Description

Technical Field

[0001] This application relates to the field of beverage preparation technology, and in particular to a powder pressing device for beverage preparation equipment. Background Technology

[0002] Tampering is a crucial step in coffee preparation, requiring the ground coffee powder to be pressed before brewing. This step significantly impacts the flavor of the final coffee. Currently, coffee tamping is generally achieved manually or automatically. While automatic tamping machines can perform basic tamping, their tamping pressure control is inaccurate, lacking precise and real-time monitoring. This uncertainty in tamping pressure severely affects the taste of the brewed coffee, resulting in a poor user experience. For example, Chinese patent CN113842042A discloses a coffee tamper comprising a tamping body, a handle, and a cone-shaped part. The lower part of the handle connects to the cone-shaped part, jointly defining the internal filling cavity of the tamping body. Specifically, the coffee tamper is operated by holding the handle, causing the cone-shaped part to press the coffee powder. It is evident that this coffee tamper uses a direct-fall tamping method to tamp the coffee powder. This tamping method leads to inaccurate control of tamping force and makes it impossible to accurately and in real-time detect the tamping force, thus affecting the taste of the prepared coffee liquid. Utility Model Content

[0003] To address the aforementioned technical problems in the prior art, this application provides a powder pressing device for beverage preparation equipment. This device can detect the reaction force exerted by powdered ingredients on the pressing component in real time through a first pressure detection component, thereby achieving accurate and real-time detection of the pressing force. This allows the pressing force to be adjusted to meet the user's needs, thus producing a beverage with a taste that meets the user's requirements.

[0004] This application provides a powder pressing device for beverage preparation equipment, characterized in that it includes:

[0005] A powder receiving assembly includes a funnel assembly and a powder receiving cavity disposed above the funnel assembly, the funnel assembly having a receiving cavity for receiving powdered food from the powder receiving cavity;

[0006] A movable powder pressing assembly is at least partially movably disposed within the powder receiving cavity to perform a lifting and lowering movement relative to or away from the funnel assembly within the powder receiving cavity. The movable powder pressing assembly includes a driving member and a powder pressing member disposed within the receiving cavity. The driving member drives the powder pressing member to rotate and press powder within the receiving cavity when powder is falling from the powder receiving cavity into the receiving cavity. The driving member is connected to a trigger member.

[0007] A first pressure detection component is configured corresponding to the trigger. When the trigger moves away from the funnel assembly, it acts on the first pressure detection component, causing it to generate first pressure feedback information to detect the pressure exerted by the powdered ingredients on the pressing component in real time. This structure enables precise and real-time detection of the pressing force, allowing the pressing force to be adjusted to meet user needs and produce beverages with the desired taste.

[0008] In some embodiments, the powder pressing device further includes a control component electrically connected to the first pressure detection component. The control component receives the first pressure feedback information sent by the first pressure detection component and, when the pressure value of the first pressure feedback information exceeds a first preset threshold, causes the powder receiving component to stop discharging powder into the receiving cavity. The above-described powder pressing device is simple to operate, reduces the skill requirements for the user, and helps ensure the consistency of the prepared beverage.

[0009] In some embodiments, the movable powder pressing assembly further includes a limiting member, a trigger member disposed on the limiting member, the limiting member being connected to the driving member, and the limiting member, the driving member, and the powder pressing member moving up and down synchronously within the powder receiving cavity, so that when the powder pressing member is subjected to the force of powdered food, the trigger member on the limiting member abuts against the first pressure detection component. Thus, by placing the trigger member on the limiting member and connecting the limiting member to the driving member, a stable connection between the trigger member and the driving member can be achieved.

[0010] In some embodiments, the powder pressing component includes a plurality of blades, the outer edge of which is formed with a groove. The movable powder pressing assembly further includes a powder scraper slidably disposed in the groove. The powder scraper is used to slide away from the blades when the blades rotate to abut against the inner wall of the receiving cavity, so as to thoroughly sweep the powder from the entire receiving cavity and prevent residual powdery ingredients from affecting the taste of the beverage.

[0011] In some embodiments, the outer side of the powder scraper is provided with a raised rib structure, which is used to abut against the inner wall of the receiving cavity. In this way, the raised rib structure on the outer side of the powder scraper can achieve a better powder-scraping effect and prevent excessive powdery food residue from remaining on the cavity wall.

