1. The faucet quick electric water heater includes a faucet body and a heater. The upper and lower ends of the heater are respectively provided with an upper cover and a lower cover. The lower cover is provided with a water inlet, which comprises a cold water inlet and a hot water inlet. The cold water inlet is communicated with the 1 water outlet pipe, and the hot water inlet is connected with the 1 water inlet pipe.

2. 1 The outlet pipe is equipped with a temperature sensor to detect the temperature, and 1 The inlet pipe is equipped with a Hall flow sensor to detect the hot water inlet flow. The temperature sensor and the Hall flow sensor are respectively connected with a constant temperature control circuit for constant temperature control, and the constant temperature control circuit comprises a silicon controlled rectifier adjusting circuit.

3. Through the cooperation of the temperature sensor and the Hall flow sensor, and through the constant temperature control circuit, the power heating of the electric heating wire is controlled, so as to ensure that the outlet water temperature is in a constant temperature heating state and avoid excessive temperature and power consumption.
