Description

Technical Field

[0001] The utility model relates to the technical field of food processors, and particularly relates to a juice extraction component that is not easily oxidized and has a good taste. Background Art

[0002] The juice extractor is developed on the basis of the conventional juicer. Its main function is to turn fruits into juice to improve the taste and facilitate drinking. Compared with the juicer, it obtains juice through low-speed screw extrusion. The lower the extrusion speed, the better. It slowly squeezes out the juice like squeezing a towel without destroying the fruit cell structure, thus preserving the fruit nutrients. Moreover, the low-speed juice extraction does not generate high heat and also avoids the problem of juice oxidation due to heat. In the related art, a motor is combined with a speed reduction structure to output slow speed and large torque to meet the large torque required for slow squeezing by the screw.

[0003] The application number is CN201990001351.0, and the invention name is "Juicer", which discloses that two inclined surfaces are respectively formed along the rotation direction of the discharge hole. The upstream inclined surface slopes downward along the rotation direction of the cutting part from the discharge hole, and the downstream inclined surface slopes towards the discharge hole. The height of the joint part between the downstream inclined surface and the discharge hole is lower than the height of the inner bottom plate surface of the hopper shell. However, the technical problem existing in this technical solution is that: along the rotation direction of the screw, the material is pushed from near the upstream inclined surface of the bottom plate surface of the hopper shell until the upper end of the downstream inclined surface. Since the upper ends of the downstream inclined surface and the upstream inclined surface are on the same horizontal plane and there is no obvious height difference between them, there is no effect of gravitational acceleration. The material is continuously pushed relatively uniformly along the bottom plate surface of the hopper shell until it enters the discharge hole, and the movement time on the bottom plate surface of the hopper shell is relatively long, which easily causes the material to oxidize during this period and affects the taste of the juice.

[0004] The application number is CN202111432105.0, and the invention name is "Juice Extraction and Filtration Assembly of a Juice Extractor with a Pre-Crushing Function", which discloses that the installation partition has a material dropping port, and the upper ends of the material receiving side and the material discharging side of the material dropping port are on the same horizontal plane. However, the technical problem existing in this technical solution is that: the material moves on the installation partition along the rotation direction of the screw, from near the material receiving side of the material dropping port to near the material discharging side of the material dropping port. Since the upper ends of the material receiving side and the material discharging side of the material dropping port are on the same horizontal plane and there is no obvious height difference between them, the material is continuously pushed relatively uniformly along the installation partition until it enters the material dropping port. When moving on the installation partition, there is no effect of gravitational acceleration, and the movement time of the material on the installation partition is relatively long, which easily causes the material to oxidize during this period and affects the taste of the juice.

[0005] The above-disclosed technical solutions all have the following technical problems: The material is continuously pushed relatively uniformly on the bottom plate until it enters the blanking port. During the movement on the bottom plate, there is no effect of gravitational acceleration, which easily causes the material to oxidize during this period and affects the taste of the juice. Utility Model Content

[0006] The purpose of the present utility model is to provide a juice extraction assembly to solve the technical problem that the material is prone to oxidation and affects the taste of the juice.

[0007] To solve the above technical problems, the present utility model provides a juice extraction assembly, including a screw rod, and a material guiding disc rotatably connected to the upper end of the screw rod. The material guiding disc is provided with a body and a blanking port along the rotation direction of the screw rod. The blanking port is provided with a material receiving side and a material discharging side along the rotation direction of the screw rod;

[0008] A material guiding platform is provided in the central area of the body at the blanking port. The material guiding platform has a conical surface extending downward and obliquely outward from the center. The upper side of the upstream end of the conical surface is connected to the root of the material receiving side, and the lower side of the downstream end of the conical surface is connected to the root of the material discharging side.

[0009] Preferably, the conical surface and the root of the material receiving side are smoothly connected through a blocking portion, and the blocking portion extends from the upper end to the lower end of the conical surface.

[0010] Preferably, the lower surface of the body near the material receiving side is recessed inward to form a groove. One side surface of the groove close to the center is a material guiding surface, and the material guiding surface is adjacent to the blocking portion.

