[0037] A water surface cleaning device is a device used to remove debris and pollutants from the surface of water. It mainly uses physical principles (such as static pressure adsorption, mechanical collection, etc.) for cleaning. It can be applied to a variety of scenarios such as urban rivers, reservoirs, swimming pools, aquariums, water parks, etc., and is widely used.

[0038] In some cases, the water surface cleaning device includes a shell and a sealed cabin disposed in the shell, and the sealed cabin can accommodate electrical components that are susceptible to humid environments in partitions to achieve sealed isolation and enhanced protection of these electrical components. However, the electrical components disposed in the sealed cabin need to be electrically connected to the electrical components disposed outside the sealed cabin, and in some scenarios (such as inspection scenarios and post-maintenance scenarios), the electrical connection between them may need to be temporarily disconnected, resulting in poor connection convenience and disconnection convenience.

[0039] Therefore, the embodiment of the present application provides a water surface cleaning device, which can improve the connection convenience and disconnection convenience of the electrical connection between the electrical components arranged in the sealed cabin and the electrical components arranged outside the sealed cabin.

[0040] The specific implementation of this application is described in detail below in conjunction with specific embodiments:

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Some embodiments of the present application provide a water surface cleaning device, including a shell 10, a sealed cabin 20 and an electrical connector 30, wherein the sealed cabin 20 is disposed in the shell 10; the electrical connector 30 is disposed in the sealed cabin 20, and the electrical connector 30 includes a male connector 31 and a female connector 32 that are plugged into each other, and the female connector 32 can move in a direction close to or away from the male connector 31 while maintaining plugging with the male connector 31.

[0042] It should be noted that the shell 10 is an outer shell component of the water surface cleaning device, and components such as a trash basket may be disposed inside the shell 10 .

[0043] The sealed cabin 20 is disposed in the housing 10, and the internal space of the sealed cabin 20 is sealed and isolated from the internal space of the housing 10 outside the sealed cabin 20, which can effectively prevent water and moisture from directly invading the sealed cabin 20. The structure of the sealed cabin 20 can be designed in a variety of ways. Figure 2 As shown, in some embodiments, the sealed capsule 20 includes a first shell 22 and a second shell 23 that cover each other and are sealed to each other.

[0044] The first electrical device 60 refers to an electrical device disposed in the sealed cabin 20. The sealed cabin 20 can seal and isolate the first electrical device 60 therein, so as to realize partition protection and enhanced protection of this part of the first electrical device 60, thereby reducing the risk of failure and damage of this part of the first electrical device 60 due to the influence of the humid environment, and improving the reliability and service life of the water surface cleaning device. One or more first electrical devices 60 can be arranged in the sealed cabin 20. In the case where multiple first electrical devices 60 are arranged in the sealed cabin 20, the types of each first electrical device 60 can be arranged in the same or different. The first electrical device 60 can be an electrical device that is susceptible to the influence of the humid environment, for example, it can be a power supply 60a (such as a battery), a circuit board 60b (such as a PCB (Printed Circuit Board, printed circuit board) board, a flexible circuit board, etc.), an NFC (Near Field Communication, near field communication) antenna, etc. Among them, the electrical connector 30 and the corresponding first electrical device 60 can be directly electrically connected, or can be indirectly electrically connected by other components (such as conductive cables).

[0045] The second electrical device 70 refers to an electrical device disposed outside the sealed cabin 20. The second electrical device 70 may be disposed outside the sealed cabin 20 and inside the housing 10, or may be disposed outside the housing 10. There may be one or more second electrical devices 70. In the case where there are multiple second electrical devices 70, the types of the second electrical devices 70 may be the same or different. The second electrical device 70 may be an electrical device that is not easily affected by a humid environment, such as a propeller motor, an ultrasonic sensor, a display light, a button, a waterproof motor, a solar panel 70a, and the like. The electrical connector 30 may be directly electrically connected to the corresponding second electrical device 70, or may be indirectly electrically connected via other components (such as a conductive cable).

[0046] It should also be noted that the electrical connector 30 is disposed in the sealed cabin 20, that is, the electrical connector 30 may be partially disposed in the sealed cabin 20 and partially disposed outside the sealed cabin 20; or, the electrical connector 30 may be entirely disposed in the sealed cabin 20; or, the electrical connector 30 may be entirely disposed outside the sealed cabin 20. For example, Figure 5 As shown, the male connector 31 of the electrical connector 30 is embedded in the wall of the sealed cabin 20 , and the female connector 32 of the electrical connector 30 is located outside the sealed cabin 20 .

[0047] The electrical connector 30 is used to establish a required electrical connection relationship between the first electrical device 60 disposed in the sealed cabin 20 and the second electrical device 70 disposed outside the sealed cabin 20 as needed.

