[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Please refer to the following: Figures 1 to 7This utility model provides a battery with a waterproof shell, which includes a waterproof shell 1 and a battery module 2 housed inside the waterproof shell 1. The waterproof shell 1 specifically includes a first shell 11 and a second shell 12, which together form a receiving cavity 13. The battery module 2 is housed in this receiving cavity 13. A sealing ring 14 is provided between the first shell 11 and the second shell 12. The sealing ring 14 surrounds the outer periphery of the receiving cavity 13. The sealing ring 14 is injection molded into an integral structure with the first shell 11 through a secondary molding process in a mold. A conical rib 121 protrudes from the side of the second shell 12 facing the first shell 11 (which can be understood as the bottom surface of the second shell 12). In addition, the first shell 11 and the second shell 12 are connected by a snap-fit ​​connection. When the first shell 11 and the second shell 12 are connected to each other, the conical rib 121 will compress the sealing ring 14, so that the battery module 2 is sealed in the receiving cavity 13.

[0034] Specifically, this technical solution employs a two-stage injection molding process within a two-color mold to integrally mold the sealing ring 14 with the first housing 11. This reduces the need for manual placement of the sealing ring 14, thereby reducing production time, saving labor costs, and improving production efficiency. Furthermore, this solution reduces the risk of poor waterproofing due to improper placement of the sealing ring 14. In addition, this solution includes a conical rib 121 for compressing the sealing ring 14, which further enhances the waterproofing of the waterproof housing 1. The snap-fit ​​connection between the first housing 11 and the second housing 12 ensures that the conical rib 121 can compress the sealing ring 14, thereby ensuring that the waterproof housing 1 has excellent waterproofing performance, easily achieving an IPX5 waterproof rating.

[0035] Please refer to the following: Figure 2 and Figure 5 The outer wall of the waterproof housing 1 has a through hole 15, which connects to the accommodating cavity 13. The connector 21 on the battery module 2 protrudes outward through this through hole 15. The connector 21 allows the battery module 2 to supply power to external electrical appliances or to charge the battery module 2 from an external power source. To prevent external liquid from entering the accommodating cavity 13 through the through hole 15, this design requires a waterproof structure 16 between the connector 21 and the wall of the through hole 15 to seal the gap between them. The waterproof structure 16 can be a waterproof adhesive or a silicone sealant. In addition to waterproofing the battery module 2, the waterproof housing 1 of this design can also be used to waterproof other electrical components.

[0036] Please refer to the following: Figures 2 to 4The first housing 11 is provided with a sealing groove 111, which is actually arranged in a ring around the outer periphery of the accommodating cavity 13. The aforementioned sealing ring 14 is injection molded integrally with the first housing 11 within this sealing groove 111. By confining the sealing ring 14 within the sealing groove 111, on the one hand, the injection area between the sealing ring 14 and the first housing 11 can be increased to improve the interlocking force between the sealing ring 14 and the first housing 11, thereby improving the reliability of the sealing ring 14 being fixed in the first housing 11. On the other hand, the sealing ring 14 is confined within the sealing groove 111 and deforms. When the conical bone position 121 compresses the sealing ring 14, it helps to further improve the reliability of the sealing ring 14 sealing the accommodating cavity 13. In addition, the first housing 11 has a raised edge 112 protruding on the inner side of the sealing groove 111, and the second housing 12 has a recessed groove 122 on the inner side of the conical bone position 121. The raised edge 112 is inserted into this groove 122. By setting the groove 122 and the raised edge 112 inserted into the groove 122, it is beneficial to prevent liquid from entering the receiving cavity 13 after passing the sealing ring 14, thereby further improving the waterproof performance of the waterproof housing 1.

[0037] Please refer to the following: Figure 6 and Figure 7 The protruding edge 112 has multiple buckles 113 protruding on one side facing away from the sealing ring 14, and the groove wall of the groove 122 has a slot 123 at the position corresponding to each buckle 113. The multiple buckles 113 are snapped into the corresponding slot 123 one by one to realize the snap connection between the first housing 11 and the second housing 12. It can be seen that by setting the protruding edge 112 and the groove 122, in addition to further improving the sealing between the first housing 11 and the second housing 12, it is also beneficial to set the buckles 113 and the slots 123, making the structure of the waterproof shell 1 more compact and reasonable.

