Description

Technical Field

[0001] The present invention relates to an aerosol generating device including a detachable battery and a battery protection circuit separated from the battery.

Background Art

[0002] There is an increasing demand for aerosol generating devices that generate aerosols in a non-combustion manner, replacing the method of generating aerosols by burning cigarettes. An aerosol generating device is, for example, a device that generates an aerosol from an aerosol generating substance in a non-combustion manner and supplies it to a user, or performs a function of generating an aerosol having a fragrance by passing the vapor generated from the aerosol generating substance through a fragrance medium.

[0003] An aerosol generating device includes a battery for power supply and a heater that generates heat by power supply, and can generate an aerosol by heating an aerosol generating substance through the heater.

[0004] Existing aerosol generating devices generally include an integrated battery in order to reduce the overall size of the device and increase the design freedom of the device. Recently, however, research on aerosol generating devices using detachable batteries has gradually increased as an attempt to increase the usage time of aerosol generating devices and improve user convenience.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Aerosol generating devices generally use a battery pack including a battery and a battery protection circuit (or "protection circuit module (PCM)") for preventing overcharging, over-discharging or over-current of the battery.

[0006] In aerosol generators, when using a battery pack containing such a battery and battery protection circuit, even if the battery protection circuit operates normally, once the battery reaches the end of its lifespan, the only option is to replace the battery pack with a new one. In other words, even if the battery protection circuit has a longer lifespan than the battery, in aerosol generators using existing battery packs, the battery protection circuit, which is still functioning properly, must be discarded, thus increasing battery replacement costs.

[0007] Various embodiments of the present invention aim to reduce battery replacement costs and enable the use of various types of batteries for the operation of the aerosol generator by providing an aerosol generator that separates the battery and the battery protection circuit and allows the battery protection circuit to be reused even when the battery is discarded or replaced.

[0008] The problems to be solved through embodiments of the present invention are not limited to those described above, and any problems not mentioned will be clearly understood by those skilled in the art to which the embodiments belong from this specification and the accompanying drawings.

[0010] An operating method of an aerosol generator according to one embodiment may include: an operation to detect the type of battery coupled to the battery housing space of the aerosol generator based on the charging or discharging characteristics of the battery which is detachably coupled to the battery housing space of the aerosol generator; and an operation to control the charging or discharging of the battery through a battery protection circuit electrically connected to the battery when the battery is coupled to the battery housing space, based on the detected type of battery.

[0022] Regardless of the drawing reference numerals, identical or similar components are assigned the same reference numeral, and redundant explanations for them are omitted.

[0023] Figure 1 is a perspective view showing an aerosol generating apparatus according to one embodiment.

[0024] The aerosol generating device 1 can generate and provide aerosols.

[0025] The aerosol generator 1 may include a main body 10. The main body 10 forms the overall appearance of the aerosol generator 1 and may contain internal space. At least one of the following may be located inside the main body 10: an article storage section 10h, a heater (not shown), a control unit (not shown), and a battery (not shown).

[0026] The article storage section 10h can provide a space into which the aerosol product 2 can be detachably bound (inserted). The aerosol product 2 may include an aerosol-generating substance that generates an aerosol when heated by a heater. The article storage section 10h can provide a space that is open toward the outside of the main body 10 so that the aerosol product 2 can be inserted.

[0027] The article storage section 10h may be recessed inward toward the body 10 so that at least a portion of the aerosol product 2 can be inserted into it. The depth to which the article storage section 10h is recessed may correspond to the length of the region in the aerosol product 2 that contains the aerosol-generating substance and / or medium. A portion of the aerosol product 2 may be inserted into the body 10, while another portion of the aerosol product 2 may protrude outward toward the body 10. The user can inhale air containing the aerosol by putting the portion of the aerosol product 2 exposed outward toward the body 10 into their mouth.

[0028] The main body 10 may further include a cover 11 that opens or closes the article storage section 10h. The cover 11 is movably positioned on the main body 10 and may either expose the article storage section 10h to the outside of the aerosol generating device 1, or cover the article storage section 10h so that it is not exposed to the outside of the aerosol generating device 1. For example, the cover 11 can open the article storage section 10h in a first position, exposing the article storage section 10h to the outside, thereby allowing the aerosol product 2 to be inserted into the article storage section 10h. Alternatively, the cover 11 can move from the first position to a second position, closing the article storage section 10h and preventing it from being exposed to the outside, thereby protecting the article storage section 10h from external impacts or the inflow of external foreign matter.

[0029] A heater (not shown) located inside the main body 10 can heat the aerosol product 2. For example, the heater may include a tubular heating element, a plate heating element, a needle-shaped heating element, or a rod-shaped heating element. The heater may include an electrical resistance heater and / or an induction heating heater.

[0030] For example, a heater is a resistive heater. A heater includes a conductive track, and the heater can be heated by an electric current flowing through the conductive track. A heater can be electrically connected to a power source. A heater can generate heat by receiving power from the power source.

[0031] For example, the heater is a multi-heater. The heater may include a first heater and a second heater. The first heater and the second heater may be heated sequentially or simultaneously.

[0032] The aerosol generator 1 may include an induction coil. The induction coil can generate heat in a heater. The heater may include a susceptor. The susceptor can be heated by a magnetic field generated from the alternating current flowing through the induction coil. The magnetic field can penetrate the susceptor and generate eddy currents inside it. The eddy currents can generate heat in the susceptor.

[0033] As another example, a susceptor may be included inside the aerosol product 2. The susceptor inside the aerosol product 2 may be heated by the magnetic field generated from the alternating current flowing through the induction coil. The susceptor is located inside the aerosol product 2 and does not need to be electrically connected to the aerosol generating device. The susceptor may be inserted into the article containment section 10h together with the aerosol product 2 and may be removed from the article containment section 10h together with the aerosol product 2. If an alternating current flows through the induction coil, the aerosol product 2 may be heated by the susceptor inside the aerosol product 2.

[0034] The power supply can provide power to operate the components of the aerosol generator 1. The power supply is a battery that stores power. The power supply can provide power to components such as the heater, induction coil, and control unit.

[0035] The control unit can control the overall operation of the aerosol generator 1. The control unit may be mounted on a printed circuit board (PCB). The control unit can control the operation of components such as heaters, induction coils, and power supplies. The control unit can control the operation of displays, actuators (motors), and other components installed in the aerosol generator 1. The control unit can check the status of each component of the aerosol generator 1 and determine whether the aerosol generator 1 is operating or not.

[0036] Figure 2 is a diagram illustrating an aerosol generating apparatus according to one embodiment, Figure 3 is a diagram illustrating an aerosol generating apparatus according to another embodiment, and Figure 4 is a diagram illustrating an aerosol generating apparatus according to yet another embodiment.

[0037] Referring to Figure 2, the aerosol generating device 1 according to an embodiment of the present invention may include at least one of the following: a battery 12, a control unit 13, a sensor unit 14, and a heater 15. At least one of the following: the battery 12, the control unit 13, the sensor unit 14, and the heater 15 may be located inside the main body 10 of the aerosol generating device 1.

