OXYGEN CONCENTRATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an oxygen concentrating device having a simplified and inexpensively constituted valve control structure and easy in assembling work. SOLUTION: In the oxygen concentrating device 50, complex wiring, expensive control circuit and the like are dispensed with and the control structure of valve is remarkably simplified and the equipment is formed at a low cost, because the switching of oxygen concentrating mode and desorbed gas discharge mode to each other by mode switching valve structures 1-6 is performed by using a driving transformation and transmission structure 17 for mechanically transforming the driving force of a rotation driving part such as a motor to the driving force of valve switching without using an electrical control structure by a solenoid valve group and a sequence control circuit, and the switching timing of the mode is carried out by rotational phase angle control. Fault is also decreased and the maintenance is easily performed. Further the assembling work is simplified because no wiring part is contained.
