Description

Technical Field

[0001] This utility model relates to the field of coffee machines, specifically to a brewing mechanism and a drawer-type coffee machine. Background Technology

[0002] A capsule holder structure for a capsule coffee machine includes a capsule holder assembly, a handle linkage assembly, and a brewing rack assembly. Coffee capsules are placed inside the capsule holder assembly, which is removably mounted onto the brewing rack assembly. The handle linkage assembly is movably connected to the brewing rack assembly. The handle linkage assembly includes a handle, a driving link, and a driven link. The brewing rack assembly includes a brewing tray and a brewing rack. Moving the handle up and down causes the driving link to drive the driven link, which in turn drives the brewing tray to reciprocate on the brewing rack. When the brewing tray moves downwards, it presses against and seals the capsule cap, allowing coffee brewing. When the brewing tray moves upwards, it separates from the capsule cap, allowing the capsule holder assembly to be pulled out for replacement of a new coffee capsule. This design, which uses a handle to drive the driving link, which in turn drives the driven link, which in turn drives the brewing tray, has disadvantages such as a large number of parts, complex structure, and inconvenient assembly. Furthermore, this design is only suitable for brewing coffee capsules and is not compatible with brewing cup-sized coffee powder. Utility Model Content
