[0099] For example, referring to FIG. 7, the battery (12) can be coupled to the battery coupling portion (16) such that the first surface (12a) faces the +y direction, the first battery electrode (121a) can be electrically connected to the main body electrode (161), and power of the battery (12) can be supplied to the main body electrode (161) through the first battery electrode (121a).

[0100] As another example, unlike that shown in FIG. 7, the battery (12) can be coupled to the battery coupling portion (16) such that the second side (12b) faces the +y direction, the second battery electrode (121b) can be electrically connected to the main body electrode (161), and power of the battery (12) can be supplied to the main body electrode (161) through the second battery electrode (121b).

[0101] Therefore, the coupling direction of the battery (12) capable of supplying power to the main body electrode (161) is not limited to the coupling direction illustrated in Fig. 7. Even if the battery (12) is coupled to the battery coupling portion (16) in a state in which the direction illustrated in Fig. 7 is upside down, it can supply power to the main body electrode (161), and the aerosol generating device (1) can operate without any problem.

[0102] According to the present disclosure, the user can operate the aerosol generating device (1) by connecting the battery (12) to the battery connecting portion (16) without paying attention to the connecting direction of the battery (12), thereby improving user convenience and user experience.

[0103] The aerosol generating device (1) may include a battery cover (17) that can selectively open or close the battery coupling portion (16). The battery cover (17) may be detachably coupled to the main body (10).

[0104] Referring to Fig. 7, 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.

[0105] The battery cover (17) can be placed in one area of ​​the main body (10). The battery cover (17) can be placed in an area corresponding to the battery coupling portion (16). For example, the battery cover (17) can be detachably coupled to the battery coupling portion (16) in a position where it is open in the -y direction.

[0106] Referring to Fig. 7, the battery cover (17) can extend in a direction transverse to the longitudinal direction (±y) of the main body (10). The battery cover (17) can open or close the battery connection portion (16) toward the longitudinal direction of the main body (10).

[0107] 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.

[0108] 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.

[0109] 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).

[0110] 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 (12) can be coupled to the battery coupling portion (16) or the battery (12) can be removed from the battery coupling portion (16).

[0111] The aerosol generating device (1) may further include an elastic body (162). The elastic body (162) may be connected to the main body electrode (161). The elastic body (162) may apply elastic force to the main body electrode (161) to pressurize the main body electrode (161). The elastic body (162) may press the main body electrode (161) toward the battery (12). By the elastic body (162), the main body electrode (161) may be more stably brought into contact with and / or coupled to the battery electrode (121) of the battery (12). By the elastic body (162), the main body electrode (161) may be more stably electrically connected to the battery electrode (121) of the battery (12).

[0112] The body electrode (161) may include a pogo pin pressed by an elastic body (162) or may be the pogo pin itself.

[0113] The elastic body (162) can stably fix the battery (12) without shaking within the battery coupling portion (16). The size of the battery (12) coupled to the battery coupling portion (16) may vary depending on the battery (12). By arranging the elastic body (162), the battery (12) can be stably placed in the battery coupling portion (16) regardless of the size of the battery (12). By arranging the elastic body (162), the degree of freedom in the size of the battery (12) that can be coupled to the battery coupling portion (16) can be improved.

[0114] The elastic body (162) can pressurize the battery coupled to the battery coupling portion (16). The elastic body (162) can be placed inside the battery coupling portion (16). One or more elastic bodies (162) can be placed.

[0115] A cover electrode (171) and a charging terminal (172) can be placed on the battery cover (17).

[0116] The cover electrode (171) may be configured to electrically connect the charging terminal (172) and the battery electrode (121). The cover electrode (171) may be selectively electrically connected to either the first battery electrode (121a) or the second battery electrode (121b). The cover electrode (171) may connect either the first battery electrode (121a) or the second battery electrode (121b) and the charging terminal (172).

[0117] The charging terminal (172) is configured to charge the battery (12) by supplying power to the battery (12) from an external charger (not shown). The cover electrode (171) can supply power to the battery (12) through the first battery electrode (121a) or the second battery electrode (121b).

[0118] According to the present disclosure, the cover electrode (171) can supply power to the battery (12) only by electrical connection with either the first battery electrode (121a) or the second battery electrode (121b), so that the degree of freedom in the coupling direction of the battery (12) coupled to the battery coupling portion (16) can be improved.

[0119] According to the present disclosure, even if the battery (12) is coupled to the battery coupling portion (16) in a direction different from that shown in FIG. 1, the cover electrode (171) can supply power to the battery (12).

