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 purpose, the present invention provides a centrifugal extractor, comprising:

[0007] liquid storage container;

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

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

[0010] The supporting structure is used to support the filtering device to support the filtering device in a radial direction, thereby improving the dynamic balance of the filtering device and reducing the operating noise of the centrifugal extractor.

[0011] Optionally, the support structure includes a first support structure fixedly connected to or integrally formed with the liquid storage container, and the first support structure is used to support the top of the filter device to prevent eccentric rotation of the top of the filter device.

[0012] Optionally, the filtering device includes an outer filtering container, which includes a filtering portion; the first supporting structure includes a supporting ring extending upward from the inner bottom wall of the liquid storage container, and an inner abutting structure arranged on the inner side of the supporting ring, and the inner abutting structure is in clearance fit or sliding contact with the filtering portion, so that the first supporting structure supports the filtering portion in the radial direction through the inner abutting structure.

[0013] Optionally, the peripheral wall of the filter portion is inclined radially outward from the bottom to the top; the inner abutment structure is arranged to be annular, and / or the inner abutment structure is inclined upward toward the direction close to the filter portion.

[0014] Optionally, the outer filter container further includes a stop portion and an apron portion; the stop portion is located on the top side of the filter portion and is arranged in a ring shape; the apron portion is located on the radially outer side of the stop portion and is arranged in a ring shape, and the apron portion is in a clearance fit or sliding contact with the liquid storage container.

[0015] Optionally, the top end of the first supporting structure is in clearance fit or sliding contact with the stop portion.

[0016] Optionally, the first supporting structure further comprises an external abutting structure provided on the outside of the supporting ring, and the external abutting structure is in clearance fit or sliding contact with the apron portion.

[0017] Optionally, an outer convex ring is provided at the bottom of the apron portion, and the outer filter container is provided with an inner convex ring for clamping the outer convex ring, and the outer convex ring is located at the bottom side of the inner convex ring; the outer abutment structure is located at the top of the apron portion.

[0018] Optionally, the outer filter container further comprises a neck portion located between the filter portion and the stop portion, and a sink is provided between one or both of the filter portion and the neck portion; the centrifugal extractor further comprises a balancing ring embedded in the sink.

[0019] Optionally, the support structure includes a second support structure fixedly connected to the driving device, the second support structure is located on the outside of the filter device and abuts or gap-fits with the bottom of the filter device; and / or, the filter device also includes an inner filter container arranged on the inner side of the outer filter container, and the inner filter container is coaxially fixed with the outer filter container.

[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 the filter device driven by the driving device, the filter device can rotate to centrifugally extract the material to be extracted, and the extracted target substance is ejected from the filter device. During centrifugal extraction, the target substance on the material to be extracted is more easily ejected from the filter device, thereby improving the completeness of the extraction of the material to be extracted.

[0021] Furthermore, the present invention also supports the filter device in the radial direction by providing a support structure for supporting the filter device, thereby improving the dynamic balance of the filter device, reducing the operating noise of the centrifugal extractor, and enhancing the user experience.

[0022] Furthermore, by providing a first supporting structure that is fixedly connected to or integrally formed with the liquid storage container to support the top of the filter device, eccentric rotation of the top of the filter device is effectively prevented.

[0023] Furthermore, by making the support ring of the first support structure extend upward from the inner bottom wall of the liquid storage container and providing an internal abutment structure on the inner side of the support ring, the first support structure can be clearance-fitted or slidingly contacted with the filter part through the internal abutment structure, thereby avoiding the filter part from shaking back and forth during rotation and reducing the operating noise of the centrifugal extractor.

[0024] Furthermore, by tilting the peripheral wall of the filter portion radially outward from the bottom to the top, the inner abutment structure is tilted upward toward the filter portion, so that the inner abutment structure can better support the filter portion when the filter portion shakes.

[0025] Furthermore, by arranging an external abutment structure on the outside of the support ring and making the external abutment structure loosely fit or in sliding contact with the apron portion of the outer filter container, the external abutment structure and the internal abutment structure can simultaneously support the outer filter container outward and inward in the radial direction, which is more conducive to reducing the shaking of the outer filter container during rotation.

[0026] Furthermore, by providing an outer convex ring at the bottom of the apron portion and an inner convex ring on the outer filter container for retaining the outer convex ring, with the outer convex ring positioned on the bottom side of the inner convex ring, the liquid storage container can axially limit the outer filter container, preventing the outer filter container from falling out of the liquid storage container. Furthermore, by positioning the outer abutment structure at the top of the apron portion, while the first support structure supports the outer filter container, the outer convex ring of the outer filter container can also deform appropriately and fit into the bottom side of the inner convex ring.

