By performing the brewing adjustment processing on the brewing water injection state parameter and the preset water injection state parameter, it is convenient to determine the degree of change difference of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. The brewing water injection state parameter includes the remaining water volume of the coffee brewing and extracting device, and the remaining water volume of the water injection is the remaining hot water volume of the water nozzle of the coffee brewing and extracting device in the current watering stage, that is, the remaining water volume of the water injection is the currently available water volume of the coffee brewing and extracting device. By collecting the remaining water volume of the water injection, it is convenient to determine the water volume of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. By performing a leveling operation on the remaining water volume for water injection and the preset remaining water volume, the least square difference between the amount of water used to inject hot water into the coffee brewing extractor and the specified amount of hot water injected is obtained to reduce the error of the remaining water volume difference.

[0044] Furthermore, the sending of a variable speed watering disable signal to the water spray main control mechanism according to the injection adjustment amount to adjust the water injection mode of the coffee brewing and extracting device includes: detecting whether the water injection margin difference is greater than or equal to the preset margin difference; when the water injection margin difference is greater than or equal to the preset margin difference, sending a variable speed watering enable signal to the water spray main control mechanism to reduce the water injection speed of the water spray nozzle of the coffee brewing and extracting device from the center to the periphery in a spiral manner, wherein the rotation speed of the water spray nozzle satisfies the following relationship: V0=V1+K×(T0 / T1), V0 is the water injection speed of the water spray nozzle at the center position, V1 is the water injection speed of the water spray nozzle at the peripheral position, K is the degree of gradient reduction of the water spray nozzle deflection, T0 is the single water injection time of the water spray nozzle, and T1 is the gradient interval time of the water spray nozzle deflection. In this embodiment, the brewing adjustment amount is obtained based on the brewing water injection state parameter and the preset water injection state parameter. The brewing water injection state parameter is the water injection output data of the coffee brewing and extracting device, that is, the brewing water injection state parameter is the watering condition of the water nozzle of the coffee brewing and extracting device into the powder receiving funnel, that is, the brewing water injection state parameter corresponds to the state of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. By adjusting the brewing water injection state parameter, it is convenient to determine the watering working state of the water nozzle of the coffee brewing and extracting device. The preset water injection state parameter is the standard water injection output data of the coffee brewing and extracting device, that is, the preset water injection state parameter is the specified watering condition of the water nozzle of the coffee brewing and extracting device into the powder receiving funnel, that is, the preset water injection state parameter corresponds to the reference state of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. By performing the injection adjustment process on the brewing water injection state parameter and the preset water injection state parameter, it is convenient to determine the degree of change difference of the water spray nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. After obtaining the injection adjustment amount, the degree of difference in the watering state of the water spray nozzle of the coffee brewing and extracting device is determined, which is convenient for adjusting the water injection mode of the coffee brewing and extracting device to select a brewing method suitable for the current coffee powder, and effectively improve the degree of dissolution and mixing of coffee powder and hot water when simulating hand-brewed coffee. The brewing water injection state parameter includes the remaining water injection amount of the coffee brewing and extracting device, and the remaining water injection amount is the amount of hot water remaining in the water spray nozzle of the coffee brewing and extracting device in the current watering stage, that is, the remaining water injection amount is the currently available water injection amount of the coffee brewing and extracting device. By collecting the remaining water injection amount, it is convenient to determine the amount of water used by the water spray nozzle of the coffee brewing and extracting device to inject hot water into the powder receiving funnel. By performing a leveling operation on the remaining water volume for water injection and the preset remaining water volume, the least square difference between the amount of water used to inject hot water into the coffee brewing extractor and the specified amount of hot water injected is obtained to reduce the error of the remaining water volume difference.The water injection margin difference is greater than or equal to the preset margin difference, indicating that the water nozzle of the coffee brewing and extracting device has a large amount of hot water remaining in the current watering stage, that is, it indicates that the water nozzle of the coffee brewing and extracting device uses insufficient water to inject hot water into the powder receiving funnel, which also indicates that the coffee brewing and extracting device is at the initial end of the current watering stage. At this time, a variable speed watering enable signal is sent to the water spray main control mechanism to reduce the water injection speed of the water nozzle of the coffee brewing and extracting device from the center to the periphery in a spiral manner, so that the water nozzle of the coffee brewing and extracting device injects water with a spiral variable speed water flow, that is, the trajectory of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel is spiral, and the rotation speed of the water nozzle gradually decreases from the center position to the edge position of the powder receiving funnel, and the rotation speed of the inner and outer layer water nozzles satisfies the above relationship, which is convenient for injecting a spiral variable speed water flow into the coffee powder in the powder receiving funnel, so that the coffee powder in the powder receiving funnel is fully in contact with the hot water to achieve the effect of complete dissolution and mixing.

