FR2881327A1 - Depilation device for removing hairs from e.g. legs, has depilation support with axle on which positive conductor roller, disk and negative conductor roller are aligned to send current to hair roots, and multiclip roller to remove hairs - Google Patents

Abstract

The device has a case on which a depilation support (1) is placed. The support has, at its front in a direction of its displacement, an axle and at its rear a multiclip roller (2). A positive conductor roller (3), an insulating separation disk (5) and a negative conductor contact roller (4) are aligned on the axle for transmitting an electric current to hair roots during passage on hairs, and the roller (2) removes the hairs.

Description

The present invention relates to a device which allows in the same

  time, during an electric depilation, to destroy the hair follicle and tear off the hair.

  Traditional electric epilators typically use a multi-pliers roll that pulls out the bristles exclusively. They do not prevent regrowth because they do not act on the roots.

  The present invention aims to overcome this disadvantage.

  The method according to the invention consists in passing the epilator over the area to be depilated, diffusing an electric current by electrolysis on the hair to reach its papilla and its root, just before tearing it off with the multi-roll. pliers.

  Thanks to this simultaneous process, the hair root is destroyed, the hair is removed and its regrowth is considerably slowed down.

  The device to implement for the realization of said method comprises in fact according to a first feature, a hair removal support with two rollers. This consists of a double conductive roller diffusing an electric current, placed just in front of the multi-gripper roll. Thus, when the user passes the apparatus on the area to be depilated, the double conducting roller which is connected to the internal generator rolls first on the hair and by contact transmits the current. The multi-gripper roll then passes over the pile and pulls it off.

  According to particular embodiments: the conductive roller may comprise two isolated elements: a long element positively connected, for the diffusion of the current and a short element connected in a negative way, for the return of the current.

  - The conductive roller may comprise only the element, positively connected. The current is restored by a metal part negatively connected and fixed on the outer face of the housing, in order to be in contact with the hand.

  In both cases, the resistance of the body is at the same potential as the 3o internal generator and the electrolysis circulates perfectly.

  The accompanying drawings illustrate the invention: FIG. 1 represents, seen from above, the device of the invention and FIG. 2 represents the sectional view.

  3 shows, seen from above, a variant of this device.

  3S With reference to the drawings of Figures 1 and 2, the device comprises an epilation support 1 which is fixed on the housing 7, Figure 4. This support 1 is provided with two rollers aligned in parallel. At the rear is positioned the multi-gripper roll 2 and at the front are positioned on the same axis, the positive conductive roll 3 and the negative feedback current conducting roll 4, 4o separated by an insulating disc 5.

  The support 1 is U-shaped. Figure 6 illustrates the top view, Figure 7 is the front view, and Figure 8 shows the side view.

  Figure 9 shows, in longitudinal section, mounting on the axis 6 of the two conductive rollers 3 and 4 diffusing the electric current and 1f5 disc 5, made of insulating material, which separates them.

  Figure 10 specifies the production of the conductive rollers 3 and 4. Each roll consists of a solid cylinder 10, plastic, covered with a metal tube 11, thin.

  By way of non-limiting example, the rollers will have a diameter of the order of 20 mm and a length of 22 mm for the roll 3 and 8 mm for the roll 4.

  Figure 11 shows, in section, the electrical connection of the positive and negative conductive rolls. Each contact rod 9 is connected to the internal generator 12 and remains in permanent contact with the corresponding roller. Current transmission is by simple friction.

  FIG. 12 represents, in section, the mounting at the rear of the support 1, of the multi-gripper roll 2.

  FIG. 13 represents the block diagram of the mechanical and electronic assembly.

  The advantage of the device is to place first in the direction of movement of the epilator, the double conductive roller, to allow the electrolysis of the hair before tearing.

  According to the variant embodiment illustrated in FIG. 3, the support 1 is provided with the multi-gripper roll 2, always positioned at the rear, but at the front and over the entire width, there is only the positive conductive roller 3.

  In this case, Figure 5 shows that the metal plate 8, externally fixed on the housing 7, ensures the negative feedback contact of the current 2O.
