[0002] As a substitute for traditional cigarettes, non-combustible smoking devices have quickly attracted people's attention and favor due to their advantages such as safety, convenience, health, and environmental protection in use.

[0003] Currently, the existing power supply box and non-combustible smoking device are usually fixed to each other through a magnetic attraction structure, which easily causes poor electrical contact between them and affects the charging effect. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a power supply box to solve the technical problem that poor electrical contact easily occurs between the existing power supply box and non-combustible smoking device, affecting the charging effect.

[0005] To solve the above technical problem, the embodiments of the present invention provide a power supply box, which adopts the following technical solutions:

[0006] The power supply box includes: a housing, a face cover, and a power supply module;

[0007] The housing has a receiving cavity with one end open, and the receiving cavity is used to receive the smoking device to be charged;

[0008] The power supply module is received in the receiving cavity and includes a power supply and an electrode assembly electrically connected to the power supply, so that when the smoking device to be charged is received in the receiving cavity, the electrode assembly is electrically connected to the smoking device to be charged;

[0009] The face cover is provided with a through hole and is movably connected to the housing, so that the through hole of the face cover communicates with the receiving cavity of the housing or the face cover closes the receiving cavity.

[0010] As a further improvement of the above technical solution, the power supply box further includes a first magnetic attraction structure disposed between the face cover and the housing, so that when the through hole communicates with the receiving cavity of the housing or the face cover closes the receiving cavity, the face cover is fixed to the housing by the magnetic attraction force formed by the first magnetic attraction structure.

[0011] As a further improvement of the above technical solution, the face cover is provided with a first limiting portion, and the housing is provided with a second limiting portion, and the first limiting portion and the second limiting portion are cooperatively arranged, so that the face cover moves relative to the housing to the position where the through hole communicates with the receiving cavity or the face cover closes the receiving cavity under the limiting action of the first limiting portion and the second limiting portion.

[0012] As a further improvement of the above technical solution, the electrode assembly is movably arranged in the accommodating cavity. The power supply box further includes a power assembly, which is arranged in the accommodating cavity and is used to generate a driving force towards the opening direction, so that the driving force drives the electrode assembly to move towards the opening.

[0013] As a further improvement of the above technical solution, a second magnetic attraction structure is provided on the electrode assembly. The power assembly includes a third magnetic attraction structure, which is arranged on the side of the housing away from the opening and has the same magnetism as the second magnetic attraction structure, so as to cooperate with the second magnetic attraction structure to generate the driving force.

[0014] As a further improvement of the above technical solution, the power assembly includes an elastic member, and both ends of the elastic member are respectively abutted against the electrode assembly and the housing to generate the driving force.

[0015] As a further improvement of the above technical solution, the power assembly further includes a catch.

[0020] The power supply box is combined with a housing, a face cover and a power module, and can quickly charge the smoking device to be charged. Among them, by setting the face cover to be movably connected to the housing, the through hole of the face cover can be communicated with the accommodating cavity of the housing or the face cover can close the accommodating cavity. When it is necessary to charge the smoking device to be charged, the face cover is moved relative to the housing to open the opening of the accommodating cavity of the power supply box, which is convenient for inserting the smoking device to be charged and taking out the smoking device to be charged after charging is completed. During the charging process and after the smoking device to be charged is taken out, the face cover is moved relative to the housing again to block the opening of the accommodating cavity. The operation is simple and convenient.

For example, when an element is referred to as being "connected to" another element, it may be directly or indirectly connected to the other element.

[0043] In addition, reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] It should be noted that if Figure 4 and Figure 9 As shown, the power box 100 is mainly used to charge the smoking device 200 to be charged, wherein the smoking device 200 to be charged can be an aerosol generating device. Specifically, aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium. The aerosol generating device includes an atomizer. The aerosol generating device atomizes the atomizing liquid through a built-in atomizer, wherein the atomizer of the aerosol generating device is provided with a liquid storage tank, a liquid injection hole and an atomizing core. The user injects the atomizing liquid into the liquid storage tank from the liquid injection hole. When using the aerosol generating device, the atomizing core atomizes the atomizing liquid in the liquid storage tank to generate smoke for inhalation.

[0045] The embodiment of the present invention provides a power supply box 100, such as Figure 1 , Figure 4 and Figure 9As shown, the smoking device 200 to be charged can be accommodated in the power box 100 for charging; specifically in this embodiment, the power box 100 is used to charge the aerosol generating device, and when the aerosol generating device is charged, it can be separately pulled out of the power box 100 to form a portable suction device.

