Description
Technical field
The present invention relates to the field of molecular-sieve oxygen generator, particularly relate to a kind of molecular-sieve oxygen generator and oxygen container thereof.
Background technique
Oxygen is to keep the indispensable material of human life, however some in particular cases people have to perhaps need the oxygen of higher concentration in the face of lacking the environment of oxygen, based on this demand, oxygen generating plant is used and is given birth to.
People generally are divided into two classes to the demand of oxygen: be used for correcting the pathologic anoxic, that treats disease is called oxygen therapy with oxygen, and the urgent oxygen therapy that wherein is used for the rescue urgent patient is called again first aid oxygen therapy; Be used for to correct the physiological anoxic, with build up health, prevent disease and improve working and learning efficient etc. be referred to as the oxygen health care with oxygen.
Oxygen therapy mainly adopts oxygen technique to have three kinds with oxygen and oxygen oxygen for health care: chemical-agent technique, Deep Cooling Method, pressure swing adsorption method.Wherein the omnibus control system subtraction unit is simple, little investment, and cost is low, and automaticity is high, and is easy to operate, flexibly and can reach fast and use the oxygen requirement, the small-sized molecular-sieve oxygen generator that is convenient for carrying of more suitable making.
Pressure swing adsorption starts from 20th century the fifties, and the idea of oxygen separation and nitrogen derives from Skarstron circulation and the Gerin-Domine circulation of 1958 at first from air.But due to the restriction of zeolite molecular sieve technology at that time, pressure-variable adsorption fails to be applied to air-separating oxygen-making.Until artificial synthetic zeolite's technology in 1970 has had greater advance, pressure swing adsorption method just begins for air-separating oxygen-making.
At PSA(Pressure Swing Adsorption, pressure-variable adsorption) molecular-sieve oxygen generator, be called for short molecular-sieve oxygen generator.Molecular-sieve oxygen generator is in oxygen preparation, in preventing that oxygen in oxygen container is back to molecular sieve tank when the molecular sieve tank decompression exhaust, most of brand molecular-sieve oxygen generators all generally adopt the external independently one-way valve of oxygen container to realize, also have some brand molecular-sieve oxygen generators directly to adopt shutoff valve to realize intercommunication between oxygen container and molecular sieve tank, to reach the purpose of all pressing tonifying Qi in the decompression exhaust tank.
But the pipeline of the structure of the external independent one-way valve of oxygen container of molecular-sieve oxygen generator is more, and cost consumption is larger, is unfavorable for the machine miniaturization; Molecular-sieve oxygen generator directly adopts the structure of shutoff valve very easily to cause the unstable of machine performance.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of oxygen container, and the oxygen container that has solved molecular-sieve oxygen generator in the prior art needs external independent one-way valve or directly adopts the shutoff valve to cause the unsettled defective of machine performance.
for solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of oxygen container is provided, it is used for molecular-sieve oxygen generator, comprise the oxygen container upper cover, the oxygen container body, oxygen container lower cover and pressure regulator valve, described oxygen container body is arranged between oxygen container upper cover and oxygen container lower cover, described pressure regulator valve is arranged on the bottom of oxygen container lower cover, the inboard of described oxygen container upper cover is provided with two inlet holes, the surrounding of described inlet hole forms the pit of arc, the top of described pit is coated with cover plate, also be placed with diaphragm between described cover plate and pit.
