At this time, the water outlet hole 5 is connected with the water inlet hole 4 and the lower water outlet hole 8; when the water outlet hole 5 of the rotating ceramic plate is connected with the water inlet hole 4 of the fixed ceramic plate 2, it is in a closed state, and at the same time, the upper drainage hole 7 of the rotating ceramic plate 3 and the lower drainage hole 6 of the fixed ceramic plate 2 are also always in a connected state, so as to automatically discharge the residual water in the water pipe, and the residual water in the water pipe is quickly discharged without continuous dripping, and there will be no freezing and cracking of the water outlet pipe at extremely low temperature, and the scaling problem caused by the residual water not being discharged from the silicone water outlet of the top spray and hand-held showerhead will not occur, and the use effect is good.

[0025] A bottom plate 9 is installed at the bottom of the shell 1 to facilitate the installation of parts in the shell 1. An inner water sealing ring 10 is provided at the connection between the bottom plate 9 and the fixed ceramic sheet 2 to improve the sealing and waterproofness of the connection between the bottom plate 9 and the fixed ceramic sheet 2. An outer water sealing ring 25 is provided at the bottom of the bottom plate 9 to improve the sealing and waterproofness of the valve core installation.

[0034] The present invention has a simple structure and smooth water discharge. The upper drainage hole 7 is designed to be U-shaped, and its purpose is that when the rotating ceramic plate 3 is rotated to communicate with the lower water outlet hole 8, the other end of the upper drainage hole 7 (U-shaped) is communicated with the water outlet of the fixed ceramic plate 2, and the residual water in the pipe will pass through the water diversion valve core and be automatically discharged first; conversely, when the two-function water diversion valve core is rotated to the other direction, it has the same effect; then when the water outlet hole 5 of the rotating ceramic plate 3 is communicated with the water inlet hole 4 of the fixed ceramic plate 2, it is in a closed state. At this time, the upper drainage hole 7 (U-shaped) of the rotating ceramic plate and the lower drainage hole 6 of the fixed ceramic plate 2 are also always in a communicating state. According to the common sense that water flows to a lower place, the gravity of the water itself, and the constant suction principle of the vacuum in the pipe, the residual water in the water pipe is automatically discharged, avoiding the residual water in the water pipe from dripping continuously because it is not discharged, the phenomenon of the water outlet pipe freezing and cracking at extremely low temperatures, and the scaling caused by the residual water not being discharged.
