Description

Technical Field

[0001] This application relates to the field of beverage preparation equipment technology, and in particular to a control method for beverage preparation equipment and beverage preparation equipment. Background Technology

[0002] Currently, chain beverage stores offer dozens of beverage options. Beverage recipes require staff to memorize them, and juice mixing relies on spoons and experience, making the process cumbersome and prone to significant flavor variations. This fails to meet the demands of fast service and consistent taste in modern chain stores. Existing automatic beverage machines do not consider physical parameters such as juice density, causing the pump to use the same operating parameters for different juices. This results in low extraction accuracy; for example, insufficient extraction of thick juices and excessive extraction of thin juices, leading to inconsistent juice output, waste, uneven taste, and a poor user experience. Summary of the Invention

[0003] To address the aforementioned technical problems in the existing technology, this application provides a control method and beverage preparation equipment, which can accurately control the working parameters of the raw material conveying pump based on the physical parameter information of different raw materials, thereby improving the extraction accuracy of the raw material conveying pump for different raw materials and achieving stable extraction of raw material quantity, stable formula ratio, and consistent taste.

[0004] This application provides a control method for a beverage preparation device. The beverage preparation device includes a control unit and a storage unit, a barcode scanning unit, a conveying device, and a raw material storage device, all communicatively connected to the control unit. The raw material storage device includes multiple containers for storing different raw materials. The conveying device includes multiple raw material outlet pipes and raw material conveying pumps corresponding to the multiple containers. The raw material conveying pumps supply raw materials to beverage cups through the corresponding raw material outlet pipes. The control method includes: The barcode scanning unit identifies the identification code on each container to obtain the physical parameter information of the raw material inside the corresponding container; wherein, the storage unit stores the corresponding identification code and physical parameter information in association; The control unit determines the corresponding operating parameters of the raw material conveying pump based on the parameter information. The control unit obtains an operation instruction for selecting a target formula from multiple formula information; wherein, the storage unit stores multiple formula information corresponding to different raw material ratios; The control unit controls multiple raw material delivery pumps to simultaneously supply raw materials to the beverage cup based on the target formula information and the corresponding operating parameters of the raw material delivery pumps. This method enables precise control of the operating parameters of the raw material delivery pumps according to the physical parameters of different raw materials, improving the extraction accuracy of the pumps for different raw materials and achieving stable extraction quantities, stable formula ratios, and consistent flavor.

[0005] In some embodiments, the control method further includes: When multiple raw material delivery pumps are controlled to simultaneously supply raw materials to the beverage cup, the pipeline information of the corresponding raw material outflow pipe is detected by the pipeline sensor of the delivery device; wherein, each raw material outflow pipe is provided with a pipeline sensor, and the pipeline information is used to at least characterize whether there is a shortage of material in the corresponding raw material outflow pipe; The control unit controls the operation of the raw material delivery pump based on the pipeline information. In this way, the pipeline information of the corresponding raw material outlet pipe can be detected by the pipeline sensor of the delivery device to accurately detect whether there is a shortage of material in the raw material outlet pipe, ensuring that the raw material delivery pump accurately delivers a fixed amount of raw material during operation. This achieves accurate detection of the pipeline information of the raw material outlet pipe, thereby further achieving accurate material discharge and ensuring discharge stability.

[0006] In some embodiments, the beverage preparation device further includes a position sensor communicatively connected to the control unit, and the method further includes: After receiving the target recipe information, the control unit obtains detection information on whether the beverage cup is in the correct position as detected by the position sensor. When the detection information indicates that the beverage cup is in the correct position, multiple ingredient delivery pumps are controlled to simultaneously supply ingredients to the beverage cup. In this way, the position of the beverage cup can be accurately detected by a position sensor, and multiple ingredient delivery pumps are only controlled to supply ingredients to the beverage cup after the cup is in position. This ensures that the ingredients flowing from the dispensing device accurately fall into the beverage cup, avoiding the problem of the ingredient delivery pumps mistakenly discharging ingredients before the beverage cup is in position.

[0007] In some embodiments, the beverage preparation device further includes a tray and a weighing unit communicatively connected to the control unit, the weighing unit being used to weigh the items on the tray, the beverage cup being positioned on the tray in the positioned state, and the control method further including: When the detection information indicates that the beverage cup is in the positioned state, the initial weight information of the beverage cup is measured via the weighing unit; When multiple raw material delivery pumps simultaneously supply raw materials to the beverage cup, the weighing unit weighs the corresponding beverage cup and the raw materials inside it in real time. When the difference between the real-time weight information and the initial weight information reaches a preset threshold, the control unit controls the delivery pump to stop working. Thus, the weighing unit can accurately weigh the initial weight of the beverage cup when it is in its positioned state, and can also accurately weigh the beverage cup and its contents in real time after dispensing, thereby precisely weighing the discharged ingredients.

