[0008] Preferably, the diameters of the cold water through hole, the hot water through hole and the mixing water through hole are equal, and the diameters of the mixing water outlet, the first mixing water through hole and the second mixing water through hole are equal.

[0009] Preferably, the diameters of the cold water through hole, the hot water through hole and the mixed water through hole are larger than the diameters of the mixed water outlet, the first mixed water through hole and the second mixed water through hole.

[0010] Preferably, a diameter of the third water mixing through hole is smaller than a diameter of the first water mixing through hole and a diameter of the second water mixing through hole.

[0011] Preferably, the water mixing part body and the water outlet part body are also provided with countersunk holes for valve core installation and positioning.
