Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to an automatic extraction coffee machine. Background Technology

[0002] In the field of coffee beverage production, especially in mainstream brewing methods such as espresso and pour-over coffee, tamping is a key step after the coffee powder is loaded. Its core purpose is to compact the loose coffee powder into a uniform and dense cake, so that hot water can evenly penetrate the coffee layer during the brewing process, avoiding problems such as over-extraction or under-extraction in some areas, thereby ensuring the flavor balance and stable taste of the coffee. In related technologies, during coffee extraction, coffee beans are typically ground into coffee powder by the coffee machine's grinding mechanism. Then, the extraction bowl of the extraction component is assembled into the coffee machine's powder dispensing position, and the powder is guided into the extraction bowl of the coffee machine's extraction mechanism through the powder dispensing channel.

[0003] After that, the extraction bowl is removed. If tamping is required, the operator needs to hold a special tamper (usually a round metal hammer) and apply pressure with their arm to compact the coffee powder in the bowl. After tamping is completed, the extraction bowl of the extraction component is inserted into the water outlet of the coffee machine to extract the tamped coffee powder.

[0004] Firstly, in related technologies, tamping involves manually pressing the coffee grounds with a tamper, making it difficult to maintain a completely consistent pressure. Insufficient pressure results in a loose coffee puck, which can trigger a "channeling effect" when hot water penetrates quickly, causing some coffee grounds to be over-extracted and produce a bitter taste. Excessive pressure, on the other hand, can cause the coffee puck to be too dense, increasing the resistance to hot water penetration and leading to under-extraction, resulting in a thin coffee flavor and excessive acidity.

[0005] Secondly, during the extraction process, the extraction vessel needs to be placed in the coffee grounds outlet of the coffee machine first. After collecting the coffee grounds, regardless of whether tamping is required, the extraction vessel must be removed from the coffee machine and then placed in the water outlet. The water hose then guides the water flow to the extraction vessel for brewing. This process requires manual handling of the extraction vessel, which is cumbersome and results in low coffee production efficiency. Utility Model Content

[0026] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0027] See Figures 1-13 This utility model discloses an automatic extraction coffee machine, including a body 10, a grinding assembly 20, a water dispensing assembly 60, a moving assembly 40, and an extraction assembly 50. The grinding assembly 20, the water dispensing assembly 60, and the moving assembly 40 are all installed in the body 10. The body 10 is provided with a powder dispensing channel 13, a guide channel, a first position 11, and a second position 12. One end of the powder dispensing channel 13 is connected to the grinding assembly 20, and the other end of the powder dispensing channel 13 is connected to the first position 11. The water dispensing assembly 60 is provided with a water outlet pipe 15, which is connected to the guide channel at the second position 12.

[0028] Specifically, the aforementioned moving component 40 includes a moving base 41 and a moving drive component 42. The moving base 41 is provided with a first connecting portion, and the moving base 41 reciprocates between a first position 11 and a second position 12 under the drive of the moving drive component 42. The extraction component 50 includes an extraction bowl 51, which is provided with a second connecting portion, and the second connecting portion is detachably connected to the first connecting portion. After the extraction bowl 51 is assembled to the moving base 41, the moving base 41 can drive the extraction bowl 51 to move between the first position 11 and the second position 12 under the drive of the moving drive component 42. When the moving base 41 moves to the first position 11, the extraction bowl 51 is connected to the powder outlet channel 13, and when the moving base 41 moves to the second position 12, the extraction bowl 51 is connected to the water outlet pipe 15.

[0029] Based on the above structure, when using the automatic extraction coffee machine of this utility model, the extraction bowl 51 of the extraction assembly 50 is connected to the first connecting part of the moving base 41 through the second connecting part. This allows the extraction bowl 51 to be assembled onto the moving base 41. After assembly, the moving drive 42 moves the moving base 41 to the first position 11, thus placing the extraction bowl 51 in the first position 11 (first usage state, see [reference]). Figure 1 as well as Figure 2 At this time, the powder outlet channel 13 can be connected to the extraction bowl 51. At this time, the grinding component 20 performs the grinding action, and the generated coffee powder can be guided to the extraction bowl 51 through the powder outlet channel 13. After the extraction bowl 51 receives a certain amount of coffee powder, the moving drive component 42 can drive the moving seat 41 to the second position 12 (second use state).

