[0026] The communication interface 11 may include at least one communication module for communication with an external device and / or a network. For example, the communication interface 11 may include a communication module for wired communication such as a universal serial bus (USB). For example, the communication interface 11 may include a communication module for wireless communication such as wireless fidelity (WiFi), Bluetooth®, Bluetooth® Low Energy (BLE), Zigbee®, or near field communication (NFC).

[0027] The input / output interface 12 may include an input device that receives commands from a user and / or an output device that outputs information to a user. For example, the input device may include a touch panel, physical buttons, a microphone, etc. For example, the output device may include a display device that outputs visual information such as a display or a light-emitting diode (LED), an audio device that outputs auditory information such as a speaker or a buzzer, a motor that outputs tactile information such as a haptic effect, etc.

[0028] The input / output interface 12 can transmit data corresponding to commands input by a user via the input device to other components (etc.) of the aerosol generating device 10. The input / output interface 12 can output information corresponding to data received from other components (etc.) of the aerosol generating device 10 via the output device.

[0029] The aerosol-generating module 13 can generate an aerosol from an aerosol-generating material. Here, the aerosol-generating material can be any one or a combination of two or more substances in various states, such as a liquid state, a solid state, or a gel state, that can generate an aerosol.

[0030] According to one embodiment, the liquid aerosol-forming material may be a liquid containing a tobacco-containing substance, including a volatile tobacco flavor component. According to another embodiment, the liquid aerosol-forming material may be a liquid containing a non-tobacco substance. For example, the liquid aerosol-forming material may include water, solvent, nicotine, plant extracts, flavorings, flavoring agents, vitamin mixtures, etc.

[0031] The solid-state aerosol-forming material may include a solid material based on tobacco raw materials, such as reconstituted tobacco sheets, shredded tobacco, or granulated tobacco. The solid-state aerosol-forming material may also include a solid material containing a taste modifier, a flavoring, or the like. For example, the taste modifier may include calcium carbonate, sodium bicarbonate, calcium oxide, or the like. For example, the flavoring may include natural substances such as herb granules, or silica, zeolite, dextrin, or the like containing flavoring ingredients.

[0032] The aerosol generating material may further include an aerosol forming agent such as glycerin or propylene glycol.

[0033] The aerosol generation module 13 can include at least one heater.

[0034] The aerosol generation module 13 may include an electrical resistive heater. For example, the electrical resistive heater may include at least one electrically conductive track and may be heated by passing an electric current through the electrically conductive track. The heated electrical resistive heater may then heat the aerosol-generating material.

[0035] The electrically conductive tracks may comprise an electrically resistive material. As an example, the electrically conductive tracks may be made of a metal material. As another example, the electrically conductive tracks may be made of a ceramic material, carbon, a metal alloy, or a composite of a ceramic material and a metal.

[0036] The electric resistance heater may include an electrically conductive track formed in a variety of shapes, for example, the electrically conductive track may be formed in any one of a tube shape, a plate shape, a needle shape, a rod shape, and a coil shape.

[0037] The aerosol generation module 13 may include a heater that uses induction heating. For example, an induction heater may include an electrically conductive coil, and an alternating magnetic field whose direction periodically changes may be generated by adjusting the current flowing through the electrically conductive coil. When an alternating magnetic field is applied to a magnetic material, energy loss due to eddy current loss and hysteresis loss may occur in the magnetic material. The lost energy may be released as thermal energy, heating the aerosol-generating material adjacent to the magnetic material. Here, the object that generates heat due to the magnetic field may be referred to as a susceptor.

[0038] On the other hand, the aerosol generation module 13 can also generate an aerosol from the aerosol-generating substance by generating ultrasonic vibrations.

[0039] The aerosol generating module 13 may be referred to as a cartomizer, an atomizer, a vaporizer, or the like.

[0040] The memory 14 can store programs for various signal processing and control within the control unit 17, and can store data processed by the control unit 17 and data to be processed.

[0041] For example, memory 14 may store application programs designed to perform various tasks that can be processed by control unit 17, and may selectively provide some of the stored application programs upon request of control unit 17.

