[0038] Figure 1 It is a schematic structural diagram of a beverage production device provided by this application;

[0039] Figure 2 It is a flowchart of a method for outputting a liquid material provided by this application. Specific embodiments

[0040] Next, the embodiments in this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by this application.

[0041] To make the above objects, features, and advantages of this application more obvious and understandable, the following further detailed description of this application will be made in conjunction with the drawings and specific embodiments.

[0042] As described in the background art section, after the liquid output of the existing beverage production device ends, due to factors such as the pressure and gravity of the liquid output pipeline, there will be a phenomenon of liquid dripping, which in turn leads to the problem of inaccurate liquid output. Inaccurate liquid output will not only affect the taste of the beverage prepared this time, but also cause inaccurate liquid output in the next time, and then affect the taste of the beverage prepared next time. Especially for some key materials with high concentration and strong taste, such as sugar solution, if the liquid output is inaccurate, it will seriously affect the taste of the beverage and thus affect the customer experience.

[0043] Based on this, this application provides a method for outputting a liquid material, and this output method is used to control a liquid output device to output a liquid material, such as Figure 1As shown in the figure, the liquid output device includes: a liquid storage tank 100, a liquid outlet 200, a liquid pump 400, and a controller 500. The liquid storage tank 100 is used to store liquid materials, and the liquid storage tank 100 is communicated with the liquid outlet 200 through a liquid delivery pipeline 300, so that the liquid materials in the liquid storage tank 100 can be transmitted to the liquid outlet 200 and output through the liquid outlet 200. The liquid pump 400 is arranged in the liquid storage tank 100 and is used to output the liquid materials stored in the liquid storage tank 100 through the liquid outlet 200 under the control of the controller 500. As Figure 2 shown Figure 2 is a flowchart of an output method for liquid materials provided by this application. The output method includes:

[0044] S1: The controller 500 controls the motor in the liquid pump 400 to perform a first rotation operation in a first direction to output liquid materials through the liquid outlet 200, that is, to drive the materials in the liquid storage tank 100 to the liquid delivery port 200 and output them through the liquid outlet 200. That is to say, the first rotation operation is a liquid output operation.

[0045] S2: When a condition for triggering the stop of liquid material output is met, the controller 500 controls the motor in the liquid pump 400 to perform a second rotation operation in a second direction, which is opposite to the first direction, to draw back the liquid materials in the liquid delivery pipeline 300, and then drive the liquid materials in the liquid delivery pipeline 300 in the direction of the liquid storage tank 100, so that the liquid materials in the liquid delivery pipeline 300 move towards the liquid storage tank 100. In practical applications, the condition for stopping the output of liquid materials can be that the weight of the output liquid reaches a preset weight (for example, an electronic scale can be set under the cup for receiving liquid materials to weigh, and the weighing result can be fed back to the controller 500 in real time by the electronic scale), or the rotation amount of the motor in the liquid pump 400 during the first rotation operation reaches a preset rotation amount, or the rotation time of the motor in the liquid pump 400 during the first rotation operation reaches a preset time, or other preset triggering conditions.

[0046] As described above, the output method uses the controller 500 to control the liquid pump 400 to perform a first rotation operation to output liquid materials. After the liquid discharging operation is completed, the controller 500 is used to control the liquid pump 400 to perform a second rotation operation in the reverse direction. Thus, after the liquid discharging operation is completed, the liquid materials in the liquid delivery pipeline 300 can be back-sucked, so as to drive the liquid materials in the liquid delivery pipeline 300 towards the direction of the liquid storage tank 100, thereby weakening the ability of the liquid materials in the liquid delivery pipeline 300 to drip from the liquid outlet 200, effectively suppressing the problem that the liquid materials in the liquid delivery pipeline 300 drip after the liquid discharging operation, and further effectively solving the problem of inaccurate liquid discharging of the liquid materials, which helps to ensure the taste of the beverage.

[0047] For step S2, in an embodiment of the present application, using the controller to control the motor in the liquid pump to perform a second rotation operation in a second direction includes:

[0048] Obtain a first rotation amount, where the first rotation amount is the required rotation amount when the motor in the liquid pump 400 performs the second rotation operation.

[0049] Use the controller 500 to control the motor in the liquid pump 400 to perform the second rotation operation based on the first rotation amount, so as to back-suck the liquid materials in the liquid delivery pipeline 300.

