[0002] This application relates to the technical field of aerosol generation, and more specifically, to a control method, a control module, and an aerosol generator.

Background Art

[0003] An aerosol generator, for example, a non-combustion and heating type (Heat Not Burning, HNB) low-temperature heating appliance, is mainly a new type of electronic atomizer that heats and atomizes a solid "aerosol generation substrate". Because it is healthy and has high cost performance, it is welcomed by many users. As the requirements for the intelligence of aerosol generators are becoming increasingly high, it is desired that aerosol generators have a function of automatically starting heating. However, current aerosol generators cannot identify whether the "aerosol generation substrate" is loaded, so they cannot realize automatically starting heating.

Embodiments for Carrying Out the Invention

[0012] The embodiments of the present application will be described in detail below, but these embodiments are illustrated in the drawings, and the same or similar reference numerals in the drawings consistently indicate the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are for illustrative purposes only, and should not be understood as limiting the present application.

[0013] In the description of embodiments of this application, the terms “first” and “second” are used solely for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features described. Thus, features limited by “first” and “second” may explicitly or implicitly include one or more of the aforementioned features. In the description of embodiments of this application, unless otherwise clearly and specifically limited, “multiple” means two or more.

[0014] As shown in Figures 1, 2, and 4, the control method according to the embodiment of the present application is applied to an aerosol generator 100 (shown in Figure 23), and the control method includes the following steps 01 to 04.

[0015] In step 01, a high-frequency analog signal is output by a high-frequency oscillation circuit 133 in the high-frequency signal generation unit 13. The high-frequency signal generation unit 13 includes a capacitor to be measured 1311, which is provided on the substrate 11 and connected to the high-frequency oscillation circuit 133. The high-frequency analog signal is configured to represent the capacitance of the capacitor to be measured 1311.

[0016] Step 02 converts the high-frequency analog signal into a measurable signal.

[0017] Step 03 involves measuring the signal parameters of the measurable signals.

[0018] In step 04, it is determined whether or not the aerosol generating substrate 20 is loaded onto the base 11 based on the signal parameters and predetermined reference parameters.

[0019] The control module 10 applied to the aerosol generator 100 according to the embodiment of the present application includes a base 11, a high-frequency signal generation unit 13, a signal conversion unit 15, and a main control unit 17. The high-frequency signal generation unit 13 includes a capacitor assembly 131 to be measured and a high-frequency oscillation circuit 133. The capacitor assembly 131 includes a capacitor 1311 to be measured, which is mounted on the base 11 and connected to the high-frequency oscillation circuit 133. The high-frequency oscillation circuit 133 outputs a high-frequency analog signal, which is configured to represent the capacitance of the capacitor 1311 to be measured. The signal conversion unit 15 is connected to the high-frequency oscillation circuit 133 and converts the high-frequency analog signal into a measurable signal. The main control unit 17 is connected to the signal conversion unit 15 and measures the signal parameters of the measurable signal, and determines whether or not an aerosol generation substrate 20 is loaded into the base 11 based on the signal parameters and predetermined reference parameters. In this embodiment, the aerosol generating substrate 20 may be tobacco, specifically, the tobacco may include at least two sections: a substrate section having tobacco material and a filter section connected to one end of the substrate section. The substrate section may include solid materials such as shredded tobacco, sheet tobacco, or tobacco granules, and organic substances such as corresponding fragrance materials may be added to release aroma when heated. At least one cooling section may be included between the substrate section and the filter section, whose function is to extend the aerosol transport pathway and lower its temperature. The aerosol generating substrate 20 is loaded into the base body 11 by insertion.

[0020] As shown in Figures 4 and 6, the substrate 11 is a component for forming a capacitor, and the substrate 11 may be a columnar structure with a housing cavity, and the columnar structure may be a cylindrical structure, a prismatic structure or a triangular prismatic structure, etc., and is not limited thereto, and the housing cavity houses the aerosol generating substrate 20. When the aerosol generating substrate 20 is loaded into the substrate 11, the aerosol generating substrate 20 is heated by the heat generated by the heating element, the corresponding components are volatilized and an aerosol is generated, which can then be inhaled by the user. In one embodiment, the substrate 11 is made of a non-conductive material such as glass, high-temperature resistant resin or engineering plastic. In another embodiment, the substrate 11 is made of a conductive material such as a conductive metal, specifically copper or aluminum. When the substrate 11 is made of a conductive material, the substrate 11 may generate heat as a heating element.

