The embodiment of the invention discloses a low-temperature fire extinguishing agent spraying device, a fire extinguishing device and a fire-fighting unmanned aerial vehicle of the fire extinguishing device. The low-temperature fire extinguishing agent spraying device comprises a liquid air tank, a dry powder tank, a mixer and a spraying pipe which are connected. By arranging the liquid air tank, the dry powder tank and the mixer, liquid air and a dry powder fire extinguishing agent are fully mixed, then the high-pressure low-temperature fire extinguishing agent is formed, the low-temperature fire extinguishing agent is driven to be sprayed out through high pressure generated by vaporization of the liquid air, spraying power is high, and the fire extinguishing effect is good; and meanwhile, by arranging the telescopic and/or angle-adjustable injection pipe, the fire extinguishing performance of the fire-fighting unmanned aerial vehicle is effectively improved, and the high-altitude fire extinguishing requirement is met.

    本申请实施例公开一种低温灭火剂喷射装置、灭火装置及其消防无人机,所述低温灭火剂喷射装置包括相连接的液态空气罐、干粉罐、混合器及喷射管。本申请通过设置液态空气罐、干粉罐及混合器,实现对液态空气与干粉灭火剂的充分混合,进而形成高压低温灭火剂,利用液态空气汽化产生的高压驱使低温灭火剂喷射出,喷射动力强,灭火效果佳;同时,通过设置可伸缩及/或角度可调节的喷射管,有效提升消防无人机的灭火性能,满足高空灭火需求。
