On a whim, the coffee machine design was seen in the milk tea shop before. When they sealed the plastic cover for the prepared milk tea, there was a pressing mechanism. I felt that this man-machine operation was very interesting. Thinking that when the capsule coffee is put into the coffee machine, it should be very interesting and convenient to make a similar switch, press down the handle, then turn on the mechanism, sink the front part of the coffee extrusion mechanism, and then slowly flow out the coffee.
