Ces objectifs sont atteints selon l'invention par un accessoire pour appareil de mise en forme de cheveux destiné à s'adapter sur un appareil de coiffure électrique à flux d'air comprenant : un manchon creux présentant un axe longitudinal (L) capable de se monter sur l'appareil de coiffure, le manchon comprenant un ensemble de touffes de soies et un ensemble d'ouvertures traversantes aptes à faire passer le flux d'air, où le manchon présente une surface extérieure symétrique selon au moins le premier plan contenant l'axe longitudinal et un deuxième plan contenant l'axe longitudinal et orthogonal au premier plan et où la coupe de la surface extérieure du manchon selon un plan orthogonal à l'axe longitudinal définit une courbe fermée présentant un petit axe contenu dans le premier plan et un grand axe contenu dans le deuxième plan, le rapport grand axe divisé par petit axe étant supérieur ou égal à 1 ,1 . These objectives are achieved according to the invention by a device accessory for shaping hair adapted to fit on an electric airflow hairdressing apparatus comprising: a hollow sleeve having a longitudinal axis (L) capable of mounting on the hairdressing apparatus, the sleeve comprising a set of tufts of bristles and a set of through openings capable of passing the air flow, wherein the sleeve has a symmetrical outer surface in at least the first plane containing the longitudinal axis and a second plane containing the longitudinal axis and orthogonal in the foreground and where the section of the outer surface of the sleeve in a plane orthogonal to the longitudinal axis defines a closed curve having a small axis contained in the first plane and a major axis contained in the second plane, the divided major axis ratio by minor axis being greater than or equal to 1, 1.
Ces objectifs sont atteints également par un appareil de coiffure électrique à flux d'air comprenant une entrée d'air, un élément chauffant, un ventilateur, un moyen d'entraînement du ventilateur et une section de sortie d'air soufflé, caractérisé en ce qu'il comporte un accessoire de coiffure selon l'invention. These objectives are also achieved by an electric air-flow hairdresser comprising an air inlet, a heating element, a fan, a fan drive means and a blown air outlet section, characterized in that it comprises a hairdressing accessory according to the invention.
Les aspects principaux de l'invention sont les suivants : The main aspects of the invention are as follows:
L'invention concerne un accessoire (1 ) destiné à s'adapter sur un appareil de coiffure (100) électrique à flux d'air comprenant : un manchon (10) creux présentant un axe longitudinal (L) capable de se monter sur l'appareil de coiffure (100), le manchon (10) comprenant un ensemble de touffes de soies (1 1 , 1 1 ', 1 1 ") et un ensemble d'ouvertures traversantes (12) aptes à faire passer le flux d'air, caractérisé en ce que le manchon (10) présente une surface extérieure symétrique selon au moins le premier plan (P1 ) contenant l'axe longitudinal (L) et un deuxième plan (P2) contenant l'axe longitudinal (L) et orthogonal au premier plan (P1 ) et caractérisé en ce que la coupe de la surface extérieure (Sext) du manchon (10) selon un plan orthogonal à l'axe longitudinal (L) définit une courbe (C) fermée présentant un petit axe (r) contenu dans le premier plan (P1 ) et un grand axe (R) contenu dans le deuxième plan (P2), le rapport grand axe divisé par petit axe (R/r) étant supérieur ou égal à 1 ,1 .  The invention relates to an accessory (1) intended to fit on an electric airflow hairdressing appliance (100) comprising: a hollow sleeve (10) having a longitudinal axis (L) capable of being mounted on the hairdressing apparatus (100), the sleeve (10) comprising a set of bristle tufts (1 1, 1 1 ', 1 1 ") and a set of through openings (12) able to pass the air flow , characterized in that the sleeve (10) has a symmetrical outer surface in at least the first plane (P1) containing the longitudinal axis (L) and a second plane (P2) containing the longitudinal axis (L) and orthogonal to the foreground (P1) and characterized in that the section of the outer surface (Sext) of the sleeve (10) in a plane orthogonal to the longitudinal axis (L) defines a closed curve (C) having a minor axis (r) contained in the foreground (P1) and a major axis (R) contained in the second plane (P2), the major axis ratio divided by minor axis (R / r) being greater than or equal to 1, 1.
