Description

Technical Field

[0001] This utility model relates to the field of beverage preparation technology, and in particular to a beverage machine. Background Technology

[0002] Machines for preparing beverages, particularly coffee or tea, are known in the art, and these machines include a brewing unit comprising a brewing chamber with an opening through which the material to be brewed can be introduced and discharged.

[0003] Taking the brewing unit of a fully automatic coffee machine as an example, it typically includes an automated brewing unit (or brewer) to complete the entire process from grinding, tamping, brewing to discharging the grounds. In this automated process, components such as the brewing cylinder and piston within the brewing unit need to rotate and move axially precisely. Therefore, real-time and accurate position detection of these moving parts is a key technological prerequisite for ensuring a smooth and reliable brewing process.

[0004] A common approach is to use multiple independent microswitches to detect different rotational positions of the brewing cylinder and different axial positions of the lower piston. In this approach, each sensor corresponds to a moving part, requiring separate sensors and their mounting structures for different detection positions. This not only increases the number of parts and cost but also makes the internal mechanical structure and wiring of the brewing unit more complex, causing inconvenience for assembly and maintenance.

[0059] The repeated use of reference numerals in this specification and the accompanying drawings is intended to indicate the same or similar features or elements of this application. Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be noted that in the description of this utility model, the terms "upper" and "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0061] This embodiment provides a beverage machine 100, which is particularly capable of automatically brewing beverages such as coffee and tea. To make the objectives, technical solutions, and advantages of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0062] Specifically, refer to Figures 1 to 3 In one embodiment of this utility model, a beverage machine 100 is provided, including a brewing head 22, a brewing cylinder 31, and a lower piston 32. The lower piston 32 is at least partially placed inside the brewing cylinder 31 and is axially movable relative to the brewing cylinder 31. The brewing head 22 and the lower piston 32 are respectively engaged with both ends of the brewing cylinder 31 to form a brewing chamber. During the brewing process, the beverage ingredients are placed in the brewing chamber, and the brewing head 22 moves downward to compress the space inside the brewing chamber, pressing the beverage ingredients into a cake shape. Then, water at a suitable temperature is introduced into the brewing chamber to fully contact and extract the beverage that meets the user's needs. The brewing head 22 and the brewing cylinder 31 are both disposed within the body 20 of the beverage machine 100. The body 20 can be a shell or frame used to support or install various functional components. The body 20 can be a single unit or assembled from frames supporting various functional components.

[0063] Furthermore, the beverage machine 100 also includes a first motor 41 and a transmission mechanism 35, which are connected to the lower piston 32 for driving the lower piston 32 to move axially along the brewing cylinder 31 and to rotate the brewing cylinder 31. The transmission mechanism 35 can be any structure capable of driving the brewing cylinder 31 to move and rotate, such as a lead screw and nut structure, a gear and rack structure, etc. The term "transmission connection" here is a general term well-known to those skilled in the art, and can refer to the transmission of power and motion through one or more mechanical structures such as gears, connecting rods, and cams.

[0064] In this embodiment, the brewing head 22, brewing cylinder 31, lower piston 32, and related components constitute the brewing unit. The transmission mechanism 35 includes a first transmission member 351 that is driveably connected to the brewing cylinder 31. The beverage machine 100 is provided with a turntable 40 that is driveably connected to the first transmission member 351. The first motor 41 drives the turntable 40 to rotate synchronously with the first transmission member 351. It can be understood that "synchronous rotation" means that the rotation angle of the turntable 40 and the rotation angle of the first transmission member 351 maintain a strict correspondence.

[0065] Specifically, the first transmission component 351 is constructed as an input gear. The transmission mechanism 35 also includes a gear and rack assembly that is connected to the input gear. The lower piston 32 is connected to the rack. The movement of the rack pushes the lower piston 32 to move axially along the brewing cylinder 31, thereby automating the slag pushing and powder receiving processes of the brewing cylinder 31. When the transmission force from the input gear to the gear and rack assembly is less than the frictional force between the piston 32 and the brewing cylinder 31, the input gear drives the brewing cylinder 31 to rotate around the axis of the input gear. When the transmission force from the input gear to the gear and rack assembly is greater than the frictional force between the lower piston 32 and the brewing cylinder 31, the input gear drives the lower piston 32 to move axially along the brewing cylinder 31 through the gear and rack assembly.

