Description

Technical Field

[0001] The utility model belongs to the technical field of beverage extraction equipment, and specifically provides a centrifugal extractor. Background Art

[0002] Existing extraction equipment generally extracts coffee and other substances to be extracted by means of soaking, hot water brewing, cooking, etc., so as to extract the target substances in the substances to be extracted and obtain the final drinking solution.

[0003] The principle of the above extraction method is to dissolve and diffuse the target substances in coffee and other substances to be extracted into the solution by means of molecular diffusion. This not only takes a long time, but also makes the substances to be extracted still retain a large amount of target substances after extraction, resulting in incomplete extraction and even affecting the taste of the final drinking solution.

[0004] Moreover, the substances to be extracted are easily adhered to the peripheral wall of the extraction equipment and are not easy to clean, increasing the cleaning difficulty of the extraction equipment. Summary of the Utility Model

[0005] An object of the utility model is to solve the problem that the existing extraction equipment has poor integrity in extracting substances to be extracted.

[0006] To achieve the above object, the utility model provides a centrifugal extractor, comprising:

[0007] A liquid storage container;

[0008] A driving device, which is relatively fixed to the liquid storage container;

[0009] An inner filter container, which is arranged in the liquid storage container and is drivingly connected to the driving device;

[0010] An outer filter container, which is arranged between the liquid storage container and the inner filter container and is drivingly connected to the driving device;

[0011] Wherein, at least one of the inner filter container and the outer filter container is provided with a flow disturbing structure to disturb the substances in at least one of them.

[0012] Optionally, the flow disturbing structure includes at least one first flow disturbing rib arranged on the inner filter container.

[0013] Optionally, the circumferential side wall of the inner filter container is denoted as the first circumferential side wall, and at least one of the inner and outer sides of the first circumferential side wall is provided with at least one of the first flow disturbing ribs.

[0014] Optionally, 2 to 12 of the first flow disturbing ribs are arranged on the inner side of the first circumferential side wall.

[0015] Optionally, the first spoiler rib extends from the bottom end to the top end of the first circumferential side wall; and / or, the inscribed circle diameter of all the first spoiler ribs on the inner side of the first circumferential side wall first decreases and then increases from the bottom end to the top end of the first circumferential side wall.

[0016] Optionally, the spoiler structure includes at least one second spoiler rib provided on the outer filter container.

[0017] Optionally, the circumferential side wall of the outer filter container is denoted as the second circumferential side wall, and at least one of the inner and outer sides of the second circumferential side wall is provided with at least one second spoiler rib.

[0018] Optionally, 2 to 12 second spoiler ribs are provided on the inner side of the second circumferential side wall.

[0019] Optionally, the second circumferential side wall is inclined outward from bottom to top, and the second spoiler rib extends from the bottom end to the top end of the second circumferential side wall.

[0020] Optionally, the centrifugal extractor further includes a pressing block detachably installed in the inner filter container. At least one avoidance groove is provided on the circumferential side wall of the pressing block, and the avoidance groove is adapted to the first spoiler rib on the inner side of the first circumferential side wall to prevent the pressing block from rotating relative to the inner filter container.

[0021] Based on the foregoing description, those skilled in the art can understand that in the foregoing technical solution of the present utility model, by configuring the inner filter container driven by the driving device, the inner filter container can perform centrifugal extraction on the extract to be extracted placed therein by rotating, and the extracted substance can be thrown out of the inner filter container. During centrifugal extraction, it is easier to throw the target substance on the extract to be extracted out of the inner filter container. Therefore, the centrifugal extractor of the present utility model improves the integrity of the extraction of the extract to be extracted. Moreover, the present utility model can also perform secondary filtration on the extracted target substance through the outer filter container provided outside the inner filter container, improving the purity and taste of the final drinking solution. The present utility model also sets a spoiler structure on at least one of the inner filter container and the outer filter container to disturb the substances in at least one of them. Especially when cleaning the inner filter container and the outer filter container, the water in the inner filter container and the outer filter container can be disturbed by the spoiler structure to form a turbulent flow, increasing the impact force of the water flow on the inner filter container and the outer filter container, thereby improving the cleaning effect of the inner filter container and the outer filter container and reducing the cleaning difficulty of the extraction equipment.