[0038] Please refer to the following: Figure 6 and Figure 7 The second housing 12 is divided into a first end region 124, a middle region 125, and a second end region 126 in the length direction. The sealing ring 14 is disposed on the middle region 125. The first housing 11 and the second housing 12 are snap-fit ​​connected in the middle region 125. The first housing 11 and the second housing 12 are fixedly connected in the first end region 124 and the second end region 126 by fasteners 17, preferably bolts. By fixing both ends of the second housing 12 to the first housing 11 by fasteners 17, it is beneficial to increase the pressure of the conical bone 121 on the sealing ring 14, and ensure that the conical bone 121 can reliably compress the sealing ring 14, thereby further improving the reliability of the sealing ring 14 in sealing the accommodating cavity 13.

[0039] Please refer to the following: Figures 1 to 7The waterproof housing 1 of this embodiment also includes a button 10, a limiting shell 18, and an elastic element 19. The button 10, the limiting shell 18, and the elastic element 19 are all disposed on the side of the second housing 12 facing away from the first housing 11. The button 10 is rotatably connected to the limiting shell 18. The limiting shell 18 is provided with a through first clearance hole 181 and a second clearance hole 182. The button 10 specifically includes a pressing part 101 and a protruding buckle part 102. The pressing part 101 protrudes from the first clearance hole 181 so that the user can press the pressing part 101. The protruding buckle part 102 protrudes from the second clearance hole 182. The battery is designed to engage with the main body of an external electrical appliance, allowing the entire battery to be inserted into the appliance. The elastic element 19 is positioned between the pressing part 101 and the second housing 12. When the pressing part 101 is subjected to the elastic force of the elastic element 19, the protruding part 102 tends to pop outward from the second clearance hole 182, thereby ensuring that the protruding part 102 can be reliably fastened into the interior of the external electrical appliance. When the battery needs to be removed, simply press the pressing part 101 downward to disengage the protruding part 102 from the appliance, and the entire battery can be easily removed.

[0040] Please refer to the following: Figure 6 and Figure 7 The first housing 11 has a first limiting hole 114 on its top, and the limiting shell 18 has a second limiting hole 183 on the side facing the first housing 11 (i.e., the bottom surface of the limiting shell 18). The first limiting hole 114 and the second limiting hole 183 together form a circular rotating hole. The button 10 has a rotating shaft 103 protruding from its side. This rotating shaft 103 is inserted into the rotating hole, thereby realizing the rotating connection between the button 10 and the limiting shell 18. When installing the button 10, the rotating shaft 103 of the button 10 needs to be placed in the first limiting hole 114 first, and then the limiting shell 18 is placed, so that the rotating shaft 103 of the button 10 is simultaneously restricted in the second limiting hole 183. Finally, the first housing 11 and the limiting shell 18 are locked together from bottom to top using fasteners 17. At this time, the limiting shell 18 and the first housing 11 will firmly clamp the second housing 12. Preferably, the first housing 11 and the limiting housing 18 will jointly clamp the first end region 124 of the second housing 12 in the vertical direction. As for the second end region 126 of the second housing 12, it can be directly fixed to the first housing 11 in the vertical direction by fasteners 17.

[0041] This embodiment also provides a cleaning device, which includes a cleaning body (not shown in the figure) and the aforementioned battery. The waterproof casing 1 is connected to the cleaning body. This can be understood as either a non-removable fixed connection between the waterproof casing 1 and the cleaning body, or a detachable connection between the waterproof casing 1 and the cleaning body to facilitate the removal of the entire battery. When the battery and cleaning body are assembled, the battery module 2 is actually electrically connected to the cleaning body to provide the electrical energy required for the cleaning body to operate. For example, the cleaning body may include a walking mechanism that moves on the ground and a mop. The cleaning body may also include a vacuum suction mechanism and a rotating roller brush for sweeping up debris.

[0042] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