[0012] In some embodiments, the movable powder pressing assembly further includes a connector, the upper end of which is connected to the drive member, and the lower end of which is detachably connected to the powder pressing member. The limiting member is located above the connector. Thus, the drive member can drive the powder pressing member to rotate stably via the connector.

[0013] In some embodiments, the lower end of the connector is provided with a first magnetic element, and the powder pressing component is provided with a second magnetic element. The first and second magnetic elements are magnetically attracted to each other, so that the powder pressing component is connected to the lower end of the connector. In this way, a stable and detachable connection between the connector and the powder pressing component can be achieved through the magnetic attraction of the first and second magnetic elements.

[0014] In some embodiments, the powder receiving assembly further includes a base disposed above the powder receiving cavity, the output shaft of the drive member extending through the base into the powder receiving cavity, and a limiting rod disposed parallel to the trigger member on the limiting member, the end of the limiting rod away from the limiting member being used to abut against the base to limit the displacement of the limiting member. Thus, the upward displacement of the limiting member can be limited by the limiting rod on the limiting member stably abutting against the base.

[0015] In some embodiments, the substrate is provided with a second pressure detection component corresponding to the limiting rod. When the limiting rod moves away from the funnel assembly, it acts on the second pressure detection component, causing the second pressure detection component to generate second pressure feedback information. Thus, based on the detected first and second pressure feedback information, the real-time performance and accuracy of detecting the pressure applied by the powdered food material to the pressing component can be ensured.

[0016] In some embodiments, the powder pressing device further includes a grinding component electrically connected to the control component. The powder outlet of the grinding component is connected to the powder receiving chamber. The control component is further configured to control the grinding component to stop working when the pressure value of the first pressure feedback information exceeds a first preset threshold. Thus, when the pressure value of the first pressure feedback information exceeds the first preset threshold, the grinding component can be controlled to stop working in a timely manner, thereby stopping the powder receiving component from discharging powder into the receiving chamber, ensuring that the receiving chamber contains a suitable amount of powder, and guaranteeing the brewing effect.

[0017] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: This application achieves uniform compaction of powdered ingredients in the accommodating cavity by having at least a portion of the movable powder pressing component move relatively close to or away from the funnel component within the powder receiving cavity, and by having the powder pressing component rotate and press the powder within the accommodating cavity when the powder is falling from the powder receiving cavity into the accommodating cavity. This also enables simultaneous powder feeding and pressing, improving the pressing effect. Furthermore, the triggering component connected to the driving component can trigger the first pressure detection component, allowing the first pressure detection component to detect the reaction force exerted by the powdered ingredients on the powder pressing component in real time after being subjected to force. This achieves accurate and real-time detection of the pressing force, allowing the pressing force to be adjusted to meet the user's needs, thereby preparing a beverage with a taste that meets the user's requirements. This achieves the purpose of selecting different pressing forces to match the amount and fineness of the powder, resulting in a beverage with a better taste. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This application provides a powder pressing device for beverage preparation equipment. For example... Figures 1 to 4 As shown, the powder pressing device includes a powder receiving assembly 1, a movable powder pressing assembly 2, and a first pressure detection assembly 7. The powder receiving assembly 1 includes a funnel assembly 11 and a powder receiving cavity 12 disposed above the funnel assembly 11. The funnel assembly 11 has a receiving cavity 13 for receiving powdered food from the receiving cavity 12. At least a portion of the movable powder pressing assembly 2 is movably disposed within the receiving cavity 12 to perform a lifting and lowering motion relative to or away from the funnel assembly 11 within the receiving cavity 12. The movable powder pressing assembly 2 includes a driving member 21 and a powder pressing member 3 disposed within the receiving cavity 13. The driving member 21 drives the powder pressing member 3 to rotate and press powder within the receiving cavity 13 when powder falls from the receiving cavity 12 into the receiving cavity 13. The driving member 21 is connected to a trigger member 4. The first pressure detection assembly 7 is disposed corresponding to the trigger member 4. When the trigger member 4 moves in a direction away from the funnel assembly 11, it acts on the first pressure detection assembly 7, causing the first pressure detection assembly 7 to generate first pressure feedback information to detect the pressure exerted by the powdered food on the powder pressing member 3 in real time.