[0120] For example, when the first side (12a) of the battery (12) is connected to the battery coupling portion (16) so that it faces the +y direction, the second battery electrode (121b) can be electrically connected to the cover electrode (171), and power can be supplied to the battery (12) through the second battery electrode (121b).

[0121] As another example, when the second side (12b) of the battery (12) is coupled to the battery coupling portion (16) so that it faces the +y direction, the first battery electrode (121a) can be electrically connected to the cover electrode (171), and power can be supplied to the battery (12) through the first battery electrode (121a).

[0122] Therefore, the direction of coupling of the battery (12) capable of charging the battery (12) is not limited to the direction of coupling illustrated in Fig. 1. The battery (12) can receive power from the cover electrode (171) even when coupled to the battery coupling portion (16) in a state in which the battery (12) is turned upside down in the direction illustrated in Fig. 1.

[0123] According to the present disclosure, the user can operate the aerosol generating device (1) by connecting the battery (12) to the battery connecting portion (16) without paying attention to the connecting direction of the battery (12), thereby improving user convenience and user experience.

[0124] The aerosol generating device (1) may further include a cradle (not shown). The aerosol generating device (1) may be configured as a system together with a separate cradle. The cradle may include a charger capable of charging the battery (12). For example, the cradle may charge the battery (12) of the aerosol generating device (1). Alternatively, the aerosol generator (15) may be heated while the cradle and the aerosol generating device (1) are combined.

[0125] FIG. 8 is a drawing for explaining in detail the battery (12) and battery coupling part (16) of an aerosol generating device according to one embodiment of the present disclosure.

[0126] The battery (12) and battery coupling part (16) of FIG. 8 may have the same or similar configuration as the battery (12) and battery coupling part (16) of the embodiment described above with reference to FIG. 7.

[0127] For convenience of explanation, the illustration of components other than the battery (12) and the battery coupling portion (16) is omitted in Fig. 8.

[0128] The battery (12) may include a curved surface. For example, the battery (12) may have a cylindrical shape, but the shape of the battery (12) is not limited thereto.

[0129] When the battery (12) is cylindrical, the first surface (12a) and the second surface (12b) may be the bottom surfaces of the cylinders forming the shape of the battery. The first surface (12a) and the second surface (12b) may face in opposite directions. The first surface (12a) and the second surface (12b) of the battery (12) may face each other.

[0130] According to one embodiment of the present disclosure, at least a portion of the inner surface of the battery coupling portion (16) may be curved, but is not limited thereto.

[0131] A body electrode (161) may be placed in an area inside the battery coupling portion (16). The body electrode (161) is configured to be electrically connected to the battery (12). The 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 (not shown), the sensor (not shown), and the aerosol generator (not shown) may receive current from the battery (12) through the body electrode (161).

[0132] The main body electrode (161) can be electrically connected to at least one of the battery electrodes (121) of the battery (12) coupled to the battery coupling portion (16). For example, the main body electrode (161) can be selectively electrically connected to either the first battery electrode (121a) or the second battery electrode (121b). The main body electrode (161) can receive power from either the first battery electrode (121a) or the second battery electrode (121b).

[0133] According to the present disclosure, the main body electrode (161) can receive power from the battery (12) only by electrical connection with either the first battery electrode (121a) or the second battery electrode (121b), so the degree of freedom in the coupling direction of the battery (12) coupled to the battery coupling portion (16) can be improved.

[0134] According to the present disclosure, even if the battery (12) is connected to the battery coupling portion (16) in a direction different from that shown in FIG. 1, the main body electrode (161) can receive power from the battery (12).

[0135] For example, referring to FIG. 8, the battery (12) can be coupled to the battery coupling portion (16) such that the first surface (12a) faces the +y direction, the first battery electrode (121a) can be electrically connected to the main body electrode (161), and power of the battery (12) can be supplied to the main body electrode (161) through the first battery electrode (121a).

[0136] As another example, unlike that shown in FIG. 8, the battery (12) can be coupled to the battery coupling portion (16) such that the second side (12b) faces the +y direction, the second battery electrode (121b) can be electrically connected to the main body electrode (161), and power of the battery (12) can be supplied to the main body electrode (161) through the second battery electrode (121b).

[0137] Therefore, the coupling direction of the battery (12) capable of supplying power to the main body electrode (161) is not limited to the coupling direction illustrated in Fig. 8. Even if the battery (12) is coupled to the battery coupling portion (16) in a state in which the battery is upside down in the direction illustrated in Fig. 8, it can supply power to the main body electrode (161), and the aerosol generating device (1) can operate without any problem.

