Abstract
A kind of blade structure of fan, including blade and wheel hub；The blade is located at hub surface；The hub surface is obliquely installed, it is characterised in that：The blade is equipped with 8, and each blade is symmetrically and annular is uniformly distributed；The wheel hub is tapered hood-like；The hub surface is gradually tapered up from edge to center；The section of the wheel hub is trapezoidal；The hub surface and the angle c of central axis are 30 ° 45 °.In the utility model, the wheel hub (35 degree of preferably best angles with central shaft) of taper cover shape makes wind warp be dissipated later toward surrounding pressure, windage is small.Arc-shaped wind cutting side (55 degree preferably best angles with trunnion axis), can reach that wind cutting is suitable, presses the good effect of wind；Cause air quantity in this smooth transition in the arc-shaped pressure air blade foot of wind cutting edge tail.
Description
Technical field
The utility model is related to a kind of fan, the blade structure of specifically a kind of fan.
Background technology
Existing leaf blade often has the shortcomings that wind cutting effect is bad, and the pressure air blade foot of wind cutting on piece is with cutting
Wind side cannot prepare well, enable smooth excessive of air quantity.
A kind of fan blade as disclosed in Chinese patent literature CN105240317A 13 days January in 2016, including wheel hub and
Distribution is fixed on several flabellum ontologies of the wheel hub；The flabellum ontology is divided into front end face, rear end face, along before direction of rotation
Side, rear side and outside, the outside are the end that the flabellum ontology is radially extended along the wheel hub；The outside is equipped with interior
Folding part, the inflexed part from the outside along perpendicular to the flabellum ontology end face direction to front end face side bent
Into.
Therefore, it is further improved.
Utility model content
The purpose of this utility model is intended to provide a kind of simple and reasonable, and wind cutting is suitable, pressure wind works well, and is not in
The blade structure of choke, to overcome deficiency of the prior art.
By a kind of blade structure of fan of this purpose design, including blade and wheel hub；The blade is located at hub surface；
The hub surface is obliquely installed, and the blade is equipped with 8, and each blade is symmetrically and annular is uniformly distributed；The wheel hub is in
Taper is hood-like；The hub surface is gradually tapered up from edge to center；The section of the wheel hub is trapezoidal；The wheel hub table
The angle c of face and central axis is 30 ° -45 °.
The c is 35 °；The front of the wheel hub is arc surface.
Wind cutting side is equipped in the wind cutting side of the blade；The wind cutting side is extended internally by the edge of wheel hub, and in circle
Arc is set.
The angle a of the wind cutting side and wheel hub horizontal axis is 40 ° -75 °.
The angle a is 55 °.
The wind cutting edge tail is arc-shaped pressure air blade foot；The folder of the pressure air blade foot and wheel hub horizontal axis
Angle b is less than angle a.
The utility model is primarily adapted for use in hair dryer, the hood-like wheel hub of taper (35 degree of preferably best angles with central shaft),
Wind warp is made to be dissipated later toward surrounding pressure, windage is small.Arc-shaped wind cutting side (55 degree of preferably best angles with trunnion axis) is set, it is reachable
To wind cutting it is suitable, pressure the good effect of wind；Cause air quantity in this smooth transition in the arc-shaped pressure air blade foot of wind cutting edge tail.

Specific embodiment
Referring to Fig. 1-Fig. 7, a kind of blade structure of fan is primarily adapted for use in hair dryer, including blade 1 and wheel hub 2；Leaf
Piece 1 is located at 2 surface of wheel hub；2 surface of wheel hub is obliquely installed, and blade 1 is equipped with 8, and each blade 1 is symmetrically and annular is uniformly distributed；Wheel
Hub 2 is tapered hood-like；2 surface of wheel hub is gradually tapered up from edge to center；The section of wheel hub 2 is trapezoidal；2 surface of wheel hub and center
The angle c of axis is 30 ° -45 °.
Further, c is preferably 35 °；The front of the wheel hub is arc surface.
Further, it is equipped with wind cutting side 1.1 in the wind cutting side of blade 1；Wind cutting side 1.1 is inside by the edge of wheel hub 2
Extension, and it is arc-shaped setting.
Further, the angle a of wind cutting side 1.1 and 2 horizontal axis of wheel hub is 40 ° -75 °.
Further, angle a is preferably 55 °.
Further, 1.1 end of wind cutting side is arc-shaped pressure air blade foot 1.2；Press air blade foot 1.2 and 2 water of wheel hub
The angle b of flat axis is less than angle a.
The basic principle, main feature of the utility model has been shown and described in the above-mentioned preferred embodiment for the utility model
And the advantages of the utility model.Those skilled in the art should be recognized that the present utility model is not limited to the above embodiments, on