[0045] In another embodiment, when the water injection margin difference is less than the preset margin difference, a variable speed watering disabling signal is sent to the water spraying main control mechanism, so that the water spraying nozzle of the coffee brewing and extracting device stops injecting water and moves back to the center. In this embodiment, the water injection margin difference is less than the preset margin difference, indicating that the amount of hot water remaining in the water spraying nozzle of the coffee brewing and extracting device in the current watering stage is small, that is, it indicates that the water spraying nozzle of the coffee brewing and extracting device injects enough hot water into the powder receiving funnel, that is, it indicates that the coffee brewing and extracting device is at the end of the current watering stage, and the coffee powder in the powder receiving funnel has been fully dissolved. In order to avoid injecting too much hot water and affecting the extraction saturation of the coffee powder, a variable speed watering disabling signal is sent to the water spraying main control mechanism, so that the water spraying nozzle of the coffee brewing and extracting device stops injecting water and moves back to the center, so that the water spraying nozzle of the coffee brewing and extracting device no longer pours water into the powder receiving funnel, and the water spraying nozzle is re-moved to a position aligned with the center of the powder receiving funnel for the next water injection operation.

[0046] In one embodiment, the step of obtaining the brewing water injection state parameter of the coffee brewing and extracting device comprises: obtaining the remaining water injection stages of the coffee brewing and extracting device. In this embodiment, the brewing water injection state parameter is the water injection output data of the coffee brewing and extracting device, that is, the brewing water injection state parameter is the watering state of the water nozzle of the coffee brewing and extracting device into the powder receiving funnel, that is, the brewing water injection state parameter corresponds to the state of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. By analyzing the brewing water injection state parameter, it is convenient to determine the watering working state of the water nozzle of the coffee brewing and extracting device. The brewing water injection state parameter includes the remaining water injection stages of the coffee brewing and extracting device, and the remaining water injection stages are the remaining hot water injection stages of the water nozzle of the coffee brewing and extracting device in the current watering stage, that is, the remaining water injection stages are the current available water injection times of the coffee brewing and extracting device. By collecting the remaining water injection stages, it is convenient to determine the number of times the water nozzle of the coffee brewing and extracting device injects hot water into the powder receiving funnel.

[0047] Furthermore, the brewing water injection state parameter and the preset water injection state parameter are subjected to a brewing adjustment process to obtain a brewing adjustment amount, including: obtaining an adjustment between the remaining number of water injection sections and the preset remaining number of sections to obtain a residual water injection section difference. In this embodiment, the brewing water injection state parameter is the water injection output data of the coffee brewing and extracting device, that is, the brewing water injection state parameter is the water spraying condition of the water spray nozzle of the coffee brewing and extracting device into the powder receiving funnel, that is, the brewing water injection state parameter corresponds to the state of the water spray nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. By analyzing the brewing water injection state parameter, it is convenient to determine the watering working condition of the water spray nozzle of the coffee brewing and extracting device. The preset water injection state parameter is the standard water injection output data of the coffee brewing and extracting device, that is, the preset water injection state parameter is the specified watering condition of the water nozzle of the coffee brewing and extracting device into the powder receiving funnel, that is, the preset water injection state parameter corresponds to the reference state of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. By performing the brewing adjustment processing on the brewing water injection state parameter and the preset water injection state parameter, it is convenient to determine the degree of change difference of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. The brewing water injection state parameter includes the remaining water injection sections of the coffee brewing and extracting device, and the remaining water injection sections are the remaining hot water injection sections of the water nozzle of the coffee brewing and extracting device in the current watering stage, that is, the remaining water injection sections are the current available water injection times of the coffee brewing and extracting device. By collecting the remaining water injection sections, it is convenient to determine the number of times the water nozzle of the coffee brewing and extracting device injects hot water into the powder receiving funnel. By performing the adjustment operation on the remaining number of water injection stages and the preset remaining number of stages, the least square difference between the number of times the coffee brewing extractor injects hot water and the specified number of times hot water is injected is obtained to reduce the error of the water injection remaining stage difference.

