Be fixed with slider 95 through sheet metal 94 outer wall symmetry, the setting that has the spout 97 that supplies slider 95 activity on the slider 95 rotation is connected with ball and the inner wall of spacing pipe 911 sunken is favorable to reducing the frictional force of sheet metal 94 and spacing pipe 911 inner wall for the floater 92 drives sheet metal 94 and goes up and down and remove along with the water level more easily.

The sealing ring 96 covering the water diversion hole 99 is fixed on one side, close to the water diversion hole 99, of the thin plate 94, so that the sealing performance between the thin plate 94 and the water diversion hole 99 is improved, water is not prone to flowing out through a gap between the thin plate 94 and the water diversion hole 99, the water level in the water storage tank 81 is not prone to exceeding a set value, meanwhile, the water in the water storage tank 81 is not prone to overflowing, waste of water resources is reduced, and resource saving is facilitated.

When the filter assembly 7 is cleaned, the movable plate 51 is pulled up in a direction away from the water storage tank 81, and then the net frame 71 is pulled out, so that dust which is blocked and accumulated on the dust filter cloth 73 is not easily blocked by the movable plate 51 when being pulled out, and further the dust is not easily dropped into the water storage tank 81; dismantle joint cap 74 on the rack 71 next, make joint cap 74 and fixed column separation, dismantle dust filter cloth 73 from rack 71, the dust that accumulates on the clearance dust filter cloth 73 again, later wash dust filter cloth 73 with the water, can install again on rack 71 after the sanitization, be favorable to improving the clean degree of dust filter cloth 73, make filter assembly 7 more easily with the dust separation, and then make the dust content of the water that flows into water storage box 81 lower, and simultaneously, make dust filter cloth 73 cyclic utilization, be favorable to resources are saved.

Through the detachable setting of dust filter cloth 73 and rack 71 for dust filter cloth 73 is dismantled and is installed more easily, makes the operation of dismantling and installing dust filter cloth 73 more convenient, makes the dust of separation on dust filter cloth 73 more easily cleared up, makes the operation of clearing up the dust more convenient.

The inner walls of the four round holes of the dust filter cloth 73 are fixed with the circular rings, so that the round holes are protected by the circular rings, the dust filter cloth 73 is not easy to damage, and meanwhile, the connection stability of the dust filter cloth 73 and the net rack 71 is improved, and the dust filter cloth 73 is not easy to fall off from the net rack 71.

The dust filter cloth 73 is detached from the net frame 71 by detaching the snap cap 74, so that the operation is simpler and more convenient, and the cleaning of the dust filter cloth 73 is more convenient.

The cross-sectional area of the net frame 71 is larger than that of the water outlet 42, and the dust filter cloth 73 covers the surface of the net frame 71, so that water with dust flowing out of the water outlet 42 is easily concentrated and blocked on the dust filter cloth 73, the dust is not easily introduced into the water storage tank 81, and the content of the dust in the water storage tank 81 is reduced.

The handle 72 is fixed on the net frame 71, so that the net frame 71 can be taken out from the water storage tank 81 more easily, the dust filter cloth 73 connected to the net frame 71 can be cleaned more easily, and the operation of cleaning the dust filter cloth 73 is simpler and more convenient.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
