DETAILED DESCRIPTION

[0032] The present invention provides Figures 1 to 8 The device, which shows an adjustable air volume vent, comprises a first tube 1, a second tube 2, and a mounting plate 3. The first tube 1 is connected to the second tube 2, and the mounting plate 3 is fixedly connected to the end of the second tube 2 away from the first tube 1. The mounting plate 3 is provided with an outlet slot 4 for discharging air, which is connected to the second tube 2. In actual use, the first tube 1 is connected to the HVAC outlet, and the mounting plate 3 is mounted on the building with screws. Air is discharged through the first tube 1, the second tube 2, and the outlet slot 4.

[0033] Reference Figure 3 As shown, a sliding chamber 5 is provided inside the mounting plate 3, and a baffle 6 is slidingly provided inside the sliding chamber 5. A square groove 7 cooperating with the air outlet slot 4 is provided on the baffle 6. A guide bar 8 is rotatably connected inside the square groove 7. There are multiple guide bars 8, and the multiple guide bars 8 are evenly distributed. The guide bars 8 are provided to adjust the wind direction and can be manually adjusted by the operator.

[0034] When the square slot 7 corresponds to the air outlet slot 4 , air can be discharged. When the baffle 6 blocks the air outlet slot 4 , the second tube body 2 is protected.

[0035] Reference Figure 3 As shown, a guide block 9 is provided inside the second tube body 2. The guide block 9 can rotate or slide inside the second tube body 2. A ventilation channel 10 is provided on the guide block 9. The ventilation channel 10 is arranged at an angle, has a large windward area, and facilitates the movement of the guide block 9 when affected by the airflow.

[0036] A fixing plate 21 is fixedly connected to the inner wall of the first tube body 1. A circular groove 17 is formed in the fixing plate 21. A rotating rod 18 is disposed within the circular groove 17. A fan blade 19 is fixedly connected to the rotating rod 18. A connecting plate 20 is fixedly connected to the guide block 9. The rotating rod 18 is fixedly connected to the connecting plate 20. A circular block 23 is fixedly connected to the end of the rotating rod 18 away from the connecting plate 20. A spring 24 is mounted on the rotating rod 18. One end of the spring 24 abuts against the circular block 23, and the other end of the spring 24 abuts against the fixing plate 21.

[0037] During ventilation, the airflow acts on the inclined surface of the ventilation channel 10, pushing the guide block 9 to move toward the mounting plate 3. With the cooperation of the connecting plate 20, the rotating rod 18 moves synchronously and the spring 24 contracts. At the same time, the fan blades 19 drive the guide block 9 to rotate through the rotating rod 18, changing the position of the air outlet end of the ventilation channel 10, thereby adjusting the air volume in the second tube body 2 and achieving uniform air outlet.

[0038] When ventilation is stopped, the restoring force of the spring 24 causes the guide block 9 and other structures to be restored.

[0039] Reference Figure 3 、 Figure 4 、 Figure 5 As shown, a circular sleeve 25 is slidably provided inside the second tube body 2, and the circular sleeve 25 is fitted on the guide block 9, and the guide block 9 closes the inner cavity of the circular sleeve 25 (refer to Figure 7 ), when in use, a rubber pad can be set between the guide block 9 and the round sleeve 25 to reduce wear and improve the sealing effect.

[0040] The circular sleeve 25 is located on the side of the guide block 9 close to the mounting plate 3, and the inner sliding of the circular sleeve 25 is provided with an air pipe 28 (the side of the circular sleeve 25 close to the guide block 9 is provided with an annular groove adapted to the air pipe 28, refer to Figure 7 ), the air pipe 28 is communicated with the circular sleeve 25, and the air pipe 28 is fixedly connected to the guide block 9. When the guide block 9 rotates, the air pipe 28 is driven to rotate synchronously, and the air pipe 28 slides inside the circular sleeve 25, and the air pipe 28 is always communicated with the circular sleeve 25.

[0041] A slip ring 11 is slidably mounted on the exterior of the second tube 2. A magnet 12 is fixedly embedded in the inner ring of the slip ring 11. The magnet 12 cooperates with a circular sleeve 25. The circular sleeve 25 can be made of stainless steel, which is susceptible to magnetism, while the second tube 2 is made of plastic, which is not susceptible to magnetism. This material can be adjusted based on specific usage. When the guide block 9 drives the circular sleeve 25 to move, the magnet 12 drives the slip ring 11 to move synchronously.

[0042] In addition, the magnetic force of the magnet 12 is appropriately set to ensure that the magnet 12 cooperates with the circular sleeve 25, and structures such as balls can be set between the inner ring of the slip ring 11 and the outer wall of the second tube body 2 to reduce friction. It can be adjusted according to specific usage conditions. Reducing friction is an existing common technology and will not be elaborated here.

[0043] A support plate 13 is fixedly connected to the slip ring 11. A first air cylinder 15 is fixedly connected to the side of the mounting plate 3 near the second tube 2. A first slide post 14 is slidably connected to the interior of the first air cylinder 15. The first slide post 14 extends through the end of the first air cylinder 15 away from the mounting plate 3 and is fixedly connected to the mounting plate 3. An air hole 16 is formed at the end of the first air cylinder 15 away from the first slide post 14, and the first air cylinder 15 communicates with the sliding chamber 5 through the air hole 16.

