Purification device and clean room

The invention relates to the field of air purification, in particular to a purification device and a clean room. The device comprises an air duct and a vibration dust removal mechanism, a fan is arranged in the air duct, and two movable channels are symmetrically arranged at the top of the air duct; the oscillating dust removal mechanism comprises two mounting shafts, mesh cylinders coaxially arranged on the two mounting shafts respectively, a flexible filter screen wound on the two mesh cylinders and a driving mechanism used for driving the two mounting shafts to alternately move a and b, and when one mounting shaft is in the moving a state, the other mounting shaft is in the moving b state; wherein in the motion a, one mounting shaft rotates and revolves forwards around the other mounting shaft, or revolves backwards only around the other mounting shaft; and b, when the mounting shaft rotates and revolves forwards to wind the flexible filter screen, the other mounting shaft rotates and unwinds the flexible
