Description

Technical Field

[0001] The present specification relates to the technical field of steaming tea, and in particular to a steaming tea control method based on capacitive liquid level detection. Background Art

[0002] With the improvement of living standards, the culture of drinking tea has gradually been taken seriously by people, and correspondingly, equipment with the function of steaming tea has appeared to make tea making more convenient. The prior art CN 201810042773.4 discloses an automatic circulation tea brewing machine. When the amount of tea in the tea container is lower than the preset amount of water, the tea brewing mode is started and the next brewing is started to realize the circulation tea brewing. In the process of circulating tea brewing, fixed tea brewing parameters are used for each tea brewing operation. As the number of steaming tea increases, the concentration of tea gradually decreases, affecting the user's tea drinking experience. And when the user actually performs the steaming tea operation, it is often difficult to accurately grasp the number of times the tea is brewed, and can only rely on the subjective feeling after tasting to judge the concentration of the tea. Once the concentration is insufficient, the user often chooses to abandon the tea and steam the tea again, which will cause the problem of water resource waste, requiring the user to interrupt the tea drinking process and wait for the steaming tea again, further reducing the user's tea drinking experience.

[0003] Current tea steaming equipment usually uses a simple low water level and high water level metal electrode detection mechanism, which can only roughly determine the water level status in the container, but cannot achieve real-time monitoring of any water level inside the container. During user use, once the kettle is lifted to pour tea and put back, it is impossible to accurately obtain the actual amount of water remaining in the kettle, and it is difficult to determine whether the tea has been overused, which has a poor effect on controlling the concentration of tea, affecting the quality and taste of the tea.

[0004] In summary, in the current tea steaming method, after the user drinks the tea from the pot, fixed tea brewing parameters are used for re-steaming, ignoring the effect of the number of tea brewing times on the tea concentration, which in turn affects the user's tea drinking experience. Summary of the invention

[0005] One or more embodiments of the present specification provide 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 picks up the pot to drink tea, fixed tea brewing parameters are used for re-steaming, ignoring the effect of the number of times the tea leaves are brewed on the concentration of the tea, which in turn affects the user's tea drinking experience.

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

[0007] One or more embodiments of the present specification provide a tea steaming control method based on capacitive liquid level detection, which is applied to the tea steaming function of a tea bar machine, wherein the tea bar machine includes a liquid container, a water pump and a water level detection area arranged on the side wall of the liquid container, wherein a plurality of electrode sheets distributed longitudinally are arranged in the water level detection area, and the method comprises: after performing a first boiling and steaming tea operation with a preset first tea steaming parameter, performing a heat preservation process; when a user performs at least one tea water extraction 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 parameter according to the real-time remaining water level and the number of tea steaming times corresponding to the first boiling and steaming tea operation obtained in advance, and performing tea steaming control with the adjusted second tea steaming parameter.

[0008] Furthermore, before performing the first boiling and steaming tea operation with the preset first tea steaming parameter, the method also includes: obtaining a first set water volume of the user to determine a tea demand based on the first set water volume; determining a first heating time corresponding to the first boiling and steaming tea operation according to the tea demand; and boiling and steaming the tea leaves with the first set water volume for the first time with the first heating time.

[0009] Through the above technical scheme, by obtaining the user's first set water volume, the user's tea drinking needs can be accurately matched. No matter the user likes strong tea or light tea, the needs can be met by adjusting the water volume and the amount of tea leaves. The heating time is determined according to the water volume set by the user and the calculated tea demand, which can ensure that the taste of the steamed tea meets the user's expectations and improve the user's satisfaction. By determining the heating time based on the tea demand and the set water volume, the tea steaming process can be controlled more accurately to avoid poor taste of the tea due to too long or too short heating time.

[0010] Furthermore, according to the real-time remaining water level and the pre-acquired number of tea steaming times corresponding to the first boiling and steaming operation, the first tea steaming parameter is adjusted, specifically including: according to the number of tea steaming times corresponding to the first boiling and steaming operation, the first set water intake in the first tea steaming parameter is adjusted, and a second set water intake for a second boiling and steaming operation after the first boiling and steaming operation is determined, wherein the second set water intake is lower than the first set water intake; a current water replenishment amount is determined by the real-time remaining water level and the second set water intake; and the adjusted second tea steaming parameter is determined by a second heating time that is higher than the first heating time in the first tea steaming parameter and the current water replenishment amount.

[0011] Through the above technical solution, the steaming parameters are dynamically adjusted according to the real-time remaining water level and the number of times the tea is steamed, ensuring that each time the tea is steamed, the appropriate tea concentration and taste are maintained. As the number of times the tea is steamed increases, the flavor substances released by the tea leaves decrease. By reducing the amount of water intake and extending the heating time, this change can be compensated, so that users can enjoy stable tea quality at different stages of tea steaming. By precisely controlling the amount of water intake and the heating time, the situation of the tea being too strong or too weak is avoided, which improves the user's tea drinking experience and reduces the waste of tea leaves. As the number of times the tea is steamed increases, the amount of water intake is gradually reduced, which not only ensures the concentration of the tea, but also reduces unnecessary waste of water resources. By adjusting the heating time, the tea steaming process is made more efficient and energy consumption is reduced.

