Description

Technical Field

[0001] The utility model belongs to the technical field of decoration dust removal and relates to a decoration dust removal device. Background Art

[0002] During decoration, it is often necessary to drill holes in the wall. During the drilling process, large dust particles will be generated between the electric drill used and the wall, seriously polluting the indoor air environment. The existing dust removal device is to use a corrugated hose to cover the drill bit to prevent the dust particles generated by the high-speed rotation of the drill bit from splashing everywhere. After use, the dust particles in the corrugated hose can be poured out. However, in actual drilling operations, when there are more drilling requirements or the drill bit needs to be switched, when the electric drill is tilted or the corrugated hose is taken and placed, it is easy to cause the dust particles inside to pour out, resulting in air pollution.

[0003] Therefore, the utility model provides a decoration dust removal device to solve the above problems. Content of the Utility Model

[0004] In view of the problems existing in the prior art, the utility model discloses a decoration dust removal device. The technical scheme adopted is that it includes a corrugated hose. A notch is opened at the lower edge of the opening of the corrugated hose. A dust collection box is connected to the lower end of the notch. Closing mechanisms are oppositely arranged at the upper edges of the left and right inner side walls of the dust collection box. The closing mechanism includes inclined baffles oppositely arranged on the left and right. One sides of the left and right inclined baffles respectively in contact with the left and right inner side walls of the dust collection box are respectively fixedly connected with rotating shafts. The rear ends of the left and right rotating shafts penetrate through the rear side wall of the dust collection box. The rear ends of the left and right rotating shafts are fixedly sleeved with torsion springs. The other ends of the torsion springs are fixedly inserted into the rear side wall of the dust collection box. Rotating pieces are relatively stacked and sleeved on the rotating shafts at the rear ends of the left and right torsion springs. A notch is opened at the overlapping part of the left and right rotating pieces. A connecting column is sleeved in the notch. One end of the connecting column is fixedly connected with a T-shaped handle.

[0005] As a preferred scheme of the utility model, a sleeve is fixedly sleeved on the rear end opening of the corrugated hose, and a bearing is fixedly sleeved in the sleeve; by adopting the bearing, when the drill bit part of the electric drill is inserted into the bearing and rotates at a high speed, it is convenient to reduce the friction heat generation between the drill bit and the corrugated hose and improve the tolerance of the corrugated hose.

[0006] As a preferred scheme of the utility model, limiting grooves are respectively fixedly arranged on the left and right sides of the rear side wall of the dust collection box where the T-shaped handle fits; by arranging the limiting grooves, it is convenient for the T-shaped handle to move up and down along the middle of the rear side wall of the dust collection box, so that the left and right rotating pieces stacked together drive the left and right rotating shafts to rotate relatively at the same time, and then drive the left and right inclined baffles to open or close at the same time.

[0007] As a preferred embodiment of the present utility model, the other end of the connecting column passing through the notch is fixedly sleeved with a limiting ring.

[0008] As a preferred embodiment of the present utility model, a bottom cover is opened at the lower end of the dust collection box. The front side wall edge of the bottom cover is hinged to the lower edge of the front side wall of the dust collection box, and the rear side wall edge of the bottom cover is connected to the rear side wall of the dust collection box by a magic tape. By adopting the dust collection box, it is convenient to collect the dust generated by drilling. At the same time, by tearing the magic tape, the bottom cover at the lower end can be opened to discharge the dust particles inside the dust collection box.

[0009] As a preferred embodiment of the present utility model, the corrugated hose is made of transparent silica gel material. By adopting the transparent silica gel material, it is convenient to observe the drilling position when using an electric drill to drill holes.

[0010] The beneficial effects of the present utility model are as follows: By opening a dust collection box at the lower part of the front end opening edge of the corrugated hose, and arranging inclined baffles oppositely on the left and right at the upper end opening of the dust collection box, through the cooperation of the rotating shaft and the torsion spring, the middle parts of the left and right inclined baffles are squeezed to temporarily separate the corrugated hose from the dust collection box, thereby preventing the dust powder particles temporarily stored in the dust collection box from spilling out and causing secondary pollution. By pulling down the T-shaped handle, the T-shaped handle drives the rotating pieces stacked on the left and right to rotate downward simultaneously through the connecting column, drives the left and right rotating shafts to rotate simultaneously, and further drives the left and right inclined baffles to rotate downward relatively, separating the middle parts thereof, and pouring the dust particles remaining from drilling into the dust collection box. When replacing the drill bit or the electric drill tilts during use, it can also prevent the dust particles from spilling again and causing air pollution, thereby improving the convenience of use.
