Description

Double-cover beard-removing type hair trimmer

Technical Field

The invention relates to the field of hair trimming, in particular to a double-cover hair row beard type hair trimmer.

Background

Hair is an appendage of the skin and is an oblong cylindrical cuticle structure. The part of the hair which is exposed out of the skin surface is called hair shaft, the part which is buried in the skin is called hair root, and the tail end of the hair root is enlarged to be in a scallion head shape and is called hair bulb. Hair can be divided into two types, one is called long hair, such as hair, beard, axillary hair, and pubic hair; the other is short hair, such as eyebrow, eyelash, ear hair, etc. Hair trimmers commonly used in daily life are often used to trim long hair shafts such as hair and beard.

Beard, commonly known as beard, generally refers to hair growing on the male upper lip, chin, cheek or neck, and thus shavers are common hair trimmers. Males after puberty generally develop beard. Beards grow faster than hair, which is the result of androgenic action. And because the blood vessels of the beard growing part are distributed more than the blood vessels of the hair root, and the nutrients are easily obtained, the beard grows out in a short time after being scraped.

Some men like to hold beard, however, medical experts believe that beard growth should be shaved off in time because leaving long beard may affect health because of the characteristic of the beard to adsorb harmful substances. When people breathe, various harmful chemical gases can be discharged and can be remained on the beard. The atmosphere contains various heavy metal particles, and particularly in busy streets, lead emitted from automobile exhaust can be adsorbed by beard. Carcinogens contained in smoke given out by smokers also stay on beard. The skin of long beard has more oil secretion, and is difficult to wash away when face is washed with clean water at ordinary times, and the oil has the characteristic of sticking and accumulating dust.

The research shows that the shaving is beneficial to face cleaning, enables dead skin cells to fall off, can also enhance the muscle activity of the face and the chin, promotes local blood circulation and metabolism, is beneficial to eliminating facial wrinkles, and enables people to be young and beautiful.

Therefore, shaving beards are the personal cleaning activities common in daily life of most men nowadays, and shaving tools evolve continuously from old to old, and people pay more and more attention to convenience and comfort in shaving and cleaning from old shavers to manual shavers and then to electric shavers. At present, the electric shaver is taken as the mainstream of the shaver, and is more complex and various in style and wider in function coverage.

An electric shaver is a hair trimmer which utilizes electric power to drive blades and shave beard and temples, belonging to daily necessities commonly used by men in daily life. Electric shavers are classified into rotary type and reciprocating type according to the manner of blade motion. The former has simple structure, small noise and moderate shaving force; the latter has complex structure and large noise, but has large shaving force and high sharpness.

Existing electric shavers typically consist of a stainless steel mesh cap, inner blades, a micro-motor and a housing. The net cover is a fixed outer blade, and is provided with a plurality of holes into which beard can extend. The micro motor is driven by electric energy to drive the inner blade to move, and the beard extending into the hole is cut off by utilizing the shearing principle.

However, during use, the inner blade is continuously dulled, so that the cutting ability of the electric shaver is reduced. In the cutting process, the inner blade pulls the beard to move along the eyelet to influence the use experience of a user, even pulls the hair follicle of the user, a small wound surface is formed at the hair follicle of the beard seriously, bacteria easily invade to cause inflammation, such as folliculitis, sebaceous gland inflammation and the like, and scar can be formed after healing, so that the appearance is influenced, and great pain is caused.

In addition, the beard at the lip edge is positioned in a 'dangerous trigone' of the face, blood vessels at the part are communicated with a cavernous sinus in a cranial cavity, a wound surface is formed in the area and is invaded by bacteria, the bacteria easily enter the cranium through a vascular network to cause encephalitis or meningitis, and the afterfruit is not imaginable. In addition, when the common electric shaver is used, the beards can pass through the holes of the net cover in a messy manner, and the cutting of the beards by the inner cutter blade can be further influenced.
