Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a coffee machine and a coffee powder receiving device. Background Technology

[0002] As coffee grounds fall into the funnel, they can easily splatter outwards with the airflow. To reduce this splattering, a catching ring has been developed to block the space between the funnel and the outlet, thus minimizing flyaways. However, if the design includes a tamping mechanism, this catching ring can interfere with the tamping process.

[0003] In conclusion, how to effectively solve the problem of coffee powder flying is an urgent issue that needs to be addressed by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a coffee powder receiving device that, while having a tamping and weighing structure, can also reduce coffee powder flying. Another purpose of this invention is to provide a coffee machine that includes the above-mentioned coffee powder receiving device, which has the same beneficial effects as the coffee powder receiving device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A coffee powder receiving device, comprising:

[0007] A weighing assembly for weighing coffee powder;

[0008] A tamping assembly for compacting the coffee powder;

[0009] A funnel, wherein the funnel is provided with a cavity for holding the coffee powder;

[0010] The powder receiving ring has one end that overlaps with the pressure hammer assembly. When the powder is falling, the other end of the powder receiving ring has a gap with the funnel. When the powder is pressing, the other end of the powder receiving ring abuts against the funnel.

[0011] Optionally, it also includes a funnel bracket, which is connected to the pressure hammer assembly via a linkage mechanism. When pressing powder, the pressure hammer assembly moves in the direction of pressing powder, causing the funnel bracket and the funnel to move in the opposite direction of pressing powder, so that the funnel abuts against the powder receiving ring.

[0012] Optionally, the funnel support is provided with a first connecting platform, the weighing component is provided with a second connecting platform, and the funnel includes a connecting ear. When the powder is falling, the connecting ear overlaps with the second connecting platform; when the powder is pressed, as the funnel support moves, the connecting ear disengages from the second connecting platform, and the first connecting platform overlaps with the connecting ear.

[0013] Optionally, a gap is left between the powder receiving ring and the funnel bracket, and the powder receiving ring and the funnel bracket are slidably engaged.

[0014] Optionally, the lower outer periphery of the powder receiving ring is provided with a raised edge; the inner wall of the funnel bracket is provided with a boss, which supports the raised edge.

[0015] Optionally, the powder receiving ring is slidably engaged with the pressure hammer assembly, and the funnel pushes the powder receiving ring to move during powder pressing.

[0016] Optionally, the powder receiving ring is fitted onto the outside of the pressure hammer assembly.

[0017] Optionally, it also includes a mounting frame, the mounting frame including a mounting hole for receiving the powder receiving ring, the upper end of the powder receiving ring having an outer edge that overlaps the top of the mounting hole.

[0018] Optionally, the outer wall of the powder receiving ring and the mounting hole are provided with a mutually cooperating protrusion and guide groove.

[0019] This utility model provides a coffee machine, including the coffee powder receiving device described in any of the above-mentioned claims.

[0020] The beneficial effect of this utility model is that the powder receiving ring is set between the pressure hammer assembly and the funnel, and one end of the powder receiving ring forms a docking overlap with the pressure hammer assembly. The docking overlap forms a dynamic sealing channel by cooperating with the inside and outside of the overlap, blocking the path of coffee powder escaping from between the powder receiving ring and the pressure hammer assembly.

[0021] The distance between the other end of the receiving ring and the funnel differs depending on whether it's dispensing or tamping coffee. During the dispensing phase, a gap exists between the receiving ring and the funnel, preventing them from contacting each other and thus avoiding force transmission to the weighing components, ensuring accurate weighing. During the tamping phase, the funnel and the end face of the receiving ring come into contact, forming a tight seal, eliminating the gap between the funnel and the receiving ring, and preventing coffee powder leakage.

[0022] By applying the technical solution provided in this utility model embodiment, even in coffee machines equipped with weighing and tamping functions, the problem of coffee powder flying can be reduced. During the powder falling period, the powder receiving ring and the funnel maintain a gap to avoid disturbance to the symmetrical weighing components due to the contact of the powder receiving ring with the force transmission symmetry, ensuring accurate and reliable weighing of coffee powder, and the powder falls smoothly along the powder receiving ring with a small amount of powder splashing. During tamping, the powder receiving ring and the funnel abut against each other to form a zero-gap barrier, blocking the powder inside and preventing coffee powder from easily leaking out.

