Description

Technical Field

[0001] Various embodiments of this disclosure relate to cartridges and aerosol generating apparatus including cartridges, and more specifically, to cartridges having a structure for sensing the remaining amount of liquid composition stored in the cartridge and an aerosol generating apparatus including the cartridge. Background Technology

[0002] In recent years, there has been a growing demand for alternatives to overcome the drawbacks of regular cigarettes. For example, there is increasing demand for systems that generate aerosols by heating cigarettes or aerosol-generating substances using an aerosol-generating device, rather than burning the cigarettes. Consequently, research into heated aerosol-generating devices is actively underway.

[0003] Aerosol generating devices have additional functions that provide convenience to users. For example, in the case of an aerosol generating device using a liquid aerosol generating substance, it has the function of providing the user with information about the remaining amount of aerosol generating substance or controlling the operation of the aerosol generating device based on the remaining amount of aerosol generating substance. Summary of the Invention

[0004] Technical issues

[0005] Under normal circumstances, the cartridges of aerosol generating devices that store aerosol-generating substances in liquid form are used as consumables. That is, the cartridge needs to be replaced when all the aerosol-generating substances stored in it are consumed. Even when the cartridge is not a consumable, the user needs to refill it with aerosol-generating substances when the aerosol-generating substances are used up.

[0006] If users cannot visually confirm the remaining amount of aerosol-generating material inside the cartridge, they cannot predict when the cartridge will need to be replaced or when the aerosol-generating material will be replenished. Therefore, it is necessary to apply technology to aerosol-generating devices that monitor the remaining amount of aerosol-generating material.

[0007] The embodiment provides a smoke cartridge with a structure capable of monitoring the remaining amount of aerosol-generating substances.

[0008] The embodiment provides an aerosol generating apparatus capable of controlling the operation of other components in accordance with the remaining amount of aerosol generating material stored in the cartridge.

[0038] Figure 1 This is a block diagram of an aerosol generating apparatus 1 according to one embodiment.

[0039] According to one embodiment, the aerosol generating apparatus 1 may include a power supply 11, a control unit 12, a sensor unit 13, an output unit 14, an input unit 15, a communication unit 16, a memory 17, and / or heaters 18 and 24. However, those skilled in the art will understand that, according to the design of the aerosol generating apparatus 1, certain components may be omitted. Figure 1 The shown components may include some of the constituent elements, or new constituent elements may be added.

[0040] According to one embodiment, the sensor unit 13 can sense the state of the aerosol generating device 1 or the state around the aerosol generating device 1, and transmit the sensed information to the control unit 12. For example, the sensor unit 13 may include a temperature sensor, a puff sensor, an insertion sensor, a reuse sensor, an overly moist sensor, a cigarette identification sensor, a cartridge sensor, a cap sensor, and / or a motion sensor. In addition, the sensor unit 13 may also include various sensors such as a liquid level sensor for sensing the remaining liquid in the cartridge and a water immersion sensor for sensing water immersion in the aerosol generating device 1.

[0041] 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.

[0042] As an example, the temperature sensor may include a resistive element (e.g., a thermistor) whose resistance value changes in response to temperature changes in the heaters 18 and 24. The temperature sensor may output a signal corresponding to the resistance value of the resistive element, and the control unit 12 may detect the temperature and / or temperature changes of the heaters 18 and 24 based on the aforementioned signal corresponding to the resistance value.

[0043] As another example, the temperature sensor may include a sensor that detects the resistance value of heaters 18 and 24. The temperature sensor may output a signal corresponding to the resistance value of heaters 18 and 24, and the control unit 12 may detect the temperature and / or temperature change of heaters 18 and 24 based on the aforementioned signal corresponding to the resistance value.

[0044] According to one embodiment, a temperature sensor can sense the temperature of the power supply 11. The temperature sensor can be arranged adjacent to the power supply 11. For example, the temperature sensor can be attached to a surface of the power supply 11 (e.g., a battery) and / or mounted on a surface of a printed circuit board. As an example, the aerosol generating apparatus 1 may include a power protection circuit (PCM), and the temperature sensor can be arranged adjacent to the power supply 11 together with the power protection circuit.

[0045] 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).

[0046] According to one embodiment, the suction sensor can sense the user's suction.

[0047] As an example, the suction sensor may include a pressure sensor. The pressure sensor can output a signal corresponding to the internal pressure of the aerosol generating device 1, and the control unit 12 can detect the user's suction based on the aforementioned signal corresponding to the internal pressure. The internal pressure of the aerosol generating device 1 may correspond to the pressure of the gas flow channel. The suction sensor may be arranged in the aerosol generating device 1 corresponding to the gas flow channel.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] According to one embodiment, the insertion sensing sensor is capable of sensing the insertion and / or removal of an aerosol-generating article. The insertion sensing sensor may be disposed around the periphery of the insertion space. Furthermore, the insertion sensing sensor may also include any combination of the examples described above.

[0053] 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.

[0054] As another example, the insertion sensing sensor may include an inductive sensor. The inductive sensor may include at least one coil, and the at least one coil may be arranged adjacent to the insertion space. When the aerosol generating article (e.g., a wrapper of the aerosol generating article) includes a conductor, a change in the magnetic field may be generated around the coil through which the current flows when the aerosol generating article is inserted into or removed from the insertion space. The control unit 12 may sense the insertion and / or removal of the aerosol generating article including the conductor based on the characteristics of the current output from or sensed by the inductive sensor (e.g., the frequency, current value, voltage value, inductance value, impedance value, etc. of the alternating current). Alternatively, an inductive heating element (SUS) may also be included in the aerosol generating article (e.g., the dielectric portion of the aerosol generating article). Even in this case, the magnetic field around the coil may change based on the insertion or removal of the heating element or the like in the insertion space, and the control unit 12 can sense the insertion and / or removal of the aerosol generating article based on the current characteristics of the inductive sensor.

[0055] 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.

[0056] According to one embodiment, a reuse sensing sensor can detect whether an aerosol-generating article has been reused. As an example, the reuse sensing sensor can be a color sensor for sensing the color of the aerosol-generating article. If a user uses the aerosol-generating article, the color of a portion of the outer casing of the aerosol-generating article may change due to the generated aerosol or heating. The color sensor can output a signal corresponding to the optical characteristics (e.g., wavelength of light) of the color of the outer casing based on the light reflected from it. If a color change is detected in a portion of the outer casing, the control unit 12 can determine that the aerosol-generating article inserted into the insertion space has been used.

[0057] According to one embodiment, an over-humidity sensing sensor can sense whether an aerosol-generating article is in an over-humid state. For example, the over-humidity sensing sensor may include a capacitive sensor. The capacitive sensor may include at least one conductor arranged adjacent to the insertion space. The control unit 12 can detect whether the aerosol-generating article is in an over-humid state based on the level of a signal corresponding to the dielectric constant, etc., output from the capacitive sensor. As an example, the control unit 12 can confirm the level range that the signal level falls into according to a lookup table, and determine the moisture content of the aerosol-generating article based on the confirmed level range.

[0058] 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.

[0059] As an example, a cigarette identification sensor may include a light sensor for sensing an identification substance (or identification mark) located on the outer surface (e.g., packaging component) of an aerosol-generating article. The light sensor may illuminate the identification substance (or identification mark) of the aerosol-generating article and sense whether the aerosol-generating article is genuine and / or its type based on the reflected light. For example, the identification substance may include a substance that emits light of a specific wavelength based on the illuminated light. The control unit 12 may detect whether the aerosol-generating article is genuine and / or its type based on the range of said wavelengths.

[0060] 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.

[0061] As another example, a cigarette identification sensor may include an inductive sensor. When the packaging and / or interior (e.g., the dielectric portion) of the aerosol-generating article inserted into the insertion space includes a conductor, the characteristics of the current sensed by the inductive sensor (e.g., frequency, current value, voltage value, inductance value, impedance value, etc.) may vary depending on the type of aerosol-generating article inserted into the insertion space. The control unit 12 can detect whether the inserted aerosol-generating article is genuine and / or its type based on the characteristics of the current output from or sensed by the inductive sensor.

[0062] 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.

[0063] 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.

[0064] According to one embodiment, the cap sensing sensor can sense the installation and / or removal of the cap. For example, the cap sensing sensor may include an inductive sensor, a capacitive sensor, a resistive sensor, a contact sensor, a Hall effect sensor (HAL IC), and / or an optical sensor. The cap may include a structure that covers at least a portion of a cartridge mounted or inserted into the aerosol generating device 1, or covers at least a portion of the housing of the aerosol generating device 1. If the cap is installed in or removed from the housing, the cap sensing sensor can output a signal corresponding to the installation or removal, and the control unit 12 can sense the installation or removal of the cap based on the signal corresponding to the installation or removal.

[0065] According to one embodiment, the motion sensing sensor is capable of sensing the motion of the aerosol generating device 1. The motion sensing sensor can be implemented by at least one of an accelerometer and a gyroscope.

[0066] 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.

[0067] According to one embodiment, the output unit 14 can output information about the status of the aerosol generating device 1. The output unit 14 may include, but is not limited to, a display, a haptic unit, and / or an audio output unit. For example, the information about the aerosol generating device 1 may include the charging / discharging status of the power supply 11, the preheating status of the heaters 18 and 24, the insertion / removal status of the aerosol generating article and / or cartridge, the installation and / or removal status of the cover, or a status where the use of the aerosol generating device 1 is restricted (e.g., abnormal object detected). The display can visually provide the user with information about the status of the aerosol generating device 1. For example, the display may include a light-emitting diode (LED), a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. If the display includes a touchpad, the display can also be used as an input unit 15. The haptic unit can tactilely provide the user with information about the status of the aerosol generating device 1. For example, the tactile part may include a vibrating motor, a piezoelectric element, an electrical stimulation device, etc. The sound output part can provide the user with information about the aerosol generating device 1 in an auditory manner. For example, the sound output part can convert an electrical signal into a sound signal and output the sound signal to the outside.

[0068] According to one embodiment, the power source 11 can supply power for the operation of the aerosol generating apparatus 1. The power source 11 may include one or more batteries. The power source 11 can supply power to heat the heaters 18 and 24. Furthermore, the power source 11 can supply power required for the operation of other components included in the aerosol generating apparatus 1, such as the control unit 12, sensor unit 13, output unit 14, input unit 15, communication unit 16, and memory 17. The power source 11 can be a rechargeable battery or a disposable battery. For example, the power source 11 can be a lithium polymer (LiPoly) battery, but is not limited thereto. The power source 11 can be a replaceable (detachable) battery (hereinafter, a removable battery). The removable battery can be installed in a battery housing provided within the aerosol generating apparatus 1, or it can be removed from the battery housing. The removable battery can be charged via wired and / or wireless means.

[0069] 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).