[0011] Preferably, a cutting edge is formed at the connection between the material guiding surface and the blocking portion, and the cutting edge extends from the lower surface of the body to the lower end of the conical surface.

[0012] Preferably, the height of the material guiding surface gradually decreases along the rotation direction of the screw rod.

[0013] Preferably, the upper surface of the body near the material discharging side is recessed downward to form a diversion surface, and the diversion surface is smoothly connected to the upper side of the downstream end of the conical surface.

[0014] Preferably, the height of the diversion surface gradually increases along the rotation direction of the screw rod.

[0015] Preferably, the area of the diversion surface is S1, the area of the conical surface is S2, and the area of the blocking portion is S3. S2:S1 is 1.5 - 3, and S2:S3 is 5.5 - 8.

[0016] Preferably, the blocking portion is an inclined surface or an arc surface that gradually extends downward and obliquely outward from the center.

[0017] Preferably, the material guide plate is further provided with a peripheral edge along the outer periphery of the main body, the screw is rotated from the material-facing side to the material-receiving side, and the spacing between the upper surface of the peripheral edge and the upper surface of the main body is set from small to large.

[0018] The beneficial effects of the utility model are:

[0019] 1. The utility model provides a juice extraction component, which is connected to the root of the material-facing side by the upper side of the upstream end of the conical surface, and connected to the root of the material-receiving side by the lower side of the downstream end of the conical surface, that is, the material moves from the material-facing side to the material-receiving side with a height difference from the material-guiding plate, during which gravity acceleration will be generated. Along the direction of rotation of the screw, the material will accelerate in a certain section of the travel on the material-guiding plate, and the running time of the material on the material-guiding plate will be greatly shortened, making it difficult for the material to be oxidized, thereby ensuring the taste of the juice; secondly, because the material-guiding table is a downwardly inclined conical surface, the conical surface supports the material, which can Allow the contact material to run a path on the conical surface. The supporting effect of the conical surface will not allow the material to fall directly into the screw, but may be pushed to the material-facing side for pre-cutting. At the same time, there is an obvious height difference from the back material side to the material-facing side, and it will fall a short distance at the material dropout due to gravity. Combined with the supporting effect of the conical surface on large pieces of material, the large pieces of material may be at the height that can be effectively pre-cut on the material-facing side, which greatly increases the probability of the material being cut and prevents large pieces of material from directly entering the screw, ensuring that the material can be fully pre-cut before entering the screw, reducing the load of the screw biting and grinding.

[0020] 2. The conical surface and the root of the material-facing side are smoothly connected by a blocking part, and the blocking part extends from the upper end to the lower end of the conical surface. The axial height of the blocking part is greater than the thickness of the material-facing side. A section of the food can be abutted by the blocking part, which provides a fulcrum for this cutting and can be effectively cut on the material-facing side, thereby preventing the fiber material from continuously idling or entangled on the body, thereby improving the juicing efficiency.

[0021] 3. The groove is formed by the inward depression of the lower surface of the body close to the material-facing side, and the guide surface adjacent to the blocking part in the groove, so that the material can enter the guide surface from the blocking part, and the travel of the material from the blocking part to the groove is greatly shortened, so that the material sheared on the material-facing side can smoothly enter the groove, and then smoothly enter the screw to squeeze out the juice; and a cutting edge is formed at the connection between the guide surface and the blocking part, and at the same time, the cutting edge extends from the lower surface of the body to the lower end of the conical surface. Based on the fact that high-fiber food is blocked by the blocking part, the fibrous food has good flexibility, so a part of it is bent into the groove, and a part of it may still be attached to the blocking part. The blocking part provides a fulcrum for this cutting, and the cutting edge can cut the food, so that the material can be cut smaller before it completely enters the groove, reducing the burden of the screw carrying large particles, allowing the screw to fully squeeze the material to squeeze out the juice, thereby improving the juice yield.

