Description

Comb capable of generating micro-current

Technical Field

The utility model relates to the technical field of combs, in particular to a comb capable of generating micro-current.

Background

Alopecia is now a very common phenomenon, especially with more and more youth, and more young people have added the "mediterranean" line, and the annoyance of baldness as it comes "is not only a facial impairment, but also a mental strike. The reasons for alopecia are considered, and the most important reason is that collagen is lost with age and the blood circulation of hair follicles is impaired, and the hair is not sufficiently nourished.

The existing hair regeneration nursing methods comprise hair growth liquid medicine, red light treatment and electric stimulation treatment. The hair-growing liquid medicine is used as a hair regeneration nursing method, and whether various components have side effects or not is left aside, so that the hair-growing liquid medicine is slow to absorb and is also a short board with low efficiency; the red light treatment also has the defect of long effective time; the effective time of the electrical stimulation treatment is short, and the effect is obvious.

However, for the existing products of electrical stimulation therapy, such as the micro-current technology, the low-voltage and low-frequency technology is adopted, the resistance value of the skin of a human body is large, the sensing current cannot be obtained when the skin is directly used, and the sensing current is the minimum current which can cause any feeling of a human body through the human body under a certain probability and is called as the sensing current. The initial feeling of human to current is slight tingling and feelings of weak acupuncture; a large number of experimental data have shown that the perceived current is not the same for different people. The sensing current is related to factors such as individual physiological characteristics and the contact area of the human body and the electrode. The perceived current corresponding to a probability of 50% is about 1.1 ma for adult men and about 0.7 ma for adult women. The sensing threshold is set at 0.5 ma and is independent of time factors. The body impedance is not a pure resistance and is mainly determined by the body resistance. The body resistance is not a fixed value either. It is generally accepted that dry skin has a relatively high resistance at low voltage, about 10 kilo ohms. When the voltage is 500-1000V, the resistance of human body is reduced to 1000 ohm.

Therefore, the low-voltage low-frequency micro-current technology of the existing electrical stimulation treatment product must be matched with conductive media such as conductive gel and the like to be used for reducing the resistance value of the surface of the skin so as to obtain the sensing current. There is no way to use the skin sensitive to chemicals, or it is inconvenient to apply the conductive gel on the skin of the head.

The micro-current technology is well developed in the field of medical care, and can penetrate through the body surface skin (epidermal layer) to reach the dermis layer, so that the generation of collagen is promoted; the shrinking and heating effect generated by the micro-current stimulation causes the impurities such as acid substances, triglyceride, cholesterol and the like adhered on the vessel wall to be decomposed and stripped, the impurities are metabolized out of the body, the blood is purified, the elasticity and smoothness of the vessel are restored, the functions of promoting blood circulation and improving metabolism are achieved, and the hair regeneration nursing can be completed.

The conductive part of some existing electrical stimulation treatment products, which is in contact with the skin, is fixed with the main body in a point-to-point bonding mode, glue is non-conductive, and the conductivity of the conductive part can be affected after bonding, so that the integral resistance value becomes unstable, and the glue has the problem of service life, is long in service time and is easy to degum; a common conductive part uses conductive silica gel and a conductive metal head, the conductive metal head and the conductive silica gel are not easy to be glued, the surface of a silica gel material needs to be treated, but the treated silica gel is easy to become brittle, and the possibility of breakage or falling of the conductive part is increased; to some miniature electro photoluminescence treatment products, the conductive part volume diminishes, and production or assembly process are difficult to the management and control, and glue when gluing scribbles can be too much or too little for the bonding is insecure.
