The connection of spiral case extended segment 13 forms outside air duct 3.
In the present embodiment, the second spiral case extended segment 24 becomes larger from the second spiral case section 23 diameter that extends outwardly.
In the present embodiment, the downside of the second spiral case extended segment 24 is bent to form the second tongue body 25, and in 25 He of the second tongue body
The first wind outlet section 26 is formed between second spiral opening 22.Wherein, the second tongue body 25 extends outwardly from the second spiral case section 23.
It should be noted that the first wind outlet section 26 is almost parallel with the air-out direction in outside air duct 3, this structure design can
With facilitate the air channel structure 1 for and external straight air hose dock, impact of the reduction to straight air hose prevents from shaking.
Figure 10, Figure 11 and Figure 12 are the enlarged drawing in Fig. 9 at X4.Incorporated by reference to 0- Figure 12 referring to Fig.1, in the present embodiment,
Second tongue body 25 includes that connected the second segmental arc 27 and third are obliquely extended section 28.
Second segmental arc 27 extends outwardly setting, also, the second segmental arc 27 and the first segmental arc from the second spiral case section 23
17 are detachably connected.Third is obliquely extended section 28 and is obliquely installed towards the second spiral opening 22, and first is obliquely extended section 18 and
Three, which are obliquely extended section 28, is detachably connected.
In order to adapt to outlet air demand, and guarantee preferable anti-surge and noise reduction effect, in the present embodiment, the second tongue body 25
Horizontal length M is equal with the horizontal length C of the first tongue body 14, and the horizontal length N of the first wind outlet section 26 is equal to the second wind outlet section 16
Horizontal length A and the sum of the horizontal length B of the second volute tongue 7.
As an implementation, the horizontal length M of the second tongue body 25 can be set to 8mm~20mm, the first wind outlet section
