PURPOSE: An oxygen generator is generated which generates high concentrated oxygen by continuously circulating air flown into the apparatus from the outside several times and passing the air through oxygen separation process by adsorption process. CONSTITUTION: The oxygen generator comprises an air pump(10) forcibly circulating the external air by flowing external air into the apparatus; two first and second three-way valves(21,22) which are connected to the air pump in a row so as to selectively control air channels; an oxygen separation device which is connected to each of the first and second three-way valves, performs the process of adsorbing and desorbing nitrogen in the atmosphere, and discharges the separated oxygen after separating oxygen from the external air sent by the air pump; an oxygen storage tank(50) which is connected to the oxygen separation device by the means of a check valve(35) so as to temporarily store oxygen gas separated and discharged from the oxygen separation device; an oxygen discharge device which is connected to the oxygen storage tank by the means of a one-way control valve so as to discharge oxygen into a user; and a two-way control valve which is connected to the one-way control valve as well as the first three-way valve so as to selectively control channels guiding oxygen inside the oxygen storage tank to the first three-way valve through the one-way control valve and channels guiding the flown in air to the first three-way valve by flowing external air into the apparatus, thereby continuously recirculating the oxygen gas stored in the oxygen storage tank, and repeatedly performs the oxygen separation process.