[0038] The main body 10 can provide a space that opens on one side into which an aerosol product 2 can be inserted. The space that opens on one side is referred to as the article storage section. The article storage section may be formed by recessing into the main body 10 to a predetermined depth so that at least a portion of the aerosol product 2 can be inserted. The depth of the article storage section may correspond to the length of the region in the aerosol product 2 that contains the aerosol-generating substance and / or medium. The lower end of the aerosol product 2 is inserted into the main body 10, and a portion of the aerosol product 2 may protrude outside the main body 10. The user can inhale air by putting the portion of the aerosol product 2 that is exposed to the outside into their mouth.

[0039] The heater 15 can heat the aerosol product 2. The heater 15 may extend outward in the longitudinal direction of the space into which the aerosol product 2 is inserted. For example, the heater 15 may include a tubular heating element, a plate heating element, a needle heating element, or a rod heating element. The heater 15 may be inserted into one end of the aerosol product 2. The heater 15 may include an electrical resistance heater and / or an induction heating heater.

[0040] For example, referring to Figure 2, heater 15 is also a resistive heater. For example, heater 15 may include a conductive track, and heater 15 may be heated by current flowing through the conductive track. Heater 15 may be electrically connected to battery 12. Heater 15 may be directly heated by current supplied from battery 12.

[0041] For example, heater 15 is also a multiple heater. Heater 15 may include a first heater 15A and a second heater 15B. The first and second heaters 15A and 15B may be arranged side by side along the longitudinal direction. The first and second heaters 15A and 15B may be heated sequentially or simultaneously.

[0042] For example, referring to Figure 3, the aerosol generator includes an induction coil 151 surrounding a heater 15. The induction coil 151 can cause the heater 15 to heat up. The heater 15 is a susceptor, and the heater 15 can be heated by a magnetic field generated by an AC current flowing through the induction coil 151. The magnetic field penetrates the heater 15, generating eddy currents within the heater 15. The current generates heat in the heater 15.

[0043] For example, referring to Figure 4, a susceptor 152 is included inside the aerosol product 2, and the susceptor 152 inside the aerosol product 2 may be heated by the magnetic field generated by the AC current flowing through the induction coil 151. The susceptor 152 is located inside the aerosol product 2 and does not need to be electrically connected to the aerosol generator 1. The susceptor 152 can be inserted into the article storage section together with the aerosol product 2 and can be removed from the article storage section together with the aerosol product 2. The aerosol product 2 may be heated by the susceptor 152 inside the aerosol product 2. In this case, the aerosol generator does not need to be equipped with a heater 15.

[0044] The battery 12 can supply power to the components of the aerosol generator. The battery 12 can supply power to at least one of the control unit 13, the sensor unit 14, and the heater 15. The battery 12 can supply power to the induction coil 151.

[0045] The battery 12 is a detachable power source for the aerosol generator 1. For example, the battery 12 is detachably connected to a battery housing space (not shown) of the aerosol generator 1, electrically connected to terminals in the battery housing space, and can supply power to the components of the aerosol generator 1.

[0046] The aerosol generator 1 may further include a charging interface for connecting the aerosol generator 1 to an external power source. For example, the battery 12 may be electrically connected to an external power source (e.g., a charger) through the charging interface, and the battery 12 may be charged by power supplied from the external power source.

[0047] The control unit 13 can control the overall operation of the aerosol generator 1. The control unit may be mounted on a printed circuit board (PCB). The control unit 13 can control the operation of at least one of the following: the battery 12, the sensor unit 14, and the heater 15. The control unit 13 can control the operation of the induction coil 151. The control unit 13 can control the operation of the display, actuator (motor), etc., installed in the aerosol generator 1. The control unit 13 can check the status of each component of the aerosol generator 1 and determine whether the aerosol generator 1 is operational or not.

[0048] The control unit 13 can analyze the results sensed by the sensor unit 14 and control subsequent processing. For example, based on the results sensed by the sensor unit 14, the control unit 13 can control the power supplied to the heater 15 so that the operation of the heater 15 is started or stopped. For example, based on the results sensed by the sensor unit 14, the control unit 13 can control the amount of power supplied to the heater 15 and the power supply time so that the heater 15 is heated to a predetermined temperature or maintained at an appropriate temperature.

[0049] The sensor unit 14 may include at least one of a temperature sensor, a puff sensor, an insertion sensor, or an acceleration sensor. For example, the sensor unit 14 can sense at least one of the following: the temperature of the heater 15, the temperature of the battery 12, or the temperature inside or outside the main unit 10. For example, the sensor unit 14 can sense the user's puff. For example, the sensor unit 14 can sense whether or not an aerosol product 2 has been inserted into the article storage compartment. For example, the sensor unit 14 can sense the movement of the aerosol generator.

[0050] Figure 5 is a diagram illustrating an aerosol generating apparatus according to yet another embodiment, and Figure 6 is a diagram illustrating an aerosol generating apparatus according to yet another embodiment.

[0051] Referring to Figure 5, the aerosol generator 1 may include a cartridge 3 and a main body 10. The aerosol generator 1 may include at least one of a battery 12, a control unit 13, and a sensor (not shown). At least one of the control unit 13 and the battery 12 may be located inside the main body 10. The main body 10 may be fitted with a cartridge 3 containing an aerosol generating substance. The user can inhale the aerosol by putting a mouthpiece (not shown) provided at one end of the cartridge 3 into their mouth.

[0052] Cartridge 3 may contain an aerosol-generating substance in its internal storage space 31, which may be in one of the following states: liquid, solid, gas, or gel. The aerosol-generating substance may include a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance that includes volatile tobacco flavor components, or a liquid containing a non-tobacco substance.

[0053] Cartridge 3 can be detachably attached to the main unit 10. By being attached to the main unit 10, cartridge 3 can be mounted on the main unit 10.

[0054] The main unit 10 has a structure that allows outside air to flow into the main unit 10 while the cartridge 3 is attached. At this time, the outside air that flows into the main unit 10 can pass through the cartridge 3 and flow into the user's mouth through the airflow channel CN.

[0055] Cartridge 3 may include a storage space 31 and / or a generating section 32 containing aerosol-generating material. The generating section 32 can heat the aerosol-generating material in the storage space 31. Cartridge 3 may include a liquid transfer means 33 that absorbs the aerosol-generating material. Here, the liquid transfer means 33 may include a wick such as cotton fibers, ceramic fibers, glass fibers, or porous ceramic. The conductive track of the generating section 32 consists of a coil-like structure that winds the liquid transfer means 33 or a structure that contacts one side of the liquid transfer means 33. The generating section 32 is referred to as the "cartridge heater".

[0056] Cartridge 3 can generate an aerosol. As the liquid transmission means 33 is heated by the generation unit 32, an aerosol can be generated. The generated aerosol can be inhaled into the user's mouth through the airflow channel CN.

[0057] The airflow channel CN ​​is provided in the cartridge 3. The airflow channel CN ​​can connect the generating section 32 of the cartridge 3 to the outside of the cartridge. One end of the airflow channel CN ​​may open to the generating section 32, and the other end may be connected to the outside. For example, the airflow channel CN ​​may extend along the longitudinal direction of the cartridge 3 from one side of the storage space 31 of the cartridge 3. For example, the airflow channel CN ​​may extend through the cartridge 3 along the longitudinal direction of the cartridge 3.

[0058] Referring to Figure 6, in one embodiment, the aerosol generating apparatus 1 can contain the aerosol product 2. For example, the aerosol product 2 can be contained in a cartridge 3. As another example, the aerosol product 2 can be contained in the main body 10.

