2absorb and generate solid K
2cO
2, emit O simultaneously
2, containing the gas of sufficient oxygen, from the porous lid of reative cell, overflow, enter air chamber, then through two the inaccurate check valve suction respiratory apparatus that flow out of accurate inflow.The utility model has overcome mixed-flow respirator, carbon-oxygen exchange reaction lags behind, and need shift to an earlier date oxygen for the drawback of breathing with oxygen candle, can be made into autonomous oxygenrespirator small and exquisite, that conveniently wear, can prevent toxic smog injury, and as the instrument of emergency oxygen supply under anoxia condition.
Description
Technical field
The utility model relates to face mask type carbon-oxygen crossover autonomous respiration device of a kind of expiration and air-breathing shunting, and this respirator is a kind of equipment of escaping for fire, belongs to a kind of of fire-fighting equipment.
Background technology
According to statistics, in the lethal number of fire, approximately have more than 80% smoked deadly by toxic smog, only less than 20%, directly burnt to death.Therefore, how preventing from being smoked is extremely one of important measures that reduce fire fatality number.It is reported that fire chief department has required the place that the crowds such as hotel, hotel, public place of entertainment concentrate to be equipped with protection from fumes equipment.But, for the protection from fumes equipment of above-mentioned unit application, mainly contain two kinds in the market: a kind of is the filter-type respirator of using charcoal absorption filtering out harmful matter; Another kind be chemical oxygen generation from oxygenrespirator.With filter-type respirator, use the most generally.Facts have proved, this filter-type respirator can not prevent by toxic smoke smoked dead effectively, main cause is filter-type respirator Dark smoke billows, the HI SA highly saturated scene of fire of toxic smoke mist, the adsorption filtration effect of limited active carbon is saturated by toxic smoke very soon, just loses the effect of filtering toxic smoke mist in three a few minutes.Though and chemical oxygen respirator also useful superoxides absorb CO
2with emit O
2for breathing, but fail by reaction characteristics, carry out gas distribution design, an air vesicle that fills superoxides just, exhales with air-breathing all in this air vesicle, the CO of exhalation
2will pass through slower diffusion, the reaction zone that could arrive bottom reacts and emits O with superoxides
2, part CO
2also do not have enough time to be diffused into bottom and be inhaled into again lung.For oxygen supply and besoin de respirer, often need to be with the oxygen supply that produces oxygen in advance of oxygen candle.So-called oxygen candle be exactly a kind of be used in anaerobic environment, save oneself use pass through to heat potassium chlorate (KClO
3) or sodium chlorate (NaClO
3) oxygenous device.This chemical oxygenrespirator will attach KClO
3or NaClO
3oxygenerator, volume is larger, heaviness, Portable belt not, cost and price are higher, not popular with users, are difficult to promote.
In view of this, the utility model specialized designs a kind of can expiration and air-breathing shunting, allow breath first react with superoxides, absorbed the CO of exhalation
2, and emit O
2afterwards, then return to air chamber, for air-breathing expiration and face mask type carbon～oxygen crossover autonomous respiration device of air-breathing shunting, the respirator of this new design has overcome the shortcoming of existing simple airbag design, without by oxygen candle oxygen in advance.Device compact and portable, is convenient to make individual Worn type EEBD, and cost is lower, is easy to promote.
Summary of the invention
The utility model object is in order to overcome the deficiency of above-mentioned background technology, and a kind of expiration and air-breathing shunting are provided, and can allow the gas of breathing out be introduced into reative cell, allows superoxides absorb the CO breathing out
2, discharge O simultaneously
2afterwards again for suction novel autonomous respiration device, this novel autonomous respiration device can be guaranteed the CO breathing out
2substantially be absorbed removing, the air of suction has sufficient oxygen.
First the utility model provides a kind of face mask type carbon-oxygen crossover autonomous respiration device, is the face mask type carbon-oxygen crossover autonomous respiration device of expiration with air-breathing shunting,
comprisefollowing parts: be embedded with and filter gauze layer and with the opening face shield of form at opening part; Can allow and exhale and the air chamber of air-breathing shunting; Can absorb CO
