[0023] The input / output interface 12 can transmit data corresponding to commands input by the user via the input device to other components (etc.) of the aerosol generator 10. The input / output interface 12 can output information corresponding to data received from other components (etc.) of the aerosol generator 10 via the output device.

[0024] The aerosol generation module 13 can generate an aerosol from an aerosol-generating substance. Here, the aerosol-generating substance may be one or more substances in any of the various states that can generate aerosols, such as liquid, solid, or gel states, or a combination of two or more substances.

[0025] In one embodiment, the liquid aerosol-generating substance may be a liquid containing a tobacco-containing substance that includes volatile tobacco flavor components. In other embodiments, the liquid aerosol-generating substance may be a liquid containing a non-tobacco substance. For example, the liquid aerosol-generating substance may include water, solvent, nicotine, plant extracts, fragrances, flavorings, vitamin mixtures, and the like.

[0026] Solid aerosol-generating substances can include solid materials based on tobacco raw materials such as reconstituted tobacco sheets, shredded tobacco, and tobacco granules. They can also include solid materials containing flavor modifiers, seasonings, etc. For example, flavor modifiers can include calcium carbonate, sodium bicarbonate, calcium oxide, etc. Seasonings can include natural substances such as herbal granules, silica containing aromatic compounds, zeolite, dextrin, etc.

[0027] Furthermore, the aerosol-generating substance may further contain aerosol-forming agents such as glycerin and propylene glycol.

[0028] The aerosol generation module 13 may include at least one heater.

[0029] The aerosol generation module 13 may include an electrical resistance heater. For example, the electrical resistance heater may include at least one electrical conductive track, which can be heated by an electric current flowing through the electrical conductive track. Here, the aerosol-generating material can be heated by the heated electrical resistance heater.

[0030] Electrically conductive tracks may include electrically resistant materials. For example, an electrically conductive track may be formed from a metallic material. Another example is that an electrically conductive track may be formed from a ceramic material, carbon, a metal alloy, or a composite material of a ceramic material and a metal. .

[0031] Electrical resistance heaters can include electrically conductive tracks formed in various shapes. For example, the electrically conductive tracks can be formed in any one of the following shapes: tubular, plate-shaped, needle-shaped, rod-shaped, or coil-shaped.

[0032] The aerosol generation module 13 may include a heater using induction heating. For example, an induction heating heater may include an electrically conductive coil, and by adjusting the current flowing through the electrically conductive coil, an alternating magnetic field with periodically changing direction can be generated. When an alternating magnetic field is applied to a magnetic material, energy loss may occur in the magnetic material due to eddy current loss and hysteresis loss, and the lost energy is released as thermal energy, which can heat the aerosol-generating material adjacent to the magnetic material. Here, the object that generates heat due to the magnetic field can be called a susceptor.

[0033] On the other hand, the aerosol generation module 13 can also generate aerosols from aerosol-generating materials by generating ultrasonic vibrations.

[0034] The aerosol generation module 13 can be described as a cartomizer, atomizer, or vaporizer.

[0035] The memory 14 can store programs for each signal processing and control within the control unit 17, and can also store data processed by the control unit 17 and data to be processed.

[0036] For example, the memory 14 stores application programs designed for the purpose of performing various tasks that can be processed by the control unit 17, and can selectively provide some of the stored application programs when requested by the control unit 17.

[0037] For example, memory 14 can store the operating time of the aerosol generator 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 about the user's inhalation pattern, and data about charging and discharging. Here, "puff" can mean the user's inhalation, which may be a situation in which the user draws something into their oral cavity, nasal cavity, or lungs through their mouth or nose.

[0038] The memory 14 may include at least one of the following: volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) or non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).

[0039] The sensor module 15 may include at least one sensor.

[0040] For example, the sensor module 15 may include a sensor that detects puffs (hereinafter referred to as the "puff sensor"). Here, the puff sensor can be embodied by proximity sensors such as IR sensors, pressure sensors, gyroscopes, accelerometers, magnetic field sensors, and the like.

[0041] For example, the sensor module 15 may include a sensor that detects puffs (hereinafter referred to as the "puff sensor"). Here, the puff sensor may include a pressure sensor, a gyroscope sensor, etc. This can be realized through sensors such as sirens, acceleration sensors, and magnetic field sensors.

[0042] For example, the sensor module 15 may include a sensor (hereinafter referred to as a "temperature sensor") that senses 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 can also serve as the temperature sensor. For example, the electrical resistive material of the heater may be a material that has a temperature coefficient of resistance. The sensor module 15 can sense the temperature of the heater by measuring the resistance of the heater, which changes with temperature.

[0043] For example, if a stick can be inserted into the main body of the aerosol generator 10, the sensor module 15 may include a sensor that detects the insertion of the stick (hereinafter referred to as the "stick detection sensor").

[0044] For example, if the aerosol generator 10 includes a cartridge, the sensor module 15 may include a sensor (hereinafter referred to as the "cartridge sensing sensor") that senses the attachment / detachment of the cartridge to / from the main unit, its position, etc.

[0045] Here, the stick sensing sensor and / or cartridge sensing sensor can be implemented by an inductance substrate sensor, a capacitive sensor, a resistive sensor, a Hall sensor (Hall IC) using the Hall effect, and the like.

[0046] For example, the sensor module 15 may include a voltage sensor that senses the voltage applied to a component (e.g., a battery 16) provided in the aerosol generator 10, and / or a current sensor that senses the current.

