Description
Technical field
The utility model relates to a kind of blower fan, relates in particular to the adjustable blower fan of a kind of air output.
Background technique
Blower fan is the abbreviation to gas compression and gas conveying machinery, and usually said blower fan comprises ventilator, blower, wind-driven generator.Gas compression and gas conveying machinery are that the mechanical energy of rotation is converted to gas pressure energy and kinetic energy, and the machinery that gas is transferred out.
The air-flow that above-mentioned blower fan is carried can be used for being dried, ventilation, cooling etc.For desiccant blower fan, it is unadjustable that blower fan delivers into the air quantity of drying room, thereby affected the dry uniformity.
For the problems referred to above, be necessary to propose further solution.
Model utility content
The purpose of this utility model is to provide a kind of blower fan.
For realizing above-mentioned model utility object, a kind of blower fan of the present utility model, it comprises: casing, impeller, intake grill, exhaust outlet, venetian blind; Described impeller is installed in described casing, described intake grill is opened in a side of described casing, and be connected with described casing by air intake pipe, described exhaust outlet is opened in the opposite side of described casing, and be connected with described casing by wind pipe, in the wind pipe between described exhaust outlet and described casing, be also provided with venetian blind.
As further improvement of the utility model, described venetian blind comprises some flabellums that are arranged in parallel.
As further improvement of the utility model, described intake grill is horn mouth.
As further improvement of the utility model, the quantity of described exhaust outlet is two, and described two exhaust outlets separate and arrange, and are connected with described wind pipe respectively.
As further improvement of the utility model, described casing below is provided with base.
Compared with prior art, the beneficial effects of the utility model are: blower fan structure of the present utility model is simple, and it,, by venetian blind is set in air channel, can regulate by this venetian blind the air quantity that enters drying room accurately, has ensured the dry uniformity.
Brief description of the drawings
Fig. 1 is the floor map of an embodiment of blower fan of the present utility model.
Embodiment
Below in conjunction with each mode of execution shown in the drawings, the utility model is elaborated; but should be noted that; these mode of executions are not limitation of the utility model; those of ordinary skill in the art are according to these mode of execution institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection domain of the present utility model.
As shown in Figure 1, blower fan 100 of the present utility model comprises: casing 10, impeller, intake grill 20, exhaust outlet 30, venetian blind 40.Wherein, described impeller is installed in the space that described casing 10 limits, and impeller is installed on impeller shaft, and impeller shaft is rotated by the driving of motor.When impeller shaft rotation, impeller rotates thereupon, thereby realizes the conveying of air.Described intake grill 20 is opened in a side of described casing 10, and is connected with described casing 10 by air intake pipe 11, and described exhaust outlet 30 is opened in the opposite side of described casing 10, and is connected with described casing 10 by wind pipe 12.Thereby in the time of fan operation, air enters into air intake pipe from intake grill, and by casing, wind pipe, discharge from exhaust outlet, realize the conveying of air.
Preferably, described intake grill 20 is horn mouth, thereby is convenient to entering of air.The quantity of described exhaust outlet 30 is two, and described two exhaust outlets 30 separate and arrange, and are connected with described wind pipe 12 respectively.
Further, in the wind pipe 12 between described exhaust outlet 20 and described casing 10, be also provided with described venetian blind.This venetian blind 40 comprises some flabellums that are arranged in parallel.By the large I of spacing changing between each flabellum, the conveying air quantity of blower fan is regulated.
In addition, described casing 10 belows are provided with base.
In sum, blower fan structure of the present utility model is simple, and it,, by venetian blind is set in air channel, can regulate by this venetian blind the air quantity that enters drying room accurately, has ensured the dry uniformity.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any reference character in claim should be considered as limiting related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme in each embodiment also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
