[0028] See also Figure 1 and Figure 2 A cooling fan with data display function includes a frame 100, a driving unit 200 and a fan blade 300. The driving unit 200 is installed on the frame 100, and the fan blade 300 is connected to the driving unit 200. The driving unit 200 drives the fan blade 300 to rotate. The driving unit 200 includes a PCB board 210, a stator part 220, a rotor part 230 and a digital tube 240. The PCB board 210, the stator part 220 and the digital tube 230 are arranged in sequence from the inside to the outside, and the stator part 220 is electrically connected to the PCB board 210. The rotor part 230 cooperates with the stator part 220 to rotate, and the pin 241 of the digital tube 240 passes through the interval of the stator part 220 and is electrically connected to the PCB board 210.

[0029] Specifically, in the present embodiment, the driving unit 200 is mounted on the frame 100, and the fan blades 300 are connected to the driving unit 200. The fan blades 300 can be driven to rotate by the driving unit 200, so as to realize the heat dissipation function. When the driving unit 200 is installed, the PCB board 210, the stator part 220 and the digital tube 240 in the driving unit 200 are arranged from the inside to the outside in sequence, and the stator part 220 is electrically connected to the PCB board 210, and the rotor part 230 cooperates with the stator part 220 to rotate and drive the fan blades 300 to rotate. The PCB board 210, the stator part 220 and the rotor part 230 in the driving unit 200 are prior art, so no further description is given here. At the same time, the digital tube The pin 241 of 240 can directly pass through the gap of the stator part 220 and be electrically connected to the PCB board 210. The pin 241 can support the digital tube 240, so that the overall structure of the drive unit 200 is simple and the layout is reasonable. In addition, the pin 241 of the digital tube 240 can be electrically connected to the PCB board 210 to realize signal transmission and power supply to the digital tube 240. The transmitted data can be displayed through the digital tube 240, such as rotation direction, rotation speed, speed range and other data, so that users can intuitively view their data, thereby improving the overall practical performance of the cooling fan. The data light displayed by the digital tube 240 can also improve the overall visual effect of the cooling fan.

[0030] Of course, in another embodiment, a control circuit board (not shown in the figure) is separately provided for the digital tube 240 to realize a dual circuit board combination, and during assembly, the pins of the control circuit board are also passed through the gaps in the stator part 220 to electrically connect it to the PCB board 210.

When hardware control is adopted, the controller 500 can be set on one side of the frame 100, or close to the driving unit 200, and the controller 500 is electrically connected to the driving unit 200. The driving unit 200 can be controlled by the controller 500, so as to realize the clockwise or counterclockwise rotation of the fan blades 300, and the rotation speed of the fan blades 300 can also be controlled. Similarly, the software control method can also achieve the control effect of the driving unit 200. Of course, the setting of the controller 500 is not necessary, and can be selected according to actual production needs. Moreover, whether the controller 500 is set or not will not affect the data display function of the digital tube 240.

The light-transmitting member 400 can protect the digital tube 240, and the light-transmitting member 400 with a transmittance within this range can clearly view the data displayed on the digital tube 240 from the outside, thereby making the cooling fan more convenient to use. The light-transmitting member 400 can also transmit the light displayed by the digital tube 240, so that the cooling fan has a light-sensing effect when in use, thereby improving the visual perception of the cooling fan.

[0033] See also Figure 1 In this embodiment, in order to realize the connection between the fan blade 300 and the drive unit 200, the fan blade 300 includes a sleeve portion 310 and a plurality of blades 320. When connected, the sleeve portion 310 is directly sleeved on the light-transmitting member 400, so that the sleeve portion 310 and the light-transmitting member 400 have an interference fit, and the plurality of blades 320 are evenly distributed on the outer wall of the sleeve portion 310. Through the interference connection between the sleeve portion 310 and the light-transmitting member 400, the fan blade 300 can be conveniently disassembled and assembled as a whole, and fan blades 300 of different specifications can be conveniently replaced, such as fan blades 300 of different colors, different materials, and different leaf shapes, so as to meet the user's usage needs.
