Description

Technical Field

[0001] This invention relates to the field of separation technology, and in particular to an extraction machine for preparing beverages such as tea and coffee, and its intelligent tea extraction control method. Background Technology

[0002] Existing extraction devices for preparing beverages such as tea and coffee typically consist of an extraction container and a receiving container. During use, the user places the raw material to be extracted into the extraction container and adds hot or room temperature water. After soaking or filtering for a period of time, the extract flows into the receiving container through a discharge structure at the bottom of the extraction container. Existing extraction devices typically employ the following discharge methods: gravity drip filtration or direct discharge with continuous discharge during the extraction process; opening or closing the discharge port using valves, plugs, or other opening and closing mechanisms after soaking; and controlling the discharge through a combination of the main unit structure and the extraction container. Some devices also include timing or indicator components to help users determine the optimal operating time.

[0003] However, the existing technology still has the following shortcomings: (1) In many solutions, the opening and closing of the liquid outlet still mainly depends on manual operation. Users need to time the opening and closing actions themselves and manually perform the opening and closing actions. There are many operation steps, and it is difficult to keep the liquid outlet timing consistent, which affects the stability and repeatability of the extraction effect. (2) Some liquid outlet control structures require multiple parts to cooperate to complete the opening and closing actions. They are more sensitive to assembly accuracy, fitting gaps and wear. After a long service period, problems such as unsmooth operation, incomplete opening and closing or decreased reliability may occur. (3) Most of the existing extraction cups are one-piece molded structures. The inside of the cup body and the liquid outlet channel at the bottom are not easy to disassemble and clean. After use, residues are easy to accumulate, which is not conducive to maintaining cleanliness and hygiene. (4) There is a lack of effective buffering or limiting means for the flow rate and velocity during the liquid outlet stage. When the instantaneous flow rate of the liquid outlet is too high, the liquid splashing during the liquid receiving process is easy to occur, which affects the user experience and increases the cleaning and maintenance burden. (5) The water injection process usually lacks intuitive prompts or quantitative feedback related to the amount of water injected. Users often rely on visual inspection or experience to control the amount of water injected, which can easily lead to deviations, resulting in fluctuations in extraction concentration and taste, and poor repeatability of preparation results. Summary of the Invention

[0004] To at least solve one of the aforementioned technical problems in the prior art, a first objective of the present invention is to provide an extraction machine. To at least solve one of the aforementioned technical problems in the prior art, a second objective of the present invention is to provide an intelligent tea extraction control method utilizing the extraction machine.

[0005] The first objective of this invention is achieved as follows:

[0006] An extraction machine includes a main unit and an extraction cup. The main unit includes a base, a support, and a control component. The support is disposed above the base, and a liquid receiving container placement area is formed between the support and the base for placing a liquid receiving container. The support has a channel communicating with the liquid receiving container placement area.

[0007] The extraction cup includes a cup body, which comprises an upper cup body and a lower cup body. The top of the upper cup body is open, and the lower end of the upper cup body is provided with a locking channel. The cross-sectional dimension of the locking channel gradually decreases along the insertion direction. The top of the lower cup body is open, and the shape of the upper end of the lower cup body matches the locking channel. The outer diameter of the upper end of the lower cup body is smaller than the inlet diameter of the locking channel and larger than the outlet diameter of the locking channel. The bottom of the lower cup body is provided with a tube that cooperates with the channel and communicates with the cup body.

[0008] The lower cup body is inserted into the upper cup body through the top opening of the upper cup body and is locked in place by the locking channel, thereby assembling the cup body; the tube body is provided with a ball that can move within the tube body and can be attracted by magnetic force, and the lower end of the tube body has a drain port with a diameter smaller than the diameter of the ball; the cup body is placed on the support base and the tube body is inserted into the channel, with the drain port facing the liquid receiving container placement area;

[0009] When the sphere is in the first position, the drain port is closed; when the sphere is in the second position, it moves away from the drain port to open the drain port. The support is provided with a magnetic component on the outside of the channel. The magnetic component is used to apply a magnetic force to the sphere to drive the sphere to move between the first position and the second position. The control component is used to control the magnetic force applied by the magnetic component to the sphere to realize the opening and closing of the drain port.

[0010] By incorporating a magnetically attracted and movable sphere within the extraction cup tube to close / open the outlet, and simultaneously installing a magnetic component on the outside of the main unit channel with the magnetic force state regulated by a control component, the outlet can be controlled to open and close under command. This reduces inconsistencies in outlet timing caused by manual timing and opening / closing. Furthermore, magnetic drive replaces multi-component mechanical opening and closing mechanisms, improving the stability and long-term reliability of the opening and closing action. In addition, the upper and lower cups are clamped together, allowing the extraction cup to be disassembled for easy cleaning and maintenance of the interior and bottom outlet channel, thus mitigating the problem of residue buildup caused by the inconvenience of cleaning integrated cups.

[0011] The primary objective of this invention can also be achieved using the following technical measures:

[0012] Furthermore, the extraction cup also includes a sealing ring, and the upper outer wall of the lower cup body is provided with a locking groove for accommodating the sealing ring. The sealing ring is fitted and confined within the locking groove. When the upper end of the lower cup body is locked in the locking channel, the sealing ring abuts against the inner wall of the locking channel and the upper outer wall of the lower cup body to seal the gap between the inner wall of the locking channel and the upper end of the lower cup body.

