Description

Technical Field

[0001] The invention belongs to the technical field of ventilators, and in particular relates to a side-opening energy-saving and environment-friendly streamlined ventilator. Background Art

[0002] A side-opening ventilator is a ventilation device installed on a building's wall or roof. Through optimal airflow organization, it effectively introduces fresh air from outside and exhausts stale indoor air. Requiring no electricity, it relies on wind pressure and thermal pressure differentials to achieve ventilation, significantly reducing building energy consumption. Its structural design is rainproof and dustproof, ensuring stable ventilation, making it suitable for industrial plants, warehouses, public buildings, and other locations. By relying entirely on natural wind power, it reduces reliance on air conditioning and mechanical ventilation, thereby reducing carbon emissions. Its significant energy-saving and environmentally friendly features align with the concept of green building.

[0003] Research has found that when there is natural wind outdoors, the pressure at the top of the ventilator may be lower than the indoor pressure. At this time, the chimney effect will enhance the exhaust effect and improve the ventilation efficiency. However, the existing side-opening ventilator adopts a double-symmetrical inclined air flow channel design. Therefore, when natural wind blows horizontally across the top, one side of the channel can efficiently exhaust the air, but the other side may experience air backflow, thereby affecting the overall ventilation efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a side-opening energy-saving and environmentally friendly streamlined ventilator that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A side-opening energy-saving and environmentally friendly streamlined ventilator comprises a top plate with a through groove on the top, and also comprises: two symmetrically arranged inclined plates, which are fixedly connected to both sides of the top plate, wherein the front and rear sides of the top plate are fixedly connected to vertical plates, an inverted V-shaped plate is rotatably installed between the two vertical plates through a first rotating shaft, and an adjustment part for driving the inverted V-shaped plate to deflect is provided between the two vertical plates; two symmetrically arranged side plates are both fixedly connected between the two vertical plates, wherein a first gap is provided between the side plates and the top of the inclined plate, the two side plates are inclined to the inclined plate and the two sides of the inverted V-shaped plate, and the tops of the two vertical plates are connected to guide plates parallel to the inclined plates.

[0007] Preferably, a first channel is formed between the inverted V-shaped plate, the top plate and the side plates, a second channel connected to the first channel is formed at the connection between the guide plate and the side plates, and a third channel is formed between the guide plate and the inclined surface of the inverted V-shaped plate.

[0008] Preferably, the adjustment part includes a horizontal frame fixedly connected between the two vertical plates, a drive motor is fixedly mounted on the horizontal frame, a worm is fixedly mounted on the output shaft of the drive motor, and a worm wheel meshing with the worm is fixedly mounted on the lower end of the inverted V-shaped plate.

[0009] Furthermore, a photovoltaic panel is fixedly mounted on the upper end surface of the inverted V-shaped plate, a battery is fixedly mounted on the horizontal frame, the output end of the photovoltaic panel is connected to the battery, and the output end of the battery is connected to the power port of the drive motor.

[0010] Preferably, the top of the side panel is rotatably connected to a downward vertical plate through a rotating rod, a second gap is provided between the lower end of the vertical plate and the upper end surface of the inclined plate, the width of the first gap is greater than the width of the second gap, and a swinging part is provided on the side panel to push the vertical plate to swing.

[0011] Furthermore, the swinging part includes an oblique shaft rotatably connected to the side plate, the end of the oblique shaft is fixedly connected to a threaded rod, the outer wall of the side plate is fixedly connected to a guide rod parallel to the threaded rod, and a triangular area is formed between the vertical plate, the side plate and the oblique plate, a slide slidably connected to the guide rod is threadedly connected to the threaded rod, a push rod is rotatably connected to the slide, and the other end of the push rod is rotatably connected to the vertical plate, the threaded rod, the guide rod and the push rod are all located in the triangular area, and the inverted V-shaped plate is provided with a linkage part that drives the oblique shaft to rotate.

[0012] Furthermore, the linkage portion includes an arc-shaped rack fixedly connected to the bottom of the inverted V-shaped plate, the end of the oblique shaft passes through the first channel and is fixedly installed with a driven gear, and the driven gear is meshed and connected with the arc-shaped rack.

