The vaporization device 19 more particularly comprises a vaporization chamber 21 in which at least a portion of the fluid conveying element 18 is placed when the reservoir 13 is in the vaporization position. The vaporization device 19 further comprises a vaporization surface 22 partially delimiting the vaporization chamber 21, and a heating element 23 configured to heat the vaporization surface 22. The heating element 23 may for example be a resistive element, such as that a thermistor with a positive temperature coefficient, called CTP.
Le réservoir 13 est plus particulièrement monté mobile selon une direction de déplacement D entre une position de repos (voir la figure 2) dans laquelle l'élément de convoyage de fluide 18 est éloigné de la surface de vaporisation 22, et une position de vaporisation (voir la figure 6) dans laquelle l'élément de convoyage de fluide 18 est rapproché de la surface de vaporisation 22, et par exemple en contact avec la surface de vaporisation 22, et le dispositif de vaporisation 19 est configuré pour vaporiser le fluide convoyé par l'élément de convoyage de fluide 18. Avantageusement, la direction de déplacement D du réservoir 13 est sensiblement parallèle à la direction d'extension du premier bras 5. Il convient d'être noté que l'unité de traitement portable 3 comprend avantageusement un ou plusieurs élément(s) de rappel 24 (voir la figure 4) configuré(s) pour rappeler le réservoir 13 vers la position de repos. Le ou chaque élément de rappel 24 peut par exemple être formé par un ressort hélicoïdal.  The reservoir 13 is more particularly mounted movable in a direction of displacement D between a rest position (see FIG. 2) in which the fluid conveying element 18 is remote from the vaporization surface 22, and a vaporization position ( see Figure 6) in which the fluid conveying element 18 is brought closer to the vaporization surface 22, and for example in contact with the vaporization surface 22, and the vaporization device 19 is configured to vaporize the fluid conveyed by the fluid conveying element 18. Advantageously, the displacement direction D of the reservoir 13 is substantially parallel to the direction of extension of the first arm 5. It should be noted that the portable processing unit 3 advantageously comprises a or several return element (s) 24 (see Figure 4) configured (s) to recall the reservoir 13 to the rest position. The or each return element 24 may for example be formed by a helical spring.
L'unité de traitement portable 3 comprend de plus un élément d'actionnement 25 monté sur la deuxième partie de préhension 6.1, et configuré pour déplacer le réservoir 13 de la position de repos à la position de vaporisation lorsque les premier et deuxième bras 5, 6 sont déplacés de la configuration écartée à la configuration rapprochée. L'élément d'actionnement 25 comporte une surface de came 26 configurée pour coopérer avec le réservoir 13, et plus particulièrement avec une portion d'extrémité du réservoir 13 opposée au dispositif de vaporisation 19. The portable processing unit 3 further comprises an actuating element 25 mounted on the second gripping portion 6.1, and configured to move the reservoir 13 from the rest position to the vaporization position when the first and second arms 5, 6 are moved from the remote configuration to the close configuration. The actuating element 25 comprises a cam surface 26 configured to cooperate with the reservoir 13, and more particularly with an end portion of the reservoir 13 opposite the vaporization device 19.
Selon le mode de réalisation représenté sur les figures 1 à 7, la surface de came 26 présente un profil curviligne continu, et comporte une succession de portions de surface de came présentant des rayons de courbure différents. La surface de came 26 est plus particulièrement configurée de telle sorte que chaque portion de surface de came présente un rayon de courbure supérieur au rayon de courbure de la portion de surface de came qui la précède. Selon ce mode de réalisation, la surface de came 26 est sensiblement en développante de cercle.  According to the embodiment shown in Figures 1 to 7, the cam surface 26 has a continuous curvilinear profile, and comprises a succession of cam surface portions having different radii of curvature. The cam surface 26 is more particularly configured so that each cam surface portion has a radius of curvature greater than the radius of curvature of the cam surface portion that precedes it. According to this embodiment, the cam surface 26 is substantially involute in a circle.
En outre, selon le mode de réalisation représenté sur les figures 1 à 7, l'élément d'actionnement 25 est monté pivotant sur la première partie de préhension 5.1 autour d'un axe de pivotement A, et l'unité de traitement portable 3 comporte en outre un élément de sollicitation 27, tel qu'un ressort de compression ou un ressort de torsion, configuré pour solliciter l'élément d'actionnement 25 vers une position d'actionnement dans laquelle l'élément d'actionnement 25 est apte à exercer un effort de poussée sur le réservoir 13. L'élément de sollicitation 27 est plus particulièrement configuré pour solliciter en rotation l'élément d'actionnement 25 de manière à éloigner l'extrémité de la surface de came 26, opposée à l'axe de pivotement A, du deuxième bras 6.  In addition, according to the embodiment shown in Figures 1 to 7, the actuating element 25 is pivotally mounted on the first gripping portion 5.1 around a pivot axis A, and the portable treatment unit 3 further comprises a biasing member 27, such as a compression spring or a torsion spring, configured to urge the actuating member 25 to an actuating position in which the actuating member 25 is adapted to exerting a thrust force on the reservoir 13. The biasing element 27 is more particularly configured to urge the actuating element 25 in rotation so as to move the end of the cam surface 26 away from the axis pivoting A, the second arm 6.
