[0029] Further, the machine body 1 is provided with a mounting disc 3, the mounting disc 3 is fixedly installed with the first fan 21 and the second fan 22 respectively, the air duct switching mechanism comprises a movable baffle 4, a rotating shaft 41 is arranged between the movable baffle 4 and the mounting disc 3, the movable baffle 4 swings forward or reversely around the rotating shaft 41 to make the first air duct and the second air duct selectively conducted, the structure and movement mode of the movable baffle 4 are relatively simple, and the movable baffle 4 is not easy to fail, and the overall working stability is better.

[0030] Further, the upper side and / or the lower side of the movable baffle 4 is provided with a convex rib part 42, which protrudes towards the front and back directions of the movable baffle 4. The convex rib part 42 can not only improve the structural strength of the movable baffle 4, but also has a certain wind blocking effect. When the air flow hits the movable baffle 4, the air flow will spread along the movable baffle 4 in the up-down direction.
