[0049] In related technologies, aerosol generation devices can generate aerosols by heating an aerosol-generating matrix. It is understood that the key component of an aerosol generation device for generating aerosols is the heating element. The aerosol generation device not only contains and confines the aerosol-generating matrix to be heated, but also, under energized conditions, provides heat to the matrix confined within, enabling it to atomize and generate aerosols. The aerosol generation device has a confining cavity within its confining structure to accommodate the aerosol-generating matrix.

[0050] However, traditional aerosol generation equipment has a low utilization rate of the aerosol generation matrix. During heating, some of the aerosol generation matrix fails to atomize and generate aerosols, resulting in a lower total amount of aerosols generated by the aerosol generation matrix, fewer total number of pumps for the user, and a certain impact on the user experience.

[0051] To address the aforementioned issues and improve the low utilization rate of the aerosol generation matrix in aerosol generation equipment, this application provides an aerosol generation device and its heating control method. The aerosol generation device can be structurally improved, and the control method can be improved to increase the utilization rate of the aerosol generation matrix, increase the total amount of aerosols generated by the aerosol generation matrix within a certain range, increase the total number of times the aerosol generation matrix is ​​drawn, and ultimately improve the user experience.

[0052] It should be noted that the aerosol generating matrix can generate aerosols under heating conditions, and the aerosols may contain volatile compounds. The aerosol generating matrix can be, but is not limited to, materials used for medical, health, and cosmetic purposes. For example, the aerosol generating matrix can be plant-based materials, such as plant roots, stems, leaves, flowers, buds, and seeds. Those skilled in the art should understand that the structure of the aerosol generating matrix can refer to existing structures in related technologies, and the assembly structure and shape of the various components in the aerosol generating device can refer to existing structures in related technologies; further detailed descriptions are not provided in this application.

[0053] In the embodiments of this application, the aerosol generating matrix can be a solid matrix or a liquid matrix. Taking a solid matrix as an example, those skilled in the art will understand that the aerosol generating matrix can be a solid structure made of solid materials, or a cotton structure that has adsorbed a certain amount of liquid materials and is in a wetted state.

[0054] According to an embodiment of this application, an embodiment of an aerosol generating device is provided. Figure 1 This is a schematic diagram of the structure of an aerosol generating device according to an embodiment of this application, as shown below. Figure 1 As shown, the aerosol generating device 10 includes: The substrate 1 is provided with a receiving cavity 101, which is used to receive the aerosol-generated matrix 20.

[0055] The heating element 2 is disposed within the base 1 and surrounds the receiving cavity 101. The heating element includes an induction heating unit and a resistance heating unit, and the resistance value of the induction heating unit is less than the resistance value of the resistance heating unit.

[0056] The induction heating unit is configured to generate a magnetic field when energized, so that the inductor inside the aerosol generation matrix heats up under the action of the magnetic field, thereby heating the central region of the aerosol generation matrix; the resistance heating unit is configured to heat up when energized, thereby heating the outer peripheral region of the aerosol generation matrix.

[0057] Figure 2This is a schematic diagram of the structure of an aerosol generating device provided in one embodiment of this application. Figure 3 This is a schematic diagram of the structure of the heating component and leads in an aerosol generating device provided in a certain embodiment of this application.

[0058] Please see Figure 1 , Figure 2 and Figure 3 This application provides an aerosol generating device 10. The outer shell of the aerosol generating device is provided with a substrate 1 and a heating component 2 (located in the substrate 1). The substrate 1 is provided with a receiving cavity 101 for accommodating the aerosol generating matrix 20. The heating component 2 is located in the substrate 1 and is arranged around the receiving cavity 101.

[0059] In some embodiments, the substrate 1 is an insulating structure used to fix the heating component 2 and the aerosol generating matrix 20.

[0060] Please see Figure 3 and Figure 4 The heating component 2 includes an induction heating unit 21 and a resistance heating unit 22. The induction heating unit 21 is configured to generate a changing magnetic field when energized, and the resistance heating unit 22 is configured to generate heat when energized.

[0061] In some embodiments, at least a portion of the magnetic field generated by the induction heating unit is located within the containment cavity. The inductor located within the aerosol-generating matrix in the containment cavity can generate heat under the influence of the magnetic field, thereby heating the aerosol-generating matrix located within the containment cavity.

[0062] In some embodiments, the resistance heating unit can directly contact the aerosol generating matrix confined within the containment cavity and heat the aerosol generating matrix, or it can conduct the generated heat to the substrate 1 and heat the aerosol generating matrix confined within the containment cavity through the substrate.

[0063] In some embodiments, please refer to 1. Figure 2 and Figure 3 The substrate 1 may include a tubular structure that can enclose and form the aforementioned receiving cavity 101. The tubular structure also includes a first sidewall 102 and a second sidewall 103, wherein the first sidewall 102 is the inner peripheral wall of the tubular structure and the second sidewall 103 is the outer peripheral wall of the tubular structure. The aforementioned heating component 2 may be disposed on the first sidewall 102 of the substrate 1, or on the second sidewall 103 of the substrate 1, or between the first sidewall 102 and the second sidewall 103 of the substrate 1.

[0064] Of course, there is also the possibility that the induction heating unit 21 constituting the heating component 2 is located outside the second sidewall 103 of the substrate 1, and the resistance heating unit 22 is in contact with the substrate 1.

[0065] Please see Figure 2 and Figure 3 The induction heating unit 21 and the resistance heating unit 22 in the heating component 2 are both located between the first sidewall 102 and the second sidewall 103 of the base 1.

[0066] Specifically, the heating element is completely enclosed by the substrate at this time. In addition to the first and second sidewalls, the outer surface of the substrate 1 also has two end faces 104 in the longitudinal direction. No part of the heating element extends beyond either outer surface of the substrate, that is, the heating element will not be exposed from the outer peripheral surface of the substrate or from either end face 104 in the longitudinal direction.

[0067] It should be noted that no part of the heating element extends beyond any outer surface of the substrate. This can be understood as no part of the heating element extending beyond the outer surface boundary of the substrate in space. In this case, no surface of the heating element is exposed relative to the substrate.

[0068] by Figure 2 Taking the structure shown as an example, the substrate 1 is a hollow cylindrical structure. The arrow in the figure points in the direction of the length of the substrate 1, that is, the longitudinal direction of the substrate 1. The heat generated by the resistance heating unit in the heating component can be used to heat the substrate, so as to generate a matrix by heating the aerosol confined in the receiving cavity through the substrate.

[0069] In addition, this structure also helps to prevent the heating component from directly contacting the aerosol generation matrix, thereby protecting the heating component from damage caused by the aerosol generation matrix or aerosols.

[0070] In some embodiments, the aerosol generating device also includes leads connected to a heating element, which can be connected to an external circuit to enable circuit conduction.

[0071] In some embodiments, the heating element is embedded within the substrate 1 and connected to a lead 5 passing through the substrate 1 (e.g., Figure 2 Lead 5 is shown.

[0072] In this embodiment, the sensor pre-built into the aerosol generating matrix can be an iron product or any other metal product that can generate heat under changing magnetic field conditions.

[0073] Taking the example of a sensor being confined within an aerosol generating matrix, when the aerosol generating matrix is ​​inserted into a set position or set area within the receiving cavity, the sensor confined within the aerosol generating matrix is ​​located within the range of the changing magnetic field generated by the induction heating unit and can generate heat in the changing magnetic field.

[0074] Taking the sensor as an independent component that can extend into the receiving cavity as an example, after the sensor is assembled with the aerosol generating device, the sensor is located within the changing magnetic field range generated by the induction heating unit and can generate heat in the changing magnetic field. When the aerosol generating matrix is ​​inserted into the receiving cavity, the sensor can pierce the outer packaging of the aerosol generating matrix and insert itself into the aerosol generating matrix to heat the middle part of the aerosol generating matrix.

[0075] When the aerosol generating equipment only has an induction heating unit, the aerosol generating equipment heats the aerosol generating matrix only through central heating. This leads to local overheating in the center of the aerosol generating matrix due to concentrated heat, which also affects the flavor of the aerosol to some extent. At the same time, the outer periphery of the aerosol generating matrix is ​​underheated due to insufficient heat transfer.

[0076] This heating method reduces the utilization rate of the aerosol generation matrix to some extent. Some materials around the aerosol generation matrix are not completely atomized, resulting in a lower total amount of aerosols produced and fewer total number of pumps, ultimately affecting the user experience.

[0077] When a resistance heating unit with circumferential heating function is combined with an induction heating unit, the resistance heating unit can heat the aerosol generation matrix in the circumferential direction, thereby helping to further atomize the material located on the periphery of the aerosol generation matrix and improve the utilization rate of the aerosol generation matrix.

[0078] In the aerosol generation device provided in this application embodiment, the magnetic field generated by the induction heating unit can act on the inductor assembled in the receiving cavity, causing the inductor, confined within the receiving cavity, to heat up in the changing magnetic field; the resistance heating unit can directly heat the substrate. The aerosol generation device can achieve central heating and / or circumferential heating of the aerosol generation substrate located in the receiving cavity through the above structure, achieving sufficient heating and baking of the aerosol generation substrate, which helps to improve the utilization rate of the aerosol generation substrate and improve the user experience.