[0023] This utility model also provides a coffee machine, including any of the above-mentioned coffee powder receiving devices. Since the above-mentioned coffee powder receiving devices have the aforementioned technical effects, the coffee machine having such a device should also have the corresponding technical effects.

Detailed Implementation

[0037] The core of this utility model is to provide a coffee powder receiving device to reduce the problem of coffee powder flying; another core of this utility model is to provide a coffee machine including the above-mentioned coffee powder receiving device, which has the same beneficial effects as the coffee powder receiving device.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] In one specific embodiment, please refer to Figures 1 to 10 The coffee powder receiving device provided by this utility model includes: a weighing component 5, a funnel 3, a tamping hammer component 1, and a receiving ring 2. The weighing component 5 is used to weigh the coffee powder, the tamping hammer component 1 is used to compact the coffee powder, and the funnel 3 has a cavity for holding the coffee powder. One end of the receiving ring 2 has an overlapping portion with the tamping hammer component 1. When the coffee powder falls into the funnel 3, the other end of the receiving ring 2 has a gap with the funnel 3. When the tamping hammer component 1 compacts the coffee powder, the other end of the receiving ring 2 abuts against the funnel 3.

[0040] In the above structure, the weighing component 5 includes at least a weighing sensor 52 to detect the weight of the coffee powder. Alternatively, in addition to the weighing sensor 52, it also includes a weighing frame 51 on which the weighing sensor 52 is mounted. When the weighing component 5 detects that the amount of coffee powder added to the funnel 3 has reached a set value, it stops dispensing the powder to provide a fixed amount of coffee powder for extraction.

[0041] After the coffee powder is weighed, the powder is in a loose state. The tamping hammer assembly 1 moves towards the funnel 3 to compact the measured amount of coffee powder in the funnel 3. The tamping hammer assembly 1 is driven by a motor / handle to achieve automatic or manual tamping.

[0042] The powder receiving ring 2 is positioned between the pressure hammer assembly 1 and the funnel 3, connecting the space between them to form a powder passage. This provides precise guidance for the coffee powder and minimizes splashing. In this specific implementation, the powder receiving ring 2 is designed as a hollow cylinder, and its inner wall is treated with Teflon or polished to prevent residual powder from adhering.

[0043] Taking the vertical installation of the powder receiving ring 2 shown in the attached figure as an example, the upper end of the powder receiving ring 2 and the pressure hammer assembly 1 are fitted together to form an axially overlapping part. The inner and outer diameters of the overlapping part are precisely matched to form a dynamic sealing channel, blocking the path of coffee powder from escaping between the powder receiving ring 2 and the pressure hammer assembly 1.

[0044] The distance between the lower end of the powder receiving ring 2 and the upper end of the funnel 3 varies depending on the powder falling and pressing process:

[0045] During the powder dispensing stage, a gap is maintained between the lower end of the powder receiving ring 2 and the upper end of the funnel 3, keeping the powder receiving ring 2 and the funnel 3 separate. This prevents external forces from being transmitted to the weighing component 5 through the powder receiving ring 2, ensuring that the weighing accuracy is not disturbed. While ensuring that the powder receiving ring 2 does not contact the funnel 3, the narrower the gap, the smaller the airflow disturbance, and the more thoroughly powder splashing is suppressed, thus achieving the best balance between accurate weighing and efficient powder dispensing.

[0046] During the compaction stage, the upper end face of the funnel 3 abuts against the lower end face of the powder receiving ring 2, forming a dense sealing boundary, eliminating the gap between the funnel 3 and the powder receiving ring 2, and preventing powder leakage.

[0047] In this embodiment, the gap between the powder receiving ring 2 and the funnel 3 can be eliminated by moving the funnel 3 or the powder receiving ring 2 individually, or by moving the funnel 3 and the powder receiving ring 2 simultaneously.

[0048] By applying the technical solution provided in this utility model embodiment, the problem of coffee powder flying can be reduced in coffee machines with weighing and compaction functions. During the powder falling period, there is a gap between the powder receiving ring 2 and the funnel 3, that is, the powder receiving ring 2 does not contact the funnel 3, so as to avoid the powder receiving ring 2 transmitting force to the funnel 3 due to contact between the two, which would affect the weighing accuracy of the weighing component 5 on the coffee powder in the funnel 3. Moreover, the powder falls smoothly along the powder receiving ring 2. Under the blocking and limiting effect of the powder receiving ring 2, the outward splashing of coffee powder can be reduced. During compaction, the powder receiving ring 2 and the funnel 3 abut against each other, and the two fit tightly together to form a zero-gap barrier, preventing coffee powder from leaking out from the connection between the two.

