[0002] With the rapid development of the automobile industry and the improvement of people's living standards, cars have become an indispensable means of transportation in daily life. However, during long-distance driving or special circumstances, drivers and passengers may encounter emergencies such as altitude sickness, motion sickness, and suffocation. At this time, if they can get timely oxygen supplementation, it will greatly improve safety and comfort. To meet this demand, on-board oxygen concentrators came into being. On-board oxygen concentrators can generate fresh oxygen in the car through water electrolysis or other methods, providing timely oxygen supplementation for drivers and passengers. However, existing on-board oxygen concentrators have some shortcomings in design and use.

[0003] In particular, many on-board oxygen concentrators are placed on the handrail box of the vehicle. Although such a design is convenient for drivers and passengers to use, it has obvious safety hazards. Since the vehicle may be bumpy during driving, the oxygen concentrator on the handrail box is easy to tip over due to insufficient stability, which may not only damage the oxygen concentrator itself, but also cause accidental injuries to passengers in the car. Therefore, based on the above shortcomings, a multifunctional on-board oxygen concentrator is now introduced to improve this. Utility Model Content
