A juicer comprises a base part, a juicer body, a strainer, a threaded cutter and a feed inlet, wherein the strainer is arranged within the juicer body, the juicer body is covered over with the feed inlet and a squeezing chamber is formed between the feed inlet and the strainer, and a buffer chamber is formed between the upper portion of the threaded cutter and the lower portion of the feed inlet; a pivot joint is arranged at the top of the screw body and is pivotally connected to the inner surface of the lower portion of the feed inlet, and the upper portion of the screw body from bottom to top is tapered at first and then broadened to form a radial projecting top. The juicer has increased squeezing efficiency and juice yield, and avoids accumulation of squeezed food.

A juice extraction device for extracting juice from food includes a hollow juice extraction screw capable of being rotated along an axis and having a food inlet through which food enters the juice extraction device; a mesh filter for separating the juice from the food, the mesh filter encompassing the juice extraction screw; and a housing encompassing the mesh filter. The provision of a hollow juice extraction screw can minimize the length of the device while maintaining juicing efficiency. This feature also allows the device to be placed vertically, such that various components, including the juice exit, may be located at the bottom position for improved efficiency and convenience.

A juicer includes a housing being open to top and including an annular first flange on a top and at least one lower juice spout on a peripheral surface, and a support on a bottom; a filtering mechanism in the housing and including longitudinal ridges on an inner surface, screens each disposed between two adjacent ones of the ridges, annular second flanges on an outer surface, a first rim extending downward from the lowest second flange, and at least one port through the first rim; a rotating mechanism in the filtering mechanism and including an annular element on a bottom edge, a helical screw blade on an outer surface, and an electric motor for rotating the screw blade; and a feed chute on the housing and including an annular member on a bottom edge and a second rim extending downward from the annular member.

An oil extractor that includes: a main body housing; a motor; a feed hopper detachably coupled to the upper end of the main body housing to feed grain; a shell that communicates with the lower end of the feed hopper to receive the grain and is detachably coupled to one side of the main body housing; a screw shaft inserted into the shell and having an end portion that passes through one side of the main body housing and is coupled to the motor; a fastening means for detachably coupling the shell to the main body housing; and a shell cover surrounding the shell. The shell cover has a groove formed on its lower portion for receiving the shell and is supported by the main body housing and moves between a first position at which the shell is covered and a second position at which the shell is exposed.

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.

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.

The present invention relates to a juicer comprising a screw is arranged inside a net drum, and a rotary brush placed between an inner wall of a housing and an outer wall of the net drum, wherein a screw coupling protrusion or a screw coupling groove is formed on the upper part of the screw and a rotary brush coupling groove or a rotary brush coupling protrusion is formed on the upper part of the rotary brush such that the screw coupling protrusion and the rotary brush coupling groove are coupled or the screw coupling groove and the rotary brush coupling protrusion are coupled in such a manner that the rotary brush is directly rotated by the screw.

Disclosed are a separable screw and a juicer using the same. The separable screw according to the disclosure includes a first module including a cylindrical main body unit formed with a screw thread on an outer surface thereof and having an inner hollow space, and a plurality of slits formed along a circumference of the main body unit spaced apart from each other; and a second module including a cylindrical main body unit detachably coupled to the inner hollow space and formed with a plurality of ribs inserted in the slits, and a residue discharging guider placed below the main body unit as a ring shape and formed with protrusion protruding from an outer surface thereof in a radial direction and guiding residue to be discharged. Juice passes into the screw through a gap between the slit and the rib while the first module and the second module are coupled.

The present invention relates to a juice extractor. The juice extractor of the present invention includes: a main body; a housing; a cover; a rotary brush mounted between an inner wall surface of the housing and an outer wall surface of the mesh drum, the rotary brush including at least one brush; and a feed screw connected with the drive shaft of the main body and disposed inside the mesh drum, wherein the feed screw includes a plurality of retaining slots formed on a lower circumferential bottom surface thereof and the rotary brush includes a plurality of engagement parts formed on an inner circumferential surface of a lower end portion thereof, so that the engagement parts of the rotary brush are engaged with the retaining slots of the feed screw to cause the rotary brush to be rotated together with the rotation of the feed screw.

The technology relates to a juice squeezing module for a juicer including: a juice squeezing drum mounted on a body of the juicer in such a manner as to be open on the top surface thereof and an engagement gear disposed on the edge of the periphery of the bottom surface thereof; a cap adapted to cover the top surface of the juice squeezing drum; a juice squeezing screw rotatably mounted at the inside of the juice squeezing drum; a screen drum mounted at the inside of the juice squeezing drum; a rotating brush adapted to brush the juice squeezing drum and the screen drum and having a brush ring gear connected to the engagement gear; and brush rotating means disposed on the underside of the juice squeezing drum to transmit the driving force of a driving shaft of the body to the engagement gear to rotate the rotating brush.
