When the pressing pipe 520 is released, that is, after the external force is removed, the return spring 540 returns the pushing rod 530 and the pressing pipe 520 integrally, the pushing rod 530 and the pressing pipe 520 are both far away from the rotating member 420, because the return spring 540 applies an upward acting force to the pushing rod 530, and the indexing pawl 531 loses the limit of the guide groove 512, the guide surface three 5311 on the indexing pawl 531 slides to the guide surface one 5111 along the guide surface two 5211, and then the indexing pawl 531 slides to the adjacent guide groove 512 along the guide surface one 5111, so that the indexing pawl 531 is positioned above the highest point of the guide surface five 4211 again, and the guide surface three 5311 on the indexing pawl 531 abuts against the guide surface two 5211 of the clamping pawl 521 in the guide groove 512 again, thereby facilitating the next switching.

The outlet water temperature is controlled by the adjusting component 300, the water diversion component 400 switches the water outlet channel 230, so that only one water using device is used for water outlet in single adjustment, and the purposes of conveniently adjusting the water temperature and controlling water diversion of the valve core are achieved.

The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims.
