Description

Technical Field

[0001] Various embodiments of the present invention relate to an aerosol generating apparatus that can sense the over-wetness and over-dryness of cigarettes using a humidity-sensitive resistor sensor. Background Technology

[0002] In recent years, there has been a growing demand for alternative methods to overcome the drawbacks of conventional cigarettes. For example, there is a growing need for methods that generate aerosols by heating aerosol-generating substances, rather than by burning cigarettes. Therefore, research on heated aerosol generating devices is actively underway.

[0003] When the aerosol-generating article is inserted into the containment space, the aerosol-generating device heats the article according to a preset temperature profile. The temperature profile refers to the temperature change data of the heater or the aerosol-generating article during the smoking process. The aerosol generated by heating the aerosol-generating article can vary depending on the composition of the aerosol-generating substance contained within it. For example, the temperature and yield of the generated aerosol can differ depending on the water content of the aerosol-generating substance. Summary of the Invention

[0004] The problem the invention aims to solve When an aerosol-generating article contains a certain amount of moisture, preheating the article can generate aerosols at appropriate temperatures and yields. However, when the moisture content of the aerosol-generating article exceeds a suitable range during preheating, the moisture causes a decrease in the heating rate of the heater, resulting in the generation of excessive water vapor and high-temperature aerosols. Conversely, when the moisture content of the aerosol-generating article is below a suitable range during preheating, it may be difficult to generate sufficient aerosols. Therefore, there is a need for an aerosol generating device that can be configured with different preheating temperature profiles based on the moisture content of the aerosol-generating article.

[0005] However, the problems solved by the embodiments of the present invention are not limited to the problems described above, and those skilled in the art to which the embodiments of the present invention pertain can clearly understand the problems not mentioned from this specification and the accompanying drawings.

[0007] Invention Effects According to various embodiments of the present invention, the aerosol generating apparatus can place a humidity-sensitive resistor sensor on a membrane provided with a heater, thereby enabling the sensing of the humidity of the aerosol generating article inserted in the containment section even without adding a separate component for placing the humidity-sensitive resistor sensor.

[0028] Figure 1 This is a block diagram of an aerosol generating apparatus 1 according to one embodiment.

[0029] According to one embodiment, the aerosol generating apparatus 1 may include a power supply 11, a control unit 12, a sensor unit 13, an output unit 14, an input unit 15, a communication unit 16, a memory 17, and / or heaters 18 and 24. However, those skilled in the art will understand that, according to the design of the aerosol generating apparatus 1, certain components may be omitted. Figure 1 The shown components may include some of the constituent elements, or new constituent elements may be added.

[0030] According to one embodiment, the sensor unit 13 can sense the state of the aerosol generating device 1 or the state around the aerosol generating device 1, and transmit the sensed information to the control unit 12. For example, the sensor unit 13 may include a temperature sensor, a puff sensor, an insertion sensor, a reuse sensor, an overly moist sensor, a cigarette identification sensor, a cartridge sensor, a cap sensor, and / or a motion sensor. In addition, the sensor unit 13 may also include various sensors such as a liquid level sensor for sensing the remaining liquid in the cartridge and a water immersion sensor for sensing water immersion in the aerosol generating device 1.

[0031] According to one embodiment, a temperature sensor can sense the temperature at which heaters 18 and 24 are heated. The aerosol generating apparatus 1 may include a separate temperature sensor for sensing the temperature of heaters 18 and 24, or the heaters 18 and 24 themselves may function as temperature sensors. As an example, the temperature sensor can be used to measure the impedance of heater 18. The impedance of heater 18 may be correlated with the temperature of heater 18. The temperature sensor can measure the current and / or voltage applied to heater 18 (or induction coil). Based on the measured current and / or voltage, the impedance of heater 18 can be calculated. The control unit 12 can estimate the temperature of heater 18 based on the calculated impedance.

[0032] As an example, the temperature sensor may include a resistive element (e.g., a thermistor) whose resistance value changes in response to temperature changes in the heaters 18 and 24. The temperature sensor may output a signal corresponding to the resistance value of the resistive element, and the control unit 12 may detect the temperature and / or temperature changes of the heaters 18 and 24 based on the aforementioned signal corresponding to the resistance value.

[0033] As another example, the temperature sensor may include a sensor that detects the resistance value of heaters 18 and 24. The temperature sensor may output a signal corresponding to the resistance value of heaters 18 and 24, and the control unit 12 may detect the temperature and / or temperature change of heaters 18 and 24 based on the aforementioned signal corresponding to the resistance value.

[0034] According to one embodiment, a temperature sensor can sense the temperature of the power supply 11. The temperature sensor can be arranged adjacent to the power supply 11. For example, the temperature sensor can be attached to a surface of the power supply 11 (e.g., a battery) and / or mounted on a surface of a printed circuit board. As an example, the aerosol generating apparatus 1 may include a power protection circuit (PCM), and the temperature sensor can be arranged adjacent to the power supply 11 together with the power protection circuit.

[0035] According to one embodiment, the temperature sensor may also be arranged inside the housing (not shown) of the aerosol generating device 1 to sense the temperature inside the housing (not shown).

[0036] According to one embodiment, the suction sensor can sense the user's suction.

[0037] As an example, the suction sensor may include a pressure sensor. The pressure sensor can output a signal corresponding to the internal pressure of the aerosol generating device 1, and the control unit 12 can detect the user's suction based on the aforementioned signal corresponding to the internal pressure. The internal pressure of the aerosol generating device 1 may correspond to the pressure of the gas flow channel. The suction sensor may be arranged in the aerosol generating device 1 corresponding to the gas flow channel.

[0038] As another example, the suction sensor may include a temperature sensor. When a user performs suction, a temporary temperature drop may occur in the airflow channel, the space where the aerosol-generating article is inserted (hereinafter referred to as the insertion space), heaters 18, 24, etc. The control unit 12 can detect the user's suction based on a signal output from the temperature sensor corresponding to the temperature of the airflow channel, etc.

[0039] As another example, the suction sensor may include both a pressure sensor and a temperature sensor. In this case, the temperature sensor can measure the temperature used to correct the internal pressure measured by the pressure sensor. As an example, the suction sensor can correct the signal corresponding to the internal pressure based on the temperature measured by the temperature sensor and output the corrected signal. As another example, the suction sensor can output both a signal corresponding to the temperature measured by the temperature sensor and a signal corresponding to the internal pressure measured by the suction sensor. In this case, the control unit 12 can receive the signals and correct the signal corresponding to the internal pressure based on the signal corresponding to the temperature.

[0040] As another example, the suction sensor may include a capacitive sensor. In this disclosure, a capacitive sensor may also be referred to as a cap sensor or capacitive sensor. When a user performs suction, temperature changes and / or aerosol flow may occur within the insertion space of the aerosol-generating article, thereby potentially changing the dielectric constant inside the insertion space. The control unit 12 can detect the user's suction based on a signal output from the capacitive sensor corresponding to the dielectric constant, etc., inside the insertion space.

[0041] The suction sensor is not limited to the examples above and can be implemented by a variety of sensors used to sense a user's suction.

[0042] According to one embodiment, the insertion sensing sensor is capable of sensing the insertion and / or removal of an aerosol-generating article. The insertion sensing sensor may be disposed around the periphery of the insertion space. Furthermore, the insertion sensing sensor may also include any combination of the examples described above.

[0043] As an example, the insertion sensing sensor may include a capacitive sensor. The capacitive sensor may include at least one conductor, and the at least one conductor may be arranged adjacent to the insertion space.

The control unit 12 may detect the insertion and / or removal of the aerosol-generating article based on a signal output from the capacitive sensor corresponding to the dielectric constant, etc., inside the insertion space.

[0044] As another example, the insertion sensing sensor may include an inductive sensor. The inductive sensor may include at least one coil, and the at least one coil may be arranged adjacent to the insertion space. When the aerosol generating article (e.g., a wrapper of the aerosol generating article) includes a conductor, a change in the magnetic field may be generated around the coil through which the current flows when the aerosol generating article is inserted into or removed from the insertion space. The control unit 12 may sense the insertion and / or removal of the aerosol generating article including the conductor based on the characteristics of the current output from or sensed by the inductive sensor (e.g., the frequency, current value, voltage value, inductance value, impedance value, etc. of the alternating current). Alternatively, an inductive heating element (SUS) may also be included in the aerosol generating article (e.g., the dielectric portion of the aerosol generating article). Even in this case, the magnetic field around the coil may change based on the insertion or removal of the heating element or the like in the insertion space, and the control unit 12 can sense the insertion and / or removal of the aerosol generating article based on the current characteristics of the inductive sensor.

[0045] The insertion sensing sensor is not limited to the examples described above, and can be implemented by various sensors (e.g., proximity sensors) used to sense the insertion and / or removal of aerosol-generating articles. Furthermore, the insertion sensing sensor can also include any combination of the examples described above. According to one embodiment, the insertion sensing sensor may also include a switch, etc., for sensing pressure generated by the aerosol-generating article.

[0046] According to one embodiment, a reuse sensing sensor can detect whether an aerosol-generating article has been reused. As an example, the reuse sensing sensor can be a color sensor for sensing the color of the aerosol-generating article. If a user uses the aerosol-generating article, the color of a portion of the outer casing of the aerosol-generating article may change due to the generated aerosol or heating. The color sensor can output a signal corresponding to the optical characteristics (e.g., wavelength of light) of the color of the outer casing based on the light reflected from it. If a color change is detected in a portion of the outer casing, the control unit 12 can determine that the aerosol-generating article inserted into the insertion space has been used.

