Abstract

La présente demande se rapporte au domaine des appareils de beauté, et concerne un appareil de beauté de type à contact et une tête de fonctionnement d'un appareil de soins de la peau de type à contact. L'appareil de beauté de type à contact fourni par la présente demande comprend un élément de compresse froide, un élément de réfrigération, un élément de dissipation de chaleur et une tête d'électrode. L'élément de compresse froide comprend une surface de contact et une surface de conduction, la surface de contact étant utilisée pour entrer en contact avec le site cutané. Un côté de réfrigération de l'élément de réfrigération est couplé thermiquement à la surface de conduction de l'élément de compression froid de manière à refroidir l'élément de compresse froide. L'élément de dissipation de chaleur est couplé thermiquement à un côté chauffant de l'élément de réfrigération de manière à dissiper la chaleur de l'élément de réfrigération. La tête d'électrode est relativement fixée à l'élément de compresse froide. La tête d'électrode est fixée à l'élément de compresse froide. De cette façon, la structure redondante est réduite, et la conception est plus compacte. Parallèlement, aucune interférence d'une structure redondante ne se produit, de sorte que la sensation tactile sur le site cutané est plus agréable. La tête d'électrode offre des fonctions cosmétiques telles que la radiofréquence et le microcourant. Grâce à l'interaction de l'élément de compresse froide, de l'élément de réfrigération et de l'élément de dissipation de chaleur, un environnement de température approprié est fourni et l'effet cosmétique est amélioré davantage.
