Description

Fan structure

【Technical field】

A kind of fan structure, espespecially a kind of fan structure with projection light emitting structure.

【Background technology】

Mainly as the active heat sink of forced heat radiation, fan is generally positioned to be provided fan with direct in place of pyrotoxin Direct forced heat radiation uses, or is provided as guiding the space of circulating current to use, and existing with the market demand, fan is except carrying For forced heat radiation and provide outside airflow circulating use, more have dealer in installing light-emitting device on the flabellum of fan, work as fan running When light-emitting device can then produce font or send light, or install LED light bar additional outside the fan hub and produce and light it Effect, but install light-emitting device this equilibrium problem when can cause fan running on flabellum or wheel hub additional again；And because in fan hub Centre is provided with axle center, then fan hub is provided with place of axle center then therefore light-emitting device can not be set can not to produce luminous effect Fruit.

【The content of the invention】

Therefore, it is the shortcoming of the above-mentioned known technology of solution, the main purpose of the present invention, there is provided one kind improves on known fan wheel hub The fan structure of ray structure can not be set by setting at axle center.

To provide a kind of fan structure up to above-mentioned purpose, the present invention, comprising：It is one fan blade hub, a fan base, one hollow Axostylus axostyle；

The fan blade hub has one week portion and a top, and this week portion has plural flabellum；

The fan base has a beam barrel, and the beam barrel content is provided with a luminescence unit and a light-guide device；

There is the hollow axis pole first end and one second end and pass through aperture, the through hole to axially penetrate through the hollow axis pole simultaneously First and second end is connected, the hollow axis pole first end is plugged in the top of the fan blade hub, and described second is connected to foregoing wind Fan in the beam barrel of seat and set with the light-guide device group.

Central shaft is substituted with a hollow axis pole through the present invention, and projection light emitting is carried out in hollow axis pole, thereby Improve known with the missing that can not be lighted at illumination effect Fan axial center.

【Embodiment】

The above-mentioned purpose and its structure of the present invention and characteristic functionally, will be said according to the preferred embodiment of institute's accompanying drawings It is bright.

Fig. 1, Fig. 2 are referred to, is the stereo decomposing and assembled sectional view of the first embodiment of fan structure of the present invention, such as schemes It is shown, fan structure 1 of the present invention, comprising：One fan blade hub 11, a fan base 12, a hollow axis pole 13；

The fan blade hub 11 has one week portion 111 and one top 112, and portion 111 has plural flabellum 113, this week portion 111 within this week Located at the axially outer edge of fan blade hub 11, the top 112 located at 112 radially outer edges of the top of fan blade hub 11, this week portion 111 with The top 112 connects, and the annular array of flabellum 113 is arranged at all portions 111 of the fan blade hub 11.

The fan base 12 has a beam barrel 121, and the content of beam barrel 121 is provided with a luminescence unit 14 and a light-guide device 15, the beam barrel 121 is located in the centre of fan base 12, and the luminescence unit 14 is arranged at the bottom of beam barrel 121, the leaded light The luminescence unit 14 is docked on element 15.

The hollow axis pole 13 has a first end 131 and one second end 132 and pass through aperture 133, the axle of through hole 133 To through the hollow axis pole 13 and first and second end 131,132 is connected, the first end 131 of hollow axis pole 13 is plugged in the flabellum The top 112 of wheel hub 11,112 centres of the top of the fan blade hub 11 have an open-work 114, and the first of the hollow axis pole 13 End 131 is corresponding to be plugged in the open-work 114, second end 132 be plugged in the beam barrel 121 of foregoing fan base 12 and with the leaded light 15 groups of element is set.

When the luminescence unit 14 produces light source 2, light source 2 passes through the light-guide device 15 to the top of fan blade hub 11 112 Projection, the light-guide device 15 be a lens, the produced light source 2 of luminescence unit 14 can be assembled through the lens and directly to The through hole 133 of hollow axis pole 13 directly concentrates projection, makes light source 2 directly to assemble the top for being projected to the fan blade hub 11 The open-work 114 of 112 centre, and the situation for not producing scattering is projected by the through hole 133 of the hollow axis pole 13.

Fig. 3,4 are referred to, are the stereo decomposing and assembled sectional view of the second embodiment of fan structure of the present invention, as schemed institute Show, the present embodiment part-structure is identical with aforementioned first embodiment, therefore will not be described in great detail herein, only the present embodiment and foregoing first Embodiment difference is that the light-guide device 15 is a light-strip（Post）, and the one end of light-guide device 15 is plugged in the hollow axis pole 13 through hole 133, and extend at the first end 131 of the hollow axis pole 13.

Light source 2 then directly is projected to be located at by the light source 2 produced by the luminescence unit 14 through the light-guide device 15 to be somebody's turn to do The top of fan blade hub 11 112, and because of the generally transparent material of fan blade hub 11, therefore light source 2 is directly conducted by light-guide device 15 and thrown Penetrate in the top of the fan blade hub 111 112 and the flabellum 113, improve at the top of known fan blade hub and flabellum generation balances or it His missing.

The flabellum 113 of transparent material can be selected in the flabellum 113 of foregoing first and second embodiment, can more increase light source 2 and be shone The effect penetrated.

The outer rim of beam barrel 121 of the fan base 12 is provided with a circuit substrate 16, and certain son is socketed with outside the beam barrel 121 17, the circuit substrate 16 is electrically connected with the luminescence unit 14 and the stator 17, and the circuit substrate 16 is as control fan And luminescence unit 14 uses, and a bearing 18 is provided between the beam barrel 121 and the hollow axis pole 13.

Through the present invention can improve the known fan with illumination effect can not at the axle center of wheel hub projection source is lacks Lose, and can pass through simple mechanism unit and reach illumination effect.
