Description

Technical Field

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

[0002] Existing air compressors are mainly used to compress air or gas to a higher pressure level and store it in a compressed air storage tank for subsequent use. They are widely used in various industrial and commercial applications. However, when they are used, the exhaust pipe of the air compressor does not have a filter membrane, and cannot filter the oil in the air sprayed by the air compressor. This oil-gas mixed air may cause damage to equipment and tools using air, especially for applications requiring pure air; or the filter components cannot be self-cleaning, and oil will accumulate in the pipeline, requiring more frequent cleaning and maintenance, increasing maintenance costs and downtime. For example, a Chinese patent discloses an "air compressor" with an application number of "202121935689.9". This device includes a shell, and a filter device for gas filtering is provided on one side of the shell. By setting a filter Filter device, when the oil and air filter needs to be replaced, pull the connecting plate, drive the sliding rod and the sliding block to slide, the sliding spring is deformed, and the connecting plate is rotated at the same time, the limit rod rotates therewith, remove the limit upper block and the intake pipe, put the new oil and air filter into the limit lower block, rotate the connecting plate, loosen the connecting plate, and the sliding spring generates elastic force to break free from the restraint and drive the limit rod to reset. The limit upper block and the intake pipe are fixed on one side of the limit lower block to filter the gas exhausted by the air compressor. At present, most of the exhaust gases of air compressors contain a lot of oil after compression. If the exhausted gas is not effectively filtered, the gas discharged outside the air compressor will pollute the air. However, when it is in use, the filter component cannot be self-cleaned, and oil will accumulate in the pipeline, requiring more frequent cleaning and maintenance, which increases maintenance costs and downtime.
