Dust removal ring of electric hand drill

Abstract

The invention relates to a dust removal ring of an electric hand drill. The dust removal ring of the electric hand drill mainly comprises a rotary ring and a hollow-inside dust collection ring, the dust collection ring is sleeved with the outer peripheral wall of the rotary ring, and the outer peripheral wall of the rotary ring is formed of a hard dustproof mesh. A rubber ring is attached to the inner peripheral wall of the rotary ring, and the internal diameter of the rubber ring is matched with the size of an electric hand drill bit. Centrifugal holes extending along the rotary ring axially are distributed on the circumference of the rotary ring at equal distance, the centrifugal holes penetrate the rubber ring and the outer peripheral wall of the rotary ring and communicated with the internal cavity of the dust collection ring, and the diameter of the centrifugal holes is not smaller than the width of a threaded groove of the drill bit. The dust removal ring is simple in structure, convenient to mount and free of external power source, chippings and dust of drill holes can be efficiently collected, and dust can be prevented from polluting the environment.

Description

technical field [0001] The invention relates to a hand electric drill accessory, in particular to a dust removal ring. Background technique [0002] Electric hand drill, a hand-held electric tool, is one of the best-selling products in the electric tool industry. It is widely used in construction, decoration, furniture and other industries; during drilling operations, the electric hand drill drives the drill bit into the wall or furniture , with the rotation of the drill bit, the debris of the wall or furniture is pulled out by the drill bit. Due to the small particle size of the debris, it floats in the air after flying out of the drill hole and seriously affects the health of the operator. It will pollute the wall, furniture, floor, etc.; some of the common dust removal accessories place a collection tank under the drill hole. This structure cannot solve the problem of debris floating and entering the respiratory tract, and it will also pollute the drill hole with dust Ne...
