[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0029] Please see Figure 4 On the one hand, embodiments of the present invention also provide a measuring system 500, such as... Figure 4 As shown, it includes a measuring device 400 and a weighing device 501. The measuring system 500 also includes an aerosol collecting device 502, a filtration detection device 503, and an air extraction device 504 connected in sequence. The weighing device 501 and the filtration detection device 503 are communicatively connected to the measuring device 400. The aerosol collecting device 502, the filtration detection device 503, and the air extraction device 504 are connected by a connecting pipe.

[0030] In this specific embodiment, the aerosol collection device 502 is used to collect the aerosol exhaled by the user. It can be an inflatable medical mask and is sealed and conducted to the filter detection device 503 through a connecting tube. The filter detection device 503 includes a Cambridge filter, a detection module, and a first transmission module. The Cambridge filter is used to obtain the exhaled nicotine of the aerosol matrix. The detection module is used to detect the exhaled nicotine to obtain the nicotine exhalation amount. The first transmission module is used to send the nicotine exhalation amount to the measuring device 400. The weighing device 501 is used to obtain the initial weight and the remaining weight of the aerosol matrix. It includes an electronic balance for weighing and a second transmission module. The electronic balance is accurate to milligrams. The second transmission module is used to send the initial weight and the remaining weight to the measuring device 400. The suction device 504 is an electronic suction machine used to effectively draw the aerosol exhaled by the user into its cylinder.

[0031] For ease of understanding, the working principle of the measurement system is as follows:

[0032] An inflatable medical mask is used for sealing and conduction. The aerosol exhaled by the consumer or reviewer is sealed through the inflatable medical mask and transported through a single connecting tube to a filtration and detection device. After being filtered by a Cambridge filter in the filtration and detection device, it is then transported to an electronic vacuum pump. Because there is only one channel in the entire transmission route, and the electronic vacuum pump creates a certain negative pressure during operation, it effectively draws the user's exhaled aerosol into its cylinder. During this process, the user rhythmically exhales aerosol through the inflatable medical mask according to the parameters set by the electronic vacuum pump, repeating the process a specified number of times. The nicotine in the exhaled aerosol is collected on the Cambridge filter in the filtration and detection device, and the weight of the exhaled nicotine is precisely measured by a detection module.

[0033] On the other hand, the present invention also provides a nicotine measuring device 400, such as... Figure 3 As shown, it includes

[0034] The first receiving unit 401 is used to receive the initial weight of the aerosol matrix and the remaining weight after the user inhales the aerosol matrix.

[0035] The first calculation unit 402 is used to calculate the nicotine consumption based on the initial weight and the remaining weight;

[0036] The second receiving unit 403 is used to receive the amount of nicotine expelled.

[0037] The second calculation unit 404 is used to calculate the nicotine absorption ratio based on the amount of nicotine excreted and the amount of nicotine consumed.

[0038] On the other hand, please refer to Figure 1 and Figure 2 The nicotine determination method of this invention, based on a nicotine-containing aerosol matrix, includes the following steps:

[0039] S100: Receive the initial weight of the aerosol matrix and the remaining weight after the user inhales the aerosol matrix;

[0040] In this embodiment of the invention, the initial weight of the aerosol matrix is ​​first obtained by a weighing device, and then the remaining weight of the aerosol matrix after the user has inhaled it is obtained. The initial weight and the remaining weight information are received from the weighing device. In this specific embodiment, the weighing device includes an electronic balance accurate to milligrams.

[0041] S200: Calculate the nicotine consumption based on the initial weight and the remaining weight;

[0042] In this embodiment of the invention, the total consumption of the aerosol matrix during user inhalation can be calculated and obtained based on the initial gravity and the remaining weight of the aerosol matrix; furthermore, based on the correspondence of nicotine in the aerosol matrix, the nicotine consumption can be calculated from the consumption of the aerosol matrix.

[0043] S300. If a nicotine discharge is received, the nicotine absorption ratio is calculated based on the nicotine discharge and the nicotine consumption.

[0044] In this embodiment of the invention, the portion of nicotine exhaled by the user during inhalation of the aerosol matrix is ​​collected and further filtered and detected by a nicotine detection device. The amount of nicotine exhaled is then precisely measured. After receiving the amount of nicotine exhaled, the absorption amount and proportion of nicotine absorbed by the user during inhalation are calculated based on the amount exhaled and the amount consumed. In this specific embodiment, the filtration and detection device includes a Cambridge filter used to collect the exhaled nicotine and further precisely measure its weight. The nicotine absorption amount is obtained by the difference between the nicotine exhaled and the nicotine consumed; the ratio of the nicotine absorption amount to the nicotine consumption amount is calculated to determine the proportion of nicotine absorbed by the human body.

[0045] In embodiments of the present invention, such as Figure 2 The schematic diagram of the nicotine determination method shown includes the following steps in calculating nicotine consumption based on the initial weight and the remaining weight:

[0046] S210. Calculate the difference between the initial weight and the remaining weight to obtain the consumption of the aerosol matrix;

[0047] S220. Calculate the nicotine consumption based on the consumption of the aerosol matrix using a preset formula.

[0048] In a specific embodiment, after receiving the initial weight and remaining weight information sent by the weighing device and calculating the difference between the initial weight and the remaining weight to obtain the aerosol matrix consumption amount Δm, and the nicotine mass ratio α contained in the aerosol matrix is ​​preset, its proportion can be 1%, 2%, 3%, etc.; then the nicotine consumption amount m2 can be calculated by multiplying the aerosol matrix consumption amount by the nicotine mass ratio, that is, the preset formula m2=Δm*α.
