The sealing bottom plate 15 rises and drives the triangular block 24 to press against the rotating cover 11 to make it in a vertical state. At this time, the rubber pad 2 13 blocks the liquid outlet pipe 9 so as to cooperate with the cleaning structure to perform brushing and cleaning operations. The structure of the drainage channel can be flexibly selected to facilitate the storage of the cleaning structure below.

[0033] Reference Figures 4 to 6The number of sliding blocks 16 is two groups, which are symmetrically arranged at both ends of the sealing chassis 15.

The cleaning curved rod 22 is pushed to the connection between the conical cylinder 2 and the underflow pipe 3, and the rotating motor 21 is started to drive the cleaning curved rod 22 to rotate for cleaning and brushing operations. Regular cleaning can prevent the liquid outlet from being blocked by accumulated dirt, and the cleaning structure is lifted and slidably connected to the underflow pipe 3, which is easy to store and use. The structure of the underflow pipe 3 and the conical cylinder 2 being separated is convenient for replacing the underflow pipe 3 structure that is easy to accumulate dirt and wear seriously. When the external threaded sleeve 7 and the internal threaded sleeve 6 are screwed together, the flange plate 4 at the bottom of the cylinder and the flange plate 5 at the top of the pipe are tightly connected to penetrate The conical cylinder 2 and the bottom flow pipe 3 are connected, and a sealing rubber ring structure is provided between the bottom flange 4 of the cylinder and the top flange 5 of the pipe to improve the sealing of the connection.