[0013] A sealing ring retaining groove is set on the upper outer wall of the lower cup body, and the sealing ring is installed in a limiting position. When the lower cup body is inserted into the retaining channel, the sealing ring forms a reliable abutment seal with the inner wall of the retaining channel and the outer wall of the lower cup body. This can effectively reduce the risk of gaps forming at the joints of the detachable structure, improve the sealing reliability and consistency after assembly, and reduce the impact on user experience and hygiene caused by repeated disassembly or long-term use, such as leakage and loosening.

[0014] Furthermore, it also includes an elastic flow restrictor, which has a splash-proof flow restrictor channel and a plug-in section. The plug-in section is inserted into the drain port to connect the elastic flow restrictor to the lower cup body, and the splash-proof flow restrictor channel communicates with the drain port. The splash-proof flow restrictor channel is used to generate flow damping for the liquid discharged through the drain port.

[0015] An elastic flow restrictor with a splash-proof flow restriction channel is installed at the drain outlet and connected to the drain outlet through a plug section. This causes flow damping of the discharged liquid within the flow restriction channel, which can buffer and limit the outflow velocity, thereby reducing splashing caused by excessive instantaneous outflow velocity, improving the stability of the liquid receiving process, and reducing the burden of cleaning and maintenance.

[0016] Furthermore, the control component includes a circuit board and a switch, the switch being used to manually control the action of the magnetic component; the circuit board is provided with a timing control unit, the timing control unit being used to control the action of the magnetic component to open the drain port when a preset soaking time is reached.

[0017] By setting up a circuit board and a switch, the magnetic component can be manually controlled by the switch, while the timing control unit on the circuit board can automatically trigger the magnetic component to open the drain port when the preset soaking time is reached. This changes the critical timing of liquid discharge from "relying on the user to judge by timing" to "automatically executing according to the preset time", thereby reducing the number of operation steps and improving the consistency and repeatability of the extraction process, while retaining the necessary ability for manual intervention.

[0018] Furthermore, the magnetic component includes a permanent magnet and a driving mechanism for driving the permanent magnet closer to or further away from the channel; the driving mechanism includes a reversible micromotor and a transmission component, the output end of the micromotor being connected to the transmission component, the transmission component being used to drive the permanent magnet closer to or further away from the channel; the circuit board is electrically connected to the micromotor, the circuit board being used to output a positive driving signal to the micromotor to drive the micromotor to rotate forward, thereby causing the permanent magnet to move closer to the channel, and to output a reverse driving signal to the micromotor to drive the micromotor to rotate in reverse, thereby causing the permanent magnet to move away from the channel; the positive driving signal and / or the reverse driving signal output by the circuit board to the micromotor are driving pulses of a preset duration.

[0019] By using a micro motor and transmission components to drive the permanent magnet to move closer to or further away from the channel, and controlling the forward / reverse rotation of the micro motor by outputting forward / reverse drive signals from the circuit board, the displacement of the permanent magnet and the attraction / release process of the sphere can be more controllable. This reduces the problems of unsmooth or incomplete opening and closing caused by the multi-component coordination and sensitivity to assembly precision and wear of traditional mechanical opening and closing mechanisms. Furthermore, setting the drive signal to a drive pulse with a preset duration helps to ensure that the stroke and opening and closing result of each action are stable and consistent, thus improving the reliability of opening and closing.

[0020] Furthermore, it also includes at least one support rod and an alerting device. The base includes a weighing chassis, the lower end of the support rod is connected to the weighing chassis, and the upper end of the support rod is connected to the support base. The support rod, the support base, and the weighing chassis form a placement area for the liquid receiving container. The weighing chassis and the alerting device are electrically connected to the circuit board. The weighing chassis is used to detect the weight applied to the weighing chassis and output a weight signal to the circuit board. The circuit board is used to control the operation of the alerting device according to the weight signal. The alerting device includes a light-emitting unit and a sound-emitting unit. The light-emitting unit is used to emit light of a preset color, and the sound-emitting unit is used to output a prompt tone, voice information, and / or music signal.

[0021] The weighing chassis detects the weight of the liquid receiving container and the liquid it carries, and outputs a weight signal to the circuit board. The circuit board then controls the reminder device to light up and / or sound an alarm based on the weight signal. This provides quantitative feedback and timely prompts for the water injection process, reducing the deviation caused by users relying on visual estimation or experience to control the amount of water injected. This improves the repeatability and stability of the preparation process and lowers the operating threshold.

[0022] Furthermore, it also includes a button assembly, which includes an insulating component, a plated button, and a spring; the support rod is a plated support rod, which has a mounting hole, and the insulating component is disposed in the mounting hole and has a button through hole; the plated button includes a button head and a connecting foot, the connecting foot is disposed on the back of the button head, and the button head and the connecting foot form a receiving cavity, the connecting foot passes through the button through hole and is connected to the support base, and the button head is located outside the mounting hole; the insulating component is located between the plated support rod and the plated button to electrically insulate the plated button from the plated support rod; the switch is a touch switch, the spring is disposed in the receiving cavity, one end of the spring abuts against the button head, and the other end of the spring abuts against and is electrically connected to the sensing end of the touch switch, thereby electrically connecting the plated button to the sensing end via the spring.

