Description
Technical field
The utility model relates to a kind of positive pressure respirator.Specifically, relate to a kind of positive pressure oxygen respirator with automatic tonifying Qi, self-bleeding square breathing storehouse.
Background technology
Oxygen breathing apparatus is the respiratory protection utensil that special industry professional and technical personnel and draegerman must wear in the rescue and relief work process, is mainly used in the place such as mine, fire-fighting, tunnel, subway, petrochemical industry, metallurgy and the nuclear industry etc. that have toxic and harmful and anoxic and provides long breathing and vision protection for the rescue and relief work personnel.Past, traditional oxygen breathing apparatus belonged to negative-pressure type, and user's positive and negative pressure alternating state that invariably accompanies in respiratory infiltrates easily in case seal bad extraneous pernicious gas.Therefore what next week, generally used in a lot of places is positive pressure oxygen respirator, always breathes being higher than under the barotropic state of external atmosphere pressure and carries out, and extraneous pernicious gas can't enter respirator interior, thereby its security reliability is good.There is following deficiency in existing positive pressure oxygen respirator: breathe the storehouse and adopt cylindrical structural more, so breathe storehouse when being related with extraneous parts or equipment at it, owing to be thereby that cylindrical structural makes it be connected comparatively difficulty with extraneous parts, requirement to the space simultaneously is bigger, so structure is not compact; Breathe the storehouse and be connected morely, so be difficult to avoid the leakage of oxygen in the respirator, thereby cause the air pressure of breathing oxygen in the storehouse lower or, make the pernicious gas infiltration easily near atmospheric pressure with the peace and quiet jar of nuts that adopt.
The utility model content
Technical problem to be solved in the utility model is to provide the positive pressure respirator in the square breathing storehouse of a kind of compact conformation, good reliability.
The technical solution of the utility model is as follows: the positive pressure respirator that designs a kind of square breathing storehouse, comprise and breathe storehouse and peace and quiet jar, on described breathing storehouse, be provided with peace and quiet jar that communicates with this breathing storehouse, being provided with spray on this breathing storehouse antetheca gags somebody, junction at described breathing storehouse and peace and quiet jar is provided with screen pack, its main points are: described breathing storehouse is a square structure, in this breathing storehouse, air bag is housed, described air bag rear end is fixed on the rear wall of described breathing storehouse, this air bag front end face bottom and about rolling member all is housed in the portion, this rolling member contacts with the inwall in described breathing storehouse, at least 1 compression spring is housed in the described air bag, this compression spring one end is against on the described air bag antetheca, and the other end is against on the rear wall in described breathing storehouse; At described air bag antetheca air bleeding valve is housed, on the rear wall of described breathing storehouse, is provided with push rod, the centerline collineation of this push rod and described air bleeding valve.
For respirator can well be cooperated with miscellaneous part, save the space of assembling, the utility model will be breathed the storehouse and be designed to square structure, designed and breathed the air bag that the storehouse adapts simultaneously, in order to make air bag unresisted motion in breathing the storehouse, air bag front end face bottom and about rolling member all is housed in the portion so that air bag is can unresisted motion in breathing the storehouse under the effect of gas pressure.At least 1 compression spring is set determines to breathe the gas pressure intensity in storehouse according to the compression spring force.
To breathe storehouse and peace and quiet jar in junction gas leakage in order making, thereby to reduce the air pressure of breathing in the storehouse, described breathing storehouse and peace and quiet jar are one-body molded.
At described air bag front end face top rolling member is housed, this rolling member contacts with the inwall in described breathing storehouse.
Described rolling member is made up of roller bearing and roller, described air bag front end face bottom and about be wholely set rolling sleeve in the portion, described roller is fixed between the described rolling sleeve through roller bearing, this roller contacts with the inwall in described breathing storehouse, so the design roller is little with the contact-making surface of the inwall of breathing the storehouse, thereby frictional force is reduced.
In order to make air bag breathe moving of storehouse inner equilibrium, described compression spring is two, and these two are symmetrically distributed in the described air bag.
Described spray is gaged somebody and is positioned at described breathing storehouse antetheca central authorities, and described air bleeding valve is positioned at described air bag antetheca central authorities, the described spray of this air bleeding valve gag somebody over against.
Beneficial effect: the utility model is designed to square structure by traditional respirator is breathed the storehouse, with the place that contacts in breathing storehouse roller is set at air bag, thus make the utility model compact conformation, greatly reduce production cost; Have be skillfully constructed, simple in structure, implement easily, characteristics such as good reliability.
