Description

Technical Field

[0001] The invention belongs to the technical field of shoe washing, and specifically provides a shoe washing device. Background Art

[0002] In the past, people usually used a brush to clean shoes by hand-brushing, but this method was time-consuming and labor-intensive. The emergence of shoe-washing equipment has freed people's hands and made it easier for people to clean shoes quickly. Existing shoe-washing equipment includes a box, a washing bucket, a pulsator, and a brush assembly. The washing bucket is arranged in the box, the pulsator is arranged at the bottom of the washing bucket, and the brush assembly is arranged on the pulsator. When the pulsator rotates, it drives the brush assembly to rotate so that the shoes are cleaned by the bristles on the brush assembly. As the number of washes increases, the bristles on the brush assembly are easily damaged during the friction with the shoes. Therefore, the brush assembly is usually fixed to the pulsator by screws to facilitate replacement of the brush assembly. However, during the replacement process, the screws need to be unscrewed, the brush assembly removed, and then the new brush assembly is installed on the pulsator by screws. This fixing method is not convenient for replacing the brush assembly.

[0003] Therefore, this area needs a new shoe washing device to solve the above problems. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the brush assembly in the existing shoe washing device is set on the impeller by screws, which makes it inconvenient to replace the brush assembly, the present invention provides a shoe washing device, which includes a box, a washing bucket, a impeller and a brush assembly, the washing bucket is arranged in the box, the impeller is arranged at the bottom of the washing bucket, and the impeller is provided with an opening structure, the brush assembly includes a first body, a second body and bristles, the first body is provided with a accommodating structure, the second body is arranged in the accommodating structure, the bristles are arranged on the first body and / or the second body, and the first body is provided with a first limiting portion. When the brush assembly and the impeller are assembled, the second body is located in the installation position so that the first limiting portion moves to a side away from the second body and thereby allows the first limiting portion to cooperate with the side of the opening structure close to the washing bucket to prevent the brush assembly from being separated from the impeller, and the second body can selectively separate from the first body and thereby allow the first limiting portion to move to a side away from the opening structure so that the first limiting portion is separated from the opening structure.

[0005] With such an arrangement, when the brush assembly and the impeller are assembled, the second body can be separated from the first body, so that the first limiting part can be separated from the opening structure so that the brush assembly can be removed from the impeller; in addition, during the assembly of the brush assembly and the impeller, the second body can be separated from the first body, so that the first limiting part can be moved to the side away from the opening structure, so that the first limiting part can pass through the opening structure during the assembly process; with such a structural arrangement, there is no need to remove and install screws during the process of removing the brush assembly from the impeller or installing it to the impeller, which facilitates the disassembly and replacement of the brush assembly, and after the brush assembly is disassembled, the shoe washing device can be used to wash clothes, making the shoe washing device more functional.

[0006] In the preferred technical solution of the above-mentioned shoe washing equipment, a second limiting portion is provided on the inner side wall of the containing structure, and a third limiting portion is provided on the second body. When the first body and the second body are assembled, the second limiting portion and the third limiting portion cooperate to limit the second body to the installation position.

[0007] By such an arrangement, that is, by providing the second limiting portion and the third limiting portion, the second body can be maintained at the installation position, the structure is simple, and it is easy to implement.

[0008] In the preferred technical solution of the above-mentioned shoe washing device, the second body is a cylinder, there is a gap between the third limiting portion and the second body, an elastic member is sleeved on the second body, one end of the elastic member abuts against the first body, and the other end abuts against the second body, and at least a portion of the elastic member is located in the gap.

[0009] Through such an arrangement, that is, the elastic component is arranged to ensure that the second limiting portion and the third limiting portion are in limiting cooperation when the first body and the second body are assembled, thereby avoiding the second limiting portion and the third limiting portion from canceling the limiting cooperation without human intervention; in addition, the elastic component is sleeved on the second body, and at least a part of the elastic component is located in the gap between the third limiting portion and the second body, so that the elastic component is more stable during the deformation process and is not prone to abnormal deformation, thereby making the elastic component less prone to damage and extending the service life of the elastic component.

[0010] In the preferred technical solution of the above-mentioned shoe washing equipment, the second limiting portion is a groove formed on the inner wall of the containing structure, and a first protrusion is extended from the cylindrical surface of the second body toward the inner wall of the containing structure. The number of the third limiting portions is multiple, and the multiple third limiting portions are arranged along the circumference of the second body. The third limiting portion includes a connecting portion and a second protrusion. The connecting portion extends downward from the bottom of the first protrusion, and the second protrusion is arranged on the outside of the bottom of the connecting portion. When the first body and the second body are assembled, the second protrusion is stuck in the groove.

