[0029] The present invention will be further described below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0030] See also Figures 1-6 This embodiment discloses a ventilation and anti-peep shutter, including a frame 1, a plurality of movable blades 2, a plurality of fixed blades 3 and an opening and closing control component.

[0031] In this embodiment, the ends of the multiple movable blades 2 are rotatably connected to the inner sides of the frame 1, and a fixed blade 3 is provided between two adjacent movable blades 2; one end of each movable blade 2 is connected to the opening and closing control component, which controls the synchronous rotation of each movable blade 2. Each movable blade 2 is Z-shaped, including two extensions 201 and a connecting portion 202; the connecting portion 202 is located between the two extensions 201, and the two extensions 201 are symmetrical about the center; when the multiple movable blades 2 are closed, a receiving cavity 6 for accommodating the fixed blade 3 is formed between two adjacent movable blades 2. The vertical shielding distance of the fixed blade 3 is greater than or equal to the vertical spacing between the closest points of the two adjacent movable blades 2 when they are open, and in this embodiment, the fixed blade 3 is separated from the two movable blades 2 and the two do not contact each other.

[0032] Furthermore, arc segments 203 are provided on both sides of the connecting portion 202; the arc segments 203 are located between the connecting portion 202 and the extending portion 201. By providing the arc segments 203, in the open state, Figure 2 As shown, the path of airflow entering the room is smoother, which can help reduce the blocking effect on the air and improve the ventilation effect compared to the straight design.

[0033] Furthermore, a first bevel 204 is provided at the end of the extension portion 201; when the movable blade 2 is in the open state, the first bevel 204 is in a horizontal position. A second bevel 205 is provided at both outer corners of the connection portion 202; when the movable blade 2 is in the open state, the second bevel 205 is in a horizontal position. Rubber pads for sealing and sound insulation are provided at the first bevel 204 and the second bevel 205. Specifically, rubber pads made of silicone or other soft rubber materials can be provided at the first bevel 204 and the second bevel 205 of the movable blade 2, so that the sealing and sound insulation performance between two adjacent movable blades 2 in the closed state is better. At the same time, see Figure 2 and Figure 3 The arrangement of the first oblique opening 204 and the second oblique opening 205 makes the matching degree of the upper and lower adjacent movable blades 2 higher in the closed state.

[0034] The fixed blade 3 of this embodiment includes a fixed plate 301 and two guide plates 302. The fixed plate 301 is tilted, and the two ends of the fixed plate 301 face the arc sections 203 of the two adjacent movable blades 2. The two guide plates 302 are parallel to each other and are respectively connected to the two ends of the fixed plate 301. Figure 1 and Figure 2 As shown, the fixed blades 3 in this embodiment also have a Z-shaped structure, with a centrally symmetrical structure. The fixed plate 301 in this embodiment is designed to be inclined, which can reduce the impact on airflow while ensuring that the field of view is blocked. At the same time, combined with the arrangement of two guide plates 302, it has a certain guiding effect on the flow of air, which is conducive to further improving the air circulation effect.

[0035] Further, see Figure 2 When the movable blade 2 is open, the upper and lower ends of the fixed blade 3 and the lower end of the movable blade 2 located on the upper side and the upper end of the movable blade 2 located on the lower side have a certain overlapping distance in the horizontal direction, such as Figure 2 The visual analysis line 8 is designed so that the line of sight cannot penetrate through it, thus ensuring the anti-peeping effect. Figure 2 From the airflow analysis line 7, it can be found that the arc segment 203 structure in the movable blade 2 combined with the tilt characteristics of the fixed blade 3 forms a smooth channel space between the two movable blades 2, making the air flow smoother. At the same time, the space that the air can pass through is also very considerable.

[0036] In this embodiment, the movable blades 2 at the top and bottom of the frame 1 are both connected to privacy shields 4. Privacy shields 4 are attached to the side of the frame 1 that's closest to the movable blades 2 when they're open. Fixed flaps 5 are located at both the top and bottom of the frame 1. When the movable blades 2 are open, the privacy shields 4 and fixed flaps 5 partially overlap horizontally to prevent peek-a-boo.

[0037] Furthermore, a first curved surface 501 is provided on the side of the fixed baffle 5 proximal to the movable blade 2, and a second curved surface 401 is provided on the corresponding portion of the privacy protection component 4 and the fixed baffle 5. The arrangement of the first curved surface 501 and the second curved surface 401 prevents collision and interference between the movable blade 2 and the fixed baffle 5 during the opening and closing rotational movements. At the same time, the highest point of the raised fixed baffle 5 ensures privacy protection when in the open state, resulting in a simple structure and ingenious design.

[0038] The frame 1 of this embodiment can be configured as a rectangle, a circle or other shapes, and the present invention is not limited to one shape. Preferably, the frame 1 of this embodiment adopts a rectangular structure.

[0039] For details regarding the opening and closing control assembly of this embodiment, please refer to the prior art. In this embodiment, each end of the movable blade 2 is provided with a rotating shaft 9, which is rotatably connected to the frame 1. This rotating shaft 9 can also be used to connect to components of the opening and closing control assembly, thereby achieving synchronous rotation of multiple movable blades 2. Of course, the opening and closing control assembly of this embodiment can be controlled manually or electrically.

[0040] The movable blades 2, fixed blades 3 and other components of this embodiment can be made of hard, corrosion-resistant and heat-resistant metals, such as aluminum alloy, stainless steel, or ABS plastic.

[0041] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