[0079] When the induction heating unit is energized, the aerosol-generating matrix confined within the substrate's containment cavity can be centrally heated by the inductor working in conjunction with the induction heating unit. This allows for rapid preheating of the aerosol-generating matrix, enabling rapid aerosol release within a shorter time and reducing user waiting time. When the resistance heating unit is energized, the unit generates heat and conducts it to the substrate. The substrate can then circumferentially heat the aerosol-generating matrix confined within the containment cavity, achieving sufficient heating of the outer periphery. This can, to some extent, help increase the total amount of aerosols generated and prolong the aerosol release time.

[0080] With the cooperation of induction heating unit and resistance heating unit, this aerosol generation device can achieve synergistic central heating and circumferential heating. Heat can diffuse outward from the center of the aerosol generation matrix, or penetrate inward from the outer periphery of the aerosol generation matrix, thereby achieving a large-scale coverage of the aerosol generation matrix in the axial section. This results in uniform heating of the aerosol generation matrix, thereby improving the atomization efficiency of the aerosol generation matrix and ultimately releasing more aerosols without adjusting the aerosol generation matrix itself.

[0081] From a user experience perspective, this technology can extend or increase the effective suction time and number of effective suction ports for a single aerosol generating matrix, prolonging the continuous release time of the aerosol generating matrix and making it more durable. Furthermore, uniform heating can improve the taste of the generated aerosol, making its flavor more stable.

[0082] Taking the number of suction ports as an example, this aerosol generating device helps to increase the number of suction ports for the aerosol generating matrix. For instance, a single heating method can allow the aerosol generating matrix to be suctioned 2-6 times, while the improved aerosol generating device can allow the aerosol generating matrix to be suctioned 24-32 times. Of course, the actual number of suction ports also varies depending on the user's suction habits. The above figures are only used to illustrate the effect and are not intended to limit the scope of protection of the embodiments of this application.

[0083] When both the induction heating unit and the resistance heating unit are energized simultaneously, compared to a single heating method, it helps to expand the heated area of ​​the aerosol generation matrix. This allows the aerosol generation matrix to quickly reach a suitable temperature and efficiently atomize to produce aerosols within a short time. During a single inhalation, the aerosol production is increased, resulting in a larger amount of aerosol obtained by the user in a single inhalation, providing a richer and more satisfying inhalation experience.

[0084] Please see Figure 2 One end of the lead wire 5 is located inside the substrate 1 to connect to the heating element embedded in the substrate 1, and the other end passes through the substrate 1 and extends outward from the substrate 1. The arrow in the figure points in the direction of the length of the substrate 1, that is, the longitudinal direction of the substrate 1.

[0085] Specifically, there are multiple leads. These leads can be spaced apart longitudinally or circumferentially along the substrate, as long as it is ensured that adjacent leads do not directly contact each other and cause a short circuit.

[0086] In this embodiment, the cross-section of the substrate in the longitudinal direction can be annular, rectangular, elliptical, or other similar shapes. This embodiment does not limit the cross-sectional shape of the substrate in the longitudinal direction; it is only necessary to ensure that the cavity formed by the substrate can accommodate the aerosol generation matrix and the sensor. For ease of description, the structure of the substrate and the heating component disposed within it will be described below using a cylindrical structure as an example.

[0087] Please refer to Figure 2 and Figure 3 The substrate 1 is a hollow cylindrical structure, and its longitudinal direction is the axial direction of the substrate 1. Multiple leads are spaced apart along the longitudinal direction of the substrate 1. The induction heating unit 21 and the resistance heating unit 22 constituting the heating component 2 are arranged sequentially along the longitudinal direction of the substrate 1 and are all located inside the substrate 1 and surround the receiving cavity 101.

[0088] In this embodiment, the heating element can be bonded to the substrate using an insert injection molding process. In this case, the substrate can cover the outer surface of the heating element, thus isolating it from the external environment. It is important to note that the heating element is completely enclosed by the substrate with no exposed outer surface.

[0089] The above structure can prevent oxidation of the heating element without affecting the insulation function of the substrate. At the same time, it can also prevent sulfur-containing gases and other corrosive gases in the external environment from directly contacting the heating element and causing damage to it.

[0090] In this embodiment, the substrate can be composed of a dense insulating material prepared by sintering. For example, the material used for the substrate can include a high-temperature resistant insulating material, which includes at least one of a ceramic material and a glass material, wherein the ceramic material includes at least one of silicon dioxide and zirconium oxide. The above-mentioned material can form a dense insulating structure with high strength and support properties after high-temperature sintering, effectively encapsulating and covering the heating element, and achieving insulating coverage of the heating element.

[0091] It should be noted that in some embodiments, the porosity of the matrix is ​​less than 20% (i.e., the predetermined porosity).

[0092] Porosity refers to the proportion of the total area of ​​pores (including pits, open pores, etc.) formed in the surface layer of the substrate (usually the surface layer exposed to the external environment) to the surface area of ​​the substrate. This limitation ensures a relatively dense substrate structure with good overall airtightness and liquid tightness, effectively preventing gas or liquid from penetrating through the substrate and contacting the heating element embedded within it. This provides better sealing and protection for the heating element, especially at the connection between the heating element and the lead wire, preventing corrosion. Furthermore, this structure also gives the substrate better strength and relatively better wear resistance, making aerosol generation equipment with this substrate more reliable and durable.

[0093] Please see Figure 3 The induction heating unit 21 and the resistance heating unit 22 are arranged sequentially along the axial direction of the base 1, wherein the induction heating unit 21 is located above the resistance heating unit 22.

[0094] The lead 5 includes a first lead 51, a second lead 52 and a third lead 53, wherein the first lead 51 and the second lead 52 are respectively connected to the two ends of the heating component 2 in the longitudinal direction of the substrate 1, and the third lead 53 is connected to the middle part of the heating component 2 in the longitudinal direction of the substrate 1.

[0095] Please see Figure 3 The induction heating unit 21 and the resistance heating unit 22 are integrally formed to constitute the heating component 2, and both the induction heating unit 21 and the resistance heating unit 22 are coil-shaped structures, the axis of which coincides with the axis of the base 1.

[0096] It should be noted that, due to the difference in heating principle, the above-mentioned induction heating unit includes a first coil with a first resistance, which is configured to generate a magnetic field under predetermined conditions; the resistance heating unit has a second resistance, and the first resistance is smaller than the second resistance.

[0097] Specifically, the first coil of the induction heating unit can generate a changing magnetic field when alternating current is applied. The magnitude of the current will affect the strength of the magnetic field to some extent. With a fixed voltage, the larger the first resistance, the smaller the current flowing into the first coil, and correspondingly, the strength of the generated magnetic field will also be weakened. The first resistance only needs to ensure that the generated magnetic field meets the design requirements; this embodiment does not limit the actual value range of the first resistance.

[0098] In some embodiments, the coil-like structure may be formed by spirally winding wires.

[0099] In this embodiment, the induction heating unit includes a first coil, and the resistance heating unit includes at least one of a second coil, a heating tube, and a heating element.

[0100] Taking a resistance heating unit including a second coil as an example, in this embodiment, please refer to... Figure 3 Both the first coil and the second coil extend spirally along the longitudinal direction of the base 1, and their axes coincide. The two ends of the first coil in the axial direction are connected to the first lead 51 and the third lead 53, respectively, to achieve circuit conduction when both the first lead 51 and the third lead 53 are simultaneously connected to an external circuit. The resistance heating unit 22 is composed of a second coil, the two ends of which are connected to the second lead 52 and the third lead 53, respectively, to achieve circuit conduction when both the second lead 52 and the third lead 53 are simultaneously connected to an external circuit. In this embodiment, at least one of the induction heating unit 21 and the resistance heating unit 22 can be controlled to be in a powered heating state by controlling different leads 5 to be connected to the external circuit. This control method and circuit connection structure have been disclosed in related technologies and will not be described again here.

[0101] It should be noted that, for reference Figure 3 As shown, the third lead 53 can be connected to the point of common coupling (PCC) of the induction heating unit 21 and the resistance heating unit 22 to meet circuit connection requirements. In a circuit, a common coupling refers to a physical connection point shared by two or more electrical components, where current converges or diverges. Since the induction heating unit and the resistance heating unit are integrally formed, the aforementioned common coupling is the connection point between the first coil and the second coil.

[0102] For example, the induction heating unit and the resistance heating unit can be welded together, and the common connection point is the welding point; or, when the induction heating unit and the resistance heating unit are composed of continuous wires, the point where the third lead is used to connect to the continuous wire is the common connection point.

[0103] Since the heating element is embedded in the substrate, one end of any of the first, second, and third leads connected to the heating element is also embedded in the substrate, and the other end extends through the outer wall of the substrate 1 along the radial direction of the substrate.

