[0032] refer to Figures 1 to 4 According to one embodiment, the aerosol generation system 100 may include an aerosol generation device 1 and an aerosol generation article S.

[0033] refer to Figure 1 and Figure 2 The aerosol generating device 1 may include one or more of a power supply 11, a control unit 12, a sensor 13, and a vaporizer 19. One or more of the power supply 11, control unit 12, and sensor 13 may be arranged inside the housing 10 of the aerosol generating device 1. The housing 10 provides a space open to one side to allow insertion of the aerosol generating article S. This space open to one side may be referred to as the internal space 104. The internal space 104 may be recessed into the housing 10 to a predetermined depth to allow insertion of at least a portion of the aerosol generating article S. The depth of the insertion space may correspond to the length of the region in the aerosol generating article S containing the aerosol generating substance and / or medium. The upstream end of the aerosol generating article S may be inserted into the housing 10, while the downstream end of the aerosol generating article S may protrude from the outside of the housing 10. A user can inhale air by holding the exposed downstream end of the aerosol generating article S in their mouth.

[0034] The vaporizer 19 may contain aerosol-generating substances in any of the following states: liquid, solid, gas, or gel. The aerosol-generating substances may include liquid compositions. For example, the liquid composition may be a liquid containing tobacco-containing substances, including volatile tobacco aroma components, or it may be a liquid containing non-tobacco-containing substances. The vaporizer 19 may be integrally formed with the housing 10 or detachably attached to the housing 10.

[0035] For example, refer to Figure 1 The vaporizer 19 is integrated with the housing 10 and can be connected to the internal space 104 through the airflow channel CN.

[0036] For example, refer to Figure 2 A space is formed on one side of the housing 10, and at least a portion of the vaporizer 19 is inserted into the space formed on one side of the housing 10, so that the vaporizer 19 can be fixed to the housing 10. The airflow passage CN may be defined by a portion of the vaporizer 19 and / or a portion of the housing 10, and the vaporizer 19 can communicate with the internal space 104 through the airflow passage CN.

[0037] The housing 10 can be formed by a structure that allows external air to flow into the housing 10 when the carburetor 19 is inserted. At this time, the external air flowing into the housing 10 can pass through the carburetor 19 and flow into the user's mouth.

[0038] The vaporizer 19 may include a storage section C0 for containing aerosol-generating substances and / or a heater 191 for heating the aerosol-generating substances in the storage section C0.

The conductive track of the heater 191 may be formed as a coil structure wound around the liquid delivery member or a structure contacting one side of the liquid delivery member. The heater 191 may be referred to as a vaporizer heater 191.

[0039] The vaporizer 19 is capable of generating an aerosol. An aerosol is generated when the liquid transport component is heated by the vaporizer heater 191. An aerosol can be generated by heating the aerosol generating article S through the vaporizer heater 191. When the aerosol generated by the vaporizer heater 191 passes through the aerosol generating article S, tobacco substances can be incorporated into the aerosol, and the tobacco-infused aerosol is inhaled into the user's mouth through one end of the aerosol generating article S.

[0040] The aerosol generating device 1 may include a cover (not shown). The cover is detachably attached to the housing 10 to cover at least a portion of the vaporizer 19 connected to the housing 10. The aerosol generating article S may penetrate the cover and be inserted into the housing 10.

[0041] Power source 11 supplies the power required for the operation of the components of aerosol generating device 1. Power source 11 may be referred to as a battery. Power source 11 can supply power to one or more of the control unit 12, sensor 13, and vaporizer heater 191.

[0042] The control unit 12 can control the overall operation of the aerosol generating device. The control unit 12 can be mounted on a printed circuit board (PCB). The control unit 12 can control the operation of at least one of the power supply 11, sensor 13, and vaporizer 19. The control unit 12 can control the operation of the display, motor, etc., installed in the aerosol generating device 1. The control unit 12 can check the status of each component of the aerosol generating device 1 to determine whether the aerosol generating device is in an operational state.

[0043] The control unit 12 can analyze the detection results of the sensor 13 and control the subsequent processing. For example, the control unit 12 can control the power supplied to the vaporizer heater 191 based on the results detected by the sensor 13, thereby starting and stopping the vaporizer heater 191. For example, the control unit 12 can control the power supplied to the vaporizer heater 191 and the power supply time based on the results detected by the sensor 13, so as to heat the vaporizer heater 191 to a predetermined temperature or maintain it at an appropriate temperature.

[0044] Sensor 13 may include one or more of a temperature sensor, a puff sensor, an insertion detection sensor, a color sensor, a cartridge detection sensor, and a cap detection sensor. For example, sensor 13 may detect one or more of the temperature of the vaporizer heater 191, the temperature of the power supply 11, and the internal and external temperatures of the housing 10. For example, sensor 13 may sense a user's puff. For example, sensor 13 may sense whether the aerosol generating article S has been inserted into the internal space 104. For example, sensor 13 may sense whether the vaporizer 19 has been installed. For example, sensor 13 may sense whether the cap has been installed.

[0045] The outer casing 10 may include a first surface 101, a second surface 102 opposite to the first surface 101, and a side surface 103 located between the first surface 101 and the second surface 102. The first surface 101 may have an internal space 104. The internal space 104 may include an internal space end surface 1042 located between the first surface 101 and the second surface 102, and an internal space side surface 1043 extending from the edge of the internal space end surface 1042 to the first surface 101.

[0046] The first sensor 13-1 and the second sensor 13-2 can be along the length direction of the internal space 104 (e.g., along...). Figure 1 and Figure 2 Arranged in the -X direction.

[0047] The control unit 12 receives first information measured by the first sensor 13-1 and second information measured by the second sensor 13-2, and can determine the state of the aerosol-generating article S based on the first and second information. The first sensor 13-1 and the second sensor 13-2 will be described in detail later.

[0049] Sensor 13 can detect the status of aerosol generating device 1 or the surrounding environment of aerosol generating device 1, and transmit the detected information to control unit 12. Control unit 12 can control aerosol generating device 1 to perform multiple functions based on the detected information, such as controlling the operation of vaporizer heater 191, restricting smoking, determining whether aerosol generating article S and / or vaporizer 19 has been inserted, and displaying notifications.

[0050] Sensor 13 may include one or more of the following: temperature sensor 131, suction sensor 132, insertion detection sensor 133, reusability detection sensor 134, cartridge detection sensor (vaporizer detection sensor) 135, cap detection sensor 136, and motion detection sensor 137.

[0051] Temperature sensor 131 can detect the heating temperature of vaporizer heater 191. Aerosol generating apparatus 1 may include a separate temperature sensor to detect the temperature of vaporizer heater 191, or vaporizer heater 191 itself may be used as a temperature sensor.

