[0053] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0054] 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 terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

[0055] It can be understood that "connection" in the following embodiments should be understood as "electrical connection", "communication connection" and the like if the circuits, modules, units and the like to be connected have electrical signal or data transmission between each other.

[0056] The conventional aerosol generating device needs to input instructions through a button to determine the type of atomization medium, and the convenience of use is low. Based on this, the present application provides an aerosol generating device and an atomization control device thereof. The to-be-tested capacitor assembly generates a change in capacitance according to whether the atomization medium is inserted. The capacitance processing assembly analyzes the type of atomization medium according to the capacitance of the to-be-tested capacitor assembly, and determines the heating control mode of the aerosol generating device according to the type of atomization medium, so as to automatically adjust the heating control mode in combination with the type of atomization medium, without the need for the user to operate through a button, thereby enhancing the human-computer interaction and the experience of the user. In addition, the capacitance processing assembly also analyzes the state of the atomization medium according to the capacitance of the to-be-tested capacitor assembly, and controls the heating of the aerosol generating device according to the state of the atomization medium, so as to intelligently judge the insertion of the atomization medium, achieve the purpose of intelligently starting to heat the atomization medium, and intelligently judge the pulling out of the atomization medium, achieve the purpose of intelligently stopping heating the atomization medium, i.e. puffing and stopping. At the same time, it can avoid the false heating of the aerosol generating device when there is no atomization medium in the aerosol generating device, prevent dry burning when there is no atomization medium, and have certain intelligent safety. In one embodiment, the atomization medium is a solid medium, which is used to generate aerosol when heated, and the atomization medium preferably includes a tobacco-containing material containing volatile tobacco flavor compounds released from the substrate when heated. The aerosol generating substrate can include a non-tobacco material. The solid medium can contain herbal plant leaves, tobacco leaves and the like. In other embodiments, the atomization medium can also be a liquid medium, which is atomized to form an aerosol after being heated.

[0057] In one embodiment, as Figure 1As shown, an atomization control device of an aerosol generating device is provided, including a to-be-tested capacitor assembly 100 and a capacitance processing assembly 200. The capacitor plates of the to-be-tested capacitor assembly 100 are arranged along the insertion direction of the atomization medium. The capacitance processing assembly 200 is connected to the to-be-tested capacitor assembly 100. The to-be-tested capacitor assembly 100 generates a capacitance change according to whether the atomization medium is inserted. The capacitance processing assembly 200 analyzes the type of the atomization medium according to the capacitance of the to-be-tested capacitor assembly 100, and determines the heating control mode of the aerosol generating device according to the type of the atomization medium.

[0058] Specifically, the to-be-tested capacitor assembly 100 can be arranged at a cavity of the aerosol generating device for inserting the atomization medium. When the user inserts or removes the atomization medium into or from the aerosol generating device, the to-be-tested capacitor assembly 100 can generate a capacitance change according to the actual insertion position of the atomization medium. The capacitance processing assembly 200 can pre-store the capacitance of the to-be-tested capacitor assembly 100 when different types of atomization medium are inserted. After detecting the actual capacitance of the to-be-tested capacitor assembly 100, the type of the currently inserted atomization medium can be determined, and then the heating control mode of the aerosol generating device can be adjusted according to the state of the atomization medium. For example, a corresponding relationship between different capacitance value interval ranges and the types of the atomization medium is established and stored in the capacitance processing assembly 200. After detecting the actual capacitance value of the to-be-tested capacitor assembly 100, the capacitance processing assembly 200 can directly determine the type of the atomization medium according to the actual capacitance value interval in which the actual capacitance value is located.

[0059] Further, the specific heating control mode of different types of atomization medium is not unique and can be set according to actual needs. The capacitance processing assembly 200 can also pre-store the heating control mode of different types of atomization medium, such as heating mode and temperature control mode. After identifying the type of the inserted atomization medium, the capacitance processing assembly 200 can adopt different heating and temperature control modes according to different atomization media, thereby enhancing human-computer interaction and human experience.

[0060] In one embodiment, the capacitance processing assembly 200 is further configured to analyze the state of the atomization medium according to the capacitance of the to-be-tested capacitor assembly, and to control the heating of the aerosol generating device according to the state of the atomization medium. The capacitance processing assembly 200 can pre-store the initial capacitance value of the to-be-tested capacitor assembly 100 as a comparison threshold. After detecting the actual capacitance of the to-be-tested capacitor assembly 100, the comparison threshold is compared to determine whether the atomization medium is in an inserted state or a removed state, and then the heating of the aerosol generating device is controlled according to the state of the atomization medium. For example, the capacitance processing assembly 200 controls the power supply module to supply power to turn on the heating when detecting that the atomization medium is inserted. The capacitance processing assembly 200 also controls the power supply module to cut off power to turn off the heating when identifying that the atomization medium is removed.

