[0002] Recently, there has been a growing demand for alternatives to overcome the shortcomings of traditional cigarettes. For example, there is a growing need for devices that generate aerosols by electrically heating a cigarette stick (e.g., cigarette-type electronic cigarettes). Research on cigarette sticks (or aerosol-generating articles) and electrically heated aerosol-generating devices inserted into cigarette sticks has also become active.

[0003] For example, aerosol generating devices can generate aerosols by atomizing aerosol generating substances contained in aerosol generating articles (such as sticks, cigarettes, or cartridges).

[0004] The aerosol generating device can acquire information related to the inserted aerosol generating article and control the drive of heaters, etc., to generate aerosols based on this information. For example, the aerosol generating device can control the drive state of the heater based on information related to the inserted cigarette stick, thereby providing a temperature profile suitable for each individual cigarette stick.

[0005] The background technology described above was acquired or obtained by the inventors during the development of this invention and should not be construed as necessarily being a generally known technology disclosed before the application for this invention. Summary of the Invention

[0035] Figure 1 This is a block diagram of an aerosol generating apparatus 1 according to one embodiment.

[0036] According to one embodiment, the aerosol generating device 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 device 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.

[0037] 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 the immersion of the aerosol generating device 1 in water.

[0038] 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.

[0039] 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, 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, 24 based on the signal corresponding to the resistance value.

[0040] 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 signal corresponding to the resistance value.

[0041] 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 device 1 may include a power protection circuit (PCM), and the temperature sensor can be arranged together with the power protection circuit in a position adjacent to the power supply 11.

[0042] 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).

[0043] According to one embodiment, the suction sensor can sense the user's suction.

[0044] 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 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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 can be configured around the periphery of the insertion space. Furthermore, the insertion sensing sensor can also include any combination of the examples described above.

[0050] 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. When an aerosol-generating article is inserted into or removed from the insertion space, the dielectric constant around the conductor may change. 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.

[0051] As another example, the insertion sensing sensor may include an inductive sensor. The inductive sensor may include at least one coil, which may be positioned adjacent to the insertion space. When the aerosol-generating article (e.g., a wrapper for the aerosol-generating article) includes a conductor, a change in the magnetic field around the coil through which current flows may occur 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, a susceptor (SUS) may be included in the aerosol-generating article (e.g., the dielectric portion of the aerosol-generating article). Even in this case, a change in the magnetic field around the coil may occur based on the insertion or removal of the susceptor in the insertion space, and the control unit 12 may sense the insertion and / or removal of the aerosol-generating article based on the current characteristics of the inductive sensor.

[0052] 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.

[0053] 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 packaging surrounding 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 packaging based on the light reflected from the packaging. If a color change is detected in a portion of the packaging, the control unit 12 can determine that the aerosol-generating article inserted in the insertion space has been used.

[0054] 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 disposed 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 related to the aerosol-generating article based on the confirmed level range.

[0055] 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.

[0056] 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 of an aerosol-generating article (e.g., packaging). 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 contain 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.

[0057] 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.

[0058] As another example, the 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.

[0059] 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.

[0060] 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.

[0061] 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 the cartridge to which the aerosol generating device 1 is mounted or inserted, or covers at least a portion of the housing of the aerosol generating device 1. If the cap is mounted on 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.

[0062] According to one embodiment, a motion sensing sensor can sense 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.

[0063] 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.

[0064] According to one embodiment, the output unit 14 can output status-related information 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 related to the aerosol generating device 1 may include the charging / discharging status of the power supply 11 of the aerosol generating device 1, 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 cap, or a status where the use of the aerosol generating device 1 is restricted (e.g., abnormal article detected). The display can provide the user with status-related information of the aerosol generating device 1 visually. 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 provide the user with status-related information of the aerosol generating device 1 tactilely. For example, the tactile part may include a vibration motor, a piezoelectric element, an electrical stimulation device, etc. The audio output part can provide the user with information related to the aerosol generating device 1 in an auditory manner. For example, the audio output part can convert electrical signals into audio signals and output the audio signals to the outside.