[0052] Temperature sensor 131 can output a signal corresponding to the temperature of carburetor heater 191. For example, temperature sensor 131 may include a resistive element whose resistance value changes according to the temperature of carburetor heater 191. This resistive element can be implemented as a thermistor, which utilizes the characteristic that resistance changes with temperature. In this case, temperature sensor 131 can output a signal corresponding to the resistance value of the resistive element as a signal corresponding to the temperature of carburetor heater 191. For example, temperature sensor 131 may be constructed by a sensor that detects the resistance value of carburetor heater 191. In this case, temperature sensor 131 outputs a signal corresponding to the resistance value of carburetor heater 191 as a signal corresponding to the temperature of carburetor heater 191.

[0053] Temperature sensor 131 can be arranged around power supply 11 to monitor the temperature of power supply 11. Temperature sensor 131 can be arranged adjacent to power supply 11. For example, temperature sensor 131 can be attached to one side of the battery used as power supply 11. For example, temperature sensor 131 can be mounted on one side of a printed circuit board.

[0054] Temperature sensor 131 can be arranged inside housing 10 to detect the internal temperature of housing 10.

[0055] The suction sensor 132 can detect user suction based on various physical changes in the airflow path. The suction sensor 132 can output a signal corresponding to suction. For example, the suction sensor 132 can be a pressure sensor. The suction sensor 132 can output a signal corresponding to the internal pressure of the aerosol generating device 1. The internal pressure of the aerosol generating device 1 can correspond to the pressure of the airflow path supplying the gas. The suction sensor 132 can be positioned corresponding to the airflow path of the aerosol generating device 1.

[0056] Insertion detection sensor 133 can detect the insertion and / or removal of aerosol-generating article S. Insertion detection sensor 133 can detect signal changes during insertion and / or removal of aerosol-generating article S. Insertion detection sensor 133 can be mounted around the insertion space. Insertion detection sensor 133 can detect the insertion and / or removal of aerosol-generating article S based on changes in the dielectric constant within the insertion space. For example, insertion detection sensor 133 can be an inductive sensor and / or a capacitive (electrostatic) sensor.

[0057] An inductive sensor may include at least one coil. The coil of an inductive sensor may be arranged adjacent to the internal space. For example, when a change occurs in the magnetic field around the coil through which current flows, the characteristics of the current flowing through the coil will change according to Faraday's law of electromagnetic induction. The characteristics of the current flowing in the coil may include the frequency, current value, voltage value, inductance value, impedance value, etc., of the alternating current.

[0058] Inductive sensors can output a signal that corresponds to the characteristics of the current flowing in a coil. For example, an inductive sensor can output a signal that corresponds to the inductance value of a coil.

[0059] Capacitive sensors may include conductors. The conductors of a capacitive sensor may be connected to an internal space (e.g., ...). Figure 1 or Figure 2 The internal spaces 104 are arranged adjacent to each other. Capacitive sensors can output signals corresponding to the surrounding electromagnetic properties (e.g., the capacitance around a conductor). For example, when an aerosol generating article S with metallic packaging paper is inserted into the insertion space, the packaging paper of the aerosol generating article S changes the electromagnetic properties around the conductor.

[0060] The reusability detection sensor 134 can detect whether the aerosol-generating article S is reused. The reusability detection sensor 134 can be a color sensor. The color sensor can detect the color of the aerosol-generating article S. The color sensor can detect the color of a portion of the packaging paper covering the outer surface of the aerosol-generating article S. The color sensor can detect optical characteristic values ​​corresponding to the object's color based on the light reflected from the object. For example, the optical characteristic can be the wavelength of light. The color sensor can be implemented as a unit integrated with the proximity sensor, or it can be implemented as a separate unit from the proximity sensor.

[0061] At least a portion of the packaging paper constituting the aerosol-generating article S changes color due to the aerosol. The reusable detection sensor 134 can be arranged to correspond to the position of at least a portion of the packaging paper that changes color due to the aerosol when the aerosol-generating article S is inserted into the insertion space. For example, before the user uses the aerosol-generating article S, the color of at least a portion of the packaging paper may be a first color. At this time, when the aerosol generated by the aerosol generating device 1 passes through the aerosol-generating article S, at least a portion of the packaging paper is soaked in the aerosol, thereby changing the color of at least a portion of it to a second color. Simultaneously, after the color of at least a portion of the packaging paper changes from the first color to the second color, it can retain the second color.

[0062] The cartridge (vaporizer) detection sensor 135 can detect the installation and / or removal of the vaporizer 19. The cartridge detection sensor 135 can be implemented as an inductive sensor, a capacitive sensor, a resistive sensor, or a Hall IC utilizing the Hall effect.

[0063] The cap detection sensor 136 can detect the installation and / or removal of the cap. When the cap is separated from the housing 10, the vaporizer 19 covered by the cap and a portion of the housing 10 are exposed to the outside. The cap detection sensor 136 can be implemented as a contact sensor, a Hall sensor (hall IC), an optical sensor, etc.

[0064] The motion detection sensor 137 can detect the motion of the aerosol generating device 1. The motion detection sensor 137 can be implemented as at least one of an accelerometer and a gyroscope.

[0065] In addition to the sensors (131 to 137) described above, sensor 13 may also include one or more of the following: humidity sensor, barometric pressure sensor, magnetic sensor, position sensor (e.g., GPS), and proximity sensor.

The low-pass filter may include at least one inductor and a capacitor. The cutoff frequency of the low-pass filter may correspond to the frequency of the high-frequency switching power supply applied from the power supply 11 to the carburetor heater 191. The low-pass filter can prevent high-frequency noise components from being applied to sensors 13, such as the insertion detection sensor 133.

[0074] In one embodiment, the vaporizer heater 191 can be made of any suitable resistive material.

[0089] The control unit 12 can control the output voltage of the power supply 11 by controlling the switching of the switching elements of the power supply circuit. The power conversion circuit can convert the output voltage of the power supply 11. For example, the power conversion circuit may include a buck converter for reducing the output voltage of the power supply 11. For example, the power conversion circuit can be implemented as a buck-boost converter, a Zener diode, etc.

[0090] The control unit 12 can control the switching operation of the switching elements in the power conversion circuit to adjust the voltage level output from the power conversion circuit. When the switching elements remain in the on state, the voltage level output from the power conversion circuit can correspond to the voltage level output from the power supply 11. The duty cycle of the switching operation can correspond to the ratio of the voltage output from the power conversion circuit to the voltage output from the power supply 11. As the duty cycle of the switching operation decreases, the voltage level output from the power conversion circuit decreases. The carburetor heater 191 can achieve heating based on the voltage output from the power conversion circuit.

