DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] In order to clarify the purpose, technical solution and advantages of the present application, the present application will be described in detail below with reference to the accompanying drawings and examples. Note that the specific examples described in the present specification are only for the purpose of interpreting the present application, and are not intended to limit the present application.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used herein in the specification of this application are for the purpose of describing particular embodiments only and are not intended to be limiting of the application.

[0030] As can be understood, "connection" in the following examples should be understood as "electrical connection", "communication connection", etc. when the connected circuits, modules, units, etc. have transmission of electrical signals or data with each other.

[0031] In the conventional aerosol generating device, the type of atomization medium needs to be specified rather than inputting a command by a button, which is not convenient to use. In view of this, the present application provides an aerosol generating device and an atomization control device thereof. The tested capacitor module changes capacitance depending on whether the atomization medium is inserted, and the capacitance processing module analyzes the type of the atomization medium according to the capacitance of the tested capacitor module, and identifies the heating control method of the aerosol generating device based on the type of the atomization medium, thereby realizing the automatic adjustment of the heating control method according to the type of the atomization medium without the user needing to operate a button, thereby further improving human-computer interaction (HCI) and user experience. Furthermore, the capacitance processing module analyzes the state of the atomization medium through the capacitance of the capacitor module under test, and performs heating control on the aerosol generating device according to the state of the atomization medium, thereby achieving the purpose of intelligently determining the insertion of the atomization medium and intelligently starting the heating of the atomization medium, and also achieving the purpose of intelligently determining the removal of the atomization medium and intelligently stopping the heating of the atomization medium, i.e., immediately stopping the heating after inhalation. At the same time, it is possible to avoid erroneous heating when there is no atomization medium in the aerosol generating device, and prevent dry burning when there is no atomization medium, so that the device has a certain intelligent safety. In one embodiment, the atomization medium is a solid medium, which generates an aerosol when heated. In some embodiments, the atomization medium includes a tobacco material. The tobacco material includes volatile tobacco flavor compounds that are released from the substrate when heated. The aerosol generating medium may include a non-tobacco material. The solid medium may include substances such as herbaceous plant leaves, tobacco leaves, etc. In other embodiments, the atomizing medium may be a liquid medium that atomizes upon heating to form an aerosol.

[0032] As shown in Fig. 1, in one embodiment, an atomization control device for an aerosol generating device is provided, which includes a capacitor module 100 to be tested and a capacitance processing module 200, and the capacitor plates of the capacitor module 100 to be tested are distributed and installed along the insertion direction of the atomization medium. The capacitance processing module 200 is connected to the capacitor module 100 to be tested. The capacitance of the capacitor module 100 to be tested is changed by inserting the atomization medium, and the capacitance processing module 200 analyzes the type of the atomization medium according to the capacitance of the capacitor module 100 to be tested, and identifies the heating control method of the aerosol generating device according to the type of the atomization medium.

[0033] Specifically, the capacitor module 100 under test may be installed in a cavity of the aerosol generating device for inserting the atomization medium, and when a user inserts the atomization medium into or removes it from the aerosol generating device, the capacitor module 100 under test may generate a change in capacitance according to the position where the atomization medium is actually inserted. The capacitance processing module 200 may store in advance the capacitance of the capacitor module 100 under test when different types of atomization medium are inserted, and when the actual capacitance of the capacitor module 100 under test is detected, the type of the atomization medium currently inserted may be identified, and the heating control method of the aerosol generating device may be adjusted based on the type of the atomization medium. For example, a correspondence relationship between the range of different capacitance value intervals and the type of the atomization medium is established and stored in the capacitance processing module 200. After detecting the actual capacitance value of the capacitor module 100 under test, the capacitance processing module 200 may directly identify the type of the atomization medium according to the capacitance value interval in which the actual capacitance value is located.

[0034] In addition, the specific heating control manner of different types of atomization media is not limited and can be set according to actual needs. The capacitance processing module 200 can also pre-store heating control manners of different types of atomization media, such as heating manners and temperature control manners. When the type of inserted atomization medium is identified, the capacitance processing module 200 can adopt different heating manners and temperature control manners according to the type of different atomization media, thereby improving HCI and user experience.