[0048] The electrical connector 30 includes a matching male connector 31 and a female connector 32. The male connector 31 is plugged into the female connector 32. When the female connector 32 is tightly plugged into the male connector 31, the female connector 32 and the male connector 31 can be reliably electrically connected, so that the corresponding first electrical device 60 and the second electrical device 70 can be quickly and reliably connected via the electrical connector 30.

[0049] The female connector 32 can move in a direction close to or away from the male connector 31, and during the axial movement of the female connector 32 relative to the male connector 31, the female connector 32 and the male connector 31 maintain a plug-in relationship, that is, the female connector 32 is not disassembled and does not separate from the male connector 31. Based on this, in some scenarios where the electrical connection between them needs to be temporarily disconnected (such as inspection scenarios and later maintenance scenarios), the female connector 32 can be moved in a direction away from the male connector 31 while maintaining the plug-in relationship between the female connector 32 and the male connector 31, so that the plug-in between the female connector 32 and the male connector 31 is loosened, and the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical component 60 and the second electrical component 70 are quickly disconnected. Since the female connector 32 and the male connector 31 are kept plugged in, in the subsequent scenes, the female connector 32 can be directly moved in the direction close to the male connector 31, so that the female connector 32 and the male connector 31 can be quickly restored to close plugging, and the electrical connection between the female connector 32 and the male connector 31, and the electrical connection between the corresponding first electrical device 60 and the second electrical device 70 can be quickly restored, without the need to perform the action of "realigning and re-plugging the female connector 32 and the male connector 31". Among them, the female connector 32 can be arranged on the side of the male connector 31 close to the outside of the sealed cabin 20, so as to facilitate the operation of moving the female connector 32.

[0050] The embodiment of the present application provides a water surface cleaning device, which can quickly and reliably establish an electrical connection between a first electrical device 60 built in a sealed cabin 20 and a second electrical device 70 arranged outside the sealed cabin 20 through the tight plugging of the electrical connector 30, the male connector 31 and the female connector 32 that are plugged in and adapted to be plugged in. In addition, in some scenarios where the electrical connection needs to be temporarily disconnected, the female connector 32 can be moved in a direction away from the male connector 31 while maintaining the plugging with the male connector 31, so as to quickly disconnect the electrical connection between the female connector 32 and the male connector 31, and the corresponding electrical connection between the first electrical device 60 and the second electrical device 70; in the subsequent scenarios, since the female connector 32 and the male connector 31 are maintained plugged in, the female connector 32 can be directly moved in a direction close to the male connector 31, so as to quickly restore the electrical connection between the female connector 32 and the male connector 31, and the corresponding electrical connection between the first electrical device 60 and the second electrical device 70, without the need to perform the action of "realigning and re-plugging the female connector 32 and the male connector 31". Therefore, the water surface cleaning device can effectively improve the connection convenience, connection reliability and disconnection convenience of the electrical connection between the first electrical component 60 arranged in the sealed cabin 20 and the second electrical component 70 arranged outside the sealed cabin 20 based on the electrical connector 30.

[0051] See also Figure 2 , Figure 3 , Figure 5 In some embodiments of the present application, at least a portion of the male connector 31 is elastic (ie, a portion or all of the male connector 31 is elastic), and the male connector 31 is elastically plugged into the female connector 32.

[0052] By adopting the above-mentioned scheme, when the female connector 32 is plugged into and matched with the male connector 31, and the female connector 32 moves in a direction close to the male connector 31, so that the male connector 31 is elastically deformed and generates elastic force to rebound against the female connector 32, the female connector 32 and the male connector 31 can form a tight fit based on elasticity and elastic force, and can form a stable and reliable electrical connection, thereby improving the connection reliability and convenience of the electrical connection between the female connector 32 and the male connector 31, and the electrical connection between the corresponding first electrical device 60 and the second electrical device 70. On the contrary, when the female connector 32 is plugged into the male connector 31 and the female connector 32 moves in a direction away from the male connector 31, so that the male connector 31 recovers its elastic deformation (i.e., no elastic deformation and elastic force are generated), the plugging tightness between the female connector 32 and the male connector 31 is relatively loose, and the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical component 60 and the second electrical component 70 can be quickly disconnected, thereby improving the convenience of disconnecting the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical component 60 and the second electrical component 70.

[0053] Of course, in other embodiments, at least a portion of the female connector 32 may be made elastic.

