Description
Technical field
The utility model relates to household electrical appliance technical field, and particularly a kind of electric fan relates in particular to a kind of compound flabellum of electric fan and the electric fan that comprises this compound flabellum.
Background technique
Ke Xuejishu tremendous development in recent years makes people's living standard have and significantly improves.In order to hide hot summer, air-conditioning has entered common people house already.That but electric fan has is cheap, little power consumption, promptly buy promptly with, move the incomparable advantages of many air-conditionings such as convenient, thereby great market is arranged still, and this market is with long-term existence.
The technology of electric fan is just ripe a long time ago, but science is endless, and people also are endless to the pursuit of the good things of life Sino-U.S..Electric fan in those early years in order to protect flabellum, simultaneously also for fear of danger, all is provided with the flabellum safety cover in electric fan flabellum periphery because flabellum all is hard, and the guard that this kind flabellum safety cover is normally made by metallic material is almost stereotyped in appearance.And the complex manufacturing technology of metal guard, also not corrosion-resistant, the plastic cement guard of outward appearance novelty has appearred in the therefore near section time.The plastic cement guard has a lot of incomparable advantages of metal guard, thereby beginning is more and more adopted.But the Security of plastic cement guard is less than the metal guard, especially some electric fan is apparent attractive in appearance in order to pursue, and guard has been carried out too much simplification, makes people's hand or other bigger object can both touch flabellum, thereby dangerous, be necessary to improve.
The model utility content
Technical problem to be solved in the utility model provides a kind of compound flabellum, and it is safer, and can not reduce the efficient of electric fan.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of compound flabellum comprises soft soft leaf layer, also comprise with described soft leaf stacked together, the sclerophyll layer that quality is harder; The size of described sclerophyll layer is less than the size of soft leaf layer, makes that the edge of compound flabellum had only soft leaf layer when described sclerophyll layer and soft leaf were laminated together to form described compound flabellum.
Another technical problem to be solved in the utility model provides a kind of electric fan, and it is safer, and efficient is also higher.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of electric fan comprises compound flabellum, and described compound flabellum comprises soft soft leaf layer, also comprise with described soft leaf stacked together, the sclerophyll layer that quality is harder; The size of described sclerophyll layer is less than the size of soft leaf layer, makes that the edge of compound flabellum had only soft leaf layer when described sclerophyll layer and soft leaf were laminated together to form described compound flabellum.
In the optimized technical scheme, described soft leaf layer has two-layer, is respectively the first soft leaf layer and the second soft leaf layer, and accompanies described sclerophyll layer between the described first soft leaf layer and the second soft leaf layer.
The beneficial effects of the utility model are:
Owing to adopted soft leaf layer and sclerophyll to be laminated together to form the compound flabellum of composite structure, and the edge of compound flabellum has only soft soft leaf layer, so both guaranteed the Security of the compound flabellum of high speed rotating, also guaranteed the working efficiency of electric fan.
Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 3 is the structural representation after the compound flabellum of the utility model embodiment is taken the surperficial soft leaf layer of one deck off.
Fig. 4 is the structural representation that dissects of the compound flabellum of the utility model embodiment.
Fig. 5 is the partial enlarged drawing of A part among Fig. 4.
Embodiment
This embodiment mainly is to realize by the improvement to flabellum to the improvement of existing plastic cement guard electric fan.As seen from Figure 1, the compound flabellum 1 in this embodiment seems the same with general flabellum in appearance, roughly be the flaky texture with certain curved surface, and the one end is provided with plural mounting hole 10; It is softer just feeling the edge that will find this compound flabellum 1.
By Fig. 2 Fig. 4 in conjunction with Fig. 5 as seen, this compound flabellum 1 is to comprise three parts that stack, and is respectively: first soft leaf layer 11, second soft leaf layer 12 and the sclerophyll layer 13.The shape of the first soft leaf layer 11 and the second soft leaf layer 12 and measure-alike wherein, and make by soft EVA (abbreviation of Ethylene-vinyl acetate copolymer ethylene-vinyl acetate copolymer) plastics, thickness is approximately 1.5 millimeters.And sclerophyll layer 13 adopts the harder PP plastics of quality to make, and thickness is approximately 0.5 millimeter.And as seen from Figure 3, key is that the size of sclerophyll layer 13 is less than the first soft leaf layer 11 and the second soft leaf layer 12, so that the three stacks when forming compound flabellum 1, the edge of compound flabellum 1 has only the soft leaf layer of EVA material, and does not have the harder sclerophyll layer 13 of quality; Even make people's hand run into the compound flabellum 1 of high speed rotating, can be not dangerous yet.Because the existence of sclerophyll layer 13 has been arranged, make main body (centre) part of compound flabellum 1 have better hardness, compare soft flabellum with sclerophyll layer 13, the efficient of electric fan can be higher.If there is not sclerophyll layer 13, though compound flabellum 1 is safe, because integral hardness is not enough, the efficient of electric fan can obviously reduce.
Can adopt Placements such as bonding, ultrasonic welding, silk suture even closing-up to connect between the described first soft leaf layer 11, sclerophyll layer 13 and the second soft leaf layer 12, as long as can make triplicity become the compound flabellum 1 of an integral body, in the actual production, preferred glue is bonding, and perhaps two sided plaster is bonding.
The first soft leaf layer 11 and the second soft leaf layer 12 are provided with three corresponding mounting holes 10, and have only two mounting holes on the sclerophyll layer 13.In the mounting hole 10 on the position of the mounting hole 10 on the sclerophyll layer 13 and size and the first soft leaf layer 11 and/or the second soft leaf layer 12 two are corresponding.
Need to prove that aforementioned description to first soft leaf layer 11, the second soft leaf layer 12 and sclerophyll layer 13 thickness is only for exemplifying, in the actual product, the thickness of the first soft leaf layer, the second soft leaf layer can be between 0.5 to 5 millimeter, between preferred 1 to 2 millimeter; And the thickness of sclerophyll layer 13 can be between 0.2 to 3 millimeter, between preferred 0.3 to 2 millimeter.
Need to prove that also compound flabellum 1 can have only the soft leaf layer of one deck and one deck sclerophyll layer to form, and also can reach the effect that needs substantially, but the sandwich structure that aforementioned three stacks is preferred compound blade structure.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
