Embodiment 1 please refers to shown in Fig. 1-Fig. 5, and the present embodiment provides a kind of axial-flow leafs, including：Wheel hub 1 and several edges
The blade 2 being circumferentially provided on wheel hub 1, each blade 2 all have the leading edge 21, outer rim 22 and trailing edge 23 being sequentially connected, outer rim
It is α that 22 two-end-points, which are in line as first straight line, first straight line and the first plane angle, wherein the first plane and wheel hub 1
Axis it is vertical, 20 °≤α≤35 °.
The axial-flow leaf that the present embodiment is obtained by above-mentioned design is optimized by the structure to blade 2, makes outer rim 22
It is α that two-end-point, which is in line with the plane angle perpendicular to 1 axis of wheel hub, and makes 20 °≤α≤35 °.To make axis stream wind
The air-out effect for the air-supply air-flow that leaf generates more is stablized, and the problem of radial diffusion is less likely to occur.Meanwhile the present embodiment carries
The axial-flow leaf of confession can realize reverse outlet air when reversely rotating, and outlet air airflow stability is more preferably when reverse outlet air.
Further, Fig. 4 is please referred to, in the present embodiment, 21 °≤α≤26 °.It is highly preferred that α=23.7 °.Make axis stream
The air-out effect for the air-supply air-flow that fan blade generates achievees the effect that radial direction that is more stable, while occurring as far as possible compared with little airflow
Diffusion.
Further, Fig. 1 and Fig. 5 are please referred to, in the present embodiment, wheel hub 1 is cylindric, and the quantity of blade 2 is three,
On the peripheral surface of three 2 spaced sets of blade and wheel hub 1, and the maximum outside diameter φ B of the diameter phi A of wheel hub 1 and axial-flow leaf
Ratio be 1/9-1/11.By the optimization of the ratio between 2 width of 1 diameter of wheel hub and blade, make the workmanship efficiency of blade 2
It obtains optimization to be promoted, increases air output while ensureing the stability of air-supply.Preferably, the diameter phi A of wheel hub 1 and axis stream wind
The ratio of the maximum outside diameter φ B of leaf is 1/10.The air output of bigger can be obtained while ensureing the stability of air-supply by realizing.
Further, Fig. 1 and Fig. 3 are please referred to, in the present embodiment, wheel hub 1 has opposite front end face and rear end face, after
End face is equipped with the first muscle slot 13, and rotating shaft connecting structure 12 is equipped in the first muscle slot 13, and rotating shaft connecting structure 12 is screw hole.Work as axis
When stream fan blade is connect with motor, motor is located at the rear end face side of wheel hub 1.The front end face of wheel hub 1 is plane, referred to as plane
Side, front end face are equipped with several through-holes 11, and each through-hole 11 is connected to the first muscle slot 13.
Existing axial-flow leaf is typically all muscle slot to be arranged on wheel hub end face facing forward, and motor and wheel hub are backwards
End face connects.In this way, when axial-flow leaf rotates, muscle slot can generate interference to air-supply air-flow, influence the steady of air-flow of blowing
It is qualitative.In the present embodiment, the first muscle slot 13, which is arranged, to be made on rear end face, that is, by the first muscle slot 13 towards motor side
For axial-flow leaf in rotation, the first muscle slot 13 will not generate interference to air-supply air-flow, further increase the stability of air-supply air-flow.
The equipment such as air conditioner at runtime, are understood and generate liquid near axial-flow leaf, by front end face in the present embodiment
Through-hole 11 is set, prevents liquid accumulation in the first muscle slot 13, influences the normal rotation of axial-flow leaf.
Further, Fig. 4 is please referred to, in the present embodiment, the tail end of blade 2 exceeds rear end face a distance of wheel hub 1.
Specifically, distance of the trailing edge 23 far from 22 one end of outer rim to the rear end face of wheel hub 1 is L1, and leading edge 21 is connect with 1 peripheral surface of wheel hub
The distance of rear end face of one end to wheel hub 1 be the ratio of L2, LI and L2 be 0.35-0.55.Make axial-flow leaf in air-supply, gas
Stream can avoid open wheel hub 1, to reduce influence of the wheel hub 1 to air-flow of blowing, further increase the stability of air-supply air-flow.It is excellent
The ratio of selection of land, LI and L2 are 0.42-0.45.Further decrease influence of the wheel hub 1 to air-flow of blowing.
Further, please refer to Fig. 1-Fig. 3, in the present embodiment, blade 2 also have inner edge 24, one end of inner edge 24 with
One end of 23 principle outer rim 22 of trailing edge connects, and the other end of inner edge 24 is connect with the peripheral surface of wheel hub 1, and inner edge 24 and wheel hub 1
Peripheral surface between be equipped with the second muscle slot 25.Due to blade 2 tail end exceed wheel hub 1 rear end face a distance, can make blade 2 with
1 connective stability of wheel hub reduces, by the way that the second muscle slot 25 is arranged between 1 peripheral surface of inner edge 24 and wheel hub, increase blade 2 with
Stability between wheel hub 1 avoids axial-flow leaf in rotation, and blade 2 shakes, to influence the stability of air-supply air-flow.
Further, Fig. 1 is please referred to, to further increase the connective stability of blade 2 and wheel hub 1, in the present embodiment,
Blade 2 has opposite the first face and the second face, and the first face is equipped with rib 26, and rib 26 extends to the peripheral surface of wheel hub 1.
Rib 26 is extended to the peripheral surface of wheel hub 1 by the first face of blade 2, when can avoid blade 2 and rotating, since the influence of air pressure is to the
The direction in two faces tilts to influence the stability of air-supply air-flow.Meanwhile rib 26 has certain thickness, with 2 turns of blade
When dynamic, can also certain stabilization be played to air-supply air-flow, further increase the stability of air-supply air-flow.
The present embodiment also provides a kind of axial flow blower, including fan blade, and fan blade is the axial-flow leaf of any of the above-described.This implementation
The air-out effect for the air-supply air-flow that the axial flow blower that example provides generates more is stablized, and the problem of radial diffusion is less likely to occur.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
