[0028] 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, and 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.
[0029] As described above, the resonant frequency required for microwave / RF heating devices is usually obtained through actual measurement or simulation of the coupled heated medium under no-load or loaded conditions. However, this method has the drawbacks of complex implementation and long implementation time. It cannot quickly identify the dielectric properties of the heated medium and the changes in the resonant frequency required at different heating stages during the heating process, thus resulting in a lack of continuity in the qualitative analysis of the entire heating system.
[0030] Based on this, embodiments of this application provide an aerosol analysis method. By performing RLC circuit equivalence on the aerosol generation system under different states, and qualitatively or quantitatively analyzing the changes in target parameters of the heated medium based on RLC current, since the analysis is based on circuit theory, the time-related cost is relatively low compared with actual measurement or simulation. Therefore, the aerosol analysis method provided by embodiments of this application can quickly analyze the changes in some specified parameters of the heated medium (i.e., the aerosol matrix) during the heating process.
[0031] The aerosol analysis method and related apparatus provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0032] like Figure 1 The diagram shown illustrates the structure of an aerosol generation system provided in an embodiment of this application. Figure 1 In this system, the aerosol generation system 100 mainly includes: a power supply 10, a radio frequency source 20, and a radio frequency radiator 30, wherein;
[0033] The power supply 10 is used to provide power to the radio frequency source 20;
[0034] When powered on, the radio frequency source 20 generates electromagnetic waves of a high-power signal in a certain radio frequency band with stable output; and transmits the electromagnetic waves to the radio frequency radiator 30.
[0035] The radio frequency radiator 30 is used to generate resonance in itself using electromagnetic waves, and to heat and atomize the aerosol matrix placed in the radio frequency radiator 30 to generate aerosol. In other words, the radio frequency radiator 30 serves as a container for holding the heated medium (i.e., the aerosol matrix) and a radiating element for generating the electric field that generates aerosol through radio frequency heating.
[0036] In practical applications, the aerosol generation system operates as follows: Upon startup, the power supply 10 is connected to the radio frequency source 20. The DC signal generated by the power supply 10 is converted into a high-power electromagnetic wave of a specific radio frequency band by the radio frequency source 20. This electromagnetic wave is then input to the radio frequency radiator 30, which couples with the heated medium, generating an electric field within the medium. The medium is then heated by this high-frequency electromagnetic field. Based on the dielectric heating principle, the heated medium is heated and generates aerosol within 0.5 to 5 seconds (s).
[0037] For example Figure 1 The aerosol generation system shown also suffers from the technical problems described above. Therefore, as follows... Figure 2 As shown, it illustrates a flowchart of an aerosol analysis method provided in an embodiment of this application.
[0038] exist Figure 2 In this method, the following steps may be included:
[0039] Step 201: The aerosol generation system is equivalent to a first RLC circuit under no-load conditions;
[0040] Step 202: When the aerosol generation system is under load, the aerosol matrix and the radio frequency radiator are equivalent to parallel capacitors; the capacitor in the first RLC circuit is replaced by the parallel capacitor to form the second RLC circuit of the aerosol generation system under load.
[0041] Step 203: Analyze the changes in target parameters during the heating process of the aerosol matrix based on the second RLC circuit.
[0042] It should be noted that this analytical method is to equate the different states of the aerosol generation system to different RLC circuits; then, based on the equivalent RLC circuits, the changes of the heated medium during the heating process are analyzed.
[0043] Specifically, step 201 may include: acquiring first network data of the aerosol generation system; the first network data includes key data for describing the equivalent single-port network performance of the aerosol system; obtaining the inductance value of the inductor, the capacitance value of the capacitor, the resistance value of the resistor, and the connection relationship between the inductor, capacitor, and resistor in the equivalent circuit model based on the first network data; and obtaining the first RLC circuit based on the connection relationship and the obtained inductance value of the inductor, the capacitance value of the capacitor, and the resistance value of the resistor.