[0011] By such an arrangement, that is, the number of the third limiting parts is multiple, the first body and the second body can be further prevented from being separated when the first body and the second body are assembled, thereby ensuring that the first body and the second body are reliably assembled together.

[0012] In the preferred technical solution of the above-mentioned shoe washing equipment, the second protrusion includes a first inclined portion, a second inclined portion and a third inclined portion connected in sequence from top to bottom, the side of the first inclined portion away from the second body is arranged gradually away from the second body in a downward direction, the side of the second inclined portion away from the second body is arranged gradually away from the second body in a downward direction, the side of the third inclined portion away from the second body is arranged gradually close to the second body in a downward direction, and the inclination angle of the first inclined portion is greater than the inclination angle of the second inclined portion.

[0013] This arrangement facilitates the second protrusion to enter the groove during assembly of the first body and the second body, and facilitates the second protrusion to disengage from the groove to cancel the limiting fit during separation of the second body from the accommodating structure of the first body.

[0014] In the preferred technical solution of the above-mentioned shoe washing device, the first body includes a connected bristle mounting base and a connecting structure, the bristle mounting base is formed with a through-opening in the vertical direction, and the connecting structure is formed by extending downward from the bottom of the bristle mounting base, and the part of the bristle mounting base used to form the through-opening and the connecting structure together constitute the accommodating structure, the first limiting portion is arranged on the outside of the bottom of the connecting structure, and the connecting structure is passed through the opening structure. When the second body is located in the installation position, the second body abuts against the connecting structure so that the connecting structure is tightly against the inner side wall of the opening structure, so that the first limiting portion moves to the side away from the second body and thereby allows the first limiting portion to cooperate with the side of the opening structure close to the washing bucket.

[0015] Through such an arrangement, when the second body is in the installation position, the connecting structure can be tightly abutted against the inner side wall of the opening structure by abutting against the connecting structure, so that the first limiting portion moves to the side away from the second body and thus allows the first limiting portion to cooperate with the side of the opening structure close to the washing bucket. There is no need to further set up other structures to move the first limiting portion away from the side of the second body, and the structure is simple.

[0016] In the preferred technical solution of the above-mentioned shoe washing equipment, the second body is a cylinder, the first limiting parts and the connecting structures are multiple and one-to-one corresponding, multiple first limiting parts are arranged along the circumference of the second body, multiple connecting structures are arranged along the circumference of the second body, and the sides of multiple connecting structures away from the opening structure are arc-shaped surfaces, and each of the arc-shaped surfaces is located on the same cylindrical surface.

[0017] Through such an arrangement, that is, the number of the first limiting parts is multiple, it is possible to further avoid the first body from being separated from the impeller when the brush assembly and the impeller are assembled, thereby ensuring that the brush assembly is reliably installed on the impeller; in addition, the second body is a cylinder, and the sides of the multiple connecting structures away from the opening structure are arc-shaped surfaces, and each arc-shaped surface is located on the same cylindrical surface. Such an arrangement enables the second body to be well abutted against the connecting structure when the second body is in the installation position, thereby causing the first limiting part to move to the side away from the second body and thereby allowing the first limiting part to cooperate with the side of the opening structure close to the washing bucket.

[0018] In the preferred technical solution of the above-mentioned shoe washing equipment, the first limiting portion includes a first inclined structure, a second inclined structure and a third inclined structure connected in sequence from top to bottom, the side of the first inclined structure away from the second body is arranged gradually away from the second body in a downward direction, the side of the second inclined structure away from the second body is arranged gradually away from the second body in a downward direction, and the side of the third inclined structure away from the second body is arranged gradually close to the second body in a downward direction, and the inclination angle of the first inclined structure is greater than the inclination angle of the second inclined structure.

[0019] Through such an arrangement, it is convenient to cancel the limiting cooperation between the first limiting portion and the opening structure during the assembly of the brush assembly and the impeller so that the brush assembly can be removed from the impeller, and it is also convenient to pass the first limiting portion through the opening structure during the assembly process.

[0020] In the preferred technical solution of the above-mentioned shoe washing device, a recessed portion is formed on the top of the first body, and a third protrusion opposite to the recessed portion is formed extending from the cylindrical surface of the top of the second body toward the direction close to the recessed portion.

