Abstract

The invention belongs to the technical field of purifiers and provides a positioning drum for a filter element. The positioning drum comprises a drum body and a locking drum; the drum body is arrangedin the manner of penetrating up and down; a stepped hole is formed in an upper port of the drum body; a limiting slot is arranged in the manner of surrounding a bottom side wall of the stepped hole;the locking drum comprises a drum section on the upper side and a swelling section on the lower side; the inner diameter of the drum section is kept constant; the inner diameter of the swelling section gradually increases from bottom to top; the thickness of the side wall of the swelling section gradually reduces from bottom to top; the drum section is sleeved in the stepped hole; and the swellingsection is positioned in the limiting slot. The technical effect of simply, quickly and stably locking a filter element purifying unit can be achieved.

Description
