An oxygen generator including: a humidifier tank moves up and down according to a horizontal movement of an adjustment knob so that the humidifier tank can be readily detachable, and thus a user can securely and conveniently use the oxygen generator without any water leakage from the humidifier tank during an operation of the oxygen generator. Also, it is possible to reduce noise due to driving of a compressor, noise due to the nitrogen exhaustion, and noise due to driving of a fan portion when the oxygen generator operates, to display purity information about the discharged oxygen, sensed by an oxygen sensor, as a digitalized numerical value on a display portion so that a user may readily recognize a current oxygen purity, and to drive the compressor at a low power consumption based on a discharge flow rate of oxygen and thereby reduce the power consumption.

What is claimed is: 1. An oxygen generator comprising: a body portion comprising: a fan portion which is installed in an upper portion of a separator to absorb the external air wherein the separator separates an inner area of the oxygen generator in a widthwise direction, a compressor which is installed in a lower portion of the separator to generate the high pressure of the compressed air, a valve manifold assembly which is switched on/off according to an oxygen discharge flow rate adjusted by a user to control the supply of the compressed air provided from the compressor, and an absorption tower comprising an adapter which is supplied with the compressed air passing through the valve manifold assembly to generate the high purity of concentrated oxygen and includes a plurality of ports formed on a top portion and a bottom portion outside of a bed housing; a cover portion comprising: a front cover and a rear cover which are disposed on a front and a rear of the body portion respectively, and side covers which are detachably disposed on both a left side and a right side, and on a top of the body portion; a humidifier tank being installed in a mounting portion put in the front cover to humidify the dry concentrated oxygen, generated from the absorption tower, and then supply the humidified concentrated oxygen, and comprising a cam adjuster wherein the cam adjuster is coupled with an adjustment knob moving in the widthwise direction so that the humidifier tank is fixed on a top of the mounting portion when the humidifier tank moves up, and moves from the top to a lower portion of the mounting portion and thereby is readily withdrawn; a display portion being installed in a front top portion of the body portion to display a purity state of oxygen that the user is currently inhaling, a discharge flow rate thereof, and a malfunction for the user's recognition; a switch portion comprising: a first switch which is installed adjacent to the display portion to switch on/off the oxygen generator, and a second switch which selectively adjusts an oxygen discharge flow rate; and a control portion receiving a signal according to a manipulation of the switch portion to control an amount of air supplied from the compressor to the absorption tower and a number of revolutions of the compressor, and control unstable oxygen when the unstable oxygen is generated from the oxygen generator. 2. The oxygen generator as claimed in claim 1, wherein the separator of the body portion comprises: a first separator of which one end is spaced apart from a front of the body portion and extended towards a lower portion of the body portion, and of which another end is vertically curved and extended to a rear of the body portion, and including a first passing hole formed on a front end so that the absorbed air via the fan portion is moved to a location of the compressor; a second separator being spaced apart from a lower portion of the first separator to be parallel therewith, and including a second passing hole formed on a rear end; and a partition wall dividing the inner area by a similar area ratio along a lengthwise direction of the inner area in an exhaustion chamber to discharge the air to an exhaustion grill wherein the exhaustion chamber is formed between a lower portion of the second separator and a bottom board, and the exhaustion grill is formed on the bottom of the body portion. 3. The oxygen generator as claimed in claim 2, wherein a noise blocking panel or sound-absorbing materials are provided on a top and a bottom of each of the first and the second separators to block and absorb noise occurring from within the oxygen generator. 4. The oxygen generator as claimed in claim 2, wherein the partition wall of the body portion comprises: a first partition wall of which one end is extended from a center of the widthwise direction of the exhaustion chamber along the lengthwise direction thereof and is externally curved; and a second partition wall being installed in a path where the external air flown via the second passing hole is discharged to the exhaustion grill via the first partition wall, and of which one is fixed in the lengthwise direction of the exhaustion chamber to be horizontally extended and of which another end is spaced apart from the first partition wall. 5. The oxygen generator as claimed in claim 2, wherein the compressor of the body portion comprises: a damping portion comprising: a damping rubber being installed to be spaced apart from another damping rubber on the second separator and absorb various vibrations and shocks wherein the various vibrations and shocks are transmitted to the compressor via the bottom of the oxygen generator; and a spring of which one end is fixed to the bottom of the compressor and of which another end is connected to the top of the damping rubber. 6. The oxygen generator as claimed in claim 1, wherein the front cover of the cover portion comprises: a guide facing another guide in an inner top portion of the mounting portion to stably receive the humidifier tank when the humidifier tank is mounted to the mounting portion. 7. The oxygen generator as claimed in claim 1, wherein: the humidifier tank comprises: a cover being formed with a guide piece on a top of a humidifier cup, which is protruded from each of both left and right sides of a cover body to guide an oxygen discharge outlet, formed in the front of the cover body, to face the front of the oxygen generator wherein the water fills the inside of a humidifier cup and the cover body is coupled with a humidifier cup using screws, and a combining bracket being fixed to the upper portion of the mounting portion of the front cover and being connected to a tube line into which the concentrated oxygen generated from the absorption tower is input; the cam adjuster disposed in the lower portion of the humidifier tank comprises: a receiving portion being inserted from the rear of the mounting portion and including a protrusion upwardly protruded on the center of a receiving groove, and an adjustment cam including an insertion groove which is formed on the bottom of a cam body to receive the protrusion of the receiving portion, and a spiral combining groove which is formed along the upper portion of an outer circumferential surface of the cam body from a lower portion thereof; and the adjustment knob comprises: an insertion piece being protruded from an inner circumferential surface of an adjustment ring so that the adjustment cam is inserted into the insertion piece wherein the adjustment ring is extended from a handle of the adjustment knob, and a fixing portion being coupled with the adjustment knob, coupled with the adjustment cam, on the adjustment knob, and thereby being fixed on the receiving portion, and including a guide groove to receive a lower end of the humidifier cup. 8. The oxygen generator as claimed in claim 7, wherein an auxiliary groove is formed in the insertion groove of the adjustment cam to be coupled with the plurality of ribs formed on the protrusion. 9. The oxygen generator as claimed in claim 7, wherein a plurality of ribs is formed on the outer circumferential surface of the protrusion of the receiving portion. 10.
