This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] This application discloses an electronic atomizing device that allows for the disassembly and replacement of the atomizer 1 and the liquid replenishment component 2, thereby meeting the needs of users for different flavors, extending the service life of the electronic atomizing device, and reducing the cost of using the electronic atomizing device.

[0032] Please refer to the electronic atomizing device of this application embodiment. Figures 1 to 3 The device includes an atomizer 1, a liquid replenishment assembly 2, and a battery assembly 3. The atomizer 1 has an atomization channel 13, an atomizing core 14, and a liquid storage chamber 15. The liquid storage chamber 15 is arranged around the atomization channel 13 and is used to store atomized liquid. The atomizing core 14 is located inside the atomization channel 13 and is used to heat the atomized liquid to generate an aerosol. The generated aerosol can flow out from the atomization channel 13 for the user. The atomizer 1 also has a liquid inlet 16, which communicates with the liquid storage chamber 15 and allows liquid to be replenished into the liquid storage chamber 15 through the liquid inlet 16.

[0033] The replenishment component 2 includes a replenishment bottle 21, which is used to store atomizing liquid. The replenishment component 2 has a liquid outlet 23 that communicates with the internal space of the replenishment bottle 21. The liquid outlet 23 is in fluid communication with the liquid inlet 16 of the atomizer 1. The atomizing liquid in the replenishment bottle 21 can enter the liquid storage chamber 15 through the liquid outlet 23 and the liquid inlet 16 in sequence to replenish the atomizer 1.

[0034] Atomizer 1 and liquid replenishment assembly 2 are arranged along the extension direction of atomization channel 13. At least a portion of battery assembly 3 is located between atomizer 1 and liquid replenishment assembly 2 along the extension direction of atomization channel 13. Both atomizer 1 and liquid replenishment assembly 2 are detachably connected to battery assembly 3. Battery assembly 3 is electrically connected to atomizer core 14 to provide power to atomizer 1. The portion of battery assembly 3 located between atomizer 1 and liquid replenishment assembly 2 has a connecting hole 325 that connects liquid outlet 23 and liquid inlet 16. The extension direction is the same as the extension direction of the atomizing channel 13. The connecting hole 325 has a first hole segment 326 and a second hole segment 327 connected in its extension direction. The hole wall of the liquid inlet hole 16 in the atomizer 1 is sealed with the hole wall of the first hole segment 326. The hole wall of the liquid outlet hole 23 in the liquid replenishment assembly 2 is sealed with the hole wall of the second hole segment 327. In this way, the atomized liquid can be sealed through the channel during the process of replenishing liquid into the atomizer 1 through the liquid replenishment assembly 2, and leakage of atomized liquid can be avoided during the replenishment process.

[0035] Since both the atomizer 1 and the refill kit 2 can be detachably connected to the battery kit 3, the lifespan of the electronic atomizing device can be extended by replacing the atomizer 1 when any parts in the atomizer 1 are damaged. Furthermore, the lifespan of the electronic atomizing device can be extended or the user's different taste preferences can be met by disassembling and replacing the refill kit 2 when the atomized liquid in the refill kit 2 is depleted or when it is necessary to change the flavor of the atomized liquid. This improves the user experience and reduces the operating cost of the electronic atomizing device.

[0036] In some embodiments, please refer to Figure 2 and Figure 3 The battery assembly 3 includes a housing 31, a bracket assembly 32, a battery cell 33, and a control module 34. The bracket assembly 32, the battery cell 33, and the control module 34 are all installed in the housing 31. The bracket assembly 32 can be fixedly connected to the housing 31 by a snap fastener. The battery cell 33 and the control module 34 are both installed on the bracket assembly 32. The control module 34 includes a circuit board 341 and electronic components installed on the circuit board 341. The control module 34 is located between the atomizer 1 and the liquid replenishment assembly 2 in the extension direction of the atomization channel 13. The battery cell 33 is located on the side of the control module 34 away from the atomizer 1 in the extension direction of the atomization channel 13, so as to facilitate the electrical connection of the control module 34 with the battery cell 33 and the atomizer 1 respectively. The battery cell 33 can be a cylindrical battery cell or a square battery cell. The battery cell 33 is arranged in the extension direction of the atomization channel 13. The replenishment bottle 21 in the replenishment component 2 extends in the extension direction of the atomization channel 13. The battery cell 33 and the replenishment component 2 are arranged in a plane perpendicular to the extension direction of the atomization channel 13. This helps to improve the compactness of the overall structure of the electronic atomization device and realize the miniaturization design of the electronic atomization device.

