Among them, the "indoor energy-saving ventilation duct" disclosed by the application number "CN217737499U" has solved the technical disadvantages of being blocked after long-term use and affecting the normal use of the device. However, in actual use, similar structures still have many defects. For example, the turning point of the pipe adopts a right-angle connection. When the airflow is directly connected, it produces a large impact and vortex at the turning point, thereby increasing the resistance of air flow, which not only reduces the ventilation efficiency, but also may cause energy loss, thereby reducing the quality of indoor ventilation, and when adjusting the size of indoor ventilation, the airflow compression and the friction of the valve plate will produce a large noise, which will not only affect the comfort of the use environment, but also may have a negative impact on people's health and work efficiency.

[0023] The regulating mechanism 2 includes a regulating tube 201, a regulating chamber 202 is arranged at the central position of the regulating tube 201, a fan 401 is fixedly installed at the other end of the regulating chamber 202 through a diamond rod 402, and a fan blade 4 is fixedly installed at the output end of the fan 401, a valve plate 501 is rotatably installed at one end of the regulating chamber 202, a regulating motor 5 whose output end is connected to the valve plate 501 is fixedly installed at the top of the regulating tube 201, a sound insulation chamber 203 is arranged outside the regulating chamber 202, and the inside of the sound insulation chamber 203 is filled with sound insulation cotton 204;

[0024] The fixing mechanism 3 includes a frame plate 303 , with holding rings 301 fixedly installed on both sides of the frame plate 303 , a shock absorbing pad 304 fixedly installed at the central position of the inner side of the frame plate 303 , and shock absorbing springs 305 fixedly installed around the inner side of the frame plate 303 .

[0025] Based on the above-mentioned structural setting, the high-efficiency ventilation duct group is composed of a fixing mechanism 3, a duct mechanism 1, and an adjusting mechanism 2. The fixing mechanism 3 is a fixed grouping treatment of the ventilation duct, the duct mechanism 1 is an airflow guiding structure for ventilation operations in the building, and the adjusting mechanism 2 is an adjusting structure of the ventilation duct for adjusting the size of the ventilation airflow in the building. Specifically, in the working project, one end of the duct body 101 extends to the outside of the building, and the other end of the duct body 101 extends to the inside of the building through the shunt pipe 105. Therefore, the outdoor air can be guided to the inside of the building through the duct body 101, realizing the function of ventilation treatment in the building. The arc elbow 103 can The pipe body 101 and the diverter pipe 105 are connected in an arc-shaped manner. The arc-shaped connection can reduce air flow resistance, make the airflow transition more smoothly, reduce energy loss, and thus improve the ventilation efficiency in the building. The design of the elbow can better adapt to the layout and installation requirements of the ventilation duct group, reduce the system instability caused by right-angle turns, and a reasonable elbow design can ensure that the airflow is evenly distributed in the duct to avoid airflow dead corners or vortex phenomena, thereby improving the stability of the entire ventilation duct group. The regulating pipe 201 is fixedly installed at one end of the pipe body 101, and the fan 401 is fixedly installed in the regulating cavity 202 through the diamond rod 402. The fan 401 drives the fan blades 4 to rotate forwardly to extract external air, thereby accelerating the ventilation efficiency in the building and realizing the function of efficient ventilation in the room. The fan 401 drives the fan blades 4 to flip to extract and discharge the air in the building, thereby realizing the function of exhausting the building. The regulating motor 5 drives the valve plate 501 to rotate in the regulating chamber 202 to control the air volume of the pipeline body 101 when ventilating the building. Therefore, it is convenient for personnel to control the ventilation volume in the building through the pipeline group according to actual needs. The sound insulation chamber 203 and the sound insulation cotton 204 can soundproof and reduce the noise when the fan 401 drives the fan blades 4 to rotate, and can also The noise generated by the airflow compression is isolated and reduced on the valve plate 501, thereby reducing the noise of the ventilation duct group when efficiently ventilating the building, and also reducing the noise transmission when the airflow compression is reduced, thereby increasing the comfort of the personnel use environment. The holding ring 301 can be mounted on the outer wall of the pipe body 101, and the frame plate 303 can connect the holding ring 301 and the pipe body 101. Therefore, the two groups of pipe bodies 101 can be fixed in groups through the holding ring 301 and the frame plate 303. The shock-absorbing pad 304 and the shock-absorbing spring 305 can isolate the vibration between the pipe bodies 101 during operation, thereby avoiding mutual interference between the pipe bodies 101 during operation.

[0026] Furthermore, a first flange 102 is fixedly mounted on one end of the pipe body 101, and a second flange 106 is fixedly mounted on the bottom of the diverter pipe 105. The first flange 102 facilitates the connection between the pipe body 101 and an external filtering mechanism or protective mechanism, so that the air entering the building through the pipe body 101 can be filtered and purified, and the second flange 106 facilitates the connection between the diverter pipe 105 and an external exhaust hood, thereby increasing the aesthetics and safety of ventilation inside the building.

[0027] Furthermore, multiple sets of rib rings 104 are fixedly installed at equal distances on the outer walls of the pipeline body 101, the curved bend pipe 103, and the diverter pipe 105. The rib rings 104 increase the overall strength of the pipeline body 101, the curved bend pipe 103, and the diverter pipe 105, and prevent the pipeline body 101, the curved bend pipe 103, and the diverter pipe 105 from being dented and deformed when used for a long time.

[0028] Furthermore, a rubber ring 502 is fixedly mounted on the outer wall of the valve plate 501, and ribs 503 are fixedly mounted on the front and back of the valve plate 501. The rubber ring 502 increases the tightness of the valve plate 501 when in contact with the inner wall of the regulating chamber 202, and improves the stability of the valve plate 501 when regulating the airflow of the ventilation duct group, and the ribs 503 increase the overall strength of the valve plate 501, and avoid deformation and damage caused by the impact of airflow for a long time.

[0029] Furthermore, a plurality of rubber rods 302 are fixedly installed at equal distances on the inner wall of the holding ring 301. The rubber rods 302 increase the softness of the inside of the holding ring 301, and can protect the holding ring 301 when it is sleeved on the outside of the pipeline body 101, thereby increasing the stability and safety of the connection between the holding ring 301 and the pipeline body 101.

[0030] Furthermore, a fixing plate 306 is fixedly installed at the bottom of the frame plate 303, and a rubber pad 307 is fixedly installed at the bottom of the fixing plate 306. The fixing plate 306 can be used to install and fix the ventilation pipe group, and the rubber pad 307 can perform elastic shock absorption on the bottom of the fixing plate 306, thereby reducing the interference and influence of external vibration on the ventilation pipe group.
