The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further description:
The present invention mainly is made up of LOX 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 multi-form shape as required.
The outer wall of the outer wall of LOX 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; LOX container 16 has the air extractor duct 15 that feeds connecting duct 14 with the bond site of connecting duct 14; And by the closure of piston-type switch control air extractor duct 15, piston-type switch is made up of piston 1, piston push rod 3, switch safety box 5, safety plate 6 and switch handle 9, and piston 1 places on the orbiting piston 2 in the LOX container 16 and can seal air extractor duct 15; The outer end of piston 1 connects the piston push rod 3 that can promote that piston moves but not drive piston rotation; Safety plate 6 is fixed on the piston push rod 3 with switch handle 9, and safety plate 6 places in the switch safety box 5 and can slide along cross track that communicates 8 and 90 degree fan type long rails 7, and switch safety box 5 is fixed on the wall of container Extendible flake 17 of LOX container 16.
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 LOX container 16 and connecting duct 14 is bonding affixed, and is connected through air extractor duct 15; Piston 1 just in time is in the position of LOX container outlet 15, and piston 1 can move to the right of orbiting piston 2 under thrust; The center of switch safety box 5, switch handle 9, piston 1 and orbiting piston 2 is in-line all; Switch handle 9, safety plate 6 and piston 1 are fixed on the piston push rod 3, and switch handle 9, piston 1, on a certain position of safety plate 6 betweens and are on the degree of 90 in the switch safety box 5 fan type long rails 7 respectively at two; When safety plate 6 revolve arrive cross track 8 after turning 90 degrees after, safety plate 6 just can move forward, switch handle 9 just can move right when also having only safety plate 6 to move right; When rotor 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 then moves right with piston 1 simultaneously; Thereby push away position directly over the LOX container outlet 15 to piston 1; Piston 1 moves to the right of orbiting piston 2, and the LOX gasification back in the LOX container 16 arrives connecting duct 14 through LOX container outlet 15.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 LOX container 16, so that extrusion space is placed LOX container 16.
Form under this device busy state: after piston 1 moves to the right of orbiting piston 2; LOX gasification back in the LOX container 16 arrives connecting duct 14 and gets into fire prevention air bag 4 through LOX container outlet 15; 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 through connecting duct 14, as long as can obtain oxygen just anoxic person catches in its mouth out oxygen uptake switch 10.
Under the application force of elastic gum 13, two fixed angle sheet 11 the right are tightly to be combined in one under oxygen uptake switch 10 normal circumstancess, and oxygen can't pass through oxygen-absorbing nozzle.
When oxygen uptake; Fixed angle sheet 11 left sides can be rotated around anchor shaft 12 when externally pressure is greater than elastic gum 13; Fixed angle sheet 11 left sides each other near; Fixed angle sheet 11 the right are then opened at this time, and oxygen just can just can provide oxygen to anoxic person through oxygen-absorbing nozzle switch arrival oxygen-absorbing nozzle.When the outside recovered not have pressure, under the application 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 present invention has following advantage:
1) this device can help human body to bubble through the water column; No matter whether the party concerned 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, helps the party concerned to calm down fast, prevents that persons falling in water from having delayed rescue under flurried situation.
(2) in lacking the environment of oxygen or under the situation of urgent need pure oxygen, taking place 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 party concerned 3-5 minutes (also can design the longer time as required) 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 cm3s, can be used as decorative fitting or synthesizes on other careless article, as on necklace, mobile phone, belt and the wrist-watch or the like, very convenient and practical.
The design considerations of apparatus of the present invention:
1, body density and water are very approaching; Even it is slightly low than water; Static human body itself just can be kept afloat, but common people can not freely breathe, and the people will freely breathe needs the labour contractor to carry away the water surface; Will increase to the displacement that is equivalent to the same volume of the number of people less so and help people's new line, the volume of the number of people is about 2L;
2, the LOX of same quality and gaseous oxygen than for 1:800, that is to say that 1 milliliter the gaseous state volume of LOX under perfect condition is 800 milliliters in the perfect condition lower volume;
3, normal person's pure oxygen breathe one minute about 7 liters, the LOX that three minutes besoin de respirer is about 27 milliliters, five minutes about 44 milliliters LOXs of besoin de respirer;
4, be about 21 liters oxygen after the gasification of 27 milliliters LOX, surpass the volume of the number of people already greatly.