[0046] like Figure 1 , Figure 6 and Figure 15 As shown, the power box 100 includes a shell 1, a cover 2 and a power module 3; the shell 1 has a receiving cavity (not shown) with an opening at one end, and the receiving cavity is used to receive the smoking device 200 to be charged; the power module 3 is received in the receiving cavity and includes a power supply 31 and an electrode assembly 32 electrically connected to the power supply 31, so that when the smoking device 200 to be charged is received in the receiving cavity, the electrode assembly 32 is electrically connected to the smoking device 200 to be charged. It can be understood that when the smoking device 200 to be charged needs to be charged, the smoking device 200 to be charged is plugged into the receiving cavity, at which time the electrode assembly 32 is electrically connected to the smoking device 200 to be charged, and the power supply 31 can quickly charge the smoking device 200 to be charged.

[0047] like Figure 1 and Figure 5 As shown, the cover 2 is provided with a through hole 21 and is movably connected to the housing 1, so that the through hole 21 of the cover 2 is connected to the housing 1 or the cover 2 closes the housing. Specifically in this embodiment, the cover 2 can be rotated around the central axis of the housing 1 so that the through hole 21 of the cover 2 is connected to or staggered with the housing 1. It can be understood that when the smoking device 200 to be charged needs to be plugged into the housing of the power box 100 for charging, the cover 2 is moved relative to the housing 1 until the through hole 21 of the cover 2 is connected to the housing 1, and an external force is applied to make the smoking device 200 to be charged pass through the through hole 21 and enter the housing, so that the smoking device 200 to be charged is electrically connected to the electrode assembly 32, and the power supply 31 can charge the smoking device 200 to be charged, and then the cover 2 is moved relative to the housing 1 again to close the housing, and the cover 2 can block the housing of the housing 1.

[0048] In summary, compared with the prior art, the power supply box 100 has at least the following beneficial effects: The power supply box 100 can quickly charge the smoking device 200 to be charged through the cooperation of the housing 1, the face cover 2 and the power module 3. Among them, by setting the face cover 2 to be movably connected to the housing 1, the through hole 21 of the face cover 2 can be communicated with the accommodating cavity of the housing 1 or the face cover 2 can close the accommodating cavity. When it is necessary to charge the smoking device 200 to be charged, the face cover 2 is moved relative to the housing 1 to open the opening of the accommodating cavity of the power supply box 100, which is convenient for the smoking device 200 to be charged to be inserted and taken out after charging is completed. During the charging process and after the smoking device 200 to be charged is taken out, the face cover 2 is moved relative to the housing 1 again to block the opening of the accommodating cavity. The operation is simple and convenient. On the one hand, it can prevent foreign objects from falling into the accommodating cavity, has a good dust-proof effect, and avoids affecting the contact effect between the electrode assembly 32 and the smoking device 200 to be charged. On the other hand, it can effectively prevent the smoking device 200 to be charged from detaching from the opening of the accommodating cavity, effectively avoiding the smoking device 200 to be charged from detaching from the electrode assembly 32, thereby improving the charging effect and the aesthetic effect.

[0049] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] In some embodiments, as Figure 1 and Figure 2 shown, the power supply box 100 further includes a first magnetic attraction structure 4 disposed between the face cover 2 and the housing 1; so that when the through hole 21 of the face cover 2 is communicated with the accommodating cavity of the housing 1 or the face cover 2 closes the accommodating cavity, the face cover 2 is fixed to the housing 1 by the magnetic attraction force formed by the first magnetic attraction structure 4. It can be understood that by setting the first magnetic attraction structure 4, a quick positioning effect can be formed on the face cover 2, so that when the face cover 2 moves relative to the housing 1 to the state where the through hole 21 is communicated with the accommodating cavity of the housing 1 or the face cover 2 closes the accommodating cavity, the face cover 2 can be quickly fixed to the housing 1 by the magnetic attraction force formed by the first magnetic attraction structure 4.

