Drink extraction mechanism

Abstract

A beverage extraction mechanism comprises a beverage brewing mechanism (26) assembled on a brewing base (25) and a driving mechanism (27) for driving the beverage brewing mechanism (26) to be opened, closed and turned. The driving mechanism (27) is guided by a motion guide mechanism (7) to drive the beverage brewing mechanism (26) to be opened, closed and turned. Furthermore, when the beverage brewing mechanism (26) is opened or closed, the opening part of a brewing cavity (19) is upward or inclined upwardly. The driving mechanism (27) is also connected with a pushing mechanism (31,32,33), which is used for ejecting out a capsule (23) still adsorbed on the brewing base (25) after coffee is brewed and boiled by the dink brewing mechanism (26) and the brewing cavity (19) in the dink brewing mechanism (26) is gradually separated from the coffee capsule (23). The beverage extraction mechanism is simple and rational in structure, more convenient for holding capsules, high degree in safety and more reliable in performance.

Description

Technical field [0001] The invention is a beverage extraction mechanism, in particular, an automatic capsule-removing coffee machine, which belongs to the transformation technology of the capsule coffee machine. Background technique [0002] Existing capsule coffee machines, such as the automatic capsule-removing coffee machine disclosed in Chinese Patent Document No. CN201571956U on September 8, 2010, include a beverage brewing mechanism and a driving mechanism that open and close in a straight line through a driving mechanism. The brewing mechanism is provided with a brewing cavity for loading coffee capsules, and the inner end of the driving mechanism is provided with a hot water channel and a one-way valve for brewing coffee capsules; the coffee capsule is provided with an annular flange on the surface, and the brewing cavity is fixedly arranged in the beverage brewing mechanism At the inner end, the opening into which the coffee capsule is loaded faces the hot water channel ...

AI Technical Summary

Problems solved by technology

However, the disadvantage of this structure is that when the capsule is placed vertically into the coffee capsule, there is a certain lack in use, and there is no mechanical pre-brewing function

In addition, during the use of the capsule coffee machine, due to the high pressure when making coffee, a vacuum is sometimes generated between the capsule and the sealing ring after cooking. At this time, the capsule is firmly sucked by the sealing ring and cannot be automatically dropped immediately Affecting its normal work, at this time, it is necessary to apply a certain external force to the capsule to push the capsule away from the sealing ring, and a capsule ejection mechanism is needed to realize it. WO2011036215A2 patent discloses a top capsule structure, but its top capsule structure is in the When ejecting the capsule, the ejector rod always exerts force on the capsule, the structure is complicated and the operation is inconvenient

In addition, the European patent number EP1757212B1 of the coffee machine applied by Nestlé, the beverage brewing mechanism will encounter the movable clamp block (that is, the capsule removal mechanism) during operation, which directly affects the safety and stability of the use.