[0091] The control unit 12 can use at least one of pulse width modulation (PWM) and proportional-integral-differential (PID) methods to control the power supply to the heater 18.

[0092] For example, the control unit 12 can use PWM to control the supply of current pulses with a predetermined frequency and duty cycle to the carburetor heater 191. The control unit 12 can control the power supplied to the carburetor heater 191 by adjusting the frequency and duty cycle of the current pulses.

[0093] For example, the control unit 12 can determine the target temperature as the control objective based on the temperature curve. The control unit 12 uses a PID method to control the power supplied to the vaporizer heater 191, wherein the PID method is a feedback control method based on the difference between the temperature of the vaporizer heater 191 and the target temperature, the integral value of the difference over time, and the derivative value of the difference over time.

[0094] The control unit 12 can prevent the vaporizer heater 191 from overheating. For example, the control unit 12 can control the operation of the power conversion circuit to stop supplying power to the vaporizer heater 191 when the temperature of the vaporizer heater 191 exceeds a preset limit temperature. For example, the control unit 12 can reduce the power supplied to the vaporizer heater 191 by a predetermined percentage when the temperature of the vaporizer heater 191 exceeds the preset limit temperature. For example, the control unit 12 can determine that the aerosol generating material in the vaporizer heater 191 has been depleted when the temperature of the vaporizer heater 191 exceeds the preset limit temperature, and cut off the power supply to the vaporizer heater 191.

[0095] The control unit 12 can control the charging and discharging of the power supply 11. The control unit 12 can determine the temperature of the power supply 11 based on the output signal of the temperature sensor 131.

[0096] When the power cord is connected to the battery terminal of the aerosol generating device 1, the control unit 12 can confirm whether the temperature of the power supply 11 is above a first limit temperature, which serves as the standard for cutting off charging of the power supply 11. When the temperature of the power supply 11 is below the first limit temperature, the control unit 12 can control the charging of the power supply 11 based on a preset charging current. When the temperature of the power supply 11 is above the first limit temperature, the control unit 12 can cut off the charging of the power supply 11.

[0097] When the aerosol generating device 1 is powered on, the control unit 12 can check whether the temperature of the power supply 11 is above a second limit temperature, which is the standard for cutting off the discharge of the power supply 11. When the temperature of the power supply 11 is below the second limit temperature, the control unit 12 can control the use of the power stored in the power supply 11. When the temperature of the power supply 11 is above the second limit temperature, the control unit 12 can cut off the use of the power stored in the power supply 11.

[0098] 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 sensing values ​​of the power supply 11.

[0099] The control unit 12 can determine whether the aerosol generating article S has been inserted into the insertion space by the insertion detection sensor 133. The control unit 12 can determine that the aerosol generating article S has been inserted based on the output signal of the insertion detection sensor 133. When it is determined that the aerosol generating article S has been inserted into the insertion space, the control unit 12 can control the power supply to the vaporizer heater 191. For example, the control unit 12 can supply power to the vaporizer heater 191 based on the temperature profile stored in the memory 17.

[0100] The control unit 12 can determine whether the aerosol generating article S has been removed from the insertion space. For example, the control unit 12 can determine whether the aerosol generating article S has been removed from the internal space by using the insertion detection sensor 133. For example, when the temperature of the heater 18 is above a limit temperature or when the temperature change slope of the heater 18 is above a set slope, the control unit 12 can determine that the aerosol generating article S has been removed from the internal space. When it is determined that the aerosol generating article S has been removed from the internal space, the control unit 12 can cut off the power supply to the vaporizer heater 191.

[0101] The control unit 12 can control the power supply time and / or power supply amount to the vaporizer heater 191 based on the state of the aerosol-generating article S detected by the sensor 13. The control unit 12 can confirm the signal level range of the capacitive sensor based on a lookup table. The control unit 12 can determine the moisture content of the aerosol-generating article S based on the confirmed signal level range.

[0102] When the aerosol generating article S is in an over-humid state, the control unit 12 can control the power supply time to the vaporizer heater 191, thereby increasing the preheating time of the aerosol generating article S compared to the normal state.

[0103] The control unit 12 can determine whether the aerosol generating article S inserted into the insertion space is reused by the reuse detection sensor 134. For example, the control unit 12 can compare the sensed value of the signal from the reuse detection sensor with a first reference range including the first color, and determine that the aerosol generating article S has not been used when the sensed value is within the first reference range. For example, the control unit 12 can compare the sensed value of the signal from the reuse detection sensor with a second reference range including the second color, and determine that the aerosol generating article S has been used when the sensed value is within the second reference range. When it is determined that the aerosol generating article S has been used, the control unit 12 can cut off the power supply to the vaporizer heater 191.

[0104] The control unit 12 can determine whether the vaporizer 19 is engaged and / or removed by the cartridge detection sensor 135. For example, the control unit 12 can determine whether the vaporizer 19 is engaged and / or removed based on the sensing value of the signal from the cartridge detection sensor.

[0105] The control unit 12 can determine whether the aerosol-generating material in the vaporizer 19 has been depleted. For example, the control unit 12 can preheat the vaporizer heater 191 using a power supply and determine whether the temperature of the vaporizer heater 191 exceeds a limit temperature during preheating. When the temperature of the vaporizer heater 191 exceeds the limit temperature, it can be determined that the aerosol-generating material in the vaporizer 19 has been depleted. When it is determined that the aerosol-generating material in the vaporizer 19 has been depleted, the control unit 12 can cut off the power supply to the vaporizer heater 191.

[0106] The control unit 12 can determine whether the vaporizer 19 can be used. For example, the control unit 12 can determine that the vaporizer 19 cannot be used based on data stored in the memory 17 if the current number of suctions is greater than the set maximum number of suctions for the vaporizer 19. For example, when the total heating time of the heater 24 is greater than or equal to the set maximum time or the total power supplied to the heater 24 is greater than or equal to the preset maximum power, the control unit 12 can determine that the vaporizer 19 cannot be used.

[0107] The control unit 12 can determine the user's inhalation through the suction sensor 132. For example, the control unit 12 can determine whether suction has occurred based on the sensed value of the signal from the suction sensor 132. For example, the control unit 12 can determine the suction intensity based on the sensed value of the signal from the suction sensor 132. When the number of suctions reaches the preset maximum number of suctions or when no suction is detected for more than a preset time, the control unit 12 can cut off the power supply to the vaporizer heater 191.

[0108] The control unit 12 can determine whether the lid is engaged and / or removed by the lid detection sensor 136. For example, the control unit 12 can determine whether the lid is engaged or removed based on the sensed value of the signal from the lid detection sensor.

