Technical Field
[0001] The utility model relates to the field of oxygen generators, and particularly relates to a vehicle-mounted membrane oxygen generator. Background Technique
[0002] At present, with the increase in the number of vehicles, self-driving travel has become increasingly popular, especially when traveling to the western plateau. The driver and passengers also have higher requirements for the comfort of the interior space of the vehicle. Currently, the commonly used oxygen supply devices are as follows: 1. Oxygen bags and oxygen cylinders, but the oxygen storage is limited and the usage time is short; 2. Miniature PSA oxygen generators, but the oxygen production capacity is small, only for single-person use, and it cannot meet the oxygen supply in the whole vehicle and generates dust that requires additional filtration.
[0003] Therefore, it is very necessary to invent a vehicle-mounted membrane oxygen generator to solve the above problems. Content of the Utility Model

[0008] Preferably, a plurality of filters are provided, and the plurality of filters are connected in series with each other.
[0009] The technical effects and advantages of the utility model:
[0010] By using a compressor to draw air into it through the air intake and compress it, the compressed air enters the compressed air storage tank, and then enters multiple filters through the compressed air storage tank for filtration. The filtered air is transported to the oxygen generation membrane module. The oxygen generation membrane module separates the oxygen in the air through membrane treatment, and transports the generated oxygen to the oxygen storage tank. If it is necessary to supply oxygen for multiple people in the vehicle, the diffused oxygen supply port is opened. If it is necessary to supply oxygen for single-person nasal inhalation, the nasal inhalation oxygen supply port is opened. The oxygen generation of the present utility model is rapid, and it can be used immediately without waiting. As long as there is power in the vehicle, oxygen will be continuously supplied, without worrying about the problem of oxygen depletion. Moreover, the oxygen purity is sufficient and there is no dust. It can not only supply oxygen diffusedly for multiple people in the vehicle, but also provide single-person nasal inhalation use at the same time. Description of the Drawings
