Wherein, the rotational structure also includes impeller protecgulum and magnet holder, passes through between the impeller protecgulum and impeller
Together, and air inlet is arranged at the center drilling of impeller protecgulum ultrasonic fusing；The magnet is fixed by magnet holder
On impeller.
The beneficial effects of the utility model are：Compared with prior art, the rimless outer rotor centrifugation that the utility model is provided
Blower fan, the centrifugal blower only includes rotational structure, fixed structure and the part of crimping structure three, the electricity when DC brushless motor works
Machine impeller is rotated, and impeller produces centrifugal force that air is thrown away from leaf road air outlet when rotated, when the air quilt of Ye Daozhong
After discharge, negative pressure is produced in impeller center, the air outside air inlet, by axial intake impeller, is sucked under atmospheric pressure effect
Air turned back in air inlet and enter leaf road after 90 °.The improvement of said structure, realize centrifugal blower without mount structure, make
The centrifugal blower power obtained in the case where onesize space is taken is higher, because air inlet need not be tightly connected with dustbin, this
Structure design difficulty, the assembling work for also reducing dust catcher or except mite machine are bad, the reliable operation of the centrifugal blower of raising
Property.
