Embodiments for Carrying Out the Invention

[0024] Hereinafter, the present application will be described in more detail with reference to the accompanying drawings and embodiments so that the object, technical means, and advantages of the present application can be more clearly understood. It should be understood that the specific embodiments described in this specification are merely for explaining the present application and are not intended to limit the present application.

[0025] Unless otherwise defined, all technical terms and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in this specification are merely for explaining specific embodiments and are not intended to limit the present application.

[0026] In the following embodiments, the term "connection" should be understood as "electrical connection", "communicable connection", etc. when there is transmission of electrical signals and data between the connected circuits, modules, units, etc.

[0027] The activation of the heating operation by the existing aerosol generator is usually realized by a button, which is inconvenient to use. In view of this situation, the present application provides an induction control device for an aerosol generator including a capacitor component to be measured and a capacitance processing component. Among them, one capacitor plate of the capacitor component to be measured is installed on a heating element for inserting an atomizing medium, and the capacitor component to be measured generates a change in capacitance according to the presence or absence of the insertion of the atomizing medium. The capacitance processing component analyzes the state of the atomizing medium based on the capacitance of the capacitor component to be measured, and controls the heating by the aerosol generator according to the state of the atomizing medium, so as to realize an intelligent determination about the insertion of the atomizing medium, achieve the purpose of intelligent start of heating of the atomizing medium, realize an intelligent determination about the extraction of the atomizing medium, achieve the purpose of intelligent end of heating of the atomizing medium, that is, it ends immediately after being extracted. In addition, the induction control device can avoid misheating in the aerosol generator without the atomizing medium and prevent dry burning in the case without the atomizing medium, so it has a certain degree of intelligent safety. In one embodiment, the atomizing medium may be a solid medium that generates an aerosol when heated. The atomizing medium may include a tobacco material, or may be a tobacco material further added with an aromatic component. The atomizing medium contains volatile tobacco flavor compounds released from the substrate when heated. In other embodiments, the atomizing medium may be a liquid medium that atomizes after heating to form an aerosol.

[0028] In one embodiment, as shown in FIG. 1, the present application provides an induction control device for an aerosol generating device including a capacitor component 100 to be measured and a capacitance processing component 200. One capacitor plate of the capacitor component 100 to be measured is installed on a heating element for inserting into an atomizing medium, and the capacitance processing component 200 is connected to the capacitor component 100 to be measured. The capacitor component 100 to be measured generates a change in capacitance depending on the presence or absence of the insertion of the atomizing medium. The capacitance processing component 200 analyzes the state of the atomizing medium based on the capacitance of the capacitor component 100 to be measured, and controls the heating by the aerosol generating device according to the state of the atomizing medium.

[0029] Specifically, the capacitor component 100 to be measured may be installed in a cavity for inserting an atomizing medium in the aerosol generating device. When the user inserts or removes the atomizing medium with respect to the aerosol generating device, the capacitor component 100 to be measured can generate a change in capacitance according to the actual insertion position of the atomizing medium. The capacitance processing component 200 stores in advance the initial capacitance value of the capacitor component 100 to be measured as a comparison threshold value. After detecting the actual capacitance of the capacitor component 100 to be measured, it compares with the comparison threshold value to determine whether the atomizing medium is in the inserted state or the removed state, and further controls the heating by the aerosol generating device according to the state of the atomizing medium. For example, when the insertion of the atomizing medium is detected, the capacitance processing component 200 controls the power supply module to supply power and start heating. However, when the removal of the atomizing medium is detected, it is also possible to control to cut off the power supply module and end the heating.

[0030] Among them, the number of capacitor plates of the capacitor component 100 to be measured is not unique, and may be two, or may be three or more. The configurations of the capacitor plates may all be the same as each other, or some may be the same or all may be different. Specifically, when the capacitor component 100 to be measured includes two capacitor plates, it is possible to determine whether the atomizing medium is in the inserted state or the extracted state based on the capacitance of the capacitor component 100 to be measured.

[0031] It can be understood that the form in which the capacitance processing component 200 controls the heating by the aerosol generator according to the state of the atomizing medium is not unique. In one embodiment, when the capacitance processing component 200 can identify the insertion of the atomizing medium based on the capacitance of the capacitor component 100 to be measured, it controls the aerosol generator to start heating, while when it can identify the extraction of the atomizing medium based on the capacitance of the capacitor component 100 to be measured, it controls the aerosol generator to end heating. By detecting the capacitance of the capacitor component 100 to be measured, the insertion and extraction of the atomizing medium are identified, and automatic control of heating based on the state of the atomizing medium is realized.

