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 powdered target substances such as coffee by means of hot water brewing, cooking, etc. to obtain the final drinking solution.

[0003] With the advancement of technology, some extraction equipment has the function of cold extraction, which can extract powdered target objects such as coffee by cold extraction. Cold extraction is generally to soak powdered target objects such as coffee for a long time at room temperature or below room temperature to extract the final drinking solution.

[0004] During the cold extraction process of powdered target materials such as coffee, part of the solution will be absorbed by the powdered target materials such as coffee, and due to long-term contact with the powdered target materials such as coffee, the concentration of this part of the solution is relatively high. However, due to this, it is difficult to separate this part of the solution from the powdered target materials such as coffee, and the powdered target materials such as coffee cannot be completely extracted, resulting in low extraction efficiency.

For example, the terms "install", "connect", "connect" and "fix", unless otherwise specifically described, can specifically be any feasible connection form such as bolt connection, screw connection, welding, plug-in, riveting, melting, and clamping.

[0054] like Figures 1 to 3 As shown, in some embodiments of the present invention, the centrifugal extractor 001 includes a body 100 , a driving device 200 , a filtering container 300 and a hollow cap 800 .

[0055] from Figure 3 It can be seen that in some embodiments of the present invention, the driving device 200 is installed on the fuselage 100.

[0056] like Figures 3 to 6 As shown, in some embodiments of the present invention, a plurality of filter holes 301 are provided on the circumferential side wall of the filter container 300, and the filter container 300 is connected to the driving device 200 to be driven to rotate by the driving device 200, so that the powdered target 002 (such as Fig.17 and Fig.18 As shown in the figure, the powdered target 002 flows toward the powdered target 002 under the action of centrifugal force and forms a solution, and then the solution is separated from the powdered target 002 under the action of centrifugal force and thrown out of the filter container 300 through the filter hole 301.

[0057] like Figures 1 to 3 As shown, in some embodiments of the present invention, the cap 800 is detachably mounted on the filter container 300 so as to add liquid to the filter container 300 through the cap 800 .

[0058] It is understood by those skilled in the art that by driving the filter container 300 to rotate by the driving device 200, the powdered target 002 put into the filter container 300 can be attached to the circumferential side wall of the filter container 300 under the action of centrifugal force, and the liquid entering the filter container 300 flows toward the powdered target 002 under the action of centrifugal force to form a solution, and then the solution is separated from the powdered target 002 under the action of centrifugal force and thrown out of the filter container through the filter hole 301. Therefore, the solution of the utility model can be separated from the powdered target 002 under the action of centrifugal force, so that the powdered target 002 absorbs less solution, and the extraction efficiency of the powdered target 002 is improved. The setting of the cap 800 makes it convenient for users to add liquid to the filter container.

[0059] It should be noted that, in the present invention, the powdered target 002 includes coffee powder and / or tea powder. For example, the powdered target 002 can be coffee powder or tea powder, or a mixture of coffee powder and tea powder.

[0060] Of course, those skilled in the art may also make the powdery target 002 include any other feasible powdery substances, such as soybean powder, mung bean powder, cocoa powder, etc., as needed.

[0061] It should also be noted that in the present invention, the liquid can be hot water, room temperature water or cold water in terms of temperature, and can be pure water, tap water, mineral water or water dissolved with specific substances (such as sugar, milk, flavors, etc.) in terms of composition. The solution is the above liquid in which the powdered target 002 is dissolved.

[0062] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the centrifugal extractor 001 may further include a pump bucket 400 disposed outside the filter container 300. The pump bucket 400 is used to receive the solution thrown out from the filter container 300.

[0063] like Figure 3 , Figures 7 to 10 As shown, in some embodiments of the present invention, the pump bucket 400 is provided with a spiral channel 401 formed on the barrel wall thereof, a channel inlet 402 located at the bottom end of the spiral channel 401, and a channel outlet 403 located at the top end of the spiral channel 401. The pump bucket 400 is drivingly connected to the driving device 200, so as to be driven to rotate by the driving device 200, so that the solution in the pump bucket 400 enters the spiral channel 401 through the channel inlet 402 under the action of centrifugal force, and is then lifted by the spiral channel 401 to the channel outlet 403 and flows back to the filter container 300.

