Common louver air vents include: single-layer louver air vents, double-layer louver air vents, sidewall grille air vents, slotted grille air vents, etc.

[0003] The double-layer louver air vent is composed of double layers of blades. The front layer of blades is adjustable, and the rear layer of blades is fixed. According to needs, an opposed multi-blade air volume regulating valve can be configured to adjust the air volume of the air vent. Where the front blades are vertically arranged and the rear blades are horizontally arranged, it is called the VH type. By changing the installation angle of the vertical blades, the diffusion angle of the air flow can be adjusted.

[0004] One group of louver blades inside the double-layer louver air vent is fixed, which limits the adjustable air vent orientation of the louver air vent and is not convenient for use. Moreover, the louver blades of the louver air vent are fixedly installed, which is not conducive to disassembling, cleaning and maintaining the louver blades, making the use of the louver air vent subject to many limitations. Therefore, it is very necessary to propose a double-layer adjustable louver air vent to solve the above problems. Content of the Utility Model

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] The present utility model provides a double-layer adjustable louver air outlet as shown in Figures 1 to 4 Figure 10, which includes a mounting plate 1. A lower frame 2 is fixedly installed at the bottom of the mounting plate 1. An upper frame 3 is hinged to the top of the mounting plate 1. A plurality of rotating rods 4 are respectively rotatably connected to the inner sides of the upper frame 3 and the lower frame 2. L-shaped grooves 5 are formed at the tops of the plurality of rotating rods 4. Louver blades 6 are slidably arranged inside the L-shaped grooves 5. Rectangular plates 7 are rotatably connected to the ends of the plurality of rotating rods 4. Taking the mounting plate 1 as the center line, a first push rod 8 is rotatably connected to the end of the rectangular plate 7 located above the mounting plate 1, and a second push rod 9 is rotatably connected to the end of the rectangular plate 7 located below the mounting plate 1. A limiting rod 10 is rotatably connected to the top of the upper frame 3, and the bottom end of the limiting rod 10 is threadedly connected to the top of the mounting plate 1. During use, the louver blades 6 can be quickly installed and disassembled through the L-shaped grooves 5, so as to facilitate the cleaning and maintenance of the louver blades 6. By moving the first push rod 8 and the second push rod 9, the inclination angles of the louver blades 6 in the upper frame 3 and the lower frame 2 can be respectively adjusted, thereby increasing the air outlet range of the louver air outlet and facilitating the use by the user.

[0024] During specific use, the louver air outlet is usually installed at the top of the indoor wall, that is, the lower frame 2 is installed at the top of the wall. At this time, the upper frame 3 faces downward. After rotating the limiting rod 10 so that it no longer contacts the mounting plate 1, the upper frame 3 can be opened. At the same time, the upper frame 3 can be locked on the mounting plate 1 by rotating the limiting rod 10. The rotating rods 4 in the lower frame 2 can quickly install and disassemble the louver blades 6 through the L-shaped grooves 5. The plurality of louver blades 6 in the lower frame 2 are adjusted by the second push rod 9. When pulling the second push rod 9, the second push rod 9 pulls the plurality of rectangular plates 7, so that the rotating rods 4 follow the rectangular plates 7 to deflect, so as to achieve the effect of adjusting the louver blades 6 in the lower frame 2. The upper frame 3 is the same as the lower frame 2. The inclination angle of the louver blades 6 in the upper frame 3 can be adjusted by pulling the first push rod 8.

[0025] Further, the rotating rods 4 inside the upper frame 3 and the lower frame 2 are designed with rotationally symmetric distribution. The first push rod 8 and the second push rod 9 are used to adjust the orientation of the louver blades 6 inside the upper frame 3 and the lower frame 2, so as to increase the adjustable angle of the air outlet of the louver air outlet for convenient use.

[0026] As Figure 1 and Figure 2 and Figure 4 shown, two fixing plates 11 are fixedly installed at the top of the upper frame 3. An activity rod 12 is rotatably connected between the two fixing plates 11. A dust-proof cloth 13 is wound around the side of the activity rod 12. Two U-shaped blocks 14 are fixedly installed at the top of the upper frame 3. During use, the dust-proof cloth 13 can be pulled by rotating the activity rod 12. When the louver air outlet is not used for a long time, the dust-proof cloth 13 can prevent dust from entering the louver air outlet, and the dust-proof cloth 13 can be fixed by the U-shaped blocks 14 so that it can cover the upper frame 3.

[0027] During specific use, one end of the dust-proof cloth 13 is fixedly connected to the side of the activity rod 12. When the dust-proof cloth 13 is not used, the activity rod 12 is rotated to wind the dust-proof cloth 13 around the side of the activity rod 12. When the louver air outlet is not used for a long time, the activity rod 12 is rotated to pull the dust-proof cloth 13. A round rod is fixedly connected to one end of the dust-proof cloth 13, and the round rod can be stuck between the two U-shaped blocks 14 to fix the dust-proof cloth 13, so as to ensure that the dust-proof cloth 13 can cover the upper frame 3 and prevent dust from entering the louver air outlet.

[0028] Further, two L-shaped plates 15 are fixedly installed at the top of the upper frame 3. The two L-shaped plates 15 are designed with symmetric distribution. When pulling the dust-proof cloth 13, the dust-proof cloth 13 is passed through the two L-shaped plates 15, and the L-shaped plates 15 can limit both sides of the dust-proof cloth 13 to further prevent dust from entering the louver air outlet.

[0029] As Figure 4 shown, a chute 16 is formed on the side of the upper frame 3. A filter plate 17 is slidably arranged inside the chute 16. During use, the filter plate 17 can filter the air blown out by the louver air outlet to ensure air quality, and the filter plate 17 can be taken out through the chute 16 at any time for easy cleaning and replacement.

[0030] During specific use, the filter plate 17 can be moved to the inside of the upper frame 3 through the chute 16. When air is discharged from the upper frame 3 to the outside, the dust mixed in the air will be adsorbed by the filter plate 17 to ensure the cleanliness of the air. The filter plate 17 can be taken out conveniently through the chute 16, so that the filter plate 17 can be cleaned and replaced regularly.

[0031] Furthermore, a T-shaped plate 18 is threadedly connected to the top of the filter plate 17, and a ribbon 19 is fixedly connected to the top of the T-shaped plate 18. Through the ribbon 19, the direction of the air blown by the louver air outlet can be directly observed visually, so that after the user adjusts the orientation of the louver blades 6, the direction in which the ribbon 19 flutters can be used for calibration and confirmation. The ribbon 19 can be removed through the T-shaped plate 18, so as to facilitate the user to choose whether to use it or not.

[0032] Still further, a threaded hole 20 is formed in the outer side of the upper frame 3, and the thread of the threaded hole 20 is mutually engaged with the thread of the T-shaped plate 18. When the user does not want to use the ribbon 19, the T-shaped plate 18 can be rotated to remove it from the filter plate 17, and then it can be installed on the side surface of the upper frame 3 through the threaded hole 20 to complete the storage, which is convenient for subsequent reuse.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
