The edge of wind wheel baffle 8 contacts with the inner edge of the side wall of casing 1, and is fixed with casing 1, and baffle protrusion 83 is also arranged on wind wheel baffle 8. Therefore, the wind wheel baffle 8 and the edge of the shell 1 are sealed and airtight, and the airflow formed by ventilation completely passes through the air outlet channel 14. And the wind wheel baffle 8 is also provided with a baffle central hole 82 for airflow to pass through.
The panel 4 is fixed to one end of the housing 1, the panel 4 is provided with an inner concave portion 41, and a panel center hole 42 is formed in the inner concave portion 41. An air inlet cover plate 7 is fixedly arranged at the position of the central hole 42 of the panel; and a gap is arranged between the edge of the air inlet cover plate 7 and the panel, and air is fed; and a gap is formed between the wind wheel baffle 8 and the panel to form a buffer space, so that the noise can be reduced.
In the present embodiment, the panel 4 takes a rectangular shape. The concave portion 41 of the face plate 4 has a truncated cone shape with a larger end and a smaller end. Three first connecting columns 43 are uniformly distributed on the edge of the central hole 42 of the panel, and the first connecting columns 43 are provided with internal threads; the panel 4 is provided with a skirt board 44; the skirt 44 extends in the same direction as the direction in which the inner recess 41 protrudes.
