Problems solved by technology

[0002] Most of the existing fire extinguishers store the fire extinguishing material in the container. When using it, people need to be close to the fire source. The fire extinguisher is operated to spray the fire extinguishing material from the container to the fire area to extinguish the fire. If the fire is violent, the human body is too close. The invention patent discloses a "hand-throwing dry powder fire extinguishing device", patent No. 88106927.2, which can be thrown to extinguish the fire not too close to the fire; the device is composed of fire ignition parts, engine parts and fire extinguishing parts, and the fire extinguishing powder filled is mainly Sodium bicarbonate, ammonium phosphate; this hand-held fire extinguishing device consumes a large amount of industrial raw materials, the cost is high, and the dry powder that is often dropped covers a small space, which is only suitable for small fires with a small range.

Abstract

The invention relates to a fire extinction bomb, which comprises mixed fire extinction powder, explosive and explosive device, wherein said mixed powder comprises mudstone powder, common salt and adhesive; the explosive is at the center of powder, which comprises common explosive drug and compressed gas; the explosive device comprises blasting cap, blasting fuse and safety clamper; the blasting fuse is connected to explosive drug and compressed gas, to reach outside the package of powder to be sealed by safety clamper and adhesive; the clamper is contacted with the package of powder. The invention uses explosion to drive the fire extinction powder, to cover the fire. Compared with present technique, it has low cost and wide application.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a hand-held fire extinguisher that discharges fire-extinguishing substances through explosion. Background technique [0002] Most of the existing fire extinguishers store the fire extinguishing material in the container. When using it, people need to be close to the fire source. The fire extinguisher is operated to spray the fire extinguishing material from the container to the fire area to extinguish the fire. If the fire is violent, the human body is too close. The invention patent discloses a "hand-throwing dry powder fire extinguishing device", patent No. 88106927.2, which can be thrown to extinguish the fire not too close to the fire; the device is composed of fire ignition parts, engine parts and fire extinguishing parts, and the fire extinguishing powder filled is mainly Sodium bicarbonate, ammonium phosphate; this hand-held fire extinguishing device consumes a lar...
