[0004] The utility model embodiment provides a coffee machine's powder pressing device, including:

[0005] The powder receiving assembly includes a funnel assembly and a powder receiving cavity arranged above the funnel assembly, and the funnel assembly has a containing cavity for receiving powder-shaped food materials from the powder receiving cavity;

The output shaft of the drive member extends through the base into the powder receiving cavity. The lifting and limiting structure is provided with a limiting rod arranged parallel to the trigger rod. A second elastic member is sleeved on the limiting rod. The ends of both the first and second elastic members away from the limiting rod abut against the base. The second elastic member cooperates with the first elastic member to apply a force to the rotating powder pressing member to compress the powdered food.

[0017] 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 cavity.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model provides a coffee tamping device for a coffee machine. For example... Figures 1 to 4 As shown, the powder pressing device includes a powder receiving assembly 1, a powder pressing assembly 2, a first switch assembly 7, and a control assembly (not shown in the figure). 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 powder pressing assembly 2 is movably disposed within the receiving cavity 12 to perform a lifting and lowering movement relative to or away from the funnel assembly 11 within the receiving cavity 12. The powder pressing assembly 2 includes an elastic trigger 4 and a rotating powder pressing member 3 rotatably disposed within the receiving cavity 13. The rotating powder pressing member 3 is used to rotate and press powder within the receiving cavity 13 when powder falls from the receiving cavity 12 into the receiving cavity 13. The elastic trigger 4 is used to apply a force to the rotating powder pressing member 3 to compress the powdered food. The first switch assembly 7 is correspondingly disposed with the elastic trigger 4. The elastic trigger 4 is used to trigger the first switch assembly 7 when moving in a direction away from the funnel assembly 11, causing the first switch assembly 7 to generate a first positioning information. The control component is electrically connected to the first switch component 7 and is used to stop the powder receiving component 1 from discharging powder into the receiving cavity 13 when it receives the first positioning information sent by the first switch component 7.

[0031] 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.

[0032] The funnel assembly 11 may include a powder bowl, which forms the receiving cavity 13. Powdered ingredients are placed inside the powder bowl, and the rotating powder pressing component 3 is used to rotate and 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 rotating pressing component 3 continuously rotates and presses the powder within the containing cavity 13, the rotating pressing component 3 will be subjected to a reaction force exerted by the powdered food. When the reaction force exceeds a certain threshold, the rotating pressing component 3 and the elastic trigger 4 will move synchronously away from the funnel assembly 11, that is, the rotating pressing component 3 and the elastic trigger 4 will move upward synchronously. This causes the elastic trigger 4 to trigger the first switch assembly 7, which generates first positioning information. This first positioning information indicates that the elastic trigger 4 has reached the position that triggers the first switch assembly 7. Thus, based on the first positioning information generated by the first switch assembly 7, it can be determined that the rotating pressing component 3 has risen to a preset height. At this time, the powdered food in the containing cavity 13 has a suitable amount of powder, and the rotating pressing component 3 has fully pressed the powder. The receiving assembly 1 can be stopped from falling powder into the containing cavity 13 by the control component, thereby achieving precise control over the amount of powdered food in the containing cavity 13 and the pressing effect of the rotating pressing component 3, which is beneficial to ensuring the brewing effect of the beverage. That is, after the control component receives the first positioning information, it can automatically control the powder receiving component 1 to stop discharging powder into the receiving cavity 13, so that no manual operation is required by the user, thus improving the convenience of use.

[0034] Under the action of the elastic trigger 4, the rotating powder pressing component 3 will press the powdered food. As the powder receiving cavity 12 continuously drops powder into the receiving cavity 13, the reaction force exerted by the powdered food on the rotating powder pressing component 3 gradually increases. This will overcome the force exerted by the elastic trigger 4, allowing the rotating powder pressing component 3 to move upward synchronously with the elastic trigger 4 to move away from the funnel assembly 11. This will enable the elastic trigger 4 to trigger the first switch assembly 7.

[0035] The aforementioned control component can stop the powder receiving component 1 from discharging powder into the receiving cavity 13 by closing the powder receiving cavity 12, or by closing the grinding component 8 that grinds powdered food (see below).

[0036] The first switch component 7 mentioned above can be a micro switch or other energized device that can generate first position information after being triggered. This application does not limit the specific structural form of the first switch component 7, as long as it can be triggered to generate an electrical signal.

[0037] 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.

