PURPOSE: An integrated bed system for oxygen generator is provided which is capable of optimizing air dispersion and the oxygen-nitrogen separating process by integrally designing a conventional bed separation type bed structure used in small oxygen generators correspondingly to a new valve structure. CONSTITUTION: The integrated bed system for oxygen generator a basic bed(100) comprising two beds and an oxygen tank; and two purging devices for surrounding the basic bed, wherein the basic bed performs functions including inflow of compressed air, nitrogen adsorption, oxygen separation and pressure reduction in the state that the basic bed is covered with front purging device and rear purging device, the front purging device(200) comprises air inlets(201a,201b) into which compressed air is flown from an air compressor installed at the outside; nitrogen outlets(202a,202b) for discharging nitrogen adsorbed from molecular sieve (zeolite) of the basic bed into the outside; and an oxygen outlet(205) for producing oxygen through an oxygen tank by passing through the separation process of first bed or second bed, wherein oxygen passing through the bed of the front purging device passes through oxygen separation ports(301a,301b) flown in the rear purging device so that the oxygen is moved to the oxygen inlets(302a,302b) through oxygen moving passageways, and wherein orifices are fixed to both side of the oxygen inlets to prevent back flow of oxygen.
