends further than on other axes intersecting said axis. For example, the longitudinal direction can refer to... Figure 6B The direction in which the airflow flows or flows out is parallel to the direction shown.

[0050] The term "downstream" can refer to the direction in which aerosols move towards the user's mouth within an aerosol-generating article (e.g., a cigarette or cartridge) during smoking, and the term "upstream" refers to the opposite direction of downstream. The terms "upstream" and "downstream" can be used to indicate the relative positions of parts of an aerosol-generating article. In this respect, the portion of the cigarette placed in the user's mouth corresponds to the downstream end of the cigarette. For example, Figure 6B The upstream of the discharge channel can be a position adjacent to the atomization space, while the downstream of the discharge channel can be a position adjacent to the discharge port.

[0051] Additionally, the term "inhalation," used throughout the application, can refer to the act of a user inhaling aerosols into their mouth, nose, and lungs.

[0054] Furthermore, the terminology used in this disclosure is for describing embodiments and is not intended to limit those embodiments. In this disclosure, unless otherwise stated, the singular form includes the plural form.

[0055] The present disclosure will be described in more detail below with reference to the accompanying drawings.

[0056] Figure 1 and Figure 2 This is a diagram showing an example of a cigarette being inserted into an aerosol generating device.

[0057] Reference Figure 1 and Figure 2 The aerosol generating device 100 may include a battery 110, a processor 120, a heater 130, and a vaporizer 140. Furthermore, a cigarette 200 may be inserted into the internal space of the aerosol generating device 100.

[0058] Figure 1 and Figure 2 The aerosol generating apparatus 100 shown includes a vaporizer 140. However, the implementation is not limited to this method, and the vaporizer 140 may be omitted. In the case where the vaporizer 140 is omitted from the aerosol generating apparatus 100, the cigarette 200 contains aerosol-generating substances such that when the cigarette 200 is heated by the heater 130, the cigarette 200 generates an aerosol.

[0059] Conversely, the heater 130 and / or cigarette 200 can be omitted from the aerosol generating device 100. In this case, the aerosol generating material included in the vaporizer 140 can be atomized by a heating element or a vibrator, and an aerosol can be generated from the vaporizer 140.

[0060] Figure 1 and Figure 2 Components of the aerosol generating apparatus 100 relevant to this embodiment are shown. Therefore, those skilled in the art related to this embodiment will understand that, in addition to… Figure 1 and Figure 2 In addition to the components shown, the aerosol generating apparatus 100 may also include other general-purpose components.

[0061] also, Figure 1 and Figure 2 The aerosol generating apparatus 100 shown includes a heater 130. However, the heater 130 can be omitted if necessary.

[0062] Figure 1 The battery 110, processor 120, carburetor 140, and heater 130 are shown to be arranged in series. Furthermore, Figure 2 The vaporizer 140 and heater 130 are shown to be arranged in parallel. However, the internal structure of the aerosol generating device 100 is not limited to... Figure 1 or Figure 2 The structure shown is as described. In other words, depending on the design of the aerosol generating device 100, the battery 110, processor 120, vaporizer 140, and heater 130 can be arranged in different ways.

[0063] When the cigarette 200 is inserted into the aerosol generating device 100, the aerosol generating device 100 can operate the vaporizer 140 to generate an aerosol. The aerosol generated by the vaporizer 140 is delivered to the user by passing through the cigarette 200. The vaporizer 140 will be described in more detail later.

[0064] Battery 110 can supply power for the operation of aerosol generating apparatus 100. For example, battery 100 can supply power to heat heater 130 or vaporizer 140, and can supply power for operating processor 120. In addition, battery 100 can supply power for the operation of displays, sensors, motors, etc. installed in aerosol generating apparatus 100.

[0065] The processor 120 typically controls the operation of the aerosol generating apparatus 100. Specifically, the processor 120 controls not only the operation of the battery 110, heater 130, and vaporizer 140, but also the operation of other components included in the aerosol generating apparatus 100. Furthermore, the processor 120 can check the status of each component of the aerosol generating apparatus 100 to determine whether the aerosol generating apparatus 100 is operational.

[0066] Processor 120 may include one or more components. For example, processor 120 may be implemented as an array of logic gates or as a combination of a general-purpose microprocessor and a memory storing a program that can be executed in the microprocessor. Those skilled in the art will understand that the processor may be implemented in other forms of hardware.

[0067] The heater 130 can be heated by electricity supplied from the battery 100. For example, when the cigarette 200 is inserted into the aerosol generating device 100, the heater 130 can be located outside the cigarette. Therefore, the heated heater 130 can raise the temperature of the aerosol generating substances in the cigarette.

[0068] Heater 130 may include a resistance heater. For example, heater 130 may include a conductive trace, and heater 130 may be heated when current flows through the conductive trace. However, heater 130 is not limited to the above example and may include any other heater that can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating apparatus 100 or may be set by the user.

[0069] As another example, heater 130 may include an induction heater. Specifically, heater 130 may include a conductive coil for heating the aerosol-generating article by an induction heating method, and the aerosol-generating article may include a base that can be heated by the induction heater.

[0070] Figure 1 and Figure 2 The heater 130 is shown positioned outside the cigarette 200, but the position of the cigarette 200 is not limited thereto. For example, the heater 130 may include a tubular heating element, a plate heating element, a needle heating element, or a rod heating element, and may heat the inside or outside of the cigarette 200 depending on the shape of the heating element.

[0071] Furthermore, the aerosol generating device 100 may include a plurality of heaters 130. Here, the plurality of heaters 130 may be inserted into the cigarette 200 or may be arranged outside the cigarette 200. Additionally, some of the plurality of heaters 130 may be inserted into the cigarette 200, and others may be arranged outside the cigarette 200. Furthermore, the shape of the heaters 130 is not limited to... Figure 1 and Figure 2 The shapes shown are, and can include a variety of shapes.

[0072] The vaporizer 140 can generate an aerosol by heating the liquid composition, and the generated aerosol can be delivered to the user through the cigarette 200. In other words, the aerosol generated by the vaporizer 140 can move along the airflow channel of the aerosol generating device 100, and the airflow channel can be configured such that the aerosol generated by the vaporizer 140 can be delivered to the user through the cigarette 200.

[0073] For example, vaporizer 140 may include a liquid storage unit, a liquid delivery element, and an atomizer (e.g., a heating element and / or a vibrator), but is not limited thereto. For example, the liquid storage unit, the liquid delivery element, and the atomizer may be included as separate modules in aerosol generating apparatus 100.

