A condensation plate 17 is provided below the cooling tank 6. A resistance plate 13 is provided on the left side of the condensation plate 17. A cleaning strip 14, an adjusting screw rod 15 and a first motor 4 are provided below the resistance plate 13.

The cleaning strip 14 is of a semi-circular structure and is integrally hollowed out. The cleaning strip 14 is fixedly connected to the inner wall on the left side of the water vapor separation tank 1. The device can clean the area of the water vapor separation tank 1 by driving the cleaning strip 14 to move by the adjusting screw rod 15 and the first motor 4, thereby improving the reliability of the device and preventing blockage.

[0028] Working principle: When using the anti-moisture structure for a vacuum variable pressure oxygen generator, first connect all the pipelines of the equipment, then start the oxygen generation main unit 5. At the same time, the second motor 7 drives the fan blade 8 to rotate, sucking air from the air inlet 9, taking away heat through the cooling tank 6 to reduce the surface temperature of the condensation plate 17. Then the air enters the water vapor separation tank 1 through the air inlet 10. Under the action of the resistance plate 13, the high-speed air flow is disturbed and settles under the action of gravity. And the small-molecule water vapor will sublime on the surface of the low-temperature condensation plate 17 and drip into the water vapor separation tank 1 and continuously converge. When the water level reaches the position set by the water level sensor 12, the first motor 4 starts to run, driving the cleaning strip 14 to repeatedly scrape the bottom of the water vapor separation tank 1 through the adjusting screw rod 15, removing impurities such as scale on the surface of the water vapor separation tank 1. Then the valves of the first water outlet 2 and the second water outlet 11 are opened to discharge the water containing impurities together, completing the water removal operation.
