Technical Field

[0001] This application belongs to the field of data processing technology, and in particular relates to a control method, device, electronic scale and storage medium for use in electronic scales. Background Technology

[0002] With the continuous development of electronic technology, more and more products are moving towards electronicization. For example, in the field of weighing, electronic scales have gradually replaced traditional scales in daily life and work due to their greater convenience, accuracy and aesthetics.

However, as users pay more and more attention to healthy eating, when weighing coffee beans, users often need to determine not only their weight but also their caffeine content.

Detailed Implementation

[0021] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0022] It should be understood that, when used in this application specification and the appended claims, the term "comprising" indicates the presence of the described features, integrals, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or a collection thereof.

[0023] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] The control method for electronic scales provided in this application embodiment can be applied to electronic scales. For example, Figure 1 A schematic diagram of the structure of an electronic scale according to an embodiment of this application is shown. See also Figure 1 As shown, the electronic scale may include the following components: a weighing component 11 and a display screen 12. The weighing component 11 can be used to obtain the weight of coffee beans to be measured, or the weight of other objects to be weighed. The display screen 12 can be used to display the weight of the object to be weighed, for example, the weight of the coffee beans to be measured.

[0025] In this embodiment, the electronic scale may further include a processor 13, which can acquire coffee bean information and process the coffee bean information to determine the caffeine information corresponding to the weight of the coffee beans. In the case where the coffee bean information includes the weight of the coffee beans, the coffee bean information may be acquired by the weighing component 11 and sent to the processor 13.

[0026] In this embodiment, the electronic scale also includes a timing module, which can calculate the brewing time corresponding to the coffee brewing process.

[0027] In some possible implementations, the electronic scale may also include a voice recognition module, which can acquire the user's voice signal. The processor 13 can perform voice recognition on the voice signal, thereby acquiring some information from the coffee bean information, such as the type of coffee bean, the roasting method of the coffee bean, etc., and can also acquire brewing process information through the voice signal.

[0028] In some possible implementations, the electronic scale may also include a touch module. The touch module can be configured with corresponding touch controls for different items. For example, users can select the brewing method or coffee bean type through the touch module. Users can also input coffee bean information and brewing process information into the electronic device through the touch module.

[0029] In some possible implementations, the aforementioned electronic scale may also include a communication module, such as a Bluetooth communication module, a mobile communication module, or a WiFi communication module. The electronic device can communicate with the user's smart terminal through the communication module, such as with the user's mobile phone or tablet computer, thereby obtaining user information related to the user through the smart terminal, as well as information such as brewing process and / or coffee bean information entered by the user on the smart terminal, which improves the efficiency and diversity of information acquisition methods.

[0030] Please see Figure 2 , Figure 2 A schematic diagram illustrating an implementation of a control method for an electronic scale according to an embodiment of this application is shown. This control method is applied to the aforementioned electronic scale. Specifically, the method includes the following steps: In S201, in response to a measurement command, information about the coffee beans to be measured is acquired; the coffee bean information includes the weight of the coffee beans to be measured.

[0031] In this embodiment, the electronic scale can generate corresponding measurement commands when it needs to measure an object to be weighed. For example, the weighing component of the electronic scale can acquire the weight value of the object placed on it, and if the weight value is greater than a preset pressure threshold, a corresponding measurement command can be generated; or, for example, the electronic scale can include a voice recognition module, allowing the user to trigger the measurement process and generate corresponding measurement commands through voice keywords.

[0032] In some possible implementations, the electronic scale can receive the user's selection instruction and determine whether the object to be measured is coffee beans. If the object to be measured is coffee beans, the process of S201 to S203 can be executed. In addition to displaying the weight of the coffee beans to be measured on the electronic scale, the corresponding caffeine information can also be determined based on the weight of the coffee beans, and the weight of the coffee beans and the caffeine information can be displayed on the screen.

