[0041] The present disclosure will now be described more fully below with reference to the accompanying drawings, which illustrate exemplary embodiments of the disclosure to enable those skilled in the art to readily implement it. However, the disclosure may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0042] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0043] Figure 1 This is a schematic diagram of the structure of the aerosol-generating article 100 according to the embodiment.

[0044] Reference Figure 1 The aerosol generating article 100 may include a first part 110, a second part 120, a third part 130, and a fourth part 140. Specifically, the first part 110, the second part 120, the third part 130, and the fourth part 140 may each include an aerosol generating element, a cooling element, a tobacco element, and a filter element, respectively. For example, the first part 110 may include an aerosol generating material, the second part 120 may cool the aerosol passing through the first part 110, the third part 130 may include tobacco material and a humectant, and the fourth part 140 may include a filter material.

[0045] Reference Figure 1 The first portion 110, the second portion 120, the third portion 130, and the fourth portion 140 can be arranged sequentially along the longitudinal direction of the aerosol generating article 100. Here, the longitudinal direction of the aerosol generating article 100 can be the direction in which the aerosol generating article 100 extends along its length. For example, the longitudinal direction of the aerosol generating article 100 can be from the first portion 110 toward the fourth portion 140. Therefore, aerosol generated from at least one of the first portion 110 and the second portion 120 can sequentially pass through the third portion 130 and the fourth portion 140, and the smoker can absorb the aerosol from the fourth portion 140.

[0046] Typically, aerosol generating elements have a vaporization temperature of approximately 140°C to approximately 250°C, while nicotine contained in tobacco elements has a vaporization temperature of approximately 50°C to approximately 90°C. In other words, aerosol generating elements generally have a higher vaporization temperature than nicotine.

[0047] In most aerosol-generating articles according to the prior art, the portion comprising the aerosol-generating element and the portion comprising the tobacco element are arranged adjacent to each other. In this case, when the aerosol-generating element is heated to a high temperature by the aerosol-generating device, the tobacco element arranged adjacent to the aerosol-generating element may also be heated to an unnecessarily high temperature. Therefore, from the initial smoking stage, excessive nicotine is transferred from the tobacco element, causing the nicotine in the tobacco element to be depleted prematurely. As a result, the amount of nicotine transferred decreases significantly in the later stages of smoking, making it difficult to achieve uniform nicotine inhalation throughout the smoking time.

[0048] Here, the early stages of smoking—such as the first half of the smoking time—can correspond to the “initial smoking stage,” and the remainder of the smoking time can correspond to the “late smoking stage.”

[0049] In the aerosol-generating article according to an embodiment, a second portion 120 including a cooling element is arranged between a first portion 110 including an aerosol-generating element and a third portion 130 including a tobacco element. Therefore, the high-temperature aerosol generated in the first portion 110 is cooled by the cooling element of the second portion 120 and then passes through the third portion 130. The tobacco element in the third portion 130 is heated by the aerosol having a relatively low temperature, thereby enabling uniform nicotine inhalation throughout the smoking time.

[0050] As will be described below, the first portion 110 of the aerosol generating article 100 can be directly heated by the heater of the aerosol generating device, while the third portion 130 may not be directly heated. For example, when the aerosol generating article 100 is inserted into the aerosol generating device, the first portion 110 may be surrounded by the heater, while the third portion 130 may not be surrounded by the heater. Here, the heater may be arranged to surround at least a portion of the accommodating space containing the aerosol generating article 100. The tobacco element included in the third portion 130 can be heated by the aerosol generated in the first portion 110 and passing through the third portion 130 at a higher temperature. Because the third portion 130 is not directly heated by the heater, the temperature deviation occurring in the third portion 130 can be reduced compared to the case where the third portion 130 is directly heated by the heater (i.e., at least a portion of the third portion 130 is surrounded by the heater). Therefore, the amount of nicotine inhaled throughout the smoking time can remain uniform.

[0051] The first portion 110 may include an aerosol generating element. Furthermore, the first portion 110 may contain other additives, such as flavoring agents, wetting agents, and / or organic acids, or the first portion 110 may contain flavor liquids, such as menthol or humectants. Here, the aerosol generating element may include at least one of, for example, glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, this disclosure is not limited to the above examples and may include any other type of aerosol generating element known in the art.

