A coffee brewing mechanism includes a brewing module having a swing arm, a pot and a driving assembly. The pot is connected to the swing arm and is operable to swing back and forth between an ascending position and a press-down position. The driver assembly includes a link rod and a driving member, wherein one end of the link rod is connected to the swing arm and the other end is provided with a follower. A cam is connected to the driving member, has a working curve and is in rolling contact with the follower. The working curve is formed by connecting a first arc and a second arc, and a radius of curvature of the first arc is greater than a radius of curvature of the second arc.

A dual-purpose coffee filter hanging structure, comprising a filter bag and a hanging ear device separately provided on both sides of the filter bag. A fixing portion is provided in the hanging ear device; the fixing portion extends upwards to form a connecting section, the end of the connecting section extending upwards is provided with an inner ring section; an inner engaging groove is formed on the inner ring section adjacent to the connecting section; an outer ring section is provide on the outer side of the inner ring section; a first outer engaging groove is formed on each of two sides of the outer ring section; two inner engaging grooves and two first outer engaging grooves are provided opposite to each other in pairs in the vertical direction; both the inner engaging grooves and the first outer engaging grooves can be used to hang on the rim of a cup; and therefore, according to different requirements, the filter bag can be hung upright or obliquely on the cup to extract coffee.
