Background
In the prior art, a mixing faucet is a faucet which mixes cold water and hot water together and can adjust the water temperature. The valve core of the water tap inside the water tap controls the water outlet flow, and when the water tap is used, the switch is turned on by lightly pulling the switch with hands, and then the water temperature is adjusted by rotating. With the advent of water purifiers, more and more people select a way of separating drinking water from other domestic water, for example, drinking water uses purified water purified by the water purifier, and vegetables and dishes are washed using common mixed water, i.e., raw water. This approach is clearly a great benefit to the health of the person.
