More Information
Summary:A bearing secondary dustproof structure for a dedusting electric tool is characterized in that a bearing hole at the front end of a casing is connected with a bearing, the bearing is connected with a rotor spindle, the end face of an inner ring of the bearing, dustproof gaskets and upper and lower planes of a T-shaped gasket are concentrically connected in sequence, a space formed by the T-shaped gasket and the dustproof gaskets is filled with a dustproof pad, and the T-shaped gasket is connected with a plane of a dust collection fan. The dust collection fan is located in a cavity formed by connecting an upper outer cover and a lower outer cover of the dust collection fan, more than 99% of dust is discharged from a dust outlet through negative pressure generated in the cavity, less than 1% of dust is blocked by an upper plane of the dustproof gasket when passing through a gap between the T-shaped gasket and the dustproof gasket, and airflow changes the direction of the dust and is discharged through a space b
