The first end has a first entrance and a first exit. The second end has a second entrance and a second exit. The partition is installed inside the air inducing tube. The partition divides the internal room of the air inducing tube into a first air inducing space and a second air inducing space. The first air inducing space makes the first entrance communicate with the second exit. The second air inducing space makes the first exit communicate with the second entrance. The fan is arranged with the air inducing tube to induce air flow.
