Description

Technical Field

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

[0002] As people's living standards continue to improve, they are paying more and more attention to the comfort and safety of their home environment. Venetian blinds, as a common window shading and ventilation device, are widely used in various buildings. In daily use, dust and insect intrusion become significant factors affecting the indoor environment. A venetian blind that combines dust and insect prevention can effectively improve indoor air quality, reduce insect bites, and create a healthier and more comfortable living space. Therefore, its research and development are of significant practical importance.

[0003] Traditional Venetian blinds, in terms of their mechanical structure, mainly consist of several parallel slats, a rotating shaft connecting the slats, and an adjustment device for controlling the angle of the slats. The technical principle is that the user manually operates the adjustment device, such as pulling a rope or a rocker arm, to drive the rotating shaft to rotate, thereby changing the tilt angle of the slats to achieve functions such as ventilation, lighting, and sun shading. In terms of dust and insect prevention, some Venetian blinds have simple screens installed at the window frame, but the installation method of these screens is relatively fixed and the structure is simple.

[0004] However, existing venetian blinds have significant drawbacks. In severe weather conditions such as strong winds, traditional venetian blinds cannot automatically adjust the angle of the slats. Users often cannot promptly detect weather changes and manually adjust them, resulting in a large amount of dust being carried by strong winds through the gaps in the slats and entering the room, severely impacting indoor cleanliness. Furthermore, after trapping a large number of insects, the fixed screen becomes extremely inconvenient to clean, requiring considerable time and effort to disassemble the entire screen structure, significantly reducing maintenance efficiency and failing to meet people's demand for convenient and efficient home facilities. Therefore, a dust-proof and insect-proof venetian blind is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dustproof and mosquito-proof louver, which aims to improve the problem that the existing technology cannot adjust the angle of the louvers in time in response to severe weather.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dustproof and mosquito-proof louver includes a window frame, a plurality of window slats are rotatably connected to the inner wall of the window frame, the window slats are arranged in an array inside the window frame, a protective component is provided on the side wall of the window frame, and an adjustment component is provided inside the window frame for adjusting the angle of the window slats.

[0008] The adjustment assembly includes a drive motor, the outer wall of which is fixedly connected to the inside of the window frame. A rocker arm is fixedly connected to the output end of the drive motor. Notches are provided at the bottom and top of the outer wall of the window leaf. The notches are used to reduce gaps when the upper and lower leaf blades are closed. Connecting arms are fixedly connected to the side walls of the window leaf. Linkage arms are provided on the side of the connecting arms. One side wall of the connecting arm is rotatably connected to the side wall of the linkage arm. One side wall of the rocker arm is rotatably connected to the middle position of the side wall of the linkage arm.

[0009] As a further description of the above technical solution:

[0010] The protective component includes an isolation net, the sidewall of which is slidably connected to the sidewall of the window frame, and sensors are fixedly connected to the top and bottom of the outer wall of the isolation net.

[0011] As a further description of the above technical solution:

[0012] The isolation net is equipped with locking posts at each of its four corners, and the outer walls of the locking posts are slidably connected to the window frame and the inside of the isolation net.

[0013] As a further description of the above technical solution:

[0014] Each locking post has multiple ball bearings slidably connected inside, and the ball bearings are distributed in a circumferential shape at the bottom of the locking post. Each locking post has a limit plate fixedly connected to the top of its inner wall.

[0015] As a further description of the above technical solution:

[0016] Each locking post has an inner post that is slidably connected inside. Each inner post has a receiving groove at the bottom of its outer wall, and each inner post has a top post that is fixedly connected to its top.

[0017] As a further description of the above technical solution:

[0018] Multiple auxiliary blocks are fixedly connected to the top of the outer wall of the top column, and multiple protruding blocks are fixedly connected to the bottom of the outer wall of the top column. The auxiliary blocks and protruding blocks are distributed in a circumferential shape on the outer wall of the top column.

[0019] As a further description of the above technical solution:

[0020] Each of the top column sidewalls is provided with a return spring, and the return spring is sleeved on the outer wall of the inner column.

[0021] As a further description of the above technical solution:

[0022] One end of each reset spring is slidably connected to the bottom of the top post, and the other end of each reset spring is fixedly connected to the inside of the locking post.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when the sensor detects a change in weather conditions, it immediately controls the drive motor to rotate, which in turn drives the rocker arm to rotate. The rocker arm then drives the linkage arm to move up and down, and the linkage arm drives the connecting arm to rotate, thereby causing the window slat angle to change. This achieves the effect of automatic opening and closing of the window slats, solving the problem that traditional venetian blinds cannot adjust the window slat angle in time to cope with severe weather, and improving the protective effect and practicality.

[0025] 2. In this utility model, when the isolation net needs to be disassembled and cleaned, the user manually rotates the top column so that the protruding block is aligned with the hole of the limiting plate. The reset spring is released from compression and generates a counter-thrust force, which pushes the top column and inner column to move. The receiving groove slides upward, and the ball slides from the window frame hole into the receiving groove, thus unlocking the isolation net and allowing the user to remove it for cleaning. This solves the problems of traditional isolation nets being difficult to disassemble and inconvenient to clean, and improves maintenance efficiency. Attached Figure Description

[0031] 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.

