Description

Technical Field

[0001] This specification relates to the field of tea steaming technology, and in particular to a tea steaming control method based on capacitive liquid level detection. Background Technology

[0002] With the improvement of living standards, tea culture has gradually gained importance, leading to the emergence of equipment with steaming functions to make tea brewing more convenient. Existing technology CN 201810042773.4 discloses an automatic circulating tea brewing machine. When the amount of tea in the tea container falls below a preset level, the brewing mode is activated to begin the next infusion, thus achieving circulating tea brewing. During the circulating brewing process, fixed brewing parameters are used for each infusion. As the number of steaming cycles increases, the tea concentration gradually decreases, affecting the user's tea-drinking experience. Furthermore, users often find it difficult to accurately control the number of infusions and can only rely on subjective feelings after tasting to judge the tea concentration. If they feel the concentration is insufficient, they often choose to discard the tea and re-steam, resulting in water waste. This requires users to interrupt their tea-drinking process and wait for the steaming to resume, further reducing the user's tea-drinking experience.

[0003] Current tea steaming equipment typically employs simple low and high water level metal electrode detection mechanisms, which can only roughly determine the water level in the container and cannot achieve real-time monitoring of any water level within the container. During user operation, once the kettle is lifted to pour tea and then placed back down, it's impossible to accurately obtain the actual amount of water remaining in the kettle, and it's difficult to determine whether the tea leaves have been overused. This results in poor control over the tea's concentration, affecting the quality and taste of the tea.

[0004] In conclusion, current tea-steaming methods use fixed brewing parameters to steam the tea again after the user has finished drinking, ignoring the impact of the number of brewing cycles on the tea concentration, thus affecting the user's tea-drinking experience. Summary of the Invention

[0005] This specification provides one or more embodiments of a tea steaming control method based on capacitive liquid level detection, which is used to solve the following technical problem: In the current tea steaming method, after the user drinks the tea, the tea is steamed again using fixed brewing parameters, ignoring the influence of the number of brewing times on the tea concentration, thus affecting the user's tea drinking experience.

[0006] One or more embodiments of this specification employ the following technical solutions:

[0007] This specification provides one or more embodiments of a tea steaming control method based on capacitive liquid level detection, applied to the tea steaming function of a tea bar machine. The tea bar machine includes a liquid container, a water pump, and a water level detection area disposed on the side wall of the liquid container. The water level detection area is provided with a plurality of longitudinally distributed electrode plates. The method is characterized by comprising: performing a first brewing and steaming operation with preset first tea steaming parameters, followed by a heat preservation process; after the user performs at least one tea water dispensing operation, collecting the real-time remaining water level in the liquid container through the water level detection area; when the real-time remaining water level meets a preset tea brewing parameter adjustment threshold, adjusting the first tea steaming parameters according to the real-time remaining water level and the number of tea steaming operations corresponding to the first brewing and steaming operation, and using the adjusted second tea steaming parameters for tea steaming control.

[0008] Furthermore, before performing the first brewing and steaming operation with preset first steaming parameters, the method further includes: obtaining the user's first set water volume, and determining the required amount of tea based on the first set water volume; determining the first heating time corresponding to the first brewing and steaming operation according to the required amount of tea; and performing the first brewing and steaming of tea with the first set water volume using the first heating time.

[0009] Through the above technical solution, by obtaining the user's initial water volume setting, the user's tea drinking needs can be accurately matched. Whether the user prefers strong or weak tea, they can meet their needs by adjusting the water and tea leaves. The heating time is determined based on the user's set water volume and the calculated tea leaf requirement, which ensures that the taste of the steamed tea soup meets the user's expectations and improves user satisfaction. By determining the heating time based on the tea leaf requirement and the set water volume, the steaming process can be controlled more precisely, avoiding poor tea soup taste caused by excessive or insufficient heating time.

[0010] Furthermore, based on the real-time remaining water level and the pre-acquired number of steaming operations corresponding to the first brewing and steaming tea operation, the first steaming parameters are adjusted. Specifically, this includes: adjusting the first set water intake in the first steaming parameters based on the number of steaming operations corresponding to the first brewing and steaming tea operation; determining the second set water intake for the second brewing and steaming tea operation following the first brewing and steaming tea operation, wherein the second set water intake is lower than the first set water intake; determining the current water replenishment amount based on the real-time remaining water level and the second set water intake amount; and determining the adjusted second steaming parameters based on a second heating time that is higher than the first heating time in the first steaming tea parameters and the current water replenishment amount.

[0011] The above technical solution dynamically adjusts the steaming parameters based on the real-time remaining water level and the number of steaming cycles, ensuring that each steaming maintains a suitable tea concentration and flavor. As the number of steaming cycles increases, the amount of flavor compounds released from the tea leaves decreases. This change can be compensated for by reducing the water intake and extending the heating time, allowing users to enjoy consistent tea quality at different steaming stages. Precise control of water intake and heating time avoids tea that is too strong or too weak, improving the user's tea-drinking experience and reducing tea waste. Gradually reducing the water intake as the number of steaming cycles increases ensures tea concentration while minimizing unnecessary water waste. Adjusting the heating time makes the steaming process more efficient, reducing energy consumption.

[0012] Furthermore, based on the number of steaming operations corresponding to the first brewing and steaming tea operation, the first set water intake in the first steaming tea parameters is adjusted to determine the second set water intake for the second brewing and steaming tea operation following the first brewing and steaming tea operation. Specifically, this includes: obtaining the initial set water intake corresponding to the first brewing and steaming tea operation; determining the water intake adjustment ratio based on the number of steaming operations corresponding to the first brewing and steaming tea operation; and determining the second set water intake using the water intake adjustment ratio and the initial set water intake.

