Description

Technical Field

[0001] The invention belongs to the technical field of intelligent selenium-hydrogen kettles, and in particular relates to a control method for an intelligent selenium-hydrogen kettle. Background Art

[0002] The selenium-hydrogen pot is a health-preserving selenium-hydrogen pot that combines the functions of selenium-rich and hydrogen-rich. It aims to provide users with healthy drinking water rich in hydrogen and selenium through technical means such as electrolysis.

[0003] As a new healthy home appliance product, the selenium hydrogen kettle combines the two health-preserving functions of hydrogen and selenium, providing a new choice for people who pursue a healthy life. The patent with publication number CN117602725A also discloses a selenium hydrogen water cup, including: a cup cover, a cup body and a base, the cup cover is connected to the cup body by a first thread, the cup body is connected to the base by a second thread, a power supply is arranged in the base, a selenium hydrogen module is arranged above the power supply, a control button and a charging port are arranged on the side wall of the base, and the power supply is electrically connected to the selenium hydrogen module, the control button and the charging port. A selenium hydrogen water cup is provided, which can prepare selenium hydrogen water containing hydrogen and selenium elements, and can also directly absorb hydrogen through a selenium hydrogen tube, has a variety of different modes, and is easy to use.

[0004] However, with regard to the selenium hydrogen kettle, there are many related products on the market. By building natural selenium stone and related hydrogen production equipment into the selenium hydrogen kettle, it can have good hydrogen production function. However, there is a lack of a good control method for the timing of hydrogen production and the related hydrogen production time, which makes it more convenient to use. It is especially inconvenient for office workers or some people who basically need to replenish water at fixed time intervals. Especially when it comes to the preparation of hydrogen, due to the solubility relationship between hydrogen and water, it is easy to diffuse out, and it is easier to diffuse as the temperature rises. It is a difficult problem to provide a reasonable hydrogen production time to ensure that the hydrogen content is high when the user drinks. Based on this, a solution is provided. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes a control method for an intelligent selenium hydrogen kettle, which specifically comprises the following steps: In view of the time taken by the selenium hydrogen kettle to produce hydrogen, starting from the base temperature, observe the time required for hydrogen to decrease from the set concentration to the lower limit concentration at this temperature, so as to obtain the escape velocity of hydrogen at this base temperature. This is carried out several times in succession, and then according to the data distribution of several escape velocities, the unreasonable data is eliminated, and the mean of the remaining data is marked as the nuclear escape velocity. Then, the same treatment is carried out at different temperatures to obtain a comparison table of temperature and nuclear escape velocity. The peak values ​​of hydrogen concentration in the selenium hydrogen pot at different temperatures are obtained, the peak data are eliminated, and the mean of the remaining data is marked as the hydrogen peak value; the time required for the hydrogen concentration in the selenium hydrogen pot to reach the peak value is obtained, the time data is eliminated, and the mean of the remaining data is marked as the hydrogen production time consumption, and finally a mapping table of temperature, nuclear escape velocity, hydrogen peak value, and hydrogen production time consumption is obtained; Then, data on the user's drinking habits is collected, and the intervals between the user's drinking water are collected. Similarly, unreasonable data is eliminated based on the numerical distribution of the intervals, and the interval is determined based on the remaining intervals after elimination; When the user selects mode 2, each time the user is detected to be drinking water, the countdown will automatically start according to the corresponding time of the judgment interval, and hydrogen production will start after the countdown ends; When hydrogen production starts, the water temperature at that time will be automatically obtained, and the hydrogen production time at the corresponding temperature will be automatically obtained. Hydrogen will be prepared according to the hydrogen production time, and then the corresponding nuclear escape velocity will be obtained. The time required for the hydrogen content peak corresponding to the current temperature to drop to 70% is calculated, and the time is marked as the reminder time; After hydrogen production is completed, the countdown will automatically start according to the reminder time.