Cette forme de section à petit axe et grand axe, par exemple ovale, en section orthogonale à l'axe de symétrie (S) du manchon permet de ne plus fournir, comme pour un corps à section orthogonale circulaire ou ronde de l'art antérieur, un effort constant sur la mèche de cheveux. La forme extérieure différente de la forme circulaire permet, quand l'accessoire est entraîné en rotation, manuelle ou automatique, de fournir une traction et/ou une tension sur la mèche qui n'est pas constante et qui est plus forte quand la mèche est accrochée à l'une des deux extrémités de la brosse ovale : ceci renforce l'effet et la durabilité du brushing. De plus la mèche de cheveux restera en contact avec une plus grand surface donc les cheveux en contact avec la surface seront plus longtemps soumis à la traction et à l'air soufflé. Ceci permet de reproduire au mieux le geste du professionnel qui réalise le brushing avec une brosse dans la main et un sèche-cheveux dans l'autre main. Pour une rotation complète, le mouvement imprimé comporte deux fois le même traitement de la mèche de cheveux. On entend par surface extérieure du manchon ou de chaque corps la surface qui est destinée à être en contact avec la mèche de cheveux à traiter. Cette forme en section orthogonale à l'axe longitudinal de l'accessoire permet de ne plus fournir, comme pour un corps à section orthogonale circulaire ou rond de l'art antérieur, un effort constant sur la mèche de cheveux. La forme extérieure autre que circulaire permet, quand l'accessoire est entraîné en rotation manuelle ou automatique, de fournir une traction et/ou une tension sur la mèche qui n'est pas constante et ainsi de renforcer l'effet de brushing. Ceci permet aussi de reproduire au mieux le geste du professionnel qui réalise le brushing avec une brosse dans la main et un sèche-cheveux dans l'autre main. Cet accessoire est innovant en ce que son manchon ne présente pas, comme les appareils de coiffure soufflant connus, une forme tubulaire d'un rayon constant. This form of section with a small axis and major axis, for example oval, in section orthogonal to the axis of symmetry (S) of the sleeve makes it possible to no longer provide, as for a body of circular or round orthogonal section of the prior art, a constant force on the lock of hair. The different external shape of the circular shape allows, when the accessory is rotated, manual or automatic, to provide traction and / or tension on the wick which is not constant and which is stronger when the wick is attached to one end of the oval brush: this enhances the effect and durability of the brushing. In addition, the lock of hair will remain in contact with a larger surface so that the hair in contact with the surface will be longer subjected to traction and air blowing. This allows to reproduce at best the gesture of the professional who makes the brushing with a brush in the hand and a hair dryer in the other hand. For a complete rotation, the printed movement has twice the same treatment of the lock of hair. By outer surface of the sleeve or each body is meant the surface that is intended to be in contact with the lock of hair to be treated. This shape in section orthogonal to the longitudinal axis of the accessory makes it possible to no longer provide, as for a body with orthogonal circular or round section of the prior art, a constant force on the lock of hair. The external shape other than circular allows, when the accessory is driven in manual or automatic rotation, to provide traction and / or tension on the wick that is not constant and thus enhance the blow-drying effect. This also allows to reproduce at best the gesture of the professional who makes the brushing with a brush in the hand and a hairdryer in the other hand. This accessory is innovative in that its sleeve does not present, like known blower hairdressers, a tubular shape of a constant radius.
