Description

[Technical Field]

[0001] This utility model relates to the field of household appliance technology, specifically a pomegranate pressing mechanism and a juicing device using the mechanism. [Background Technology]

[0002] As people's concept of healthy living continues to deepen, juicing equipment, as a convenient tool for extracting nutrients from fruits and vegetables, has become a common appliance in modern family kitchens. Currently, there are many types of juicers on the market with different structures, but their basic structure and working principle have commonalities.

[0003] Most juicers consist of four main parts: the main unit, the juice tray, the juicing head, and the top cover. The main unit serves as the power source for the entire device and contains a geared motor. The motor transmits power to the juicing head via a lifting shaft. The juicing head moves up and down and rotates simultaneously within the juice tray, squeezing the fruits and vegetables placed in the juice cup. The top cover sits on top of the juice tray, serving to both secure the fruits and vegetables and press them downwards to complement the rotating and squeezing action of the juicing head, thereby achieving the purpose of extracting juice from the fruits and vegetables.

[0004] Traditional juicers typically have multiple ridges around their circumference in the juicing head. The main function of these ridges is to physically squeeze the juice from the fruits and vegetables as the juicing head rotates.

[0005] However, this design has some shortcomings in actual operation, especially for fruits containing multiple small granules (such as pomegranates, oranges, etc.). The existing convex ridges often scrape off some granules during the rotation and squeezing process. When the granules are scraped off, they are not completely squeezed by the juicing head. Therefore, some juice and nutrients are not effectively extracted. This not only leads to the loss of juice, thus reducing juicing efficiency, but may also have an adverse effect on the taste and nutritional value of the final product.

[0006] This utility model was proposed in response to the shortcomings of the existing technology. [Utility Model Content]

[0007] The protrusions on the juicing heads of existing juicers mentioned above often scrape off some fruit particles during rotation and squeezing, resulting in fruit particles not being fully squeezed by the juicing head, leading to juice loss and reduced juicing efficiency.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A pomegranate juicing mechanism includes a juice receiving tray, a top cover, and a juicing disc structure. The top cover is located above the juice receiving tray. The juicing disc structure includes a juicing head and a drive connection part fixedly connected to the juicing head. The juicing head is located between the juice receiving tray and the top cover. The juicing head has multiple juicing protrusions spaced apart from top to bottom, and each of the juicing protrusions is arranged in a ring on the juicing head. The drive connection part can be connected to a drive source. When the drive source is working, the drive connection part can move up and down and rotate to drive the juicing head to move up and down and rotate within the juice receiving tray. The juicing protrusions support the pomegranates and squeeze the fruit located between the juicing head and the top cover to achieve juicing.

[0010] In the pomegranate pressing mechanism described above, each of the pressing protrusions is provided with at least one juice guiding notch.

[0011] In the pomegranate pressing mechanism described above, there are multiple juice guiding notches, and the multiple juice guiding notches are arranged circumferentially at intervals along the corresponding pressing protrusion assembly. The pressing protrusion assembly includes multiple arc-shaped protrusions arranged circumferentially at intervals along the pressing head, and each juice guiding notch is located between two arc-shaped protrusions.

[0012] In the pomegranate pressing mechanism described above, each of the pressing protrusion components has a corresponding juice guide notch.

[0013] In the pomegranate pressing mechanism described above, each of the pressing protrusions has a downwardly recessed pressing groove on its top.

[0014] As described above, the pomegranate pressing mechanism further includes a slag receiving tray connected to the pressing head. The slag receiving tray is located below the pressing head and has multiple drainage holes through which juice can flow into the slag receiving tray.

[0015] As described above, in a pomegranate pressing mechanism, the slag receiving plate is provided with a clearance hole for the output end of the drive source to be connected to the drive connection part for transmission, and a connecting component is provided between the slag receiving plate and the drive connection part to enable the two to be rotatably connected.