[0044] It should be noted that the so-called first network data can be the data obtained by measuring the equivalent single-port network of the aerosol system under no-load conditions using a network analyzer. It mainly records the S-parameters of the single-port network, which are used to describe the performance of the RF equipment. This first network data can also be called S1P data or S1P file. S1P data or S1P file can be a network analysis data file format in an RF system, mainly used to describe the frequency response characteristics of RF and microwave devices, including the S-parameters (Scattering Parameters) of the single-port network. These parameters describe the scattering behavior of signals passing through the RF device. The S-parameters include S11, S12, S21, and S22, representing the reflection at the input port and the transmission between the two ports, respectively. S11 and S22 represent the reflection loss at the input and output ports, while S12 and S21 describe the transmission loss of the signal from one port to another.
[0045] In practical applications, obtaining the first network data of the aerosol generation system can be achieved through the following methods: Measuring the first network data of the aerosol generation system under no-load conditions using an RF network analyzer; that is, connecting the aerosol generation system to the port of the RF network analyzer, setting the required frequency range and power level on the RF network analyzer, and then performing the measurement; the network analyzer will provide S-parameters (scattering parameters), which describe the reflection and transmission characteristics of the signal between different ports. After the measurement is completed, the network analyzer can save the S-parameter data as an S1P file. The S1P file is a standard format used to store the S-parameter data of the aerosol generation system. Analyzing the extracted S-parameter data, such as S11, S21, S12, and S22, these parameters represent the reflection coefficient and transmission coefficient, respectively. Logarithmic transformation calculations can be used to visually view the corresponding dB values of return loss, gain, and reverse isolation.
[0046] After obtaining the first network data, the connection relationships between the inductors, capacitors, and resistors in the equivalent circuit model are selected. One possible implementation is that the first RLC circuit is a series RLC circuit, meaning that the capacitors, inductors, and resistors in the selected equivalent circuit model are connected in series. It should be noted that, depending on the actual operating mode of the electromagnetic device, the first RLC circuit may include, but is not limited to, parallel RLC circuits, multi-order RLC circuits, or other circuits capable of resonance. In other words, the structure of the first RLC circuit can be diverse, and the specific choice depends on the actual situation. This application embodiment only uses a series RLC circuit as an example for illustration.
[0047] In practical applications, S1P files typically contain data in complex form, where the real part represents the resistive component and the imaginary part represents the reactive component (inductance and capacitance). The impedance data in an S1P file can be expressed as Z = R + jX, where R is resistance, X is reactance, and j is the imaginary unit. The reactance X can be further decomposed into inductive reactance XL and capacitive reactance XC, i.e., X = XL - XC. Since the influence of inductance and capacitance is relatively small at low frequencies, impedance is mainly determined by resistance. Therefore, the resistance value can be estimated by examining the real part of the impedance at low frequencies. At high frequencies, the influence of inductance and capacitance becomes significant. By analyzing the imaginary part of the impedance, the values of inductive and capacitive reactance can be extracted. Inductive reactance XL is directly proportional to frequency, while capacitive reactance XC is inversely proportional to frequency. By measuring the impedance at different frequencies, the values of L and C can be solved. Therefore, obtaining the inductance value of the inductor, the capacitance value of the capacitor, and the resistance value of the resistor in the equivalent circuit model based on the first network data can include: obtaining the resistance value of the resistor based on the low-frequency data of the first network data; and obtaining the capacitance value of the capacitor and the inductance value of the inductor based on the high-frequency data of the first network data, thereby obtaining the first RLC circuit. Alternatively, circuit analysis software, such as ADS (Advanced Design System) or SPICE, can be used to fit the data in the S1P file (e.g., the first network data) to extract the RLC values.
[0048] Then, based on the selected connection relationship and the calculated inductance value of the inductor, the capacitance value of the capacitor, and the resistance value of the resistor, the first RLC circuit is finally determined.
[0049] For example, such as Figure 3 As shown, it illustrates the implementation of this application based on... Figure 1 The diagram shows a schematic representation of an equivalent first RLC circuit in an unloaded state for an aerosol generation system. Figure 3 In this circuit, the first RLC circuit is a series RLC circuit, and the values of R, L, and C can be obtained from the first network data.
