DC OXYGEN CONCENTRATOR FOR VEHICLE

摘要

PURPOSE: Provided is a DC oxygen concentrator for vehicles which connects two combination beds in parallel to supply oxygen smoothly when one bed is broken so that it secures safety and trust. CONSTITUTION: In the DC oxygen concentrator for vehicles which inhales air, separates oxygen and supplies it through an oxygen vent, the DC oxygen concentrator comprises the parts of: a pair of oxygen concentration parts which adsorb nitrogen from inhaled air, separates oxygen and concentrates; a main storage tank(40) which stores oxygen supplied from the oxygen concentration part and supplies through the oxygen vent as necessary; a pressure sensor(41) which measures oxygen pressure within the main storage tank; and a main controller(30) which receives from the pressure sensor and controls the oxygen concentration part to supply oxygen when the storage volume of oxygen in the main storage tank is not enough.