[0023] By isolating the plated button from the plated support rod with an insulating component and using a spring to achieve stable contact and electrical connection between the plated button and the touch switch sensing end, a more reliable triggering path can be formed in metal appearance parts and compact assembly environments. This reduces the impact of false triggering or unstable triggering on manual control of liquid dispensing, and improves the consistency and reliability of response during manual operation.

[0024] Furthermore, the base also includes a base plate, the weighing chassis includes a support plate and a weighing sensor, one end of the weighing sensor is connected to the support plate, the other end of the weighing sensor is connected to the base plate, the support rod is connected to the support plate, and the weighing sensor is electrically connected to the circuit board.

[0025] By forming a relatively clear force transmission structure with a base plate, a support plate, and a load cell, one end of the load cell is connected to the support plate and the other end is connected to the base plate. The support rod is connected to the support plate, which allows the load to act more stably on the load cell, reduces the fluctuation of the weighing signal, and improves the accuracy and stability of weight detection. This provides a reliable data basis for subsequent weight threshold-based prompting control.

[0026] Furthermore, the host is equipped with a parameter acquisition device, which is electrically connected to the circuit board. The parameter acquisition device is used to read the extraction parameters recorded in the external carrier and / or receive the extraction parameters sent by the external terminal, and transmit the read or received extraction parameters to the circuit board. The extraction parameters include at least water injection parameters and / or extraction time parameters. The circuit board stores a liquid receiving container in-situ threshold and a water injection target weight threshold corresponding to the water injection parameters. The circuit board is used to acquire the weight signal and control the working state of the reminder device based on the comparison result of the weight signal with the liquid receiving container in-situ threshold and the water injection target weight threshold. The circuit board is also used to output a drain control signal based on the extraction time parameter to control the drive mechanism to move the permanent magnet closer to or further away from the channel, thereby controlling the magnetic force of the magnetic component on the sphere to open or close the drain port.

[0027] The parameter acquisition device reads / receives external extraction parameters and transmits them to the circuit board. The circuit board stores the in-situ threshold of the receiving container and the target weight threshold of the water injection corresponding to the water injection parameters. Based on the comparison between the weight signal and the threshold, the status of the reminder device is controlled, enabling parameterized prompts for the water injection volume. Simultaneously, the circuit board outputs a drain control signal based on the extraction time parameter. This drives the permanent magnet to move closer to or away from the channel to apply or remove the magnetic force to the sphere, thereby achieving timed opening and closing of the drain port. This allows the "water injection reminder—immersion timing—drain opening and closing" process to be established on a repeatable control logic based on threshold judgment and time triggering, reducing the uncertainty caused by manual judgment and multi-component opening and closing mechanisms, and improving process standardization and reliability.

[0028] The second objective of this invention is achieved as follows:

[0029] A smart tea extraction control method includes the following steps: S1. Acquiring a weight signal output from a weighing chassis and comparing the weight signal with a preset liquid receiving container in-situ threshold; when the weight signal reaches or exceeds the liquid receiving container in-situ threshold, entering the tea extraction workflow; S2. Reading extraction parameters recorded in an external carrier and / or receiving extraction parameters sent by an external terminal through a parameter acquisition device, and transmitting the extraction parameters to a circuit board, so that the circuit board stores the water injection target weight threshold corresponding to the extraction parameters, wherein the extraction parameters include at least water injection parameters and / or extraction time parameters; S3. During the water injection process, continuously acquiring the weight signal and comparing the weight signal with the preset liquid receiving container in-situ threshold. The target weight threshold for water injection is compared; when the weight signal reaches or exceeds the target weight threshold for water injection, the control reminder device is activated to prompt the water injection to stop; S4, when the preset extraction time corresponding to the extraction time parameter is reached, the circuit board outputs a positive drive signal to the micro motor to drive the micro motor to rotate forward, so that the permanent magnet approaches the channel, thereby applying a magnetic force to the sphere and moving the sphere to the second position to open the drain port, so that the extract is discharged through the tube and the drain port; S5, after the drain is completed, the circuit board outputs a reverse drive signal to the micro motor to drive the micro motor to rotate in reverse, so that the permanent magnet moves away from the channel, thereby releasing the magnetic force on the sphere and causing the sphere to return to the first position to close the drain port.

[0030] The tea extraction process is initiated by comparing the weight signal with the in-situ threshold of the liquid receiving container. The extraction parameters are combined to form a target weight threshold for water injection, and the comparison is continuously performed during the water injection process to drive the reminder device to prompt the water injection to stop. When the preset extraction time corresponding to the extraction time parameter is reached, the micro motor is controlled to move the permanent magnet close to the channel to attract the ball to open the drain port. After the liquid is drained, the permanent magnet moves away to release the magnetic force and cause the ball to return to its position to close the drain port. This can transform the key nodes from user experience operation to automatic execution according to threshold / time sequence, thereby improving the consistency and repeatability of water injection volume and liquid drainage timing control, and reducing the complexity of operation.

[0031] The beneficial effects of this invention are as follows:

[0032] (1) The controllable opening and closing of the drain port is achieved by the magnetic component and the movable ball, and the timing is controlled by the control component, which can reduce the dependence on manual opening and closing and improve the stability of the timing control of liquid discharge and the consistency of extraction.

[0033] (2) The upper and lower cups are clamped together to form a detachable extraction cup structure, which facilitates the disassembly and cleaning of the inside of the cup and related parts of the liquid outlet channel, thus improving the problem of inconvenient cleaning and easy residue in the existing integrated extraction cup.