[0070] According to one embodiment, heaters 18 and 24 can be resistance heaters. For example, resistance heaters can include resistive materials such as metals or metal alloys like titanium, zirconium, tantalum, platinum, nickel, cobalt, chromium, hafnium, niobium, molybdenum, tungsten, tin, gallium, manganese, iron, copper, stainless steel, and nichrome. Resistance heaters can be implemented using metal heating wires, metal heating plates with conductive tracks, or ceramic heating elements.

[0071] According to one embodiment, heaters 18 and 24 can be induction heating heaters. For example, an induction heating heater may include an induction heating element (susceptor) that heats up by a magnetic field. An alternating current flowing through an induction coil can generate a magnetic field in the induction coil. The generated magnetic field can pass through the heater and can generate eddy currents in the induction heating element. Based on the generation of eddy currents, the induction heating element can be heated. According to one embodiment, the induction heating element may also be included inside an aerosol generating article (e.g., a medium section). In this case, the induction heating element included inside the aerosol generating article can also be heated by an induction coil.

[0072] Heaters 18 and 24 are not limited to the examples above, and may include various heating methods, structures, components, etc. for heating aerosol generating articles and / or smoke cartridges, or may be used in place of them.

[0073] 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 keyboard, a dome switch, a jog wheel, a jog switch, etc.

For example, the memory 17 may store data such as the operating time of the aerosol generating device 1, the maximum number of puffs, the current number of puffs, at least one temperature profile, and data regarding the user's smoking pattern.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on the insertion and / or removal of the aerosol-generating article relative to the insertion space. For example, if the insertion sensing sensor (e.g., sensor unit 13) determines that the aerosol-generating article has been inserted into the insertion space, the control unit 12 can control the supply of power to the heaters 18 and 24. If the insertion sensing sensor (e.g., sensor unit 13) determines that the aerosol-generating article has been removed from the insertion space, the control unit 12 can cut off the power supply to the heaters 18 and 24. If the temperature of the heaters 18 and 24 is above a limit temperature or the temperature change slope of the heaters 18 and 24 is above a set slope, the control unit 12 can determine that the aerosol-generating article has been removed from the insertion space.

[0087] 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.

[0088] 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.

[0089] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on whether the cartridge is attached and / or removed. For example, if the cartridge sensing sensor (e.g., sensor unit 13) determines that the cartridge is in a separated state, the control unit 12 can control the interruption of the power supply to the heaters 18 and 24 or prevent the supply of power to the heaters 18 and 24.

[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 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.

[0091] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on whether the e-cigarette cartridge is available. For example, if the control unit 12 determines, based on data stored in the memory 17, that the current number of puffs exceeds the maximum number of puffs set for the e-cigarette cartridge, it can determine that the e-cigarette cartridge cannot be used. Alternatively, the control unit 12 can determine that the e-cigarette cartridge cannot be used if the total heating time of the heaters 18 and 24 exceeds a preset maximum time or if the total electrical power supplied to the heaters 18 and 24 exceeds a preset maximum electrical power. In this case, the control unit 12 can control the power supply to the heaters 18 and 24 to be interrupted or not to be supplied with power.

[0092] According to one embodiment, the control unit 12 can control the power supply to the heaters 18 and 24 based on the user's suction. For example, the control unit 12 can use a suction sensor (e.g., sensor unit 13) to determine whether suction has occurred and / or the intensity of suction. If the number of suctions has reached a preset maximum number of suctions and / or no suction is detected for a preset time, the control unit 12 can cut off the power supply to the heaters 18 and 24. When suction is sensed, the control unit 12 can control the power supply to the heaters 18 and 24.

[0093] 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).

[0094] According to one embodiment, the control unit 12 can control the output unit 14 based on the results sensed by the sensor unit 13. For example, if the number of suctions counted by the suction sensor (e.g., sensor unit 13) reaches a preset number, the control unit 12 can control the output unit 14 to provide information that the aerosol generating device 1 is about to end its operation in a visual, tactile, and / or audible manner. For example, the control unit 12 can control the output unit 14 to provide information about the temperature of the heaters 18 and 24 in a visual, tactile, and / or audible manner.

[0095] According to one embodiment, the control unit 12 can store and update the history of events that have occurred in the memory 17 based on the occurrence of predetermined events. For example, events may include operations performed in the aerosol generating apparatus 1 such as sensing the insertion of an aerosol generating article, starting heating of the aerosol generating article, sensing suction, ending suction, sensing overheating of heaters 18 and 24, sensing overvoltage applied to heaters 18 and 24, ending heating of the aerosol generating article, turning the power supply of the aerosol generating apparatus 1 on / off, starting charging of the power supply 11, sensing overcharging of the power supply 11, and ending charging of the power supply 11. For example, the history of events may include the date and time of the event, log data corresponding to the event, etc. For example, if the predetermined event is sensing the insertion of an aerosol generating article, the log data corresponding to the event may include data such as the sensing value of the insertion sensing sensor (e.g., sensor unit 13). For example, if the predetermined event is the sensing of overheating of heaters 18 and 24, the log data corresponding to the event may include data about the temperature of heaters 18 and 24, the voltage applied to heaters 18 and 24, the current flowing in heaters 18 and 24, etc.

[0096] 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.

[0097] 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.

[0098] According to one embodiment, the control unit 12 can send data about the status of the aerosol generating device 1 (e.g., remaining capacity of the power supply 11, operating mode, etc.) to an external device via a communication link. The sent data can be output through a display or the like on the external device.

[0099] According to one embodiment, if a location search request for the aerosol generating device 1 is received from an external device via a communication link, the control unit 12 can control the output unit 14 to perform an operation corresponding to the location search. For example, the control unit 12 can control the tactile unit to vibrate, or control the display to output objects corresponding to the location search and the end of the search.

[0100] 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.

[0101] According to one embodiment, the control unit 12 can send data about the detection values ​​of at least one sensor unit 13 to an external server (not shown) via a communication link, and can receive and store a learning model generated by learning the detection values ​​through machine learning such as deep learning from the server. The control unit 12 can use the learning model received from the server to perform operations such as determining the user's inhalation pattern and generating a temperature curve.

[0102] 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.

[0103] The aerosol generating article mentioned in this disclosure may include at least one aerosol generating rod (e.g., a medium section) and at least one filter rod. The heater 18 may be arranged corresponding to at least one aerosol generating rod and may be designed differently depending on the arrangement and / or position of the aerosol generating rod and the filter rod. The aerosol generating rod may contain at least one of nicotine, an aerosol generating substance, and additives. For example, the aerosol generating substance may contain glycerin (e.g., vegetable glycerin (VG)) and / or propylene glycol (PG), or may contain a variety of other substances. For example, the additive may contain flavoring agents and / or organic acids, or may contain a variety of other substances. For example, the aerosol generating rod may contain an aerosol generating substrate (e.g., a sheet) impregnated with a liquid non-tobacco substance (e.g., the aerosol generating substance and / or nicotine), and / or may contain solid tobacco substances (e.g., tobacco leaves, reconstituted tobacco, etc.). Tobacco substances can be contained in the aerosol generating rod in various forms such as shreds, granules, and powder. According to one embodiment, the additives in the aerosol generating rod may contain an alkaline substance. Based on the alkaline substance, the nicotine in the tobacco substances contained in the aerosol generating rod can have an alkaline pH value (e.g., pH 7.0 or higher). In this case, the aerosol generating rod can release free base nicotine even at lower temperatures. According to one embodiment, the aerosol generating rod may comprise two or more aerosol generating rods, and the two or more aerosol generating rods may each contain tobacco substances and / or non-tobacco substances. Additionally, although not shown, at least one aerosol generating rod and at least one filter rod may each be wrapped by at least one wrapper, and / or wrapped together by at least one wrapper. In this disclosure, the aerosol generating article may also be referred to as a stick.

[0104] The cartridge mentioned in this disclosure may contain an aerosol-generating substance in any of the following states: liquid, solid, gaseous, or gel. The aerosol-generating substance may comprise a liquid composition. For example, the liquid composition may be a liquid containing substances found in tobacco (including volatile tobacco flavor components) or a liquid containing non-tobacco substances. Additionally, the cartridge may include a storage section for containing the aerosol-generating substance and / or a liquid delivery member for impregnating (containing) the aerosol-generating substance. For example, the liquid delivery member may include a core material such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic. The cartridge heater 24 may be included in the cartridge in the form of a coil surrounding (or winding) the liquid delivery member or in a structure contacting one side of the liquid delivery member. Alternatively, the cartridge heater 24 may also be included in an aerosol-generating device 1 that can be separated from the cartridge.

[0105] Figure 2 An aerosol generating apparatus 1 according to one embodiment is shown. According to one embodiment, the aerosol generating apparatus 1 may include a housing 10, a power supply 11, a control unit 12, and / or a sensor unit 13. However, those skilled in the art will understand that the constituent elements of the aerosol generating apparatus 1 are not limited to those described herein. Figure 2 The constituent elements shown may be partially omitted, or new constituent elements may be added. In the following figures, the omissions and... Figure 1 Repeated explanation.

[0106] According to one embodiment, the housing 10 may include a structure on one side for inserting or mounting the cartridge 19. In this case, the cartridge 19 can be detachably coupled to the housing 10.

[0107] Although not shown, the housing 10 and / or cartridge 19 may include a mouthpiece. The user can hold the mouthpiece in their mouth and inhale the aerosol.

[0108] According to one embodiment, the cartridge 19 may include a chamber C0 containing an aerosol-generating substance. The chamber C0 may contain the aerosol-generating substance in any of the following states: liquid, solid, gaseous, or gel. The aerosol-generating substance may comprise a liquid composition. For example, the liquid composition may be a liquid containing substances found in tobacco (including volatile tobacco flavor components) or a liquid containing non-tobacco substances.

[0109] According to one embodiment, a liquid delivery member 25 impregnated with (containing) aerosol-generating material may be included in the cartridge 19. For example, the liquid delivery member 25 may be impregnated with aerosol-generating material supplied from chamber C0. The liquid delivery member 25 may include a core material such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic. Although not shown, the aerosol generating device 1 may also include a liquid delivery member. In this case, at least a portion of the first liquid delivery member of the cartridge 19 may be in contact with at least a portion of the second liquid delivery member of the aerosol generating device 1. In this case, the first and second liquid delivery members may be implemented in different forms. For example, the first liquid delivery member may include cotton fiber, and the second liquid delivery member may include porous ceramic. Alternatively, the cartridge 19 may not include a liquid delivery member, and the aerosol-generating material of the cartridge 19 may be transferred to the liquid delivery member of the aerosol generating device 1.

[0110] According to one embodiment, an airflow channel for airflow can be provided in the housing 10 and / or the smoke cartridge 19.

