A side strip 2 is fixedly connected to the front end of the ventilation pipe 1. Multiple movable slots 3 are opened on the outer side of the rear end of the ventilation pipe 1. Movable blocks 4 are movably connected inside each movable slot 3. A movable frame 5 is movably connected to the outer side of the rear end of the ventilation pipe 1. A fixed plate 6 is fixedly connected to the rear side of the movable frame 5. Multiple first fasteners 7 are threaded through the inside of the fixed plate 6. The ends of the first fasteners 7 are threaded to the middle of the movable blocks 4. A splicing joint 8 is fixedly connected to the rear end of the ventilation pipe 1. A guide pipe 9 is provided at the rear end of the ventilation pipe 1. A splicing groove 10 is provided on the inner wall of the front end of the guide pipe 9. The inner wall of the splicing groove 10 fits tightly with the outer wall of the splicing joint 8. A guide plate 11 is fixedly connected to the inner wall of the lower end of the guide pipe 9 to prevent rainwater from entering. A partition 12 is rotatably connected to the front side of the side strip 2. A ventilation opening 13 is opened in the middle of the partition 12.
[0024] First, a square hole is made in the wall. Then, the ventilation pipe 1 is installed in the square hole. Next, the movable frame 5 and the fixed plate 6 are fitted onto the rear end of the ventilation pipe 1, so that the movable frame 5 is tightly attached to the wall. Then, the first fastener 7 is connected to the movable block 4 to fix the movable frame 5 and the fixed plate 6. The movable frame 5, the fixed plate 6, and the movable block 4 can move back and forth, which can be used for walls of different thicknesses. Then, the splicing groove 10 is made to cooperate with the splicing joint 8, so that the guide pipe 9 can be installed at the rear end of the ventilation pipe 1. The side strip 2 and the movable frame 5 are tightly attached to the wall surface, which can achieve a sealing effect. The guide plate 11 can maintain ventilation while preventing rainwater from entering. The partition 12 can protect the ventilation pipe 1. Ventilation is maintained through the ventilation opening 13, preventing large debris from entering the channel.
[0025] Reference Figure 1 and Figure 4 A fixed bracket 14 is fixedly connected to the left and right sides of the front end of the ventilation pipe 1. A pull-out plate 16 is slidably connected to the inner side of the fixed bracket 14. A connecting plate 15 is fixedly connected to the front end of the pull-out plate 16. A rotating shaft 17 is rotatably connected to both the left and right ends of the connecting plate 15. A fan blade 19 is fixedly connected to the front end of the rotating shaft 17. A motor 18 is fixedly connected to both the left and right ends of the rear side of the connecting plate 15.

Then, the first fastener 7 is connected to the movable block 4 to fix the movable frame 5 and the fixed plate 6. The movable frame 5, the fixed plate 6 and the movable block 4 can move back and forth, which can be used for walls of different thicknesses. Then, the splicing groove 10 is made to cooperate with the splicing joint 8, so that the guide pipe 9 can be installed at the rear end of the ventilation pipe 1. The pull plate 16 can slide back and forth inside the fixed frame 14, so that the fan blade 19 and the motor 18 can move back and forth and protrude from the front end of the ventilation pipe 1 for easy cleaning and maintenance. The filter plate 21 is installed at the front end of the T-shaped plate 20. After the motor 18 and the fan blade 19 are pushed into the ventilation pipe 1, the second fastener 22 passes through the four corners of the filter plate 21 and is connected to the fixed frame 14 to fix the fan blade 19 and the motor 18.
