Background

The existing oxygen candles (solid chemical oxygen generators) cannot be started to generate oxygen in water no matter the existing oxygen candles are used on an airplane, used in mines or used in submarines, the fact that the existing oxygen candles cannot generate oxygen means that oxygen cannot be supplied to a user cannot be used underwater, because the starting mode of the oxygen candles is that the striking pieces are used for igniting the ignition medicine of the oxygen candles to start oxygen candles, but the oxygen candles cannot be normally started to generate oxygen in water no matter the oxygen candles are vertically or transversely struck with a seat frame. Because the striking piece of the switch above the oxygen candle is required to ignite the ignition powder when the oxygen candle is started to produce oxygen, the striking piece of the switch is required to strike the ignition powder, a certain distance space and strength are required to ignite the ignition powder to spray fire to start the oxygen candle to produce oxygen from the internal solid chemical oxygen production, the striking piece of the switch can be immersed in water when the oxygen candle is started in water, the striking piece can be influenced by the resistance and the pressure of water so as to reduce the striking strength, the ignition powder cannot be normally fired, and the ignition powder cannot be normally ignited to produce oxygen from the internal solid chemical oxygen production of the oxygen candle.

The ignition medicine can not enter water, moisture can not be ignited after the ignition medicine enters water, the solid chemical oxygen generator of the oxygen candle can not be driven to produce oxygen, the ignition medicine is fixed on the oxygen candle shell and also needs to be sealed and waterproof, water vapor is prevented from entering the oxygen candle, and the situation that the inflammable oxygen generator in the oxygen candle is wetted and oxygen is not produced is avoided.

Most of the existing life saving devices for underwater oxygen supply use oxygen cylinders for compressing oxygen, so that the life saving device is large in size, heavy in weight, inconvenient to carry and use, and unsafe in risk of collision and explosion at high temperature. Other life-saving devices can be used only by wrapping the oxygen candle or adding a shell, can not directly start oxygen production by the oxygen candle in water, and the problems that the oxygen candle starts oxygen production in water can not be solved due to the fact that the oxygen candle is not provided with a waterproof device and the oxygen candle is directly used underwater are solved.
