The specific implementation process comprises the following steps:

when the laser cleaning gun works, the dust suction pipeline 3 sucks dust around the focusing mirror 11. When the particle size of the dust is small, the dust is removed through the interception net 41 and the dust collection hose; when the particle size of the dust is larger, the dust will impact on the interception net 41, and the dust will fall into the dust collection box 6 under its own gravity, thereby realizing the collection of the dust with large particle size.

In the working process, the worker observes the dust accumulation condition in the dust collection box 6 through the glass plate 621, and when the dust collection box 6 is full, the worker pulls out the dust collection box 6 to pour out the dust, so that the dust collection box 6 is cleaned.
