Description

Technical Field

[0002] Since its advent in the early 21st century, e-cigarettes have experienced rapid development and popularization. Initially, as a substitute for traditional tobacco, e-cigarettes focused on reducing the inhalation of harmful substances and attracted a large number of smokers. In recent years, e-cigarette technology has continued to innovate, and product types and functions have continued to enrich. In addition to the traditional smoking substitute function, it has also added a variety of taste adjustments, intelligent control and personalized experience features.

[0003] Existing e-cigarette technology usually relies on static taste settings or preset smoking modes. Fixed smoking modes cannot adapt to the different needs of users. Each user's smoking habits, taste preferences and physiological reactions are different, resulting in the inability of e-cigarette parameters such as smoke concentration, smoke flow rate and temperature to accurately match user needs, and cannot be adjusted during the user's smoking process. Once the user's inhalation intensity or inhalation time changes, the output characteristics of the e-cigarette may become unsuitable. Therefore, how to achieve segmented adjustment of regional smoke concentration within the e-cigarette to improve the adaptability of the user's e-cigarette smoking taste is a difficult problem faced by the industry.

[0047] In order to better understand the technical solution of the present application, the technical solution of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] refer to Figure 1 , which is an exemplary flow chart of an electronic cigarette taste intelligent control method according to some embodiments of the present application, and the electronic cigarette taste intelligent control method mainly includes the following steps:

[0049] In step 101, the flow speed of smoke in the electronic cigarette and the amount of smoke in each smoke area are monitored when the user smokes.

[0050] It should be noted that, in the present application, the amount of smoke refers to the number of smoke particles in each smoke area inside the electronic cigarette; the smoke flow rate refers to the amount of smoke flowing in the internal pipe of the electronic cigarette every 1ms; a microcomputer electrical current sensor is used to monitor the smoke flow rate in the electronic cigarette and the amount of smoke in each smoke area; in specific implementation, when a user uses an electronic cigarette to smoke, a microcomputer electrical current sensor can be used to monitor the smoke flow rate in the electronic cigarette, and at the same time, the inside of the electronic cigarette is divided into multiple smoke areas according to the internal structure of the electronic cigarette, the smoke in each smoke area is controlled by an electronic airflow valve, and the microcomputer electrical current sensor can be used to monitor the amount of smoke in each smoke area.

[0051] In some embodiments, reference Figure 2 As described, the figure is a block diagram of the electronic cigarette control circuit shown in some embodiments of the present application, which shows in detail the connection and interaction between the various components inside the electronic cigarette. First, the airflow sensor (marked as the airflow sensor (SEN)) and the heating wire (marked as the heating wire (AT)) are two key parts of the electronic cigarette, where SEN means sensor, AT means atomizer, the airflow sensor triggers the smoking detection module by detecting the user's inhalation action, and the heating wire is the component that generates smoke, and the status information of these two components is transmitted to the control module.

[0052] The control module is the core module of the electronic cigarette. The control module receives signals from the smoking detection module, as well as status information from the open circuit detection module and the short circuit detection module. The open circuit detection module and the short circuit detection module respectively monitor the integrity of the circuit to ensure that no open circuit or short circuit occurs, which is crucial to the safe operation of the electronic cigarette. The control module decides whether to activate the drive module based on this information, and then controls the working status of the heating wire.

[0053] The driver module receives the command from the control module and controls the heating wire to produce smoke. At the same time, the charging module is responsible for managing the battery charging process of the electronic cigarette to ensure that the power supply (VDD) has sufficient power supply; the display module provides the user with feedback on the working status of the electronic cigarette through the light-emitting diode (LED) light, such as: battery power, smoking status, etc. The central console completes the circuit closure through the power supply (VDD) and ground (GND), ensuring that the electronic cigarette can work normally, ensuring the intelligence and automation of the electronic cigarette, and improving the user experience.

[0054] In step 102, the user's smoking process is divided into different inhalation stages based on the periodic characteristics of the flow speed of smoke in the electronic cigarette.

[0055] In some embodiments, dividing the user's smoking process into different inhalation stages based on the periodic characteristics of the smoke flow speed in the electronic cigarette can be achieved by the following steps:

[0056] Obtaining the periodic characteristics of the flow velocity of smoke in the electronic cigarette;

[0057] Extract multiple stage features of the smoke flow speed during the user's smoking process from the periodic features of the smoke flow speed;

[0058] The smoke flow speed during the user's smoking process is divided into stages based on the characteristics of each stage to obtain different inhalation stages.

