[0002] As people's living standards improve, swimming pools have become a popular recreational venue for people seeking a higher quality of life. Whether it is a private or public swimming pool, the cleanliness of the pool water is the primary concern for people.

[0003] Most existing cleaning robots use end-face sealing for their sealed compartments. This means that the seal is placed between the end face of the end cap and the compartment body. It requires continuous pressure to be applied to the end cap towards the compartment body to compress the seal and achieve a sealing effect. This not only results in high resistance to disassembly and assembly, requiring multiple fasteners to lock the end cap onto the compartment body, but also makes it difficult to control the sealing effect, as the sealing performance of the seal is related to the compression state of the end cap.

Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] like Figure 1 and Figure 2 As shown, according to a first aspect of this application, this application provides a sealed chamber 100 for a cleaning robot. The sealed chamber 100 is located inside the body of the cleaning robot and is used to seal the electronic components 40 housed within the sealed chamber 100, effectively protecting the electronic components 40 inside the cleaning robot. The sealed chamber 100 includes a chamber body 10 and an end cap 20. An installation cavity 11 is formed inside the chamber body 10, and the electronic components 40 are disposed within the installation cavity 11. The end cap 20 is fitted onto the open end of the installation cavity 11 to seal the open end of the installation cavity 11, thereby forming a sealed space within the installation cavity 11 to prevent external liquids and dust contaminants from entering, thus effectively protecting the electronic components 40 inside the installation cavity 11.

[0044] In this embodiment, the sealed chamber 100 further includes a first sealing assembly 30. The end cap 20 has a protrusion 21 extending toward the bottom of the chamber 10 and located within the chamber 10, with a gap between the protrusion 21 and the chamber 10. The first sealing assembly 30 is disposed on the chamber 10 or the protrusion 21 and is tightly fitted within the gap between the protrusion 21 and the chamber 10 to provide a circumferential seal at the connection between the end cap 20 and the chamber 10, preventing external liquids from penetrating into the chamber 10 and affecting the electronic components 40 in the mounting cavity 11, such as causing short circuits or corrosion, thereby protecting the electronic components 40 in the mounting cavity 11.

[0045] After adopting the above technical solution, since the first sealing component 30 is located in the gap between the protrusion 21 and the housing 10, it can not only effectively ensure the sealing performance of the first sealing component 30 at the connection between the end cap 20 and the housing 10, so that the sealing performance of the sealing chamber 100 is not affected by the pressing state of the end cap 20; at the same time, it can also improve the assembly efficiency of the sealing chamber 100, without needing to apply pressure to the end cap 20 to deform the first sealing component 30, and without worrying about the end cap 20 shifting during the tightening process and causing sealing failure, or the end cap 20 loosening and affecting the sealing performance of the first sealing component 30, thus ensuring the sealing performance of the first sealing component 30 and preventing external liquid from seeping into the mounting cavity 11 and affecting the electronic component 40.

[0046] In one alternative implementation, such as Figures 2 to 4 As shown, the outer side wall of the protrusion 21 is provided with at least one first mounting groove 211. A portion of the first sealing assembly 30 is embedded in the first mounting groove 211, and another portion of the first sealing assembly 30 extends from the first mounting groove 211 toward the inner side wall of the mounting cavity 11 and abuts against the inner side wall of the mounting cavity 11, so that the first sealing assembly 30 can be compressed by both to achieve radial sealing of the chamber 10, thereby sealing the connection between the end cap 20 and the chamber 10 and preventing external liquid from entering the mounting cavity 11.

[0047] It should be noted that the seal can also be embedded in the inner wall of the mounting cavity 11 and abut against the outer wall of the protrusion 21, so that the first sealing assembly 30 can be compressed by both to achieve radial sealing of the cabin 10. This application does not limit this.

[0048] In an optional embodiment, the first sealing assembly 30 includes a first sealing element 31 and a second sealing element 32, and the first mounting groove 211 includes a first annular groove 2111 and a second annular groove 2112. The first annular groove 2111 and the second annular groove 2112 are arranged sequentially along the disassembly direction of the end cover 20. The first sealing element 31 and the second sealing element 32 are respectively installed on the first annular groove 2111 and the second annular groove 2112 and abut against the inner sidewall of the mounting cavity 11 to achieve a double seal between the end cover 20 and the chamber 10. This makes the sealing performance between the end cover 20 and the chamber 10 more stable and improves the sealing quality of the sealing chamber 100. It can prevent the sealing performance of the sealing chamber 100 from being affected by the failure of one of the first sealing element 31 and the second sealing element 32 during the disassembly and assembly process.