[0138] According to the present disclosure, the user can operate the aerosol generating device (1) by connecting the battery (12) to the battery connecting portion (16) without paying attention to the connecting direction of the battery (12), thereby improving user convenience and user experience.

[0139] The shape of the battery electrode (121) and the shape of the body electrode (161) may be shapes that correspond to each other so that they can be electrically connected. The body electrode (161) may be circular. The body electrode (161) may include a positive circular electrode and a negative circular electrode. The battery electrode (121) may be circular in shape corresponding to the body electrode (161). The battery electrode (121) may include a positive circular electrode and a negative circular electrode.

[0140] According to an embodiment described with reference to FIG. 8, when the battery (12) is in a cylindrical shape, the battery electrode (121) and the body electrode (161) are formed in a circular shape, so that the degree of freedom in the coupling direction of the battery (12) can be further improved. The battery (12) can be coupled to the battery coupling portion (16) regardless of the up-down (±y) direction as well as the left-right (±x) direction to operate the aerosol generating device (1).

[0141] FIG. 9a and FIG. 9b are drawings for explaining an aerosol generating device according to one embodiment of the present disclosure.

[0142] 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 other drawings, but is not limited thereto.

[0143] FIG. 9a and FIG. 9b are schematic cross-sectional views for explaining in detail the configurations related to the battery (12), battery coupling portion (16), and battery cover (17) of the aerosol generating device (1).

[0144] To avoid repetitive description, description of a configuration identical or similar to that of an aerosol generating device (1) of any of the embodiments described with reference to other drawings may be omitted.

[0145] Referring to FIGS. 9A and 9B, the battery (12) can be coupled to 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).

[0146] 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.

[0147] 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).

[0148] Referring to FIGS. 9a and 9b, the battery (12) is placed inside the battery coupling portion (16), the battery cover (17) is in a closed position, and the battery cover (17) closes the battery coupling portion (16) so that the battery (12) is not discharged to the outside.

[0149] The extension direction of the battery cover (17) of the aerosol generating device (1) is not limited.

[0150] For example, referring to FIG. 9A, the battery cover (17) may extend in a direction that is the same as or similar to the longitudinal direction (±y) of the main body (10). The battery cover (17) may open or close the battery coupling portion (16) in a direction that crosses the longitudinal direction of the main body (10). In this case, the battery coupling portion (16) may be opened in a direction that crosses the longitudinal direction of the main body (10) when opened by the battery cover (17).

[0151] As another example, referring to FIG. 9b, the battery cover (17) may extend in a direction transverse to the longitudinal direction (±y) of the main body (10). The battery cover (17) may open or close the battery coupling portion (16) toward the longitudinal direction of the main body (10). In this case, the battery coupling portion (16), when opened by the battery cover (17), may open in a direction identical to or similar to the longitudinal direction of the main body (10).

[0152] A body electrode (161) may be placed in an area inside the battery joint (16). The body electrode (161) is configured to be electrically connected to the battery (12). The body electrode (161) may receive current from the battery (12) and transmit the current to other components of the aerosol generating device (1).

[0153] 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 a body electrode (161). The battery electrode (121) may supply current to other components of the aerosol generating device (1) through the body electrode (161). The battery (12) may include a plurality of battery electrodes (121). For example, the battery (12) may include a first battery electrode (121a) and a second battery electrode (121b). The battery (12) may include a greater number of electrodes in addition to the first battery electrode (121a) and the second battery electrode (121b), and the number of battery electrodes (121) included in the battery (12) is not limited.

[0154] The battery (12) may have multiple surfaces. Among the surfaces of the battery (12), the first surface (12a) and the second surface (12b) may be inclined surfaces that form a predetermined angle with the longitudinal direction of the battery (12). The first battery electrode (121a) disposed on the first surface (12a) may be disposed inclined like the first surface (12a), and the second battery electrode (121b) disposed on the second surface (12b) may be disposed inclined like the second surface (12b).

[0155] The aerosol generating device (1) may include a main body inclined surface (163) positioned at a position facing the first surface (12a) or the second surface (12b) when the battery (12) is coupled to the battery coupling portion (16). The main body inclined surface (163) may be inclined at an angle corresponding to the degree to which the first surface (12a) or the second surface (12b) of the battery (12) coupled to the battery coupling portion (16) is inclined.