[0065] 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 disposed 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.

[0066] 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).

[0067] According to one embodiment, heaters 18 and 24 can be resistance heaters. For example, the resistance heater can contain a resistive material, including metals or metal alloys such as titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, and nichrome. The resistance heater can be implemented using a metal heating wire, a metal heating plate with conductive tracks, or a ceramic heating element.

[0068] According to one embodiment, heaters 18 and 24 can be induction heating heaters. For example, an induction heating heater may include a susceptor that heats through 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 susceptor. Based on the generation of eddy currents, the susceptor can be heated. According to one embodiment, the susceptor may also be included inside an aerosol generating article (e.g., a medium section). In this case, the susceptor included inside the aerosol generating article can also be heated by an induction coil.

[0069] Heaters 18 and 24 are not limited to the examples above, and may include, or be replaced by, various heating methods, structures, components, etc. for heating aerosol generating articles and / or smoke cartridges.

[0070] According to one embodiment, the input unit 15 can receive information input by a user. For example, the input unit 15 may include a touch panel, a button, a key pad, a dome switch, a jog wheel, a jog switch, etc.

For example, the memory 17 may include at least one type of storage medium selected from flash memory, hard disk, multimedia card microtype, card-type memory (e.g., SD (Secure Digital) or XD (Extreme Digital) memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic storage, magnetic disk, and optical disk. For example, the memory 17 may store data such as the operating time of the aerosol generating apparatus 1, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data related to the user's smoking pattern.

[0072] According to one embodiment, the communication unit 16 may include at least one component for communicating with other electronic devices (e.g., portable electronic devices). For example, the communication unit 16 may include a Bluetooth communication unit, a Bluetooth Low Energy (BLE) communication unit, a Near Field Communication unit, a Wireless Local Area Network (WLAN) communication unit, a Zigbee communication unit, an Infrared Data Association (IrDA) communication unit, a Wi-Fi Direct (WFD) communication unit, an Ultra Wideband (UWB) communication unit, an Ant+ (Adaptive Network Topology) communication unit, a Cellular Network communication unit, an Internet communication unit, a Computer Network (e.g., a Local Area Network (LAN) or a Wide Area Network (WAN)) communication unit, etc.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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 also determine that the aerosol-generating article has been removed from the insertion space.

[0084] 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.

[0085] 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.

[0086] 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 combined 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 power supply to the heaters 18 and 24 to be interrupted or not to be supplied with power to the heaters 18 and 24.

[0087] 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.

[0088] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on whether the cartridge can be used. For example, if the control unit 12 determines that the current number of puffs exceeds the maximum number of puffs set in the cartridge based on data stored in the memory 17, it can determine that the cartridge cannot be used. Alternatively, if the total heating time of the heaters 18 and 24 exceeds the preset maximum time or the total electrical power supplied to the heaters 18 and 24 exceeds the preset maximum electrical power, the control unit 12 can determine that the cartridge cannot be used. 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.

[0089] 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 has been detected for a preset time, the control unit 12 can cut off the power supply to the heaters 18 and 24. When suction is sensed, the control unit 12 can also control the power supply to the heaters 18 and 24.

[0090] 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).

[0091] 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 temperature-related information of the heaters 18 and 24 in a visual, tactile, and / or audible manner.

[0092] According to one embodiment, the control unit 12 can store and update the event-related history in the memory 17 based on the occurrence of a predetermined event. For example, the event 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 event history 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 related to the sensing value of the insertion sensing sensor (e.g., sensor unit 13). For example, if the specified event is the detection of overheating of heaters 18 and 24, the log data corresponding to the event may include relevant data such as the temperature of heaters 18 and 24, the voltage applied to heaters 18 and 24, and the current flowing in heaters 18 and 24.

[0093] 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.

[0094] 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.

[0095] According to one embodiment, the control unit 12 can send status-related data (e.g., remaining capacity of the power supply 11, operating mode, etc.) of the aerosol generating device 1 to an external device via a communication link. The sent data can be output through a display or the like on the external device.