[0049] In one alternative implementation, such as Figure 2 and Figure 3As shown, the first sealing assembly 30 includes a sealing ring body 33 and a sealing lip 34. The sealing lip 34 extends outward from the sealing ring body 33. The sealing ring body 33 is mounted on the protrusion 21. The sealing lip 34 abuts against the inner wall of the mounting cavity 11 to seal the gap between the protrusion 21 and the mounting cavity 11, preventing external liquid from entering the mounting cavity 11 from the connection between the end cap 20 and the chamber 10. At least two sealing lips 34 are provided at intervals on the sealing ring body 33 to enhance the sealing effect and achieve multi-layer sealing.

[0050] In an alternative embodiment, the length of the outward extension of at least two sealing lips 34 increases in the disassembly direction toward the end cap 20. This arrangement allows for smoother installation of the end cap 20 into the housing 10, i.e., the contact between the first sealing assembly 30 and the inner wall of the mounting cavity 11 increases as the protrusion 21 extends.

[0051] For example, when the end cap 20 is installed to the cabin 10, the inner wall of the mounting cavity 11 first contacts one sealing lip 34, and then as the protrusion 21 moves toward the bottom of the mounting cavity 11, the inner wall of the mounting cavity 11 contacts another sealing lip 34, until the end cap 20 is completely fixed to the cabin 10. The length of the at least two sealing lips 34 extending outward from the bottom of the mounting cavity 11 toward the end cap 20 gradually increases, so that the compression formed by the at least two sealing lips 34 abutting against the inner wall of the mounting cavity 11 gradually increases, so as to ensure the sealing between the end cap 20 and the cabin 10, and also ensure that the installation of the end cap 20 is smoother and more convenient.

[0052] In an optional embodiment, the thickness of at least two sealing lips 34 increases along the disassembly direction toward the end cap 20, making the sealing lip 34 that first contacts the inner wall of the mounting cavity 11 more easily deformable, and thus continues to act on the inner wall of the mounting cavity 11, while the sealing lip 34 that finally contacts the inner wall of the mounting cavity 11 is less easily deformable, so as to ensure a seal when the sealing lip 34 is in place; at the same time, it also facilitates the installation of the end cap 20, making the installation of the end cap 20 smoother, and also ensuring the sealing effect.

[0053] In one alternative embodiment, at least two sealing lips 34 extend obliquely along the sealing ring body 33 in the direction of disassembly toward the end cap 20, making the installation of the end cap 20 smoother and easier.

[0054] For example, the thickness of the sealing lip 34 gradually decreases from the sealing ring body 33 toward the direction away from the sealing ring body 33. This arrangement can improve the strength of the root of the sealing lip 34 and increase the flexibility of the end, so that the end can be better deformed and sealed.

[0055] In an alternative embodiment, the cross-section of the sealing lip 34 can be triangular or trapezoidal, both of which facilitate the installation of the end cap 20 while ensuring a sealing effect.

[0056] In an optional embodiment, the sealing lip 34 includes a first sealing lip 341 and a second sealing lip 342, which are arranged sequentially along the disassembly direction of the end cap 20. The outward extension length of the first sealing lip 341 is greater than that of the second sealing lip 342. If only one sealing lip 34 with a thickness equivalent to twice that of the first sealing lip 341 or the second sealing lip 342 is designed, the overall deformation resistance of the first sealing assembly 30 may increase, thereby affecting the assembly efficiency of the end cap 20. Greater pressure needs to be applied to the end cap 20 to deform the first sealing assembly 30 so that it can be installed into the mounting cavity 11 and move along the inner wall of the mounting cavity 11. At the same time, it can also play a guiding role, so that the end cap 20 can be quickly connected to the cabin 10, and the sealing effect between the end cap 20 and the cabin 10 is also ensured. That is, the sealing lip 34 is divided into a first sealing lip 341 and a second sealing lip 342, which not only has the characteristic of easy deformation, but also ensures the sealing effect between the end cap 20 and the cabin 10.

[0057] In an optional embodiment, the first sealing lip 341 has a first end face 3411 and a second end face 3412, which are respectively disposed on opposite sides of the first sealing lip 341. The first end face 3411 faces the disassembly direction of the end cap 20, and the second end face 3412 faces the installation direction of the end cap 20. The first end face 3411 extends horizontally towards the side away from the sealing ring body 33, while the second end face 3412 is inclined towards the disassembly direction of the end cap 20. This increases the deformation resistance of the housing 10 when it contacts the first sealing lip 341, while also providing adaptive force to the first sealing lip 341, resulting in a more uniform gap between the housing 10 and the end cap 20, and a more uniform compression of the first sealing lip 341, thereby improving the sealing performance of the first sealing assembly 30.

[0058] In an alternative embodiment, the first end face 3411 may also be configured to extend horizontally toward the side away from the sealing ring body 33, and the second end face 3412 may extend horizontally toward the side away from the sealing ring body 33, so that the first end face 3411 and the second end face 3412 can make the first sealing assembly 30 better seal the chamber 10.