[0008] In some embodiments, the control unit controls the operation of the raw material delivery pump based on the pipeline information, specifically including: When the pipeline information indicates a material shortage in the corresponding raw material outflow pipe, the duration of the material shortage in the raw material outflow pipe is determined. The control unit controls the corresponding delivery pump to deliver the appropriate raw materials to the beverage cup based on the duration of material shortage. In this way, the duration of material shortage in the material outflow pipe can be determined, and the replenishment time can be compensated based on the material shortage duration, thereby replenishing the beverage cup with the appropriate raw materials and further ensuring precise control of the dispensing ratio.

[0009] In some embodiments, the control method further includes: When the pipeline sensor continuously detects a shortage of material in the raw material outflow pipe, it determines that the corresponding container is also short of material and generates a notification message to the user indicating that the material is low. In this way, the pipeline sensor can monitor the material shortage in the outflow pipe in real time, promptly alerting the user when the container is low on material.

[0010] This application embodiment also provides a beverage preparation device, including a control unit and a storage unit, a barcode scanning unit, a conveying device, and a raw material storage device, all communicatively connected to the control unit. The raw material storage device includes multiple containers for storing different raw materials. The conveying device includes multiple raw material outlet pipes and raw material delivery pumps corresponding to the multiple containers. The raw material delivery pumps supply raw materials to a beverage cup through the corresponding raw material outlet pipes. The barcode scanning unit is used to identify the identification codes on each container to obtain the physical parameter information of the raw materials in the corresponding container. The storage unit stores the corresponding identification codes and physical parameter information in association. The control unit is used to determine the operating parameters of the corresponding raw material delivery pump based on the parameter information. The control unit is used to obtain the operation instruction of the target formula information selected from multiple formula information. The storage unit stores multiple formula information corresponding to different raw material ratios. The control unit is used to control the multiple raw material delivery pumps to simultaneously supply raw materials to the beverage cup based on the target formula information and the corresponding operating parameters of the raw material delivery pumps. The beverage preparation equipment described above can accurately control the working parameters of the raw material delivery pump based on the physical parameter information of different raw materials, thereby improving the extraction accuracy of the raw material delivery pump for different raw materials and achieving stable extraction of raw material quantity, stable formula ratio, and consistent taste.

[0011] In some embodiments, the beverage preparation equipment further includes a juice dispensing device disposed above the beverage cup. The juice dispensing device includes a dispensing valve body communicating with the raw material outlet pipe. The dispensing valve body has multiple flexible opening and closing nozzles for dispensing different raw materials separately. When raw materials flow towards the dispensing valve body, the flexible opening and closing nozzles switch from a closed state to an open state under pressure. In this way, multiple dispensing points can be simultaneously dispensed through the dispensing valve body, avoiding the problem of mixing different raw materials. Furthermore, the structural design of the flexible opening and closing nozzles can solve the problem of dripping from the pipeline after the raw material delivery pump stops working, further ensuring the accurate realization of the formula and avoiding the problem of mixing different raw materials. In some embodiments, the juice dispensing device further includes a discharge pipe and a mounting bracket. The discharge pipe is configured to correspond one-to-one with the resilient opening and closing nozzle, and the discharge end of the discharge pipe abuts against the inner wall surface of the liquid dispensing valve body. The mounting bracket includes a first bracket and a second bracket magnetically connected. The first bracket houses the discharge pipe, and the second bracket houses the liquid dispensing valve body. Thus, the magnetically connected first and second brackets facilitate the removal and disassembly of the liquid dispensing valve body.

[0012] In some embodiments, the beverage preparation equipment further includes a cleaning device, and the conveying device includes multiple raw material inflow pipes. These raw material inflow pipes are connected to each of the containers via a raw material conveying pump and a raw material outflow pipe. The cleaning device includes a cleaning pump and multiple cleaning pipelines connected to the cleaning pump. Each of the multiple cleaning pipelines is connected to a corresponding raw material inflow pipe. The cleaning pump is activated under the control of the control unit to provide cleaning liquid to each of the raw material inflow and outflow pipes. Thus, the cleaning device enables simultaneous cleaning of all the raw material inflow and outflow pipes; that is, one cleaning device can clean all the raw material inflow and outflow pipes, achieving daily cleaning and maintenance of the pipelines and ensuring the food safety of the raw materials.

