Abstract

La présente invention concerne un masque, comprenant une face de masque et des portions de crochets auriculaires reliées de façon détachable aux extrémités gauche et droite de la face de masque, la face de masque comprenant une première couche de maille conductrice, une couche isolante et perméable à l'air, et une seconde couche de maille conductrice, qui sont successivement fixées de l'extérieur vers l'intérieur. La première couche de maille conductrice est électriquement connectée à l'électrode positive d'un dispositif d'alimentation électrique, et la seconde couche de maille conductrice est électriquement connectée à l'électrode négative du dispositif d'alimentation électrique. Des portions d'extrémité s'étendant vers l'arrière d'une joue humaine sont formées sur les extrémités gauche et droite de la face de masque, et une interface du dispositif d'alimentation électrique est disposée à proximité des portions d'extrémité. Les portions de crochets auriculaires comprennent un crochet auriculaire de forme annulaire et un segment d'extension qui sont agencés dans l'ordre le long de la direction d'extension des portions d'extrémité. Les extrémités avant des crochets auriculaires de forme annulaire sont reliées aux portions d'extrémité, et leurs extrémités sont formées d'un seul tenant avec les segments d'extension. Le présent masque peut améliorer le degré d'étanchéité et éviter la douleur occasionnée à l'oreille par le port à long terme.
