Description

Shaving foil, shaving head and razor

Technical Field

The utility model relates to a body hair shaving device, in particular to a shaving net, a shaving head and a razor.

Background Art

The razor head is a key component used by people for shaving in daily life. There are three types of razor heads at present: one is a reciprocating electric razor that uses a mesh structure to feed hair. This structure cannot allow long hair to enter the cutting hole, that is, the mesh structure of the razor heads we use most of the time cannot cut relatively soft long hair. The second is a reciprocating electric shear head structure used to cut long hair. The electric shear head structure uses a toothed moving blade and a toothed fixed blade to complete the cutting of long hair. In this cutting method, the blade head directly contacts the skin and is easy to scratch. In addition, short hair cannot be cut due to the thickness of the blade. The third is a mesh-type blade head with an electric shear head superimposed on the side, so that the razor has the functions of both short and long hair. This razor head is inconvenient to switch back and forth, and the structure is complex, bulky, and inefficient. How to provide a razor head with a simple structure that can adapt to both short and long hair is the object of research for those skilled in the art.
