Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing:Shown in Fig. 1-3, one kind described in the utility model
Efficient mute micro-motor flow fan, including frame 1 are provided with wind turbine at the axle center of frame 1, and wind turbine includes and frame 1 is fixed
The stator 3 of connection, the rotor 4 being set on stator 3, and the fan blade 2 that is fixedly installed on 4 circumference of rotor, stator 3 is close to frame
The air intake vent of frame 1, air outlet of the rotor 4 close to frame 1, it is characterised in that be provided with one section among the interior circular channel of the frame
No more than the straight channel 7 of frame thickness half, and it is connected to one section respectively in the both sides of straight channel and extends out channel 8;Positioned at frame
Interior circular channel centre position 4 outer surface of rotor be provided between adjacent fan blade 2 it is several with fan blade 2 with 4 connecting line of rotor
Parallel wind groove 5, the spacing between adjacent wind groove 5 are equal;The outer edge of fan blade air outlet side is provided with raised line 10, described
Raised line 10 is provided with the side 11 being inclined outwardly;The outlet air end of the wind turbine is provided with mute curved surface 12.
As shown in the figure, the stator 3 is located at the air intake vent side of frame 1 and is provided with chamfering 6, and the chamfering 6 of stator 3 is to turning
Son 4 extends to the inlet of wind groove 5;Rotor 4 is located at the outer diameter edge of fan blade 2 and rotor 4 between the end of 1 air outlet of frame
Axial extend to 1 air outlet direction of frame of rotor 4 gradually reduces, and the minimum outer diameter of rotor 4 is not less than the 1/ of maximum outside diameter
2;
Fan blade 2 favours wind turbine and is axially arranged;2 air side of fan blade is provided with flange 9 close to the center of wind turbine;Flange
9 length is not more than the half of 2 length of fan blade;The thickness of flange 9 is not more than 5 times of 2 thickness of fan blade;9 surface of flange is all
Flanging is circular arc chamfering.
When the utility model at work, during exhausting, most of air from the air inlet of 1 axial flow passage of frame into
Enter, air outlet is pushed to by fan blade 2, there is fraction air to be blocked in fan front by stator 3 and form flow-disturbing, there is fraction
Air by after chamfering 6 along 4 outer surface of rotor, by 5 water conservancy diversion of wind groove.Fan blade 2 is in high-speed rotation, by 2 rotation disturbance of fan blade
Air can form a stable high-speed flow in straight channel 7, which can reduce the gas in space between fan blade 2 and frame 1
Pressure so that when the operation of conventional axial-flow fan, the air disturbance at the position is inhaled into air-flow, while the high-speed flow is due to direction
It is identical with 2 rotation direction of fan blade, therefore form lubricant layer between fan blade 2 and frame 1;The wind that pushes away that flange 9 can reinforce fan blade 2 is imitated
Fruit promotes air quantity under same rotational speed.
