In this embodiment, the main control circuit board can drive the dust removal component to clear the dust on the dust filter according to the ambient temperature information fed back by the temperature sensor and at the same time drive the air intake fan to blow out the dust to the external environment. The ambient temperature is detected by the temperature sensor. When the ambient temperature is lower than the set temperature, the motor will drive the brush to clean the dust on the dust filter. At the same time, the air intake fan reverses to blow air toward the outside to blow the cleaned dust out of the air intake channel of the outdoor electronic products, thereby achieving the automatic dust removal function for the dust filter. The structure is simple and stable, and there is no need for manual cleaning of the dust filter on a regular basis, which reduces the use of manual labor, saves time and effort, and is simple, greatly improving the user experience.