[0013] By dynamically adjusting the water volume based on the number of steaming cycles, a more personalized tea-brewing service can be provided to users. Different steaming cycles correspond to different water volumes, ensuring that each brew maintains a suitable concentration and taste, meeting individual user needs. The water volume required for each steaming cycle can be precisely calculated, and accurate control helps avoid overly strong or weak tea, improving the accuracy and stability of the brewing process. Dynamically adjusting the water volume ensures consistent tea quality for each brew, preventing changes in taste due to excessive or insufficient steeping time, thus enhancing the user's tea-drinking experience. Users do not need to manually adjust the water volume; the parameters are automatically adjusted based on the number of steaming cycles, reducing operational difficulty and complexity, and increasing user satisfaction.

[0014] Furthermore, after performing the first brewing and steaming operation with preset first steaming parameters, the method further includes: setting a steaming count task; under the trigger of a power-on signal, monitoring the brewing and steaming operation through the steaming count task; when the brewing and steaming operation is detected, accumulating the number of steaming times to determine the number of steaming times; and under the trigger of the end of the heat preservation operation and / or tea replacement reminder, resetting the count result of the steaming count task to zero.

[0015] By recording the number of steaming cycles, the usage of tea can be understood, avoiding overuse or waste. At the same time, the steaming parameters can be adjusted based on the remaining aroma and taste of the tea to make full use of the tea and ensure that each brew releases its best flavor.

[0016] Furthermore, the tea steaming is controlled using the adjusted second steaming parameters, specifically including: determining the current water replenishment amount and the second heating time in the second steaming parameters; determining the pumping control parameters of the water pump based on the current water replenishment amount, and controlling the water pump to perform pumping operation using the pumping control parameters; detecting the real-time water level in the liquid container through the water level detection area to determine whether the pre-acquired second set water inlet amount is met; when the real-time water level meets the second set water inlet amount, performing the tea brewing and steaming operation within the second heating time.

[0017] Through the above technical solution, the second steaming parameters, including the current water replenishment amount and the second heating time, are dynamically adjusted based on the number of steaming cycles and the real-time remaining water level. This achieves personalized steaming control, ensuring that each steaming maintains a suitable tea concentration and taste, meeting the user's individual needs. By accurately calculating the current water replenishment amount and determining the pumping control parameters (such as pumping rate and pumping time), precise control of the pumping process is achieved. This precise water replenishment method avoids water waste and ensures that the water level in the liquid container reaches the preset second set water intake amount. During the pumping process, the water level in the liquid container is monitored in real time through the water level detection area, ensuring the accuracy and timeliness of the pumping operation. When the real-time water level reaches the second set water intake amount, the pump automatically stops, preventing over- or under-pumping.

[0018] Furthermore, after controlling the water pump to perform the pumping operation, the method further includes: determining the current pumping duration of the water pump; determining the reference pumping volume of the water pump based on the current pumping duration and the pre-acquired water flow reference data of the water pump; and correcting the real-time water level when the water volume deviation between the reference pumping volume and the current replenishment volume meets the preset correction conditions.

[0019] By combining the pumping time and pump flow rate reference data to calculate the reference pumping volume and comparing it with the current replenishment volume calculated through liquid level, potential errors in the water level detection process can be detected in a timely manner and corrected accordingly, improving the accuracy of water volume judgment. When the water volume deviation meets the preset correction conditions, the real-time water level is automatically corrected, avoiding operational errors or system instability caused by water level detection errors. Through preset error water volume thresholds and correction conditions, it can automatically determine whether water level correction is needed and determine the correction factor based on the magnitude of the water volume deviation, improving the accuracy and efficiency of correction and reducing the cost and difficulty of manual intervention.

[0020] Furthermore, after controlling the steaming of tea with the adjusted second steaming parameters, the method further includes: determining the cumulative water replenishment amount in each brewing and steaming operation; determining the cumulative steeping water amount based on multiple cumulative water replenishment amounts and the initial set water amount corresponding to the first brewing and steaming operation; matching the corresponding steaming water amount threshold with the pre-obtained tea demand amount; sending a tea replacement reminder when the cumulative steeping water amount is not lower than the steaming water amount threshold; monitoring the remaining water level in the liquid container; and ending the heat preservation operation when the remaining water level is lower than the preset minimum water amount threshold.

[0021] By comparing the cumulative steeping water volume with the steaming water threshold, the system can intelligently determine the number of times tea leaves need to be steeped and whether they need to be replaced. This avoids a decline in taste due to over-steeping and ensures full utilization of the tea leaves, improving efficiency. When the cumulative steeping water volume reaches the steaming water threshold matching the current tea demand, an automatic tea replacement reminder is sent, eliminating the need for users to frequently monitor the steeping status and enhancing convenience and satisfaction. Real-time monitoring of the remaining water level in the container and termination of the heat preservation operation when the remaining water level falls below a preset minimum threshold effectively prevents overheating, damage, or safety hazards due to insufficient water. Precise control of water replenishment and heat preservation avoids unnecessary energy consumption. When the tea leaves are used to the point of needing replacement, timely water replenishment stops, and heat preservation ends when the water level is low, helping to reduce energy waste and achieve energy conservation.