[0035] In one embodiment, the capacitance processing module 200 further analyzes the state of the atomization medium according to the capacitance of the capacitor module under test, and performs heating control on the aerosol generating device based on the state of the atomization medium. The capacitance processing module 200 may store the initial capacitance value of the capacitor module under test 100 as a comparison threshold in advance, and after detecting the actual capacitance of the capacitor module under test 100, compares it with the comparison threshold to identify whether the atomization medium is inserted or removed, and further performs heating control on the aerosol generating device based on the state of the atomization medium. For example, when the capacitance processing module 200 detects the insertion of the atomization medium, it controls the power supply module to supply power to start heating. When the capacitance processing module 200 further identifies the removal of the atomization medium, it controls the power supply module to cut off the power supply to stop heating.

[0036] The number of capacitor plates in the capacitor module 100 under test is not limited, and may be two or more. For example, when the capacitor module 100 under test includes two capacitor plates, it is possible to identify whether the atomization medium is inserted or removed based on the capacitance of the capacitor module 100 under test. Furthermore, when the capacitor module 100 under test includes three or more capacitor plates, it is possible to identify the position where the atomization medium is currently inserted based on the capacitance of the capacitor module 100 under test, and also to identify whether the atomization medium is inserted or being removed.

[0037] Furthermore, there are no restrictions on the manner in which the capacitance processing module 200 performs heating control on the aerosol generation device based on the state of the nebulization medium, and in one embodiment, when the capacitance processing module 200 identifies the insertion of the nebulization medium based on the capacitance of the capacitor module 100 under test, it controls the aerosol generation device to start heating, and when the capacitance of the capacitor module 100 under test identifies the removal of the nebulization medium, it controls the aerosol generation device to stop heating.

[0038] Furthermore, the number of capacitor plates is three or more, and the capacitance processing module 200 controls the aerosol generating device to start preheating when the atomization medium is being inserted, and controls the aerosol generating device to start heating completely when the atomization medium is fully inserted, and the capacitance processing module 200 further controls the aerosol generating device to end heating early or reduce the heating temperature when the atomization medium is being extracted. Specifically, according to the detected capacitance of the tested capacitor module 100, the capacitance processing module 200 analyzes whether the atomization medium is in an inserted state or an extracted state, and the current actual position of the atomization medium. When the atomization medium is being inserted, the capacitance processing module 200 starts preheating, and when the atomization medium is fully inserted, the heating starts completely. In addition, the power for starting preheating is smaller than the power for starting heating completely, and the specific value can be set according to the actual situation. When the atomization medium is being extracted, the capacitance processing module 200 controls to terminate heating earlier or to lower the heating temperature. Also, if an operation to lower the heating temperature is performed when the atomization medium is being extracted, the capacitance processing module 200 stops heating completely when it determines that the atomization medium is completely extracted.

[0039] The specific configuration of the capacitance processing module 200 is not limited. In one embodiment, the capacitance processing module 200 includes a capacitance collection module 220 and a main control unit 240, and the capacitance collection module 220 is connected to the capacitor module 100 under test and the main control unit 240. The output end of the capacitor module 100 under test is connected to the input end of the capacitance collection module 220, and the capacitance collection module 220 is connected to the input end and the output end of the main control unit 240. The capacitance collection module 220 may specifically be a touch chip, a 555 timer, an RC circuit, or other circuits capable of collecting capacitance. The capacitance collection module 220 converts the change in capacitance into electrical quantities such as voltage, current, resistance, frequency, phase, etc., and processes the electrical quantity data output by the capacitance collection module 220 through the main control unit 240, thereby achieving the purpose of controlling an external device. In addition, in one embodiment, the capacitance collection module 220 may further include a touch chip and a detection circuit, where the touch chip is 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 plate in the capacitor module 100 under test.

[0040] In the atomization control device used in the above-mentioned aerosol generating device, the capacitance of the capacitor module 100 under test is changed when an atomization medium is inserted, and the capacitance processing module 200 analyzes the type of atomization medium based on the capacitance of the capacitor module 100 under test, and identifies the heating control method of the aerosol generating device based on the type of atomization medium, thereby enabling the user to automatically adjust the heating control method according to the type of atomization medium without having to operate a button, thereby improving convenience of use.