[0066] A first detection element 51 and a second detection element 52 are spaced apart around the circumference of the turntable 40. The turntable 40 is configured to trigger or de-trigger with the first detection element 51 and the second detection element 52 respectively during rotation to indicate the position of the brewing tank 31. The first detection element 51 and the second detection element 52 can be microswitches, Hall sensors, or photoelectric sensors, etc. Here, "trigger" means that the detection element generates a valid signal due to its interaction with a specific part of the turntable 40, and "de-trigger" means that it does not generate a valid signal or returns to its initial state.

[0067] By placing two detection elements on the periphery of the turntable 10, a unified detection module (turntable 40 and two detection elements) replaces the original scattered, one-to-one detection scheme, which significantly simplifies the mechanical structure of the brewing unit, reduces the number of parts, thereby reducing manufacturing costs and assembly difficulty, and improving the system's integration and operational reliability.

[0068] When the turntable 40 rotates to a specific angle, the triggering or de-triggering states of the first detection element 51 and the second detection element 52 correspond to the position of the brewing cylinder 31, thereby monitoring the specific angle and position of the brewing cylinder 31 during rotation in real time. This setting allows for accurate control of the positional changes of the brewing cylinder 31 under different operating conditions, ensuring that beverage ingredients are uniformly compressed and extracted within the brewing chamber, improving the taste and quality of the beverage. Simultaneously, this detection structure can also provide feedback on abnormal displacement or jamming during the brewing process, allowing for timely adjustment or shutdown of the equipment to prevent equipment damage or impact on the stability of beverage preparation. Furthermore, the linkage design between the first motor 41 and the turntable 40 and the transmission components achieves precise positioning and efficient transmission of the brewing cylinder 31, improving the overall automation level and ease of operation of the equipment.

[0069] Furthermore, the triggering or de-triggering states of the first detection element 51 and the second detection element 52 also correspond to the position of the lower piston 32. For example, when the brewing cylinder 31 is held in one position, the lower piston 32 can move along the axial direction of the brewing cylinder 31 to the upper position (top slag state) and the lower position (pressed powder or brewing state) of the brewing cylinder 31. As the position of the lower piston 32 changes, the triggering or de-triggering states of the first detection element 51 and the second detection element 52 can also change to indicate the position of the lower piston 32.

[0070] To achieve the aforementioned triggering and disconnecting triggering functions, in one specific embodiment, a first triggering part 411 and a second triggering part 412 are provided on the circumferential surface of the turntable 40. The first triggering part 411 is used to trigger the first detection element 51, and the second triggering part 412 is used to trigger the second detection element 52. The first triggering part 411 and the second triggering part 412 overlap along the circumferential direction of the turntable 40.

[0071] This overlapping design allows the turntable 40 to simultaneously activate two detection elements when rotating to a specific angle range, generating a clear signal combination that indicates both elements are triggered. This signal combination can be used by the controller to accurately identify a critical working position, such as the brewing preparation position, thereby improving control reliability. When the turntable 40 rotates, the first trigger 411 and the second trigger 412 simultaneously trigger the first detection element 51 and the second detection element 52 in the overlapping area, forming continuous signal feedback and further improving detection accuracy and stability. This structural design enables precise identification of the angular position of the brewing cylinder 31, ensuring accurate control of the brewing cylinder 31's state by the beverage machine 100 at different operating stages. In practical applications, the overlapping arrangement of the first trigger 411 and the second trigger 412 allows the turntable 40 to continuously detect the same position of the brewing cylinder 31 during rotation, avoiding detection blind spots and effectively improving the reliability and stability of equipment operation.

