[0002] Recently, there has been a growing demand for technologies that replace the conventional method of producing aerosols by burning cigarettes. For example, research is underway into methods for producing aerosols from liquid or solid aerosol-generating substances, or for producing vapor from liquid aerosol-generating substances and then passing the vapor through a solid flavoring medium to produce a flavored aerosol.

[0003] The aerosol generating device may be powered by a battery. The battery may be a battery detachable from the aerosol generating device. The aerosol generating device may include a battery coupling portion capable of accommodating the detachable battery, and a battery cover that selectively opens or closes the battery coupling portion.

[0004] Meanwhile, if the aerosol generator's battery is configured as a removable battery, water may infiltrate the device during the insertion and removal of the removable battery. Since the electrodes that contact the removable battery are exposed, if water that has infiltrated the device comes into contact with the electrodes, it could cause internal components to malfunction due to overcurrent and overvoltage.

[0005] Liquid can penetrate the gap between the battery cover and other components used to open or close the battery connection of an aerosol generating device. Liquid penetrating through the gap between the battery cover and other components can flow into other components and cause electrical problems.

However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein.

[0063] FIG. 1 is a perspective view illustrating an aerosol generating device according to one embodiment of the present disclosure.

[0064] The aerosol generating device (1) can generate an aerosol and provide the generated aerosol to the outside.

[0065] An aerosol generating device (1) may include a main body (10). The main body (10) forms the overall appearance of the aerosol generating device (1) and may include a space therein. At least one of an article receiving portion (11), an aerosol generator (not shown), a control portion (not shown), and a battery (not shown) may be placed inside the main body (10).

[0066] The article receiving portion (11) may provide a space into which an aerosol-generating article (2) may be detachably coupled (inserted). The aerosol-generating article (2) may include an aerosol-generating material that is heated by a heater to generate an aerosol. The article receiving portion (11) may provide a space open toward the outside of the main body (10) so that the aerosol-generating article (2) may be inserted.

[0067] The article receiving portion (11) may be sunken toward the inside of the main body (10) so that at least a portion of the aerosol-generating article (2) can be inserted.

[0072] As another example, a susceptor may be included inside the aerosol-generating article (2). The susceptor inside the aerosol-generating article (2) may be heated by a magnetic field generated by an alternating current flowing through an induction coil. The susceptor may be disposed inside the aerosol-generating article (2) and may not be electrically connected to the aerosol-generating device. The susceptor may be inserted into the article receiving portion (11) together with the aerosol-generating article (2) and may be removed from the article receiving portion (11) together with the aerosol-generating article (2).

For example, the display can be in the form of an LED light-emitting element. For example, the display can be a liquid crystal display panel (LCD), an organic light-emitting display panel (OLED), etc.

[0077] The acoustic output unit can provide information about the aerosol generating device (1) to the user audibly. For example, the acoustic output unit can convert an electrical signal into an acoustic signal and output it externally.

[0084] For example, referring to FIG. 3, the aerosol generating device (1) may include an induction coil (151) surrounding the aerosol generator (15). The induction coil (151) may heat the aerosol generator (15). The aerosol generator (15) may be heated by a magnetic field generated by an AC current flowing through the induction coil (151) as a susceptor. The magnetic field may penetrate the aerosol generator (15) and generate an eddy current within the aerosol generator (15). The eddy current may generate heat in the aerosol generator (15).

[0085] For example, referring to FIG. 4, a susceptor (152) may be included inside the aerosol generating article (2), and the susceptor (152) inside the aerosol generating article (2) may be heated by a magnetic field generated by an AC current flowing through an induction coil (151).

[0088] The control unit (13) can analyze the results detected by the sensor unit (14) and control the processes to be performed thereafter. For example, the control unit (13) can control the power supplied to the aerosol generator (15) so that the operation of the aerosol generator (15) is started or ended based on the results detected by the sensor unit (14). For example, the control unit (13) can control the amount of power supplied to the aerosol generator (15) and the time for which the power is supplied so that the aerosol generator (15) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor unit (14).

For example, the control unit (13) can control the power supplied to the generation unit (32) so that the operation of the generation unit (32) can be started or ended based on the results detected by the sensor. For example, the control unit (13) can control the amount of power supplied to the generation unit (32) and the time for which the power is supplied so that the generation unit (32) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the results detected by the sensor.

[0103] The battery (12) can supply power to components of the aerosol generating device (1). For example, the battery (12) can provide electrical energy to at least one of the control unit (13), the sensor unit (not shown), and the aerosol generator (not shown).

[0104] The sensor unit may include at least one of a temperature sensor, a puff sensor, a cartridge detection sensor, and a movement detection sensor. For example, the sensor unit may sense at least one of the temperature of the generation unit (32), the temperature of the battery (12), and the temperature inside and outside the main body (10). For example, the sensor unit may sense the user's puff. For example, the sensor unit may sense whether the cartridge (3) is mounted. For example, the sensor unit may sense the movement of the aerosol generation device (1).

[0105] Fig. 7 is a drawing for explaining an aerosol generating device according to one embodiment of the present disclosure. Fig. 7 is a perspective view for explaining in detail the configurations of the aerosol generating device (1).

[0106] The aerosol generating device (1) of the present embodiment may include the same configuration as the aerosol generating device (1) of any one of the embodiments described with reference to FIGS. 1 to 6, but is not limited thereto.

[0107] The aerosol generating device (1) may include a main body (10). The main body (10) may form an outer appearance and include a space inside.

[0108] The aerosol generating device (1) may further include a battery coupling portion (16) and a battery cover (17).

[0109] A battery (not shown) capable of supplying power can be detachably connected to the battery coupling portion (16). The battery coupling portion (16) may include a space for connecting the battery (not shown). The battery coupling portion (16) may be arranged in an area inside the main body (10). A main body electrode (not shown) for electrically connecting to the battery may be arranged inside the battery coupling portion (16).

[0110] The main body (10) may include a battery cover (17) that can selectively open or close the battery coupling portion (16). The battery cover (17) may be placed in an area of ​​the main body (10). For example, the battery cover (17) may be placed in an area corresponding to the battery coupling portion (16).

[0111] The battery cover (17) can be detachably connected to the main body (10). The battery cover (17) can selectively open or close the battery connection portion (16).

[0112] For example, the battery cover (17) can be moved to a closed position that closes the battery coupling portion (16) so that the battery coupling portion (16) can be closed from the outside. The battery cover (17) can be moved out of the closed position so that the battery coupling portion (16) can be opened toward the outside.

[0113] The battery cover (17) can be coupled to the main body (10) in a closed position that closes the battery coupling portion (16). The battery cover (17) can be separated from the main body (10) by moving out of the closed position.

[0114] Fig. 7 illustrates a battery cover (17) separated from the main body (10) moving toward the closed position. Arrow A indicates the direction in which the battery cover (17) moves toward the closed position.

[0115] Referring to Fig. 7, the battery cover (17) can be moved to a closed position by moving in the -x direction, thereby closing the battery coupling portion (16). When the battery cover (17) is moved to the closed position, the battery coupling portion (16) is closed by the battery cover (17) and is not exposed to the outside of the aerosol generating device (1).

[0116] The battery cover (17) positioned in the closed position can be moved in the +x direction (opposite direction of arrow A) to open the battery coupling portion (16). When the battery cover (17) is moved in the +x direction from the closed position, the battery coupling portion (16) opens toward the outside and is exposed to the outside of the aerosol generating device (1).

[0117] When the battery cover (17) is moved to the closed position and combined with the main body (10), the battery coupling portion (16) is closed to the outside, and a battery (not shown) cannot be combined or separated from the battery coupling portion (16), and foreign substances from the outside of the aerosol generating device (1) can be prevented from entering the battery coupling portion (16).

[0118] When the battery cover (17) is separated from the main body (10), the battery coupling portion (16) opens toward the outside, so that the battery can be coupled to the battery coupling portion (16) or removed from the battery coupling portion (16).

[0119] The direction in which the battery connection portion (16) is opened (-y) and the position in which the battery cover (17) is positioned, as shown in Fig. 7, are merely examples. The battery connection portion (16) may be opened on a side of the main body (10) other than the -y direction, and the position in which the battery cover (17) is positioned may be determined depending on the direction in which the battery connection portion (16) is opened.

[0120] At least a portion of the main body (10), the battery coupling portion (16), and the battery cover (17) may be provided with a structure for detachable coupling of the main body (10) and the battery cover (17). For example, the battery cover (17) may be provided with a hook structure, and the main body (10) may be provided with a groove into which the hook structure can be caught. As another example, the main body (10) may be provided with a groove into which the battery cover (17) can slide. As another example, the main body (10) or the battery cover (17) may be provided with a button structure that allows the battery cover (17) to be detached from the main body (10) by a pressurized operation. As another example, the main body (10) and the battery cover (17) may be detachably coupled by screws and screw threads. As another example, the main body (10) and the battery cover (17) may be detachably coupled by an electronic method. The configuration and structure that enable the main body (10) and the battery cover (17) to be detachably combined are not limited to those described above.

[0121] However, according to the structure of the battery cover (17) that is detachable from the main body (10) and selectively opens or closes the battery coupling portion (16) for the detachable battery, liquid may penetrate into the gap between the battery cover (17) and the main body (10).

[0122] Liquid that has penetrated through the gap between the battery cover (17) and the main body (10) may flow into the battery joint (16) and cause problems with the power supply of the battery. Liquid that has penetrated through the gap between the battery cover (17) and the main body (10) may flow into other components inside the main body (10) and cause electrical problems.

[0123] A sealing member (not shown) may be placed between the main body (10) and the battery cover (17). The sealing member may prevent liquid from penetrating between the main body (10) and the battery cover (17) toward the battery joint (16). The sealing member may include silicone, rubber, plastic, etc., and the material thereof is not limited.

