Description

Technical Field

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

[0002] In the traditional food and beverage industry, extraction is a common process used to extract liquid components or flavor compounds from solid substances. For example, in coffee and tea production, extraction is a crucial step in extracting flavor compounds from coffee beans and tea leaves. Traditional extraction methods, such as immersion and pressure methods, typically rely on thermodynamic principles, extracting flavor components through the contact of hot water with coffee grounds or tea leaves. While effective, these methods have limitations in terms of efficiency, uniformity, and controllability. Utility Model Content

[0003] One objective of this invention is to solve the problem of low extraction efficiency in existing extraction equipment.

[0004] To achieve the above objectives, this utility model provides a centrifugal extractor, comprising:

[0005] liquid storage container;

[0006] The driving device is fixed relative to the liquid storage container;

[0007] A filter container is disposed inside the liquid storage container and driven and connected to the driving device to extract the extractant placed in the filter container by centrifugation;

[0008] A hot water tank for providing hot water to the filter container;

[0009] A heating device for heating the water in the hot water tank.

[0010] Optionally, the heating device is an electric heating wire disposed on the outside or inside of the hot water tank.

[0011] Optionally, the heating device is an electromagnetic coil disposed on the outside of the hot water tank; the hot water tank is provided with a metal structure to be heated by the electromagnetic coil.

[0012] Optionally, the centrifugal extractor further includes a hot water valve fluidly connected to the hot water tank, the hot water valve being used to control whether the hot water in the hot water tank flows to the filter container.

[0013] Optionally, the centrifugal extractor further includes an ambient temperature water tank for supplying water to the hot water tank.

[0014] Optionally, the centrifugal extractor further includes a hot water pump connected in series between the hot water tank and the ambient temperature water tank, so as to transport water from the ambient temperature water tank to the hot water tank via the hot water pump.

[0015] Optionally, the centrifugal extractor further includes an integral annular barrel-shaped spiral pump, which is disposed on the outer side of the filter container in the radial direction and is drivenly connected to the drive device so that the spiral pump can transport the liquid thrown out of the filter container into the storage container back into the filter container.

[0016] Optionally, the centrifugal extractor further includes an annular connecting member disposed between the screw pump and the filter container, the connecting member being used to guide the liquid returned by the screw pump into the filter container.

[0017] Optionally, the filter container includes a large-diameter bottom section and a small-diameter top section. The large-diameter bottom section is used to accommodate the extractant. The inner sidewall of the top of the connecting member abuts against the outer peripheral surface of the small-diameter top section. The bottom wall of the top of the connecting member abuts against the large-diameter bottom section. The outer peripheral wall of the top of the connecting member abuts against the inner peripheral surface of the spiral pump.

[0018] Optionally, the centrifugal extractor is configured such that the heating device can heat the liquid inside the top of the connecting member.

[0019] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by configuring a filter container, a hot water tank, and a heating device driven by a driving device, the centrifugal extractor can produce hot water and deliver the produced hot water to the filter container, thereby enabling the filter container to centrifuge and extract the substance to be extracted placed inside by rotation. Centrifugation makes it easier for hot water to permeate the substance to be extracted, accelerating the dissolution of the target substance within the substance, thus improving the extraction efficiency compared to existing technologies.

[0020] Furthermore, by configuring a screw pump, the liquid thrown out of the filter container into the storage container is transported back into the filter container, realizing the cyclic extraction of the extractant in the centrifugal extractor and further improving the extraction efficiency.

[0057] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0058] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the corresponding device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0059] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[0060] like Figures 1 to 4 As shown, in some embodiments of this utility model, the centrifugal extractor 001 includes a body 100, a liquid storage container 200, a drive device 300, a filter container 400, a spiral pump 510, a connecting component 600, a pressure cap 700, and a water supply device 800.

[0061] The body 100 includes a top cavity 101 and a bottom cavity 102. The top cavity 101 is used to house the liquid storage container 200, the filter container 400, the screw pump 510, the connecting member 600, the pressure cap 700, and the water supply device 800. The bottom cavity 102 is used to house the drive device 300. Of course, provided that the liquid storage container 200, the drive device 300, the filter container 400, the screw pump 510, the connecting member 600, the pressure cap 700, and the water supply device 800 can be installed, those skilled in the art can also set the body 100 to any other feasible shape as needed, such as a hollow barrel-shaped component.

[0062] Furthermore, in other embodiments of this utility model, those skilled in the art can omit the body 100 as needed. That is, provided that the liquid storage container 200, the drive device 300, and the filter container 400 can be relatively fixed, those skilled in the art can omit the body 100 as needed, or set the body 100 and the liquid storage container 200 as a whole.

[0063] The liquid storage container 200 is used to contain the liquid 002 (such as liquid added to the centrifugal extractor 001) Figure 16 (As shown by the dashed line), or liquid 002 generated during the operation of centrifugal extractor 001.

[0064] The drive unit 300 is fixed relative to the liquid storage container 200. Specifically, it can be fixedly connected to the machine body 100.

