In one embodiment, the aerosol-generating device 10 may be composed of only a main body. In this case, the components included in the aerosol-generating device 10 may be located in the main body. In another embodiment, the aerosol-generating device 10 may be comprised of a cartridge and a body containing an aerosol-generating substance. In this case, the components included in the aerosol-generating device 10 may be located in at least one of the body or the cartridge.

The communication interface 11 may include at least one communication module for communicating with external devices and/or networks. For example, the communication interface 11 may include a communication module for wired communication, such as a Universal Serial Bus (USB). For example, the communication interface 11 may comprise a communication module for wireless communication, such as wireless fidelity (Wi-Fi), bluetooth Low Energy (BLE), zigBee, or Near Field Communication (NFC).

The input/output interface 12 may include an input device (not shown) for receiving commands from a user and/or an output device (not shown) for outputting information to a user. For example, the input device may include a touch panel, physical buttons, a microphone, and the like. For example, the output device may include: display means for outputting visual information, such as a display or a Light Emitting Diode (LED); audio means for outputting audible information, such as a speaker or buzzer; a motor for outputting haptic information, such as haptic effects, etc.

The input/output interface 12 may transmit data corresponding to a command entered by a user through the input device to another component (or other component) of the aerosol-generating device 10. The input/output interface 12 may output information corresponding to data received from another component (or other component) of the aerosol-generating device 10 through an output device.

The aerosol-generating module 13 may generate an aerosol from an aerosol-generating substance. Here, the aerosol-generating substance may be a substance in a liquid, solid or gel state capable of generating an aerosol, or a combination of two or more aerosol-generating substances.

According to one embodiment, the liquid aerosol-generating substance may be a liquid comprising tobacco material having volatile tobacco flavour components. According to another embodiment, the liquid aerosol-generating substance may be a liquid comprising a non-tobacco material. For example, the liquid aerosol-generating substance may include water, solvents, nicotine, plant extracts, flavors, flavoring agents, vitamin mixtures, and the like.

The solid aerosol-generating substance may comprise a solid material based on a tobacco raw material, such as reconstituted tobacco sheet, cut filler or particulate tobacco. In addition, the solid aerosol-generating substance may comprise a solid material having a taste controlling agent and a flavouring material. For example, the taste control agent may include calcium carbonate, sodium bicarbonate, calcium oxide, and the like. For example, the flavoring material may comprise natural materials such as herbal granules, or may comprise materials containing aromatic components such as silica, zeolite or dextrin.

In addition, the aerosol generating substance may also include an aerosol former, such as glycerol or propylene glycol.

The aerosol-generating module 13 may comprise at least one heater (not shown).

The aerosol-generating module 13 may comprise a resistive heater. For example, the resistive heater may include at least one conductive trace. The resistive heater may be heated when current flows through the conductive trace. At this time, the aerosol-generating substance may be heated by a heated resistance heater.

The conductive trace may include a resistive material. In one example, the conductive trace may be formed from a metallic material. In another example, the conductive trace may be formed from a ceramic material, carbon, a metal alloy, or a composite of a ceramic material and a metal.

The resistive heater may include conductive traces formed in any of a variety of shapes. For example, the conductive trace may be formed in any one of a tubular shape, a plate shape, a needle shape, a rod shape, and a coil shape.

The aerosol-generating module 13 may comprise a heater using an induction heating method. For example, the induction heater may comprise an electrically conductive coil. By adjusting the current flowing through the conductive coil, the induction heater can generate an alternating magnetic field whose direction is periodically changed. At this time, when an alternating magnetic field is applied to the magnet, energy loss may occur in the magnet due to eddy current loss and hysteresis loss. In addition, the lost energy may be released as thermal energy. Thus, the aerosol-generating substance located in the vicinity of the magnet may be heated. Here, the object generating heat due to the magnetic field may be referred to as a susceptor.

Meanwhile, the aerosol-generating module 13 may generate ultrasonic vibrations to generate an aerosol from the aerosol-generating substance.

The aerosol generating device 10 may be referred to as a cartomizer (cartomizer), a nebulizer (atomizer), or a vaporizer (vaporizer).

The memory 14 may store a program for processing and controlling each signal in the controller 17. The memory 14 may store processed data and data to be processed.

For example, the memory 14 may store applications designed to perform various tasks that may be handled by the controller 17. The memory 14 may selectively provide some of the stored applications in response to a request from the controller 17.

