This invention relates to a coffee cup and a coffee-making method. The coffee cup includes a cup body, a
grinding chamber, a
clutch mechanism, and a drive mechanism. The cup body is fitted over the
grinding chamber. The drive mechanism is connected to the
clutch mechanism. A blade is installed inside the
grinding chamber and is connected to the
clutch mechanism. The clutch mechanism can be connected to or separated from the grinding chamber, allowing the grinding chamber to operate in both grinding and extraction states. In the grinding state, the clutch mechanism is separated from the grinding chamber, and the drive mechanism rotates the blade in a first direction. In the extraction state, the clutch mechanism is connected to the grinding chamber, and the drive mechanism rotates both the blade and the grinding chamber in a second direction. This coffee cup combines grinding and extraction functions, using
centrifugal force to extract coffee, resulting in a high extraction rate and better
coffee flavor. Furthermore, the nested arrangement of the cup body and grinding chamber, with the grinding chamber serving as both a grinding and extraction chamber, effectively saves space, making the overall coffee cup more compact, portable, and convenient to use.
