Description

Technical Field

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

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

[0003] The principle of the above extraction method is to dissolve and diffuse the target substances in the extractables such as coffee into the solution by means of molecular diffusion. It not only takes a long time, but also makes the extractables still retain a large amount of target substances after extraction, and the extraction is incomplete, which even affects the taste of the final drinking solution. Summary of the Utility Model

[0004] An object of the utility model is to solve the problem that the existing extraction equipment has poor extraction integrity for the extractables.

[0005] To achieve the above object, the utility model provides a centrifugal extractor, comprising:

[0006] A fuselage;

[0007] A liquid storage container, arranged on the fuselage;

[0008] A driving device, installed on the fuselage;

[0009] A first filtering container, drivingly connected to the driving device to be driven by the driving device to rotate, so as to extract the extractables therein by centrifugation, and to throw the extracted target substances into the liquid storage container;

[0010] A pressing block, slidably arranged in the first filtering container along the rotation axis of the first filtering container to limit the height of the extractables in the first filtering container; the pressing block is configured to be fixed to the peripheral wall of the first filtering container by magnetic attraction to realize the relative fixation of the pressing block and the first filtering container.

[0011] Optionally, the pressing block includes a body and a magnet installed on the body, so that the pressing block is attracted to the peripheral wall of the first filtering container by the magnet.

[0012] Optionally, an annular groove is arranged on the circumferential side wall of the body, and the magnet is embedded in the annular groove.

[0013] Optionally, the magnet is arranged as an annular shape adapted to the annular groove; and / or, the cross-section of the annular groove perpendicular to its extending direction is rectangular.

[0014] Optionally, the pressing block further includes a protective cover sleeved on the circumferential side wall of the body to hide the magnet.

[0015] Optionally, the pressing block is configured as a magnet.

[0016] Optionally, the pressing block is configured to be annular to input the extract to be extracted into the first filtration container through the hollow area of the pressing block.

[0017] Optionally, the top surface of the pressing block is configured as a funnel surface.

[0018] Optionally, the centrifugal extractor further includes a second filtration container disposed outside the first filtration container. The first filtration container includes a first top plate extending outward, and a card slot with a downward opening is provided on the first top plate; the second filtration container includes a second top plate extending outward, and a rib protruding upward is provided on the second top plate, and the rib is embedded in the card slot to fix the first filtration container and the second filtration container together.

[0019] Optionally, the centrifugal extractor further includes a connector fixedly connected to the driving device, and the second filtration container is fixedly connected to the connector.

[0020] Based on the foregoing description, those skilled in the art can understand that in the foregoing technical solution of the present invention, by configuring the first filtration container drivingly connected to the driving device, the first filtration container can perform centrifugal extraction on the extract to be extracted placed therein by rotation, and the target substance after extraction is thrown out into the liquid storage container. During centrifugal extraction, it is easier to throw out the effective substances on the extract to be extracted from the first filtration container. Therefore, the centrifugal extractor of the present invention improves the integrity of the extraction of the extract to be extracted.

[0021] Moreover, the present invention also effectively limits the height of the extract to be extracted in the first filtration container by configuring a pressing block slidably disposed in the first filtration container along the rotation axis of the first filtration container, avoiding uneven thickness of the extract to be extracted attached to the first filtration container and also avoiding the extract to be extracted being thrown out of the first filtration container.

[0022] Moreover, the present invention also fixes the pressing block and the first filtration container relatively by configuring the pressing block to be fixed to the circumferential wall of the first filtration container by magnetic attraction, which enables the user to adjust the height of the pressing block in the first filtration container according to the amount of the extract to be extracted, and also avoids the pressing block shaking or even being thrown out of the first filtration container when the first filtration container rotates.

[0023] Furthermore, by making the pressing block include a body and a magnet installed on the body, the pressing block can be attracted to the peripheral wall of the first filtering container through the magnet, ensuring both sufficient strength of the pressing block and the attraction force between the pressing block and the first filtering container.

[0024] Furthermore, by providing an annular groove on the circumferential side wall of the body, embedding the magnet into the annular groove, and setting the magnet to be annular, the rotational balance during the rotation of the pressing block is ensured.