[0030] The powdered ingredients in the powder receiving chamber 12 can come from the grinding component 8. The grinding component 8 grinds the beans to form powdered ingredients, such as grinding coffee beans to form coffee powder. The powdered ingredients are then discharged through the powder receiving chamber 12 into the receiving chamber 13 of the funnel component 11.

[0031] The powder receiving cavity 12 can be formed on a powder receiving member, which can be connected to the upper opening of the funnel assembly 11. The powder receiving cavity 12 can be constructed as a cavity with openings at both the upper and lower ends, so that the drive member 21 of the movable powder pressing assembly 2 can extend into the powder receiving cavity 12 through the upper opening of the powder receiving cavity 12 and pass through the powder receiving cavity 12 to connect with the powder pressing member 3 located in the receiving cavity 13.

[0032] The aforementioned funnel assembly 11 may include a powder bowl, which forms the aforementioned receiving cavity 13. Powdered ingredients are placed inside the powder bowl, and the powder pressing component 3 is used to rotatably press the powdered ingredients toward the bottom of the powder bowl.

[0033] As powder continuously falls from the receiving cavity 12 into the containing cavity 13 and the pressing component 3 rotates and presses the powder within the containing cavity 13, the pressing component 3 will be subjected to a reaction force exerted by the powdered food. When the reaction force exceeds a certain threshold, the pressing component 3 and the driving component 21 will move synchronously away from the funnel assembly 11, that is, the pressing component 3 and the driving component 21 will move upward synchronously. This causes the trigger component 4 connected to the driving component 21 to act on the first pressure detection component 7. The force exerted by the trigger component 4 on the first pressure detection component 7 can be understood as continuously increasing as the amount of powdered food in the containing cavity 13 increases. Therefore, the pressure exerted by the powdered food on the pressing component 3 can be detected in real time based on the first pressure feedback information generated by the first pressure detection component 7, thereby achieving precise control over the amount of powdered food in the containing cavity 13 and the pressing effect of the pressing component 3.

[0034] After the first pressure detection component 7 generates the first pressure feedback information, the user can control whether the powder receiving component 1 continues to dispense powder into the receiving cavity 13 according to actual needs. This can be achieved manually or automatically by the powder pressing device. For example, when the pressure value of the first pressure feedback information reaches the first pressure value, the user can manually control the powder receiving component 1 to stop dispensing powder into the receiving cavity 13, and can also manually control the drive component 21 to stop working, thus stopping both powder dispensing into the receiving cavity 13 and powder pressing within the receiving cavity 13. Alternatively, when the pressure value of the first pressure feedback information reaches the first pressure value, the powder pressing device can automatically control the powder receiving component 1 to stop dispensing powder into the receiving cavity 13 and control the drive component 21 to stop working, eliminating the need for manual operation and improving user convenience.

[0035] The fact that at least part of the movable powder pressing component 2 is movable within the powder receiving cavity 12 can be understood as the movable powder pressing component 2 being able to keep the powder pressing part 3 within the receiving cavity 13 under its own weight. As powder continuously falls from the receiving cavity 12 into the receiving cavity 13, and the reaction force exerted on the powder pressing part 3 by the powdered food gradually increases, the movable powder pressing component 2 will move upward as a whole to move away from the funnel component 11.

[0036] The lower surface of the aforementioned powder pressing component 3 can contact the powdered food surface inside the accommodating cavity 13 to achieve a better powder pressing effect.

[0037] The aforementioned first pressure detection component 7 can be a pressure detection device, specifically a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, etc. When the trigger 4 acts on the first pressure detection component 7, the surface of the first pressure detection component 7 will be pressed and will sense the change of the corresponding parameter. For example, the deformation of the piezoresistive pressure sensor will cause the resistance value to change, which will be converted into an electrical signal through the circuit, thereby realizing the real-time detection of the pressure applied to the trigger 4.

[0038] The aforementioned powder pressing device may include a display element, which is electrically connected to the first pressure detection component 7. It can display the first pressure feedback information generated by the first pressure detection component 7 in real time, so that the user can know the pressure applied by the powdered food to the powder pressing component 3. The pressure applied by the powdered food to the powder pressing component 3 can characterize the amount of powdered food in the accommodating cavity 13, and can also characterize the powder pressing state of the powder pressing component 3. The gradual increase of the pressure applied by the powdered food to the powder pressing component 3 can be understood as the amount of powdered food gradually increasing, and the powder pressing component 3 has compacted the powdered food.