[0012] Furthermore, according to the number of tea steaming times corresponding to the first boiling and steaming tea operation, the first set water inlet amount in the first tea steaming parameter is adjusted to determine the second set water inlet amount for the second boiling and steaming tea operation that is located after the first boiling and steaming tea operation, which specifically includes: obtaining the preset initial set water amount corresponding to the first boiling and steaming tea operation; determining the water amount adjustment ratio according to the number of tea steaming times corresponding to the first boiling and steaming tea operation, and determining the second set water amount according to the water amount adjustment ratio and the initial set water amount.

[0013] Through the above technical scheme, the water intake is dynamically adjusted according to the number of times the tea is steamed, so that a more personalized tea brewing service can be provided to the user. Different numbers of tea steaming correspond to different water intakes, so that each time the tea is brewed, the appropriate concentration and taste can be maintained to meet the personalized needs of the user. The water intake required for each tea steaming can be accurately calculated, and precise control helps to avoid the situation where the tea is too strong or too weak, and improves the accuracy and stability of tea brewing; dynamic adjustment of the water intake can ensure the stable quality of each tea brewing, avoid changes in taste caused by too long or too short tea soaking time, and enhance the user's tea drinking experience; the user does not need to manually adjust the water intake, and the parameters can be automatically adjusted according to the number of tea steaming times, which reduces the user's operating difficulty and complexity and improves the user's satisfaction.

[0014] Furthermore, after performing the first boiling and steaming tea operation with the preset first tea steaming parameter, the method also includes: setting a tea steaming times counting task; under the triggering of the power-on signal, monitoring the boiling and steaming tea operation through the tea steaming times counting task, and when the boiling and steaming tea operation is monitored, performing a cumulative counting of the tea steaming times to determine the tea steaming times; under the triggering of the end of the insulation operation and / or the tea leaf replacement reminder, the counting result of the tea steaming times counting task is cleared.

[0015] Through the above technical scheme, by recording the number of times the tea is steamed, the use of the tea can be understood to avoid excessive use or waste of tea. At the same time, according to the remaining aroma and taste of the tea, the steaming parameters are adjusted to make full use of the tea and ensure that each cup of tea can release the best flavor.

[0016] Furthermore, tea steaming control is performed with the adjusted second tea steaming parameter, specifically including: determining a current water replenishment amount and a second heating duration in the second tea steaming parameter; determining a pumping control parameter of a water pump based on the current water replenishment amount, and controlling the water pump to perform a pumping operation with the pumping control parameter; detecting the real-time water level in the liquid container through the water level detection area to determine whether it satisfies a second set water level obtained in advance; when the real-time water level satisfies the second set water level, performing a boiling and steaming tea operation within the second heating duration.

[0017] Through the above technical scheme, the second tea steaming parameters, including the current water replenishment amount and the second heating time, are dynamically adjusted according to the number of tea steaming times and the real-time remaining water level, thereby realizing personalized tea steaming control and ensuring that each time the tea is steamed, the appropriate tea concentration and taste are maintained to meet the personalized needs of users; by accurately calculating the current water replenishment amount and determining the pumping control parameters (such as pumping rate, pumping time, etc.) accordingly, precise control of the pumping process is achieved, and the precise water replenishment method avoids the waste of water resources, while ensuring that the amount of water in the liquid container reaches the preset second set water inlet volume; during the pumping process, the water inlet level in the liquid container is monitored in real time through the water level detection area to ensure the accuracy and timeliness of the pumping operation, and when the real-time water inlet level reaches the second set water inlet volume, the water pump is automatically stopped to avoid excessive or insufficient pumping.

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

[0019] Through the above technical scheme, by combining the pumping time and the water pump flow reference data to calculate the reference pumping volume, and comparing it with the current water replenishment volume obtained by liquid level calculation, it is possible to timely discover possible errors in the water level detection process and make corresponding corrections, thereby improving the accuracy of water volume judgment; when it is found that 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 the preset error water volume threshold and correction conditions, it is possible to automatically determine whether the water level needs to be corrected, and determine the correction factor according to the size of the water volume deviation, thereby improving the accuracy and efficiency of the correction, and reducing the cost and difficulty of manual intervention.

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

[0021] Through the above technical scheme, by comparing the cumulative amount of soaking water with the threshold of the amount of water for steaming tea, it is possible to intelligently judge the number of times the tea leaves have been brewed and whether they need to be replaced, thereby avoiding the deterioration of the taste of the tea leaves due to excessive brewing, while also ensuring the full utilization of the tea leaves and improving the efficiency of tea use; when the cumulative amount of soaking water reaches the threshold of the amount of water for steaming tea that matches the current tea demand, a reminder to replace the tea leaves is automatically sent, so that the user does not need to frequently pay attention to the brewing status of the tea leaves, thereby improving the convenience and satisfaction of the user; the remaining water level in the liquid container is monitored in real time, and the insulation operation is terminated when the remaining water level is lower than the preset minimum water threshold, effectively avoiding overheating, damage or safety hazards caused by insufficient water; unnecessary energy consumption is avoided by precisely controlling the amount of water replenishment and the insulation operation. When the tea leaves have been used to the point where they need to be replaced, the water replenishment is stopped in time and the insulation is terminated when the water volume is low, which helps to reduce energy waste and achieve energy saving and consumption reduction.