[0047] According to one embodiment, an over-humidity sensing sensor can sense whether an aerosol-generating article is in an over-humid state. For example, the over-humidity sensing sensor may include a capacitive sensor. The capacitive sensor may include at least one conductor arranged adjacent to the insertion space. The control unit 12 can detect whether the aerosol-generating article is in an over-humid state based on the level of a signal corresponding to the dielectric constant, etc., output from the capacitive sensor. As an example, the control unit 12 can confirm the level range that the signal level falls into according to a lookup table, and determine the moisture content of the aerosol-generating article based on the confirmed level range.

[0048] According to one embodiment, the cigarette identification sensor can sense whether the aerosol-generating article is genuine and / or the type of aerosol-generating article.

[0049] As an example, a cigarette identification sensor may include a light sensor for sensing an identification substance (or identification mark) located on the outer surface (e.g., packaging component) of an aerosol-generating article. The light sensor may illuminate the identification substance (or identification mark) of the aerosol-generating article and sense whether the aerosol-generating article is genuine and / or its type based on the reflected light. For example, the identification substance may include a substance that emits light of a specific wavelength based on the illuminated light. The control unit 12 may detect whether the aerosol-generating article is genuine and / or its type based on the range of said wavelengths.

[0050] As another example, the cigarette identification sensor may include a capacitive sensor. Depending on the type of aerosol-generating article inserted into the insertion space, the dielectric constant inside the insertion space may vary. The control unit 12 can detect whether the aerosol-generating article is genuine and / or its type based on a signal output from the capacitive sensor corresponding to the dielectric constant, etc., inside the insertion space.

[0051] As another example, a cigarette identification sensor may include an inductive sensor. When the packaging and / or interior (e.g., the dielectric portion) of the aerosol-generating article inserted into the insertion space includes a conductor, the characteristics of the current sensed by the inductive sensor (e.g., frequency, current value, voltage value, inductance value, impedance value, etc.) may vary depending on the type of aerosol-generating article inserted into the insertion space. The control unit 12 can detect whether the inserted aerosol-generating article is genuine and / or its type based on the characteristics of the current output from or sensed by the inductive sensor.

[0052] Cigarette identification sensors are not limited to the examples described above and can be implemented using various sensors for sensing whether an aerosol-generating article is genuine and / or for sensing the type of aerosol-generating article. Furthermore, cigarette identification sensors can also include any combination of the examples described above.

[0053] According to one embodiment, the cartridge sensing sensor can sense the installation and / or removal of the cartridge. For example, the cartridge sensing sensor may include an inductive sensor, a capacitive sensor, a resistive sensor, a Hall effect sensor (Hall IC), and / or an optical sensor.

[0054] According to one embodiment, the cap sensing sensor can sense the installation and / or removal of the cap. For example, the cap sensing sensor may include an inductive sensor, a capacitive sensor, a resistive sensor, a contact sensor, a Hall effect sensor (HAL IC), and / or an optical sensor. The cap may include a structure that covers at least a portion of a cartridge mounted or inserted into the aerosol generating device 1, or covers at least a portion of the housing of the aerosol generating device 1. If the cap is installed in or removed from the housing, the cap sensing sensor can output a signal corresponding to the installation or removal, and the control unit 12 can sense the installation or removal of the cap based on the signal corresponding to the installation or removal.

[0055] According to one embodiment, the motion sensing sensor is capable of sensing the motion of the aerosol generating device 1. The motion sensing sensor can be implemented by at least one of an accelerometer and a gyroscope.

[0056] According to one embodiment, in addition to the sensors described above, the sensor unit 13 may also include at least one of a humidity sensor, a barometric pressure sensor, a magnetic sensor, a position sensor (Global Positioning System (GPS)), or a proximity sensor. Since a person skilled in the art can intuitively infer the function of each sensor from its name, detailed descriptions are omitted.

[0057] According to one embodiment, the output unit 14 can output information about the status of the aerosol generating device 1. The output unit 14 may include, but is not limited to, a display, a haptic unit, and / or an audio output unit. For example, the information about the aerosol generating device 1 may include the charging / discharging status of the power supply 11, the preheating status of the heaters 18 and 24, the insertion / removal status of the aerosol generating article and / or cartridge, the installation and / or removal status of the cover, or a status where the use of the aerosol generating device 1 is restricted (e.g., abnormal object detected). The display can visually provide the user with information about the status of the aerosol generating device 1. For example, the display may include a light-emitting diode (LED), a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. If the display includes a touchpad, the display can also be used as an input unit 15. The haptic unit can tactilely provide the user with information about the status of the aerosol generating device 1. For example, the tactile part may include a vibrating motor, a piezoelectric element, an electrical stimulation device, etc. The sound output part can provide the user with information about the aerosol generating device 1 in an auditory manner. For example, the sound output part can convert an electrical signal into a sound signal and output the sound signal to the outside.

[0058] According to one embodiment, the power source 11 can supply power for the operation of the aerosol generating apparatus 1. The power source 11 may include one or more batteries. The power source 11 can supply power to heat the heaters 18 and 24. Furthermore, the power source 11 can supply power required for the operation of other components included in the aerosol generating apparatus 1, such as the control unit 12, sensor unit 13, output unit 14, input unit 15, communication unit 16, and memory 17. The power source 11 can be a rechargeable battery or a disposable battery. For example, the power source 11 can be a lithium polymer (LiPoly) battery, but is not limited thereto. The power source 11 can be a replaceable (detachable) battery (hereinafter, a removable battery). The removable battery can be installed in a battery housing provided within the aerosol generating apparatus 1, or it can be removed from the battery housing. The removable battery can be charged via wired and / or wireless means.

[0059] According to one embodiment, heaters 18 and 24 receive power from power source 11, thereby enabling them to heat the aerosol generating article and / or the medium and / or aerosol generating substance within the cartridge. The aerosol generating apparatus 1 may include heater 18 for heating the aerosol generating article and / or cartridge heater 24 for heating the cartridge (i.e., the solid and / or liquid medium).

[0060] According to one embodiment, heaters 18 and 24 can be resistance heaters. For example, resistance heaters can include resistive materials such as metals or metal alloys like titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, and nichrome. Resistance heaters can be implemented using metal heating wires, metal heating plates with conductive tracks, or ceramic heating elements.

[0061] According to one embodiment, heaters 18 and 24 can be induction heating heaters. For example, an induction heating heater may include an induction heating element (susceptor) that heats up by a magnetic field. An alternating current flowing through an induction coil can generate a magnetic field in the induction coil. The generated magnetic field can pass through the heater and can generate eddy currents in the induction heating element. Based on the generation of eddy currents, the induction heating element can be heated. According to one embodiment, the induction heating element may also be included inside an aerosol generating article (e.g., a medium section).

[0066] According to one embodiment, the control unit 12 can control the entire operation of the aerosol generating device 1. For example, the control unit 12 may include at least one processor. The control unit 12 may be implemented by an array of multiple logic gates, or by a combination of a general-purpose microcontroller (MCU) (or microprocessor) and a memory storing a program that can be executed in the MCU. Furthermore, it will be understood by those skilled in the art to which this embodiment pertains that the control unit may also be implemented by other forms of hardware.

[0067] According to one embodiment, the control unit 12 can control the temperature of heaters 18 and 24 by controlling the power supply 11 to supply power to heaters 18 and 24. The control unit 12 can control the temperature of heaters 18 and 24 and / or the power supplied to heaters 18 and 24 based on the temperature of heaters 18 and 24 sensed by a temperature sensor (e.g., sensor unit 13). The control unit 12 can also control the temperature of heaters 18 and 24 and / or the power supplied to heaters 18 and 24 based on temperature curves and / or power curves stored in the memory 17.

[0068] According to one embodiment, the control unit 12 can control the power (e.g., voltage and / or current) supplied to the heaters 18 and 24 by controlling a power conversion circuit (not shown) electrically connected to the heaters 18 and 24 and the power supply 11. For example, the power conversion circuit may include a DC / DC converter (e.g., a buck converter, buck-boost converter, boost converter, Zener diode, etc.) for converting the power supplied to the heaters 18 and 24, and a DC / AC converter (e.g., an inverter) for converting the power supplied to the induction coil (not shown). The DC / AC converter can be implemented using a full-bridge circuit or a half-bridge circuit including multiple switching elements. For example, the power conversion circuit may include at least one switching element such as a bipolar junction transistor (BJT), a field-effect transistor (FET), etc.

[0069] According to one embodiment, the control unit 12 can regulate the current and / or voltage supplied to the heaters 18 and 24 by adjusting the frequency and / or duty ratio of the current pulses input to at least one switching element of the power conversion circuit (not shown). The duty ratio of the on / off operation of the switching element can correspond to the ratio of the output voltage of the power conversion circuit to the output voltage of the power supply 11.

[0070] According to one embodiment, the control unit 12 can control the power supplied to the heaters 18 and 24 using at least one of pulse width modulation (PWM) and proportional-integral-differential (PID) methods. For example, the control unit 12 can use PWM to supply current pulses with a predetermined frequency and duty cycle to the heaters 18 and 24. The control unit 12 can control the power supplied to the heaters 18 and 24 by adjusting the frequency and duty cycle of the current pulses. For example, the control unit 12 can determine the target temperature as the control objective based on a temperature curve. The control unit 12 can use PID to control the power supplied to the heaters 18 and 24, which is a feedback control method based on the difference between the temperature of the heaters 18 and 24 and the target temperature, the integral value of the difference over time, and the derivative value of the difference over time.

