1. What is the principle of the on-board oxygen concentrator
The on-board oxygen concentrator uses physical methods to produce oxygen, and converts the on-board oxygen by switching the inverter power supply. The 12V/24V DC power supply is converted into the 220V AC power supply required for the working power supply of the oxygen generator, thus constituting the overall technical design of the vehicle-mounted oxygen generator. As a modern means of transportation, the functions of automobiles are becoming more and more advanced. However, so far, there is no functional configuration of on-board oxygen generators. The structure of the utility model includes two major components, a switching inverter power supply and a pressure swing adsorption oxygen-generating device, and two molecular sieve adsorption towers in the oxygen-generating device are the main devices. The circuit of the oxygen generator is connected with the automobile circuit by switching the inverter power supply. Under the series drive of the automatic control circuit, the air compressor compresses the air into the molecular sieve adsorption tower, and the 5A molecular sieve in the tower compresses the air under a certain pressure. The oxygen contained in it is enriched, so as to realize the function of on-board oxygen production.
2. Product features of vehicle-mounted oxygen concentrator
1. Under rated flow: oxygen concentration ≥90% of the vehicle oxygen generators that meet the medical oxygen standard.
2. Only 10A current is needed: 12VDC power supply can produce oxygen up to 3L/min (power consumption per liter 40W), and 24VDC power supply can produce oxygen up to 5L/min (power consumption 48W per liter).
3. The rotary gas distribution valve controls the multi-column pressure swing adsorption oxygen production technology, which has a longer service life and more reliable performance than the solenoid valve control.
4. When the car is idling or driving, it can continuously provide fresh oxygen.
5. DC slotless, brushless, oil-free air compressor. Directly use the vehicle’s own DC power supply (DC12V or DC24V) without using a power converter or other power supply, reducing energy loss and making the product more energy-efficient.
6. The advanced integration technology integrates the functions that the traditional 2-column type needs hundreds of parts to realize into one component, which reduces the failure points and greatly improves the reliability of the machine.
7. Compared with the 2-column pressure swing adsorption, the adsorption pressure is reduced, the load of the compressor is reduced, and the service life of the compressor is prolonged.
8. The AC-DC dual-purpose model can be used both indoors and in cars, which is more convenient and practical.
