[0002] In order to facilitate the spraying operation of paint, it is often necessary to use a paint spray gun equipment. The utility model patent with patent application number CN202220806499.5 discloses an advertising spray gun. The shielding cover installed on the paint spray gun can shield and protect the paint sprayed from the nozzle to prevent the sprayed paint from rebounding and splashing, thereby contaminating the staff. The motor is started to drive the scraper in the paint pot to rotate. During the rotation, the scraper scrapes the inner wall of the paint pot to scrape off the residual paint on the inner wall of the paint pot, thereby cleaning the paint pot, which can effectively avoid paint waste. According to the technical solution disclosed by the invention, when the existing paint spray gun equipment is used, on the one hand, it is easy to cause the paint to be unable to be continuously transported to the nozzle due to the deflection or flipping of the paint spray gun during the painting operation, which is not conducive to ensuring the uniformity and stability of the paint spraying operation. On the other hand, when there are certain impurities in the paint, it is easy to cause the nozzle to be blocked, which is not conducive to ensuring the safe spraying of the paint.