[0032] In one embodiment, when the difference between the capacitance of the capacitor component 100 to be measured and a predetermined capacitance is greater than a first predetermined threshold, the insertion of the atomizing medium is identified. Among them, the initial capacitance value of the capacitor component 100 to be measured 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. When the difference between the actual capacitance of the capacitor component 100 to be measured and the predetermined capacitance C0 is greater than the first predetermined threshold Cth1, it is considered that the insertion of the atomizing medium is identified, and the capacitance processing component 200 automatically controls the aerosol generator to start heating.

[0033] Furthermore, in one embodiment, when the difference between the capacitance of the capacitor component 100 to be measured and the capacitance corresponding when the insertion of the atomizing medium is identified is greater than a second predetermined threshold, the capacitance processing component 200 identifies it as the extraction of the atomizing medium. Specifically, the value of the second predetermined threshold Cth2 is not unique either and can be set according to the actual situation. The capacitance processing component 200 stores the capacitance C1 of the capacitor component 100 to be measured when the insertion of the atomizing medium is identified, and continuously detects the actual capacitance of the capacitor component 100 to be measured. When the capacitance of the capacitor component 100 to be measured 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 extraction of the atomizing medium is identified, and the capacitance processing component 200 controls the aerosol generator to end the heating.

[0034] The specific configuration of the capacitance processing component 200 is not unique either. In one embodiment, the capacitance processing component 200 includes a capacitance collection component 220 and a main control unit 240. The capacitance processing component 200 is connected to the capacitor component 100 to be measured and the main control unit 240. Among them, the output end of the capacitor component 100 to be measured is connected to the input end of the capacitance collection component 220, and the input end and output end of the capacitance collection component 220 and the main control unit 240 are connected. Specifically, the capacitance collection component 220 can adopt a touch chip, a 555 timer, an RC circuit, or other circuits capable of collecting capacitance. After the capacitance collection 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 collection component 220 to achieve the purpose of controlling an external device. Further, in one embodiment, the capacitance collection component 220 may include a touch chip and a detection circuit. The touch chip is connected to the capacitor component 100 to be measured through the detection circuit. Among them, the detection circuit may specifically include a capacitor for being connected in series or in parallel with the capacitor plate in the capacitor component 100 to be measured.

[0035] In the induction control device of the aerosol generating device described above, one capacitor plate of the capacitor component 100 to be measured is installed on a heating element for inserting an atomizing medium. The capacitor component 100 to be measured generates a change in capacitance according to the presence or absence of the insertion of the atomizing medium. The capacitance processing component 200 analyzes the state of the atomizing medium based on the capacitance of the capacitor component to be measured, and controls the heating by the aerosol generating device according to the state of the atomizing medium, thereby automatically controlling the heating in consideration of the state of the atomizing medium, and achieving the technical effect that the user does not need to activate the heating by the aerosol generating device with a button, and the usability is improved.

[0036] It can be understood that the specific configuration of the capacitor component 100 to be measured is not unique. In one embodiment, as shown in FIG. 2, the capacitor component 100 to be measured includes a substrate (not shown), a first capacitor electrode plate 110, and a second capacitor electrode plate 120. The first capacitor electrode plate 110 and the second capacitor electrode plate 120 are installed on the substrate so as to be arranged along the insertion direction of the atomizing medium. The second capacitor electrode plate 120 is installed on a heating element for insertion into the atomizing medium. Specifically, in some embodiments, a part of the heating element can be used as the second capacitor electrode plate 120. For example, the part of the top end of the heating element that penetrates into the atomizing medium can be used as the second capacitor electrode plate 120, or the part of the heating element that does not penetrate into the atomizing medium can be used as the second capacitor electrode plate 120. In some other embodiments, the entire heating element can be used as the second capacitor electrode plate 120.

[0037] Among them, the substrate is made of a non-conductive material. In the insertion direction of the atomizing medium (for example, when inserted vertically), the first capacitor electrode plate 110 and the second capacitor electrode plate 120 are located at different heights. The configurations of the first capacitor electrode plate 110 and the second capacitor electrode plate 120 may be the same or different. The first capacitor electrode plate 110 and the second capacitor electrode plate 120 may adopt a metal electrode plate or a mixed structure of non-metal and metal. Furthermore, the first capacitor electrode plate 110 and the second capacitor electrode plate 120 may be installed by bonding, coating, or electroplating on the non-conductive substrate. The first capacitor electrode plate 110 and the second capacitor electrode plate 120 respectively become the two electrode plates of the capacitor to be measured.

