Abstract
A filtering device, including: a filter layer, where the filter layer is enclosed into a cylindrical structure; a support frame includes at least one support ring arranged at the end of the cylindrical structure, the support ring is provided with a plurality of elastic connection portions and a plurality of support ring segments, and two adjacent support ring segments are connected by using one elastic connection portion; the elastic connection portion is capable of being elastically deformed when subjected to an external force and capable of restoring by using its own elastic force; when the elastic connection portion is elastically deformed, an angle at which the end portions of the two adjacent support ring segments are connected changes, which drives a shape of the filter layer to change synchronously; when the elastic connection portion restores, the angle changes, which drives the filter layer to restore to an original shape.
