Description

Technical Field

[0001] The utility model relates to the technical field of ventilation duct accessories, in particular to an adjustable ventilation window for a ventilation duct. Background Art

[0002] An adjustable air window is a window with an adjustable area opened above a ventilation duct, damper, or air wall. By adjusting the area of ​​the window, the air flow through the ventilation duct can be effectively controlled to meet different ventilation needs. Referring to the existing literature, an adjustable ventilation window for a ventilation duct (CN221611566U) is provided. By configuring a limit groove, a limit structure, a limit spring, a limit slider, a limit rod, a connecting rod, a connecting handle, a first rotating shaft, a first stopper, a second rotating shaft, and a second stopper, the window body can be easily disassembled and assembled. The operation is simple and convenient, and no screws or tools are required, thereby preventing the screws from rusting and becoming unable to be disassembled.

[0003] The current adjustable wind window is usually composed of components such as shutters. As shown in the above-mentioned literature, the inclination angle of the baffle is adjusted by rotating the reset shaft to adjust the air volume. Although the adjustment method of the shutter is relatively simple, there is usually a certain gap between the blades to ensure the flexible rotation of the blades. At the same time, the above-mentioned literature also requires manual adjustment of the angle of each baffle. Therefore, an adjustable ventilation window for a fully closable automatic ventilation duct is designed. Utility Model Content

[0025] Reference Figure 1-4 An adjustable ventilation window for a ventilation duct includes: a ventilation window main body 1 and a mounting base 4. The back of the ventilation window main body 1 is fixedly connected to the mounting base 4. The mounting base 4 has multiple groups of filter screens 5 built in. It is fixed to the ventilation duct through the mounting base 4. The introduced gas will first pass through the multiple groups of filter screens 5 to filter out impurities, and then be discharged through the ventilation window main body 1.

[0026] For details, please refer to Figure 3The device is provided with an adjustment component inside the ventilation window body 1. The driving source of the adjustment component is a servo motor 3. The servo motor 3 is fixedly installed above the ventilation window body 1 (such as Figure 1 As shown), the output end of the servo motor 3 is connected to the bidirectional screw 9, and the external thread of the bidirectional screw 9 is connected to two screw seats 10. The two screw seats 10 are symmetrically distributed around the center of the bidirectional screw 9. At the same time, the screw seats 10 are fixed to one end of the adjustment plate 2 through a connecting rod 11.

[0027] like Figure 1 and Figure 4 As shown, the ventilation opening 14 can be completely closed when the two adjustment plates 2 are in contact.

[0028] In this embodiment, when the servo motor 3 is running, it can drive the bidirectional screw 9 to rotate, and then drive the two screw seats 10 connected to the external threads of the bidirectional screw 9 to move in the opposite direction along the bidirectional screw 9. The two screw seats 10 drive the two adjustment plates 2 to move in the opposite direction through the connecting rod 11. When the two adjustment plates 2 move closer or apart, the opening size of the vent 14 is adjusted.

[0029] Furthermore, the other ends of the two adjustment plates 2 are fixed with sliders 13 through connecting rods 11, and the sliders 13 slide outside the slide rods 12. Therefore, when the two adjustment plates 2 move in a straight line, the sliders 13 can support the other sides of the two adjustment plates 2 and move synchronously at the same time.

[0030] In this embodiment, Figure 4 As shown, mounting grooves 15 are provided on both sides of the upper end of the ventilation window body 1, the slide rod 12 is fixed in the mounting groove 15 on the left side, the two sliders 13 slide in the mounting groove 15 on the left side, the bidirectional screw rod 9 is rotatably connected in the mounting groove 15 on the right side, and the two screw rod seats 10 move linearly in the mounting groove 15 on the right side.

[0031] A movable groove 16 is provided on one side of the installation groove 15 . The movable groove 16 is communicated with the installation groove 15 . The movable groove 16 is used for connecting the rod 11 to move linearly.

[0032] At the same time, two movable grooves 2 17 are provided between the two movable grooves 16 . The movable grooves 2 17 are distributed at the upper and lower ends and are both connected to the movable groove 1 16 . The movable grooves 2 17 are used for the two adjustment plates 2 to pass through.

[0033] In addition, a limiting plate 18 is fixed above the installation groove 15 on the left side. The limiting plate 18 is used to limit the moving range of the slider 13 to prevent the slider 13 from falling out.

[0034] Specifically, such as Figure 2As shown, a plurality of slots 7 are provided above the mounting base 4 for inserting the corresponding filter screens 5. At the same time, a magnetic block 6 is integrally connected to the bottom of the filter screen 5, and a magnetic groove 8 is provided at the inner bottom of the mounting base 4, which can just be inserted into the magnetic block 6.

[0035] Furthermore, the magnetic groove 8 is equipped with a magnetic sheet with opposite magnetic properties to the magnetic block 6, which can form north and south poles with the magnetic block 6, so that the filter 5 can be magnetically attracted to the mounting base 4 through the magnetic block 6, thereby improving the installation stability. At the same time, the plug-in connection method facilitates subsequent quick disassembly and replacement.

[0036] Working principle: When using the utility model, the bidirectional screw 9 is driven to rotate by the servo motor 3, so that the two screw seats 10 move in opposite directions along the bidirectional screw 9, and the two screw seats 10 can drive the two adjustment plates 2 to move in opposite directions through the connecting rod 11. The two adjustment plates 2 can be completely closed to seal the vents 14. Compared with the traditional shutter design, the gap in the closed state can be reduced. At the same time, the automated operation is simpler and there is no need to adjust the blade angle one by one. A plurality of slots 7 are provided above the mounting seat 4 for inserting the corresponding filter screen 5. At the same time, a magnetic block 6 is integrally connected to the bottom of the filter screen 5. The filter screen 5 can be magnetically attracted to the mounting seat 4 through the magnetic block 6, which improves the installation stability. At the same time, the plug-in connection method facilitates subsequent quick disassembly and replacement.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
