Since the driving shaft 300 penetrates the rotary valve 200 and the diverter disc 400, a through hole is formed in the middle of the rotary valve 200 and the diverter disc 400, and the first sealing ring 610 is arranged to prevent water from penetrating through the through hole. The second sealing ring 620 is embedded on the side of the diverter disc 400 facing away from the rotary valve 200, and the shape of the second sealing ring 620 is matched with the shape and size of the diverter disc 400.

Referring to fig. 5, the adjusting slider 150 has a guide groove 151 formed on an outer circumferential surface thereof. A swirl chamber 152 is provided between the adjustment slider 150 and the housing 100, and the swirl chamber 152 is used for rotating the water flow passing through the swirl chamber.

The eccentric protrusion 320 is inserted into the guide groove 151 and is used to drive the adjusting slider 150 to move in the first water spraying channel 110 to adjust the flow rate of the water flowing through the swirl chamber 152, so that the water spray outlet can spray different water types. When the flow rate of the water flowing through the swirl chamber 152 reaches a maximum value, that is, when the water in the first water spray passage 110 completely flows through the swirl chamber 152, the rotation speed of the water also reaches a maximum value, and at this time, the water sprayed from the first water spray passage 110 is dispersed by the centrifugal force and the coverage area is maximized. When the water flow in the first water spray passage 110 is directly sprayed without priority through the swirl chamber 152, the water flow is not substantially rotated, and thus the water spray is substantially cylindrical and the coverage area is minimized. In short, the nozzle 10 of the present application skillfully controls the flow rate of the water flowing through the swirl chamber 152 by arranging the adjusting slider 150 in the first water spraying channel 110, thereby realizing the full-range control of gradually changing the water type ejected from the first water spraying channel 110 from the maximum value to the minimum value of the coverage area, i.e. a single water spraying channel can eject multiple water types.