[0016] As described above, in a pomegranate pressing mechanism, a pressing plate is fixedly provided on the side of the pressing head. The free end of the pressing plate is arc-shaped, and there is a pressing gap between the free end of the pressing plate and the bottom of the residue receiving tray. The pressing plate can cooperate with the residue receiving tray to press and grind the fruit particles on the residue receiving tray through the pressing gap.

[0017] As described above, in a pomegranate pressing mechanism, the inner side of the upper cover is provided with a positioning protrusion, and the surface of the positioning protrusion is wavy or concave-convex.

[0018] A juicing device includes a drive source and a pomegranate juicing mechanism as described in any of the above.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model relates to a pomegranate pressing mechanism and a juicing device using the same mechanism, belonging to the field of household appliance technology. The pomegranate pressing mechanism includes a juice receiving tray, a top cover, and a juicing tray structure. The juicing head has multiple juicing protrusions spaced apart from top to bottom. Each of the juicing protrusions is arranged in a ring on the juicing head. After the drive source is started, the juicing head is driven to perform two types of up-and-down lifting and rotational movements through the drive connection part. During the up-and-down lifting and rotation of the juicing head, the ring-shaped juicing protrusions can squeeze the fruit from multiple directions simultaneously. The multiple juicing protrusions spaced apart from top to bottom can form a multi-layered squeezing structure, which can squeeze the pulp in layers and gradually. In this process, the falling fruit pieces are supported by the juicing protrusion components, increasing the residence time of the fruit pieces on the juicing head and increasing the residence time of the fruit pieces in the juicing area, thereby squeezing the fruit pieces more fully and improving the juice extraction rate.

Detailed Implementation Methods

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 1 to 10 As shown in this embodiment, a pomegranate pressing mechanism includes a juice receiving tray 1, an upper cover 2, and a pressing tray structure. The upper cover 2 is located above the juice receiving tray 1. The pressing tray structure includes a pressing head 3 and a drive connection part 4 fixedly connected to the pressing head 3. The pressing head 3 is located between the juice receiving tray 1 and the upper cover 2. The pressing head 3 is provided with a plurality of pressing protrusions 31 arranged at intervals from top to bottom, and each pressing protrusion 31 is arranged in a ring on the pressing head 3. The drive connection part 4 can be connected to a drive source. When the drive source is working, the drive connection part 4 can move up and down and rotate to drive the pressing head 3 to move up and down and rotate within the juice receiving tray 1. The pressing protrusions 31 support the fruit particles, thereby increasing the residence time of the fruit particles on the pressing protrusions 31 and squeezing the fruit located between the pressing head 3 and the upper cover 2 to achieve juicing.

[0034] Preferably, the fruit to be juiced (such as pomegranate or orange) is placed in the juice receiving tray 1, above the juicing head 3, and the upper cover 2 is placed on top to fix the fruit between the juicing head 3 and the upper cover 2. After the drive source is started, the juicing head 3 is driven to perform two movements through the drive connection part 4: one is a vertical lifting movement, which allows the juicing head 3 to contact fruit particles at different heights; the other is a rotational movement, which allows the juicing protrusions 31 of the juicing head 3 to squeeze the fruit particles from multiple directions. During the vertical lifting and rotation of the juicing head 3, the multiple spaced annular juicing protrusions 31 can squeeze the fruit from multiple angles and at multiple levels. The squeezed juice flows into the juice receiving tray 1 for collection. During this process, the falling fruit particles are supported by the juicing protrusion components 31, increasing the residence time of the fruit particles on the juicing head and increasing the residence time of the fruit particles in the juicing area, thereby squeezing the fruit particles more fully and improving the juice extraction rate.

