[0083] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0084] Reference Figure 1 As shown, a new method for detecting the content of active ingredients in electronic cigarette oil includes:

[0085] Obtaining at least one component substance in the electronic cigarette oil, screening at least one effective substance from the at least one component substance, and determining a reaction substance for effective substance detection;

[0086] Obtain the base heat generated during the complete reaction of unit mass of effective substances;

[0087] Obtain at least one sample from the same batch of electronic cigarette liquid to obtain the mass of the single sample;

[0088] Obtaining the reaction conditions of the effective substances in the sampled sample, wherein the reaction conditions include the amount of the reaction substances used and the external environment temperature during the reaction;

[0089] The sample is divided to obtain at least one detection sample droplet, the masses of the detection sample droplets are all consistent, and the masses of the detection sample droplets are all less than a preset value;

[0090] The test sample droplets are evenly arranged in the test box, a heat insulation layer is arranged on the surface of the test box, and a heating point is arranged on the surface of the heat insulation layer;

[0091] Monitor the temperature inside the test box in real time, and adjust the temperature of the insulation layer according to the real-time monitoring results;

[0092] Reacting at least one test sample droplet using the reaction conditions for the effective substance reaction;

[0093] Obtaining the initial temperature of the reaction in the detection box;

[0094] During the reaction, an infrared scanning image in the detection box is obtained, and the real-time reaction temperature in the detection box is calculated based on the infrared scanning image;

[0095] During the reaction process, the maximum real-time reaction temperature is obtained as the final reaction temperature, and the mass of the effective substance in the sample is calculated based on the final reaction temperature and the initial reaction temperature;

[0096] According to the mass of the effective substance in the sampled sample, the preliminary content of the effective substance is obtained, and the content of the effective substance in the electronic cigarette oil is obtained based on the content of the effective substance in at least one sampled sample.

[0097] When measuring heat, the temperature generated by the reaction is mainly measured. However, since the temperature in the reaction space will dissipate, this will cause errors in the measurement results. Therefore, this error needs to be avoided. In this solution, the temperature of the insulation layer is adjusted according to the real-time monitoring results. In this way, it can be ensured that the temperature in the detection box is not affected by the external ambient temperature, thereby improving the measurement accuracy.

[0098] Furthermore, when performing the measurement, a plurality of sampling samples are used for each effective substance and the measurement results are averaged, thereby avoiding the error of a single measurement.

[0099] Reference Figure 2 As shown, obtaining at least one component substance in the electronic cigarette oil includes the following steps:

[0100] The constituent substance is one of nicotine, heavy metals, volatile organic compounds, hazardous substances, microorganisms and prohibited substances;

[0101] Heavy metals consist of lead, cadmium, mercury and arsenic, harmful substances consist of formaldehyde and acetaldehyde, and banned substances consist of diacetyl and ethylene glycol.

[0102] E-cigarette oil is composed of a variety of substances, but not all substances will affect the quality of e-cigarette oil. Therefore, it is necessary to screen the constituent substances, and the screening depends on the usage experience of the sample evaluators. If one of the constituent substances is missing in each component set, then when the taste is not good, it means that the missing constituent substance is necessary and is therefore an effective substance. At the same time, in order to enhance the accuracy of the screening, the reliability of the results can be enhanced by increasing the number of sample evaluators.

[0103] Reference Figure 3 As shown, screening at least one effective substance from at least one constituent substance and determining a reaction substance for effective substance detection includes the following steps:

[0104] At least one component substance set is formed, the component substance sets are different from each other, the component substance set lacks at least one of the component substances, and the component substance lacking in the component substance set is used as the target component substance;

[0105] The elements in the set of constituent substances are used to form the e-liquid to be tested, and the appearance ratio of the same constituent substances in each e-liquid to be tested is consistent;

[0106] Using sample testers to screen out e-liquids with unqualified taste from the e-liquids to be tested, and summarizing the target constituent substances corresponding to all e-liquids with unqualified taste to obtain at least one effective substance;

[0107] A substance that reacts with only one of the at least one effective substance is used as a reactive substance for the effective substance.