[0025] Furthermore, by sleeving a protective cover outside the pressing block body to hide the magnet, it effectively avoids the debris generated when the magnet breaks from being mixed into the extract to be extracted and being thrown into the liquid storage container.

[0049] Those skilled in the art should understand that the embodiments described below are only part of the embodiments of the present utility model, rather than all embodiments of the present utility model. These embodiments are intended to explain the technical principles of the present utility model and are 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 should still fall within the protection scope of the present utility model.

[0050] It should be noted that in the description of the present utility model, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inner", "outer", etc., which indicate directions or positional relationships, are based on the directions or positional relationships shown in the drawings. 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 of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0051] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" 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 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 circumstances. For example, the terms "installed", "connected", "coupled" 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] In addition, it should be noted that in the description of the present utility model, the terms "cooling capacity" and "heat quantity" are two descriptions of the same physical state. That is, the higher the "cooling capacity" of a certain target object (such as an evaporator, air, condenser, etc.), the lower the "heat quantity" it has; the lower the "cooling capacity", the higher the "heat quantity". When a certain target object absorbs "cooling capacity", it will release "heat quantity", and when it releases "cooling capacity", it will absorb "heat quantity". A certain target object stores "cooling capacity" or "heat quantity" to keep the current temperature of the target object. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target object (such as an evaporator) will absorb heat while refrigerating.

[0053] Such as Figures 1 to 4As 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, a first filtration container 400, an optional second filtration container 500, and a pressing block 600.

[0054] 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 first filtration container 400, and the second filtration 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 first filtration container 400, and the second filtration 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.

[0055] Among them, the liquid storage container 200 is used to hold the liquid 004 added into the centrifugal extractor 001 or the liquid 004 generated during the operation of the centrifugal extractor 001.

[0056] 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.

[0057] Among them, the circumferential side wall of the first filtration container 400 is denoted as the first circumferential side wall 410 and is provided with a plurality of first filtration holes 411. The first filtration container 400 is arranged in the liquid storage container 200 and is drivingly connected to the driving device 300. The first filtration container 400 is used to perform centrifugal extraction on the extractable substance 002 (such as Figure 12 as shown) placed therein by rotation, and enable the extracted target substance 003 (such as Figure 12 as shown) to pass through the first filtration holes 411.

[0058] Among them, the circumferential side wall of the second filtration container 500 is denoted as the second circumferential side wall 510 and is provided with a plurality of second filtration holes 511. The second filtration container 500 is arranged between the liquid storage container 200 and the first filtration container 400 and is drivingly connected to the driving device 300. The second circumferential side wall 510 can be inclined outward from bottom to top, so that the liquid 004 rises to the top end of the second circumferential side wall 510 under the action of centrifugal force, thereby increasing the effective filtration area of the second circumferential side wall 510 for the liquid 004 and improving the filtration efficiency of the second filtration container 500 for the liquid 004.

[0059] In addition, in other embodiments of the present utility model, those skilled in the art can also omit the second filtration container 500 according to needs. However, in this way, the filtration effect may be reduced and the taste of the final solution may be reduced.

[0060] Among them, the pressing block 600 is slidably arranged in the first filtering container 400 along the rotation axis X of the first filtering container 400 (as Figure 4 shown) to limit the height of the extractable substance 002 in the first filtering container 400. The pressing block 600 is also configured to be fixed to the peripheral wall of the first filtering container 400 by magnetic attraction to achieve relative fixation between the pressing block 600 and the first filtering container 400. The pressing block 600 can also compact the extractable substance 002 in the first filtering container 400 to prevent the extractable substance 002 from being thrown out of the first filtering container 400.

[0061] Furthermore, a feeding hole 601 can be arranged in the middle of the pressing block 600 to facilitate the user to feed the extractable substance 002 and water into the first filtering 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.

[0062] Those skilled in the art can understand that the present utility model configures the first filtering container 400 driven by the driving device 300, so that the first filtering container 400 can perform centrifugal extraction on the extractable substance 002 placed therein by rotation, and the extracted substance can pass through the first filtering holes 411. During centrifugal extraction, it is easier to throw the target substance 003 on the extractable substance 002 out of the first filtering container 400. Therefore, the centrifugal extractor 001 of the present utility model improves the integrity of the extraction of the extractable substance 002.