La section du manchon orthogonale à l'axe longitudinal peut être de toute forme géométrique à partir de laquelle nous pouvons définir un petit axe r de l'ovale et un grand axe R de l'ovale pour la bonne compréhension de l'invention. The section of the sleeve orthogonal to the longitudinal axis can be of any geometric form from which we can define a small axis r of the oval and a major axis R of the oval for the proper understanding of the invention.
On entend par «soies» tout type de poils, naturels ou synthétiques, de picots par exemple en plastique ou l'ensemble des deux poils et picots, qui permettent d'accrocher et/ou d'entraîner la mèche de cheveux pendant son traitement par l'accessoire-brosse. Les soies peuvent être de natures différentes, mais aussi de longueurs différentes, pour s'adapter à tout type de cheveux ou toute longueur de cheveux. Les soies peuvent être groupées par touffes de plusieurs ou être individuelles s'il s'agit de picot par exemple. The term "bristles" means any type of hair, natural or synthetic, of for example plastic pins or all of the two bristles and pins, which allow to hang and / or train the lock of hair during its treatment with the brush accessory. The bristles can be of different natures, but also of different lengths, to adapt to any type of hair or any length of hair. The bristles can be grouped by tufts of several or be individual if it is picnic for example.
Avantageusement, l'accessoire selon l'invention présente une coupe de la surface extérieure (Sext) du manchon (10) selon un plan orthogonal à l'axe longitudinal (L) définissant une courbe (C) fermée qui est un ovale présentant un petit axe (r) contenu dans le premier plan (P1 ) et un grand axe (R) contenu dans le deuxième plan (P2), le rapport grand axe divisé par petit axe (R r) étant supérieur ou égal àAdvantageously, the accessory according to the invention has a section of the outer surface (Sext) of the sleeve (10) in a plane orthogonal to the longitudinal axis (L) defining a closed curve (C) which is an oval presenting a small axis (r) contained in the first plane (P1) and a major axis (R) contained in the second plane (P2), the major axis ratio divided by minor axis (R r) being greater than or equal to
1 ,1 . 1, 1.
Avantageusement et alternativement au précédent mode, l'accessoire selon l'invention présente une coupe de la surface extérieure (Sext) du manchon (10) selon un plan orthogonal à l'axe longitudinal (L) définissant une courbe (C) fermée qui est une ellipse présentant un petit axe (r) contenu dans le premier plan (P1 ) et un grand axe (R) contenu dans le deuxième plan (P2), le rapport grand axe divisé par petit axe (R/r) étant supérieur ou égal à 1 ,1 . On rappelle que l'ovale et l'ellipse sont deux courbes planes, fermées, symétriques par rapport à un ou deux axes perpendiculaires. L'ovale est constitué par une succession d'arcs de cercle se raccordant les uns aux autres, l'ovale peut définir un ou deux axes de symétrie. L'ellipse est une courbe plane et définit deux axes de symétrie. C'est une conique telle que la somme des distances de chacun de ses points aux deux foyers est constante. L'ellipse se construit point par point.  Advantageously and alternatively to the previous mode, the accessory according to the invention has a section of the outer surface (Sext) of the sleeve (10) in a plane orthogonal to the longitudinal axis (L) defining a closed curve (C) which is an ellipse having a minor axis (r) contained in the first plane (P1) and a major axis (R) contained in the second plane (P2), the major axis ratio divided by minor axis (R / r) being greater than or equal to at 1, 1. It is recalled that the oval and the ellipse are two plane, closed curves, symmetrical with respect to one or two perpendicular axes. The oval is constituted by a succession of arcs of circle connected to each other, the oval can define one or two axes of symmetry. The ellipse is a plane curve and defines two axes of symmetry. It is a conic such that the sum of the distances from each of its points to the two foci is constant. The ellipse is built point by point.
