Description

Technical Field

[0001] The present invention belongs to the technical field of beverage preparation, and in particular relates to a coffee machine and a control method and a storage medium thereof. Background Art

[0002] As people's living standards improve, the demand for coffee quality and personalization is increasing. In the current coffee machine technology field, there are many aspects that need to be improved.

[0003] In terms of water purification, traditional coffee machines have limited ability to purify water entering the machine, which can easily lead to scale accumulation in the boiler, pump and pipes. This will not only shorten the service life of the boiler, but also increase the cost and difficulty of maintaining the coffee machine.

[0004] In terms of flavor addition, most traditional coffee machines can only directly use the water supply from the water source to brew coffee, and cannot accurately add flavor elements, making it difficult to meet consumers' pursuit of diverse tastes. For example, when faced with coffee beans of different origins and roasting degrees, traditional coffee machines cannot specifically add appropriate flavor elements to enhance the taste. Using a coffee machine to brew a cup of good flavored coffee requires extremely high water quality. Usually, a certain amount of calcium, magnesium, sodium and other ions are required in the brewing water source to fully extract the flavor from the coffee powder. However, these ions will form a large amount of crystals when heated in pipes and boilers, causing the boiler water volume to decrease and the water quality to deteriorate. Cleaning is very complicated, especially for pipes with throttling holes, which are prone to blockage, thereby affecting the service life of the coffee machine. Although frequent cleaning can alleviate this problem, the complicated cleaning process not only consumes time and energy, but may also cause damage to the precision parts inside the coffee machine.

[0005] There are significant differences in water quality in different regions around the world. As one of the important indicators for measuring water quality, the water hardness value varies greatly in different regions. Even if the same coffee beans and brewing methods are used, the flavor, taste and aroma of the brewed coffee will be very different due to different water quality. This not only brings troubles to coffee lovers, but also poses challenges to the standardization development of the coffee industry. Summary of the invention

[0071] In the embodiments of the present invention, the term "plurality" refers to two or more, and other quantifiers are similar thereto.

[0072] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will elaborate on each embodiment of the present invention in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the present invention, many technical details are provided to help readers better understand the present invention. Nevertheless, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present invention can still be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation to the specific implementation of the present invention. The various embodiments can be combined and cross-referenced with each other on the premise of no contradiction.

[0073] The present invention provides a coffee machine 100, which is used for brewing and extracting coffee liquid. It can be a beverage preparation device that grinds granular coffee beans to obtain coffee powder and then can extract and brew the coffee powder to finally obtain a coffee beverage. It can also be a beverage preparation device that extracts and brews pre-prepared coffee powder to finally obtain a coffee beverage.

[0074] In one embodiment, please refer to Figure 1 , the coffee machine 100 includes a liquid supply pipeline, a hot water boiler 30, a brewing device 50, and an ingredient adding device 40.

[0075] The liquid supply pipeline is used to transport the water liquid for preparing coffee beverages in the entire coffee machine 100 system. Its water inlet end is suitably connected to the water purification device 10. This is because in a traditional coffee machine 100, after long-term use, impurities, minerals, etc. in the water source are likely to form scale in brewing components such as the hot water boiler 30, the pump body 20, and the pipeline. Especially in the hot water boiler 30 and its downstream components, scale is very easy to accumulate under the action of hot water. Scale not only reduces the heat exchange efficiency of the hot water boiler 30, resulting in energy waste, but also affects the normal operation of the pump body 20, increasing the maintenance cost and difficulty, and even shortening the service life of the coffee machine 100. By purifying the water source through the water purification device 10, most of the impurities and harmful substances in the water can be effectively removed.

[0076] The specific type of the water purification device 10 can be selected according to the water source situation. For example, it can include an RO reverse osmosis filter, which can not only filter out impurities in the water but also remove dissolved salts in the water, such as calcium, magnesium, and other ions, thereby providing high-quality water for the coffee machine 100 and reducing the generation of scale from the source. The water outlet end of the liquid supply pipeline is connected to the beverage outlet 70, and the coffee beverage after a series of treatments and brews flows out through this beverage outlet 70 for direct enjoyment by the user.