[0021] The frequency of a "high-frequency analog signal" is usually high, generally greater than 20 MHz, making it impossible to accurately measure the data with current measuring equipment. While accurate measurement is possible with precision measuring equipment, it is costly and lacks versatility. Therefore, it is advisable to first convert the "high-frequency analog signal" into a "measurable signal," as the frequency of the "measurable signal" is much lower than that of the "high-frequency analog signal," allowing for more accurate measurement with current measuring equipment. "Signal parameters" include data such as frequency and amplitude, while "reference parameters" are data such as frequency and amplitude that can be acquired before the aerosol generator 100 is shipped and directly recalled by the aerosol generator 100 after shipment. In this application, both "signal parameters" and "reference parameters" are explained as being frequencies. The "reference parameters" are values ​​set when the aerosol generator 100 is calibrated before shipment. These values ​​may be set according to the specific calibration conditions. Different aerosol generators 100 of different model numbers may use different "reference parameters," and aerosol generators 100 of the same model number may use the same "reference parameters" or different "reference parameters."

[0022] The control method and control module 10 of the present invention output a high-frequency analog signal using a high-frequency signal generation unit 13, convert the high-frequency analog signal into a measurable signal, measure the signal parameters of the measurable signal, and finally determine whether or not the aerosol generating substrate 20 is loaded into the base body 11 based on the signal parameters and predetermined reference parameters. If it is intelligently determined that the aerosol generating substrate 20 is loaded into the base body 11, the objective of intelligently starting the aerosol generator 100 to heat the aerosol generating substrate 20 can be achieved, and if it is intelligently determined that the aerosol generating substrate 20 is not loaded into the base body 11, the objective of intelligently stopping the aerosol generator 100 can be achieved.

[0023] As shown in Figures 2 to 4, in some embodiments, step 04, which identifies whether or not the aerosol generating substrate 20 is loaded into the substrate 11 based on signal parameters and predetermined reference parameters, includes the following steps 041 to 043.

[0024] In step 041, if the difference between the signal parameter and the reference parameter is within a first predetermined range, it is determined that the aerosol generating substrate 20 is not loaded into the base 11.

[0025] In step 043, if the difference between the signal parameter and the reference parameter is within a second predetermined range, it is determined that the aerosol generating substrate 20 is loaded into the base 11.

[0026] The main control unit 17 further determines that the aerosol generating substrate 20 is not loaded into the base 11 if the difference between the signal parameter and the reference parameter is within a first predetermined range, and determines that the aerosol generating substrate 20 is loaded into the base 11 if the difference between the signal parameter and the reference parameter is within a second predetermined range.

[0027] The "first predetermined range" and the "second predetermined range" are both calibration data that can be acquired by the aerosol generator 100 before shipment and that can be directly recalled by the aerosol generator 100 after shipment. The "first predetermined range" is the parameter range (frequency range) for which it is determined that the aerosol generating substrate 20 is not loaded into the base 11, and the "second predetermined range" is the parameter range (frequency range) for which it is determined that the aerosol generating substrate 20 is loaded into the base 11. Unlike the "first predetermined range," the lower limit of the "second predetermined range" is usually greater than the upper limit of the "first predetermined range." For example, if the "first predetermined range" is 550Hz to 570Hz and the difference between the signal parameter and the reference parameter is between 550Hz to 570Hz, for example, 560Hz, it indicates that the aerosol generating substrate 20 is not loaded into the base 11. If the "second predetermined range" is 2980Hz to 3000Hz and the difference between the signal parameter and the reference parameter is between 2980Hz to 3000Hz, for example, 2980Hz, it indicates that the aerosol generating substrate 20 is loaded into the base 11.

[0028] In some embodiments, as shown in Figure 4, the capacitor to be measured 1311 includes two conductive plates, the two plates being insulated from each other with a gap in the height direction of the base 11. In one example, both plates are annular plates surrounding the peripheral wall of the base 11, and as shown in Figure 4(a), both plate A and plate B are annular plates surrounding the peripheral wall of the base 11, and plate A and plate B constitute one capacitor to be measured 1311. In another example, one of the two plates is provided on the end face of the base 11, and the other is an annular plate surrounding the peripheral wall of the base 11, and as shown in Figure 4(b), plate A is an annular plate surrounding the peripheral wall of the base 11, and plate B is provided on the end face of the base 11, and plate A and plate B constitute one capacitor to be measured 1311. Furthermore, the annular plates may be closed annular plates, that is, both plates A and B have circular cross-sections; the annular plates may also be open annular plates, that is, both plates A and B have C-shaped cross-sections; and the two plates may be a combination of an open annular plate and a closed annular plate, for example, one of plates A and B may be a closed annular plate with a circular cross-section, and the other may be an open annular plate with a C-shaped cross-section.

[0029] As shown in Figure 7, the edges on both sides of the annular electrode plate in the height direction (edges in the circumferential direction) of the base 11 include one or more of the following shapes: arc-shaped, rectangular, arch-shaped, triangular, and spiral. The edges on both sides of the annular electrode plate in the height direction of the base 11 include one or more of the following shapes: linear, nonlinear, planar, or non-planar.

[0030] If the substrate 11 is made of a non-conductive material, the electrodes A and B may be attached to the substrate 11 by bonding. In this case, the electrodes A and B are flexible, and of course, the electrodes A and B may also be attached to the substrate 11 by coating or plating. If the substrate 11 is made of a conductive material, the electrodes A and B are partial structures separated from the substrate 11, and they can insulate each other to form a single capacitor 1311 to be measured.

