[0006] This invention has the following beneficial effects: After adopting the above technical solution, this invention not only has high power efficiency and good fire extinguishing performance, but is also portable and lightweight, weighing only 7.3 kg. This invention uses a turbojet engine, which not only produces a large airflow and ultra-high-speed airflow, but also generates water mist, further improving the fire extinguishing effect. The nozzle of the turbojet engine is closer to the fire point, without damaging the fire scene, and can extinguish low- to medium-intensity forest surface fires. The support frame of this invention is a cylindrical support frame, including an upper support frame, a lower support frame, a left support frame, and a right support frame. The upper support frame, lower support frame, left support frame, and right support frame form a cylindrical support frame. The front part of the support frame is fixedly connected to the air guide pipe, and the rear part of the support frame is fixedly connected to the air inlet hood. The turbojet engine is placed in the middle of the support frame, which not only allows the turbojet engine to be installed parallel inside the outer hood, but also ensures stable installation and good jetting effect.