[0013] Compared with existing technologies, the beneficial effects of this application's embodiments are as follows: This application uses multiple containers for storing different raw materials, each bearing an identification code. A scanning unit can obtain the physical parameter information of the corresponding raw material within the container by scanning the code. A storage unit stores the corresponding identification code and physical parameter information in association. Then, a control unit determines the operating parameters of the corresponding raw material delivery pump based on the parameter information. This allows for precise control of the raw material delivery pump's operating parameters based on the physical parameter information of different raw materials, improving the pump's extraction accuracy for different raw materials. It achieves stable extraction quantities, stable formula ratios, and consistent taste, improving the user experience, achieving precise dispensing, and eliminating the need for manual intervention. It is highly intelligent and simplifies user operation. Furthermore, multiple raw material delivery pumps simultaneously supplying raw materials to the beverage cup can achieve simultaneous juice extraction through multiple pipelines, improving beverage preparation efficiency.

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] This application provides a control method for beverage preparation equipment. For example... Figures 1 to 5As shown, the beverage preparation equipment includes a control unit 1 and a storage unit, a barcode scanning unit 2, a conveying device 4, and a raw material storage device 5, which are respectively communicatively connected to the control unit 1. The raw material storage device 5 includes multiple containers 51 for storing different raw materials. The conveying device 4 includes multiple raw material outlet pipes 41 and raw material conveying pumps 42 respectively corresponding to the multiple containers 51. The raw material conveying pumps 42 provide raw materials to the beverage cup 10 through the corresponding raw material outlet pipes 41.

[0019] like Figure 6 As shown, the control method includes steps S101 to S104.

[0020] Step S101: The barcode scanning unit 2 identifies the identification code on each of the containers 51 to obtain the physical parameter information of the raw materials in the corresponding containers 51; wherein, the storage unit stores the corresponding identification code and physical parameter information in association.

[0021] Step S102: The control unit 1 determines the corresponding operating parameters of the raw material delivery pump 42 based on the parameter information.

[0022] Step S013: Obtain an operation instruction from the control unit 1 to select the target formula information from multiple formula information; wherein, the storage unit stores multiple formula information corresponding to different raw material ratios. Multiple formula information can be stored in the storage unit, and the control unit 1 can obtain and process the data stored in the storage unit.

[0023] Step S104: The control unit 1 controls multiple raw material delivery pumps 42 to simultaneously supply raw materials to the beverage cup 10 based on the target formula information and the corresponding operating parameters of the raw material delivery pump 42.

[0024] It should be noted that the control unit 1 can be constructed using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0025] like Figure 1As shown, the beverage preparation equipment described above may further include a smart terminal 11 electrically connected to the control unit 1. The control unit 1 can receive operation commands input by the user on the smart terminal 11. The smart terminal 11 may include a touch screen located at the top front of the chassis, and a barcode scanning unit 2 located behind the touch screen. The glass in front of the barcode scanning unit 2 is transparent to allow it to receive external information. Users can perform operations such as beverage preparation, pipeline cleaning, and information recording by inputting commands through the touch screen.

[0026] The touch screen of the aforementioned smart terminal 11 is located in the front interactive area of ​​the beverage preparation equipment. The touch screen has multiple virtual recipe buttons, each corresponding to a set of preset multi-flavor recipes. The recipes record the raw materials required for different flavor beverages, such as recipe 1 corresponding to the weight data of raw material A, raw material B, raw material C, ..., raw material N.

[0027] The aforementioned scanning unit 2 scans the identification code on the container 51, enabling the input of the raw material's physical parameter information. This allows for the calculation of information such as the number of cups required for different formulations, the discharging time, and the rotational speed of the raw material conveying pump 42 during discharging. Furthermore, the raw material storage device 5 has multiple storage slots 53 on its storage rack 52, with each container 51 correspondingly stored within one of these slots. The storage unit stores the corresponding container 51 and storage slot 53 in a linked manner, allowing for precise extraction of the raw material from the container 51 placed in the designated storage slot 53.

[0028] The physical parameter information of the aforementioned raw materials may include at least one of the following: raw material type information, density information, viscosity information, and volume information.

[0029] The beverage cup 10 can be affixed with a unique code, which can correspond to different recipe information. The scanning unit 2 can obtain the recipe information corresponding to the beverage cup 10 after reading the unique code. The control unit 1 can then use this information to control the corresponding raw material delivery pump 42 to prepare the beverage of the corresponding flavor, eliminating the need for manual button selection. In this way, the beverage preparation equipment can have both touch-sensitive button recipe selection and automatic recipe reading via barcode scanning, offering the advantages of simple operation and ease of use for users.

[0030] The aforementioned raw material storage device 5 can be placed in the insulation layer for refrigerated and constant temperature storage. The container 51 of the raw material storage device 5 contains raw materials of a rated capacity. The container 51 has a detachable cover and a discharge port that communicates with the outside. The discharge port is connected to the suction end of the raw material conveying pump 42. The physical parameter information such as the type, density, viscosity, and volume of the raw materials in the raw material storage device 5 can be obtained through the barcode scanning unit 2.

