Description

Technical Field

[0001] The utility model relates to the technical field of manual coffee brewing devices, and particularly to an up-driven manual coffee brewing device. Background Art

[0002] Manual coffee brewing, as a beverage that can fully showcase the original flavor and aroma of coffee beans, has gained wide popularity and acclaim globally.

[0003] Among existing manual coffee brewing utensils, although various designs have been dedicated to improving the brewing effect, there are still many deficiencies. For example, the traditional manual water injection method is difficult to ensure the stability and uniformity of water injection. It is prone to deviation of the water flow direction or uneven water injection due to human factors, which in turn affects the extraction effect and taste of coffee. In addition, although some automatic or semi-automatic brewing devices can solve the water injection problem to a certain extent, their water outlet methods are often limited to a single direction or trajectory, making it difficult to achieve uniform brewing of coffee powder in all directions, resulting in uneven coffee concentration and poor taste.

[0004] In order to further improve the brewing effect of manual coffee, those skilled in the art have continuously explored and innovated. Among them, the technical solution with the application number CN201510340239.8 proposed a rotating water outlet mechanism for a coffee utensil and a coffee utensil. Through the transmission of a motor, a worm, and a turbine, the water outlet pipe can rotate axially, thus forming a circular water outlet trajectory above the coffee pot. This design has improved the water injection uniformity to a certain extent and enhanced the brewing effect. However, this solution still has limitations, that is, its water outlet range is limited to a circular trajectory and cannot achieve uniform brewing of coffee powder in all directions. In practical applications, this water outlet method may result in insufficient extraction of some coffee powder, while the other part is bitter due to over-extraction, ultimately affecting the concentration and taste of the whole cup of coffee.
