Disclosed is an air purification device with oxygen-supplying function, in which air in an automobile is sucked by a vacuum pump (2) and purified by a dust collector or an adsorbent such as activated carbon and zeolite, and oxygen is enriched in air to supply oxygen enriched air into the automobile. The air purification device enriches oxygen in air according to a VSA (vacuum swing adsorption) process using a difference between pressure in the adsorption bed (10,11) and atmospheric pressure, in which nitrogen adsorbed into the adsorbent is released using the vacuum pump (2). The air purification device comprises an air filter (1) for removing impurities from air sucked from an inside of the automobile by the vacuum pump (2), an adsorbent for adsorbing nitrogen from air passing through the air filter (1) and passing oxygen, an oxygen tank (16,17) for storing oxygen supplied from the adsorbent and releasing oxygen using a vacuum, and if necessary, an anion generator (18) or a scent generator (19). |
