TECHNICAL FIELD

[0001] The application relates to the technical field of magnetizing technology, in particular to a rapid magnetizing device for a fan magnetic ring. BACKGROUND

[0002] A heat dissipation fan needs to be magnetized by a magnetizing device, and the magnetizing device is no longer applicable to a new product after the heat dissipation fan is changed at any time in the design stage, and the subsequent idleness of the magnetizing device is large, thereby causing waste.

[0003] To this end, a rapid magnetizing device of a sinusoidal magnetizing waveform is disclosed in Chinese Patent Application No. CN202321106264.6, which mainly adopts an integrated magnetizing main body and a magnetic guide piece with a winding coil to generate a magnetizing waveform in a magnetic ring, thereby realizing a magnetizing effect.