[0047] The battery 16 can supply power used to operate the aerosol generator 10 under the control of the control unit 17. The battery 16 can also supply power to other components of the aerosol generator 10. For example, the battery 16 can supply power to the communication module included in the communication interface 11, the output device included in the input / output interface 12, the heater included in the aerosol generation module 13, and so on.

[0048] Battery 16 may be a rechargeable battery or a disposable battery. For example, battery 16 may be, but is not limited to, a lithium-ion battery or a lithium polymer (Li-Polymer) battery. For example, if battery 16 is rechargeable, its charge rate (C-rate) may be 10C and its discharge rate (C-rate) may be 10C to 20C, but is not limited to these. Furthermore, for stable use, battery 16 may be manufactured to ensure that more than 80% of its total capacity is maintained even after 2000 charge-discharge cycles.

[0049] The aerosol generator 10 may further include a protection circuit module (PCM), which is a circuit for protecting the battery 16. The protection circuit module (PCM) may be positioned adjacent to the top surface of the battery 16. For example, the protection circuit module (PCM) can interrupt the circuit to the battery 16 in cases such as when a short circuit occurs in a circuit connected to the battery 16, when an overvoltage is applied to the battery 16, or when an overcurrent flows through the battery 16, in order to prevent overcharging and over-discharging of the battery 16.

[0050] The aerosol generator 10 further includes a charging terminal into which power supplied from an external source is input. For example, a charging terminal may be formed on one side of the main body of the aerosol generator 10, and the aerosol generator 10 may charge the battery 16 using power supplied through the charging terminal. Here, the charging terminal may consist of a wired terminal for USB communication, a pogo pin, or the like.

[0051] The aerosol generator 10 may further include a power terminal (not shown) into which power supplied from an external source is input. For example, a power line may be connected to a power terminal located on one side of the main body of the aerosol generator 100. The aerosol generator 10 can charge a battery using the power supplied via the power line connected to the power terminal. Here, the power terminal may be a wired terminal for USB communication.

[0052] The aerosol generator 10 can also wirelessly receive power supplied from an external source via the communication interface 11. For example, the aerosol generator 10 can receive power wirelessly using an antenna included in the communication module for wireless communication, and can charge the battery 16 using the wirelessly supplied power.

[0053] The control unit 17 can control the overall operation of the aerosol generator 10. The control unit 17 is connected to each component of the aerosol generator 10 and can transmit and / or receive signals to and from each component to control the overall operation of each component.

[0054] The control unit 17 may include at least one processor, which can be used to control the overall operation of the aerosol generator 10. Here, the processor may be a general-purpose processor such as a CPU (central processing unit). Of course, the processor may be a dedicated device such as an ASIC or a processor on another hardware base.

[0055] The control unit 17 can perform any one of several functions of the aerosol generator 10. For example, the control unit 17 can execute any one of several functions of the aerosol generator 10 (e.g., preheating function, heating function, charging function, cleaning function, etc.) depending on the state of each component of the aerosol generator 10, user commands received via the input / output interface 12, etc.

[0056] The control unit 17 can control the operation of each component of the aerosol generator 10 based on data stored in the memory 14. For example, based on data such as temperature profiles and user inhalation patterns stored in the memory 14, the control unit 17 can control the supply of a predetermined amount of power from the battery 16 to the aerosol generation module 13 for a predetermined time.

[0057] The control unit 17 can determine the occurrence of puffs via the puff sensor included in the sensor module 15. For example, the control unit 17 can check temperature changes, flow rate changes, pressure changes, voltage changes, etc., within the aerosol generator 10 based on the sensing values ​​of the puff sensor, and can determine the occurrence of puffs based on the results of the checks using the sensing values ​​of the puff sensor.

[0058] The control unit 17 can control the operation of each component of the aerosol generator 10 depending on whether or not puffing is performed and / or the number of puffs. For example, the control unit 17 can control whether the heater temperature is changed or maintained based on the temperature profile stored in the memory 14.

[0059] The control unit 17 controls the power supply to the heater to shut off under predetermined conditions. For example, the control unit 17 can control the power supply to the heater to shut off when the stick is removed and the cartridge is separated, when the number of puffs reaches the previously set maximum number of puffs, when no puffs are detected for longer than a previously set time, or when the remaining charge of the battery 16 falls below a predetermined value.

[0060] The control unit 17 can calculate the remaining amount of power stored in the battery 16 (hereinafter referred to as "remaining amount"). For example, the control unit 17 can calculate the remaining amount of battery 16 based on the sensing values ​​of the voltage sensor and / or current sensor included in the sensor module 15.

[0061] The control unit 17 can control the supply of power to the heater using at least one of the following methods: pulse width modulation (PWM) and proportional-integral-differential (PID).

[0062] For example, the control unit 17 can use a PWM method to control the supply of current pulses having a predetermined frequency and duty cycle to the heater. Here, the control unit 17 can control the power supplied to the heater by adjusting the frequency and duty cycle of the current pulses.

[0063] For example, the control unit 17 can determine a target temperature for control 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 that uses the difference between the heater temperature and the target temperature, the value obtained by integrating the difference over time, and the value obtained by differentiating the difference over time.

[0064] On the other hand, while PWM and PID methods were described as examples of control methods for supplying power to the heater, the present invention is not limited to these, and various control methods such as proportional-integral (PI) and proportional-differential (PD) methods can be used.

