An elastic band 12 is fixedly connected to the outer surface of the top of the bottom plate 1. The other end of the elastic band 12 is fixedly connected to a plug 13. A positioning seat 11 is fixedly connected to the outer surface of the top of the bottom plate 1. A limiting groove 14 is formed on the outer surface of the plug 13. A movable rod 16 is movably inserted into one side of the positioning seat 11 close to the limiting groove 14. A limiting block 15 is fixedly connected to one side of the movable rod 16 close to the limiting groove 14.

The water hose 10 is limited by the elastic band 12 to prevent the water hose 10 from becoming loose. When the water hose 10 needs to be used, pull the movable rod 16 to make the limiting block 15 disengage from the limiting groove 14. The third spring 18 resets to drive the plug 13, and the plug 13 can be ejected.
[0025] In this embodiment, two sliding rods are movably inserted into the outer surface of the connecting plate. The other ends of the two sliding rods are fixedly connected to the cleaning brush 8. Two first springs 7 are respectively sleeved on the outer surfaces of the two sliding rods. Specifically, the first springs 7 are limited by the sliding rods to prevent the first springs 7 from deforming obliquely.

The collection drawer is fixed to the outer surface of the rear side of the filter box 3 by bolts. Specifically, when it is necessary to take out the collection drawer to collect the impurities inside it, unscrew the bolts and remove the collection drawer.
[0027] In this embodiment, a mounting plate is fixedly connected to the outer surface of the top of the fixing plate 4. The mounting plate is fixed to the outer surface of the top of the filter box 3 by bolts. Specifically, when it is necessary to disassemble the sieve plate 5, unscrew the bolts and drive the fixing plate 4 to be pulled out by pulling out the mounting plate.
[0028] In this embodiment, two positioning rods 9 are fixedly connected to the outer surface of the top of the bottom plate 1. The water hose 10 is wound around the outside of the two positioning rods 9. Specifically, the water hose 10 bypasses the positioning rods 9 so that the water hose 10 is wound into a circular ring shape, and the inner side of the water hose 10 is positioned by the positioning rods 9.
[0029] In this embodiment, a third spring 18 is fixedly connected to the inner surface of the bottom of the positioning seat 11.

[0031] Working principle: When the present utility model is in use, the water pump body 2 operates. During the process of the water pump body 2 pumping water, water flows into the filter box 3, and impurities in the water flow are filtered by the sieve plate 5. The impurities remain on the surface of the sieve plate 5. During the pumping process, under the impact of the water flow, the impeller blades rotate. When the impeller blades rotate, they drive the rotating shaft 6 to rotate. The rotating shaft 6 rotates to drive the cleaning brush 8 to clean the surface of the sieve plate 5. When the cleaning brush 8 rotates, it cleans the impurities remaining on the surface of the sieve plate 5, so that the impurities on the surface of the sieve plate 5 can be brushed off while the water pump body 2 is operating, avoiding the blockage of the sieve plate 5, thus facilitating the cleaning of the surface of the sieve plate 5. The impurities fall into the collection drawer for collection.
[0032] When the water pump body 2 is not needed, the water hose 10 is stored. At this time, the water hose 10 is wound around the outside of the positioning rod 9. After winding is completed, the elastic band 12 is pulled, so that the insertion block 13 at one end of the elastic band 12 is inserted into the inside of the positioning seat 11. The movable rod 16 is pulled, causing the second spring 17 to deform. The movable rod 16 drives the limit block 15 to move. When the positions of the limit groove 14 and the limit block 15 correspond to each other, the force applied to the movable rod 16 is stopped. Under the elastic force of the second spring 17, the limit block 15 is driven to be inserted into the inside of the limit groove 14, and the water hose 10 is limited by the elastic band 12 to prevent the water hose 10 from becoming loose. When the water hose 10 is needed, the movable rod 16 is pulled, so that the limit block 15 is disengaged from the limit groove 14, and the third spring 18 resets to drive the insertion block 13, and the insertion block 13 can be ejected.
