DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0036] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] At present, for the sake of convenience, many aerosol generating devices are set as disposable products and are discarded as a whole after use. However, when designing the battery cell, in order to ensure the reliable electrical connection between the battery cell and the atomizer, the battery cell is generally assembled in a non-detachable manner, such as connecting the battery cell and the atomizer by welding a wire, and then wrapping the wire and the pins of the battery cell to the shell by wrapping tape. This results in that when the aerosol generating device is discarded, the battery cell cannot be taken out in time, causing the battery cell to pollute the environment due to not being recycled for a long time, and may even cause an explosion.

[0039] In order to solve the above technical problems, the embodiment of the present application provides a power supply unit 1 and an aerosol generating device, which realizes the electrical connection between the battery cell 110 and the atomizer 2 by setting an electrical connection seat 300, and the battery cell 110 and the electrical connection seat 300 are detachably connected, so that the battery cell 110 and the electrical connection seat 300 can be quickly and conveniently separated. At the same time, the battery cover 120 and the shell assembly 200 are detachably connected through the cooperation of the protrusion 260 and the groove 124, so as to facilitate the removal of the battery cell 110 from the shell assembly 200, facilitate the recycling of the battery cell 110, and reduce environmental pollution.

[0040] See also Figures 1 to 3 The aerosol generating device provided in the embodiment of the present application is now described. The aerosol generating device comprises a power supply unit 1 and an atomizer 2, wherein the power supply unit 1 is electrically connected to the atomizer 2, the power supply unit 1 is used to supply power to the atomizer 2, and the atomizer 2 is used to atomize the atomizing medium into aerosol particles and deliver the generated aerosol particles to the oral cavity of the smoker.

[0041] In one embodiment, see Figure 3 The aerosol generating device further includes an electric control component 3 , which is electrically connected to the power supply unit 1 , and the electric control component 3 is electrically connected to the atomizer 2 , and the power supply unit 1 supplies power to the atomizer 2 through the electric control component 3 .

[0042] See also Figures 2 to 8 , the power supply unit 1 provided in the embodiment of the present application is now described. The power supply unit 1 is used to supply power to the atomizer 2, and the power supply unit 1 includes a housing assembly 200, an electrical connection seat 300 and a battery assembly 100; the housing assembly 200 has a battery compartment 230 with a bottom opening; the electrical connection seat 300 is fixed in the housing assembly 200 and electrically connected to the atomizer 2; the battery assembly 100 includes a battery cell 110 and a battery cover 120, the battery cell 110 can be accommodated in the battery compartment 230, and the battery cell 110 is electrically connected to the electrical connection seat 300 and is detachable; one of the housing assembly 200 and the battery cover 120 is formed with a protrusion 260, and the other of the housing assembly 200 and the battery cover 120 is formed with a groove 124; the protrusion 260 cooperates with the groove 124 to achieve a detachable connection between the battery cover 120 and the housing assembly 200.

[0043] Among them, the setting of the protrusion 260 and the groove 124 can limit the battery cover 120 circumferentially and axially, so that the battery cover 120 and the shell assembly 200 are firmly connected, reducing the possibility that the battery cover 120 is accidentally touched by the user and caused to be accidentally removed.

[0044] It should be noted that axial and circumferential limiting of the battery cover 120 refers to limiting the battery cover 120 along the circumference and axial direction, and may also be limiting the battery cover 120 along the circumference and axial direction of the battery compartment 230 or the battery cell 110 .

[0045] The power supply unit 1 in the embodiment of the present application realizes the electrical connection between the battery cell 110 and the atomizer 2 by providing the electrical connection seat 300, and the battery cell 110 and the electrical connection seat 300 are designed to be detachably electrically connected, so as to facilitate the separation of the battery cell 110 and the electrical connection seat 300. At the same time, the battery cover 120 and the housing assembly 200 are detachably connected by the cooperation of the protrusion 260 and the groove 124, which can not only firmly fix the battery cover 120 on the housing assembly 200, but also facilitate the removal of the battery cover 120 from the housing assembly 200, thereby making it easy to take out the battery cell 110, which is beneficial to the recycling of the battery cell 110 and reduces environmental pollution.