[0022] Furthermore, the method also includes: obtaining the number of times of tea steaming corresponding to the first tea boiling and steaming operation and the initial set water volume corresponding to the first tea boiling and steaming operation; determining a threshold adjustment ratio based on the number of times of tea steaming, so as to determine the tea brewing parameter adjustment threshold corresponding to the first tea boiling and steaming operation based on the threshold adjustment ratio and the initial set water volume.

[0023] Through the above technical solution, the tea brewing parameter adjustment threshold can accurately determine when to add water and when to maintain the current water level for brewing and steaming tea based on the user's water intake frequency and real-time remaining water volume. This ensures that the concentration of each brew is maintained within the user's desired range, avoiding tea that is too strong or too weak, and improving the user's tea drinking experience. By setting the tea brewing parameter adjustment threshold, it can intelligently determine when to add water, thereby avoiding unnecessary waste. The introduction of the tea brewing parameter adjustment threshold enables the tea steaming equipment to automatically adjust the tea brewing parameters according to the user's tea drinking habits and water intake behavior, achieving intelligent control.

[0024] Furthermore, the method also includes: when the real-time remaining water level does not meet the preset tea brewing parameter adjustment threshold, executing a heat preservation process.

[0025] Through the above technical solution, after the first brewing and steaming operation, a heat preservation process is implemented. This heat preservation ensures that the tea soup maintains a suitable temperature for a period of time, preventing the tea soup from cooling down rapidly and affecting the taste. Under the heat preservation state, the aroma and flavor of the tea soup can be well preserved, allowing users to enjoy high-quality tea soup for a longer period of time. Users can drink the tea soup at any time after steaming without worrying about the tea soup cooling down, which improves the convenience of use. In addition, the appropriate heat preservation temperature can slow down the oxidation rate of substances in the tea soup, thereby extending the quality preservation time of the tea soup.

[0026] The above-described at least one technical solution adopted in the embodiments of this specification can achieve the following beneficial effects:

[0027] 1. Traditional tea steaming equipment uses fixed brewing parameters during the continuous brewing process, which causes the tea concentration to gradually decrease with the number of steamings, affecting the user's tea drinking experience. This technical solution monitors the remaining water level in the liquid container in real time and dynamically adjusts the steaming parameters according to the remaining water level and the number of steamings, ensuring that the appropriate tea concentration is obtained every time the tea is steamed, thereby significantly improving the user's tea drinking experience.

[0028] 2. In the existing technology, users often choose to discard tea and re-steam it because the tea concentration is insufficient. This not only wastes water resources, but also requires users to interrupt the tea drinking process and wait for the tea to be steamed again. This technical solution can effectively avoid the situation where the tea is discarded due to insufficient concentration by precisely controlling the tea steaming parameters and the remaining water level, thereby reducing the waste of water resources and ensuring the continuity of tea drinking for users.

[0029] 3. Traditional low and high water level metal electrode detection mechanisms can only roughly determine the water level in the container and cannot achieve real-time monitoring of any water level inside the container. This technical solution adopts capacitive liquid level detection technology, which can obtain the remaining water level in the liquid container in real time and accurately. When the user takes water for tea, the system compares the real-time remaining water level with the preset tea brewing parameter adjustment threshold to determine whether the tea steaming parameters need to be adjusted. This makes the tea steaming process more flexible and precise, and can be dynamically adjusted according to actual needs. Attached Figure Description

Obviously, the drawings described below are only some embodiments recorded in this specification. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. In the drawings:

[0032] Figure 2 This is a schematic diagram of the electrode distribution in a water level detection area provided in an embodiment of this specification. Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0034] This specification provides a tea steaming control method based on capacitive liquid level detection. It should be noted that the execution subject in this specification embodiment can be a server or any device with data processing capabilities. Figure 1 This is a flowchart illustrating a tea steaming control method based on capacitive liquid level detection, as provided in the embodiments of this specification. Figure 1 As shown, the main steps include the following:

[0035] Step S101: After performing the first brewing and steaming operation with the preset first tea steaming parameters, the heat preservation process is executed.

[0036] In one embodiment of this specification, the method described herein is applied to the tea-steaming function of a tea bar machine. The tea bar machine includes a liquid container, a water pump, and a water level detection area disposed on the side wall of the liquid container. The water level detection area is provided with a plurality of longitudinally distributed electrode plates. Figure 2 This is a schematic diagram of the electrode distribution in a water level detection area provided in an embodiment of this specification. The kettle in the tea bar machine is equipped with electrodes as shown in the diagram. Figure 2 The capacitance detection plate shown includes multiple staggered electrode plates. A certain space is reserved between two adjacent electrode plates to serve as a judgment node for the water level line. This ensures that only one electrode plate in a single row can detect a capacitance change at any given time, improving detection accuracy. The staggered arrangement of the electrode plates effectively avoids direct interference between adjacent electrode plates, and the reserved space between adjacent electrode plates serves as a judgment node for the water level line. This ensures that only one electrode plate in a single row can detect a capacitance change at any given time, avoiding false judgments caused by multiple electrode plates simultaneously detecting capacitance changes, thus improving detection accuracy.