[0108] Reference Figure 4 As shown, obtaining the reference heat generated during the complete reaction of unit mass of effective substances includes the following steps:

[0109] Dividing the effective substance of unit mass to obtain at least one test unit particle, the mass of the test unit particles are all consistent, and the mass of the test unit particles are all less than a preset value;

[0110] The test unit particles are evenly arranged in the test box, a heat insulation layer is arranged on the surface of the test box, and a heating point is arranged on the surface of the heat insulation layer;

[0111] Monitor the temperature inside the test box in real time, and adjust the temperature of the insulation layer according to the real-time monitoring results;

[0112] reacting at least one test unit particle using the reaction conditions for the reaction of the effective substance;

[0113] Obtaining the initial temperature of the reaction in the detection box;

[0114] When reacting, an infrared detection image in the detection box is obtained, and the real-time internal temperature in the detection box is calculated based on the infrared detection image;

[0115] During the reaction, the maximum real-time internal temperature is obtained as the terminal reaction temperature;

[0116] According to the first heat formula, the base heat generation heat is calculated;

[0117] The first calorie formula is as follows:

[0118] Q = cmΔt,

[0119] Among them, Q is the reference heat generation, c is the specific heat capacity of air, m is the mass of air in the detection box, and Δt is the difference between the terminal reaction temperature and the initial reaction temperature.

[0120] The reference heat generation heat corresponds to the effective substance, which is mainly used to determine the mass of the effective substance in the sample. Since the heat of complete reaction of the effective substance per unit mass with the corresponding reaction substance is fixed, the highest temperature point is taken as the terminal reaction temperature during the reaction. This is because after the complete reaction, the temperature will gradually decrease due to the lack of further reaction. When the reaction is not complete, the temperature will continue to rise due to the continuous heat release of the reaction. Therefore, when the reaction is complete, the temperature must be the highest point in the reaction process.

[0121] The reaction of effective substances is usually an exothermic reaction, so only the heat release is considered. However, due to different parameter settings of the e-cigarette oil, the reaction of some effective substances may be an endothermic reaction. In this case, the heat release in this scheme can be adjusted to endothermic, or the absorbed heat can be treated as a negative number.

[0122] Reference Figure 5 As shown, according to the real-time monitoring results, adjusting the temperature of the insulation layer includes the following steps:

[0123] According to the real-time monitoring results, the real-time temperature inside the detection box and the real-time temperature outside the detection box are obtained;

[0124] Obtain a temperature value range for the test, evenly divide the temperature value range for the test, and obtain at least one temperature collection point;

[0125] Randomly combine at least one temperature collection point into a binary array to obtain at least one temperature combination;

[0126] Under the condition that the detection box satisfies the temperature combination, the characteristic temperature of the detection box surface is obtained. When the detection box surface temperature is equal to the characteristic temperature, the temperature inside the detection box remains unchanged. The condition that the detection box satisfies the temperature combination means that: the temperature inside the detection box is equal to the value of the first temperature collection point in the temperature combination, and the temperature outside the detection box is equal to the value of the second temperature collection point in the temperature combination;

[0127] Pair and fit the temperature combination with the characteristic temperature to obtain a temperature fitting function, wherein the temperature combination is an independent variable;

[0128] Substitute the real-time temperature inside the detection box and the real-time temperature outside the detection box as a temperature combination into the temperature fitting function to obtain the surface target temperature;

[0129] Calibrate the insulation temperature to the surface target temperature.

[0130] The purpose of this adjustment is to eliminate the influence of the temperature of the external environment on the temperature inside the test box and ensure that the temperature inside the test box will not dissipate. Therefore, the temperature of the insulation layer is controlled to isolate the exchange of temperature inside and outside the test box, thereby making the temperature measurement result more accurate.