[0048] Furthermore, the step of sending a variable speed watering disabling signal to the water spraying main control mechanism according to the flushing adjustment amount to adjust the water injection mode of the coffee brewing and extracting device includes: detecting whether the water injection residual difference is greater than or equal to a preset residual difference; when the water injection residual difference is less than the preset residual difference, sending a variable speed watering disabling signal to the water spraying main control mechanism to stop the water spraying nozzle of the coffee brewing and extracting device from injecting water and moving it back to the center. In this embodiment, the flushing adjustment amount is obtained based on the brewing water injection state parameter and the preset water injection state parameter, and the brewing water injection state parameter is the water injection output data of the coffee brewing and extracting device, that is, the brewing water injection state parameter is the water injection state of the water spraying nozzle of the coffee brewing and extracting device into the powder receiving funnel, that is, the brewing water injection state parameter corresponds to the state of the water spraying nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. By analyzing the brewing water injection state parameter, it is convenient to determine the watering working state of the water spraying nozzle of the coffee brewing and extracting device. The preset water injection state parameter is the standard water injection output data of the coffee brewing and extracting device, that is, the preset water injection state parameter is the specified watering condition of the water nozzle of the coffee brewing and extracting device into the powder receiving funnel, that is, the preset water injection state parameter corresponds to the reference state of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. By performing the brewing adjustment process on the brewing water injection state parameter and the preset water injection state parameter, it is convenient to determine the degree of difference in the water injection state of the water nozzle of the coffee brewing and extracting device injecting hot water into the powder receiving funnel. After obtaining the brewing adjustment amount, the degree of difference in the watering state of the water nozzle of the coffee brewing and extracting device is determined, which is convenient for adjusting the water injection mode of the coffee brewing and extracting device to select a brewing method suitable for the current coffee powder, effectively improving the degree of dissolution and mixing of coffee powder and hot water when simulating hand-brewed coffee. The brewing water injection state parameter includes the remaining water injection sections of the coffee brewing and extracting device, which is the remaining hot water injection sections of the water nozzle of the coffee brewing and extracting device in the current watering stage, that is, the remaining water injection sections are the current available water injection times of the coffee brewing and extracting device. By collecting the remaining water injection sections, it is convenient to determine the number of times the water nozzle of the coffee brewing and extracting device injects hot water into the powder receiving funnel. By adjusting the remaining water injection sections and the preset remaining sections, the least square difference between the number of times the coffee brewing and extracting device injects hot water and the specified number of times hot water is injected is obtained to reduce the error of the remaining water injection section difference.The water injection residual segment difference is less than the preset residual segment difference, indicating that the water nozzle of the coffee brewing and extracting device has a small number of remaining hot water injection segments in the current watering stage, that is, it indicates that the water nozzle of the coffee brewing and extracting device has injected a sufficient amount of hot water into the powder receiving funnel, which also indicates that the coffee brewing and extracting device is at the end of the current watering stage, and the coffee powder in the powder receiving funnel has been fully dissolved. In order to avoid affecting the extraction saturation of the coffee powder by injecting too much hot water, a variable speed watering disabling signal is sent to the water spraying main control mechanism to stop the water injection of the coffee brewing and extracting device and move it back to the center, so that the water nozzle of the coffee brewing and extracting device no longer pours water into the powder receiving funnel, and the water nozzle is moved back to a position aligned with the center of the powder receiving funnel to facilitate the next water injection operation.

[0049] In another embodiment, the water injection residual segment difference is greater than or equal to the preset residual segment difference, indicating that the water nozzle of the coffee brewing and extracting device has a large number of remaining hot water injection segments in the current watering stage, that is, it indicates that the water nozzle of the coffee brewing and extracting device has not injected hot water into the powder receiving funnel for an insufficient number of times, that is, it indicates that the coffee brewing and extracting device is at the initial end of the current watering stage. At this time, a variable speed watering enable signal is sent to the water spray main control mechanism to reduce the water injection speed of the water nozzle of the coffee brewing and extracting device from the center to the periphery in a spiral manner, so that the water nozzle of the coffee brewing and extracting device injects water with a spirally variable speed water flow, that is, the coffee brewing and extracting device is at the initial end of the current watering stage. The trajectory of the water nozzle of the device injecting hot water into the powder receiving funnel is spiral, and the rotation speed of the water nozzle gradually decreases from the center position to the edge position of the powder receiving funnel, and the rotation speed of the inner and outer layer water nozzles satisfies the following relationship: V0=V1+K×(T0 / T1), V0 is the water injection speed of the water nozzle at the center position, V1 is the water injection speed of the water nozzle at the peripheral position, K is the degree of gradient reduction of the deflection of the water nozzle, T0 is the single water injection time of the water nozzle, and T1 is the gradient interval time of the deflection of the water nozzle, which facilitates the injection of spiral variable speed water flow into the coffee powder in the powder receiving funnel, so that the coffee powder in the powder receiving funnel is fully in contact with the hot water, achieving the effect of complete dissolution and mixing.

