Problems solved by technology

[0003] Some existing dry powder extinguishers are not convenient to hold during use, sometimes they will fall, and they are prone to air leakage during storage, which affects the performance of use, and some even cannot spray dry powder
In addition, when violent collisions and high temperatures are encountered, explosions may sometimes occur, which is very unsafe

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a dry powder fire extinguisher. Background technique [0002] Dry powder fire extinguishers are mainly composed of active fire extinguishing components, hydrophobic components, and inert fillers. The fire extinguishing components are the core of dry powder fire extinguishing agents. The substances that can play a role in fire extinguishing mainly include: ammonium phosphate, sodium bicarbonate, sodium chloride, chlorine Potassium etc. The fire extinguishing principle of the dry powder fire extinguisher is: first, the volatile decomposition products of the inorganic salts in the dry powder chemically inhibit and negatively catalyze the free radicals or active groups produced by the fuel during the combustion process, so that the chain reaction of combustion is interrupted and Fire extinguishing; the second is to rely on the powder of dry powder to fall on the surface of combus...
