In this embodiment, when the pressure relief hole 40 is in the open state, the water inlet 101 is communicated with the first water outlet 102; when the pressure relief hole 40 is in a closed state, the water inlet 101 is communicated with the second water outlet 103. The reason is that when the pressure relief hole 40 is in an open state, the water pressure in the back pressure cavity 30 is rapidly reduced, so that the water pressure in the water inlet cavity is greater than the water pressure in the back pressure cavity 30, the water stop diaphragm 601 is pushed open, the first opening 501 is opened, the second opening 502 is closed, external water flows enter from the water inlet 101 and then sequentially flow into the first cavity 201 and the second cavity 202, and finally flows out from the first water outlet 102; when the pressure relief hole 40 is in a closed state, the supporting plate 6021 and the water stop membrane 601 are further pushed to move downwards under the action of the elastic element 80, the first opening 501 is closed, and the second opening 502 is opened, so that external water flows into the first cavity 201 after entering from the water inlet 101 and flows out from the second water outlet 103.

In this embodiment, a support plate 6021 is disposed at one end of the sliding rod 602 to support the water stop membrane 601, and a thin water column 6022 is disposed at a position of the support plate 6021 corresponding to the thin water hole, and the thin water column 6022 passes through the thin water hole.
