The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
This utility model mainly is comprised of liquid oxygen container 16, fire prevention air bag 4, oxygen uptake switch 10 and connecting duct 14.Fire prevention air bag 4 also can design more humane external form as required, and whole device can be designed to shape miscellaneous as required.
The outer wall of the outer wall of liquid oxygen container 16 and connecting duct 14 is adhesively fixed, one end of connecting duct 14 connects fire prevention air bag 4, the other end is provided with oxygen uptake switch 10, liquid oxygen container 16 has the gas outlet 15 that passes into connecting duct 14 with the bond site of connecting duct 14, and by the closure of piston-type switch control gas outlet 15, piston-type switch is by piston 1, piston push rod 3, switch security box 5, safety plate 6 and switch knob 9 consist of, piston 1 places on the orbiting piston 2 in the liquid oxygen container 16 and can seal gas outlet 15,, the outer end of piston 1 connection pushing piston do not drive the piston push rod 3 of piston rotation but moving, safety plate 6 and switch knob 9 are fixed on the piston push rod 3, safety plate 6 places in the switch security box 5 and can slide along the cross track 8 that communicates and 90 degree fan type long rails 7, and switch security box 5 is fixed on the chamber wall Extendible flake 17 of liquid oxygen container 16.
Switch knob 9 is by the position of piston push rod 3 control pistons 1; Leave behind the gas outlet 15 of liquid oxygen container 16 liquid state of liquid oxygen container 16 gasifies immediately and enters connecting duct 14 when piston 1, one end of connecting duct 14 connects fire prevention air bag 4, oxygen after the gasification enters fire prevention air bag 4 and expand into to a certain degree, the other end of connecting duct 14 connects oxygen uptake switch 10, oxygen is arrived when oxygen uptake switch 10 through connecting duct 14 by fire prevention air bag 4, when oxygen uptake switch 10 was opened, oxygen just can provide oxygen by oxygen uptake switch 10.
As shown in Figure 1, oxygen uptake switch 10 and fire prevention air bag 4 are connected to the two ends of connecting duct 14, and the outer side edges of the lateral surface of liquid oxygen container 16 and connecting duct 14 is bonding affixed, and 15 are connected through the gas outlet; Piston 1 just in time is in the position of liquid oxygen container outlet 15, and piston 1 can move to the right of orbiting piston 2 under thrust; The center of switch security box 5, switch knob 9, piston 1 and orbiting piston 2 all point-blank; Switch knob 9, safety plate 6 and piston 1 are fixed on the piston push rod 3, and switch knob 9, piston 1, on a certain position of safety plate 6 betweens and are on the degree of 90 in the switch security box 5 fan type long rails 7 respectively at two; After arriving cross track 8 behind safety plate 6 90-degree rotations, safety plate 6 just can move forward, and switch knob 9 just can move right when also only having safety plate 6 to move right; When rotary switch handle 9, safety plate 6 is and then rotation simultaneously, but piston 1 does not rotate; When pull switch handle 9 moves right, safety plate 6 and piston 1 and then move right simultaneously, thereby piston 1 is pushed away position directly over the liquid oxygen container outlet 15, piston 1 moves to the right of orbiting piston 2, arrives connecting duct 14 by liquid oxygen container outlet 15 after the liquid oxygen gasification in the liquid oxygen container 16.Under the state that this device is not also started working, for conserve space, connecting duct 14 need be pressed on the linkage section of liquid oxygen container 16, so that extrusion space is placed liquid oxygen container 16.
Form under this device busy state: after piston 1 moves to the right of orbiting piston 2, arrive connecting duct 14 and enter fire prevention air bag 4 by liquid oxygen container outlet 15 after the liquid oxygen gasification in the liquid oxygen container 16, fire prevention air bag 4 expand into to a certain degree, is enough to help drowning people's breathe air of raising one's head; Connecting duct 14 has been started working and has been expanded at this moment; Oxygen arrives oxygen uptake switch 10 by fire prevention air bag 4 by connecting duct 14, as long as can obtain oxygen just anoxia person catches in its mouth out oxygen uptake switch 10.
Under the active force of elastic gum 13, two fixed angle sheet 11 the right are tightly to be combined in one to oxygen uptake switch 10 under normal circumstances, and oxygen can't pass through oxygen-absorbing nozzle.
When oxygen uptake, fixed angle sheet 11 left sides can be rotated around fixed axis 12 when externally pressure is greater than elastic gum 13, fixed angle sheet 11 left sides are mutually close, fixed angle sheet 11 the right are then opened at this time, and oxygen just can by oxygen-absorbing nozzle switch arrival oxygen-absorbing nozzle, just can provide oxygen to anoxia person.When the outside recovered not have pressure, under the active force of elastic gum 13, the right of two fixed angle sheets 13 was tightly to be combined in one, and oxygen can't pass through oxygen-absorbing nozzle again.
The utlity model has following advantage:
1) this device can help human body to bubble through the water column, no matter whether the client is able to swim, as long as carrying out very shirtsleeve operation just can realize saving oneself or waiting for rescue, and the pure oxygen of (also can design as required longer time) is breathed can to provide 3-5 minutes, help client's quick flat to become quiet, prevent that persons falling in water from having delayed rescue in flurried situation.
(2) in lacking the environment of oxygen or in the situation of urgent need pure oxygen, occuring unfortunate often is exactly in a few minutes, often also only need a few minutes and flee from the required time of anaerobic environment.This device can provide client 3-5 minutes (also can design as required the longer time) pure oxygen to breathe, provide and flee from the required of short duration oxygen supply of dangerous situation, as long as and carry out very shirtsleeve operation and just can realize.
3) this device is very convenient carries, and minimum can reach 3 cubic centimetres, can be used as ornament or synthesizes on other careless article, as on necklace, mobile phone, belt and the wrist-watch etc., very convenient and practical.
The design considerations of this utility model device:
1, body density and water are very approaching, even slightly low than water, static human body itself just can be kept afloat, but common people can not freely breathe, the people will freely breathe needs the labour contractor to carry away the water surface, will increase to so the displacement that is equivalent to less the same volume of the number of people and help people's new line, the volume of the number of people is about 2L;
2, the liquid oxygen of same quality and gaseous oxygen in the ideal situation volume ratio be 1:800, that is to say that 1 milliliter liquid oxygen gaseous state volume in the ideal situation is 800 milliliters;
3, normal person's pure oxygen breathe one minute about 7 liters, the liquid oxygen that three minutes besoin de respirer is about 27 milliliters, five minutes about 44 milliliters liquid oxygens of besoin de respirer;
4, be about 21 liters oxygen after the gasification of 27 milliliters liquid oxygen, surpass greatly already the volume of the number of people.
