connects to an outer side of the second hub 300.

[0028] A plurality of embodiments in the present disclosure, in order to retain a

sufficient airflow channel, wherein the first hub 100 is a hollow cylinder, and the

centrifugal blades 200 are evenly arranged on an outer circumference of the first hub 100; further, the second hub 300 is also a hollow cylinder, arranged in a middle of the first hub 100 while locating on a same centerline as the first hub 100; the radial blades 400 are evenly arranged on an outer circumference of the second hub

300 and connecting with the inner side of the first hub 100. Wherein, the first hub

100 and the centrifugal blades 200 are forming a centrifugal impeller 10, the

second hub 300 and the radial blades 400 are forming a radial impeller 20, while

the radial impeller 20 locates in a middle of the centrifugal impeller 10, both are

composing into a whole.

[0029] In an actual application, the radial impeller 20 is connected to a driving

device outside (not shown in the FIG.s), before the driving device drives the radial

impeller 20 to rotate, the centrifugal impeller 10 will follow and make a synchronous

rotation, that makes the radial impeller 20 achieve an air supply in a radial direction,

while the centrifugal blades supply air to a surrounding, thereby greatly increasing

an air supply area and realizing a multi-angle air supply. It should be understood

that, the present disclosure does not limit a type of the driving device, which may

be an indirect drive or a direct drive. In an embodiment, making an indirect drive by

using a driving shaft in a middle of the radial impeller 20, or making a direct drive in

a way of a brush motor or a brushless motor, by arranging an assembly including a

stator and a rotor.

[0030] Wherein an axial size of the second hub 300 is greater than that of the

first hub 100, and a number of the centrifugal blades 200 is greater than that of the

radial blades 400.

[0031] As a further solution, referencing to FIG. 1 up to FIG. 5, wherein FIG. 4

illustrates a sectional diagram on an A-A direction in the FIG. 3; FIG. 5 illustrates a

sectional diagram on a B-B direction in the FIG. 3. An inner side of the second hub

300 has a plurality of connection buttons 310 arranged following an axial direction,

the connection buttons 310 are evenly distributed along a circumferential direction

of the inner side of the second hub 300, while the connection buttons 310 are

rectangular-shaped.

[0032] A plurality of embodiments in the present disclosure, wherein the

second hub 300 is applied to connecting with the driving device, before rotating

under a driving force of the driving device; wherein the connection buttons 310 and

the second hub 300 are connected integrally, the connection buttons 310 are

applied to fixedly connecting the second hub 300 to the driving device, and

transferring a driving force to the second hub 300; in an embodiment, when the

second hub 300 needs to connect with a driving shaft, the driving shaft has a

plurality of button slots (not shown in the FIG.s) arranged and adapted with a shape

of the connection buttons 310, by arranging the connection buttons 310 into the

button slots, it is possible to connect the second hub 300 with the driving shaft, thus

when the driving shaft rotates, the driving shaft will drive the second hub 300 to

rotate synchronously through the connection buttons 310. It should be noted that, in

order to ensure the connection buttons 310 have enough strength when

transferring the driving force, the connection buttons 310 are preferred to be in a

rectangular shape. Preferably, a number of the connection buttons 310 is three, of course, there is no limitation to a specific number of the connection buttons 310 in the present disclosure.

[0033] As a further solution, the wind blade structure capable of air guide

further comprises a plurality of connection plates 500, the connection plates 500

are evenly arranged on a circumference of the first hub 100, an outer side of the

connection plate 500 connects with the centrifugal blade 200, and an inner side of

the connection plate 500 connects with one end of the radial blade 400; wherein

the connection plates 500 are in an arc-shape and consistent with an arc of the first

hub 100.

