Lubricating oil reflux structure for compressor

The utility model discloses a lubricating oil refluxing structure for a compressor. The utility model is mainly composed of members, such as an oil storing barrel, a floating ball, a floating lever, a spring, two latches, a bottom cover, etc., wherein, the floating ball drives the floating lever to make straight-line floatation, and the volume of the oil storing barrel is shrunk to minimum so that the oil storing barrel can be applicable to a minitype refrigerating air conditioning system. When gas cooling mediums which are mixed with the lubricating oil enter the oil storing barrel, refrigeration oil falls into an oil storage tank so that the floating ball which floats on the liquid level of the lubricating oil rises, and therefore, the pointed end of a butting needle at the bottom end of the floating lever is driven to disengage from an oil outlet. The spring can enhance the floating sensitivity of the floating ball, and the lubricating oil can be recovered into the compressor.
