Abstract
The electrolytic depilation device works by electrical contact with the skin of an individual whose hair is to be treated by electrolysis. It comprises a case containing an electrical power supply source, an electronic control circuit connected to the electrical power supply source for supplying a first electrode and a second electrode of different polarity. The electrodes are located at a distance from one another to apply a current that initiates electrolysis at the level of the hairs to be treated. At least the first electrode is elongated and located on one of the ends of the case so as to be applied against the skin over its entire length. The electrode has a shape that is convex in cross section.
Description
- This invention relates to an electrolytic device for depilation by electrical contact with the skin of an individual whose hair is to be treated by electrolysis.
- In depilation devices of this type, a continuous current supplied to the entry of a hair follicle is used to reach the papilla joined to the root of the hair and to consequently chemically destroy the papilla by galvanic electrolysis. The liquid contained in the tissue then constitutes an electrolyte during this procedure. Thanks to this electrolysis the root of the hair is destroyed and its regrowth is greatly delayed.
- Electrolytic depilation devices are known in which several needles are used to implement depilation by electrolysis. These needles must be applied to the vicinity of the papillae of the hairs to be treated. The needles comprise first electrodes inserted into the skin of the individual in the vicinity of the respective papilla, whereas a second electrode is placed on the skin for circulation of current.
- One disadvantage of these depilation devices it that it is difficult to distribute the current equally among all the needles. One solution to this problem is proposed in U.S. Pat. No. 4,155,363, but the device described there is relatively complicated and difficult to use.
- Likewise tweezer electrolysis depilation devices are known that comprise a needle that forms the electrode which must be inserted into the hair follicle. Such a device is described in U.S. Pat. No. 4,784,136, but the double treatment it offers is complex and it is difficult to handle this device effectively and quickly.
- Another tweezer electrolysis depilation device comprising a needle that forms the electrode is known from GB 2296867 which proposes facilitating current return by making part of the handle of the device electrically conductive.
- Again, another electrolytic depilation device is described in U.S. Pat. No. 3,994,300. This device comprises several needles that form the electrodes and an electrically conductive grating which is located in front of the needles to comprise a ground surface as it is being applied against the skin of the individual to be treated. This device operates by electrical discharges intended to destroy the hair follicles.
- Moreover a device for depilation by electrolysis is known that comprises a case containing an electrical power supply source and an electronic control circuit. This case can be electrically connected to a stylus that forms the electrode for treatment of facial hair, and to patches that comprise electrodes of varied shapes adapted to different parts of the human body. However, the use of a stylus is tedious and the patches must be applied carefully relative to one another in order to be effective.
- In light of this prior art and disadvantages linked to the aforementioned known devices, the object of the invention is to propose a simple electrolytic depilation device that is effective and extremely easy to handle.
- The object of the invention is an electrolytic device for depilation by electrical contact with the skin of an individual whose hair is to be treated by electrolysis, comprising a case containing an electrical power supply source, an electronic control circuit connected to said electrical supply source for supplying a first electrode and a second electrode of different polarity, located at a distance from one another to apply a current that initiates electrolysis at the level of the hairs to be treated.
- The electrolytic depilation device according to the invention is characterized in that at least said first electrode is elongated and located on one of the ends of said case to be applied against the skin over its entire length.
- According to other characteristics of the invention:
-
- said first electrode has a shape which is convex in cross section;
- said convex shape is essentially cylindrical;
- said second electrode comprises a metal plate that is fastened on the outer surface of said case and that is able to come into contact with a hand of a user;
- said second electrode has a shape similar to that of the first electrode and extends parallel to it on said end of said case;
- said second electrode has essentially the same length as that of said first electrode and said second electrode has a width less than that of said first electrode;
- at least said first electrode comprises a metal sheet connected to a support fastened to said end of said case, said first electrode exactly following the shape of a convex part in a cross section of said support;
- said first and second electrodes are connected to said support and said support comprises a spacer element extending between said electrodes so as to define an insulating gap between the electrodes;
- said first electrode is an electrically positive electrode placed in front of said second electrode in the direction of movement of the device on the skin;
- said electronic control circuit comprises a processor containing several stored programs allowing differentiated treatments;
- said electrical supply source comprises at least one battery integrated into the device.
- Other characteristics and advantages of the invention will become apparent from the following description of two nonlimiting embodiments of the invention.

second electrodes FIGS. 1 to 4 are connected to an essentiallyrectangular support 10 fastened to the end of thecase 2 using two opposingstraight grooves 10 a provided on the sides of thesupport 10 which accommodate ribs forming aslide 3 a of complementary shape, which ribs are provided on the inside surface of the half-shell 3 of thecase 2. - The first and
second electrodes support 10, preferably essentially cylindrical. These metal sheets are shown inFIG. 8 , before their forming on the support. - Each metal sheet that forms an electrode is provided on one of its corners with a
projection 11 that forms a contact blade linked to an electrical connection (not shown) within thecase 2. - The
support 10 comprises aseparate spacer element 12 extending between the first andsecond electrodes - The
spacer element 12 is dimensioned to be used also as a means of tightening the sheets forming theelectrodes support 10. - The
first electrode 7′ in the second embodiment shown inFIGS. 5 and 6 is also comprised of such a thin metal sheet. - The thin metal sheets comprising the
electrodes support 10 usingpins 13 provided on the periphery of the support. Thesepins 13 are aligned withholes 14 provided in the metal sheets (seeFIG. 8 ). - Another means of fastening the metal sheets consists in inserting them into the gap that has not yet been filled by the
separate spacer element 12, joining the two ends of each sheet by making them overlap one another, and fastening the ends together with screws against the back surface of thesupport 10. - The supply of electric current from the
power supply source 5 is controlled by a start-stop push button 15 located on the front surface of thedepilation device 1. - The
electronic control circuit 6 of thedepilation device 1 comprises preferably aprocessor 16 containing several stored programs allowing differentiated treatments for the hair on the face, the armpits and the legs. - Advantageously the start-
