And the accommodating cavity 101 and the installation cavity 102 are sequentially arranged along the first direction, both the accommodating cavity 101 and the installation cavity 102 extend along the second direction, the installation cavity 102 includes the first cavity 1021 and the second cavity 1022 distributed along the second direction, the power supply device 2 is disposed in the first cavity 1021, and the circuit board 3 is disposed in the second cavity 1022, which is beneficial to realizing the uniform distribution of the aerosol generating device, the power supply device 2 and the circuit board 3 on the mounting base 1, making the structure of the charging device 100 compact, avoiding the oversize of the charging device 100 in any direction, and being convenient to carry.

[0047] Exemplarily, the first direction can be as shown in the Y0 - Y1 direction in Figure 1 and the second direction can be as shown in the X0 - X1 direction in Figure 1 .

[0048] Specifically, the length direction of the charging device 100 can be the second direction. When the aerosol generating device is disposed in the accommodating cavity 101, the length direction of the aerosol generating device can be parallel to the second direction.

[0049] Exemplarily, the power supply device 2 can include one or more batteries. When there is one battery, the length direction of the battery can be arranged along the second direction. When there are multiple batteries, the multiple batteries can be arranged along the second direction.

[0050] Exemplarily, the circuit board 3 can extend along the second direction to expand the area of the circuit board 3 so that the circuit board 3 has enough area to arrange predetermined components.

[0051] As Figures 4 to 6 shown, in some embodiments, the mounting base 1 includes a bracket 11 and a housing 12. The bracket 11 is disposed in the housing 12. The bracket 11 is provided with the accommodating cavity 101, and the bracket 11 and the housing 12 enclose to form the installation cavity 102. It can be understood that by assembling the bracket 11 and the housing 12 to form the mounting base 1, after the circuit board 3, the power supply device 2 and the charging structure 4 are mounted on the bracket 11, the circuit board 3, the power supply device 2 and the charging structure 4 can be mounted in the housing 12 together with the bracket 11, improving the assembly convenience of the charging device 100. At the same time, the housing 12 and the bracket 11 jointly form the installation cavity 102, which can play a role in protecting the circuit board 3, the power supply device 2 and the charging structure 4.

[0052] AsFigure 6 As shown, further, the bracket 11 includes a first main body portion 111, a first side portion 112 and a second side portion 113.

It can be understood that the first side portion 112 and the second side portion 113 are respectively provided on opposite sides of the first main body portion 111. The first main body portion 111, the first side portion 112 and the second side portion 113 enclose a receiving cavity 101. The first side portion 112 and the second side portion 113 are spaced apart, so that the bracket 11 forms a first opening 1011 of the receiving cavity 101 in a direction perpendicular to the second direction, and the first opening 1011 extends along the second direction. The diameter of the first opening 1011 is relatively large, which facilitates the aerosol generating device to be placed in the receiving cavity 101 from the first opening 1011. And the power connection portion can be provided on the first side portion 112, and the power supply device 2 and the circuit board 3 can be provided on the first main body portion 111, realizing the stable installation of the circuit board 3, the power supply device 2 and the power connection portion.

[0053] Exemplarily, the power supply device 2 can be connected to the first main body portion 111 by one or more of clamping, gluing and other methods. For example Figure 6 As shown, the first main body portion 111 includes a connecting portion 1111 and an extending portion. The first side portion 112 and the second side portion 113 are provided on opposite sides of the connecting portion 1111 along the second direction. The connecting portion 1111, the first side portion 112 and the second side portion 113 enclose a receiving cavity 101. The extending portion is provided on a side of the connecting portion 1111 away from the receiving cavity 101 along the first direction. The extending portion includes a first extending portion 1112a and a second extending portion 1112b that are arranged oppositely along the second direction, and a third extending portion 1112c and a fourth extending portion 1112d that are arranged oppositely along a third direction as shown in the Z0-Z1 direction. The first direction, the second direction and the third direction are perpendicular to each other. The connecting portion 1111 and the extending portion enclose a first groove 111a. The power supply device 2 can be partially located in the first groove 111a, realizing the positioning of the power supply device 2 in the first main body portion 111, and can be connected to the connecting portion 1111 by gluing, realizing the installation of the power supply device 2.

[0054] Exemplarily, the circuit board 3 can be connected to the first main body by one or more of clamping, gluing, screw connection and other methods.

[0055] Exemplarily, the bracket 11 can be connected to the outer shell 12 by one or more of gluing, clamping, screw connection and other methods.

