Description

[Detailed Description of the Invention] The present invention relates to a permanent hair removal device that incorporates a mechanism that can variably control the output state in order to improve the hair removal effect.

The device targeted by the present invention performs permanent hair removal based on the principle of electrolysis or dielectric heating by applying a DC voltage or high frequency voltage to the area to be removed. In the case of electrolysis, when a DC voltage is applied so that the electrode held in the palm is the positive electrode and the electrode inserted into the hair follicle is the negative electrode, electrolysis occurs due to the moisture present in the hair follicle. is generated and becomes alkaline, causing hair removal.

To remove hair using high frequency waves, high frequency waves are applied from the same electrodes as described above, and the moisture within the hair follicle is heated by dielectric heating to permanently remove hair.

Furthermore, if necessary, the above-mentioned methods may be combined to remove hair.

Such an epilator must perform reliable hair removal while maintaining safety. However, the target for hair removal depends on age, gender, etc.
It is not easy to set the optimum conditions since hair conditions, skin conditions, etc. vary widely. Conventionally, operations have relied on the user's intuition, but this has been extremely unsatisfactory as over-processing or under-processing tends to occur. Furthermore, since this is dealt with only by adjusting the intensity of the electrical output, it is difficult to make sufficient adjustments for sensitive or weak skin.

An object of the present invention is to provide a permanent hair removal device that can control the electrical output pattern based on inputs that are determined depending on the area to be removed.

The object of the present invention is achieved by the permanent hair removal device described in the claims of the utility model registration.

The permanent hair removal device according to the present invention enables safe and reliable hair removal in accordance with the condition of the skin to be removed, and does not require special skill. Therefore,
Overtreatment or undertreatment of hair removal is avoided, and permanent hair removal is performed with fewer steps.

The present invention will be disclosed below with reference to the accompanying drawings.

According to FIG. 1, a permanent hair removal device 10 indicated by a broken line frame includes a direct current generating section 11 and a high frequency generating section 12. The output of both of these generators is switch SW ₁
and SW ₂ to the terminal 13, and further reaches the needle electrode 14 via a suitable cord. A common electrode 16 connected to a terminal 15 grounded to the housing is provided for the needle electrode, and a DC output or a high frequency output is applied between the two electrodes, either singly or simultaneously.

The epilator 10 includes a central processing unit CPU 17 that controls each generator 11 and 12, and a display 18 that displays the output of the CPU 17 if necessary.

The CPU 17 is composed of an input processing section 19 and a calculation section 20, which receive various data determined from the input terminal _T1 depending on the area to be hair removed. this
The output of the CPU 17 is applied to storage sections 21 and 22, and the output states of the respective front generation sections 11 and 12 are controlled by controllers 23 and 24 which receive the outputs from the storage sections.

The input data from the input terminal _T1 is an electrical signal obtained from, for example, the water content in the skin, especially in the hair follicle, the softness and hardness of the hair, the condition of the skin, etc., and can be detected and measured by various known means. Or it can be a set value.

If a display 18 is provided, control results obtained from each of the above-mentioned data are displayed.

The output waveforms controlled according to such data can be as shown in FIGS. 2a to 2e. It goes without saying that the waveform, connection time, rest time, zero potential, etc. can be combined as appropriate.

FIG. 2a shows a state in which electrical output is continuously applied when the skin is hairy and insensitive. Figure 2c
indicates a short-duration pulse. Figure 2 d, e
is an appropriate combination of these, and is appropriately selected depending on the conditions.

In the permanent hair removal device according to the present invention, hair removal is performed by grasping the common electrode 16 shown in FIG. 1 with, for example, the palm of the hand, inserting the needle electrode 14 into the hair follicle, and applying the above-mentioned output.

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