<p>A portable aerosol fire-fighting device includes an insurance column (1), a key-press (2), a cartridge housing case (4), a cooling layer shell (6), a nozzle (8), a contractive spout (9), a device housing (10), a combustion chamber (11), a back baffle (14), a piezoelectric ceramic (15), a rear cover (17 and a guard hoop (18). The rear cover (17) is rotating connected with the device housing (10) through a screw thread. The nozzle (8) is screwed or socketed with the device housing (10). The device housing (10) is provided with a powder column (5) set in the cartridge housing case (4) and cooling material (7) set in the cooling layer shell (6). A thermal isolation layer (3) is set between the device housing (10) and the cartridge housing case (4), between the device housing (10) and the cooling layer shell (6), and between the back baffle (14) and the powder column (5). A groove (12) is set on the device housing (10) for hand holding conveniently. It is better than the prior art in that the guard hoop and the key-press can ensure security of the device; the cooling layer and the thermal isolation layer can make the device extinguish the flame and be cooled so as not to scald the operator; the contractive spout and the nozzle can greatly enhance the spraying distance and spraying speed so as to enhance the extinguishing efficiency.</p> |