[0033] In some possible implementations, the electronic scale can also receive touch operations from the user on the touchpad. The touch operations can be used to indicate that the object to be weighed is coffee beans and trigger the weighing process. The electronic scale can respond to the touch operations and perform operations S201 to S203.

[0034] In this embodiment, the user can place the coffee beans to be weighed on the weighing component of the electronic scale. The weighing component includes a gravity sensor, which can obtain the weight of the coffee beans placed on it and obtain the coffee bean information based on the weight of the coffee beans.

[0035] In some possible implementations, the coffee bean information may include not only the weight of the coffee beans but also the type and roasting method. This coffee bean information can be determined through user input or automatically acquired by a weighing component on an electronic scale. For example, the weighing component may be equipped with a photosensitive sensor to determine the particle size of the coffee beans by measuring their transmittance and density, and then determine their corresponding type based on the particle size. Alternatively, the electronic scale may be equipped with a camera module to capture images of the coffee beans to be measured, analyze the images to determine whether the beans are dark or light roasts, and thus determine their roasting method. Image analysis can also be used to determine the type of coffee beans, thereby confirming the aforementioned coffee bean information.

[0036] In S202, based on the coffee bean information and the brewing process information, the caffeine information corresponding to the weight of the coffee beans is determined; the brewing process information includes the brewing time of the coffee beans.

[0037] In this embodiment, after obtaining the coffee bean information, the electronic scale can also obtain the brewing process information related to the coffee beans. This brewing process information can be manually entered by the user or automatically obtained by the electronic scale; the specific method of acquisition can be determined according to the actual situation and is not limited here.

[0038] In some possible implementations, the aforementioned brewing process information can be obtained through a timing module on an electronic scale. After acquiring the weight of the coffee beans, the scale can receive a user-initiated timing start command and stop timing when it detects that the weighing reading is not zero. Since the weighing reading is not zero, it can be recognized that the coffee liquid has been dispensed, meaning the coffee beans have been brewed. The brewing time is calculated based on the duration between the time the timing start command is received and the time when the weighing reading is not zero, and brewing process information is generated based on this brewing time.

[0039] In some possible implementations, the above brewing process information may also include the method of grinding the coffee beans and / or the method of brewing the coffee beans.

[0040] In some possible implementations, the electronic scale can store default brewing information. If it does not receive any modification to the brewing process from the user or send any other brewing process information, the electronic scale can use the aforementioned default brewing information as the brewing process information for this coffee bean.

[0041] In some possible implementations, the electronic scale can determine the brewing process information through a touch module or a voice recognition module, based on the user's touch operation or voice signal. For example, the touch module may include multiple brewing method selection controls, allowing the user to select the target brewing method for the coffee being brewed. The electronic scale can then determine the corresponding brewing process information based on the user's selection.

[0042] In this embodiment, the total amount of caffeine contained in coffee beans varies depending on their weight. Specifically, the heavier the coffee beans, the higher their caffeine content. The brewing process also affects the total amount of caffeine extracted from the coffee beans. Therefore, the electronic scale can combine these two pieces of information to determine the total amount of caffeine that can be extracted from brewing a given weight of coffee beans, i.e., the aforementioned caffeine information.

[0043] In this embodiment, the electronic scale can store a corresponding caffeine conversion function. The electronic scale imports the obtained coffee bean weight and the relevant parameters in the above-mentioned brewing process information into the above-mentioned caffeine conversion function to determine the amount of caffeine that can be extracted in this brewing process, and obtains the above-mentioned caffeine information based on the amount of caffeine.

[0044] In some possible implementations, the above brewing process information may include multiple brewing methods, that is, the user can choose the target brewing method from multiple brewing methods. In order to facilitate the user's selection, the electronic scale can determine the amount of caffeine that can be extracted by different brewing methods and establish the correspondence between different brewing methods and the amount of caffeine, thereby generating the above caffeine information.