[0096] According to one embodiment, if a location retrieval 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 retrieval. For example, the control unit 12 can control the tactile unit to vibrate, or control the display to output objects corresponding to the location retrieval and the completion of the retrieval.

[0097] 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.

[0098] According to one embodiment, the control unit 12 can send data related to 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 temperature curves.

[0099] 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.

[0100] 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 shredded, granulated, or powdered forms. According to one embodiment, the additive 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 include 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 be integrated into one package by at least one wrapper. In this disclosure, the aerosol generating article may also be referred to as a stick.

[0101] 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 include 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 unit for impregnating (containing) the aerosol-generating substance. For example, the liquid delivery unit 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 unit or in a structure that contacts one side of the liquid delivery unit. Alternatively, the cartridge heater 24 may also be included in an aerosol-generating device 1 that can be separated from the cartridge.

[0102] 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.

[0103] 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.

[0104] 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 formed by recessing to a predetermined depth toward the interior of the housing 10 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.

[0105] According to one embodiment, heaters 182 and 183 can heat the aerosol-generated article 2.

[0106] Reference Figure 2a Heater 182 can be an internal heating type heater.

[0107] 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.

[0108] According to one embodiment, an internally heated heater may include a resistance heater and / or an induction heater.

[0109] For example, the resistance heater may contain a resistive material on its inner side (e.g., an internal hollow or inner surface) or outer side (e.g., an outer surface), and may 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 may be heated directly by receiving current from the power supply 11. Furthermore, the induction coil 181 may be omitted.

[0110] For example, in the case of 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 length of the heater). 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 181. The induction heating heater may include a susceptor and may generate heat based on the magnetic field generated from the induction coil 181. According to one embodiment, the induction heating heater (e.g., the susceptor) (or a heater module including it) may be arranged to be detachable from the housing 10.

[0111] 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 may be arranged side-by-side along the length direction. The first and second heaters may operate as resistance heaters and / or induction heaters, and may be heated sequentially or simultaneously. In this case, the first and second heaters may be arranged respectively at positions corresponding to the length directions of two or more aerosol generating rods. Alternatively, the first and second heaters may be arranged respectively at positions corresponding to the length directions of a first and second portion 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 may also be arranged respectively at positions corresponding to the length directions of the first and second heaters. Alternatively, the first and second induction coils may be arranged respectively at positions corresponding to the length directions of a first and second portion of a heater 182. In addition, heaters and / or induction coils may include three or more.

[0112] According to one embodiment, the sensor is arranged (or included) inside the aerosol generating article 2 (e.g., the medium section) and can be configured to heat the sensor contained inside the aerosol generating article 2 based on the magnetic field generated from the induction coil 181.

[0113] Reference Figure 2b Heater 183 can be an external heating type heater.

[0114] According to one embodiment, the externally heated heater can extend upwardly and relatively far around the periphery of 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., a cylindrical shape) with a hollow interior. The externally heated heater can also include a shape with a hollow interior and surrounding the hollow interior. 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 outer side of the aerosol generating article 2 inserted in the hollow interior.

[0115] 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 sensor, 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 a radially outward direction and applied to the outside of the housing 10.

[0116] According to one embodiment, heater 183 can also 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 apparatus 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.

[0117] and Figure 2a or Figure 2b The situation shown is different, Figure 2a heater 182 and Figure 2b The heater 183 can be included together with the aerosol generating device 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.

[0118] According to one embodiment, an airflow channel for air circulation can be provided in the aerosol generating device 1. For example, the housing 10 may include structures (e.g., holes) that allow 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).

[0119] Figure 3a This is a schematic diagram of an aerosol generating apparatus 200 according to one embodiment. Figure 3b This is a schematic diagram of an aerosol generating apparatus 200 and an aerosol generating article 201 according to one embodiment. Figure 3c yes Figure 3b The diagram shows region A of the aerosol-generating article 201.