[0037] like Figure 2 As shown, 11 self-capacitance electrode plates are set in the water level detection area, and each self-capacitance electrode plate corresponds to a different detection liquid level. For example, the self-capacitor G18 can detect liquid levels in the range of 400–500 ml, the self-capacitor G29 in the range of 400–600 ml, the self-capacitors G23 and G24 in the range of 500–700 ml, the self-capacitor G25 in the range of 600–800 ml, the self-capacitor G22 in the range of 700–900 ml, the self-capacitor G26 in the range of 800–1000 ml, the self-capacitor G21 in the range of 900–1100 ml, the self-capacitor G27 in the range of 1000–1200 ml, the self-capacitor G20 in the range of 1100–1300 ml, the self-capacitor G28 in the range of 1200–1400 ml, and the self-capacitor G19 in the range of 1300–1500 ml. Through, as... Figure 2 The staggered design shown has a corresponding detection electrode for every 100ml of liquid level, allowing for the detection of multiple liquid levels within the range of 500-1400ml. For example, an 800ml liquid level can be detected using G25. When water reaches or nearly reaches G25, the detection level corresponding to G25 is triggered, thus achieving the purpose of detecting an 800ml liquid level. In addition to G25, the 800ml level can also be detected by utilizing the capacitance characteristic corresponding to the point where water just touches G26.

[0038] Before performing the first brewing and steaming operation with preset first steaming parameters, the method further includes: obtaining the user's first set water volume, and determining the required amount of tea based on the first set water volume; determining the first heating time corresponding to the first brewing and steaming operation according to the required amount of tea; and performing the first brewing and steaming of the tea with the first set water volume using the first heating time.

[0039] In one embodiment of this specification, the first brewing of tea is performed upon manual triggering by the user. The user sets the required water volume for brewing according to their preferences and needs, thus obtaining the user's initial water volume. It should be noted that this initial water volume refers to the water required for the first brewing process and should be within the operating capacity range of the liquid container. Multiple water volume trigger buttons within the operating capacity range can be set on the tea machine. When the user needs to brew tea, they can select the corresponding water volume by clicking the trigger button. Generally, the water volume for the first brew is set within the capacity range, for example, the maximum allowable water volume for a single pot. Since different water volumes correspond to different tea types and weights, the user selects the corresponding tea type when setting the initial water volume for the first brewing process.

[0040] After determining the initial water volume, the required tea weight for this tea type is determined according to the pre-set correspondence between the tea quantity and the initial brew volume for that tea type. It should be noted that this correspondence between the tea quantity and the initial brew volume can be obtained through experimental data. For different types of tea, brewing and steaming tests can be conducted by controlling variables. At a given tea weight, different brewing water volumes are tested to determine the corresponding tea concentration. The highest tea concentration within the range acceptable to the general public is used as the initial brew volume for that tea weight. Besides the above method, users can also choose their preferred tea concentration range, and the highest tea concentration within that range is used to match the initial brew volume. Following the above testing methods, the correspondence between the tea quantity and the initial brew volume for different tea types can be obtained.

[0041] Based on the determined tea quantity and the initial water volume, the first heating time for the initial tea brewing and steaming operation is determined. First, a data table can be created containing tea type, tea weight, corresponding water volume, and recommended heating time. This table can be built based on experimental data, user feedback, or suggestions from professional tea masters. The corresponding recommended basic heating time is then searched in the database. If the user selects a flavor preference (e.g., strong, medium, weak), the basic heating time is adjusted according to this preference to obtain the first heating time. For example, strong tea may require a longer heating time, while weak tea may require a shorter heating time. Using this first heating time, the tea with the initial water volume is then brewed and steamed for the first time.

[0042] Through the above technical solution, by obtaining the user's initial water volume setting, the user's tea drinking needs can be accurately matched. Whether the user prefers strong or weak tea, they can meet their needs by adjusting the water and tea leaves. The heating time is determined based on the user's set water volume and the calculated tea leaf requirement, which ensures that the taste of the steamed tea soup meets the user's expectations and improves user satisfaction. By determining the heating time based on the tea leaf requirement and the set water volume, the steaming process can be controlled more precisely, avoiding poor tea soup taste caused by excessive or insufficient heating time.

[0043] In one embodiment of this specification, after performing the first brewing and steaming operation with preset first steaming parameters, a heat preservation process is executed. The first brewing and steaming operation here can be the initial brewing and steaming of tea, or a subsequent brewing and steaming operation following the initial brewing and steaming.

[0044] After the initial brewing and steaming process, a heat preservation process is implemented. This ensures that the tea soup maintains a suitable temperature for a period of time, preventing it from cooling down rapidly and affecting the taste. Under heat preservation conditions, the aroma and flavor of the tea soup are better preserved, allowing users to enjoy high-quality tea soup for a longer period of time. Users can drink the tea soup at any time after steaming without worrying about it cooling down, which improves the convenience of use. In addition, the appropriate heat preservation temperature can slow down the oxidation rate of substances in the tea soup, thereby extending the quality preservation time of the tea soup.

[0045] After performing the first brewing and steaming operation with preset first steaming parameters, the method further includes: setting a steaming count task; under the trigger of a power-on signal, monitoring the brewing and steaming operation through the steaming count task; when the brewing and steaming operation is detected, accumulating the number of steaming times to determine the number of steaming times; and under the trigger of the end of the heat preservation operation and / or tea replacement reminder, resetting the count result of the steaming count task to zero.

