Description

Gas storage pocket type smoke helmet

Technical field the utility model belongs to the lifesaving appliance that uses in the fire, is applicable to that the fire trapped person escapes from smog.

The background technology fire is recurrent disaster, and the smog toxicity that produces during burning is very big, the people in smog the time slightly length will fall in a swoon or death by suffocation.It is reported that the people who dies in an accident is done harm to by smog earlier in fire.Directly for fire does harm to seldom, so smog also is fiendish killer.

The way that overcomes smog is to wear smoke helmet.Though multiple smoke helmet is arranged in the market, all is the filtered air formula mainly, its filtering tank term of validity is 3 years, the price height also takes and changed in 3 years one.The smoke helmet that carries air has only the band compressed air bottle at present, is fire fighter's equipment special, and its price is higher.This two series products all is difficult to as the standing articles for use of taking precautions against natural calamities in public place or family.So in the propaganda material of present many fire disaster escaping knowledge, emphasize that still covering mouth and nose with wet towel prevents smog, as Beijing " in the citizen's disaster prevention emergency handbook of capital is exactly also to have reflected the disappearance of present this series products.

As a rule, the fire trapped person has only a few minutes at time of escaping in smog.As the standing articles for use of taking precautions against natural calamities in public place or family, smoke helmet is as long as the simple and easy product of a few minutes of surviving in smog is just passable, should be effective, simple to operate, volume is little, and is in light weight low with price.

Summary of the invention is for addressing this problem, the gas storage pocket type smoke helmet that the utility model provides, and its overall plan is; On the existing protective face mask in market, connect a gas-storing bag with appendix, contain air in the bag and by appendix to the face shield gas transmission.Its form and the used compressed air bottle of fire fighter similar just changed into bag, changed into atmospheric air, changed into manual air feed by automatic air feed by compressed air by bottle, is the simple and easy product of a few minutes of can only surviving in smog, and the concrete structure of gas-storing bag is as follows;

Gas-storing bag is made up of double-deck airbag, manual gas cell and three switches (adorn air cock, gas transmission switch, add air cock).

Double-deck airbag is approximate by two sizes, air-locked bag film is nested together and constitutes.Inner bag is smaller, is made by plastic sheeting, is stained with three inflatable air sphere films above, and two horizontal one is vertical, and its inside communicates each other.The inflatable life preserver that the similar swimming place of air sphere film is used is double-layer films when not inflating, and the inflation back forms an air sphere.Air sphere size on the inner bag is consistent with inner bag, when its effect is inflation back formation air sphere, also inner bag is strutted and puts into simultaneously air.Outer bag is made by solid, fire-retardant, air-locked thin-film material, is enclosed within the outside of inner bag, forms double-ply bag.Inside and outside bag opening part keeps six passages than neat rear enclosed at sealing part.Under three switch controls, double-deck airbag and manual gas cell, appendix and outside air are communicated.The size of double-deck airbag will be decided as required, and is changeable, do not make unified regulation.

Manual subsidiary gas cell on the used mercurial sphygmomanometer of the similar hospital of gas cell, volume is small and light.

The effect of three switches is its interior passages of control, and switch leaves, and then passage is logical, and switch closes, and then passage closes.Its concrete effect is;

, two passages are arranged, A1 and B1 in the dress air cock (K1).To be manual gas cell communicate with air sphere film on the inner bag A1, and B1 is that inner bag communicates with outside air.Under the situation that three switches all cut out, open the dress air cock during use, inflate with manual gas cell.Gas enters in the air sphere film by A1, can form three air spheres and also simultaneously inner bag be strutted in the several seconds, and outside air also enters inner bag by B1 simultaneously and adorns gas.When air sphere was supportted maximum, dress gas promptly came to an end.Close the dress air cock this moment, and smoke helmet promptly enters dormant state.

Two passages, A2 and B2 are arranged in the gas transmission switch (K2).A2 be manual gas cell with inside and outside bag between interlayer communicate, B2 is that inner bag communicates with appendix.Under the situation that three switches all cut out, open this switch during use, inflate with manual gas cell.Gas enters inside and outside bag interlayer by A2, because of being subjected to placing restrictions on of outer bag, can only oppress inner bag when interlayer expands, and forces the inner bag air to enter appendix by B2 and imports face shield.

