Description

  The present invention relates to a kind of electric hair clipper cutter, and more particularly to a cutter structure that has a low cutting resistance and can cut hair smoothly and smoothly.

  Generally, the cutter of the electric clipper is provided at the front end of the main body, and the cutter is configured by a fixed cutter provided below and a movable cutter provided so as to overlap therewith and connected to a swing seat. The movable cutter forms a reciprocating motion to the left and right when the swing seat is driven by a motor in the main body, and forms a reciprocating motion so that the position of the movable cutter is shifted from the fixed cutter to cut the hair.

  Usually, the front end of the movable cutter is composed of a plurality of teeth A and is formed in a sawtooth shape, and as shown in FIGS. 1 and 2, the side of each tooth A is in contact with the hair C and an edge B that cuts the hair. It is said.

  The known electric hair clipper cutter shown in FIGS. 1 and 2 has a straight line with an edge B slightly inclined when viewed from the cross section, and is close to the vertical. When generating a shearing force by moving to the edge, the edge B and the hair form a substantially surface contact, and the contact area is large and the resistance is increased. And the hair becomes smooth and difficult to cut quickly. In this situation, it is easy to form a pinch of the hair, or if the hair is severely cut by pulling, the hair is liable to be damaged, the cutting effect and speed are greatly reduced, and the teeth are easily damaged. Since the hair cannot be easily cut, the cutting time is increased, the motor is overheated due to excessive load, the clipper is quickly worn out, and the service life is shortened. Thus, since the well-known electric hair clipper does not meet a user's request, improvement is calculated | required.

  The main object of the present invention is to provide a cutter for an electric hair clipper having a small cutting force and a good cutting effect that can smoothly and smoothly cut the hair.

  Another object of the present invention is to provide an electric hair clipper cutter that can easily cut hair and extend the service life of the hair clipper.

  A further object of the present invention is to provide an electric hair clipper cutter that can prevent the movement of hair, cut a relatively large amount of hair, and increase the cutting speed.

  The cutter of the electric hair clipper of the present invention includes a cutter set at the front end of the body of the electric hair clipper, and the cutter set includes a fixed cutter and a swing seat connected to the movable cutter, and a plurality of cutters are provided at the front end of the fixed cutter and the movable cutter. In the electric clipper cutter, the swing seat is driven by a motor inside the main body and the movable cutter reciprocates and moves with respect to the fixed cutter, the lower edge of both sides of the tooth of the movable cutter The position is characterized in that an outer expansion surface having a sharp crossing angle is provided so as to extend outward from the top to the bottom.

  In the present invention, a plurality of teeth are provided at the front ends of the movable cutter and fixed cutter of the electric hair clipper, and an edge is formed on the side of each tooth of the movable cutter to cut hair, and the lower position of the edge is removed from the top to the bottom. Stretching in the direction to form an outer extension surface with a sharp crossing angle, so that when the movable cutter moves out of position with respect to the fixed cutter and cuts the hair, the resistance to cutting can be greatly reduced. As a result, the hair can be cut sharply and sharply, and an excessive load on the motor can be prevented, and the service life of the electric hair clipper can be extended. In addition, the edge of the movable cutter can be formed in a form having a plurality of continuous concave grooves, thereby covering a relatively large amount of hair and preventing the hair from sliding outward, making the hair more rapidly and efficiently. Can be completed.

  3, 4 and 5 are a three-dimensional structure diagram of the present invention, a three-dimensional external view of the first embodiment of the movable cutter, and an enlarged three-dimensional view of a single tooth. A plurality of triangular sawtooth teeth 1 are provided at the front end of the movable cutter 22, and edges 13 are provided on both sides of each tooth 1 so as to contact the hair and cut the hair. See also FIG. 6 is a cross-sectional view taken along the line A-A 'of FIG. As can be seen from the cross section, the upper stage position of the edge 13 is in a straight line state, and the lower stage position is extended outwardly in an arc shape from the top to the bottom, and the outer expansion surface 12 having a sharp transverse angle is formed. . A plurality of arc-shaped continuous concave grooves 14 are provided on the edge 13, and the continuous concave grooves 14 are extended outward in an arc shape at the lower stage of the edge 13, and a wave-shaped arc surface is formed at the lower stage of the edge 13. Is forming.

  Since the outer extension surface at the lower end of the edge 13 forms a sharp cutting angle, the outer extension surface at the lower end of the edge 13 is moved when the movable cutter reciprocates horizontally and cuts the hair 2 as shown in FIG. 12 forms a sharp crossing angle, the area of contact with the hair is reduced, and the resistance force received by the entire edge 13 is greatly reduced, so that the hair 2 can be cut sharply and the cutting speed is greatly increased. To do. Since the hair 2 can be rapidly cut and there is no need to pull the hair 2, the appearance effect of the hair cutting is better than the conventional one, and the hair 2 can be prevented from being damaged and the edge is not easily damaged. When the hair 2 is sharply and smoothly cut, the motor 11 in the machine body is also operated smoothly, so that an excessive load can be prevented, thereby extending the service life of the motor.

  When the hair 2 is cut, the above-mentioned arc-shaped continuous concave grooves 14 can cover and contain a relatively large amount of hair, and the hair can be prevented from sliding outward during cutting. Thereby, a large amount of sharp hair cutting is achieved by the outer expansion surface 12 having the sharp cutting angle described above, and the hair cutting speed and efficiency are further improved.

  8 and 9 show a second embodiment of the present invention. The thickness of the movable cutter 22 can be changed depending on the strength of the material, the edge 13 has an arc line extending outward from the top to the bottom, and a sharp transverse angle is formed in the lower part of the edge 13. The outer expansion surface 12 provided is formed, the area of contact with the hair 2 is reduced, and the cutting resistance is reduced.

  10 and 11 show a third embodiment of the present invention. When the thickness of the cutter is smaller, the edge 13 is linearly extended from the top to the bottom, and the outer extended surface 12 at the lower end forms a sharp cutting angle so that the hair 2 can be cut rapidly.

  12 and 13 show a fourth embodiment of the present invention. The upper stage of the edge 13 has a straight line shape from the top to the bottom, and the lower outer expansion surface 12 has a straight line shape extending outward from the top to the bottom, thereby reducing the area of contact with the hair 2. Provide a cutting angle with less resistance.

  14 and 15 show a fifth embodiment of the present invention, in which the upper stage of the edge 13 has an arc shape and the lower outer expansion surface 12 has a straight line extending outward.

  Taken together, the present invention achieves the purpose of the present invention by reducing the resistance at the time of hair cutting significantly by the sharp crossing angle formed by the outward extending surface 12 extending outwardly at the lower end of the edge 13. It is possible to provide a cutter that can cut hair 2 rapidly and smoothly, and therefore the practical value of the present invention is clear.

  The foregoing is a description of the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification or change in detail that may be made based on the present invention shall fall within the scope of the claims of the present invention.