[0042] For example, the memory 14 may store the operating time of the aerosol generating device 10, the maximum number of puffs, the current number of puffs, the number of times the battery 16 has been charged, the number of times the battery 16 has been discharged, at least one temperature profile, data on the user's inhalation pattern, data on charging and discharging, etc. Here, a puff may refer to the user's inhalation, and inhalation may be a situation in which the user inhales through the mouth or nose into the user's oral cavity, nasal cavity, or lungs.

[0043] The memory 14 may include at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.), non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).

[0044] The sensor module 15 can include at least one sensor.

[0045] For example, the sensor module 15 may include a sensor for detecting a puff (hereinafter referred to as a puff sensor). Here, the puff sensor may be implemented by a proximity sensor such as an IR sensor, a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.

[0046] For example, the sensor module 15 may include a sensor for detecting a puff (hereinafter referred to as a puff sensor). Here, the puff sensor may be implemented by a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.

[0047] For example, the sensor module 15 may include a sensor (hereinafter referred to as a temperature sensor) that detects the temperature of the heater included in the aerosol generation module 13, the temperature of the aerosol-generating material, etc. Here, the heater included in the aerosol generation module 13 may also function as a temperature sensor. For example, the electrically resistive material of the heater may be a material having a temperature coefficient of resistance (TCR). The sensor module 15 may sense the temperature of the heater by measuring the resistance of the heater, which changes depending on the temperature.

[0048] For example, if a stick can be inserted into the main body of the aerosol generation device 10, the sensor module 15 can include a sensor that detects the insertion of the stick (hereinafter referred to as a stick detection sensor).

[0049] For example, if the aerosol generation device 10 includes a cartridge, the sensor module 15 may include a sensor (hereinafter referred to as a cartridge detection sensor) that detects the attachment / detachment, position, etc. of the cartridge relative to the main body.

[0050] Here, the stick detection sensor and / or cartridge detection sensor may be implemented by an inductance-based sensor, a capacitance-type sensor, a resistance sensor, a hall sensor (hall IC) using the hall effect, or the like.

[0051] For example, the sensor module 15 may include a voltage sensor that detects the voltage applied to a component (e.g., the battery 16) provided in the aerosol generating device 10 and / or a current sensor that detects the current.

[0052] The battery 16 can supply power used for the operation of the aerosol generation device 10 under the control of the control unit 17. The battery 16 can supply power to other components provided in the aerosol generation device 10. For example, the battery 16 can supply power to a communication module included in the communication interface 11, an output device included in the input / output interface 12, a heater included in the aerosol generation module 13, etc.

[0053] The battery 16 may be a rechargeable battery or a disposable battery. For example, the battery 16 may be, but is not limited to, a lithium-ion battery or a lithium polymer (Li-Polymer) battery. For example, if the battery 16 is rechargeable, the charge rate (C-rate) of the battery 16 may be, but is not limited to, 10C and the discharge rate (C-rate) of the battery 16 may be, but is not limited to, 10C to 20C. For stable use, the battery 16 may be manufactured to maintain 80% or more of its total capacity even after 2000 charge / discharge cycles.

[0054] The aerosol generating device 10 may further include a battery protection circuit module (PCM), which is a circuit for protecting the battery 16. The battery protection module (PCM) may be disposed adjacent to the upper surface of the battery 16. For example, to prevent overcharging and over-discharging of the battery 16, the battery protection module (PCM) may cut off the electrical path to the battery 16 when a short circuit occurs in a circuit connected to the battery 16, when an overvoltage is applied to the battery 16, when an overcurrent flows through the battery 16, or the like.

[0055] The aerosol generating device 10 may further include a charging terminal to which externally supplied power is input. For example, a charging terminal may be formed on one side of the body of the aerosol generating device 10, and the aerosol generating device 10 may charge the battery 16 using power supplied through the charging terminal. Here, the charging terminal may be a wired terminal for USB communication, a pogo pin, or the like.