[0059] It should be noted that, in the present application, the inhalation stage refers to the stage in which the smoke flow speed has the same changing law during the user's smoking process; the periodic characteristics reflect the repeated change pattern of the airflow during the user's smoking process; the stage characteristics describe the relationship characteristics between the airflow parameters and the user behavior at different inhalation stages.

[0060] In specific implementation, first, all smoke flow speeds monitored in a preset time period are obtained, and a periodic analysis algorithm (for example, Fourier transform algorithm) can be used to extract the periodic change law of all smoke flow speeds, so that the extracted periodic change law is used as the periodic feature of the smoke flow speed; then, the most recent smoke flow speed cycle can be selected through the periodic feature, so that each smoke flow speed in the smoke flow speed cycle that is maintained for more than 1s is used as a stage feature, and multiple stage features of the smoke flow speed during the user's smoking process can be obtained; finally, the time point when the smoke flow speed changes in each stage feature is used as a stage division node, and the smoke flow speed during the user's smoking process is divided into different inhalation stages using the stage division node.

[0061] It should be noted that, in the present application, the inhalation characteristic refers to the airflow characteristic of the user during the inhalation process. For each inhalation stage, an airflow sensor at the mouthpiece of the electronic cigarette can be used to monitor the user's inhalation volume every 10ms during the inhalation stage, so that the average of all inhalation volumes is used as the inhalation characteristic of the user during the inhalation stage. The inhalation characteristics of the user in each inhalation stage can be obtained in the above manner.

[0062] In step 103, the concentration gradient difference of the hot air smoke in the electronic cigarette between adjacent inhalation stages is determined by the inhalation characteristics and smoke volume of the user in each inhalation stage, and the concentration distribution characteristics of the hot air smoke in the electronic cigarette are determined by all the concentration gradient differences and the temperature differences between each smoke area.

[0063] In some embodiments, the following steps may be used to determine the concentration gradient difference of the hot air smoke in the electronic cigarette between adjacent inhalation stages based on the inhalation characteristics and smoke volume of the user in each inhalation stage:

[0064] For each inhalation stage, the temperature difference between the inside of the electronic cigarette and the outside environment during the inhalation stage is obtained from the temperature difference between the inside of the electronic cigarette and the outside environment;

[0065] The characteristic difference between the user's inhalation characteristics between the inhalation stage and the next inhalation stage is combined with the smoke volume to perform stage simulation, and obtain the simulated smoke volume of smoke particles inhaled by the user in the inhalation stage;

[0066] The concentration gradient difference of the hot air smoke in the electronic cigarette between the inhalation stage and the next inhalation stage is determined by the simulated smoke volume and the temperature difference value, and then the concentration gradient difference of the hot air smoke in the electronic cigarette between adjacent inhalation stages is obtained.

[0067] It should be noted that, in the present application, the concentration gradient difference is a characteristic that reflects the difference in hot air smoke during the inhalation stage; the temperature difference value indicates the temperature difference between the inside of the electronic cigarette and the external environment during the inhalation stage; the simulated smoke volume indicates the number of smoke particles at the smoking port of the electronic cigarette during the inhalation stage; the temperature difference indicates the temperature difference between the inside of the electronic cigarette and the external environment. For each inhalation stage, a temperature sensor can be used to measure the temperature values ​​of the inside of the electronic cigarette and the external environment, and the absolute value of the difference between the two temperature values ​​is used as the temperature difference value within the inhalation stage. The temperature difference value within each inhalation stage can be obtained in the above manner, and the set of all temperature difference values ​​can be used as the temperature difference between the inside of the electronic cigarette and the external environment.

[0068] In specific implementation, first, for each inhalation stage, the temperature difference between the inside of the electronic cigarette and the outside environment in the inhalation stage is obtained from the temperature difference between the inside of the electronic cigarette and the outside environment; then, the cosine similarity between the inhalation characteristics of the user between the inhalation stage and the next inhalation stage is used as the feature difference, and the feature difference is combined with the smoke volume to construct a simulation environment of the user in the inhalation stage. The simulation environment is used to perform a large number of simulation experiments on the process of the user inhaling smoke in the inhalation stage, and the number of smoke particles inhaled by the user in each simulation is obtained as the smoke particle volume, and the average of all smoke particle volumes can be used as the simulated smoke volume of the smoke particles inhaled by the user in the inhalation stage. In other embodiments, in order to improve the taste adjustment efficiency of the electronic cigarette, simulation training can be performed in advance for various user inhalation characteristics and user smoking processes under smoke concentrations to obtain various user inhalation characteristics and smoke concentrations in advance. Smoke particles inhaled by the user under smoke concentrations, thereby improving the taste adjustment efficiency of the electronic cigarette; finally, the product of the simulated smoke volume and the temperature difference can be used as the difference in the concentration gradient of the hot air smoke in the electronic cigarette between the inhalation stage and the next inhalation stage. The concentration gradient difference of the hot air smoke in the electronic cigarette between adjacent inhalation stages can be obtained in the above manner.

