Dust bag positioning cylindrical member for a two-stage dust collecting machine

摘要

A dust bag positioning cylindrical member for a two-stage dust collecting machine is a cylindrical shape with an open upper end and an open lower end with a diameter a little less than that of a bag cylinder so that the dust bag positioning cylindrical member may be placed in and stabilize a dust bag previously placed in the bag cylinder. Thus the dust bag may not be blown to stick at the mouth of a first air exit during a second stage of dust collecting operation of the machine.