[0035] Preferably, the annular juicing protrusions 31 can squeeze the fruit simultaneously from multiple directions, and the multiple juicing protrusions 31 spaced apart from top to bottom can form a multi-layered squeezing structure, which can squeeze the pulp in layers and gradually. The annular juicing protrusions 31 can make more full contact with the pulp, reduce pulp waste, and increase juice yield. This design is particularly suitable for fruits with a lot of pulp particles, such as pomegranates and oranges. The annular protrusions can effectively squeeze multiple parts of the pulp and can support the fallen pulp. Unlike traditional electric pomegranate juicers, there is no need to perform a second juicing process on the fallen pulp, reducing the tedious steps before use.

[0036] Furthermore, compared to the simple juicing heads on the market, this multi-ring protrusion design can distribute pressure more evenly and improve the lifespan of the equipment.

[0037] Preferably, taking pomegranate as an example, the residue after juicing the fruit can remain on the surface of the juicing protrusion 31, preventing the residue from entering the juice receiving tray 1 and ensuring the clarity and purity of the juice.

[0038] like Figures 1 to 10 As shown, each of the juicing protrusions 31 in this embodiment is provided with at least one juice guide notch 32. When the juicing head 3 squeezes the fruit, each annular juicing protrusion 31 applies pressure to the pulp from different angles and heights. As the juice is squeezed out, the juice guide notch 32 provides a smooth flow channel. The juice not only flows on the surface of the annular protrusion, but can also flow directly downward through the notch 32. In the process of the juicing head 3 moving up and down and rotating, these notches 32 form a dynamically changing flow channel network, and the juice can flow more quickly along the outer surface of the juicing head 3 to the juice receiving tray 1.

[0039] Preferably, the juice guide notch 32 allows the juice to flow quickly downward on the surface of the juicing head 3, reducing the residence time of the juice on the surface of the juicing head 3. The juice flows away quickly, reducing the possibility of being reabsorbed by the squeezed pulp, improving the overall juice yield. The unobstructed juice guide channel makes the entire juicing process more efficient and shortens the juicing time.

[0040] Furthermore, it can prevent juice from forming a liquid accumulation area between each annular protrusion 31, and prevent juice from overflowing from the connection between the top cover 2 and the juice receiving tray 1 during the juicing process.

[0041] Furthermore, the juice guide notch 32 allows the juice to flow away in a timely manner, reduces the resistance of the juicing head 3 during rotation and lifting, reduces the burden on the drive source, and extends the service life of the equipment.

[0042] Furthermore, the juice guide notch 32 can reduce the residence time of juice on the surface of the juicing head 3, reduce the chance of juice contact with air, reduce oxidation, and maintain better flavor and nutrients.

[0043] Furthermore, the design of the juice guide notch 32 allows some of the fruit pulp residue on the annular protrusion 31 to move relative to the juice guide notch 32 during the juicing head's 3-point rotation. The juice guide notch 32 guides some of the fruit pulp residue to move downwards, preventing excessive fruit pulp residue from accumulating on the annular protrusion 31. This ensures that no excessive fruit pulp residue remains on the annular protrusion 31, guaranteeing the juicing effect while also making cleaning after juicing more convenient.

[0044] like Figures 1 to 10 As shown, the number of juice guiding notches 32 in this embodiment is multiple, and the multiple juice guiding notches 32 are arranged circumferentially at intervals along the corresponding juicing protrusion assembly 31. The juicing protrusion assembly 31 includes multiple arc-shaped protrusions 33 arranged circumferentially at intervals along the juicing head 3, and each juice guiding notch 32 is located between two arc-shaped protrusions 33.

[0045] Preferably, in this embodiment, the juicing protrusion 31 is composed of multiple arc-shaped protrusions 33 spaced apart along the circumference of the juicing head 3, forming a discontinuous annular structure. Each juice guiding notch 32 is located between two adjacent arc-shaped protrusions 33, forming a regularly distributed channel in the circumference of the annular protrusions. When the juicing head 3 rotates, the arc-shaped protrusions 33 squeeze the pulp, while the juice guiding notch 32 can form a dynamically changing juice flow path. During the up-and-down movement of the juicing head 3, multiple arc-shaped protrusions 33 at different heights can apply pressure to different parts of the fruit.