[0064] Those skilled in the art will appreciate that, in some embodiments of the present invention, when the pump bucket 400 rotates, the solution therein (the solution thrown out from the filter container 300) can be pumped back into the filter container 300 through the spiral channel 401 provided thereon, thereby achieving a circulation and re-extraction of the powdered target object 002 by the solution, thereby improving the extraction efficiency and the final quality of the solution, and shortening the soaking time of the powdered target object 002.

[0065] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the driving device 200 includes a motor 210 and a connector 220. The motor 210 is fixedly connected to the body 100 through its housing, and the motor 210 is fixedly connected to the connector 220 through its rotating shaft, and the connector 220 is fixedly connected to the filter container 300 and the pump bucket 400, so that the motor 210 drives the filter container 300 and the pump bucket 400 to rotate through the connector 220.

[0066] The connector 220 may be any feasible structure such as a plate-like structure, a columnar structure, a Y-shaped structure, a triangular structure, etc. The connector 220 is provided with a shaft hole (not marked in the figure) matching the shaft of the motor 210, so as to realize the fixed connection between the connector 220 and the shaft of the motor 210 through the shaft hole. Alternatively, the connector 220 is provided with a connecting shaft, and the connecting shaft is fixedly connected to the shaft of the motor 210 through a coupling.

[0067] Alternatively, those skilled in the art may also connect the connector 220 and the rotating shaft of the motor 210 together by any other feasible connection method, such as welding, bolt connection, flange connection, etc., as needed.

[0068] Furthermore, the connector 220 is provided with a plurality of connection holes, and the filter container 300 and the pump bucket 400 are also respectively provided with a plurality of connection holes, so that the filter container 300 and the pump bucket 400 are respectively fixed to the connector 220 by means of bolts matching the connection holes of the three. Alternatively, one of the filter container 300 and the pump bucket 400 is fixed to the connector 220, and then the one is connected to the other of the filter container 300 and the pump bucket 400 by interference connection, welding, riveting, clamping, bolt connection, etc.

[0069] In addition, in other embodiments of the utility model, those skilled in the art may also set the driving device 200 to any other feasible form as needed, for example, the driving device 200 only includes the motor 210, and the rotating shaft of the motor 210 is directly fixedly connected to at least one of the filter container 300 and the pump bucket 400. When the rotating shaft of the motor 210 is only fixedly connected to one of the filter container 300 and the pump bucket 400, the one is connected to the other of the filter container 300 and the pump bucket 400 by interference connection, welding, riveting, clamping, bolt connection, etc.

[0070] like Figure 3 As shown, the filtration container 300 is located between the channel inlet 402 and the channel outlet 403 in the axial direction thereof, so that the solution ejected from the filtration container 300 can flow toward the channel inlet 402 and the filtration container 300 receives the solution flowing out from the channel outlet 403 .

[0071] It should be noted that, in the description of the present invention, “axial direction” may be a direction parallel to the rotation axis of the filter container 300 and / or the rotation axis of the pump bucket 400 .

[0072] like Figures 4 to 6 As shown, in some embodiments of the present invention, the radial cross section of the filter container 300 perpendicular to its axial direction is circular, so as to improve the dynamic balance of the filter container 300 during rotation, so that the filter container 300 has good rotation performance during rotation.

[0073] In addition, in other embodiments of the present invention, those skilled in the art may also shape the radial cross-section of the filter container 300 perpendicular to its axial direction into a plum blossom shape, a polygon (such as a hexagon, an octagon, a dodecagon, etc.), a rectangle, etc. as needed.

[0074] like Figures 4 to 6 As shown, in some embodiments of the present invention, the filter container 300 includes a receiving portion 310 provided with a filter hole 301 and an annular plate portion 320 located on the top side of the receiving portion 310, so as to stop the powdered target 002 in the receiving portion 310 through the annular plate portion 320 to prevent the powdered target 002 in the receiving portion 310 from moving upward under the action of centrifugal force.

[0075] It is understood by those skilled in the art that when the filter container 300 rotates, the powdered target 002 in the filter container 300 will be close to the circumferential side wall of the filter container 300 under the action of centrifugal force. When there are more powdered targets 002 in the filter container 300, the powdered targets 002 on the side close to the axis of the filter container 300 (hereinafter referred to as the inner side) in the radial direction will continuously squeeze the powdered targets 002 on the side away from the axis of the filter container 300 (hereinafter referred to as the outer side), so that the powdered targets 002 on the outer side are flattened, thereby becoming longer in the axial direction. The existence of the annular plate portion 320 can just prevent the powdered targets 002 on the outer side from becoming longer in the axial direction. If there is no annular plate portion 320, the powdered targets 002 at the top of the filter container 300 will be thinner, resulting in a large difference in the thickness of the powdered targets 002 in the filter container 300.

