Description

Technical Field

[0001] This invention relates to the field of coffee machine technology, and more particularly to a coffee machine brewing component and a coffee machine. Background Technology

[0002] In a coffee machine, during coffee brewing, the brewing plug on the machine corresponds to the brewing chamber. The brewing plug guides the water flow in the machine to brew the coffee grounds in the brewing chamber, thus achieving coffee extraction.

[0003] To facilitate cleaning of the brewing base after coffee brewing, the brewing stopper and brewing base of the coffee machine are designed to be movable. They can move in a straight line, allowing the brewing base and brewing stopper to be misaligned or aligned. Alternatively, they can rotate, causing the brewing base and brewing stopper to be misaligned or aligned during rotation. When aligned, coffee brewing occurs; when misaligned, cleaning of the brewing base is convenient. Since the brewing stopper needs to connect to the internal tubing of the coffee machine, the brewing base is movably connected to the machine, allowing for switching between different states through its movement.

[0004] In related technologies, the brewing stand is typically rotatably mounted on the coffee machine body. The brewing process is completed within the brewing stand by rotating it to disengage it from the coffee machine's brewing plug, allowing for easy cleaning. However, the brewing chamber of the brewing stand usually includes a tamper for tamping the coffee grounds and a drive structure that moves the tamper up and down to achieve the tamping action, thereby improving the flavor of the brewed coffee.

[0005] Therefore, cleaning the entire brewing base directly can easily damage the internal drive structure during the cleaning process. Furthermore, since the drive structure is usually connected to the main unit of the coffee machine, the brewing base cannot be completely removed from the machine, resulting in cleaning blind spots. Summary of the Invention

[0032] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] Example 1, See Figures 1-16 This invention discloses a coffee machine brewing assembly, including a brewing support 10 and a brewer 20. The brewing support 10 contains a drive chamber 11, a first drive member 30, and a linkage member 12. The first drive member 30 has a drive end and is mounted in the drive chamber 11. The linkage member 12 has a first end and a second end 121, the first end being connected to the drive end of the first drive member 30, and the second end 121 having a first connecting portion 1211.

[0034] The brewing device 20 includes a brewing chamber 23, a brewing outlet 24, a through-hole, a brewing net 22, and a pusher 21. The pusher 21 is movably installed in the brewing chamber 23. The brewing outlet 24 is connected to the top of the brewing chamber 23, and the through-hole is connected to the bottom of the brewing chamber 23. The pusher 21 has a push end 212 and a linkage end 211 that are opposite to each other. The brewing net 22 is installed on the push end 212. The linkage end 211 has a second connecting part that can extend out of the through-hole.

[0035] During assembly, the brewer 20 can be assembled onto the brewing support 10, and the second connecting part on the brewer 20 can correspond to the first connecting part 1211 on the brewing support 10, so that the second connecting part and the first connecting part 1211 are connected accordingly. In this way, the pusher 21 in the brewing chamber 23 can be connected to the first connecting part 1211 of the brewing support 10 through the second connecting part, so that the pusher 21 is linked with the linkage 12.

[0036] Based on the above structure, when using the brewing component of the coffee machine of the present invention, the brewing component can be assembled onto the coffee machine. During the coffee brewing operation, the brewing support 10 is first moved to the position of the powder guiding channel 70 of the coffee machine by the drive structure on the coffee machine. The powder guiding channel 70 can guide the coffee powder ground by the grinding system in the coffee machine to the brewing port 24 of the brewer 20, and then guide it into the brewing chamber 23 through the brewing port 24 for coffee brewing and extraction.

[0037] Subsequently, the brewing support 10 is moved by the drive structure on the coffee machine to move the brewing plug 50 of the coffee machine to perform the tamping and brewing action with the brewing plug 50 on the coffee machine. Alternatively, the tamper of the coffee machine can be moved separately to the brewing port 24 of the brewer 20 to tamp the coffee powder in the brewing chamber 23 before brewing and extraction.

