However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details.

[0047] This application constructs an electronic atomization device for aerosol-generating products 500 (see reference). Figure 4 Heating, which includes a power module, a control module, and an aerosol generating device (see reference). Figure 1 The power module is connected to the control module, which can adjust the output of the power module to provide suitable energy for the aerosol generating device. The aerosol generating device heats and atomizes the aerosol generating product 500 to form an aerosol.

[0048] It should be further clarified that the aerosol generating product 500 is generally a separate product from the electronic atomization device; that is, the aerosol generating product 500 can be inserted into or detached from the electronic atomization device. The aerosol generating product 500 may be cylindrical in shape and contain a solid matrix such as plant-based liquids or leaves. This matrix generates aerosols when heated. This aerosol can be used in various applications, such as nebulization therapy, nebulized beauty treatments, and recreational vaping. The following explanation will focus on generating an aerosol that can be inhaled by the user.

[0049] The aerosol generating apparatus includes a heating module for heating the aerosol-generated article 500, which may include at least two different types of heating modules.

[0050] Among them, you can refer to Figure 1 , Figure 2 The heating module may include a microwave heating module 100 for implementing microwave heating, and a first heating module 200 of a different heating type than the microwave heating module 100. The microwave heating module 100 is configured to heat the aerosol-generating article 500 at least during the preheating phase. Understandably, the heating process of the aerosol generating device includes a preheating phase and a suction phase. During the preheating phase, the internal temperature of the aerosol-generating article 500 is rapidly increased to a preset temperature value, preparing it for subsequent aerosol generation. Microwave heating has the advantage of rapid heating; during the preheating phase, microwaves can be used to quickly heat the matrix of the aerosol-generating article 500, achieving rapid misting and thus improving the user experience. The first heating module 200 can be mainly used in the suction phase. (See reference...) Figure 1 The microwave heating module 100 may include a microwave generating component (not shown) and a resonant component 1. The resonant component 1 forms a resonant cavity, while the microwave generating component is responsible for generating microwaves and feeding the generated microwaves into the resonant cavity through connection with the resonant component 1, forming a microwave field that can act on the aerosol-generated product 500, thereby achieving microwave heating. It should be noted that the specific structure of the microwave generating component can be found in relevant technologies and will not be elaborated here, while the specific structure of the resonant component 1 can be found below.

[0051] Secondly, the first heating module 200 can be one of a resistance heating module 2, an electromagnetic induction heating module, or an infrared radiation heating module. Understandably, the resistance heating module 2 includes an impedance section 21 with high resistivity, which utilizes the characteristic of resistance generating heat to heat the aerosol-generating product 500. The electromagnetic induction heating module includes a magnetic field generating component and a metal component. The magnetic field generating component generates a high-frequency magnetic field, causing heat to be generated inside the metal component, thereby heating the aerosol-generating product. Infrared radiation heating includes a radiation generating component that generates infrared radiation and radiates it onto the aerosol-generating product, thereby achieving heating.

[0052] The following provides a detailed example of the resistance heating module 2 and the microwave heating module 100. In application, the control module is configured to control the aerosol generating device to operate upon receiving a trigger signal. It can be further noted that the trigger signal can be generated by a button or a sensor; the button can be a physical button or a virtual button for controlling device startup; the sensor can include a first sensor for detecting the insertion of the aerosol-generated article 500, or a second sensor for detecting the device's orientation. The aerosol generating device enters the preheating stage, during which the microwave heating module 100 operates, or the resistance heating module 2 and the microwave heating module 100 operate simultaneously. After the preheating phase, the suction phase begins. During the suction phase, when the device detects a user's suction action, one of the heating modules, either the resistance heating module 2 or the microwave heating module 100, operates independently, or both modules operate simultaneously for mixed heating to continuously produce high-quality aerosol. Furthermore, in addition to the intense heating state triggered by the suction action, the aerosol generating device also includes a heat preservation state during the suction phase. This maintains the aerosol generating device within a certain temperature range, ensuring that the user can quickly reach the atomization temperature required for the next suction, thus rapidly obtaining aerosol. The heat preservation state generally occupies most of the suction phase and can be configured to be maintained solely by the resistance heating module 2. It should be noted that the temperature curves for the preheating and suction phases can be referenced in relevant technologies and will not be elaborated upon here.