[0120] Reference Figure 3a , Figure 3b and Figure 3c According to one embodiment of the aerosol generating apparatus 200 (e.g., Figure 1 , Figure 2a and Figure 2b The aerosol generating device 1) may include a housing 210 and a magnetic sensor 250 (e.g., Figure 1 Sensor section 13).

[0121] Hereinafter, any repetitive descriptions related to the above description will be omitted. It should be understood that in the aerosol generating apparatus 200, certain components and structures can be substituted, added, or omitted to the extent readily understood by those skilled in the art with reference to the accompanying drawings and the following description. Furthermore, unless it is clearly not technically feasible, at least one component or feature of the above embodiments can be incorporated into the aerosol generating apparatus 200.

[0122] In one embodiment, the housing 210 may form the exterior of the aerosol generating device 200. Alternatively, the housing 210 may house other components of the aerosol generating device 200. The housing 210 may be the body or main body of the aerosol generating device 200.

[0123] In one embodiment, the housing 210 may include an intake port 211. The intake port 211 may be an opening or hole for the aerosol-generating article 201 (e.g., Figure 2a and Figure 2b 2) Insertion of the aerosol-generating article. The suction port 211 may be formed as an opening on one side of the housing 210 (e.g., the upper surface or the face in the +Z direction).

[0124] Hereinafter, objects inserted into the aerosol generating apparatus 200 according to various embodiments of the present disclosure will be described as rod-shaped aerosol generating articles 201, but in practical applications of the aerosol generating apparatus 200, they are not limited to this, and the aerosol generating articles 201 can be replaced with various shapes and structures, such as cartridges or capsules.

[0125] In one embodiment, the housing 210 may include a cavity 213. The aerosol generating article 201 may be inserted into the cavity 213. The cavity 213 may be an elongated cavity, a bonding region, an insertion region, or a heating region for accommodating the aerosol generating article 201.

[0126] In one embodiment, the shape of the cavity 213 may correspond to at least a portion of the aerosol generating article 201. For example, the cavity 213 may have a cylindrical shape corresponding to the rod-shaped aerosol generating article 201.

[0127] In one embodiment, cavity 213 may communicate with inlet 211. The shape of cavity 213 may extend from inlet 211 in a direction (e.g., the -Z direction). Aerosol generating article 201 may pass through inlet 211 along its length (e.g., along the Z-axis direction) and be inserted into cavity 213. In one embodiment, the magnetic sensor 250 may be disposed within the cavity 213. The magnetic sensor 250 may detect magnetic information related to the aerosol generating article 201. Alternatively, the magnetic sensor 250 may detect whether the aerosol generating article 201 is inserted into the cavity 213.

[0128] In one embodiment, the aerosol generating article 201 may include a magnetic printout 203. The magnetic printout 203 may be disposed on at least a portion of the outer peripheral surface of the aerosol generating article 201.

[0129] In one embodiment, magnetic information may be recorded on a magnetic printout 203. When the aerosol generating article 201 is inserted into the cavity 213, the magnetic printout 203 may electromagnetically interact with a magnetic sensor 250. The magnetic sensor 250 may electromagnetically interact with the magnetic printout 203 to identify the magnetic information recorded on the magnetic printout 203.

[0130] In one embodiment, the magnetic printed material 203 can be magnetized along a predetermined direction. The magnetic sensor 250 can detect the magnetization direction of the magnetic printed material 203 and identify the magnetic information recorded on the magnetic printed material 203.

[0131] In one embodiment, the magnetic printed material 203 may include a plurality of magnetized regions 203a, 203b, 203c, and 203d. Each of the plurality of magnetized regions 203a, 203b, 203c, and 203d may be magnetized along a predetermined direction.

[0132] For example, such as Figure 3c As shown, each of the multiple magnetization regions 203a, 203b, 203c, and 203d can be made of a metallic material, and the metallic material can be magnetized such that its N pole faces any one of the following directions: a first direction (e.g., the upper side or the +Z direction), a second direction (e.g., the left side or the -X direction), a third direction (e.g., the right side or the +X direction), and a fourth direction (e.g., the lower side or the -Z direction).

