The waterway plate 10 comprises a plate body 12 and a connecting pipe 11 penetrating the plate body 12, and a water inlet 111 is formed in the connecting pipe 11 for connecting a filter bottle. The valve cover 30 is connected to the waterway plate 10 and located at one end of the connecting pipe 11, and a water passing hole 311 is arranged on the valve cover 30. The water stop assembly comprises a valve rod 20 and an elastic member 40. The valve rod 20 is slidably arranged in the connecting pipe 11, and one end of the valve rod 20 is capable of cooperating with the valve cover 30. The elastic member 40 elastically connects the valve rod 20 and the waterway plate 10. The elastic member 40 is used to drive the valve rod 20 to move away from the valve cover 30, so as to block the connecting pipe 11 by the valve rod 20, and the valve rod 20 is capable of cooperating with the valve cover 30 to limit the position of the valve rod 20, thereby avoiding the valve rod 20 from being separated from the connecting pipe 11 under the elastic force.

[0042] In the embodiment, the valve cover 30 is arranged to limit the position of the valve rod 20 at each water inlet 111, thereby avoiding the valve rod 20 from being separated from the valve cover 30.

When the valve rod 20 penetrates the valve cover 30, the elastic arms 212 are pressed to make the elastic arms 212 clamp the hole in the direction of the center of the valve rod 20, thereby reducing the cross-sectional size of the end of the valve rod 20 provided with the abutting portion 213, so that the valve rod 20 can smoothly penetrate the center hole. After the elastic arms 212 are released, the elastic arms 212 are reset, and the abutting portion 213 is capable of abutting with the outer wall of the valve cover 30, thereby achieving the purpose of limiting the position of the valve rod 20.
