Definitions
- the present invention relates to a hair treatment brush and the corresponding hair treatment process.
- Patent application DEI 9822718 mentions a comb whose teeth may be perforated in order to emit steam which comes into contact with the hair.
- the brush has no steam outlet nozzles, and the teeth are heated by a heating resistor without steam being applied.
- Such a brush with perforated teeth heated by steam may prove relatively difficult to manufacture and tends to limit the temperature imparted to the hair. It may also result in uneven treatment due to steam being over-concentrated locally in certain parts of the hair.
- Patent application KR20030085159A describes a brush comprising a plurality of teeth heated by a heating resistor in the base and having steam outlets between the teeth.
- the steam outlets and the teeth are distributed over the entire surface of the brush.
- Such a brush therefore does not allow steam to be applied to a limited part of the hair and the action of the steam to be dissociated from the action of the dry heat.
- the present invention meets this need with the aid of a hair treatment brush, in particular for straightening, comprising:
- the brush being configured to emit the steam through the steam outlet at a speed of between 0.007 m/s and 15 m/s, preferably between 0.01 m/s and 3 m/s, and more preferably between 0.1 m/s and 1 m/s.
- the term “brush” should be understood to mean a hair treatment device constituted by a single arm carrying a plurality of teeth between which hairs are received when the brush passes through the hair.
- the brush may comprise a single row of teeth or preferably comprise a plurality of rows of teeth.
- teeth should be understood to mean elements protruding from the brush between which hairs are received when the brush passes through the hair.
- the teeth may have any shape.
- Such a brush allows the hair to be treated effectively by brushing the hair and applying steam with the brush in a single movement.
- the specific speed range of the steam allows the steam to thoroughly penetrate into the hair during the treatment, which improves the treatment in particular in the case of a thick lock of hair, while limiting the risk of discomfort, in particular for the scalp, which could result if the speed of the steam is too high.
- the brush has an elongate shape along a main axis.
- the brush has a different, non-elongate shape.
- the brush comprises a handle and a head.
- the handle makes the brush easier to hold and allows additional elements to be added to the brush, in particular a user interface, a water or cosmetic product reservoir and/or one or more sensors.
- the head of the brush may have any cross-sectional shape.
- the head of the brush has a substantially polygonal cross-section, in particular substantially rectangular or substantially square, substantially oval, or substantially circular.
- the brush comprises a treatment surface, the teeth extending from the treatment surface.
- this treatment surface is planar or bulges towards the outside.
- this treatment surface has a substantially polygonal outline, in particular rectangular or square, circular or oval.
- the teeth may extend in at least one row of teeth, and preferably two rows of teeth, each preferably extending parallel to the main axis of the brush.
- the brush is substantially rectangular and the teeth extend in several rows of teeth, each extending along the main axis of the brush in the case of a brush having a treatment surface with a substantially rectangular outline.
- the row or rows of teeth each comprise at least 3 teeth, preferably between 10 and 40 teeth, and more preferably between 15 and 40 teeth.
- the brush comprises means for heating the teeth for heating at least some of the plurality of teeth, in particular at least two of the teeth, and preferably at least one or more rows of teeth.
- Combining the heating of the teeth and the application of steam helps improve the treatment of the hair. In particular, it allows a higher temperature to be maintained in the steam application spaces, in particular the spaces between the teeth when the steam is projected into these spaces. It also allows the hair to be heated with dry heat before or after the application of steam, which improves the steam treatment of the hair.
- the heating means comprise at least one heating element in the body of the brush for heating the teeth by heat conduction; as a variant, the brush comprises a heating element in each of the heated teeth, in particular forming the core of the corresponding tooth.
- the means for heating the teeth of the heated combing area may comprise at least one active element heating the tooth extending at least partially under the treatment surface of the heated combing area, in particular being in direct contact with the teeth and/or the treatment surface in the heated combing area.
- the heating means may be resistance heaters or any other heating means.
- the teeth have a height of between 2 mm and 50 mm, and more preferably between 5 mm and 20 mm.
- the largest dimension of the teeth extending into the heated combing area which are heated by the heating means, in cross section of the tooth, is between 0.5 mm and 25 mm, preferably between 1 mm and 10 mm.
- the ratio between the height of a tooth and its largest cross-sectional dimension is greater than 1, preferably greater than 10.
- the teeth have no surface protrusions.
- At least some of the teeth, and preferably all of the teeth are attached to the brush, in particular fastened into holes in the treatment surface.
- at least some of the teeth, and preferably all of the teeth are formed as one with the treatment surface.
- the teeth may extend perpendicular to the treatment surface or be inclined relative to said treatment surface.
- the teeth of one row are spaced apart from each other by a distance of between 1 mm and 30 mm, and more preferably between 2 mm and 15 mm. The spacing is measured between the longitudinal axes of the teeth.
- the teeth are made from a heat-conductive material, in particular from iron, aluminum, titanium, stainless steel, graphite, or ceramic.
- the teeth made from a conductive material are preferably heated by the heating means.
- the teeth may be provided with a coating chosen from ceramic, tourmaline, elastomer, metal alloy and anodized coating materials. This allows the teeth to be heated easily by the heating means, and the hair to be in contact with hot surfaces in the heated combing area.
- Said teeth may comprise, at their end, a heat shield made from thermally insulating material in order to limit the heat in contact with the scalp.
- the maximum temperature at the end of said teeth may be less than or equal to 100°C, preferably less than or equal to 60°C, and more preferably less than 45°C.
- the brush may be configured such that, during operation, the temperature of said teeth halfway along their length is between 110°C and 230°C, preferably between 110°C and 210°C, and more preferably between 180°C and 210°C.
- the heat-conductive material has a thermal conductivity greater than 10 Wrn ⁇ K 1 , better than 50 Wm ⁇ K 1 , better than 100 Wm 'K 1 .
- the thermally conductive material is selected from metals, in particular copper, aluminium, iron and steel.
- the heat-conducting material may be ceramic.
- teeth may be made from a material with low heat conductivity, for example from elastomer or plastic.
- the material with low heat conductivity has a thermal conductivity comprised between 0,2 and 0,5 Wm _1 K _1
- the brush may comprise, along an axis perpendicular to the main axis of the brush, alternating rows of teeth made from a heat-conductive material and rows of teeth made from a material with low heat conductivity.
- the teeth made from a material with low heat conductivity may be of a different height, in particular taller, than the teeth made from a heat-conductive material. Having teeth with low heat conductivity that are taller than the heat-conductive teeth helps limit contact between the scalp and the heat-conductive teeth, the teeth with low heat conductivity coming into contact with the scalp before the heat-conductive teeth.
- the brush may comprise several steam outlets.
- the steam outlet or outlets extend in a steam outlet area of the brush delimited by the peripheral outer edges of the steam outlet or outlets, the steam outlet area extending along an axis of extension extending over more than 70%, and preferably more than 80%, of the dimension of the treatment surface along the axis of extension.
