Description

Technical Field

[0001] The utility model belongs to the technical field of beverage extraction equipment, and specifically provides a centrifugal extraction machine. 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] To achieve the above-mentioned object, the present invention provides a centrifugal extractor, comprising:

[0006] body;

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

[0008] a driving device, mounted on the fuselage;

[0009] a first filtering container, drivingly connected to the driving device so as to be driven to rotate by the driving device, thereby extracting the substance to be extracted therein by centrifugation;

[0010] A water sprinkling container is arranged in the first filter container and is connected to the driving device. A plurality of water sprinkling holes are provided on the peripheral wall of the water sprinkling container so that the liquid in the water sprinkling container is sprinkled onto the object to be extracted by centrifugation and is thrown out by the first filter container into the liquid storage container.

[0011] Optionally, the diameter of the watering hole is selected from any value between 0.05 mm and 2 mm.

[0012] Optionally, the diameter of the watering hole is selected from any value between 0.15 mm and 0.25 mm.

[0013] Optionally, the plurality of watering holes are evenly distributed in the circumferential direction of the watering container; and / or the plurality of watering holes are evenly distributed in the axial direction of the watering container.

[0014] Optionally, the watering container is connected to the first filter container so as to be drivingly connected to the driving device via the first filter container.

[0015] Optionally, one of the bottom walls of the watering container and the first filter container is provided with a protrusion structure, and the other is provided with a groove structure adapted to the protrusion structure, and the protrusion structure is inserted into the groove structure to achieve the connection between the watering container and the first filter container.

[0016] Optionally, the protrusion structure is provided on the bottom wall of the first filtering container, the groove structure is provided on the bottom wall of the watering container, and the protrusion structure and the groove structure are plugged together in a detachable manner.

[0017] Optionally, the watering container includes a large diameter portion and a small diameter portion located on the top side of the large diameter portion; the watering hole is formed on the peripheral wall of the large diameter portion, and the water inlet of the watering container is formed at one end of the small diameter portion away from the large diameter portion.

[0018] Optionally, the watering container further includes a tapered ring portion provided between the large diameter portion and the small diameter portion; and / or, the watering container is provided with a cover for blocking the water inlet.

[0019] Optionally, the centrifugal extractor further comprises an annular pressure block arranged between the first filter container and the small diameter portion; and / or, the centrifugal extractor further comprises a second filter container arranged between the liquid storage container and the first filter container, and the second filter container is drivingly connected to the driving device.

[0020] Based on the foregoing description, those skilled in the art will understand that, in the aforementioned technical solution of the present invention, by configuring a first filter container that is drivably connected to a drive device, disposing a watering container that is drivably connected to the drive device within the first filter container, and providing a plurality of watering holes on the peripheral wall of the watering container, the watering container can centrifugally spray the liquid within toward the material to be extracted, thereby fully contacting the material to be extracted, and thereby enabling the first filter container to perform centrifugal extraction of the material to be extracted by rotating. During centrifugal extraction, it is easier to throw the effective substances in the material to be extracted out of the first filter container, so that the centrifugal extractor of the present invention improves the completeness of its extraction of the material to be extracted.

[0021] Moreover, compared to directly injecting liquid into the first filter container to quickly soak the object to be extracted, the utility model uses a water sprinkling container to throw the liquid toward the object to be extracted, which effectively avoids the agglomeration and channel effect caused by the object to be extracted receiving too much liquid too quickly at the same time, thereby effectively ensuring the extraction efficiency of the object to be extracted.

[0022] Furthermore, by setting the diameter of the watering hole to any value between 0.05 mm and 2 mm, and in particular to any value between 0.15 mm and 0.25 mm, the liquid in the watering container flows out more slowly or is difficult to flow out under its own gravity, thereby avoiding the liquid in the watering container flowing out in large quantities before the watering container rotates, affecting the effect of the watering container in uniformly spraying the liquid onto the object to be extracted.

[0023] Furthermore, by evenly distributing the plurality of watering holes in the axial direction of the watering container, the watering container can evenly spray liquid on the object to be extracted in the axial direction thereof, so that the object to be extracted evenly receives the liquid.

[0024] Furthermore, by making the watering container and the first filter container detachably connected, the watering container can also be disassembled, which is convenient for users to clean.

