Description

Technical Field

[0001] This utility model relates to the technical field of juicers, and in particular to a juicing component for a juicer. Background Technology

[0002] Fruits and vegetables are the main sources of vitamins for the human body. Studies have shown that people who regularly eat fruits and vegetables are healthier than those who don't, especially in disease prevention. Fruits and vegetables play an irreplaceable role in this regard, making them excellent choices for a healthy diet. While fruits and vegetables are rich in nutrients, many people don't like to eat them directly. Therefore, many families have juicers to address this health concern. A juicer is a machine that can quickly extract juice from fruits and vegetables; small ones are suitable for home use. However, the juicing screws in existing juicers cannot cut through high-fiber fruits and vegetables, such as celery, bitter melon, and corn. The high-fiber parts of these vegetables remain inside the juicing cup, affecting the screw's ability to extract juice and resulting in incomplete juicing. Furthermore, the high-fiber parts create significant resistance to the screw, further reducing juicing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a juicing component for a juicer that can cut off the high-fiber parts of fruits and vegetables, has high juicing efficiency, and high juice yield.

[0004] The purpose of this utility model is achieved as follows:

[0005] A juicing component for a juicer includes a filter cup and a juicing screw. The juicing screw is disposed inside the filter cup. An annular boss is provided on the inner side wall of the filter cup. The juicing screw has a corresponding surface to the annular boss. The annular boss and the corresponding surface are respectively provided with radially staggered lower cutting protrusions and upper cutting protrusions.

[0006] The present invention can be further improved in the following ways.

[0007] The juicing screw includes an upper screw and a lower screw arranged at opposite ends, with the upper screw and lower screw engaging in a driving relationship; the outer periphery of the bottom surface of the upper screw forms the opposing surface.

[0008] The upper and lower screws are connected separately and located on the upper and lower sides of the annular boss, respectively. This invention's separate screw design for juicing facilitates disassembly and assembly, and also makes it easier to process the upper cutting protrusion.

[0009] The annular boss has at least one cutting groove distributed around the central axis of the juicing screw. The annular boss has two lower cutting protrusions, one inner and one outer, corresponding to the inner and outer sides of the cutting groove. A cutting groove is formed between the two lower cutting protrusions, and the cutting groove is distributed along the rotation trajectory of the upper cutting protrusion. The number of upper cutting protrusions is less than or equal to the number of cutting grooves. By setting multiple cutting grooves, the high-fiber parts of fruits and vegetables are cut off in a timely manner.

[0010] The protruding part of the upper cutting material is in the shape of an arc-shaped rib.

[0011] The upper surface of the annular boss is horizontal; or, the annular boss is funnel-shaped with the inner ring side lower and the outer ring side higher. The annular boss is tilted to facilitate the pulp and juice falling into the lower part of the juicing screw and continuing to be squeezed.

[0012] The bottom of the upper screw is provided with an upper screw thread, and the top of the lower screw is provided with a lower screw thread corresponding to the position of the upper screw thread. The lower screw thread is connected to the upper screw thread.

[0013] A pusher block is located at the bottom of the upper screw, corresponding to the annular boss. The width between the inner and outer ends of the pusher block is greater than the width between the inner and outer lower cutting protrusions corresponding to the cutting groove. The pusher block and the lower cutting protrusions are staggered vertically. The pusher block pushes the fruits and vegetables accumulated on the annular boss towards the inner ring side of the annular boss, causing them to fall into the lower section of the filter cup and the area of ​​the lower screw for further squeezing and juicing.

[0014] The side of the lower cutting protrusion facing the direction of the pusher block's movement transitions with the surface of the annular boss via an inclined or arc-shaped surface.

[0015] The upper periphery of the filter cup is provided with a surrounding plate, and the inner side of the surrounding plate forms a feeding port. The lower outer wall of the filter cup is provided with filter holes. An outer cup is also fitted around the lower section of the filter cup. The bottom of the outer cup is rotatably engaged with the lower end of the juicing screw. The lower side wall of the outer cup is also provided with a juice outlet and a residue outlet.

[0016] The outer cup and filter cup are detachably connected, as are the juicing screw and filter cup, making them easy to clean.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention uses the upper cutting protrusion on the juicing screw and the lower cutting protrusion in the juicing cup to cut the high-fiber part of the fruit and vegetable pulp. The cut high-fiber part reduces the resistance of the juicing screw, improves juicing efficiency, and makes it easier to extract the juice from the high-fiber part, thus increasing the juice yield.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1, as Figures 1 to 11 As shown, a juicer juicing assembly includes a filter cup 11 and a juicing screw 2. The juicing screw 2 is disposed inside the filter cup 11. The filter cup 11 has an annular boss 20 on its inner sidewall, and the juicing screw 2 has a corresponding surface 211 on the annular boss 20. The annular boss 20 and the corresponding surface 211 are respectively provided with radially staggered lower cutting protrusion 29 and upper cutting protrusion 24.