[0059] In one alternative implementation, such as Figures 2 to 4As shown, the edge of the cabin 10 near the open end has a first outer edge 12 that protrudes outward, and the end cap 20 has a second outer edge 22 that is circumferentially disposed on the outside of the protrusion 21. The end cap 20 is fixedly connected to the cabin 10 through the cooperation of the second outer edge 22 and the first outer edge, so as to realize the fixed connection between the end cap 20 and the cabin 10.

[0060] In one alternative implementation, such as Figures 6 to 8 As shown, a first limiting part 122 is provided on the first outer edge 12, and a second limiting part 222 is provided on the second outer edge 22. The second limiting part 222 cooperates with the first limiting part 122 to limit the relative position between the end cap 20 and the cabin 10, preventing the end cap 20 from moving relative to the cabin 10 under the elastic action of the first sealing assembly 30, so that the first sealing assembly 30 can be more securely installed in the gap between the protrusion 21 and the cabin 10.

[0061] In an optional embodiment, the first limiting part 122 includes a first limiting post disposed on the first outer edge 12, and the second limiting part 222 includes a first limiting hole disposed on the second outer edge 22. The first limiting post passes through the first limiting hole when the end cover 20 is connected to the cabin 10, so as to realize the positioning and installation between the end cover 20 and the cabin 10.

[0062] In one optional embodiment, a first fixing part 121 is provided on the first outer edge 12, and a second fixing part 221 is provided on the second outer edge 22. The first fixing part 121 and the second fixing part 221 cooperate to fix the end cover 20 on the second outer edge 22, so that the end cover 20 and the cabin 10 can be fixed together.

[0063] In an optional embodiment, the first fixing part 121 includes a first fixing hole 2211 disposed on the first outer edge 12, and the second fixing part 221 includes a second fixing hole disposed on the second outer edge 22 and a first connector 2212 disposed in the second fixing hole. The first connector 2212 is fixedly connected to the first fixing hole 2211. The first connector 2212 can be a screw, and the first fixing hole 2211 can be a threaded hole. The screw passes through the second fixing hole and is threadedly connected to the threaded hole to fix the end cover 20 to the cabin 10.

[0064] In one alternative implementation, such as Figures 2 to 5 As shown, the electronic component 40 includes a water pump motor 41, and the end cover 20 is provided with a first through hole. The output shaft 411 of the water pump motor 41 is fitted with a mounting base 50. The mounting base 50 is installed in the first through hole and a second sealing component 60 is provided between it and the end cover 20. The second sealing component 60 is used to seal the connection between the mounting base 50 and the end cover 20 to prevent external liquid from seeping into the mounting cavity 11 from the connection between the mounting base 50 and the end cover 20.

[0065] In an optional embodiment, the second sealing assembly 60 includes a third seal 61. A third annular groove is provided on the outer side wall of the mounting base 50. The third seal 61 is embedded in the third annular groove and abuts against the inner side wall of the first through hole, so that a better seal can be established between the mounting base 50 and the first through hole, preventing external liquid from seeping into the mounting cavity 11 from the connection between the mounting base 50 and the first through hole.

[0066] In one optional embodiment, the mounting base 50 includes a connecting body 51 and a second connecting member. The output shaft 411 of the water pump motor 41 is rotatably mounted in the connecting body 51, and the connecting body 51 is fixed in the first through hole by the second connecting member. The second connecting member includes, but is not limited to, a nut. The portion of the connecting body 51 extending out of the first through hole has a threaded section, and one end of the connecting body 51 located within the mounting cavity 11 has a first flange. The nut is threadedly connected to the threaded section, causing the first flange to abut against the inner wall of the mounting cavity 11, thereby fixing the connecting body 51 in the first through hole.

[0067] In one optional embodiment, the connecting seat 51 includes a first cylindrical body, a first flange circumferentially disposed on the outer periphery of the first cylindrical body, the first cylindrical body being disposed in a first through hole, a third sealing member 61 being disposed between the inner wall of the first through hole and the first cylindrical body, and the first flange abutting against the inner wall of the end cap 20. In this embodiment, the second sealing assembly 60 includes a fourth sealing member 62, the fourth sealing member 62 being disposed between the inner wall of the end cap 20 and the first flange, for sealing the gap between the first flange and the inner wall of the end cap 20.

[0068] In an optional embodiment, an oil seal structure 70 is provided between the output shaft 411 of the water pump motor 41 and the mounting base 50 to seal the gap between the output shaft 411 and the mounting base 50, so as to prevent external liquid from entering the mounting cavity 11 from the gap between the output shaft 411 and the mounting base 50.
