Description

Technical Field

[0001] This invention relates to the field of atomizing device manufacturing technology, and in particular to a device body and an atomizing device having the device body. Background Technology

[0002] Atomizing devices offer a similar taste to traditional cigarettes while avoiding the tar and particulate matter. They can be used as a substitute for traditional cigarettes or for smoking cessation, offering convenience and health benefits. Existing atomizing devices can heat the cigarette and atomize e-liquid to produce smoke similar to traditional cigarettes, allowing users to enjoy both smoke and the aroma of roasted tobacco, enriching the flavor. Users can also replace the cigarettes to obtain different flavors, further enhancing the user experience. However, most existing atomizing devices use a "series coaxial" structure, where the vapor from the atomized e-liquid directly penetrates the cigarette. This can easily cause the cigarette to become damp and smelly, interfering with the original aroma and increasing draw resistance, negatively impacting the vaping experience. Furthermore, cigarette replacement is inconvenient, resulting in poor usability and room for improvement. Summary of the Invention

[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0027] 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.

[0028] Existing atomizing devices mostly adopt a "series coaxial" structure, which means that the vapor after atomization of the first matrix directly penetrates the second matrix. This can easily cause the second matrix to become damp and smelly, interfering with the original aroma and increasing the draw resistance, thus affecting the user's vaping experience. In addition, the second matrix is ​​inconvenient to replace, resulting in poor ease of use.

[0029] The following is for reference. Figures 1-10 The device body 100 described in the embodiment of the present invention can ensure that the atomizing component 31 and the second matrix 43 operate separately, thereby ensuring that the second matrix 43 is dry, so as to improve the draw resistance and aroma stability, ensure the user's inhalation experience, and facilitate the replacement of the second matrix 43, thereby improving the ease of use.

[0030] like Figures 1-10 As shown, the main body 100 of the device according to an embodiment of the present invention includes: a rod 1, a heating element 12, and a cover 13.

[0031] The rod body 1 has a first chamber 3 and a second chamber 4 spaced apart. The first chamber 3 is used to accommodate the atomizing component 31, and the second chamber 4 is used to accommodate the second substrate 43. The rod body 1 has a placement port 11 communicating with the second chamber 4. A heating element 12 is provided on the rod body 1 to heat the second substrate 43 in the second chamber 4. A cover 13 is movably installed on the rod body 1 to open or close the placement port 11. The cover 13 has an air intake area communicating with the second chamber 4. The air intake area is adapted to communicate between the second chamber 4 and the outside when the cover 13 closes the placement port 11.

[0032] 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.

[0033] 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 a first chamber 3 and a second chamber 4. The first chamber 3 is used to accommodate the atomizing component 31, and the second chamber 4 is used to accommodate the second matrix 43. The atomizing component 31 stores the first matrix, which can be set as e-liquid, etc. When the user inhales from the atomizing device 1000, the first matrix heating element 32 in the atomizing component 31 can atomize the first matrix to obtain atomized smoke.

[0034] The main body 100 of the device is equipped with a heating element 12, which is located in the second chamber 4. The heating element 12 can heat the second substrate 43, which can be a cigarette made of tobacco or other materials. When the user smokes, the heating element 12 can roast the second substrate 43, so that the second substrate 43 can produce a roasted tobacco aroma, thereby enriching the user's taste and improving the user experience. The first chamber 3 and the second chamber 4 are distributed separately, that is, the atomizing component 31 and the second substrate 43 are distributed separately, which can prevent the atomized steam from causing the second substrate 43 to become damp and expand, thereby ensuring the stability of the aroma of the second substrate 43 and ensuring the smoke resistance when the airflow passes through the second substrate 43, thus improving the user experience.

[0035] Furthermore, the rod body 1 is provided with a placement port 11, which connects the second chamber 4 to the outside, allowing the user to place the second substrate 43 into the second chamber 4 through the placement port 11, so that the second substrate 43 can be replaced. The device body 100 is also provided with a cover 13, which is movably installed on the rod body 1 and can close or open the placement port 11. When the user needs to replace or place the second 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, so that the second substrate 43 can be replaced, facilitating maintenance and flavor changes, and ensuring the stability of the position of the second substrate 43 in the second chamber 4, thereby ensuring the reliability of the device body 100.