[0045] In S203, some or all of the caffeine information is displayed on the screen of the electronic scale.

[0046] In this embodiment, after determining the caffeine information corresponding to the weight of the coffee beans, the electronic scale can display the weight of the coffee beans on the scale, and can also display some or all of the caffeine information. Specifically, the electronic scale can display the weight of the coffee beans and the caffeine information sequentially on the display screen according to a preset display order. For example, it can display the weight of the coffee beans first, then the caffeine information, and so on, rotating them on the display screen according to this display order. If the display area of ​​the screen is large, the weight of the coffee beans and the caffeine information can also be displayed simultaneously. The specific display method can be set according to the size of the display screen and display requirements; no limitation is placed on the display method here.

[0047] For example, Figure 3 A schematic diagram showing caffeine information provided in an embodiment of this application is illustrated. See also... Figure 3 As shown, the display screen of the above-mentioned electronic scale includes two display areas: area 31 for displaying the weight of coffee beans and area 32 for displaying caffeine information. The caffeine information can display the brewing method of coffee beans as "hand pour" and the amount of caffeine as "200 mg".

[0048] In some possible implementations, if the weight of the coffee beans to be measured increases or decreases, the caffeine information can be updated based on the updated coffee bean weight, and the updated caffeine information can be re-displayed on the display screen. This achieves the purpose of dynamically displaying the coffee bean weight and caffeine information, improving the timeliness and accuracy of information display.

[0049] As can be seen from the above, the control method for an electronic scale provided in this application acquires coffee bean information and brewing process information when the electronic scale measures coffee beans. Based on these two pieces of information, the total amount of caffeine contained in the coffee beans is determined, thereby obtaining the corresponding caffeine information. Finally, some or all of the caffeine information is displayed on the screen of the electronic scale, achieving the goal of intuitively displaying the caffeine content. Compared with existing electronic scale technology, this application, when weighing coffee beans, can not only obtain the weight of the coffee beans but also determine the caffeine information corresponding to that weight based on the coffee bean weight and brewing process information. This increases the types of information that the electronic scale can display and makes it convenient to determine the amount of caffeine contained in coffee before brewing, improving the convenience of obtaining caffeine information and meeting the daily needs of users.

[0050] Figure 4 A flowchart illustrating the specific implementation of a control method for an electronic scale according to the second embodiment of this application in step S202 is shown. See also Figure 4 As shown, relative to Figure 2 The embodiment provided in this application provides a control method for an electronic scale, which includes steps S2021 to S2025 in step S202, as described in detail below: Furthermore, as another embodiment of this application, the brewing process information includes the grind size of the coffee beans and the brewing method; The step of determining the caffeine information corresponding to the weight of the coffee beans based on the coffee bean information and brewing process information includes: In S2021, the baseline caffeine coefficient corresponding to the coffee bean type is determined based on the coffee bean type in the coffee bean information.

[0051] In this embodiment, the coffee bean information may include not only the weight of the coffee beans, but also the type of coffee beans. The types of coffee beans can be distinguished according to their place of origin, such as coffee beans from Colombia or coffee beans from Indonesia. They can also be classified according to their roasting method. For example, the coffee beans may include dark roast coffee beans, medium roast coffee beans, and light roast coffee beans. The specific classification method of coffee bean types can be determined according to the actual situation, and the classification method of coffee bean types is not limited here.

[0052] In this embodiment, the coffee bean type can be manually entered by the user, or selected via a touch module, or obtained automatically by scanning the QR code on the coffee bean packaging bag using the camera module on the electronic scale, or obtained through other methods. The method of obtaining the coffee bean type is not limited here.

[0053] In this embodiment, since different types of coffee beans contain different amounts of caffeine per unit weight, the electronic scale can record the correspondence between different types of coffee beans and the baseline caffeine content per unit weight. After obtaining the above-mentioned types of coffee beans, the electronic scale can query the above-mentioned correspondence to determine the baseline caffeine coefficient corresponding to the type of coffee beans, that is, the caffeine content per unit weight.