[0031] Understandably, after the scanning unit 2 identifies the identification code on each container 51, the container 51 is placed into the corresponding storage slot 53 on the storage rack 52, thereby placing each container 51 into a different storage slot 53 to stably place each container 51 and accurately position each container 51.

[0032] After the scanning unit 2 identifies the identification code on each container 51, the storage unit stores the corresponding identification code, physical parameter information, and the location of the corresponding storage slot 53 of this container 51 in association. This enables the control unit 1 to accurately control the discharge of the corresponding raw materials in the formula when it receives an operation instruction to prepare a beverage, thus achieving precise control over the discharge of raw materials.

[0033] The aforementioned target formula information can be understood as one of multiple formula information. It can be selected by the user or obtained by recognizing the unique code on the beverage cup 10. This application does not specify the method of obtaining the target formula information, as long as the formula of the final beverage to be made can be determined.

[0034] The operating parameters of the aforementioned raw material conveying pump 42 include at least one of the following: the rotational speed and time of the raw material conveying pump 42. This allows raw materials with different physical properties to be transported using corresponding parameters of the raw material conveying pump 42, further ensuring the accuracy of the output and solving the current problem of insufficient extraction of thick juice and excessive extraction of thin juice. This application can use a lower rotational speed for extracting thicker raw materials and a higher rotational speed for extracting thinner raw materials, avoiding the use of a fixed rotational speed for extracting raw materials of different viscousities, thus ensuring the accuracy of juice extraction.

[0035] The aforementioned container 51, raw material outlet pipe 41, and raw material conveying pump 42 are all set up one-to-one, so that the beverage preparation equipment can realize the separate delivery of different raw materials through multiple containers 51 and multiple pipelines. In this way, the flavors of the raw materials will not mix, and multiple combinations of different flavored beverages with different raw materials can be made with high consistency of flavor.

[0036] The beverage preparation equipment described above may also include a temperature control unit 13 and a power supply unit 14. The temperature control unit 13 is used to cool the raw material storage device 5 inside the insulated box 12 to ensure that the raw materials can be stored at low temperatures. The power supply unit 14 provides power to the entire beverage preparation equipment.

[0037] This application utilizes multiple containers 51, each labeled with an identification code, to store different raw materials. A scanning unit 2 scans the codes to obtain the physical parameter information of the raw materials within each container 51. A storage unit stores the corresponding identification codes and physical parameter information. The control unit 1 then determines the operating parameters of the corresponding raw material delivery pump 42 based on this parameter information. This allows for precise control of the raw material delivery pump 42's operating parameters according to the physical parameter information of different raw materials, improving the pump's extraction accuracy for different materials. This results in stable extraction quantities, consistent formula ratios, and consistent flavor, improving the user experience, achieving precise dispensing, and eliminating the need for manual intervention. It is highly intelligent and simplifies user operation. Furthermore, multiple raw material delivery pumps 42 simultaneously supplying raw materials to the beverage cup 10 enables simultaneous juice extraction through multiple pipelines, improving beverage preparation efficiency.

[0038] In some embodiments, such as Figure 7 As shown, the control method further includes steps S201 to S202.

[0039] Step S201: When multiple raw material delivery pumps 42 are controlled to simultaneously supply raw materials to the beverage cup 10, the pipeline information of the corresponding raw material outlet pipe 41 is detected by the pipeline sensor 43 of the delivery device 4; wherein, each raw material outlet pipe 41 is provided with the pipeline sensor 43, and the pipeline information is used to at least characterize whether there is a shortage of material in the corresponding raw material outlet pipe 41.

[0040] Step S202: The control unit 1 controls the operation of the raw material delivery pump 42 based on the pipeline information.

[0041] In this way, the pipeline information of the corresponding raw material outlet pipe 41 can be detected by the pipeline sensor 43 of the conveying device 4, so as to accurately detect whether there is a shortage of material in the raw material outlet pipe 41, and ensure that the raw material conveying pump 42 accurately conveys a certain amount of raw material when it is working, thereby realizing accurate detection of the pipeline information of the raw material outlet pipe 41, and further realizing accurate material discharge and ensuring material discharge stability.

[0042] The aforementioned pipeline sensor 43 may include at least a bubble sensor, which can detect the interference of air in the pipeline on the juice output and achieve accurate detection when there are bubbles in the raw material outflow pipe 41.

[0043] Each of the above-mentioned raw material outflow pipes 41 is equipped with a pipeline sensor 43. That is, the container 51, the pipeline sensor 43, the raw material outflow pipe 41 and the raw material conveying pump 42 are all set in a corresponding manner, so as to realize the simultaneous discharge of multiple pipelines and ensure accurate discharge in multiple dimensions.

