Description

Technical Field

[0001] This application belongs to the field of beverage brewing technology, and particularly relates to a reset component for a brewing device and a brewing device. Background Technology

[0002] In existing technologies, the coffee brewing and residue handling process is generally as follows: After brewing, the grounds pusher assembly, driven by a multi-stage transmission mechanism including gears and connecting rods, pushes the grounds out of the brewing chamber; then, the scraper blade on the outside of the brewing chamber slides against the surface of the grounds pusher assembly with the help of the elastic pressure of the torsion spring, scraping the remaining grounds into the grounds collection tray below, completing the initial cleaning of the residue; finally, the grounds pusher assembly needs to reverse its movement again through a complex transmission chain (including additional reset motors, cams, and other components), returning to the initial low position at the bottom of the brewing chamber, preparing for the next brewing process.

[0003] The reset mechanism of existing coffee machine coffee maker coffee grounds pushing components suffers from two prominent problems: First, the reset action relies on numerous additional and precise transmission components. For example, some models require independent miniature reset motors, reduction gear sets, and position sensors to achieve accurate reset. These components not only occupy a significant amount of internal space, making it difficult to miniaturize the overall machine, but also significantly increase material costs, assembly time, and the difficulty of subsequent maintenance. Second, due to the numerous transmission links, processing errors and assembly gaps of each component can easily accumulate, making it difficult to achieve a high degree of coordination during the reset of the coffee grounds pushing component. This can result in sluggish movement and abnormal noises, or even coffee grounds remaining due to component jamming, or even malfunctions where the coffee grounds pushing component cannot return to its original position, seriously affecting the user experience and product reliability. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide a reset component with simple structure, low cost and less prone to jamming, and a brewing device having the reset component.

[0005] The technical solution adopted in this application embodiment is a reset component for a brewing device. The brewing device includes a housing, a driving component, a brewing container, and a push rod with one end extending into the brewing container. The push rod is capable of moving up and down relative to the brewing container and has an initial low position and a slag-pushing high position. The reset component includes: A toggle component, which is rotatably mounted on the housing; A limiting component is provided on the housing and is used to stop and limit the push rod when the brewing container finishes brewing and moves downward, so that the push rod moves upward relative to the brewing container from the initial low position to the slag pushing high position, and pushes the powder and slag in the brewing container out of the brewing container. A transmission component is connected to the driving component and reciprocates in the vertical direction under the driving action of the driving component. When the transmission component reciprocates in the vertical direction, it pushes the actuating component to rotate reciprocally from the high position to the low position and from the low position to the high position. When the actuating component rotates from the high position to the low position, it pushes against the top rod, causing the top rod, which has been released from the limit by the limiting component, to move downward from the high position of the slag pusher and reset to the initial low position.

[0006] In an optional embodiment, the housing is provided with an arc-shaped guide rail; The actuating component includes a main body and a lever, one end of which is connected to the main body and the other end passes through the arc-shaped guide rail; When the transmission component moves downward, it abuts against the main body, causing the main body to move the lever from the high end of the arc-shaped guide rail to the low end. During the movement of the lever, it actuates the push rod, applying at least a downward force to the push rod, causing it to return from the high position of the slag pusher to its initial low position. With the help of the arc-shaped guide rail on the housing and the lever passing through it, the actuating component moves along a predetermined trajectory to precisely act on the push rod, achieving the return of the push rod from the high position of the slag pusher to its initial low position.

[0007] In an optional embodiment, the main body is arm-shaped, one end of the main body is rotatably connected to the housing, the main body has a first surface facing the housing and a second surface facing away from the housing, and one end of the lever is connected to the first surface of the other end of the main body; The transmission component includes a pushing part. When the transmission component moves downward, the pushing part abuts against the upper end face of the main body and pushes the main body to rotate downward. When the main body rotates, it drives the lever to move along the arc-shaped guide rail. The structure is reasonable, and the power transmission is stable and reliable.