[0052] Part 110 may include a rolled sheet containing (e.g., impregnated) an aerosol generating element. Additionally, the rolled sheet may include other additives such as flavoring agents, wetting agents, and / or organic acids, as well as flavor liquids.

[0053] Curled sheets can include at least one of, for example, paper, cellulose acetate, lyocell fiber, and polylactic acid. For example, a curled sheet can be a paper sheet that does not emit an odor even when heated to a high temperature. However, it is not limited to this.

[0054] The first portion 110 may extend from the end of the aerosol-generating article 100 by about 7 mm to about 20 mm. However, the first portion 110 is not necessarily limited to this range, and the length of the first portion 110 may be appropriately adjusted according to the embodiment.

[0055] The second portion 120 can cool the flow (i.e., aerosol) passing through the first portion 110. The second portion 120 can be formed of a polymeric or biodegradable polymeric material and can have a cooling function. For example, the second portion 120 can be formed of polylactic acid (PLA) fibers, but is not limited thereto. Alternatively, the second portion 120 can be formed of a cellulose acetate filter having multiple pores. However, the second portion 120 is not limited to the examples described above and can include any material capable of cooling the aerosol. For example, the second portion 120 can include a tubular filter or a paper tube including a cavity.

[0056] The second part 120 may include a tubular structure including a cavity, and the inner surface of the cavity may be coated with PLA and / or flavoring material.

[0057] PLA can be coated on the inner surface of the second part 120 and can effectively cool the aerosol through phase change. For example, PLA can undergo phase change, such as melting or glass transition, by absorbing thermal energy. The thermal energy of the aerosol passing through the inner surface of the cavity can be used for the phase change of PLA, thereby effectively reducing the temperature of the aerosol.

[0058] Flavoring materials can be coated on the inner surface of the cavity and can add flavor to aerosols passing through the inner surface of the cavity. Flavoring materials can refer to materials used to add a specific flavor. For example, flavoring materials can include botanical spices such as cinnamon, sage, vanilla, chamomile, wintergreen, lavender, bergamot, lemon, orange, jasmine, ginger, vanilla, spearmint, peppermint, acacia, coffee, celery, sandalwood, cocoa, etc.

[0059] As another example, flavoring materials can include animal spices such as musk, ambergris, civet cat, castoreum, etc.

[0060] As another example, flavoring materials may include alcohols such as menthol, geraniol, linalool, anethole, eugenol, etc. Additionally, flavoring materials may include aldehydes such as vanillin, benzaldehyde, anisaldehyde, etc. Furthermore, flavoring materials may include esters such as isoamyl acetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc. Preferably, flavoring materials may include menthol.

[0061] The second portion 120 may have a length of about 3 mm to about 30 mm in the longitudinal direction of the aerosol-generating article 100. With the second portion 120 having a length within the aforementioned range, the aerosol generated in the first portion 110 can be cooled to a temperature suitable for vaporizing nicotine from the tobacco element of the third portion 130. When the second portion 120 has a length less than about 3 mm, the aerosol may not be sufficiently cooled. On the other hand, when the second portion 120 has a length greater than about 30 mm, the aerosol may be overcooled and may not have a sufficiently high temperature for vaporizing nicotine. To achieve uniform nicotine inhalation throughout the smoking time, the second portion 120 may preferably have a length of about 3 mm to about 20 mm, and more preferably, a length of about 3 mm to about 15 mm along the longitudinal direction of the aerosol-generating article.

[0062] Part 3, 130, may include tobacco elements. Tobacco elements may include some type of tobacco material. For example, tobacco elements may be included in the form of pipe tobacco, tobacco pellets, tobacco sheets, tobacco beads, tobacco kernels, tobacco powder, or tobacco extract. Furthermore, tobacco material may include at least one of, for example, tobacco leaves, side veins of tobacco leaves, expanded tobacco, shredded tobacco, tobacco sheets, and reconstituted tobacco.

[0063] The fourth part 140 may include a filter material. For example, the fourth part 140 may include a cellulose acetate filter element. The shape of the fourth part 140 is not particularly limited. For example, the fourth part 140 may include a cylindrical rod or a tubular rod. Furthermore, the fourth part 140 may include a recessed rod. When the fourth part 140 includes multiple segments, at least one of the segments may be formed to have a shape different from the other segments.

