Using molecular sieve as the adsorption medium, the oxygen and nitrogen in the air are separated, and finally generate high concentration of oxygen.How to use: 1. ON/OFF(1) Plug the power adapter into the power socket(2) Insert the adapter output plug into the power jack of the rear chassis(3) Press the "Power On Switch" button, a white light will appear around the "Power On Switch" button, and the host starts,(4) The LED decorative light on the front of the host lights up, the default function of the host is oxygen mode, and the oxygen outlet starts to release oxygen.(5) The host will automatically stop after 40 minutes of continuous use, press the "Start Switch" button three times to stop the host operation, and press the button again to start the host.2. Oxygen making functionPress the "start switch" button to switch the function key to the oxygen production mode.The default is oxygen mode when power on, the output flow of oxygen mode is 1L, and the oxygen concentration is 35%-55%. This function cannot be used for professional purposes.(1) Insert the oxygen tube plug into the oxygen outlet under the host.(2) Please insert the oxygen tube tightly to the oxygen outlet.(3) Hang the oxygen tube on the head4) Please put the oxygen nozzle in the nose direction, The effect of oxygen delivery is better within 5cm.3. Atomization function:Press the "Start Switch" function key to switch to the fog mode.(1) Use the spray function with the spray can set (atomization kit).(2) Open the lid and add the specified therapeutic medication using an eyedropper or a designated standard container.(3) Connect the connecting tube to the air inlet connection of the atomizing cup.(4) After turning on the power switch, press the start switch to start running the machine, press the start switch again to switch to the fog mode.(5) Press the power switch again to switch to negative ion purification mode.(6) Press the power switch again to implement the shutdown mode, and all indicators are off.4. Method of using oxygen molecular sieve: (1) What is an "oxygen molecular sieve"?The oxygen content in the air is about 20.9%, and the nitrogen content is about 79.1%. The molecular sieve contains ore, which adsorbs nitrogen in the air to separate nitrogen and oxygen, thereby generating high concentration of oxygen.(2) Molecular sieve replacement period.Molecular sieves that separate nitrogen and oxygen from the air have service life and need to be replaced periodically.The life of molecular sieves is affected by the frequency of use and the environment (air temperature, humidity, etc.)After continued use after the service life, the oxygen concentration and flow rate produced will decreaseThe timer built in the main unit manages the use time of the molecular sieve, and the replacement time will be notified in time.When the cumulative use time exceeds the default cumulative use time of 1000 hours or more than a year from the initial use, the red light at the text "EX" above the front of the host will light up. Please replace the molecular sieves as soon as possible..Package List:1 x Host1 x Nasal Inhalation Tube1 x Atomizing Cup1 x Atomization Tube1 x Mouthpiece1 x Accessories1 x Household Power Supply1 x Car Power Supply1 x User ManualNote:Insist on oxygen inhalation for more than 20 minutes every day, the effect is constant and there is no specific time period, you can choose the time you like to use.