[0025] Furthermore, by arranging an annular pressing block between the first filter container and the small diameter portion of the watering container, it is possible to prevent the liquid in the first filter container from being thrown out and to increase the stability of the watering container during rotation.

[0026] 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.

[0053] 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.

[0054] 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.

[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 4 As shown, in some embodiments of the present invention, the centrifugal extractor 001 innovatively uses centrifugal extraction technology and includes a body 100, a liquid storage container 200, a driving device 300, a first filter container 400, an optional second filter container 500, an optional annular pressing block 600, a water sprinkling container 700 and an optional cover 800.

[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, the second filter container 500, and the watering container 700, 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, the second filter container 500, and the watering container 700 can be installed, those skilled in the art may also configure the housing 100 into any other feasible shape, such as a hollow barrel-shaped member, as needed. Alternatively, those skilled in the art may omit the housing 100 as needed.

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

[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 circumferential side wall of the first filter container 400 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 14As shown) for centrifugal extraction, and the extracted target substance 003 (as shown Figure 14 as shown) passes through the first filter hole 411.

[0061] The circumferential sidewall of the second filter container 500 is designated as a second circumferential sidewall 510 and 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 second circumferential sidewall 510 can be inclined outward from bottom to top, so that the liquid 004 rises to the top of the second circumferential sidewall 510 under the action of centrifugal force, thereby increasing the effective filtration area of ​​the second circumferential sidewall 510 for the liquid 004 and improving the filtration efficiency of the second filter container 500 for the liquid 004.

[0062] In addition, in other embodiments of the present invention, those skilled in the art may also omit the second filtering container 500 as needed. However, doing so may reduce the filtering effect and the taste of the final solution.

[0063] The annular pressing block 600 is arranged along the rotation axis X (eg Figure 4 As shown in FIG. 4 , the first filter container 400 is slidably disposed in the first filter container 400 to compress the object to be extracted 002 in the first filter container 400 and prevent the object to be extracted 002 from being thrown out of the first filter container 400 .

[0064] In addition, in other embodiments of the present invention, those skilled in the art may also omit the annular pressing block 600 as needed. However, doing so may cause the object to be extracted 002 and the liquid 004 in the first filter container 400 to be thrown out.

[0065] Among them, the water sprinkling container 700 is arranged in the first filter container 400 and is driven and connected to the driving device 300. A plurality of water sprinkling holes 701 are provided on the peripheral wall of the water sprinkling container 700, so that the water sprinkling container 700 sprinkles the liquid 004 therein onto the object to be extracted 002 by centrifugation and is thrown out by the first filter container 400 into the liquid storage container 200.

[0066] Furthermore, the diameter of the watering hole 701 is selected from any value between 0.05 mm and 2 mm, and in particular, the diameter of the watering hole 701 can be selected from any value between 0.15 mm and 0.25 mm, for example, it can be 0.05 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.2 mm, 0.22 mm, 0.25 mm, etc.

[0067] Those skilled in the art will appreciate that by setting the diameter of the watering hole 701 to any value between 0.05 mm and 2 mm, and in particular to any value between 0.15 mm and 0.25 mm, the liquid 004 in the watering container 700 flows out more slowly or has difficulty in flowing out under its own gravity, thereby avoiding the liquid 004 in the watering container 700 flowing out in large quantities before the watering container 700 rotates, thereby affecting the effect of the watering container 700 in uniformly sprinkling the liquid onto the object to be extracted 002.

[0068] The cover 800 is used to seal the watering container 700 to prevent the liquid 004 in the watering container 700 from being thrown out during the rotation of the watering container 700.

[0069] In addition, in other embodiments of the present invention, those skilled in the art may also omit the cover 800 as needed.

[0070] Those skilled in the art will appreciate that the present invention, by configuring a first filter container 400 that is drivably connected to the drive device 300, disposing a watering container 700 within the first filter container 400 that is drivably connected to the drive device 300, and providing a plurality of watering holes 701 on the peripheral wall of the watering container 700, enables the watering container 700 to centrifugally spray its liquid 004 toward the material to be extracted 002, thereby fully contacting the material to be extracted 002. This allows the first filter container 400 to perform centrifugal extraction of the material to be extracted 002 by rotating. During centrifugal extraction, the effective substances in the material to be extracted 002 are more easily ejected from the first filter container 400. Therefore, the centrifugal extractor 001 of the present invention improves the completeness of the extraction of the material to be extracted 002.

