Abstract

The invention relates to an electrically-started chlorate oxygen candle grain, and belongs to the technical field of oxygen generators. The chlorate oxygen candle grain comprises an oxygen-producing explosive block, an ignition charge column, igniters and inorganic cotton, wherein more than two grooves matched with starting charge columns in size are formed in the top of the oxygen-producing explosive block, the starting charge columns are located in the grooves, mounting holes are formed in the ignition charge column, the igniters are placed in the mounting holes, and the igniters are connected in series or in parallel through wires, wherein the igniter and the ignition powder column are fixed through inorganic cotton. In the oxygen candle grain with the structure, heat generated after the igniter is electrified can decompose the ignition grain and generate heat, so that the oxygen generating explosive block is ignited, and smooth starting of an oxygen candle is realized.

Description

technical field [0001] The invention relates to an electrically activated chlorate oxygen candle, belonging to the technical field of solid chemical oxygen generators. Background technique [0002] The solid chemical oxygen generator utilizes the thermal decomposition reaction of chlorate to provide oxygen, and the combustion of its oxygen-producing medicine block is similar to the combustion of a candle, so it is also called "oxygen candle". Chlorate oxygen candles have the advantages of normal pressure safety and reliability, no environmental restrictions, maintenance-free, long life, small size, light weight, simple operation, and convenient transportation. Therefore, it is widely used as an emergency oxygen supply device in aerospace, high-altitude skydiving, ships and submarines, plateau hypoxia, mine danger avoidance, and toxic and harmful places such as petroleum and chemical industry. [0003] The start-up of chlorate oxygen candles is directly related to the safe c...