[0022] Further, by providing at least one first spoiler rib on the inner filtration container, the inner filtration container can disrupt the water flow by means of the first spoiler rib, increasing the impact force of the water flow on the inner filtration container, thereby improving the cleaning effect of the inner filtration container.

[0023] Further, by making the inscribed circle diameter of all the first spoiler ribs on the inner side of the first circumferential side wall first decrease and then increase from the bottom end to the top end of the first circumferential side wall, the degree of turbulent flow of the water flow inside the inner filtration container in the axial direction is different, and thus the water flow can surge up and down, strengthening the cleaning effect of the inner filtration container.

[0024] Further, by providing at least one second spoiler rib on the outer filtration container, the outer filtration container can disrupt the water flow by means of the second spoiler rib, increasing the impact force of the water flow on the outer filtration container, thereby improving the cleaning effect of the outer filtration container.

[0049] Those skilled in the art should understand that the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments of the present utility model. This part of the embodiments is intended to explain the technical principles of the present utility model and is not intended to limit the protection scope of the present utility model. Based on the embodiments provided by the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall still fall within the protection scope of the present utility model.

This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0051] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. For example, the terms "installation", "connection", "connected" and "fixed", without special description, can specifically be any feasible connection forms such as bolt connection, screw connection, welding, plug connection, riveting, fusion welding, snap connection, etc.

[0052] As Figures 1 to 5 shown, in some embodiments of the present utility model, the centrifugal extractor 001 innovatively uses centrifugal extraction technology and includes a fuselage 100, a liquid storage container 200, a driving device 300, an inner filter container 400, an outer filter container 500, and an optional pressing block 600.

[0053] Among them, a top cavity 101 and a bottom cavity 102 are defined on the fuselage 100. The top cavity 101 is used to arrange the liquid storage container 200, the inner filter container 400, and the outer filter container 500, and the bottom cavity 102 is used to arrange the driving device 300. Of course, on the premise that the liquid storage container 200, the driving device 300, the inner filter container 400, and the outer filter container 500 can be installed, those skilled in the art can also set the fuselage 100 into any other feasible shape according to needs, such as a hollow barrel-shaped member. Or, those skilled in the art can also omit the setting of the fuselage 100 according to needs.

[0054] Among them, the liquid storage container 200 is used to hold the liquid 004 added to the centrifugal extractor 001 (as Figure 11 shown), or the liquid 004 generated during the operation of the centrifugal extractor 001.

[0055] Among them, the driving device 300 is relatively fixed to the liquid storage container 200. Specifically, it can be fixedly connected to the fuselage 100.

[0056] Among them, the circumferential side wall of the inner filter container 400 is denoted as the first circumferential side wall 410 and is provided with a plurality of first filter holes 411. The inner filter container 400 is arranged in the liquid storage container 200 and is drivingly connected to the driving device 300. The inner filter container 400 is used to perform centrifugal extraction on the extractant 002 placed therein (as Figure 11 shown) by rotation, and enable the extracted target substance 003 (as Figure 11 shown) to pass through the first filter holes 411.

[0057] Among them, the circumferential side wall of the outer filter container 500 is denoted as the second circumferential side wall 510 and is provided with a plurality of second filter holes 511. The outer filter container 500 is arranged between the liquid storage container 200 and the inner filter container 400 and is drivingly connected to the driving device 300. The aperture of the second filter holes 511 is smaller than the aperture of the first filter holes 411 to filter the extracted target substance 003 through the second filter holes 511.