[0037] In some embodiments, please continue to refer to Figures 2 to 6The bracket assembly 32 has a receiving groove 322 located opposite to the battery cell 33 or opposite to the liquid replenishment assembly 2 in the extension direction of the atomization channel 13. The opening of the receiving groove 322 is located opposite to the liquid replenishment assembly 2. The outer shell 31 has an opening communicating with the opening of the receiving groove 322. The atomizer 1 can be installed in the receiving groove 322 in the extension direction of the atomization channel 13. The atomizer 1 can be detachably connected to the battery assembly 3 by magnetic attraction or by snap-fit ​​connection.

[0038] In one embodiment, one of the sidewalls of the receiving groove 322 and the sidewall of the atomizer 1 is provided with a buckle, and the other is provided with a slot. The buckle and the slot cooperate to realize the installation of the atomizer 1 in the receiving groove 322, that is, to realize the detachable connection between the atomizer 1 and the battery assembly 3.

[0039] In another embodiment, magnetic components are provided on the bottom wall of the receiving groove 322 and on the atomizer 1. The atomizer 1 can be installed in the receiving groove 322 by the attraction of the two magnetic components, that is, the atomizer 1 and the battery assembly 3 can be detachably connected.

[0040] In some embodiments, please refer to Figure 4 and Figure 5 The control module 34 has a connecting electrode 343 extending into the receiving groove 322 in the direction of the atomization channel 13. The corresponding atomizer 1 has a contact electrode 18 that is electrically connected to the atomizing core 14. After the atomizer 1 is installed in the receiving groove 322, the connecting electrode 343 can make elastic contact with the contact electrode 18, so as to realize the electrical connection between the control module 34 and the atomizing core 14.

[0041] In some embodiments, the control module 34 has an airflow sensor 342 electrically connected to the circuit board 341. The bottom wall of the receiving groove 322 is provided with a trigger hole 323 that is fluidly connected to the trigger end of the airflow sensor 342. Correspondingly, the atomizer 1 has a mouthpiece 11 and an airflow channel 12 that is fluidly connected to the mouthpiece 11. After the atomizer 1 is installed in the receiving groove 322, the airflow channel 12 is connected to the trigger hole 323. The hole wall of the trigger hole 323 is located in the airflow channel 12 and is sealed to the channel wall of the airflow channel 12, so as to achieve a sealed connection between the airflow channel 12 and the trigger hole 323. When the user inhales by covering the mouthpiece 11 with his / her lips, a negative pressure can be generated at the trigger end of the airflow sensor 342 through the airflow channel 12 and the trigger hole 323. After the airflow sensor 342 is triggered, the control module 34 can control the heating of the atomizing core 14.

[0042] The structure described above, which includes a receiving groove 322 in the battery assembly 3 and atomizer 1 installed in the receiving groove 322, can reduce the probability of external dust contacting the connecting electrode 343 and entering the airflow channel 12, thus helping to ensure the normal use of the electronic atomization device.

[0043] In some embodiments, please refer to Figure 2 and Figure 3 The support assembly 32 includes a first support 321 and a second support 324 arranged in the extension direction of the atomizing channel 13. The first support 321 and the second support 324 are connected by snaps or screws, and the receiving groove 322 is formed by the first support 321.

[0044] Please refer to Figure 6 During the assembly of battery assembly 3, the first bracket 321 is first installed inside the housing 31, and the first bracket 321 is connected to the housing 31 by a snap-fit. Then, the control module 34, battery cell 33, and other parts such as the seal 35 (described later) are integrated and installed on the second bracket 324. The second bracket 324 is then installed inside the housing 31 and connected to the first bracket 321 by a snap-fit ​​or screw, thus completing the assembly of the entire battery assembly 3. In the electronic atomizing device, the atomizer 1 can be inserted into the receiving slot 322 of the first bracket 321 after the battery assembly 3 is assembled. The liquid replenishment component 2 is installed on the side or end of the battery assembly 3 facing away from the atomizer 1.