[0039] This application achieves uniform compaction of powdered ingredients within the receiving cavity 13 by having at least a portion of the active powder pressing component 2 move relatively close to or away from the funnel component 11 within the powder receiving cavity 12, and by having the powder pressing component 3 rotate and press the powder within the receiving cavity 13 when powder is fed from the receiving cavity 12 to the receiving cavity 13. Furthermore, it enables simultaneous powder feeding and pressing, improving the pressing effect. The trigger component 4 connected to the drive component 21 can trigger the first pressure detection component 7, allowing it to detect the reaction force exerted by the powdered ingredients on the powder pressing component 3 in real time after being subjected to force. This achieves precise and real-time detection of the pressing force, enabling the pressing force to be adjusted to meet user needs, thus preparing beverages with the desired taste. It also allows for the selection of different pressing forces to match the amount and fineness of the powder, ultimately resulting in a beverage with a superior taste.

[0040] In some embodiments, the powder pressing device further includes a control component (not shown) electrically connected to the first pressure detection component 7. The control component is used to receive first pressure feedback information sent by the first pressure detection component 7, and to stop the powder receiving component 1 from discharging powder into the receiving cavity 13 when the pressure value of the first pressure feedback information exceeds a first preset threshold.

[0041] Thus, by controlling the powder receiving component, when the pressure value of the first pressure feedback information exceeds the first preset threshold, the powder receiving component 1 can be automatically controlled to stop dispensing powder into the receiving cavity 13, ensuring that the amount of powder in the receiving cavity 13 is appropriate, which is beneficial to ensuring the brewing effect of the beverage. The above-mentioned powder pressing device is simple to operate, which can reduce the requirements for the user's operating skills and help ensure the consistency of the prepared beverage.

[0042] The aforementioned control components are also used to stop the powder receiving component 1 from working when the pressure value of the first pressure feedback information exceeds the first preset threshold, so as to ensure that the amount of powder in the accommodating cavity 13 is appropriate while ensuring that the powder pressing component 3 presses the powder appropriately, thereby achieving a better powder pressing effect and further ensuring the brewing effect of the beverage.

[0043] The aforementioned first preset threshold can be set at the factory when the powder pressing device leaves the factory, or it can be set by the user according to their needs. The first preset threshold can be flexibly adjusted rather than fixed, so as to dynamically adjust the amount of powder in the accommodating cavity 13 to prepare a beverage that better meets the user's taste requirements, thereby increasing the flexibility of the powder pressing device.

[0044] It should be noted that the control components can be built using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0045] In some embodiments, the active powder pressing assembly 2 further includes a limiting member 5, a trigger member 4 is disposed on the limiting member 5, the limiting member 5 is connected to the driving member 21, and the limiting member 5 moves up and down synchronously with the driving member 21 and the powder pressing member 3 in the powder receiving cavity 12, so that after the powder pressing member 3 is subjected to the force of the powdered food, the trigger member 4 on the limiting member 5 abuts against the first pressure detection assembly 7.

[0046] Thus, by setting the trigger 4 on the limiting member 5 and connecting the limiting member 5 to the driving member 21, a stable connection between the trigger 4 and the driving member 21 can be achieved, and the trigger 4 moves upward synchronously with the driving member 21 and the powder pressing member 3 to trigger the first pressure detection component 7 upward.

[0047] The aforementioned limiting member 5 can be constructed as a plate, with the trigger member 4 disposed on the upper plate surface of the limiting member 5 and the powder pressing member 3 disposed below the lower plate surface of the limiting member 5. Furthermore, the limiting member 5 only performs lifting and lowering movements and does not rotate. Bearings or other components can be provided between the limiting member 5 and the powder pressing member 3 to reduce friction between the limiting member 5 and the rotating powder pressing member 3.

[0048] In some embodiments, such as Figures 4 to 7 As shown, the powder pressing component 3 includes multiple blades 31, and the outer edge of each blade 31 has a groove 32. The movable powder pressing assembly 2 also includes a powder scraper 6 slidably disposed within the groove 32. The powder scraper 6 is used to slide away from the blades 31 when the blades 31 rotate, so as to abut against the inner wall of the receiving cavity 13. (Specific details can be found in conjunction with...) Figure 6 and Figure 7 , Figure 6 The powder scraper 6 shown is in the first position close to the blade 31. Figure 7 The powder scraper 6 shown is in a second position away from the blade 31.

