[0028] This invention, through the coordinated arrangement of the exhaust pipe, slot, folding soft cover, cylinder, air rod, and arc frame, allows the device to operate with multiple folds on the outer surface of the folding soft cover that allow for easy extension and retraction. After the second transfer pipe is used and heat accumulates on its outer surface, the operator drives the cylinder to control the air rod for extension and retraction. The air rod then moves the arc frame upwards, causing the outer surface of the heat sink to contact the outer surface of the second transfer pipe. The operator then drives a third motor to control the rotation of a third shaft, which in turn rotates the third fan blade frame to generate airflow. This, combined with the heat sink, enhances the dissipation of residual heat from the outer surface of the second transfer pipe, strengthens the protection of the pipe body, and allows airflow through the second permeable mesh. This improves the overall flexibility of the device, making it easier to adjust, increasing its efficiency, saving labor costs and working time, and enhancing its overall convenience.
