The safety cover includes a first cover portion erected to open the main input opening in the first position and closing the main input opening in the second position; and a second cover portion formed integrally with the first cover portion, the second cover portion moving the safety cover to the second position when the second cover portion is pushed by a downward applied force from the first position, whereby the first cover portion blocks the main input opening. ## Claims ### Claim 1 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 extract juice from a material; a lid coupled to a top end of the container and formed with an input portion through which the material is input; and a safety cover rotatably installed to a main input opening of a top end of the input portion to be movable between a first position and a second position, wherein the safety cover comprises a first cover portion erected to open the main input opening in the first position and closing the main input opening in the second position; and a second cover portion formed integrally with the first cover portion, the second cover portion moving the safety cover to the second position when the second cover portion is pushed by a downward applied force from the first position, whereby the first cover portion blocks the main input opening. ### Claim 2 (depends on 1) The juice extraction module according to claim 1, wherein the safety cover is connected by a hinge to both sides of the main input opening at both sides of a position in which the first cover portion and the second cover portion cross each other. ### Claim 3 (depends on 1) The juice extraction module according to claim 1, further comprising a bias means installed to the hinge so that the safety cover is biased to the first position, wherein the hinge is connected to a both sides of the main input opening at a position in which the first cover portion and the second cover portion are connected to each other. ### Claim 4 (depends on 3) The juice extraction module according to claim 3, wherein the bias means includes a torsion spring or weight. ### Claim 5 (depends on 1) The juice extraction module according to claim 1, further comprising a locking unit for locking the safety cover at the second position, wherein the locking unit comprises a knob positioned on an upper surface of the first cover portion and a locking piece positioned on a lower surface of the first cover portion and connected to the knob by an connection portion penetrating the first cover portion, the locking unit having a locking groove formed in the inner surface of the input portion so that the locking piece rotated by the knob is inserted into the locking groove. ### Claim 6 (depends on 1) The juice extraction module according to claim 1, wherein the input portion further comprises a secondary input opening formed in the top end thereof, the secondary input opening having a size smaller than the main input opening. ### Claim 7 (depends on 1) The juice extraction module according to claim 1, wherein the safety cover has a third position to which the safety cover is further rotated after passing the second position, and the first cover portion and the second cover portion at least partially cover the main input opening and the secondary input opening in the third position, respectively, wherein the secondary input opening have a size smaller than the main input opening is formed in the top end of the input portion. ### Claim 8 (depends on 1, 2, 3, 4, 5, 6, 7) The juice extraction module according to any one of claims 1 to 7, further 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 portion and formed in a bottom of the lid to be concave for accommodating the crushing portion, wherein the crushing blade crushes the material in advance within the crushing processing portion. ### Claim 9 (depends on 8) The juice extraction module according to claim 8, wherein the crushing blade is formed so that the material input through the input portion 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 10 (depends on 8) The juice extraction module according to claim 8, wherein the crushing processing portion covers an entire bottom region of the input portion at the height of the crushing processing portion connected to a bottom end of the input portion. ### Claim 11 (depends on 10) The juice extraction module according to claim 10, wherein a bottom region of the input portion 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 12 (depends on 10) The juice extraction module according to claim 10, wherein the inner surface of the crushing processing portion comprises a crushing processing surface formed to be gradually close to the crushing blade in a direction in which the crushing blade runs from the input portion. ### Claim 13 (depends on 10) The juice extraction module according to claim 10, wherein the inner surface of the crushing processing portion comprises a material guide surface continuing from the input portion and formed to be inclined toward a central axis of the crushing portion, whereby the material guide surface guides the material so that a lateral side of the material begins to be milled by the crushing blade. ### Claim 14 (depends on 13) The juice extraction module according to claim 13, wherein a bottom end of the material guide surface conforms to an inner surface of the sieve. ### Claim 15 (depends on 8) The juice extraction module according to claim 8, wherein the inner surface of the crushing processing portion comprises a crushing processing surface formed to be gradually close to the crushing blade in a direction in which the crushing blade runs from the input portion, and a material guide surface continuing from the input portion and formed to be inclined toward a central axis of the crushing portion to cause a lateral side of the material to begin to be milled by the crushing blade. ### Claim 16 (depends on 8) The juice extraction module according to claim 8, wherein the crushing portion extends to pass over a top end of the sieve and is accommodated in the crushing processing portion. ### Claim 17 (depends on 8) The juice extraction module according to claim 8, wherein the crushing processing portion comprises a crushing processing surface, and the crushing processing surface is formed with at least one milling blade. ### Claim 18 (depends on 1) The juice extraction module according to claim 1, wherein the input portion defines a โ€œโ€ shaped material input path. ### Claim 19 A safety cover rotatably installed to a main input opening of a mixer or juicer to move between a first position and a second position, the safety cover comprising: a first cover portion erected to open the main input opening in the first position and closing the main input opening in the second position; and a second cover portion moving the first cover portion to the second position, in which the first cover portion blocks the main input opening, when the second cover portion is pushed by a downward applied force from the first position.
