Description

Technical Field

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

[0002] Shoe washing devices are a new type of household appliance that has emerged in the market in recent years. Before the appearance of shoe washing devices, people sometimes used laundry devices, such as pulsator washing machines, to wash shoes. However, shoes often come into contact with the ground during wearing, resulting in more dirt and dust adhering to the shoes. This causes the dirt on the shoes to enter the inner and outer barrels of the pulsator washing machine during the process of washing shoes with the pulsator washing machine, contaminating the inner and outer barrels of the pulsator washing machine. Subsequently, when using the pulsator washing machine to wash clothes, the clothes will be contaminated, which is not conducive to the health of users. The appearance of shoe washing devices enables people to wash shoes without using laundry devices, avoiding the contamination of laundry devices by shoes, and thus avoiding the contamination of clothes during the washing process. In existing washing devices, a brush roller is usually provided on the pulsator at the bottom of its washing barrel, and the shoes are washed by the bristles on the brush roller. However, the brush roller is usually integrally provided with the pulsator, that is, the brush roller is fixed on the pulsator and cannot be removed, which is not convenient for replacing the brush roller when the bristles on the brush roller are damaged.

[0003] Therefore, there is a need in the art for a new shoe washing device to solve the above problems. Summary of the Invention

[0004] In order to solve the above problems in the prior art, that is, to solve the problem that the brush roller in the existing shoe washing device cannot be removed from the pulsator and is not convenient for replacing the brush roller when the bristles on the brush roller are damaged, the present invention provides a shoe washing device, which includes a box body, a washing barrel, a pulsator and a brush assembly. The washing barrel is arranged in the box body, the pulsator is arranged at the bottom of the washing barrel, the pulsator 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 receiving structure, the second body is arranged in the receiving structure, the bristles are arranged on the first body and / or the second body. The first body is provided with a first limiting portion, and a recessed portion is formed on the second body. In the case where the brush assembly is assembled with the pulsator, the second body is located at a first position so that the first limiting portion moves away from the second body and thus allows the first limiting portion to be in limiting cooperation with the side of the opening structure close to the washing barrel to prevent the brush assembly from detaching from the pulsator, and the second body can be selectively moved to a second position so that the recessed portion is opposite to the first limiting portion and thus allows the first limiting portion to move towards the recessed portion side so that the first limiting portion disengages from the opening structure.

[0005] With such a setting, when the brush assembly and the wave wheel are assembled, moving the second body to the second position can make the first limiting portion move towards the concave portion, facilitating the first limiting portion to disengage from the opening structure so that the brush assembly can be removed from the wave wheel; in addition, during the assembly of the brush assembly and the wave wheel, moving the second body to the second position can make the first limiting portion move towards the concave portion, facilitating the first limiting portion to pass through the opening structure during the assembly process; such a structural setting facilitates the disassembly and replacement of the brush assembly. Moreover, after the brush assembly is disassembled, the shoe washing device can be used for washing clothes, making the functions of the shoe washing device diversified.

[0006] In the preferred technical solution of the above-mentioned shoe washing device, an elastic member is arranged between the first body and the second body, a second limiting portion is arranged on the inner side wall of the accommodating structure, and a third limiting portion is arranged on the second body. When the first body and the second body are assembled, the elastic member can make the second body located at the first position and make the second limiting portion and the third limiting portion be in limiting cooperation.

[0007] With such a setting, that is, by arranging the elastic member, the second limiting portion and the third limiting portion, the second body can be kept at the first position, and the structure is simple and easy to implement.

[0008] In the preferred technical solution of the above-mentioned shoe washing device, the second body is a cylinder, the number of the third limiting portions is multiple, the multiple third limiting portions are arranged along the circumferential direction of the second body and have a gap with the second body, the elastic member is a spring sleeved on the second body, and at least a part of the elastic member is located in the gap.

[0009] With such a setting, that is, the number of the third limiting portions is multiple, which can further prevent the first body and the second body from separating when the first body and the second body are assembled, so as to ensure that the first body and the second body are reliably assembled together; in addition, the second body is a cylinder, the elastic member is a spring sleeved on the second body, and at least a part of the elastic member is located in the gap. Such a setting makes the spring more stable during the deformation process, not easily undergo abnormal deformation deviating from the spring axis, so that the spring is not easily damaged and the service life of the spring is prolonged.