[0071] Moreover, compared to directly injecting the liquid 004 into the first filter container 400 to quickly soak the object to be extracted 002, the present invention uses the water sprinkling container 700 to throw the liquid 004 toward the object to be extracted 002, which effectively avoids the agglomeration and channel effect caused by the object to be extracted 002 receiving too much liquid 004 too quickly at the same time, thereby effectively ensuring the extraction efficiency of the object to be extracted 002.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] Target substance 003 can be a water-soluble substance in the object to be extracted 002. Liquid 004 can be hot, room temperature, or cold water, and can be pure water, tap water, mineral water, or a solution containing a specific substance (e.g., sugar, milk, flavoring, etc.). For example, liquid 004 in watering container 700 can be water, while liquid 004 in liquid storage container 200 can be a solution containing a portion of the object to be extracted 002.

[0076] 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 .

[0077] 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.

[0078] 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.

[0079] 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 protrusion (not labeled) is provided on the peripheral wall of the liquid storage container 200, and a slot (not labeled) is provided on the body 100 to match the protrusion. The protrusion is inserted into the slot, thereby achieving circumferential fixation of the liquid storage container 200 to the body 100. A hanging ear (not labeled) may also be provided on the side of the liquid storage container 200 away from the protrusion. The body 100 is provided with a corresponding slot 421 (not labeled), and the hanging ear is inserted into the slot 421 to further achieve circumferential fixation of the liquid storage container 200 to the body 100.

[0080] 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.

[0081] 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 .

[0082] 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.

[0083] 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.

[0084] 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 .

[0085] 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.

[0086] 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.

[0087] 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 .

[0088] 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 and the second filter container 500 are riveted, welded, or screwed, and the first filter container 400 and the second filter container 500 are snap-fitted, welded, or screwed.

[0089] 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 fixation of the two parts.

[0090] 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.

[0091] like Figure 5As shown, in some embodiments of the present invention, the first filter container 400 further includes a first top plate 420 extending outward, and a card slot 421 with an opening facing downward is provided on the first top plate 420 .

[0092] from Figure 5 As can be seen from the figure, the first top plate 420 is located on the top side of the first circumferential side wall 410, and the clamping groove 421 is an annular groove and can be formed by a stamping process.

[0093] Continue reading Figure 5 In some embodiments of the present invention, the first filter container 400 may further include a first bottom plate 430 located at the bottom side of the first circumferential side wall 410 to prevent the extract 002 in the first filter container 400 from leaking out.

[0094] like Figure 6 As shown, in some embodiments of the present invention, the second filter container 500 further includes an inner ring portion 530, a second top plate 540, an outer ring portion 550, and a second bottom plate 560. The bottom end of the inner ring portion 530 is connected to the annular plate 520, the top end of the inner ring portion 530 is connected to the inner edge of the second top plate 540, the outer edge of the second top plate 540 is connected to the top end of the outer ring portion 550, and the second bottom plate 560 is located on the bottom side of the second circumferential side wall 510 and is connected to the second circumferential side wall 510.

[0095] Continue reading Figure 6 In some embodiments of the present invention, the second bottom plate 560 is provided with rivet holes 561, so that the second filter container 500 can be riveted to the connector 320 through the rivet holes 561. Of course, those skilled in the art can also use other connection methods to securely connect the second filter container 500 to the connector 320 as needed. For details, please refer to the above description of the connector 320.

[0096] like Figure 4 and Figure 7 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.

[0097] Furthermore, the inner annular portion 530 and the first circumferential sidewall 410 of the first filter container 400 may be interference-fitted.

[0098] like Figure 6 As shown, an upwardly protruding rib 541 is provided on the second top plate 540 of the second filter container 500 , and the rib 541 is adapted to fit into the slot 421 on the first filter container 400 .

[0099] Continue reading Figure 4 and Figure 7 In some embodiments of the present invention, the rib 541 is embedded in the slot 421 to fix the first filter container 400 and the second filter container 500 together.

[0100] In some embodiments of the present invention, the first bottom plate 430 of the first filter container 400 and the second bottom plate 560 of the second filter container 500 may or may not abut against each other.

