Description

Technical Field

[0001] The utility model relates to the technical field of imitation hand-poured coffee devices, in particular to a bottom-driven imitation hand-poured coffee device. Background Art

[0002] Pour-over coffee is universally loved worldwide for its pure taste. However, achieving a high-quality cup requires not only good coffee beans but also skilled brewing techniques. The pour-over process requires not only stable and moderate water infusion, with the water flowing perpendicular to the coffee grounds for full contact, but also strict control of extraction time to avoid over-extraction, resulting in a bitter taste and loss of flavor. Furthermore, water must be kept from running over the filter paper, disrupting the internal extraction temperature. Therefore, brewing a delicious cup of pour-over coffee is not an easy task for the average user.

[0003] To improve coffee brewing, the technical proposal with application number CN201510340239.8 discloses a rotating water outlet mechanism for a coffee maker and the coffee maker. The rotating water outlet mechanism primarily comprises a fixed base, a motor, a turbine, a worm, and a curved water outlet pipe. The motor, worm, and turbine sequentially drive the water outlet pipe to rotate axially, causing the outlet end of the water outlet pipe to rotate in a circular motion above the coffee pot. However, this water outlet method still has limitations: the brewing range is limited to a circular trajectory, making it impossible to achieve uniform brewing of coffee powder in all directions, resulting in uneven brewing concentration and poor taste.
