Abstract:
An air purification device for an automobile with oxygen-supplying function, provided with a suction port and a releasing port for sucking air in the automobile and releasing air into the automobile, and a channel connecting the suction port to the releasing port, comprising:an air filter, adjacent to the suction port, to remove impurities from air; vacuum pump means for sucking air in the automobile; two adsorption beds, connected to the air filter, for separating oxygen from air, said adsorption beds each containing an adsorbent mostly adsorbing nitrogen from air; bypass channel means connecting the adsorption beds to each other, and allowing oxygen enriched air to flow from one adsorption bed to the other adsorption bed; additional pump means for releasing the oxygen enriched air from the adsorption beds; a check valve, connected to each of the adsorption beds and the additional pump means, thus allowing the oxygen enriched air to exclusively flow from the adsorption beds to the additional pump means; and valve means mounted on a channel connected to the two adsorption beds, the vacuum pump means, and the air filter to alternately allow a vacuum and atmospheric pressure to be applied into each adsorption bed, wherein said vacuum pump means is directly seated on the automobile and driven by an engine, each of said adsorption beds converts air sucked from an inside of the automobile into the oxygen enriched air to supply the oxygen enriched air into the automobile by the additional pump means, said air sucked from the inside of the automobile is thus converted into the oxygen enriched air by controlling the channel using the valve means to alternately apply the vacuum and atmospheric pressure into each adsorption bed using vacuum pressure generated from the vacuum pump means according to a vacuum swing adsorption process.