[0034] (3) By configuring an elastic flow limiting device and setting a splash-proof flow limiting channel at the drain outlet, the outflow velocity is buffered and limited, reducing the probability of splashing due to excessively fast outflow and improving the user experience.

[0035] (4) Through the weighing detection and reminder device, and in conjunction with the acquisition of external extraction parameters, the circuit board can judge the real-time weight signal based on the preset in-situ threshold and the target weight threshold for water injection, and issue a timely reminder when the liquid receiving container is not placed or when the water injection reaches the target amount; at the same time, the circuit board can also perform timed control based on the extraction time parameter, and automatically output the liquid discharge control signal to control the opening and closing of the liquid outlet after the set soaking time is reached. Thus, the water injection reminder and liquid discharge timing can be stably executed according to the preset parameters, reducing the deviation caused by the user's reliance on visual inspection or experience operation, and improving the repeatability and reliability of the preparation process.

[0054] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0055] Combination Figures 1 to 18 As shown, this embodiment provides an extraction machine, which includes a main unit 1 and an extraction cup 2.

[0056] In this embodiment, the host 1 includes a base 11, a support 12, and a control component. The support 12 is disposed above the base 11, forming a liquid receiving container placement area 122 between the support 12 and the base 11 for placing the liquid receiving container 3. The support 12 has a channel 121 communicating with the liquid receiving container placement area 122 to accommodate the tube 25 of the extraction cup 2 and to ensure that the drain port 251 faces the liquid receiving container placement area 122. To achieve unmanned, controllable opening and closing of the drain port 251, a magnetic component is provided on the outside of the channel 121 of the support 12. The magnetic component is used to apply a magnetic force to the sphere 26 inside the extraction cup 2. The control component is used to control the magnetic force application state of the magnetic component to realize the opening and closing of the drain port 251.

[0057] Preferably, the magnetic component includes a permanent magnet 141 and a drive mechanism for driving the permanent magnet 141 closer to or further away from the channel 121; the drive mechanism includes a reversible micro motor 1421 and a transmission component 1422, the output end of the micro motor 1421 is connected to the transmission component 1422, and the transmission component 1422 is used to drive the permanent magnet 141 closer to or further away from the channel 121, thereby changing the relative position of the permanent magnet 141 and the channel 121 to apply or release the magnetic force on the sphere 26.

[0058] The control component is housed within the support 12. The control component includes a circuit board 131 and a switch. The switch is used to manually control the magnetic component's operation. The circuit board 131 has a timing control unit, which controls the magnetic component to open the drain port 251 when a preset soaking time is reached. This reduces the timing difference caused by user-timed operation versus manual opening and closing, improving the repeatability of the draining action. More preferably, the positive and / or reverse drive signals output by the circuit board 131 to the micro motor 1421 are drive pulses of a preset duration to ensure stable and consistent displacement of the permanent magnet 141 and reduce the continuous operating time of the micro motor 1421, thereby reducing energy consumption and heat generation.

[0059] In this embodiment, the base 11 includes a weighing chassis 15, which is used to detect the weight applied to the weighing chassis 15 and output a weight signal to the circuit board 131. Preferably, the weighing chassis 15 includes a support plate 151, a weighing sensor 152, and a base plate 153. One end of the weighing sensor 152 is connected to the support plate 151, and the other end is connected to the base plate 153. The main unit 1 also includes at least one support rod 16. The lower end of the support rod 16 is connected to the support plate 151 of the weighing chassis 15, and the upper end of the support rod 16 is connected to the support seat 12 to form a more stable force transmission structure. The support rod 16, the support seat 12, and the weighing chassis 15 form the liquid receiving container placement area 122, so that the weight signal of the liquid receiving container 3 can be stably acquired by the weighing chassis 15. Preferably, the channel 121 is aligned with the center of the support plate 151 to reduce the influence of the off-center load of the liquid receiving container 3 on the output of the weighing sensor 152 and improve the accuracy of the weight signal.

[0060] The main unit 1 also includes a reminder device, which is electrically connected to the circuit board 131. The circuit board 131 is used to control the operation of the reminder device according to the weight signal. The reminder device includes a light-emitting unit 200 and a sound-emitting unit. The light-emitting unit 200 is used to emit light of a preset color, and the sound-emitting unit is used to output prompt sounds, voice information and / or music signals to provide users with prompt feedback on water volume or process status.

[0061] To facilitate user triggering and improve triggering reliability, the host 1 may also be equipped with a button assembly 18, which includes an insulating component 181, a plated button 182, and a spring 183. The support rod 16 is a plated support rod and has a mounting hole 161. The insulating component 181 is disposed in the mounting hole 161 and has a button through hole 1811. The plated button 182 includes a button head 1821 and a connecting foot 1822. The connecting foot 1822 passes through the button through hole 1811 and is connected to the support 12. The button head 1821 is located in the mounting hole 1611. 1. On the outside; the insulating part 181 is located between the plating support rod and the plating button 182 to make them electrically insulated from each other; the switch is a touch switch, and the spring 183 is set in the cavity surrounded by the plating button 182. One end of the spring 183 abuts against the button head 1821, and the other end abuts against and is electrically connected to the sensing end of the touch switch, so that the plating button 182 is electrically connected to the sensing end through the spring 183, thereby making the touch trigger path more concentrated in the area of ​​the plating button 182, reducing the probability of false triggering caused by the user touching the support rod 16, and improving the triggering stability.