[0059] The aerosol product 2 can pass through the aerosol generated from the generation unit 32. The aerosol generator 1 includes an article storage unit that contains the aerosol product 2, and the aerosol generated from inside the generation unit 32 can pass through the aerosol product 2 stored in the article storage unit and be discharged to the outside of the aerosol generator 1. At this time, the user can bring their mouth into contact with the aerosol product 2 and inhale the aerosol discharged to the outside of the aerosol generator 1 through the aerosol product 2.

[0060] Referring to Figure 6, the aerosol generator 1 may further include a heater 15 for heating the aerosol product 2. The heater 15 can heat the aerosol product 2. The heater 15 may be positioned around the space into which the aerosol product 2 is inserted. The heater 15 may include an electrical resistance heater and / or an induction heater.

[0061] The control unit 13 can control the overall operation of the aerosol generator 1. The control unit 13 may be located on a printed circuit board (PCB). The control unit 13 can control the operation of at least one of the cartridge 3, battery 12, and sensor. For example, the control unit 13 can control the operation of a display (not shown), an acoustic output device (not shown), a haptic unit (not shown), an actuator (motor) (not shown), etc., installed in the aerosol generator 1. The control unit 13 can check the status of each component of the aerosol generator 1 and determine whether the aerosol generator 1 is operational or not.

[0062] The control unit 13 can analyze the results sensed by the sensor and control subsequent processing. For example, based on the results sensed by the sensor, the control unit 13 can control the power supplied to the generation unit 32 so that the operation of the generation unit 32 is started or stopped. For example, based on the results sensed by the sensor, the control unit 13 can control the amount of power supplied to the generation unit 32 and the power supply time so that the generation unit 32 is heated to a predetermined temperature or maintained at an appropriate temperature.

[0063] The battery 12 can supply power to the components of the aerosol generator 1. For example, the battery 12 can provide electrical energy to at least one of the control unit 13, a sensor (not shown), and a heater 15.

[0064] The sensor may include at least one of the following: a temperature sensor, a puff sensor, a cartridge sensing sensor, and a motion sensing sensor. For example, the sensor can sense at least one of the following: the temperature of the generation unit 32, the temperature of the battery 12, and the temperature inside and outside the main unit 10. For example, the sensor can sense the user's puff. For example, the sensor can sense whether a cartridge is installed or not. For example, the sensor can sense the movement of the aerosol generator 1.

[0065] Figure 7 is an exploded perspective view of a partial configuration of an aerosol generator according to one embodiment. Although only the housing 110, battery 120, and battery cover 112 of the aerosol generator 100 are shown in Figure 7, the components of the aerosol generator 100 are not limited to the configuration shown in the drawing.

[0066] Referring to Figure 7, one embodiment of the aerosol generator 100 may include a housing 110, a battery cover 112, a battery 120, and a battery protection circuit 140. The aerosol generator 100 is one embodiment of the aerosol generator 1 shown in Figures 1 to 6, and redundant explanations will be omitted below.

[0067] The housing 110 forms the overall appearance of the aerosol generator 100, and components of the aerosol generator 100 may be arranged in the housing 110. For example, the housing 110 may house, but is not limited to, a heater (e.g., heater 15 in Figures 2, 3, and 5) or a generation unit (e.g., generation unit 32 in Figure 5) for heating the aerosol-generating material to produce an aerosol, and a processor (e.g., control unit 13 in Figures 2 to 6).

[0068] According to one embodiment, the housing 110 may include a battery housing space 110h for housing a battery 120. For example, the battery housing space 110h is formed in a region of the housing 110 (for example, a region facing the x-direction) to house the battery 120, but the location of the battery housing space 110h is not limited thereto.

[0069] At least one terminal 111 is provided in the battery housing space 110h, and at least one terminal 111 can contact the electrodes 121 of the battery 120 when the battery 120 is coupled to or housed in the battery housing space 110h. Although only an embodiment in which two terminals 111 are provided on the side of the battery housing space 110h is shown in the drawings, the arrangement structure or number of at least one terminal 111 is not limited thereto.

[0070] The battery 120 is detachably coupled to the battery housing space 110h of the housing 110 and can supply power for the operation of the components of the aerosol generator 100. For example, when the battery 120 is coupled to the battery housing space 110h, the electrodes 121 of the battery 120 come into contact with at least one terminal 111, thereby electrically coupling the battery 120 with the components of the aerosol generator 100 (e.g., a heater processor). The battery 120 can supply power to the electrically coupled components of the aerosol generator 100 and operate the components of the aerosol generator 100.

[0071] According to one embodiment, the aerosol generator 100 may further include a battery cover 112 for securing a battery 120 in a battery housing space 110h. The battery cover 112 is detachably coupled to the housing 110 and can open or close the battery housing space 110h. For example, when the battery cover 112 is detached from the housing 110, the battery housing space 110h is exposed to the outside of the aerosol generator 100, and the battery 120 can be coupled to the battery housing space 110h. As another example, when the battery cover 112 is coupled to the housing 110, the battery housing space 110h does not need to be covered by the battery cover 112 and exposed to the outside, and the battery 120h housed in the battery housing space 110h can be secured inside the battery housing space 110h by the battery cover 112.

[0072] In another embodiment, the aerosol generator 100 may further include a fixing member (not shown) for fixing a removable battery 120 to the battery housing space 110h, which is located in the battery housing space 110h. In this case, the aerosol generator 100 may fix the battery 120 to the battery housing space 110h without a battery cover 112, and the battery 120 may form the appearance of the aerosol generator 100 together with the housing 110.

[0073] The battery protection circuit 140 (or "Protection Circuit Module (PCM)") can be electrically connected to the battery 120 when the battery 120 is coupled to the battery housing space 110h, thereby protecting and / or managing the battery 120. For example, the battery protection circuit 140 may be arranged to be electrically connected to at least one terminal 111. This allows the battery protection circuit 140 to be electrically connected to the battery 120 in contact with at least one terminal 111 when the battery 120 is coupled to the battery housing space 110h.

[0074] For example, the battery protection circuit 140 can prevent overcharging of the battery 120 during charging, thereby preventing the battery 120 from exploding due to overcharging. As another example, the battery protection circuit 140 can prevent over-discharge of the battery 120 or overcurrent flowing through the battery 120, thereby preventing malfunction or damage to the battery 120.

[0075] According to one embodiment, the battery protection circuit 140 may be placed on a printed circuit board 130 located in a region of the housing 110 adjacent to the battery housing space 110h. The printed circuit board 130 is located in a region of the housing 110 that is separated from a heater (not shown), thereby allowing the battery protection circuit 140 to be placed at a predetermined distance from the heater. In the present invention, "predetermined distance" means the minimum distance at which the battery protection circuit 140 is not affected by the heat generated by the heater. The aerosol generator 100 according to one embodiment can prevent malfunction or damage to the battery protection circuit 140 by the heater through a structure in which the battery protection circuit 140 is separated from the heater at a predetermined distance.

[0076] In one embodiment, the aerosol generator 100 allows the battery protection circuit 140 to be used continuously even when the battery 120 is replaced, through a structure in which the battery 120 and the battery protection circuit 140 are physically separated.