[0046] Preferably, multiple arc-shaped protrusions 33 can more effectively support, grasp and squeeze the pulp, and the circumferentially spaced arc-shaped protrusions 33 make the force on the juicing head 3 more balanced when rotating, reducing vibration and improving equipment stability.

[0047] Furthermore, the design of multiple arc-shaped protrusions 33 can generate a certain stirring effect during rotation, so as to more fully stir and press the pulp and increase the juice yield.

[0048] The multiple circumferentially distributed juice guide gaps 32 provide more juice flow channels, speeding up the juicing process. Furthermore, the arrangement of multiple juice guide gaps 32 reduces the risk of blockage of a single gap. Even if some gaps are temporarily blocked by pulp, other gaps can still ensure that the juice flows smoothly.

[0049] Preferably, the circumferentially distributed arc-shaped protrusions 33 and juice guiding notches 32 design enable the juicing head 3 to better adapt to fruits of different sizes and shapes, and the alternating arrangement of the arc-shaped protrusions 33 and juice guiding notches 32 forms a structure that is more in line with the principles of fluid dynamics, making the juice flow smoother.

[0050] Preferably, in other embodiments, the juicing protrusion 31 is a continuous protrusion structure, with a single juice guide notch 32 located at both ends of the juicing protrusion 31. The continuous protrusion structure provides a stable pressing surface and a supporting surface, making the contact between the fruit and vegetables and the protrusion more compact and continuous throughout the juicing process. This allows for continuous pressing of the fruit pulp and reduces the occurrence of unjuiced fruit pulp falling off. The juice guide notch at both ends of the juicing protrusion allows the pressed juice to flow out effectively from the juice guide notch, thereby avoiding accumulation in the center of the juicing area. Furthermore, the continuous protrusion structure increases the contact area with the fruit and vegetables, which helps to press the fruit and vegetables more thoroughly and improve the juice extraction rate.

[0051] Users can choose the appropriate design based on their actual needs.

[0052] like Figures 1 to 10 As shown, each of the juice-guiding notches 32 of the juicing protrusion component 31 in this embodiment is provided in a one-to-one correspondence.

[0053] Preferably, each juicing protrusion 31 of the juicing head is provided with a juice guiding notch 32, and these notches are aligned with the notches of adjacent protrusions in the vertical direction. This means that the juice guiding notches form a straight line in the height direction of the entire juicing head. Due to the alignment of multiple juice guiding notches, the juice can flow smoothly along the aligned notches, forming a highly efficient straight flow path, reducing flow resistance, reducing the resistance and residence time of the juice in the juicing process, thereby improving the speed and efficiency of juicing.

[0054] Preferably, the aligned notches make cleaning easier, allowing for direct cleaning of the aligned paths and easier removal of clogged fruit residue.

[0055] In other embodiments, the juice guide notch 32 on each of the juicing protrusions 31 is staggered with the juice guide notches 32 on the upper and lower sides of the juicing protrusions 31. This means that the notch positions of adjacent protrusions are not aligned in a straight line, but are staggered at a certain angle or position. Due to the staggered arrangement of the notches, the pressure generated during juicing is not concentrated on a straight line, but is dispersed over a wider area.

[0056] The staggered juice guide notches help distribute pressure evenly throughout the juicing head, reducing localized over-compression. This makes it suitable for juicing fibrous or softer fruits and vegetables. The more even pressure distribution also helps to break down the pulp more thoroughly, rather than just squeezing it, thus better preserving the nutrients and flavor of the juice.

[0057] Because the pressure is distributed more evenly, the pulp can be squeezed more effectively from all angles to extract more juice. The more even pressure distribution also reduces localized impact and wear on the equipment, extending its service life.