[0022] Furthermore, the method also includes: obtaining the number of tea steaming times corresponding to the first boiling and steaming tea operation and the initial set water volume corresponding to the first boiling and steaming tea operation; determining the threshold adjustment ratio through the number of tea steaming times, and determining the tea brewing parameter adjustment threshold corresponding to the first boiling and steaming tea 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 water needs to be replenished and when the current water volume should be maintained for boiling and steaming tea according to the number of times the user takes water and the real-time remaining water volume, thereby ensuring that the concentration of each cup of tea remains within the user's expected range, avoiding the tea from being 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 water needs to be replenished, 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 taking behavior, thereby realizing intelligent control.

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

[0025] Through the above technical scheme, by executing the insulation process after the first boiling and steaming tea operation, insulation can ensure that the tea soup maintains a suitable temperature for a period of time, avoiding the tea soup from cooling down quickly and affecting the taste. In the insulation state, the aroma and taste of the tea soup can be better maintained, allowing users to taste high-quality tea soup for a long time; allowing users to drink tea soup at any time after the steaming of tea is completed, without worrying about the cooling of the tea soup, thereby improving the convenience of use. In addition, the appropriate insulation temperature can slow down the oxidation rate of substances in the tea soup, thereby extending the quality retention time of the tea soup.

[0026] At least one of the above technical solutions adopted in the embodiments of this specification can achieve the following beneficial effects:

[0027] 1. Traditional tea steaming equipment uses fixed tea brewing parameters in the cyclic tea brewing process, which causes the tea concentration to gradually decrease as the number of tea steaming increases, 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 tea steaming parameters according to the remaining water level and the number of tea steaming times, which can ensure that the appropriate tea concentration can be obtained each time the tea is steamed, thereby significantly improving the user's tea drinking experience;

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

[0029] 3. The traditional low water level and high water level metal electrode detection mechanism can only roughly judge the water level status in the container, and cannot realize real-time monitoring of any water level inside the container. The present technical solution adopts capacitive liquid level detection technology. Through capacitive liquid level detection technology, the remaining water level in the liquid container can be obtained in real time and accurately. When the user performs the tea water extraction operation, the real-time remaining water level will be compared with the preset tea brewing parameter adjustment threshold to decide whether the tea steaming parameters need to be adjusted, making the tea steaming process more flexible and accurate, and can be dynamically adjusted according to actual needs.

[0033] In order 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 in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0034] The embodiment of this specification provides a tea steaming control method based on capacitive liquid level detection. It should be noted that the execution subject in the embodiment of this specification can be a server or any device with data processing capabilities. Figure 1 A flow chart of a method for controlling steamed tea based on capacitive liquid level detection is provided in the embodiment of this specification, as shown in FIG. Figure 1 As shown, it mainly includes the following steps:

[0035] Step S101, after performing a first boiling and steaming tea operation with a preset first tea steaming parameter, a heat preservation process is performed.

[0036] In one embodiment of the present specification, the method in the embodiment of the present specification 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 arranged on the side wall of the liquid container, wherein a plurality of electrode sheets distributed longitudinally are arranged in the water level detection area. Figure 2 This is a schematic diagram of the distribution of electrodes in a water level detection area provided in an embodiment of this specification. The kettle of the tea bar machine is provided with the following Figure 2 The capacitance detection board shown includes a plurality of staggered electrode sheets, wherein a certain space is reserved between two adjacent electrode sheets, which is used as a water level judgment node to ensure that only one electrode sheet in a single row of electrode sheets can detect capacitance changes at the same time, thereby improving detection accuracy. The electrode sheets are arranged in a staggered manner, which can effectively avoid direct interference between adjacent electrode sheets, and a certain space is reserved between two adjacent electrode sheets, which is used as a water level judgment node. It is ensured that only one electrode sheet in a single row of electrode sheets can detect capacitance changes at the same time, avoiding misjudgment caused by multiple electrode sheets detecting capacitance changes at the same time, thereby improving detection accuracy.

[0037] like Figure 2 As shown, 11 self-capacitance electrode sheets are arranged in the water level detection area, and each self-capacitance electrode sheet corresponds to a different detection liquid level. For example, the liquid level range that can be detected by self-capacitor G18 is 400-500ml, the liquid level range corresponding to self-capacitor G29 is 400-600ml, self-capacitor G23 and G24 can detect 500-700ml, self-capacitor G25 can detect 600-800ml, self-capacitor G22 can detect 700-900ml, self-capacitor G26 can detect 800-1000ml, self-capacitor G21 can detect 900-1100ml, self-capacitor G27 can detect 1000-1200ml, self-capacitor G20 can detect 1100-1300ml, self-capacitor G28 can detect 1200-1400ml, and self-capacitor G19 can detect 1300-1500ml. Figure 2 In the staggered design shown, each 100ml liquid level has a corresponding detection electrode sheet, which can detect multiple liquid levels within 500-1400ml. For example, the 800ml liquid level can be judged by G25. When the water is submerged or nearly submerged by G25, the detection liquid level corresponding to G25 is triggered, and the purpose of detecting the 800ml liquid level can be achieved. In addition to G25, the purpose of detecting 800ml can also be achieved through the capacitance characteristics corresponding to G26 when water just touches.