[0056] The aerosol generating device 10 may further include a power terminal (not shown) to which externally supplied power is input. For example, a power line may be connected to the power terminal disposed on one side of the body of the aerosol generating device 10. The aerosol generating device 10 may charge a battery using power supplied through the power line connected to the power terminal. Here, the power terminal may be a wired terminal for USB communication.

[0057] The aerosol generation device 10 can also wirelessly receive power supplied from an external source via the communication interface 11. For example, the aerosol generation device 10 can receive power wirelessly using an antenna included in a communication module for wireless communication, and can charge the battery 16 using the wirelessly supplied power.

[0058] The control unit 17 can control the overall operation of the aerosol generation device 10. The control unit 17 is connected to each component provided in the aerosol generation device 10, and can transmit and / or receive signals between each component to control the overall operation of each component.

[0059] The control unit 17 may include at least one processor and may use the processor to control the overall operation of the aerosol generating device 10. Here, the processor may be a general processor such as a central processing unit (CPU). Of course, the processor may be a dedicated device such as an ASIC or a processor based on other hardware.

[0060] The control unit 17 can perform any one of the multiple functions of the aerosol generation device 10. For example, the control unit 17 can execute any one of the multiple functions of the aerosol generation device 10 (e.g., preheating function, heating function, charging function, cleaning function, etc.) depending on the state of each component provided in the aerosol generation device 10, a user command received via the input / output interface 12, etc.

[0061] The control unit 17 can control the operation of each component included in the aerosol generation device 10 based on the data stored in the memory 14. For example, the control unit 17 can control the battery 16 to supply a predetermined amount of power to the aerosol generation module 13 for a predetermined period of time based on data about the temperature profile, the user's inhalation pattern, etc. stored in the memory 14.

[0062] The control unit 17 can determine whether a puff has occurred through the puff sensor included in the sensor module 15. For example, the control unit 17 can check changes in temperature, flow rate, pressure, voltage, etc. within the aerosol generating device 10 based on the sensing value of the puff sensor, and can determine whether a puff has occurred based on the confirmed results based on the sensing value of the puff sensor.

[0063] The control unit 17 can control the operation of each component included in the aerosol generating device 10 depending on whether or not a puff is performed and / or the number of puffs. For example, the control unit 17 can control the heater temperature to be changed or maintained based on the temperature profile stored in the memory 14.

[0064] The control unit 17 can control the power supply to the heater to be cut off under predetermined conditions, such as when the stick is removed and the cartridge is separated, when the number of puffs reaches a preset maximum number of puffs, when no puffs are detected for a preset time, or when the remaining charge of the battery 16 is less than a predetermined value.

[0065] The control unit 17 may calculate the remaining amount of power (hereinafter referred to as the remaining amount) stored in the battery 16. For example, the control unit 17 may calculate the remaining amount of the battery 16 based on the sensing values ​​of the voltage sensor and / or the current sensor included in the sensor module 15.

[0066] The control unit 17 can control the supply of power to the heater using at least one of a pulse width modulation (PWM) method and a proportional-integral-differential (PID) method.

[0067] For example, the control unit 17 may use a PWM method to control the supply of a current pulse having a predetermined frequency and duty ratio to the heater, where the control unit 17 may control the power supplied to the heater by adjusting the frequency and duty ratio of the current pulse.

[0068] For example, the control unit 17 can determine a target temperature based on the temperature profile. Here, the control unit 17 can control the power supplied to the heater using a PID method, which is a feedback control method using a difference between the heater temperature and the target temperature, a value obtained by integrating the difference over time, and a value obtained by differentiating the difference over time.

[0069] Meanwhile, although the PWM method and the PID method have been described as examples of control methods for supplying power to the heater, the present invention is not limited thereto, and various control methods such as a Proportional-Integral (PI) method and a Proportional-Differential (PD) method can be used.

[0070] Meanwhile, the control unit 17 may control the heater to supply power under preset conditions. For example, when a cleaning function for cleaning a space where the stick is inserted is selected according to a command input by the user via the input / output interface 12, the control unit 17 may control the heater to supply a predetermined amount of power.

