Definitions

  • the present invention relates to the field of apparatus for the maintenance of the hair system and more particularly for the maintenance of hair.
  • the invention relates in particular to a device for combating parasites coming to be fixed in the hair system such as lice and nits.
  • parasites coming to be fixed in the hair system such as lice and nits.
  • the eradication of other parasites which come to be fixed on the hair, human or animal hair is also conceivable by a device in accordance with the present invention.
  • the object of the present invention is to provide a device for destroying parasites, in particular lice and nits which come to settle on the hair system, by locally providing thermal energy.
  • Another object of the present invention is to provide a device comprising means brought to a temperature sufficient to destroy the parasites fixed in / on the hair system by using neither electrical discharges, nor a projection of steam or hot air. .
  • An additional object of the present invention aims to achieve in a simple and inexpensive manner a device in the form of a comb allowing on the one hand to destroy the parasites coming to be fixed in / on the hair system and on the other hand to carry out operations maintenance of the hair system very simple.
  • a device for eradicating parasites from the hair system comprising a handling body on which is fixed a comb provided with teeth and means for destroying parasites, making it possible to at least locally increase the temperature of the hair system when the teeth of the comb are moved in said hair system, characterized in that the teeth of the comb, penetrating into the hair system, have at least one thermal conductive portion in relation to means generating the thermal energy required to destroy parasites when they come into direct contact with the teeth of the comb.
  • Figure 1 shows a sectional view of the device according to the invention.
  • the latter relates more particularly to personal hygiene devices used to eliminate parasites such as lice or nits in the hair.
  • the device according to the invention comprises a handling body 1 composed of a first part 1a and a second part 1b.
  • the latter are assembled by means of a bore 2 made through said parts 1b, 1a and by an assembly means of the screw type 2a, or any other known means for integrally joining the first part 1a and the second part 1b .
  • the handling body 1 therefore constitutes a gripping member for the device according to the invention.
  • the handling body 1 has a specific configuration in its lower part which is intended to maintain an assembly of teeth forming a comb 9.
  • the device according to the invention comprises a thermal source making it possible to raise the temperature of the teeth so as to heat the hair system in contact with said teeth to a temperature above 60 ° C. Reaching such a temperature is essential for degrading the proteins of possible living or parasitic beings fixed on the hair system.
  • the teeth are spaced from the base of the hair system, which is materialized by the skin of a patient, by a difference h of at least a few tenths of millimeters by means of thermally insulating heels 30, 31 and fixed at least on the ends of at least certain teeth to avoid direct contact between the base of the hair system and the thermally conductive portions of the teeth.
  • the heels 30 and 31 therefore make it possible to avoid burning sensations in the user of the device during the maintenance of the hair system.
  • the thermally conductive portions of the teeth of the comb 9 are crimped in a metal support, which is in thermal relation with the thermal source.
  • the metal support is a metal bar comprising slots or recesses into which the ends of the thermally conductive portions of the teeth are introduced.
  • the teeth are intimately linked with the metal bar.
  • the latter is in thermal contact with the thermal source consisting of at least one heating element of the PTC type, for example supplied by the sector.
  • thermal regulation is ensured by a thermal probe, for example a NTC resistor associated with electronic means.
  • the teeth are designed in a known manner or are advantageously in the form of metal blades 10 shown for example in Figure 3.
  • the blades 10 are crimped into the metal support not shown in the figures using the part upper 12a of said blades 10. The latter are thus heated by thermal conduction.
  • the metal support is fixed, by any known means, to the handling body 1.
  • the material constituting the blades 10 is, for example, hardened brass in this embodiment according to the invention, in order to have good mechanical strength.
  • the blades 10 have a particular shape as shown in FIGS. 1 and 2.
  • Each of the blades 10 has a shoulder 12 on either side which is inserted into a groove 3 formed in the handling body 1 and more particularly in the first part 1a and in the second part 1b. When the latter are assembled, they maintain the assembly of blades 10.
  • the assembly thus formed is in the form of a comb 9 whose teeth are formed by the blades 10.
  • the latter are assembled together by means of a rod 22 passing through all the blades 10.
  • the rod 22 has a thread at each end on which a nut 22a is screwed.
  • the teeth thus formed have a substantially U shape with two vertical branches 10a, 10b fixed by their upper ends in the handling body 1 and a horizontal branch 10c connecting the two vertical branches 10a, 10b so as to position the horizontal branch 10c in look at the base of the hair system when the comb 9 moves in the hair system.
  • the vertical branches 10a and 10b are each crossed by a rod 22.
  • the vertical branches 10a and 10b extend in the same plane for example, and are spaced by a spacing 13.
  • the comb 9 therefore consists of an assembly of teeth in the form of metal blades 10.