[0030] The movable seat 41 moves to the second position 12 (second usage state, see...). Figure 3 , Figure 4 as well as Figure 5 After that, the extraction bowl 51 on the moving seat 41 can be connected to the guide channel. At this time, the water outlet component 60 of the machine body 10 is activated, so that the water in the coffee machine is guided through the water outlet pipe 15 to the guide channel, and then guided through the guide channel to the extraction bowl 51 to carry out the coffee extraction action.

[0031] Compared to existing technologies, where coffee extraction requires first assembling the extraction bowl 51 to the coffee machine's powder outlet for receiving coffee powder, and then removing and reassembling it to the brewing outlet, resulting in discontinuous extraction and low efficiency, the coffee machine of this application eliminates the need for repeated assembly and disassembly. Instead, the extraction bowl 51 is assembled once onto the moving base 41, which then moves it to position 11 to receive coffee powder. The moving drive 42 then moves the bowl to position 12 for extraction. This eliminates the need for separate assembly and disassembly of the extraction bowl 51, ensuring continuous powder receiving and brewing, thus improving coffee production efficiency.

[0032] Furthermore, in related technologies, in order to enable the extraction bowl 51 to be assembled at both the powder outlet and the brewing outlet of the coffee machine, it is necessary to have a connecting structure that can be detached from the extraction bowl 51 at both locations. After long-term use of the coffee machine, the connecting structures at both locations are prone to accumulating coffee powder or coffee liquid, making cleaning difficult. However, in this application, by setting a movable seat 41 structure, only a connecting structure needs to be set on the movable seat 41 to assemble with the extraction bowl 51. The movable seat 41 can be moved to different positions to complete the powder collection and extraction, simplifying the structure of the coffee machine's powder outlet and brewing outlet. When cleaning the connecting structure, it is only necessary to move the movable seat 41 to a convenient cleaning position using the moving drive 42, making cleaning convenient.

[0033] It should be noted that in the relevant implementation structure, the first position 11 and the second position 12 are located at both ends of the length direction or both sides of the width direction of the body 10, and both the first position 11 and the second position 12 are provided with an opening structure. The movable seat 41 can move back and forth between the two openings of the first position 11 and the second position 12, and can be connected with the powder outlet channel 13 and the guide channel at the corresponding positions.

[0034] In addition, in this embodiment, the first position 11 of the coffee machine is located inside the body 10, while the second position 12 is located outside the body 10. An avoidance groove 14 can be provided on the body 10 to avoid the extraction bowl 51 when the moving seat 41 moves the extraction bowl 51 to the first position 11, thus preventing the extraction bowl 51 from colliding with the body 10 when it moves to the body 10.

[0035] As an optional implementation, see [link to implementation details]. Figure 1 , Figure 3 as well as Figure 5The automatic extraction coffee machine also includes a tamping assembly 30, which includes a guide seat 31, a tamping component 32, and a tamping drive component 33. The guide seat 31 is located inside the machine body 10, and the aforementioned guide channel is located in the guide seat 31. Thus, the tamping component 32 and the tamping drive component 33 are both installed based on the guide seat 31.

[0036] Specifically, the tamping component 32 is installed in the guide channel and can reciprocate along the tamping direction. The tamping component 32 is provided with a tamping end face 321. The tamping drive component 33 is installed on the guide seat 31. The drive component can drive the tamping component 32 to reciprocate. The tamping component 32 can extend into or out of the extraction bowl 51 along the tamping direction (in this embodiment, the tamping direction is described as the up and down direction). The tamping end face 321 is used to compact the coffee powder in the extraction bowl 51 after the tamping component 32 extends into the extraction bowl 51.

[0037] Based on this structure, after receiving coffee powder at the first position 11, the extraction bowl 51 on the movable seat 41 can move to the second position 12 under the drive of the movable drive 42, so that the extraction bowl 51 corresponds to the guide channel at the second position 12. At this time, the tamping drive 33 can be activated first, which can drive the tamping component 32 to move up and down. When the tamping component 32 moves downward, it can extend into the extraction bowl 51. The tamping end face 321322 of the tamping component 32 can contact the coffee powder in the extraction bowl 51 and compact the coffee powder in the extraction bowl 51. In the reciprocating process, the coffee powder in the extraction bowl 51 is gradually compacted into a uniform layer of powder, reducing air bubbles in the coffee powder.