[0038] Before performing the first boiling and steaming tea operation with the preset first tea steaming parameters, the method also includes: obtaining the user's first set water volume to determine the tea demand based on the first set water volume; determining the first heating time corresponding to the first boiling and steaming tea operation according to the tea demand; and boiling and steaming the tea leaves with the first set water volume for the first time with the first heating time.

[0039] In one embodiment of the present specification, the first boiling and steaming of tea is performed under the manual trigger of the user. The user sets the amount of water that the user needs to use for steaming tea according to his or her preferences and needs to obtain the user's first set water amount. It should be noted that the first set water amount here is the water requirement corresponding to the first tea steaming process, and the first set water amount should be within the operating capacity of the liquid container. Multiple set water amount trigger buttons within the operating capacity range can be set on the tea bar machine. When the user needs to boil and steam tea, the corresponding set water amount is selected by clicking the set water amount trigger button. Generally, the set water amount of the first brew of tea is set to the water amount within the capacity range, for example, the maximum set water amount allowed for a single pot. Since different water amounts correspond to different types of tea and tea weights, when the user sets the set water amount corresponding to the first boiling and steaming tea process, the user also selects the type of tea corresponding to the boiling and steaming tea.

[0040] After determining the first set water volume, the weight of tea leaves corresponding to the required type of tea leaves is determined according to the pre-set correspondence between the amount of tea leaves of the type of tea leaves and the amount of the first brewing. It should be noted that the correspondence between the amount of tea leaves and the amount of the first brewing here can be obtained through experimental data. For boiling and steaming tea tests of different types of tea leaves, the tea concentration corresponding to different brewing water amounts can be tested under a certain tea weight by controlling variables, and the test brewing water amount corresponding to the highest tea concentration in the tea concentration range acceptable to the public is used as the first brewing amount under this tea weight. In addition to the above method, the user can also choose the preferred tea concentration range by himself, and match the first brewing amount with the highest tea concentration in this tea concentration range. According to the above test method, the correspondence between the amount of tea leaves and the first brewing amount under different types of tea leaves is obtained.

[0041] According to the determined tea demand and the first set water volume, determine the first heating time corresponding to the first boiling and steaming tea operation. First, a data table containing tea types, tea weights, corresponding water volumes, and recommended heating times can be established. This data table can be established based on experimental data, user feedback, or the advice of professional tea artists. Look up the corresponding recommended basic heating time in the database. If the user selects a taste preference (such as strong, medium, or light), adjust the basic heating time according to this preference to obtain the first heating time. For example, strong tea may require a longer heating time, while light tea may require a shorter heating time. With the first heating time, boil and steam the tea leaves under the first set water volume for the first time.

[0042] Through the above technical scheme, by obtaining the user's first set water volume, the user's tea drinking needs can be accurately matched. No matter the user likes strong tea or light tea, the needs can be met by adjusting the water volume and the amount of tea leaves. The heating time is determined according to the water volume set by the user and the calculated tea demand, which can ensure that the taste of the steamed tea meets the user's expectations and improve the user's satisfaction. By determining the heating time based on the tea demand and the set water volume, the tea steaming process can be controlled more accurately to avoid poor taste of the tea due to too long or too short heating time.

[0043] In one embodiment of the present specification, after performing the first boiling and steaming tea operation with the preset first tea steaming parameter, the heat preservation process is performed. The first boiling and steaming tea operation here can be the first boiling and steaming tea, or it can be the subsequent boiling and steaming tea after the first boiling and steaming tea.

[0044] By executing the insulation process after the first boiling and steaming operation, insulation can ensure that the tea soup maintains a suitable temperature for a period of time, avoiding the tea soup from cooling down quickly and affecting the taste. In the insulation state, the aroma and flavor of the tea soup can be better maintained, allowing users to taste high-quality tea soup for a longer period of time; allowing users to drink tea soup at any time after the steaming is completed, without worrying about the tea soup cooling down, thereby improving the convenience of use. In addition, the appropriate insulation temperature can slow down the oxidation rate of substances in the tea soup, thereby extending the quality retention time of the tea soup.

[0045] After performing the first boiling and steaming tea operation with the preset first tea steaming parameter, the method also includes: setting a tea steaming times counting task; under the triggering of a power-on signal, monitoring the boiling and steaming tea operation through the tea steaming times counting task, and when the boiling and steaming tea operation is monitored, performing a cumulative counting of the tea steaming times to determine the tea steaming times; under the triggering of the end of the insulation operation and / or the tea leaf replacement reminder, the counting result of the tea steaming times counting task is cleared.