[0101] like Figures 7 to 10 As shown, in some embodiments of the present invention, the annular pressing block 600 includes a body 610 and a magnet 620 mounted on the body 610 , so that the annular pressing block 600 is attracted to the peripheral wall of the first filter container 400 through the magnet 620 .

[0102] The body 610 has an annular groove 611 on its circumferential sidewall, and the cross section of the annular groove 611 perpendicular to its extension direction may be rectangular. Of course, those skilled in the art may also set the cross section to any feasible shape such as C-shape, U-shape, or semicircle as needed.

[0103] The magnet 620 is configured to be annular in shape to match the annular groove 611 and is embedded in the annular groove 611 .

[0104] To facilitate the installation of magnet 620, those skilled in the art may also, as needed, configure body 610 into two parts, which can be connected together by threads, screws, clamping, etc. The annular groove 611 is defined by the two parts. When installing magnet 620, magnet 620 is first mounted on one of the two parts, and then the other part is fixed to the first part, thereby clamping magnet 620 between the two parts.

[0105] In addition, in other embodiments of the present invention, those skilled in the art can also set the annular groove 611 and the magnet 620 to any other feasible shape as needed. The details are as follows:

[0106] In example 1, an annular groove 611 is provided on the circumferential side wall of the body 610 , and there are multiple magnets 620 , which are evenly spaced and distributed in the annular groove 611 .

[0107] In the second example, an annular groove 611 is provided on the circumferential side wall of the body 610 , and the magnets 620 are two semicircular components, both of which are provided in the annular groove 611 .

[0108] Example 3: A plurality of grooves distributed at equal intervals are provided on the circumferential side wall of the main body 610 , and a magnet 620 is embedded in each groove.

[0109] In the present invention, the magnet 620 can be any feasible magnet such as an Alnico magnet, a ferrite magnet, or a NdFeB magnet.

[0110] In the present invention, the main body 610 can be made of stainless steel, alloy, organic material and the like.

[0111] Of course, those skilled in the art may also configure the annular pressing block 600 as a whole and configure the annular pressing block 600 as a magnet as needed.

[0112] In the present invention, the first filter container 400 is made of a material that can be attracted by the magnet 620 , such as iron, stainless steel, etc.

[0113] like Figure 11 As shown, in other embodiments of the present invention, those skilled in the art may also, as needed, make the annular pressing block 600 further include a protective cover 630 , and sleeve the protective cover 630 on the circumferential side wall of the body 610 to hide the magnet 620 .

[0114] It will be understood by those skilled in the art that the protective cover 630 effectively prevents the debris generated when the magnet 620 breaks from being mixed into the object to be extracted 002 and thrown out into the liquid storage container 200 .

[0115] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 、 Figure 12 and Figure 13 As shown, in some embodiments of the present invention, the plurality of watering holes 701 are evenly distributed in the circumferential direction of the watering container 700, and the plurality of watering holes 701 are evenly distributed in the axial direction of the watering container 700. Figure 4 The axis X indicated by the mid-dash line is parallel.

[0116] Those skilled in the art will appreciate that by evenly distributing the plurality of watering holes 701 in the axial direction of the watering container 700 , the watering container 700 can evenly spray the liquid 004 on the object to be extracted 002 in the axial direction, so that the object to be extracted 002 evenly receives the liquid 004 .

[0117] like Figure 12 and Figure 13 As shown, in some embodiments of the present invention, a water filling port 702 is provided on the top of the watering container 700 , so that a user can fill water or other liquids 004 into the watering container 700 through the water filling port 702 .

[0118] like Figure 4 、 Figure 7 and Figure 14As shown, the water inlet 702 is adapted to the cover 800 .

[0119] In some embodiments of the present invention, the cover 800 can be made of elastic materials such as rubber, silicone, etc., so that the cover 800 can seal the water inlet 702. Figure 4 、 Figure 7 and Figure 14 As can be seen in the figure, the cover 800 is provided with an annular groove adapted to the peripheral wall of the water inlet 702 to ensure the stability of the connection between the cover 800 and the watering container 700 and prevent the cover 800 from being accidentally separated from the watering container 700.