[0031] In some other embodiments, as shown in Figure 4, the capacitor to be measured 1311 includes two conductive plates, the two plates distributed circumferentially around the substrate 11 and insulated from each other with a gap between them. As shown in Figure 4(c), plates A and B are distributed circumferentially around the substrate 11 and insulated from each other with a gap between them, forming a covered type capacitor to be measured 1311.

[0032] In this case, as shown in Figure 8, the edges on both sides of the base 11 in the circumferential direction of the plates of the coated capacitor 1311 (the edges in the circumferential direction) include one or more of the following shapes: arc, rectangle, bow, triangle, and spiral. The edges on both sides of the base 11 in the circumferential direction of the plates of the coated capacitor 1311 (the edges in the circumferential direction) include one or more of the following shapes: linear, nonlinear, planar, or non-planar.

[0033] In some embodiments, as shown in Figure 4, the number of capacitors 1311 to be measured may be one. In some other embodiments, as shown in Figure 6, the number of capacitors 1311 to be measured may be at least two, for example, two, three, or more.

[0034] Furthermore, as shown in Figure 6, when there are multiple (at least two) capacitors 1311 to be measured, in some embodiments, the plates of each capacitor 1311 are all circumferential plates, the two plates of each capacitor 1311 are independent of each other, and the multiple plates form pairs to form each capacitor 1311. In one example, each pair of plates is formed sequentially in pairs along the height direction of the base 11, and as shown in Figure 6(a), specifically, plate A and plate B form a pair to form one capacitor 1311, and plate C and plate D form a pair to form another capacitor 1311. In another example, each pair of plates is formed alternately in pairs with spacing along the height direction of the base 11, as shown in Figure 6(b). Specifically, plates A, B, C, and D are provided sequentially along the height direction of the base 11, with plates A and C forming one capacitor 1311, and plates B and D forming another capacitor 1311.

[0035] Furthermore, as shown in Figure 6, when there are multiple (at least two) capacitors 1311 to be measured, in some other embodiments, the multiple capacitors 1311 share one plate, and the other plates of each capacitor 1311 are provided on the base 11 at intervals from each other. In one example, as shown in Figure 6(c), the shared plate E is provided on the end face of the base 11, and plates A, B, C and D are provided on the base 11 at intervals from each other, with plates E and A forming a pair to form one capacitor 1311, plates E and B forming a pair to form one capacitor 1311, plates E and C forming a pair to form one capacitor 1311, and plates E and D forming a pair to form one capacitor 1311. In another example, as shown in Figure 6(d), plates A, B, C, and D are provided on the base 11 with space between them, plate D is a common plate, plate D and plate A form a pair to form one capacitor 1311, plate D and plate B form a pair to form one capacitor 1311, and plate D and plate C form a pair to form one capacitor 1311.

[0036] As shown in Figure 6, if there are multiple (at least two) capacitors to be measured, in yet another embodiment, all of the multiple capacitors to be measured 1311 are coated type capacitors 1311. As shown in Figure 6(e), plates A and B form one coated type capacitor 1311 when paired, plates C and D form one coated type capacitor 1311 when paired, and two coated type capacitors 1311 are provided spaced apart along the height direction of the base 11.

[0037] As shown in Figures 2 and 5, in some embodiments, there are at least two capacitors 1311 to be measured, and at least two capacitors 1311 to be measured are sequentially provided on the substrate 11 along the height direction of the substrate 11, and both are connected to the high-frequency oscillation circuit 133. Step 01, in which a high-frequency analog signal is output by the high-frequency oscillation circuit 133 in the high-frequency signal generation unit 13, Step 011 includes outputting a plurality of high-frequency analog signals using a high-frequency oscillation circuit 133, which are used to represent the capacitance of at least two capacitors 1311 to be measured, respectively. Step 02, which converts a high-frequency analog signal into a measurable signal, The step 021 includes converting multiple high-frequency analog signals into multiple measurable signals, Step 03, which measures the signal parameters of a measurable signal, The step 031 includes measuring the signal parameters of each measurable signal, Step 04, which determines whether or not the aerosol generating substrate 20 is loaded into the substrate 11 based on signal parameters and predetermined reference parameters, Step 045 determines that the aerosol generating substrate 20 is not loaded into the base 11 if the difference between all signal parameters and reference parameters is within a first predetermined range. The process includes step 047, which determines that the aerosol generating substrate 20 is loaded into the substrate 11 if the difference between any signal parameter and a reference parameter is within a second predetermined range. Correspondingly, the high-frequency oscillation circuit 133 is further configured to output multiple high-frequency analog signals used to represent the capacitance of multiple capacitors 1311 to be measured, respectively. The signal conversion unit 15 is further configured to convert the multiple high-frequency analog signals into multiple measurable signals. The main control unit 17 is further configured to measure the signal parameters of each measurable signal and determine that the aerosol generating substrate 20 is loaded into the substrate 11 if the difference between any signal parameter and a reference parameter is within a second predetermined range, and to determine that the aerosol generating substrate 20 is not loaded into the substrate 11 if the difference between all signal parameters and reference parameters is within a first predetermined range.

