Description

Technical Field

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

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

[0003] The principle of the above extraction method is to make the target substance in the coffee waiting to be extracted dissolve and diffuse into the solution by molecular diffusion. It is not only time-consuming, but also causes the extract to still retain a large amount of target substance after extraction, resulting in incomplete extraction and even affecting the taste of the final drinking solution. Utility Model Content

[0004] One purpose of the present invention is to solve the problem that the existing extraction equipment has poor extraction integrity.

[0005] Another object of the present invention is to reduce the operating noise of the centrifugal extractor.

[0006] To achieve the above-mentioned object, the present invention provides a centrifugal extractor, comprising:

[0007] liquid storage container;

[0008] a driving device, fixed relatively to the liquid storage container;

[0009] an inner filter container, disposed in the liquid storage container and drivingly connected to the driving device, so that the inner filter container extracts the substance to be extracted therein by centrifugation;

[0010] At least two counterweights are fixedly connected to or integrally formed with the inner filter container to improve the dynamic balance of the inner filter container, thereby reducing the operating noise of the centrifugal extractor.

[0011] Optionally, the at least two counterweights are arranged on the top of the inner filter container.

[0012] Optionally, the inner filter container includes a closing structure located at the top thereof, and the at least two counterweights are arranged on the closing structure.

[0013] Optionally, the at least two balancing weights are distributed at equal intervals along the circumference of the inner filter container; and / or the cross section of the balancing weight is I-shaped, so that the balancing weight is connected to the inner filter container through its two opposite side plates.

[0014] Optionally, the centrifugal extractor further comprises an outer filter container arranged outside the inner filter container, and the outer filter container is coaxially fixed with the inner filter container so that the outer filter container and the inner filter container rotate synchronously.

[0015] Optionally, the counterweight block abuts against the outer filter container to prevent the outer filter container and the inner filter container from generating relative displacement or deformation in the radial direction.

[0016] Optionally, the centrifugal extractor further includes a balancing ring fixedly connected to or integrally formed with the outer filter container to improve the dynamic balance of the outer filter container, thereby reducing the operating noise of the centrifugal extractor.

[0017] Optionally, the balancing ring defines an annular cavity, and the annular cavity is filled with a balancing liquid.

[0018] Optionally, the balance ring is arranged on the top side of the inner filter container.

[0019] Optionally, the centrifugal extractor further comprises a pressing block, which is removably mounted in the outer filter container, and the pressing block abuts against the inner filter container via its bottom surface and abuts against the balance ring via its circumferential surface.

[0020] Based on the foregoing description, those skilled in the art will appreciate that, in the aforementioned technical solution of the present invention, by configuring an inner filter container driven by a driving device, the inner filter container can be rotated to centrifugally extract the material to be extracted therein, and the extracted target substance is ejected from the inner filter container. During centrifugal extraction, the target substance on the material to be extracted is more easily ejected from the inner filter container, thereby improving the completeness of the extraction of the material to be extracted by the centrifugal extraction machine of the present invention.

[0021] Furthermore, the present invention improves the dynamic balance of the inner filter container by configuring at least two counterweights fixedly connected to or integrally formed with the inner filter container, thereby reducing the operating noise of the centrifugal extractor.

[0022] Furthermore, since the inner filter container has an uneven distribution of the extract therein, the eccentricity amplitude will gradually increase from the bottom to the top. The present invention can effectively weaken or even avoid the eccentric vibration of the top of the inner filter container by arranging at least two counterweights at the top of the inner filter container.

[0023] Furthermore, by distributing at least two counterweights at equal intervals along the circumference of the inner filter container, the center of mass of all counterweights can coincide with the rotation axis of the inner filter container as much as possible, thereby increasing the rotational inertia of the inner filter container while effectively avoiding eccentricity during rotation of the inner filter container.