[0131] Reference Figure 6 As shown, according to the infrared scanning image, calculating the real-time reaction temperature in the detection box includes the following steps:

[0132] Obtain an infrared scanning image, identify a primary pixel value of each primary pixel point in the infrared scanning image, and obtain a primary temperature value corresponding to the primary pixel point according to the primary pixel value;

[0133] Get the primary number of primary pixels in the infrared scan image;

[0134] The infrared scanned image is evenly divided according to the primary number to obtain at least one primary equally divided block, each of which contains one primary pixel point;

[0135] The primary temperature value corresponding to the primary pixel point is used as the temperature of the primary equal-divided block;

[0136] Multiply the primary temperature value by the primary equal block to obtain the primary temperature composite value;

[0137] Superimpose the composite values ​​of primary temperatures corresponding to all primary pixels to obtain a comprehensive value of primary temperature;

[0138] Get the primary area of ​​the infrared scanning image, divide the primary temperature comprehensive value by the primary area, and get the real-time reaction temperature.

[0139] When performing temperature recognition, since the temperature distribution in the detection box is uneven, it is necessary to perform block recognition and summarize the temperature of each block to obtain the overall temperature in the detection box. Otherwise, the obtained temperature will have a large deviation, affecting the calculation of heat.

[0140] Reference Figure 7 As shown, according to the final reaction temperature and the initial reaction temperature, the mass of the effective substance in the sample is calculated, including the following steps:

[0141] According to the second heat formula, the heat release amount of the effective substance in the sample is calculated;

[0142] Divide the heat release of the effective substance by the corresponding reference heat generation heat and multiply by the unit mass to obtain the mass of the effective substance in the sample;

[0143] The second calorie formula is as follows:

[0144] P = cmT,

[0145] Among them, P is the heat released by the effective substance in the sample, c is the specific heat capacity of air, m is the mass of the air in the detection box, and T is the difference between the final reaction temperature and the initial reaction temperature.

[0146] Reference Figure 8 As shown, according to the mass of the effective substance in the sample, the preliminary content of the effective substance is obtained, which includes the following steps:

[0147] Obtain the total mass of the sampled sample;

[0148] Calculate the ratio of the mass of the effective substance in the sample to the total mass of the sample to obtain the preliminary content of the effective substance.

[0149] Reference Fig. 9As shown, calculating the real-time internal temperature in the detection box according to the infrared detection image includes the following steps:

[0150] Acquire an infrared detection image, identify the secondary chromaticity of each secondary pixel in the infrared detection image, and acquire a secondary temperature value corresponding to the secondary pixel according to the secondary chromaticity;

[0151] Get the secondary number of secondary pixels in the infrared detection image;

[0152] The infrared detection image is evenly divided according to the number of sub-levels to obtain at least one sub-level block, each of which contains one sub-pixel point;

[0153] The secondary temperature value corresponding to the secondary pixel point is used as the temperature of the secondary equal-divided block;

[0154] Multiply the secondary temperature value by the secondary equal block to obtain the secondary temperature composite value;

[0155] Superimpose the secondary temperature composite values ​​corresponding to all secondary pixel points to obtain the secondary temperature comprehensive value;

[0156] The secondary area of ​​the infrared detection image is obtained, and the comprehensive value of the secondary temperature is divided by the secondary area to obtain the real-time internal temperature.

[0157] Furthermore, the present solution also proposes a storage medium on which a computer-readable program is stored. When the computer-readable program is called, the above-mentioned method for detecting the effective ingredient content of the new electronic cigarette oil is executed.

[0158] It is understandable that the storage medium may be a magnetic medium, such as a floppy disk, a hard disk, or a magnetic tape; an optical medium, such as a DVD; or a semiconductor medium, such as a solid state drive (SSD).

[0159] In summary, the advantages of the present invention are: through the steps of obtaining the reference heat generation, adjusting the temperature of the insulation layer, and calculating the mass and mean content of the effective substance in the sampled sample, the content of the effective ingredient can be obtained by measuring the reaction heat. Since the temperature is obtained by image recognition, the temperature acquisition accuracy is high. At the same time, the temperature used for heat calculation is the temperature at the time of reaction, so the error caused by excessive reaction measurement can be avoided. Therefore, the error between the content of the effective ingredient and the actual content is small, which can meet more precise measurement needs.