[0063] Moreover, the present utility model also effectively limits the height of the extractable substance 002 in the first filtering container 400 by configuring the pressing block 600 slidably arranged in the first filtering container 400 along the rotation axis X of the first filtering container 400, avoiding uneven thickness of the extractable substance 002 attached to the first filtering container 400, and at the same time avoiding the extractable substance 002 from being thrown out of the first filtering container 400.

[0064] Moreover, the present utility model also fixes the pressing block 600 to the peripheral wall of the first filtering container 400 by magnetic attraction, so that the pressing block 600 and the first filtering container 400 are relatively fixed together. This can enable the user to adjust the height of the pressing block 600 in the first filtering container 400 according to the amount of the extractable substance 002, and at the same time avoid the pressing block 600 from shaking or even being thrown out of the first filtering container 400 when the first filtering container 400 rotates.

[0065] 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.

[0066] Of course, those skilled in the art can also, according to needs, make the extractant 002 include any other feasible powdery substances, such as soybean powder, mung bean powder, cocoa powder, lemon, etc.

[0067] During the process of the centrifugal extractor 001 of the present utility model extracting the extractant 002, a liquid 004 in which the target substance 003 is dissolved is generated.

[0068] Among them, the target substance 003 can be a substance in the extractant 002 that is soluble in water. The liquid 004 is the liquid substance of the extractant 002 itself or can also 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.

[0069] 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 first filter container 400 and the second filter container 500 through the knob 110.

[0070] 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 first filter container 400 and the second 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 controller adapted to the centrifugal extractor 001, or devices such as a mobile phone or a tablet computer communicatively connected to the centrifugal extractor 001.

[0071] As Figures 1 to 4 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 take down the liquid storage container 200 and clean it. Of course, those skilled in the art can also, according to needs, fixedly connect the liquid storage container 200 to the fuselage 100.

[0072] 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 2As 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, so as to realize 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 clamping groove 421 (not marked in the figure) corresponding to the hanging ear is provided on the fuselage 100. The hanging ear is embedded in the clamping groove 421 to further realize the circumferential fixation of the liquid storage container 200 and the fuselage 100.

[0073] 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.

[0074] 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.

[0075] 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 the driving connection between the driving device 300 and the first filter container 400 and the second 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.

[0076] As Figure 1 、 Figure 2 and Figure 4 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, the motor 310 is fixedly connected to the connector 320 through its rotating shaft, and the connector 320 is fixedly connected to the first filter container 400 and the second filter container 500, so that the motor 310 drives the first filter container 400 and the second filter container 500 to rotate through the connector 320.

[0077] Specifically, a through hole is formed between the top cavity 101 and the bottom cavity 102 of the fuselage 100, and 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.

[0078] 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 this 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.

[0079] 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.

[0080] 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.

[0081] Furthermore, the connector 320 is fixedly connected to the first filter container 400 and the second filter container 500, so that the motor 310 drives the first filter container 400 and the second filter container 500 to rotate synchronously through the connector 320. For example, the connector 320 is riveted, welded or screwed to the second filter container 500, and the first filter container 400 is snap-connected, welded or screwed to the second filter container 500.

[0082] In other embodiments of the present invention, those skilled in the art can also, according to needs, set the connector 320 into 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 first filter container 400 and the second 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.

[0083] In addition, in other embodiments of the present invention, those skilled in the art can also, according to needs, set the driving device 300 into any other feasible form, such as making the driving device 300 only include the motor 310, and directly fixedly connecting the rotating shaft of the motor 310 to at least one of the first filter container 400 and the second filter container 500. When the rotating shaft of the motor 310 is only fixedly connected to one of the first filter container 400 and the second filter container 500, connect the one to the other of the first filter container 400 and the second filter container 500 through a connection method such as welding, riveting, snap connection, bolt connection, etc.

[0084] Such as Figure 5As shown, in some embodiments of the present utility model, the first filtering container 400 further includes a first top plate 420 extending outward, and a card slot 421 with an opening facing downward is provided on the first top plate 420.

