When the air door 72 is opened, the limiting structure rotates with the rotating shaft 722, and when the limiting structure abuts against the fixed plate 71, the rotating shaft 722 is prevented from continuing to rotate, thereby limiting the air door 72 at the set opening position. The plurality of plate-shaped bodies 721 are arranged in parallel, and a guide air channel is formed between adjacent two plate-shaped bodies 721.

[0104] It should be noted that the shape of the plate-shaped body 721 of each air door 72 can be the same or different, and preferably the shape of the plate-shaped body 721 of each air door 72 is set according to the shape of the air outlet of the air blower 5.

[0105] For example, if the shape of the air outlet is square, the shape of the plate-shaped body 721 of each air door 72 can be set to be the same. If the shape of the air outlet is circular, it is preferred that the shape of the plate-shaped body 721 of each air door 72 matches the shape of the air outlet at the installation position.

[0106] ​​In addition, it also needs to be explained that the specific structure of the limiting structure is not limited, for example, the person skilled in the art can set the limiting structure as a limiting block, a limiting plate or a limiting column and the like.

[0107] Preferably, as shown in the drawings, the limiting structure is a limiting block 723, and the limiting block 723 has a stop surface 7231, and when the air door 72 is opened to a set opening position, the stop surface 7231 abuts against the fixed plate 71. Figures 6 to 11

[0108] Exemplarily, the shape of the limiting block 723 is approximately sector-shaped, and the end surface of the top of the limiting block 723 is the stop surface 7231.

[0109] Preferably, the limiting block 723 is provided with a hollow structure (not shown in the drawings), and the hollow structure is arranged close to the stop surface 7231.

[0110] By arranging the hollow structure close to the stop surface 7231, the weight of the lower part of the limiting block 723 is greater than that of the upper part, which is more conducive to closing the air door 72 by its own gravity.
