The working principle is as follows:
after the device is assembled and opened as shown in the figure, the driving rod 2 can drive the spiral blade 3 to rotate rapidly, the spiral blade 3 can pump water flow under the matching 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 matching of the communicating pipe 12 along with the flowing of the water, so that the first filter cover 7 and the second filter cover 9 rotate, and foreign matters attached to the surface of the first filter cover 7 due to the suction force of a pump can be thrown out due to the rotation of the first filter cover 7, thereby avoiding shielding filter holes which are avoided by the first filter cover 7; the second filter cover 9 is rotated to the same way to achieve the effect of avoiding smaller debris from being adsorbed on the surface of the second filter cover 9, meanwhile, the first filter cover 7 can be pushed 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 second filter cover 9 by the sliding plate 6, so that the polarization effect is achieved, 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 towards one side, the rubber top block 15 can block the filter holes on the surface of the first filter cover 7 in the moving direction, the 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 simultaneously, 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, at the moment, water flow can be blocked from the filter holes to enter between the first filter cover 7 and the second filter cover 9, therefore, the condition that foreign matters in the filter holes are driven by water flow to further move between the first filter cover 7 and the second filter cover 9 can be avoided, and the foreign matters clamped in the filter holes can be diagnosed to a great extent under the inertia of the foreign matters because the filter holes are positioned in the vibration radial direction;
while the second filter housing 9 can rotate and simultaneously drive the supporting block 18 to rotate through the transmission rod 17, and the support block 18 is rotated to continuously hit the conical filter cover 41 under the matching of the shifting blocks 19 at the two sides, so that the conical filter cover is moved upwards, and 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, and the movement of the limit plate 43 can press the return spring 45 to increase the elastic force recovery performance under the limit of the aggregate cover 20 to the limit plate 44, so that the conical filter housing 41 and the guide plate 42 can be integrally moved downward when the supporting block 18 continues to rotate to disengage the top toggle block 19 from the bottom toggle block 19 of the conical filter housing 41, therefore, the effect of continuous vibration is achieved, meanwhile, impurities or scrap iron attached to the surface of the conical filter cover 41 can flow into the aggregate cover 20 under the guide of the inclined surface, and finally, the discharge plate 21 is screwed out to discharge the impurities or scrap iron accumulated in the aggregate cover 20.