[0124] According to the present disclosure, in order to prevent problems that may arise due to liquid penetration through the gap between the main body (10) and the battery cover (17), a configuration capable of early detecting liquid penetrating between the battery cover (17) and the main body (10) may be further included.

[0125] For example, the aerosol generating device (1) may further include a liquid sensor (not shown). The liquid sensor may be included in the sensor unit. The liquid sensor may detect liquid that has penetrated between the main body (10) and the battery cover (17) and generate a signal depending on whether liquid is detected.

[0126] For example, the liquid sensor can detect when water seeps between the main body (10) and the battery cover (17) and generate a signal. The control unit (not shown) can control the aerosol generating device (1) in response to the signal generated by the liquid sensor.

[0127] At least one of the main body (10) and the battery cover (17) may include a groove in which a liquid sensor may be placed. For example, referring to FIG. 7, the main body (10) may include a first groove (101), and the battery cover (17) may include a second groove (171).

[0128] A liquid sensor may be placed in at least one of the first groove (101) and the second groove (171). For example, a liquid sensor may be placed in each of the first groove (101) and the second groove (171).

[0129] For example, when the battery cover (17) is combined with the main body (10), the first groove (101) and the second groove (171) can be arranged to face each other.

[0130] Hereinafter, with reference to FIG. 8, detection of liquid penetrating between the main body (10) and the battery cover (17) through a liquid sensor and various embodiments based thereon are described.

[0131] FIG. 8 is a drawing for explaining an aerosol generating device according to one embodiment of the present disclosure.

[0132] The aerosol generating device (1) of the present embodiment may include the same configuration as the aerosol generating device (1) of any one of the embodiments described with reference to FIGS. 1 to 6, but is not limited thereto.

[0133] Fig. 8 is a schematic cross-sectional view for explaining in detail the configurations related to the battery coupling portion (16) and battery cover (17) of the aerosol generating device (1) illustrated in Fig. 7. Fig. 8 is a cross-sectional view taken along the VII-VII cutting line of Fig. 7.

[0134] Fig. 7 is a perspective view showing a state in which the battery cover (17) is moved to the closed position, and Fig. 8 is a cross-sectional view showing a state in which the battery cover (17) is placed in the closed position.

[0135] The aerosol generating device (1) and the components included therein described with reference to FIG. 8 may have the same or similar configurations as the aerosol generating device (1) and the components included therein described with reference to FIG. 7, and descriptions of overlapping components may be omitted to avoid repeated descriptions.

[0136] Referring to Fig. 8, the battery (12) can be accommodated in the battery coupling portion (16). As described above with reference to Fig. 7, the battery coupling portion (16) can be opened or closed by the battery cover (17).

[0137] The battery (12) can be inserted into the inside of the battery coupling portion (16) or discharged to the outside of the battery coupling portion (16) when the battery coupling portion (16) is opened.

[0138] After the battery (12) is inserted into the inside of the battery coupling portion (16), when the battery cover (17) is moved to the closed position and the battery coupling portion (16) is closed, the battery (12) can be fixed inside the battery coupling portion (16).

[0139] Describing the state shown in Fig. 8, the battery (12) is placed inside the battery coupling portion (16), the battery cover (17) is in the closed position, and the battery cover (17) closes the battery coupling portion (16) so that the battery (12) is not discharged to the outside.

[0140] The battery coupling unit (16) may be arranged in an area inside the main body (10). A main body electrode (161) may be arranged in an area inside the battery coupling unit (16). The main body electrode (161) is configured to be electrically connected to the battery (12). The main body electrode (161) may receive current from the battery (12) and transmit the current to other components of the aerosol generating device (1). For example, at least some of the control unit (13), the sensor unit (14), and the aerosol generator (15) may receive current from the battery (12) through the main body electrode (161).

[0141] A battery electrode (121) may be placed in one area of ​​the battery (12). The battery electrode (121) is configured to be electrically connected to the main body electrode (161). The battery electrode (121) may supply current to other components of the aerosol generating device (1) through the main body electrode (161).

[0142] When the battery cover (17) is separated from the main body (10), the battery (12) can be separated from the battery coupling portion (16). When the battery (12) is separated from the battery coupling portion (16), the electrical connection between the battery electrode (121) and the main body electrode (161) is broken, and the power supply to the battery (12) can be interrupted.

[0143] According to the present disclosure, it is possible to prevent problems that may arise from liquid penetration through the gap between the main body (10) and the battery cover (17).

[0144] For example, the aerosol generating device (1) may further include a liquid sensor (141). The liquid sensor (141) may be included in the sensor section described above. The liquid sensor (141) may detect liquid that has penetrated between the main body (10) and the battery cover (17), and generate a signal depending on whether liquid is detected.

[0145] For example, the liquid sensor (141) can detect water that has seeped between the main body (10) and the battery cover (17) and generate a signal depending on whether water has been detected. The control unit (13) can control other components of the aerosol generating device (1) in response to the signal generated by the liquid sensor.

[0146] The liquid sensor (141) may include a 'pad', which is an electrode having electrical conductivity. The liquid sensor (141) may generate a signal according to a change that occurs when the pad comes into contact with a liquid such as water. The liquid sensor (141) may include one or more pads.

[0147] For example, the liquid sensor (141) may include a first pad (141a) and a second pad (141b). The first pad (141a) and the second pad (141b) may each have electrical conductivity and may be positioned facing each other at a predetermined distance apart.

[0148] At least one of the main body (10) and the battery cover (17) may include a groove in which a liquid sensor (141) may be placed. For example, referring to FIG. 8, the main body (10) may include a first groove (101), and the battery cover (17) may include a second groove (171).

[0149] A liquid sensor (141) may be placed in at least one of the first groove (101) and the second groove (171). For example, a first pad (141a) may be placed in the first groove (101), and a second pad (141b) may be placed in the second groove (171). The first pad (141a) may be placed in the main body (10), and the second pad (141b) may be placed in the battery cover (17).

[0150] However, according to the technical idea of ​​the present disclosure, the arrangement of the liquid sensor (141) is not limited to that described above.

[0151] According to the present disclosure, the aerosol generating device (1) may include an output unit (not shown). The output unit may output information related to the aerosol generating device (1) and provide it to a user. The output unit may include at least one of a display and an audio output unit, but is not limited thereto.

[0152] The display can output visual information to the outside. The display can provide information about the aerosol generating device (1) to the user in a visual manner.

[0153] The acoustic output unit can provide information about the aerosol generating device (1) to the user in an auditory manner. For example, the acoustic output unit can convert an electrical signal into an acoustic signal and output it externally.

[0154] The aerosol generating device (1) may further include a memory (not shown). The memory is hardware that stores various data processed within the aerosol generating device (1), and can store data processed by the control unit (13) and data to be processed.

[0155] For example, the liquid sensor (141) may not generate a separate signal when no liquid is detected, but may generate a signal only when liquid is detected. As another example, the liquid sensor (141) may generate a first signal when no liquid is detected, and may generate a second signal different from the first signal when liquid is detected.

[0156] The liquid sensor (141) can detect liquid in various ways according to various embodiments as follows.

[0157] According to one embodiment, the signal of the liquid sensor (141) may be an electrical resistance value. The liquid sensor (141) may include an electrical resistor (not shown). The electrical resistor may be placed in a space where liquid that has penetrated between the main body (10) and the battery cover (17) can flow.

[0158] When a liquid such as water comes into contact with an electrical resistor, its electrical resistance value may decrease. Therefore, when current is flowing through the electrical resistor, if a liquid that has penetrated between the main body (10) and the battery cover (17) comes into contact with the electrical resistor, its electrical resistance value may decrease. The liquid sensor (141) can generate a signal in response to a change in the electrical resistance value of the electrical resistor.

[0159] For example, when liquid that has penetrated between the main body (10) and the battery cover (17) comes into contact with the first pad (141a) and / or the second pad (141b), the electrical resistance value of the first pad (141a) and / or the second pad (141b) may change, and in response, the liquid sensor (141) may generate a signal regarding the electrical resistance value. According to the present embodiment, when liquid is not detected, the electrical resistance value of the first pad (141a) and / or the second pad (141b) may be referred to as the first signal, and the electrical resistance value of the first pad (141a) and / or the second pad (141b) that has changed due to the detection of liquid may be referred to as the second signal.

[0160] According to another embodiment, the signal of the liquid sensor (141) may be a signal corresponding to whether there is an electrical connection between the first pad (141a) and the second pad (141b). When the battery cover (17) is coupled to the main body (10), the first pad (141a) and the second pad (141b) may be spaced apart from each other by a predetermined distance and may be placed facing each other without being electrically connected. At this time, when the liquid that has penetrated between the main body (10) and the battery cover (17) flows between the first pad (141a) and the second pad (141b), the first pad (141a) and the second pad (141b) may be electrically connected through the liquid, and the liquid sensor (141) may generate a signal due to the electrical connection between the first pad (141a) and the second pad (141b). According to this embodiment, the liquid sensor (141) may not generate a separate signal when liquid is not detected, but may generate a signal only when liquid is detected.

[0161] According to another embodiment, the signal of the liquid sensor (141) may be a signal corresponding to the electric capacity between the first pad (141a) and the second pad (141b). The liquid sensor (141) may further include an electric capacity sensor (not shown). When the battery cover (17) is coupled to the main body (10), the first pad (141a) and the second pad (141b) may be spaced apart from each other by a predetermined distance and may be arranged to face each other. At this time, if the liquid that has penetrated between the main body (10) and the battery cover (17) flows between the first pad (141a) and the second pad (141b), the electric capacitance between the first pad (141a) and the second pad (141b) may change, and the liquid sensor (141) may generate a signal in response to the change in the electric capacitance between the first pad (141a) and the second pad (141b). According to the present embodiment, when the liquid is not detected, the signal regarding the electric capacitance between the first pad (141a) and the second pad (141b) that has changed due to the detection of the liquid may be referred to as the second signal.