[0061] The number of the capacitor plates in the to-be-tested capacitor assembly 100 is not unique, and can be two, three, or more than three. For example, when the to-be-tested capacitor assembly 100 contains two capacitor plates, the insertion or removal state of the atomization medium can be identified according to the capacitance of the to-be-tested capacitor assembly 100. Further, when the to-be-tested capacitor assembly 100 contains three or more than three capacitor plates, the current insertion position of the atomization medium and the insertion or removal state of the atomization medium can be identified according to the capacitance of the to-be-tested capacitor assembly 100.

[0062] It can be understood that the manner in which the capacitance processing assembly 200 controls the heating of the aerosol-generating device according to the state of the atomization medium is not unique. In one embodiment, the capacitance processing assembly 200 controls the aerosol-generating device to start heating when the atomization medium is inserted, and controls the aerosol-generating device to stop heating when the atomization medium is removed, according to the capacitance of the to-be-tested capacitor assembly 100.

[0063] Further, when the number of the capacitor plates is three or more than three, the capacitance processing assembly 200 controls the aerosol-generating device to start preheating when the atomization medium is in the insertion state, and controls the aerosol-generating device to start full heating when the atomization medium is fully inserted. The capacitance processing assembly 200 also controls the aerosol-generating device to end heating or reduce the heating temperature in advance when the atomization medium is in the removal state. Specifically, according to the detected capacitance of the to-be-tested capacitor assembly 100, the capacitance processing assembly 200 analyzes whether the atomization medium is in the insertion or removal state, and the current actual position of the atomization medium. The preheating is started when the atomization medium is in the insertion state, and the full heating is started when the atomization medium is fully inserted. The power of the preheating is less than the power of the full heating, and the specific value can be set according to the actual situation. When the atomization medium is in the removal state, the capacitance processing assembly 200 also controls the aerosol-generating device to end heating or reduce the heating temperature in advance. In addition, if the heating temperature is reduced when the atomization medium is in the removal state, the capacitance processing assembly 200 fully stops the heating when the atomization medium is fully removed.

[0064] The specific structure of the capacitance processing assembly 200 is also not unique. In an embodiment, the capacitance processing assembly 200 includes a capacitance collection assembly 220 and a master control unit 240, and the capacitance collection assembly 220 is connected to the to-be-measured capacitance assembly 100 and the master control unit 240. The output end of the to-be-measured capacitance assembly 100 is connected to the input end of the capacitance collection assembly 220, and the capacitance collection assembly 220 is connected to the input end and the output end of the master control unit 240. The capacitance collection assembly 220 can specifically adopt a touch chip, a 555 timer, an RC circuit, or other circuits that can collect capacitance. The capacitance collection assembly 220 converts the capacitance change into an electrical quantity such as voltage, current, resistance, frequency, phase, etc., and then the master control unit 240 processes the electrical quantity data output by the capacitance collection assembly 220, so as to achieve the purpose of controlling the external device. In addition, in an embodiment, the capacitance collection assembly 220 can also include a touch chip and a detection circuit, and the touch chip is connected to the to-be-measured capacitance assembly 100 through the detection circuit. The detection circuit can specifically include a capacitor used in series or parallel with the capacitor plate in the to-be-measured capacitance assembly 100.

[0065] The above-mentioned atomization control device of the aerosol generating device. The to-be-measured capacitance assembly 100 generates a capacitance change according to whether the atomization medium is inserted. The capacitance processing assembly 200 analyzes the type of the atomization medium according to the capacitance of the to-be-measured capacitance assembly 100, and determines the heating control mode of the aerosol generating device according to the type of the atomization medium. The heating control mode is automatically adjusted according to the type of the atomization medium, without the need for the user to operate the keys, thereby improving the convenience of use.

[0066] In an embodiment, the to-be-measured capacitance assembly 100 includes a to-be-measured capacitance connected to the capacitance processing assembly 200. The to-be-measured capacitance can be designed as a ring-shaped capacitance. Specifically, the to-be-measured capacitance can be arranged at the cavity of the aerosol generating device into which the atomization medium is inserted. The capacitance processing assembly 200 detects the actual capacitance value of the to-be-measured capacitance assembly 100 and compares it with the corresponding preset initial capacitance value, to determine whether the capacitance value of each to-be-measured capacitance changes, thereby obtaining the current position of the atomization medium and whether the atomization medium is in the inserted state or the pulled-out state. In addition, the capacitance processing assembly 200 can also directly determine the type of the atomization medium according to the actual capacitance value range of the to-be-measured capacitance.