[0038] After the coffee is brewed in the brewer 20, the brewing chamber 23 of the brewer 20 needs to be cleaned of coffee grounds. The first drive member 30 can be activated, and the drive end of the first drive member 30 drives the first end of the linkage member 12 to move toward the brewer 20. Since the second end 121 of the linkage member 12 is connected to the second connection part of the push member 21 in the brewing chamber 23 through the first connection part 1211, the linkage member 12 can drive the push member 21 to move toward the brewing port 24 under the drive of the first drive member 30. The push member 21 can push the coffee grounds on the brewing net 22 to the brewing port 24, which makes it convenient to clean the coffee grounds in the brewing chamber 23.

[0039] However, after the coffee extraction process is completed, coffee liquid and coffee powder may remain on the inner wall of the brewing chamber 23. Before the next coffee extraction, the brewer 20 needs to be cleaned separately. Since the pusher 21 inside the brewer 20 needs to be connected to the first drive 30 to complete the push operation, cleaning it directly may cause water to enter the first drive 30, affecting its normal use.

[0040] In this embodiment, the brewer 20 and the brewing support 10 are made detachable. The brewer 20 extends out of the through-hole linkage end 211 and is detached from the second connection part 1211 of the second end 121 of the linkage member 12 by the second connection part. In this way, the brewer 20 is completely detached from the brewing support 10. Since the first driving member 30 is located in the driving cavity 11 of the brewing support 10, when the brewer 20 is cleaned separately, there is no lubricating oil because there is no driving structure inside. The brewer 20 can be cleaned outside the coffee machine and placed in a dishwasher or other equipment for deep cleaning without affecting the coffee structure on the coffee machine.

[0041] Furthermore, when the brewer 20 is removed from the coffee machine or brewing stand 10 for cleaning, there are more cleaning angles, reducing the existence of cleaning dead spots, thus making the cleaning more comprehensive and cleaner.

[0042] As an optional implementation, the brewing support 10 may also be provided with a mounting groove 13 and a mounting port 16. The second end 121 of the linkage member 12 installed in the drive cavity 11 of the brewing support 10 extends through the drive cavity 11 to the mounting groove 13. The mounting port 16 is connected to the mounting groove 13. When the brewer 20 is assembled with the brewing support 10, the brewer 20 can be inserted into the mounting groove 13 through the mounting port 16. The second connecting part of the linkage end 211 of the push member 21 in the brewer 20 is detachably connected to the first connecting part 1211 in the mounting groove 13.

[0043] Based on this structure, after the brewer 20 is assembled to the brewing support 10, the outer periphery of the brewer 20 can be limited by the mounting groove 13, reducing the shaking of the brewer 20 during the tamping and brewing actions. At the same time, the second end 121 of the linkage 12 extending from the drive chamber 11 is linked with the linkage end 211 of the pusher 21 in the brewing chamber 23. When the linkage 12 of the first drive member 30 moves, it can link the pusher 21 in the brewing chamber 23 to push the coffee grounds.

[0044] Furthermore, during the pushing process, the brewer 20 is positioned by the mounting slot 13, so the assembly structure is more stable when coffee powder residue is pushed inside, and it is not easy to detach from the brewing support 10.

[0045] In some implementation structures, the mounting port 16 can be set on the side wall of the mounting groove 13. The brewer 20 can be inserted into or removed from the brewing support 10 through the side of the mounting port 16, preventing the brewer 20 from being removed from above and interfering with the powder guiding channel 70, the tamping structure, or the brewing plug 50 on the coffee machine, making it more convenient to put in and take out.

[0046] As an optional implementation, in order to ensure that the brewer 20 and the brewing support 10 maintain a more stable state after assembly for brewing, coffee powder residue and other actions, a first locking member is further provided on the brewer 20, and a second locking member is provided on the side wall of the mounting groove 13.