[0058] Among them, the pressing block 600 is detachably installed in the inner filter container 400 and is used to press the extractant 002 in the inner filter container 400 to prevent the extractant 002 from being thrown out of the inner filter container 400. A feeding hole 601 is provided in the middle of the pressing block 600 to facilitate the user to feed the extractant 002 and water into the inner filter container 400. Of course, those skilled in the art can also set the pressing block 600 as a solid plate-like structure (omitting the feeding hole 601) according to needs, or omit the setting of the pressing block 600.

[0059] Those skilled in the art can understand that the centrifugal extractor 001 of the present utility model is configured with an inner filter container 400 driven by a driven device 300, enabling the inner filter container 400 to perform centrifugal extraction on the extractable substance 002 placed therein by rotation, and allowing the extracted substance to pass through the first filter holes 411. During centrifugal extraction, it is easier to throw the target substance 003 on the extractable substance 002 out of the inner filter container 400. Therefore, the centrifugal extractor 001 of the present utility model improves the integrity of the extraction of the extractable substance 002. Moreover, the present utility model can also filter the extracted target substance 003 through the outer filter container 500, improving the purity and taste of the final drinking solution (the liquid 004 containing the target substance 003).

[0060] It should be noted that in the present utility model, the extractable substance 002 includes coffee powder and / or tea powder. For example, the extractable substance 002 can be coffee powder or tea powder, or a mixture of coffee powder and tea powder.

[0061] Of course, those skilled in the art can also, according to needs, make the extractable substance 002 include any other feasible powdery substances, such as soybean powder, mung bean powder, cocoa powder, lemon, etc.

[0062] During the process of extracting the extractable substance 002 by the centrifugal extractor 001 of the present utility model, a liquid 004 in which the target substance 003 is dissolved is generated.

[0063] Among them, the target substance 003 can be a substance soluble in water in the extractable substance 002. The liquid 004 is the liquid substance of the extractable substance 002 itself or can be water. This water can be hot water, normal temperature water or cold water in terms of temperature, and can be pure water, tap water, mineral water or water dissolved with specific substances (such as sugar, milk, essence, etc.) in terms of composition.

[0064] As Figures 1 to 3 shown, in some embodiments of the present utility model, a knob 110 can also be provided on the fuselage 100 to adjust the rotation speeds of the inner filter container 400 and the outer filter container 500 through this knob 110.

[0065] In addition, in other embodiments of the present utility model, those skilled in the art can also, according to needs, omit the setting of the knob 110 and control the rotation speeds of the inner filter container 400 and the outer filter container 500 through other buttons or other devices. Among them, the other buttons can be physical buttons provided on the centrifugal extractor 001 or virtual buttons displayed on the display screen of the centrifugal extractor 001. The other devices can be a remote control adapted to the centrifugal extractor 001, or devices such as a mobile phone or a tablet computer communicatively connected to the centrifugal extractor 001.

[0066] As Figures 1 to 4As shown, in some embodiments of the present utility model, the liquid storage container 200 is placed in the top cavity 101 of the fuselage 100 and can be detachably connected to the fuselage 100 to facilitate the user to remove the liquid storage container 200 for cleaning. Of course, those skilled in the art can also fixedly connect the liquid storage container 200 to the fuselage 100 according to needs.

[0067] When the liquid storage container 200 is detachably connected to the fuselage 100, the liquid storage container 200 and the fuselage 100 are provided with an anti-rotation structure to prevent the liquid storage container 200 from rotating relative to the fuselage 100. For example, Figure 1 and Figure 2 As shown, a protruding structure (not marked in the figure) is provided on the peripheral wall of the liquid storage container 200, and a slot (not marked in the figure) matching the protruding structure is provided on the fuselage 100. The protruding structure is inserted into the slot, thereby realizing the circumferential fixation of the liquid storage container 200 and the fuselage 100. A hanging ear (not marked in the figure) can also be provided on one side of the liquid storage container 200 away from the protruding structure, and a card slot (not marked in the figure) corresponding to the hanging ear is provided on the fuselage 100. The hanging ear is embedded in the card slot to further realize the circumferential fixation of the liquid storage container 200 and the fuselage 100.

