the operating rod 300 is opened by clockwise swinging, the gear at the end of the operating rod 300 is engaged with and drives the transmission gear 302 to rotate, the transmission gear 302 is engaged with and drives the first connecting rod 304 to rotate around the shaft, because the first connecting rod 304 and the second connecting rod 307 are in a hinged relationship, and the second connecting rod 307 is in a hinged relationship with the water inlet bayonet holder 44 of the cup body assembly 40, when the operating rod 300 is rotated or pulled to open, the cup body assembly 40 moves horizontally and axially along the first direction in a direction away from the cup cover assembly 50, namely, moves towards the rear end.
When the cup body assembly 40 is far away from the cup cover assembly 50, the sliding portion 73 of the left positioning hook and the sliding portion 63 of the right positioning hook smoothly move towards the direction with small opposite positions under the spring force of the springs due to the fact that the restriction of the cup body assembly 40 on the cup body assembly is released, if the two positioning hook springs which move inwards to each side along the second direction are naturally released, at the moment, the vertical guide groove 631 of the right sliding portion 63 and the vertical guide groove 73 of the left sliding portion 73 are in the state of receiving the coffee capsule 90, the coffee capsule 90 is vertically placed into the coffee capsule brewing device from the coffee capsule inlet frame 11 at the top of the shell 10, namely, the coffee capsule 90 is vertically placed downwards along the up-down direction, the coffee capsule 90 slides in and is held along the two vertical guide grooves, then, the hand plate driving device is pulled reversely, the cup body assembly 40 horizontally moves towards the direction close to the cup cover assembly 50 along the first direction until the cup cover and the cup body assembly are pressed to form a sealed capsule box, the coffee capsule can be sealed, punctured, filled with water, brewed, discharged with coffee liquid and the like.
After the above operations are completed, the operating rod 300 is opened by swinging clockwise, the cup body assembly 40 drives the empty cup body of the coffee capsule 90 to separate from the cup cover 50 assembly, at this time, the ejection hook springs, namely the ejection hook left spring 71 and the ejection hook right spring 61 are still pressed by the conical inclined surface of the cup body assembly 40, so that a plurality of ejection fulcrums of the ejection hooks rotate around the axes of the ejection hooks to extrude towards the annular edge of the coffee capsule 90, that is, in the process of moving the cup body assembly 40 backward, the ejection supporting points of the left ejection hook 72 such as the left upper hook claw and the left lower hook claw, and the ejection supporting points of the right ejection hook 62 such as the right upper hook claw 6211 and the right lower hook claw 6212 axially limit the annular edge of the coffee capsule 90 in the cup body assembly 40 and make the coffee capsule 90 and the cup body assembly 40 stably ejected and separated, and falls out of the coffee capsule outlet 13 at the bottom end of the housing 10 under the weight of the coffee capsule 90 itself.
The above-described left and right, up and down, and front and back are for convenience of description and should not be construed as limiting the present invention.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