[0049] In some embodiments, based on the original weighing component 5, funnel 3, hammer assembly 1, and powder receiving ring 2, the coffee powder receiving device adds a funnel bracket 4 and a linkage mechanism 7. The funnel bracket 4 and the hammer assembly 1 are connected through the linkage mechanism 7. When tamping, the hammer assembly 1 moves in the tamping direction, which drives the funnel bracket 4 and the funnel 3 to move in the opposite tamping direction so that the funnel 3 abuts against the powder receiving ring 2.

[0050] The linkage mechanism 7 enables the hammer assembly 1 to move the funnel support 4. The two can move synchronously throughout the entire process, or partially synchronously. That is, the linkage mechanism 7 can move the funnel support 4 when the hammer assembly 1 begins to move, or it can move the funnel support 4 after the hammer assembly 1 has moved for a period of time. Specifically, the linkage mechanism 7 can be composed of a slide rail, connecting rod, rocker plate, or cam pair, enabling the hammer assembly 1 to move in the direction of powder pressing, and the funnel support 4 to move in the opposite direction of powder pressing.

[0051] For example, the linkage mechanism 7 includes a first linkage part that moves with the pressure hammer assembly 1, and a second linkage part that moves the funnel bracket 4. The second linkage part moves with the first linkage part. The pressure hammer assembly 1 also serves as the power source for the linkage mechanism 7. The first linkage part is connected to the pressure hammer assembly 1 and can be a follower arm, rack and pinion, or cam plate. One end of the second linkage part cooperates with the first linkage part, and the other end is connected to the funnel bracket 4. It is used to amplify or proportionally convert the downward displacement of the pressure hammer assembly 1 into the upward displacement of the funnel bracket 4. It can be a lever, connecting rod, or wedge.

[0052] When powder is poured into funnel 3, the hammer assembly 1 is in a high position, the linkage mechanism 7 is in a free state, and funnel 3 is stationary; there is a gap between funnel 3 and powder receiving ring 2, and the powder falls in smoothly.

[0053] Once the set amount of coffee powder is reached, the dispensing process ends and tamping begins. The tamping hammer assembly 1 begins its downward movement. The linkage mechanism 7 utilizes the energy generated by the downward compaction of the coffee powder by the tamping hammer assembly 1. The first linkage unit moves downward along with the tamping hammer assembly 1. Through the mechanical gain of the second linkage unit, the displacement direction is reversed and transmitted to the funnel holder 4. This causes the tamping hammer assembly 1 to move in the tamping direction, which in turn drives the funnel holder 4 to move in the opposite direction. Specifically, it drives the funnel holder 4, along with the funnel 3, to rise in the opposite direction of tamping, creating a relative motion of the tamping hammer assembly 1 moving downward and the funnel 3 moving upward. This movement of the funnel 3 eliminates the gap between the funnel 3 and the receiving ring 2 during dispensing, ensuring a zero-gap fit between the lower end of the receiving ring 2 and the upper end of the funnel 3, forming a sealed boundary and preventing coffee powder from dispersing outward from the connection point.

[0054] This application utilizes the stroke energy of the pressure hammer assembly 1 to lift the funnel 3, achieving zero-gap sealing and preventing powder from escaping; and utilizes the movement of the funnel 3 to eliminate the gap between it and the powder receiving ring 2. The powder falling and compaction are driven by a single action chain, requiring no additional drive components, resulting in a simple and ingenious structure.

[0055] In some embodiments, the funnel support 4 is provided with a first connecting platform 41, the weighing component 5 is provided with a second connecting platform 511, and the funnel 3 is provided with a connecting lug 31. Preferably, the first connecting platform 41 extends inward from the inner wall of the funnel support 4, and the second connecting platform 511 extends inward from the inner wall of the weighing component 5. The connecting lug 31 may be a flange, a pin, or a folded edge.

[0056] When coffee powder is dispensed, the connecting ear 31 overlaps with the second connecting platform 511, and the first connecting platform 41 is located below the second connecting platform 511 and the connecting ear 31. That is, the first connecting platform 41 does not contact the connecting ear 31, and the funnel bracket 4 does not apply force to the funnel 3 and the weighing component 5, so as to ensure accurate weighing of coffee powder in the funnel 3.