[0044] When the guide block 9 moves toward the mounting plate 3, the slip ring 11 moves synchronously, and the slip ring 11 squeezes the first sliding column 14 and recovers it to the inside of the first air cylinder 15. The gas inside the first air cylinder 15 enters the interior of the sliding chamber 5 through the air hole 16, pushing the baffle 6 to slide inside the sliding chamber 5. The square groove 7 corresponds to the position of the air outlet groove 4, and can provide air outlet.

[0045] After the guide block 9 and other structures are restored, the baffle 6 blocks the air outlet slot 4 to protect the second tube body 2 .

[0046] The present invention provides structures such as a guide block 9 and a baffle 6, utilizes the action of airflow to drive the guide block 9 to rotate, and changes the position of the air outlet end of the ventilation channel 10, thereby adjusting the air volume in the second tube body 2 to achieve uniform air outlet, and at the same time drives the baffle 6 to move to achieve protection for the second tube body 2.

[0047] Considering that the second tube body 2 is provided with structures such as the guide block 9, which affects the instantaneous flow, the inner diameter of the second tube body 2 is larger than the inner diameter of the first tube body 1, so that the instantaneous flow inside the second tube body 2 and the first tube body 1 are consistent.

[0048] Taking into account that during ventilation, the airflow will act on the inclined surface of the ventilation channel 10, pushing the guide block 9 to move toward the mounting plate 3, in order to reduce the wear of the guide block 9, an airbag 30 is fixedly connected to the inner wall of the ventilation channel 10. During ventilation, the airflow will act on the airbag 30, reducing the wear of the guide block 9.

[0049] Reference Figure 3 、 Figure 4 As shown, the airbag 30 is wavy in shape, which expands the windward area.

[0050] A second gas channel 29 is defined inside the guide block 9 . One end of the second gas channel 29 is communicated with the air pipe 28 , and the other end of the second gas channel 29 is communicated with the air bag 30 .

[0051] The second cylinder 27 is fixedly connected to the inner wall of the second pipe body 2, and is located on the side of the flow guide block 9 close to the mounting plate 3. The second cylinder 27 is internally slidably provided with a second sliding column 22, and the second sliding column 22 penetrates the second cylinder 27 at one end close to the flow guide block 9. A first gas passage 26 is formed in the second sliding column 22, and the second cylinder 27 is in communication with the circular sleeve 25 through the first gas passage 26.

[0052] The second cylinder 27 and the second sliding column 22 are arranged so that the circular sleeve 25 can only slide in the interior of the second pipe body 2 and cannot rotate.

[0053] During ventilation, the airflow acts on the inclined surface of the ventilation passage 10, pushes the flow guide block 9 to move towards the mounting plate 3, and the circular sleeve 25 moves synchronously, so that the second sliding column 22 is recovered into the interior of the second cylinder 27. The gas in the interior of the second cylinder 27 enters the interior of the air bag 30 through the first gas passage 26 and the second gas passage 29, so that the air bag 30 is inflated, and the buffering effect is ensured.

[0054] After the flow guide block 9 and other structures are reset, the gas in the interior of the air bag 30 flows back to the interior of the second cylinder 27 through the second gas passage 29 and the first gas passage 26, the air bag 30 is contracted, and the situation of continuous inflation is avoided, so that the service life is prolonged.

[0055] Working principle: during ventilation, the airflow acts on the inclined surface of the ventilation passage 10, pushes the flow guide block 9 to move towards the mounting plate 3, and under the cooperation of the connecting plate 20, the rotating rod 18 moves synchronously, and the spring 24 is contracted; at the same time, the fan blade 19 drives the flow guide block 9 to rotate through the rotating rod 18, changes the position of the air outlet end of the ventilation passage 10, adjusts the air volume in the second pipe body 2, and realizes uniform air outlet.

[0056] When the flow guide block 9 moves towards the mounting plate 3, the sliding ring 11 moves synchronously, the sliding ring 11 extrudes the first sliding column 14 to be recovered into the interior of the first cylinder 15, the gas in the interior of the first cylinder 15 enters the interior of the sliding chamber 5 through the air hole 16, pushes the baffle 6 to slide in the interior of the sliding chamber 5, and the square groove 7 corresponds to the air outlet groove 4 in position, so that the air outlet is provided.

[0057] At the same time, the airflow acts on the inclined surface of the ventilation passage 10, pushes the flow guide block 9 to move towards the mounting plate 3, the circular sleeve 25 moves synchronously, so that the second sliding column 22 is recovered into the interior of the second cylinder 27, the gas in the interior of the second cylinder 27 enters the interior of the air bag 30 through the first gas passage 26 and the second gas passage 29, so that the air bag 30 is inflated, and the buffering effect is ensured; after the flow guide block 9 and other structures are reset, the gas in the interior of the air bag 30 flows back to the interior of the second cylinder 27 through the second gas passage 29 and the first gas passage 26, the air bag 30 is contracted, and the situation of continuous inflation is avoided, so that the service life is prolonged.