[0010] In the preferred technical solution of the above shoe-washing device, the second limiting portion is a first protrusion formed on the inner side wall of the accommodating structure, a second protrusion extends from the cylindrical surface of the second body towards the inner side wall of the accommodating structure, the third limiting portion includes a connecting portion and a third protrusion, the connecting portion extends downward from the bottom of the second protrusion, the third protrusion is arranged outside the bottom of the connecting portion, in the case where the first body and the second body are assembled, the third protrusion abuts against the lower side of the first protrusion, the sides of the plurality of connecting portions close to the second body are arc-shaped surfaces, and each arc-shaped surface is located on the same cylindrical surface, and the gap is formed between the connecting portion and the second body.

[0011] With such a setting, when the second body is a cylinder and the elastic member is a spring sleeved on the second body, the sides of the plurality of connecting portions close to the second body are arc-shaped surfaces, and each arc-shaped surface is located on the same cylindrical surface, and the gap is formed between the connecting portion and the second body, so that the connecting portion and the second body can better keep the spring stable during the deformation process of the spring, and it is not easy to occur abnormal deformation deviating from the axis of the spring, thereby making the spring less likely to be damaged and further extending the service life of the spring.

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

[0013] With such a setting, it is not only convenient for the third protrusion to pass through the first protrusion and finally be located below the first protrusion during the process of assembling the first body and the second body, but also convenient for the third protrusion and the first protrusion to cancel the limiting cooperation during the process of taking out the second body from the accommodating structure of the first body.

[0014] In the preferred technical solution of the above shoe-washing device, a fourth protrusion is arranged on the second body, and when the second body is moved to the second position, the fourth protrusion is in limiting cooperation with the first protrusion.

[0015] With such a setting, when the second body is moved to the second position, it is convenient for the second body to stay in the second position, that is to say, it is convenient for the first limiting portion and the recessed portion to stay in the corresponding positions, so that the first limiting portion can move towards the recessed portion side, thereby facilitating the first limiting portion to disengage from the opening structure.

[0016] In the preferred technical solution of the above shoe-washing device, the first body includes a brush mounting base and a connecting structure connected to each other. The brush mounting base is formed with a through hole in the vertical direction. The connecting structure extends downward from the bottom of the brush mounting base. The part of the brush mounting base for forming the through hole and the connecting structure together constitute the accommodating structure. The first limiting part is arranged on the outer side of the bottom of the connecting structure. The connecting structure is inserted into the opening structure. When the second body is in the first position, the second body abuts against the connecting structure so that the connecting structure tightly abuts against the inner side wall of the opening structure, thereby causing the first limiting part to move away from the second body and thus allowing the first limiting part to be in limiting cooperation with the side of the opening structure close to the washing tub.

[0017] With such an arrangement, when the second body is in the first position, by abutting against the connecting structure, the connecting structure can be tightly abutted against the inner side wall of the opening structure, thereby causing the first limiting part to move away from the second body and thus allowing the first limiting part to be in limiting cooperation with the side of the opening structure close to the washing tub, without the need to further provide other structures to move the first limiting part away from the second body, and the structure is simple.

[0018] In the preferred technical solution of the above shoe-washing device, the second body is a cylinder. Both the first limiting part and the connecting structure are multiple and correspond to each other one by one. The multiple first limiting parts are arranged along the circumferential direction of the second body. The multiple connecting structures are arranged along the circumferential direction of the second body. The side surfaces 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.

[0019] With such an arrangement, that is, the number of the first limiting parts is multiple, it can further prevent the first body from detaching from the impeller when the brush assembly and the impeller are assembled, so as to ensure that the brush assembly is reliably installed on the impeller; in addition, the second body is a cylinder, the side surfaces 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. With such an arrangement, when the second body is in the first position, the second body can well abut against the connecting structure, thereby causing the first limiting part to move away from the second body and thus allowing the first limiting part to be in limiting cooperation with the side of the opening structure close to the washing tub.

