The electric water heater faucet is equipped with a heating cavity and an electric appliance control cavity, separated by a sealing plate. The electric appliance control cavity is provided with a heating circuit, and the heating cavity is provided with a heating tube. The heating tube power is generally 2-3KW, 3-5 seconds The hot water can be heated by the clock, and the heating tube is connected to the heating circuit, characterized in that the heating tube is an insulating heating tube; the insulating heating tube is a hydroelectric isolation insulating heating tube; most of the faucet bodies are high temperature resistant engineering plastic type, a few All metal type; insulated water pressure switch is installed in the control cavity of the electrical appliance. The heating circuit is provided with an electrical switch, which is connected to the end of the insulated water pressure switch to turn on and off the water and electricity. There is a temperature controller and anti-dry burning device, and a leakage protection switch can also be provided. After tap water enters the electric faucet through the valve core, it pushes the floating magnetic or water pressure switch. Under the action of water pressure, the floating magnetic or water pressure switch turns from open to closed, thus turning on the power supply. At the same time, it begins to heat and transfer heat to the tap water in the faucet, so that the tap water comes out of the faucet is hot water. If the spool is turned off or cold water is turned on, the internal floating magnet or water pressure switch will not start, the circuit is disconnected, the indicator light does not light, and the heating tube will not heat.
