Dust collection device for indoor decoration punching

Abstract

The invention discloses a dust collection device for indoor decoration punching, which belongs to the technical field of decoration environmental protection and comprises a fixed sleeve, a movable sleeve, fan blades, a sealing suction ring, an annular baffle, a dust collection box, wherein the fixed sleeve and the movable sleeve are coaxially arranged and slidably connected with a drilling head, and the fan blades are mounted on a rotating shaft and are arranged in the fixed sleeve; the sealing suction ring is coaxially mounted at one end, far away from the fixed sleeve, of the movable sleeve, the annular baffle is coaxially installed at the end, away from the sealing suction ring, of the inner circumferential face of the movable sleeve, an annular gap is formed between the inner circumferential face of the annular baffle and the outer circumferential face of the rotating shaft, and the dust collection box is arranged at the bottom of the movable sleeve and the bottom of the fixed sleeve and is in sliding connection with the movable sleeve and fixedly connected with the fixed sleeve. The fixed sleeve is fixedly installed on the shell, and a plurality of filtering through openings are formed in the middle of the annular baffle. The device is small in size, convenient to hold for working, simple in structure and convenient to operate; the device can be tightly adsorbed on a wall body, so that the drilling head is vertical to the wall body and does not deviate; dust in the atmospheric environment is reduced, and the environment quality is improved.

Description

technical field [0001] The invention relates to a dust suction device for drilling holes for indoor decoration, which belongs to the technical field of decoration and environmental protection. Background technique [0002] Indoor decoration is carried out in areas and ranges such as walls and ceilings. When installing wall lamps, closets and other wall-mounted objects, electric drills are generally used to drill holes in the walls. The dust raised during the drilling process is easy to be inhaled The human body affects the health of the decoration personnel, so a vacuum device will be used for dust removal. Some existing dust collection devices are large in size, inconvenient to move, complex in structure, and inconvenient to operate; there is a gap between the existing dust collection devices and the wall during the drilling process, and some dust floating affects the breathing of the staff, or sinks Falling on the ground increases the cleaning intensity; some vacuum devic...