[0013] Furthermore, a short plate located in the first channel is fixedly connected to the inclined plate, and the short plate is inclined toward the second channel. The first gap is close to the short plate. When the inverted V-shaped plate rotates and tilts, one end of the inverted V-shaped plate presses on the short plate.

[0014] Furthermore, the guide plate is rotatably mounted on the side plate via a second rotating shaft, and transmission gears are fixedly mounted on both the second rotating shaft and the rotating rod, and the two transmission gears are meshed and connected.

[0015] Furthermore, a device box is fixedly connected between the two vertical plates by a bracket, a slider is slidably installed in the device box, a spring is installed between the slider and the inner wall of the device box, a reset controller for controlling the reset of the drive motor is installed in the middle of the inner wall of the device box, a forward controller and a reverse controller are respectively installed on both sides of the inner wall of the device box, and a thin plate perpendicular to the vertical plate is provided on the top of the device box, and the thin plate is connected to the slider through an L-shaped frame.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0017] 1. The present invention drives the inverted V-shaped plate to deflect counterclockwise by a driving motor, so that the inverted V-shaped plate will widen the first channel on the right side and narrow the first channel on the other side. As a result, most of the indoor air will flow into the first channel on the right side and then be discharged from the third channel on the right side. Since the third channel on the right side is basically parallel to the wind direction of the natural wind at this time, the third channel can discharge the indoor air more efficiently, and the first channel on the other side becomes narrower, so it is not easy for the natural wind to cause backflow into it.

[0018] 2. In the present invention, by setting the first gap and the second gap, part of the natural wind will pass through the second gap and the first gap in sequence and enter the first channel, and be guided to the second channel by the short plate. Therefore, the natural wind can assist the air in the second channel, so that it can be discharged from the third channel more efficiently, thereby improving ventilation efficiency.

[0019] 3. The present invention provides a short plate. When the inverted V-shaped plate deflects and tilts, the movable end on one side will rest on the short plate, thereby basically blocking the first channel, thereby completely sealing the first channel that is prone to backflow, thereby avoiding the backflow phenomenon and ensuring the ventilation efficiency of the ventilator.

[0020] 4. The present invention drives the arc-shaped rack to rotate synchronously through the inverted V-shaped plate, and the push rod pushes the vertical plate to deflect upward, so that the second gap between the vertical plate and the inclined plate will increase, and the angle between the vertical plate and the guide plate will also increase. Therefore, part of the natural wind can be blown more smoothly along the surface of the guide plate and the vertical plate to the upper port of the third channel, indirectly increasing the negative pressure at the upper port of the third channel and improving the efficiency of exhausting indoor air.

[0021] 5. When the vertical plate of the present invention is flipped upward, the rotating rod will drive another second rotating shaft to rotate through two mutually meshing transmission gears, and the second rotating shaft will drive the guide plate to deflect upward, so that the width of the third channel will also increase, thereby increasing the exhaust volume of the third channel, thereby ensuring the ventilation efficiency of the ventilator.

[0022] 6. The present invention guides the natural wind upward through the upwardly deflected guide plate, and the wind direction of the air discharged from the third channel will gradually approach the wind direction of the natural wind. This can reduce the natural wind resistance encountered when the air is exhausted and improve the ventilation efficiency of the ventilator. The guide plate on the other side will tilt downward and deflect, so that the width of the third channel on the other side will be reduced, and the natural wind will be less likely to flow back into the third channel.