[0021] With this arrangement, when removing the second body from the first body, it is convenient for a user or maintenance personnel to insert their fingers into the recessed portion and hold the third protrusion, thereby separating the second body from the accommodating structure of the first body.

[0022] In the preferred technical solution of the above-mentioned shoe washing device, the internal space of the opening structure passes through the impeller, and the first limiting portion can cooperate with the bottom of the impeller to limit the position.

[0023] Through such an arrangement, the impeller can be processed to form an internal space with an open structure on the impeller. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0040] Based on the problem pointed out in the background art that the brush assembly in the existing shoe washing equipment is set on the impeller by screws, which makes it inconvenient to replace the brush assembly, the present invention provides a shoe washing equipment, which is intended to facilitate the disassembly, assembly and replacement of the brush assembly.

[0041] Specifically, the shoe washing device of the present invention includes a box body, a washing bucket, a pulsator and a brush assembly. The washing bucket is arranged in the box body, and the pulsator is arranged at the bottom of the washing bucket. Figure 1 and 2 As shown, an opening structure 11 is provided on the impeller 1, and the brush assembly 2 includes a first body 21, a second body 22 and bristles (not shown in the figure), a containing structure 211 is provided on the first body 21, the second body 22 is arranged in the containing structure 211, and the bristles are arranged on the first body 21 and / or the second body 22, and a first limiting portion 212 is provided on the first body 21. When the brush assembly 2 is assembled with the impeller 1, the second body 22 is located in the installation position so that the first limiting portion 212 moves to the side away from the second body 22 and thereby allows the first limiting portion 212 to cooperate with the side of the opening structure 11 close to the washing bucket to prevent the brush assembly 2 from being separated from the impeller 1, and the second body 22 can selectively separate from the first body 21 and thereby allow the first limiting portion 212 to move to the side away from the opening structure 11 so that the first limiting portion 212 separates from the opening structure 11.

[0042] It should be noted that the second body 22 can be selectively separated from the first body 21, that is, when the brush assembly 2 and the impeller 1 are assembled, the second body 22 is located in the containing structure 211 of the first body 21. When the brush assembly 2 needs to be removed from the impeller, the second body 22 is separated from the first body 21. Moreover, the separation of the second body 22 from the first body 21 can be that a part of the second body 22 extends from the containing structure 221 of the first body, or the entire second body 22 extends from the containing structure 221 of the first body (that is, the second body 22 is completely separated from the first body 21), as long as the first limiting portion 212 is allowed to move to the side away from the opening structure 11 under this degree of separation of the second body 22 from the first body 21.

[0043] Among them, the first limiting portion 212 can be a protrusion. At this time, the first limiting portion 212 can directly abut against the side of the opening structure 11 close to the washing bucket or abut against the groove structure formed on the side of the opening structure 11 close to the washing bucket to achieve limiting cooperation to prevent the brush assembly 2 from being separated from the impeller 1. The first limiting portion 212 can also adopt claws, buckles, etc. At this time, a hook and a bayonet are provided on the side of the opening structure 11 close to the washing bucket so that the first limiting portion 212 can be limited and cooperated with the side of the opening structure 11 close to the washing bucket to prevent the brush assembly 2 from being separated from the impeller 1. Those skilled in the art can flexibly set the first limiting portion 212 in actual applications, as long as the first limiting portion 212 can be limited and cooperated with the side of the opening structure 11 close to the washing bucket to prevent the brush assembly 2 from being separated from the impeller 1. Figure 2In the illustrated situation, the second body 22 is a cylinder, and the accommodating structure 211 of the first body 21 encloses a cylindrical space, and the diameter of at least a portion of the cylindrical space is slightly smaller than the diameter of the cylinder. When the second body 22 is in the installation position, at least a portion of the second body 22 is located in the cylindrical space with a diameter slightly smaller than that of the cylinder and abuts against the accommodating structure 211, stretching the accommodating structure 211 of the first body 21 to the four sides, thereby causing the first limiting portion 212 to move to the side away from the second body 22 and thereby allowing the first limiting portion 212 to cooperate with the side of the opening structure 11 close to the washing bucket to prevent the brush assembly 2 from separating from the pulsator 1. After the second body 22 is pulled out of the accommodating structure 211 of the first body 21, the first limiting portion 212 moves to the side away from the opening structure 11 so that the first limiting portion 212 separates from the opening structure 11; in another possible situation, the shape and size of the second body 22 is smaller than the shape and size of the space enclosed by the accommodating structure 211, A portion of the second body 22 is made of magnetic material, and at least a portion of the containing structure 211 of the first body 21 is made of a magnetic material with the same magnetic properties as the aforementioned magnetic material. When the second body 22 is located in the installation position, the portions of the first body 21 and the second body 22 having magnetic materials are close to each other, so that the first body 21 and the second body 22 are respectively subjected to forces that separate them from each other, so that the containing structure 211 of the first body 21 is away from the second body 22, thereby causing the first limiting portion 212 to move toward the side away from the second body 22 and thereby allowing the first limiting portion 212 to cooperate with the side of the opening structure 11 close to the washing bucket to prevent the brush assembly 2 from separating from the impeller 1, so that after the second body 22 is separated from the containing structure 211 of the first body 21, the portion of the first body 21 made of magnetic material is no longer subjected to the action of magnetic force, and the first limiting portion 212 moves toward the side away from the opening structure 11 to reset so that the first limiting portion 212 separates from the opening structure 11. Those skilled in the art can flexibly set the specific structures of the first body 21 and the second body 22 in actual applications, as long as when the brush assembly 2 and the impeller 1 are assembled, the second body 22 can enable the first limiting portion 212 to move to the side away from the second body 22 when it is in the installation position, and thereby allow the first limiting portion 212 to cooperate with the side of the opening structure 11 close to the washing bucket to prevent the brush assembly 2 from detaching from the impeller 1, and the second body 22 can selectively detach from the first body 21 and thereby allow the first limiting portion 212 to move to the side away from the opening structure 11 so that the first limiting portion 212 detaches from the opening structure 11.

