[0020] Embodiment 1 The embodiment of the present application provides a simulation hand-pouring control method, and specifically, refer to Figure 1 , the method comprises steps S110-S140. The method is applied to the simulation hand-pouring control device 200 as Figure 2 described, the simulation hand-pouring control device 200 comprises a signal acquisition module 210, a main control module 220 and a driving module 230, the main control module 220 is electrically connected with the signal acquisition module 210 and the driving module 230 respectively, and the driving module 230 is further electrically connected with an executing mechanism 300, the executing mechanism 300 comprises a motor gear 301, a driving gear 302, a water injection shaft gear 303 and a middle water distribution shaft gear 304, the motor gear 301 is engaged with the driving gear 302, the output end of the driving gear 302 is connected with the input end of the water injection shaft gear 303, and the water injection shaft gear 303 is further engaged with the middle water distribution shaft gear 304.

[0021] Please combine Figure 3 , Figure 3 with the exploded view of the executing mechanism 300 provided by the embodiment of the present application. The executing mechanism 300 comprises a motor gear 301, a driving gear 302, a water injection shaft gear 303 and a middle water distribution shaft gear 304, wherein the motor gear 301 is engaged with the driving gear 302, the output end of the driving gear 302 is connected with the input end of the water injection shaft gear, and the driving gear 302 drives the water injection shaft gear 303 to rotate in the rotating process of the driving gear 302, and the water injection shaft gear 303 is engaged with the middle water distribution shaft gear 304. The middle water distribution shaft 306 is sleeved in the reserved hole of the middle water distribution shaft gear 304.

[0022] It can be understood that when the driving module 230 drives the motor gear 301 to rotate, the driving gear 302 engaged with the motor gear 301 starts to rotate and drives the water injection shaft gear 303 to rotate, and because the water injection shaft gear 303 is engaged with the middle water distribution shaft gear 304, the middle water distribution shaft gear 304 revolves around the water injection shaft 305 while rotating, so that the middle water distribution shaft 306 sleeved in the reserved hole of the water injection shaft gear 303 forms a rotating track as Figure 4 shown.

[0023] In step S110, the main control module 220 acquires preset water injection parameters and a preset gear ratio, determines a target rotating speed according to the preset water injection parameters, or determines the target rotating speed according to the preset water injection parameters and the preset gear ratio, and sends a driving control signal to the driving module 230 according to the target rotating speed.

[0024] In the embodiment, the preset gear ratio includes gear ratios of the water injection shaft gear 303 and the middle water distribution shaft gear 304, and gear ratios of the motor gear 301 and the drive gear 302. It can be understood that if the gear ratio of the motor gear 301 and the drive gear 302 is 1:M, the number of turns of the motor gear 301 and the drive gear 302 is M:1, that is, the drive gear 302 rotates one turn when the motor gear 301 rotates M turns. If the gear ratio of the water injection shaft gear 303 and the middle water distribution shaft gear 304 is 1:n, the gear ratio of the water injection shaft gear 303 and the middle water distribution shaft gear 304 is n:1, that is, the middle water distribution shaft gear 304 rotates one turn when the water injection shaft gear 303 rotates n turns.

[0025] The preset water injection parameters include a preset water injection time and a preset number of turns, or include a preset water injection time and a preset target position. Further, the target rotating speed of the motor gear 301 can be determined according to the preset water injection time and the preset target position, or the target rotating speed of the motor gear 301 can be determined according to the preset water injection time, the preset number of turns, and the preset gear ratio.

[0026] In an embodiment, the actuator 300 further includes a middle water distribution shaft 306, which is sleeved in a reserved hole of the middle water distribution shaft gear 304, and rotates according to a preset brewing track when the middle water distribution shaft gear 304 rotates.