[0027] 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.

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.

[0057] 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.

[0058] 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, a filtering device 400, a supporting structure 500, an optional balance ring 600 and an optional pressing block 700.

[0059] 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 and the filter device 400, while the bottom cavity 102 is used to accommodate the drive device 300. Of course, as long as the liquid storage container 200, the drive device 300, and the filter device 400 can be installed, those skilled in the art may also configure the housing 100 to any other feasible shape, such as a hollow barrel-shaped member. Alternatively, those skilled in the art may also omit the housing 100 as needed. That is, as long as the liquid storage container 200, the drive device 300, and the filter device 400 can be relatively fixed, those skilled in the art may also omit the housing 100 as needed, or configure the housing 100 and the liquid storage container 200 as a single unit.

[0060] The liquid storage container 200 is used to hold the liquid 004 (such as Figure 16as shown), or the liquid 004 produced during the operation of the centrifugal extractor 001.

[0061] The driving device 300 is relatively fixed to the liquid storage container 200 , and can be specifically fixedly connected to the body 100 .

[0062] The filter device 400 is disposed in the liquid storage container 200 and is connected to the driving device 300 so that the filter device 400 extracts the substance to be extracted 002 (e.g. Figure 16 As 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 filter device 400 into the liquid storage container 200 under the action of centrifugal force.

[0063] The support structure 500 is used to support the filter device 400 so as to Figure 4 As shown in FIG, the filter device 400 is supported on the support frame 401, thereby improving the dynamic balance of the filter device 400 and reducing the operating noise of the centrifugal extractor 001.

[0064] The balance ring 600 is fixed relative to the filter device 400 to improve the dynamic balance of the filter device 400, 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 600 as needed.

[0065] The pressing block 700 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 700 or configure the pressing block 700 as a cover, a stopper, or other component as needed.

[0066] Those skilled in the art will appreciate that, by configuring the filter device 400 to be driven by the drive device 300, the filter device 400 can rotate to centrifugally extract the material to be extracted 002 placed therein, and eject the extracted target substance 003 from the filter device 400. During centrifugal extraction, the target substance 003 on the material to be extracted 002 is more easily ejected from the filter device 400. Therefore, the centrifugal extractor 001 of the present invention improves the completeness of the extraction of the material to be extracted 002.

[0067] Furthermore, the present invention also supports the filter device 400 in the radial direction r by providing a support structure 500 for supporting the filter device 400, thereby improving the dynamic balance of the filter device 400, reducing the operating noise of the centrifugal extractor 001, and enhancing the user experience.

[0068] 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.

[0069] 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.

[0070] 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).

[0071] 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.).

[0072] 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 speed of the filter device 400 through the knob 110 .

[0073] Furthermore, in other embodiments of the present invention, those skilled in the art may, as needed, omit the knob 110 and control the speed of the filter device 400 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 a remote control compatible with the centrifugal extractor 001, or a mobile phone, tablet, or other device connected to the centrifugal extractor 001.

[0074] 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.

[0075] 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 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 body 100. The protruding structure is inserted into the slot, thereby achieving the circumferential θ (as shown in FIG. Figure 4 The 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.

[0076] 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.

[0077] 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 .

[0078] 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 filtering device 400. 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.

[0079] 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 filter device 400, so that the motor 310 drives the filter device 400 to rotate through the connector 320.

[0080] 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 .

[0081] 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.

[0082] 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.

[0083] 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 .

[0084] Furthermore, the connector 320 is fixedly connected to the filter device 400, so that the motor 310 drives the filter device 400 to rotate synchronously through the connector 320. For example, the connector 320 is connected to the filter device 400 by welding or screws.

[0085] In other embodiments of the present invention, those skilled in the art may also configure the connector 320 to be composed of two parts that can rotate synchronously and be detachably connected, as needed, with one part fixedly connected to the rotating shaft of the motor 310 and the other part fixedly connected to the filter device 400. 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.

[0086] In addition, in other embodiments of the present invention, those skilled in the art may also set the driving device 300 to any other feasible form as needed, for example, the driving device 300 only includes the motor 310, and the rotating shaft of the motor 310 is directly fixedly connected to the filtering device 400.

[0087] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the filtration device 400 includes an inner filtration container 410 and an outer filtration container 420 disposed outside the inner filtration container 410 , so as to perform double filtration on the extract 002 through the inner filtration container 410 and the outer filtration container 420 .