[0085] It can be seen from Figure 5 that the first top plate 420 is located on the top side of the first circumferential side wall 410, the card slot 421 is an annular slot, and can be formed by a stamping process.

[0086] Continuing to refer to Figure 5 , in some embodiments of the present utility model, the first filtering container 400 may further include a first bottom plate 430 located at the bottom side of the first circumferential side wall 410 to prevent the extract 002 in the first filtering container 400 from leaking out.

[0087] As Figure 6 shown, in some embodiments of the present utility model, the second filtering container 500 further includes an inner ring portion 530, a second top plate 540, an outer ring portion 550, and a second bottom plate 560. 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 second top plate 540, the outer edge of the second top plate 540 is connected to the top end of the outer ring portion 550, and the second bottom plate 560 is located at the bottom side of the second circumferential side wall 510 and is connected to the second circumferential side wall 510.

[0088] Continuing to refer to Figure 6 , in some embodiments of the present utility model, the second bottom plate 560 is provided with riveting holes 561 so that the second filtering container 500 is riveted to the connector 320 through the riveting holes 561 by means of rivets. Of course, those skilled in the art can also, according to needs, use other connection methods to fixedly connect the second filtering container 500 and the connector 320 together. For details, please refer to the description of the connector 320 part above.

[0089] As Figure 4 and Figure 7 shown, in the assembled state, the inner ring portion 530 abuts against the first circumferential side wall 410 of the first filtering container 400 to increase the connection area between the second filtering container 500 and the first filtering container 400 and improve the stability of the second filtering container 500 and the first filtering container 400 during rotation.

[0090] Furthermore, the inner ring portion 530 and the first circumferential side wall 410 of the first filtering container 400 can be in interference fit.

[0091] As Figure 6 shown, a rib 541 protruding upward is provided on the second top plate 540 of the second filtering container 500, and the rib 541 is adapted to the card slot 421 on the first filtering container 400.

[0092] Continue to refer to Figure 4 and Figure 7 , in some embodiments of the present utility model, the rib 541 is embedded in the card slot 421 to fix the first filter container 400 and the second filter container 500 together.

[0093] In some embodiments of the present utility model, the first bottom plate 430 of the first filter container 400 and the second bottom plate 560 of the second filter container 500 may or may not be in contact.

[0094] As Figures 1 to 4 shown, in some embodiments of the present utility model, the pressing block 600 is arranged in a ring shape to put the extractant 002 into the first filter container 400 through the hollow area of the pressing block 600. This hollow area is the feeding hole 601 described above.

[0095] Furthermore, the top surface of the pressing block 600 is arranged as a funnel surface, so that the extractant 002 on the top surface of the pressing block 600 slides towards the feeding hole 601 under the action of the funnel surface.

[0096] Correspondingly, those skilled in the art can also, according to needs, arrange the bottom surface of the pressing block 600 as a funnel surface to facilitate the installation of the pressing block 600 by the user without the need to distinguish the front and back of the pressing block 600.

[0097] As Figures 7 to 10 shown, in some embodiments of the present utility model, the pressing block 600 includes a body 610 and a magnet 620 installed on the body 610, so that the pressing block 600 is attracted to the peripheral wall of the first filter container 400 through the magnet 620.

[0098] Among them, an annular groove 611 is arranged on the circumferential side wall of the body 610, and the cross section of the annular groove 611 perpendicular to its extending direction can be rectangular. Of course, those skilled in the art can also, according to needs, arrange this cross section into any feasible shape such as C-shaped, U-shaped, semi-circular, etc.

[0099] Among them, the magnet 620 is arranged as an annular shape adapted to the annular groove 611 and is embedded in the annular groove 611.

[0100] For the convenience of installing the magnet 620, those skilled in the art can also, according to needs, arrange the body 610 into two parts, and these two parts can be connected together by means of threads, screws, snap connections, etc. The annular groove 611 is jointly defined by these two parts. When installing the magnet 620, first install the magnet 620 on one of the two parts, and then fix the other part to this one part, so as to clamp the magnet 620 between these two parts.