[0062] In this embodiment, the host 1 is equipped with a parameter acquisition device, which is electrically connected to the circuit board 131. The parameter acquisition device is used to read the extraction parameters recorded in an external carrier (not shown) and / or receive the extraction parameters sent by an external terminal (not shown), and transmit the read or received extraction parameters to the circuit board 131. The extraction parameters include at least water injection parameters and / or extraction time parameters. Preferably, the parameter acquisition device includes an NFC module, a Bluetooth communication module, and / or a wireless network communication module. The circuit board 131 stores a liquid receiving container in-situ threshold and a water injection target weight threshold corresponding to the water injection parameters. The circuit board 131 is used to acquire a weight signal and control the working state of the reminder device based on the comparison result of the weight signal with the liquid receiving container in-situ threshold and the water injection target weight threshold. The circuit board 131 is also used to output a drain control signal based on the extraction time parameter to control the drive mechanism to move the permanent magnet 141 closer to or further away from the channel 121, thereby controlling the magnetic force of the magnetic component on the sphere 26 to open or close the drain port 251.

[0063] In this embodiment, the extraction cup 2 includes a cup body 21, which comprises an upper cup body 211 and a lower cup body 212. The top of the upper cup body 211 is open, and a locking channel 2111 is provided at the lower end of the upper cup body 211. Preferably, the cross-sectional dimension of the locking channel 2111 gradually decreases along the insertion direction of the lower cup body 212. The top of the lower cup body 212 is open, and the shape of the upper end of the lower cup body 212 matches the locking channel 2111. The outer diameter of the upper end of the lower cup body 212 is smaller than the inlet diameter of the locking channel 2111 and larger than the outlet diameter of the locking channel 2111, so that the lower cup body 212 can be inserted into the upper cup body 211 and locked in the locking channel 2111. The lower cup body 212 is inserted into the upper cup body 211 from the open top and locked in place by the locking channel 2111, thereby assembling the cup body 21. The extraction cup 2 is detachable due to the locking assembly structure of the upper cup 211 and the lower cup 212, facilitating cleaning and maintenance of the interior of the cup 21 and the liquid outlet channel. To improve the sealing reliability after assembly, the extraction cup 2 also includes a sealing ring 22. The upper outer wall of the lower cup 212 is provided with a locking groove 2121 for accommodating the sealing ring 22. The sealing ring 22 is fitted and confined within the locking groove 2121. When the upper end of the lower cup 212 is locked in the locking channel 2111, the sealing ring 22 abuts against the inner wall of the locking channel 2111 and the upper outer wall of the lower cup 212, respectively, to seal the gap between the inner wall of the locking channel 2111 and the upper end of the lower cup 212. Preferably, the lower cup 212 is a plastic lower cup 212 to balance molding and assembly convenience.

[0064] To achieve filtration and separation, the extraction cup 2 may also include a filter screen 23, which is disposed inside the cup body 21 and above the tube body 25, preferably at the top opening of the lower cup body 212; the extraction cup 2 may also include a cup lid 24, which is detachably disposed at the top opening of the upper cup body 211 to close the cup body 21.

[0065] In this embodiment, the bottom of the lower cup body 212 is provided with a tube 25 that cooperates with the channel 121 and communicates with the cup body 21. The lower end of the tube 25 is provided with a drain port 251. Inside the tube 25 is a ball 26 that can move within the tube 25 and can be attracted by magnetic force. The diameter of the drain port 251 is smaller than the diameter of the ball 26. When the ball 26 is in the first position, it abuts against the lower end of the tube 25 to close the drain port 251. When the ball 26 is in the second position, it moves away from the drain port 251 to open the drain port 251. In use, the cup body 21 is placed on the support 12 and the tube body 25 is inserted into the channel 121, with the drain port 251 facing the liquid receiving container placement area 122. When the permanent magnet 141 approaches the channel 121 under the drive of the drive mechanism, the permanent magnet 141 applies a magnetic force to the ball 26, causing the ball 26 to move from the first position to the second position, thereby opening the drain port 251 and allowing the extract to be discharged. When the permanent magnet 141 moves away from the channel 121 under the drive of the drive mechanism, the magnetic force on the ball 26 is released, and the ball 26 returns to the first position under the action of gravity to close the drain port 251 again, thereby realizing the controllable opening and closing of the liquid outlet and reducing the dependence on manual timing and manual opening and closing.

[0066] In this embodiment, to reduce the instantaneous flow rate during the drainage stage and minimize splashing, the extractor further includes an elastic flow restrictor 27. The elastic flow restrictor 27 is located at the drainage port 251 and connected to the lower cup body 212. The elastic flow restrictor 27 has a splash-proof flow restricting channel 273 and a connecting section 272. The connecting section 272 is inserted into the drainage port 251 to connect the elastic flow restrictor 27 to the lower cup body 212, and the splash-proof flow restricting channel 273 communicates with the drainage port 251. The splash-proof flow restricting channel 273 is used to generate flow damping for the liquid discharged through the drainage port 251.

