When the seal 43 is inserted into the filter cavity 32, the seal 43 is aligned with the water inlet pipe 7, so that the water in the water inlet pipe 7 can achieve sealing cooperation with the seal 43, so that the water in the water inlet pipe 7 can directly enter the inner cavity 40.

[0034] When in use: the water pump body 1 and the motor 2 are started, so that the water in the swimming pool flows into the inner cavity 40 through the water inlet pipe 7, and the output shaft 21 rotates to drive the winding strip 22 to rotate, so that the hair in the water is wound around the winding strip 22, and the cleaned water flows out through the filter screen 42 to achieve the first filtration, and then the water in the filter cavity 32 flows through the connecting hole 31 to the clean water cavity 33 located below the filter element 5. When the water flow is large, the movable plate 53 moves upward to disengage the matching block 532 from the matching groove, so that the matching groove is opened, so that the water flow can pass The water flows through the water hole 503 and the installation hole 502 to the water purification chamber 33 located above the filter element 5, and also needs to pass through the filter cotton 52. Therefore, the sand and impurities are filtered through the filter cotton 52, thereby achieving further water purification, making the water cleaner, and the sand and impurities on the filter cotton 52 will fall off and fall into the slope 332 at the bottom of the water purification chamber 33, and roll onto the sealing cover 6 through the slope 332. When it is necessary to clean the water purification chamber 33, it is only necessary to open the sealing cover 6 to clean the water purification chamber 33, thereby achieving the function of cleaning the water purification chamber 33.

[0035] In addition, when the filter 42 or the winding strip 22 needs to be cleaned, it is only necessary to remove the bolts on the cover body 41, manually pull the handle 411, and remove the filter 42 and the cover body 41 from the filter chamber 32. At this time, the winding strip 22 can be directly cleaned manually, and the filter 42 can be cleaned, so the cleaning effect is better, making the equipment service life longer.