[0036] In addition, the cover 13 is provided with an air intake area. When the cover 13 closes the placement port 11, the air intake area can connect the second chamber 4 and the outside when the cover 13 closes the placement port 11. This allows the gas to flow from the outside to the second chamber 4 through the air intake area when the user inhales from the atomizing device 1000, and then flow through the second matrix 43, thereby delivering the aroma of flue-cured tobacco to the user's mouth, ensuring the reliability of the aroma delivery and thus ensuring the user's experience.

[0037] According to the embodiment of the present invention, the main body 100 of the device is provided with a first chamber 3 and a second chamber 4 that are spaced apart. The atomizing component 31 is provided in the first chamber 3 and the second substrate 43 is provided in the second chamber 4. This ensures that the atomizing component 31 and the second substrate 43 can operate independently, so as to prevent the vapor after the atomization of the first substrate in the atomizing component 31 from penetrating the second substrate 43. This also prevents the second substrate 43 from getting damp, ensuring the stability of the aroma of the second substrate 43 and the stability of the suction resistance of the atomizing device 1000. In addition, the rod 1 is provided with a movable cover 13, which facilitates the placement and replacement of the second substrate 43, improves the convenience of use, improves the effect of use, and has a wider range of applications.

[0038] In some embodiments, the air intake area includes a plurality of spaced-apart air intake holes 131.

[0039] Specifically, such as Figure 1 and Figure 4As shown, the air intake area is provided with air intake holes 131, and there are multiple air intake holes 131. The multiple air intake holes 131 are distributed at intervals in the air intake area. The multiple air intake holes 131 are all connected between the second chamber 4 and the outside, so that the outside airflow can flow into the second chamber 4 through the multiple air intake holes 131, so as to carry the aroma of flue-cured tobacco of the second matrix 43 to the user's mouth. Setting multiple spaced air intake holes 131 can increase the airflow area, thereby improving the uniformity of airflow and flue-cured tobacco aroma mixing. In actual setting, the total opening area of ​​the multiple air intake holes 131 is constant, so as to ensure that the suction resistance is within a comfortable range while also ensuring the size of the airflow into the second chamber 4, thereby improving the user experience.

[0040] In some embodiments, one end of the cover 13 is rotatably connected to the device body 100, and the other end is provided with a first magnetic attractor 132. The rod 1 is provided with a second magnetic attractor. The first magnetic attractor 132 is adapted to be magnetically connected to the second magnetic attractor when the cover 13 is rotated to close the placement opening 11.

[0041] Specifically, the cover 13 is movably mounted on the rod 1, and as... Figure 1 and Figure 3 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 other end of the cover 13 is provided with a first magnetic suction member 132, and the rod 1 is provided with a second magnetic suction member. The first magnetic suction member 132 and the second magnetic suction member are correspondingly arranged. When the user operates the cover 13 to rotate the cover 13 to close the placement port 11, the first magnetic suction member 132 and the second magnetic suction 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 second substrate 43.

[0042] In addition, both the first magnetic 132 and the second magnetic 132 can be configured as multiple, that is, the first magnetic 132 can be configured as two, three or four, etc., and the second magnetic 132 can also be configured as two, three or four, etc. In this embodiment, both the first magnetic 132 and the second magnetic 132 are configured as two, which can improve the reliability of the magnetic connection between the first magnetic 132 and the second magnetic 132, thereby improving the reliability of the cover 13 closing the placement opening 11. In actual installation, one of the first magnetic 132 and the second magnetic 132 can be configured as a magnetic 132 and the other can be configured as an iron material.

[0043] In some embodiments, the other end of the cover 13 is provided with a protruding handle 133.

[0044] Specifically, 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, thus improving the ease of use.