[0111] For example, the housing 10 may include a structure that allows external air to flow into the interior of the housing 10 when the cartridge 19 is attached. As an example, an air inlet for allowing external air to flow into the interior of the housing 10 may be formed on one side surface of the aerosol housing 10. The air inlet may also be formed on the lower end surface of the housing 10. External air flowing into the interior of the housing 10 through the air inlet can pass through the cartridge 19 and then flow towards the user's mouth through the airflow channel CN. External air flowing in through this air inlet can pass through the cartridge 19 and flow into the user's mouth through the airflow channel CN.

[0112] For example, an airflow channel CN ​​may be included in the cartridge 19. The airflow channel CN ​​can connect the chamber (e.g., atomizing chamber) where the cartridge heater 24 or liquid delivery member 25 is disposed to the housing 10 and / or the exterior of the cartridge 19. More specifically, one end of the airflow channel CN ​​may open into the chamber (e.g., atomizing chamber) where the cartridge heater 24 or liquid delivery member 25 is disposed, and the other end may communicate with a mouthpiece. The airflow channel CN ​​may extend lengthwise along the length of the cartridge 19 on one side of the chamber C0 of the cartridge 19. The airflow channel CN ​​may also pass through the chamber C0 of the cartridge 19 and extend lengthwise along the length of the cartridge 19. The airflow channel CN ​​may also communicate with a mouthpiece separately disposed in the housing 10.

[0113] According to one embodiment, the cartridge heater 24 can heat the aerosol generating material contained in the cartridge 19. For example, the cartridge heater 24 may include a resistance heater and / or an induction heater. As an example, the resistance heater may include a resistive material and can be heated as an electric current flows through it. As another example, for an induction heater, the aerosol generating device 1 may also include an induction coil (not shown) around the periphery of the induction heater. The induction heater may include an induction heating element (susceptor) and can generate heat based on a magnetic field generated from the induction coil (not shown). The cartridge heater 24 can be formed in a coil shape that surrounds (or wraps around) the cartridge 19 and / or the liquid delivery member included in the aerosol generating device 1 and / or in a shape that contacts one side of the liquid delivery member (e.g., a patterned shape).

[0114] According to one embodiment, the cartridge heater 24 may be included in the cartridge 19. When the cartridge 19 is detachable from the housing 10, the cartridge heater 24 may be detached from the aerosol generating device 1 together with the cartridge 19. Unlike the case shown in the figures, the cartridge heater 24 may be included within the aerosol generating device 1. For example, the cartridge heater 24 may be included inside the housing 10. Alternatively, the cartridge heater 24 may be implemented as being detachable from the housing 10 separately (i.e., independently) from the cartridge 19. In other words, the cartridge heater 24 may or may not be detachable from the housing 10, regardless of whether the cartridge 19 is detached from the housing 10.

[0115] According to one embodiment, an aerosol can be generated based on the heating of the cartridge heater 24. As the liquid delivery member 25 is heated by the cartridge heater 24, an aerosol can be generated. For example, as the aerosol-generating material impregnated in the liquid delivery member 25 is heated by the cartridge heater 24, vapor can be generated from the aerosol-generating material, and as the generated vapor mixes with external air flowing into the cartridge 19, an aerosol can be generated. The aerosol generated by the cartridge heater 24 can be inhaled into the user's mouth through the airflow channel CN.

[0116] According to one embodiment, the cartridge 19 may be integrally formed with the aerosol generating device 1 (e.g., housing 10). The cartridge 19 may be configured such that the user cannot detach it from the aerosol generating device 1. Even in this case, the cartridge 19 and / or the aerosol generating device 1 may include at least one liquid delivery member 25, which is heated based on the cartridge heater 24 included in the aerosol generating device 1 or the cartridge 19 to generate an aerosol, and the generated aerosol can be inhaled into the user's mouth through the airflow channel CN.

[0117] Figure 3An aerosol generating apparatus 1 according to one embodiment is shown.

[0118] According to one embodiment, the aerosol generating device 1 may include a housing 10, a power supply 11, a control unit 12, a sensor unit 13, and / or heaters 183, 24 (e.g., Figure 1 (Heats 18, 24). However, those skilled in the art will understand that the components of the aerosol generating apparatus 1 are not limited to those described in this embodiment. Figure 3 The constituent elements shown may be partially omitted, or new constituent elements may be added. In the following figures, those omitted and... Figure 1 Repeated explanation.

[0119] According to one embodiment, the housing 10 may provide an upwardly opening space (hereinafter referred to as an insertion space) for inserting the aerosol generating article 2. The insertion space may be recessed into the interior of the housing 10 to a predetermined depth to allow at least a portion of the aerosol generating article 2 to be inserted. The lower end of the aerosol generating article 2 may be inserted into the interior of the housing 10, and the upper end of the aerosol generating article 2 may protrude outward from the housing 10.

[0120] Unlike the case shown in the attached figures, the cartridge 19 may also provide an insertion space for accommodating the aerosol generating article 2. In this case, the insertion space may be recessed into the interior of the cartridge 19 to a predetermined depth, allowing at least a portion of the aerosol generating article 2 to be inserted. The lower end of the aerosol generating article 2 may be inserted into the interior of the cartridge 19, while the upper end of the aerosol generating article 2 may protrude outward from the cartridge 19. Furthermore, in this case, the aerosol generating device 1 may not include the heater 183.

[0121] According to one embodiment, the depth of the insertion space can be greater than the length of the region of the aerosol generating article 2 containing the aerosol generating substance and / or medium. The user can hold the exposed upper end of the aerosol generating article 2 in their mouth and inhale air.

[0122] According to one embodiment, heater 183 can heat aerosol generating article 2. Heater 183 can extend relatively long upwards around the periphery of the space into which aerosol generating article 2 is inserted (i.e., the insertion space). As an example, heater 183 can be a tubular shape (e.g., cylindrical) with a hollow interior. Heater 183 can also include a shape with a hollow interior that encloses the hollow space. In this case, heater 183 can be supported by a polyimide film. A heater supported by such a film can be referred to as a film heater. Heater 183 can be arranged to surround at least a portion of the insertion space. Heater 183 can heat the outside of the hollow aerosol generating article 2 inserted therein. In this disclosure, heater 183 can be referred to as an external heating type heater that heats the outside of the aerosol generating article 2. Additionally, an insulating material can also be arranged on the outside of heater 183. This reduces the heat dissipated from heater 183 in a radially outward direction and applied to the outside of housing 10.

[0123] According to one embodiment, heater 183 may include a resistance heater and / or an induction heater.

[0124] For example, a resistance heater may include a resistive material and can be heated as an electric current flows through it. In this case, the resistance heater may be electrically connected to power source 11 and can be heated directly by receiving current from power source 11.

[0125] For example, for an induction heating heater, the aerosol generating device 1 may further include an induction coil (not shown) surrounding at least a portion of the heater 183 (e.g., arranged externally in a manner corresponding to at least a portion of the length of the heater 183). In this case, to improve the efficiency of induction heating, a magnetic flux concentrator or the like may also be included outside the induction coil (not shown). The induction heating heater may include an induction heating element (susceptor) and may generate heat based on a magnetic field generated from the induction coil (not shown).

[0126] According to one embodiment, heater 183 can also be a multiple heater. The multiple heaters may include a first heater and a second heater, and can be inserted into the aerosol generating article 2. The first and second heaters can be arranged side-by-side along the length direction. The first and second heaters can operate as resistance heaters and / or induction heaters, and can be heated sequentially or simultaneously. In this case, the first and second heaters can be arranged respectively at positions corresponding to the length directions of two or more aerosol generating rods. Alternatively, the first and second heaters can also be arranged respectively at positions corresponding to the length directions of a first and second part of an aerosol generating rod. Furthermore, when heater 183 is an induction heater, the aerosol generating device 1 may include a first induction coil and a second induction coil, which can also be arranged respectively at positions corresponding to the length directions of the first and second heaters. Alternatively, the first and second heaters can also be arranged respectively at positions corresponding to the length directions of a first and second part of a heater 183. In addition, heaters and / or induction coils may include three or more.

[0127] Unlike the case shown in the attached diagram, the aerosol generating device 1 may also exclude the heater 183. The aerosol generating article 2 may be directly or indirectly heated by the cartridge heater 24, or substantially unheated. Indirect heating means that the aerosol generating article 2 receives heat contained within the aerosol as it passes through the cartridge heater 24. In this case, the aerosol generating device 1 may be referred to as a non-heating (or, indirectly heated) aerosol generating device. The aerosol generating rod of the aerosol generating article 2 may contain additives such as alkaline substances. Based on this alkaline substance, the nicotine contained in the aerosol generating rod may have an alkaline pH (e.g., pH 7.0 or higher). This alkaline nicotine can flow into the user's mouth along with the aerosol flowing from the cartridge 19 into the aerosol generating article 2, as described later.

[0128] Unlike the case shown in the attached figures, heater 183 may also include an internally heated type heater. For example, an internally heated type heater may include various heating elements such as rod-type, tubular-type, plate-type, or needle-type heating elements. The internally heated type heater can be inserted through the lower part of the aerosol generating article 2 and can be configured to heat the inner side of the aerosol generating article 2.

[0129] According to one embodiment, the cartridge 19 can be detachably attached to the housing 10. For example, a space can be formed on one side of the housing 10, and at least a portion of the cartridge 19 can be inserted into the space formed on one side of the housing 10, so that the cartridge 19 can be installed in the housing 10. Alternatively, the cartridge 19 can be integrally formed with the housing 10.

[0130] According to one embodiment, an airflow channel for air circulation can be provided in the aerosol generating device 1 and / or the cartridge 19. For example, the housing 10 may include a structure that allows air to flow from the outside into the interior of the housing 10 when the cartridge 19 is inserted. The inflowing air can pass through the cartridge 19 and flow into the insertion space through the airflow channel CN, and can flow into the user's mouth. The airflow channel CN ​​may also include various structures for reducing residual droplets or promoting airflow.

[0131] exist Figure 3 Although the illustration shows the cartridge 19 positioned to the side of the aerosol generating article 2 and the airflow channel CN ​​forming from the side surface of the aerosol generating article 2 toward the lower end (i.e., the upstream side) of the aerosol generating article 2, the positions of the cartridge 19 and the airflow channel CN ​​are not limited to this. For example, the cartridge 19 may be positioned adjacent to the lower end (i.e., the upstream side) of the aerosol generating article 2, and in this case, the airflow channel CN ​​may be formed substantially in a straight line to connect the cartridge 19 to the lower end (i.e., the upstream side) of the aerosol generating article 2.

[0132] According to one embodiment, the cartridge 19 may include a storage section C0 containing aerosol-generating material, a cartridge heater 24, and / or a liquid delivery member impregnated with (containing) aerosol-generating material. The liquid delivery member is capable of being impregnated with aerosol-generating material supplied from the chamber C0. For example, the liquid delivery member may include a core material such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0133] According to one embodiment, the cartridge heater 24 can heat the aerosol-generating material contained in the cartridge 19. For example, the cartridge heater 24 may include a resistance heater and / or an induction heater.