[0023] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0035] Example 1: Reference Figures 1-8 A side-opening energy-saving and environmentally friendly streamlined ventilator includes a top plate 1 with a through slot 2 on the top, which is equivalent to the vent of the roof, and also includes: two symmetrically arranged inclined plates 3, which are fixedly connected to both sides of the top plate 1, and the inclined plates 3 are flush with the roof, wherein the front and rear sides of the top plate 1 are fixedly connected with vertical plates 34, and the vertical plates 34 are perpendicular to the roof, and an inverted V-shaped plate 5 is rotatably installed between the two vertical plates 34 through a first rotating shaft 4, and the inverted V-shaped plate 5 is equivalent to a reduced version of the roof, and the two sides of the inverted V-shaped plate 5 are respectively parallel to the two inclined plates 3 and are located directly above the through slot 2. A driving mechanism for the inverted V-shaped plate 5 to deflect is provided between the two vertical plates 34. Rotation adjustment part; two symmetrically arranged side panels 6 are fixedly connected between the two vertical panels 34, wherein a first gap 11 is provided between the side panels 6 and the top of the inclined panel 3, the first gap 11 is used to drain rainwater, the two side panels 6 are inclined at both sides of the inclined panel 3 and the inverted V-shaped panel 5, the tops of the two vertical panels 34 are connected with guide plates 7 parallel to the inclined panel 3, the guide plates 7 and the side panels 6 are combined into a transverse V-shaped panel, a first channel 8 is formed between the inverted V-shaped panel 5, the top panel 1 and the side panels 6, a second channel 9 connected to the first channel 8 is formed at the connection between the guide plate 7 and the side panel 6, and a third channel 10 is formed between the guide plate 7 and the inclined surface of the inverted V-shaped panel 5.

[0036] Specifically, during installation, the top plate 1 is fixed on the roof, and the ventilation grooves on the roof are aligned with the through grooves 2, and the inclined plate 3 is flush with the roof surface. Therefore, when in use, the high-temperature air in the house will flow upward into the through grooves 2, and then enter the first channel 8 under the guidance of the inverted V-shaped plate 5, and then enter the second channel 9 and the third channel 10 in turn under the guidance of the side plates 6 and the guide plates 7, and finally the hot air is discharged upward from the top of the inverted V-shaped plate 5 to complete the indoor ventilation. In rainy weather, rainwater will flow downward along the inverted V-shaped plate 5 to the side plates 6, and then flow from the side plates 6 to the inclined plate 3, and then pass through the first gap 11, and finally flow downward along the roof. When the wind blows, the side plates 6 and guide plates 7 on both sides can reduce the natural wind from flowing back into the first channel 8 When the natural wind blows basically vertically to the right side of the ventilator and the wind force reaches level 3 or above, the regulating part will drive the inverted V-shaped plate 5 to deflect counterclockwise, so that the inverted V-shaped plate 5 will widen the first channel 8 on the right and narrow the first channel 8 on the other side, so that most of the indoor air will flow into the first channel 8 on the right and then be discharged from the third channel 10 on the right. Since the third channel 10 on the right is basically parallel to the wind direction of the natural wind at this time, the third channel 10 can discharge the indoor air more efficiently, and the first channel 8 on the other side is narrowed, so the natural wind is not easy to cause backflow to it. On the contrary, when the natural wind blows to the left side of the ventilator, the regulating part will drive the inverted V-shaped plate 5 to deflect and tilt to the other side to enlarge the first channel 8 on the left and ensure the ventilation efficiency.

[0037] Example 2: Reference Figure 1-Figure 4 as well as Figure 6-Figure 8 , a side-opening energy-saving and environmentally friendly streamlined ventilator, which is basically the same as Example 1, further comprising:

[0038] The above-mentioned adjustment part includes a horizontal frame 13 fixedly connected between the two vertical plates 34, a drive motor 14 is fixedly mounted on the horizontal frame 13, a worm 40 is fixedly mounted on the output shaft of the drive motor 14, and a worm wheel 41 meshing with the worm 40 is fixedly mounted on the lower end of the inverted V-shaped plate 5.

[0039] Specifically, when the inverted V-shaped plate 5 needs to be deflected, the drive motor 14 is started, and the drive motor 14 will drive the worm 40 to rotate a fixed number of circles, and the worm 40 will drive the inverted V-shaped plate 5 to deflect counterclockwise through the worm gear 41. When the inverted V-shaped plate 5 needs to be deflected in the opposite direction, the output shaft of the drive motor 14 can be reversed.

[0040] A photovoltaic panel 37 is fixedly mounted on the upper end surface of the inverted V-shaped plate 5 , and a battery 39 is fixedly mounted on the horizontal frame 13 . The output end of the photovoltaic panel 37 is connected to the battery 39 , and the output end of the battery 39 is connected to the power port of the drive motor 14 .

[0041] Specifically, during use, the photovoltaic panel 37 can charge the battery 39 with the help of sunlight, and the battery 39 can power the drive motor 14, so that the drive motor 14 can work without an external power supply, and the entire device will be more energy-saving and environmentally friendly.