[0072] Furthermore, the first trigger part 411 and the second trigger part 412 are configured in at least one of the following ways: the first trigger part 411 and the second trigger part 412 are arranged along the axial direction of the turntable 40, and correspondingly, the two detection elements are also offset along the axial direction; or the circumferential extension length of the second trigger part 412 along the turntable 40 is greater than the circumferential extension length of the first trigger part 411 along the turntable 40, to correspond to different state durations; or the first trigger part 411 protrudes from the circumferential surface of the turntable 40, and the second trigger part 412 is configured on the circumferential surface of the turntable 40. The axially arranged first trigger part 411 and the second trigger part 412 enable the first detection element 51 and the second detection element 52 to be triggered independently during the rotation of the turntable 40, thereby realizing the detection and judgment of different positions / different states of the brewing tank 31.

[0073] During the brewing process, when the turntable 40 drives the first triggering part 411 and the second triggering part 412 to trigger or disconnect the first detection element 51 or the second detection element 52 respectively, the controller can determine the specific stage of the brewing cylinder 31 based on the changes in the trigger signal, and adjust the motor speed, direction, or stop accordingly to ensure the accuracy and consistency of beverage brewing. Furthermore, the axially arranged triggering parts can fully utilize the circumferential space of the turntable 40, so the rotation of the turntable 40 can trigger changes in the triggering state of different triggering parts.

[0074] Furthermore, the second trigger unit 412 has a longer trigger range during the rotation of the turntable 40, thereby extending the recognition time of the corresponding detection element for the position status of the brewing cylinder 31 and improving the system's fault tolerance and stability. Utilizing the circumference of the turntable 40 as the second trigger unit 412 simplifies the structural design while ensuring functional coordination between the second trigger unit 412 and the first trigger unit 411. This design not only reduces manufacturing costs but also improves the maintainability and assembly efficiency of the equipment.

[0075] Accordingly, to achieve disconnection triggering, the circumferential surface of the turntable 40 is provided with a first clearance portion 421 and a second clearance portion 422. The first clearance portion 421 cooperates with the first detection element 51 to disconnect the triggering of the first detection element 51, and the second clearance portion 422 cooperates with the second detection element 52 to disconnect the triggering of the second detection element 52. The first clearance portion 421 and the second clearance portion 422 are spaced apart along the circumference of the turntable 40. By setting the clearance portions, signal combinations of "both are disconnected" or "one is triggered while the other is disconnected" can be generated, thus forming a complete signal generation mechanism and providing a basis for complex program control.

[0076] Similarly, the first clearance portion 421 and the second clearance portion 422 are configured in at least one of the following ways: the first clearance portion 421 and the second clearance portion 422 are arranged along the axial direction of the turntable 40; or the length of the first clearance portion 421 extending circumferentially along the turntable 40 is greater than the length of the second clearance portion 422 extending circumferentially along the turntable 40; or the first clearance portion 421 is configured on the circumferential surface of the turntable 40, and the second clearance portion 422 is recessed on the circumferential surface of the turntable 40.

[0077] When the first clearance portion 421 and the second clearance portion 422 are arranged axially, they can form a staggered disconnection signal feedback during the rotation of the turntable 40, thereby enhancing the accuracy of the system's judgment of the brewing cylinder 31's position. When the circumferential extension length of the first clearance portion 421 is greater than that of the second clearance portion 422, the corresponding disconnection time is longer, facilitating the controller's identification and response to specific states. If the first clearance portion 421 is directly formed by the circumferential surface of the turntable 40, while the second clearance portion 422 is a recessed structure, the manufacturing process can be further simplified while ensuring signal distinguishability. The combination of the above structural schemes satisfies functional requirements while also taking into account production efficiency and equipment stability.

[0078] The arc lengths of the first trigger part 411 and the second trigger part 412 are related to the rotational stroke of the brewing cylinder 31 and the axial movement stroke of the lower piston 33 along the brewing cylinder 31. In this embodiment, the central angle corresponding to the first trigger part 411 is between 230 and 250 degrees, and correspondingly, the central angle corresponding to the first clearance part 421 is between 130 and 110 degrees; the central angle corresponding to the second trigger part 412 is between 330 and 360 degrees, and correspondingly, the central angle corresponding to the second clearance part 422 is between 0 and 30 degrees.