[0044] Preferably, if Figure 2As shown, the internal space of the opening structure 11 is set through the impeller 1, and the first limiting portion 212 can cooperate with the bottom of the impeller 1. The bottom of the impeller 1 is actually the side of the opening structure 11 close to the washing tub. Through this arrangement, the impeller 1 can be processed to form the internal space of the opening structure 11 on the impeller 1.

[0045] Preferably, if Figure 3 As shown, the first limiting portion 212 includes a first inclined structure 2121, a second inclined structure 2122, and a third inclined structure 2123, which are sequentially connected from top to bottom. The side of the first inclined structure 2121 away from the second body 22 is arranged gradually away from the second body 22 in the downward direction, the side of the second inclined structure 2122 away from the second body 22 is arranged gradually away from the second body 22 in the downward direction, and the side of the third inclined structure 2123 away from the second body 22 is arranged gradually closer to the second body 22 in the downward direction. The inclination angle of the first inclined structure 2121 is greater than the inclination angle of the second inclined structure 2122. The inclination angle of the first inclined structure 2121 refers to the acute angle between the side of the first inclined structure 2121 away from the second body 22 and the downward direction, and the inclination angle of the second inclined structure 2122 refers to the acute angle between the side of the second inclined structure 2122 away from the second body 22 and the downward direction. Through such a setting, it is convenient to cancel the limiting cooperation between the first limiting portion 212 and the opening structure 11 during the assembly of the brush assembly 2 and the impeller 1 so that the brush assembly 2 can be removed from the impeller 1, and it is also convenient to pass the first limiting portion 212 through the opening structure 11 during the assembly process.

[0046] Preferably, if Figure 2 As shown, the first body 21 includes a connected bristle mounting base 214 and a connecting structure 215. The bristle mounting base 214 is formed with a through-hole in the vertical direction. The connecting structure 215 is formed by extending downward from the bottom of the bristle mounting base 214. The part of the bristle mounting base 214 used to form the through-hole and the connecting structure 215 together constitute a accommodating structure 211. The first limiting portion 212 is arranged on the outside of the bottom of the connecting structure 215. The connecting structure 215 is passed through the opening structure 11. When the second body 22 is in the installation position, the second body 22 abuts against the connecting structure 215 so that the connecting structure 215 is tightly against the inner side wall of the opening structure 11, thereby moving the first limiting portion 212 to the side away from the second body 22 and thereby allowing the first limiting portion 212 to cooperate with the side of the opening structure 11 close to the washing bucket. Figure 2In the illustrated case, the bristle mounting base 214 includes a connected hemispherical structure and a cylindrical structure, the axis of the through-hole coincides with the axis of the hemispherical structure and the cylindrical structure, the connecting structure 215 extends downward from the bottom of the cylindrical structure around the through-hole, and the bristles (not shown in the figure) are covered with the outer side of the cylindrical structure and the outer surface of the spherical structure. Of course, the bristle mounting base 214 can also be set as a triangular prism structure, a rectangular parallelepiped structure, etc. Those skilled in the art can flexibly set the specific structure of the bristle mounting base 214 in actual application. Such adjustments and changes to the bristle mounting base 214 do not constitute a limitation of the present invention and should be limited within the scope of protection of the present invention. In addition, the specific structure of the first body 21 is not limited to the above. For example, alternatively, the first body 21 only includes a connecting structure 215 that is inserted into the opening structure 11, and does not have a bristle mounting base 214. In this case, all the bristles are set on the second body 22.