[0076] Continue reading Figures 4 to 6 In some embodiments of the present invention, a plurality of liquid permeable holes 302 may be further provided on the annular plate portion 320 , so that the filter container 300 receives the solution flowing out of the channel outlet 403 through the liquid permeable holes 302 .

[0077] Those skilled in the art will appreciate that the liquid permeable hole 302 can ensure that the solution flows back to the receiving portion 310 while allowing the powdered target 002 in contact with the annular plate portion 320 to receive the solution (if the solution in the receiving portion 310 is thrown toward the powdered target 002 by centrifugal force, this part of the powdered target 002 will have difficulty in contacting the solution due to its higher position).

[0078] Continue reading Figures 4 to 6 In some embodiments of the present invention, the filter container 300 may further include a neck 330 located on the top side of the annular plate portion 320 and connected to the inner end of the annular plate portion 320 , so that the filter container 300 receives the powdered target 002 through the neck 330 .

[0079] Those skilled in the art will appreciate that by providing the filter container 300 with the neck 330 , the inlet at the top of the filter container 300 is high enough to facilitate the user to put the powdered target 002 into the filter container 300 .

[0080] Continue reading Figures 4 to 6 In some embodiments of the present invention, the filter container 300 may further include a flange 340 located on the top side of the neck 330, so as to improve the structural strength of the neck 330 through the flange 340 and prevent the neck 330 from being deformed in the radial direction.

[0081] In addition, in other embodiments of the present invention, those skilled in the art may also configure the filter container 300 to any other feasible shape as needed, for example, omitting the flange 340, or omitting the neck 330 and the flange 340, or configuring the filter container 300 to be in the shape of a wine bottle.

[0082] like Figures 7 to 11 As shown, in some embodiments of the present invention, the pump bucket 400 includes a bucket body 410 and a spiral member 420 .

[0083] Continue reading Figures 7 to 11 The channel inlet 402 and the channel outlet 403 are both formed on the barrel body 410. In addition, a first annular cavity 4101 is defined in the circumferential side wall of the barrel body 410, and the first annular cavity 4101 is communicated with the channel inlet 402 and the channel outlet 403 respectively.

[0084] like Fig.10 As shown, the spiral member 420 is arranged in the first annular cavity 4101 , so that the peripheral wall of the first annular cavity 4101 and the spiral member 420 together define a spiral channel 401 .

[0085] Furthermore, although not shown in the drawings, the barrel body 410 includes at least two parts, so that after the spiral member 420 is installed on one of the two parts, the other part is installed on the one part.

[0086] It will be understood by those skilled in the art that the spiral channel 401 is defined by the combination of the barrel body 410 and the spiral member 420 , which facilitates the production and processing of the pump barrel 400 .

[0087] In addition, those skilled in the art may also configure the barrel body 410 and the spiral member 420 as a whole as needed, for example, by injection molding, casting, or 3D printing.

[0088] like Fig.10 and Fig.11 As shown, in some embodiments of the present invention, the bottom wall of the barrel 410 defines a second annular cavity 4102 communicating with the first annular cavity 4101 . Furthermore, the channel inlet 402 is a plurality of through holes formed on the top wall of the second annular cavity 4102 .

[0089] Those skilled in the art will appreciate that by defining the bottom wall of the barrel body 410 with a second annular cavity 4102 connected to the spiral channel 401, and configuring the channel inlet 402 to be a plurality of through holes formed on the top wall of the second annular cavity 4102, the solution in the barrel body 410 can flow entirely to the spiral channel 401 via the channel inlet 402 and the second annular cavity 4102, and then flow to the filter container 300 again to enter the next cycle.

[0090] It should be noted that the bottom wall of the barrel body 410 shown in the figure is an annular structure to avoid the connector 220. When the aforementioned connection between the driving device 200 and the filter container 300 and the pump bucket 400 can be achieved (see the above text for details), those skilled in the art can also set the bottom wall of the barrel body 410 to any other feasible structure as needed, such as a circular plate structure without holes, and make the connector 220 or the rotating shaft of the motor 210 fixedly connected to the bottom wall of the barrel body 410, so that the filter container 300 is fixedly connected to the barrel body 410.