[0008] In an optional embodiment, the lower end face of the pushing part of the transmission member protrudes downward and forms a hook. When the pushing part pushes the main body to rotate downward until the lever is at the lower end of the arc-shaped guide rail, the hook moves to the lower part of the main body. When the transmission member moves upward to reset, the hook drives the main body and the lever to reset upward, causing the lever to reset to the upper end of the arc-shaped guide rail. By providing a hook on the pushing part, the reset of the actuating member is achieved.

[0009] In an optional embodiment, the convex arc surface near the high end of the arc-shaped guide rail partially contracts inward to form a limiting portion. A branch groove is provided on the outer side of the convex arc surface of the arc-shaped guide rail between the limiting portion and the high end. One end of the branch groove connects to the convex arc surface near and below the limiting portion. The width of the limiting portion is smaller than the outer diameter of the lever. Under external force, the lever can deform the limiting portion to pass through it and be confined at the high end of the arc-shaped guide rail. Through the cooperation of the limiting portion and the branch groove, the lever can be held at the high end of the arc-shaped guide rail and will not move towards the low end under gravity.

[0010] In an optional embodiment, the driving component includes a motor; The transmission component includes a screw, a screw sleeve, and a pressure block. The screw is vertically positioned and connected to the motor, which drives the screw to rotate both counterclockwise and clockwise. The screw sleeve is threaded onto the screw and reciprocates up and down along the screw as it rotates. The lower end of the pressure block forms the pushing part. The transmission component has a simple and reasonable structure, provides smooth and effective power transmission, and avoids jamming.

[0011] In an optional embodiment, the limiting member includes a fixing member, a locking member, and a resetting member. The fixing member is fixed to the housing, the locking member is rotatably disposed on the housing, and the locking member has a first state of abutting against the fixing member and a second state of being separated from the locking member. The resetting member is disposed between the locking member and the housing and is used to apply a force to the locking member to keep it in the first state. The bottom of the push rod is provided with a protruding post, the axial direction of which is perpendicular to the axial direction of the push rod. When the brewing container moves towards the brewing head of the brewing device after receiving the powder, the protruding post can push the locking member, causing the locking member to rotate from the first state to the second state. The protruding post passes between the locking member and the fixing member from bottom to top. After the brewing container and the brewing head have completed the powder pressing and brewing, when the brewing container moves downward, the locking member and the fixing member cooperate to stop the protruding post, causing the push rod and the brewing container to move relative to each other, pushing the powder residue in the brewing container upward out of the brewing container. The limiting component has a simple and reasonable structure, both allowing the push rod to move upward and limiting its downward movement, thus realizing the pushing of residue by the push rod.

[0012] A brewing device includes a brewing head, a brewing container, and a push rod, and further includes a reset component as described in any of the above embodiments. The reset component is used to reset the push rod from its high position to its initial low position. The brewing device of this application has a simple structure, low cost, and stable push rod reset effect.

[0013] In an optional embodiment, the lower end of the push rod is provided with a pressure block, the pressure block having an upward-facing pressure surface. When the actuating member rotates downward, it presses against the pressure surface of the pressure block. This allows the lever of the actuating member to apply a downward force to the push rod through the pressure block, ensuring the push rod's reset effect.

[0014] In an optional embodiment, the housing is provided with a track, the track comprising a transverse section and a vertical section connected to and extending through the transverse section. The threaded sleeve of the transmission component is threadedly connected to the screw of the drive component. The threaded sleeve is provided with a connecting arm. The first end of the connecting arm is connected to the threaded sleeve, and the second end of the connecting arm is away from the threaded sleeve and located obliquely above the first end. The connecting arm is provided with a long groove along its length. The brewing container is provided with a limiting guide part, which is located in both the track and the long groove, so that when the screw sleeve moves up and down along the screw, the brewing container moves along the track under the action of the long groove.

