Abstract

A portable atomizing spray fire extinguisher is composed of a fire extinguishing gun, a unit for supplying high pressure to fire-extinguishing chemical, and transmission tubes for fire-extinguishing chemical and compressed air and connected between the said gun and unit. The said gun has a gun body with two channels, a nozzle part and a switch. It features that the fire-extinguishing chemical is atomized and then sprayed out. Its advantages are high fire-extinguishing efficiency, small size, light weight, and low consumption of fire-extinguishing chemical.

Description

Technical field: [0001] The invention belongs to fire-fighting fire extinguishing equipment, in particular to a small and portable fire extinguishing device. Background technique: [0002] Existing fire extinguishing equipment generally adopts long-term continuous spraying of a certain liquid or dry powder fire extinguishing agent to reach the critical value of fire extinguishing to extinguish the fire. This not only needs to consume a large amount of fire extinguishing agent, but the fire extinguishing effect is low; and because a large amount of fire extinguishing agent must be carried, it is inconvenient to move and operate, and cannot flexibly adapt to the fire extinguishing needs of various fire environments; Extensive use will also cause serious pollution to the environment. Invention content: [0003] The object of the present invention is to provide a portable atomized spray fire extinguisher which can save fire extinguishing agent. [0004] Solution of the prese...