[0046] In one embodiment of the present specification, a tea steaming times counting task is set, which is started after power-on, monitors each boiling and steaming tea operation, and accumulates and counts the number of tea steaming times. When the steaming tea ends the insulation operation or triggers the tea replacement reminder, the counting result of the counting task will be cleared to allow the next round of counting. First, in the control system of the tea bar machine, a tea steaming times counting task is set to monitor the boiling and steaming tea operation. When the tea bar machine is powered on, the tea steaming times counting task is activated, that is, each time the power is turned on, the counting task starts to prepare to record the number of tea steaming times. The tea steaming times counting task can determine whether the boiling and steaming tea operation is in progress by monitoring the working status of key components such as the heating element and temperature sensor of the tea steamer and the user triggering the tea steaming function. After the user triggers the tea steaming function, once it is detected that the heating element starts to work and the temperature reaches the preset tea steaming temperature range, it is considered that a boiling and steaming tea operation has started. Each time the boiling and steaming tea operation is detected to start, the tea steaming times counting task will add one to the number of tea steaming times and record the number of tea steaming times that have been performed in real time. In two cases, the count result of the tea steaming times counting task will be cleared, one is the end of the keep warm operation, and the other is the tea change reminder. Generally, the keep warm operation will be performed after each tea brewing. The end of the keep warm operation indicates that the user's tea steaming process is over, and the count result will be cleared. In addition, when it is detected that the tea has been used a certain number of times or time and needs to be replaced, a tea change reminder will be triggered. At this time, the user can choose whether to change the tea immediately, and after confirming the replacement, the count result will also be cleared.

[0047] Through the above technical scheme, by recording the number of times the tea is steamed, the use of the tea can be understood to avoid excessive use or waste of tea. At the same time, according to the remaining aroma and taste of the tea, the steaming parameters are adjusted to make full use of the tea and ensure that each cup of tea can release the best flavor.

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

[0049] In one embodiment of the present specification, after the user performs at least one tea water extraction operation, the electrode sheet in the water level detection area is used to collect the real-time remaining water level in the liquid container. After the user extracts tea water, if there are operations of lifting a pot to extract water and placing the pot, liquid level fluctuations are generated during the process of placing the pot. The real-time remaining water level is detected by using the effect of the liquid level fluctuation on the capacitance of the electrode sheet. If the tea water extraction process is a direct water discharge, the remaining water level can be detected by using the effect of the drop in the water level during the water discharge process on the capacitance of the electrode sheet.

[0050] Through the above technical scheme, by real-time detection of the remaining water level, water can be replenished in time when the water level is too low, avoiding interruption of tea supply and improving the user's tea drinking experience; water extraction, heating and other parameters can be automatically adjusted according to the real-time water level to realize automated management and improve utilization efficiency; in addition, by detecting the real-time remaining water level after the user extracts tea, the user's drinking water volume can be reflected to a certain extent; through real-time water level detection, the heating and water extraction process can be controlled more accurately, 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 pre-acquired number of tea steaming times corresponding to the first boiling and steaming operation, and the tea steaming control is performed with the adjusted second tea steaming parameter.

[0052] In one embodiment of the present specification, after the user performs the tea water extraction operation, each time the tea water is extracted, a real-time remaining water level corresponds to the tea water extraction. As the number of times the water is extracted increases, the real-time remaining water level in the container gradually decreases, that is, the remaining water volume gradually decreases. When the remaining water volume meets the preset tea brewing parameter adjustment threshold, that is, it is less than the tea brewing parameter adjustment threshold, it means that the user has extracted a large amount of water at this time, and the remaining amount in the container is small, and water needs to be replenished, and then the tea is boiled and steamed again. When the remaining water volume does not meet the preset tea brewing parameter adjustment threshold, that is, it is greater than the tea brewing parameter adjustment threshold, it is considered that the user drinks a small amount of tea and does not need to be replenished and boiled. Therefore, when the real-time remaining water level does not meet the preset tea brewing parameter adjustment threshold, the insulation process is executed.

[0053] In one embodiment of the present specification, different tea leaves have different requirements for water volume and tea steaming parameters. As the number of tea steaming times increases and the amount of 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 tea steaming parameter is adjusted according to the real-time remaining water level and the number of tea steaming times corresponding to the first boiling and steaming operation, and the tea steaming control is performed with the adjusted second tea steaming parameter. By adjusting the tea steaming parameters, it is possible to better adapt to the current state of the tea leaves and ensure that each brew of tea can achieve the best taste. When the amount of remaining water is small, if the same tea steaming parameters continue to be used, the tea soup concentration may be too high, affecting the taste. By adjusting the tea steaming parameters, such as lowering the temperature or shortening the tea steaming time, the tea soup concentration can be reduced to make it more moderate.

