PORTABLE AEROSOL FIRE-FIGHTING DEVICE

摘要

The present invention relates to a hand-held aerosol fire suppression apparatus, comprising safety pole (1), button (2), enclosure of cartridge (4), enclosure of cooling layer (6), jet nozzle (8), tapered jet orifice (9), enclosure of apparatus (10), combustion chamber (11), rear fender (14), piezoelectric ceramics (15), rear cap (17) and safety ring (18); wherein the rear cap (17) is screwed to the enclosure of apparatus (10); the jet nozzle (8) is screwed or fitted to the enclosure of apparatus (10); a chemical agent (5) is installed in the enclosure of cartridge (4) and a cooling material (7) is installed in the enclosure of cooling layer (6) in the enclosure of apparatus (10); a thermal insulating layer (3) is installed between the enclosure of apparatus (10) and the enclosure of cartridge (4), between the enclosure of apparatus (10) and the enclosure of cooling layer (6), and between the rear fender (14) and the chemical agent (5); the combustion chamber (11) is installed between the enclosure of cartridge (4) and the enclosure of cooling layer (6); a groove (12) is arranged on the enclosure of apparatus (10) to facilitate gripping. Compared to that in the prior art, the apparatus in the present invention has the following advantages: the safety ring and button can ensure safety of the apparatus; the cooling layer and thermal insulating layer can eliminate flames and cool down the apparatus to protect the operator against scalding; the tapered jet orifice and jet nozzle can greatly increase the jet length and jet velocity, and thereby improve the fire suppression efficacy.