[0074] The liquid storage section can store a liquid composition that is an aerosol-generating substance. For example, the liquid composition can be a liquid containing tobacco substances having volatile tobacco aroma components, or a liquid containing non-tobacco substances. The liquid storage section can be detachable from the vaporizer 140, or it can be integrally formed with the vaporizer 140.

[0075] For example, the liquid composition may include water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruity flavorings. Flavorings may include ingredients capable of providing a variety of fragrances or flavors to the user. Vitamin mixtures may be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Furthermore, the liquid composition may include aerosol-forming substances such as glycerol and propylene glycol.

[0076] A liquid delivery element can deliver the liquid composition from the liquid reservoir to the atomizer. For example, the liquid delivery element can be a core such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited to these.

[0077] As an example of an atomizer, a heating element is a component used to heat a liquid composition conveyed by a liquid delivery element. For example, the heating element can be a metal heating wire, a metal heating plate, a ceramic heater, etc., but is not limited to these. Alternatively, the heating element can include a conductive wire such as a nickel-chromium alloy wire, and can be positioned to wrap around the liquid delivery element. The heating element can be heated by an electric current supply, and heat can be transferred to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.

[0078] For example, the vaporizer 140 may be referred to as a cartridge or atomizer, but is not limited to this.

[0079] The aerosol generating device 100 may also include general-purpose components other than the battery 110, processor 120, and heater 130. For example, the aerosol generating device 100 may include a display capable of outputting visual information and / or a motor for outputting tactile information.

[0080] Cigarette 200 can be similar to a regular combustible cigarette. For example, cigarette 200 can be divided into a first part including aerosol-generating substances and a second part including a filter, etc. Alternatively, the second part of cigarette 200 can also include aerosol-generating substances. For example, aerosol-generating substances made in the form of granules or capsules can be inserted into the second part.

[0081] The first part can be fully inserted into the aerosol generating device 100, and the second part can be exposed to the outside. Alternatively, only a portion of the first part can be inserted into the aerosol generating device 100, or a portion of the first part and a portion of the second part can be inserted into the aerosol generating device 100. The user can inhale the aerosol while holding the second part with their mouth. In this case, the aerosol is generated by external air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

[0082] For example, outside air can flow into at least one air passage formed in the aerosol generating device 100. For example, the opening and closing and / or size of the air passage formed in the aerosol generating device 100 can be adjusted by the user. Therefore, the amount of smoke and the smoking experience can be adjusted by the user. As another example, outside air can flow into the cigarette 200 through at least one hole formed in the surface of the cigarette 200.

[0083] In the following text, reference will be made to Figure 3 An example of cigarette 200 is described.

[0084] Figure 3 This is a diagram showing an example of a cigarette.

[0085] Reference Figure 3 Cigarette 200 includes a tobacco stick 210 and a filter stick 220. (See above for reference.) Figure 1 and Figure 2 The first part of the description may include a tobacco stick 210, and the second part may include a filter stick 220.

[0086] The filter rod 220 may include one or more segments. For example, the filter rod 220 may include a first segment configured to cool the aerosol and a second segment configured to filter specific components included in the aerosol. Furthermore, the filter rod 220 may include at least one segment configured to perform other functions, as needed.

[0087] Cigarette 200 may be packaged by at least one package 240. Package 240 may have at least one opening through which external air can be introduced or internal air can be exhausted. For example, cigarette 200 may be packaged by one package 240. As another example, cigarette 200 may be double-packaged by two or more packages 240. For example, tobacco stick 210 may be packaged by a first package, and filter stick 220 may be packaged by a second package. Furthermore, tobacco stick 210 and filter stick 220, each packaged separately, may be connected to each other, and the entire cigarette 200 may be packaged by a third package. When each of tobacco stick 210 or filter stick 220 comprises multiple segments, each segment may be packaged by a separate package. Furthermore, the entire cigarette 200, comprising multiple segments each packaged separately and connected to each other, may be repackaged by another package.

[0088] The tobacco stick 210 may include aerosol-generating substances. For example, the aerosol-generating substances may include, but are not limited to, at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. Furthermore, the tobacco stick 210 may include other additives such as flavoring agents, humectants, and / or organic acids. Additionally, the tobacco stick 210 may include flavoring liquids, such as menthol or humectants, infused into the tobacco stick 210.

[0089] The tobacco stick 210 can be manufactured in various forms. For example, the tobacco stick 210 can be formed as a sheet or shreds. Furthermore, the tobacco stick 210 can be formed as tobacco shreds, which are formed from small pieces cut from tobacco sheets. Additionally, the tobacco stick 210 can be surrounded by a heat-conducting material. For example, the heat-conducting material can be, but is not limited to, a metal foil such as aluminum foil. For example, the heat-conducting material surrounding the tobacco stick 210 can make the heat transferred to the tobacco stick 210 evenly distributed, and therefore, can increase the thermal conductivity applied to the tobacco stick and can improve the flavor of the tobacco. Furthermore, the heat-conducting material surrounding the tobacco stick 210 can serve as a base heated by an induction heater. Here, although not shown in the figures, in addition to the heat-conducting material surrounding the tobacco stick 210, the tobacco stick 210 may also include an additional base.

[0090] Filter rod 220 may include a cellulose acetate filter. The shape of filter rod 220 is not limited. For example, filter rod 220 may include a cylindrical or tubular rod with a hollow interior. Furthermore, filter rod 220 may include a recessed rod. When filter rod 220 comprises multiple segments, at least one of the segments may have a different shape.

[0091] The filter rod 220 can be configured to generate fragrance. For example, a fragrance liquid can be injected into the filter rod 220, or additional fibers coated with a fragrance liquid can be inserted into the filter rod 220.

[0092] Furthermore, the filter rod 220 may include at least one capsule 230. Here, the capsule 230 may perform the function of generating a fragrance or aerosol. For example, the capsule 230 may have a configuration in which a liquid containing a fragrance substance is encapsulated by a membrane. For example, the capsule 230 may have a spherical or cylindrical shape, but is not limited thereto.

[0093] When the filter rod 220 includes a segment configured to cool the aerosol, the cooling segment may comprise a polymeric material or a biodegradable polymeric material. For example, the cooling segment may comprise pure polylactic acid alone, but the materials used to form the cooling segment are not limited thereto. In some embodiments, the cooling segment may comprise a cellulose acetate filter having multiple pores. However, the cooling segment is not limited to the examples described above, and the cooling segment is not limited as long as it cools the aerosol.