[0077] Existing aerosol generators typically use a battery pack that integrates a battery 120 and a battery protection circuit 140. However, when using a battery pack, even if the battery protection circuit 140 is functioning correctly, once the battery 120 reaches the end of its lifespan, the battery pack must be replaced with a new one, resulting in high costs when replacing the battery pack.

[0078] On the other hand, in one embodiment of the aerosol generator 100, the battery 120 and the battery protection circuit 140 are separated, allowing for the recycling of the battery protection circuit 140 when the battery 120 is replaced or discarded, thereby reducing the cost of replacing the battery 120.

[0079] Furthermore, a battery protection circuit 140 is necessary for the stable use of the battery 120. In one embodiment, the aerosol generator 100 has a structure in which the battery 120 and the battery protection circuit 140 are separated, so that one battery protection circuit 140 protects various types of batteries, and as a result, various types of batteries other than the battery specified by the user can be used.

[0080] In the following section, with reference to Figure 8, we will specifically describe the structure in which the battery 120 and the components of the aerosol generator 100 are electrically connected when the battery 120 is coupled to the battery housing space 110h.

[0081] Figure 8 is a diagram illustrating the electrical connections between the battery, battery protection circuit, and processor of the aerosol generator shown in Figure 7.

[0082] Referring to Figure 8, one embodiment of the aerosol generator 100 may include a housing 110 including a battery housing space 110h, a battery 120, a printed circuit board 130, a battery protection circuit 140, and a processor 150. The components of the aerosol generator 100 are substantially identical or similar to at least one of the components of the aerosol generator 100 in Figure 7, and redundant explanations will be omitted below.

[0083] The battery 120 is detachably connected to the battery housing space 110h, and when connected to the battery housing space 110h, it can be electrically connected to the battery protection circuit 140 and the processor 150.

[0084] According to one embodiment, the battery housing space 110h may have at least one terminal 111 that is electrically connected to the battery protection circuit 140 and / or the processor 150. For example, the at least one terminal 111 includes an electrode located on one side of the battery housing space 110h, but the type or arrangement of the at least one terminal 111 is not limited thereto.

[0085] When the battery 120 is coupled to or housed in the battery housing space 110h, the electrodes 121 of the battery 120 come into contact with at least one terminal 111 of the battery housing space 110h, and this contact between the battery 120 and at least one terminal 111 can electrically connect the battery 120 and at least one terminal 111 to each other. Consequently, the battery protection circuit 140 and / or the processor 150 can be electrically connected to the battery 120 through at least one terminal 111 by the electrical connection between at least one terminal 111 and the battery 120.

[0086] The battery protection circuit 140 is electrically connected to the battery 120 and can protect and / or manage the battery 120. For example, if the voltage of the battery 120 rises above a specified first voltage during charging, the battery protection circuit 140 can cut off the power supplied to the battery 120 to prevent overcharging. As another example, if the voltage of the battery 120 drops below a specified second voltage, the battery protection circuit 140 can cut off the power supply to the battery 120 to prevent over-discharge.

[0087] The processor 150 (for example, the control unit 13 in Figures 2 to 6) can control the overall operation of the aerosol generator 100. For example, the processor 150 can control the power supplied from the battery 120 to the components of the aerosol generator 100 (e.g., the heater) to generate aerosols from the aerosol-generating material. As another example, the processor 150 can control the operation of the battery protection circuit 140 to protect the battery 120 from overcharging, over-discharging, or overcurrent inflow.

[0088] According to one embodiment, the processor 150 can detect the type of battery 120 coupled to the battery housing space 110h based on the characteristics of the battery 120, and can control the charging or discharging of the battery 120 based on the detected type of battery 120. In one embodiment, the aerosol generator 100 uses various types of batteries 120 through a structure in which the battery 120 and the battery protection circuit 140 are separated, so that the processor 150 can detect the type of battery 120 and control the charging and / or discharging of the battery 120 according to the type of battery 120 for stable operation of the battery 120.

[0089] The following describes the operation of detecting the type of battery 120 in an aerosol generator 100 according to one embodiment and controlling the charging or discharging of the battery 120, with reference to Figures 9 and 10.

[0090] Figure 9 is a flowchart illustrating the operation of detecting the type of battery in an aerosol generator according to one embodiment and controlling the charging or discharging of the battery. Figure 10 is a graph showing the voltage change of batteries over time when various types of batteries are discharged. In Figure 10, curve 1001 shows the voltage change during discharge of the first battery, curve 1002 shows the voltage change during discharge of the second battery, and curve 1003 shows the voltage change during discharge of the third battery.

[0091] In the following explanation of the operation shown in Figure 9, we will refer to the components of the aerosol generator 100 shown in Figure 8.

[0092] Referring to Figures 9 and 10, in operation 901, the processor 150 of the aerosol generator 100 can detect the type of battery 120 coupled to or housed in the battery housing space 110h based on the charging or discharging characteristics of the battery 120.

[0093] Depending on the type of battery 120 coupled to the battery housing space 110h, the charging and discharging characteristics of the batteries 120 will differ from those of the batteries 120 coupled to the battery housing space 110h. As a result, the processor 150 of the aerosol generator 100 can detect the type of battery 120 coupled to the battery housing space 110h by comparing the charging or discharging characteristics of the batteries 120 with characteristics stored in advance.

[0094] For example, the discharge rates of the batteries 120 differ depending on the type of battery 120 coupled to the battery housing space 110h. In this invention, "discharge rate" means the rate of change in the voltage of the battery 120 during a specified time interval when the battery 120 is discharged.

[0095] For example, as shown in Figure 10, the discharge rate of the second battery is lower than that of the first battery, and the discharge rate of the third battery is higher than that of the first battery. As a result, the processor 150 can calculate the discharge rate of battery 120 and detect the type of battery 120 by comparing the calculated discharge rate of battery 120 with pre-stored data on battery discharge rates.

[0096] As another example, although not shown in the drawings, when the battery 120 is charged by an external power source, the charge rate of the battery 120 will differ depending on the type of battery 120. In this invention, "charge rate" means the rate of change of the voltage of the battery 120 during a specified time interval when the battery 120 is charged by an external power source.

[0097] For example, the charge level of the second battery is lower than that of the first battery, and the charge level of the third battery is higher than that of the first battery. As a result, when the processor 150 detects the connection between the external power supply and the battery 120, it can calculate the charge level of the battery 120 and compare the calculated charge level of the battery 120 with pre-stored data on battery charge levels to detect the type of battery 120.

[0098] In this context, data relating to the battery's charge or discharge rate means, but is not limited to, data pre-stored in the processor 150 or memory (not shown).

[0099] In operation 902, the processor 150 of the aerosol generator 100 can control the charging or discharging of the battery 120 based on the type of battery 120 detected in operation 901. For example, the processor 150 can determine whether the battery 120 is overcharged or over-discharged based on the detected type of battery 120, and prevent overcharging or over-discharging of the battery 120 through the battery protection circuit 140.

[0100] For example, if the processor 150 determines that a first battery has been connected to the battery housing space 110h, it can charge or discharge the first battery according to the characteristics of the first battery. As another example, if the processor 150 determines that a second battery different from the first battery has been connected to the battery housing space 110h, it can charge or discharge the second battery according to the characteristics of the second battery.

[0101] In the following, with reference to Figures 11 to 12, the type of battery 120 of the processor 150 is detected, and the control operation of the battery 120 is specifically described based on the detected type of battery 120.