[0015] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: The reset component of this application utilizes a single power source and achieves reset after the top rod pushes the slag through mechanical structure linkage. The coordinated transmission between the various mechanical structures is precise and has low noise. Moreover, it has a simple structure, reliable performance, convenient operation, and reduces energy consumption and cost.

[0032] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0033] This application provides a reset component for use in a brewing device, which can be used to brew beverages such as coffee. This application uses coffee brewing as an example for illustration.

[0034] like Figures 1 to 3 As shown, the brewing device includes a housing 4, a drive component 5, a brewing head 8, a brewing container 6, and a push rod 7. The drive component 5 and the brewing head 8 are both fixed to the housing 4. The brewing container 6 is mounted on the housing 4 and can move along the housing 4 to have an initial position away from the brewing head 8 and a brewing position engaged with the brewing head 8. One end (upper end) of the push rod 7 extends into the brewing container 6, and the other end (lower end) is located outside the brewing container 6. The push rod 7 can move with the brewing container 6 and can also rise and fall relative to the brewing container 6 under external force, having an initial low position and a high position for pushing away coffee grounds. In the initial low position, the upper end of the push rod 7 is located at the bottom of the brewing container 6. In the high position for pushing away coffee grounds, the upper end of the push rod 7 moves to the top of the brewing container 6 and pushes out the coffee grounds formed after brewing.

[0035] like Figures 1 to 14As shown, the reset assembly of this embodiment includes a limiting member 1, a toggle member 2, and a transmission member 3. The limiting member 1 is disposed on the housing 4 of the brewing device and is used to stop and limit the push rod 7 during the downward movement of the initial reset stage when the brewing container 6 is reset from the brewing position to the initial position. This causes the push rod 7 to move upward relative to the brewing container 6 from the initial low position to the slag-pushing high position, pushing the powder and slag out of the brewing container 6. The toggle member 2 is rotatably disposed on the housing 4. The transmission member 3 is connected to the driving component 5 and reciprocates vertically under the driving action of the driving component 5. When the transmission member 3 reciprocates vertically, it pushes the toggle member 2 to rotate reciprocally from the high position to the low position and from the low position to the high position. When the toggle member 2 rotates from the high position to the low position, it pushes the push rod 7, causing the push rod 7, which has been released from the limiting member 1, to move downward from the slag-pushing high position back to the initial low position.

[0036] The reset component in this embodiment uses only the original driving component 5 of the brewing device as the power source, and uses the purely mechanical transmission component 3 that reciprocates in the vertical direction to drive the actuating component 2 to rotate, and then uses the actuating component 2 to push the top rod 7 to reset. This eliminates the need for additional reset motors or electromagnets and other electrical components, which not only simplifies the structure and facilitates the miniaturization of the whole machine, but also reduces costs and makes it less prone to jamming and abnormal noise.

[0037] In some embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, the housing 4 is provided with an arc-shaped guide rail 41. The height of the first end of the arc-shaped guide rail 41 is higher than the height of the second end. The first end is the high end of the arc-shaped guide rail 41, and the second end is the low end of the arc-shaped guide rail 41. Figure 4 and Figure 5 As shown, the actuating component 2 includes a main body 21 and a lever 23. One end of the lever 23 is connected to the main body 21, and the other end passes through the arc-shaped guide rail 41. Figure 5 and Figure 6As shown, when the transmission component 3 pushes the actuating component 2 to rotate, the lever 23 can move from the first end of the arc-shaped guide rail 41 to the second end of the arc-shaped guide rail 41. This movement process is the rotation of the actuating component 2 from a high position to a low position. When the transmission component 3 pushes the actuating component 2 to rotate, the lever 23 can also move from the second end of the arc-shaped guide rail 41 to the first end of the arc-shaped guide rail 41. This movement process is the rotation of the actuating component 2 from a low position to a high position. The vertical movement of the transmission component 3 includes movement from top to bottom and movement from bottom to top, referred to as downward movement and upward movement. When the transmission component 3 moves downward, it abuts against the main body 21, applying a downward force to the main body 21, causing the main body 21 to drive the lever 23 to move from the high end of the arc-shaped guide rail 41 to the low end of the arc-shaped guide rail 41. During the movement of the lever 23, it actuates the push rod 7, applying at least a downward force to the push rod 7, causing the push rod 7 to reset from the high position of the slag pusher to the initial low position. With the help of the arc-shaped guide rail 41 on the housing 4 and the lever 23 passing through the arc-shaped guide rail 41, the actuating component 2 moves along a predetermined trajectory so as to accurately act on the push rod 7 and realize the reset of the push rod 7 from the slag pushing high position to the initial low position.

