Background
At present, in a fire-fighting spraying device for extinguishing fire by taking water mist, water mist or foam as a fire extinguishing agent, a high-pressure water pump or an axial flow fan is mostly adopted as a power source, but the two devices have certain defects in practical application. Specifically, the high-pressure water pump can mainly realize long-distance solution injection or foam injection, and if water mist is adopted as a fire extinguishing agent, the injection distance can be relatively short, so that long-distance fire can not be acted on; the turbofan gun using the axial flow fan can solve the problem of conveying and spraying fine water mist, and can improve the fire extinguishing capability of the fine water mist to a certain extent, but the turbofan gun has the defect of higher requirements on the working performance of the axial flow fan, namely, large air quantity and high air speed, and is limited by the prior motor technology in the field, and the motor capable of meeting the requirements generally has the problems of higher manufacturing cost, larger volume and incapability of flexibly rotating.
Therefore, the existing fire-fighting spraying device cannot comprehensively realize the good spraying effect on water mist, fine water mist or foam extinguishing agent.

The larger the diameter of the gas pipeline is, the pressure is correspondingly reduced under the same gas flow rate; therefore, by arranging the high-pressure gas zone and the acceleration zone corresponding to the thin two end parts of the air cannon and arranging the mixing zone corresponding to the thick middle part of the air cannon, the rapid entry of the high-pressure gas, the acceleration of the injection speed of the fire extinguishing agent and the full mixing of the gas and the liquid can be realized (the middle part of the air cannon is thick, the air pressure at the position is reduced, the situation that the liquid nozzle cannot spray fire fighting liquid due to the high pressure in the air cannon can be avoided after the air pressure is reduced, and the atomization of the gas-liquid mixture is facilitated).
Further, the high-pressure gas mechanism comprises a high-pressure gas tank, the gas transmission end of the high-pressure gas tank is communicated with the gas inlet of the air cannon through a gas transmission pipeline, and the gas transmission pipeline is provided with a control valve. By controlling the valve, it is possible to control whether the high pressure gas enters the air cannon and the rate of entry.
Further, the air inlet end of the high-pressure gas tank is communicated with the air compressor. The high-pressure gas amount in the high-pressure gas tank can be continuously supplemented through the air compressor, so that the acting time of the fire-fighting injection device can be prolonged.