[0038] After the coffee grounds are compacted in the extraction bowl 51, the water outlet assembly 60 is activated, and the water flow inside the coffee machine is guided through the water outlet pipe 15 to the guide channel, and then to the extraction bowl 51. The brewing water is introduced into the extraction bowl 51 and directly brews the compacted coffee grounds. The coffee puck has a uniform density and a dense structure, which can force hot water to penetrate the coffee grounds evenly, ensuring that the soluble substances in the coffee are extracted evenly and avoiding local flavor imbalance.

[0039] In this application, the tamping component 32 is driven by the tamping drive component 33 to reciprocate. Since the driving force applied by the tamping drive component 33 to the tamping component 32 each time is controllable, the force applied by the tamping component 32 to the coffee powder in the extraction bowl 51 can be even and consistent each time. This allows for control over the tamping force, resulting in a uniform tamping force that prevents the coffee powder layer from being too loose or too thick in certain areas, leading to better extraction. Furthermore, it reduces the inconvenience of manual operation, making the process more convenient.

[0040] As an optional implementation, the powder pressing component 32 is provided with a guiding channel that extends along the powder pressing direction. When the powder pressing direction is up and down, the extending direction of the guiding channel is also up and down. In this way, the water outlet pipe 15 is connected to the guiding channel, and the water flow from the water outlet pipe 15 enters the guiding channel and flows from top to bottom into the extraction bowl 51. Thus, the water outlet pipe 15 is connected to the guiding channel of the powder pressing component 32, and the water outlet pipe 15 can be inserted into the guiding channel. During the up and down movement of the powder pressing component 32, the water outlet pipe 15 and the guiding channel slide relative to each other, so that the water outlet pipe 15 will not be pulled during the up and down movement of the powder pressing component 32.

[0041] If the water outlet pipe 15 is directly connected to the guide channel, then the guide channel must have reserved space for the water outlet pipe 15 to connect to. This would cause the water outlet pipe 15 to be pulled during the up-and-down movement of the tamping unit 32, resulting in an uncertain water outlet position. If the water outlet position is too high, coffee liquid may splash; if the water outlet position is too low, coffee powder may stick to the pipe. In this embodiment, however, the water outlet pipe 15 is connected to a fixed guide channel on the tamping unit 32. The water outlet position in the guide channel will not become unstable due to the movement of the water outlet pipe 15, meaning the water outlet position is relatively stable each time, reducing the likelihood of coffee liquid splashing or coffee powder sticking during brewing.

[0042] As an optional implementation, the powder pressing drive 33 includes a first drive motor 331 and a drive head 332. The shaft of the first drive motor 331 is connected to the drive head 332 and drives the drive head 332 to rotate. The drive head 332 is provided with a first transmission part, and the powder pressing component 32 is provided with a second transmission part. The first transmission part and the second transmission part are connected in a transmission manner. The first transmission part is used to cooperate with the second transmission part in a transmission manner when the drive head 332 rotates, so as to guide the powder pressing component 32 to move along the powder pressing direction.

[0043] Based on this structure, when driving the powder pressing component 32, the first drive motor 331 rotates, and the shaft of the first drive motor 331 drives the drive head 332 to rotate. The first transmission part on the drive head 332 can then cooperate with the second transmission part on the powder pressing component 32. In this way, the rotational movement of the drive head 332 can be transmitted by the first transmission part and the second transmission part, which leads to the up and down movement of the powder pressing component 32, thereby realizing the powder pressing action.

[0044] As an optional implementation, the first transmission part includes a first threaded structure, and the second transmission part includes a second threaded structure 322. The first threaded structure and the second threaded structure 322 are threadedly engaged. The powder pressing component 32 is provided with a first guide portion, and the guide seat 31 is provided with a second guide portion. The first guide portion and the second guide portion are slidably engaged to guide the powder pressing component 32 to move in the powder pressing direction. In this way, when the drive block rotates, the first threaded structure can be threadedly engaged with the second threaded structure 322 of the powder pressing component 32. The rotational movement of the powder pressing component 32 can be transformed from the sliding engagement of the first guide portion and the second guide portion into up-and-down movement along the powder pressing direction. That is, the up-and-down movement of the powder pressing component 32 is driven by the threaded rotation, and the movement state is stable.

