The tooth edge of each static blade comb tooth is formed by the intersection of a horizontal plane and an inclined plane. The horizontal plane of each static blade comb tooth blade is on the same plane, and each static blade comb tooth is near the pivot side. A guiding lobe is provided at the edge of the tooth edge of each tooth, and a guiding bevel is provided on the surface of each guiding lobe that is in contact with the cutting edge of the moving blade. The cutting edge of the moving blade is guided by the guiding bevel and where the guiding bevel is located. The static blade comb tooth blade is cut together; it is characterized in that the blade of the moving blade is a linear blade and a blunt blade that is not easy to bruise the hair; or the blade of the moving blade is The tooth blades of the moving blade comb teeth arranged side by side and spaced apart are the sharp blades that can cut the hair, and the comb grooves between the adjacent movable blade comb teeth are not easy to bruise the hair. The blunt grooves, each of the movable blade comb teeth are arranged one by one with each of the static blade comb teeth, and the hair of the movable blade comb teeth is opened and closed toward the corresponding static blade comb teeth.

Further, in the aforementioned hair care scissors, the cutting edge angle of each of the static comb teeth is 10-65 °, preferably 54 °.

Further, in the aforementioned hair care scissors, the height of the guide lobes is 0.1 mm to 4 mm.

Further, in the foregoing hair care scissors, wherein the cutting edge of each static blade comb tooth edge is inclined from high to low starting from the side near the pivot, and the inclination angle of the cutting edge is 0.5-10 °.

Further, in the foregoing hair care toothbrush, a width of a horizontal plane on each of the static and comb tooth blades is 0.5 mm to 2 mm.

Further, in the foregoing hair care dental scissors, wherein an included angle between the guide slope and a horizontal plane is 0.2 to 5 °.

The advantages of the utility model are: the hair care toothbrush described in the utility model adopts two methods to prevent bruising of the hair, one is to set the linear moving blade blade to a blunt edge that is not easy to bruise the hair, and the other is The sharp moving blade blade is set to be composed of several moving blade comb teeth arranged side by side, so that the moving blade blade can avoid the hair entering the gap between the static blade comb teeth, so that the moving blade The blade of the blade is not easy to bruise the hair; after using any of the two methods, the hair care toothbrush can meet the requirement of not easily bruising the hair.

detailed description

The following further describes the present invention in detail with reference to specific embodiments and drawings.

As shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, and FIG. 5, the hair care scissors include: a movable blade 1 and a static blade 2, and the movable blade 1 and the static blade 2 are hinged through a pivot 3, On the trailing ends of the moving blade 1 and the static blade 2, a finger ring 4 for opening and closing the finger is provided. The hair of the moving blade 1 is opened and closed toward the blade of the static blade 2 to cut the hair. The blade of the blade 2 is composed of a plurality of tooth blades of the static blade comb teeth 21 arranged side by side. The tooth blades of each of the static blade comb teeth 21 are formed by the intersection of a horizontal plane 5 and an inclined plane 6. Each of the static blade comb teeth 21 tooth blades The horizontal plane 5 is all on the same plane, and the cutting edge angle α of each of the static blade comb teeth 21 is 10 to 65 °, preferably 54 °. The setting of the cutting edge angle of the static blade comb teeth 21 can make the blade edge The sharpening of the mouth makes it easier to cut the hair, and a guide lobe 22 is provided at each edge of each of the static blade comb teeth 21 near the pivot 3 side, and each guide lobe 22 and the movable blade 1 blade Each of the contact surfaces is provided with a guide bevel 23, and the cutting edge of the movable blade 1 is subjected to the guide bevel 23. Located rearwardly inclined surface 23 and the static blade guide comb-tooth edges 21 with shear collapse. Because the corners of the guide lobes 22 are narrow, hair is not easily caught between the guide lobes 22 and the blade of the moving blade 1, so it is difficult to pull the hair, so that the head of the hairdresser does not feel pain. The use of the guide lobes 22 with narrow corners for guiding can also greatly reduce the frictional force of hair cutting, making the hair cutting feel better. In this embodiment, the blade of the movable blade 1 is a linear blade and a blunt blade that does not easily bruise the hair. In addition, another structure of the movable blade 1 of the hair cutting scissors is shown in FIG. 6. The blade of the movable blade 1 is composed of a plurality of tooth edges of the movable blade comb teeth 11 arranged side by side and each movable blade comb teeth. The tooth blades of 11 are all sharp blades that can cut hair. The comb grooves between each adjacent movable blade comb teeth 11 are blunt grooves that are not easy to bruise the hair. In a relative arrangement, the hair of the movable blade comb teeth 11 is opened and closed toward the corresponding stationary blade comb teeth 21 to cut the hair.

In addition, as shown in FIG. 2, FIG. 3, and FIG. 5, the height a of the guide lobes 22 is 0.1 mm to 4 mm. If the guide lobes 22 are too low, the guide effect will not be achieved. If the guide lobes are too high, the guide lobes will be made. The top of the 22 is too sharp, posing a safety hazard. The blade edge of each static blade comb 21 tooth blade is inclined from high to low starting from the side close to the pivot axis 3, and the angle of inclination β of the blade edge is 0.5 to 10 °. The blade is inclined so that the hair can follow the direction of the blade close Escape, prevent excessive hair cutting, make the cutting marks inconspicuous, and achieve a seamless cutting effect. The width b of the horizontal plane 5 on each of the stationary blade comb teeth 21 is 0.5 mm to 2 mm. The included angle γ between the guide inclined surface 23 and the horizontal plane 5 is 0.2 to 5 °. If the angle of the guide inclined surface 23 is too small, the guiding effect will not be achieved. If the angle of the guide inclined surface 23 is too large, the friction force will be increased, and the shaving feel will be worse.
