[0029] 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.

[0030] The purpose of this utility model is to provide a curtain wall ventilator to solve the problems existing in the prior art and improve the thermal insulation performance of the curtain wall ventilator.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 5 As shown, this utility model provides a curtain wall ventilator, including a fixing unit, a rotating unit, and an opening and closing mechanism.

[0033] The fixing unit includes a fixing box 1 with an opening on one side, specifically comprising a closed frame 101 and a baffle 102. The closed frame 101 provides structural support, and the baffle 102 is fixedly connected to the closed frame 101 and located on the side of the closed frame 101 away from the opening. The baffle 102 has several air inlets 1021 for introducing outside air to achieve ventilation. To prevent dust and other debris from entering, each air inlet 1021 is equipped with a filter screen 1032. The filter screen 1032 effectively filters dust and debris from the air, preventing them from entering the room, ensuring clean indoor air, reducing dust contamination of the ventilator's internal structure, lowering maintenance costs, and extending the ventilator's service life. The fixing unit is designed for direct installation on the curtain wall, and the air inlets 1021 are directly connected to the air inlets on the curtain wall.

[0034] In the optional solutions of this embodiment, the more preferred solution is that the opening covers the entire area of ​​the top of the fixed box 1, forming an open structure with no obstruction at the top. The edge of the opening coincides with the outer periphery of the top of the fixed box 1. This design increases the ventilation area and improves the ventilation efficiency. It also facilitates the rotation and opening of the panel 2, further optimizing the ventilation performance and operating experience of the ventilator.

[0035] The rotating unit includes a panel 2 and a bracket 3; the panel 2 is rotatably connected to the opening via a rotating shaft 4. Specifically, the panel 2 is rotatably connected to the first side of the opening via the rotating shaft 4. The axial direction of the rotating shaft 4 is the same as the length direction of the first side, so that the panel 2 can rotate around the rotating shaft 4 to realize the opening and closing action.

[0036] One end of the bracket 3 is fixedly connected to the inner side of the panel 2, and the end of the bracket 3 away from the panel 2 is fixedly provided with a sealing plate 5 and detachably connected with a first sealing strip 6. The first sealing strip 6 is in the form of a closed ring. In this embodiment, the first sealing strip 6 is rectangular. In practical applications, the first sealing strip 6 can also be designed as a ring or polygon or other shapes, as long as the first sealing strip 6 forms a closed ring structure with its ends connected. The sealing plate 5 is closer to the panel 2 than the first sealing strip 6, and the sealing plate 5 and the first sealing strip 6 are in close contact. When the panel 2 closes the opening, the first sealing strip 6 can be in close contact with the baffle 102, and all the air inlets 1021 are within the closed ring area formed by the contact between the first sealing strip 6 and the baffle 102, thereby effectively blocking the airflow, reducing the thermal bridge effect, and improving the thermal insulation performance. The sealing plate 5 and the bracket 3 are integrally formed and made of the same material. Both the bracket 3 and the sealing plate 5 are made of non-metallic or insulating materials. The non-metallic materials are PVC, polyurethane, or nylon, which have good thermal insulation performance and durability, effectively reducing heat transfer. Together with the first sealing strip 6, they further enhance the insulation effect of the ventilator, while ensuring that the sealing plate 5 is not easily damaged during long-term use, thus improving the reliability and service life of the ventilator. At the same time, the sealing plate 5 and the first sealing strip 6 are tightly fitted, further enhancing the sealing effect and preventing external noise and dust from entering the room. It is worth noting that in practical applications, the sealing plate 5 can be omitted, and the sealed bottom surface of the bracket 3 can also be used as the sealing plate 5.

[0037] In this embodiment, the detachable connection between the bracket 3 and the first sealing strip 6 is specifically implemented as follows: the end of the bracket 3 away from the panel 2 is provided with a first sealing strip groove corresponding to the first sealing strip 6, and the first sealing strip 6 is engaged with the first sealing strip groove.

[0038] The opening and closing mechanism includes a handle 7, a fixing box 8, a connecting rod 9, a slider 10, a pull plate 11, a locking point 12, and a locking seat 13. The fixing box 8 is fixedly connected to the panel 2, and the side of the fixing box 8 closest to the panel 2 is parallel to the panel 2. The panel 2 has a clearance groove 201 corresponding to the handle 7. One end of the handle 7 is hinged to the fixing box 8, allowing the handle 7 to rotate around the hinge point. The design of the clearance groove 201 allows the handle 7 to be placed flat within the clearance groove 201, preventing the handle 7 from being exposed and improving the flatness and aesthetics of the outer side of the panel 2.

