Description

Technical Field

[0001] The utility model belongs to the technical field of beverage extraction equipment, and specifically provides a centrifugal extractor that is easy to clean. 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.

[0004] Moreover, after the extraction is completed, the extract is likely to adhere to the peripheral wall of the extraction device and is difficult to remove, which increases the user's workload and poor user experience. Utility Model Content

[0005] One purpose of the present invention is to solve the problem in existing extraction equipment that after extraction, the extract is easily adhered to the peripheral wall and is difficult to remove.

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

[0010] The scraper is detachably mounted on the inner bottom of the first filter container to remove the extracted material from the first filter container.

[0011] Optionally, the scraper is provided with an upwardly protruding handle for a user to hold and remove the scraper from the first filter container.

[0012] Optionally, a clamping structure is provided on the handle, so that the scraper is fixed relative to the first filter container through the clamping structure.

[0013] Optionally, the centrifugal extractor further comprises a fixing member fixed relative to the first filter container, and the fixing member is provided with a snap-fitting structure so that the scraper is snap-fitted to the snap-fitting structure through the snap-fitting structure.

[0014] Optionally, the centrifugal extractor further comprises a second filter container arranged outside the first filter container, and the second filter container is coaxially fixed to the first filter container; the fixing member is fixedly connected to the second filter container or is made integrally therewith.

[0015] Optionally, the handle defines a accommodating cavity with an opening facing downward; the snap-fit ​​structure is a slot provided on a side wall of the accommodating cavity; and the snap-fitting structure is a buckle provided on the fixing member.

[0016] Optionally, the fixing member includes an outer tube column provided with the buckle, an inner tube column provided inside the outer tube column, and a bottom plate connecting the outer tube column and the inner tube column together, and a connecting hole is provided on the bottom plate to fix it together with the bottom wall of the second filter container through the connecting hole.

[0017] Optionally, a mounting hole aligned with the connecting hole is provided on the bottom wall of the second filter container, so that screws, bolts or rivets pass through the connecting hole and the mounting hole to fix the bottom plate and the second filter container together.

[0018] Optionally, the centrifugal extractor further comprises a spring embedded in the inner tube column, wherein the spring is configured to abut against the handle to provide a force for the scraper to move away from the second filter container.

[0019] Optionally, the bottom wall of the first filter container is configured as a hollow annular structure to avoid the fixing component and enable the first filter container to carry the scraper in the axial direction through the annular structure.

[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 a first filter container driven by a driving device, the first filter container can be rotated to centrifugally extract the material to be extracted therein, and the extracted target substance is ejected from the first filter container. During centrifugal extraction, the target substance in the material to be extracted is more easily ejected from the first filter container, thereby improving the completeness of the extraction of the material to be extracted by the centrifugal extractor of the present invention.

[0021] In addition, the present invention also provides a scraper that is detachably mounted on the bottom of the first filter container to remove the extracted material from the first filter container, which makes it convenient for users to remove the extracted material from the first filter container and improves the user experience.

[0022] Furthermore, a handle is provided on the scraper for the user to hold, thereby facilitating the user to take the scraper out of the first filter container.

[0023] Furthermore, by providing a snap-fit ​​structure on the handle, the scraper can be fixed relative to the first filter container through the snap-fit ​​structure, so that the scraper can rotate together with the first filter container, thereby preventing the scraper from moving the material to be extracted in the first filter container when the first filter container rotates.

[0024] Furthermore, by connecting the scraper to the fixing member via a slot and a buckle, the scraper is easily fixed and removed. By providing a spring on the fixing member, the scraper can be automatically ejected by the spring when the slot and buckle are disengaged, improving the user experience when removing the scraper.

[0025] 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.

[0055] 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.

[0056] like Figures 1 to 5As 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 first filter container 400, an optional second filter container 500, a scraper 600, an optional fixing member 700, an optional spring 800 and an optional annular pressure block 900.

[0057] 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 first filter container 400, and the second filter container 500, while the bottom cavity 102 is used to accommodate the drive device 300. Of course, those skilled in the art may also design the housing 100 into any other feasible shape, such as a hollow barrel-shaped member, as needed, provided that the liquid storage container 200, the drive device 300, the first filter container 400, and the second filter container 500 can be accommodated. Alternatively, those skilled in the art may also omit the housing 100 as needed. That is, those skilled in the art may also omit the housing 100 as needed, or integrate the housing 100 with the liquid storage container 200, as needed, provided that the liquid storage container 200, the drive device 300, the first filter container 400, and the second filter container 500 can be relatively fixed.

[0058] The liquid storage container 200 is used to hold the liquid 004 (such as Figure 14 as shown), or the liquid 004 produced during the operation of the centrifugal extractor 001.

[0059] The driving device 300 is relatively fixed to the liquid storage container 200 , and can be specifically fixedly connected to the body 100 .