[0104] In other similar embodiments, besides the second coil, the resistance heating unit can also be a heating tube or a heating plate, wherein the outline of the heating tube can match the longitudinal outline of the substrate to ensure that the heating tube can be completely embedded in the substrate and wrapped by the substrate. When the resistance heating unit includes a heating plate, the heating plate can be a mesh or similar structure.

[0105] Taking a resistance heating unit including a second coil as an example, in this embodiment, both the first coil and the second coil, which are spirally wound, include multiple sequentially connected annular segments. Along the longitudinal direction of the substrate, there is a certain distance between any two adjacent annular segments in the first coil, and this distance is greater than zero. Similarly, there is a certain distance between any two adjacent annular segments in the second coil, and this distance is greater than zero.

[0106] It is important to note that any two adjacent annular segments are spaced apart in either the longitudinal or radial direction of the substrate. For example, two annular segments belonging to the first coil and the second coil respectively and adjacent in the longitudinal direction of the substrate can have a greater than zero gap in either the longitudinal or radial direction of the substrate.

[0107] Two adjacent loop segments can both belong to the first coil or the second coil, or they can belong to the first coil and the second coil respectively; this embodiment does not limit this. Furthermore, in the first coil and the second coil, the spacing between different loop segments can be equal or unequal.

[0108] Please see Figure 4 At this time, the first coil constituting the induction heating unit 21 includes a plurality of annular segments 210 spaced apart along the axial direction, wherein at least two of them have different spacing, and / or the second coil constituting the resistance heating unit 22 includes a plurality of annular segments 210 spaced apart along the axial direction, wherein at least two of them have different spacing.

[0109] In some embodiments, if the multiple spacings between different annular segments are along the longitudinal direction of the substrate, the spacing between adjacent annular segments can vary according to a preset rule.

[0110] Specifically, the preset rules include one of the following: at least some spacing increases sequentially, resulting in a distribution of annular segments that is initially dense and then sparse; at least some spacing decreases sequentially, resulting in a distribution of annular segments that is initially sparse and then dense; at least some spacing alternately increases and decreases, resulting in an alternating distribution of annular segments with varying density. In the embodiments of this application, the spacing between two adjacent annular segments can be set to increase or decrease sequentially along the longitudinal direction (i.e., the axial direction) of the substrate; or, the spacing between two adjacent annular segments can be set to be arranged along the longitudinal direction of the substrate in any pattern of initially dense and then sparse, initially sparse and then dense, or alternating between dense and sparse; or, the annular segments can be arranged irregularly, in which case the change in the spacing size between two adjacent annular segments is also irregular.

[0111] In the embodiments of this application, by adjusting the number and distribution density of the annular segments that constitute the induction heating unit and the resistance heating unit respectively, different heating effects can be achieved in the longitudinal direction of the substrate. This allows for adjusting the heating temperature of different positions in the aerosol generation matrix to be different, or adjusting the heating temperature of different positions in the aerosol generation matrix to be similar, in order to meet the designed heating effect and ultimately improve the taste and release amount of the generated aerosol, thereby improving the user experience.

[0112] The following is based on Figure 4 Taking the structure shown as an example, the spacing variation of the annular segment 210 provided in this application embodiment will be explained.

[0113] Please see Figure 4 At this point, the first and second coils are integrally formed to constitute the heating element. The heating element has a gradually decreasing density layout in the axial direction, with sparser distribution at the center and denser distribution at both ends. In the axial direction, the denser the distribution of the annular segments per unit distance, the greater their number; conversely, the sparser the distribution, the fewer their number. For induction heating units, a greater number of annular segments results in a stronger magnetic field and better heating; conversely, a smaller number of annular segments results in a weaker magnetic field and poorer heating. For resistance heating units, a greater number of annular segments generates more heat and a better heating effect, while a smaller number of annular segments generates less heat and a poorer heating effect.

[0114] Please see Figure 4 The spacings between two different ring segments are marked as d1, d2, d3, d4 and d5, respectively. Among them, the size of d2 is significantly larger than the size of d1, the size of d3 is significantly larger than the size of d2, the size of d4 is significantly smaller than the size of d3, and the size of d5 is significantly smaller than the size of d2. Furthermore, d3 is formed between the ring segment 210 that constitutes the first coil and the ring segment 210 that constitutes the second coil.

[0115] Along the axial direction of the substrate 1, the magnetic field strength of the induction heating unit near the resistance heating unit is less than that of the induction heating unit facing away from the resistance heating unit; the heating effect of the resistance heating unit near the induction heating unit is less than that of the resistance heating unit facing away from the resistance heating unit. This structure can, to some extent, improve the heat difference provided by the heating components at various positions along the longitudinal direction of the substrate, thereby enabling the aerosol generating device to achieve a basically consistent or nearly consistent heating effect at different positions along the longitudinal direction of the substrate.

[0116] Figure 5 for Figure 2 A schematic diagram of a certain cross-sectional structure. Figure 6 for Figure 5 Enlarged view of the structure of region A in the middle.

[0117] Please see Figure 5 , Figure 5 The structure of heating component 2 in the middle and Figure 2 The heating components 2 shown have the same structure, both with a gradually decreasing density layout that is sparse in the center and dense at both ends.

[0118] In the longitudinal direction perpendicular to the substrate (i.e. the radial direction of the substrate), the substrate has a first sidewall and a second sidewall disposed opposite to each other, wherein the first sidewall encloses and forms the aforementioned receiving cavity, and the second sidewall is located on the side of the first sidewall facing away from the receiving cavity, that is, the second sidewall constitutes the outer peripheral sidewall of the substrate.

[0119] Please see Figure 5 and Figure 6 The distance between the resistance heating unit 22 embedded in the substrate 1 and the first sidewall 102 is smaller than the distance between the resistance heating unit 22 and the second sidewall 103.

[0120] The heat generated by the resistance heating unit embedded in the substrate under energized conditions is first directly conducted to the substrate, and then the substrate heats the aerosol generation matrix confined within the cavity. During this process, most of the heat conducted to the substrate acts on the aerosol generation matrix through the first sidewall, while a small portion dissipates outward through the second sidewall. With the radial dimension of the substrate remaining constant, as the distance between the resistance heating unit and the first sidewall increases, the distance between the resistance heating unit and the second sidewall gradually decreases; conversely, as the distance between the resistance heating unit and the first sidewall decreases, the distance between the resistance heating unit and the second sidewall gradually increases. When the distance between the resistance heating unit and the second sidewall is too small, a relatively large amount of heat will be conducted out of the substrate through the second sidewall, thus affecting the heating efficiency of the aerosol generation matrix. Similarly, when the distance between the heating element and the second sidewall is small, more heat generated by the resistance heating unit can be transferred to the second sidewall, thereby improving the heating efficiency of the resistance heating unit.

[0121] In some embodiments, the radial dimension of the induction heating unit can be configured to be the same as the radial dimension of the resistance heating unit. (See also...) Figure 5 At this time, the distance between the induction heating unit and the first sidewall is less than the distance between the induction heating unit and the second sidewall.

[0122] Specifically, the distance between the resistance heating unit and the first sidewall is generally set to a range of 0-900 μm. For example, when the distance between the resistance heating unit and the first sidewall is zero, the resistance heating unit is exactly tangent to the first sidewall. In this case, the tangent line between the resistance heating unit and the first sidewall is not covered by the first sidewall, while the other parts of the resistance heating unit are wrapped and covered by the substrate (this can be considered as the resistance heating unit being completely covered by the substrate). Of course, considering manufacturing errors, this situation generally will not occur.

[0123] The distance between the resistance heating unit and the first sidewall can be set to any value from 0μm, 00μm, 0μm, 300μm, 400μm, 450μm, 5μm, 580μm, 640μm, 7μm, 758μm, 806μm, 863μm, and 900μm. This embodiment does not limit the actual value of the above distance; it only needs to ensure that the resistance heating unit maintains a small gap with the first sidewall.

[0124] In some embodiments, the aerosol generating device 10 further includes a temperature measuring element 4, which is in contact with the substrate 1 and is used to detect the temperature of the substrate 1. Referring to Figure 6, the temperature measuring element 4 can be embedded in the substrate 1 to detect the temperature inside the substrate 1.

[0125] Specifically, along the longitudinal direction of the base 1, the temperature measuring element 4 can be arranged at intervals relative to the middle of the resistance heating unit 22 and the annular segment 210 constituting the resistance heating unit 22.

[0126] Since the resistance heating unit 22 directly heats the base 1, the temperature measuring element 4 is placed in... Figure 4 and Figure 5 The position shown helps improve the accuracy of temperature detection of the substrate 1 and the resistance heating unit 22 by the temperature measuring element 4.

[0127] Of course, in other similar embodiments, the temperature measuring element 4 can be configured to contact the outer wall of the substrate 1 (e.g., one of the first side wall 102 and the second side wall 103, or one end face 104 of the substrate 1 in the longitudinal direction) according to design requirements, so as to realize the detection of the temperature of the substrate 1.

