Description

Movable knife of small-sized rotary shaving assembly

[ technical field ] A method for producing a semiconductor device

The utility model relates to a small-size rotatory subassembly of shaving that moves sword.

[ background of the invention ]

The human body has body hair at many parts, and with the diversification of the pursuit of beauty of people nowadays, eyebrows, nose hairs, characters and patterns are carved on the top of the head through hair shaving, and the like, so that a plurality of hair shaving tools for shaving and cutting body hair at different parts are created.

The hand-scraping type hand-eyebrow-shaving knife for eyebrow-shaving needs to scrape eyebrows by looking into a mirror when an individual trims the eyebrows, and the hand needs to scrape the eyebrows due to uneven skin surface, so that the shaving range is not controlled, and the hand is not shaved much or not when the force is not controlled well, even the skin is cut. The utility model provides a small-size rotation type automatic cutout's eyebrow knife has appeared after the eyebrow knife is scraped to the hand, the last eyebrow knife head of repairing that has of eyebrow knife, like application number CN201821817498, the name is the shown technical scheme in the eyebrow trimmer tool bit device, thereby cover first blade and second blade through the less tool bit cover of the type of being convenient for of a radius, set up many straight flute profile's sword seam confession eyebrow entering along the circumferencial direction on the tool bit cover, drive first blade and second blade at tool bit cover internal rotation through the rotation axis and cut the eyebrow. Because the eyebrow has certain length and compliance, all adopt the straight flute structure to advance the hair usually, also can set up the pore that advances that one by one independently simultaneously at the top, the hair root that supplies to cut off most length gets into the cutting, like patent CN 201821817498's tool bit cover structure, and because the straight flute structure supplies skin extrusion to get into more easily, in order to guarantee the security, do not cut the skin, the width of straight flute structure need be done less, the straight flute width is little then its hair inlet is tiny to cause into the hair difficulty, lead to the hair efficiency of advancing of current automatic eyebrow knife of rotation type extremely poor.

In the conventional rotary automatic eyebrow plucker, in order to make the blades in the blade case adhere to the inner wall of the blade case to ensure the cutting sharpness, as shown in patent CN201821817498, the first blade and the second blade are usually movably mounted on a rotating shaft, and the first blade and the second blade are pushed out to the side by the elasticity of a blade spring to make the first blade and the second blade push against the inner wall of the blade case, and usually the head of the blade case is provided with a tapered structure, and both the top plane and the tapered side have cutting areas, after a long service time, the blades have different degrees of abrasion between the top cutting edge and the side cutting edge, and the top cutting edge and the side cutting edge of the blades can be respectively compensated by the lateral elastic pressing of the blade spring and the upward elastic pressing of a lifting spring to ensure the cutting sharpness. However, the connection and installation structure of the first blade, the second blade, the blade spring, the rotating shaft and the blade cover is complex, the first blade, the second blade, the blade spring and the rotating shaft need to be produced separately, the matching structure between the first blade, the second blade, the blade spring and the rotating shaft is complex, the production cost of a die and the like is high, when the assembly is carried out, the first blade, the second blade and the blade spring need to be correspondingly installed in the guide rail clamping groove on the rotating shaft, the first blade and the second blade need to be pinched by hands to prevent the blade spring from being ejected out and loosened and collapsing, and then the blade spring is slowly inserted into the blade cover, so that the production process is complex and the convenience is poor.

The nose hair scissors for trimming the nose hair are small scissors, and a small rotary automatic cutting nose hair knife is developed, wherein the nose hair knife is structurally similar to the nose hair knife, a knife head cover with a smaller radius is adopted, a movable knife component for rotary cutting is arranged in the knife head cover, but the nose hair knife cannot be used for trimming the nose hair, the nose hair is grown on the inner wall of a nasal cavity and is criss-cross grown in the nasal cavity, and the knife head cover of the nose hair knife cannot effectively allow the nose hair to enter the nose hair knife, so the knife head cover of the nose hair knife needs to be specially designed, for example, the technical scheme shown by the application number CN200620131104.7 and named as the nose hair knife, the nose hair knife head is usually a mesh cover type blade with a smaller radius and capable of extending into the nasal cavity, also called as the knife head cover, the top surface is formed by a plurality of bending units, the plurality of bending units form a nose hair suction inlet on the top surface in a surrounding mode, and two adjacent bending units form a slit type, the slot is communicated with the nasal hair suction inlet, the inner side of the bending unit is provided with a movable blade capable of rotating for cutting, the movable blade rotates for cutting along the inner wall of the side surface of the cutter head cover, and the slit type slot is narrow, so that the width of the slot can not be large in order to avoid meat extrusion, and the hair feeding way is that the nasal hair enters from the nasal hair suction inlet in the middle and enters different slots respectively for cutting. When the cutting tool is inserted into the nostril, the nose hair opposite to the nose hair suction inlet can be easily cut, while the nose hair which laterally extends out of the nose hair suction inlet on the side wall of the nostril is difficult to enter the tool bit cover for cutting, and the hair feeding efficiency is also poor. And the moving blade component of the vibrissa cutter usually adopts a similar structure as that in application No. CN201821817498, and the structure and the assembly process are complex, and the manufacturing cost is high.

Since the vibrissa cutter has only a side cutting position, the top surface is not cut and has a large through hole (a vibrissa suction opening), and it is also generally used only for shaving body hairs of an inner cavity portion such as a nasal cavity regardless of safety and cutting performance.

The hair clipper head has the greatest advantage of simple structure, but because the hair clipper head is used for cutting through swinging, the cutting width of the hair clipper head is limited, and the hair clipper head cannot be made as small as a rotary nose hair clipper or a eyebrow shaping clipper, the lines of the carved strokes or patterns are limited to be larger, and the using requirements cannot be well met. When the hair cutter is used, the hair cutter needs to be pushed forwards to shave hairs, and the hair cutter is inconvenient to carve the hairs or pattern by hands and can only shave hairs by other people.

As mentioned above, when a consumer has a shaving demand on a plurality of parts such as nose hair, eyebrow, lettering, etc., the consumer needs to purchase different types of shaving tools, one shaving tool has high cost, the other shaving tool occupies a large living space, and the shaving tools are inconvenient, and although the concepts of the shaving tools are novel, the practical use effect is not good due to the defects, the social reverberation is not good, and the market popularization is limited at present.

What we are engaged in is a new design that can simultaneously meet the use requirements of nose hair, eyebrow, head lettering, etc., and at the same time solve the above-mentioned drawbacks of the shaving tools.