[0038] In some embodiments, such as Figure 4 As shown, the main body 21 is generally arm-shaped, with one end rotatably connected to the housing 4, for example, via a hinge shaft. The main body 21 has a first surface facing the housing 4, a second surface facing away from the housing 4, and a generally upward-facing upper end surface 24. One end of the lever 23 is connected to the first surface of the other end of the main body 21. The transmission member 3 includes a pushing part 331. When the transmission member 3 moves downward, the pushing part 331 abuts against the upper end surface 24 of the main body 21 and pushes the main body 21 to rotate downward. When the main body 21 rotates, it drives the lever 23 to move along the arc-shaped guide rail 41. The arrangement and cooperation of the main body 21, lever 23, and pushing part 331 are reasonable, facilitating the sequential transmission of power, and ultimately enabling the lever 23 to rotate along the arc-shaped guide rail 41 and actuate the top rod 7 to reset.

[0039] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the lower end face of the pushing part 331 of the transmission component 3 partially protrudes downward to form a hook 332. When the pushing part 331 pushes the main body 21 to rotate from a high position to a low position until the lever 23 is at the low end of the arc-shaped guide rail 41, the hook 332 moves to the bottom of the main body 21. When the transmission component 3 moves upward to reset, the hook 332 drives the main body 21 to move upward, causing the lever 23 to rotate from a low position to a high position, and the lever 23 resets to the high end of the arc-shaped guide rail 41. By setting the hook 332 on the pushing part 331, the reset of the actuating component 2 is achieved, preparing for the next reset of the push rod 7.

[0040] Furthermore, a stop portion 22 is protruding from the second surface of the main body 21. By utilizing the stop portion 22 in conjunction with the pushing portion 331 and the latch 332, the main body 21 can drive the lever 23 to move along the arc-shaped guide rail 41. When the stop portion 22 is provided on the second surface of the main body 21, and the transmission member 3 moves downwards, the pushing portion 331 abuts against the upper end face 24 of the stop portion 22. (See [reference]). Figure 2 .

[0041] In some embodiments, such as Figure 5 As shown, the convex arc surface near the high end of the arc-shaped guide rail 41 partially contracts inward to form a constriction portion 411. A branch groove 42 is provided on the outer side of the convex arc surface of the arc-shaped guide rail 41 between the constriction portion 411 and the high end. One end of the branch groove 42 connects to the convex arc surface near and below the constriction portion 411. The width of the constriction portion 411 is smaller than the outer diameter of the lever 23. Under external force, the lever 23 can deform the constriction portion 411 to pass through it and be confined at the high end of the arc-shaped guide rail 41. (See also...) Figure 6 By forming a limiting part 411 near the height of the arc-shaped guide rail 41 and providing a branch groove 42, deformation can occur at the limiting part 411. The lever 23 can pass through the limiting part 411 and be limited by the limiting part 411, thereby keeping the lever 23 at the high end of the arc-shaped guide rail 41 and preventing it from moving to the low end under the action of gravity.

[0042] Furthermore, the branch groove 42 is arc-shaped, and its bending direction is consistent with the bending direction of the arc-shaped groove. Moreover, the branch groove 42 penetrates the shell 4 at its location to enhance the deformation capability of the compression part 411.