[0077] The hot water boiler 30 is provided on the liquid supply pipeline, and its main function is to heat the water flowing in from the liquid supply pipeline to a temperature suitable for extracting coffee liquid. Inside the hot water boiler 30, there are usually equipped with heating elements and a temperature control system. The heating elements can be resistance wires, heating tubes, etc., which convert electrical energy into heat energy to heat the water. The temperature control system can accurately control the water temperature. When the water temperature reaches the set value, it automatically stops heating. When the water temperature drops, it can start heating in time to ensure that the water temperature always remains within a suitable range.

[0078] The brewing device 50 is provided on the liquid supply pipeline and is located downstream of the hot water boiler 30. When the hot water flows out of the hot water boiler 30, it enters the brewing device 50 and makes full contact with the coffee powder to achieve the coffee extraction process. The type and structure of the brewing device 50 are not limited. For example, it can include a brewing cylinder, a piston, etc. During the brewing process, the brewing device 50 itself requires certain flavor elements. In the present invention, the flavor elements mainly refer to some minerals required for coffee extraction, such as calcium ions, magnesium ions, bicarbonates, etc. These minerals play an important role in the coffee extraction process. They can undergo chemical reactions with the components in the coffee beans, affecting the taste and flavor of the coffee. For example, calcium ions can enhance the bitterness and mellow feeling of the coffee, magnesium ions help to enhance the sweetness and aroma of the coffee, and bicarbonates can adjust the acidity and alkalinity of the coffee, making the coffee taste more balanced.

[0079] Specifically, when the flavor elements include metal ions, the component adding device 40 is arranged such that the TDS value of the water liquid flowing to the brewing device 50 is increased relative to the water inlet end of the liquid supply pipeline. That is to say, the component adding device 40 will accurately add flavor elements containing metal ions to the liquid supply pipeline according to preset conditions, appropriately increasing the total dissolved solids (TDS value) of the water liquid to optimize the coffee extraction effect and improve the coffee taste. Preferably, the component adding device 40 is arranged such that the TDS value of the water liquid flowing to the brewing device 50 is greater than 100 mg / L and less than 200 mg / L. Within this TDS value range, it can ensure that there are sufficient dissolved substances in the water to participate in the coffee extraction, and it will not affect the coffee flavor due to excessive content.

[0080] In an alternative embodiment, when the flavor elements include calcium ions and magnesium ions, the component adding device 40 is arranged such that the ratio of calcium ions to magnesium ions in the water liquid flowing to the brewing device 50 is greater than or equal to 1.8 and less than or equal to 2.2. By strictly controlling the ratio of these two ions, the synergistic effect of them in coffee extraction can be better exerted, ensuring that the coffee achieves balance in aspects such as bitterness, mellow feeling, sweetness, and aroma.

[0081] In yet another alternative embodiment, the ingredient adding device 40 is arranged such that the pH value of the aqueous liquid flowing to the brewing device 50 is greater than or equal to 6.5 and less than or equal to 7.5. A suitable pH value helps to fully extract the coffee ingredients, ensuring the coffee taste while avoiding adverse effects on the human body.

[0082] In yet another alternative embodiment, the ingredient adding device 40 is arranged such that the content of iron in the aqueous liquid flowing to the brewing device 50 is less than or equal to 0.3 mg / L and the content of manganese is less than or equal to 0.1 mg / L. Controlling the contents of iron and manganese prevents them from excessively affecting the taste and quality of the coffee, ensuring the pure flavor of the coffee.

[0083] In this embodiment, the coffee machine 100 further includes an ingredient adding device 40. The ingredient adding device 40 is arranged between the hot water boiler 30 and the brewing device 50, and its function is to add the required flavor elements to the liquid supply pipeline. In this way, it not only improves the scaling situation of minerals and the like in the hot water boiler 30, but also can accurately add the required flavor elements to the brewing device 50 according to the taste requirements of the brewed coffee, meeting the pursuit of consumers for diversified and precise tastes. The emergence of the ingredient adding device 40 solves this problem. It can add various flavor elements according to different requirements to prepare coffee with the most suitable taste and flavor for the customer's needs.

[0084] In an alternative embodiment, in addition to the above-mentioned minerals, the flavor elements may further include flavor elements such as vanilla, caramel, and chocolate. For example, when using lightly roasted coffee beans, since their own flavor is relatively light, some vanilla flavor elements can be added through the ingredient adding device 40 to enhance the aroma and layering of the coffee; when making a caramel latte, an appropriate amount of caramel flavor elements can be added to make the coffee have a strong caramel taste. In this way, by precisely controlling the addition ratio of the flavor elements, the taste of the brewed coffee can be made more rich and diverse, meeting the personalized needs of different consumers.

