[0017] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0018] 1. The valve core is sealed by pressing against the installation plane of the diverter valve seat. Under this sealing method, it can withstand high water pressure and flow;

[0019] 2. The water valve housing is provided with two water outlet channels, and the diversion valve seat also includes a diversion channel connecting the two water outlet channels. The water outlet space is connected to one of the water outlet channels, and the water flows through one of the water outlet channels and then flows to the other water outlet channel through the diversion channel.

[0022] 5. The connecting and fixing bracket is used to fix the water valve housing and fix the water valve housing to the wall. The water valve housing is separated from the connecting and fixing bracket, and the water flow and force-bearing functions are separated. The water valve housing flows water but does not bear the installation and fixing force. The connecting and fixing bracket bears the installation and fixing force inside and outside the wall without flowing water. The advantage of the split type over the integrated type is that it prevents the situation where only one part is damaged and the entire body needs to be replaced. In addition, it prevents the water valve housing from being damaged by the installation and fixing force.

[0023] 6. The bottom plate is fixedly connected to the wall, and the connecting and fixing bracket is snap-connected to the bottom plate and clamps the water valve housing against it, making installation quick and easy;

[0024] 7. The water valve housing, diverter valve seat, connecting and fixing bracket and bottom plate are all assembled structures and can be made of all plastic materials to avoid the use of lead-containing materials and avoid harm to the human body.