[0050] As known from the above, the purpose of using the controller 500 to control the liquid pump 400 to perform the second rotation operation is to drive the liquid materials in the liquid delivery pipeline 300 towards the direction of the liquid storage tank 100 after the first rotation operation is completed, so that the liquid materials in the liquid delivery pipeline 300 move towards the liquid storage tank 100 or have a tendency to move towards the liquid storage tank 100, rather than simply referring to back-sucking all the liquid materials in the liquid delivery pipeline 300 into the liquid storage tank 100. In view of this, it is necessary to control the rotation amount when the liquid pump 400 performs the second rotation operation. The rotation amount of the second rotation operation cannot be too large, otherwise more time and electric energy will be wasted, nor can it be too small, otherwise it will not be sufficient to drive the liquid materials in the liquid delivery pipeline 300 towards the direction of the liquid storage tank 100. Therefore, it is necessary to reasonably determine the required rotation amount of the second rotation operation, that is, the first rotation amount, to control the rotation amount when the liquid pump 400 performs the second rotation operation, so that the liquid materials in the liquid delivery pipeline 300 will neither drip from the liquid outlet 200 nor be back-sucked too far.

[0051] Based on the above embodiment, in an embodiment of the present application, obtaining the first rotation amount includes:

[0052] Determine a rotation coefficient. Among them, different rotation coefficients correspond to different liquid materials when back-sucking.

[0053] Based on the product of the rotation coefficient and the preset rotation amount, determine the first rotation amount, that is, the first rotation amount is equal to the product of the rotation coefficient and the preset rotation amount. Wherein, the preset rotation amount is a preset default rotation amount, and this preset rotation amount is related to parameters such as the structure and performance of the liquid pump itself.

[0054] It should be noted that due to the nature of different liquid materials, the required back-pumping rotation amount generally differs from the preset rotation amount. Therefore, it is necessary to determine the rotation coefficient corresponding to the liquid material in the infusion pipeline 300, and then obtain the required rotation amount, that is, the first rotation amount, when back-pumping the liquid material in the infusion pipeline 300 based on the product of the rotation coefficient and the preset rotation amount, so as to back-pump the liquid material in the infusion pipeline 300.

[0055] Based on the above embodiments, in an embodiment of the present application, determining the rotation coefficient includes:

[0056] Obtain the viscosity value of the liquid material.

[0057] Based on the viscosity value and the first correspondence, determine the rotation coefficient when the motor in the liquid pump 400 performs the second rotation operation.

[0058] The first correspondence is the correspondence between the viscosity value of the liquid material pre-configured and the rotation coefficient. Among them, the viscosity value of the liquid material is inversely proportional to the rotation coefficient when it performs the second rotation operation, that is, the greater the viscosity value of the liquid material, the smaller the rotation coefficient when the liquid pump performs the second rotation operation, and the smaller the first rotation amount. Conversely, the smaller the viscosity value of the liquid material, the greater the rotation coefficient when the liquid pump performs the second rotation operation, and the greater the first rotation amount. Among them, the material viscosity is one of the important factors affecting the back-pumping rotation amount when back-pumping liquid materials. For liquids with low viscosity and strong fluidity, it is easier to drip, so a larger rotation coefficient needs to be set; conversely, for liquids with high viscosity and poor fluidity, it is relatively less likely to drip, and a smaller rotation coefficient can be set. By setting like this, the back-pumping operation can be implemented more accurately, that is, it meets the requirement of preventing dripping and can avoid excessive back-pumping, thus consuming more electric energy and time.

[0059] It should be noted that the viscosity values of different liquid materials are different. Therefore, each different liquid material has a corresponding relationship between the viscosity value and the rotation coefficient, which is obtained in advance and pre-configured in the controller 500 for standby. Specifically, it can be stored in the built-in memory of the controller 500 or in a memory associated with the controller. The method for obtaining the corresponding relationship between the viscosity value and the rotation coefficient of the liquid material includes: after the liquid pump 400 performs a first rotation operation, controlling the liquid pump to perform a second rotation operation. Through multiple experiments, when a certain viscosity value is obtained, the amount of back-pull rotation that can control the weight of the material dripping from the liquid outlet 200 within the allowable range is obtained. Then, when different viscosity values are obtained, the amount of back-pull rotation that can control the weight of the material dripping from the liquid outlet 200 within the allowable range is obtained. Among them, the rotation coefficient is the ratio between the default rotation amount and the actual back-pull rotation amount, and thus the corresponding relationship between the rotation coefficient and the viscosity value is obtained.