[0033] The juicing screw 2 includes an upper screw 21 and a lower screw 22 respectively arranged at the top and bottom, with the upper screw 21 and the lower screw 22 in a driving engagement; the outer periphery of the bottom surface of the upper screw 21 forms the opposing surface 211.

[0034] The upper screw 21 and the lower screw 22 are separately connected and located on the upper and lower sides of the annular boss 20, respectively. Specifically, the bottom of the upper screw 21 is provided with an upper buckle 26, and the top of the lower screw 22 is provided with a lower buckle 27 corresponding to the position of the upper buckle 26. The lower buckle 27 is screwed into the upper buckle 26, thereby achieving a fixed connection between the upper screw 21 and the lower screw 22. The upper buckle 26 is L-shaped. The diameter of the lower screw 22 and the diameter of the upper screw 21 are larger than the diameter of the annular boss 20. A mandrel 23 is provided inside the lower screw 22, and the lower end of the mandrel 23 extends out of the lower screw 22.

[0035] An annular boss 20 has at least one cutting groove 28 distributed around the central axis of the juicing screw 2. The annular boss 20 has two lower cutting protrusions 29 on the inner and outer sides corresponding to the cutting groove 28, and the cutting groove 28 is formed between the two lower cutting protrusions 29. The cutting groove 28 is distributed along the rotation trajectory of the upper cutting protrusion 24. The number of upper cutting protrusions 24 is less than or equal to the number of cutting grooves 28. The bottom surface of the upper cutting protrusion 24 is lower than the top of the cutting groove 28 (that is, the cutting groove 28 and the upper cutting protrusion 24 are in concave-convex fit).

[0036] The upper cutting protrusion 24 is in the shape of an arc-shaped rib.

[0037] In this embodiment, the cutting groove 28 has six grooves, and the upper cutting protrusion 24 has two grooves.

[0038] The upper surface of the annular boss 20 is horizontal.

[0039] A pusher block 25 is provided at the bottom of the upper screw 21 corresponding to the position of the annular boss 20. The width between the inner and outer ends of the pusher block 25 is greater than the width between the inner and outer lower cutting protrusions 29 corresponding to the cutting groove 28. The pusher block 25 and the lower cutting protrusions 29 are staggered vertically to avoid interference between the pusher block and the lower cutting protrusions when the upper screw rotates.

[0040] The side of the lower cutting protrusion 29 facing the direction of movement of the pusher block 25 transitions with the surface of the annular protrusion 20 on an inclined or arc-shaped surface. The inclined or arc-shaped transition plays a guiding role and avoids the pusher block 25 from colliding with it head-on.

[0041] The upper periphery of the filter cup 11 is provided with a surrounding plate 111, and a feeding port is formed on the inner side of the surrounding plate 111. The lower outer wall of the filter cup 11 is provided with filter holes 112. An outer cup 12 is also fitted around the lower section of the filter cup 11. The bottom of the outer cup 12 is rotatably engaged with the lower end of the juicing screw 2. The lower side wall of the outer cup 12 is also provided with a juice outlet 14 and a residue outlet 13. The lower end of the spindle 23 of the lower screw 22 extends beyond the bottom of the outer cup 12.

[0042] The juicer is also equipped with a base, which contains a drive motor. A clutch head is located on the top of the base, which is used to engage with the lower end of the spindle 23. The outer cup is connected to the top of the base, but is not shown in the figure.

[0043] When this invention starts working, the fruits and vegetables to be juiced are placed into the feeding port of the filter cup 11. The juicer drives the juicing screw 2 to rotate and extract juice. The upper screw 21 and the lower screw 22 rotate synchronously. The pulp is first squeezed by the upper screw 21. When the pulp contains tough plant fibers, the plant fibers are not easily broken. When they fall into the annular boss, they are easily cut by the upper cutting protrusion 24 in conjunction with the cutting groove 28. After being chopped, the plant fibers and the crushed pulp continue to flow downwards and are then squeezed by the lower screw 22. Because the plant fibers are cut, the resistance of the juicing screw 2 is reduced, and the juicing efficiency is improved. In addition, the juice inside the plant fibers is more easily squeezed out, increasing the juice yield.

[0044] Example 2 differs from Example 1 in that: Figure 12 As shown, the annular boss 20 is funnel-shaped with a lower inner ring side and a higher outer ring side.