[0091] In addition, in other embodiments of the present invention, those skilled in the art may also omit the second annular cavity 4102 as needed, and form the channel inlet 402 at the bottom of the circumferential side wall of the barrel body 410 .

[0092] like Figure 7 , Figure 8 , Fig.10 and Fig.11 As shown, in some embodiments of the present invention, a conical ring segment 411 is disposed on the inner side of the top of the barrel 410 , and the conical ring segment 411 is inclined inward from top to bottom. Moreover, the channel outlet 403 is a plurality of through holes formed on the conical ring segment 411 .

[0093] Those skilled in the art will appreciate that by configuring the inner side of the top of the barrel body 410 to be a conical ring segment 411 that tilts inward from top to bottom, and configuring the channel outlet 403 to be a plurality of through holes formed on the conical ring segment 411, the solution flowing out of the channel outlet 403 can flow downward under the action of its own gravity.

[0094] In addition, in other embodiments of the utility model, those skilled in the art may also omit the setting of the conical ring segment 411 as needed, and set the channel outlet 403 on the inner side of the top of the barrel body 410. Alternatively, those skilled in the art may also set the conical ring segment 411 to be inclined outward from top to bottom as needed.

[0095] like Figure 1 and Figure 3As shown, in some embodiments of the present invention, the centrifugal extractor 001 may further include a drainage member 500 disposed between the filtration container 300 and the pump bucket 400 , and the drainage member 500 is used to drain the solution flowing out of the channel outlet 403 to the filtration container 300 .

[0096] like Figure 12 to Figure 14 As shown, in some embodiments of the present invention, the drainage component 500 defines a drainage cavity 510, and the surrounding wall of the drainage cavity 510 is provided with a first drainage hole 511 opposite to the channel outlet 403 and a second drainage hole 512 opposite to the filter container 300, so that the solution flowing out of the channel outlet 403 enters the filter container 300 through the first drainage hole 511, the drainage cavity 510 and the second drainage hole 512.

[0097] The first drainage hole 511 is formed on the outer circumferential wall of the drainage chamber 510 to correspond to the channel outlet 403 on the pump bucket 400. The second drainage hole 512 is formed on the bottom wall of the drainage chamber 510 to correspond to the liquid permeable hole 302 on the filter container 300.

[0098] like Figure 3 and Fig.14 As shown, the outer wall of the drainage chamber 510 is a conical structure that is compatible with the conical ring segment 411 at the top of the pump bucket 400, so as to ensure that the outer wall of the drainage chamber 510 and the conical ring segment 411 of the pump bucket 400 can fit together, thereby preventing the solution flowing out from the channel outlet 403 from overflowing through the gap between the outer wall of the drainage chamber 510 and the conical ring segment 411 of the pump bucket 400.

[0099] It will be understood by those skilled in the art that by arranging a drainage component 500 between the filter container 300 and the pump bucket 400, and defining the drainage component 500 with a drainage cavity 510, a first drainage hole 511 opposite to the channel outlet 403 and a second drainage hole 512 opposite to the filter container 300 are provided on the peripheral wall of the drainage cavity 510, so that the solution flowing out of the channel outlet 403 can enter the filter container 300 via the first drainage hole 511, the drainage cavity 510 and the second drainage hole 512, thereby defining the flow path of the solution and preventing the solution pumped out of the pump bucket 400 from being thrown everywhere under the action of centrifugal force.

[0100] Return to continue reading Figure 3 The bottom wall of the drainage cavity 510 abuts against the filter container 300 to stop the filter container 300 in the axial direction of the filter container 300, thereby increasing the connection strength of the overall structure and reducing the volume of the overall structure.

[0101] Continue reading Figure 3At least a portion of the drainage member 500 is located between the filter container 300 and the pump bucket 400 in the radial direction of the filter container 300 to reduce the height of the centrifugal extractor 001 in the axial direction.

[0102] As described above, the drainage member 500 can be fixedly connected to the filter container 300 and the pump bucket 400, respectively, so that the driving device 200 transmits power to the pump bucket 400 through the filter container 300 and the drainage member 500. For example, the filter container 300, the drainage member 500 and the pump bucket 400 are sequentially interference fit.

