Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a reciprocating translation power component which is convenient to install. Background Art

[0002] Electric hair clippers and personal care products usually use a micro permanent magnet DC motor as the power source. The motor converts the rotary motion into a linear motion through an eccentric wheel structure, so as to drive the cutter head to work. Although this design is simple and reliable, the eccentric wheel structure determines that the working frequency and service life of the motor are limited, and since the rotary motion of the motor is converted into a linear motion, vibrations will be generated, resulting in a poor feel for the user during use.

[0003] In recent years, a swinging motor that uses an iron core coil, a permanent magnet, and a resonance spring in cooperation has emerged on the market. Although this kind of motor solves some problems of traditional motors to a certain extent; for example, the swinging motor may have a problem of insufficient power output in actual applications, which limits its performance under high load conditions; and the design of the swinging motor is relatively complex, and the installation and maintenance processes are rather cumbersome.
