[0022] When the device is in use, the dust collector head 9 is first placed according to the dust reduction position, the water in the water tank 1 is pumped by the water pump 2, and the water is sprayed through the nozzle 5 to reduce dust. At the same time, the exhaust fan 7 is started, and the wet dust is sucked away through the dust collector head 9 to prevent secondary dust. The dust enters the filter box 6 through the dust collection pipe 8 and the dust channel 19 and is intercepted, completing the dust reduction process.

[0023] In this embodiment, the dust collection duct 8 includes a plurality of hard ducts 10, and the plurality of hard ducts 10 are connected to each other through a bellows. The design of the bellows can make the arrangement of the hard ducts 10 more flexible.
