Description
Technical field
The present invention relates to oxygenerator technical fields, specially a kind of to have the oxygenerator of molecular sieve failure discrimination function and sentence
Other method.
Background technology
Oxygen occupies very heavy as the essential gas of human survival during daily life and medical first aid
The status wanted.Oxygenerator just comes into being, and oxygenerator can be not only used for medical first aid, and the normal oxygen uptake of healthy people can also promote
Blood circulation, keeps brains clear, and dispelling fatigue effectively promotes working efficiency.Oxygenerator is just becoming universal medical family oriented
Leading-edge products, and largely enter family, but the core members molecular sieve of oxygenerator is easy to fail, and causes compressor negative after failure
Load aggravates, and the service life is shortened in increase abrasion, and goes out oxygen amount suddenly poly- decline, cannot provide the user with suitable oxygen.
Currently, medical machine carries out the separating effect of judgement molecular sieve by detecting oxygen concentration, though effect can be reached, so
And its is of high cost, and safeguard complicated, it is difficult to it spreads in Domestic oxygen erator.Traditional Domestic oxygen erator can only oxygen processed, cannot
Effectively show that it goes out the concentration of oxygen, user lacks intuitive impression, also, in the use with oxygenerator, oxygen effect processed
Fruit will necessarily be deteriorated, and user can not know the separating effect of molecular sieve, thus also not know when to replace point with molecular sieve
Sub- tower can influence the oxygen absorben effect of user, or even can shadow if no longer valid molecular sieve is used for a long time to carry out oxygen processed in user
Ring its health.