[0162] According to the present disclosure, the liquid sensor (141) is disposed between the battery cover (17) and the main body (10), so that it can detect liquid between the battery cover (17) and the main body (10) early before it flows into other components and generate a signal, and the control unit (13) can appropriately control the aerosol generating device (1) to prevent damage caused by liquid penetration. Hereinafter, embodiments in which the control unit (13) controls other components in response to a signal received from the liquid sensor (141) will be described.

[0163] The control unit (13) can control other components of the aerosol generating device (1) in response to a signal generated by the liquid sensor (141).

[0164] According to one embodiment of the present disclosure, when the control unit (13) determines that liquid has penetrated between the main body (10) and the battery cover (17) upon receiving a signal regarding liquid penetration from the liquid sensor (141), the control unit (13) can minimize damage caused by the liquid by cutting off the power supply of the battery (12) and stopping all operations of the aerosol generating device (1).

[0165] According to one embodiment of the present disclosure, the control unit (13) can control the display (not shown), the audio output unit (not shown), etc. of the output unit in response to a signal generated by the liquid sensor (141). For example, when the control unit (13) receives a signal regarding the penetration of liquid from the liquid sensor (141), the control unit (13) can control the display to output visual information to separate and / or replace the battery from the aerosol generating device (1). As another example, when the control unit (13) receives a signal regarding the penetration of liquid from the liquid sensor (141), the control unit (13) can control the display to output visual information to stop using the aerosol generating device (1) and cut off the power.

[0166] According to one embodiment of the present disclosure, the control unit (13) can control the acoustic output unit (not shown) of the output unit in response to a signal generated by the liquid sensor (141). For example, when the control unit (13) receives a signal regarding the penetration of liquid from the liquid sensor (141), the control unit (13) can control the acoustic output unit to output auditory information to separate and / or replace the battery from the aerosol generating device (1). For another example, when the control unit (13) receives a signal regarding the penetration of liquid from the liquid sensor (141), the control unit (13) can control the acoustic output unit to output auditory information to stop using the aerosol generating device (1) and cut off the power. For another example, when the control unit (13) receives a signal regarding the penetration of liquid from the liquid sensor (141), the control unit (13) can control the acoustic output unit to output a warning sound.

[0167] According to one embodiment of the present disclosure, the control unit (13) can store information corresponding to a signal generated by the liquid sensor (141) in memory. The information stored in the memory can be helpful in analyzing the cause of a problem that occurs in the future due to liquid in the aerosol generating device (1).

[0168] The embodiments of the present disclosure described above may be combined in a composite manner.

[0169] For example, the control unit (13) can minimize damage caused by liquid by first controlling the display to output visual information regarding liquid penetration, then storing the related information in memory, and automatically cutting off the power supply of the battery (12) after a predetermined period of time has elapsed and stopping all operations of the aerosol generating device (1).

[0170] As another example, the control unit (13) can minimize damage caused by liquid by first controlling the sound output unit to output auditory information regarding the penetration of liquid, then storing the related information in memory, and automatically cutting off the power supply of the battery (12) after a predetermined period of time has elapsed and stopping all operations of the aerosol generating device (1).

[0238] The control unit (13) can control the on / off operation of the switching element included in the power conversion circuit to adjust the level of the voltage output from the power conversion circuit. When the on state of the switching element continues, the level of the voltage output from the power conversion circuit may correspond to the level of the voltage output from the battery (12). The duty ratio for the on / off operation of the switching element may correspond to the ratio of the voltage output from the power conversion circuit to the voltage output from the battery (12). As the duty ratio for the on / off operation of the switching element decreases, the level of the voltage output from the power conversion circuit may decrease. The stick aerosol generator (15) can be heated based on the voltage output from the power conversion circuit.

[0239] The control unit (13) can control power to be supplied to the stick aerosol generator (15) using at least one of a pulse width modulation (PWM) method and a proportional-integral-differential (PID) method.

For example, the control unit (13) can determine that the stick is removed from the insertion space when the temperature of the stick aerosol generator (15) is higher than a limited temperature or when the temperature change slope of the stick aerosol generator (15) is higher than a set slope. When it is determined that the stick is removed from the insertion space, the control unit (13) can cut off the power supply to the cartridge aerosol generator (15) and / or the stick aerosol generator (15).

[0251] The control unit (13) can determine whether the stick inserted into the insertion space has been reused through the reuse detection sensor (145). For example, the control unit (13) can compare the sensing value of the signal of the reuse detection sensor with a first reference range that includes a first color, and if the sensing value is included in the first reference range, it can determine that the stick has not been used. For example, the control unit (13) can compare the sensing value of the signal of the reuse detection sensor with a second reference range that includes a second color, and if the sensing value is included in 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 supply of power to the cartridge aerosol generator (15) and / or the stick aerosol generator (15).

[0252] The control unit (13) can determine whether the cartridge is coupled and / or removed through the cartridge detection sensor (146). For example, the control unit (13) can determine whether the cartridge is coupled and / or removed based on the sensing value of the signal of the cartridge detection sensor.

[0253] The control unit (13) can determine whether the aerosol generating material of the cartridge is exhausted. For example, the control unit (13) can preheat the cartridge aerosol generator (15) and / or the stick aerosol generator (15) by applying power, and determine whether the temperature of the cartridge aerosol generator (15) exceeds a limited temperature during the preheating period. If the temperature of the cartridge aerosol generator (15) exceeds the limited temperature, it can be determined that the aerosol generating material of the cartridge is exhausted. If it is determined that the aerosol generating material of the cartridge is exhausted, the control unit (13) can cut off the supply of power to the cartridge aerosol generator (15) and / or the stick aerosol generator (15).

[0254] The control unit (13) can determine whether the cartridge is usable. For example, the control unit (13) can determine that the cartridge is unusable if the current number of puffs is greater than or equal to the maximum number of puffs set for the cartridge based on data stored in the memory (60). For example, the control unit (13) can determine that the cartridge is unusable if the total time that the cartridge aerosol generator (15) has been heated is greater than or equal to the preset maximum time or the total amount of power supplied to the cartridge aerosol generator (15) is greater than or equal to the preset maximum amount of power.

[0255] The control unit (13) can make a judgment regarding the user's inhalation through the puff sensor (143). For example, the control unit (13) can determine whether a puff is generated based on the sensing value of the signal of the puff sensor. For example, the control unit (13) can determine the intensity of the puff based on the sensing value of the signal of the puff sensor (143). When the number of puffs reaches a preset maximum number of puffs or when no puffs are detected for a preset time or longer, the control unit (13) can cut off the supply of power to the cartridge aerosol generator (15) and / or the stick aerosol generator (15).

[0267] The aerosol generating device (1) can generate and provide an aerosol.

[0268] The aerosol generating device (1) may include a main body (10). The main body (10) forms the overall appearance of the aerosol generating device (1) and may include a space therein.

A removable battery (110 of FIG. 15) may be detachably mounted on the aerosol generating device (1). When a removable battery (12) is inserted into the aerosol generating device (1), the removable battery (12) can be defined as an internal configuration of the aerosol generating device (1).

[0269] The article receiving portion (11) may provide a space into which an aerosol-generating article (2) may be detachably coupled (inserted). The aerosol-generating article (2) may include an aerosol-generating material that is heated by an aerosol generator (15) to generate an aerosol. The article receiving portion (11) may provide a space open toward the outside of the main body (10) so that the aerosol-generating article (2) may be inserted.

[0270] The article receiving portion (11) may be sunken toward the inside of the main body (10) so that at least a portion of the aerosol-generating article (2) can be inserted. The depth to which the article receiving portion (11) is sunken may correspond to the length of a region of the aerosol-generating article (2) containing an aerosol-generating substance and / or medium.

For example, the cover (18) may open the article receiving portion (11) at a first position so that the article receiving portion (11) is exposed to the outside, thereby allowing an aerosol generating article (2) to be inserted into the article receiving portion (11). In addition, the cover (18) may move from the first position to a second position and close the article receiving portion (11) so that the article receiving portion (11) is not exposed to the outside, thereby protecting the article receiving portion (11) from external impact or the inflow of external foreign substances.

The aerosol generator (15) may have a configuration corresponding to the aerosol generators (15a, 15b, 15c, 15d, 15e) of FIGS. 12a to 12e.

[0274] A removable battery (12) can supply power to operate components of an aerosol generating device (1). The removable battery (12) can be accommodated inside the main body (10) through a battery coupling portion (16 of FIG. 13). In some embodiments, the aerosol generating device (1) may further include an internal battery (19) that is distinct from the removable battery (12) and fixed inside the main body (10). The internal battery (19) has a lower output than the removable battery (12), and can provide a minimum amount of power to the internal components of the aerosol generating device (1) even when the removable battery (12) is not accommodated in the battery coupling portion (16).

[0275] The control unit (13) can control the overall operation of the aerosol generating device (1). The control unit (13) can be mounted on a printed circuit board (PCB). The control unit (13) can receive user input through the input unit (70) and control the operation of the aerosol generator (15) based on the user input. In addition, the control unit (13) can control the output unit (40) to output status information of the aerosol generating device (1).

[0276] The input unit (70) can receive user input. In one embodiment, the input unit (70) can be configured as a pressure-type push button or a touch sensor. The input unit (70) can be positioned to protrude from at least a portion of the outer surface of the main body (10), and can receive user input in response to the user's pressure or touch on the input unit (70).

The output unit (40) can be arranged in at least a portion of the outer circumferential surface of the main body (10). Although FIG. 11 illustrates that the output unit (40) is arranged in the -z direction with respect to the input unit (70), the position of the output unit (40) is not limited thereto.

[0278] FIGS. 12A to 12E are drawings illustrating embodiments of the aerosol generating device of FIG. 11 implemented in various types.

