Fan 100 according to embodiments of the present invention is described below with reference to Fig. 1-Fig. 9.
A kind of fan 100 according to embodiments of the present invention, including：Fore shell 1, rear shell 2, centrifugal wind wheel 4 and motor driver
5.As depicted in figs. 1 and 2, there is air outlet 11, air outlet 11 is set adjacent to the outward flange of fore shell 1, and rear shell 2 is located on fore shell 1
The rear side of fore shell 1 and chamber 3 is limited between fore shell 1, there is air inlet 21, centrifugal wind wheel 4 is around fore-and-aft direction on rear shell 2
Axis is rotatably arranged in chamber 3, and air outlet 11 and air inlet 21 are located on the inside of the front and rear sides of centrifugal wind wheel 4.Motor drives
Dynamic device 5 is connected with centrifugal wind wheel 4 and drives centrifugal wind wheel 4 to rotate, wherein when motor driver 5 drives centrifugal wind wheel 4, passing through
The air that air inlet 21 enters centrifuges guiding to air outlet 11 by centrifugal wind wheel 4.Centrifugal wind wheel 4 includes circular discs 41 and is located at circle
The blade part 42 of the periphery of shape disk 41, the blade part 42 includes annular frame 421 and is located in annular frame 421 and axially extends
Multiple blades 422, multiple blades are uniformly distributed circumferentially.It is optional, multiple hollow-out parts 411 are provided with circular discs 41, so as to
Reduce the overall weight of centrifugal wind wheel 4.Preferably, in centrifugal wind wheel 4 in the radial direction, the blade of centrifugal wind wheel 4 be located at into
The outside in air port 21 and the inner side for being located at air outlet 11.In the following description, with reference to Fig. 1-Fig. 9 and with fore shell 1 and rear shell 2
It is all formed as illustrating exemplified by toroidal shell.Certainly, those skilled in the art are appreciated that the fan that the present invention is described
Fore shell and rear shell can also be formed generally as the shapes such as rectangle, ellipse or polygon more than four sides, i.e., in the present invention
In, the shape of the fore shell of fan 100 and rear shell is not specifically limited.
Thus, during work, wind enters in chamber 3 from the air inlet 21 of rear shell 2, is quickly rotated height by centrifugal wind wheel 4
The air of speed is thrown on the perisporium of rear shell 2, and air higher-pressure region is formed between the outward flange of fore shell 1, rear shell 2 and centrifugal wind wheel 4,
Then the air of higher-pressure region sprays at a high speed from the air outlet 11 on fore shell 1, and the high-speed air now sprayed drives fore shell 1 and shell
Air blowing around 2.In a preferred exemplary, the side wall relative with the blade 422 of centrifugal wind wheel 4 of chamber 3 and centrifugation
Enclosed construction is constituted between wind wheel 4, i.e., above-mentioned air higher-pressure region is formed in the enclosed construction.
Fan according to embodiments of the present invention, centrifugal wind wheel 4 is located in chamber 3, and blade is can't see outside fan, it is ensured that
The aesthetic property of outward appearance and dust can be prevented, and solve the application risk that conventional fan is come due to fan high speed rotating band.
In addition, driven at a high speed and blown out from the neighbouring outer peripheral air outlet 11 of fore shell 1 by centrifugal wind wheel 4 into the air in chamber 3, it is empty
Gas velocity is high, and considerably reduces noise.
Preferably, rear shell 2 includes back plate 201 and is connected to the peripheral plate 202 of the periphery of back plate 201, wherein recess 22 by
A part for back plate 201 is recessed forward and is formed, surface blending between peripheral plate 202 and back plate 201.Alternatively, peripheral plate 202
Pass through cambered surface or parabola transition between back plate 201.For example as shown in Fig. 2 passing through between peripheral plate 202 and back plate 201
The transition of cambered surface 203.Thus, by setting surface blending, the air that can throw away centrifugal wind wheel 4 is directed at air outlet 11,
The energy loss in chamber 3 is reduced, so as to further increase air flow efficiency, and noise is reduced.
In some optional examples of the present invention, air outlet 11 is in a ring, and coaxial with centrifugal wind wheel 4（It is not shown）.