[0045] More specifically, the first threaded structure is disposed on the outer peripheral wall of the drive head 332; the second threaded structure 322 is disposed on the inner peripheral wall of the powder pressing component 32, and the drive head 332 is rotatably connected to the powder pressing component 32 so that the first threaded structure and the second threaded structure 322 are threadedly engaged. In this way, the drive head 332 and the powder pressing component 32 are threadedly engaged in a fitting manner. After assembly, the powder pressing component 32 is not prone to wobble during up and down movement, and its movement is stable.

[0046] As an optional implementation, the first guide portion includes a guide block disposed on the outer peripheral wall of the powder pressing component 32; the second guide portion includes a guide groove disposed on the guide seat 31 and extending along the powder pressing direction; the guide block slides through the guide groove, so that when the first threaded structure of the drive head 332 is assembled with the second threaded structure 322 of the powder pressing component 32, the rotational movement of the powder pressing component 32 is limited by the sliding engagement between the guide block and the guide groove, and thus converted into up-and-down movement.

[0047] As an optional implementation, a detection switch 311 is provided on the brewing base. The detection switch 311 is positioned in the powder pressing direction, so that when the guide block slides along the guide groove, it touches the detection switch 311. The detection switch 311 can be located at both ends of the guide groove. When the powder pressing component 32 moves upward to the highest position, the detection switch 311 can be touched, at which time the detection switch 311 can control the powder pressing drive component 33 to close, and the movement of the powder pressing component 32 returns to its original position. If the detection switch 311 is located at the other end of the guide groove, it can also be touched when the powder pressing component 32 moves downward to the lowest position, and the powder pressing drive component 33 can also be closed in time, thus controlling the movement stroke of the powder pressing component 32.

[0048] Of course, the first and second transmission parts mentioned above can also be selected as gears and racks for transmission, with the shaft of the first drive motor 331 driving the gear on the drive head 332 to rotate, thereby driving the rack meshing with the gear to move up and down.

[0049] As an optional implementation, see [link to implementation details]. Figure 1 , Figure 3 , Figure 12 as well as Figure 13 The aforementioned moving drive component 42 includes a second drive motor 421 and a drive screw 422. A threaded hole is provided in the moving base 41. The drive screw 422 is rotatably mounted on the machine body 10, and the moving base 41 is slidably mounted on the machine body 10. Specifically, the drive screw 422 is threaded into the threaded hole of the moving base 41. Thus, the second drive motor 421 drives the drive screw 422 to rotate, and the rotation of the drive screw 422 guides the moving base 41 to reciprocate between the first position 11 and the second position 12.

[0050] That is, the second drive motor 421 drives the drive screw 422, and the drive screw 422 engages with the threaded hole of the moving seat 41 to move the moving seat 41. The threaded transmission has high precision and can accurately move the moving seat 41 to the first position 11 or the second position 12. Moreover, after the moving seat 41 moves into position, due to the thread limit, the moving seat 41 is not easy to shake during extraction, brewing or powder collection, making the use process more stable.

[0051] As an optional implementation, a touch unit 414 can be provided on the movable base 41, and touch switches can be provided at both the first position 11 and the second position 12. The touch unit 414 is used to activate the touch switches, and the touch switches are electrically connected to the second drive motor 421. Based on this structure, when the movable base 41 moves the extraction bowl 51 to the first position 11, the touch unit 414 on the movable base 41 can trigger the touch switches. After being triggered, the touch switches can send a signal, and the second drive motor 421 can stop according to the trigger signal. In this way, the movable base 41 can stop at the first position 11. It should be noted that the position where the touch unit 414 triggers the touch switches can be set so that the extraction bowl 51 corresponds exactly to the powder outlet channel 13 at the first position 11 to prevent powder leakage due to misalignment.

[0052] Similarly, when the moving seat 41 moves the extraction bowl 51 to the second position 12, the touch unit 414 on the moving seat 41 can trigger the touch switch. After the touch switch is triggered, it can send a signal, and the second drive motor 421 can stop according to the trigger signal. In this way, the moving seat 41 can stop at the second position 12. It should be noted that the position where the touch unit 414 triggers the touch switch can be set so that the extraction bowl 51 corresponds exactly to the powder outlet channel 13 at the second position 12 to prevent water leakage due to misalignment.