[0057] During tamping, the tamping hammer assembly 1 starts to descend, and the linkage mechanism 7 drives the funnel holder 4 to move in the opposite direction of tamping. As the funnel holder 4 moves, the connecting ear 31 disengages from the second connecting platform 511, and the first connecting platform 41 engages with the connecting ear 31, so that the funnel holder 4 can drive the funnel 3 to move in the opposite direction of tamping. As the funnel holder 4 continues to rise, the funnel 3 is lifted along with it, and the upper surface of the funnel 3 abuts against the lower surface of the powder receiving ring 2 with zero gap, preventing coffee powder from leaking out.

[0058] In the above structure, during the powder dispensing stage, the first connecting platform 41 and the connecting ear 31 are completely detached, and the entire weight of the funnel 3 is borne by the weighing component 5, ensuring accurate weighing. During the compaction stage, the funnel 3 is detached from the second connecting platform 511 and supported by the funnel bracket 4, preventing the compaction force from being transmitted to the weighing component 5 and improving the service life of the weighing component 5. Furthermore, the connecting ear 31 of the funnel 3 overlaps with the weighing component 5 and the funnel bracket 4, facilitating the connection and switching between the two during powder dispensing and compaction, resulting in a simple and reliable structure.

[0059] In some embodiments, a gap is left between the powder receiving ring 2 and the funnel bracket 4, allowing them to slide together. Specifically, the powder receiving ring 2 is a vertical hollow cylinder, and the funnel bracket 4 is an annular frame, which is fitted onto the outside of the powder receiving ring 2. The axial sliding fit between the powder receiving ring 2 and the funnel bracket 4 allows for relative sliding while suppressing lateral swaying of the funnel bracket 4, ensuring the coaxiality of the sealing surfaces of the funnel 3 and the powder receiving ring 2.

[0060] The lower outer periphery of the powder receiving ring 2 is provided with a raised edge 21, which can be a continuous flange or spaced lugs. Specifically, the raised edge 21 has an inverted structure, the upper surface of the raised edge 21 is a finely machined flat surface, forming a flat load-bearing surface; the lower surface is provided with a draft angle for easy assembly and disassembly. The inner wall of the funnel bracket 4 is provided with a boss 42, which corresponds to the raised edge 21, and can be a ring of bosses 42 or several bosses. The boss 42 supports the raised edge 21. Specifically, the lower surface of the boss 42 and the upper surface of the raised edge 21 fit together. The funnel bracket 4 can apply downward pressure using the boss 42 to keep the powder receiving ring 2 in a low position and also prevent the two from separating.

[0061] When the funnel bracket 4 is driven upward by the linkage mechanism 7, the boss 42 disengages from the upper surface of the protrusion 21 and moves upward along the powder receiving ring 2, driving the funnel 3 to move upward, so that the upper end of the funnel 3 abuts against the lower end of the powder receiving ring 2; when the funnel bracket 4 drives the funnel 3 to move downward and reset, the upper end of the funnel 3 and the lower end of the powder receiving ring 2 return to the initial gap, and the boss 42 presses against the upper surface of the protrusion 21.

[0062] In some embodiments, the powder receiving ring 2 is slidably fitted with the pressure hammer assembly 1. Specifically, the powder receiving ring 2 is fitted outside the pressure hammer assembly 1. The two can be coaxially fitted by a slide rail or a linear bearing to improve the coaxiality of the movement.

[0063] During powder pressing, the funnel 3 pushes the powder receiving ring 2 to move. That is, after the funnel 3 and the powder receiving ring 2 come into contact and fit together, the movement of the funnel 3 can push the powder receiving ring 2 to move. In other words, the gap between the funnel 3 and the powder receiving ring 2 during powder dispensing is less than the displacement of the funnel 3. This allows the gap between the funnel 3 and the powder receiving ring 2 to be designed to be smaller during powder dispensing, reducing the amount of powder flying. Also, because the gap height is less than the upward displacement of the funnel 3, when the funnel 3 moves upward, the upper end face of the funnel 3 first comes into contact with the lower end face of the powder receiving ring 2, and then the funnel 3 drives the powder receiving ring 2 to continue to move upward synchronously, so that the funnel 3 is separated from the weighing component 5. This forms a reliable seal, reduces powder flying, and does not exert force on the weighing component 5 during powder pressing, thus improving the service life of the weighing component 5.