[0050] In this embodiment, when the aerosol generation system is under load, i.e., the heated medium is placed in the radio frequency radiator, the coupling portion between the heated medium and the radio frequency radiator can be equivalent to a parallel capacitor. The parallel connection can be as follows: Figure 4 As shown. In Figure 4 In the middle, resistance and inductance and Figure 3The resistance and inductance are the same, only the capacitance is a parallel capacitance formed by the capacitance in the no-load state and the capacitance of the heated medium. That is, the parallel capacitance is equal to the sum of the capacitance in the first RLC circuit in the no-load state and the capacitance of the aerosol matrix. Furthermore, the capacitance of the aerosol matrix changes with the heating state. Based on this, the parallel capacitance also changes proportionally with the heating state during the heating process. It should be noted that C0 is the capacitance value of the equivalent RLC circuit of the aerosol system in the no-load state; C X This represents the capacitance value of the equivalent RLC circuit of the aerosol system when the aerosol matrix is heated to a certain state.
[0051] After obtaining the second RLC, the changes in the target parameters during the heating process of the aerosol matrix can be analyzed based on the second RLC circuit.
[0052] Specifically, if the target parameter includes the dielectric constant of the aerosol matrix; the analysis based on the second RLC circuit of the change of the target parameter during the heating of the aerosol matrix, such as... Figure 5 As shown, it may include:
[0053] Step 501: Obtain the second network data of the aerosol generation system; the second network data includes key data for describing the equivalent single-port network performance of the aerosol matrix in the aerosol system under a certain state during the heating process;
[0054] Step 502: Obtain the resonant frequency in the stated state based on the second network data;
[0055] Step 503: Based on the second RLC circuit, the resonant frequency in the state, and the capacitance in the first RLC circuit, predict the capacitance value corresponding to the aerosol matrix in the state;
[0056] Step 504: Predict the dielectric constant of the aerosol matrix in the state based on the capacitance value of the aerosol matrix in the state; the dielectric constant changes with the capacitance value of the aerosol matrix.
[0057] It should be noted that the "certain state" mentioned can include any state before heating or during heating after placing the aerosol matrix behind the RF radiator. In a certain state, the second network data of the second RLC circuit is obtained. Then, the resonant frequency in that state is calculated based on the second network data. Afterwards, the formula for calculating the resonant frequency is obtained from the second RLC circuit, and the obtained resonant frequency is input into the formula to obtain the parallel capacitance. Since the capacitance value in the unloaded state has already been calculated, the capacitance value of the heated medium in that state can be obtained. Then, according to the following formula: C = 2πεa[ln(2a / b)-1]. Where C is the equivalent coupling capacitance, ε is the equivalent dielectric constant, a is the outer diameter of the ring, and b is the inner diameter of the ring. Here, a and b are the outer and inner diameters of the RF radiator in the aerosol generation system when it is cylindrical. Given a certain aerosol generation system, a and b are known parameters. Therefore, it can be deduced that:
[0058] In practical applications, the dielectric constant of the heated medium can be calculated in the above manner under any state during the heating process. Therefore, the embodiments of this application can utilize an equivalent second RLC circuit to obtain the change in the dielectric constant of the heated medium during the heating process.
[0059] In some embodiments, if the target parameter includes a resonant frequency; the analysis based on the second RLC circuit of the change of the target parameter during the heating of the aerosol matrix, such as Figure 6 As shown, it may include:
[0060] Step 601: Determine the range of capacitance values of the aerosol matrix during the heating process;
[0061] Step 602: Based on the value range and the second RLC circuit, predict the resonant frequency during the heating process of the aerosol matrix.
[0062] It should be noted that if the range of capacitance values of the aerosol matrix during the heating process is known, that is, if the range of capacitance changes during the heating process is known, then according to Figure 4 The formula for calculating the resonant frequency of the second RLC circuit shown is as follows:
[0063]
[0064] Among them, f r C is the resonant frequency; C0 is the capacitance value in the first RLC circuit of the aerosol generation system under no-load conditions; C x denoted as x, where x represents the index of a given capacitance value during the heating process of the aerosol matrix.
