Description

technical field [0001] The invention belongs to the technical field of motor equipment, in particular to an electric toothbrush high-frequency vibration motor. Background technique [0002] The high-frequency vibration motor of the electric toothbrush is evolved from the traditional DC motor. By controlling the direction of the current flowing into the winding, the N-pole magnet and the S-pole magnet are deflected to drive the core rotor to reciprocate and drive the spring connected to the shaft. Reciprocating torsion produces torsional deformation. Existing products of the same kind use rod-shaped springs to reciprocate to produce torsional deformation to reset. This method is prone to fatigue and aging during high-frequency reciprocating vibration, and its structural design is also complicated. There are almost 15 parts or more. Coordination of components is prone to resonance, resulting in high noise, and the assembly process is complicated and costly. Contents of the i...