[0058] Furthermore, the staggered design prevents juice and pulp from accumulating at a single opening, thus reducing blockages and facilitating juice flow and pulp discharge.

[0059] In other embodiments, on the juicing protrusion 31, some of the juice guiding notches 32 are staggered with some of the juice guiding notches 32 on the upper and lower sides of the juicing protrusion 31, while another part of the juice guiding notches 32 is aligned with some of the juice guiding notches 32 on the upper and lower sides of the juicing protrusion 31. The juice guiding notches 32 are partially aligned and partially staggered on the juicing protrusion 31. This hybrid layout design utilizes the advantages of both alignment and staggering to create a more optimized juicing path.

[0060] Preferably, aligned juice guide notches provide a straight, fast outflow channel, while staggered juice guide notches increase the pressure distribution and the contact area between the juice and pulp during juicing, helping to extract juice more comprehensively. Aligned juice guide notches allow juice to flow out quickly and directly, while staggered juice guide notches ensure full extraction of juice. Combining these two methods can extract juice more effectively while maintaining a high juicing speed. The mixed layout of juice guide notches can handle a variety of fruits and vegetables with different hardness and fiber content.

[0061] Users can choose the appropriate design based on their actual needs.

[0062] like Figures 1 to 10 As shown, each of the juicing protrusions 31 in this embodiment has a downwardly recessed juicing groove 311 on its top. This groove structure can capture and temporarily store more fruit particles and juice during the juicing process.

[0063] When the juicing head 3 rotates and moves up and down, the juicing groove 311 can effectively capture and temporarily retain fruit particles through its concave shape. The design of the juicing groove 311 increases the contact area between the fruit particles and the juicing protrusion component 31, so that the fruit particles receive more uniform and continuous pressure. Moreover, due to the presence of the groove, the residence time of the fruit particles on the juicing protrusion component is extended, which helps to extract juice more thoroughly, thereby improving juicing efficiency, reducing fruit pulp waste, and maximizing the value of each fruit particle.

[0064] Furthermore, this structural design is not only applicable to pomegranates, but also to other juicy fruits (such as oranges or tangerines), demonstrating good versatility.

[0065] like Figures 1 to 10As shown, the juicing groove 311 in this embodiment has an arc-shaped cross-section. The arc-shaped juicing groove can adapt to the shape of the fruit particles more naturally. During the juicing process, the fruit particles can be well positioned in the groove due to the arc-shaped design of the groove, reducing slippage and ensuring that the fruit particles are subjected to uniform pressure during juicing. In addition, during the rotation and lifting of the juicing head, the arc-shaped groove continuously presses the fruit particles. Due to the shape adaptation, the juice can be squeezed out more effectively during the pressing process.

[0066] This reduces the movement of fruit particles during the juicing process. Because the arc-shaped juicing groove is more compatible with the shape of the fruit particles, the fruit particles stay in the groove for a longer period of time, allowing more juice to be squeezed out each time, thus improving the efficiency of juicing.

[0067] Furthermore, the curved groove is particularly suitable for retaining harder fruit pits. Due to the difference in shape and hardness, the pits are not easily squeezed out of the grooves, but remain in the grooves, thus avoiding the pits from breaking and mixing into the juice, ensuring the purity and taste of the juice.

[0068] like Figures 1 to 10 As shown, the juicing disc structure of this embodiment also includes a residue receiving disc 5 connected to the juicing head 3. The residue receiving disc 5 is located below the juicing head 3. The residue receiving disc 5 is provided with a plurality of juice discharge holes 51, through which juice can flow into the juice receiving disc 1.

[0069] Preferably, during the juicing process, the mixture (containing juice and some pulp) produced by the juicing head 3 pressing the fruits and vegetables first enters the pulp receiving tray 5. The juice discharge hole 51 in the pulp receiving tray 5 allows the juice to pass through, while larger solid particles (pulp) are trapped in the pulp receiving tray. The filtered juice flows into the juice receiving tray 1 below through the juice discharge hole 51, thereby achieving effective separation of juice and pulp. Fine filtration through the juice discharge hole on the pulp receiving tray can reduce the amount of pulp entering the final juice, making the juice clearer and purer.

