Description

technical field

[0001] The invention relates to a cooling fan, in particular to a cooling fan with a uniform luminous effect. Background technique

[0002] Most of the existing cooling fans focus on the cooling function, and there is not much change in appearance or other auxiliary functions. Therefore, in order to enhance the visual experience of the cooling fan and break through the stereotype of the existing cooling fan, there is a cooling fan with luminous function. The fan was invented.

[0003] Such as figure 1 , 2 As shown, the existing cooling fan includes a frame 11 , a circuit board 12 arranged in the frame 11 , and a fan wheel 13 rotatably arranged on the circuit board 12 . The inner wall of the frame 11 is provided with a plurality of installation holes 111 (only one installation hole 111 is shown in the figure), and each installation hole 111 is provided with a light emitting diode 112 . The outer peripheral surface of the fan wheel 13 is provided with a plu...
