As shown in fig. 12, when the water diversion member 300 is driven to rotate by the toggle handle 600 so that the water through hole 213 is located above the water purification channel 320, the hollow shaft 210 is communicated with the water purification channel 320, and water flows into the water purification channel 320 through the water through hole 213 and the channel opening 292 after passing through the hollow shaft 210, and then overflows from the flow gap to the water purification pipe 281 to be discharged.

Therefore, the water channel of the embodiment is axially arranged, and the hollow shaft 210 can be communicated with the raw water channel 310 or the purified water channel 320 by driving the water diversion member 300 to rotate around the axis of the water inlet, without arranging other through holes on the peripheral side of the hollow shaft for switching the water channel, so that the structure of the hollow shaft can be simplified, and the processing cost of the hollow shaft can be reduced; in addition, because the two ends of the hollow shaft in the embodiment are the water inlet end and the water outlet end, only water sealing points are needed to be arranged at the two ends of the hollow shaft, so that the number of the water sealing points and the use number of sealing pieces are reduced, the assembly efficiency of the control valve is improved, and the manufacturing cost is reduced; finally, the valve element 200 and the water diversion member 300 of the present invention are installed in an axial stacking manner, so that the assembly is simple and convenient.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
