The juice extraction module includes a crushing portion formed on a top end of the screw to be narrowed upward, the crushing portion having a crushing blade formed thereon; and a crushing processing portion connected to the input port and formed in a bottom of the lid to be concave for accommodating the crushing portion. ## Claims ### Claim 1 A juice extraction module for a juicer, which includes a container formed with a juice discharge port, a sieve positioned inside of the container, a screw positioned inside of the sieve to rotate about a central axis and extract juice from a material, and a lid coupled to a top end of the container and formed with an input port through which the material is input, the juice extraction module comprising: a crushing portion formed on a top end of the screw to be narrowed upward, the crushing portion having a crushing blade formed thereon; and a crushing processing portion connected to the input port and formed in a bottom of the lid to be concave for accommodating the crushing portion on the top end of the screw, an inner surface of the crushing processing portion including a crushing processing surface and a material guide surface, wherein the crushing processing surface is formed to be increasingly close to the crushing blade of the screw in a rotational direction in which the crushing blade rotates about the central axis during operation such that a first distance between the crushing processing surface and an outer edge of the crushing blade at a first location rotationally adjacent the input port is greater than a second distance between the crushing processing surface and the outer edge of the crushing blade at a second location rotationally adjacent the first location and such that the second distance between the crushing processing surface and the outer edge of the crushing blade at the second location is greater than a third distance between the crushing processing surface and the outer edge of the crushing blade at a third location rotationally adjacent the second location, wherein the material guide surface continues from the input port and is formed to be inclined toward the central axis, whereby the material guide surface guides the material so that a lateral side of the material begins to be crushed by the crushing blade, and wherein the crushing blade crushes the material in advance within the crushing processing portion formed in the bottom of the lid. ### Claim 2 (depends on 1) The juice extraction module according to claim 1, wherein the crushing blade is formed so that the material input through the input port is crushed while a lateral side of the material is pushed outwards, and the crushing processing portion is provided with an inner surface to hold the material pushed outwards by the crushing blade, whereby the material is crushed between the crushing blade and the inner surface of the crushing processing portion. ### Claim 3 (depends on 1, 2) The juice extraction module according to claim 1 or 2, wherein the crushing processing portion covers an entire bottom region of the input port at the height of the crushing processing portion connected to a bottom end of the input port. ### Claim 4 (depends on 1, 2) The juice extraction module according to claim 1 or 2, wherein a bottom region of the input port is positioned to be offset within a semicircle region of a circle having a diameter corresponding to a diameter of the crushing processing portion with a central shaft of the screw as a center. ### Claim 5 (depends on 1) The juice extraction module according to claim 1, wherein a bottom end of the material guide surface conforms to an inner surface of the sieve. ### Claim 6 (depends on 1) The juice extraction module according to claim 1, wherein the crushing portion of the screw extends to pass over a top end of the sieve and the crushing portion is accommodated in the crushing processing portion of the lid. ### Claim 7 A juice extraction module for a juicer, comprising: a container formed with a residue discharge port and a juice discharge port; a sieve positioned inside of the container; a screw positioned inside of the sieve to extract juice from a material, and a lid coupled to a top end of the container and formed with a input port through which the material is input, wherein a crushing portion is formed on a top end of the screw to be narrowed upward, the crushing portion having a crushing blade formed thereon, wherein the lid is formed with a crushing processing portion, the crushing processing portion being connected to the input port and accommodating the crushing portion, wherein the input port is disposed to be offset outwards from a central axis of the screw and has a width larger than the shortest distance from the central axis of the screw to an inner circumferential surface of a top end of the sieve, wherein the crushing processing portion is formed with a material guide surface for assisting guidance of the material from the input port to the sieve, wherein an inner surface of the crushing processing portion comprises a crushing processing surface that is formed to be increasingly close to the crushing blade of the screw in a rotational direction in which the crushing blade rotates about the central axis during operation such that a first distance between the crushing processing surface and an outer edge of the crushing blade at a first location rotationally adjacent the input port is greater than a second distance between the crushing processing surface and the outer edge of the crushing blade at a second location rotationally adjacent the first location and such that the second distance between the crushing processing surface and the outer edge of the crushing blade at the second location is greater than a third distance between the crushing processing surface and the outer edge of the crushing blade at a third location rotationally adjacent the second location, and wherein the material guide surface continues from the input port and is formed to be inclined toward the central axis of the screw, whereby the material guide surface guides the material so that a lateral side of the material begins to be crushed by the crushing blade. ### Claim 8 (depends on 7) The juice extraction module according to claim 7, wherein the crushing processing surface is formed with at least one milling blade. ### Claim 9 (depends on 1) The juice extraction module according to claim 1, wherein the crushing processing surface is formed with at least one milling blade. ### Claim 10 A juice extraction module for a juicer comprising: a container formed with a juice discharge port; a sieve positioned inside of the container; a screw positioned inside of the sieve to rotate about a central axis and extract juice from a material, the screw including a crushing portion formed at a top end thereof which includes a crushing blade formed thereon; and a lid coupled to a top end of the container and formed with an input port through which the material is input and formed with a crushing processing portion connected to the input port at a bottom of the lid, the crushing processing portion being concave to accommodate the crushing portion at the top end of the screw and having an inner surface that includes a crushing processing surface, wherein the crushing processing surface is formed to be increasingly close to the crushing blade of the screw in a rotational direction in which the crushing blade rotates about the central axis during operation such that a first distance between the crushing processing surface and an outer edge of the crushing blade at a first location rotationally adjacent the input port is greater than a second distance between the crushing processing surface and the outer edge of the crushing blade at a second location rotationally adjacent the first location and such that the second distance between the crushing processing surface and the outer edge of the crushing blade at the second location is greater than a third distance between the crushing processing surface and the outer diameter of the crushing blade at a third location rotationally adjacent the second location. ### Claim 11 (depends on 10) The juice extraction module according to claim 10, wherein the crushing processing portion further includes a material guide surface that continues from the input port and is formed to be inclined toward the central axis, whereby the material guide surface guides the material so that a lateral side of the material begins to be crushed by the crushing blade during operation.