[0279] Referring to FIGS. 12a to 12e, the aerosol generating device (1) can be implemented as various types of aerosol generating devices (1a to 1e), such as those using an electric resistance heating method or an induction heating method, those additionally equipped with a vaporizer, and those using a cartridge method. Only some elements for explaining the types of aerosol generating devices (1a to 1e) are illustrated in FIGS. 12a to 12e, and other general elements may be further included in the aerosol generating devices (1a to 1e) in addition to the elements illustrated in FIGS. 12a to 12e.

[0280] In Fig. 12a, the aerosol generating device (1a) may include a removable battery (12), an aerosol generator (15a), and a control unit (13).

[0281] A cigarette (2a) can be inserted into the receiving space inside the aerosol generating device (1a). When the cigarette (2a) is inserted into the aerosol generating device (1a), the aerosol generating device (1a) can generate an aerosol from the cigarette (2a) by heating the cigarette (2a) using the aerosol generator (15a). The generated aerosol can be delivered to the user through the cigarette (2a).

[0282] The aerosol generator (15a) can be heated by power supplied from a removable battery (12). The aerosol generator (15a) can be an electrical resistive heater. For example, the aerosol generator (15a) includes an electrically conductive track, and the aerosol generator (15a) can be heated as current flows through the electrically conductive track.

[0283] The electrically conductive track of the aerosol generator (15a) is made of an electrically resistive material, so that the heating temperature can be determined according to the power consumption of the resistor, and the resistance value of the electrically conductive track can be set based on the power consumption of the resistor of the electrically conductive track. The resistance value of the electrically conductive track can be set in various ways depending on the constituent material, length, width, thickness, or pattern of the electrically resistive material.

[0284] The electrically conductive track may exhibit an increase in internal resistance as the temperature increases, depending on its temperature coefficient of resistance characteristics. For example, the temperature and resistance of the electrically conductive track may be proportional within a given temperature range. Using this principle, an aerosol generator (15a) manufactured with an electrically conductive track can heat a cigarette (2a) using electrical resistance.

[0285] The electrically conductive tracks can be made of tungsten, gold, platinum, silver, copper, nickel, palladium, or a combination thereof. Additionally, the electrically conductive tracks can be doped with a suitable doping agent and include an alloy.

[0286] The shape of the aerosol generator (15a) can be manufactured in various ways, such as a tube shape, a plate shape, a needle shape, or a rod shape. In addition, a plurality of aerosol generators (15a) can be arranged. The aerosol generator (15a) can be inserted into the interior of the cigarette (2a) and used as an internal heating method to heat the interior of the cigarette (2a).

[0287] The removable battery (12) can be separated from or mounted on the aerosol generating device (1a), and when the removable battery (12) is mounted on the aerosol generating device (1a), power can be supplied from the removable battery (12) to the aerosol generator (15a) for heating operation of the aerosol generator (15a), thereby controlling the temperature of the electrically conductive track.

[0288] The control unit (13) can control the heating operation of the aerosol generator (15a) by controlling the power supplied to the aerosol generator (15a). For example, the control unit (13) can control the temperature at which the cigarette (2a) is heated by the aerosol generator (15a) according to a temperature profile.

[0289] Figures 12b and 12c are drawings for explaining aerosol generating devices (1b, 1c) additionally equipped with vaporizers (155b, 155c) according to exemplary embodiments. Each of the aerosol generating devices (1b, 1c) may be a type of aerosol generating device (1).

[0290] Referring to FIGS. 12b and 12c, the aerosol generating device (1b, 1c) further includes a vaporizer (155b, 155c). A cigarette (2b, 2c) can be inserted into the internal space of the aerosol generating device (1b, 1c).

[0291] In Fig. 12b, the vaporizer (155b) and the aerosol generator (15b) are depicted as being arranged in a row. However, in Fig. 12c, the vaporizer (155c) and the aerosol generator (15c) are depicted as being arranged in parallel. That is, the aerosol generating devices (1b, 1c) can be distinguished depending on the arrangement of the vaporizer (155b).

[0292] The aerosol generator (15b, 15c) can be heated by power supplied from a removable battery (12). The aerosol generator (15b, 15c) is an electrical resistive heater, which may include, for example, electrically conductive tracks.

[0293] Unlike the aerosol generator (15a) described in Fig. 12a, the aerosol generators (15b, 15c) of Figs. 12b and 12c can be implemented in an external heating manner by being placed around the outer periphery of the cigarette (2b, 2c) to heat the outer surface of the cigarette (2b, 2c).

[0294] The vaporizer (155b, 155c) can heat the liquid composition to generate an aerosol, and the generated aerosol can be delivered to the user through the cigarette (2b, 2c). That is, the aerosol generated by the vaporizer (155b, 155c) can be transported along the airflow passage of the aerosol generating device (1b, 1c), and the airflow passage can be configured so that the aerosol generated by the vaporizer (155b, 155c) can be delivered to the user through the cigarette (2b, 2c).

[0295] The vaporizer (155b, 155c) may include a liquid storage unit, a liquid delivery means, and a heating element (or vaporization element). However, each of the liquid storage unit, the liquid delivery means, and the heating element may be positioned as an independent module at a different location within the aerosol generating device (1) rather than within the vaporizer (155b, 155c).

[0296] The liquid reservoir can store a liquid composition. For example, the liquid composition can be a liquid containing a tobacco-containing substance including a volatile tobacco flavoring component, or a liquid containing a non-tobacco substance. The liquid reservoir can be designed to be detachable from / attached to the vaporizer (155b, 155c), or can be designed as an integral part of the vaporizer (155b, 155c). For example, the liquid composition can include water, a solvent, ethanol, a plant extract, a flavoring agent, a flavoring agent, or a vitamin mixture. Additionally, the liquid composition can include an aerosol-forming agent such as glycerin and propylene glycol.

[0297] The liquid delivery means can deliver the liquid composition from the liquid storage to the heating element. For example, the liquid delivery means can be, but is not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0298] The heating element provided in the vaporizer (155b, 155c) is an element for heating (vaporizing) the liquid composition delivered by the liquid delivery means. For example, the heating element may be, but is not limited to, a metal heating wire, a metal heating plate, a ceramic heater, etc. In addition, the heating element may be composed of a conductive filament such as a nichrome wire and may be arranged in a structure that is wound around the liquid delivery means. The heating element may be heated by a current supply and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol may be generated. Accordingly, the vaporizer (155b, 155c) may also be referred to by other terms such as a cartomizer or an atomizer.

[0299] The removable battery (12) can be separated from or mounted on the aerosol generating device (1b, 1c), and when the removable battery (12) is mounted on the aerosol generating device (1b, 1c), power can be supplied from the removable battery (12) to the aerosol generator (15b, 15c) and the vaporizer (155b, 155c) for heating operation of the aerosol generator (15b, 15c) and the vaporizer (155b, 155c).

[0300] The control unit (13) can control the heating operation of the aerosol generators (15b, 15c) and the vaporizers (155b, 155c) by controlling the power supplied to the aerosol generators (15b, 15c) and the vaporizers (155b, 155c). For example, the control unit (13) can control the temperature at which the cigarettes (2b, 2c) are heated by the aerosol generators (15b, 15c) and the vaporizers (155b, 155c) according to the temperature profile.

[0301] FIG. 12d is a drawing for explaining an aerosol generating device (1d) of an induction heating method according to an exemplary embodiment. The aerosol generating device (1d) may be a type of the aerosol generating device (1).

[0302] Referring to FIG. 12d, the aerosol generating device (1d) may include an aerosol generator (15d) including a coil (41d) and a susceptor (152d), a removable battery (12), and a control unit (13).

[0303] The aerosol generating device (1d) can generate an aerosol by heating a cigarette (2d) accommodated in the aerosol generating device (1d) using an induction heating method. The induction heating method may refer to a method of heating a magnetic body that generates heat by applying an alternating magnetic field whose direction changes periodically to the magnetic body that generates heat due to an external magnetic field. Accordingly, the aerosol generating device (1d) can release heat energy from the magnetic body by applying an alternating magnetic field to the magnetic body, and can heat the cigarette (2d) by transferring the heat energy released from the magnetic body to the cigarette. Here, the magnetic body that generates heat due to the external magnetic field may be a susceptor (152d). The susceptor (152d) may be provided in the aerosol generating device (1d). Alternatively, the susceptor (152d) may be provided inside the cigarette (2d) in the shape of a piece, flake, strip, etc. instead of being provided in the aerosol generating device (1d).

[0304] The susceptor (152d) may be formed of a ferromagnetic substance. For example, the material of the susceptor (152d) may include a metal or carbon. The material of the susceptor (152d) may include at least one of ferrite, a ferromagnetic alloy, stainless steel, and aluminum (Al). In addition, the material of the susceptor (152d) may include at least one of a ceramic such as graphite or zirconia, a transition metal such as nickel (Ni) or cobalt (Co), and a metalloid such as boron (B) or phosphorus (P).

[0305] The aerosol generating device (1d) can accommodate a cigarette (2d). A space for accommodating the cigarette (2d) can be formed in the aerosol generating device (1d). A susceptor (152d) can be arranged around the periphery of the space for accommodating the cigarette (2d). For example, the susceptor (152d) can have a cylindrical shape that surrounds the exterior of the cigarette (2d). Therefore, when the cigarette (2d) is accommodated in the aerosol generating device (1d), the cigarette (2d) can be accommodated in the accommodation space of the susceptor (152d), and the susceptor (152d) can be arranged at a position that surrounds at least a portion of the outer surface of the cigarette (2d). However, the shape of the susceptor (152d) is not limited thereto and may vary. For example, the susceptor (152d) may be manufactured in a rod shape to be inserted into the inside of the cigarette (2d).