  • two successive blades 10 are separated by washers 20 also mounted on the rods 22 so as to space the blades 10 relative to each other.
  • the successive blades 10 thus produced are spaced a distance of less than 2 mm preferably.
  • Such a spacing is advantageous in particular for the treatment and maintenance of the hair and in particular for the release of parasites attached to the hair.
  • such a spacing of less than 2 mm requires the parasites to come into contact with at least one of the blades 10 forming the comb 9, when the said parasites are in a part of the hair system crossed by the comb 9. The parasites are thus killed by means of a significant heating.
  • the thickness of the blades 10 is of the order of 0.4 mm and the width of said blades 10 is preferably between 15 and 20 mm, including the vertical branches 10a, 10b and the spacing 13. Such dimensions are advantageous to obtain sufficient thermal capacity to heat the hair to a temperature above 60 ° C when the blades 10 pass through the hair.
  • the free height of the blades 10 and more particularly of the vertical branches 10a, 10b extending for example along the axis x-x ', is between 15 and 20 mm. Such a free height, preferably measured without embedding the blades 10 in the handling body 1, allows said blades 10 to reach the scalp near which the nits are housed.
  • the heels 30, 31 are fixed to the ends of the horizontal branches 10c of the blades 10 for example with rivets 32 as shown in Figure 1.
  • the heels 30 and 31 are overmolded on the ends of the horizontal branches 10c and are made of plastic material resistant to high temperatures.
  • the heels 30 and 31 may also, according to another alternative embodiment of the device according to the invention, extend over the entire part of the horizontal branch 10c which is facing the base of the hair system, so as to avoid direct contact between the horizontal branch 10c and the base of the hair system or more precisely the skin of the user, while only slightly covering the blades 10 so as not to hinder contact between parasites and blades 10.
  • the comb 9 is made up of an assembly of successive blades 10, said assembly making it possible to produce a leading edge of the hair system with blades 10 alternately in front and in retreat to be more easily introduced into the hair system. .
  • Such a configuration is obtained for example by a more or less significant flaring of the successive blades 10 and by heels 30 and 31 of different size.
  • Large heels 30 have a bent shape with a horizontal part, coming to bear on the scalp, while small heels 31 fixed by any means on a blade 10 following have any parallelepiped shape and are set back from the large heels 30 The small heels 31 and the large heels 30 also come to bear on the user's scalp.
  • the successive blades 10 alternately have a large flare 14 and a small flare 15 so as to accentuate the ease of penetration of the comb 9 thus formed in the hair system.
  • the blades 10 have an asymmetrical configuration with a large flare 14 on one of the vertical branches 10a and a small flare 15 on the vertical branch 10b.
  • the assembly of the asymmetrical blades 10 is therefore done in a two-sided manner, in order to produce a comb 9 with two leading edges each having, alternately, a large flare 14 and a small flare 15, on which are respectively fixed a large heel 30 and a small heel 31.
  • the entry into the hair of the comb 9 is therefore progressive by the presence of a succession of edges of blades 10 alternately in front and in withdrawal.
  • the large heels 30 and the small heels 31 are overmolded on the acute angles formed by the angles between the vertical branches 10a, 10b and the horizontal branches 10c.
  • the blades 10 are for example made of stainless steel.
  • the thermal source is produced by the blades 10, which are crossed by an electric current to cause heating of said blades 10.
  • the latter are all connected in series so that that they are all crossed by an electric current of the order of 8 amperes under a voltage of 3 volts for example.
  • the serial connection of the successive blades 10 is obtained by means of the washers 20 separating each blade 10.
  • the washers 20 are alternately electrically insulating and electrically conductive, so as to create a path for the electric current, passing for example from the branch vertical 10a to the vertical branch 10b through the horizontal branch 10c.
  • the spacing 13 contributes to materializing the path of the electric current in each blade 10.
  • the electric current then passes to the next blade 10 via the electrically conductive washer 20 and travels in the opposite direction.
  • the latter allows the electric current to pass from the vertical branch 10b to the branch 10a via the horizontal branch 10c in this adjacent blade 10. It is the same for the passage of current in all the adjacent blades carrying out the assembly of teeth of the comb 9.
  • the presence of alternately insulating and electrically conducting washers 20 makes it possible to create a path for the electric current passing through all of the blades 10, which are thus electrically connected in series.
  • Each vertical branch 10b or 10a is separated from the next vertical branch 10b or 10a alternately by an electrically insulating washer 20 and an electrically conductive washer 20.
  • the horizontal branch 10c has a cross section smaller than the cross section of the vertical branches 10a, 10b so as to constitute the hottest zone of the blades 10 when said blades 10 are crossed by an electric current. Indeed, it is the horizontal branches 10c which come closest to the scalp when the comb 9, consisting of the blades 10, is introduced into the hair system.