[0027] Please refer to Figure 3 When the middle water distribution shaft gear 304 rotates under the driving of the drive gear 302 and the water injection shaft gear 303, the middle water distribution shaft 306 is driven synchronously by the middle water distribution shaft gear 304 due to the direct connection between the middle water distribution shaft 306 and the middle water distribution shaft gear 304, and rotates according to a preset hand-brewed coffee brewing track. The hand-brewed coffee brewing track can be seen in Figure 4 .

[0028] In an embodiment, please refer to Figure 5 , before the master control module 220 acquires the preset water injection parameters and the preset gear ratio, it further includes steps S150-S180.

[0029] In step S150, the signal acquisition module 210 acquires a first initial position signal and a second initial position signal, and sends the first initial position signal and the second initial position signal to the master control module 220.

[0030] In the embodiment, the signal acquisition module 210 includes a microswitch. The specific installation position of the microswitch can be combined with Figure 3 and Figure 6Specifically, the micro switch comprises a contact 307 mounted on the driving gear 302, and rotation of the driving gear 302 drives the contact 307 to rotate. When the contact 307 is rotated to below the top cover of the driving gear 302 by the driving gear 302, the contact 307 is connected, and when the contact 307 is rotated to the initial position of the contact 307 by the driving gear 302, the contact 307 is disconnected due to the extrusion of the top cover of the driving gear 302, and at this time, the micro switch receives a preset level signal.

[0031] The signal acquisition module 210 further comprises a dry spring 309 assembly, and the specific installation position of the dry spring 309 assembly can be combined with Figure 3 and Figure 7 Specifically, the dry spring 309 assembly comprises a dry spring 309 and a magnet 308, wherein the magnet 308 is mounted on the top cover of the middle water shaft gear 304 and cooperates with the dry spring 309 mounted on the fixed bottom cover. Specifically, when the middle water shaft gear 304 rotates, the magnet 308 rotates together, and when the magnet 308 is not directly below the dry spring 309, the dry spring 309 is disconnected; when the magnet 308 is directly below the dry spring 309, i.e., the magnet 308 is in the initial position of the magnet 308, the dry spring 309 is connected, and at this time, the dry spring 309 assembly receives a preset level signal.

[0032] It can be understood that the signal acquisition module 210 obtains a first initial position signal through the micro switch and a second initial position signal through the dry spring 309 assembly, judges whether the contact 307 is in the initial position of the contact 307 according to the first initial position signal, and when the contact 307 is in the initial position of the contact 307, it can be considered that the rotation angle of the driving gear 302 is a first preset angle, and preferably, the first preset angle is zero. According to the second initial position signal, it is judged whether the magnet 308 is in the initial position of the magnet 308, and when the magnet 308 is in the initial position, it can be considered that the rotation angle of the middle water shaft gear 304 is a first preset angle, and preferably, the first preset angle is zero.

[0033] In step S160, the main control module 220 judges whether the initial rotation angle of the driving gear 302 is a first preset angle according to the first initial position signal, and judges whether the initial rotation angle of the middle water shaft gear 304 is a second preset angle according to the second initial position signal.

[0034] It can be understood that after receiving the first initial position signal and the second initial position signal sent by the signal acquisition module 210, the main control module 220 will make angle judgments based on the two types of signals respectively: on the one hand, based on the first initial position signal, it analyzes and confirms whether the current initial rotation angle of the drive gear 302 is consistent with the first preset angle; on the other hand, based on the second initial position signal, it analyzes and confirms whether the current initial rotation angle of the middle water shaft gear 304 is consistent with the second preset angle, and through the judgment of these two dimensions, it provides decision basis for whether to start the initialization calibration process subsequently.

[0035] In an embodiment, the step of judging whether the initial rotation angle of the drive gear 302 is the first preset angle according to the first initial position signal comprises: judging whether the first initial position signal is a preset level signal, and if so, determining that the initial rotation angle of the drive gear 302 is the first preset angle. The step of judging whether the initial rotation angle of the middle water shaft gear 304 is the second preset angle according to the second initial position signal comprises: judging whether the second initial position signal is the preset level signal, and if so, determining that the initial rotation angle of the middle water shaft gear 304 is the second preset angle.

