Preferably, described spiral case outer fixing is provided with support, and described motor is arranged on the described support.
Preferably, offer intake grill on the described spiral case, the plane at the plane at described intake grill place and described exhaust outlet place is perpendicular.
Further preferred, described intake grill place is provided with slip ring, its by described spiral case outward in the described spiral case direction comprise outer end, middle-end, the inner successively, the sectional area of setting described outer end is that the sectional area of S1, described middle-end is S2, the sectional area of described the inner is S3, S1＞S3＞S2.
Preferably, described impeller comprises back plate, guide plate, is fixedly installed on the multi-disc blade between described back plate and the described guide plate, described blade is the arc shaped blade with arc outlet air surface, it comprises the front portion near the rear portion of the gyration center of described impeller, close described wheel rim, to described anterior the extension, the radian of described arc shaped blade increases described blade gradually by described rear portion.
Further preferred, described guide plate is horn-like, and it comprises first port and second port, and the sectional area of described first port is greater than the sectional area of described second port, and described vanes fixed is connected described first port.
Further preferred, described back plate is a surface plate.
Further preferred, the wheel rim place of the close described impeller of a side that is connected with described guide plate of described blade has salient angle.
Further preferred, the radian increment rate at described rear portion is less than the radian increment rate of described front portion.
Further preferred, described blade welds fixing with described guide plate, described blade and described back plate mutually.
Because technique scheme utilization, the present invention compared with prior art has following advantage: because the present invention adopts the spiral case of sub-circular, make its compact structure, thereby realization miniaturization, and because the present invention adopts two exhaust outlet designs, can make impeller in operation process, increase pressure and air inflow, make airflow field more evenly smooth and easy, thereby reduced noise.
