| abstract | The utility model belongs to an oxygen generating device for coal mine underground emergency rescue, and relates to an oxygen candle, which comprises an oxygen candle cylinder body, wherein an oxygen candle starting device is arranged above the oxygen candle cylinder body, and a filtering device is arranged below the oxygen candle cylinder body; an oxygen generating candle body is arranged in the oxygen candle cylinder body and is connected with an oxygen candle starting device; the oxygen candle body is filled with oxygen candle drug which comprises a retardant; a heat insulation material layer is arranged between the outside of the oxygen generation candle body and the inner wall of the oxygen candle cylinder body, a jacket structure is arranged on the inner wall of the oxygen candle cylinder body, and a phase change material is arranged in the jacket structure. By adding the retardant into the oxygen generating candle body, the reaction rate of the oxygen generating candle can be reduced, no side reaction is caused, and the content of harmful gas is reduced; meanwhile, the reaction time of the oxygen generating candle body is prolonged, oxygen is continuously released for people to breathe, and the purpose of emergency rescue is achieved; the jacket structure is arranged on the inner wall of the oxygen candle cylinder body, and the phase-change material is added in the jacket structure, so that the temperature of the shell of the oxygen candle cylinder body is lower than 40 ℃, hands can be in direct contact with the shell, and the oxygen candle cylinder body can be used for heating at a low temperature. |
