Description

Technical Field

[0001] This utility model relates to the field of louver technology, and in particular to a breathable and moisture-proof PVC louver. Background Technology

[0002] These breathable and moisture-proof PVC blinds are manufactured using modified PVC material and a special process, combining durability, functionality, and aesthetics. By optimizing the material formula, heat-resistant stabilizers, moisture-proofing agents, and reinforcing fillers are added to the PVC base material, making it resistant to deformation in high-temperature environments and preventing mold or corrosion even after prolonged exposure to humid air. The slats feature a wavy or curved structure, combined with a microporous ventilation design, ensuring airflow while effectively blocking the view, thus balancing privacy and ventilation needs.

[0003] Traditional flat louvers have revealed problems in actual use, such as low ventilation efficiency, poor drainage, easy water accumulation and corrosion, and difficulty in drying in humid environments, which affect their service life and functionality. Utility Model Content

[0004] The purpose of this utility model is to provide a breathable and moisture-proof PVC louver. The wavy louver can increase air circulation and improve natural ventilation efficiency, and it has good air permeability. The water channel on the wavy louver can make water droplets flow quickly and fall from the circular water hole, which has good water guiding properties.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a breathable and moisture-proof PVC louver, including a window frame, and further comprising:

[0006] A ventilation mechanism is installed inside the window frame. The ventilation mechanism includes strip mounting plates that are fixedly installed on the inner walls of the left and right sides of the window frame, respectively. Several rotating shafts are rotatably mounted on the two strip mounting plates, and wavy window leaf is fixedly sleeved on each of the several rotating shafts.

[0007] A closing mechanism is provided inside the window frame. The closing mechanism includes a rectangular box fixedly installed on the inner left wall of the window frame. A limiting groove is opened through the rectangular box. A T-shaped toothed plate is slidably installed in the limiting groove. The top end of the T-shaped toothed plate extends slidably outside the limiting groove. An L-shaped connecting plate is hinged to the left side of the T-shaped toothed plate. A strip plate is hinged to the top end of the L-shaped connecting plate.

[0008] Preferably, a plurality of fixed plates are hinged to the right side of the strip plate, and the plurality of fixed plates are respectively fixedly connected to a plurality of rotating shafts. A rotating shaft is rotatably installed inside the rectangular box, and a gear is fixedly sleeved on the rotating shaft. The gear meshes with a T-shaped toothed plate.

[0009] Preferably, the right end of the rotating shaft extends rotatably outside the rectangular box, a strip-shaped fixing plate is fixedly installed on the right end of the rotating shaft, and a hollow rotating tube is rotatably installed on the right side of the strip-shaped fixing plate.

[0010] Preferably, a plurality of water channels are provided on each of the plurality of wavy window leafes, and two circular water holes are provided in each of the plurality of water channels.

[0011] Preferably, a streamlined arc block is fixedly installed on the bottom inner wall of the window frame, and a number of arc grooves are opened on the top of the streamlined arc block, and an irregularly shaped drainage groove is opened on the bottom inner wall of the window frame.

[0012] The beneficial effects of this utility model are:

[0013] 1. Under normal circumstances, adjust the wavy window slats to the state shown in the picture. When the wind blows in from outside the window, it will pass through the wavy window slats. The wavy window slats can increase air circulation and improve natural ventilation efficiency, and they have good air permeability. When water is accidentally splashed onto the wavy window slats, the water droplets will flow quickly under the action of the water channel and fall continuously from the circular water outlet until they fall onto the streamlined arc block. Under the limiting action of the arc channel, they will be separated from the window frame by the irregular drainage channel or directly discharged outside the window. It can also prevent rainwater from accumulating on the device and causing corrosion on rainy days. Under the condition of high ventilation, the wavy window slats will also dry quickly, extending the service life of the device.

[0014] 2. When the opening and closing size of the louvers needs to be adjusted, the hollow rotating tube is rotated, which drives the strip fixing plate to rotate. The strip fixing plate drives the rotating shaft to rotate, which drives the gear to rotate. The gear drives the T-shaped toothed plate to rise and fall, which drives the L-shaped connecting plate to rise and fall. The L-shaped connecting plate drives the strip plate to rise and fall, which drives several rotating shafts to adjust. The rotating shafts drive several wavy louvers to adjust their angles simultaneously, thereby adjusting the degree of closure of the louvers. Adjusting the opening and closing size of the louvers also allows the water in the drainage channel to quickly escape, better protecting the wavy louvers. Attached Figure Description

The wavy window slats 102 can increase air circulation and improve natural ventilation efficiency, and it has good air permeability. When water is accidentally splashed onto the wavy window slats 102, the water droplets will flow quickly under the action of the water channel 103 and fall continuously from the circular water outlet 104 until they fall onto the streamlined arc block 105. Under the limiting action of the arc groove 106, they will detach from the window frame 1 through the irregular drainage channel 107 or be discharged directly outside the window. It can also prevent rainwater from accumulating on the device and causing corrosion on rainy days. Under the condition of high ventilation, the wavy window slats 102 will also dry quickly, extending the service life of the device.

Under the limiting action of the arc groove 106, they will be separated from the window frame 1 from the irregular drainage channel 107 or directly discharged to the outside of the window. It can also prevent rainwater from accumulating on the device and causing corrosion on rainy days. Under the condition of high ventilation, the wavy window slats 102 will also dry quickly, extending the service life of the device.
