Description

Technical Field

[0001] The utility model belongs to the technical field of beverage extraction equipment, and specifically provides a centrifugal extractor with a self-cleaning function. 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, the material to be extracted easily adheres to the peripheral wall of the extraction device, making it difficult to clean, thereby increasing the difficulty of cleaning the extraction device. Utility Model Content

[0005] One purpose of the present invention is to solve the problem that the existing extraction equipment has poor extraction integrity and is difficult to clean.

[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] The first filter container is arranged in the liquid storage container and is drivingly connected to the driving device. The inner circumferential surface of the first filter container is provided with a first rib, which extends along the circumference of the first filter container and bends back and forth along the axial direction of the first filter container.

[0010] Optionally, the first ribs are connected end to end in a circumferential direction of the first filter container to form a ring; and / or, a portion of the first rib is penetrated by the first filter hole on the first filter container.

[0011] Optionally, the first ribs are distributed in the shape of a sine function in the circumferential direction of the first filter container.

[0012] Optionally, a distance between upper and lower edges of the first rib in the axial direction of the first filter container is selected from any value between 3 mm and 10 mm.

[0013] Optionally, the spacing between the upper and lower edges of the first rib in the axial direction of the first filter container is selected from any value between 5 mm and 8 mm; and / or the thickness of the first rib extending inward from the first filter container is selected from any value between 4 mm and 8 mm.

[0014] Optionally, the cross section of the first rib is trapezoidal or conical.

[0015] Optionally, the first rib is provided at the bottom of the first filter container; and / or, the centrifugal extractor further comprises a pressing block detachably mounted to the inner side of the top of the first filter container, the pressing block abutting against the first rib.

[0016] Optionally, the centrifugal extractor further comprises a second filter container arranged between the liquid storage container and the first filter container; the second filter container is drive-connected to the drive device; and a filter cavity for filtering liquid is formed between the second filter container and the bottom of the first filter container; the second filter container is provided with a second filter hole on the portion of the outer side wall of the filter cavity.

[0017] Optionally, a second rib is provided on the inner side of the portion of the second filter container constituting the outer side wall of the filter cavity to disturb the liquid in the filter cavity.

[0018] Optionally, the portion of the second filter container constituting the outer side wall of the filter cavity is configured to be conical to increase the filtering area of ​​the outer side wall of the filter cavity; and / or, the second rib is configured to be strip-shaped.

[0019] 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 rotate to centrifugally extract the material to be extracted, 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. Furthermore, the present invention further disturbs or fixes the material within the first filter container by providing a first rib on the inner circumferential surface of the first filter container, extending along the circumference of the first filter container and bending back and forth along the axial direction of the first filter container. In particular, when cleaning the first filter container, the water within the first filter container is disturbed by the first rib, forming a turbulent flow, which increases the impact of the water flow on the first filter container, thereby improving the cleaning effect of the first filter container and reducing the difficulty of cleaning the extraction equipment. Therefore, the centrifugal extractor of the present invention has a self-cleaning function.

[0020] Furthermore, by extending the first rib along the circumference of the first filter container and bending back and forth along the axial direction of the first filter container, the first rib can form forward and backward action and reaction forces on the substance in the first filter container, thereby improving the stirring effect of the first rib on the substance in the first filter container.

[0021] Furthermore, while the first rib extends along the circumference of the first filter container and bends back and forth along the axial direction of the first filter container, the first rib is connected end to end in a ring shape in the circumferential direction of the first filter container, so that the center of gravity of the entire first filter container can basically coincide with the rotation axis of the first filter container, thereby ensuring the stability of the first filter container during rotation.

[0022] Furthermore, by partially penetrating the first rib through the first filter hole on the first filter container, the filtering effect of the first filter container is ensured.

[0023] Furthermore, by distributing the first ribs in the shape of a sine function in the circumferential direction of the first filter container, the first ribs can not only cause turbulence of the water or other liquid in the first filter container, but also prevent the first ribs from impacting the water or other liquid due to the presence of sharp bends and generating loud noise.

[0024] Furthermore, by selecting the spacing between the upper and lower edges of the first rib in the axial direction of the first filter container from any value between 3 mm and 10 mm, especially from any value between 5 mm and 8 mm, the first rib can cause the water or other liquid in the first filter container to form turbulence while reducing the impact angle between the first rib and the water or other liquid, thereby reducing the noise during the operation of the centrifugal extractor.

