Abstract

L'invention concerne un mécanisme de perçage et un appareil de préparation de boisson. Le mécanisme de perçage comprend un corps (1) et, disposé sur le corps (1), un élément de perçage et un élément d'entonnoir (2). L'élément de perçage comprend une aiguille de perçage (3). L'élément d'entonnoir (2) comprend une capsule (4) agencée au-dessous de l'aiguille de perçage (3) et une aiguille de perçage inférieure (5) disposée sous la capsule (4). Le mécanisme de perçage comprend également un moteur (6) et un pignon (8) relié au moteur (6) par le biais d'un arbre (7). L'élément de perçage comprend également une crémaillère (9) mise en prise avec le pignon (8). L'aiguille de perçage (3) est disposée au-dessous de la crémaillère (9). Lorsque le moteur (6) entraîne l'arbre (7) en rotation dans la direction avant, la crémaillère (9) entraîne l'aiguille de perçage (3) à se déplacer vers le bas, l'aiguille de perçage (3) perce la capsule (4) et la capsule (4) est entraînée vers le bas pour être percée par l'aiguille de perçage inférieure (5) ; lorsque le moteur (6) entraîne l'arbre (7) en rotation dans la direction inverse, la crémaillère (9) se déplace vers le haut, l'aiguille de perçage (3) est entraînée vers le haut et à l'opposé de la capsule (4). En utilisant conjointement le pignon (8) et la crémaillère (9) pour percer la capsule (4), des forces sont appliquées de manière uniforme sur la capsule (4) et, ainsi, ne provoquent pas facilement l'éclatement de l'emballage ; la structure est simple et la commande est fiable.