For example, the memory 14 may store data regarding an operation time of the aerosol-generating device 10, a maximum number of puffs, a current number of puffs, a number of uses of the battery 16, at least one temperature profile, a user's inhalation pattern, and data regarding charge/discharge. Here, "suction" refers to inhalation by the user. "inhalation" refers to the act of drawing air or other substances into the user's mouth, nasal cavity, or lungs through the user's mouth or nose.

The memory 14 may include at least one of volatile memory (e.g., dynamic Random Access Memory (DRAM), static Random Access Memory (SRAM), or Synchronous Dynamic Random Access Memory (SDRAM)), non-volatile memory (e.g., flash memory), a Hard Disk Drive (HDD), or a Solid State Drive (SSD).

The sensor module 15 may include at least one sensor.

For example, the sensor module 15 may include a sensor for sensing suction (hereinafter referred to as a "suction sensor"). In this case, the suction sensor may be implemented as a proximity sensor, such as an IR sensor, a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.

For example, the sensor module 15 may include a sensor for sensing suction (hereinafter referred to as a "suction sensor"). In this case, the suction sensor may be implemented by a pressure sensor, a gyro sensor, an acceleration sensor, a magnetic field sensor, or the like.

For example, the sensor module 15 may include a sensor (hereinafter referred to as "temperature sensor") for sensing the temperature of the heater included in the aerosol-generating module 13 and the temperature of the aerosol-generating substance. In this case, the heater included in the aerosol-generating module 13 may also be used as a temperature sensor. For example, the resistive material of the heater may be a material having a predetermined temperature coefficient of resistance. The sensor module 15 may measure the resistance of the heater according to the temperature change, thereby sensing the temperature of the heater.

For example, in the case where the body of the aerosol-generating device 10 is formed to allow insertion of a rod therein, the sensor module 15 may include a sensor for sensing insertion of the rod (hereinafter referred to as a "rod detection sensor").

For example, in the case where the aerosol-generating device 10 includes a cartridge, the sensor module 15 may include a sensor for sensing the attachment/detachment of the cartridge and the position of the cartridge (hereinafter referred to as "cartridge detection sensor").

In this case, the rod detection sensor and/or the cartridge detection sensor may be implemented as an inductance-based sensor, a capacitance sensor, a resistance sensor, or a hall sensor (or hall IC) using the hall effect.

For example, the sensor module 15 may include a voltage sensor for sensing a voltage applied to a component (e.g., the battery 16) provided in the aerosol-generating device 10 and/or a current sensor for sensing a current.

The battery 16 may supply power for operating the aerosol-generating device 10 under the control of the controller 17. The battery 16 may supply power to other components disposed in the aerosol-generating device 10. For example, the battery 16 may supply power to a communication module included in the communication interface 11, an output device included in the input/output interface 12, and a heater included in the aerosol generating module 13.

The battery 16 may be a rechargeable battery or a disposable battery. For example, the battery 16 may be a lithium-ion (Li-ion) battery or a lithium polymer (Li-polymer) battery. However, the present disclosure is not limited thereto. For example, when the battery 16 is rechargeable, the charge rate (C-rate) of the battery 16 may be 10C, and the discharge rate (C-rate) thereof may be 10C to 20C. However, the present disclosure is not limited thereto. Further, for stable use, the battery 16 may be manufactured such that 80% or more of the total capacity can be ensured even when 2000 charge/discharge is performed.

The aerosol generating device 10 may also include a Protection Circuit Module (PCM) (not shown), which is a circuit for protecting the battery 16. A Protection Circuit Module (PCM) may be disposed adjacent to an upper surface of the battery cell 16. For example, in order to prevent overcharge and overdischarge of the battery 16, when an overvoltage is applied to the battery 16 when a short circuit occurs in a circuit connected to the battery 16, or when an overcurrent flows through the battery 16, a Protection Circuit Module (PCM) may cut off an electrical path to the battery 16.

The aerosol generating device 10 may further comprise a charging terminal to which electric power supplied from the outside is input. For example, the charging terminal may be formed at one side of the main body of the aerosol-generating device 10. The aerosol generating device 10 may charge the battery 16 using the electric power supplied through the charging terminal. In this case, the charging terminal may be configured as a wired terminal for USB communication, pogo pin, or the like.