[0038] Specifically, the base may be designed as a hollow cylindrical base for housing the atomizing medium. The first capacitor electrode plate 110 and the second capacitor electrode plate 120 may specifically be located inside the base and arranged along the longitudinal direction of the base. For example, the cylindrical base may be designed with both ends open, and the capacitor electrode plates may be installed on the cylindrical outer wall surface or the inner wall surface of the base. The relative positional relationship between the first capacitor electrode plate 110 and the second capacitor electrode plate 120 is not unique either. The first capacitor electrode plate 110 and the second capacitor electrode plate 120 may partially overlap or may not completely overlap in the insertion direction of the atomizing medium. In one embodiment, as shown in FIG. 2, the first capacitor electrode plate 110 and the second capacitor electrode plate 120 do not completely overlap along the insertion direction of the atomizing medium. Or, in another embodiment, as shown in FIG. 3, the first capacitor electrode plate 110 and the second capacitor electrode plate 120 partially overlap along the insertion direction of the atomizing medium.

[0039] Taking the case where the first capacitor electrode plate 110 and the second capacitor electrode plate 120 do not completely overlap in the insertion direction of the atomizing medium as an example, the state of the atomizing medium can be divided into two types as shown in FIGS. 4 and 5. As shown in FIG. 4, at least a part of the atomizing medium X is housed in the medium storage tube 300 of the aerosol generating device, and the heating element where the second capacitor electrode plate 120 is located is not inserted into the atomizing medium X. As shown in FIG. 5, at least a part of the atomizing medium X is housed in the medium storage tube 300 of the aerosol generating device, and at least a part (including the case of the whole) of the heating element where the second capacitor electrode 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 to be measured also varies, 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 electrode plate 110 and the second capacitor electrode plate 120 are not unique either. In one embodiment, as shown in FIGS. 6 and 7, the first capacitor electrode plate 110 is a closed annular electrode plate or a non-closed annular electrode plate. Among them, the first capacitor electrode plate 110 may be designed as a completely closed, partially closed or non-closed annular electrode plate. In this embodiment, the first capacitor electrode plate 110 is a metal annular electrode plate. In another embodiment, the first capacitor electrode plate 110 may include an insulating ring and a metal electrode plate installed in an insulating ring shape. Among them, the insulating ring may adopt a plastic ring.

[0041] Furthermore, the outer contour of the first capacitor electrode plate 110 may be circular, square, bow-shaped, triangular, spiral, or a composite of these shapes. However, in one embodiment, as shown in FIG. 8, both side edges of the first capacitor electrode plate 110 may be one or more segments that are linear, non-linear, planar, or non-planar.

[0042] In one embodiment, the second capacitor electrode plate 120 is a tapered capacitor electrode plate. Specifically, the second capacitor electrode plate 120 may be a composite electrode plate of a tapered shape and another structure. For example, as shown in FIG. 9, the second capacitor electrode plate 120 may be a composite of a tapered shape and a cylindrical shape. Or, as shown in FIG. 10, the second capacitor electrode plate 120 may be a composite of a tapered shape and a cuboid. It can be understood that in other embodiments, the second capacitor electrode plate 120 may also be a composite of a tapered shape and more types of structures. In this embodiment, the second capacitor electrode plate 120 is a metal capacitor electrode plate. In other embodiments, the second capacitor electrode plate 120 may include an insulator and a metal ring installed on the insulator. Among them, the insulator may specifically adopt a ceramic one.

[0043] FIG. 11 is a schematic diagram showing the atomizing medium X inserted into the substrate. When the atomizing medium X is equivalently regarded as one electrode plate of a capacitor, a capacitor (1) is formed by the capacitor electrode plate A and the atomizing medium X, and a capacitor (2) is formed by the capacitor electrode plate B and the atomizing medium X. A schematic diagram of the formed equivalent capacitor is shown in FIG. 12. The theoretical formula for capacitance is as follows.

Equation

[0044] Among them, C is the capacitance value, ε is the dielectric constant between the capacitor electrode plates, S is the area of the electrode plate, and d is the distance between the electrode plates. Since the conductivity of the atomizing medium X is much smaller than that of the capacitor electrode plate A and the capacitor electrode plate B, when the atomizing medium X is inserted between the capacitor electrode plate A and the capacitor electrode plate B, it is equivalent to changing the dielectric constant ε of the substance between the capacitor electrode plate A and the capacitor electrode plate B. Therefore, the capacitance between the capacitor electrode plate A and the capacitor electrode plate B has changed. Based on whether the capacitance between the capacitor electrode plate A and the capacitor electrode plate B has changed, it is possible to identify whether the atomizing medium X has been inserted between the capacitor electrode plate A and the capacitor electrode plate B. Among them, the atomizing medium X may be a cigarette, a solid drug, or other solid substances. In some embodiments, the atomizing medium X may be a liquid substance contained in a solid container.