[0060] Based on the above embodiments, in an embodiment of the present application, obtaining the viscosity value of the liquid material includes:

[0061] Obtaining the current temperature of the liquid material in the liquid storage tank 100. Specifically, the current temperature of the liquid material in the liquid storage tank 100 can be obtained through a temperature sensor or the like.

[0062] Based on the current temperature of the liquid material in the liquid storage tank 100 and the second corresponding relationship, determining the viscosity value of the current liquid material in the liquid storage tank 100.

[0063] The second corresponding relationship is the pre-configured corresponding relationship between the material temperature and the viscosity value. Among them, each different liquid material has a corresponding pre-configured corresponding relationship between the material temperature and the viscosity value.

[0064] Since the viscosity of a liquid is related to its temperature, the higher the temperature, the lower the viscosity. Therefore, when determining the viscosity value of the liquid material in the liquid delivery pipeline 300, the current temperature of the liquid material also needs to be considered. Thus, this liquid outlet method determines the viscosity value of the current liquid material in the liquid storage tank 100 based on the current temperature of the liquid material in the liquid storage tank 100 and the second corresponding relationship, thereby further optimizing the determination of the viscosity value and the rotation coefficient and improving the accuracy of the back-pull operation.

[0065] It should be noted that the corresponding relationship between the material temperature and the viscosity value of the liquid material, i.e., the second corresponding relationship, is obtained through experiments and stored in the controller 500 in advance. When the corresponding relationship curve is obtained as needed, the viscosity value corresponding to the current material temperature can be obtained, and then the rotation coefficient corresponding to the current material temperature can be obtained, so as to achieve precise control of the first rotation amount, i.e., the back-drawing rotation amount, and effectively suppress the problem of the material dripping from the liquid outlet 200. Taking mango jam as an example, obtaining its viscosity curve includes: in the laboratory, putting the mango jam in a test cup, and in the temperature range from T1 to T4, putting the test cup containing the mango jam in a constant temperature water bath instrument and equipment, and setting the usage scenario temperatures as T1, T2, T3, and T4 (T1 < T2 < T3 < T4) respectively. Then, using a high-precision viscometer, the viscosity values Y1, Y2, Y3, and Y4 at temperatures T1, T2, T3, and T4 are measured respectively. Y1, Y2, Y3, and Y4 show a linear relationship, specifically, the lower the temperature, the higher the viscosity value, and vice versa, the lower the viscosity value. By using the known temperature and viscosity values, and the expression Y = -aT + b, the values of a and b are obtained, so as to obtain the viscosity curve of the mango jam, and then in subsequent practical applications, the viscosity value of the mango jam at different temperatures can be obtained.

[0066] It should be noted that different materials have different requirements for storage temperature, which results in different temperatures of the liquid storage tanks 100 storing different liquid materials. However, before the liquid material is placed in the corresponding liquid storage tank 100, its temperature cannot be guaranteed to be the same as that of the corresponding liquid storage tank 100. If the temperature of the material before being placed in the corresponding liquid storage tank 100 is different from that of the liquid storage tank 100, it needs to be cooled or heated for a period of time before it can be the same as the temperature of the corresponding liquid storage tank 100. Then, within this period of time, the temperature of the material is changing, and thus its viscosity value is also changing. Consequently, the first rotation amount when the liquid pump 400 performs the second rotation operation is also changing. Then, within this period of time, it is necessary to detect the temperature of the liquid material to adjust the first rotation amount when the liquid pump 400 performs the second rotation operation in real time, so as to avoid the situation of the material dripping from the liquid outlet 200.

[0067] For this output method, in an embodiment of the present application, the liquid outlet method further includes:

[0068] S3: Record the first rotation amount.

[0069] S4: After the end of the second rotation operation, if the motor in the liquid pump 400 performs a second first rotation operation in the first direction, that is, when the current beverage production process ends and the next cup of beverage needs to be produced and secondary liquid discharge is to be performed, the rotation amount during the second first rotation operation of the motor in the liquid pump 400 is compensated based on the first rotation amount. That is to say, during the second first rotation operation, the rotation amount is the sum of the first rotation amount and the rotation amount required this time.

[0070] Since the liquid pump 400 has performed the second rotation operation before, driving the liquid material in the infusion pipeline 300 to move towards the liquid pump 400, it is equivalent that there is no liquid material at the liquid outlet 200. Instead, due to the effect of the second rotation operation, the liquid in the infusion pipeline 300 has retreated a certain distance towards the liquid pump 400, that is, a certain distance at one end of the infusion pipeline 300 near the liquid outlet 200 is emptied. Then, when performing the next first rotation operation, it is necessary to compensate for the previous second rotation operation, that is, compensate for the above distance, and then discharge the liquid according to the liquid discharge amount required for the second cup of beverage. If the above distance is not compensated and the liquid is directly discharged according to the liquid discharge amount of the second cup of beverage, the infusion pipeline will first move towards the liquid outlet 200 by the above distance and then can be output. Then, part of the liquid will be used to fill the empty space of the above distance and will not be actually output, resulting in inaccurate liquid discharge.