[0068] When the liquid storage container 200 is fixedly connected to the fuselage 100, the two can be fixedly connected together through fixing members, structures or materials such as screws, buckles, adhesives, etc.

[0069] As Figures 1 to 4 shown, in some embodiments of the present utility model, a liquid discharge channel 201 is provided on the liquid storage container 200 to discharge the liquid 004 in the liquid storage container 200 through the liquid discharge channel 201.

[0070] As Figure 1 、 Figure 2 and Figure 4 shown, in some embodiments of the present utility model, an avoidance hole 202 is provided on the bottom wall of the liquid storage container 200 to avoid the driving device 300, so as to ensure that the driving device 300 is drivingly connected to the inner filter container 400 and the outer filter container 500. The liquid storage container 200 is also provided with an annular baffle 210 extending from its bottom wall to the top side to prevent the liquid 004 in the liquid storage container 200 from flowing out through the avoidance hole 202.

[0071] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, in some embodiments of the present utility model, the driving device 300 includes a motor 310 and a connector 320. The motor 310 is fixedly connected to the fuselage 100 through its housing, and the motor 310 is fixedly connected to the connector 320 through its rotating shaft. The connector 320 is fixedly connected to the inner filter container 400 and the outer filter container 500, so that the motor 310 drives the inner filter container 400 and the outer filter container 500 to rotate through the connector 320.

[0072] Specifically, a through hole is formed between the top cavity 101 and the bottom cavity 102 of the fuselage 100. The rotating shaft of the motor 310 passes through the through hole, so that the main part of the motor 310 is located in the bottom cavity 102, and the connector 320 is located in the top cavity 101.

[0073] Among them, the connector 320 can be any feasible structure such as a plate-like structure, a columnar structure, a Y-shaped structure, a triangular structure, etc. A rotating shaft hole (not marked in the figure) matching the rotating shaft of the motor 310 is provided on the connector 320 to realize the fixed connection between the connector 320 and the rotating shaft of the motor 310 through the rotating shaft hole. Alternatively, a connecting shaft is provided on the connector 320, and the connecting shaft and the rotating shaft of the motor 310 are fixedly connected together through a coupling.

[0074] Alternatively, those skilled in the art can also, according to needs, connect the connector 320 and the rotating shaft of the motor 310 in any other feasible connection manner, such as welding, bolt connection, flange connection, etc.

[0075] Alternatively, those skilled in the art can also, according to needs, detachably connect the connector 320 and the rotating shaft of the motor 310, so that the connector 320 can be detached together with the detachable liquid storage container 200.

[0076] Furthermore, the connector 320 is fixedly connected to the inner filter container 400 and the outer filter container 500, so that the motor 310 drives the inner filter container 400 and the outer filter container 500 to rotate synchronously through the connector 320. For example, the connector 320 is welded or screwed to the outer filter container 500, and the inner filter container 400 is welded or screwed to the outer filter container 500.

[0077] In other embodiments of the present utility model, those skilled in the art can also, according to needs, set the connector 320 to two parts that can rotate synchronously and are detachably connected, and fixedly connect one part to the rotating shaft of the motor 310, and fixedly connect the other part to the inner filter container 400 and the outer filter container 500. Exemplarily, convex teeth are respectively provided at one ends of the two parts of the connector 320 that are close to each other, so that the two parts are engaged together through the two convex teeth, and thus the circumferential fixation of the two parts is realized.

[0078] In addition, in other embodiments of the present utility model, those skilled in the art can also, according to needs, set the driving device 300 in any other feasible form. For example, the driving device 300 only includes a motor 310, and the rotating shaft of the motor 310 is directly fixedly connected to at least one of the inner filtering container 400 and the outer filtering container 500. When the rotating shaft of the motor 310 is only fixedly connected to one of the inner filtering container 400 and the outer filtering container 500, the one is connected to the other of the inner filtering container 400 and the outer filtering container 500 through connection means such as welding, riveting, snap connection, bolt connection, etc.