[0094] At the same time, although not in Figure 3 As shown, the cigarette 200 according to an embodiment may further include a front-end filter. The front-end filter may be located on a side of the tobacco stick 210 opposite to the filter rod 220. The front-end filter prevents the tobacco stick 210 from being disassembled outwards and prevents liquefied aerosol from flowing from the tobacco stick 210 into the aerosol generating device during smoking. Figure 1 and Figure 2 In the aerosol generating device 100).

[0095] Figure 4 This is a vertical cross-sectional view of the aerosol generating apparatus according to the embodiment, and Figure 5 This is a vertical cross-sectional view of an aerosol generating apparatus according to another embodiment.

[0096] Reference Figure 4 and Figure 5 The aerosol generating apparatus 1000 according to the embodiment may include an aerosol generating substance storage device 1100, an atomizer 1200, and an airflow channel 1300. Furthermore, the aerosol generating apparatus 1000 may also include a housing 1500, a processor 1600, and a battery 1700.

[0097] Figure 4 and Figure 5 Some components of the aerosol generating apparatus 1000 are shown. However, those skilled in the art will understand that the aerosol generating apparatus 1000 according to embodiments may also include other components.

[0098] The aerosol generating substance storage device 1100 can store aerosol generating substances and can supply aerosol generating substances to the atomizer 1200 when the aerosol generating device 1000 is used. The aerosol generating substances can be as described above. Figure 1 and Figure 2 The liquid composition described (e.g., liquids containing tobacco substances).

[0099] The aerosol generating substance storage device 1100 may be a space partitioned inside the aerosol generating device 1000, in which an aerosol generating substance, such as a liquid composition, is injected and stored. Furthermore, the aerosol generating substance storage device 1100 may be provided in the form of a cartridge that can be detached from the main body of the aerosol generating device 1000.

[0100] The aerosol generating substance reservoir 1100 can have various shapes. For example, the aerosol generating substance reservoir 1100 can have a hollow shape positioned around the airflow channel, or it can have a cylindrical shape positioned adjacent to the airflow channel 1300. However, the shape of the aerosol generating substance reservoir 1100 is not limited to these, and according to embodiments, the aerosol generating substance reservoir 1100 can be formed into a generally spherical shape, a hemispherical shape, a frustoconical shape, or a polygonal shape, including an internal space for storing aerosol generating substances.

[0101] The atomizer 1200 can atomize aerosol-generating substances by applying energy. The energy generated from the atomizer 1200 can be, for example, thermal energy or vibrational energy. The atomizer 1200 can receive aerosol-generating substances from the aerosol-generating substance storage container 1100 and atomize the aerosol-generating substances.

[0102] For example, the atomizer 1200 can be connected to the aerosol generator reservoir 1100 via an absorber (e.g., a wick). The atomizer 1200 can continuously receive aerosol generators via the absorber and can heat or vibrate the aerosol generators in response to the user's inhalation to generate an aerosol.

[0103] Figure 4 and Figure 5 An embodiment is shown in which the atomizer 1200 is positioned externally to the aerosol generating substance reservoir 1100. However, in another embodiment, the atomizer 1200 may be positioned internally to the aerosol generating substance reservoir 1100 and may operate as a module together with the aerosol generating substance reservoir 1100. For example, the module in which the atomizer 1200 and the aerosol generating substance reservoir 1100 are combined may be... Figure 1 and Figure 2 The vaporizer or cartridge in the middle.

[0104] The atomizer 1200 may be in fluid communication with the airflow passage 1300, which will be described below. The aerosol generated by the atomizer 1200 may be mixed with outside air (hereinafter referred to as "outside air") introduced into the aerosol generating device 1000 from the outside of the aerosol generating device 1000, and may then be discharged to the outside of the aerosol generating device 1000 via the airflow passage 1300.

[0105] The airflow channel 1300 can be in external fluid communication with the atomizer 1200 and the aerosol generating device 1000, allowing external air and aerosol to move through the airflow channel 1300. That is, the airflow channel 1300 may include a channel for discharging aerosol generated by the aerosol generating device 1000 to the outside (e.g., discharge channel 1320) and a channel for introducing external air into the aerosol generating device 1000 (e.g., inflow channel 1310).

[0106] Reference Figure 4 and Figure 5 The airflow passage 1300 may include an inflow passage 1310 and an outlet passage 1320.

[0107] In one embodiment, the inflow channel 1310 may extend from the inflow port 1311 connected to the outside of the aerosol generating device 1000 to the interior of the aerosol generating device 1000. For example, outside air may flow into the inflow channel 1310 via the inflow port 1311, and may then move or flow along the inflow channel 1310 into the interior of the aerosol generating device 1000.

[0108] In one embodiment, the discharge channel 1320 may extend from the interior of the aerosol generating device 1000 to the discharge port 1321. For example, external air introduced into the aerosol generating device 1000 may move or flow along the discharge channel 1320 toward the discharge port 1321.

[0109] In other words, the airflow channel 1300 can form a flow path for external air in the aerosol generating device 1000 by providing a fluid connection between the inlet port 1311 and the outlet port 1321 through the inlet channel 1310 and the outlet channel 1320.

[0110] According to an embodiment, the plurality of inflow channels 1310 can be positioned around the discharge path 1320 located in the approximate central portion of the aerosol generating device 1000, such as... Figure 4 As shown in the figure. However, the structure of the inflow channel 1310 is not limited to this.

[0111] According to another embodiment, such as Figure 5 As shown, an inflow channel 1310 can be positioned near an outlet channel 1320 located near the center of the aerosol generating device 1000.

[0112] When a user inhales into the aerosol generating device 1000, outside air can be introduced into the interior of the aerosol generating device 1000 through the inflow channel 1310, and the aerosol mixed with the outside air can be discharged to the outside of the aerosol generating device 1000 through the discharge channel 1320.

[0113] The aerosol generating apparatus 1000 according to an embodiment may include a channel wall 1400. The channel wall 1400 may define at least a portion of the airflow channel 1300 and physically separate the inflow channel 1310 from the outlet channel 1320.

[0114] For example, assuming a structure in which a smaller cylindrical tube is inserted into a larger cylindrical tube, the space inside the smaller cylindrical tube can correspond to the discharge channel 1320, while the space between the larger and smaller cylindrical tubes can correspond to the inflow channel 1310.

[0115] In this case, the smaller cylindrical tube that divides the space into the inflow channel 1310 and the discharge channel 1320 may correspond to the channel wall 1400. However, this is only an example for a simplified description of the channel wall 1400, and those skilled in the art will understand that the channel wall 1400 can have various structures and shapes.