[0054] See also Figure 3 , Figure 4 , Figure 5 In some embodiments of the present application, the male connector 31 includes a conductive seat 311 and a conductive needle 312 arranged in sequence along a direction close to the female connector 32, and a mounting hole 3111 is provided on the side of the conductive seat 311 facing the conductive needle 312, a portion of the conductive needle 312 is installed in the mounting hole 3111 and another portion of the conductive needle 312 is exposed outside the mounting hole 3111, and a plug-in hole 321 is provided on the side of the female connector 32 facing the male connector 31, and the conductive needle 312 is plugged into the plug-in hole 321.

[0055] It should be noted that the conductive seat 311 and the conductive pin 312 are sequentially arranged in a direction close to the female connector 32. The conductive pin 312 is made of a conductive material (such as a metal material) and has conductivity. The conductive seat 311 is made of a conductive material (such as a metal material) and also has conductivity. The conductive seat 311 and the conductive pin 312 are sequentially electrically connected.

[0056] The conductive seat 311 and the conductive needle 312 are formed separately. A mounting hole 3111 is provided on the side of the conductive seat 311 facing the conductive needle 312, and the conductive needle 312 is mounted in the mounting hole 3111, and a part of the conductive needle 312 is exposed outside the mounting hole 3111. The conductive needle 312 can be fixed relative to the conductive seat 311, or can be movably arranged relative to the conductive seat 311. The mounting hole 3111 can be in a variety of shapes, for example, the mounting hole 3111 can be a circular hole, a rectangular hole, etc. The cross-sectional size of the mounting hole 3111 can be greater than, equal to, or less than the cross-sectional size of the conductive needle 312, depending on the coordination requirements of the electrical connection and mechanical connection between the conductive seat 311 and the conductive needle 312, and the "cross-section" refers to the cross-section of the corresponding structure perpendicular to the central axis.

[0057] The female connector 32 is provided with a plug hole 321 on one side facing the male connector 31. The shape and size of the plug hole 321 are designed corresponding to the conductive pin 312. The conductive pin 312 can be plugged into the plug hole 321. When the conductive pin 312 is plugged into the plug hole 321 and the female connector 32 moves in a direction close to the male connector 31 so that the conductive pin 312 and the plug hole 321 are tightly matched, a stable and reliable electrical connection can be formed between the conductive pin 312 and the plug hole 321, so that the female connector 32 and the male connector 31 are reliably electrically connected. On the contrary, when the conductive pin 312 is plugged into the plug hole 321 and the female connector 32 moves in a direction away from the male connector 31 so that the conductive pin 312 and the plug hole 321 are loosely matched, the conductive pin 312 and the female connector 32 can be electrically disconnected, so that the female connector 32 and the male connector 31 can be electrically disconnected.

[0058] By adopting the above scheme, the male connector 31 can be conveniently, quickly and reliably assembled by first separately forming the conductive seat 311 and the conductive pin 312, and then installing the conductive pin 312 in the installation hole 3111 of the conductive seat 311, thereby simplifying and optimizing the structure of the male connector 31, and improving the assembly convenience and structural reliability of the male connector 31. It is also convenient for the male connector 31 to be plugged and matched with the plug hole 321 of the female connector 32 through the conductive pin 312, thereby improving the connection convenience, connection reliability and disconnection convenience of the electrical connection between the male connector 31 and the female connector 32.

[0059] Of course, in other embodiments, the male connector 31 and the female connector 32 may adopt other structural designs to achieve mutual plug-in cooperation.

[0060] See also Figure 2 , Figure 3 , Figure 5In some embodiments of the present application, the conductive needle 312 can be movably mounted in the mounting hole 3111, and the male connector 31 also includes an elastic member 313, which is accommodated in the mounting hole 3111, and the elastic member 313 is elastically connected between the conductive needle 312 and the bottom of the mounting hole 3111.

[0061] It should be noted that the conductive needle 312 can be movably arranged along the axial direction of the mounting hole 3111, that is, the conductive needle 312 can be movably arranged relative to the conductive seat 311. On this basis, the male connector 31 can be provided with an elastic member 313 at the end side of the conductive needle 312 located in the mounting hole 3111, and the end of the elastic member 313 away from the conductive needle 312 can be elastically connected to the bottom of the mounting hole 3111. Among them, the elastic member 313 can be but not limited to a spring, etc. Among them, the elastic member 313 can be made of a conductive material, so that the conductive needle 312 can be electrically connected to both the elastic member 313 and the conductive seat 311, thereby improving the reliability of the electrical connection. Of course, the elastic member 313 can also be made of an insulating material.

[0062] By adopting the above scheme, the male connector 31 can make the conductive pin 312 movably arranged relative to the conductive seat 311, and elastically connected between the conductive pin 312 and the bottom of the mounting hole 3111 through the elastic member 313, so that based on the elasticity of the elastic member 313, the relative position of the conductive pin 312 relative to the conductive seat 311 can automatically adjust to the fit between the conductive pin 312 and the plug hole 321, so that the end of the conductive pin 312 away from the elastic member 313 can be elastically plugged into the plug hole 321.

