Description

hair treatment brush

The present invention relates to hair treatment brushes and corresponding hair treatment processes.

In the field of hairstyling, the use of hair brushes is common practice. Many improvements to traditional hair brushes have been proposed. Among these improvements, the combined use of steam has been the subject of many proposals. Patent application DE19822718 refers to a comb in which teeth can be perforated to release steam in contact with the hair. Alternatively, the brush does not have a steam outlet nozzle and the teeth are heated by a heating resistor without steam being applied. These brushes, which have perforated teeth heated by steam, can be relatively difficult to manufacture and tend to limit the temperature transferred to the hair. It can also result in uneven treatment due to the steam being over-focused locally on certain parts of the hair.

There are also documents describing hairstyling brushes that emit steam through a base carrying bristles or teeth during treatment, the latter acting as a heating means. For example, documents US4936027, JPS5568318, JPH07213325, CN2061786, JPH01207001, JPH1033253, JPH07163416, JP2000175723 and KR19990036306U may be cited. None of the documents on this list mention that the bristles or teeth themselves can be heated independently of the release of steam.

Patent application KR20030085159A describes a brush comprising a plurality of teeth heated by a heating resistor at the base and having steam outlets between the teeth. In these documents, the steam outlets and teeth are distributed over the entire surface of the brush. Accordingly, such brushes do not allow steam to be applied to restricted parts of the hair and the action of the steam to dissociate from the action of the drying heat.

There remains a need for brushes that are relatively uniform, durable, yet safe, and provide improved treatment performance, especially in terms of combing.

The present invention fulfills this need with the help of a hair treatment brush, especially for straightening, which hair treatment brush has:

- multiple teeth,

- comprising at least one steam outlet for releasing steam onto the hair,

The brush moves the steam through the steam outlet at a speed between 0.007 m/s and 15 m/s, preferably between 0.01 m/s and 3 m/s, more preferably between 0.1 m/s and 1 m/s. It is configured to emit at a rate of

The term “ brush ” should be understood to mean a hair treatment device consisting of a single arm with a plurality of teeth between which the hair is received as the brush passes through the hair. The brush may comprise a single row of teeth or preferably may comprise a plurality of rows of teeth.

“Teeth ” should be understood to mean elements that protrude from the brush between which the hair is received when the brush passes through the hair. The teeth can have any shape.

These brushes can effectively treat hair by brushing the hair in a single movement and applying steam to the brush. The specific speed range of the steam allows the steam to fully penetrate the hair during the treatment, limiting the risk of discomfort to the scalp that can result if the steam speed is too high, especially for thick strands of hair. improve treatment.

Preferably, the brush has an elongated shape along its main axis.

As a variant, the brush has a different, non-elongated shape.

Preferably, the brush includes a handle and a head. The handle makes the brush easier to hold and allows additional elements to be added to the brush, particularly a user interface, water or cosmetic product reservoir, and/or one or more sensors.

The head of the brush may have any cross-sectional shape. Preferably, the head of the brush has a substantially polygonal cross-section, in particular substantially rectangular or substantially square, substantially oval or substantially circular.

Preferably, the brush comprises a treatment surface and the teeth extend from the treatment surface. Preferably, this treatment surface is bulged or planar towards the outside. Preferably, this treatment surface has a substantially polygonal outline, in particular rectangular or square, circular or oval.

teeth

The teeth may extend in a row of at least one tooth, and preferably in a row of two teeth, each preferably extending parallel to the main axis of the brush.

Preferably, the brush is substantially rectangular and the teeth extend in rows of several 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.

Preferably, the row or rows of teeth each comprise at least 3 teeth, preferably 10 to 40 teeth, and more preferably 15 to 40 teeth.

Preferably, 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 of the teeth. Combining heating of the teeth and application of steam helps to improve the treatment of the hair. In particular, it allows higher temperatures to be maintained in the steam application spaces, especially in the spaces between the teeth when steam is projected into these spaces. It also allows the hair to be heated with dry heat before or after the application of steam, thereby improving steam treatment of the hair.

Preferably, the heating means comprises 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, which in particular form a core of the corresponding teeth.

The means for heating the teeth of the heated combing zone heats teeth extending at least partially below the treatment surface of the heated combing zone, in particular the teeth and/or the treatment surface in the heated combing zone. It may contain at least one active element in direct contact. The heating means may be a resistance heater or any other heating means.

The teeth made of conductive material are preferably heated by heating means. The teeth may be provided with a coating selected from ceramics, tourmalines, elastomers, metal alloys and anodized coating materials. This allows the teeth to be easily heated by the heating means, allowing the hair to come into contact with the hot surface of the heated combing zone. The teeth may include at their ends a heat shield made of insulating material to limit heat contacting the scalp. In this case, during operation, the maximum temperature at the ends of the teeth may be below 100°C, preferably below 60°C, and more preferably below 45°C. The brush may be configured such that during operation, the temperature of the teeth midway along its length is between 110°C and 230°C, preferably between 110°C and 210°C, and more preferably between 180°C and 210°C.

Preferably, the heat-conductive material has a thermal conductivity greater than 10 Wm ^-1 K ^-1 , preferably greater than 50 Wm ^-1 K ^-1 , more preferably greater than 100 Wm ^-1 K ^-1 . Preferably, the heat-conducting material is selected from metals, especially copper, aluminum, iron and steel. Alternatively, the thermally conductive material may be ceramic.

Some of the teeth may be made of a material with low heat-conductivity, for example an elastomer or plastic.

The brush may comprise rows of teeth made of a heat-conducting material and rows of teeth made of a material with low thermal conductivity alternating along an axis perpendicular to the main axis of the brush.

Teeth made of a material with low heat-conductivity may have a different height, especially a greater height, than teeth made of a heat-conducting material. If the low thermal conductivity teeth are larger than the thermally conductive teeth, this helps limit contact between the scalp and the thermally conductive teeth, with the low thermal conductivity teeth contacting the scalp before the thermally conductive teeth. I do it.

The steam outlet zone or zones may extend for only a portion of the length of the heated combing zone as shown in FIG. 12 .

In the example shown in FIG. 14 , the teeth 23 are inclined relative to the treatment surface 21 by an angle α between 45° and 90°. The steam outlet or outlets 30 is positioned at an angle different from 90° relative to the treatment surface 21, in particular between 45° and 90°, for example substantially equal to the angle α of the teeth 23. Steam can be released at an angle.