[0056] As Figure 6 and Figure 7 shown, the housing 12 includes a second main body portion 121. On opposite sides of the second main body portion 121 along the second direction, a third side portion 122 and a fourth side portion 123 are respectively provided. The bracket 11 is located between the first side portion 112 and the second side portion 113. The first main body portion 111 is connected to the second main body portion 121, the first side portion 112 is connected to the third side portion 122, and the second side portion 113 is connected to the fourth side portion 123, ensuring the connection stability between the bracket 11 and the housing 12. For example, the first side portion 112 is snap-connected to the third side portion 122, and the second side portion 113 is fastened to the fourth side portion 123 by screws. The second main body portion 121 forms a second groove 1211. The extension portion of the first main body portion 111 can be located within the second groove 1211. First locking blocks 1113 are provided on both the third extension portion 1112c and the fourth extension portion 1112d. A plurality of first locking slots 1212 are provided on the wall surface of the second groove 1211 of the second main body portion 121. The plurality of first locking blocks 1113 are respectively snap-connected to the plurality of first locking slots 1212, realizing the snap connection between the first main body portion 111 and the second main body portion 121.

[0057] As Figure 2 shown, in some embodiments, the charging device 100 further includes a first cover body 5. The first cover body 5 is movably connected to the mounting base 1. The first cover body 5 is used to close or open the accommodation cavity 101. It can be understood that the accommodation cavity 101 has a first opening 1011. The aerosol generating device can be placed in the accommodation cavity 101 through the first opening 1011. By movably connecting the first cover body 5 to the mounting base 1, the first cover body 5 can close or open the first opening 1011 to close or open the accommodation cavity 101, playing a role in protecting the aerosol generating device and the power connection part, and avoiding the aerosol generating device and the power connection part from being damaged by collision.

[0058] Wherein, the first cover body 5 being movably connected to the mounting base 1 may include one or more of the following situations: the first cover body 5 is slidably connected to the mounting base 1; the first cover body 5 is rotatably connected to the mounting base 1; the first cover body 5 is magnetically connected to the mounting base 1; the first cover body 5 is detachably snap-connected to the mounting base 1.

[0059] In some embodiments, the first cover body 5 includes a flexible cover body, which is more convenient to control the movement of the first cover body 5 to open the accommodation cavity 101.

[0060] In some embodiments, opposite ends of the first cover body 5 are respectively connected to opposite sides of the bracket 11 and / or the housing 12 along the third direction. For example Figure 6 and Figure 7As shown, a third groove is provided on a side of the third extension portion 1112c facing away from the fourth extension portion 1112d. A first magnetic attraction member 61 is provided in the third groove. A fourth groove is provided on a side of the fourth extension portion 1112d facing away from the third extension portion 1112c. A second magnetic attraction member 62 is provided in the fourth groove. The first magnetic attraction member 61 and the second magnetic attraction member 62 are magnetically connected to opposite sides of the flexible cover body respectively, realizing the movable connection between the bracket 11 and the first cover body 5. By applying an external force to control the first cover body 5 to overcome the magnetic attraction force, the relative movement of the first cover body 5 with respect to the bracket 11 can be controlled to open the accommodation cavity 101. Moreover, the first magnetic attraction member 61 is provided in the third groove of the third extension portion 1112c, and the second magnetic attraction member 62 is provided in the fourth groove of the fourth extension portion 1112d, improving the utilization rate of the space on the bracket 11 and facilitating the realization of the compact structure of the charging device 100.

[0061] It can be understood that the first cavity 1021 and the second cavity 1022 are sequentially distributed in the second direction, as Figure 2 and Figure 4 shown. The first cavity 1021 can be located on the X1 side of the mounting base 1, on a side of the first cavity 1021 close to the accommodation cavity 101 where the power connection portion is provided, while the second cavity 1022 is located on the X0 side of the mounting base 1, on a side of the second cavity 1022 far from the accommodation cavity 101 where the power connection portion is provided. At this time, the charging structure 4 can extend from the second cavity 1022 through the first cavity 1021 and then towards the accommodation cavity 101, so that the power connection portion of the charging structure 4 is exposed in the accommodation cavity 101. Alternatively, the second cavity 1022 can be arranged on a side close to the accommodation cavity 101 where the power connection portion is provided, while the first cavity 1021 is arranged on a side far from the accommodation cavity 101 where the power connection portion is provided. The charging structure 4 can extend from the first cavity 1021 towards the accommodation cavity 101, so that the power connection portion of the charging structure 4 is exposed in the accommodation cavity 101. It can be specifically adjusted according to the actual situation.