[0046] In one embodiment, see Figures 6 to 8 The battery cover 120 and the housing assembly 200 are connected by rotating the buckle, and when the battery cover 120 and the housing assembly 200 are rotated and connected in place, the protrusion 260 is inserted into the groove 124. The rotating buckle can form a circumferential limit between the battery cover 120 and the housing assembly 200, and the protrusion 260 and the groove 124 can not only form a circumferential limit and an axial limit between the battery cover 120 and the housing assembly 200, but also strengthen the connection strength between the battery cover 120 and the housing assembly 200.

[0047] In this embodiment, the protrusion 260 and the groove 124 are snap-fitted along the circumference of the battery cover 120. It can be understood that in other embodiments of the present application, the battery cover 120 and the housing assembly 200 can also slide along the axial direction of the battery cover 120 so that the protrusion 260 and the groove 124 are snap-fitted, which is not the only limitation here.

[0048] In one embodiment, see Figures 6 to 8 A protrusion 125 is convexly provided on the outer peripheral wall of the battery cover 120, and a limiting groove 250 is formed on the inner peripheral wall of the shell assembly 200. The limiting groove 250 includes an introduction portion 251 and a clamping portion 252. The introduction portion 251 extends along the axial direction of the battery compartment 230 and passes through the bottom end of the shell assembly 200. The clamping portion 252 extends from the introduction portion 251 along the circumferential direction of the battery compartment 230. The introduction portion 251 is used to introduce the protrusion 125 into the clamping portion 252, and the clamping portion 252 is used to limit the protrusion 125.

[0049] When assembling the battery cover 120, the battery cover 120 is inserted into the battery compartment 230 along the axial direction, and the protrusion 125 is inserted into the introduction portion 251 along the axial direction. When the protrusion 125 is inserted into the introduction portion 251 to the top, the battery cover 120 is rotated so that the protrusion 125 is screwed into the clamping portion 252 from the introduction portion 251, so that the protrusion 125 is limited in the clamping portion 252, thereby forming the clamping connection between the battery cover 120 and the shell assembly 200. At this time, the protrusion 260 is clamped into the groove 124, further strengthening the connection strength between the battery cover 120 and the shell assembly 200.

[0050] Optionally, the inner peripheral wall of the housing assembly 200 is formed with two circumferentially spaced limiting grooves 250, and the outer peripheral wall of the battery cover 120 is formed with two circumferentially spaced protrusions 125, and the two protrusions 125 are respectively correspondingly engaged with the two limiting grooves 250. It can be understood that in other embodiments of the present application, the number of the protrusions 125 and the limiting grooves 250 can also be one, three, or more than three, which is not limited here.

[0051] In one embodiment, see Figures 6 to 8 , the protrusion 260 is protruded from the clamping portion 252 toward the inner wall of the battery compartment 230, and the groove 124 is formed on the protrusion 125. The above arrangement ensures that the protrusion 260 does not protrude from the inner wall of the battery compartment 230, that is, the arrangement of the protrusion 260 does not interfere with the rotational movement of the battery cover 120. It can be understood that in other embodiments of the present application, the protrusion 260 can be formed on the inner wall of the battery compartment 230, and the groove 124 is formed on the outer wall of the battery cover 120. In addition, in other embodiments, the limiting groove 250 can also be formed on the battery cover 120, and the protrusion 125 can be formed in the shell assembly 200, which is not limited here.

[0052] In one embodiment, see Figure 7 , along the lateral direction of the battery compartment 230, the depth of the recess of the clamping portion 252 is greater than the depth of the recess of the introduction portion 251, the protrusion 260 is formed on the inner wall of the clamping portion 252, and the protrusion 260 does not protrude from the inner wall of the battery compartment 230. The above arrangement not only makes the protrusion 260 high enough so that the clamping of the protrusion 260 and the groove 124 can ensure the assembly stability of the battery cover 120, but also makes the arrangement of the protrusion 260 not affect the rotational movement of the battery cover 120.