[0053] In the entire heating process of an aerosol-generating product 500, although both the resistance heating module 2 and the microwave heating module 100 participate in the heating work, the operating time of the microwave heating module 100 is shorter than that of the resistance heating module 2. Specifically, in the preheating stage, the microwave heating module 100 is configured to participate in the preheating work, mainly because microwave heating has the advantage of rapid heating, which can quickly raise the temperature in a short time, thus drastically shortening the preheating time, generally between 1 second and 5 seconds. In the suction stage, since a long period of heat preservation is required, and resistance heating has lower energy consumption and higher energy conversion efficiency, the heat preservation work can be configured to be completed by the resistance heating module 2 alone. Considering both stages, the operating time of the microwave heating module 100 is shorter than that of the resistance heating module 2. It can be further noted that microwave heating has the advantage of rapid heating, but solid-state microwaves are limited by their technical principles, resulting in higher energy consumption and lower link efficiency or energy conversion efficiency; while resistance heating has lower energy consumption and higher energy conversion efficiency, but cannot rapidly heat the medium. This application combines the advantages of both methods, employing microwave heating in the preheating stage for rapid mist generation, while using resistance heating for at least most of the suction stage to effectively reduce energy consumption. Furthermore, since the microwave generating component itself is also a significant heat source, this division of heating effectively reduces the operating time of the microwave generating component, positively impacting the reduction of the device's surface temperature.

[0054] Taking the aerosol generating article 500 as a reference, the resistance heating module 2 and the microwave heating module 100 can perform heating operations at the center of the aerosol generating article 500. Of course, to adapt to different design requirements and application scenarios, at least one of the heating modules, the resistance heating module 2 and the microwave heating module 100, can also be configured to perform heating operations in the circumferential direction on the outside of the aerosol generating article 500.

[0055] The following explanation will continue with the example of the resistance heating module 2 and the microwave heating module 100 heating the center of the aerosol-generated product 500.

[0056] The resonant component 1 can be a quarter-wavelength coaxial resonator. The resonant component 1 can be configured such that, after the aerosol generation article 500 is inserted, its resonant frequency is between 2.4 and 2.5 GHz; of course, the resonant frequency can also be configured to other frequency bands, as long as it complies with regulations.

[0057] For reference Figure 2 The resonant assembly 1 may include a cylindrical outer conductor unit 11, an inner conductor unit coaxially disposed within the outer conductor unit 11, and a medium (e.g., air) between the outer conductor unit 11 and the inner conductor unit. The outer conductor unit 11 and the inner conductor unit together form a resonant cavity.

[0058] Continue reading for more information. Figure 3 The outer conductor unit 11 has a first end 111 and a second end 112 opposite to the first end 111, wherein the first end 111 of the outer conductor unit 11 may be an open end, which can be inserted into the aerosol generating article 500.

[0059] The outer conductor unit 11 can define a cavity 113, the inner wall of which is electrically conductive. For example, the outer conductor unit 11 can be integrally made of a conductive material such as metal, which can be a conductive metal such as aluminum alloy, copper, gold, silver, or stainless steel. Of course, the outer conductor unit 11 is not limited to being integrally made of a conductive material; it can also be achieved by plating a conductive layer on the inner wall surface of a non-conductive cylinder. This conductive layer can be a gold plating layer, a silver plating layer, a copper plating layer, etc., and is not limited here.

[0060] To facilitate the explanation of the components located inside the outer conductor unit 11, the positions and connections between the components are described below with reference to the orientation or positional relationships shown in the attached figures. That is, "upper" and "top" can be understood as the side adjacent to the first end 111, and "lower" and "bottom" can be understood as the side adjacent to the second end 112.

[0061] Please combine Figure 2 , Figure 3 Referring to the diagram, the inner conductor unit includes an impedance matching structure 12 and a radiating structure 13. The bottom end of the impedance matching structure 12 is in ohmic contact with the second end 112 of the outer conductor unit 11, forming a short circuit condition; the top end of the impedance matching structure 12 extends upward and is located in the cavity 113. The bottom end of the radiating structure 13 is inserted into the impedance matching structure 12 and is in ohmic contact with it; the top end of the radiating structure 13 extends upward and is located in the cavity 113, but does not contact the outer conductor unit 11, forming an open circuit condition. The strong microwave field is mainly formed around the radiating structure 13; the aerosol generating product 500 can be inserted into the radiating structure 13 and then heated by microwaves.

