[0002] The atomizing device provides a similar taste to traditional cigarettes while avoiding the tar and particulate matter. It can be used as a substitute for traditional cigarettes and for smoking cessation, offering convenience and a healthier option. Existing atomizing devices can heat the cigarette, which is made of tobacco and other materials. Users place the cigarette inside the device, and the device heats it to produce a roasted tobacco aroma during inhalation, enhancing the user experience. However, existing atomizing devices often heat the cigarette unevenly, leading to localized scorching and affecting the stability of the roasted tobacco aroma, thus impacting the user experience. Therefore, there is room for improvement. Summary of the Invention

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Existing atomizing devices heat the first substrate unevenly, which can easily lead to localized scorching of the first substrate, affecting the stability of the aroma of flue-cured tobacco and thus impacting the user experience.

[0033] The following is for reference. Figures 1-10 The device body 100 described in this embodiment of the invention has low installation cost, allows the first substrate 43 and the heating element 12 to be spaced apart to reduce suction resistance, and avoids excessive local heating of the first substrate 43 by the heating element 12, ensuring heating uniformity and thus ensuring the stability of the baking effect on the first substrate. At the same time, the heating element 12 can perform non-penetrating three-dimensional heating of the first substrate 43 through both thermal radiation and thermal convection coupling, improving heating efficiency and enhancing the user experience.

[0034] like Figures 1-10As shown, the main body 100 of the device according to an embodiment of the present invention includes: a rod 1, a positioning member 41 and a heating member 12.

[0035] The rod body 1 is provided with a mounting cavity 4, a positioning member 41 is provided in the mounting cavity 4, and a heating member 12 is provided in the mounting cavity 4 and defines a heating cavity 44. The heating cavity 44 is adapted to accommodate a first substrate 43. The inner wall of the positioning member 41 and the inner wall of the heating member 12 are spaced apart so that the first substrate 43 and the heating member 12 are spaced apart.

[0036] This invention relies on the innovative architecture of NHP (Noncombustion Heat Control Platform). Through its highly integrated precision temperature control system and underlying technology framework, it establishes industry performance benchmarks while providing users with a system-level solution that combines excellent safety with an ultimate sensory experience.

[0037] Specifically, the main body 100 can be used as part of the atomizing device 1000, and the main body 100 is provided with a rod 1. The rod 1 can be constructed as an integral molded part for installing the components in the main body 100 and for protecting the internal components, thereby ensuring the operational reliability of the atomizing device 1000. The rod 1 forms an installation cavity 4, and the main body 100 is provided with a heating element 12. The heating element 12 is installed in the installation cavity 4 and forms a heating cavity 44. The heating cavity 44 is suitable for accommodating the first substrate 43, so that the heating element 12 can heat the first substrate 43. The first substrate 43 can be a cigarette or the like, made of tobacco or other materials. When the user smokes, the heating element 12 can roast the first substrate 43, so that the first substrate 43 can produce a roasted tobacco aroma, thereby enriching the user's taste and improving the user experience.

[0038] Furthermore, the main body 100 of the device is also provided with a positioning member 41. The positioning member 41 can be installed in the mounting cavity 4 of the rod body 1 by means of plugging or snapping. The positioning member 41 is provided with a positioning part 411. When the first substrate 43 is placed in the heating cavity 44, the positioning member 41 can support the first substrate 43, thereby limiting the relative position of the first substrate 43 in the heating cavity 44. The inner wall of the positioning member 41 is spaced apart from the inner peripheral wall of the heating element 12, so that when the inner wall of the positioning member 41 supports the first substrate 43, the first substrate 43 and the heating element 12 can be spaced apart. This can prevent the heating element 12 from overheating the first substrate 43, causing the first substrate 43 to scorch or other problems, ensuring the stability of the aroma of the flue-cured tobacco, and reducing the resistance of the airflow between the first substrate 43 and the heating element 12, thereby reducing the suction resistance.

[0039] In addition, the first substrate 43 and the heating element 12 are spaced apart, so that the heating element 12 can directly radiate heat to the first substrate 43 and heat the airflow between the first substrate 43 and the heating element 12 at the same time. This allows the first substrate 43 and the heating element 12 to form thermal convection coupling. As a result, the heating element 12 can perform non-penetrating three-dimensional heating of the first substrate 43 through both thermal radiation and thermal convection coupling, which improves heating efficiency and enhances the user experience. Moreover, the heating part 121 has a simple structure, which can reduce the installation cost while ensuring the heating effect.

[0040] According to the embodiment of the present invention, the device body 100, by spaced apart from the inner wall of the positioning member 41 and the inner wall of the heating member 12, allows the inner wall of the positioning member 41 to support the first substrate 43 when it is placed in the mounting cavity 4, thereby spaced apart from the heating member 12. This avoids excessive local heating of the first substrate 43 by the heating member 12, ensuring heating uniformity and reducing suction resistance. At the same time, the airflow generated when the user draws can flow between the heating member 12 and the first substrate 43, allowing the heating member 12 to perform non-penetrating three-dimensional heating of the first substrate 43 through both thermal radiation and thermal convection coupling, improving heating efficiency and enhancing the user experience. The device has a simple structure, low installation cost, better performance, and wider applicability.

[0041] In some embodiments, an annular guide channel 42 is formed within the positioning member 41, and the inner wall of the guide channel 42 defines the positioning portion 411.

[0042] Specifically, a ring-shaped guide channel 42 is formed inside the positioning member 41, and the guide channel 42 is connected to the heating chamber 44, so that the airflow in the guide channel 42 can flow into the heating chamber 44, or the airflow in the heating chamber 44 can flow into the guide channel 42. The first substrate 43 can be inserted into the guide channel 42, so that the guide channel 42 can guide and limit the first substrate 43, making it easier for the first substrate 43 to be placed in the mounting cavity 4, improving the convenience and accuracy of installation. The inner wall of the guide channel 42 can define the positioning part 411, so that the inner wall of the guide channel 42 can support the first substrate 43, so that the first substrate 43 is spaced apart from the heating member 12, ensuring the reliability of heating the first substrate 43.

[0043] When the first substrate 43 extends into the mounting cavity 4, at least a portion of the first substrate 43 can be placed in the heating cavity 44 of the heating element 12. There is an annular gap between the outer peripheral wall of the first substrate 43 and the inner peripheral wall of the heating element 12. When the airflow enters the annular gap, the heating element 12 can heat the airflow to form a high-temperature air curtain, and perform non-penetrating three-dimensional heating of the first substrate 43 in a way that couples thermal radiation and thermal convection, thereby improving heating efficiency and ensuring heating uniformity.

[0044] In actual setup, the first substrate 43 and the guide channel 42 are in clearance fit, and the clearance between the first substrate 43 and the guide channel 42 is smaller than the clearance between the first substrate 43 and the heating element 12. That is, the inner diameter of the heating element 12 is set to be larger than the inner diameter of the guide channel 42. This allows the positioning part 411 defined by the inner wall of the guide channel 42 to support and position the first substrate 43 while also allowing airflow to pass through the guide channel 42 into the heating chamber 44. This eliminates the need for additional structures and facilitates manufacturing.

[0045] In some other embodiments, the positioning part 411 is disposed on the guide channel 42 and protrudes from the guide channel 42.

[0046] Specifically, such as Figure 3 As shown, a positioning part 411 may be provided in the guide channel 42, and the positioning part 411 may be configured as a positioning protrusion, positioning block or positioning ring, etc. The positioning part 411 protrudes inward on the inner wall of the guide channel 42, so that the positioning part 411 can support the first substrate 43. At this time, the inner diameter of the heating element 12 and the guide channel 45 may be set to be equal, so that the inner peripheral wall of the heating element 12 is flush with the inner peripheral wall of the guide channel 45. In this way, the positioning part 411 can separate the outer peripheral wall of the first substrate 43 and the inner peripheral wall of the heating element 12 to avoid over-roasting of the first substrate 43 locally, and facilitate the flow of air between the first substrate 43 and the heating element 12, so that the airflow can carry the aroma of flue-cured tobacco to the user's oral cavity and ensure the user's experience.

[0047] In some embodiments, when the first substrate 43 passes through the guide channel 42 and extends into the heating chamber 44, a continuous annular gap is formed between the outer peripheral wall of the first substrate 43 and the inner peripheral wall of the heating chamber 44. When the user draws in negative pressure, external air enters the annular gap and is preheated by the wall of the heating chamber 44 during the flow process, thereby forming a dynamically flowing preheated air film on the outer periphery of the first substrate 43. The preheated air film constitutes an air curtain surrounding the first substrate 43. The air curtain works together with thermal radiation to perform non-contact heating of the first substrate 43 through the coupling of thermal radiation and thermal convection.

[0048] In some embodiments, the axis of the guide channel 42 and the axis of the heating cavity 44 are aligned.

[0049] Specifically, such as Figure 1 and Figure 3As shown, the positioning member 41 has a guide channel 42, and the first substrate 43 can be inserted into the guide channel 42, so that the positioning part 411 of the positioning member 41 can position the first substrate 43, ensuring the accuracy of the first substrate 43 in the mounting cavity 4. The axis of the guide channel 42 and the axis of the heating cavity 44 are coincident, that is, when the first substrate 43 is inserted into the guide channel 42 and the heating cavity 44, the distance between the outer peripheral wall of the first substrate 43 and the inner peripheral wall of the heating member 12 is the same in all circumferential directions, so that the heating effect of the heating member 12 on all parts of the outer peripheral wall of the first substrate 43 is the same. This can avoid the problem of excessive temperature in some parts of the first substrate 43 causing the aroma of the flue-cured tobacco to burn, so as to ensure the stability of the aroma of the first substrate 43 and improve the user experience.

[0050] In some embodiments, the axis of the guide channel 42 is coaxially arranged with the axis of the heating cavity 44, and the coaxiality tolerance between the inscribed circle formed by the positioning part 411 and the center line of the heating cavity 44 is limited to no more than 0.05 mm, so that the circumferential distribution uniformity deviation of the annular gap is less than 10%, thereby improving the consistency of the air curtain.

[0051] In some embodiments, the wall material or coating of the heating cavity 44 is configured to have an emissivity greater than 0.8 to enhance the contribution of thermal radiation heat transfer to the first substrate 43, thereby achieving non-contact three-dimensional heating of the first substrate 43 together with the thermal convection in the annular gap, and improving the heating effect.

[0052] In some embodiments, the positioning portion 411 includes at least three positioning protrusions, which are spaced apart circumferentially along the guide channel 42, and are used to support the positioning first substrate 43.

[0053] Specifically, the guide channel 42 is provided with a positioning part 411, and the positioning part 411 can be configured with at least three positioning protrusions, that is, the positioning protrusions can be three, four or five, etc. The at least three positioning protrusions are formed on the inner peripheral wall of the guide channel 42 and protrude into the guide channel 42. The at least three positioning protrusions are spaced apart along the circumference of the guide channel 42, so that the at least three positioning protrusions can support the first substrate 43 at at least three points in the circumference of the first substrate 43, thereby ensuring that the first substrate 43 is spaced apart from the inner peripheral wall of the heating element 12 at each point in the circumference, so as to ensure the heating effect of the first substrate 43 at each point in the circumference, improve the baking effect of the first substrate 43, and thus improve the user experience.

[0054] Furthermore, the protrusion dimensions of each positioning protrusion are the same, and the guide channel 42 and the heating element 12 are coaxially arranged. This ensures that when the first substrate 43 passes through the guide channel 42, the first substrate 43, the guide channel 42, and the heating element 12 are all coaxially arranged. Consequently, the distance between the first substrate 43 and the heating element 12 is the same at all points along the circumference, thus ensuring the consistency of the heating effect of the heating element 12 on all points along the circumference of the first substrate 43, ensuring the stability of the tobacco aroma of the first substrate 43, and thus improving the user experience.

[0055] In actual installation, the positioning part 411 can also be constructed as a positioning strip. The positioning strip extends circumferentially and at least two positioning strips are provided. The at least two positioning strips are distributed circumferentially spaced apart so that the positioning strip can support the first substrate 43 at multiple points in the circumferential direction. The inner wall shape of the positioning strip is set to fit the outer circumferential wall of the first substrate 43 to ensure the stability of the support for the first substrate 43 and ensure the reliability of the positioning part 411.

[0056] In some embodiments, the mounting cavity 4 extends along a first direction, and the inner wall of the positioning member 41 and the inner wall of the heating member 12 are spaced apart along a second direction, with the first and second directions perpendicular to each other. Figure 1 As shown, the mounting cavity 4 extends along the first direction, so that when the heating element 12 is installed in the mounting cavity 4, the heating cavity 44 also extends along the first direction, thereby allowing the first substrate 43 to be inserted along the first direction, and the inner wall of the positioning element 41 can support the first substrate 43 along the second direction. The first direction and the second direction are perpendicular, which can improve the stability of the support.

[0057] In some embodiments, there are multiple positioning elements 41, which are spaced apart along the extension direction of the mounting cavity 4, and the two ends of the heating element 12 respectively cooperate with the corresponding positioning elements 41.

[0058] Specifically, the positioning element 41 forms a guide channel 42, and the first substrate 43 can be inserted into the guide channel 42. Multiple positioning elements 41 are provided, spaced apart along the extension direction of the mounting cavity 4. The first substrate 43 can be sequentially inserted into the guide channel 42 of each positioning element 41, so that the multiple positioning elements 41 can respectively guide and support the first substrate 43 at various points along its length, ensuring the reliability of the positioning elements 41 in use. Figures 1-2 As shown, the two ends of the heating element 12 can be connected to two of the multiple positioning elements 41 by means of plugging or other means to fix the heating element 12, ensure the relative position between the heating element 12 and the first substrate 43, and thus ensure the stability of the heating effect of the heating element 12 on the first substrate 43.

[0059] In some embodiments, the inner diameter of the heating element 12 is set to d1, and the outer diameter of the first substrate 43 is set to d2, and the following conditions are met: 0.2mm≤d1-d2≤1mm, that is, the size of the gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 is set to be greater than or equal to 0.2mm and less than or equal to 1mm, so that the heating element 12 can heat the first substrate 43 through both thermal radiation and thermal convection coupling, thereby improving the heating effect, so that the airflow entering the annular gap under suction negative pressure can stably form an air curtain, so as to balance suction resistance and heating uniformity and reduce the risk of local scorching. In addition, the length of the first substrate 43 is set to be greater than the distance between two adjacent positioning elements 41, so that both ends of the first substrate 43 can be supported and positioned by the positioning elements 41.

[0060] Preferably, the inner diameter of the heating element 12 is set to d1, and the outer diameter of the first substrate 43 is set to d2, satisfying: 0.2mm≤d1-d2≤0.7mm, that is, the size of the gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 is set to be greater than or equal to 0.2mm and less than or equal to 0.7mm, ensuring that the heating element 12 can heat the first substrate 43 through both thermal radiation and thermal convection coupling, thereby improving the heating effect, so that the airflow entering the annular gap under suction negative pressure can stably form an air curtain, so as to balance suction resistance and heating uniformity and reduce the risk of local scorching. In addition, the length of the first substrate 43 is set to be greater than the distance between two adjacent positioning elements 41, so that both ends of the first substrate 43 can be supported and positioned by the positioning elements 41.

[0061] In actual testing, when the heating element 12 and the first substrate 43 are in a tightly coupled state, that is, when the single-sided gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 is about 0.15mm, the temperature distribution on the surface of the first substrate 43 is extremely close to the tube wall temperature of the heating element 12, with very low thermal resistance, high heat flux density, and extremely high uniformity of the thermal field. However, it is greatly affected by the roundness tolerance of the first substrate 43. If the first substrate 43 is slightly elliptical, local overheating is very likely to occur. In addition, the tolerance space between the heating element 12 and the first substrate 43 is small, and the friction when inserting or removing the first substrate 43 is extremely large, resulting in a poor user experience.

[0062] When the heating element 12 and the first substrate 43 are in standard design condition, that is, the single-sided gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 is about 0.25mm, it can be seen from the temperature cloud map characteristics that the air curtain between the first substrate 43 and the heating element 12 can form a stable heat buffer layer. Under the action of the positioning protrusion, the concentricity of the first substrate 43 in the heating cavity 44 can be ensured, so that the circumferential temperature gradient is small. The air curtain between the first substrate 43 and the heating element 12 not only conducts heat but also acts as a heat spreader, avoiding the first substrate 43 from scorching, while ensuring sufficient heating inside the first substrate 43, thus ensuring the baking effect of the first substrate 43.

[0063] When the heating element 12 and the first substrate 43 are in a loose coupling condition, that is, when the single-sided gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 is about 0.35mm, it can be seen from the temperature cloud map characteristics that the surface temperature of the first substrate 43 is significantly lower than the tube wall temperature of the heating element 12. The heat insulation effect of the air begins to appear, and in order to achieve the same baking temperature of the first substrate 43, the set temperature of the heating element 12 needs to be significantly increased, which leads to increased energy consumption. Furthermore, the increased air flow can easily lead to unstable axial temperature distribution, thus affecting the heating effect on the first substrate 43.

[0064] When the heating element 12 and the first substrate 43 are in an inefficient working condition, that is, when the single-sided gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 is about 0.5mm, the temperature cloud map shows that a clear low-temperature zone surrounds the first substrate 43, which leads to a significant decrease in the heating effect on the first substrate 43. The air curtain is too thick, which can block heat. As a result, even if the heating element 12 is heated at full power, the center temperature of the first substrate 43 may still not reach the required baking temperature. Furthermore, due to the large gap, the positioning protrusion provides poor support for the first substrate 43, which can easily lead to the first substrate 43 becoming eccentric. This can result in localized scorching and localized low temperatures in the first substrate 43, resulting in poor baking performance and affecting the user experience.

[0065] In actual setup, the first substrate 43 and the guide channel 42 are in a clearance fit, which makes the first substrate 43 have a small sway within the heating element 12, thereby making the gap value between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 have a small fluctuation.

[0066] Based on the above physical analysis, Table 1 below is a comparison table of the comprehensive efficiency of the four gap conditions:

[0067] According to Table 1 and Figure 10It can be seen that the optimal gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 is about 0.25 mm. That is, preferably, the gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 can be set to 0.25 mm.

[0068] In some embodiments, the heating element 12 includes a heat-conducting element 123 and a plurality of heating portions 121, a heating cavity 44 is formed in the heat-conducting element 123, and the plurality of heating portions 121 are spaced apart on the outer peripheral wall of the heat-conducting element 123 in the extending direction of the mounting cavity 4.

[0069] Specifically, the heating element 12 is installed inside the mounting cavity 4, and as follows: Figure 4 As shown, the heating element 12 is provided with a heat-conducting element 123 and a heating section 121. The heat-conducting element 123 is constructed as a metal tubular structure. The first substrate 43 can be inserted into the heat-conducting element 123. There are multiple heating sections 121, that is, there can be two, three or four heating sections 121. The multiple heating sections 121 are spaced apart on the outer peripheral wall of the heat-conducting element 123 along the extension direction of the mounting cavity 4. The heating section 121 can be constructed as a heating wire, etc. The heating section 121 can generate heat when energized, and then conduct heat to the heat-conducting element 123. The heat-conducting element 123 can conduct heat along the axial direction, thereby heating the first substrate 43 located in the heat-conducting element 123 to improve the heating uniformity of the first substrate 43 and improve the baking effect.

[0070] In some embodiments, the main body 100 of the device further includes a control module 23. Each heating element 121 is provided with a pin 122. The control module 23 is electrically connected to the plurality of heating elements 121 through the pin 122 to control the heating amount of each heating element 121.

[0071] Specifically, the main body 100 of the device is also provided with a control module 23, which is installed on the rod 1 and can be electrically connected to multiple heating parts 121 respectively, such as Figure 4 As shown, each heating element 121 is provided with a corresponding pin 122. The control module 23 can be electrically connected to multiple pins 122 via a wiring harness 232, thereby supplying power to each heating element 121 so that each heating element 121 heats the heat-conducting element 123, thereby uniformly heating the heat-conducting element 123 along the axial direction to ensure the uniformity of heating of the first substrate 43. Furthermore, the control module 23 can individually control the heat of each heating element 121 via the wiring harness 232, so that users can select the baking method of the first substrate 43 according to their preferences, thereby obtaining different baking aromas to meet different user needs.

[0072] In addition, when the user draws air from the atomizing device 1000, the control module 23 can acquire the user's drawing signal and adjust the power of the heating element 12 according to the drawing intensity, so that the airflow temperature in the annular gap between the heating element 12 and the first substrate 43 is maintained between 200°C and 300°C. The thermal resistance effect of the annular gap is used to prevent premature carbonization of the outer paper of the first substrate 43. In the initial stage of drawing, the control module 23 controls the heating element 12 to operate at the first power, so that a high-temperature air curtain is quickly established in the annular gap. In the continuous stage of drawing, the control module 23 controls the heating element 12 to switch to the second power for steady-state heating. The first power is greater than the second power to instantly increase the tube wall temperature of the heating element 12, thereby compensating for the heat carried away by the increased airflow speed and maintaining the stability of the "hot air curtain" in the annular gap.

[0073] In some embodiments, the main body 100 of the device further includes a heat insulation member 14, which is sleeved outside the heating member 12 and distributed radially apart from the heating member 12, and a heat insulation cavity 141 is formed in the heat insulation member 14.

[0074] Specifically, such as Figure 1 and Figure 3 As shown, the main body 100 of the device is also provided with a heat insulation component 14, which is installed in the mounting cavity 4. The heat insulation component 14 can be sleeved on the outside of the heating component 12, and the inner peripheral wall of the heat insulation component 14 and the inner peripheral wall of the heating component 12 are spaced apart in the radial direction, so that the heat of the heating component 12 can be weakened between the heat insulation component 14 and the heating component 12. A heat insulation cavity 141 is formed in the heat insulation component 14, and the heat insulation cavity 141 can be vacuumed or filled with air. The heat insulation cavity 141 is arranged around the heating component 12, so that the heat insulation cavity 141 can block the heat of the heating component 12 in the circumferential direction, prevent the heat from being conducted to other components, ensure the operational stability of the main body 100 of the device, and prevent the rod 1 from being too hot and burning the user, thus ensuring the safety and user experience.

[0075] In some embodiments, the device body 100 further includes a cover 13, which is movably mounted on the rod body 1. The rod body 1 has a placement port 11 communicating with the mounting cavity 4. The first substrate 43 is adapted to be placed in the heating cavity 44 through the placement port 11. The cover 13 is adapted to open or close the placement port 11, and the cover 13 is adapted to be magnetically connected to the rod body 1 when the placement port 11 is closed.

[0076] Specifically, the rod body 1 is provided with a placement port 11, which connects the mounting cavity 4 to the outside, allowing the user to place the first substrate 43 into the mounting cavity 4 through the placement port 11, so that the first substrate 43 can be replaced, and so on. Figures 1-2As shown, the main body 100 of the device is also provided with a cover 13, which is movably installed on the rod 1 and can be closed or opened at the placement port 11. When the user needs to replace or place the first substrate 43, the cover 13 can be operated to open the placement port 11. When the user inhales from the atomizing device 1000, the cover 13 can be operated to close the placement port 11. This makes the first substrate 43 replaceable, which is convenient for maintenance and flavor replacement. It also ensures the stability of the position of the first substrate 43 in the mounting cavity 4, so as to ensure the reliability of the main body 100 of the device.

