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

[0002] The existing extraction equipment generally extracts coffee and other extraction objects by means of soaking, hot water brewing, cooking and the like, so as to extract target substances in the extraction objects and obtain the final drinking solution.

[0003] The principle of the above-mentioned extraction method is to dissolve and diffuse the target substances in coffee and other extraction objects into the solution by means of molecular diffusion, which not only takes a long time, but also causes the extraction objects to still retain a large amount of target substances after extraction, incomplete extraction, and even affects the taste of the final drinking solution. SUMMARY

[0004] One purpose of the utility model is to solve the problem of poor completeness of extraction of the existing extraction equipment on the extraction objects.

[0005] Another purpose of the utility model is to realize the cyclic extraction of the extraction objects.

[0006] To achieve the above-mentioned purpose, the utility model provides a centrifugal extractor, which comprises:

[0007] a liquid storage container;

[0008] a driving device fixed opposite to the liquid storage container;

[0009] a filter container arranged in the liquid storage container and drivingly connected with the driving device, so that the filter container performs centrifugal extraction on the extraction objects in the filter container and throws the liquid in the filter container into the liquid storage container;

[0010] a screw pump fixed opposite to the liquid storage container and used for conveying the liquid in the liquid storage container into the filter container.

[0011] Optionally, the bottom wall of the liquid storage container is provided with a sink, and the liquid inlet of the screw pump is located in the sink, or a liquid inlet pipe connected with the screw pump extends into the sink.

[0012] Optionally, the inner bottom surface of the liquid storage container is inclined downward toward the direction close to the sink, so that the liquid in the liquid storage container flows to the sink under the action of gravity.

[0013] Optionally, the sink is located on one side of the rotation axis of the filter container; and / or the ratio of the area of the sink to the total area of the bottom wall of the liquid storage container is less than or equal to 1 / 10.

[0014] Optionally, the liquid storage container is provided with a liquid outlet nozzle, an inner end of the liquid outlet nozzle extending to the sink.

[0015] Optionally, the liquid storage container is provided with a plug for plugging an outer end of the liquid outlet nozzle.

[0016] Optionally, the rotation axis of the screw pump is parallel to the rotation axis of the filter container, or the included angle between the two is an acute angle; the liquid inlet of the screw pump is located at the bottom end of the screw pump, and the liquid outlet of the screw pump is located at the top end of the screw pump.

[0017] Optionally, the centrifugal extractor further comprises a liquid outlet pipe fluidly connected to the liquid outlet of the screw pump, an end of the liquid outlet pipe away from the screw pump extending above the filter container.

[0018] Optionally, the centrifugal extractor further comprises a decorative cover mounted to the liquid storage container, the decorative cover being in clearance fit with the filter container, the decorative cover being provided with a through hole for avoiding the liquid outlet pipe to allow the liquid outlet pipe to penetrate through the decorative cover.

[0019] Optionally, the centrifugal extractor further comprises a funnel cover removably mounted to the filter container, the funnel cover being used for receiving the liquid delivered by the screw pump; and / or, the centrifugal extractor further comprises a machine body, the liquid storage container and the driving device are both mounted to the machine body; and / or, the screw pump is a screw pump; and / or, the centrifugal extractor is suitable for extracting coffee.

[0020] Based on the foregoing description, those skilled in the art can understand that, in the technical solutions of the foregoing centrifugal extractor, the filter container driven by the driving device is configured to centrifugally extract the target substance on the material to be extracted placed in the filter container by rotating, and to throw out the target substance extracted from the filter container. During centrifugal extraction, it is easier to throw out the target substance on the material to be extracted from the filter container, so the centrifugal extractor improves the completeness of the extraction of the material to be extracted. The screw pump fixed relative to the liquid storage container is configured to deliver the liquid in the liquid storage container to the filter container, so that the centrifugal extractor can realize the cyclic extraction of the material to be extracted by means of the centrifugal throwing function of the filter container and the liquid delivery function of the screw pump.

[0021] Further, the sink is arranged on the bottom wall of the liquid storage container, so that the liquid storage container can contain sufficient liquid through the sink. The liquid inlet of the screw pump is arranged in the sink, or the liquid inlet pipe connected to the screw pump extends into the sink, so that the screw pump can extract sufficient liquid, avoiding the situation that the screw pump is empty.