[0044] In some embodiments, the beverage preparation device further includes a position sensor 6 communicatively connected to the control unit 1, and the method further includes: After receiving the target recipe information, the control unit 1 obtains detection information on whether the beverage cup 10 is in the correct position as detected by the position sensor 6. When the detection information indicates that the beverage cup 10 is in the "positioned" state, multiple raw material delivery pumps 42 are controlled to simultaneously supply raw materials to the beverage cup 10.

[0045] In this way, the position of the beverage cup 10 can be accurately detected by the position sensor 6. Only after the beverage cup 10 is in position will multiple raw material delivery pumps 42 be controlled to simultaneously supply raw materials to the beverage cup 10, ensuring that the raw materials flowing out of the juice dispensing device 9 can accurately fall into the beverage cup 10, and avoiding the problem of the raw material delivery pumps 42 accidentally discharging raw materials when the beverage cup 10 is not in position.

[0046] The above-mentioned beverage cup 10 being in the "positioned" state can be understood as the beverage cup 10 being in a preset position, such as being located on the tray 7 mentioned below. A limiting groove can be formed on the tray 7, and the beverage cup 10 can be placed in the limiting groove to stably position the beverage cup 10.

[0047] The aforementioned position sensor 6 can be located on the side of the beverage cup 10, and there can be one or more position sensors 6. This application does not make specific limitations on this, as long as it can accurately detect whether the beverage cup 10 is in position.

[0048] In some embodiments, the beverage preparation device further includes a tray 7 and a weighing unit 8 communicatively connected to the control unit 1. The weighing unit 8 is used to weigh the items on the tray 7, and the beverage cup 10 is positioned on the tray 7 in the positioned state. Figure 8 As shown, the control method further includes steps S301 to S303.

[0049] Step S301: When the detection information indicates that the beverage cup 10 is in the positioned state, the initial weight information of the beverage cup 10 is measured by the weighing unit 8.

[0050] Step S302: When multiple raw material delivery pumps 42 simultaneously supply raw materials to the beverage cup 10, the weighing unit 8 weighs the real-time weight information of the beverage cup 10 and the raw materials therein.

[0051] Step S303: When the difference between the real-time weight information and the initial weight information reaches a preset threshold, the delivery pump is stopped by the control unit 1.

[0052] In this way, the initial weight information of the beverage cup 10 can be accurately measured by the weighing unit 8 when the beverage cup 10 is in the correct position, and the real-time weight information of the beverage cup 10 and the raw materials inside it can also be measured in real time after the liquid is drained, so as to accurately weigh the drained raw materials.

[0053] The aforementioned position sensor 6 assists the weighing unit 8 in processing weighing data. When the beverage cup 10 is detected in place, the weighing unit 8 sends the cup weight data, i.e., the initial weight information, to the control unit 1. The control unit 1 records the cup weight and the formula cumulative value to ensure the accuracy of the formula. For example, the target formula information includes the ratio and weight of raw material A, raw material B, and raw material C. The initial weight information represents the cup weight g0, and the target formula information represents the weight of raw material A as g1, the weight of raw material B as g2, and the weight of raw material C as g3. After calculation, the control unit 1 determines the real-time weight information g_total = g0 + g1 + g2 + g3, thereby determining the actual output weight as g1 + g2 + g3. This ensures accurate formula calculation, stable and precise juice output, and thus consistent taste.

[0054] The weighing unit 8 can be connected to the tray 7 via a ball joint. A box structure can be installed outside the weighing unit 8. A waterproof barrier is provided on the top of the box structure. A groove can be formed in the middle part of the tray 7 to stably place the beverage cup 10.

[0055] The weighing unit 8 and the tray 7 are located directly below the juice dispensing device 9. The raw material falls from the juice dispensing device 9 into the beverage cup 10 located on the tray 7. The weighing unit 8 records the accumulated weight each time juice is dispensed and interacts with the control unit 1 to precisely control the dispensing process through the control unit 1.

[0056] The aforementioned preset threshold can correspond to the target formula information. That is, after the target formula information is determined, the actual output weight can be directly determined. When the actual output weight reaches the preset threshold corresponding to the target formula information, the control unit 1 can control the raw material delivery pump 42 to stop working, ensuring accurate dosage and consistent beverage taste.

[0057] The juice output weight m of the single raw material outlet pipe 41 is calculated as m = Q * t * ρ, where Q is the volumetric flow rate, t is the extraction time, and ρ is the raw material density. When multiple raw material outlet pipes 41 are simultaneously discharging juice, the weighing unit 8 can only calculate the total weight, and the specific juice output of each pipe cannot be measured. Using the aforementioned pipe sensor 43 can improve the juice output accuracy of a single pipe without relying on the weighing unit 8, thus ensuring juice output accuracy even when multiple pipes are discharging juice simultaneously.

