Description

Technical Field

[0001] This utility model relates to the field of juicer technology, specifically a screw assembly for a horizontal juicer and a horizontal juicer. Background Technology

[0002] As people increasingly pursue healthy eating, slow juicers, as a household appliance that can efficiently extract the essence of fruits and vegetables, are gradually being accepted and used by a wide range of consumers. Slow juicers utilize low-speed spiral extrusion technology to gently extract fresh juice from fruits and vegetables, preserving not only the rich nutrients and original flavor of the ingredients but also avoiding the destruction of nutrients caused by high temperatures and oxidation. Slow juicers have become an important tool for modern families pursuing a healthy lifestyle.

[0003] Existing juicers rely on the threads on the screw. By rotating the screw, fruits and vegetables that are close to the threads can be pushed into the filter screen for squeezing and juicing. However, when processing long or hard fruits and vegetables such as sugarcane, which are high in fiber, users need to cut the fruits and vegetables into small pieces before putting them into the juicer. This is not only cumbersome, but also seriously affects the overall user experience.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The existing juicers mentioned above use a rotating screw to push fruits and vegetables tightly attached to the screw threads into a filter screen for juicing. However, when processing longer or harder fruits and vegetables, such as sugarcane and other high-fiber fruits and vegetables, users need to cut them into small pieces before putting them into the juicer. This is not only cumbersome but also seriously affects the overall user experience. The technical solution adopted by this utility model to solve this problem is:

[0006] A screw assembly for a horizontal juicer includes a screw body, the screw body including a rotatable shaft, a threaded portion disposed on the shaft, and a cutting portion disposed on the shaft for cutting fruits and vegetables.

[0007] Furthermore, the rotating shaft is provided with a cutting thread, which extends spirally toward one end of the rotating shaft, and the cutting part includes a cutting blade located on the cutting thread.

[0008] Furthermore, the end of the cutting blade is inclinedly connected to the cutting thread to form a chamfer.

[0009] Furthermore, the cross-section of the cutting edge is triangular.

[0010] Furthermore, the threaded portion includes a first extrusion thread connected to the cutting thread, the first extrusion thread being obliquely connected to the cutting thread and the outer wall of the shaft to form a rounded corner.

[0011] Furthermore, the pitch of the cutting thread is greater than the pitch of the first extrusion thread.

[0012] Furthermore, the threaded portion also includes a second extrusion thread located at the end of the shaft, and the connection between the second extrusion thread and the first extrusion thread is inclined to form a rounded corner.

[0013] Furthermore, the length of the cutting edge is less than the length of the cutting thread.

[0014] Furthermore, the cutting blade is integrally formed on the cutting thread.

[0015] This utility model also provides a horizontal juicer, including a juicer housing and a screw assembly as described above for use in a horizontal juicer, disposed within the juicer housing. The juicer housing has an inner cavity and a feed inlet communicating with the inner cavity. The inner cavity has a filter mechanism for cooperating with the screw body. The position of the feed inlet corresponds to the cutting part.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention features a threaded section and a cutting section on a rotating shaft. When processing long or hard fruits and vegetables, the user rotates the shaft, and both the cutting and threaded sections rotate synchronously with it. The cutting section cuts the fruits and vegetables into small pieces, and the threaded section pushes these small pieces into the filter screen inside the juicer for juicing. This simplifies the operation process, eliminating the need for users to pre-cut the fruits and vegetables. It effectively solves the problem of existing juicers that require users to pre-cut long or hard fruits and vegetables, such as sugarcane, into small pieces before processing them, which is not only cumbersome but also significantly impacts the overall user experience.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 7 The screw assembly shown is used in a horizontal juicer and includes a screw body 5. The screw body 5 includes a rotatable shaft 51, a threaded portion 52 provided on the shaft 51, and a cutting portion provided on the shaft 51 for cutting fruits and vegetables.

[0028] This invention features a threaded section and a cutting section on a rotating shaft. When processing long or hard fruits and vegetables, the user rotates the shaft, and both the cutting and threaded sections rotate synchronously with it. The cutting section cuts the fruits and vegetables into small pieces, and the threaded section pushes these small pieces into the filter screen inside the juicer for juicing. This simplifies the operation process, eliminating the need for users to pre-cut the fruits and vegetables. It effectively solves the problem of existing juicers that require users to pre-cut long or hard fruits and vegetables, such as sugarcane, into small pieces before processing them, which is not only cumbersome but also significantly impacts the overall user experience.