[0069] It should be noted that the temperature difference indicates the temperature difference between various smoke areas in the electronic cigarette, and a temperature sensor can be used to measure and calculate the temperature difference between adjacent smoke areas in the electronic cigarette as the temperature difference between various smoke areas.

[0070] In some embodiments, the following steps may be used to determine the concentration distribution characteristics of the hot air smoke in the electronic cigarette through all the concentration gradient differences and the temperature differences between the various smoke regions:

[0071] For each smoke region within the electronic cigarette, the regional smoke concentration of the smoke region is extracted from all concentration gradient differences;

[0072] Obtain the pipe temperature difference of the smoke area from the temperature difference between each smoke area;

[0073] The amount of hot air smoke in the smoke area is determined by the temperature difference of the pipe and the smoke concentration of the area, and then the amount of hot air smoke in each smoke area in the electronic cigarette is obtained;

[0074] The concentration distribution characteristics of the hot air smoke in the electronic cigarette are determined based on all the hot air smoke amounts.

[0075] It should be noted that, in the present application, the concentration distribution characteristics reflect the distribution of hot air smoke in different smoke areas within the electronic cigarette; the regional smoke concentration indicates the reaction force exerted on the hot air smoke when it flows through the internal pipe of the electronic cigarette; the pipe temperature difference indicates the temperature difference between different smoke areas in the airflow pipe inside the electronic cigarette; the hot air smoke volume indicates the smoke volume in the smoke area of ​​the electronic cigarette under current conditions.

[0076] In specific implementation, first, for each smoke area in the electronic cigarette, the regional smoke concentration of the smoke area is obtained from all concentration gradient differences; secondly, the average of two values ​​corresponding to the temperature difference in the smoke area can be used as the pipe temperature difference in the smoke area; then, the heat transfer formula (for example: heat convection formula) and fluid mechanics equation (for example: Bernoulli equation) can be used to construct a smoke volume estimation model, and the pipe temperature difference is used as the heat source term in the heat transfer formula in the estimation model, and the regional smoke concentration is used as the boundary condition in the heat transfer formula in the estimation model. The estimation model is used to estimate the smoke volume in the smoke area, and the estimated smoke volume can be used as the hot air smoke volume in the smoke area. The hot air smoke volume in each smoke area can be obtained in the above manner; finally, all hot air smoke volumes can be arranged according to the spatial position of the smoke area as the concentration distribution characteristics of the hot air smoke in the electronic cigarette.

[0077] It should be noted that the smoke volume estimation model is based on the basic principles of heat transfer and fluid mechanics, combined with the airflow and heat transfer process inside the electronic cigarette to estimate the smoke volume in each smoke area. The estimation model uses the heat transfer formula to simulate the transfer of heat energy in the airflow. Taking into account the temperature change when the airflow flows inside the electronic cigarette, the temperature difference acts as a heat source term in the heat transfer equation. At the same time, the fluid mechanics equation is combined to describe the resistance generated by the pressure and velocity changes in the airflow in the pipeline. These resistances are introduced into the model as boundary conditions. The combined use of the heat transfer formula and the fluid mechanics equation can be used to estimate the number of smoke particles in each smoke area, that is, the hot air smoke volume. The hot air smoke volume can effectively reflect the smoke generation situation in each area, thereby providing a basis for adjusting and optimizing the smoke concentration, airflow characteristics, etc., and ultimately improving the user's smoking taste experience.

[0078] In step 104, the smoke concentration at the mouth of the electronic cigarette is predicted based on the concentration distribution characteristics and the instantaneous evaporation amount of the atomized liquid in the electronic cigarette to obtain a predicted value of the smoke concentration inhaled by the user.

[0079] In some embodiments, the smoke concentration at the mouth of the electronic cigarette is predicted based on the concentration distribution characteristics and the instantaneous evaporation amount of the atomized liquid in the electronic cigarette to obtain a predicted value of the smoke concentration inhaled by the user. Figure 3The figure is a schematic diagram of a process for determining a predicted value of smoke concentration in some embodiments of the present application. In this embodiment, determining a predicted value of smoke concentration can be achieved by using the following steps:

[0080] In step 1041, the instantaneous smoke characteristics in the electronic cigarette after the user inhales are determined by the instantaneous evaporation amount of the atomized liquid in the electronic cigarette;

[0081] In step 1042, the instantaneous smoke feature and the concentration distribution feature are fused to obtain the smoke concentration output by the electronic cigarette;

[0082] In step 1043, the predicted value of the smoke concentration inhaled by the user is calculated based on the smoke concentration output by the electronic cigarette.