[0062] The impedance matching structure 12 can be made of conductive materials such as metal, preferably aluminum alloy or copper. In other embodiments, the impedance matching structure 12 can also be formed by coating a conductive layer on the outer wall surface of a structure made of non-conductive material. This conductive layer can be a gold plating layer, a silver plating layer, a copper plating layer, etc., and is not limited thereto.

[0063] The radiating structure 13 can be a longitudinal structure, and its shape can be cylindrical, square, etc., without limitation. Secondly, the radiating structure 13 can be a solid structure or a hollow structure, which can be adjusted according to the arrangement requirements of the resistance heating module 2.

[0064] The radiating structure 13 is electrically conductive. For example, the radiating structure 13 can be made of a conductive material such as metal, preferably stainless steel, aluminum alloy, or copper. In other embodiments, the radiating structure 13 can also be formed by coating a conductive layer onto the outer wall surface of a structure made of a non-conductive material. This conductive layer can be a gold plating layer, a silver plating layer, a copper plating layer, etc., and is not limited thereto.

[0065] Please refer to Figure 2 The resonant assembly 1 may further include a receiving seat 14, which is mounted on the first end 111 of the outer conductor unit 11 to define a receiving area 141 for receiving the aerosol generating article 500. At least a majority of the receiving area 141 is located above the impedance matching structure 12, and the top end of the radiating structure 13 is configured to pass through the bottom of the receiving seat 14 and extend into the receiving area 141. Understandably, the receiving seat 14 is not a necessary component in this application, but it is used as a preferred embodiment to protect the inner wall of the cavity 113 and other components from or minimize contamination by mist. In other embodiments, the receiving area 141 may be formed directly in the cavity 113 without the need for other components to define it; for example, the aerosol generating article 500 may be directly inserted from the first end 111 of the outer conductor unit 11, in which case the space occupied by the aerosol generating article 500 in the cavity 113 can be considered as the receiving area 141.

[0066] The housing 14 can be made of a low microwave loss material, such as PTFE, PEEK, ceramics, etc., to effectively prevent the housing 14 from absorbing microwaves.

[0067] In addition, the resonant assembly 1 may also include a coaxial connector (not shown), one end of which is connected to the microwave generating assembly, and the other end of which extends into the interior of the outer conductor unit 11 and is configured to be electrically or magnetically coupled to the outer conductor unit 11 or the inner conductor unit to support microwave transmission to the resonant cavity.

[0068] Continue to refer to Figure 2 The resistance heating module 2 may include an impedance section 21 disposed at the radiating structure 13. The impedance section 21 is configured to be connected to the control module to achieve heating upon energization. When the aerosol generating article 500 is inserted into the radiating structure 13, the substrate of the aerosol generating article 500 can be heated by the heat generated by the impedance section 21.

[0069] The impedance part 21 can be disposed inside the radiation structure 13 or on the outside of the radiation structure 13. The impedance part 21 can be one of the following: filament structure, rod structure, sheet structure, plate structure, or a combination of two or more.

[0070] For example, you can refer to Figure 5In one embodiment, the impedance section 21 may be a resistance wire 211, which is wound into a longitudinal spiral shape and disposed inside the radiating structure 13. Correspondingly, the resistance heating module 2 also includes a bracket 23 and a lead wire 22. The resistance wire 211 may be wound around the outside of the bracket 23 and electrically connected to the control module through the lead wire 22.

[0071] For example, you can refer to Figure 9 In some embodiments, the impedance portion 21 may be a heating film 212, which is configured and attached to the circumferential outer surface of the radiating structure 13. The heating film 212 forms conductive paths, and current can flow through the conductive paths to generate heat by connecting to the control module. Correspondingly, the resistance heating module 2 may also include leads 22, through which the heating film 212 is electrically connected to the control module. In some embodiments, the heating film 212 may be formed on the circumferential outer surface of the radiating structure 13 by screen printing. For example, a conductive material for forming the heating film 212 is provided; the conductive material is printed on the circumferential outer surface of the radiating structure 13 according to a preset pattern by screen printing; a curing process is performed, and then the heating film 212 is formed. In other embodiments, the pre-formed heating film 212 may also be adhered to the circumferential outer surface of the radiating structure 13.