[0034] A plurality of embodiments of the present disclosure, since the axial

size of the second hub 300 is greater than that of the first hub 100, while a number

of the radial blades 400 is less than that of the centrifugal blades 200, thus a size of

the radial blades 400 is larger than that of the centrifugal blades 200, which

ensures a sufficient radial air volume; therefore, it is needed to arrange the

connection plates 500 onto the circumference of the first hub 100, while an inner

side of the connection plate 500 and the inner side of the first hub 100 are on a

same arc surface, a part of one end of the radial blade 400 connects to the inner

side of the first hub 100 and the inner side of the connection plate 500, connecting

the radial blades 400 firmly to the first hub 100 through the connection plates 500;

wherein, the connection plates 500 are arranged on a top surface of the first hub

100, and a top surface of the connection plate 500 and a top surface of the second

hub 300 are on a same plane; further, a number of the connection plates 500 is

consistent to a number of the radial blades 400, and an inner side of each connection plate 500 connects to one end of the radial blade 400 of a single.

Furthermore, in order to ensure there is a sufficient airflow channel, to make the

airflow of the radial impeller 20 be able to be diverted to the centrifugal impeller 10

through a gap between the connection plates 500, a size of each connection plate

500 should not be overlarge. Wherein a number of the connection plates 500 is

three, and an outer side of each connection plate 500 connects with three

centrifugal blades 200. Of course, a number of the connection plates 500 and a

number of the plurality of centrifugal blades 200 connecting with each connection

plate 500, are both for examples only, and should be set according to a

requirement in an actual application.

[0035] As a furtherer solution, an end of the centrifugal blade 200 connecting

to the outer side of the first hub 100 is a straight edge, an end of the centrifugal

blade 200 away from the outer side of the first hub 100 is an arc edge. Wherein the

straight edge vertically connects to the outer side of the first hub 100, the arc edge

and the straight edge are connected integrally. By arranging the end away from the

outer side of the first hub 100 into an arc edge, a contact area of the centrifugal

blades 200 and the airflow is maximized, thereby an air volume supplied is

increased.

[0036] It is noted that, the centrifugal impeller 10 in peripheral needs to push

the airflow in a center around through a rotation of the centrifugal blades 200,

thereby reducing a wind pressure in the center, and thereby reducing a wind

resistance of the radial impeller 20 in a center position when working, further under

an action of a centrifugal force, the blades may reduce an energy consumption by relying on an inertial motion, thus reducing a power consumption of the driving device. Also, such a design of a two-way air supply, makes both a supplied airflow and an air supply angle increase, which is able to increase an air intake amount in a limited space, improving an effect of heat dissipation and ventilation.

[0037] A working principle of the wind blade structure capable of air guide of

the present disclosure is described in details hereafter, combining with FIG. 6.

[0038] By connecting the second hub 300 to the driving device outside and

driving the second hub 300 to rotate through the driving device, the radial impeller

arranged on the second hub 300 rotates, and at a same time, the first hub 100

connected to the radial impeller 20 follows and rotates, thus the centrifugal impeller

arranged on the outside of the first hub 100 follows and makes a synchronous

rotation. At this time, the second hub 300 and the radial blades 400 are supplying a

first airflow 1 in a radial direction, thereby achieving an air supply in the radial

direction, while the first hub 100 and the centrifugal blades 200 are supplying a

second airflow 2 in a circumferential direction, thus achieving supplying the airflow

around.

[0039]AII above, the present disclosure provides a wind blade structure

capable of air guide, comprising: a first hub 100; a plurality of centrifugal blades

200, arranged on an outer side of the first hub 100; a second hub 300, arranged on

an inner side of the first hub 100; a plurality of radial blades 400, one end of the

radial blade 400 connects to the inner side of the first hub 100, another end thereof

connects to an outer side of the second hub 300. The wind blade structure capable

of air guide provided in the present disclosure, through arranging the centrifugal blades 200 onto the first hub 100, and arranging the radial blades 400 onto the second hub 300, as well as connecting both into a whole, is possible to achieve supplying the air horizontally to a surrounding, at a same time of supplying the air in a radial direction, thereby greatly increasing an air supply area and realizing a multi-angle air supply.

[0040] Those skilled in the art will easily think of a plurality of other

embodiments of the present disclosure, after considering the description and

practicing the solutions disclosed herein. The present disclosure is intended to
