The invention provides a vehicle-mounted oxygen supply device, a vehicle and a control method of the vehicle-mounted oxygen supply device, and belongs to the technical field of automobile accessories. The vehicle-mounted oxygen supply device comprises a control unit, an oxygen concentration sensor, an oxygen generation unit, a CO2 transmission pipeline, an O2 transmission pipeline and a breathing mask, the oxygen generation unit comprises a material chamber, a reaction chamber and a reaction control device located between the material chamber and the reaction chamber, and Na2O2 is contained in the material chamber. The control unit controls the reaction control device to adjust the communication opening degree between the material chamber and the reaction chamber according to the oxygen concentration in the vehicle, when the oxygen concentration in the vehicle is low, the material chamber and the reaction chamber are communicated through the reaction control device, CO2 and Na2O2 react to generate O2, and the lower the oxygen concentration is, the larger the communication opening degree is. Therefore, O2 can be generated in the reaction chamber when the oxygen concentration is low, and Na2O2 is not consumed when the oxygen concentration is high. In addition, Na2O2 is solid, is easy to store in the oxygen generation unit, and occupies a small volume.
本公开提供了一种车载供氧装置、车辆和车载供氧装置的控制方法,属于汽车配件技术领域。车载供氧装置包括控制单元、氧浓度传感器、制氧单元、CO2传输管路、O2传输管路和呼吸面罩,制氧单元包括物料室、反应室和位于物料室、反应室之间的反应控制装置,物料室中装有Na2O2。控制单元根据车内氧气浓度控制反应控制装置调节物料室和反应室之间的连通开度,当车内氧气浓度较低时,反应控制装置连通物料室和反应室,使CO2和Na2O2反应生成O2,且氧气浓度越低连通开度越大。这样既能保证氧气浓度低时反应室内能生成O2,也能保证氧气浓度高时不消耗Na2O2。此外,Na2O2为固体,易储存在制氧单元中,且占用的体积较小。
