Embodiment
Below in conjunction with accompanying drawing, preferably embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 4, this example provides a kind of electric fan of combined type, comprise: wheel hub 1 and at least a slice flabellum, described flabellum comprises the first flabellum 2, connecting tendon 3 and the second flabellum 4, one end of described first flabellum 2 is connected with wheel hub 1 edge, and the other end of described first flabellum 2 is connected with the second flabellum 4 by connecting tendon 3; Minimum constructive height difference between described first flabellum 2 and the second flabellum 4 is 2mm ~ 8mm.
Fig. 1 is the main TV structure schematic diagram of this example; Fig. 2 is the perspective view of this example, and also title waits axis side view; Fig. 3 is this routine right TV structure schematic diagram; Fig. 4 is the cross-sectional view along A-A ' direction in Fig. 1; With respect to the horizontal plane, between described first flabellum 2 of this example and the second flabellum 4, there is height difference, as shown in Figure 2 and Figure 4, between described first flabellum 2 of this example and the second flabellum 4, belong to staggered floor design; If the minimum constructive height difference between described first flabellum 2 and the second flabellum 4 is too large, will make comparatively to disperse wind-force; If the minimum constructive height difference between described first flabellum 2 and the second flabellum 4 is too little, resistance will be made to strengthen, stricter to the requirement of power; The experiment proved that, minimum constructive height difference between described first flabellum 2 of this example and the second flabellum 4 is 2mm ~ 8mm, while resistance when as far as possible can reduce gap between the first flabellum 2 and the second flabellum 4, increases air quantity, reduce noise, substantially increase the effect of fan.
Described first flabellum 2 of this example, connecting tendon 3 and the second flabellum 4 are integrally formed shaping flabellum; Connected by 2 ~ 5 connecting tendons 3 between described first flabellum 2 and the second flabellum 4, preferably, connected by 3 connecting tendons 3 between described first flabellum 2 and the second flabellum 4, ensure that the stability of electric fan.
This routine described connecting tendon 3 respectively with the first flabellum 2 and the second flabellum 4 perpendicular, described first flabellum 2 and the second flabellum 4 are parallel to each other; Or there is the first angle between described first flabellum 2 and the second flabellum 4, the angle of described first angle is 0 ° ~ 45 °, namely the angle angle on the first flabellum 2 between the tangent plane of arbitrfary point and this tangent plane selecting Normal direction and the second flabellum 4 crosspoint is between 0 ° ~ 45 °, feature like this can guide the flow direction of wind further, and then again reduce fluid by the resistance between the first flabellum 2 and the second flabellum 4 during gap, increase air quantity, reduce noise, and strengthen radiating effect.
Described first flabellum 2 of this example is provided with breach 5 near one end of the second flabellum 4, and described second flabellum 4 is connected to by connecting tendon 3 on the breach 5 of the first flabellum 2; Preferably, the shape of described second flabellum 4 is consistent with the shape of breach 5, and the size of described second flabellum 4 is less than or equal to the size of breach 5, such setting, the resistance of electric fan can be made less, be beneficial to Design of Dies simultaneously.
As shown in Figure 3, there is the second angle in the connecting line between described first flabellum 2 of this example and wheel hub 1 and wheel hub 1 axle center, the angle of described second angle is preferably 70 ° ~ 110 °; The angle of described second angle and the angle of the first angle cooperatively interact, and can play guiding function, and then enhance the efficiency of fan, reduce noise to the flow direction of wind.
The embodiment of the above is better embodiment of the present utility model; not limit concrete practical range of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence change that all shapes according to the utility model, structure are done is all in protection domain of the present utility model.