[0070] Preferably, the design of the pulp tray allows the pulp to be concentrated in an easily removable and cleanable location, making it convenient for users to clean the juicer after use and maintain the cleanliness and hygiene of the equipment.

[0071] like Figures 1 to 10 As shown, the side of the juicing head 3 in this embodiment is fixed with a pressing plate 34. This arrangement allows the pressing plate 34 to directly contact and act with the residue receiving tray 5 to press and grind the fruit particles on the residue receiving tray 5.

[0072] Furthermore, in this embodiment, the free end of the pressing plate 34 is arc-shaped, and there is a pressing gap 341 between the free end of the pressing plate 34 and the bottom of the slag receiving plate 5. The pressing plate 34 can cooperate with the slag receiving plate 5 to press and grind the fruit particles on the slag receiving plate 5 through the pressing gap 341.

[0073] When the juicing head 3 rotates, the pressing plate 34 on the side also rotates. The fruit particles are first ground and broken by the juicing head 3, and then some of the fruit particles are thrown onto the residue tray 5. The pressing gap 341 between the arc-shaped free end of the pressing plate 34 and the bottom of the residue tray 5 allows the fruit particles to enter. The fruit particles are then subjected to secondary pressing and grinding by the free end of the pressing plate 34 and the residue tray 5 within the pressing gap 341, releasing more juice.

[0074] Due to the arc-shaped end design, the pressing plate can provide a more concentrated and uniform force when it comes into contact with the fruit particles, so that the fruit particles are effectively broken and ground in the pressing gap. Through the additional pressing action of the pressing plate 34, more juice can be extracted from the fruit particles, reducing waste. This secondary pressing process can effectively improve the juice yield of the juicer.

[0075] The fruit granules, after being pressed and ground, will release juice, while larger residues will remain on the residue tray, achieving effective separation of juice and pulp. Furthermore, the design of the pressing plate 34 can help to further compact the pulp, making it drier and easier for subsequent processing and cleaning.

[0076] like Figures 1 to 10 As shown, the inner side of the top cover 2 in this embodiment is provided with a positioning protrusion 21. When the juicing head 3 starts to rotate to perform the juicing operation, the fruit may try to rotate randomly due to the rotational force. The function of the positioning protrusion 21 is to hold the fruit in place and keep it relatively still, preventing it from sliding or rolling due to rotation.

[0077] Preferably, the positioning protrusion 21 abuts against the skin of the fruit (usually pomegranates or oranges) to hold the fruit in place and prevent it from rotating with the juicing head 3. The juicing head 3 can then more effectively grind and press the fruit, improving the juicing effect.

[0078] Preferably, the surface of the positioning protrusion 21 is wavy or concave-convex, so that when the top cover 2 is pressed on the fruit, the positioning protrusion 21 can be stuck on the fruit's skin, further improving the positioning effect.

[0079] Taking pomegranate as an example, during the juicing process, when the top cover 2 presses on the fruit, the positioning protrusions 21 with wavy or uneven surfaces can hold the fruit granules through the pomegranate skin. Under the upward squeezing and supporting action of the juicing protrusion assembly 31, and during the rotation of the stirring head 3, the fruit granules are stably restricted between the stirring head 3 and the top cover 2, and the juicing protrusion assembly 31 performs a squeezing action on the fruit granules, further improving the juice yield.

[0080] like Figures 1 to 10As shown, the slag receiving plate 5 in this embodiment is provided with a clearance hole 52 for the output end of the drive source to be connected to the drive connection part 4 for transmission. A connecting component 6 is provided between the slag receiving plate 5 and the drive connection part 4 to enable the two to be rotatably connected.

