It can be seen that the valve core 22 and the valve body 21 which realize the above functions have the advantages of simple structure, convenient installation and the like.

The valve core 22, the movable cavity 214, the water inlet 211, the first water outlet 213 and the second water outlet 212 may be specifically configured as follows: the valve core 22 and the movable cavity 214 both extend along a straight line, the first water outlet 213 and the second water outlet 212 are arranged at intervals along the extending direction of the movable cavity 214, and the connecting line direction between the first water outlet 213 and the second water outlet 212 and the extending direction of the water inlet 211 are staggered.

When the valve core 22 reciprocates along the extending direction of the movable cavity 214, the water inlet 211 is always communicated with the water passing cavity 215, and when the first water outlet 213 is communicated with the water passing cavity 215 in the motion process of the valve core 22, the second water outlet 212 is not communicated with the water passing cavity 215; when the second water outlet 212 communicates with the water passing chamber 215, the first water outlet 213 does not communicate with the water passing chamber 215.
