When the solar water heater or the water heater needs to be supplied with water, the second ceramic valve plate 28 is rotated to enable the first arc-shaped groove 281 of the second ceramic valve plate 28 to cover the cold water inlet hole 7 and the hot water inlet hole 8, then the water supply function of the solar water heater or the water heater is realized through the cold water pressure of the cold water input pipe 2, and the water supply pressure is large and the speed is high.

When pure hot water is needed, when the fourth ceramic valve plate 33 is rotated to enable the second arc-shaped groove 331 to cover the hot water hole 13 and the water outlet hole 15, hot water in the hot water inlet hole 8 is conveyed into the hot water hole 13 through the hot water guide pipe 81 and the hot water inlet pipe 131, then enters the water outlet hole 15 through the second arc-shaped groove 331, and then pure hot water is output through the water outlet pipe 30.

When pure cold water is needed, the fourth ceramic valve plate 33 is rotated to enable the second arc-shaped groove 331 to cover the cold water hole 14 and the water outlet hole 15, the cold water in the cold water inlet hole 7 is conveyed into the cold water hole 14 through the cold water guide pipe 71 and the cold water inlet pipe 141, then enters the water outlet hole 15 through the second arc-shaped groove 331, and then the pure cold water is output through the water outlet pipe 30.

For those skilled in the art, based on the teachings of the present invention, changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
