A juicer is disclosed. The juicer includes: a juice-extraction drum crushing and squeezing a juicing target and receiving a screw therein; a hopper coupled to the juice-extraction drum to define a predetermined space receiving the juicing target therein, and comprising an inner protrusion protruding from an inner surface of the hopper toward a central axis of the hopper; and a blade coupled to the hopper to be rotated about the central axis of the hopper and cutting the juicing target before the juicing target reaches the screw, wherein the blade includes: a lower blade rotated in a state of closely contacting a bottom surface of the hopper; and an upper blade bent to cover the inner protrusion of the hopper from above, wherein the upper blade crushes the juicing target in cooperation with the inner protrusion of the hopper.

Various juicing devices, systems, and methods are disclosed. The juicing device has mechanical squeezers, combination blades, front trays, and/or control systems for effective pressing.

A citrus juicer is set forth including a deformable container forming an extracting chamber to receive at least one portion of citrus fruit, and having an opening for introducing the citrus fruit; a frame forming a socket to receive the deformable container; a dividing ridge having a cross-section with a tip oriented towards the extracting chamber, and the dividing ridge being arranged to divide the citrus fruit when the citrus fruit is pressed against the tip thereof; a pressing system to exert pressure on the extracting chamber and against the socket. A method for extracting juice from citrus fruit is also disclosed.

A juicer insert for inserting into a preparation vessel, which juicer insert includes at least one rotatable tool holder, including at least one adapter element and at least one juicer tool. The transmission of rotational force the adapter element is configured at least indirectly couplable with the tool holder. The juicer tool is connected to the adapter element, so that a rotation of the adapter element causes a rotation of the juicer tool.

A juicer and blender-compatible power device, comprising: a driving part used for generating power; a first driving shaf and a second driving shaft, wherein the first driving shaft rotates by means of the driving part, the second driving shaft is a hollow shaft, the first driving shaft penetrates the inside of the second driving shaft, and the second driving shaft rotates at a speed different from that of the first driving shaft; a supporting part, wherein end parts of the the first driving shaft and the second driving shaft protrude from a hole of the supporting part, and the second driving shaft may be rotatably supported on the supporting part; a first bearing arranged between the first driving shaft and the second driving shaft; and a second bearing arranged between the second driving shaft and the supporting part. The first bearing and the second bearing are arranged to overlap in the horizontal direction. In the juicer and blender-compatible power device, the rotating shafts that rotate at high and low speeds may be formed into a dual-shaft form, so that same may be compatibly used for a juicer and a blender, and the power device may be made more compact.