[0083] It should be noted that, in the present application, the predicted value of smoke concentration indicates the number of smoke particles output by the electronic cigarette per second; the instantaneous smoke characteristic indicates the instantaneous output of the electronic cigarette atomizer liquid evaporating and forming smoke in an instantaneous period; the instantaneous evaporation amount indicates the volume of the atomizer liquid in the electronic cigarette converted into smoke in an instantaneous period.

[0084] In specific implementation, first, 10ms is taken as an instantaneous period, and a flow sensor is used to monitor the volume of atomized liquid in the electronic cigarette after each instantaneous period after the user inhales. For each instantaneous period, the difference between the volume of atomized liquid after the instantaneous period and the volume of atomized liquid before the instantaneous period is taken as the instantaneous evaporation amount of the atomized liquid in the electronic cigarette in the instantaneous period. The instantaneous evaporation amount in each instantaneous period can be obtained by the above method, and the result of dividing the definite integral of all instantaneous evaporation amounts with respect to the instantaneous period by the user's inhalation time (seconds) can be taken as the instantaneous smoke feature in the electronic cigarette after the user inhales; then, the ratio of the hot air smoke volume in the smoke area corresponding to the electronic cigarette output port in the concentration distribution feature to the sum of all hot air smoke volumes is calculated as the smoke proportion in feature fusion, and the product of the instantaneous smoke feature and the smoke proportion can be taken as the smoke concentration output by the electronic cigarette; finally, the smoke dissipation ratio of the electronic cigarette is obtained from the central console of the electronic cigarette, so that the result of subtracting the product of the smoke concentration and the smoke dissipation ratio from the smoke concentration can be taken as the predicted value of the smoke concentration inhaled by the user.

[0085] In step 105, when the predicted smoke concentration value is not within the concentration range preset by the user, the atomizer in the electronic cigarette is used to adjust the adaptive temperature of the heated atomized liquid in each inhalation stage during the user's smoking process.

[0086] In some embodiments, when the predicted smoke concentration value is not within the concentration range preset by the user, the atomizer in the electronic cigarette is used to adjust the adaptive temperature of the heated atomized liquid in each inhalation stage during the user's smoking process, and the atomizer is a smoke oil guide wire atomizer based on a cotton guide wire; in specific implementation, when the predicted smoke concentration value is within the concentration range preset by the user, the electronic cigarette does not need to be adjusted and continues to maintain the current state. When the predicted smoke concentration value is not within the concentration range preset by the user, the adaptive temperature of the heated atomized liquid in each inhalation stage during the user's smoking process is controlled by adjusting the atomization temperature of the atomizer. After each adjustment, the predicted smoke concentration of the electronic cigarette inhaled by the user is calculated using the above method until the predicted smoke concentration value is within the concentration range preset by the user.

[0087] In addition, in another aspect of the present application, in some embodiments, the present application provides an electronic cigarette taste intelligent control system, referring to Figure 4 , which is a schematic diagram of the structure of an electronic cigarette taste intelligent control system according to some embodiments of the present application, and the electronic cigarette taste intelligent control system includes: a monitoring module 201, a processing module 202 and an execution module 203, which are respectively described as follows:

[0088] Monitoring module 201, in this application, the monitoring module 201 is mainly used to monitor the flow speed of smoke in the electronic cigarette and the amount of smoke in each smoke area when the user smokes;

[0089] Processing module 202, in the present application, the processing module 202 is used to divide the user's smoking process into different inhalation stages based on the periodic characteristics of the smoke flow speed in the electronic cigarette;

[0090] It should be noted that the processing module 202 is also used to determine the concentration gradient difference of the hot air smoke in the electronic cigarette between adjacent inhalation stages through the inhalation characteristics and smoke volume of the user in each inhalation stage, and determine the concentration distribution characteristics of the hot air smoke in the electronic cigarette through all the concentration gradient differences and the temperature differences between each smoke area;

[0091] In addition, it should be noted that the processing module 202 is also used to predict the smoke concentration at the mouth of the electronic cigarette according to the concentration distribution characteristics and the instantaneous evaporation amount of the atomized liquid in the electronic cigarette, so as to obtain a predicted value of the smoke concentration inhaled by the user;

[0092] Execution module 203, in the present application, is mainly used to use the atomizer in the electronic cigarette to adjust the adaptive temperature of the heated atomized liquid in each inhalation stage during the user's smoking process when the predicted smoke concentration value is not within the concentration range preset by the user.