[0088] 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.

[0089] 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 700 , thereby preventing the pressing block 700 from falling into the inner filter container 410 .

[0090] like Figure 4 、 Figure 5 、 Figure 8 and Figure 9 As shown, in some embodiments of the present invention, the outer filter container 420 includes a filter portion 421 , so that the outer filter container 420 abuts against the support structure 500 through the filter portion 421 .

[0091] Furthermore, the peripheral wall of the filter portion 421 is inclined outward along the radial direction r from the bottom to the top, so that the liquid 004 moves upward along the peripheral wall of the filter portion 421 under the action of centrifugal force, thereby increasing the filtering area of ​​the filter portion 421.

[0092] like Figure 8 and Figure 9 As shown, in some embodiments of the present invention, the outer filter container 420 may further include a stopper portion 422 and an apron portion 423. The stopper portion 422 is located on the top side of the filter portion 421 and is annular in shape. The apron portion 423 is located radially outward of the stopper portion 422 and is annular in shape. The apron portion 423 is in a clearance fit or in sliding contact with the liquid storage container 200.

[0093] like Figure 4 、 Figures 8 to 11 As shown, in some embodiments of the present invention, an outer convex ring 4231 is provided at the bottom of the apron portion 423 , and the outer filter container 420 is provided with an inner convex ring 220 for clamping the outer convex ring 4231 . The outer convex ring 4231 is located on the bottom side of the inner convex ring 220 .

[0094] It is understood by those skilled in the art that, by providing an outer convex ring 4231 at the bottom of the skirt portion 423, providing an inner convex ring 220 on the outer filter container 420 for clamping the outer convex ring 4231, and making the outer convex ring 4231 located at the bottom side of the inner convex ring 220, the liquid storage container 200 can be tilted in the axial direction z (e.g., Figure 4As shown in FIG. 2 , the outer filter container 420 can be limited to prevent the outer filter container 420 from escaping from the liquid storage container 200 .

[0095] During installation, the outer convex ring 4231 can be deformed by squeezing the skirt portion 423, thereby being installed on the bottom side of the inner convex ring 220. To this end, the outer diameter of the outer convex ring 4231 can be larger than the inner diameter of the inner convex ring 220 by any feasible value such as 0.5mm, 1mm, 1.5mm, or 2mm.

[0096] like Figure 4 、 Figure 5 、 Figures 8 to 11 As shown, in some embodiments of the present invention, the outer filter container 420 may further include a neck portion 424 located between the filter portion 421 and the stop portion 422, and a sink 4201 is provided between one or both of the filter portion 421 and the neck portion 424. The sink 4201 is used to mount the balance ring 600.

[0097] Furthermore, the outer filter container 420 and the balance ring 600 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 600 together by any other feasible method as needed, such as welding, clamping, bonding, etc.

[0098] from Figure 4 and Figure 5 It can be seen that in some embodiments of the present invention, the inner filter container 410 is disposed in the filter portion 421 , and the closing structure 411 of the inner filter container 410 is aligned with the neck 424 of the outer filter container 420 .

[0099] like Figure 8 and Figure 10 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 421 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.

[0100] Of course, those skilled in the art may also provide multiple spoiler ribs 425 on the outside of the filter portion 421 , or provide multiple spoiler ribs 425 on both the inside and outside of the filter portion 421 , as needed.

[0101] Furthermore, in some embodiments of the present invention, the aperture of the filter holes on the inner filter container 410 can be larger than the aperture of the filter holes on the outer filter container 420, so that the flow capacity of the filter part 421 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.

[0102] In addition, in other embodiments of the present invention, those skilled in the art may also omit one of the inner filter container 410 and the outer filter container 420 as needed, for example, omit the inner filter container 410 .

[0103] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the support structure 500 includes a first support structure 510 and an optional second support structure 520 .

[0104] like Figure 1 、 Figure 4 、 Figure 10 and Figure 11 As shown, the first support structure 510 is fixedly connected to or integrally formed with the liquid storage container 200 . The first support structure 510 is used to support the top of the filter device 400 to prevent the top of the filter device 400 from eccentrically rotating.

[0105] like Figure 4 、 Figure 10 and Figure 11 As shown, the first support structure 510 includes a support ring 511 extending upward from the inner bottom wall of the liquid storage container 200, and an inner abutment structure 512 arranged on the inner side of the support ring 511. The inner abutment structure 512 is in clearance fit or sliding contact with the filter part 421, so that the first support structure 510 supports the filter part 421 in the radial direction r through the inner abutment structure 512.

