Description

Hairdressing scissor blade

Technical Field

The invention relates to a hairdressing tool, in particular to a hair scissors blade.

Background

Most of the existing hair scissors in the market have a design that can conveniently replace the cutter head 90. referring to fig. 8-9, the cutter head 90 is composed of an upper movable cutter 91 and a lower fixed cutter 92, the upper movable cutter 91 is mainly matched and positioned by a spring 93, when the external electric power is used for driving the hair scissors to operate, the movable cutter 91 can slide left and right to match with the cutter teeth of the fixed cutter 92 for cutting hair, and when the electric power stops supplying, the movable cutter is elastically reset by the spring;

when the moving blade 91 slides, the moving blade 91 and the fixed blade 92 generate a large-area contact surface 94, and further generate friction and high-temperature loss problems, but most users only add lubricating oil to slow down the friction between the two blades, so that although some improvement is obtained, the problem is that the lubricating oil needs to be regularly supplemented to maintain, and the problem is not solved in practice;

in addition, the cut hair fragments are often stuck between the movable blade 91 and the fixed blade 92 during the use, so that a solution for reducing the loss between the movable blade 91 and the fixed blade 92 and keeping the smooth operation is still urgently needed.

Disclosure of Invention

The present invention is directed to a hair clipper blade that solves the above-mentioned problems.

In order to solve the technical problems, the invention provides the following technical scheme: a hair clipper blade comprises a cutter set, wherein the cutter set comprises a fixed cutter with a plurality of cutter teeth and a movable cutter with a plurality of cutter teeth, the fixed cutter is fixed in a cutter head, the movable cutter is close to the fixed cutter and can transversely slide in a reciprocating mode to form cutting, the cutter teeth are inwards sunken to form an oil groove, a first thin wall and a second thin wall can be formed on the periphery of the cutter teeth, the two thin walls can enable the movable cutter to slide and rub the contact area of the fixed cutter to be reduced, high temperature and noise caused by cutting are reduced, and cut hair can be discharged out of the cutter set along the first thin wall and the second thin wall through the oil groove.

Furthermore, the width of the movable knife is smaller than that of the fixed knife.

Compared with the prior art, the invention has the following beneficial effects: the cutter set is designed into the fixed cutter and the movable cutter with a plurality of cutter teeth, the cutter teeth are inwards sunken to form an oil groove, after the thin wall at the periphery of the cutter teeth is formed, when the movable cutter is matched with the fixed cutter to perform left and right sliding shearing actions, only the thin walls of the two cutters can be contacted, so that the temperature can be greatly reduced through the reduction of the contact area due to the high temperature generated by friction, the use amount of lubricating oil can be greatly reduced if lubricating oil needs to be added to the thin wall to reduce the friction situation of the two cutters, and cut hair can be discharged out of the cutter set along the first thin wall or the second thin wall by the oil groove, so that the problems of high temperature, structural loss and subsequent cleaning troubled by the prior art can be solved.

Detailed Description

The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

This best possible embodiment is generally in accordance with the invention and will be described in detail with reference to FIGS. 1-7 to enhance the understanding of the invention;

the invention relates to a hair clipper blade, which mainly comprises a blade set 20, wherein the blade set 20 comprises a fixed blade 22 with a plurality of blade teeth 21 and a movable blade 23 with a plurality of blade teeth 21, the fixed blade 22 is fixedly locked in a blade head 10 by matching with a screw, and the blade head 10 is detachably arranged on the hair clipper for convenient use;

the movable blade 23 is closely adjacent to the fixed blade 22 and is fixedly arranged in the blade head 10 through a corresponding fastener and an elastic component, so that the movable blade 23 can transversely slide back and forth to form a shearing action.

It can be seen that the stationary knife 22 and the movable knife 23 in the knife set 20 are provided with a plurality of knife teeth 21 and connected with each other, the knife teeth 21 are recessed inwards to form an oil groove 30, so that the periphery of the knife teeth 21 forms a thin wall, the thin wall comprises a first thin wall 221 and a second thin wall 231, and the design reduces the manufacturing materials and cost of the stationary knife 22 and the movable knife 23, and further reduces the overall mass;

referring to fig. 7, it can be seen that in the oil grooves 30 of the fixed blade 22 and the movable blade 23, because the hair 50 cut by the blade assembly 20 driven by power will fly around, and the first thin wall 221 and the second thin wall 231 are covered with lubricating oil, the hair 50 will slide into the oil grooves 30 between the fixed blade 22 and the movable blade 23, so that the hair 50 can be discharged to the outside of the blade assembly 20 more easily, thereby maintaining the smooth operation of the blade assembly 20, and not being caught between the fixed blade 22 and the movable blade 23 like the excessive hair 50 in the prior art structure, thereby also reducing the burden of the user for maintenance.

Referring to fig. 6, the stationary blade 22 is facing upward, the movable blade 23 is facing upward to show the second thin wall 231, the patterns of the first thin wall 221 of the fixed knife 22 and the second thin wall 231 of the movable knife 23 are respectively marked by different marks and then are overlapped, therefore, when the movable knife 23 is mounted on the knife head 10 for use, it can be seen that the area of the contact surface 40 of the fixed knife 22, which is rubbed by the movable knife 23 in a sliding manner, is relatively reduced, and by comparing with the contact surface 94 in the prior art structure diagram 9, the contact area between the two knives can be obviously reduced, so that the friction force between the two knives of the knife group 20 is reduced, and when the friction of the contact area is reduced, the noise generated by the operation of the knife group 20 can be reduced, and the blade parts of the fixed knife 22 and the movable knife 23 can also form a three-dimensional blade to reduce the shearing resistance and improve the shearing efficiency.

In summary, in the barber scissors blade according to the embodiment of the present invention, the knife set 20 is divided into the fixed knife 22 and the movable knife 23, the teeth 21 of the two knives are recessed inward to form the oil groove 30, so that the first thin wall 221 and the second thin wall 231 are formed on the periphery of the teeth 21 of the two knives, and the contact surface 40 of the fixed knife 22, which is rubbed by the movable knife 23 in a sliding manner, is reduced, by virtue of the design of the oil groove 30, the lubricating oil can be distributed uniformly, the consumption of the lubricating oil can be avoided from unnecessary waste, the resistance between the knife sets 20 can be further reduced by the oil groove 30, the load of the motor inside the overall structure is reduced, the shearing efficiency and the battery life can be significantly improved, the manufacturing materials and the weight of the knife set 20 can be further reduced, and the high temperature problem caused by the shearing friction can be.

The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
