When a component is considered to be “connected” to another component, it can be directly connected to another component or other components can exist in between at the same time. Conversely, when a component is described as “directly on” another component, there is no intermediate component. As used herein, the terms “vertical”, “horizontal”, “left”, “right”, “one side”, “another side”, “one end”, “another end” and similar expressions are for illustrative purposes only and are not limitations on the specific orientation of components in the product or device.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those normally understood by those skilled in the technical art of the present disclosure. The terms used in the specification of the present disclosure herein are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. As used herein, the terms “and/or” include any and all combinations of one or more related items listed.

As shown inFIG.1toFIG.3, a fan with multiple light rings according to the present disclosure comprises a lower fan frame cover1, a light guide frame2, an upper fan frame cover3, fan blades4, a shading cover5and an outer light source ring6. The lower fan frame cover1comprises a first vertical portion11, a first horizontal portion12and a central mounting seat13located inside the first vertical portion11. The fan blades4are disposed on the central mounting seat13. The light guide frame2comprises an upper horizontal portion21and a second vertical portion22disposed on an outer side of the upper horizontal portion21. An inner light guide portion23is disposed on an inner side of the upper horizontal portion21. An upper light guide portion24is disposed on an upper side of the upper horizontal portion21. An outer light guide portion25is disposed at a lower end of the second vertical portion22. The second vertical portion22is disposed outside the first vertical portion11. The inner light guide portion23abuts on an upper end of the first vertical portion11. The shading cover5abuts with a portion between the inner light guide portion23and the upper light guide portion24, and the outer light guide portion25abuts on an upper surface of the first horizontal portion12.

The upper fan frame cover3comprises a second horizontal portion31and a third vertical portion32. The second horizontal portion31abuts with a portion between the upper light guide portion24and the upper horizontal portion21. The third vertical portion32is disposed outside the second vertical portion22, and a lower end of the third vertical portion32abuts on an upper surface of the outer light guide portion25. The outer light source ring6is disposed between the lower fan frame cover1and the light guide frame2, and the lower fan frame cover1, the light guide frame2and the upper fan frame cover3fit together to form three light rings.

Specifically, as shown inFIGS.1-2, the outer contour of the projection of the lower fan frame cover1, the light guide frame2, and the upper fan frame cover3in the horizontal direction is square, therefore the structure of the three components will appear different at different positions. Of course, they can also be round, which is not limited. In addition, the lower fan frame cover1and the upper cover3are made of plastic, and both are integrally molded, respectively. Light guide frame2is made of translucent plastic with light guide powder, specifically, it can be PC material. The components of light guide frame2can also be prepared by integral molding. For the square lower fan frame cover1, the light guide frame2, and upper fan frame cover3, these three components can be assembled together using screws by means of screw mounting posts disposed at the four corners of the lower fan frame cover1and upper fan frame cover3, and the through hole disposed in the light guide frame2, but not limited to this.

Since the outer contour of the projection of the light guide frame2in the horizontal direction in the present embodiment is square, therefore, the structure of the light guide frame2at different positions has certain differences. Specifically, as shown inFIG.3, the inner light guide portion23is set horizontally. Of course, the inner light guide portion23at the four corners of the square may also be set obliquely, and there is no limit to this.

The side of the inner light guide portion23towards the inside the lower fan frame cover1forms an inward inner light ring231, the upper light guide portion24forms an upward upper light ring241, and the side of the outer light guide portion25towards the outside of the lower fan frame cover1forms an outward outer light ring251. Thereby, by means of the setting of the specific structure of the lower fan frame cover1, the light guide frame2and the upper fan frame cover3, with the shading cover5and the outer light source ring6, use a light guide frame2to guide the light emitted by the outer light source ring6, which can form three light rings on the inner side, outer side and upper side of the fan frame, so as to obtain the luminous effect of multiple light rings, so that the luminous effect of the fan is more attractive, and the structure is simple.

Further, a motor7and a central light source ring8are disposed on the upper surface of the central mounting seat13. An output shaft of the motor7is connected with a light guide cover9, and the light guide cover9covers the motor7and the central light source ring8. At least part of the upper surface of the light guide cover9is covered by a nameplate10, and the fan blades4are disposed around the light guide cover9.

It is understandable that the output shaft of the motor7can drive the light guide cover9to rotate, and then drive the fan blades4to rotate. Specifically, the motor7is disposed on the upper side of the central light source ring8, and the motor7does not block the light-emitting portion of the central light source ring8, thereby allowing the light emitted by the central light source ring8to illuminate the light guide cover9. On the one hand, the light guide cover9is used to protect the motor7and the central light source ring8, on the other hand, it can be used to guide the light emitted by the central light source ring8. Further, the nameplate10is preferably round, but not limited to this. Due to the arrangement of the nameplate10on the upper surface of the light guide9, a central light ring91can be formed at the center of the fan. Therefore, four light rings can be formed on the fan.

Further, the central light source ring8comprises an annular substrate81and a plurality of first light sources82disposed on the annular substrate81at equal intervals.

Specifically, the first light source82herein may be an LED, but not limited to this. In order to obtain a better light guide effect, the annular substrate81is set horizontally, and multiple LED are evenly set along the circumference of the annular substrate81, so that the illumination of the central light ring91is more uniform.

Further, the outer light source ring6comprises an annular strip61and a plurality of second light sources62disposed on the annular strip61at equal intervals.

Specifically, the second light source62herein may be an LED, but not limited to this. The annular strip61is set vertically, and multiple LED are evenly set along the circumference of the annular strip61, so that the illumination of three light rings on the inner side, outer side and upper side can be realized by using only one outer light source ring6, and the illumination is more uniform.

Further, a support portion111for supporting the outer light source ring6is disposed on an outer side of the first vertical portion11.

During use, due to the rotation of the fan or external vibration, the position of the outer light source ring6is easy to shift, thereby affecting the luminous effect of the fan. Hence it is necessary to support and position the outer light source ring6. Therefore, the first vertical portion11is provided with a support portion111on the outer side for supporting the outer light source ring6, in order to resist the lower end of the annular strip61of the outer light source ring6.

Further, the shading cover5is fixed to the inner light guide portion23by means of snap fit.

The snap fit connection can be removed. In the present embodiment, a snap is disposed on the lower surface of the shading cover5(not shown), and a slot is disposed in the inner light guide portion23(not shown). The shading cover5is fixed to the inner light guide portion23by snap fit, so that it is convenient to dispose the shading cover5on the inner light guide portion23or remove it from the inner light guide portion23.

A fan with multiple light rings according to the present disclosure, by means of the setting of the specific structure of the lower fan frame cover1, the light guide frame2and the upper fan frame cover3, with the shading cover5and the outer light source ring6, use a light guide frame2to guide the light emitted by the outer light source ring6, which can form three light rings on the inner side, outer side and upper side of the fan frame, so as to obtain the luminous effect of multiple light rings, so that the luminous effect of the fan is more attractive, and the structure is simple and the assembly is convenient.