[0133] In one embodiment, such as Figure 3c As shown, each of the multiple magnetization regions 203a, 203b, 203c, and 203d can be magnetized in different directions. However, Figure 3c For example only, at least a portion of the multiple magnetization regions 203a, 203b, 203c, and 203d may be magnetized in the same direction.

[0134] In one embodiment of this disclosure, the magnetic printed material 203 can constitute magnetic information related to the aerosol generating article 201 by configuring the magnetization direction of each of the plurality of magnetized regions 203a, 203b, 203c, 203d in various ways.

[0135] Furthermore, despite Figure 3c The diagram shows four magnetization regions 203a, 203b, 203c, and 203d, but this is only an example. These magnetization regions 203a, 203b, 203c, and 203d can be a single region or more than two regions. Furthermore, as... Figure 3c As shown, the multiple magnetization regions 203a, 203b, 203c, and 203d can be arranged in the vertical direction, or at least a portion of the multiple magnetization regions 203a, 203b, 203c, and 203d can be adjacent to each other in the horizontal direction, or can be arranged according to a predetermined pattern or shape.

[0136] In one embodiment, the magnetization direction, arrangement, pattern, and / or shape of multiple magnetized regions 203a, 203b, 203c, and 203d of the magnetic printed material 203 can be determined based on information about the aerosol-generated article 201 (e.g., type of aerosol-generated article 201, whether it is genuine, type of materials contained therein, and / or content ratio, etc.). The magnetic sensor 250 can identify magnetic information related to the aerosol-generated article 201 from the magnetic printed material 203.

[0137] In one embodiment, the magnetic sensor 250 may be constructed from a magnetoresistive (MR) sensor, the resistance of which varies with the magnetic field inside the cavity 213. The magnetic sensor 250, constructed from an MR sensor, is advantageous for measuring the strength and direction of the magnetic field generated by the magnetic printed material 203.

[0138] In one embodiment, the magnetic sensor 250 may be a triaxial sensor that detects changes in the magnetic field along three mutually orthogonal axes within the cavity 213. The triaxial magnetic sensor 250 can more accurately and precisely identify the magnetization direction of each of the multiple magnetization regions 203a, 203b, 203c, and 203d.

[0139] In one embodiment, at least one processor 260 (e.g., Figure 1 , Figure 2a and Figure 2b The control unit 12) can receive detection results from the magnetic sensor 250. The memory 270 (e.g., Figure 1 The memory 17) can be operatively connected to at least one processor 260 and can store executable instructions. At least one processor 260 can control the drive of the aerosol generating device 200 by executing the instructions stored in the memory 270.

[0140] In one embodiment, at least one processor 260 may receive detection results from the magnetic sensor 250 and execute instructions stored in the memory 270 regarding the magnetic sensor 250, thereby identifying magnetic information related to the aerosol generating article 201 based on the detection results of the magnetic sensor 250.

[0141] In one embodiment, the memory 270 of the aerosol generating apparatus 200 may have appropriate temperature profiles and drive-related information based on various information (e.g., the type of aerosol generating article 201, the type of materials contained therein, the proportion of materials, the content of materials, and the degree of over-humidity).

[0142] In one embodiment, heater 230 (e.g., Figure 1 heaters 18, 24, Figure 2a heater 182 or Figure 2b The heater 183 can heat the aerosol generating article 201 inserted into the cavity 213. The heater 230 can heat the aerosol generating article 201 to generate aerosol.

[0143] In one embodiment, the heater 230 may be driven by at least one processor 260. The at least one processor 260 may control the drive of the heater 230 based on magnetic information detected by the magnetic sensor 250.

[0144] For example, at least one processor 260 may execute instructions from memory 270 on drive-related information (e.g., drive time, drive cycle, drive intensity, etc.) of heater 230 based on the identified magnetic information, thereby executing a drive adapted to aerosol generating article 201.

[0145] In one embodiment of this disclosure, the aerosol generating device 200 can provide customized actuation for the aerosol generating article 201 via a magnetic sensor 250. The aerosol generating device 200 can provide users with an improved user experience for various aerosol generating articles 201.