[0038] Whether there is one or at least two capacitors 1311 to be measured, the equivalent circuit between the two plates and the aerosol generating substrate 20 for each capacitor 1311 is as shown in Figure 9. If the aerosol generating substrate 20 is considered equivalent to one plate C of the capacitor, then plate A and the aerosol generating substrate 20 form capacitor (1), and plate B and the aerosol generating substrate 20 form capacitor (2). A schematic diagram of the formed equivalent capacitors is shown in the right-hand figure of Figure 9. The theoretical formula for capacitance is C = ε(S / d), where C is the capacitance value, ε is the dielectric constant between the plates, S is the plate area, and d is the distance between the plates. Since the conductivity of the aerosol generating substrate 20 is much lower than that of plates A and B, when the aerosol generating substrate 20 is loaded between plates A and B, it corresponds to a change in the dielectric constant ε of the material between plates A and B, and as a result, the capacitance between plates A and B changes. Whether or not the aerosol generating substrate 20 is loaded between plates A and B can be determined by whether or not the capacitance between plates A and B changes. The aerosol generating substrate 20 may be tobacco, solid drugs, or other solid substances. Alternatively, the aerosol generating substrate 20 may be a liquid substance contained in a solid container.

[0039] In some embodiments, as shown in Figures 2 and 9, the capacitor assembly 131 to be measured includes only the capacitor Cx to be measured, and the capacitor Cx includes two plates provided on the substrate 11, for example, plate A and plate B, in which case the high-frequency oscillator circuit 133 is directly connected to the two plates (plate A and plate B) of the capacitor Cx to be measured. In this case, the high-frequency analog signal output from the high-frequency oscillator circuit 133 directly represents the capacitance of the capacitor Cx to be measured, and is very direct and accurate.

[0040] In some other embodiments, as shown in Figures 2, 10 to 13, the capacitor assembly 131 to be measured includes the capacitor to be measured Cx and at least one composite capacitor, the capacitor to be measured Cx including two plates provided on a substrate 11, for example, plate A and plate B. The composite capacitor may be a finished capacitor manufactured by a capacitor manufacturer, or it may be a capacitor made of structural members. The capacitor to be measured Cx is connected in series, in parallel, or in series-parallel with at least one composite capacitor, the composite capacitor is connected to the high-frequency oscillation circuit 133, and thereafter at least one plate of the capacitor to be measured Cx is connected to the high-frequency oscillation circuit 133 via the composite capacitor. Since the capacitor Cx to be measured is provided on the base 11, there are certain wiring difficulties in directly connecting the high-frequency oscillation circuit 133 and the two plates of the capacitor Cx to be measured. In this embodiment, by providing a composite capacitor, the capacitor Cx to be measured can be drawn out from the base 11 and then connected to the high-frequency oscillation circuit 133, thereby realizing an indirect connection between the capacitor Cx to be measured and the high-frequency oscillation circuit 133 and reducing the difficulty of wiring.

[0041] Specifically, in one example, as shown in Figure 10, the capacitor assembly 131 to be measured further includes a composite capacitor C1 and a composite capacitor C2, and the composite capacitor C1, the capacitor to be measured Cx, and the composite capacitor C2 are connected in series sequentially. As shown in Figure 16, plate A of the capacitor to be measured Cx is connected to the first capacitor terminal Cap1 of the high-frequency oscillation circuit 133 via the composite capacitor C1, and plate B of the capacitor to be measured Cx is connected to the second capacitor terminal Cap2 of the high-frequency oscillation circuit 133 via the composite capacitor C2.

[0042] In another example, as shown in Figure 11, the capacitor assembly 131 to be measured includes a composite capacitor C1 and a composite capacitor C2, and the composite capacitor C1, the capacitor to be measured Cx, and the composite capacitor C2 are connected in parallel. As shown in Figure 16, plates A and B of the capacitor to be measured Cx are connected in parallel to the composite capacitors C1 and C2, and the two plates of the composite capacitor furthest from the base 11 are connected to the first capacitor terminal Cap1 and the second capacitor terminal Cap2 of the high-frequency oscillation circuit 133, respectively.

[0043] In yet another example, as shown in Figure 12, the capacitor assembly 131 to be measured further includes composite capacitors C1, C2, C3, and C4, and the capacitor Cx to be measured is connected in parallel with composite capacitors C1 and C2, and then in series with composite capacitors C3 and C4. As shown in Figure 16, plate A of the capacitor Cx to be measured is connected to the first capacitor terminal Cap1 of the high-frequency oscillation circuit 133 via composite capacitor C3, and plate B of the capacitor Cx to be measured is connected to the second capacitor terminal Cap2 of the high-frequency oscillation circuit 133 via composite capacitor C4.