[0041] In one embodiment, the capacitor module 100 under test includes a capacitor under test, which is connected to the capacitance processing module 200. The capacitor under test may be designed as a ring-shaped capacitor. Specifically, the capacitor under test may be provided in a cavity in an aerosol generating device into which an atomization medium is inserted. The capacitance processing module 200 detects the actual capacitance value of the capacitor module 100 under test and compares it with a corresponding preset initial capacitance value to determine whether the capacitance value of the capacitor under test has changed, and thus can grasp the current position of the atomization medium, and whether the atomization medium is in an inserted or removed state. Furthermore, the capacitance processing module 200 can directly identify the type of atomization medium according to the capacitance value interval in which the actual capacitance value of the capacitor under test is located.

[0042] The specific configuration of the capacitor under test is not limited, and the material of the substrate of the capacitor under test can be divided into two types of materials, conductive and non-conductive, and the design of the capacitor plate is correspondingly differentiated according to the material of the substrate. In one embodiment, the capacitor under test includes a capacitor plate and a substrate made of a non-conductive material, and the capacitor plate is provided on the substrate, and the number of the capacitor plates is two or more. In the direction of insertion along the atomization medium (e.g., vertical insertion), the two or more capacitor plates are located at different horizontal heights. In addition, the capacitor plate is a closed-loop type plate or a non-closed-loop type plate. Specifically, the substrate may be provided on a hollow cylindrical substrate to accommodate the atomization medium. The capacitor plate is distributed on the substrate in an annular shape, and specifically, is located on the outside or inside of the substrate so as to be distributed vertically along the substrate. In one embodiment, the number of the capacitor plates is two, and the capacitor plate is located on the cylindrical inner wall surface or outer wall surface of the substrate. Specifically, a cylindrical substrate can be designed so that both ends are open, and the capacitor plates can be provided on the cylindrical inner or outer wall surface of the substrate.

[0043] The capacitor plate may be a metal plate, flexible plate, or plated plate. The contour of the annular capacitor plate may be circular, rectangular, arcuate, triangular, spiral, or a combination of these shapes. As shown in FIG. 2, the edges on both sides of the capacitor plate may be one or more segments that are linear, non-linear, planar, or non-planar.

[0044] 3 and 4, the capacitor plate A and the capacitor plate B can be attached to a non-conductive substrate 10 and provided by film plating or electroplating, and the capacitor plate A and the capacitor plate B form a pair of equivalent capacitors. The structure of each capacitor plate may be a closed loop type, a non-closed loop type, or a combination of a closed loop type plate and a non-closed loop type plate.

[0045] Furthermore, the capacitor plates form an annular plate group in a one-to-many or many-to-many manner. For example, when the number of capacitor plates is two, the two capacitor plates form an annular plate group. When the number of capacitor plates is three or more, the annular plate group can be formed in a one-to-many or many-to-many manner. Specifically, a plurality of sets of annular plates may be present on the substrate 10. As a method, it may be one-to-many as shown in FIG. 5, where the capacitor plate A and the capacitor plate B form one set of electrodes, the capacitor plate A and the capacitor plate C form one set of electrodes, and the capacitor plate A and the capacitor plate D form one set of electrodes. It may also be many-to-many as shown in FIG. 6, where the capacitor plate A and the capacitor plate C form one set of electrodes, and the capacitor plate B and the capacitor plate D form one set of electrodes.

[0046] In one embodiment, a 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 other corresponding capacitor plates. The shape of the bottom plate may be rectangular, circular, triangular, arcuate, spiral, or a combination of these shapes, and is not limited. As shown in FIG. 7, there is one bottom plate E at the bottom of the base 10, and the bottom plate E forms one or more pairs of equivalent capacitors with the annular capacitor plate. For example, as shown in FIG. 7, the capacitor plate A and the bottom plate E form one pair of equivalent capacitors, or as shown in FIG. 8, the capacitor plate A and the bottom plate E form one pair of equivalent capacitors, the capacitor plate B and the bottom plate E form one pair of equivalent capacitors, the capacitor plate C and the bottom plate E form one pair of equivalent capacitors, and the capacitor plate D and the bottom plate E form one pair of equivalent capacitors.

