【考案の詳細な説明】
本考案は酸素発生缶に関し、さらに詳細には酸
素自給型マスクの酸素発生缶に関する。[Detailed Description of the Invention] The present invention relates to an oxygen generating can, and more particularly to an oxygen generating can for an oxygen self-contained mask.

であつた。 Breaks through areas where carbon monoxide is generated from fires and explosions in coal mines, mines, etc.
When escaping, conventional methods such as Japanese Industrial Standards are used.
Carbon monoxide self-lifesaving devices (CO masks) based on M76611 have been worn. Although such carbon monoxide self-saving devices are small and convenient to carry, they are powerless against the release of methane gas or oxygen-deficient air, which has been viewed as a cause of recent mine accidents.

剤を使用した酸素自給型マスクが知られている。 On the other hand, when methane gas or oxygen-deficient air escapes and carbon monoxide is generated, an oxygen generating agent such as potassium superoxide (KO 2 ), which generates oxygen through a contact reaction with water and carbon dioxide in exhaled breath, is used. Oxygen self-contained masks using oxygen are known.

すべく研究した結果、本考案に到達した。 Conventionally, as such an oxygen generating can, there is an oxygen generating can using potassium superoxide (KO 2 ) or the like. When this oxygen generating can is stored for a long period of time, oxygen is generated due to the reaction between potassium superoxide and the moisture and carbon dioxide in the air that is inevitably brought into the can during filling with potassium superoxide. As a result, we learned that the pressure inside the can increases abnormally and the can often bursts, and as a result of research to prevent such accidents, we arrived at the present invention.

されてなることを特徴とする酸素発生缶である。 In other words, the present invention provides an oxygen generating can for a self-contained oxygen mask that includes a container body filled with an oxygen generating agent that generates oxygen by reacting with moisture and carbon dioxide in exhaled breath, and an internal pressure during storage of the oxygen generating can. It is a safety valve that opens as it rises, and is a rod-shaped body with an elastic tube attached to a bottomed cylindrical body having a center hole in the vertical direction and an exhaust hole communicating with the center hole in the side wall to cover the exhaust hole. An oxygen generating can comprising a safety valve, the safety valve being disposed on the wall or bottom of the container body.

加してもよい。 The oxygen generating agent stored in the oxygen generating can may be any compound that can generate oxygen when brought into contact with moisture and carbon dioxide in exhaled breath, and is usually, for example, potassium superoxide. Further, if necessary, oxygen generation promoters such as oxides of copper, silver, manganese, etc. may be added to potassium superoxide.

れはなく、また、加工も容易なものでかる。 The safety valve is a so-called check valve type that discharges gas in the oxygen generating can but does not take in outside air, and is rod-shaped and uses an elastic tube such as a rubber tube for the valve portion. In other words, a rod-shaped tube with a vertical center hole and a bottom with an opening at one end is provided with an exhaust hole that communicates with the center hole on the side wall, and an elastic tube having an inner diameter slightly smaller than the outer diameter of the tube is provided on the outside of the tube. A tube is attached to cover the exhaust hole, and the structure is simple, there is no risk of malfunction due to failure, and it is easy to process.

を調節することなどにより可能である。 The rod-shaped safety valve shown in Fig. 1 is a bottomed cylindrical body 2 having a center hole 1 that communicates with the inside of an oxygen generating can. An exhaust hole 3 is provided to communicate with the air. The outer opening of the exhaust hole 3 is covered with a rubber tube 4. When the internal pressure of the oxygen generating can becomes higher than a predetermined pressure, the rubber tube 4 is expanded outward, creating a gap between the inner circumferential surface of the rubber tube 4 and the outer circumferential surface of the cylindrical body 2, and the air is exhausted from this gap. , the internal pressure of the oxygen generating can returns to the predetermined pressure. Instead of a rubber tube, an elastic body such as a tube made of synthetic resin may also be used. The predetermined pressure can be adjusted by selecting the elasticity, wall thickness, etc. of the tube, and by adjusting the length from the exhaust hole to the end of the tube.

A center hole (not shown in FIG. 3) of this rod-shaped safety valve 11 is communicated with the inside of the container body 8 of the oxygen generating can. Further, the container body of the oxygen generating can is filled with an oxygen generating agent. The rod-shaped safety valve can be attached to the oxygen generating can by screwing, or by gluing, welding, or flanging.