[0128] The resistance heating unit is used to heat the circumferential region of the aerosol generation matrix confined within the substrate's cavity. Therefore, the temperature detected by the temperature sensor can be used to measure the heating temperature of the circumferential region of the aerosol generation device. Correspondingly, the induction heating unit is used to heat the central region of the aerosol generation matrix confined within the substrate's cavity. To facilitate the measurement of the central heating power of the aerosol generation device, in some embodiments, the aerosol generation device may include a detection element connected to the induction heating unit. This detection element detects the current flowing through the induction heating unit to generate and output the power of the induction heating unit.

[0129] In other similar embodiments, the heating temperature of the resistance heating unit can be obtained without setting a temperature measuring element.

[0130] Specifically, the resistance heating unit can be made of a material with a resistance temperature coefficient greater than or equal to a preset value; that is, the resistance heating unit can be made of a self-temperature-regulating conductive material. The preset resistance temperature coefficient can be adaptively adjusted according to design needs, as long as it ensures that the material used to constitute the resistance heating unit has self-temperature-regulating characteristics. This embodiment does not limit the actual range of the preset resistance temperature coefficient.

[0131] Materials with a temperature coefficient of resistance (TCR) are those whose resistance changes systematically with temperature. These materials possess self-regulating temperature characteristics. Without a temperature sensor, the temperature of the resistance heating element can be obtained by reading its resistance value, facilitating precise temperature control.

[0132] When the resistance heating unit is energized, its resistance changes with temperature. At lower temperatures, the resistance is lower, and the current flowing through the unit is relatively larger. As the temperature gradually increases, the resistance increases, limiting the power output and thus achieving self-regulating temperature control. Furthermore, the control chip connected to the aerosol generation device can obtain the actual temperature of the resistance heating unit by reading its resistance value, thereby controlling its operating status.

[0133] The aforementioned control chip can be a circuit board or other structure disclosed in the relevant technology. Its working principle and connection method with the resistance heating unit have been disclosed in the relevant technology and will not be repeated here.

[0134] In other similar embodiments, both the induction heating unit and the resistance heating unit can be made of materials with a certain temperature coefficient of resistance. In this case, the temperature coefficient of resistance of the induction heating unit is a first coefficient, and the temperature coefficient of resistance of the resistance heating unit is a second coefficient. It should be noted that the first coefficient and the second coefficient are different.

[0135] In this embodiment, the second coefficient can be set to be much larger than the first coefficient.

[0136] Specifically, the material of the resistance heating unit can include a nickel-based alloy with a nickel content of 50%. For example, the nickel-based alloy is a nickel-iron alloy, in which the nickel content is approximately 50%, the remainder is mainly iron, and it also contains small amounts of other elements, such as carbon and silicon. Alternatively, the material of the resistance heating unit 22 can include at least one of a nickel-chromium-aluminum alloy and titanium.

[0137] Specifically, the material of the induction heating unit includes at least one of silver and copper. The material used to construct the induction heating unit has a small positive temperature coefficient of resistance, thus exhibiting good electrical conductivity, but it does not have self-regulating temperature characteristics.

[0138] Please see Figure 6 The cross section of the annular segment 210 used to form the first coil and the second coil has a first length L1 in the longitudinal direction of the base 1 and a second length L2 in the radial direction of the base 1 (i.e., the direction perpendicular to the longitudinal direction of the base 1 in the figure). The first length L1 is greater than or equal to the second length L2.

[0139] In this embodiment, the aforementioned cross-section refers to the cross-section of the conductor that encloses the first coil and the second coil, and the cross-section of the annular segment 210 is perpendicular to the helical extension direction of the annular segment 210. When the longitudinal section of the substrate 1 is rectangular or other structure, the aforementioned direction perpendicular to the longitudinal direction of the substrate 1 can refer to the wall thickness direction of the substrate 1, that is, the direction from the first sidewall 102 to the second sidewall 103 in the figure.

[0140] By setting the first length L1 of the annular segment's cross-section to be greater than or equal to the second length L2, it helps to increase the proportion of the projected area of ​​the annular segment facing the first sidewall of the substrate onto the surface area of ​​the first sidewall. Without changing the cross-sectional dimensions, taking a resistance heating unit as an example, this structure can increase the heat conduction area of ​​the resistance heating unit, especially the heat conduction area facing the first sidewall, thereby giving the resistance heating unit higher heat dissipation efficiency. Taking an induction heating unit as an example, this structure helps to reduce the spacing between two adjacent annular segments, thereby enhancing the magnetic field strength to a certain extent and improving the heating efficiency of the center heating.

[0141] Specifically, the first length of the cross-section of the annular segment can be set to be equal to the second length. In this case, the cross-sectional shape of the annular segment can include at least one of a circle, a square, a rounded rectangle, and other similar regular or irregular shapes. Alternatively, the first length of the cross-section of the annular segment can be set to be greater than the second length. In this case, the cross-sectional shape of the annular segment can include at least one of an ellipse, a rectangle, a triangle, and other similar regular or irregular shapes.

[0142] It should be noted that the shape and size of the cross-section of the annular segment used to form the first coil at different positions can be the same or different; similarly, the shape and size of the cross-section of the annular segment used to form the second coil at different positions can be the same or different, and this embodiment does not limit them.

[0143] For other similar embodiments, please refer to Figure 7 , Figure 7 for Figure 2 Another cross-sectional structural diagram.

[0144] Compared to the heating component 2 mentioned above, Figure 7 The heating component 2 also includes an induction heating unit 21 composed of a first coil and a resistance heating unit 22 composed of a second coil. The difference is that the spacing between the annular segments 210 used to form the first coil and the second coil is the same or substantially the same in the longitudinal direction of the substrate 1.

[0145] Specifically, you can set at least two spacings to be the same.

[0146] Please see Figure 7 In the figure, "d" is used to represent the spacing between two adjacent annular segments 210. Figure 7 The spacing between each pair of adjacent annular segments 210 shown is consistent, or consistent within the range allowed by the processing error, so that the heating components are evenly distributed in the axial direction and have a consistent axial density, without any difference in density, and finally form a regular columnar spiral shape.

[0147] Figure 8 This is a schematic diagram of the structure of an aerosol generating device 10 provided in another embodiment of this application. Figure 9 for Figure 8 A schematic diagram of the structure of the heating component 2 and the lead wire 5.

[0148] Please see Figure 8 and Figure 9 In some embodiments, the induction heating unit 21 and the resistance heating unit 22 may be arranged alternately.

[0149] Specifically, along the longitudinal direction of the substrate, at least some induction heating units and at least some resistance heating units are arranged alternately, with a portion of the annular segment constituting the induction heating unit located between the resistance heating units.

[0150] In this embodiment, the induction heating unit includes a first coil, and the resistance heating unit includes a second coil. That is, the first coil and the second coil are arranged alternately.

[0151] It should be noted that the staggered arrangement means that, along the longitudinal direction of the substrate, the winding area of ​​the first coil and the winding area of ​​the second coil partially overlap, and the two helical windings form a spatially staggered structure. This results in an overlapping area between the magnetic field generated by the first coil and the thermal field generated by the second coil in the longitudinal direction of the substrate. This area can be heated by both the induction heating unit and the resistance heating unit at the same time.

[0152] For example, such as Figure 9 As shown in the figure, the number of annular segments 210 constituting the induction heating unit 21 is eight, of which seven annular segments 210 are located on the outer side of the resistance heating unit 22 along the axial direction, and one annular segment 210 is located inside the resistance heating unit 22; correspondingly, the number of annular segments 210 constituting the resistance heating unit 22 is also eight, of which seven annular segments are located on the outer side of the induction heating unit 21 along the axial direction, and one annular segment 210 is located inside the induction heating unit 21. This heating method can simultaneously achieve central heating and circumferential heating at a certain position in the receiving cavity 101, thereby optimizing the overall heating performance of the heating assembly and achieving more complex and diverse heating effects.

[0153] It should be noted that this embodiment does not limit the spacing between adjacent ring segments forming the first coil, nor the spacing between adjacent ring segments forming the second coil, nor the spacing between adjacent ring segments formed between the first and second coils. This embodiment can achieve more complex and diverse heating effects by adjusting parameters such as the staggered positions of the induction heating unit and the resistance heating unit, the size of the staggered area, and the spacing between ring segments. This helps to further increase the diversity and flexibility of the heating modes of the aerosol generation device, meet different heating needs, and ultimately improve the user experience to some extent.

[0154] In this embodiment, the first lead is connected to the side of the induction heating unit that is away from the resistance heating unit, the second lead is connected to the side of the resistance heating unit that is away from the induction heating unit, and the third lead is connected to the common connection node of the induction heating unit and the resistance heating unit to meet the power supply requirements.

[0155] In one possible implementation, the electrodes of each lead are ceramic-coated, and the welded electrodes are integrally injection molded into the substrate along with the connected lead ends.

[0156] Please see Figure 9 The first lead 51 and the second lead 52 are respectively connected to the two ends of the integrally formed heating component 2 in the axial direction (integral forming), and the third lead 53 is connected through the common coupling (PCC) of the induction heating unit 21 and the resistance heating unit 22.

[0157] In this embodiment, the aerosol generating device 10 further includes a connecting wire 6, which connects the induction heating unit 21 and the resistance heating unit 22. A common connection node is formed on the connecting wire 6. A third lead 53 is connected to the connecting wire 6 to connect to the common connection node.

