According to described major technique feature, described flabellum outer periphery is equipped with the motor base inner ring for parcel flabellum and motor.

According to described major technique feature, the end face of described motor one end is provided with a plurality of spiral helicine heliconids, and this heliconid is positioned at an end of motor base inside.

According to described major technique feature, described controller module comprises the controller, the delay circuit plate that is arranged at controller inside that are arranged at the motor base side, be arranged at the power supply lid above the controller and be used for the power supply lid is fixed in a plurality of screws above the controller.

According to described major technique feature, described exhaust outlet shell or intake grill shell are respectively to be made of the annulus housing that has step.

According to described major technique feature, described iron hoop or intake grill inner ring are respectively to be that the buckling of shells of spill forms circle body and constitutes by the cross section.

The beneficial effects of the utility model: because described motor case comprises exhaust outlet shell, the iron hoop that is arranged at exhaust outlet shell end face that is arranged at the motor base outlet air end, the intake grill inner ring that is arranged at the intake grill shell of motor base intake grill end and is arranged at intake grill shell end face.During use, because described motor case is assembled by exhaust outlet shell, iron hoop, intake grill shell and intake grill inner ring respectively, be conducive to whole motor case assembly and disassembly, install and the purpose of convenient disassembly thereby reach.Simultaneously, in use for some time, be conducive to clean each part or the parts of motor case inside, therefore reach and clean purpose easily.End face because of described motor one end is provided with a plurality of spiral helicine heliconids again, and this heliconid is positioned at a motor base inner end.When the straight line air channel that steam flow is formed by intake grill shell, intake grill inner ring and motor base inner ring, steam flow blows the spiral air port that forms toward motor base internal spiral body by the fan blade supercharging again in this straight line air channel, supercharging uses blast to promote again again, improving wind speed blows toward exhaust outlet, make to form the low steam flow of high blast noise, therefore reach the low purpose of the big noise of blast.

Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