[0065] The filter container 400 is disposed inside the liquid storage container 200 and is driven by the drive device 300, so that the filter container 400 extracts the extractant 003 (such as...) within it by centrifugation. Figure 15 and Figure 16 (As shown) Centrifugal extraction is performed, and the extracted liquid 002 is thrown out of the filter container 400 into the storage container 200 under the action of centrifugal force.

[0066] The spiral pump 510 is in the shape of an annular barrel and is located on the outer side of the filter container 400 in the radial direction r and is driven and connected to the drive device 300 so that the spiral pump 510 can transport the liquid 002 thrown out of the filter container 400 into the liquid storage container 200 back into the filter container 400.

[0067] Furthermore, in other embodiments of this invention, those skilled in the art can omit the screw pump 510 as needed, and allow the water or other liquid 002 to extract the extractant 003 only once. Alternatively, the screw pump 510 can be replaced with any other feasible pumping device, such as an inlet pipe, a water pump, and an outlet pipe connected in sequence. The end of the inlet pipe away from the water pump is positioned at the bottom of the storage container 200, and the end of the outlet pipe away from the water pump is positioned above the filter container 400, so that the water pump can re-pump the liquid 002 ejected from the filter container 400 into the storage container 200 back into the filter container 400.

[0068] The connecting member 600 is used to guide the liquid 002 returned by the screw pump 510 into the filter container 400. The connecting member 600 is disposed radially between the filter container 400 and the screw pump 510, and can abut against both the filter container 400 and the screw pump 510 respectively, specifically by interference fit, so as to increase the structural strength between the filter container 400 and the screw pump 510 through the connecting member 600.

[0069] Those skilled in the art will understand that the arrangement of the connecting member 600 can also increase the radial r dimension of the screw pump 510, thereby improving the pumping capacity of the screw pump 510.

[0070] Furthermore, in other embodiments of this invention, those skilled in the art may omit the connecting member 600 as needed, and allow the liquid 002 pumped by the spiral pump 510 to flow back into the filter container 400. For example, the spiral pump 510 may be made to directly abut against the filter container 400 in the radial direction r.

[0071] The pressure cap 700 is fixed relative to the filter container 400 and includes a bottom small-diameter section 710 located inside the filter container 400. Multiple water inlet holes 711 are provided on the peripheral wall of the bottom small-diameter section 710 (e.g., ...). Figure 12 (As shown). The cap 700 is used to cover the filter container 400 to prevent foreign objects from entering the filter container 400, and to allow the liquid 002 entering the centrifugal extractor 001 to be thrown into the filter container 400 by centrifugal force through the water inlet 711.

[0072] The water supply device 800 is used to receive water or other liquid 002 added by the user to the centrifugal extractor 001 and to supply the water or other liquid 002 to the cap 700 so that the rotating cap 700 throws the water or other liquid 002 into the filter container 400 for extraction by centrifugal force.

[0073] It should be noted that in this invention, the extractant 003 includes coffee powder and / or tea powder. For example, the extractant 003 can be coffee powder or tea powder, or a mixture of coffee powder and tea powder.

[0074] Of course, those skilled in the art may, as needed, include any other feasible powdered substance such as soybean powder, mung bean powder, cocoa powder, lemon, etc.

[0075] The centrifugal extractor 001 of this invention produces a liquid 002 containing dissolved target substances during the extraction of the extractant 003.

[0076] The target substance can be a water-soluble substance in the extract 003. Liquid 002 can be the liquid substance of the extract 003 itself, which can be water or water in which the target substance is dissolved. The water can be hot water, room temperature water or cold water, and its composition can be pure water, tap water, mineral water or water containing specific substances (such as sugar, milk, flavoring, etc.).

[0077] like Figures 1 to 3 As 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 400.

[0078] 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 400 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.

[0079] like Figures 1 to 4 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.

[0080] 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 3 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.

[0081] 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.

[0082] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the bottom wall of the liquid storage container 200 is provided with a clearance hole 202 to avoid the drive device 300, thereby ensuring that the drive device 300 is driven to connect with the filter container 400. The liquid storage container 200 is also provided with an annular retaining edge 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 202.

[0083] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments of this utility model, the liquid storage container 200 is provided with a drain channel 201 to drain the liquid 002 inside the liquid storage container 200. The liquid storage container 200 may also be equipped with a removable plug (not marked in the figure) to open and close the drain channel 201.

[0084] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the liquid storage container 200 is further provided with a plug-in mating structure 220 for installing and fixing the water supply device 800. The water supply device 800 will be described in detail later, and will not be repeated here.

[0085] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the driving device 300 includes a motor 310 disposed on the outside of the liquid storage container 200 and a connector 320 disposed on the inside of the liquid storage container 200. The motor 310 is fixedly connected to the body 100 through its housing, and the motor 310 is fixedly connected to the connector 320 through its rotating shaft. The connector 320 is fixedly connected to the filter container 400, so that the motor 310 drives the filter container 400 to rotate through the connector 320.

