[0026] To further clarify the purpose, technical solution, and advantages of this application, the application will be described in detail below with reference to the attached drawings and examples. The specific examples described herein are for interpretation purposes only and are not intended to limit the application.

[0027] Conventional aerosol generators typically initiate heating using a button, resulting in low user convenience. In view of this, the present invention provides an aerosol generator and its sensitive control device. The condenser module under test changes its capacitance depending on whether an atomizing medium is inserted. The capacitance processing module analyzes the state of the atomizing medium based on the capacitance of the condenser module under test and controls heating of the aerosol generator based on the state of the atomizing medium. This intelligently determines whether an atomizing medium has been inserted and starts heating the atomizing medium, and also intelligently determines whether an atomizing medium has been removed and stops heating the atomizing medium. In other words, heating can be stopped immediately after inhalation. At the same time, it avoids erroneous heating when there is no atomizing medium in the aerosol generator and prevents dry heating due to the absence of an atomizing medium, thus providing a certain level of intelligent safety. In one embodiment, the atomizing medium is a solid medium that generates an aerosol when heated. Preferably, the atomizing medium contains tobacco material. The tobacco material contains volatile tobacco-flavored compounds released from the substrate upon heating. The aerosol-generating medium may also contain non-tobacco materials. The solid medium may contain substances such as herbaceous plant leaves or tobacco leaves. In other embodiments, the atomizing medium may be a liquid medium that atomizes after heating to form an aerosol.

[0028] As shown in Figure 1, in one embodiment, a sensitive control device for an aerosol generator is provided, which includes a capacitor module under test 100 and a capacitance processing module 200, wherein the capacitor plates of the capacitor module under test 100 are arranged to be distributed along the insertion direction of the atomizing medium. The capacitance processing module 200 is connected to the capacitor module under test 100. The capacitance of the capacitor module under test 100 changes when the atomizing medium is inserted, and the capacitance processing module 200 analyzes the state of the atomizing medium based on the capacitance of the capacitor module under test 100 and performs heating control on the aerosol generator based on the state of the atomizing medium.

[0029] Specifically, the capacitor module under test 100 may be installed in the cavity of the aerosol generator into which the atomizing medium is inserted. When a user inserts or removes the atomizing medium from the aerosol generator, the capacitor module under test 100 can generate a change in capacitance depending on the position where the atomizing medium is actually inserted. The capacitance processing module 200 may store the initial capacitance value of the capacitor module under test 100 as a comparison threshold in advance. After detecting the actual capacitance of the capacitor module under test 100, it compares it with the comparison threshold to determine whether the atomizing medium is inserted or removed, and then performs heating control on the aerosol generator based on the state of the atomizing medium. For example, when the capacitance processing module 200 detects the insertion of the atomizing medium, it controls the power supply module to supply power and start heating. Furthermore, when the capacitance processing module 200 identifies the removal of the atomizing medium, it controls the power supply module to cut off the power supply and stop heating.

[0030] Furthermore, there is no limit to the number of capacitor plates in the capacitor module 100 under test; it may be two or three or more. For example, if the capacitor module 100 under test contains two capacitor plates, the capacitance of the capacitor module 100 can be used to determine whether the atomizing medium has been inserted or removed. Moreover, if the capacitor module 100 under test contains three or more capacitor plates, the capacitance of the capacitor module 100 can be used to determine the current position where the atomizing medium is inserted, and whether it is inserted or in the process of being removed.

[0031] Furthermore, there are no limitations on how the capacitance processing module 200 controls heating for the aerosol generator based on the state of the atomizing medium. In one embodiment, the capacitance processing module 200 controls the aerosol generator to start heating when it detects the insertion of the atomizing medium based on the capacitance of the capacitor module 100 under test, and controls the aerosol generator to stop heating when it detects the removal of the atomizing medium based on the capacitance of the capacitor module 100 under test.

