AI Technical Summary
In existing nitrogen generators, dust accumulation on the filtration mechanism affects filtration efficiency during nitrogen production, and cleaning also draws away some air, resulting in reduced nitrogen output and decreased production efficiency.
A high-efficiency and energy-saving nitrogen generator was designed. Through the cooperation of a sealing cover and a sealing plate, dust is prevented from flowing into the dust collection box during the cleaning process, ensuring that the air inlet box and the dust collection box are not connected to each other and maintaining good ventilation. A servo motor is used to drive the sealing cover and brush to clean the filter plate, so as to clean the dust at the same time.
Maintaining the air permeability of the filter plate during nitrogen production prevents air loss, increases nitrogen output and production efficiency, and ensures that cleaning the filter plate does not affect the actual amount of air involved in nitrogen production.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1:
[0021] like Figures 1-5As shown, a high-efficiency and energy-saving nitrogen generator includes a base plate 1. Two nitrogen generator bodies 2 are fixedly installed on the top of the base plate 1. A dust collection box 3 is fixedly installed on the top of the base plate 1. An air inlet box 4 is fixedly installed on the top of the dust collection box 3. The nitrogen generator bodies 2 are connected to the interior of the air inlet box 4 through pipes. A filter plate 5 is fixedly installed on the inner wall of the air inlet box 4. A sealing cover 6 is slidably connected to one side of the filter plate 5. A brush 7 is fixedly installed on the inner wall of the sealing cover 6. The open side of the sealing cover 6 is in contact with the filter plate 5. By setting the sealing cover 6, the dust swept by the brush 7 can be prevented from drifting into the air inlet box 4. The inner wall of the sealing cover 6 can rotate. A movable plate 8 is connected, with one side of the movable plate 8 overlapping the notch at the opening of the sealing cover 6, allowing the movable plate 8 to remain horizontal. Dust swept down by the brush 7 falls onto the movable plate 8. A support block 10 is fixedly installed on the inner wall of the air intake box 4, and an abutment rod 11 is fixedly installed on the top of the support block 10. The front end of the abutment rod 11 is movably connected to the bottom of the movable plate 8. When the abutment rod 11 contacts the movable plate 8, it pushes one side of the movable plate 8 upward. Under the action of the lever principle, the movable plate 8 tilts, thereby creating a gap between the sealing cover 6 and the movable plate 8. At this time, dust will flow along the tilted movable plate 8. Plate 8 slides down through the gap. Two sets of limiting cylinders 12 are fixedly installed on the bottom wall of the dust collection box 3. Limiting rods 13 are slidably connected to the inner walls of both sets of limiting cylinders 12. A connecting rod 14 is rotatably connected to the front end of the limiting rod 13. A sealing plate 15 is rotatably connected to the front end of the connecting rod 14. The sealing plate 15 is rotatably connected to the inner wall of the dust collection box 3. By setting the sealing plate 15, the dust collection box 3 and the air inlet box 4 are not connected to each other. A strip-shaped opening 21 is opened at the bottom of the sealing cover 6. When the sealing cover 6 moves downward and contacts the sealing plate 15, it will squeeze the sealing plate 15 downward, causing the sealing plate 15 to flip downward. At this time, the dust collection box 3 passes through the strip-shaped opening 21. The opening 21 is connected to the interior of the sealing cover 6, and under the filling of the sealing cover 6, the dust collection box 3 and the air inlet box 4 continue to be in a state of non-communication, so as to prevent the air entering the air inlet box 4 from flowing into the dust collection box 3 and thus reducing the amount of air actually participating in nitrogen production. When the sealing cover 6 continues to move downward, under the action of the abutment rod 11, the movable plate 8 is tilted, so that the dust swept on the movable plate 8 slides off and falls from the strip opening 21 into the dust collection box 3, thereby achieving the purpose of cleaning the filter plate 5 while producing nitrogen, so that the filter plate 5 always maintains a good ventilation effect during the nitrogen production process, thereby effectively improving the working efficiency of nitrogen production.
