Therefore, a new device that can open and close the vents is provided.

[0031] Embodiment 1:

[0032] like Figures 1 to 5 The utility model provides a curtain wall unit with a ventilation device.

[0033] Specifically, by Figure 1-Figure 5 A curtain wall unit with a ventilation device is provided, comprising a curtain wall unit body 1, a fixed frame 3 is fixedly connected between two curtain wall unit bodies 1, a plurality of ventilation holes 9 are opened on the outer wall of the fixed frame 3, an adjusting component 2 is arranged inside the fixed frame 3, the adjusting component 2 comprises a connecting rod 201 rotatably connected to the fixed frame 3, one end of the connecting rod 201 located inside the fixed frame 3 is fixedly connected to a worm 202, the inner wall of the fixed frame 3 is rotatably connected to a bidirectional screw rod 203, the outer wall of the bidirectional screw rod 203 is threadedly connected to two wind shields 204, and the outer wall of the bidirectional screw rod 203 is fixedly connected to a worm wheel 205 meshingly connected to the worm 202.

[0034] The fixed frame 3 is installed at the connection between multiple curtain wall unit bodies 1, and the fixed frame 3 realizes ventilation through multiple ventilation holes 9. The fixed frame 3 is located in the interior of the building. When the ventilation needs to be closed or opened, the connecting rod 201 is twisted to drive the worm 202 in the fixed frame 3 to rotate, and the worm 202 drives the worm wheel 205 to rotate. When the worm wheel 205 rotates, it will drive the bidirectional screw rod 203 to rotate. The rotating bidirectional screw rod 203 will make the two wind shields 204 slide along the outer wall of the bidirectional screw rod 203. Adjusting the rotation direction of the bidirectional screw rod 203 can make the two wind shields 204 move toward or away from each other. When the wind shield 204 moves to the position of the ventilation hole 9 and fits with the ventilation hole 9, the ventilation can be closed. When the wind shield 204 is away from the ventilation hole 9, the ventilation can be opened. The adjustment component 2 is located inside the fixed frame 3, so it will not affect the aesthetics of the curtain wall unit body 1, and does not require any driving device, which also reduces energy consumption.

[0035] Further:

[0036] like Figure 3-Figure 4 It is shown that one end of the connecting rod 201 extending to the outside of the fixing frame 3 is fixedly connected with a knob 10 . The knob 10 is located outside the fixing frame 3 , and the knob 10 does not contact the fixing frame 3 .

[0037] The connection rod 201 can be driven to rotate by turning the knob 10 . The knob 10 can provide gripping force, so that the user can turn the knob 10 more easily. The knob 10 does not contact the fixing frame 3 , so it is convenient to hold the knob 10 .

[0038] Further:

[0039] like Figure 2-Figure 5 It is shown that both ends of the bidirectional screw rod 203 are in contact with the ventilation hole 9 , the worm wheel 205 and the worm 202 are both located between two wind shield plates 204 , and the wind shield plates 204 are slidably connected to the fixed frame 3 .

[0040] The bidirectional screw rod 203 is close to the ventilation hole 9, which facilitates the wind shield plate 204 to move to the position of the ventilation hole 9 to close and open the ventilation hole 9. The wind shield plate 204 is slidably connected to the fixed frame 3, which facilitates the wind shield plate 204 to slide inside the fixed frame 3.

[0041] Further:

[0042] like Figure 2 and Figure 5 It is shown that the inner wall of the fixed frame 3 is fixedly connected with a plurality of sliding rods 11 , the wind shield 204 is slidably connected with the outer wall of the sliding rod 11 , and the bottom of the wind shield 204 does not contact with the inner bottom wall of the fixed frame 3 .

[0043] The windshield plate 204 slides along the outer wall of the slide bar 11 while sliding along the bidirectional screw rod 203. The slide bar 11 enables the windshield plate 204 to maintain horizontal movement, preventing the windshield plate 204 from deflecting during movement, and the slide bar 11 enables the windshield plate 204 to move more stably.

[0044] Embodiment 2:

[0045] Further:

[0046] like Figure 1 and Figure 3 It is given that the outer wall of the fixed frame 3 is fixedly connected with a ventilation rack 4, the ventilation rack 4 is provided with a plurality of air inlets 5, the interiors of the ventilation rack 4 and the fixed frame 3 are both set to be hollow, the fixed frame 3 is communicated with the ventilation rack 4, the interior of the ventilation rack 4 is provided with a plurality of filter plates 6, and the filter plates 6 are fitted with the air inlets 5.

[0047] The ventilation rack 4 is located outside the building. External wind enters the interior of the ventilation rack 4 through multiple air inlets 5, and then enters the interior of the fixed frame 3 through the ventilation rack 4. Finally, the wind enters the room from multiple ventilation holes 9. The filter plate 6 blocks impurities in the air and wind to prevent impurities from entering the ventilation rack 4 and causing impurity accumulation.

[0048] Further:

[0049] like Figure 3 It is shown that a plurality of fixing blocks 7 are fixedly installed on the inner wall of the ventilation rack 4, a fixing rod 8 is fixedly connected between the plurality of fixing blocks 7, the filter plate 6 is located between the fixing rod 8 and the air inlet 5, and an outer wall of the fixing rod 8 abuts against an outer wall of the filter plate 6.

[0050] The fixing block 7 fixes the fixing rod 8 and the ventilation frame 4 together, and the fixing rod 8 enables the filter plate 6 to fit with the air inlet 5 to prevent the position of the filter plate 6 from being offset after the wind blows into the air inlet 5. The fixing rod 8 makes the position of the filter plate 6 more stable.

[0051] Working principle:

[0052] The fixed frame 3 is installed at the connection between multiple curtain wall unit bodies 1, and the fixed frame 3 realizes ventilation through multiple ventilation holes 9. The fixed frame 3 is located in the interior of the building. When the ventilation needs to be closed or opened, the connecting rod 201 is twisted to drive the worm 202 in the fixed frame 3 to rotate, and the worm 202 drives the worm wheel 205 to rotate. When the worm wheel 205 rotates, it will drive the bidirectional screw rod 203 to rotate. The rotating bidirectional screw rod 203 will make the two wind shields 204 slide along the outer wall of the bidirectional screw rod 203. Adjusting the rotation direction of the bidirectional screw rod 203 can make the two wind shields 204 move toward or away from each other. When the wind shield 204 moves to the position of the ventilation hole 9 and fits with the ventilation hole 9, the ventilation can be closed. When the wind shield 204 is away from the ventilation hole 9, the ventilation can be opened. The adjustment component 2 is located inside the fixed frame 3, so it will not affect the aesthetics of the curtain wall unit body 1, and does not require any driving device, which also reduces energy consumption.

[0053] The ventilation rack 4 is located outside the building. External wind enters the interior of the ventilation rack 4 through multiple air inlets 5, and then enters the interior of the fixed frame 3 through the ventilation rack 4. Finally, the wind enters the room from multiple ventilation holes 9. The filter plate 6 blocks impurities in the air and wind to prevent impurities from entering the ventilation rack 4 and causing impurity accumulation.

[0054] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