[0051] In some embodiments, as Figure 3 shown, the face cover 2 is provided with a first limiting portion 24, and the housing 1 is provided with a second limiting portion 11. The first limiting portion 24 and the second limiting portion 11 are cooperatively arranged so that the face cover 2 moves relative to the housing 1 to the state where the through hole 21 is communicated with the accommodating cavity or the face cover 2 closes the accommodating cavity under the limiting action of the first limiting portion 24 and the second limiting portion 11. It can be understood that by setting the first limiting portion 24 and the second limiting portion 11, when the face cover 2 moves to drive the first limiting portion 24 to the position where it cooperates with the second limiting portion 11, at this time, the face cover 2 moves to the state where the through hole 21 is communicated with the accommodating cavity or moves to the state where the face cover 2 closes the accommodating cavity, so that the face cover 2 can move in a directional manner and quickly move to the preset position.

[0052] In some embodiments, as Figure 3 shown, the face cover 2 includes a cover body 22, a rotating shaft 23, and a limiting member 24, wherein the above-mentioned first limiting portion 24 is the limiting member 24. One side of the cover body 22 close to the housing 1 is rotatably mounted on the housing 1 through the rotating shaft 23. Specifically, in this embodiment, the rotating shaft 23 is disposed at the central position of the cover body 22 so that the cover body 22 can rotate smoothly through the rotating shaft 23. The limiting member 24 is mounted on the rotating shaft 23, and the face cover 2 can drive the limiting member 24 to rotate synchronously when rotating; a limiting groove 11 is formed on one side of the housing 1 close to the cover body 22, wherein the above-mentioned second limiting portion 11 is the limiting groove 11, and the limiting member 24 is received in the limiting groove 11 and rotates in the limiting groove 11. It can be understood that by providing the limiting groove 11, the cover body 22 drives the limiting member 24 to rotate in the limiting groove 11 when rotating. When the cover body 22 rotates to drive the limiting member 24 to reach the edge of the limiting groove 11, the limiting groove 11 blocks the further rotation of the limiting member 24 to block the further rotation of the cover body 22, so that the face cover 2 can be rotated directionally and the face cover 2 can be quickly rotated to a preset position. Specifically, in this embodiment, the cross-section of the limiting groove 11 is in a semi-circular structure, and the limiting member 24 can rotate within a range of 180° along the arc structure of the limiting groove 11. Of course, in other embodiments, the shape of the limiting groove 11 is not limited to the above shape and can be specifically set according to actual needs.

[0053] In some embodiments, as Figure 1 shown, there are two accommodation cavities, and there are two through holes 21 on the face cover 2, and the accommodation cavities correspond to the through holes 21 one by one. It can be understood that by providing two accommodation cavities, the two accommodation cavities can accommodate two smoking devices to be charged 200 at the same time, so as to charge the two smoking devices to be charged 200 at the same time and improve the charging efficiency. Of course, in other embodiments, the number of the accommodation cavities includes but is not limited to two, and can also be one or more than two; correspondingly, the number of the through holes 21 includes but is not limited to two, and can also be one or more than two, and the number of the through holes 21 can be less than the number of the accommodation cavities.

[0054] In some embodiments, as Figure 7 shown, the electrode assembly 32 is movably disposed in the accommodation cavity, and the power supply box 100 further includes a power assembly 5. The power assembly 5 is disposed in the accommodation cavity and is used to generate a driving force toward the opening direction, so that the driving force drives the electrode assembly 32 to move toward the opening. It can be understood that the smoking device to be charged 200 can be inserted and received in the accommodation cavity in the housing 1 for charging by overcoming the driving force with an external force. When the charging is completed, the driving force can automatically drive the smoking device to be charged 200 to pop out of the accommodation cavity, which is convenient for taking the smoking device to be charged 200.

[0055] In some embodiments, asFigure 15 As shown, a second magnetic attraction structure 324 is provided on the electrode assembly 32. The power assembly 5 includes a third magnetic attraction structure 51. The third magnetic attraction structure 51 is disposed on a side of the housing 1 away from the opening and has the same magnetism as the second magnetic attraction structure 324, so as to cooperate with the second magnetic attraction structure 324 to generate the above-mentioned driving force, thereby being able to drive the electrode assembly 32 to move toward the side close to the opening, facilitating the ejection of the smoking device 200 to be charged from the power box 100 after charging is completed.

