And the fan blade in rotor circumference is fixedly installed on, stator is close to the air intake vent of framework, and for rotor close to the air outlet of framework, it is special
Levy and be to be provided with one section of straight channel for being not more than frame thickness half among the interior circular channel of the framework, and in straight channel
Internal face is provided with the shallow chute of spiral shape of a few road parallel arrangements, is connected to one section respectively in the both sides of straight channel and extends out passage；
The air intake vent side that described stator is located at framework is provided with chamfering.
As preferred：If the rotor outer surface positioned at the interior circular channel centre position of framework is provided between adjacent fan blade
The dry wind groove parallel with rotor connecting line with fan blade, the spacing between adjacent wind groove are equal；The chamfering of stator extends to rotor
The porch of wind groove；Rotor is located at the external diameter of fan blade and rotor between the termination of framework air outlet along rotor axially to frame
The extension of frame air outlet direction gradually reduces, and the minimum outer diameter of rotor is not less than the 1/2 of maximum outside diameter；
It is axially arranged that fan blade favours blower fan；Fan blade air side is provided with flange close to the center of blower fan；The length of flange
No more than the half of fan blade length；The thickness of flange is not more than 5 times of fan blade thickness；All flangings in flange surface are circular arc
Shape chamfering.
The invention belongs to improvements over the prior art, it has rational in infrastructure, compact, and cost is low, have higher rotating speed and
Power, and it is small to generate heat, the features such as air quantity is big.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Shown in Fig. 1-3, one kind of the present invention is high-power micro-
Motor axial fan, including framework 1, blower fan is provided with the axle center of framework 1, and blower fan includes the stator being fixedly connected with framework 1
（3）, the rotor 4 that is arranged on stator 3, and the fan blade 2 being fixedly installed on the circumference of rotor 4, stator 3 enter close to framework 1
Air port, air outlet of the rotor 4 close to framework 1, it is characterised in that be provided with one section among the interior circular channel of the framework and be not more than
The straight channel 7 of frame thickness half, and the internal face of straight channel is provided with the shallow chute of spiral shape of several roads parallel arrangement, straight
The both sides of passage are connected to one section and extend out passage 8 respectively；The air intake vent side that described stator 3 is located at framework 1 is provided with chamfering
6。
Shown in figure, it is provided with positioned at the outer surface of rotor 4 in the interior circular channel centre position of framework between adjacent fan blade 2
Some wind grooves 5 parallel with the connecting line of rotor 4 with fan blade 2, the spacing between adjacent wind groove 5 are equal；The chamfering 6 of stator 3 to turn
Son 4 extends to the porch of wind groove 5；Rotor 4 is located at the external diameter edge of fan blade 2 and rotor 4 between the termination of the air outlet of framework 1
Rotor 4 axially gradually reduces to the extension of the air outlet direction of framework 1, and the minimum outer diameter of rotor 4 is not less than the 1/ of maximum outside diameter
2；
It is axially arranged that fan blade 2 favours blower fan；The air side of fan blade 2 is provided with flange 9 close to the center of blower fan；Flange 9
Length is not more than the half of the length of fan blade 2；The thickness of flange 9 is not more than 5 times of the thickness of fan blade 2；All flangings in the surface of flange 9
It is circular arc chamfering.
At work, during exhausting, most of air passes through fan blade 2 to the present invention from the axial flow passage air inlet of framework 1
Air outlet is pushed to, has fraction air to be blocked in fan front by stator 3 and forms flow-disturbing, have fraction air to pass through chamfering 6
Afterwards along the outer surface of rotor 4, by the water conservancy diversion of wind groove 5.For fan blade 2 in high-speed rotation, the air by the rotation disturbance of fan blade 2 can be in straight channel
One stable high velocity air of interior formation, the air-flow can reduce the air pressure in space between fan blade 2 and framework 1 so that conventional axial flow
During the operation of fan, the air disturbance at the position is inhaled into air-flow, while the high velocity air is due to direction and the rotation direction of fan blade 2
It is identical, therefore form lubricating layer between fan blade 2 and framework 1；What flange 9 can strengthen fan blade 2 pushes away wind effect, under same rotational speed
Lift air quantity.
