Working principle:
After the equipment is assembled and opened as shown in the figure, the driving rod 2 can drive the spiral blade 3 to rotate rapidly, the rotation of the spiral blade 3 can pump water flow under the cooperation of the pump body 1, the guide mechanism 4, the communicating pipe 5, the first filter cover 7 and the second filter cover 9, and the water can impact the inner walls of the first filter cover 7 and the second filter cover 9 under the cooperation of the communicating pipe 12 along with the flow of the water, so that the first filter cover 7 and the second filter cover 9 rotate, and foreign matters attached to the surfaces of the first filter cover 7 due to the suction of the pump can be thrown out due to the rotation of the first filter cover 7, so that the filter holes avoided by the first filter cover 7 are prevented from being shielded; the second filter cover 9 rotates to the same process, so that the effect of preventing smaller scraps from being adsorbed on the surface of the second filter cover 9 can be achieved, meanwhile, the rotation of the first filter cover 7 can push the first filter cover 7 to move laterally through the rubber top block 15 under the limit of the communicating pipe 5 to the first filter cover 7 and the sliding plate 6 to the second filter cover 9, so that the effect of polarization is achieved, and because the rubber top block 16 and the rubber top block 15 are in the same radial direction, when the rubber top block 15 pushes the first filter cover 7 to move to one side, firstly the rubber top block 15 can block the filter holes on the surface of the first filter cover 7 in the moving direction, foreign matters in the holes are prevented from entering between the first filter cover 7 and the second filter cover 9 due to inertia, and meanwhile, because the rubber top block 16 blocks the filter holes on the other side of the surface of the first filter cover 7 along the same radial direction, water flow can be prevented from entering between the first filter cover 7 and the second filter cover 9, so that the water flow can be prevented from driving the foreign matters in the filter holes to move to the first filter cover 7 and the second filter cover 9 in the radial direction at the moment, therefore, the foreign matters stuck in the filter holes can be diagnosed to a great extent under the inertia of the foreign matters;
The second filter cover 9 can rotate while driving the supporting block 18 to rotate through the transmission rod 17, the supporting block 18 can continuously strike the conical filter cover 41 under the cooperation of the poking blocks 19 at two sides, so that the conical filter cover 41 moves upwards, the limiting plate 43 can be driven by the guide plate 42 to move upwards due to the movement of the conical filter cover 41, the reset spring 45 can be extruded by the limiting plate 43 under the limitation of the aggregate cover 20 to the positioning plate 44, so that the elastic recovery performance of the reset spring 45 is improved, when the supporting block 18 continues to rotate, the poking block 19 at the top of the supporting block is separated from the poking block 19 at the bottom of the conical filter cover 41, the conical filter cover 41 and the guide plate 42 can integrally move downwards, thereby achieving the effect of continuous vibration, and simultaneously, impurities attached to the surface of the conical filter cover 41 or impurities can flow into the aggregate cover 20 under the guidance of the inclined plane of the conical filter cover 41, and finally the scrap iron 21 is screwed out, so that impurities or accumulated impurities or aggregates in the aggregate cover 20 can be discharged.
