Carry out the entire cleaning process. However, turning on the bathroom lighting needs to consume extra electric energy, which will not only increase the family's electricity bill, but also be unfavorable for energy saving. In addition, when washing hands with a faucet with hot water, in order to avoid scalding or catching a cold caused by overheating or overcooling of the water, people usually use their fingers to test the temperature of the water from the faucet before washing their hands, until the hands feel that the water temperature is suitable. Hand washing is clean, therefore, people can not clearly know whether the temperature of tap water is suitable for washing hands now when washing their hands.

Because existing faucets usually only have the basic function of showering, the function is relatively single, and with the continuous improvement of living standards, faucets with only a single water function can no longer meet the needs of people whose quality of life is constantly improving.