[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.

[0049] 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. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0050] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element described must have a specific orientation, be constructed, or operate in a specific orientation. 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.

[0051] 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.

[0052] 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 first filter container 400, an optional second filter container 500 and an optional pressing block 600.

[0053] 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, as long as the liquid storage container 200, the drive device 300, the first filter container 400, and the second filter container 500 can be accommodated, 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. 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, the first filter container 400, and the second filter container 500 can be relatively fixed, those skilled in the art may also omit the housing 100 as needed, or integrate the housing 100 and the liquid storage container 200.

[0054] The liquid storage container 200 is used to hold the liquid 004 (such as Figure 12 as shown), or the liquid 004 produced during the operation of the centrifugal extractor 001.

[0055] The driving device 300 is relatively fixed to the liquid storage container 200 , and can be specifically fixedly connected to the body 100 .

[0056] The inner circumference of the first filter container 400 is provided with a first rib 401, and the first rib 401 is provided along the circumferential direction θ (such as Figure 4 ) and extends along the axial direction z of the first filter container 400 (as shown Figure 4 As shown) bends back and forth so that the first rib 401 breaks up or disperses the agglomerated material in the first filter container 400 as the first filter container 400 rotates. The substance can be a solid substance (such as the extract 002 described later), a liquid substance (such as the liquid 004 described later), or a solid-liquid mixture. The circumferential θ side wall of the first filter container 400 provided with the first rib 401 is recorded as the first circumferential side wall 410 and is provided with a plurality of first filter holes 411. 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 extract 002 (such as Figure 12As shown) for centrifugal extraction, and the extracted target substance 003 (as shown Figure 12 The small triangle shown in the figure) passes through the first filtering hole 411.

[0057] In the present invention, a portion of the first rib 401 can be penetrated by the first filter hole 411 on the first filter container 400. Specifically, the portion of the first rib 401 that aligns with the first filter hole 411 can be penetrated by the first filter hole 411. Alternatively, those skilled in the art can prevent this portion from being penetrated by the first filter hole 411 as needed.

[0058] The circumferential sidewall of the second filter container 500, designated as the second circumferential sidewall 510, is provided with a plurality of second filter holes 511. The second filter container 500 is disposed between the liquid storage container 200 and the first filter container 400 and is drivably connected to the drive device 300. The apertures of the second filter holes 511 are smaller than the apertures of the first filter holes 411, so that the extracted target substance 003 is filtered through the second filter holes 511. Furthermore, those skilled in the art may omit the second filter container 500 as needed.

[0059] The pressing block 600 is detachably mounted in the first filter container 400 to compress the material to be extracted 002 in the first filter container 400 and prevent the material to be extracted 002 from being thrown out of the first filter container 400. In addition, those skilled in the art may also omit the pressing block 600 as needed.

[0060] Those skilled in the art will appreciate that the present invention, by configuring a first filter container 400 driven by a drive device 300, enables the first filter container 400 to perform centrifugal extraction on the material to be extracted 002 contained therein through rotation, and ejects 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. Furthermore, the present invention further disrupts or stabilizes the material within the first filter container 400 by providing a first rib 401 on the inner circumferential surface of the first filter container 400, with the first rib 401 extending along the circumferential direction θ of the first filter container 400 and bending back and forth along the axial direction z of the first filter container 400. Especially when cleaning the first filter container 400, the water inside the first filter container 400 can be disturbed by the first rib 401, forming a turbulent flow. This increases the impact of the water flow on the first filter container 400, thereby improving the cleaning effect of the first filter container 400 and reducing the cleaning difficulty of the extraction device. It can be seen that the centrifugal extractor 001 of the present invention has a self-cleaning function.

[0061] Furthermore, by extending the first rib 401 along the circumferential direction θ of the first filter container 400 and bending back and forth along the axial direction z of the first filter container 400, the first rib 401 can form forward and backward action and reaction forces on the substance in the first filter container 400, thereby improving the stirring effect of the first rib 401 on the substance in the first filter container 400.

[0062] 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.

[0063] 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.

[0064] The centrifugal extractor 001 of the present invention produces a solution of the target substance 003 (such as Figure 12 Liquid 004 (shown in the small triangle).

[0065] 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.).

[0066] 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 .

[0067] 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.

[0068] like Figures 1 to 4As 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.

