Abstract
A fan blade comprises a cylindrical hub, a plurality of blades and a plurality of centrifugal blades. A motor shaft hole is arranged on the cylindrical hub, the cylindrical hub is hollow and is provided with a rear opening, a motor shaft hole is dispose don a top plate of the cylindrical hub, the centrifugal blades are disposed on the inner surface of the top plate of the cylindrical hub, and an air outlet hole which is communicated with the wall of the cylindrical hub is arranged on the cylindrical hub and positioned between each two adjacent blades. Due to the structure, air enters the cylindrical hub via the rear opening of the cylindrical hub, and is exhausted via the air outlet holes on the wall of the cylindrical hub under the effects of the centrifugal blades in the cylindrical hub, the blades act on the air exhausted via the air outlet holes, and the speed of the air is increased. Compared with an axial flow blade in the prior art, the fan blade has the advantage that the air volume and the air exhaust speed are increased under the condition of identical power.
Description
Technical field
The present invention relates to the fan blade that a kind of fan is used.
Background technique
Present existing technology, a kind of fan blade of fan comprises centric leaf hub and several blades, on the said centric leaf hub motor axis hole is arranged.Existing problems are: when fan needed big air output, motor speed was high, and noise is big.
Summary of the invention
The objective of the invention is: a kind of fan blade of fan is provided, compared with prior art, under the identical situation of power, can increases wind speed effectively, increase air output, and noise is little.
The present invention is achieved in that a kind of fan blade of fan, comprises centric leaf hub and several blades, on the said centric leaf hub motor axis hole is arranged, and its special way is: have after-opening in vain in the said centric leaf hub, its top board has motor axis hole;
Also comprise some centrifugal blades, said centrifugal blade is arranged on the internal surface of top board of centric leaf hub;
The exhaust vent that connects centric leaf hub wall is arranged on the centric leaf hub between adjacent two blades.
The fan blade of said a kind of fan, its special way is: the diameter of the circular trace that said centrifugal blade radially inner side end constitutes is to the diameter greater than motor.
The fan blade of said a kind of fan, its special way is: the diameter of the circular trace that said centrifugal blade outboard end constitutes is less than the diameter of the inner chamber of cylinder table shape leaf hub.
The fan blade of said a kind of fan, its special way is: said centrifugal blade along the height of the axial direction of centric leaf hub less than height along centric leaf hub axial direction.
The fan blade of said a kind of fan, its special way is: said centrifugal blade equals the height of centric leaf hub axial direction along the height of the axial direction of centric leaf hub.
The fan blade of a kind of fan of the present invention is owing to adopt this spline structure, the after-opening air intake of centric leaf hub; In the centric leaf hub under the effect of centrifugation blade; Discharge the exhaust vent from centric leaf hub wall, blade acts on the wind that exhaust vent is discharged, thereby has accelerated wind speed; Compare with axial-flow leaf of the prior art, under the identical situation of power, increase air output and air-out speed.

Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1, a kind of fan blade of fan comprises centric leaf hub 1 and several blades 2, on the said centric leaf hub 1 motor axis hole is arranged, and has after-opening in vain in the said centric leaf hub 1, and its top board 11 has motor axis hole 12;
Also comprise some centrifugal blades 3, said centrifugal blade 3 is arranged on the internal surface of top board 11 of centric leaf hub 1;
The exhaust vent 4 that connects centric leaf hub 1 wall is arranged on the centric leaf hub 1 between adjacent two blades 2.
The diameter of the circular trace 31 that said centrifugal blade 3 radially inner side ends constitute is to the diameter greater than motor 5.The diameter of the circular trace 32 that centrifugal blade 3 radial outside ends constitute is less than the diameter of centric leaf hub 1 inner chamber.Described here radially is with centric leaf hub 1 is reference.
Said centrifugal blade 3 along the height of the axial direction of centric leaf hub 1 less than height along centric leaf hub 1 axial direction.
It also can be said centrifugal blade 3 equals centric leaf hub 1 axial direction along the height of the axial direction of centric leaf hub 1 height.
Above-described only is preferential mode of execution of the present invention.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the principle of the invention, can also make some improvement and modification, this also is regarded as protection scope of the present invention.
