In the working process of the invention, the working principle is as follows:
and (3) conventional filtering operation:
when the pump body 9 is started, the pressure of the liquid inlet is reduced, so that external 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 to realize the supply of the irrigation water;
and (3) cleaning:
when the outer wall of the filter screen 603 of the filter sleeve 6 is accumulated with dirt to a certain degree, the holes of the filter screen 603 are blocked, so that the irrigation water in the filter sleeve 6 is gradually reduced, and because the pump body 9 always works, 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 can push the first end cover 7 to move towards the liquid inlet direction, 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 in contact with the brush body 302 of the dirt cleaning brush 3, so that the dirt accumulated on the outer wall of the filter screen 603 is brushed down by the brush body 302, so as to realize the dirt cleaning operation;
resetting the filter sleeve 6:
in the moving process of the first end cover 7, the second end cover 8, the filter sleeve 6 and the sliding sleeve 4, the push block 17 connected with the second end cover 8 through the sliding rod 16 is preferentially contacted with the stop block 503 of the limiting mechanism 5, so that the sliding rod 16 and the second end cover 8 stop moving, at this time, the first end cover 7, the filter sleeve 6 and the sliding sleeve 4 still continue to move towards the liquid inlet direction, a gap is generated between the first end cover 7 and the second end cover 8, irrigation water enters the pressure relief hole 704 of the first end cover 7 through the gap and finally enters the whole mechanism, so that the pressure inside the whole mechanism gradually rises, along with the gradual equalization of the internal pressure and the external pressure, the elastic force of the spring disk 10 can push the sliding sleeve 4 to slide towards the direction far away from the liquid inlet on the outer wall of the connecting seat 1, so that the filter sleeve 6 synchronously moves along with the sliding sleeve 4, and in the process, the filter sleeve 6 drives the first end cover 7 and the second end cover 8 to synchronously move, when the second connecting ring 802 of the second end cap 8 contacts with the end sleeve 13, the second end cap 8, the sliding rod 16 and the pushing block 17 stop moving, the first end cap 7, the filter sleeve 6 and the sliding sleeve 4 continue moving, and when the first end cap 7 is completely contacted with the second end cap 8, the filter sleeve 6 and the sliding sleeve 4 stop moving, so that the filter sleeve 6 is reset.
