Double-fluid atomizing spray gun

The utility model discloses a double-fluid atomizing spray gun which comprises a spray head, a protection pipe, a quick connector and a hexagonal gas-liquid mixer, a first-stage atomizing section is arranged in the hexagonal gas-liquid mixer, a gas inlet is formed in the right end of the hexagonal gas-liquid mixer, a liquid inlet is formed in the upper end of the hexagonal gas-liquid mixer, and the first-stage atomizing section, the gas inlet and the liquid inlet are all connected with the hexagonal gas-liquid mixer. Through the combination of different spray heads, spray with different shapes, different flows and different particle sizes can be generated. The external protection pipe can protect the spray head and the gas-liquid mixing section under severe environments such as high temperature and impact abrasion, compressed air can be added for cooling under the high temperature environment, the vibration generated by gas-liquid mixing of the gas-liquid mixing section can be reducedthrough the shockproof ri
