Zusammenfassung:	The utility model discloses an air atomization spray gun driven by air. The air atomization spray gun comprises a spray gun body, an ejector pin assembly, an air pressure spring and a nozzle assembly. A gas pipeline and a liquid pipeline are arranged in the spray gun main body, and a cylinder cavity for mounting an ejector pin assembly is arranged in the spray gun main body; the air pressure spring is arranged in the air cylinder cavity, one end of the air pressure spring acts on the ejector pin assembly, and the other end of the air pressure spring acts on the spray gun body. The elastic force of the air pressure spring enables the ejector pin assembly to block a liquid cap of the nozzle assembly. The spray gun body is further provided with an air pressure channel used for driving the ejector pin assembly to overcome the elastic force of the air pressure spring to move so as to open a liquid cap of the nozzle assembly, and the air pressure channel is communicated with the air pipeline.
