When the first compression platform 55 moves to the bottom or the second compression platform 55 compresses the fallen leaves to the point where they can no longer be compressed, the air pressure in the storage box 6 will continue to increase, but the compression platform 55 will not move until the pressure valve 56 is broken and the air flows out, thereby completing the process of compressing the fallen leaves.