[0032] Furthermore, the number of capacitor plates is three or more, and the capacitance processing module 200 controls the aerosol generator to start preheating when the atomizing medium is being inserted, and to start heating completely when the atomizing medium is fully inserted. The capacitance processing module 200 also controls the aerosol generator to either end heating early or lower the heating temperature when the atomizing medium is being removed. Specifically, based on the detected capacitance of the capacitor module 100 under test, the capacitance processing module 200 analyzes whether the atomizing medium is in an inserted or removed state and its current actual position. Preheating is started when the atomizing medium is being inserted, and heating is started completely when the atomizing medium is fully inserted. In addition, the power required to start preheating is less than the power required to start heating completely, and the specific value can be set according to the actual situation. While the atomizing medium is being extracted, the capacitance processing module 200 controls the heating to either terminate it earlier or lower the heating temperature. If the heating temperature is lowered while the atomizing medium is being extracted, the capacitance processing module 200 will identify that the atomizing medium has been completely extracted and will stop heating completely.

[0033] The specific configuration of the capacitance processing module 200 is not limited. In one embodiment, the capacitance processing module 200 includes a capacitance acquisition module 220 and a main control unit 240, where the capacitance acquisition module 220 is connected to the capacitor module under test 100 and the main control unit 240. The output terminal of the capacitor module under test 100 is connected to the input terminal of the capacitance acquisition module 220, and the capacitance acquisition module 220 is connected to the input and output terminals of the main control unit 240. The capacitance acquisition module 220 may specifically be a touch chip, a 555 timer, an RC circuit, or other circuit capable of acquiring capacitance. The capacitance acquisition module 220 converts the change in capacitance into electrical quantities such as voltage, current, resistance, frequency, and phase, and the main control unit 240 processes the electrical quantity data output by the capacitance acquisition module 220, thereby achieving the objective of controlling an external device. In one embodiment, the capacitance collection module 220 may further include a touch chip and a detection circuit, the touch chip being connected to the capacitor module 100 under test via the detection circuit, and the detection circuit may specifically include a capacitor to be connected in series or parallel to the capacitor plates in the capacitor module 100 under test.

[0034] In the above-described sensor control device for the aerosol generator, the capacitance of the capacitor module 100 under test changes when an atomizing medium is inserted. The capacitance processing module 200 analyzes the state of the atomizing medium based on the capacitance of the capacitor module under test and performs heating control on the aerosol generator based on the state of the atomizing medium. This eliminates the need for the user to press a button to start heating the aerosol generator, as the heating control is automatically performed according to the state of the atomizing medium, thereby improving ease of use.

[0035] In one embodiment, the capacitor under test module 100 includes a capacitor under test, which is connected to a capacitance processing module 200. The capacitor under test may be designed as a ring-shaped capacitor. Specifically, the capacitor under test can be placed in a cavity in an aerosol generator into which an atomizing medium is inserted. The capacitance processing module 200 can detect the actual capacitance value of the capacitor under test module 100 and compare it with a corresponding preset initial capacitance value to determine whether the capacitance value of the capacitor under test has changed, thereby allowing the module to determine the current position of the atomizing medium and whether the atomizing medium is inserted or removed.

[0036] The specific configuration of the capacitor under test is not limited, and the substrate material of the capacitor under test can be divided into two types: conductive and non-conductive. The design of the capacitor plates is also correspondingly distinguished according to the substrate material. In one embodiment, the capacitor under test includes capacitor plates and a substrate made of a non-conductive material, the capacitor plates are provided on the substrate, and there are two or more capacitor plates. In the direction of insertion of the atomizing medium (for example, when inserted vertically), the two or more capacitor plates are located at different horizontal heights. The capacitor plates are either closed-loop type plates or open-loop type plates. Specifically, the substrate may be a hollow cylindrical substrate for housing the atomizing medium. The capacitor plates are distributed in an annular shape on the substrate, specifically located on the outside or inside of the substrate so as to be distributed longitudinally along the substrate. In one embodiment, there are two capacitor plates, and the capacitor plates are located on the inner or outer cylindrical wall surface of the substrate. Specifically, a cylindrical base can be designed with openings at both ends, and capacitor plates can be mounted on the inner or outer cylindrical wall surface of the base.

[0037] Furthermore, metal plates may be used for the capacitor plates, and these plates may be flexible or plated. The outer contour of the annular capacitor plate may be circular, rectangular, arched, triangular, spiral, or a combination of these shapes. Also, as shown in Figure 2, the edges on both sides of the capacitor plate may be linear, nonlinear, planar, or non-planar segments, one or more segments.