[0085] In an alternative embodiment, the coffee machine 100 is further provided with a water purification outlet 60 for discharging purified water. In this way, the coffee machine 100 can be used to discharge the purified water purified by the purification device, so that the coffee machine 100 can provide purified water. Specifically, the coffee machine 100 further includes a water outlet pipeline, and the water outlet pipeline communicates the hot water boiler 30 and the water purification outlet 60. The setting of the water outlet pipeline brings more usage scenarios and functions to the coffee machine 100. For example, users can use the hot water provided by the coffee machine 100 to brew other beverages or drink directly. This function increases the practicality and versatility of the coffee machine 100 and meets the needs of users in different scenarios.

[0086] Based on the above embodiments, the coffee machine 100 further includes a pump body 20. The pump body 20 is arranged on the liquid supply pipeline and is located upstream of the hot water boiler 30. In this embodiment, the pump body 20 is used to drive the liquid to flow from the water source to the beverage outlet 70 and the purified water outlet 60. When the pump body 20 works, it generates a certain pressure, sucks the water in the water purification device 10 into the liquid supply pipeline, and transports the water to the hot water boiler 30 with a stable pressure. Preferably, the pump body 20 can adjust its power according to its actual working requirements to adjust the flow rate of the water in the liquid supply pipeline to meet the extraction requirements of different coffee liquids.

[0087] The ingredient adding device 40 is used to add flavor elements to the liquid supply pipeline according to the brewing requirements. The ingredient adding device 40 in this embodiment includes a storage mechanism and a release mechanism. Among them, the storage mechanism is used to store the flavor elements to be added, and the release mechanism adds the flavor elements in the storage mechanism to the liquid supply pipeline according to the requirements through actions such as opening and puncturing.

[0088] In an alternative embodiment, the storage mechanism stores various types of flavor capsules. The flavor capsules can be pre-encapsulated disposable products or reusable products that can be repeatedly opened and encapsulated. In this embodiment, the flavor element ratios stored in different types of flavor capsules are different, which provides a more abundant choice for the finished flavor and taste of the brewed coffee beverage. Preferably, the flavor capsules are designed with sealed packaging, which can effectively prevent the volatilization and deterioration of the flavor elements, ensuring the quality and stability of the flavor elements. At the same time, the capsule form is also convenient for storage and management, and users can replace different flavor capsules according to actual needs. In this embodiment, the release mechanism is used to put the flavor elements in at least one of the flavor capsules into the liquid supply pipeline according to a preset ratio. The preset ratio can be set according to different coffee beverages or the personalized needs of users. The working principle of the release mechanism can be based on mechanical transmission, electronic control, etc. For example, an electric push rod type or puncture type release mechanism is adopted. When receiving the instruction issued by the control system, the flavor capsule is opened, so that the flavor elements in the capsule flow into the liquid supply pipeline. Preferably, during the putting process, the release mechanism can accurately control the action speed and / or opening time of the mechanical transmission, etc., to achieve precise control of the amount of flavor elements put in, ensuring that the ratio of the flavor elements put in meets the preset requirements. This method of using flavor capsules is not only convenient to operate and simple in structure, but also can ensure that the coffee flavor brewed each time is consistent, providing consumers with a stable taste experience.

[0089] In another alternative embodiment, the storage mechanism is used to store multiple containers, and the types of flavor elements stored in different containers are different. The containers in the storage mechanism can adopt different materials and specifications to meet the storage requirements of different flavor elements. For example, for liquid flavor elements, sealed plastic bottles or glass bottles can be used for storage, and for solid flavor elements, sealed plastic bags or metal cans can be used for storage. Clear labels can be marked on different containers to indicate the types of flavor elements stored and usage instructions, facilitating users to identify and use. The release mechanism is used to deliver the flavor elements in at least one container to the liquid supply pipeline according to a preset ratio. This method is more flexible and can achieve more diverse flavor combinations. For example, when a user wants a cup of coffee with a unique flavor, they can, according to their preferences, select appropriate flavor elements from different containers through the release mechanism and put them into the liquid supply pipeline in a certain proportion. The release mechanism can adopt corresponding methods to release the flavor elements for each container. Specifically, reference can be made to the previous embodiment, which will not be elaborated here. Moreover, when the flavor elements in a certain container are used up, only this container needs to be replaced, without the need to replace the whole as in the case of using flavor capsules, which is convenient and fast and reduces the usage cost.