[0043] In some embodiments, the driving component 5 includes a motor. The transmission component 3 includes a screw 31, a screw sleeve 32, and a pressure block 33. The screw 31 is vertically arranged and connected to the motor, which drives the screw 31 to rotate both counterclockwise and clockwise. The screw sleeve 32 is threaded onto the screw 31 and reciprocates up and down along the screw 31 when the screw 31 rotates. The lower end of the pressure block 33 forms a pushing portion 331. (See also...) Figure 1 and Figure 2 The transmission component 3 has a simple and reasonable structure, ensuring smooth and effective power transmission and preventing jamming.

[0044] In some embodiments, such as Figure 3 , Figure 4 and Figure 7As shown, the limiting member 1 includes a fixing member 11, a locking member 12, and a resetting member 13. The fixing member 11 is fixed to the housing 4, and the locking member 12 is rotatably mounted on the housing 4. The locking member 12 has a first state of abutting against the fixing member 11 and a second state of being separated from the locking member 12. The resetting member 13 is disposed between the locking member 12 and the housing 4, and is used to apply a force to the locking member 12 to keep it in the first state. The resetting member 13 can be, for example, a torsion spring.

[0045] The bottom of the push rod 7 is provided with a protruding post 71, the axial direction of which is perpendicular to the axial direction of the push rod 7. When the brewing container 6 moves from its initial position to the brewing position after collecting the powder, it initially moves laterally, causing the push rod 7 and its protruding post 71 to follow. When the brewing container 6 moves directly below the brewing head 8, the protruding post 71 is positioned directly below the fixing member 11 and the locking member 12. At this point, the brewing container 6 moves vertically towards the brewing head 8. During this approach, the protruding post 71 pushes the locking member 12 to rotate from the first state to the second state, creating a gap between the locking member 12 and the fixing member 11. The protruding post 71 then moves from bottom to top through this gap to above the locking member 12 and the fixing member 11. The locking member 12 is then reset from the second state to the first state by the action of the reset member 13. After the brewing container 6 and brewing head 8 are combined to tamp the coffee powder and brew, when the brewing container 6 moves downward, the locking member 12 and the fixing member 11 cooperate to stop the protrusion 71, causing the push rod 7 to move relative to the brewing container 6, pushing the coffee powder and residue out of the brewing container 6 upward. The limiting member 1 has a simple and reasonable structure. It does not restrict the movement of the brewing container 6 from the initial state to the brewing state for coffee brewing, and it limits the protrusion 71 and thus the push rod 7, realizing the pushing of the coffee powder and residue by the push rod 7.

[0046] Understandably, when the push rod 7 finishes pushing the slag, and the brewing container 6 continues to move laterally, it drives the push rod 7 to move laterally synchronously. The push rod 7 disengages from the limiting member 1, that is, the limiting member 1 releases the limiting of the push rod 7, so that the push rod 7 can be reset from the high position of pushing slag to the initial low position under the downward pushing action of the lever 23.

[0047] The reset component of this application has a simple structure, reliable performance, and convenient operation. It effectively solves the problems of jamming and lag caused by the complex transmission of traditional structures, and significantly improves the stability of the product and the user experience.

[0048] This application also provides a brewing device, which includes a housing 4, a driving component 5, a brewing head 8, a brewing container 6, a push rod 7, and a reset component as described in any of the above embodiments. The reset component is used to reset the push rod 7 from its high position to its initial low position, so that the brewing container 6 can be used for the next coffee brewing. The brewing device of this application, due to its simple structure, low cost, and stable reset component, also possesses the aforementioned advantages.

[0049] In some embodiments, such as Figures 11 to 14 As shown, the lower end of the push rod 7 is provided with a pressure block 72. The pressure block 72 protrudes outward in the radial direction of the push rod 7 and has an upward pressure-bearing surface. When the actuating component 2 rotates downward, it presses against the pressure-bearing surface of the pressure block 72. By setting the pressure block 72, the lever 23 of the actuating component 2 can apply a downward force to the push rod 7 through the pressure block 72, ensuring the reset effect of the push rod 7.