[0156] The main body electrode (161) can be placed on the main body inclined surface (163). The main body electrode (161) placed on the main body inclined surface (163) can be inclined in the same manner as the main body inclined surface (163).

[0157] When the battery (12) is connected to the battery connection part (16), the body electrode (161) and the battery electrode (121) that are inclined at a predetermined angle with respect to the length direction of the battery (12) can be electrically connected.

[0158] The battery electrode (121) is arranged to be inclined at a predetermined angle with respect to the longitudinal direction of the battery (12), and the body electrode (161) is also arranged to be inclined at a predetermined angle with respect to the longitudinal direction of the battery (12), so that the degree of freedom in the insertion direction of the battery (12) for coupling to the battery coupling portion (16) can be improved, and damage to the body electrode (161) and / or the battery electrode (121) can be prevented.

[0159] For example, if the body electrode (161) is positioned toward the -y direction as in Fig. 7, there is no problem when the battery (12) moves in the +y direction and is coupled, but if the battery (12) moves in the -x direction and is coupled, the protruding area of ​​the body electrode (161) may be damaged by the battery (12), and if the protrusion of the body electrode (161) is severe, the battery (12) may be caught by the body electrode (161) and it may be difficult to couple it to the battery coupling portion (16).

[0160] Referring to Fig. 9a, when the battery cover (17) is moved to the open position, the battery (12) can be coupled to the battery coupling portion (16) in the -x direction. At this time, the main body electrode (161) can be arranged to be inclined in the longitudinal direction of the battery (12), and the battery electrode (121) can also be arranged to be inclined in the longitudinal direction of the battery (12) so as to be electrically connected to each other. At this time, there is little concern that the inclined main body electrode (161) will be damaged by the battery (12), and there is also little concern that it will interfere with the coupling of the battery (12).

[0161] For another example, referring to FIG. 9b, when the battery cover (17) is moved to the open position, the battery (12) can be coupled to the battery coupling portion (16) in the +y direction. At this time, the main body electrode (161) can be arranged to be inclined in the longitudinal direction of the battery (12), and the battery electrode (121) can also be arranged to be inclined in the longitudinal direction of the battery (12) so as to be electrically connected to each other. At this time, there is little concern that the inclined main body electrode (161) will be damaged by the battery (12), and there is also little concern that it will interfere with the coupling of the battery (12).

[0162] In summary, since the battery electrode (121) and the body electrode (161) are arranged at an angle with respect to the longitudinal direction of the battery (12), the degree of freedom in the bonding direction of the battery (12) can be improved, and the risk of damage to the body electrode (161) by the battery (12) can be reduced.

[0163] A cover electrode (171) and a charging terminal (172) can be placed on the battery cover (17).

[0164] The cover electrode (171) may be configured to electrically connect the charging terminal (172) and the battery electrode (121). The cover electrode (171) may be selectively electrically connected to either the first battery electrode (121a) or the second battery electrode (121b). The cover electrode (171) may connect either the first battery electrode (121a) or the second battery electrode (121b) and the charging terminal (172).

[0165] The cover electrode (171) can be arranged at a predetermined angle with respect to the longitudinal direction of the battery (12). By being inclined at a predetermined angle with respect to the longitudinal direction of the battery (12), the cover electrode (171) can be electrically connected to the battery electrode (121) that is also inclined with respect to the longitudinal direction of the battery (12).

[0166] The charging terminal (172) is configured to charge the battery (12) by supplying power to the battery (12) from an external charger (not shown). The cover electrode (171) can supply power to the battery (12) through the first battery electrode (121a) or the second battery electrode (121b).

[0167] According to the present disclosure, the cover electrode (171) can supply power to the battery (12) only by electrical connection with either the first battery electrode (121a) or the second battery electrode (121b), so that the degree of freedom in the coupling direction of the battery (12) coupled to the battery coupling portion (16) can be improved.

[0168] According to the present disclosure, even if the battery (12) is coupled to the battery coupling portion (16) in a direction different from that shown in FIG. 1, the cover electrode (171) can supply power to the battery (12).

[0169] For example, when the first side (12a) of the battery (12) is connected to the battery coupling portion (16) so that it faces the +y direction, the second battery electrode (121b) can be electrically connected to the cover electrode (171), and power can be supplied to the battery (12) through the second battery electrode (121b).

[0170] As another example, when the second side (12b) of the battery (12) is coupled to the battery coupling portion (16) so that it faces the +y direction, the first battery electrode (121a) can be electrically connected to the cover electrode (171), and power can be supplied to the battery (12) through the first battery electrode (121a).