[0044] In another example, as shown in Figure 13, the capacitor assembly 131 to be measured further includes composite capacitors C1, C2, C3, and C4, where composite capacitors C1, C2, and C3 are connected in parallel and then connected in series with the capacitor to be measured Cx and composite capacitor C4. As shown in Figure 16, plate B of the capacitor to be measured Cx is connected to the first capacitor terminal Cap1 of the high-frequency oscillation circuit 133 via composite capacitor C4, and plate A of the capacitor to be measured Cx is directly connected to the second capacitor terminal Cap2 of the high-frequency oscillation circuit 133.

[0045] The number of composite capacitors in the capacitor assembly 131 to be measured, and their connection relationships with the capacitor Cx to be measured, are not limited to the methods shown in Figures 9 to 13, and other configurations may also be used; these are not listed here.

[0046] Furthermore, if there are two or more capacitors Cx to be measured, the number of capacitor terminals of the high-frequency oscillation circuit 133 is the same as the total number of plates of the capacitors Cx to be measured. In this case, in one example, both plates of each capacitor Cx to be measured are directly connected to the capacitor terminal Cap of the high-frequency oscillation circuit 133. In another example, both plates of some capacitors Cx to be measured are directly connected to the capacitor terminal Cap of the high-frequency oscillation circuit 133, and at least one plate of some other capacitors Cx to be measured is connected to the capacitor terminal Cap of the high-frequency oscillation circuit 133 via a composite capacitor.

[0047] The capacitor assembly 131 under measurement and the high-frequency oscillation circuit 133 constitute a high-frequency signal generation unit 13, and a change in the capacitance value of the capacitor assembly 131 under measurement can cause a change in the oscillation frequency of the high-frequency oscillation circuit 133. As shown in Figure 14, the high-frequency oscillation circuit 133 may be an LC oscillation circuit. As shown in Figure 15, the high-frequency oscillation circuit 133 may be a crystal oscillation circuit. The high-frequency oscillation circuit 133 may be an active crystal oscillator or an integrated chip, and is not limited to these. The circuit structure of the high-frequency oscillation circuit 133 will be described below.

[0048] Specifically, as shown in Figure 16, the high-frequency oscillation circuit 133 includes an integrated oscillation unit 1333 and an LC oscillation unit 1331. The output pins of the integrated oscillation unit 1333 are connected to the signal conversion unit 15. The first capacitor terminal Cap1 of the LC oscillation unit 1331 is connected to one plate of the capacitor to be measured 1311. The second capacitor terminal Cap2 of the LC oscillation unit 1331 is connected to the other plate of the capacitor to be measured 1311, and the second capacitor terminal Cap2 is grounded.

[0049] More specifically, the high-frequency oscillator circuit 133 further includes capacitors C2, C13, C14, C15, C16, C19, C29, resistors R11, R12, R6, and R17. The LC oscillator unit 1331 includes capacitors C27, C18, C20, C24, resistor R13, and inductor L2. The first pin of the integrated oscillator unit 1333 is grounded via capacitor C15, and resistor R6 has one end connected between the first pin and capacitor C15 and the other end connected to the power supply. The power supply is grounded via capacitor C2. The second pin of the integrated oscillator unit 1333 is connected to the first capacitor terminal Cap1 after passing sequentially through capacitor C18 and resistor R13. Capacitor C27 has one end connected between the first capacitor terminal Cap1 and resistor R13 and the other end connected to ground. Inductor L2 is connected at one end between resistor R13 and capacitor C18, and the other end is grounded. Capacitors C20 and C24 are connected in series between the second pin and capacitor C18, and then grounded. The third pin of the integrated oscillator unit 1333 is connected between capacitors C20 and C24. The fourth pin of the integrated oscillator unit 1333 is connected to the third measurement point via resistor R17. Capacitor C16 is connected at one end between the fourth pin and resistor R17, and the other end is grounded. The fifth pin of the integrated oscillator unit 1333 is grounded sequentially via resistor R12 and capacitor C29, the power supply is connected between resistor R12 and capacitor C29, and the second measurement point is provided between the fifth pin and resistor R12. The sixth pin of the integrated oscillator unit 1333 is grounded. The seventh pin of the integrated oscillator unit 1333 is grounded via capacitor C19, and the power supply is connected between the seventh pin and capacitor C19. The eighth pin of the integrated oscillator unit 1333 is grounded via sequential resistor R11 and capacitor C13, and the power supply is connected between resistor R11 and capacitor C13, with resistor R11 connected in parallel across capacitor C14. A high-frequency analog signal may be output from the eighth pin to the signal conversion unit 15.

