At the same time, by using the triangular filter plate 8, while filtering the water, impurities and garbage in the water will fall to both sides, thereby not affecting the water flow in the inner cavity of the filter box 7.

[0034] Working principle: When in use, the triangular filter plate 8 can be used to guide the garbage in the inner cavity of the filter box 7 to both sides to prevent the garbage from clogging the triangular filter plate 8 and affecting the flow of water. When the staff needs to clean the inner wall of the water pipe 6, they push the push plate 202. The push plate 202 drives the positioning plate 201 to move when it moves. The positioning plate 201 drives the cleaning brush 203 to move when it moves. The cleaning brush 203 pushes the baffle 4 to move during the movement. The baffle 4 rotates around the axis of the shaft pin and It is adsorbed and connected to the magnetic block 10 at the upper end. When the cleaning brush 203 moves to the inner cavity of the water pipe 6, the staff pulls the push plate 202 horizontally left and right, so that the cleaning brush 203 in the inner cavity of the water pipe 6 can move back and forth left and right to clean the inner wall of the water pipe 6. After cleaning, the staff moves the push plate 202 to the far left, and then presses the push rod 11 downward. The push rod 11 applies pressure to the baffle 4 when moving downward, causing the baffle 4 to break away from the adsorption connection with the magnetic block 10, and the water diversion operation can continue.