[0109] The control unit 12 can control the output unit 14 based on the detection results of the sensor 13. For example, when the number of suctions counted by the suction sensor 132 reaches a preset number, the control unit 12 can notify the user that the aerosol generating device 1 is about to shut down through one or more output signals from the display 141, the tactile unit 142, and the sound output unit 143. For example, the control unit 12 can notify the user through the output unit 14 based on the determination that there is no aerosol generating item S in the internal space. For example, the control unit 12 can notify the user through the output unit 14 based on the determination that the vaporizer 19 and / or the cover are not installed. For example, the control unit 12 can notify the user of the temperature information of the vaporizer heater 191 through the output unit 14.

[0110] The control unit 12 can store and update the historical records of events that occur in the memory 17 based on the occurrence of predetermined events. Events may include events performed in the aerosol generating device 1, such as insertion detection of the aerosol generating article S, initiation of heating the aerosol generating article S, suction detection, suction termination, overheat detection of the vaporizer heater 191, overvoltage detection applied to the vaporizer heater 191, termination of heating the aerosol generating article S, power-on / off operation of the aerosol generating device 1, charging initiation of the power supply 11, overcharge detection of the power supply 11, and charging termination of the power supply 11. The historical records of events may include the date and time of the event, log data corresponding to the event, etc. For example, when the predetermined event is the insertion detection of the aerosol generating article S, the log data corresponding to this event may include data such as the sensing value of the insertion detection sensor 133. For example, when the predetermined event is the overheat detection of the vaporizer heater 191, the log data corresponding to the event may include the temperature of the vaporizer heater 191, the voltage applied to the vaporizer heater 191, the current flowing through the vaporizer heater 191, etc.

[0111] The control unit 12 can control the establishment of a communication link with an external device (such as a user's mobile terminal). When authentication-related data is received from the external device via the communication link, the control unit 12 can remove the usage restriction on at least one function of the aerosol generating device 1. The authentication data may include data indicating that user authentication for the user corresponding to the external device has been completed. The user can authenticate themselves through the external device. The external device can determine the validity of user data based on the user's birthday, a unique identifier, etc., and receive usage permission data for the aerosol generating device 1 from an external server. The external device can send data indicating that user authentication has been completed to the aerosol generating device 1 based on the usage permission data. When user authentication is completed, the control unit 12 can remove the usage restriction on at least one function of the aerosol generating device 1. For example, when user authentication is completed, the control unit 12 can remove the usage restriction on the heating function that supplies power to the vaporizer heater 191.

[0112] The control unit 12 can send status data about the aerosol generating device 1 to the external device via a communication link. The external device can then output information such as the remaining capacity of the power supply 11 and the operating mode of the aerosol generating device 1 through its display based on the received status data.

[0113] An external device can send a location search request to the aerosol generating device 1 based on an input indicating that a location search has been initiated. When a location search request is received from the external device, the control unit 12 can control one or more output devices to perform operations corresponding to the location search based on the received location search request. For example, the haptic unit 142 can generate vibration in response to the location search request. For example, the display 141 can output an object corresponding to the search position and the end of the search in response to the location search request.

[0114] The control unit 12 can control the execution of firmware updates when it receives firmware data from an external device. The external device can verify the current version of the firmware of the aerosol generating device 1 and determine whether a new firmware version exists. When the external device receives a firmware download request, it can receive the new version firmware data and send it to the aerosol generating device 1. When the control unit 12 receives the new version firmware data, it can control the execution of firmware updates for the aerosol generating device 1.

[0115] The control unit 12 transmits the sensing data of at least one sensor 13 to an external server (not shown) via the communication unit 16, and learns the sensing values ​​from the server using machine learning such as deep learning, and receives and stores the generated learning model. The control unit 12 can use the learning model received from the server to perform tasks such as determining the user's suction mode and generating a temperature curve. The control unit 12 can store the sensing data of at least one sensor 13 and data for learning an artificial neural network (ANN) in a memory 17. For example, the memory 17 can store a database of the various structures of the aerosol generating device 1, as well as the weights and biases constituting the ANN structure, for learning the artificial neural network (ANN). The control unit 12 generates at least one learning model for determining the user's suction mode, generating a temperature curve, etc., by learning the sensing data of at least one sensor 13, the user's suction mode, the temperature curve, etc., stored in the memory 17.

[0116] refer to Figure 4 According to one embodiment, the aerosol generating article S may include a first filter section S1, a medium section S2, a second filter section S3, and packaging paper S5.

[0117] In one embodiment, the aerosol generating article S can be packaged using at least one packaging paper S5. At least one hole may be formed in the packaging paper S5 to allow external air to be introduced or internal gas to be exhausted to the outside. The packaging paper S5 may comprise a material with high thermal conductivity.

[0118] For example, the first filter section S1 can be packaged with the first packaging paper S51, the medium section S2 can be packaged with the second packaging paper S52, and the second filter section S3 can be packaged with the third packaging paper S53. Furthermore, the entire aerosol generating article S can be packaged with the fifth packaging paper S55.

[0119] In one embodiment, the first wrapping paper S51, the second wrapping paper S52, and the third wrapping paper S53 can be made of porous cigarette paper. For example, the porosity of each of the first wrapping paper S51, the second wrapping paper S52, and the third wrapping paper S53 can be 35000 CU, but is not limited thereto. Furthermore, the thickness of each of the first wrapping paper S51, the second wrapping paper S52, and the third wrapping paper S53 can be in the range of 70 μm to 80 μm. Additionally, the basis weight of each of the first wrapping paper S51, the second wrapping paper S52, and the third wrapping paper S53 can be 20 g / m³. 2 Up to 25g / m 2 Within the range.

[0120] In one embodiment, the fifth wrapping paper S55 can be made of aseptic paper (MFW). For example, the basis weight of the fifth wrapping paper S55 can be 57 g / m³. 2 Up to 63g / m 2 Within a certain range. Furthermore, the thickness of the fifth packaging paper S55 can range from 64 μm to 70 μm.

[0121] In one embodiment, the first filter section S1 may be composed of a cellulose acetate filter tip. Alternatively, the first filter section S1 may be composed of a paper filter tip and a porous molded part, etc. For example, the length of the first filter section S1 may be from 4 mm to 15 mm, but is not limited thereto. In addition, the first filter section S1 may be colored or scented.

[0122] In one embodiment, the media segment S2 may be filled with a medium. For example, the media segment S2 may include a cavity, and the cavity may be filled with a medium. As another example, the media segment S2 may include a cellulose acetate filter or a paper filter, and a filling medium may be inserted into the cellulose acetate filter or the paper filter.

[0123] For example, the medium substrate filling the medium segment S2 may include at least one component selected from granular tobacco (tobacco pellets), reconstituted tobacco, and tobacco shreds. For example, the length of the medium segment S2 may be an appropriate length in the range of 6 mm to 18 mm, but is not limited thereto.