[0306] The aerosol generator (15d) is an induction heating type, and the aerosol generator (15d) can heat a cigarette (2d) accommodated in the aerosol generator (1d) by using a susceptor (152d) that generates heat by an external magnetic field generated by a coil (41d).

[0307] The coil (41d) is arranged to be wound along the outer surface of the susceptor (152d), so that an alternating magnetic field can be applied to the susceptor (152d). When power is supplied to the coil (41d) from the aerosol generating device (1d), a magnetic field can be formed in the internal region of the coil (41d). When an alternating current is applied to the coil (41d), the direction of the magnetic field formed inside the coil (41d) can be continuously changed. When the susceptor (152d) is positioned inside the coil (41d) and is exposed to an alternating magnetic field whose direction periodically changes, the susceptor (152d) can generate heat, and the cigarette accommodated in the susceptor (152d) can be heated. The shape of the coil (41d) may be a cylindrical shape wound along the longitudinal direction of the cigarette (2d), but is not limited thereto, and the coil (41d) may be implemented in various types, such as a flat coil.

[0308] The removable battery (12) can be separated from or mounted on the aerosol generator (1d), and when the aerosol generator (1d) is mounted with the removable battery (12), it can supply power to the coil (41d) for heating operation of the aerosol generator (15d), for example.

[0309] The control unit (13) can control the heating operation of the aerosol generator (15d) by controlling the power supplied to the coil (41d). For example, the control unit (13) can control the temperature at which the cigarette (2d) is heated by induction heating of the susceptor (152d) by adjusting the strength of the magnetic field induced by the coil (41d) according to the temperature profile.

[0310] FIG. 12e is a drawing for explaining an aerosol generating device (1e) having a replaceable cartridge (3) containing a liquid composition (2e) according to an exemplary embodiment.

[0311] The aerosol generating device (1e) of FIG. 12e includes a cartridge (3) containing a liquid composition (2e) and a main body (10) supporting the cartridge (3). The aerosol generating device (1e) may correspond to one type of the aerosol generating device (1). At this time, the hardware components included in the aerosol generating device (1) may be divided and positioned in the main body (10) and the cartridge (3).

[0312] The cartridge (3) can be coupled to the main body (10) while containing a liquid composition (2e) therein. The cartridge (3) can be mounted on the main body (10) by inserting a portion of the cartridge (3) into a receptacle of the main body (10).

[0313] The cartridge (3) may hold a liquid composition (2e) of a liquid composition, but is not limited thereto, and may also hold a liquid composition (2e) in any one of a solid state, a gaseous state, or a gel state. For example, the liquid composition may be a liquid containing a tobacco-containing substance including a volatile tobacco flavoring component, or may be a liquid containing a non-tobacco substance.

[0314] The aerosol generator (15e) provided in the cartridge (3) performs a heating operation by an electric signal or a wireless signal transmitted from the main body (10). Accordingly, the liquid composition (2e) inside the cartridge (3) can be vaporized by the heating of the aerosol generator (15e), thereby generating an aerosol.

[0315] The aerosol generator (15e) can be implemented with a conductive filament made of a metal material such as copper, nickel, or tungsten, or a ceramic heating element, etc., to heat an aerosol generating substance delivered to a liquid delivery means by generating heat by electrical resistance, and can be wound around the liquid delivery means or placed adjacent to the liquid delivery means.

[0316] The removable battery (12) can be separated from or mounted on the aerosol generator (1e), and when the aerosol generator (1e) is mounted with the removable battery (12), power can be supplied to the aerosol generator (15e) from the removable battery (12) for the heating operation of the aerosol generator (15e).

[0317] The control unit (13) can control the heating operation of the aerosol generator (15e) by controlling the power supplied to the aerosol generator (15e). For example, the control unit (13) can control the temperature at which the liquid composition (2e) is heated by the aerosol generator (15e) according to a temperature profile.

[0318] Meanwhile, although not illustrated in FIGS. 12a to 12e, the aerosol generating devices (1a to 1e) may also be configured as a system together with a separate cradle. For example, the cradle may store the aerosol generating devices (1a to 1e) or charge the removable battery (12) of the aerosol generating devices (1a to 1e).

[0319] According to various embodiments, the aerosol generating device (1) of FIG. 11 may be implemented as at least one of the types of aerosol generating devices (1a to 1e) of FIGS. 12a to 12e, but is not necessarily limited thereto and may be implemented as other types as well.

[0320] The aerosol generating devices (1a to 1e) of FIGS. 12a to 12e can commonly use a removable battery (12) as a power source. The removable battery (12) is a battery that can be replaced by being mounted or removed from the aerosol generating devices (1a to 1e).

[0321] However, since the electrodes in electrical contact with the removable battery (12) are exposed to the outside, water may penetrate the electrodes when the removable battery (12) is replaced. If water penetrates the electrodes, an overcurrent may occur due to a short circuit, which may cause a failure of the internal components of the aerosol generating device (1). In order to prevent such device failure, the present disclosure provides an aerosol generating device (1) that detects water penetrating the electrodes in electrical contact with the removable battery (12), notifies the user, and forcibly detaches the removable battery (12).

[0322] FIG. 13 is an exploded perspective view of some components of an aerosol generating device for explaining a method of coupling and disengaging a removable battery according to one embodiment.

[0323] Although only a part of the configuration of the aerosol generating device (1) is illustrated in FIG. 13, the components of the aerosol generating device (1) are not limited to the configurations illustrated in the drawing.

[0324] Referring to FIG. 13, an aerosol generating device (1) according to one embodiment may include a main body (10), a removable battery (12), and a magnetic coupling structure (162). The aerosol generating device (1) may be an embodiment of the aerosol generating device (1) of FIG. 11 and FIG. 12a to FIG. 12b, and any redundant description thereof will be omitted below.

[0325] The main body (10) can form the overall appearance of the aerosol generating device (1), and components of the aerosol generating device (1) can be arranged in the main body (10).

[0326] According to one embodiment, the main body (10) may include a battery coupling portion (16) for accommodating a removable battery (12). The battery coupling portion (16) may be referred to as a battery receiving space in that it includes a space for accommodating a battery. For example, the battery coupling portion (16) may be formed in an area of ​​the main body (10) (e.g., an area facing the x direction) to accommodate the removable battery (12), but the location of the battery coupling portion (16) is not limited thereto.

[0327] A body electrode (161) may be placed in the battery coupling portion (16), and the body electrode (161) may come into contact with the battery electrode (121) of the removable battery (12) when the removable battery (12) is coupled or accommodated in the battery coupling portion (16).

[0328] The body electrode (161) may include a first connection terminal (161a) and a second connection terminal (161b) that are in electrical contact with the battery electrode (121). In addition, the battery electrode (121) may include a first battery electrode (121a) that is in electrical contact with the first connection terminal (161a) and a second battery electrode (121b) that is in electrical contact with the second connection terminal (161b). The first battery electrode (121a) may function as a positive electrode, and the second battery electrode (121b) may function as a negative electrode.

[0329] Meanwhile, in FIG. 13, only an embodiment in which a first connection terminal (161a) is arranged on one side of the battery coupling portion (16) and a second connection terminal (161b) is arranged on the other side is illustrated, but the arrangement structure and number of the first connection terminal (161a) and the second connection terminal (161b) may be changed depending on the design of the battery electrode (121) of the removable battery (12).

[0330] The aerosol generating device (1) may further include a battery cover (17) that is detachably coupled to the main body (10) to protect the detachable battery (12). The battery cover (17) is detachably coupled to the main body (10) and can open or close the battery connection portion (16).

[0331] In one example, when the battery cover (17) is detached from the main body (10), the battery coupling portion (16) is exposed to the outside of the aerosol generating device (1), so that the detachable battery (12) can be coupled to the battery coupling portion (16). In another example, when the battery cover (17) is coupled to the main body (10), the battery cover (17) can protect the detachable battery (12) from external impact or the inflow of external foreign substances by preventing the battery coupling portion (16) from being exposed to the outside by being covered by the battery cover (17).

[0332] The removable battery (12) can be detachably connected to the battery coupling portion (16) of the main body (10) and can supply power for the operation of components of the aerosol generating device (1). For example, when the removable battery (12) is connected to the battery coupling portion (16), the battery electrode (121) of the removable battery (12) can come into contact with the main body electrode (161), thereby electrically connecting the removable battery (12) and the components of the aerosol generating device (1). The removable battery (12) can supply power to the electrically connected components of the aerosol generating device (1) to operate the components of the aerosol generating device (1).

[0333] The magnetic coupling structure (162) may be arranged in one area of ​​the battery coupling portion (16) and the main body (10), and may be magnetically coupled to the removable battery (12) to fix the removable battery (12) to the battery coupling portion (16). To this end, the magnetic coupling structure (162) may include a first electromagnet (162a) and a second electromagnet (162b). For example, the first electromagnet (162a) and the second electromagnet (162b) may be arranged in one area of ​​the main body (10) spaced apart from the battery coupling portion (16) in the z direction, and may be magnetically coupled to or decoupled from the removable battery (12) under the control of the control portion (13). The magnetic coupling structure (162) may be a configuration included in the disconnection portion (80) of FIG. 15 in that it is a configuration for coupling and decoupled from the removable battery (12).

[0334] The removable battery (12) may include a magnetic coupling structure (162) and a conductor (not shown) that is coupled by magnetic force. The conductor may be disposed inside or outside the removable battery (12). The removable battery (12) may include a first conductor (122a) and a second conductor (122b). The first conductor (122a) may be disposed at a position corresponding to the first electromagnet (162a) of the removable battery (12), and the second conductor (122b) may be disposed at a position corresponding to the second electromagnet (162b) of the removable battery (12).

