[detailed description of the invention]
Below in conjunction with drawings and Examples, the present invention is described in detail.
Please also refer to Fig. 1 and Fig. 2, Fig. 1 is the front solid of fan according to an embodiment of the inventionSchematic diagram; 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 around this wheel hub 1Interval arranges and outward extending multiple blades 2.
Wheel hub 1 is for assembling fixing fan, and wheel hub 1 further comprises top cover 11, body 12. TopCover 11 roundedly, be positioned at the top of this wheel hub 1. If the fixing assembling of fan is to be coordinated by top cover 11, top cover 11 centers can be provided with circular hole 111 (referring to Fig. 2), for strengthening the fixing dress of this fanJoin. Body 12 is cylindric and is vertically installed in this top cover 11 edges, multiple blades 2 intervals arrange withOn this body 12, it should be noted that multiple blades 2 also have the rib that extends to top cover 11215, can be used for strengthening the mechanical strength of fan.
Multiple blades 2 comprise the first fragment 21 and the second fragment 22. The first fragment 21 is at the fan of fanThe upper top near this wheel hub of direction of principal axis B arranges, and this second fragment 22 is on the fan direction of principal axis B of fanBottom near this wheel hub arranges. Referring to Fig. 2 and Fig. 3, one end of the first fragment 21 is arranged at this pipeOn body 12, the outside wing expansion of the other end, the first fragment 21 has on the direction outside from wheel hub 1First side 213 and the second side 214 of extending; The second fragment 22 has outside from wheel hub 1Upwardly extending the 3rd side 223 and the four side 224 in side. Wherein, second side 214 and the 3rd sideLimit 223 overlaps, and makes the first fragment 21 and the second fragment 22 shape in the circumferential cross-section α that has angle.
Refer to Fig. 3, Fig. 3 be the blade of fan according to an embodiment of the invention on A-A` circumferentiallySectional view.
In the present embodiment, the first fragment 21 comprises the first windward side 211 and relative the first lee face212, the second fragments 22 comprise that the second windward side 221 and relative the second lee face 222, the first are windwardFace 211 is connected with angle α bending with the second windward side 221, and angle α is obtuse angle. Particularly,In circumferential cross-section, the first windward side 211 has the first circular arc towards the first lee face 212 bendings,This second windward side 221 has the second circular arc towards the second lee face 222 bendings, the first circular arc andTwo circular arcs are connected, and the radius of curvature of the first circular arc is greater than the second round and smooth radius of curvature. Merit attention,, 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 comprise windward side 211,221 and lee face 212,222, the windward side 211,221 of blade 2 is the segmented design of bending in circumferential cross-section. Concrete nextSay, windward side 211,221 has the first circle towards lee face 212,222 bendings in circumferential cross-sectionArc and the second circular arc, the first circular arc is near the top of wheel hub, and the second circular arc is near the bottom of wheel hub, andThe radius of curvature of the first circular arc is greater than the radius of curvature of the 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 comprise near the first flow-guiding mouth 23 of body 12 and the second flow-guiding mouth 24 away from body 12.Specifically, the first flow-guiding mouth 23 by the second fragment 22 one end and this body 12 near this body 12Spaced apart, so that gas is via the flowing through of this first flow-guiding mouth 23, thereby recycle, and can reduceThe resistance that multiple blades 2 rotate. The second flow-guiding mouth 24 makes the second fragment 22 away from this body 12One end is slightly shorter than this first fragment 21, the resistance rotating to reduce this blade 2.
In sum, one of ordinary skill in the art will readily recognize that fan of the present invention by the way, makeThe air quantity and the blast that obtain fan reach optimum balance, promote the combination property of fan. And because existence is ledHead piece design, reduces the bounce-back of wind, and the air-flow that water conservancy diversion goes out can be pressurizeed by blade circulation below again,Can be recycled and make full use of, and make fan be not easy to produce noise.
In the above-described embodiments, only the present invention is carried out to exemplary description, but those skilled in the artCan be without departing from the spirit and scope of the present invention to the present invention after reading present patent applicationCarry out various amendments.