[0064] The fourth part 140 can be formed to generate a flavor. For example, a liquid flavoring material can be injected into the fourth part 140, or additional fibers impregnated with flavoring material can be inserted into the fourth part 140. For example, the additional fibers impregnated with flavoring material can be arranged parallel to the longitudinal direction of the aerosol generating article 100. The additional fibers impregnated with flavoring material can be formed using materials such as cellulose acetate, cotton, PLA, etc., but are not limited to these. In addition, the amount of flavoring material impregnated can be controlled by adjusting the fiber thickness, the number of fiber strands, etc.

[0065] Furthermore, part 140 may include at least one capsule-like component. For example, the capsule-like component may include a flavoring material, and when the capsule-like component ruptures, the flavoring material can generate a flavor. Additionally, the capsule-like component may include an aerosol-generating material, and when the capsule-like component ruptures, the aerosol-generating material can generate an aerosol. The capsule-like component may have a structure in which the aerosol-generating material is encapsulated by a thin film. The capsule-like component may have a spherical or columnar shape, but is not limited to these.

[0066] The aerosol generating article 100 may include a wrapping element 150 surrounding at least a portion of the first portions 110 to the fourth portions 140. Furthermore, the aerosol generating article 100 may include a wrapping element 150 surrounding the entirety of the first portions 110 to the fourth portions 140. The wrapping element 150 may be the outermost layer of the aerosol generating article 100, and the wrapping element 150 may be a single wrapping element or a combination of multiple wrapping elements.

[0067] For example, the aerosol generating article 100 may further include a heat-conducting wrapping 151 surrounding at least a portion of the first part 110. Here, the heat-conducting wrapping 151 may comprise a material with excellent thermal conductivity, such as a metal. The heat-conducting wrapping 151 may be positioned corresponding to the heater of the aerosol generating apparatus described below, and may comprise a paramagnetic material (e.g., aluminum, platinum, ruthenium, etc.) that is not used as a receptor for induction heating. The heat-conducting wrapping 151 may surround at least a portion of the first part 110, allowing that portion to be directly heated by the aerosol generating apparatus. The heat-conducting wrapping 151 can efficiently transfer heat from the heater to the entire first part 110 due to its high thermal conductivity.

[0068] The package 150 may include at least one perforation through which external air can be introduced into the aerosol-generating article or through which internal air can be exhausted to the outside. For example, the package 150 may surround at least a portion of the second portion 120 and may include at least one first perforation 161 formed at a location corresponding to the second portion 120. External air introduced through the at least one first perforation 161 can effectively cool the aerosol.

[0069] Furthermore, the package 150 may at least partially surround the fourth portion 140 and may include at least one second perforation 162 formed at a location corresponding to the fourth portion 140. External air introduced through this at least one second perforation 162 may cool and dilute the aerosol supplied to the smoker.

[0070] Implementation Method 1: Manufacturing of Aerosol-Generating Products

[0071] The aerosol-generating article is manufactured comprising a first part, a second part, a third part, and a fourth part arranged sequentially along a longitudinal direction. The first part comprises a rolled sheet containing aerosol-generating material, and the second part comprises a tube containing a material capable of cooling the generated aerosol. The third part comprises a tobacco sheet as tobacco material and glycerin as a humectant, and the fourth part comprises cellulose acetate fibers.

[0072] Comparative Example 1: Manufacturing of Aerosol-Generating Products

[0073] The aerosol-generating article is manufactured to include a tobacco stick and a filter rod arranged sequentially along a longitudinal direction. The tobacco stick includes a tube containing tobacco pieces cut into small sizes, and the filter rod includes a cellulose acetate filter element.

[0074] Comparative Example 2: Manufacturing of Aerosol-Generated Products

[0075] The aerosol-generating article is manufactured comprising a front plug, a tobacco stick, and a filter stick arranged sequentially along a longitudinal direction. The front plug is formed using cellulose acetate tow. The tobacco stick and the filter stick are formed using the same method as in Comparative Example 1.

[0076] Comparative Example 3: Manufacturing of Aerosol-Generated Articles

[0077] Except that the positions of the second and third parts of Embodiment 1 are interchanged, the aerosol generating article is manufactured using the same method as Embodiment 1. That is, the aerosol generating article is manufactured to include the first, third, second, and fourth parts of Embodiment 1 arranged sequentially along the longitudinal direction.

[0078] Experimental Implementation Method 1: Analysis of the amount of nicotine inhaled (i.e. transferred) based on the number of puffs.

