A moving block 28 is threadedly sleeved on the outer surface of the screw rod 26. One end of the moving block 28 passes through the air outlet pipe 1 and is fixedly connected to the connecting plate 24. One end of the air outlet pipe 1 is provided with a movable groove 29 for cooperating with the moving block 28. When the air outlet volume of the HVAC needs to be adjusted, the knob 27 on the support block 25 is rotated, and the knob 27 drives the screw rod 26 to rotate. Since the screw rod 26 is threadedly connected to the moving block 28, and the moving block 28 is restricted by the movable groove 29 and cannot rotate, it can only move up and down along the screw rod 26. When the moving block 28 moves, it drives the connecting plate 24 to move synchronously, and the movement of the connecting plate 24 further drives the gear plate 23 to move. The tooth plate 23 is meshed with multiple gears 22. When the tooth plate 23 moves, it drives the gear 22 to rotate. The gear 22 is fixed on the rotating column 21, and the rotating column 21 is rotatably connected to the inner wall of the air outlet duct 1. Therefore, the rotation of the gear 22 will drive the rotating column 21 to rotate. The rotation of the rotating column 21 causes the wind shield 2 to rotate. By adjusting the angle of the wind shield 2, the ventilation area of the air outlet duct 1 can be changed, thereby achieving the adjustment of the air volume. The seven wind shields 2 are distributed at equal intervals up and down, and the air volume can be adjusted more evenly. Through the cooperation of mechanical structures such as the knob 27, the screw rod 26, the moving block 28, the tooth plate 23, the gear 22 and the wind shield 2, the air volume can be accurately adjusted. The user can easily adjust the angle of the wind shield 2 according to actual needs, thereby controlling the size of the air volume and meeting the HVAC usage requirements in different environments.
[0018] A T-shaped bar 210 is fixedly provided at one end of the connecting plate 24, and a limit frame 211 is fixedly provided on the inner wall of one side of the air outlet duct 1. One end of the T-shaped bar 210 is slidably connected to the limit frame 211, and a groove 212 is provided on one side of the lower inner wall of the air outlet duct 1 for cooperating with the connecting plate 24 and the tooth plate 23. The T-shaped bar 210 at one end of the connecting plate 24 slides in the limit frame 211 to ensure the stability of the movement of the connecting plate 24, and the groove 212 can cooperate with the connecting plate 24 to move to a lower position.
[0019] Example 2: Figure 3 As shown, both ends of the air outlet pipe 1 and the ventilation pipe 3 are fixed with connecting blocks 11, and the two corresponding connecting blocks 11 are connected by bolts. A filter plate 31 is embedded on the lower side of one end of the ventilation pipe 3, and a clamping plate 32 is fixed on both ends of the filter plate 31. One end of the ventilation pipe 3 is provided with two card slots 33 used to cooperate with the clamping plate 32. Both ends of the ventilation pipe 3 are fixed with mounting strips 34, and the mounting strips 34 are connected to the corresponding clamping plates 32 by bolts. When air enters the air outlet pipe 1 from the ventilation pipe 3, the filter plate 31 on the lower side of one end of the ventilation pipe 3 is connected to the air. The air is filtered to remove dust and other impurities in the air. The ventilation pipe 3 and the air outlet pipe 1 are connected by the bolts on the connecting block 11, which is convenient for disassembly and firmly fixed. The filter plate 31 is preliminarily positioned by the clamping plates 32 at both ends and the clamping grooves 33 on the ventilation pipe 3, and then fixed by the bolt connection between the mounting strip 34 and the clamping plate 32 to ensure the firmness of the installation of the filter plate 31. In this way, the filter plate 31 can be removed after the air outlet pipe 1 is disassembled, which allows the user to regularly clean or replace the filter plate 31 to ensure the filtering effect and extend the service life of the equipment.
[0020] Working principle: When the air volume of the HVAC needs to be adjusted, turn the knob 27 on the support block 25, and the knob 27 drives the screw rod 26 to rotate. Since the screw rod 26 is threadedly connected to the moving block 28, and the moving block 28 is restricted by the movable groove 29 and cannot rotate, it can only move up and down along the screw rod 26. When the moving block 28 moves, it drives the connecting plate 24 to move synchronously, and the movement of the connecting plate 24 further drives the gear plate 23 to move. The toothed plate 23 is meshed with a plurality of gears 22. When the toothed plate 23 moves, the gear 22 is driven to rotate. The gear 22 is fixed on the rotating column 21, and the rotating column 21 is rotatably connected to the inner wall of the air outlet duct 1. Therefore, the rotation of the gear 22 drives the rotating column 21 to rotate. The rotation of the rotating column 21 causes the wind shield 2 to rotate. By adjusting the angle of the wind shield 2, the ventilation area of the air outlet duct 1 can be changed, thereby achieving the adjustment of the air volume. The seven wind shields 2 are evenly spaced up and down, and the air volume can be adjusted more evenly. Through the cooperation of the mechanical structures such as the knob 27, the screw rod 26, the moving block 28, the toothed plate 23, the gear 22 and the wind shield 2, the air volume can be accurately adjusted. The user can easily adjust the angle of the wind shield 2 according to actual needs, thereby controlling the size of the air volume and meeting the HVAC requirements in different environments.
[0021] The T-shaped bar 210 at one end of the connecting plate 24 slides in the limiting frame 211 to ensure the stability of the movement of the connecting plate 24, while the groove 212 can cooperate with the connecting plate 24 to move to a lower position;
[0022] When air enters the outlet pipe 1 from the ventilation pipe 3, the filter plate 31 on the lower side of one end of the ventilation pipe 3 filters the air to remove dust and other impurities in the air. The ventilation pipe 3 and the outlet pipe 1 are connected by the bolts on the connecting block 11, which is convenient for disassembly and firmly fixed. The filter plate 31 is preliminarily positioned by the clamping plates 32 at both ends and the clamping grooves 33 on the ventilation pipe 3, and then fixed by the bolt connection between the mounting strip 34 and the clamping plate 32 to ensure the firmness of the installation of the filter plate 31. In this way, the filter plate 31 can be removed after the outlet pipe 1 is disassembled, which allows the user to regularly clean or replace the filter plate 31 to ensure the filtering effect and extend the service life of the equipment.