[0024] Furthermore, by configuring the cross-section of the counterweight to be I-shaped and connecting the counterweight to the inner filter container via its two opposing side panels, not only is the connection between the counterweight and the inner filter container facilitated, but a channel is also formed between the two side panels of the counterweight, particularly between the counterweight and the inner filter container. The counterweight continuously divides the air in this channel, and the inertia of the air flowing into the channel limits the radial displacement of the counterweight, thereby further reducing the eccentric vibration of the inner filter container and achieving unexpected technical benefits.

[0025] Furthermore, by arranging an outer filter container outside the inner filter container, the centrifugal extractor can perform double filtration on the extract through the inner filter container and the outer filter container.

[0026] Furthermore, by making the counterweight block abut against the outer filter container, relative displacement or deformation of the outer filter container and the inner filter container in the radial direction is effectively prevented, thereby improving the connection strength between the inner filter container and the outer filter container.

[0027] Furthermore, by configuring a balancing ring that is fixedly connected to or integrally formed with the outer filter container, the dynamic balance of the outer filter container is improved, and the operating noise of the centrifugal extractor is effectively controlled.

[0028] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0057] Those skilled in the art should understand that the embodiments described below are only a portion of the embodiments of the present invention, rather than all of the embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

Therefore, it should not be understood as limiting the present utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0059] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" 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 a direct connection, an indirect connection through an intermediate medium, or a communication between the two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. For example, the terms "install", "connect", "connect", and "fix", unless otherwise specified, can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, plug-in connection, riveting, welding, and clamping.

[0060] like Figures 1 to 5 As shown, in some embodiments of the present invention, the centrifugal extractor 001 innovatively uses centrifugal extraction technology and includes an optional body 100, a liquid storage container 200, a driving device 300, an inner filter container 410, an optional outer filter container 420, an optional balance ring 500, an optional pressure block 600 and at least two counterweight blocks 700.

[0061] The housing 100 defines a top cavity 101 and a bottom cavity 102. The top cavity 101 is used to accommodate the liquid storage container 200, the inner filter container 410, and the outer filter container 420, while the bottom cavity 102 is used to accommodate the drive device 300. Of course, as needed, those skilled in the art may also configure the housing 100 to any other feasible shape, such as a hollow barrel-shaped member, provided that the liquid storage container 200, the drive device 300, the inner filter container 410, and the outer filter container 420 can be accommodated. Alternatively, those skilled in the art may also omit the housing 100 as needed. That is, as needed, those skilled in the art may also omit the housing 100 or integrate the housing 100 with the liquid storage container 200, provided that the liquid storage container 200, the drive device 300, the inner filter container 410, and the outer filter container 420 can be relatively fixed.

[0062] The liquid storage container 200 is used to hold the liquid 004 (such as Figure 16 as shown), or the liquid 004 produced during the operation of the centrifugal extractor 001.

[0063] The driving device 300 is relatively fixed to the liquid storage container 200 , and can be specifically fixedly connected to the body 100 .

[0064] The inner filter container 410 is disposed in the liquid storage container 200 and is connected to the driving device 300 so that the inner filter container 410 extracts the extract 002 (e.g. Figure 16As shown) for centrifugal extraction, and the extracted target substance 003 (as shown Figure 16 The small triangle shown in the figure is thrown out from the inner filter container 410 under the action of centrifugal force.

[0065] The outer filter container 420 is disposed outside the inner filter container 410 and is coaxially fixed with the inner filter container 410 so that the outer filter container 420 and the inner filter container 410 rotate synchronously, thereby performing a double filtration on the extract 002. Furthermore, those skilled in the art may also omit the outer filter container 420 as needed.

[0066] The balance ring 500 is fixed relative to the outer filter container 420 to improve the dynamic balance of the outer filter container 420, thereby reducing the operating noise of the centrifugal extractor 001. In addition, those skilled in the art may also omit the setting of the balance ring 500 as needed.