[0060] The first filter container 400 is disposed in the liquid storage container 200 and is connected to the driving device 300. The first filter container 400 is used to rotate the liquid to be extracted 002 (such as Figure 14 As shown) for centrifugal extraction, and the extracted target substance 003 (as shown Figure 14 As shown), the first filter container 400 is thrown out.

[0061] The second filter container 500 is disposed between the liquid storage container 200 and the first filter container 400 and is connected to the driving device 300 to re-filter the extracted target substance 003. In addition, those skilled in the art may also omit the second filter container 500 as needed.

[0062] The scraper 600 is detachably mounted to the inner bottom of the first filter container 400 to remove the extracted object 002 from the first filter container 400 .

[0063] The fixing member 700 is fixedly connected to the second filter container 500 and is used to mount the scraper 600. Alternatively, those skilled in the art may fix the fixing member 700 to the first filter container 400, or omit the fixing member 700 and directly mount the scraper 600 to the first filter container 400 or the second filter container 500, as needed.

[0064] The spring 800 is used to provide elastic force to the scraper 600 to facilitate the user to disassemble the scraper 600.

[0065] The annular pressing block 900 is removably mounted in the first filter container 400 to compress the material to be extracted 002 in the first filter container 400 and prevent it from being thrown out of the first filter container 400. The hole in the center of the annular pressing block 900 facilitates the user to add the material to be extracted 002 and water to the first filter container 400. Of course, those skilled in the art may also configure the annular pressing block 900 as a solid plate-like structure or omit the annular pressing block 900 as needed.

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

[0067] In addition, the present invention also provides a scraper 600 that is detachably mounted on the bottom of the first filter container 400 to remove the extracted object 002 from the first filter container 400, which makes it convenient for users to remove the extracted object 002 from the first filter container 400 and improves 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 generates liquid 004 in which the target substance 003 is dissolved during the process of extracting the object 002 to be extracted.

[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 speeds of the first filter container 400 and the second filter container 500 .

[0073] 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 first and second filter containers 400 and 500 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.

[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 2 As shown, a protrusion (not labeled) is provided on the peripheral wall of the liquid storage container 200. The housing 100 is provided with a slot (not labeled) that matches the protrusion. The protrusion is inserted into the slot, thereby achieving circumferential θ-fixation of the liquid storage container 200 and the housing 100. A lug (not labeled) may also be provided on the side of the liquid storage container 200 away from the protrusion. The housing 100 is provided with a corresponding slot (not labeled), and the lug is inserted into the slot to further achieve circumferential θ-fixation of the liquid storage container 200 and the housing 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 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 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 and Figure 4 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 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.

[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 coaxially 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 welded or screwed to the second filter container 500, and the first filter container 400 is welded or screwed to the second filter container 500.

[0085] In other embodiments of the present invention, those skilled in the art may also configure the connector 320 as needed to be divided into 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 first filter container 400 and the second filter container 500. 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] Furthermore, in other embodiments of the present invention, those skilled in the art may configure the drive device 300 in any other feasible form as needed, for example, the drive device 300 may include only the motor 310, and the rotating shaft of the motor 310 may be directly fixedly connected 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 fixedly connected to only one of the first filter container 400 and the second filter container 500, the first filter container may be connected to the other of the first filter container 400 and the second filter container 500 by welding, riveting, clamping, bolting, or the like.

[0087] like Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, in some embodiments of the present invention, the first filter container 400 is generally barrel-shaped. A plurality of first filter holes (not labeled in the figure) are provided on the first circumferential sidewall 410 of the first filter container 400. The plurality of first filter holes are evenly distributed on the first circumferential sidewall 410 of the first filter container 400.

[0088] Furthermore, the bottom wall of the first filter container 400 is configured as a hollow annular structure 420 to avoid the fixing member 700 and enable the first filter container 400 to support the scraper 600 in the axial direction z via the annular structure 420 .

[0089] Furthermore, the scraper 600 and the first circumferential side wall 410 of the first filter container 400 are clearance-matched in the radial direction r to ensure that when the scraper 600 can be installed in the first filter container 400 and removed from the first filter container 400, the gap between the scraper 600 and the first circumferential side wall 410 of the first filter container 400 is as small as possible, thereby improving the scraping effect of the scraper 600 on the extract 002 on the first circumferential side wall 410.

[0090] like Figure 1 、 Figure 2 、 Figure 4 and Figure 7 As shown, in some embodiments of the present invention, a plurality of second filter holes (not marked in the figure) are provided on the second circumferential side wall 510 of the second filter container 500, and the second circumferential side wall 510 of the second filter container 500 is inclined outward from the bottom to the top so that the liquid 004 rises to the top of the second circumferential side wall 510 under the action of centrifugal force.