[0071] According to one embodiment, the control unit 12 can determine the target power as a control objective based on the power curve. Over time, the control unit 12 can control the power supplied to the heaters 18 and 24 to correspond to the preset target power.

[0072] According to one embodiment, the control unit 12 can detect user suction by sensing the power supplied to the heaters 18 and 24. More specifically, the control unit 12 can use a PID control method to control the power supplied to the heaters 18 and 24. When a user performs suction, a temporary temperature drop may occur in the space where the aerosol-generating article is inserted (hereinafter referred to as the insertion space), the heaters 18 and 24, etc. Therefore, during the PID power control, the power (or current) supplied to the heaters 18 and 24 may change. The control unit 12 can detect user suction based on the controlled power change.

[0073] According to one embodiment, the control unit 12 can prevent the heaters 18 and 24 from overheating. For example, the control unit 12 can control the operation of the power conversion circuit based on the temperature of the heaters 18 and 24 exceeding a preset limit temperature, so as to reduce the power supplied to the heaters 18 and 24 or interrupt the power supply to the heaters 18 and 24.

[0074] According to one embodiment, the control unit 12 can control the charging / discharging of the power supply 11. For example, the control unit 12 can use a temperature sensor (e.g., sensor unit 13) to determine the temperature of the power supply 11. When the temperature of the power supply 11 exceeds a first limit temperature, the control unit 12 can cut off the charging of the power supply 11. When the temperature of the power supply 11 exceeds a second limit temperature, the control unit 12 can interrupt the use of the power stored in the power supply 11 (e.g., discharging). The control unit 12 can calculate the remaining capacity of the power stored in the power supply 11. For example, the control unit 12 can calculate the remaining capacity of the power supply 11 based on the voltage and / or current detection values ​​of the power supply 11.

[0075] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on the results sensed by the sensor unit 13.

[0076] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on the insertion and / or removal of the aerosol-generating article relative to the insertion space. For example, if the insertion sensing sensor (e.g., sensor unit 13) determines that the aerosol-generating article has been inserted into the insertion space, the control unit 12 can control the supply of power to the heaters 18 and 24. If the insertion sensing sensor (e.g., sensor unit 13) determines that the aerosol-generating article has been removed from the insertion space, the control unit 12 can cut off the power supply to the heaters 18 and 24. If the temperature of the heaters 18 and 24 is above a limit temperature or the temperature change slope of the heaters 18 and 24 is above a set slope, the control unit 12 can determine that the aerosol-generating article has been removed from the insertion space.

[0077] According to one embodiment, the control unit 12 can control the power supply time and / or power supply amount to the heaters 18 and 24 based on the state of the aerosol generating article. For example, if the aerosol generating article is determined to be in an over-humidity state by using an over-humidity sensing sensor (e.g., sensor unit 13), the control unit 12 can increase the power supply time (e.g., preheating time) to the heaters 18 and 24.

[0078] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on whether the aerosol-generating article has been reused. For example, if the control unit 12 determines that the aerosol-generating article has been used, it can cut off the power supply to the heaters 18 and 24.

[0079] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on whether the cartridge is attached and / or removed. For example, if the cartridge sensing sensor (e.g., sensor unit 13) determines that the cartridge is in a separated state, the control unit 12 can control the interruption of the power supply to the heaters 18 and 24 or prevent the supply of power to the heaters 18 and 24.

[0080] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on whether the aerosol-generating material of the cartridge has been depleted. For example, if the control unit 12 determines that the temperature of the heaters 18 and 24 exceeds a limit temperature during the preheating period (i.e., the preheating interval), it can determine that the aerosol-generating material of the cartridge has been depleted. In the case that the aerosol-generating material of the cartridge has been depleted, the control unit 12 can cut off the power supply to the heaters 18 and 24.

[0081] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on whether the e-cigarette cartridge is available. For example, if the control unit 12 determines, based on data stored in the memory 17, that the current number of puffs exceeds the maximum number of puffs set for the e-cigarette cartridge, it can determine that the e-cigarette cartridge cannot be used. Alternatively, the control unit 12 can determine that the e-cigarette cartridge cannot be used if the total heating time of the heaters 18 and 24 exceeds a preset maximum time or if the total electrical power supplied to the heaters 18 and 24 exceeds a preset maximum electrical power. In this case, the control unit 12 can control the power supply to the heaters 18 and 24 to be interrupted or not to be supplied with power.

[0082] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on the user's suction. For example, the control unit 12 can use a suction sensor (e.g., sensor unit 13) to determine whether suction has occurred and / or the intensity of suction. If the number of suctions has reached a preset maximum number of suctions and / or no suction is detected for a preset time, the control unit 12 can cut off the power supply to the heaters 18 and 24. When suction is detected, the control unit 12 can control the power supply to the heaters 18 and 24.

[0083] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on whether the aerosol-generating article (or cartridge) is genuine and / or its type. For example, the control unit 12 can use a cigarette identification sensor (e.g., sensor unit 13) to detect whether the aerosol-generating article is genuine and / or its type. As an example, if the aerosol-generating article (or cartridge) is detected to be counterfeit, the control unit 12 can cut off the power supply to the heaters 18 and 24. If the aerosol-generating article (or cartridge) is detected to be genuine, the control unit 12 can control (e.g., start) the power supply to the heaters 18 and 24. As another example, the control unit 12 can control the power supply to the heaters 18 and 24 in different ways depending on the type of aerosol-generating article (or cartridge). More specifically, if the aerosol generating article (or cartridge) is detected as a first aerosol generating article (or first cartridge), the control unit 12 can control the temperature and / or power of the heaters 18 and 24 based on a first temperature curve (or first power curve). If the aerosol generating article (or cartridge) is detected as a second aerosol generating article (or second cartridge), the control unit 12 can control the temperature and / or power of the heaters 18 and 24 based on a second temperature curve (or second power curve).

[0084] According to one embodiment, the control unit 12 can control the output unit 14 based on the results sensed by the sensor unit 13. For example, if the number of suctions counted by the suction sensor (e.g., sensor unit 13) reaches a preset number, the control unit 12 can control the output unit 14 to provide information that the aerosol generating device 1 is about to end its operation in a visual, tactile, and / or audible manner. For example, the control unit 12 can control the output unit 14 to provide information about the temperature of the heaters 18 and 24 in a visual, tactile, and / or audible manner.

[0085] According to one embodiment, the control unit 12 can store and update the history of events that have occurred in the memory 17 based on the occurrence of predetermined events. For example, events may include operations performed in the aerosol generating apparatus 1 such as sensing the insertion of an aerosol generating article, starting heating of the aerosol generating article, sensing suction, ending suction, sensing overheating of heaters 18 and 24, sensing overvoltage applied to heaters 18 and 24, ending heating of the aerosol generating article, turning the power supply of the aerosol generating apparatus 1 on / off, starting charging of the power supply 11, sensing overcharging of the power supply 11, and ending charging of the power supply 11. For example, the history of events may include the date and time of the event, log data corresponding to the event, etc. For example, if the predetermined event is sensing the insertion of an aerosol generating article, the log data corresponding to the event may include data such as the sensing value of the insertion sensing sensor (e.g., sensor unit 13). For example, if the predetermined event is the sensing of overheating of heaters 18 and 24, the log data corresponding to the event may include data about the temperature of heaters 18 and 24, the voltage applied to heaters 18 and 24, the current flowing in heaters 18 and 24, etc.

[0086] According to one embodiment, the control unit 12 can control the communication unit 16 to form a communication link with an external device such as a user's mobile terminal.

[0087] According to one embodiment, if authentication data is received from an external device via a communication link, the control unit 12 can remove usage restrictions on at least one function of the aerosol generating device 1 (e.g., heating function). For example, the authentication data may include the user's birthday, a unique phone number representing the user, and whether the user has completed authentication.

[0088] According to one embodiment, the control unit 12 can send data about the status of the aerosol generating device 1 (e.g., remaining capacity of the power supply 11, operating mode, etc.) to an external device via a communication link. The sent data can be output through a display or the like on the external device.

[0089] According to one embodiment, if a location search request for the aerosol generating device 1 is received from an external device via a communication link, the control unit 12 can control the output unit 14 to perform an operation corresponding to the location search. For example, the control unit 12 can control the tactile unit to vibrate, or control the display to output objects corresponding to the location search and the end of the search.

[0090] According to one embodiment, if firmware data is received from an external device via a communication link, the control unit 12 can perform a firmware update.

[0091] According to one embodiment, the control unit 12 can send data about the detection values ​​of at least one sensor unit 13 to an external server (not shown) via a communication link, and can receive and store a learning model generated by learning the detection values ​​through machine learning such as deep learning from the server. The control unit 12 can use the learning model received from the server to perform operations such as determining the user's inhalation pattern and generating a temperature curve.

[0092] Although Figure 1 Although not shown, the aerosol generating device 1 may also include a power protection circuit. The power protection circuit may include at least one switching element and may disconnect the power supply 11 in response to overcharging and / or over-discharging. The aerosol generating device 1 may also include a connection interface such as a universal serial bus (USB) interface, and may be connected to other external devices via the connection interface to send and receive information or charge the power supply 11.