[0158] Please see Figure 8 and Figure 9 One end of the connecting wire 6 extends into the base 1 and is connected to the end of the induction heating unit 21 facing the resistance heating unit 22. The other end of the connecting wire 6 is located outside the base 1 and is connected to the third lead 53. Alternatively, both ends of the connecting wire 6 can be arranged to extend into the base 1 and be connected to the induction heating unit 21 and the resistance heating unit 22 respectively, and the third lead 53 is connected to the part of the connecting wire 6 located outside the base 1.

[0159] It should be noted that the aforementioned connecting wire can be integrally formed with the first coil constituting the induction heating unit, or it can be welded to the first coil constituting the induction heating unit. Similarly, the connecting wire can also be integrally formed with or welded to the resistance heating unit. The third lead can be integrally formed with or welded to the connecting wire.

[0160] Figure 10 This is a schematic diagram of the structure of an aerosol generating device 10 provided in another embodiment of this application. Figure 11 for Figure 10 A schematic diagram of a certain cross-sectional structure. Figure 12 for Figure 10 Another cross-sectional structural diagram.

[0161] In some embodiments, at least a portion of the induction heating unit is disposed around at least a portion of the resistance heating unit, wherein at least a portion of the resistance heating unit is located on the side of the induction heating unit facing the receiving cavity.

[0162] Please see Figure 10 Taking the substrate 1 as a tubular structure as an example, at least a portion of the induction heating unit 21 is located on the outer side of the resistance heating unit 22 in the radial direction.

[0163] It should be noted that, in order to ensure that the substrate can completely cover and encapsulate the heating element, the radial thickness of the substrate can be adjusted to a certain extent in this embodiment.

[0164] Please see Figure 11 The induction heating unit 21 and the resistance heating unit 22 are arranged sequentially along the longitudinal direction of the base 1. Figure 11 Taking the orientation shown as an example, the induction heating unit 21 is located above the resistance heating unit 22, and the orthographic projection of the induction heating unit 21 on the axial direction of the base 1 is located on the outer periphery of the orthographic projection of the resistance heating unit 22 on the axial direction of the base 1. Alternatively, the orthographic projection of the induction heating unit 21 on the axial direction of the base 1 partially coincides with the orthographic projection of the resistance heating unit 22 on the axial direction of the base 1, and part of it is located radially outside the projection of the resistance heating unit 22.

[0165] It should be noted that the distance between the resistance heating unit and the first sidewall is always less than the distance between the resistance heating unit 22 and the second sidewall.

[0166] In this embodiment, the distance between the induction heating unit and the first sidewall can be set to be smaller than the distance between the induction heating unit and the second sidewall, or the distance between the induction heating unit and the first sidewall 102 can be set to be greater than or equal to the distance between the induction heating unit and the second sidewall.

[0167] Please see Figure 12 The induction heating units are distributed longitudinally along the substrate 1, and the resistance heating units 22 are located radially inside the induction heating units. Figure 11 In contrast, induction heating units can be arranged to completely surround resistance heating units. Induction heating units can generate a variable magnetic field with a wider vertical distribution, which helps to increase the heating range of induction heating.

[0168] It is important to note that, in order not to affect the connection between the leads and the heating element, Figure 12 The distribution positions of the second lead 52 and the third lead 53 in the middle are... Figure 11 different.

[0169] Figure 13 This is a schematic diagram of the structure of an aerosol generating device 10 provided in another embodiment of this application. Figure 14 for Figure 13 A schematic diagram of the structure of the heating component 2 and the lead wire 5.

[0170] Compared with the aerosol generating device 10 described above, the heating component 2 in this embodiment includes an independent induction heating unit 21 and a resistance heating unit 22. Correspondingly, the lead wire 5 also includes a first power supply lead wire group 510 and a second power supply lead wire group 520.

[0171] Please see Figure 13 and Figure 14 The first power supply lead group 510 is connected to the induction heating unit 21 to form an independent power supply circuit, and the second power supply lead group 520 is connected to the resistance heating unit 22 to form an independent power supply circuit.

[0172] Specifically, both the first power supply lead group 510 and the second power supply lead group 520 include two wires. The two wires of the first power supply lead group 510 are used to connect to the induction heating unit 21 and form an independent power supply circuit for supplying power to the induction heating unit 21. The two wires of the second power supply lead group 520 are used to connect to the resistance heating unit 22 and form an independent power supply circuit for supplying power to the resistance heating unit 22.

[0173] It should be noted that both the first and second coils mentioned above are spirally wound wires. In other similar embodiments, the resistance heating unit can also be configured with other structures. For example, it can be a metal trace similar to a metal wire, which is prepared by processing a metal tube through patterning processes such as laser engraving or etching. This metal trace has a relatively complex pattern and can have at least one of the following complex shapes: sawtooth, straight, serpentine, zigzag, S-shaped, and mesh, as long as it does not affect the realization of its circumferential heating function.

[0174] In all the above embodiments, at least one of the induction heating unit and the resistance heating unit is a separate structure along the longitudinal direction of the substrate.

[0175] Taking the induction heating unit as an example, the induction heating unit can be an integrated structure or a multi-segment structure. In this case, the induction heating units located at different positions along the axial direction of the substrate can be started or stopped separately as needed to achieve different heating effects. Similarly, the resistance heating unit can be an integrated structure or a multi-segment structure. Multiple different resistance heating units can be spaced apart along the axial direction of the substrate to achieve separate control of the resistance heating units located at different positions along the axial direction of the substrate to achieve different heating effects.

[0176] It is understood that the heating unit provided in this application embodiment can achieve central heating of the aerosol generation matrix confined within the matrix through an induction heating unit, and circumferential heating of the aerosol generation matrix through a resistance heating unit. The two heating units work together to achieve sufficient heating and baking of the aerosol generation matrix, thereby improving the utilization rate of the aerosol generation matrix, generating more aerosols within a certain range, and extending the continuity of the aerosol generation matrix.

[0177] This application provides an example of a heating control method for an aerosol generation device. Please refer to... Figure 15 As shown, Figure 15 A schematic flowchart of a heating control method for an aerosol generating device provided in this application is shown. This is an example and not a limitation; the method can be applied to or operated in an aerosol generating device. The method includes: S1501 controls the induction heating unit to heat the central region of the aerosol generation matrix by electromagnetic induction heating.

[0178] S1502 controls the resistance heating unit to heat the outer periphery of the aerosol generation matrix by resistance heating.

[0179] In the initial heating stage, the timing of controlling the induction heating unit is earlier than the timing of starting the heating operation of the resistance heating unit.

[0180] This embodiment discloses a heating control method for an aerosol generation device, which can be applied to an aerosol generation device including an induction heating unit and a resistance heating unit. The aerosol generation device typically includes a substrate, and the substrate has a receiving cavity for accommodating the aerosol generation matrix. The induction heating unit and the resistance heating unit are arranged around the receiving cavity to achieve sufficient heating of the aerosol generation matrix in the receiving cavity and improve the utilization rate of the aerosol generation matrix.

[0181] When the induction heating unit is connected to AC power, it generates an alternating magnetic field. This alternating magnetic field can act on the pre-set inductors inside the aerosol generating matrix (such as iron-containing metal parts or other components that can generate heat in the magnetic field), so that the inductors generate heat themselves due to electromagnetic induction, thereby concentrating the heating of the central area of ​​the aerosol generating matrix (such as the area near the axial central axis of the aerosol generating matrix).

[0182] In some embodiments, the induction heating unit is typically made of materials with excellent conductivity, such as silver or copper, and has a relatively low resistance value. This allows it to efficiently generate a strong alternating magnetic field when AC power is applied, ensuring rapid preheating of the central region of the aerosol generation matrix.

[0183] Meanwhile, when the resistance heating unit is connected to the current, Joule heat is generated due to the resistance characteristics of the resistance heating unit itself. This heat can be directly conducted to the outer periphery of the aerosol generation matrix, or indirectly conducted to the outer periphery of the aerosol generation matrix through the matrix of the aerosol generation device (such as the injection-molded ceramic matrix), thereby achieving circumferential heating of the radial outer region of the aerosol generation matrix.

[0184] In some embodiments, the resistance heating unit is made of materials with high resistance and stable heating, such as nickel-based alloys and nickel-chromium-aluminum alloys. The resistance value is greater than that of the induction heating unit, which can continuously generate stable heat after being powered on, ensuring the uniformity of heating of the outer peripheral area of ​​the aerosol generation matrix.

[0185] Of particular importance is that, in the initial heating phase, the control of the induction heating unit begins earlier than the initiation of the resistance heating unit's heating operation. It should be understood that the initial heating phase is a period of time (e.g., 0.5 to 2 seconds) from the moment the aerosol generating device receives the heating command.

[0186] By prioritizing the activation of the induction heating unit, the fast response of electromagnetic induction heating allows the central area of ​​the aerosol generation matrix to reach the required atomization temperature first, shortening the user's waiting time and forming the initial aerosol channel. Meanwhile, the delayed activation of the resistance heating unit avoids localized overheating of the outer periphery of the aerosol generation matrix due to premature heating. At the same time, it works in conjunction with heat diffusion in the central area to reduce heat loss and improve the overall heating efficiency of the aerosol generation equipment.

