[0039] The flushing assembly comprises a water inlet module and a driving module; the water inlet module provides a flushing water flow, and the driving module drives the stacked laminas 3 to press against each other, so that the pressure between the laminas 3 is increased; when the flushing water flow in the water inlet module flushes the laminas 3 through the water flow channel 7, the suddenly increased pressure between the laminas 3 drives the water flow to flush, thereby flushing stubborn dirt on the laminas 3 and ensuring the cleaning efficiency of the laminas 3.

[0040] As shown in Figure 4 the laminas 3 are stacked, the filter grooves 8 on the adjacent laminas 3 contact each other to form filter holes for filtering the particulate impurities in the water; the middle part of the filter groove 8 is penetrated by an arc-shaped groove 10, the arc-shaped groove 10 is communicated with the filter grooves 8, the flushing water flow passing through the water flow channel 7 enters the arc-shaped groove 10 and flushes and cleans the particulate impurities between the adjacent two laminas 3 in the direction of the filter groove 8; the arc-shaped elastic sheet 9 is installed in the arc-shaped groove 10, the arc-shaped elastic sheets 9 between the adjacent two laminas 3 contact each other to form a flow channel and provide power for the resetting of the laminas 3; the arc-shaped elastic sheet 9 is provided with a slot opening communicated with the filter groove 8.

[0041] As shown in Figure 2 the present application, a water blocking plate 11 is installed on one side in the filter housing 1, the water blocking plate 11 and the filter housing 1 form a sealed cavity, and the fixing frame 4 is rotatably and sealingly arranged with the water blocking plate 11; the laminas 3 to be cleaned are cleaned by the flushing assembly in the sealed cavity formed by the water blocking plate 11 and the filter housing 1.

[0042] In the present application, a recess corresponding to the stacked laminas 3 is formed on the upper side support plate 5, and a driving block 12 sliding up and down in the recess is installed; the lower surface of the shell cover 2 is fixed with a limiting ring 13, and the two ends of the limiting ring 13 are in contact with the outer wall of the water blocking plate 11, so that the laminas 3 in the sealed cavity formed by the water blocking plate 11 and the filter housing 1 are not pressed by the limiting block; the laminas 3 and the laminas 3 are supported by the arc-shaped elastic sheet 9 to form a certain gap, which can increase the water storage capacity of the flow channel and provide conditions for the high-pressure flushing water flow generated by the mutual pressing of the laminas 3; when the laminas 3 are pressed, a higher efficiency flushing water flow is provided to clean the particulate impurities in the filter groove 8; and the driving block 12 below the limiting ring 13 presses the laminas 3, so that the laminas 3 always maintain a state of adhesion, thereby ensuring the filtering effect of the filter.

[0043] In the application, the water inlet module comprises two water inlet sub-pipes 14 and a water inlet main pipe 15 in communication with the two water inlet sub-pipes 14; the water outlet pipe of the water inlet sub-pipe 14 is located in the sealing cavity, the distance between the water outlet ends of the two water inlet sub-pipes 14 is equal to the distance between the water flow grooves 7 on both sides of the laminated sheet 3, and is located on the rotating track of the fixed frame 4, so that the two water inlet sub-pipes 14 are aligned with the water flow grooves 7, and the water inlet main pipe 15 is in communication with the external water source.

When the laminated sheet 3 needs to be reset, the laminated sheet 3 can be reset at equal distances, thereby avoiding the situation that the bottom laminated sheet 3 is difficult to reset due to the gravity of the stacked laminated sheet 3. After the extruded and adhered laminated sheet 3 enters the sealing cavity and is driven to extrude by the elastic force of the arc-shaped elastic sheet 9, the laminated sheet 3 can be temporarily reset, thereby providing conditions for the driving module to drive the laminated sheet 3 to extrude and increase the water pressure.

[0051] In example two, the experimental method is basically the same as that of example one, except that test water is injected into filter I and filter II for 2h, then filter I and filter II are cleaned, the water consumption of filter I and filter II for cleaning the gasket is recorded within 1min, and the cleaning degree of the gasket in filter I and filter II is observed, and the experimental data is recorded.