[0072] Secondly, the surface of the impedance part 21 can be insulated, for example, by coating it with an insulating coating, to prevent leakage and short circuit.

[0073] The impedance section 21 is configured not only for heating but also for temperature measurement. For example, the impedance section 21 can be made of a thermistor, such as NTC (Negative Temperature Coefficient) or PTC (Positive Temperature Coefficient) materials. Based on the property that resistance heats up when energized and that resistivity changes with temperature, the impedance section 21 achieves both heating and temperature measurement functions. Alternatively, the impedance section 21 can be made of two different metallic materials, such as nickel-chromium and nickel-iron; based on the property of resistance heating up when energized and the Seebeck effect, the impedance section 21 achieves both heating and temperature measurement functions.

[0074] The temperature measurement function can also be completed independently by a temperature measuring element 3, instead of by the impedance part 21; that is, the aerosol generating device also includes a temperature measuring element 3; the temperature measuring element 3 can be set at the radiation structure 13 to detect the temperature at the radiation structure 13.

[0075] The temperature sensing element 3 can be disposed inside or outside the radiation structure 13. The temperature sensing element 3 can be a thermistor, which measures temperature based on the characteristic that the resistance of a thermistor changes with temperature; the thermistor can be an NTC resistor or a PTC resistor, without limitation. Alternatively, the temperature sensing element 3 can be a thermocouple, which measures temperature based on the Seebeck effect, the characteristic that two different materials generate an electromotive force under a temperature gradient.

[0076] For example, you can refer to Figure 6 In one embodiment, the temperature measuring element 3 can be a temperature sensor 31, which can be disposed inside the radiation structure 13 and configured to be electrically connected to the control module to feed back electrical signals to the control module.

[0077] For example, you can refer to Figure 7 In some embodiments, the temperature sensing element 3 can also be a temperature sensing film 32, which is configured and attached to the circumferential outer surface of the radiating structure 13. The temperature sensing film 32 has conductive paths, and through connection with the control module, current can flow through the conductive paths to generate an electrical signal. The control module can obtain the current temperature state based on the electrical signal. In some embodiments, the temperature sensing film 32 can be formed on the circumferential outer surface of the radiating structure 13 by screen printing. For example, a conductive material for forming the temperature sensing film 32 is provided; according to a preset pattern, the conductive material is printed on the circumferential outer surface of the radiating structure 13 by screen printing; a curing process is performed, and then the temperature sensing film 32 is formed. In other embodiments, the pre-formed temperature sensing film 32 can also be pasted onto the circumferential outer surface of the radiating structure 13.

[0078] In summary, the impedance section 21 can be disposed inside or outside the radiation structure 13; when disposed inside the radiation structure 13, the impedance section 21 can be a resistance wire 211; when disposed outside the radiation structure 13, the impedance section 21 can be a heating film 212. Furthermore, the impedance section 21 can be configured to have a temperature measurement function, or an additional temperature measuring element 3 can be configured specifically for temperature measurement.

[0079] In addition, the aerosol generating device may also include a detection element (not shown) that can detect changes in air pressure or airflow caused during the suction process, thereby identifying the suction action. This detection element can be a pressure sensor or an airflow sensor. The specific construction of pressure sensors and airflow sensors can be found in relevant technologies and will not be elaborated upon here.

[0080] The detection element is connected to the containment area 141. For example, see reference... Figure 2A connecting channel 4 can be formed by openings in the circumferential sidewalls of the outer conductor unit 11 and the housing 14 along a radial direction. One end of the connecting channel 4 connects to the detection element, and the other end connects to the housing area 141. Alternatively, a portion of the housing 14 can extend outside the outer conductor unit 11 to form an outer shell. A vent pipe extending towards the detection element is provided on the outer periphery of the outer shell, defining the connecting channel 4 and connecting the detection element and the housing area 141. Placing the connecting channel 4 outside the outer conductor unit 11 can, on the one hand, prevent aerosols from flowing through and condensing in the connecting channel 4; on the other hand, it can keep the detection element away from the heat source, avoiding malfunction of the detection element due to high temperature; and on the other hand, it can avoid drilling holes in the outer conductor unit 11, which has a positive impact on improving the sealing performance of the cavity 113.