[0079] In this embodiment, the first trigger part 411 and the first clearance part 421 together form a circumference along the circumference of the turntable 40; the second trigger part 421 and the second clearance part 422 together form another circumference along the circumference of the turntable 40, and the two circumferences are arranged along the axial direction of the turntable 40.

[0080] To clearly describe the workflow of the beverage machine 100, key positions are first defined. The brewing cylinder 31 can rotate between a first position and a second position. In the first position, the brewing cylinder 31 is coaxial with the brewing head 22. This position is used for pressing the powder and brewing. The brewing head 22 can engage with the brewing cylinder 31 and compress the space of the brewing chamber to press the powder into a cake for subsequent brewing operations. In the second position, the brewing cylinder 31 is misaligned with the brewing head 22. This position is typically the initial position or the powder receiving position. Simultaneously, in either the first or second position, the lower piston 32 can move along the axial direction of the brewing cylinder 31 between an upper position and a lower position. The lower position is the initial or brewing position, and the upper position is the position for ejecting the powder cake residue.

[0081] Based on the above definitions, the motion logic relationship between the turntable 40, the brewing cylinder 31, and the lower piston 32 is as follows:

[0082] Reference Figure 4-7 and Figure 9-10 As turntable 40 rotates along the first direction (e.g., along...) Figure 10(The arrow points in the forward direction). Within the triggering range of the first triggering part 411, the brewing cylinder 31 is in the first position, and the lower piston 32 is in the lower position and can move to the upper position. Within the triggering range of the second triggering part 412, the brewing cylinder 31 is in the first position, and the lower piston 32 is in the lower position and can move to the upper position.

[0083] Reference Figure 7 and Figure 11-12 As the turntable 40 rotates in the opposite direction (e.g., reverses), within the triggering range of the second triggering part 412, the brewing cylinder 31 rotates from the first position to the second position, and the lower piston 32 is in the upper position and can move to the lower position.

[0084] When the turntable 40 rotates along the first direction to the triggering range of the first triggering part 411, the brewing cylinder 31 remains in the first position, and the brewing head 22 moves downward to engage with the brewing cylinder 31, gradually compressing the internal space of the brewing cylinder 31 to compact the powder and form a uniform powder cake. Then, brewing water is injected, and the brewed beverage is output. After brewing, the brewing head 22 moves upward to separate from the brewing cylinder 31, and the lower piston 32 moves to the upper position to push out the powder cake residue. When the turntable 40 rotates in the opposite direction along the first direction to the triggering range of the second triggering part 412, the brewing cylinder 31 rotates from the first position to the second position, and the powder cake residue pushed out by the lower piston 32 leaves the lower piston 32 as the brewing cylinder 31 rotates, falling into the residue collection container 23; the lower piston 32 returns to the lower position for the next powder collection.

[0085] Furthermore, within the disconnection trigger range of the first clearance section 421, the brewing cylinder 31 rotates from the second position to the first position, and the lower piston 32 is in the lower position; within the disconnection trigger range of the second clearance section 422, the brewing cylinder 31 is in the second position, and the lower piston 32 is in the lower position. Through the above precise correspondence, it is ensured that the beverage machine 100 can complete the entire working cycle according to the preset sequence and logic.

[0086] In the above embodiment, by utilizing the positional change of a single turntable 40 and cooperating with two detection elements, and by combining the different trigger signals generated by the two detection elements at different rotation angles of the turntable 40, the rotational position of the brewing cylinder 31 and the axial position of the lower piston 32 can be determined simultaneously. This integrated design can simultaneously reflect the states of both the brewing cylinder 31 and the lower piston 32, thereby simplifying the overall mechanical structure and reducing the number of parts and assembly costs.

