The working principle of the utility model is as follows: during drainage, the impeller 8 is driven to drive the rotating plate 9 to rotate when water flows;
the first sliding head 12 and the second sliding head 13 generate centrifugal force while rotating, and as the mass of the first sliding head 12 is larger than that of the second sliding head 13, the centrifugal force of the first sliding head 12 overcomes the centrifugal force of the second sliding head 13 and the adsorption force of the permanent magnet 29 on the first sliding head 12, moves along the first groove 10 towards the edge of the rotating plate 9, and prys the second sliding head 13 towards the center of the rotating plate 9 by taking the second adjusting column 15 as the center of the circle; with the first sliding head 12 as a central line, the dirt blocking piece positioned at the front side of the first sliding head 12 is in a cleaning state, and the dirt blocking piece positioned at the rear side of the first sliding head 12 is in a filtering state in a clockwise direction;
with the time of filtering, the dirt blocking piece is blocked by the filtered garbage, so that the rotation resistance of water to the dirt blocking piece is increased, the rotation speed of the rotating plate 9 is reduced, the centrifugal force of the first sliding head 12 and the second sliding head 13 is reduced, when the centrifugal force is reduced to a certain extent, the centrifugal force of the first sliding head 12 is insufficient to overcome the centrifugal force of the second sliding head 13 and the adsorption force of the permanent magnet 29 to the first sliding head 12, the first sliding head 12 moves towards the circle center of the rotating plate 9 under the magnetic force of the permanent magnet 29, and the second sliding head 13 is pried to move towards the edge of the rotating plate 9 by taking the second adjusting column 15 as the circle center; at this time, the first sliding head 12 is a center line, the dirt blocking member located at the front side of the first sliding head 12 is in a filtering state, and the dirt blocking member located at the rear side of the first sliding head 12 is in a cleaning state in a clockwise direction;
when the dirt blocking parts on two sides of the first sliding head 12 are balanced, the dirt blocking parts are critical points, when the first sliding head 12 moves towards the circle center, the dirt blocking parts are cleaned under the scouring of water before the critical points are not reached, the resistance is reduced, the centrifugal force is gradually recovered, the first sliding head 12 is extracted to the edge under the action of the centrifugal force, when the dirt is not cleaned in time, the critical points are crossed, and at the moment, the original dirt blocking part filtering state is changed into a cleaning state;
when the rotating plate 9 rotates, the scraping plate 28 is driven to rotate, so that the scraping plate 28 cleans the filter cage 6 to ensure normal water discharge, and water discharge cannot be influenced after a dirt blocking piece in a filtering state is blocked;
when the first sliding head 12 and the second sliding head 13 drive the first adjusting column 14 to move, the adjusting head 18 drives the gear 21 to rotate relative to the first adjusting column 14, so that the gear 21 drives the dirt blocking member to rotate under the action of teeth, and the angle of the dirt blocking member is adjusted;