[0053] In one embodiment, see Figure 7 The introduction portion 251 includes an ejection surface 2511, which is the inner wall surface of the introduction portion 251 axially away from the opening end surface of the battery compartment 230. The ejection surface 2511 extends obliquely from one end away from the clamping portion 252 along a direction away from the opening end surface to the clamping portion 252.

[0054] It should be noted that the open end face of the battery compartment 230 refers to the end face of the bottom opening of the battery compartment 230 facing outward.

[0055] In this embodiment, the ejection surface 2511 is extended obliquely in a direction away from the opening end surface to the clamping portion 252, so that when the protrusion 125 is inserted into the introduction portion 251 and abuts against the ejection surface 2511, the ejection surface 2511 has a guiding effect on the protrusion 125, so as to guide the protrusion 125 to be clamped into the clamping portion 252. On the contrary, when the battery cover 120 is rotated in the reverse direction, when the protrusion 125 rotates from the clamping portion 252 to the introduction portion 251, the ejection surface 2511 has a function of ejecting the protrusion 125 toward the opening end surface, so that the protrusion 125 is easily removed from the introduction portion 251.

[0056] In one embodiment, see Figure 6 and Figure 8 The outer end surface of the battery cover 120 facing away from the battery core 110 is concavely provided with a rotation groove 1211. In practical applications, a tool can be inserted into the rotation groove 1211 to rotate the battery cover 120, so that the disassembly and assembly of the battery cover 120 is convenient and labor-saving.

[0057] For details, please refer to Figure 8 The rotating groove 1211 can be designed to be long and narrow, so that a coin, a game coin or a simple tool can be inserted into the rotating groove 1211 to rotate the battery cover 120 without a specific tool. In other embodiments, the rotating groove 1211 can also be designed to be a cross, a plum blossom or other shapes to match different disassembly tools, which is not limited here.

[0058] In one embodiment, see Figure 1 An arrow mark 290 is formed on the bottom surface of the shell assembly 200 corresponding to the position of the battery cover 120. When the battery cover 120 is rotated until the rotation groove 1211 is aligned with the arrow mark 290, it means that the protrusion 125 is rotated from the clamping portion 252 to the introduction portion 251. At this time, you only need to take out the battery cover 120 axially outward.

[0059] In one embodiment, see Figures 9 to 12 The battery assembly 100 also includes an adapter 140, which is fixedly connected to the side of the battery cell 110 away from the electrical connection seat 300; the battery cover 120 and the adapter 140 are detachably connected, and when the battery cover 120 is rotated and disassembled, the adapter 140 and the battery cell 110 can be taken out together, that is, when disassembling, the battery cover 120, the adapter 140 and the battery cell 110 can be disassembled at one time, which is convenient for disassembly and assembly.

[0060] In one embodiment, see Fig.10 and Fig.11The battery cover 120 is rotatably sleeved outside the adapter seat 140, the inner wall of the battery cover 120 is provided with a first abutting portion 123, and the outer wall of the adapter seat 140 is provided with a second abutting portion 143, and the first abutting portion 123 is located on the side of the second abutting portion 143 facing the battery cell 110; the first abutting portion 123 abuts against the second abutting portion 143 after withdrawing a preset distance away from the electrical connection seat 300.

[0061] In addition, the first abutting portion 123 abuts against the second abutting portion 143 after withdrawing from the electrical connection seat 300 by a preset distance, which means that after the battery cover 120 and the adapter seat 140 are assembled, the first abutting portion 123 and the second abutting portion 143 are arranged at intervals along the axial direction of the battery cell 110, and when the battery cover 120 withdraws from the electrical connection seat 300 by a preset distance, the first abutting portion 123 abuts against the second abutting portion 143, so that the protective seat 130 and the battery cell 110 can be taken out together through the battery cover 120. Among them, since the battery cover 120 needs to be rotated when disassembling the battery cover 120, in order to prevent the rotation of the battery cover 120 from driving the battery cell 110 to rotate, it is designed that after the battery cover 120 is rotated and taken out by a preset distance, the battery cover 120 is separated from the shell assembly 200 and then the battery cell 110 is taken out through the battery cover 120.