[0086] like Figure 4 As shown, in some embodiments of this utility model, the connector 320 includes a drive disk 321 and a driven disk 322 that are plugged together. The drive disk 321 is fixedly connected to the shaft of the motor 310, and the driven disk 322 is fixedly connected to the filter container 400 to facilitate the installation and removal of the filter container 400.

[0087] The fixed connection between the driven disc 322 and the filter container 400 can be any feasible connection method such as screw connection, riveting, welding, bonding, snap-fit, etc.

[0088] In addition, those skilled in the art may, as needed, configure the driven disc 322 and the filter container 400 as an integral component.

[0089] like Figure 4 As shown, in some embodiments of this utility model, the driven disk 322 is provided with a plurality of downwardly extending pins (not marked in the figure), and the drive disk 321 is provided with a plurality of upwardly opening holes (not marked in the figure). The pins can be plugged into the holes to connect the driven disk 322 and the drive disk 321 together.

[0090] like Figure 1 , Figure 2 and Figure 4As shown, in some embodiments of this invention, the filter container 400 includes a large-diameter bottom section 410 and a small-diameter top section 420. The large-diameter bottom section 410 is used to contain the extractant 003. A plurality of filter holes (not marked in the figure) are evenly distributed on the peripheral wall of the large-diameter bottom section 410 to allow the extracted solution to exit the filter container 400 through these filter holes. The small-diameter top section 420 is used to prevent the extractant 003 within the large-diameter bottom section 410 from being ejected from the large-diameter bottom section 410.

[0091] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the cap 700 includes a large-diameter top section 720 and a small-diameter bottom section 710. The large-diameter top section 720 matches the small-diameter top section 420 of the filter container 400, preventing the extractant 003 inside the large-diameter bottom section 410 from being thrown out of the large-diameter bottom section 410. Multiple permeable holes (not marked in the figure) are evenly distributed on the peripheral wall of the small-diameter bottom section 710, allowing the liquid 002 inside the filter container 400 to flow out through these permeable holes or be thrown out into the large-diameter bottom section 410 of the filter container 400.

[0092] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the spiral pump 510 includes a pump housing 511 and a spiral blade 512 disposed within the pump housing 511. The bottom of the pump housing 511 has a water receiving portion (not marked in the figure) extending radially inward along a direction r. The top wall of this water receiving portion is provided with multiple through holes to allow the solution ejected from the filter container 400 to enter the pump housing 511 through these through holes. The top of the pump housing 511 has a downwardly and inwardly inclined sidewall, which is also provided with multiple through holes to allow liquid 002 inside the pump housing 511 to flow out through these through holes.

[0093] Furthermore, the pump housing 511 may include two parts to facilitate the installation of the propeller 512 into the pump housing 511. For example, the pump housing 511 includes a top ring and a bottom ring in the axial z direction that form a sealing connection. After the propeller 512 is installed into the bottom ring, the top ring is then installed onto the bottom ring. This sealing connection may be welded, threaded, plugged, etc.

[0094] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in some embodiments of this utility model, a drain hole 5111 is provided at the bottom of the pump housing 511. A control valve 520 is installed at the drain hole 5111. The control valve 520 is used to control the opening and closing of the drain hole 5111 so that after extraction, the drain hole 5111 is opened so that the liquid 002 inside the pump housing 511 and the top side of the pump housing 511 flows through the drain hole 5111 to the storage container 200, and is finally discharged from the centrifugal extractor 001 from the drain channel 201 of the storage container 200.

[0095] The control valve 520 can be any feasible valve, such as a solenoid valve or a valve that can be attracted by magnetic force. Exemplarily, the control valve 520 includes a valve body mounted on the pump housing 511, a valve core slidably connected to the valve body, a spring that causes the valve core to close the control valve 520, and an electromagnet provided on the liquid storage container 200. When the electromagnet is energized, the electromagnetic force overcomes the spring force and causes the valve core to open the control valve 520.

[0096] Furthermore, to align the control valve 520 with the electromagnet, a position sensor can be configured on the centrifugal extractor 001 to detect the relative position of the control valve 520 and the electromagnet. For example, the position sensor may also include a magnet mounted on the pump housing 511 and a Hall sensor mounted on the liquid storage container 200. When the Hall sensor detects the magnet, it determines that the control valve 520 is aligned with the electromagnet and controls the motor 310 to stop rotating.

[0097] from Figure 5 As can be seen from the above, in some embodiments of this utility model, the rotor 512 can be a spiral strip structure.

[0098] like Figure 1 , Figure 2 , Figure 4 and 6 As shown, in some embodiments of this utility model, the connecting member 600 defines a lower cavity 601 and an upper cavity 602. The inner peripheral wall of the lower cavity 601 is adapted to the bottom large-diameter section 410 of the filter container 400, specifically, it can be a radial abutment, such as an interference fit. The inner peripheral wall of the lower cavity 601 is provided with a through hole aligned with the filter hole of the filter container 400, so that liquid 002 ejected from the filter container 400 enters the lower cavity 601 of the connecting member 600. The bottom wall of the lower cavity 601 abuts against the water receiving portion of the pump housing 511, and the bottom wall of the lower cavity 601 is provided with a through hole aligned with the through hole on the water receiving portion, so that the lower cavity 601 enters the pump housing 511. The outer peripheral wall of the lower cavity 601 abuts against the inner peripheral wall of the pump housing 511 to increase the connection strength between the filter container 400, the connecting member 600, and the screw pump 510.