[0053] It should be noted that the aforementioned touch switch can be a Hall switch as used in the prior art, while the touch unit 414 can be a magnetic structure, with the magnet triggering the signal through the Hall switch. Alternatively, the touch switch can be a photoelectric switch or a contact switch, in which case the touch unit 414 can be a touch block or a touch sheet, etc., to achieve signal triggering. The specific selection and setting can be made according to actual needs.

[0054] As an optional implementation, the aforementioned moving drive component 42 further includes a driving gear 423 and a driven gear 424, and two driving screws 422 are provided; threaded through holes are provided on both sides of the moving base 41; the two driving screws 422 are respectively threaded through the two threaded through holes; the driving gear 423 is connected to the shaft of the second drive motor 421; both driving screws 422 are connected to the driven gear 424, and the driven gear 424 meshes with the driving gear 423.

[0055] Based on this structure, when the movable seat 41 is driven, the second drive motor 421 is started. The second drive motor 421 drives the drive gear 423 to rotate. The drive gear 423 can drive the transmission gears on both sides, which can drive the two drive screws 422 to rotate synchronously. The two drive screws 422 can drive the movable seat 41 synchronously on both sides of the movable seat 41. In this way, the driving force on the movement is stable, preventing tipping or tilting during the movement, and making the movement process more stable.

[0056] Of course, the aforementioned moving drive component 42 can also be implemented using existing drive structures such as electric push rods or cylinders.

[0057] As an optional implementation, to facilitate the assembly and disassembly of the extraction bowl 51 and the movable seat 41, a through groove 411 is provided on the movable seat 41. The through groove 411 extends to both the top and bottom of the movable seat 41. When the movable seat 41 moves to the first position 11, the through groove 411 connects with the powder outlet channel 13 of the first position 11. When the movable seat 41 moves to the second position 12, the through groove connects with the guide channel of the second position 12. After the extraction bowl 51 is assembled onto the movable seat 41, it can simply be positioned within the through groove and connected to it.

[0058] Specifically, a snap-fit ​​groove 412 and a snap-fit ​​notch 413 are provided circumferentially on the through groove 411; the snap-fit ​​groove 412 extends circumferentially along the movable seat 41; the snap-fit ​​notch 413 is provided at one end of the snap-fit ​​groove 412; a snap-fit ​​block is provided on the side wall of the extraction bowl 51, the snap-fit ​​block is snapped into the snap-fit ​​notch 413, and after the extraction bowl 51 is rotated, it is snapped into the snap-fit ​​groove 412. Thus, when assembling the extraction bowl 51, the snap-fit ​​block of the extraction bowl 51 can be aligned with the snap-fit ​​notch 413. After the extraction bowl 51 is snapped into the snap-fit ​​notch 413 upwards or downwards, it corresponds to the snap-fit ​​groove 412. Rotating the extraction bowl 51 will allow the snap-fit ​​block to snap into the snap-fit ​​groove 412, thereby assembling the extraction bowl 51 and the movable seat 41.

[0059] After the extraction process is completed, the extraction bowl 51 can be rotated so that the locking block aligns with the locking notch 413, and then the extraction bowl 51 can be removed for cleaning.

[0060] Based on this structure, the first connecting part includes a snap-fit ​​groove 412 and a snap-fit ​​notch 413, while the second connecting part includes a snap-fit ​​block. Of course, the first and second connecting parts can also be implemented using the existing technology of spring pins and pin holes in corresponding fit, or they can be implemented using internal and external thread assembly methods, depending on actual needs.

[0061] It should be noted that the coffee grinding assembly 20 in this embodiment uses a conventional coffee grinding structure, namely, a bean hopper and a burr structure. The bean hopper is located above the burr structure, and the powder outlet connects to the bottom of the burr structure. Thus, the burr rotates under the action of a motor, grinding the coffee beans that fall into the bean hopper, thereby achieving coffee powder grinding. The specific structure of this coffee grinding assembly 20 is not the subject of this application and will not be described in detail here.

[0062] Of course, the water outlet assembly 60 may include a water tank, a water pump, and a heating structure. The water pump can guide the water in the water tank to the heating structure for heating, and then guide it directly to the guide channel through the water outlet pipe 15 for coffee brewing. Alternatively, the water in the water tank can be directly guided to the water outlet pipe 15 for coffee brewing. In addition, the extraction assembly 50 may also be the extraction bowl 51 in the existing structure. An extraction filter can be installed in the extraction bowl 51 for coffee extraction. The specific structure will not be described in detail.

[0063] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
