Technical Field

[0001] The utility model relates to the field of curtain wall ventilation, in particular to a curtain wall structure with automatic air exchange. Background Art

[0002] In order to improve the energy conservation and environmental protection effect of buildings, the existing curtain wall structures are usually set as double-layer curtain wall structures, so as to achieve heat preservation or ventilation inside the buildings, thereby reducing the energy consumption of heating or cooling. However, when the external air enters between the inner and outer curtain walls through the outer curtain wall and finally enters the room, it is very easy to bring in impurities such as dust, which affects the air cleanliness in the room and the physical health of the indoor residents. The existing method is generally to set a filtering component at the air inlet of the outer curtain wall to effectively filter the entering air. However, the filtering component on the outer curtain wall is in contact with the external air all year round, and even when there is no ventilation, the impurities in the external air are very easy to adhere to the filtering component, resulting in easy blockage of the filtering component. Moreover, the filtering component on the outer curtain wall is not easy to clean, resulting in very difficult replacement and cleaning of the filtering component, affecting the filtering effect of the air entering the room and the actual use experience. Content of the Utility Model

[0003] The purpose of the utility model is to provide a curtain wall structure with automatic air exchange, which can solve the technical problem that the filtering component on the outer curtain wall is easily blocked and affects the filtering effect, so that the filtering component is only put into use during ventilation, reducing the contact time between the filtering component and the external air, reducing the probability of blockage, reducing the frequency of replacement and cleaning, and improving the convenience of actual use.

[0004] To achieve the above object, the utility model is realized by the following technical solutions:

A baffle is slidably connected vertically on the side of the outer curtain wall panel facing the air channel. The baffle is used to control the opening and closing of the air inlet. A first filter plate cooperating with the air inlet is rotatably connected to the bottom of the air channel. A return spring is arranged between the first filter plate and the bottom of the air channel. A connecting component is arranged between the baffle and the first filter plate. When the baffle slides upward, the first filter plate is driven by the connecting component to rotate towards the air inlet. A second filter plate is slidably connected vertically in the air exchange pipe. A positioning column cooperating with the second filter plate is arranged on the air exchange pipe.

[0006] Further, the connecting component is a connecting rope. One end of the connecting rope is connected to the baffle, and the other end of the connecting rope is connected to the top of the first filter plate.

[0020] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0021] Refer to Figure 1 and Figure 2, the utility model relates to a curtain wall structure with automatic ventilation. The main structure includes an inner curtain wall panel 1 and an outer curtain wall panel 2. An air passage 3 is formed between the inner curtain wall panel 1 and the outer curtain wall panel 2. Such a structure enables an air buffer layer to be formed in the air passage 3, so that the air in the air passage 3 can flow automatically by using the greenhouse effect and the chimney effect in summer, reducing the temperature on the side of the inner curtain wall panel 1 and the power consumption of indoor refrigeration. In winter, the temperature in the air passage 3 is increased by using solar radiation, so that the temperature on the side of the inner curtain wall panel 1 is increased, thereby reducing the power consumption of indoor heating and making the building more energy-saving and environment-friendly. An air inlet 4 and an air outlet 5 are respectively arranged at the bottom and the top of the outer curtain wall panel 2. The outside air enters the air passage 3 from the air inlet 4 and is discharged from the air outlet 5. An air exchange pipe 6 is arranged on the inner curtain wall panel 1. The arrangement of the air exchange pipe 6 enables the air in the air passage 3 to communicate with the indoor air. A baffle 7 is slidably connected vertically on the side of the outer curtain wall panel 2 facing the air passage 3. The baffle 7 is used to control the opening and closing of the air inlet 4. The baffle 7 can slide downwards to close the air inlet 4 when heat preservation of the building is required, and slide upwards to open it when ventilation and cooling are required in summer. A first filter plate 8 used in cooperation with the air inlet 4 is rotatably connected to the bottom of the air passage 3 through a pin shaft or a hinge. The first filter plate 8 is used to filter the external air passing through. Any material with a filtering effect available on the existing market can be adopted as the specific material. A return spring 9, preferably a torsion spring, is arranged between the first filter plate 8 and the bottom of the air passage 3. The arrangement of the return spring 9 can keep the first filter plate 8 in a state located at the bottom of the air passage 3. A connecting component is arranged between the baffle 7 and the first filter plate 8. When the baffle 7 slides upwards, the first filter plate 8 is driven by the connecting component to rotate towards the air inlet 4, stretching the return spring 9. In such a structure, when ventilation is not required, the baffle 7 is located at the bottom to close the air inlet 4, and the first filter plate 8 is kept at the bottom of the air passage 3 under the action of the return spring 9 and does not contact the external air, thereby reducing the possibility of blockage. When ventilation is required, the baffle 7 slides upwards to open the air inlet 4. During this process, the first filter plate 8 is driven by the connecting component to rotate towards the air inlet 4 until it fits at the air inlet 4, so as to effectively filter the external air passing through the air inlet 4, thereby achieving the filtering effect of the air. After ventilation, the baffle 7 slides downwards to close the air inlet 4 again. Under the action of the return spring 9, the first filter plate 8 rotates reversely to reset, so that the first filter plate 8 only contacts the external air when ventilation is required, reducing the contact time with the external air, reducing the possibility of blockage, reducing the frequency of replacement and cleaning, and improving the actual use experience. A second filter plate 10 is slidably connected vertically in the air exchange pipe 6. The second filter plate 10 is generally located indoors and its size is adapted to the inner diameter of the air exchange pipe 6. It can enter and exit the air exchange pipe 6 by sliding up and down, and filter the air passing through the air exchange pipe 6 after entering.It is convenient to replace it after sliding out. The replacement air pipe 6 is provided with positioning posts 11 for cooperating with the second filter plate 10. The positioning posts 11 are used to position and fix the second filter plate 10 during use to ensure accurate filtering effect.