[0050] Note that the high-frequency oscillator circuit 133 shown in Figure 16 is designed with only two capacitor terminals. If there are multiple capacitors 1311 to be measured, the number of capacitor terminals increases accordingly, and the number of capacitor terminals matches the number of plates of all capacitors 1311 to be measured. The eighth pin of the integrated oscillator unit 1333 is an output terminal that outputs a high-frequency analog signal corresponding to one capacitor 1311 to be measured. If there are multiple capacitors 1311 to be measured, the integrated oscillator unit 1333 may be designed to have multiple output terminals, each output terminal outputting a high-frequency analog signal corresponding to one capacitor 1311 to be measured.

[0051] After the high-frequency oscillation circuit 133 outputs a high-frequency analog signal, the signal conversion unit 15 can convert the high-frequency analog signal into a measurable signal. As shown in Figure 17(a), in some embodiments, the measurable signal may be a high-frequency digital signal, and the signal conversion unit 15 performs analog-to-digital conversion processing on the high-frequency analog signal to obtain a high-frequency digital signal, in which case the main control unit 17 measures the signal parameters of the "high-frequency digital signal". As shown in Figure 17(b), in some other embodiments, the measurable signal may be a low-frequency analog signal, and the signal conversion unit 15 performs frequency conversion processing on the high-frequency analog signal to obtain a low-frequency analog signal having a lower frequency than the high-frequency analog signal, in which case the main control unit 17 measures the signal parameters of the "low-frequency analog signal". As shown in Figure 17(c), in yet another embodiment, the measurable signal may be a low-frequency digital signal, and the signal conversion unit 15 performs frequency conversion processing and analog-to-digital conversion processing on the high-frequency analog signal to obtain a low-frequency digital signal having a lower frequency than the high-frequency analog signal, in which case the main control unit 17 measures the signal parameters of the "low-frequency digital signal". Hereinafter, we will explain as an example a case in which the measurable signal is a low-frequency digital signal and the signal conversion unit 15 performs frequency conversion processing and analog-to-digital conversion processing on the high-frequency analog signal to obtain a low-frequency digital signal having a lower frequency than the high-frequency analog signal.

[0052] Specifically, as shown in Figure 18, the signal conversion unit 15 includes a comparator 151 and a digital frequency divider 153. The comparator 151 receives a high-frequency analog signal generated from the high-frequency oscillation circuit 133 and converts the high-frequency analog signal into a high-frequency digital signal. The digital frequency divider 153 performs a 10-division process on the high-frequency digital signal to obtain a low-frequency digital signal. In one example, the Frequency Input of the signal conversion unit 15 is connected to the 8th pin of the integrated oscillation unit 1333 to receive the high-frequency analog signal. Fre-OUT1 of the signal conversion unit 15 is connected to the main control unit 17 and transmits the low-frequency digital signal to the main control unit 17. The main control unit 17 measures the signal parameters of the "low-frequency digital signal" and determines whether or not the aerosol generating substrate 20 is loaded into the substrate 11 based on the signal parameters and predetermined reference parameters.

[0053] If the method in step 04 (including steps 043 and 047) determines that the aerosol generating substrate 20 is loaded onto the substrate 11, the control method may further include step 05 of controlling the substrate 11 to heat, as shown in Figures 19 and 20.

[0054] In this case, if the main control unit 17 determines that the aerosol generating substrate 20 is loaded onto the substrate 11, it controls the substrate 11 to heat up. In some embodiments, the substrate 11 is made of a conductive material, and the substrate 11 may also be a heating element, in which case the main control unit 17 can directly control the substrate 11 to heat up. In some other embodiments, the substrate 11 is made of a non-conductive material, and a heating element is provided near the substrate 11, in which case the main control unit 17 can heat the substrate 11 by controlling the heating element to heat up.

[0055] The control module 10 according to the embodiment of the present application controls the heating of the substrate 11 only when it is determined that the aerosol generating substrate 20 is loaded into the substrate 11. On the one hand, it can achieve the objective of intelligently determining when the aerosol generating substrate 20 is loaded and intelligently starting the heating of the aerosol generating substrate 20. On the other hand, it can achieve the objective of intelligently determining when the aerosol generating substrate 20 is withdrawn and intelligently stopping the heating of the aerosol generating substrate 20. Furthermore, it avoids erroneous heating when the aerosol generating substrate 20 is not present in the aerosol generator 100 and prevents dry heating when the aerosol generating substrate 20 is absent, thus providing a certain level of intelligent safety.

[0056] Furthermore, as shown in Figures 19 and 20, when the substrate 11 is heated, the control method may further include step 06 of determining whether or not the aerosol generating substrate 20 is inhaled and the number of inhalations based on changes in signal parameters.

[0057] In this case, when the substrate 11 is heated, the main control unit 17 determines whether or not the aerosol generating substrate 20 is inhaled and the number of inhalations based on the change in signal parameters.

