answer：It is recommended to consult a doctor to determine the oxygen concentration required by the user、Flow rate and usage time，Airtai oxygen generator is within the specified flow range，The concentration of the new machine is93%。
answer：Molecular screening machine uses air compressor，There must be noise，Mainly judge whether there is abnormal sound。The periodic popping sound in the oxygen generator is the sound of molecular sieve discharging nitrogen is normal.。
answer：According to clinical studies, the direct oxygen supply of molecular sieve oxygen generator is equivalent to other oxygen supply methods.。The medical profession believes that the concentration reaches90%Oxygen meets the medical oxygen standard。The Chinese Pharmacopoeia stipulates that medical oxygen is99.9%，Refers to the use of cryogenic method to produce oxygen（The cryogenic method can only reach the oxygen concentration99%Remove other magazines above）。And now many large hospitals use large molecular sieve oxygen for pipeline centralized oxygen supply。
answer：1、Long oxygen inhalation time；2、Too much water in the humidification bottle；3、The temperature of the water added in the humidification bottle is too high；4、No ventilation around the machine，High temperature；5、Low temperature in autumn and winter，Condensate on the pipe wall Drainage method：After booting，Connect the oxygen tube to the oxygen outlet，Use your fingers to repeatedly open and close the pipe port to drain the water droplets in the pipe。
answer：Ensure the use time according to the doctor's advice under normal pressure，No oxygen poisoning。There are two reasons for oxygen poisoning，One reason is that the oxygen pressure is too high and the carbon dioxide cannot be discharged in time，Causes the accumulation of carbon dioxide in the body and is poisoned。The other is due to the high concentration of inhaled oxygen，The hemoglobin in the blood is oxidized to hyperoxic hemoglobin，Tissue hypoxia caused by the loss of the ability to carry oxygen。
answer：1.Check whether the power plug is properly inserted；2.Check whether the indoor power supply is powered；3.Check whether the fuse is damaged，Replace in time；4.The oxygen generator circuit board is damaged，Please contact after-sales maintenance personnel as soon as possible。
answer：Add pure water to the humidifying bottle、Distilled water or cool boiled，Not suitable for heating water。Higher on the cup Water mark and lower Mark of water mark，Please keep the water volume within the specified range。The water in the humidification bottle is changed once a day。
answer：The cost performance of a household oxygen generator is much higher than that of an oxygen cylinder。The oxygen generator has almost no other expenses except for power consumption，Every job4～6Consume about an hour1KWh，That is0.4yuan。One10LPress the oxygen cylinder with full gas3L/minThe flow can be used continuously6hour，The cost per inflation is50yuan。Secondly，The oxygen generator can work continuously，The oxygen cylinder needs to be filled with oxygen。once again，The oxygen cylinder is a high-pressure container，May explode under high temperature or intense collision，And there is no high-pressure equipment in the oxygen generator，Safe operation。
answer：1.Check whether the flow adjustment is in a non-zero position in the power-on state；2.Check if the oxygen tube is kinked or damaged，Straighten out the oxygen tube or replace the oxygen tube；3.Air leakage at the interface between the humidifying bottle and the machine，Please reconnect；4.Check the intake filter is clogged，Check and clean the air inlet filter or replace with a new high efficiency filter；5.Internal failure of the machine，Please contact after-sales maintenance personnel as soon as possible。
answer：1.Check whether the bottom exhaust port is unblocked；2.Axial fan does not work，Please contact after-sales maintenance personnel as soon as possible。
answer：Remove the humidification bottle from the machine，Clean with neutral detergent and rinse with clean water；Use white vinegar and hot water to1:3Ratio mix，Soak the humidification bottle in the mixture30minute，For disinfection；Rinse the humidification bottle thoroughly with warm water，Dry and set aside。