[0029] Optionally, in some embodiments, a drive mechanism is connected to one end of the screw body 5, and the user manually rotates the drive mechanism to drive the rotating shaft 51 to rotate.

[0030] Optionally, in some embodiments, a drive mechanism is connected to one end of the screw body 5. The drive mechanism includes a drive motor. When the drive motor operates normally, it drives the rotating shaft 51 to rotate.

[0031] Optionally, in some embodiments, the cutting section includes cutting teeth located on the rotating shaft 51, the cutting teeth being gear-shaped.

[0032] Optionally, in some embodiments, the cutting section includes cutting spikes located on the rotating shaft 51, the cutting spikes being elongated.

[0033] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the cutting part includes a cutting blade 53 located on the cutting thread 521.

[0034] Furthermore, the rotating shaft 51 and the threaded part 52 are integrally formed. The integral forming design has no splicing or welding seams, which makes the overall structure more robust and better able to withstand the stress of fruit and vegetable squeezing and cutting, effectively extending the service life of the equipment and helping to reduce failures caused by structural damage or wear.

[0035] like Figures 1 to 7 The rotating shaft 51 shown is provided with a cutting thread 521, which extends spirally toward one end of the rotating shaft 51. The cutting part includes a cutting blade 53 located on the cutting thread 521.

[0036] Furthermore, when users need to process long or hard fruits and vegetables such as sugarcane, the cutting edge 53 on the cutting thread 521 can directly contact the fruits and vegetables and cut them during the rotation of the rotating shaft 51, making the cutting process more direct and efficient.

[0037] Furthermore, the cutting thread 521 extends spirally toward one end of the rotating shaft 51, and the cutting blade 53 is located on the cutting thread 521, so that the cutting blade 53 can move along a continuous spiral path when cutting fruits and vegetables, which helps to ensure the uniformity and consistency of the cutting and improves the cutting efficiency.

[0038] Furthermore, the cut fruit and vegetable pieces can enter the filter mechanism 4 more smoothly under the push of the threaded part 52 for squeezing and juicing, which helps to reduce the problems of blockage and poor juicing caused by the fruit and vegetable pieces being too large or irregular in shape. Since the cutting blade 53 cuts the fruit and vegetables into small pieces, the juice of the fruit and vegetables can be squeezed out more easily, thereby increasing the juice yield.

[0039] Optionally, in some embodiments, the cutting blade 53 and the cutting thread 521 are detachably connected, and the cutting blade 53 and the cutting thread 521 can be connected by threaded connection, snap-fit ​​connection, slot connection or other connection methods.

[0040] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the cutting blade 53 and the cutting thread 521 are integrally formed.

[0041] like Figures 1 to 7 The end of the cutting blade 53 shown is inclinedly connected to the cutting thread 521 to form a chamfer;

[0042] Furthermore, the chamfered edges make the blade sharper and the cutting surface wider, enabling it to cut into fruits and vegetables more effectively. This reduces resistance during cutting and improves cutting efficiency. The cutting blade 53 can cut fruits and vegetables faster during rotation, which helps to accelerate the subsequent pressing process.

[0043] Furthermore, the chamfered edge setting helps to increase the force-bearing area of ​​the cutting blade 53, making the cutting process more stable. While the cutting blade 53 is cutting fruits and vegetables, the chamfered edge can also provide a certain support, which helps to reduce vibration and deviation during the cutting process and effectively ensures the uniformity and consistency of the cut.

[0044] Furthermore, due to the presence of the chamfered edges, fruits and vegetables are less likely to get stuck or tangled on the cutting edge when passing through the cutting blade 53, which helps them pass through the cutting process smoothly and continue to be pushed to the filtering mechanism, thus reducing operational interruptions and efficiency reductions caused by jamming.