The aerosol-generating device 10 may further comprise a power terminal (not shown) to which power supplied from the outside is input. For example, the power line may be connected to a power terminal provided at one side of the main body of the aerosol-generating device 10. The aerosol-generating device 10 may charge the battery 16 using electric power supplied through a power line connected to the power terminal. In this case, the power terminal may be a wired terminal for USB communication.

The aerosol-generating device 10 may wirelessly receive power supplied from the outside through the communication interface 11. For example, the aerosol-generating device 10 may wirelessly receive power using an antenna included in a communication module for wireless communication. The aerosol generating device 10 may charge the battery 16 using wirelessly supplied power.

The controller 17 may control the overall operation of the aerosol-generating device 10. The controller 17 may be connected to each component provided in the aerosol-generating device 10. The controller 17 may send and/or receive signals to and/or from each component to control the overall operation of each component.

The controller 17 may include at least one processor. The controller 17 may use a processor included therein to control the overall operation of the aerosol-generating device 10. Here, the processor may be a general-purpose processor such as a Central Processing Unit (CPU). Of course, the processor may be a special purpose device, such as an Application Specific Integrated Circuit (ASIC), or may be any other hardware-based processor.

The controller 17 may perform any of a variety of functions of the aerosol-generating device 10. For example, the controller 17 may perform any one of various functions (e.g., a warm-up function, a heating function, a charging function, and a cleaning function) of the aerosol-generating device 10 according to the state of each component provided in the aerosol-generating device 10 and a user command received through the input/output interface 12.

The controller 17 may control the operation of each component provided in the aerosol-generating device 10 based on data stored in the memory 14. For example, the controller 17 may control the supply of a predetermined amount of electric power from the battery 16 to the aerosol-generating module 13 for a predetermined time based on data about the temperature distribution, the inhalation pattern of the user, stored in the memory 14.

The controller 17 may use a suction sensor included in the sensor module 15 to determine whether suction is occurring or not. For example, the controller 17 may check the temperature change, the flow rate change, the pressure change, and the voltage change of the aerosol-generating device 10 based on the values sensed by the suction sensor. The controller 17 may determine the occurrence or non-occurrence of aspiration based on the value sensed by the aspiration sensor.

The controller 17 may control the operation of each component provided in the aerosol-generating device 10 according to the number of times that suction is or is not occurring and/or is being sucked. For example, the controller 17 may perform control such that the temperature of the heater is changed or maintained based on the temperature distribution stored in the memory 14.

The controller 17 may perform control such that the power supply to the heater is interrupted according to a predetermined condition. For example, the controller 17 may perform control such that when the stick is removed, when the cartridge is detached, when the number of times of suction reaches a predetermined maximum number of times of suction, when suction is not sensed for a predetermined period of time or more, or when the remaining capacity of the battery 16 is less than a predetermined value, power supply to the heater is interrupted.

The controller 17 may calculate the remaining capacity with respect to the full charge capacity of the battery 16. For example, the controller 17 may calculate the remaining capacity of the battery 16 based on values sensed by a voltage sensor and/or a current sensor included in the sensor module 15.

The controller 17 may perform control such that the heater is supplied with power using at least one of a Pulse Width Modulation (PWM) method or a proportional-integral-derivative (PID) method.

For example, the controller 17 may perform control such that a current pulse having a predetermined frequency and a predetermined duty ratio is supplied to the heater using a PWM method. In this case, the controller 17 can control the amount of electric power supplied to the heater by adjusting the frequency and the duty ratio of the current pulses.

For example, the controller 17 may determine the target temperature to be controlled based on the temperature distribution. In this case, the controller 17 may control the amount of electric power supplied to the heater using a PID method that is a feedback control method using a difference between the temperature of the heater and the target temperature, a value obtained by integrating the difference with respect to time, and a value obtained by differentiating the difference with respect to time.

Although the PWM method and the PID method are described as examples of a method of controlling power supply to the heater, the present disclosure is not limited thereto, and any one of various control methods, such as a proportional-integral (PI) method or a proportional-derivative (PD) method, may be employed.

Meanwhile, the controller 17 may perform control such that power is supplied to the heater according to a predetermined condition. For example, when a cleaning function for cleaning a space of an insertion rod is selected in response to a command input by a user through the input/output interface 12, the controller 17 may perform control such that a predetermined amount of power is supplied to the heater.

Fig. 2 to 4 are views for explaining an aerosol-generating device according to an embodiment of the present disclosure.