[0093] The aerosol generating article mentioned in this disclosure may include at least one aerosol generating rod (e.g., a medium section) and at least one filter rod. The heater 18 may be arranged corresponding to at least one aerosol generating rod and may be designed differently depending on the arrangement and / or position of the aerosol generating rod and the filter rod. The aerosol generating rod may contain at least one of nicotine, an aerosol generating substance, and additives. For example, the aerosol generating substance may contain glycerin (e.g., vegetable glycerin (VG)) and / or propylene glycol (PG), or may contain a variety of other substances. For example, the additive may contain flavoring agents and / or organic acids, or may contain a variety of other substances. For example, the aerosol generating rod may contain an aerosol generating substrate (e.g., a sheet) impregnated with a liquid non-tobacco substance (e.g., the aerosol generating substance and / or nicotine), and / or may contain solid tobacco substances (e.g., tobacco leaves, reconstituted tobacco, etc.). Tobacco substances can be contained in the aerosol generating rod in various forms such as shreds, granules, and powder. According to one embodiment, the additives in the aerosol generating rod may contain an alkaline substance. Based on the alkaline substance, the nicotine in the tobacco substances contained in the aerosol generating rod can have an alkaline pH value (e.g., pH 7.0 or higher). In this case, the aerosol generating rod can release free base nicotine even at lower temperatures. According to one embodiment, the aerosol generating rod may comprise two or more aerosol generating rods, and the two or more aerosol generating rods may each contain tobacco substances and / or non-tobacco substances. Additionally, although not shown, at least one aerosol generating rod and at least one filter rod may each be wrapped by at least one wrapper, and / or wrapped together by at least one wrapper. In this disclosure, the aerosol generating article may also be referred to as a stick.

[0094] The cartridge mentioned in this disclosure may contain an aerosol-generating substance in any of the following states: liquid, solid, gaseous, or gel. The aerosol-generating substance may comprise a liquid composition. For example, the liquid composition may be a liquid containing substances found in tobacco (including volatile tobacco flavor components) or a liquid containing non-tobacco substances. Additionally, the cartridge may include a storage section for containing the aerosol-generating substance and / or a liquid delivery member for impregnating (containing) the aerosol-generating substance. For example, the liquid delivery member may include a core material such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic. The cartridge heater 24 may be included in the cartridge in the form of a coil surrounding (or winding) the liquid delivery member or in a structure contacting one side of the liquid delivery member. Alternatively, the cartridge heater 24 may also be included in an aerosol-generating device 1 that can be separated from the cartridge.

[0095] Figure 2a An aerosol generating apparatus 1 according to one embodiment is shown. Figure 2b An aerosol generating apparatus 1 according to one embodiment is shown.

[0096] According to one embodiment, the aerosol generating device 1 may include a housing 10, a power supply 11, a control unit 12, a sensor unit 13, and / or heaters 182, 183 (e.g., Figure 1 (The heater 18). However, those skilled in the art will understand that the components of the aerosol generating apparatus 1 are not limited to those described in this embodiment. Figure 2a or Figure 2b The constituent elements shown can be omitted or new constituent elements can be added. Figure 2a The aerosol generating device 1 shown can be referred to as an "internal heating type" aerosol generating device that heats the inside of the aerosol generating article 2. Figure 2b The aerosol generating device 1 shown can be referred to as an "externally heated" aerosol generating device that heats the outside of the aerosol generating article 2. In the following figures, details related to... Figure 1 Repeated explanation.

[0097] According to one embodiment, the housing 10 may provide an upwardly opening space for insertion of the aerosol generating article 2. In this disclosure, the upwardly opening space may be referred to as an insertion space. The insertion space may be recessed into the interior of the housing 10 to a predetermined depth to allow insertion of at least a portion of the aerosol generating article 2. The depth of the insertion space may be greater than the length of the region of the aerosol generating article 2 containing the aerosol generating substance and / or medium. The lower end of the aerosol generating article 2 may be inserted into the interior of the housing 10, and the upper end of the aerosol generating article 2 may protrude outward from the housing 10. A user may hold the exposed upper end of the aerosol generating article 2 in their mouth and inhale the aerosol.

[0098] According to one embodiment, heaters 182 and 183 can heat the aerosol-generated article 2.

[0099] Reference Figure 2a Heater 182 can be an internal heating type heater.

[0100] According to one embodiment, the internally heated heater can extend relatively far upward within the space (i.e., the insertion space) into which the aerosol-generating article 2 is inserted. For example, as shown, the internally heated heater can include rod-shaped or needle-shaped heating elements, but can also include various heating elements such as tubular or plate-shaped heating elements. The internally heated heater can be inserted through the lower part of the aerosol-generating article 2.

[0101] According to one embodiment, an internally heated heater may include a resistance heater and / or an induction heater.

[0102] For example, the resistance heater may include a resistive material on its inner side (e.g., an internal hollow or inner surface) or outer side (e.g., an outer surface), and can be heated as an electric current flows through the resistive material. In this case, the resistance heater may be electrically connected to the power supply 11 and can be heated directly by receiving current from the power supply 11. Furthermore, the induction coil 181 may be omitted.

[0103] For example, for an induction heating heater, the aerosol generating device 1 may include an induction coil 181 surrounding at least a portion of an internal heating type heater (e.g., arranged externally in a manner corresponding to at least a portion of the heater's length). In this case, to improve the efficiency of induction heating, a magnetic flux concentrator or similar device may also be included outside the induction coil 181. The induction heating heater may include an induction heating element (susceptor) and may generate heat based on a magnetic field generated from the induction coil 181. According to one embodiment, the induction heating heater (e.g., an induction heating element) (or a heater module including it) may be arranged to be detachable from the housing 10.

[0104] According to one embodiment, heater 182 can also be a multiple heater. The multiple heaters may include a first heater and a second heater, and can be inserted into the aerosol generating article 2. The first and second heaters can be arranged side-by-side along the length direction. The first and second heaters can operate as resistance heaters and / or induction heaters, and can be heated sequentially or simultaneously. In this case, the first and second heaters can be arranged respectively at positions corresponding to the length directions of two or more aerosol generating rods. Alternatively, the first and second heaters can also be arranged respectively at positions corresponding to the length directions of a first and second part of an aerosol generating rod. Furthermore, when heater 182 is an induction heater, the aerosol generating device 1 may include a first induction coil and a second induction coil, which can also be arranged respectively at positions corresponding to the length directions of the first and second heaters. Alternatively, the first and second heaters can also be arranged respectively at positions corresponding to the length directions of a first and second part of a heater 182. In addition, heaters and / or induction coils may include three or more.

[0105] According to one embodiment, the induction heating element is arranged (or contained) inside the aerosol generating article 2 (e.g., the medium section), and can be implemented to heat the induction heating element contained inside the aerosol generating article 2 based on the magnetic field generated from the induction coil 181.

[0106] Reference Figure 2b Heater 183 can be an external heating type heater.

[0107] According to one embodiment, the externally heated heater can extend upwardly and relatively long around the space where the aerosol generating article 2 is inserted (i.e., the insertion space). For example, the externally heated heater can be arranged to surround at least a portion of the insertion space. As an example, the externally heated heater can include a tubular shape (e.g., cylindrical) with a hollow interior. The externally heated heater can also include a shape with a hollow interior that surrounds the hollow space. In this case, the externally heated heater can be supported by a polyimide film. A heater supported by such a film can be referred to as a film heater. The externally heated heater can be arranged to surround at least a portion of the insertion space. The externally heated heater is capable of heating the outside of the aerosol generating article 2 inserted into the hollow space.

[0108] According to one embodiment, the external heating type heater may include a resistance heater and / or an induction heater, and the terms related to... will be omitted. Figure 2a To reiterate. Furthermore, for induction heating heaters, the aerosol generating apparatus 1 may include an external heating type heater formed by a tubular induction heating element, and may include an induction coil 181 surrounding at least a portion of the external heating type heater (e.g., arranged externally in a manner corresponding to at least a portion of the heater's length). Additionally, the induction coil 181 may also include a fan coil. Furthermore, if the external heating type heater is a resistance heater, since heating can be achieved by current flowing through the tubular resistance heater (e.g., a thin-film heater), a separate induction coil 181 can be omitted. Additionally, insulating material may be arranged externally to the external heating type heater. This reduces the heat dissipated from the heater 183 in the radially outward direction and applied to the outside of the housing 10.

[0109] According to one embodiment, heater 183 can be multiple heaters, with the first and second heaters arranged side-by-side along the length direction and each surrounding at least a portion of the insertion space. The first and second heaters can operate as resistance heaters and / or induction heaters, and can be heated sequentially or simultaneously. Alternatively, when heater 183 is an induction heater, the aerosol generating device 1 can include a first induction coil and a second induction coil, which can be arranged respectively at positions corresponding to the length directions of the first and second heaters. Alternatively, the first and second heaters can also be arranged respectively at positions corresponding to the length directions of a first and a second portion of heater 183.

[0110] and Figure 2a or Figure 2b The situation shown is different, Figure 2a heater 182 and Figure 2b The heater 183 can be included in the aerosol generating apparatus 1. In this case, the heater 182 can heat the inside of the aerosol generating article 2, and the heater 183 can heat the outside of the aerosol generating article 2.

