In the working process of the invention, the working principle is as follows:
conventional filtration operation:
when the pump body 9 is started, the pressure of the liquid inlet is reduced, so that the outside irrigation water enters the filter sleeve 6 through the filter screen 603 of the filter sleeve 6 under the action of water pressure and then enters the liquid inlet of the pump body 9 through the connecting seat 1, and is pumped out under the action of the pump body 9, so that the irrigation water is supplied;
and (3) cleaning:
when the outer wall of the filter screen 603 of the filter sleeve 6 is polluted to a certain extent, the holes of the filter screen 603 are blocked, so that irrigation water in the filter sleeve 6 is gradually reduced, and the pump body 9 is always in operation, so that the pressure in the filter sleeve 6 is gradually reduced, at the moment, under the action of external water pressure, the second end cover 8 pushes the first end cover 7 to move towards the liquid inlet, so that the filter sleeve 6 is driven to push the sliding sleeve 4 to compress the disc spring 10, and in the movement process of the filter sleeve 6, the filter screen 603 of the filter sleeve 6 is contacted with the brush body 302 of the sewage cleaning brush 3, so that the polluted water on the outer wall of the filter screen 603 is brushed down by the brush body 302, and the sewage cleaning operation is realized;
resetting the filter sleeve 6:
