Background Art

[0003] With the development and popularization of the heating non-combustion technology in the aerosol field, the application scope of aerosol generators is expanding. By heating the aerosol generating product with a heating structure, it is possible to generate an aerosol while the aerosol generating product is heated without combustion. The heating form of the aerosol generating product by air heating has attracted attention. The specific principle is that by heating the air, the heated air enters the aerosol generating product during suction to achieve heating. The aerosol generating product is heated uniformly, without generating local high-temperature points or having a very short local high-temperature time, resulting in a good taste of the aerosol after suction and fewer harmful substances.

[0004] In the heating of aerosol generating products by air heating, the heating structure for air heating is an important component. In related technologies, there is a problem that the heating speed of air by the heating structure is slow, so the user needs a long preheating time, which has an adverse impact on the user experience.

[0026] Figure 1 shows a diagram of the air heating suction process of an aerosol generator provided by a first embodiment of the present application. The aerosol generator includes a heating structure 1 and a heating cavity. The heating cavity is used to contain an aerosol generating product 2. The heating structure 1 heats the aerosol generating product 2, generating an aerosol for the user to inhale while heating the aerosol generating product 2 without combustion. As can be seen from Figure 1, solid arrows indicate the direction of air flow, and dotted arrows indicate the direction of heat flow. After the preheating of the heating structure 1 is complete, when the user inhales, air enters the heating structure 1, absorbs the heat of the heating structure 1 and becomes heated air, which then enters the aerosol generating product 2 from the heating structure 1, heating the aerosol generating product 2 and releasing an effective aerosol for the user to inhale while heating the aerosol generating product 2 without combustion.

[0027] In this application, the inventors have made a special design for the heating structure 1 with the aim of improving the rate of air heating, shortening the preheating time, and enhancing the user experience. Initially, in the design of the heating structure 1, the inventors adopted a configuration in which multiple axial through holes were provided in the heat exchange member and a heating element was inserted through the axial center of the heat exchange member. With this configuration, the heat from the heating element is directly transferred by thermal conduction to the contact surface between the heat exchange member and the heating element, and then transferred from the contact surface of the heat exchange member to the entire circumference of the heat exchange member. Although this configuration was able to improve the rate of air heating, it did not reach the ideal state. Based on this, the inventors conducted further research and realized a better heating structure 1.

[0028] In one embodiment, as shown in Figures 3 to 5, the heating structure 1 includes a heat-generating component 11 and a heat exchange member 12. The heat-generating component 11 generates heat after being energized and can emit thermal radiation of a predetermined wavelength. The heat exchange member 12 surrounds the heat-generating component 11 from the outside. The heat exchange member 12 has a plurality of passages 124 through which airflow passes. The heat exchange member 12 can heat the airflow passing through the passages 124 by transferring the heat emitted from the heat-generating component 11 and absorbing the thermal radiation emitted from the heat-generating component 11. It is common knowledge that any object with a temperature higher than absolute zero can generate thermal radiation, but in this application, the energy of the thermal radiation is not the radiant energy associated with the heat generated by a normal object, but rather thermal radiation of a predetermined wavelength generated by a specific structure specially designed by the inventors for the heat-generating component 11. Specifically, this may be thermal radiation of a predetermined wavelength emitted from a light source, or thermal radiation of a predetermined wavelength emitted when an infrared coating reaches a predetermined temperature after an infrared coating has been applied to the surface of a heating element.

[0029] In this invention, the heat generated by the heat-generating component 11 of the heating structure 1 is transferred to the heat exchange member 12 by thermal conduction, and the energy of the thermal radiation generated by the heat-generating component 11 is transferred to the heat exchange member 12 by thermal radiation. By using two types of heat transfer methods, thermal conduction and thermal radiation, the air heating rate by the heating structure 1 was improved and the preheating time was shortened.

[0030] In one embodiment, the heat-generating component 11 is inserted into the heat exchange member 12, and the heat and thermal radiation energy generated by the heat-generating component 11 diffuses from the inside to the outside of the heat exchange member 12. This prevents the outer circumference of the heat exchange member 12 from overheating and causing burns to the user from the housing of the aerosol generator.

[0031] In one embodiment, as shown in Figure 5, the heat-generating component 11 is located at the geometric center of the heat exchange member 12 and is configured to diffuse the energy generated by the heat-generating component 11 radially outward from the geometric center of the heat exchange member 12. More specifically, the heat-generating component 11 is located at the axial center of the heat exchange member 12, and the direction of extension of the heat-generating component 11 coincides with the axial direction of the heat exchange member 12. As a result, the absorption and diffusion of energy by the heat exchange member 12 is performed with respect to the geometric center, and the heating rate or heating rate is the same at positions with the same radius or distance from the geometric center in the heat exchange member 12.

[0032] In one embodiment, as shown in Figures 5 to 7, the heat-generating component 11 includes a light source and a housing 112. The light source generates heat after being energized and can emit the thermal radiation described above. The housing 112 covers the outside of the light source and allows the thermal radiation to pass through. The housing 112 conducts heat with the heat exchange member 12, so that the thermal radiation generated by the light source passes through the housing 112 and is projected onto the heat exchange member 12. The role of the housing 112 is to protect the light source, to enable mechanical connection and heat conduction between the light source and the heat exchange member 12, and to allow the thermal radiation emitted from the light source to pass through and transfer the heat of the thermal radiation to the heat exchange member 12 by thermal radiation.

[0033] The light source of the heat-generating component 11 is positioned along the axial direction of the heat exchange member 12, thereby enabling heat transfer in at least a large portion of the axial region of the heat exchange member 12 and improving the efficiency of axial heat transfer in the heat exchange member 12.

[0034] In one embodiment, as shown in Figures 5 and 8, the heat exchange member 12 has a long columnar structure, and a plurality of passages 124 penetrate the heat exchange member 12 along its axial direction. Each passage 124 is parallel to the center of symmetry of the heat generating component 11. The direction of heat transfer from the heat generating component 11 to the heat exchange member 12 is approximately perpendicular to the direction of extension of each passage 124. The light source of the heat generating component 11 is positioned along the axial direction of the passage 124, and heat transfer occurs in at least the majority of the axial region of the passage 124.

[0035] In one embodiment, as shown in Figures 9 and 10, the multiple passages 124 are uniformly distributed across the entire cross-section of the heat exchange member 12. Each passage 124 is parallel to the others. In another embodiment, the density of the multiple passages 124 across the entire cross-section of the heat exchange member 12 is adjusted according to the non-uniformity of heat transfer. Specifically, in the cross-section of the heat exchange member 12, heat transfer is faster at locations closer to the heat-generating component 11 than at locations further away from the heat-generating component 11. Based on this, the density of passages 124 located further away from the heat-generating component 11 is smaller than the density of passages 124 located closer to the heat-generating component 11.

[0036] In one embodiment, as shown in Figures 9 and 10, the cross-section of the heat exchange member 12 is circular, that is, the heat exchange member 12 has a cylindrical structure. In other embodiments, the cross-section of the heat exchange member 12 may be a polygon, an ellipse, an irregular shape, or other shapes. The irregular shape referred to here may be adapted according to the spatial shape that the aerosol generator provides to the heating structure 1. For example, this irregular shape may be a combination of polygons and curved shapes, a combination of polygons, a combination of curved shapes, and so on.

[0037] In one embodiment, as shown in Figures 9 and 10, each passage 124 has a square shape in the radial cross-section (transverse plane) of the heat exchange member 12. In other embodiments of the present application, each passage 124 may have a circular, elliptical, runaway shape, or polygonal shape in the radial cross-section of the heat exchange member 12, and should be understood that it is not the only shape of such passages.

[0038] In one embodiment, as shown in Figures 9 and 10, each passage 124 is distributed in a matrix-like manner along two mutually perpendicular radial directions of the heat exchange member 12. When viewed from above the heat exchange member 12, the outer edges of the outermost passages 124 in the region where all passages 124 exist lie on the same circumference. Air enters from one end of each passage 124, is heated upon contact with the inner wall of the passage 124, and flows out from the other end of the passage 124, thereby achieving rapid heating of the air by the heat exchange member 12.

[0039] In one embodiment, as shown in Figures 5 and 14, the heat exchange member 12 has a contact surface 1253 that contacts the outer surface of the heat-generating component 11 to conduct heat. Specifically, the housing 112 is in direct contact with the contact surface 1253, and the heat from the housing 112 is directly transferred to the heat exchange member 12 by heat conduction.

[0040] In one embodiment, as shown in Figure 5, the heat exchange member 12 has a non-contact surface 1263 in addition to the contact surface 1253. The non-contact surface 1263 is installed at a distance from the outer surface of the heat-generating component 11, thereby receiving thermal radiation emitted from the heat-generating component 11. Furthermore, the non-contact surface 1263 can also reflect thermal radiation emitted from the heat-generating component 11. In other embodiments of the present invention, as shown in Figure 14, it should be understood that the heat exchange member 12 does not need to have a non-contact surface 1263. In this case, the thermal radiation emitted from the heat-generating component 11 is directly radiated to the contact surface 1253 of the heat exchange member 12, received by the contact surface 1253, and diffused throughout the entire heat exchange member 12.

[0041] When the non-contact surface 1263 is installed, specifically, the non-contact surface 1263 is not in contact with the outer surface of the heat-generating component 11 and cannot receive heat through direct heat conduction. However, since thermal radiation emitted from the heat-generating component 11 is irradiated onto the non-contact surface 1263, some of the energy of the thermal radiation is absorbed by the non-contact surface 1263 and the physical structure forming the non-contact surface 1263, and the other part is reflected back to the non-contact surface 1263. The reflected thermal radiation either exchanges heat with the air, is reflected again by other parts of the non-contact surface 1263, or the heat is absorbed, or it is directly irradiated onto the physical structure forming the non-contact surface 1263 and the heat is absorbed. In short, heat is transmitted in the form of thermal radiation and ultimately absorbed.

[0042] The transfer of heat to the non-contact surface 1263 and the physical structure forming the non-contact surface 1263 in the form of thermal radiation is inherently faster than direct heat conduction. Furthermore, the thermal radiation is reflected by the non-contact surface 1263, and in the process, heat exchange occurs with the air or the non-contact surface 1263 and its physical structure. As a result, the energy of the thermal radiation is rapidly and sufficiently absorbed and exchanged, achieving rapid and sufficient heating of the heat exchange member 12. When air enters through the passage 124 of the heat exchange member 12, it is rapidly heated by the heat exchange member 12 and the heat-generating component 11, significantly improving the rate of air heating, shortening the preheating time of the aerosol generator, and allowing the user to immediately obtain an inhalation experience with excellent flavor right after use.

[0043] On the other hand, the non-contact surface 1263 is installed at a distance from the outer surface of the heat-generating component 11, so that the heat-receiving surface moves from the contact position with the heat-generating component 11 to a position away from it. As a result, thermal radiation is directly irradiated to a position away from the heat-generating component 11, and the heat directly reaches deep into a position far from the heat-generating component 11 in the form of thermal radiation, heating it up. Compared to a configuration in which heating is achieved simply by diffusing heat to the outside from the contact surface between the heat exchange member 12 and the heat-generating component 11, this enables more direct and rapid heating.

[0044] Furthermore, in this embodiment, although it appears that a portion of the contact area for direct heat conduction between the heat-generating component 11 and the heat exchange member 12 is lost in the axial direction, the heating rate of the air by the heating structure 1 is significantly improved because heat is transferred more rapidly in the form of thermal radiation.

[0045] In one embodiment, as shown in Figure 5, the non-contact surface 1263 is positioned to surround the heat-generating component 11 so that it can receive and / or reflect thermal radiation emitted from the entire circumference of the heat-generating component 11. That is, all thermal radiation emitted from the circumferential portion of the heat-generating component 11 corresponding to the non-contact surface 1263 is received and / or reflected by the non-contact surface 1263.

[0046] In one embodiment, as shown in Figure 5, a space 126 is formed between the non-contact surface 1263 and the outer surface of the heat-generating component 11, and air flows through the space 126. The space 126 communicates with a corresponding passage 124, and air flows into the space 126 through the passage 124. Due to the presence of the space 126, the heat-receiving surface moves to a position away from the contact point with the heat-generating component 11. As a result, thermal radiation is directly irradiated to a position away from the heat-generating component 11, and the heat reaches deep into a position far from the heat-generating component 11 in the form of thermal radiation, heating it directly. Compared to a configuration in which heating is achieved simply by diffusing heat to the outside from the contact surface between the heat exchange member 12 and the heat-generating component 11, this enables more direct and rapid heating.

[0047] In one embodiment, as shown in Figure 5, the space 126 is positioned to surround the heat-generating component 11, so that the non-contact surface 1263 within the space 126 can receive and / or reflect thermal radiation emitted from the entire circumference of the heat-generating component 11. That is, all thermal radiation emitted from the circumferential portion of the heat-generating component 11 corresponding to the space 126 is received and / or reflected by the non-contact surface 1263 within the space 126.

[0048] In one embodiment, the non-contact surface 1263 is installed symmetrically so as to surround the heat-generating component 11. The space 126 may be installed symmetrically so as to surround the heat-generating component 11, and the form and degree of heat exchange at each part of the non-contact surface 1263 are the same, so that heat is uniformly distributed throughout the heat exchange member 12 and the entire heat exchange member 12 is heated uniformly. Specifically, the non-contact surface 1263 may be made up of fragmentary segments divided along the circumferential direction and installed symmetrically so as to surround the heat-generating component 11. Alternatively, the non-contact surface 1263 may be a continuous, integral surface in the circumferential direction and installed symmetrically so as to surround the heat-generating component 11. The space 126 may be made up of fragmentary segments divided along the circumferential direction and installed symmetrically so as to surround the heat-generating component 11, or it may be a continuous, integral space in the circumferential direction and installed symmetrically so as to surround the heat-generating component 11.

[0049] In one embodiment, as shown in Figures 5 and 8, at least one cavity 126 is formed inside the heat exchange member 12. The heat-generating component 11 is inserted into the cavity 126 and has an exposed surface that is exposed to the cavity 126. The inner wall of the cavity 126 becomes a non-contact surface 1263, and the cavity 126 becomes the aforementioned space 126, with the exposed surface being spaced apart from the inner wall of the cavity 126. The cavity 126 communicates with a corresponding passage 124, enabling air circulation. Air flows into the cavity 126 via the corresponding passage 124 and is heated by the heat inside the cavity 126. When the heat-generating component 11 emits thermal radiation, the thermal radiation is radiated uniformly into the cavity 126 along the circumferential direction of the heat-generating component 11. The inner wall of the cavity 126 receives some of the thermal radiation and reflects other thermal radiation toward other inner walls of the cavity 126.

[0050] In one embodiment, as shown in Figure 5, the heat-generating component 11 is installed in the cavity 126, at least in part. When the heat-generating component 11 emits thermal radiation, the exposed surface of the heat-generating component 11 that is exposed in the cavity 126 radiates thermal radiation uniformly into the cavity 126 along the circumferential direction. The inner wall of the cavity 126 receives some of the thermal radiation and reflects the other thermal radiation toward the inner wall at other locations in the cavity 126.

[0051] In one embodiment, as shown in Figures 5 and 8, there are at least two cavities 126, each cavity 126 spaced apart along the axial direction of the heat exchange member 12, and the heat-generating component 11 is inserted into at least one cavity 126. By spaced apart at least two cavities 126 along the axial direction of the heat exchange member 12, thermal radiation radiated from different axial positions of the heat-generating component 11 is received and reflected by different cavities 126. This allows different axial positions of the heat exchange member 12 to be heated synchronously, improving the overall heating rate of the heat exchange member 12. In other embodiments of the present invention, it should be understood that if the axial length of the heat exchange member 12 is short, there may be only one cavity 126, and if the axial length of the heat exchange member 12 is long, there may be three, four or more cavities 126, each cavity 126 spaced apart along the axial direction of the heat exchange member 12.

[0052] In one specific embodiment, as shown in Figures 8 to 13, the heat exchange member 12 has two cavities 126 formed therein, which are designated as the first cavity 126a and the second cavity 126b. The first cavity 126a and the second cavity 126b are installed spaced apart along the axial direction of the heat exchange member 12, so that each position of the heat exchange member 12 in the axial direction is heated uniformly.

[0053] In one embodiment, as shown in Figures 5 and 8, the cavity 126 is spherical, that is, the inner wall of the cavity 126 is spherical. Because reflection by the spherical surface is more uniform, the inner wall of the cavity 126 can uniformly reflect thermal radiation to the other inner walls of the cavity 126, enabling uniform heating of the heat exchange member 12. In other embodiments of the present application, the cavity 126 described above may be spindle-shaped or rectangular, or may be other polyhedral shapes other than rectangular, and it should be understood that it is not uniquely limited herein.

[0054] In one embodiment, as shown in Figure 5, the heat exchange member 12 has a mounting hole 125 that extends along its axial direction, and the heat generating component 11 is inserted into the mounting hole 125, with the inner wall of the mounting hole 125 becoming the contact surface 1253.

[0055] In one embodiment, as shown in Figures 5 and 8, the mounting holes 125 extend upward from the center of the bottom of the heat exchange member 12 along the axial direction of the heat exchange member 12, and extend to below the top of the heat exchange member 12. The inner diameter of the mounting holes 125 matches the outer diameter of the heat generating component 11. When the heat generating component 11 is inserted into the mounting holes 125 from the center of the bottom of the heat exchange member 12, the outer wall of the heat generating component 11 abuts against the inner wall of the mounting holes 125 and forms an interlocking fit, thereby transferring heat from the heat generating component 11 to the heat exchange member 12. When the heat generating component 11 generates heat, the heat is transferred to the inner wall of each mounting hole 125 and diffused throughout the heat exchange member 12, raising the temperature of the entire heat exchange member 12, and the air flowing through each passage 124 comes into contact with the inner wall of the passage 124 and is rapidly heated. Furthermore, as air flows through the passage 124 communicating with the mounting hole 125, the heat from the heat-generating component 11 may be carried away by the air. In other embodiments of the present invention, the mounting hole 125 may not be located at the center of the heat exchange member 12, or it may penetrate the heat exchange member 12 along the axial direction, and is not limited herein.

[0056] In one embodiment, as shown in Figures 9 and 10, the heat exchange member 12 is installed in a segment structure along its axial direction. The heat exchange member 12 may include at least two heat exchange subunits. Each heat exchange subunit is installed so as to be joined sequentially along the axial direction of the heat exchange member 12. At one end of the heat exchange subunit or at both opposing ends, a cavity is formed by recessing inward, and a cavity 126 is formed by butting the two opposing cavities of two adjacent heat exchange subunits together. In this case, if the cavity 126 is installed inside the heat exchange member 12, processing is inconvenient, but by installing it as described above, processing of the cavity 126 can be made easier.

[0057] In one embodiment, the non-contact surface 1263 is provided with a surface structure to enhance its ability to absorb thermal radiation. Specifically, the surface structure is installed on the inner wall of the cavity 126, and by increasing the ability of the non-contact surface 1263 to absorb thermal radiation, the heat absorption capacity of the heat exchange member 12 is enhanced, improving the heating rate of the heat exchange member 12, reducing heat loss, and saving thermal energy.

[0058] In one embodiment, the surface structure is a heat radiation absorbing coating. Specifically, by applying a heat radiation absorbing coating to the inner wall of the cavity 126, the heat absorption capacity of the non-contact surface 1263 is increased. Specifically, the heat radiation absorbing coating is made of a material such as tungsten trioxide or tin antimony oxide.

[0059] In another embodiment, the surface structure may be a colored layer formed on the inner wall of the cavity 126, specifically a colored layer having a darker color than the heat exchange member 12, thereby increasing the heat absorption capacity of the non-contact surface 1263. Specifically, the colored layer may be a black dye layer or a dark green dye layer. Furthermore, it is also possible to increase the heat absorption capacity of the heat exchange member 12 by forming the heat exchange member 12 itself with a black material.

[0060] In further embodiments of the present invention, the above-described surface structure may be a fine uneven structure formed on the inner wall of the cavity 126. That is, by applying an uneven surface treatment to the inner wall of the cavity 126, the roughness of the inner wall of the cavity 126 is increased, thereby enhancing the heat absorption capacity of the non-contact surface 1263. Specifically, when forming each heat exchange subunit, it is possible to form a fine uneven structure on the inner wall of the cavity 126 as well.

[0061] Selectively, the heat exchange member 12 may be manufactured from an aluminum alloy, ceramic, or graphite material, thereby ensuring that the heat exchange member 12 has a good heat conduction effect. Each passage 124 and cavity 126 can be formed by CNC machining or forging.

[0062] In one embodiment, the heat-generating component 11 is designed to be detachably and replaceably connected to the heat exchange member 12. For example, the heat-generating component 11 is detachably connected to the heat exchange member 12 by means of locking, interlocking, bonding, or locking of a fastening member. This allows for maintenance or replacement of either the heat-generating component 11 or the heat exchange member 12, by separating them and replacing them. In other embodiments of the present invention, the heat-generating component 11 and the heat exchange member 12 can also be connected as a single integrated structure. For example, combining them by crimping or secondary injection molding enables a robust connection and high mounting accuracy between the heat-generating component 11 and the heat exchange member 12.

[0063] In one specific embodiment, as shown in Figures 5 and 7, the thermal radiation emitted from the light source is a third type of infrared radiation. Infrared radiation is an electromagnetic wave with a longer wavelength than visible light, with wavelengths ranging from 770 nanometers to 1 millimeter, and located outside the visible light spectrum. Infrared radiation has a significant thermal effect, and when irradiated onto the heat exchange member 12, it can rapidly raise the temperature of the heat exchange member 12.

[0064] In one specific embodiment, as shown in Figures 5 and 7, the light source is a filament 111, and the material of the filament 111 may be a metallic tungsten filament, a carbon filament, a carbon sheet, or other infrared-emitting material. The filament 111 is installed to be wound in a spiral shape and has two output ends, the two output ends extending outward from the bottom end of the housing 112 and electrically connected to an external power source. Specifically, as shown in Figure 7, the filament 111 includes a first straight section 1111, a spiral section 1112, and a second straight section 1113. The first straight section 1111 is elongated and rod-shaped, its top end connected to the top end of the spiral section 1112. The spiral section 1112 is spiral-shaped and installed wound around the first straight section 1111. The second straight section 1113 is elongated and rod-shaped, its top end connected to the bottom end of the spiral section 1112. The second straight section 1113 is parallel to the bottom of the first straight section 1111 and is installed at a distance from it. Both the bottom end of the second straight section 1113 and the bottom end of the first straight section 1111 are electrically connected to an external power supply.

[0065] In one embodiment, as shown in Figures 5 to 7, the housing 112 includes a cylindrical portion 1121 and an arc portion 1122. The cylindrical portion 1121 is cylindrical in shape and has an opening at its bottom. The bottom end of the arc portion 1122 is connected to the top end of the cylindrical portion 1121, and the outer diameter of the arc portion 1122 gradually decreases from the bottom end to the top end, converging at the top end to form a tip. Specifically, the arc portion 1122 has a rotating body structure, and the side walls of the arc portion 1122 are installed projecting outward in an arc shape. The wall thickness of the cylindrical portion 1121 is kept constant from the bottom end to the top end, and the wall thickness of the arc portion 1122 is also kept constant from the bottom end to the top end, so that the wall thickness of the cylindrical portion 1121 and the wall thickness of the arc portion 1122 are the same. The outer wall of the cylindrical portion 1121 and the outer wall of the arc portion 1122 are smoothly connected, and the inner wall of the cylindrical portion 1121 and the inner wall of the arc portion 1122 are smoothly connected. The cylindrical portion 1121 and the arc portion 1122 are connected as a single structure, that is, the housing 112 is integrally molded from a transparent material. For example, the housing 112 may be made of fired transparent quartz, or it may be integrally injection molded from a transparent plastic material. In the housing 112 of this embodiment, the installation of the arc portion 1122 seals the top of the housing 112 with an arc structure, increasing the heat dissipation and radiant area of ​​the top of the housing 112, and improving the heating rate of the heat exchange member. Furthermore, by designing the top in an arc shape, the light rays can be treated to improve the uniformity of the light distribution.

[0066] As shown in Figures 5 to 7, the housing 112 covers the outside of the filament 111, and the filament 111 is positioned at the center of the housing 112. An end cover 113 is provided at the bottom of the housing 112. The end cover 113 seals the opening at the bottom of the housing 112, thereby positioning the filament 111 in a relatively sealed environment. The bottom ends of the first straight section 1111 and the second straight section 1113 of the filament 111 extend through the end cover 113 to the outside of the housing 112, so the end cover 113 also serves to mount the filament 111.