[0006] Furthermore, the specific method of obtaining the nuclear escape velocity is: Set the hydrogen production concentration and adjust the hydrogen content in the water to the set concentration. The set concentration here is pre-set by the administrator; Set a base temperature, use the sample to heat water to the base temperature from the base temperature, and then prepare hydrogen. After the hydrogen concentration is adjusted to the set concentration, the hydrogen concentration in the water is monitored in real time. When it drops to the lower limit concentration, the lower limit concentration and the time to reach the lower limit concentration are obtained, thereby obtaining the escape velocity of hydrogen at the base temperature; Repeat several times to obtain several escape velocities at the base temperature, and eliminate unreasonable data; Add the new temperature to the basic temperature in sequence until the temperature data is less than or equal to 100 degrees; The continuity increases the temperature each time according to the newly added temperature value, and processes it in the same way as the basic temperature. The accumulated temperature is relabeled as the existence target each time, and the mapping relationship between the existence target and the nuclear escape velocity is obtained.

[0007] Furthermore, the lower limit concentration is preset by the administrator, and the additional temperature is set by the administrator. Furthermore, the specific method of eliminating unreasonable data is as follows: Mark several escape velocities as Ti, i=,...,n, indicating that there are n escape velocities, obtain the mean value P of Ti, and then use the formula to calculate the discrete evaluation value L of Ti. The specific calculation formula is: ; When L exceeds L1, L1 is the value preset by the administrator. At this time, Ti is automatically selected in order of |Ti-P| from small to large. Each time a value is selected, it is eliminated. After elimination, the discrete evaluation value of the remaining Ti is recalculated. If it still exceeds L1, the next Ti is automatically selected, deleted, and the discrete evaluation value is recalculated until the discrete evaluation value does not exceed L1. The remaining Ti is obtained, and the mean value of Ti is marked as the nuclear escape velocity at the corresponding base temperature.

[0008] Furthermore, the specific method for collecting data on the user's drinking habits to obtain the determination interval is: The interval time of each time the user drinks water is collected. Here, the collection starts from the user's most recent drinking time, and is pushed forward for several times to obtain several interval times Gj, j=1, ..., m, where m is set by the administrator; Then recalculate the discrete evaluation value of Gj. When the discrete evaluation value exceeds the preset value L2, delete it in the same way as Ti until the discrete evaluation value does not exceed L2, and get the remaining Gj value. Sort Gj from small to large, and mark its middle value as the judgment interval. Of course, if the number of deleted items exceeds 50% of the m value, an invalid signal is generated, and the judgment interval will be automatically invalidated.

[0009] Furthermore, the drinking action is determined in the following manner: when the selenium hydrogen kettle is powered off and then powered on again at Ty time, it indicates that the user has taken the drinking action, where Ty is a preset time.

[0010] Furthermore, if there are two intermediate values, the average of the two intermediate values ​​is taken and marked as the decision interval.

[0011] Furthermore, hydrogen production also includes mode 1, in which the hydrogen production process will not proceed until the user presses a button; when an invalid signal is generated, hydrogen production can only be performed through mode 1.

