[0002] Ventilation ducts are widely used in various types of buildings, especially in commercial buildings, factories, and underground facilities, to ensure air circulation, remove harmful gases, or regulate temperature. Ventilation duct systems effectively maintain ambient air quality, provide comfortable indoor airflow, and enhance the comfort and health of the space.

[0003] Traditional ventilation ducts typically consist of the duct body, fan, valves, and connectors. The duct body is responsible for air transmission, the fan provides power, the valves control the airflow, and the connectors link the various components into a complete ventilation system to ensure smooth airflow.

[0004] Traditional ventilation ducts cannot regulate airflow because their design lacks flexible airflow adjustment devices or the adjustment system is slow to respond. In many traditional duct systems, airflow is determined by the fixed power of the fan and the duct size, and airflow adjustment usually relies on manually adjusting valves or setting a fixed flow rate. This makes it impossible to flexibly adjust the airflow according to different environmental needs in actual use. As a result, excessive airflow leads to energy waste and noise pollution, while insufficient airflow leads to poor air circulation, affecting indoor air quality and comfort. Utility Model Content

[0032] 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.

[0033] Reference Figures 1-3 An embodiment of this utility model is provided: an energy-saving ventilation duct with adjustable air volume, including a pipe body 1, a fixing ring 2 fixedly connected to the side wall of the pipe body 1, a side frame 3 fixedly connected to the side wall of the fixing ring 2, a motor 4 fixedly connected to the side wall of the side frame 3, an output shaft 5 fixedly connected to the output end of the motor 4, and an adjustment component provided inside the fixing ring 2.

[0034] The adjustment assembly includes multiple fan blades 10, which are rotatably connected inside the fixed ring 2. Each fan blade 10 is fixedly connected to a rotating shaft 7, which is rotatably connected inside the fixed ring 2. One end of each rotating shaft 7 is fixedly connected to a rotating plate 9. A rotating rod 8 is rotatably connected to the side wall of the rotating plate 9. A rotating rod 6 is fixedly connected to the outer wall of the output shaft 5. One end of the rotating rod 6 is rotatably connected to the side wall of the rotating plate 9. A connecting assembly is provided on the side wall of the tube body 1.

[0035] Reference Figure 4 and Figure 5 The connecting assembly includes multiple connecting rings 11, the sidewalls of which are fixedly connected to the sidewalls of multiple tubes 1. Multiple connecting posts 12 are slidably connected inside the multiple connecting rings 11. Each connecting post 12 is fixedly connected to a stud 13 on its sidewall. A rotating ring 14 is threadedly connected to the outer wall of the stud 13. Multiple limiting plates 15 are fixedly connected to the outer wall of the rotating ring 14. A sliding shaft 16 is slidably connected inside the connecting post 12. A handle 17 is fixedly connected to one end of the sliding shaft 16 and the other end of the sliding shaft 16. Multiple inner grooves 18 are opened inside the sliding shaft 16. Multiple retaining plates 19 are rotatably connected inside the sliding shaft 16 and slidably connected inside the inner grooves 18. An end plate 20 is fixedly connected to one end of the sliding shaft 16. A spring 21 is provided on the sidewall of the end plate 20.

[0036] Working principle: First, after the motor 4 starts, the output shaft 5 drives the rotating rod 6 on the outer wall to rotate. The rotating rod 6 pushes the rotating plate 9 to rotate around the rotating shaft 7. At the same time, the rotating plate 9 is linked to other rotating plates 9 through the rotating rod 8, so that multiple rotating shafts 7 rotate synchronously. The rotating shaft 7 drives the fan blades 10 in the fixed ring 2 to adjust the angle: the larger the opening angle of the fan blades 10, the larger the ventilation cross section in the pipe body 1, and the greater the air volume; the smaller the angle, the smaller the ventilation cross section, and the smaller the air volume. The angle of the fan blades 10 is precisely controlled by the motor 4 to achieve flexible adjustment of the air volume, solving the problem of fixed air volume in traditional pipes. When connecting the pipe body 1... Insert the connecting post 12 into the connecting ring 11 of the adjacent pipe body 1, pull the handle 17 to drive the sliding shaft 16 to slide inside the connecting post 12, the end plate 20 compresses the spring 21, the inner groove 18 of the sliding shaft 16 rotates out and locks the inner wall of the connecting ring 11, release the handle 17, the spring 21 returns to its original position and pushes the end plate 20, so that the locking plate 19 is tightly locked; rotate the rotating ring 14 to move along the stud 13, the limiting plate 15 on its outer wall presses the connecting ring 11 to enhance the sealing performance, when disassembling, pull the handle 17 in the opposite direction to make the locking plate 19 retract into the inner groove 18, so as to realize the quick disassembly and assembly and stable connection of the pipeline.