[0065] On the other hand, the control unit 17 can control the heater to supply power under pre-set conditions. For example, if a cleaning function is selected to clean the space in which the stick is inserted according to a command input by the user via the input / output interface 12, the control unit 17 can control the heater to supply a predetermined amount of power.

[0066] Figures 2 to 4 illustrate an aerosol generating apparatus according to an embodiment of the present disclosure.

[0067] According to various embodiments of the present invention, the aerosol generating device 10 may include a main body 100 and / or a cartridge 200.

[0068] Referring to Figure 2, the aerosol generating device 10 according to one embodiment may include a main body 100 configured so that a stick 20 can be inserted into the space formed by the housing 101.

[0069] The stick 20 may be similar to a typical combustible cigarette. For example, the stick 20 may be divided into a first part containing an aerosol-generating substance and a second part containing a filter or the like. Alternatively, the second part of the stick 20 may also contain an aerosol-generating substance. For example, an aerosol-generating substance formed in the form of granules or capsules may be inserted into the second part.

[0070] The entire first part can be inserted into the aerosol generator 10, while the second part can be exposed to the outside. Alternatively, only a portion of the first part can be inserted into the aerosol generator 10, or both the first and second parts can be inserted. The user can inhale the aerosol while holding the second part in their mouth. Here, the aerosol is generated when outside air passes through the first part, and the generated aerosol can pass through the second part and be transmitted to the user's mouth.

[0071] The main body 100 may be formed to have a structure that allows external air to flow into the main body 100 when the stick 20 is inserted. Here, the external air that flows into the main body 100 can pass through the stick 20 and flow into the user's mouth.

[0072] The heater may be positioned within the body 100 at a location corresponding to the position of the stick 20 when the stick 20 is inserted into the body 100. In this drawing, the heater is shown as an electrically conductive heater 110 including needle-shaped electrically conductive tracks, but the present invention is not limited thereto.

[0073] The heater can heat the inside and / or outside of the stick 20 using power supplied from the battery 16. Here, an aerosol can be generated in the heated stick 20. Here, the user can inhale the tobacco-flavored aerosol by inhaling through one end of the stick 20 with their mouth.

[0074] On the other hand, the control unit 17 can also control the heater to supply power even when the stick 20 is not inserted, under pre-set conditions. For example, if a cleaning function is selected to clean the space where the stick 20 is inserted, according to a command input by the user via the input / output interface 12, the control unit 17 can control the heater to supply a predetermined amount of power.

[0075] The control unit 17 can monitor the number of puffs based on the sensing value of the puff sensor from the moment the stick 20 is inserted.

[0076] The control unit 17 can initialize the current puff count stored in the memory 14 when the inserted stick 20 is removed.

[0077] Referring to Figure 3, an aerosol generating device 100 according to one embodiment may include a main body 100 that supports a cartridge 200 and a cartridge 200 that stores aerosol generating material.

[0078] In one embodiment, the cartridge 200 may be configured to be detachably attached to the main body 100. In 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 the internal space formed by the housing 101 of the main body 100.

[0079] The main unit 100 may be constructed in such a way that external air can flow into the main unit 100 when the cartridge 200 is inserted. Here, the external air that flows into the main unit 100 can flow to the user's mouth through the cartridge 200.

[0080] The control unit 17 can determine whether the cartridge 200 is being attached or detached based on the cartridge sensing sensor included in the sensor module 15. For example, cartridge sensing The sensor can transmit a pulsed current via one terminal connected to the cartridge 200. Here, the cartridge sensing sensor can detect whether the cartridge 200 is connected or not based on whether it receives a pulsed current via the other terminal.

[0081] The cartridge 200 may include a heater 210 for heating an aerosol-generating substance and / or a storage section 220 for storing the aerosol-generating substance. For example, a liquid transfer means impregnated (containing) the aerosol-generating substance may be located inside the storage section 220. The electrically conductive track of the heater 210 may be formed in a structure that winds around the liquid transfer means. Here, an aerosol can be generated by heating the liquid transfer means with the heater 210. Here, the liquid transfer means may include a wick made of cotton fibers, ceramic fibers, glass fibers, or porous ceramic.

[0082] The cartridge 200 may include an insertion space 230 into which a stick 20 can be inserted. 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 the inner side of the inner wall being open at the top and bottom. The stick 20 can be inserted into the insertion space 230 formed by the inner wall.

[0083] The insertion space into which the stick 20 is inserted may be formed in a shape corresponding to a part of the shape of the stick 20 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.

[0084] When the stick 20 is inserted into the insertion space, the outer surface of the stick 20 is surrounded by the inner wall and may come into contact with the inner wall.

[0085] A portion of the stick 20 is inserted into the insertion space 230 of the cartridge 200, while the remaining portion can be exposed to the outside.

[0086] The user can inhale the aerosol by holding one end of the stick 20 in their mouth. The aerosol generated by the heater 210 can pass through the stick 20 and be delivered to the user's mouth. As the aerosol passes through the stick 20, substances contained in the stick 20 are added to the aerosol, and the aerosol with the added substances can be inhaled into the user's oral cavity through one end of the stick 20.

[0087] Referring to Figure 4, an aerosol generating device 100 according to one embodiment may include a main body 100 that supports a cartridge 200, and a cartridge 200 that stores an aerosol generating substance. The main body 100 may be configured so that a stick 20 can be inserted into an insertion space 130.

