Description

Technical Field

[0001] This invention relates to the field of coffee machines, and in particular to an automatic coffee powder dispensing device for coffee machines. Background Technology

[0002] In the coffee machine industry, automating coffee making has always been a core goal of technological development. However, in traditional fully automatic or semi-automatic coffee machines, although automatic coffee bean grinding is relatively common, the crucial preparatory steps of adding and tamping coffee grounds before extraction still require manual intervention from the user. The level of automation remains low, affecting coffee making efficiency. Summary of the Invention

[0003] Therefore, it is necessary to provide an automatic coffee powder dispensing and tamping device for coffee machines, which addresses the problem that the addition and tamping of coffee powder in traditional coffee machines requires manual operation by the user, thus affecting the efficiency of coffee making.

[0004] An automatic coffee tamp and dispenser device includes: a support assembly; a grinding assembly disposed on the support assembly and having a powder outlet; a tamp and dispenser assembly disposed on the support assembly, the tamp and dispenser assembly being located on the same side of the support assembly and movable relative to the support assembly; a drive assembly disposed on the support assembly; and an extraction assembly movably disposed on the support assembly and being drivenly connected to the drive assembly, the extraction assembly having an extraction chamber with an opening at its top; the drive assembly is capable of driving the extraction assembly to move relative to the support assembly, the extraction assembly having at least a first position and a second position when moving relative to the support assembly, wherein when the extraction assembly is in the first position, the opening at the top of the extraction chamber is located below the powder outlet; and when the extraction assembly is in the second position, the opening at the top of the extraction chamber is located below the tamp and dispenser assembly.

[0005] This application discloses an automatic coffee tamp and dispensing device for a coffee machine. A drive assembly is connected to the extraction assembly to drive the extraction assembly to move on a support assembly, achieving automatic switching between the coffee powder receiving and tamping positions. Specifically, when the drive assembly drives the extraction assembly to the first position, the opening at the top of the extraction chamber is precisely positioned below the coffee powder outlet of the grinding assembly, thus automatically and completely receiving the coffee powder ground by the grinding assembly, avoiding the tedious manual receiving process. Subsequently, the drive assembly moves the extraction assembly, now holding the coffee powder, to the second position, precisely aligning the opening of the extraction chamber with the bottom of the tamping assembly. At this point, the tamping part of the tamping assembly automatically moves down to complete the automatic tamping operation. This design enables a continuous automated process from grinding and receiving to tamping, providing the necessary conditions for coffee extraction without any manual transfer or intervention, thus improving coffee making efficiency. The automatic tamping design, replacing manual tamping, ensures that the extruded coffee puck has a uniform density and a smooth surface, laying a solid foundation for the subsequent even penetration of hot water into the puck and achieving stable and high-quality extraction.

[0006] In one embodiment, the extraction component has a third position and a fourth position when moving relative to the support component. These third and fourth positions represent the extreme positions of the extraction component's movement, with the first and second positions both located between the third and fourth positions. By having the extraction component have these third and fourth positions when moving relative to the support component, sufficient travel of the extraction component is ensured, thereby guaranteeing that the extraction component can be positioned below the powder outlet and the powder pressing component to collect and press the powder.

[0007] In one embodiment, the extraction assembly includes a movable component and an extraction hopper. The movable component is movably mounted on the support assembly and is drively connected to the drive assembly. The movable component has a receiving groove, and the extraction hopper is mounted on the movable component and located within the receiving groove. The extraction hopper has the extraction chamber. The movable component can support the extraction hopper, allowing it to move with the movable component. This enables automatic switching of the extraction hopper's working position during coffee receiving and tamping, resulting in a high degree of automation and effectively improving coffee making efficiency.

[0008] In one embodiment, one of the moving component and the supporting component is provided with a guide block, and the other of the moving component and the supporting component is provided with a guide groove, the guide block being adapted to the guide groove. Through the movable cooperation between the moving component and the supporting component via the guide block and guide groove, precise guidance is provided for the movement of the extraction component, ensuring that the moving component, driven by the drive component, can always slide smoothly and steadily along a preset path. This guarantees that the extraction powder hopper can accurately reach the first powder receiving position and the second powder pressing position, improving positioning accuracy and making the powder receiving and pressing operations smoother.

