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 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] However, the long soaking of powdered objects such as coffee, especially coffee, not only increases the waiting time of users, but also may reduce the taste and freshness of the solution due to long-term contact with air. Utility Model Content

[0005] One purpose of the utility model is to solve the problem of long soaking time when cold-brewing powdered target objects such as coffee by existing extraction equipment.

[0006] To achieve the above object, the utility model provides a centrifugal extractor, comprising:

[0007] body;

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

[0009] A filter container is connected to the driving device and driven to rotate by the driving device, so that the powdered target put into the filter container adheres to the circumferential side wall of the filter container under the action of centrifugal force, and the liquid entering the filter container passes through the powdered target under the action of centrifugal force to form a solution and is thrown out of the filter container;

[0010] A liquid storage container is arranged outside the filtering container to receive the solution thrown out from the filtering container;

[0011] At least one spiral pipeline is arranged on the outside of the filtering container and is drivingly connected to the driving device so as to be driven to rotate by the driving device, thereby pumping the solution in the liquid storage container back into the filtering container.

[0012] Optionally, an annular cavity is defined between the filter container and the liquid storage container, and at least a portion of the spiral pipeline is arranged in the annular cavity.

[0013] Optionally, the bottom end of the spiral pipeline is located at the bottom of the annular cavity, and the top end of the spiral pipeline is located at the top side of the filter container, so that the rotating spiral pipeline pumps the solution in the liquid storage container to the top of the filter container; and / or, the bottom end of the spiral pipeline cooperates with the gap between the stationary side wall of the annular cavity and the fuselage, so as to improve the liquid absorption capacity of the spiral pipeline while ensuring that the spiral pipeline can rotate.

[0014] Optionally, the spiral pipeline is a pipeline with a cross section of a circular ring, an elliptical ring or a rectangular ring.

[0015] Optionally, the number of turns of the spiral pipeline is greater than or equal to 0.5.

[0016] Optionally, the number of turns of the spiral pipeline is selected from any value between 0.5 and 3.

[0017] Optionally, the centrifugal extractor further comprises a fixing structure fixedly connected to the driving device and / or the filtering container, wherein the fixing structure is fixedly connected to the spiral pipeline to improve the stability of the spiral pipeline during rotation.

[0018] Optionally, the centrifugal extractor further comprises a hollow cap detachably mounted on the filtration container, so as to add liquid into the filtration container through the cap.

[0019] Optionally, the top end of the spiral pipeline is located on the top side of the cap so that the cap receives the solution refluxed from the spiral pipeline; and / or, a plurality of liquid sprinkling holes are provided on the circumferential side wall of the cap so that the liquid and solution in the cap pass through the plurality of liquid sprinkling holes under the action of centrifugal force and are sprinkled onto the powdered target object.

[0020] Optionally, the liquid storage container is provided with a liquid outlet, and the centrifugal extractor further comprises a valve for blocking or controlling the opening and closing of the liquid outlet; and / or, the driving device comprises a motor; and / or, the powdered target comprises coffee powder and / or tea powder.

[0021] Based on the foregoing description, those skilled in the art can understand that in the aforementioned technical solution of the utility model, the rotating filter container can make the powdered target inside it adhere to its circumferential side wall under the action of centrifugal force, thereby increasing the surface area of ​​the powdered target in the vertical direction, which is conducive to the liquid to evenly penetrate the powdered target and accelerate the extraction process. Moreover, the filter container can also make the liquid entering it quickly pass through the powdered target under the action of centrifugal force to form a solution and be thrown out from the filter container into the liquid storage container. Then, the solution in the liquid storage container is pumped back into the filter container through the rotating spiral pipeline, and this reciprocating cycle is realized to achieve the cyclic extraction of the powdered target, improve the extraction efficiency and the final quality of the solution, and shorten the soaking time of the powdered target.

[0022] Furthermore, by arranging at least a portion of the spiral pipeline in the annular cavity between the filter container and the liquid storage container, the centrifugal extractor is more compact and smaller in size. At the same time, at least a portion of the spiral pipeline can be hidden inside the centrifugal extractor, making the centrifugal extractor look more concise and beautiful as a whole.

