AI Technical Summary
Existing straight-line blades are inefficient and provide a poor user experience when trimming the recessed areas around the chin and lips, and are also costly to manufacture.
The curved blade mesh is shaped by bending with a mold and fixed by injection molding or welding to form a horizontally full circle and vertically elliptical curved blade mesh structure. This ensures that the trimming area does not obstruct the skin, and the reciprocating motion of the blade holder is used to cut the hair through a return spring and a moving blade holder.
It improves pruning efficiency and user experience while reducing processing costs.
