The improvement device of this creation coffee ice temperature extraction,Specifically include that one offer bottom side liquid droping port upper section dip tank,One top side is to be able to accept liquid droping port to just or being inserted in,And bottom end has the middle section extraction cylinder of drainage hole and one is bridged positioning by providing dip tank bottom section on the inside of upper Kuo Zhuan Lying shape apical margin,And interior collar extension bottom section provides extraction cylinder and protrudes into and passes through,And extraction cylinder top section peripheral flange is enabled to be inserted in the soft socket ring to form socket; Thus the positioning that bridges on the outside of the upper expansion shape Lying shape apical margin of socket ring is provided with unification top section pot mouth,It enables extraction cylinder stack shell that can protrude into store,And lower section kettle body space is then made of the liquid collecting pot that coffee liquid is collected; Thereby device,Via extraction one drainage cloth of cylinder cylinder bottom across putting,Ground coffee can be accepted to be packed into and be allowed to pile tubular stack layers upwards,The ice Wen Rongshui stacked above what in dip tank is enabled,Gradually dissolution,It drips downward into extraction cylinder,And by a piece of even water cloth being nested with above ground coffee stack layers,Ice temperature melt water is set to be unfolded and seep downward to fall via the dispersive vectoring of cloth body tissue,So enable ground coffee stack layers uniformly by wet,It is i.e. slow successively to pass through ground coffee stack layers in cylinder,The coffee liquid completed is extracted,It is acted on by the filter residue of drainage cloth,And it can be dropped into directly down and complete to collect in liquid collecting pot; Thus reach the simplicity and operational safety of hierarchical operations,And the saving materials benef