[0022] Further, by inclining the inner bottom surface of the liquid storage container downward toward the direction close to the sink, the liquid in the liquid storage container can flow to the sink under the action of gravity, quickly replenishing the sink with liquid for the spiral pump to extract.

[0023] Further, by arranging the sink on one side of the rotation axis of the filter container, and particularly by making the ratio of the area of the sink to the total area of the bottom wall of the liquid storage container less than or equal to 1 / 10, the cross-sectional dimension of the sink is prevented from being too large, which would result in a low liquid depth in the sink, and thus the situation of the spiral pump being empty is avoided.

[0024] Further, by extending the inner side end of the liquid outlet nozzle to the sink, the liquid in the liquid storage container can be discharged as completely as possible through the liquid outlet nozzle.

[0025] Further, by making the rotation axis of the spiral pump parallel to the rotation axis of the filter container, or the included angle between the two being an acute angle, the radial dimension of the centrifugal extractor is prevented from being too large.

[0026] Further, by configuring the centrifugal extractor with a decorative cover, the liquid is prevented from splashing out due to impact on the liquid storage container and other components under the action of centrifugal force, and the spiral pump and other components are hidden, making the centrifugal extractor as a whole more aesthetically pleasing.

In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0048] Further, it should be further noted that in the description of the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances. For example, the terms "mounting", "connection", "connection" and "fixing" can be bolted, screwed, welded, inserted, riveted, fused, clamped or any other feasible connection form without special description.

[0049] As shown in Figures 1 to 5 In some embodiments of the utility model, the centrifugal extractor 001 includes an optional machine body 100, a liquid storage container 200, a driving device 300, a filter container 410 and a screw pump 500.

[0050] Among them, the machine body 100 is defined with a top cavity 101 and a bottom cavity 102, the top cavity 101 is used to arrange the liquid storage container 200, the filter container 410 and the screw pump 500, and the bottom cavity 102 is used to arrange the driving device 300. Of course, under the premise of being able to install the liquid storage container 200, the driving device 300, the filter container 410 and the screw pump 500, those skilled in the art can also set the machine body 100 to other any feasible shape according to the needs, for example, a hollow barrel-shaped member. Alternatively, those skilled in the art can also omit the setting of the machine body 100 according to the needs. That is, under the premise of being able to realize the relative fixation of the liquid storage container 200, the driving device 300 and the filter container 410, those skilled in the art can also omit the machine body 100 according to the needs, or set the machine body 100 and the liquid storage container 200 as a whole.

[0051] Among them, the liquid storage container 200 is used to contain the liquid 002 (as shown in Figure 6 ) added into the centrifugal extractor 001, or the liquid 002 generated in the working process of the centrifugal extractor 001.

[0052] The driving device 300 is fixed relative to the liquid storage container 200, and can be fixedly connected to the machine body 100.

[0053] The filter container 410 is arranged in the liquid storage container 200 and is drivingly connected to the driving device 300, so that the filter container 410 extracts the to-be-extracted material 003 therein by centrifugation, and the extracted liquid 002 is thrown out of the filter container 410 into the liquid storage container 200 under the action of centrifugal force. Figure 6 The filter container 410 is arranged in the liquid storage container 200 and is drivingly connected to the driving device 300, so that the filter container 410 extracts the to-be-extracted material 003 therein by centrifugation, and the extracted liquid 002 is thrown out of the filter container 410 into the liquid storage container 200 under the action of centrifugal force.

[0054] The skilled person can understand that the filter container 410 driven by the driving device 300 can extract the to-be-extracted material 003 placed therein by rotation, and the extracted target substance is thrown out of the filter container 410. During centrifugal extraction, the target substance on the to-be-extracted material 003 is more easily thrown out of the filter container 410, so that the centrifugal extractor 001 of the utility model improves the completeness of the extraction of the to-be-extracted material 003. By arranging the screw pump 500 fixed relative to the liquid storage container 200, the liquid 002 in the liquid storage container 200 is transported into the filter container 410, so that the centrifugal extractor 001 of the utility model can realize the cyclic extraction of the to-be-extracted material 003 by means of the centrifugal throwing function of the filter container 410 on the liquid 002 and the back-transport function of the screw pump 500 on the liquid 002.