[0062] Optionally, the adapter 140 may be fixed to the battery cell 110 by gluing, for example, by gluing with adhesive or double-sided tape. Alternatively, the adapter 140 may also be fixed to the battery cell 110 by interference fit.

[0063] In one embodiment, see Figures 10 to 12 The adapter 140 includes a top plate 141 attached to the battery cell 110 and a first side plate 142 formed on the side of the top plate 141 away from the battery cell 110. The first side plate 142 is formed with a first through slot 144 extending along the axial direction of the battery cell 110. The second abutment 143 is an annular plate formed on the outer side wall of the first side plate 142. The provision of the first through slot 144 can improve the elasticity of the first side plate 142, so that when the first side plate 142 is inserted into the battery cover 120 during assembly, the second abutment 143 can overcome the first abutment 123 and snap into the side of the first abutment 123 away from the electrical connection seat 300.

[0064] Also, see Fig.12 Due to the setting of the first through groove 144, the first side plate 142 is divided into a plurality of sections, and the top plate 141 is formed with an arc groove 146 corresponding to the position of each section. The setting of the arc groove 146 can increase the elasticity of each section to facilitate the assembly of the battery cover 120 and the adapter 140.

[0065] In one embodiment, see Fig.10 and Fig.11The battery cover 120 includes a bottom plate 121 and a second side plate 122 formed on the side of the bottom plate 121 facing the electrical connection seat 300. The second side plate 122 is formed with a protrusion 125. The second side plate 122 can be inserted into the battery compartment 230 and connected to the housing assembly 200. A first abutting portion 123 is also formed on the inner side wall of the second side plate 122. The second side plate 122 is sleeved outside the first side plate 142. The first abutting portion 123 and the second abutting portion 143 can abut against each other.

[0066] See also Figure 6 and Figure 7 The housing assembly 200 is formed with a countersunk hole 240 on the outer end surface corresponding to the battery compartment 230, and the bottom plate 121 is received and limited in the countersunk hole 240. The rotation groove 1211 is formed on the bottom plate 121.

[0067] In one embodiment, see Figure 6 A first pressure relief hole 145 is formed at the center of the top plate 141 where the adapter 140 and the battery cell 110 are attached, and a second pressure relief hole 1212 is formed on the bottom plate 121 where the battery cover 120 and the top plate 141 are opposite. Figure 6 The battery cover 120 and the adapter 140 are mutually sleeved, so that the battery cover 120 and the adapter 140 enclose a cavity. The first pressure relief hole 145 and the second pressure relief hole 1212 are arranged so that when the battery cell 110 explodes, pressure can be released through the first pressure relief hole 145 and the second pressure relief hole 1212 to avoid excessive energy accumulation in the battery cell 110 and produce a huge explosion.

[0068] In one embodiment, see Figure 3 and Figure 4 The battery cell 110 has two pins 111 , and the electrical connection seat 300 is formed with two sockets 313 . The two pins 111 are respectively plugged and matched with the two sockets 313 and are detachable. After the pins 111 are inserted into the sockets 313 , they are electrically connected to the electrical connection seat 300 .

[0069] The battery cell 110 has two pins 111 on the same side, which are a positive pin 111 and a negative pin 111. When the two pins 111 of the battery cell 110 are respectively inserted into the two jacks 313 of the electrical connection socket 300 and are electrically connected to the electrical connection socket 300, the battery cell 110 is electrically connected to the atomizer 2. When the battery cell 110 and the electrical connection socket 300 need to be separated, the battery cell 110 only needs to be pulled out in a direction away from the electrical connection socket 300 to separate the pins 111 of the battery cell 110 from the electrical connection socket 300.

[0070] Specifically, two sockets 313 are formed on the electrical connection socket 300, and the battery cell 110 has two pins 111. The two pins 111 can be inserted into the two sockets 313 and are detachable. When the pins 111 are inserted into the sockets 313, they form an electrical connection with the electrical connection socket 300. That is, the battery cell 110 can be electrically connected and separated from the electrical connection socket 300 by plugging and unplugging the pins 111 and the sockets 313, which is easy to operate.