[0102] Figure 11 is a flowchart illustrating the operation of controlling the charging or discharging of a battery based on the battery discharge rate of an aerosol generator according to one embodiment. In the following description of the operation in Figure 11, the components of the aerosol generator 100 in Figure 8 will be referred to.

[0103] Referring to Figure 11, in operation 1101, the processor 150 of the aerosol generator 100 according to one embodiment can calculate the discharge rate of the battery 120 coupled to the battery housing space 110h. For example, when the battery 120 is discharged, the processor 150 can calculate the discharge rate of the battery 120 based on the amount of voltage change of the battery 120 during a specified time interval.

[0104] In operation 1102, the processor 150 can detect the type of battery 120 coupled to the battery housing space 110h by comparing the discharge rate of battery 120 calculated in operation 1101 with pre-stored data on battery discharge rates. For example, the processor 150 can detect what type of battery 120 is by comparing the calculated discharge rate of battery 120 with data on battery discharge rates stored in the processor 150 or memory (not shown).

[0105] In operation 1103, the processor 150 can determine whether the detected battery 120 is the first battery. For example, the processor 150 can compare the discharge rate of battery 120 calculated in operation 1101 with data on the discharge rate of the first battery that has been stored in advance, and determine whether the battery 120 coupled to the battery housing space 110h is the first battery.

[0106] If operation 1103 determines that battery 120 is the first battery, then operation 1104 allows the processor 150 to control the charging or discharging of the first battery through the battery protection circuit 140 based on the characteristics of the first battery.

[0107] For example, if the voltage of the first battery is above a specified first reference value when the first battery is being charged, the processor 150 can determine that the first battery is overcharged and cut off the power supplied to the first battery from an external power source via the battery protection circuit 140. In the present invention, the "specified first reference value" means the upper limit of the voltage of the first battery which serves as a criterion for determining whether or not the first battery is overcharged.

[0108] As another example, if the voltage of the first battery is below a specified second reference value during discharge of the first battery, the processor 150 may determine that the first battery is in an over-discharged state and interrupt the discharge of the first battery through the battery protection circuit 140, thereby cutting off the supply of power from the first battery to other components of the aerosol generator 100. In the present invention, the "specified second reference value" means the lower limit of the voltage of the first battery which serves as a criterion for determining whether or not the first battery is over-discharged.

[0109] On the other hand, if operation 1103 determines that battery 120 is not the first battery, then in operation 1105, the processor 150 can determine whether the detected battery 120 is the second battery. For example, the processor 150 can compare the discharge rate of battery 120 calculated in operation 1101 with pre-stored data on the discharge rate of the second battery to determine whether the battery 120 coupled to the battery housing space 110h is the second battery.

[0110] If operation 1105 determines that battery 120 is the second battery, then operation 1106 allows the processor 150 to control the charging or discharging of the second battery through the battery protection circuit 140 based on the characteristics of the second battery.

[0111] For example, if the voltage of the second battery is above a specified third reference value during charging of the second battery, the processor 150 can determine that the second battery is overcharged and cut off the power supplied to the second battery from an external power source via the battery protection circuit 140. In this invention, the "specified third reference value" means the upper limit of the voltage of the second battery which serves as a criterion for determining whether the second battery is overcharged, and is a different value from the first reference value.

[0112] As another example, if the voltage of the second battery is below a specified fourth reference value during discharge of the second battery, the processor 150 may determine that the second battery is over-discharged and interrupt the discharge of the second battery through the battery protection circuit 140, thereby cutting off the supply of power from the second battery to other components of the aerosol generator 100. In this invention, the "specified fourth reference value" means the lower limit of the voltage of the second battery which serves as a criterion for determining whether or not the second battery is over-discharged, and is a different value from the second reference value.

[0113] If operation 1105 determines that battery 120 is not the second battery, the processor 150 may repeat operations 1101 to 1103, or detect whether battery 120 is of another type (e.g., a third battery), and control charging or discharging of battery 120 through the battery protection circuit 140 based on the type of battery 120.

[0114] An aerosol generator 100 according to one embodiment can improve user convenience by protecting and / or managing various types of batteries 120 through a single battery protection circuit 140 via the aforementioned 1101 to 1106 operations.

[0115] Figure 12 is a flowchart illustrating the operation of controlling the charging or discharging of a battery based on the battery charge level of an aerosol generator according to another embodiment.

[0116] In the following description of the operation shown in Figure 12, we will refer to the components of the aerosol generator 100 shown in Figure 8.

[0117] Referring to Figure 12, in operation 1201, the processor 150 of the aerosol generator 100 according to another embodiment can calculate the charge level of the battery 120 coupled to the battery housing space 110h when the battery 120 is charged from an external power source. For example, when the connection between the aerosol generator 100 and an external power source is detected, the processor 150 can calculate the charge level of the battery 120 based on the change in the voltage of the battery 120 during a specified time interval from the time the external power source was connected.

[0118] In operation 1202, the processor 150 can detect the type of battery 120 coupled to the battery housing space 110h by comparing the battery charge rate calculated in operation 1201 with pre-stored data on battery charge rates. For example, the processor 150 can detect what type of battery 120 is by comparing the calculated battery charge rate with data on battery charge rates stored in the processor 150 or memory (not shown).

[0119] In operation 1203, the processor 150 can determine whether the detected battery 120 is the first battery. For example, the processor 150 can compare the charge rate of battery 120 calculated in operation 1201 with data on the charge rate of the first battery that has been stored in advance, and determine whether the battery 120 coupled to the battery housing space 110h is the first battery.

[0120] In operation 1203, if it is determined that battery 120 is the first battery, in operation 1204, the processor 150 can control the charging or discharging of the first battery through the battery protection circuit 140 based on the characteristics of the first battery. Operation 1204 is substantially identical or similar to operation 1104 in Figure 11, and redundant explanations are omitted below.

[0121] On the other hand, if operation 1203 determines that battery 120 is not the first battery, then in operation 1205, the processor 150 can determine whether the detected battery 120 is the second battery. For example, the processor 150 can compare the charge rate of battery 120 calculated in operation 1201 with pre-stored data on the charge rate of the second battery to determine whether the battery 120 coupled to the battery housing space 110h is the second battery.

[0122] If operation 1205 determines that battery 120 is the second battery, then operation 1206 allows the processor 150 to control the charging or discharging of the second battery through the battery protection circuit 140 based on the characteristics of the second battery. Operation 1206 is substantially identical or similar to operation 1106 in Figure 11, and redundant explanations are omitted below.

[0123] If operation 1205 determines that battery 120 is not the second battery, the processor 150 may repeat operations 1201 to 1203, or detect whether battery 120 is of another type (e.g., a third battery), and control the charging or discharging of battery 120 through the battery protection circuit 140 based on the type of battery 120.

[0124] In other embodiments, the aerosol generator 100 protects and / or manages various types of batteries 120 through a single battery protection circuit 140 via the aforementioned 1001 to 1106 operations, thereby improving user convenience.

[0125] Figure 13 is a block diagram of an aerosol generating apparatus according to one embodiment.

[0126] The aerosol generator 1 includes a battery 12, a control unit 13, a sensor unit 14, an output unit 40, an input unit 70, a communication unit 50, a memory 60, and at least one heater 15. However, the internal structure of the aerosol generator 1 is not limited to that shown in Figure 13. That is, a person with ordinary skill in the art according to this embodiment will understand that some of the components shown in Figure 13 may be omitted or new components may be added depending on the design of the aerosol generator 1.