[0079] As Figure 1 , Figures 3 to 7 shown, in some embodiments of the present utility model, a turbulence structure 700 is provided on at least one of the inner filtering container 400 and the outer filtering container 500 to disturb the substances in at least one of them. The substances can be the extractable substance 002 or the liquid 004 described above.

[0080] Those skilled in the art can understand that by providing the turbulence structure 700 on at least one of the inner filtering container 400 and the outer filtering container 500, the substances in at least one of them are disturbed. Especially when cleaning the inner filtering container 400 and the outer filtering container 500, the water in the inner filtering container 400 and the outer filtering container 500 can be disturbed by the turbulence structure 700 to form a turbulent flow, increasing the impact force of the water flow on the inner filtering container 400 and the outer filtering container 500, thereby improving the cleaning effect of the inner filtering container 400 and the outer filtering container 500 and reducing the cleaning difficulty of the extraction device 001.

[0081] As Figure 1 , Figure 4 and Figure 5 shown, in some embodiments of the present utility model, the turbulence structure 700 includes at least one first turbulence rib 710 provided on the inner filtering container 400 and at least one second turbulence rib 720 provided on the outer filtering container 500.

[0082] In other embodiments of the present utility model, those skilled in the art can also, according to needs, only provide at least one first turbulence rib 710 on the inner filtering container 400, or only provide at least one second turbulence rib 720 on the outer filtering container 500.

[0083] Next, refer to Figures 5 to 7 to describe the inner filtering container 400 in detail.

[0084] As Figures 5 to 7As shown, in some embodiments of the present utility model, the inner filtration container 400 is generally in a barrel-shaped structure, and a plurality of first filtration holes 411 are evenly distributed on the first circumferential side wall 410 of the inner filtration container 400.

[0085] Continuing to refer to Figures 5 to 7 , in some embodiments of the present utility model, at least one first flow disturbing rib 710 is provided on at least one of the inner and outer sides of the first circumferential side wall 410.

[0086] As Figure 6 and Figure 7 shown, in some embodiments of the present utility model, a plurality of first flow disturbing ribs 710 can be provided only on the inner side of the first circumferential side wall 410. The number of the first flow disturbing ribs 710 can specifically be any value from 2 to 12, such as 2, 3, 5, 7, 8, 9, 12, etc.

[0087] Of course, those skilled in the art can also, according to needs, provide a plurality of first flow disturbing ribs 710 only on the outer side of the first circumferential side wall 410, or provide a plurality of first flow disturbing ribs 710 on both the inner and outer sides of the first circumferential side wall 410 respectively.

[0088] When a plurality of first flow disturbing ribs 710 are provided on both the inner and outer sides of the first circumferential side wall 410, the first flow disturbing ribs 710 on the inner and outer sides can be the same or different.

[0089] As Figures 5 to 7 shown, the first flow disturbing rib 710 extends from the bottom end to the top end of the first circumferential side wall 410 to ensure the stirring ability of the first flow disturbing rib 710 on the liquid 004 in the inner filtration container 400, so as to make the liquid 004 form a turbulent flow that flushes the first circumferential side wall 410. Especially when cleaning the inner filtration container 400.

[0090] As Figure 6 shown, the diameter of the inscribed circle D of all the first flow disturbing ribs 710 on the inner side of the first circumferential side wall 410 (as shown by the arc dash line in Figure 6 ) becomes smaller first and then larger from the bottom end to the top end of the first circumferential side wall 410.

[0091] Those skilled in the art can understand that the above arrangement form of the first flow disturbing rib 710 can make the degree of turbulent flow of the water flow on the inner side of the inner filtration container 400 different axially, and thus can cause up-and-down surging, strengthening the cleaning effect of the inner filtration container 400.