[0088] The aerosol generator 100 may include a first heater for heating the aerosol-generating substance stored in the cartridge 200. For example, when a user inhales through one end of the stick 20, the aerosol generated by the first heater can pass through the stick 20. As the aerosol passes through the stick 20, flavoring may be added to it. The flavored aerosol can then be inhaled into the user's mouth through one end of the stick 20.

[0089] On the other hand, in other embodiments, the aerosol generator 100 may also include a first heater for heating the aerosol-generating material stored in the cartridge 200, and a second heater for heating the stick 20 inserted into the main body 100. For example, the aerosol generator 100 may heat the air stored in the cartridge 200 by the first heater and the second heater. Aerosols can also be generated by heating the aerosol-generating substance and the stick 20 separately.

[0090] Figures 5 and 6 illustrate a stick according to an embodiment of the present disclosure.

[0091] Referring to Figure 5, the stick 20 according to one embodiment may include a tobacco rod 21 and a filter rod 22. Referring to Figure 2, the first part described above may include the tobacco rod 21. Referring to Figure 2, the second part described above may include the filter rod 22.

[0092] Figure 5 shows the filter rod 22 as a single segment, but is not limited to this. In other words, the filter rod 22 may consist of multiple segments. For example, the filter rod 22 may include a first segment for cooling the aerosol and a second segment for filtering out predetermined components contained in the aerosol. Furthermore, the filter rod 22 may optionally include at least one additional segment that performs other functions.

[0093] The diameter of the stick 20 is in the range of 5mm to 9mm, and its length may be, but is not limited to, approximately 48mm. For example, the length of the tobacco rod 21 may be, but is not limited to, approximately 12mm, the length of the first segment of the filter rod 22 may be, approximately 10mm, the length of the second segment of the filter rod 22 may be, approximately 14mm, and the length of the third segment of the filter rod 22 may be, but is not limited to, approximately 12mm.

[0094] The stick 20 may be wrapped by at least one wrapper 24. The wrapper 24 may have at least one hole formed therein, through which external air enters or internal gases exit. As an example, the stick 20 may be wrapped by one wrapper 24. As another example, the stick 20 may be wrapped in layers by two or more wrappers 24. For example, the tobacco rod 21 may be wrapped by a first wrapper 241. For example, the filter rod 22 may be wrapped by wrappers 242, 243, and 244. The tobacco rod 21 and filter rod 22 wrapped by individual wrappers may be joined together, and the entire stick 20 may be further wrapped by a third wrapper. If each of the filter rods 22 consists of multiple segments, each segment may be wrapped by individual wrappers 242, 243, and 244. The entire stick 20, with the segments wrapped by individual wrappers joined together, may be further wrapped by other wrappers.

[0095] The first wrapper 241 and the second wrapper 242 can be made from general filter packaging paper. For example, the first wrapper 241 and the second wrapper 242 may be porous packaging paper or non-porous packaging paper. Alternatively, the first wrapper 241 and the second wrapper 242 may be made from oil-resistant paper and / or aluminum laminate packaging material.

[0096] The third wrapper 243 can be made from 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. Also, 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.

[0097] The fourth wrapper 244 can be made from oil-resistant hard packaging 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. Also, the thickness of the fourth wrapper 244 may be in the range of 120 μm to 130 μm. For example, the fourth wrapper 244 The thickness can be 125 μm.

[0098] The fifth wrapper 245 can be made from sterile paper (MFW). Here, sterile paper (MFW) may be a specially manufactured paper that has improved tensile strength, water resistance, smoothness, etc., compared to ordinary 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. Also, 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.

[0099] The fifth wrapper 245 may contain a predetermined substance. Here, an example of the predetermined substance may be silicon, but is not limited to silicon. For example, silicon may have properties such as heat resistance with little change due to temperature, oxidation resistance without oxidation, resistance to various chemicals, water repellency, or electrical insulation. However, any substance having the above-mentioned properties can be applied or coated to the fifth wrapper 245 without limitation, even if it is not silicon.

[0100] 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 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 cases, the fifth wrapper 245 contains a non-combustible material, so it can prevent the stick 20 from burning.

[0101] Furthermore, the fifth wrapper 245 can prevent the main body 100 from being contaminated by substances generated in the stick 20. Liquid substances may be generated in the stick 20 by the user's puffing. For example, liquid substances (e.g., water) may be generated when the aerosol generated in the stick 20 is cooled by the outside air. By wrapping the stick 20 with the fifth wrapper 245, liquid substances generated in the stick 20 can be prevented from leaking out of the stick 20.

[0102] The tobacco rod 21 may contain an aerosol-generating substance. For example, the aerosol-generating 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. Furthermore, a flavoring liquid such as menthol or a humectant may be added to the tobacco rod 21 by spraying it.

[0103] The tobacco rod 21 can be manufactured in various ways. For example, the tobacco rod 21 can be made from a sheet. For example, the tobacco rod 21 can be made from a strand. For example, the tobacco rod 21 can be made from finely cut pieces of tobacco sheet. For example, the tobacco rod 21 can be surrounded by a heat conductive material. For example, the heat conductive material can be a metal foil such as aluminum foil, but is not limited to this. As an example, the heat conductive material surrounding the tobacco rod 21 can evenly distribute the heat transferred to the tobacco rod 21, improving the heat conductivity to the tobacco rod. Thus, the tobacco flavor can be improved. The heat conductive material surrounding the tobacco rod 21 can function as a susceptor heated by an induction heater. Here, although not shown in the drawings, the tobacco rod 21 may further include additional susceptors in addition to the heat conductive material surrounding the outside.