[0065] Select multiple capacitance values C from this range of variation. x Then C x Substituting these values into the resonant frequency formula above, we can calculate each C. x The corresponding resonant frequency. Based on this method, the change of the required resonant frequency of the aerosol matrix (i.e., the heated medium) during the heating process can be obtained.
[0066] In some embodiments, if the target parameter includes a resonant frequency, the method may further include: determining a mapping relationship between the heating temperature of the aerosol matrix during heating, the morphology of the coupling portion between the aerosol matrix and the radio frequency radiator, the weight of the aerosol matrix and the capacitance of the aerosol matrix; and predicting the change of the resonant frequency of the aerosol matrix during heating based on the mapping relationship and the second RLC circuit.
[0067] It should be noted that during actual heating, the capacitance of the aerosol matrix can be a function of varying factors such as heating temperature, the morphology of the coupling portion between the aerosol matrix and the radio frequency radiator, and the weight of the aerosol matrix. In other words, the capacitance of the aerosol matrix has a mapping relationship with these factors. Under a given condition, the values of these factors are determined. Then, based on the mapping relationship, the capacitance of the aerosol matrix under that condition is determined. Then, using the resonant frequency formula mentioned above, the required resonant frequency for that condition can be obtained. Based on this method, the changes in the resonant frequency during the heating process can be obtained.
[0068] The aerosol analysis method provided in this application equates the aerosol generation system to an RLC circuit, and then predicts the dielectric constant or desired resonant frequency of the aerosol matrix based on the RLC circuit. Because it uses mathematical calculations, it saves time compared to actual measurements or simulations, meaning it can quickly obtain the desired results, making it more convenient. Furthermore, as... Figures 7 to 11 As shown, the predictions based on this equivalent circuit are compared with the measured or simulated results, and the differences are not significant. Therefore, this equivalent circuit method can be used for prediction. Figure 7 As shown Figure 1 The aerosol generation system shown is based on S1P data under different conditions (no load, before heating, and after heating) measured or simulated. Figure 8 As shown Figure 1 The aerosol generation system shown is based on different S1P data calculated using equivalent circuits; Figure 9 for Figure 1The diagram shows a comparison of S1P data based on measured or simulated data and S1P data calculated based on equivalent circuits under no-load conditions for the aerosol generation system. Figure 10 for Figure 1 The diagram shows a comparison of measured or simulated S1P data and S1P data calculated based on equivalent circuits before heating the aerosol generation system after the aerosol matrix is placed in it. Figure 11 for Figure 1 The diagram shows a comparison of S1P data based on measured or simulated data with S1P data calculated based on equivalent circuits after the aerosol generation system is heated following the introduction of the aerosol matrix. Figure 7 In the diagram, S(1,1) is the resonant frequency under no-load conditions; S(2,2) is the resonant frequency before heating; and S(3,3) is the resonant frequency after heating. Figure 8 In the diagram, S(4,4) is the resonant frequency under no-load conditions; S(6,6) is the resonant frequency before heating; and S(7,7) is the resonant frequency after heating. It should be noted that... Figures 7 to 11 In the diagram, m5, m6, and m7 are the inflection points of the resonant frequencies obtained from actual measurements or simulations of the aerosol system under no-load conditions, before heating, and after heating, respectively. Similarly, m10, m11, and m12 are the inflection points of the resonant frequencies obtained from actual measurements or simulations of the aerosol system under no-load conditions, before heating, and after heating, respectively, calculated using an equivalent RLC circuit. m1 and m2 are the inflection points of the resonant frequencies obtained from actual measurements or simulations, and calculated using an equivalent RLC circuit, respectively. m3 and m4 are the inflection points of the resonant frequencies obtained from actual measurements or simulations, and calculated using an equivalent RLC circuit, respectively, before heating, respectively. m8 and m9 are the inflection points of the resonant frequencies obtained from actual measurements or simulations, and calculated using an equivalent RLC circuit, respectively, after heating, respectively. The reason why the same inflection point has different names in different figures is likely because it is drawn in different figures for differentiation.