[0063] Based on this, when the conductive pin 312 is plugged into the plug hole 321 and the female connector 32 moves in a direction close to the male connector 31, the elastic member 313 generates elastic deformation and elastic force to cause the conductive pin 312 to fit tightly with the plug hole 321. A stable and reliable electrical connection can be formed between the conductive pin 312 and the plug hole 321, so that the female connector 32 and the male connector 31 can establish a stable and reliable electrical connection, which can improve the connection reliability and convenience of the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical device 60 and the second electrical device 70.

[0064] On the contrary, when the conductive pin 312 is plugged into the plug hole 321 and the female connector 32 moves in a direction away from the male connector 31, the elastic member 313 recovers its elastic deformation and generates no elastic force, thereby making the plugging tightness of the conductive pin 312 and the plug hole 321 relatively loose. In this case, the electrical connection between the conductive pin 312 and the plug hole 321 can be disconnected, thereby making it possible to disconnect the electrical connection between the female connector 32 and the male connector 31 and the electrical connection between the corresponding first electrical component 60 and the second electrical component 70. This can improve the convenience of disconnecting the electrical connection between the female connector 32 and the male connector 31 and the electrical connection between the corresponding first electrical component 60 and the second electrical component 70.

[0065] See also Figure 2 , Figure 3 , Figure 5 In some embodiments of the present application, the conductive pin 312 is an elastic conductive pin.

[0066] It should be noted that the conductive pin 312 is an elastic conductive pin, that is, it has elasticity and conductivity. The conductive pin 312 can be made elastic through material design or structural design. For example, the conductive pin 312 can be made of an elastic conductive material. For another example, the conductive pin 312 can be made of a conductive material and an elastic structure such as a spring or an elastic contact pin is provided at one end of the conductive pin 312 away from the conductive seat 311.

[0067] By adopting the above scheme, the male connector 31 can make the conductive pin 312 elastically plugged into the plug hole 321 through the elasticity of the conductive pin 312 itself. Based on this, when the conductive pin 312 is plugged into the plug hole 321 and the female connector 32 moves in a direction close to the male connector 31, so that the conductive pin 312 generates elastic deformation and elastic force to promote the conductive pin 312 to fit tightly with the plug hole 321, a stable and reliable electrical connection can be formed between the conductive pin 312 and the plug hole 321, so that the female connector 32 and the male connector 31 can establish a stable and reliable electrical connection, which can improve the connection reliability and connection convenience of the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical device 60 and the second electrical device 70. On the contrary, when the conductive pin 312 is plugged into the plug hole 321 and the female connector 32 moves in a direction away from the male connector 31, the conductive pin 312 recovers its elastic deformation and does not generate elastic force, and the plugging tightness between the conductive pin 312 and the plug hole 321 is relatively loose, the electrical connection between the conductive pin 312 and the plug hole 321 can be disconnected, thereby disconnecting the electrical connection between the female connector 32 and the male connector 31, and improving the convenience of disconnecting the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical component 60 and the second electrical component 70.

[0068] See also Figure 2 , Figure 3 , Figure 5 In some embodiments of the present application, the conductive seat 311 is an elastic conductive seat.

[0069] It should be noted that the conductive seat 311 is an elastic conductive seat, that is, it has elasticity and conductivity. The conductive seat 311 can be made elastic through material design or structural design. For example, the conductive seat 311 can be made of an elastic conductive material. For another example, the conductive seat 311 can be made of a conductive material and an elastic structure such as a spring or an elastic contact pin is provided at one end of the conductive seat 311 away from the conductive needle 312.

[0070] By adopting the above scheme, the male connector 31 can make the conductive pin 312 be elastically plugged into the plug hole 321 through the elasticity of the conductive seat 311 itself. Based on this, when the conductive pin 312 is plugged into the plug hole 321 and the female connector 32 moves in a direction close to the male connector 31, so that the conductive seat 311 generates elastic deformation and elastic force to promote the conductive pin 312 to fit tightly with the plug hole 321, a stable and reliable electrical connection can be formed between the conductive pin 312 and the plug hole 321, so that the female connector 32 and the male connector 31 can establish a stable and reliable electrical connection, which can improve the connection reliability and connection convenience of the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical device 60 and the second electrical device 70. On the contrary, when the conductive pin 312 is plugged into the plug hole 321 and the female connector 32 moves in a direction away from the male connector 31, the conductive seat 311 restores its elastic deformation and does not generate elastic force, and the plugging tightness between the conductive pin 312 and the plug hole 321 is relatively loose, the electrical connection between the conductive pin 312 and the plug hole 321 can be disconnected, thereby disconnecting the electrical connection between the female connector 32 and the male connector 31, and improving the convenience of disconnecting the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical component 60 and the second electrical component 70.

