In one embodiment, the top is a flat end surface.

In one embodiment, the flanks extend along the arc of the cutting edge to the root, and the two flanks on the same tooth are symmetrical.

In one embodiment, the top surface is a rectangular-shaped structure and the root is substantially a chevron.

In one embodiment, two mounting holes are symmetrically arranged in the middle of the cutter body, a positioning hole is arranged between the two mounting holes, and the positioning hole is close to the root.

In one embodiment, the positioning hole is wide in the middle and narrow at two ends.

In one embodiment, three mounting grooves are formed in one side of the cutter body, and the width of the mounting groove in the middle is larger than that of the mounting grooves on two sides.

The hair-cutting machine is different from the conventional linear type cutting edge by the inwards-concave arc-shaped cutting edge structure, can effectively increase the hair feeding amount, improves the hair cutting efficiency, shortens the hair cutting time, improves the hair cutting efficiency, and is convenient for cleaning broken hair.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention.

Therefore, the detailed description of the embodiments of the present invention provided below in connection with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention, and all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive efforts shall fall within the scope of the present invention.

The terminology used herein is for the purpose of describing embodiments only and is not intended to be limiting and/or limiting of the utility model. It is to be understood that the terms "front", "back", "left", "right", "up", "down", and the like, are used in an orientation or positional relationship as shown in the drawings, or as would be conventionally found in use of the products of the present invention, or as would be conventionally understood by one skilled in the art, and are used merely for convenience in describing and simplifying the description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, configuration and operation in a particular orientation, and are not to be construed as limiting the present invention.

Hereinafter, an embodiment according to the present invention is described in detail with reference to fig. 1 to 3.

A blade for hair removal according to one embodiment of the present invention is typically used in conjunction with an electrically powered hair clipper for cutting hair, such as hair, in a repetitive transverse motion with a corresponding moving or stationary blade to thereby provide a cutting action.

In one embodiment, the blade mainly comprises a blade body 100 and a cutter tooth 200, wherein the blade body is assembled on a hair clipper for use, and the cutter tooth performs cutting action on hair.

Specifically, two mounting holes 110 are formed in the cutter body 100, the two mounting holes 110 are symmetrically located in the middle of the cutter body, a positioning hole 120 is formed between the two mounting holes 110, the positioning hole 120 is close to the root portion 250, the positioning hole 120 is wide in the middle, narrow in two ends, rectangular in the middle, isosceles trapezoid-shaped in two ends, and is matched with a clipper for assembly.

Specifically, three mounting grooves 130 are formed in one side of the cutter body 100, the width of the mounting groove 130 in the middle is greater than the width of the mounting grooves 130 in the two sides, and the width of the mounting groove in the middle is substantially equal to the transverse length of the positioning hole, so that the mounting grooves are matched with each other for use.

In one embodiment, a plurality of cutter teeth 200 are disposed on the other side of the cutter body 100, a tooth gap 300 is disposed between two adjacent cutter teeth 200, each cutter tooth 200 includes a top portion 210, cutting edges 220 located on both sides of the top portion 210, a top surface 230 extending from the top portion 210 toward the cutter body 100, side surfaces 240 located on both sides of the top surface 230, and a root portion 250 located at the tail end of the top surface 230, the cutting edges 220 are arcs recessed inwards, and the two cutting edges 220 located on the same cutter tooth are combined to form a substantially herringbone structure, thereby increasing the hair advancing amount, improving the cutting efficiency, and shortening the hair cutting time.

Specifically, the top 210 is a flat end surface, the side surfaces 240 extend to the root 250 along the arc structure of the blade 220, two side surfaces 240 on the same cutter tooth 200 are symmetrical, that is, the side surfaces are formed by stretching the structure of the blade 220 to the root, that is, the side surfaces are also concave arc surface structures, the cross section of the side surfaces is consistent with that of the blade structure, correspondingly, the top surface 230 is a rectangular structure, the root 250 is basically in a herringbone shape, and the root, the side surfaces, the blade and the top surface are combined to form a complete cutter tooth structure.

It should be noted that in the present invention, the connection modes not described between the components may all be connection modes commonly used in the field.

The scope of the present invention is defined not by the above-described embodiments but by the appended claims and equivalents thereof.