[0067] The specific structure of the to-be-tested capacitor is not unique. The material of the base body of the to-be-tested capacitor can be divided into two types: conductive and non-conductive. According to the material of the base body, the design form of the capacitor plate will also be different. In an embodiment, the to-be-tested capacitor includes a capacitor plate and a base body of non-conductive material, and the capacitor plate is arranged on the base body. The number of capacitor plates is two or more. In the insertion direction of the atomized medium (for example, when inserted vertically), the two or more capacitor plates are located at different horizontal heights. Among them, the capacitor plate is a closed loop plate or a non-closed loop plate. Specifically, the base body can be designed as a hollow cylindrical base body for accommodating the atomized medium. The capacitor plates are arranged in a loop on the base body, and can be arranged on the outside or inside of the base body and longitudinally distributed along the base body. In an embodiment, the number of capacitor plates is two, and the capacitor plates are arranged on the inner wall or outer wall of the cylindrical base body. Specifically, the cylindrical base body can be designed as an open-ended cylindrical base body, and then the capacitor plates are arranged on the inner wall or outer wall of the cylindrical base body.

[0068] Among them, the capacitor plate adopts a metal plate, which can be a flexible or electroplated plate. The loop-shaped capacitor plate can have a circular, rectangular, arcuate, triangular, spiral or composite shape. In addition, as shown in Figure 2 , the two side edges of the capacitor plate can be linear, nonlinear, planar or non-planar one or more segments.

[0069] As shown in Figure 3 and Figure 4 , the capacitor plates A and B can be arranged on the non-conductive base body 10 by bonding, coating or electroplating. The capacitor plates A and B form a pair of equivalent capacitors. The structure of each capacitor plate can be closed or non-closed, and can also be any combination of closed loop plates and non-closed loop plates.

[0070] Further, the capacitor plates form a loop 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 a loop plate group; when the number of capacitor plates is greater than or equal to three, the loop plate group can be formed in a one-to-many or many-to-many manner. Specifically, there can be multiple loop plate groups on the base body 10. As shown in Figure 5 , the capacitor plates A and B form a group of electrodes, the capacitor plates A and C form a group of electrodes, and the capacitor plates A and D form a group of electrodes; or many-to-many, as shown in Figure 6 , the capacitor plates A and C form a group of electrodes, and the capacitor plates B and D form a group of electrodes.

[0071] In addition, in one embodiment, a capacitor plate can also be arranged at the bottom of the base 10 as a bottom plate, which forms an equivalent capacitor with other corresponding capacitor plates. The shape of the bottom plate is not unique and can be rectangular, circular, triangular, arcuate, spiral, or a combination of these shapes. As shown in Figure 7 , a bottom plate E is arranged at the bottom of the base 10, which forms one or more equivalent capacitors with the ring-shaped capacitor plates. For example, as shown in Figure 7 , the capacitor plate A and the bottom plate E form an equivalent capacitor; or, as shown in Figure 8 , the capacitor plate A and the bottom plate E form an equivalent capacitor, the capacitor plate B and the bottom plate E form an equivalent capacitor, the capacitor plate C and the bottom plate E form an equivalent capacitor, and the capacitor plate D and the bottom plate E form an equivalent capacitor.

[0072] In one embodiment, the number of capacitor plates is two, one end of the base 10 is closed to form a bottom wall, and one of the capacitor plates is arranged at the bottom wall of the base 10. Specifically, two capacitor plates are arranged longitudinally inside the base 10, one of which is located at the bottom wall of the base 10 as a bottom plate, and the other is located at the side wall of the base 10. The combination of the two capacitor plates can detect whether the atomized medium is inserted, and the structure is simple.

[0073] In addition, the to-be-measured capacitor can also include a heating element arranged in the base 10. The heating element can be specifically obtained by printing a resistance heating line on the base 10, which is used to heat the atomized medium.

[0074] In one embodiment, as shown in Figure 9 , the capacitor plate includes a ring portion and an extension portion arranged at the ring portion, the number of capacitor plates is two, and the extension portions of the two capacitor plates are arranged opposite to each other. Specifically, both of the two capacitor plates A and B are designed as a structure combining a ring portion and an extension portion, the extension portion of the capacitor plate is arranged at the ring portion and perpendicular to the plane where the ring 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 atomized medium can also be identified.

