Description

Illuminated cooling fan

Technical field:

The utility model relates to the technical field of fans, in particular to a light-emitting cooling fan applied to computers or power supplies.

Background technique:

The cooling fans generally used in computers, power supplies and other equipment are usually composed of a fan base and fan blades. When in use, the fan blades rotate to speed up the air flow and achieve heat dissipation. The original cooling fan is monotonous in shape and lacks aesthetic feeling. Therefore, many manufacturers add LED lights that can emit light to the cooling fan, so as to obtain a cooling fan that can generate rotating bright light. At present, there are many kinds of fans with LED lights on the market. Most of the LED lights are added to the fan frame, and most of them are three or four. When the fan is running, an irregular light arc is formed, and the frame leaves must be made of transparent materials. The cooling fan of this structure is limited in structure, and the effect of emitting light is not ideal.

Invention content:

The purpose of this utility model is to overcome the deficiencies of the prior art and provide a luminous cooling fan constructed on the principle of a generator. This creates a constantly changing light.

In order to achieve the above purpose, the utility model is mainly composed of a fan base and a fan blade. LED lights are combined on the fan blade, and a generator set is provided at the junction of the fan blade and the fan base. The generator set is connected with a PCB board and LED lights to form a light-emitting circuit. The PCB board is equipped with a rectifier circuit and a filter circuit. The generator set is composed of an iron core wound with enameled wire and a magnetized quadrupole magnetic frame. The iron core is fixed in the fan blade, and the magnetic The frame is installed on the shaft seat of the fan seat.

The LED lights can be one or more, and a flashing IC can be bonded on the PCB to control the LED lights, and a flashing IC can also be bonded in the LED lights.

After adopting the above structure, the utility model has the following advantages: 1. The LED light is combined on the fan blade, so that the frame leaf is not limited by the transparent material, and the application area is wider; 2. The iron core wound with enameled wire and a magnetized The generator set composed of a four-pole magnetic frame supplies power to the LED lights, and the generator set is installed in the fan blades to avoid excessive winding and laying of connecting wires, and the appearance is neat and beautiful; 3. The LED lights can be one or more. A flickering IC is bonded on the PCB board to control the change of the LED light to produce a dreamy and gorgeous halo and increase its decoration.

Description of drawings:

Accompanying drawing 1 is the composite structure schematic diagram of the present utility model;

Accompanying drawing 2 is the circuit diagram of one embodiment of the utility model.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in accompanying drawings 1 and 2, the utility model mainly includes a fan seat 1 and a fan blade 2. There is an upwardly protruding shaft seat 11 in the middle of the fan seat 1 for inserting and combining the central axis of the fan blade 2. Relative rotation can be realized, and a coil and a magnet are installed between the fan blade 2 and the fan base 1. Once the coil is energized, the fan blade 2 can be rotated to achieve the effect of heat dissipation. One or more LED lamps 3 are combined on the fan blade 2, and a blinking IC can be properly bonded to the LED lamp 3, so as to control the LED lamp 3 to emit light in a regular manner.

A generator set is arranged at the combination of the fan blade 2 and the fan seat 1. The generator set forms a light-emitting circuit with a PCB board 4 and an LED lamp 3. The generator set consists of an iron core 51 wound with an enameled wire and a magnetized The magnetic frame 52 is composed of four poles, the iron core 51 is fixed in the fan blade 2 , and the magnetic frame 52 is installed on the shaft seat 11 of the fan seat 1 . When the fan blade 2 rotates, the iron core 51 of the enameled wire rotates accordingly, and the enameled wire on it moves to cut the magnetic force lines in the magnetic frame 52, thereby generating alternating current. The AC power is converted into DC power by the rectifier circuit and the filter circuit on the PCB board 4 , and then supplied to the LED lamp 3 .

As shown in FIG. 2 , in this embodiment, the rectifier circuit on the PCB 4 is a bridge rectifier circuit composed of diodes D1 , D2 , D3 , and D4 , and the filter circuit is a capacitive filter circuit composed of capacitor C1 . A flashing IC of the LED lamp can be properly connected to the output end of the filter circuit to control the LED lamp; meanwhile, the flashing IC can be directly bonded to an LED lamp 3 . When the fan blade 2 is running, a regular halo will appear through this full-color flashing LED light 3; you can also directly add an LED light 3 without adding an LED light flashing IC, and a circular halo will appear when the fan is running. The effect is remarkable and the decoration is stronger.

The utility model is to add a generator set between the fan blade 2 and the fan base 1, and use the rotation of the fan blade 2 to generate electricity. The structure is strong, and the production combination is convenient. The fan blade 2 and the fan base 1 are not limited to transparent materials. , which is conducive to product development. The alternating current generated by the generator set is converted into direct current by the rectification circuit and the filter circuit of the PCB board 4, and then supplies power to the LED lamp 3, so as to change the defect that the power source needs to be connected from the host in the past.

Of course, the above-described embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all equivalent changes made according to the shape, structure and principle of the present utility model should be Covered within the protection scope of the present utility model.