[0062] As Figure 3 and Figure 4 shown. In some embodiments, the mounting base 1 is further provided with a power connection cavity 103. The power connection cavity 103 is located on a side of the accommodation cavity 101 where the power connection portion is provided. The power connection cavity 103 communicates with the accommodation cavity 101 and the mounting cavity 102. At least a part of the charging structure 4 is located in the power connection cavity 103. It can be understood that the power connection cavity 103 and the mounting cavity 102 are located on the outer periphery of the accommodation cavity 101. The charging structure 4 can extend from the mounting cavity 102 to the power connection cavity 103, so that the charging structure 4 is wound around the outer periphery of the accommodation cavity 101, and only the power connection portion of the charging structure 4 is exposed on one side in the second direction, reducing the mutual interference between the charging structure 4 and the aerosol generating device, and at the same time facilitating the installation of the charging structure 4 and the aerosol generating device.

[0063] Exemplarily, as Figure 4 and Figure 5As shown, the first side portion 112 and the third side portion 122 enclose to form a power connection cavity 103. The first side portion 112 is provided with a first through hole 1121 that communicates the power connection cavity 103 and the accommodation cavity 101. The charging structure 4 can extend from the second cavity 1022 to the power connection cavity 103, and the power connection portion of the charging structure 4 can extend into the accommodation cavity 101 through the first through hole 1121 to contact and conduct with the charging terminal of the aerosol generating device.

[0064] As Figure 3 and Figure 5 shown, further, the charging structure 4 includes a flexible electrical connector 41 and a power connection member 42. The flexible electrical connector 41 is electrically connected to the circuit board 3, and the flexible electrical connector 41 extends from the second cavity 1022 to the power connection cavity 103. One end of the power connection member 42 is connected to the flexible electrical connector 41, and the other end extends into the accommodation cavity 101. It can be understood that the power connection portion includes the power connection member 42, and the flexible electrical connector 41 has better flexibility, which is convenient for its arrangement in a limited space, extending from the second cavity 1022 to the power connection cavity 103 to realize the electrical connection between the power connection member 42 and the circuit board 3.

[0065] Exemplarily, the flexible electrical connector 41 includes, but is not limited to, a flexible circuit board 3, flexible electrical wires, etc.

[0066] Exemplarily, the flexible electrical connector 41 can be connected to the first side portion 112 and / or the third side portion 122 by means of gluing, screw connection, etc.

[0067] Exemplarily, the power connection member 42 can be one or more. The power connection member 42 includes, but is not limited to, pin needles, conducting elastic pieces, etc. As Figure 5 shown, the first side portion 112 is provided with a plurality of first through holes 1121, and a plurality of power connection members 42 can be respectively inserted through the plurality of first through holes 1121 and extend into the accommodation cavity 101. The aperture of the first through hole 1121 can match the outer diameter of the power connection member 42, and the position of the power connection member 42 is defined by the first side portion 122 to improve the installation stability of the power connection member 42.

[0068] Exemplarily, the first through hole 1121 can be a stepped hole, and the power connection member 42 can be clamped in the stepped hole to further improve the connection stability between the power connection member 42 and the first side portion 122.

[0069] As Figure 5 shown, in some embodiments, the charging device 100 further includes a charging interface 7. The charging interface 7 is electrically connected to the circuit board 3, and the charging interface 7 is used to charge the power supply device 2. It can be understood that the charging interface 7 can be connected to an external power source to realize charging the power supply device 2.

[0070] Further, the charging interface 7 is disposed in the second cavity 1022 and on one side of the power supply device 2 along the second direction. It can be understood that the second cavity 1022 can accommodate the power supply device 2. The size of the second cavity 1022 is relatively large, which is more convenient for arranging the charging interface 7, so that the charging interface 7 and the power supply device 2 are distributed along the second direction, which is more conducive to making the arrangement of the charging interface 7 and the power supply device 2 on the mounting base 1 more compact, realizing the structural compactness of the charging device 100 and reducing the volume of the charging device 100.

[0071] As Figure 6 shown, exemplarily, a bearing portion is provided on a side of the fourth extension portion 1112d away from the third extension portion 1112c, and the bearing portion is used to bear the charging interface 7.

[0072] Exemplarily, the charging interface 7 can be electrically connected to the circuit board 3 through a flexible circuit board 3 or a flexible electrical conductor.

[0073] As Figure 2 and Figure 3 shown, in some embodiments, the aerosol generating device includes a main body and a filter connected to the main body. The accommodating cavity 101 includes a third cavity 101a and a fourth cavity 101b that communicate with each other. The first main body portion 111, the first side portion 112, and the second side portion 113 enclose to form the third cavity 101a. The second side portion 113 is provided with the fourth cavity 101b. The main body is disposed in the third cavity 101a, and at least a part of the filter is located in the fourth cavity 101b. The power connection portion is used to make contact conduction with the charging terminal of the main body. It can be understood that the accommodating cavity 101 can accommodate the filter of the aerosol generating device, without disassembling the filter from the main body, simplifying the charging process, and at the same time enhancing the protection effect of the bracket 11 on the aerosol generating device.