Ainsi l'ovale présente une forme plus courbée au niveau des extrémités des grands axes en comparaison avec l'ellipse. La section elliptique sera avantageusement utilisée pour une coiffure nécessitant une grande traction sur les mèches de cheveux à brusher de façon souple mais pas très courbe. Tandis que la section ovale sera avantageusement utilisée pour une coiffure nécessitant une moindre traction sur les mèches de cheveux à brusher de façon souple et plus arrondie. Les deux sections fonctionnent très bien l'une et l'autre. Avantageusement, le rapport grand axe divisé par petit axe (R/r) de l'accessoire selon l'invention est compris entre 1 ,1 et 3 ; préférentiellement compris entre 1 ,3 et 2, substantiellement égal à environ 1 ,6. Plus le rapport de dimension est grand plus la traction exercée sur les cheveux à chaque passage en contact avec le point correspondant au grand axe sera grande. Thus the oval has a more curved shape at the ends of the major axes in comparison with the ellipse. The elliptical section will advantageously be used for a hairstyle requiring a great deal of traction on the locks of hair to be brusher in a flexible manner but not very curved. While the oval section will be advantageously used for a hairstyle requiring less traction on the locks of hair to brusher in a flexible and more rounded manner. Both sections work very well. Advantageously, the major axis ratio divided by small axis (R / r) of the accessory according to the invention is between 1, 1 and 3; preferably between 1, 3 and 2, substantially equal to about 1, 6. The larger the dimension ratio, the greater the tension exerted on the hair at each passage in contact with the point corresponding to the major axis.
Avantageusement, l'ensemble des touffes de soies (1 1 , 1 1 ', 1 1 ") peut comprendre au moins deux rangées droites (1 1 ) de touffes de soies parallèles à l'axe longitudinal (L) et agencées chacune sur la ligne définie par les deux extrémités du grand axe (R). Ceci permet d'entraîner la mèche traitée et de la soumettre à traction plus longtemps, pour un brushing plus efficace. Advantageously, the set of bristle tufts (1 1, 1 1 ', 1 1 ") may comprise at least two straight rows (1 1) of tufts of bristles parallel to the longitudinal axis (L) and each arranged on the line defined by both ends of the major axis (R) .This allows to drive the treated wick and subject it to traction longer, for a more effective brushing.
Avantageusement, l'ensemble de touffes de soies (1 1 , 1 1 ', 1 1 ") peut comprendre au moins une paire de rangées droites de touffes de soies (1 1 ', 1 1 ") agencées symétriquement par rapport au premier plan (P1 ) et au deuxième plan (P2). Ainsi les rangées seront reparties uniformément pour entraîner la mèche traitée sur toute la circonférence de la brosse. Avantageusement le manchon (10) peut présenter une base (14) apte à se monter sur une section de sortie (204) d'un appareil de coiffure électrique (100) à flux d'air. Ceci permet de réduire l'encombrement hors usage. Ceci permet aussi de proposer un kit appareil de coiffure avec plusieurs accessoires brosses détachables. Advantageously, the set of bristle tufts (1 1, 1 1 ', 1 1 ") may comprise at least one pair of straight rows of bristle tufts (1 1', 1 1") arranged symmetrically with respect to the foreground (P1) and in the second plane (P2). Thus the rows will be distributed evenly to drive the treated wick around the entire circumference of the brush. Advantageously, the sleeve (10) may have a base (14) adapted to be mounted on an outlet section (204) of an electric air-style hairdressing appliance (100). This reduces the clutter out of use. This also makes it possible to propose a hairdressing tool kit with several detachable brushes accessories.
L'appareil de coiffure (100) électrique à flux d'air selon l'invention comprend une entrée d'air (202), un élément chauffant (205), un ventilateur (207), un moyen d'entraînement du ventilateur (206) et une section de sortie (204) d'air soufflé, et comporte un accessoire de coiffure (1 ) selon l'invention. L'accessoire peut être fixé à demeure sur l'appareil. The electric airflow hairdressing apparatus (100) according to the invention comprises an air inlet (202), a heating element (205), a fan (207), a fan drive means (206). ) and an outlet section (204) blown air, and comprises a hairdressing accessory (1) according to the invention. The accessory can be permanently attached to the device.
