The anti-vortex component is connected to the side net 2. The bottom net 1 and the upper pressure piece 3 are both connected to the side net 2. That is, the filtering structure is an integral structure, which can meet the needs of increasing the filtering area and preventing the generation of vortices in the drainage area. It integrates filtering and anti-vortex components into one, which is convenient for disassembly, cleaning and maintenance operations.

[0041] There is no limitation on the specific form of the anti-eddy current component, such as a plate type, a wheel type, etc., and reference may be made to the prior art.