[0134] As an example, a resistance heater may include a resistive material and can be heated as an electric current flows through it. As another example, for an induction heater, the aerosol generating device 1 may also include an induction coil (not shown) around the periphery of the induction heater. The induction heater may include an induction heating element and can generate heat based on a magnetic field generated from the induction coil (not shown). The cartridge heater 24 can be formed in a coil configuration surrounding (or winding around) the liquid delivery member and / or in contact with one side of the liquid delivery member (e.g., a patterned shape).

[0135] Unlike the case shown in the attached figures, the cartridge heater 24 may also be included in the aerosol generating device 1. For example, the cartridge heater 24 may be included inside the housing 10. In this case, the cartridge 19 can be separated from the cartridge heater 24 by removing the cartridge 19.

[0136] According to one embodiment, an aerosol can be generated based on the heating of the cartridge heater 24. For example, as the aerosol generating material impregnated in the liquid delivery member is heated by the cartridge heater 24, vapor can be generated from the aerosol generating material, and as the generated vapor mixes with external air flowing into the cartridge 19, an aerosol can be generated. The aerosol generated by the cartridge heater 24 flows into the aerosol generating article 2 through the airflow channel CN. As the aerosol passes through the aerosol generating article 2, tobacco or flavoring substances can be added to the aerosol, and the aerosol with added tobacco or flavoring substances can be inhaled into the user's mouth through one end of the aerosol generating article 2.

[0137] Figures 4a to 4e This is a diagram illustrating a smoke cartridge and aerosol generating apparatus, simply demonstrating an embodiment of a technique applicable to monitoring the remaining amount of aerosol-generating substances.

[0138] Reference Figures 4a to 4e One embodiment of the aerosol generating device 1 includes a main body 100 and a smoke cartridge 200.

[0139] The main body 100 occupies a portion of the appearance of the aerosol generating device 1. The cartridge 200 is detachably attached to a portion of the main body 100, thereby forming a portion of the appearance of the aerosol generating device 1 together with the main body 100.

[0140] The embodiments are not limited to the example where the cartridge 200 is detachably attached to the main body 100; the cartridge 200 may also be integrally formed with the main body 100. However, the following description focuses on an embodiment where the cartridge 200 is detachably attached to the main body 100, and the main body 100 and the cartridge 200 are each considered as a structure of the aerosol generating device 1. In this case, the remaining structure other than the cartridge 200 is referred to as the main body 100.

[0141] Reference Figures 4a to 4e The main body 100 includes a power supply 1100, an output unit 1400, and a connection unit 1500. At this time, the power supply 1100 and the output unit 1400 are equivalent to... Figure 1 The power supply 11 and output section 14 described herein have the same structure.

[0142] The output unit 1400 can display the remaining amount of aerosol-generating material stored in the storage unit 2100. The control unit controls the output of the output unit 1400 based on the remaining amount of aerosol-generating material. For example, the control unit controls whether the output unit 1400 or each individual output section is activated.

[0143] In this context, 'activation' means that the output unit 1400 indicates the presence of aerosol-generating substances at a specific location or area. Conversely, 'deactivation' means that the output unit 1400 indicates the absence of aerosol-generating substances at a specific location or area.

[0144] The output unit 1400 includes four output sections 1410, 1420, 1430, and 1440. Each output section 1410, 1420, 1430, and 1440 is connected to a power source 1100 and receives power from it. The user confirms the number of activated output sections 1410, 1420, 1430, and 1440 and monitors the remaining amount of aerosol-generating material stored in the storage unit 2100. According to an embodiment, the output unit 1400 is disposed within the cartridge 200, not included in the main body 100, but rather within the cartridge 200.

[0145] The connecting part 1500 is a structure that electrically connects the electrode 2500 of the cartridge 200 and the output part 1400 of the main body 100. Five connecting parts 1510, 1520, 1530, 1540, and 1550 can be configured. At this time, the cartridge 200 also has five electrodes 2510, 2520, 2530, 2540, and 2550, so that each connecting part 1510, 1520, 1530, 1540, and 1550 is connected one-to-one with each electrode 2510, 2520, 2530, 2540, and 2550.

[0146] On the other hand, the number of output sections, the number of connectors, and the number of electrodes are not limited to those shown in the figure. The number of connectors and electrodes is the same, and one fewer output section is provided. However, according to the embodiment, a greater number can be provided in order to monitor the remaining amount of aerosol-generating substances more precisely, or a smaller number can be provided if the necessity for precise monitoring decreases.

[0147] Reference Figures 4a to 4e The cartridge 200 includes a storage unit 2100 and an electrode 2500.

[0148] The storage unit 2100 is a structure used to collect and store aerosol-generating substances. The storage unit 2100 is equivalent to... Figure 2 and Figure 3 The cavity C0 described herein has the same structure.

[0149] Electrode 2500 is a structure disposed inside storage unit 2100 for detecting the remaining amount of aerosol-generating substances stored in storage unit 2100. As shown in the figure, electrode 2500 may be disposed protruding from the inner wall of storage unit 2100, but is not necessarily limited to this.

[0150] Multiple electrodes 2500 can be configured. The multiple electrodes 2500 are arranged spaced apart from each other. The more electrodes 2500 there are, the more accurate the sensing can be. That is, the amount of remaining aerosol-generating substances can be accurately sensed.

[0151] According to one embodiment, four electrodes 2510, 2520, 2530, and 2540 protruding from the inner wall or inner side of the storage unit 2100 are arranged spaced apart from each other along the length direction (e.g., the vertical direction) of the storage unit 2100. In this case, the four electrodes 2510, 2520, 2530, and 2540 have the same length and are equally spaced.

[0152] For example, the first electrode 2510 is disposed at a first distance from the bottom surface of the storage unit 2100, and the second electrode 2520 is disposed at a second distance from the bottom surface of the storage unit 2100, which is different from the first distance.

[0153] Four electrodes 2510, 2520, 2530, and 2540 can be used as working electrodes. Unlike the four electrodes 2510, 2520, 2530, and 2540, the remaining electrode, the fifth electrode 2550, can be used as a reference electrode. The four working electrodes 2510, 2520, 2530, and 2540 can each contact the aerosol generating substance according to the remaining amount of aerosol generating substance stored in the storage section 2100.

[0154] The first electrode 2510 is disposed at the uppermost position among the working electrodes 2510, 2520, 2530, and 2540. The first electrode 2510 is connected to the first connecting portion 1510. The first electrode 2510 is connected to the first output portion 1410 through the first connecting portion 1510.

[0155] The second electrode 2520 is positioned lower than the first electrode 2510. The second electrode 2520 is connected to the second connection portion 1520. The second electrode 2520 is connected to the second output portion 1420 via the second connection portion 1520.

[0156] The third electrode 2530 is positioned lower than the second electrode 2520. The third electrode 2530 is connected to the third connecting part 1530. The third electrode 2530 is connected to the third output part 1430 via the third connecting part 1530.

[0157] The fourth electrode 2540 is positioned lower than the third electrode 2530. Among the working electrodes 2510, 2520, 2530, and 2540, the fourth electrode 2540 is located at the lowest position. The fourth electrode 2540 is connected to the fourth connecting portion 1540. The fourth electrode 2540 is connected to the fourth output portion 1440 via the fourth connecting portion 1540.

[0158] The fifth electrode 2550 is positioned lower than the fourth electrode 2540. The fifth electrode 2550 is located at the lowest position among all electrodes 2500. The fifth electrode 2550 is connected to the fifth connecting part 1550. The fifth electrode 2550 is connected to the power supply 1100 via the fifth connecting part 1550.

[0159] As shown in the figure, the fifth electrode 2550 is disposed by protruding from the lower wall of the storage section 2100, but it is not limited to this. The fifth electrode 2550 may also be disposed by protruding from the inner wall of the storage section 2100 in the same manner as the other electrodes 2510, 2520, 2530, and 2540.

[0160] According to one embodiment, when the working electrodes 2510, 2520, 2530, 2540 and the reference electrode 2550 are in contact with the aerosol generating substance, current flows between the working electrodes 2510, 2520, 2530, 2540, the aerosol generating substance and the reference electrode 2550.

[0161] Specifically, a closed loop is formed, sequentially connecting the power supply 1100, the connection part 1500, the reference electrode (i.e., the fifth electrode) 2550, the aerosol generating substance, the working electrodes (i.e., the four electrodes 2510, 2520, 2530, and 2540), the connection part 1500, and the output part 1400, and then reconnecting to the power supply 1100. Current flows through this closed loop. Since there are four working electrodes (2510, 2520, 2530, and 2540), four closed loops can be formed for this path.

[0162] Therefore, the activation of the four output sections 1410, 1420, 1430, and 1440, which are connected to the respective electrodes 2510, 2520, 2530, and 2540, is determined by whether current flows through the working electrodes 2510, 2520, 2530, and 2540.

[0163] To allow current to flow through the working electrodes 2510, 2520, 2530, and 2540, and the reference electrode 2550 need to be in contact with the aerosol-generating substance. Whether or not the electrode 2500 is in contact with the aerosol-generating substance may be affected by the remaining amount of aerosol-generating substance stored in the storage section 2100. Therefore, the four output sections 1410, 1420, 1430, and 1440 can represent the remaining amount of aerosol-generating substance.

[0164] Reference Figure 4a The diagram shows the state in which the storage unit 2100 is filled with aerosol-generating material. In this state, all four working electrodes 2510, 2520, 2530, and 2540 are in contact with the aerosol-generating material, and therefore current flows through each of the working electrodes 2510, 2520, 2530, and 2540. As a result, all four output sections 1410, 1420, 1430, and 1440 are activated.

[0165] Reference Figure 4b This illustrates a state where approximately 25% of the aerosol-generating material is consumed. In this case, the first electrode 2510, located at the top, is no longer in contact with the aerosol-generating material. Consequently, no current flows through the first electrode 2510, and therefore the first output section 1410 connected to the first electrode 2510 becomes inactive.

[0166] Reference Figure 4c This illustrates a state where half of the aerosol-generating material has been consumed. In this case, the second electrode 2520, the second one from the top, is no longer in contact with the aerosol-generating material. Consequently, no current flows through the second electrode 2520, and therefore the second output section 1420 connected to the second electrode 2520 also becomes inactive.

[0167] Reference Figure 4d This shows a state where approximately 75% of the aerosol-generating material has been consumed. In this case, the third electrode 2530, the third one from the top, is no longer in contact with the aerosol-generating material. Consequently, no current flows through the third electrode 2530, and therefore the third output section 1430 connected to the third electrode 2530 also becomes inactive.