[0056] In some embodiments, as Figure 8 shown, the power assembly 5 includes an elastic member 52. Two ends of the elastic member 52 respectively abut against the electrode assembly 32 and the housing 1 to generate a driving force. It can be understood that by providing the elastic member 52 between the electrode assembly 32 and the housing 1, the elastic member 52 can form an elastic buffering effect on the electrode assembly 32, so as to form the above-mentioned driving force on the electrode assembly 32 to drive the electrode assembly 32 to move toward the side close to the opening, facilitating the ejection of the smoking device 200 to be charged from the power box 100 after charging is completed. Cooperating with the driving force formed by the above-mentioned second magnetic attraction structure 324 and third magnetic attraction structure 51, the smoking device 200 to be charged can be further ejected from the power box 100 quickly and effectively. It should be noted that the elastic member 52 can specifically be a spring or other elastic components, and no special limitation is made here.

[0057] In some embodiments, as Figure 7 and Figure 8As shown, the power assembly 5 further includes a hook 53, one end of which is connected to the housing 1 or the electrode assembly 32, and the other end of the hook 53 is hooked to the electrode assembly 32 or the housing 1 under the action of a driving force, or the other end of the hook 53 is released from the hooked state under the action of an external force in the opposite direction of the driving force. It can be understood that since the electrode assembly 32 and the housing 1 can be hooked by the hook 53 under the action of a driving force, or released from the hooked state under the action of an external force in the opposite direction of the driving force, the electrode assembly 32 can be fixed relative to the housing 1, so that the smoking device 200 to be charged can be inserted into or released from the accommodating cavity. When the smoking device 200 to be charged is inserted into the accommodating chamber for charging, the smoking device 200 to be charged can be pressed by applying an external force in the opposite direction of the driving force, thereby driving the electrode assembly 32 to move toward the side away from the opening. After the pressing is completed, the hook 53 is in a hooked state under the action of the driving force, so that the electrode assembly 32 is fixed at a preset position relative to the shell 1. At this time, the smoking device 200 to be charged can be completely inserted into the accommodating chamber and the opening of the accommodating chamber is blocked by the cover 2 to prevent the smoking device 200 to be charged from being detached from the opening of the accommodating chamber. The smoking device 200 to be charged is in contact with the electrode assembly 32 and electrically connected; when charging is completed, the cover 2 is moved relative to the shell 1 to open the opening of the accommodating chamber of the power box 100, and the smoking device 200 to be charged is pressed again. The electrode assembly 32 is detached from the hooked state under the action of an external force in the opposite direction of the driving force, and then the electrode assembly 32 is driven to move toward the side close to the opening by the driving force, driving the smoking device 200 to be charged to automatically pop out of the power box 100.

[0058] In some embodiments, Figure 7 , Figure 8 , Figure 12 and Figure 13As shown, a card slot group 54 is provided on the electrode assembly 32 or the housing 1. The card slot group 54 includes a first card slot 541 and a guiding slot 542. One end of the guiding slot 542 communicates with the first card slot 541, so that the other end of the catch 53 slides along the guiding slot 542 to the first card slot 541 under the action of a driving force to hook tightly to the electrode assembly 32 or the housing 1, or the other end of the catch 53 slides along the first card slot 541 to the guiding slot 542 under the action of an external force to disengage from the hooking state. It can be understood that through the cooperation of the first card slot 541, the guiding slot 542 and the catch 53, when the smoking device 200 to be charged is inserted into the accommodating cavity for charging, an external force opposite to the direction of the driving force can be applied to press the smoking device 200 to be charged, thereby driving the electrode assembly 32 to move towards the side away from the opening. The catch 53 slides into the first card slot 541 from the guiding slot 542 accordingly. When the pressing stops, at this time, the catch 53 is in a hooking state under the action of the driving force, so that the electrode assembly 32 is fixed relative to the housing 1 at a preset position; when the charging is completed, the smoking device 200 to be charged is pressed again, and the catch 53 disengages from the first card slot 541 and slides to the guiding slot 542 under the action of an external force opposite to the driving force to disengage from the hooking state. At this time, the electrode assembly 32 moves towards the side close to the opening under the action of the driving force, driving the smoking device 200 to be charged to automatically pop out of the power box 100.

[0059] In some embodiments, as Figure 8 shown, the extending direction of the first card slot 541 is inclined relative to the driving force direction, and the extending direction of the guiding slot 542 is parallel to the driving force direction, so as to facilitate the catch 53 to smoothly slide from the guiding slot 542 to the first card slot 541 and be able to hook tightly to the first card slot 541, or to smoothly slide out of the first card slot 541 to the guiding slot 542 to disengage from the hooking state under the action of an external force opposite to the driving force direction.