[0127] The sensor unit 14 can sense the state of the aerosol generator 1 or the state of the area around the aerosol generator 1 and transmit the sensed information to the control unit 13. Based on the sensed information, the control unit 13 can control the aerosol generator 1 to perform various functions such as controlling the operation of the cartridge heater 15 and / or stick heater 15, restricting smoking, determining whether or not a stick and / or cartridge 19 is inserted, and displaying notifications.

[0128] The sensor unit 14 includes at least one of the following: a temperature sensor 141, a puff sensor 142, an insertion sensor 143, a reuse sensor 144, a cartridge sensor 145, a cap sensor 146, and a motion sensor 147.

[0129] The temperature sensor 141 can sense the temperature at which the cartridge heater 15 and / or stick heater 15 are heated. The aerosol generator 1 may include a separate temperature sensor that senses the temperature of the cartridge heater 15 and / or stick heater 15, or the cartridge heater 15 and / or stick heater 15 themselves may act as the temperature sensor.

[0130] The temperature sensor 141 can output a signal corresponding to the temperature of the cartridge heater 15 and / or the stick heater 15. For example, the temperature sensor 141 includes a resistive element whose resistance changes in response to temperature changes in the cartridge heater 15 and / or the stick heater 15. This is embodied by an element such as a thermistor, which utilizes the property that resistance changes with temperature. In this case, the temperature sensor 141 can output a signal corresponding to the resistance value of the resistive element as a signal corresponding to the temperature of the cartridge heater 15 and / or the stick heater 15. For example, the temperature sensor 141 is composed of a sensor that detects the resistance value of the cartridge heater 15 and / or the stick heater 15. In this case, the temperature sensor 141 can output a signal corresponding to the resistance value of the cartridge heater 15 and / or the stick heater 15 as a signal corresponding to the temperature of the cartridge heater 15 and / or the stick heater 15.

[0131] The temperature sensor 141 may be positioned around the battery 12 to monitor its temperature. The temperature sensor 141 may be positioned adjacent to the battery 12. For example, the temperature sensor 141 may be attached to one side of the battery 12. For example, the temperature sensor 141 may be mounted on one side of a printed circuit board.

[0132] The temperature sensor 141 is located inside the main unit 10 and can sense the internal temperature of the main unit 10.

[0133] The puff sensor 142 can detect user puffs based on various physical changes in the airflow path. The puff sensor 142 can output a signal corresponding to a puff. For example, the puff sensor 142 is also a pressure sensor. The puff sensor 142 can output a signal corresponding to the internal pressure of the aerosol generator 1. Here, the internal pressure of the aerosol generator 1 corresponds to the pressure of the airflow path through which the gas flows. The puff sensor 142 can be positioned in the aerosol generator 1 corresponding to the airflow path through which the gas flows.

[0134] The insertion sensor 143 can detect the insertion and / or removal of the stick. The insertion sensor 143 can detect the signal change caused by the insertion and / or removal of the stick. The insertion sensor 143 can be installed around the insertion space. The insertion sensor 143 can detect the insertion and / or removal of the stick by the change in dielectric constant inside the insertion space. For example, the insertion sensor 143 is also an inductive sensor and / or a capacitance sensor.

[0135] An inductive sensor includes at least one coil. The coil of the inductive sensor is positioned adjacent to the insertion space. For example, if the magnetic field changes around a coil through which current flows, the characteristics of the current flowing through the coil may change according to Faraday's law of electromagnetic induction. Here, the characteristics of the current flowing through the coil include the frequency of the alternating current, the current value, the voltage value, the inductance value, the impedance value, etc.

[0136] An inductive sensor can output a signal that corresponds to the characteristics of the current flowing through a coil. For example, an inductive sensor can output a signal that corresponds to the inductance value of a coil.

[0137] A capacitance sensor includes a conductor. The conductor of the capacitance sensor is positioned adjacent to the insertion space. The capacitance sensor can output a signal corresponding to the surrounding electromagnetic properties, such as the capacitance around the conductor. For example, if a stick including a metal ferrule is inserted into the insertion space, the ferrule of the stick can alter the electromagnetic properties around the conductor.

[0138] The reuse detection sensor 144 can detect whether the stick has been reused. The reuse detection sensor 144 is also a color sensor. The color sensor can detect the hue of the stick. The color sensor can detect the hue of a portion of the trumpet surrounding the outside of the stick. The color sensor can detect values ​​related to the optical properties corresponding to the hue of an object, based on the light reflected from the object. For example, the optical properties are also the wavelength of light. The color sensor may be implemented as a single configuration with the proximity sensor, or as a separate configuration distinct from the proximity sensor.

[0139] At least a portion of the flaps that make up the stick may change hue due to aerosols. The reuse sensing sensor 144 may be positioned in a location corresponding to where at least a portion of the flaps whose hue changes due to aerosols are located when the stick is inserted into the insertion space. For example, before the stick is used by a user, at least a portion of the flaps has a first hue. In this case, as the aerosol generated by the aerosol generator 1 passes through the stick, at least a portion of the flaps may be wetted by the aerosol, causing at least a portion of the flaps to change to a second hue. On the other hand, at least a portion of the flaps may remain at the second hue after being changed from the first hue to the second hue.

[0140] The cartridge sensing sensor 145 can detect the insertion and / or removal of the cartridge 19. The cartridge sensing sensor 145 can be implemented as an inductance substrate sensor, a capacitive sensor, a resistive sensor, or a Hall sensor (Hall IC) using the Hall effect.

[0141] The cap sensing sensor 146 can detect the attachment and / or removal of the cap. When the cap is separated from the main body 10, a portion of the cartridge 19 and the main body 10 that was covered by the cap may be exposed to the outside. The cap sensing sensor 146 can be implemented by a contact sensor, a Hall sensor (Hall IC), an optical sensor, or the like.

[0142] The motion sensing sensor 147 can detect the movement of the aerosol generator. The motion sensing sensor 147 is embodied by at least one of an acceleration sensor and a gyro sensor.

[0143] In addition to the aforementioned sensors 141 to 147, the sensor unit 14 may further include at least one of the following: a humidity sensor, a pressure sensor, a magnetic sensor, a position sensor (GPS), and a proximity sensor. The function of each sensor can be intuitively inferred by an average engineer from its name, so a detailed explanation is omitted.

[0144] The output unit 40 can output and provide to the user information about the status of the aerosol generator 1. The output unit 40 includes, but is not limited to, a display unit 41, a haptic unit 42, and an acoustic output unit 43. When the display unit 41 and the touchpad form a layered structure and constitute a touchscreen, the display unit 41 can be used as an input device in addition to an output device.

[0145] The display unit 41 can visually provide the user with information about the aerosol generator 1. For example, the information about the aerosol generator 1 can include various types of information such as the charge / discharge status of the battery 12 of the aerosol generator 1, the preheating status of the stick heater 15, the insertion / removal status of the stick and / or cartridge 19, the attachment / removal status of the cap, or a state in which the use of the aerosol generator 1 is restricted (e.g., detection of an abnormal object), and the display unit 41 can output this information to the outside. For example, the display unit 41 can also be in the form of an LED light-emitting element. For example, the display unit 41 can be a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), etc.