[0168] Reference Figure 4e This shows a state where approximately 90% of the aerosol-generating material is consumed. In this case, the fourth electrode 2540, the fourth one from the top, is no longer in contact with the aerosol-generating material. Consequently, no current flows through the fourth electrode 2540, and therefore the fourth output section 1440 connected to the fourth electrode 2540 also becomes inactive.

[0169] When all working electrodes 2510, 2520, 2530, and 2540 are not in contact with aerosol-generating substances, a closed loop is no longer formed, and therefore no current flows through the reference electrode 2550 under this condition.

[0170] According to one embodiment, the control unit electrically connected to the electrode 2500 monitors the remaining amount of aerosol-generating material by whether current flows through the electrode 2500, and the user can grasp the remaining amount of aerosol-generating material by whether the output unit 1400 is activated.

[0171] Furthermore, the control unit determines the remaining amount of aerosol-generating material stored in the storage unit 2100 in accordance with the signal generated from the electrode 2500, and controls the operation of the aerosol generating device 1 based on the remaining amount. At this time, the signal generated by the electrode 2500 refers to the current flowing through the electrode 2500 itself or a signal generated based on the current.

[0172] One embodiment of the aerosol generating apparatus 1 further includes a balance sensing sensor (not shown). The balance sensing sensor generates a signal in response to changes in the balance of the aerosol generating material stored in the storage unit 2100.

[0173] When the balance sensing sensor generates a signal corresponding to the signal generated at electrode 2500, the control unit determines the balance of aerosol generating material stored in storage unit 2100 based on the signal generated by the balance sensing sensor, and controls the operation of aerosol generating device 1.

[0174] As an example, one embodiment of the aerosol generating apparatus 1 includes a current sensor (not shown). The current sensor is connected to an electrode 2500 or a connection 1500. The current sensor generates a signal corresponding to the current value or current change flowing through the electrode 2500 or the connection 1500. For example, the current sensor generates a signal when current flows through the electrode 2500 or the connection 1500. In this case, the signal generated by the current sensor, i.e., the current sensor, refers to the current flowing through the current sensor itself or a current-based signal.

[0175] The control unit (not shown) determines whether current flows through the electrode 2500 based on the signal generated by the current sensor, thereby determining the remaining amount of aerosol-generating material stored in the cartridge 200.

[0176] As an example, the remaining amount of aerosol-generating material can be monitored not only by current but also by potential difference (voltage). In this case, the aerosol generating device 1 includes a potential difference sensor (voltage sensor).

[0177] One end of the potential difference sensor is connected to the reference electrode, i.e., the fifth electrode 2550 or the fifth connecting part 1550, and the other end of the potential difference sensor is connected to the working electrodes, i.e., the four electrodes 2510, 2520, 2530, and 2540 or the four connecting parts 1510, 1520, 1430, and 1540. Since there are four working electrodes 2510, 2520, 2530, and 2540, a total of four potential difference sensors can be configured, but the embodiment is not limited to the above-described number of potential difference sensors.

[0178] The voltage applied between the reference electrode 2550 and the working electrodes 2510, 2520, 2530, and 2540 changes in accordance with the remaining amount of aerosol-generating material stored in the storage unit 2100. In other words, the magnitude of the voltage detected by the potential difference sensor changes depending on whether each working electrode 2510, 2520, 2530, and 2540 is in contact with the aerosol-generating material.

[0179] For example, the magnitude of voltage can change according to a change in resistance. As another example, the magnitude of voltage can change according to a change in dielectric constant or capacitance. And yet another example, the magnitude of voltage can change according to a change in inductance.

[0180] A potential difference sensor generates a signal corresponding to the magnitude or change of voltage applied between its two terminals. In this case, the signal generated by the margin sensing sensor, i.e., the potential difference sensor, refers to the voltage applied between multiple electrodes (e.g., a working electrode and a reference electrode) or a signal generated based on the voltage itself. Alternatively, the aforementioned signal refers to the voltage applied to the potential difference sensor or a signal generated based on the voltage itself.

[0181] The control unit determines whether the electrode 2500 is in contact with the aerosol generating substance based on the signal generated by the potential difference sensor, thereby determining the remaining amount of aerosol generating substance stored in the cartridge 200.

[0182] The control unit determines the remaining amount of aerosol-generating material and controls the operation of the aerosol generating device 1. For example, the control unit controls whether the various output sections 1410, 1420, 1430, and 1440 of the output unit 1400 are activated.

[0183] Figures 5a to 5e This is a diagram of a smoke cartridge and an aerosol generating apparatus, simply illustrating another embodiment of a technique applicable to monitoring the remaining amount of aerosol-generating substances.

[0184] Reference Figures 5a to 5e Another embodiment of the aerosol generating device 1 includes a main body 100 and a smoke cartridge 300. Regarding the structure and effects of the aerosol generating device 1, [further details are needed]. Figures 4a to 4e Detailed descriptions within repeated ranges are omitted.

[0185] According to another embodiment, a plurality of electrodes 2500 protrude from the lower wall of the storage section 2100. The plurality of electrodes 2500 are arranged spaced apart from each other along a direction (e.g., horizontal) that traverses the length direction (e.g., vertical direction) of the storage section 2100. In this case, the plurality of electrodes 2500 have different lengths and are equally spaced apart.

[0186] For example, the first electrode 2510 extends a first length from the bottom surface of the storage unit 2100, and the second electrode 2520 extends a second length from the bottom surface of the storage unit 2100, which is different from the first length. The first electrode 2120 and the second electrode 2520 are spaced apart from each other in a direction that traverses the length direction of the storage unit 2100.

[0187] To minimize the portion of each electrode 2500 in contact with the aerosol-generating substance, only one end of the electrode 2500 is exposed to the aerosol-generating substance, while the remaining portion is coated with a waterproof material. Here, "one end" of the electrode 2500 refers to the end furthest from the bottom surface of the storage unit 2100. According to the accompanying drawings, the distance from the bottom surface of the storage unit 2100 to one end of each electrode 2500 can be different.

[0188] The electrode 2500 is partially protected by a waterproof coating to prevent it from coming into contact with aerosol-generating substances. The waterproof coating effectively blocks contact between the electrode 2500 and the aerosol-generating substances. This prevents noise generation when sensing the remaining amount of aerosol-generating substances.

[0189] For example, when one end of electrode 2500 is in contact with the aerosol generating substance, current flows through electrode 2500. However, when only the portion of electrode 2500 coated with waterproof material is in contact with the aerosol generating substance, electrode 2500 is not in contact with the aerosol generating substance, and therefore no current flows through electrode 2500.

[0190] In the following, "contact between electrode 2500 and aerosol generating substance" means that one end of electrode 2500, which is not coated with waterproof material and is exposed to aerosol generating substance, comes into contact with aerosol generating substance.

[0191] The first electrode 2510 is the longest among the working electrodes 2510, 2520, 2530, and 2540. The second electrode 2520 is shorter than the first electrode 2510. The third electrode 2530 is shorter than the second electrode 2520. The fourth electrode 2540 is shorter than the third electrode 2530. The reference electrode, i.e., the fifth electrode 2550, is shorter than all the working electrodes 2510, 2520, 2530, and 2540.

[0192] According to another embodiment, when the working electrodes 2510, 2520, 2530, 2540 and the reference electrode 2550 are in contact with the aerosol generating substance, a current flows between the working electrodes 2510, 2520, 2530, 2540, the aerosol generating substance and the reference electrode 2550.

[0193] Reference Figure 5a The diagram shows the state in which the storage section 2100 is filled with aerosol-generating material. In this case, all four working electrodes 2510, 2520, 2530, and 2540 are in contact with the aerosol-generating material through one end, and thus current flows through each working electrode 2510, 2520, 2530, and 2540. As a result, all four output sections 1410, 1420, 1430, and 1440 are activated.

[0194] Reference Figure 5b This illustrates a state where approximately 25% of the aerosol-generating material has been consumed. In this case, with the bottom surface of the storage unit 2100 as a reference, the liquid level of the aerosol-generating material is located lower than one end of the first electrode 2510, therefore the first electrode 2510 is no longer in contact with the aerosol-generating material. Consequently, no current flows through the first electrode 2510, and the first output section 1410 connected to the first electrode 2510 becomes inactive.

[0195] Reference Figure 5c This illustrates a state where half of the aerosol-generating material has been consumed. In this case, with the bottom surface of the storage unit 2100 as a reference, the liquid level of the aerosol-generating material is located lower than one end of the second electrode 2520, so the second electrode 2510 is no longer in contact with the aerosol-generating material. Consequently, no current flows through the second electrode 2520, and therefore the second output section 1420 connected to the second electrode 2520 is also inactive.

[0196] Reference Figure 5d This illustrates a state where approximately 75% of the aerosol-generating material has been consumed. In this case, with the bottom surface of the storage unit 2100 as a reference, the liquid level of the aerosol-generating material is located lower than one end of the third electrode 2530, therefore the third electrode 2530 is no longer in contact with the aerosol-generating material. Consequently, no current flows through the third electrode 2530, and the third output section 1430 connected to the third electrode 2530 also becomes inactive.

[0197] Reference Figure 5eThis illustrates a state where approximately 90% of the aerosol-generating material has been consumed. In this case, with the bottom surface of the storage unit 2100 as a reference, the liquid level of the aerosol-generating material is located lower than one end of the fourth electrode 2540, therefore the fourth electrode 2540 is no longer in contact with the aerosol-generating material. Consequently, no current flows through the fourth electrode 2540, and the fourth output section 1440 connected to the fourth electrode 2540 also becomes inactive.

[0198] When all working electrodes 2510, 2520, 2530, and 2540 do not generate substances with aerosols, a closed loop is no longer formed, and therefore no current flows through the reference electrode 2550 in this case.

[0199] Figures 6a to 6d This is a diagram of a smoke cartridge, simply illustrating yet another embodiment of a technique applicable to monitoring the remaining amount of aerosol-generating substances.

[0200] Reference Figures 6a to 6d Another embodiment of the aerosol generating device 1 includes a main body 100 and a smoke cartridge 300. Regarding the structure and effects of the aerosol generating device 1, for comparison with... Figures 4a to 4e Detailed descriptions within the repeated range are omitted.

[0201] The main body 100 includes an output unit 1400. The output unit 1400 performs the same function as described above. The output unit 1400 may also be configured in the cartridge 300, although it may not be included in the main body 100.

[0202] The cartridge 300 includes a storage unit 3100 and a patterned electrode 3500. The storage unit 3100 performs the same functions as described above. The patterned electrode 3500 performs... Figures 4a to 4e The diagram illustrates the structure of electrode 2500.

[0203] Figures 4a to 4e The electrodes 2500 shown are arranged in a prescribed pattern on the inner wall of the storage unit 3100. The electrodes 2500 having the prescribed pattern are referred to as patterned electrodes 3500.

