A hinge cleaning mechanism for ultra-low temperature refrigerators

Abstract

This utility model relates to the technical field of cleaning mechanisms, specifically a cleaning mechanism for a cryogenic freezer hinge. It includes a handle, a memory metal tube at the top of the handle, a cylindrical shell at the top of the memory metal tube, a micro motor inside the cylindrical shell, and the output end of the micro motor connected to the bottom end of a rotating rod. A quick-release brush sleeve is detachably mounted at the top of the rotating rod, with several bristles evenly distributed around its periphery. A nozzle and a suction pipe are respectively mounted on the outer walls of both sides of the cylindrical shell. The nozzle is connected to an external infusion device, allowing cleaning fluid to be sprayed onto the bristles for cleaning. The suction pipe is connected to an external vacuum cleaner, allowing dust generated during brush operation to be absorbed and collected. The memory metal tube and handle facilitate adjustment of the position and orientation of the quick-release brush sleeve, enabling cleaning in narrow areas and enhancing its practicality.
