Abstract

Le présent modèle d'utilité concerne un instrument de beauté et une source d'alimentation électrique associée. La source d'alimentation intègre deux modes d'alimentation, à savoir un mode d'alimentation externe et un mode d'alimentation par stockage d'énergie intégré. Pendant un processus d'alimentation, si une source d'alimentation externe se trouve à côté d'un utilisateur, l'utilisateur fait passer une troisième partie de branchement de la source d'alimentation externe par une première interface et la branche électriquement dans une première partie de branchement, puis l'utilisateur fait passer une quatrième partie de branchement sur un corps d'instrument par une seconde interface et la branche électriquement dans une deuxième partie de branchement. À ce moment, une carte de circuit imprimé est respectivement en communication électrique avec la première partie de branchement et la deuxième partie de branchement, et un courant d'alimentation passe séquentiellement par la troisième partie de branchement, la première partie de branchement, la carte de circuit imprimé, la deuxième partie de branchement et la quatrième partie de branchement. Lorsqu'il n'y a pas de source d'alimentation externe à côté de l'utilisateur, ce dernier fait passer directement la quatrième partie de branchement du corps de l'instrument par la seconde interface et la branche dans la deuxième partie de branchement. À ce moment, la carte de circuit imprimé est respectivement en communication électrique avec un module de stockage d'énergie et la deuxième partie de branchement, et un courant d'alimentation passe séquentiellement par la carte de circuit imprimé, la deuxième partie de branchement et la quatrième partie de branchement, de sorte que le mode d'alimentation par stockage d'énergie intégré fonctionne.