[0081] Specifically, the clearance hole 52 allows the output end of the drive source to directly establish a transmission connection with the drive connection part 4 without being obstructed by the slag receiving tray. The connection component 6 keeps the slag receiving tray 5 and the drive connection part 4 in a rotatable connection, ensuring that the two parts can work together but maintain relatively independent movement. The modular design allows each part to be disassembled and cleaned separately, improving cleaning efficiency. If a part is damaged, it can be replaced separately without replacing the entire juicing system.

[0082] like Figures 1 to 10 As shown, the connecting component 6 in this embodiment includes a first connecting protrusion 61 located on the outside of the driving connecting part 4 and a second connecting protrusion 62 located at the bottom of the clearance hole 52. The first connecting protrusion 61 has a connecting groove 611 corresponding to the second connecting protrusion 62. The second connecting protrusion 62 is inserted into the connecting groove 611. When the driving connecting part 4 rotates and rises under the drive of the driving source, the first connecting protrusion 61 rotates relative to the second connecting protrusion 62 and supports the second connecting protrusion 62 through the connecting groove 611, so as to drive the slag receiving plate 5 to rise synchronously.

[0083] Specifically, the connecting groove 611 on the first connecting protrusion 61 and the second connecting protrusion 62 on the slag receiving plate 5 form a snap-fit ​​engagement, realizing the physical connection between the two components.

[0084] Specifically, the drive source drives the drive connection part 4 to rotate, which in turn drives the juicing head 3 to rotate, while the residue collection tray 5 does not rotate. When the drive connection part 4 rises, the second connection protrusion 62 is supported by the connection groove 611 on the first connection protrusion 61, which drives the residue collection tray 5 to rise synchronously. The first connection protrusion 61 and the second connection protrusion 62 are connected by the connection groove 611, realizing the vertical force transmission, while allowing relative rotation in the horizontal direction. This cleverly realizes the design requirement of transmitting only vertical lifting motion and not rotational motion.

[0085] Preferably, with the above design, when the juicing head 3 rotates to squeeze the fruit, the pulp collection tray 5 does not rotate, thus avoiding the problem of fruit pulp splashing on the pulp collection tray 5, and also reducing noise.

[0086] Furthermore, the mechanism of the juicing head 3 and the pulp tray 5 rising synchronously ensures that the distance between the juicing head 3 and the pulp tray 5 remains constant during the juicing process, preventing excessive fruit particles or ingredients from entering between the juicing head 3 and the pulp tray 5 and causing blockage.

[0087] Preferably, selective power transmission and synchronous lifting are achieved simultaneously using a single connecting component. The convex-concave interlocking structure is simple and reliable, reducing the need for complex transmission mechanisms and lowering mechanical failure rates and maintenance costs.

[0088] Preferably, the snap-fit ​​design facilitates disassembly and assembly, simplifying the cleaning process.

[0089] Preferably, in this embodiment, the drive connection part 4 is a motor drive sleeve. The motor drive sleeve is provided with a snap-fit ​​protrusion for inserting into the stirring head 3, and the inner side of the motor drive sleeve is provided with an insertion hole for inserting into the output end of the drive source.

[0090] In other embodiments, the drive connection part 4 and the stirring head 3 can also be connected by means of snap-fit, thread, spring clamp, etc., and a suitable design can be selected according to actual needs.

[0091] Preferably, in other embodiments, the residue receiving tray 5 is fixedly connected to the juice receiving tray 1, the outer wall of the drive connecting part 4 is provided with a movable groove, and the clearance hole 52 is provided with a sealing block that matches the movable groove. The sealing block can rotate and move up and down relative to the movable groove, so that the drive connecting part 4 can rotate and move up and down in the juice receiving tray 1, thereby driving the movement of the juicing head 3. A suitable design can be selected according to actual needs.