[0071] 2 and 3 are diagrams illustrating an aerosol generating device according to an embodiment of the present disclosure.

[0072] According to various embodiments of the present invention, the aerosol generating device 10 can include a body 100 and / or a cartridge 200 .

[0073] The stick 20 may be divided into a first portion containing an aerosol-generating substance and a second portion containing a filter or the like. Alternatively, the second portion of the stick 20 may also contain an aerosol-generating substance. For example, the aerosol-generating substance in the form of granules or capsules may be inserted into the second portion.

[0074] The entire first part may be inserted into the aerosol generation device 10, and the second part may be exposed to the outside. Alternatively, only a portion of the first part may be inserted into the aerosol generation device 10, or both the first part and the second part may be inserted. A user can inhale the aerosol by holding the second part in their mouth. Here, the aerosol is generated by external air passing through the first part, and the generated aerosol can be delivered to the user's mouth by passing through the second part.

[0075] Referring to FIG. 2, an aerosol generating device 10 according to one embodiment can include a body 100 that supports a cartridge 200, and the cartridge 200 stores an aerosol generating substance.

[0076] According to one embodiment, the cartridge 200 may be configured to be detachable from the main body 100. According to another embodiment, the cartridge 200 may be configured integrally with the main body 100. For example, the cartridge 200 may be attached to the main body 100 by inserting at least a portion of the cartridge 200 into an internal space formed by the housing 101 of the main body 100.

[0077] The main body 100 may be formed in a structure that allows external air to flow into the main body 100 when the cartridge 200 is inserted. Here, the external air that has flowed into the main body 100 may flow to the user's mouth through the cartridge 200.

[0078] The control unit 17 can determine whether the cartridge 200 is attached or detached by using a cartridge detection sensor included in the sensor module 15. For example, the cartridge detection sensor can transmit a pulse current through one terminal connected to the cartridge 200. Here, the cartridge detection sensor can detect whether the cartridge 200 is attached or detached based on whether the pulse current is received through another terminal.

[0079] The cartridge 200 may include a heater 210 for heating an aerosol-generating substance and / or a reservoir 220 for storing the aerosol-generating substance. For example, a liquid transfer means impregnated (containing) the aerosol-generating substance may be disposed inside the reservoir 220. The electrically conductive track of the heater 210 may be formed in a structure that wraps around the liquid transfer means. Here, the liquid transfer means may be heated by the heater 210 to generate an aerosol. Here, the liquid transfer means may include a wick made of cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0080] The cartridge 200 may include an insertion space 230 configured to allow the insertion of the stick 20. For example, the cartridge 200 may include an insertion space formed by an inner wall (not shown) extending circumferentially along the direction in which the stick 20 is inserted. Here, the insertion space may be formed by opening the inside of the inner wall upward and downward. The stick 20 may be inserted into the insertion space 230 formed by the inner wall.

[0081] The insertion space into which the stick 20 is inserted may be formed in a shape corresponding to the shape of a portion of the stick 20 to be inserted into the insertion space. For example, if the stick 20 is formed in a cylindrical shape, the insertion space may be formed in a cylindrical shape.

[0082] When the stick 20 is inserted into the insertion space, the outer circumferential surface of the stick 20 is surrounded by the inner wall and can come into contact with the inner wall.

[0083] A part of the stick 20 is inserted into the insertion space 230 of the cartridge 200, and the remaining part can be exposed to the outside.

[0084] A user can inhale the aerosol while holding one end of the stick 20 in their mouth. The aerosol generated by the heater 210 can be delivered to the user's mouth through the stick 20. As the aerosol passes through the stick 20, the substance contained in the stick 20 is added to the aerosol, and the aerosol with the added substance can be inhaled into the user's mouth through one end of the stick 20.

[0085] 3, an aerosol generating device 10 according to one embodiment may include a main body 100 that supports a cartridge 200, and the cartridge 200 stores an aerosol-generating substance. The main body 100 may be configured so that the stick 20 can be inserted into an insertion space 130.