[0049] In this way, the powder scraper 6, which is slidably located in the groove 32 of the blade 31, can be used to thoroughly sweep the powder from the entire accommodating cavity 13, preventing residual powdery ingredients from affecting the taste of the beverage.

[0050] like Figures 4 to 7 As shown in the figure, the number of blades 31 shown is two for example only. This application does not specify the number of blades 31, as long as they can fully compress the powder.

[0051] The aforementioned powder scraper 6 can be provided in a one-to-one correspondence with the blade 31, or it can be provided on some of the blades 31, instead of providing the powder scraper 6 on every blade 31. This application does not make a specific limitation in this regard, as long as it can fully sweep the powder from the entire accommodating cavity 13.

[0052] A limiting block may be provided in the aforementioned chute 32. The limiting block is used to limit the displacement of the scraper 6 in the direction away from the blade 31, so as to prevent the scraper 6 from separating from the chute 32 and to ensure the connection stability of the scraper 6 and the blade 31.

[0053] The aforementioned powder scraper 6 can be evenly arranged around the output shaft of the drive unit 21 to achieve the purpose of uniform powder scraping.

[0054] A gap is formed between the aforementioned blade 31 and the cavity wall of the receiving cavity 13, preventing interference between the powder pressing component 3 and the receiving cavity 13 and facilitating the rotation of the powder pressing component 3 within the receiving cavity 13. The distance that the aforementioned powder scraper 6 slides away from the blade 31 is the size of the gap between the aforementioned blade 31 and the cavity wall of the receiving cavity 13, allowing it to directly contact the cavity wall of the receiving cavity 13 during rotation for effective powder sweeping.

[0055] In some embodiments, such as Figure 5 As shown, the outer side of the powder scraper 6 is provided with a rib structure 61, which is used to abut against the inner wall of the accommodating cavity 13.

[0056] In this way, the convex rib structure 61 on the outer side of the powder scraper 6 can achieve a better powder-scraping effect, avoiding excessive residue of powdery ingredients on the cavity wall of the accommodating cavity 13.

[0057] The aforementioned rib structure 61 can be constructed as a long strip, with its length direction being the same as the axial direction of the output shaft of the drive member 21, so as to have more contact with the cavity wall of the accommodating cavity 13.

[0058] The aforementioned rib structure 61 can be made of an elastic material so that it can rotate smoothly and make more contact with the cavity wall of the receiving cavity 13 through its own deformation in conjunction with the rotation of the powder pressing component 3, thereby achieving a better powder sweeping effect.

[0059] In some embodiments, such as Figures 1 to 4As shown, the active powder pressing assembly 2 also includes a connector 22. The upper end of the connector 22 is connected to the drive component 21, and the lower end of the connector 22 is detachably connected to the powder pressing component 3. The limiting component 5 is located above the connector 22.

[0060] Thus, the driving component 21 can drive the powder pressing component 3 to rotate stably through the connecting component 22, and the limiting component 5 is located above the connecting component 22, which can avoid interference between the limiting component 5 and the rotating connecting component 22 and the powder pressing component 3, so that the limiting component 5 can move up and down smoothly in the powder receiving cavity 12.

[0061] The lower end of the aforementioned connector 22 is detachably connected to the powder pressing component 3, specifically by means of snap-fit ​​connection, threaded connection, plug-in connection, magnetic connection, etc.

[0062] The aforementioned connector 22 can be specifically constructed as a connecting shaft, with its two ends connected to the drive component 21 and the powder pressing component 3, respectively.

[0063] In some embodiments, the lower end of the connector 22 is provided with a first magnetic element (not shown in the figure), and the powder pressing component 3 is provided with a second magnetic element (not shown in the figure). The first magnetic element and the second magnetic element are magnetically attracted to each other, so that the powder pressing component 3 is connected to the lower end of the connector 22.

[0064] In this way, the first and second magnetic components can be magnetically attracted to each other to achieve a stable and detachable connection between the connector 22 and the powder pressing component 3, which also facilitates the convenient installation of the connector 22 and the powder pressing component 3.

[0065] The lower end of the connector 22 may have a groove, in which the first magnetic component may be installed. The end of the powder pressing component 3 facing the connector 22 may have another groove to accommodate the second magnetic component.