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

[0055] In one embodiment of the present specification, when determining the threshold value for adjusting the tea brewing parameters, it is related to the initial set water volume corresponding to the first boiling and steaming tea operation, that is, the first brew. The initial set water volume corresponding to the first boiling and steaming tea operation here can be defaulted to the rated water volume of the liquid container. In addition, since the number of tea steaming times will affect the subsequent setting of the tea brewing parameters, with the increase in the number of tea steaming times, the tea concentration gradually decreases under the same water volume, that is, the more tea steaming times, the less water is used for the subsequent boiling and steaming tea operations. Therefore, the number of tea steaming times corresponding to the first boiling and steaming tea operation and the initial set water volume corresponding to the first boiling and steaming tea operation are obtained to determine the threshold value for adjusting the tea brewing parameters corresponding to the first boiling and steaming tea operation.

[0056] First, the threshold adjustment ratio is determined by the number of times of steaming tea, according to the formula [1-(x-1) / n]*(1 / 2), where x is the number of times of steaming tea corresponding to the first boiling and steaming tea operation, and n is the preset adjustment step. The adjustment step here is related to the number of brewing times corresponding to the demand for tea leaves, that is, the more times of brewing, the larger the corresponding adjustment step, and the number of brewing times can be directly set as the adjustment step. For example, under the initial set water volume, after brewing 4 pots, the concentration of tea has been reduced to the drinking concentration threshold, and the adjustment step can be set to 4. After determining the threshold adjustment ratio in the above manner, the tea brewing parameter adjustment threshold corresponding to the first boiling and steaming tea operation is determined by multiplying the threshold adjustment ratio and the initial set water volume. For example, when the number of steaming tea corresponding to the steaming operation is 1, that is, the first time of brewing tea, the corresponding tea brewing parameter adjustment threshold is 1 / 2 of the initial set water volume; when the number of steaming tea corresponding to the steaming operation is 2, the corresponding tea brewing parameter adjustment threshold is 3 / 8 of the initial set water volume.

[0057] Through the above technical solution, the tea brewing parameter adjustment threshold can accurately determine when water needs to be replenished and when the current water volume should be maintained for boiling and steaming tea according to the number of times the user takes water and the real-time remaining water volume, thereby ensuring that the concentration of each cup of tea remains within the user's expected range, avoiding the tea from being 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 water needs to be replenished, 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 taking behavior, thereby realizing intelligent control.

[0058] The first tea-steaming parameter is adjusted according to the real-time remaining water level and the number of tea-steaming times corresponding to the first boiling and tea-steaming operation acquired in advance, specifically including: adjusting the first set water inlet in the first tea-steaming parameter according to the number of tea-steaming times corresponding to the first boiling and tea-steaming operation, and determining a second set water inlet in a second boiling and tea-steaming operation that is located after the first boiling and tea-steaming operation, wherein the second set water inlet is lower than the first set water inlet; determining a current water replenishment amount according to the real-time remaining water level and the second set water inlet; and determining the adjusted second tea-steaming parameter according to a second heating time that is higher than the first heating time in the first tea-steaming parameter and the current water replenishment amount.

[0059] In one embodiment of the present specification, if the real-time remaining water level is less than the 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 times corresponding to the first boiling and steaming operation. The number of tea steaming times corresponding to the first boiling and steaming operation reflects the number of times the current tea is boiled. The higher the number of boiling times, the lower the tea concentration is under the same water volume. In order to ensure the tea concentration when the user drinks tea, according to the number of tea steaming times corresponding to the first boiling and steaming operation, the water inlet of the second boiling and steaming operation located after the first boiling and steaming operation is set with a second set water inlet lower than the first set water inlet in the first tea steaming parameter. After determining the second set water inlet corresponding to the second boiling and steaming operation, the current water replenishment amount is determined by the difference between the second set water inlet 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 boiling and steaming operation. As the number of tea steaming times increases, the set water volume gradually decreases, and the tea steaming time is extended at the same time. The adjusted second tea steaming parameter is determined with a second heating time higher than the first heating time in the first tea steaming parameter and the current water replenishment amount.

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

[0061] Through the above technical solution, the steaming parameters are dynamically adjusted according to the real-time remaining water level and the number of times the tea is steamed, ensuring that each time the tea is steamed, the appropriate tea concentration and taste are maintained. As the number of times the tea is steamed increases, the flavor substances released by the tea leaves decrease. By reducing the amount of water intake and extending the heating time, this change can be compensated, so that users can enjoy stable tea quality at different stages of tea steaming. By precisely controlling the amount of water intake and the heating time, the situation of the tea being too strong or too weak is avoided, which improves the user's tea drinking experience and reduces the waste of tea leaves. As the number of times the tea is steamed increases, the amount of water intake is gradually reduced, which not only ensures the concentration of the tea, but also reduces unnecessary waste of water resources. By adjusting the heating time, the tea steaming process is made more efficient and energy consumption is reduced.

[0062] According to the number of tea steaming times corresponding to the first boiling and steaming operation, the first set water inlet amount in the first tea steaming parameter is adjusted to determine the second set water inlet amount for the second boiling and steaming operation that is located after the first boiling and steaming operation, specifically including: obtaining an initial set water amount corresponding to a pre-set first boiling and steaming operation; determining a water amount adjustment ratio according to the number of tea steaming times corresponding to the first boiling and steaming operation, and determining the second set water amount according to the water amount adjustment ratio and the initial set water amount.