[0038] This invention utilizes a rotating powder pressing component 3 to press powder within the receiving cavity 13 as it falls from the receiving cavity 12. An elastic trigger 4 applies a force to the rotating powder pressing component 3 to compact the powdered ingredients. This allows for uniform compaction of the powdered ingredients within the receiving cavity 13, and enables simultaneous powder feeding and pressing, improving the pressing effect. Furthermore, the elastic trigger 4, as the rotating powder pressing component 3 moves away from the funnel assembly 11, triggers the first switch assembly 7, generating a first positioning information. Upon receiving this information, the control assembly stops the receiving cavity 1 from discharging powder into the receiving cavity 13. This ensures precise control over the amount of powdered ingredients within the receiving cavity 13 and the pressing effect of the rotating powder pressing component 3, preventing excessive powder accumulation and effectively improving the taste of beverages prepared from the powdered ingredients within the receiving cavity 13.

[0039] In some embodiments, such as Figures 1 to 3 As shown, the powder pressing assembly 2 also includes a drive component 21. The output shaft of the drive component 21 extends into the powder receiving cavity 12 and drives the rotating powder pressing component 3 to rotate and press powder in the receiving cavity 13. The drive component 21 is electrically connected to the control component. The control component is also used to control the drive component 21 to stop working after receiving the first positioning information.

[0040] In this way, the control component can control the drive component 21 to stop working after receiving the first positioning information, so as to ensure that the amount of powder in the accommodating cavity 13 is appropriate, and that the rotating powder pressing component 3 stops rotating after pressing the powder appropriately, thereby achieving a better powder pressing effect and further ensuring the brewing effect of the beverage.

[0041] 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 driving member 21 of the 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 rotating powder pressing member 3 located in the receiving cavity 13.

[0042] In some embodiments, such as Figures 1 to 4As shown, the powder pressing assembly 2 also includes a lifting limit structure 5, an elastic trigger 4 is disposed on the lifting limit structure 5, the lifting limit structure 5 is connected to the drive component 21, and the lifting limit structure 5 moves up and down synchronously with the drive component 21 and the rotating powder pressing component 3 in the powder receiving cavity 12, so that after the rotating powder pressing component 3 is subjected to the force of the powdered food, the elastic trigger 4 on the lifting limit structure 5 triggers the first switch assembly 7.

[0043] Thus, by setting the elastic trigger 4 on the lifting limit structure 5 and connecting the lifting limit structure 5 to the drive member 21, a stable connection between the elastic trigger 4 and the drive member 21 can be achieved. The elastic trigger 4 moves upward synchronously with the drive member 21 and the rotating powder pressing member 3 to trigger the first switch assembly 7 upward.

[0044] The aforementioned lifting and limiting structure 5 can be constructed as a plate, with the elastic trigger 4 disposed on the upper plate surface of the lifting and limiting structure 5, and the rotating powder pressing component 3 disposed below the lower plate surface of the lifting and limiting structure 5. Furthermore, the lifting and limiting structure 5 only performs lifting motion and does not rotate. Bearings or other components can be provided between the lifting and limiting structure 5 and the rotating powder pressing component 3 to reduce friction between them.

[0045] In some embodiments, such as Figures 2 to 4 As shown, the elastic trigger 4 includes a trigger rod 41 and a first elastic member 42 sleeved outside the trigger rod 41. The trigger rod 41 is disposed on the lifting and limiting structure 5, and the first elastic member 42 is used to apply a force to the rotating powder pressing member 3 to press the powdered food.

[0046] Thus, the first elastic element 42 can stably apply a force to the rotating powder pressing element 3 through the lifting and limiting structure 5 to compress the powdered food, and the structure design of the trigger rod 41 and the first elastic element 42 is simple and easy to install.

[0047] The first elastic element 42 mentioned above can be specifically a compression spring, which is sleeved outside the trigger rod 41. By acting on the lifting limit structure 5, the driving element 21 and the rotating powder pressing element 3 connected to the lifting limit structure 5 can be subjected to a force pressing towards the accommodating cavity 13.

[0048] 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 lifting and limiting structure 5 is provided with a limiting rod 51 arranged parallel to the trigger rod 41. A second elastic member 52 is sleeved on the limiting rod 51. The ends of the first elastic member 42 and the second elastic member 52 away from the limiting rod 51 both abut against the base 14. The second elastic member 52 is used to cooperate with the first elastic member 42 to apply a force to the rotating powder pressing member 3 to compress the powdered food.

[0049] Thus, the ends of the first elastic element 42 and the second elastic element 52 away from the limiting rod 51 both abut against the base 14, so that the first elastic element 42 and the second elastic element 52 cooperate to apply force to the rotating powder pressing component 3, so that the rotating powder pressing component 3 can better press the powdered food in the accommodating cavity 13, ensuring the structural stability of the powder pressing device.