[0058] In some embodiments, the control unit 1 in step S202 controls the operation of the raw material delivery pump 42 based on the pipeline information, specifically including: When the raw material outflow pipe 41 corresponding to the pipeline information is short of material, the duration of the material shortage in the raw material outflow pipe 41 is determined. The control unit 1 controls the corresponding delivery pump to deliver the corresponding raw materials to the beverage cup 10 based on the material shortage duration.

[0059] In this way, when there is a shortage of material in the raw material outlet pipe 41, the duration of the shortage can be determined, and the feeding time can be compensated based on the duration of the shortage, so as to compensate the beverage cup 10 with the corresponding raw materials, thereby further ensuring the precise control of the dispensing ratio. Especially for scenarios where multiple pipes dispense material at the same time, multiple raw material outlet pipes 41 can be detected and controlled separately, thereby ensuring the accuracy of juice dispensing from each raw material outlet pipe 41.

[0060] In some embodiments, the control method further includes: when the pipeline sensor 43 continuously detects a lack of material in the raw material outflow pipe 41, determining that the raw material in the corresponding container 51 is in a state of shortage, and generating a prompt message to the user indicating that the raw material is in a state of shortage.

[0061] In this way, the material shortage in the raw material outflow pipe 41 can be detected in real time by the pipeline sensor 43. When the raw material in the container 51 is insufficient, the user is promptly notified that the raw material in the container 51 is insufficient, so as to avoid formula imbalance, ensure that the formula can be accurately realized, and ensure consistent taste.

[0062] The above prompts can be delivered in at least one of the following ways: sound, light, and touch screen.

[0063] This application also provides a beverage preparation device. For example... Figures 1 to 5As shown, the beverage preparation equipment includes a control unit 1 and a storage unit, a barcode scanning unit 2, a conveying device 4, and a raw material storage device 5, all communicatively connected to the control unit 1. The raw material storage device 5 includes multiple containers 51 for storing different raw materials. The conveying device 4 includes multiple raw material outlet pipes 41 and raw material conveying pumps 42 corresponding to the multiple containers 51. The raw material conveying pumps 42 supply raw materials to the beverage cup 10 through the corresponding raw material outlet pipes 41. The barcode scanning unit 2 is used to identify the identification codes on each container 51 to obtain the physical parameter information of the raw materials in the corresponding container 51. The storage unit stores the corresponding identification codes and physical parameter information in association. The control unit 1 is used to determine the operating parameters of the corresponding raw material conveying pump 42 based on the parameter information. The control unit 1 is used to obtain the operation instructions for the target formula information selected from multiple formula information. The storage unit stores multiple formula information corresponding to different raw material ratios. The control unit 1 is used to control the multiple raw material conveying pumps 42 to simultaneously supply raw materials to the beverage cup 10 based on the target formula information and the operating parameters of the corresponding raw material conveying pump 42.

[0064] This application utilizes multiple containers 51, each labeled with an identification code, to store different raw materials. A scanning unit 2 scans the codes to obtain the physical parameter information of the raw materials within each container 51. A storage unit stores the corresponding identification codes and physical parameter information. The control unit 1 then determines the operating parameters of the corresponding raw material delivery pump 42 based on this parameter information. This allows for precise control of the raw material delivery pump 42's operating parameters according to the physical parameter information of different raw materials, improving the pump's extraction accuracy for different materials. This results in stable extraction quantities, consistent formula ratios, and consistent flavor, improving the user experience, achieving precise dispensing, and eliminating the need for manual intervention. It is highly intelligent and simplifies user operation. Furthermore, multiple raw material delivery pumps 42 simultaneously supplying raw materials to the beverage cup 10 enables simultaneous juice extraction through multiple pipelines, improving beverage preparation efficiency.

[0065] In some embodiments, such as Figures 9 to 11 As shown, the beverage preparation equipment also includes a juice dispensing device 9 disposed above the beverage cup 10. The juice dispensing device 9 includes a liquid dispensing valve body 91 connected to the raw material outflow pipe 41. The liquid dispensing valve body 91 has multiple flexible opening and closing nozzles 92 for dispensing different raw materials respectively. When raw materials flow to the liquid dispensing valve body 91, the flexible opening and closing nozzles 92 switch from a closed state to an open state under pressure. That is, the aforementioned flexible opening and closing nozzles 92 can open under pressure and close when the pressure is removed.

[0066] In this way, multiple outlets can be dispensed simultaneously through the dispensing valve body 91, avoiding the problem of mixing different raw materials. Furthermore, the structural design of the flexible opening and closing nozzle 92 can solve the problem of dripping from the pipeline after the raw material delivery pump 42 stops working, further ensuring the accurate realization of the formula and avoiding the problem of mixing different raw materials. The aforementioned liquid outlet valve body 91 may have a sealing ring 99, which is sleeved on the outside of the discharge pipe 93 to ensure the discharge sealing of the liquid outlet valve body 91.