[0116] One end 1410 (i.e., the downstream end) of the channel wall 1400 may be positioned adjacent to the exterior of the aerosol generating device 1000, and the other end 1420 (i.e., the upstream end) of the channel wall 1400 may be positioned adjacent to the atomizer 1200.

[0117] Figure 4 and Figure 5 The channel wall 1400 is shown extending in a straight line, but the channel wall 1400 may have a curved shape or an angled shape depending on the embodiment.

[0118] For example, with Figure 4 Unlike the U-shaped airflow channel 1300 shown, when the inlet port 1311 is positioned on the side of the housing 1500 and the outlet port 1321 is positioned on the downstream end of the aerosol generating device 1000, the channel wall 1400 can form an L-shaped airflow channel 1300. That is, the channel wall 1400 can be implemented in various structures depending on the position and shape of the inlet channel 1310 and the outlet channel 1320, and the implementation is not limited to the structure shown.

[0119] The names 1310 and 1320 are used only for ease of description of the implementation, and regardless of the names, air and / or aerosols can move in another direction depending on physical conditions (e.g., pressure gradient). For example, when the user is not inhaling, the air and aerosols present in the aerosol generating device 1000 can move along the inflow channel 1310 to the outside of the aerosol generating device 1000.

[0120] The housing 1500 can form the overall appearance of the aerosol generating device 1000 and can house the aerosol generating substance storage 1100, atomizer 1200, airflow channel 1300, processor 1600 and battery 1700 to protect these components from external impacts.

[0121] According to an embodiment, the aerosol generating device 1000 may include a housing 1500 that includes an inlet port 1311 for external air to flow in and an outlet port 1321 for discharging the aerosol generated by the atomizer 1200 to the outside. For example, the airflow channel 1300 may be a channel connecting the inlet port 1311 to the outlet port 1321.

[0122] Here, the inlet hole 1311 and / or the outlet hole 1321 may be holes formed in the housing 1500, or gaps formed between the elements of the housing 1500.

[0123] According to an embodiment, the aerosol generating device 1000 may further include a mouthpiece. One end of the mouthpiece may contact the user's mouth, and the other end of the mouthpiece may be disposed in the exhaust channel 1320, so that when the user inhales, the aerosol in the exhaust channel 1320 may be discharged to the outside through the mouthpiece.

[0124] The mouthpiece can be manufactured integrally with the housing 1500 or can be a separate configuration that can be detached from the housing 1500.

[0125] The processor 1600 can be electrically connected to the atomizer 1200, the battery 1700, and various sensors (not shown), enabling the processor 1600 to receive and send signals and control the operation of the components. For example, the processor 1600 can control the operation of the atomizer 1200 to adjust the atomization amount according to a preset control algorithm.

[0126] Furthermore, the processor 1600 can detect the user's inhalation via a vaping detection sensor (not shown), and thus can control the operating time and intensity of the atomizer 1200. A detailed description of the processor will be provided below. Figure 8 To provide.

[0127] Battery 1700 can supply the power required for the operation of aerosol generating device 1000. For example, battery 1700 can supply the power required for the operation of processor 1600, atomizer 1200 and various sensors (not shown).

[0128] A more detailed description of the conventional configuration included in the aerosol generating device 1000 will be provided below. Figure 11 To provide.

[0129] Figure 6A and Figure 6B This shows an enlarged cross-sectional view of the airflow channel, in order to illustrate the... Figure 4 The flow of airflow in the aerosol generating apparatus of the embodiment shown in the illustration will be described.

[0130] Figure 6A and Figure 6B An aerosol generating substance storage device 1100, an airflow passage 1300, and an atomizer 1200, including those in an aerosol generating apparatus 1000 according to an embodiment, are shown.

[0131] The airflow passage 1300 may include an inflow passage 1310 and an outlet passage 1320, in which external air flows toward the atomizer 1200, and air and aerosol flow toward the outside of the aerosol generating device 1000 in the outlet passage 1320. A passage wall 1400 may be used to divide the airflow passage 1300 into the inflow passage 1310 and the outlet passage 1320.

[0132] According to an embodiment, the channel wall 1400 may have a hollow shape with an outlet channel 1320 formed therein. Specifically, the outlet channel 1320 may be surrounded by the channel wall 1400, and the inflow channel 1310 may be positioned between at least a portion of the channel wall 1400 and another component of the aerosol generating device 1000.

[0133] like Figure 6A and Figure 6B As shown, the channel wall 1400 may have a cylindrical structure including a cavity, and the inflow channel 1310 may be formed in the space between the outer wall 1110 of the aerosol generating substance reservoir 1100 and the channel wall 1400. The discharge channel 1320 may be formed in the interior space of the channel wall 1400.

[0134] In this case, the outer wall 1110 of the aerosol generating substance reservoir 1100 may correspond to the other component of the aerosol generating device 1000 described above. Here, the outer wall 1110 may refer to the outer surface of the aerosol generating substance reservoir 1100. Furthermore, although not shown, at least a portion of the outer wall 1110 may have a curved shape.

[0135] The aerosol generating apparatus 1000 according to the embodiment may further include an atomizing space 1360. The atomizing space 1360 may refer to the space from which aerosol is ejected from the atomizer 1200. The aerosol generated by the atomizer 1200 can move to the atomizing space 1360, can mix with external air introduced via the inflow channel 1310, and can be discharged to the outside of the aerosol generating apparatus 1000 via the discharge channel 1320.

[0136] The atomizer 1200 atomizes the aerosol-generating material into an aerosol by heating it at approximately 150°C to approximately 250°C. The atomized aerosol can mix with outside air, and the temperature of the atomized aerosol can be reduced to approximately 50°C to approximately 70°C.

[0137] As the temperature decreases, the aerosol may liquefy and / or condense before being expelled from the aerosol generating device 1000. Because liquefied and / or condensed aerosols are adhesive, they may adhere to or accumulate in the atomization space 1360 and the airflow channel 1300. This may reduce the durability of the aerosol generating device 1000 and the user's smoking satisfaction and convenience.

[0138] In other words, allowing aerosols to be rapidly discharged before they liquefy within the aerosol generating device 1000 can improve the durability of the aerosol generating device 1000 and the user's smoking satisfaction.

[0139] The following description will describe the structure in which the aerosol generated in the atomization space 1360 is discharged more quickly to the outside of the aerosol generating device 1000 so as to prevent the liquefied aerosol from adhering to or accumulating in the aerosol generating device 1000.

