Description

Technical Field

[0001] This utility model relates to the field of computer fans, and in particular to a computer fan with a central light guide. Background Technology

[0002] Computer fans, also known as cooling fans, are generally used for heat dissipation. They are used in heat sinks and computer cases. In current designs, the faster the blades rotate, the greater the air pressure generated. However, computer fan blades are generally made of plastic, so when the air speed exceeds a predetermined value, the rotation speed cannot increase due to material limitations, thus affecting the amount of air pressure.

[0003] With the development of transparent chassis, the aesthetics of computer fans are also becoming increasingly important. The current practice is to set a light guide structure or display screen at the impeller shaft. However, the existing light guide structure generally uses a two-color injection molding process to achieve the desired optical effect. In actual production, the mold for two-color injection molding is expensive, which affects the market share of the product. Utility Model Content

[0004] The main purpose of this invention is to propose a computer fan with a central light guide, which aims to improve existing computer fans, thereby achieving the desired optical effect, while reducing the production cost of the blades as a light guide structure and increasing market share.

[0005] To achieve the above objectives, this utility model proposes a computer fan with a central light guide, comprising:

[0006] The bearing seat has multiple spaced blades extending circumferentially from its outer wall, and its upper wall has at least two annular grooves.

[0007] The annular groove is provided with through holes spaced apart along the axis;

[0008] A positioning structure, comprising an annular portion that mates with an annular groove, wherein the positioning structure is detachably mounted to the annular groove.

[0009] The annular part is provided with a locking part that extends into the through hole.

[0010] In practical design, by using a split-molded impeller and positioning structure, which are manufactured separately and then assembled, mold costs can be effectively reduced.

[0011] In the first embodiment, the positioning structure is a light guide structure, so an LED light can be set inside the bearing seat, thereby enabling the ring-shaped part to emit light. When rotated, two ring-shaped light-emitting halos can be presented, thereby improving the visual effect.

[0012] In the second embodiment, the positioning structure is a conductive structure. By setting a display on the upper wall of the bearing seat and setting a PCB board on the upper wall of the stator, the multiple electrodes of the display are connected through the through hole, thereby achieving different display effects or light display effects.