[0099] Furthermore, the outer peripheral wall of the upper cavity 602 abuts against the inclined sidewall of the top of the pump housing 511, and the outer peripheral wall of the upper cavity 602 is provided with a through hole aligned with the through hole on the inclined sidewall, so that the liquid 002 in the pump housing 511 can enter the upper cavity 602. The inner peripheral wall of the upper cavity 602 abuts against the top small-diameter section 420 of the filter container 400 to increase the connection strength between the filter container 400, the connecting member 600, and the screw pump 510. The bottom sidewall of the upper cavity 602 abuts against the top wall of the bottom large-diameter section 410 of the filter container 400, and the bottom sidewall of the upper cavity 602 is provided with a through hole aligned with the through hole on the top wall of the bottom large-diameter section 410, so that the liquid 002 in the upper cavity 602 can flow back to the filter container 400.

[0100] like Figures 7 to 10 As shown, in some embodiments of this utility model, the water supply device 800 includes a water injection container 810 fixed relative to the liquid storage container 200 and a water supply system 820 disposed in the water injection container 810. The water supply system 820 is used to supply water to the water injection container 810, and the water injection container 810 is used to deliver the received water to the filter container 400.

[0101] In addition, in other embodiments of this utility model, those skilled in the art may omit one of the liquid storage container 200 and the water supply system 820 as needed.

[0102] like Figure 9 As shown, in some embodiments of this utility model, the water injection container 810 defines an installation cavity 8101 and a water injection cavity 8102 located on the bottom side of the installation cavity 8101. The radial dimension r of the installation cavity 8101 is larger than the radial dimension r of the water injection cavity 8102. The water supply system 820 is arranged inside the installation cavity 8101.

[0103] like Figure 9 As shown, in some embodiments of this utility model, the water injection container 810 is fixed relative to the liquid storage container 200 and includes a water injection part 810a inserted into the bottom small diameter section 710. The peripheral wall of the water injection part 810a is provided with a plurality of water injection holes 8113 so that the liquid 002 in the water injection container 810 flows out through the water injection holes 8113, and the forward rotating pressure cap 700 draws the liquid 002 flowing out from the water injection holes 8113 through the water inlet hole 711, thereby causing the liquid 002 to be thrown towards the extractant 003 under the action of centrifugal force.

[0104] like Figures 7 to 10As shown, in some embodiments of this utility model, the water injection container 810 includes a bottom container 811 fixed relative to the liquid storage container 200, a middle container 812 with a drain hole 81201, a shut-off valve 813, and a top cover 814 for closing the middle container 812. The middle container 812 is detachably installed inside the bottom container 811. The shut-off valve 813 closes the drain hole 81201 when the middle container 812 is not installed inside the bottom container 811, and is driven by the bottom container 811 to open the drain hole 81201 when the middle container 812 is installed inside the bottom container 811, so that the liquid 002 (which may be water) in the water injection container 810 enters the filter container 400.

[0105] Continue reading Figures 7 to 10 In some embodiments of this utility model, both the mounting cavity 8101 and the water injection cavity 8102 are formed inside the middle container 812, and the mounting cavity 8101 is covered by the top cover 814. Furthermore, the water injection part 810a corresponds to the water injection cavity 8102, and the water injection hole 8113 is also formed at the bottom of the bottom container 811.

[0106] like Figures 7 to 11 As shown, in some embodiments of this utility model, the top of the bottom container 811 is provided with an annular baffle 8111 extending outward along the radial direction r, and the bottom side of the annular baffle 8111 is provided with a plug-in structure 81111. The plug-in structure 81111 is adapted to the plug-in mating structure 220 on the liquid storage container 200 so that the bottom container 811 is plugged together in the axial direction z through the plug-in structure 81111 and the plug-in mating structure 220, thereby preventing the bottom container 811 from shaking in the radial direction r and avoiding contact between the bottom container 811 and the components driven by the driven device 300.

[0107] like Figure 1 , Figure 4 , Figures 8 to 11 As shown, in some embodiments of this utility model, the insertion structure 81111 is a protrusion, and the insertion mating structure 220 is a slot. Alternatively, those skilled in the art can, as needed, provide a slot for the insertion structure 81111 and a protrusion for the insertion mating structure 220.

[0108] like Figures 8 to 12 As shown, in some embodiments of this utility model, the bottom container 811 is provided with an upwardly protruding top post 8112, through which the sealing valve 813 is opened.

