[0002] A nitrogen generator refers to a device that uses air as raw material and separates oxygen and nitrogen therein by physical methods to obtain nitrogen; the nitrogen generators applied in industry can be divided into three types according to different classification methods, namely cryogenic air separation method, molecular sieve air separation method (PSA) and membrane air separation method. The nitrogen generator is a nitrogen production device designed and manufactured according to the pressure swing adsorption technology.

[0003] According to the Chinese patent with the publication number CN215559022U, an energy-saving and environmental-friendly nitrogen generator is disclosed. By arranging a base, a nitrogen generator, a support frame, a top plate, a glass cover, an air suction fan and an air suction cover, the pollution caused by gas escape and diffusion is greatly reduced, and energy is saved and the environment is protected; the bottom of the base is connected with a fixed shell, a decompression spring and a rubber column, which improves the stability of the bottom of the nitrogen generator.

[0004] Aiming at the above-mentioned disclosed patent content, a filter screen is arranged to filter the air entering the nitrogen generator. After the filter screen is used for a long time, more dust or impurities will adhere to its surface. Therefore, in order to avoid the blockage of the filter screen, the filter screen needs to be disassembled and cleaned every once in a while. Since the filter screen is installed inside the air inlet box, the disassembly process is relatively troublesome, and after cleaning, the filter screen needs to be reinstalled into the air inlet box. This disassembly and cleaning process is time-consuming and laborious, with many operation steps, thus reducing the cleaning efficiency of the filter screen. Content of the Utility Model

[0016] Furthermore, a control panel is installed on the outer surface of the base, and the control panel is electrically connected to the blower and the nitrogen generator respectively.

[0017] By adopting the above technical solution, it is convenient for the staff to start or stop the blower and the nitrogen generator through the control panel.

[0018] Furthermore, one side of the cleaning brush is attached to the filter screen.

[0019] By adopting the above technical solution, when the cleaning brush rotates, it will scrape off the dust or impurities attached to the surface of the filter screen, thereby improving the cleaning efficiency of the filter screen.

[0020] Furthermore, the driving bevel gear meshes with the driven bevel gear, and the diameters of the driving bevel gear and the driven bevel gear are the same.

[0021] By adopting the above technical solution, when the driving bevel gear rotates, it will drive the driven bevel gear to rotate, then drive the movable shaft to rotate, and the movable shaft will drive the cleaning brush to rotate.

[0022] Furthermore, the gear meshes with the rack, and the rack is slidably connected to the chute through a sliding seat.

[0023] By adopting the above technical solution, when the rack moves, it will drive the gear to rotate, and the gear will drive the rotating shaft to rotate, and then drive the driving bevel gear to rotate.

[0024] Furthermore, the sealing plate is adapted to the bottom of the discharge port, and the discharge port is located below the cleaning brush.

[0025] By adopting the above technical solution, the sealing plate can seal the discharge port to prevent gas from being discharged through the discharge port.

[0046] When it is necessary to clean the dust or impurities attached to the filter screen 7, the staff can push the push rod 904. The push rod 904 will then push the rack 902 to move and drive the gear 903 to rotate. The gear 903 drives the rotating shaft 906 to rotate, and then drives the driving bevel gear 908 to rotate. When the driving bevel gear 908 rotates, it drives the driven bevel gear 907 to rotate, and then drives the movable shaft 909 to rotate. The movable shaft 909 will drive the cleaning brush 910 to rotate. When the cleaning brush 910 rotates, it will scrape off the dust or impurities attached to the surface of the filter screen 7 to prevent the dust or impurities from always adhering to the filter screen 7 and causing it to be blocked. Moreover, the cleaned dust or impurities will fall into the interior of the discharge port 912. When it is necessary to clean the dust or impurities in the discharge port 912, the sealing plate 911 can be taken out first so that it no longer blocks the discharge port 912. At this time, the dust or impurities in the discharge port 912 will be discharged. After the impurities or dust are cleaned, the sealing plate 911 can be installed in the discharge port 912 by bolts to seal it.