[0046] In one embodiment of this specification, a tea-steaming count task is set up and activated upon power-on. This task monitors each tea-brewing and steaming operation and accumulates the count of steaming times. When the tea-steaming process ends and a tea-replacement reminder is triggered, the count result is reset to zero for the next round of counting. First, a tea-steaming count task is set up in the tea bar machine's control system to monitor the progress of the tea-brewing and steaming operation. When the tea bar machine is powered on, the tea-steaming count task is activated; that is, each time power is connected, the count task begins preparing to record the number of tea steaming times. The tea-steaming count task can determine whether the tea-brewing and steaming operation has commenced by monitoring the working status of key components such as the heating element and temperature sensor of the tea steamer, as well as by the user triggering the tea-brewing function. After the user triggers the tea-brewing function, once the heating element is detected to be working and the temperature reaches the preset tea-brewing temperature range, a tea-brewing and steaming operation is considered to have begun. Each time the start of a tea-brewing and steaming operation is detected, the tea-steaming count task increments by one, recording the number of tea steaming operations in real time. The tea-steaming count will be reset to zero in two situations: when the keep-warm operation ends and when a tea-replacement reminder is triggered. Generally, a keep-warm operation is performed after each tea brewing session. The end of the keep-warm operation indicates the end of the user's tea-steaming process, and the count will be reset to zero. Additionally, a tea-replacement reminder will be triggered when it is detected that the tea has been used a certain number of times or for a certain period of time and needs to be replaced. At this time, the user can choose whether to replace the tea immediately, and the count will also be reset to zero after confirmation.

[0047] By recording the number of steaming cycles, the usage of tea can be understood, avoiding overuse or waste. At the same time, the steaming parameters can be adjusted based on the remaining aroma and taste of the tea to make full use of the tea and ensure that each brew releases its best flavor.

[0048] Step S102: After the user performs at least one tea-drinking operation, the real-time remaining water level in the liquid container is collected through the water level detection area.

[0049] In one embodiment of this specification, after a user performs at least one tea-drinking operation, the real-time remaining water level in the liquid container is collected using electrode plates in the water level detection area. If the user lifts the teapot to drink water and then places it back down, liquid level fluctuations occur during the placement process. The real-time remaining water level is detected by utilizing the effect of these fluctuations on the capacitance of the electrode plates. If the tea-drinking process involves direct water dispensing, the remaining water level can be detected by utilizing the effect of the water level drop during dispensing on the capacitance of the electrode plates.

[0050] The above technical solution allows for real-time monitoring of the remaining water level, enabling timely replenishment when the water level is too low, preventing interruptions in tea supply and enhancing the user's tea-drinking experience. It also allows for automatic adjustment of parameters such as water dispensing and heating based on the real-time water level, achieving automated management and improving efficiency. Furthermore, monitoring the remaining water level after a user dispenses tea can reflect their drinking water consumption to some extent. Real-time water level monitoring allows for more precise control of the heating and dispensing process, reducing unnecessary energy consumption and achieving energy-saving effects.

[0051] Step S103: When the real-time remaining water level meets the preset tea brewing parameter adjustment threshold, the first tea steaming parameter is adjusted according to the real-time remaining water level and the number of tea steaming operations corresponding to the first brewing and steaming operation obtained in advance, and the tea steaming is controlled by the adjusted second tea steaming parameter.

[0052] In one embodiment of this specification, after a user takes tea, a real-time remaining water level is recorded after each water intake. As the number of water intakes increases, the real-time remaining water level in the container gradually decreases, meaning the remaining water volume gradually decreases. When the remaining water volume meets a preset tea brewing parameter adjustment threshold (i.e., is less than the threshold), it indicates that the user has taken a large amount of water, and the remaining amount in the container is small, requiring water replenishment before the tea brewing process is repeated. When the remaining water volume does not meet the preset tea brewing parameter adjustment threshold (i.e., is greater than the threshold), it is considered that the user has consumed a small amount of tea, and no further water replenishment is needed. Therefore, when the real-time remaining water level does not meet the preset tea brewing parameter adjustment threshold, a heat preservation process is initiated.

[0053] In one embodiment of this specification, different teas have different requirements for water volume and steaming parameters. As the number of steaming cycles increases and the remaining water decreases, the aroma and taste of the tea may change. When the remaining water volume meets the preset tea brewing parameter adjustment threshold, the first steaming parameters are adjusted based on the real-time remaining water level and the number of steaming cycles corresponding to the first brewing and steaming operation. The adjusted second steaming parameters are then used for tea brewing control. By adjusting the steaming parameters, the current state of the tea can be better adapted, ensuring that each brew achieves the best taste. When the remaining water volume is low, continuing to use the same steaming parameters may result in excessively high tea concentration, affecting the taste. By adjusting the steaming parameters, such as lowering the temperature or shortening the steaming time, the tea concentration can be reduced, making it more suitable.

[0054] The method further includes: obtaining the number of times the tea is steamed corresponding to the first brewing and steaming operation and the initial set water volume corresponding to the first brewing and steaming operation; determining a threshold adjustment ratio based on the number of times the tea is steamed, and determining the tea brewing parameter adjustment threshold corresponding to the first brewing and steaming operation based on the threshold adjustment ratio and the initial set water volume.

[0055] In one embodiment of this specification, the determination of the tea brewing parameter adjustment threshold is related to the initial water volume set for the first brewing and steaming operation. The initial water volume set for the first brewing and steaming operation can be assumed to be the rated water volume of the liquid container. Furthermore, since the number of steaming operations affects the setting of subsequent tea brewing parameters, the tea concentration gradually decreases with the same water volume as the number of steaming operations increases. In other words, the more times the tea is steamed, the less water is needed for subsequent brewing and steaming operations. Therefore, the number of steaming operations corresponding to the first brewing and steaming operation and the initial water volume set for the first brewing and steaming operation are obtained to determine the tea brewing parameter adjustment threshold corresponding to the first brewing and steaming operation.

