FIELD: fire-fighting equipment.SUBSTANCE: invention relates to the field of gas fire-fighting technique and refers to a portable aerosol fire extinguishing device. The original manual aerosol fire extinguishing device comprises an insulating layer (3), an inner sleeve (4), an aerosol generating reagent (5), a heat insulating material (6), a jet nozzle (9), a tapered outlet (10), a housing (11), a head (12) of ignition and a piezoelectric-crystal unit (13). The heat insulating layer (3) is located between the inner sleeve (4) and the aerosol generating reagent (5). The jet nozzle (9) is screwed to the housing (11) by means of thread which contains from 3 to 6 thread segments. Compared to the prior technique level the segmented head structure by which the spray head is pivotally connected to the housing reduces greatly the time of disassembly of the spray head to prevent the possibility of an accident.EFFECT: method enables to improve safety significantly.6 cl, 5 dwg |
