[0002] Aerosols are gas dispersion systems consisting of solid or liquid particles suspended in a gaseous medium. Existing aerosol generators heat the aerosol-generating matrix through a built-in atomizer to produce aerosols that can be inhaled by the user.

[0003] Because the aerosol-generating matrix contains a certain proportion of harmful substances, these harmful substances easily mix with the aerosol during atomization and are inhaled by consumers. The amount of these harmful substances ingested is closely related to consumers' health; excessive inhalation can easily cause discomfort and, in severe cases, harm their health.

[0004] However, current common aerosol generators lack sufficient understanding and analysis of the mechanism of e-liquid atomization, making it impossible to analyze and measure the intake of harmful substances in the generated aerosol.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] This application provides a method for measuring the intake of harmful substances, which can be applied to an aerosol generator. The aerosol generator contains an aerosol generating matrix. Based on the physicochemical properties of the aerosol generating matrix, the enthalpy values ​​corresponding to different atomization processes can be calculated, and an atomization volume calculation model can be constructed. When a user's inhalation action is detected, the atomization volume generated by this inhalation action can be calculated according to the pre-established atomization volume calculation model, and the intake of harmful substances can be further calculated. The intake of harmful substances can be displayed and reminded through the aerosol generator to achieve health management. Furthermore, calculating and reminding of the intake of harmful substances directly through the aerosol generator eliminates the need for additional communication modules and other components, saving costs and providing greater convenience and speed.

[0047] Understandably, this method for measuring harmful substance intake can also be applied to terminal devices or servers. Specifically, the aerosol generator can be equipped with a communication module, which allows communication with the terminal device or server. The terminal device can acquire the physicochemical properties of the aerosol generating matrix, calculate the enthalpy corresponding to different atomization processes, and construct an atomization volume calculation model. When the aerosol generator detects a user's inhalation action, it can acquire the inhalation time and aerosol operating power and send them to the terminal device. Using the pre-constructed atomization volume calculation model in the terminal device, the atomization volume of this inhalation action is calculated, and the harmful substance intake during this inhalation action is calculated. This harmful substance intake is then sent to the aerosol generator for display, and a prompt message can be output when a preset threshold is exceeded. Calculating the atomization volume and harmful substance intake through the terminal device can save the calculation time of the aerosol generator and improve the calculation speed.

[0048] The communication module can be a Bluetooth module, a WIFI module, a 4G module, a 5G module, etc., to establish a communication connection with the terminal device or server.

[0049] In the embodiments of this application, the terminal device includes, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices.

[0050] In this embodiment of the application, the terminal device can also generate a chart of the user's intake of harmful substances, which can be sorted by time or number of suctions, so that the user can intuitively see their intake of harmful substances in a recent period of time, so as to reasonably arrange the suction time and number of suctions, and realize the function of health management.

[0051] Furthermore, the terminal device can also provide health management suggestions based on the user's intake of harmful substances over a period of time, such as suggesting the frequency of aspiration and the interval between aspirations, in order to provide scientific and healthy management advice.

[0052] In one embodiment, such as Figure 1 As shown, a method for measuring the intake of harmful substances is provided, the method comprising the following steps:

[0053] In step S110, initial atomization data is obtained, and the enthalpy values ​​corresponding to different stages in the atomization process of aerosol generation matrix are calculated based on the initial atomization data. Based on the enthalpy values ​​corresponding to different stages, an atomization amount calculation model is constructed.

[0054] In the embodiments of this application, the aerosol generating matrix can be divided into a solid aerosol generating matrix or a liquid aerosol generating matrix. The heating and atomization process of different forms of aerosol generating matrix can be divided into different stages. For example, the heating and atomization process of liquid aerosol generating matrix can be divided into a liquid phase heating stage, a phase change from liquid phase to gas phase, and a gas phase overheating stage.

[0055] Among them, see Figure 2-4 The heating stage of the liquid phase is as follows: the aerosol generating matrix is ​​heated from the liquid phase to the boiling point. Assuming that under calibration conditions, the aerosol generating matrix is ​​heated to the boiling point, for example, isobaric heating, and the ambient pressure is kept constant at 101325 Pa (1 atm). During this stage, the aerosol generating matrix in the liquid phase continues to heat up, and the absorbed heat energy is represented by the enthalpy value.