[0087] In one of the alternative structural schemes, such as Figure 3As shown, the beverage machine 100 also includes a reduction mechanism 45, which transmits the power of the first motor 41 to the transmission mechanism 35, thereby providing greater torque and smoother control for the rotation of the brewing cylinder 31 and the movement of the lower piston 32. Specifically, the reduction mechanism 45 includes an output gear 451 and a gear set 452. The output gear 451 is coaxial with the rotation axis of the brewing cylinder 31, and the gear set 452 is driven between the first motor 41 and the output gear 451, reducing the rotation of the first motor 41 before transmitting it to the output gear 451. The output gear 451 has two axial output ends. A turntable 40 is located at the end of the output gear 451 away from the brewing cylinder 31, and the rotation of the output gear 451 drives the turntable 40 to rotate synchronously. A first transmission member 351 is driven to the other end of the output gear 451, and when the output gear 451 rotates, it drives the first transmission member 351 to rotate synchronously.

[0088] Meanwhile, in the vertical spatial layout, the first detection element 51 is located on the side of the turntable 40 away from the gear set 452, and the second detection element 52 is located on the side of the turntable 40 adjacent to the gear set 452. This arrangement allows the first detection element 51 and the second detection element 52 to be distributed on different sides of the turntable 40, thereby enabling more accurate identification of the positional changes of the turntable 40 at different working stages and improving the reliability of the detection. Furthermore, this layout facilitates assembly and maintenance, making the installation and adjustment of the detection elements more convenient.

[0089] Furthermore, the reduction mechanism 45 can be housed inside the gearbox, while the turntable 40 is located outside the gearbox. The first detection element 51 and the second detection element 52 can be mounted on the gearbox. The gearbox design not only protects the internal output gear 451 and gear set 452 from external environmental interference but also provides stable support for the entire transmission system. The turntable 40's location outside the gearbox makes its installation and engagement with the detection elements more intuitive and convenient, facilitating maintenance or replacement and improving the maintainability of the beverage machine 100.

[0090] Optionally, the first triggering part 411 and the second triggering part 412 are arranged sequentially from the brewing cylinder 31 to the output gear 451. Furthermore, the first detection element 51 and the second detection element 52 are arranged vertically opposite each other, and different parts of the circumference of the turntable 40 are used to trigger the first detection element 51 and the second detection element 52 respectively. This overall layout design is compact and provides reliable transmission.

[0091] Based on the above structure, the beverage machine 100 of this utility model establishes a clear logic for the correspondence between signals and states. Specifically, the turntable 40 is configured in at least one of the following ways: (Refer to...) Figure 7-8 as well as Figure 12In the upper position, the turntable 40 simultaneously engages with the first detection element 51 and the second detection element 52 to indicate the second position; see reference. Figure 4-6 as well as Figure 9-12 In the lower position, the turntable 40 is simultaneously triggered with both the first detection element 51 and the second detection element 52 to indicate a first position; the turntable 40 is simultaneously detrimentalized from both the first detection element 51 and the second detection element 52 to indicate a second position and a lower position; the turntable 40 is detrimentalized from the first detection element 51 but remains triggered with the second detection element 52 to indicate a first position and an upper position. This design allows the controller to unambiguously identify at least three key system states with just two simple switching signals, greatly improving the robustness of the control.

[0092] To achieve fully automatic control, the beverage machine in this embodiment also includes a controller (not shown in the figure) and a second motor 25. The controller receives trigger signals from the first detection element 51 and the second detection element 52. The first motor 41 and the second motor 25 are communicatively connected to the controller. The second motor 25 drives the brewing head 22 to move relative to the brewing cylinder 31 to perform the actions of pressing powder and resetting. The trigger signals of the first detection element 51 and the second detection element 52, or the disconnection of the trigger signals, indicate the state of the beverage machine 100. The controller executes a preset control program based on the received signal combination. The specific control flow is as follows:

[0093] Reference Figure 4 and Figure 9 In the initial state, the trigger signals of the first detection element 51 and the second detection element 52 are disconnected, and the controller is configured to allow the first motor 41 to start in the first direction and restrict the second motor 25 from starting. After the controller receives the grinding end signal, it checks whether the first microswitch and the second microswitch have no signal. At this time, the controller confirms that the brewer is in the initial state.

