Description

Technical Field

[0001] The utility model relates to the technical field of decoration, in particular to an electric hammer dust collection structure. Background Art

[0002] An electric hammer drill is an electric rotary hammer drill with a pneumatic hammer mechanism and a safety clutch. The hammer uses the principle of piston motion, with compressed gas striking the drill bit. This requires little manual effort and can create holes in hard materials like concrete, brick, and stone. The electric hammer is highly efficient in creating holes in these materials.

[0003] Patent publication number CN201669686U discloses an electric hammer with a dust suction device, including an electric hammer body, an exhaust fan, and a dust collecting sleeve.

The fan housing is connected to the handle. The fan impeller is driven by the electric hammer motor shaft. The dust suction hole outside the impeller is provided with a dust filter cover. The dust collecting sleeve is connected to the electric hammer housing outside the dust filter cover. A spring is fixed to the inner wall of the dust collecting sleeve, and a rubber ring is provided at the interface between the dust collecting sleeve and the drill bit.