[0077] In addition, such as Figure 8 As shown, the cover 13 is provided with an air inlet 131. When the cover 13 closes the placement port 11, the air inlet 131 can communicate with the mounting cavity 4, so that when the user inhales the atomizing device 1000, the gas can flow from the outside into the mounting cavity 4, flow through the first matrix 43, and then deliver the aroma of flue-cured tobacco to the user's mouth, ensuring the reliability of the delivery of the aroma of flue-cured tobacco, and thus ensuring the user's experience.

[0078] And such as Figure 1 and Figures 7-8 As shown, one end of the cover 13 is provided with a connecting part 136, and a rotating shaft or the like can be inserted into the connecting part 136, so that one end of the cover 13 can be rotatably connected to the rod 1 through the connecting part 136. The cover 13 is also suitable for magnetically connecting with the rod 1 when the placement port 11 is closed. That is, the other end of the cover 13 can be provided with a first magnetic attracting member 132, and the rod 1 is provided with a second magnetic attracting member. The first magnetic attracting member 132 and the second magnetic attracting member are correspondingly arranged. When the user operates the cover 13 to rotate the cover 13 to the placement port 11, the first magnetic attracting member 132 and the second magnetic attracting member can be magnetically connected to maintain the state of the cover 13 closing the placement port 11, thereby ensuring the reliability of the installation of the first substrate 43. In actual installation, one of the first magnetic attracting member 132 and the second magnetic attracting member can be constructed as a magnetic attracting member, and the other can be constructed as an iron material.

[0079] Furthermore, such as Figure 8 As shown, the cover 13 is provided with a handle 133, which is located at the other end of the cover 13 and protrudes outward, so that the user can rotate the cover 13 around the connecting part 136 by pressing the handle 133 to open the cover 13. This increases the point of action when the user presses the handle, and when the environment is dark, the user can distinguish the opening direction of the cover 13 by touch, improving the ease of use. The cover 13 also has a groove 134. When the cover 13 closes the placement opening 11, the groove 134 opens towards the mounting cavity 4 and is recessed in a direction away from the mounting cavity 4, so that one end of the first substrate 43 can be placed in the groove 134. In this way, the groove 134 can limit one end of the first substrate 43 and ensure the stability of the first substrate 43 in the mounting cavity 4.

[0080] In addition, such as Figure 8 As shown, the cover 13 is also provided with a mounting groove 135, which can be used to install the first magnetic component 132, making installation convenient and allowing the first magnetic component 132 to be detached from the cover 13, thus facilitating later maintenance.

[0081] In some embodiments, the device body 100 further includes an atomizing component receiving cavity 3 for accommodating the atomizing component 31. The device body 100 is provided with a conductive portion exposed in the atomizing component receiving cavity 3. The conductive portion is adapted to be electrically connected to the atomizing component 31 to supply power to the atomizing component 31.

[0082] Specifically, such as Figure 9 As shown, the main body 100 of the device is also provided with an atomizing component receiving cavity 3, which is used to install the atomizing component 31. A conductive part is also provided outside the main body 100, which is exposed outside the atomizing component receiving cavity 3. The main body 100 of the device is provided with a battery 21, which can be electrically connected to the atomizing component 31 through the conductive part. Thus, when the user inhales from the atomizing device 1000, the second substrate heating element 32 in the atomizing component 31 can atomize the second substrate in the atomizing component 31. The second substrate can be e-liquid, etc. The second substrate heating element 32 atomizes the second substrate to obtain atomized smoke, so that the main body 100 of the device can produce atomized smoke and also produce the aroma of roasted tobacco at the same time, to meet the different needs of users. In actual use, the first substrate 43 can be roasted while the second substrate is atomized, and the atomized smoke can be mixed with the aroma of roasted tobacco to enrich the taste and improve the user experience.

[0083] The present invention also proposes an atomizing device 1000.

[0084] According to an embodiment of the present invention, an atomizing device 1000 includes: a device body 100 and an atomizing component 31. The device body 100 is a device body 100 according to any one of the above claims. The device body 100 forms an atomizing component receiving cavity 3. The atomizing component receiving cavity 3 and the mounting cavity 4 are spaced apart. The atomizing component 31 is disposed in the atomizing component receiving cavity 3. The device body 100 supplies power to the atomizing component 31.

[0085] Specifically, such as Figure 9 As shown, the main body 100 of the device has an atomizing component receiving cavity 3 and an installation cavity 4, and the atomizing component receiving cavity 3 and the installation cavity 4 are spaced apart, that is, the atomizing component 31 and the first substrate 43 are spaced apart. This can prevent the atomized steam from causing the first substrate 43 to become damp and expand, thereby ensuring the stability of the aroma of the first substrate 43 and ensuring the smoke resistance when the airflow passes through the first substrate 43, so as to improve the user experience.