[0067] The aforementioned discharge valve body may be entirely made of silicone and is assembled with the discharge pipe 93 for stable discharge. The number of flexible opening and closing nozzles 92 matches the number of discharge pipes 93 and containers 51. The axes of the multiple flexible opening and closing nozzles 92 are parallel and approximately located in the same plane. The discharge valve body 91 may have an annular abutment surface, with a sealing ring 99 located above the abutment surface. The discharge pipe 93 abuts against the abutment surface to ensure tight contact with the discharge valve body 91.

[0068] The aforementioned multiple flexible opening and closing mouthpieces 92 can be arranged in an array.

[0069] In some embodiments, such as Figures 9 to 11 As shown, the juice dispensing device 9 also includes a discharge pipe 93 and a mounting bracket 94. The discharge pipe 93 is provided in a one-to-one correspondence with the elastic opening and closing nozzle 92, and the discharge end of the discharge pipe 93 abuts against the inner wall surface of the liquid dispensing valve body 91. The mounting bracket 94 includes a first bracket 95 and a second bracket 96 magnetically connected. The first bracket 95 is equipped with the discharge pipe 93, and the second bracket 96 is equipped with the liquid dispensing valve body 91.

[0070] Thus, the first frame 95 and the second frame 96 can be magnetically connected to facilitate the disassembly of the liquid outlet valve body 91, thereby facilitating daily cleaning and maintenance of the liquid outlet valve body 91 (such as clogging of the elastic opening and closing nozzle 92).

[0071] The first frame 95 may be provided with a first magnetic component 97, and the second frame 96 may be provided with a second magnetic component 98. Both the first magnetic component 97 and the second magnetic component 98 may be constructed as plates to facilitate the stable installation of the discharge pipe 93 and the liquid discharge valve body 91.

[0072] The second frame 96 is fixedly connected to the liquid outlet valve body 91 to ensure the stability of the connection between the two.

[0073] In some embodiments, such as Figure 5As shown, the beverage preparation equipment also includes a cleaning device 3, and the conveying device 4 includes multiple raw material inflow pipes 44. The raw material inflow pipes 44 are connected to each of the containers 51 through the raw material conveying pump 42 and the raw material outflow pipe 41. The cleaning device 3 includes a cleaning pump 31 and multiple cleaning pipes 32 connected to the cleaning pump 31. The multiple cleaning pipes 32 are connected to each of the raw material inflow pipes 44 in a one-to-one correspondence. The cleaning pump 31 is used to open under the control of the control unit 1 to provide cleaning liquid to each of the raw material inflow pipes 44 and the raw material outflow pipes 41.

[0074] Thus, the cleaning device 3 can achieve simultaneous cleaning of each of the raw material inflow pipes 44 and raw material outflow pipes 41. That is, one cleaning device 3 can clean all the raw material inflow pipes 44 and raw material outflow pipes 41, realizing the daily cleaning and maintenance of the pipelines and ensuring the food safety of the raw materials.

[0075] The beverage preparation equipment also includes a cleaning device 3, and the conveying device 4 includes multiple raw material inflow pipes 44. The raw material inflow pipes 44 are connected to each of the containers 51 through the raw material conveying pump 42 and the raw material outflow pipe 41. The cleaning device 3 includes a cleaning pump 31 and multiple cleaning pipes 32 connected to the cleaning pump 31. The multiple cleaning pipes 32 are connected to each of the raw material inflow pipes 44 in a one-to-one correspondence. The cleaning pump 31 is used to open under the control of the control unit 1 to provide cleaning liquid to each of the raw material inflow pipes 44 and the raw material outflow pipes 41.

[0076] The aforementioned conveying device 4 may further include a first check valve 45, and a second check valve 33 may be provided on the cleaning pipeline 32. The first check valve 45 and the second check valve 33 are respectively used to cut off backflow in the pipeline. When the raw material conveying pump 42 receives the command from the control unit 1 to operate, the first check valve 45 opens and the second check valve 33 closes. The raw material flows through the first check valve 45 and the raw material conveying pump 42 to the juice dispensing device 9. At this time, the closing force F1 of the second check valve 33 is greater than the sum of the closing force F2 of the first check valve 45 and the working negative pressure F3 of the raw material conveying pump 42, so that the second check valve 33 can be stably closed and will not accidentally draw water when the raw material conveying pump 42 is drawing juice. This achieves the orderly closing of the first check valve 45 and the second check valve 33 to prevent the raw material from mixing with the cleaning liquid.