[0124] Generally, the moisture and / or aerosol forming agent content of tobacco particles is significantly lower than that of other types of tobacco materials (such as shredded tobacco, reconstituted tobacco, etc.), thus greatly reducing the generation of visible smoke and facilitating the smokeless function of the aerosol generating device 1. However, the diameter, density, filling rate, material composition ratio, heating temperature, etc., of the tobacco particles can vary depending on the implementation method. The diameter of the tobacco particles can be approximately 0.3 mm to 1.2 mm. Within this range, appropriate hardness and processability of the tobacco particles can be ensured, and the probability of generating eddies within the chamber can be increased.

[0125] In addition, the medium segment S2 may also include other additives, such as flavoring agents, humectants, and / or organic acids. Furthermore, the medium segment S2 may include flavoring liquids, such as menthol or humectants, which are added by spraying them onto the medium segment S2.

[0126] In one embodiment, the medium segment S2 may include a pH-treated medium. For example, the medium substrate may be pH-treated with a pH adjuster to be alkaline, and the pH adjuster may be alkaline, for example, including at least one material selected from potassium carbonate (K2CO3), sodium bicarbonate (NaHCO3), and calcium oxide (CaO). However, the materials included in the pH adjuster are not limited to the above examples, and materials that produce less unpleasant odors during smoking may also be used. The alkaline pH adjuster can increase the pH value of the medium substrate included in the medium segment S2. Compared with a medium substrate that has not been treated with an alkaline pH adjuster, the alkaline pH-treated medium substrate can increase nicotine emissions. That is, the alkaline pH-treated medium substrate can obtain sufficient nicotine yield from the medium segment S2 even at low temperatures.

[0127] In one embodiment, the media segment S2 may include a pulp or paper sheet with a pH value adjusted to 7.0 to 9.5, or may include tobacco particles with a pH value adjusted to 7.0 to 9.5. The media substrate may include nicotine and is treated with an alkaline pH to enable the migration of free nicotine (gaseous nicotine) from the media substrate, even under non-heating conditions or relatively low temperature conditions. That is, by adjusting the pH value of the media substrate of the media segment S2 to the range of 7.0 to 9.5, volatile free nicotine can migrate under non-heating conditions (or low-temperature heating conditions) and achieve a sufficient level of tobacco flavor intensity.

[0128] In one embodiment, the second filter segment S3 may be made of a cellulose acetate filter. Additionally, the second filter segment S3 may include at least one flavor capsule. For example, the second filter segment S3 may be a cellulose acetate filter in which at least one flavor capsule is inserted. Furthermore, the second filter segment S3 may be made of a cellulose acetate filter infused with flavoring material.

[0129] In one embodiment, nicotine can be adsorbed into at least one of the first filter section S1 and the second filter section S3. Since the pH value of the medium section S2 is in the range of 7.0 to 9.5, the nicotine in the medium section S2 exists in an active free nicotine state even under non-heating conditions and can migrate to the first filter section S1 or the second filter section S3. Therefore, the nicotine migrating from the medium section S2 can be adsorbed into one or more of the first filter section S1 and the second filter section S3. Since not only the medium section S2 contains nicotine, but also the first filter section S1 or the second filter section S3 contains nicotine, the aerosol-generating article S can be used even without preheating the aerosol generating device 11. This not only improves user convenience but also achieves sufficient nicotine delivery even under non-heating (or low-temperature heating) conditions, thereby providing the satisfaction of a tobacco flavor.

[0130] Figure 5 An exploded perspective view of the outer shell portion 10-1 that constitutes the internal space 104 of the outer shell 10 is shown.

[0131] refer to Figure 5 The first sensor 13-1 and the second sensor 13-2 can be along the length direction of the internal space 104 (e.g.: Figure 5 Arrangement in the + / -X direction.

[0132] In one embodiment, the first sensor 13-1 and the second sensor 13-2 may be along a direction from the first surface 101 toward the end surface 1042 of the internal space (e.g.: Figure 5 Arranged sequentially in the -X direction.

[0133] At least a portion of the first sensor 13-1 may be arranged facing the interior space 104 to detect the state of the aerosol-generating article S inserted into the interior space 104; at least a portion of the second sensor 13-2 may be arranged facing the interior space 104 to detect the state of the aerosol-generating article S inserted into the interior space 104. For example, at least a portion of the first sensor 13-1 and / or the second sensor 13-2 may be exposed from the side 1043 of the interior space. Alternatively, the first sensor 13-1 and / or the second sensor 13-2 may be housed inside the housing portion 10-1 to detect the state of the aerosol-generating article S without being exposed to the interior space 104. Yet another example, at least a portion of the first sensor 13-1 may be arranged in a position exposed from the side 1043 of the interior space, and at least a portion of the second sensor 13-2 may be arranged in a position exposed from the end face 1042 of the interior space.

[0134] In one embodiment, the first sensor 13-1 may be composed of a first capacitive sensor, and the second sensor 13-2 may be composed of a second capacitive sensor. The first and / or second capacitive sensors may include a conductor. This conductor may be arranged adjacent to the internal space side 1043. The first and / or second capacitive sensors may output a signal corresponding to the capacitance of an adjacent segment (section) of the aerosol-generating article S. For example, if the moisture content of each segment of the aerosol-generating article S is different, the electromagnetic properties around the conductor will change accordingly, and the first and second capacitive sensors may represent the capacitance corresponding to each segment, respectively.

[0135] In one embodiment, the first sensor 13-1 may be composed of a first inductive sensor, and the second sensor 13-2 may be composed of a second inductive sensor. The first and / or second inductive sensors may include at least one coil. The coil may be arranged adjacent to the internal space side 1043. For example, if the magnetic field around the coil through which current flows changes, the characteristics of the current flowing through the coil may change according to Faraday's law of electromagnetic induction. The first and / or second inductive sensors may output a signal corresponding to the characteristics of the current flowing through the coil. For example, if the water content of different segments of the aerosol-generating article S is different, the first and second inductive sensors may represent signal values ​​corresponding to each segment.

[0136] The signals measured by the first sensor 13-1 and / or the second sensor 13-2 can be transmitted to the control unit via connector 13-3 (e.g.: Figure 1 or Figure 2 Control unit 12).

[0137] Figure 6 The aerosol-generating article S is shown inserted. Figure 5 The state of the internal space 104 of the outer shell portion 10-1.

[0138] refer to Figure 6 In one embodiment, when the aerosol-generating article S is fully inserted into the internal space 104, the first sensor 13-1 may be located at a position corresponding to the medium segment S2 of the aerosol-generating article S. For example, the first sensor 13-1 may be arranged in a horizontal direction (e.g., along) the medium segment S2. Figure 6 The positions separated on the YZ plane.