[0050] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the threaded sleeve 32 is provided with a connecting arm 34. The first end of the connecting arm 34 is connected to the threaded sleeve 32, and the second end of the connecting arm 34 is away from the threaded sleeve 32 and located diagonally above the first end, that is, the connecting arm 34 is set at an angle. The upper end of the pressure block 33 is connected to the lower side of the connecting arm 34, that is, the pressure block 33 is connected to the threaded sleeve 32 through the connecting arm 34. When the threaded sleeve 32 moves up and down along the screw 31, it simultaneously drives the connecting arm 34 and the pressure block 33 to move up and down.

[0051] Continue to combine Figure 1 , Figure 2 and Figure 4 The connecting arm 34 has a long groove 341 along its length. The housing 4 has a track 43, which includes a transverse section 431 and a vertical section 432 that connects to and passes through the transverse section 431. The brewing container 6 has a limiting guide part 61, which protrudes from the periphery of the brewing container 6 and is located within both the track 43 and the long groove 341, and is limited by the track 43 and the long groove 341. When the screw sleeve 32 moves up and down along the screw 31, the brewing container 6 moves along the track 43 under the action of the long groove 341.

[0052] This application, by providing a connecting arm 34 with a long slot 341, enables the drive component 5 to both drive the pressure block 33 to reset the push rod 7 and drive the brewing container 6 to switch between the initial position and the brewing position. This achieves the effects of saving power, simplifying the structure, and reducing costs.

[0053] The working process and principle of the embodiments of this application are explained below: When the brewing device is in standby mode, see Figure 1 The screw sleeve 32 is located at the lower part of the screw 31. The screw sleeve 32 drives the connecting arm 34 and the pressure block 33 to be in a low position. The pushing part 331 of the pressure block 33 pushes the lever 23 of the actuating component 2 to the lower end of the arc-shaped guide rail 41, and the lever 23 presses against the bearing block 72 of the top rod 7, so that the top rod 7 is in a low position and the brewing container 6 is in the initial position. The hook 332 below the pushing part 331 of the pressure block 33 of the transmission component 3 hooks onto the lower side of the stop part 22.

[0054] When coffee brewing is required, the brewing container 6 first collects the coffee grounds. After collection, the motor is started, and the motor drives the screw 31 to rotate in the first direction (the motor can, for example, drive the screw 31 to rotate by meshing a gear on its motor shaft with a gear on the screw 31). The screw sleeve 32 drives the connecting arm 34 and the pressure block 33 to move upward together. When the connecting arm 34 moves upward, it first drives the brewing container 6 to move horizontally along the transverse section 431 of the track 43. When the brewing container 6 moves to the connection point between the transverse section 431 and the vertical section 432, the brewing container 6 is located directly below the brewing head 8, and the protrusion 71 on the push rod 7 is located directly below the limiting member 1. See [link to relevant documentation]. Figure 5 During the continued upward movement of the screw sleeve 32 and connecting arm 34, the brewing container 6 then switches to vertical upward movement along the vertical section 432; the push rod 7 moves upward along with the brewing container 6, and the protrusion 71 on the push rod 7 pushes open the locking member 12, see [link to relevant documentation]. Figure 6 and Figure 7 And it passes between the locking member 12 and the fixing member 11, moving above both of them, see Figure 8 At the same time, the latch 332 on the pushing part 331 of the pressure block 33 moves upward with the pressure block 33, and drives the main body 21 of the actuating component 2 and the lever 23 to move upward. The lever 23 moves from the lower end to the upper end of the arc-shaped guide rail 41 to reset and remains at the upper end. See Figure 9 When the connecting arm 34 moves the brewing container 6 to the uppermost end of the vertical section 432, the motor shuts off, and the brewing container 6 engages with the brewing head 8, completing the tamping and coffee extraction brewing process. After the brewing process is completed, the motor is restarted, and the motor drives the screw 31 to rotate in a second direction opposite to the first direction. The screw sleeve 32 drives the connecting arm 34 and the pressing block 33 to move downwards together, and the brewing container 6 moves along the track 43 to enter the reset process. The reset process is specifically divided into the "top rod 7 churn-pushing stage" and the "top rod 7 reset stage". Push rod 7 during the slag-pushing stage: The brewing container 6 first moves downward along the vertical section of track 43. At this time, the push rod 7, assembled on the brewing container 6, moves downward synchronously. When the protrusion 71 at the lower end of the push rod 7 contacts the upper end face 24 of the locking member 12, the push rod 7 is subjected to a dual force: firstly, the inertial force of the brewing container 6 moving downward, forming a downward movement tendency; secondly, the upward rigid resistance force formed by the pushing of the locking member 12. Since the brewing container 6 continues to move downward under the drive of the connecting arm 34, the push rod 7 and the brewing container 6 generate relative displacement, and the push rod 7 is forced to move upward relative to the brewing container 6. See [link to relevant documentation]. Figure 11 Then, the powder residue after brewing is pushed out from the slag discharge port at the top of the brewing container 6. Under its own gravity, the powder residue falls into the slag chute arranged at the bottom and slides down the chute to the slag receiving tray, thus completing the residue cleaning.