[0090] Based on the above embodiments of the coffee machine 100, the present invention provides a control method for the coffee machine 100. In this embodiment, the embodiments of the control method of the coffee machine 100 include the above embodiments of the coffee machine 100, and the beneficial effects of the above coffee machine 100 can be applied to the control method of the coffee machine 100; similarly, the above embodiments of the coffee machine 100 can include the embodiments of the control method of the coffee machine 100, and the beneficial effects of the control method of the coffee machine 100 can be applied to the above coffee machine 100.

[0091] The implementation details of the control method of the coffee machine 100 according to the first embodiment of the present invention will be described below. The following content is only the implementation details provided for convenient understanding and is not necessary for implementing this solution.

[0092] The specific process of this embodiment is as Figure 2 shown and specifically includes:

[0093] Step S1: Obtain the ingredient addition formula.

[0094] The ingredient addition formula determines the types and proportions of flavor elements to be added to the liquid supply pipeline. In specific implementations, there can be multiple ways to obtain the ingredient addition formula. One way is to determine the types and proportions of flavor element additions (i.e., the ingredient addition formula) based on the user's order information. The user's order information can include, but is not limited to, the type of beverage selected by the user, taste preferences, etc., such as mocha, cappuccino, rich, fresh, etc. In this way, the coffee machine 100 can obtain the corresponding ingredient addition formula according to the user's selection. Another way is to retrieve a preset coffee beverage formula to determine the types and proportions of flavor element additions (i.e., the ingredient addition formula). For example, the control system of the coffee machine 100 can store standard ingredient addition formulas for multiple common coffee beverages. When the user selects a certain coffee beverage, the control system automatically calls the corresponding formula. In addition, the ingredient addition formula can also be obtained based on the coffee raw material (coffee beans or coffee powder). Coffee beans from different origins and roasting degrees have different flavor characteristics. The coffee machine 100 can identify the type and information of the coffee raw material and determine the appropriate ingredient addition formula in combination with preset rules. For example, for lightly roasted coffee beans, since their flavor is relatively light, some flavor elements that can enhance the aroma and taste can be added; for darkly roasted coffee beans, since they are relatively bitter, some sweet flavor elements can be added to balance the taste.

[0095] Step S2: According to the ingredient addition formula, control the ingredient addition device 40 to add flavor elements with a preset ratio corresponding to the ingredient addition formula to the liquid supply pipeline.

[0096] In this step, when the ingredient addition device 40 receives an instruction sent by the control system, the release mechanism will put the corresponding flavor elements into the liquid supply pipeline according to the ratio and quantity required by the ingredient addition formula. During the dispensing process, the release mechanism will use a precise control device to ensure the accuracy of the dispensing amount to ensure that the brewed coffee has the expected taste and flavor.

[0097] In this embodiment, through this control method, various flavor elements can be added to the hot water for extracting coffee according to different requirements to prepare coffee with the most suitable taste and flavor to meet the customer's needs. By accurately adding flavor elements, the taste of the coffee is made more diverse, meeting consumers' pursuit of diverse flavors.

[0098] As Figure 3 shown, based on the first implementation manner of the control method of the above coffee machine 100, a second implementation manner of the control method of the coffee machine 100 provided by the present invention is proposed. In this implementation manner, the steps of S1 include:

[0099] Step S11: Obtain coffee flavor-related information, where the coffee flavor-related information includes the type of coffee raw material brewed by the brewing device 50 and / or the specified type of coffee beverage.

[0100] It can be understood that different coffee raw materials, such as coffee beans, usually have different flavor characteristics. For example, different coffee beans usually have different tastes, aromas, and caffeine contents. In order to maximize the extraction of the flavor characteristics of the corresponding coffee beans, it is necessary to add flavor elements with different ingredient addition formulas to the extraction hot water. In addition, different types of coffee beverages also have their own unique flavor requirements. There are various ways to obtain coffee flavor-related information. For the type of coffee beans, a coffee bean recognition device, such as an optical recognition sensor, an odor sensor, etc., can be set on the grinding device to identify the appearance, color, odor, etc. characteristics of the coffee beans, so as to determine the type of coffee beans. It can also be determined by the user's manual input, and the type of coffee beans used can be selected on the operation interface. For the specified type of coffee beverage, it can be determined by obtaining the user's order information.