[0104] The filter rod 22 may be a cellulose acetate filter. On the other hand, there are no restrictions on the shape of the filter rod 22. For example, the filter rod 22 may be a cylindrical (type) rod. For example, the filter rod 22 may be a tubular (type) rod with a hollow interior. For example, the filter rod 22 may be a recessed (type) rod. If the filter rod 22 is composed of multiple segments, at least one of the multiple segments may be manufactured in a different shape.

[0105] The first segment of the filter rod 22 may be a cellulose acetate filter. For example, the first segment may be a tubular structure containing a hollow interior. The first segment can prevent the internal material of the tobacco rod 21 from being pushed backward when the heater 110 is inserted, and can also provide a cooling effect for the aerosol. The diameter of the hollow interior of the first segment can be within the range of 2 mm to 4.5 mm, but is not limited to this.

[0106] The length of the first segment can be set to an appropriate length within the range of 4 mm to 30 mm, but is not limited to this. For example, the length of the first segment could be 10 mm, but is not limited to this.

[0107] The second segment of the filter rod 22 cools the aerosol generated when the heater 110 heats the tobacco rod 21. Thus, the user can inhale the aerosol cooled to a suitable temperature.

[0108] The length or diameter of the second segment can be determined in various ways depending on the form of the stick 20. For example, the length of the second segment can be appropriately adopted within the range of 7 mm to 20 mm. Preferably, the length of the second segment may be about 14 mm, but is not limited to this.

[0109] The second segment can be manufactured by weaving polymer fibers. In this case, a flavoring liquid can be applied to the polymer fibers. Alternatively, the second segment can be manufactured by weaving together a separate fiber coated with a flavoring liquid and a polymer fiber. Alternatively, the second segment can be formed from a crimped polymer sheet.

[0110] For example, polymers can be made from materials 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.

[0111] Since the second segment is formed from woven polymer fibers or a crimped polymer sheet, the second segment may include one or more longitudinally extending channels, where the channels may be passages through which a gas (e.g., air or aerosol) passes.

[0112] For example, the second segment, which consists of a crimped polymer sheet, may be formed from a material having a thickness between approximately 5 μm and approximately 300 μm, for example, between approximately 10 μm and approximately 250 μm. The total surface area of ​​the second segment may be between approximately 300 mm² / mm and approximately 1000 mm² / mm. The aerosol cooling element may be formed from a material with a specific surface area between approximately 10 mm² / mg and approximately 100 mm² / mg.

[0113] On the other hand, the second segment may include a thread containing a volatile flavor component. Here, the volatile flavor component may be menthol, but is not limited to it. For example, the thread may be filled with a sufficient amount of menthol to provide 1.5 mg or more of menthol to the second segment.

[0114] The third segment of the filter rod 22 may be a cellulose acetate filter. The length of the third segment can be appropriately adopted within the 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.

[0115] The filter rod 22 may be manufactured to generate 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.

[0116] Furthermore, the filter rod 22 may include at least one capsule 23. Here, the capsule 23 may perform the function of generating flavor. The capsule 23 may also perform the function of generating aerosol. For example, the capsule 23 may have a structure in which a liquid containing a flavor is enclosed in a film. The capsule 23 may be spherical or cylindrical, but is not limited to these.

[0117] Referring to Figure 6, the stick 30 according to one embodiment may further include a front plug 33. The front plug 33 is located on one side of the tobacco rod 31 opposite the filter rod 32. The front plug 33 can prevent the tobacco rod 31 from detaching to the outside. The front plug 33 can prevent liquefied aerosol from the tobacco rod 31 from flowing into the aerosol generator 100 during smoking.

[0118] The filter rod 32 may include a first segment 321 and a second segment 322. The first segment 321 may correspond to the first segment of the filter rod 22 in Figure 5. The second segment 322 may correspond to the third segment of the filter rod 22 in Figure 5.

[0119] The diameter and overall length of stick 30 may correspond to the diameter and overall length of stick 20 in Figure 5. For example, the length of the front plug 33 may be approximately 7 mm, the length of the tobacco rod 31 may be approximately 15 mm, the length of the first segment 321 may be approximately 12 mm, and the length of the second segment 322 may be approximately 14 mm, but are not limited to these.

[0120] The stick 30 may be wrapped by at least one wrapper 35. The wrapper 35 may have at least one hole through which external air enters or internal gases exit. For example, the front plug 33 may be wrapped by a first wrapper 351, the tobacco rod 31 by a second wrapper 352, the first segment 321 by a third wrapper 353, and the second segment 322 by a fourth wrapper 354. The entire stick 30 may then be rewrapped by a fifth wrapper 355.

[0121] Furthermore, at least one perforation 36 may be formed in the fifth wrapper 355. For example, the perforation 36 may be formed in the region surrounding the tobacco rod 31, but is not limited to this. For example, the perforation 36 may serve to transfer heat generated by the heater 210 shown in Figure 3 into the interior of the tobacco rod 31.