[0058] The main control unit 17 determines that the aerosol generating substrate 20 is loaded onto the base 11 and, based on the measured initial signal parameters, for example, if the initial frequency is 65 MHz, when the base 11 is heated, aerosol fills the space between the capacitor plates, increasing the capacitance value and decreasing the frequency. The more aerosol there is, the lower the frequency, and different amounts of aerosol generate result in different resonant frequencies, with the resonant frequency being between 59 MHz and 62 MHz. After dividing the frequency by 10, the frequency is between 57 kHz and 61 kHz. Based on the collected frequency change trend, the main control unit 17 can detect the suction action and the number of suctions. For example, during heating, aerosol fills the space between the capacitor plates, and the frequency after division is measured to be approximately 59 kHz. After suction, the aerosol flows out, and the frequency after division increases to approximately 61 kHz. The frequency change can reflect the suction action, and by statistically counting the number of times the suction action occurs, the number of suctions for the aerosol generating substrate 20 can be obtained.

[0059] Normally, the number of times the aerosol generator 100 is inhaled is constant, approximately 15 times. When the aerosol generating substrate 20 is inhaled 15 times, the aerosol generating substrate 20 is completely consumed, and if the heating element or base 11 continues to be heated, the aerosol generating substrate 20 will dry-fire, generating harmful substances. Therefore, if the number of times the aerosol generating substrate 20 is inhaled can be intelligently statistically recorded, the main control unit 17 can control the heating of the heating element or base 11 to stop after the statistically recorded number of inhalations reaches a predetermined number, for example, after 15 times, thereby preventing dry-fire when the aerosol generating substrate 20 is completely consumed and providing a certain level of intelligent safety.

[0060] As shown in Figure 21, step 06, which determines whether or not the aerosol-generating substrate 20 is absorbed based on a change in signal parameters, may further include step 061, which determines that the aerosol-generating substrate 20 is absorbed when the signal parameters increase from an initial value when the substrate 11 is heated to a predetermined value.

[0061] In this case, the main control unit 17 determines that the aerosol generating substrate 20 is being drawn in when the signal parameter increases from an initial value (when the substrate 11 is heated) to a predetermined value.

[0062] Furthermore, as shown in Figure 21, step 06, which determines the number of inhalations of the aerosol generating substrate 20 based on the change in signal parameters, Step 063 records the number of times the signal parameter increases from an initial value to a predetermined value when the substrate 11 is heated, and then returns from the predetermined value to the initial value. The process may further include step 065, where the number of times is the number of inhalations relative to the aerosol generating substrate 20.

[0063] In this case, the main control unit 17 is further configured to record the number of times the signal parameter increases from an initial value to a predetermined value when the substrate 11 is heated, and then returns from the predetermined value to the initial value, and to use this number as the number of times the aerosol generating substrate 20 is inhaled.

[0064] As shown in Figure 22, in some embodiments, there are at least two capacitors 1311 to be measured, and at least two capacitors 1311 to be measured are sequentially provided on the substrate 11 along the height direction of the substrate 11, and all are connected to the high-frequency oscillation circuit 133, the control method may further include step 07 of determining the loading depth of the aerosol generating substrate 20 based on the position of the capacitor 1311 on the substrate 11 corresponding to any of the signal parameters, if the difference between any of the signal parameters and a reference parameter is within a second predetermined range.

[0065] In this case, the main control unit 17 is further configured to determine the loading depth of the aerosol generating substrate 20 based on the position of the condenser 1311 on the substrate 11 corresponding to any of the signal parameters, if the difference between any of the signal parameters and the reference parameter is within a second predetermined range.

[0066] For example, as shown in Figure 6(a), if the difference between the signal parameter and the reference parameter corresponding to the upper capacitor 1311 (formed by a pair of plates A and B) is within a second predetermined range, and the difference between the signal parameter and the reference parameter corresponding to the lower capacitor 1311 (formed by a pair of plates C and D) is within a first predetermined range, then it is determined that the loading depth of the aerosol generating substrate 20 is only between plates A and B, and does not reach between plates C and D. If the difference between the signal parameter and the reference parameter corresponding to the upper capacitor 1311 (formed by a pair of plates A and B) is within a second predetermined range, and the difference between the signal parameter and the reference parameter corresponding to the lower capacitor 1311 (formed by a pair of plates C and D) is also within a second predetermined range, then it is determined that the loading depth of the aerosol generating substrate 20 reaches between plates C and D.

[0067] Furthermore, for example, as shown in Figure 6(b), if the difference between the signal parameter and the reference parameter corresponding to the upper target capacitor 1311 (formed by a pair of plates A and C) is within a second predetermined range, and the difference between the signal parameter and the reference parameter corresponding to the lower target capacitor 1311 (formed by a pair of plates B and D) is within a first predetermined range, it is determined that the loading depth of the aerosol generating substrate 20 is only between plates A and B and does not exceed plate B. If the difference between the signal parameter and the reference parameter corresponding to the upper target capacitor 1311 (formed by a pair of plates A and C) is within a second predetermined range, and the difference between the signal parameter and the reference parameter corresponding to the lower target capacitor 1311 (formed by a pair of plates B and D) is also within a second predetermined range, it is determined that the loading depth of the aerosol generating substrate 20 is between plates B and D.

