１０によってつぶれることなく空気が充填されている。Further, a breathing bag 3 is provided on the outside of the lower part of the hood 1. The breathing bag 3 consists of two layers: an outer bag 4 and an inner bag 4'. At the top of the breathing bag 3 are oxygen generating cans 5, 5 filled with an oxygen generating agent. The back surfaces of the oxygen generating cans 5, 5 are connected to the half mask 2 via exhalation valves 6, 6 (hidden in FIG. 1 and not clearly shown).
The oxygen generating cans 5, 5 each have numerous discharge holes 7,...
7 are drilled in large numbers. The lower part of the half mask 2 is connected to the inside of the cooling tube 9 inside the breathing bag 3 via the intake valve 8. The cooling cylinder 9 has a built-in spring 11 that reaches the bottom inside the breathing bag 3 and has a collar 10 at the bottom.
A neck band 12 is fixed to one side of the hood 1. The free end 13 of the neckband 2 is connected to the opposite side of the hood by fasteners. The breathing bag 3 is filled with air without being crushed by the collar 10 even when not in use.

は８〜４ぞとされる。In the oxygen generating cans 5, 5, high temperature oxygen is generated by the reaction between carbon dioxide gas and water in exhaled breath and the oxygen generating agent. This oxygen and exhaled air are the discharge holes 7 of the oxygen generating cans 5, 5,...
, 7 is discharged from the can, flows down between the inside of the breathing bag 3 and the cooling tube 9, then ascends the cooling tube 9 expanded by the spring 11, passes through the intake valve 8, and enters the half-face mask 2. Reach within. By the time this high temperature gas reaches the intake valve 8, it is cooled down to a temperature at which it is safe to inhale, for example, 4 g or less. There is no particular limit to the internal volume of the breathing bag 3, and it is usually 8 to 4.

難燃性が大きいものほど好ましい。The strength of the spring 11 is, for example, when the inner volume of the breathing bag 3 is 8. When the breathing bag 3 is released from the collapsed state, the outside air is passed through the exhalation valve 6 and the oxygen generating cans 5, 5 into the breathing bag. It is said that the strength is such that when it is attracted within 4, it becomes less than 2 current @. Further, it is preferable that the material of each member has higher heat resistance and/or flame retardancy.

中へ内蔵することもできる。In particular, the inside of the breathing bag 3 is filled with a high oxygen concentration, for example, 40% or more, so there is a risk of ignition and combustion at high temperatures. To prevent this risk, it is preferably heat insulating, heat resistant and flame retardant. Incidentally, the outer bag 4 of the breathing bag shown in FIG. 1 is made of heat-resistant fiber cloth coated with aluminum, and the inner bag 4' is made of a nylon-Surlyn composite film. However, the breathing bag 3 may have one layer as long as it satisfies the above requirements. The lids of the oxygen generating cans 5, 5 are exposed on the outside of the breathing bag 3, making it easy to replace the oxygen generating agent. You can also.

に向って押しつけられている。Inside the oxygen generating can 5, the powdered or granular oxygen generating agent is sandwiched between two mat-like filters to prevent it from moving inside the can and being unevenly distributed, and from the outside toward the center of the can with a restraining spring. Being forced.
