Abstract
The utility model discloses a kind of Backpack type from oxygenrespirator, make in the self oxygen system of this closing, expiration and air-breathing will not cause the significant changes of system pressure.Air bag is full upon exhalation heaves, and during air-breathing, air bag shrinks flat collapse.The pressure in system is basically unchanged, is breathed smooth.If without this buffer air bag, we will exhale toward system and can just exhale into energetically very much, breathe gruelling, set up this pressure buffer air bag, critically important to the practicality from oxygenrespirator.
Description
Technical field
The utility model is related to technical field of fire control, and especially a kind of Backpack type is from oxygenrespirator, for escaping in fire
Raw equipment.
Background technology
According to statistics, 80% is there are about in the lethal number of fire above is smoked dead by toxic smog, only less than 20% be by
Directly burn to death.Therefore, how to prevent that it is extremely one of important measures of reduction fire fatality number to be smoked.It is reported that fire chief
Department has required that the place in hotel, hotel, public place of entertainment et al. cluster is equipped with protection from fumes equipment.But, supply in the market
The protection from fumes equipment of above-mentioned unit application, mainly there is two kinds：A kind of exhaled with the filter-type of charcoal absorption filtering out harmful matter
Haustorium；Another is chemical oxygen generation from oxygenrespirator.Use most universal with filter-type respirator.It was verified that this mistake
Filter type respirator can not effectively prevent smoked dead by toxic smoke, and main cause is filter-type respirator Dark smoke billows, toxic smoke mist high
The scene of fire of saturation is spent, the adsorption filtration of finite active charcoal acts on quickly by toxic smoke saturation, just loses and filter out in three a few minutes
The effect of toxic smoke mist.And though also useful superoxides absorbs CO to chemical oxygen respirator2With releasing O2For breathing, but be the failure to by
Reaction characteristicses, carry out gas distribution design, simply one fill superoxides air vesicle, exhale and air-breathing all in this air
In capsule, the CO of exhalation2The reaction zone and superoxides reaction that by slower diffusion, get to bottom release O2, portion
Divide CO2Also have not enough time to be diffused into bottom and be inhaled into lung again.Needed for oxygen supply with breathing, often need to be produced in advance with oxygen candle
Oxygen oxygen supply.So-called oxygen candle be exactly it is a kind of can be used for saving oneself in anaerobic environment use by heating potassium chlorate（KClO3）Or
Sodium chlorate（NaClO3）Produce the device of oxygen.This chemical oxygenrespirator will attach KClO3Or NaClO3Oxygenerator, and
The larger air bag of volume, heavy, not Portable belt, cost and price are higher, not popular with users, it is difficult to promote.
Application No. 2014102880006（Applicant in preceding application）Devising one kind can shunt exhaling with air-breathing,
It was found from 2014102880006 specification contents are applied for, the CO of superoxides and characteristics of contaminated respiratory droplets2, vapor reaction category
In exothermic reaction, and the face mask type carbon mentioned in this application~oxygen crossover autonomous respiration device structure design fails to solve very well instead
The problem that removes of heat is answered, cause people's suction is hot gas, makes us very uncomfortable, also influences its popularization and application.
Application No. 2015101466395（Applicant in preceding application）In disclose a kind of modified face mask type carbon-oxygen
Crossover autonomous respiration device, the respirator is on the basis of the former, to pass through heat-conducting metal pressing plate and several small-caliber metallics
Air chamber is returned again to after reaction heat is radiated, the defect of poor radiation is solved.But found from actual use, in this envelope
Close in system, pneumatype blows up a balloon like that firmly, in ability call-in system, to exert oneself to breathe very much, have a hunch unsmooth breath, then
Devising one, the air bag of harmomegathus and gas phase are linked as pressure buffer device easily.Air bag is full during expiration heaves, air bag during air-breathing
Recover flat, pressure stability in system, breathe smooth.Here it is applying for background of the present utility model.