[0067] The pressing block 600 is detachably mounted in the inner filter container 410 to compress the material to be extracted 002 in the inner filter container 410 to prevent the material to be extracted 002 from being thrown out of the inner filter container 410. Furthermore, those skilled in the art may omit the pressing block 600 or configure the pressing block 600 as a cover, a stopper, or other component as needed.

[0068] Among them, at least two counterweights 700 are fixedly connected to or integrally formed with the inner filter container 410 to improve the dynamic balance of the inner filter container 410, thereby reducing the operating noise of the centrifugal extractor 001.

[0069] Those skilled in the art will appreciate that, by configuring the inner filter container 410 to be driven by the driving device 300, the inner filter container 410 can rotate to centrifugally extract the object to be extracted 002 placed therein, and eject the extracted target substance 003 from the inner filter container 410. During centrifugal extraction, the target substance 003 on the object to be extracted 002 is more easily ejected from the inner filter container 410, thereby improving the completeness of the extraction of the object to be extracted 002 by the centrifugal extractor 001 of the present invention.

[0070] Furthermore, the present invention improves the dynamic balance of the inner filter container 410 by configuring at least two counterweights 700 that are fixedly connected to or integrally formed with the inner filter container 410 , thereby reducing the operating noise of the centrifugal extractor 001 .

[0071] It should be noted that, in the present invention, the object to be extracted 002 includes coffee powder and / or tea powder. For example, the object to be extracted 002 can be coffee powder or tea powder, or a mixture of coffee powder and tea powder.

[0072] Of course, those skilled in the art may also make the extract 002 include any other feasible powdered substances as needed, such as soybean powder, mung bean powder, cocoa powder, lemon, etc.

[0073] The centrifugal extractor 001 of the present invention produces a solution of the target substance 003 (such as Figure 16 Liquid 004 (shown in the small triangle).

[0074] Target substance 003 can be a water-soluble substance in the object to be extracted 002. Liquid 004 is the liquid substance of the object to be extracted 002 itself, or it can be water. The water can be hot, room temperature, or cold water, and its composition can be pure water, tap water, mineral water, or water dissolved with a specific substance (e.g., sugar, milk, flavoring, etc.).

[0075] like Figures 1 to 3 As shown, in some embodiments of the present invention, a knob 110 may be further provided on the body 100 to adjust the rotation speeds of the inner filter container 410 and the outer filter container 420 .

[0076] Furthermore, in other embodiments of the present invention, those skilled in the art may, as needed, omit the knob 110 and control the rotational speeds of the inner and outer filter containers 410 and 420 using other buttons or other devices. These other buttons may be physical buttons on the centrifugal extractor 001 or virtual buttons displayed on a display screen on the centrifugal extractor 001. These other devices may be remote controls compatible with the centrifugal extractor 001, or mobile phones, tablets, and other devices connected to the centrifugal extractor 001.

[0077] like Figures 1 to 4 As shown, in some embodiments of the present invention, the liquid storage container 200 is placed in the top cavity 101 of the body 100 and can be detachably connected to the body 100 to facilitate the user to remove and clean the liquid storage container 200. Of course, those skilled in the art can also make the liquid storage container 200 fixedly connected to the body 100 as needed.

[0078] When the liquid storage container 200 is detachably connected to the body 100, the liquid storage container 200 and the body 100 are provided with a rotation-stopping structure to prevent the liquid storage container 200 from rotating relative to the body 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 body 100. The protruding structure is inserted into the slot, thereby achieving the circumferential θ (as shown in FIG. Figure 4The liquid storage container 200 may also be provided with a lug (not labeled in the figure) on the side away from the protruding structure. The body 100 is provided with a slot (not labeled in the figure) corresponding to the lug, and the lug is inserted into the slot to further achieve circumferential θ fixation of the liquid storage container 200 and the body 100.

[0079] When the liquid storage container 200 is fixedly connected to the body 100, the two can be fixedly connected together by fixing components, structures or materials such as screws, buckles, and glue.