[0009] In one embodiment, the moving component includes a support block, a first protrusion, and a second protrusion. Both the first and second protrusions are disposed on the support block, located on opposite sides of the support block. The first protrusion and the support block enclose the receiving groove, and the second protrusion and the support block enclose the guide groove. The receiving groove, formed by the first protrusion and the support block to support and position the extraction powder hopper, ensures the stability of the extraction powder hopper during movement. The guide groove, formed by the second protrusion and the support block, cooperates with the guide block on the support assembly, enabling stable movement of the moving component. This design allows a single moving component to simultaneously perform the dual functions of supporting the extraction powder hopper and forming a sliding pair with the support assembly, eliminating the need for additional connecting parts and guiding components, resulting in a more compact overall structure.

[0010] In one embodiment, the support assembly includes a first support member and a second support member. The second support member is disposed on the first support member and has a mounting hole and a mounting cavity. The grinding assembly is disposed on the first support member and / or the second support member, and the portion of the grinding assembly with the powder outlet mates with the mounting hole. The tamping assembly is disposed on the second support member and located in the mounting cavity. The extraction assembly is movably disposed on the second support member and is movable along the length of the second support member. By having the portion of the grinding assembly with the powder outlet mate with the mounting hole, and by having the tamping assembly and the extraction assembly disposed on the second support member, the support assembly simultaneously functions to cooperate with the grinding assembly to output the coffee powder ground by the grinding assembly to the extraction assembly located below the support assembly; to provide a mounting position for the tamping assembly to ensure smooth tamping; and to provide a movement path for the extraction assembly to ensure smooth powder collection and tamping. This design results in fewer parts, lower cost, and a more compact structure.

[0011] In one embodiment, the system further includes a first limit switch and a second limit switch, both of which are disposed on the first support member. The first and second limit switches are located at opposite ends of the first support member. A trigger is formed on the extraction component. When the extraction component moves along the length of the second support member, the trigger can abut against the first and second limit switches respectively. By allowing the trigger to abut against the first and second limit switches when the extraction component moves, the movement of the extraction component can be limited. For example, when the extraction component is in a first position, it can abut against the first limit switch; when it is in a second position, it can abut against the second limit switch. This design limits the stroke of the extraction component between the first and second positions, preventing overtravel of the extraction component. It also reduces the length of the support member, making the overall structure more compact and cost-effective.

[0012] In one embodiment, the second support member includes a support plate, a guide block, and a mounting cylinder. The support plate has the mounting hole. The guide block and the mounting cylinder are both disposed on the support plate, with the guide block and the mounting cylinder located on adjacent sides of the support plate. The extraction assembly is movably coupled to the guide block and can move along the length of the guide block. The mounting cylinder has the mounting cavity. The arrangement of the support plate, guide block, and mounting cylinder allows the second support member to integrate and mount the grinding assembly, tamping assembly, and extraction assembly, ensuring the accuracy and stability of the relative positions of each component and providing a solid structural guarantee for the reliable execution of the automated process.

[0013] In one embodiment, the coffee grinding assembly includes a grinder and a powder dispensing component. The support assembly has a mounting hole, the grinder is mounted on the support assembly, one end of the powder dispensing component engages with the mounting hole and has a powder outlet, and the other end of the powder dispensing component is connected to the grinder. This powder dispensing component design allows for stable powder dispensing even when the grinder's installation position is adjusted as needed, ensuring that the coffee powder is accurately collected by the extraction assembly directly below it.

[0014] In one embodiment, a baffle structure is further included. This baffle structure is movably disposed on the powder dispensing component and located at the powder outlet. The baffle structure is rotatable relative to the powder dispensing component, and its rotation opens or closes the powder outlet. Specifically, in the non-powder-collecting state, the baffle structure keeps the powder outlet closed, effectively preventing accidental leakage of any coffee powder residue that may remain in the grinder. When powder collection is needed, the baffle structure is rotated relative to the powder dispensing component to open the powder outlet, allowing the coffee powder to fall smoothly into the extraction component below. This design avoids manual intervention and achieves automated control of the powder dispensing process.

[0015] In one embodiment, a push block is formed on the extraction assembly. When the extraction assembly moves relative to the support assembly, the push block abuts against the baffle structure. When the push block abuts against the baffle structure, it drives the baffle structure to rotate relative to the powder dispensing part. During the process of the extraction assembly moving to the first position driven by the drive assembly, the push block contacts the baffle structure and applies a pushing force, driving the baffle structure to rotate relative to the powder dispensing part, thereby automatically opening the powder dispensing port. When the powder dispensing is complete and the extraction assembly moves towards the second position, the push block separates from the baffle structure. The baffle structure automatically rotates under the action of gravity or a reset structure, closing the powder dispensing port. This design effectively prevents coffee powder leakage.