[0091] like Figure 7 As shown, in some embodiments of the present invention, the second filter container 500 further includes an annular plate 520 , which extends from the top of the second circumferential side wall 510 toward the first filter container 400 and abuts against the first filter container 400 to prevent the solution from being thrown out of the second filter container 500 .

[0092] like Figure 7 As shown, in some embodiments of the present invention, the second filter container 500 further includes an inner ring portion 530, a top plate 540, and an outer ring portion 550. The bottom end of the inner ring portion 530 is connected to the annular plate 520, the top end of the inner ring portion 530 is connected to the inner edge of the top plate 540, and the outer edge of the top plate 540 is connected to the top end of the outer ring portion 550.

[0093] like Figure 4 As shown, in the assembled state, the inner ring portion 530 abuts against the first circumferential side wall 410 of the first filter container 400 to increase the connection area between the second filter container 500 and the first filter container 400, thereby improving the stability of the second filter container 500 and the first filter container 400 during rotation.

[0094] Furthermore, the inner annular portion 530 and the first circumferential sidewall 410 of the first filter container 400 may be interference-fitted.

[0095] like Figure 4 As shown, in the assembled state, the top plate 540 can abut against the top annular edge of the first filter container 400 to prevent other substances such as the extract 002 from entering the second filter container 500 through the gap between the first filter container 400 and the second filter container 500.

[0096] like Figure 4 As shown, in the assembled state, the outer ring portion 550 abuts against the liquid storage container 200 to prevent foreign matter from entering the liquid storage container 200 and affecting the taste of the final solution.

[0097] like Figure 7 As shown, in some embodiments of the present invention, a mounting hole 501 is provided on the bottom wall of the second filter container 500, so that the fixing member 700 can be fixed thereto. Specifically, an upwardly protruding boss (not marked in the figure) is formed on the bottom wall of the second filter container 500, and the mounting hole 501 is formed on the boss by stamping.

[0098] like Figure 8 and Figure 9 As shown, in some embodiments of the present invention, the scraper 600 is provided with an upwardly protruding handle 610 for the user to hold and remove the scraper 600 from the first filter container 400 .

[0099] Furthermore, a snap-fit ​​structure 611 is provided on the handle 610 , so that the scraper 600 is fixed relative to the first filter container 400 via the snap-fit ​​structure 611 .

[0100] like Figure 10 and Figure 11 As shown, in some embodiments of the present invention, the centrifugal extractor 001 also includes a fixing member 700 fixed relative to the first filter container 400, and a snap-fitting structure 710 is provided on the fixing member 700 so that the scraper 600 is snap-fitted to the snap-fitting structure 710 through the snap-fitting structure 611.

[0101] from Figures 8 to 11 As can be seen in the figure, the handle 610 defines a accommodating cavity 6101 with an opening facing downward, the snap-fit ​​structure 611 is a snap-fit ​​groove 6111 provided on the side wall of the accommodating cavity 6101 , and the snap-fitting structure 710 is a snap-fit ​​711 provided on the fixing member 700 .

[0102] like Figure 4 and Figure 5 As shown, when the scraper 600 is installed in the first filter container 400 , the fixing member 700 extends into the accommodating cavity 6101 , and the buckle 711 is embedded in the slot 6111 , thereby fixing the scraper 600 and the fixing member 700 together.

[0103] like Figure 12 and Figure 13As shown, when the scraper 600 is removed from the first filter container 400, the user first presses the buckle 711 manually or with a tool such as pliers or a screwdriver to push the buckle 711 inward out of the slot 6111. At this point, the scraper 600 automatically springs upward a certain distance under the action of the spring 800, thereby separating the buckle 711 from the slot 6111. The user can then remove the scraper 600, thereby removing the material to be extracted 002 from the first filter container 400.

[0104] When the scraper 600 needs to be installed into the first filter container 400 again, the user only needs to insert the fixing member 700 into the receiving cavity 6101 of the handle 610 , align the buckle 711 with the slot 6111 , and press downward.

[0105] In addition, in other embodiments of the present invention, those skilled in the art may also configure the snap-fit ​​structure 611 and the snap-fit ​​structure 710 as any other feasible structures as needed. For example, the snap-fit ​​structure 611 may be configured as a buckle 711 and the snap-fit ​​structure 710 may be configured as a slot 6111.

[0106] like Figure 10 and Figure 11 As shown, in some embodiments of the present invention, the fixing member 700 includes an outer tube column 720 provided with the aforementioned buckle 711, an inner tube column 730 provided inside the outer tube column 720, and a bottom plate 740 connecting the outer tube column 720 and the inner tube column 730. The bottom plate 740 is provided with a connecting hole 741 so as to be fixed to the bottom wall of the second filter container 500 through the connecting hole 741.

[0107] Furthermore, the connection hole 741 is aligned with the mounting hole 501 on the second filter container 500 , so that screws, bolts or rivets pass through the connection hole 741 and the mounting hole 501 to fix the bottom plate 740 and the second filter container 500 together.

