A part of the switch 200 is disposed inside the housing 100 and connected to the stem 310, and another part of the switch is exposed from the housing 100 for easy pressing. The switch 200 is used for driving the switch base 300 to rotate. For example, once the switch 200 is pressed, the switch 200 can drive the valve rod portion 310 to rotate a predetermined angle, and since the valve rod portion 310 is fixedly connected to the switch base 300, the valve rod rotation also drives the switch base 300 to rotate a predetermined angle.

With continued reference to fig. 3, the housing 100 is formed with a structure similar to a step, the spacer 410 is disposed in the housing 100 and positioned in abutment with the step of the housing 100, the spacer 410 is provided with a pressure relief channel 411, and one end facing the switch seat 300 is provided with a second end wall 417, the second end wall 417 is provided with a third water through hole 412, and the second end wall 417 is in contact fit with the first end wall 351.

The valve seat 430 comprises an annular structure 433 and an outer valve body 434, the outer valve body 434 is connected with the housing 100, the outer valve body 434 is provided with a water inlet 435, the annular structure 433 is arranged inside the outer valve body 434, a water outlet channel 432 is defined inside the annular structure 433, a water inlet channel 431 is defined between the annular structure 433 and the outer valve body 434, and the water inlet channel 431 is communicated with the water inlet 435. The water inlet passage 431 is connected with the pressure relief cavity 401 through a pilot passage 4251, that is, water enters the water inlet passage 431 from the water inlet 435 and then enters the pressure relief cavity 401 through the pilot passage 4251. The pressure relief chamber 401 can communicate with the water passing chamber 320 through the pressure relief passage 411, and the water passing chamber 320 communicates with the water outlet passage 432 through the first water passing hole 330, the third water passing hole 412, the first water passing passage 421 and the third water passing hole 412.

Wherein the switch base 300 has a first position and a second position, and the switching between the first position and the second position is achieved by pressing the switch 200.
