Anti-blocking drainage mechanism

The utility model relates to the technical field of drainage mechanisms, in particular to an anti-blocking drainage mechanism which comprises a shell, a conical leakage groove is formed in the upper surface of the shell, an installation base is fixedly installed on the lower surface of the shell, a support is arranged on the inner surface of the shell, and a filter screen is rotationally connected to the inner surface of the support. According to the drainage mechanism, the structures such as the support, the filter screen, the groove and the protruding block are arranged, in order to prevent the drainage pipe from being blocked, a special anti-blocking structure is designed for the drainage mechanism, the conical leakage groove of the drainage mechanism can be detached from the surface of the shell, and the filter screen is installed in the shell through the support; the filter screen can filter water from the conical leakage groove, the filtered water can flow out along the drainage hole below the support,
