A rotating rod 2 16 and a rotating rod 3 19 are rotatably installed on one side of a set of L-shaped plates 4. The rotating rod 2 16 is located above the rotating rod 3 19. The outer wall of the rotating rod 2 16 is fitted with a large transmission gear 17 and a small transmission gear 18. The driving toothed plate 15 meshes with the large transmission gear 17. The outer wall of the rotating rod 3 19 is fitted with a gear 20. The gear 20 meshes with the small transmission gear 18 and the toothed plate 13. A square locking hole is provided on the rotating shaft 14 to facilitate the insertion and driving of the square rod. A sliding block 22 is connected to the connecting plate 3. An installation plate 21 is slidably installed inside the sliding block 22. The toothed plate 13 is fixedly connected to the mounting plate 21. In use, the rocker arm is inserted into the square locking hole of the rotating shaft 14. Simultaneously, the operator rotates the square rod, which in turn rotates the rotating shaft 14. The rotation of the rotating shaft 14 drives the toothed plate 15 to rotate, which in turn drives the large transmission gear 17 to rotate. The large transmission gear 17 then drives the second rotating rod 16 to rotate, which in turn drives the small transmission gear 18 to rotate. The small transmission gear 18 then drives the gear 20 to rotate, which in turn moves the toothed plate 13. The toothed plate 13 moves the mounting plate 21 on the sliding block 22. Simultaneously, the movement of the toothed plate 13 moves the fixing device 12 and the pull rod 11, which in turn moves the windshield 10.The wind shield 10 drives the fixed plate 9 to move on the slide plate 8. When the wind shield 10 moves on the slide plate 8, the distance between the wind shield 10 and the bottom of the base plate 1 increases, allowing air to flow from the opening on the base plate 1 to the air outlet plate 7 for blowing out. Through the coordinated use of the slide plate 8, fixed plate 9, wind shield 10, pull rod 11, fixture 12, gear plate 13, rotating shaft 14, drive gear plate 15, rotating rod 16, large transmission gear 17, small transmission gear 18, rotating rod 19, gear 20, mounting plate 21, and slide block 22, it can...

Furthermore, the angle of the ventilation plate can be precisely controlled by cranking a lever, allowing for precise control of airflow. This enables the ventilation volume to be increased or decreased as needed, achieving better air exchange. The hand-cranked method is simple, requiring no complex electrical or electronic controls, making it suitable for environments requiring manual adjustment. This helps save energy and reduce carbon footprint, meeting modern energy conservation and environmental protection requirements.

[0017] Working principle: In use, the rocker arm is inserted into the square lock hole of the rotating shaft 14. At the same time, the operator drives the square rod to rotate, which drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 drives the drive gear plate 15 to rotate, which drives the transmission large gear 17 to rotate. The transmission large gear 17 drives the rotating rod 16 to rotate, which drives the transmission small gear 18 to rotate. The transmission small gear 18 drives the gear 20 to rotate, which drives the gear plate 13 to move. The gear plate 13 drives the mounting plate 21 to move on the sliding block 22. While the gear plate 13 is moving, it also drives the fixing device 12 and the pull rod 11 to move. The pull rod 11 drives the wind shield 10 to move, which drives the fixing plate 9 to move on the sliding plate 8. When the wind shield 10 moves on the sliding plate 8, the distance between the wind shield 10 and the bottom of the base plate 1 increases, allowing the air to flow from the through-hole on the base plate 1 to the air outlet plate 7 for blowing out.
