Abstract
Provided is a novel fan blade structure. The end of blade tip of each fan blade is provided with an arc-shaped limp. The arc-shaped limp which is opposite to a fan blade body and an axial has an angle of inclination. By means of utilizing the novel fan blade structure, area and acting force of the fan blade can be increased and pressure output neighbouring the blade tip of the fan blade can be enhanced, so that temperature and airflow discharging velocity is reduced, energy-saving effects is greatly improved and work efficiency is improved. The structure of the novel fan blade structure is simple and air pressure and blowing rate generated by the fan blade is bigger when the fan blade works. The novel fan blade structure has the advantages that noise is small, friction is small, and no deviation and vibration occur when rotating and the like.
Description
Technical field
The utility model relates to a kind of flabellum, more particularly relates to a kind of structure of flabellum.
Background technique
Existing electric fan comprises a wheel hub and is positioned at most blades of wheel hub periphery, and its Leaf the inner is individually fixed on the excircle of wheel hub, arranges radially centered by wheel hub, and when work, blade rotary drives surrounding atmosphere and flows, and produces air-flow.In order to promote the working efficiency of flabellum, prior art is improved mostly and is set about from changing the modes such as flabellum quantity and fan frame mechanism or increase rotation speed of the fan, to increasing air output and air output, take this improving heat radiation efficiency, follow this air quantity to increase and the rotation speed of the fan raising, cause fan in the running, large quantity of air and flabellum collide rapidly, rub, and produce the running noise that wind is cut sound, therefore affect the water conservancy diversion effect of fan.
The model utility content
The utility model proposes a kind of blade structure, solved the large problem of existing technology noise in the prior art.
The technical solution of the utility model is achieved in that
The utility model blade structure comprises wheel hub and fan blade axle sleeve, and wheel hub periphery extended loop is wound with the flabellum blade that multi-disc is radial arrangement, and each flabellum blade tip end is provided with an arc limb.
Further, the relative flabellum of described arc limb is radially axially inclined with flabellum.
The first stiffening rib that annular further, is arranged between described flabellum end of blade and the flabellum body.
Further, become a mandarin limit or go out to flow the second stiffening rib is arranged between limit and the wheel hub of described flabellum body.
Further, described fan blade, wheel hub and fan blade axle sleeve are integrated formed structures.
The beneficial effects of the utility model: adopt technique scheme, increase the active force of fan blade area and flabellum, improve near the Output pressure of flabellum end of blade, reducing the flabellum wind-engaging tangentially affects, when having improved working efficiency, reduce noise and friction, promote degree of stability, reach best water conservancy diversion effect, and then reduce noise.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is an embodiment's of the utility model structure plan view;
Fig. 2 is an embodiment's of the utility model structure side view;
Fig. 3 is an embodiment's of the utility model structure schematic perspective view;
1 is blade among the figure, and 2 is wheel hub, and 3 is fan blade axle sleeve, and 4 is the arc limb, and 5 is the first stiffening rib, and 6 is the second stiffening rib.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one:
See also shown in accompanying drawing 1 and 2, the novel blade structure of the present embodiment is wheel hub 2 and the fan blade axle sleeve 3 that comprises multi-disc blade 1, and wheel hub 2 periphery extended loops are wound with the flabellum blade 1 that multi-disc is radial arrangement, and each flabellum blade tip end is provided with an arc limb 4.Arc limb 4 and the flabellum 1 body concentric of flabellum 1 blade tip end are basic identical with flabellum 1 turning radius cylindrical at the appearance profile line of axial direction projection.Arc limb 4 launches with approximate involute pattern, in the use state, almost only produces surface friction drag, can change the intake of air-flow, thereby changes the action effect of the novel flabellum of the present embodiment.Relative flabellum 1 body of the arc limb of each flabellum 2 blade tip end reaches axially certain angle of inclination, and air-flow only has surface friction drag to the active force that limb 4 produces, and does not have the resistance loss of limb, has increased the influx of air-flow.The first stiffening rib 5 that is provided with annular between flabellum 1 and the flabellum limb 4 couples together flabellum 1 and flabellum limb 4, and the first stiffening rib 5 improves the shape stability of flabellum 1, has guaranteed flabellum 1 structural strength.Flabellum 1 body become a mandarin the limit or go out to flow the limit and wheel hub 2 between be provided with the shape stability that the second stiffening rib 6, the second stiffening ribs 6 improve flabellums 1, guaranteed flabellum 1 structural strength.Fan blade 1 in the present embodiment, wheel hub 2 and fan blade axle sleeve 3 be the one forging forming in a mould.Make other structures of the present embodiment referring to prior art.
Embodiment two:
Be the supplementary notes to last embodiment, the shape of the first stiffening rib 5, position and quantity are determined according to the requirement of blade structure intensity.The shape of the second stiffening rib 6, position and quantity are determined according to the requirement of blade structure intensity, can flabellum 1 go out to flow the limit and the limit that becomes a mandarin, Yi Bian perhaps wherein be provided with stiffening rib.Fan blade 1, wheel hub 2 and fan blade axle sleeve 3 also can be integrally manufactured by forging type, also can make respectively assembling.Other structures of the present embodiment are with embodiment one.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
