Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Shown in Fig. 1-3, a kind of high efficiency of the present invention is 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 being arranged on stator 3, and the fan blade 2 being fixedly installed on the circumference of rotor 4, inlet air of the stator 3 close to framework 1
Mouthful, air outlet of the rotor 4 close to framework 1, it is characterised in that one section is provided among the interior circular channel of the framework and is not more than frame
The straight channel 7 of frame thickness half, the internal face of straight channel is provided with the shallow chute of spiral shape that several roads are arranged parallel to, and
The both sides of straight channel are connected to one section and extend out passage 8 with arc surface transition respectively；Positioned at the interior circular channel centre position of framework
The outer surface of rotor 4 some wind grooves 5 parallel with the connecting line of rotor 4 with fan blade 2, adjacent wind are provided between adjacent fan blade 2
Spacing between groove 5 is equal.
Shown in figure, the air intake vent side that described stator 3 is located at framework 1 is provided with chamfering 6, and the chamfering 6 of stator 3 is to turning
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 to the present invention from the air inlet of the axial flow passage of framework 1
2 are pushed to air outlet, have fraction air to be blocked in fan front by stator 3 and form 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 direct current
A stable high velocity air is formed in road 7, the air-flow can reduce the air pressure in space between fan blade 2 and framework 1 so that tradition
During the operation of aerofoil fan, the air disturbance at the position is inhaled into air-flow, while the high velocity air is due to 2 turns of direction and fan blade
Dynamic direction is identical, therefore forms lubricating layer between fan blade 2 and framework 1.What flange 9 can strengthen fan blade 2 pushes away wind effect, in phase
With lifting air quantity under rotating speed.
