Micron-sized liquid atomization gun

The invention discloses a micron-sized liquid atomization gun. The liquid atomization gun comprises a gun body and a nozzle and further comprises a bubble generation chamber which is connected with one end of the gun body. A liquid conveying passage and a gas conveying passage mutually separated are arranged in the gun body and are connected with a liquid input port and a gas input portion respectively. A gas-liquid distributor is fixed at one end in the bubble generation chamber close to the gun body, a liquid distribution chamber and gas distribution holes mutually separated are formed in the gas-liquid distributor, and connection holes are formed in the liquid distribution chamber. The output end of the liquid conveying passage is in sealing connection with the liquid distribution chamber and communicated with the bubble generation chamber through the liquid distribution chamber and the connection holes successively, the output end of the gas conveying passage is in sealing connection with the gas distribu