[0056] First, determine the threshold adjustment ratio based on the number of steaming operations, using the formula [1-(x-1) / n]*(1 / 2), where x is the number of steaming operations corresponding to the first brewing operation, and n is the preset adjustment step size. This adjustment step size is related to the number of infusions corresponding to the required tea quantity; that is, the more infusions, the larger the corresponding adjustment step size. The number of infusions can be directly set as the adjustment step size. For example, if the tea concentration has decreased to the drinking concentration threshold after 4 infusions with the initial water volume, the adjustment step size can be set to 4. After determining the threshold adjustment ratio in the above way, the tea brewing parameter adjustment threshold corresponding to the first brewing operation is determined by multiplying the threshold adjustment ratio by the initial water volume. For example, when the number of steaming operations is 1 (the first brew), the corresponding tea brewing parameter adjustment threshold is 1 / 2 of the initial water volume; when the number of steaming operations is 2, the corresponding tea brewing parameter adjustment threshold is 3 / 8 of the initial water volume.

[0057] Through the above technical solution, the tea brewing parameter adjustment threshold can accurately determine when to add water and when to maintain the current water level for brewing and steaming tea based on the user's water intake frequency and real-time remaining water volume. This ensures that the concentration of each brew is maintained within the user's desired range, avoiding tea that is too strong or too weak, and improving the user's tea drinking experience. By setting the tea brewing parameter adjustment threshold, it can intelligently determine when to add water, thereby avoiding unnecessary waste. The introduction of the tea brewing parameter adjustment threshold enables the tea steaming equipment to automatically adjust the tea brewing parameters according to the user's tea drinking habits and water intake behavior, achieving intelligent control.

[0058] Based on the real-time remaining water level and the number of steaming operations corresponding to the first brewing and steaming operation, the first steaming parameters are adjusted. Specifically, this includes: adjusting the first set water intake in the first steaming parameters based on the number of steaming operations corresponding to the first brewing and steaming operation; determining the second set water intake for the second brewing and steaming operation following the first brewing and steaming operation, wherein the second set water intake is lower than the first set water intake; determining the current water replenishment amount based on the real-time remaining water level and the second set water intake amount; and determining the adjusted second steaming parameters based on a second heating time that is higher than the first heating time in the first steaming parameters and the current water replenishment amount.

[0059] In one embodiment of this specification, if the real-time remaining water level is less than the tea brewing parameter adjustment threshold, the first tea steaming parameter is adjusted based on the real-time remaining water level and the number of steaming operations corresponding to the first brewing and steaming operation. The number of steaming operations corresponding to the first brewing and steaming operation reflects the current number of times the tea leaves are steamed. The higher the number of steaming operations, the lower the tea concentration with the same amount of water. To ensure the tea concentration when the user drinks the tea, the water intake for the second brewing and steaming operation, which follows the first brewing and steaming operation, is set to a second set water intake, which is lower than the first set water intake in the first tea steaming parameter, based on the number of steaming operations corresponding to the first brewing and steaming operation. After determining the second set water intake for the second brewing and steaming operation, the current water replenishment is determined by the difference between the second set water intake and the real-time remaining water level. That is, the amount of water that needs to be replenished to ensure the execution of the second brewing and steaming operation. As the number of steaming operations increases, the set water intake gradually decreases, while the steaming time is extended to a second heating time, which is higher than the first heating time in the first tea steaming parameter, and the current water replenishment, to determine the adjusted second tea steaming parameter.

[0060] It should be noted that the second heating time here can be determined based on the initial heating time corresponding to the first brewing and steaming operation and the number of steaming operations corresponding to the first brewing and steaming operation. The specific setting method is as follows: First, determine the preset adjustment step size n, and obtain the second heating time according to the formula [1+(x-1) / n]*T0, where x is the number of steaming operations corresponding to the first brewing and steaming operation, n is the preset adjustment step size, and the setting of n here is the same as the setting of the adjustment step size in the threshold adjustment ratio, and T0 is the initial heating time corresponding to the first brewing and steaming operation.

[0061] The above technical solution dynamically adjusts the steaming parameters based on the real-time remaining water level and the number of steaming cycles, ensuring that each steaming maintains a suitable tea concentration and flavor. As the number of steaming cycles increases, the amount of flavor compounds released from the tea leaves decreases. This change can be compensated for by reducing the water intake and extending the heating time, allowing users to enjoy consistent tea quality at different steaming stages. Precise control of water intake and heating time avoids tea that is too strong or too weak, improving the user's tea-drinking experience and reducing tea waste. Gradually reducing the water intake as the number of steaming cycles increases ensures tea concentration while minimizing unnecessary water waste. Adjusting the heating time makes the steaming process more efficient, reducing energy consumption.

[0062] Based on the number of steaming operations corresponding to the first brewing and steaming tea operation, the first set water intake in the first steaming tea parameter is adjusted to determine the second set water intake for the second brewing and steaming tea operation following the first brewing and steaming tea operation. Specifically, this includes: obtaining the initial set water intake corresponding to the first brewing and steaming tea operation; determining the water intake adjustment ratio based on the number of steaming operations corresponding to the first brewing and steaming tea operation; and determining the second set water intake based on the water intake adjustment ratio and the initial set water intake.

[0063] In one embodiment of this specification, when adjusting the first set water intake based on the number of tea steaming operations, the initial set water volume corresponding to the first tea steaming operation is first obtained. Based on the initial set water volume, the second set water intake is obtained through a water volume adjustment ratio. The second set water intake is calculated according to the formula [1-(x-1) / n]*V1, where x is the number of tea steaming operations corresponding to the first tea steaming operation, n is a preset adjustment step size (the setting of n here is the same as the setting of the adjustment step size in the threshold adjustment ratio), and V1 is the initial set water volume corresponding to the first tea steaming operation.