[0101] In addition, in other embodiments of the present utility model, those skilled in the art can also, as needed, set the annular groove 611 and the magnet 620 into any other feasible shapes. Specifically as follows:

[0102] Example 1: An annular groove 611 is provided on the circumferential side wall of the body 610. There are multiple magnets 620, and they are evenly distributed in the annular groove 611.

[0103] Example 2: An annular groove 611 is provided on the circumferential side wall of the body 610. The magnet 620 is composed of two semi-circular members, and both are arranged in the annular groove 611.

[0104] Example 3: Multiple equally spaced grooves are provided on the circumferential side wall of the body 610, and a magnet 620 is respectively embedded in each groove.

[0105] In the present utility model, the magnet 620 can be any feasible magnet such as an alnico magnet, a ferrite magnet, a neodymium iron boron magnet, etc.

[0106] In the present utility model, the body 610 can be made of materials such as stainless steel, alloy, organic materials, etc.

[0107] Of course, those skilled in the art can also, as needed, set the pressing block 600 as a whole and set the pressing block 600 as the magnet 620.

[0108] In the present utility model, the first filtration container 400 is made of a material that can be attracted by the magnet 620, such as iron, stainless steel, etc.

[0109] As Figure 11 shown, in some other embodiments of the present utility model, those skilled in the art can also, as needed, make the pressing block 600 further include a protective cover 630, and sleuth the protective cover 630 on the circumferential side wall of the body 610 to hide the magnet 620.

[0110] Those skilled in the art can understand that the protective cover 630 effectively prevents the debris generated when the magnet 620 breaks from being mixed into the extractant 002 and being thrown into the liquid storage container 200.

[0111] Next, with reference to Figure 11 and Figure 12 and taking the extractant 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, the turbulence structure is hidden in the figure.

[0112] As Figure 11 and Figure 12As shown, after the extract 002 to be extracted is placed in the first filtration container 400, the user can adjust the height of the pressing block 600 according to the amount of the extract 002. Then, the motor 310 is started. The motor 310 drives the first filtration container 400 and the second filtration container 500 to rotate, and thus causes the extract 002 in the first filtration container 400 to generate a centrifugal force and adhere to the first circumferential side wall 410 of the first filtration container 400.

[0113] Continue to refer to Figure 11 and Figure 12 After adding the liquid 004 (specifically water) to the first filtration container 400, the liquid 004 will also generate a centrifugal force as the first filtration container 400 rotates, and pass through the extract 002, thereby forming a solution in which the target substance 003 in the extract 002 is dissolved. For the convenience of description, this solution will also be described as the liquid 004 hereinafter.

[0114] Continue to refer to Figure 11 and Figure 12 As the first filtration container 400 rotates, the liquid 004 in the first filtration container 400 passes through the first filtration holes 411 and is thrown out into the second filtration container 500 (as shown by the dotted line with an arrow at the bottom side in Figure 12 ). The liquid 004 in the second filtration container 500 is thrown out into the liquid storage container 200 via the second filtration holes 511. During this process, a part of the liquid 004 in the second filtration container 500 will climb upward along the inclined second circumferential side wall 510 under the action of the centrifugal force and evenly spread on the entire second circumferential side wall 510, thereby improving the filtration performance of the second filtration container 500.

[0115] When the centrifugal extractor 001 of the present utility model finishes extraction, the liquid 004 in the liquid storage container 200 is discharged via the liquid discharge channel 201.

[0116] 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.

[0117] In the present utility model, it is possible to determine whether the centrifugal extractor 001 has completed the extraction of the extract 002 by counting the running time of the motor 310, or it is also possible to determine whether the centrifugal extractor 001 has completed the extraction of the extract 002 by determining whether the concentration of the liquid 004 in the liquid storage container 200 has reached the value set by the user.

[0118] So far, the technical solutions of the present utility model have been described in combination with multiple embodiments of the foregoing. However, it is easy for those skilled in the art to understand 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.

[0119] Finally, it should be noted that in the present utility model, the term "connected" means fluid connection to allow a fluid (such as air, liquid) to flow between two components that are connected to each other. And this "connection" can be such that the fluid flows between the two components that are connected to each other without leakage, or it can be such that the fluid flows between the two components that are connected to each other with a little leakage.
