【考案の詳細な説明】
火災発生時などに使用される緊急用の酸素発生器として
、最近塩素酸ナトリウムを主剤とする固型の酸素発生剤
を缶体に詰めた酸素発生缶の使用が増えているが、これ
は酸素発生時に缶表面の温度が２００°Ｃ以上になる。[Detailed explanation of the invention] Oxygen generating cans, which are filled with a solid oxygen generating agent containing sodium chlorate as the main ingredient, have recently been increasingly used as emergency oxygen generators used in the event of a fire. However, when oxygen is generated, the temperature of the can surface becomes over 200°C.
この温度を低下させれば、固型酸素発生剤を詰めた酸素
発生缶を組込む緊急用呼吸装置等の構造を簡単にするこ
とができ、かつ使用者が火傷をする心配もなくすことが
できる。If this temperature is lowered, the structure of an emergency breathing apparatus or the like incorporating an oxygen generating can filled with a solid oxygen generating agent can be simplified, and the risk of burns to the user can be eliminated.
本考案は、固型酸素発生剤を詰めた酸等発生缶の表面に
石こう含浸はう帯を加湿して巻き付けた後に、乾燥する
ことにより、上記の問題点を解決しようとするものであ
る。The present invention attempts to solve the above problems by humidifying and wrapping a gypsum-impregnated band around the surface of an acid generating can filled with a solid oxygen generating agent, and then drying the band.

う帯４に含浸されている石こうから結晶水が分離蒸発し
、その時に奪われる気化熱により缶１の表面温度が低下
する。When the temperature of the surface of the can 1 rises while the starter 2 is being operated to generate oxygen, the water of crystallization is separated and evaporated from the gypsum impregnated in the band 4 at the above-mentioned transition temperature. The surface temperature of the can 1 decreases due to the heat of vaporization taken away by the can.

すことができる利点を有する。As mentioned above, the present invention is made by humidifying and wrapping a gypsum-impregnated band around the surface of an oxygen generating can filled with a solid oxygen generating agent based on sodium chlorate. It has the advantage of being able to prevent the temperature of the can surface from rising during use, simplifying the structure of emergency breathing apparatus, etc. that incorporates the oxygen generating can, and eliminating the risk of burns to the user. have