[0140] The aerosol generating device 1000 may include at least one Coanda surface on which fluids (e.g., introduced external air, aerosols) within the aerosol generating device 1000 are directed to the outside of the aerosol generating device 1000.

[0141] According to an embodiment, the aerosol generating apparatus 1000 may include a first Coanda surface 1430 that protrudes from at least a region of the channel wall 1400 in a direction toward the discharge channel 1320. The term "Coanda surface" refers to a convex surface that guides aerosols to the outside by utilizing the Coanda effect. Here, the Coanda effect refers to the tendency of fluid to move along a curved surface rather than continuing in a straight line.

[0142] In detail, the aerosol generating apparatus 1000 may include a first coda surface 1430 projecting from the channel wall 1400 toward the discharge channel 1320. For example, the first coda surface 1430 may project from the upstream end 1420 of the channel wall 1400 in a direction toward the discharge channel 1320.

[0143] For example, the first Coanda surface 1430 may be convex or curved with a certain curvature.

[0144] Reference Figure 6ABased on the user's intake of the exhaust channel 1320, external air can be introduced into the airflow channel 1310 through the inlet port 1311 and can move to the atomization space 1360. The introduced air can mix with the aerosol in the atomization space 1360.

[0145] Reference Figure 6B When the aerosol mixed with outside air moves into the interior of the exhaust channel 1320, the Coanda effect can occur on the Coanda surface. That is, the aerosol generated in the atomizer 1200 can be guided from the first Coanda surface 1430 toward the exhaust channel 1320 according to the Coanda effect. As a result, the aerosol can move along the surface of the exhaust channel 1320, and the exhaust flow of the aerosol can be accelerated or enhanced.

[0146] Furthermore, the aerosol generating apparatus 1000 may include an exhaust channel 1320 that becomes larger along the discharge direction of the generated aerosol. For example, the cross-sectional area A1 of the inlet 1323 of the exhaust channel 1320 may be smaller than the cross-sectional area A2 of the middle portion 1322 of the exhaust channel 1320.

[0147] It is known that the Coanda effect can occur more effectively in high-speed fluids (e.g., jets). The discharge channel 1320 with the above-described structure accelerates the flow of aerosols at the inlet 1323, thereby enhancing the Coanda effect and thus accelerating the discharge flow of aerosols.

[0148] Additionally, the aerosol generating apparatus 1000 may include an inflow channel 1310 that narrows along the direction in which external air is introduced. For example, the cross-sectional area A3 of the portion 1313 near the atomization space 1360 may be smaller than the cross-sectional area A4 of the portion 1312 near the inflow hole 1311. Therefore, the flow of aerosol moving from the inflow channel 1310 toward the first Coanda surface 1430 can be accelerated, thereby enhancing the Coanda effect.

[0149] Furthermore, it is known that the Coanda effect occurs more effectively on curved surfaces than on flat surfaces. Therefore, when the first Coanda surface 1430 has a convex shape, the aerosol generated by the atomizer 1200 can be discharged to the outside of the aerosol generating device 1000 more quickly.

[0150] According to the above embodiment, the aerosol generated by the atomizer 1200 can move along the first coda surface 1430 in the airflow channel 1300 and can be discharged to the outside of the aerosol generating device 1000 more quickly. Therefore, liquefaction of aerosols within the aerosol generating device 1000 and accumulation of liquefied aerosols can be prevented.

[0151] Figure 7This is an enlarged cross-sectional view of an aerosol generating apparatus according to another embodiment.

[0152] Reference Figure 7 According to another embodiment, the aerosol generating apparatus 1000 may include an aerosol generating substance storage device 1100, an atomizer 1200, and a first coda surface 1430 and a second coda surface 1440 formed on the channel wall 1400.

[0153] Some components of the aerosol generating apparatus 1000 according to this embodiment can be connected with... Figure 4 and Figure 5 The components of the aerosol generating apparatus 1000 shown are the same or similar, and repeated descriptions of these components will be omitted below.

[0154] The aerosol generating apparatus 1000 according to this embodiment may further include a second coda surface 1440, which protrudes from the inner surface of the channel wall 1400 toward the discharge channel 1320. For example... Figure 7 As shown, the second Coanda surface 1440 can be separated from the first Coanda surface 1430.

[0155] The second coda surface 1440 may be located downstream of the first coda surface 1430 relative to the aerosol discharge direction. The second coda surface 1440 may be a curved surface of the discharge channel 1320 projecting in an inward direction.

[0156] The second Coanda surface 1440 can accelerate the flow of air moving downstream in the exhaust channel 1320. By adding the second Coanda surface 1440, the Coanda effect can be enhanced, and aerosols in the exhaust channel 1320 can be discharged more quickly.

[0157] Reference Figure 7 The second coda surface 1440 is formed only in approximately the middle of the discharge channel 1320. However, this is only an example, and multiple second coda surfaces 1440 can be formed to be spaced apart from each other by a certain distance along the longitudinal direction of the discharge channel 1320. That is, the position and number of the second coda surfaces 1440 are not limited to the example shown.

[0158] Furthermore, the discharge channel 1320 can become narrower along the direction in which the aerosol is discharged. For example, the cross-sectional area of ​​the downstream portion of the discharge channel 1320 (e.g., A5) can be smaller than the cross-sectional area of ​​the upstream portion of the discharge channel 1320 (e.g., A6). Therefore, the flow of aerosol moving toward the second Coanda surface 1440 can be accelerated, thereby enhancing the Coanda effect and accelerating the discharge flow of the aerosol.

[0159] Figure 8This is an enlarged cross-sectional view of an aerosol generating apparatus according to another embodiment.

[0160] Reference Figure 8 The aerosol generating apparatus 1000 according to the embodiment may include an aerosol generating substance storage container 1100, an atomizer 1200, and a first coda surface 1430 and a third coda surface 1450 formed on the channel wall 1400. In the following text, the terms "aerosol generating substance storage container 1100", "atomizer 1200", and "atomizer 1450" will be omitted. Figure 4 and Figure 5 The description is a repetitive description.

[0161] Even when the aerosol generating device 1000 is not in use, aerosols can be generated by the residual heat in the atomizer 1200. The aerosol generated by the residual heat may liquefy within the aerosol generating device 1000 and may adhere to the atomization space 1360 and the airflow channel 1300. In this respect, the fluid (or aerosol) in the aerosol generating device 1000 needs to be directed to the outside.