[0054] In some possible implementations, the correspondence between the coffee bean types and the baseline caffeine content per unit weight can be obtained by the electronic scale downloading from the cloud server, or the electronic scale can upload the obtained coffee bean types to the cloud server, and the cloud server can provide feedback on the baseline caffeine coefficient corresponding to the coffee bean type.

[0055] In S2022, the caffeine fluctuation range is determined based on the weight of the coffee beans and the reference caffeine coefficient.

[0056] In this embodiment, the aforementioned benchmark caffeine coefficient can be used to determine the caffeine content per unit weight. The electronic scale can calculate the product between the weight of the coffee beans and the benchmark caffeine coefficient, thereby calculating the expected total caffeine amount corresponding to the weight of the coffee beans. Based on the caffeine fluctuation coefficient corresponding to the type of coffee beans, the scale determines the lower limit and upper limit of the caffeine content corresponding to the expected total caffeine amount, thereby determining the aforementioned caffeine fluctuation range.

[0057] For example, the caffeine weight is 20 grams, and the baseline caffeine coefficient is 10 mg / g. By calculating the product between the caffeine weight and the baseline caffeine coefficient, the expected total caffeine amount can be calculated to be 200 mg, and the corresponding caffeine fluctuation coefficient is 10%. That is, the lower limit is (200-200*10%) mg, which is 180 mg. Similarly, the upper limit can be calculated to be 220 mg, that is, the caffeine fluctuation range is 180 mg to 220 mg.

[0058] In S2023, the caffeine fluctuation range is calibrated by using the extraction efficiency corresponding to the grinding particle size to obtain the calibrated fluctuation range.

[0059] In this embodiment, when weighing coffee beans, the coffee beans to be measured can be in a state unground, i.e., not coffee powder, but in their raw bean state. The electronic scale can then obtain the corresponding particle size of the coffee beans to be ground. This particle size can be manually input by the user, a default setting, or sent to the electronic scale by a smart home appliance (such as a smart coffee grinder). The specific method for obtaining the particle size can be determined according to the actual situation. Optionally, if the coffee beans are already ground, i.e., the coffee beans to be measured are already ground coffee powder, the electronic scale can determine the particle size based on the particle size of the powder.

[0060] In this embodiment, the size of the ground particles affects the caffeine extraction efficiency. Different types of coffee beans may have different recommended particle sizes. The electronic scale can determine the recommended particle size based on the coffee bean type in the coffee bean information, and then determine the difference between the current ground particle size of the coffee bean to be measured and the recommended particle size, thereby determining the extraction efficiency. For example, if the ground particle size matches the recommended particle size, the extraction efficiency can be 100%. The greater the difference, the lower the extraction efficiency. The caffeine fluctuation range is then calibrated based on the determined extraction efficiency to obtain a corresponding calibrated fluctuation range.

[0061] In S2024, the amount of caffeine corresponding to each brewing method is determined based on the extraction coefficient corresponding to each candidate brewing method, the brewing time, and the calibration fluctuation range.

[0062] In this embodiment, the candidate brewing methods can be preset by the user or set by the electronic scale by default. The specific method for obtaining the candidate brewing methods can be set according to the actual situation and is not limited here. For example, the candidate brewing methods can be stored in the brewing process information.

[0063] In this embodiment, different brewing methods correspond to different extraction coefficients. For example, brewing with a coffee machine results in the highest extraction coefficient, while brewing by hand-drip method results in the lowest extraction coefficient. Based on the brewing method, the corresponding extraction coefficient is determined. Then, the electronic scale can combine the brewing time determined by the timing module, the extraction coefficient, and the calibration fluctuation range to determine the corresponding amount of caffeine within the calibration fluctuation range.