[0023] Furthermore, by positioning the bottom end of the spiral pipe at the bottom of the annular cavity, it is ensured that the rotating spiral pipe can quickly extract the solution in the annular cavity, especially when there is less solution in the annular cavity (for example, when the liquid storage container just starts to receive the solution thrown out from the filter container). By matching the bottom end of the spiral pipe with the clearance of the annular cavity relative to the stationary side wall of the body, while ensuring that the spiral pipe can rotate, the amount of solution lost from the gap between the bottom end of the spiral pipe and the stationary side wall of the annular cavity is reduced.

[0024] Furthermore, the spiral pipeline is fixed by a fixing structure fixedly connected to the driving device and / or the filter container, thereby improving the stability of the spiral pipeline during rotation and preventing the spiral pipeline from shaking or being seriously eccentric during rotation.

[0025] Furthermore, by positioning the top end of the spiral pipe on the top side of the cap, the cap can receive the solution refluxed from the spiral pipe and guide the solution into the filter container. By providing a plurality of liquid sprinkling holes on the circumferential side wall of the cap, the liquid and solution in the cap can pass through the plurality of liquid sprinkling holes under the action of centrifugal force and be sprinkled onto the powdered target, thereby enabling the powdered target in each area of ​​the filter container to receive the liquid and solution.

[0026] Furthermore, by configuring a liquid outlet hole for the liquid storage container, the solution extracted by the centrifugal extractor can be discharged through the liquid outlet hole. By configuring a valve for blocking or controlling the opening and closing of the liquid outlet hole, the solution is prevented from flowing out of the liquid outlet hole during the process of extracting the powdered target by the centrifugal extractor.

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.

[0056] like Figures 1 to 3 As shown, in the first embodiment of the present invention, the centrifugal extractor 001 innovatively uses the centrifugal extraction technology and includes a body 100 , a driving device 200 , a filtering container 300 , a liquid storage container 400 and at least one spiral pipeline 500 .

[0057] The driving device 200 is installed on the body 100 .

[0058] 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 Figure 8 and Fig. 9 As shown in the figure, the powdered target 002 is 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 passes through the powdered target 002 under the action of centrifugal force to form a solution and is thrown out of the filter container 300.

[0059] The liquid storage container 400 is disposed outside the filter container 300 to receive the solution ejected from the filter container 300 .

[0060] The spiral pipeline 500 is disposed outside the filter container 300 and is drivingly connected to the driving device 200 so as to be driven to rotate by the driving device 200 , thereby pumping the solution in the liquid storage container 400 back into the filter container 300 .

[0061] It is understood by those skilled in the art that in the first embodiment of the present invention, the rotating filter container 300 can make the powdered target 002 inside it adhere to its circumferential side wall under the action of centrifugal force, thereby increasing the surface area of ​​the powdered target 002 in the vertical direction, which is conducive to the uniform penetration of the liquid into the powdered target 002 and accelerating the extraction process. Moreover, the filter container 300 can also make the liquid entering it quickly pass through the powdered target 002 under the action of centrifugal force to form a solution and be thrown out from the filter container 300 into the liquid storage container 400. Then, the solution in the liquid storage container 400 is pumped back into the filter container 300 through the rotating spiral pipeline 500, and the reciprocating cycle is realized to realize the cyclic extraction of the powdered target 002, improve the extraction efficiency and the final quality of the solution, and shorten the soaking time of the powdered target 002.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] like Figure 1 and Figure 3 As shown, in the first embodiment of the utility model, 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, so that the motor 210 drives the filter container 300 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 is also provided with a plurality of connection holes, so that the filter container 300 can be fixed to the connector 220 by means of bolts matching the connection holes of the two.

[0069] Furthermore, although not shown in the figures, in the first embodiment of the utility model, those skilled in the art can also, as needed, fix the spiral piping 500 with the connector 220, or fix the spiral piping 500 with the filter container 300, or fix the spiral piping 500 with the connector 220 and the filter container 300 at the same time.

[0070] Exemplarily, the connector 220 and the filter container 300 are respectively interference fit with the spiral pipe 500, so that they are fixed together by the friction between them. Alternatively, at least one of the connector 220 and the filter container 300 is fixed together with the spiral pipe 500 by any feasible connection method such as welding, clamping, screw connection, etc. For example, the spiral pipe 500 is clamped by a pipe clamp, and then the pipe clamp is fixed to the connector 220 or the filter container 300 by welding, clamping or screw connection.