Avantageusement, l'accessoire (1 ) peut être apte à se monter de façon détachable sur la section (204) de sortie d'air de l'appareil. Avantageusement, l'appareil peut être une brosse soufflante linéaire dont la poignée présente un axe longitudinal (Ι_') confondu ou parallèle à l'axe longitudinal (L) de l'accessoire (1 ). Ceci permet de réduire l'encombrement hors usage. Ceci permet aussi de proposer un ensemble appareil de coiffure avec plusieurs accessoires brosses détachables. Advantageously, the accessory (1) can be adapted to be mounted detachably on the section (204) of the air outlet of the device. Advantageously, the apparatus may be a linear blower brush whose handle has a longitudinal axis (Ι_ ') coincident or parallel to the longitudinal axis (L) of the accessory (1). This reduces the clutter out of use. This also makes it possible to propose a set of hairdressing apparatus with several accessories detachable brushes.
Alternativement, l'appareil peut être un sèche-cheveux de forme pistolet classique dont l'axe de l'accessoire sera substantiellement perpendiculaire à celui de la poignée de préhension. Cette forme permet à l'utilisateur de ne pas tordre son poignet en fonctionnement. Alternatively, the apparatus may be a conventional gun-shaped hair dryer whose axis of the accessory will be substantially perpendicular to that of the handle. This shape allows the user not to twist his wrist during operation.

La section orthogonale à l'axe longitudinal (L) de la surface extérieure (Sext) illustrée en figure 2 n'est pas circulaire ou ronde. La surface extérieure (Sext) du manchon est symétrique par rapport à au moins un deuxième plan (P2) orthogonal au premier plan (P1 ). Les axes de symétrie correspondant sensiblement au grand axe et au petit axe de l'ovale ou de l'ellipse. Figures 2 to 6 show the accessory according to the invention. It comprises a sleeve (10) defining a hollow body having a longitudinal axis (L) capable of being mounted on the hairdressing apparatus 100. The sleeve 10 comprises a set of bristle tufts for driving the hair (1 1, 1 1 ', 1 1 ") and a set of through openings (12) capable of passing the air flow The outer surface (Sext) of this sleeve (10) intended to come into contact with the hair is symmetrical with respect to at least a first plane (P1) coincident (as illustrated) or parallel to the longitudinal axis (L). The section orthogonal to the longitudinal axis (L) of the outer surface (Sext) illustrated in FIG. 2 is not circular or round. The outer surface (Sext) of the sleeve is symmetrical with respect to at least a second plane (P2) orthogonal to the first plane (P1). The axes of symmetry corresponding substantially to the major axis and the minor axis of the oval or ellipse.

Avant fonctionnement, quand l'accessoire est amovible, l'utilisateur peut choisir un accessoire et l'insérer dans la section de sortie de l'appareil jusqu'à ce qu'une protubérance circulaire interne à la section de sortie 204 du boîtier 200 rentre dans une rainure circulaire 47 de la base 14 correspondante. L'homme du métier peut envisager tout type de fixation comme des ergots qui arrivent au fond de baïonnettes. L'appareil est alors prêt à fonctionner, l'utilisateur actionne un bouton 220 de mise en marche du premier moteur 206 qui permet au flux d'air chaud de sortir par les ouvertures 12 de l'accessoire 1 . Un bouton 221 peut être prévu pour couper l'alimentation de l'élément chauffant 205 en vue d'un traitement avec de l'air à température ambiante. Un bouton peut également être prévu pour mettre en marche un générateur d'ions et enrichir d'ions le flux d'air soufflé par la poignée. En actionnant un bouton 222, l'utilisateur met en marche le deuxième moteur 206' d'entraînement de l'accessoire 1 qui commence alors à tourner pour réaliser la mise en forme de la coiffure. Ce bouton permet également d'inverser le sens de rotation du moteur 206 ou de faire varier sa vitesse. Before operation, when the accessory is removable, the user can choose an accessory and insert it into the output section of the apparatus until a circular protrusion internal to the outlet section 204 of the housing 200 enters in a circular groove 47 of the corresponding base 14. The man the craft can consider any type of fixation like pins that arrive at the bottom of bayonets. The apparatus is then ready for use, the user actuates a button 220 for starting the first motor 206 which allows the flow of hot air to exit through the openings 12 of the accessory 1. A button 221 may be provided to cut off power to the heating element 205 for treatment with room temperature air. A button may also be provided to turn on an ion generator and enrich the air flow blown by the handle with ions. By actuating a button 222, the user starts the second drive motor 206 'of the accessory 1 which then begins to rotate to achieve shaping of the hairstyle. This button also makes it possible to reverse the direction of rotation of the motor 206 or to vary its speed.
