Juicer and juice extraction screw thereof

A juicer comprising:

• a housing having a top and including a juice spout on a periphery surface, and a support on a bottom;
• a filtering mechanism disposed in the housing including a cylindrical wall having a meshed screen portion;
• a cylindrical feed chute disposed on and engaging the top of the housing,
• a rotating mechanism disposed in the filtering mechanism, the rotating mechanism including a screw comprising helical screw blade formed on an outer surface and extending helically upward and tapering to form a top free end, a bottom of the rotating mechanism being coupled to an electric motor and rotatable about a rotating axis of the electric motor, wherein the top free end of the screw is located at an eccentric position relative to the rotating axis and at an uppermost vertical point relative to the remainder of the screw, wherein the cylindrical feed chute is coaxially aligned with the screw with respect to the rotating axis, wherein a space is formed between the filtering mechanism and the screw that can accommodate produce having a width greater than a radius of the helical screw blade passing through the feed chute.