[0094] Reference Figure 5-6 and Figure 10 In the beverage preparation state, for example, when the turntable 40 rotates 30 degrees from its initial state, both the first detection element 51 and the second detection element 52 are triggered. The controller is configured to restrict the start of the first motor 41 and allow the start of the second motor 25. For example, when the first motor 41 rotates forward (i.e., starts in the first direction), it drives the turntable 40 to rotate, causing both the first detection element 51 and the second detection element 52 to be triggered. The controller determines that the brewing cylinder 31 is aligned with the brewing head 22. At this time, the controller starts the second motor 25 to perform the downward pressing of the brewing head 22 along the axial direction of the brewing cylinder 31, water inlet brewing, and the reset action of the brewing head 22.

[0095] The downward pressing of the brewing head 22 along the axial direction of the brewing cylinder 31 and the reset of the brewing head 22 can be indicated by the stall state of the second motor 25 rotating in two directions, for example by detecting the current of the second motor 25 to confirm the stall state of the second motor 25.

[0096] Reference Figure 7 and Figure 11 In the top-slag state, for example, when the turntable 40 rotates from 30 degrees to 280 degrees from the initial state, the trigger signal of the first detection element 51 is disconnected, and the second detection element 52 is triggered. The controller is configured to restrict the start of the second motor 25 and allow the first motor 41 to start in the first direction. After brewing, the first motor 41 continues to rotate forward. When the brewing tank 31 enters the top-slag state, the trigger signal of the first detection element 51 is disconnected, and the second detection element 52 is triggered to indicate that the lower piston 32 has reached the upper position. The controller is configured to restrict the start of the second motor 25 and allow the first motor 41 to start in the first direction until the controller determines that the lower piston 32 has reached the upper position.

[0097] Reference Figure 8 and Figure 12 In the slag-scraping state, for example, when the turntable 40 returns from 280 degrees to 250 degrees from its initial position, both the first detection element 51 and the second detection element 52 are triggered. The controller is configured to allow the first motor 41 to start in the reverse direction and restrict the second motor 25 from starting. During the reverse rotation of the first motor 41, it will pass through the slag-scraping state, that is, both the first detection element 51 and the second detection element 52 are triggered. The controller is configured to allow the first motor 41 to start in the reverse direction and restrict the second motor 25 from starting, until the lower piston 32 returns to the lower position, and the signals of both detection elements are disconnected, completing one working cycle.

[0098] This complete closed-loop control system enables precise automation of the brewing process.

[0099] In addition, in an optional embodiment, sensors can be set at the initial position and the powder pressing position of the brewing head 22 to detect whether it is in position, instead of directly determining whether it is in position by the stall state. This method can achieve more precise control over the position of the brewing head 22.

[0100] Reference Figure 9-12The turntable 40 has a first triggering part 411, a first clearance part 421, a second triggering part 412, and a second clearance part 422 on its circumferential surface. The first triggering part 411 and the first clearance part 421 are distributed sequentially along the circumference of the turntable 40, and the second triggering part 412 and the second clearance part 422 are also distributed sequentially along the circumference of the turntable 40. The first triggering part 411 and the second triggering part 412 are distributed sequentially along the axial direction of the turntable 40. The first detection element 51 and the second detection element 52 are misaligned along the axial direction of the turntable 40. The first detection element 51 is triggered by the first triggering part 411 and deactivated by the first clearance part 421; the second detection element 52 is triggered by the second triggering part 412 and deactivated by the second clearance part 422. With the above arrangement, the first detection element 51 and the second detection element 52 can obtain the state changes of triggering and deactivation during the rotation of the turntable 40, thereby feeding back corresponding signals to the controller. The controller identifies the current position of the brewing cylinder 31 and the lower piston 32 based on these signal changes, thereby achieving precise control over the start, stop and direction of the first motor 41 and the second motor 25.

[0101] Continue to refer to Figures 1 to 12 The beverage machine 100 includes a brewing head 22, a brewing cylinder 31, a lower piston 32, a controller (not shown), a first motor 41, and a second motor 25. The lower piston 32 is at least partially located within the brewing cylinder 31 and is axially movable relative to the brewing cylinder 31. The brewing head 22 and the lower piston 32 are respectively engaged with both ends of the brewing cylinder 31 to form a brewing chamber. The second motor 25 drives the brewing head 22 to move relative to the brewing cylinder 31. The controller is communicatively connected to both the first motor 41 and the second motor 25 and can control the operation of the first motor 41 and the second motor 25 respectively. A transmission mechanism 35 drives the first motor 41 and the lower piston 32 to move the lower piston 32 axially along the brewing cylinder 31 and to rotate the brewing cylinder 31.