[0101] Step S12: Confirm the ingredient addition formula according to the coffee flavor-related information.

[0102] In this step, according to the coffee risk-related information, the best ingredient addition formula can be calculated according to the preset rules and / or the information in the database.

[0103] In this embodiment, the method of determining the ingredient addition formula according to the coffee flavor-related information can make the added flavor elements better blend with the flavor of the coffee itself, maximize the flavor characteristics of the coffee raw materials, and improve the overall taste and quality of the coffee.

[0104] As Figure 4 shown, based on the second implementation manner of the control method of the above coffee machine 100, a third implementation manner of the control method of the coffee machine 100 provided by the present invention is proposed. In this implementation manner, before the step of S11, it includes:

[0105] Step S10: Create a database, which stores coffee flavor-related information and the corresponding ingredient addition formula.

[0106] In specific implementation, the database provides a basis for subsequent determination of the ingredient addition formula. The creation of the database can be completed by collecting a large amount of coffee experiment data, market research data, and the experience of professional baristas. For example, by conducting multiple brewing experiments on coffee beans from different origins and roasting degrees, recording the coffee taste and flavor evaluations under different flavor element addition ratios, and organizing and storing these data in the database. At the same time, the taste preference information of consumers for different coffee beverages can also be collected to further enrich the content of the database.

[0107] After the step of S2, it includes:

[0108] Step: S21 After the coffee brewing is completed, collect the evaluation information of the user on the coffee flavor.

[0109] In this step, the evaluation information of the user can be collected in various ways. One way is to set an evaluation button or a touch screen on the coffee machine 100. After the user tastes the coffee, the user can directly evaluate the flavor of the coffee on the coffee machine 100, such as giving a score, selecting the taste characteristics that they like or dislike, etc. Another way is to connect the coffee machine 100 with a mobile phone APP. The user can make a detailed evaluation of the coffee flavor through the mobile phone APP, including but not limited to descriptions of aspects such as taste, aroma, sweetness, bitterness, etc.

[0110] Step: S22 Update the database according to the evaluation information and the corresponding coffee flavor-related information, and optimize the ingredient addition formula.

[0111] In specific implementation, if many users feedback that the taste of a certain coffee is better after adding a certain flavor element, then the ingredient addition formula corresponding to this coffee can be adjusted accordingly in the database. During specific operation, the control system will analyze and process the collected evaluation information, extract useful information, such as that users generally think that the addition amount of a certain flavor element needs to be increased or decreased. Then, modify and optimize the corresponding ingredient addition formula in the database according to this information. By continuously collecting user evaluation information and updating the database, the coffee flavor produced by the coffee machine 100 can be made more in line with the taste requirements of consumers, and the satisfaction and loyalty of users can be improved.

[0112] As Figure 5 shown, based on the first embodiment of the control method of the above coffee machine 100, the fourth embodiment of the control method of the coffee machine 100 provided by the present invention is proposed. In this embodiment, the step of S1 includes:

[0113] Step S13: Obtain the required mineral supplement information.

[0114] In this step, the required mineral supplement information refers to the mineral components in the flavor elements that can supplement the user through coffee drinks according to the user's physical health condition. Specifically, the mineral supplement information can be related to the user's health needs, taste preferences, etc. For example, some users may need to supplement a certain amount of magnesium element due to physical reasons, then adding a flavor element containing magnesium element in the coffee can meet this requirement.

[0115] There are various ways to obtain the required mineral supplement information. One way is through manual input by the user. The user can enter their health status information, such as whether they are deficient in calcium, magnesium, etc., on the order operation interface. The control system of the coffee machine 100 analyzes and determines the required mineral supplement information based on the information entered by the user. Another way is by connecting to a health monitoring device. For example, the user can connect their health monitoring devices such as smart bracelets, smart watches, etc. to the coffee machine 100. The health monitoring device can monitor the user's body data in real time, such as heart rate, blood pressure, exercise data, etc. By analyzing these data, the user's health status and nutritional needs can be understood, so as to determine the required mineral supplement information. In addition, the required mineral supplement information can also be obtained based on the user's historical order records and taste preference analysis. If the user often orders coffee drinks with specific flavors and nutritional characteristics, the system can infer the user's taste preferences and potential nutritional needs.

[0116] Step S14: Confirm the ingredient addition formula according to the required mineral supplement information.

