In various toxic, pernicious gases and anaerobic environment, for withdrawing the scene of the accident rapidly, it is compared with the past also have the function of it is light-weight,
Together, fast, impact resistant is opened, the advantages such as reusable, relative cost is low.
But existing isolating compressed oxygen self-lifesaving device, oxygen storage amount is limited, and oxygen supply time is shorter, in wearer's long-time
When can not flee from accident place, it is easy aggrieved because of anoxic.
Utility model content
According to the above-mentioned deficiencies in the prior art, the technical problems to be solved in the utility model is：There is provided one kind can be effective
Increase the isolating compressed oxygen self-lifesaving device of oxygen supply time.
Isolating compressed oxygen self-lifesaving device described in the utility model, including shell, purification pot, compressed oxygen cylinder, exhaust tube,
Air bag and breathing component, wherein spare oxygen generator is additionally provided in shell, the top of shell is equipped with gas commutating valve, gas commutation
The air inlet of valve connects exhaust tube, and a gas outlet of gas commutating valve connects purge pipe, and purge pipe stretches to purification pot
Bottom, the raw oxygen pipeline of another gas outlet connection of gas commutating valve, raw oxygen pipeline stretch to the bottom of spare oxygen generator, spare life
The top communicated air bags of oxygen tank.
The interior lower end of above-mentioned spare oxygen generator is equipped with first partition, and first partition is equipped with several through-holes, raw oxygen pipe
Road extends to the lower section of first partition, and carbon dioxide and water being contacted with oxygen generating agent evenly of characteristics of contaminated respiratory droplets, raw oxygen can be made uniform
It is sufficient.
The interior lower end of above-mentioned purification pot is equipped with second partition, and second partition is equipped with several through-holes, and purge pipe is stretched
To the lower section of second partition, the carbon dioxide of characteristics of contaminated respiratory droplets being contacted with carbon-dioxide absorbent evenly can be made, make titanium dioxide
Carbon removal is more abundant.
Operation principle and process：
In use, compressed oxygen cylinder is cured by oxygen therapy into air bag, then wearer absorbs the oxygen in air bag by breathing component,
The gas of exhalation enters purification pot through exhaust tube, gas commutating valve, purge pipe, its absorbent of the titanium dioxide in purification pot is by gas
Carbon dioxide absorption in body, remaining oxygen enter air bag, are recycled for wearer；When the oxygen in compressed oxygen cylinder not
When sufficient, gas commutating valve is adjusted, the gas in exhaust tube is made to enter spare oxygen generator, the life in spare oxygen generator through raw oxygen pipeline
Oxygen agent is contacted with carbon dioxide and water, generates oxygen, and remaining oxygen enters air bag with newly generated oxygen in gas, is continuously
Wearer supplies oxygen.
Possessed advantageous effect is the utility model compared with prior art：
Isolating compressed oxygen self-lifesaving device described in the utility model can start standby in compressed oxygen cylinder when oxygen deficiency
With oxygen generator, oxygen supply time is increased, guarantee is provided for the escape of wearer.
