[0021] Example 1 The flavor and quality of pour-over coffee are controlled by factors such as the water pouring path and flow rate during the brewing process. Currently, coffee making still leans towards manual methods. For more information, please refer to [link to relevant documentation / reference]. Figure 1This application provides a brewing trajectory drive control device 100, including: a signal acquisition module 110, a main control module 120, a drive module 130, and an actuator 140; the main control module 120 is electrically connected to the signal acquisition module 110 and the drive module 130 respectively; the drive module 130 is also electrically connected to the actuator 140, and the actuator 140 includes: a motor gear 141, a drive gear 142, a water injection shaft gear 143, and a center water distribution shaft gear 144. The motor gear 141 meshes with the drive gear 142, the output end of the drive gear 142 is connected to the input end of the water injection shaft gear 143, and the water injection shaft gear 143 also meshes with the center water distribution shaft gear 144.

[0022] In this embodiment, please refer to Figure 2 The system includes a motor gear 141, a drive gear 142, a water injection shaft gear 143, and a center water distribution shaft gear 144. The input end of the motor gear 141 is connected to the output end of the drive module 130. The drive module 130 outputs torque to drive the motor gear 141 to rotate. The motor gear 141 sequentially transmits power to the drive gear 142, the water injection shaft gear 143, and the center water distribution shaft gear 144, causing the center water distribution shaft gear 144 to rotate in a whirlwind motion, simulating the trajectory of a hand-pumped drink.

[0023] It should be noted that the gear ratio between the water injection shaft gear 143 and the middle water distribution shaft gear 144 is 1:N. After the middle water distribution shaft gear 144 rotates N times, the water injection shaft gear 143 rotates 1 time. The gear ratio between the motor gear 141 and the drive gear 142 is 1:M. After the motor gear 141 rotates M times, the drive gear 142 rotates 1 time.

[0024] In one embodiment, the drive module 130 includes a drive motor, the output end of which is connected to the motor gear 141.

[0025] The drive motor outputs torque to drive the motor gear 141 to rotate. The motor gear 141 sequentially transmits power to the drive gear 142, the water injection shaft gear 143, and the central water distribution shaft gear 144, causing the central water distribution shaft gear 144 to rotate in a vortex motion, simulating the hand-pouring trajectory. It should be noted that the simulated hand-pouring trajectory in this application is achieved through the rotation of the motor gear 141, drive gear 142, water injection shaft gear 143, and central water distribution shaft gear 144. The trajectory is formed based on the tooth ratio and transmission relationship between the gears. By precisely controlling the gear speed and direction of rotation, the central water distribution shaft gear 144 forms a spiral or circular motion trajectory similar to that of hand-pouring. This mechanical transmission design ensures the stability and repeatability of the trajectory, and allows for flexible changes in the trajectory's range, speed, and other characteristics by adjusting gear parameters such as the tooth ratio, thereby simulating the water flow path of different hand-pouring techniques and ultimately achieving standardized control of the extraction process.

[0026] In one embodiment, the brewing trajectory drive control device 100 further includes an interaction module, which is electrically connected to the main control module 120.

[0027] In this embodiment, the interaction module is used to realize human-computer interaction, specifically including: receiving user operation instructions, such as start, stop, adjust parameters, etc., and converting these instructions into electrical signals and transmitting them to the main control module 120; at the same time, the interaction module can also provide the user with visual feedback on the operating parameters during the simulated hand-pouring process, such as working progress, current mode, etc.

[0028] In one embodiment, the main control module 120 includes a main control chip, which is electrically connected to the signal acquisition module 110 and the drive module 130 respectively.

[0029] In this embodiment, the main control chip includes, but is not limited to, a central processing unit (CPU).

[0030] In one embodiment, the actuator 140 includes a water injection pump, and the signal acquisition module 110 includes a flow meter installed at the output end of the water injection pump and electrically connected to the main control module 120.

[0031] In this embodiment, the main function of the water injection pump is to provide power and realize the delivery and injection of liquid; while the signal acquisition module 110 is responsible for collecting operating data during the water injection process, including the flow meter, a key detection component. To accurately monitor the water injection volume, the flow meter is installed at the output end of the water injection pump, that is, at the outlet where the water pump delivers liquid. This allows direct acquisition of the liquid flow rate data output after pressurization by the water injection pump. Simultaneously, the flow meter is electrically connected to the main control module 120, converting the acquired flow data into an electrical signal and transmitting it to the main control module 120 in real time. The main control module 120 can then determine whether the water injection volume meets the requirements based on this data, and adjust the control commands to the water injection pump accordingly, achieving precise control of the water injection flow rate.

[0032] In one embodiment, the actuator 140 further includes: a drive gear top cover 145 that covers one axial side of the drive gear 142, the drive gear top cover 145 having a clearance hole and a mounting groove; the signal acquisition module 110 includes: a micro switch 111, the micro switch 111 being fixed in the mounting groove of the drive gear top cover 145, and the trigger end of the micro switch 111 being radially aligned with the clearance hole.

