The dust screen can prevent dust impurities from entering the inside of the transmission frame 601.

[0041] Working principle: first, when the filter screen 2 inside the nitrogen making machine main body 1 needs to be cleaned, the control panel of the nitrogen making machine main body 1 starts the lead screw sliding table 501. The lead screw sliding table 501 works to drive the cleaning frame 502 to reciprocate vertically. The vertical movement of the cleaning frame 502 can drive the vibration frame 503 to reciprocate vertically. The vertical reciprocating movement of the vibration frame 503 drives the cleaning plate 504 to move in the same way. The vertical movement of the vibration frame 503 also drives the roller 506 to move vertically. Since the roller 506 is fitted with the corrugated groove of the corrugated rod 507, the vertical movement of the vibration frame 503 will be affected by the roller 506 to move horizontally. The horizontal movement of the vibration frame 503 will drive the cleaning plate 504 to move horizontally under the action of inertia. Since the cleaning plate 504 is fitted with the spring 505, and the other end of the spring 505 is fitted with the inner wall of the vibration frame 503, the movement of the cleaning plate 504 will cause the spring 505 to deform. The spring 505 will recover the deformation to drive the cleaning plate 504 to move, so that the cleaning plate 504 vibrates at a high frequency and a small amplitude. The vertical movement of the high-frequency vibrating cleaning plate 504 cleans the dust on the surface of the filter screen 2, thereby reducing the blocking of the filter screen 2 by dust impurities.

[0042] Secondly, the vertical movement of the cleaning frame 502 also drives the transmission frame 601 to move. The vertical movement of the transmission frame 601 drives the transmission rod 602 to move. The vertical movement of the transmission rod 602 drives the transmission gear 603 to move. Since the transmission gear 603 is connected with the gear rod 604, the vertical movement of the transmission gear 603 will be affected by the gear rod 604 to rotate. The rotation of the transmission gear 603 drives the transmission rod 602 to rotate. The rotation of the transmission rod 602 drives the first bevel gear 605 to rotate. The rotation of the first bevel gear 605 drives the second bevel gear 606 to rotate. The rotation of the second bevel gear 606 drives the large gear 607 to rotate. The rotation of the large gear 607 drives the small gear 609 to rotate. The rotation of the small gear 609 drives the second rotating rod 610 to rotate. The second rotating rod 610 drives the fan blade 611 to rotate. The rotation of the fan blade 611 generates airflow. The airflow is discharged through the air outlet at the bottom of the transmission frame 601. The airflow can push the dust generated during the cleaning process to move downward. The downward movement of the dust enters the collecting frame 4, thereby facilitating subsequent workers to uniformly process.

[0043] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
