Abstract

This utility model discloses a quick-release filter cartridge for lubricating oil filtration, relating to the field of filter cartridges. It includes a filter cartridge body, which is installed inside a top cover and a housing. A support connection assembly is fixedly installed on the lower inner wall of the housing. The support connection assembly consists of a connecting base plate, a circular support plate, a ring, and a first magnet. Several connecting base plates are fixedly installed in a ring on the outer wall of the circular support plate, and the ring is fixedly installed at the upper end of the circular support plate. Several first magnets are fixedly installed in a ring on the outer wall of the ring. By setting a connection and fixing assembly consisting of a connecting column, an arc-shaped base plate, and a second magnet on the filter cartridge body, and a support connection assembly consisting of a connecting base plate, a circular support plate, a ring, and a first magnet inside the housing, the convenience and efficiency of replacing the filter cartridge body are significantly improved, effectively solving the problems of difficult disassembly, low efficiency, and easy jamming and damage associated with traditional threaded fixing methods.