[0079] The amount of nicotine inhaled based on the number of inhalations was analyzed using the aerosol-generating articles according to Embodiment 1 and Comparative Examples 1 to 3. Specifically, the aerosol-generating articles according to Embodiment 1 and Comparative Examples 1 to 3 were heated, and inhalation was started after the aerosol-generating articles were sufficiently heated. The amount of nicotine inhaled in each inhalation was measured, and the amount of nicotine inhaled in 14 inhalations was measured. The results are as follows: Figure 2 As shown in the image.

[0080] Figure 2 This is a graph showing the amount of nicotine inhaled with each inhalation when smoking is performed using an aerosol-generated article according to the embodiments and comparative examples.

[0081] like Figure 2As shown, for the aerosol-generating article of Comparative Example 1, nicotine was inhaled until the 11th inhalation, and no nicotine inhalation was detected thereafter. Furthermore, for the aerosol-generating articles of Comparative Examples 2 and 3, most of the nicotine was inhaled during the 2nd to 6th inhalations, and the amount of nicotine inhaled thereafter was significantly reduced.

[0082] On the other hand, in the case of the aerosol-generating article according to Embodiment 1, unlike the aerosol-generating articles of Comparative Examples 1 to 3, the amount of nicotine inhaled during a total of 14 inhalations remains relatively uniform.

[0083] Figure 3 This is a view illustrating the components of an aerosol generating apparatus according to an embodiment.

[0084] Reference Figure 3 The aerosol generating device 200 may include a heater 230, a coil 231, a battery 210, and a controller 220. However, the aerosol generating device 200 is not limited to these components, and may also include... Figure 3 Other general-purpose components besides those shown in the diagram.

[0085] The aerosol generating apparatus 200 generates aerosols by heating the aerosol generating article disposed in the aerosol generating apparatus 200 using an induction heating method. The induction heating method can refer to a method of heating a magnetic material by applying an alternating magnetic field that periodically changes direction.

[0086] When an alternating magnetic field is applied to a magnetic material by coil 231, energy loss occurs in the magnetic material due to eddy current loss and hysteresis loss, and this lost energy can be emitted from the magnetic material as heat. As the amplitude or frequency of the alternating magnetic field applied to the magnetic material increases, the amount of heat emitted from the magnetic material also increases. The heat released from the magnetic material can be used to heat the aerosol-generated product.

[0087] Magnetic materials that emit heat via an external magnetic field can be receptors. Receptors included in the aerosol generating apparatus 200 can have magnetic materials in the form of sheets or strips. For example, at least a portion of the heater 230 arranged in the aerosol generating apparatus 200 may include receptor material.

[0088] At least a portion of the receptor material may include a ferromagnetic material. For example, the receptor material may include a metal or carbon. The receptor material may include at least one of ferrite, ferromagnetic alloy, stainless steel, and aluminum. In addition, the receptor material may include ceramic materials (e.g., graphite, molybdenum, silicon carbide, niobium, nickel alloy, metal film, zirconium oxide, etc.), transition metals (e.g., nickel, cobalt, etc.), or nonmetals (i.e., boron or phosphorus).

[0089] The aerosol generating apparatus 200 can contain an aerosol generating article. The aerosol generating apparatus 200 may include a space for containing the aerosol generating article. A heater 230 may be arranged within the space for containing the aerosol generating article. For example, the heater 230 may have a cylindrical placement space for containing the aerosol generating article. Therefore, when the aerosol generating article is contained in the aerosol generating apparatus 200, the aerosol generating article can be contained within the heater 230.

[0090] The heater 230 may surround at least a portion of the outer surface of the aerosol generating article housed in the aerosol generating apparatus 200. For example, the heater 230 may surround tobacco material included in the aerosol generating article. Therefore, heat can be transferred more efficiently from the heater 230 to the tobacco material.

[0091] Heater 230 can heat the aerosol-generating article contained in aerosol generating apparatus 200. As described above, heater 230 can heat the aerosol-generating article by induction heating. Heater 230 may include a heat-sensing material that emits heat in response to an external magnetic field, and aerosol generating apparatus 200 can apply an alternating magnetic field to heater 230.