[0064] For example, the desired brewing time can be determined based on the weight of the coffee beans. The smaller the difference between the brewing time and the desired time, the higher the extraction efficiency; conversely, the larger the difference, the lower the extraction efficiency. For instance, if the brewing time matches the desired time, the extraction efficiency is 1. It should be noted that the electronic scale can dynamically update the caffeine content mentioned above based on changes in brewing time, and update the caffeine content displayed on the display module accordingly.

[0065] In S2025, the caffeine information is obtained based on the correspondence between all the brewing methods and the amount of caffeine.

[0066] In this embodiment, after determining the amount of caffeine corresponding to different brewing methods, the electronic scale can establish a correspondence between the two and obtain the above-mentioned caffeine information based on the correspondence between all brewing methods and caffeine.

[0067] In this embodiment, the electronic scale can determine the range of caffeine content for a given weight based on the type of coffee beans and the particle size of the grind. Then, based on different brewing methods, it can determine the corresponding amount of caffeine from the aforementioned calibration fluctuation range, thereby obtaining caffeine information and improving the accuracy of the caffeine information.

[0068] Figure 5 A flowchart illustrating the specific implementation of a control method for an electronic scale according to the third embodiment of this application at step S2024 is shown. See also... Figure 5 As shown, relative to Figure 4 The embodiment provided in this application provides a control method for an electronic scale, which includes steps S501 to S504 in step S2024, as described in detail below: Furthermore, as another embodiment of this application, determining the caffeine amount corresponding to each brewing method based on the extraction coefficient corresponding to each candidate brewing method and the calibration fluctuation range includes: In S501, when the brewing method is a pour-over brewing method, a first extraction coefficient corresponding to the pour-over brewing method is determined based on the roasting method of the coffee beans and the brewing time; the first extraction coefficient is used to determine the amount of caffeine corresponding to the pour-over brewing method.

[0069] In this embodiment, the above-mentioned candidate brewing methods may include at least one of the following three types: hand-drip brewing, moka pot brewing, and coffee machine brewing. The specific types of the above-mentioned candidate brewing methods can be set according to the actual situation, and no limit is imposed on the candidate brewing methods here.

[0070] In this embodiment, the electronic scale can determine the roasting method corresponding to the coffee beans to be measured, such as dark roast, light roast, and medium roast, when the candidate brewing methods include pour-over brewing. Since pour-over brewing primarily uses 95°C water to brew coffee powder, without a high-pressure, high-temperature environment, its caffeine extraction efficiency is highly correlated with its roasting method. Based on this, the electronic scale can determine the roasting method corresponding to the coffee beans to be measured from the coffee bean information, thereby determining its corresponding extraction efficiency. Different roasting methods use different rated water temperatures; for example, the rated water temperature for light roast coffee beans can be 90°C, while for dark roast coffee beans, the rated water temperature can be 96°C. Users can choose to brew water based on their actual usage, such as using water boiled in an electric kettle at 100 degrees Celsius, or a kettle with precise temperature control at a specified temperature, such as 95 degrees Celsius. The electronic scale can calculate the difference between the user-set desired water temperature and the rated water temperature corresponding to the baking method, thereby determining the corresponding first extraction coefficient. The smaller the difference between the desired water temperature and the rated water temperature, the higher the value of the first extraction coefficient; conversely, the larger the difference, the lower the value of the first extraction coefficient.

[0071] In S502, when the brewing method is a non-pour-over brewing method, a second extraction coefficient corresponding to the non-pour-over brewing method is determined based on the weight of the coffee beans and the weight of the coffee liquid.

[0072] In this embodiment, in the case of non-pour-over brewing, the electronic scale can determine the amount of coffee liquid dispensed during the brewing process, i.e., the weight of the coffee liquid, through the weighing component. Based on the weight of the coffee beans and the amount of coffee liquid dispensed, the coffee-to-liquid ratio is determined. Then, through a preset conversion function, the second extraction coefficient corresponding to the coffee-to-liquid ratio is determined. Subsequently, the amount of caffeine in the coffee liquid can be determined through the second extraction coefficient, thus realizing the automatic calculation of caffeine content in the non-pour-over method.