[0022] 4. A diversion surface is formed by downward depression on the upper surface of the main body near the back material side, and the diversion surface is smoothly connected to the upper side of the downstream end of the conical surface; so that there is a height difference when the material moves from the area of the main body provided with the diversion surface to the material receiving side. During this period, gravitational acceleration will be generated, so that a part of the large pieces of material will accelerate radially from the area of the main body provided with the diversion surface to the material receiving side through the conical surface under the action of gravitational acceleration. While the falling height of the large pieces of material meets the shearing requirements, it also shortens the time when the large pieces of material are cut on the material receiving side, greatly improving the pre-cutting efficiency.

[0031] The following will further elaborate on the present utility model in detail in conjunction with the drawings and specific embodiments.

[0032] Please refer to Figures 1-5, an embodiment of the present utility model provides a juice extraction assembly, including a screw 1 and a material guiding plate 2, and the material guiding plate 2 is rotatably connected to the upper end of the screw 1.

[0033] The material guiding plate 2 is provided with a body 21 and a material dropping port 22 along the rotation direction of the screw 1. The material dropping port 22 is provided with a material receiving side 221 and a material back side 222 along the rotation direction of the screw 1. A material guiding platform is provided in the central area of the body 21 at the position of the material dropping port 22. The material guiding platform has a conical surface 211 extending downward and obliquely outward from the center. The upper side of the upstream end of the conical surface 211 is connected to the root of the material receiving side 221, and the lower side of the downstream end of the conical surface 211 is connected to the root of the material back side 222.

[0034] It can be understood that since the upper side of the upstream end of the conical surface 211 is connected to the root of the material receiving side 221, and the lower side of the downstream end of the conical surface 211 is connected to the root of the material back side 222, that is, there is a height difference for the material to move from the material guiding plate 2 near the material receiving side 221 to the material back side 222. During this period, gravitational acceleration will be generated. Along the rotation direction of the screw 1, the material will accelerate during a certain section of the journey on the material guiding plate 2, and the running time of the material on the material guiding plate 2 will be greatly shortened, making the material not easily oxidized and ensuring the taste of the juice.

[0035] Secondly, since the material guiding platform is a downwardly inclined conical surface 211, compared with a vertical surface and an inclined surface where the material guiding platform extends obliquely from the outside to the center, the material will directly fall into the screw 1 from the outer end of the inclined surface or directly fall into the screw 1 from the upper end of the vertical surface, which cannot play a supporting role for the material.

[0036] The conical surface 211 plays a supporting role for the material and can allow the contacting material to run a certain path on the conical surface 211. Therefore, some large pieces of material in contact with the conical surface 211 will not directly fall into the screw 1 under the supporting action of the conical surface 211 and may be pushed to the material receiving side 221 for pre-cutting. At the same time, the upper side of the upstream end of the conical surface 211 is connected to the root of the material receiving side 221, and the lower side of the downstream end of the conical surface 211 is connected to the root of the material back side 222. When the material moves from the material back side 222 to the material receiving side 221, it will fall a small height at the material dropping port 22 under the action of gravity. Combining with the supporting action of the conical surface 211 on the large pieces of material, the large pieces of material may just be at the height where they can be effectively pre-cut on the material receiving side 221, greatly increasing the probability of the material being cut, so that the large pieces of material will not directly enter the screw 1, ensuring that the material can be fully pre-cut before entering the screw 1 and reducing the load of the screw 1 on biting and grinding.

[0037] Specifically, as Figure 2As shown, the conical surface 211 and the root of the material-facing side 221 are smoothly connected by a blocking portion 23, and the blocking portion 23 extends from the upper end to the lower end of the conical surface 211. The material-facing side 221 is a shearing edge 214 that can cooperate with the first cutting edge 3 to shear the material.

[0038] It is understandable that fibrous food materials are difficult to be cut due to their strong toughness. However, when the food materials run to the blocking portion 23, since the blocking portion 23 extends from the upper end to the lower end of the conical surface 211, the axial height of the blocking portion 23 is greater than the thickness of the material-facing side 221, and a portion of the food materials can be abutted by the blocking portion 23, and can be cut more effectively by the first cutting edge 3. For example, when cutting celery, due to its high fiber content, it may be entangled around the first cutting edge 3, and rotate with the first cutting edge 3, and cannot be cut. However, when moving to the blocking portion 23, the material-facing side 221 and the first cutting edge 3 cooperate to shear, and the celery located below the first cutting edge 3 is blocked by the blocking portion 23, providing a focus point for this cutting, so the first cutting edge 3 can cut and separate the celery below from the celery above, and the food materials below are cut off and enter the screw 1, so as to avoid the material from continuously idling on the body 21, and improve the juicing efficiency.