[0111] According to one embodiment, an airflow channel for air circulation can be provided in the aerosol generating apparatus 1. For example, the housing 10 may include a structure (e.g., a hole) that allows air to flow from the outside into the interior of the housing 10. The air flowing into the interior of the housing 10 can enter the aerosol generating article 2 through its lower end (i.e., upstream side). The aerosol generated by heating the aerosol generating article 2 can be inhaled into the user's mouth along with the inflowing air through its upper end (i.e., downstream side).

[0112] Figure 3 An aerosol generating apparatus 1 according to one embodiment is shown.

[0113] According to one embodiment, the aerosol generating device 1 may include a housing 10, a power supply 11, a control unit 12, a sensor unit 13, and / or heaters 183, 24 (e.g., Figure 1 (Heats 18, 24). However, those skilled in the art will understand that the components of the aerosol generating apparatus 1 are not limited to those described in this embodiment. Figure 3 The constituent elements shown may be partially omitted, or new constituent elements may be added. In the following figures, those omitted and... Figure 1 Repeated explanation.

[0114] According to one embodiment, the housing 10 may provide an upwardly opening space (hereinafter referred to as an insertion space) for inserting the aerosol generating article 2. The insertion space may be recessed into the interior of the housing 10 to a predetermined depth to allow at least a portion of the aerosol generating article 2 to be inserted. The lower end of the aerosol generating article 2 may be inserted into the interior of the housing 10, and the upper end of the aerosol generating article 2 may protrude outward from the housing 10.

[0115] Unlike the case shown in the attached figures, the cartridge 19 may also provide an insertion space for accommodating the aerosol generating article 2. In this case, the insertion space may be recessed into the interior of the cartridge 19 to a predetermined depth, allowing at least a portion of the aerosol generating article 2 to be inserted. The lower end of the aerosol generating article 2 may be inserted into the interior of the cartridge 19, while the upper end of the aerosol generating article 2 may protrude outward from the cartridge 19. Furthermore, in this case, the aerosol generating device 1 may not include the heater 183.

[0116] According to one embodiment, the depth of the insertion space can be greater than the length of the region of the aerosol generating article 2 containing the aerosol generating substance and / or medium. The user can hold the exposed upper end of the aerosol generating article 2 in their mouth and inhale air.

[0117] According to one embodiment, heater 183 can heat aerosol generating article 2. Heater 183 can extend relatively long upwards around the periphery of the space into which aerosol generating article 2 is inserted (i.e., the insertion space). As an example, heater 183 can be a tubular shape (e.g., cylindrical) with a hollow interior. Heater 183 can also include a shape with a hollow interior that encloses the hollow space. In this case, heater 183 can be supported by a polyimide film. A heater supported by such a film can be referred to as a film heater. Heater 183 can be arranged to surround at least a portion of the insertion space. Heater 183 can heat the outside of the hollow aerosol generating article 2 inserted therein. In this disclosure, heater 183 can be referred to as an external heating type heater that heats the outside of the aerosol generating article 2. Additionally, an insulating material can also be arranged on the outside of heater 183. This reduces the heat dissipated from heater 183 in a radially outward direction and applied to the outside of housing 10.

[0118] According to one embodiment, heater 183 may include a resistance heater and / or an induction heater.

[0119] For example, a resistance heater may include a resistive material and can be heated as an electric current flows through it. In this case, the resistance heater may be electrically connected to power source 11 and can be heated directly by receiving current from power source 11.

[0120] For example, for an induction heating heater, the aerosol generating device 1 may further include an induction coil (not shown) surrounding at least a portion of the heater 183 (e.g., arranged externally in a manner corresponding to at least a portion of the length of the heater 183). In this case, to improve the efficiency of induction heating, a magnetic flux concentrator or the like may also be included outside the induction coil (not shown). The induction heating heater may include an induction heating element (susceptor) and may generate heat based on a magnetic field generated from the induction coil (not shown).

[0121] According to one embodiment, heater 183 can also be a multiple heater. The multiple heaters may include a first heater and a second heater, and can be inserted into the aerosol generating article 2. The first and second heaters can be arranged side-by-side along the length direction. The first and second heaters can operate as resistance heaters and / or induction heaters, and can be heated sequentially or simultaneously. In this case, the first and second heaters can be arranged respectively at positions corresponding to the length directions of two or more aerosol generating rods. Alternatively, the first and second heaters can also be arranged respectively at positions corresponding to the length directions of a first and second part of an aerosol generating rod. Furthermore, when heater 183 is an induction heater, the aerosol generating device 1 may include a first induction coil and a second induction coil, which can also be arranged respectively at positions corresponding to the length directions of the first and second heaters. Alternatively, the first and second heaters can also be arranged respectively at positions corresponding to the length directions of a first and second part of a heater 183. In addition, heaters and / or induction coils may include three or more.

[0122] Unlike the case shown in the attached diagram, the aerosol generating device 1 may also exclude the heater 183. The aerosol generating article 2 may be directly or indirectly heated by the cartridge heater 24, or substantially unheated. Indirect heating means that the aerosol generating article 2 receives heat contained within the aerosol as it passes through the cartridge heater 24. In this case, the aerosol generating device 1 may be referred to as a non-heating (or, indirectly heated) aerosol generating device. The aerosol generating rod of the aerosol generating article 2 may contain additives such as alkaline substances. Based on this alkaline substance, the nicotine contained in the aerosol generating rod may have an alkaline pH (e.g., pH 7.0 or higher). This alkaline nicotine can flow into the user's mouth along with the aerosol flowing from the cartridge 19 into the aerosol generating article 2, as described later.

[0123] Unlike the case shown in the attached figures, heater 183 may also include an internally heated type heater. For example, an internally heated type heater may include various heating elements such as rod-type, tubular-type, plate-type, or needle-type heating elements. The internally heated type heater can be inserted through the lower part of the aerosol generating article 2 and can be configured to heat the inner side of the aerosol generating article 2.

[0124] According to one embodiment, the cartridge 19 can be detachably attached to the housing 10. For example, a space can be formed on one side of the housing 10, and at least a portion of the cartridge 19 can be inserted into the space formed on one side of the housing 10, so that the cartridge 19 can be installed in the housing 10. Alternatively, the cartridge 19 can be integrally formed with the housing 10.

[0125] According to one embodiment, an airflow channel for air circulation can be provided in the aerosol generating device 1 and / or the cartridge 19. For example, the housing 10 may include a structure that allows air to flow from the outside into the interior of the housing 10 when the cartridge 19 is inserted. The inflowing air can pass through the cartridge 19 and flow into the insertion space through the airflow channel CN, and can flow into the user's mouth. The airflow channel CN ​​may also include various structures for reducing residual droplets or promoting airflow.

[0126] exist Figure 3 Although the illustration shows the cartridge 19 positioned to the side of the aerosol generating article 2 and the airflow channel CN ​​forming from the side surface of the aerosol generating article 2 toward the lower end (i.e., the upstream side) of the aerosol generating article 2, the positions of the cartridge 19 and the airflow channel CN ​​are not limited to this. For example, the cartridge 19 may be positioned adjacent to the lower end (i.e., the upstream side) of the aerosol generating article 2, and in this case, the airflow channel CN ​​may be formed substantially in a straight line to connect the cartridge 19 to the lower end (i.e., the upstream side) of the aerosol generating article 2.

[0127] According to one embodiment, the cartridge 19 may include a storage section C0 containing aerosol-generating material, a cartridge heater 24, and / or a liquid delivery member impregnated with (containing) aerosol-generating material. The liquid delivery member is capable of being impregnated with aerosol-generating material supplied from the chamber C0. For example, the liquid delivery member may include a core material such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0128] According to one embodiment, the cartridge heater 24 can heat the aerosol-generating material contained in the cartridge 19. For example, the cartridge heater 24 may include a resistance heater and / or an induction heater.

[0129] As an example, a resistance heater may include a resistive material and can be heated as an electric current flows through it. As another example, for an induction heater, the aerosol generating device 1 may also include an induction coil (not shown) around the periphery of the induction heater. The induction heater may include an induction heating element and can generate heat based on a magnetic field generated from the induction coil (not shown). The cartridge heater 24 can be formed in a coil configuration surrounding (or winding around) the liquid delivery member and / or in contact with one side of the liquid delivery member (e.g., a patterned shape).

[0130] Unlike the case shown in the attached figures, the cartridge heater 24 may also be included in the aerosol generating device 1. For example, the cartridge heater 24 may be included inside the housing 10. In this case, the cartridge 19 can be separated from the cartridge heater 24 by removing the cartridge 19.

[0131] According to one embodiment, an aerosol can be generated based on the heating of the cartridge heater 24. For example, as the aerosol generating material impregnated in the liquid delivery member is heated by the cartridge heater 24, vapor can be generated from the aerosol generating material, and as the generated vapor mixes with external air flowing into the cartridge 19, an aerosol can be generated. The aerosol generated by the cartridge heater 24 flows into the aerosol generating article 2 through the airflow channel CN. As the aerosol passes through the aerosol generating article 2, tobacco or flavoring substances can be added to the aerosol, and the aerosol with added tobacco or flavoring substances can be inhaled into the user's mouth through one end of the aerosol generating article 2.

[0132] Figure 4 A cross-sectional view of an aerosol generating apparatus according to an embodiment is shown.

[0133] Reference Figure 4 One embodiment of the aerosol generating apparatus 400 may include a housing 410, at least one humidity sensor 440, and a heater 450. The constituent elements of the aerosol generating apparatus 400 may be similar to... Figure 2a , Figure 2b or Figure 3 At least one of the components of the aerosol generating device 1 is the same or similar, and repeated descriptions will be omitted below. Here, the humidity-sensitive resistor sensor is a sensor used to sense humidity, and can also be called a humidity sensor.

