Movable Small Portable Backpack Type Pulse Flow 1-5 Gear PSA Oxygen Concentrator With 93+/-3% Purity From China Factory

Working principle of portable oxygen concentrator

• Oxygen separation principle
  The principle of oxygen separation, as the name suggests, is a technology that uses various methods to separate oxygen in the air. At present, the commonly used technologies in the market include deep freezing, adsorption and so on.
  The portable multi-functional oxygen generator uses the principle of oxygen separation to separate oxygen. Its technology mainly adopts the pressure swing adsorption method. The pressure swing adsorption method uses molecular sieves to separate gases. It mainly uses the physical properties of various gases and gas pressure for desorption.
• Oxygen output principle

The continuous flow of portable oxygen generator is generally less than 1l/min. In order to avoid oxygen loss in the expiratory phase and the end of inspiratory phase, pulse type oxygen delivery mode is generally adopted.

The pulse signal is obtained in the following ways: when the user breathes, a negative pressure signal will appear in the nasal straw, which will be converted into an electrical signal through the pressure sensor, and then the signal at the very early stage of inspiratory phase will be intercepted by the single chip microcomputer. In this way, when the human body is breathing, the valve controlling the oxygen output can always output oxygen at the appropriate time.

• Energy saving principle
  Portable multi-functional oxygen making equipment is portable, so it is often used in outdoor and plateau areas. If there is no power supply in these areas, it is likely to affect the use of the oxygen generator. Therefore, in the design of portable oxygen generator, how to stably output oxygen when there is no electricity is usually considered. The built-in battery and on-board power supply are the common power design of portable oxygen generator. During the design, the use time of the built-in battery should be as long as possible, and the oxygen generator should be charged adaptively according to different power supply equipment.

• Charging and power supply principle
  With the rapid development of portable products, lithium batteries have been widely used. The requirements for power supply of portable oxygen generator are that it can be charged with good power adaptability. At the same time, the charging and power supply management system has the functions of constant current charging current set by external resistance, battery end overvoltage protection, battery temperature monitoring, charging end current set by external resistance, charging state and charging end state indication, overcharge and discharge protection, etc.
