Technical Field

The invention relates to the application field of hair clippers, and in particular to a multi-blade cutter head for a self-service hair clipper.

Background Art

Self-service hair clippers are currently more common haircutting tools, mainly used for self-service haircutting by the elderly. They have a simple structure and are easy to operate. However, traditional self-service hair clippers currently have single-edged blades, which have low haircutting efficiency and may not cut hair cleanly. In addition, traditional hair clippers cannot cut long and short hair together, and need to replace the blade head, which is very troublesome. Therefore, a multi-edged blade head for self-service hair clippers is needed to solve this technical problem.

The outer rings of the moving blade and the stationary blade are provided with annular toothed cutting edges.

The movable blade has an assembly hole for assembling with the annular blade head, and the annular blade head has an assembly column adapted to the assembly hole. The annular blade head passes through the assembly hole of the movable blade through the assembly column and is connected to the driving component of the hair clipper. The movable blade moves synchronously with the annular blade head.

The stationary blade and the moving blade are in an up-and-down distribution structure, the outer diameter of the stationary blade is larger than the moving blade, and the inner diameter of the stationary blade is smaller than the moving blade.

The inner ring side wall of the stationary blade is provided with a bayonet for fixed assembly with the hair clipper, and the movable blade has a travel groove for the bolt to pass through.

The bottom end of the annular toothed blade of the static blade is provided with an arc-shaped boss.

Beneficial effects of the invention: The invention provides a multi-blade cutter head for a self-service hair cutter. By changing the traditional single-blade cutter head into a multi-blade cutter head, when in use, the contact area between the cutter head and the hair is larger, the inner or outer cutter head is convenient for cutting long hair, and the annular cutter head, that is, the middle net cutter, is convenient for cutting short hair and hair roots. It is more convenient to use, improves haircutting efficiency and neatness of haircutting, and is easy and quick to use, and is suitable for the elderly and people who need to shave short hair or shave their heads.

DETAILED DESCRIPTION

Embodiment 1, as shown in FIGS. 1 to 3, a multi-blade cutter head for a self-service hair clipper comprises a moving blade 100 and a stationary blade 200, wherein the moving blade 100 and the stationary blade 200 are both annular structures, wherein the moving blade 100 and the stationary blade 200 both have a center of a circle, and the center of the moving blade 100 and the stationary blade 200 coincide with each other, and the outer rings of the moving blade 100 and the stationary blade 200 are provided with an annular toothed blade edge a with the center of the circle as the center point, and the moving blade 100 and the stationary blade 200 are assembled to form a cavity, wherein an annular cutter head 300 with the center of the circle as the center point is provided in the cavity, and the stationary blade 200 is provided with mesh holes 210 evenly distributed with the center of the circle as the center point, and the working principle of haircutting is the same as that of a traditional hair clipper, wherein the moving blade 100 and the stationary blade 200 cooperate to achieve haircutting, and the advantage of providing multiple cutter heads is that during haircutting, the multiple cutter heads can fully contact the hair, and the haircutting efficiency and the neatness of haircutting can be effectively improved.

The outer rings of the moving blade 100 and the stationary blade 200 are provided with an annular toothed cutting edge a. In this embodiment, matching annular toothed cutting edges a are provided on the outer rings of the moving blade 100 and the stationary blade 200.

The movable blade 100 has an assembly hole 110 for assembly with the annular blade head 300, and the annular blade head 300 has an assembly column 310 adapted to the assembly hole 110. The annular blade head 300 passes through the assembly hole 110 of the movable blade 100 through the assembly column 310 and is connected to the driving assembly of the hair clipper. The movable blade 100 moves synchronously with the annular blade head 300. The assembly structure of the movable blade 100, the annular blade head 300 and the driving assembly of the hair clipper is basically the same as the assembly structure of the traditional hair clipper, and no further elaboration is made on this.

The stationary blade 200 and the moving blade 100 are in an upper and lower distribution structure. The outer diameter of the stationary blade 200 is larger than that of the moving blade 100, and the inner diameter of the stationary blade 200 is smaller than that of the moving blade 100. This solution is convenient for processing and assembly, and is preferably adopted.

The inner ring side wall of the stationary blade 200 is provided with a bayonet 220 for fixing and assembling with the hair clipper. The movable blade 100 has a travel groove 120 for the bolt to pass through. The travel groove 120 is an arc-shaped long groove that fits the annular blade body and is mainly used to limit the rotational travel of the movable blade 100.

The bottom end of the annular toothed blade a of the static blade 200 is provided with an arc-shaped boss 230. The function of the arc-shaped boss is to prevent the skin from being scratched during haircutting. That is, when the hair clipper is pushed on the scalp, the arc-shaped boss 230 at the end of the blade head first contacts the scalp to prevent the toothed blade tip from scratching the scalp.

Embodiment 2, as shown in FIG. 4 , is different from Embodiment 1 in that in this embodiment, an annular toothed edge a is provided on the inner ring of the moving blade 100 and the stationary blade 200 .

Embodiment 3: The difference between this embodiment and embodiments 1 and 2 is that in this embodiment, the inner ring and the outer ring of the moving blade 100 and the stationary blade 200 are both provided with annular toothed cutting edges a.

The present invention provides a multi-blade cutter head for a self-service hair cutter. By changing a traditional single-blade cutter head into a multi-blade cutter head, when in use, the contact area between the cutter head and the hair is larger, the inner or outer cutter head is convenient for cutting long hair, and the annular cutter head, that is, the middle net cutter, is convenient for cutting short hair and hair roots. It is more convenient to use, improves haircutting efficiency and neatness of haircutting, and is convenient and quick to use, and is suitable for the elderly and people who need to shave short hair or shave their heads.