[0134] In one embodiment, the housing 410 forms the overall appearance of the aerosol generating device 400, and an internal space can be formed inside the housing 410 for housing components of the aerosol generating device 400. For example, a humidity sensor 440 and a heater 450 can be installed in the internal space of the housing 410, but it is not limited thereto.

[0135] In one embodiment, the housing 410 may include an opening 405, and at least a portion of the aerosol-generating article M may be inserted into or accommodated within the housing 410 through the opening 405. Only an embodiment in which the opening 405 is located in the upper region of the housing 410 is shown in the figures, but the embodiment is not limited thereto; according to the embodiment, the opening 405 may also be located on the side of the housing 410.

[0136] In one embodiment, the membrane 460 (or "base membrane") may be made of polyimide (PI) having heat resistance or insulation properties. For example, the membrane 460 may form the base of the heater 450 and the humidity sensor 440, and may be configured to surround the outer peripheral surface of the aerosol generating article M inserted through the receiving portion 415.

[0137] In one embodiment, a heater 450 is disposed on one side of the membrane 460 and located within the interior space of the housing 410. It heats an aerosol-generating article M inserted through the opening 405 into or contained within the receiving portion 415 of the housing 410 to generate an aerosol. For example, the heater 450 can generate heat when powered and heat the aerosol-generating article M inserted into or contained within the receiving portion 415. Vaporized particles generated by heating the aerosol-generating article M mix with air, thereby generating an aerosol.

[0138] In one embodiment, the humidity-sensitive resistor sensor 440 is disposed on one side of the membrane 460 and located inside the housing 410, similar to the heater 450. It can sense the humidity of the aerosol-generating article M inserted through the opening 405 or housed in the receiving portion 415 of the housing 410. For example, the humidity-sensitive resistor sensor 440 can sense the humidity based on the moisture contained in the aerosol-generating article using two electrodes and convert the sensed humidity into an electrical signal.

[0139] In one example, the humidity sensor 440 may include a resistive humidity sensor. For instance, the humidity sensor 440 may include two electrodes and a conductive layer made of a low-resistivity material. The conductive layer may be deposited to cover the top of the two electrodes, which may be patterned to increase the contact area. Furthermore, as the conductive layer absorbs moisture contained in the aerosol-generating article M, the resistance between the two electrodes may change, and the humidity sensor 440 may sense the relative humidity by detecting this resistance change.

[0140] In another example, the humidity sensor 440 may include a capacitive humidity sensor. For instance, the humidity sensor 440 may include two electrodes and a dielectric layer (or insulating layer) made of a non-conductive polymer. The dielectric layer may be deposited between the two electrodes, which may be patterned to increase the contact area. Furthermore, as the dielectric layer absorbs moisture contained in the aerosol-generating article M, its dielectric constant may change, and the humidity sensor 440 can sense relative humidity by the voltage between the two electrodes that varies according to the change in the dielectric constant.

[0141] In another example, the humidity sensor 440 may include a thermally conductive humidity sensor. For instance, the humidity sensor 440 may include a first thermistor sealed in a chamber filled with dry nitrogen and a second thermistor disposed in an open chamber. When the humidity sensor 440 is powered, the resistances of the first and second thermistors can be calculated, and the absolute humidity can be sensed by the calculated resistance difference.

[0142] In one embodiment, the humidity-sensitive resistor sensor 440 may include: a first sensor, in a first direction (e.g., Figure 4 A first portion of the membrane 460 is spaced apart from the heater 450 in the y-direction and disposed thereon; and a second sensor is disposed in the second direction (e.g., in the y-direction) in the first portion of the membrane 460, and in the second direction (e.g., in the y-direction); and a second sensor is disposed in the second direction (e.g., in the y-direction) in the first portion of the membrane 460, and is space Figure 4 It is spaced apart from the heater in the -y direction and positioned in the second part of membrane 460. (This will be discussed later.) Figure 5 The Chinese side will provide a detailed explanation of this.

[0143] In one embodiment, the humidity-sensitive resistor sensor 440 may be disposed on the membrane 460 in a manner that does not overlap with the heater 450, and may function to sense the humidity of the aerosol-generating article M inserted into the receiving portion 415. For example, the humidity-sensitive resistor sensor 440 may include at least one electrode pattern disposed in a manner that does not overlap with the heating pattern of the heater 450.

[0144] In this invention, the statement "the humidity sensor 440 is arranged in a manner that does not overlap with the heater 450" can mean that when viewed radially from the membrane 460, the humidity sensor 440 and the heater 450 are arranged in a structure that does not overlap.

[0145] In one embodiment, the aerosol generating apparatus 400 may further include a battery 420 and a processor 430.

[0146] Battery 420 can supply the power required for the operation of aerosol generating device 400. For example, battery 420 can power heater 450 to enable heater 450 to heat up. As another example, battery 420 can supply the power required for the operation of processor 430, or it can also supply the power required for the operation of humidity sensor 440.

[0147] The processor 430 can control the overall operation of the aerosol generating device 400.

[0148] For example, processor 430 may be electrically and / or operatively connected to heater 450 to control its operation. That is, processor 430 may control the power supply to heater 3450 based on a predetermined heating temperature profile.

[0149] In this invention, the term "operationally connected" may refer to a state in which the constituent elements are connected to transmit and receive signals wirelessly, or transmit and receive optical signals and / or magnetic signals, etc., and this term may be used in the same sense below.

[0150] For example, the processor 430 can control its operation by being electrically and / or operatively connected to the humidity sensor 440. That is, the processor 430 can determine a heating temperature profile suitable for the heater 450 based on the humidity of the aerosol-generating article M sensed by the humidity sensor 440, or control the cutting off of power supply to the heater 450.

[0151] In one embodiment, the processor 430 may be disposed or mounted on a printed circuit board (not shown) located within the internal space of the housing 410, and may be electrically or operatively connected to the heater 450 and / or the humidity sensor 440 via electrical connection components (e.g., cables, C-clamps, FPCBs, etc.) that connect the printed circuit board to the heater 450 and / or the humidity sensor 440. However, the configuration of the processor 430 is not limited to the above embodiment, and the configuration of the processor 430 may be varied according to the embodiment.

[0152] Figure 5 This is a diagram showing the arrangement structure of the heater and humidity-sensitive resistor sensor in the membrane unfolded state according to an embodiment. Figure 6 Show Figure 5 The diagram shows a three-dimensional view of the setup of the heater and humidity sensor when the membrane is fully wound.

[0153] Reference Figure 5 and Figure 6 Including heaters (e.g., Figure 4 The heater 450) and the humidity-sensitive resistor sensor (e.g., Figure 4 The arrangement 500 of the humidity-sensitive resistor sensor 440 can be formed such that a heater 540 and two humidity-sensitive resistor sensors 520 and 530 are disposed on the membrane 510. Figure 5 and Figure 6 The arrangement 500 shown can be applicable to Figure 2a , Figure 2b and Figure 3An embodiment of the heater in the aerosol generating apparatus 1 is described below, and repeated descriptions will be omitted below.

[0154] In one embodiment, the array 500 may include a membrane 510, a first humidity-sensitive resistor sensor 520, a second humidity-sensitive resistor sensor 530, and a heater 540.

[0155] In one embodiment, such as Figure 5 As shown, when the array 500 is in the unfolded state, the heater 540 can be disposed in a region of the membrane 510. For example, the heater 540 may include a resistive pattern made of a metallic material, and the first terminal 542 and the second terminal 544 at both ends can be connected to a battery (e.g., Figure 4 The battery 420 is electrically connected to receive power supplied from the battery. Additionally, a heater 540 may be positioned at the center of the membrane 510.

[0156] In one embodiment, such as Figure 5 As shown, when the array 500 is in the unfolded state, the first humidity-sensitive resistor sensor 520 and the second humidity-sensitive resistor sensor 530 are respectively disposed in the first and second portions of the membrane 510. For example, the first humidity-sensitive resistor sensor 520 and the second humidity-sensitive resistor sensor 530 may include a first electrode and a second electrode respectively in a comb-like shape. The comb-like first electrode and the second electrode may be configured to mesh with each other in a relative manner.

[0157] The first terminals 522 and 524 at both ends of the first humidity-sensitive resistor sensor 520 and the first terminals 532 and 534 at both ends of the second humidity-sensitive resistor sensor 530 can receive power supplied from the battery 420 through electrical connection. Additionally, the first humidity-sensitive resistor sensor 520 can be positioned in a first direction (e.g., Figure 5 The second humidity sensor 530 is spaced apart from the heater 540 and disposed in the upper region of the membrane 510 in the y-direction, and can be located in a second direction opposite to the first direction (e.g., in the y-direction). Figure 5 It is spaced apart from the heater 540 and disposed in the lower end region of the membrane 510 in the -y direction.

[0158] However, the arrangement structure of the arrangement body 500 is not limited to this. In another embodiment, if at least one of the first humidity-sensitive resistor sensor 520 and the second humidity-sensitive resistor sensor 530 is arranged not to overlap with the heater 540, it can also be arranged to extend to the center of the membrane 510.

