Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] A specific embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a natural ventilator for doors, windows and curtain walls is disclosed, including an outer frame 1 and a rotating structure 2.

[0029] The outer frame 1 is a rectangular frame, including a first border 101 and a second border 102.

[0030] The first border 101 is composed of two first corner frames 1011, and the second border 102 is composed of two second corner frames 1021. The first border 101 and the second border 102 are spaced apart.

[0031] Multiple end cap grooves 10211 are provided along the length direction between the two second corner frames 1021 of the second frame 102. The end cap grooves 10211 are circular grooves used to connect the rotating structure 2. Exemplarily, this embodiment provides three rotating structures 2, and correspondingly, three end cap grooves 10211 are provided between the two second corner frames 1021.

[0032] Furthermore, the first frame 101 also includes a first sealing strip 1012, and the second frame 102 also includes a second sealing strip 1022. The first sealing strip 1012 is disposed between the two first corner frames 1011 in the first frame 101 and extends along the length direction of the first frame 101; the second sealing strip 1022 is disposed between the two second corner frames 1021 in the second frame 102 and extends along the length direction of the second frame 102. The first corner frames 1011, the second corner frames 1021, the first sealing strip 1012, and the second sealing strip 1022 are thermally broken insulation materials.

[0033] Furthermore, a rotating shaft 10221 is provided at the position of the second sealing strip 1022 corresponding to the axis of the end cover groove 10211.

[0034] Furthermore, a panel 103 is provided on the end face formed by the first frame 101 and the second frame 102. The panel 103 is hollowed out and is used for decoration and dust protection.

[0035] The rotating structure 2 includes two crescent-shaped plates 202 and an end cap 201. The end cap 201 is embedded in the end cap groove 10211 of the second frame 102. Specifically, the radius of the end cap 201 is slightly smaller than the inner diameter of the end cap groove 10211. The rotating shaft 10221 passes through the center of the end cap 201, and the end cap 201 can rotate around the rotating shaft 10221 in the end cap groove 10211.

[0036] The end cap 201 has a first arc-shaped groove 2011 on the upper and lower sides. The length direction of the crescent-shaped plate 202 is the same as the length direction of the first frame 101. The two ends of the crescent-shaped plate 202 can be embedded in the first arc-shaped groove 2011 of the end cap 201 in the two second frames 102 and rotate with the rotation of the end cap 201.

[0037] The crescent-shaped plate 202 includes a flat portion and an arc-shaped portion. It should be noted that, in order for the upper and lower crescent-shaped plates 202 to be fully closed when the ventilator is closed, the radius of the edge arc of the arc-shaped portion is the same as the radius of the end cap 201, and the width of the flat portion is the same as the radius of the end cap 201.

[0038] When the ventilator is fully open, the flat portions of the upper and lower crescent-shaped plates 202 are parallel to the first frame 101, with the largest gap in between, thus providing the maximum ventilation volume. As the end cap 201 rotates around the pivot 10221 located at its axis, the upper and lower crescent-shaped plates 202 rotate and slowly tilt, forming an angle between the planar portions of the upper and lower crescent-shaped plates 202 and the first frame 101. The gap formed between the upper and lower crescent-shaped plates 202 then decreases, and the ventilation volume gradually decreases. When the ventilator is completely closed, the crescent-shaped plates 202 rotate 90°, and the planar portions of the upper and lower crescent-shaped plates 202 are perpendicular to the first frame 101. The lower edge of the upper crescent-shaped plate 202 and the upper edge of the lower crescent-shaped plate 202 connect, and the gap is completely blocked. At this time, the vent is closed.

[0039] Furthermore, the ventilator is provided with at least one rotating structure 2. When a rotating structure 2 is provided, it has one end cover 201; multiple rotating structures 2 have multiple end covers 201. In order to enable the multiple end covers 201 to rotate synchronously, a connecting rod 203 is provided in the middle of the multiple end covers 201, and the length direction of the connecting rod 203 is perpendicular to the axial direction of the end cover 201.

[0040] Furthermore, for ease of operation, such as Figure 3 As shown, a handle 204 is provided on the circumferential edge of the middle end cover 201. One of the second frame frames 102 has a handle groove 1023 on the side where the panel 103 is installed, and the handle 204 can extend out of the handle groove 1023. When the end cover 201 needs to be rotated, the ventilator can be turned on and off by rotating the handle 204, and the ventilation volume can be controlled by rotating the handle 204 at different angles.

[0041] Furthermore, a partition structure 3 is provided between adjacent rotating structures 2. The partition structure 3 is made of thermally broken material. Both ends of the partition structure 3 are fixed to the second frame 102. The upper and lower parts of the partition structure 3 are symmetrical second arc-shaped grooves 301, the radius of which is slightly larger than the radius of the crescent-shaped plate 202. These grooves are used to accommodate the crescent-shaped plate 202 of the rotating structure 2 and allow the crescent-shaped plate 202 to rotate within the second arc-shaped groove 301.

[0042] Compared with the prior art, the ventilator in this embodiment has a rotary structure. By rotating the handle 204, the crescent-shaped plate 202 rotates at different angles, and gaps of different sizes are formed between the two crescent-shaped plates 202 to adjust the required ventilation volume. It does not require electricity, has a simple structure, is easy to operate, and is energy-saving and noise-reducing. Moreover, the outer contour does not change before and after opening, does not protrude from the wall, and ensures safety. It can be used in combination with doors, windows, various curtain walls, and walls, and is easy to install.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