[0077] When the cleaning pump 31 is working, the pressure F4 generated is greater than the closing force F1 of the second check valve 33. At this time, the second check valve 33 is open and the first check valve 45 is closed. The cleaning liquid provided by the cleaning pump 31 flows out through the cleaning pump 31, the second check valve 33, and the juice outlet device 9, realizing that multiple raw material inflow pipes 44 are connected in parallel to the cleaning pipeline 32. Only one cleaning pump 31 is needed to complete the delivery of cleaning liquid and clean all the raw material delivery pumps 42 at the same time.

[0078] In some embodiments, each of the raw material outlet pipes 41 is provided with a pipeline sensor 43, and the pipeline information is used at least to characterize whether there is a shortage of material in the corresponding raw material outlet pipe 41. The pipeline sensor 43 is used to detect the pipeline information of the corresponding raw material outlet pipe 41 when multiple raw material delivery pumps 42 are simultaneously supplying raw materials to the beverage cup 10. The control unit 1 is also used to control the operation of the raw material delivery pumps 42 based on the pipeline information.

[0079] In some embodiments, the beverage preparation equipment further includes a position sensor 6 communicatively connected to the control unit 1. The control unit 1 is further configured to, upon receiving the target recipe information, acquire detection information indicating whether the beverage cup 10 is in the correct position as detected by the position sensor 6; and, if the detection information indicates that the beverage cup 10 is in the correct position, control a plurality of the raw material delivery pumps 42 to simultaneously supply raw materials to the beverage cup 10.

[0080] In some embodiments, the beverage preparation equipment further includes a tray 7 and a weighing unit 8 communicatively connected to the control unit 1. The weighing unit 8 is used to weigh the items on the tray 7, and the beverage cup 10 is located on the tray 7 in the positioned state. The weighing unit 8 is used to: weigh the initial weight information corresponding to the beverage cup 10 when the detection information indicates that the beverage cup 10 is in the positioned state; and weigh the real-time weight information corresponding to the beverage cup 10 and the raw materials therein when multiple raw material delivery pumps 42 simultaneously supply raw materials to the beverage cup 10. The control unit 1 is also used to control the delivery pump to stop working when the difference between the real-time weight information and the initial weight information reaches a preset threshold.

[0081] In some embodiments, the control unit 1 is further configured to determine the duration of material shortage in the raw material outlet pipe 41 when the pipeline information characterizes a material shortage; and control the corresponding delivery pump to deliver the corresponding raw material to the beverage cup 10 based on the material shortage duration.

[0082] In some embodiments, the control unit 1 is further configured to determine that the raw material in the corresponding container 51 is in a state of shortage when the pipeline sensor 43 continuously detects that the raw material outflow pipe 41 is short of material, and generate a prompt message to the user that the raw material is in a state of shortage.

[0083] The following explains how to use the beverage preparation equipment: First, the control unit 1 receives the operation command for making the beverage from the smart terminal 11. Based on the target recipe information and the operating parameters of the raw material delivery pump 42 determined by the parameter information, the control unit 1 controls multiple raw material delivery pumps 42 to simultaneously supply raw materials to the beverage cup 10. At this time, the position sensor 6 will detect whether the beverage cup 10 is placed in the designated position on the tray 7. If the beverage cup 10 is in the designated position, the raw material delivery pump 42 will start to dispense juice (the operating parameters of the raw material delivery pump 42 are different for different raw materials. Generally speaking, the higher the density and viscosity of the raw material, the lower the speed of the raw material delivery pump 42). If the beverage cup 10 is not in the designated position, the information is fed back to the control unit 1. The control unit 1 displays the missing cup information to the user through the touch screen. After the user resolves the problem, the beverage making continues.

[0084] After the raw material delivery pump 42 starts dispensing juice, the weighing unit 8 first measures the weight of the cup g0 and stores the cup weight information in the control unit 1 for subsequent juice weight calculation. For example, a juice formula includes raw material A weighing g1, raw material B weighing g2, raw material C weighing g3, ..., raw material N weighing gn, and the corresponding formula weight is g1+g2+g3+...+gn. The target weight g_total = g0+g1+g2+g3+...+gn. During the dispensing process, the pipeline sensor 43 detects in real time whether each raw material outlet pipe 41 is short of material. If there are air bubbles or blockages causing a material shortage, the pipeline sensor 43 will collect the duration of the material shortage and feed it back to the control unit 1. The control unit 1 sends an operation command to the corresponding raw material delivery pump 42 to increase the corresponding material shortage duration to compensate for the missing weight. When the actual juice weight reaches the preset threshold corresponding to the target recipe information, it means that the production requirements have been met. When the pipeline sensor 43 continuously detects a lack of material, it means that the raw materials in the container 51 have been used up. The information on the completion of beverage production and the lack of material will be displayed on the touch screen for user management.

[0085] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its scope and spirit, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
