A motor 11 is fixedly arranged on the outside of the U-shaped frame 8, and the power end of the motor 11 movably penetrates the U-shaped frame 8 and is fixedly connected to the rotating rod 9. By arranging two groups of easily replaceable mounting frames 5 and filter plates 6, it is convenient to clean one group of filter plates 6 while filtering through another group of filter plates 6, thereby ensuring the continuous normal operation of the nitrogen generator 2.

[0030] Specifically, a limit block 13 is fixedly provided on the outer side of the tooth plate 12, a slider 14 is fixedly provided on the outer side of the limit block 13, and two sets of slide grooves 15 for docking the slider 14 are opened on the inner side of the U-shaped frame 8.

The filtered air enters the nitrogen generator 2 for nitrogen production. When the filter plate 6 is cleaned, the motor 11 is turned on by an external power supply to drive the rotating rod 9 to rotate. When the rotating rod 9 rotates, it drives the gear 10 to rotate. The rotation of the gear 10 can drive the two sets of tooth plates 12 to move in different directions.

At this time, the filter plate 6 that needs to be cleaned is taken out of the filter box 3, and the new filter plate 6 is installed in the filter box 3 to continue filtering. Then, the movable block 18 is pulled outward through the grip 25. When the movable block 18 moves, it drives the card block 19 to move out of the card slot 20 on the filter plate 6 and stretches the spring 24. Then the filter plate 6 can be pulled out from the inside of the mounting frame 5 for cleaning.