[0056] Specifically, the phase transition stage from liquid to gas phase is as follows: when the aerosol matrix is ​​at its boiling point, it changes from liquid to gas phase. Ignoring the expansion work of the gas phase, the absorption of heat energy leads to a change in internal energy, which can be represented by the phase transition enthalpy.

[0057] Specifically, the overheating stage of the gas phase is as follows: after the aerosol generating matrix transforms into the gas phase, it continues to absorb heat energy, causing the aerosol generating matrix that has transformed into the gas phase to overheat. The average temperature can be statistically represented as the temperature of the aerosol generating matrix that has transformed into the gas phase.

[0058] In the embodiments of this application, the different forms of aerosol generating matrix have different component contents and different contents of harmful substances. As one implementation method, the aerosol generating matrix can be composed of vegetable glycerin (PG), propylene glycol (VG) flavoring, nicotine and other components.

[0059] In this embodiment, the initial atomization data can specifically be the physicochemical properties of the aerosol generating matrix, such as the initial ambient temperature, boiling point temperature, average temperature during the gas phase superheating stage, liquid phase isobaric specific heat capacity, gas phase isobaric specific heat capacity, and phase change evaporation enthalpy corresponding to the aerosol generating matrix. Specifically, it can be determined based on the proportions of the components of the aerosol generating matrix, such as the ratio of PG and VG, or based on the type of aerosol generating matrix, such as liquid or solid aerosol generating matrix. It is understood that different types of aerosol generating matrices will yield different initial atomization data, which can be obtained through testing based on actual conditions.

[0060] In one embodiment of this application, the step of acquiring initial atomization data and calculating the enthalpy values ​​corresponding to different stages during the atomization process of the aerosol generation matrix based on the initial atomization data includes:

[0061] The initial ambient temperature, boiling point temperature, and average temperature of the gas phase superheating stage are obtained.

[0062] Obtain the liquid phase isobaric specific heat capacity, gas phase isobaric specific heat capacity, and phase change evaporation enthalpy corresponding to the aerosol generating matrix;

[0063] The enthalpy values ​​corresponding to the different stages are calculated based on the initial ambient temperature, boiling point temperature, average temperature of the gas phase superheating stage, liquid phase isobaric specific heat capacity, gas phase isobaric specific heat capacity, and phase change evaporation enthalpy of the aerosol medium.

[0064] Specifically, since the main components of this aerosol generating matrix are PG and VG, it can be simplified as a mixture of PG and VG. The PG / VG ratio not only affects the calculation of Δh but also the molar mass M of the aerosol generating matrix. This is because aerosol generating matrices composed of different PG / VG ratios exhibit different physicochemical properties of PG and VG. For example, the boiling point of PG is 187.3℃, while that of VG is 289℃; the enthalpy of vaporization of PG is 52.4 kJ / mol, while that of VG is 61 kJ / mol; and the molar mass of PG is 76.09 g / mol, while that of VG is 92.09 g / mol. Therefore, in actual calculations, the actual PG / VG ratio should be used.

[0065] Furthermore, based on the actual PG / VG ratio in the aerosol generating matrix, the physicochemical properties of the PG and VG, i.e., the initial atomization data, such as isobaric heat capacity (e.g., liquid phase isobaric specific heat capacity, gas phase isobaric specific heat capacity), boiling point, enthalpy of vaporization, and average temperature of the superheating stage, are determined. The enthalpy values ​​of the aerosol generating matrix in the liquid phase heating stage, the phase transition from liquid to gas phase, and the superheating stage of the gas phase are calculated respectively. Based on the functional or numerical relationship between the enthalpy values ​​corresponding to different stages and the atomization amount, an atomization amount calculation model is constructed.