[0071] In one embodiment, see Figures 2 to 4 , Fig.10 , Fig.11 and Fig.13 The battery assembly 100 further includes a protection seat 130, which is fixedly connected to the battery cell 110. The protection seat 130 is formed with a receiving cavity 131 for receiving two pins 111. The protection seat 130 is fixedly connected to one side of the battery cell 110 having the pins 111. When the battery cell 110 is disassembled, the protection seat 130 is disassembled along with the battery cell 110, and the two pins 111 of the disassembled battery cell 110 can be received in the receiving cavity 131 of the protection seat 130, thereby preventing the battery cell 110 from short-circuiting with other battery cells 110 after being recycled.

[0072] In one embodiment, see Figure 4 , Fig.10 and Fig.11 The electrical connection base 300 includes a plug-in portion 311, which is plugged into the receiving cavity 131, and a plug hole 313 is set through the plug-in portion 311. When the plug-in portion 311 is inserted into the receiving cavity 131, the pin 111 in the receiving cavity 131 is just inserted into the plug hole 313 in the plug-in portion 311, thereby realizing the electrical connection between the pin 111 and the electrical connection base 300.

[0073] In one embodiment, see Figure 3 and Fig.10 , two receiving cavities 131 arranged at intervals are formed in the protective seat 130, and the two pins 111 are respectively received in the two receiving cavities 131, and the electrical connection seat 300 includes two plug-in parts 311 arranged at intervals, and two sockets 313 are respectively arranged through the two plug-in parts 311. The above arrangement can completely isolate the two pins 111 after separation to avoid short circuit. It can be understood that in other embodiments of the present application, only one receiving cavity 131 can be formed in the protective seat 130, and the two pins 111 are accommodated in the receiving cavity 131 at intervals. The electrical connection seat 300 includes a plug-in part 311, and the two sockets 313 are respectively inserted through the plug-in part 311 and arranged at intervals. When the plug-in part 311 is inserted into the receiving cavity 131, the two pins 111 are respectively inserted into the two sockets 313.

[0074] Optionally, the protection seat 130 may be fixed on the battery cell 110 by gluing, for example, by gluing with adhesive or double-sided tape. Alternatively, the protection seat 130 may also be fixed on the battery cell 110 by interference fit.

[0075] In one embodiment, see Figure 4 The electrical connection socket 300 includes a socket body 310 and a conductive member 320 . The insertion hole 313 is formed in the socket body 310 . The conductive member 320 is disposed in the insertion hole 313 . When the pin 111 is inserted into the insertion hole 313 , the conductive member 320 elastically abuts against the pin 111 .

[0076] The seat body 310 is mainly used to realize the assembly of the electrical connection seat 300 in the aerosol generating device. At the same time, the seat body 310 is also used to carry two conductive members 320 and limit the positions of the two conductive members 320 to ensure that when the pin 111 is inserted into the jack 313, the conductive member 320 can elastically abut against the pin 111 to form an electrical connection with the pin 111. In addition, the conductive member 320 is also electrically connected to the electric control component 3. Specifically, the conductive member 320 can be electrically connected to the electric control component 3 by wire welding. When the distance between the conductive member 320 and the electric control component 3 is relatively close, the conductive member 320 can also be directly extended to fit the electric control component 3 for electrical connection.

[0077] In one embodiment, see Fig.14 The conductive member 320 includes an assembly body 322, a conductive sheet 323 and at least two spring sheets 321. The assembly body 322 is assembled in the insertion hole 313. The spring sheets 321 are formed on the assembly body 322 in a circumferential direction. The spring sheets 321 are used to elastically abut against the outer peripheral wall of the pin 111, and the conductive sheet 323 is used to be electrically connected to the electric control component 3. During assembly, the pin 111 of the battery cell 110 is inserted into the insertion hole 313 and between the spring sheets 321, so that the spring sheets 321 elastically abut against different outer peripheral walls of the pin 111, thereby ensuring good contact between the pin 111 and the conductive member 320.

[0078] In one embodiment, see Fig.14 Each spring piece 321 is surrounded to form an insertion space, and the insertion space is set to be larger at both ends and smaller in the middle, that is, each spring piece 321 is set to be an arc-shaped concave setting, thereby improving the abutment reliability between the spring piece 321 and the pin 111.