[0047] After the brewer 20 is inserted into the mounting slot 13 through the mounting port 16, the second connecting part on the brewer 20 is connected to the first connecting part 1211 of the brewing support 10 extending into the mounting slot 13. Then, the first locking member on the brewer 20 is connected to the second locking member for locking. In this way, the brewer 20 and the brewing support 10 are locked together by the first and second locking members. The brewer 20 and the brewing support 10 are not easy to loosen in the working state. In particular, the first connecting part 1211 can maintain a stable connection with the second connecting part and is not easy to separate. Therefore, the pushing operation in the brewing chamber 23 can be carried out stably, reducing the possibility of loosening due to external force.

[0048] As an optional implementation, the first locking member includes a locking buckle 25, and the second locking member includes a locking port 17. In this way, after the brewer 20 is installed into the mounting groove 13 through the mounting port 16, the locking port 17 of the brewer 20 corresponds to the locking port 17 provided in the mounting groove 13, so that the brewer 20 can be engaged with the locking port 17 by the locking buckle 25.

[0049] As an optional implementation, the locking buckle 25 includes a pressing section 252 and a buckle body 251. Specifically, a first elastic member 253 is provided between the pressing section 252 and the brewer 20. The first elastic member 253 is used to provide a first elastic stress to drive the buckle body 251 to engage with the locking port 17. The pressing section 252 is used to compress the first elastic member 253 when force is applied to drive the buckle body 251 to disengage from the locking port 17.

[0050] Since the locking buckle 25 is connected to the brewer 20 via the pressing section 252 and the first elastic member 253, under normal conditions, the elastic stress provided by the first elastic member 253 drives the pressing section 252 away from the brewer 20, and the buckle body 251 of the locking buckle 25 can also move away from the brewer 20 along with it.

[0051] When the brewer 20 is inserted into the mounting slot 13 through the mounting port 16, the pressing section 252 of the locking buckle 25 can be pressed manually. The pressing section 252 will be pressed to drive the buckle body 251 closer to the brewer 20, thus avoiding the mounting port 16. The brewer 20 can be smoothly placed into the mounting slot 13 of the brewing support 10. The buckle body 251 of the locking buckle 25 corresponds to the locking port 17 of the mounting slot 13. After that, the pressing section 252 is released, the first elastic component 253 is reset, and the buckle body 251 is driven to engage with the locking port 17.

[0052] When unlocking, the pressing section 252 of the locking buckle 25 is pressed manually. When the pressing section 252 is pressed, the buckle body 251 of the locking buckle 25 can be disengaged from the locking port 17, thus completing the unlocking action.

[0053] It should be noted that a pressing port can be further provided on the brewing support 10. This pressing port is located above or below the locking port 17. The user can press the port by pressing the pressing section 252 of the locking buckle 25.

[0054] Of course, in some other implementations, the first locking element can be a spring-loaded pin as in the prior art, and the corresponding second locking element can be a pin hole. Alternatively, the first locking element can be a magnetic structure, and the corresponding second locking element can be a magnet, so that positioning and locking can also be achieved through magnetic attraction. Or, both the first and second locking elements can be hooks or similar structures for locking.

[0055] As an optional implementation, the first connecting part 1211 includes a slot, and the corresponding second connecting part includes a locking block 2111. When the brewer 20 is installed into the mounting slot 13 through the mounting port 16, the locking block 2111 of the push member 21 in the brewer 20 can correspond to the slot in the mounting slot of the linkage member 12 extending into the mounting slot 13. During the installation of the brewer 20, the locking block 2111 can slide and engage with the slot, and the two can engage.

[0056] In this embodiment, the card block 2111 is connected or separated from the card slot by assembly. When assembling, the card block 2111 can be slid into the corresponding opening of the card slot and engaged. When separating, it can be slid out accordingly.

[0057] Compared to related technologies that use buckles or latches, or buckles connected to buckles, which require pressing or other actions to unlock, this method is much more convenient.

[0058] In some other implementation structures, the first connecting part 1211 and the second connecting part can also be selected as magnetic structures, so that the pusher 21 and the linkage 12 can be linked during assembly.

[0059] As an optional implementation, a first exhaust channel 214, a second exhaust channel 215, a sealing member 213, and a second elastic member 216 may also be provided at the push end 212 to cover the foaming net 22 at the push end 212.