[0060] In some embodiments, as Figure 8 shown, the card slot group 54 further includes a second card slot 543. The second card slot 543 communicates with the other end of the guiding slot 542 and is inclined relative to the driving force direction. In one specific embodiment, the specific setting of the card slot group 54 is as follows: along the central line direction of the accommodating cavity, the outer peripheral wall of the electrode assembly 32 is sequentially provided with the first card slot 541 and the second card slot 543, and the guiding slot 542 connecting the first card slot 541 and the second card slot 543 respectively, wherein the first card slot 541 is located between the second card slot 543 and the face cover 2; a catch 53 is provided at one end of the housing 1 away from the face cover 2, and the catch 53 can slide along the guiding slot 542 to hook tightly to the first card slot 541 or the second card slot 543. It can be understood that, as Figure 8 shown, when the smoking device 200 to be charged is not inserted into the accommodating cavity, at this time, the catch 53 hooks tightly to the second card slot 543; as Figures 12 to 14As shown, when the smoking device 200 to be charged is plugged into the accommodation cavity for charging, the smoking device 200 to be charged can be pressed to drive the electrode assembly 32 to move towards the hook 53. At this time, the hook 53 leaves the second card slot 543 under the guiding action of the guiding groove 542 and then reaches the first card slot 541. At this time, the pressing of the smoking device 200 to be charged is stopped. Under the action of the driving force, the hook 53 is hooked tightly in the first card slot 541 to relatively fix the electrode assembly 32 on the housing 1. At this time, the smoking device 200 to be charged is completely plugged into the accommodation cavity, and the smoking device 200 to be charged is in contact with the electrode assembly 32 and electrically connected for charging; after the charging is completed, the smoking device 200 to be charged is pressed again, and the hook 53 disengages from the first card slot 541 to disengage the hooked state. At this time, the pressing is stopped, and the hook 53 leaves the first card slot 541 under the guiding action of the guiding groove 542 and returns to the second card slot 543 again. At this time, the electrode assembly 32 moves in the direction away from the hook 53, driving the smoking device 200 to be charged to automatically pop out of the power box 100. It should be noted that in other embodiments, the card slot group 54 can be similarly set as follows: along the central line direction of the accommodation cavity, a first card slot 541 and a second card slot 543 are opened on the housing 1, and guiding grooves 542 connecting the first card slot 541 and the second card slot 543 respectively; a hook 53 is provided at one end of the electrode assembly 32 away from the face cover 2, and the hook 53 can slide along the guiding groove 542 to hook tightly in the first card slot 541 or the second card slot 543.

[0061] In some embodiments, the number of the card slot groups 54 is two, and the two card slot groups 54 are symmetrically arranged with each other. The two first card slots 541 communicate with each other, and the two second card slots 543 communicate with each other. Specifically, in this embodiment, as Figure 8 shown, the two first card slots 541 cooperate to form a V-shaped groove, and the two second card slots 543 cooperate to form a V-shaped groove. The opening direction of the V-shaped groove is opposite to the opening direction of the hook 53, which is convenient for the hook 53 to be hooked tightly in the V-shaped groove. In addition, it can be understood that since the face cover 2 is fixed to the housing 1 through the first magnetic attraction structure 4, the first magnetic attraction structure 4, the card slot group 54 and the hook 53 can cooperate to jointly fix and limit the opposite two ends of the smoking device 200 to be charged, which can further improve the contact effect between the electrode assembly 32 and the smoking device 200 to be charged and improve the charging effect.

[0062] In some embodiments, as Figure 10 and Figure 11As shown, the electrode assembly 32 can form a magnetic attraction effect with the smoking device 200 to be charged through the second magnetic attraction structure 324, so that the smoking device 200 to be charged is firmly abutted against the electrode assembly 32, improving the contact stability between the two, effectively avoiding poor contact between the smoking device 200 to be charged and the electrode assembly 32 of the power supply box 100, and thus further improving the charging effect. In a specific embodiment, a fourth magnetic attraction structure is provided at one end of the smoking device 200 close to the electrode assembly 32, and the polarity of the fourth magnetic attraction structure is opposite to that of the second magnetic attraction structure 324. The electrode assembly 32 can be tightly abutted against the smoking device 200 through the magnetic attraction force formed by the fourth magnetic attraction structure and the second magnetic attraction structure 324.