[0047] Preferably, if Figure 1 and 2 As shown, the second body 22 is a cylinder, and there are multiple first limiting portions 212 and connecting structures 215 in one-to-one correspondence. Multiple first limiting portions 212 are arranged along the circumference of the second body 22, and multiple connecting structures 215 are arranged along the circumference of the second body 22. The sides of the multiple connecting structures 215 away from the opening structure 11 are arc-shaped surfaces, and each arc-shaped surface is located on the same cylindrical surface. Through such an arrangement, that is, the number of the first limiting parts 212 is multiple, it is possible to further avoid the first body 21 from being separated from the impeller 1 when the brush assembly 2 and the impeller 1 are assembled, thereby ensuring that the brush assembly 2 is reliably installed on the impeller 1; in addition, the second body 22 is a cylinder, and the sides of the multiple connecting structures 215 away from the opening structure 11 are arc-shaped surfaces, and each arc-shaped surface is located on the same cylindrical surface. Such an arrangement enables the second body 22 to be well abutted against the connecting structure 215 when the second body 22 is in the installation position, thereby causing the first limiting part 212 to move to the side away from the second body 22 and thereby allowing the first limiting part 212 to cooperate with the side of the opening structure 11 close to the washing bucket.

[0048] Preferably, if Figure 1 、 2As shown in Figures 9 and 10, a second limiting portion 213 is provided on the inner side wall of the containing structure 211, and a third limiting portion 221 is provided on the second body 22. When the first body 21 and the second body 22 are assembled, the second limiting portion 213 and the third limiting portion 221 cooperate to position the second body 22 in an installation position. The second limiting portion 213 and the third limiting portion 221 can respectively adopt magnets with different magnetic properties. The second limiting portion 213 can also adopt a claw or a buckle. Correspondingly, the third limiting portion 221 can also adopt a hook or a bayonet. Those skilled in the art can flexibly set the specific structure of the second limiting portion 213 and the third limiting portion 221 in actual application, as long as the second limiting portion 213 and the third limiting portion 221 can cooperate to position.

[0049] In the first possible case of the above preferred situation, if Figure 9 and 10 As shown, the first body 21 and the second body 22 are limited only by the second limiting portion 213 and the third limiting portion 221 so that the second body 22 is located in the installation position. Figure 11 As shown, the second limiting portion 213 is a groove formed on the inner sidewall of the containing structure 211. A first protrusion 222 extends from the cylindrical surface of the second body 22 toward the inner sidewall of the containing structure 211. There are multiple third limiting portions 221, and the multiple third limiting portions 221 are arranged along the circumference of the second body 22. The third limiting portion 221 includes a connecting portion 2211 and a second protrusion 2212. The connecting portion 2211 extends downward from the bottom of the first protrusion 222, and the second protrusion 2212 is arranged outside the bottom of the connecting portion 2211. When the first body 21 and the second body 22 are assembled, the second protrusion 2212 abuts the lower side of the groove. The side surfaces of the multiple connecting portions 2211 near the second body 22 are arcuate surfaces, and each arcuate surface is located on the same cylindrical surface. Of course, the side surfaces of the connecting portions 2211 near the second body 22 are not limited to arcuate surfaces, and can also be flat surfaces. The groove can be a plurality of mutually spaced grooves, or can be an annular groove surrounding the inner wall of the containing structure 211. Similarly, the first protrusion 222 can also be a plurality of mutually spaced protrusions, or can be an annular protrusion surrounding the inner wall of the containing structure 211.