[0067] Preferably, the elastic flow restrictor 27 includes a main body section 271 and a plug-in section 272. The top of the plug-in section 272 is provided with an arc-shaped guide edge 2721, and the top center of the plug-in section 272 is provided with a downward-facing recessed ball seat cavity 2722. The splash-proof flow restrictor channel 273 passes through the plug-in section 272 and the main body section 271, and the inlet of the splash-proof flow restrictor channel 273 opens into the ball seat cavity 2722. More preferably, the cross-sectional size of the splash-proof flow restrictor channel 273 gradually decreases along the liquid flow direction, and the inlet diameter is larger than the outlet diameter, so as to form a more obvious flow restriction and buffering effect. The outer diameter of the plug-in section 272 is smaller than the outer diameter of the main body section 271, and the connection between the plug-in section 272 and the main body section 271 is provided with an annular groove 2723 to achieve a snap-fit ​​fit with external components. The elastic flow restrictor 27 is preferably made of silicone rubber material to facilitate plug-in assembly and to take into account both sealing and rebound. When the sphere 26 moves upward to the second position under the action of magnetic force, the sphere 26 moves upward relative to the ball seat cavity 2722 and is still located above the ball seat cavity 2722, so that an annular gap (not shown) is formed between the sphere 26 and the ball seat cavity 2722. The annular gap is connected to the inlet of the anti-splash flow limiting channel 273, thereby forming a flow channel connected to the anti-splash flow limiting channel 273, so that the extract liquid is smoothly discharged through the anti-splash flow limiting channel 273 and splashing is reduced.

[0068] Preferably, the main unit 1 further includes a waterproof ambient light 300, which is disposed at the bottom of the support 12 and arranged around the periphery of the channel 121. The waterproof ambient light 300 is electrically connected to and controlled by the circuit board 131; when the waterproof ambient light 300 is activated, the light emitted by it illuminates the liquid receiving container placement area 122, providing intuitive visual prompts during the water filling, soaking timer, and liquid draining stages, and assisting users in observing the position of the liquid receiving container 3 and the liquid landing point in low-light environments, thereby improving the interactive experience and overall aesthetics.

[0069] How to use the extractor: The user places the liquid receiving container 3 in the liquid receiving container placement area 122 of the main unit 1. It is preferable to place the liquid receiving container 3 in the center and keep a gap between it and the support 12 to avoid contact with the support rod 16 and other structures, which may introduce weighing deviation. When the weighing base 15 detects that the weight has reached the liquid receiving container in place threshold, the circuit board 131 enters the extraction process control state. Subsequently, the user places the raw material to be extracted into the extraction cup 2 (with filter 23 if necessary), places the extraction cup 2 on the support 12, inserts the tube 25 into the channel 121 of the support 12 with the drain port 251 facing the receiving container 3; after the parameter acquisition device reads or receives the extraction parameters, the user injects water according to the water injection parameters. During the water injection process, the circuit board 131 continuously collects the weight signal output by the weighing sensor 152 and compares it with the target weight threshold. When the target threshold is reached, the control reminder device provides a light / sound prompt to stop the water injection; then the soaking timer stage begins. After the preset soaking time is reached, the circuit board 131 controls the drive mechanism to bring the permanent magnet 141 close to the channel 121, applying magnetic force to the ball 26 to make the ball 26 leave the drain port 251 to drain the liquid; after the liquid is drained, the circuit board 131 controls the drive mechanism to move the permanent magnet 141 away from the channel 121 to release the magnetic force, allowing the ball 26 to return to the drain port 251 under the action of gravity to achieve resealing. The user can then remove the receiving container 3 to complete the beverage preparation.

[0070] Cleaning method for the extraction cup: After extraction is completed and the drain port 251 is confirmed to be closed, remove the extraction cup 2 from the support 12. For structures where the upper cup body 211 and the lower cup body 212 are clamped together, the user can remove the lower cup body 212 from the upper cup body 211 and disassemble and clean the filter screen 23, cup cover 24, sealing ring 22, and elastic flow restrictor 27 respectively. During cleaning, it is preferable to first rinse the inner wall of the cup body 21, the filter screen 23, and the tube body 25, and then brush the inner wall of the tube body 25, the area near the drain port 251, and the contact area of ​​the ball 26. For the elastic flow restrictor 27, it is preferable to focus on cleaning the ball seat cavity 2722 and the inlet and outlet of the splash-proof flow restrictor channel 273 to prevent residual blockage from affecting the subsequent flow restrictor effect. During reassembly, confirm that the sealing ring 22 is correctly embedded in the locking groove 2121 and is not flipped, that the lower cup body 212 and the locking channel 2111 are locked in place, and that the elastic flow limiting element 27 plug section 272 is reliably inserted into the drain port 251, so as to ensure the stability of sealing and drain control.

[0071] Water flow buffering and anti-splashing method: An elastic flow limiting component 27 is installed at the drain port 251, with its plug section 272 inserted into the drain port 251 and reliably engaged with the drain port 251, so that the anti-splash flow limiting channel 273 is connected to the drain port 251; when the circuit board 131 controls the permanent magnet 141 to approach the channel 121 and drives the ball 26 to move upward to open the drain port 251, the extract first enters the anti-splash flow limiting channel 273 through the flow gap formed by the ball 26 and the ball seat cavity 2722, and then is discharged through the flow limiting path with gradually decreasing channel cross-section, thereby damping the liquid flow and reducing the instantaneous flow velocity, reducing splashing caused by direct discharge; at the same time, it is preferable to align the opening of the liquid receiving container 3 with the bottom of the drain port 251 to further stabilize the landing point and reduce the probability of splashing.