[0060] Specifically, the first exhaust channel 214 extends axially along the pusher 21, and one end of the first exhaust channel 214 is provided with a first pressure relief port 2141, while the other end is provided with a first guide port. The aforementioned second elastic member 216 and sealing member 213 are both installed in the first exhaust channel 214, with the sealing member 213 located at the first pressure relief port 2141. The second elastic member 216 provides a second elastic stress to drive the sealing member 213 to seal the first pressure relief port 2141. The aforementioned second exhaust channel 215 extends radially along the pusher 21, and one end of the second exhaust channel 215 is provided with a second guide port, while the other end is provided with a second pressure relief port 2151. The second guide port and the first guide port, and the second pressure relief port 2151, extend to the outside of the brewing chamber 23.

[0061] Based on this structure, when the coffee machine's brewing plug 50 or tamper enters the brewing chamber 23 of the brewer 20 during the brewing or tamping action, in order to prevent coffee powder from flying or coffee liquid from overflowing during the action, the peripheral wall of the pusher 21 and the inner peripheral wall of the brewing chamber 23 need to maintain a sliding seal assembly, and the outer periphery of the brewing plug 50 can also maintain a seal with the brewing chamber 23 when it enters the brewing chamber 23.

[0062] Therefore, a certain amount of air space is required inside the brewing chamber 23 to prevent excessive air pressure inside the brewing chamber 23 from causing problems with the brewing action or the powder pressing action.

[0063] During tamping, the brewing stopper 50 presses the coffee powder into contact with the brewing net 22. The gas pressure during tamping pushes against the sealing member 213, causing the second elastic component 216 to compress. This opens the first pressure relief port 2141 of the sealing member 213, allowing internal gas to be guided through the first exhaust channel 214 into the second exhaust channel 215's second outlet, and then discharged through the second pressure relief port 2151 of the second exhaust channel 215. This process keeps the coffee powder adhered to the brewing net 22, ensuring even compaction and close contact. During brewing, the compacted coffee puck firmly adheres to the brewing net 22, preventing most fine powder from leaking out, resulting in a clear coffee liquid and improved extraction.

[0064] Of course, when no venting is performed internally, the sealing member 213 can remain sealed to the first pressure relief port 2141 under the action of the second elastic member 216, reducing the possibility of coffee powder or coffee liquid spilling out.

[0065] Furthermore, since the exhaust path is formed by combining the first exhaust channel 214 in the axial direction and the second exhaust channel 215 in the radial direction, the pressure relief inlet is set along the first exhaust channel 214 in the tamping direction, and the pressure relief outlet is set along the second exhaust channel 215, which reduces the spillage of coffee powder during the pressure relief process.

[0066] It should also be noted that sealing rings 217 can be provided on both the upper and lower outer peripheral walls of the pusher 21, and the position between the two sealing rings 217 on both sides of the second pressure relief port 2151 is also noted.

[0067] As an optional implementation, a guide rod 18 can also be provided in the brewing support 10. A guide channel 181 is provided in the guide rod 18. One end of the guide channel 181 is connected to the second pressure relief port 2151. After the brewer 20 is assembled into the mounting groove 13 of the brewing support 10, the second pressure relief port 2151 of the brewer 20 can correspond to the guide channel 181 of the guide rod 18 on the brewing support 10 to guide the internal gas out.

[0068] As an optional implementation, the coffee machine brewing assembly also includes a mounting bracket 40 and a brewing plug 50. The brewing plug 50 can move closer to or further away from the brewer 20 under the action of the brewing plug drive 51 of the coffee machine, and a pipe structure that communicates with the internal water circuit of the coffee machine can be provided inside the brewing plug 50.

[0069] Specifically, the mounting bracket 40 is provided with a second driving member 60, a first position, and a second position. The brewing support 10 is rotatably mounted on the mounting bracket 40 and swings between the first position and the second position under the drive of the second driving member 60. The brewing plug 50 is located in the first position. When the brewing support 10 swings to the first position, the brewing plug 50 corresponds to and passes through the brewing port 24.