[0045] In some embodiments, please refer to Figure 2 and Figure 3 The connecting hole 325 in the battery assembly 3 for connecting the liquid inlet hole 16 and the liquid outlet hole 23 can be provided on the second bracket 324. The hole wall of the connecting hole 325 can extend into the receiving groove 322 in the extension direction of the atomizing channel 13. At least a portion of the first hole segment 326 can be located in the receiving groove 322 to facilitate the sealing and cooperation between the hole wall of the first hole segment 326 and the hole wall of the liquid inlet hole 16 in the atomizer 1.

[0046] In one embodiment, the wall of the first orifice 326 and the wall of the inlet hole 16 are sealed by an end face. The first orifice 326 has a sealing surface that seals with the wall of the inlet hole 16, and this sealing surface is perpendicular to the extension direction of the connecting hole 325. At least one of the walls of the first orifice 326 and the inlet hole 16 may be made of rubber material. The wall of the first orifice 326 abuts against the wall of the inlet hole 16 in the extension direction of the connecting hole 325 to achieve a seal between the wall of the first orifice 326 and the wall of the inlet hole 16.

[0047] In some embodiments, the wall of the first orifice 326 and the wall of the inlet hole 16 are circumferentially sealed. The wall of the first orifice 326 is inserted into the inlet hole 16, and the outer side of the wall of the first orifice 326 is sealed with the inner side of the wall of the inlet hole 16. The wall of the first orifice 326 and the inlet hole 16 are press-fitted to achieve a seal. Alternatively, a sealing element 35 is fitted on the outer side of the wall of the first orifice 326, and the wall of the first orifice 326 is sealed with the wall of the inlet hole 16 through the sealing element 35.

[0048] In other embodiments, the wall of the inlet hole 16 may be inserted into the first hole section 326, and the wall of the inlet hole 16 may be press-fitted with the first hole section 326 to achieve a seal, or the sealing member 35 may be fitted on the outer side of the wall of the inlet hole 16 to achieve a seal between the wall of the inlet hole 16 and the wall of the first hole section 326.

[0049] Compared to end-face sealing, this method of sealing the periphery of the first hole section 326 hole wall and the inlet hole 16 hole wall increases the sealing area between the first hole section 326 hole wall and the inlet hole 16 hole wall, thereby improving the sealing performance of the battery assembly 3 and the atomizer 1 at the inlet hole 16.

[0050] In some embodiments, please continue to refer to Figure 2 and Figure 3 The inlet hole 16 has a large-diameter hole section 161 and a small-diameter hole section 162 connected in the extension direction of the connecting hole 325. The diameter of the large-diameter hole section 161 is larger than the diameter of the small-diameter hole section 162. The large-diameter hole section 161 is located on the side of the small-diameter hole section 162 facing the connecting hole 325 in the extension direction of the connecting hole 325. The hole wall of the first hole section 326 is located inside the large-diameter hole section 161, and the outer side of the hole wall of the first hole section 326 is sealed to the inner side of the hole wall of the large-diameter hole section 161.

[0051] The wall of the small-diameter orifice 162 extends into the large-diameter orifice 161 in the direction of the connecting hole 325. The outer diameter of the small-diameter orifice 162 is smaller than the inner diameter of the first orifice 326. When the atomizer 1 is connected to the battery assembly 3, the wall of the small-diameter orifice 162 can be inserted into the first orifice 326, and the outer surface of the wall of the small-diameter orifice 162 is sealed to the inner surface of the wall of the first orifice 326. This sealing can be achieved by the sealing element 35 or by an interference fit. The wall of the first hole segment 326 is located between the wall of the large-diameter hole segment 161 and the wall of the small-diameter hole segment 162 in the plane perpendicular to the extension direction of the connecting hole 325. The wall of the first hole segment 326 is sealed to the inner side of the wall of the large-diameter hole segment 161 and the outer side of the wall of the small-diameter hole segment 162, respectively. In this way, the atomizer 1 and the battery assembly 3 achieve double circumferential sealing at the liquid inlet hole 16, which can further improve the sealing performance of the battery assembly 3 and the atomizer 1 at the liquid inlet hole 16.

[0052] In other embodiments, the wall of the liquid inlet 16 is inserted into the first hole segment 326. Both the large-diameter hole segment 161 and the small-diameter hole segment 162 are located on the first hole segment 326. The large-diameter hole segment 161 is located on the side of the small-diameter hole segment 162 facing the liquid inlet 16 in the extension direction of the connecting hole 325. When the atomizer 1 is connected to the battery assembly 3, the wall of the liquid inlet 16 is located between the wall of the large-diameter hole segment 161 and the wall of the small-diameter hole segment 162 in the plane perpendicular to the extension direction of the connecting hole 325. The wall of the liquid inlet 16 is sealed to the inner side of the wall of the large-diameter hole segment 161 and the outer side of the wall of the small-diameter hole segment 162 to achieve a double circumferential seal between the atomizer 1 and the battery assembly 3 at the liquid inlet 16.