[0204] Two patterned electrodes 3500 can be configured. The two patterned electrodes 3500, consisting of a first patterned electrode 3500a and a second patterned electrode 3500b, are configured as a pair. The first patterned electrode 3500a and the second patterned electrode 3500b are configured to face each other and engage. However, the first patterned electrode 3500a and the second patterned electrode 3500b do not cross each other. That is, the first patterned electrode 3500a and the second patterned electrode 3500b are not physically connected to each other. The two patterned electrodes 3500 are each electrically connected to a power supply 1100.

[0205] The electrode pattern of the patterned electrode 3500 includes vertical regions 3510a and 3510b extending along the length direction (e.g., vertical direction) of the storage unit 3100 and a plurality of horizontal regions 3520a and 3520b extending from the vertical regions 3510a and 3510b in a direction that traverses the length direction of the storage unit 3100 (e.g., horizontal direction) and spaced apart from each other.

[0206] At this time, the plurality of horizontal regions 3520a of the first patterned electrode 3500a and the plurality of horizontal regions 3520b of the second patterned electrode 3500b are alternately arranged in the length direction of the storage unit 3100.

[0207] As shown in the figure, a vertical region 3510a and seven horizontal regions 3520a are configured in the first patterned electrode 3500a. A vertical region 3510b and six horizontal regions 3520b are configured in the second patterned electrode 3500b. However, the number of horizontal regions is not limited to the number shown in the figure.

[0208] According to another embodiment, when the two patterned electrodes 3500 are in contact with the aerosol generating substance, a current flows between the first patterned electrode 3500a, the aerosol generating substance and the second patterned electrode 3500b.

[0209] Specifically, a closed loop is formed that sequentially connects the power supply 1100, the vertical region 3510a of the first patterned electrode 3500a, the horizontal region 3520a of the first patterned electrode 3500a, the aerosol generating substance, and the vertical region 3510b of the second patterned electrode 3500b, and is then connected to the power supply 1100 again, through which current flows.

[0210] Similarly, a closed loop is formed that sequentially connects the power supply 1100, the vertical region 3510a of the first patterned electrode 3500a, the aerosol generating substance, the horizontal region 3520b of the second patterned electrode 3500b, and the vertical region 3510b of the second patterned electrode 3500b, and is again connected to the power supply 1100, thereby allowing current to flow through the closed loop.

[0211] As shown in the figure, there are 7 horizontal regions 3520a of the first patterned electrode 3500a and 6 horizontal regions 3520b of the second patterned electrode 3500b. Therefore, the closed loop of this path becomes 13, but the embodiment is not limited to the situation shown in the figure.

[0212] According to yet another embodiment, at least one of the plurality of horizontal regions 3520a of the first patterned electrode 3500a and the vertical region 3510b of the second patterned electrode 3500b are respectively in contact with the aerosol generating material according to the remaining amount of aerosol generating material housed in the storage unit 3100.

[0213] When at least one of the multiple horizontal regions 3520a of the first patterned electrode 3500a and the vertical region 3510b of the second patterned electrode 3500b are in contact with the aerosol generating substance, current flows between at least one of the multiple horizontal regions 3520a of the first patterned electrode 3500a, the aerosol generating substance, and the vertical region 3510b of the second patterned electrode 3500b.

[0214] At this time, the activation or deactivation of the output section of the output section 1400 connected to each horizontal region 3520a and 3520b is determined based on whether current flows through the horizontal regions 3520a and 3520b.

[0215] For current to flow through horizontal regions 3520a and 3520b, these regions need to come into contact with the aerosol-generating substance. Whether or not the horizontal regions 3520a and 3520b come into contact with the aerosol-generating substance is affected by the remaining amount of aerosol-generating substance stored in the storage unit 3100. Therefore, the output unit 1400 indicates the remaining amount of aerosol-generating substance.

[0216] Reference Figure 6a This shows the state in which the storage section 3100 is filled with aerosol-generating material. In this case, all horizontal regions 3520a and 3520b are in contact with the aerosol-generating material, and therefore current flows through each horizontal region 3520a and 3520b. As a result, all output sections of the output section 1400 can be activated.

[0217] Reference Figure 6b This illustrates a state where approximately 30% of the aerosol-generating material is consumed. In this case, the five horizontal regions 3521a, 3521b, 3522a, 3522b, and 3523a from the top are no longer in contact with the aerosol-generating material. Consequently, no current flows through the five horizontal regions 3521a, 3521b, 3522a, 3522b, and 3523a, and therefore, the five output sections from the top of the fourteen output sections of the output section 1400 become inactive.

[0218] Reference Figure 6c This illustrates a state where approximately 60% of the aerosol-generating material is consumed. In this case, the five horizontal regions 3521a, 3521b, 3522a, 3522b, and 3523a, which are no longer in contact with the aerosol-generating material, and the three horizontal regions 3523b, 3524a, and 3524b located below them, also cease to be in contact with the aerosol-generating material. Consequently, no current flows through the three horizontal regions 3523b, 3524a, and 3524b, and therefore, eight of the fourteen output sections of the output section 1400, starting from the top, become inactive.

[0219] Reference Figure 6d This shows a state where approximately 85% of the aerosol-generating material is consumed. In this case, the eight horizontal regions 3521a, 3521b, 3522a, 3522b, 3523a, 3523b, 3524a, and 3524b, which are no longer in contact with the aerosol-generating material, and the five horizontal regions 3525a, 3525b, 3526a, 3526b, and 3527a located below them, are also no longer in contact with the aerosol-generating material. Consequently, no current flows through any of the horizontal regions 3520a and 3520b, and therefore, 13 of the 14 output sections of the output section 1400, starting from the top, become inactive.

[0220] Even when no current flows through any of the horizontal regions 3520a and 3520b, a vertical region 3510a, sequentially connected to the power supply 1100, the first patterned electrode 3500a, the aerosol generating material, and the second patterned electrode 3500b, is formed below the lowest horizontal region 3527a, and a closed loop is formed connecting to the power supply 1100, allowing current to flow. Thus, the lowest output section among the 14 output sections of the output section 1400 remains activated.

[0221] Although not shown, when the storage section 3100 does not contain aerosol-generating material, the entire area of ​​the two patterned electrodes 3500 is not in contact with the aerosol-generating material. In this case, a closed loop is no longer formed, and therefore no current flows through the two patterned electrodes 3500. Consequently, all output sections of the output section 1400 become inactive.

[0222] In another embodiment, the aerosol generating apparatus 1 also includes a current sensor (not shown). The current sensor is connected to the patterned electrode 3500. The current sensor generates a signal corresponding to the current value or change in current flowing through the patterned electrode 3500. For example, the current sensor generates a signal when current flows through a region of the patterned electrode 3500. In this case, the signal generated by the current sensor refers to the current flowing through the current sensor itself or a signal generated based on the current.

[0223] The control unit (not shown) determines whether current flows through a region of the patterned electrode 3500 based on a signal generated from a current sensor, thereby determining the remaining amount of aerosol-generating material stored in the cartridge 300.

[0224] On the other hand, according to yet another embodiment, the remaining amount of aerosol-generating material is monitored not only by current but also by potential difference (voltage). In this case, the aerosol generating device 1 includes a potential difference sensor (voltage sensor).

[0225] For example, one end of the potential difference sensor is connected to the horizontal region 3520a of the first patterned electrode 3500a, and the other end of the potential difference sensor is connected to a region of the vertical region 3510b of the second patterned electrode 3500b located at the same height on the bottom surface of the storage unit 3100.

[0226] As another example, one end of the potential difference sensor is connected to the horizontal region 3520b of the second patterned electrode 3500b, and the other end of the potential difference sensor is connected to a region of the vertical region 3510a of the first patterned electrode 3500a located at the same height on the bottom surface of the self-storage unit 3100.

[0227] There are 13 horizontal regions 3520a and 3520b of the patterned electrode 3500, so a total of 13 potential difference sensors are configured. The embodiment does not limit the number of the above potential difference sensors.

[0228] The voltage applied between the horizontal regions 3520a and 3520b and one of the vertical regions 3510a and 3510b at the same height changes in accordance with the remaining amount of aerosol-generating material stored in the storage unit 3100. In other words, the magnitude of the voltage detected by the potential difference sensor changes depending on whether one of the horizontal regions 3520a and 3520b and one of the vertical regions 3510a and 3510b at the same height is in contact with the aerosol-generating material.

[0229] The potential difference sensor generates a signal corresponding to the magnitude or change of the voltage applied to its two ends. In this case, the signal generated by the margin sensing sensor, i.e., the potential difference sensor, refers to the voltage itself or a voltage-based signal generated between the multiple patterned electrodes (e.g., a horizontal region of a first patterned electrode and a portion of a vertical region of a second patterned electrode located at the same height thereon). Alternatively, the aforementioned signal refers to the voltage applied to the potential difference sensor itself or a voltage-based signal generated thereon.

[0230] The control unit determines whether a region of the patterned electrode 3500 is in contact with the aerosol generating substance based on the signal generated by the potential difference sensor, thereby determining the remaining amount of aerosol generating substance stored in the cartridge 300.

[0231] The control unit determines the remaining amount of aerosol-generating material and controls the operation of the aerosol generating device 1. For example, the control unit controls whether each output section of the output unit 1400 is activated.

[0232] Figure 7 This is a cross-sectional view of a smoke cartridge, which is yet another example of a technology applicable to monitoring the remaining amount of aerosol-generating substances.

[0233] Reference Figure 7 Another embodiment of the cartridge 400 includes a storage unit 4100, an atomizing unit 4200, an electrode 4500, and a moving part 4600.

[0234] The storage unit 4100 performs the same functions as described above, so a detailed explanation of this is omitted.

[0235] The atomizing unit 4200 is disposed at the lower part of the storage unit 4100, and generates aerosols from aerosol generating substances flowing out of the storage unit 4100. An aerosol refers to a suspension of liquid and / or solid fine particles dispersed in a gas. Therefore, the aerosol generated from the atomizing unit 4200 refers to a mixture of vaporized particles generated from the aerosol generating substance and air.

[0236] The atomizing unit 4200 can convert the phase of the aerosol generating substance into a gaseous phase through vaporization and / or sublimation. For example, the atomizing unit 4200 can atomize liquid and / or solid phase aerosol generating substances into fine particles and release them to generate aerosols.

[0237] Specifically, the atomizing section 4200 includes a core material 4210 and a heating element 4220. At this time, the core material 4210 and the heating element 4220 are respectively connected to... Figure 2 and Figure 3 The liquid delivery unit and the smoke cartridge heater 24 are the same or similar.

