When the first water outlet part 20 is required to discharge water, the first electromagnetic valve 26 is controlled to open the water outlet channel 202 of the first water outlet valve body 201; when water is required to be discharged from the second water outlet portion 30, the second electromagnetic valve 36 is controlled to open the water outlet passage 302 of the second water outlet valve body 301.

Wherein, a flow stabilizing block 25 is further arranged in the water outlet channel 202 of the first water outlet part 20. So that the first water outlet portion 20 can keep stable water outlet under a certain water pressure; the second water outlet part 30 is not provided with a flow stabilizing block, so that the design ensures that the valve body has a fixed-flow water outlet (namely the first water outlet part 20) which does not change along with the pressure and a water outlet (namely the second water outlet part 30) of which the flow rate is changed linearly along with the inlet pressure under the condition that the inlet pressure is changed continuously, thereby greatly increasing the application range of the valve body for a user to select.

Further, in the first water outlet portion 20, the first fixing seat 22 and the first limit stop 23 are hermetically assembled in the water outlet channel 202 of the first water outlet valve body 201 of the first water outlet portion 20, the first fixing seat 22 and the first limit stop 23 jointly enclose to form an accommodating cavity, the flow stabilizing block 25 is assembled in the accommodating cavity to realize the assembly of the flow stabilizing block 25, and the first fixing seat 22, the flow stabilizing block 25 and the first limit stop 23 are provided with water passing holes communicated with each other.
