Description

Technical Field

[0001] The invention relates to the field of shavers, and in particular to a reciprocating shaver transmission structure. Background Art

[0002] A reciprocating electric shaver is a type of electric shaver. It is mainly composed of a cutter head, a motor, a battery, a casing and other parts. The cutter head is mainly composed of a protective net and a cutter net. By starting the motor, the cutter net can be driven to swing back and forth, thus completing the shaving operation.

[0003] In order to expand the working range of the shaver, the existing electric shaver usually sets multiple sets of cutter head assemblies in one device. At the same time, in order to reduce the volume of the overall device, only a single set of motors is often set inside the device. In this case, a transmission device is required to synchronously transmit the movement of the output shaft of the single motor to the two sets of cutter head assemblies. The existing transmission device is mainly composed of multiple sets of swing rods. The rotational movement of the motor output shaft drives the swing frame to swing left and right around the rotating shaft, thereby driving the cutter head assembly to swing left and right. This not only takes up a large space, but also has fewer contact points between the swing rod and the cutter head, and the transmission stability of the overall device is poor. Therefore, a reciprocating shaver transmission structure is proposed to solve the above problems. Summary of the invention
