Example

[0028] Reference Figure 1 , Figure 2 and Figure 3 This utility model discloses a roof ventilation structure, including a base plate 1. A ventilation device 2 is provided on the top of the base plate 1. The ventilation device 2 includes a through hole 3. A wind roller 4 is provided inside the through hole 3. A sealing ring 5 is provided on one side of the through hole 3. A sealing plate 6 is provided on the top of the sealing ring 5. A groove 7 is provided inside the sealing plate 6. A connecting rod 8 is provided on one side of the sealing plate 6. A connecting plate 9 and a mounting box 10 are respectively provided at both ends of the connecting rod 8. A limiting hole 11 is provided inside the connecting plate 9. In this embodiment, the through hole 3 facilitates airflow, the sealing ring 5 improves the sealing performance, and the groove 7 engages the sealing ring.

[0029] Reference Figure 1 and Figure 2The air roller 4 is rotatably connected to the inside of the through hole 3, which is opened inside the base plate 1. The sealing ring 5 is fixedly connected to the base plate 1. The mounting box 10 and the connecting plate 9 are both fixedly connected to the top of the base plate 1. In this embodiment, the connecting plate 9 plays a limiting role.

[0030] Reference Figure 1 and Figure 2 The mounting box 10 has a limiting hole 11 inside, and the connecting rod 8 is rotatably connected to the inside of the limiting hole 11. In this embodiment, the connecting rod 8 plays a transmission role.

[0031] Reference Figure 3 The mounting box 10 is equipped with a drive device 12, which includes a transmission gear 13. A drive motor 14 is provided on one side of the transmission gear 13, and a control box 15 is provided on one side of the drive motor 14. The transmission gear 13 is fixedly connected to the connecting rod 8, and the drive motor 14 is fixedly connected to the inside of the mounting box 10. In this embodiment, the mounting box 10 serves to fix the drive motor 14, the transmission gear 13 serves to drive the connecting rod 8 to rotate, and the control box 15 serves to control the switch of the drive motor 14.

[0032] Reference Figure 4 A dustproof device 16 is provided on the top of the sealing plate 6. The dustproof device 16 includes a rubber plate 17. Fixing plates 20 are provided on both sides of the rubber plate 17. The fixing plates 20 have mounting holes 19 inside. A limiting plate 18 is provided on the top of the fixing plate 20. Fixing bolts 21 are provided inside the limiting plate 18. The rubber plate 17 is fixedly connected to the fixing plate 20. The fixing bolts 21 are engaged inside the mounting holes 19. The rubber plate 17 is movably connected to the top of the sealing plate 6. In this embodiment, the rubber plate 17 serves to cover the sealing plate 6, the fixing plate 20 serves to facilitate the fixing of the rubber plate, and the fixing bolts 21 serve to connect the fixing plate 20.

[0033] The implementation principle of this embodiment is as follows:

[0034] When ventilation is needed, the staff sends a signal to the control box 15. When the control box 15 receives the signal, it controls the drive motor 14 to start working and drives the transmission gear 13 to rotate (there are two transmission gears 13, which mesh with each other). The drive motor 14 drives one of the transmission gears 13 to rotate, and the other transmission gear 13 will also rotate together. The transmission gear 13 drives the connecting rod 8 to rotate, and the connecting rod 8 drives the sealing plate 6 to rotate. After the sealing plate 6 rotates to a certain extent, the drive motor 14 stops working, and the hot air inside the room rises (because hot air is lighter than cold air, it will rise, while cold air will sink). The continuously rising hot air will push the wind roller 4 to rotate. The wind roller 4 can accelerate the air flow during the rotation process.

[0035] When it is necessary to close the through hole 3, the drive motor 14 drives the transmission gear 13 to rotate again, and makes the sealing plate 6 completely fit with the bottom plate 1. After the sealing plate 6 fits with the bottom plate 1, the sealing ring 5 will be engaged with the inside of the groove 7 to achieve the sealing effect.

[0036] When the sealing plate 6 is rotated to open the through hole 3, the inner middle part of the rubber plate 17 will be folded, and a gap will appear between the rubber plate 17 and the sealing plate 6. When the sealing plate 6 is closed, the rubber plate 17 will be stretched, straightening the folds of the rubber plate 17, and the rubber plate 17 will fit against the top of the sealing plate 6 for dust prevention. After the sealing plate 6 is completely closed, the two sides of the rubber plate 17 can be sealed by using the connecting plate 9 in conjunction with the mounting box 10.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] The use of the air roller 4 and the through hole 3 facilitates ventilation. The use of the sealing plate 6, the groove 7, and the sealing ring 5 controls the opening and closing of the through hole 3. The use of the connecting rod 8, the mounting box 10, and the limiting hole 11 facilitates the rotation of the sealing plate 6. The use of the drive motor 14 and the transmission gear 13 drives the connecting rod 8 to rotate. By using the above structure, the opening and closing of the through hole 3 can be controlled, thereby controlling the ventilation time. The addition of the rubber plate 17 facilitates the covering of the sealing plate 6. The use of the fixing plate 20 and the through hole 3 facilitates the connection of the fixing bolt 21. The use of the limiting plate 18 and the fixing bolt 21 secures the rubber plate 17. By using the above structure, dust can be effectively prevented from accumulating inside the structure, thus avoiding dust interference.

[0039] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