[0079] In one embodiment, see Fig.14 The assembly body 322 is roughly cylindrical, and a plurality of through slots arranged in sequence along the circumferential direction are formed on the assembly body 322. Each spring piece 321 is formed in each through slot respectively. The assembly body 322, the conductive sheet 323 and the spring piece 321 are connected as a whole.

[0080] In one embodiment, see Figure 4 and Fig.14 The conductive member 320 also includes two abutment sheets 324 respectively connected to the assembly body 322 and arranged opposite to each other. The two abutment sheets 324 are respectively used to abut on the opposite side walls of the seat body 310, and a convex portion is formed on the abutment sheet 324, thereby improving the interference abutment degree between the abutment sheet 324 and the seat body 310, thereby improving the assembly reliability of the conductive member 320 in the seat body 310.

[0081] In one embodiment, see Figure 4 The seat body 310 includes a connecting portion 312 and two plug-in portions 311. The connecting portion 312 is fixed in the aerosol generating device. The two plug-in portions 311 are respectively formed on the same side of the connecting portion 312. The plug hole 313 is sequentially arranged to penetrate the connecting portion 312 and the plug-in portion 311.

[0082] In one embodiment, in order to ensure that when the battery cell 110 and the protective seat 130 are inserted into the battery compartment 230, the protective seat 130 is exactly plugged into the electrical connection seat 300, that is, the plug-in portion 311 is exactly inserted into the receiving cavity 131, and the pin 111 is exactly inserted into the plug-in hole 313, it is necessary to make the plug-in direction of the plug-in portion 311 and the receiving cavity 131, the plug-in direction of the pin 111 and the plug-in hole 313, and the plug-in direction of the protective seat 130 inserted into the battery compartment 230 parallel to each other. For this purpose, please refer to Figure 5 , Fig.13 and Fig.15 A guide structure 400 is formed between the inner wall of the battery compartment 230 and the protective seat 130 for guiding the insertion of the protective seat 130. The guide structure 400 ensures that the battery cell 110 and the protective seat 130 can be accurately assembled by only pushing the battery cell 110 and the protective seat 130 along the insertion direction.

[0083] In one embodiment, see Figure 5 , Fig.13 and Fig.15 The guide structure 400 includes a guide groove 410 formed on the protective seat 130 and a guide block 420 formed on the inner wall of the battery compartment 230. When the protective seat 130 is inserted into the battery compartment 230, the guide block 420 is inserted into the guide groove 410 to guide the insertion of the protective seat 130.

[0084] Optionally, the battery cell 110 is cylindrical, the pin 111 extends along the axial direction of the battery cell 110, and the receiving cavity 131, the plug portion 311, the plug hole 313, the guide groove 410 and the guide block 420 all extend along the axial direction of the battery cell 110, so as to ensure that when the protection seat 130 is inserted into place, the battery cell 110 forms an electrical connection with the electrical connection seat 300. It can be understood that in other embodiments, the battery cell 110 can also be set to a rectangular parallelepiped, an elliptical shape or other regular shapes, which is not limited here.

[0085] In one embodiment, see Figure 5 and Fig.15 The inner wall of the battery compartment 230 is provided with two spaced apart limiting blocks 270, and a positioning column 280 is formed between the two limiting blocks 270, and a positioning hole 314 is formed on the seat body 310. During assembly, the seat body 310 is inserted between the two limiting blocks 270 with interference fit, and the positioning hole 314 is inserted into the positioning column 280, so that the electrical connection seat 300 is installed in the battery compartment 230.

[0086] In one embodiment, see Figure 3 and Figure 5 The housing assembly 200 includes an inner housing 210 and an outer housing 220. Most structures of the electric control assembly 3, the atomizer 2 and the power supply unit 1 are installed in the inner housing 210. The outer housing 220 is covered outside the inner housing 210. The battery cover 120 is connected to the outer housing 220 by a rotating buckle. In addition, it also includes a nozzle 4, which is sleeved on the top outer side of the inner housing 210 and is snap-connected to the outer housing 220.

[0087] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