[0071] In addition, in other embodiments of the present invention, those skilled in the art may also configure the drive device 200 to any other feasible form as needed, such as making the drive device 200 include only the motor 210, and making the rotating shaft of the motor 210 directly fixedly connected to the filter container 300.

[0072] like Figure 3 As shown, the filtration container 300 is located between the top and bottom ends of the spiral pipe 500 in its axial direction, so that the solution thrown out from the filtration container 300 can flow to the bottom end of the spiral pipe 500 and the filtration container 300 receives the solution flowing out from the top end of the spiral pipe 500.

[0073] 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 .

[0074] like Figure 1 , Figure 3 and Figure 4 As shown, in the first embodiment of the present utility model, 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.

[0075] 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.

[0076] like Figure 4 As shown, in the first embodiment of the utility model, the filter container 300 includes a receiving portion 310 provided with a first through 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.

[0077] 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.

[0078] Continue reading Figure 4 In the first embodiment of the utility model, a plurality of second through holes 302 may be provided on the annular plate portion 320, so that when the powdered target 002 in the filter container 300 receives a lot of liquid or solution and cannot be discharged from the first through hole 301 in time, part of the liquid or solution is discharged from the second through hole 302. That is, the second through holes 302 on the annular plate portion 320 can play a role in regulating the flow rate of the solution.

[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 Figure 4 In the first embodiment 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 Figure 1 , Figure 3 and Figure 5 As shown, in the first embodiment of the present utility model, the liquid storage container 400 is provided with a liquid outlet 401. The liquid storage container 400 can be detachably connected to the body 100, can be fixedly connected to the body 100, or can be integrally made with the body 100.

[0083] Furthermore, the filter container 300 is arranged in the liquid storage container 400 , so that the liquid storage container 400 receives the solution thrown out from the filter container 300 , and discharges the received solution through the liquid outlet 401 .

[0084] like Figures 1 to 3 As shown, in the first embodiment of the present utility model, the centrifugal extractor 001 may further include a valve 700 for blocking or controlling the opening and closing of the liquid outlet 401. When the centrifugal extractor 001 extracts the powdered target 002, the valve 700 closes the liquid outlet 401; when the centrifugal extractor 001 needs to discharge the solution, the valve 700 opens the liquid outlet 401.

[0085] Among them, the valve 700 can be Figures 1 to 3 The plug or manual switch shown (similar to a faucet) is manually operated by the user to open and close the liquid outlet 401. The valve 700 can be an electric valve so that the centrifugal extractor 001 automatically controls the opening and closing of the valve 700.

[0086] like Figures 1 to 3As shown, in the first embodiment of the utility model, the liquid storage container 400 can be provided with a protrusion 410 protruding radially outward, and the liquid outlet hole 401 is formed on the protrusion 410 to reduce the gap between the liquid storage container 400 and the area other than the protrusion 410 while ensuring that the liquid storage container 400 can receive and discharge the solution.

[0087] like Figure 1 and Figure 3 As shown, in the first embodiment of the present utility model, the bottom wall of the liquid storage container 400 is hollow to avoid the connector 220. In order to prevent the solution in the liquid storage container 400 from flowing out, an inner rib 420 is also provided in the liquid storage container 400.

[0088] like Figure 3 As shown, in the first embodiment of the utility model, a downwardly opening annular groove 221 may be provided on the connector 220, so that the inner rib 420 of the liquid storage container 400 is embedded in the annular groove 221 and cooperates with the clearance of the peripheral wall of the annular groove 221, so as to ensure that the inner rib 420 can rotate and be hidden by the connector 220, which is more beautiful, while preventing the solution in the liquid storage container 400 from flowing out.

[0089] 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 .

[0090] The top installation cavity 101 is used to install the filter container 300 .

[0091] The avoidance notch 102 is matched with the protrusion 410 on the liquid storage container 400 , so that the protrusion 410 of the liquid storage container 400 is embedded in the avoidance notch 102 to prevent the liquid storage container 400 from rotating relative to the body 100 .

[0092] The bottom mounting cavity 103 is used to mount the motor 210 .

[0093] like Figures 1 to 3 As shown, in the first embodiment of the present utility model, 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 .