[0073] Alternatively, in addition to determining the second extraction coefficient in the manner described above, different methods for determining the extraction coefficient can be used depending on the brewing equipment used.

[0074] For example, when the brewing method is a Moka pot brewing method, the extraction ratio of the Moka pot can be determined according to the grinding particle size and the first model of the Moka pot.

[0075] In this embodiment, when the candidate brewing method includes the Moka pot brewing method, the first model of the Moka pot can be determined. The developer of the electronic scale can determine the extraction effect of different models of Moka pots when brewing coffee beans with different grind sizes through sample experiments, that is, determine the extraction ratio corresponding to different models for different grind sizes, thereby constructing a correspondence table between Moka pot model, grind size, and extraction ratio. For example, Table 1 shows a correspondence table between Moka pot model, grind size, and extraction ratio provided in an embodiment of this application. Referring to Table 1, for the same model of coffee pot, different extraction ratios can be determined based on the actual grind size of the coffee powder. The electronic scale can determine the extraction ratio corresponding to different grind sizes based on the first model of the Moka pot, and then determine the extraction ratio corresponding to the first model when brewing coffee beans with a specific grind size based on the grind size in the brewing process information. For example, if the Moka pot model is Model 1 and the grind size is 600 micrometers, its corresponding extraction ratio can be determined to be 90% according to Table 1.

[0076]

[0077] Table 1 In this embodiment, after determining the extraction ratio corresponding to the model of the Moka pot, the electronic scale can determine the expected brewing volume of coffee liquid that can be brewed based on the current coffee bean weight, and determine the rated brewing volume that the Moka pot can extract in one use based on the first model of the Moka pot. It can then determine whether the expected brewing volume corresponding to the coffee bean weight matches the rated brewing volume corresponding to the Moka pot. Based on the degree of deviation between the expected brewing volume and the rated brewing volume, the corresponding fluctuation factor can be determined. Then, based on the determined extraction ratio and the fluctuation factor, the second extraction coefficient corresponding to brewing with the Moka pot can be calculated.

[0078] For example, if the brewing method is a coffee machine brewing method, the extraction coefficient corresponding to the coffee machine brewing method is determined according to the second model of the coffee machine.

[0079] In this embodiment, the electronic scale can also determine the second model of the coffee machine. Different models of coffee machines will have different extraction ratios. The electronic scale can record a correspondence table between different coffee machines and extraction ratios. Based on the second model of the coffee machine used this time, the rated extraction ratio corresponding to that model of coffee machine can be determined from the above correspondence table.

[0080] In this embodiment, the electronic device can determine the corresponding extraction coefficient according to the characteristics of different brewing methods, thereby improving the accuracy of determining the amount of caffeine corresponding to different brewing methods and thus improving the user experience.

[0081] Figure 6 A flowchart illustrating the specific implementation of a control method for an electronic scale according to the fourth embodiment of this application before S2023 is shown. See also... Figure 6 As shown, relative to Figure 4 In the embodiment provided by this application, a control method for an electronic scale further includes steps S601-S602 before step S2023, as described in detail below: Furthermore, as another embodiment of this application, before calibrating the caffeine fluctuation range using the extraction efficiency corresponding to the grinding particle size to obtain the calibrated fluctuation range, the method further includes: In S601, the average coffee particle size corresponding to the coffee beans is obtained.

[0082] In this embodiment, in addition to the weight of the coffee beans, the electronic scale can also determine the average coffee bean size, i.e., the size of each coffee bean, based on the coffee bean information. Where the coffee bean information includes the type of coffee bean, for example, it may include the origin of the coffee beans or the type of coffee beans. The electronic scale can determine the corresponding average coffee bean size based on the type of coffee beans mentioned above.

