BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of a microphone detection method described in the present invention. DETAILED DESCRIPTION

[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. The embodiments described are only a 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.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0017] One embodiment of the present invention provides a microphone detection method, the method comprising: Obtain multimodal data during the atomization process of electronic cigarettes; Based on the multimodal data of the electronic cigarette atomization process, the comprehensive influencing factors of temperature and humidity, the compensation factors of inhalation intensity and the correction factors of inhalation duration are calculated respectively, and the optimal atomizer power is calculated according to the comprehensive influencing factors of temperature and humidity, the compensation factors of inhalation intensity and the correction factors of inhalation duration; Adjusting the airflow channel of the electronic cigarette according to multimodal data during the atomization process of the electronic cigarette; Adjust the working mode of the atomizer according to the calculated optimal atomizer power.

[0018] The working principle and effect of the above technical solution are as follows: the multimodal data in the atomization process of electronic cigarettes covers multiple aspects of information, mainly including: temperature and humidity data: the temperature and humidity of the surrounding environment of the electronic cigarette are collected in real time through the temperature and humidity sensor. The ambient temperature and humidity will affect the physical properties of the smoke oil (such as viscosity, evaporation rate) and the working efficiency of the atomizer, and then affect the atomization effect; inhalation action data: the microphone is used to detect the user's inhalation action, and the inhalation start time and end time are recorded to calculate the inhalation time. At the same time, the maximum air pressure change value during the inhalation process is detected to characterize the inhalation intensity. Different inhalation times and intensities will cause users to have different requirements for the amount of smoke and taste. Temperature and humidity comprehensive influence factor: This factor comprehensively considers the nonlinear effects of temperature and humidity on the atomization effect. When the temperature deviates from the optimal working temperature and the humidity deviates from the optimal working humidity, it will have an adverse effect on the atomization process of the smoke oil. The temperature and humidity comprehensive influence factor is calculated by a specific formula to reflect the degree of influence of the combined effect of temperature and humidity on the atomization effect. It is calculated according to the maximum air pressure change value during the inhalation process. Different users have different inhalation intensities. In order to meet the diverse needs of users, this factor is used to compensate for the atomizer power. For example, when the inhalation intensity is strong, a higher power is required to produce enough smoke. The inhalation time correction factor takes into account the impact of the inhalation time on the atomization effect. Short-term inhalation and long-term inhalation have different requirements for the consumption of e-liquid and the atomization effect. The inhalation time correction factor is calculated based on the comparison results of the inhalation time with the preset minimum effective inhalation time and the maximum reasonable inhalation time.

[0019] The optimal atomizer power is calculated based on the above three factors. The airflow channel of the electronic cigarette is adjusted according to the multimodal data in the atomization process of the electronic cigarette, especially the temperature and humidity data. In a high humidity environment, reduce the degree of opening and closing of the airflow channel to reduce the amount of water vapor entering, prevent water vapor from affecting the atomization effect and producing condensed water; in a low temperature environment, appropriately reduce the airflow channel to make the air stay longer in the electronic cigarette and improve the atomization efficiency. According to the calculated optimal atomizer power, the working mode of the atomizer is divided into low-power energy-saving mode, normal working mode and high-power enhancement mode. Improve the stability of the atomization effect. By acquiring multimodal data in real time and making corresponding adjustments, the electronic cigarette can automatically optimize the atomizer power, airflow channel and working mode according to different temperature and humidity environments and user smoking conditions. This ensures that the e-liquid is fully atomized and produces a stable amount of smoke under various environmental conditions, avoiding fluctuations in the atomization effect caused by environmental changes or different user smoking habits; improving the user's taste experience, taking into account the impact of various factors such as temperature and humidity, smoking intensity and duration on the taste, and adjusting the atomizer power and airflow channel to make the smoke concentration, temperature and taste more in line with user needs. For example, in a low temperature environment, the power is appropriately increased to ensure that the e-liquid is fully atomized and the smoke tastes richer; in a high humidity environment, the airflow channel is adjusted to prevent water vapor from affecting the taste; the working mode of the atomizer is dynamically adjusted according to actual needs, and a low-power energy-saving mode is used when high-power output is not required, which can effectively reduce energy consumption and extend the battery life. This not only improves the endurance of electronic cigarettes, but also reduces energy waste, meeting the requirements of energy conservation and environmental protection; it enables electronic cigarettes to adapt to different environmental conditions and user smoking habits, improves the adaptability and versatility of the product, and can provide users with a better user experience compared to traditional electronic cigarettes, thereby enhancing the competitiveness of the product in the market.