[0020] In the preferred technical solution of the above-mentioned shoe-washing device, the first limiting portion includes a first inclined structure, a second inclined structure, and a third inclined structure that are connected in sequence from top to bottom. The side surface of the first inclined structure away from the second body is gradually away from the second body in the downward direction. The side surface of the second inclined structure away from the second body is gradually away from the second body in the downward direction. The side surface of the third inclined structure away from the second body is gradually approaching the second body in the downward direction. The inclination angle of the first inclined structure is greater than the inclination angle of the second inclined structure.

[0021] With such a setting, it is convenient to cancel the limiting cooperation between the first limiting portion and the opening structure during the process of assembling the brush assembly and the wave wheel so that the brush assembly can be removed from the wave wheel, and it is also convenient for the first limiting portion to pass through the opening structure during the assembling process.

[0022] In the preferred technical solution of the above-mentioned shoe-washing device, the internal space of the opening structure penetrates through the wave wheel, and the first limiting portion can be in limiting cooperation with the bottom of the wave wheel.

[0023] With such a setting, it is possible to facilitate the processing of the wave wheel to form the internal space of the opening structure on the wave wheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

In addition, the terms "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0036] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Based on the problem pointed out in the background technology that the brush roller in the existing shoe washing equipment cannot be removed from the agitator, which is not convenient for replacing the brush roller when the bristles on the brush roller are damaged, the present invention provides a shoe washing equipment, aiming to facilitate the replacement of the bristled components.

[0038] Specifically, the shoe-washing device of the present invention includes a box body, a washing tub, a wave wheel, and a brush assembly. The washing tub is disposed inside the box body, and the wave wheel is disposed at the bottom of the washing tub. As Figure 1 and 2 shown, an opening structure 11 is provided on the wave wheel 1. The brush assembly 2 includes a first body 21, a second body 22, and bristles (not shown in the figure). A receiving structure 211 is provided on the first body 21. The second body 22 is disposed in the receiving structure 211. The bristles are provided on the first body 21 and / or the second body 22 (that is, the bristles are only provided on the first body 21, or some bristles are provided on the first body 21 and some bristles are provided on the second body 22, or the bristles are only provided on the second body 22). A first limiting portion 212 is provided on the first body 21, and a recessed portion 221 is formed on the second body 22. When the brush assembly 2 is assembled with the wave wheel 1, the second body 22 is located at the first position so that the first limiting portion 212 moves away from the second body 22 and thus allows the first limiting portion 212 to be in limiting cooperation with the side of the opening structure 11 close to the washing tub to prevent the brush assembly 2 from disengaging from the wave wheel 1. And the second body 22 can be selectively moved to the second position so that the recessed portion 221 faces the first limiting portion 212 and thus allows the first limiting portion 212 to move towards the recessed portion 221 so that the first limiting portion 212 disengages from the opening structure 11.

[0039] It should be noted that the second body 22 can be selectively moved to the second position. That is to say, when the brush assembly 2 is assembled with the wave wheel 1, the second body 22 is located at the first position. When it is necessary to remove the brush assembly 2 from the wave wheel, the second body 22 is moved to the second position.