[0071] It should be noted that the means of “setting an elastic member 313 ”, “the conductive needle 312 being an elastic conductive needle” and “the conductive seat 311 being an elastic conductive seat” can be set independently or in combination, and can be set specifically according to the elastic strength required by the male connector 31 .

[0072] See also Figure 2 , Figure 3 , Figure 5 In some embodiments of the present application, the sealed cabin 20 is provided with an outlet structure 21, and a first through-hole 211 is provided in the area enclosed by the outlet structure 21. The electrical connector 30 is passed through the first through-hole 211, and the electrical connector 30 and the first through-hole 211 are sealed and connected.

[0073] It should be noted that the sealed cabin 20 is provided with an outlet structure 21. The outlet structure 21 can be provided on any side of the sealed cabin 20, for example, on one side of the sealed cabin 20 along the circumferential direction. There can be one or more outlet structures 21. In the case where there are multiple outlet structures 21, the structures of the multiple outlet structures 21 can be arranged in the same or different manners, and the multiple outlet structures 21 can be arranged on different sides of the sealed cabin 20 or on the same side of the sealed cabin 20.

[0074] The outlet structure 21 can be a protruding structure or a recessed structure. The area enclosed by the outlet structure 21 is planned as the outlet area of ​​the electrical connector 30. A first through-hole 211 is provided in the area enclosed by the outlet structure 21. The first through-hole 211 passes through the inside and outside of the sealed cabin 20. The first through-hole 211 can be provided for an electrical connector 30 to pass through. The electrical connector 30 can have its male connector 31 passed through the first through-hole 211, or its female connector 32 passed through the first through-hole 211, or other parts thereof (such as a conductive cable) passed through the first through-hole 211.

[0075] The hole wall of the first through hole 211 is sealedly connected to the corresponding electrical connector 30, and the sealed connection can be achieved by, but not limited to, a sealing ring, a sealant, an interference fit, etc. In particular, when the electrical connector 30 has its female connector 32 inserted through the first through hole 211, in order to facilitate the movement of the female connector 32, the first through hole 211 and the female connector 32 can be sealedly connected by a sealing ring or an interference fit, etc., which do not completely restrict the movement of the female connector 32.

[0076] By adopting the above scheme, the sealed cabin 20 can enclose a specific area and set the first perforation 211 through the outlet structure 21, thereby providing a clear path and area for the electric connector 30 to pass out. Based on this, the electric connector 30 can be orderly passed out of the sealed cabin 20 along the preset path, and the layout planning of the electric connector 30 can be reasonable and regular, which can reduce the disorderly layout, thereby optimizing and modularizing the structure of the sealed cabin 20, and improving the overall aesthetics and maintainability. On this basis, by making the hole wall of the first perforation 211 and the corresponding electric connector 30 sealed and connected, it can effectively prevent moisture and humidity from penetrating into the sealed cabin 20 along the gap between the first perforation 211 and the corresponding electric connector 30, thereby maintaining the sealing of the sealed cabin 20, maintaining the sealing isolation and partition protection of the sealed cabin 20 for the first electrical device 60, reducing the risk of failure and damage of the first electrical device 60 due to the humid environment, and improving the reliability and service life of the water surface cleaning device.

[0077] Of course, in other embodiments, the sealed cabin 20 may directly be provided with the first through hole 211 through which the power connector 30 passes, and the wire outlet structure 21 may be omitted.

[0078] See also Figure 2 , Figure 3 , Figure 5 In some embodiments of the present application, the water surface cleaning device includes a bracket 40 sealed and docked with the outlet structure 21, the bracket 40 is provided with a second perforation 41 corresponding to the first perforation 211 one by one, the electrical connector 30 is penetrated in the corresponding first perforation 211 and the second perforation 41, and the electrical connector 30 is sealedly connected to the second perforation 41.

[0079] It should be noted that, when the sealed cabin 20 is provided with the outlet structure 21, a bracket 40 corresponding to the outlet structure 21 may be additionally provided. That is, the number and position of the bracket 40 correspond to the number and position of the outlet structure 21. The bracket 40 is sealed and docked with the outlet structure 21 one by one, so as to enclose a sealed space 44 therebetween.

