Description

Technical Field

[0001] This application relates to the field of coffee machine technology, and in particular to a driving mechanism for a brewing component and a coffee machine. Background Technology

[0002] After coffee extraction, the brewing unit of a coffee machine ejects coffee grounds from the brewing cup for cleaning. This ejection mechanism needs to be reset to the bottom of the brewing cup by a drive mechanism for subsequent use. In existing technology, the drive mechanism uses rigid transmission to provide the reset power. While this ensures accurate trajectory, it requires overcoming the resistance of the coffee grounds and the weight of the components, resulting in concentrated motor load. Furthermore, when the coffee grounds are damp and clumpy, they are prone to jamming and cause significant reset impact. Utility Model Content

[0003] The purpose of this application is to provide a driving mechanism for a brewing component and a coffee machine.

[0004] The embodiments of this application adopt the following technical solution: a driving mechanism for a brewing component, applied to a coffee machine, the brewing component includes a brewing cup and a connecting rod, one end of the connecting rod extending from the bottom of the brewing cup into the inside of the brewing cup; The drive mechanism includes: A drive component, which is connected to the brewing component and drives the brewing component to move; A first reset mechanism is connected to the drive assembly and provides a first reset force to the connecting rod when the brewing assembly is reset. The second reset mechanism includes an elastic reset member disposed on the connecting rod, and the second reset mechanism provides a second reset force to the connecting rod when the brewing assembly is reset.

[0005] By cooperating with the first reset component and the second reset component, after the connecting rod pushes out the coffee grounds in the brewing cup, a reset force is applied to the connecting rod so that the connecting rod can be accurately, smoothly and stably reset.

[0006] In some embodiments, the first reset mechanism includes a reset gear and a reset lever connected to the reset gear. The reset gear is connected to the drive assembly and drives the reset lever to rotate under the drive of the drive assembly. The drive assembly includes a drive motor, a worm gear, a push rod, and a rack; The drive motor is connected to one end of the worm gear and drives the worm gear to rotate. One end of the push rod is threaded into the worm gear, and the worm gear rotates to drive the push rod to move up and down. The brewing cup is movably connected to the push rod and moves under the pushing action of the push rod; One end of the rack is connected to the push rod, and the other end of the rack extends downward. The rack engages with a reset gear mounted on the frame of the coffee machine.

[0007] In some embodiments, a limiting platform is provided at the lower end of the connecting rod; The elastic reset component is a pull rod spring, which is sleeved on the connecting pull rod. The top of the pull rod spring abuts against the bottom of the brewing cup, and the bottom of the pull rod spring abuts against the limiting platform.

[0008] In some embodiments, the coffee machine frame has a sliding track, which includes a horizontal portion and a vertical portion that are interconnected. After the brewing cup receives coffee grounds, the drive assembly rotates forward to drive the brewing assembly to slide horizontally along the first direction of the horizontal portion and upward along the vertical portion to tamp the coffee grounds for brewing. After brewing, the drive assembly reverses to drive the brewing cup to move downward relative to the connecting rod to push out the coffee grounds. After the coffee grounds are pushed out, the drive assembly drives the brewing assembly to slide back to its original position along the second direction of the horizontal portion, where the first direction is different from the second direction.

[0009] In some embodiments, the drive mechanism further includes a locking block movably disposed on the frame, the locking block having a limiting top surface. During the upward movement of the brewing assembly, the connecting rod pushes the locking block to flip upward and reset. When the brewing assembly moves downward until the bottom of the connecting rod contacts the limiting top surface, the limiting top surface blocks the connecting rod from moving downward, and the brewing cup moves downward relative to the connecting rod.

[0010] In some embodiments, the limiting top surface is a plane, and when the brewing cup slides along the second direction of the horizontal portion, the bottom of the connecting rod moves along the limiting top surface.

[0011] In some embodiments, the frame is provided with a guide rail that engages with the other end of the reset lever. The reset lever moves along the initial end of the guide rail to the terminal end under the forward rotation of the reset gear. The terminal end has a latch for securing the reset lever.