[0045] And such as Figure 1 and 5 As shown, the cover 13 is located at the bottom of the rod body 1. One end of the cover 13 is rotatably connected to the middle of the bottom of the rod body 1, and the other end is integrated with the side wall of the rod body 1 when the cover 13 closes the placement opening 11, ensuring the integrity of the appearance. When the user opens the cover 13, the other end of the cover 13 rotates around the connecting part 136 downwards around the rod body 1, reducing the overall space occupied by the main body 100 of the device when the cover 13 is opened and closed, making it easier to use. The handle part 133 is formed on the side wall of the cover 13, making it easy for the user to operate. The end of the cover 13 away from the connecting part 136 is thicker in the length direction of the rod body 1, making it easier for the user to visually identify the cover 13, thereby improving the ease of use.

[0046] In some embodiments, the side of the cover 13 is provided with a groove 134 adapted to accommodate the second substrate 43, the air inlet area communicates with the groove 134, and the groove 134 is adapted to open toward the second chamber 4 when the cover 13 closes the placement port 11.

[0047] Specifically, such as Figure 1 and Figure 4 As shown, the cover 13 also has a groove 134. When the cover 13 closes the placement opening 11, the groove 134 opens towards the second chamber 4 and is recessed away from the second chamber 4, so that one end of the second substrate 43 can be placed in the groove 134. The groove 134 can limit one end of the second substrate 43 to ensure the stability of the second substrate 43 in the second chamber 4. The groove 134 is connected to the air intake area, so that the airflow entering through the air intake area can flow through one end of the second substrate 43 placed in the groove 134 and then flow into the second chamber 4, increasing the contact time between the airflow and the second substrate 43, increasing the mixing time of the airflow and the flue-cured tobacco aroma of the second substrate 43, thereby increasing the concentration of flue-cured tobacco aroma and improving the user experience.

[0048] In addition, such as Figure 4 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.

[0049] In some embodiments, the device body 100 further includes: a positioning component, which is installed in the second chamber 4 and forms a guide channel 45 extending through the second chamber 4; a heating element 12 is disposed around the guide channel 45 and forms a heating cavity 44; the inner peripheral wall of the heating element 12 is located outside the inner peripheral wall of the positioning component to define an annular air passage; the air inlet area is connected to the guide channel 45; and the annular air passage is connected between the guide channel 45 and the heating cavity 44.

[0050] Specifically, such as Figure 1 As shown, the main body 100 of the device is also provided with a positioning component. The positioning component can be installed in the second chamber 4 by snap-fit ​​or plug-in, and the positioning component forms a guide channel 45. The extension direction of the guide channel 45 is the same as the extension direction of the second chamber 4. When the second substrate 43 is placed in the second chamber 4 through the placement port 11, the second substrate 43 can be inserted into the guide channel 45, so that the guide channel 45 can limit the second substrate 43 in the radial direction to ensure the stability of the second substrate 43 installed in the second chamber 4.

[0051] Meanwhile, the heating element 12 is installed in the second chamber 4 and arranged around the guide channel 45. The heating element 12 forms a heating cavity 44. When the second substrate 43 extends into the second chamber 4, at least a portion of the second 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 second 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 second substrate 43 by coupling thermal radiation and thermal convection, thereby improving heating efficiency and ensuring heating uniformity.

[0052] Furthermore, the inner peripheral wall of the heating element 12 is located outside the inner peripheral wall of the positioning assembly to define an annular air passage. When the cover 13 closes the placement port 11, the air intake area can communicate with the guide channel 45. The annular air passage can communicate between the guide channel 45 and the heating chamber 44, so that the external airflow can flow through the air intake area into the guide channel 45, and the airflow in the guide channel 45 can flow through the annular air passage into the heating chamber 44.

[0053] When the second substrate 43 is inserted into the heating chamber 44, the cover 13 can close the placement port 11 to prevent the second substrate 43 from sliding out. The airflow in the annular air passage can flow into the annular gap between the outer peripheral wall of the second substrate 43 and the inner peripheral wall of the heating element 12. The minimum inner diameter of the positioning component is set to be smaller than the minimum inner diameter of the heating element 12 so that the positioning component can limit the second substrate 43 while the airflow can flow into the annular air passage between the heating element 12 and the second substrate 43. This ensures the reliability of the airflow. The airflow with a lower external temperature can undergo preliminary heat exchange at the annular air passage, avoiding the lower temperature at the end of the second substrate 43, which would result in poor heating at the end of the second substrate 43 and ensure the uniformity of heating at all parts of the second substrate 43.

