Abstract

L'invention concerne un ensemble de chauffage électrique (100) et un dispositif de chauffage électrique (300). Un ensemble de chauffage électrique (100) comprend un corps de réception (11), un film d'enveloppement (12), un circuit de chauffage (13), et un groupe de broches externes (14) ; le corps de réception (11) présente une cavité de réception (113) pour recevoir une substance à chauffer ; le film d'enveloppement (12) enveloppe la surface externe du corps de réception (11) ; le circuit de chauffage (13) est disposé entre le corps de réception (11) et le film d'enveloppement (12), et est utilisé pour chauffer lors de la mise sous tension de manière à chauffer la substance à chauffer ; et le groupe de broches externes (14) est disposé sur la surface du film d'enveloppement (12) à l'opposé du corps de réception (11), est électriquement connecté au circuit de chauffage (13), et est électriquement connecté à un ensemble source d'alimentation (200). L'ensemble de chauffage électrique (100) peut réaliser une connexion sans plomb entre l'ensemble de chauffage électrique (100) et l'ensemble source d'alimentation (200), de telle sorte que le processus de désassemblage entre l'ensemble de chauffage électrique (100) et l'ensemble source d'alimentation (200) soit relativement simple, ce qui facilite le nettoyage de l'ensemble de chauffage électrique (100), et réduit considérablement l'influence, en raison d'un mauvais nettoyage, sur le goût de chauffage de la substance à chauffer ultérieurement.
