Description

The LED radiation fan

Technical field

The utility model refers to a kind of radiation fan that installs LED on fan frame additional especially relevant for a kind of radiation fan.

Background technique

At present, the fan in the general computer often is applied to the purposes of dispelling the heat, and other purposes or extra additional value seldom can be provided.Yet under the situation about promoting day by day of living standard now, people are for article that the daily life periphery touched, utensil etc., also prefer to novelty that they have in vision, distinguished effect such as peculiar.For example, on the housing of computer fan, install light emitting diode (LED) additional, and this computer fan is arranged in pairs or groups in transparent computer housing, to produce comparatively gorgeous visual effect in appearance.

But, as M255640 number " luminous structure of radiation fan " novel patent of TaiWan, China, or M268644 number disclosed technology of document such as " structure-improved of radiation fan " novel patent, all mainly be provided with the LED luminescent component respectively at the place, four corners of fan frame, though can increase the visual effect that light source produces like this, but be subject to fan frame is the specification kenel of rectangle, so that only can launch light to flabellum by fan frame four corners, and therefore its variability is restricted.

Therefore, the above-mentioned radiation fan that is applied to computer, though visually change to some extent, but often be subject to the normalized kenel of fan frame, the too dull and shortage variability of the feasible visual effect that can present, more difficultly take off existing stereotype, therefore can't visually produce the special effect of other tool style all the time.

The model utility content

Main purpose of the present utility model is to provide a kind of LED radiation fan, and the surcharge that it can increase radiation fan makes the radiation fan of GS General Specificationization more gorgeous by the visual effect that LED produced.

Another purpose of the present utility model is to provide a kind of LED radiation fan, and it is disposed at LED outside the electric fan periphery, can be used as the caution effect, and to prevent fan when not installing protecting wire net additional, staff comes to harm because of the flabellum in the false touch rotation.

To achieve the above object, the utility model provides a kind of LED radiation fan, comprise fan frame body, fan stator and flabellum rotor, the air-flow through hole that has perforation on the fan frame body, and in the air-flow through hole, be provided with stator seat, fan stator is located on the stator seat, and flabellum rotor engages with fan stator revolvably; Wherein, this fan frame body is set up wall thickness at this air-flow through hole inner edge place, is concaved with on this wall thickness to be centered around air-flow through hole groove on every side, is provided with the LED luminescent component in the described groove.

Compared to prior art, the utility model is by being configured in the LED luminescent component around the electric fan, make its flicker or conversion light color, not only strengthened the visual effect of fan, can also come to harm for the flabellum that prevents staff false touch rotation and play warning effect, increase the surcharge of fan.

Embodiment

Be further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended accompanying drawing only provides reference and explanation, is not to be used for the utility model is limited.

See also Fig. 1 and Fig. 2, be respectively the utility model first embodiment's perspective exploded view and three-dimensional combination schematic representation.The utility model provides a kind of LED radiation fan, comprises fan frame body 1, fan stator 2 and flabellum rotor 3; Wherein:

This fan frame body 1 can be the normalized kenel of general radiation fan.Have the air-flow through hole 10 that connects its two end surfaces on the fan frame body 1, and in air-flow through hole 10, be provided with stator seat 11 (promptly as shown in Figure 3); This stator seat 11 is in order to provided thereon for above-mentioned fan stator 2, and flabellum rotor 3 then engages with fan stator 2 revolvably.Because above structure is same as the prior art, and be not emphasis of the present utility model, so summary and not giving unnecessary details only.

See also shown in Figure 3, the utility model is mainly under the situation of the normalization size that does not influence fan frame body 1 periphery, make fan frame body 1 set up wall thickness 12 at air-flow through hole 10 inner edge places, be concaved with on this wall thickness 12 and be centered around air-flow through hole 10 groove 120 on every side, be wall thickness 12 all being concaved with the groove 120 that is centered around around the air-flow through hole 10 on arbitrary end surfaces of fan frame body 1 relatively, then be provided with LED luminescent component 4 in the groove 120.In the utility model first embodiment, described groove 120 continuously around this air-flow through hole 10 and in the form of a ring, can be circular ring-type (promptly as shown in Figure 2) or be polygonal ring-type (promptly as shown in Figure 8), and the opening of described groove 120 towards perpendicular to fan frame body 1 surface with air-flow through hole 10 towards consistent (promptly as shown in Figure 3), described LED luminescent component 4 be two or more and arranged spaced in described groove 120 in the form of a ring, and each LED luminescent component 4 is single a kenel.

In addition, as shown in Figure 4, in the utility model second embodiment, 120 kenels with two or more arranged spaced of described groove are centered around around the air-flow through hole 10, and each LED luminescent component 4 also is located at respectively in each groove 120 with the single type attitude.

Fig. 5 and shown in Figure 6 and for example, in the utility model the 3rd embodiment, described groove 120 is identical with above-mentioned first embodiment, but LED luminescent component 4 is for lamp bar kenel and cooperate described groove 120 to bury underground.

Moreover, as shown in Figure 7, in the utility model the 4th embodiment, the opening of described groove 120 towards also tiltable in fan frame body 1 surface and be partial to air-flow through hole 10 places, the part ray cast that it can be launched for LED luminescent component 4 is strengthened the gorgeous effect of light with the spinning movement that cooperates flabellum rotor 3 on flabellum rotor 3.

In view of the above, because being located at, LED luminescent component 4 is centered around in air-flow through hole 10 groove 120 on every side, therefore when radiation fan makes its flabellum rotor 3 runnings after energising, LED luminescent component 4 also can be launched and is centered around the light around the flabellum rotor 3 and produces gorgeous visual effect, simultaneously because light is centered around flabellum rotor 3 peripheries, therefore when radiation fan does not install protecting wire net additional, also the light that can be launched by LED luminescent component 4 is subjected to unexpected injury to prevent staff because of the flabellum rotor 3 in the false touch rotation as caution.

In addition, described LED luminescent component 4 also can make its light of launching present visual effects such as flicker, change light color by the program control mode of circuit board; And adopting under the situation of two or more LED luminescent components 4 as embodiment, also can make each LED luminescent component 4 light of light different colours respectively, can certainly cooperate above-mentioned flicker or change effect such as different light rays color in turn and strengthen sense of vision.

Therefore, by above-mentioned contexture, can obtain the utility model LED radiation fan.

The above only is a preferable possible embodiments of the present utility model, is not so limits to claim of the present utility model, and therefore the equivalent structure done of all utilization the utility model specifications and accompanying drawing content changes, and all in like manner is included in the scope of the present utility model.
