The effect of the oxygen production agent is sufficiently utilized. Better guarantee is provided for the self-rescuing action.
Description
Technical field
The utility model relates to a kind of selfrescue equipment, is specifically related to a kind of chemical oxygen self-rescuer.
Background technology
Chemical oxygen self-rescuer is a kind of lifesaving appliance that is used under the coal mine.In the time of accidents such as down-hole generation gas, coal-dust explosion or spontaneous combustion of coal seam, the down-hole oxygen concentration sharply descends, and directly jeopardizes underground work personnel's life security.At this moment, the staff can in time open self-contained chemical oxygen self-rescuer, thereby guarantees eupnea, implements the escape action.Present this isolation type chemical oxygen self-rescuer obtains widespread usage in the down-hole; But this isolation type chemical oxygen self-rescuer structurally still has the some shortcomings part: because the air bleeding valve of self-rescuer is contained on the air bag of storing oxygen; Therefore when the amount of oxygen in the air bag and pressure reached certain numerical value, air bleeding valve can be opened exhaust automatically, and the oxygen in the air bag is sent; So not only cause waste, and shortened the service time of self-rescuer.
The utility model content
The purpose of the utility model is the deficiency that exists to prior art, and a kind of reasonable in design, simple in structure, chemical oxygen self-rescuer that can extend working time is provided.
The technical scheme of the utility model is: a kind of chemical oxygen self-rescuer; Comprise tank body that oxygen generating agent is housed and the living Oxygen Generator that is connected with tank body; It is characterized in that: vertically be provided with oxygen cathete in the tank body, the top of tank body is provided with the breathing catheter that runs through air bag, and oxygen cathete is communicated with the inner chamber of tank body through the filter opening that is arranged on its lower end; The lower end of breathing catheter is connected with the upper end of oxygen cathete, and the upper end of breathing catheter is connected with a mouthful tool through flexible pipe; The air bag of breathing catheter one side is provided with the valve that is connected with breathing catheter; The inboard of valve is provided with the backguy that is used to control its switching; One end of backguy is fixedly connected valve, and the other end of backguy passes breathing catheter and is connected on the air bag of a relative side with valve; Tank body is connected through the concentric joint sleeve that is arranged on the breathing catheter outside with air bag.
Above-mentioned a kind of chemical oxygen self-rescuer is characterized in that: the adjustable length of said backguy.
The utility model compared with prior art has the following advantages:
(1) the utility model is reasonable in design, and is simple in structure, easy to use;
(2) can control the quantity that gets into interior carbon dioxide of tank body and steam, the oxygen generating capacity of control oxygen generating agent makes full use of the effect of oxygen generating agent, and action provides better guarantee in order to save oneself.
Through accompanying drawing and embodiment, the technical scheme of the utility model is done further detailed description below.

The specific embodiment
As shown in Figure 1; The utility model comprises tank body 1 that oxygen generating agent 2 is housed and the living Oxygen Generator 3 that is connected with tank body 1; Vertically be provided with oxygen cathete 5 in the tank body 1, the top of tank body 1 is provided with the breathing catheter 7 that runs through air bag 6, and oxygen cathete 5 is communicated with the inner chamber of tank body 1 through the filter opening 4 that is arranged on its lower end; The lower end of breathing catheter 7 is connected with the upper end of oxygen cathete 5, and the upper end of breathing catheter 7 is connected with a mouthful tool 9 through flexible pipe 8; The air bag 6 of breathing catheter 7 one sides is provided with the valve 10 that is connected with breathing catheter 7; The inboard of valve 10 is provided with the backguy 11 that is used to control its switching; One end of backguy 11 is fixedly connected valve 10, and the other end of backguy 11 passes breathing catheter 7 and is connected on the air bag 6 with valve 10 relative sides; Tank body 1 is connected through the concentric joint sleeve 12 that is arranged on breathing catheter 7 outsides with air bag 6.
The adjustable length of said backguy 11.
When the utility model was started working, because amount of oxygen is few in the air bag 6, air bag 6 all was in relaxed state with backguy 11, and at this moment, 11 pairs of valves 10 of backguy do not produce motive force, and valve 10 is in closed condition.When the utility model continued to be used, carbon dioxide per os tool 9, flexible pipe 8 and the breathing catheter 7 of being breathed out by human body constantly got into tank body 1, and generated oxygen with tank body 1 interior oxygen generating agent 2 generation chemical reactions.The part of the oxygen that generates gets into human body through oxygen cathete 5, breathing catheter 7 and mouthful tool 9; The another part that generates oxygen gets into air bag 6 through joint sleeve 12.Air bag 6 expands under the effect of oxygen pressure gradually, and along with the continuous expansion of air bag 6, it is big that its shape and size become, and when air bag 6 is deformed into to a certain degree, then pulling preestablished the backguy 11 of length, and valve 10 is drawn back in backguy 11 thereupon.At this moment, carbon dioxide and steam that human body is breathed out then can lead to breathing catheter 7, are directly discharged by valve 10, and no longer get in the tank body 1.Along with human body constantly sucks oxygen, when the amount of oxygen in the air bag 6 drops to a certain degree, the shape of air bag 6 and size decreases; Backguy 11 is lax; To valve 10 tractive no longer, valve 10 recovers closed conditions, and the carbon dioxide of at this moment being breathed out by human body and steam are once more through flexible pipe 8 and breathing catheter 7 entering tank bodies 1; With oxygen generating agent 2 in the tank body 1 generation oxygen that reacts, replenish the oxygen reserves in the air bag 6.
In view of above-mentioned operation principle; During the work of the utility model self-rescuer; Not only can not drain oxygen in the air bag 6, and can get into according to how many controls of amount of oxygen in the air bag 6 carbon dioxide that reacts with oxygen generating agent 2 in the tank bodies 1 and the quantity of steam, thus control and reduced the consumption of oxygen generating agent 2 effectively; Prolonged the service time of this self-rescuer, for the action of saving oneself in the accident provides reliable guarantee more.
