The present invention proposes a kind of blower 100 referring to FIG. 1 to FIG. 4, the blower 100 include external stator component 1 and
Blade and internal rotor integral structure 2 with fixing axle, wherein the external stator component 1 is arranged in a ring, described to have admittedly
The blade and internal rotor integral structure 2 of dead axle include internal rotor component 21, the multiple blades 22 of vertically axis rotation setting
And installation axle 23, the middle part of the internal rotor component 21 have mounting hole 21a, the internal rotor component 21 is equipped with hollow-out parts
21b, the hollow-out parts 21b is circumferentially arranged, the multiple blade 22 be housed in the hollow-out parts 21b and with the internal rotor
Component 21 is fixedly connected, so that the blade 22 and the internal rotor component 21 be along radial arrangement, the installation axle 23
Lower end is fixing end, and the fixing end to be fixed on the lower cover 3 of the blower 100, stretch by the upper end of the installation axle 23
Enter to the mounting hole 21a, is rotatablely installed for the rotor hub 211, blade and the internal rotor one with fixing axle
Change the inside that structure 2 is set to the external stator component 1, so that the internal rotor component 21 and the external stator component 1 are in interior
Outer ring setting.
In technical solution of the present invention, multiple blades 22 be housed in the hollow-out parts 21b and with the internal rotor component
21 are fixedly connected so that the blade 22 and the internal rotor component 21 be along radial arrangement, one side blade 22 with interior turn
Sub-component 21 is radially disposed, thus blade 22 will not occupy additional axial space, so that the axial ruler of the blower 100
It is very little to accomplish smaller, on the other hand the secured of internal rotor component 21 is achieved that in such a way that the lower end of installation axle 23 is fixed
Installation, and the lower end of the installation axle 23 is fixedly mounted on the lower cover 3, rather than be rotatably installed in using installation axle 23
Lower cover 3, and then installed not necessarily in bearing 24 is arranged at the lower cover 3 for the installation axle 23, and then lower cover 3 can be with
It is arranged more simple, and lower end is fixed, upper end suspension, without fixed structure being arranged in upper end cover or even unnecessary setting
Set upper end cover.
In an embodiment of the present invention, mounting structure of the installation axle 23 as the internal rotor component 21, using lower end list
Point is fixed, and the installation axle 23 is poorer further away from lower end supporting point intensity, easier circular runout, thus in order to enhance the peace
The strength and stability for filling axis 23, avoids installation axle 23 in 21 rotation process of internal rotor component, deforms radially
And lead to the interior runner assembly circular runout and then influence stability, the installation axle 23 is from top to bottom set as aggravating to set
It sets, it is of course also possible to be to be set as aggravating from top to bottom by the internal rotor component 21 and 22 at least one of them of the blade
Setting, and make the center of gravity of the rotating member of the internal rotor component 21 and the composition of the blade 22 closer to lower supporting point, and make
The rotational stability for obtaining rotating member is good.
The internal rotor component 21 rotational installation in the installation axle 23 concrete form with no restrictions, in order to further subtract
The axial dimension of the small blade and internal rotor integral structure 2 with fixing axle, in an embodiment of the present invention, the peace
It fills and is formed with annular gap between the inner sidewall and the installation axle 23 of hole 21a, 23 turning set of installation axle, which is equipped with, is located at institute
State multiple rolling bearings 24 in annular gap, the internal rotor component 21 by the multiple rolling bearing 24 be rotatablely installed in
The installation axle 23, the multiple rolling bearing 24, which is arranged in the annular gap, prevents take up additional axial dimension, difference
In bearing 24 is arranged using the upper end cover 4 and lower cover 3 in blower 100, so as to avoid on the one hand making upper and lower end cap 3
Structure is complex, and on the other hand can make bearing 24 and internal rotor component 21 is axial distribution, can occupy biggish axial ruler
It is very little.
The fixed form of 23 fixing end of installation axle and the lower cover 3 with no restrictions, in an embodiment of the present invention,
The lower cover 3 is equipped with fixation hole, and the fixation hole is equipped with mounting blocks, and the fixing end of the installation axle 23 and the mounting blocks are solid
It is fixed.In other embodiments of the invention, the fixing end of the installation axle 23 and the lower cover 3 are integrally formed, and are made thus
The stability of the installation axle 23 is more preferable.
Specifically, in an embodiment of the present invention, the internal rotor component 21 includes rotor hub 211 and permanent magnet
212 and rotor core 213, the mounting hole 21a are set to the middle part of the rotor hub 211, and the hollow-out parts 21b is set to described
On rotor hub 211, the hollow-out parts 21b is circumferentially arranged, and the rotor hub 211 is divided for inner ring and outer ring, described
Permanent magnet 212 and rotor core 213 are set to the outer end of the outer ring, and the inner end of each blade 22 is fixed with the inner ring,
Outer end is fixed with the outer ring, so that the blade 22 and the rotor hub 211 are along radial arrangement.
The multiple blade 22 and the rotor hub 211 are connected as one by the design, for this purpose, in the rotor hub
In 211 rotation processes, the rotor hub 211 can be born compared with noticeable effort, which includes axial force and radial force, especially
It is the effect of radial force so that the rotational stability of the rotor hub 211 is subjected to biggish test, for this purpose, in reality of the invention
Apply in example, the multiple blade 22 and the rotor hub 211 be integrally formed, avoid thus because the multiple blade 22 with
The rotor hub 211 further causes undesirable influence to the stability of the rotor hub 211 using split settings, when
Right the design is without being limited thereto, it is clear that the rotor hub 211 and the multiple blade 22 can also use split settings and group connects
It is integrated, then the structure assembled at this time wants firm and mitigates the influence to the stability of the rotor hub 211 as far as possible.