[0032] Reference Figure 1 and Figure 2The present invention provides an embodiment of a dustproof and insect-proof louver, comprising a window frame 1 made of aluminum alloy. The window frame 1 serves as a frame for installing and fixing the louver. Multiple window slats 8 are rotatably connected to the inner wall of the window frame 1 via a pivot. The window slats 8 are made of aluminum alloy and their function is to control the indoor lighting and ventilation effect by adjusting their angle. The window slats 8 are arranged in an array inside the window frame 1. Protective components are provided on the side wall of the window frame 1, and an adjustment component is provided inside the window frame 1 to adjust the angle of the window slats 8.

[0033] The adjustment assembly includes a drive motor 4, which serves as the power source for adjusting the angle of the window slats 8. The drive motor 4 is fixedly connected to the interior of the window frame 1. A rocker arm 5, made of metal, is fixedly connected to the output end of the drive motor 4 via a coupling. The rocker arm 5 rotates under the drive of the drive motor 4, converting the motor's rotational motion into its own oscillation, which in turn drives other components. Notches 9 are provided at the bottom and top of the outer wall of the window slats 8. These notches 9 reduce gaps when the upper and lower slats are closed, enhancing the sealing performance of the louvers. Connecting arms 7 are fixedly connected to the side walls of the window slats 8. Their function is to connect the window slats 8 and the linkage arms 6, transmitting the movement of the linkage arms 6 to the window slats 8 to achieve window slat angle adjustment. The angle of leaf 8 is adjusted. A linkage arm 6 is set on the side of the connecting arm 7. One side wall of the connecting arm 7 is rotatably connected to the side wall of the linkage arm 6 through a pin. One side wall of the rocker arm 5 is rotatably connected to the middle position of the side wall of the linkage arm 6 through a pin. The protective component includes an isolation net 2, which is made of metal wire mesh. Its function is to block dust and insects and prevent them from entering the room through the window. The side wall of the isolation net 2 is slidably connected to the side wall of the window frame 1. Sensors 3 are fixedly connected to the top and bottom of the outer wall of the isolation net 2. Locking posts 10 are set at the four corners of the isolation net 2. Their function is to lock the isolation net 2 to the window frame 1 after the isolation net 2 is installed in place to prevent it from shaking or falling off. The outer wall of the locking post 10 is slidably connected to the inside of the window frame 1 and the isolation net 2.

[0034] Specifically, when using this dustproof and insect-proof venetian blind, in severe weather such as strong winds, the sensors 3 at the top and bottom of the isolation net 2 start working. When the wind speed exceeds the set threshold, indicating a strong wind, the sensor 3 transmits a signal to the control system of the drive motor 4. At this time, the output of the drive motor 4 drives the rocker arm 5 to rotate. One end of the rocker arm 5 is rotatably connected to the middle of the side wall of the linkage arm 6. When the rocker arm 5 rotates, it makes a circular motion around the connection point. Through its connection with the linkage arm 6, the linkage arm 6 moves up and down in the vertical direction. One end of the connecting arm 7 is rotatably connected to the linkage arm 6, and the other end is fixedly connected to the window slat 8. When the linkage arm 6 moves up and down, the connecting arm 7 moves up and down with the linkage arm 6. The connecting point of the linkage arm 6 rotates around the axis, and the connecting arm 7 is fixedly connected to the window leaf 8. When the connecting arm 7 rotates, it drives the window leaf 8 to rotate around the rotating connecting point on the inner wall of the window frame 1. The window leaf 8 gradually rotates from the initial horizontal or inclined angle to a suitable angle, such as a fully closed or partially closed angle. Through this movement process, the automatic opening and closing of the window leaf 8 is completed. When the windy weather passes and the sensor 3 detects that the wind speed has returned to normal, it will control the drive motor 4 to rotate in the opposite direction again, so that the window leaf 8 returns to its original angle. This achieves the effect of adjusting the angle of the window leaf 8 in real time according to the actual environmental changes, effectively improving the dustproof and insect-proof performance of the venetian blinds and providing a more comfortable indoor environment.