[0146] In one embodiment of this disclosure, even if the user does not input information related to the aerosol generating article 201 or does not directly control the drive of the aerosol generating device 200, the aerosol generating device 200 can still identify the identification information related to the aerosol generating article 201 identified by the magnetic sensor 250, and automatically customize and control the drive of the aerosol generating device 200 based on this information.

[0147] In one embodiment, when the heater 230 is activated, the magnetic printed material 203 can be heated by the heater 230, thereby reducing or eliminating the recording associated with magnetic information. Alternatively, the magnetic printed material 203 can provide the magnetic sensor 250 with information regarding whether the aerosol-generating article 201 has been used.

[0148] For example, after the magnetic printed part 203 is heated by the heater 230, the magnetic field strength formed by the electromagnetic interaction between the magnetic printed part 203 and the magnetic sensor 250 may weaken.

[0149] In one embodiment, the magnetic sensor 250 can determine whether the aerosol-generating article 201 has been reused based on whether the magnetic field strength related to the magnetic information recorded on the magnetic printed material 203 is below a reference value.

[0150] In one embodiment of this disclosure, the aerosol generating apparatus 200 can reduce or eliminate the magnetic information associated with the magnetic printed material 203 by the heater 230, thereby preventing the aerosol generating article 201 from being reused or recycled.

[0151] In one embodiment of this disclosure, when the aerosol generating device 200 detects a weak magnetic field strength for magnetic information via the magnetic sensor 250, the aerosol generating device 200 can prevent the user from using the aerosol generating article 201 by limiting the drive of the heater 230.

[0152] For example, when the aerosol-generating article 201 is reused or recycled, it may produce aerosols with a different composition than when it was first used, which may produce harmful substances and reduce the user's smoking experience.

[0153] In one embodiment of this disclosure, when the aerosol generating article 201 is used for the first time, the aerosol generating device 200 can weaken or eliminate the magnetic information related records of the magnetic printed material 203, and the magnetic sensor 250 can prevent the aerosol generating article 201 from being reused or recycled by detecting the magnetic field strength related to the magnetic information.

[0154] Figure 4 This is a flowchart of a control method 300 for an aerosol generating apparatus according to an embodiment.

[0155] Reference Figure 4 According to one embodiment, the aerosol generation device control method 300 may include at least a portion of magnetic information recognition action 310, magnetic field strength judgment action 330, heater driving action 335, and secondary use recognition action 340.

[0156] Hereinafter, any repetitive descriptions related to the above description will be omitted. It should be understood that in the aerosol generating apparatus and control method 300, certain components and structures can be replaced, added, or omitted to the extent readily understood by those skilled in the art with reference to the accompanying drawings and the following description. Furthermore, unless it is technically clearly impractical, at least one component or feature of the above embodiments can be incorporated into the aerosol generating apparatus and control method 300.

[0157] In one embodiment, each action of the control method 300 for the aerosol generating apparatus can be executed by at least one processor executing instructions stored in a memory. Alternatively, the control method 300 for the aerosol generating apparatus can be executed by a main processor, or by a main processor, an auxiliary processor, or other components.

[0158] According to one embodiment, the control method 300 for the aerosol generating apparatus can be based on the aforementioned aerosol generating apparatus (e.g., Figure 1 , Figure 2a and Figure 2b aerosol generating device 1 or Figure 3a and Figure 3b The control method 300 is an aerosol generating device 200, but the embodiments are not limited to this, and may also be a control method 300 for controlling aerosol generating devices of other types, shapes, structures and components.

[0159] In one embodiment, during the magnetic information recognition action 310, a magnetic sensor can identify magnetic information from an article inserted into the aerosol generating device. The magnetic sensor can electromagnetically interact with the magnetic printed part of the inserted aerosol generating article to obtain information related to the aerosol generating article.