[0094] In addition, those skilled in the art may omit the knob 110 as needed, and control the rotation speed of the filter container 300 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.

[0095] like Figure 3 As shown, in the first embodiment of the utility model, an annular cavity 010 is defined between the filter container 300 and the liquid storage container 400, and at least a portion of the spiral pipe 500 is arranged in the annular cavity 010, so that the centrifugal extractor 001 is more compact and smaller in size as a whole. At the same time, at least a portion of the spiral pipe 500 can be hidden inside the centrifugal extractor 001, making the centrifugal extractor 001 look more concise and beautiful as a whole.

[0096] Continue reading Figure 3 In the first embodiment of the utility model, the bottom end of the spiral pipeline 500 is located at the bottom of the annular cavity 010, and the top end of the spiral pipeline 500 is located on the top side of the filter container 300, so that the rotating spiral pipeline 500 pumps the solution in the liquid storage container 400 to the top of the filter container 300.

[0097] It will be understood by those skilled in the art that by positioning the bottom end of the spiral pipe 500 at the bottom of the annular cavity 010, it is ensured that the rotating spiral pipe 500 can quickly draw the solution into the annular cavity 010, especially when there is less solution in the annular cavity 010 (for example, when the liquid storage container 400 begins to receive the solution thrown out from the filter container 300).

[0098] Furthermore, the bottom end of the spiral pipe 500 cooperates with the clearance of the stationary side wall of the annular cavity 010 relative to the body 100 to improve the liquid absorption capacity of the spiral pipe 500 while ensuring that the spiral pipe 500 can rotate.

[0099] It will be understood by those skilled in the art that by matching the bottom end of the spiral pipe 500 with the clearance of the stationary side wall of the annular cavity 010 relative to the body 100, while ensuring that the spiral pipe 500 can rotate, the amount of solution lost from the gap between the bottom end of the spiral pipe 500 and the stationary side wall of the annular cavity 010 (specifically the liquid storage container 40) is reduced.

[0100] Furthermore, in the first embodiment of the present invention, the number of turns of the spiral pipe 500 is greater than or equal to 0.5, so as to ensure the pumping capacity of the spiral pipe 500 for the solution.

[0101] Furthermore, the number of turns of the spiral pipe 500 is selected from any value between 0.5 and 3. For example, the number of turns of the spiral pipe 500 can be 0.5, 0.8, 1, 1.5, 2, 2.5, 3, and the like.

[0102] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, in the first embodiment of the present invention, the centrifugal extractor 001 may further include a hollow cap 600 , which is detachably mounted on the filter container 300 so as to add liquid into the filter container 300 through the cap 600 .

[0103] like Figure 3 As shown, in the first embodiment of the present invention, the top end of the spiral tube 500 is located on the top side of the cap 600 , so that the cap 600 receives the solution refluxed from the spiral tube 500 .

[0104] like Figure 6 and Figure 7 As shown, in the first embodiment of the present invention, a plurality of liquid sprinkling holes 621 are provided on the circumferential side wall of the cap 600 , so that the liquid and solution in the cap 600 pass through the plurality of liquid sprinkling holes 621 under the action of centrifugal force and are sprinkled onto the powdered target 002 .

[0105] Specifically, the cap 600 includes a hollow large diameter section 610 and a hollow small diameter section 620. The large diameter section 610 is plugged into the filter container 300, specifically adapted to the neck 330 of the filter container 300 to be plugged into the neck 330. The small diameter section 620 is inserted into the filter container 300 to guide the liquid into the filter container 300 through the small diameter section 620 while reducing the space occupied by the small diameter section 620 in the filter container 300.

[0106] Continue reading Figure 6 and Figure 7 In the first embodiment of the present invention, the liquid sprinkling holes 621 are arranged on the peripheral wall of the small diameter section 620, so that the liquid in the small diameter section 620 passes through the plurality of liquid sprinkling holes 621 under the action of centrifugal force and is sprinkled onto the powdered target 002.

[0107] Furthermore, the plurality of liquid spraying holes 621 are evenly distributed along the circumferential direction and / or axial direction of the small diameter section 620 , so that the liquid in the small diameter section 620 is evenly sprayed toward the powdered target 002 .

[0108] Preferably, the plurality of liquid sprinkling holes 621 are evenly distributed on the entire circumferential side wall of the small diameter section 620 , so that the liquid in the small diameter section 620 is evenly sprinkled toward the powdered target 002 under the action of centrifugal force.