[0103] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the drainage member 500 is cylindrical in shape as a whole, and the filter container 300, the drainage member 500 and the pump bucket 400 are coaxially arranged to improve the stability of the three when rotating.

[0104] Continue reading Figure 3 In the present invention, the drainage member 500, the filter container 300 and the pump bucket 400 define a buffer chamber 520 at least through the drainage member 500. In addition, the buffer chamber 520 is communicated with the filter hole 301 and the channel inlet 402, respectively, so that the buffer chamber 520 receives and buffers the solution thrown out from the filter hole 301, and the solution in the buffer chamber 520 enters the spiral channel 401 through the channel inlet 402.

[0105] Those skilled in the art will appreciate that the buffer chamber 520 is provided between the filter container 300 and the pump bucket 400 to buffer the solution thrown out by the filter container 300 and not yet transported by the pump bucket 400. At the same time, the presence of the buffer chamber 520 also increases the diameter of the pump bucket 400, thereby increasing the centrifugal force on the solution in the pump bucket 400 and improving the pumping capacity of the pump bucket 400 for the solution.

[0106] like Fig.14 As shown, in some embodiments of the present invention, the buffer cavity 520 is defined solely by the drainage member 500 .

[0107] like Figure 12 to Figure 14 As shown, the flow guide member 500 is provided with a cache inlet 521 and a cache outlet 522 on the peripheral wall of the cache cavity 520. The cache inlet 521 is aligned with the filter hole 301 on the filter container 300, and the cache outlet 522 is aligned with the channel inlet 402 on the pump bucket 400, so that the liquid thrown out from the filter container 300 can smoothly enter the spiral channel 401 connected with the channel inlet 402.

[0108] In addition, in other embodiments of the present invention, those skilled in the art may also set the drainage member 500 to any other feasible member as needed, such as a member that only defines the drainage cavity 510, so that the buffer cavity 520 is defined by the drainage member 500, the filter container 300 and the pump bucket 400. Furthermore, the outer peripheral wall and the inner peripheral wall of the drainage cavity 510 may be omitted.

[0109] Of course, in other embodiments of the present invention, those skilled in the art may also omit the provision of the buffer cavity 520 as required.

[0110] like Figures 1 to 3 As shown, in some embodiments of the present invention, the centrifugal extractor 001 may further include a liquid storage container 600 disposed on the body 100 , and the liquid storage container 600 is provided with a solution outlet 601 .

[0111] Furthermore, the pump bucket 400 and the filter container 300 are both arranged in the liquid storage container 600, and a drainage hole 404 is provided at the bottom of the pump bucket 400, so that the solution in the pump bucket 400 can be discharged to the liquid storage container 600 through the drainage hole 404, and then discharged from the centrifugal extractor 001 through the solution outlet 601.

[0112] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the bottom wall of the liquid storage container 600 is hollow to avoid the connector 220. In order to prevent the solution in the liquid storage container 600 from flowing out, an inner rib 620 is also provided in the liquid storage container 600.

[0113] like Figures 1 to 3 As shown, in some embodiments of the present invention, the liquid storage container 600 may be provided with a protrusion 610 protruding radially outward, and the solution outlet 601 is formed on the protrusion 610 to reduce the gap between the area of ​​the liquid storage container 600 other than the protrusion 610 and the first liquid storage container 600 while ensuring that the liquid storage container 600 can receive and discharge the solution.

[0114] like Figure 1 and Figure 3 As shown, the fuselage 100 may be provided with a top installation cavity 101 , an avoidance gap 102 and a bottom installation cavity 103 .

[0115] The top installation cavity 101 is used to install the filter container 300 , the pump bucket 400 , the drainage component 500 and the liquid storage container 600 .

[0116] The avoidance notch 102 is matched with the protrusion 610 on the liquid storage container 600 , so that the protrusion 610 of the liquid storage container 600 is embedded in the avoidance notch 102 to prevent the liquid storage container 600 from rotating relative to the body 100 .

[0117] The bottom mounting cavity 103 is used to mount the motor 210 .

[0118] like Figures 1 to 3 As shown, in some embodiments of the present invention, a knob 110 is provided on the body 100 , and the knob 110 is used to control the rotation speed of the filter container 300 and the pump bucket 400 .

