Description

A kind of comprehensive window Self-saving breather of chemical oxygen of integral type

Technical field

The utility model is related to emergency self-saving device field, specifically a kind of comprehensive window chemical oxygen of integral type is saved oneself breathing Device.

Background technology

Current respirator mainly has positive-pressure type self-rescue apparatus, suction type self-rescue apparatus, filtering type self-saving respirator And Self-saving breather of chemical oxygen.

Positive-pressure type self-rescue apparatus has positive-pressure type oxygen breathing apparatus and positive-pressure air respirator；The disadvantage is that positive-pressure type air Self-rescue apparatus usage time is shorter, usually or so hour；Positive-pressure type oxygen self-rescue apparatus uses closed cycle, inhales It receives agent and will produce a large amount of heat in absorbing carbon dioxide process, cause respiratory pattern uncomfortable, and use cost is relatively high； It is neither very convenient on using and carrying.

Filtering type self-saving respirator has very strong specific aim, protection toxic, harmful the disadvantage is that the opposite limitation of use occasion The type of gas depend on the powder charge agent of canister institute amount and type, when toxic, pernicious gas type is unknown, excessive concentration or It when beyond its protective range, cannot use, and when oxygen concentration is less than 17% in environment, cannot also use；Simultaneously very More filtering type self-saving respirator filter tanks are separated with mask, and storage and carrying are not very convenient.

Self-saving breather of chemical oxygen operation principle is：Steam and carbon dioxide in wearer's exhaled gas and oxygen generating agent （Such as KO2）It chemically reacts, generates oxygen rich gas and back and forth breathe use for wearer；The type respirator is followed using enclosed Ring will produce amount of heat in chemical reaction process, therefore user's respiratory pattern can be caused uncomfortable, and current change It is separated to learn oxygen life saving device mask and reaction unit, is not very convenient in use.

Invention content

In view of above-mentioned comparative analysis, the utility model is intended to provide a kind of comprehensive window Self-saving breather of chemical oxygen of integral type, To solve the problems, such as current respirator use and carry upper inconvenient and existing Self-saving breather of chemical oxygen use it is uncomfortable, O in use in the patent of invention of appeal citation is solved simultaneously₂Concentration can be gradually reduced problem；Accomplishing portable, guarantor Ensure that the self-rescue apparatus reaction box disposably can be used 20 minutes or more while demonstrate,proving safe, filters malicious box and disposably can be used 30 Minute or more.

The purpose of this utility model is reached by following measure, and a kind of comprehensive window chemical oxygen of integral type is saved oneself breathing Device, including：Comprehensive window mask, netted head-shield restraint zone, reaction box and the malicious box of filter.

The utility model mainly utilizes CO₂With oxygen generating agent（Such as KO₂）Reaction generates O₂, formed in respirator reaction box rich Oxygen is after the pipe cooling that cools down for human body respiration；CO₂The a small amount of CO generated from human body respiration₂And the CO inside reaction box₂ The CO of releasing agent₂。

Mask is comprehensive window, and there are four mouths for setting above：One is respirator Emergency use mouth, and three are reaction box Connector；What respirator Emergency use mouth connected is the filter poison box of a filtering type；Reaction box connector one is exhalation vents, two A is air entry, and Emergency use mouth, exhalation vents and air entry are both provided with check valve, and gas can only be from exhalation vents to air entry list To circulation；Netted head-shield restraint zone is linked together by buckling with mask.

Reaction box includes the card slot for placing reaction plate, is connect to cooling pipeline, the air entry with check valve that gas cools down Mouth, exhalation vents interface and CO with check valve and control valve₂Releasing agent resettlement groove；Wherein cooling pipeline is formed by two layers, and one Layer is gas passage, and one layer is equipped with coolant, and cooling pipeline uses arrangement of curves, extends temperature fall time, ensures cooling-down effect.

The utility model has installed the filter poison box of a respirator Emergency use additional, can be during reaction box use because each Kind of reason causes in emergency circumstances to use beyond being damaged not working etc. during the respirator usage time limit or use；It should Emergency use mouth uses filtering type principle, can be needed using different filter poison boxes, by control valve to exhalation according to different Gas, which is controlled, is switched fast self-rescue apparatus offering oxygen way to realize.

The utility model has the beneficial effects that：The respirator can be with the current respirator of effective solution on using and carrying It is inconvenient, user need to only take mask, you can use；And the respirator can be saved oneself with the current chemical oxygen of effective solution Respirator gives the uncomfortable feeling of people in use；Next has installed the filter poison box of an Emergency use additional, can ensure Extend the usage time of respirator while safe；There is the respirator that can be used repeatedly again, it is only necessary to after use more Change reaction box.