[0109] like Figure 9 and Figure 10As shown, in some embodiments of this utility model, a blind tube 8121 extending upward is provided at the bottom of the central container 812, and a drain hole 81201 is formed at the top of the blind tube 8121. In the assembled state, the top post 8112 is inserted into the blind tube 8121 and fits with the blind tube 8121 with a clearance.

[0110] like Figures 7 to 9 As shown, in some embodiments of this utility model, the sealing valve 813 includes a sealing plug 8131 located inside the central container 812 and a sliding rod 8132 penetrating the leakage hole 81201. Under the action of its own gravity, the sealing valve 813 seals the leakage hole 81201 through the sealing plug 8131.

[0111] Continue reading Figures 7 to 9 In some embodiments of this utility model, the slide rod 8132 slides in contact with the peripheral wall of the drain hole 81201. Furthermore, the cross-section of the slide rod 8132 is different from the cross-section of the drain hole 81201 to ensure that liquid 002 can flow out from the drain hole 81201.

[0112] like Figure 7 and Figure 8 As shown, in some embodiments of this utility model, the cross-section of the slide bar 8132 is cross-shaped, and the cross-section of the drain hole 81201 is circular.

[0113] In addition, in other embodiments of this utility model, those skilled in the art can also set the cross-section of the slide bar 8132 into any feasible shape such as sheet-like, triangular, or pentagonal as needed.

[0114] like Figures 7 to 9 As shown, in some embodiments of this utility model, the sealing valve 813 includes a stop structure 8133 disposed on the side of the slide rod 8132 away from the sealing plug 8131. The stop structure 8133 interferes with the central container 812 to prevent the sealing valve from coming out of the leakage hole 81201.

[0115] In this design, one of the stop structure 8133 and the sealing plug 8131 is integrally formed with the slide rod 8132, while the other is fixedly connected to the slide rod 8132. For example, the stop structure 8133 is integrally formed with the slide rod 8132, and the rubber plug is engaged with the slide rod 8132 (similar to the piston and piston rod of a syringe).

[0116] Alternatively, those skilled in the art may, as needed, configure the stop structure 8133 as a deformable conical structure so that the stop structure 8133 can pass through the drain hole 81201 from the inside of the middle container 812 to the outside of the middle container 812.

[0117] like Figure 9 and Figure 13As shown, in some embodiments of this utility model, in the assembled state, an annular flow channel 8104 is defined between the bottom container 811 and the middle container 812, and the annular flow channel 8104 communicates with the drain hole 81201. Furthermore, the annular flow channel 8104 also communicates with the water inlet hole 8113 formed on the bottom container 811, so that the liquid 002 in the middle container 812 flows out of the bottom container 811 through the drain hole 81201, the annular flow channel 8104, and the water inlet hole 711. As can be seen from the figure, the water inlet hole 8113 is formed on the outer wall of the annular flow channel 8104.

[0118] like Figure 9 and Figure 13 As shown, in some embodiments of this utility model, the annular flow channel 8104 includes an inner ring portion 81041, a bottom ring portion 81042, and an outer ring portion 81043 connected in sequence. The inner ring portion 81041 is defined by the top post 8112 and the blind tube 8121. The bottom ring portion 81042 is defined by the bottom wall of the bottom container 811 and the bottom wall of the middle container 812. The outer ring portion 81043 is defined by the peripheral wall of the bottom of the bottom container 811 and the peripheral wall of the bottom of the middle container 812. The inner ring portion 81041 is located inside the outer ring portion 81043. The bottom ring portion 81042 is located on the bottom side of the inner ring portion 81041 and the outer ring portion 81043. The water injection hole 8113 is formed on the outer side wall of the outer ring portion 81043. The liquid inlet (i.e., the water leakage hole 81201) of the annular flow channel 8104 is formed on the top side of the inner ring portion 81041.

[0119] In some embodiments of this utility model, the annular guide channel 8104 guides the liquid 002 in the water injection container 810 to the water injection hole 8113 through the principle of communicating vessels and / or capillary phenomenon. In this way, the flow rate of the liquid 002 is controlled, and the water injection hole 8113 can be set at any position on the peripheral wall of the water injection part 810a.

[0120] like Figure 13 As shown, the radial width b of the annular guide channel 8104 is selected from any value from 0.5 mm to 5 mm. For example, b can be any feasible value such as 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 5 mm, etc.

[0121] like Figures 9 to 13 As shown, in some embodiments of this utility model, the height of the inner ring portion 81041 can be less than the height of the outer ring portion 81043, so that the liquid 002 in the middle container 812 can be emptied as much as possible.

[0122] Optionally, the distribution density of the water injection holes 8113 at the bottom of the water injection section 810a can be less than the distribution density of the water injection holes 8113 at the top of the water injection section 810a, so that the liquid 002 in the outer ring section 81043 flows out evenly from all the water injection holes 8113, and avoids the liquid 002 in the outer ring section 81043 being discharged in large quantities from the bottom of the water injection section 810a.