[0040] 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 tub or abut against a groove structure formed on the side of the opening structure 11 close to the washing tub to achieve limiting cooperation to prevent the brush assembly 2 from disengaging from the wave wheel 1. The first limiting portion 212 can also be a claw, a buckle, etc. At this time, a hook and a bayonet are provided on the side of the opening structure 11 close to the washing tub so that the first limiting portion 212 is in limiting cooperation with the side of the opening structure 11 close to the washing tub to prevent the brush assembly 2 from disengaging from the wave wheel 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 in limiting cooperation with the side of the opening structure 11 close to the washing tub to prevent the brush assembly 2 from disengaging from the wave wheel 1. In Figure 2In the illustrated scenario, the second body 22 is a cylinder, and the receiving structure 211 of the first body 21 encloses a cylindrical space. The diameter of at least a part of the cylindrical space is slightly smaller than the diameter of the cylinder. When the second body 22 is in the first position, at least a part of the second body 22 is located in the cylindrical space with a slightly smaller diameter and abuts against the receiving structure 211, pushing the receiving structure 211 of the first body 21 outwards in all directions, so that the first limiting portion 212 moves towards the side away from the second body 22 and thus allows the first limiting portion 212 to be in limiting cooperation with the side of the opening structure 11 close to the washing tub to prevent the brush assembly 2 from detaching from the impeller 1. Press down the second body 22 to move it to the second position, and the first limiting portion 212 will move towards the recessed portion 221 side so that the first limiting portion 212 disengages from the opening structure 11; in another possible scenario, the shape and size of the second body 22 are smaller than the shape and size of the space enclosed by the receiving structure 211. A part of the second body 22 is made of a magnetic material, and at least a part of the receiving structure 211 of the first body 21 is made of a magnetic material with the same magnetism as the aforementioned magnetic material. When the second body 22 is in the first position, the parts of the first body 21 and the second body 22 each having the magnetic material are close to each other, causing the first body 21 and the second body 22 to be respectively subjected to forces that push them away from each other, causing the receiving structure 211 of the first body 21 to move away from the second body 22, so that the first limiting portion 212 moves towards the side away from the second body 22 and thus allows the first limiting portion 212 to be in limiting cooperation with the side of the opening structure 11 close to the washing tub to prevent the brush assembly 2 from detaching from the impeller 1. Move the second body 22 to the second position. At this position, the part of the first body 21 made of the magnetic material is no longer subjected to the magnetic force, and the first limiting portion 212 will move towards the recessed portion 221 side to reset so that the first limiting portion 212 disengages 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 second body 22 is in the first position after the brush assembly 2 and the impeller 1 are assembled, it can cause the first limiting portion 212 to move towards the side away from the second body 22 and thus allow the first limiting portion 212 to be in limiting cooperation with the side of the opening structure 11 close to the washing tub to prevent the brush assembly 2 from detaching from the impeller 1, and when the second body 22 is in the second position, it can cause the recessed portion 221 to be opposite to the first limiting portion 212 so that the first limiting portion 212 disengages from the opening structure 11.

[0041] Preferably, as Figure 2 and 5 shown, the internal space of the opening structure 11 penetrates through the impeller 1, and the first limiting portion 212 can be in limiting cooperation with the bottom of the impeller 1. In fact, the bottom of the impeller 1 is also the side of the opening structure 11 close to the washing tub. Through such a setting, it is possible to process the impeller 1 to form the internal space of the opening structure 11 on the impeller 1.

[0042] Preferably, as Figure 3 shown, the first limiting portion 212 includes a first inclined structure 2121, a second inclined structure 2122, and a third inclined structure 2123 that are connected in sequence from top to bottom. The side surface of the first inclined structure 2121 away from the second body 22 is arranged to gradually move away from the second body 22 in the downward direction. The side surface of the second inclined structure 2122 away from the second body 22 is arranged to gradually move away from the second body 22 in the downward direction. The side surface of the third inclined structure 2123 away from the second body 22 is arranged to gradually approach 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. Wherein, the inclination angle of the first inclined structure 2121 refers to the acute angle formed by the side surface of the first inclined structure 2121 away from the second body 22 and the downward direction. The inclination angle of the second inclined structure 2122 refers to the acute angle formed by the side surface of the second inclined structure 2122 away from the second body 22 and the downward direction. Through such an arrangement, it is convenient to cancel the limiting cooperation between the first limiting portion 212 and the opening structure 11 during the assembly process of the brush assembly 2 and the wave wheel 1 so that the brush assembly 2 can be removed from the wave wheel 1, and it is also convenient for the first limiting portion 212 to pass through the opening structure 11 during the assembly process.