[0069] 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 5 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.

[0070] 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.

[0071] 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 .

[0072] 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.

[0073] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5As 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.

[0074] 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 .

[0075] 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.

[0076] 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.

[0077] 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 .

[0078] Furthermore, the connector 320 is fixedly connected to the first filter container 400 and the second filter container 500, so that the motor 310 drives the first filter container 400 and the second filter container 500 to rotate synchronously through the connector 320. For example, the connector 320 is 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.

[0079] In other embodiments of the present invention, those skilled in the art may also, as needed, provide the connector 320 with 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 protruding teeth 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.

[0080] 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.

[0081] like Figures 4 to 7 As shown, in some embodiments of the present invention, the first rib 401 is connected end to end in a ring shape in the circumferential direction θ of the first filter container 400, so that when the first rib 401 extends along the circumferential direction θ of the first filter container 400 and bends back and forth along the axial direction z of the first filter container 400, the center of gravity of the entire first filter container 400 can basically coincide with the rotation axis of the first filter container 400, thereby ensuring the stability of the first filter container 400 during rotation.

[0082] like Figures 5 to 7 As shown, in some embodiments of the present invention, the number of first ribs 401 can be one, two, three, or more. When there are two or more first ribs 401, two adjacent first ribs 401 are spaced apart. The specific spacing can be any feasible value, such as 1 mm, 2 mm, 5 mm, 10 mm, or 20 mm.

[0083] Continue reading Figures 5 to 7 In some embodiments of the present invention, the first rib 401 is distributed in the shape of a sine function in the circumferential direction θ of the first filter container 400, so that the first rib 401 can cause the water or other liquid in the first filter container 400 to form turbulence while also preventing the first rib 401 from impacting the water or other liquid due to the presence of sharp bends and generating loud noise.

[0084] like Figure 6 As shown, in some embodiments of the present invention, the spacing d between the upper and lower edges of the first rib 401 in the axial direction z of the first filter container 400 is selected from any value between 3 mm and 10 mm, and in particular can be selected from any value between 5 mm and 8 mm, so that the first rib 401 can cause the water or other liquid 004 in the first filter container 400 to form turbulence while reducing the impact angle between the first rib 401 and the water or other liquid 004, thereby reducing the noise during the operation of the centrifugal extractor 001.

[0085] In some embodiments of the present invention, the distance d between the upper and lower edges of the first rib 401 in the axial direction z of the first filter container 400 can be 3 mm, 4.5 mm, 5 mm, 6 mm, 8 mm, 9 mm, 10 mm, etc.

[0086] like Figure 7 As shown, in some embodiments of the present invention, the thickness h of the first rib 401 extending inward from the first filter container 400 is selected from any value between 4 mm and 8 mm to ensure that the first rib 401 provides sufficient stirring force for the substance in the first filter container 400.

[0087] In some embodiments of the present invention, the thickness h of the first rib 401 extending inward from the first filter container 400 can be 4 mm, 4.5 mm, 5 mm, 6 mm, 7 mm, 8 mm, etc.

[0088] from Figure 7 As can be seen, in some embodiments of the present invention, the cross section of the first rib 401 is trapezoidal or conical, and the small end of the first rib 401 is in the radial direction r of the first filter container 400 (such as Figure 4 401). Those skilled in the art will appreciate that this arrangement of the first rib 401 ensures that solid matter within the first filter container 400 adheres closely to the first rib 401 and the first circumferential sidewall 410 under the action of centrifugal force, thereby preventing the formation of gaps between the solid matter, the first rib 401, and the first circumferential sidewall 410.

[0089] like Figures 4 to 7 As shown, in some embodiments of the present invention, the first rib 401 is provided at the bottom of the first filter container 400 to support the pressing block 600 , thereby limiting the lowest position of the pressing block 600 and preventing the pressing block 600 from being too low.

[0090] It should be noted that, in the present invention, the top and bottom of the first filter container 400 are two parts on the axial direction z of the first filter container 400, and there is no clear boundary between the two. Figure 7 The portion of the first filter container 400 located above the double-dashed line is divided into the top of the first filter container 400. Figure 7 The portion of the first filter container 400 shown in FIG. 4 below the double-dashed line is divided into the bottom of the first filter container 400 .

[0091] See below Figures 5 to 7 The first filter container 400 will be described in detail.