[0045] like Figures 1 to 7 The cross-section of the cutting blade 53 shown is triangular;

[0046] Optionally, in some embodiments, the cutting blade 53 has a rectangular cross-section. The rectangular cross-section is designed so that the cutting blade 53 can better distribute stress when cutting fruits and vegetables, which helps to reduce wear caused by stress concentration and thus extend the service life of the cutting blade 53.

[0047] Optionally, in some embodiments, the cross-section of the cutting blade 53 is trapezoidal. The trapezoidal cross-section allows the cutting blade 53 to form a certain angle during the cutting process, which helps the cutting blade 53 to cut fruits and vegetables more smoothly and effectively reduce cutting resistance and friction.

[0048] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the cutting blade 53 has a triangular cross-section. The triangular cross-section of the cutting blade 53 provides a sharp tip, which makes the cutting force stronger during the cutting process, enabling faster cutting of fruits and vegetables, helping to reduce the force required during cutting, and effectively improving the overall cutting efficiency.

[0049] like Figures 1 to 7 The threaded portion 52 shown includes a first pressing thread 522 connected to the cutting thread 521, and the first pressing thread 522 is obliquely connected to the cutting thread 521 and the outer wall of the rotating shaft 51 to form a rounded corner;

[0050] Specifically, the first extrusion thread 522 is located on the outer wall of the rotating shaft 51 and is spirally extended.

[0051] Furthermore, the rounded corners help reduce the sharp edges of the threaded portion 52, which helps fruits and vegetables to be pushed in more smoothly, reducing the risk of blockage and jamming. Fruits and vegetables can transition more smoothly from the cutting thread 521 to the first extrusion thread 522, thereby improving overall flowability and efficiency.

[0052] Furthermore, since the first extrusion thread 522 is inclinedly connected to the outer wall of the rotating shaft 51 to form a rounded corner, it helps to increase the contact area between the first extrusion thread 522 and the fruits and vegetables, so that the fruits and vegetables are subjected to more uniform force during the extrusion process, effectively improving the crushing and pressing effect of the fruits and vegetables.

[0053] Furthermore, the rounded corners help reduce stress concentration points between components, which helps reduce local stress during operation and effectively extends the service life of the components. The transition between the first extrusion thread 522 and the cutting thread 521 is smoother, reducing breakage or wear caused by stress concentration.

[0054] like Figures 1 to 7 The pitch of the cutting thread 521 shown is greater than the pitch of the first extrusion thread 522;

[0055] Furthermore, the pitch of the threaded portion 52 gradually decreases toward the filter mechanism 4.

[0056] Furthermore, as the volume of fruits and vegetables gradually decreases during the pressing process, the smaller pitch of the first extrusion thread 522 allows for more precise processing of the remaining fruits and vegetables, helping to reduce blockages and jamming during the pressing process and effectively ensuring the continuity and smoothness of the pressing process.

[0057] Specifically, in the initial stage of pressing, the fruits and vegetables are plentiful and hard, so a large driving force and space are required. The larger pitch of the cutting thread 521 can effectively improve the conveying efficiency and cutting force. In the later stage of pressing, the fruit and vegetable portion gradually decreases. At this time, the smaller pitch of the first extrusion thread 522 can process the remaining fruits and vegetables more precisely.

[0058] like Figures 1 to 7 The threaded portion 52 shown also includes a second extrusion thread 523 located at the end of the rotating shaft 51, and the connection between the second extrusion thread 523 and the first extrusion thread 522 is inclined to form a rounded corner;

[0059] Furthermore, the rounded corners help reduce the sharp edges of the threaded portion 52, which helps fruits and vegetables to be pushed in more smoothly, reducing the risk of blockage and jamming. Fruits and vegetables can transition more smoothly from the first extrusion thread 522 to the second extrusion thread 523, thereby improving overall flowability and efficiency.

[0060] Furthermore, the second extrusion thread 523 is inclinedly connected to the outer wall of the rotating shaft 51 to form a rounded corner, which helps to increase the contact area between the second extrusion thread 523 and the fruits and vegetables, so that the fruits and vegetables are subjected to more uniform force during the extrusion process, effectively improving the crushing and pressing effect of the fruits and vegetables.