[0042] A device box 15 is fixedly connected between the two vertical plates 34 through a bracket, and a slider 19 is slidably installed in the device box 15. A spring 20 is installed between the slider 19 and the inner wall of the device box 15. A reset controller 18 for controlling the reset of the drive motor 14 is installed in the middle of the inner wall of the device box 15. A forward controller 16 and a reverse controller 17 are respectively installed on both sides of the inner wall of the device box 15. A thin plate 21 perpendicular to the vertical plate 34 is provided on the top of the device box 15. The thin plate 21 is connected to the slider 19 through an L-shaped frame 22. The reset controller 18, forward controller 16 and reverse controller 17 are respectively used to control the rotation reset, reverse fixed number of circles and forward fixed number of circles of the drive motor 14. The drive motor 14 is a servo motor and is controlled by a PLC controller.

[0043] Specifically, when the natural wind blows basically vertically to the right side of the ventilator and the wind force reaches level 3 or above, the natural wind will push the thin plate 21 to translate, and the thin plate 21 will drive the slider 19 to translate in the device box 15 through the L-shaped frame 22, and the slider 19 will move from the middle of the device box 15 to the left side of the device box 15, so that the slider 19 no longer presses the reset controller 18, but presses on the forward rotation controller 16, so that the drive motor 14 will drive the worm 40 to rotate a fixed number of circles, and the worm 40 will drive the inverted V-shaped plate 5 to deflect counterclockwise through the worm gear 41. Conversely, when the natural wind blows to the left side of the ventilator, the thin plate 21 will translate to the right again, so that the slider 19 will squeeze the reset controller 18 and the reversal controller 17 on the right in turn. When the reset controller 18 is pressed, the output shaft of the drive motor 14 will be reversed and reset. When the reversal controller 17 is pressed, the output shaft of the drive motor 14 will continue to reverse until the inverted V-shaped plate 5 deflects and tilts to the other side.

[0044] Example 3: Reference Figures 1-8 , a side-opening energy-saving and environmentally friendly streamlined ventilator, which is basically the same as Example 2, further comprising:

[0045] The top of the side panel 6 is rotatably connected to a downward vertical vertical panel 24 through a rotating rod 25. A second gap 35 is provided between the lower end of the vertical panel 24 and the upper end surface of the inclined panel 3. The setting of the vertical panel 24 will require natural wind to pass through the second gap 35 and the first gap 11 in sequence before entering the first channel 8. The width of the first gap 11 is greater than the width of the second gap 35. The width of the first gap 11 can allow most leaves to pass through. A swinging part for pushing the vertical panel 24 to swing is provided on the side panel 6. The swinging part includes an oblique shaft 26 rotatably connected to the side panel 6. The end of the oblique shaft 26 is fixedly connected to a threaded rod 27. The outer wall of the side panel 6 is fixedly connected to a guide rod 33 parallel to the threaded rod 27. A triangular area 29 is formed between the vertical plate 24, the side plate 6 and the inclined plate 3. A slide 28 is threadedly connected to the threaded rod 27 and is slidably connected to the guide rod 33. A push rod 30 is rotatably connected to the slide 28. The other end of the push rod 30 is rotatably connected to the vertical plate 24. The threaded rod 27, the guide rod 33 and the push rod 30 are all located in the triangular area 29 to prevent the threaded rod 27 from being contaminated and affected by external connections. A linkage part for driving the inclined shaft 26 to rotate is provided on the inverted V-shaped plate 5. The linkage part includes an arcuate rack 32 fixedly connected to the bottom of the inverted V-shaped plate 5. The end of the inclined shaft 26 passes through the first channel 8 and is fixedly installed with a driven gear 31. The driven gear 31 is meshed with the arcuate rack 32.