[0071] For example, when making the second cup of beverage, first, the required liquid discharge amount for the second first rotation operation of the liquid pump 400 is obtained according to the formula of the current beverage, that is, the liquid discharge amount of the secondary liquid discharge is obtained.

[0072] Based on the liquid discharge amount, a third rotation amount is obtained, and this third rotation amount is the rotation amount without considering the second rotation operation performed by the liquid pump 400 before.

[0073] Based on the sum value of the first rotation amount and the third rotation amount, the rotation amount required for performing the first rotation operation to produce the current beverage is obtained. For example, the number of reverse rotation circles when the liquid pump 400 performs the second rotation is 50 circles, that is, the first rotation amount is 50 circles, and the number of positive rotation circles obtained based on the secondary liquid discharge amount is 200 circles, that is, the third rotation amount is 200 circles. Then, the number of positive rotation circles when the liquid pump 400 performs the first rotation when making the second cup of beverage is 250 circles.

[0074] Correspondingly, the present application also provides a beverage production device, as Figure 1 shown Figure 1Schematic structural diagram of a beverage making device provided for this application. The beverage making device includes a liquid output device. The liquid output device 1 includes: a liquid storage tank 100, a liquid outlet 200, a liquid pump 400, and a controller 500. Among them, the liquid storage tank 100 is used to store liquid materials, that is, the liquid storage tank 100 is the liquid storage bin of the beverage making device and is used to hold the materials required for preparing beverages; the liquid outlet 200 is connected to the liquid storage tank 100 through an infusion pipeline 300, so that the materials in the liquid storage tank 100 can be transmitted to the liquid outlet 200 and output through the liquid outlet 200; the liquid pump 400 is used to transmit the materials in the liquid storage tank 100 through the infusion pipeline 300 to the infusion port 200, and then output through the liquid outlet 200 for making beverages. It should be noted that the infusion pipeline 300 needs to be immersed below the liquid level of the liquid materials in the liquid storage tank 100 and is connected to the liquid outlet 200 via the liquid pump 400.

[0075] The controller 500 is used to control the motor in the liquid pump 400 to perform a first rotation operation in a first direction to output liquid materials through the liquid outlet 200, that is, to drive the materials in the liquid storage tank 100 to the infusion port 200 and output through the liquid outlet 200. That is to say, the first rotation operation is an out-liquid operation.

[0076] And the controller 500 is further used to control the motor in the liquid pump 400 to perform a second rotation operation in a second direction when a condition for triggering the stop of outputting liquid materials is met. The second direction is opposite to the first direction to suck back the liquid materials in the infusion pipeline 300, and then drive the liquid materials in the infusion pipeline 300 in the direction of the liquid storage tank 100, so that the liquid materials in the infusion pipeline 300 move towards the liquid storage tank 100.

[0077] As can be seen from the above, when the beverage making device discharges liquid, the controller 500 controls the liquid pump 400 to perform a first rotation operation to output the materials in the liquid storage tank 100 through the liquid outlet 200 for the out-liquid operation. After the out-liquid operation is completed, the controller 500 controls the liquid pump 400 to perform a second rotation operation in the reverse direction to suck back the materials in the infusion pipeline 300, so that the liquid materials in the infusion pipeline 300 are driven in the direction of the liquid storage tank 100, thereby weakening the ability of the liquid materials in the infusion pipeline 300 to drip from the liquid outlet 200, effectively suppressing the problem that the liquid materials in the infusion pipeline 300 drip after the out-liquid operation is completed, and effectively solving the problem of inaccurate liquid discharge of liquid materials, which helps to ensure the taste of beverages.

[0078] It should be noted that when the liquid pump 400 outputs or pumps back the liquid, it is caused by the rotation of the structures such as the blades driven by the motor of the liquid pump, and the motor will rotate under the control of the controller. In practical applications, the above liquid pump can be a peristaltic pump, and the motor inside it can be a stepper motor.

[0079] It should also be noted that the first rotation operation of the liquid pump 400 is usually the forward rotation of the liquid pump 400, and the second rotation operation of the liquid pump 400 is usually the reverse rotation of the liquid pump 400, but this application does not limit this, and it depends on the specific situation.