[0092] like Figures 5 to 7As shown, in some embodiments of the present invention, the first filter container 400 is generally barrel-shaped, and a plurality of first filter holes 411 are evenly distributed on the first circumferential side wall 410 of the first filter container 400 .

[0093] Furthermore, those skilled in the art may also, as needed, provide a first rib 401 on the outer side of the first circumferential sidewall 410. The first ribs 401 on the inner and outer sides of the first circumferential sidewall 410 may be the same or different. For example, the first rib 401 on the outer side of the first circumferential sidewall 410 may be spirally shaped.

[0094] See below Figure 4 、 Figure 5 、 Figures 8 to 10 The second filter container 500 will be described in detail.

[0095] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, a filter cavity 010 for filtering the liquid 004 is formed between the second filter container 500 and the bottom of the first filter container 400 to accommodate the liquid 004 (such as Figure 12 shown).

[0096] like Figure 5 、 Figures 8 to 10 As shown, at least one of the inner and outer sides of the second circumferential side wall 510 is provided with at least one second rib 501 to disturb the liquid 004 in contact with the second rib 501. In addition, the second rib 501 can be provided in a strip shape (e.g. Figure 5 、 Figures 8 to 10 as shown) or spiral, and any other feasible shapes.

[0097] like Figure 9 and Figure 10 As shown, in some embodiments of the present invention, multiple second ribs 501 may be provided only on the inner side of the second circumferential side wall 510. The number of the second ribs 501 may be 1, 2, 3, 6, 7, 8, 12, etc.

[0098] Of course, those skilled in the art may also provide multiple second ribs 501 only on the outer side of the second circumferential side wall 510 , or provide multiple second ribs 501 on both the inner and outer sides of the second circumferential side wall 510 as needed.

[0099] When a plurality of second convex ribs 501 are respectively provided on the inner and outer sides of the second circumferential side wall 510 , the second convex ribs 501 on the inner and outer sides may be the same or different.

[0100] like Figure 5 、 Figures 8 to 10As shown, in some embodiments of the present invention, the portion of the second filter container 500 that forms the outer wall of the filter cavity 010 is tapered to increase the filtration area of ​​the tapered portion. Specifically, the second circumferential sidewall 510 of the second filter container 500 slopes outward from bottom to top, allowing the liquid 004 to rise to the top of the second circumferential sidewall 510 under the action of centrifugal force. Furthermore, the second rib 501 extends from the bottom end of the second circumferential sidewall 510 to the top end of the second circumferential sidewall 510, so that the second rib 501 adapts to the tilt of the second circumferential sidewall 510.

[0101] like Figure 5 and Figure 10 As shown, in some embodiments of the present invention, the second filter container 500 also 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, so that the liquid 004 in the second filter container 500 can flow back to the first filter container 400 through the first filter hole 411 under the restriction of the annular plate 520.

[0102] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the ratio of the height of the second circumferential side wall 510 to the height of the first circumferential side wall 410 is selected from any value between 0.3 and 0.7 to reduce the climbing height of the liquid 004 in the second filter container 500 and reduce the overall height of the centrifugal extractor 001.

[0103] Specifically, the ratio of the height of the second circumferential side wall 510 to the height of the first circumferential side wall 410 may be 0.3, 0.4, 0.5, 0.56, 0.6, 0.7, etc.

[0104] like Figure 5 、 Figures 8 to 10 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.

[0105] like Figure 4 and Figure 5 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.

[0106] Furthermore, the inner annular portion 530 and the first circumferential sidewall 410 of the first filter container 400 may be interference-fitted.

[0107] like Figure 4 and Figure 5 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.

[0108] like Figure 4 and Figure 5 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.

[0109] like Figures 8 and 9 As shown, in some embodiments of the present invention, the distribution density of the second filter holes 511 at the top of the second circumferential side wall 510 is less than the distribution density at the bottom of the second circumferential side wall 510, so as to prevent the liquid 004 at the top of the second circumferential side wall 510 from being lost quickly and unable to accumulate and flow back to the first filter container 400.

[0110] Furthermore, the distribution density of the second filter holes 511 gradually increases from the top side to the bottom side of the second circumferential sidewall 510 .

[0111] Alternatively, in other embodiments of the present invention, those skilled in the art may also, as needed, distribute all the second filter holes 511 at the bottom of the second circumferential side wall 510 to prevent the liquid 004 at the top of the second circumferential side wall 510 from being lost and unable to accumulate and flow back to the first filter container 400.

