Description

A kind of space flight oxygenerator

Technical field

The utility model relates to a kind of oxygenerator, is a kind of oxygen generation efficiency height specifically, and the comfort height uses safe space flight oxygenerator.

Background technology

Oxygen therapy and oxygen health care are to utilize supply oxygen to improve the physiology of human body, biochemical interior environment, promote the benign cycle of metabolic process, to reach treatment disease, relief of symptoms, promotion rehabilitation and prevention pathology, salubrious purpose.Clinical practice proves, oxygen therapy is with the treatment mechanism of its uniqueness, the secondary disease that causes to acute, the chronic ischemia anoxic venereal disease disease of clinical each section with because of anoxic can play effective therapeutic action, medical, oxygenerator for health care be produced as oxygen therapy and the oxygen health care provides convenience.The principle of work of oxygenerator is: utilize molecular sieve physical adsorption and desorption technique, filling molecular sieve in the oxygenerator, nitrogen adsorption in when pressurization can be with air, remaining unabsorbed oxygen is collected, and namely becomes highly purified oxygen through after the purifying treatment.

Oxygenerator mostly adopts molecular sieving nitrogen oxygen, owing to require bigger into and out of tolerance, the inlet, outlet time is short, inlet, outlet equipment and compressor apparatus restricted volume, gas velocity and density are higher when inlet, outlet, easily produce big noise, when user's oxygen therapy or oxygen health care, can't provide quiet, comfortable environment for use.Tradition adopts and pastes the cotton noise that reduces of noise reduction in the oxygenerator, the shortcoming of this method is: interior subsides noise reduction cotton has increased the oxygenerator overall volume, improved production cost, and the noise reduction cotton has heat insulating function simultaneously, be unfavorable for the heat radiation of oxygenerator inner member, influence use properties and life-span.

And at different oxygen therapy requirements, humidity requirement to oxygen also is not quite similar, existing oxygenerator mostly is equipped with the humidifying water tumbler, oxygen is fed supply use after the water humidifying in the humidifying water tumbler, be the washable humidifying water tumblers of 201220022919.7 disclosed a kind of oxygenerator insertion types as the patent No., water tumbler is divided into inlet chamber, outlet chamber and air-chamber, oxygen is sent into water tumbler by inlet chamber, again by emitting abscess bubbling humidification in the water in the air-chamber, oxygen behind the humidification is supplied with by outlet chamber and is used, its weak point is: the water tumbler complex structure, make difficulty, the cost height, disassembly, cleaning inconvenience; Oxygen emits cell size limited by emitting abscess to enter in the water, emits abscess directly to have influence on the oxygen feed speed, has the low excessively problem of oxygen-supplying amount; The oxygen bubbling easily produces noise in the air-chamber, influences oxygenerator environment for use comfort level; In addition, when the water tumbler inner structure was damaged or stop up, the cup internal pressure was excessive, and there is potential safety hazard in effectively pressure release, and work-ing life is short.

When the installation compressor carries out air pressurized in the existing oxygenerator, the existing cushion blocking that uses carries out damping, cushion blocking is intermediate rubber sulfuration, two ends screw-rod structure, is installed on blast inlet or exhaust outlet usually at the oxygenerator inner compressor, and vulcanized rubber is in air intake or the air draft environment for a long time, elastic performance reduces, thereby influence the switching performance between vulcanized rubber and the screw rod, cause cushion blocking to lose efficacy, the compressor vibrations make its mounting structure become flexible, come off, exist and use potential safety hazard, and operating noise is big.

After the existing molecular sieve oxygen generation machine inlet system air inlet, send into molecular sieving nitrogen and oxygen by the compressor pressurizes air, oxygen is sent into the gas-holder oxygen supply, and nitrogen is then discharged oxygenerator.It is directly to be discharged by the base plate air-releasing mechanism that the nitrogen of existing oxygenerator is discharged and since oxygenerator when placing base plate down, when exhaust fast, air-flow easily flows backwards in the oxygenerator, exhaust efficiency is low, and can produce than strong wind and make an uproar; In addition, compressor long term operation heating can't efficiently radiates heat in the oxygenerator finite space, influence the work-ing life of interior other electrical components of compressor and oxygenerator.
