Abstract: An automatic puncture mechanism of a capsule coffee machine, which is used puncture a side wall and a top wall of a coffee capsule, including a support unit with an upper support and a lower support, a linkage unit assembled to the upper support, a first puncture unit assembled to the upper support to perforate the top wall of the coffee capsule driven by the linkage unit, a carrying base assembled to the lower support to hold the coffee capsule, and a second puncture unit assembled to the lower support to perforate the side wall of the coffee capsule driven by the linkage unit. With the linkage unit, when the upper support moves to the lower support, it drives the first puncture unit and the second puncture unit to perforate the top wall and the side wall of the coffee capsule respectively, thus making the coffee machine easier to operate.

Abstract: A device for expelling used capsules of a capsule coffee machine includes a support unit, a receiving seat and a linkage control unit, the support unit has a lower support and an upper support pivotally connected together; the receiving seat is pivotally connected to the lower support of the support unit for receiving a coffee capsule; and the linkage control unit with a pull plate is connected to the upper support and a switch plate pivotally connected to the lower support of the support unit; when the upper support swings upwardly, the pull plates moves upwardly and pulls up the switch plate and the switch plate raises the receiving seat from a receiving position to an overturning position. With the linkage control unit, when the upper support swings it drives the receiving seat with a coffee capsule to expel the coffee capsule out of the receiving seat automatically.