[0075] In another embodiment, as shown in Figure 10 , the to-be-measured capacitor includes a base 10 made of a conductive material, the base 10 is divided into two or more capacitor plates, and can be specifically divided into three capacitor plates. Among them, the capacitor plates form a ring-shaped plate group in a one-to-many or many-to-many manner. Specifically, when the base 10 is made of a conductive material, the base 10 serves as both a heating body and a capacitor plate. The base 10 is divided into multiple ring-shaped capacitor plates, as shown in Figure 10 and Figure 11As shown, the divided substrate 10 forms a pair of equivalent capacitors with the capacitor plate A and the capacitor plate B; each capacitor plate is a ring-shaped capacitor plate, which can be closed or non-closed, or any combination of closed and non-closed ring-shaped plates. The capacitor plate A and the capacitor plate B are made of metal, which can receive the atomized medium and generate heat through an external alternating magnetic field, thereby heating the atomized medium. In addition, the measured capacitor further includes an insulating member arranged between the capacitor plates. For example, an insulating member 20 is arranged between the capacitor plate A and the capacitor plate B, and the insulating member 20 can be made of ceramic. In this embodiment, the capacitor plate and the insulating member 20 are hollow, which are used to jointly accommodate the atomized medium.

[0076] Further, the capacitor plates divided from the substrate 10 form multiple groups of ring-shaped plates, which can be one-to-many in form, such as Figure 12 As shown, the capacitor plate A and the capacitor plate B form a group of electrodes, the capacitor plate A and the capacitor plate C form a group of electrodes, and the capacitor plate A and the capacitor plate D form a group of electrodes; or multiple-to-multiple, such as Figure 13 As shown, the capacitor plate A and the capacitor plate C form a group of electrodes, and the capacitor plate B and the capacitor plate D form a group of electrodes.

[0077] Correspondingly, in one embodiment, one of the capacitor plates divided from the substrate 10 can also be used as a bottom plate of the substrate 10, and the bottom plate forms equivalent capacitors with other corresponding capacitor plates. The shape of the bottom plate can also be rectangular, circular, triangular, arcuate, spiral, or a combination of these shapes. As shown, Figure 14 As shown, the substrate 10 has a bottom plate E, which forms one or more groups of equivalent capacitors with the ring-shaped capacitor plates. For example, as shown, Figure 14 As shown, the capacitor plate A and the bottom plate E form a group of equivalent capacitors; or, as shown, Figure 15 As shown, the capacitor plate A and the bottom plate E form a group of equivalent capacitors, the capacitor plate B and the bottom plate E form a group of equivalent capacitors, the capacitor plate C and the bottom plate E form a group of equivalent capacitors, and the capacitor plate D and the bottom plate E form a group of equivalent capacitors.

[0078] As shown, Figure 16 As shown, the atomized medium X is inserted into the substrate, and the atomized medium X is equivalent to one of the plates of the capacitor. The capacitor plate A and the atomized medium X form a capacitor ①, and the capacitor plate B and the atomized medium X form a capacitor ②. The equivalent capacitor diagram is shown as follows. Figure 17 The formula of the capacitor theory is as follows:

[0079]

[0080] Wherein, 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. Because the conductivity of the atomized medium X is much smaller than that of the capacitor plate A and the capacitor plate B, when the atomized medium X is inserted between the capacitor plate A and the capacitor plate B, it is equivalent to changing the dielectric constant ε of the substance between the capacitor plate A and the capacitor plate B, thereby causing the capacitance between the capacitor plate A and the capacitor plate B to change. According to whether the capacitance between the capacitor plate A and the capacitor plate B changes, it can be identified whether the atomized medium X is inserted between the capacitor plate A and the capacitor plate B. The atomized medium X can be a cigarette, a solid drug or other solid substances. In addition, the atomized medium X can also be a liquid substance contained in a solid container.

[0081] Further, in the above capacitance theoretical formula, the plate area S and the plate distance d in the atomizer are fixed and unchangeable, and the dielectric constants of different atomized media are different, so the capacitance values of the to-be-measured capacitances are also different. By collecting the capacitance values and setting the capacitance value ranges of different substances, different atomized media can be identified. For example, the following formula

[0082]

[0083]

[0084] It is known that ε1>ε2, and thus C1>C2; if it is known that ε1<ε2, then C1<C2.

