Title: FILTERING ASSEMBLY, FILTERING DEVICE, AND DUST COLLECTOR
Abstract:
A filtering device (3) for a dust collector, comprising a dust filtering railing (4), a filtering barrel (92) which sleeves the outer side of the dust filtering railing (4), and an end cap (6) connected to one end of the filtering barrel (92). A through end hole (60) is formed in the end cap (6). A middle column (40) which passes through the end hole (60) is provided at the end of the dust filtering railing (4) corresponding to the end cap (6). The filtering device further comprises a cover body (7) mounted on the outer side of the end cap (6). The end cap (6) is provided with a plurality of clamping members (61) for abutting against the middle column (40). When the cover body (7) rotates around the middle column (40) along a rotation direction, the cover body (7) pushes each clamping member (61) to move toward the middle column (40) so that the middle column (40) is clamped by the plurality of clamping members (61). According to the filtering device, during the rotating process of the cover body (7), the cover body (7) pushes the clamping members (61) to move toward the middle column (40) gradually and finally clamp the middle column (40), so that a good fixing effect on the middle column (40) is achieved and the fixation is convenient and quick; and the state that the clamping members (61) on the end cap (6) abut against the cover body (7) and the middle column (40) can be formed, so that mutual fixation between the cover body (7) and the end cap (6) is facilitated.