[0092] Coil 231 can be disposed in aerosol generating apparatus 200. Coil 231 can apply an alternating magnetic field to heater 230. When electricity is supplied from aerosol generating apparatus 200 to coil 231, a magnetic field can be formed in coil 231. When alternating current is applied to coil 231, the direction of the magnetic field formed in coil 231 can be continuously changed. When heater 230 is exposed to the alternating magnetic field in coil 231, heater 230 can emit heat, and the aerosol generating article contained in the accommodating space of heater 230 can be heated.

[0093] The coil 231 can be wound along the outer surface of the heater 230. Alternatively, the coil 231 can be wound along the inner surface of the housing of the aerosol generating device 200. The heater 230 can be located within the internal space of the wound coil 231. When power is supplied to the coil 231, an alternating magnetic field generated by the coil 231 can be applied to the heater 230.

[0094] The coil 231 can extend to an appropriate length along the longitudinal direction of the aerosol generating device 200. For example, the coil 231 can have the same length as the heater 230 or can extend longer than the heater 230.

[0095] The coil 231 can be arranged at a position suitable for applying an alternating magnetic field to the heater 230. For example, the coil 231 can be arranged at a position corresponding to the heater 230, so that the alternating magnetic field of the coil 230 is effectively applied to the heater 230.

[0096] When the amplitude or frequency of the alternating magnetic field formed by coil 231 changes, the degree of heating performed by heater 230 on the aerosol-generating article can also be changed. The amplitude or frequency of the magnetic field generated by coil 231 can be changed according to the power applied to coil 231; therefore, aerosol generating apparatus 200 can regulate the power applied to coil 230 to control the heating of the aerosol-generating article. For example, aerosol generating apparatus 200 can control the amplitude and frequency of the alternating current applied to coil 231.

[0097] For example, coil 231 can be implemented as a solenoid. Coil 231 can be a solenoid wound along the inner surface of the housing of aerosol generating apparatus 200, and heater 230 and aerosol generating article can be located within the interior space of the solenoid. The material of the solenoid can be copper. However, the material of the solenoid is not limited to this, and any one of Ag, Au, Al, W, Zn, and Ni, or an alloy including at least one of the above, can be used as the material of the solenoid.

[0098] Battery 210 can supply power to aerosol generating device 200. Battery 210 can supply power to coil 231. Battery 210 can generate direct current (DC) and may include a converter that converts the supplied DC power into alternating current (AC) to supply AC power to coil 231.

[0099] Additionally, battery 210 can supply direct current to aerosol generating device 200. Battery 210 may include, but is not limited to, lithium iron phosphate (LiFePO4) batteries. For example, batteries may include lithium cobalt oxide (LiCoO2) batteries, lithium titanate batteries, lithium polymer (LiPoly) batteries, etc.

[0100] The converter may include a low-pass filter that filters the DC current and outputs an AC current supplied to coil 231. The converter may also include an amplifier for amplifying the DC current. For example, the converter may be implemented as a low-pass filter included in the load network of a Class D amplifier.

[0101] The controller 220 can control the power supplied to the coil 231. The controller 220 can control the battery 210 to regulate the power supplied to the coil 231. For example, the controller 220 can maintain the heating temperature of the aerosol-generating article based on the temperature of the heater 230.

[0102] Figure 4 This is a block diagram of the components of an aerosol generating apparatus according to an embodiment.

[0103] Reference Figure 4 The aerosol generating device 200 may include a battery 210, a heater 230, a sensor 240, a user interface 250, a memory 260, and a controller 220. However, the internal structure of the aerosol generating device 200 is not limited to... Figure 3 The structure shown is illustrated. Based on the design of the aerosol generating apparatus 200, those skilled in the art will understand that [the following can be omitted]. Figure 3 Some of the components shown may be additional components that can be added.

[0104] Battery 210 supplies the power used by aerosol generating device 200 for operation. In other words, battery 210 can supply power so that heater 230 can be heated. Furthermore, battery 210 can supply the power required to operate other components included in aerosol generating device 200, such as sensor 240, user interface 250, memory 260, and controller 220. Battery 210 can be a rechargeable battery or a disposable battery.

[0105] The aerosol generating apparatus 200 may include at least one sensor 240. The results sensed by the at least one sensor 240 are transmitted to a controller 220, and the controller 220 may control the aerosol generating apparatus 200 to perform various functions based on the sensing results, such as controlling the operation of the heater, restricting smoking, detecting the insertion of aerosol-generated articles, and displaying notifications.

