Abstract

The invention discloses an automatic injection dry powder fire extinguisher, which comprises a columnar, hollow metal shell, and an injection port is opened on the top of the metal shell; It is filled with an ABC fire extinguishing dry powder layer; a latex film is separated between the expansion agent layer and the ABC fire extinguishing dry powder layer; the edge of the latex film is adhered to the inner wall of the metal shell; the injection port is covered with metal foil. The expansion agent layer may be composed of raw materials that generate expansion gas when heated in the prior art. After a fire occurs, the expansion agent layer produces a large amount of expansion gas, which makes the latex film expand until it explodes, and finally the powder of the ABC fire extinguishing dry powder layer is sprayed out to cover the flame to realize fire extinguishing.
