Multifunctional small rotary shaving assembly

Abstract

The invention discloses a multifunctional small rotary shaving assembly. The multifunctional small rotary shaving assembly comprises a cutter head cover and a movable cutter assembly, wherein the movable cutter assembly comprises a movable cutter and a support used for fixedly holding the movable cutter, the cutter head cover comprises a cover head and a cover body which are integrated up and down, the cover head comprises a cover top and a cover wall connected to the outer side of the cover top, the cover top and the cover wall define a cutting cavity for the movable cutter to rotate inside,a plurality of hair inlet grooves communicating with the interior and the exterior of the cover head are formed in the cover head in the circumferential direction, the hair inlet grooves stretch across the cover wall from the cover top and longitudinally penetrate through the cover top and transversely penetrate through the cover wall at the same time, and a horn-shaped hair guide opening which corresponds to the hair inlet grooves and is used for guiding hair into the hair inlet grooves is formed in the turning connection position between the cover top and the cover wall. The multifunctionalsmall rotary shaving assembly has the advantages of being simple in structure, good in hair inlet effect, high in shaving efficiency, safe in shaving and capable of being applied to eyebrow trimming,nasal hair trimming, head lettering and carving and the like at the same time.

Description

【Technical field】 [0001] The invention relates to a multifunctional small rotary shaving assembly. 【Background technique】 [0002] The human body has body hair in many parts. With the diversification of people's pursuit of beauty today, there are eyebrow trimmers, nose hair trimmers, and patterns carved on the top of the head by shaving hair, etc., which gave birth to a variety of shaving hair. A shaving tool for cutting different parts of the body. [0003] There are hand-shaving eyebrow razors for eyebrow trimmers. When you trim your own eyebrows, you need to shave your eyebrows in the mirror, and because the skin surface is uneven, you need to scrape hard with your hands. It is difficult to control the range of shaving and the hand. When I use too much force, I either shave too much or don't shave enough, and even cut the skin. After the hand-scraping eyebrow trimming knife, a small rotary automatic cutting eyebrow trimming knife appeared. The eyebrow trimming knife has...

AI Technical Summary

Problems solved by technology

But above-mentioned first blade, second blade, blade spring, rotating shaft, the connecting installation structure of cutter head cover and its complexity, need to produce first blade, second blade, blade spring, rotating shaft separately, and first blade, the second The matching structure between the second blade, the blade spring and the rotating shaft is complicated, and the production cost of the mold and the like is high. When assembling, the first blade, the second blade and the blade spring need to be installed in the guide rail slot on the rotating shaft correspondingly. Hold the first blade and the second blade by hand to prevent the blade spring from popping them loose, and then slowly insert them into the cutter head cover. The production process is complicated and the convenience is poor.

[0005] For trimming nose hair, there are nose hair scissors, which are small scissors, and a small rotary automatic cutting nose hair knife has also been developed. The nose hair knife and eyebrow trimming knife have a similar structure, and both use a small radius knife head cover. , and a rotary cutting moving knife assembly is set in the knife head cover, but it is impossible to trim the nose hair with the eyebrow trimmer, because the nose hair grows on the inner wall of the nasal cavity and grows in a criss-cross pattern in the nasal cavity, the eyebrow trimmer knife head cover Nose hair can be effectively entered into it, so the head cover of the nose hair knife needs to be specially designed, such as the technical scheme shown in the application number CN200620131104. The small net-shaped blade that can extend into the nasal cavity, also called the knife head cover, forms the top surface through multiple bending units, and the multiple bending units form a nose hair suction port on the top surface, and two adjacent bending units A slit-type slot is formed, which communicates with the nose hair suction port, and a movable blade that can rotate and cut is arranged inside the bending unit, and the movable blade rotates and cuts along the side inner wall of the cutter head cover, and due to the The slots are narrow. In order to avoid the meat from being squeezed in, the width of the slots cannot be increased. The way of hair entry is basically that the nose hairs enter from the nose hair suction port in the middle, and then enter different slots for cutting.

Then when inserting the nostril, the nose hair opposite to the nose hair suction port is easier to enter and cut, while the nose hair protruding from the side wall of the nostril outside the nose hair suction port is difficult to enter the inside of the cutter head cover for cutting, and the hair entry efficiency is not good. it is good

And the moving knife assembly of the nose hair knife usually adopts a similar structure as in the application number CN201821817498, its structure and assembly process are complicated, and the manufacturing cost is high

[0006] And because the nose hair knife only has a side cutting position, the top surface is not cut and has a larger through hole (nose hair suction port), regardless of safety and cutting, it is usually only used for the inner cavity of the nasal cavity. body hair shaving

[0007] And lettering and engraving patterns etc. on the head, usually just adopt haircutting lettering knife, its biggest difference with general haircutting scissors is exactly that the head width of its haircutting is smaller, so that small-scale haircutting engraves, as application number CN201320724635.7, The name is a technical scheme shown in a cutting head of a haircut scissors lettering knife. The biggest advantage of this kind of cutting head is its simple structure, but because it cuts by swinging, the cutting width it can achieve is limited If it is made so small like a rotary nose hair cutter or an eyebrow trimmer, the lines of the lettering strokes or patterns will be limited to a large size, which cannot meet the needs of use well

Moreover, when using a haircutting knife, you need to push it forward to shave. It is inconvenient to do it yourself or engrave a pattern. Usually, you can only shave it through someone else.

[0008] As mentioned above, when consumers have shaving needs in multiple parts such as nose hair, eyebrows, lettering, etc., they need to buy different types of shaving tools. One is expensive, and the other needs to occupy more living space, which is not convenient enough. Although the concept of each shaving tool is novel, due to its defects of one kind or another, the actual use effect is not good, and the social response is not good, which leads to the current market promotion is limited