[0122] Furthermore, the second segment 322 may include at least one capsule 34. Here, the capsule 34 may also function to generate flavor. The capsule 34 may also function to generate aerosol. For example, the capsule 34 may have a structure in which a liquid containing a flavor is enclosed in a film. The capsule 34 may, but is not limited to, a spherical or cylindrical shape.

[0123] The first wrapper 351 can be made by bonding a metal foil, such as aluminum foil, to a general filter packaging paper. For example, the total thickness of the first wrapper 351 may be in the range of 45 μm to 55 μm. For example, the total thickness of the first wrapper 351 may be 50.3 μm. Also, the thickness of the metal foil of the first wrapper 351 may be in the range of 6 μm to 7 μm. For example, the thickness of the metal foil of the first wrapper 351 may be 6.3 μm. Also, the basis weight of the first wrapper 351 may be in the range of 50 g / m2 to 55 g / m2. For example, the basis weight of the first wrapper 351 may be 53 g / m2.

[0124] The second wrapper 352 and the third wrapper 353 can be made from general filter packaging paper. For example, the second wrapper 352 and the third wrapper 353 may be porous packaging paper or non-porous packaging paper.

[0125] For example, the porosity of the second wrapper 352 may be, but is not limited to, 35,000 CU. The thickness of the second wrapper 352 may be in the range of 70 μm to 80 μm. For example, the thickness of the second wrapper 352 may be 78 μm. The basis weight of the second wrapper 352 may be in the range of 20 g / m² to 25 g / m². For example, the basis weight of the second wrapper 352 may be 23.5 g / m².

[0126] For example, the porosity of the third wrapper 353 may be, but is not limited to, 24,000 CU. The thickness of the third wrapper 353 may be in the range of 60 μm to 70 μm. For example, the thickness of the third wrapper 353 may be 68 μm. The basis weight of the third wrapper 353 may be in the range of 20 g / m² to 25 g / m². For example, the basis weight of the third wrapper 353 may be 21 g / m².

[0127] The fourth wrapper 354 can be made from PLA laminated paper. Here, the PLA laminated paper may be a triple-layered paper containing a paper layer, a PLA layer, and another paper layer. For example, the thickness of the fourth wrapper 354 may be in the range of 100 μm to 120 μm. For example, the thickness of the fourth wrapper 354 may be 110 μm. Also, the basis weight of the fourth wrapper 354 may be in the range of 80 g / m2 to 100 g / m2. For example, the basis weight of the fourth wrapper 354 may be 88 g / m2.

[0128] The fifth wrapper 355 can be made from sterile paper (MFW). Here, sterile paper (MFW) may be a specially manufactured paper that has improved tensile strength, water resistance, smoothness, etc., compared to ordinary paper. For example, the basis weight of the fifth wrapper 355 may be in the range of 57 g / m2 to 63 g / m2. For example, the basis weight of the fifth wrapper 355 may be 60 g / m2. Also, the thickness of the fifth wrapper 355 may be in the range of 64 μm to 70 μm. For example, the thickness of the fifth wrapper 355 may be 67 μm.

[0129] The fifth wrapper 355 may contain a predetermined substance. Here, an example of the predetermined substance may be silicon, but is not limited to it. For example, silicon has properties such as heat resistance with little change due to temperature, oxidation resistance that prevents oxidation, resistance to various chemicals, water repellency, or electrical insulation. However, any substance having the above-mentioned properties can be applied (or coated) to the fifth wrapper 355 without limitation, even if it is not silicon.

[0130] The front plug 33 can be made from cellulose acetate. For example, the front plug 33 can be made by adding a plasticizer (e.g., triacetin) to cellulose acetate toe. The monodenier of the filament constituting the cellulose acetate toe can be in the range of 1.0 to 10.0. For example, the monodenier of the filament constituting the cellulose acetate toe can be in the range of 4.0 to 6.0. For example, the monodenier of the filament of the front plug 33 may be 5.0. Also, the cross-section of the filament constituting the front plug 33 may be Y-shaped. The total denier of the front plug 33 may be in the range of 20,000 to 30,000. For example, the total denier of the front plug 33 may be in the range of 25,000 to 30,000. For example, the total denier of the front plug 33 may be 28,000.

[0131] Furthermore, the front plug 33 may include at least one channel, if necessary. The cross-section of the channel can be manufactured in a variety of shapes.

[0132] The tobacco rod 31 can correspond to the tobacco rod 21 described above, as shown in Figure 5. Therefore, a detailed explanation of the tobacco rod 31 will be omitted below.

[0133] The first segment 321 may be made from cellulose acetate. For example, the first segment may be a tubular structure containing a hollow interior. The first segment 321 can be made by adding a plasticizer (e.g., triacetin) to cellulose acetate. For example, the monodenier and total denier of the first segment 321 may be the same as the monodenier and total denier of the front plug 33.

[0134] The second segment 322 can be made from cellulose acetate. The mono denier of the filament constituting the second segment 322 can be in the range of 1.0 to 10.0. For example, the mono denier of the filament of the second segment 322 can be in the range of 8.0 to 10.0. For example, the mono denier of the filament of the second segment 322 may be 9.0. Also, the cross-section of the filament of the second segment 322 may be Y-shaped. The total denier of the second segment 322 can be in the range of 20,000 to 30,000. For example, the total denier of the second segment 322 may be 25,000.

[0135] Figures 7 and 8 illustrate the configuration of an aerosol generating apparatus according to one embodiment of the present disclosure.