[0123] Alternatively, the distribution density of the water inlet holes 711 at the bottom of the small diameter section 710 is less than that at the top of the small diameter section 710, so that the small diameter section 710 can uniformly draw liquid 002 in the axial z direction through the water inlet holes 711 thereon, and uniformly spray the liquid 002 onto the extractant 003.

[0124] like Figure 14 As shown, in some embodiments of this utility model, the water inlet 711 is inclined from its inner end to its outer end in the direction of reversal of the pressure cap 700, so that the water inlet 711 forms a force that attracts the liquid 002 flowing out of the water injection hole 8113 during the forward rotation of the pressure cap 700, thereby drawing the liquid 002 into the water injection hole 8113.

[0125] Those skilled in the art will understand that by tilting the inlet hole 711 from its inner end to its outer end in the reverse direction of the pressure cap 700, the small-diameter section 710 at the bottom, through the inlet hole 711, functions as a centrifugal pump. This allows the inlet hole 711 to generate a force that attracts the liquid 002 flowing from the injection hole 8113 as the pressure cap 700 rotates forward, drawing the liquid 002 into the injection hole 8113. Simultaneously, the forward-rotating pressure cap 700 creates a negative pressure on the outside of the injection section 810a, increasing the outflow velocity of the liquid 002 within the injection section 810a and ensuring the flow rate of the liquid 002.

[0126] Continue reading Figure 14 The water injection section 810a and the bottom small diameter section 710 are fitted with a clearance to avoid noise caused by sliding contact between the water injection section 810a and the bottom small diameter section 710, which would affect the user's experience.

[0127] Furthermore, the radial distance d between the water injection section 810a and the bottom small-diameter section 710 is greater than 0 and less than or equal to 3 mm. In particular, the radial distance d between the water injection section 810a and the bottom small-diameter section 710 is greater than 0.5 mm and less than or equal to 1.5 mm, so that the liquid 002 flowing out from the water injection hole 8113 can be promptly absorbed by the water inlet hole 711. The specific value of d can be 0.5 mm, 0.8 mm, 1.2 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc.

[0128] Those skilled in the art will understand that, due to the surface tension of liquid 002, liquid 002 will have a certain thickness when flowing. Furthermore, when liquid 002 slowly flows out through the hole, it forms water droplets of a certain size (typically between 0.5 mm and 5 mm). Therefore, by ensuring that the radial distance d between the water injection section 810a and the bottom small-diameter section 710 is greater than 0 and less than or equal to 3 mm, this invention ensures that the cap 700 can attract liquid 002 through the water inlet hole 711, while preventing the water flowing from the water injection hole 8113 from flowing to the bottom of the water injection container 810 under gravity. This would result in more liquid 002 being thrown towards the bottom of the extractant 003 and less towards the top, leading to uneven extraction of the extractant 003.

[0129] like Figures 7 to 10 As shown, in some embodiments of this utility model, the water supply system 820 includes a cold water tank 8211, a cold water outlet pipe 8212, a hot water tank 8221, and a hot water outlet pipe 8222. The cold water tank 8211 and the hot water tank 8221 are both arranged on the bottom wall of the mounting cavity 8101. The cold water outlet pipe 8212 is connected to the cold water tank 8211 and extends to the top of the water injection cavity 8102. The hot water outlet pipe 8222 is connected to the hot water tank 8221 and extends to the top of the water injection cavity 8102.

[0130] In this invention, the portions of the bottom container 811 and the middle container 812 located on the bottom side of the mounting cavity 8101 can both be referred to as the bottom wall of the mounting cavity 8101.

[0131] Continue reading Figures 7 to 10 In some embodiments of this utility model, the cold water outlet pipe 8212 is disposed on the bottom side of the cold water tank 8211, and the hot water outlet pipe 8222 is disposed on the bottom side of the hot water tank 8221. The bottom wall of the mounting cavity 8101 and the peripheral wall of the water injection cavity 8102 are defined with clearance notches 8103 for avoiding the cold water outlet pipe 8212 and the hot water outlet pipe 8222.

[0132] Continue reading Figures 7 to 10 In some embodiments of this invention, both the cold water tank 8211 and the hot water tank 8221 are arranged in annular shape and are arranged radially along a direction r. Furthermore, the centrifugal extractor 001 also includes a semiconductor cooling module 831 disposed between the cold water tank 8211 and the hot water tank 8221. The semiconductor cooling module 831 is used to cool the cold water tank 8211 and heat the hot water tank 8221, thereby producing hot water while simultaneously producing cold water, improving energy utilization. This semiconductor cooling module 831 is also arranged in annular shape.

[0133] In addition, in other embodiments of this utility model, those skilled in the art can also set the cold water tank 8211, the hot water tank 8221 and the semiconductor refrigeration module 831 into other feasible shapes, such as C-shape, as needed.

[0134] Continue reading Figures 7 to 10 In some embodiments of this utility model, the water supply system 820 may further include a cold water valve 8213 connected in series with the cold water outlet pipe 8212 and a hot water valve 8223 connected in series with the hot water outlet pipe 8222, so as to control whether the water in the cold water tank 8211 flows to the water injection chamber 8102 through the cold water valve 8213, and to control whether the water in the hot water tank 8221 flows to the water injection chamber 8102 through the hot water valve 8223.

