[0027] Existing aerosol generators typically activate heating operations via buttons, resulting in poor usability. In light of this situation, the present invention provides an induction control device for an aerosol generator that includes a capacitor component under test and a capacitance processing component. One capacitor plate of the capacitor component under test is placed on a heating element for insertion into the atomizing medium, and the capacitor component under test generates a change in capacitance depending on whether or not the atomizing medium is inserted. The capacitance processing component analyzes the state of the atomizing medium based on the capacitance of the capacitor component under test and controls heating by the aerosol generator according to the state of the atomizing medium. This enables intelligent determination regarding the insertion of the atomizing medium, achieving the objective of intelligently starting the heating of the atomizing medium, and also enables intelligent determination regarding the removal of the atomizing medium, achieving the objective of intelligently ending the heating of the atomizing medium, that is, ending the heating as soon as it is removed. Furthermore, the induction control device has a certain degree of intelligent safety because it can avoid erroneous heating in aerosol generators without an atomizing medium and prevent dry burning in the absence of an atomizing medium. In one embodiment, the atomizing medium may be a solid medium that generates an aerosol when heated. The atomizing medium may contain tobacco material, or may be tobacco material with further aromatic components added. The atomizing medium contains volatile tobacco-flavored compounds released from the substrate when heated. In another embodiment, the atomizing medium may be a liquid medium that atomizes after heating to form an aerosol.
[0028] In one embodiment, as shown in Figure 1, the present invention provides an induction control device for an aerosol generator including a capacitor component 100 to be measured and a capacitance processing component 200. One capacitor plate of the capacitor component 100 is installed on a heating element for insertion into an atomizing medium, and the capacitance processing component 200 is connected to the capacitor component 100. The capacitor component 100 generates a change in capacitance depending on whether or not an atomizing medium is inserted. The capacitance processing component 200 analyzes the state of the atomizing medium based on the capacitance of the capacitor component 100 and controls heating by the aerosol generator according to the state of the atomizing medium.
[0029] Specifically, the capacitor component 100 under test may be installed in the cavity for inserting the atomizing medium in the aerosol generator. When a user inserts or removes the atomizing medium from the aerosol generator, the capacitor component 100 under test can generate a change in capacitance according to the actual insertion position of the atomizing medium. The capacitance processing component 200 stores the initial capacitance value of the capacitor component 100 under test as a comparison threshold, and after detecting the actual capacitance of the capacitor component 100 under test, it compares it with the comparison threshold to determine whether the atomizing medium is in an inserted or removed state. Furthermore, it controls heating by the aerosol generator according to the state of the atomizing medium. For example, when the insertion of the atomizing medium is detected, the capacitance processing component 200 can control the power supply module to supply power and start heating, but it can also control the power supply module to shut off and end heating when the removal of the atomizing medium is detected.
[0030] In this case, the number of capacitor plates in the capacitor component 100 under test is not unique; it may be two, three, or more than three. The configurations of the capacitor plates may all be the same, some may be the same, or all may be different. Specifically, if the capacitor component 100 under test includes two capacitor plates, it is possible to determine whether the atomizing medium is in an inserted or extracted state based on the capacitance of the capacitor component 100 under test.
[0031] It is understandable that the capacitance processing component 200 does not have a unique way of controlling heating by the aerosol generator according to the state of the atomizing medium. In one embodiment, the capacitance processing component 200 controls the aerosol generator to start heating when it can identify the insertion of the atomizing medium based on the capacitance of the capacitor component 100 under test, while controlling the aerosol generator to stop heating when it can identify the removal of the atomizing medium based on the capacitance of the capacitor component 100 under test. By detecting the capacitance of the capacitor component 100 under test, the insertion and removal of the atomizing medium can be identified, and automatic control of heating based on the state of the atomizing medium is realized.
[0032] In one embodiment, the capacitance processing component 200 identifies the insertion of an atomizing medium when the difference between the capacitance of the capacitor component 100 under test and a predetermined capacitance is greater than a first predetermined threshold. The initial capacitance value of the capacitor component 100 under test may be stored as a predetermined capacitance C0, but the first predetermined threshold Cth1 is not unique and can be set according to the actual situation. If the difference between the actual capacitance of the capacitor component 100 under test and the predetermined capacitance C0 is greater than the first predetermined threshold Cth1, it is considered that the insertion of an atomizing medium has been identified, and the capacitance processing component 200 automatically controls the aerosol generator to start heating.