[0061] Furthermore, the rounded corners help reduce stress concentration points between components, which helps reduce local stress during operation and effectively extends the service life of the components. The transition between the first extrusion thread 522 and the second extrusion thread 523 is smoother, reducing breakage or wear caused by stress concentration.

[0062] Optionally, in some embodiments, the first extrusion thread 522 extends spirally along a first direction, and the second extrusion thread 523 extends spirally along a second direction. The first direction is perpendicular to the second direction, and the second extrusion thread 523 is an elongated protrusion located on the side near the second discharge port 7. Firstly, the spiral arrangement of the first extrusion thread 522 and the second extrusion thread 523 in different directions helps to increase the pressing force applied by the threaded portion 52 to the fruits and vegetables at different angles. This facilitates the extrusion and crushing of fruits and vegetables in multiple directions and angles, improving the pressing effect and effectively reducing the amount of fruit and vegetable waste. The juice remains in the residue; secondly, the spiral arrangement of the first extrusion thread 522 and the second extrusion thread 523 in different directions helps to break the blockage of fruits and vegetables during the transportation process, and can better cope with fruits and vegetables of different shapes and hardness, which helps to reduce the phenomenon of fruits and vegetables getting stuck in the transportation path; finally, the second extrusion thread 523, as a long strip protrusion, can increase the contact area between the fruits and vegetables and the second extrusion thread 523, thereby more effectively pushing the fruits and vegetables forward. At the same time, since the second extrusion thread 523 is located on the side close to the second discharge port 7, it can better guide the filter residue to be discharged, effectively reducing the risk of filter residue blockage.

[0063] like Figures 1 to 7 The length of the cutting edge 53 shown is less than the length of the cutting thread 521;

[0064] Furthermore, the longer cutting thread 521 can provide stronger structural support for the cutting edge 53. During the cutting process, the cutting edge 53 will be subjected to greater cutting force and impact force. The longer cutting thread 521 can better disperse these forces, which helps to reduce stress concentration and thus improve the mechanical strength and stability of the entire component.

[0065] Furthermore, although the cutting edge 53 is relatively short, a reasonable length setting can ensure that the cutting edge 53 maintains sufficient rigidity and stability during the cutting process, thereby improving cutting efficiency. The shorter cutting edge 53 can also reduce energy loss during the cutting process, making the cutting process more efficient.

[0066] Furthermore, the relatively short length of the cutting blade 53 helps to reduce manufacturing costs.

[0067] like Figures 1 to 7 The cutting blade 53 shown is integrally formed on the cutting thread 521;

[0068] Furthermore, the cutting blade 53 and the cutting thread 521 are integrally formed, which helps to eliminate the seam or connection point between the cutting blade 53 and the cutting thread 521, thereby greatly enhancing the overall structural strength and reducing the risk of breakage or damage caused by stress concentration, making the component more durable.

[0069] Furthermore, the one-piece molding design helps reduce the number of assembly steps for parts, eliminates the need for separate installation of the cutting blade 53, simplifies the production process, effectively improves production efficiency, and reduces manufacturing costs.

[0070] like Figures 1 to 7 The horizontal juicer shown includes a juicer housing 1 and a screw assembly for use in a horizontal juicer as described above, disposed within the juicer housing 1. The juicer housing 1 has an inner cavity 2 and a feed inlet 3 communicating with the inner cavity 2. The inner cavity 2 has a filter mechanism 4 for cooperating with the screw body 5. The position of the feed inlet 3 corresponds to the cutting part.

[0071] Furthermore, the juicer housing 1 is also provided with a first discharge port 6 for collecting fruit and vegetable juice and a second discharge port 7 for collecting filter residue. The filter mechanism 4 is arranged around the screw body 5. The side wall of the filter mechanism 4 is provided with a filter hole 41 communicating with the first discharge port 6. A residue discharge gap 42 communicating with the second discharge port 7 is provided between the filter mechanism 4 and the screw body 5.

[0072] Furthermore, the first discharge port 6 is set in a vertical direction, and the second discharge port 7 is set in a horizontal direction.

[0073] Furthermore, the feed inlet 3 is located directly above the cutting section.