[0054] In actual setup, the second substrate 43 and the guide channel 45 are in clearance fit, and the clearance between the second substrate 43 and the guide channel 45 is smaller than the clearance between the second 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 45. This allows the positioning part 411 defined by the inner wall of the guide channel 45 to support and position the second substrate 43 while also allowing airflow to pass through the guide channel 45 into the heating chamber 44. This eliminates the need for additional structures and facilitates manufacturing.

[0055] In addition, the inner diameter of the heating element 12 is set to d1, and the outer diameter of the second substrate 43 is set to d2, and the following condition is met: 0.2mm≤d1-d2≤0.5mm. That is, the size of the gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the second substrate 43 is set to be greater than or equal to 0.2mm and less than or equal to 0.5mm, so as to ensure that the heating element 12 can heat the second substrate 43 through both thermal radiation and thermal convection coupling, thereby improving the heating effect.

[0056] In actual testing, when the heating element 12 and the second 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 second substrate 43 is about 0.15mm, the temperature distribution on the surface of the second 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 second substrate 43. If the second substrate 43 is slightly elliptical, local overheating is very likely to occur. In addition, the tolerance space between the heating element 12 and the second substrate 43 is small, and the friction when inserting or removing the second substrate 43 is extremely large, resulting in a poor user experience.

[0057] When the heating element 12 and the second 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 second substrate 43 is about 0.25mm, it can be seen from the temperature cloud map characteristics that the air curtain between the second 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 second substrate 43 in the heating cavity 44 can be ensured, so that the circumferential temperature gradient is small. The air curtain between the second substrate 43 and the heating element 12 not only conducts heat but also acts as a heat spreader, avoiding the second substrate 43 from scorching, while ensuring sufficient heating inside the second substrate 43, thus ensuring the baking effect of the second substrate 43.

[0058] When the heating element 12 and the second substrate 43 are in a loosely 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 second substrate 43 is about 0.35mm, it can be seen from the temperature cloud map that the surface temperature of the second 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 second 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 second substrate 43.

[0059] When the heating element 12 and the second substrate 43 are inefficiently operating, that is, when the single-sided gap between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the second substrate 43 is about 0.5mm, the temperature cloud map shows that a clear low-temperature zone surrounds the second substrate 43, which leads to a significant decrease in the heating effect on the second 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 second substrate 43 may still not reach the required baking temperature. Furthermore, due to the large gap, the positioning protrusion provides poor support for the second substrate 43, which can easily lead to the second substrate 43 becoming eccentric. This can result in localized scorching and localized low temperatures in the second substrate 43, resulting in poor baking performance and affecting the user experience.

[0060] In actual setup, the second substrate 43 and the guide channel 45 are in a clearance fit, which makes the second substrate 43 have a small sway within the heating element 12, and thus the gap value between the inner peripheral wall of the heating element 12 and the outer peripheral wall of the second substrate 43 has a small fluctuation.

[0061] Based on the above physical analysis, Table 1 below is a comparison table of the comprehensive efficiency of the four gap conditions:

[0062] 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 second 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 second substrate 43 can be set to 0.25 mm.

[0063] In addition, the second chamber 4 is also provided with a heat insulation component 14. The heat insulation component 14 is sleeved on the outside of the heating component 12 and is spaced apart from the heating component 12 in the radial direction. A heat insulation cavity is formed inside the heat insulation component 14. The heat insulation cavity can be evacuated or filled with air, thereby preventing the heat generated by the heating component 12 from being conducted to the rod body 1, thus ensuring that the user is not burned during use, improving the safety and user experience.

[0064] In some embodiments, the inner peripheral wall of the guide channel 45 is formed with an inwardly protruding positioning protrusion for positioning the second substrate 43.

