Abstract
The utility model discloses a fan blade. The fan blade is characterized in that the fan blade comprises inner and outer rings of fan blades which are located in a same axle center, and the outer ring fan blades are located on the outer side of the inner ring fan blades. During usage, a large amount of air can be drawn by the outer ring fan blades, wind can be concentrated and sent out through the inner ring fan blades, by means of the design, the wind which is sent out is concentrated and violent, the wind can be naturally scattered beyond a certain distance, an air blow range of the fan blade is larger than that of a prior fan, and the fan blade has a good popularizing value.
Description
Technical field
The utility model relates to the fan technical field, relates to a kind of electric fan structure more specifically.
Background technique
Electric fan is called for short electric fan, is a kind of motoring flabellum rotation that utilizes, and reaches the household electric appliance that make air quicken circulation, is mainly used in cooling and heatstroke-eliminating and ventilating air, is widely used in family, office, shop, hospital and hotels and other places.Electric fan mainly is made up of parts such as fan head, flabellum, guard and control gear.At present, common electric fan flabellum is made up of three blades, quaterfoil or six blades, and vanes fixed is isogonism and distributes on same rotating disk, and flabellum is driven by the fan head, reaches the purpose that makes air quicken circulation.Like one Chinese patent application number is CN200610033428.1; Denomination of invention is a combined type fan flabellum with low noise; Comprise: wheel wheel and equi-spaced apart are arranged on the linear leaf on its periphery, it is characterized in that: the sheet end around linear leaf is connected with and its all-in-one-piece basic ring; The basic ring internal ring wall at each linear leaf interval be provided with at least one facing the wind curved surface towards with the corresponding to short blade of linear leaf.The flabellum of this patent structure is compared with the conventional monolayers flabellum under same rotational speed and air quantity situation, and noise reduction is very obvious, but the flabellum air supplying distance is short, and wind-force disperses, and the air blast scope is little.
Summary of the invention
The purpose of the utility model is exactly provide for the deficiency that solves existing technology a kind of not only simple in structure, easy to install, and the electric fan that wind-force is soft, the air blast scope is wide.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of electric fan is characterized in that it comprises the Internal and external cycle flabellum that is positioned on the same axle center; The outer ring flabellum is positioned at the inner ring flabellum outside, and the outer ring flabellum at first is involved in a large amount of air, through the inner ring flabellum wind is concentrated then and is seen off; At this moment; Wind is very concentrated fierce, can scatter by nature but crossed a segment distance after wind, thereby obtains the air blast scope than fan was bigger in the past.
As further specifying of such scheme: the outer rim of said inner ring flabellum is provided with wheel hub, and the middle part of inner ring flabellum is provided with and holds the axis hole that rotating shaft is passed.
Preferably, said inner ring flabellum tilts to be connected between axis hole sidewall and the wheel hub, and the inner ring flabellum is made up of the blade more than three, and the quantity of blade can be decided according to the actual requirements, be traditionally arranged to be 5 proper.
Said outer ring flabellum is connected on the wheel hub.
Preferably, said outer ring flabellum is made up of the blade more than three, leaves between the blade of adjacent two outer ring flabellums at interval, and the quantity of blade can be decided according to the actual requirements, be traditionally arranged to be 9 proper.
The blade of said outer ring flabellum is the quadrilateral blade, and blade lean is arranged on the outside of wheel hub.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model also adopts the flabellum design of inside and outside two circles except increasing electric fan, the outer ring flabellum at first is involved in a large amount of air; Through the inner ring flabellum wind is concentrated then and seen off, at this moment, wind is very concentrated fierce; Can scatter by nature but crossed a segment distance after wind, thereby obtain, and compare with fan in the past more in the past than the air blast scope that fan was bigger; The wind that is caused is more evenly soft, has also effectively avoided the picture the sort of sound that is similar to cutting in the past, and noise is littler.

Embodiment
As shown in Figure 1, a kind of electric fan of the utility model, it comprises the Internal and external cycle flabellum 1,2 that is positioned on the same axle center, outer ring flabellum 2 is positioned at inner ring flabellum 1 outside.The outer rim of inner ring flabellum 1 is provided with wheel hub 3; The middle part of inner ring flabellum 1 is provided with and holds the axis hole 4 that rotating shaft is passed; Outer ring flabellum 2 is made up of the blade more than three; Leave between the blade of adjacent two outer ring flabellums at interval, the quantity of blade can be decided according to the actual requirements, be traditionally arranged to be 9 proper.The quadrilateral that the blade of outer ring flabellum 2 is, blade lean are arranged on the outside of wheel hub 3.In the present embodiment, inner ring flabellum 1 tilts to be connected between axis hole sidewall and the wheel hub, and inner ring flabellum 1 is made up of the blade more than three, and the quantity of blade can be decided according to the actual requirements, be traditionally arranged to be 5 proper.
The utility model is except increasing electric fan; Also adopt the flabellum design of inside and outside two circles, the outer ring flabellum at first is involved in a large amount of air, through the inner ring flabellum wind is concentrated then and is seen off; At this moment; Wind is very concentrated fierce, can scatter by nature but crossed a segment distance after wind, thereby obtains the air blast scope than fan was bigger in the past.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