[0033] Furthermore, in one embodiment, the capacitance processing component 200 identifies the removal of the atomizing medium if the difference between the capacitance of the capacitor component 100 under test and the corresponding capacitance when the insertion of the atomizing medium is identified is greater than a second predetermined threshold. Specifically, the value of the second predetermined threshold Cth2 is not unique and can be set according to the actual situation. The capacitance processing component 200 stores the capacitance C1 of the capacitor component 100 under test when the insertion of the atomizing medium is identified, and continues to detect the actual capacitance of the capacitor component 100 under test. If the capacitance of the capacitor component 100 under test is detected as C2, and the difference between C2 and the capacitance C1 is greater than the second predetermined threshold Cth2, it is considered that the removal of the atomizing medium has been identified, and the capacitance processing component 200 controls the aerosol generator to terminate heating.
[0034] The specific configuration of the capacitance processing component 200 is not unique. In one embodiment, the capacitance processing component 200 includes a capacitance acquisition component 220 and a main control unit 240. The capacitance processing component 200 is connected to the capacitor component 100 under test and the main control unit 240. The output terminal of the capacitor component 100 under test is connected to the input terminal of the capacitance acquisition component 220, and the input and output terminals of the capacitance acquisition component 220 and the main control unit 240 are connected. The capacitance acquisition component 220 can specifically employ a touch chip, a 555 timer, an RC circuit, or other circuit capable of acquiring capacitance. After the capacitance acquisition component 220 converts the change in capacitance into electrical quantities such as voltage, current, resistance, frequency, and phase, the main control unit 240 processes the electrical quantity data output from the capacitance acquisition component 220 to achieve the objective of controlling an external device. Furthermore, in one embodiment, the capacitance acquisition component 220 may include a touch chip and a detection circuit. The touch chip is connected to the capacitor component 100 under test via a detection circuit, the detection circuit specifically including a capacitor that is connected in series or in parallel with the capacitor plates of the capacitor component 100 under test.
[0035] In the induction control device for the aerosol generator described above, one capacitor plate of the capacitor component 100 under test is installed on a heating element for insertion into the atomizing medium. The capacitor component 100 under test generates a change in capacitance depending on whether or not the atomizing medium is inserted. The capacitance processing component 200 analyzes the state of the atomizing medium based on the capacitance of the capacitor component under test and controls heating by the aerosol generator according to the state of the atomizing medium. This enables automatic control of heating considering the state of the atomizing medium, eliminating the need for the user to activate heating by the aerosol generator with a button, thus improving usability.
[0036] It is understandable that the specific configuration of the capacitor component 100 under test is not unique. In one embodiment, as shown in Figure 2, the capacitor component 100 under test includes a base (not shown), a first capacitor plate 110, and a second capacitor plate 120. The first capacitor plate 110 and the second capacitor plate 120 are installed on the base so as to be aligned along the insertion direction of the atomizing medium. The second capacitor plate 120 is installed on a heating element for insertion into the atomizing medium. Specifically, in some embodiments, a part of the heating element is made up of the second capacitor plate 120. For example, the portion of the top of the heating element that protrudes into the atomizing medium may be made up of the second capacitor plate 120, or the portion of the heating element that does not protrude into the atomizing medium may be made up of the second capacitor plate 120. In some other embodiments, the entire heating element may be made up of the second capacitor plate 120.
[0037] The substrate is made of a non-conductive material, and the first capacitor plate 110 and the second capacitor plate 120 are located at different heights in the direction in which the atomizing medium is inserted (for example, when inserted vertically). The configurations of the first capacitor plate 110 and the second capacitor plate 120 may be the same or different, and the first capacitor plate 110 and the second capacitor plate 120 may be made of metal or a mixed structure of non-metal and metal. Furthermore, the first capacitor plate 110 and the second capacitor plate 120 may be installed by bonding them to a non-conductive substrate and applying a coating or electroplating. The first capacitor plate 110 and the second capacitor plate 120 each become the two plates of the capacitor under test.