[0016] In one embodiment, the powder pressing assembly includes a powder pressing motor, a screw, and a powder presser. A support assembly has a mounting cavity. The powder pressing motor is mounted on the support assembly, and the screw is mounted on the powder pressing motor and located within the mounting cavity. The powder presser is driven by the screw and can move in a direction extending into or out of the extraction chamber under the drive of the screw. Using the powder pressing motor as a power source, the screw is rotated, thereby driving the powder presser, which is driven by the screw, to move linearly. This design allows the powder presser to move stably towards the extraction chamber under precise motor control to perform the powder pressing operation.

[0017] In one embodiment, the system further includes a housing assembly, on which the support assembly is disposed. The housing assembly has a receiving cavity. The drive assembly includes a drive motor and a drive gear. The drive motor is disposed on the housing assembly and located within the receiving cavity. The drive gear is disposed on the output shaft of the drive motor and is in a transmission engagement with the extraction assembly. Specifically, the drive gear is transmissionally connected to the moving part of the extraction assembly. One side of the transmission part forms a rack-like structure that engages with the drive gear, thereby converting rotational motion into linear movement of the extraction assembly and ensuring stable implementation of powder receiving and pressing operations.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0022] like Figure 1-15 As shown, this embodiment discloses an automatic coffee maker tamping device, comprising: a support assembly 1; a grinding assembly 2, which is disposed on the support assembly 1 and has a powder outlet 201; a tamping assembly 3, which is disposed on the support assembly 1, and the tamping assembly 3 and the grinding assembly 2 are located on the same side of the support assembly 1, and the tamping assembly 3 is movable relative to the support assembly 1; a drive assembly 4, which is disposed on the support assembly 1; and an extraction assembly 5, which is movably disposed on the support assembly 1. 5 is connected to the driving component 4. The extraction component 5 is provided with an extraction chamber 501, and the top of the extraction chamber 501 is provided with an opening 502. The driving component 4 can drive the extraction component 5 to move relative to the support component 1. When the extraction component 5 moves relative to the support component 1, it has at least a first position and a second position. When the extraction component 5 is in the first position, the opening 502 at the top of the extraction chamber 501 is located below the powder outlet 201. When the extraction component 5 is in the second position, the opening 502 at the top of the extraction chamber 501 is located below the powder pressing component 3.

[0023] This application discloses an automatic coffee tamp and dispensing device for a coffee machine. A drive assembly 4 is connected to an extraction assembly 5 to drive the extraction assembly 5 to move on a support assembly 1, achieving automatic switching between the coffee powder receiving and tamping positions. Specifically, when the drive assembly 4 drives the extraction assembly 5 to the first position, the opening 502 at the top of the extraction chamber 501 is precisely positioned below the coffee powder outlet 201 of the grinding assembly 2, thus automatically and completely receiving the coffee powder ground by the grinding assembly 2, avoiding the tedious manual receiving process. Subsequently, the drive assembly 4 moves the extraction assembly 5, now holding the coffee powder, to the second position, so that the opening 502 of the extraction chamber 501 is precisely aligned with the bottom of the tamping assembly 3. At this point, the tamping part of the tamping assembly 3 can automatically move downwards to complete the automatic tamping operation. This design enables a continuous automated process from grinding and receiving to tamping, providing the necessary conditions for coffee extraction without any manual transfer or intervention, thereby improving coffee making efficiency. The automatic tamping design, which replaces manual tamping, ensures that the coffee puck has a uniform density and a smooth surface, laying a solid foundation for the subsequent even penetration of hot water into the puck and achieving stable and high-quality extraction.

[0024] In addition to the features of the above embodiments, this embodiment further specifies that: when the extraction component 5 moves relative to the support component 1, it also has a third position and a fourth position, the third position and the fourth position being the extreme positions of the movement of the extraction component, and the first position and the second position being located between the third position and the fourth position. By having the extraction component 5 have a third position and a fourth position when moving relative to the support component 1, sufficient travel of the extraction component 5 is ensured, thereby guaranteeing that the extraction component 5 can be positioned below the powder outlet 201 and the powder pressing component 3 to collect and press powder.