[0064] By dynamically adjusting the water volume based on the number of steaming cycles, a more personalized tea-brewing service can be provided. Different steaming cycles correspond to different water volumes, ensuring that each brew maintains a suitable concentration and taste, meeting individual user needs. Using pre-set formulas and parameters (such as the adjustment step size n and the initial water volume V1), the required water volume for each steaming cycle can be precisely calculated. This precise control helps avoid overly strong or weak tea, improving the accuracy and stability of the brewing process. Dynamically adjusting the water volume ensures consistent tea quality for each brew, preventing changes in taste due to excessive or insufficient steeping time, thus enhancing the user's tea-drinking experience. Users do not need to manually adjust the water volume; the parameters are automatically adjusted based on the number of steaming cycles, reducing operational difficulty and complexity, and increasing user satisfaction.

[0065] The tea steaming is controlled using the adjusted second steaming parameters, specifically including: determining the current water replenishment amount and the second heating time in the second steaming parameters; determining the pumping control parameters of the water pump based on the current water replenishment amount, and controlling the water pump to perform the pumping operation using the pumping control parameters; detecting the real-time water level in the liquid container through the water level detection area to determine whether it meets the pre-acquired second set water level; when the real-time water level meets the second set water level, performing the tea brewing and steaming operation within the second heating time.

[0066] In one embodiment of this specification, the current water replenishment amount and the second heating time in the second tea steaming parameters are determined. The current water replenishment amount is the amount of water that the water pump needs to extract, and based on this, water pumping control parameters, such as pumping rate and pumping time, are determined. The water pumping control parameters are sent to the water pump to control it to perform the pumping operation, extracting the required amount of water from the water source into the liquid container. During the pumping process, the water level in the liquid container is monitored in real time through a water level detection area. When the real-time water level reaches the second set water inlet amount, the pumping operation is considered complete, and the water pump stops working. After confirming that the water volume in the liquid container has reached the second set water inlet amount, the heating device is started to begin the heating process. The water in the liquid container is continuously heated during the second heating time, allowing the tea leaves to fully release their flavor substances, thus completing the tea brewing and steaming operation.

[0067] Through the above technical solution, the second steaming parameters, including the current water replenishment amount and the second heating time, are dynamically adjusted based on the number of steaming cycles and the real-time remaining water level. This achieves personalized steaming control, ensuring that each steaming maintains a suitable tea concentration and taste, meeting the user's individual needs. By accurately calculating the current water replenishment amount and determining the pumping control parameters (such as pumping rate and pumping time), precise control of the pumping process is achieved. This precise water replenishment method avoids water waste and ensures that the water level in the liquid container reaches the preset second set water intake amount. During the pumping process, the water level in the liquid container is monitored in real time through the water level detection area, ensuring the accuracy and timeliness of the pumping operation. When the real-time water level reaches the second set water intake amount, the pump automatically stops, preventing over- or under-pumping.

[0068] After controlling the water pump to perform the pumping operation, the method further includes: determining the current pumping time of the water pump; determining the reference pumping volume of the water pump based on the current pumping time and the pre-acquired water flow reference data of the water pump; and correcting the real-time water level when the water volume deviation between the reference pumping volume and the current replenishment volume meets the preset correction conditions.

[0069] In one embodiment of this specification, errors may exist in the detection of real-time water level during the pumping process and the real-time remaining water level after the kettle is returned. To ensure the accuracy of water volume judgment, corrections can be made by incorporating the actual water addition time during the pumping process. The pumping time from the start of pumping to the current moment is recorded; this pumping time is dynamically changing and increases as the pumping process continues. Reference data for the pump flow rate is pre-acquired or stored, representing the amount of water the pump can extract per unit time. This reference data can be the average flow rate of a normal pump. Based on the product of the current pumping time and the reference flow rate data, the actual amount of water extracted by the pump within the current pumping time is calculated, i.e., the reference pumping volume. The reference pumping volume corresponding to the actual pumping volume is compared with the liquid level to calculate the current replenishment volume. If the water volume deviation between these two values ​​meets a preset correction condition, it indicates that there may be a problem with the water level detection process, and the real-time water level needs to be corrected.

[0070] In one embodiment of this specification, a preset allowable error water volume threshold is defined. If the water volume deviation between the reference pumping volume and the current replenishment volume is within 10% of the error water volume threshold, the water level detection is considered accurate and requires no correction. If the water volume deviation between the reference pumping volume and the current replenishment volume is within 10% to 30% of the error water volume threshold, the correction condition is met. When the correction condition is met, a correction factor is determined by the ratio of the water volume deviation to the error water volume threshold. The detected real-time water level is corrected using the correction factor. The real-time water level here can be the real-time pumping water level during the pumping process or the real-time remaining water level after the kettle is returned. In correcting the detected real-time water level, the correction value is determined by multiplying the correction factor and the real-time water level. If the water volume deviation is positive, meaning the reference pumping volume corresponding to the actual pumping volume is greater than the current replenishment volume calculated from the liquid level, the real-time water level detection value is considered low. The corrected water level value is then determined by the sum of the real-time water level detection value and the correction value. Conversely, if the water volume deviation is negative, meaning the reference pumping volume corresponding to the actual pumping volume is less than the current replenishment volume calculated from the liquid level, it indicates that the real-time water level detection value is too high. The corrected water level value is then determined by the difference between the real-time water level detection value and the correction value. When the water volume deviation between the reference pumping volume and the current replenishment volume exceeds 30% of the error water volume threshold multiple times consecutively, the number of deviation anomalies is counted. When the number of deviation anomalies exceeds the preset warning threshold, an anomaly alert is sent.