[0070] See Figure 11 as well as Figure 13 At this time, the coffee is in the brewing and powder receiving state. The brewing support 10 is in the second position of the mounting bracket 40. The coffee machine's powder guiding channel 70 extends to the second position of the mounting bracket 40. At this time, the powder guiding channel 70 can guide the coffee beans ground by the coffee machine's grinding system into the brewer 20 and into the brewing chamber 23 through the brewing port 24.

[0071] See Figure 14 After the powder receiving action is completed, the second driving member 60 drives the brewing support 10 to swing relative to the mounting bracket 40, so that the brewing support 10 swings to the first position on the mounting bracket 40. At this time, the brewing port 24 of the brewer 20 installed on the brewing support 10 is connected to the brewing plug 50. The brewing plug 50 can be driven by the brewing plug driving member 51 to move toward the brewing port 24, so that the brewing plug 50 compacts the coffee powder in the brewing chamber 23.

[0072] The brewing tube built into the brewing plug 50 can guide the brewing water in the coffee machine to brew the coffee powder in the brewing chamber 23. After being pressed down and compacted, the coffee powder eliminates the loose gaps, and the entire coffee powder puck fits completely against the bottom brewing net 22. This reduces the occurrence of local suspension of the coffee powder puck and uneven thickness of the powder layer. In addition, the water flow cannot short-circuit through the gaps on the side of the puck, and the water flow is forced to penetrate the coffee powder vertically, without breaking or leaking powder, thus improving the taste of coffee extraction.

[0073] See Figure 15 After the coffee extraction is completed, the first drive component 30 in the brewing support 10 is activated. The first drive component 30 drives the first end of the linkage component 12 to move toward the brewer 20. The second end 121 of the linkage component 12 can then drive the push component 21 in the brewer 20 to move toward the brewing port 24, directly pushing out the brewed coffee grounds on the brewing net 22, reducing clogging of the brewing net 22 and fine powder residue.

[0074] Specifically, guide plates 14 can be provided on both sides of the brewing support 10. After the brewer 20 is assembled into the mounting slot 13 of the brewing support 10, the guide plates 14 can be connected to the side of the brewing port 24 of the brewer 20. In this way, after the coffee grounds reach the brewing port 24, they can be directly guided out to the residue bin on the coffee machine by the guide plates 14 for centralized processing of the coffee grounds.

[0075] Furthermore, in some implementations, a guide rod 18 is provided on the brewing support 10, with the guide channel 181 of the guide rod 18 communicating with the second pressure relief port 2151 of the brewer 20 for venting and pressure relief. Alternatively, a guide groove can be provided on the mounting bracket 40, with the extension direction of the guide groove aligned with the swing direction of the brewing support 10. The guide rod 18 slides within the guide groove, guiding the brewing support 10 to perform limited swinging, while the two end walls of the guide groove can correspond to the brewing support 10 swinging to the first and second positions.

[0076] As an optional implementation, a transmission sleeve 15 can be provided on the brewing support 10, and a transmission through hole can be provided on the mounting bracket 40, so that the transmission sleeve 15 can be rotatably connected to the transmission through hole.

[0077] Specifically, the first driving component 30 includes a first motor 33, a first gear 31, and a rack 32. The first motor 33 is mounted on the mounting bracket 40. The shaft of the first motor 33 extends into the driving cavity 11 via the transmission sleeve 15 and is connected to the first gear 31. The rack 32 is mounted in the driving cavity 11 and meshes with the first gear 31. The rack 32 is connected to the first end. The second driving component 60 is used to drive the transmission sleeve 15 to rotate.

[0078] Based on this structure, when the brewing support 10 swings as a whole, the transmission sleeve 15 of the brewing support 10 can be driven by the second drive member 60 to swing relative to the transmission through hole of the mounting bracket 40. When the coffee powder residue in the brewer 20 is pushed, the shaft of the first motor 33 can rotate in the transmission sleeve 15 to guide the first gear 31, which is connected to the shaft of the first motor 33, to rotate. The rotation of the first gear 31 can drive the rack 32 that meshes with it to move up and down, thereby realizing the pushing action of the pusher 21.

