Description

Technical Field

[0001] The utility model relates to the technical field of old building reconstruction, in particular to a wall dust cleaning device for old building reconstruction. Background Art

[0002] The development of a city is a dynamic process of continuous renewal and change. In this process, many historical buildings have been demolished in blocks, streets and neighborhoods. This constructive destruction has threatened the compatibility and continuity of the urban form. At this time, the old building renovation technology began. The renovation included the improvement of the building's space, the application of new components and materials, and the curtain wall formal facade adapted to the local terrain.

[0003] The utility model patent with authorization announcement number CN216702472U discloses "A wall cleaning device". The user holds the handle of the device and starts the motor, so that the motor drives the cleaning disc to rotate, and the cleaning disc drives the second cleaning brush to rotate. At this time, the second cleaning brush contacts the wall, thereby cleaning the wall. At the same time, the rotating cleaning disc drives the cleaning ring to rotate through the connecting block, and the cleaning ring drives the first cleaning brush to rotate. When cleaning to the corner of the wall, the rotating first cleaning brush cleans the corner of the wall to prevent the corner of the wall from being not thoroughly cleaned during cleaning, thereby improving the cleaning effect of the device.

[0004] However, the above-mentioned prior art solutions still have the following shortcomings: first, when using the wall cleaning device, the user is required to hold the device handle and start the motor, and the first cleaning brush and the second cleaning brush are driven by the motor to clean the wall. The user will consume a lot of physical strength to complete the entire cleaning work, and it is not suitable for cleaning larger walls. Secondly, although the dust on the wall can be cleaned well by the first cleaning brush and the second cleaning brush, the dust is very light and is easily blown up after being swept by the brush. The dust flying in the air not only has adverse effects on the health of the staff and the environment, but may also re-adhere to the wall, and the cleaning effect is general. Utility Model Content