[0074] In some embodiments, the filter can be spaced apart from the wall surface of the fourth cavity 101b to reduce the contact between the filter and the charging device 100 to maintain the cleanliness of the filter.

[0075] As Figure 3 shown, in some embodiments, the aerosol generating device is snap-fitted to the first side portion 112 to limit the relative position between the aerosol generating device and the first side portion 112, so that the charging terminal of the aerosol generating device makes stable contact conduction with the power connection portion. For example Figure 3 shown, a second locking block 1122 is provided on a side of the first side portion 112 facing the second side portion 113. When the aerosol generating device is disposed in the accommodating cavity 101, the second locking block 1122 can be snap-fitted into the second card slot of the main body, and a plurality of power connection members 42 can be wound around the outer periphery of the second locking block 1122 and make contact conduction with a plurality of charging terminals of the aerosol generating device.

[0076] As Figure 2 and Figure 5As shown, in some embodiments, the bracket 11 is provided with an elastic component 8. When the aerosol generating device is placed in the accommodating cavity 101, the aerosol generating device contacts the elastic component 8, and the elastic component 8 can provide an elastic force to keep the charging terminal of the main body in contact with the power connection part, improving the electrical conduction stability between the charging terminal of the main body and the power connection part.

[0077] Furthermore, the second side portion 113 is further provided with a mounting hole 1131 communicating with the third cavity 101a. The elastic component 8 includes an elastic member 81 and an abutting member 82. The elastic member 81 is disposed in the mounting hole 1131. The abutting member 82 is connected to the elastic member 81, and at least a part of the abutting member 82 extends into the third cavity 101a, and the abutting member 82 is used to abut against the aerosol generating device. It can be understood that the elastic member 81 provides an elastic force for the abutting member 82, and by abutting the abutting member 82 against the main body, it is beneficial to ensure a reliable connection between the elastic component 8 and the main body.

[0078] Exemplarily, the elastic member 81 includes but is not limited to a spring, a spring sheet, etc.

[0079] Exemplarily, the mounting hole 1131 can be a through hole, and the elastic member 81 and the abutting member 82 are movably disposed in the mounting hole 1131. One end of the elastic member 81 abuts against the third side portion 122, and the other end abuts against the abutting member 82, so that the abutting member 82 at least extends into the third cavity 101a to abut against the main body. A stepped surface can be formed on one side of the mounting hole 1131 close to the third cavity 1131, and the stepped surface is used to abut against the abutting member 82 to limit the movement range of the abutting member 82 and the elastic member 81, preventing the abutting member 82 and the elastic member 81 from disengaging from the mounting hole 1131.

[0080] Exemplarily, as Figure 2 and Figure 5 shown, the elastic member 81 abuts against the outer shell 12 through a base 83, ensuring a reliable connection between the elastic member 81 and the outer shell 12, and at the same time making it easier for the elastic member 81 to be compressed and deformed, so that the elastic member 81 can provide a stable elastic force for the main body. The base 83 can be snap-fitted to the side of the mounting hole 1131 away from the third cavity 1131, improving the mounting stability of the base 83.

[0081] In some embodiments, the abutting member 82 has an arc-shaped abutting surface. By abutting against the main body through the arc-shaped abutting surface, it is convenient for the aerosol generating device to slide along the arc-shaped abutting surface under an external force to overcome the elastic force and push the abutting member 82, so as to place the aerosol generating device in the accommodating cavity 101. At the same time, the arc-shaped abutting surface can reduce the damage of the abutting member 82 to the aerosol generating device.

[0082] Of course, in other embodiments, the elastic component 8 can also be provided on the first main body portion 111 or the outer shell 12, and can be specifically adjusted according to the actual situation.

[0083] AsFigure 5 As shown, in some embodiments, a third magnetic attraction member 63 is further provided on the first side portion 112. The third magnetic attraction member 63 is used for magnetic attraction connection with the host, so that the charging terminal of the host can keep in contact with the power connection portion, improving the electrical conduction stability between the charging terminal of the host and the power connection portion.

[0084] As Figure 5 and Figure 6 As shown, in some embodiments, a convex portion 114 is provided on one side of the first main body portion 111 facing the housing 12 along the first direction. The convex portion 114 is provided with a receiving cavity 1141 for receiving the filter tip of the aerosol generating device. It can be understood that a convex portion 114 is provided on the side of the first main body portion 111 away from the accommodating cavity 101 along the first direction, and the receiving cavity 1141 is used for receiving the spare filter tip of the aerosol generating device, so as to facilitate the user to replace the filter tip on the aerosol generating device as needed.

