Background
The water tap is a popular name of a water valve, is used for controlling the size of water flow to be switched on and off, and has the effect of saving water. The water tap has a very fast updating speed, and develops from an old cast iron process to an electroplating knob type water tap, a stainless steel single-temperature single-control water tap, a stainless steel double-temperature double-control water tap and a kitchen semi-automatic water tap. At present, more and more consumers purchase faucets, and the faucets are comprehensively considered from various aspects such as materials, functions, shapes and the like.
With the improvement of living standard of people, the quality requirement of the water faucet is higher and higher, and in the water supply system in the south, the water supply system in the south generally mainly supplies water at normal temperature, while the water supply system in the north often also supplies hot water. Whether a south or north star hotel or a subject restaurant, its faucet will supply both cold and hot water. In the south, in order to improve the experience of customers, the water supply temperature of a toilet faucet of a partially featured subject restaurant is fixed at 38 ℃ and is approximately equal to the body temperature of a human body, so that the toilet faucet can bring comfort to the human body.
However, in the process of implementing the technical solution in the prior art, the applicant finds that the following technical problems exist in the technical solution in the prior art:
the distance between the faucet and the source of water supply is far, or the last section of the faucet often has accumulated water, the accumulated water flows out after the faucet is opened, but the temperature of the accumulated water cannot be well controlled. In addition, every summer, because the outdoor water pipe is exposed under the sun and exposed to the sun, the temperature of a certain section of water pipe is too high, and when the faucet is opened at first, the effluent water can feel hot. In winter, the situation is opposite, especially in south most of China, an independent hot water supply system is adopted, when a water tap is turned on, the temperature of the outflow water is low, and the user experience is influenced.

In examples 1 to 3, shell powder was used as a coating component, and the principle of hardening by water absorption of calcium carbonate was utilized to prevent the coating from peeling off when it meets moisture.
The temperature sensing powder added in the formula of the reversible temperature sensing discoloration coating is a crystalline substance, when the coating is heated to a certain temperature, the temperature sensing powder loses crystal water to cause the crystal form of the coating to be changed, so that the color of the coating is changed, when the coating is cooled to room temperature, the temperature sensing powder can absorb water vapor in the air, the crystal form is recovered, and the coating gradually recovers to the original color. Therefore, the temperature change can be indicated by using the characteristic that the color changes caused by the gain and loss change of the temperature sensing powder crystal water.
