Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
The utility model discloses a kind of fan, comprise housing, go out wind apparatus and flabellum and motor, as fan embodiment one described in the utility model, as shown in Figure 1 to Figure 3, described flabellum and motor are arranged in the housing, housing is provided with intake grill, go out wind apparatus and be arranged on case top, go out wind apparatus and be provided with exhaust outlet 3, described exhaust outlet 3 is arranged on out the wind apparatus rear end, and exhaust outlet 3 front portions are provided with the protuberance 11 with gradient, go out between wind apparatus and the housing and be provided with the air channel, thereby the wind that the flabellum rotation produces in the housing is transported to out in the wind 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 going out wind apparatus together, thereby has increased the air quantity of fan.
In the present embodiment, describedly go out wind apparatus and comprise 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 goes out wind apparatus and sets out wind inner casing 1 and air-out shell 2 between described 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 protuberance 11 with gradient is set on the air-out inner casing 1 of exhaust outlet 3 front portions, can makes the wind that blows out drive ambient air and flow, thereby increase air quantity; Because protuberance 11 is set, and the diameter of then described air-out inner casing 1 reduces to described protuberance 11 centers gradually from its afterbody, thereby the wind that conveniently goes out in the wind apparatus blows out from exhaust outlet 3 uniformly.Angle between described protuberance 11 and the horizontal plane is an acute angle, and the angle that 11 tops itself form of promptly 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, promptly 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 protuberance rear end are 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, just guarantee the 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 on protuberance 11 back end outer surface of air-out inner casing 1, be provided with the uniform strip bulge of air-out direction, can play identical effect.
In the present embodiment, the described air-out passage that goes out in the wind apparatus is a ring, described exhaust outlet 3 also is a ring, described exhaust outlet 3 and air-out channel connection, air-out passage and exhaust outlet 3 all are arranged to ring, go out in the process, make the wind that blows out even, stable in wind, and cirque structure is compared other structures shared volume maximum 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 bigger, 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, the zone that so just can further increase fan and blowed 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, corresponding air-out shell 2 is provided with and the described inner casing turnover 12 recessed seams 22 that cooperate, be provided with 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, be provided with 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, thereby guarantee that the wind that fan blows out has bigger air quantity at protuberance 11 places.
Difference with embodiment one is as fan embodiment two described in the utility model, describedly go out wind apparatus and be wholely set, the inner cavity that forms annular is the air-out passage, one exhaust outlet that is used for air-out is set going out the wind 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 protuberance with gradient, and the anterior protuberance with gradient that is provided with in the slit that is used to dry can make the wind that blows out drive ambient air and flow, thereby increase air quantity.
Difference with embodiment one is as fan embodiment three described in the utility model, described air-out passage is set to square, described exhaust outlet also is set to square, described exhaust outlet and air-out channel connection, this is the another kind of structure that sets out air port and air-out passage, other settings are identical with beneficial effect, tell about no longer one by one here.
Of the present utility modelly going out wind apparatus and not merely be limited on cirque structure and the square structure, also can be arranged to other structures, all is feasible as long as can realize not having the effect of leaf blowing; Such as going out wind apparatus triangular structure is set, can realizes not having the effect of leaf blowing equally.
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.