[0119] In addition, those skilled in the art may omit the knob 110 as needed, and control the rotation speed of the filter container 300 and the pump bucket 400 through other buttons or other devices. The other buttons may be physical buttons provided on the centrifugal extractor 001 or virtual buttons displayed on the display screen of the centrifugal extractor 001. The other devices may be remote controllers compatible with the centrifugal extractor 001, or mobile phones, tablets, and other devices connected to the centrifugal extractor 001 for communication.

[0120] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the centrifugal extractor 001 further includes a control valve 700 to control the opening and closing of the solution outlet 601 and / or the drainage hole 404 .

[0121] Furthermore, the control valve 700 is a wax motor installed at the drain hole 404 .

[0122] Of course, those skilled in the art may also set the control valve 700 to any other feasible structure, such as a solenoid valve, as needed. Also, those skilled in the art may also set the control valve 700 at the solution outlet 601 as needed.

[0123] like Fig.10 As shown, in some embodiments of the present invention, the pump bucket 400 is provided with a first avoidance hole 405 at the top of the second annular cavity 4102, and the first avoidance hole 405 is used to avoid the control valve 700, and to reserve sufficient space for the installation of the control valve 700. Exemplarily, the control valve 700 as a wax motor is installed in the first avoidance hole 405 (for example, interference fit with the first avoidance hole 405).

[0124] like Fig.13 and Fig.14 As shown, in some embodiments of the present invention, a second avoidance hole 501 is provided at the bottom of the flow guiding member 500 , and the second avoidance hole 501 is used to avoid the control valve 700 , thereby reserving sufficient space for the installation of the control valve 700 .

[0125] like Figures 1 to 13As shown, in some embodiments of the present invention, the centrifugal extractor 001 may further include a hollow cap 800 , which is detachably mounted on the filter container 300 so as to add liquid to the filter container 300 through the cap 800 .

[0126] like Fig.15 and Fig.16 As shown, in some embodiments of the present invention, the cap 800 includes a hollow large diameter section 810 and a hollow small diameter section 820. The large diameter section 810 is plugged into the filter container 300, specifically, it is adapted to the neck 330 of the filter container 300 to be plugged into the neck 330. The small diameter section 820 is inserted into the filter container 300, so as to guide the liquid into the filter container 300 through the small diameter section 820 while reducing the occupation of the space in the filter container 300 by the small diameter section 820.

[0127] Continue reading Fig.15 and Fig.16 In some embodiments of the present invention, a plurality of liquid sprinkling holes 821 are provided on the peripheral wall of the small diameter section 820, so that the liquid in the small diameter section 820 passes through the plurality of liquid sprinkling holes 821 under the action of centrifugal force and is sprinkled onto the powdered target object 002.

[0128] Furthermore, the plurality of liquid spraying holes 821 are evenly distributed along the circumferential direction and / or axial direction of the small diameter section 820 , so that the liquid in the small diameter section 820 is evenly sprayed toward the powdered target 002 .

[0129] Preferably, the plurality of liquid sprinkling holes 821 are evenly distributed on the entire circumferential side wall of the small diameter section 820 , so that the liquid in the small diameter section 820 is evenly sprinkled toward the powdered target 002 under the action of centrifugal force.

[0130] like Figure 3 As shown, in some embodiments of the present invention, the height of the annular plate portion 320 is less than or equal to the height of the bottom wall of the large diameter section 810 , so that the powdered target 002 at the annular plate portion 320 receives the liquid sprinkled from the liquid sprinkling hole 821 .

[0131] Furthermore, the bottom end of the small diameter section 820 abuts against the inner bottom surface of the filter container 300 to prevent the liquid in the small diameter section 820 from flowing out quickly through the gap between the bottom end of the small diameter section 820 and the inner bottom surface of the filter container 300, thereby preventing the liquid in the small diameter section 820 from being evenly sprinkled onto the powdered target 002.

[0132] In addition, in other embodiments of the present invention, those skilled in the art may also provide a bottom wall for the small diameter section 820 to close the bottom opening thereof as required.

[0133] Furthermore, the diameter of the liquid sprinkling hole 821 is selected from any value between 0.1 mm and 1 mm, so as to avoid the liquid in the small diameter section 820 from being lost too quickly while ensuring that the liquid in the small diameter section 820 can be thrown out under the action of centrifugal force.

[0134] Specifically, the diameter of the liquid sprinkling hole 821 can be any feasible value such as 0.1 mm, 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm, 1 mm, etc.