[0046] Specifically, when the inverted V-shaped plate 5 deflects, it will also drive the arc-shaped rack 32 to rotate synchronously, and the arc-shaped rack 32 will drive the driven gear 31 to rotate, and the driven gear 31 will rotate through the inclined shaft 26 and the threaded rod 27, and the threaded rod 27 will drive the slide 28 to translate along the surface of the guide rod 33, and push the vertical plate 24 to deflect upward through the push rod 30, so that the second gap 35 between the vertical plate 24 and the inclined plate 3 will increase, and the angle between the vertical plate 24 and the guide plate 7 will also increase, so that part of the natural wind can be blown more smoothly along the surface of the guide plate 7 and the vertical plate 24 to the upper port of the third channel 10, indirectly increasing the third channel 10, improves the efficiency of exhausting indoor air, and more natural wind will pass through the second gap 35 with an enlarged opening, and then pass through the first gap 11 with a smaller width, and enter the second channel 9 under the guidance of the short plate 12. More natural wind will cause a stronger acceleration effect in the second channel 9, so that the third channel 10 can exhaust indoor air more efficiently, and the ventilation effect of the ventilator will be further improved; on the other side, the arc-shaped rack 32 will drive the driven gear 31 to reverse, so that the slide 28 will pull the vertical plate 24 through the push rod 30, so that the width of the second gap 35 between the vertical plate 24 and the inclined plate 3 is reduced.

[0047] The guide plate 7 is rotatably mounted on the side plate 6 via the second rotating shaft 23 . Transmission gears 36 are fixedly mounted on both the second rotating shaft 23 and the rotating rod 25 . The two transmission gears 36 are meshed and connected.

[0048] Specifically, when the vertical plate 24 flips upward, the vertical plate 24 will drive the rotating rod 25 to rotate synchronously, and the rotating rod 25 will drive the other second rotating shaft 23 to rotate through two mutually meshing transmission gears 36. The second rotating shaft 23 will drive the guide plate 7 to deflect upward, so the width of the third channel 10 will also increase, thereby improving the exhaust volume of the third channel 10, thereby ensuring the ventilation efficiency of the ventilator, and the upward deflected guide plate 7 will guide the natural wind upward, and the wind direction of the air discharged from the third channel 10 will gradually approach the wind direction of the natural wind, which can reduce the natural wind resistance encountered during air exhaust and improve the ventilation efficiency of the ventilator, and the guide plate 7 on the other side will tilt and deflect downward, so the width of the third channel 10 on the other side will be reduced, and natural wind will be less likely to flow back into the third channel 10.

[0049] During use, it was found that the swinging inverted V-shaped plate 5, vertical plate 24 and guide plate 7 can repel insects and birds, making the ventilator less susceptible to the influence of insects and birds, reducing the number of maintenance times, and being able to shake off leaves and garbage that fall onto the inverted V-shaped plate 5 and guide plate 7.

[0050] During use, it was also found that the leaves and garbage remaining on the inverted V-shaped plate 5 would slide down the side plate 6 to the inclined plate 3. Since the width of the first gap 11 is greater than the second gap 35, some leaves and garbage would not be able to pass through the second gap 35 and would remain in the triangular area 29. When the vertical plate 24 deflects upward, the second gap 35 with an increased width can efficiently discharge the leaves and garbage, preventing the second gap 35 from being blocked and affecting the drainage efficiency.

[0051] A soft rubber sheet 38 is fixedly connected to the outer wall of the guide plate 7 near the connection end, and the other end of the rubber sheet 38 is fixedly connected to the vertical plate 24. The rubber sheet 38 prevents rainwater from flowing into the second channel 9 from the gap between the guide plate 7 and the vertical plate 24.

[0052] Example 4: Reference Figure 3-Figure 8 , a side-opening energy-saving and environmentally friendly streamlined ventilator, which is basically the same as Example 3, further comprising:

[0053] A short plate 12 located in the first channel 8 is fixedly connected to the above-mentioned inclined plate 3. The short plate 12 is inclined toward the second channel 9. The first gap 11 is close to the short plate 12. When the inverted V-shaped plate 5 rotates and tilts, one end of the inverted V-shaped plate 5 presses on the short plate 12.

[0054] Specifically, due to the setting of the short plate 12, when the inverted V-shaped plate 5 is deflected and tilted, the movable end on one side will rest on the short plate 12, thereby basically blocking the first channel 8, and then completely closing the first channel 8 that is prone to backflow, thereby avoiding the backflow phenomenon and ensuring the ventilation efficiency of the ventilator.