[0136] Referring to Figure 7, the aerosol generator 10 may include a main body 100 and a heater module 700.

[0137] The heater module 700 can be detachably coupled to the main body 100. For example, the heater module 700 can be inserted into the internal space formed by the main body 100 and mounted to the main body 100.

[0138] The heater module 700 may include a heater 710 and / or a resistive element 720. In this figure, the heater 710 is shown as being formed in a coil shape, but the disclosure is not limited thereto.

[0139] The main unit 100 may include a memory 14, a battery 16, a control unit 17, a power supply circuit 120, and / or a light-emitting element 140. The main unit 100 may also include a first connector 130 that electrically contacts the heater module 700.

[0140] The first connector 130 may include a first power terminal 131 and / or a first sensing terminal 133. The first power terminal 131 can be electrically connected to a battery 16. The first sensing terminal 133 can be electrically connected to a control unit 17. The first power terminal 131 and the first sensing terminal 133 can be electrically disconnected.

[0141] The power supply circuit 120 can be electrically connected to the battery 16 and the first power terminal 131.

[0142] The power supply circuit 120 can adjust the power supplied from the battery 16 to the heater 710. For example, the power supply circuit 120 may include a field-effect transistor (FET). Here, the power supply circuit 120 can adjust the power supplied from the battery 16 to the heater 710 by adjusting the frequency and duty cycle of the current pulse input to the gate terminal of the field-effect transistor (FET).

[0143] The control unit 17 can control the power supply circuit 120. For example, the control unit 17 can turn on the field-effect transistor (FET) to supply power from the battery 16 to the heater 710. For example, the control unit 17 can turn off the field-effect transistor (FET) to cut off the power supply to the heater 710.

[0144] The resistance value of the resistor element 720 may be greater than the resistance value of the heater 710. For example, if the resistance value of the heater 710 is 0.7Ω, the resistance value of the resistor element 720 may be 3.0kΩ.

[0145] The temperature coefficient of resistance of the resistor element 720 may be smaller than that of the heater 710. For example, the resistance value of the resistor element 720 can be maintained uniformly regardless of the temperature change of the heater 710.

[0146] The heater module 700 may include a second connector 730 that makes electrical contact with the main body 100.

[0147] The second connector 730 may include a second power terminal 731 and / or a second sensing terminal 733. The second power terminal 731 may be electrically connected to the heater 731. The second sensing terminal 733 may be electrically connected to the resistive element 720. The second power terminal 731 and the second sensing terminal 733 may be electrically disconnected.

[0148] The control unit 17 can calculate the resistance value of the resistor element 720. For example, the control unit 17 can control the flow of a predetermined level of current to the first sensing terminal 133 of the first connector 130. Here, the control unit 17 can calculate the resistance value of the resistor element 720 based on the voltage applied to the first sensing terminal 133.

[0149] On the other hand, the control unit 17 may include a configuration for calculating the resistance value of the resistor element 720. For example, the configuration for calculating the resistance value of the resistor element 720 may include a configuration for supplying a predetermined level of current to the first sensing terminal 133, a configuration for applying a predetermined level of voltage to the first sensing terminal 133, a configuration for sensing the voltage applied to the first sensing terminal 133, and a configuration for sensing the current flowing through the first sensing terminal 133. According to one embodiment, the configuration for calculating the resistance value of the resistor element 720 can also be embodied as a separate configuration distinct from the control unit 17.

[0150] The control unit 17 can determine whether to attach the heater module 700 to the main unit 100 based on the calculation of the resistance value of the resistor element 720. For example, if the control unit 17 cannot calculate the resistance value of the resistor element 720, it can determine that the heater module 700 has been separated from the main unit 100.

[0151] If the control unit 17 determines that the heater module 700 has been attached to the main unit 100, it can control the power supply circuit 120 to supply power from the battery 16 to the heater 710. If the control unit 17 determines that the heater module 700 has been separated from the main unit 100, it can control the power supply circuit 120 to cut off the power supply to the heater 710.

[0152] The control unit 17 can control the light-emitting element 140 to emit light corresponding to the state of the heater 710. For example, if the control unit 17 cannot calculate the resistance value of the resistor element 720, it can emit light via the light-emitting element 140 that corresponds to the heater 710 being unusable.

[0153] Memory 14 can store data for the resistance value of the heater 710. The control unit 17 can determine the resistance value of the heater 710 based on the data for the resistance value of the heater 710 stored in memory 14.

[0154] Referring to Figure 8, the data for the resistance value of the heater 710 may include a lookup table in which multiple first resistance values ​​corresponding to the heater 710 and multiple second resistance values ​​corresponding to the resistor element 720 are mapped to each other. Here, the multiple first resistance values ​​corresponding to the heater 710 may be resistance values ​​corresponding to a reference temperature (e.g., 25°C).

[0155] The control unit 17 can search for the second resistance value calculated as the resistance value of the resistor element 720 from among the multiple second resistance values ​​included in the lookup table. The control unit 17 can determine the first resistance value mapped to the searched second resistance value as the resistance value of the heater 710. For example, if the second resistance value calculated as the resistance value of the resistor element 720 is 2.0kΩ, the resistance value of the heater 710 can be determined to be 0.6Ω.