[0053] Furthermore, to improve the sealing performance between the wall of the small-diameter orifice 162 and the wall of the first orifice 326 or the wall of the inlet orifice 16, the small-diameter orifice 162 within the large-diameter orifice 161 is 1.5 mm in the extending direction of the connecting hole 325. This ensures the sealing area of ​​the small-diameter orifice 162 and prevents leakage at the inlet orifice 16. Of course, in other embodiments, the size of the small-diameter orifice 162 within the large-diameter orifice 161 can also be 1 mm, 2 mm, or other sizes between 1 mm and 2 mm.

[0054] In some embodiments where the inlet hole 16 and the first hole section 326 are double-circumferentially sealed, the inlet hole 16 has a large-diameter hole section 161 and a small-diameter hole section 162 connected in the extending direction of the connecting hole 325. The battery assembly 3 includes a sealing member 35, which has a first part 351 and a second part 352 connected to each other. The first part 351 is fitted onto the outside of the hole wall of the first hole section 326. When the atomizer 1 is connected to the battery assembly 3, the first part 351 is located between the hole wall of the first hole section 326 and the hole wall of the large-diameter hole section 161 to achieve... The first hole section 326 is sealed to the hole wall of the large-diameter hole section 161. When the atomizer 1 is connected to the battery assembly 3, the second part 352 is located inside the first hole section 326 and between the hole wall of the first hole section 326 and the hole wall of the small-diameter hole section 162. Thus, the sealing element 35 is used to achieve a seal between the hole wall of the first hole section 326 and the hole wall of the small-diameter hole section 162. In this way, the double circumferential seal between the hole wall of the liquid inlet hole 16 and the hole wall of the first hole section 326 is achieved by the same sealing element 35, which can reduce the number of parts in the electronic atomizing device and facilitate the assembly of the electronic atomizing device.

[0055] In other embodiments, both the large-diameter orifice 161 and the small-diameter orifice 162 are located on the first orifice 326. The seal 35 may also be located in the atomizer 1. The first part 351 of the seal 35 is fitted outside the wall of the liquid inlet 16, and the second part 352 of the seal 35 is located inside the liquid inlet 16. The first part 351 of the seal 35 achieves the sealing between the wall of the liquid inlet 16 and the wall of the large-diameter orifice 161, and the second part 352 achieves the sealing between the wall of the liquid inlet 16 and the wall of the small-diameter orifice 162.

[0056] In other embodiments, the atomizer 1 and the battery assembly 3 are sealed at the liquid inlet 16 by two seals. For example, the two seals can be respectively fitted onto the outer side of the wall of the small diameter section 162 and the outer side of the wall of the first section 326, so that the wall of the first section 326 can be sealed with the wall of the large diameter section 161 and the wall of the small diameter section 162 by the two seals 35.

[0057] In some embodiments where the atomizer 1 and the battery assembly 3 achieve a double circumferential seal at the liquid inlet 16 via the same seal 35, please refer to Figure 2 and Figure 3 The seal 35 also has a mounting portion 356 connected to the first portion 351. This mounting portion 356 is press-fitted and fixed between the first bracket 321 and the second bracket 324 in the extending direction of the connecting hole 325. This achieves the installation and fixation of the seal 35 in the battery assembly 3, preventing the seal 35 from separating from the orifice wall of the first orifice segment 326 during atomizer 1 disassembly. Alternatively, in other embodiments, the seal 35 can be integrally formed with the second bracket 324, thus preventing the seal 35 from separating from the orifice wall of the first orifice segment 326 during atomizer 1 disassembly.