[0066] Furthermore, based on the initial ambient temperature, boiling point temperature, average temperature during the superheating stage, liquid phase isobaric specific heat capacity, gas phase isobaric specific heat capacity, and phase change evaporation enthalpy of the aerosol medium, the enthalpy values ​​corresponding to the different stages are calculated, including:

[0067] Based on the initial ambient temperature, boiling point temperature, and specific heat capacity of the liquid phase at constant pressure, calculate the first enthalpy value corresponding to the liquid phase heating stage of the aerosol generating matrix;

[0068] Based on the boiling point temperature and the enthalpy of phase change evaporation, calculate the second enthalpy value corresponding to the liquid-to-gas phase stage of the aerosol generating matrix;

[0069] Based on the boiling point temperature, the average temperature of the gas phase superheating stage, and the specific heat capacity of the gas phase at constant pressure, the third enthalpy value corresponding to the gas phase superheating stage of the aerosol generating matrix is ​​calculated.

[0070] Specifically, the first enthalpy value h1 can be obtained using the following formula:

[0071]

[0072] The second enthalpy value h2 can be obtained using the following formula:

[0073] h2=Δ vap h(T1);

[0074] The third enthalpy value h3 can be obtained using the following formula:

[0075]

[0076] Where T1 represents the initial ambient temperature, T2 represents the boiling point temperature, T3 represents the average temperature during the superheating stage, and C p, C represents the specific heat capacity of a liquid phase at constant pressure. p, Δvaph represents the isobaric specific heat capacity of the gas phase, and Δvaph is the enthalpy of phase change evaporation.

[0077] In this embodiment of the application, the step of constructing an atomization quantity calculation model based on the enthalpy value includes:

[0078] The sum of the first enthalpy value, the second enthalpy value, and the third enthalpy value is calculated as the thermal energy value required to heat the aerosol generation matrix;

[0079] Based on the thermal energy value, a calculation model for the atomization amount is established.

[0080] Specifically, the thermal energy Δh required for the aerosol to generate the matrix is ​​expressed as:

[0081] Δh = h1 + h2 + h3;

[0082] Here, Δh represents the specific enthalpy required for a unit mass of aerosol to evaporate into the gas phase. Based on the numerical or functional relationship between Δh and the atomization rate, an atomization rate calculation model can be established, as shown below:

[0083] m = f(Δh);

[0084] In step S120, the suction time of a single suction action by the user and the operating power of the aerosol generator are obtained.

[0085] In this embodiment, the operating power can be pre-stored in the storage unit of the aerosol generator, and can be retrieved from the storage unit when it is necessary to calculate the intake of harmful substances. It is understood that the operating power of the aerosol generator varies depending on its operating mode; therefore, the corresponding operating power can be obtained based on the current operating mode of the aerosol generator, such as low-power heating mode or normal heating mode.

[0086] In this embodiment of the application, a single suction action of a user refers to any single suction action of the user. When the user's suction behavior is detected, the start time and end time of the user's suction action can be recorded, and then the suction time can be determined based on the start time and end time.

[0087] In step S130, the atomization amount is calculated based on the suction time, operating power, and atomization amount calculation model.

[0088] In this embodiment of the application, the atomization amount can be understood as the amount of aerosol released by the aerosol generator through the internal heating module when the user performs inhalation, by heating and atomizing the aerosol generating matrix inside the device.

[0089] In the embodiments of this application, the amount of atomization can vary depending on the inhalation time, inhalation intensity, operating mode, and operating power. For example, the amount of atomization released during long inhalations can be greater than that released during short inhalations, and the amount of atomization released during heavy inhalations can be greater than that released during light inhalations. The atomization amount calculation model constructed in this application can minimize the impact of factors such as inhalation intensity, and the calculated intake of harmful substances is highly accurate.

[0090] In this embodiment, based on a pre-established atomization calculation model, the specific enthalpy Δh required for a unit mass of aerosol generating matrix to evaporate into the gas phase is determined. If a unit mass of aerosol generating matrix is ​​represented as 1 mol of aerosol generating matrix, then the corresponding physical property parameters can all be measured in mol. If the molar mass of the aerosol generating matrix is ​​set to M, then the heat energy required for atomizing 1 mol of aerosol generating matrix is ​​Δh. Therefore, the heat energy ΔH required for atomizing an aerosol generating matrix of mass m can be expressed as:

[0091] ΔH=m / M*Δh

[0092] Assuming that the heat energy ΔH is entirely generated by battery heating, and the time of a single suction action is Δt, and the power is P, then the atomization amount can be expressed as:

[0093] m = ΔH * M / Δh = p * Δt * M / Δh

[0094] In step S140, the amount of harmful substances released in the atomized amount is calculated based on the atomization amount.

