Description

Technical Field

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

[0002] An air compressor is a device used to compress gas. The air compressor is similar in structure to a water pump. Most air compressors are reciprocating pistons, rotary vanes or rotary screws. After the air compressor is used for a period of time, the filtering device is prone to accumulating dust. However, the steps of disassembling the filtering device are relatively cumbersome. Therefore, a filter box is usually provided at the air inlet of the air compressor to preliminarily filter the air entering the air compressor, thereby reducing the possibility of dust entering the air compressor.

[0003] After retrieval, the authorized Chinese patent publication number CN 219472289 U discloses an oil scraping mechanism for an air compressor, which relates to the technical field of air compressors and includes an air collecting hood. An annular clamping groove is formed in the inner wall of the air collecting hood near the top edge. A clamping block is clamped in the annular clamping groove. One side of the clamping block is fixed with a scraping plate. One side of the scraping plate is mutually attached to the inner wall of the air collecting hood. One side of the scraping plate is fixed with a guide plate near the lower part. A groove is formed in the top of the guide plate. In the utility model, a scraping plate is arranged inside the air collecting hood, and one side of the scraping plate is attached to the inner wall of the air collecting hood. Then, through the mutual clamping of the clamping block and the annular clamping groove, the scraping plate can rotate around the inner wall of the air collecting hood, so that when people pull the scraping plate to rotate along the inner wall of the air collecting hood, the oil stains on the inner wall of the air collecting hood can be scraped off. At the same time, the scraped oil stains flow along the scraping plate to the guide plate, and it is convenient for people to collect the scraped oil stains under the guidance of the groove.

[0004] There are still certain deficiencies in the air compressor in the above patent. Although the existing air compressor can filter the oil stains in the air through the set filter screen, there will still be some oil stains that are pressed into the air compressor storage tank along with the air and adhere to the inner wall of the storage tank. Furthermore, when compressing air, the compressed gas is easily contaminated by the oil stains, affecting the normal use of users. Summary of the Utility Model