[0072] Methods to prevent accidental triggering of the touch switch: Touch triggering is preferably limited to touch operation of the plated button 182. The plated button 182 and the plated support rod are electrically insulated from each other by the insulating component 181, structurally reducing the probability of "triggering upon user contact with the support rod 16". Simultaneously, the plated button 182 is electrically connected to the sensing end of the switch via the spring 183, making the touch signal coupling path more concentrated in the area of ​​the plated button 182. This reduces accidental triggering caused by moisture, accidental human contact with non-button areas, or environmental interference, improving the stability and reliability of touch control.

[0073] The permanent magnet employs an energy-saving method controlled by a micro-motor: Circuit board 131 preferably controls micro-motor 1421 with drive pulses of preset duration. When the drain port 251 needs to be opened, a positive drive pulse is output to drive micro-motor 1421 to rotate forward, causing permanent magnet 141 to approach channel 121 under the drive of transmission component 1422 and complete the attraction displacement of sphere 26. When the drain port 251 needs to be closed, a reverse drive pulse is output to drive micro-motor 1421 to rotate in reverse, causing permanent magnet 141 to move away from channel 121 to release the magnetic force and cause sphere 26 to return to its closed position. Since the permanent magnet 141 does not need to be continuously powered to generate magnetic force, and micro-motor 1421 only works briefly during the displacement switching phase, it can reduce continuous energy consumption and heat generation while ensuring opening and closing reliability, improve overall energy efficiency, and contribute to long-term operational stability.

[0074] Accurate weighing method: The channel 121 of the support 12 is preferably aligned with the center of the bearing plate 151 of the weighing chassis 15, so that the liquid discharge point is as consistent as possible with the placement center of the liquid receiving container 3, thereby reducing the influence of off-center load on the output of the weighing sensor 152 and improving the linearity and repeatability of the weight signal. At the same time, the user preferably places the bottom of the liquid receiving container 3 completely on the effective bearing area of ​​the weighing chassis 15 and centered it, avoiding lateral contact between the liquid receiving container 3 and the support rod 16, support 12, etc., which would cause component forces to introduce weighing errors. During the water filling stage, keeping the main unit 1 on a stable and level platform and avoiding touching or moving the main unit 1 can further ensure the accuracy of the weight threshold comparison, making the water filling prompt and subsequent liquid discharge timing control more reliable.

[0075] This embodiment provides an intelligent tea extraction control method using the above-mentioned extraction machine, including the following steps: S1, acquiring the weight signal output by the weighing chassis 15 and comparing the weight signal with a preset liquid receiving container in-situ threshold; when the weight signal reaches or exceeds the liquid receiving container in-situ threshold, the tea extraction process begins; S2, reading the extraction parameters recorded in the external carrier and / or receiving the extraction parameters sent by the external terminal through the parameter acquisition device, and transmitting the extraction parameters to the circuit board 131, so that the circuit board 131 stores the water injection target weight threshold corresponding to the extraction parameters, wherein the extraction parameters include at least water injection parameters and / or extraction time parameters; S3, continuously acquiring the weight signal during the water injection process and comparing the weight signal with the water injection target weight threshold; when the weight signal reaches or exceeds the liquid receiving container in-situ threshold, the tea extraction process begins; S4, acquiring the weight signal output by the weighing chassis 15 and comparing the weight signal with a preset liquid receiving container in-situ threshold; when the weight signal reaches or exceeds the liquid receiving container in-situ threshold, the tea extraction process begins; S5, reading the extraction parameters recorded in the external carrier and / or receiving the extraction parameters sent by the external terminal, and transmitting the extraction parameters to the circuit board 131, so that the circuit board 131 stores the water injection target weight threshold corresponding to the extraction parameters, wherein the extraction parameters include at least water injection parameters and / or extraction time parameters; S6, continuously acquiring the weight signal during the water injection process and comparing the weight signal with the water injection target weight threshold; when the weight signal reaches or exceeds the liquid receiving container in-situ threshold, the tea extraction process begins; when the weight signal reaches or exceeds the liquid receiving container in-situ threshold, the tea extraction process begins; S7, acquiring the weight signal output by the weighing chassis 15 and comparing the weight signal with a preset liquid receiving container in-situ threshold, the tea extraction process begins; S8, acquiring the weight signal with a preset liquid receiving container in-situ threshold, and comparing the weight signal with a preset liquid receiving container in-situ threshold, the tea extraction process begins; S9, acquiring the weight signal with a preset liquid receiving container in When the target weight threshold for water injection is exceeded, circuit board 131 controls the reminder device to activate and prompt the user to stop water injection; S4, when the preset extraction time corresponding to the extraction time parameter is reached, circuit board 131 outputs a positive drive signal to micro motor 1421 to drive micro motor 1421 to rotate forward, causing permanent magnet 141 to approach channel 121, thereby applying magnetic force to sphere 26 and moving sphere 26 to the second position to open drain port 251, allowing the extract to be discharged through tube 25 and drain port 251; S5, after draining is completed, circuit board 131 outputs a reverse drive signal to micro motor 1421 to drive micro motor 1421 to rotate in reverse, causing permanent magnet 141 to move away from channel 121, thereby releasing the magnetic force on sphere 26 and allowing sphere 26 to return to the first position to close drain port 251. Through the above control process based on weight threshold and time parameter, the water injection volume prompt and draining timing control can be executed according to preset parameters, reducing deviations caused by user visual inspection or experience operation, and improving the standardization of the extraction process and the repeatability of preparation results.