[0081] To further illustrate this application, the following are several specific embodiments provided in detail:

[0082] Example 1

[0083] Please see Figures 1-5 These figures illustrate the construction and application of the aerosol generating device in this embodiment 1. In the resonant component 1, as... Figure 3 As shown, the outer conductor unit 11 can be cylindrical, with its first end 111 and second end 112 being open ends, defining a cylindrical wall.

[0084] Continue reading Figure 3 The impedance matching structure 12 may include a first cylindrical section 121, a second cylindrical section 122, and a sealing portion 123 arranged axially. The first cylindrical section 121 is located at the top and forms a receiving cavity 1211 for accommodating the lower end of the aerosol generating article 500; the function of the first cylindrical section 121 is to adjust the microwave parameters and reduce the frequency shift of the aerosol generating article 500 during the suction process. The second cylindrical section 122 forms an insertion cavity 1221 for inserting the radiation structure 13, and the sealing portion 123 is used to connect to and seal the second end 112 of the outer conductor unit 11.

[0085] The top end of the first cylindrical section 121 is an open end communicating with the receiving cavity 1211. The lower end of the radiating structure 13 can enter through this open end, pass through the receiving cavity 1211, and be fixed at the insertion cavity 1221. Furthermore, the diameter of the receiving cavity 1211 is larger than the diameter of the insertion cavity 1221 and larger than the outer diameter of the lower end of the receiving seat 14. The upper end of the receiving seat 14 can be installed at the first end 111 of the outer conductor unit 11, sealing the gap between the receiving seat 14 and the outer conductor unit 11. The lower end of the receiving seat 14 is disposed in the receiving cavity 1211, allowing the lower end of the aerosol generating article 500 to be positioned within the receiving cavity 1211. Additionally, a shielding cover can be provided between the upper end of the receiving seat 14 and one end of the outer conductor unit 11 to prevent microwave leakage.

[0086] Please see Figure 2 The bottom wall of the receiving seat 14 serves to support the aerosol generating product 500. The outer side of the bottom wall of the receiving seat 14 can contact the bottom wall of the first cylindrical section 121. To reduce the heat transfer from the receiving seat 14 to the impedance matching structure 12, a spacer 15 can be provided between the bottom of the receiving seat 14 and the impedance matching structure 12 to reduce the contact area between the receiving seat 14 and the impedance matching structure 12, thereby reducing heat transfer by increasing thermal resistance. The spacer 15 can be annular and attached to the outer side of the bottom wall of the receiving seat 14 for contact with the impedance matching structure 12; the contact area between the spacer 15 and the impedance matching structure 12 is smaller than the area of ​​the bottom wall of the receiving seat 14.

[0087] Please see Figure 3 Inside the receiving base 14, a boss 142 is formed on the inner side of its bottom wall, and a groove 143 is provided on the inner peripheral side wall of the receiving base 14. When the aerosol generating product 500 is inserted into the receiving base 14, the boss 142 at the bottom of the receiving base 14 and the groove 143 on its inner peripheral side wall can form an airflow channel on the outside of the aerosol generating product 500. During the suction stage, outside air can reach the bottom of the aerosol generating product 500 along the airflow channel and enter the interior of the aerosol generating product 500. Secondly, the airflow channel can be connected to the detection element through the connecting channel 4, so that the negative pressure generated inside the airway during the suction process can trigger the detection element, thereby realizing the control of the temperature curve during the heating process.

