A beverage brewing device with easy rejection of a capsule, comprising: a housing having a loading port and a dropping port; a first frame positioned inside a front portion of the housing; a second frame disposed inside a back portion of the housing and being movable forward and backward relative to the first frame, the second frame having a concave chamber for holding a capsule with a circular edge disposed at a front portion of the capsule; a holding mechanism, for receiving and holding the capsule after the capsule has been inserted between the first frame and the second frame; a stopping capsule plate positioned inside the housing and capable of being moved upward and downward, having a stopping portion extending backward to the upper and the rear of a rear surface of the first frame, and a spacing for receiving the circular edge of the capsule, being formed between the stopping portion and the rear surface of the first frame; and an elastic mechanism, acting on the stopping capsule plate and keeping the stopping capsule plate in a tendency of moving downward; the device being arranged so that: in the process of the second frame moving forward, the second frame can drive the capsule to release from the holding mechanism and to move forward along with the second frame; the circular edge of the capsule can be resisted against a rear end face of the stopping portion to force the stopping capsule plate to move forward overcoming the elastic mechanism; when the first frame and the second frame are closed with each other, the circular edge of the capsule enters into the spacing; and in the process of the second frame moving backward, the circular edge of the capsule is stopped by a front end face of the stopping portion and finally drops under the action of gravity. a housing having a loading port and a dropping port; a first frame positioned inside a front portion of the housing; a second frame disposed inside a back portion of the housing and being movable forward and backward relative to the first frame, the second frame having a concave chamber for holding a capsule with a circular edge disposed at a front portion of the capsule; a holding mechanism, for receiving and holding the capsule after the capsule has been inserted between the first frame and the second frame; a stopping capsule plate positioned inside the housing and capable of being moved upward and downward, having a stopping portion extending backward to the upper and the rear of a rear surface of the first frame, and a spacing for receiving the circular edge of the capsule, being formed between the stopping portion and the rear surface of the first frame; and an elastic mechanism, acting on the stopping capsule plate and keeping the stopping capsule plate in a tendency of moving downward; the device being arranged so that: in the process of the second frame moving forward, the second frame can drive the capsule to release from the holding mechanism and to move forward along with the second frame; the circular edge of the capsule can be resisted against a rear end face of the stopping portion to force the stopping capsule plate to move forward overcoming the elastic mechanism; when the first frame and the second frame are closed with each other, the circular edge of the capsule enters into the spacing; and in the process of the second frame moving backward, the circular edge of the capsule is stopped by a front end face of the stopping portion and finally drops under the action of gravity. in the process of the second frame moving forward, the second frame can drive the capsule to release from the holding mechanism and to move forward along with the second frame; the circular edge of the capsule can be resisted against a rear end face of the stopping portion to force the stopping capsule plate to move forward overcoming the elastic mechanism; when the first frame and the second frame are closed with each other, the circular edge of the capsule enters into the spacing; and in the process of the second frame moving backward, the circular edge of the capsule is stopped by a front end face of the stopping portion and finally drops under the action of gravity.
