Abstract
The utility model discloses a respiratory protective device which is composed of a mask 1 and an air inlet pipe 2, wherein, the mask is provided with an air outlet 3. The air inlet pipe is communicated with a pure air source. A pipeline of the air inlet pipe can be provided with a blower fan 5 and an adjusting valve 6 in order to adjust air input quantity. The utility model can be used for directly respiring pure air and completely isolating powder dust and harmful gas. Thereby, the occurrence of pneumoconiosis can be prevented radically.
Description
The utility model relates to respiratory protection equipment.
In many industrial processes, tend to produce the pernicious gas of dust or trace, and spread in the air.Production operator long-term work under this environment will be suffered from poignant pneumoconiosis, causes the forfeiture of labour capacity, until death.The labour protection measures of being taked at present mainly is exactly to wear anti-dust respirator, by material absorption dust and pernicious gases such as simple isolation or employing active carbons.But because this isolation and suction-operated have limitation and saturation degree, can only reduce the soakage of harmful substance, and can not be isolated fully, therefore, protection is renderd a service very weak.
The purpose of this utility model is to provide a kind of respirator that can completely cut off dust and pernicious gas fully.
The designed structure of the utility model is: respirator is made up of mouth mask and air inlet pipe, and mouth mask is provided with the gas outlet, and an end of air inlet pipe communicates with mouth mask, the other end communicates with the source of the gas of cleaning.
On the basis of said structure, air blast and control valve are set on the pipeline of air inlet pipe; In addition, also can escape pipe will be connected on the gas outlet.
Use the utility model, can directly breathe the air of cleaning and isolated fully dust and pernicious gas, thereby in the generation that fundamentally prevents pneumoconiosis.
Accompanying drawing 1. respiratory organ structure schematic diagrames (there is lid side, gas outlet).
Accompanying drawing 2. respiratory organ structure schematic diagrames (positive, gas outlet uncovered).
Accompanying drawing 3. respiratory organ structure schematic diagrames (positive, gas outlet connects escape pipe).
Mouth mask 1 links to each other with air inlet pipe 2, and an end of air inlet pipe (i.e. outlet) leads to the mouth mask the inside, the other end (being import) and clean source of the gas (as through purified treatment or without the air of pollution) communicate; The position that adapts with user's mouth and nose on mouth mask is provided with gas outlet 3, the lid 4 of outside unlatching can be set on the gas outlet, a side (as: upper side edge) of lid links to each other with mouth mask, and the downside of lid is just outwards opened when the user exhales, and the user when air-breathing lid just close.
Air blast 5 and control valve 6 can also be set on the pipeline of air inlet pipe, so that grow the gas transmission of distance, and can make the breathing consumption of the interior clean gas air inflow of mouth mask greater than the user, like this, just can on the gas outlet of mouth mask, lid be set and what can guarantee still that the user breathes is clean gas.Perhaps on the gas outlet, connect escape pipe 7 (this moment, the position of gas outlet also can be or not the mouth and nose place), the gas that the user breathes out is sent by escape pipe, the environment that the outlet of escape pipe can be in away from the user directly contacts between user and the pollution sources (as dust, pernicious gas) guaranteeing.Control valve is available for users to oneself and regulates suitable air inflow.
Operation principle of the present utility model is: the gas of establishing in the working environment is N
1, air pressure is P
1, the gas of breathing for the user in the mouth mask (and clean gas) is N
2, air pressure is P
2When not establishing air blast in the pipeline, should there be lid the gas outlet, P during expiration
2＞P
1, lid is opened, P when air-breathing
2＜P
1, make cover closing, like this N
1Can not enter in the mouth mask N always that the user breathes
2When in the pipeline air blast being set, escape pipe can not added a cover or connect in the gas outlet on the gas outlet, as long as the suitable air inflow of adjusting makes the N in the mouth mask
2Content is greater than user's breathing consumption, and then the place, gas outlet only has N
2Overflow, and do not have N
1Flow into, that the user breathes equally also is N
2
Mouth mask is good to make the stereo structure that adapts with face, wears by restraint zone 8; The material (as: sponge, fiber etc.) of edge's filling softness of mouth mask can the appropriate comfortable better seal effect of playing again; The gas outlet can be slit or aperture; Air inlet pipe on the mouth mask and escape pipe can only have one or both sides to have, and mouth mask and air inlet pipe, escape pipe all adopt medical plastic or latex to make; If that uses simultaneously is small, can be that a lower-powered air blast and control valve are installed separately on every air inlet pipe, by own gauge tap of each user and air inflow, if in a workshop, use simultaneously for many people, can be a house steward then with the Inlet Manifold Design of leading to clean gas source, unify pressurization by a suitable big air blast of power, draw a plurality of being in charge of to each user then and use separately, control valve then is contained in to be in charge of by user oneself control air inflow; Control valve can adopt knob or fixture type.