[0085] Furthermore, the convex portion 114, the first main body portion 111 and the housing 12 enclose a first cavity 1021, and the receiving cavity 1141 is located on one side of the first cavity 1021 along the second direction. The convex portion 114 and the housing 12 enclose a second cavity 1022. Along the first direction, the receiving cavity 1141 is located between the accommodating cavity 101 and the second cavity 1022. It can be understood that the thickness of the circuit board 3 is relatively thin. The convex portion 114 is provided on the side of the first main body portion 111 away from the accommodating cavity 101 so that the receiving cavity 1141 is located between the accommodating cavity 101 and the second cavity 1022, which is beneficial to making the arrangement of the spare filter tip, the circuit board 3 and the power supply device 2 on the bracket 11 more compact, reducing the volume of the charging device 100 and facilitating carrying.

[0086] Exemplarily, as Figures 5 to 7 shown, the receiving cavity 1141 has a second opening 1141a, and the housing 12 is provided with a first avoidance hole 1213 corresponding to the second opening 1141a. The filter tip can be placed in the receiving cavity 1141 through the first avoidance hole 1213 and the second opening 1141a. The convex portion 114 is located on the side of the first main body portion 111 where the second side portion 113 is provided along the second direction, that is, the convex portion 114 is arranged away from the first side portion 112, avoiding the interference caused by the concentrated arrangement of the convex portion 114 and the circuit board 3 near the first side portion 112 to the arrangement of the charging structure 4.

[0087] Exemplarily, as Figure 5 and Figure 6As shown, the convex portion 114 is located on the side of the first main body portion 111 where the second side portion 113 is provided in the second direction. The storage cavity 1141 is isolated from the accommodation cavity 101 to reduce the interference of the filter tip on the aerosol generating device. The second opening 1141a is located on the side of the convex portion 114 away from the first cavity 1021 in the second direction. The third side portion 122 of the outer shell 12 is provided with a first avoidance hole 1213 to facilitate the charging structure 4 to be wound around the outer periphery of the convex portion 114 and the power supply device 2 and extend towards the accommodation cavity 101.

[0088] Of course, in other embodiments, the second opening 1141a of the storage cavity 1141 may also be located on the side of the convex portion 114 close to the first main body portion 111, and the second opening 1141a communicates with the accommodation cavity 101. Alternatively, the second opening 1141a of the storage cavity 1141 is located on one side of the convex portion 114 in the third direction.

[0089] As Figure 5 shown, in some embodiments, the charging device 100 further includes a second cover 9. The second cover 9 is movably connected to the outer shell 12, and the second cover 9 is used to close or open the storage cavity 1141. It can be understood that the storage cavity 1141 has a second opening 1141a, and the filter tip can be placed in the storage cavity 1141 through the second opening 1141a. The second cover 9 is movably connected to the mounting seat 1 so that the second cover 9 can close or open the second opening 1141a to close or open the storage cavity 1141, playing a role in protecting the filter tip and keeping the spare filter tip clean.

[0090] Among them, the second cover 9 being movably connected to the mounting seat 1 may include one or more of the following situations: the second cover 9 is slidably connected to the mounting seat 1; the second cover 9 is rotatably connected to the mounting seat 1; the second cover 9 is magnetically connected to the mounting seat 1; the second cover 9 is detachably snap-connected to the mounting seat 1.

[0091] Exemplarily, the second cover 9 may be movably connected to the outer shell 12.

[0092] Of course, in other embodiments, the filter tip may be snap-connected in the storage cavity 1141 to prevent the filter tip from being pulled out of the storage cavity 1141.

[0093] In some embodiments, functional elements are provided on the circuit board 3. Among them, the functional elements include but are not limited to a light-emitting element 31, a switch 32, a display element, a sensing element, etc.

[0094] Exemplarily, as Figure 4 and Figure 5As shown, the functional element includes a light-emitting element 31 and a switch 32. The switch 32 is used to control the lighting and extinguishing of the light-emitting element 31, and the light-emitting element 31 is used to indicate the power of the charging device 100. The housing 12 is provided with a second avoidance hole 1214, and the second avoidance hole 1214 communicates with the first cavity 1021. The light-emitting element 31 and the switch 32 are passed through the second avoidance hole 1214, so as to facilitate the user to operate the switch 32 and know the power of the charging device 100 from the lighting condition of the light-emitting element 31, and charge the charging device 100 in time.
