Abstract

Ensemble de déverrouillage (300) et cartouche d'encre (100). L'ensemble de déverrouillage (300) est monté dans la cartouche d'encre (100), la cartouche d'encre (100) peut être verrouillée au moyen d'un élément de verrouillage (200) dans une imprimante à jet d'encre, une surface de verrouillage (203) qui peut venir en butée contre une surface de limitation (105) dans la cartouche d'encre (100) est formée au niveau d'une extrémité avant de l'élément de verrouillage (200), et l'élément de verrouillage (200) peut tourner dans son ensemble autour d'un axe (L) passant à travers l'élément de verrouillage (200) dans un sens gauche-droite. L'ensemble de déverrouillage (300) comprend un élément de réception de force (71, 81, 91) et un élément mobile (72, 82, 92), l'élément de réception de force (71, 81, 91) étant utilisé pour recevoir une force d'action appliquée de haut en bas ; et l'élément mobile (72, 82, 92) est conçu pour pouvoir coulisser le long d'une partie de guidage bombée (107, 108, 109) disposée dans la cartouche d'encre (100), de manière à libérer le verrouillage de la cartouche d'encre (100). L'ensemble de déverrouillage (300) est dans une première position lorsque aucune force d'action n'est reçue par l'élément mobile (72, 82, 92), un point spécifique (P) dans l'élément mobile (72, 82, 92) dans une direction verticale ayant un premier point de saillie sur l'élément de verrouillage (200) ; et l'ensemble de déverrouillage (300) atteint une seconde position lorsque l'élément mobile (72, 82, 92) reçoit une force d'action, le point spécifique (P) dans l'élément mobile (72, 82, 92) ayant un second point de saillie sur l'élément de verrouillage (200), le second point de saillie étant situé devant le premier point de saillie dans un sens avant-arrière.