[0080] like Figures 1 to 4 As shown, in some embodiments of the present invention, 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 .

[0081] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the bottom wall of the liquid storage container 200 is provided with an escape hole 202 to avoid the driving device 300, thereby ensuring the driving connection between the driving device 300 and the inner filter container 410 and the outer filter container 420. The liquid storage container 200 is also provided with an annular baffle 210 extending from the bottom wall to the top side to prevent the liquid 004 in the liquid storage container 200 from flowing out of the escape hole 202.

[0082] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the driving device 300 includes a motor 310 and a connector 320. The motor 310 is fixedly connected to the body 100 via its housing, and the motor 310 is fixedly connected to the connector 320 via its rotating shaft. The connector 320 is fixedly connected to the inner filter container 410 and the outer filter container 420, so that the motor 310 drives the inner filter container 410 and the outer filter container 420 to rotate through the connector 320.

[0083] Specifically, a through hole is formed between the top cavity 101 and the bottom cavity 102 of the body 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 .

[0084] The connector 320 can have any feasible structure, such as a plate-like structure, a columnar structure, a Y-shaped structure, or a triangular structure. The connector 320 is provided with a shaft hole (not marked in the figure) that matches the shaft of the motor 310, so that the connector 320 and the shaft of the motor 310 are fixedly connected through the shaft hole. Alternatively, the connector 320 is provided with a connecting shaft, which is fixedly connected to the shaft of the motor 310 via a coupling.

[0085] Alternatively, those skilled in the art may also connect the connector 320 and the rotating shaft of the motor 310 together using any other feasible connection method as needed, such as welding, bolt connection, flange connection, etc.

[0086] Alternatively, those skilled in the art may also make the connector 320 detachably connected to the rotating shaft of the motor 310 as needed, so that the connector 320 can be removed together with the detachable liquid storage container 200 .

[0087] Furthermore, the connector 320 is fixedly connected to the inner filter container 410 and the outer filter container 420, so that the motor 310 drives the inner filter container 410 and the outer filter container 420 to rotate synchronously through the connector 320. For example, the connector 320 is welded or screwed to the inner filter container 410 and the outer filter container 420.

[0088] In other embodiments of the present invention, those skilled in the art may also configure the connector 320 as two synchronously rotatable and detachably connected parts, with one part fixedly connected to the rotating shaft of the motor 310 and the other part fixedly connected to the inner filter container 410 and the outer filter container 420, as needed. For example, the two parts of the connector 320 are each provided with a protruding tooth at one end adjacent to each other, so that the two parts are engaged together through the two protruding teeth, thereby achieving circumferential θ fixation of the two parts.

[0089] In addition, in other embodiments of the present invention, those skilled in the art may also set the drive device 300 to any other feasible form as needed, for example, the drive device 300 only includes the motor 310, and the rotating shaft of the motor 310 is directly fixedly connected to the inner filter container 410 and the outer filter container 420.

[0090] from Figure 4 and Figure 5As can be seen, in some embodiments of the present invention, the bottom of the outer filter container 420 is fixedly connected to the drive device 300 (specifically, the connector 320). This fixed connection can be any feasible connection method, such as welding, screw connection, riveting, etc. In addition, the bottom of the inner filter container 410 is also fixedly connected to the bottom of the outer filter container 420. This fixed connection can be any feasible connection method, such as welding, screw connection, riveting, etc.

[0091] from Figure 4 and Figure 5 It can be seen that in some embodiments of the present invention, the balance ring 500 is set on the top of the outer filter container 420, so that the outer filter container 420 away from the top of the driving device 300 has better dynamic balance under the action of the balance ring 500.

[0092] In this way, and given that the bottom of the outer filter container 420 is secured by the connector 320, both the top and bottom of the outer filter container 420 maintain good dynamic balance. Consequently, even if the material to be extracted 002 within the inner filter container 410 is unevenly distributed, or eccentric, the impact on the dynamic balance of the outer and inner filter containers 420 and 410 is minimal. Therefore, the configuration of the balance ring 500 ensures that the center of mass of the inner and outer filter containers 410, 420, and the material to be extracted 002 substantially coincide with, or are very close to, the rotational axes of the inner and outer filter containers 410 and 420.

