Embodiment
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
The present invention discloses a kind of fan, comprise housing, exhaust apparatus and flabellum and motor, as fan embodiment one of the present invention, as shown in Figure 1 to Figure 3, described flabellum and motor are arranged in the housing, housing is provided with intake grill, exhaust apparatus is arranged on case top, exhaust apparatus is provided with exhaust outlet 3, described exhaust outlet 3 is arranged on the exhaust apparatus rear end, and exhaust outlet 3 front portions are provided with the acclive protuberance 11 of tool, be provided with the air channel between exhaust apparatus and the housing, thereby the wind that the flabellum rotation produces in the housing is transported in the exhaust apparatus by the air channel and blows out from exhaust outlet 3, and by protuberance 11, because protuberance 11 has certain gradient, thereby wind just blows out along protuberance 11, wind in the fan is in the process that blow at protuberance 11 places, and the wind around the wind that blows out in the fan just drives blows out forward by exhaust apparatus together, thereby has increased the air quantity of fan.
In the present embodiment, described exhaust apparatus comprises air-out inner casing 1 and air-out shell 2, described air-out inner casing 1 is arranged in the air-out shell 2, described protuberance 11 is arranged on air-out inner casing 1 rear end, described exhaust outlet 3 is between described air-out inner casing 1 and air-out shell 2, and exhaust apparatus arranges air-out inner casing 1 and air-out shell 2, thereby conveniently sets out air port 3, air-out passage thereon and swell 11, thereby saved the production time, saved cost; In addition, the air-out inner casing 1 in exhaust outlet 3 front portions arranges the acclive protuberance 11 of tool, can make the wind that blows out drive ambient air and flow, thereby increase air quantity; Because protuberance 11 is set, and then the diameter of described air-out inner casing 1 reduces to described protuberance 11 centers gradually from its afterbody, thereby make things convenient for the wind in the exhaust apparatus to blow out from exhaust outlet 3 uniformly.Angle between described protuberance 11 and the horizontal plane is acute angle, and the angle that 11 tops itself form of namely swelling is the obtuse angle, thereby guarantees that the wind energy in the fan enough blows out forward smoothly.End, described air-out shell 2 rear end cooperates described protuberance 11 to be provided with forward turnover 21, described turnover 21 has the identical gradient with protuberance 11, described exhaust outlet 3 is at described protuberance 11 and turn down between 21, air-out shell 2 cooperates protuberance 11 that the described exhaust outlet 3 of formation is set, thereby when blowing out at protuberance 11 places, the wind in the fan blows out along protuberance 11 and turnover 21, because protuberance 11 has the identical gradient with turnover 21, namely turn down 21 and protuberance 11 be arranged in parallel, thereby can make from turn down 21 and protuberance 11 wind that blow out reach optimum efficiency.Certainly, in the present embodiment, be not limited to turnover and the protuberance rear end be arranged in parallel, also can be arranged to other structures, as long as it is just passable to guarantee that exhaust outlet can go out wind smoothly.
In order to guarantee the size of exhaust outlet 3, namely guarantee turnover 21 and the maintaining a certain distance between 11 of swelling, thereby smoothly the wind in the fan is blown out from exhaust outlet 3, be provided with the uniform strip bulge (not shown) of air-out direction at turnover 21 internal surfaces, thereby strip bulge can guarantee to turn down 21 and swell that 11 rear ends are parallel to make air-out reach the optimum state as far as possible.In the present embodiment, also can be provided with the uniform strip bulge of air-out direction in protuberance 11 back end outer surface of air-out inner casing 1, can play identical effect.
In the present embodiment, air-out passage in the described exhaust apparatus is ring, described exhaust outlet 3 also is ring, described exhaust outlet 3 and air-out passage are communicated with, air-out passage and exhaust outlet 3 all are arranged to ring, go out in the process in wind, make the wind that blows out even, stable, and it is maximum that cirque structure is compared other structures shared volume under equal volume, thereby can increase the area of fan blowing.Thereby described air-out inner casing 1 is made as round structure, convenient production, the diameter of described air-out inner casing 1 increases gradually forward from described protuberance 11 and ends at front end, and the diameter at termination air-out inner casing 1 is constant, the air-out inner casing continues to extend forward, so just form the constant part of a bit of diameter, then, diameter increases gradually more forward and changes larger, in air-out inner casing 1 front end end, the relative air-out inner casing of the vary in diameter of air-out inner casing 11 middle part changes greatly, so just can further increase the zone that fan blows to.This is a kind of concrete structure that air-out inner casing 1 is set, and setting can increase the area of fan blowing like this.Certainly, also air-out inner casing 1 can be arranged to other structures.Described air-out inner casing 1 front end end is provided with outside inner casing turnover 12, be provided with on the corresponding air-out shell 2 and the described inner casing turnover 12 recessed seams 22 that cooperate, arrange like this and make things convenient between air-out inner casing 1 and the air-out shell 2 fixingly, but also can guarantee the surface smoothness of air-out shell 2.In the present embodiment, described air-out inner casing 1 turns down 12 places at inner casing and is bonded on the air-out shell 2 by glue, thereby air-out inner casing 1 and air-out shell 2 are fixed together.
In the present embodiment, the area that the area that described turnover 21 tops surround surrounds greater than protuberance 11 tops, arrange like this to turn down 21 just carried out spacing, protuberance 11 tops are given prominence to outside turnover 21, thereby flow before driving rear portion and wind direction on every side when making things convenient for the interior wind of fan to blow out at protuberance 11 places, thereby guarantee that the wind that fan blows out has larger air quantity.
Difference with embodiment one is as fan embodiment two of the present invention, described exhaust apparatus is wholely set, and the inner cavity that forms annular is air-out passage, and an exhaust outlet for air-out is set in the exhaust apparatus rear end, described exhaust outlet and described cavity are communicated with, thereby can realize blowing.Described exhaust outlet front portion is provided with the acclive protuberance of tool, in the front portion, slit that is used for blowing the acclive protuberance of tool is set, and can make the wind that blows out drive ambient air and flow, thereby increase air quantity.Other settings are identical with embodiment one with beneficial effect, tell about no longer one by one here.
Difference with embodiment one is as fan embodiment three of the present invention, described air-out passage is set to square, described exhaust outlet also is set to square, described exhaust outlet and air-out passage are communicated with, this is the another kind of structure that sets out air port and air-out passage, other settings are identical with embodiment one with beneficial effect, tell about no longer one by one here.
Exhaust apparatus of the present invention not merely is limited on cirque structure and the square structure, also can be arranged to other structures, as long as can realize that the effect without the leaf blowing all is feasible; Such as exhaust apparatus is arranged triangular structure, can realize equally the effect without the leaf blowing.
Above content is the further description of the present invention being done in conjunction with concrete preferred implementation, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
