Description
Technical field
The utility model is related to respirator, specially a kind of simple version chemical oxygen breathing for can independently give birth to oxygen when escaping
Device.
Background technology
According to statistics, there are about 80% or more aggrieved personnel smoked by toxic smog in the lethal number of fire when fire occurs
Dead, it is directly burnt to death only less than 20%.It uses currently on the market there are mainly two types of more protection from fumes equipment：It is a kind of
It is the filter-type respirator with activated carbon adsorption filtering out harmful matter；Another kind is chemical oxygen generation from oxygenrespirator.Wherein
Fume respirator it is more universal, but the activated carbon of fume respirator can only to macromolecular gas carry out lattice gear absorption
And be easy to reach saturation state, the effect of filtering poisonous gas is lost soon in scene of fire.And chemical oxygen respirator energy
Enough relatively effective this problems of solution, chemical oxygen respirator are carried out with aqueous vapor with medicament anti-by the carbon dioxide of characteristics of contaminated respiratory droplets
It answers, the oxygen of generation directly feeds human body use, is completely separated with extraneous atmospheric environment.Escape to solve scene of fire
This historic problem is given birth to, many countries have put into a large amount of time with energy in the world, increase the research to breathing equipment,
Filtering type is developed step by step to save oneself breathing equipment, compressed oxygen（Air）Breathing equipment, spontaneous oxygen breathing equipment etc. of saving oneself are a variety of
Breathing equipment.
Filtering type is saved oneself breathing equipment, is acted on by activated carbon or high molecular adsorption filtration, and volume is bigger
MOLECULAR LATTICES is kept off on breathing equipment, and the gas that user can be absorbed into relative harmless is allowed to enter in human body.It is well known that filtering
Formula respirator is also palliative, can not eradicate all pernicious gases in scene of fire and enter human body, and filtering type is exhaled
Haustorium adsorption function is easy for reaching saturation, and usage time is limited.
Compressed oxygen（Air）Breathing equipment can carry out making compressed oxygen according to the environment residing for user currently on the market
（Air）Bottle, the configuration requirement of this covering device is relatively high, carries complicated, compressed oxygen（Air）Bottle is also very heavy, commonly answers now
For fire-fighting operation, do not promoted comprehensively also in the market amateur, manufacturing cost is also high, is not suitable for universal fire
Escape.
Spontaneous oxygen is saved oneself breathing equipment, can be completely cut off with toxic gas environment and be opened, spontaneous relative to filtering type breathing equipment
Oxygen breathing equipment can more have the safety of substantive guarantee user.But spontaneous oxygen breathing equipment currently on the market due to
Structure is all relative complex, wearing mode is not very convenient and the factors such as suction temperature is excessively high, cost is higher make it fail comprehensively
It is promoted.
Utility model content
The purpose of this utility model is to provide the chemical oxygen respirators that can be used for independently giving birth to oxygen when escape, to solve
The problems mentioned above in the background art.
To achieve the above object, the utility model provides the following technical solutions：
A kind of chemical oxygen respirator for can independently give birth to oxygen when escaping, including sequentially connected half face shield, metal medicinal cupping
And air bag, the half face shield are equipped with the headband with velcro, the metal medicinal cupping includes shell and is placed in the shell
The top of the medicine box in portion, the shell is equipped with air inlet, and the bottom of the shell is equipped with gas outlet, and the inner wall of the shell is equipped with
Heat-absorbing material, the medicine box is interior to be equipped with production oxygen material.
As another preferably technical solution, the inner wall of the shell has been plated or coated with the heat-absorbing material to shape
At a heat-sink shell.
Further, a carbon fiber filter screen is equipped in the shell, the carbon fiber filter screen is placed in the bottom of the medicine box.
Preferably, the shell is made of aluminum material.
Further, the bottom of the shell is accommodated in the air bag and the two is seamlessly connected.
The utility model produces oxygen material in metal medicinal cupping can preferentially select KO2Or NaO2,User breathe out two
Carbonoxide, moisture content is reacted with production oxygen material generates oxygen storage in air bag, so as to be used for survivor, the utility model
Outer casing inner wall increases some heat-absorbing materials and can absorb the heat that drug generates during the reaction, to play the role of cooling.
The utility model is at low cost, and easy to use, and one, which encounters toxic gas, dense smoke, coal dust, gas etc., directly to wear, smokelessly
When remove, consequently facilitating marketing.