[0092] Next, refer to Figure 5 , Figures 8 to 10 to illustrate the outer filtration container 500 in detail.

[0093] As shown in Figure 5 and Figures 8 to 10 shown, at least one second spoiler rib 720 is provided on at least one of the inner and outer sides of the second circumferential side wall 510.

[0094] As shown in Figure 9 and Figure 10 shown, in some embodiments of the present invention, a plurality of second spoiler ribs 720 may be provided only on the inner side of the second circumferential side wall 510. The specific number of the second spoiler ribs 720 may be any value from 2 to 12, such as 2, 3, 5, 7, 8, 9, 12, etc.

[0095] Of course, those skilled in the art may also, according to needs, provide a plurality of second spoiler ribs 720 only on the outer side of the second circumferential side wall 510, or provide a plurality of second spoiler ribs 720 on both the inner and outer sides of the second circumferential side wall 510 respectively.

[0096] When a plurality of second spoiler ribs 720 are provided on both the inner and outer sides of the second circumferential side wall 510 respectively, the second spoiler ribs 720 on the inner and outer sides may be the same or different.

[0097] As shown in Figure 5 and Figures 8 to 10 shown, in some embodiments of the present invention, the second circumferential side wall 510 of the outer filter container 500 inclines outward from the bottom to the top, so that the liquid 004 rises to the top end of the second circumferential side wall 510 under the action of centrifugal force. And, the second spoiler rib 720 extends from the bottom end of the second circumferential side wall 510 to the top end of the second circumferential side wall 510, so that the second spoiler rib 720 adapts to the inclination trend of the outer second circumferential side wall 510.

[0098] As shown in Figure 5 and Figure 10 shown, in some embodiments of the present invention, the outer filter container 500 further includes an annular plate 520, and the annular plate 520 extends from the top end of the second circumferential side wall 510 towards the inner filter container 400 and abuts against the inner filter container 400, so that the liquid 004 in the outer filter container 500 flows back to the inner filter container 400 through the first filter holes 411 under the restriction of the annular plate 520.

[0099] As shown in Figure 4 and Figure 5 shown, in some embodiments of the present invention, the ratio of the height of the second circumferential side wall 510 to the height of the first circumferential side wall 410 is selected from any value in the range of 0.3 to 0.7, so as to reduce the climbing height of the liquid 004 in the outer filter container 500 and reduce the overall height of the centrifugal extractor 001.

[0100] Among them, the ratio of the height of the second circumferential side wall 510 to the height of the first circumferential side wall 410 can specifically be 0.3, 0.4, 0.5, 0.56, 0.6, 0.7, etc.

[0101] As Figure 5 , Figures 8 to 10 shown, in some embodiments of the present utility model, the outer filtration container 500 further includes an inner ring portion 530, a top plate 540, and an outer ring portion 550. The bottom end of the inner ring portion 530 is connected to the annular plate 520, the top end of the inner ring portion 530 is connected to the inner edge of the top plate 540, and the outer edge of the top plate 540 is connected to the top end of the outer ring portion 550.

[0102] As Figure 4 and Figure 5 shown, in the assembled state, the inner ring portion 530 abuts against the first circumferential side wall 410 of the inner filtration container 400 to increase the connection area between the outer filtration container 500 and the inner filtration container 400 and improve the stability of the outer filtration container 500 and the inner filtration container 400 during rotation.

[0103] Furthermore, the inner ring portion 530 and the first circumferential side wall 410 of the inner filtration container 400 can be in interference fit.

[0104] As Figure 4 and Figure 5 shown, in the assembled state, the top plate 540 can abut against the top circumferential edge of the inner filtration container 400 to prevent other substances such as the extract 002 from entering the outer filtration container 500 through the gap between the inner filtration container 400 and the outer filtration container 500.

[0105] As Figure 4 and Figure 5 shown, in the assembled state, the outer ring portion 550 abuts against the liquid storage container 200 to prevent foreign objects from entering the liquid storage container 200 and affecting the taste of the final solution.