[0335] Depending on the power supplied to the magnetic coupling structure (162), the first electromagnet (162a) and the second electromagnet (162b) can be magnetically coupled to or decoupled from the first conductor (122a) and the second conductor (122b), respectively. In one embodiment, the first electromagnet (162a) and the second electromagnet (162b) generate magnetic force under the control of the control unit (13), and the first conductor (122a) and the second conductor (122b) can be magnetically coupled to the first electromagnet (162a) and the second electromagnet (162b), respectively, by the generated magnetic force. In addition, the magnetic force of the first electromagnet (162a) and the second electromagnet (162b) is extinguished under the control of the control unit (13), and the first conductor (122a) and the second conductor (122b) can be released from the first electromagnet (162a) and the second electromagnet (162b) by the extinguished magnetic force.

[0336] The aerosol generating device (1) of the present disclosure can prevent the detachable battery (12) from being unintentionally detached from the battery coupling portion (16) by stably fixing the detachable battery (12) to the battery coupling portion (16) via the magnetic coupling structure (162). In addition, when water intrudes into the main body electrode (161), the detachable battery (12) is forcibly detached via the magnetic coupling structure (162), thereby preventing device failure.

[0337] FIG. 14 is a cross-sectional view of some components of an aerosol generating device for explaining a method of combining and separating a removable battery according to one embodiment.

[0338] Referring to Fig. 14, the first electromagnet (162a) and the second electromagnet (162b) may be arranged inside or outside one side of the battery coupling portion (16). The first electromagnet (162a) and the second electromagnet (162b) may be spaced apart from each other by a preset distance. For example, the first electromagnet (162a) and the second electromagnet (162b) may be spaced apart from each other in the z direction. Since the first electromagnet (162a) and the second electromagnet (162b) are spaced apart from each other, the magnetic force may not be concentrated in one place. Therefore, when the first electromagnet (162a) and the second electromagnet (162b) generate a magnetic force, the coupling between the removable battery (12) and the battery coupling portion (16) may be made more secure.

[0339] The first conductor (122a) and the second conductor (122b) may be placed inside or outside one side of the removable battery (12). The first conductor (122a) and the second conductor (122b) may be placed at positions corresponding to the first electromagnet (162a) and the second electromagnet (162b).

[0340] The first electromagnet (162a) and the second electromagnet (162b) can generate or extinguish magnetic force according to the control of the control unit (13). The control unit (13) can apply or recover magnetic force to each of the first electromagnet (162a) and the second electromagnet (162b) using the power of the internal battery (19). For this purpose, the aerosol generating device (1) may further include a DC / DC converter and a DC / AC converter. For example, the control unit (13) can control the output of the internal battery (19) to apply or recover magnetic force to each of the first electromagnet (162a) and the second electromagnet (162b).

[0341] The control unit (13) can supply power to the first electromagnet (162a) and the second electromagnet (162b) when water does not penetrate the main body electrode (161). Accordingly, each of the first electromagnet (162a) and the second electromagnet (162b) can generate magnetic force.

[0342] When water enters the main body electrode (161), the control unit (13) may not supply power to at least one of the first electromagnet (162a) and the second electromagnet (162b). In one embodiment, when water enters the main body electrode (161), the control unit (13) may cut off the power supplied to the first electromagnet (162a). When the power supplied to the first electromagnet (162a) is cut off, the connection between the removable battery (12) and the battery coupling unit (16) is performed only by the magnetic force between the second electromagnet (162b) and the second conductor (122b), so that the removable battery (12) can be easily separated from the battery coupling unit (16) by an external impact. In another embodiment, the control unit (13) may cut off the power supplied to both the first electromagnet (162a) and the second electromagnet (162b) when water intrudes into the main body electrode (161). As the control unit (13) cuts off the power supplied to both the first electromagnet (162a) and the second electromagnet (162b), the removable battery (12) may be forcibly detached from the battery coupling unit (16). Accordingly, device failure due to water intrusion can be more completely prevented.

[0343] Fig. 15 is an internal block diagram of an aerosol generating device according to one embodiment.

[0344] Referring to FIG. 15, the aerosol generating device (1) may include a removable battery (110), an aerosol generator (15), a control unit (13), an input unit (70), an output unit (40), a memory (60), an internal battery (19), a communication unit (50), a sensor unit (14), a water detection unit (90), and a disconnection unit (80). However, the hardware components inside the aerosol generating device (1) are not limited to those illustrated in FIG. 15. Those skilled in the art related to the present embodiment will understand that, depending on the design of the aerosol generating device (1), some of the hardware components illustrated in FIG. 15 may be omitted or new components may be added.

[0345] The removable battery (12) supplies power used to operate the aerosol generator (1). For example, the removable battery (12) may supply power so that the aerosol generator (15) may be heated. In addition, the removable battery (12) may supply power required for the operation of other hardware components provided in the aerosol generator (1), namely, the aerosol generator (15), the control unit (13), the input unit (70), the output unit (40), the memory (60), the communication unit (50), the sensor unit (14), and the water detection unit (90). In some embodiments, the removable battery (12) may also supply power required for the operation of the disconnection unit (80).

[0346] The removable battery (12) may be, for example, a lithium polymer (LiPoly) battery or a lithium ion battery, but is not limited thereto.

[0347] The removable battery (12) is a replaceable type (separate) power source, and can be mounted on or removed from the battery coupling portion (16) provided in the aerosol generating device (1). The removable battery (12) is provided with a battery electrode (121), and when the removable battery (12) is mounted on the aerosol generating device (1), the battery electrode (121) of the removable battery (12) can be implemented to be electrically connected to a body electrode (161) provided on the aerosol generating device (1) to supply power to the aerosol generating device (1).

[0348] The removable battery (12) may be provided with a charger interface that can be connected to an external charger. Power for charging the removable battery (12) may be supplied to the removable battery (12) through the charger interface. The removable battery (12) may be charged by an external charger while connected to the aerosol generating device (1) or while being removed (uninstalled) from the aerosol generating device (1).

[0349] The removable battery (12) may optionally be equipped with an NFC tag. The NFC tag equipped on the removable battery (12) can be read through a protocol for short-range communication with an NFC module. The NFC tag of the removable battery (12) may include a recording medium on which identification information related to the removable battery (12), battery capacity information, etc. are recorded. Accordingly, the aerosol generating device (1) can obtain various information, such as whether the removable battery (12) is an authenticated product or the battery capacity, based on the information received from the NFC tag of the removable battery (12).

[0350] The aerosol generator (15) receives power from a removable battery (12) under the control of the control unit (13). The aerosol generator (15) can heat a cigarette inserted into the aerosol generator (1) or a cartridge mounted on the aerosol generator (1) using the power supplied from the removable battery (12). That is, the aerosol generator (15) can generate an aerosol by heating an aerosol generating material provided in the cigarette or cartridge.

[0351] The aerosol generator (15) may be located in the body of the aerosol generator (1). Alternatively, if the aerosol generator (1) is composed of a body and a cartridge, the aerosol generator (15) may be located in the cartridge. If the aerosol generator (15) is located in the cartridge, the aerosol generator (15) may be powered by a removable battery (12) located in the body.

[0352] The aerosol generator (15) can be implemented as an electric resistance heater or an induction heating heater, and a description thereof is given in FIGS. 12a to 12e.

[0353] The input unit (70) can receive user input. For example, the input unit (70) can be implemented as a single pressurized push button. As another example, the input unit (70) can be a touch panel including at least one touch sensor. The input unit (70) can transmit an input signal to the control unit (13). The control unit (13) can supply power to the aerosol generator (15) based on the user input or control the output unit (40) to output a user notification.

[0354] The output unit (40) can output information about the status of the aerosol generating device (1). The output unit (40) can output the charge / discharge status of the removable battery (12) and / or the internal battery (19), the heating status of the aerosol generator (15), the insertion status of the aerosol generating article (2), and error information of the aerosol generating device (1). For this purpose, the output unit (40) can include a display, a haptic motor, and an audio output unit.

[0355] The sensor unit (14) can detect the status of the aerosol generating device (1) or the surrounding status of the aerosol generating device (1) and transmit the detected information to the control unit (13). For this purpose, the sensor unit (14) may include a temperature sensor, a puff sensor, and an insertion detection sensor. However, the sensors included in the sensor unit (14) are not limited to the examples described above, and additional sensors may be included according to embodiments. For example, the sensor unit (14) may additionally include a reuse detection sensor, a motion detection sensor, a humidity sensor, a barometric pressure sensor, a magnetic sensor, a cover removal detection sensor, a location sensor (GPS), a proximity sensor, and the like. If the function of each sensor is included in the name of each sensor, a specific description of the function of each sensor is omitted.

[0356] The control unit (13) can control the aerosol generating device (1) to perform various functions, such as heating control of the aerosol generator (15), smoking restriction, determining whether an aerosol generating article (2) is inserted, and displaying a notification, based on the detected information.

[0357] The communication unit (50) may include at least one communication module for communicating with an external electronic device. The control unit (13) may control the communication unit (50) to transmit information about the aerosol generating device (1) to the external electronic device. Alternatively, the control unit (13) may receive information from the external electronic device through the communication unit (50) and control components included in the aerosol generating device (1). For example, information transmitted between the communication unit (50) and the external electronic device may include user authentication information, firmware update information, and user smoking pattern information.

[0358] The memory (60) is hardware that stores various data processed within the aerosol generating device (1), and can store data processed and data to be processed in the control unit (13). For example, the memory (60) can store data on the operation time of the aerosol generating device (1), the maximum number of puffs, the current number of puffs, at least one temperature profile, and the user's smoking pattern.

[0359] The internal battery (19) has a configuration distinct from the removable battery (12) and can be fixed inside the aerosol generating device (1). Unlike the removable battery (12), the internal battery (19) is not detachable and can supply a minimum amount of power to the internal components of the aerosol generating device (1). The capacity of the internal battery (19) may be smaller than the capacity of the removable battery (12). In addition, the output power of the internal battery (19) may be set to be smaller than the output power of the removable battery (12).