[0085] By setting multiple ring-type capacitor plates, for example, 3 or 4 ring-type capacitor plates, when the atomized medium reaches the position of a certain ring-type capacitor plate, the capacitance of the corresponding position ring-type capacitor plate can be measured to change, and thus the position of the atomized medium can be determined. According to this characteristic, the insertion action and position of the atomized medium can be obtained, and thus heating can be started, and the pulling-out action and position of the atomized medium can be obtained, and thus heating can be stopped. For example, as shown in the following figure, Figure 18 The capacitor plate A and the capacitor plate B form a group of capacitors, the capacitor plate A and the capacitor plate C form a group of capacitors, and the capacitor plate A and the capacitor plate D form a group of capacitors; when the atomized medium is inserted at the B position of Figure 18 -①, the capacitance of the capacitor plate A and the capacitor plate B will change; when the atomized medium is inserted at the C position of Figure 18 -②, the capacitance of the capacitor plate A and the capacitor plate C will change; and when the atomized medium is inserted at the D position of Figure 18 -③, the capacitance of the capacitor plate A and the capacitor plate D will change. According to this characteristic, the position information of the insertion of the atomized medium can be obtained.

[0086] Depending on the combination method of the capacitor under test (UUT) assembly 100, the UUT assembly 100 can be divided into two main categories: independent test assemblies and composite test assemblies. Composite test assemblies can be further divided into series type and parallel type. For example, Figure 19 As shown, the independent test assembly only tests the capacitor body under test, where Cx represents the capacitor plates. For the series type in the composite test assembly, as shown... Figure 20 As shown, capacitors C1 and C2 are external test capacitors connected in series with capacitor plate Cx. Specifically, capacitors C1 and C2 are capacitors within the capacitance acquisition component 220.

[0088] Taking the capacitive acquisition component 220 as an example, the capacitive scanning principle of the touch chip 222 is divided into mutual capacitive scanning and self-capacitive scanning. Among them, the self-capacitive scanning is a scanning mode of self-generating and self-receiving, and the capacitance measured by the touch chip 222 is the capacitance of the electrode relative to the ground. For mutual capacitive scanning, the touch chip 222 measures the capacitance between two electrodes. According to the capacitive scanning mode of different touch chips, the connection between the touch chip 222 and the to-be-measured capacitive component 100 is divided into the following two modes: as shown in Figure 24 for the self-capacitive scanning mode, one of the plates of the to-be-measured capacitance in the to-be-measured capacitive component 100 is connected to the ground, and the other plate is connected to the signal acquisition input end of the touch chip 222. As shown in Figure 25 for the mutual capacitive scanning mode, one of the plates of the to-be-measured capacitance in the to-be-measured capacitive component 100 is connected to the signal output end of the touch chip 222, and the other plate is connected to the signal acquisition input end of the touch chip 222.

[0089] The initial capacitance value of the to-be-measured capacitive component 100 is periodically acquired and updated by the touch chip 222, and the initial capacitance value is taken as the threshold value of the change of the capacitance. When the atomizing medium is inserted and pulled out, the touch chip will acquire the capacitance value change of each group of ring-shaped plates. The position of the atomizing medium and whether it is in the inserted state or the pulled-out state can be analyzed by the main control unit 240 according to the capacitance value detected by the touch chip 222.

[0090] Further, the main control unit 240 can include a control chip and discrete devices, the control chip is responsible for collecting data information of the touch chip 222, and making control actions according to the data information of the touch chip 222. The discrete devices include power supply chip, resistance, capacitance, inductance, crystal oscillator, memory, logic gate circuit and the like supporting the work of the control chip. When the atomizing medium is inserted, the touch chip 222 can recognize the gradually inserted state according to the capacitance change of the ring-shaped capacitive plate at a specific position, and the main control unit 240 can realize the preheating. When the atomizing medium is inserted, the touch chip 222 can recognize the completely inserted state according to the capacitance change of the ring-shaped capacitive plate at a specific position, and the main control unit 240 can completely open the heating. Further, by setting different capacitance value ranges of different solid atomizing media, the touch chip 222 can recognize the solid atomizing medium according to the acquired capacitance value, and then the main control unit 240 can adopt different heating control modes, for example, adjust the heating and temperature control mode corresponding to the recognized solid atomizing medium when the heating is completely opened. In addition, different capacitance value ranges of different liquid atomizing media can also be set, the touch chip 222 can recognize the liquid atomizing medium according to the acquired capacitance value, and then the main control unit 240 can adopt different heating and temperature control modes, for example, adjust the heating and temperature control mode corresponding to the recognized liquid atomizing medium when the heating is completely opened.

[0091] When the atomization medium is pulled out, the touch chip 222 can identify the gradually pulled-out state according to the change of the capacitance of the ring-shaped capacitance plate at a specific position, and the master control unit 240 can realize early termination of heating or reduction of heating temperature. When the atomization medium is pulled out, the touch chip 222 can identify the completely pulled-out state according to the change of the capacitance of the ring-shaped capacitance plate at a specific position, and the master control unit 240 completely turns off the heating.