[0067] In one embodiment, a second infrared coating is applied to the outer surface of the housing 112, and when the second infrared coating reaches a second predetermined temperature, it can emit a second infrared radiation. Specifically, when the filament 111 generates heat due to the application of current, the heat generated from the filament 111 is transferred to the housing 112, and the temperature of the second infrared coating on the housing 112 rises. When the temperature of the second infrared coating reaches a second predetermined temperature, the second infrared coating emits a second infrared radiation to the heat exchange member 12. That is, after current is applied to the filament 111, the heat exchange member 12 can not only receive the heat emitted from the housing 112, but can also absorb the thermal radiation emitted from the filament 111 and the second infrared radiation emitted from the second infrared coating. Triple heating enables rapid heating of the heat exchange member 12, allowing heat to quickly diffuse to each part of the heat exchange member 12, resulting in uniform heating of the heat exchange member 12, high power utilization rate, and low energy consumption.

[0068] Specifically, the second infrared coating may be formed by uniformly applying an infrared material to the outer surface of the housing 112, by spraying an infrared material onto the outer surface of the housing 112, or by secondary injection molding or 3D printing.

[0069] Selectively, the infrared material may be a nanoceramic coating material. After absorbing infrared radiation emitted from the filament, the nanoceramic coating material's own temperature rises to 500°C to 700°C, and it emits infrared radiation to heat the heat exchange member 12.

[0070] In another embodiment of the present invention, the heating component 11 may be of other types. For example, the heating component 11 includes a heating element with a first infrared coating applied to its surface. The heating element is connected to an external power source and is capable of generating heat after being energized. After generating heat, the heating element transfers heat to the heat exchange member 12. When the heating element generates heat, the temperature of the first infrared coating on the surface of the heating element rises, and when the first infrared coating reaches a first predetermined temperature, it can generate first infrared rays and radiate them toward the heat exchange member. That is, the heat exchange member can simultaneously receive the heat transferred from the heating component 11 and the first infrared rays. This enables rapid heating of the heat exchange member 12, allows heat to quickly diffuse to each part of the heat exchange member 12, heats the heat exchange member 12 uniformly, has a high power utilization rate, and keeps energy consumption low.

[0071] Specifically, the heating element may be an electromagnetic heating element. In this case, the heat exchange member 12 may be made of graphite or a graphite alloy material. When the electromagnetic heating element is connected to an AC power source, the AC power source supplies AC power to the electromagnetic heating element, which generates an alternating magnetic field. Due to the skin effect, the resistance of the electromagnetic heating element increases, causing it to heat up, thereby heating the heat exchange member 12. The heat exchange member 12 itself is also affected by the magnetic field, generating eddy currents and heating up to some extent. In other embodiments of the present invention, the heating element described above may be a resistance heating element or a ceramic heating element, and it should be understood that it is not uniquely limited to these.

[0072] Selectively, the shape of the heating element may be designed to be similar to that of the filament 111 described above, and such a description will be omitted here. Of course, the heating element may be designed to have a U-shaped structure or a sheet-like structure, etc.

[0073] In one embodiment, the first infrared coating may be formed directly on the surface of the heating element, specifically on the surface of the heat-generating portion of the heating element. When the heating element generates heat, the first infrared coating also generates heat and emits first infrared rays. In other embodiments of the present invention, it should be understood that an external cover may be provided over the surface of the heating element, the heat from the heating element may be conducted to the heat exchange member 12 by the external cover, and the first infrared coating may be formed on the surface of the external cover.

[0074] Specifically, the first infrared coating may be formed by uniformly applying an infrared material to the outer surface of the heating element, by spraying an infrared material onto the outer surface of the heating element, or by secondary injection molding or 3D printing.

[0075] Selectively, the infrared material may be a nanoceramic coating material. After absorbing infrared radiation emitted from the filament, the nanoceramic coating material's own temperature rises to 500°C to 700°C, and it emits infrared radiation to heat the heat exchange member 12.

[0076] Specifically, as shown in Figures 9 and 10, the heat exchange member 12 includes a case 121, a plurality of first connecting plates 122, and a plurality of second connecting plates 123. The case 121 is cylindrical, and each first connecting plate 122 is formed inside the case 121 and is installed sequentially at equal intervals along a first direction X. Each first connecting plate 122 extends along a second direction Y, and its opposing ends in the second direction Y are connected to opposing inner walls of the case 121 in the second direction Y. Each second connecting plate 123 is formed inside the case 121 and is installed sequentially at equal intervals along the second direction Y. Each second connecting plate 123 extends along a first direction X, and its opposing ends in the first direction X are connected to opposing inner walls of the case 121 in the first direction X. Here, the first direction X and the second direction Y are set to be mutually orthogonal and correspond to the mutually perpendicular radial directions of the heat exchange member 12, respectively. The distance between two adjacent first connecting plates 122 is equal to the distance between two adjacent second connecting plates 123. Each first connecting plate 122 and each second connecting plate 123 are connected orthogonally to each other, forming a matrix-like arrangement of rectangular passages 124.

[0077] Selectively, the opposing ends of the first connecting plate 122 are integrally connected to the case 121, and the opposing ends of the second connecting plate 123 are also integrally connected to the case 121. That is, the case 121, the first connecting plate 122, and the second connecting plate 123 may be integrally molded.