[0238] The core material 4210 receives and absorbs aerosol-generating substances from the storage section 4100. The aerosol-generating substances absorbed by a portion of the core material 4210 move to other parts of the core material 4210 due to capillary action. For example, the core material 4210 absorbs aerosol-generating substances flowing out of the storage section 4100 through both ends, and the absorbed aerosol-generating substances move towards the center of the core material 4210. In this way, the core material 4210 transfers the aerosol-generating substances to the heating element 4220.

[0239] Heating element 4220 is a structure used to atomize the aerosol-generating substance absorbed by the core material 4210. For example, heating element 4220 heats the aerosol-generating substance to generate an aerosol.

[0240] However, the method by which the heating element 4220 atomizes the aerosol is not limited to the 'heating' method, depending on the name of the heating element 4220. As another example, the heating element 4220 could be an ultrasonic transducer that generates aerosols from aerosol-generating substances using ultrasonic vibration. Ultrasonic vibration refers to the method of generating aerosols by atomizing aerosol-generating substances using ultrasonic vibrations generated by a transducer.

[0241] As shown in the figure, the heating element 4220 can be attached to the core material 4210 in a patterned form. In this case, the heating element 4220 is permanently or reversibly attached to the core material 4210 by means of coating, spraying, vapor deposition, gold plating, impregnation, painting, printing, 3D printing, or the use of appliances.

[0242] However, the method of arranging the heating element 4220 on the core material 4210 is not limited to this. As another example, the heating element 4220 may be combined according to structural features, such as by winding it into the core material 4210. As yet another example, the heating element 4220 may be arranged on the core material 4210 during the manufacturing process by means of sintering the heating element 4220 together with the core material 4210.

[0243] On the other hand, under normal circumstances, when the heating element 4220 includes the heating area 4221, the power connection area 4222a, and 4222b, the heating element 4220 of the tobacco cartridge 400 in this embodiment includes the heating area 4221, the power connection area 4222a, 4222b, and the electrode connection area 4223a, 4223b.

[0244] Heating region 4221 is the region where the aerosol-generating substance absorbed by the core material 4210 is heated. The shape of heating region 4221 is not limited to that shown in the attached figures. Power connection regions 4222a and 4222b represent the two ends of heating region 4221 and are regions connected to terminals for receiving power from the power supply of the aerosol generating device.

[0245] Electrode connection regions 4223a and 4223b are regions connected to the electrodes 4500 disposed in the storage unit 4100. Electrode connection regions 4223a and 4223b extend from the heating region 4221 or the power connection regions 4222a and 4222b, along the core material 4210 and toward the storage unit 4100. The shape of the electrode connection regions 4223a and 4223b is not limited to the shape shown in the figure.

[0246] Electrode 4500, which is used in the same way as described above to detect the remaining amount of aerosol-generating material stored in storage unit 4100, is disposed on the inner wall of storage unit 4100. Specifically, electrode 4500 includes a first region extending along the length direction (e.g., z-axis direction) of storage unit 4100 and disposed on the inner sidewall of storage unit 4100, and a second region extending along the direction transverse to the length direction of storage unit 4100 (e.g., Y-axis direction) and disposed on the bottom surface of storage unit 4100.

[0247] Two electrodes 4500 are configured as a pair, and the two electrodes 4500 are arranged opposite each other through a first region. The two electrode connection regions 4223a and 4223b of the heating element 4220 are respectively connected to the second regions of the different electrodes 4500.

[0248] The movable component 4600 is a conductive object that can move along the length of the storage unit 4100, corresponding to the remaining amount of aerosol-generating material stored in the storage unit 4100. For example, the movable component 4600 is disposed inside the storage unit 4100 and suspended above the aerosol-generating material.

[0249] As the aerosol-generating material flows out of the storage unit 4100, the distance from the bottom surface of the storage unit 4100 to the liquid surface of the aerosol-generating material decreases, and consequently, the distance from the bottom surface of the storage unit 4100 to the moving member 4600 also decreases. Based on this principle, the moving member 4600 moves along the length direction (e.g., the z-axis direction) of the storage unit 4100.

[0250] A movable component 4600 is positioned between a pair of electrodes 4500. Both ends of the movable component 4600 are in contact with the pair of electrodes 4500. This forms a closed loop that sequentially connects the heating element 4220, one electrode 4500, the movable component 4600, the other electrode 4500, and back to the heating element 4220. Current flows through this closed loop.

[0251] At this time, even if the moving part 4600 moves along the length of the storage section 4100, it can maintain contact with the electrode 4500. Therefore, even if the liquid level of the aerosol generating substance drops due to its consumption, current flows through the pair of electrodes 4500 and the moving part 4600.

[0252] As the liquid level of the aerosol-generating substance decreases, the moving part 4600 descends, and the portion where the electrode 4500 contacts the two ends of the moving part 4600 (hereinafter referred to as the contact portion) also gradually descends. At this time, with the contact portion as a reference, the lower region is included in the closed loop and current flows through it, but the upper region does not form a closed loop because there is no aerosol-generating substance, so no current may flow through it.

[0253] As the aerosol-generating substances are consumed, the lower region decreases and the upper region increases, based on the contact area. Consequently, the area where current flows through electrode 4500 gradually decreases, while the area where no current flows gradually increases.

[0254] When electrode 4500 is considered as a resistor, as the area through which current flows gradually decreases, the length of the resistor becomes shorter, and therefore the resistance value decreases. At this point, when a potential difference sensor (not shown) is connected to the connection areas 4223a and 4223b of the two electrodes and the voltage is measured, the voltage increases due to the decreased resistance value.

[0255] As a result, as the aerosol-generating material is consumed, the position of the moving part 4600 changes, and the voltage applied to the electrode 4500 changes according to the position of the moving part 4600.

[0256] When monitoring such voltage changes, the control unit (not shown) determines the extent to which aerosol-generating substances are consumed. In other words, the control unit monitors the remaining amount of aerosol-generating substances using a potential difference sensor.

[0257] Figure 8a and Figure 8b This is a cross-sectional view of a cigarette cartridge from another embodiment where the heating temperature is adjusted based on the remaining amount of aerosol-generating material.

[0258] Reference Figure 8a and Figure 8b Another embodiment of the e-cigarette cartridge 500 includes a storage unit 5100 and an atomizing unit 5200. Detailed descriptions of the structure and effects of the e-cigarette cartridge 500, where repetition is required, are omitted.

[0259] According to yet another embodiment, the control unit of the aerosol generating device controls the atomizing unit 5200 based on the remaining amount of aerosol generating material stored in the cartridge 500. Specifically, the control unit adjusts the heating temperature of the heating element 5220 disposed on the core material 5210. Thus, the control unit adjusts the atomization amount of aerosol generated by the heating element 5220 based on the remaining amount of aerosol generating material.

[0260] Reference Figure 8a and Figure 8b The heating element 5220 of the first-state cartridge 500, which stores more aerosol-generating substances, is heated to a higher temperature than the heating element 5220 of the second-state cartridge 500.

[0261] Under normal circumstances, the more aerosol-generating material stored in the storage section 5100 is consumed, the less pressure is applied to the bottom surface of the storage section 5100 by the aerosol-generating material, and therefore the amount of aerosol-generating material flowing out of the storage section 5100 per unit time decreases. As a result, since the amount of aerosol-generating material supplied to the core material 5210 decreases, the amount of aerosol generated by the heating element 5220 also decreases.

[0262] At this point, by increasing the heating temperature of heating element 5220, the atomization of the aerosol-generating substances absorbed by core material 5210 can be promoted. Therefore, the difference in atomization amount when heated at temperature T1 in the first state with relatively large margin and when heated at a higher temperature T2 in the second state with relatively small margin is not significant.

[0263] Therefore, even as the remaining amount of aerosol-generating substances gradually decreases, the 500 cartridge can maintain the atomization volume at the prescribed level. Users of the 500 cartridge can inhale the prescribed amount of aerosol regardless of when they smoke.

[0264] Figure 9a and Figure 9b This is a cross-sectional view of a cigarette cartridge, which is another embodiment of a cartridge in which the open area of ​​the outlet is adjusted according to the remaining amount of aerosol-generating material.

[0265] Reference Figure 9a and Figure 9b Another embodiment of the cartridge 500 includes a storage unit 5100, an atomizing unit 5200, and a valve 5300. Detailed descriptions of the structure and effects of the cartridge 500, where repetition is required, will be omitted.

[0266] Valve 5300 is a structure that opens and closes the storage section 5100. Specifically, it is located at the outlet of the storage section 5100 to open and close the outlet. Thus, valve 5300 regulates the amount of aerosol-generating substance flowing out through the outlet of the storage section 5100. One or more valves 5300 are arranged corresponding to the number of outlets formed in the storage section 5100.

[0267] According to yet another embodiment, the control unit of the aerosol generating device adjusts the opening degree of the outlet based on the remaining amount of aerosol generating material stored in the cartridge 500. Specifically, the control unit controls the valve 5300 disposed at the outlet.

[0268] Reference Figure 9a and Figure 9b The outlet of the first-state cartridge 500, which stores relatively more aerosol-generating substances, is larger than the outlet of the second-state cartridge 500.

[0269] As explained above, the more aerosol-generating substances stored in the storage unit 5100 are consumed, the less aerosol-generating substances flow out of the storage unit 5100 per unit time. Therefore, the amount of aerosol generated also decreases.

[0270] At this time, the control valve 5300 opens the outlet wider, thereby increasing the supply of aerosol-generating material to the core material 5210. For example, in the first state with a relatively large margin, the opening degree of the outlet is reduced, and in the second state with a relatively small margin, the opening degree of the outlet is increased, so that even if the margin of aerosol-generating material changes, the amount of aerosol-generating material supplied to the core material 5210 can be maintained at a specified level. Therefore, the difference in atomization amount between the first state with a relatively large margin and the second state with a relatively small margin is not significant.

[0271] Therefore, even as the remaining amount of aerosol-generating substances gradually decreases, the 500 cartridge can maintain the atomization volume at the specified level. Users of the 500 cartridge can inhale the prescribed amount of aerosol regardless of when they smoke.

[0272] Figure 10 This is an exploded perspective view of a cartridge containing three aerosol-generating substances, representing yet another embodiment.

[0273] Reference Figure 10 Another embodiment of the e-cigarette cartridge 600 includes a storage unit 6100, an atomizing unit 6200, a channel component 6400, and a receiving unit 6500. Detailed descriptions of the structure and effects of the e-cigarette cartridge 600, where repetition is required, are omitted.

[0274] The storage unit 6100 includes multiple storage spaces. These storage spaces are divided by partition walls. Each storage space stores different types of aerosol-generating substances. These different types of aerosol-generating substances are separated by partition walls, thus existing independently within the storage unit 6100 without mixing.

[0275] According to yet another embodiment, the lower part of the storage unit 6100 is open. In this case, the channel member 6400 is disposed at the lower part of the storage unit 6100 and blocks at least a portion of the storage unit 6100. However, according to another embodiment, the lower part of the storage unit 6100 is blocked, and one or more outlets are disposed on the bottom surface of the storage unit 6100.

