[0007] Beneficial effects: The optical sensor can detect the thickness of dust on the surface of the heating element, the airflow sensor can detect the ventilation efficiency through the heating element, and the power monitoring module can detect whether the power fluctuation of the heating element is abnormal. If the dust thickness on the surface of the heating element is thick, or the ventilation efficiency through the heating element is low, or the power fluctuation of the heating element is abnormal, it meets the cleaning conditions.

[0008] In one optional embodiment, the detection device includes an optical sensor, an airflow sensor, and a power monitoring module, and the optical sensor, airflow sensor, and power monitoring module are integrated into one unit. The electric heater includes a heating bracket, and the heating element and the detection device are all disposed on the heating bracket.

[0021] Beneficial effects: The detection device includes an optical sensor that detects the thickness of dust on the heating element surface. The dust thickness information indicates the level of dirt. When the dust thickness exceeds a first preset value, the cleaning device automatically activates, removing dust from the heating element surface and preventing excessive dust accumulation from affecting the heater's thermal efficiency. This eliminates the need for manual cleaning by the user, improving the user experience. Alternatively, the detection device includes an airflow sensor that detects the ventilation efficiency through the heating element. The ventilation efficiency information indicates the level of dirt.

When the level of dirt meets the cleaning criteria, the ultrasonic generator vibrates and dislodges the dust from the heating element's surface. Simultaneously, the fan operates, blowing the dust to the outside of the heater. Furthermore, the ultrasonic generator's operation does not interfere with the normal operation of the heater, allowing for cleaning of the heating element while the heater is running.