[0117] In specific implementation, for example, if the required mineral supplement information indicates a need to supplement calcium, then flavor elements containing calcium, such as calcium carbonate, calcium lactate, etc., can be selected, and their addition ratio in coffee can be determined. At the same time, the combination of these mineral elements with other flavor elements also needs to be considered to ensure that the taste and flavor of the coffee are not affected. The control system will calculate a suitable ingredient addition formula according to the preset rules and information in the database, in combination with the required mineral supplement information.

[0118] In this way, while consumers enjoy delicious coffee, they can also obtain necessary nutritional supplements. This method can not only meet the user's demand for coffee taste, but also provide personalized nutritional solutions for users, enhancing the health value of coffee.

[0119] Based on the fourth implementation manner of the control method of the coffee machine 100, in an optional embodiment,

[0120] The steps of S13 include:

[0121] Step: Conduct biometric identification on the user to obtain the user's identity information.

[0122] Biometric identification technology has high accuracy and security. Common biometric identification methods include fingerprint identification, facial recognition, and iris recognition, etc.

[0123] Step: Obtain the user's taste preferences, eating habit information, and / or health status information according to the identity information.

[0124] In this step, based on the obtained user identity information, the user's taste preferences, eating habits information, and / or health status information can be obtained. These information can be stored in the user's personal profile or obtained by connecting with health monitoring devices. For example, the user can fill in their taste preferences on the associated APP of the coffee machine 100, such as liking strong, light, sweet, bitter and other coffee flavors; record their eating habits, such as whether they often drink coffee and whether they eat with it. At the same time, connect with health monitoring devices such as smart bracelets and smart watches to obtain the user's exercise data, heart rate, blood pressure, sleep quality and other health indicators, so as to comprehensively understand the user's health status.

[0125] Step: Determine the required mineral supplement information related to the user based on the user's taste preferences, eating habits information, and / or health status information.

[0126] In this embodiment, by comprehensively considering the user's multi-faceted information, a more personalized and accurate mineral supplement plan can be provided for the user, making coffee not only a beverage but also a carrier to meet the user's health needs. This way of determining the required mineral supplement information according to the user's personal information can achieve personalized coffee production, better meet the user's needs, and enhance the user's consumption experience.

[0127] Based on the fourth implementation manner of the control method of the coffee machine 100, in another alternative embodiment,

[0128] The step of S13 includes:

[0129] Step: Obtain the order-taking geographical information.

[0130] In this step, the order-taking geographical information refers to the geographical location information where the user places an order.

[0131] It can be understood that the order-taking geographical information can reflect the characteristics of local water quality, eating habits, etc. The mineral content in the water quality of different regions is different. For example, the water quality in some regions is relatively hard, containing more calcium and magnesium ions; while the water quality in some regions is relatively soft, and the mineral content is relatively low. There are also differences in the eating habits of local residents. Some local residents like strong and bitter coffee flavors, while some local residents prefer light and sweet coffee. There are various ways to obtain the order-taking geographical information. The geographical location information where the coffee machine 100 is located can be obtained in real time through the built-in GPS positioning module of the coffee machine 100; the order-taking geographical information can also be determined through the address information input by the user when placing an order.

[0132] Specifically, the method for obtaining the order-taking geographical information includes:

[0133] Step: Obtain the identification code of the coffee machine 100.

[0134] Specifically, each coffee machine 100 has a unique identification code, which can be set by the manufacturer of the coffee machine 100 before leaving the factory. The control system can obtain the identification code information in the chip by reading the chip information built into the coffee machine 100.

[0135] Step: According to the identification code of the coffee machine 100, search for the order-taking geographical information corresponding to the identification code of the coffee machine 100 in the preset registration information database of the coffee machine 100.

[0136] In this step, the preset registration information database of the coffee machine 100 stores information such as the registration location of each coffee machine 100. This information database can be managed and maintained by the manufacturer or operator of the coffee machine 100. When the identification code of a coffee machine 100 is obtained, the system will quickly search and match in the information database to find the registration location information corresponding to the coffee machine 100. In this way, the order-taking geographical information can be accurately obtained, providing a reliable basis for determining the required mineral supplement information later.

[0137] Step: According to the order-taking geographical information, confirm the required mineral supplement information related to the geographical location corresponding to the order-taking geographical information.

[0138] In this embodiment, the local mineral deficiency condition is determined through the order-taking geographical information, so as to obtain the required mineral supplement information.