  • the small section of the horizontal branch 10c makes it possible to produce heating by a large Joule effect.
  • the blades 10 therefore produce the heating means themselves without using an additional or separate heating element.
  • the small section of the horizontal branch 10c has a surface of the order of 20 mm and preferably between 10 and 30 mm.
  • the rods 22 shown in FIG. 1 passing through the vertical branches 10a and 10b are advantageously electrically isolated, by any known means, from each vertical branch 10a or 10b which they pass through, so as not to alter the series electrical connection of all the blades 10.
  • the rods 22 are for example surrounded by an electrical insulating sheath and resistant to high temperatures, or are not simply in contact with the vertical branches 10a and 10b, having an adequate diameter.
  • the rods 22 are replaced by any other known mechanical means allowing a compact assembly of the blades 10 and spacing washers 20, which are alternately electrical insulators and electrical conductors.
  • the assembly of the blades 10 is associated with a thermal sensor 33 disposed in the vicinity of the upper part of said assembly and preferably above the rod 22 and in the vicinity of the handling body 1.
  • the dimensions of the blades 10, easily determined by experimentation therefore make it possible to produce a comb 9 consisting of teeth in the form of blades 10 so that the most hot, in this case the horizontal branches 10c, have a temperature below 140 ° C.
  • Such a temperature limit is essential in order not to damage the hair or the hair system in general and remains very sufficient for the destruction of parasites.
  • the hottest areas of the blades 10 are brought to a relatively high temperature approaching 140 ° C. which allows a significant temperature drop when the device according to the invention passes through the hair while avoiding a drop in temperature of the blades 10 which come into contact with the hair below a temperature of 60 ° C.
  • the thermal sensor 33 preferably consists of an electronic thermostat and compensates for a heat expenditure by controlling the electric current circulating in the teeth and more particularly in the blades 10 of the comb 9.
  • the heat expenditure of the blades 10 is essentially due to the displacement of said blades 10 in a hair at room temperature.
  • the electronic thermostat comprises for example a temperature sensor of the NTC resistance type associated with known electronic means not shown in the figures.
  • the latter comprises conventional heating means of the type electric heating resistors or shielded heating elements which make it possible to heat the teeth or the blades 10 by thermal conduction only.
  • Optimal operating temperatures can also be reached by using heating elements with a power appropriate to the size and configuration of the teeth used.
  • the device according to the invention therefore makes it possible to eradicate the parasites coming to be fixed in / on the hair system by a process consisting in using a comb 9, in moving the teeth of the hair comb 9 in the hair system and in using said teeth of the hair care comb 9 to provide thermal energy at least locally to the hair system.
  • the method according to the invention also consists in supplying the hair system with thermal energy to heat the hair system at least locally to a temperature above 60 ° C.
  • the method consists in heating at least a portion of the teeth of the comb 9 by the Joule effect.
  • the variant embodiment of the device according to the invention comprises an assembly of blades 10 and metal spacers 20a.
  • the assembly consists alternately of a blade 10 and a metal spacer 20a.
  • the latter advantageously replaces a washer 20 used in other alternative embodiments of the device according to the invention.
  • the metal spacers 20a and the blades 10 therefore have a bore 34 of the same diameter so as to produce inside the assembly obtained, an internal cylindrical volume in which can be accommodated a ceramic support and heating wires to produce the heat source of the device. Any other heating means can be arranged inside this assembly without departing from the scope of the present invention.
  • the metal spacers have a substantially rectangular shape and are fixed to the blades 10 and to the parts 1a, 1b of the frame using four tie rods 23 disposed around the bore 34 and passing through all of the blades 10 and metal spacers 20a .
  • the metal spacers 20a intimately linked to the upper ends of the blades 10 thus produce a metal support carrying out the thermal transfer from the heat source to the blades 10.
  • the tie rods 23 are advantageously fixed to the parts 1a and 1b of the frame.
  • the thermal sensor 33 is advantageously placed in the handling body of the device and at above the assembly formed by the blades 10 and the metal spacers 20a.
  • the blades 10 have in this embodiment, substantially the same rectangular shape in their upper part, as the metal spacers 20a. This allows in particular to promote heat transfer in the assembly thus formed.
  • the operation of the device according to the invention is as follows. After the blades 10 have stabilized in temperature, the user grasps the device and introduces it via the heels 30, 31 into the human or animal hair system.
  • the displacement of the comb 9 formed by the assembly of the blades 10 makes it possible to obtain at least locally a temperature above 60 ° C.
  • the means for destroying the parasites therefore comprise in combination a comb 9 and a heat source.
  • An advantage of the device according to the invention lies in the fact that it is capable of destroying lice and nits, and thereby hampering the reproduction cycle of said parasites. The period during which the device according to the invention is used can therefore be reduced.