[0047] In one embodiment, the number of capacitor plates is two, 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 a 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 the atomization medium is inserted, and the structure is simple.

[0048] In addition, 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 atomization medium.

[0049] In one embodiment, as shown in Fig. 9, the capacitor plate includes an annular portion and an extension portion provided on the annular portion, the number of the capacitor plates is two, and the extension portions of the two capacitor plates are arranged opposite to each other. Specifically, two capacitor plates A and B are designed to have a structure in which an annular portion and an extension portion are combined, the extension portion of the capacitor plate is provided on the annular portion and perpendicular to the curved surface on which the annular portion is located, and the extension portions of the two capacitor plates are arranged opposite to each other. By detecting the actual capacitance value of the two capacitor plates, the state of the atomization medium can be identified in the same way.

[0050] As shown in FIG. 10, in another embodiment, the capacitor under test includes a conductive substrate 10, which is divided into two or more capacitor plates, specifically, three capacitor plates. The capacitor plates are arranged in a one-to-many or many-to-many manner to form an annular plate group. 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 a plurality of annular capacitor plates, and as shown in FIG. 10 and FIG. 11, the capacitor plates A and B into which the substrate 10 is divided form a pair of equivalent capacitors, and each of the capacitor plates is an annular capacitor plate, and may be a closed loop type or a non-closed loop type, or may be any combination of a closed loop type plate and a non-closed loop type plate. The capacitor plates A and B are both made of a metal material, and receive the atomization medium and generate heat due to an external alternating magnetic field to heat the atomization medium. The capacitor under test further includes an insulating member provided between the capacitor plates. For example, an insulating member 20 is provided between the capacitor plates A and B, and the insulating member 20 may be made of ceramics. In this embodiment, the capacitor plates and the insulating member 20 are hollow so as to accommodate the atomization medium in cooperation with each other.

[0051] Furthermore, the capacitor plates into which the base 10 is divided form a plurality of sets of annular plates. As a method, it may be a one-to-many type as shown in Fig. 12, where capacitor plate A and capacitor plate B form a set of electrodes, capacitor plate A and capacitor plate C form a set of electrodes, and capacitor plate A and capacitor plate D form a set of electrodes. It may also be a many-to-many type as shown in Fig. 13, where capacitor plate A and capacitor plate C form a set of electrodes, and capacitor plate B and capacitor plate D form a set of electrodes.

[0052] Correspondingly, in one embodiment, one capacitor plate also separated from the base 10 may be the bottom plate of the base 10, and the bottom plate forms an equivalent capacitor with the corresponding other capacitor plate. The shape of the bottom plate may also be rectangular, circular, triangular, arcuate, spiral, and combinations of these shapes. As shown in FIG. 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 plate. For example, as shown in FIG. 14, the capacitor plate A and the bottom plate E form one equivalent capacitor set, or as shown in FIG. 15, the capacitor plate A and the bottom plate E form one equivalent capacitor set, the capacitor plate B and the bottom plate E form one equivalent capacitor set, the capacitor plate C and the bottom plate E form one equivalent capacitor set, and the capacitor plate D and the bottom plate E form one equivalent capacitor set.

[0053] Fig. 16 is a schematic diagram of the atomization medium X inserted into the base. The atomization medium X is regarded as equivalent to one electrode plate of a capacitor, and the capacitor electrode plate A and the atomization medium X form a capacitor (1), and the capacitor electrode plate B and the atomization medium X form a capacitor (2). The schematic diagram of the formed equivalent capacitor is shown in Fig. 17. The theoretical formula of the capacitance is as follows:

[0054]

number

[0055] where C is the capacitance value, ε is the dielectric constant between the capacitor plates, S is the plate area, and d is the distance between the plates. Since the conductivity of the atomization medium X is much smaller than that of the capacitor plates A and B, the atomization medium X being inserted between the capacitor plates A and B is equivalent to changing the dielectric constant ε of the material between the capacitor plates A and B. Thus, the capacitance between the capacitor plates A and B changes. Depending on whether the capacitance between the capacitor plates A and B has changed, it can be identified whether the atomization medium X is inserted between the capacitor plates A and B. The atomization medium X may also be a cigarette, a solid drug, or other solid substance. The atomization medium X may also be a liquid substance contained in a solid container.