[0050] In the second possible scenario of the above preferred scenario, if Figure 2As shown, the second body 22 is a cylinder, and there is a gap between the third limiting portion 221 and the second body 22. An elastic member 23 is sleeved on the second body 22, and one end of the elastic member 23 abuts against the first body 21, and the other end abuts against the second body 22, and at least a portion of the elastic member 23 is located in the gap. Among them, the elastic member 23 can be made of a spring, rubber, etc., and those skilled in the art can flexibly set the specific structure of the elastic member 23 in actual application. Such changes and adjustments to the specific structure of the elastic member 23 do not constitute a limitation of the present invention and should be limited within the scope of protection of the present invention. Through such a setting, that is, by setting the elastic member 23, the elastic force of the elastic member 23 ensures the limiting cooperation between the second limiting portion 213 and the third limiting portion 221, preventing the second limiting portion 213 and the third limiting portion 221 from easily separating from each other. Of course, those skilled in the art need to reasonably select the specific model and specifications of the elastic member 23 so as to reasonably set the elastic force of the elastic member 23 when the second body 22 and the first body 21 are assembled, so that the elastic member 23 can ensure that the second limiting portion 213 and the third limiting portion 221 are tightly matched. The user can directly pull the second body 22 upward from the accommodating structure 211 of the first body 21 with force. The setting of the elastic member 23 makes it relatively labor-saving to pull the second body 22 upward. Further preferably, as Figures 4 to 6 As shown, the second limiting portion 213 is a groove formed on the inner sidewall of the containing structure 211. A first protrusion 222 extends from the cylindrical surface of the second body 22 toward the inner sidewall of the containing structure 211. There are multiple third limiting portions 221, each of which is arranged along the circumference of the second body 22. The third limiting portion 221 includes a connecting portion 2211 and a second protrusion 2212. The connecting portion 2211 extends downward from the bottom of the first protrusion 222, and the second protrusion 2212 is arranged outside the bottom of the connecting portion 2211. When the first and second bodies 21 and 22 are assembled, the second protrusion 2212 abuts against the lower side of the groove. The sides of the multiple connecting portions 2211 near the second body 22 are arcuate surfaces, each of which is located on the same cylindrical surface. A gap is formed between the connecting portion 2211 and the second body 22. Of course, the side of the connecting portion 2211 near the second body 22 is not limited to an arcuate surface, but can also be a flat surface. The groove can be a plurality of mutually spaced grooves, or can be an annular groove surrounding the inner wall of the containing structure 211. Similarly, the first protrusion 222 can also be a plurality of mutually spaced protrusions, or can be an annular protrusion surrounding the inner wall of the containing structure 211.

[0051] In the second possible situation above, it is further preferred that Figure 4As shown, the second protrusion 2212 includes a first inclined portion 22121, a second inclined portion 22122, and a third inclined portion 22123, which are sequentially connected from top to bottom. The side of the first inclined portion 22121 away from the second body 22 is gradually away from the second body 22 in the downward direction, the side of the second inclined portion 22122 away from the second body 22 is gradually away from the second body 22 in the downward direction, and the side of the third inclined portion 22123 away from the second body 22 is gradually closer to the second body 22 in the downward direction. The inclination angle of the first inclined portion 22121 is greater than the inclination angle of the second inclined portion 22122. The inclination angle of the first inclined portion 22121 refers to the acute angle between the side of the first inclined portion 22121 away from the second body 22 and the downward direction, and the inclination angle of the second inclined portion 22122 refers to the acute angle between the side of the second inclined portion 22122 away from the second body 22 and the downward direction. This arrangement facilitates the second protrusion to enter the groove during the assembly of the first and second bodies, and facilitates the second protrusion to disengage from the groove to cancel the position-limiting fit during the separation of the second body from the receiving structure of the first body. Of course, in the first possible scenario described above, the preferred solution described in this paragraph can also be adopted.

[0052] Preferably, if Figure 7 and 8 As shown, a recessed portion 216 is formed at the top of the first body 21, and a third protrusion 223 is formed from the cylindrical surface of the top of the second body 22 in a direction close to the recessed portion 216 to form a third protrusion 223 opposite to the recessed portion 216. When removing the second body 22 from the first body 21, it is convenient for the user or maintenance personnel to insert their fingers into the recessed portion 216 and hold the third protrusion 223, thereby separating the second body 22 from the containing structure 211 of the first body 21. The third protrusion 223 can be a plurality of protrusions spaced apart from each other. In a more preferred embodiment, continue to refer to Figure 7 and 8 The third protrusion 223 is an annular protrusion that surrounds the cylindrical surface at the top of the second body 22, and is provided with a plurality of fourth protrusions 224. When a user grasps the third protrusion 223, their hand comes into contact with the fourth protrusions 224, which increase friction and prevent the second body 22 from slipping out of their hand. Of course, a grip portion can also be provided on the top surface of the second body 22. When removing the second body 22 from the first body 21, the user or maintenance personnel can directly grasp the grip portion to disengage the second body 22 from the housing structure 211 of the first body 21.