[0139] When the aerosol generating article S is fully inserted into the internal space 104, the second sensor 13-2 can be positioned corresponding to the first filter section S1 of the aerosol generating article S. For example, the second sensor 13-2 can be positioned horizontally relative to the first filter section S1 (e.g., along...). Figure 6 The positions separated on the YZ plane.

[0140] When the first sensor 13-1 is composed of a first capacitive sensor and the second sensor 13-2 is composed of a second capacitive sensor, the first sensor 13-1 can detect the degree of wetness (over-wetness) of the medium section S2, and the second sensor 13-2 can detect the degree of wetness (over-wetness) of the first filter section S1.

[0141] In one embodiment, when both the first sensor 13-1 and the second sensor 13-2 are composed of capacitive sensors, the area of ​​the side of the first sensor 13-1 facing the internal space 1043 and the area of ​​the side of the second sensor 13-2 facing the internal space 1043 can be the same. By making the exposed area of ​​the first sensor 13-1 (e.g., the area of ​​the side of the first sensor 13-1 facing the internal space 1043) and the exposed area of ​​the second sensor 13-2 (e.g., the area of ​​the side of the second sensor 13-2 facing the internal space 1043) the same, interference between the two sensors can be minimized.

[0142] In order to minimize the influence between the first sensor 13-1 and the second sensor 13-2, the first sensor 13-1 can be arranged adjacent to the first surface 101, and the second sensor 13-2 can be arranged adjacent to the end surface 1042 of the internal space. For example, considering the determined size of the aerosol generating device 1, the spacing between the first sensor 13-1 and the second sensor 13-2 can be maximized. For example, the second sensor 13-2 can be arranged at the innermost side of the internal space 104. Similarly, the first sensor 13-1 can be arranged at the position closest to the first surface 101, and due to the proximity sensor configuration, the first sensor 13-1 can be arranged below the proximity sensor from the first surface 101.

[0143] In one embodiment, when the first sensor 13-1 is composed of a first capacitive sensor and the second sensor 13-2 is composed of a second capacitive sensor, if the absolute value of the difference between the first capacitance change measured by the first capacitive sensor and the second capacitance change measured by the second capacitive sensor is greater than or equal to a first set value between the first time point (before the aerosol generating article S is inserted into the internal space 104) and the second time point (after the aerosol generating article S is inserted into the internal space 104), the control unit 12 can determine that the aerosol generating article S is reused.

[0144] For example, from the vaporizer (e.g.: Figure 1 or Figure 2 The aerosol generated by the vaporizer 19 can enter the first filtration section S1 of the aerosol generating article S, and move to the second filtration section S3 via the medium section S2. When the aerosol moves downstream of the aerosol generating article S (e.g.: Figure 6 When the aerosol-generating article S moves in the +X direction, the downstream side of the aerosol-generating article S becomes more wetted by the aerosol than the upstream side. Since the dielectric constant of the aerosol-generating article S changes as the degree of wetting changes, the first capacitance measured by the first sensor 13-1 and the second capacitance measured by the second sensor 13-2 will differ.

[0145] After using the aerosol-generated article S, the aerosol usually wets the upstream of the aerosol-generated article S more, so the second capacitance measured by the second sensor 13-2 may be greater than the first capacitance measured by the first sensor 13-1.

[0146] Alternatively, depending on the composition of the aerosol-generating article S, the first capacitance measured by the first sensor 13-1 may be greater than the second capacitance measured by the second sensor 13-2. For example, when the medium segment S2 includes a cavity, both the inside and outside of the second packaging paper S52 of the medium segment S2 will be wetted by aerosol, so the medium segment 122 will be more wetted than the first filter segment S1.

[0147] In either case, there is a difference between the first capacitance and the second capacitance at the second time point, or there is a difference between the change in the first capacitance and the change in the second capacitance between the first time point and the second time point.

[0148] At this time, the control unit 12 can determine whether the aerosol generating article S is reused based on the difference between the first change in electrostatic capacitance and the second change in electrostatic capacitance.

[0149] For example, if the absolute value of the difference between the first capacitance change and the second capacitance change is greater than or equal to a first set range (|first capacitance change) If the second change in electrostatic capacitance is ≥ a, where a is the first set value, then the control unit 12 can determine that the aerosol generating article S has been reused. The first set value can be defined as a value that takes into account errors.

[0150] At this point, the reliability of the determination of whether the aerosol-generating article S is reused can be determined based on the magnitude of the absolute value of the difference. For example, the larger the absolute value of the difference, the more accurate the determination of whether the aerosol-generating article S is reused. Therefore, the control unit 12 can define the reuse determination result when the absolute value of the difference is large as having high reliability.

[0151] In one embodiment, when the first sensor 13-1 is composed of a first capacitive sensor and the second sensor 13-2 is composed of a second capacitive sensor, if the absolute value of the difference between the first capacitance change measured by the first sensor 13-1 and the second capacitance change measured by the second sensor 13-2 is less than a second set value between the first time point (before the aerosol generating article S is inserted into the internal space 104) and the second time point (after the aerosol generating article S is inserted into the internal space 104), it can be determined that the aerosol generating article is in an over-humidified state.

[0152] For example, in an environment with high humidity such as the rainy season, the aerosol generating article S may be in an over-wet state. In this over-wet state, the first filter section S1, the medium section S2, and the second filter section S3 of the aerosol generating article S will all be wetted, thereby showing capacitance values that converge to the corresponding humidity.

[0153] At this time, the control unit 12 can determine whether the aerosol generating article S is in an over-wet state based on the difference between the first capacitance change amount and the second capacitance change amount. Alternatively, the control unit 12 can determine whether the aerosol generating article S is in an over-wet state based on the difference between the first capacitance and the second capacitance at the second time point.

[0154] For example, if the absolute value of the difference between the first capacitance change amount and the first capacitance change amount between the first time point and the second time point is less than the second set value (|first capacitance change amount - second capacitance change amount| < b, where b is the second set value), then the control unit 12 can determine that the aerosol generating article S is in an over-wet state. Among them, the second set value can be defined as the set value after considering errors.

[0155] Another example, if the absolute value of the difference between the first capacitance and the second capacitance at the second time point is less than the fourth set value (|first capacitance - second capacitance| at the second time point < d, where d is the fourth set value), then the control unit 12 can determine that the aerosol generating article S is in an over-wet state.