[0171] Therefore, the direction of coupling of the battery (12) capable of charging the battery (12) is not limited to the direction of coupling illustrated in Fig. 1. The battery (12) can receive power from the cover electrode (171) even when coupled to the battery coupling portion (16) in a state in which the battery (12) is turned upside down in the direction illustrated in Fig. 1.

[0172] According to the present disclosure, the user can operate the aerosol generating device (1) by connecting the battery (12) to the battery connecting portion (16) without paying attention to the connecting direction of the battery (12), thereby improving user convenience and user experience.

[0173] The aerosol generating device (1) may further include a cradle (not shown). The aerosol generating device (1) may be configured as a system together with a separate cradle. The cradle may include a charger capable of charging the battery (12). For example, the cradle may charge the battery (12) of the aerosol generating device (1). Alternatively, the aerosol generator (15) may be heated while the cradle and the aerosol generating device (1) are combined.

[0174] Fig. 10 is a block diagram of an aerosol generating device (1) according to one embodiment of the present disclosure.

[0175] The aerosol generating device (1) may include a battery (12), a control unit (13), a sensor unit (14), an output unit (40), an input unit (70), a communication unit (50), a memory (60), and at least one aerosol generator (15). The aerosol generator (15) may be a stick heater and / or a cartridge heater. However, the internal structure of the aerosol generating device (1) is not limited to that illustrated in Fig. 10. That is, a person 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 components illustrated in Fig. 10 may be omitted or new components may be added.

[0176] The sensor unit (14) can detect the status of the aerosol generating device (1) or the status around the aerosol generating device (1) and transmit the detected information to the control unit (13). Based on the detected information, the control unit (13) can control the aerosol generating device (1) so that various functions such as controlling the operation of the cartridge heater and / or stick heater, restricting smoking, determining whether a stick and / or cartridge (19) is inserted, and displaying a notification are performed.

[0177] The sensor unit (14) may include at least one of a temperature sensor (141), a puff sensor (142), an insertion detection sensor (143), a reuse detection sensor (144), a cartridge detection sensor (145), a cap detection sensor (146), and a movement detection sensor (147).

[0178] The temperature sensor (141) can detect the temperature at which the cartridge heater and / or the stick heater is heated. The aerosol generating device (1) may include a separate temperature sensor that detects the temperature of the cartridge heater and / or the stick heater, or the cartridge heater and / or the stick heater itself may serve as the temperature sensor.

[0179] The temperature sensor (141) can output a signal corresponding to the temperature of the cartridge heater and / or the stick heater. For example, the temperature sensor (141) can include a resistance element whose resistance value changes in response to a change in the temperature of the cartridge heater and / or the stick heater. It can be implemented by a thermistor, which is an element that utilizes the property of changing resistance depending on temperature. At this time, the temperature sensor (141) can output a signal corresponding to the resistance value of the resistance element as a signal corresponding to the temperature of the cartridge heater and / or the stick heater. For example, the temperature sensor (141) can be configured as a sensor that detects the resistance value of the cartridge heater and / or the stick heater. At this time, the temperature sensor (141) can output a signal corresponding to the resistance value of the cartridge heater and / or the stick heater as a signal corresponding to the temperature of the cartridge heater and / or the stick heater.

[0180] A temperature sensor (141) may be placed around the battery (12) to monitor the temperature of the battery (12). The temperature sensor (141) may be placed adjacent to the battery (12). For example, the temperature sensor (141) may be attached to one surface of the battery (12). For example, the temperature sensor (141) may be mounted on one surface of a printed circuit board.

[0181] The temperature sensor (141) is placed inside the main body (10) and can detect the internal temperature of the main body (10).

[0182] The puff sensor (142) can detect the user's puff based on various physical changes in the airflow path. The puff sensor (142) can output a signal corresponding to the puff. For example, the puff sensor (142) can be a pressure sensor. The puff sensor (142) can output a signal corresponding to the internal pressure of the aerosol generating device. Here, the internal pressure of the aerosol generating device (1) can correspond to the pressure of the airflow path through which the gas flows. The puff sensor (142) can be arranged in correspondence to the airflow path through which the gas flows in the aerosol generating device (1).

[0183] The insertion detection sensor (143) can detect the insertion and / or removal of the stick. The insertion detection sensor (143) can detect a signal change according to the insertion and / or removal of the stick.
