Abstract

The invention relates to the technical field of fire extinguishers, and discloses a pressure storage type portable air foam fire extinguisher which comprises a pressing rod, a grip and a pressure tank. A rotating shaft is movably riveted to the joint of the pressing rod and the grip, the shaft wall of the rotating shaft is in cup joint with a torsion spring, one end of the torsion spring is fixedly connected to the inner side wall of the pressing rod, and the other end of the torsion spring is fixedly connected to the inner side wall of the grip. A first inserting rod is fixedly connected to the side wall of the lower end of the pressing rod, a first groove is formed in the upper end face of the pressing rod, a sliding rod is fixedly connected into the first groove, a sliding block is slidably connected to the rod wall of the sliding rod, and a rectangular hole is formed below the first groove. The lower end face of the sliding block is fixedly connected with a limiting rod, and the limiting rod is slidably connected to the side wall of the rectangular hole. The fire extinguisher can be kept in a vertical state all the time, the situation that the fire extinguisher cannot be used due to inclination is avoided, and more labor is saved during use.

Description

technical field [0001] The invention relates to the technical field of fire extinguishers, in particular to a pressure-storage portable air foam fire extinguisher. Background technique [0002] The air foam fire extinguisher is a new type of fire extinguisher with excellent performance. It can be filled with protein foam, fluoroprotein foam, light water foam and alcohol-resistant foam according to different needs, and it can be used to extinguish the initial fire of various oils and polar solvents. Due to the low density of the foam, it can cover the surface of the flammable liquid. On the one hand, it can take the temperature of the liquid surface and cool the liquid surface. On the other hand, after the liquid is completely covered by the foam, an insulating layer is formed to isolate the air from the liquid. Surface contact, so that the fire is extinguished. [0003] In the prior art, the popularity of fire extinguishers is getting higher and higher. However, few people...