[0088] Please see Figure 2One end of the radiating structure 13 is inserted into the insertion cavity 1221, and the other end passes through the bottom wall of the receiving seat 14 and is located in the receiving area 141. Because the radiating structure 13 penetrates the bottom wall of the receiving seat 14 and extends to the receiving area 141, the aerosol generated by the aerosol generating article 500 during heating and atomization, or the condensate formed after the aerosol cools, easily leaks outward from the gap between the radiating structure 13 and the receiving seat 14, gradually spreading into the cavity 113 outside the receiving seat 14, causing abnormal function of the cavity 113. To improve this problem, a sealing structure (not shown) can be added at the gap between the radiating structure 13 and the receiving seat 14, or around the gap, to prevent aerosol or condensate from entering the cavity 113 outside the receiving seat 14. The sealing structure may include a silicone ring, which can be fitted onto the radiating structure 13 and located below the bottom of the receiving seat 14 to seal the gap between the radiating structure 13 and the receiving seat 14, forming a good seal. The sealing structure may also include sealant; after the radiating structure 13 is inserted into place, the sealant is filled in the gap between the radiating structure 13 and the receiving seat 14.

[0089] Secondly, such as Figure 2 As shown, a clamping structure 16 can be provided between the circumferential sidewall of the insertion cavity 1221 and the radiation structure 13. The contact area between the clamping structure 16 and the radiation structure 13 is smaller than the circumferential sidewall area of ​​the insertion cavity 1221. Understandably, during heating, heat can be conducted to the outer conductor unit 11 through the radiation structure 13, causing the surface temperature of the outer conductor unit 11 to rise, thus resulting in energy loss. By designing the clamping structure 16 to reduce the contact area between the radiation structure 13 and the impedance matching structure 12, heat loss can be effectively reduced.

[0090] Please see Figure 3 The clamping structure 16 may include a plurality of protrusions 161 arranged circumferentially at intervals on the circumferential sidewall of the insertion cavity 1221. These protrusions 161 are configured to abut against the circumferential sidewall of the radiation structure 13 to clamp and fix the radiation structure 13 with a combined force. The protrusions 161 may be surface structures, point structures, or a combination of surface and point structures. It should be noted that surface structures typically have a larger area, forming a surface with a certain shape and size, while point structures typically have a smaller area. For example, the protrusions 161 may be arc-shaped structures with an arc facing the radiation structure 13. The arc surfaces of each protrusion 161 may form a circle with a diameter approximately equal to the bottom diameter of the radiation structure 13 to achieve clamping of the radiation structure 13.

[0091] Please continue reading. Figure 3The radiating structure 13 can be a needle-shaped hollow structure. The tip of the radiating structure 13 can be configured as a pointed tip to facilitate insertion into the interior of the aerosol generating article 500. The taper of the pointed tip is less than 60°, preferably less than 35°. Understandably, the sharper the pointed tip, the easier it is to pierce the plug section 502 of the aerosol generating article 500, and the easier it will be for the user to insert the aerosol generating article 500. It can be further noted that the aerosol generating article 500 generally includes a shell, and a plug section 502, a matrix section 501, and a cellulose acetate section 503 disposed in the shell. The plug section 502, the matrix section 501, and the cellulose acetate section 503 are arranged sequentially in the shell, and the plug section 502 is disposed at the bottom of the shell and is used to seal the bottom end of the shell. The matrix section 501 is a key component for generating aerosols and forming them. The matrix section 501 may have a hollow channel 5011 extending through it axially, and a portion of the radiating structure 13 may be disposed within this hollow channel 5011. The cellulose acetate section 503 is located downstream of the matrix section 501 and is used to filter the aerosols and reduce their temperature. The downstream location here can be understood as the position along the aerosol flow direction relative to the matrix section 501.

[0092] Please refer to the following: Figure 4 After the radiating structure 13 is inserted into the aerosol generating article 500, the tip can be positioned at the matrix segment 501 of the aerosol generating article 500. Preferably, the tip does not extend beyond the matrix segment 501; more preferably, the distance between the tip and the top of the matrix segment 501 is greater than or equal to 0.5 mm. This is because if the tip is positioned too high, the material at the acetate segment 503 may melt during microwave heating, leading to the generation of odors and harmful components. Similarly, the surface temperature of the structural portion of the radiating structure 13 located at the plug segment 502 should not be too high, preferably not exceeding 500°C, and more preferably not exceeding 185°C. This is because if the surface temperature of the structural portion of the radiating structure 13 located at the plug segment 502 is too high, the material at the plug segment 502 may melt, resulting in the release of a large amount of harmful components.

