dust protection device

Abstract

The invention discloses a dust protection device, which comprises a main body of an electric drill, a drill adjusting ring is connected to the electric drill main body, a drill clip is connected to the drill adjusting ring, and the electric drill main body is provided with a The dust protection device for internal dust, this dust protection device, through the cooperation of the outer shell, the first inner shell, the second inner shell and the spring, realizes the contraction function, and can be compressed with the drilling of the drill bit, and the drill bit will bring the dust into the In the casing, it prevents outward diffusion and plays a protective role. The collection ring can realize the rotation under the action of the linkage drive device, even if the drill bit is in different states, it can collect dust, so as to continuously collect dust into the collection chamber .

Description

technical field

[0001] The invention relates to the technical field of dust protection, in particular to a dust protection device. Background technique

[0002] In terms of decoration, electric drills are often used to drill holes on the wall. When drilling, a lot of lime or concrete powder will be raised, which will be directly inhaled by the operator. If this happens for a long time, it will cause diseases of the trachea or lungs, such as bronchitis. Emphysema or pneumoconiosis, etc., are often overlooked because of the transient nature of their operations. Ordinary masks are not enough to prevent dust, and dust masks are expensive and need to be replaced frequently.

[0003] Electric drill drilling is not only for drilling holes on the wall, but also sometimes on the ground, but some existing dust protection devices for electric drills or impact drills can collect dust due to gravity when drilling holes on the wall, but The dust cannot be collected when the ground is dri...