[0012] Furthermore, the method further includes a step of adjusting the time consumption of hydrogen production, and the specific method of adjusting the time consumption of hydrogen production is as follows: By obtaining the volume of the upper water level of the selenium hydrogen kettle, and then obtaining the time it takes to heat to 100 degrees, the value obtained by dividing the volume by the time and then by 100 is marked as the standard number; Before each subsequent hydrogen production, the most recent heating data will be obtained to obtain the time required to increase the water temperature by one degree, which will be marked as the actual number. After the actual number is divided by the standard number, the resulting value will be marked as the real-time ratio; Multiply the hydrogen production time by the real-time ratio, and the resulting value is marked as the real-time hydrogen production time; Hydrogen production is performed based on the time taken to produce hydrogen in real time Compared with the prior art, the present invention has the following beneficial effects: The present invention analyzes the nuclear escape velocity, hydrogen content peak and hydrogen production time of hydrogen at different temperatures, and combines the analysis of the user's drinking habits. Thus, hydrogen can be produced in advance according to the user's drinking habits, ensuring that the user can drink water with the highest hydrogen concentration and guaranteeing hydrogen intake. At the same time, the remaining water in the selenium hydrogen kettle can be analyzed according to the heating time, and the hydrogen production time can be adjusted in time. The present invention is simple, effective and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-2 The present application provides a control method for an intelligent selenium hydrogen kettle, which specifically comprises the following steps: Step 1: Observe hydrogen escape. The specific observation method is as follows: Step 1: First, obtain a selenium hydrogen kettle as a sample, and the escape velocity when heating hot water to different temperatures; first set the hydrogen production concentration, and adjust the hydrogen content in the water to the set concentration. The set concentration here is pre-set by the administrator; here, nanobubble technology can be used to evenly disperse hydrogen in the water in the form of tiny bubbles to form a stable nanobubble structure. This technology can significantly slow down the rise and release speed of hydrogen, allowing hydrogen to remain in the water for a longer time. This is an existing technology and will not be explained in detail; Similarly, the hydrogen involved in this application is prepared by the following method, specifically: The principle of producing hydrogen through electrolysis of water by proton exchange membrane mainly involves the decomposition process of water molecules under the action of electric field, and the key role of proton exchange membrane in it; the following is a detailed explanation: Water molecules decompose; at the anode, which is the positive electrode, water molecules undergo an oxidation reaction under the action of a catalyst such as a precious metal iridium catalyst, lose electrons, and generate oxygen and hydrogen ions (H+); this process can be expressed as: 2H2O = 4H+ +4e- + O2.