[0012] In some embodiments, the reset lever is provided with a pressure rod; when the brewing assembly is reset, the reset lever rotates in the opposite direction from the terminal, causing the pressure rod to contact the connecting rod, and the pressure rod applies a downward first reset force to the connecting rod.

[0013] In some embodiments, the connecting rod has a pressure-bearing platform, and when the brewing assembly is reset, the pressure rod rotates from above the pressure-bearing platform onto the pressure-bearing platform.

[0014] This application also provides a coffee machine, including a brewing assembly and a frame, and further including a drive mechanism as described in any of the above embodiments, the drive mechanism being used to provide a reset force to the connecting rod in the brewing assembly.

Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0030] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0031] To address the problems in the background art, this application provides a driving mechanism for a brewing assembly, applied to a coffee machine. The brewing assembly can be used for coffee extraction. It includes a brewing cup 1 and a connecting rod 2. One end of the connecting rod 2 extends from the bottom of the brewing cup 1 into the cup 1, allowing coffee grounds to be placed inside. After coffee extraction is complete, the brewing cup 1 and the connecting rod 2 can move relative to each other, causing the connecting rod 2 to move upwards relative to the brewing cup 1, pushing out the coffee grounds. These grounds can then be scraped out using a scraper or similar structure.

[0032] Combination Figures 1 to 3The drive mechanism provided in this application may include a drive component, a first reset mechanism, and a second reset mechanism.

[0033] The driving component is connected to the brewing component and drives its movement. For example, the driving component can move the brewing component to the brewing head position after receiving coffee powder, and the brewing head pours hot or ice water into the brewing cup 1 to extract the coffee. After the coffee extraction is complete, the driving component can also drive the brewing component back to the powder receiving position to reset. This involves the first and second reset mechanisms resetting the connecting rod 2 of the brewing component. Coffee powder can fall into the brewing cup 1 through the downward-sloping powder receiving channel 3. A sealing ring 4 can be installed on the top of the connecting rod 2 to ensure a tight connection between the connecting rod 2 and the brewing cup 1, preventing coffee leakage.

[0034] The first reset mechanism is connected to the drive assembly and provides a first reset force to the connecting rod 2 when the brewing assembly resets. That is, the drive assembly can provide a driving force not only to the brewing assembly but also to the first reset mechanism. For example, the drive assembly can be driven by a single drive motor, reducing the number of power source components in the drive assembly. The first reset mechanism can provide a rigid reset action to the connecting rod 2 to ensure the accuracy of its reset.

[0035] The second reset mechanism may include an elastic reset member 5 disposed on the connecting rod 2. The second reset mechanism provides a second reset force to the connecting rod 2 when the brewing assembly resets. Specifically, when the brewing cup 1 moves downward relative to the connecting rod 2, the connecting rod 2 pushes out the coffee grounds inside the brewing cup 1, causing the brewing cup 1 to compress and store energy in the elastic reset member 5. Once the coffee grounds have been completely pushed out, the first reset mechanism applies a downward first reset force to the connecting rod 2. The elastic reset member 5 extends and releases its stored energy to provide a downward second reset force to the connecting rod 2. The elastic reset member 5 and the first reset mechanism work together to push the connecting rod 2 downward, causing the connecting rod 2 to move and reset.

[0036] The second reset force can be understood as an elastic force. This elastic force works in conjunction with the rigid reset force provided by the first reset mechanism to construct a dynamic coupling mechanism. This ensures the accurate reset trajectory of the connecting rod 2 through the first reset mechanism, while the elastic force of the elastic reset component 5 reduces the load on the first reset mechanism. This prevents rapid wear of some structural components in the first reset mechanism and also avoids elastic attenuation of the elastic reset component 5. The slag pushing action is coupled with the energy storage process of the elastic reset component 5, allowing energy storage to be completed simultaneously during slag pushing. The storage of spring potential energy requires no additional power or action, simplifying the complex structure of traditional independent energy storage mechanisms and ensuring that the spring can release energy instantly during reset, forming an instantaneous resultant force with the lever's driving force. This solves the defects of simple superposition schemes such as dynamic conflict and structural redundancy; utilizing the elastic buffering characteristics of the elastic reset component 5, it absorbs the resistance fluctuations of powder and slag within the brewing cup 1, avoiding rigid jamming and reducing reset impact.

