[0002] Ventilation ducts are essential components in the use of building HVAC. As the name suggests, their main function is ventilation. Commonly used ventilation ducts generally have square and cylindrical structures. They are mainly made of metal and have higher durability.

[0003] Publication No. CN220609577U discloses a filter device for ventilation pipes, belonging to the technical field of filter devices. At present, oil discharged from oil smoke is easily adsorbed on the inner wall of the ventilation pipe, affecting the service life of the ventilation pipe. The utility model includes two push-pull plates movably connected to the surface of the filter body, a first filter plate is fixedly connected to one side of the push-pull plate located on the front side, a first filter screen is fixedly connected to the surface of the first filter plate, a second filter plate is fixedly connected to one side of the push-pull plate located on the rear side, a second filter screen is fixedly connected to the surface of the second filter plate, two electric telescopic rods are fixedly connected to the surface of the filter body, and a cleaning plate is fixedly connected to one end of the electric telescopic rod. The utility model reduces the adhesion of oil by the mixed liquid, and then performs preliminary cleaning by the first cleaning brush and the second cleaning brush, thereby avoiding oil from adhering to the inside of the ventilation pipe, and improving the service life of the ventilation pipe, so as to solve the problem that oil is easily adsorbed on the inner wall of the ventilation pipe when oil smoke is discharged, affecting the service life of the ventilation pipe. Although the ventilation duct can clean the first filter plate and the second filter plate by the first cleaning brush and the second cleaning brush, the filter plates will age and need to be replaced with new ones after long-term use. The filter plates of the ventilation duct are fixed by welding. Although the structure is relatively stable, it is time-consuming to inspect and replace the filter nets, which needs to be improved.