That is, air outlet 11 can also be a round wind outlet 11 along the circumferentially extending of fore shell 1, for example can be annulus
Shape, or oval ring.In other optional examples of the present invention, shown as shown in Figure 1, Figure 3 and Figure 4, air outlet 11 is
Multiple and be uniformly arranged along the circumference of fore shell 1, thus air-out is uniform, and fore shell 1 manufactures simplicity.Alternatively, as shown in figure 1, often
Individual air outlet 11 is formed as arcuate shape, and so multiple air outlets 11 can be around a general toroidal be formed, and the annular is located at
The edge of fore shell 1 is to improve air-out efficiency.Or alternatively, each air outlet 11 may be formed as rectangular shape（Figure is not
Show）.Certainly, the present invention is not limited thereto, in still other example of the present invention, and air outlet 11 can also be radially from interior
Outside be distributed it is multiple, it is not shown
In the other example of the present invention, deep bead 13 is also formed with the center of fore shell 1, air outlet 11 is around gear
Aerofoil 13 is set, not shown.
As shown in figs 2-4, there is recess 22 recessed forward, wherein air inlet 21 is located at recess 22 on rear shell 2
Perisporium on, so in the rotation process of centrifugal wind wheel 4, air enters from air inlet 21 fashionable can enter directly into centrifugal wind wheel
With high-speed motion therewith in the 4 high speed rotary areas driven, rear shell 2 is simple for structure in addition, easily manufactured.Alternatively, it is recessed
The center in portion 22 and centrifugal wind wheel 4 are coaxial.Preferably, recess 22 is formed as circular, and the external diameter of recess 22 is less than centrifugation
The external diameter of wind wheel 4, as shown in figs 2-4.By the reason of recess 22 constructed on rear shell 2, chamber 3 is divided into substantially ring
Shape structure, so that when centrifuging conduction to rear shell or fore shell by centrifugal wind wheel 4, i.e., higher-pressure region is formed in chamber 3, and
Due to the physical isolation of recess 22, air in higher-pressure region will not mutually crosstalk so that can be more quickly at air outlet 21
The fan is left, more preferable cooling effect is derived from.
Further, as shown in Figure 3 and Figure 4, air inlet 21 includes multiple, and multiple air inlets 21 are in the week of recess 22
It is uniformly distributed on wall, so that air intake is uniform, further increases air intake efficiency and reduce noise.
In the further embodiment of the present invention, as shown in Fig. 5-Fig. 6 b, each air intake of correspondence on the inwall of rear shell 2
The guide plate 23 of the extension towards in chamber 3 is respectively provided with mouth 21, thus, by setting guide plate 23, on the one hand can prevent from using
Family is stretched into finger when in chamber 3 by the rotating vane injury of centrifugal wind wheel 3 from rear shell 2, on the other hand can guide from air intake
The flow direction for the air that mouth 21 enters in chamber 3.In some optional examples wherein, guide plate 23 is formed as arc.It is preferred that
Ground, the multiple shapes of guide plate 23 and bending direction all same, it is possible thereby to make air along the bending direction of guide plate 23（For example
The direction of arrow as shown in Fig. 5 and Fig. 6 a）Into in chamber 3, so as to further increase the air intake and air-out efficiency of fan.
In other optional examples, guide plate 23 may be formed as swash plate（It is not shown）, wherein swash plate is relative to centrifugal wind wheel
Radial skew, i.e., limit acute angle or obtuse angle between the radial direction of swash plate and centrifugal wind wheel 4（It is not equal to 90 degree and 180
Degree）.Certainly wherein it is preferred that the incline direction of swash plate is consistent.The present invention is not limited to such scheme, such as in the present invention
Still other example in, the multistage plate that guide plate 23 can also be formed by connecting by multistage straight panel and/or arc.
The setting of motor driver 5 and structure will be illustrated below.Motor driver 5 is arranged to drive centrifugal wind wheel
4 around its fore-and-aft direction axis rotate, i.e., motor driver 5 main shaft 501 drive centrifugal wind wheel 4 rotate.Specifically, as schemed