[0063] In some embodiments, as Figure 15 shown, the electrode assembly 32 includes a body 321, a first electrode body 322 and a second electrode body 323. The second magnetic attraction structure 324, the first electrode body 322 and the second electrode body 323 are all arranged on the side of the body 321 close to the smoking device 200 to be charged; wherein the polarities of the first electrode body 322 and the second electrode body 323 are opposite. Specifically, in this embodiment, the first electrode body 322 is a negative electrode body, and the second electrode body 323 is a positive electrode body. Correspondingly, a positive electrode body and a negative electrode body are provided on the smoking device 200 to be charged. When the smoking device 200 to be charged is magnetically attracted to the second magnetic attraction structure 324 through the fourth magnetic attraction structure, the first electrode body 322 contacts the negative electrode body of the smoking device 200 to be charged, and the second electrode body 323 contacts the positive electrode body of the smoking device 200 to be charged to form a conduction circuit.

[0064] It should be noted that, specifically, in this embodiment, as Figure 15 shown, the cross-section of the fourth magnetic attraction structure is a closed ring, and the cross-section of the second magnetic attraction structure 324 can be adaptively set to an arc shape or a closed ring shape; when the cross-section of the second magnetic attraction structure 324 is an arc shape, there are at least two second magnetic attraction structures 324, and each second magnetic attraction structure 324 is evenly arranged on the body 321; the cross-section of the third magnetic attraction structure 51 is circular. Of course, in other embodiments, the second magnetic attraction structure 324, the third magnetic attraction structure 51 and the fourth magnetic attraction structure can be other suitable shapes, which are not particularly limited here.

[0065] In some embodiments, as Figure 2As shown, the first magnetic attraction structure 4 includes a first magnetic member 41 and a second magnetic member 42 that are magnetically attracted to each other, wherein the first magnetic member 41 is arranged on a side of the face cover 2 close to the shell 1, and the second magnetic member 42 is arranged on a side of the shell 1 close to the face cover 2, and the face cover 2 is fixed to the shell 1 by the attraction between the first magnetic member 41 and the second magnetic member 42. In addition, it should be noted that, in this embodiment, a suitable number of second magnetic members 42 can be arranged on the shell 1 according to the movement of the face cover 2 on the shell 1, that is, the second magnetic member 42 can be correspondingly arranged at the position where the face cover 2 moves to the position, so as to facilitate the rapid adjustment of the connection or staggered state between the through hole 21 of the face cover 2 and the accommodating cavity of the shell 1.

[0066] The working process of the power box 100 in one specific embodiment is briefly described below:

[0067] When the smoking device 200 to be charged needs to be plugged into the accommodating chamber of the power box 100 for charging, the cover 2 is rotated to rotate around the central axis of the shell 1. When the through hole 21 of the cover 2 is connected to the accommodating chamber of the shell 1, the smoking device 200 to be charged is pressed to allow the smoking device 200 to pass through the through hole 21 and enter the accommodating chamber. After entering the accommodating chamber, the smoking device 200 to be charged contacts the electrode assembly 32. At this time, the smoking device 200 to be charged has not completely entered the accommodating chamber. The smoking device 200 to be charged continues to be pressed and drives the electrode assembly 32 to move toward the bottom end of the shell 1 (i.e., the end away from the cover 2), thereby driving the hook 53 from the second slot 543 at the initial position along the guide slot 542 to the first slot 541. At this time, the pressing of the smoking device 200 to be charged is stopped. The hook 53 is hooked tightly to the first slot 541 under the driving force of the power assembly 5. When the smoking device 200 to be charged completely enters the accommodating chamber, and the smoking device 200 to be charged is magnetically connected to the electrode assembly 32 to form an electrically conductive state, and the power supply 31 charges the smoking device 200 to be charged; at this time, the cover 2 can be rotated again around the central axis of the shell 1 until the through hole 21 of the cover 2 is offset from the accommodating chamber of the shell 1, so that the cover 2 can block the accommodating chamber of the shell 1; after charging is completed, the cover 2 is rotated to open the opening of the accommodating chamber, and the smoking device 200 to be charged is pressed to make the hook 53 leave the first slot 541 to disengage from the hooked state, and under the action of the driving force, it leaves the first slot 541 and returns to the second slot 543 along the guiding action of the guide slot 542. At this time, the electrode assembly 32 moves in the direction away from the hook 53, driving the smoking device 200 to be charged to automatically pop out of the power box 100, and the smoking device 200 to be charged can be pulled out by hand.