[0135] Furthermore, the diameter of the small diameter section 820 is selected from any value between 5 mm and 20 mm, so as to avoid the liquid in the small diameter section 820 from being lost too quickly, while at the same time ensuring that the circumferential side wall of the small diameter section 820 has sufficient surface area so that the liquid in the small diameter section 820 can be evenly sprinkled onto the powdered target 002 under the action of centrifugal force.

[0136] Specifically, the diameter of the small diameter section 820 may be any feasible value such as 5 mm, 7 mm, 10 mm, 12 mm, 15 mm, 18 mm, or 20 mm.

[0137] Furthermore, the ratio of the diameter of the small diameter section 820 to the diameter of the large diameter section 810 is selected from any value between 0.2 and 0.8, so that the liquid is buffered by the large diameter section 810 before flowing into the small diameter section 820, thereby preventing too much liquid from being added at a single time, causing the liquid to overflow from the cap 800.

[0138] Specifically, the ratio of the diameter of the small diameter section 820 to the diameter of the large diameter section 810 may be any feasible value such as 0.2, 0.3, 0.33, 0.4, 0.5, 0.6, 0.8, etc.

[0139] Furthermore, the bottom wall of the large diameter section 810 may be inclined downward from the outside to the inside to form a funnel shape, so that all the liquid in the large diameter section 810 can flow into the small diameter section 820 .

[0140] like Fig.15 and Fig.16 As shown, in some embodiments of the present invention, the cap 800 may further include an annular rib 830 disposed at one end of the large diameter section 810 away from the small diameter section 820, and the annular rib 830 abuts against the top of the filter container 300 (specifically, the flange 340 of the filter container 300). At the same time, the annular rib 830 can also increase the structural strength of the cap 800 in the radial direction.

[0141] Refer to the following Figure 3 , Fig.17 and Fig.18 The following is a brief description of the usage and working principle of the centrifugal extractor 001 in some embodiments of the present invention.

[0142] like Fig.17 and Fig.18 As shown, when using the centrifugal extractor 001, the cap 800 is first removed. Then, a sufficient amount of powdered target 002 is put into the filter container 300.

[0143] In order to facilitate the user to put a sufficient amount of powdered target 002 into the filter container 300, a measuring cup or measuring spoon can be configured for the centrifugal extractor 001 to measure the amount of powdered target 002 put into the filter container 300 through the measuring cup or measuring spoon.

[0144] Then, the centrifugal extractor 001 is started (first start), so that the powdery target 002 at the center of the filter container 300 is moved to the circumferential side wall of the filter container 300, and sufficient space is reserved for the cap 800 to prevent the powdery target 002 in the filter container 300 from affecting the installation of the cap 800. Alternatively, the powdery target 002 at the center of the filter container 300 can be swept to the circumferential side wall of the filter container 300 by tools such as chopsticks, spoons, and brushes.

[0145] Then, the centrifugal extractor 001 is started (second start), and liquid (such as water) is injected into the cap 800. The water injection process can be completed by the user, or a water pumping system can be configured for the centrifugal extractor 001 and completed by the water pumping system.

[0146] If the process is completed by the user, a measuring cup can be configured for the centrifugal extractor 001 to measure the volume of the liquid put into the filter container 300 through the measuring cup.

[0147] like Fig.17 and Fig.18 As shown, during this process, the powdered target 002 in the filter container 300 is pressed against the circumferential side wall of the filter container 300 under the action of centrifugal force and is generally in a ring shape. It should be understood that the ring shape of the powdered target 002 is an ideal state, and in actual use, it may not be able to form a ring shape due to the amount of the powdered target 002 and the rotation speed of the filter container 300.

[0148] At the same time, the liquid and solution in the centrifugal extractor 001 are Fig.17 and Fig.18 The flow is shown by the dashed arrow. The details are as follows:

[0149] Under the action of centrifugal force, the liquid in the cap 800 is uniformly sprinkled toward the powdered target 002 through the liquid sprinkling hole 821, and penetrates the powdered target 002 to dissolve some substances in the powdered target 002. Under the action of centrifugal force, the solution containing the powdered target 002 passes through the filter hole 301, is thrown out of the filter container 300, and enters the buffer chamber 520 in the drainage member 500 through the buffer inlet 521.

[0150] The solution in the buffer cavity 520 enters the second annular cavity 4102 of the pump bucket 400 through the buffer outlet 522 and the channel outlet 403 under the action of gravity.

