[0027] Specifically, the filter component 4 provided can filter the water entering the connecting pipe 3, and can buffer large particles during filtration. After filtration, self-cleaning operation can be performed. The auxiliary component 5 provided can collect impurities during self-cleaning.

[0028] like Figure 2 - Figure 5 As shown, the filter assembly 4 includes a connecting shaft 401 arranged on the side of the water pump body 1, and the connecting shaft 401 passes through the water pump body 1 and is fixedly connected to the side position of the impeller 2. The connecting shaft 401 is a circular shaft. A push rod 402 is arranged inside the connecting shaft 401 and the push rod 402 passes through the impeller 2. A rechargeable battery block is arranged on the side of the push rod 402. The push rod 402 is an electric push rod with a circular block fixedly connected to the side. A filter plate 403 is fixedly installed inside the connecting pipe 3. The filter plate 403 is a circular plate with circular holes equidistantly opened on the side. A connecting block 404 is arranged at the center of the filter plate 403. The connecting block 404 is a convex block with a wear-resistant circular block fixedly installed on the side. A constraint groove 405 is provided on the inner side corresponding to the position of the filter plate 403. The constraint groove 405 is a circular groove with a cross-shaped cross section. A constraint plate 406 is movably installed inside the constraint groove 405 and the constraint plate 406 is fixedly installed at the side position of the connecting block 404. The constraint plate 406 is a circular plate with fan-shaped grooves equidistantly provided on the side. A support cylinder 407 is provided between the two sides of the constraint plate 406 and the inner wall of the constraint groove 405. The support cylinder 407 is a spring steel cylinder with a continuous "W"-shaped cross section. Cleaning strips 408 are fixedly installed at equal distances on the side of the constraint plate 406 close to the filter plate 403 and the cleaning strips 408 are attached to the side position of the filter plate 403. The cleaning strips 408 are circular strips made of rubber.

[0030] like Figure 2 、 Figure 3 and Figure 5 As shown, the auxiliary component 5 includes a collecting box 501 that is arranged on the side of the connecting pipe 3 at a position corresponding to the filter plate 403. The collecting box 501 is a rectangular box with a hollow side. A mounting cavity 502 is opened on the side of the collecting box 501. The mounting cavity 502 is a rectangular groove with a convex cross-section. A clamping groove 503 is opened on the inner side of the connecting pipe 3 at a position corresponding to the mounting cavity 502. The clamping groove 503 is a rectangular groove.

The linkage rod 506 pushes the card block 504 to slide to its internal position inside the installation cavity 502, and the collection box 501 can be disassembled. On the contrary, when the collection box 501 is installed, the card block 504 is squeezed to slide inside the installation cavity 502 to squeeze the support block 505 to deform. When it reaches the position of the card slot 503, the card block 504 is elastically supported by the support block 505 and is clamped in the internal position of the card slot 503. After the filter assembly 4 is filtered and cleaned, the impurities scraped off can fall and be collected in the internal position of the collection box 501.
