Abstract:
1. An extraction device for an immersion beverage primary liquid, mainly comprising: a filtration stand comprising an upper section disposed with a circular opening frame and a lower section disposed with a plurality of folded-type bars separatively mounted to the circular opening frame to form a cup-shaped frame with a hollowed circumferential surface and a hollowed bottom surface, the filtration stand being vertically downwardly entered and engaged in or being upwardly rejected from a liquid-collecting cup, wherein a plurality of outwardly-faced positioning convex points being arranged at same horizontal level are respectively provided on top sections of the circumferentially-arranged folded-type bars; an elastic fixing ring being formed of non-closed-ended type, comprising a ring body formed with an elastic ring opening and capable of being bottom-up fitted to and elastically engaged and fastened outside a top section of the filtration stand, so that, when extending the elastic fixing ring to upwardly pass through the positioning convex points of the circumferentially-arranged folded-type bars located at the top section of the filtration stand, the elastic fixing ring can be elastically rebounded to position above the positioning convex points of the circumferentially-arranged folded-type bars to stop the elastic fixing ring from being downwardly slid; and a filter made of a thin material provided with high-density meshes and shaped as a cup type formed by cutting and sewing or folding to be configured to adaptively engage outside the filtration stand in loose-fit, comprising a top section outwardly clamped by the elastic fixing ring to be positioned and clamped outside the filtration stand; characterized in that a cup-shaped filter stand formed herewith is capable of vertically being downwardly engaged in the liquid-collecting cup, installing food material such as coffee powder or tea leaves therein and receiving an adequate hot water to be received in the liquid-collecting cup, and the filtration stand is lifted to be positioned or stayed at or above a cup opening of the liquid-collecting cup, so that an extracted primary liquid passing through the filtration stand and the filter is directly dripped into the liquid-collecting cup for rapid filtration and concentration and a separated and filtered residue is collected in the filter.
