Description

Technical Field

[0001] The present invention relates to the technical field related to juice extraction, and in particular to a juicer. Background Art

[0002] Existing juicers include a juicing cup, a rotating auger mounted within the cup, and a motor that drives the auger. The upper sidewall of the juicing cup is equipped with an inlet for feeding the juicing material (fruit or vegetables). The auger's cutting section, in conjunction with the inner wall of the juicing cup, crushes the juicing material. The auger's grinding section then separates the juice from the residue. When squeezing large chunks of juicing material, if not pre-cut into smaller pieces, the material can easily become stuck. When squeezing long strips of juicing material (such as sugarcane), the material can easily become entangled in the auger's cutting section, affecting juicing efficiency. Summary of the Invention

[0003] In order to overcome the existing technical defects, the purpose of the present invention is to provide a juicer to solve the above technical problems.

[0004] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0005] The juicer is equipped with a rotary blade support, which is provided with a plurality of first juice outlet holes, and a plurality of second juice outlet holes are provided on the rotary blade support.

[0006] By adopting the above technical solution, when the driving unit is started, the screw propeller is driven to rotate, the rotation of the screw propeller drives the outer teeth to rotate, the rotation of the outer teeth drives the gear to rotate, the rotation of the gear drives the inner teeth to rotate and the rotating knife frame is linked to rotate, and the rotation of the rotating knife frame drives the cutter to rotate. When the juice material for juicing is put into the feed port, the juice material can be cut by the rotating cutter, and the long strip juice material can be cut into small sections, and the large block juice material can be cut into small slices. The cut juice material falls from the drop port into the rotating knife frame and falls onto the screw propeller. When the screw propeller rotates to spin the juice material, the juice material can be received by the receiving part, and the screw propeller cooperates with the inner side wall of the receiving part to spin and crush the juice material for the first time. Juicing, when the crushed juice material is transported to the extrusion chamber, the right end of the spiral propeller cooperates with the spinning chamber to squeeze the juice material for secondary juicing. The squeezed juice falls through the first juice outlet and is output from the juice outlet, and the juicy residue is discharged from the residue outlet; when using the juicer of this scheme to squeeze juice, the juice material will be cut into small segments or slices by the cutter on the rotating blade holder before contacting the spiral propeller, avoiding the phenomenon of large pieces of juice material being stuck when juicing and the long pieces of juice material being entangled with the spiral propeller when juicing, affecting the juicing effect, which can improve the efficiency of juicing and avoid consumers from cutting large pieces of juice material into small pieces in advance, thereby improving the user experience; in addition, the rotating blade holder is arranged in the juice cup to reduce the volume of the whole machine, which can realize the miniaturization of the juicer.

[0007] In order to better solve the above technical defects, the present invention also has a better technical solution:

[0008] In some embodiments, the juice cup includes a cup body, a feed barrel on the upper part of the cup body, and an end shell detachably connected to the cup body, the feed port is arranged at the top of the feed barrel, the juice outlet is arranged at the lower part of the cup body, an extrusion shell is arranged in the end shell, the extrusion cavity is arranged in the extrusion shell, a plurality of second juice outlet holes are arranged on the extrusion shell, and the slag outlet is located at the right end of the end shell and is connected to the extrusion cavity in the extrusion shell.

[0009] In some embodiments, the feed barrel has a raised portion on its front side, with a concave cavity formed within the raised portion, communicating with the interior of the feed barrel and the interior of the cup body. The right end of the receiving member is connected to the end shell, and the lower portion of the cavity formed between the end shell body and the extrusion shell communicates with the lower space within the shell body. When the juicing material is cut within the feed barrel, large chunks of juicing material will be driven by the cutter to become lodged in the concave cavity, thereby securing them and facilitating smooth cutting. This prevents jitter or rotation of the large chunks of juicing material during cutting, which could affect the cutting process.

[0010] In some embodiments, the receiving member is mounted with a first filter element that blocks the first juice outlet, and three gears are evenly distributed around the circumference. The first filter element allows for filtration of the juice, and the evenly distributed three gears achieve a better drive effect, making the drive structure more stable and reliable.