Une telle configuration de la surface de came 26 permet à l'élément d'actionnement 25 d'appliquer une force plus constante sur le réservoir 13 lorsque les première et deuxième partie de préhension 5.1, 6.1 sont déplacées dans la configuration rapprochée, et donc d'améliorer les performances de l'appareil de coiffure 2. En outre, une telle configuration de la surface de came 26 permet, en cas d'usure de l'élément de convoyage de fluide 18, d'augmenter la course de déplacement du réservoir 13 vers sa position de vaporisation, et donc de maintenir sensiblement constante, au cours du temps, la pression exercée par le dispositif de vaporisation 19 sur l'élément de convoyage de fluide 18 lorsque les premier et deuxième bras 5, 6 sont dans la configuration rapprochée. Il en résulte le maintien d'un débit de vapeur sensiblement constant au cours du temps, malgré l'usure de l'élément de convoyage de fluide 18.  Such a configuration of the cam surface 26 allows the actuating member 25 to apply a more constant force to the reservoir 13 when the first and second gripping portions 5.1, 6.1 are moved in the close configuration, and thus In addition, such a configuration of the cam surface 26 makes it possible, in the event of wear of the fluid conveying element 18, to increase the displacement path of the reservoir. 13 to its vaporization position, and thus to maintain substantially constant, over time, the pressure exerted by the vaporization device 19 on the fluid conveying element 18 when the first and second arms 5, 6 are in the configuration close. This results in the maintenance of a substantially constant steam flow over time, despite the wear of the fluid conveying element 18.
De plus, un tel montage de l'élément d'actionnement 25 sur la deuxième partie de préhension 6.1 et la présence de l'élément de sollicitation 27 permettent de compenser les tolérances de fabrication notamment des premier et deuxième bras 5, 6, du réservoir 13, de l'élément de convoyage de fluide 18 et de l'élément d'actionnement 25, et donc d'assurer un débit de vapeur optimal, et donc un niveau de performances optimal de l'appareil de coiffure 2. Ces dispositions permettent également de ne pas être tributaire de l'effort d'appui exercé par l'utilisateur sur les première et deuxième parties de préhension 5.1, 6.1, et donc de garantir un débit sensiblement constant quel que soit l'effort exercé par l'utilisateur sur les premier et deuxième bras 5, 6. In addition, such an assembly of the actuating element 25 on the second gripping portion 6.1 and the presence of the biasing element 27 make it possible to compensate for the manufacturing tolerances, in particular of the first and second arms 5, 6, of the reservoir 13, of the fluid conveying element 18 and of the actuating element 25, and thus to ensure an optimum steam flow rate, and therefore an optimum level of performance of the hairdressing apparatus 2 These arrangements also make it possible not to be dependent on the support force exerted by the user on the first and second gripping parts 5.1, 6.1, and thus to guarantee a substantially constant flow whatever the force exerted by the user on the first and second arms 5, 6.
L'unité de traitement portable 3 comprend en outre un dispositif de diffusion de vapeur 28 relié fluidiquement au dispositif de vaporisation 19, et configuré pour diffuser la vapeur générée par le dispositif de vaporisation 19 au niveau de la première surface de contact 7, et en particulier en direction de la deuxième surface de contact 8, lorsque les premier et deuxième bras 5, 6 sont dans la configuration rapprochée.  The portable processing unit 3 further comprises a vapor diffusion device 28 fluidly connected to the vaporizer 19, and configured to diffuse the vapor generated by the vaporizer 19 at the first contact surface 7, and particularly in the direction of the second contact surface 8, when the first and second arms 5, 6 are in the close configuration.

Avantageusement, les orifices de diffusion 32 sont régulièrement répartis le long de la rainure 29. Il convient d'être noté que la deuxième surface de contact 8 peut avantageusement comporter une rainure de confinement 33 configurée pour être disposée en vis-à-vis de la rainure 29 lorsque les premier et deuxième bras 5, 6 sont dans la configuration rapprochée, de manière à confiner la vapeur diffusée par les orifices de diffusion 32.  According to the embodiment shown in Figures 1 to 7, the first contact surface 7 comprises a groove 29 provided with a bottom 31, and the vapor diffusion device 28 comprises a plurality of diffusion orifices 32 fluidly connected to the vaporization chamber 21, and opening into the bottom 31 of the groove 29.