[0086] The aerosol generating device 10 may include a first heater that heats the aerosol-generating material stored in the cartridge 200. For example, when a user inhales through one end of the stick 20 into the mouth, the aerosol generated by the first heater can pass through the stick 20. Here, a flavor can be added to the aerosol as it passes through the stick 20. The flavored aerosol can be inhaled into the user's mouth through one end of the stick 20.

[0087] Meanwhile, according to another embodiment, the aerosol generating device 10 may include a first heater that heats the aerosol generating material stored in the cartridge 200 and a second heater that heats the stick 20 inserted into the main body 100. For example, the aerosol generating device 10 may generate an aerosol by heating the aerosol generating material stored in the cartridge 200 and the stick 20 using the first heater and the second heater, respectively.

[0088] 4 to 6 are diagrams illustrating a stick according to an embodiment of the present disclosure.

[0089] 4, a stick 20 according to one embodiment can include a tobacco rod 21 and a filter rod 22. The first portion described above with reference to Figures 2 and 3 can include the tobacco rod 21. The second portion described above with reference to Figures 2 and 3 can include the filter rod 22.

[0090] Although the filter rod 22 is shown in Figure 5 as a single segment, this is not limiting. In other words, the filter rod 22 may be composed of multiple segments. For example, the filter rod 22 may include a first segment that cools the aerosol and a second segment that filters a specific component contained in the aerosol. If necessary, the filter rod 22 may also include at least one additional segment that performs another function.

[0091] The stick 20 may have a diameter ranging from 5 mm to 9 mm and a length of approximately 48 mm, but is not limited thereto. For example, the tobacco rod 21 may have a length of approximately 12 mm, the first segment of the filter rod 22 may have a length of approximately 10 mm, the second segment of the filter rod 22 may have a length of approximately 14 mm, and the third segment of the filter rod 22 may have a length of approximately 12 mm, but is not limited thereto.

[0092] The stick 20 may be wrapped in at least one wrapper 24. The wrapper 24 may have at least one hole formed therein, allowing external air to enter or internal gas to escape. As an example, the stick 20 may be wrapped in a single wrapper 24. As another example, the stick 20 may be wrapped in two or more overlapping wrappers 24. For example, the tobacco rod 21 may be wrapped in a first wrapper 241. For example, the filter rod 22 may be wrapped in wrappers 242, 243, and 244. The tobacco rod 21 and the filter rod 22 wrapped in individual wrappers may be combined, and the entire stick 20 may be further wrapped in a third wrapper. If each filter rod 22 is composed of multiple segments, each segment may be wrapped in an individual wrapper 242, 243, and 244. The entire stick 20, including the combined segments wrapped in individual wrappers, may be further wrapped in another wrapper.

[0093] The first wrapper 241 and the second wrapper 242 may be made of a common filter wrapper. For example, the first wrapper 241 and the second wrapper 242 may be porous or non-porous. The first wrapper 241 and the second wrapper 242 may also be made of oil-resistant paper and / or aluminum laminate packaging material.

[0094] The third wrapper 243 may be made of hard wrapping paper. For example, the basis weight of the third wrapper 243 may be in the range of 88 g / m² to 96 g / m². For example, the basis weight of the third wrapper 243 may be in the range of 90 g / m² to 94 g / m². The thickness of the third wrapper 243 may be in the range of 120 μm to 130 μm. For example, the thickness of the third wrapper 243 may be 125 μm.

[0095] The fourth wrapper 244 may be made of oil-resistant hard wrapping paper. For example, the basis weight of the fourth wrapper 244 may be in the range of 88 g / m² to 96 g / m². For example, the basis weight of the fourth wrapper 244 may be in the range of 90 g / m² to 94 g / m². The thickness of the fourth wrapper 244 may be in the range of 120 μm to 130 μm. For example, the thickness of the fourth wrapper 244 may be 125 μm.

[0096] The fifth wrapper 245 may be made of a sterilized paper (MFW). The sterilized paper (MFW) may be specially manufactured to have improved tensile strength, water resistance, smoothness, etc. compared to general paper. For example, the basis weight of the fifth wrapper 245 may be in the range of 57 g / m² to 63 g / m². For example, the basis weight of the fifth wrapper 245 may be 60 g / m². 2 The thickness of the fifth wrapper 245 may be in the range of 64 μm to 70 μm. For example, the thickness of the fifth wrapper 245 may be 67 μm.

