Oxygen generator controller

The running controller for oxygen generator includes an adsorption tower with filled adsorbent to adsorb nitrogen from the inflow air and release oxygen; an air pump to pressurize or vacuumize the adsorption tower; a calandria to connect the adsorption tower and the air pump to form flow loop; a sucking side triple valve on the calandria and in the air pump inlet side for selective communication; an exhaust side triple valve on the calandria and in the air pump outlet side for selective communication; a controlling unit to send command to the sucking side triple valve or the exhaust side triple valve for vacuumizing or pressurizing the adsorption tower; and a signal input unit to judge the valve switching for vacuumizing or pressurizing state running.