[0162] The aerosol generating apparatus 1000 according to this embodiment may include a third coda surface 1450 that protrudes from at least one region of the channel wall 1400 in a direction toward the inflow channel 1310.

[0163] In detail, the aerosol generating apparatus 1000 may include a third coda surface 1450 projecting from the upstream end 1420 of the channel wall 1400 in a direction toward the interior of the inflow channel 1310. For example, the first coda surface 1430 and the third coda surface 1450 may project from the channel wall 1400 in opposite directions.

[0164] Reference Figure 8 The third coda surface 1450 is formed only at the intersection of the inflow channel 1310 and the atomization space 1360. However, this is only an example, and according to another embodiment, multiple third coda surfaces 1450 can be formed to be spaced apart from each other within the inflow channel 1310 along the direction extending from the inflow channel 1310. That is, the position and number of the third coda surfaces 1450 are not limited to the embodiment shown.

[0165] Reference Figure 8 The diagram illustrates the flow of aerosols generated by waste heat. The third coda surface 1450, together with the first coda surface 1430, allows residual aerosols to be guided to the outside of the aerosol generating device 1000 via the airflow channel 1300.

[0166] In other words, even when the user of the aerosol generating device 1000 is not inhaling, the aerosol in the atomizing space 1360 can be guided along the first coda surface 1430 to the discharge channel 1320, and along the third coda surface 1450 to the inflow channel 1310. Therefore, the aerosol generated by the residual heat can be discharged to the outside of the aerosol generating device 1000.

[0167] In this way, even without a pressure gradient caused by human intervention or coercion (such as inhalation by a user), the first Coanda surface 1430 and the third Coanda surface 1450 can induce an aerosol discharge flow, allowing the aerosol generated by residual heat to be discharged to the outside of the aerosol generating device 1000.

[0168] Figure 9 This is an enlarged view of a mesh arranged in an aerosol generating apparatus according to an embodiment.

[0169] Reference Figure 9 According to the embodiments, the aerosol generating apparatus 1000 may include an aerosol generating substance storage device 1100, an atomizer 1200, an airflow channel 1300, and a mesh M. Figure 9 It can be that the mesh M is added to Figure 4 The embodiment of the aerosol generating apparatus 1000 shown herein, and in the following text, will be omitted. Figure 4 The aerosol generating apparatus 1000 shown is described repeatedly.

[0170] As described above, a portion of the aerosol that remains in the aerosol generating device 1000 for a relatively long time may liquefy in the airflow channel 1300. When a user inhales the liquefied aerosol, the user's smoking satisfaction may decrease, and therefore, it is necessary to prevent the release of the liquefied aerosol.

[0171] According to an embodiment, the aerosol generating apparatus 1000 may further include a mesh screen M, and the mesh screen M may be arranged in a region of the airflow channel 1300. For example, the mesh screen M may be arranged in the inflow channel 1310 or the outlet channel 1320. In addition, the mesh screen M may be attached to at least one region of the channel wall 1400. However, the embodiment is not limited to this.

[0172] like Figure 9 As shown, the mesh M may include a plurality of holes m through which the mesh M is penetrated. The mesh M can prevent liquefied aerosol A with a size greater than or equal to a certain size from being discharged to the outside of the aerosol generating device 1000 via the airflow channel 1300.

[0173] The diameter of the holes m through which the mesh M passes can be, for example, from 0.2 μm to 15 μm. Assuming a diameter of 15 μm, aerosols with a diameter less than or equal to 15 μm can be discharged to the outside of the aerosol generating device 1000. However, in this case, liquefied aerosols with a diameter greater than 15 μm can be prevented from being discharged to the outside of the aerosol generating device 1000.

[0174] Figure 10 This is a cross-sectional view of an aerosol generating apparatus according to another embodiment.

[0175] Reference Figure 10 According to another embodiment, the aerosol generating device 1000 may include an aerosol generating substance storage device 1100, an atomizer 1200, an airflow channel 1300, a processor 1600, a battery 1700, a heating element 1800, and a suction detection sensor 1900.

[0176] Figure 10 The aerosol generating device 1000 can be made by adding a heating element 1800 and a suction detection sensor 1900 to... Figure 4 An embodiment of the aerosol generating apparatus 1000 is described. Therefore, details related to... Figure 4 The description of the aerosol generating device 1000 is repeated.

[0177] The heating element 1800 may be arranged on the channel wall 1400 and may apply heat to the fluid or aerosol present in the aerosol generating device 1000. For example, the heating element 1800 may be arranged in a specific region (e.g., the middle region) of the channel wall 1400 and may apply heat to the aerosol flowing along the discharge channel 1320.

[0178] Specifically, the heating element 1800 can heat the airflow passing through the airflow channel 1300 and the aerosol adhering to the airflow channel 1300, thereby promoting the movement or discharge of the aerosol.

[0179] In other words, the heating element 1800 can re-vaporize the adhered aerosol or atomize the condensed aerosol, so that the aerosol is discharged to the outside of the aerosol generating device 1000.

[0180] Reference Figure 10 The heating element 1800 has the shape of a coil mounted within and in a generally central region of the channel wall 1400. However, the implementation is not limited to this shape and structure. For example, the heating element 1800 may be wound around the surface of the channel wall 1400, may have a plate shape or a cylindrical shape, or may be arranged on the upstream or downstream end of the channel wall 1400.

[0181] The heating element 1800 can be a resistance heater or an induction heater. However, the implementation is not limited to a specific heating method.

[0182] The inhalation detection sensor 1900 can detect the user's inhalation of aerosols while using the aerosol generating device 1000. (See reference...) Figure 10 The suction detection sensor 1900 can be arranged on the channel wall 1400. However, the implementation is not limited to this, and the suction detection sensor 1900 can be arranged at another location where changes in airflow can be detected.

[0183] The processor 1600 can be electrically connected to the heating element 1800 and the suction detection sensor 1900, enabling the processor 1600 to control the operation of the heating element 1800 based on signals detected by the suction detection sensor 1900. Specifically, the processor 1600 can receive signals from the suction detection sensor 1900 and, upon receiving a suction signal, can control the heating element 1800 to be heated for a certain period of time. For example, the heating temperature of the heating element 1800 can be approximately 50°C to approximately 80°C, and the certain period of time can be 5 seconds. The heating temperature and heating time can be varied according to user settings.

[0184] Since the heating element 1800 is also included in the aerosol generating device 1000, the airflow channel 1300 can be maintained at a certain temperature when the aerosol generating device 1000 is used. Therefore, the discharge of aerosols can be accelerated.