[0078] In one embodiment of the present invention, by installing the heat exchange member 12 in a segment structure, the cases 121, first connecting plate 122, and second connecting plate 123 of each heat exchange subunit can be integrally molded, and then the heat exchange subunits can be joined sequentially. For example, the heat exchange subunits can be connected by adhesive or crimping.

[0079] Specifically, the heat exchange member 12 includes three heat exchange subunits, which are, from top to bottom, the first heat exchange subunit 12a, the second heat exchange subunit 12b, and the third heat exchange subunit 12c. The first heat exchange subunit 12a, the second heat exchange subunit 12b, and the third heat exchange subunit 12c are all constructed by integrally molding a case 121, a first connecting plate 122, and a second connecting plate 123. Furthermore, the cases 121, the first connecting plate 122, the second connecting plate 123, and the passage 124 of the first heat exchange subunit 12a, the second heat exchange subunit 12b, and the third heat exchange subunit 12c are all installed in a similar manner, corresponding from top to bottom.

[0080] In this embodiment, a housing is further installed on the outside of the heat exchange member 12. After sequentially stacking and joining the first heat exchange subunit 12a, the second heat exchange subunit 12b, and the third heat exchange subunit 12c, the housing can be used to position and lock the first heat exchange subunit 12a, the second heat exchange subunit 12b, and the third heat exchange subunit 12c. This eliminates the need to install connecting structures between the first heat exchange subunit 12a, the second heat exchange subunit 12b, and the third heat exchange subunit 12c, thereby simplifying the structure and assembly of the first heat exchange subunit 12a, the second heat exchange subunit 12b, and the third heat exchange subunit 12c. It should be understood that in other embodiments of the present application, the first heat exchange subunit 12a, the second heat exchange subunit 12b, and the third heat exchange subunit 12c may also be connected by adhesive or interlocking, and are not the only such methods.

[0081] Furthermore, the heat exchange member 12 includes a first heat exchange subunit 12a, a second heat exchange subunit 12b, and a third heat exchange subunit 12c. Of these, the first heat exchange subunit 12a and the second heat exchange subunit 12b are joined at the location of the first cavity 126a. Specifically, the first heat exchange subunit 12a has a first cavity 1261a, and the second heat exchange subunit 12b has a second cavity 1262a. When the first heat exchange subunit 12a and the second heat exchange subunit 12b are joined to each other, the first cavity 126a is formed by the first cavity 1261a and the second cavity 1262a facing each other and enclosing each other. Similarly, the second heat exchange subunit 12b and the third heat exchange subunit 12c are joined at the location of the second cavity 126b. Specifically, the second heat exchange subunit 12b has a third cavity 1261b, and the third heat exchange subunit 12c has a fourth cavity 1262b. When the second heat exchange subunit 12b and the third heat exchange subunit 12c are joined together, the third cavity 1261b and the fourth cavity 1262b face each other and surround the second cavity 126b, thereby forming the second cavity 126b.

[0082] Furthermore, as shown in Figure 8, the two cavities 126 divide the mounting hole 125 into two parts, namely the first hole portion 1251 and the second hole portion 1252. The first hole portion 1251 extends axially from the center of the bottom of the heat exchange member 12 to the first cavity 126a, and the second hole portion 1252 extends from the top of the first cavity 126a to the bottom of the second cavity 126b. In other words, in the axial direction of the heat exchange member 12, the first hole portion 1251, the first cavity 126a, the second hole portion 1252, and the second cavity 126b are installed in sequential communication. The heat-generating component 11 sequentially penetrates the first hole 1251, the first cavity 126a, the second hole 1252, and the second cavity 126b along the axial direction, and the top of the heat-generating component 11 is positioned just below the top inner wall of the second cavity 126b, thereby enabling the heat from the heat-generating component 11 to be absorbed by the heat exchange member 12.

[0083] In one embodiment, as shown in Figure 8, the axial lengths of the first hole 1251 and the second hole 1252 are both smaller than the axial lengths of the first cavity 126a and the second cavity 126b. Since the heating effect of the heat exchange member 12 due to thermal radiation emitted from the heat-generating component 11 is more significant than the heating effect of the heat exchange member 12 due to heat emitted from the heat-generating component 11, in this application, the heating efficiency of the heat exchange member 12 is improved by making the axial lengths of the first cavity 126a and the second cavity 126b as large as possible.

[0084] In one embodiment, as shown in Figures 5 and 8, the inner diameter of the cavity 126 is larger than the inner diameter of the mounting hole 125, thereby allowing the surface of the heat-generating component 11 to be installed with a gap between it and the inner wall of the cavity 126. The installation of the cavity 126 increases the absorption area of ​​the heat exchange member 12 for thermal radiation. More specifically, the cavity 126 penetrates at least 80% of the radius of the heat exchange member 12 in the radial direction, thereby allowing the cavity 126 to quickly receive the thermal radiation emitted from the heat-generating component 11.