[0093] like Figures 4 to 7 As shown, in some embodiments of the present invention, a closing structure 411 is provided on the top of the inner filter container 410 to support the pressing block 600 , thereby preventing the pressing block 600 from falling into the inner filter container 410 .

[0094] like Figure 6 As shown, in some embodiments of the present invention, there may be four balancing weights 700 , and the balancing weights 700 are disposed on the top of the inner filter container 410 , specifically on the closing structure 411 .

[0095] It is understood by those skilled in the art that, when the extract 002 is unevenly distributed in the inner filter container 410, the eccentricity amplitude will gradually increase from the bottom to the top. The present invention can effectively weaken or even avoid the eccentric vibration of the top of the inner filter container 410 by setting the counterweight block 700 at the top of the inner filter container 410.

[0096] In some embodiments of the present invention, the counterweight 700 and the inner filter container 410 may be fixed together in any feasible manner, such as welding, riveting, clamping, bonding, etc.

[0097] from Figure 6 As can be seen in some embodiments of the present invention, all the balancing weights 700 are distributed at equal intervals along the circumference θ of the inner filter container 410, so that the center of mass of all the balancing weights 700 is aligned with the rotation axis of the inner filter container 410 (with the rotation axis of the inner filter container 410). Figure 4 The lines parallel to the central axis z) can overlap as much as possible, thereby increasing the rotational inertia of the inner filter container 410 while effectively avoiding eccentricity when the inner filter container 410 rotates.

[0098] Alternatively, those skilled in the art may, as needed, arrange the counterweights 700 after detecting the center of mass of the inner filter container 410. In this way, although the counterweights 700 may not be evenly spaced, the center of mass of the inner filter container 410 and the counterweights 700 will be nearly aligned with the rotation axis of the inner filter container 410.

[0099] like Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, in some embodiments of the present invention, an annular sink 421 is provided on the top of the outer filter container 420 , and the balance ring 500 is embedded in the sink 421 and fixed relative to the outer filter container 420 .

[0100] Furthermore, the outer filter container 420 and the balance ring 500 can be fixed together by interference fit. Alternatively, those skilled in the art can also fix the outer filter container 420 and the balance ring 500 together by any other feasible method as needed, such as welding, clamping, bonding, etc.

[0101] like Figure 8 and Figure 9 As shown, in some embodiments of the present invention, the outer filter container 420 includes a neck 422 located at the bottom side of the sink 421 , a filter portion 423 located at the bottom side of the neck 422 , and a stopper 424 located at the top side of the sink 421 .

[0102] like Figures 4 to 7 As shown, in some embodiments of the present invention, the inner filter container 410 is disposed within the filter portion 423, and the closing structure 411 of the inner filter container 410 is aligned with the neck 422 of the outer filter container 420. Furthermore, the counterweight 700 can abut against the outer filter container 420 to prevent relative displacement or deformation between the outer filter container 420 and the inner filter container 410 in the radial direction r.

[0103] like Figure 8 and Figure 9As shown, in some embodiments of the present invention, the filter portion 423 can be set to a conical structure with a larger top and a smaller bottom, so that the liquid 004 moves upward along the circumferential wall of the filter portion 423 under the action of centrifugal force, thereby increasing the filtering area of ​​the filter portion 423.

[0104] like Figure 4 As shown, in some embodiments of the present invention, the liquid storage container 200 is provided with an inner edge extending inward (not marked in the figure), and the outer edge of the stop portion 424 on the radial direction r can be located on the bottom side of the inner edge to prevent the liquid 004 in the liquid storage container 200 from being thrown out.

