[0020] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0021] Please see Figure 1-2 This utility model provides a waterproof sleeve for a miniature water pump, including a water pump body 1, a power line 2, and a waterproof protection device 3. The power line 2 is connected to the bottom of the water pump body 1, and the waterproof protection device 3 is installed on the outside of the water pump body 1.

[0022] Please see Figure 3-5 This utility model provides a waterproof sleeve for a miniature water pump. The waterproof protection device 3 includes a waterproof sleeve 31, a threaded sleeve 32, an upper threaded seat 33, a threaded cap 34, and a lower threaded seat 35. The waterproof sleeve 31 is fitted over the water pump body 1. The threaded sleeve 32 is rotatably and sealed at the top of the waterproof sleeve 31. The upper threaded seat 33 is nested and fixed on the surface of the water pump body 1. The upper threaded seat 33 is threadedly connected to the inner side of the threaded sleeve 32. The threaded cap 34 is rotatably and sealed at the bottom of the waterproof sleeve 31. The threaded cap 34 is connected to the inside of the waterproof sleeve 31. The power line 2 passes through the inner side of the threaded cap 34 and extends outward. The lower threaded seat 35 is nested and fixed on the surface of the power line 2. The lower threaded seat 35 passes through the waterproof sleeve 31 and is threadedly connected to the inner side of the threaded cap 34, thereby spirally sealing the upper and lower ends of the waterproof sleeve 31 and ensuring the sealing performance of the inside of the waterproof sleeve 31.

[0023] The surface of the power line 2 is wrapped with nylon braided mesh to enhance the torsional strength of the power line 2 and ensure that the lower threaded seat 35 and the threaded cap 34 can be properly screwed together and assembled.

[0024] Among them, the number of swivel turns between the upper threaded seat 33 and the threaded sleeve 32 is not less than 3, and the number of swivel turns between the lower threaded seat 35 and the threaded cap 34 is not less than 3, to ensure the sealing strength at both ends of the waterproof sleeve 31.

[0025] To further explain, the waterproof housing 31 is symmetrically provided with mounting ears 36 on the left and right sides, which facilitates screw installation of the waterproof housing 31 through the mounting ears 36.

[0026] To further explain, the waterproof casing 31 is symmetrically provided with fin groups 37 on the front and back. The fin groups 37 can enhance the heat dissipation performance of the waterproof casing 31 and meet the temperature control requirements of the water pump body 1.

[0027] The waterproof casing 31 in this utility model is made entirely of stainless steel. Stainless steel has excellent strength and corrosion resistance, as well as good thermal conductivity, which enables the waterproof casing 31 to better meet the external protection and heat dissipation requirements of the water pump body 1.

[0028] Specifically, during assembly, first, the power line 2 is passed through the inside of the threaded cap 34 and connected outwards. Then, the water pump body 1 is installed inside the waterproof housing 31 until the upper threaded seat 33 contacts the threaded sleeve 32. At this time, the threaded sleeve 32 is rotated to screw into the upper threaded seat 33, so that the top port of the waterproof housing 31 is spirally sealed. Then, the power line 2 is pulled to control the lower threaded seat 35 to contact the threaded cap 34. Finally, the threaded cap 34 is rotated to screw into the lower threaded seat 35, so that the bottom port of the waterproof housing 31 is spirally sealed. Thus, the water pump body 1 is sealed and installed inside the waterproof housing 31. Both ends of the waterproof housing 31 are spirally sealed. The disassembly and assembly operations are simple and do not require external tools, which greatly reduces the maintenance difficulty of the water pump body 1.