[0080] The bracket 40 is provided with a second through hole 41, which is arranged one-to-one with the first through hole 211, and the second through hole 41 passes through the corresponding wall of the bracket 40. The electrical connector 30 is provided in the corresponding first through hole 211 and the second through hole 41. For example, the electrical connector 30 can have its male connector 31 provided in the first through hole 211 and its female connector 32 provided in the second through hole 41. For another example, the electrical connector 30 can have its male connector 31 provided in the first through hole 211 and the second through hole 41 and its female connector 32 is located outside the second through hole 41. For another example, the electrical connector 30 can have its female end provided in the first through hole 211 and the second through hole 41 and its male connector 31 is located inside the first through hole 211. For another example, the electrical connector 30 can have other parts (such as a conductive cable) provided in the first through hole 211 or the second through hole 41.

[0081] The hole wall of the second through hole 41 is sealed with the corresponding electrical connector 30, and the sealed connection can be achieved by, but not limited to, a sealing ring, a sealant, an interference fit, etc. In particular, when the electrical connector 30 has its female connector 32 inserted through the second through hole 41, in order to facilitate the movement of the female connector 32, the second through hole 41 and the female connector 32 can be sealed by a sealing ring or an interference fit, etc., which do not completely restrict the movement of the female connector 32.

[0082] By adopting the above scheme, a specific area can be enclosed by the bracket 40 and a second perforation 41 can be set to provide a clear path and area for the installation of the electrical connector 30. Based on this, the electrical connector 30 can be orderly approached to the output line structure 21 along the preset path, and the layout planning of the electrical connector 30 can be reasonable and regular, which can reduce the disorderly layout, thereby optimizing and regularizing the structure of the water surface cleaning device and improving the overall aesthetics and maintainability.

[0083] On this basis, by sealingly docking the bracket 40 with the outlet structure 21 and sealingly connecting the hole wall of the second perforation 41 with the corresponding electrical connector 30, multiple sealing barriers can be formed between the second perforation 41 and the corresponding electrical connector 30, between the bracket 40 and the outlet structure 21, and between the first perforation 211 and the corresponding electrical connector 30, which can effectively prevent water and moisture from penetrating into the sealed space 44 and the sealed cabin 20 along the gap between the second perforation 41 and the corresponding electrical connector 30, the gap between the outlet structure 21 and the bracket 40, and the gap between the first perforation 211 and the corresponding electrical connector 30, thereby maintaining the sealing of the sealed space 44 and the sealed cabin 20, maintaining the sealing isolation and partition protection of the sealed space 44 for the electrical connector 30, and maintaining the sealing isolation and partition protection of the sealed cabin 20 for the first electrical device 60, thereby reducing the risk of failure and damage of the first electrical device 60 and the electrical connector 30 due to the humid environment, and improving the reliability and service life of the water surface cleaning device.

[0084] In addition, the bracket 40 can provide a stable support for the electrical connector 30 to reduce the risk of loosening or damage of the electrical connection due to vibration or external force. Thus, the stability, reliability and safety of the electrical connection formed by the electrical connector 30 can be improved, and the reliability and service life of the water surface cleaning device can be improved.

[0085] In some embodiments, on the basis of the sealed connection between the bracket 40 and the outlet structure 21, the bracket 40 may also be connected and fixed to the sealed cabin 20, and the connection and fixing method may be but is not limited to screw connection.

[0086] Of course, in other embodiments, the male connector 31 and the female connector 32 of the electrical connector 30 may be electrically connected directly outside the sealed cabin 20 , and the bracket 40 may be omitted.

[0087] See also Figure 3 , Figure 4 , Figure 5 In some embodiments of the present application, a first annular groove 42 is provided on one side of the bracket 40 facing the wire-out structure 21 . The wire-out structure 21 is arranged in an annular shape. The wire-out structure 21 is inserted into the first annular groove 42 and is sealed and connected to the first annular groove 42 .

The outlet structure 21 and the first annular groove 42 can be sealed and connected by, but not limited to, a sealing ring, a sealant, an interference fit, and the like.

[0089] By adopting the above scheme, the corresponding outlet structure 21 and the bracket 40 can be conveniently, quickly and reliably sealed and connected between the outlet structure 21 and the bracket 40 by inserting the annular outlet structure 21 into the first annular groove 42 of the bracket 40 and sealingly connecting the outlet structure 21 and the first annular groove 42. Based on this, the connection convenience, connection reliability and connection stability of the sealed docking between the outlet structure 21 and the bracket 40 can be improved. In addition, the contact area between the outlet structure 21 and the first annular groove 42 is large, and the sealing material (such as a sealing ring, a sealant, etc.) can be used to promote the formation of a tight sealing effect between the outlet structure 21 and the bracket 40, which can effectively prevent water and moisture from penetrating into the sealed space 44 along the gap between the outlet structure 21 and the first annular groove 42.