[0135] Continue reading Figures 7 to 10 In some embodiments of this utility model, the water supply system 820 may further include a normal temperature water tank 823 disposed on the top side of the cold water tank 8211 and the hot water tank 8221, a cold water connecting pipe 8214 disposed between the cold water tank 8211 and the normal temperature water tank 823, and a hot water connecting pipe 8224 disposed between the hot water tank 8221 and the normal temperature water tank 823, so as to replenish the cold water tank 8211 with water through the normal temperature water tank 823 when the water in the cold water tank 8211 is insufficient; and to replenish the hot water tank 8221 with water through the normal temperature water tank 8223 when the water in the hot water tank 8221 is insufficient.

[0136] Continue reading Figures 7 to 10 In some embodiments of this utility model, the water supply system 820 may further include a cold water pump 8215 connected in series between the cold water tank 8211 and the ambient temperature water tank 823, and a hot water pump 8225 connected in series between the hot water tank 8221 and the ambient temperature water tank 823, so that the cold water pump 8215 can transport water from the ambient temperature water tank 823 to the cold water tank 8211, and the hot water pump 8225 can transport water from the ambient temperature water tank 823 to the hot water tank 8221. Those skilled in the art will understand that, with the cold water pump 8215 and the hot water tank installed, the height of the ambient temperature water tank 823 can be kept no higher than the heights of the cold water tank 8211 and the hot water tank 8221.

[0137] from Figures 7 to 10 As can be seen, the water supply system 820 (except for the cold water outlet pipe 8212, cold water valve 8213, hot water outlet pipe 8222, and hot water valve 8223 located within the clearance gap 8103) is arranged within the middle container 812, and is also located at or above the filter container 400 in the axial z direction, specifically within the top small-diameter section 420. Both the bottom container 811 and the middle container 812 are provided with clearance gaps 8103 to allow passage of the cold water outlet pipe 8212 and the hot water outlet pipe 8222.

[0138] Furthermore, although not shown in the figure, temperature sensors can be installed in both the cold water tank 8211 and the hot water tank 8221 to detect whether the temperature in each tank has reached a preset value. The preset value for the cold water tank 8211 can be any feasible value such as 1℃, 2℃, 3℃, 4℃, 8℃, or 10℃. The preset value for the hot water tank 8221 can be any feasible value such as 100℃, 92℃, 93℃, 95℃, or 88℃. Liquid level sensors can also be installed in both the cold water tank 8211 and the hot water tank 8221 to detect whether the water level is sufficient. If the water level is insufficient, the corresponding cold water pump 8215 or hot water cup will be activated to draw water from the ambient temperature water tank 823.

[0139] like Figure 7 As shown, in some embodiments of this utility model, a plurality of support protrusions 8122 are provided on the peripheral wall of the mounting cavity 8101. Specifically, the support protrusions 8122 are disposed on the inner peripheral surface of the central container 812. Further, the support protrusions 8122 include a recessed axial z-support surface 81221 to support the ambient temperature water tank 823 in the axial z direction. The support protrusions 8122 may also include a radial r-stop surface 81222 located on the top side of the support surface 81221 to fix the ambient temperature water tank 823 in the radial r direction.

[0140] Those skilled in the art will understand that the support protrusion 8122 prevents the ambient temperature water tank 823 from shaking. Furthermore, those skilled in the art may, as needed, provide a groove along the circumferential θ edge of the bottom wall of the ambient temperature water tank 823 so that the support protrusion 8122 is embedded within the groove, thereby further improving the stability of the ambient temperature water tank 823.

[0141] like Figures 7 to 10 As shown, in some embodiments of this utility model, a water inlet 8231 is provided on the top side of the ambient temperature water tank 823, allowing the user to add water to the ambient temperature water tank 823 through the water inlet 8231. The top cover 814 is provided with a downwardly protruding tank plug 8141, which is used to close the water inlet 8231. The top cover 814 closes the water inlet 8231 while simultaneously covering the central container 812.

[0142] like Figure 9 , Figure 11 and Figure 12As shown, in its assembled state, the filter container 400 is fixedly connected to the driven disc 322 of the drive device 300. This connection can be achieved through welding, riveting, snap-fitting, threaded connection, etc. The filter container 400, connecting member 600, and screw pump 510 are arranged sequentially in the radial direction r and fixed relative to each other; for example, adjacent components of the filter container 400, connecting member 600, and screw pump 510 are interference-fitted. The gland 700 is detachably inserted into the filter container 400, specifically with a slight interference fit. The bottom container 811 is detachably mounted to the liquid storage container 200 via a plug-in structure 81111 and a plug-in fitting structure 220, and a portion of the filter container 400 is embedded in the gland 700, while also having a clearance fit with both the gland 700 and the filter container 400. The middle container 812 and its internal water supply system 820 are embedded within the bottom container 811. The top cover 814 is detachably installed on the middle container 812, thereby sealing the water inlet 8231 of the ambient temperature water tank 823.