[0105] like Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, in some embodiments of the present invention, at least one disrupting rib 425 is further provided on the inner side of the filter portion 423 to disrupt the liquid 004 in contact with the disrupting rib 425. The number of the disrupting ribs 425 can be 1, 2, 3, 6, 7, 8, 12, etc.

[0106] Of course, those skilled in the art may also provide multiple spoiler ribs 425 on the outside of the filter portion 423 , or provide multiple spoiler ribs 425 on both the inside and outside of the filter portion 423 as needed.

[0107] Furthermore, in some embodiments of the present invention, the aperture of the filter hole (not marked in the figure) on the inner filter container 410 can be larger than the aperture of the filter hole (not marked in the figure) on the outer filter container 420, so that the flow capacity of the filter part 423 of the outer filter container 420 is smaller than the flow capacity of the inner filter container 410, thereby preventing the liquid 004 in the outer filter container 420 from being quickly thrown out.

[0108] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the pressing block 600 is configured in a ring shape so that the object to be extracted 002 (as described above) can be put into the inner filtration container 410 through the hollow area of ​​the pressing block 600 .

[0109] from Figure 1 、 Figure 2 、 Figure 4 and Figure 5As can be seen in the figure, in some embodiments of the present invention, the thickness of the pressing block 600 gradually decreases from the outside to the inside, and the two opposing annular surfaces of the pressing block 600 are both configured as funnel surfaces, so that the extract 002 placed on the top surface of the pressing block 600 slides down the funnel surfaces under the action of its own gravity into the inner filter container 410. At the same time, by configuring the two opposing annular surfaces of the pressing block 600 as funnel surfaces, the user does not need to distinguish the front and back of the pressing block 600 when installing it, which is convenient for the user.

[0110] like Figure 10 and Figure 11 As shown, in some embodiments of the present invention, the balancing ring 500 defines an annular cavity 501, and the annular cavity 501 is filled with a balancing liquid 550. In this way, the material of the balancing ring 500 is saved and the overall weight of the balancing ring 500 is ensured.

[0111] In the present invention, the balancing liquid 550 can be any suitable substance, such as pure water, salt water, or oil. Those skilled in the art will appreciate that salt water can lower the freezing point of the balancing liquid 550, thereby enabling the balancing liquid 550 to operate at a lower ambient temperature and preventing the balancing liquid 550 from bursting the balancing ring 500 due to operation at a lower ambient temperature.

[0112] like Figure 11 As shown, in some embodiments of the present invention, the balance ring 500 is provided with an annular rib 530 in the annular cavity 501 to separate the annular cavity 501 into an inner annular cavity 5011 and an outer annular cavity 5012 .

[0113] It will be understood by those skilled in the art that the inner annular cavity 5011 and the outer annular cavity 5012 enable the balancing liquid 550 to be evenly distributed in the inner annular cavity 5011 and the outer annular cavity 5012, thereby preventing the balancing liquid 550 from being affected by centrifugal force when the balance ring 500 rotates rapidly and being concentrated on the outer side of the annular cavity 501, thereby causing the outer wall of the annular cavity 501 to be prone to leakage due to excessive pressure.

[0114] from Figure 11 As can be seen in the figure, there is a gap between the inner annular cavity 5011 and the outer annular cavity 5012, so that the balancing liquid 550 can flow in the inner annular cavity 5011 and the outer annular cavity 5012, thereby being evenly distributed in the inner annular cavity 5011 and the outer annular cavity 5012.

[0115] like Figure 11 As shown, in some embodiments of the present invention, the balancing ring 500 is provided with at least one water-repelling rib 540 in the inner ring cavity 5011 and / or the outer ring cavity 5012 , so that the balancing ring 500 drives the balancing liquid 550 to rotate through the water-repelling rib 540 .

[0116] It can be understood by those skilled in the art that, under the action of the water-repellent rib 540, the balancing liquid 550 first partially starts to rotate and then gradually rotates completely, thereby reducing the load on the inner filter container 410, the outer filter container 420 and the balance ring 500 when they first start to rotate, thereby reducing the starting power of the drive device 300.

