The arrangement of the tray 4 can support the rotating plate 9, and the friction force of the rotating plate 9 can be reduced by the balls.
This practical theory of operation: when water is drained, water flow drives the impeller 8 to drive the rotating plate 9 to rotate when flowing;
the first sliding head 12 and the second sliding head 13 can generate centrifugal force while rotating, and because the mass of the first sliding head 12 is greater 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 to the first sliding head 12, moves to the edge of the rotating plate 9 along the first groove 10, and pries the second sliding head 13 to move to the center of the rotating plate 9 by taking the second adjusting column 15 as the center of circle; taking the first sliding head 12 as a central line, along the clockwise direction, the dirt blocking part positioned at the front side of the first sliding head 12 is in a cleaning state, and the dirt blocking part positioned at the rear side of the first sliding head 12 is in a filtering state;
along with the filtering time, the dirt blocking member is blocked by the filtered garbage, so that the rotating resistance of water to the dirt blocking member is increased, the rotating 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 degree, the centrifugal force of the first sliding head 12 cannot 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 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 center of the circle; at this time, the first sliding head 12 is a central line, and along the clockwise direction, 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;
when the dirt blocking parts on the two sides of the first sliding head 12 are balanced, the critical point is formed, when the first sliding head 12 moves towards the center of the circle, the dirt blocking parts are cleaned under the washing of water before the critical point is reached, the resistance is reduced, the centrifugal force is gradually recovered, the first sliding head 12 is picked up and moved towards the edge under the action of the centrifugal force, when the dirt is not cleaned in time and crosses the critical point, and at the moment, the filtering state of the original dirt blocking parts is changed into a cleaning state;
when the rotating plate 9 rotates, the scraper 28 is driven to rotate, so that the scraper 28 cleans the filter cage 6 to ensure normal discharge of water, and the water discharge cannot be influenced after the dirt blocking piece in a filtering state is blocked;