[0037] In this embodiment, the first reset component and the second reset component can work together to apply a reset force to the connecting rod 2 after the connecting rod 2 pushes out the coffee grounds in the brewing cup 1, so that the connecting rod 2 can be accurately and smoothly reset stably.

[0038] In some embodiments, the first reset mechanism may include a reset gear 6 and a reset lever 7 connected to the reset gear 6. The reset gear 6 is connected to a drive assembly and drives the reset lever 7 to rotate under the drive of the drive assembly. The reset gear 6 may be mounted on the frame 8 of the coffee machine. The reset gear 6 can engage with the rack 11 in the drive assembly (described below) and rotate (forward and reverse) under the drive of the rack 11. One end of the reset lever 7 may be a gear-shaped structure, and the teeth of the gear-shaped structure can mesh externally with the reset gear 6. When the reset gear 6 rotates, it can drive the reset lever 7 to rotate synchronously. When the brewing assembly moves from the powder receiving position to the brewing position, the reset lever 7 can rotate upward. When the brewing assembly resets, the reset lever 7 can rotate downward to apply a downward second reset force to the connecting rod 2.

[0039] The drive assembly may include a drive motor (not shown in the figure), a worm gear 9, a push rod 10, and a rack 11.

[0040] The worm 9 can be arranged vertically, and the drive motor can be connected to one end of the worm 9 through a gear set to drive the worm 9 to rotate.

[0041] One end of the push rod 10 can be provided with a bushing 12 that is threaded with the worm 9. When the worm 9 rotates, it can drive the bushing 12 to move up and down along the axial direction of the worm 9, thereby realizing the up and down movement of the push rod 10.

[0042] The brewing cup 1 is movably connected to the push rod 10 and moves under the push of the push rod 10.

[0043] One end of the rack 11 is connected to the push rod 10, and the other end of the rack 11 can extend downwards. As the push rod 10 moves up and down, the rack 11 also moves up and down synchronously. The rack 11 engages with the reset gear 6 mounted on the frame 8 of the coffee machine, thus driving the reset gear 6 to rotate as the rack 11 moves up and down. The rack 11 can maintain its engagement with the reset gear 6 at all times. However, it is understandable that when the rack 11 moves upwards to a certain height, the engagement between the rack 11 and the reset gear 6 can be disengaged. When the rack 11 moves downwards, it can re-establish its engagement with the reset gear 6, thereby driving the reset gear 6 to rotate in the opposite direction, which in turn drives the reset lever 7 to rotate in the opposite direction, providing a rigid first reset force to the connecting lever 2, ensuring the precise reset of the connecting lever 2.

[0044] In some embodiments, a limiting platform 21 may be provided at the lower end of the connecting rod 2.

[0045] The elastic reset component 5 can be a pull rod spring, which can be fitted onto the connecting pull rod 2. The top of the pull rod spring can abut against the bottom of the brewing cup 1, and the bottom of the pull rod spring abuts against the limiting platform 21. In the powder receiving position, the pull rod spring can be in a slightly compressed state, i.e., a pre-tightened state. This pre-tightening of the spring provides an anti-loosening guarantee, reducing liquid leakage channels caused by component gaps. After brewing, the connecting pull rod 2 and the spring continue to maintain pre-tightness, preventing residual coffee dripping and the risk of component corrosion. For users, the enhanced sealing performance completely solves the pain points of coffee spillage soiling the machine and being difficult to clean, eliminating the need for frequent wiping and maintenance. During the process of the connecting pull rod 2 pushing out the coffee grounds in the brewing cup 1, the pull rod spring is compressed downwards by the brewing process, storing energy in the process. After the coffee grounds are ejected, as the brewing assembly moves towards the grounds receiving position, the reset lever 7 provides a rigid first reset force to the connecting rod 2. Simultaneously, the lever spring extends to release its elastic potential energy, providing a second reset force to the connecting rod 2. When the brewing cup 1 returns to its initial grounds receiving position, the connecting rod 2 fully resets, the lever spring returns to its pre-tensioned state, and the device enters the next cycle standby state.