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

[0064] Through the above technical scheme, the water intake is dynamically adjusted according to the number of times the tea is steamed, so that a more personalized tea brewing service can be provided to the user. Different numbers of tea steaming correspond to different water intakes, so that each time the tea is brewed, the appropriate concentration and taste can be maintained to meet the personalized needs of the user; using the pre-set formulas and parameters (such as the adjustment step n and the initial set water volume V1), the water intake required for each tea steaming can be accurately calculated, and precise control helps to avoid the situation where the tea is too strong or too weak, and improves the accuracy and stability of tea brewing; dynamic adjustment of the water intake can ensure the stable quality of each tea brewing, avoid changes in taste caused by too long or too short tea soaking time, and enhance the user's tea drinking experience; the user does not need to manually adjust the water intake, and the parameters can be automatically adjusted according to the number of tea steaming times, which reduces the user's operating difficulty and complexity and improves the user's satisfaction.

[0065] The tea steaming control is performed with the adjusted second tea steaming parameter, specifically including: determining a current water replenishment amount and a second heating duration in the second tea steaming parameter; determining a pumping control parameter of a water pump based on the current water replenishment amount, and controlling the water pump to perform a pumping operation with the pumping control parameter; detecting the real-time water level in the liquid container through the water level detection area to determine whether it satisfies a second set water level obtained in advance; when the real-time water level satisfies the second set water level, performing a boiling and steaming tea operation within the second heating duration.

[0066] In one embodiment of the present specification, the current water replenishment amount and the second heating time in the second tea steaming parameter are determined. The current water replenishment amount is the amount of water that the water pump needs to pump, and the pumping control parameters such as the pumping rate and the pumping time are determined accordingly. The pumping control parameters are sent to the water pump to control it to perform the pumping operation and pump 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 the water level detection area. When the real-time water level reaches the second set water inlet, it is considered that the pumping operation is completed and the water pump is stopped. After confirming that the water volume in the liquid container has reached the second set water inlet, the heating device is started to start the heating process. The water in the liquid container is continuously heated during the second heating time so that the tea leaves can fully release the flavor substances and complete the boiling and steaming tea operation.

[0067] Through the above technical scheme, the second tea steaming parameters, including the current water replenishment amount and the second heating time, are dynamically adjusted according to the number of tea steaming times and the real-time remaining water level, thereby realizing personalized tea steaming control and ensuring that each time the tea is steamed, the appropriate tea concentration and taste are maintained to meet the personalized needs of users; by accurately calculating the current water replenishment amount and determining the pumping control parameters (such as pumping rate, pumping time, etc.) accordingly, precise control of the pumping process is achieved, and the precise water replenishment method avoids the waste of water resources, while ensuring that the amount of water in the liquid container reaches the preset second set water inlet volume; during the pumping process, the water inlet level in the liquid container is monitored in real time through the water level detection area to ensure the accuracy and timeliness of the pumping operation, and when the real-time water inlet level reaches the second set water inlet volume, the water pump is automatically stopped to avoid excessive or insufficient pumping.

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

[0069] In one embodiment of the present specification, there will be errors in the detection process of the real-time water level during the pumping process and the real-time remaining water level after the kettle is put back. In order to ensure the judgment accuracy of the water volume, correction can be made in combination with the actual water addition time during the pumping process. The pumping time from the start of the pumping to the current moment is recorded. This pumping time is dynamically changing and increases continuously as the pumping process proceeds. The pump flow reference data of the pumping pump is obtained or stored in advance, indicating the amount of water that the pumping pump can extract per unit time. Here, the pump flow reference data can be the average of the normal pump flow. Based on the product of the current pumping time and the pump flow reference data, the actual amount of water extracted by the pumping pump during the current pumping time is calculated, that is, the reference pumping volume. The current water replenishment volume is calculated by comparing the reference pumping volume corresponding to the actual pumping of the pump and the liquid level. If the water volume deviation between the two meets the preset correction condition, it indicates that there may be a problem in the water level detection process and the real-time water level needs to be corrected.

[0070] In one embodiment of the present specification, an allowable error water volume threshold is preset. When the water volume deviation between the reference pumping volume and the current water replenishment volume is within 10% of the error water volume threshold, it is considered that the water level detection is accurate and no correction is required; when the water volume deviation between the reference pumping volume and the current water replenishment volume is within 10% to 30% of the error water volume threshold, it means that the correction condition is met. When the correction condition is met, the correction factor is determined by the ratio of the water volume deviation and the error water volume threshold. The detected real-time water level is corrected by the correction factor. The real-time water level here can be the real-time pumping water level during the pumping process, or it can be the real-time remaining water level after the kettle is put back. In correcting the detected real-time water level, the correction value is determined by the product of the correction factor and the real-time water level. If the water volume deviation is a positive number, that is, the reference pumping volume corresponding to the actual pumping of the water pump is greater than the current water replenishment volume calculated by the liquid level, it means that the real-time water level detection value is low, and the corrected water level value is determined by the sum of the real-time water level detection value and the correction value. On the contrary, if the water volume deviation is negative, that is, the reference water volume corresponding to the actual water pumping of the water pump is less than the current water replenishment volume calculated by the liquid level, it means that the real-time water level detection value is too high, and the corrected water level value is determined by the difference between the real-time water level detection value and the correction value. When the water volume deviation between the reference water pumping volume and the current water replenishment volume exceeds 30% of the error water volume threshold for multiple consecutive times, the number of deviation abnormalities is counted, and when the number of deviation abnormalities exceeds the preset warning number threshold, an abnormal reminder is sent.