[0160] However, despite Figure 4The magnetic information recognition action 310 is shown to be executed before the magnetic field strength determination action 330, but this is only one example of the control method 300. For example, the magnetic information recognition action 310 may also be executed after the magnetic field strength determination action 330, and specifically, it may be executed before the heater driving action 335.

[0161] In one embodiment, the magnetic field strength determination action 330 can determine whether the magnetic field strength related to the magnetic information identified by the magnetic sensor is below a reference value R0. The reference value R0, used as the determination criterion, can be a value of 1 / 2, 1 / 2, or less of the magnetic field strength generally or on average associated with articles generated without aerosols.

[0162] For example, using a magnetically printed piece without an aerosol-generating article, the average (or median) magnetic field strength detected by the magnetic sensor can be R (A / m), while the reference value R0 used as a judgment standard can be 0.5R (A / m). When an aerosol-generating article is inserted, if the magnetic field strength detected by the magnetic sensor is below 0.5 R (A / m), the aerosol-generating device can determine that the inserted aerosol-generating article has been reused.

[0163] In one embodiment, in the control method 300, when the magnetic field strength related to the magnetic information identified by the magnetic sensor is greater than a reference value R0, a heater driving action 335 can be executed. In the heater driving action 335, the heater can be driven in a way that is adapted to the aerosol generating article based on the magnetic information.

[0164] In one embodiment, in the control method 300, when the magnetic field strength related to the magnetic information identified by the magnetic sensor is below a reference value R0, a secondary use identification action 340 can be executed. In the secondary use identification action 340, the driving conditions of the heater, such as driving time, driving cycle, and driving intensity, can be controlled according to the magnetic information and adapted to the aerosol generating article.

[0165] Figure 5 This is a flowchart of a control method 300 for an aerosol generating apparatus according to an embodiment.

[0166] Reference Figure 5 The control method 300 of an aerosol generating apparatus according to one embodiment may include at least a portion of heater drive limiting action 341, user notification action 343, input signal receiving action 345, and heater drive action 347.

[0167] Hereinafter, any repetitive descriptions related to the above description will be omitted. It should be understood that in the aerosol generating apparatus and control method 300, certain components and structures can be replaced, added, or omitted to the extent readily understood by those skilled in the art with reference to the accompanying drawings and the following description. Furthermore, unless it is technically clearly impractical, at least one component or feature of the above embodiments can be incorporated into the aerosol generating apparatus and control method 300.

[0168] Figure 5 This is a flowchart schematically illustrating the actions that the control method 300 can perform after the secondary use identification action 340 of the aerosol-generated article.

[0169] In one embodiment, after the secondary use of the identification action 340, the control method 300 may execute at least one of the heater drive restriction action 341 and the user notification action 343, or both simultaneously.

[0170] In one embodiment, in heater drive limiting action 341, when it is detected that the aerosol-generating article has been reused, the power supply to the heater can be cut off. Since the reuse of the aerosol-generating article may produce aerosols with different compositions than those produced during the first use, or may produce harmful substances, and may reduce the user's smoking experience, the reuse of the aerosol-generating article can be prevented by limiting the operation of the heater.

[0171] In one embodiment, the user notification action 343 can be performed via an output unit (e.g., Figure 1 The output unit 14) outputs secondary use-related information to the user, wherein the output unit displays audio information, vibration information, optical information, or visual information. For example, the user notification action 343 may include at least a portion of multiple output methods 343a, 343b, 343c, and 343d.

[0172] In one embodiment, the audio output action 343a may send a prompt tone or guidance content to the user. In one embodiment, the haptic drive action 343b may send a vibration signal to the user. In one embodiment, the optical output action 343c may output a flashing light signal or light of a predetermined color to the user. In one embodiment, the screen display action 343d may output secondary use guidance to the user through a display.

[0173] In one embodiment, during the input signal receiving operation 345, the input signal can be received via an input unit (e.g., Figure 1 The input section 15 receives input signals from another component (e.g., an inserted sensing sensor), a user, or an external device. For example, the input signal may be a heater drive recovery signal or a forced drive signal.