[0102] The transmission mechanism 35 includes a first transmission component 351 that is connected to the brewing cylinder 31. The beverage machine 100 is provided with a turntable 40 that is connected to the first transmission component 351. A first detection element 51 and a second detection element 52 are arranged at intervals around the turntable 40. The turntable 40 is configured to form a trigger or disconnect trigger state with the first detection element 51 and the second detection element 52 respectively during rotation to generate a detection signal. The controller is used to receive the detection signal and control the operation of the first motor 41 and the second motor 25 based on the detection signal.

[0103] Through the above structural design, the beverage machine 100 can achieve highly automated and intelligent operation in actual operation. When the user issues a beverage brewing command, the controller starts the first motor 41 according to the preset program, driving the turntable 40 to rotate. Through the cooperation of the detection element and the trigger, the position information or position change information of the brewing cylinder 31 and the lower piston 32 are fed back in real time. When the detection signal changes, the controller accurately judges the current state and controls the lifting and lowering of the lower piston 32 and the rotation of the brewing cylinder 31 to complete the compaction of the powder and brewing. At the same time, the second motor 25 drives the brewing head 22 to move according to the command, forming a sealed cavity with the brewing cylinder 31 to ensure stable pressure during the brewing process. The entire system is based on closed-loop feedback control, realizing refined management of the brewing process, thereby improving the consistency of beverage taste and the stability of equipment operation.

[0104] In one specific embodiment, a first trigger part 411 and a second trigger part 412 are provided on the circumferential surface of the turntable 40, and the first trigger part 411 and the second trigger part 412 overlap along the circumferential direction of the turntable 40; during the process of the first motor 41 driving the transmission mechanism 35 to rotate the brewing cylinder 31 and drive the lower piston 32 to move along the axis of the brewing cylinder 31, the first transmission member 351 synchronously drives the first trigger part 411 and the second trigger part 412 to rotate, thereby causing the first trigger part 411 to trigger the first detection element 51 or / and the second trigger part 412 to trigger the second detection element 52.

[0105] When the first trigger unit 411 triggers the first detection element 51 or the second trigger unit 412 triggers the second detection element 52, the detection element immediately generates a feedback signal or the feedback signal changes. The controller then identifies the relative position of the brewing cylinder 31 and the lower piston 32. This structural design enables synchronous monitoring of the rotation angle of the brewing cylinder 31 and the displacement of the lower piston 32 during the operation of the beverage machine 100, ensuring precise control of the powder compaction and brewing time. This design further enhances the automation level of the beverage machine 100, making the brewing process more intelligent and efficient.

[0106] The specific movement process of the brewing cylinder 31 and the lower piston 32, and the corresponding relationship between the triggering and disconnection of the first detection element 51 and the second detection element 52 are the same as those in the above-described implementation method, and will not be repeated here.

[0107] Reference Figure 13 In another embodiment, the first detection element 51 and the second detection element 52 are arranged opposite each other in the horizontal direction, and different parts of the circumference of the turntable 40 are used to trigger the first detection element 51 and the second detection element 52 respectively.

[0108] The beverage machine 100 described above, by setting up a turntable 40 that rotates synchronously with the first transmission component 351, and having this turntable 40 cooperate with two detection elements, can simultaneously determine the rotational position of the brewing cylinder 31 and the axial position of the lower piston 32 by utilizing the different trigger signal combinations generated by the turntable 40 and the two detection elements at different rotation angles. This design replaces the original scattered, one-to-one detection scheme with a unified detection module (turntable 40 and two detection elements), significantly simplifying the mechanical structure of the brewing unit, reducing the number of parts, thereby reducing manufacturing costs and assembly difficulty, and improving the system integration and operational reliability. In addition, the beverage machine 100 can perform a fully automatic brewing process, enhancing the user experience.
