[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3A ventilated door / window lintel includes a lintel panel 1. Multiple ventilation holes 2 are provided through the lower half of the lintel panel 1, allowing ventilation. The ventilation holes 2 are arranged in two rows, with the upper and lower rows staggered laterally. Two sets of side panels 3 are fixedly installed on the back of the lintel panel 1, distributed left and right. L-shaped grooves 4 are provided through the surface of the side panels 3, and a baffle 5 is provided between the two sets of side panels 3.

[0024] Please see Figure 1-3 A sliding post 6 is fixedly installed on the middle of both sides of the baffle 5. The sliding post 6 is slidably connected in the L-shaped sliding groove 4. Multiple sealing posts 7 are fixedly installed on the front side of the baffle 5. When the sliding post 6 slides along the upper half of the L-shaped sliding groove 4, the sealing post 7 slides against the back of the lintel 1. The sealing post 7 corresponds one-to-one with the vent hole 2, and the sealing post 7 is inserted into the vent hole 2. The diameter of the sealing post 7 is equal to the diameter of the vent hole 2, and the length of the sealing post 7 is equal to the depth of the vent hole 2.

[0025] Please see Figure 1-3 An elastic component is provided on the back of the baffle 5, which drives the baffle 5 to move forward and fit against the back of the lintel panel 1. The lateral distance between the two ends of the L-shaped slide groove 4 is equal to the length of the sealing post 7. Thus, when the slide post 6 slides along the lower half of the L-shaped slide groove 4, the sealing post 7 is inserted into the vent hole 2 under the drive of the elastic component, sealing the vent hole 2. Driving components are provided on the back of both sides of the lintel panel 1, which drive the baffle 5 to move up and down.

[0026] Please see Figure 1-2 The elastic component includes two sets of support frames 8 fixedly installed on the back of the lintel panel 1 and distributed left and right. A slide block 9 is provided on the rear side of each support frame 8. L-shaped buckles 10 are fixedly installed at both ends of the slide block 9. The L-shaped buckles 10 are engaged and slid in the middle of the support frame 8. The middle section of the support frame 8 is L-shaped. The slide block 9 and the L-shaped buckles 10 are clamped in the middle of the support frame 8. A side panel 3 is fixedly installed in the middle of the support frame 8, and the L-shaped buckles 10 are attached to the surface of the side panel 3. This allows the slide block 9 to move up and down relative to the lintel panel 1.

[0027] Please see Figure 1-2 Two sets of guide rods 11 are slidably connected through the surface of the slide block 9. The guide rods 11 are fixedly installed on the back of the baffle 5, so that the baffle 5 can move back and forth relative to the slide block 9, and the slide block 9 moves up and down synchronously when the baffle 5 moves up and down. A spring 12 is fixedly installed between the baffle 5 and the slide block 9, and the spring 12 is sleeved on the outside of the guide rods 11. Through the elasticity of the spring 12, the baffle 5 has a tendency to move forward relative to the slide block 9.

[0028] Please see Figure 4The drive assembly includes two sets of rotating shaft seats 13 fixedly installed on the upper and lower sides of the support frame 8. A sprocket 14 is rotatably connected to the end of each rotating shaft seat 13. A chain belt 15 meshes with the outer sides of the two sets of sprockets 14. A fixing plate 16 is fixedly installed on the surface of the L-shaped buckle plate 10, and the fixing plate 16 is fixedly installed on the surface of the chain belt 15. Thus, when the sprocket 14 rotates, it drives the chain belt 15 to move, and through the connecting action of the fixing plate 16, it drives the slide block 9 to slide along the support frame 8. Combined with the connecting action of the guide rod 11, it drives the baffle 5 to move up and down.

[0029] Please see Figure 4 A motor can be connected to the center of the upper sprocket 14 to drive the sprocket 14 to rotate. A rotating wheel 17 is coaxially fixed to the upper sprocket 14, and an annular belt 18 is sleeved on the outside of the rotating wheel 17. Alternatively, by pulling the annular belt 18, the rotating wheel 17 and the upper sprocket 14 can be rotated, thereby driving the slide 9 to rotate, and then driving the baffle 5 to move up and down through the guide rod 11.

[0030] Working principle: The ventilation holes 2 ensure ventilation of the lintel panel 1. When ventilation is not required, manually pulling the ring belt 18 drives the rotating wheel 17 and the upper sprocket 14 to rotate, thereby moving the chain belt 15. With the connection of the fixing plate 16, the assembly of the slide 9 and the L-shaped buckle 10 moves downward along the support frame 8. Through the connection of the guide rod 11, the baffle 5 moves downward.

[0031] As the baffle 5 moves downward, the sliding column 6 slides along the L-shaped groove 4. Under the elastic action of the spring 12, the sealing column 7 is pressed tightly against the back of the lintel 1 and embedded in the vent hole 2 to seal the vent hole 2.

[0032] When ventilation is needed again, manually pull the guide rod 11 backward to pull the sealing post 7 out of the spring 12, then pull the annular belt 18 to drive the rotating wheel 17 to rotate, thereby moving the assembly of the baffle 5 and the sealing post 7 upward. The vent hole 2 is no longer sealed, ensuring normal ventilation of the lintel panel 1.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
