The rotating shaft 3 contacts with the cover 203 of the valve core 2 through a plurality of convex ribs 3015, so that the friction force between the rotating shaft 3 and the cover 203 in the rotating process can be reduced. The rib 3015 may be rounded to make the contact with the cover 203 of the valve element 2 be a line contact, which may further reduce the friction between the rotating shaft 3 and the cover 203 during the rotation process.

As shown in fig. 5a and 5b, a first notch slot 3011 is disposed at one end of the annular sleeve 301 close to the water inlet 601, and the first notch slot 3011 is the guide portion. The slot surfaces of the first notch slot 3011 may include a first stop surface 3011a at a lower position, a second stop surface 3011b at a higher position, and a ramp surface 3011c connected between the first stop surface 3011a and the second stop surface 3011 b. As shown in fig. 3 and 7, the water guide sleeve 4 is provided with a rod body 402 extending in the radial direction, the rod body 402 is the guide matching portion, and the rod body 402 is located above the center tube 201 and supported in the first notch slot 3011. The annular sleeve 301 may be symmetrically provided with two first notch grooves 3011, and correspondingly, the water guide sleeve 4 is symmetrically provided with two rod bodies 402, and the two rod bodies 402 are respectively located in the two first notch grooves 3011.

As shown in fig. 3, when the water guiding sleeve 4 is in the first position, the rod 402 is supported on the first stop surface 3011a, and during the rotation of the rotating shaft 3, the rod 402 reaches the second stop surface 3011b along the slope surface 3011c, so that the water guiding sleeve 4 moves to the second position, as shown in fig. 4. When the water guide sleeve 4 is in the second position, the rod body 402 is supported on the second stop surface 3011 b. When the shaft 3 rotates in the opposite direction, the rod 402 moves from the second stop surface 3011b to the first stop surface 3011a along the slope surface 3011c, and accordingly, the water guide sleeve 4 moves from the second position to the first position. First stop face 3011a and second stop face 3011b may each be a segment of a flat surface to support rod 402. The first stop surface 3011a, the second stop surface 3011b, and the ramp surface 3011c may be rounded, which may reduce friction between the rod 402 and the first notch slot 3011.
