Patent ID: 8079300

Claim:
An automatic ejecting device for capsules in a coffee machine comprising: a housing, a first frame and a second frame both mounted in said housing, said second frame designed to be movable forward and backward relative to said first frame, said first frame and the second frame forming a hermetic chamber after hermetically closing so as to contain the capsule, a driving system also being mounted in the housing to close and open said first frame and second frame; two jaws movably jointing with two sides of said second frame respectively, the front portion of each jaw bending and extending to the front surface of said second frame to form a limiting part, these two limiting parts being set apart so as to limit the movement of the capsule, and the front portion of each jaw being able to splay and close relative to said second frame; a first shaft being mounted on the front of each jaw vertically, and a second shaft being mounted on the rear of each jaw vertically, two pairs of guiding grooves being mounted on the housing, the ends of said first and second shafts on the jaws being slid-able in the guiding grooves, respectively, each pair of guiding grooves comprising an upper guiding groove and a lower guiding groove for guiding the first shaft, therefore enabling the front portion of each jaw to complete at least one splaying and one closing when said second frame is moving backward.