[0090] See also Figure 3 , Figure 4 , Figure 5 In some embodiments of the present application, a first sealing ring 50 is provided between the bottom of the first annular groove 42 and the lead-out structure 21 .

[0091] It should be noted that the first sealing ring 50 is annular and is disposed in the first annular groove 42. The first sealing ring 50 is sealed between the groove bottom of the first annular groove 42 and the outlet structure 21.

[0092] By adopting the above solution, when the annular outlet structure 21 is inserted into the first annular groove 42 of the bracket 40, a sealed connection can be formed between the groove bottom of the first annular groove 42 and the outlet structure 21 via the first sealing ring 50.

The abutment of the second ring portion 43 and the first ring portion 212 can be sealed and connected by, but not limited to, a sealing ring, a sealant, etc.

[0096] By adopting the above solution, the corresponding outlet structure 21 and the bracket 40 can be conveniently, quickly and reliably sealed and connected by making the first ring portion 212 of the outlet structure 21 abut against and seal the second ring portion 43 of the bracket 40. Based on this, the connection convenience, connection reliability, connection stability and sealing performance of the sealed butt connection between the outlet structure 21 and the bracket 40 can be improved, and water and moisture can be effectively prevented from penetrating into the sealed space 44 along the gap between the first ring portion 212 and the second ring portion 43.

[0097] In some embodiments, the outlet structure 21 and the bracket 40 are each provided with one. In this case, the corresponding outlet structure 21 and the bracket 40 can adopt the method of "the annular outlet structure 21 is inserted into the first annular groove 42 of the bracket 40 and is sealed with the first annular groove 42", or the method of "the first ring portion 212 of the outlet structure 21 is directly abutted with the second ring portion 43 of the bracket 40 and is sealed" to achieve sealed docking. That is, the embodiment of "the annular outlet structure 21 is inserted into the first annular groove 42 of the bracket 40 and is sealed with the first annular groove 42" and the embodiment of "the first ring portion 212 of the outlet structure 21 is directly abutted with the second ring portion 43 of the bracket 40 and is sealed" can be selected.

[0098] In another embodiment, the corresponding outlet structure 21 and bracket 40 are taken as a group, and multiple groups of outlet structures 21 and bracket 40 are provided. Multiple groups of outlet structures 21 and bracket 40 can uniformly adopt the method of "the annular outlet structure 21 is inserted into the first annular groove 42 of the bracket 40 and is sealed and connected to the first annular groove 42" to achieve sealed docking. Or, multiple groups of outlet structures 21 and bracket 40 can uniformly adopt the method of "the first ring portion 212 of the outlet structure 21 is directly abutted and sealedly connected to the second ring portion 43 of the bracket 40" to achieve sealed docking. Or, multiple groups of outlet structures 21 and bracket 40 can partially adopt the method of "the annular outlet structure 21 is inserted into the first annular groove 42 of the bracket 40 and is sealed and connected to the first annular groove 42", and the other part adopts the method of "the first ring portion 212 of the outlet structure 21 is directly abutted and sealedly connected to the second ring portion 43 of the bracket 40" to achieve sealed docking. That is, the embodiment of "the annular wire outlet structure 21 is inserted into the first annular groove 42 of the bracket 40 and is sealed with the first annular groove 42" and the embodiment of "the first ring portion 212 of the wire outlet structure 21 is directly abutted against and sealed with the second ring portion 43 of the bracket 40" can be selected or can be compatible.

[0099] Of course, in other embodiments, the corresponding outlet structure 21 and the bracket 40 may be sealed and connected in other ways.

[0100] See also Figure 3 , Figure 4 , Figure 5 In some embodiments of the present application, the outgoing line structure 21 includes a third ring portion 213 , which surrounds the outer circumference of the first ring portion 212 and is spaced apart from the first ring portion 212 .

[0101] It should be noted that the wire outlet structure 21 may be provided with an annular third ring portion 213. The third ring portion 213 surrounds the outer circumference of the first ring portion 212. The inner circumference of the third ring portion 213 is spaced from the outer circumference of the first ring portion 212, and together they enclose a second annular groove 214.

[0102] By adopting the above scheme, the outlet structure 21 can be provided with a third ring portion 213 around the outer periphery of the first ring portion 212, and the third ring portion 213 and the first ring portion 212 are enclosed to form a second annular groove 214, so as to limit and accommodate the sealing material (such as a sealing ring, a sealant, etc.) between the first ring portion 212 and the second ring portion 43 via the second annular groove 214. Based on this, the sealing material can be tightly fitted to the abutment between the first ring portion 212 and the second ring portion 43, which can facilitate the formation of an almost impeccable sealing barrier, thereby improving the connection convenience, connection reliability, and sealing performance of the sealed connection between the first ring portion 212 and the second ring portion 43, and effectively preventing water and moisture from penetrating into the sealed space 44 along the gap between the first ring portion 212 and the second ring portion 43.