According to various embodiments of the present disclosure, the aerosol-generating device 10 may include a body 100 and/or a cartridge 200.

Referring to fig. 2, the aerosol-generating device 10 according to the embodiment may include a body 100, the body 100 being formed such that the rod 20 may be inserted into an inner space formed by the case 101.

Rod 20 may resemble a conventional combustion cigarette. For example, the rod 20 may be divided into a first portion comprising aerosol generating material and a second portion comprising a filter or the like. Alternatively, the aerosol generating material may be included in the second portion of the rod 20. For example, a flavouring substance in the form of granules or capsules may be inserted into the second portion.

The entire first portion is inserted into the insertion space of the aerosol-generating device 10, and the second portion may be exposed to the outside. Alternatively, only a part of the first portion may be inserted into the insertion space of the aerosol-generating device 10, or a part of the second portion and the first portion may be inserted. In this case, the aerosol may be generated by passing external air through the first portion, and the generated aerosol may be delivered into the mouth of the user through the second portion.

The main body 100 may be configured such that external air is introduced into the main body 100 in a state in which the stick 20 is inserted therein. In this case, the external air introduced into the main body 100 may flow into the user's mouth via the stick 20.

The heater may be provided in the body 100 at a position corresponding to a position where the rod 20 is inserted into the body 100. Although the heater is shown in the drawings as a conductive heater 110 including a pin-shaped conductive trace, the present disclosure is not limited thereto.

The heater may use power supplied from the battery 16 to heat the inside and/or outside of the wand 20. Aerosol may be generated from the heated rod 20. At this time, the user may hold one end of the rod 20 in the mouth to inhale the aerosol containing the tobacco material.

Meanwhile, the controller 17 may perform control such that power is supplied to the heater in a state in which the rod 20 is not inserted into the main body according to a predetermined condition. For example, when a cleaning function for cleaning the space of the insertion rod 20 is selected in response to a command input by the user through the input/output interface 12, the controller 17 may perform control such that a predetermined amount of power is supplied to the heater.

The controller 17 may monitor the number of puffs based on a value sensed by a puff sensor from a point in time when the wand 20 is inserted into the main body.

When the wand 20 is removed from the main body, the controller 17 may initialize the current number of puffs stored in the memory 14.

Referring to fig. 3, the aerosol-generating device 10 according to an embodiment may include a body 100 and a cartridge 200. The body 100 may support the cartridge 200, and the cartridge 200 may contain an aerosol-generating substance.

According to one embodiment, the cartridge 200 may be configured to be removably mounted to the body 100. According to another embodiment, the cartridge 200 may be integrally configured with the body 100. For example, the cartridge 200 may be mounted to the body 100 in such a manner that at least a portion of the cartridge 200 is inserted into an insertion space formed by the housing 101 of the body 100.

The main body 100 may be formed to have a structure in which external air may be introduced into the main body 100 in a state in which the cartridge 200 is inserted. Here, the external air introduced into the main body 100 may flow into the mouth of the user via the cartridge 200.

The controller 17 may use a cartridge detection sensor included in the sensor module 15 to determine whether the cartridge 200 is in the installed state or in the disassembled state. For example, the cartridge detection sensor may transmit pulsed current through a first terminal connected to the cartridge 200. In this case, the controller 17 may determine whether the cartridge 200 is in the connected state based on whether the pulse current is received through the second terminal.

The cartridge 200 may include a heater 210 configured to heat the aerosol-generating substance and/or a reservoir 220 configured to contain the aerosol-generating substance. For example, a liquid delivery element impregnated with (containing) an aerosol-generating substance may be disposed within the reservoir 220. The conductive traces of the heater 210 may be formed in a structure that wraps around the liquid transport element. In this case, when the liquid delivery element is heated by the heater 210, an aerosol may be generated. Here, the liquid transport element may comprise a core made of, for example, cotton fibers, ceramic fibers, glass fibers or porous ceramics.

The cartridge 200 may include an insertion space 230 configured to allow insertion of the rod 20. For example, the cartridge 200 may include an insertion space formed by an inner wall extending in a circumferential direction along the direction of the insertion rod 20. In this case, the insertion space may be formed by opening the inner side of the inner wall up and down. The rod 20 may be inserted into an insertion space formed by the inner wall.