[0076] To further enhance the user experience, users' mobile phones can connect wirelessly to the main unit. The main unit receives audio signals from the phone via Bluetooth, Wi-Fi, or other wireless communication modules. The main unit's speaker then plays music based on the received audio signal, allowing users to enjoy the relaxation and pleasure of music while brewing tea. This feature not only adds enjoyment to the usage scenario but also provides users with a richer entertainment experience, making tea preparation not only a sensory pleasure but also an auditory one.

[0077] In other embodiments, the magnetic component is an electromagnet, which is located near the channel 121. The circuit board 131 is used to control the electromagnet to be energized or de-energized, so as to change the magnetic force state of the electromagnet on the sphere 26.

[0078] In other embodiments, to effectively reduce liquid flow rate fluctuations and splashing, the inlet portion of the splash-proof flow-limiting channel 273 has a curved structure to guide the liquid flow in a specific direction. Furthermore, the outlet portion of the splash-proof flow-limiting channel 273 has a gradient shape, gradually increasing the outlet diameter, thereby further reducing the instantaneous flow rate and splashing. The cross-sectional shape of the splash-proof flow-limiting channel 273 is trapezoidal to provide greater flow resistance and ensure a more stable flow rate. The outer wall of the insertion section has anti-slip textures to increase the contact area with the drain port, thereby enhancing insertion stability and improving sealing. The splash-proof flow-limiting channel 273 has a uniform flow rate attenuation zone between the inlet and outlet, achieving a gradual reduction in flow rate through a multi-layered structural design, ensuring smoother liquid flow and reducing splashing. The inlet diameter of the splash-proof flow-limiting channel 273 is larger than the outlet diameter, creating a significant flow restriction effect when the liquid flows through the channel, effectively reducing the instantaneous flow rate at the outlet and preventing liquid from splashing into the surrounding area.

[0079] In other embodiments, to improve the corrosion resistance and stain resistance of the splash-proof flow-limiting channel 273 under repeated action of high-temperature water, tea polyphenols / coffee acidic components and cleaning agents, a corrosion-resistant coating is provided on the inner surface of the splash-proof flow-limiting channel 273.

[0080] The corrosion-resistant coating may be a multi-layer structure, preferably comprising an adhesion underlayer, a barrier intermediate layer, and a hydrophobic and oleophobic surface layer formed sequentially. The adhesion underlayer is used to improve the adhesion between the coating and the elastic flow restrictor 27 (e.g., silicone rubber), and may be a silane coupling agent underlayer (e.g., an amino / epoxy silane system) or a surface-modified layer formed by plasma activation. The barrier intermediate layer is used to form a dense barrier film to improve resistance to hydrolysis and chemical corrosion, and is preferably a parylene coating or a sol-gel silica coating. The hydrophobic and oleophobic surface layer is used to reduce the surface energy of the inner wall and reduce liquid adhesion and residue, and is preferably a fluoropolymer coating (e.g., a thin fluoropolymer layer) or a fluorosilane self-assembled coating. More preferably, the total thickness of the corrosion-resistant coating is 1 μm to 30 μm, wherein the thickness of the barrier intermediate layer is 1 μm to 20 μm, and the thickness of the hydrophobic and oleophobic surface layer is 0.05 μm to 2 μm. This achieves a comprehensive effect of corrosion resistance, easy cleaning, and stable flow throttling without significantly changing the channel size of the splash-proof flow-limiting channel 273. Through the above configuration, the changes in channel roughness caused by corrosion or contamination of the inner wall can be reduced, thereby reducing flow rate fluctuations and improving long-term consistency.

[0081] In other embodiments, to further reduce the pulsating and impulsive flow velocities of the liquid within the splash-proof flow-limiting channel 273, flow-guiding baffles (not shown) are provided within the splash-proof flow-limiting channel 273. These baffles are arranged in a multi-stage throttling structure at intervals along the liquid flow direction. Preferably, the flow-guiding baffles are sheet-like or rib-like structures integrally formed with the elastic flow-limiting element 27. They divide the flow channel within the channel cross-section to form at least two series-connected throttling chambers, causing graded pressure drops and kinetic energy dissipation as the liquid passes through each stage of the baffles, thereby resulting in a more stable flow velocity at the outlet. More preferably, each flow guide baffle is provided with a through hole, which is staggered circumferentially between adjacent baffles, so that the liquid forms a tortuous flow path (S-shaped or zigzag flow path) in the channel to increase flow resistance and suppress straight flow. The through hole can be circular, elliptical, or slit-shaped, wherein the long axis of the slit-shaped through hole forms an angle of 10° to 60° with the mainstream direction, which is used to guide the liquid to rotate or deflect along the wall, further reducing the instantaneous flow velocity peak. More preferably, the edges of the flow guide baffle can be provided with rounded transitions or arc-shaped flow guide surfaces to avoid the formation of obvious backflow dead angles that lead to residue accumulation; and micro-protrusions or fine textures can be provided on the surface of the baffle to form additional disturbance energy dissipation and reduce the tendency of liquid agglomeration and jetting, thereby further reducing splashing.