[0109] like Figure 3 As shown, in the first embodiment 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 610 , so that the powdered target 002 at the annular plate portion 320 receives the liquid sprinkled from the liquid sprinkling hole 621 .

[0110] Furthermore, the bottom end of the small diameter section 620 can abut against the inner bottom surface of the filter container 300 to prevent the liquid in the small diameter section 620 from flowing out quickly through the gap between the bottom end of the small diameter section 620 and the inner bottom surface of the filter container 300, thereby preventing the liquid in the small diameter section 620 from being evenly sprinkled onto the powdered target 002.

[0111] 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 620 to close the bottom opening thereof as required.

[0112] Furthermore, the diameter of the liquid sprinkling hole 621 is selected from any value between 0.1 mm and 1 mm, so as to avoid excessive loss of liquid in the small diameter section 620 while ensuring that the liquid in the small diameter section 620 can be thrown out under the action of centrifugal force.

[0113] Specifically, the diameter of the liquid sprinkling hole 621 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.

[0114] Furthermore, the diameter of the small diameter section 620 is selected from any value between 5 mm and 20 mm, so as to avoid the liquid in the small diameter section 620 from being lost too quickly, while at the same time making the circumferential side wall of the small diameter section 620 have sufficient surface area so that the liquid in the small diameter section 620 can be evenly sprinkled onto the powdered target 002 under the action of centrifugal force.

[0115] Specifically, the diameter of the small diameter section 620 may be any feasible value such as 5 mm, 7 mm, 10 mm, 12 mm, 15 mm, 18 mm, or 20 mm.

[0116] Furthermore, the ratio of the diameter of the small diameter section 620 to the diameter of the large diameter section 610 is selected from any value between 0.2 and 0.8, so that the liquid is buffered by the large diameter section 610 before flowing into the small diameter section 620, thereby preventing too much liquid from being added at a single time, causing the liquid to overflow from the cap 600.

[0117] Specifically, the ratio of the diameter of the small diameter section 620 to the diameter of the large diameter section 610 may be any feasible value such as 0.2, 0.3, 0.33, 0.4, 0.5, 0.6, 0.8, etc.

[0118] Furthermore, the bottom wall of the large diameter section 610 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 610 can flow into the small diameter section 620 .

[0119] like Figure 6 and Figure 7As shown, in the first embodiment of the present invention, the cap 600 may further include an annular rib 630 disposed at one end of the large diameter section 610 away from the small diameter section 620, and the annular rib 630 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 630 can also increase the structural strength of the cap 600 in the radial direction.

[0120] Refer to the following Figure 3 , Figure 8 and Fig. 9 The following is a brief description of the usage and working principle of the centrifugal extractor 001 in the first embodiment of the present invention.

[0121] like Figure 3 , Figure 8 and Fig. 9 As shown, when using the centrifugal extractor 001, the cap 600 is first removed. Then, a sufficient amount of powdered target 002 is put into the filter container 300.

[0122] 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.

[0123] Then, the centrifugal extractor 001 is started (first start), so that the powdered 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 600 to prevent the powdered target 002 in the filter container 300 from affecting the installation of the cap 600. Alternatively, the powdered 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.

[0124] Then, the centrifugal extractor 001 is started (second start), and liquid (such as water) is injected into the cap 600. The water injection process can be completed by the user, or a pumping system can be configured for the centrifugal extractor 001 and completed by the pumping system.

[0125] 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.

[0126] like Figure 8 and Fig. 9As 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.

[0127] At the same time, the liquid and solution in the centrifugal extractor 001 are Fig. 9 The flow is shown by the dashed arrow. The details are as follows:

[0128] Under the action of centrifugal force, the liquid in the cap 600 is evenly sprinkled toward the powdered target 002 through the liquid sprinkling hole 621, 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 first through hole 301, is thrown out of the filter container 300, and enters the liquid storage container 400. Specifically, it enters the annular cavity 010 between the liquid storage container 400 and the filter container 300.

[0129] The spiral pipe 500 rotating in the annular cavity 010 forms a pumping device, so that the spiral pipe 500 absorbs the solution in the annular cavity 010, and the spiral pipe 500 provides an upward lift to the solution therein. Under the action of the lift, the solution is pumped to the top of the cap 600 through the spiral pipe 500 and flows into the cap 600.