[0038] Specifically, the substrate may be designed as a hollow cylindrical substrate for housing the atomizing medium. The first capacitor plate 110 and the second capacitor plate 120 may be specifically located inside the substrate and arranged along the longitudinal direction of the substrate. For example, the cylindrical substrate may be designed with openings at both ends, and the capacitor plates may be installed on the cylindrical outer or inner wall surface of the substrate. The relative positional relationship between the first capacitor plate 110 and the second capacitor plate 120 is not unique; the first capacitor plate 110 and the second capacitor plate 120 may partially overlap or not completely overlap in the direction of insertion of the atomizing medium. In one embodiment, as shown in Figure 2, the first capacitor plate 110 and the second capacitor plate 120 do not completely overlap in the direction of insertion of the atomizing medium. Alternatively, in another embodiment, as shown in Figure 3, the first capacitor plate 110 and the second capacitor plate 120 partially overlap in the direction of insertion of the atomizing medium.
[0039] As an example, if the first capacitor plate 110 and the second capacitor plate 120 do not completely overlap in the insertion direction of the atomizing medium, the state of the atomizing medium can be divided into two types, as shown in Figures 4 and 5. As shown in Figure 4, at least a portion of the atomizing medium X is housed in the medium storage tube 300 of the aerosol generator, and the heating element on which the second capacitor plate 120 is located is not inserted into the atomizing medium X. As shown in Figure 5, at least a portion of the atomizing medium X is housed in the medium storage tube 300 of the aerosol generator, and at least a portion (including the entirety) of the heating element on which the second capacitor plate 120 is located is inserted into the atomizing medium X. Depending on the different states of the atomizing medium X, the capacitance of the capacitor component 100 under test will also differ, and the capacitance processing component 200 can identify the state of the atomizing medium X based on the detected actual capacitance.
[0040] The specific configuration types of the first capacitor plate 110 and the second capacitor plate 120 are not unique. In one embodiment, as shown in Figures 6 and 7, the first capacitor plate 110 is either a closed or open annular plate. The first capacitor plate 110 may be designed as a fully closed, partially closed, or open annular plate. In this embodiment, the first capacitor plate 110 is a metal annular plate. In another embodiment, the first capacitor plate 110 may include an insulating ring and a metal plate arranged in the shape of an insulating ring. The insulating ring may be a plastic ring.
[0041] Furthermore, the outer contour of the first capacitor plate 110 may be circular, square, arched, triangular, spiral, or a combination of these shapes. In one embodiment, as shown in Figure 8, the side edges of the first capacitor plate 110 may be linear, nonlinear, planar, or non-planar segments.
[0042] In one embodiment, the second capacitor plate 120 is a tapered capacitor plate. Specifically, the second capacitor plate 120 may be a composite plate of a tapered shape and another structure. For example, as shown in Figure 9, the second capacitor plate 120 may be a composite of a tapered shape and a cylindrical shape. Or, as shown in Figure 10, the second capacitor plate 120 may be a composite of a tapered shape and a rectangular parallelepiped. In other embodiments, it is understandable that the second capacitor plate 120 may be a composite of a tapered shape and a wider variety of structures. In this embodiment, the second capacitor plate 120 is a metal capacitor plate. In other embodiments, the second capacitor plate 120 may include an insulator and a metal ring placed on the insulator. The insulator may specifically be made of ceramic.
[0043] Figure 11 is a schematic diagram showing the atomizing medium X inserted into the substrate. If the atomizing medium X is equivalently considered as one plate of a capacitor, then capacitor (1) is formed by capacitor plate A and atomizing medium X, and capacitor (2) is formed by capacitor plate B and atomizing medium X. A schematic diagram of the formed equivalent capacitors is shown in Figure 12. The theoretical formula for capacitance is as follows.
number
[0044] In this system, C is the capacitance value, ε is the dielectric constant between the capacitor plates, S is the area of the plates, and d is the distance between the plates. Since the conductivity of the atomizing medium X is much smaller than that of capacitor plates A and B, when the atomizing medium X is inserted between capacitor plates A and B, it is equivalent to changing the dielectric constant ε of the material between capacitor plates A and B, and therefore the capacitance between capacitor plates A and B changes. It is possible to determine whether or not the atomizing medium X has been inserted between capacitor plates A and B based on whether or not the capacitance between capacitor plates A and B has changed. The atomizing medium X may be a cigarette, a solid medicine, or another solid substance. In some embodiments, the atomizing medium X may be a liquid substance contained in a solid container.