[0106] For example, at least one sensor 240 may include a suction sensor. The suction sensor may detect the user's suction based on any one of temperature changes, airflow changes, voltage changes, and air pressure changes.

[0107] Furthermore, at least one sensor 240 may include a temperature sensor for measuring the temperature of the heater 230 (or aerosol generating article). The aerosol generating apparatus 200 may include a temperature sensor configured to measure the temperature of the heater 230. Alternatively, the aerosol generating apparatus 200 may not include an additional temperature sensor, and alternatively, the heater 230 may also serve as a temperature sensor. In embodiments, in addition to the heater 230, which can function as a temperature sensor, the aerosol generating apparatus 200 may also include another temperature sensor.

[0108] At least one sensor 240 may include a temperature sensor for measuring the ambient temperature of the aerosol generating apparatus 200. The ambient temperature is the temperature outside the aerosol generating apparatus 200. The ambient temperature may be the temperature of the air into which aerosols generated from the aerosol generating article in the aerosol generating apparatus 200 are released. The temperature sensor may be disposed outside the housing to measure the ambient temperature, or it may be disposed in the path in which outside air is introduced into the aerosol generating apparatus 200. The temperature sensor may transmit information about the measured ambient temperature to a controller 220, and the controller 220 may determine a heating profile for heating the aerosol generating article based on the ambient temperature.

[0109] In addition, at least one sensor may include a humidity sensor. The humidity sensor can measure the ambient humidity of the aerosol generating apparatus 200. The ambient humidity can be the humidity outside the aerosol generating apparatus 200. The ambient humidity can be the humidity of the air into which aerosols generated from the aerosol generating article in the aerosol generating apparatus 200 are released. The humidity sensor can be arranged outside the housing to measure the ambient humidity, or it can be arranged in the path where the external air is introduced. The humidity sensor can transmit information about the measured ambient humidity to the controller 220, and the controller 220 can determine a heating profile for heating the aerosol generating article based on the ambient humidity.

[0110] Furthermore, at least one sensor may include an inductive sensor. The inductive sensor can sense whether the aerosol generating article is inserted into the aerosol generating apparatus 200. For example, the aerosol generating article may include a metallic material such as aluminum (Al), and the inductive sensor can sense the change in inductance caused by the insertion of the aerosol generating article into the aerosol generating apparatus 200. However, this is not a limitation, and the inductive sensor may be replaced by other types of sensors such as light sensors, temperature sensors, resistance sensors, etc.

[0111] When the insertion of the aerosol generating article is sensed, the controller 220 can control the aerosol generating device 200 to automatically start heating without additional external input. For example, when the insertion of the aerosol generating article is sensed, the controller 220 can control the battery 210 to supply power to the coil. However, it is not limited to this, and the controller 220 can control the aerosol generating device 200 to start heating only when additional external input is present.

[0112] User interface 250 can provide users with information about the status of aerosol generating device 200. User interface 250 may include various interface devices, such as a display or light for outputting visual information, a motor for outputting tactile information, a speaker for outputting sound information, an input / output (I / O) interface device (e.g., a button or touch screen) for receiving or outputting information from or to the user, a terminal for performing data communication or receiving charging power, and a communication interface device for wireless communication with external devices (e.g., Wi-Fi, Wi-Fi Direct, Bluetooth, Near Field Communication (NFC), etc.).

[0113] However, the aerosol generating device 200 can be implemented by selecting only some of the various interface devices 250 described above.

[0114] The user interface 250 may include a display configured to output visual information related to the aerosol generating device 200. Here, the visual information related to the aerosol generating device 200 includes all types of information related to the operation of the aerosol generating device 200. For example, the display can output information about the status of the aerosol generating device 200 (e.g., whether the aerosol generating device is available for use), information about the heater 230 (e.g., preheating started, preheating in progress, preheating completed), information about the battery 210 (e.g., remaining capacity of the battery 210, operability of the battery 210), information about the reset operation of the aerosol generating device 200 (e.g., reset cycle, reset process, reset completed), information about the cleaning of the aerosol generating device 200 (e.g., cleaning cycle, whether cleaning is required, cleaning in progress, cleaning completed), information about the charging of the aerosol generating device 200 (e.g., whether charging is required, charging in progress, charging completed), information about the suction operation (e.g., number of suctions, notification of completion of suction operation), and information about safety (e.g., expiration date).