[0038] As shown in Figures 3 and 4, capacitor plates A and B can be bonded to a non-conductive substrate 10 and provided by film plating or electroplating, and capacitor plates A and B constitute a pair of equivalent capacitors. The structure of each capacitor plate may be a closed-loop type, an open-loop type, or a combination of a closed-loop type plate and an open-loop type plate.

[0039] Furthermore, the capacitor plates can form an annular group of plates in a one-to-many or many-to-many manner. For example, if there are two capacitor plates, the two capacitor plates form an annular group of plates. If there are three or more capacitor plates, the annular group of plates can be formed in a one-to-many or many-to-many manner. Specifically, there may be multiple sets of annular plates on the substrate 10. As shown in Figure 5, the arrangement may be one-to-many, where capacitor plate A and capacitor plate B form one set of electrodes, capacitor plate A and capacitor plate C form one set of electrodes, and capacitor plate A and capacitor plate D form one set of electrodes. Alternatively, as shown in Figure 6, the arrangement may be many-to-many, where capacitor plate A and capacitor plate C form one set of electrodes, and capacitor plate B and capacitor plate D form one set of electrodes.

[0040] In one embodiment, an additional capacitor plate may be provided at the bottom of the base 10 as a bottom plate. The bottom plate forms an equivalent capacitor with the corresponding other capacitor plates. The shape of the bottom plate is not limited and may be rectangular, circular, triangular, arched, spiral, or a combination of these shapes. As shown in Figure 7, one bottom plate E is present at the bottom of the base 10, and the bottom plate E forms one or more equivalent capacitors with the annular capacitor plates. For example, as shown in Figure 7, capacitor plate A and bottom plate E constitute one equivalent capacitor, or as shown in Figure 8, capacitor plate A and bottom plate E constitute one equivalent capacitor, capacitor plate B and bottom plate E constitute one equivalent capacitor, capacitor plate C and bottom plate E constitute one equivalent capacitor, and capacitor plate D and bottom plate E constitute one equivalent capacitor.

[0041] In one embodiment, there are two capacitor plates, one end of the base 10 is sealed to form a bottom wall, and one of the capacitor plates is provided on the bottom wall of the base 10. Specifically, two capacitor plates are provided vertically inside the base 10, and one of the capacitor plates is located on the bottom wall of the base 10 and serves as the bottom plate. The other capacitor plate is located on the side wall of the base 10. By combining the two capacitor plates, it is possible to detect whether or not an atomizing medium has been inserted, and the structure is simple.

[0042] Furthermore, the capacitor under test may further include a heating element provided on the substrate 10. The heating element can be specifically obtained by printing a resistive heating circuit on the substrate 10 and is used to heat the atomizing medium.

[0043] In one embodiment, as shown in Figure 9, the capacitor plate includes an annular portion and an extended portion provided on the annular portion, and there are two capacitor plates, with the extended portions of the two capacitor plates positioned opposite each other. Specifically, the two capacitor plates A and B are designed with a structure in which the annular portion and the extended portion are connected, the extended portion of the capacitor plate is provided on the annular portion and is perpendicular to the plane in which the annular portion is located, and the extended portions of the two capacitor plates are positioned opposite each other. By detecting the actual capacitance values ​​of the two capacitor plates, the state of the atomizing medium can be similarly identified.

[0044] As shown in Figure 10, in other embodiments, the capacitor under test includes a conductive substrate 10, which is divided into two or more capacitor plates, specifically into three capacitor plates. The capacitor plates are arranged in a one-to-many or many-to-many configuration to form an annular group of plates. Specifically, when a conductive material is used for the substrate 10, the substrate 10 functions as both a heating element and a capacitor plate. The substrate 10 is divided into multiple annular capacitor plates, and as shown in Figures 10 and 11, the divided capacitor plates A and B of the substrate 10 constitute a pair of equivalent capacitors. Each capacitor plate is an annular capacitor plate and may be of a closed-loop type, an open-loop type, or any combination of a closed-loop plate and an open-loop plate. Capacitor plates A and B are made of metal and receive the atomizing medium, generating heat from an external alternating magnetic field to heat the atomizing medium. Furthermore, the capacitor under test includes an insulating member provided between the capacitor plates. For example, an insulating member 20 may be provided between capacitor plate A and capacitor plate B, and ceramics may be specifically used for the insulating member 20. In this embodiment, the capacitor plates and the insulating member 20 are hollow in order to cooperate in accommodating the atomizing medium.