[0056] Furthermore, in the above theoretical capacitance formula, the plate area S and plate distance d in the atomizer are fixed, and the dielectric constant of different atomization media is different, so the values ​​of the tested capacitor are also different. By collecting capacitance values ​​and setting the capacitance value ranges of different materials, different atomization media can be identified. For example, the following formula:

number

[0057] If it is known that ε1>ε2, then C1>C2, and if it is known that ε1<ε2, then C1 <C2になる。

[0058] By providing a plurality of annular capacitor plates, for example, three or four, when the atomization medium reaches the position of a certain annular capacitor plate, it is possible to measure the change in capacitance of the annular capacitor plate at the corresponding position, and further to identify the position of the atomization medium. Based on this characteristic, heating can be started by acquiring the insertion state and position of the atomization medium, and heating can be stopped by acquiring the removal state and position of the atomization medium. For example, as shown in FIG. 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 atomization medium is inserted at position B in Fig. 18-(1), the capacitance of capacitor plate A and capacitor plate B changes, when the atomization medium is inserted at position C in Fig. 18-(2), the capacitance of capacitor plate A and capacitor plate C changes, and when the atomization medium is inserted at position D in Fig. 18-(3), the capacitance of capacitor plate A and capacitor plate D changes.

[0061] Taking the touch chip 222 as an example of the capacitance collection module 220, the principle of capacitance scanning of the touch chip 222 can be divided into mutual capacitance scanning and self-capacitance scanning. The self-capacitance scanning is a self-transmitting and self-receiving scanning method, and the capacitance measured by the touch chip 222 is the capacitance between an electrode and a ground. In the mutual capacitance scanning, the touch chip 222 measures the capacitance between two electrodes. According to 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 types of methods. As shown in FIG. 24, in the self-capacitance scanning method, one plate of the capacitor under test in the capacitor module 100 under test is connected to the ground, and the other plate is connected to the signal collection input terminal of the touch chip 222. As shown in FIG. 25, for the mutual capacitance scanning method, one plate of the capacitor under test in the capacitor module under test 100 is connected to the signal output terminal of the touch chip 222, and the other plate is connected to the signal collection input terminal of the touch chip 222.

[0062] The touch chip 222 periodically collects and updates the initial capacitance value of the capacitor module 100 under test, and the initial capacitance value is set as the threshold value at which the capacitance changes. When the atomization medium is inserted or removed, the touch chip collects the capacitance value changes of each set of annular plates. The main control unit 240 can analyze and obtain the position of the atomization medium, whether it is inserted or removed, according to the capacitance value detected by the touch chip 222.

[0063] In addition, the main control unit 240 includes a control chip and discrete components. The control chip is used to collect data information of the touch chip 222 and perform control operations according to the data information of the touch chip 222. The discrete components include a power chip, resistors, capacitors, inductors, crystal oscillators, memories, logic gate circuits, etc., which support the operation of the control chip. When the atomization medium is inserted, the touch chip 222 can identify 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 realize the early start of pre-heating. When the atomization medium is inserted, the touch chip 222 can identify the fully inserted state by the change in capacitance of the annular capacitor plate at a specific position, and the main control unit 240 can fully start heating. Furthermore, by setting different capacitance value ranges of solid atomization medium, the touch chip 222 identifies the solid atomization medium according to the collected capacitance value, and the main control unit 240 uses different heating control methods, for example, adjusts the heating and temperature control methods to be corresponding to the identified solid atomization medium when heating is fully started. Also, by setting different capacitance value ranges of liquid atomization medium, the touch chip 222 identifies the liquid atomization medium according to the collected capacitance value, and the main control unit 240 uses different heating and temperature control methods, for example, adjusts the heating and temperature control methods to be corresponding to the identified liquid atomization medium when heating is fully started.

[0064] When the atomization medium is extracted, the touch chip 222 can identify the gradually extracted state by the change of the capacitance of the annular capacitor plate at a specific position, and the main control unit 240 can realize to terminate heating early or reduce the heating temperature. When the atomization medium is extracted, the touch chip 222 can identify the completely extracted state by the change of the capacitance of the annular capacitor plate at a specific position, and the main control unit 240 can completely stop heating.