[0064] In some embodiments, a mounting frame 6 is also included, which is designed with mounting holes to accommodate the powder receiving ring 2. Specifically, the mounting holes can accommodate part or all of the powder receiving ring 2. When the powder receiving ring 2 is driven to slide up and down, the mounting holes can act as guides, and the two maintain the same fitting clearance, preventing additional leakage channels from being created due to wear.

[0065] Preferably, the mounting hole wall of the powder receiving ring 2 is precision machined or honed, and the outer wall of the powder receiving ring 2 is hard chrome plated and polished to ensure low friction and long service life. The sliding gap between the two is small, which allows free axial movement while suppressing radial wobble, ensuring that the powder receiving ring 2 is always concentric with the axis of the pressure hammer assembly 1 throughout the entire stroke, avoiding misalignment of the sealing surface and preventing powder from escaping.

[0066] The upper end of the powder receiving ring 2 has an outer edge 22, which overlaps the top of the mounting hole. After the outer edge 22 overlaps, the maximum downward stroke of the powder receiving ring 2 is limited by the frame body to prevent it from slipping off.

[0067] During the powder pressing stage, the funnel 3 moves upward, and the upper end of the funnel 3 first contacts the lower end of the powder receiving ring 2; then the powder receiving ring 2 is lifted up, and the outer edge 22 separates from the mounting frame 6. The downward reaction force on the powder receiving ring 2 is directly transmitted to the frame body through the mounting hole, and then diffused to the whole machine skeleton through the frame body. The weighing component 5 is not affected by the lateral bending moment, thus improving the service life of the weighing component 5.

[0068] Preferably, a recessed platform or annular shoulder is provided at the top of the frame body, and the lower surface of the outer edge 22 directly overlaps the platform plane, forming a combined constraint of upper limit and lower sliding. The lower surface of the outer edge 22 and the platform plane are precision ground, and the outer edge 22 and the platform plane form a rigid reference surface to ensure the coaxiality and parallelism of the lower end of the powder receiving ring 2 and the upper end of the funnel 3 when they are closed, and the sealing gap is uniform and controllable. During the process of the powder receiving ring 2 being lifted and the outer edge 22 separating from the platform, it can still maintain coaxiality within the radial guiding range of the platform.

[0069] In some embodiments, the outer wall of the powder receiving ring 2 is provided with a mating ridge and a guide groove between it and the mounting hole. Specifically, the ridge extends axially and has a trapezoidal, semi-circular, or other suitable cross-section; the guide groove is formed on the corresponding wall surface and its shape is complementary to the ridge. The gap between the ridge and the guide groove ensures smooth sliding and suppresses radial wobble. After the ridge is embedded in the guide groove, the powder receiving ring 2 is only allowed to reciprocate in a straight line along the powder pressing axis, and its rotational freedom is completely constrained. The sealing surfaces always remain coaxial, ensuring that the lower end of the powder receiving ring 2 and the upper end of the funnel 3 are precisely fitted. The lateral force generated during the compaction stage is directly transmitted to the frame body through the ridge-guide groove pair, preventing the force from acting on the weighing component 5.

[0070] Preferably, the length of the protruding ridge is slightly greater than the working stroke of the powder receiving ring 2 to ensure guidance throughout the entire process; the end is provided with an inlet chamfer for easy assembly.

[0071] In some embodiments, the inner diameter of the receiving ring 2 is approximately equal to the diameter of the funnel 3. When coffee powder enters the funnel 3 from the receiving ring 2, there is no abrupt change in cross-section or step obstruction, allowing for smooth powder flow without secondary turbulence or powder buildup, thus preventing powder splatter. As the funnel 3 moves upward, the upper surface of the funnel 3 comes into contact with the lower surface of the receiving ring 2, forming a seal under axial pressure. The sealing pressure increases synchronously with the pressure, effectively isolating fine powder particles. Preferably, both the upper surface of the funnel 3 and the lower surface of the receiving ring 2 are finely ground flat surfaces, allowing for complete contact during the compaction stage, forming a dense, seamless sealing ring.

[0072] Based on the coffee powder receiving device provided in the above embodiments, this utility model also provides a coffee machine, which includes any of the coffee powder receiving devices described in the above embodiments. Since this coffee machine uses the coffee powder receiving device described in the above embodiments, the beneficial effects of this coffee machine are explained in the above embodiments.
