Water enters the inner cavity of the filter flask from the water inlet end, impurities are remained in the inner cavity of the filter flask after being filtered by the wavy filter screen, and the filtered water is discharged from the inner cavity of the framework and then to the water outlet end. When the impurities are accumulated to a certain degree, the valve is opened, the sewage impurities are discharged out of the sewage discharge port, and the filter bottle is cleaned up. Because the cross section of the wave-shaped filter screen is in the shape of a gear, the plane is larger than the contact area of water, so that more meshes are formed, the service time is longer, and the maintenance times are reduced.

Further, the skeleton bottom has the convex baffle that is circular shape, the skeleton upper end inlay card has the fender ring, keeps off the ring outside and has four convex stoppers, wave filter screen upper end supports and leans on keeping off the ring, and wave filter screen lower extreme supports and leans on the baffle.

Furthermore, the inner wall of the filter flask is provided with a limiting groove with an upward opening, and the limiting block is embedded into the limiting groove.

Furthermore, a plurality of protruding steps distributed in the circumferential direction are arranged at the bottom of the inner wall of the filter bottle, and the bottom of the framework is abutted against the steps.

Furthermore, the valve comprises a valve core, a valve ball, an adjusting plate and a valve body, wherein a connecting pipe is clamped in the sewage discharge port and is connected with the valve core through threads, the valve ball is connected in the valve core in a rotating mode, the valve body is sleeved outside the valve core, a rotating shaft is arranged at one end of the adjusting plate and penetrates through the valve body and the valve core to be fixedly connected with the valve ball, and an adjusting through hole is formed in the valve ball.

Compared with the prior art, this take leading filter of high-efficient filtration formula of wave filter screen has following advantage:

1. the cross section of the wave-shaped filter screen is in a gear shape, so that the plane is larger compared with the contact area of water, the meshes are more, the service time is longer, and the maintenance times are reduced.

2. The valve is provided with an adjusting plate, the valve is convenient to open or close, and the adjusting plate can be rotated.
