Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Mode, the present invention will be further described in detail.
Referring to figs. 1 to Fig. 5, the utility model first embodiment provides a kind of wind turbine, and the wind turbine can be used for lung ventilator.
Including spiral case 1, the spiral case has air intake vent 11 and air outlet 12, is equipped in spiral case 1 from air intake vent 11 axially inwardly successively
The impeller 2 and motor 3 of setting；The impeller 2 includes the multiple blades 21 for being evenly distributed on its axis, and the blade 21 has
There is the second end of motor 3 described in the first end and face of air intake vent 11 described in face；The motor 3 is external rotor electric machine,
Include the magnetic steel sleeve 31 coaxial with the impeller 2, the magnetic steel sleeve 31 is equipped with multiple recessed correspondingly with the blade 21
Slot 311,311 structure of the groove are matched with 21 second end structure of the blade, for plugging 21 second end of the blade
End.
It should be noted that the size of the groove 311 is slightly larger than the size of 21 second end of the blade, so that
21 second end of blade can be more easily plugged in the groove 311.
Further, the distance between the groove 311 and blade 21 are not more than h/2, and the h is vane thickness.We
Case can be further reduced the leakage of gas.
It should be noted that all having the gap as air duct between two adjacent blades.Impeller was rotating
Cheng Zhong, air flow into from spiral case air intake vent, are flowed out from spiral case air outlet again by interlobate gap.
The wind turbine of this programme during the installation process, blade second end is inserted into the groove of magnetic steel sleeve so that impeller
It is rotated synchronously with magnetic steel sleeve, the load of impeller will not be increased；In addition vortex damage of the gas between impeller and motor is also reduced
It loses, improves blower pressure and flow.
Further, the impeller 2 is rear half-opened impeller, further includes front shroud 22, the front shroud 22 and the leaf
21 first end of piece piece connects, and the front shroud 22 is equipped with perforative ventilation hole 221, enters described in 221 face of the ventilation hole
Air port 11.Air is pumped into ventilation hole by the impeller of this programme from air intake vent, then flow to spiral case air outlet through interlobate gap, is had
Effect reduces the eddy current loss between blade first end and spiral case.