[0095] In the embodiments of this application, hazardous substances may include at least one of aldehydes, nitrogen compounds, olefins, nicotine, amines, cyanides, heavy metals, benzenes, arsenic, methylhydrazine, radioactive substances, phenolic compounds, and carbon monoxide.

[0096] In this embodiment, nicotine is used as an example. For instance, the proportion of nicotine in the aerosol generating matrix is ​​20mg, 30mg, or 35mg, which is 2%, 3%, or 3.5% by mass. Assuming this proportion is α, the relationship between the amount of nicotine released from the aerosol generating matrix and the heating energy can be expressed as follows:

[0097] m1=f(□H)*α

[0098] In this embodiment, during the aerosol generation process, harmful substances contained in the aerosol medium are generated along with the generated aerosol. It is understood that the generated aerosol contains harmful substances. Therefore, the above calculation method can effectively calculate the amount of harmful substances released from the generated aerosol matrix. Since the generated aerosol usually enters the human body, and the harmful substances within it can have adverse effects, calculating the amount of harmful substances released during atomization can draw consumers' attention and encourage more rational use of aerosol generators.

[0099] In the embodiments of this application, since the types of aerosol generating matrices are different, the composition and content of harmful substances contained in the generated aerosols are also different. Therefore, when performing calculations, the mass ratio of different harmful substances can be determined according to the type of aerosol generating matrices, and then the release amount of different harmful substances can be calculated in the above manner.

[0100] In step S150, the amount of harmful substance ingested by the user in a single inhalation action is calculated based on the amount of harmful substance released.

[0101] In this embodiment, when a user performs inhalation, the aerosol generated during inhalation is not completely absorbed by the human body; a portion is exhaled into the environment as an aerosol. Therefore, the proportion of harmful substances ingested by the human body can be calculated. Taking nicotine as an example, its ingestion proportion is β. This ingestion proportion can be obtained through experiments using multiple samples. The relationship between the amount of harmful substances released and the heating energy can be:

[0102] m nicotine =f(ΔH)*α*β

[0103] Furthermore, based on the relationship between the release of harmful substances and the heating energy, the content of harmful substances ingested by a user in a single inhalation action can be calculated. The amount of harmful substances ingested by the user in a single inhalation action is then expressed as:

[0104] mnicotine=(P*Δt*M / Δh)*α*β;

[0105] Furthermore, considering the heat loss Q that occurs during the heat transfer stage, the intake of harmful substances can be further expressed as:

[0106] mnicotine=[(P*Δt-Q)*M / Δh]*α*β;

[0107] The heat loss may include: heat loss caused by matrix heat conduction from the atomizing core to the aerosol in the atomizing chamber, and heat loss caused by convective heat transfer from the atomizing core to the incoming air.

[0108] In one embodiment of this application, after calculating the amount of harmful substance ingested by the user in a single suction action, the process includes:

[0109] When the intake exceeds a first preset threshold, a first prompt message is output, and the operating power of the aerosol generator is adjusted.

[0110] In this embodiment of the application, the first preset threshold may specifically be the upper limit of the intake of the harmful substance in a single suction action. If the upper limit is exceeded, it is easy to cause great harm to the user. If it is lower than the upper limit, it can be tolerated by the user.

[0111] The first preset threshold can be set according to the type of aerosol generating matrix, the power of the aerosol generating device, and the tolerance of different users to harmful substances.

[0112] For example, users who use aerosol generators frequently and for extended periods have a higher tolerance for ingested aerosols. If the same upper limit is set for these users as for ordinary users, they may not be able to adapt and could easily experience physical discomfort. Therefore, the upper limit can be appropriately increased for such users, and they can be reminded each time they use the aerosol generator to guide them to gradually lower the upper limit, thereby achieving the purpose of health management.

