Description
Technical field
The present invention relates to chemical oxygen respirator technical fields, it particularly relates to which a kind of positive-pressure type chemical oxygen operation breathes
Device.
Background technique
Chemical oxygen operation respirator can effectively solve present air respirator it is short using the time, typically not greater than 1 hour
Deficiency, while being compared with existing oxygen breathing apparatus, carbon dioxide and the generation of wearer exhalation are absorbed using chemical oxygen generating agent
Oxygen supplies its sucking again, does not use traditional high-pressure oxygen cylinder oxygen supply, avoids high pressure, high-concentration oxygen bring hidden danger,
Also the peace and quiet tank of calcium hydroxide is no longer needed specially to remove the carbon dioxide of characteristics of contaminated respiratory droplets, working service is simple, for emergency
Rescue personnel works under the hazardous environments such as scene of fire, toxic and harmful gas leakage, anoxic using 4 hours；But chemistry at present
Oxygen operation respirator will appear negative pressure in breathing process in mask, some toxic and harmful gas and dust in external environment etc.
Substance can enter in mask sucking human body, bring security risk.
Summary of the invention
For above-mentioned technical problem in the related technology, the present invention proposes a kind of positive-pressure type chemical oxygen operation respirator, energy
Enough overcome the above-mentioned deficiency of the prior art.
To realize the above-mentioned technical purpose, the technical scheme of the present invention is realized as follows:
A kind of positive-pressure type chemical oxygen operation respirator, including completely cut off mask entirely, one end of the full isolation mask connection respiratory siphon,
The other end of the respiratory siphon is separately connected air inlet air bag, cooler II, and the air inlet air bag connects chemical oxygen generator, describedization
It learns oxygen generator and connects cooler I, the cooler I connection outlet air bag, the outlet air bag connects the cooler II, described
Air inlet air bag and outlet air bag are equipped with positive pressure spring mechanism, and the cooler I is connect with the bottom that oxygen is lit up.
Further, the air inlet air bag and outlet air bag total volume are 6-8L.
Further, the air inlet air bag and outlet air bag volume ratio are 1:2-1:4.
Further, alarm device is equipped with outside the air inlet air bag and outlet air bag.
Beneficial effects of the present invention: positive-pressure type chemical oxygen operation respirator of the invention is not increasing high pressure gas cylinder or electrification
In the case of the force(d) (draft) fan in source, by setting inlet, outlet air bag and positive pressure spring mechanism, solving chemical oxygen operation respirator makes
Used time mask is the problem of negative pressure, it is ensured that pressure is consistently greater than 0Pa in respirator mask when wearer use, maintains positive pressure,
The substances such as some toxic and harmful gas and the dust being effectively prevented in external environment enter mask interior suction and enter human body, greatly protect
The breathing life security of emergency management and rescue personnel is hindered.
