A dust-proofing method is for use in an electronic device having a housing, a heat-generating component, and a dust-proofing mechanism. The housing includes an air vent. The dust-proofing mechanism includes a shielding plate for shielding or opening the air vent, and an actuating unit for driving movement of the shielding plate. The dust-proofing method includes: causing the actuating unit to drive movement of the shielding plate to open the air vent upon detecting that the temperature of the heat-generating component has risen to a first preset temperature; and causing the actuating unit to drive movement of the shielding plate to shield the air vent upon detecting that the temperature of the heat-generating component has dropped to a second preset temperature lower than the first preset temperature. Thus, dust accumulation in the electronic device can be effectively reduced, and heat dissipation efficiency can be enhanced.