[0159] In one embodiment, the first humidity sensor 520 and the second humidity sensor 530 can function to sense inserted aerosol-generating articles (e.g., Figure 4The aerosol generating article M) is affected by humidity. For example, the first humidity-sensitive resistor sensor 520 and the second humidity-sensitive resistor sensor 530 may include two electrodes respectively printed or mounted on the membrane 510, and the aerosol generating device (e.g., Figure 4 The aerosol generating device 400 can sense humidity changes and / or humidity values ​​based on the magnitude and / or frequency of electrical signals sensed by two electrodes.

[0160] In one embodiment, the first humidity sensor 520 and the second humidity sensor 530 are arranged in a manner that does not overlap with the heater 540. When the first humidity sensor 520 and the second humidity sensor 530 overlap with the heater 540, the detection sensitivity of the first humidity sensor 520 and the second humidity sensor 530 may decrease due to the heat generated in the heater 540, causing sensor damage. Conversely, as shown in the arrangement 500 of one embodiment, by arranging the first humidity sensor 520 and the second humidity sensor 530 to not overlap with the heater 540, sensor damage or malfunction, decreased detection sensitivity, etc., caused by the heat generated in the heater 540 can be prevented.

[0161] In one embodiment, the array 500 can be formed by winding an unfolded membrane 510 into a cylindrical shape with an internally hollow interior.

[0162] For example, in Figure 5 In the membrane 510, one end of the membrane 510 adjacent to the first humidity sensor 520 and the heater 540 and the other end of the membrane 510 adjacent to the second humidity sensor 530 and the heater 540 can be rolled up.

[0163] at this time, Figure 6 The diagram shows the film 510 wound so that the exposed surfaces of the first humidity sensor 520, the second humidity sensor 530, and the heater 540 form the outer peripheral surface of the array 500, but it is not limited to this. For example, the film 510 may also be wound so that the exposed surfaces of the first humidity sensor 520, the second humidity sensor 530, and the heater 540 form the inner peripheral surface of the array 500.

[0164] like Figure 6 As shown, when the membrane 510 is fully wound, it can be formed into a tubular shape with a circular or elliptical cross-section, which is an arrangement 500. The arrangement 500, which is a hollow cylindrical shape, can be arranged inside the aerosol generating device 400 in a manner that surrounds the outer peripheral surface of the aerosol generating article M, and can heat the aerosol generating article M when power is supplied to the heater 540.

[0165] One embodiment of the aerosol generating apparatus 400 can utilize the arrangement structure of the aforementioned arrangement 500 without requiring a separate configuration for mounting the humidity sensors 520 and 530, thus making it more economical in terms of manufacturing cost. Furthermore, the space occupied by the humidity sensors 520 and 530 within the aerosol generating apparatus 400 can be minimized, thereby contributing to the miniaturization of the apparatus.

[0166] Figure 7 A cross-sectional view of a membrane arranged in a manner surrounding an aerosol-generating article is shown in one embodiment.

[0167] Reference Figure 7 The aerosol generating article 750 includes: a medium section 752 containing tobacco material; and a filter section 754 coupled to the downstream end of the medium section 752, and the arrangement body 700 can be formed by placing a heater 720 and a humidity sensor 730 on the membrane 710.

[0168] In one embodiment, the medium portion 752 may contain an aerosol-generating substance. For example, the aerosol-generating substance may include at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. Additionally, the medium portion 752 may contain other additives, such as flavoring agents, humectants, and / or organic acids. Furthermore, the medium portion 752 may be flavored by spraying with a fragrance liquid such as menthol or a humectant.

[0169] In one embodiment, the dielectric portion 752 can be manufactured in various ways. For example, the dielectric portion 752 can be manufactured as a sheet or as a strand. Alternatively, the dielectric portion 752 can also be made from shredded tobacco leaves. Furthermore, the dielectric portion 752 can be surrounded by a heat-conducting material. For example, the heat-conducting material can be a metal foil such as aluminum foil, but is not limited thereto. As an example, the heat-conducting material surrounding the dielectric portion 752 can uniformly distribute the heat transferred to the dielectric portion 752, thereby increasing the thermal conductivity applied to the dielectric portion 752, which can enhance the tobacco flavor. Additionally, the heat-conducting material surrounding the dielectric portion 752 can function as a sensor heated by an induction coil.

[0170] In one embodiment, the filter section 754 may be made of cellulose acetate. Furthermore, the shape of the filter section 754 is not limited. For example, the filter section 754 may be a cylindrical rod or a tubular rod containing a hollow portion inside. Alternatively, the filter section 754 may be an embedded rod. If the filter section 754 is composed of multiple segments, at least one of the segments may also be manufactured in different shapes.

[0171] In one embodiment, the filter section 754 may be configured to produce a fragrance. For example, a fragrance liquid may be sprayed onto the filter section 754, and individual fibers coated with the fragrance liquid may be inserted into the interior of the filter section 754.

[0172] In one embodiment, when the filter section 754 includes a cooling section for cooling aerosols, the cooling section may be made of a polymeric material or a biodegradable polymeric material. For example, the cooling section may be manufactured by weaving a bundle of fibers composed of a polymeric material or a biodegradable polymeric material. The cooling section may be made of pure polylactic acid, but is not limited thereto. Alternatively, the cooling section may be made of a cellulose acetate filter having at least one perforation. However, the cooling section is not limited to the above examples and is not limited as long as it functions to cool aerosols.

[0173] In one embodiment, the filter section 754 may include a moisture-sensitive material (not shown). The moisture-sensitive material may be made of a material that absorbs ambient moisture, and may be a conductive polymer. For example, the moisture-sensitive material may be made of at least one of lithium chloride (LiCl) and aluminum oxide (Al2O3), and is not limited thereto.

[0174] In this invention, the filter section 754 includes a humidity-sensitive material, thereby improving the detection sensitivity of the humidity-sensitive resistor sensor 730. Compared to the material constituting the medium section 752, the material constituting the filter section 754 absorbs ambient moisture to a practically lower degree. The humidity-sensitive resistor sensor 730 is arranged around the filter section 754 of the aerosol-generating article 750, so the humidity-sensitive resistor sensor 730 can sense the humidity of the filter section 754 even within the aerosol-generating article 750. Since the filter section 754 includes a humidity-sensitive material that absorbs ambient moisture (e.g., moisture contained in the medium section 752, moisture absorbed from the outside, etc.), the humidity-sensitive material can act as a moisture core material, and the humidity-sensitive resistor sensor 730 can sense the humidity of the filter section 754 with higher sensing sensitivity by sensing the humidity of the moisture-sensitive material containing moisture.

[0175] In addition, the aerosol generating apparatus of the present invention (e.g., Figure 4 The aerosol generating device 400 can accurately determine whether the state of the aerosol generating article 750 is excessively humid, normal, or excessively dry.

[0176] In one embodiment, the moisture-sensitive material can be contained in the filter section 754 in various shapes and disposed in multiple locations. For example, the moisture-sensitive material can be contained in the filter section 754 in a cylindrical shape extending through the center of the filter section 754 along the length of the aerosol generating article 750. As another example, the moisture-sensitive material can also be contained in the filter section 754 in a tubular shape surrounding the outer peripheral surface of the filter section 754. However, it is not limited to these embodiments; the moisture-sensitive material can be disposed in various shapes at locations where it can absorb ambient moisture.

[0177] In one embodiment, the cylindrical arrangement 700 formed by winding the membrane 710 in one direction can be arranged to surround the aerosol generating article 750. The heater 720 can be arranged to surround the medium portion 752 of the aerosol generating article 750, and the humidity-sensitive resistor sensor 730 can be arranged to surround the filter portion 754 of the aerosol generating article 750.

[0178] For example, in order to generate aerosols via the heating medium section 752, a heater 720 may be provided in the first part of the medium section 752 surrounding the aerosol generating article 750 of the membrane 710. Additionally, in order to detect the humidity of the filter section 754, a humidity-sensitive resistor sensor 730 may be provided in the second part of the filter section 754 surrounding the aerosol generating article 750 of the membrane 710.

[0179] Figure 8 A cross-sectional view of a membrane arranged in a manner surrounding an article of aerosol generation, according to another embodiment, is shown. Figure 8 In the specific explanation, descriptions that correspond to, are the same as or similar to the aforementioned content may be omitted.

[0180] Reference Figure 8 The aerosol generating article 850 may include: a front-end insert 852; a medium section 854 containing tobacco material; and a filter section 856, positioned opposite to the front-end insert 852 with the medium section 854 as the center. The arrangement body 800 can be formed by providing a heater 840 and two humidity sensors 820 and 830 on the membrane 810. In this case, the medium section 854 and the filter section 856 can be... Figure 7 The media section 752 and the filter section 754 have the same constituent elements.

[0181] In one embodiment, the front-end insert 852 may include a hollow portion for introducing external air to form a mainstream smoke inside the aerosol-generating article 850. For example, the hollow portion formed in the front-end insert 852 may have a circular cross-section. However, it is not limited thereto, and the hollow portion formed in the front-end insert 852 may have various cross-sections. For example, the hollow portion formed in the front-end insert 852 may also have a Y-shaped cross-section.

[0182] In one embodiment, the front-end plug 852 may be made of cellulose acetate. For example, the front-end plug 852 may be manufactured by adding a plasticizer (such as triacetin) to the cellulose acetate tow. The front-end plug 852 prevents the media portion 854 from detaching to the outside and prevents impurities from flowing into the media portion 854 from the outside.

