US 6,186,057 B1 · Automatic citrus juice squeezer

Abstract

The improvements to the automatic citrus juice squeezer consist of: a movement of the pressure cup (3) by means of a drive screw (5) and a guide column (6); the cup being removably-mounted and detachable from its holder (7) by raising a trip fastener (12) using a catch (13); it has five angularly equidistant blades (2); a squeezer-filter (16) and support assembly (1) can descend against the action of an axial spring (14), maintaining the dynamic connection with the drive shaft by means of gears (18) that may slide along an intermediate sprocket (19); the juice collector (17) empties into a dish (20) which opens/closes a tilting plug (21) as it is introduced/extracted: the blades (2) are connected to the fixed shaft (15) by elastic legs (23) with internal strengtheners (24) which fit into a peripheral neck (25) of the said shaft; and the cup's (3) profile has an enlarged lower curvature to prevent its separation from the squeezer support (1) from narrowing.