The insertion space into which the rod 20 is inserted may be formed in a shape corresponding to a shape of a portion of the rod 20 inserted into the insertion space. For example, when the rod 20 is formed in a cylindrical shape, the insertion space may be formed in a cylindrical shape.

When the rod 20 is inserted into the insertion space, the outer surface of the rod 20 may be surrounded by and contact with the inner wall.

A portion of the rod 20 may be inserted into the insertion space, and the remaining portion of the rod 20 may be exposed to the outside.

A user may inhale the aerosol while biting one end of the rod 20 with the mouthpiece. The aerosol generated by the heater 210 may pass through the rod 20 and be delivered to the user's mouth. At this time, as the aerosol passes through the rod 20, the material contained in the rod 20 may be added to the aerosol. An aerosol of infusion material may be inhaled into the user's mouth through one end of the rod 20.

Referring to fig. 4, the aerosol-generating device 10 according to the embodiment may include a main body 100 supporting a cartridge 200 and a cartridge 200 containing an aerosol-generating substance. The body 100 may be formed to allow the rod 20 to be inserted into the insertion space 130 therein.

The aerosol-generating device 10 may comprise a first heater for heating the aerosol-generating substance stored in the cartridge 200. For example, when a user holds one end of the rod 20 in the mouth to inhale the aerosol, the aerosol generated by the first heater may pass through the rod 20. At this time, a fragrance may be added to the aerosol as it passes through the rod 20. The aerosol containing the fragrance may be inhaled into the user's mouth through one end of the wand 20.

Alternatively, according to another embodiment, the aerosol-generating device 10 may comprise a first heater for heating the aerosol-generating substance stored in the cartridge 200 and a second heater for heating the rod 20 inserted into the body 100. For example, the aerosol-generating device 10 may generate an aerosol by heating the aerosol-generating substance stored in the cartridge 200 and the rod 20 using the first heater and the second heater, respectively.

Fig. 5 and 6 are views for explaining a stick according to an embodiment of the present disclosure.

Referring to fig. 5, the rod 20 may include a tobacco rod 21 and a filter rod 22. The first portion described above with reference to fig. 2 may comprise a tobacco rod. The second portion described above with reference to fig. 2 may include filter rods 22.

Fig. 5 shows that the filter rod 22 comprises a single segment. However, the filter rod 22 is not limited thereto. In other words, the filter rod 22 may comprise a plurality of segments. For example, the filter rod 22 may include a first segment configured to cool the aerosol and a second segment configured to filter specific components contained in the aerosol. Moreover, the filter rod 22 may also include at least one segment configured to perform other functions, as desired.

The diameter of the rod 20 may be in the range of 5mm to 9mm, and the length of the rod 20 may be about 48mm, but the embodiment is not limited thereto. For example, the length of the tobacco rod 21 may be about 12mm, the length of the first segment of the filter rod 22 may be about 10mm, the length of the second segment of the filter rod 22 may be about 14mm, and the length of the third segment of the filter rod 22 may be about 12mm, although the embodiments are not limited in this respect.

The rod 20 may be wrapped with at least one wrapper 24. The wrapper 24 may have at least one hole through which external air may be introduced or through which internal air may be exhausted. For example, a wrapper 24 may be used to wrap the rod 20. As another example, the rod 20 may be double wrapped with at least two wraps 24. For example, the tobacco rod 21 may be wrapped with a first wrapper 241. For example, the filter rod 22 may be wrapped with wrappers 242, 243, 244. The tobacco rod 21 and filter rod 22 wrapped by the wrapper may be combined. Rod 20 may be repacked by a single wrapper 245. When each of the tobacco rod 21 and filter rod 22 includes multiple segments, each segment may be wrapped with a wrap 242, 243, 244. The entire rod 20, consisting of multiple segments wrapped by a wrapper, may be repacked by another wrapper.

The first wrapper 241 and the second wrapper 242 may be formed of a common filter wrapper. For example, the first wrapper 241 and the second wrapper 242 may be porous wrapper paper or non-porous wrapper paper. Further, the first wrapper 241 and the second wrapper 242 may be made of an oil resistant paper sheet and an aluminum laminate packaging material.

The third wrapper 243 may be made of hard wrap paper. For example, the basis weight of the third wrap 243 may be in the range of 88g/m2 to 96g/m 2. For example, the basis weight of the third wrap 243 may be in the range of 90g/m2 to 94g/m 2. Further, the total thickness of the third wrapper 243 may be in the range of 1200 μm to 1300 μm. For example, the total thickness of the third wrapper 243 may be 125 μm.

