Electric heater control circuit, electric heater control circuit board and electric heater

The utility model relates to an electric heater control circuit, an electric heater control circuit board and an electric heater, and the circuit comprises a temperature detection circuit, a driving switch circuit, a main control module, a communication module, a man-machine interaction module and a power module. The temperature detection circuit can collect the current internal temperature; the main control module can receive the current internal temperature and can also control the on-off of the first driving switch sub-circuit; the first driving switch sub-circuit controls on-off of the heating load, and the second driving switch sub-circuit controls on-off of the fan. The user terminal can be in communication connection with the main control module through the communication module, the user terminal can remotely control the main control module to work, then the heating function can be started, and the temperature in a set area is raised in advance. According to the electric heater, the man-machine interac