[0055] It should be noted that in the utility model, the to-be-extracted material 003 includes coffee powder and / or tea powder. For example, the to-be-extracted material 003 can be coffee powder or tea powder, or a mixture of coffee powder and tea powder.

[0056] Of course, the skilled person can also make the to-be-extracted material 003 include other any feasible powdery substances, such as soybean powder, mung bean powder, cocoa powder, lemon, etc.

[0057] The centrifugal extractor 001 of the utility model generates the liquid 002 containing the target substance during the extraction of the to-be-extracted material 003.

[0058] The target substance can be a substance dissolved in water in the to-be-extracted material 003. The liquid 002 can be a liquid substance of the to-be-extracted material 003 itself, can be water, or can be water containing the target substance. The water can be hot water, normal temperature water or cold water in temperature, and can be pure water, tap water, mineral water or water containing specific substances (such as sugar, milk, essence, etc.) in composition.

[0059] As shown in Figures 1 to 3As shown, in some embodiments of this utility model, a knob 110 may also be provided on the body 100 to adjust the rotation speed of the filter container 410.

[0060] Furthermore, in other embodiments of this utility model, those skilled in the art can omit the knob 110 as needed and control the rotation speed of the filter container 410 using other buttons or other devices. These other buttons can be physical buttons on the centrifugal extractor 001 or virtual buttons displayed on the screen of the centrifugal extractor 001. Other devices can be a remote control compatible with the centrifugal extractor 001, or a mobile phone, tablet, or other device that communicates with the centrifugal extractor 001.

[0061] like Figure 5 As shown, in some embodiments of this utility model, the liquid storage container 200 is placed inside the top cavity 101 of the body 100 and can be detachably connected to the body 100 to facilitate the user to remove the liquid storage container 200 for cleaning. Of course, those skilled in the art can also fix the liquid storage container 200 to the body 100 as needed.

[0062] When the liquid storage container 200 is detachably connected to the machine body 100, both the liquid storage container 200 and the machine body 100 are equipped with anti-rotation structures to prevent the liquid storage container 200 from rotating relative to the machine body 100. For example, Figure 1 and Figure 2 As shown, the liquid storage container 200 has a protruding structure (not marked in the figure) on its peripheral wall, and the body 100 has a slot (not marked in the figure) that matches the protruding structure. The protruding structure is inserted into the slot, thereby fixing the liquid storage container 200 and the body 100 circumferentially θ apart. The side of the liquid storage container 200 away from the protruding structure may also have a hanging ear (not marked in the figure), and the body 100 has a corresponding slot (not marked in the figure). The hanging ear is inserted into the slot to further fix the liquid storage container 200 and the body 100 circumferentially θ apart.

[0063] When the liquid storage container 200 is fixedly connected to the body 100, the two can be fixedly connected together by fastening components, structures or materials such as screws, clips, and adhesives.

[0064] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the bottom wall of the liquid storage container 200 is provided with a clearance hole 201 to avoid the drive device 300. The liquid storage container 200 is also provided with an annular baffle 210 extending from its bottom wall to the top side to prevent the liquid 002 in the liquid storage container 200 from flowing out of the clearance hole 201.

[0065] As Figure 4 and Figure 5 As shown in some embodiments of the present application, the bottom wall of the liquid storage container 200 is provided with a sink 202. The liquid inlet 501 of the screw pump 500 is located in the sink 202, or the liquid inlet pipe 511 connected with the screw pump 500 extends into the sink 202.

[0066] Alternatively, the liquid inlet pipe 511 can be integrally formed with the screw pump 500 according to the needs of those skilled in the art.

[0067] Those skilled in the art can understand that by providing the sink 202 on the bottom wall of the liquid storage container 200, the liquid storage container 200 can accommodate sufficient liquid 002 through the sink 202. By locating the liquid inlet 501 of the screw pump 500 in the sink 202 or extending the liquid inlet pipe 511 connected with the screw pump 500 into the sink 202, the screw pump 500 can extract sufficient liquid 002, avoiding the situation that the screw pump 500 is empty.

[0068] Further, although not shown in the figure, the inner bottom surface of the liquid storage container 200 can be inclined downward toward the direction close to the sink 202 according to the needs of those skilled in the art, so that the liquid 002 in the liquid storage container 200 flows to the sink 202 under the action of gravity, quickly replenishing the sink 202 with liquid 002 for extraction by the screw pump 500.