[0045] Based on different combinations of the capacitor component 100 under test, the capacitor component 100 under test can be broadly classified into two types: independent test components and composite test components. The composite test component can be further classified into series-connected and parallel-connected types. In one embodiment, as shown in Figure 13, the independent test component measures only the body of the capacitor under test, where Cx is the capacitor plate. The series-connected composite test component, as shown in Figure 14, is an external test capacitor in which capacitors C1 and C2 are connected in series with the capacitor plate Cx, and is specifically a capacitor within the capacitance collection component 220. There is no limit to the number of capacitors connected in series; there may be one, two, or three or more, but this can be adjusted according to the actual demand. In some embodiments, the capacitors connected in series may be finished capacitors manufactured by a capacitor manufacturer, or they may be capacitors composed of components.
[0046] Furthermore, as shown in Figure 15, the parallel-connected composite test component consists of external test capacitors, specifically capacitors within the capacitance collection component 220, where capacitors C1 and C2 are connected in parallel to the capacitor plate Cx. There is no limit to the number of capacitors connected in parallel; there may be one, two, or three or more, but this can be adjusted according to the actual demand. The capacitors connected in parallel may be finished capacitors manufactured by a capacitor manufacturer, or they may be capacitors composed of various components.
[0047] As shown in Figures 16 and 17, taking the example of using a touch chip 222 as the capacitance acquisition component 220, the capacitance scanning principle of the touch chip 222 can be divided into mutual capacitance scanning and self-capacitance scanning. Of these, self-capacitance scanning is a self-transmitting type scanning method, and the capacitance measured by the touch chip 222 is the capacitance of the electrode relative to the ground. In the case of mutual capacitance scanning, what is measured by the touch chip 222 is the capacitance between the two electrodes. Depending on the capacitance scanning method of the different touch chips, the connection between the touch chip 222 and the capacitor component 100 under test can be divided into the following two forms. In the case of the self-capacitance scanning method, as shown in Figure 16, one capacitor plate of the capacitor component 100 under test is connected to ground, and the other capacitor plate is connected to the signal acquisition input terminal of the touch chip 222. In the mutual capacitance scanning method, as shown in Figure 17, one capacitor plate of the capacitor component 100 under test is connected to the signal output terminal of the touch chip 222, and the other capacitor plate is connected to the signal acquisition input terminal of the touch chip 222.
[0048] The initial capacitance value of the capacitor component 100 under test is periodically collected and updated by the touch chip 222, thereby setting the initial capacitance value to a predetermined capacitance C0. When the atomizing medium is inserted, the capacitance of the capacitor component 100 under test becomes C1. If the difference between C1 and C0 is greater than a first predetermined threshold Cth1, the insertion of the atomizing medium is detected and heating begins. When the atomizing medium is removed, the capacitance of the capacitor component 100 under test becomes C2. If the difference between C1 and C2 is greater than a second predetermined threshold Cth2, the removal of the atomizing medium is detected and heating ends.
[0049] Furthermore, the main control unit 240 includes a control chip and discrete devices, the control chip may be configured to collect data information from the touch chip 222 and to perform control operations based on the data information from the touch chip 222. The discrete devices include a power supply chip, resistors, capacitors, inductors, crystal oscillators, memory, logic gate circuits, etc., to support the operation of the control chip. When the atomizing medium is inserted, the touch chip 222 identifies the insertion state based on the change in the capacitance of the capacitor component 100 under test, and the main control unit 240 starts heating. When the atomizing medium is removed, the touch chip 222 identifies the removal state based on the change in the capacitance of the capacitor component 100 under test, and the main control unit 240 terminates heating.
[0050] In one embodiment, an aerosol generator including the above-described induction control device is further provided.
[0051] In the above aerosol generator, one capacitor plate of the capacitor component under test is placed on a heating element for insertion into the atomizing medium, and the capacitor component under test generates a change in capacitance depending on whether or not the atomizing medium is inserted. The capacitance processing component analyzes the state of the atomizing medium based on the capacitance of the capacitor component under test and controls heating by the aerosol generator according to the state of the atomizing medium, thereby realizing automatic heating control that takes the state of the atomizing medium into consideration, eliminating the need for the user to activate heating by the aerosol generator with a button, and improving ease of use.
[0052] The technical features of the above embodiments can be combined in any way, and for the sake of brevity, not all possible combinations of the technical features of the above embodiments have been described. However, as long as these combinations of features are inconsistent, they should be considered to fall within the scope described herein.
[0053] The above embodiments merely illustrate some embodiments of the present application in a specific and detailed manner and should not be understood as limiting the scope of the claims. Those skilled in the art should note that many modifications and improvements can be made without departing from the spirit of the present application, and all of these fall within the scope of protection. Therefore, the scope of protection of the present invention shall be subject to the appended claims.