[0183] In one embodiment, at least one of the front-end plug 852 and the filter section 856 may include a humidity-sensitive material (not shown). The humidity-sensitive material may be composed of a material that absorbs ambient moisture, and may be a conductive polymer. For example, the humidity-sensitive material may be composed of at least one of lithium chloride (LiCl) and alumina (Al2O3), and is not limited thereto.

[0184] In one embodiment, the moisture-sensitive material can be contained in the front-end insert 852 and / or the filter section 856 in various shapes, and can also be disposed in multiple locations. For example, the moisture-sensitive material can be disposed in the front-end insert 852 in a tubular shape, penetrating the hollow portion of the front-end insert 852. As another example, the moisture-sensitive material can be contained in the filter section 856 in a cylindrical shape, penetrating the center of the filter section 856 along the length direction of the aerosol generating article 850. As yet another example, the moisture-sensitive material can also be contained in the front-end insert 852 and / or the filter section 856 in a tubular shape surrounding the outer peripheral surface of the front-end insert 852 and / or the filter section 856. However, it is not limited to these embodiments; the moisture-sensitive material can be disposed in various shapes at locations where it can absorb ambient moisture.

[0185] In one embodiment, the cylindrical arrangement 800 formed by winding the membrane 810 in one direction can be arranged to surround the aerosol generating article 850. The heater 840 can be arranged to surround the medium portion 854 of the aerosol generating article 850, and the first humidity sensor 820 and the second humidity sensor 830 can be arranged to surround the front-end insert 852 and the filter portion 856 of the aerosol generating article 850, respectively.

[0186] For example, in order to generate an aerosol by heating the medium section 854, the heater 840 may be provided at the center of the medium section 854 surrounding the aerosol generating article 850 of the membrane 810.

[0187] Additionally, to detect the humidity of the front-end plug 852, a first humidity-sensitive resistor sensor 820 may be disposed on a first portion of the membrane 810 surrounding the front-end plug 852 of the aerosol generating article 850. In this case, the first portion may refer to a first direction (e.g., Figure 5 The portion of the heater 840 that is disposed on the membrane 810 in the y direction is spaced apart from the central portion of the membrane 810.

[0188] Additionally, to detect the humidity of the filter section 856, a second humidity-sensitive resistor sensor 830 may be disposed on a second portion of the filter section 856 surrounding the aerosol generating article 850 of the membrane 810. In this case, the second portion may refer to a second direction (e.g., Figure 5 The portion of the heater 840 that is disposed on the membrane 810 in the -y direction is spaced apart from the central portion of the membrane 810.

[0189] Figure 9 A cross-sectional view of a membrane arranged in a manner surrounding an article of aerosol generation, according to another embodiment, is shown. Figure 9 In the specific explanation, descriptions that correspond to, are the same as or similar to the aforementioned content may be omitted.

[0190] Reference Figure 9 The aerosol generating article 950 may include: a front-end insert 952; a medium section 954 containing tobacco material; and a filter section 956, positioned opposite to the front-end insert 952 with the medium section 954 as the center. The arrangement 900 can be formed by providing a heater 940 and two humidity sensors 920 and 930 on the membrane 910. In this case, the front-end insert 952, the medium section 954, and the filter section 956 can be... Figure 8 It has the same constituent elements as the front-end plug-in 852, media section 854 and filter section 856.

[0191] In one embodiment, the cylindrical arrangement 900 formed by winding the membrane 910 in one direction can be arranged to surround the aerosol generating article 950. The heater 940 can be arranged to surround a portion of the medium portion 954 of the aerosol generating article 950, and the first humidity sensor 920 and the second humidity sensor 930 can be arranged to surround the front-end insert 952 and the filter portion 956 of the aerosol generating article 950, respectively. Furthermore, the first humidity sensor 920 can be arranged to surround the remaining area of ​​the medium portion 954 adjacent to the front-end insert 952, and the second humidity sensor 930 can be arranged to surround the remaining area of ​​the medium portion 954 adjacent to the filter portion 956.

[0192] For example, in order to generate an aerosol by heating the medium section 954, the heater 940 may be provided in the center of a portion of the medium section 954 surrounding the aerosol generating article 950 of the membrane 910.

[0193] Additionally, to detect the humidity of a portion of the front-end plug 952 and the medium portion 954, a first humidity-sensitive resistor sensor 920 may be disposed in a first portion of the area adjacent to the front-end plug 952 within the membrane 910 surrounding the aerosol generating article 950 and the medium portion 954. In this case, the first portion may refer to a first direction (e.g., Figure 5The portion of the membrane 910 that is spaced apart from the central portion of the heater 940 in the y direction.

[0194] Additionally, to detect the humidity of a portion of the filter section 956 and the medium section 954, a second humidity-sensitive resistor sensor 930 may be disposed in a second portion of the region of the membrane 910 surrounding the filter section 956 and the medium section 954 of the aerosol generating article 950, adjacent to the filter section 956. In this case, the second portion may refer to a second direction (e.g., Figure 5 The portion of the heater 940 that is disposed on the membrane 910 in the -y direction is spaced apart from the central portion of the membrane 910.

[0195] The first humidity-sensitive resistor sensor 920 and the second humidity-sensitive resistor sensor 930 are respectively arranged around a portion of the medium section 954, thereby enabling more accurate detection of the humidity of the aerosol-generating article 950. Compared to the materials constituting the front-end insert 952 and the filter section 956, the material constituting the medium section 954 can absorb ambient moisture to a practically higher degree, thus allowing for sensitive application of humidity changes in the aerosol-generating article 950 to the medium section 954. This provides a more accurate representation of the humidity changes in the medium section 954. Figure 9 The arrangement of the structure shown in the diagram 900 can detect not only the humidity of the front-end plug 952 and the filter section 956, but also the humidity of the medium section 954, thus improving the accuracy of humidity detection.

[0196] Figure 10 A flowchart illustrating a control action based on humidity sensed by a humidity-sensitive resistor sensor of an aerosol generating apparatus is shown to explain one embodiment.

[0197] Reference Figure 10 In action 1010, the processor (e.g., Figure 4 The processor 430) can be accessed via a humidity-sensitive resistor sensor (e.g., Figure 4 The humidity-sensitive resistor sensor 440 is used to sense aerosol-generating articles (e.g., Figure 4 The humidity of the aerosol-generating article M. For example, the processor 430 can sense the humidity based on the moisture contained in the aerosol-generating article M through electrodes included in the humidity-sensitive resistor sensor 440, and can convert the sensed humidity into an electrical signal.

[0198] According to one embodiment, in action 1020, processor 430 may control the heater (e.g., based on the sensed humidity of the aerosol-generating article M). Figure 4 The heater (450) is powered by electricity.

[0199] In one embodiment, the processor 430 can determine whether the sensed humidity of the aerosol-generating article M is within a preset range. Here, the preset range may refer to the humidity range in which the humidity state of the aerosol-generating article is judged to be normal, and may be an electrical signal range (e.g., resistance value, voltage value, etc.).

[0200] In one embodiment, when the humidity of the sensed aerosol generating article M is within a preset range, the processor 430 can supply power to the heater 450 based on a first temperature curve; when it is below or above the preset range, the processor 430 can supply power to the heater 450 based on a second temperature curve different from the first temperature curve.

[0201] For example, at the start of the aerosol generation device (e.g., Figure 4 Before the heating operation of the aerosol generating device 400, the humidity of the aerosol generating article M is sensed by the humidity-sensitive resistor sensor 440. When the sensed humidity of the aerosol generating article M is within a preset range, the processor 430 can supply power to the heater 450 based on a first temperature curve. At this time, the first temperature curve is a temperature curve used for heating the aerosol generating article M in a normal state, and may include a heating range, a temperature holding range, and a cooling range.

[0202] For example, before the heating operation of the aerosol generating device 400 begins, the humidity of the aerosol generating article M is sensed by a humidity-sensitive resistor sensor 440. When the sensed humidity of the aerosol generating article M is lower or higher than a preset range, the processor 430 can supply power to the heater 450 based on a second temperature curve. At this time, the second temperature curve is a temperature curve used to heat the aerosol generating article M in an overly humid and / or overly dry state, and may include a heating range, a temperature holding range, and a cooling range.

[0203] Furthermore, at least one of the heating range, temperature holding range, and cooling range of the second temperature curve may be longer or shorter than the heating range, temperature holding range, and cooling range of the first temperature curve. For example, the heating range of the second temperature curve may be longer than the heating range of the first temperature curve.

[0204] However, the first and second temperature profiles described above are merely examples and are not limited thereto. In another embodiment, the first and second temperature profiles can be modified in various ways according to the manufacturer's design.

[0205] In one embodiment, when the humidity of the sensed aerosol generating article M is within a preset range, the processor 430 can supply power to the heater 450, and when it is below or above the preset range, the power supply to the heater 450 can be cut off.

[0206] For example, after the heating operation of the aerosol generating device 400 is started, the humidity of the aerosol generating article M is sensed by the humidity-sensitive resistor sensor 440. When the sensed humidity of the aerosol generating article M is within a preset range, the processor 430 can supply power to the heater 450.

[0207] For example, after the heating operation of the aerosol generating device 400 is started, the humidity of the aerosol generating article M is sensed by the humidity-sensitive resistor sensor 440. When the sensed humidity of the aerosol generating article M is lower or higher than a preset range, the processor 430 can cut off the power supply to the heater 450.

[0208] The embodiments of this disclosure described above, or other embodiments, are not mutually exclusive or distinct from each other.