[0069] As can be seen from Figures 1 to 5 , in some embodiments of the present application, the sink 202 is located on one side of the rotation axis φ of the filter container 410. And / or, the ratio of the area of the sink 202 to the total area of the bottom wall of the liquid storage container 200 is less than or equal to 1 / 10, for example, it can be 1 / 10, 1 / 11, 1 / 13, etc.

[0070] Those skilled in the art can understand that by locating the sink 202 on one side of the rotation axis φ of the filter container 410, especially by making the ratio of the area of the sink 202 to the total area of the bottom wall of the liquid storage container 200 less than or equal to 1 / 10, the cross-sectional size of the sink 202 is avoided to be too large, which leads to the low depth of the liquid 002 in the sink 202, thereby avoiding the situation that the screw pump 500 is empty.

[0071] As Figures 1 to 5 shown, in some embodiments of the present application, the liquid storage container 200 is provided with a liquid outlet nozzle 220, the inner side end of the liquid outlet nozzle 220 extends to the sink 202, so that the liquid 002 in the liquid storage container 200 can be discharged as completely as possible through the liquid outlet nozzle 220.

[0072] With reference to the accompanying drawings Figures 1 to 5 In some embodiments of the present application, the liquid storage container 200 is provided with a plug 230 for plugging the outer end of the liquid outlet nozzle 220, so as to open or plug the liquid outlet nozzle 220 through the plug 230. The plug 230 can be a rubber plug, a threaded plug, a latex plug, a silica gel plug, or any other feasible plug.

[0073] When the plug 230 is opened, the liquid 002 in the liquid storage container 200 can be discharged through the liquid outlet nozzle 220.

[0074] When the plug 230 plugs the liquid outlet nozzle 220, the liquid 002 in the liquid storage container 200 cannot be discharged.

[0075] In addition, in other embodiments of the present application, the skilled in the art can also omit the setting of the liquid outlet nozzle 220 and the plug 230 according to the needs, and make the user pour the liquid 002 in the liquid storage container 200 out of the centrifugal extractor 001.

[0076] As shown in Figure 1 and Figure 2 In some embodiments of the present application, the driving device 300 includes a motor 310 arranged outside the liquid storage container 200 and a driving disc 320 arranged inside the liquid storage container 200, the motor 310 is fixedly connected with the machine body 100 through its casing, the rotating shaft of the motor 310 penetrates through the through hole (not labeled in the figure) on the bottom wall of the top cavity 101 and is fixedly connected with the driving disc 320, the driving disc 320 is fixedly connected with the filter container 410, so that the motor 310 drives the filter container 410 to rotate through the driving disc 320.

[0077] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments of the present application, the centrifugal extractor 001 further includes a base 420 arranged at the bottom side of the filter container 410, the base 420 is coaxially fixed with the filter container 410 or integrally made, so that the filter container 410 is fixedly connected with the driving disc 320 in the circumferential direction θ through the base 420. The fixed connection can be screw connection, riveting, welding, bonding, clamping, welding, or any other feasible connection mode.

[0078] With reference to the accompanying drawings Figure 1 , Figure 2 , Figure 4 and Figure 5In some embodiments of the utility model, base 420 is provided with a plurality of downward extending insertion posts 421, and driving disc 320 is provided with a plurality of upward opening insertion holes 321. Insertion posts 421 are pluggably inserted into insertion holes 321 to splice base 420 and driving disc 320 together. This connection mode facilitates the disassembly of base 420 and filter container 410, and further facilitates the cleaning of base 420 and filter container 410 by the user.

[0079] In addition, in other embodiments of the utility model, the skilled person in the art can also fix base 420 and driving disc 320 together according to the need, and the fixing connection can be any feasible connection mode such as screw connection, riveting, welding, bonding, clamping, welding, etc.

[0080] The skilled person can understand that the arrangement of driving disc 320 and base 420 can improve the structural strength of filter container 410 and prevent filter container 410 from deforming during long-term use.

[0081] Alternatively, the skilled person can also omit the arrangement of base 420 to fix filter container 410 directly with driving disc 320 according to the need. The skilled person can also omit the arrangement of driving disc 320 and fix filter container 410 directly with the rotating shaft of motor 310 according to the need.