[0036] In this embodiment, the preset level signal can be a high level signal or a low level signal, which is set according to actual needs.

[0037] Step S170: If the initial rotation angle of the drive gear 302 is not the first preset angle, and / or the initial rotation angle of the middle water shaft gear 304 is not the second preset angle, an initialization signal is sent to the drive module 230.

[0038] It can be understood that when it is detected that the initial rotation angle of the drive gear 302 does not reach the first preset angle, or the initial rotation angle of the middle water shaft gear 304 does not reach the second preset angle, or the initial rotation angles of both gears do not reach the respective preset angles, the main control module 220 will send an initialization signal for starting position calibration to the drive module 230 to trigger the subsequent gear reset operation, so as to ensure that each component returns to the standard initial position.

[0039] Step S180: When receiving the initialization signal, the drive module 230 drives the motor gear 301 to rotate in turn to drive the drive gear 302, the water injection shaft gear 303 and the middle water shaft gear 304, so that the drive gear 302 rotates to the first preset angle, and the middle water shaft gear 304 rotates to the second preset angle.

[0040] In the embodiment, when the driving module 230 receives the initialization signal sent by the master module 220, the motor gear 301 is driven to rotate. Since the motor gear 301 and the driving gear 302 are in meshing connection, the rotation of the motor gear 301 can directly drive the driving gear 302 to rotate synchronously. Then, since the output end of the driving gear 302 is connected with the input end of the water injection shaft gear 303, the rotation of the driving gear 302 can be further transmitted to the water injection shaft gear 303, so as to drive the water injection shaft gear 303 to rotate. Since the water injection shaft gear 303 is in meshing connection with the middle water distribution shaft gear 304, the rotation of the water injection shaft gear 303 can drive the middle water distribution shaft gear 304 to rotate. Through the sequential linkage transmission of the gears, the driving gear 302 is finally driven to rotate to a first preset angle, and the middle water distribution shaft gear 304 is simultaneously driven to rotate to a second preset angle, so as to complete the initial position calibration of the two core gears.

[0041] In step S120, when receiving the driving control signal, the driving module 230 drives the motor gear 301 to rotate at the target rotating speed, and sequentially drives the driving gear 302, the water injection shaft gear 303 and the middle water distribution shaft gear 304 to rotate.

[0042] In the embodiment, when the driving module 230 receives the driving control signal sent by the master module 220, the motor gear 301 in the driving mechanism 300 is driven to rotate at the target rotating speed. Since the motor gear 301 and the driving gear 302 are in meshing connection, the rotation of the motor gear 301 can directly drive the driving gear 302 to rotate synchronously. Since the output end of the driving gear 302 is connected with the input end of the water injection shaft gear 303, the rotation of the driving gear 302 can be further transmitted to the water injection shaft gear 303, so as to drive the water injection shaft gear 303 to rotate. Since the water injection shaft gear 303 is in meshing connection with the middle water distribution shaft gear 304, the rotation of the water injection shaft gear 303 can finally drive the middle water distribution shaft gear 304 to rotate, so as to complete the process from the start of the driving module 230 to the sequential linkage rotation of the core gears.

[0043] In step S130, the signal acquisition module acquires a first position signal and sends the first position signal to the master module.

[0044] In the embodiment, when the master module 220 receives the first position signal sent by the signal acquisition module 210, such as the position data fed back by the micro switch, the master module 220 can analyze and process the signal. According to the preset gear transmission characteristics or the corresponding relationship between the position and the angle, the position signal can be converted into a specific angle value, so as to determine the rotating angle of the driving gear 302.

[0045] Step S140, the host module 220 determines the current rotation angle of the drive gear 302 according to the first position signal, judges whether the current rotation angle meets the preset target condition, if yes, determines that the current brewing is completed.