[0106] As Figures 8 to 9 shown, in some embodiments of the present utility model, the distribution density of the second filtration holes 511 at the top of the second circumferential side wall 510 is less than the distribution density at the bottom of the second circumferential side wall 510 to prevent the liquid 004 at the top of the second circumferential side wall 510 from flowing out quickly and being unable to accumulate and flow back to the inner filtration container 400.

[0107] Furthermore, the distribution density of the second filtration holes 511 gradually increases from the top side to the bottom side of the second circumferential side wall 510.

[0108] Alternatively, in other embodiments of the present invention, those skilled in the art can also, as needed, arrange all the second filtering holes 511 at the bottom of the second circumferential sidewall 510 to prevent the liquid 004 at the top of the second circumferential sidewall 510 from flowing away and being unable to accumulate and flow back into the inner filtering container 400.

[0109] It should be noted that in the present invention, the top and bottom of the second circumferential sidewall 510 are two parts in the axial direction of the second circumferential sidewall 510, and there is no clear demarcation between them. For example, the part of the second circumferential sidewall 510 shown in Figure 10 above the double-dashed line can be defined as the top of the second circumferential sidewall 510, and the part of the second circumferential sidewall 510 shown in Figure 10 below the double-dashed line can be defined as the bottom of the second circumferential sidewall 510.

[0110] In other embodiments of the present invention, those skilled in the art can also, as needed, make the aperture diameter of the second filtering holes 511 at the top among the multiple second filtering holes 511 smaller than that of the second filtering holes 511 at the bottom. For example, the aperture diameter of the second filtering holes 511 gradually increases from the top side to the bottom side of the second circumferential sidewall 510.

[0111] Furthermore, in some embodiments of the present invention, the ratio of the aperture diameter of the first filtering holes 411 to that of the second filtering holes 511 is greater than 1 and less than or equal to 3, so as to ensure that the flow capacity of all the second filtering holes 511 on the outer filtering container 500 is less than that of all the first filtering holes 411 in the corresponding area of the inner filtering container 400 corresponding to the second circumferential sidewall 510, thereby preventing the liquid 004 in the outer filtering container 500 from being quickly ejected.

[0112] Still further, the ratio of the aperture diameter of the first filtering holes 411 to that of the second filtering holes 511 is greater than 1 and less than or equal to 2.

[0113] Exemplarily, the ratio of the aperture diameter of the first filtering holes 411 to that of the second filtering holes 511 can specifically be 1.1, 1.5, 1.7, 1.9, 2, 2.5, 3, etc.

[0114] Such as Figure 1 、 Figure 4 、 Figure 5 and Figure 11As shown, at least one avoidance groove 602 is provided on the circumferential side wall of the pressing block 600. The avoidance groove 602 is adapted to the first spoiler rib 710 inside the first circumferential side wall 410 to prevent the pressing block 600 from rotating relative to the inner filter container 400. That is, the number of avoidance grooves 602 is not less than the number of the first spoiler ribs 710 inside the first circumferential side wall 410. Thus, through the matching of the first spoiler rib 710 and the avoidance groove 602, the pressing block 600 and the inner filter container 400 rotate synchronously, avoiding the pressing block 600 from wearing the inner filter container 400 and generating debris, which affects the drinking safety of users.

[0115] Furthermore, the avoidance groove 602 and the first spoiler rib 710 can be in clearance fit to facilitate the installation and disassembly of the pressing block 600.

[0116] Next, with reference to Figure 11 and taking the to-be-extracted substance 002 as coffee as an example, the working principle and usage method of the centrifugal extractor 001 of the present utility model will be briefly described. For the convenience of understanding, Figure 11 the spoiler structure 700 is hidden.