[0050] In another embodiment, V0=2V1, that is, the water injection speed of the water nozzle at the center is twice the water injection speed of the water nozzle at the peripheral position. Among them, T1 is 200 milliseconds, T0 is 6 seconds, and K is 4 degrees, that is, it decreases evenly at intervals of 200 milliseconds, and each gradient decreases by 4 degrees. The total time for the water nozzle to go from the center to the periphery is 6 seconds, so that the water injection speed of the water nozzle at the center is 240 degrees / second, and the water injection speed of the water nozzle at the peripheral position is 120 degrees / second.

[0051] In the actual production process of imitation hand-brewed coffee, the degree of dissolution of coffee powder is not only affected by the water injection process, but also by the coarseness of the coffee powder itself. That is, only coffee powder that reaches a specified coarseness can be dissolved quickly and efficiently when water is injected. Otherwise, there will often be too much coffee residue in the powder receiving funnel, resulting in the produced coffee not meeting the consistency standard.

[0052] In order to avoid the situation where there are too many coffee residues in the powder receiving funnel after water injection, the method of obtaining the brewing water injection state parameters of the coffee brewing extractor includes the following steps:

[0053] Get the rotation speed of the coffee bean grinder's internal blade;

[0054] Detecting whether the rotation speed of the cutter head in the bean grinder is less than a preset rotation speed of the cutter head;

[0055] When the rotation speed of the cutter head in the coffee bean grinder is less than the preset cutter head rotation speed, a coffee bean grinding power increase signal is sent to the coffee bean grinding coarseness adjustment machine to increase the PWM duty cycle of the motor of the coffee bean grinder.

[0056] In this embodiment, the internal bean grinding head speed is the speed of the internal bean grinding head of the coffee bean grinder when grinding beans. Specifically, the internal bean grinding head and the external bean grinding head of the coffee bean grinder are nested with each other, and the internal bean grinding head of the coffee bean grinder is connected to the rotating shaft of the bean grinding motor, so that the internal bean grinding head and the external bean grinding head of the coffee bean grinder can quickly grind the coffee beans. The preset head speed is the specified grinding speed of the internal bean grinding head of the coffee bean grinder, that is, the preset head speed corresponds to the standard coarseness of the ground coffee powder, that is, different coarsenesses of coffee powder correspond to different preset head speeds. The internal bean grinding head speed is less than the preset head speed, indicating that the internal bean grinding head of the coffee bean grinder rotates too slowly when grinding beans, that is, the coffee powder particles ground by the coffee bean grinder at the current grinding speed are too large, that is, the coffee powder ground by the coffee bean grinder is too coarse. At this time, a grinding power increase signal is sent to the grinding coarseness adjustment machine to increase the PWM duty cycle of the motor of the coffee bean grinder. Specifically, by increasing the duty cycle of the PWM control signal of the motor of the coffee bean grinder, the output power of the motor of the coffee bean grinder is increased, thereby increasing the grinding speed of the coffee bean grinder, so as to facilitate adjusting the grinding speed of the coffee bean grinder to the required speed to meet the coffee powder of specified coarseness.

[0057] Furthermore, the detecting whether the rotation speed of the cutter head in the bean grinder is less than a preset rotation speed of the cutter head further includes:

[0058] When the rotation speed of the cutter head in the coffee bean grinder is greater than the preset cutter head rotation speed, obtaining the coffee bean grinder grinding time;

[0059] Detecting whether the grinding time is greater than or equal to a preset time;

[0060] When the bean grinding time is greater than or equal to the preset time, detecting whether the rotation speed of the bean grinding cutter head is greater than or equal to the idling rotation speed;

[0061] When the rotation speed of the bean grinder is greater than or equal to the idling rotation speed, a bean grinding water injection switching signal is sent to the bean grinding coarseness adjustment machine to stop grinding beans, and step S100 is executed.

