[0038] Based on the above embodiments, it is further proposed that a through-hole 23 be provided on the water transfer valve seat 2, and the cold water inlet pipe 5 is inserted and matched with the through-hole 23.

[0039] Specifically, during the process of connecting the valve core seat 1 and the cold water inlet valve seat 3, the cold water inlet pipe 5 interlocks with the through hole 23 on the outlet water transfer valve seat 2, thereby improving the coaxiality and connection stability of the three components.

[0040] Based on the above embodiments, it is further proposed that slot 1 24 is provided on both sides of the outlet water transfer valve seat 2, and slot 2 18 and slot 3 33 are respectively provided on the side of the valve core seat 1 and the cold water inlet valve seat 3 facing the outlet water transfer valve seat 2.