[0117] As Figure 11 shown, after the to-be-extracted substance 002 is placed in the inner filter container 400, the motor 310 is started. The motor 310 drives the inner filter container 400 and the outer filter container 500 to rotate, and thus the to-be-extracted substance 002 in the inner filter container 400 generates a centrifugal force and adheres to the first circumferential side wall 410 of the inner filter container 400.

[0118] Continuing to refer to Figure 11 , after adding the liquid 004 (specifically water) to the inner filter container 400, the liquid 004 will also generate a centrifugal force as the inner filter container 400 rotates and passes through the to-be-extracted substance 002, thereby forming a solution in which the target substance 003 in the to-be-extracted substance 002 is dissolved. For the convenience of description, this solution will also be described as the liquid 004 hereinafter.

[0119] Continuing to refer to Figure 11 , as the inner filter container 400 rotates, the liquid 004 in the inner filter container 400 passes through the first filter holes 411 and is thrown out into the outer filter container 500. A part of the liquid 004 in the outer filter container 500 is thrown out into the liquid storage container 200 through the second filter holes 511 (as shown by the dotted line with an arrow at the bottom side in Figure 11 ). Another part of the liquid 004 in the outer filter container 500 climbs along the inclined second circumferential side wall 510 to the annular plate 520 under the action of the centrifugal force and is squeezed back into the inner filter container 400 as the liquid 004 below the annular plate 520 continuously increases (as shown by the dotted line with an arrow at the top side in Figure 11 ), and then enters the next cycle.

[0120] After the extraction of the centrifugal extractor 001 of the present utility model is completed, the liquid 004 in the liquid storage container 200 is discharged through the liquid discharge channel 201.

[0121] In order to prevent the liquid 004 in the liquid storage container 200 from being discharged during the extraction process, those skilled in the art can also, as needed, configure a plug for the liquid discharge channel 201 to close the liquid discharge channel 201 through the plug and remove the plug from the liquid discharge channel 201 when liquid discharge is required.

[0122] In the present utility model, it is possible to determine whether the centrifugal extractor 001 has completed the extraction of the material to be extracted 002 by counting the running time of the motor 310, or by determining whether the concentration of the liquid 004 in the liquid storage container 200 has reached the value set by the user.

[0123] After the centrifugal extractor 001 is used, by making the motor 310 rotate forward and reverse alternately (for example, the forward-reverse stop ratio of the motor 310 is 5:3), the pressing block 600 can vibrate the inner filter container 400 through the cooperation between the avoidance groove 602 and the first turbulence rib 710, so that the compacted material to be extracted 002 in the inner filter container 400 is vibrated and loosened, preventing the material to be extracted 002 from adhering to the inner filter container 400, thus facilitating the user to take out the material to be extracted 002.

[0124] After taking out the material to be extracted 002, the user can pour enough clean water into the inner filter container 400, and then start the motor 310 to make the motor 310 rotate in one direction, or rotate forward and reverse alternately. During the rotation of the first turbulence rib 710 and the second turbulence rib 720 with the inner filter container 400 and the outer filter container 500, the clean water in the inner filter container 400 and the outer filter container 500 will be disturbed and a turbulent flow will be formed. Compared with the laminar flow of the water flow, the turbulent flow has a greater impact on the inner filter container 400 and the outer filter container 500, thereby improving the cleaning effect of the clean water on the inner filter container 400 and the outer filter container 500 and reducing the cleaning difficulty of the extraction device 001.

[0125] Based on the foregoing description, those skilled in the art can understand that the centrifugal extractor 001 of the present utility model not only improves the integrity of the extraction of the material to be extracted 002, but also is convenient for cleaning.

[0126] So far, the technical solutions of the present utility model have been described in combination with multiple embodiments in the foregoing text. However, it is easily understood by those skilled in the art that the protection scope of the present utility model is not limited to these specific embodiments. Without departing from the technical principle of the present utility model, those skilled in the art can split and combine the technical solutions in the above-mentioned various embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc. made within the technical concept and / or technical principle of the present utility model will fall within the protection scope of the present utility model.