[0086] Furthermore, the main body 100 of the device is equipped with a switch button 231, a battery 21, a display screen 22, a first sensor 15 and a second sensor 16, etc. The battery 21 is used to supply power to the control module 23, the first sensor 15, the second sensor 16 and the display screen 22, etc. The switch button 231 is electrically connected to the battery 21 and can control the power supply status of the battery 21. The display screen 22 is used to display the battery level of the battery 21 or the flavor of the atomizing component 31, etc. The second sensor 16 is set in the mounting cavity 4 and can be constructed as an infrared sensor, etc. The second sensor 16 is used to detect the placement status of the first substrate 43 to prevent dry burning when the first substrate 43 is not placed in the mounting cavity 4, and to ensure the reliability of the main body 100 of the device.

[0087] In actual use, the atomizing component 31 is provided with an oil storage chamber and an atomizing chamber. The oil storage chamber can store the second substrate. When the user presses the switch button 231, the control module 23 controls the heating element 12 to heat the first substrate 43. After the heating element 12 continues to heat for 10s to 30s, the user draws air through the nozzle 200 of the atomizing device 1000. The airflow can trigger the first sensor 15. The first sensor 15 can be constructed as a pressure sensor. After a delay of 0.3s, the battery 21 supplies power to the second substrate heating element 32 in the atomizing component 31 through the conductive part. The second substrate in the oil storage chamber flows into the atomizing chamber. The second substrate heating element 32 in the atomizing component 31 can heat the second substrate to atomize it.

[0088] Furthermore, such as Figures 1-2 As shown, the atomizing device 1000 is also provided with a mouthpiece 200, and a mixing chamber 201 is formed inside the mouthpiece 200. The mixing chamber 201 is connected to the atomizing component receiving chamber 3 and the mounting chamber 4 respectively. After the second matrix is ​​atomized, it can flow into the mixing chamber 201 with the airflow, and the aroma of the flue-cured tobacco produced by the first matrix 43 can also flow into the mixing chamber 201 with the airflow, so that the atomized second matrix and the aroma of flue-cured tobacco can be mixed in the mixing chamber 201, thereby improving the complexity of the flavor and enhancing the user experience.

[0089] Furthermore, a filter element 202 and a cooling element 203 are also provided inside the mouthpiece 200. The aroma of flue-cured tobacco can be cooled at the cooling element 203 and then flow through the filter element 202 before flowing into the mixing chamber 201. The cooling element 203 can be constructed of ceramic material, which has a high specific heat capacity and can quickly exchange heat with the aroma of flue-cured tobacco to cool the aroma of flue-cured tobacco and ensure its palatability. In addition, the filter element 202 can filter impurities, tar, etc. in the aroma of flue-cured tobacco, improve the health of use, and enhance the user experience.

[0090] The atomizing device 1000 according to an embodiment of the present invention includes a device body 100. The device body 100 is configured such that the inner wall of the positioning member 41 and the inner wall of the heating member 12 are spaced apart, so that when the first substrate 43 is placed in the mounting cavity 4, the inner wall of the positioning member 41 can support the first substrate 43. This spaced-apart arrangement of the first substrate 43 and the heating member 12 avoids excessive local heating of the first substrate 43 by the heating member 12, ensuring heating uniformity and reducing suction resistance. At the same time, the airflow generated when the user inhales can flow between the heating member 12 and the first substrate 43, allowing the heating member 12 to perform non-penetrating three-dimensional heating of the first substrate 43 through both thermal radiation and thermal convection coupling, improving heating efficiency and enhancing the user experience. The device has a simple structure, low installation cost, better performance, and wider applicability.

[0091] In some embodiments, an annular guide channel 42 is formed within the positioning member 41, and the inner wall of the guide channel 42 defines the positioning portion 411.

[0092] Specifically, a ring-shaped guide channel 42 is formed inside the positioning member 41, and the guide channel 42 is connected to the heating chamber 44, so that the airflow in the guide channel 42 can flow into the heating chamber 44, or the airflow in the heating chamber 44 can flow into the guide channel 42. The first substrate 43 can be inserted into the guide channel 42, so that the guide channel 42 can guide and limit the first substrate 43, making it easier for the first substrate 43 to be placed in the mounting cavity 4, improving the convenience and accuracy of installation. The inner wall of the guide channel 42 can define the positioning part 411, so that the inner wall of the guide channel 42 can support the first substrate 43, so that the first substrate 43 is spaced apart from the heating member 12, ensuring the reliability of heating the first substrate 43.

