Embodiment 1

[0020] The present embodiment provides a kind of dry powder fire extinguisher that sprays automatically, as figure 1 , including a columnar, hollow metal shell 1, the top of the metal shell 1 has an injection port; the bottom of the metal shell 1 is filled with an expansion agent layer 2, and the space between the expansion agent layer 2 and the injection port is filled with ABC fire extinguishing dry powder Layer 3; a latex film 4 is separated between the expansion agent layer 1 and the ABC fire extinguishing dry powder layer 3; the edge of the latex film 4 is adhered to the inner wall of the metal shell; the injection port is covered with a metal foil 5 (the metal foil is bonded agent adhesion).

[0021] Further the thickness of the latex film increases from the center towards the edges.

[0022] In another preferred embodiment, as figure 2 , a plurality of metal heat conducting fins 11 protrude from the inner wall of the metal shell in the area below the latex film.

Embodiment 2

[0024] This embodiment provides an automatic injection dry powder fire extinguisher, the structure of which is as in Embodiment 1. In particular, the expansion agent layer in this embodiment is made of sodium bicarbonate powder.

Embodiment 3

[0026] This embodiment provides an automatic injection dry powder fire extinguisher, the structure of which is as in Embodiment 1. In particular, the expansion agent layer in this embodiment is made of sodium bicarbonate powder. The expansion agent layer also includes activated carbon powder, copper sulfate pentahydrate powder, citric acid powder, and the mass ratio of activated carbon powder, sodium bicarbonate powder, copper sulfate pentahydrate powder, and citric acid powder is 1:7:6:7.

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.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to an automatic injection dry powder fire extinguisher. Background technique [0002] Existing automatic fire extinguishers generally rely on the precise cooperation of smoke temperature sensors, control circuits, fire pipelines and other structures to realize automatic spraying and fire extinguishing. But the system is complex in structure, easy to damage and high in cost. Therefore, need badly a kind of automatic fire extinguisher with high reliability and simple structure. Contents of the invention [0003] In view of this, the present invention provides an automatic fire extinguisher with high reliability and simple structure. [0004] The object of the present invention is achieved through the following technologies: an automatic injection dry powder fire extinguisher, characterized in that: it comprises a columnar, hollow metal shell, the top of the metal shell is provided with an in...