[0022] Both sets of limiting cylinders 12 have a first spring 16 fixedly installed on their bottom walls, and the front end of the first spring 16 is fixedly connected to the tail end of the limiting rod 13. By setting the first spring 16, the first spring 16 plays the role of resetting the limiting rod 13. When the sealing plate 15 flips downward, under the linkage of the connecting rod 14, the limiting rod 13 will slide downward along the inner wall of the limiting cylinder 12, thereby squeezing the first spring 16. When the sealing cover 6 moves upward, the potential energy stored in the first spring 16 begins to be released, so that the sealing plate 15 can rotate in the opposite direction to the movement of the sealing cover 6. When the sealing cover 6 is completely detached from the dust collection box 3, the filter plate 5 can continue to play the role of sealing the dust collection box 3 and the air inlet box 4, thereby ensuring that the dust collection box 3 and the air inlet box 4 always remain in a state of non-communication during the nitrogen generation process. Two sets of second springs 17 are fixedly installed at the bottom of the movable plate 8, and the tail end of the second spring 17 is fixedly connected to the inner side wall of the sealing cover 6. By setting the second spring 17, the second spring 17 plays the role of resetting the limiting rod 13. The movable plate 8 serves as a support and reset mechanism. When the abutment rod 11 pushes the movable plate 8, the movable plate 8 flips and squeezes the second spring 17. As the abutment rod 11 gradually disengages from the movable plate 8, the second spring 17 gradually returns to its original shape, thereby driving the movable plate 8 to reset. Two sets of sliders 9 are fixedly installed on one side of the sealing cover 6. The inner wall of one set of sliders 9 is threaded with a threaded rod 18, and the tail end of the threaded rod 18 is rotatably connected to the bottom wall of the air intake box 4. The inner wall of the other set of sliders 9 is slidably connected with a guide rod 19, and the front and tail ends of the guide rod 19 are fixedly connected to the top and bottom walls of the air intake box 4, respectively. A servo motor 20 is fixedly installed on the top of the air intake box 4, and the output end of the servo motor 20 is fixedly connected to the front end of the threaded rod 18. After the servo motor 20 is powered on, its output end can drive the threaded rod 18 to rotate. Under the action of thread engagement, the slider 9 drives the sealing cover 6 to move up and down, thereby driving the brush 7 to move up and down to clean the filter plate 5.
[0023] It should be noted that this utility model is a high-efficiency and energy-saving nitrogen generator. During use, the nitrogen generator body 2 sends air into the air inlet box 4 through a pipe and filters it through the filter plate 5. Then, the servo motor 20 is controlled to operate, causing the threaded rod 18 to rotate, which in turn causes the sealing cover 6 to slide downwards along one side of the filter plate 5. During this sliding process, the brush 7 cleans the dust on the filter plate 5, and the cleaned dust falls onto the movable plate 8. When the sealing cover 6 pushes the sealing plate 15 downwards, it causes the sealing plate 15 to deflect, thereby connecting the dust collection box 3 with the interior of the sealing cover 6. At this time, due to the filling effect of the sealing cover 6, the dust collection box 3 and the interior of the sealing cover 6 are connected. The air intake boxes 4 remain disconnected from each other to prevent air from flowing into the dust collection box 3. The sealing cover 6 continues to move downward, causing the movable plate 8 to tilt under the action of the abutment rod 11. This causes the dust on the movable plate 8 to slide off and fall into the dust collection box 3 through the strip opening 21, thereby achieving the purpose of cleaning the filter plate 5 while generating nitrogen, ensuring that the filter plate 5 always maintains good air permeability. Then, the threaded rod 18 is reversed, causing the sealing cover 6 to drive the brush 7 to move upward for cleaning. During the upward movement, the sealing plate 15 and the movable plate 8 will gradually return to their original positions due to the influence of the first spring 16 and the second spring 17.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
