Embodiment
See also Fig. 1 and Fig. 2, in a preferred embodiment of the present invention, a combination of fans comprises a fixed mount 20, a fan 30 and a protective cover 40.
Described fixed mount 20 comprises a top board 21, a base plate 23, two relative side plate 25 and ventilation front plates 27.In one embodiment, described top board 21 parallel described base plates 23, and vertical described side plate 25 and ventilation front plate 27, described side plate 25 vertical described ventilation front plates 27.Described top board 21, base plate 23, biside plate 25 form one in order to accommodate the receiving space of described fan 30 and described protective cover 40 with described ventilation front plate 27.Four jiaos of places of described ventilation front plate 27 offer respectively one first fixing hole 271.
Corresponding described first fixing hole 271 in four jiaos of places of described fan 30 is respectively equipped with one second fixing hole 31, and is provided with an air outlet 33.
Described protective cover 40 comprises an antetheca 41 and the roof 42, a diapire 43 and the two relative sidewalls 45 that extend from four edges of described antetheca 41.In one embodiment, described roof 42 parallel described diapires 43, described roof 42 and sidewall 45 vertical described antethecas 41.Described antetheca 41 is offered an opening 418.A square unfilled corner is established respectively in the intersection of the two ends of described roof 42 and described two side 45, thereby forms an installation sheet 401 and a stop tab 403, and two drift angles 413 of described antetheca 41 are relative with square unfilled corner.In one embodiment, described installation sheet 401 vertical described roof 42 and described stop tab 403, described stop tab 403 parallel described roofs 42, described opening 418 is circular open, and roughly the same with air outlet 33 sizes, the size of described fan 30.Described installation sheet 401 is offered one first pivoting hole 4011.Each drift angle 413 is offered one first installing hole 4131.Each sidewall 45 is offered some the second pivoting holes 451.
Another unfilled corner is established respectively in the intersection of the two ends of described diapire 43 and described two side 45, thereby forms respectively a stator 405 that tilts, and two base angles 415 of described antetheca 41 are relative with unfilled corner.Angle between each stator 405 and the described diapire 43 is the obtuse angle.Extend some banking stops 453 on the inwall of each sidewall 45 and stator 405.Also be provided with two catch 4051 on the inwall of each stator 405, described two catch 4051 are parallel to each other, and near described antetheca 41.In one embodiment, the described roof 42 of described banking stop 453 and catch 4051 almost parallels.One second installing hole 4151 is offered at each base angle 415.All install a pivotal axis 46 between described two first pivoting holes 4011, per two second pivoting holes 451.
Fix respectively a blade 47 on each pivotal axis 46, wherein a blade 47 is between two described installation sheets 401, and some blades 47 are between two described sidewalls 45, and two blades 47 are between two described stators 405.Each blade 47 comprises that respectively one is fixed on fixed part 471 and the free section 473 on the pivotal axis 46, and described fixed part 471 is fixed on the pivotal axis 46.Be installed between described two installation sheets 401 and four blades 47 that are installed between the described two side 45 all are roughly rectangular lamellar body, two blades 47 that are installed between described two stators 405 are roughly trapezoidal lamellar body.Each blade 47 can rotate with corresponding pivotal axis 46, and each blade 47 comprises one first side 475 and one second side 476; In two neighbouring blades 47, the second side 476 of the free section 473 of top blade 47 is pressed on first side 475 of fixed part 471 of lower leaflet 47, and these blades 47 cover opening 418.Be installed on the blade 47 between described two stop tab 403 and be installed on blade 47 between described two stators 405 compared to the blade 47 that is installed between the described two side 45, have height about equally, but have less area.
Please consult simultaneously Fig. 3 to Fig. 5, during assembling, described fan 30 is packed in the receiving space of described fixed mount 20, and described the first fixing hole 271 of described the second fixing hole 31 alignment.Towards described fan 30, mobile described protective cover 40 is until a side of described protective cover 40 and described fan 30 leans with the antetheca 41 of described protective cover 40.At this moment, described protective cover 40 is housed in the receiving space of described fixed mount 20, and the second fixing hole 31 of described the first installing hole 4131 and the described fan 30 of the second installing hole 4151 alignment.Utilize the locking part such as screw to pass described the first fixing hole 271 and the second fixing hole 31, with described fan 30 lockings in described fixed mount 20.Described protective cover 40 can utilize the locking parts such as screw or rivet to pass the first installing hole 4131 of described the second fixing hole 31 and correspondence, the side that the second installing hole 4151 is fixed on described protective cover 40 in described fan 30.In another embodiment, described protective cover 40 can lock on described fixed mount 20 by the mode of buckle, screw locking.At this moment, the described roof 42 of described blade 47 approximate vertical and diapire 43, and roughly in the same plane, the second side 476 of the blade 47 of the most close described diapire 43 is against described catch 4051.
During the work of described combination of fans, fan 30 rotates and air-flow is sucked from ventilation front plate 27, air flow stream passing through fan 30 and blow to the second side 476 of the blade 47 of protective cover 40.Because described opening 418 is roughly the same with air outlet 33 sizes, the size of described fan 30, can take full advantage of the distinguished and admirable of fan 30.Because the second side 476 of the free section 473 of top blade 47 is pressed on first side 475 of fixed part 471 of lower leaflet 47, described blade 47 is blown to such an extent that rotate and forms an air channel 80(see Fig. 5 between per two adjacent blades 47), thereby make air-flow flow out described opening 418, and blade 47 is blocked and prevent inordinate rotation by described banking stop 453.At this moment, the described roof 42 of described blade 47 almost parallels and diapire 43 make described air channel 80 have best air-out effect.When not needing fan 30 heat radiation or described fan 30 to break down, described blade 47 is owing to action of gravitation covers air channel 80, thereby covers opening 418, just can prevent that dust from entering in the fixed mount 20.
And the blade 47 between the blade 47 between the two described stop tab 403 and the two described stators 405 is less, so its weight is lighter, and resistance is less, and less blast just can order about its rotation.Cause when the power voltage insufficient of described fan 30 distinguished and admirable hour, the blade 47 between the blade 47 between the two described stop tab 403 and the two described stators 405 also can rotate, the radiating effect when having improved power voltage insufficient.
The effect of described banking stop 453 also is to block described blade 47 when described combination of fans produces vibrations, prevents its inordinate rotation, and prevents from mutually colliding or blocking between the blade 47.