[0033] In this embodiment, please refer to Figure 2 and Figure 3The drive gear top cover 145 protects the drive gear 142 and is provided with clearance holes, such as... Figure 3 The portion indicated by the rectangular frame 1, the clearance hole is a reserved trigger space for the micro switch 111; the drive gear top cover 145 is also provided with a mounting groove, such as... Figure 3 The portion indicated by the rectangular frame 2 is used to fix the micro switch 111.

[0034] It should be noted that the trigger end of the micro switch 111 is also radially aligned with the clearance hole on the drive gear top cover 145, that is, perpendicular to the axis of the drive gear 142. This means that when the drive gear 142 rotates, if there is a protruding structure on its edge, it will directly contact the trigger end of the micro switch 111 at the clearance hole, thereby causing the micro switch 111 to generate an electrical signal, which is then transmitted to the associated main control module 120, ultimately realizing the detection of the rotation state of the drive gear 142, such as whether the drive gear 142 has rotated to a specific position or whether it is operating normally.

[0035] In one embodiment, the signal acquisition module 110 further includes a contact 112, which protrudes from the axial end face of the drive gear 142. The contact 112 is an elastically retractable structure. When the contact 112 is located inside the clearance hole, the movable end of the contact 112 protrudes from the axial end face of the drive gear 142. When the contact 112 is located below the drive gear top cover 145, the movable end of the contact 112 is flush with the axial end face of the drive gear 142.

[0036] In this embodiment, please refer to Figure 3 and Figure 4 The contact 112 protrudes from the axial end face of the drive gear 142, specifically from the end face near the drive gear top cover 145. The contact 112 is linked to a micro switch. When the drive gear 142 rotates, causing the contact 112 to rotate into the clearance hole, the movable end of the contact 112 protrudes from the axial end face of the drive gear 142 due to the absence of a top cover at the clearance hole. At this point, the contact 112 is ready to trigger the micro switch 111. As the contact 112 continues to rotate with the drive gear 142 and enters below the drive gear top cover 145, the drive gear top cover 145 exerts a squeezing force on the movable end of the contact 112, causing the micro switch 111 to retract and eventually align its movable section with the axial end face of the drive gear 142. This cyclical change of convex-contraction can precisely coordinate with the micro switch 111 to achieve intermittent triggering, thereby transmitting the operating status signal of the drive gear 142, such as the number of rotations and position information, to the main control module 120.

[0037] In one embodiment, the actuator 140 further includes a center water-shaft gear cover 146 that covers the center water-shaft gear; the signal acquisition module 110 further includes a magnet 113, which is installed in the gap between the center water-shaft gear 144 and the center water-shaft gear cover 146.

[0038] In this embodiment, please refer to Figure 2 The center-parting shaft gear cover 146 covers the center-parting shaft gear 144, providing protection, limiting, or stabilizing the gear's operation. The signal acquisition module 110 includes a magnet 113, used to assist in acquiring the operating data of the center-parting shaft gear 144, such as rotational speed and number of rotations. To ensure stable installation and precise linkage with the center-parting shaft gear 144 to transmit magnetic signals, the magnet 113 is installed in the gap between the center-parting shaft gear 144 and the center-parting shaft gear cover 146. This position does not affect the normal rotation of the center-parting shaft gear 144 while allowing the magnet 113 to rotate synchronously with the gear. By detecting changes in the magnetic field generated by the magnet 113, the mechanical operating state of the center-parting shaft gear 144 is converted into an electrical signal, which is then transmitted to the main control module 120 to achieve real-time monitoring of the center-parting shaft gear 144's operation.

[0039] In one embodiment, the actuator 140 further includes a fixed bottom cover 147, and the signal acquisition module 110 further includes a dry spring 114, which is electrically connected to the main control module 120. The dry spring 114 is mounted on the fixed bottom cover 147. When the magnet 113 rotates to a position below the dry spring 114, the dry spring 114 is turned on, and when the magnet 113 does not rotate to a position below the dry spring 114, the dry spring 114 is turned off.

[0040] In this embodiment, please refer to Figure 2 The dry spring 114 is mounted on the fixed base cover 147, forming a fixed detection point. When the magnet 113, installed at the center split shaft gear 144, rotates with the gear and reaches directly below the dry spring 114, the magnetic field generated by the magnet 113 causes the metal spring sheet inside the dry spring 114 to attract. When the magnet 113 rotates away and is no longer below the dry spring 114, the magnetic field disappears, and the metal spring sheet of the dry spring 114 breaks under its own elastic force. This cyclical change of conduction and disconnection generates a pulse electrical signal, which is transmitted to the main control module 120 in real time. By identifying the frequency or number of times the signal is received, the main control module 120 can accurately calculate key operating parameters such as the rotational speed and number of rotations of the center split shaft gear 144, thereby realizing real-time monitoring and control of the gear's operating status.

The water injection shaft gear also meshes with the center water distribution shaft gear. This application achieves stable rotation of the simulated hand-brewed trajectory by driving the gears in the actuator to rotate, replacing manual hand-brewed operation, making the extraction process more standardized and repeatable, and avoiding unstable extraction results caused by differences in manual operation. In addition, the signal acquisition module collects key data such as water injection volume and gear operation status in real time, providing accurate feedback to the main control module, enabling it to dynamically adjust the actions of the drive module and the actuator, such as controlling the number of water injection cycles and adjusting the water injection speed, further improving the accuracy of water injection and extraction.
