After the fan 304 is started, the air inside the air bin 301 can be extracted through the input pipe. The output pipe 305 is fixedly connected to the outer wall of the fan 304.
[0027] By setting up the air bin 301 and the output pipe 305, the fan 304 can be started to extract the air inside the air bin 301 through the input pipe, so that the external gas carries the dust into the air bin 301, and is discharged through the output pipe 305 under the action of the fan 304, thereby achieving the dust removal effect.
