PURPOSE: An air purification device with oxygen-supplying function for vehicles is provided to purify air optimally in a vehicle room by separating air through a dust collector, an absorbent, active carbon, an anion generator and a flavor generator, and to prevent accidents from falling asleep during driving by restring shortage of oxygen. CONSTITUTION: An air purification device comprises an air filter(1) arranged near an intake port to suck air and remove foreign matters from air; a vacuum pump(2) applying suction force to suck air; a vacuum tank(5) connected to the vacuum pump to keep vacuum pressure; adsorbing beds(10,11) having adsorbents adsorbing nitrogen from air by connecting to the vacuum tank and the air filter, and separating oxygen from air; oxygen tanks(16,17) connected to the adsorbing beds, the vacuum pump and the air filter through a valve and an air passage to store oxygen; an oxygen bypass unit placed between adsorbing beds; and a pump discharging oxygen from the oxygen tank. The vacuum pump is installed in the vehicle and driven by an engine. The adsorbing beds generate and supply oxygen indoors by adsorbing and discharging alternately with converting the passage based on vacuum swing adsorption. |
