Title:
NEGLECTED INSTALLATION DETECTION MECHANISM FOR FILTER ELEMENTS OF DUST COLLECTOR AND DUST COLLECTOR
Document Type and Number:
WIPO Patent Application WO/2022/100558
Kind Code:
A1
Abstract:
A neglected installation detection mechanism for filter elements of a dust collector and a dust collector. The neglected installation detection mechanism comprises: a front filter element (10) and a rear filter element (20), which abut against each other after being correctly installed and can be disassembled separately; and a neglected installation preventing assembly (30) located on the top of the rear filter element (20). After correctly installed, the rear filter element (20) and the front filter element (10) press against the neglected installation preventing assembly (30) together and trigger the neglected installation preventing assembly (30). The front filter element (10) and the rear filter element (20) are assembled separately, and the non-integrated structure facilitates the replacement of the front filter element (10) or the rear filter element (20); the neglected installation preventing assembly (30) arranged on the top of the rear filter element (20) can detect the neglected installation of the front filter element (10) and/or the rear filter element (20); when the installation of one of the front filter element (10) and the rear filter element (20) is neglected, the neglected installation of either one can be detected by only the neglected installation preventing assembly (30); and the structures of the front filter element (10) and the rear filter element (20) are improved, which can effectively prevent opposite installation of the front filter element (10) and the rear filter element (20).