[0187] The heating control method provided in this application fully leverages the advantages of both induction heating and resistance heating, enabling coordinated heating of the central and peripheral regions of the aerosol generation matrix. Heat diffuses outward from the center of the aerosol generation matrix while heat penetrates inward from the periphery, effectively solving the problems of uneven heating, scorching in the center, or insufficient heating of the periphery that occur with single heating methods. This achieves efficient and uniform heating of the aerosol generation matrix, improving its utilization rate, extending the number of effective suction ports for the user, and shortening the initial preheating time, thus improving the user's suction experience.

[0188] In one possible implementation, the induction heating unit is controlled to heat the central region of the aerosol generation matrix by electromagnetic induction heating, including: In response to a heating command, the induction heating unit is switched on with AC power. A magnetic field is generated when the induction heating unit is connected to AC power, and the central region of the aerosol generation matrix is ​​heated by electromagnetic induction heating, wherein an inductor is installed in the central region.

[0189] In this embodiment, controlling the induction heating unit to heat the central region of the aerosol generation matrix using electromagnetic induction heating specifically includes the following process: When the aerosol generating device receives a heating command (which can be triggered by the user through the device's operating components, such as pressing a start button or sensing a suction action), the device's control chip responds to the command, sending a power-on signal to the induction heating unit to connect it to an AC power source. For example, the AC power source can be a built-in power supply module (such as an AC output unit consisting of a battery and an inverter). The output AC parameters (such as frequency and current intensity) can be adjusted according to preset heating requirements to adapt to different types of aerosol generating matrices.

[0190] After the induction heating unit is connected to AC power, due to the principle of electromagnetic induction, the induction heating unit (such as a coil-shaped structure) generates a changing magnetic field, at least a portion of which covers the central region of the aerosol generating matrix. An inductor is pre-installed within the central region of the aerosol generating matrix; this inductor is a component (such as a metal part containing iron, nickel, etc., which can be columnar, filamentous, or sheet-like) capable of generating an induced current and heating in the changing magnetic field.

[0191] When the sensor is in the aforementioned changing magnetic field, eddy currents are generated inside the sensor due to the electromagnetic induction effect. The Joule heating of the eddy currents raises the temperature of the sensor itself, which in turn heats the central region of the aerosol generation matrix around it through heat conduction. This causes the temperature of the central region of the aerosol generation matrix to rise rapidly to the temperature range required for atomization (e.g., 200℃-350℃), thereby achieving directional heating of the central region of the aerosol generation matrix.

[0192] Through the above implementation method, the induction heating unit can utilize the characteristics of electromagnetic induction to work in conjunction with the sensor in the central area of ​​the aerosol generation matrix to achieve efficient and rapid heating of the central area, laying the foundation for subsequent collaborative work with the resistance heating unit and ensuring that the aerosol generation matrix can quickly start the atomization process in the initial stage of heating.

[0193] In one possible implementation, the control resistance heating unit heats the outer peripheral region of the aerosol generation matrix by resistance heating, including: In response to a heating command, the current is switched on to the resistance heating unit. When the resistance heating unit is connected to the current, the resistance heating unit itself generates heat to heat the outer peripheral area of ​​the aerosol generation matrix.

[0194] In this embodiment, the resistance heating unit is controlled to heat the outer peripheral region of the aerosol generation matrix by resistance heating. The specific process is as follows: When the aerosol generating device receives a heating command (which may be the same command that triggers the induction heating unit, and is triggered by the user through operating components of the aerosol generating device such as buttons or suction sensors), the control chip of the aerosol generating device responds to the command and sends an energizing signal to the resistance heating unit, controlling the resistance heating unit to connect to the power supply (which may be the built-in DC power supply of the aerosol generating device or the converted AC power supply).

[0195] It should be noted that the current parameters output by the power supply (such as current magnitude and duration) can be adjusted according to the type of aerosol generating matrix and the preset heating curve to meet the heating requirements of the outer peripheral area of ​​the aerosol generating matrix.

[0196] After the resistance heating unit is connected to the current, due to its own resistance (which is usually greater than that of the induction heating unit), Joule heat is generated when the current flows through the resistance heating unit, according to the Joule-Lenz law, causing the temperature of the resistance heating unit to rise. The structural form of the resistance heating unit can be adapted to the housing cavity of the substrate. For example, it can be coiled around the housing cavity, sheet-like and attached to the inner wall of the housing cavity, or embedded in the side wall of the substrate. The heating area can cover the outer peripheral area of ​​the aerosol generation matrix (i.e., the part of the matrix radially outer side opposite to the inner wall of the housing cavity).

[0197] In some embodiments, the heat generated by the resistance heating unit acts on the outer peripheral region of the aerosol generation matrix through two paths: first, if the resistance heating unit is in direct contact with the outer peripheral region of the aerosol generation matrix (or indirect contact through the thin wall of the matrix), the heat can be directly conducted to the outer peripheral region; second, the heat is first transferred to the matrix (such as an insulating matrix made of ceramic or glass) that encloses the resistance heating unit, and then diffuses to the inner wall of the cavity through the thermal conduction of the aerosol generation matrix, thereby heating the outer peripheral region of the aerosol generation matrix.

[0198] This process utilizes the direct heating characteristics of resistance heating to ensure a stable and uniform heat input to the outer periphery of the aerosol generation matrix, avoiding the problem of low utilization rate of the aerosol generation matrix due to insufficient heating of the outer periphery. At the same time, it works in conjunction with the induction heating unit to heat the central area of ​​the aerosol generation matrix, achieving overall heating and full utilization of the aerosol generation matrix.

[0199] Through the above implementation, the resistance heating unit can uniformly heat the outer peripheral area of ​​the aerosol generation matrix, so that the temperature of the outer peripheral area gradually rises to the temperature range required for atomization (such as 180℃-320℃), which works in synergy with the concentrated heating of the central area of ​​the aerosol generation matrix by the induction heating unit.

[0200] In one possible implementation, the method further includes: During the process of heating aerosol to generate a matrix, the heating operation is performed by an induction heating unit or a resistance heating unit per unit time, or by simultaneously using an induction heating unit and a resistance heating unit per unit time.

[0201] In this embodiment, during the process of heating aerosol to generate a matrix, the working states of the induction heating unit and the resistance heating unit are dynamically controlled. Specifically, within any unit of time, the induction heating unit can be activated to perform the heating operation, or the resistance heating unit can be activated to perform the heating operation, or both the induction heating unit and the resistance heating unit can be activated simultaneously to perform the heating operation.

[0202] The unit time refers to a continuous time period during the heating process, such as 0.1 seconds to 5 seconds. The specific duration can be adjusted according to the preset heating program of the aerosol generating equipment or the real-time heating requirements.

[0203] In some embodiments, when the induction heating unit is used per unit time, the resistance heating unit is in a de-energized state. At this time, the heat acts on the sensor in the central region of the aerosol generation matrix through the magnetic field generated by the induction heating unit, thereby achieving directional heating of the central region. This is suitable for rapidly increasing the temperature of the central region to start atomization, or for maintaining the basic temperature of the central region during the suction gap.

[0204] In some embodiments, when the resistance heating unit is used per unit time, the induction heating unit is in a de-energized state. The heat is generated by the resistance heating unit itself and conducted to the outer periphery of the matrix. This is suitable for continuously heating the outer periphery of the matrix to supplement the heat, or for separately controlling the periphery temperature when the center temperature of the matrix is ​​too high to avoid local overheating.

[0205] In some embodiments, when two heating units are used simultaneously to heat the aerosol generating matrix per unit time, both the induction heating unit and the resistance heating unit are energized, applying heat to the central and peripheral areas of the aerosol generating matrix respectively. At this time, heat can diffuse outward from the center of the aerosol generating matrix and penetrate inward from the periphery simultaneously, achieving rapid heating and uniform heating of the entire aerosol generating matrix. This is suitable for scenarios that require rapid increase in the overall temperature of the aerosol generating matrix or maintenance of stable atomization efficiency. For example, during continuous inhalation by a user, activating two heating units simultaneously can ensure that each inhalation yields sufficient aerosol.

[0206] In some embodiments, the control chip of the aerosol generation device can dynamically switch the heating modes according to a preset heating strategy or the real-time monitored state of the aerosol generation matrix (such as temperature, suction frequency, etc.). For example, in the initial stage of heating, the induction heating unit is activated separately to achieve rapid preheating, and then both units are switched to work simultaneously to ensure atomization uniformity. In the later stage of heating, the resistance heating unit can be activated separately to make full use of the remaining matrix components in the outer peripheral area of ​​the aerosol generation matrix.

[0207] Through the above embodiments, different heating modes are selected to precisely match the needs of the aerosol generation matrix at different heating stages, which not only ensures the heating efficiency of the aerosol generation matrix but also avoids energy waste, while helping to optimize the release amount and taste stability of aerosols.