[0062] In this embodiment, the rotation speed of the inner bean grinding head is greater than the preset rotation speed of the blade head, indicating that the rotation speed of the inner bean grinding head of the coffee bean grinder is too fast when grinding beans, that is, the coffee powder particles ground by the coffee bean grinder at the current grinding speed are too small, that is, the coffee powder ground by the coffee bean grinder is too fine. At this time, the rotation speed of the inner bean grinding head of the coffee bean grinder is too fast relative to the rotation speed of the outer bean grinding head, and there is idling, that is, there is a situation where the coffee beans have been ground. Before detecting idling, the grinding time needs to be determined. If the grinding time is greater than or equal to the preset time, it indicates that the grinding process of the coffee bean grinder is close to the end, and the inner bean grinding head of the coffee bean grinder is very likely to be idling. To this end, by detecting the relationship between the rotation speed of the inner bean grinder and the idling rotation speed, the idling rotation speed is the rotation speed of the inner bean grinder of the coffee bean grinder when idling, that is, the idling rotation speed corresponds to the rotation speed of the inner bean grinder when there are no coffee beans to be ground in the coffee bean grinder, and specifically, the idling rotation speed is twice the preset blade rotation speed. The rotation speed of the inner bean grinder is greater than or equal to the idling rotation speed, indicating that the inner bean grinder of the coffee bean grinder is currently idling, that is, indicating that there are no coffee beans to be ground in the coffee bean grinder, at this time, a grinding bean water injection switching signal is sent to the grinding bean coarseness adjustment machine, so that the inner bean grinder of the coffee bean grinder stops rotating to reduce power consumption, and the water injection operation is also started synchronously, for example, the powder receiving funnel is transferred from the grinding bean station to the water injection station, so as to facilitate the switching between grinding and water injection, so as to facilitate the rapid brewing of coffee beans after the beans are ground into powder.

[0063] In another embodiment, when the rotation speed of the bean grinder inner blade head is less than the idling speed, a bean grinder power reduction signal is sent to the bean grinder coarseness adjustment machine to reduce the PWM duty cycle of the motor of the coffee bean grinder. In this embodiment, the rotation speed of the bean grinder inner blade head is less than the idling speed, indicating that the bean grinder inner blade head of the coffee bean grinder is not idling at present and is still grinding beans, and the rotation speed of the bean grinder inner blade head of the coffee bean grinder is too fast. At this time, a bean grinder power reduction signal is sent to the bean grinder coarseness adjustment machine to reduce the PWM duty cycle of the motor of the coffee bean grinder. Specifically, by reducing the duty cycle of the PWM control signal of the motor of the coffee bean grinder, the output power of the motor of the coffee bean grinder is reduced, so that the grinding speed of the coffee bean grinder is steadily reduced, so as to facilitate the adjustment of the grinding speed of the coffee bean grinder to the required speed to meet the specified coarseness of the coffee powder.

[0064] In another embodiment, when the rotation speed of the cutter head in the grinder is equal to the preset rotation speed of the cutter head, the current power of the motor of the coffee bean grinder is maintained. At this time, the grinding speed of the coffee bean grinder corresponds to the coffee powder of the specified coarseness, and the rotation speed does not need to be adjusted, and the current output power can be maintained.

[0065] In another embodiment, when the bean grinding time is less than the preset time, the current bean grinding operation is continued.

[0066] The above-mentioned various preset variables are all set in the database for timely retrieval, and different preset variables are placed in different storage units, that is, in different storage stacks. Moreover, the rotation speed of the cutter head in the grinder and the grinding time can be collected through corresponding detectors, for example, through the grinding speed sensor and the grinding timer in the grinding and punching collection module.

[0068] In this embodiment, after the grinding and brewing collection module collects the brewing water injection state parameters, the execution status of the hot water injection operation of the coffee brewing extractor is determined, and then the grinding and brewing processing module compares the brewing water injection state parameters with the standard water injection parameters to facilitate determining the difference between the current hot water injection operation execution status of the coffee brewing extractor and the specified hot water injection operation. Finally, the grinding and brewing control module optimizes and adjusts the water injection mode of the coffee brewing extractor according to the above difference value, so as to facilitate the adjustment of the variable speed watering method of the coffee brewing extractor to select a brewing method suitable for the current coffee powder, thereby effectively improving the degree of dissolution and mixing of coffee powder and hot water when simulating hand-brewed coffee.
