Description

Technical Field

[0001] The utility model belongs to the technical field of shavers, and particularly relates to a single-ring shaving head assembly of a rotary electric shaver and a rotary shaver. Background Art

[0002] The structure of a shaver generally includes a body, a head and a cutter head assembly. The cutter head assembly includes a cutter net, a moving blade, etc. The moving blade cooperates with the cutter net during rotation to cut the shaver. The cutter net generally adopts a double-ring cutter net with an isolation ring in the middle, resulting in a relatively small effective shaving area. The cutter net surface does not contact the skin comprehensively. Moreover, the beard inlet groove is a straight groove structure. When shaving while moving, the skin is easily caught in the beard inlet groove, thus hurting the skin. The shaving effect is not good and there is a sense of discomfort. Summary of the Invention