[0080] For the controller 500, in an embodiment of the present application, the controller 500 is further configured to record the first rotation amount; and after the second rotation operation ends, if the motor in the liquid pump 400 performs a secondary first rotation operation along the first direction, compensate the rotation amount during the secondary first rotation operation of the motor in the liquid pump 400 based on the first rotation amount.

[0081] Since the liquid pump 400 has performed the second rotation operation before, driving the liquid material in the infusion pipeline 300 to move towards the liquid pump 400, then during the next first rotation operation, it is necessary to compensate for the previous second rotation operation to ensure the accuracy of the next liquid output.

[0082] It should be noted that since a beverage is usually prepared from multiple liquid materials, and different beverages require different materials. Therefore, in an embodiment of the present application, the liquid storage tank 100 includes a plurality of sub-liquid storage tanks 101, and the plurality of sub-liquid storage tanks 101 are respectively used to store different liquid materials, that is, each sub-liquid storage tank 101 contains one liquid material to meet the material requirements for beverage production. Since the above-known liquid pump 400 is used to drive the liquid material in the liquid storage tank 100 under the control of the controller 500, accordingly, when there are a plurality of sub-liquid storage tanks 101, the liquid pump 400 also includes a plurality of sub-liquid pumps 401, and the plurality of sub-liquid pumps 401 correspond to the plurality of sub-liquid storage tanks 101 one by one, and are respectively used to drive the materials in the corresponding sub-liquid storage tanks 101 to be output through the liquid outlet 200 to achieve the preparation of beverages.

[0083] Based on the above embodiments, in an embodiment of the present application, the beverage making device further includes: an input unit 600, which is configured to determine the material recipe of the beverage to be made currently according to the user's input. The material recipe includes the materials required for preparing the beverage and the proportion of each material. Specifically, the input unit 600 can access the material recipes of various beverages stored in the controller. When making a beverage, the staff can input the name of the beverage to be prepared, query the material recipe of the beverage, and determine the material recipe of the beverage to be prepared currently. In practical applications, the above input unit can also be a barcode scanner. After the user places an order, a two-dimensional code corresponding to the beverage in this order will be generated (the two-dimensional code can be printed on a piece of paper by a printer). The barcode scanner can be connected or integrated with the beverage making device. After the barcode scanner scans the two-dimensional code, it will identify the beverage in this order, and then identify the recipe of the beverage. Next, the production of the beverage will start. The present application does not limit the type of the input unit, which depends on the specific situation.

[0084] After determining the material recipe of the beverage to be prepared currently, the controller 500 controls at least one of the plurality of sub-liquid pumps 401 to perform a first rotation operation based on the material recipe of the beverage to be prepared currently, and controls the at least one sub-liquid pump 401 to perform a second rotation. That is to say, after determining the material recipe of the beverage to be prepared currently, the controller 500 controls at least one of the plurality of sub-liquid pumps 401 to perform a first rotation operation based on the material recipe of the beverage to be prepared currently, so that the material of the required weight is output through the liquid outlet. After outputting the material of the required weight, the controller 500 also controls the above at least one sub-liquid pump 401 to perform a second rotation to draw back the material in the infusion pipeline.

[0085] As can be seen from the above, the beverage making device only requires the staff to confirm the material recipe of the beverage to be prepared, and the subsequent preparation process is automatically completed by the beverage making device, which can greatly improve the beverage making efficiency and save labor costs. Therefore, while ensuring the taste of the beverage, the beverage making device also ensures the beverage making efficiency and reduces the labor cost.

[0086] In summary, the present application provides a method for outputting liquid materials and a beverage making device. The output method includes, when the liquid output device outputs liquid materials, using a controller to control a liquid pump to perform a first rotation operation to output the liquid materials, and after the liquid discharging operation is completed, using the controller to control the liquid pump to perform a second rotation operation in the reverse direction. Thus, after the liquid discharging operation is completed, the output method can perform a back-pumping operation on the materials in the liquid delivery pipeline to drive the liquid materials in the liquid delivery pipeline towards the direction of the liquid storage tank, thereby weakening the ability of the liquid materials in the liquid delivery pipeline to drip from the liquid outlet, effectively suppressing the problem that the liquid materials in the liquid delivery pipeline drip after the liquid discharging operation is completed, and further effectively solving the problem of inaccurate liquid discharging of the liquid materials, which helps to ensure the taste of the beverage.
