[0037] Furthermore: the external air entering the main shell 3 contacts the dust detector 2103 through the air pipe 2102, so that the dust detector 2103 can measure the approximate dust content in the air entering the main shell 3 with a small error, and the external air after passing through the dust detector 2103 is filtered by the filter element 2202, so that the dust and other impurities in the external air are adsorbed in the filter element 2202, so that the dust in the air will not continue to be discharged into the air to cause secondary pollution to the external air, and the staff only needs to move the pull rod 2306 to drive the front and rear side clamping rods 2304 to move to complete the disassembly and assembly of the closing frame 2203, which is convenient for the staff to replace the filter element 2202.

The air passing through the filter element 2202 is filtered by the filter element 2202, so that the internal dust stays in the filter element 2202, so that the air discharged from the main shell 3 does not contain dust impurities.
