Solution:
1. According to the actual size of the inner diameter of the air duct, buy a PVC sewer pipe with a diameter of 18cm,
2 elbows with 90 degrees, a proper amount of special glue and 4 vats of foaming agents.
2. Saw off the pipe about 40cm in length and glue the elbows together. Insert the pipe into the air duct, and align the elbow with the position where the range hood, ventilator or bath bully will be installed later. Use wood square or broken bricks to squeeze tightly in the gap between the pipe and the air duct to prevent the pipe from falling off. After foaming, it can be fixed. After the ceiling construction, let the carpenter hold it under the elbow and fix it.
3. Depending on the distance between the installation position and the nozzle, connect the remaining pipes according to the actual situation and extend them.