[0043] Preferably, as Figure 2 and 5 shown, the first body 21 includes a brush hair mounting base 214 and a connecting structure 215 that are connected. The brush hair mounting base 214 is formed with a through hole in the vertical direction. The connecting structure 215 extends downward from the bottom of the brush hair mounting base 214. The part of the brush hair mounting base 214 used to form the through hole and the connecting structure 215 together constitute a receiving structure 211. The first limiting portion 212 is arranged on the outer side of the bottom of the connecting structure 215. The connecting structure 215 is inserted into the opening structure 11. When the second body 22 is in the first position, the second body 22 abuts against the connecting structure 215 so that the connecting structure 215 tightly abuts against the inner side wall of the opening structure 11, thereby causing the first limiting portion 212 to move away from the second body 22 and thus allowing the first limiting portion 212 to be in limiting cooperation with the side of the opening structure 11 close to the washing tub. In Figure 2 and 5In the shown case, the bristle mounting base 214 includes a connected hemispherical structure and a cylindrical structure. The axis of the through hole coincides with the axes of both the hemispherical structure and the cylindrical structure. The connecting structure 215 extends downward from the bottom of the cylindrical structure around the through hole. Bristles (not shown in the figure) cover the outer side surface 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 cuboid structure, etc. Those skilled in the art can flexibly set the specific structure of the bristle mounting base 214 in practical applications. Such adjustments and changes to the bristle mounting base 214 do not constitute a limitation to the present invention and should all be defined within the protection scope 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 the connecting structure 215 inserted into the opening structure 11 and does not have the bristle mounting base 214. At this time, all the bristles are arranged on the second body 22.

[0044] Preferably, as Figure 5 and 6 shown, the second body 22 is a cylinder, the recessed portion 221 is formed on the cylinder, both the first limiting portions 212 and the connecting structures 215 are multiple and correspond one by one. The multiple first limiting portions 212 are arranged along the circumferential direction of the second body 22, the multiple connecting structures 215 are arranged along the circumferential direction of the second body 22, and the side surfaces 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 a setting, that is, the number of the first limiting portions 212 is multiple, it can further prevent the first body 21 from detaching from the wave wheel 1 when the brush assembly 2 and the wave wheel 1 are assembled, thus ensuring that the brush assembly 2 is reliably mounted on the wave wheel 1. In addition, the second body 22 is a cylinder, the side surfaces 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 a setting enables the second body 22 to be in good contact with the connecting structure 215 when the second body 22 is in the first position, so that the first limiting portions 212 move to the side away from the second body 22 and thus allows the first limiting portions 212 to be in limiting cooperation with the side of the opening structure 11 close to the washing tub.

[0045] Preferably, as Figure 2 、 4As shown in FIGS. 5, an elastic member 23 is provided between the first body 21 and the second body 22. A second limiting portion 213 is provided on the inner side wall of the accommodating structure 211, and a third limiting portion 222 is provided on the second body 22. When the first body 21 and the second body 22 are assembled, the elastic member 23 can make the second body 22 located at the first position and make the second limiting portion 213 and the third limiting portion 222 in limiting cooperation. That is to say, the elastic force of the elastic member 23 can make the second limiting portion 213 and the third limiting portion 222 approach each other, so that the second limiting portion 213 and the third limiting portion 222 are in limiting cooperation, and further make the second body 22 located at the first position. Among them, the elastic member 23 can be a spring, rubber, etc. Those skilled in the art can flexibly set the specific structure of the elastic member 23 in actual applications, as long as the elastic member 23 can make the second body 22 located at the first position and make the second limiting portion 213 and the third limiting portion 222 in limiting cooperation when the first body 21 and the second body 22 are assembled. The second limiting portion 213 can be a protrusion, and correspondingly, the third limiting portion 222 can also be a protrusion; in addition, the second limiting portion 213 can also be a claw or a buckle, and correspondingly, the third limiting portion 222 can also be a hook or a bayonet (in this case, the elastic member 23 may not be provided between the first body 21 and the second body 22). Those skilled in the art can flexibly set the specific structures of the second limiting portion 213 and the third limiting portion 222 in actual applications, as long as the second limiting portion 213 and the third limiting portion 222 can be in limiting cooperation.

[0046] Preferably, as Figure 2 and 4 shown, the second body 22 is a cylinder, the recessed portion 221 is formed on the cylinder, the number of the third limiting portions 222 is multiple, the multiple third limiting portions 222 are arranged along the circumferential direction of the second body 22 and have a gap with the second body 22, the elastic member 23 is a spring sleeved on the second body 22, and at least a part of the elastic member 23 is located in the gap. Through such a setting, that is, the number of the third limiting portions 222 is multiple, it can further prevent the first body 21 and the second body 22 from being separated when the first body 21 and the second body 22 are assembled, so as to ensure that the first body 21 and the second body 22 are reliably assembled together; in addition, the second body 22 is a cylinder, the elastic member 23 is a spring sleeved on the second body 22, and at least a part of the elastic member 23 is located in the gap. Such a setting makes the spring more stable during the deformation process and not easily deviate from the spring axis for abnormal deformation, so that the spring is not easily damaged and the service life of the spring is extended.