[0045] Furthermore, the capacitor plates separated from the substrate 10 constitute multiple sets of annular plates. As shown in Figure 12, the arrangement may be one-to-many, where capacitor plate A and capacitor plate B constitute one set of electrodes, capacitor plate A and capacitor plate C constitute one set of electrodes, and capacitor plate A and capacitor plate D constitute one set of electrodes. Alternatively, as shown in Figure 13, the arrangement may be many-to-many, where capacitor plate A and capacitor plate C constitute one set of electrodes, and capacitor plate B and capacitor plate D constitute one set of electrodes.

[0046] Correspondingly, in one embodiment, one capacitor plate similarly separated from the base 10 may also be the bottom plate of the base 10, and the bottom plate forms an equivalent capacitor with the corresponding other capacitor plates. The shape of the bottom plate may similarly be rectangular, circular, triangular, arched, spiral, or a combination of these shapes. As shown in Figure 14, there is one bottom plate E at the bottom of the base 10, and the bottom plate E forms one or more equivalent capacitors with the annular capacitor plates. For example, as shown in Figure 14, capacitor plate A and bottom plate E constitute one equivalent capacitor, or as shown in Figure 15, capacitor plate A and bottom plate E constitute one equivalent capacitor, capacitor plate B and bottom plate E constitute one equivalent capacitor, capacitor plate C and bottom plate E constitute one equivalent capacitor, and capacitor plate D and bottom plate E constitute one equivalent capacitor.

[0047] Figure 16 shows a schematic diagram in which the atomizing medium X is inserted into the substrate. The atomizing medium X is considered equivalent to one plate of a capacitor, and capacitor plate A and atomizing medium X form capacitor (1), and capacitor plate B and atomizing medium X form capacitor (2). A schematic diagram of the formed equivalent capacitor is shown in Figure 17. The theoretical formula for capacitance is as follows.

[0048]

number

[0049] For example, by providing three or four or more annular capacitor plates, when the atomizing medium reaches the position of an annular capacitor plate, it is possible to measure that the capacitance of the annular capacitor plate at the corresponding position has changed, and furthermore, the position of the atomizing medium can be identified. Based on this characteristic, heating can be started by acquiring the insertion operation and position of the atomizing medium, and heating can be stopped by acquiring the removal operation and position of the atomizing medium. For example, as shown in Figure 18, capacitor plate A and capacitor plate B are a pair of capacitors, capacitor plate A and capacitor plate C are a pair of capacitors, and capacitor plate A and capacitor plate D are a pair of capacitors. When the atomizing medium is inserted at position B in Figure 18-(1), the capacitances of capacitor plates A and B change. When the atomizing medium is inserted at position C in Figure 18-(2), the capacitances of capacitor plates A and C change. When the atomizing medium is inserted at position D in Figure 18-(3), the capacitances of capacitor plates A and D change. This characteristic allows us to obtain positional information for the insertion of the atomizing medium.

[0050] Depending on the combination method of the capacitor module 100 under test, the capacitor module 100 under test can be divided into two types: independent test modules and coupled test modules. The coupled test module can be divided into series type and parallel type. As shown in Figure 19, the independent test module tests only the capacitor body under test, where Cx is the capacitor plate. For the series type of coupled test module, as shown in Figure 20, capacitors C1 and C2 are external test capacitors connected in series to the capacitor plate Cx, and capacitors C1 and C2 are specifically capacitors within the capacitance collection module 220. The number of capacitors connected in series is not limited and may be one, two, or more, and can be adjusted according to the actual demand. Furthermore, the capacitors connected in series may be finished capacitors produced by the capacitor manufacturer, or they may be capacitors made of structural components.

