Embodiment 1
[0079] Such as Figure 7 As shown, in addition to the features of the above-mentioned embodiments, it is further defined that: the air duct 130 includes a volute 132 and a volute tongue 133, and the wind guide surface of the volute tongue 133 is arranged opposite to the wind guide surface of the volute 132 and defines a first For the curved section 1311 , in detail, the wind guiding surface of the volute tongue 133 provides a first convex surface, and the wind guiding surface of the volute 132 provides a second concave surface. The first curved section 1311 is defined by a convex and a concave surface. In this way, the compatibility between the first curved section 1311 and the wind wheel or fan 300 can be improved, and the requirements for wind pressure control and airflow smoothing can be better met.
[0080] Of course, the first curved section 1311 defined by the volute 132 and the volute tongue 133 is a preferred embodiment of this design. In other embodiments, those skill...
Embodiment 2
[0082] Such as Figure 7 As shown, in addition to the characteristics of the above-mentioned embodiment 1, it is further defined that: the air duct 130 also includes an air guide wall 134, the air guide surface of the air guide wall 134 is concave arc-shaped, and the air guide surface of the air guide wall 134 is in line with the The wind guide surface of the volute tongue 133 is transitionally connected; the end of the volute 132 adjacent to the outlet 136 is provided with a tongue 135, and the wind guide surface of the tongue 135 is opposite to the wind guide surface of the wind guide wall 134, so that the wind guide wall 134 and the protrusion The tongue 135 defines the second curved section 1312. In detail, the wind guiding surface of the tongue 135 provides a second convex surface, and the wind guiding surface of the wind guiding wall 134 provides a first concave surface. The second curve segment 1312 . In this way, the transition smoothness between the first curve secti...
Embodiment 3
[0086] Such as Figure 7 As shown, in addition to the features of the above-mentioned embodiment 2, it is further defined that the wind guiding surface of the tongue 135 is formed as a convex arc surface. This helps to ensure the smoothness of the airflow on the air guide surface of the tongue 135, reduces the resistance loss of the airflow at the tongue 135, and is not easy to form a back pressure at the position where the tongue 135 is adjacent to the outlet 136, which is conducive to reducing the noise of the airflow .
