Description

Technical Field

[0001] This utility model belongs to the field of swimming pool pump technology, and specifically refers to a swimming pool pump with a double sealing structure. Background Technology

[0002] Pool pumps are water pumps used in swimming pools and similar settings. They can be applied in residential areas, schools, swimming pools, fitness centers, bathhouses, and other places requiring a large flow of hot water. They draw pool water into the pump, filter and purify it, and then return the treated water to the pool, creating a water circulation system. This effectively keeps the pool water clear and clean, preventing water accumulation at the bottom and a decrease in alkalinity. It also removes impurities, solid particles, organic matter, and bacteria from the pool water, ensuring its quality and cleanliness. To prevent short circuits at the wiring connections inside the capacitor box, some pool pumps on the market add a waterproof structure to seal the capacitor box, but the sealing effect is not always good. Some manufacturers use glue injection to improve sealing performance, which provides a better seal, but internal problems lead to complicated and costly repairs. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] like Figures 1-6 As shown: A swimming pool water pump with a double-sealed structure includes a motor 1 and a pump body 2 connected to each other. A waterproof box 11 is provided at the upper end of the motor 1. The waterproof box 11 includes a box body 111 and a box cover 112. A sealing ring 113 is provided between the box body 111 and the box cover 112. A capacitor 12 and a terminal waterproof box 13 are provided inside the box body 111. A wire harness waterproof sleeve 114 is provided on one side of the box body 111. The terminal waterproof box 13 has a receiving space inside. The terminal waterproof box 13 includes a waterproof box body 131 and a waterproof cover 132. A sealing ring 113 is provided between the waterproof box body 131 and the waterproof cover 132. The waterproof box 131 is equipped with a second sealing ring, and the two ends of the waterproof box 131 are respectively provided with wire harness waterproof sleeves 134. This utility model is a double waterproof structure. The first layer of waterproofing is the waterproof box, and the second layer of waterproofing is the terminal waterproof box. The connection between the wire harness and the box is waterproofed by the first and second wire harness waterproof sleeves, preventing water from entering from the gaps at the connection between the wire harness and the waterproof box. In addition, both the waterproof box and the terminal waterproof box are equipped with sealing rings, which can improve the sealing performance. Even if there is a problem inside, it can be repaired by opening the waterproof box and the terminal waterproof box. The method is simple and the sealing performance is good. Specifically, the motor is a water-cooled motor.

[0027] In the aforementioned swimming pool pump with a double-sealed structure, the second waterproof cable clamp 134 includes a waterproof cable sleeve 1341, a locking sleeve 1342, a fixing nut 1343, and a locking nut 1344. The locking sleeve 1342 passes through the waterproof housing 131, and the waterproof cable sleeve 1341 is located inside the locking sleeve 1342. The locking nut 1344 and the adjusting nut 1343 are respectively screwed onto both ends of the locking sleeve 1342. The locking nut 1344 is used to clamp the wire inside the waterproof cable sleeve 1341, and the fixing nut 1343 is used to fix the position of the locking sleeve 1342 on the waterproof housing 131. The sleeve 1341 is provided with at least one wire hole 1345. Specifically, the present invention has three wire holes 1345, corresponding to the ground wire, neutral wire, and live wire, respectively. The waterproof sleeve 1341 is made of rubber. The end of the locking sleeve 1342 is provided with a deformation part 1346. The locking nut 1344 is provided with a deformation cap 1347 for controlling the inward deformation of the deformation part 1346. Specifically, this can facilitate the waterproof sleeve to clamp the wire, and the designed deformation part mainly serves to clamp the waterproof sleeve. The structure of the first waterproof sleeve for wire harness is basically the same as that of the second waterproof sleeve for wire harness, so it will not be described in detail here.

[0028] In the aforementioned swimming pool pump with a double sealing structure, the working surface of the deformation cap 1347 is an arc-shaped structure, and the deformation part 1346 is composed of multiple deformation plates. Specifically, this is to increase the extrusion pressure and further improve the sealing performance of the waterproof sleeve and the wire.

[0029] In the aforementioned swimming pool pump with a double sealing structure, the cross-section of the sealing ring 113 is a convex shape. Specifically, a rib is provided on the top of the box body, which contacts the lower side of the sealing ring 1. When the box cover is placed on the box body, the sealing performance can be improved by compression.

[0030] In the aforementioned swimming pool pump with a double sealing structure, multiple connecting posts 115 are respectively provided on the housing 111 and the cover 112. Specifically, this is to improve the connection and sealing performance between the housing and the cover, and the connecting posts are designed to be connected by bolts.

[0031] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