[0208] In one possible implementation, the method further includes: obtaining the target heating curves corresponding to the electromagnetic induction heating method and the resistance heating method respectively, wherein the target heating curves are used to characterize the target temperature and temperature change law of the corresponding heating method at different time points; Controlling the heating of the central region of the aerosol generation matrix by the induction heating unit includes: controlling the heating process of the induction heating unit according to the target heating curve corresponding to the electromagnetic induction heating method.

[0209] Controlling the heating of the outer periphery of the aerosol generation matrix by the resistance heating unit includes: controlling the heating process of the resistance heating unit according to the target heating curve corresponding to the resistance heating method.

[0210] In this embodiment, the heating control method of the aerosol generating device further includes acquiring the target heating curves corresponding to electromagnetic induction heating and resistance heating respectively, and controlling the heating process of the two heating units based on the target heating curves.

[0211] The target heating curve is a pre-set or dynamically generated temperature control benchmark used to accurately characterize the target temperature value at different time points throughout the heating cycle of the corresponding heating method, as well as the temperature change over time (such as heating rate, holding time, cooling gradient, etc.).

[0212] As an example, and not a limitation, the target heating curve for electromagnetic induction heating can be set as follows: rapidly rising from room temperature to 280°C within 0-1 seconds (heating rate 280°C / second), maintaining 280°C for 1-5 seconds, and slowly decreasing to 250°C for 5-8 seconds; while the target heating curve for resistance heating can be set as follows: rising from room temperature to 220°C within 1-3 seconds (heating rate 110°C / second), and maintaining 220°C for 3-8 seconds.

[0213] It should be understood that the parameters of the aforementioned target heating curve can be pre-stored in the control chip of the aerosol generating device according to the type of aerosol generating matrix (such as tobacco-based, herbal-based), component characteristics and atomization requirements, or can be generated by user customization or by the aerosol generating device dynamically adjusting based on real-time monitoring data.

[0214] In some embodiments, when controlling the induction heating unit to heat the central region of the aerosol generation matrix, the control chip of the aerosol generation device calls the target heating curve corresponding to the electromagnetic induction heating method, and adjusts the working state of the induction heating unit based on this curve.

[0215] Specifically, for example, the control chip acquires the current heating time point in real time and determines the target temperature of the central region corresponding to that current heating time point based on the target heating curve. Simultaneously, it monitors the actual temperature of the central region using temperature detection components (such as thermocouples or infrared sensors associated with the sensor) and calculates the deviation between the actual temperature and the target temperature. Based on this deviation, the control chip adjusts the AC parameters input to the induction heating unit (such as current intensity and frequency): if the actual temperature is lower than the target temperature, it increases the current or adjusts the frequency to enhance the magnetic field strength and increase the sensor's heating power; if the actual temperature is higher than the target temperature, it decreases the current or reduces the frequency to weaken the magnetic field and reduce the heating power, thus ensuring that the temperature change in the central region strictly follows the target heating curve.

[0216] Similarly, when the resistance heating unit heats the outer periphery of the aerosol generation matrix, the control chip calls the target heating curve corresponding to the resistance heating method and regulates the resistance heating unit through a similar closed-loop control logic. The control chip extracts the target temperature of the outer periphery from the target heating curve based on the current time point, combines it with the actual temperature of the outer periphery obtained by temperature detection components (such as a temperature-sensing resistor or thermocouple embedded in the substrate), calculates the deviation, and adjusts the current input to the resistance heating unit: when the actual temperature is lower than the target, the current is increased to enhance the heating power; when the actual temperature is higher than the target, the current is decreased to reduce the heating power, ensuring that the temperature change of the outer periphery is consistent with the target heating curve.

[0217] By precisely controlling the target heating curve, electromagnetic induction heating and resistance heating can be adapted to the optimal atomization temperature requirements of the central and peripheral regions of the aerosol generation matrix, respectively. This avoids problems such as unstable aerosol composition or matrix waste caused by temperature fluctuations. At the same time, through the synergistic cooperation of the two curves (such as matching the rhythm of rapid heating in the center and gradual heating in the periphery), the heating uniformity and atomization efficiency are further improved, optimizing the user's inhalation experience.

[0218] In one possible implementation, the method further includes: obtaining the total energy corresponding to the electromagnetic induction heating method and the resistance heating method respectively, wherein the total energy is the sum of the energy of the corresponding heating method in the entire heating cycle, and the sum of the total energy corresponding to the electromagnetic induction heating method and the total energy corresponding to the resistance heating method is a fixed value, and the total energy corresponding to the resistance heating method is greater than the total energy corresponding to the electromagnetic induction heating method.

[0219] Controlling the heating of the central region of the aerosol generation matrix by the induction heating unit includes: controlling the heating process of the induction heating unit according to the total energy corresponding to the electromagnetic induction heating method.

[0220] Controlling the heating of the outer periphery of the aerosol generation matrix by the resistance heating unit includes: controlling the heating process of the resistance heating unit according to the total energy corresponding to the resistance heating method.

[0221] In this embodiment, the heating control method of the aerosol generating device further includes obtaining the total energy corresponding to the electromagnetic induction heating method and the resistance heating method respectively, and controlling the heating process of the two heating units based on the total energy.

[0222] The total energy corresponding to different heating methods refers to the total energy output by the corresponding heating method during the entire heating cycle (i.e., the complete period from the start of heating of the aerosol generating equipment to the stop of heating), and its magnitude is usually measured in joules.

[0223] In some embodiments, the total energy of the two heating methods has a clear numerical relationship: On the one hand, the total energy corresponding to electromagnetic induction heating and the total energy corresponding to resistance heating are added together to obtain a fixed value. This fixed value is determined in advance by factors such as the power supply capacity of the aerosol generation equipment (such as the rated capacity of the built-in battery) and the energy demand characteristics of the aerosol generation matrix. This is intended to ensure that the energy consumption of the heating process is controllable and to avoid overloading or shortening the battery life of the aerosol generation equipment due to excessive energy output.

[0224] On the other hand, the total energy required for resistance heating is greater than that required for electromagnetic induction heating. This is based on the characteristics of the working area of ​​the two heating methods. The aerosol generation matrix in the outer area usually accounts for a larger proportion, and the heat is easily dissipated into the environment, requiring more energy to ensure sufficient heating. In contrast, the central area, after rapid heating through electromagnetic induction, requires relatively less energy to maintain its temperature.

[0225] When controlling the induction heating unit to heat the central area of ​​the aerosol generation matrix, the control chip of the aerosol generation device plans and executes the heating process based on the total energy corresponding to the electromagnetic induction heating method. Specifically, the control chip calculates the average power required by the induction heating unit based on the preset total energy value and the duration of the heating cycle, and achieves power control by adjusting the AC parameters (such as current intensity and frequency) input to the induction heating unit.

[0226] For example, if the total energy is set to 100 joules and the heating cycle is 10 seconds, the average power is 10 watts. The control chip can maintain a constant power output or dynamically adjust the power at different stages (e.g., rapidly heating with 15 watts initially and maintaining the temperature with 5 watts later, so that the total energy accumulates to 100 joules) to ensure that the total energy output by the induction heating unit throughout the entire heating cycle is exactly equal to the preset total energy. Simultaneously, the control chip monitors parameters such as current and voltage to calculate the output energy in real time, compares it with the total energy, and promptly corrects the power output to avoid deviations.

[0227] Similarly, when controlling the resistance heating unit to heat the outer periphery of the aerosol generation matrix, the control chip uses the total energy corresponding to the resistance heating method as a reference for control. This total energy can be preset independently (it must meet the condition that it is greater than the total energy of electromagnetic induction heating and the sum of the two is a fixed value), or it can be obtained by subtracting the total energy of electromagnetic induction heating from a fixed value. Based on this total energy and the heating cycle, the control chip determines the average power of the resistance heating unit and controls its heating power by adjusting the magnitude of the input current.

[0228] For example, if the fixed value is 300 joules, the total energy of electromagnetic induction heating is 100 joules, and the total energy of resistance heating is 200 joules. If the heating cycle is 10 seconds, the average power is 20 watts. The control chip can ensure that the total energy output of the resistance heating unit accurately matches the preset value throughout the entire heating cycle by continuously outputting 20 watts of power or by adopting a dynamic power mode of "high first and then low". It can also perform closed-loop adjustment by monitoring energy consumption in real time.

[0229] By using the above-mentioned total energy-based control method, it is possible to ensure that the total energy output of the two heating methods is within the safe operating range of the aerosol generation equipment. Furthermore, by differentiating the energy distribution (resistance heating has a larger total energy), the heating needs of different areas of the aerosol generation matrix can be adapted. This allows the central area of ​​the aerosol generation matrix to quickly reach the atomization temperature, while the outer area can also obtain sufficient heat to achieve uniform atomization. Thus, the aerosol generation efficiency and stability are improved under the premise of energy saving.

[0230] In one possible implementation, the method further includes: In response to the user's suction action, determine the current number of suction ports of the aerosol generating device.