[0016] The role of the proton exchange membrane; the generated hydrogen ions are conducted to the cathode (negative electrode) through the proton exchange membrane (PEM) under the action of the electric field; the proton exchange membrane is a solid electrolyte that allows protons (positively charged hydrogen ions) to pass through while preventing electrons from passing through, thereby achieving the effective separation of hydrogen and oxygen during water electrolysis; Hydrogen generation: At the cathode, hydrogen ions gain electrons, undergo a reduction reaction, and generate hydrogen. This process can be expressed as: 4H+ + 4e- = 2H2. Due to the effect of the proton exchange membrane, the generated hydrogen and oxygen are effectively separated at both ends of the electrolyzer, thus achieving high-purity hydrogen generation. Step 2: Set a base temperature, and use the sample to heat water to the base temperature from the base temperature, and then prepare hydrogen. After adjusting the hydrogen concentration to the set concentration, monitor the hydrogen concentration in the water in real time. When it drops to the lower limit concentration, the lower limit concentration is preset by the administrator. The lower limit concentration and the time to reach the lower limit concentration are obtained, so as to obtain the escape velocity of hydrogen at the corresponding temperature during this experiment. The specific calculation can be obtained by subtracting the lower limit concentration from the set concentration and then dividing it by the time to get the velocity; Step 3: Repeat several times to obtain several escape velocities at the base temperature, and remove unreasonable data. The specific removal method is: Mark several escape velocities as Ti, i=,...,n, indicating that there are n escape velocities, obtain the mean value P of Ti, and then use the formula to calculate the discrete evaluation value L of Ti. The specific calculation formula is: ; When L exceeds L1, L1 is the value preset by the administrator. At this time, Ti is automatically selected in the order of |Ti-P| from small to large. Each time a value is selected, it is eliminated. After elimination, the discrete evaluation value of the remaining Ti is recalculated. If it still exceeds L1, the next Ti is automatically selected, deleted, and the discrete evaluation value is recalculated until the discrete evaluation value does not exceed L1. The remaining Ti is obtained, and its mean is marked as the nuclear escape velocity at the corresponding base temperature; Step 4: Then add the new temperature to the base temperature. The new temperature is generally set by the administrator. In this embodiment, it can be two degrees. Of course, five degrees can also be selected. In this way, the overall amount of data to be monitored will be reduced, but the accuracy of escape analysis will be reduced. The base temperature is added to the new temperature in sequence until the temperature data is less than or equal to 100 degrees; here, degrees refer to Celsius; Step 6: Continuously increase the temperature each time according to the newly added temperature value, and process it according to the processing method of Step 2-Step 3, re-mark all temperatures as existing targets, and obtain the mapping relationship between existing targets and nuclear escape speed; Step 6: Synchronously, the peak values ​​of hydrogen concentration of water in the selenium hydrogen kettle at different temperatures are obtained in the same way, and are marked as hydrogen-containing peak values. The time required to prepare water with hydrogen-containing peak values ​​is also obtained synchronously, and is marked as hydrogen production time consumption. Thus, a mapping relationship between the existence target and the nuclear escape velocity, hydrogen-containing peak value, and hydrogen production time consumption is obtained. Here, hydrogen-containing peak value refers to the highest concentration of hydrogen in water per unit volume. Step 2: Get the user's drinking habits. The specific method is: The interval time of each time the user drinks water is collected. Here, the collection starts from the last time the user drinks water, and the collection is pushed forward for several times to obtain several interval times Gj, j=1,...,m, which means that m data are collected. m is set by the administrator and is generally 50; The drinking action is determined as follows: when the selenium hydrogen kettle is powered off and then powered on again at Ty time, it indicates that the user has taken the drinking action. Ty is the preset time, which is generally 30 seconds. Then recalculate the discrete evaluation value of Gj. When the discrete evaluation value exceeds the preset value L2, delete it in the same way as Ti until the discrete evaluation value does not exceed L2, and get the remaining Gj value. Sort Gj from small to large, and mark its middle value as the judgment interval. If there are two middle values, take the average of the two middle values ​​as the judgment interval. Of course, if the number of deleted values ​​exceeds 50% of the m value, an invalid signal is generated, and the judgment interval will be automatically invalidated. At this time, hydrogen can only be produced through mode 1. Step 3: Produce hydrogen according to user needs. The specific method is as follows: This application sets two hydrogen production modes, which can be selected by the user through buttons; Mode 1: Hydrogen production will start only after the user presses the button; Mode 2: Every time the user is detected drinking water, a countdown will be automatically performed. After the countdown is over, hydrogen production will be performed. The countdown duration is based on the judgment interval. When hydrogen production starts, the water temperature at that time will be automatically obtained. The reason for obtaining the water temperature here is that the water temperature is not necessarily at 100 degrees. It may be set to keep warm at other temperatures. At this time, the hydrogen production time at the corresponding temperature will be automatically obtained, and hydrogen will be prepared according to the hydrogen production time. Then the corresponding nuclear escape velocity will be obtained, and the time required for the hydrogen content peak corresponding to the current temperature to drop to 70% will be calculated, and this time will be marked as the reminder time; After hydrogen production is completed, it will automatically count down according to the reminder time to remind the user to pour water and drink water as soon as possible; As the second embodiment of the present invention, this embodiment is carried out on the basis of the first embodiment. The difference from the first embodiment is that the second embodiment adjusts the hydrogen production time according to the remaining water in the selenium hydrogen kettle, while the first embodiment does not have this function. The specific method of adjusting the hydrogen production time in the present embodiment is as follows: SS1: First, determine the amount of water remaining in the selenium hydrogen kettle. The specific determination method is: When the upper limit water level is reached in the selenium hydrogen kettle, the time required for each degree of temperature rise is obtained. This method can be achieved by obtaining the volume of the upper limit water level of the selenium hydrogen kettle, and then obtaining the time to heat to 100 degrees. The value obtained by dividing the volume by the time and then by 100 is marked as the standard number; Before each subsequent hydrogen production, the most recent heating data will be obtained to obtain the time required to increase the water temperature by one degree, which will be marked as the actual number. After the actual number is divided by the standard number, the resulting value will be marked as the real-time ratio; Multiply the hydrogen production time by the real-time ratio, and the resulting value is marked as the real-time hydrogen production time; Hydrogen is prepared according to the time taken for real-time hydrogen production.

[0017] Some of the data in the above formula are calculated by removing the dimensions and taking their numerical values. The formula is a formula that is closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.

[0018] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
