For example, a Chinese invention patent entitled "Quantitative bagged ground coffee packaging and a pressure coffee machine using such a packaged coffee", which is patent number ZL94193279.6 (publication number CN1130345Y), discloses a coffee that allows the coffee bag to be automatically dropped. The machine structure, although the coffee machine can make the coffee bag fall off, it is necessary to specially design the structure for driving the rotation of the stopper, so that the structure is complicated, and the mechanical structure of the specific driving block rotation is not given in the specification.

To this end, the applicant invented a coffee machine with simple structure, reasonable operation, convenient operation and good hand feeling. The patent number is ZL200720110811.2 (announcement number is CN201044719Y), the Chinese utility model patent "automatic shedding mechanism of coffee bag in coffee machine" Disclosed is a coffee machine characterized in that a movable plate is connected to each side of the second machine member, and the front ends of the two clamping plates each have a blocking portion extending to the front end surface of the second mechanical member, and the two blocking portions are spaced apart. The front end of the splint can be stretched relative to the second mechanism, the front part of the splint is provided with a first axis in the height direction, and the rear part of the splint is provided with the second axis in the height direction, and the machine is arranged to be placed on the shelf. The seat is provided with two pairs of guiding grooves for guiding the first shaft and the upper and lower ends of the corresponding clamping plate, each pair of guiding grooves is composed of an upper guiding groove and a lower guiding groove, and in each pair of guiding grooves and corresponding first axis The guiding cooperation can drive at least one front end of the clamping plate relative to the second mechanism during the retraction of the second mechanism. A spring is provided in the cavity as a first element for improving the patent.

Although the structure of the aforementioned coffee machine has been improved, it has the drawback that the unpacking package is unreliable. If the spring is not disposed in the cavity of the first mechanism, it is necessary to pull the coffee bag out of the container by the adhesive force between the coffee bag and the front end surface of the second machine during the unpacking process, if the bonding force is small. It may happen that the presence of the coffee bag will remain in the cavity and the bag cannot be realized; if the cavity is provided with a spring, after the first and second parts are closed, the spring exerts a large force on the coffee bag, coffee The adhesive force between the bag and the front end surface of the second machine member is too large, and the coffee bag may be adsorbed on the front end surface of the second machine member during the unpacking process, so that the coffee bag is not easily peeled off even if the splint is opened; Set with a spring, after extraction, the spring will be soaked in the coffee beverage, which will contaminate the coffee beverage and affect the taste.

Therefore, the aforementioned patents can be further improved.
