detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

1 is a schematic structural view of an embodiment of an LED fan according to the present invention. In this embodiment, the LED fan includes a base 10, a motor 20, and a blade 30. Wherein, the blade 30 includes a cylindrical hub 31 and a plurality of blades 32 extending outward from the side of the cylindrical hub 31. The blade 32 is provided with a light-emitting element row 40 which is controlled by a control circuit board 80 to emit light. In addition, the LED fan further includes a USB interface 50 and a power supply device 60. The USB interface 50 is electrically connected to the control circuit board 80 and can be disposed on the base 10 or the blade 30. The power supply device 60 can supply power to the USB interface 50 and the control circuit board 80. In the embodiment shown in FIG. 1, the USB interface 50 is disposed on the end face of the cylindrical hub 31 facing the user, and the power supply unit 60 is located between the motor 20 and the blade 30. In one embodiment, the power supply unit 60 is provided with a magnetic cylinder and a coil that provides power to the USB interface 50 and the control circuit board 80.

The control circuit board 80 can be a PCB (Printed Circuit) The board, the printed circuit board, can be powered by the light-emitting element row 40, which supplies power to the light-emitting element row 40 and the USB interface 50, and is provided with a control circuit for controlling the operating state of the light-emitting element row 40. USB interface 50 can be Mini USB interface or standard USB interface for data interaction with external data processing devices (such as computers, mobile phones, etc.), such as receiving pictures or audio files transmitted by external data processing devices, or transmitting multimedia files saved on control circuit board 80 To an external data processing device.
