Abstract
Description
Technical Field
[0001] This utility model relates to a coffee brewing apparatus. Background Technology
[0002] Current technology, specifically Chinese patent 201910346915.0, describes a capsule brewing structure, including a handle, a brewing support, a brewing head, a capsule holder, and a capsule puncture mechanism. The brewing head moves up and down within the brewing support to engage or disengage with the capsule holder. It also includes a four-bar linkage connecting the handle and the brewing head; rotation of the handle synchronously drives the brewing head's movement. Compared to existing technologies, this invention features a smaller transmission stroke. The four-bar linkage enables vertical movement of the brewing head, with the handle's rotation driving the linkage's action. The capsule holder assembly is mounted on the brewing support in a drawer-like push-pull configuration, shortening the brewing head's opening and closing stroke and resulting in a more compact brewing mechanism. However, the problem is its complex structure and inability to quickly reset. Utility Model Content