[0020] In one embodiment of the present invention, obtaining multimodal data during atomization of an electronic cigarette includes: The humidity sensor and temperature sensor arranged at the air inlet end of the electronic cigarette detect the ambient humidity and ambient temperature; The user's inhalation action is detected by the microphone, the start time and the end time of inhalation are recorded, the inhalation duration is calculated, and the maximum air pressure change value during the inhalation process is detected at the same time, and the maximum air pressure change value indicates the inhalation intensity.

[0021] The working principle and effect of the above technical solution are as follows: environmental parameter detection, humidity sensor and temperature sensor are set at the air inlet end of the electronic cigarette, which can sense the humidity and temperature information of the surrounding environment in real time. The humidity sensor senses the change of water vapor content in the environment and converts it into an electrical signal output; the temperature sensor outputs an electrical signal corresponding to the ambient temperature based on the principle that temperature change causes its own physical properties (such as resistance value) to change. These electrical signals will be transmitted to the control system of the electronic cigarette for processing. The microphone is a sensor that can sense sound or pressure changes. In the use scenario of electronic cigarettes, when the user smokes, a certain airflow change will occur, and the pressure change caused by this airflow change will be detected by the microphone. From the time the microphone detects the pressure change, the system records the start time of smoking. When the pressure returns to normal, that is, when the user stops smoking, the end time is recorded. By subtracting the start time from the end time, the smoking time can be calculated. At the same time, during the entire smoking process, the microphone can also detect the maximum value of the pressure change, which is used to indicate the intensity of smoking. This is because a greater smoking intensity usually leads to a greater air pressure change, which causes the microphone to detect a greater pressure change value. Accurate environmental perception, through humidity sensors and temperature sensors to obtain real-time environmental humidity and temperature information, helps e-cigarettes to make intelligent adjustments according to different environmental conditions; accurate detection of users' puffing actions and recording of data such as puffing duration and puffing intensity can provide users with personalized usage analysis.

[0022] In one embodiment of the present invention, the comprehensive influencing factors of temperature and humidity are calculated based on multimodal data during the atomization process of electronic cigarette, including: The temperature and humidity comprehensive impact factor is calculated by the temperature and humidity comprehensive impact atomization effect evaluation model. Specifically, the temperature and humidity comprehensive impact atomization effect evaluation model is: ; in, represents the comprehensive influencing factor of temperature and humidity, Indicates the preset optimal working temperature of the electronic cigarette. Indicates the preset optimal working humidity of the electronic cigarette. It indicates the standard deviation of temperature effect, that is, the speed of change of the effect on the atomization effect of electronic cigarette when the ambient temperature deviates from the optimal working temperature. It represents the standard deviation of humidity influence, that is, the speed of change of the effect on the atomization effect of electronic cigarette when the ambient humidity deviates from the optimal working temperature.

