Abstract
The invention discloses a kind of bionical preparation blades, including wheel hub and single blade;The single blade is made of root, stage casing and endpiece;Wherein, the thickness of the root and the endpiece is more than the thickness in the stage casing, to which the stage casing region forms the groove of the flexible pile of attachment in the single blade.A kind of bionical preparation blade of the present invention uses for reference birds assistant shape, and face of blade, the back side, corner are all made of cambered design, to reduce friction, to the air drag being subject to when reducing blade movement to the maximum extent.Flexible pile (or other flexible materials) is adhered in the single blade surface of the present invention using means are inlayed, and can adsorb noise, further decrease wind and make an uproar.
Description
Technical field
The invention belongs to fluid machinery technical fields, and in particular to a kind of fan part, especially a kind of bionical inlay are answered
Hing straps.
Background technology
Variously-shaped blade used in country's rotary fan at present, when operating generally existing wind make an uproar big, air-supply away from
From short problem.
Most thickness is uniform in design for these blades, does not also change on radian, this structure design makes fan not
Only wind is made an uproar greatly and air supplying distance is limited;In addition, all fans do not inlay the flexible napped material of attachment in blade surface, in addition
Most of blade weight counterbalances are uneven, to generate prodigious vibration when fan rotates, cause wind to be made an uproar high.
It is that the fan blade rotated generates when rubbing with air that wind, which is made an uproar,.Wind, which is made an uproar, can make us feeling not quite the thing, especially
It is that sense of discomfort is even more serious when fan is continuously run for a long time.
Therefore, state's intra vane manufacturer and terminal user are badly in need of a kind of wind and make an uproar that smaller, air supplying distance is farther at present
Leaf product.
Invention content
The purpose of the present invention is to reduce fan wind to make an uproar and increase fan air-supply distance, it is proposed that a kind of bionical to inlay
Composite blading uses for reference birds assistant shape, can reduce the air drag being subject to when blade movement to the maximum extent.
The present invention provides a kind of bionical preparation blades, including wheel hub and single blade;The single blade by root, in
Section and endpiece composition;Wherein, the thickness of the root and the endpiece is more than the thickness in the stage casing, in the single blade
The upper stage casing region forms the groove of the flexible pile of attachment.
The endpiece periphery is made of several curved surfaces;Along the root outwardly direction, several curved surfaces form one
Tip, the direction of the tip are opposite with the direction of rotation of the blade.
The direction of rotation of the contour line and the blade of a curved surface in several curved surfaces is tangent.
The periphery in the root and the stage casing is made of curved surface.
The upper curved surface of the single blade is generally bent downwardly.
The both sides curved surface of the single blade is generally bent to away from direction of rotation.
Along the hub radius outwardly direction, the root and the stage casing are gradually upturned along curve, and in institute
Endpiece is stated to be bent gradually downward along curve.
The root, the stage casing and the endpiece are integrally formed.
The periphery of the wheel hub is equipped with the groove that can be embedded in the root.
The root is fastened on by welding or by screw on the wheel hub.
There are one the through-holes that can be inserted in rotary shaft for the wheel hub center tool.
Compared with prior art, a kind of bionical preparation blade of the invention uses for reference birds assistant shape, and blade is just
Face, the back side, corner are all made of cambered design, to reduce friction, to the air being subject to when reducing blade movement to the maximum extent
Resistance;It is designed using 3D and changes traditional blades structure, keep blade weight counterbalance more accurate, further decreased and generate when blade movement
Vibration achievees the purpose that drop low wind noise.
Flexible pile (or other flexible materials) is adhered in the single blade surface of the present invention using means are inlayed, can be with
Noise is adsorbed, wind is further decreased and makes an uproar.
The present invention also makes air-supply more concentrate the improvement of fan balde structure, is not easy to spread simultaneously, to effectively increase
Air supplying distance.
In addition, blade material is using high molecular materials or light-weight metals such as TPEE elastomeric materials or ABS, PA, PP, PC
Material effectively reduces the energy consumption of fan electromotor to mitigate leaf weight, improves fan effect.

Specific implementation mode
Present invention is further described in detail below in conjunction with the accompanying drawings:
The present invention provides a kind of bionical preparation blades, including wheel hub 1 and single blade 2;The single blade 2 is by root
3, stage casing 4 and endpiece 5 form;Wherein, the thickness of the root 3 and the endpiece 5 is more than the thickness in the stage casing 4, thus
4 region of the stage casing forms the groove of the flexible pile of attachment in the single blade 2.
5 periphery of the endpiece is made of several curved surfaces;Along 3 outwardly direction of the root, several curved surfaces form one
A tip, the direction of the tip are opposite with the direction of rotation of the blade.
The direction of rotation of the contour line and the blade of a curved surface in several curved surfaces is tangent.
The periphery in the root 3 and the stage casing 4 is made of curved surface.
The upper curved surface of the single blade 2 is generally bent downwardly.The quantity of the single blade is singular piece, it is preferable that such as
Fig. 1 show 7.
The both sides curved surface of the single blade 2 is generally bent to away from direction of rotation.
Along 1 radius outwardly direction of the wheel hub, the root 3 and the stage casing 4 are gradually upturned along curve, and
The endpiece 5 is bent gradually downward along curve.
The root 3, the stage casing 4 and the endpiece 5 are integrally formed.
The periphery of the wheel hub 1 is equipped with the groove that can be embedded in the root 3.
The root 3 is fastened on by welding or by screw on the wheel hub 1.
There are one the through-holes that can be inserted in rotary shaft for 1 center tool of the wheel hub.
Flexible pile (or other flexible materials) is adhered in 2 surface of single blade of the present invention using means are inlayed, can
To adsorb noise, further decreases wind and make an uproar.
The present invention also makes air-supply more concentrate the improvement of fan balde structure, is not easy to spread simultaneously, to effectively increase
Air supplying distance.
Noise test the result shows that, under conditions of identical size, same rotational speed, bionical preparation blade compares conventional leaf
Piece lower noise 52% (is shown in Table 1).Due to the special construction of blade, air supplying distance also increases to 10 meters by 5 meters of common blade
(it is shown in Table 2) above.