[0097] The fifth wrapper 245 may include a predetermined material. An example of the predetermined material may be, but is not limited to, silicon. For example, silicon may have properties such as heat resistance (i.e., small changes due to temperature), oxidation resistance (i.e., no oxidation), resistance to various chemicals, water repellency, and electrical insulation. However, any material other than silicon that has the above-mentioned properties may be applied or coated onto the fifth wrapper 245 without limitation.

[0098] The fifth wrapper 245 can prevent the stick 20 from burning. For example, when the tobacco rod 21 is heated by the heater 210, the stick 20 may burn. Specifically, if the temperature of the tobacco rod 21 rises above the flash point of any one of the materials contained in the tobacco rod 21, the stick 20 may burn. Even in such a case, the fifth wrapper 245 contains a non-flammable material, so the stick 20 can be prevented from burning.

[0099] In addition, the fifth wrapper 245 can prevent the main body 100 from being contaminated by the substance produced in the stick 20. A liquid substance can be produced in the stick 20 when the user puffs. For example, a liquid substance (e.g., water) can be produced when the aerosol produced in the stick 20 is cooled by external air. The fifth wrapper 245 wraps the stick 20, thereby preventing the liquid substance produced in the stick 20 from leaking out of the stick 20.

[0100] The tobacco rod 21 may contain an aerosol-forming substance. For example, the aerosol-forming substance may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The tobacco rod 21 may also contain other additives such as flavoring agents, humectants, and / or organic acids. A flavoring liquid such as menthol or a humectant may be added to the tobacco rod 21 by spraying it onto the tobacco rod 21.

[0101] The tobacco rod 21 can be manufactured in a variety of ways. For example, the tobacco rod 21 can be manufactured from a sheet. For example, the tobacco rod 21 can be manufactured from a strand. For example, the tobacco rod 21 can be manufactured from finely chopped tobacco sheets. For example, the tobacco rod 21 can be surrounded by a thermally conductive material. For example, the thermally conductive material can be, but is not limited to, a metal foil such as aluminum foil. For example, the thermally conductive material surrounding the tobacco rod 21 can uniformly distribute heat transferred to the tobacco rod 21 and improve thermal conductivity to the tobacco rod, thereby improving the tobacco taste. The thermally conductive material surrounding the tobacco rod 21 can function as a susceptor heated by an induction heater. Although not shown in the drawings, the tobacco rod 21 can further include an additional susceptor in addition to the thermally conductive material surrounding the exterior.

[0102] The filter rod 22 may be a cellulose acetate filter. However, the shape of the filter rod 22 is not limited. For example, the filter rod 22 may be a cylindrical rod. For example, the filter rod 22 may be a tube-type rod having a hollow interior. For example, the filter rod 22 may be a recess-type rod. When the filter rod 22 is composed of multiple segments, at least one of the multiple segments may be manufactured in a different shape.

[0103] The first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tubular structure having a hollow interior. The first segment prevents the inner material of the tobacco rod 21 from being pushed backward when the heater 110 is inserted, and also provides a cooling effect for the aerosol. The diameter of the hollow interior of the first segment may be an appropriate diameter within the range of 2 mm to 4.5 mm, but is not limited thereto.

[0104] The length of the first segment can be an appropriate length within the range of 4 mm to 30 mm, but is not limited thereto. For example, the length of the first segment can be 10 mm, but is not limited thereto.

[0105] The second segment of the filter rod 22 cools the aerosol generated by the heater 110 heating the tobacco rod 21. Thus, the user can inhale the aerosol cooled to an appropriate temperature.

[0106] The length or diameter of the second segment can be determined in various ways depending on the shape of the stick 20. For example, the length of the second segment can be appropriately set within the range of 7 mm to 20 mm. Preferably, the length of the second segment can be about 14 mm, but is not limited to this.