[0079] Since the pusher 21 is controlled by meshing, the meshing transmission can accurately control the movement stroke of the pusher 21. At the same time, the first motor 33 shaft of the first drive member 30 is guided by the transmission sleeve 15 to drive the first gear 31 to rotate, so that the first gear 31 and the shaft of the first motor 33 keep rotating coaxially, thus improving the driving accuracy of the rotation of the first motor 33.

[0080] Furthermore, since the rotating shaft of the first motor 33 is set relative to the rotating base of the mounting bracket 40 via the brewing support 10, the rotating base of the second drive component 60 can be used as the assembly base of the first drive component 30, thereby improving the space utilization of the overall structure and reducing the problem of large assembly space caused by the setting of two sets of drives.

[0081] As an optional implementation, the first driving component 30 further includes a transmission shaft 34, a first transmission gear 35, and a second transmission gear. The first transmission gear 35 is disposed at one end of the transmission shaft 34, and the other end of the transmission shaft 34 extends into the driving cavity 11 via the transmission sleeve 15 and is connected to the first gear 31. The second transmission gear is connected to the rotating shaft of the first motor 33 and meshes with the first transmission gear 35. Thus, the rotation of the first motor 33 can drive the second transmission gear to rotate, and the rotation of the second transmission gear can drive the first transmission gear 35 to rotate. The rotation of the first transmission gear 35 can drive the transmission shaft 34 to rotate, and the rotation of the transmission shaft 34 can then drive the first gear 31, thereby realizing the linkage of the rack 32 with the aforementioned linkage component 12, and then linkage with the push component 21 to perform a pushing operation. In this way, the entire driving structure uses gears to drive the transmission shaft 34, and then the transmission shaft 34 links the internal gears and the rack 32, improving the stability of the entire driving structure.

[0082] As an optional implementation, a limit switch is provided on the mounting bracket 40, and a limit part is provided on the first transmission tooth 35. The limit part is used to contact the limit switch. Specifically, the limit part can be implemented by a limit block, a limit rod, or a limit piece, etc. The limit switch is provided on the rotation path of the first transmission tooth 35. When the pushing action of the pusher 21 is completed, the first transmission tooth 35 rotates to the limit part and can just contact the limit switch. At this time, the first motor 33 is stopped to prevent the pusher 21 from being completely pushed out of the brewing chamber 23.

[0083] As an optional implementation, the second driving component 60 includes a second motor 61, a transmission base 62, a third transmission gear 63, and a fourth transmission gear 64. The transmission base 62 is provided with a positioning bushing 621, which is rotatably inserted through the transmission hole and fitted onto the outside of the transmission sleeve 15. The outer periphery of the transmission base 62 is provided with the third transmission gear 63, and the fourth transmission gear 64 is connected to the rotating shaft of the second motor 61 and meshes with the third transmission gear 63.

[0084] That is, when the brewing support 10 is rotated, the second motor 61 drives the transmission seat 62 to rotate the fourth transmission gear 64. The fourth transmission gear 64 is linked with the third transmission gear 63, which in turn drives the transmission seat 62 to rotate. The transmission seat 62 is connected to the transmission sleeve 15 of the brewing support 10 through the positioning bushing 621, so it can drive the brewing support 10 to swing stably.

[0085] The transmission seat 62 is fitted with the transmission sleeve 15 of the brewing support 10 through the positioning bushing 621 to achieve coaxial assembly, thereby reducing the wobble problem that occurs during rotation.

[0086] As an optional implementation, a positioning protrusion 6211 is provided inside the positioning bushing 621; a positioning groove 151 is provided outside the transmission sleeve 15; the positioning groove 151 and the positioning protrusion 6211 are inserted into each other to limit the relative rotation of the positioning bushing 621 and the transmission sleeve 15, thereby effectively preventing the brewing support 10 from slipping due to relative rotation, making its movement to the first position or the second position more accurate, and preventing position deviation caused by the relative rotation of the brewing support 10 and the positioning bushing 621.