[0066] In some embodiments, such as Figures 1 to 3 As shown, the powder receiving assembly 1 also includes a base 14 disposed above the powder receiving cavity 12. The output shaft of the drive member 21 extends through the base 14 into the powder receiving cavity 12. The limiting member 5 is provided with a limiting rod 51 disposed parallel to the trigger member 4. The end of the limiting rod 51 away from the limiting member 5 is used to abut against the base 14 to limit the displacement of the limiting member 5.

[0067] In this way, the limiting rod 51 on the limiting member 5 can be stably pressed against the base 14, thereby limiting the displacement of the limiting member 5 during its upward movement. This prevents the trigger 4 on the limiting member 5 from excessively acting on the first pressure detection component 7, which could damage the first pressure detection component 7. This ensures the service life of the first pressure detection component 7 and the structural stability of the powder pressing device.

[0068] Specifically, it can be combined with Figure 4The trigger 4 can be constructed as a rod, and the base 14 can be provided with a through hole for the trigger 4 to limit the rotation of the limiting member 5, so as to prevent the limiting member 5 from rotating with the powder pressing member 3, and so that the trigger 4 on the limiting member 5 can be stably positioned in the position corresponding to the first pressure detection component 7.

[0069] The base 14 may be provided with a through groove corresponding to the drive member 21. The shape of the through groove is adapted to the outer contour shape of the drive member 21, and the drive member 21 can move up and down in the through groove.

[0070] The aforementioned limiting rod 51 can be one or more, for example, such as Figure 4 As shown, Figure 4 The number of limiting rods 51 shown is two. This application does not specify the number of limiting rods 51, as long as they can effectively limit the displacement of the limiting member 5.

[0071] In some embodiments, such as Figure 3 As shown, the base 14 is provided with a second pressure detection component 9 corresponding to the limiting rod 51. When the limiting rod 51 moves away from the funnel component 11, it acts on the second pressure detection component 9, so that the second pressure detection component 9 generates second pressure feedback information.

[0072] In this way, the real-time performance and accuracy of the pressure applied by the powdered food to the pressing component 3 can be ensured based on the first and second pressure feedback information obtained from the detection.

[0073] The control component can be electrically connected to the second pressure detection component 9. After receiving the first pressure feedback information and the second pressure feedback information, the control component can determine whether one of the pressure values ​​of the first pressure feedback information and the second pressure feedback information exceeds the first preset threshold. If one of them exceeds the first preset threshold, the powder receiving component 1 can stop discharging powder into the receiving cavity 13, thereby further ensuring the accuracy of the detection of the pressure applied by the powdered food to the powder pressing component 3.

[0074] The aforementioned second pressure detection component 9 can be a pressure detection device, specifically a piezoresistive pressure sensor, a capacitive pressure sensor, a piezoelectric pressure sensor, etc. When the limiting rod 51 acts on the second pressure detection component 9, the surface of the second pressure detection component 9 will be pressed and will sense the change of the corresponding parameter. For example, the deformation of the piezoresistive pressure sensor will cause the resistance value to change, which will be converted into an electrical signal through the circuit, thereby realizing the real-time detection of the pressure applied to the limiting rod 51.

[0075] In some embodiments, such as Figures 1 to 3As shown, the powder pressing device also includes a grinding component 8 electrically connected to the control component. The powder outlet of the grinding component 8 is connected to the powder receiving chamber 12. The control component is also used to control the grinding component 8 to stop working when the pressure value of the first pressure feedback information exceeds the first preset threshold.

[0076] In this way, when the pressure value of the first pressure feedback information exceeds the first preset threshold, the grinding component 8 can be controlled to stop working in time, thereby stopping the powder receiving component 1 from dropping powder into the accommodating cavity 13, ensuring that the accommodating cavity 13 has a suitable amount of powder, and ensuring the brewing effect.

[0077] like Figure 1 and Figure 3 As shown, the above-mentioned grinding assembly 8 may include a powder outlet 81, which may be inserted through the base 14 and the powder receiving member to extend into the receiving cavity 13. The lower powder outlet of the powder outlet 81 may be located above the powder pressing member 3 so that the powdered food material falls into the receiving cavity 13 after being rotated and pushed by the powder pressing member 3.
