Definitions

  • the present invention relates to an apparatus for treating hair fibers.
  • contact surface we mean a hair treatment surface, preferably a straightening surface, for example constituted by an advantageously heated straightening plate as will be detailed later.
  • Each treatment surface is intended to be in contact with at least one strand of hair when treating the hair.
  • the confinement, at least partial, obtained according to the invention makes it possible to locally accumulate steam, advantageously outside the contact surfaces, in the volume located between said at least one steam outlet and the confinement structure, this which may lead to a reduction in steam flow required for hair treatment. It is possible, due to the reduction in the quantity of steam necessary for the treatment, to extend the autonomy of the device and to reduce the quantity of residual humidity of the hair when leaving the device.
  • the containment structure can contribute to a better distribution of the steam longitudinally, between the steam outlets. The lock of hair can thus be treated in a more homogeneous in the transverse direction.
  • the partitioning created by the confinement structure makes it possible to apply most of the steam only locally, during the passage of the lock of hair in the zone located between said at least one steam outlet and the throat, zone which can thus be qualified as a steam application zone.
  • the strand of hair is then detangled first during the straightening process and the hair fibers are well ordered before undergoing the steam treatment, which improves the effectiveness of the latter. Then, the strand of hair passes between the contact surfaces which are kept closed in order to apply pressure on the latter and complete the straightening process.
  • the device is perfectly ambidextrous.
  • the groove may have a width, measured perpendicular to the longitudinal axis of the contact surfaces, preferably plates, and parallel to the heating surfaces in close configuration of the arms, of between 1 and 20 mm, preferably between 2 and 12 mm and advantageously substantially equal to 4 mm.
  • the groove may have a depth of between 1 mm and 15 mm, preferably between 2 and 5 mm, and advantageously substantially equal to 2.5 mm.
  • the throat does not have its own heating means, such as an electrical resistance. The temperature of the surface at the bottom of the throat preferably comes almost exclusively from the heating of this surface caused by the projection of steam.
  • the edges of the groove do not preferably come into contact with a surface of the opposite arm carrying said at least one steam outlet.
  • the steam outlet(s) are preferably supplied with steam by a vaporization chamber which is itself supplied with water by a pump.
  • the nozzle(s) are of conical shape with a circular section, and the section of the nozzles widens towards the outlet of the nozzles.
  • the steam is preferably water vapor, in particular without additives.
  • the device may not include a reservoir for a cosmetic composition, nor a cosmetic composition applicator.
  • the device 1 is autonomous, with integrated water tank 2. Only part of the power cord 3 is visible on the figures 1 and 2 .
  • the arms 4 and 5 are articulated together by means of a pivot connection 6 so as to form a clamp.
  • the housings of the arms 4 and 5 include respective shells 17 and 18, which house different constituent elements of the device.
  • the arms 4 and 5 are movable in the close configuration along the lock of hair to be treated and comprise respective proximal parts 4a and 5a which can be concomitantly grasped with one hand to manipulate the device 1.
  • the device 1 comprises at least one steam outlet 20, in this case several outlets, carried by the arm 4 at a distance from the plate 10, to expose the hair engaged between the arms 4 and 5 to steam when they are found in this steam application zone.
  • the arm 4 further comprises a comb 30 which has, in the example illustrated, a single row of teeth 31, visible on the figures 2 And 7 notably.
  • the comb may include rigid teeth and/or flexible bristles such as tufts of silk bristles.
  • Each steam outlet 20 comprises a channel 26 extending along an axis figures 4A And 4C , surmounted by a nozzle 27, the axis X being that of the steam outlet.
  • Each nozzle 27 has a shape flared outwards. This makes it possible to distribute the steam evenly throughout the containment zone and to continuously renew the steam which escapes from the containment zone, in particular from the front and/or the rear of the device.
  • the groove 25 is centered on the axis X, that is to say that in cross section, the axis of the groove coincides with the axis X of the steam outlet.
  • the bottom of the groove is at a distance d from the upper end 28 of the nozzles 27 equal to approximately 8.5 mm in this example, when the arms 4 and 5 are in a close position.
  • the throat 25 does not have its own heating system.
  • each nozzle 27 has for example a height h of 2.8 mm and a maximum width l , at its upper end, of 3.4 mm.
  • Each channel 26 has for example a height h' of 4.8 mm and a width l ', corresponding to an internal diameter of 1.6 mm.
  • the lower part of the arm 4 houses the vaporization chamber which allows the creation of steam which is then projected through the outlets 20 passing through the channels 26 and nozzles 27.
  • Such a vaporization chamber may include a heating device consisting for example of a thermistor with a positive temperature coefficient, called PTC, and a device for measuring the temperature of the heating device consisting for example of a thermistor with a negative temperature coefficient, called CTN.
  • PTC positive temperature coefficient
  • CTN negative temperature coefficient
  • the total steam flow delivered by all steam outlets can be between 0.5 g/min and 0.8 g/min.
  • the steam outlets 20 are supplied with steam by a vaporization chamber which can be supplied by means of a pump and in particular a peristaltic pump, itself connected to the tank 2, these elements being preferably located in the same arm 4.
  • the arm 5 comprises at least a first part 140 for supporting the plate 11 and at least one second part 141 distinct from the first and separated from it.
