[0022] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.

[0023] As shown in the accompanying drawings. Figures 1-4

[0024] A water supply and drainage filtering device, comprising a filter box 1 as a main body, a detachable cover plate 3 is arranged above the filter box 1, as shown in the accompanying drawings. Figure 2 , the accompanying drawings. Figure 3 An inclined filter plate 4 is arranged in the inside of the filter box 1, an inlet pipe 11 is arranged at one end of the filter box 1 where the filter plate 4 is the highest, an extended cylinder 2 is installed in the filter box 1 at one end where the filter plate 4 is the lowest through bolts, an intermediate partition 21 with the same inclination angle as the filter plate 4 is arranged in the inside of the extended cylinder 2, and the upper surface of the intermediate partition 21 is in the same plane as the filter plate 4.

[0025] Based on the above structure, after the water flow enters the inside of the filter box 1 from the inlet pipe 11, the water flow can be filtered under the action of the mesh holes of the filter plate 4 itself, and the impurities will be blocked above the filter plate 4, and under the action of the inclination angle of the filter plate 4 itself and the water flow impact, these blocked impurities will enter the extended cylinder 2 and accumulate above the intermediate partition 21.

[0026] On the basis of the above structure, a plurality of secondary filter holes 22 are arranged in the intermediate partition 21, which can perform secondary water draining on the impurities accumulated above, and the drained water flow can flow back into the filter box 1 through the bottom plate of the extended cylinder 2, as shown in the accompanying drawings.