[0174] In one embodiment, in the control method 300, when an input signal is received, the heater drive limiting action 341 can be terminated, and the heater drive action 347 can be performed. In the heater drive action 347, the heater can be driven.

[0175] Figure 6 This is a flowchart of a control method 300 for an aerosol generating apparatus according to an embodiment.

[0176] Reference Figure 6 The control method 300 of an aerosol generating apparatus according to one embodiment may include at least a portion of a reference value derivation action 320 and a database update action 325.

[0177] Hereinafter, any repetitive descriptions related to the above description will be omitted. It should be understood that in the aerosol generating apparatus and control method 300, certain components and structures can be replaced, added, or omitted to the extent readily understood by those skilled in the art with reference to the accompanying drawings and the following description. Furthermore, unless it is technically clearly impractical, at least one component or feature of the above embodiments can be incorporated into the aerosol generating apparatus and control method 300.

[0178] Figure 6 This is a flowchart schematically illustrating the actions that the control method 300 can perform before the magnetic field strength determination action 330 of the aerosol generating article.

[0179] In one embodiment, during the reference value derivation action 320, a suitable reference value R0 can be retrieved from the memory based on magnetic information. The memory may store reference values ​​related to the magnetic field strength, which serve as the basis for determining whether the magnetic field has been reused. During the reference value derivation action 320, a suitable reference value, serving as the benchmark for determining whether the magnetic field has been reused, can be retrieved from multiple reference values ​​based on the magnetic information identified by the magnetic sensor.

[0180] For example, the reference value R0 may need to be adjusted based on various factors, such as the region and environment in which the aerosol generating device is used, the production environment of the aerosol-generating article, and the circulation path of the aerosol-generating article. For instance, the magnetic printing of aerosol-generating articles may be weakened if they are circulated in areas with higher average temperatures or during periods of higher average temperatures. The control method 300 takes such cases into account and can adjust and derive the reference value R0 based on magnetic information.

[0181] In one embodiment, during database update action 325, the update can be performed via a communication unit (e.g., Figure 1The information input by the communication unit 16) is used to update the database related to the reference values ​​stored in the memory. For example, in the database update action 325, the value of the reference value can be adjusted, a new reference value can be added, or duplicate or unnecessary reference values ​​can be deleted from multiple reference values.

[0182] Figure 7 This is a flowchart of a control method 300 for an aerosol generating apparatus according to an embodiment.

[0183] Reference Figure 7 According to one embodiment, the control method 300 of the aerosol generating device may include an article insertion detection action 305, an improper use identification action 325, and a heater drive restriction action 315.

[0184] Hereinafter, any repetitive descriptions related to the above description will be omitted. It should be understood that in the aerosol generating apparatus and control method 300, certain components and structures can be replaced, added, or omitted to the extent readily understood by those skilled in the art with reference to the accompanying drawings and the following description. Furthermore, unless it is technically clearly impractical, at least one component or feature of the above embodiments can be incorporated into the aerosol generating apparatus and control method 300.

[0185] Figure 7 This is a flowchart schematically illustrating the actions that the control method 300 can perform before the magnetic field strength determination action 330 of the aerosol generating article.

[0186] In one embodiment, during the item insertion detection action 305, an insertion sensing sensor (e.g., Figure 1 The sensor unit 13) detects whether an aerosol-generating article or other article is inserted into the cavity. In the magnetic information recognition operation 310, it can determine whether magnetic information is recognized when the insertion of an article is detected.

[0187] In one embodiment, when no magnetic information is detected by the magnetic sensor in the magnetic information recognition action 310, the control method 300 may identify that the article has been misused. In the misuse recognition action 311, it may be identified that the article inserted into the cavity has been misused or reused. For example, when the inserted article is a counterfeit, a damaged article, or has been misused, the magnetic printing may be absent or damaged.

[0188] In one embodiment, in control method 300, by executing heater drive limiting action 315 after improper use identification action 311, the power supplied to the heater can be cut off or the heater drive can be temporarily limited. Although not shown in the figure, control method 300 may execute an action to notify the user of the situation together with the execution of improper use identification action 311.