[0107] The second segment can be made by weaving polymer fibers, in which case a flavor liquid can be applied to the polymer fibers, or by weaving the polymer fibers together with separate fibers that have been coated with a flavor liquid, or by forming the second segment from a crimped polymer sheet.

[0108] For example, the polymer may be made from a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil.

[0109] The second segment may be formed from woven polymer fibers or a crimped polymer sheet, such that the second segment includes one or more longitudinally extending channels, where the channels may be passageways through which a gas (e.g., air or aerosol) may pass.

[0110] For example, the second segment of crimped polymer sheet may be formed from a material having a thickness between about 5 μm and about 300 μm, such as between about 10 μm and about 250 μm, and the total surface area of ​​the second segment may be less than about 300 mm 2 / mm and approximately 1000mm 2 / mm. The aerosol cooling element may have a specific surface area of ​​about 10 mm 2 / mg and about 100mm 2 It can be made from materials between 1 / mg.

[0111] Meanwhile, the second segment can include a thread containing a volatile flavor component, which can be, but is not limited to, menthol. For example, the thread can be loaded with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0112] The third segment of the filter rod 22 may be a cellulose acetate filter. The length of the third segment may be appropriately selected within a range of 4 mm to 20 mm. For example, the length of the third segment may be approximately 12 mm, but is not limited to this.

[0113] The filter rod 22 may be manufactured to emit a flavor. For example, a flavoring liquid may be sprayed onto the filter rod 22. For example, a separate fiber coated with a flavoring liquid may be inserted into the filter rod 22.

[0114] The filter rod 22 may also include at least one capsule 23. The capsule 23 may function to generate a flavor. The capsule 23 may also function to generate an aerosol. For example, the capsule 23 may have a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 23 may have, but is not limited to, a spherical or cylindrical shape.

[0115] 5, the stick 30 according to one embodiment may further include a front-end plug 33. The front-end plug 33 is located on one side of the tobacco rod 31, facing the filter rod 32. The front-end plug 33 prevents the tobacco rod 31 from detaching to the outside. The front-end plug 33 prevents aerosol liquefied from the tobacco rod 31 during smoking from flowing into the aerosol generation device 10.

[0116] Filter rod 32 can include a first segment 321 and a second segment 322. First segment 321 can correspond to the first segment of filter rod 22 of Figure 5. Second segment 322 can correspond to the third segment of filter rod 22 of Figure 5.

The entire stick 30 may then be rewrapped in a fifth wrapper 355.

[0119] In addition, at least one perforation 36 may be formed in the fifth wrapper 355. For example, but not limited to, the perforation 36 may be formed in the area surrounding the tobacco rod 31.

[0133] 6, the stick 40 may include a medium portion 410. The stick 40 may include a cooling portion 420. The stick 40 may include a filter portion 430. The cooling portion 420 may be disposed between the medium portion 410 and the filter portion 430. The stick 40 may include a wrapper 440. The wrapper 440 may wrap the medium portion 410. The wrapper 440 may wrap the cooling portion 420. The wrapper 440 may wrap the filter portion 430. The stick 40 may have a cylindrical shape.

[0134] The medium portion 410 may include a medium 411. The medium portion 410 may include a first medium cover 413. The medium portion 410 may include a second medium cover 415.

The second medium cover 415 may be made of paper material. At least one of the first medium cover 413 and the second medium cover 415 may be made of paper material and may have a wrinkled shape, forming a plurality of gaps between them for air to flow. The gaps may be smaller than the size of each granule of the medium 411. The length L1 of the first medium cover 413 may be shorter than the length L2 of the medium 411. The length L3 of the second medium cover 413 may be shorter than the length L2 of the medium 411. The length L1 of the first medium cover 413 may be 7 mm.

[0144] FIG. 7 is a diagram illustrating the configuration of an aerosol generating device according to one embodiment of the present invention.

[0145] Referring to FIG. 7, the aerosol generating device 10 can include a main body 100 and a cartridge 200.

[0146] The main body 100 may include a control unit 17, a memory 140, and / or a puff sensor 150 that detects a puff.

