Abstract

The invention provides a screw extrusion-type juice extractor which comprises a juice collecting cup, a screw and a filter screen support. A residue collecting groove is formed in the bottom face of the juice collecting cup, the cross sectional area of the residue collecting groove is smaller than the bottom face area of the juice collecting cup, a residue discharging opening is formed in the lateral wall of the residue collecting groove, the screw is arranged in the juice collecting cup in the axial direction of the juice collecting cup, a residue scraping part is arranged at the lower end of the screw and located in the residue collecting groove, the screw is provided with a plurality of working sections, a plurality of spiral ribs are arranged on the outer surface of each working section, the filter screen support is in a taper-shaped tube shape, a plurality of convex ribs are arranged at the position, corresponding to each working section, of the inner surface of the filter screen support, gaps are reserved between each convex rib and the multiple spiral ribs of the working section corresponding to the convex rib, the gaps are larger than or equal to 0.1 mm and smaller than or equal to 1 mm, and each convex rib is divided into two sections or multiple sections. The screw extrusion-type juice extractor has the advantages of being smooth in residue outlet, easy to wash, high in juice outlet rate and the like.

Description

technical field [0001] The invention relates to the field of household electrical appliances, and more specifically, relates to a screw extruding juice extractor.

Problems solved by technology

[0004] Currently used slow juicer or original juicer, the surface of the screw rod has several spiral ribs with continuous transition, and the inner surface of the filter frame is provided with several convex ribs with continuous transition on the surface. The effect has a great influence. If the ribs on the inner surface of the filter frame protrude too much from the filter frame, after squeezing the fruits and vegetables, the pomace will stay between the ribs and the wall of the filter screen, while the lower end of the inner surface of the filter frame will The protruding ribs of the filter frame are too few, resulting in insufficient space for the pomace to push down, making it difficult to press down the pomace, resulting in more pomace remaining in the filter frame, making it difficult to clean the juicer After continuous juicing for a long time, it will affect the juicing effect