[0083] In some possible implementations, the electronic scale can also acquire an image of the coffee beans to be weighed, analyze the image to determine the outline information of each coffee bean, then determine the size of each coffee bean based on the outline information, and then determine the average coffee particle size mentioned above based on the size of all identified coffee beans.

[0084] In step S602, the extraction efficiency is determined based on the average coffee particle size and the grind particle size; specifically, the extraction efficiency is:

[0085] Wherein, Eff(SizeCoff, Sizedust) is the extraction efficiency; SizeCoff is the average coffee particle size; Sizedust is the grinding particle size; BaseCoff is the reference coffee particle size; Basedust is the reference grinding particle size; and η is a preset coefficient.

[0086] In this embodiment, the electronic scale determines the size ratio between the coffee bean size and the reference coffee bean size, and can then determine the corresponding method for calculating the extraction efficiency. Since each coffee bean has a certain upper limit on the caffeine content—that is, a larger coffee bean does not necessarily mean a higher caffeine content—and some coffee beans exceeding the rated size have a smaller difference in caffeine content compared to beans of the rated size, the calculation method can be applied based on the difference between the average coffee bean size to be measured and the reference coffee bean size.

[0087] In this embodiment, when the average coffee particle size is less than the aforementioned benchmark coffee particle size, the electronic scale can calculate the corresponding extraction efficiency based on the average coffee particle size, benchmark coffee particle size, grinding particle size, and benchmark grinding particle size. Conversely, when the average coffee particle size is greater than the aforementioned benchmark coffee particle size, the electronic scale can subtract a preset coefficient from the ratio between the average coffee particle size and the benchmark coffee particle size to obtain a more accurate proportion of caffeine contained in each coffee bean. Then, based on the aforementioned caffeine proportion, grinding particle size, and benchmark grinding particle size, the aforementioned extraction efficiency can be calculated.

[0088] In this embodiment of the application, the extraction efficiency is calculated by adopting a corresponding method based on the size relationship between the average coffee bean size and the benchmark coffee bean size, which can improve the accuracy of subsequent caffeine calculation.

[0089] Figure 7 A flowchart illustrating the specific implementation of a control method for an electronic scale according to the fifth embodiment of this application in step S203 is shown. See also... Figure 7 As shown, relative to Figure 2 , Figure 4 , Figure 5 as well as Figure 6 In any of the embodiments described above, the control method for an electronic scale provided in this application includes S2031 to S2033 in step S203, as specifically described below: In S2031, the system receives user input regarding the target caffeine; the input is triggered by the input control of the electronic scale or by the voice recognition module.

[0090] In this embodiment, the electronic scale may be equipped with a voice recognition module or an input control, allowing the user to input the desired amount of caffeine intake, i.e., the target caffeine amount mentioned above. For example, by using the voice signal "I wish to consume 200 mg of caffeine today," the electronic scale can generate a trigger command containing the target caffeine amount; alternatively, the user can adjust the display reading of the caffeine amount display area to 200 mg using a knob on the electronic scale and click the "Confirm" button, allowing the electronic scale to generate a trigger command containing 200 mg of caffeine based on the input operation.

[0091] In S2032, the weight of target coffee beans matching the target caffeine is determined based on the target caffeine and the brewing process information.

[0092] In this embodiment, the electronic scale can deduce the weight of coffee beans based on the target caffeine and the brewing process information determined above, and determine the target weight of coffee beans from which the corresponding amount of caffeine can be extracted, thereby enabling the user to weigh coffee beans.

