[0002] High-end office buildings almost always use a single glass curtain wall facade, and most offices are designed as enclosed window spaces. As a result, the windows in high-end office buildings have lost their traditional function of ventilation, so curtain wall ventilators are needed for ventilation.

[0003] Chinese patent document CN207177000U discloses a curtain wall ventilator, comprising: an aluminum alloy ventilator base, which is mounted on an aluminum alloy horizontal beam of the curtain wall, the horizontal beam being connected to aluminum alloy columns; an aluminum alloy ventilator cover plate installed on the upper part of the base; the front end of the cover plate being connected to the base via an anti-fall-off axial rotation switch; and the rear end of the cover plate having an axial rotation aluminum alloy buckle plate. Through this design, the curtain wall ventilator of this invention has a simple structure, a beautiful and three-dimensional appearance, and can operate normally for ventilation in rainy and windy weather, improving the effect of preventing rainwater penetration. It is highly versatile and suitable for installation with various curtain walls.

[0004] The aforementioned curtain wall ventilators can only be used in two states: open and closed. This makes it difficult to control the ventilation volume independently, which is insufficient to meet the diverse needs of users and reduces the usability and practicality of the device. Utility Model Content

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a louvered curtain wall ventilator, including a base box 1 and an air volume regulating mechanism 4. The air volume regulating mechanism 4 is disposed inside the base box 1 and includes an annular partition 401, a square rod 406, a large helical gear 407, and an air damper 408. The annular partition 401 is fixedly installed on one inner wall of the base box 1, and the square rod 406 is rotatably installed on both inner walls of the annular partition 401. One end of the square rod 406 extends into the interior of the base box 1 and is fixedly installed. The bottom box 1 is equipped with a damper plate 408, one side of which is rotatably connected to the inner wall of the other side of the bottom box 1. The outer wall of the square rod 406 is fixedly connected to the inside of the large helical gear 407. A rectangular opening is provided on the front side of the annular partition plate 401, and a plastic plate 5 is inlaid inside the rectangular opening. A main panel 2 is fixedly installed on the front side of the bottom box 1, and a vent 3 is provided on the front side of the main panel 2. A baffle plate 9 is fixedly installed on the front side of the bottom box 1. Fixed support plates 8 are fixedly installed on the top and bottom inner sides of the bottom box 1.

[0022] Secondly, the air volume adjustment mechanism 4 also includes a gear support plate 402, a rotating rod 403, a small helical gear 404, and a switch knob 405. The gear support plate 402 is fixedly installed on the bottom and top inner sides of the base box 1. The front side of the gear support plate 402 is rotatably connected to one end of the rotating rod 403. The outer wall of the rotating rod 403 is fixedly connected to the inside of the small helical gear 404. The small helical gear 404 and the large helical gear 407 mesh with each other. The other end of the rotating rod 403 passes through the plastic plate 5 and is fixedly installed with the switch knob 405. Rotating the switch knob 405 can adjust the angle of the damper plate 408, which facilitates independent control of the ventilation volume of the device, meets various user needs, is simple and easy to operate, and improves the usability and practicality of the device.

[0023] Furthermore, a protective cover 7 is hinged to the front side of the plastic plate 5, and a perforated clip 6 is fixedly installed on the front side of the plastic plate 5. The rear side of the protective cover 7 is connected to the interior of the perforated clip 6 to hide the switch knob 405 and prevent others from accidentally touching it.

[0024] Working principle: When using this device, it is installed on the curtain wall through the reserved gap. Outside air is ventilated through the ventilation hole 3. When the ventilation volume needs to be adjusted, the protective cover 7 is flipped to separate it from the perforated locking block 6, exposing the switch knob 405. Turning the switch knob 405 causes the rotating rod 403 to rotate on the gear support plate 402, which drives the small helical gear 404 to rotate. Through the meshing transmission of the small helical gear 404 and the large helical gear 407, the square rod 406 is driven to rotate, which in turn drives the damper plate 408 to rotate. The angle of the damper plate 408 is adjusted, and the obstruction range of the damper plate 408 in the base box 1 is adjusted, thereby controlling the ventilation volume of the device.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
