[0027] The working principle of this utility model:

[0028] When the nitrogen generator 1 is needed, the air delivery end is first connected to the connecting pipe 2a, so that the air passes through the connecting pipe 2a and first passes through the filter 2c, so that the filter 2c preliminarily filters the dust particles in the air. After passing through the filter 2c, the air passes through the electrostatic filter 2d. The electric field of the electrostatic filter 2d can be adjusted by the manipulator 12. The air filtered by the electrostatic filter 2d enters the interior of the nitrogen generator 1 through the two air inlet pipes 6, so that the nitrogen generator 1 processes the air. The two telescopic columns 503 are moved regularly by the manipulator 12, so that the output ends of the two telescopic columns 503 drive the moving block 502 and the cleaning cloth 501 moves to the left or right so that the cleaning cloth 501 cleans the dust on the top of the electrostatic filter 2d. After the moving block 502 drives the cleaning cloth 501 to move to the right side of the cleaning port 7, the cleaning cloth 501 can be replaced. When it is necessary to take out the filter 2c and the electrostatic filter 2d for replacement, the bolts fixing the connecting plate 404 are removed so that the connecting plate 404 drives the two plug-in blocks 403 to move out from the inside of the frame 2b and the two rotating rods 402. At this time, the two rotating rods 402 can be moved in opposite directions, so that the filter 2c and the electrostatic filter 2d can be pulled out from the inside of the frame 2b.