[0143] Furthermore, although not shown in the figure, in this utility model, the electrical components of the water supply system 820 and the semiconductor cooling module 831 can be connected to the power supply or power line on the body 100 via a power cord. Specifically, corresponding wiring holes can be provided on the water injection container 810 and / or the liquid storage container 200.

[0144] The following reference Figure 9 , Figures 11 to 16 The working principle of the centrifugal extractor 001 in some embodiments of this utility model will be briefly explained.

[0145] When cold extraction is required, first remove the cap 700 and the water supply device 800, and fill the extractant 003 into the filter container 400. Then, pre-run the motor 310 for a period of time (e.g., 5S, 10S, 15S, etc.) and stop it, and then reinstall the cap 700 and the water supply device 800.

[0146] Then, open the top cover 814, add enough water to the ambient temperature water tank 823, and then close the top cover 814. Start the cold water pump 8215 and the hot water pump 8225 to inject the water in the ambient temperature water tank 823 into the cold water tank 8211 and the hot water tank 8221, respectively. Power on the semiconductor cooling module 831 to cool the cold water in the cold water tank 8211 and heat the hot water in the hot water tank 8221.

[0147] When the water temperature in the cold water tank 8211 drops to a preset value, the power supply to the semiconductor cooling module 831 can be stopped, and the cold water valve 8213 can be opened to allow the cold water in the cold water tank 8211 to be discharged into the water injection section 810a in the middle container 812, and then flow out of the bottom container 811 through the water leakage hole 81201, the annular guide channel 8104 and the water injection hole 8113.

[0148] Simultaneously, the motor 310 is controlled to rotate forward, thereby driving the filter container 400, the pressure cap 700, the screw pump 510, and the connecting component 600 to rotate together. The rotating pressure cap 700, with the help of its inclined water inlet 711, functions as a centrifugal pump, thereby creating a force in the water inlet 711 to attract cold water (liquid 002) flowing out from the water injection hole 8113, drawing the cold water into the water injection hole 8113, and then throwing the cold water radially r toward the extractant 003.

[0149] Under the influence of centrifugal force and gravity, cold water passes through the extractant 003 and forms a solution (liquid 002), which then flows through the lower cavity 601 of the connecting member 600 to the screw pump 510. The rotating screw pump 510 delivers the solution to the upper cavity 602 of the connecting member 600, and then it re-enters the filter container 400 to extract the extractant 003 in the filter container 400 again.

[0150] After extraction is complete, motor 310 stops rotating, control valve 520 is opened, and the user opens the plug at drain channel 201 to allow the final solution to be discharged through drain channel 201.

[0151] In this invention, the extraction time of the centrifugal extractor 001 can be counted to determine whether the extractant 003 has been extracted. Alternatively, the extraction time of the extractant 003 can be counted to determine whether the concentration of the solution in the storage container 200 has reached the value set by the user.

[0152] When hot extraction is required, the steps are basically the same as those for cold extraction, except that the hot water in the hot water tank 8221 is supplied to the water injection chamber 8102.

[0153] It should be noted that the above-described usage method is only for helping those skilled in the art to understand the centrifugal extractor 001 of this utility model, and does not mean that the centrifugal extractor 001 of this utility model can only have the above-described usage method.

[0154] Based on the foregoing description, those skilled in the art will understand that the centrifugal extractor 001 of this utility model not only has the functions of cold extraction and hot extraction, but also has a better extraction effect.

[0155] Furthermore, in other embodiments of this utility model, those skilled in the art may omit the components related to cold or hot extraction in the centrifugal extractor 001 as needed. See below for further details. Figures 17 to 19 Let's illustrate with examples.

[0156] like Figure 17As shown, in some embodiments of this invention, the components related to cold extraction in the centrifugal extractor 001 are omitted, and the centrifugal extractor 001 includes a heating device 840 for heating water in the hot water tank 8221. Furthermore, this heating device 840 is an electric heating wire 841 disposed on the outside or inside of the hot water tank 8221. Additionally, the heating device 840 may also include a portion disposed within the upper cavity 602 of the connecting member 600 (e.g., Figure 6 As shown), the heating device 840 heats the liquid 002 within the upper cavity 602 to ensure the thermal quenching effect. This heating device 840 can be an electric heating wire 841 or... Figure 18 The electromagnetic coil 842 shown is shown.

[0157] like Figure 18 As shown, in some other embodiments of this utility model, the heating device 840 is an electromagnetic coil 842 disposed outside the hot water tank 8221. Furthermore, a metal structure 843 is provided on the hot water tank 8221 to be heated by the electromagnetic coil 842.

[0158] like Figure 19 As shown, in some other embodiments of this invention, the components related to hot extraction in the centrifugal extractor 001 are omitted, and the centrifugal extractor 001 includes a heat sink 832 to absorb the heat generated when the semiconductor refrigeration module 831 cools the cold water tank 8211.
