Abstract
An automatic juicer turns and pushes an upward facing juicing cone into a fruit for releasing juice. The juicer includes a base containing a motor, gear and shaft assembly. A fixed guide extends upward from the base and inner and outer shafts reside inside the fixed guide and are driven by the motor and gear assembly to rotate and advance the juicing cone into the fruit. The inner shaft includes threads to vertically advance and retreat a shaft nut and the outer shaft rotates with the inner shaft, but is lifted by the shaft nut when the inner shaft turns. The juicing cone releases the juice and a stationary bowl catches the juice.
Claims19
An automatic juicer comprising:
- a lid openable to allow fruit to be placed in the juicer;
- a base containing a motor;
- an inner shaft connected to the motor for rotating the inner shaft, the inner shaft having a fixed vertical position;
- an outer shaft rotatably coupled to the inner shaft to rotate with the inner shaft;
- a lifting nut threadably engaging the inner shaft and restrained from rotating and supporting the outer shaft to advance the outer shaft vertically when the inner shaft rotates;
- a bowl attached to the base;
- and
- a juicing cone above the bowl and attached to the outer shaft and rotating and advancing vertically with the outer shaft, the juicing cone rotating and pushing into a fruit for releasing juice from the fruit to be caught in the bowl.

An automatic juicer comprising:
- a lid openable to allow fruit to be placed in the juicer;
- a base containing a motor and gear assembly;
- an outer column fixed to the base and having a non-round interior and an inward reaching ceiling at the top of the outer column;
- an inner shaft connected to the motor and gear assembly for rotating the inner shaft, the inner shaft having a fixed vertical position;
- an outer shaft residing radially between the inner shaft and the outer column and having a footing reaching outward at the bottom of the outer shaft;
- a lifting nut residing under the outer shaft and threadably engaging the inner shaft and having a non-round exterior cooperating with the non-round interior of the outer column to restrict rotation of the lifting nut, the lifting nut to advance the outer shaft vertically when the inner shaft rotates;
- a guide fixed to the top of the inner shaft and rotatably coupled to the outer shaft to cause the outer shaft to rotate at the same speed as the inner shaft;
- a spring residing between the outer shaft and the outer column and under the outer column ceiling and over the outer shaft footing to urge the outer shaft downward;
- a bowl attached to the base;
- and
- a juicing cone above the bowl and attached to the outer shaft and rotating and advancing vertically with the outer shaft, the juicing cone rotating and pushing into a fruit for releasing juice from the fruit to be caught in the bowl.