[0046] In an embodiment, the preset water injection parameter includes a preset water injection time and a preset target position, and the determining the target rotating speed according to the preset water injection parameter includes: determining a target rotation angle of the drive gear 302 according to the preset target position; and determining the target rotating speed according to the target rotation angle and the preset water injection time. The judging whether the current rotation angle meets the preset target condition includes: judging whether the drive gear 302 rotates to the preset target position according to the current rotation angle, if yes, determining that the current rotation angle meets the preset target condition.

[0047] In the embodiment, the target rotation angle is determined according to the preset target position, the drive gear 302 needs to rotate to the preset target position, and the target rotating speed is calculated according to the target rotation angle and the preset water injection time, specifically, the target rotating speed = target rotation angle ÷ preset water injection time. The judging whether the current rotation angle meets the preset target condition is to judge whether the drive gear 302 has rotated to the preset target position according to the current rotation angle, if yes, it is determined that the current rotation angle meets the preset target condition.

[0048] In an embodiment, the preset water injection parameter includes a preset water injection time and a preset water injection circle number, and the determining the target rotating speed according to the preset water injection parameter and the preset gear ratio includes: determining the target rotating speed according to the preset water injection time, the preset water injection circle number and the gear ratio between the gears. The judging whether the current rotation angle meets the preset target condition includes: determining a current rotation circle number of the middle water distribution shaft gear 304 according to the current rotation angle and the preset gear ratio, if the current rotation circle number is the preset water injection circle number, it is determined that the current rotation angle meets the preset target condition.

[0049] In the embodiment, according to the gear ratio between each gear, the relationship between the current rotation angle of the driving gear 302 and the rotation number of the middle water shaft gear 304 can be determined. When it is determined that the middle water shaft gear 304 needs to rotate a preset water injection number of turns within a preset water injection time, if the gear ratio between the motor gear 301 and the driving gear 302 is 1:M, and the gear ratio between the water injection shaft gear 303 and the middle water shaft gear 304 is 1:n, then the target rotation speed of the motor gear 301 can be obtained according to the following formula: target rotation speed=M×n×P / T, wherein P represents the preset water injection number of turns, and T represents the preset water injection time. When it is determined whether the current rotation angle of the driving gear 302 meets the preset target condition, the actual current rotation number of turns of the middle water shaft gear 304 is first derived according to the current rotation angle of the driving gear 302 and the preset gear ratio between each gear. If the current rotation number of turns is consistent with the preset water injection number of turns, it is determined that the current rotation angle of the driving gear 302 meets the preset target condition.

[0050] In an embodiment, the determining that the current brewing is completed further includes: the main control module 220 sending a stop control signal to the driving module 230; and when receiving the stop control signal, the driving module 230 driving the motor gear 301 to rotate in turn to drive the driving gear 302, the water injection shaft gear 303 and the middle water shaft gear 304 to rotate, so that the driving gear 302 returns to the first preset angle and the middle water shaft gear 304 returns to the second preset angle.

[0051] In the embodiment, after determining that the current brewing process is completed, the main control module 220 sends a stop control signal to the driving module 230; and when the driving module 230 receives the signal, the driving module 230 drives the motor gear 301 to rotate, and then drives the driving gear 302, the water injection shaft gear 303 and the middle water shaft gear 304 to rotate in turn, so that the driving gear 302 returns to the first preset angle and the middle water shaft gear 304 returns to the second preset angle, and the component resetting operation after the whole brewing is completed is completed.

[0052] In an embodiment, the actuator 300 further includes a water injection pump, and the method further includes: the main control module 220 acquiring a preset water injection amount and a preset water injection time, determining a water injection speed according to the preset water injection amount and the preset water injection time, and sending a water injection control signal to the driving module 230 according to the water injection speed; and when receiving the water injection control signal, the driving module 230 drives the water injection pump to inject water at the water injection speed.
