[0036] The working principle of this utility model:

[0037] When it is necessary to clean the dust on the surface of the support plate 203, the exhaust fan 211 is started to extract the gas in the air supply ring pipe 213 through the connecting pipe 212, so that the exhaust pipe 204 extracts the dust on the top of the support plate 203, and the dust enters the exhaust pipe 204 and is intercepted by the dustproof net 214;

[0038] Secondly, when it is necessary to collect the dust on the top of the dustproof net 214, first remove the connecting pipe 212, then turn the knob 216 to drive the threaded rod 217 to rotate, and the threaded sleeve 219 is locked by the inner limit block of the connecting groove 210 and cannot rotate with it, so that the threaded sleeve 219 moves upward along the length direction of the threaded rod 217, and the threaded sleeve 219 pushes the extrusion piece 220 to lift up and engage with the bottom of the snap-on round head 218. During this period, the upper end of the extrusion piece 220 pushes the clamping blocks 221 on both sides. The clamping blocks 221 are subjected to the horizontal force to compress the spring 222 and are retracted into the support plate 203. The clamping block 221 no longer supports the snap-on round head 218, and then the connecting piece 215 and the air supply ring pipe 213 can fall and separate from the bottom of the support plate 203.

[0039] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