[0113] The first preset threshold can be user-defined or automatically set by the system, and can be manually or automatically adjusted according to the user's needs.

[0114] In this embodiment, the first prompt information can be one or more combinations of text, sound, graphics, and light. For example, the prompt information can be displayed on a pre-set display screen on the aerosol generator. For instance, it can directly display a dynamic value of the amount of harmful substance ingested, which can gradually change with the user's inhalation time. Alternatively, it can be prompted using vibration, ringtone, or voice. The light information can be provided by pre-setting LED beads on the aerosol generator. When the value is less than the first preset threshold, it can be displayed in green; when it is equal to the first preset threshold, it can be displayed in yellow; and when it exceeds the first preset threshold, it can be displayed in red. Flashing can also be added to improve the prompting effect.

[0115] Furthermore, in order to remind users before they ingest harmful substances, the time of each aspiration action, the operating power of the aerosol generator, and the aspiration intensity can be calculated based on the first preset threshold. When the user performs the aspiration action, the aspiration time and aspiration intensity can be detected in real time. When the aspiration time or aspiration intensity exceeds the first preset threshold, a prompt message is output to remind the user to stop the aspiration action.

[0116] In one embodiment of this application, after calculating the amount of harmful substance ingested by the user in a single suction action, the process includes:

[0117] The amount of harmful substances ingested by the user during each suction action within a preset time range is calculated and statistically analyzed.

[0118] When the amount of harmful substances ingested exceeds the second preset threshold, a second prompt message is output, and the aerosol generator is locked.

[0119] The preset time range can be 1 day, 1 week, 1 month, etc., and can be set according to the actual situation.

[0120] The second preset threshold can be based on the upper limit of a user's intake of harmful substances within a preset time range, such as the intake of harmful substances in a day, a week, or a month. If the intake exceeds this upper limit, it is likely to cause significant harm to the user; if it is below this upper limit, it is within the user's normal tolerance.

[0121] The second preset threshold can be set according to the type of aerosol generating matrix, the power of the aerosol generating device, and the tolerance of different users to harmful substances. For example, the average value of the user's historical intake of harmful substances over multiple consecutive preset time ranges can be used as the second preset threshold. For example, the daily intake of harmful substances over a continuous week can be calculated and its average value can be calculated.

[0122] For example, users who use aerosol generators frequently and for extended periods have a higher tolerance for ingested aerosols. If the same upper limit is set for these users as for ordinary users, they may not be able to adapt and could easily experience physical discomfort. Therefore, the upper limit can be appropriately increased for such users, and they can be reminded each time they use the aerosol generator to guide them to gradually lower the upper limit, thereby achieving the purpose of health management.

[0123] In this embodiment, the content of harmful substances ingested by the user during each aspiration session within a preset time range is calculated and statistically analyzed. For example, the intake of harmful substances within a day can be statistically analyzed. When the statistically analyzed intake of harmful substances exceeds a second preset threshold, a prompt message can be output, and the aerosol generator can be locked until the next day. This is to prevent the user from excessively ingesting harmful substances and causing harm to their health.

[0124] In this embodiment, the first prompt information can be one or more combinations of text, sound, graphics, and light. For example, the prompt information can be displayed on a pre-set display screen on the aerosol generator. For instance, it can directly display a dynamic value of the amount of harmful substance ingested, which can gradually change with the user's inhalation time. Alternatively, it can be prompted using vibration, ringtone, or voice. The light information can be provided by pre-setting LED beads on the aerosol generator. When the value is less than the first preset threshold, it can be displayed in green; when it is equal to the first preset threshold, it can be displayed in yellow; and when it exceeds the first preset threshold, it can be displayed in red. Flashing can also be added to improve the prompting effect.

[0125] In this embodiment of the application, when it is detected that the amount of harmful substance ingested by a user in a single inhalation action exceeds the first preset threshold, or when the amount of substance ingested within a preset time range exceeds the second preset threshold, suggestion information can be output. For example, the harm of excessive inhalation of the harmful substance can be listed, and reasonable inhalation suggestions can be given, such as the number of inhalations and the duration of inhalation, so that users can better pay attention to their own health and reasonably arrange their inhalation behavior.
