Wherein, be provided with the first screw that is connected with wheel hub on the sleeve.
The lightweight blades are plastic blades or aluminum alloy blades.
Wherein the number of the light blades is 36-42.
And two ends of the connecting rod are respectively welded and fixed with the second turntable and the sleeve.
And second screws connected with the first rotating disc are arranged on the hub in an array manner.
Wherein, the front of the second turntable is provided with an air inlet ring extending forwards.
Wherein, the second carousel openly is provided with the fresh air inlet that is located the air inlet circle inboard.
The utility model has the beneficial effects that: the utility model provides a lightweight air supply impeller subassembly has adopted the lightweight blade very much, when increasing quantity, reduces the dead weight, is favorable to promoting the air supply volume, carries out the spacing at lightweight blade both ends through first positioning groove and second positioning groove moreover, and the dismouting is convenient, and single lightweight blade can quick replacement after damaging, has promoted and has maintained the convenience.