[0025] like Figure 5-8 and Figure 12-13 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the extraction component 5 includes a movable component 51 and an extraction powder hopper 52. The movable component 51 is movably disposed on the support component 1 and is connected to the drive component 4. The movable component 51 is provided with a receiving groove 503. The extraction powder hopper 52 is disposed on the movable component 51 and located at the receiving groove 503. The extraction powder hopper 52 is provided with the extraction chamber 501. The movable component 51 can support the extraction powder hopper 52, allowing the extraction powder hopper 52 to move with the movable component 51. This achieves automatic switching of the working position of the extraction powder hopper 52 when receiving and tamping powder, resulting in a high degree of automation and effectively improving coffee making efficiency.

[0026] like Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: one of the moving member 51 and the supporting component 1 is provided with a guide block 122, and the other of the moving member 51 and the supporting component 1 is provided with a guide groove 504, and the guide block 122 is adapted to the guide groove 504. Through the movable cooperation between the moving member 51 and the supporting component 1 via the guide block 122 and the guide groove 504, precise guidance is provided for the movement of the extraction component 5, ensuring that the moving member 51 can always slide smoothly and steadily along the preset path when moving under the drive component 4. This ensures that the extraction powder hopper 52 can accurately reach the first powder receiving position and the second powder pressing position, improving positioning accuracy and making the powder receiving and pressing operations smoother.

[0027] like Figure 12 and Figure 13 As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the moving member 51 includes a support block 511, a first protrusion 512, and a second protrusion 513. Both the first protrusion 512 and the second protrusion 513 are disposed on the support block 511, located on opposite sides of the support block 511. The first protrusion 512 and the support block 511 enclose the receiving groove 503, and the second protrusion 513 and the support block 511 enclose the guide groove 504. The receiving groove 503, formed by the first protrusion 512 and the support block 511 for supporting and positioning the extraction powder hopper 52, ensures the stability of the extraction powder hopper 52 during movement. The guide groove 504, formed by the second protrusion 513 and the support block 511, cooperates with the guide block 122 on the support assembly 1, thus achieving stable movement of the moving member 51. This design allows a single moving part 51 to simultaneously serve the dual functions of carrying the extraction powder hopper 52 and forming a sliding pair with the support component 1, eliminating the need for additional connecting parts and guide parts, and making the overall structure more compact.

[0028] like Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support component 1 includes a first support member 11 and a second support member 12, the second support member 12 is disposed on the first support member 11, the second support member 12 is provided with a mounting hole 101 and a mounting cavity 102, the grinding component 2 is disposed on the first support member 11 and / or the second support member 12, and the portion of the grinding component 2 with the powder outlet 201 cooperates with the mounting hole 101, the tamping component 3 is disposed on the second support member 12 and located at the mounting cavity 102, and the extraction component 5 is movably disposed on the second support member 12, and the extraction component 5 is movable along the length direction of the second support member 12. The coffee grinder 2 has a powder outlet 201 that mates with the mounting hole 101, and the tamping assembly 3 and extraction assembly 5 are mounted on the second support 12. This allows the support 1 to simultaneously function as a component that works with the grinder 2 to deliver the coffee powder grounds to the extraction assembly 5 located below it; provides a mounting position for the tamping assembly 3 to ensure smooth tamping; and provides a movement path for the extraction assembly 5 to ensure smooth powder collection and tamping. This design results in fewer parts, lower cost, and a more compact structure.

[0029] like Figure 3-5 As shown, in addition to the features of the above embodiments, this embodiment further includes: a first limit switch 6 and a second limit switch 7, both of which are disposed on the first support member 11. The first limit switch 6 and the second limit switch 7 are respectively located at both ends of the first support member 11 and are disposed opposite to each other. A trigger member 514 is formed on the extraction component 5. When the extraction component 5 moves along the length direction of the second support member 12, the trigger member 514 can abut against the first limit switch 6 and the second limit switch 7 respectively. By allowing the trigger member 514 to abut against the first limit switch 6 and the second limit switch 7 respectively when the extraction component 5 moves, the movement of the extraction component 5 can be limited. For example, when the extraction component 5 is in the first position, it can abut against the first limit switch 6, and when the extraction component 5 is in the second position, it can abut against the second limit switch 7. This design can limit the stroke of the extraction component 5 between the first and second positions, preventing the extraction component 5 from overtraveling. This design can reduce the length of the support member 1, making the overall structure more compact and the cost lower.