[0156] When only one capacitance-type sensor is configured, it may not be possible to determine whether the increase in capacitance is due to repeated use or due to over-wet conditions. According to an embodiment, the aerosol generating device 1 is provided with a first sensor 13-1 and a second sensor 13-2. Compared with the case of only arranging one capacitance-type sensor, this can prevent misjudgment of repeated use due to excessive humidity. For example, under over-wet conditions, the first capacitance change amount of the first sensor 13-1 and the second capacitance change amount of the second sensor 13-2 will increase simultaneously. Among them, since the capacitances of all capacitance-type sensors increase simultaneously, the difference between the first capacitance and the second capacitance at the same time point is very small, so that the control unit 12 will not recognize this situation as repeated use.

[0157] In one embodiment, when the first sensor 13-1 is a capacitance-type sensor and the second sensor 13-2 is a capacitance-type sensor, if, between a first time point (before the aerosol-generating article S is inserted into the internal space 104) and a second time point (after the aerosol-generating article S is inserted into the internal space 104), one or more of the first capacitance change amount measured by the first sensor 13-1 and the second capacitance change amount measured by the second sensor 13-2 is less than a third set value, it can be determined that the aerosol-generating article S has not been used.

[0158] For example, compared with the case of reuse or excessive moisture, the first capacitance change amount and / or the second capacitance change amount of the unused aerosol-generating article S may be the smallest. At this time, if one or more of the first capacitance change amount and the second capacitance change amount is less than the third set value (the first capacitance change amount < c, or the second capacitance change amount < c, where c is the third set value), the control unit 12 can determine that the aerosol-generating article S has not been used.

[0159] Another example is that in the unused aerosol-generating article S, the capacitance of the medium section S2 may be the highest compared with the first filter section S1 or the second filter section S3. At this time, if the first capacitance is greater than the second capacitance, the control unit 12 can determine that the aerosol-generating article S has not been used.

[0160] In one embodiment, when the first sensor 13-1 is a capacitance-type sensor and the second sensor 13-2 is a capacitance-type sensor, the control unit 12 can verify the type of the aerosol-generating article according to whether the first capacitance measured by the first sensor 13-1 and the second capacitance measured by the second sensor 13-2 exceed a first set range.

[0161] For example, when the aerosol-generating article S is identified as unused, the control unit 12 can further determine whether the aerosol-generating article S is a type suitable for the aerosol-generating device 1 or whether it is a genuine product. The control unit 12 can pre-acquire and store the capacitance value data of the medium section S2 and the capacitance value data of the first filter section S1 of the genuine aerosol-generating article S. The control unit 12 can compare the first capacitance and the second capacitance with the pre-acquired data, and if it exceeds the first set range, it can be determined as a non-genuine product. At this time, the control unit 12 can stop the operation of the aerosol-generating device 1 or issue an alarm for an incorrect insertion of the aerosol-generating article S.

[0162] Figure 7 The exploded perspective view of the housing part 10-1 constituting the internal space 104 of the housing 10 is shown. In the following description of Figure 7 For the sake of brevity, the description of Figure 5Repeating components.

[0163] refer to Figure 7 In one embodiment, when the first sensor 13-1 is composed of a capacitive sensor and the second sensor 13-22 is composed of a capacitive sensor, the area of ​​the second sensor 13-22 facing the internal space side 1043 can be larger than the area of ​​the first sensor 13-1 facing the internal space side 1043.

[0164] Capacitance is inversely proportional to the distance from the space where the dielectric material is placed, but directly proportional to the cross-sectional area of ​​the dielectric material. Therefore, when an aerosol generating article S is inserted into the internal space 104, if the area of ​​the capacitive sensor facing the internal space side 1043 is large, it can hold more charge.

[0165] Since the exposed area of ​​the second sensor 13-22 (e.g., the area of ​​the second sensor 13-22 facing the internal space side 1043) is larger than the exposed area of ​​the first sensor 13-1 (e.g., the area of ​​the first sensor 13-1 facing the internal space side 1043), the degree of wetting of the first filter section S1, which is more moistened by aerosols, can be measured more accurately.

[0166] The width W2 of the second sensor 13-22 along the periphery of the inner space side surface 1043 can be greater than the width W1 of the first sensor 13-1 along the periphery of the inner space side surface 1043. Because the exposed area of ​​the second sensor 13-22 is larger, when a portion of the second sensor 13-22 is close to the first sensor 13-1, the second sensor 13-22 will sense the magnetic field from the dielectric segment S2. In this case, by increasing the width W2 without increasing the width of the second sensor 13-22 along its length (e.g., ... Figure 7 The length of the sensor (in the + / -X direction) can increase the exposed area of ​​the second sensor 13-22. This helps to maximize the spacing between the first sensor 13-1 and the second sensor 13-22.

[0167] Figure 8 and Figure 9 An aerosol generating system 200 according to one embodiment is shown.

[0168] refer to Figure 8 and Figure 9 The aerosol generation system 200 may include an aerosol generation device 2 and an aerosol generation article S. The aerosol generation device 2 may include one or more of a power supply 21, a control unit 22, a sensor 23, a vaporizer 29, and a heater 28. One or more of the power supply 21, control unit 22, sensor 23, and heater 28 may be disposed inside the housing 20 of the aerosol generation device 2. The housing 20 provides a space open to one side for insertion of the aerosol generation article S.

[0169] Heater 28 can heat the aerosol generating article S. Heater 28 can extend upwards in an elongated shape around the space into which the aerosol generating article S is inserted. For example, the interior of heater 28 can include a hollow tubular structure. Heater 28 can be arranged around the interior space. Heater 28 can be arranged to surround at least a portion of the interior space. Heater 28 can heat the interior space or the aerosol generating article S inserted into the interior space. Heater 28 can include a resistance heater and / or an induction heater.

[0170] For example, heater 28 may be a resistance heater. For example, heater 28 may include a conductive track, and heater 28 may be heated when current flows through the conductive track. Heater 28 may be electrically connected to power supply 21. Heater 28 can receive current from power supply 21 and generate heat directly.

[0171] For example, the aerosol generating device 2 may include an induction coil surrounding a heater 28. The induction coil can heat the heater 28. The heater 28, acting as a susceptor, can be heated by the magnetic field generated by the alternating current flowing through the induction coil. The magnetic field can penetrate the heater 28 and generate eddy currents within it. The current can also heat the heater 28.

[0172] Meanwhile, the aerosol generating article S may include a susceptor inside, and the susceptor inside the aerosol generating article S can be heated by the magnetic field generated by the alternating current flowing through the induction coil.

[0173] The vaporizer 29 may contain aerosol-generating substances in any of the following states: liquid, solid, gas, or gel. The aerosol-generating substances may include liquid compositions. For example, the liquid composition may be a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may be a liquid containing non-tobacco substances. The vaporizer 29 may be integrally formed with the housing 20 or detachably attached to the housing 20.

[0174] For example, refer to Figure 8 The vaporizer 29 is integrated with the housing 20 and can be connected to the internal space through the airflow channel CN.