[0185] Furthermore, even when the use of the aerosol generating device 1000 is terminated, the airflow channel 1300 can remain heated for a certain period of time. As a result, it is possible to prevent the aerosol from liquefying within the aerosol generating device 1000, and to prevent the liquefied aerosol from adhering to or accumulating in the airflow channel 1300.

[0186] Additionally, the aerosol generating article 2000 can be inserted into the aerosol generating apparatus 1000. The aerosol generating article 2000 can be, for example, as described above. Figures 1 to 3 The cigarettes described.

[0187] The aerosol generating article 2000 can be formed with a shape corresponding to the exhaust channel, so that the aerosol generating article 2000 can be inserted into the aerosol generating device 1000. The user can contact a portion of the aerosol generating article 2000 with his / her mouth. When the user inhales through the aerosol generating article 2000, the aerosol generated in the atomizer 1200 can pass through the aerosol generating article 2000. As it passes through the aerosol generating article 2000, the aerosol can mix with another aerosol generated from the aerosol generating article 2000, allowing the mixed aerosol to be expelled.

[0188] The aerosol generating article 2000 may include the same aerosol generating substance as that included in the aerosol generating substance reservoir 1100, but the aerosol generating article 2000 may include different substances. For example, the aerosol generating article 2000 may include a fragrance element such that a fragrance can be added to the aerosol generated by the atomizer 1200 as the aerosol passes through the aerosol generating article 2000.

[0189] The heating element 1800 can also heat the aerosol generating article 2000 inserted into the aerosol generating apparatus 1000. For example, the heating element 1800 can correspond to a reference. Figure 1 and Figure 2 The heater described.

[0190] Figure 11 This is a block diagram of an aerosol generating apparatus according to an embodiment.

[0191] Reference Figure 11 The aerosol generating device 1000 may include a battery 1010, an atomizer 1020, a sensor 1030, a user interface 1040, a memory 1050, and a processor 1060. However, the internal structure of the aerosol generating device 1000 is not limited to... Figure 11 The illustration is shown. Those skilled in the art will understand that, based on the design of the aerosol generating device 1000, it can... Figure 11 Some of the hardware components shown may be omitted or may include new configurations.

[0192] In one embodiment, the aerosol generating apparatus 1000 may include a main body. In this case, the hardware components included in the aerosol generating apparatus 1000 may be positioned within the main body.

[0193] In another embodiment, the aerosol generating device 1000 may include a body and a cartridge. Hardware components included in the aerosol generating device 1000 may be located in the body and / or the cartridge. Alternatively, at least a portion of the hardware components included in the aerosol generating device 1000 may be located in each of the body and the cartridge.

[0194] In the following description, the operation of each element will be described without limiting the space in which each element is located among the elements included in the aerosol generating apparatus 1000.

[0195] Battery 1010 provides power for operating the aerosol generating device 1000. Specifically, battery 1010 supplies power so that atomizer 1020 can atomize the aerosol-generating material. Additionally, battery 1010 provides power for the operation of other hardware components included in the aerosol generating device 1000, namely sensor 1030, user interface 1040, memory 1050, and processor 1060. Battery 1010 can be a rechargeable battery or a disposable battery.

[0196] For example, battery 100 may include a nickel-based battery (e.g., nickel-metal hydride battery, nickel-cadmium battery) or a lithium-based battery (e.g., lithium-cobalt battery, lithium phosphate battery, lithium titanate battery, lithium-ion battery, or lithium polymer battery). However, the types of batteries 1010 that can be used in aerosol generating apparatus 1000 are not limited to those described above. Depending on the need, battery 1010 may include an alkaline battery or a manganese battery.

[0197] The atomizer 1020 can receive power from the battery 1010 under the control of the processor 1060. The atomizer 1020 can atomize the aerosol generating substances stored in the aerosol generating device 1000 by receiving power from the battery 1010.

[0198] The atomizer 1020 may be located within the main body of the aerosol generating device 1000. Alternatively, when the aerosol generating device 1000 comprises a main body and a cartridge, the atomizer 1020 may be located within the cartridge or within both the main body and / or the cartridge. When the atomizer 1020 is located within the cartridge, the atomizer 1020 may receive power from a battery 1010 located in at least one of the main body and the cartridge.

[0199] Furthermore, when the atomizer 1020 is located in each of the main body and the cartridge, the power-requiring components of the atomizer 1020 can receive power from the battery 1010 located in at least one of the main body and the cartridge.

[0200] The atomizer 1020 can generate aerosols from aerosol-generating substances within the cartridge. An aerosol is a suspension of liquid and / or solid fine particles dispersed in a gas. Therefore, the aerosol generated by the atomizer 1020 can refer to the state in which vaporized particles generated from the aerosol-generating substances are mixed with air.

[0201] For example, the atomizer 1020 can transform the phase of the aerosol generating substance into a gaseous phase through vaporization and / or sublimation. Furthermore, the atomizer 1020 can generate aerosols by atomizing and ejecting aerosol generating substances that are in a liquid and / or solid phase.

[0202] For example, the atomizer 1020 can generate aerosols from aerosol-generating substances using an ultrasonic vibration method. The ultrasonic vibration method can refer to a method of generating aerosols by atomizing aerosol-generating substances through ultrasonic vibrations generated by a vibrator.

[0203] although Figure 11 Not shown, but the atomizer 1020 may optionally include a heater for heating the aerosol-generating material. The aerosol-generating material can be heated by the heater. As a result, an aerosol can be generated.

[0204] The heater can be formed from any suitable resistive material. For example, suitable resistive materials can 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, or nickel-chromium alloys. Furthermore, the heater can be implemented as a metal heating wire, a metal heating plate with conductive traces arranged thereon, a ceramic heating element, etc. However, the implementation is not limited to these.

[0205] For example, in one embodiment, the heater may be part of the cartridge, and the heater may be included in the body of the aerosol generating device. Furthermore, the cartridge may include a reservoir and / or an absorber, and / or the body may include a receiver and / or an absorber.

[0206] For example, aerosol-generating material contained in the receiver can move to the absorber, and a heater can heat the aerosol-generating material absorbed by the absorber to generate aerosols. For example, the heater can be wrapped around the absorber or positioned adjacent to the absorber.

[0207] The heater may be an induction heater. The heater may include a conductive coil for heating the aerosol-generating substance using an induction heating method, and the base that can be heated by the induction heater may be included in the cartridge and / or body.

