Description

Technical Field

[0001] The invention relates to the technical field of razor structures, and in particular to a razor head with a blade positioning structure. Background Art

[0002] With the popularity of electric shavers, the blade cutting efficiency and equipment service life of electric shavers have always been the focus of research and development and optimization of manufacturers.

[0003] After using the long-life blades, in order to ensure the close fitting ability of the structure, reduce the assembly tolerance, and ensure stable operation after assembly, the razor requires that the blades cannot be disassembled after assembly to prevent the blades from being damaged and mixed during the disassembly process, which affects the use effect. The existing electric shavers, as shown in technical solution 201921527603.1, use a one-way snap-in method to assemble the bracket, while this solution uses press assembly. Different forces and pressing directions will cause instability in the use of the blade structure. Summary of the invention