[0055] The working principle of the present invention is as follows: during installation, the top plate 1 is fixed to the roof, and the ventilation slots on the roof are aligned with the through slots 2, and the inclined plate 3 is flush with the roof surface. Therefore, when in use, the hot air in the room will flow upward into the through slots 2, and then enter the first channel 8 under the guidance of the inverted V-shaped plate 5, and then enter the second channel 9 and the third channel 10 in sequence under the guidance of the side plate 6 and the guide plate 7. Finally, the hot air is discharged upward from the top of the inverted V-shaped plate 5, thus completing the indoor ventilation work. In rainy weather, rainwater will flow downward along the inverted V-shaped plate 5 to the side plate 6. Then it flows from the side panel 6 to the inclined panel 3, and then passes through the first gap 11 and the second gap 35 in turn, and finally flows downward along the roof. When the wind blows, the side panels 6 and the guide plates 7 on both sides can reduce the backflow of natural wind into the first channel 8. Due to the setting of the first gap 11 and the second gap 35, part of the natural wind will pass through the second gap 35 and the first gap 11 in turn and enter the first channel 8, and be guided to the second channel 9 by the short plate 12. Therefore, the natural wind can assist the air in the second channel 9, so that it can be discharged from the third channel 10 more efficiently, thereby improving the ventilation efficiency.

[0056] When the natural wind blows basically vertically to the right side of the ventilator and the wind force reaches level 3 or above, the natural wind will push the thin plate 21 to move horizontally, and the thin plate 21 will drive the slider 19 to move horizontally in the device box 15 through the L-shaped frame 22, and the slider 19 will move from the middle of the device box 15 to the left side of the device box 15, so that the slider 19 no longer presses on the reset controller 18, but presses on the forward controller 16, so the drive motor 14 will drive the worm 40 to rotate a fixed number of circles, and the worm 40 will drive the inverted V-shaped plate 5 to deflect counterclockwise through the worm gear 41, so that the inverted V-shaped plate 5 will widen the first channel 8 on the right and narrow the first channel 8 on the other side, so that most of the indoor air will flow into the first channel 8 on the right, and then from the right The third channel 10 is discharged. Since the third channel 10 on the right side is basically parallel to the direction of the natural wind at this time, the third channel 10 can discharge the indoor air more efficiently, and the first channel 8 on the other side becomes narrower, so the natural wind is not easy to cause backflow to it. On the contrary, when the natural wind blows to the left side of the ventilator, the thin plate 21 will translate to the right side, so that the slider 19 will squeeze the reset controller 18 and the reversal controller 17 on the right side in turn. When the reset controller 18 is pressed, the output shaft of the drive motor 14 will be reversed and reset. When the reversal controller 17 is pressed, the output shaft of the drive motor 14 will continue to reverse until the inverted V-shaped plate 5 deflects and tilts to the other side, so that the first channel 8 on the left side is enlarged to ensure ventilation efficiency.

[0057] When the inverted V-shaped plate 5 deflects, it will also drive the arc-shaped rack 32 to rotate synchronously, and the arc-shaped rack 32 will drive the driven gear 31 to rotate. The driven gear 31 will rotate through the inclined shaft 26 and the threaded rod 27, and the threaded rod 27 will drive the slide 28 to translate along the surface of the guide rod 33, and push the vertical plate 24 to deflect upward through the push rod 30, so that the second gap 35 between the vertical plate 24 and the inclined plate 3 will increase, and the angle between the vertical plate 24 and the guide plate 7 will also increase, so that part of the natural wind can be blown more smoothly along the surface of the guide plate 7 and the vertical plate 24 to the upper port of the third channel 10, indirectly increasing the third channel 10. The negative pressure at the upper port improves the efficiency of exhausting indoor air, and more natural wind will pass through the second gap 35 with an enlarged opening, and then pass through the first gap 11 with a smaller width, and enter the second channel 9 under the guidance of the short plate 12. More natural wind will cause a stronger acceleration effect in the second channel 9, so that the third channel 10 can exhaust indoor air more efficiently, and the ventilation effect of the ventilator will be further improved; on the other side, the arc-shaped rack 32 will drive the driven gear 31 to reverse, so that the slide 28 will pull the vertical plate 24 through the push rod 30, so that the width of the second gap 35 between the vertical plate 24 and the inclined plate 3 is reduced.