[0058] In some embodiments, for seal 35, please refer to Figure 2 , Figure 3 and Figure 5The sealing element 35 is made of rubber material with good elastic deformation ability. The second part 352 of the sealing element 35 has multiple valves 353. The connecting hole 325 is a circular hole. The multiple valves 353 are arranged around the central axis of the connecting hole 325. When the atomizer 1 and the battery assembly 3 are in the disassembled state, without the action of external force, all valves 353 extend towards the central axis of the connecting hole 325. All valves 353 align to block the first hole segment 326, which can reduce the probability of the atomized liquid flowing out from the connecting hole 325. When the atomizer 1 and the battery assembly 3 are in the connected state, all valves 353 are pressed by the hole wall of the small diameter hole segment 162 between the hole wall of the first hole segment 326 and the hole wall of the small diameter hole segment 162 to achieve the sealing between the hole wall of the first hole segment 326 and the hole wall of the small diameter hole segment 162. The sealing element 35 with this structure can not only improve the sealing performance of the liquid inlet 16 during normal use of the electronic atomizing device, but also block the connecting hole 325 during the disassembly of the atomizer 1, so as to reduce the probability of the atomized liquid flowing out from the connecting hole 325.

[0059] Of course, in other embodiments, the second part 352 of the sealing member 35 can be set to always fit against the inner side of the hole wall of the first hole segment 326. In addition, a liquid outlet valve that can be manually or electrically controlled is provided on the liquid replenishment assembly 2. The liquid outlet valve can be opened when the atomizer 1 and the battery assembly 3 are connected to replenish the atomizer 1 through the liquid replenishment assembly 2; the liquid outlet valve can be closed when the atomizer 1 and the battery assembly 3 are disassembled to reduce the probability of the atomized liquid flowing out from the connecting hole 325 when the atomizer 1 is disassembled.

[0060] In some embodiments where the second portion 352 of the seal 35 includes a plurality of valves 353, please refer to Figure 2 , Figure 3 and Figure 5 Each valve 353 is configured to have a suspension end 355 and a connection end 354 connected to the first part 351 in the radial direction of the connecting hole 325. When the atomizer 1 and the battery assembly 3 are in a disassembled state, the suspension end 355 is located on the side of the connection end 354 facing the connecting hole 325 in the extension direction of the connecting hole 325. For example, the end faces of multiple valves 353 facing away from the connecting hole 325 are coplanar and form a conical surface or an inwardly concave curved surface. This can improve the sealing ability of the second part 352 to the connecting hole 325, further reduce the probability of the atomized liquid flowing out of the connecting hole 325, and even prevent the atomized liquid from flowing out of the connecting hole 325.

[0061] In other embodiments, if the atomizing liquid cannot flow out of the connecting hole 325 when the atomizer 1 and the battery assembly 3 are disassembled, the end faces of the multiple valves 353 facing away from the connecting hole 325 can also be coplanar and perpendicular to the extending direction of the connecting hole 325 without the action of external force.

[0062] In some embodiments, please refer to Figures 2 to 5 The atomizer 1 has an air inlet 17 that communicates with the atomization channel 13. The battery assembly 3 has an air inlet channel 358 and an air outlet 357. The air outlet 357 is located on the bottom wall of the receiving groove 322 and communicates with the air inlet channel 358. The outer shell 31 has an air hole that communicates with the air inlet channel 358. External gas can enter the air inlet channel 358 through the air hole and enter the atomizer 1 in the receiving groove 322 along the air inlet channel 358 and the air outlet 357.

[0063] The intake channel 358 is formed by the first bracket 321 and the second bracket 324. The intake channel 358 is arranged around the connecting hole 325 on the second bracket 324. The sealing member 35 is sealed between the first bracket 321 and the second bracket 324. The sealing member 35 has a through hole arranged in the extending direction of the connecting hole 325. The through hole communicates with the intake channel 358 to form an air outlet 357. When the atomizer 1 and the battery assembly 3 are connected, part of the wall of the air inlet 17 on the atomizer 1 is inserted into the air outlet 357 in the extension direction of the connecting hole 325, and the outer side of the wall of the air inlet 17 is sealed to the inner side of the wall of the air outlet 357. Alternatively, the wall of the air outlet 357 can be inserted into the air inlet 17 in the extension direction of the connecting hole 325, and the outer side of the wall of the air outlet 357 is sealed to the inner side of the wall of the air inlet 17. In this way, the sealing of the atomizer 1 and the battery assembly 3 at the air inlet 17 can be achieved by sealing the outer peripheral surface. Compared with the conventional end face sealing method, the sealing performance of the atomizer 1 and the battery assembly 3 at the air inlet 17 can be improved.

[0064] Of course, in other embodiments, the end face of the air inlet 17 wall in the vertical connecting hole 325 extension direction can be sealed and fitted with the end face of the air outlet 357 wall, so as to achieve a sealed fit between the atomizer 1 and the battery assembly 3 at the air inlet 17.

