Example 1

As shown in fig. 1, 2 and 3, the eccentric wheel of the shaver has irregular shape and uneven mass, and comprises a first eccentric part 11 and a second eccentric part 12 which are integrally formed, wherein the mass of the first eccentric part 11 is smaller than that of the second eccentric part 12, the mass is uneven, and the mass ratio is 1:8; the eccentric body 1 is provided with an input slot 3 of a motor in the shaver and an output shaft 2 connected with a driving piece for driving a shaver head of the shaver to move, the input slot 3 is located in the first eccentric part 11, the output shaft 2 is located at the joint of the first eccentric part 11 and the second eccentric part 12, the axis of the input slot 3 and the axis of the output shaft 2 are on the same plane, and the output shaft 2 is located in the middle of the joint.

The eccentric wheel is similar to an original eccentric wheel, a part is cut off along the longitudinal direction, the mass of the first eccentric part 11 is unequal to that of the second eccentric part 12, the gravity center of the eccentric wheel is enabled to transfer to the second eccentric part 12, the positions of the output shaft 2 and the input shaft are moved, the input center of the eccentric wheel is adjusted, the gravity center of the eccentric wheel is enabled to transfer to the second eccentric part 12, and therefore when a shaver head moves, the eccentric wheel can generate vibration opposite to the movement direction of the shaver head, the vibration of the shaver is reduced by offsetting, the use hand feeling of the shaver is optimized, the noise is reduced, and the use experience is improved.

In the present embodiment, the mass ratio of the first eccentric part 11 to the second eccentric part 12 is 1.

Further, the first eccentric portion 11 is in a triangular structure, and since the eccentric wheel has a small volume, the output shaft 2 can be disposed on the first eccentric portion 11, and the portion which is not connected to the output shaft 2 is designed to be removed, so that the first eccentric portion 11 has a required mass.