[0039] The slider 10 and the fixed box 8 slide in a first direction. In this embodiment, the first direction is the same as the length direction of the panel 2. One end of the connecting rod 9 is hinged to the handle 7 and the other end is hinged to the slider 10. By rotating the handle 7, the connecting rod 9 is driven to move, thereby causing the slider 10 to slide in the fixed box 8 along the first direction.

[0040] Pull plate 11 is fixedly connected to slider 10. All locking points 12 are spaced apart on pull plate 11. Locking points 12 are cylindrical. Lock seats 13 correspond one-to-one with locking points 12 and are fixedly connected to fixed box 1. Lock seats 13 are used to limit the corresponding locking points 12. When panel 2 closes the opening and handle 7 is placed flat in clearance groove 201, all lock seats 13 can limit the corresponding locking points 12, realizing the fixed closure of panel 2. When handle 7 is lifted from clearance groove 201, the connecting rod 9 drives slider 10 and pull plate 11 to move, so that all locking points 12 can be offset from the corresponding lock seats 13. At this time, panel 2 can be rotated to open.

[0041] To ensure the stability of the pull plate 11's movement, an extension plate 17 is provided on the side of the panel 2 near the bracket 3. The extension plate 17 is perpendicular to the panel 2 and is integrally formed with the panel 2. A sliding groove 301 is provided on the extension plate 17 corresponding to the pull plate 11. The length direction of the sliding groove 301 is the same as the first direction. The pull plate 11 and the sliding groove 301 slide in the first direction, so that the pull plate 11 will not deviate during movement. This provides guidance and support for the sliding of the pull plate 11, making the transmission of the opening and closing mechanism more stable and reliable, ensuring that the locking point 12 and the locking seat 13 can accurately cooperate, and improving the accuracy and stability of the ventilator's locking and opening operations. It is worth noting that the reason why the sliding groove 301 is set on the extension plate 17 instead of the bracket 3 is that the bracket 3 is made of non-metallic materials or insulation materials, which have insufficient support strength, while the extension plate 17 and the panel 2 are integrally formed and both are made of metal materials, which have sufficient support strength.

[0042] Furthermore, the curtain wall ventilator in this embodiment also includes two hinge assemblies, with the bracket 3 located between the two hinge assemblies. Each hinge assembly includes a hinge rod 14, a first connecting seat 15 fixed to the bottom of the closed frame 101, and a second connecting seat 16 fixed to the bracket 3. A fixing rod 1601 is fixed on the second connecting seat 16. One end of the hinge rod 14 is hinged to the first connecting seat 15, and a long groove 1401 is provided on the hinge rod 14. The fixing rod 1601 slides in conjunction with the long groove 1401. By providing a certain amount of damping between the fixing rod 1601 and the long groove 1401, the panel 2 can be maintained at any angle when opened or closed, making it convenient to use. The hinge assembly plays an auxiliary support and guiding role during the opening and closing of the panel 2, ensuring the smoothness of the opening and closing action of the panel 2.

[0043] When the curtain wall ventilator of this embodiment is in use, if ventilation is needed, lift the handle 7 to disengage the locking point 12 from the locking seat 13, rotate the panel 2, and allow outside air to enter the room through the air inlet 1021 and the filter screen 1032; if ventilation is not needed, rotate the panel 2 to close the opening, place the handle 7 flat in the clearance groove 201, so that the locking point 12 and the locking seat 13 cooperate to limit the position, and the first sealing strip 6 is tightly attached to the baffle 102, effectively blocking the airflow, reducing the thermal bridge effect, and improving the thermal insulation performance.

[0044] In this embodiment, the curtain wall ventilator can be installed vertically in the column slot or horizontally in the beam slot. In this embodiment, the air inlet 1021 on the baffle 102 is directly connected to the air duct in the curtain wall. A second sealing strip 18 is detachably connected to the side of the baffle 102 away from the closed frame 101. The second sealing strip 18 is used to enhance the sealing between the fixing box 1 and the curtain wall. The second sealing strip 18 is in the shape of a closed ring. A second sealing strip groove is provided on the side of the baffle 102 away from the closed frame 101 corresponding to the second sealing strip 18. The second sealing strip 18 is engaged with the second sealing strip groove.

[0045] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