[0023] The working principle and effect of the above technical solution are as follows: the optimal working temperature and the optimal working humidity are pre-set, representing the temperature and humidity conditions under which the electronic cigarette can achieve the best atomization effect under ideal conditions. And H= When the atomization effect reaches the best, the comprehensive influence factors of temperature and humidity are Get the maximum value. Because when the ambient temperature and humidity are at the optimal value, the physical properties of the e-liquid (such as viscosity, evaporation rate, etc.) and the working efficiency of the atomizer are in an ideal state, and there is no additional negative impact on the atomization effect. The standard deviation of temperature effect and the standard deviation of humidity effect measure the speed of change of the effect on the atomization effect of the electronic cigarette when the ambient temperature deviates from the optimal working temperature. The smaller it is, the temperature slightly deviates from the optimal value, and the impact on the atomization effect will increase rapidly; The larger the value, the more the temperature needs to deviate from the optimal value before it will have a more obvious impact on the atomization effect. Effect of humidity on Similar to the effect of temperature, the standard deviation of humidity describes the rate of change of the effect on the atomization effect when the ambient humidity deviates from the optimal working humidity. The comprehensive influence factor of temperature and humidity is calculated by the formula. Index part It is a comprehensive measure of the deviation of temperature and humidity from the optimal value. The square term is used to ensure that the deviation value, whether positive or negative, can be reflected as a negative impact on the atomization effect, and the greater the deviation, the more significant the impact. The whole formula is an exponential decay function. As the degree of deviation of temperature and humidity from the optimal value increases, The value of will gradually decrease, indicating that the negative impact of temperature and humidity on the atomization effect is gradually increasing. This model comprehensively considers the impact of temperature and humidity on the atomization effect. The effects of temperature and humidity are independent of each other but act together on the atomization process. By quantifying the deviations of temperature and humidity from the optimal values ​​respectively and adding them in the exponential part, the degree of comprehensive influence of temperature and humidity on the atomization effect can be accurately reflected. The model can more accurately evaluate the comprehensive impact of ambient temperature and humidity on the atomization effect of electronic cigarettes. By calculating the comprehensive influencing factor of temperature and humidity, you can intuitively understand the degree of influence on the atomization effect under the current temperature and humidity conditions. This helps the electronic cigarette to make adaptive adjustments according to the actual temperature and humidity conditions to ensure a stable atomization effect. Supports adaptive adjustment based on the calculated , electronic cigarettes can adjust the power of the atomizer, airflow channel and other parameters. For example, when When it is small, it means that the negative impact of temperature and humidity on the atomization effect is greater. At this time, the power of the atomizer can be appropriately increased to compensate for the problem of reduced smoke volume and worse taste caused by the adverse effects of temperature and humidity; or the airflow channel can be adjusted to optimize air circulation and improve the atomization environment. By accurately evaluating the impact of temperature and humidity and making adaptive adjustments, electronic cigarettes can provide relatively stable and good atomization effects under different temperature and humidity environments. This means that users can get a relatively consistent smoke volume and taste experience under various environmental conditions, which improves user satisfaction and loyalty to the product.

[0024] In one embodiment of the present invention, a puff intensity compensation factor is calculated based on multimodal data during atomization of an electronic cigarette, including: The suction intensity compensation factor is calculated by using a suction intensity compensation model. Specifically, the suction intensity compensation model is: ; in, Indicates the suction intensity compensation factor, Indicates the intensity of suction. Indicates the preset maximum suction intensity threshold.

[0025] The working principle and effect of the above technical solution are as follows: the suction intensity compensation model is designed to adjust the working state of the electronic cigarette atomizer according to the different suction intensity of the user to meet the diverse suction needs of the user. Different users have different smoking habits, and the suction intensity varies. Traditional electronic cigarettes may not be able to adapt to this difference well. By calculating the suction intensity compensation factor through the model, the parameters such as the atomizer power can be dynamically adjusted to ensure good atomization effect under different suction intensities. The suction intensity is characterized by detecting the maximum air pressure change value during the suction process. When the user smokes the electronic cigarette, the air pressure changes inside the electronic cigarette. The greater the suction intensity, the greater the air pressure change value. The preset maximum suction intensity threshold is a pre-set value, which represents the maximum reasonable suction intensity considered when designing the electronic cigarette. It is used as a reference standard to determine the upper limit of the suction intensity compensation factor to avoid over-compensation due to excessive suction intensity, damage to the electronic cigarette or unsafe conditions. The suction intensity compensation factor is the output result of the model, which is used to compensate for the impact of different suction intensities on the atomization effect. The value of will increase with the increase of the suction intensity, so that when the suction intensity is large, the power of the atomizer or other related parameters can be increased accordingly to produce more smoke to meet user needs. The model adopts the form of a logarithmic function, which has the characteristic of gradually slowing down the growth rate, which is in line with the actual situation. When the suction intensity is small, a slight increase in the suction intensity will lead to a more obvious increase in the compensation factor to ensure that even with light suction, enough smoke can be produced; and when the suction intensity approaches or reaches the maximum suction intensity threshold, the growth rate of the compensation factor will slow down to avoid over-compensation. The constant 1 ensures that even if the suction intensity is small, the compensation factor will increase. =0, the compensation factor also has a basic value, and no additional compensation is required at this time. To meet the diverse smoking needs, the smoking intensity of different users varies greatly. The model can dynamically adjust the working state of the atomizer according to the actual smoking intensity of the user. For users with greater smoking intensity, the compensation factor will increase, so that the atomizer outputs higher power and produces more smoke to meet their needs for rich smoke and strong taste; for users with less smoking intensity, the compensation factor is relatively small, and the atomizer output power is moderate to avoid excessive smoke causing waste or bad experience; By compensating for different smoking intensities, regardless of the user's smoking habits, a relatively stable and satisfactory atomization effect can be obtained when smoking electronic cigarettes. This reduces the difference in smoke volume and taste caused by different smoking intensities, and improves the consistency and satisfaction of the user's experience during use. The logarithmic function form adopted by the model can avoid excessive increase in power when the smoking intensity is large, thereby optimizing energy utilization efficiency while meeting user needs. Compared with simple linear compensation methods, logarithmic compensation can distribute energy more reasonably, extend the use time of electronic cigarette batteries, and reduce energy consumption costs; the inhalation intensity compensation model enables electronic cigarettes to better adapt to the inhalation habits of different users, enhancing the adaptability and versatility of the product. In market competition, products that can provide more personalized and higher-quality experiences are often more attractive and help improve the market competitiveness of products.