[0360] The internal battery (19) can supply power to the internal components of the aerosol generator (1) even when the removable battery (12) is not mounted on the aerosol generator (1). For example, the internal battery (19) can supply power greater than the standby power to the control unit (13) at the request of the control unit (13). In addition, the internal battery (19) can secure the removable battery (12) to the aerosol generator (1) or separate the removable battery (12) from the aerosol generator (1) by supplying power to the disconnecting unit (80). However, unlike the removable battery (12), the power output from the internal battery (19) is not used for heating the aerosol generator (15).

[0361] The power output from the internal battery (19) can be used when the removable battery (12) is not installed. For example, the power output from the internal battery (19) can be provided to the input unit (70), the output unit (40), the memory (60), the communication unit (50), and the sensor unit (14) when the removable battery (12) is not installed. According to an embodiment, the power output from the internal battery (19) can be used even when the removable battery (12) is installed. For example, the power output from the internal battery (19) can be provided to the water detection unit (90) and the disconnection unit (80) when the removable battery (12) is installed. However, regardless of whether the removable battery (12) is installed, the power may not be provided to the aerosol generator (15).

[0362] The internal battery (19) can be charged by the removable battery (12). For example, the internal battery (19) can be charged while the aerosol generator (15) is not heating.

[0363] The main body electrode (161) is composed of a conductor and can make electrical contact with the removable battery (12). The main body electrode (161) can transmit the output power of the removable battery (12) to the internal components of the aerosol generating device (1). For this purpose, the main body electrode (161) can include a first connection terminal (161a) and a second connection terminal (161b).

[0364] The water detection unit (90) can detect water entering the main body electrode (161). The water detection unit (90) is positioned adjacent to the main body electrode (161), detects water entering the main body electrode (161), and outputs a detection signal as a detection result. The 'water' detected by the water detection unit (90) can also be called 'liquid'. In addition, 'water' can mean pure water, liquid or moisture containing various substances.

[0365] The water detection unit (90) can be connected to the main body electrode (161). The water detection unit (90) can be connected to at least one of the first connection terminal (161a) and the second connection terminal (161b).

[0366] The water detection unit (90) can be powered by a removable battery (12). Depending on the embodiment, the water detection unit (90) can also be powered by an internal battery (19).

[0367] The water detection unit (90) can transmit a detection signal to the control unit (13) when water penetrates the main body electrode (161). When the control unit (13) receives a detection signal from the water detection unit (90), it can cut off the power supplied to the aerosol generator (15) even if a user input is received. When the water detection unit (90) does not receive a detection signal from the water detection unit (90), it can control the operation of a typical aerosol generation device (1). For example, the water detection unit (90) can heat the aerosol generator (15) according to a user input and control the temperature of the aerosol generator (15) according to a temperature profile. A detailed description of the water detection unit (90) will be described later with reference to FIG. 16 and below.

[0368] The control unit (13) is hardware that controls the overall operation of the aerosol generating device (1). The control unit (13) may include at least one processing unit, such as an MCU (Micro Controller Unit). The control unit (13) may be implemented as an array of multiple logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory storing a program that can be executed on the microprocessor. In addition, the control unit (13) may be implemented as other types of hardware.

[0369] The control unit (13) can be powered by the internal battery (19) when the removable battery (12) is not installed or when water penetrates the main body electrode (161) and the removable battery (12) is forcibly separated from the aerosol generating device (1). The control unit (13) can update time information using the internal battery (19) or control the output unit (40) to output information according to user input. For example, the control unit (13) can control the output unit (40) to output time information, insertion information of the removable battery (12), smoking information, etc.

[0370] The control unit (13) can control the power output from the removable battery (12) to heat the aerosol generator (15) when the removable battery (12) is normally inserted. For example, the control unit (13) can control the amount and supply time of the power output from the removable battery (12) so that the aerosol generator (15) is heated according to a preset temperature profile. In addition, the control unit (13) can sense the user's puff using the puff sensor in the sensor unit (14) and then control the temperature of the aerosol generator (15). In addition, the control unit (13) can count the number of puffs using the puff sensor and then stop supplying power to the aerosol generator (15) when the number of puffs reaches a preset number. The control unit (13) can also control the output unit (40) based on the sensing result. For example, when the number of puffs is counted using a puff sensor and the number of puffs reaches a preset number, the control unit (13) can use a lamp, motor, or speaker to notify the user that the aerosol generating device (1) will soon be terminated.

[0371] Fig. 16 is a circuit diagram of a water detection unit according to one embodiment.

[0372] Referring to FIG. 16, the removable battery (12) has an internal resistance (Rs) and can be in detachable contact with the first connection terminal (161a) and the second connection terminal (161b). For example, the positive electrode of the removable battery (12) can be in electrical contact with the first connection terminal (161a), and the negative electrode of the removable battery (12) can be in electrical contact with the second connection terminal (161b). When the removable battery (12) is in electrical contact with the connection terminals (161a, 161b) in a designated direction, it can provide power to the internal components of the aerosol generating device (1).

[0373] Meanwhile, when water intrudes into the connection terminals (161a, 161b) while the removable battery (12) is in electrical contact with the connection terminals (161a, 161b) in a designated direction, the connection terminals (161a, 161b) may be momentarily connected to the ground terminal through the low-resistance water, thereby generating a high current or voltage. This high current or voltage affects the durability of the internal components of the aerosol generating device (1), and therefore, a method is needed to detect water intrusion into these connection terminals (161a, 161b) and protect the aerosol generating device (1).

[0374] The present disclosure may include a water detection unit (90) that detects water intruding into a main body electrode (161) and outputs a detection signal as a detection result. To this end, the water detection unit (90) may include a detection element unit (91) and a signal generation unit (92).

[0375] The water detection unit (90) can be connected to at least one of the first connection terminal (161a) and the second connection terminal (161b). FIG. 16 illustrates an embodiment in which the water detection unit (90) is connected to the first connection terminal (161a), but depending on the embodiment, the water detection unit (90) can be connected to the second connection terminal (161b) or to each of the first connection terminal (161a) and the second connection terminal (161b).

[0376] The sensing element unit (91) can be driven by a removable battery (12) or an internal battery (19), and is composed of elements that detect water entering the main body electrode (161). The sensing element unit (91) can include a sensing electrode (TS), at least one resistance element (R), a first switching element (SW1), and a second switching element (SW2).

[0377] The sensing electrode (TS) is composed of a conductor and can detect a sensing voltage generated by water entering the main body electrode (161). The sensing voltage may refer to a momentary high voltage generated by water entering the main body electrode (161).

[0378] The sensing electrode (TS) may be arranged adjacent to at least one of the first connection terminal (161a) and the second connection terminal (161b). The sensing electrode (TS) may be arranged adjacent to the connection terminal to which the water detection unit (90) is connected. For example, when the water detection unit (90) is connected to the first connection terminal (161a), the sensing electrode (TS) may be arranged adjacent to the first connection terminal (161a) arranged on one surface of the battery coupling unit (16) and may be exposed to the outside. Hereinafter, a case in which the sensing electrode (TS) is arranged adjacent to the first connection terminal (161a) will be described.

[0379] The detection voltage can be generated between the first connection terminal (161a) and the detection electrode (TS) by water that has penetrated the main body electrode (161).

[0380] The resistance element (R) is connected to the sensing electrode (TS) and can step down the sensing voltage. The resistance element (R) can step down the sensing voltage to protect the internal components of the circuit. In addition, the resistance element (R) can also be used to induce a reverse bias voltage or a forward bias voltage of the first switching element (SW1) described later. Although Fig. 16 only describes an embodiment in which the water sensing unit (90) includes one resistance element (R), depending on the embodiment, a plurality of resistance elements (R) may be provided.

[0381] The first switching element (SW1) may be connected to the resistive element (R1). In one embodiment, the first switching element (SW1) may be composed of a bipolar junction transistor (BJT) of an npn type. The first switching element (SW1) may include a first terminal connected to the resistive element (R), a second terminal connected to a ground terminal, and a third terminal in which a current path is created between the second terminal and the first terminal by a voltage input to the first terminal. When the first switching element (SW1) is of an npn type, the first terminal may be a base (B), the second terminal may be an emitter (E), and the third terminal may be a collector (C). In addition, when a pressured sensing voltage is applied to the base (B), a current path may be formed from the collector (C) to the emitter (E).

[0382] The second switching element (SW2) can be connected to the first switching element (SW1). The second switching element (SW2) is connected to the first switching element (SW1) and the first connection terminal (161a), and can electrically connect or disconnect the first connection terminal (161a) and the signal generation unit (92) according to the on / off of the first switching element (SW1). In one embodiment, the second switching element (SW2) can be configured as a relay switch.

[0383] When the second switching element (SW2) is configured as a relay switch, the second switching element may include a coil and a switch. The coil is connected to the third terminal of the first switching element (SW1), and when the first switching element (SW1) is turned on, the switch can be pulled in one direction to connect the first connection terminal (161a) and the signal generation unit (92).

[0384] The signal generating unit (92) is connected to the second switching element (SW2) and can generate a detection signal based on the detection result of the detection element unit (91). The signal generating unit (92) can transmit the detection signal to the control unit (13). The signal generating unit (92) can be driven using power from a removable battery (12) and / or an internal battery (19).

[0385] Fig. 17 is a drawing for explaining circuit operation according to the water detection result of the water detection unit of Fig. 16.

[0386] Referring to Fig. 17, when the removable battery (12) is in electrical contact with the connection terminals (161a, 161b) in a designated direction and water enters the connection terminals (161a, 161b), a high voltage can be instantaneously applied between the first connection terminal (161a) and the detection electrode (TS). The detection electrode (Ts) can detect the detection voltage (Vs) generated by the water entering the main body electrode (161).