[0208] The aerosol generating device 1000 may include at least one sensor 1030. The results sensed by the at least one sensor 1030 may be transmitted to a processor 1060. Based on the sensing results, the processor 1060 may control the aerosol generating device 1000 to perform various functions such as controlling the operation of the atomizer 1020, restricting smoking, determining whether a cartridge (or cigarette) is inserted, and displaying notifications.

[0209] For example, at least one sensor 1030 may include a suction detection sensor. The suction detection sensor may detect the user's suction based on at least one of the following: changes in the flow rate of air introduced from the outside; pressure changes; and sound detection. The suction detection sensor may detect the start and end times of the user's suction, and the processor 1060 may determine suction periods and non-suction periods based on the determined start and end times.

[0210] Furthermore, at least one sensor 1030 may include a user input sensor. The user input sensor can be a sensor capable of receiving user input, such as a switch, physical button, touch sensor, etc. For example, the touch sensor may be a capacitive sensor; when a user touches a specific area formed of a metallic material, a change in capacitance occurs, and the capacitive sensor detects this change in capacitance to detect user input. The processor 1060 can determine whether user input has occurred by comparing the value received from the capacitive sensor before the capacitance change with the value after the capacitance change. When the value before the capacitance change and the value after the capacitance change exceed a preset threshold, the processor 1060 can determine that user input has occurred.

[0211] Furthermore, at least one sensor 1030 may include a consumable removal sensor capable of detecting the installation or removal of consumables (e.g., cartridges, cigarettes, etc.) that can be used in the aerosol generating apparatus 1000. For example, the consumable removal sensor may use an image sensor to determine whether a consumable is in contact with the aerosol generating apparatus 1000 or whether a consumable has been removed. Alternatively, the consumable removal sensor may be an inductive sensor that detects changes in the inductance of a coil that can interact with a mark on the consumable, or a capacitive sensor that detects changes in the capacitance of a capacitor that can interact with a mark on the consumable.

[0212] In addition, at least one sensor 1030 may include a temperature sensor. The temperature sensor can detect the temperature at which the heater (or aerosol generating substance) of the atomizer 1020 is heated. The aerosol generating device 1000 may include a separate temperature sensor for detecting the temperature of the heater, or the heater itself may be used as a temperature sensor instead of a separate temperature sensor. Alternatively, the heater may be used as a temperature sensor, and the aerosol generating device 1000 may also include a separate temperature sensor. Furthermore, in addition to the heater, the temperature sensor may also detect the temperature of internal components of the aerosol generating device 1000, such as a printed circuit board (PCB), a battery, etc.

[0213] Furthermore, at least one sensor 1030 may include various sensors for measuring information about the surrounding environment of the aerosol generating device 1000. For example, at least one sensor 1030 may include a temperature sensor for measuring the temperature of the surrounding environment, a humidity sensor for measuring the humidity of the surrounding environment, an atmospheric pressure sensor for measuring the pressure of the surrounding environment, etc.

[0214] The sensor 1030, which can be installed in the aerosol generating device 1000, is not limited to the types described above and may include various other sensors.

[0215] The aerosol generating apparatus 1000 may optionally select and implement only some of the examples of the various sensors 1030 described above. In other words, the aerosol generating apparatus 1000 can be used by combining multiple pieces of information sensed by at least one of the aforementioned sensors.

[0216] User interface 1040 can provide users with information about the status of aerosol generating device 1000. User interface 1040 may include various interface units, such as a display or light for outputting visual information, a motor for outputting tactile information, a speaker for outputting sound information, terminals for data communication with input / output (I / O) interface units (e.g., buttons or touch screens) for receiving or outputting information from or to the user, or for receiving charging power from I / O interface units, and communication interface modules for wireless communication with external devices (e.g., Wi-Fi, Wi-Fi Direct, Bluetooth, Near Field Communication (NFC), etc.).

[0217] However, the aerosol generating apparatus 1000 may select and implement only a few of the above-mentioned examples of various examples of the user interface 1040.

[0218] The memory 1050, which serves as hardware for storing various data processed in the aerosol generating apparatus 1000, can store data that has been processed by or is to be processed by the processor 1060. The memory 1050 can be implemented in various types, such as: random access memory (RAM), for example dynamic random access memory (DRAM), static random access memory, etc.; read-only memory (ROM); electrically erasable programmable read-only memory (EEPROM), etc.

[0219] The memory 1050 can store data about the operating time of the aerosol generating device 1000, the maximum number of puffs, the current number of puffs, at least one temperature profile, and the user's smoking pattern.

[0220] The processor 1060 can control the overall operation of the aerosol generating device 1000. The processor 1060 can be implemented as an array of multiple logic gates or as a combination of a general-purpose microprocessor and a memory storing a program to be executed by the microprocessor. Furthermore, those skilled in the art will understand that the processor 1060 can be implemented in another type of hardware.

[0221] The processor 1060 can analyze the results sensed by at least one sensor 1030 and control the processing to be performed.

[0222] The processor 1060 can control the power supplied to the atomizer 1020 based on the results sensed by at least one sensor 1030, so that the operation of the atomizer 1020 can be started or stopped. Furthermore, the processor 1060 can control the amount of electricity supplied to the atomizer 1020 and the duration of the power supply based on the results sensed by at least one sensor 1030, so that the atomizer 1020 can generate an appropriate amount of aerosol. For example, the processor 1060 can control the current or voltage supplied to the vibrator, so that the vibrator of the atomizer 1020 can vibrate at a certain frequency.

[0223] In this implementation, the processor 1060 can receive user input regarding the aerosol generating device 1000 and then initiate operation of the atomizer 1020. Furthermore, the processor 1060 can detect user inhalations using a puff detection sensor and then initiate operation of the atomizer 1020. Additionally, the processor 1060 can count the number of puffs using the puff detection sensor, and when the number of puffs reaches a preset number, it can stop the power supply to the atomizer 1020.

[0224] The processor 1060 can control the user interface 1040 based on the results sensed by at least one sensor 1030. For example, when the number of aspirations is counted by using a suction detection sensor and the number of aspirations reaches a preset number, the processor 1060 can notify the user that the aerosol generating device 1000 is about to terminate by using at least one of a light, a motor, and a speaker.

[0225] Those skilled in the art related to this embodiment will understand that various changes in form and detail can be made to the embodiment without departing from the scope of the above features. The disclosed methods should be considered in a descriptive sense only and not for limiting purposes. The scope of this disclosure is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents of the claims should be interpreted as included in this disclosure.