[0115] The communication interface can connect and communicate with external devices, external servers, etc. For example, the communication interface can be implemented to support at least one of the following communication methods: various types of digital interfaces, AP-based WiFi (Wireless Local Area Network (LAN)), Bluetooth, Zigbee, wired / wireless LAN, WAN, Ethernet, IEEE 1394, HDMI, USB, MHL, AES / EBU, optical communication, and coaxial communication. Furthermore, the communication interface may include: a Transmission Minimized Differential Signaling (TMDS) channel for transmitting video and audio signals, a Display Data Channel (DDC) for transmitting and receiving device information, video or audio-related information (e.g., Enhanced Extended Display Identification Data (E-EDID)), and a Consumer Electronics Control (CEC) channel for transmitting and receiving control signals. However, it is not limited to these, and various interfaces can be implemented.

[0116] The memory 260 may be a hardware component configured to store various data processed in the aerosol generating apparatus 200, and may store data processed or to be processed by the controller 220. The memory 260 may include various types of memory, such as: random access memory, such as dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), etc.

[0117] The memory 260 can store data such as the operating time of the aerosol generating device 200, the maximum number of suction operations, the current number of suction operations, at least one temperature profile, and the user's smoking pattern.

[0118] The controller 220 typically controls the operation of the aerosol generating device 200. The controller 220 may include at least one processor. The processor may be implemented as an array of logic gates, or as a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. Those skilled in the art will understand that the processor may be implemented in other forms of hardware.

[0119] Despite Figure 4 Not shown, but the aerosol generating device 200 can be included in the aerosol generating system along with an additional bracket. For example, the bracket can be used to charge the battery 210 of the aerosol generating device 200. For example, the aerosol generating device 200 can be supplied with power from the battery in the bracket, and the battery 210 of the aerosol generating device 200 can be charged, while the aerosol generating device 200 is housed in the receiving space of the bracket.

[0120] Figure 5 yes Figure 3The diagram shows the aerosol generating apparatus. Figure 1 The aerosol-generating article shown is inserted into the aerosol-generating device.

[0121] Reference Figure 5 The aerosol generating apparatus 200 may include a housing space for housing the aerosol generating article 100, a heater 230 for heating the aerosol generating article 100, and a battery 210 for supplying power to the heater 230.

[0122] The heater 230 of the aerosol generating apparatus 200 can heat the first portion 110 of the aerosol generating article 100, and the aerosol generating element of the first portion 110 can generate aerosol. The generated aerosol can pass through the second portion 120, be cooled by a cooling element, and then be introduced into the third portion 130. The aerosol introduced into the third portion 130 can heat the tobacco element and vaporize nicotine, so that the vaporized nicotine can be transferred together with the aerosol to the fourth portion 140. The aerosol and nicotine passing through the filter element of the fourth portion 140 can be provided to the user.

[0123] The aerosol-generating article 100 can be housed in the housing space of the aerosol-generating apparatus 200 and can be heated by a heater 230 arranged to surround the housing space and at least a portion of the first portion 110. That is, the first portion 110 of the aerosol-generating article 100 can be directly heated by the heater 230 of the aerosol-generating apparatus 200, while the third portion 130 can be indirectly heated by the aerosol.

[0124] According to existing aerosol-generating articles, in order to ensure uniform aerosol and nicotine inhalation throughout the smoking time, the aerosol-generating element and the tobacco element need to be heated at different temperatures. However, since the aerosol-generating element and the tobacco element are arranged adjacent to each other, it is difficult to adjust the heating temperature differently.

[0125] In contrast, in the aerosol generating article 100 according to the embodiment, the first portion 110 and the third portion 130 are separate from each other, and therefore the temperatures of the first portion 110 and the third portion 130 can be easily adjusted differently. Furthermore, the heater 230 of the aerosol generating apparatus 200 can be arranged at a position corresponding to the first portion 110 of the aerosol generating article 100 to surround the first portion 110, such that only the first portion 110 is directly heated by the heater 230. The tobacco element included in the third portion 130 can be heated by the aerosol generated in the first portion 110 and passing through the higher temperature of the third portion 130.

[0126] Those skilled in the art will understand that various changes in form and detail can be made therein without departing from the scope of the above-described features. Therefore, the disclosed method should be considered from a descriptive rather than a limiting perspective. The scope of this disclosure is defined by the appended claims rather than by the foregoing description, and all differences within their equivalents should be understood to be included in this disclosure.