[0068] In the height direction of the substrate 11, the more measurement target capacitors 1311 there are, the more accurately the loading depth of the aerosol generating substrate 20 can be determined. As shown in Figure 6(c), along the height direction of the substrate 11, there are a total of four measurement target capacitors from top to bottom, called the first measurement target capacitor (formed by a pair of plates A and E), the second measurement target capacitor (formed by a pair of plates B and E), the third measurement target capacitor (formed by a pair of plates C and E), and the fourth measurement target capacitor (formed by a pair of plates D and E). If the difference between the signal parameter and reference parameter corresponding to the first capacitor under measurement is within the second predetermined range, the difference between the signal parameter and reference parameter corresponding to the second capacitor under measurement is within the second predetermined range, the difference between the signal parameter and reference parameter corresponding to the third capacitor under measurement is within the second predetermined range, and the difference between the signal parameter and reference parameter corresponding to the fourth capacitor under measurement is within the second predetermined range, then it is determined that the loading depth of the aerosol generating substrate 20 is between plate D and plate E. If the difference between the signal parameter and reference parameter corresponding to the first capacitor under measurement is within the second predetermined range, the difference between the signal parameter and reference parameter corresponding to the second capacitor under measurement is within the second predetermined range, the difference between the signal parameter and reference parameter corresponding to the third capacitor under measurement is within the second predetermined range, and the difference between the signal parameter and reference parameter corresponding to the fourth capacitor under measurement is within the first predetermined range, then it is determined that the loading depth of the aerosol generating substrate 20 is between plate C and plate D. If the difference between the signal parameter corresponding to the first capacitor under measurement and the reference parameter is within the second predetermined range, the difference between the signal parameter corresponding to the second capacitor under measurement and the reference parameter is within the second predetermined range, the difference between the signal parameter corresponding to the third capacitor under measurement and the reference parameter is within the first predetermined range, and the difference between the signal parameter corresponding to the fourth capacitor under measurement and the reference parameter is within the first predetermined range, then it is determined that the loading depth of the aerosol generating substrate 20 is between electrode plate B and electrode plate C.If the difference between the signal parameter corresponding to the first capacitor under measurement and the reference parameter is within the second predetermined range, the difference between the signal parameter corresponding to the second capacitor under measurement and the reference parameter is within the first predetermined range, the difference between the signal parameter corresponding to the third capacitor under measurement and the reference parameter is within the first predetermined range, and the difference between the signal parameter corresponding to the fourth capacitor under measurement and the reference parameter is within the first predetermined range, then it is determined that the loading depth of the aerosol generating substrate 20 is between electrode plate A and electrode plate B.

[0069] Furthermore, as shown in Figure 22, in some embodiments, when the loading depth of the aerosol generating substrate 20 changes from a deep to a shallow depth, the control method may further include step 081 of controlling the heating of the substrate 11 to stop, or step 083 of controlling the heating of the portion of the substrate 11 above the position corresponding to the loading depth and stopping the heating of the portion below that position.

[0070] In this case, the main control unit 17 is configured to stop heating the base body 11 when the loading depth of the aerosol generating substrate 20 changes from a deep position to a shallow position. Alternatively, the main control unit 17 is configured to heat the portion of the base body 11 above the position corresponding to the loading depth and stop heating the portion below that position when the loading depth of the aerosol generating substrate 20 changes from a deep position to a shallow position.

[0071] When the loading depth of the aerosol generating substrate 20 changes from a deep to a shallow depth, it indicates that the aerosol generating substrate 20 loosens and moves upward, eventually being completely withdrawn. If it is completely withdrawn, continuing to heat the base 11 would waste energy, and energy can be saved by controlling the heating of the base 11 to stop. If the aerosol generating substrate 20 is still loaded into the base 11 but moves slightly upward, continuing to heat the entire base 11 would also waste energy. In this case, precise heating can be achieved by controlling the heating of the portion of the base 11 above the position corresponding to the loading depth, and stopping the heating of the portion below that position, thereby saving energy and improving the battery life of the aerosol generator 100.

[0072] As shown in Figure 23, the present invention further provides an aerosol generator 100 including the control module 10 described in any of the above embodiments.

[0073] The aerosol generator 100 of the present invention outputs a high-frequency analog signal by a high-frequency signal generation unit 13, converts the high-frequency analog signal into a measurable signal, measures the signal parameters of the measurable signal, and finally determines whether or not the aerosol generating substrate 20 is loaded into the base body 11 based on the signal parameters and predetermined reference parameters. If it is intelligently determined that the aerosol generating substrate 20 is loaded into the base body 11, the objective of intelligently starting the aerosol generator 100 to heat the aerosol generating substrate 20 can be achieved, and if it is intelligently determined that the aerosol generating substrate 20 is not loaded into the base body 11, the objective of intelligently stopping the aerosol generator 100 can be achieved.
