The fire extinguishing device is arranged in an electric appliance cabinet, when the temperature in the electric appliance cabinet rises to a certain temperature in case of fire, the thermosensitive wires are self-ignited and detonate aerosol explosive columns through the detonating explosive cartridge, the cooling balls rise, and the steel wire mesh drives the pressure plate to overcome the resistance of colliding balls to rise; the aerosol grain forms a great deal of agglutinate fire-extinguishing aerosol with main components of N2, a small amount of CO2 and metal salt solid particles through self-generated oxidation-reduction reaction, and the fire is automatically and quickly extinguished through the gaps among the cooling balls and the spraying of the steel wire mesh from the spraying holes. The fire extinguishing device for the micro space has the advantages of high fire extinguishing speed, small occupied volume and suitability for being installed in a cabinet.
Preferably, the spray holes are distributed along a plurality of concentric circles; the shape of the spray hole is a stepped hole with a large end positioned at the upper end; the large end of the spray hole is sealed by a sealing film or a sealing plug. The fire extinguishing aerosol can be sprayed out evenly to extinguish fire and prevent dust from entering.
Preferably, a gap is formed between the outer side wall of the aerosol grain and the inner side wall of the cylinder body. Is beneficial to improving the effect of the primary explosive bag to detonate the aerosol grain.
Compared with the prior art, the beneficial effects of the utility model are that: the fire extinguishing device for the micro space has the advantages of high fire extinguishing speed, small occupied volume and suitability for being installed in a cabinet. The spray holes are distributed along a plurality of concentric circles, the large ends of the spray holes are plugged by sealing films or sealing plugs, and the fire extinguishing aerosol is uniformly sprayed out for fire extinguishing and prevents dust from entering. A gap is formed between the outer side wall of the aerosol charge column and the inner side wall of the cylinder body, so that the effect of the primary explosive charge for igniting the aerosol charge column is improved.