The fourth wrapper 244 may be made of oil resistant hard wrapping paper. For example, the basis weight of the fourth wrapper 244 may be in the range of about 88g/m2 to about 96g/m 2. For example, the basis weight of the fourth wrapper 244 may be in the range of 90g/m2 to 94g/m 2. Further, the total thickness of the fourth wrap 244 may be in the range of 1200 μm to 1300 μm. For example, the total thickness of the fourth wrap 244 may be 125 μm.

The fifth wrapper 245 may be made of sterile paper (MFW). Here, MFW refers to specially manufactured paper having enhanced tensile strength, water resistance, smoothness, and the like as compared to plain paper. For example, the basis weight of the fifth wrapper 245 may be in the range of 57g/m2 to 63g/m 2. For example, the basis weight of the fifth wrapper 245 may be about 60g/m2. Further, the total thickness of the fifth wrapper 245 may be in the range of 64 μm to 70 μm. For example, the total thickness of the fifth wrapper 245 may be 67 μm.

The predetermined material may be included in the fifth wrapper 245. Here, an example of the predetermined material may be, but is not limited to, silicon. For example, silicon exhibits characteristics such as heat resistance that hardly change due to temperature, oxidation resistance, resistance to various chemicals, water resistance, electrical insulation, and the like. However, any material other than silicon may be applied to (or coated on) the fifth wrapper 245 without limitation, so long as the material has the above-described characteristics.

The fifth wrapper 245 may prevent the burning of the rod 20. For example, when the tobacco rod 21 is heated by the heater 110, there is a possibility that the rod 20 burns. In detail, the rod 20 may burn when the temperature increases to a temperature above the ignition point of any of the materials contained in the tobacco rod 21. Even in this case, since the fifth wrapper 245 includes a non-combustible material, the burning of the rod 20 can be prevented.

In addition, the fifth wrapper 245 may prevent the aerosol-generating device 10 from being contaminated by the substance formed by the rod 20. By suction from the user, a liquid substance may be formed in the wand 20. For example, when the aerosol formed by the rod 20 is cooled by outside air, a liquid material (e.g., moisture, etc.) may be formed. When the fifth wrapper 245 wraps the rod 20, the liquid material formed in the rod 20 may be prevented from leaking out of the rod 20.

The tobacco rod 21 may include an aerosol generating material. For example, the aerosol-generating material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto.

For example, the thermally conductive material surrounding the tobacco rod 21 may evenly distribute the heat transferred to the tobacco rod 21, and thus, the thermal conductivity applied to the tobacco rod may be increased, and the taste of the tobacco may be improved. Moreover, the thermally conductive material surrounding the tobacco rod 21 may act as a susceptor that is heated by an induction heater. Here, although not shown in the figures, the tobacco rod 21 may include an additional susceptor in addition to the thermally conductive material surrounding the tobacco rod 21.

In addition, at least one perforation 36 may be formed in the fifth wrapper 355. For example, perforations 36 may be formed in the area of fifth wrapper 355 surrounding tobacco rod 31, but are not limited thereto. For example, the perforations 36 may transfer heat formed by the heater 210 shown in fig. 3 into the tobacco rod 31.

Likewise, second section 322 may include at least one bladder 34. Here, the pouch 34 may generate a scent. The bladder 34 may generate an aerosol. For example, the pouch 34 may have a configuration in which the liquid including the flavoring material is wrapped by a film.

Fig. 7 to 9 are diagrams for explaining a battery module of an aerosol-generating device according to an embodiment of the present disclosure.

Referring to fig. 7, the aerosol-generating device 10 may include a battery module 710, a controller 17, a heater 730, and/or a charging circuit 740.

The battery module 710 may include a battery 16 and/or a protection circuit module 711. The protection circuit module 711 may be electrically connected to the battery 16. For example, the protection circuit module 711 may be provided in contact with one side of the battery 16. The battery module 710 may be configured to be detachably mounted in the main body 100.

The protection circuit module 711 may cut off the electrical path to the battery 16 according to a predetermined standard.

