Two sets of foot are symmetrically arranged at the lower end of the filter cylinder, a combined filter is arranged in the filter cylinder, and a blocking device is arranged at the upper end of the combined filter. The blocking device is fixed to the filter cylinder through a plurality of buckles; a container cup is placed in the cylinder so that the rectangular block and the rectangular card slot are completely matched, and then a filter basket is placed in the container cup, and liquid vegetables are poured in, and the port of the cylinder is blocked by the blocking device, and the filter is started.