[0045] Based on different combination forms of the capacitor component 100 to be measured, the capacitor component 100 to be measured can be roughly classified into two types: an independent test component and a composite test component. The composite test component can be further roughly classified into a series connection type and a parallel connection type. In one embodiment, as shown in FIG. 13, for the independent test component, only the body of the capacitor to be measured is measured, where Cx is the capacitor plate. For the series connection type of composite test component, as shown in FIG. 14, capacitors C1 and C2 are external test capacitors connected in series with the capacitor plate Cx, specifically, the capacitors in the capacitance collection component 220. There is no limit to the number of capacitors connected in series, and it may be one, two, or three or more, but specifically, it can be adjusted according to actual needs. In some embodiments, the capacitors connected in series may be finished capacitors manufactured by a capacitor manufacturer or capacitors composed of components.

[0046] Furthermore, for the parallel connection type of composite test component, as shown in FIG. 15, capacitors C1 and C2 are external test capacitors connected in parallel with the capacitor plate Cx, specifically, the capacitors in the capacitance collection component 220. There is no limit to the number of capacitors connected in parallel, and it may also be one, two, or three or more, but specifically, it can be adjusted according to actual needs. The capacitors connected in parallel may be finished capacitors manufactured by a capacitor manufacturer or capacitors composed of components.

[0047] As shown in FIGS. 16 and 17, taking the adoption of the touch chip 222 as the capacitance collection component 220 as an example, the capacitance scanning principle of the touch chip 222 can be divided into mutual capacitance scanning and self-capacitance scanning. Among them, self-capacitance scanning is a self-transmitting and receiving type of scanning method, and the capacitance measured by the touch chip 222 is the capacitance of the electrode with respect to the ground. In the case of mutual capacitance scanning, what is measured by the touch chip 222 is the capacitance between two electrodes. According to the capacitance scanning methods of different touch chips, the connection between the touch chip 222 and the capacitor component 100 to be measured can be divided into the following two forms. In the case of the self-capacitance scanning method, as shown in FIG. 16, one capacitor plate of the capacitor component 100 to be measured is connected to the ground Ground, and the other capacitor plate is connected to the signal collection input end of the touch chip 222. In the case of the mutual capacitance scanning method, as shown in FIG. 17, one capacitor plate of the capacitor component 100 to be measured is connected to the signal output end of the touch chip 222, and the other capacitor plate is connected to the signal collection input end of the touch chip 222.

[0048] By periodically collecting and updating the initial capacitance value of the capacitor component 100 to be measured by the touch chip 222, the initial capacitance value is set to a predetermined capacitance C0. When the atomization medium is inserted, the capacitance of the capacitor component 100 to be measured becomes C1. If the difference between C1 and C0 is greater than the first predetermined threshold Cth1, the insertion of the atomization medium is identified and heating starts. When the atomization medium is withdrawn, the capacitance of the capacitor component 100 to be measured becomes C2. If the difference between C1 and C2 is greater than the second predetermined threshold Cth2, the withdrawal of the atomization medium is identified 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 of the touch chip 222 and perform control operations based on the data information of the touch chip 222. The discrete devices include a power chip, resistors, capacitors, inductors, crystal oscillators, memories, logic gate circuits, etc. that assist in the operation of the control chip. When the atomization medium is inserted, the touch chip 222 identifies the insertion state based on the change in the capacitance of the capacitor component 100 to be measured, and the main control unit 240 starts heating. When the atomization medium is withdrawn, the touch chip 222 identifies the withdrawal state based on the change in the capacitance of the capacitor component 100 to be measured, and the main control unit 240 ends heating.

[0050] In one embodiment, an aerosol generating device including the above-described induction control device is further provided.

[0051] In the above aerosol generating device, one capacitor plate of the capacitor component to be measured is installed on a heating element for inserting the atomization medium, and the capacitor component to be measured generates a change in capacitance depending on the presence or absence of the insertion of the atomization medium. The capacitance processing component analyzes the state of the atomization medium based on the capacitance of the capacitor component to be measured and controls the heating by the aerosol generating device according to the state of the atomization medium, thereby realizing automatic control of heating considering the state of the atomization medium. There is no need for the user to activate the heating by the aerosol generating device with a button, and the usability is improved.

[0052] Each of the technical features of the above embodiments can be arbitrarily combined. For the sake of brevity of description, not all possible combinations of the technical features of the above embodiments have been described. However, as long as there is no contradiction in the combination of these features, it should be considered within the scope described in this specification.

[0053] The above embodiments merely show some embodiments of the present application specifically and in detail, and should not be construed as limiting the scope of the claims. Those skilled in the art should note that without departing from the spirit of the present application, many modifications and improvements can be made, and all of them are included in the protection scope of the present application. Therefore, the protection scope of the present invention shall be subject to the appended claims.
