Description
Technical Field
The utility model relates to a razor, especially a reciprocating type razor's tool bit.
Background
The traditional shaver has a lamellar outer cutter, a plurality of small holes in circular or other shapes are formed in the outer cutter, an inner cutter is installed below the outer cutter, the top surface of an inner cutter unit is arc-shaped, the outer cutter is bent into an arch shape along the arc-shaped inner cutter, and the inner cutter is driven by an internal motor through a transmission device to perform cutting action. When the shaver is attached to the face, beard can be quickly cut off by the inner cutter after the beard is extended into the shaver from the small hole of the outer cutter, so that the aim of shaving is fulfilled. The small hole is easy to insert for short beard, but some curled beard or longer beard are difficult to insert into the small hole, so that the long beard is often cut short before shaving, or the long beard which is not shaved is cut short after shaving, so that the shaver has the defect of difficult long beard shaving, and the effect of shaving the long beard and the short beard as much as possible at one time cannot be achieved. In addition, the existing shaver often has the phenomenon of beard beating, namely, the beard is torn between the cutting components, so that the skin feel is greatly reduced.
Disclosure of Invention
The utility model provides a compact structure, skin feel are good, can reach once shave long beard or the reciprocating type razor's of the beard and the short palpus of curling.
In order to solve the technical problem, the utility model discloses a following technical scheme: the cutter head of the reciprocating shaver comprises a cutter head shell, one or more shaver unit components arranged on the cutter head shell, wherein the shaver unit components comprise a movable cutter frame which is arranged in the cutter head shell and is driven by a driving shaft to do transverse reciprocating motion, a movable cutter which is arranged on the movable cutter frame and can do reciprocating motion along the length direction in the using process, and a static cutter which is bent by a thin plate to be in a long strip shape and is transversely arranged above the movable cutter, the shaver unit components comprise at least one side cutter unit component which is arranged by the inner side wall of the shell, beard inlet long slotted holes in the skin-friendly cutting area of the side cutter unit component are transversely arranged in multiple rows, the long beard leading-in grooves are arranged at the junction of the transverse plane and the side vertical plane of the outer stationary knife, namely the long beard leading-in grooves are formed by connecting horizontal cut parts on the transverse plane and vertical cut parts on the side vertical plane, the horizontal cut parts and the vertical cut parts form an L shape, the horizontal cut parts and the vertical cut parts are V-shaped, trapezoidal, semi-elliptical or semicircular, the openings of the horizontal cut parts and the vertical cut parts are in butt joint, and the movable knife cutting edges of the side knife unit component corresponding to the long beard leading-in grooves are in a comb tooth shape.
As an improvement: and a spacing strip 8 is arranged between the beard advancing long slotted hole which is closest to the inner side wall of the shell and the beard advancing long slotted hole which is adjacent to the beard advancing long slotted hole, and the spacing strip enables the two adjacent rows to be arranged in a non-through mode with strip spacing.
As an improvement: the spacer belt is a sinking positioning groove, the sinking positioning groove extends along the length direction of the transverse surface and transversely penetrates the supporting areas at the left and right ends respectively, and limiting parts matched with the sinking positioning groove are arranged at the left and right ends of the cutter head shell respectively.
As an improvement: the side cutter unit component is in an inverted U-shaped notch shape corresponding to the movable cutter cutting edge of the short hair leading-in groove.
As an improvement: the long beard leading-in grooves are transversely and uniformly distributed along the length direction of the outer stationary knife.
The utility model provides a beneficial effect is: the long beard inlet slots in the inner side wall of the casing are long beard inlet slots with outward openings, and the long beard inlet slots in the adjacent rows are short beard inlet slots, so that the long and short beard inlet slots are reasonably distributed, and particularly, the long beard can enter the cutter head from the side or the outer side to be cut. The side cutter unit component is comb-shaped corresponding to the moving cutter cutting edge of the long beard leading-in groove, so that the long beard is a large cutting channel during cutting or after entering the cutter head, namely, compared with an arched cutting edge, a comb-shaped moving cutter area can form a beard tearing surface without a stand column and an outer static cutter, and is a straight falling type beard falling channel, thereby being very beneficial to cutting of long curled beards and greatly improving the shaving skin feel. The middle short beard cutting layout can shave beards completely at one time without frequently and repeatedly shaving at the same position.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
