FIELD: fire-fighting facilities.SUBSTANCE: device relates to the field of technique of fire-fighting with gas and relates to a portable aerosol fire extinguishing device Manual aerosol fire extinguishing device comprises a safety contact (1), a button (2), a housing (4) of the cartridge, a casing (6) of the cooling layer, a jet nozzle (8), a tapering outlet (9), a housing (10) of the device, a combustion chamber (11), a rear deflector (14), a piezoelectric ceramics (15), a rear cover (17) and a retaining ring (18). The rear cover (17) is screwed to the housing (10) of the device. The jet nozzle (8) is screwed or attached to the housing (10) of the device. In the housing (4) of the cartridge a chemical agent (5) is placed. In the casing (6) of the cooling layer in the housing (10) of the device the cooling material (7) is placed. Between the housing (10) of the device and the housing (4) of the cartridge, between the housing (10) of the device and the casing (6), and also between the rear deflector (14) and the chemical agent (5) a heat-insulating layer (3) is located. The combustion chamber (11) is located between the housing (4) of the cartridge and the casing (6) of the cooling layer.EFFECT: present invention provides safety of use due to the presence of the retaining ring and a push button, and due to the cooling layer and the heat-insulating layer the possibility is provided of fire extinguishing and simultaneous cooling to prevent burn of the operator.7 cl, 2 dwg |