Ainsi, le fonctionnement et l'efficacité de la brosse munie de l'accessoire «ovale» ou «elliptique» sont démontrés par rapport à un accessoire totalement tubulaire à rayon constant. En effet, dans l'ordre de traitement quand les cheveux s'enroulent autour de la surface de traitement, la mèche est entraînée en traction par les soies 1 1 agencées sur la surface extérieure Sext du manchon et ensuite vient en contact avec la surface extérieure la moins «courbée» de l'ovale et les soies 1 1 ' et 1 1 ". La partie de mèche de cheveux entraînée par le grand sommet de l'ellipse ou ovale subit une plus forte tension que si l'accessoire était une brosse cylindrique au plus grand diamètre de l'ovale. La partie de mèche de cheveux en contact avec la surface la moins «courbée» présente une plus grande surface de contact du cheveux avec la surface de traitement que si le corps était un corps cylindrique, donc reçoit plus longtemps l'air soufflé, est sous traction plus longtemps et peut fixer la forme de la mèche de cheveux plus efficacement. Ceci permet un rendu «lissé volumant» sur les cheveux. Les cheveux ne sont jamais totalement enroulés autour de l'accessoire en bon fonctionnement de l'appareil. En effet, pour cet appareil électrique 100 de mise en forme des cheveux, l'accessoire 1 à cheveux est conformé de telle sorte que l'entraînement en rotation des cheveux ne se fait qu'à un certain point pour éviter en principe un enroulement complet de l'accessoire 1 dans les cheveux. Il faut une certaine vitesse de rotation afin de maintenir pendant le temps nécessaire les cheveux à mettre en forme dans la position qui produit l'ondulation à réaliser. La chaleur fournie par le flux d'air chaud soutient le processus de mise en forme des cheveux. La brosse à cheveux est judicieusement conformée à la manière d'une brosse à air et le flux d'air chaud arrive dans la brosse à cheveux pénétrant dans le canal d'admission interne de la brosse à cheveux et ressortant dans le sens radial par les ouvertures de sortie situées dans la brosse à cheveux. Thus, the operation and effectiveness of the brush provided with the "oval" or "elliptical" accessory are demonstrated with respect to a totally tubular constant radius accessory. Indeed, in the order of treatment when the hair is wrapped around the treatment surface, the wick is pulled by the bristles 1 1 arranged on the outer surface Sext of the sleeve and then comes into contact with the outer surface the least "curved" of the oval and the bristles 1 1 'and 1 1 ".The part of lock of hair driven by the large apex of the ellipse or oval undergoes a stronger tension than if the accessory was a brush cylindrical to the largest diameter of the oval The wick portion of hair in contact with the less "curved" surface has a greater area of contact of the hair with the treatment surface than if the body was a cylindrical body, so It has longer air intake, longer pulling time and can fix the shape of the lock of hair more effectively, this allows a "volumizing smoothing" effect on the hair. the accessory in good working order. Indeed, for this electrical appliance 100 for shaping the hair, the hair accessory 1 is shaped so that the rotation of the hair is only at a certain point to avoid in principle a complete winding of the accessory 1 in the hair. It takes a certain speed of rotation to maintain for the necessary time the hair to form in the position that produces the corrugation to achieve. The heat provided by the hot airflow supports the process of shaping the hair. The hairbrush is suitably shaped in the manner of an airbrush and the hot airflow is delivered into the hairbrush penetrating the internal intake channel of the hairbrush and radially outwardly exposed by the hairbrush. outlet openings located in the hairbrush.