[0046] In some embodiments, the coffee machine frame 8 has a sliding rail 13, which may include a horizontal portion and a vertical portion that are interconnected. After the brewing cup 1 is filled with coffee grounds, the drive assembly rotates forward, causing the brewing assembly to slide horizontally along the first direction of the horizontal portion and upward along the vertical portion to tamp the coffee grounds for brewing. After brewing, the drive assembly reverses, causing the brewing cup 1 to move downward relative to the connecting rod 2 to push out the coffee grounds. After the coffee grounds are pushed out, the drive assembly causes the brewing assembly to slide back to its original position along the second direction of the horizontal portion, which is different from the first direction. When the brewing assembly is back to its original position, the bottom of the connecting rod 2 is limited by a limiting mechanism during the sliding of the brewing assembly along the horizontal portion and during the pushing out of the coffee grounds.

[0047] The drive mechanism also includes a limiting mechanism movably mounted on the frame 8. This limiting mechanism may include a locking block 14, which has a limiting top surface. During the upward movement of the brewing component, the connecting rod 2 pushes the locking block 14 to flip upwards and reset. Here, the reset of the locking block 14 means that it can autonomously reset itself as the connecting rod 2 moves upwards. For example, the locking block 14 can be movably mounted on the frame 8 via a torsion spring. When the connecting rod 2 pushes the locking block 14 upwards, the torsion spring compresses; when the connecting rod 2 disengages from the locking block 14, the torsion spring extends, causing the locking block 14 to reset. After resetting, the locking block 14 can be locked in position by the torsion spring, or by other structures mounted on the frame 8, preventing it from continuing to flip downwards. For example, a stop can be provided on the frame 8 to restrict the downward flipping of the locking block 14. The top surface of the stop can be coplanar with the limiting top surface of the locking block 14, thus limiting the connecting rod 2.

[0048] The brewing assembly moves downward until the bottom of the connecting rod 2 contacts the limiting top surface. The limiting top surface blocks the connecting rod 2 from moving downward, thus acting as a limit. As the drive assembly drives, the brewing cup 1 continues to move downward. At this time, the connecting rod 2 is limited by the limiting top surface and cannot move downward. The brewing cup 1 moves downward relative to the connecting rod 2, and the connecting rod 2 moves upward relative to the brewing cup 1 to push the coffee grounds.

[0049] The limiting top surface is flat. When the brewing cup 1 slides along the second direction of the horizontal part, the bottom of the connecting rod 2 moves along the limiting top surface. The locking block 14 may also have a downwardly extending inclined surface. During the resetting process of the connecting rod 2, the connecting rod 2 can move from the limiting plane to the inclined surface. The rod spring slowly rebounds and releases elastic potential energy, driving the connecting rod 2 to move smoothly from high to low. Finally, the connecting rod 2 is fully reset, the brewing cup 1 returns to the powder receiving position, and the entire mechanism returns to the ready-to-work state, preparing for the next coffee brewing process. In addition, the above-mentioned inclined surface can also be set on the stop block as needed.

[0050] The push rod 10 may be provided with a moving channel 101, through which the push rod 10 pushes the brewing cup 1 to move along the sliding track 13 and the moving channel 101. For example, the push rod 10 may be inclined, and the moving channel 101 may also be inclined, with the moving channel 101 having a certain angle with both the horizontal and vertical parts.

[0051] When push rod 10 moves upward, brewing cup 1 can move downward along moving channel 101, and push rod 10 pushes brewing cup 1 to move horizontally in the horizontal part. Subsequently, brewing cup 1 can continue to move downward along moving channel 101, driving brewing cup 1 to move upward along the vertical part, so that the entire brewing process of brewing cup 1 can be driven by one drive motor driving push rod 10 through the drive mechanism, reducing the number of structural components in the drive device.

