Description

[Detailed Description of the Invention] The present invention relates to a permanent hair removal device that includes a built-in moisture content measuring mechanism on the human body side, which has a significant effect on hair removal.

The device targeted in the present invention is one that electrically permanently removes hair, and conventionally used methods include an electrolysis method using a DC power source, a high frequency method, and a method that uses these methods in common. In the type that uses electrolysis, when a DC voltage is applied so that the electrode held on the skin, for example in the palm of the hand, is the positive electrode, and the electrode inserted into the hair follicle is the negative electrode, the electrolysis occurs inside the hair follicle. Moisture causes electrolysis, which becomes alkaline, which attacks the inside of the hair follicle, resulting in permanent hair removal.

In the type that uses high frequency, high frequency is applied from the same electrodes as mentioned above, and the moisture in the hair follicle is heated by dielectric heating, thereby performing permanent hair removal.

Furthermore, in a type that uses both devices, permanent hair removal is achieved by using a device in which the above-mentioned devices are combined, resulting in a synergistic effect.

In any case, in permanent electrical hair removal, the moisture content of the skin to be removed, especially the hair follicle, has a significant effect on the hair removal effect. However, it is impossible to judge the moisture content in each individual skin, especially in the hair follicle, by sight or touch, and conventional operations have relied on the intuition of the device user. It is impossible to accurately grasp the amount of moisture in the hair follicle, which varies not only by age and gender, but also by location, and to perform hair removal that is appropriate for this, and the problem of over-treatment or under-treatment continues. Nakatsuta.

The purpose of the present invention is to provide a permanent hair removal device that has a built-in mechanism that measures the moisture content of each hair follicle and skin to be removed, displays the measured value, and controls the hair removal process according to this measured value. It is to be.

This object is achieved by a permanent hair removal device having the structure described in the claims of the utility model registration.

According to the permanent hair removal device of the present invention, moisture in the hair follicle and skin is detected and measured prior to the hair removal operation, and appropriate hair removal treatment is performed according to the measured values. That is, since the hair removal process is performed without involving the user's intuition, reliable hair removal is possible, and the problem of over-treatment or under-treatment can be solved. Therefore, safe hair removal treatment is possible without requiring special techniques.

Hereinafter, the present invention will be disclosed with reference to the accompanying drawings.

FIG. 1 shows a block diagram of a permanent hair removal device according to the present invention, and shows the configuration of the device with the power supply section omitted. The permanent hair removal device indicated by the broken line 10 includes a changeover switch 11, a detector 12, a central processing unit CPU13, a high frequency generator 14, a DC generator 15, and each generator 14, depending on the output of the CPU 13.
Storage units 19 and 21 and control unit 2 that control 15
0, 22 and a display 16 for displaying measured values if necessary. The CPU 13 includes an input processing section 17 and an arithmetic section 18. Furthermore, the permanent hair removal device 10 includes input/output terminals T ₀ , T ₁ , and T ₂ .

A gripping rod 23 serving as a common electrode for moisture measurement and hair removal treatment is connected to the terminal T ₀ . terminal
An electrode 24 for measuring skin moisture and for pre- and post-hair removal treatment is connected to _T1 . A needle electrode 25 for measuring moisture in the hair follicle and for hair removal is connected to the terminal _T2 . Each electrode 23, 24, 25 contacts or is inserted into a human body 26 to be subjected to hair removal treatment.

The operation of the permanent hair removal device according to the present invention will be explained below. When changeover switch 11 is set to contact 1,
It becomes possible to measure skin moisture and perform pre- and post-hair removal treatments, and when aligned with contact point 2, it becomes possible to measure moisture within the hair follicle. The hair removal process is performed in a state that matches the contact point 3.

When measuring skin moisture, select switch 1.
1 to contact point 1, hold the grip stick 23 in the palm of your hand, and bring the electrode 24 into contact with the skin to be measured. When measurement is performed in such a state, the detector 12 detects inputs from the gripping rod 23 and the electrodes 24, and applies the detected output to the input processing section 17 in the CPU 13.
The detected value is processed by the calculation unit 18 and displayed on the display 16 if necessary.

When measuring the moisture in the hair follicle, the switch 11 is set to the contact point 2, the gripping stick 23 is held in the palm of the hand, and the needle electrode 25 is inserted into the hair follicle to be removed. When measuring in such a state, the detector 12
The electrical resistance between the nigiri rod 23 and the needle electrode 25 is detected, processed in the same manner as described above, and displayed on the display 16.

In the hair removal process, the optimum voltage and application time are set based on the above-mentioned moisture measurement results. These controls are carried out by the processing unit 18 in the CPU 13.
The first and second storage units 19
Each control section 20 and 22 performs a control operation based on the data stored in and 21. Each control unit 2
The outputs of 0 and 22 control the DC generator 14 and the high frequency generator 15, respectively. As a result, hair removal treatment is performed under conditions that are optimal for the state of moisture within the hair follicle and on the skin.

The treatment before (after) hair removal is performed by switching the additional switch 27 to the contact B side, setting the changeover switch 11 to contact 3, and applying a weak voltage between the nigiri rod 23 and the electrode 24. By performing the pretreatment, the pores are opened, making it easier to insert the hair removal needle electrode, and ensuring hair removal. In post-hair removal treatment, the polarity between the electrodes is reversed to restore the pores to their original state and neutralize the entire area.

After the pretreatment, the contact of the additional switch 27 is set to the A side while the changeover switch 11 remains at contact 3. The tip of the needle electrode 25 is inserted into the pore, and hair removal treatment is performed according to the time and voltage set based on the previous measurement, and the combination of direct current and high frequency.
These set values are determined based on the moisture measurement value taken just before, and the hair removal process is performed under conditions that are optimal for age, sex, hair follicle, skin condition, etc. Therefore, since the user does not rely on his/her intuition, it is possible to perform an accurate hair removal treatment without requiring a particularly high level of skill.

Although the invention has been disclosed based on illustrative embodiments, it will be obvious that many modifications and variations may be made within the scope of the invention.