[0146] The haptic unit 42 can convert electrical signals into mechanical or electrical stimuli, providing the user with tactile information about the aerosol generator 1. For example, the haptic unit 42 generates vibrations corresponding to the completion of initial preheating when initial power is supplied to the cartridge heater 15 and / or stick heater 15 for a set time. The haptic unit 42 may include a vibration motor, a piezoelectric element, or an electrical stimulator.

[0147] The acoustic output unit 43 can provide the user with auditory information about the aerosol generator 1. For example, the acoustic output unit 43 can convert electrical signals into acoustic signals and output them externally.

[0148] The battery 12 can supply power used to operate the aerosol generator 1. The battery 12 can supply power to heat the cartridge heater 15 and / or the stick heater 15. The battery 12 can also supply power necessary for the operation of other components provided in the aerosol generator 1, namely the sensor unit 14, the output unit 40, the input unit 70, the communication unit 50, and the memory 60. The battery 12 may be a rechargeable battery or a disposable battery. For example, the battery 12 is a lithium polymer (LiPoly) battery, but is not limited to that.

[0149] Although not shown in Figure 13, the aerosol generator 1 may further include a power protection circuit. The power protection circuit is electrically connected to the battery 12 and may include a switching element.

[0150] The power protection circuit can shut off the circuit to the battery 12 under predetermined conditions. For example, the power protection circuit can shut off the circuit to the battery 12 if the voltage level of the battery 12 is equal to or greater than a first voltage corresponding to overcharging. For example, the power protection circuit can shut off the circuit to the battery 12 if the voltage level of the battery 12 is less than a second voltage corresponding to over-discharge.

[0151] The stick heater 15 is powered by the battery 12 and can heat the medium or aerosol-generating material inside the stick. Although not shown in Figure 13, the aerosol generator 1 may further include a power conversion circuit (e.g., a DC / DC converter) that converts the power from the battery 12 and supplies it to the cartridge heater 15 and / or the stick heater 15. Also, if the aerosol generator 1 generates aerosols by induction heating, the aerosol generator 1 may further include a DC / AC converter that converts the DC power from the battery 12 to AC power.

[0152] The control unit 13, sensor unit 14, output unit 40, input unit 70, communication unit 50, and memory 60 can function by being powered by the battery 12. Although not shown in Figure 13, a power conversion circuit, such as an LDO (low dropout) circuit or a voltage regulator circuit, may be further included to convert the power from the battery 12 and supply it to each component. Also, although not shown in Figure 13, a noise filter may be provided between the battery 12 and the stick heater 15. The noise filter is also a low-pass filter. The low-pass filter may include at least one inductor and a capacitor. The cutoff frequency of the low-pass filter corresponds to the frequency of the high-frequency switching current applied from the battery 12 to the stick heater 15. The low-pass filter prevents high-frequency noise components from being applied to the sensor unit 14, such as the insertion sensing sensor 143.

[0163] The control unit 13 can control the overall operation of the aerosol generator 1. In one embodiment, the control unit 13 includes at least one processor. The processor may be embodied as an array of numerous logic gates, or as a combination of a general-purpose microprocessor and memory storing a program executable by the microprocessor. It will be understood by those ordinary skill in the art to which this embodiment belongs that it may also be embodied by other forms of hardware.

[0164] The control unit 13 can control the temperature of the stick heater 15 by controlling the supply of power from the battery 12 to the stick heater 15. The control unit 13 can control the temperature of the cartridge heater 15 and / or the stick heater 15 based on the temperature of the cartridge heater 15 and / or the stick heater 15 sensed by the temperature sensor 141. The control unit 13 can adjust the power supplied to the cartridge heater 15 and / or the stick heater 15 based on the temperature of the cartridge heater 15 and / or the stick heater 15. For example, the control unit 13 can determine a target temperature for the cartridge heater 15 and / or the stick heater 15 based on a temperature profile stored in the memory 60.

[0165] The aerosol generator 1 may include a power supply circuit (not shown) electrically connected to the battery 12 between the battery 12 and the cartridge heater 15 and / or the stick heater 15. The power supply circuit may be electrically connected to the cartridge heater 15, the stick heater 15, or the induction coil 181. The power supply circuit includes at least one switching element. The switching element is embodied by a bipolar junction transistor (BJT), a field-effect transistor (FET), etc. The control unit 13 can control the power supply circuit.

[0166] The control unit 13 can control the power supply by controlling the switching of the switching elements in the power supply circuit. The power supply circuit is also an inverter that converts the DC power output from the battery 12 into AC power. For example, the inverter is composed of a full-bridge circuit or a half-bridge circuit that includes multiple switching elements.

[0167] The control unit 13 can turn on the switching element so that power is supplied from the battery 12 to the cartridge heater 15 and / or the stick heater 15. The control unit 13 can turn off the switching element so that the power supply to the cartridge heater 15 and / or the stick heater 15 is cut off. The control unit 13 can adjust the current supplied from the battery 12 by adjusting the frequency and / or duty cycle of the current pulse input to the switching element.

[0168] The control unit 13 can control the voltage output from the battery 12 by controlling the switching of the switching elements in the power supply circuit. The power conversion circuit can convert the voltage output from the battery 12. For example, the power conversion circuit includes a buck converter that steps down the voltage output from the battery 12. For example, the power conversion circuit is implemented through a buck-boost converter, a Zener diode, etc.

[0169] The control unit 13 can control the on / off operation of the switching element included in the power conversion circuit and adjust the level of the voltage output from the power conversion circuit. When the switching element remains in the on state, the level of the voltage output from the power conversion circuit corresponds to the level of the voltage output from the battery 12. The duty cycle for the on / off operation of the switching element corresponds to the ratio of the voltage output from the power conversion circuit to the voltage output from the battery 12. The lower the duty cycle for the on / off operation of the switching element, the lower the level of the voltage output from the power conversion circuit may be. The stick heater 15 can be heated based on the voltage output from the power conversion circuit.

[0170] The control unit 13 can control the supply of power to the stick heater 15 using at least one of the following methods: pulse width modulation (PWM) and proportional-integral-differential (PID).

[0171] For example, the control unit 13 can use a PWM method to control the supply of current pulses having a predetermined frequency and duty cycle to the stick heater 15. The control unit 13 can adjust the frequency and duty cycle of the current pulses to control the power supplied to the stick heater 15.

[0172] For example, the control unit 13 can determine a target temperature for control based on the temperature profile. The control unit 13 can control the power supplied to the stick heater 15 using a PID method, which is a feedback control method that uses the difference between the temperature of the stick heater 15 and the target temperature, the integral of the difference over time, and the derivative of the difference over time.

[0173] The control unit 13 can prevent the cartridge heater 15 and / or stick heater 15 from overheating. For example, the control unit 13 can control the operation of the power conversion circuit so that the power supply to the cartridge heater 15 and / or stick heater 15 is interrupted based on the temperature of the cartridge heater 15 and / or stick heater 15 exceeding a predetermined limit temperature. For example, the control unit 13 can reduce the amount of power supplied to the cartridge heater 15 and / or stick heater 15 by a certain percentage based on the temperature of the cartridge heater 15 and / or stick heater 15 exceeding a predetermined limit temperature. For example, the control unit 13 can determine that the aerosol-generating material contained in the cartridge 19 has been exhausted based on the temperature of the cartridge heater 15 exceeding a limit temperature and cut off the power supply to the cartridge heater 15.