[0026] In one embodiment of the present invention, a correction factor for inhalation duration is calculated based on multimodal data during atomization of electronic cigarettes, including: The inhalation time correction factor is calculated by the inhalation time correction model. Specifically, the inhalation time correction model is: ; in, Indicates the correction factor for the duration of smoking, Indicates the preset minimum effective smoking time. It represents the preset maximum reasonable smoking time, and t represents the smoking time.

[0027] The working principle and effect of the above technical solution are as follows: The purpose of designing the inhalation time correction model is to reasonably adjust the working state of the electronic cigarette atomizer according to the time the user smokes the electronic cigarette. Different inhalation times have different effects on the consumption of e-liquid, the atomization effect and the user experience, so it is necessary to balance these effects through correction factors to ensure that good atomization effects and user experience can be achieved under various inhalation times. The inhalation time refers to the time from the beginning to the end of a user's inhalation action, which is calculated after the start time and the end time are recorded by the detection equipment such as the microphone. The preset minimum effective inhalation time is a pre-set time threshold, which represents the shortest inhalation time that can produce an effective atomization effect and smoke volume. If the inhalation time is less than the minimum effective inhalation time, the e-liquid may not be fully heated and sufficient smoke may not be generated, so the work of the atomizer needs to be adjusted accordingly. The preset maximum reasonable inhalation time is also a pre-set time threshold, which defines the upper limit of the reasonable duration of a single inhalation. Smoking for longer than the preset maximum reasonable smoking time may lead to excessive consumption of e-liquid, overheating of the atomizer, and poor taste, so corrections are also required. When the inhalation time is short, the ideal atomization effect may not be achieved. The correction factor is obtained by dividing the inhalation time by the minimum effective inhalation time, so that the correction factor is less than 1. This means that in this case, the power or other related parameters of the atomizer may be reduced accordingly to avoid unnecessary energy consumption and waste of e-liquid. When : In this range, the inhalation time is within a reasonable range, which can produce a good atomization effect and user experience. Therefore, the correction factor is , indicating that no additional correction is required for the normal working state of the atomizer. When When inhaling for too long, it may cause a series of problems, such as overheating of the atomizer and deterioration of the taste of the e-liquid. The correction factor is obtained by dividing the maximum reasonable inhalation time by the actual inhalation time, so that the correction factor is less than 1. This will cause the power or other parameters of the atomizer to be appropriately reduced to protect the atomizer and improve the taste. Optimizing the atomization effect and making corrections according to different inhalation times can ensure that a good atomization effect can be achieved under various inhalation times. For shorter inhalation times, excessive consumption of energy and e-liquid is avoided; for longer inhalation times, the problems of overheating of the atomizer and deterioration of the taste are prevented, thereby ensuring the stability of the smoke volume and taste; extending the service life of the atomizer, by reducing the power of the atomizer when the inhalation time is too long, reducing the long-term high-load operation of the atomizer, reducing the risk of overheating and damage of the atomizer, thereby extending the service life of the atomizer and reducing the user's cost of use. This enables electronic cigarettes to better adapt to the different smoking habits of users, and provide users with a stable and high-quality smoking experience regardless of the smoking time. It avoids problems such as insufficient smoke volume and poor taste caused by improper smoking time, and improves user satisfaction with the product. It saves energy and smoke oil. When the smoking time is too short or too long, by reasonably adjusting the working state of the atomizer, unnecessary energy consumption and smoke oil waste are reduced, and the utilization efficiency of energy and smoke oil is improved, which is in line with the concept of energy conservation and environmental protection.

