Description

Technical Field

[0001] The utility model relates to the technical field of dust collection devices, and more specifically, to a dust collection device and a hammer drill. Background Art

[0002] A hammer drill is an electric rotary hammer drill equipped with a pneumatic hammering mechanism and a safety clutch, mainly used for drilling holes in hard materials such as concrete, bricks, and stones. The hammer drill compresses gas through piston movement to impact the drill bit to achieve the drilling operation. This design enables the operator to drill holes easily without applying too much force. The hammer drill has a high efficiency in opening holes in these materials, and the aperture range is generally 6 to 100 millimeters. During the use of the hammer drill, a large amount of dust is generated during drilling, which not only affects the working environment but also may pose a hazard to the health of the operator.
