The half-tooth setting of the fourth gear 470 drives the moving frame 450 to move.

[0028] Embodiment three:

[0029] like Figures 3 to 5 As shown, on the basis of retaining all the technical features in specific embodiment one and / or embodiment two (or the difference between this embodiment and specific embodiment one and / or embodiment two is that), in this embodiment: one side of the movable frame 450 is connected to the push rod 4620 through a connecting plate, the push rod 4620 is slidably installed inside the column 460, the column 460 is fixedly installed on one side of the water tank 4610, the side wall of the water tank 4610 is provided with an air vent, and a one-way valve is installed inside the air vent, one side of the column 460 extends to the inside of the water tank 4610 through a water suction pipe 4630, and the other side of the column 460 is connected to the spray head 4650 through a water outlet pipe 4640, and both the water outlet pipe 4640 and the water suction pipe 4630 are installed with a one-way valve.