[0035] Reference Figure 3Multiple ball bearings 11 are slidably connected inside the locking post 10. The ball bearings 11 are distributed in a circumferential shape at the bottom of the locking post 10. Their function is to cooperate with the holes inside the window frame 1 when the locking post 10 is working to lock the isolation net 2. When the locking post 10 is in the locked state, the ball bearings 11 are partially embedded in the holes inside the window frame 1, preventing the isolation net 2 from moving. Limiting plates 17 are fixedly connected to the top of the inner wall of the locking post 10. The limiting plates 17 have holes inside that are consistent with the cross-section of the protrusion 16 and the top post 14. The function of the limiting plates 17 is to limit the displacement range of the inner post 12. Inner posts 12 are slidably connected inside the locking post 10. The bottom of the outer wall of the inner post 12 has a receiving groove 13. The receiving groove 13 is a groove formed on the inner post 12 by mechanical processing. The function of the receiving groove 13 is to provide a receiving space for the ball bearing 11 when the isolation net 2 is unlocked, so that the ball bearing 11 can slide into the hole inside the window frame 1, thereby releasing the locked state of the isolation net 2. The top of the inner column 12 is fixedly connected to the top of the top column 14, and multiple auxiliary blocks 15 are fixedly connected to the top of the outer wall of the top column 14. The auxiliary blocks 15 are made of rubber and have a certain anti-slip texture on the surface. The function of the auxiliary blocks 15 is to provide the user with a force point to facilitate manual rotation of the top column 14. Multiple protrusions 16 are fixedly connected to the bottom of the outer wall of the top column 14. The function of the protrusions 16 is to cooperate with the holes on the limiting plate 17. The position of the protruding block 16 is changed by rotating the top column 14, thereby controlling the displacement of the inner column 12. The auxiliary block 15 and the protruding block 16 are distributed in a circumferential shape on the outer wall of the top column 14. The side wall of the top column 14 is provided with a return spring 18. The function of the return spring 18 is to release elastic potential energy when the protruding block 16 is aligned with the hole of the limiting plate 17, and push the top column 14 and the inner column 12 to move outward, thereby unlocking the isolation net 2. The return spring 18 is sleeved on the outer wall of the inner column 12. One end of the return spring 18 is slidably connected to the bottom of the top column 14, and the other end of the return spring 18 is fixedly connected to the inside of the locking column 10.

[0036] Specifically, when the outer surface of the isolation net 2 traps a large number of insects and needs to be disassembled and cleaned, the user first locates the auxiliary block 15 on the top of the outer wall of the top post 14, pinches the auxiliary block 15 with their fingers, and then rotates the top post 14. The protruding block 16 is fixedly connected to the top post 14. When the top post 14 rotates, the protruding block 16 also rotates and moves accordingly. As the top post 14 continues to rotate, the protruding block 16 gradually changes position. When the position of the protruding block 16 is consistent with the hole opened by the limiting plate 17, the return spring 18, which was originally restricted and squeezed by the limiting plate 17 and was in a compressed state, is released from its compressed state, generating an upward return thrust. Under the action of this thrust, the top post 14 moves outward along the sliding channel inside the locking post 10, and drives the inner post 12 to move synchronously. The displacement of the inner post 12 causes the receiving groove 13 to slide upward as well, inside the locking post 10. The ball bearing 11, which was originally partially embedded in the hole inside the window frame 1 due to the pressure from the outer wall of the inner column 12, loses the pressure from the outer wall of the inner column 12. The ball bearing 11 slides from the hole inside the window frame 1 into the receiving groove 13. When the ball bearing 11 is fully inserted into the receiving groove 13, the locking state of the isolation net 2 is released. At this time, the user can remove the isolation net 2 from the side wall of the window frame 1 for cleaning. After cleaning, the user reverses the operation, installs the isolation net 2 back onto the side wall of the window frame 1, and then rotates the top column 14 to make the protrusion 16 leave the hole of the limiting plate 17. The return spring 18 is compressed again, and the ball bearing 11 is re-embedded in the hole inside the window frame 1, completing the locking of the isolation net 2. This achieves the effect of quick disassembly and assembly of the isolation net 2 for easy maintenance and cleaning, ensuring that the isolation net 2 can effectively play its role in preventing dust and mosquitoes for a long time.

[0037] Working Principle: When using this dustproof and insect-proof venetian blind, in severe weather such as strong winds, the sensors 3 at the top and bottom of the isolation net 2 will detect the weather conditions. At this time, the sensors 3 control the drive motor 4 to rotate. The rotation of the drive motor 4 drives the rocker arm 5 to rotate. The rotation of the rocker arm 5 causes the linkage arm 6 to move up and down. The movement of the linkage arm 6 causes the multiple connecting arms 7 connected to its side wall to rotate. The rotation of the connecting arms 7 causes the angle of the window slats 8 to rotate, thus completing the automatic opening and closing of the window slats 8. This achieves the effect of adjusting the angle of the window slats 8 in real time according to changes in the actual environment. When the isolation net 2 has trapped a large number of insects and needs to be disassembled and cleaned, the user can manually adjust the angle using the auxiliary... The auxiliary block 15 rotates the top column 14, and the rotation of the top column 14 causes multiple protrusions 16 on its bottom outer wall to rotate as well. When the position of the protrusions 16 is consistent with the hole opened by the limiting plate 17, the compression state of the return spring 18 is released, generating a return thrust, which pushes the top column 14 to move outward. The displacement of the top column 14 causes the inner column 12 to move synchronously, which in turn causes the receiving groove 13 to slide upward. At this time, the ball bearing 11 loses the pressure from the outer wall of the inner column 12 and slides from the hole inside the window frame 1 into the receiving groove 13, thereby completing the unlocking of the isolation net 2, allowing the user to remove it for cleaning, thus achieving the effect of quick disassembly and assembly of the isolation net 2 for easy maintenance and cleaning.