[0085] Within this structure, the passages 124 are distributed throughout the heat exchange member 12. Each passage 124 is formed by the mutually orthogonal encirclement of the first connecting plates 122 and the second connecting plates 123. Therefore, the installation of the mounting hole 125 corresponds to the removal of the space defined by the first connecting plates 122 and the second connecting plates 123 at the positions corresponding to the mounting hole 125 of the heat exchange member 12. In other words, the inner wall of the mounting hole 125 is formed by combining the first connecting plates 122 and the second connecting plates 123 at the positions corresponding to the mounting hole 125. Specifically, the contact surface 1253 is a combination of the first connecting plates 122 and the second connecting plates 123 at the positions corresponding to the mounting hole 125. Furthermore, the mounting hole 125 is installed in communication with the passage 124 that encircles the mounting hole 125 and the passage 124 at the top. When the heat-generating component 11 generates heat, the heat is transferred to each of the first connecting plates 122 and each of the second connecting plates 123, causing the temperature of the entire heat exchange member 12 to rise. The air flowing through each passage 124 comes into contact with each of the first connecting plates 122 and each of the second connecting plates 123, and they are rapidly heated. Furthermore, as the air flows through the passage 124 that communicates with the mounting hole 125, some of the heat from the heat-generating component 11 may be carried away by the air.

[0086] In one embodiment, the aerosol generating product 2 contains a tobacco medium, and a suction port is provided at one end of the aerosol generating product 2. The heating structure 1 is installed at the other end of the aerosol generating product 2 and may be mechanically connected to the aerosol generating product 2 or installed independently of the aerosol generating product 2. The heating structure 1 can be directly connected to an external power supply, and the heating structure 1 generates heat by supplying power to the heating structure 1 from the external power supply. When the user inhales through the suction port, air enters the heating structure 1 and is rapidly heated, and the heated air then enters the aerosol generating product 2, heating the medium inside the aerosol generating product 2 and releasing an effective aerosol for the user to inhale.

[0087] Furthermore, the aerosol generator further includes a sensor located in the airflow path. When a user inhales through the suction port, the sensor detects the fluid change and feeds it back to the heating structure 1, which then begins heating the air and the medium. However, the placement of the sensor prevents the heating structure 1 from heating when the user is not inhaling through the suction port, thereby saving energy consumption.

[0088] As shown in Figure 2, another selectable configuration of the heating medium of the present invention is shown. In this selectable configuration, the heating structure 1 described above not only heats the medium by heating the air, but also has a heating element 3 installed in the heating cavity, with the heating structure 1 installed upstream of the heating cavity. The heating element 3 is installed so as to surround the aerosol generating product 2 and can directly heat the aerosol generating product 2. Specifically, the heating element 3 can transfer heat to the medium by thermal conduction and can also transfer thermal radiation energy to the medium by thermal radiation, thereby enabling heating of the medium. According to this selectable configuration, the medium can be heated more flexibly and sufficiently by combining different heating modes, the active ingredients of the medium can be sufficiently released, and different flavors can be generated.

[0089] Selectively, the heating element 3 may be installed so as to surround the outer periphery of the aerosol generating product 2, thereby heating the aerosol generating product 2, or it may be inserted into the interior of the aerosol generating product 2, thereby heating the aerosol generating product 2.

[0090] Selectively, the heating structure 1 may be placed below the aerosol generating product 2 to heat the aerosol generating product 2, or it may be placed on the outer periphery of the aerosol generating product 2 to heat the aerosol generating product 2.

[0091] Based on the above, the heating structure in the embodiment of the present application has at least the following advantages.

[0092] 1. The heat emitted from the heat-generating component 11 is transferred to the heat exchange member 12 by thermal conduction, and the energy contained in the thermal radiation emitted from the heat-generating component 11 is transferred to the heat exchange member 12 by thermal radiation. By using both thermal conduction and thermal radiation as heat transfer methods, the heating rate of the air by the heating structure is improved, and the preheating time is shortened.

[0093] 2. By forming a non-contact surface 1263 on the heat exchange member 12, the absorption area of ​​the heat exchange member 12 for thermal radiation is increased, improving the heating rate of the heat exchange member 12. When air enters through the passage 124 of the heat exchange member 12, it is rapidly heated by the heat exchange member 12 and the heat-generating component 11, significantly improving the heating rate of the air, shortening the preheating time of the aerosol generator, and allowing the user to immediately obtain an inhalation experience with excellent flavor right after use.

[0094] 3. By installing a surface structure on the non-contact surface 1263 to enhance the ability to absorb thermal radiation, the ability of the heat exchange member 12 to absorb thermal radiation is improved, the heating rate of the heat exchange member 12 is increased, heat loss is reduced, and thermal energy is saved.

[0095] IV. By inserting the heat-generating component 11 into the heat exchange member 12, the heat and thermal radiation energy from the heat-generating component 11 diffuses from the inside to the outside of the heat exchange member 12. This prevents the outer circumference of the heat exchange member 12 from overheating and causing burns to the user from the housing of the aerosol generator.

[0096] The foregoing are merely selective embodiments of the present invention and do not limit the present invention. Those skilled in the art can make various modifications and alterations to the present invention. Any modification, equivalent substitution, or improvement that does not deviate from the spirit and principles of the present invention should be considered within the scope of the claims.