[0051] Furthermore, for the parallel type of coupled test module, as shown in Figure 21, capacitors C1 and C2 are external test capacitors connected in parallel to the capacitor plate Cx, and capacitors C1 and C2 are specifically capacitors within the capacitance collection module 220. The number of capacitors connected in parallel is not limited and may be one, two, or more, and can be adjusted according to the actual demand. The capacitors connected in parallel may be finished capacitors produced by the capacitor manufacturer, or they may be capacitors made of structural components. As shown in Figure 22, for the parallel and series type coupled test modules, capacitors C1 and C2 are external test capacitors connected in parallel to the capacitor plate Cx, and capacitors C3 and C4 are external test capacitors connected in series to the capacitor plate Cx, and capacitors C1, C2, C3, and C4 are specifically capacitors within the capacitance collection module 220. The number of capacitors connected in parallel is not limited and may be one, two, or more, and can be adjusted according to the actual demand. The capacitors connected in parallel may be finished capacitors produced by the capacitor manufacturer, or they may be capacitors made from structural components. The number of capacitors connected in series is not limited and may be one, two, or more, and can be adjusted according to the specific actual demand. The capacitors connected in series may be finished capacitors produced by the capacitor manufacturer, or they may be capacitors made from structural components.

[0052] Taking the example of using a touch chip 222 as the capacitance acquisition module 220, the capacitance scanning principle of the touch chip 222 can be divided into mutual capacitance scanning and self-capacitance scanning. Self-capacitance scanning is a self-transmitting, self-receiving scanning method, and the capacitance measured by the touch chip 222 is the capacitance between the electrode and the ground. In the case of mutual capacitance scanning, the touch chip 222 measures the capacitance between the two electrodes. Depending on the different capacitance scanning methods of the touch chip, the connection between the touch chip 222 and the capacitor module 100 under test can be divided into the following two methods. As shown in Figure 23, in the self-capacitance scanning method, one plate of the capacitor under test in the capacitor module 100 is connected to ground, and the other plate is connected to the signal acquisition input terminal of the touch chip 222. As shown in Figure 24, in the mutual capacitance scan method, one plate of the capacitor under test in the capacitor module 100 is connected to the signal output terminal of the touch chip 222, and the other plate is connected to the signal acquisition input terminal of the touch chip 222.

[0053] The touch chip 222 periodically collects and updates the initial capacitance value of the capacitor module 100 under test, thereby setting the initial capacitance value as the threshold at which the capacitance changes. When the atomizing medium is inserted and removed, the touch chip collects the change in capacitance value of each set of annular plates. The main control unit 240 can analyze the position, insertion state, and removal state of the atomizing medium based on the capacitance value detected by the touch chip 222.

[0054] Furthermore, the main control unit 240 includes a control chip and discrete components. The control chip is used to collect data information from the touch chip 222 and to perform control operations based on the data information from the touch chip 22. The discrete components include a power supply chip, resistors, capacitors, inductors, a crystal oscillator, memory, and logic gate circuits that support the operation of the control chip. When the atomizing medium is inserted, the touch chip 222 identifies the gradually inserted state by the change in capacitance of the annular capacitor plate at a specific position, and the main control unit 240 can start preheating earlier. When the atomizing medium is inserted, the touch chip 222 identifies the fully inserted state by the change in capacitance of the annular capacitor plate at a specific position, and the main control unit 240 starts heating completely. When the atomizing medium is withdrawn, the touch chip 222 identifies the gradual withdrawal state by the change in capacitance of the annular capacitor plate at a specific position, and the main control unit 240 can either terminate heating earlier or reduce the heating temperature. When the atomizing medium is withdrawn, the touch chip 222 identifies the state of complete withdrawal by the change in capacitance of the annular capacitor plate at a specific position, and the main control unit 240 completely stops heating.

[0055] In one embodiment, an aerosol generating device is provided, which includes the above-mentioned sensor control device.

[0056] In the above-described aerosol generator, the capacitance of the condenser module under test changes when the atomizing medium is inserted. The capacitance processing module analyzes the state of the atomizing medium based on the capacitance of the condenser module under test and controls the heating of the aerosol generator based on the state of the atomizing medium. This eliminates the need for the user to press a button to start heating of the aerosol generator, as the heating is automatically controlled according to the state of the atomizing medium, thus improving ease of use.