[0065] In some embodiments, to further improve the sealing performance of the atomizer 1 and the battery assembly 3 at the air inlet 17, the structure of the air inlet 17 or the air outlet 357 can be similar to the structure of the liquid inlet 16. The air inlet 17 or the air outlet 357 includes a large-diameter section and a small-diameter section. The wall of the small-diameter section extends into the large-diameter section. One of the walls of the air outlet 357 and the air inlet 17 is located between the walls of the large-diameter section and the small-diameter section of the other in a plane perpendicular to the extension direction of the connecting hole 325, and is sealed to the walls of the large-diameter section and the small-diameter section respectively. Thus, a double circumferential seal of the atomizer 1 and the battery assembly 3 is achieved at the air inlet 17.

[0066] In some embodiments, please continue to refer to Figure 2 and Figure 3For the replenishing component 2, the outlet hole 23 of the replenishing component 2 is sealed to the second hole segment 327 of the connecting hole 325 in the battery component 3. When the replenishing component 2 and the battery component 3 are connected, the hole wall of the outlet hole 23 can be set to be located inside the second hole segment 327, and the outer side of the hole wall of the outlet hole 23 is sealed to the inner side of the hole wall of the second hole segment 327. Alternatively, the hole wall of the second hole segment 327 can be set to be located inside the outlet hole 23, and the outer side of the hole wall of the second hole segment 327 is sealed to the inner side of the hole wall of the outlet hole 23. In this way, a circumferential seal is achieved between the replenishing component 2 and the battery component 3 at the outlet hole 23.

[0067] In some embodiments, a sealing fit between the wall of the outlet hole 23 and the wall of the second orifice segment 327 can be achieved by installing a sealing ring 24 on the outer surface of the wall of the outlet hole 23 or the outer surface of the wall of the second orifice segment 327. In other embodiments, an interference fit between the wall of the outlet hole 23 and the wall of the second orifice segment 327 can also be used to achieve a sealing fit.

[0068] In some embodiments, the structure of the liquid outlet 23 or the second hole segment 327 can be similar to that of the liquid inlet 16. The liquid outlet 23 or the second hole segment 327 includes a large-diameter hole segment and a small-diameter hole segment. The hole wall of the small-diameter hole segment extends into the large-diameter hole segment. One of the hole walls of the liquid outlet 23 and the second hole segment 327 is located between the hole walls of the large-diameter hole segment and the small-diameter hole segment of the other in a plane perpendicular to the extension direction of the connecting hole 325, and is sealed with the hole walls of the large-diameter hole segment and the small-diameter hole segment respectively. In this way, the liquid replenishment component 2 and the battery component 3 are sealed on both sides at the liquid outlet 23.

[0069] In this embodiment, the liquid replenishment component 2 and the battery component 3 are detachably connected. For some embodiments, please refer to... Figure 2 and Figure 3 In the replenishment component 2, a guide groove is provided on the side wall of the replenishment bottle 21 extending in the direction of the connecting hole 325. The corresponding battery component 3 has a guide protrusion 311 that cooperates with the guide groove on the outer shell 31 or the second bracket 324. During the installation of the replenishment component 2 and the battery component 3, the guide protrusion 311 is inserted into the guide groove. The guide protrusion 311 can provide guidance for the installation of the replenishment component 2 to ensure that the liquid outlet 23 of the replenishment component 2 is inserted into the second hole segment 327 of the connecting hole 325.

[0070] In some embodiments, the fluid replenishment component 2 can be detachably connected to the battery component 3 via magnetic attraction or snap-fit ​​connection. Magnetic components can be provided on both the fluid replenishment bottle 21 in the fluid replenishment component 2 and the second support 324 in the battery component 3. The two magnetic components attract each other in the direction extending from the connecting hole 325 to achieve a detachable connection between the fluid replenishment component 2 and the battery component 3. Alternatively, a slot 328 can be provided on one of the fluid replenishment bottle 21 in the fluid replenishment component 2 and a protrusion 22 on the other. After the fluid replenishment component 2 is installed in place with the battery component 3 under the guidance of the guide protrusion 311, the protrusion 22 enters the slot 328, thereby achieving a detachable connection between the fluid replenishment component 2 and the battery component 3 via a snap-fit ​​connection.
