Description

Technical Field

[0001] The utility model relates to the technical field of oil filters for air compressors, in particular to an oil filter for air compressors. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. They need to be used with an oil filter. Oil filters generally refer to gasoline filters, and gasoline filters are referred to as gas filters. Gasoline filters can be divided into carburetor type and electronic injection type. For gasoline engines using carburetors, the gasoline filter is located on the inlet side of the oil pump. The working pressure is relatively low and a nylon shell is generally used. The filter element of the gasoline filter is mostly made of filter paper. There are also gasoline filters made of nylon cloth and polymer materials. The main function is to filter out impurities in gasoline.

[0003] In the prior art, when replacing the oil filter of an air compressor, some oil will flow out. Traditional operators need to take an additional container to collect the oil when replacing it. If they are not careful, the oil will spill all over the floor, making it impossible to recycle the waste oil. To this end, we propose an oil filter for an air compressor. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. Through the waste oil recovery mechanism, when replacing the air compressor oil filter, some oil will flow out. Traditional operators need to take an extra container to catch it during replacement, which will spill all over the floor if they are not careful. The waste oil tank can remove impurities in the oil after the leaked oil passes through the filter element, and then it can be recycled and reused, saving energy. At the same time, the handle can facilitate the installation of the oil filter.

[0013] 2. Through the auxiliary connection mechanism, the upper end threaded pipe is rotated and connected to the oil filter mounting pipe of the air compressor, and then the connecting frame is fixed to protect the oil filter mounting pipe of the air compressor. The lower end threaded pipe is tightened into the connecting port of the oil filter to protect the connecting port of the oil filter. When the oil filter is connected to the oil filter mounting pipe of the air compressor, wear caused by back and forth friction between the two is avoided, thereby increasing the service life.