[0175] For example, refer to Figure 9 A space is formed on one side of the outer casing 20, and at least a portion of the vaporizer 29 is inserted into the space formed on one side of the outer casing 20, thereby securing the vaporizer 29 to the outer casing 20. The airflow passage CN may be defined by a portion of the cartridge and / or a portion of the outer casing 20, and the vaporizer 29 may communicate with the internal space through the airflow passage CN.

[0176] The housing 20 can be configured to allow external air to flow into the housing 20 when the carburetor 29 is inserted. At this time, the external air flowing into the housing 20 can pass through the carburetor 29 and flow into the user's mouth.

[0177] The vaporizer 29 may include a storage section C0 for containing aerosol-generating substances and / or a heater 291 for heating the aerosol-generating substances in the storage section C0. A liquid delivery means for wetting (containing) the aerosol-generating substances may be arranged inside the storage section C0. The liquid delivery means may include a core material such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic. The conductive track of the heater 291 may be formed as a coil structure wound around the liquid delivery member or a structure contacting one side of the liquid delivery member. The heater 291 may be referred to as a vaporizer heater 291.

[0178] Vaporizer 29 is capable of generating aerosols. Aerosols are generated when the liquid transport component is heated by vaporizer heater 291. Aerosols can be generated by heating the aerosol-generating article S through vaporizer heater 291. When the aerosol generated by vaporizer heater 291 passes through the aerosol-generating article S, tobacco substances can be incorporated into the aerosol, and the tobacco-infused aerosol is inhaled into the user's mouth through one end of the aerosol-generating article S.

[0179] The aerosol generating device 2 may include a cover (not shown). The cover is detachably attached to the housing 20 to cover at least a portion of the vaporizer 29 connected to the housing 20. The aerosol generating article S can penetrate the cover to be inserted into the housing 20.

The control unit 22 can control the operation of the display, motor, etc., installed in the aerosol generating device 2. The control unit 22 can check the status of each component of the aerosol generating device 2 to determine whether the aerosol generating device is in an operational state.

[0182] The control unit 22 can analyze the detection results of the sensor 23 and control the subsequent processing. For example, the control unit 22 can control the power supplied to the vaporizer heater 291 and / or heater 28 based on the results detected by the sensor 23, thereby starting and stopping the vaporizer heater 291 and / or heater 28. For example, the control unit 22 can control the power supplied to the vaporizer heater 291 and the power supply time based on the detection results of the sensor 23, so that the vaporizer heater 291 is heated to a predetermined temperature or maintained at an appropriate temperature.

[0183] Sensor 23 may include one or more of the following: a temperature sensor, a puff sensor, an insertion detection sensor, a color sensor, a cartridge detection sensor, and a cap detection sensor. For example, sensor 23 may detect one or more of the following: the temperature of the vaporizer heater 291 and / or heater 28, the temperature of the power supply 21, and the internal and external temperatures of the housing 20. For example, sensor 23 may sense the user's puff. For example, sensor 23 may sense whether the aerosol generating article S has been inserted into the internal space. For example, sensor 23 may sense whether the vaporizer 29 has been installed. For example, sensor 23 may sense whether the cap has been installed.

[0184] The first sensor 23-1 and the second sensor 23-2 can be along the length direction of the internal space (e.g., along...). Figure 8 and Figure 9 Arrangement in the -X direction.

[0185] The control unit 22 receives first information measured by the first sensor 23-1 and second information measured by the second sensor 23-2, and determines the state of the aerosol-generating article S based on the first and second information. Since the functions of the first sensor 23-1 and the second sensor 23-2 are the same as or similar to the functions of the first sensor 13-1 and the second sensor 13-2, detailed descriptions will be omitted for the sake of brevity.

For example, heater 38 may include a conductive track, and heater 38 can be heated when current flows through the conductive track. Heater 38 can be electrically connected to power supply 31. Heater 38 can receive current from power supply 31 and generate heat directly. Heater 38 can be a hollow heater arranged around at least a portion of the aerosol generating article S inserted in the insertion space to heat the exterior of the inserted aerosol generating article S, or a heater in the shape of a needle, rod, tube, etc., inserted into the interior of the aerosol generating article S inserted in the insertion space to heat the interior.

[0190] For example, refer to Figure 11 The aerosol generating apparatus may include an induction coil 381 surrounding a heater 38. The induction coil causes the heater 38 to heat up. The heater 38, acting as a susceptor, can heat up based on the magnetic field generated by the alternating current flowing through the induction coil 381. The magnetic field can penetrate the heater 38 and generate eddy currents within it. The current can then cause the heater 38 to heat up.

[0191] On the other hand, the aerosol generating article S may include a susceptor inside, and the susceptor inside the aerosol generating article S can be heated by the magnetic field generated by the alternating current flowing through the induction coil 381.

The control unit 32 can check the status of each component of the aerosol generating device to determine whether the aerosol generating device is in an operational state.

[0194] The control unit 32 can analyze the detection results of the sensor 33 and control the subsequent processing. For example, the control unit 32 can control the power supplied to the heater 38 based on the detection results of the sensor 33, thereby starting and stopping the heater 38. For example, the control unit 32 can control the power supplied to the heater 38 and the power supply time based on the detection results of the sensor 33, so that the heater 38 is heated to a predetermined temperature or maintained at an appropriate temperature.

[0195] Sensor 33 may include one or more of a temperature sensor, a puff sensor, an insertion detection sensor, a color sensor, a cartridge detection sensor, and a cap detection sensor. For example, sensor 33 may detect one or more of the temperature of heater 38, the temperature of power supply 31, and the internal and external temperatures of housing 30. For example, sensor 33 may sense a user's puff. For example, sensor 33 may sense whether the aerosol-generating item S has been inserted into the insertion space.

[0196] The first sensor 33-1 and the second sensor 33-2 can be along the length direction of the internal space (e.g., along...). Figure 10 or Figure 11 Arrangement in the -X direction.

[0197] The control unit 32 receives first information measured by the first sensor 33-1 and second information measured by the second sensor 33-2, and determines the state of the aerosol-generating article S based on the first and second information. Since the functions of the first sensor 33-1 and the second sensor 33-2 are the same as or similar to the functions of the first sensor 13-1 and the second sensor 13-2, detailed descriptions will be omitted for the sake of brevity.

When the first filtration section is composed of an atomizing section, the aerosol generating device 3 may not have a separate vaporizer; instead, a heater 38 may be provided around and / or inside the first filtration section composed of the atomizing section.

[0199] According to one embodiment, the aerosol generating apparatuses 1, 2, and 3, and the aerosol generating systems 100, 200, and 300 including them, can effectively determine whether the aerosol-generating article S is reused.