[0047] Preferably, as Figure 2 and 4As shown, the second limiting portion 213 is a first protrusion formed on the inner sidewall of the accommodating structure 211. A second protrusion 223 extends from the cylindrical surface of the second body 22 towards the inner sidewall of the accommodating structure 211. The third limiting portion 222 includes a connecting portion 2221 and a third protrusion 2222. The connecting portion 2221 extends downward from the bottom of the second protrusion 223, and the third protrusion 2222 is disposed outside the bottom of the connecting portion 2221. In the case where the first body 21 and the second body 22 are assembled, the third protrusion 2222 abuts against the lower side of the first protrusion. The sides of the plurality of connecting portions 2221 close to the second body 22 are arc-shaped surfaces, and each arc-shaped surface is located on the same cylindrical surface. A gap is formed between the connecting portion 2221 and the second body 22. Among them, the first protrusion may be a plurality of spaced-apart protrusions, or may be an annular protrusion surrounding the inner sidewall of the accommodating structure 211. Similarly, the second protrusion 223 may also be a plurality of spaced-apart protrusions, or may be an annular protrusion surrounding the inner sidewall of the accommodating structure 211.

[0048] Preferably, as Figure 4 shown, the third protrusion 2222 includes a first inclined portion 22221, a second inclined portion 22222, and a third inclined portion 22223 connected in sequence from top to bottom. The side of the first inclined portion 22221 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 22222 away from the second body 22 is gradually away from the second body 22 in the downward direction. The side of the third inclined portion 22223 away from the second body 22 is gradually close to the second body 22 in the downward direction. The inclination angle of the first inclined portion 22221 is greater than the inclination angle of the second inclined portion 22222. Among them, the inclination angle of the first inclined portion 22221 refers to the acute angle formed between the side of the first inclined portion 22221 away from the second body 22 and the downward direction. The inclination angle of the second inclined portion 22222 refers to the acute angle formed between the side of the second inclined portion 22222 away from the second body 22 and the downward direction. Through such a setting, it is convenient for the third protrusion 2222 to pass through the first protrusion and finally be located below the first protrusion during the assembly process of the first body 21 and the second body 22, and it is also convenient for the third protrusion 2222 to cancel the limiting cooperation with the first protrusion during the process of removing the second body 22 from the accommodating structure 211 of the first body 21.

[0049] Preferably, as Figure 5As shown, the second body 22 is provided with a fourth protrusion 224. When the second body 22 is moved to the second position, the fourth protrusion 224 cooperates with the first protrusion. Through such a configuration, when the second body 22 is moved to the second position, it is convenient for the second body 22 to remain in the second position, that is, it is convenient for the first limiting portion 212 and the recessed portion 221 to remain in corresponding positions, so that the first limiting portion 212 moves toward the side of the recessed portion 221, thereby facilitating the first limiting portion 212 to be separated from the opening structure 11. Further preferably, as Figure 7 and 8 As shown, a recessed structure 216 is formed on the top of the first body 21. When the second body 22 is in the first position, the fourth protrusion 224 is opposite to the recessed structure 216. When the second body 22 is removed from the first body 21, it is convenient for the user or maintenance personnel to insert their fingers into the recessed structure 216 and hold the fourth protrusion 224, so that the second body 22 is separated from the accommodation structure of the first body 21. The fourth protrusion 224 can be a plurality of mutually spaced protrusions. In a more preferred case, as shown in FIG. Figure 7 and 8 As shown, the fourth protrusion 224 is an annular protrusion surrounding the cylindrical surface at the top of the second body 22, and a plurality of fifth protrusions 225 are provided on the annular protrusion. When the user holds the fourth protrusion 224, the hand will contact the fifth protrusion 225, and the fifth protrusion 225 can increase the friction force to prevent the second body 22 from slipping from the hand. Of course, a gripping portion can also be provided on the top surface of the top of the second body 22. When the second body 22 is removed from the first body 21, the user or maintenance personnel can directly hold the gripping portion to separate the second body 22 from the containing structure 211 of the first body 21.