[0093] The maximum diameter of the radiating structure 13 is less than or equal to the diameter of the hollow channel 5011 of the matrix segment 501 of the aerosol-generating article 500. Preferably, the maximum diameter of the radiating structure 13 is less than the diameter of the hollow channel 5011, and the difference between the diameter of the radiating structure 13 and the diameter of the hollow channel 5011 is less than 1 mm. This is because when the matrix segment 501 is heated, the hollow channel 5011 will shrink. If the diameter of the radiating structure 13 is too close to the diameter of the hollow channel 5011, a "pin-binding" situation will occur, that is, the sidewall of the hollow channel 5011 will tightly adhere to or wrap around the radiating structure 13, making it difficult to pull out the aerosol-generating article 500. On the other hand, if the maximum diameter of the radiating structure 13 differs significantly from the diameter of the hollow channel 5011, the efficiency of heat transfer to the matrix segment 501 will decrease, the heating response time will be longer, and the temperature of the heated object will decrease, which is undoubtedly detrimental to the heating of the matrix segment 501.

[0094] like Figure 4 As shown, the radiating structure 13 may include a conductive segment 131 in ohmic contact with the impedance matching structure 12, and a heating segment 132 for insertion into the aerosol generating article 500. The heating segment 132 may be integrally formed with the conductive segment 131. An additional radiating coating for improving radiative performance may also be deposited on the outer surface of the heating segment 132. For example, this radiating coating has a high emissivity in the infrared band and can be used for infrared temperature calibration so that infrared temperature measuring devices can accurately measure the temperature at the radiating structure 13.

[0095] The resistance heating module 2 is located inside the radiating structure 13. (See also...) Figure 5 The resistance heating module 2 may include a bracket 23, a resistance wire 211 wound around the outer periphery of the bracket 23, and two leads 22 respectively connected to the two ends of the resistance wire 211.

[0096] Please combine Figure 2 and Figure 5 Referring to the reference, the support 23 may include a sealing section 231 and a rod-shaped portion 232 connected to the top of the sealing section 231. The diameter of the rod-shaped portion 232 is smaller than the diameter of the sealing section 231, and the resistance wire 211 can be wound around the rod-shaped portion 232. The diameter of the sealing section 231 is approximately equal to the inner diameter of the radiating structure 13, so as to secure the support 23 inside the radiating structure 13. Preferably, before the resistance heating module 2 is installed in the radiating structure 13, a filler material can be injected into the radiating structure 13, which can be cured to reliably fix the resistance heating module 2 in the radiating structure 13.

[0097] The support 23 also includes an internal channel 233 formed in the sealing section 231 and the rod-shaped portion 232, and a wire groove 234 formed on the outer peripheral sidewall of the sealing section 231. One end of the resistance wire 211 is disposed in the internal channel 233, and the other end is disposed on the outside of the support 23. One of the two wires can extend into the internal channel 233 and be connected to one end of the resistance wire 211; the other wire is connected to the other end of the resistance wire 211, and a portion of the other wire can be embedded in the wire groove 234. Since the two wires are isolated by the support 23, there will be no short circuit problem; at the same time, the wire groove 234 can play a limiting role, preventing the wire installed in the wire groove 234 from moving arbitrarily.

[0098] The resistance wire 211 is made of a thermistor material, or the resistance wire 211 is made of two different metal materials and forms a thermocouple, so that the resistance wire 211 has the functions of heating and temperature measurement.

The remaining structure is the same as in Embodiment 1 and will not be described again here.

[0106] In this embodiment, such as Figure 9 As shown, the resistance heating module 2 includes a heating film 212 and two wires.

The heating film 212 can form a conductive path, and the two ends of the conductive path are respectively connected to the two wires to connect to the control module, thereby realizing heating by electricity.

[0107] The heating film 212 is made of a thermosensitive material, or it is made of two different metal materials and forms a thermocouple, so that the heating film 212 has both heating and temperature measurement functions.

[0108] In this embodiment, the radiating structure 13 can be a solid structure.

The remaining structure is the same as in Embodiment 1 and will not be described again here.
