Abstract
A coffee maker includes a water storage device having a water tank and a water outlet piping communicating with the water tank; a driving device having a driving motor and a driving shaft; and a swing device having a rotating mechanism mounted on the driving shaft and a shifting mechanism connected to the water outlet piping and moving along with the rotating mechanism when the latter rotates. The water outlet piping is brought by a horizontal rotational movement of the rotating mechanism and a linear movement of the shifting mechanism to swing and shift in a spiral rotational course from a center point to outer and inner areas of a filter in a reciprocating motion while pouring water at controlled volume and stability, enabling ground coffee beans on the filter to be quickly and evenly extracted by water to release aromatic smell and sweet flavor just like drip brewing manually.