[0050] The base 14 may be provided with a through hole for the trigger rod 41 to limit the rotation of the lifting limit structure 5 connected to the trigger rod 41, so as to prevent the lifting limit structure 5 from rotating with the rotating powder pressing part 3, and so that the elastic trigger 4 on the lifting limit structure 5 can be stably positioned in the position corresponding to the first switch assembly 7.

[0051] 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.

[0052] The aforementioned limiting rod 51 can be one or more, for example, such as Figure 4 As shown, Figure 4 The number of limit rods 51 shown is two. This application does not specify the number of limit rods 51, as long as they can stably apply force to the rotating powder pressing component 3.

[0053] The aforementioned second elastic element 52 can be specifically a compression spring, which is sleeved outside the limiting rod 51. By acting on the lifting and limiting structure 5, the driving element 21 and the rotating powder pressing element 3 connected to the lifting and limiting structure 5 can both be subjected to a force pressing towards the accommodating cavity 13.

[0054] In some embodiments, such as Figure 3 As shown, the base 14 is provided with a second switch assembly 9 corresponding to the limit rod 51. When the limit rod 51 moves away from the funnel assembly 11, it acts on the second switch assembly 9 to generate a second positioning information.

[0055] In this way, the accuracy of the powder receiving component 1 stopping the powder from falling into the receiving cavity 13 can be ensured by using the first and second positioning information obtained from the detection.

[0056] The control component described above can be electrically connected to the second switch component 9. After receiving at least one of the first positioning information and the second positioning information, the control component can stop the powder receiving component 1 from discharging powder into the receiving cavity 13.

[0057] The aforementioned second switch component 9 can be a micro switch or other energized device that can generate a second position information after being triggered. This application does not limit the specific structural form of the second switch component 9, as long as it can be triggered to generate an electrical signal.

[0058] In some embodiments, such as Figures 5 to 7 As shown, the rotating powder pressing component 3 includes multiple blades 31, and the outer edge of each blade 31 has a groove 32. The 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 they 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] A gap is formed between the blade 31 and the cavity wall of the receiving cavity 13, so that the rotating powder pressing component 3 will not interfere with the receiving cavity 13, which facilitates the rotation of the rotating powder pressing component 3 within the receiving cavity 13. The distance that the powder scraper 6 slides away from the blade 31 is the size of the gap between the blade 31 and the cavity wall of the receiving cavity 13, so that it can directly contact the cavity wall of the receiving cavity 13 during rotation for effective powder sweeping.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] The aforementioned rib structure 61 can be made of an elastic material so that its own deformation cooperates with the rotation of the powder pressing component 3, allowing the powder pressing component 3 to maintain smooth rotation and to have more contact with the cavity wall of the accommodating cavity 13, thereby achieving a better powder sweeping effect.

[0069] In some embodiments, such as Figures 2 to 4 As shown, the 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 rotating powder pressing component 3. The lifting and limiting structure 5 is located above the connector 22.

[0070] Thus, the drive component 21 can drive the rotating powder pressing component 3 to rotate stably through the connector 22, and the lifting limit structure 5 is located above the connector 22, which can avoid interference between the lifting limit structure 5 and the rotating connector 22 and the rotating powder pressing component 3, so that the lifting limit structure 5 can move up and down smoothly in the powder receiving cavity 12.

[0071] The lower end of the aforementioned connector 22 is detachably connected to the rotating powder pressing component 3, specifically by means of snap-fit ​​connection, threaded connection, plug-in connection, magnetic connection, etc.

[0072] The aforementioned connector 22 can be specifically constructed as a connecting shaft, with its two ends connected to the driving component 21 and the rotating powder pressing component 3, respectively.

[0073] In some embodiments, the lower end of the connector 22 is provided with a first magnetic element (not shown in the figure), and the rotating 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 rotating powder pressing component 3 is connected to the lower end of the connector 22.

[0074] 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 rotating powder pressing component 3, which also facilitates the convenient installation of the connector 22 and the rotating powder pressing component 3.

[0075] The lower end of the connector 22 may have a groove, in which the first magnetic component may be installed. The end of the rotating powder pressing component 3 facing the connector 22 may have another groove to accommodate the second magnetic component.

[0076] 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 after receiving the first positioning information.

[0077] In this way, the control component can promptly control the grinding component 8 to stop working after receiving the first arrival information, thereby stopping the powder receiving component 1 from discharging powder into the receiving cavity 13, ensuring that the receiving cavity 13 has the appropriate amount of powder, and ensuring the brewing effect.

[0078] 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 rotating powder pressing member 3 so that the powdered food material falls into the receiving cavity 13 after being rotated and pushed by the rotating powder pressing member 3.

[0079] The aforementioned grinding assembly 8 can be mounted side-by-side with the drive unit 21 on the base 14, so that the structure of the grinding device is more compact and reasonable.

[0080] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of this utility model.
