Abstract
A self-luminous cooling fan comprises a casing, an impeller rotationally in pivoted arrangement on the casing, a rotating unit driving the impeller to rotate, and a light-emitting unit arranged on the impeller. A second stator of the light-emitting unit generates electric current by aid of the rotation of the impeller to enable the light-emitting element arranged on the light-emitting unit to emit light, thereby achieving the purpose of auto-luminescence. A hub, a second circuit board and the second stator are simultaneously in penetration state by utilizing a locating section of a central shaft of the impeller, thereby effectively preventing the second circuit board and the second stator being separated from the hub of the impeller, and ensuring the centrality of the second circuit board and the second stator to be located on the same axis with that of the impeller. Therefore, the self-luminous cooling fan can effectively prevent the impeller generating noise due to deflection, and relatively prolongs the service life.
Description
[technical field]
The utility model relates to a kind of radiation fan, particularly relate to a kind of can self luminous radiation fan.
[background technique]
As shown in Figure 1, 2, existing radiation fan 1 comprises a framework 11, and is located at stator 12, on this framework 11 and is hubbed at rotor 13, a conductive unit 14 on this framework 11 and an illuminating part 15 of being located on this rotor 13.
This radiation fan 1 is after the energising running, this first circuit board 112 just can make these stator 12 energization excitations and drive this magnet ring 135 and rotate because of the magnetic mutual exclusion, and drive this rotor 13 and rotate, on the other hand, the electric current of this first circuit board 112 can be passed to this first and second conducting block 143,144 via two brushes 145.This first conducting block 143 sees through this metal material rotating shaft 131, second circuit board 132, first lead, 133 delivered currents again to this illuminating part 15,144 of this second conducting blocks see through these second lead, 134 delivered currents to this illuminating part 15, and are luminous so that the both positive and negative polarity of this illuminating part 15 constitutes a current loop.
Yet existing radiation fan 1 by this conductive unit 14 cooperate this first, two leads 133,134 make this illuminating part 15 luminous, and this first, two leads 133,134 need an end to be electrically connected the illuminating part 15 that is arranged on this rotor 13, the other end then need be extended through this rotor 13 and this hollow shape rotating shaft 131 respectively, be electrically connected this second circuit board 132 and this second conducting block 144 respectively, therefore when design, must additionally on this rotor 13, offer for this first, two leads 133,134 passages that place, its distribution is comparatively difficult, and still must additionally increase for example tenon seat 141, insulation base 142, first, two conducting blocks 143,144, and brush 145, make this radiation fan 1 make the comparatively loaded down with trivial details inconvenience that seems in moulding and the assembling.
For improving the shortcoming of existing radiation fan 1 assembling inconvenience, relevant dealer proposes as the disclosed technology of Fig. 3, be that a fan luminous device 16 is arranged on the existing fan 19, should comprise a framework 191 by existing fan 19, one is arranged at the stator 192 in this framework 191, and one be hubbed in this framework 191 and have the rotor 193 of a rotating shaft 194, and this fan luminous device 16 comprises that one is arranged at the framework 17 on this framework 191, reach a sticking luminescence unit 18 of being located on this rotor 193, this framework 17 has a circle frame 171, one is fixedly arranged on the positioning shaft 172 in this circle frame 171, an and magnet ring 173 that is arranged in this circle frame 171, and this luminescence unit 18 has an integrated plate 181, one is installed on this integrated plate 181 and has several light emitting diodes (Light Emitting Diode, LED) 183 printed circuit board (PCB) (Printed Circuit Board, PCB) 182, one is arranged on this integrated plate 181 and the generating line group 184 that is electrically connected with this printed circuit board (PCB) 182, reaches one in order to the sticking double coated film 185 of establishing this integrated plate 181 and this rotor 193.Rotate to drive these integrated plate 181 these generating line groups 184 of rotation interlock by this rotor 193 with respect to these magnet ring 173 rotations, make this generating line group 184 because of and the mutual variation of 173 magnetic of this magnet ring produce induction electromotive force and generate electric current, make the described light emitting diode 183 on this printed circuit board (PCB) 182 luminous.
But, this double coated film 185 rotates at the rotor 193 that is subjected to this existing fan 19 for a long time, under the heat effects that is produced when luminous with the described light emitting diode 183 on this printed circuit board (PCB) 182, make the stickability of this double coated film 185 to fail rapidly, in the course of time, can cause when this existing fan 19 turns round, this integrated plate 181 because stickability is relatively poor easily by breaking away from this rotor 193, gently then make a noise, heavy this rotor 193 or this framework 17 that then cause damages, the stability when having a strong impact on these existing fan 19 runnings.
Moreover, because this luminescence unit 18 is to mutually combine with this double coated film 185 with this rotor 193, and the positioning shaft 172 of this framework 17, and the rotating shaft 194 of this existing fan 19 is to be fixedly arranged on respectively on this framework 17 and this rotor 193, when therefore utilizing double coated film 185 to be bonded on this rotor 193 as if these luminescence unit 18 desires, then its both centrad certainly will be easy to generate deviation, when the generating line group 184 that causes this rotor 193 to drive luminescence unit 18 is rotated, when skew being arranged if both centrads are inconsistent, will make this rotor 193 when rotating, produce noise, more can significantly shorten the working life of this rotor 193 and this luminescence unit 18, so this kind improvement mode is not a good plan.