[0039] More specifically, the blocking portion 23 is an inclined surface or an arc-shaped surface extending gradually downward from the center outward, giving the material moving thereto an oblique downward guiding effect, so that the material smoothly enters the lower part of the guide plate 2. The blocking portion 23 can also be set to other forms, as long as the height of the blocking portion 23 in the axial direction is greater than the thickness of the material-facing side 221. The blocking portion 23 is preferably an arc-shaped surface, which can ensure a smooth connection between the conical surface 211 and the root of the material-facing side 221.

[0040] In addition, if Figure 3 As shown, the lower surface of the body 21 near the material-facing side 221 is inwardly concave to form a groove 212, and the side surface of the groove 212 near the center is a guide surface 213, and the guide surface 213 is adjacent to the blocking portion 23, so that the material can enter the guide surface 213 from the blocking portion 23, and the travel of the material from the blocking portion 23 to the groove 212 is greatly shortened, so that the material sheared on the material-facing side 221 can smoothly enter the groove 212, and then smoothly enter the screw 1 to squeeze out juice, thereby improving the juice extraction efficiency. Among them, the height of the guide surface 213 gradually decreases along the rotation direction of the screw 1, and the material will also be squeezed between the screw 1 and the bottom surface of the guide surface 213, so that the material is gradually squeezed into finer particles during the rotation of the screw 1.

[0041] Specifically, a cutting edge 214 is formed at the connection between the guide surface 213 and the blocking portion 23, and the cutting edge 214 extends from the lower surface of the body 21 to the lower end of the conical surface 211. It can be understood that the high-fiber food below the first cutting edge 3 is blocked by the blocking portion 23, and the fiber food has good flexibility. A part of it is bent into the groove 212, and a part of it may still be attached to the blocking portion 23. The blocking portion 23 provides a fulcrum for this cutting. The cutting edge 214 can cut the food, so that the material can be cut smaller before it completely enters the groove 212, reducing the burden of the screw 1 carrying large particles of material, allowing the screw 1 to fully squeeze the material to extract juice, and improve the juice yield.

[0042] In addition, if Figures 4-5 As shown, the upper surface of the body 21 near the back material side 222 is concave downward to form a guide surface 215, and the guide surface 215 is smoothly connected to the upper side of the downstream end of the tapered surface 211. It can be understood that the closer the body 21 is to the blanking port 22, the more it sinks, so that the material moves from the area of ​​the body 21 with the guide surface 215 to the material-facing side 221 with a height difference. During this period, gravity acceleration will be generated, so that a part of the bulk material, under the action of gravity acceleration, is accelerated in the radial direction from the area of ​​the body 21 with the guide surface 215 to the material-facing side 221 through the tapered surface 211. The falling height of the bulk material not only meets the shearing requirements, but also shortens the time for the bulk material to be cut on the material-facing side 221, greatly improving the pre-cutting efficiency.

[0043] Among them, the height of the guide surface 215 gradually increases along the rotation direction of the screw 1, and the closer to the blanking port 22, the greater the height of the guide surface 215, that is, the closer the body 21 is to the blanking port 22, the more it sinks; at the same radial height, the component of gravity gradually increases along the circumferential direction, that is, the closer to the blanking port 22, the greater the component of gravity. Therefore, along the rotation direction of the screw 1, the material passes through the body 21 from the material-facing side 221 and finally to the back material side 222, and the component of gravity gradually increases, and a part of the small pieces of material are accelerated to enter the blanking port 22, which plays a better role in guiding the material. In addition, the height of the guide surface 215 gradually increases, which allows small materials to have enough space to pass through the gap between the body 21 and the first cutting edge 3, and then smoothly fall into the screw 1. It can also prevent some small materials from being stuck in the gap between the body 21 and the first cutting edge 3, reducing the motor load.

