The elastic filter disc 11 is made of an elastic material, such as silica gel. During the extraction process, the coffee liquid above the elastic filter disc 11 is quickly sprayed out from the filter holes 111 under pressure and then collides with the coffee liquid in the extraction tank 21 or the wall part of the extraction tank 21 to be dispersed, so that the components in the coffee liquid are dispersed more uniformly, and secondary pressure extraction is realized.
