Description

Technical Field

[0001] The utility model relates to the technical field of shavers, in particular to a three-ring blade net. Background Art

[0002] The blade head of a razor includes a mesh cover connected to the razor body and a blade rotating inside the mesh cover. The mesh cover can also be called a fixed blade head, and the blade is called a movable blade head. After the fixed blade head fits against the skin, beard and other hair pass through the fixed blade head, and the movable blade head rotates relative to the fixed blade head to cut the beard. Therefore, the ability of the fixed blade head to guide the beard through is the basis for whether the razor can remove the beard cleanly.

[0003] The existing blade net generally captures the beard by setting straight grooves, but the existing straight grooves are arranged too evenly, and because the beard growth position and angle are irregular, the probability of the beard entering the straight groove is reduced, thereby reducing the shaving efficiency.