[0093] When the first substrate 43 extends into the mounting cavity 4, at least a portion of the first substrate 43 can be placed in the heating cavity 44 of the heating element 12. There is an annular gap between the outer peripheral wall of the first substrate 43 and the inner peripheral wall of the heating element 12. When the airflow enters the annular gap, the heating element 12 can heat the airflow to form a high-temperature air curtain, and perform non-penetrating three-dimensional heating of the first substrate 43 in a way that couples thermal radiation and thermal convection, thereby improving heating efficiency and ensuring heating uniformity.

[0094] In actual setup, the first substrate 43 and the guide channel 42 are in clearance fit, and the clearance between the first substrate 43 and the guide channel 42 is smaller than the clearance between the first substrate 43 and the heating element 12. That is, the inner diameter of the heating element 12 is set to be larger than the inner diameter of the guide channel 42. This allows the positioning part 411 defined by the inner wall of the guide channel 42 to support and position the first substrate 43 while also allowing airflow to pass through the guide channel 42 into the heating chamber 44. This eliminates the need for additional structures and facilitates manufacturing.

[0095] In some other embodiments, the positioning part 411 is disposed on the guide channel 42 and protrudes from the guide channel 42.

[0096] Specifically, such as Figure 3 As shown, a positioning part 411 may be provided in the guide channel 42, and the positioning part 411 may be configured as a positioning protrusion, positioning block or positioning ring, etc. The positioning part 411 protrudes inward on the inner wall of the guide channel 42, so that the positioning part 411 can support the first substrate 43. At this time, the inner diameter of the heating element 12 and the guide channel 45 may be set to be equal, so that the inner peripheral wall of the heating element 12 is flush with the inner peripheral wall of the guide channel 45. In this way, the positioning part 411 can separate the outer peripheral wall of the first substrate 43 and the inner peripheral wall of the heating element 12 to avoid over-roasting of the first substrate 43 locally, and facilitate the flow of air between the first substrate 43 and the heating element 12, so that the airflow can carry the aroma of flue-cured tobacco to the user's oral cavity and ensure the user's experience.

[0097] In some embodiments, the axis of the guide channel 42 and the axis of the heating cavity 44 are aligned.

[0098] Specifically, such as Figure 1 and Figure 3 As shown, the positioning member 41 has a guide channel 42, and the first substrate 43 can be inserted into the guide channel 42, so that the positioning part 411 of the positioning member 41 can position the first substrate 43, ensuring the accuracy of the first substrate 43 in the mounting cavity 4. The axis of the guide channel 42 and the axis of the heating cavity 44 are coincident, that is, when the first substrate 43 is inserted into the guide channel 42 and the heating cavity 44, the distance between the outer peripheral wall of the first substrate 43 and the inner peripheral wall of the heating member 12 is the same in all circumferential directions, so that the heating effect of the heating member 12 on all parts of the outer peripheral wall of the first substrate 43 is the same. This can avoid the problem of excessive temperature in some parts of the first substrate 43 causing the aroma of the flue-cured tobacco to burn, so as to ensure the stability of the aroma of the first substrate 43 and improve the user experience.

[0099] In some embodiments, the positioning portion 411 includes at least three positioning protrusions, which are spaced apart circumferentially along the guide channel 42, and are used to support the positioning first substrate 43.

[0100] Specifically, the guide channel 42 is provided with a positioning part 411, and the positioning part 411 can be configured with at least three positioning protrusions, that is, the positioning protrusions can be three, four or five, etc. The at least three positioning protrusions are formed on the inner peripheral wall of the guide channel 42 and protrude into the guide channel 42. The at least three positioning protrusions are spaced apart along the circumference of the guide channel 42, so that the at least three positioning protrusions can support the first substrate 43 at at least three points in the circumference of the first substrate 43, thereby ensuring that the first substrate 43 is spaced apart from the inner peripheral wall of the heating element 12 at each point in the circumference, so as to ensure the heating effect of the first substrate 43 at each point in the circumference, improve the baking effect of the first substrate 43, and thus improve the user experience.

[0101] In some embodiments, the inner diameter of the heating element 12 is set to d1, and the outer diameter of the first substrate 43 is set to d2, satisfying: 0.2mm≤d1-d2≤0.7mm, that is, the size of the gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the first substrate 43 is set to be greater than or equal to 0.2mm and less than or equal to 0.7mm, ensuring that the heating element 12 can heat the first substrate 43 through both thermal radiation and thermal convection coupling, thereby improving the heating effect, so that the airflow entering the annular gap under suction negative pressure can stably form an air curtain, so as to balance suction resistance and heating uniformity and reduce the risk of local scorching. In addition, the length of the first substrate 43 is set to be greater than the distance between two adjacent positioning elements 41, so that both ends of the first substrate 43 can be supported and positioned by the positioning elements 41.