[0030] like Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines the second support member 12 as follows: the second support member 12 includes a support plate 121, a guide block 122, and a mounting cylinder 123. The support plate 121 is provided with the mounting hole 101. The guide block 122 and the mounting cylinder 123 are both disposed on the support plate 121, and the guide block 122 and the mounting cylinder 123 are respectively located on adjacent sides of the support plate 121. The extraction component 5 is movably engaged with the guide block 122, and the extraction component 5 can move along the length direction of the guide block 122. The mounting cylinder 123 is provided with the mounting cavity 102. The arrangement of the support plate 121, the guide block 122, and the mounting cylinder 123 enables the second support member 12 to integrate and install the grinding component 2, the tamping component 3, and the extraction component 5, ensuring the accuracy and stability of the relative positions between the components and providing a solid structural guarantee for the reliable execution of the automated process.

[0031] like Figure 2 , Figure 6 and Figure 15 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the coffee grinding assembly 2 includes a grinder 21 and a powder outlet 22; the support assembly 1 has a mounting hole 101; the grinder 21 is disposed on the support assembly 1; one end of the powder outlet 22 engages with the mounting hole 101 and has a powder outlet 201; and the other end of the powder outlet 22 is connected to the grinder 21. The powder outlet 22 allows for stable powder dispensing even when the installation position of the grinder 21 is set as needed, ensuring that the coffee powder is accurately collected by the extraction assembly 5 directly below it.

[0032] like Figure 2 and Figure 14-15 As shown, in addition to the features of the above embodiments, this embodiment further includes a baffle structure 8, which is movably disposed on the powder dispensing component 22 and located at the powder outlet 201. The baffle structure 8 is rotatable relative to the powder dispensing component 22, and when rotating relative to the powder dispensing component 22, it can open or close the powder outlet 201. Specifically, when not dispensing powder, the baffle structure 8 keeps the powder outlet 201 closed, effectively preventing accidental leakage of any coffee powder that may remain in the grinder 21. When dispensing powder, the baffle structure 8 is rotated relative to the powder dispensing component 22 to open the powder outlet 201, allowing the coffee powder to fall smoothly into the extraction component 5 below. This design avoids manual intervention and achieves automated control of the powder dispensing process.

[0033] like Figure 2 and Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a pushing block 515 is formed on the extraction component 5; when the extraction component 5 moves relative to the support component 1, the pushing block 515 can abut against the baffle structure 8; when the pushing block 515 abuts against the baffle structure 8, the pushing block 515 can drive the baffle structure 8 to rotate relative to the powder outlet 22. During the process of the extraction component 5 being driven by the drive component 4 to move to the first position, the pushing block 515 will contact the baffle structure 8 and apply a pushing force, driving the baffle structure 8 to rotate relative to the powder outlet 22, thereby automatically opening the powder outlet 201. When the powder collection is completed and the extraction component 5 moves towards the second position, the pushing block 515 will separate from the baffle structure 8; the baffle structure 8 will automatically rotate under the action of gravity or a reset structure, closing the powder outlet 201. This design can effectively prevent coffee powder leakage.

[0034] like Figure 8 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the powder pressing assembly 3 includes a powder pressing motor 31, a screw 32, and a powder presser 33; the support assembly 1 has a mounting cavity 102; the powder pressing motor 31 is mounted on the support assembly 1; the screw 32 is mounted on the powder pressing motor 31 and located in the mounting cavity 102; the powder presser 33 is driven by the screw 32 and can move in the direction of extending into or out of the extraction chamber 501 under the drive of the screw 32. Using the powder pressing motor 31 as a power source, the screw 32 is driven to rotate, thereby driving the powder presser 33, which is driven by the screw 32, to move linearly. This design allows the powder presser 33 to move stably towards the extraction chamber 501 under the precise control of the motor to perform the powder pressing operation.

[0035] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that it also includes a housing assembly 9, the support assembly 1 is disposed on the housing assembly 9, the housing assembly 9 has a receiving cavity, the drive assembly 4 includes a drive motor 41 and a drive gear 42, the drive motor 41 is disposed on the housing assembly 9 and located in the receiving cavity, the drive gear 42 is disposed on the output shaft of the drive motor 41, and the drive gear 42 is in a transmission engagement with the extraction assembly 5. Specifically, the drive gear 42 is in a transmission connection with the moving part 51 of the extraction assembly 5, and one side of the transmission part forms a rack-like structure that engages with the drive gear 42, thereby converting the rotational motion into the linear movement of the extraction assembly 5, ensuring that the powder receiving and pressing operations can be stably implemented.

[0036] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
