The utility model discloses a portable coffee filter cup structure and an Italian coffee
machine thereof, and belongs to the technical field of coffee equipment, the portable coffee filter cup structure comprises a cup body with a filter cavity, a
powder ejecting
assembly is arranged in the filter cavity, and the
powder ejecting
assembly comprises a movable top plate and a supporting column arranged at the lower end of the movable top plate; the device further comprises an elastic element which is arranged on the supporting column in a sleeving mode. Through the synergistic effect of the movable top plate and the elastic element, self-adaptive adjustment of the
stroke of the
brewing net is achieved, the problem that
powder is splashed when the powder amount is too small or blocked when the powder amount is too large is effectively solved, and extraction uniformity and stability are remarkably improved. Meanwhile, a mixing and filtering space is arranged, so that coffee liquid is roughly filtered, then secondarily mixed and finely filtered, full contact of
grease and micro powder is promoted, and the purity and taste mellowness of the liquid are enhanced. In addition, after
brewing is completed, the elastic element drives the movable top plate to automatically reset, the linkage structure promotes the powder residues to be rapidly separated from the inner wall of the filter cavity, and the powder residues are convenient to clean.
