Abstract: A high-capacity juicing machine includes: a base (210); a first support (230) and a second support (250) which are provided on the base (210) and are spaced from each other in a longitudinal direction; a first juicing member (270) having a first support shaft (275) rotatably provided on the first support (230) and an outer hollow rotor (271) which is positioned between the first support (230) and the second support (250); a second juicing member (290) having a second support shaft (293) rotatably provided on the second support (250), and an inner rotor (291) which is eccentrically positioned inside the first juicing member (270), and which is coupled to the second support shaft (293) to rotate together with the second support shaft; a first driving member (240) for driving the first support shaft (275); and a second driving member (260) for driving the second support shaft (293).

Abstract: A juicer including: a driving part composed of a housing having a housing hollow part formed therein, and having a through-hole through which inner air is discharged at the position eccentric to one side in the width direction from the central portion formed on the bottom portion thereof, and a motor provided the housing hollow part by being surrounded by a motor housing; a juice part connected to the driving part to be driven to squeeze the juice; and a fastening part for detachably coupling the juice part to the driving part.

Abstract: A juicer having improved juicing performance, including: a housing in which a motor is built in; a screw housing detachably coupled to the housing; and a driving screw exposed to one side of the housing and received in the screw housing so as to rotate by being coupled to a driving shaft rotatably driven by the motor. The driving screw includes: a driving screw main body in which an installation groove opened toward the housing is formed; one or more piezoelectric element provided in the installation groove of the driving screw main body; and a contact terminal electrically connected to the piezoelectric element and electrically contacting a contact electrode provided in the housing.