[0022] Preferably, the connecting component is a connecting rope 12. One end of the connecting rope 12 is connected to the baffle 7 by bolts or directly tied to the baffle 7. The other end of the connecting rope 12 is connected to the top of the first filter plate 8. Such a structure can smoothly drive the first filter plate 8 to rotate when the baffle 7 slides up and down. And after the baffle 7 slides up a sufficient distance, the first filter plate 8 can accurately fit at the air inlet 4 to ensure accurate filtering of the external air passing through the air inlet 4.

[0023] Preferably, referring to Figure 3 the thickness of the first filter plate 8 is greater than that of the baffle 7. Such a structure enables the connecting rope 12 not to need to rotate to the vertical state to make one side of the first filter plate 8 fit at the air inlet 4. Thus, the inclined connecting rope 12 can better block the first filter plate 8 at the air inlet 4, improving the tightness of the connection between the first filter plate 8 and the air inlet 4 and ensuring the filtering effect.

[0024] Preferably, the first filter plate 8 is provided with a plurality of filter holes 13. The filter holes 13 are inclined. Specifically, the height of one side of the filter holes 13 facing the air inlet 4 is lower. Such a structure enables rainwater to be blocked to a certain extent at the inclined filter holes 13 when rainwater enters the filter holes 13 in rainy and snowy weather, reducing the possibility of rainwater entering the air passage 3 or the room.

[0025] Preferably, referring to Figure 4 the air passage 3 is symmetrically provided with guide grooves 14. Specifically, the cross-section of the guide grooves 14 is L-shaped. It is fixed to the inner wall of the air passage 3 by welding or bolts. The two sides of the baffle 7 are symmetrically welded or bolted with sliders 15 slidably connected to the guide grooves 14. The guide grooves 14 are provided with parallel screw rods 16 and guide rods 17. The screw rod 16 penetrates through one of the sliders 15 and is threadedly connected thereto. The guide rod 17 penetrates through the other slider 15 and is slidably connected thereto. The screw rod 16 is driven to rotate by a motor. When the screw rod 16 rotates, the sliders 15 and the baffle 7 slide up and down along the guide posts under the action of threaded connection, making the control of the position of the baffle 7 more accurate and convenient.

[0026] Preferably, the positioning post 11 is threadedly connected to the bottom of the air exchange pipe 6. A plurality of positioning holes 18 that are movably inserted into the positioning post 11 are provided at the bottom of the second filter plate 10. By rotating the positioning post 11, it can enter and exit the positioning holes 18 under the action of the threaded connection, so as to ensure the firmness of the position of the second filter plate 10 during use. When disassembling and replacing, only need to rotate the positioning post 11 in the reverse direction to make it rotate out of the positioning holes 18, and then the second filter plate 10 can be conveniently slid out, making the disassembly and replacement more convenient.

[0027] Working principle: In the present utility model, an air inlet 4 and an air outlet 5 are respectively provided at the bottom and the top of the outer curtain wall panel 2. A baffle 7 for controlling the opening and closing of the air inlet 4 is slidably connected vertically along the side of the outer curtain wall panel 2 facing the air passage 3. A first filter plate 8 for cooperating with the air inlet 4 is rotatably provided at the bottom of the air passage 3. In such a structure, when ventilation is not required, the baffle 7 slides downward to close the air inlet 4, and the first filter plate 8 is kept at the bottom of the air passage 3 under the action of the reset assembly. When ventilation is required, the baffle 7 slides upward, and under the drive of the connection assembly, the first filter plate 8 is urged to rotate towards the air inlet 4, so that the first filter plate 8 only plays a filtering effect when the air inlet 4 is opened, ensuring that the first filter plate 8 only contacts the outside air when ventilating, thereby greatly reducing the contact time of the first filter plate 8 with the outside air, reducing the possibility of blockage, reducing the frequency of replacement and cleaning, and improving the actual use experience; an air exchange pipe 6 is provided on the inner curtain wall panel 1. A second filter plate 10 is slidably connected vertically in the air exchange pipe 6. A positioning post 11 for cooperating with the second filter plate 10 is provided on the air exchange pipe 6. In such a structure, when the air in the air passage 3 enters the room through the air exchange pipe 6 during ventilation and air exchange, the second filter plate 10 is used to filter the air again. When the air intake volume of the second filter plate 10 decreases, the restriction of the positioning post 11 on it can be released, so as to realize the convenient replacement of the second filter plate 10 that is easily accessible to the residents, further ensuring the cleanliness of the indoor air during ventilation.