[0092] In other embodiments, the stirring head 3, the slag receiving plate 5, and the drive connection part 4 are integrally formed structures, and the slag receiving plate 5 moves together with the stirring head 3. A suitable design can be selected according to actual needs.

[0093] like Figures 1 to 10 As shown, in this embodiment, a limiting component 7 is provided between the slag receiving tray 5 and the juice receiving tray 1.

[0094] The limiting component 7 and the slag receiving tray 5 form a mechanical constraint. When the drive connecting part 4 rotates, the limiting component 7 prevents the slag receiving tray 5 from rotating with it, while allowing the slag receiving tray 5 to move freely in the vertical direction, maintaining the synchronous upward function with the juicing head 3. Through the synergistic effect of the limiting component 7 and the connecting component 6, the rotational motion and the lifting motion are separated. The juicing head 3 can rotate freely, while the slag receiving tray 5 is restricted to lifting motion only. The slag receiving tray 5 does not rotate, so that the fruit pulp can be collected stably without being thrown out, effectively preventing the problem of fruit pulp splashing caused by high-speed rotation, keeping the working environment clean, and reducing the amount of cleaning work after use.

[0095] Preferably, the combination of the rotating extrusion of the juicing head 3 and the static collection of the residue tray 5 can improve juicing efficiency and juice yield.

[0096] Preferably, the limiting component 7 in this embodiment includes a vertical guide protrusion 71 on the inner wall of the juice receiving tray 1 and a vertical guide groove 72 on the outer wall of the residue receiving tray 5. The guide protrusion 71 is located on the inner wall of the juice receiving tray 1 and is arranged vertically. The vertical guide groove 72 is located on the outer wall of the residue receiving tray 5. The guide protrusion 71 is engaged in the guide groove 72. When the residue receiving tray 5 moves vertically, the guide groove 72 slides along the vertical guide protrusion 71. This structure ensures that the residue receiving tray 5 maintains vertical movement during lifting and lowering and does not rotate with the juice receiving tray 1. The vertical guide structure makes the residue receiving tray 5 maintain high stability during movement, avoiding any unnecessary rotation or swaying, thereby improving juicing efficiency and safety.

[0097] Furthermore, the design of the guide protrusions and grooves is simple and effective, easy to assemble and disassemble, and convenient for users to perform daily cleaning and maintenance.

[0098] Preferably, in other embodiments, the limiting component 7 may also adopt other structures, such as:

[0099] (1) A vertical guide groove is set on the juice receiving tray 1, and a corresponding pin is set on the slag receiving tray 5. The pin slides in the guide groove, allowing the slag receiving tray 5 to move up and down but restricting its rotation.

[0100] (2) Two or more vertical positioning columns are set on the inner wall of the juice receiving tray 1, and corresponding positioning holes are set on the outer wall of the residue receiving tray 5 to ensure that it can only move vertically.

[0101] (3) A vertical slide rail is provided on the inner wall of the juice receiving tray 1, and a corresponding slider is provided on the outer wall of the residue receiving tray 5 to achieve linear motion;

[0102] (4) The inner wall of the juice receiving tray 1 and the outer wall of the residue receiving tray 5 are designed as polygonal cross sections (such as hexagonal or square) to prevent rotation through shape matching, while retaining vertical movement freedom;

[0103] Not limited to the above structures, users can choose the appropriate design according to their actual needs.

[0104] like Figures 1 to 10 As shown, a juicing device in this embodiment includes a drive source and a pomegranate juicing mechanism as described in any of the above embodiments.

[0105] Preferably, the driving source includes a transmission rod 8 and a drive motor located inside the juicing device. The drive motor is connected to the transmission rod 8 and drives the lower juicing head to rise, fall, and rotate through the movement of the upper and lower screws of the screw. It has the advantages of simple structure and convenient operation.

[0106] In other embodiments, the transmission rod 8 can also be implemented using a gear transmission or worm gear transmission structure, and a suitable design can be selected according to actual needs.

[0107] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
