Abstract

The invention relates to a liquid air firefighting breather air bottle. The liquid air firefighting breather air bottle comprises an air bottle body; a bottle opening is formed in the bottom end in the air bottle body, and is provided with a combination valve; the combination valve is provided with an exhaust port and a liquid gas injecting port; multiple layers of composite insulation support rods are arranged in the air bottle body; a normal-temperature gas supply pipe, a supercharging gasifying pipe and a comprehensive liquid taking device are arranged in the air bottle body; one end of thesupercharging gasifying pipe communicates with the comprehensive liquid taking device; multiple hook liquid collecting branch pipes are arranged at two ends of the comprehensive liquid taking device;and gravity control automatic liquid taking heads are arranged at the ends, far from the comprehensive liquid taking device, of all the hook liquid collection branch pipes. The comprehensive liquid taking device is arranged in a liner of the air bottle for liquid taking, gasification and gas supply in a full state of liquid in the liner when the air bottle is in any direction; and when the liquidquantity is reduced to a certain extent, gas is directly taken and supplied, so that a breather can normally and continuously supply the gas outwards in any direction.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a gas cylinder of a liquid air fire-fighting respirator and a respirator including the gas cylinder. Background technique [0002] At present, the respiratory protection equipment commonly used by emergency rescuers is mainly positive pressure air respirator and oxygen respirator. It can be used for about 30 minutes, which cannot meet the needs of long-term combat; the oxygen respirator can be used for a long time, but the gas source is high-pressure pure oxygen, the use environment is limited, and the operation is complicated and cumbersome. The starting point of the present invention is to greatly increase the service time of the respirator, so as to meet the long-term combat needs of emergency rescue personnel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas cylinder capable of storing liquid...
