6', both third on-off valves 7, 7' and both fourth on-off valves 7, 7' are closed.
By operating both the vacuum pumps 3, 3' with the on-off valves 11, 11' open, the interiors of both adsorption tanks 1, 1' are brought to a vacuum state (approximately 100 Torr), and then both the fourth on-off valves 11, 11' are opened. 11' is left as is (open), and the others are opposite to the above, both first on-off valves 2,
2' and second opening/closing valves 6, 6' are opened, both third opening/closing valves 7, 7' are closed, and one vacuum pump 3' is stopped. Atmospheric air is sucked into the adsorption tank 1 through the valve 3 . This sucked atmospheric nitrogen is adsorbed by the nitrogen adsorbent when passing through the adsorption tank 1, so that it is sent into the oxygen tank 4 in the form of separated oxygen.

ことにより酸素タンク４への酸素の供給が連続的
に行われるものである。 Next, when the nitrogen adsorbent in the adsorption tank 1 becomes saturated, the concentration of oxygen fed into the oxygen tank 4 decreases, and the oxygen sensor detects this. Therefore, the first on-off valve 2 and the second on-off valve 6 are closed, the third on-off valve 7 is opened, the first on-off valve 2' and the second on-off valve are opened, and the third on-off valve 7' is closed. When the pump 3' is operated, atmospheric air is sucked into the adsorption tank 1, and oxygen is separated and sent into the oxygen tank 4 in the same way as above, but during this time, due to the suction action of the vacuum pump 3, The nitrogen adsorbed by the nitrogen adsorbent in the adsorption tank 1 is sucked out and sent into the nitrogen tank 5, where it can be returned to a state where nitrogen can be adsorbed again. Even when the adsorbent reaches a saturated state, oxygen can be continuously supplied to the oxygen tank 4 by switching to the adsorption tank 1 by opening and closing each on-off valve.
なお以上の各開閉バルブの開閉操作は圧力検出
や酸素センサー８による濃度検出に基づいて自動
制御をすることができる。 Note that the opening/closing operations of each of the opening/closing valves described above can be automatically controlled based on pressure detection or concentration detection by the oxygen sensor 8.

In addition to being able to supply oxygen continuously, the suction method does not use high pressure, so there is little power loss.
In addition, it is extremely easy to treat moisture in the atmosphere, and because the pressure is low, there is no separation of moisture, so the nitrogen adsorbent lasts about twice as long as conventional ones, and has excellent effects. .