[0106] from Figure 4 、 Figure 10 and Figure 11 As can be seen in the figure, the inner abutment structure 512 is configured as a ring to improve the structural strength of the inner abutment structure 512. Furthermore, the inner abutment structure 512 can be tilted upward toward the direction close to the filter portion 421 so that the inner abutment structure 512 can better support the filter portion 421 when the filter portion 421 shakes.

[0107] from Figure 4 As can be seen, in some embodiments of the present invention, the top end of the first support structure 510 is in clearance fit or sliding contact with the stopper 422 , so that the first support structure 510 can support the outer filter container 420 in the axial direction z.

[0108] like Figure 4 、 Figure 10 and Figure 11 As shown, in some embodiments of the present invention, the first support structure 510 further includes an outer abutting structure 513 disposed outside the support ring 511 , and the outer abutting structure 513 is in clearance fit or sliding contact with the apron portion 423 .

[0109] Those skilled in the art will appreciate that the first support structure 510 can provide a radially inward force r to the outer filter container 420 through the inner abutment structure 512, provide a radially outward force r to the outer filter container 420 through the outer abutment structure 513, and provide an axial support force z to the outer filter container 420 through the top of the support ring 511, thereby providing support in multiple dimensions for the outer filter container 420 and effectively avoiding shaking during rotation.

[0110] In particular, the radially inward force r exerted by the inner abutment structure 512 on the outer filter container 420 effectively prevents the outer filter container 420 from being impacted by the centrifugal force of the solution therein and thereby offsets the impact force generated by the solution. Furthermore, the radially outward force r exerted by the outer abutment structure 513 on the outer filter container 420 effectively prevents the outer filter container 420 from being deformed by the compressive force of the liquid storage container 200 during rotation due to eccentricity.

[0111] from Figure 4 、 Figure 10 and Figure 11 As can be seen in the figure, the outer abutment structure 513 is located at the top of the apron portion 423 to ensure that the outer convex ring 4231 of the outer filter container 420 is embedded in the bottom side of the inner convex ring 220 of the liquid storage container 200 while the first support structure 510 can support the outer filter container 420.

[0112] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the second support structure 520 is located outside the filter device 400 and abuts against or has a clearance fit with the bottom of the filter device 400 .

[0113] Furthermore, the second support structure 520 can be fixedly connected to or integrally formed with the connector 320, for example, by being welded together. Those skilled in the art will appreciate that the second support structure 520 can position the outer filter container 420 on the connector 320, thereby ensuring the coaxiality between the outer filter container 420 and the connector 320.

[0114] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the second support structure 520 may be annular to increase the contact area between the second support structure 520 and the outer filter container 420 .

[0115] like Figure 12 and Figure 13 As shown, in some embodiments of the present invention, the balancing ring 600 defines an annular cavity 601, and the annular cavity 601 is filled with a balancing liquid 650. In this way, the material of the balancing ring 600 is saved and the overall weight of the balancing ring 600 is ensured.

[0116] In the present invention, the balancing liquid 650 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 650, thereby enabling the balancing liquid 650 to operate at a lower ambient temperature and preventing the balancing liquid 650 from bursting the balancing ring 600 due to operation at a lower ambient temperature.

[0117] like Figure 13 As shown, in some embodiments of the present invention, the balance ring 600 is provided with an annular rib 630 in the annular cavity 601 to separate the annular cavity 601 into an inner annular cavity 6011 and an outer annular cavity 6012 .

[0118] It will be understood by those skilled in the art that the inner annular cavity 6011 and the outer annular cavity 6012 enable the balancing liquid 650 to be evenly distributed in the inner annular cavity 6011 and the outer annular cavity 6012, thereby preventing the balancing liquid 650 from being affected by centrifugal force and concentrated on the outer side of the annular cavity 601 when the balance ring 600 rotates rapidly, thereby preventing the outer wall of the annular cavity 601 from being easily leaked due to excessive pressure.

[0119] from Figure 13 As can be seen in the figure, there is a gap between the inner annular cavity 6011 and the outer annular cavity 6012, so that the balancing liquid 650 can flow in the inner annular cavity 6011 and the outer annular cavity 6012, thereby being evenly distributed in the inner annular cavity 6011 and the outer annular cavity 6012.