[0117] like Figures 10 to 13 As shown, in some embodiments of the present invention, the balance ring 500 includes an upper annular shell 510 with an opening facing downward and a lower annular shell 520 with an opening facing upward. The upper annular shell 510 and the lower annular shell 520 are sealed together to define an annular cavity 501 .

[0118] The upper annular shell 510 and the lower annular shell 520 can be sealed together by any feasible means such as welding, threaded connection, etc.

[0119] Furthermore, although not shown in the figures, those skilled in the art may also, as needed, provide a filling hole in at least one of the upper annular shell 510 and the lower annular shell 520 to allow the balancing liquid 550 to be filled into the annular cavity 501 through the filling hole. Furthermore, a plug may be provided for the filling hole. For example, the filling hole is configured as a threaded hole, and the plug is configured as a screw plug to seal the threaded hole.

[0120] In addition, under the premise of being able to be filled with the balancing liquid 550 , those skilled in the art may also configure the balancing ring 500 to any other feasible form, such as an integrally made rubber ring, as needed.

[0121] like Figures 11 to 13 As shown, in some embodiments of the present invention, the annular rib 530 includes an upper annular rib 531 disposed in the upper annular shell 510 and an upper annular rib 532 disposed in the lower annular shell 520. Furthermore, a gap is provided between the ends of the upper annular rib 531 and the upper annular rib 532 that are close to each other to ensure that the inner annular cavity 5011 and the outer annular cavity 5012 are connected.

[0122] It will be understood by those skilled in the art that when the upper annular shell 510 and the lower annular shell 520 are squeezed relatively close to each other, the upper annular rib 531 and the upper annular rib 532 can also abut against each other to prevent excessive deformation of the upper annular shell 510 and the lower annular shell 520, thereby improving the structural strength of the balance ring 500.

[0123] like Figures 11 to 13 As shown, in some embodiments of the present invention, the water-repellent rib 540 is disposed in the lower annular shell 520 so that the balancing liquid 550 rotates sequentially from bottom to top when the balancing ring 500 rotates.

[0124] like Figure 11 and Figure 13 As shown, in some embodiments of the present invention, in the radial direction r of the lower annular shell 520 , the height of the water-repellent rib 540 may gradually decrease toward the direction approaching the upper annular rib 532 .

[0125] Those skilled in the art will appreciate that the provision of the water-repellent rib 540 enhances the structural strength of the lower annular shell 520 , and in particular, in conjunction with the upper annular rib 532 , can effectively prevent the lower annular shell 520 from deforming.

[0126] like Figure 14 and Figure 15 As shown, in some embodiments of the present invention, the cross section of the counterweight 700 can be I-shaped and include two opposite side panels 710 and a connecting plate 720 located between the two side panels 710. The counterweight 700 defines a channel 701 through its side panels 710 and the connecting plate 720.

[0127] Return to view Figure 6 The counterweight 700 can be connected to the inner filter container 410 via its two opposing side panels 710. This not only facilitates the connection between the counterweight 700 and the inner filter container 410 and reduces the contact area between them, but also allows the counterweight 700 to continuously divide the air through its channels 701. The air flowing into the channels 701, under its own inertia, limits the radial excursion r of the counterweight 700, further reducing the eccentric vibration of the inner filter container 410, achieving unexpected technical benefits.

[0128] Furthermore, although not shown in the figures, in some embodiments of the present invention, the counterweight block 700 can be made of metal, for example, the counterweight block 700 can be an iron block, a copper block, a stainless steel block, etc.

[0129] Refer to the following Figure 16 Taking the case where the object to be extracted 002 is coffee as an example, the working principle and usage of the centrifugal extraction machine 001 of the present invention will be briefly described. Figure 16 The filtering holes on the inner filtering container 410 are hidden in the figure to facilitate intuitive observation by those skilled in the art.