L'entraînement limité en rotation des cheveux par la brosse est obtenu de sorte que la face supérieure du corps orientée radialement vers l'extérieur de la brosse présente des propriétés telles que celle-ci ne transmettra sensiblement aucun moment de rotation sur les cheveux. Cette surface est donc judicieusement très lisse et/ou présente un revêtement auquel les cheveux à mettre en forme n'adhèrent pas lors d'une rotation de la brosse à cheveux, tel que cela est par exemple le cas pour un revêtement en polytétrafluoroéthylène (revêtement PTFE). En configurant la surface du manchon 10 de la brosse à cheveux de cette manière, l'entraînement en rotation des cheveux à mettre en forme est majoritairement assuré par les poils ou soies de brosse. Ceux-ci sont conçus par leur densité et/ou leur rigidité de telle sorte que d'une part, l'entraînement en rotation des cheveux à mettre en forme s'effectue effectivement lors de la rotation de la brosse à cheveux, mais d'autre part, que cet entraînement en rotation ne s'effectue que sur une partie de la circonférence de la brosse à cheveux, par exemple entre 90° et 270°, plus particulièrement entre 135° et 235°; plus spécifiquement autour de 180°. Les flux d'air sortent radialement des ouvertures traversantes. The limited drive in rotation of the hair by the brush is obtained so that the upper face of the body oriented radially outwardly of the brush has properties such that it will transmit substantially no torque on the hair. This surface is therefore judiciously very smooth and / or has a coating to which the hair to be shaped does not adhere during a rotation of the hairbrush, as is for example the case for a coating of polytetrafluoroethylene (coating PTFE). By configuring the surface of the sleeve 10 of the hairbrush in this manner, the rotational drive of the hair to be shaped is mainly provided by the bristles or bristles. These are designed by their density and / or their rigidity so that on the one hand, the rotational drive of the hair to be shaped actually occurs during the rotation of the hair brush, but on the other hand, that this rotation drive takes place only on a part of the circumference of the hairbrush, for example between 90 ° and 270 °, more particularly between 135 ° and 235 °; more specifically around 180 °. The air flows radially out of the through openings.
D'autres variantes et modes de réalisation de l'invention peuvent être envisagés sans sortir du cadre de ses revendications. Other variants and embodiments of the invention may be envisaged without departing from the scope of its claims.
Ainsi, le moteur d'entraînement de l'accessoire peut être couplé à son arbre de sortie avec un mécanisme de transformation de son mouvement de rotation en un mouvement de translation alternative ou en un mouvement vibratoire, etc. à utiliser avec différents types d'accessoires. Thus, the drive motor of the accessory can be coupled to its output shaft with a mechanism for transforming its rotational movement into an alternative translatory motion or vibratory motion, etc. to use with different types of accessories.
Ainsi, l'appareil de coiffure soufflant peut être une brosse totalement longitudinale dont l'axe de l'accessoire est parallèle ou confondu avec l'axe du boîtier de préhension, ou bien peut être un sèche-cheveux de forme pistolet classique dont l'axe de l'accessoire est substantiellement perpendiculaire à celui de la poignée de préhension. Thus, the blowing hairdressing apparatus can be a totally longitudinal brush whose axis of the accessory is parallel or coincides with the axis of the gripping case, or can be a conventional gun-shaped hair dryer whose axis of the accessory is substantially perpendicular to that of the grip handle.