[0276] The channel component 6400 is a structure that houses one or more valves (not shown). The valves move within the channel component 6400. The channel component 6400 guides the movement of the valves.

[0277] The channel component 6400 includes a housing 6410 that forms the exterior of the channel component 6400 and multiple openings 6420 for aerosol generating substances respectively housed in multiple storage spaces to pass through.

[0278] The housing 6410 includes an internal empty space. Multiple valves are housed within this empty space and are movable. The opening degree of the opening 6420 is adjusted according to the movement of the valves.

[0279] The number of openings 6420 is the same as the number of storage spaces. Each opening 6420 is fluidly connected to its corresponding storage space. Here, 'fluidly connected' means connecting elements in a manner that allows fluid to flow through.

[0280] When multiple openings 6420 are configured, the multiple openings 6420 are configured to be spaced apart from each other, so that the different aerosol generating substances flowing out from each storage space will not be mixed during the passage of the channel component 6400, and will move through the openings 6420 connected to each storage space.

[0281] The aerosol-generating material passing through the channel component 6400 reaches the atomizing unit 6200. Specifically, the aerosol-generating material is absorbed by the core material 6210. Different aerosol-generating materials supplied to the core material 6210 are mixed in the core material 6210. One or more aerosol-generating materials are atomized into aerosols by the heating element 6220 disposed in the core material 6210.

[0282] The core material 6210 is attached to the lower part of the channel component 6400 so that all aerosol-generating substances passing through the channel component 6400 are supplied to the core material 6210. The core material 6210 attached to the lower part of the channel component 6400 can block the opening 6420. Thus, the aerosol-generating substances flowing out through the opening 6420 are directly supplied to the core material 6210. In this case, the heating element 6220 is disposed on the other side of the core material 6210 opposite to the side of the core material 6210 that is in contact with the channel component 6400.

[0283] On the other hand, in this embodiment, the core material 6210 is not limited to being bonded to the lower part of the channel member 6400. As another example, the core material 6210 is disposed spaced apart from the channel member 6400. However, in such a case, the core material 6210 has a suitable shape so that all aerosol-generating substances through the channel member 6400 are supplied to the core material 6210.

[0284] The storage section 6500 is integrated with the storage section 6100, together forming the appearance of the cartridge 600. The storage section 6500 houses the atomizing section 6200 and the channel component 6400. With the atomizing section 6200 and the channel component 6400 housed in the storage section 6500, the storage section 6500 is integrated with the storage section 6100. However, the assembly method of the cartridge 600 is not limited to this. As another example, the atomizing section 6200 and / or the channel component 6400 may also be housed in the lower part of the storage section 6100.

[0285] Although not shown, the receiving section 6500 includes an air inlet (not shown) that allows air to flow in and an aerosol outlet (not shown) for discharging the aerosol generated by the atomizing section 6200 to the outside of the cartridge 600.

[0286] Below, refer to Figure 11a and Figure 11b The following explains how the control valve adjusts the opening degree of opening 6420.

[0287] Figure 11a It is shown Figure 10 The image shows a cross-sectional view of the smoke cartridge in its first state. Figure 11b It is shown Figure 10 The image shows a cross-sectional view of the smoke cartridge in its second state.

[0288] Reference Figure 11a and Figure 11b Another embodiment of the cartridge 300 includes a valve 6300 and a channel component 6400. Detailed descriptions of the structure and effects of the cartridge 600, where repetition is required, are omitted.

[0289] The number of valves 6300 is the same as the number of storage spaces in the storage unit 6100. When multiple storage spaces are configured, multiple valves 6300 are configured in the same number. As shown, with three storage spaces, three valves 6300 can be configured, but the embodiment is not necessarily limited to the number shown.

[0290] Multiple valves 6300 are arranged around the channel component 6400. Each valve 6300 is operated rotaryly according to user input. At least a portion of each valve 6300 rotates about the central axis of the cartridge 600 in the longitudinal direction (e.g., the z-axis) to adjust the opening degree of the opening 6420. That is, the opening area of ​​the opening 6420 is adjusted by the valves 6300.

[0291] The channel component 6400 includes one or more rotating grooves 6430 formed inside the housing 6410. The rotating grooves 6430 receive valves 6300. The number of valves 6300 and rotating grooves 6430 corresponds one-to-one, forming a pair. In this embodiment, three valves 6300 and three rotating grooves 6430 are illustrated, but the number of valves 6300 and rotating grooves 6430 is not limited to this.

[0292] An opening 6420 is disposed between two rotating slots 6430. That is, the rotating slots 6430 separate the opening 6420 into multiple parts, and the number of openings 6420 is the same as the number of valves 6300 and rotating slots 6430. In other words, the number of openings 6420 is the same as the number of storage spaces. In this embodiment, three openings 6420 are configured.

[0293] Valve 6300 rotates around a predetermined axis in the circumferential direction of channel component 6400. The axis of rotation is the central axis of channel component 6400, and is spaced equidistantly from multiple openings 6420. A stopper is configured to limit the movement of valve 6300. The stopper physically separates the rotation slots 6430 and openings 6420, thus determining the range of rotational movement of valve 6300.

[0294] Reference Figure 11a The image shows the first state of the cartridge 600 with the valve 6300 fully housed in the rotating groove 6430. When the entire valve 6300 is housed in the rotating groove 6430, the open area of ​​the opening 6420 is maximized. In this case, the amount of aerosol-generating material flowing out of the storage space per unit time is maximized.

[0295] Reference Figure 11b This illustrates a second state where valve 6300 moves along the circumferential direction of channel member 6400, thereby partially receiving the cartridge 600 within the rotating groove 6430. In this state, the remaining portion of valve 6300 not received within the rotating groove 6430 blocks a portion of opening 6420, thereby affecting the opening degree of opening 6420. Figure 11a The amount of aerosol-generating material exported from the storage space per unit time is reduced compared to the first state shown. Figure 11a Compared to the previous version, it is reduced.

[0296] Although not shown in the figure, when all valves 6300 are disengaged from the rotating groove 6430, valves 6300 can block all openings 6420. In other words, when valves 6300 move along the circumferential direction of the channel member 6400, and the side of valves 6300 facing the circumferential direction of the channel member 6400 intersects with the side of opening 6420 or the stop, opening 6420 can be closed. In this case, aerosol-generating substances cannot be discharged from the storage space.

[0297] In one example, the user operates a component mechanically connected to valve 6300, thereby adjusting the opening degree of opening 6420 via valve 6300. In another example, the user operates valve 6300 to adjust the opening degree of opening 6420 via the control unit of an aerosol generating device electrically connected to valve 6300.

[0298] By adjusting the opening degree of the opening 6420, the user can regulate the amount or speed of aerosol-generating substances flowing out from the storage unit 6100. At this time, multiple valves 6300 are adjusted individually. Thus, the user can mix the aerosol-generating substances according to their own preferences and inhale the aerosol.

[0299] When the aerosol generating device has the function of monitoring the remaining amount of aerosol generating material, the control unit determines the remaining amount of aerosol generating material stored in the storage unit 6100 and operates the valve 6300 based on the remaining amount.

[0300] That is, the opening degree of the opening 6420 is adjusted in accordance with the change in the remaining amount of aerosol-generating substances. At this time, the remaining amount of aerosol-generating substances stored in the three storage spaces can be monitored separately.

[0301] On the other hand, according to the embodiment, valve 6300 may be omitted. In this case, the storage unit 6100 includes an outlet on its bottom surface that corresponds to the shape of the opening 6420. When the user rotates the storage unit 6100 relative to the channel member 6400 or rotates the channel member 6400 relative to the storage unit 6100, the outlet and the opening 6420 overlap to adjust the area from which the aerosol-generating substance flows out, thus allowing the user to adjust the opening degree of the opening 6420 in this manner.

[0302] Figure 12 This is an exploded perspective view of a cigarette cartridge, representing another embodiment capable of heating three aerosol-generating substances separately.

[0303] Reference Figure 12 Another embodiment of the e-cigarette cartridge 600 includes a storage unit 6100, an atomizing unit 6200, a channel component 6400, and a receiving unit 6500. Detailed descriptions of the structure and effects of the e-cigarette cartridge 600, where repetition is required, are omitted.

[0304] and Figure 10 Compared to the 600 shown in the image, in Figure 12 The shown cartridge 600 is equipped with multiple atomizing units 6200. As shown in the figure, it is equipped with three core materials 6210 and heating elements 6220.

[0305] Thus, the three core materials 6210 and the heating element 6220 respectively absorb different types of aerosol generating substances, thereby generating aerosols. For example, the first aerosol generating substance stored in the first storage space 6110 moves only through the first opening 6421 and is supplied only to the first core material 6211 for heating by the first heating element 6221.

[0306] Similarly, the second aerosol generating substance stored in the second storage space 6120 moves only through the second opening 6422 and is supplied only to the second core material 6212 for heating by the second heating element 6222.

[0307] Therefore, the storage space, opening 6420, core material 6210, and heating element 6220 are arranged in a row along the length direction (e.g., the z-axis direction) of the cartridge 600. For example, the third storage space 6130 storing the third aerosol generating substance, the third opening 6423, the third core material 6213, and the third heating element 6223 are arranged in a row.

[0308] The aerosol-generating material mixed with the channel component 6400 in the core material 6210 Figure 10 Unlike the embodiments, in Figure 12 In this embodiment, different types of aerosol generating substances do not mix with each other before being atomized into aerosols. The aerosols generated from these different types of aerosol generating substances are mixed inside the receiving unit 6500 and inhaled by the user.

[0309] Therefore, when aerosol-generating substances are mixed together, problems that may occur during atomization into aerosols can be prevented. For example, it can prevent the problem of unexpected changes in taste when aerosol-generating substances are mixed together. As another example, it can prevent the problem of taste deterioration caused by changes in composition due to chemical reactions between aerosol-generating substances.

[0310] The e-cigarette cartridge and the aerosol generating apparatus including the e-cigarette cartridge according to the embodiment can provide information about the remaining amount of aerosol-generated article stored in the e-cigarette cartridge, thereby improving ease of use.

[0311] Furthermore, according to the embodiment, the e-cigarette cartridge and the aerosol generating device including the e-cigarette cartridge can maintain a predetermined atomization amount even if the remaining amount of the aerosol generating article changes.

[0312] The embodiments of this disclosure described above, or other embodiments, are not mutually exclusive or distinct from each other. The constituent elements or functions of the embodiments of this disclosure described above, or other embodiments, can be used together or combined with each other.

[0313] For example, this means that component A illustrated in a particular embodiment and / or drawing can be combined with component B illustrated in other embodiments and / or drawings. That is, this means that even if the combination between components is not directly described, they can be combined except where it is stated that combination is impossible.