[0147] The cartridge 200 may include a heater 210 and / or a memory 240 .

[0148] The memory 140 of the main body 100 may store data corresponding to the components included in the main body 100. For example, the memory 140 of the main body 100 may store data regarding the total capacity of the battery 16.

[0149] The memory 240 of the cartridge 200 may store data corresponding to the configuration included in the cartridge 200. For example, the memory 240 of the cartridge 200 may store data regarding the resistance of the heater 210, data regarding the temperature profile, data regarding the aerosol-generating material contained in the storage portion 220, and data regarding the predetermined number of puffs.

[0150] The main body 100 and the cartridge 200 may each include at least one connection terminal 180, 280. When the main body 100 and the cartridge 200 are coupled together, the connection terminal 180 of the main body 100 and the connection terminal 280 of the cartridge 200 may be electrically connected.

[0151] The control unit 17 of the main body 100 and the memory 240 of the cartridge 200 can communicate with each other. For example, the control unit 17 of the main body 100 and the memory 240 of the cartridge 200 can communicate with each other using a single-wire communication interface (1-wire interface) according to a predetermined protocol. Here, signals can be transmitted between the control unit 17 of the main body 100 and the memory 240 of the cartridge 200 via the connection terminals 180, 280 of the main body 100 and the cartridge 200.

[0152] The control unit 17 can acquire data from the memory 240 of the cartridge 200. For example, the control unit 17 can receive at least a portion of the data stored in the memory 240 of the cartridge 200 from the memory 240 of the cartridge 200.

[0153] The control unit 17 can check the data stored in the memory 240 of the cartridge 200. For example, the control unit 17 can check the resistance value of the heater 210 corresponding to a reference temperature and the temperature coefficient of resistance (TCR) of the heater 210 based on the data about the heater 210 among the data stored in the memory 240 of the cartridge 200. For example, the control unit 17 can check the components and composition ratio of the aerosol-generating material based on the data about the aerosol-generating material among the data stored in the memory 240 of the cartridge 200.

[0154] The control unit 17 can process the data stored in the memory 240 of the cartridge 200. For example, the control unit 17 can add new data to the data stored in the memory 240 of the cartridge 200. For example, the control unit 17 can change or delete the data stored in the memory 240 of the cartridge 200.

[0155] The control unit 17 can determine whether the data stored in the memory 240 of the cartridge 200 is valid. For example, the control unit 17 can determine whether the data about the heater 210 is valid based on whether the resistance value of the heater 210 included in the data about the heater 210 is within a predetermined resistance range. For example, the control unit 17 can determine whether the data about the heater 210 is valid based on whether the temperature coefficient of resistance (TCR) of the heater 210 included in the data about the heater 210 is within a predetermined TCR range. For example, the control unit 17 can determine whether the data about the temperature profile is valid based on whether a predetermined number of temperature profiles are stored in the data about the temperature profile. For example, the control unit 17 can determine whether the data about the temperature profile is valid based on whether a predetermined number of temperature profiles are stored in the data about the temperature profile.

[0156] According to one embodiment, the data stored in memory 240 of cartridge 200 may be encrypted data.

[0157] The control unit 17 can decrypt data stored in the memory 240 of the cartridge 200 according to a predetermined standard. For example, the control unit 17 can decrypt data stored in the memory 240 of the cartridge 200 based on an encryption key stored in the memory 140 of the main body 100. Here, when the decryption of the data stored in the memory 240 of the cartridge 200 is completed, the control unit 17 can determine that the cartridge 200 is an authenticated cartridge.

[0158] The control unit 17 can add encrypted data to the memory 240 of the cartridge 200 according to a predetermined standard. For example, the control unit 17 can transmit data about the number of times puffs are detected via the puff sensor 150, encrypted based on an encryption key stored in the memory 140 of the main body 100, to the memory 240 of the cartridge 200.

[0159] In the present disclosure, a Symmetric Key Cryptography (SKC) method is used in which the encryption key used for encryption and the encryption key used for decryption are the same, but the present disclosure is not limited thereto.
