The utility model relates to the technical field of computer cleaning, aims to solve the problem that in the prior art, when an operator carries out dust removal treatment on a
computer case, a large amount of dust is prone to drifting to the outside, and the
physical health of the operator is not facilitated, and provides a
computer case dust removal device which comprises a base. A glass frame is clamped to the top of the base. A plurality of supporting rods which are parallel to one another and are distributed at intervals are arranged in the base; dust filtering assemblies are arranged at the bottoms of the multiple supporting rods, and the outer edges of the dust filtering assemblies abut against the inner wall of the cavity; an
air blower is arranged on one side of the base, an air inlet of the
air blower communicates with a cavity in the base, a
brush is arranged in the glass frame, and a ventilation channel is formed in the axis of the
brush and communicates with an air outlet of the
air blower; a first opening is formed in the side, close to the air blower, of the glass frame and connected with a dustproof cloth cover in a sealed mode. The
dust collector has the advantages that dust is not prone to drifting to the outside,
physical health of operators is benefited, cleaning efficiency is high, and operation is convenient.