[0139] Such as Figure 6 As shown, based on the first implementation manner of the control method of the coffee machine 100, the fifth implementation manner of the control method of the coffee machine 100 provided by the present invention is proposed. In this implementation manner, after the step of S1 and before the step of S2, it includes:

[0140] Step S100: Obtain the real-time power of the pump body 20.

[0141] It can be understood that the real-time power of the pump body 20 reflects the flow rate and pressure of water in the liquid supply pipeline. In order to accurately obtain the real-time power of the pump body 20, a power sensor can be installed on the pump body 20. The power sensor can monitor parameters such as the current and voltage of the pump body 20 in real time, so as to determine the real-time power of the pump body 20. Connect the power sensor to the control system of the coffee machine 100 and transmit the power data to the control system in real time. For example, when the pump body 20 operates at a higher power, it indicates that the water flow rate in the liquid supply pipeline is faster and the pressure is greater; when the power of the pump body 20 is lower, the water flow rate and pressure are relatively smaller.

[0142] Step S200: Control the operation of the release mechanism according to the real-time power of the pump body 20, and adjust the speed at which the storage and release mechanism delivers the flavor elements in the preset ratio to the liquid supply pipeline, so that the water flowing to the brewing device 50 meets the target water quality standard.

[0143] Control the operation of the release mechanism according to the real-time power of the pump body 20, and adjust the speed at which the storage and release mechanism delivers the flavor elements in the preset ratio to the liquid supply pipeline, so that the water flowing to the brewing device 50 meets the target water quality standard. The target water quality standard includes requirements in aspects such as the pH value of water, mineral content, and flavor element ratio. When the real-time power of the pump body 20 increases, it indicates that the water flow rate has accelerated. At this time, the release mechanism needs to increase the speed of delivering the flavor elements to ensure that the ratio of the flavor elements to water conforms to the preset ratio. For example, if the preset ratio requires adding 5 grams of a certain flavor element per liter of water, when the power of the pump body 20 increases and the water flow rate accelerates, the release mechanism needs to deliver more flavor elements within the same time to ensure that the content of the flavor elements in the water finally entering the brewing device 50 reaches the standard. Conversely, when the power of the pump body 20 decreases and the water flow rate slows down, the release mechanism slows down the delivery speed. In this way, the amount and ratio of the delivered flavor elements can be accurately controlled.

[0144] In this embodiment, the release mechanism can adjust the delivery speed in various ways. For example, if the release mechanism uses a peristaltic pump to deliver the flavor elements, the delivery speed can be controlled by adjusting the rotation speed of the peristaltic pump. When it is necessary to increase the delivery speed, the control system increases the rotation speed of the peristaltic pump; when it is necessary to slow down the delivery speed, the rotation speed of the peristaltic pump is decreased. By this way of controlling the delivery speed of the flavor elements according to the real-time power of the pump body 20, the quality of coffee production can be better guaranteed, and the taste and flavor of the brewed coffee are more stable and consistent, meeting the needs of consumers for high-quality coffee. For example, the release mechanism can also use ultrasonic vibration to deliver the flavor elements. At this time, the delivery speed can be controlled by adjusting the vibration frequency of the ultrasonic vibration device.

[0145] The present invention also provides a coffee machine, as Figure 7 shown. The coffee machine includes at least one processor 701; and a memory 702 communicatively connected to the at least one processor 701. Wherein, the memory 702 stores instructions executable by the at least one processor 701, and the instructions are executed by the at least one processor 701 to enable the at least one processor 701 to execute the above-mentioned control method of the coffee machine.

[0146] Among them, the memory 702 and the processor 701 are connected in a bus manner. The bus can include any number of interconnected buses and bridges, which connect various circuits of one or more processors 701 and the memory 702 together. The bus can also connect various other circuits such as peripheral devices, voltage regulators, and power management circuits, etc. These are well known in the art, so they will not be further described herein. The bus interface provides an interface between the bus and the transceiver. The transceiver can be one element or multiple elements, such as multiple receivers and transmitters, and provides a unit for communicating with various other devices on the transmission medium. The data processed by the processor 701 is transmitted on the wireless medium through the antenna. Further, the antenna also receives data and transmits the data to the processor 701.

[0147] The processor 701 is responsible for managing the bus and general processing, and can also provide various functions, including timing, peripheral interface, voltage regulation, power management, and other control functions. The memory 702 can be used to store the data used by the processor 701 when performing operations.