[0055] Reset phase of push rod 7: After the slag is pushed out, the brewing container 6 moves to the lowest point of the vertical section 432. As the screw sleeve 32 continues to drive the connecting arm 34 and the pressure block 33 downward, the brewing container 6 switches from the vertical section to the horizontal section 431 under the action of the connecting arm 34, and moves horizontally along the horizontal section 431 back to the initial position. During this process, push rod 7 moves horizontally along with the brewing container 6 and disengages from the locking member 12 and the fixing member 11. As the pressure block 33 continues to move downward, the pushing part 331 at the lower end of the pressure block 33 contacts the upper end surface 24 of the main body 21 or the stop part 22 of the actuating member 2. See [reference needed]. Figure 12 The downward force of the pressure block 33 is converted into lateral pressure on the actuating member 2, driving the actuating member 2 to rotate about its hinge axis with the housing 4; as the actuating member 2 rotates, the lever 23 of the actuating member 2 simultaneously presses down on the bearing block 72 of the top rod 7, forcing the top rod 7 to move downward, see... Figure 13 When the brewing container 6 moves to the free end of the transverse section 431 and is in its initial position, the lever 23 presses the push rod 7 down to its initial low position, where its upper end is at the bottom of the brewing container 6, thus completing the reset of the push rod 7. See [link to relevant documentation]. Figure 14 In other words, the brewing device eventually returns to its initial powder receiving position under the coordinated action of the screw sleeve 32, connecting arm 34 and track 43. The push rod 7 is stably reset under the synergistic action of the pressure block 33 and lever 23. The entire mechanical reset assembly is restored to the ready-to-work state, preparing for the next coffee brewing process of powder receiving, pressure tamping, brewing and residue handling.

[0056] It is understood that the movement of the brewing container 6 is the same as in the prior art, and the process and principle of the brewing container 6 and the brewing head 8 for pressing powder and brewing are the same as in the corresponding technology. This application will not elaborate on this.

[0057] Furthermore, in order to clearly illustrate the structure of the improved portion of this application, some components have been omitted from the accompanying drawings, which are merely examples.

[0058] The brewing device of this application adopts a single power source and multi-action coordinated transmission, that is, the motor is used as the only power source, and the entire process of "pressing powder-brewing-pushing residue-resetting" is realized through mechanical structure linkage. No additional drive components (such as motors, electromagnets, etc.) are required. By using motion trajectory switching (horizontal → vertical → horizontal) and force transmission conversion, multi-process automation is realized, simplifying the design of the power system.

[0059] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