[0082] As shown in Figure 2 , Figure 4 and Figure 5 , in some embodiments of the utility model, base 420 is provided with an annular groove 422 facing downward, and annular baffle 210 in filter container 410 is embedded in annular groove 422 to prevent liquid 002 in filter container 410 from leaking out of avoiding hole 201.

[0083] As shown in Figure 4 and Figure 5 , in some embodiments of the utility model, the rotating axis φ of screw pump 500 is parallel to the rotating axis φ of filter container 410, and the liquid inlet 501 of screw pump 500 is located at the bottom end of screw pump 500, and the liquid outlet 502 of screw pump 500 is located at the top end of screw pump 500.

[0084] In addition, in other embodiments of the utility model, the skilled person in the art can also make the included angle between the rotating axis φ of screw pump 500 and the rotating axis φ of filter container 410 be an acute angle according to the need.

[0085] The person skilled in the art can understand that, by making the rotation axis φ of the screw pump 500 parallel to the rotation axis φ of the filtering container 410, or the included angle between the two being an acute angle, the radial r dimension of the centrifugal extractor 001 is prevented from being too large.

[0086] In addition, in other embodiments of the present application, the person skilled in the art can also select a screw pump 500 with the liquid inlet 501 not located at the bottom end and / or the liquid outlet 502 not located at the top end according to the needs. For example, the liquid inlet 501 is located at the bottom end, and the liquid outlet 502 is located at the top but not at the top end of the screw pump 500.

In addition, the person skilled in the art can also arrange the liquid inlet pipe 511 according to the needs, and thus the liquid inlet 501 of the screw pump 500 is formed on the pump shell 510.

[0088] Further, although not shown in the drawings, in some embodiments of the present application, the screw pump 500 further comprises or is connected with a driving motor, which is drivingly connected with the screw body 520 to drive the screw body 520 to rotate, thereby realizing the delivery of the liquid 002.

[0098] The working principle and use method of the centrifugal extractor 001 in some embodiments of the present application will be briefly described below. Figures 4 to 6

[0099] First, the to-be-extracted material 003 is added into the filter container 410. Then, the motor 310 is started for a period of time (for example, 5S, 10S, 30S, etc.) to make the to-be-extracted material 003 adhere to the circumferential wall of the filter container 410.

[0100] Then, the funnel cover 700 is inserted into the filter container 410, and sufficient water is added into the funnel cover 700.

[0101] Finally, the reflux cover is installed on the filter container 410, and the centrifugal extractor 001 is started to make the motor 310 rotate again to extract the to-be-extracted material 003. At the same time, the screw pump 500 is started, or is started after a period of time (for example, 5S, 10S, 30S, etc.) to ensure that the screw pump 500 can suck the liquid 002 when it is started.

[0102] As shown in Figure 6 the process of extracting the to-be-extracted material 003, the liquid 002 (as shown by the arrow in the figure) in the funnel cover 700 is thrown to the to-be-extracted material 003 under the action of centrifugal force, and then passes through the to-be-extracted material 003 and is thrown out of the filter container 410 into the liquid storage container 200. At the same time, the screw pump 500 will transport the liquid in the liquid storage container 200 into the funnel cover 700, so that the liquid 002 enters the next cycle.

[0103] In the present application, whether the centrifugal extractor 001 completes the extraction of the to-be-extracted material 003 can be determined by counting the running time of the motor 310, or can be determined by determining whether the solubility of the liquid 002 in the liquid storage container 200 reaches the value set by the user.

[0104] Based on the foregoing description, those skilled in the art can understand that the centrifugal extractor 001 in some embodiments of the present application not only has a high extraction rate, but also has a cyclic extraction function.

[0105] ​Thus far, the technical solutions of the present application have been described in combination with the foregoing embodiments, but it will be readily understood by those skilled in the art that the protection scope of the present application is not limited to these specific embodiments.

[0106] Finally, it needs to be noted that in the present application, the term "communication" means fluid communication to allow fluid (for example, air, liquid 002) to flow between two things in communication with each other. And the "communication" can be fluid leakage-free flow between two things in communication with each other, or can be fluid leakage flow between two things in communication with each other.