[0231] According to the target heating curve corresponding to the electromagnetic induction heating method, the heating process of the induction heating unit is controlled, including: determining the time interval to which the current number of suction ports belongs in the target heating curve corresponding to the electromagnetic induction heating method, and determining the target heating temperature of the current number of suction ports based on the curve parameters of the time interval. Based on the target heating curve corresponding to the resistance heating method, the heating process of the resistance heating unit is controlled, including: determining the time interval to which the current number of suction ports belongs in the target heating curve corresponding to the resistance heating method, and determining the target heating temperature of the current number of suction ports based on the curve parameters of the time interval.

[0232] In this embodiment, the heating control method of the aerosol generating device further includes responding to the user's suction action to determine the current number of suction ports of the device, and obtaining corresponding parameters from the target heating curves of the two heating methods based on the current number of suction ports, so as to achieve precise control of the heating process.

[0233] For example, aerosol generating devices monitor a user's inhalation behavior in real time using inhalation detection components (such as airflow sensors, pressure sensors, or microphone sensors). When the device detects the start of inhalation (e.g., airflow causing pressure changes as it passes through the device's air passages), the control chip of the aerosol generating device determines this as the start of an inhalation action. When the inhalation action ends (e.g., airflow is interrupted and the duration exceeds a preset threshold, for example, 1 to 3 seconds), it is recorded as a complete inhalation. The control chip accumulates and counts the complete inhalation actions to form the current number of inhalations (e.g., the 1st inhalation, the 2nd inhalation, ..., the Nth inhalation, where N is the preset maximum allowed number of inhalations for the aerosol generating device).

[0234] When controlling the induction heating unit according to the target heating curve corresponding to the electromagnetic induction heating method, the target heating curve is pre-divided into multiple continuous time intervals according to the number of suction ports. Each time interval corresponds to a specific number of suction ports and includes the temperature parameters (such as starting temperature, target temperature, heating rate, etc.) within that interval.

[0235] For example, the target heating curve can be set as follows: the time interval corresponding to the first suction is 0-5 seconds, and the target temperature rises from room temperature to 280℃; the time interval corresponding to the second suction is 5-10 seconds, and the target temperature is maintained at 280℃; the time interval corresponding to the third and subsequent suctions is 10 seconds until the heating ends, and the target temperature gradually decreases to 260℃.

[0236] After determining the current number of suction ports, the control chip matches the corresponding time interval in the electromagnetic induction heating target curve and extracts the curve parameters for that interval to determine the target heating temperature that the central region should reach under the current number of suction ports. Subsequently, the control chip adjusts the AC parameters (such as current intensity and frequency) of the induction heating unit according to the target temperature to make the actual temperature of the central region match the target value.

[0237] Similarly, when controlling the resistance heating unit according to the target heating curve corresponding to the resistance heating method, the target heating curve of the resistance heating unit is also divided into time intervals according to the number of suction ports. Each interval corresponds to a specific number of ports and sets corresponding temperature parameters, and is synchronized with the interval division of electromagnetic induction heating in time.

[0238] For example, the target curve for resistance heating can be set as follows: the time interval for the first suction is 0-5 seconds, and the target temperature rises from room temperature to 220℃; the time interval for the second suction is 5-10 seconds, and the target temperature is maintained at 220℃; the time interval for the third and subsequent suctions is 10 seconds until the heating ends, and the target temperature is maintained at 210℃.

[0239] After determining the current number of suction ports, the control chip finds the corresponding time interval in the target curve of resistance heating. Based on the curve parameters of this time interval, it determines the target heating temperature of the outer peripheral area under the current number of ports, and adjusts the input current of the resistance heating unit so that the temperature of the outer peripheral area changes based on the target value.

[0240] By linking the target heating curve with the number of puffs taken by the user, the aerosol generation device can dynamically adjust the heating strategy according to the user's actual usage rhythm: for example, the initial few puffs are heated to ensure sufficient aerosol release, and the temperature is appropriately reduced in subsequent puffs to avoid overheating of the aerosol generation matrix, so that a stable aerosol taste and concentration can be obtained in each puff, and the utilization rate of the aerosol generation matrix is ​​improved.

[0241] In one possible implementation, the method further includes: responding to the user's suction action to determine the current number of suction ports of the aerosol generating device; and determining the proportion of the current number of suction ports in the total number of suction ports.

[0242] Based on the total energy corresponding to the electromagnetic induction heating method, the heating process of the induction heating unit is controlled, including: based on a preset allocation ratio and percentage, the total energy corresponding to the electromagnetic induction heating method is allocated to the current number of suction ports to determine the energy percentage of the current number of suction ports, wherein the preset allocation ratio is an average allocation ratio or a gradient allocation ratio.

[0243] Based on the total energy corresponding to the resistance heating method, the heating process of the resistance heating unit is controlled, including: based on the preset allocation ratio and percentage, the total energy corresponding to the resistance heating method is allocated to the current number of suction ports to determine the energy percentage of the current number of suction ports.

[0244] In this embodiment, the heating control method of the aerosol generating device further includes responding to the user's suction action to determine the current number of suction ports, calculating the proportion of the current number of suction ports in the total number of suction ports, and allocating the energy proportion corresponding to the current number of suction ports to the total energy of the two heating methods based on a preset allocation ratio and the proportion, thereby controlling the heating process of the aerosol generating device.

[0245] Specifically, the device uses suction detection components (such as airflow sensors and pressure sensors) to sense the user's suction behavior in real time: when airflow is detected passing through the device's air passage or pressure changes conform to preset suction characteristics, a suction action is determined to have started; when the suction action terminates (e.g., airflow is interrupted and the duration exceeds a preset threshold, such as 1-2 seconds), it is recorded as a complete suction. The control chip accumulates the number of complete suctions to form the current number of suction ports (e.g., port 1, port 2, ... port n). The total number of suction ports is the maximum allowable number of suctions preset by the aerosol generation device (e.g., 10 ports, 12 ports, etc.), which is usually determined based on the capacity and atomization characteristics of the aerosol generation matrix.

[0246] After determining the current number of suction ports, the control chip calculates the percentage of the current suction port in the total number of suction ports, i.e., the ratio of the current suction port to the total number of suction ports (for example, if there are 10 ports in total and the current port is the 3rd, the percentage is 3 / 10 = 30%). This percentage is used to locate the current suction port in the entire heating cycle, providing a benchmark for energy distribution.

[0247] When controlling the induction heating unit according to the total energy corresponding to the electromagnetic induction heating method, the control chip allocates the total electromagnetic induction energy to the current number of suction ports based on the preset allocation ratio and the above-mentioned proportion, so as to determine the energy proportion of the current number of suction ports.

[0248] In some embodiments, the preset allocation ratio includes two forms: one is an average allocation ratio, in which the total energy is evenly distributed among the number of suction ports, with each port having an equal share of energy (e.g., 10 ports in total, each port is allocated 10% of the total energy); the other is a gradient allocation ratio, in which the total energy is distributed in a gradient according to the suction order (e.g., the first 3 ports are allocated 15% of the total energy per port, the middle 4 ports are allocated 10% per port, and the last 3 ports are allocated 5% per port). This is usually set according to the matrix atomization characteristics, with the initial few ports requiring more energy to quickly start atomization, and the energy gradually reduced thereafter to avoid overheating.

[0249] The control chip determines the percentage of electromagnetic induction energy that should be allocated to the current number of suction ports based on preset allocation rules and the proportion of the current number of ports (e.g., if the total energy is 100 joules, the current number of ports should be allocated 10%, or 10 joules). It then adjusts the AC parameters of the induction heating unit (such as current intensity and duration) to ensure that the energy output of the induction heating unit within that number of suction ports matches the allocated value. For example, if the current number of ports requires 10 joules of energy and the suction lasts for 2 seconds, the control chip adjusts the power to 5 watts (power = energy / time) to match the energy demand.

[0250] Similarly, when controlling the resistance heating unit according to the total energy corresponding to the resistance heating method, the control chip uses the same logic to allocate energy: based on the preset allocation ratio and the current port number ratio, the energy ratio of the current port number is divided from the total resistance heating energy (for example, if the total resistance energy is 200 joules, and it is evenly allocated to 10 ports, each port is allocated 20 joules). Subsequently, by adjusting the input current of the resistance heating unit (such as calculating the required current magnitude and duration based on energy demand), it is ensured that the energy output of the resistance heating unit within the current number of suction ports accurately matches the allocated value.

[0251] It should be noted that since the total energy of resistance heating is greater than the total energy of electromagnetic induction, the energy allocated per port is also correspondingly higher (as in the example above, 20 joules per resistance port is greater than 10 joules per induction port) to meet the heating requirements of the outer region of the aerosol generation matrix.

[0252] By employing an energy distribution method based on the number of inhalations, the aerosol generating device allocates total energy to each inhalation process as needed, precisely matching the energy output of the two heating methods with the user's actual inhalation rhythm. Even distribution ensures the stability of aerosol release per inhalation, while gradient distribution adapts to the atomization characteristics of the aerosol generating matrix at different inhalation stages. This ensures controllable total energy consumption while improving the consistency of taste and the utilization rate of the aerosol generating matrix for each inhalation.
