[0037] As shown in Figures 1-5 The present application provides a self-priming pump inlet filter device, comprising: a filter assembly 1, a cleaning assembly 2 and a siphon 3.

[0038] The filter assembly 1 comprises a filter sleeve 10, the filter sleeve 10 is provided with filter cotton 11, and the filter sleeve 10 is arranged at the inlet end of the siphon 3; the filter sleeve 10 covers the water inlet end of the siphon 3, and the filter cotton 11 filters the impurities in the water, preventing the impurities from blocking the pipe opening of the self-priming pump after pumping water for a long time, thereby affecting the service life of the self-priming pump.

[0039] The cleaning assembly 2 comprises a driving member 20 and a brush 21 arranged on the side of the filter sleeve 10, and the driving member 20 is used to control the brush 21 to clean the impurities on the outer surface of the filter sleeve 10. When the filter sleeve 10 is used for filtering, the suction force generated by the self-priming pump will cause many garbage to be adsorbed on the surface of the filter sleeve 10, and the garbage will affect the pumping rate after being accumulated for a long time. The brush 21 is used to rotate and wipe the outer surface of the filter sleeve 10, so that the garbage is swept down and sinks.

[0040] In an embodiment, the filter sleeve 10 is made of UPVC pipe, and a plurality of filter holes 100 are formed on the outer surface of the UPVC pipe. The UPVC pipe is used to filter the garbage and impurities in the water tank, and the material is simple and convenient for production. It should be noted that the UPVC pipe is only a specific embodiment of the present application, and the filter sleeve 10 can also be made of other materials.

[0041] In an embodiment, the outer diameter of the UPVC pipe exceeds the pipe opening diameter of the siphon 3 by 4-8 cm, and the diameter of the filter hole 100 is 10-20 mm. The UPVC pipe needs to be selected according to the specifications of the siphon 3 to ensure that the UPVC pipe can be sleeved on the water inlet pipe opening of the siphon 3, and the diameter of the filter hole 100 is determined according to the size of the impurities in the water tank to ensure the maximum water inlet efficiency.
