Description

Technical Field

[0001] The utility model relates to the technical field of spray guns, in particular to a negative pressure thrombus suction and thrombus collection device. Background Art

[0002] Paint, also known as varnish, refers to a viscous liquid that is coated on the surface of an object to be protected or decorated and can form a firmly attached continuous film with the coated object. It is usually based on resin, oil, or emulsion, with or without added pigments, fillers, and corresponding additives, and is prepared with organic solvents or water.

[0003] When latex paint is used for a long time, the wall surface becomes untidy and unsightly due to scratches or graffiti by children at home. In order to beautify the wall, the wall is painted twice. The existing method is to use canned paint to spray the wall that needs to be painted twice.

[0004] The existing canned paint consists of a can body and a nozzle. There is high pressure in the can body. When in use, press the nozzle downward to release the internal high pressure to spray the paint out of the nozzle. This design is easy to use, but can only be operated by hand. When facing higher areas, spraying cannot be carried out and only high-altitude operations can be performed, which is very dangerous. Utility Model Content