[0074] Specifically, the user feeds fruits and vegetables into the inner cavity 2 through the feed inlet 3, rotates the rotating shaft 51, and the threaded part 52 and the cutting blade 53 rotate synchronously with the rotating shaft 51. The cutting blade 53 cuts the fruits and vegetables into small pieces, and the rotating threaded part 52 pushes the small pieces of fruits and vegetables into the filter mechanism 4. The fruits and vegetables are squeezed and juiced by the inner wall of the filter mechanism 4. The filter mechanism 4 has filter holes 41 on its side wall. The fruit and vegetable juice is stored through the filter holes 41 and the first discharge port 6 for the user to use. The filter residue produced after squeezing and juicing enters the second discharge port 7 through the residue gap 42 and is finally discharged outside the juicer.

[0075] Furthermore, by setting independent first discharge port 6 and second discharge port 7, the fruit and vegetable juice and residue are effectively separated. After the fruit and vegetables are pressed by the screw body 5 and the inner wall of the filter mechanism 4, the fruit and vegetable juice flows out of the first discharge port 6 through the filter hole 41, while the residue is discharged to the second discharge port 7 through the residue gap 42, so that the separation of fruit and vegetable juice and residue is more thorough.

[0076] Furthermore, the filter mechanism 4 is arranged around the screw body 5 so that the fruits and vegetables can contact the inner wall of the filter mechanism 4 more evenly during the pressing process, which is conducive to improving the processing efficiency of fruits and vegetables and effectively reducing the loss of fruit and vegetable juice and fruit residue caused by uneven processing.

[0077] The implementation method of this embodiment is as follows:

[0078] A screw assembly for a horizontal juicer includes a screw body 5. The screw body 5 includes a rotatable shaft 51, a threaded portion 52 on the shaft 51, and a cutting portion on the shaft 51 for cutting fruits and vegetables. The threaded portion 52 includes a cutting thread 521, and the cutting portion includes a cutting blade 53 located on the cutting thread 521. When the user needs to process long or hard fruits and vegetables such as sugarcane, the shaft 51 is rotated, and the cutting blade 53 and the threaded portion 52 rotate synchronously with the shaft 51. The cutting blade 53 can cut the fruits and vegetables. The process involves cutting the fruit and vegetables into small pieces and pushing them into the filter mechanism 4 inside the juicer through the threaded part 52 for squeezing and juicing. This simplifies the operation process, eliminating the need for users to cut the fruit and vegetables into small pieces beforehand. It effectively solves the problem that existing juicers use a rotating screw to push the fruit and vegetables tightly attached to the thread into the filter screen for squeezing and juicing. However, when processing longer or harder fruits and vegetables such as sugarcane and other high-fiber fruits and vegetables, users need to cut the fruits and vegetables into small pieces before putting them into the juicer, which is not only cumbersome but also seriously affects the overall user experience.

[0079] A horizontal juicer includes a juicer housing 1 and a screw body 5 disposed within the juicer housing 1. The juicer housing 1 has an inner cavity 2 and a feed inlet 3 communicating with the inner cavity 2. The inner cavity 2 has a filter mechanism 4 for cooperating with the screw body 5. The juicer housing 1 also has a first discharge port 6 for collecting fruit and vegetable juice and a second discharge port 7 for collecting filter residue. The filter mechanism 4 is arranged around the screw body 5, and the side wall of the filter mechanism 4 has a filter hole 41 communicating with the first discharge port 6. A connection is provided between the filter mechanism 4 and the screw body 5, communicating with the second discharge port 7. With a residue gap 42, the user feeds fruits and vegetables into the inner cavity 2 through the feed inlet 3, rotates the rotating shaft 51, and the threaded part 52 and the cutting blade 53 rotate synchronously with the rotating shaft 51. The cutting blade 53 cuts the fruits and vegetables into small pieces, and the rotating threaded part 52 pushes the small pieces of fruits and vegetables into the filter mechanism 4. The fruits and vegetables are squeezed and juiced against the inner wall of the filter mechanism 4. The filter mechanism 4 has filter holes 41 on its side wall. The fruit and vegetable juice is stored through the filter holes 41 and the first discharge port 6 for the user to use. The residue produced after squeezing and juicing enters the second discharge port 7 through the residue gap 42 and is finally discharged outside the juicer.