[0151] The solution in the second annular cavity 4102 is thrown into the first annular cavity 4101 where the spiral channel 401 is formed under the action of centrifugal force.

[0152] When the bottom surface of the spiral channel 401 rotates with the pump bucket 400, it provides an upward lift to the solution entering the spiral channel 401. Under the action of the lift, the solution in the first annular cavity 4101 rises to the top of the spiral channel 401 and enters the drainage cavity 510 through the channel inlet 402 and the first drainage hole 511.

[0153] The solution in the drainage cavity 510 is squeezed into the receiving portion 310 of the filtration container 300 again through the second drainage hole 512 and the liquid permeable hole 302 under the action of gravity, and then the above cycle is repeated again.

[0154] Those skilled in the art will appreciate that if the pump bucket 400 has a strong infusion capacity, the solution will fill the drainage chamber 510 and form a certain pressure. Under the action of the pressure, the solution in the drainage chamber 510 will quickly squeeze into the receiving portion 310 of the filter container 300 again through the second drainage hole 512 and the liquid permeable hole 302, and the above cycle will be repeated again.

[0155] When the centrifugal extraction is completed, the control valve 700 is opened, so that the solution in the filter container 300, the pump bucket 400 and the drainage component 500 enters the liquid storage container 600 through the drainage hole 404 under the action of gravity, and finally flows out of the centrifugal extractor 001 from the solution outlet 601.

[0156] Optionally, after the control valve 700 is opened, the motor 210 can continue to rotate, so that the solution in the filter container 300 is separated from the powdered target 002 under the action of centrifugal force, so that the powdered target 002 adsorbs as little solution as possible, thereby improving the extraction efficiency of the centrifugal extractor 001 on the powdered target 002.

[0157] In the present invention, the condition for determining whether the centrifugal extraction is ended can be that the filter container 300, the pump bucket 400 and the drainage member 500 rotate for a set time (for example, 3 minutes, 5 minutes, 8 minutes, 12 minutes, etc., any feasible time), or the concentration of the solution reaches a preset value (for example, 1%, 3%, 5%, 8%, 10%, 20%, 50%, etc.), or it can be determined by the user.

[0158] If the condition for determining whether the centrifugal extraction is finished is that the concentration of the solution reaches a preset value, the centrifugal extractor 001 is further provided with a concentration sensor to detect the concentration of the solution in the filtration container 300 , the pump bucket 400 and the drainage member 500 through the concentration sensor.

[0159] In the above process, the rotation speeds of the filter container 300 and the pump bucket 400 during the first start and the second start can be the same or different. And the rotation speeds of the filter container 300 and the pump bucket 400 can be any value from 200 r / min to 6000 r / min, such as 200 r / min, 500 r / min, 2000 r / min, 3500 r / min, 4800 r / min, 5000 r / min, 6000 r / min, etc.

[0160] In addition, the centrifugal extractor 001 of the present invention can also be used in combination with filter paper. For example, before adding the powdered target object 002 into the filter container 300 , the filter paper is first placed in the filter container 300 .

[0161] In summary, the centrifugal extractor 001 of the utility model can perform cyclic extraction of the powdered target 002 by centrifugation, which not only shortens the extraction time, but also increases the extraction efficiency and the final quality of the solution. The centrifugal extraction method can separate the solution in the filter container 300 from the powdered target 002 under the action of centrifugal force (especially at the end of the extraction), so that the powdered target 002 absorbs less solution, thereby improving the extraction efficiency of the powdered target 002.

[0162] In addition, in other embodiments of the present invention, those skilled in the art may also omit the pump bucket 400 as needed, and set the control valve 700 to control the opening and closing of the solution outlet 601. Thus, the powdered target 002 is fully mixed with the liquid through the rotating filter container 300, and at the end of the extraction, the solution in the filter container 300 is separated from the powdered target 002 under the action of centrifugal force.

[0163] So far, the technical solution of the utility model has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the utility model is not limited to these specific embodiments. Without departing from the technical principle of the utility model, those skilled in the art can split and combine the technical solutions in the above embodiments, and can 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 principle of the utility model will fall within the protection scope of the utility model.

[0164] Finally, it should be noted that in the present invention, the term "communication" means fluid communication, so as to allow fluid (such as air, liquid) to flow between two connected objects. And the "communication" can be to allow the fluid to flow between the two connected objects without leakage, or to allow the fluid to flow between the two connected objects with a little leakage.
