ELECTRONIC DEVICE

Abstract

An electronic device having a housing, a grating and at least a blade is provided. The housing has an opening and the grating covers the opening. The blade pivoted to the grating has many meshes. When an air current passes through the meshes, dust particles suspended in the air adhere to the meshes. After sufficient dust particles have accumulated over the meshes, the blade rotates.
