Patent attributes
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.