[0387] The resistor element (R) can protect the internal components of the circuit by forcing the detection voltage (Vs). In addition, the resistor element (R) can be arranged for the bias voltage of the first switching element (SW1). The forcing detection voltage (Vs) is provided to the base (B) of the first switching element (SW1), and thus, a current path can be formed from the collector (C) to the emitter (E).

[0388] The power supplied to the first connection terminal (161a) can flow to the ground terminal (GND) through the current path provided by the first switching element (SW1), and accordingly, the coil of the second switching element (SW2) can pull the switch toward the coil, thereby electrically connecting the first connection terminal (161a) and the signal generation unit (92). In other words, the power of the first connection terminal (161a) can be supplied to the signal generation unit (92) through the first current path (path 1). In this way, the immersion detection circuit of the present disclosure can detect the intrusion of water into the main body electrode (161) by using the power of the removable battery (12) rather than the internal battery (19).

[0389] The signal generation unit (92) can generate a detection signal (S1) based on the detection result of the detection element unit (91) and transmit it to the control unit (13). In one embodiment, the signal generation unit (92) can output power provided from the first connection terminal (161a) as the detection signal (S1). In this case, the signal generation unit (92) can output the detection result using power from the removable battery (12) rather than the internal battery (19). In another embodiment, when the signal generation unit (92) receives power from the first connection terminal (161a), it can generate the detection signal (S1) using the internal battery (19) and transmit it to the control unit (13).

[0390] Fig. 18 is a drawing for explaining the operation method of the output unit according to the water detection result of the water detection unit of Fig. 16.

[0391] Referring to Fig. 18, when the control unit (13) receives a detection signal (S1) from the signal generation unit (92), it can cut off the power supplied to the aerosol generator (15) even when receiving a user input through the input unit (70). This is to more completely protect the internal components of the device by cutting off the power supplied to the aerosol generator (15), which consumes the most power among the internal components of the aerosol generation device (1).

[0392] The control unit (13) can output the water detection result through the output unit (40). For example, the control unit (13) can control the output unit (40) while cutting off the power supplied to the aerosol generator (15) to output text (41b), such as "water detection", along with a graphic object (41a) corresponding to the water detection result, through a predetermined display (41). At this time, the graphic object (41a) and the text (41b) can blink.

[0393] Meanwhile, the driving power of the output unit (40) of Fig. 18 can be supplied from the internal battery (19). This is to more completely protect the internal components of the device by minimizing the power supply to the internal components of the aerosol generating device (1) when submersion is detected.

[0394] FIG. 19a and FIG. 19b are drawings for explaining a method of combining and separating a detachable battery according to the water detection result of the water detection unit of FIG. 16.

[0395] Figures 19a and 19b illustrate the process in which the detachable battery (12) changes from a state of being connected to the battery joint (16) to a state of being forcibly separated when water penetrates the main body electrode (161).

[0396] Referring to FIGS. 19a and 19b, the control unit (13) can control the disconnection unit (80) to release the electrical contact between the removable battery (12) and the main body electrode (161). Meanwhile, FIGS. 19a and 19b are drawings for explaining the coupling and disengagement of the removable battery (12) according to the control signal of the control unit (13), and additional components such as an internal battery (19) and a power conversion unit (not shown) may be required between the removable battery (12) and the control unit (13).

[0397] The disconnecting portion (80) may include a magnetic coupling structure (162). The magnetic coupling structure (162) may include a first electromagnet (162a) positioned corresponding to a first conductor (122a) of the removable battery (12) and a second electromagnet (162b) positioned corresponding to a second conductor (122b) of the removable battery (12).

[0398] The control unit (13) can use the first magnetic signal (Sm1) to magnetically couple the removable battery (12) and the main body electrode (161). For example, the control unit (13) can move the removable battery (12) in the -x direction using the first magnetic signal (Sm1). In addition, the control unit (13) can release the magnetic coupling between the removable battery (12) and the main body electrode (161) using the second magnetic signal (Sm2). For example, the control unit (13) can move the removable battery (12) in the +x direction using the first magnetic signal (Sm1).

[0399] The control unit (13) can fix the removable battery (12) to the battery coupling unit (16) using the first magnetic signal (Sm1) regardless of whether water has intruded when the removable battery (12) is accommodated in the battery coupling unit (16). The control unit (13) can control at least one of the first electromagnet (162a) and the second electromagnet (162b) to generate magnetic force by controlling the output of the internal battery (19) using the first magnetic signal (Sm1). In one embodiment, the control unit (13) can control the first electromagnet (162a) and the second electromagnet (162b) to generate magnetic force using the first magnetic signal (Sm1) regardless of whether water has intruded when the removable battery (12) is accommodated in the battery coupling unit (16). In another embodiment, when the removable battery (12) is accommodated in the battery coupling portion (16), the control unit (13) can control only the first electromagnet (162a) to generate magnetic force using the first magnetic force signal (Sm1) regardless of whether water has intruded, and then control the second electromagnet (162b) to also generate magnetic force only when it is confirmed that no water has intruded.

[0400] When the control unit (13) receives a detection signal (S1) from the signal generation unit (220), it can determine that water has entered the main body electrode (161). In addition, when the control unit (13) determines that water has entered the main body electrode (161), it can release the magnetic coupling between the removable battery (12) and the main body electrode (161) using the second magnetic signal (Sm2). In other words, the control unit (13) can forcibly separate the removable battery (12) from the battery coupling unit (16) using the second magnetic signal (Sm2).

[0401] The control unit (13) can control both the first electromagnet (162a) and the second electromagnet (162b) to not generate magnetic force using the second magnetic force signal (Sm2). Accordingly, the detachable battery (12) can be separated from the battery coupling unit (16).

[0402] Meanwhile, the separation of the removable battery (12) of FIGS. 19a and 19b can be performed after notification of the submersion result through the output unit (40) of FIG. 18. In other words, the control unit (13) can notify the user of the submersion status through the output unit (40), and if the removable battery (12) is not separated from the battery coupling unit (16) even after a predetermined period of time has elapsed, the control unit (13) can forcibly separate the removable battery (12) from the battery coupling unit (16).

[0403] Figure 20 is a flowchart for explaining an operation method of an aerosol generating device according to one embodiment.

[0404] Referring to FIG. 20, at step S1010, the water detection unit (90) can detect water entering the body electrode (161) that is in electrical contact with the removable battery (12).

[0405] The water detection unit (90) may be connected to the main body electrode (161). The water detection unit (90) may be connected to at least one of the first connection terminal (161a) and the second connection terminal (161b). The water detection unit (90) may be powered by a removable battery (12). Depending on the embodiment, some components of the water detection unit (90) may also be powered by an internal battery (19).

[0406] The water detection unit (90) can transmit a detection signal (S1) to the control unit (13) when water enters the main body electrode (161).

[0407] At step S1020, the control unit (13) can determine whether water has entered the main body electrode (161) based on the detection signal (S1).

[0408] The detection signal (S1) may be generated from the signal generation unit (92) within the water detection unit (90). In one embodiment, the signal generation unit (92) may output power provided from the first connection terminal (161a) as the detection signal (S1). In this case, the signal generation unit (92) may output the detection result using power from the removable battery (12) rather than the internal battery (19). In another embodiment, when the signal generation unit (92) receives power from the first connection terminal (161a), it may generate the detection signal (S1) using the internal battery (19) and transmit it to the control unit (13).

[0409] At step S1030, when the control unit (13) receives a detection signal (S1) from the signal generation unit (92), it determines that water has entered the main body electrode (161) and can cut off the power supplied to the aerosol generator (15).

[0410] If the control unit (13) determines that water has entered the main body electrode (161), it can cut off the power supplied to the aerosol generator (15) even when receiving user input through the input unit (70).

[0411] At step S1040, if the control unit (13) determines that water has entered the main body electrode (161), it can output the water detection result through the output unit (40).

[0412] The control unit (13) can control the output unit (40) to output the water detection result while the power supplied to the aerosol generator (15) is cut off. For example, the output unit (40) can output a graphic object corresponding to the water detection result.

[0413] At step S1050, if the control unit (13) determines that water has entered the main body electrode (161), the detachable battery (12) can be separated from the battery coupling unit (16).

[0414] The control unit (13) can control the disconnection unit (80) to disconnect the removable battery (12) from the aerosol generator (1) while cutting off the power supplied to the aerosol generator (15). To this end, the disconnection unit (80) can include a magnetic coupling structure (162) in which magnetic force is generated or extinguished according to the control of the control unit (13).

[0415] The magnetic coupling structure (162) can fix the removable battery (12) to the aerosol generating device (1) by the generated magnetic force, or separate the removable battery (12) from the aerosol generating device (1) by the dissipated magnetic force.

[0416] The control unit (13) can forcibly separate the detachable battery (12) from the aerosol generating device (1) by controlling the disconnection unit (80) within a preset time from the end point of outputting the water detection result through the output unit (40). For example, the preset time may be 3 seconds, but is not limited thereto.

[0417] At step S1060, if the control unit (13) does not receive a detection signal (S1) from the signal generation unit (92), it determines that water has not penetrated the main body electrode (161) and can control the power supplied to the aerosol generator (15) according to user input.

[0418] The control unit (13) can receive user input through the input unit (70) and initiate heating of the aerosol generator (15) based on the user input when water does not penetrate the main body electrode (161). In addition, the aerosol generator (15) can be heated according to a preset temperature profile.

[0419] Any or all of the embodiments of the present disclosure described above are not mutually exclusive or distinct. Any or all of the embodiments of the present disclosure described above may have their respective components or functions combined or used together.

[0420] For example, it means that a configuration A described in a particular embodiment and / or drawing can be combined with a configuration B described in another embodiment and / or drawing. That is, even if a combination between configurations is not directly described, it means that a combination is possible, except in cases where a combination is described as impossible.
