1. A juice extractor comprising:
a juice extractor base including upper and lower portions spaced in a vertical direction, with a concave surface formed on the upper portion of the juice extractor base and including a front end, a rear end spaced from the front end in a first horizontal direction perpendicular to the vertical direction, and a middle section intermediate the front and rear ends, with a height of the middle section of the concave surface in the vertical direction being smaller than that of the front end of the concave surface; a rotating shaft rotatably installed above the concave surface of the juice extractor base and extending in a second horizontal direction perpendicular to the first horizontal and vertical directions; and a juice squeezing wheel including a shaft hole, with the rotating shaft extending through the shaft hole to rotate with the juice squeezing wheel, with the juice squeezing wheel further including first and second ends extending in the second horizontal direction and spaced in a circumferential direction, with the juice squeezing wheel further including an outer surface extending between the first end and the second end, with an opening defined between the first and second ends of the juice squeezing wheel and through the juice squeezing wheel in the second horizontal direction, with a tapered distal portion extending contiguously with the outer surface from the second end towards but spaced from the first end of the juice squeezing wheel and within the opening, with the tapered distal portion having a decreasing radial thickness from the shaft hole with increasing distance from the second end of the juice squeezing wheel, with a crushing space defined between the outer surface of the juice squeezing wheel and the middle section of the concave surface of the juice extractor base for receiving a fruit which needs to be squeezed, and with the fruit in the crushing space crushed by the juice squeezing wheel to produce fruit juice when the rotating shaft rotates. |