[0120] like Figure 5 、 Figures 12 to 14 As shown, in some embodiments of the present invention, the watering container 700 is connected to the first filter container 400, so as to be driven and connected to the driving device 300 by means of the first filter container 400. Specifically, a protrusion structure 440 is provided on the bottom wall of the first filter container 400, and a groove structure 703 is provided on the bottom wall of the watering container 700. The protrusion structure 440 is inserted into the groove structure 703, thereby achieving the connection between the watering container 700 and the first filter container 400.

[0121] In addition, in other embodiments of the present invention, those skilled in the art may also dispose the protrusion structure 440 on the bottom side of the bottom wall of the watering container 700 and dispose the groove structure 703 on the bottom wall of the first filter container 400 as needed.

[0122] Alternatively, those skilled in the art may also connect the watering container 700 and the first filter container 400 together in any other feasible manner as needed, such as welding, riveting, clamping, screwing, etc. Alternatively, the watering container 700 and the first filter container 400 may be integrally formed.

[0123] Furthermore, in some embodiments of the present invention, the protrusion structure 440 and the groove structure 703 are plugged together in a detachable manner, so that the watering container 700 can be disassembled, thereby facilitating cleaning by the user.

[0124] like Figure 7 、 Figure 12 and Figure 13 As shown, in some embodiments of the present invention, the watering container 700 includes a large diameter portion 710 and a small diameter portion 720 located on the top side of the large diameter portion 710. Furthermore, the watering hole 701 is formed on the peripheral wall of the large diameter portion 710, and the water inlet 702 of the watering container 700 is formed at one end of the small diameter portion 720 away from the large diameter portion 710.

[0125] Those skilled in the art will appreciate that the watering container 700 can accommodate a sufficient amount of liquid 004 through the large diameter portion 710 , and can also be grasped by a user through the small diameter portion 720 for easy disassembly.

[0126] Continue reading Figure 7 、 Figure 12 and Figure 13 In some embodiments of the present invention, the watering container 700 may further include a conical ring portion 730 disposed between the large diameter portion 710 and the small diameter portion 720 , so as to adapt to the bottom surface of the annular pressing block 600 through the conical ring portion 730 and optimize the appearance of the watering container 700 .

[0127] from Figure 7 As can be seen in FIG, the annular pressing block 600 is located between the first filter container 400 and the small diameter portion 720 , and can abut against the tapered ring portion 730 .

[0128] Refer to the following Figure 4 and 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 Part of the structure of the first filter container 400 and the watering container 700 is hidden.

[0129] like Figure 4 and Figure 14 As shown, after the object to be extracted 002 is placed in the first filter container 400, the user can adjust the height of the annular pressing block 600 according to the amount of the object to be extracted 002. The motor 310 is then started. The motor 310 drives the first filter container 400 and the second filter container 500 to rotate, 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 sidewall 410 of the first filter container 400. The motor 310 is then paused.

[0130] Continue reading Figure 4 and Figure 14 Fill the water container 700 with water and then place the cover 800 over the water inlet 702 of the water container 700. Then, start the motor 310, causing the liquid 004 to be ejected from the water hole 701 onto the object to be extracted 002 as the water container 700 rotates. Centrifugal force causes the liquid 004 to pass through the object to be extracted 002, 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.

[0131] Continue reading Figure 4 and Figure 14As 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 out to the second filter container 500 (eg Figure 14 The liquid 004 in the second filter container 500 is ejected into the liquid storage container 200 through the second filter holes 511. During this process, a portion of the liquid 004 in the second filter container 500, under the action of centrifugal force, rises along the inclined second circumferential sidewall 510 and is evenly spread across the entire second circumferential sidewall 510, thereby improving the filtering performance of the second filter container 500.

[0132] 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 .

[0133] 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.

[0134] 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.

[0135] In summary, the centrifugal extractor 001 of the present invention not only improves the extraction efficiency of the material 002 through centrifugation, but also enables the material 002 to evenly receive the liquid 004 through the water spray container 700, ensuring that every portion of the material 002 is extracted. Furthermore, the annular pressure block 600 and the cover 800 prevent the liquid 004 from being thrown out.

[0136] Thus far, the technical solutions of the present invention have been described in conjunction with the above 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 in the above 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 will fall within the scope of protection of the present invention.