The protection circuit module 711 may cut off an electrical path to the battery 16 based on the voltage of the battery 16. For example, when the level of the voltage of the battery 16 is equal to or higher than the level of the voltage corresponding to the overcharge, the protection circuit module 711 may cut off the electrical path to the battery 16. For example, when the level of the voltage of the battery 16 is lower than the level of the voltage corresponding to the overdischarge, the protection circuit module 711 may cut off the electrical path to the battery 16.

The protection circuit module 711 may cut off an electrical path to the battery 16 based on a current flowing through components included in the battery module 710. For example, when the level of the current flowing through the components included in the battery module 710 is equal to or higher than the level of the current corresponding to the overcurrent, the protection circuit module 711 may cut off the electrical path to the battery 16.

Here, the level of the voltage corresponding to the overcharge, the level of the voltage corresponding to the overdischarge, and/or the level of the current corresponding to the overcurrent may be determined according to the type of the battery 16. For example, in the case where the type of the battery 16 is a type corresponding to the first charge capacity, the level of the voltage corresponding to the overcharge may be higher than in the case where the type of the battery 16 is a type corresponding to the second charge capacity, which is smaller than the first charge capacity.

The heater 730 may be heated with power supplied from the battery 16. The switching element may be disposed between the battery module 710 and the heater 730. The switching element may be a transistor element. For example, the switching element may be implemented as a Bipolar Junction Transistor (BJT) or a Field Effect Transistor (FET). In the present disclosure, a transistor element is used as a switching element. However, the present disclosure is not limited thereto.

The controller 17 may perform control such that a current pulse having a predetermined frequency and a predetermined duty ratio is supplied to the heater using a Pulse Width Modulation (PWM) scheme. For example, the controller 17 may control the operation of the switching element according to a predetermined duty ratio to adjust the power supplied to the heater 730.

The charging circuit 740 may transmit power input from the outside. For example, the charging circuit 740 may transmit power input from the outside to the battery module 710. For example, the charging circuit 740 may transmit electric power input from the outside to the controller 17.

The charging circuit 740 may include a charging terminal to which power is input from the outside. For example, the charging circuit 740 may transmit power supplied through a power line connected to the charging terminal to the battery module 710 and/or the controller 17.

The charging circuit 740 may regulate the current and/or voltage supplied to the battery 16. For example, the charging circuit 740 may include a DC-DC converter configured to step up and/or step down an input voltage to output the input voltage. The controller 17 may control the operation of the charging circuit 740 such that a current and/or a voltage corresponding to the type of the battery 16 is supplied to the battery 16.

Referring to fig. 8 and 9, the protection circuit module 711 may include a protection Integrated Circuit (IC) 810, an identification IC 820, and/or a thermistor 830.

The protection IC 810 may control the operation of the first protection element F1 and/or the second protection element F2 based on the level of the voltage of the battery 16. For example, when the level of the voltage of the battery 16 is lower than the level of the voltage corresponding to the overdischarge, the protection IC 810 may turn off the first protection element F1 through the DO terminal. For example, when the level of the voltage of the battery 16 is equal to or higher than the level of the voltage corresponding to the overcharge, the protection IC 810 may turn off the second protection element F2 through the CO terminal.

The identification IC 820 may output a signal corresponding to the battery 16. For example, the identification IC 820 may output a signal corresponding to the battery 16 in response to supplying power to the protection circuit module 711. The signal output from the identification IC 820 may be transmitted to the controller 17.

The controller 17 may determine the type of the battery 16 based on the signal transmitted from the identification IC 820. According to one embodiment, the memory 14 may store data of the specification of the battery 16 corresponding to the type of the battery 16. Here, the specification of the battery 16 may include a charge capacity of the battery 16, an input voltage thereof, an input current thereof, an output voltage thereof, and/or an output current thereof. The controller 17 may determine a specification corresponding to the type of the battery 16 determined based on the signal transmitted from the identification IC 820 based on the data of the specification of the battery 16 stored in the memory 14.

The controller 17 may monitor the resistance value of the thermistor 830. The thermistor 830 may be an element that changes resistance according to a temperature change of the battery 16. For example, the thermistor 830 may be a Negative Temperature Coefficient (NTC) thermistor characterized by a decrease in resistance as the temperature increases.

The controller 17 may determine the temperature of the battery 16 based on the resistance value of the thermistor 830. For example, the controller 17 may determine the resistance value of the thermistor 830 as the temperature of the battery 16. For example, the controller 17 may determine the compensation result of the resistance value of the thermistor 830 according to a predetermined criterion as the temperature of the battery 16.