[0130] like Figure 16 As shown, after the object to be extracted 002 is placed in the inner filter container 410, the motor 310 is started. The motor 310 drives the inner filter container 410 and the outer filter container 420 to rotate in the forward direction, thereby generating centrifugal force on the object to be extracted 002 in the inner filter container 410 and causing it to adhere to the circumferential θ side wall of the inner filter container 410.

[0131] Subsequently, the motor 310 is stopped, and the pressing block 600 is placed into the inner filter container 410 to compress the extract 002. The motor 310 is then started. During this process, the balancing ring 500 and the counterweight 700 rotate together to improve the dynamic balance of the inner filter container 410 and the outer filter container 420.

[0132] Continue reading Figure 16 After liquid 004 (specifically, water) is added to inner filter container 410, liquid 004 generates centrifugal force as inner filter container 410 rotates, passing through the object to be extracted 002, thereby forming a solution containing the target substance 003 dissolved in the object to be extracted 002. For ease of explanation, this solution will be referred to as liquid 004 below.

[0133] Continue reading Figure 16 As the inner filter container 410 rotates, the liquid 004 in the inner filter container 410 passes through the inner filter container 410 and is thrown out to the outer filter container 420. A portion of the liquid 004 in the outer filter container 420 is thrown out into the liquid storage container 200 through the filter holes on the filter part 423 (as shown in FIG. Figure 16 The other part of the liquid 004 in the outer filter container 420, under the action of centrifugal force, climbs along the circumferential θ side wall of the inclined filter portion 423 to the annular plate (not marked in the figure) on the top side of the filter portion 423, and is squeezed back into the inner filter container 410 as the liquid 004 under the annular plate continues to increase (as shown in the dashed line with the arrow on the bottom side). Figure 16 The process is shown as follows (indicated by the dotted line with an arrow on the top side of the middle part), and then enters the next cycle.

[0134] After the centrifugal extractor 001 of the present invention completes extraction, the liquid 004 in the liquid storage container 200 is discharged through the liquid discharge channel 201 .

[0135] 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 may also configure a plug for the drainage channel 201 as needed to close the drainage channel 201 through the plug, and remove the plug from the drainage channel 201 when drainage is required.

[0136] In the present invention, whether the centrifugal extractor 001 has completed the extraction of the extract 002 can be determined by counting the running time of the motor 310, or by determining whether the solubility of the liquid 004 in the liquid storage container 200 has reached the value set by the user.

[0137] It should be noted that the above-mentioned method of use is only used to help those skilled in the art understand the centrifugal extractor 001 of the present invention, and does not mean that the centrifugal extractor 001 of the present invention only has the above-mentioned method of use.

[0138] Those skilled in the art will appreciate that the connection between the inner filter container 410 and the motor 310 causes static electricity generated by the motor 310 during operation to be transferred to the inner filter container 410. Consequently, before water is added, the extract 002 in the inner filter container 410 is attracted to the inner filter container 410's walls by the static electricity, resulting in uneven distribution of the static electricity. This can cause eccentricity in the inner filter container 410, particularly at the top of the inner filter container 410. The presence of the counterweight 700 increases the moment of inertia of the top of the inner filter container 410, effectively reducing or even preventing eccentric vibrations at the top of the inner filter container 410.

[0139] Based on the foregoing description, those skilled in the art will understand that the centrifugal extractor 001 of the present invention not only improves the completeness of its extraction of the extract 002, but also effectively reduces the noise during the operation of the centrifugal extractor 001 by providing a balance ring 500 and a counterweight block 700, thereby improving the user experience.

[0140] Thus far, the technical solutions of the present invention have been described in conjunction with the above-mentioned multiple embodiments. However, it is easy for those skilled in the art to understand that the scope of protection of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art may split and combine the technical solutions of the above-mentioned various embodiments, and may also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present invention shall fall within the scope of protection of the present invention.
