Abstract

The utility model relates to a filter cartridge dust remover convenient for filter cartridge replacement, which comprises a dust remover and a filter cartridge, wherein a mounting plate is arranged in the dust remover, air holes are formed in the mounting plate, the dust remover further comprises a lantern ring, a threaded pipe is in threaded connection with a screw rod, and a plurality of grippers are uniformly distributed along the circumference. In the undeployed state, the free end of the Z-bar remains swaged and out of contact with the mounting plate. The corner at the bottom of the Z-shaped rod is skillfully hinged on the top wall of the filter cylinder, the threaded pipe cannot rotate along with the screw rod, and only can move along the axial direction along with the driving force generated by the rotation of the screw rod, so that ascending or descending is realized. When the threaded pipe is pressed down, the corner of the Z-shaped rod is forced by the ingenious pushing of the hinge rod, so that the free end of the Z-shaped rod is forced to extend outwards through the An Ban air hole until the free end of the Z-shaped rod is tightly abutted against the upper top wall of the mounting plate. At this time, the flange at the top of the filter cylinder is tightly attached to the inner wall of the dust remover, and the handle provides strong mechanical locking force, so that the filter cylinder is effectively prevented from shaking or falling off.