[0028] In one embodiment of the present invention, the calculation of the optimal atomizer power according to the comprehensive influencing factor of temperature and humidity, the inhalation strength compensation factor and the inhalation time correction factor includes:

[0029] in, Indicates the optimal atomizer power, Indicates the basic atomizer power, represents the comprehensive influencing factor of temperature and humidity, Indicates the suction intensity compensation factor, Indicates the correction factor for smoking duration.

[0030] In one embodiment of the present invention, the method of adjusting the airflow channel of the electronic cigarette according to the multimodal data during the atomization process of the electronic cigarette comprises: The airflow channel adjustment coefficient is calculated based on the temperature and humidity in the multimodal data during the electronic cigarette atomization process. ; in, represents the airflow channel adjustment coefficient, Indicates the preset high humidity threshold, Indicates the maximum theoretical humidity value under the geographical area and climatic conditions of the electronic cigarette. Indicates the preset low temperature threshold, Indicates the maximum theoretical temperature value under the geographical area and climatic conditions where the electronic cigarette is located; Adjust the opening and closing degree of the airflow channel based on the airflow channel adjustment coefficient: ; in, Indicates the degree of opening and closing of the adjusted airflow channel. Indicates the opening and closing degree of the initial airflow channel.

[0031] The working principle and effect of the above technical solution are as follows: The temperature and humidity of the environment will significantly affect the atomization effect of the electronic cigarette. In a high humidity environment, too much water vapor will enter the inside of the electronic cigarette. On the one hand, it may dilute the smoke oil and make the smoke taste lighter; on the other hand, the water vapor will easily condense into water droplets inside when it encounters cold, affecting the normal operation of the atomizer and even damaging the electronic components. In a low temperature environment, the viscosity of the smoke oil will increase and the fluidity will deteriorate, resulting in increased difficulty in atomization, and problems such as reduced smoke volume and poor taste may occur. Therefore, it is necessary to adjust the airflow channel according to the temperature and humidity conditions of the environment to improve the atomization effect.

[0032] When the ambient humidity exceeds the preset high humidity threshold, the amount of water vapor entering the electronic cigarette needs to be reduced. At this time, the airflow channel adjustment coefficient is As humidity increases, The value of increases, This means that when the humidity is higher, the airflow channel adjustment coefficient is smaller, and the opening and closing degree of the airflow channel will be reduced accordingly, thereby reducing the amount of water vapor entering and reducing the negative impact of high humidity on the atomization effect. When the ambient temperature is lower than the preset low temperature threshold, in order to improve the atomization efficiency of the e-liquid, the air needs to stay in the e-cigarette longer to be fully heated. At this time, the airflow channel adjustment coefficient .because is a negative number. As the temperature decreases, The absolute value increases. The value of decreases. This reduces the opening and closing degree of the airflow channel, slows down the air flow rate, and increases the air residence time inside, which helps to improve the atomization effect of the smoke oil. When the ambient humidity does not exceed the high humidity threshold and the temperature is not lower than the low temperature threshold, it is considered that the current temperature and humidity environment has little effect on the atomization effect of the electronic cigarette, and there is no need to adjust the airflow channel, so the airflow channel adjustment coefficient is 1. After obtaining the airflow channel adjustment coefficient, the opening and closing degree of the airflow channel is adjusted through the formula. Improve the atomization effect. In a high humidity environment, reducing the opening and closing degree of the airflow channel can effectively reduce the entry of water vapor, avoid the dilution of the e-liquid and the generation of condensed water inside, ensure the taste and concentration of the smoke, and make the atomization effect more stable. In a low temperature environment, appropriately reducing the airflow channel can allow the air to fully heat the e-liquid, improve the atomization efficiency of the e-liquid, increase the amount of smoke, and improve the problem of poor atomization in a low temperature environment; protect electronic components, reduce the amount of water vapor entering in a high humidity environment, and reduce the risk of water vapor erosion on electronic components, such as preventing circuit short circuits and extending the service life of electronic components, thereby improving the reliability and stability of electronic cigarettes; improve user experience. By automatically adjusting the airflow channel according to the ambient temperature and humidity, users can obtain a more consistent and satisfactory smoking experience under different environmental conditions without the need for manual adjustment by the user, which increases the ease of use and comfort of the product; optimize energy utilization. In a normal environment where the airflow channel does not need to be adjusted, the initial state is maintained, unnecessary adjustment actions are avoided, the energy consumption used to adjust the airflow channel is reduced, and energy utilization efficiency is improved.

Indicates the preset low power threshold; when When using the normal working mode, the smoke volume and taste are guaranteed.
