Grading dust removal device of electronic electric appliance

Abstract

The invention relates to the technical field of electric appliance dust prevention, and discloses a grading dust removal device of an electronic electric appliance. The grading dust removal device comprises a dust removal outer cover, wherein an electric appliance heat dissipation port is fixedly installed at the top of the dust removal outer cover, sliding rails are fixedly installed at the two ends of the lower surface of the electric appliance heat dissipation port, a sliding block is movably connected to the inner portion of each sliding rail, a dustproof brush is connected to one end of each sliding block, a connecting block is fixedly installed at the axis of the dustproof brush, a handle is fixedly installed at the bottom of the connecting block, an air inlet is arranged below the dustproof brush, a fan is arranged below the air inlet, a connecting shaft is fixedly connected to the top of the fan, and blades are fixedly installed at the top of the connecting shaft. According to the grading dust removal device of the electronic electric appliance, the sliding rails, the sliding blocks and the dustproof brush are arranged, and the purpose of clearing dust accumulated at the heat dissipation port is achieved by moving the handle up and down; and the fan is arranged, the fan reversely rotates to form a reverse airflow to suck the dust raised by the dustproof brush into the dust removal outer cover, so that the purpose of secondary dust collection and dust removal is achieved.

Description

technical field [0001] The invention relates to the technical field of dust removal for electrical appliances, in particular to a classified dust removal device for electronic appliances. Background technique [0002] Dust exists in every corner. Any air flow will drive the dust to fly. When the air flow is small, the dust will fall. In daily life, there are often a lot of dust falling on electrical appliances, corners of the house and other places that are difficult to clean. The place where there is more accumulation is often the place where there are more bacteria and electrical appliances are prone to damage. The biggest reason is that the dust provides a growth environment for bacteria. Some electrical appliances burn due to poor heat dissipation. Some electronic appliances are in an outdoor environment. In order to prevent the intrusion of dust and sundries, a sealed structure is generally used. However, as the load of electronic appliances increases, the heat generate...