[0071] By combining the pumping time and pump flow rate reference data to calculate the reference pumping volume and comparing it with the current replenishment volume calculated through liquid level, potential errors in the water level detection process can be detected in a timely manner and corrected accordingly, improving the accuracy of water volume judgment. When the water volume deviation meets the preset correction conditions, the real-time water level is automatically corrected, avoiding operational errors or system instability caused by water level detection errors. Through preset error water volume thresholds and correction conditions, the system can automatically determine whether water level correction is needed and determine the correction factor based on the magnitude of the water volume deviation, improving the accuracy and efficiency of correction and reducing the cost and difficulty of manual intervention. When the water volume deviation exceeds a large proportion of the preset error water volume threshold multiple times consecutively, the system will count the number of abnormal deviations and send an abnormality alert when the number exceeds the warning threshold, which helps to detect and deal with potential problems in a timely manner and avoid the escalation of faults or more serious consequences.

[0072] After controlling the steaming of tea with the adjusted second steaming parameters, the method further includes: determining the cumulative water replenishment amount in each brewing and steaming operation; determining the cumulative steeping water amount based on multiple cumulative water replenishment amounts and the initial set water amount corresponding to the first brewing and steaming operation; matching the corresponding steaming water amount threshold with the pre-obtained tea demand amount; sending a tea replacement reminder when the cumulative steeping water amount is not lower than the steaming water amount threshold; and monitoring the remaining water level in the liquid container; ending the heat preservation operation when the remaining water level is lower than the preset minimum water amount threshold.

[0073] In one embodiment of this specification, the amount of water added during each brewing and steaming operation is recorded and accumulated. This accumulated water amount is dynamically changed and increases with each operation. Based on the accumulated water amount from multiple brewing and steaming operations, and the initial water amount set for the first brewing and steaming operation (i.e., the water amount at the first operation), the cumulative steeping water amount is calculated, representing the total amount of water in the liquid container from the first operation to the current moment. Pre-stored tea-steeping water amount thresholds corresponding to different tea-related requirements are also included. These thresholds are determined based on factors such as the type and quality of the tea, and the number of infusions, representing the maximum amount of tea water that can be steamed under a certain tea-related requirement. When the accumulated steeping water amount reaches the tea-steeping water amount threshold matching the current tea-related requirement, a tea replacement reminder is sent, prompting the user to replace the tea with new tea. When the accumulated water volume reaches the threshold for steaming tea that matches the current tea's required volume, the system assumes the tea has been used for an extended period and prompts the user to replace it. Furthermore, since the set steaming water threshold has been exceeded, no more water will be added after the user removes the kettle and places it back in the container. The system also monitors the remaining water level in the container in real time. When the remaining water level falls below a preset minimum water level threshold, the heat preservation operation will terminate to prevent equipment damage or safety hazards due to insufficient water.

[0074] By comparing the cumulative steeping water volume with the steaming water threshold, the system can intelligently determine the number of times tea leaves need to be steeped and whether they need to be replaced. This avoids a decline in taste due to over-steeping and ensures full utilization of the tea leaves, improving efficiency. When the cumulative steeping water volume reaches the steaming water threshold matching the current tea demand, an automatic tea replacement reminder is sent, eliminating the need for users to frequently monitor the steeping status and enhancing convenience and satisfaction. Real-time monitoring of the remaining water level in the container and termination of the heat preservation operation when the remaining water level falls below a preset minimum threshold effectively prevents overheating, damage, or safety hazards due to insufficient water. Precise control of water replenishment and heat preservation avoids unnecessary energy consumption. When the tea leaves are used to the point of needing replacement, timely water replenishment stops, and heat preservation ends when the water level is low, helping to reduce energy waste and achieve energy conservation.

[0075] The technical solutions described in this specification address the issue that traditional tea steaming equipment uses fixed brewing parameters during the continuous brewing process, leading to a gradual decrease in tea concentration with each steaming cycle, thus affecting the user's tea-drinking experience. This technical solution, by real-time monitoring of the remaining water level in the liquid container and dynamically adjusting the steaming parameters based on the remaining water level and the number of steaming cycles, ensures that each steaming yields a suitable tea concentration, significantly improving the user's tea-drinking experience. In existing technologies, users often discard tea and restart the steaming process due to insufficient tea concentration, which not only wastes water but also requires users to interrupt their tea-drinking process and wait for the steaming to resume. This technical solution precisely controls the steaming parameters and the remaining water... This technology effectively prevents tea from being discarded due to insufficient concentration, thus reducing water waste and ensuring the continuity of tea drinking for users. Traditional low and high water level metal electrode detection mechanisms can only roughly determine the water level in the container and cannot achieve real-time monitoring of arbitrary water levels inside the container. This technical solution adopts capacitive liquid level detection technology, which can obtain the remaining water level in the liquid container in real time and accurately. When the user takes water for tea, the system compares the real-time remaining water level with the preset tea brewing parameter adjustment threshold to determine whether the tea steaming parameters need to be adjusted. This makes the tea steaming process more flexible and precise, and can be dynamically adjusted according to actual needs.