[0130] The liquid received by the cap 600 is evenly sprinkled toward the powdered target 002 through the liquid sprinkling hole 621 again under the action of centrifugal force, and the cycle is repeated until the extraction is completed.

[0131] When the centrifugal extraction is completed, the valve 700 is opened to allow the solution in the liquid storage container 400 to be discharged through the liquid outlet 401 .

[0132] In the present invention, the condition for determining whether the centrifugal extraction is ended can be that the filter container 300 is rotated for a set time (for example, 3 minutes, 5 minutes, 8 minutes, 12 minutes, or 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.

[0133] If the condition for determining whether the centrifugal extraction is finished is when the concentration of the solution reaches a preset value, the centrifugal extractor 001 is further provided with a concentration sensor (not shown in the figure) to detect the concentration of the solution in the liquid storage container 400 through the concentration sensor. The concentration sensor can be arranged at the inner bottom of the liquid storage container 400.

[0134] In the above process, the rotation speeds of the filter container 300 and the spiral pipe 500 during the first start-up and the second start-up may be the same or different. The rotation speeds of the filter container 300 and the spiral pipe 500 may be any value between 200 r / min and 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.

[0135] Furthermore, those skilled in the art may also, as needed, cause the filter container 300 and the spiral pipe 500 to continue rotating in the opposite direction for a period of time (e.g., 30S, 45S, 60S, 2min, etc.) after the valve 700 is opened, so as to discharge the solution in the spiral pipe 500 and minimize the amount of solution adsorbed by the powdered target object 002 in the filter container 300.

[0136] 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 .

[0137] It should be noted that the spiral pipeline 500 of the present invention is not limited to Figures 1 to 3 The pipeline with a circular cross section shown in the figure can also be any other feasible form, for example, it can also be an elliptical ring, a rectangular ring, a strip ring, etc. Fig.10 and Fig.11 Another form of spiral pipeline 500 of the present invention is described by way of example.

[0138] like Fig.10 As shown, in the second embodiment shown therein, Figures 1 to 3 The difference between the spiral pipeline 500 shown in FIG. 5 is that a rectangular liquid pipetting head 510 is provided at the bottom end of the spiral pipeline 500 to adapt to the bottom space of the annular cavity 010 .

[0139] Those skilled in the art will appreciate that the arrangement of the pipette head 510 enables a clearance fit between the bottom end of the spiral pipe 500 and the stationary side wall of the annular cavity 010 relative to the body 100 (specifically, the liquid storage container 400), thereby ensuring that the spiral pipe 500 can rotate while reducing the amount of solution lost from the gap between the bottom end of the spiral pipe 500 and the stationary side wall of the annular cavity 010, thereby improving the liquid pipette capacity of the spiral pipe 500.

[0140] like Fig.11 As shown, in the third embodiment shown therein, the spiral pipeline 500 is a rectangular pipeline.

[0141] Further, in Fig.12 and Fig.13 In the fourth embodiment shown, the centrifugal extractor 001 may further include a fixing structure 800 fixedly connected to the driving device 200 and / or the filtering container 300, and the fixing structure 800 is fixedly connected to the spiral pipeline 500 to improve the stability of the spiral pipeline 500 during rotation.

[0142] Optionally, Fig.12 and Fig.13 The fixing structure 800 shown can be fixedly connected to the filter container 300 and / or the connector 220 by any feasible connection method such as interference fit, screw connection, welding, etc.

[0143] from Fig.12 and Fig.13 As can be seen in the figure, the fixing structure 800 is a cylindrical structure as a whole, and the circumferential side wall is hollowed out to avoid the solution thrown out from the filtering container 300.

[0144] Furthermore, a plurality of buckles 810 are provided on the outer side of the fixing structure 800 , so as to be snapped together with the spiral pipeline 500 through the buckles 810 , thereby fixing the spiral pipeline 500 and the fixing structure 800 together.

[0145] In summary, the centrifugal extractor 001 of the present invention realizes the cyclic extraction of the powdered target 002 through the centrifugal extraction technology, thereby improving the extraction efficiency and the final quality of the solution.

[0146] 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.

[0147] 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.