[0052] Specifically, the working principle of this drive mechanism can be summarized as follows: Initial Stage: After the brewing cup 1 has collected the powder at one end of the horizontal section in the initial position, the drive assembly is activated. The drive motor drives the worm gear 9 to rotate via the gear set, which in turn drives the push rod 10 to move upward. The upward movement of the push rod 10 can simultaneously achieve the following two linkages: First, it pushes the brewing cup 1 to move horizontally backward along the horizontal section, and then converts it to vertical upward movement along the vertical section. Second, it drives the rack 11 to move upward synchronously, and through the meshing transmission with the reset gear 6, it drives the reset lever 7 to rotate upward.

[0053] Pressing and brewing stages: combined Figures 4 to 6 The push rod 10 continuously drives the brewing cup 1 to rise vertically, and the connecting rod 2 rises synchronously with the brewing cup 1, passing through the locking block 14 from bottom to top. After the connecting rod 2 has completely passed through, the locking block 14 automatically returns to its original position under the elastic restoring force of the torsion spring. The brewing cup 1 continues to rise until it is in contact with the brewing head, completing the coffee powder compaction and hot (or cold) water brewing process.

[0054] Slag-pushing energy storage stage: combined with Figures 7 to 8 After brewing, the drive component performs a reverse action. The push rod 10 drives the brewing cup 1 to move vertically downward. The lower end of the connecting rod 2 contacts the locking end of the locking block 14. Because the position of the locking block 14 is locked, the brewing cup 1 continues to move downward, forcing the connecting rod 2 to extend upward relative to the brewing cup 1, pushing the coffee grounds out of the brewing cup 1. The coffee grounds can be discharged to the collection device (not shown in the figure). During this process, the connecting rod 2 synchronously compresses the rod spring, converting mechanical energy into elastic potential energy for storage, and reserving auxiliary power for subsequent reset.

[0055] Reset phase: Combining Figures 9 to 11After the slag is pushed out, the brewing cup 1 enters the reset process. The push rod 10 drives the brewing cup 1 to move horizontally forward along the sliding track 13 (resetting to the initial powder receiving position), while simultaneously driving the rack 11 downward. The rack 11 drives the reset gear 6 to rotate in the opposite direction, causing the end of the reset lever 7 to contact the lower end of the connecting rod 2 and apply downward pressure (the first reset force). At this time, the pull rod spring synchronously releases its elastic potential energy, forming a synergistic force with the downward pressure of the reset lever 7, jointly driving the connecting rod 2 to reset downward relative to the brewing cup 1. When the brewing cup 1 returns to the initial powder receiving position, the connecting rod 2 is fully reset, the pull rod spring returns to its pre-tensioned state, and the device enters the next cycle standby state.

[0056] In some embodiments, the frame 8 is provided with a guide rail 15 that engages with the other end of the reset lever 7. Driven by the forward rotation of the reset gear 6, the reset lever 7 moves along the guide rail 15 from its initial end to its final end. The final end has a locking slot 151 for securing the reset lever 7. The guide rail 15 allows the reset lever 7 to rotate more stably. Furthermore, the locking slot 151 at the end of the guide rail 15 can limit the reset lever 7 to its final position, preventing it from flipping downwards and interfering with subsequent powder pressing operations.

[0057] In some embodiments, the reset lever 7 may also be provided with a pressure rod 71, and the connecting rod 2 may also have a pressure-bearing platform 22, and the pressure rod 71 may pass through the guide rail 15 and contact the pressure-bearing platform 22.

[0058] When the brewing component is reset, the reset lever 7 rotates in the opposite direction from the terminal, causing the pressure lever 71 to rotate from above the pressure platform 22 to onto the pressure platform 22, and the pressure lever 71 applies a downward first reset force to the pressure platform 22.

[0059] This application also provides a coffee machine, including a brewing assembly and a frame 8, and a drive mechanism as described in any of the above embodiments, the drive mechanism being used to provide a reset force to the connecting rod 2 in the brewing assembly.

[0060] The foregoing has described in detail several embodiments of this application, but this application is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of this application, and all such variations and modifications should fall within the scope of protection claimed in this application.
