Dust protection device

Abstract

The invention discloses a dust protection device. The dust protection device comprises an electric drill main body, wherein a drill bit adjusting ring is connected to the electric drill main body; a drill chuck is connected to the drill bit adjusting ring; and a dust protection device body capable of collecting internal dust in various states is arranged on the electric drill main body. Accordingto the dust protection device, a contraction function is realized through cooperation of a shell, a first inner shell, a second inner shell and a spring, compression can be realized along with drilling of a drill bit, and the drill bit brings the dust into the shell, so that outward diffusion of the dust is prevented, and a protection effect is achieved. In addition, a collecting ring can rotate under the action of a linkage driving device, and can collect the dust even though the drill bit is in different states in order to collect the dust into a collecting cavity continuously.

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...

[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 due to 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 drilled, the dust only enters the protective device, and cannot be collected uniformly during the whole process and at the end, resulting in leakage from the protective device when not in use