[0120] like Figure 13 As shown, in some embodiments of the present invention, the balancing ring 600 is provided with at least one water-repelling rib 640 in the inner ring cavity 6011 and / or the outer ring cavity 6012 , so that the balancing ring 600 drives the balancing liquid 650 to rotate through the water-repelling rib 640 .

[0121] It can be understood by those skilled in the art that, under the action of the water-repellent rib 640 , the balancing liquid 650 first partially rotates and then gradually rotates completely, thereby reducing the load on the filter device 400 and the balance ring 600 when they first start to rotate, thereby reducing the starting power of the drive device 300 .

[0122] like Figures 12 to 15 As shown, in some embodiments of the present invention, the balance ring 600 includes an upper annular shell 610 with an opening facing downward and a lower annular shell 620 with an opening facing upward. The upper annular shell 610 and the lower annular shell 620 are sealed and connected to define an annular cavity 601.

[0123] The upper annular shell 610 and the lower annular shell 620 may be sealed and connected together by any feasible means such as welding, threaded connection, etc.

[0124] 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 610 and the lower annular shell 620 to allow the balancing liquid 650 to be filled into the annular cavity 601 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.

[0125] In addition, under the premise of being able to be filled with the balancing liquid 650 , those skilled in the art may also configure the balancing ring 600 to any other feasible form, such as an integrally made rubber ring, as needed.

[0126] like Figures 13 to 15 As shown, in some embodiments of the present invention, the annular rib 630 includes an upper annular rib 631 disposed within the upper annular shell 610 and a lower annular rib 632 disposed within the lower annular shell 620. Furthermore, a gap is provided between the ends of the upper annular rib 631 and the lower annular rib 632 that are close to each other to ensure that the inner annular cavity 6011 and the outer annular cavity 6012 are connected.

[0127] It will be understood by those skilled in the art that when the upper annular shell 610 and the lower annular shell 620 are squeezed relatively close to each other, the upper annular rib 631 and the lower annular rib 632 can also abut against each other to prevent excessive deformation of the upper annular shell 610 and the lower annular shell 620, thereby improving the structural strength of the balance ring 600.

[0128] like Figures 13 to 15 As shown, in some embodiments of the present invention, the water-repellent rib 640 is disposed in the lower annular shell 620 so that the balancing liquid 650 rotates sequentially from bottom to top when the balancing ring 600 rotates.

[0129] like Figure 13 and Figure 15 As shown, in some embodiments of the present invention, in the radial direction r of the lower annular shell 620 , the height of the water-repellent rib 640 may gradually decrease toward the direction approaching the lower annular rib 632 .

[0130] Those skilled in the art will appreciate that the provision of the water-repellent rib 640 enhances the structural strength of the lower annular shell 620 , and in particular, in conjunction with the lower annular rib 632 , can effectively prevent the lower annular shell 620 from deformation.

[0131] Return to view Figures 1 to 5 As shown, in some embodiments of the present invention, the pressing block 700 is configured in a ring shape so that the object to be extracted 002 can be put into the inner filtration container 410 through the hollow area of ​​the pressing block 700 .

[0132] from Figures 1 to 5As can be seen in the figure, in some embodiments of the present invention, the thickness of the pressing block 700 gradually decreases from the outside to the inside, and the two opposing annular surfaces of the pressing block 700 are both configured as funnel surfaces, so that the extract 002 placed on the top surface of the pressing block 700 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 700 as funnel surfaces, the user does not need to distinguish the front and back of the pressing block 700 when installing it, which is convenient for the user.

[0133] 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.

[0134] like Figure 16 As shown, after the material to be extracted 002 is placed in the inner filter container 410, the pressing block 700 is placed inside the inner filter container 410, and the motor 310 is started. The motor 310 drives the filter device 400 in a forward rotation, thereby generating centrifugal force on the material to be extracted 002 in the inner filter container 410 and causing it to adhere to the circumferential sidewalls of the inner filter container 410. During this process, the balance ring 600 rotates along with the outer filter container 420 to improve the dynamic balance of the filter device 400.

[0135] 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.

[0136] 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 421 (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 side wall of the inclined filter portion 421 to the annular plate (not marked in the figure) on the top side of the filter portion 421, 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.

[0137] 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 .

[0138] 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.

[0139] 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.

[0140] 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 can only have the above-mentioned method of use.

[0141] Based on the foregoing description, those skilled in the art will appreciate that the centrifugal extractor 001 of the present invention not only improves the completeness of its extraction of the extract 002 , but also reduces operating noise by providing a support structure 500 , thereby improving the user experience.

[0142] 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.