Add air cock (K3) and be behind the dress gas or escape midway, use when having ready conditions aerating inadequately again as sense tolerance.Two passages are arranged, A3 and B3 in the K3.A3 is that manual gas cell communicates with inner bag; B3 is that inside and outside sackholder layer communicates with outside air.Under the situation that three switches all cut out, open this switch during use, inflate with manual gas cell.Gas directly enters inner bag by A3 and carries out aerating, and inner bag expands because of gas increases, if in the inside and outside sackholder layer air is arranged this moment, will force in the interlayer air to be discharged outside the bag by B3.

Therefore, the operation of gas storage pocket type smoke helmet is very simple.When the fire trapped person learns that fire takes place,, open the dress air cock immediately and adorn gas with manual gas cell if ambient air is normal.After several seconds dress gas finishes, switch cuts out promptly enter dormant state.Smog is put on face shield temporarily and is opened the gas transmission switch, inflates with manual gas cell again, and the air in the inner bag will be imported face shield by appendix, and the trapped person just can enter in the smog by easy stages, makes escape be able to success.

Gas-storing bag is to be made by thin-film material, and volume is very little when not inflating, and is very light.Manually gas cell and appendix also are small and light, and integral body can overlay in the parcel, accomplish effective, easy to use, volume is little, in light weight and price is low, carry also easily, be suitable as the standing articles for use of taking precautions against natural calamities in family or public place.

Gas storage pocket type smoke helmet can also be used for fields such as gas roof, dustproof, anti-germ in short time.Under special circumstances, the appendix that also can extend, and with two gas-storing bags in the normal air district in turn when the face shield gas transmission, the staff also can be for a long time works in the inspection shaft of toxic gas or cellar environment.

Description of drawings Fig. 1 is the schematic diagram of gas-storing bag, and W is double-deck airbag, and W1 is outer bag, and W2 is an inner bag, and Q is the appendix that leads to face shield, and S is manual gas cell, and T is the air sphere film that invests on the inner bag, air-flow traffic direction when arrow is work.K1 is the dress air cock, and A1 and B1 are two passages wherein.K2 is the gas transmission switch, and A2 and B2 are two passages wherein.K3 adds air cock, and A3 and B3 are two passages wherein.Fig. 2 is the schematic diagram after the inner bag inflation, the wherein same Fig. 1 of legend.

The specific embodiment is in Fig. 1, and gas-storing bag (W) links to each other with face shield by appendix (Q).Gas-storing bag is made up of double-deck airbag (W1 and W2), manual gas cell (S), three switches (K1, K2, K3).Under the situation that three switches all cut out, open dress air cock (K1) earlier and also inflate during use with manual gas cell.Manually the gas of gas cell enters the air sphere film (T) on the inner bag by the passage (A1) in the dress air cock (K1), and inner bag (W2) is strutted, and outside air enters inner bag by passage (B1) simultaneously.When inner bag was supportted maximum, dress gas promptly came to an end, and will adorn and promptly enter dormant state after air cock is closed.Put on face shield temporarily and open gas transmission switch (K2) when smog, inflate with manual gas cell.Manually the gas of gas cell enters the interlayer between outer bag (W1) and the inner bag (W2) by the passage (A2) in the gas transmission switch (K2), and the air of oppressing simultaneously in the inner bag passes through passage (B2), enters appendix (Q) back input face shield.The trapped person just can enter in the smog, makes escape be able to success.

Behind dress gas or escape midway, also can aerating when having ready conditions aerating again as tolerance deficiency in the sense gas-storing bag.Method is under the situation that three switches all cut out, open add air cock (K3) after, inflate with manual gas cell, this gas will directly enter inner bag (W2) by the passage (A3) that adds in the air cock, inner bag expands because of gas increases, if have air in the inside and outside sackholder layer this moment, will force in the interlayer air to be discharged outside the bag by passage (B3).Close after aerating finishes and add air cock, gas-storing bag enters dormant state again.