[0093] Figure 8 A flowchart illustrating the specific implementation of a control method for an electronic scale according to the sixth embodiment of this application in step S203 is shown. See also... Figure 8 As shown, relative to Figure 2 , Figure 4 , Figure 5 as well as Figure 6 In any of the embodiments described above, the control method for an electronic scale provided in this application includes steps S801 to S803 in step S203, as specifically described below: Furthermore, as another embodiment of this application, displaying part or all of the caffeine information on the display screen of the electronic scale includes: In S801, the target caffeine for the user is determined based on the user's activity information.

[0094] In this embodiment, the electronic scale can not only display the amount of caffeine contained in the coffee beans, but also select the brewing method that matches the user's desired caffeine level from a variety of candidate brewing methods, thereby guiding the user to use the appropriate brewing method to brew the coffee beans. The aforementioned activity information may include information such as the user's working hours and work type. The specific types of activity information can be set according to actual conditions, and may specifically include information reflecting the duration of the user's required concentration.

[0095] In some possible implementations, the aforementioned activity information can be manually entered by the user, such as the length of working hours or the time period of working hours, or the electronic scale can determine the user's activity information by communicating with the user's smart terminal and using the location information of the smart terminal.

[0096] In this embodiment, the electronic scale can determine the user's attention level based on activity information, and then determine the corresponding target caffeine amount based on the attention level. The higher the attention level, the higher the corresponding target caffeine amount.

[0097] Furthermore, as another embodiment of this application, the activity information includes the user's location information and application usage information; The step of determining the target caffeine for a user based on their activity information includes: In S801.1, the location information sent by the user's electronic device is received, and the user's working time is determined based on the location information.

[0098] In this embodiment, the electronic scale can establish a communication connection with the user's electronic device, such as a smartphone, smartwatch, or other smart device. The electronic device can send the acquired location information to the electronic scale, so that the electronic scale can perform cluster analysis on the location information to determine the user's corresponding work location and the duration of stay at the work location, i.e., determine the user's working time.

[0099] In S801.2, the target caffeine is determined based on the working time and the concentration level corresponding to the application usage information.

[0100] In this embodiment, usage information of applications used on the user's electronic device can also be sent to the electronic scale. The electronic scale can analyze the application usage information, such as extracting applications related to the work type and the corresponding usage duration, thereby determining the corresponding focus level based on the usage duration of the work application. Then, based on the focus level and the usage duration, the target caffeine amount can be determined. Specifically, the longer the usage duration, the greater the target caffeine amount; the higher the focus level, the greater the target caffeine amount.

[0101] In this embodiment of the application, the electronic scale can determine the target amount of caffeine that matches the user's behavior by obtaining location information and application usage information, thereby improving the accuracy of the subsequent recommended brewing method and thus improving the user experience.

[0102] In S802, based on the amount of caffeine corresponding to each brewing method in the caffeine information, the brewing method with the smallest difference from the target caffeine is determined as the recommended brewing method.

[0103] In this embodiment, after determining the user's target caffeine amount, the electronic scale can calculate the difference between the caffeine amount of different brewing methods and the target caffeine amount, and select the brewing method with the smallest difference as the recommended brewing method. That is, the caffeine content of the coffee liquid obtained by brewing coffee beans using this brewing method can meet the user's life and work needs.

[0104] In S803, the recommended brewing method and the corresponding amount of caffeine are displayed on the screen.

[0105] In this embodiment, in addition to displaying the weight of coffee beans on the display screen, the electronic scale can also display the aforementioned recommended brewing method and the corresponding amount of caffeine on the display screen, thereby enabling the scale to recommend brewing methods to users and improve their user experience.

[0107] In this embodiment, the electronic scale can be equipped with a voice recognition module. The voice recognition module can acquire the user's voice signal. For example, if the user says a keyword containing a start command, the electronic scale can generate a corresponding semantic acquisition command, acquire the subsequent voice signal, and perform signal analysis on the subsequent voice signal to convert the voice signal into text information. Then, semantic analysis is performed on the text information to determine the coffee bean information and brewing process information from the text signal converted from the user's voice, thereby improving the efficiency of information acquisition.