[0071] Through the above technical scheme, by combining the pumping time and the reference data of the pump flow to calculate the reference pumping volume, and comparing it with the current water replenishment volume obtained by the liquid level calculation, it is possible to timely discover the errors that may exist in the water level detection process and make corresponding corrections, thereby improving the accuracy of water volume judgment; when it is found that the water volume deviation meets the preset correction conditions, the real-time water level is automatically corrected to avoid operational errors or system instability caused by water level detection errors; through the preset error water volume threshold and correction conditions, it is possible to automatically determine whether the water level needs to be corrected, and determine the correction factor according to the size of the water volume deviation, thereby improving the accuracy and efficiency of the 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 for multiple consecutive times, the system will count the number of deviation abnormalities and send an abnormal reminder when the number exceeds the warning number threshold, which is helpful to timely discover and deal with potential problems and avoid the expansion of faults or more serious consequences.

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

[0073] In one embodiment of the present specification, in each boiling and steaming tea operation, the water replenishment amount is recorded and accumulated, that is, the amount of water that needs to be added additionally for each boiling and steaming tea operation. This accumulated water replenishment amount changes dynamically and increases continuously with each operation. Based on the accumulated water replenishment amount in multiple boiling and steaming tea operations, and the initial set water amount corresponding to the first boiling and steaming tea operation (that is, the amount of water at the first operation), the accumulated water amount is calculated, which represents the total amount of water in the liquid container from the first operation to the current moment. The threshold value of the amount of water for steaming tea corresponding to different tea demand is pre-stored. The threshold value of the amount of water for steaming tea is determined based on factors such as the type, quality, and number of brewing of tea leaves, indicating the maximum amount of tea water that can be steamed during the steaming tea process under a certain tea demand. When the accumulated amount of water reaches the threshold value of the amount of water for steaming tea that matches the current tea demand, a tea replacement reminder is sent to prompt the user to replace new tea leaves. When the cumulative amount of water reaches the steaming water threshold that matches the current tea demand, the tea is considered to have been used for a long time, so the user is reminded to change the tea. In addition, since the set steaming water threshold has been exceeded at this time, no water will be added each time the user puts the pot back. In addition, the remaining water level in the liquid container, that is, the amount of water currently remaining in the container, is monitored in real time. When the remaining water level is lower than the preset minimum water threshold, the insulation operation will end to prevent equipment damage or safety hazards caused by insufficient water.

[0074] Through the above technical scheme, by comparing the cumulative amount of soaking water with the threshold of the amount of water for steaming tea, it is possible to intelligently judge the number of times the tea leaves have been brewed and whether they need to be replaced, thereby avoiding the deterioration of the taste of the tea leaves due to excessive brewing, while also ensuring the full utilization of the tea leaves and improving the efficiency of tea use; when the cumulative amount of soaking water reaches the threshold of the amount of water for steaming tea that matches the current tea demand, a reminder to replace the tea leaves is automatically sent, so that the user does not need to frequently pay attention to the brewing status of the tea leaves, thereby improving the convenience and satisfaction of the user; the remaining water level in the liquid container is monitored in real time, and the insulation operation is terminated when the remaining water level is lower than the preset minimum water threshold, effectively avoiding overheating, damage or safety hazards caused by insufficient water; unnecessary energy consumption is avoided by precisely controlling the amount of water replenishment and the insulation operation. When the tea leaves have been used to the point where they need to be replaced, the water replenishment is stopped in time and the insulation is terminated when the water volume is low, which helps to reduce energy waste and achieve energy saving and consumption reduction.

[0075] Through the technical solution of the embodiments of this specification, traditional tea steaming equipment adopts fixed tea brewing parameters in the cyclic tea brewing process, which causes the tea concentration to gradually decrease with the increase of the number of tea steaming times, affecting the user's tea drinking experience. The present technical solution ensures that the appropriate tea concentration can be obtained each time the tea is steamed, thereby significantly improving the user's tea drinking experience. In the prior art, users often choose to discard the tea and re-steam the tea because of insufficient tea concentration, which not only causes a waste of water resources, but also requires the user to interrupt the tea drinking process and wait for the tea to be steamed again. The present technical solution accurately controls the tea steaming parameters and the remaining water level to adjust the tea steaming parameters according to the residual water level and the number of tea steaming times. The capacitive liquid level detection technology can be used to detect the remaining water level in the liquid container in real time and accurately. When the user performs the tea-taking operation, the real-time remaining water level will be compared 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 accurate, and can be dynamically adjusted according to actual needs.
