Description

Technical Field

[0001] The utility model belongs to the technical field of electric shavers, in particular to a shaver head with a reserved beard length. Background Art

[0002] An electric shaver consists of a stainless steel mesh cover, inner blades, a micro motor and a housing. The mesh cover is a fixed outer blade with many holes on it, through which the beard can be inserted. The micro motor is driven by electrical energy to drive the inner blade to move, and the beard inserted into the hole is cut off by the shearing principle. Electric shavers can be divided into two types: rotary and reciprocating according to the action characteristics of the inner blade. The power sources used include dry batteries, storage batteries and AC charging.

[0003] In order to avoid cutting human skin due to the movement of the blade during shaving, the existing razors sold on the market usually have a relatively small size of the beard entry groove, resulting in a poor beard entry effect of the outer beard entry groove, and are only suitable for shorter beards. Longer beards cannot directly pass through the cutting holes into the inner wall of the mesh cover to be cut off by the blade. In addition, users currently need to keep their beards at a certain length, but existing razors cannot meet the needs of users during shaving. Utility Model Content

[0004] In view of this, the utility model provides a razor head with a reserved beard length suitable for beards of different lengths to meet industrial needs.

The plurality of inner beard inlet holes and the plurality of outer beard inlet holes are arranged in a ring shape. The inner beard inlet portion is concentrically arranged with the outer beard inlet portion, and the blade net body and the blade net support ring are spaced apart. When the blade net is mounted on the blade head limit frame, each of the top limit clamps corresponds to and abuts against one of the support frames, and the free end of the top limit clamp is clamped on the outer beard inlet portion, so that the top limit clamp limits the distance between the user's skin and the blade net, thereby avoiding cutting all of the user's beard.

[0006] Furthermore, the outer contours of the top limit clamps are both in an inverted "L" shape, and the outer contours of the bottom limit clamps are both in an "L" shape.

[0007] Furthermore, the gap of the inner hair entry hole is smaller than the gap of the outer hair entry hole.

[0008] Furthermore, the outer contour of each of the outer hair inlet holes is in a "V" shape, and the gap between each of the outer hair inlet holes increases gradually from one end of the outer hair inlet hole close to the inner hair inlet hole to one end of the outer hair inlet hole facing the support frame.

[0009] Furthermore, the inner hair inlet holes are all arranged obliquely, and each outer hair inlet hole is arranged along the radial direction of the blade net body.

[0010] Furthermore, the inner blade includes a cutter head body, an inner ring cutter head arranged on the cutter head body, and an outer ring cutter head arranged around the outer side of the inner ring cutter head.
