Summary of the invention
Technical problem to be solved in the utility model provides a kind of emergency escape breathing equipment, wears easily, and oxygen supply is reliable.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of emergency escape breathing equipment comprises head-shield and the oxygen generator that is used for storing living oxidation material that links to each other with described head-shield; Also comprise bladder tank, described bladder tank is provided with gas outlet and air inlet, described bladder tank communicates with described oxygen generator by the gas outlet, and described gas outlet goes out to be provided with the first seal rubber plug, and described the first seal rubber plug is connected with the first draw ring of being located at the bladder tank outside by connecting line; Described head-shield communicates with described bladder tank by air inlet, and described air inlet place is provided with check valve; Be provided with the second seal rubber plug between described oxygen generator and the described head-shield, described the second seal rubber plug is connected with the second draw ring of being located at the head-shield outside by connecting line.Before using the emergency escape breathing equipment, the first seal rubber plug is isolated with bladder tank and oxygen generator, the second seal rubber plug is isolated with oxygen generator and head-shield, thereby so that the living oxidation material in the oxygen generator can because environmental factor goes bad, not guaranteed its reliably oxygen supply when using in the future; When needs use the emergency escape breathing equipment, at first by the first draw ring the first seal rubber plug is pulled out, by the second draw ring the second seal rubber plug is pulled out, oxygen generator can be communicated with bladder tank and head-shield; Then with the head-shield cover to head, steam and carbon dioxide that the people breathes out enter in the bladder tank by air inlet, steam and carbon dioxide in the bladder tank enter in the oxygen generator by the gas outlet, living oxidation material in steam and carbon dioxide and the oxygen generator carries out chemical reaction and produces oxygen, and the people just can absorb these oxygen and keep breathing.Because respiratory system and external environment air are isolated, be not subjected to any toxic gas of fire place generation and the harm of smog during use, be applicable to various toxic and harmfuls and anaerobic environment.
As improvement, described living oxidation material is the alkali metal superoxides.
As improvement, described oxygen generator and described head-shield junction are provided with large clip, guarantee that oxygen generator is reliable with being connected of head-shield.
As improvement, described air inlet and place, gas outlet are provided with little clip.Guarantee oxygen generator and bladder tank, and head-shield is reliable with being connected of bladder tank.
As improvement, described bladder tank is provided with air bleeding valve.
The beneficial effect that the utility model compared with prior art brings is:
The utility model is worn easily, and oxygen supply is reliable; And because respiratory system and external environment air are isolated, be not subjected to any toxic gas of fire place generation and the harm of smog during use, be applicable to various toxic and harmfuls and anaerobic environment.
Description of drawings
Fig. 1 is the utility model half sectional view.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, a kind of emergency escape breathing equipment comprises head-shield 1, the oxygen generator 2 and the bladder tank 3 that are used for storing living oxidation material that link to each other with described head-shield 1.Described bladder tank 3 is provided with gas outlet 7 and air inlet 10, described bladder tank 3 communicates with described oxygen generator 2 by gas outlet 7, and described gas outlet 7 goes out to be provided with the first seal rubber plug 8, and described the first seal rubber plug 8 is connected with the first draw ring 9 of being located at bladder tank 3 outsides by connecting line.Described head-shield 1 communicates with described bladder tank 3 by air inlet 10, and described air inlet 10 places are provided with check valve 11.Described air inlet 10 and 7 places, gas outlet are provided with lesser calorie hoop 6.Guarantee oxygen generator 2 and bladder tank 3, and head-shield 1 is reliable with being connected of bladder tank 3.Be provided with the second seal rubber plug 5 between described oxygen generator 2 and the described head-shield 1, described the second seal rubber plug 5 is connected with the second draw ring 13 of being located at head-shield 1 outside by connecting line.Described oxygen generator 2 is provided with large clip 4 with described head-shield 1 junction, guarantees that oxygen generator 2 is reliable with being connected of head-shield 1.Described bladder tank 3 is provided with air bleeding valve 12, and when the air pressure in the bladder tank 3 was too high, air bleeding valve 12 started, and bladder tank 3 is carried out pressure release.
Before using the emergency escape breathing equipment, the first seal rubber plug 8 is isolated with oxygen generator 2 with bladder tank 3, the second seal rubber plug 5 is isolated with head-shield 1 with oxygen generator 2, thereby so that the living oxidation material in the oxygen generator 2 can because environmental factor goes bad, not guaranteed its reliably oxygen supply when using in the future; When needs use the emergency escape breathing equipment, at first by the first draw ring 9 the first seal rubber plug 8 is pulled out, by the second draw ring 13 the second seal rubber plug 5 is pulled out, oxygen generator 2 can be communicated with bladder tank 3 and head-shield 1; Then head-shield 1 is overlapped to head, steam and carbon dioxide that the people breathes out enter in the bladder tank 3 by air inlet 10, steam and carbon dioxide in the bladder tank 3 enter in the oxygen generator 2 by gas outlet 7, living oxidation material in steam and carbon dioxide and the oxygen generator 2 carries out chemical reaction and produces oxygen, and the people just can absorb these oxygen and keep breathing.Because respiratory system and external environment air are isolated, be not subjected to any toxic gas of fire place generation and the harm of smog during use, be applicable to various toxic and harmfuls and anaerobic environment.
