Description

Technical Field

[0001] The present application relates to the field of spraying machines, and in particular to a motor protective cover and a spraying machine. Background Art

[0002] A sprayer is a special coating equipment that uses spraying technology. The principle is to control the airflow to instantly push the air distribution reversing device to reverse, so that the piston of the pneumatic motor can make a stable and continuous reciprocating motion. The inhaled paint is pressurized and transported to the spray gun of the sprayer through a high-pressure hose. The spray gun instantly atomizes the paint and releases it to the surface of the object to be coated. The sprayer is mainly composed of a feeding device, a spray gun, and an atomization source. However, the existing motor protection cover and sprayer usually use bolts to connect the end cover to the motor body. Special tools must be used for disassembly and installation. Disassembly and installation are cumbersome, which increases labor and reduces practicality. Utility Model Content