[0044] Specifically, Figure 5 As shown, the area of ​​the guide surface 215 is S1, the area of ​​the conical surface 211 is S2, the area of ​​the blocking portion 23 is S3, S2: S1 is 1.5-3, S2: S3 is 5.5-8. S1 is preferably 155 mm 2 , S2 is preferably 340mm 2 , S3 is preferably 55mm2 ; alternatively, S1 is preferably 145 mm 2 , S2 is preferably 319 mm 2 , S3 is preferably 40 mm 2 .

[0045] When S2:S1 is 1.5 - 3 and S2:S3 is 5.5 - 8, with the central angle remaining unchanged, the larger the flow guiding surface 215, that is, the greater the height by which the area of the main body 21 provided with the flow guiding surface 215 sinks, determines the magnitude of the acceleration provided by the component of gravity to the material; the magnitude of the acceleration matches the size of the conical surface 211. A part of the material can run along the conical surface 211 after being accelerated in the area of the main body 21 provided with the flow guiding surface 215. The conical surface 211 has a supporting effect on large pieces of material, and the path of the material running on the conical surface 211 can just be pushed to the blocking part 23, neither falling into the screw 1 before reaching the blocking part 23 due to the conical surface 211 being too large, nor flipping to the upper surface of the main body 21 due to the conical surface 211 being too small. This enables large pieces of material to be effectively pre-cut on the material receiving side 221, greatly increasing the probability of the material being cut, preventing large pieces of material from directly entering the screw 1, ensuring that the material can be fully pre-cut before entering the screw 1, and reducing the load of the screw 1 on biting and grinding.

[0046] If S2:S1 is less than 1.5 and S2:S3 is less than 5.5, the conical surface 211 is too small. Under the acceleration of the component of gravity, a part of the material directly flips to the upper surface of the main body 21 along the conical surface 211 before contacting the blocking part 23, and cannot be effectively pre-cut on the material receiving side 221, resulting in a significant reduction in cutting efficiency. If S2:S1 is greater than 3 and S2:S3 is greater than 8, the conical surface 211 is too large, and the acceleration provided by the component of gravity to the material is insufficient. Some of the material falls into the screw 1 along the conical surface 211 before reaching the blocking part 23, increasing the load of the screw 1 on biting and grinding and not allowing for sufficient pre-cutting.

[0047] As a preferred embodiment, as Figures 2-4 shown, the material guiding plate 2 is further provided with a peripheral edge 24 along the outer periphery of the main body 21. The screw 1 rotates from the material receiving side 221 to the material discharging side 222. The distance between the upper surface of the peripheral edge 24 and the upper surface of the main body 21 is set from small to large, that is, the material guiding plate 2 sinks along the rotation direction of the screw 1, playing a good role in guiding the material. There is a height difference from the material guiding plate 2 moving from near the material receiving side 221 to the material discharging side 222. During this period, gravitational acceleration will be generated. Along the rotation direction of the screw 1, the material will accelerate in a certain section of the material guiding plate 2. The running time of the material on the material guiding plate 2 will be greatly shortened, making it difficult for the material to oxidize and ensuring the taste of the juice. Secondly, as Figure 3As shown, the surrounding edge 24 can be in the shape of a closed circular ring. The surrounding edge 24 can be provided with an opening at the blanking port 22. The surrounding edge 24 has a protective effect on the main body 21 and can also play a blocking role when the material moves radially outward, making it difficult for the material to move towards the outer edge of the main body 21. Furthermore, it can avoid the situation of material jamming at the edge of the guide plate 2 and the feeding cylinder, ensuring that all the materials can fall into the blanking port 22 and guaranteeing the juice yield.

[0048] In addition to the above preferred embodiments, the technical solutions protected by the present utility model are not limited to the above embodiments. It should be noted that the combination of multiple technical solutions in any one embodiment, as well as the combination of the technical solution of any one embodiment with the technical solutions in one or more other embodiments, are within the protection scope of the present utility model. Although the present utility model has been described in detail with general descriptions and specific embodiments above, based on the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all belong to the scope required to be protected by the present utility model.
