A baffle is fixedly connected between two sliders. A spring is fixedly installed inside the sliding grooves, and the other end of the spring is fixedly connected to the slider. A rotating shaft is rotatably connected inside the pipe inlet body along the air inlet direction behind the baffle. A power fan blade is fixedly installed on the outer wall of the rotating shaft. A cam is fixedly installed at the bottom end of the rotating shaft. A rotating rod is installed at the bottom end of the cam. The rotating rod and the cam are rotatably connected. A connecting rope is fixedly installed on the rotating rod, and the other end of the connecting rope is fixedly connected to the baffle. An exhaust fan is fixedly installed inside the pipe inlet body.