[0174] The control unit 13 can control the charging and discharging of the battery 12. The control unit 13 can check the temperature of the battery 12 based on the output signal of the temperature sensor 141.

[0175] When a power line is connected to the main body electrode of the aerosol generator 1, the control unit 13 can check whether the temperature of the battery 12 is equal to or above a first limiting temperature, which is the criterion for shutting off the charging of the battery 12. If the temperature of the battery 12 is below the first limiting temperature, the control unit 13 can control the charging of the battery 12 based on a predetermined charging current. If the temperature of the battery 12 is equal to or above the first limiting temperature, the control unit 13 can shut off the charging of the battery 12.

[0176] With the aerosol generator 1 powered on, the control unit 13 can check whether the temperature of the battery 12 is above the second limit temperature, which is the criterion for shutting off the discharge of the battery 12. If the temperature of the battery 12 is below the second limit temperature, the control unit 13 can control the system to use the power stored in the battery 12. If the temperature of the battery 12 is above the second limit temperature, the control unit 13 can interrupt the use of the power stored in the battery 12.

[0177] The control unit 13 can calculate the remaining capacity of the battery 12 relative to the power stored in the battery. For example, the control unit 13 can calculate the remaining capacity of the battery 12 based on the voltage and / or current sensing values ​​of the battery 12.

[0178] The control unit 13 can determine whether or not a stick is inserted into the insertion space via the insertion sensing sensor 143. Based on the output signal of the insertion sensing sensor 143, the control unit 13 can determine that a stick has been inserted. If it determines that a stick has been inserted into the insertion space, the control unit 13 can control the supply of power to the cartridge heater 15 and / or the stick heater 15. For example, the control unit 13 can supply power to the cartridge heater 15 and / or the stick heater 15 based on a temperature profile stored in the memory 60.

[0179] The control unit 13 can determine whether or not the stick has been removed from the insertion space. For example, the control unit 13 can determine whether or not the stick has been removed from the insertion space through the insertion sensing sensor 143. For example, the control unit 13 can determine that the stick has been removed from the insertion space if the temperature of the stick heater 15 is above a limit temperature, or if the temperature change gradient of the stick heater 15 is above a set gradient. If the control unit 13 determines that the stick has been removed from the insertion space, it can cut off the power supply to the cartridge heater 15 and / or the stick heater 15.

[0180] The control unit 13 can control the power supply time and / or power supply amount to the stick heater 15 based on the state of the stick sensed by the sensor unit 14. The control unit 13 can determine the level range that includes the level of the capacitance sensor signal based on a lookup table. The control unit 13 can determine the amount of moisture in the stick based on the determined level range.

[0181] If the stick is in an over-humidified state, the control unit 13 can control the power supply time to the stick heater 15, increasing the preheating time of the stick compared to normal conditions.

[0182] The control unit 13 can determine whether the stick inserted into the insertion space is to be reused through the reuse sensing sensor 144. For example, the control unit 13 can compare the sensing value of the reuse sensing sensor signal with a first reference range that includes a first hue, and if the sensing value falls within the first reference range, it can determine that the stick is not being used. For example, the control unit 13 can compare the sensing value of the reuse sensing sensor signal with a second reference range that includes a second hue, and if the sensing value falls within the second reference range, it can determine that the stick has been used. If it is determined that the stick has been used, the control unit 13 can cut off the power supply to the cartridge heater 15 and / or the stick heater 15.

[0183] The control unit 13 can determine whether to connect and / or remove the cartridge 19 via the cartridge sensing sensor 145. For example, the control unit 13 can determine whether to connect and / or remove the cartridge 19 based on the sensing value of the signal from the cartridge sensing sensor.

[0184] The control unit 13 can determine whether or not the aerosol-generating material in the cartridge 19 has been exhausted. For example, the control unit 13 can preheat the cartridge heater 15 and / or the stick heater 15 by applying power, and determine whether or not the temperature of the cartridge heater 15 exceeds a limit temperature during the preheating period. If the temperature of the cartridge heater 15 exceeds the limit temperature, the control unit 13 can determine that the aerosol-generating material in the cartridge 19 has been exhausted. If the control unit 13 determines that the aerosol-generating material in the cartridge 19 has been exhausted, it can cut off the power supply to the cartridge heater 15 and / or the stick heater 15.

[0185] The control unit 13 can determine whether or not the cartridge 19 can be used. For example, based on the data stored in the memory 60, the control unit 13 can determine that the cartridge 19 cannot be used if the current number of puffs is greater than or equal to the maximum number of puffs set for the cartridge 19. For example, the control unit 13 can determine that the cartridge 19 cannot be used if the total time the cartridge heater 15 has been heated is greater than or equal to a predetermined maximum time, or if the total amount of power supplied to the cartridge heater 15 is greater than or equal to a predetermined maximum amount of power.

[0186] The control unit 13 can make decisions regarding the user's inhalation through the puff sensor 142. For example, the control unit 13 can determine whether or not a puff has occurred based on the sensing value of the signal from the puff sensor. For example, the control unit 13 can determine the intensity of the puff based on the sensing value of the signal from the puff sensor 142. If the number of puffs reaches a predetermined maximum number of puffs, or if no puff is detected for a predetermined time or longer, the control unit 13 can cut off the power supply to the cartridge heater 15 and / or the stick heater 15.

[0187] The control unit 13 can determine whether the cap is attached and / or removed via the cap sensing sensor 146. For example, the control unit 13 can determine whether the cap is attached and / or removed based on the sensing value of the signal from the cap sensing sensor.

[0188] The control unit 13 can control the output unit 40 based on the results sensed by the sensor unit 14. For example, if the number of puffs counted through the puff sensor 142 reaches a predetermined number, the control unit 13 can notify the user that the aerosol generator 1 will soon shut off through at least one of the display unit 41, the haptic unit 42, and the acoustic output unit 43. For example, the control unit 13 can notify the user through the output unit 40 based on the determination that there is no stick in the insertion space. For example, the control unit 13 can notify the user through the output unit 40 based on the determination that the cartridge 19 and / or cap is not installed. For example, the control unit 13 can transmit information about the temperature of the cartridge heater 15 and / or stick heater 15 to the user through the output unit 40.

[0189] The control unit 13 can save and update a history of events in the memory 60 based on the occurrence of a predetermined event.

The history of events includes the date and time the event occurred, log data corresponding to the event, etc. For example, if a predetermined event is the detection of stick insertion, the log data corresponding to the event includes data such as the sensing value of the insertion detection sensor 143. For example, if a predetermined event is the detection of overheating in the cartridge heater 15 and / or the stick heater 15, the log data corresponding to the event will include data on the temperature of the cartridge heater 15 and / or the stick heater 15, the voltage applied to the cartridge heater 15 and / or the stick heater 15, and the current flowing through the cartridge heater 15 and / or the stick heater 15.

The user can perform user authentication through the external device. The external device can determine whether the user data is valid based on the user's date of birth, a unique number identifying the user, etc., and can receive data regarding the right to use the aerosol generator 1 from an external server. Based on the data regarding the right to use, the external device can transmit data indicating the completion of user authentication to the aerosol generator 1. Once user authentication is complete, the control unit 13 can remove the restriction on the use of at least one function of the aerosol generator 1.