[0103] Of course, in other embodiments, the sealing process may be performed directly at the abutment between the first ring portion 212 and the second ring portion 43 , and the third ring portion 213 may be omitted.

[0104] See also Figure 3 , Figure 4 , Figure 5 In some embodiments of the present application, the third ring portion 213 protrudes from the abutment between the first ring portion 212 and the second ring portion 43 .

[0105] By adopting the above solution, by making the third ring portion 213 protrude from the abutment between the first ring portion 212 and the second ring portion 43, the notch of the second annular groove 214 formed by the third ring portion 213 and the first ring portion 212 can exceed the abutment between the first ring portion 212 and the second ring portion 43. Based on this, the sealing material limitedly accommodated in the second annular groove 214 can cover the abutment between the first ring portion 212 and the second ring portion 43, and a reliable and comprehensive sealing effect is formed on the abutment between the first ring portion 212 and the second ring portion 43, thereby improving the sealing between the first ring portion 212 and the second ring portion 43, and effectively preventing water and moisture from penetrating into the sealed space 44 along the gap between the first ring portion 212 and the second ring portion 43.

[0106] Of course, in other embodiments, the third ring portion 213 may be flush with or lower than the abutment point between the first ring portion 212 and the second ring portion 43 .

[0107] See also Figure 2 , Figure 3 , Figure 5 In some embodiments of the present application, the plug-in point of the male connector 31 and the female connector 32 is located in the enclosed space of the outlet structure 21 and the bracket 40.

[0108] It should be noted that the plug-in mating portion of the male connector 31 and the female connector 32 is located in a sealed space 44 formed by the bracket 40 and the outlet structure 21. Figure 5 As shown, in some embodiments, the male connector 31 is inserted into the first through hole 211, the female connector 32 is inserted into the second through hole 41, and the plug-in portion of the male connector 31 and the female connector 32 is located in a sealed space 44 enclosed by the bracket 40 and the outlet structure 21. Of course, in other embodiments, the male connector 31 may be located as a whole in the sealed space 44 enclosed by the bracket 40 and the outlet structure 21, or the female connector 32 may be located as a whole in the sealed space 44 enclosed by the bracket 40 and the outlet structure 21.

[0109] By adopting the above scheme, the plug-in and mating parts of the male connector 31 and the female connector 32 can be placed in the sealed space 44 formed by the bracket 40 and the outlet structure 21. Based on this, the sealed connection between the second perforation 41 and the corresponding electrical connector 30 and the sealed connection between the bracket 40 and the outlet structure 21 can be utilized to form a double sealing barrier for the plug-in and mating parts of the male connector 31 and the female connector 32, which can effectively prevent water and moisture from penetrating into the sealed space 44 along the gap between the second perforation 41 and the corresponding electrical connector 30 and the gap between the outlet structure 21 and the bracket 40, and can effectively reduce the risk of the electrical connection between the male connector 31 and the female connector 32 being affected by water and moisture, thereby improving the stability, reliability and safety of the electrical connection between the female connector 32 and the male connector 31 and the corresponding electrical connection between the first electrical device 60 and the second electrical device 70, and can improve the reliability and service life of the water surface cleaning device.

[0110] See also Figure 2 , Figure 5 In some embodiments of the present application, two outlet structures 21 are provided, and the two outlet structures 21 are disposed on opposite sides of the sealed cabin 20 .

[0111] By adopting the above solution, the sealed cabin 20 can be provided with outlet structures 21 on opposite sides thereof, so as to provide different areas and paths for the electrical connector 30 to pass through. Based on this, it is convenient to partition and layout the electrical connector 30 according to the layout of the first electrical device 60, the electrical connection requirements of the first electrical device 60, the electrical connection polarity, etc., so as to improve the layout flexibility of the electrical connector 30 and reduce the electromagnetic interference and physical interference between the electrical connectors 30. In addition, the design of two outlet structures 21 being arranged on opposite sides of the sealed cabin 20 can make the structural layout of the sealed cabin 20 balanced, optimize the structure of the sealed cabin 20, and improve the structural stability and aesthetics of the sealed cabin 20.

[0112] In some embodiments, the specific structures of the two outlet structures 21 can be set differently to improve the foolproof effect and reduce the risk of layout and insertion errors of the electrical connector 30. Figure 5 As shown, in some embodiments, one of the two outgoing wire structures 21 is arranged in a ring shape, and the other of the two outgoing wire structures 21 includes a first ring portion 212 and a third ring portion 213 surrounding the outer circumference of the first ring portion 212 .