  • the device 1 further comprises a sealing element 150, elastically deformable, comprising a proximal portion 151 extending at least partially around the plate 11 between the latter and the first part 140 and a distal portion 152 extending at contact of the second part 141, the proximal portions 151 and distal 152 being connected by an intermediate portion 153, flexible, extending between the first and second parts 140 and 141.
  • the proximal portion 151 extends over the entire circumference of the plate 11.
  • the distal portion 152 is, for its part, pinched between the second part 141 and a third part 142 of the arm 5, formed in this example by the shell 18.
  • the intermediate portion 153 has at least one bend in cross section.
  • the intermediate portion 153 is curved concave towards the opposite arm 4, with a U-shaped bottom in cross section.
  • the intermediate portion 153 then has a shape similar to a bellows, such as an accordion bellows which gives the intermediate portion 153 of the sealing element 150 a great flexibility, advantageously to be able to follow the movement of the plate 11 as described below while guaranteeing sealing around the plate 11.
  • the plate 11 has an outline of generally rectangular shape with four sides.
  • the intermediate portion 153 and the distal portion 152 extend around three of the four sides of the plate 11 only.
  • the intermediate portion 153 and the distal portion 152 are absent from the side 16 of the plate 11 furthest from said at least one steam outlet 20.
  • the sealing element 150 only comprises the proximal part 151 of the side 16 of the plate 11 which is opposite the steam outlet 20.
  • the proximal part 151 is extended by the part intermediate 153 of the sealing element 150, as visible in particular on the Figure 4A Or 4C .
  • the fact of limiting the sealing element 150 forming a seal to only the proximal part 151 of the side 16 of the plate makes it possible to reduce the width of the device 1 without significantly harming the sealing.
  • the sealing element 150 as in particular visible in isolation on the Figure 12 , has a non-symmetrical shape with respect to a median plane crossing the plate 11 parallel to the longitudinal axis Y of the device 1 and perpendicular to a heating surface 12 of the plate 11 facing the plate 10.
  • the proximal portion 151 of the sealing element 150 is mounted over the entire periphery of the plate 11, being interposed between the plate 11 and the first plate support part 140.
  • the peripheral edge of the plate 11 is isolated from the first plate support part 140 by the sealing element 150, which makes it possible to make the assembly watertight.
  • the device 1 may also include an electronic card, not shown, configured to manage the electrical power supply to the resistive heating elements in order to control the operating temperature.
  • This electronic card can be arranged inside one of the two arms 4 or 5, for example in the proximal part 4a of the arm 4, and have a user interface.
  • the device 1 may further comprise a magnetic sensor, not illustrated, of the ILS flexible reed switch type, which makes it possible to detect the close configuration of the arms 4 and 5, in which the surfaces 12 and 13 are substantially against each other. 'other to pinch the section of hair to be treated.
  • the flexible reed switch is replaced by a magneto-resistive sensor MRS, or by any other means of detection.
  • the steam outlets 20 are organized in the example considered in a row, the latter being parallel to the longitudinal axis Y as well as to a lateral edge 37 of the heating plate 10 and to the row of teeth 31 of the comb 30, as visible on the Figure 7 .
  • the row of steam outlets is arranged between the comb 30 and the lateral edge 37 of the plate 10.
  • the distance f between two adjacent nozzles 27, measured between the axes of these as visible on the figure 5 is for example equal to 9.7 mm.
  • each steam outlet 20 is set back from the plane (Y, Z) defined by the surface 13, the distance e between it and the plane (Y, Z) being equal for example at 4.6mm.
  • the upper end 28 of each steam outlet 20 is also set back relative to the plane T connecting the end M of the surface 13 and the base N of the teeth of the comb, as visible on the Figure 9 .
  • the confinement structure 21 comprises, in addition to the groove 25, a covering 40 for the comb, separated from the groove 25 by a rib 41. The latter extends parallel to the longitudinal axis Y.
  • the confinement structure 21 is constituted by a single molded part of thermoplastic material, in the example illustrated. We do not depart from the scope of the invention when the confinement structure 21 is made from several parts assembled together.
  • the containment structure 21 is located mainly set back from a plane W illustrated in dotted lines on the Figure 7 , connecting the edge O of the contact zone between the plates 10 and 11 in close configuration of the arms 4 and 5, and the top of the comb 31 corresponding to the straight line F joining the ends of the comb teeth.
  • Rib 41 in this example, protrudes slightly under plane W.
  • the confinement structure 21 can be fixed on the associated arm in various ways.

In the example illustrated, the groove 25 does not have symmetrical edges with respect to a plane parallel to the axis X.
  • the cover 40 only covers in this example, in a close configuration of the arms, a part of the interior side 32 of the teeth 31 of the comb 30, that is to say that facing the plate 11.
  • the covering 40 of the comb 30 covers part of the interior 32 and exterior 33 sides of the teeth 31.
  • the covering 40 may include walls 44 and 45 substantially parallel respectively to the sides 32 and 33 of the teeth 31, at a distance from those -this and offset upwards along the axis
  • the confinement provided by the covering 40 does not prevent the steam from escaping by passing between the teeth 31 of the comb 30 and through the space above the upper end of the teeth 31 under the covering 40.
  • the latter can nevertheless behave with respect to the escape of the steam as an additional obstacle which contributes to the confinement of the latter upstream of the plates 10 and 11.
