Fig. 3 is the circumferential cross-section schematic representation of blade on A-A` of the fan of Fig. 2.
[embodiment]
The present invention is described in detail below in conjunction with drawings and Examples.
Please in the lump referring to Fig. 1 and Fig. 2, Fig. 1 is the front schematic perspective view of fan according to an embodiment of the invention; Fig. 2 is the reverse side schematic perspective view of fan according to an embodiment of the invention.
As depicted in figs. 1 and 2, fan of the present invention mainly comprises wheel hub 1 and in this wheel hub 1 spaced around setting and outward extending a plurality of blades 2.
A plurality of blades 2 comprise first fragment 21 and second fragment 22.First fragment 21 top near this wheel hub on the fan axle direction B of fan is provided with, and this second fragment 22 bottom near this wheel hub on the fan axle direction B of fan is provided with.Referring to Fig. 2 and Fig. 3, an end of first fragment 21 is arranged on this body 12, the outside wing expansion of the other end, and first fragment 21 has from upwardly extending first side 213, the outside side of wheel hub 1 and second side 214; Second fragment 22 has from outside upwardly extending the 3rd side 223 and the four side 224 in side of wheel hub 1.Wherein, second side 214 overlaps with the 3rd side 223, makes win fragment 21 and second fragment 22 form an angle α on circumferential cross-section.
See also Fig. 3, Fig. 3 is the circumferential cross-section figure of blade on A-A` of fan according to an embodiment of the invention.
In the present embodiment, first fragment 21 comprises first windward side 211 and the first relative lee face 212, second fragment 22 comprises that second windward side 221 is connected with angle α bending with second windward side 221 with relative second lee face, 222, the first windward sides 211, and angle α is the obtuse angle.Particularly, on circumferential cross-section, first windward side 211 has first circular arc towards 212 bendings of first lee face, this second windward side 221 has second circular arc towards 222 bendings of second lee face, first circular arc is connected with second circular arc, and the radius of curvature of first circular arc is greater than the radius of curvature of second slyness.It should be noted that the area of this first windward side 211 is greater than the area of this second windward side 221.
In other words, in the present embodiment, blade 2 comprises windward side 211,221 and lee face 212,222, and the windward side 211,221 of blade 2 is the segmented design of bending on circumferential cross-section.Specifically, windward side 211,221 has first circular arc and second circular arc towards lee face 212,222 bendings on circumferential cross-section, first circular arc is near the top of wheel hub, and second circular arc is near the bottom of wheel hub, and the radius of curvature of first circular arc is greater than the radius of curvature of second circular arc.
In addition, in the present embodiment, fan also further comprises the flow-guiding mouth that is arranged on blade 2 lower edges, and specifically comprises near first flow-guiding mouth 23 of body 12 and second flow-guiding mouth 24 away from body 12.Specifically, first flow-guiding mouth 23 is spaced apart near an end and this body 12 of these bodys 12 with second fragment 22, so that gas is via the flowing through of this first flow-guiding mouth 23, thus recycling, and can reduce the resistance that a plurality of blades 2 rotate.Second flow-guiding mouth 24 makes second fragment 22 slightly be shorter than this first fragment 21 away from an end of this body 12, to reduce the resistance of these blade 2 rotations.
In sum, one of ordinary skill in the art will readily recognize that fan of the present invention by the way, make the air quantity of fan and blast reach optimum balance, promote the combination property of fan.And owing to there is the flow-guiding mouth design, reduce the bounce-back of wind, the air-flow that makes water conservancy diversion go out can pass through the blade circulation pressurization of back again, can be recycled to make full use of, and make fan be not easy to produce noise.
In the above-described embodiments, only the present invention has been carried out exemplary description, but those skilled in the art can carry out various modifications to the present invention after reading present patent application under the situation that does not break away from the spirit and scope of the present invention.