[0108] Alternatively, those skilled in the art may also fix the fixing member 700 and the second filter container 500 together by welding, clamping or any other feasible connection method as needed; or, configure the fixing member 700 and the second filter container 500 as a whole.

[0109] like Figure 4 、 Figure 5 、 Figure 10 and Figure 11 As shown, the spring 800 is embedded in the inner column 730 and is capable of abutting the handle 610 to provide a force for the scraper 600 to move away from the second filter container 500 .

[0110] Those skilled in the art will appreciate that by providing a spring 800 on the fixing member 700 , the scraper 600 can be automatically popped out a certain distance by the spring 800 when the slot 6111 is disengaged from the buckle 711 , thereby improving the user experience when removing the scraper 600 .

[0111] Alternatively, those skilled in the art may also omit the provision of the spring 800 as needed. However, in this case, the user is required to pull up the scraper 600 when pressing the buckle 711 to separate the buckle 711 from the slot 6111 to prevent the buckle 711 from being reconnected after being separated from the slot 6111.

[0112] In addition, in other embodiments of the present invention, those skilled in the art may also, as needed, fix the fixing member 700 and the first filter container 400 to be connected or integrally formed.

[0113] When the fixing member 700 is fixedly connected to the first filter container 400, the bottom wall of the first filter container 400 can be set as a circular plate without a hollow structure, and then the fixing member 700 and the first filter container 400 are fixedly connected together by bolts, screws, rivets and other components, or the fixing member 700 and the first filter container 400 are fixedly connected together by welding, clamping and other methods.

[0114] Furthermore, in other embodiments of the present invention, those skilled in the art may also, as needed, detachably connect the scraper 600 directly to the first filter container 400 or the second filter container 500. For example, a plurality of magnets may be provided on the scraper 600 to detachably connect the scraper 600 directly to the first filter container 400 or the second filter container 500 through magnetic attraction.

[0115] Furthermore, although not shown in the figures, in some embodiments of the present invention, the centrifugal extractor 001 may also include or be configured with a circulation system. This circulation system comprises an inlet pipe, a pump, and an outlet pipe, which are fluidically connected in sequence. The end of the inlet pipe, remote from the pump, is located within the liquid storage container 200, while the end of the outlet pipe, remote from the pump, is located on the top side of the first filter container 400. This allows the pump to pump liquid from the liquid storage container 200 into the first filter container 400 when the pump is in operation.

[0116] Refer to the following Figure 14 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 14 The filtering holes on the first filtering container 400 are hidden in the figure to facilitate intuitive observation by those skilled in the art.

[0117] like Figure 14As shown, the scraper 600 is first installed in the first filter container 400. Then, the material to be extracted 002 is placed in the first filter container 400, and the pressing block 900 is placed in the first filter container 400. Then, the motor 310 is started. The motor 310 drives the first filter container 400 and the second filter container 500 to rotate in the forward direction, thereby generating centrifugal force on the material to be extracted 002 in the first filter container 400 and causing it to adhere to the circumferential side wall of the first filter container 400.

[0118] Continue reading Figure 14 After liquid 004 (specifically, water) is added to first filter container 400, liquid 004 generates centrifugal force as first filter container 400 rotates, passing through the material to be extracted 002, thereby forming a solution containing the target substance 003 dissolved in the material to be extracted 002. For ease of explanation, this solution will be referred to as liquid 004 below.

[0119] Continue reading Figure 14 As the first filter container 400 rotates, the liquid 004 in the first filter container 400 passes through the first filter container 400 and is thrown into the second filter container 500. The liquid 004 in the second filter container 500 is thrown into the liquid storage container 200 through the filter holes on the filter part.

[0120] During this process, the pump is controlled to operate so as to pump the liquid 004 in the liquid storage container 200 into the first filter container 400 , thereby performing cyclic extraction on the object to be extracted 002 .

[0121] Alternatively, water may be slowly added to the first filter container 400 while the motor 310 is running, so that the first filter container 400 slowly and continuously throws out the water therein.

[0122] from Figures 1 to 4 As can be seen from the figure, in the present invention, the pressing block 900 can be configured in a ring shape to facilitate adding water into the first filter container 400 .

[0123] 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 .

[0124] When the object to be extracted 002 needs to be removed, the user presses the buckle 711 manually or with a tool such as pliers or a screwdriver to push the buckle 711 inward out of the slot 6111. At this point, the scraper 600 automatically springs upward a certain distance under the action of the spring 800, and the user can then remove the scraper 600, thereby removing the object to be extracted 002 from the first filter container 400.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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 the extraction of the extract 002 , but also facilitates the user in removing the extract 002 after extraction from the first filter container 400 , thereby improving the user experience.

[0129] 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.