[0112] It should be noted that, in the present invention, the top and bottom of the second circumferential side wall 510 are two parts of the second circumferential side wall 510 in the axial direction z, and there is no clear boundary between the two. Figure 10 The portion of the second circumferential side wall 510 located above the double-dotted line is divided into the top of the second circumferential side wall 510. Figure 10 The portion of the second circumferential side wall 510 shown in FIG. 5 , which is located below the double-dashed line, is divided into the bottom portion of the second circumferential side wall 510 .

[0113] In other embodiments of the present invention, those skilled in the art may further, as needed, make the diameter of the top second filter holes 511 smaller than the diameter of the bottom second filter holes 511. For example, the diameter of the second filter holes 511 may gradually increase from the top side to the bottom side of the second circumferential sidewall 510.

[0114] Furthermore, in some embodiments of the present invention, the ratio of the pore size of the first filter hole 411 to the pore size of the second filter hole 511 is greater than 1 and less than or equal to 3, so as to ensure that the flow capacity of all the second filter holes 511 on the second filter container 500 is less than the flow capacity of all the first filter holes 411 in the area corresponding to the second circumferential side wall 510 on the first filter container 400, thereby preventing the liquid 004 in the second filter container 500 from being quickly thrown out.

[0115] Furthermore, the ratio of the aperture of the first filter hole 411 to the aperture of the second filter hole 511 is greater than 1 and less than or equal to 2.

[0116] For example, the ratio of the aperture of the first filter hole 411 to the aperture of the second filter hole 511 may be 1.1, 1.5, 1.7, 1.9, 2, 2.5, 3, etc.

[0117] like Figure 1 、 Figure 4 、 Figure 5 and Figure 11 As shown, in some embodiments of the present invention, the pressing block 600 is configured in a ring shape so that substances (as described above) can be put into the first filter container 400 through the hollow area of ​​the pressing block 600 .

[0118] from Figure 4 、 Figure 5 and Figure 11 As can be seen in the figure, in some embodiments of the present invention, the thickness h 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 substances placed on the top surface of the pressing block 600 slide down the funnel surfaces under the action of their own gravity into the first filter container 400. Furthermore, 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, thereby facilitating its use.

[0119] Refer to the following Figure 12 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 12 The first rib 401 and the first filter hole 411 are hidden in the figure to facilitate intuitive observation by those skilled in the art.

[0120] like Figure 12 As shown, after the object to be extracted 002 is placed in the first filter container 400, 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 object to be extracted 002 in the first filter container 400 and causing it to adhere to the first circumferential side wall 410 of the first filter container 400.

[0121] Continue reading Figure 12 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.

[0122] Continue reading Figure 12 As the first filter container 400 rotates, the liquid 004 in the first filter container 400 passes through the first filter hole 411 and is thrown into the second filter container 500. A portion of the liquid 004 in the second filter container 500 is thrown into the liquid storage container 200 through the second filter hole 511 (as shown in FIG. Figure 12 The other part of the liquid 004 in the second filter container 500, under the action of centrifugal force, climbs up along the inclined second circumferential side wall 510 to the annular plate 520, and is squeezed back into the first filter container 400 as the liquid 004 below the annular plate 520 continues to increase (as shown by the dotted line with an arrow on the bottom side). Figure 12 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.

[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] 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.

[0125] 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.

[0126] After the centrifugal extractor 001 is used, the motor 310 can be rotated forward and reverse alternately (for example, the forward and reverse rotation ratio of the motor 310 is 5:3) so that the block-shaped object to be extracted 002 is cut into multiple pieces and broken up by the first rib 401 under the action of inertia, making it easier for the user to take it out.

[0127] After removing the object to be extracted 002, the user can add sufficient clean water to the first filter container 400 and then start the motor 310, rotating it in one direction, or alternately in forward and reverse rotation. As the first and second ribs 401, 501 rotate with the first and second filter containers 400, 500, they disturb the clean water within them, creating turbulent flow. Compared to laminar flow, turbulent flow has a greater impact on the first and second filter containers 400, 500, thereby enhancing the cleansing effect of the clean water on the first and second filter containers 400, 500 and reducing the difficulty of cleaning the extraction equipment.

[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 has a self-cleaning function, 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.