[0156] On the other hand, the control unit 17 can identify the heater module 700 based on whether a second resistance value corresponding to the calculated resistance value of the resistor element 720 is included in the lookup table. For example, if the calculated resistance value of the resistor element 720 is 2.25 kΩ and is not included in the lookup table, the control unit 17 can determine that the heater module 700 is an unauthenticated imitation.

[0157] Since the resistance of the resistor element 720 is much greater than the resistance of the heater 710, the resistance of the resistor element 720 can be accurately calculated even using a low level of current. Furthermore, regardless of temperature changes of the heater 710, the resistance of the heater 710 corresponding to a reference temperature (e.g., 25°C) can be accurately determined based on the resistance of the resistor element 720.

[0158] The control unit 17 can calculate the temperature of the heater 710 based on the determined resistance value of the heater 710. For example, the control unit 17 can calculate the temperature of the heater 710 based on the temperature coefficient of resistance (TCR) of the heater 710 and the determined resistance value of the heater 710.

[0159] Figure 9 is a flowchart showing the operation method of an aerosol generating apparatus according to one embodiment of the present disclosure. Detailed explanations of content that overlaps with what is described in Figures 7 and 8 are omitted.

[0160] Referring to Figure 9, the aerosol generator 10 can perform the operation of calculating the resistance value of the resistive element 720 of the heater module 700 in S910 operation. For example, when the power supply is turned on, the aerosol generator 10 can perform the operation of calculating the resistance value of the resistive element 720 of the heater module 700. For example, aerosol generation When the stick 20 is inserted into the main body 100, the device 10 can perform an operation to calculate the resistance value of the resistive element 720 of the heater module 700.

[0161] The aerosol generator 10 can determine in S920 operation whether it is possible to calculate the resistance value of the resistive element 720. For example, if the resistive element 720 of the heater module 700 is not electrically connected to the first sensing terminal 133, it may not be possible to calculate the resistance value of the resistive element 720.

[0162] The aerosol generator 10 can determine the resistance value of the heater 710 based on the calculation of the resistance value of the resistive element 720 in S930 operation.

[0163] The aerosol generator 10 can supply power to the heater 710 based on the determined resistance value of the heater 710 in S940 operation. The aerosol generator 10 can calculate the temperature of the heater 710 based on the determined resistance value of the heater 710.

[0164] On the other hand, if the aerosol generator 10 is in S950 operation and cannot calculate the resistance value of the resistive element 720, it can cut off the power supply to the heater 710.

[0165] The aerosol generator 10 can operate in S960 mode and emit light via the light-emitting element 140 that corresponds to the unavailability of the heater 710.

[0166] As described above, according to at least one of the embodiments of this disclosure, the resistance value of the heater can be accurately determined using a resistive element with a resistance value greater than that of the heater.

[0167] Furthermore, according to at least one of the embodiments of this disclosure, the resistance value of the heater can be determined regardless of the state of the heater.

[0168] Referring to Figures 1 to 9, an aerosol generating apparatus 10 according to one aspect of the present disclosure may include a heater 710 for heating an aerosol generating substance, a resistive element 720, a memory 14 for storing data on the resistance value of the heater 710, and a control unit 17. The control unit 17 can calculate the resistance value of the resistive element 720 and, based on the data stored in the memory 14, determine the resistance value of the heater 710 to correspond to the calculated resistance value of the resistive element 720. The resistance value of the resistive element 720 may exceed the resistance value of the heater 710.

[0169] Furthermore, according to other aspects of this disclosure, the data for the resistance value of the heater 710 may include a lookup table in which a plurality of first resistance values ​​corresponding to the heater 710 and a plurality of second resistance values ​​corresponding to the resistor element 720 are mapped to each other.

[0170] Furthermore, according to other aspects of this disclosure, the control unit 17 can determine that the heater 710 is an authenticated configuration if the calculated resistance value of the resistor element 720 is included in the data for the resistance value of the heater 710, and can determine that the heater 710 is an unauthenticated configuration if the calculated resistance value of the resistor element 720 is not included in the data for the resistance value of the heater 710.

[0171] Furthermore, according to other aspects of this disclosure, the aerosol generating device may further include a battery 16 and a power supply circuit 120 that adjusts the power output from the battery 16. The control unit 17, if it can calculate the resistance value of the resistive element 720, The power supply circuit 120 can be controlled so that power is supplied from the battery 16 to the heater 710. If the resistance value of the resistor element 720 cannot be calculated, the power supply circuit 120 can be controlled to cut off the power supply to the heater 710.

[0172] Furthermore, according to other aspects of this disclosure, the aerosol generating apparatus may include a main body 100 on which the memory 14 is located, and a heater module 700 on which the heater 710 and the resistive element 720 are located. The heater module 700 can be detachably mounted on the main body 100.

[0173] Furthermore, according to another aspect of this disclosure, the control unit 17 can determine whether to attach the heater module 700 to the main body 100 based on the calculation of the resistance value of the resistor element 720.

[0174] Furthermore, according to other aspects of this disclosure, the heater module 700 may include a first terminal 731 electrically connected to the heater 710 and a second terminal 733 electrically connected to the resistive element 720. The first terminal 731 and the second terminal 733 can be electrically disconnected.

[0175] Furthermore, according to other aspects of this disclosure, the aerosol generating apparatus may further include a light-emitting element 140. If the control unit 17 cannot calculate the resistance value of the resistive element 720, it may emit light through the light-emitting element 140 corresponding to the unavailability of the heater 710.