[0065] Specifically, the inner peripheral wall of the guide channel 45 is provided with a positioning protrusion. The positioning protrusion protrudes into the guide channel 45. When the second substrate 43 passes through the guide channel 45, the positioning protrusion can support the second substrate 43, so that there is a gap between the outer peripheral wall of the second substrate 43 and the inner peripheral wall of the positioning component. At this time, the inner diameter of the heating element 12 and the guide channel 45 can 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. The positioning protrusion on the inner peripheral wall of the guide channel 45 also creates a gap between the outer peripheral wall of the second substrate 43 and the inner peripheral wall of the heating element 12, so that the airflow can flow between the outer peripheral wall of the second substrate 43 and the inner peripheral wall of the heating element 12. Thus, the second substrate 43 can be heated in a non-penetrating three-dimensional manner through the coupling of thermal radiation and thermal convection, ensuring the heating effect.

[0066] In some embodiments, at least three positioning protrusions are provided, and the at least three positioning protrusions are distributed circumferentially spaced apart.

[0067] Specifically, at least three positioning protrusions are provided on the inner peripheral wall of the guide channel 45, and the at least three positioning protrusions are spaced apart along the circumference. That is, the positioning protrusions can be set to three, four or five, etc. The multiple positioning protrusions can support the second substrate 43 at various points along the circumference, so that the second substrate 43 is spaced apart from the inner peripheral wall of the heating element 12 at various points along the circumference, so as to ensure the heating effect of the second substrate 43 at various points along the circumference, improve the baking effect of the second substrate 43, and thus improve the user experience.

[0068] In some embodiments, the axis of the guide channel 45 and the axis of the heating cavity 44 are aligned.

[0069] Specifically, the positioning component forms a guide channel 45, and the second substrate 43 can be inserted into the guide channel 45, so that the positioning component can position the second substrate 43, ensuring the accuracy of the placement of the second substrate 43 in the second chamber 4. Moreover, the axis of the guide channel 45 and the axis of the heating chamber 44 are coincident, that is, when the second substrate 43 is inserted into the guide channel 45 and the heating chamber 44, the distance between the outer peripheral wall of the second substrate 43 and the inner peripheral wall of the heating element 12 is the same in all circumferential directions, so that the heating effect of the heating element 12 on all parts of the outer peripheral wall of the second substrate 43 is the same. This can avoid the problem of excessive temperature in some parts of the second substrate 43 causing the aroma of the flue-cured tobacco to burn, so as to ensure the stability of the aroma of the second substrate 43 and improve the user experience.

[0070] 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 on 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 second chamber 4.

[0071] Specifically, the heating element 12 is installed inside the second chamber 4, and as follows: Figure 7 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 second 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 distributed at intervals along the extension direction of the second chamber 4 on the outer peripheral wall of the heat-conducting element 123. 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 second substrate 43 located in the heat-conducting element 123, so as to improve the heating uniformity of the second substrate 43 and thus improve the baking effect.

[0072] In some embodiments, the main body 100 of the device further includes a control module 23, which is electrically connected to a plurality of heating elements 121 to control the heating amount of each heating element 121.

[0073] 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 7As 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. This allows for uniform heating of the heat-conducting element 123 along the axial direction, ensuring uniform heating of the second substrate 43. Furthermore, the control module 23 can individually control the heat of each heating element 121 via the wiring harness 232, allowing users to select the baking method of the second substrate 43 according to their preferences, thereby obtaining different baking aromas to meet different user needs.

[0074] 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 second 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 second 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.

[0075] In some embodiments, the positioning component includes a first positioning element 41 and a second positioning element 42, which are spaced apart along the extension direction of the second chamber 4.

[0076] Specifically, the positioning component forms a guide channel 45, and the second substrate 43 can be inserted into the guide channel 45, and as... Figure 1 As shown, the positioning component is provided with a first positioning element 41 and a second positioning element 42. The first positioning element 41 and the second positioning element 42 are spaced apart along the extension direction of the second chamber 4. In actual installation, the first positioning element 41 and the second positioning element 42 are respectively located at the air inlet end and the air outlet end of the second chamber 4. That is, the first positioning element 41 is located near the placement port 11, and the second positioning element 42 is located near the air outlet end, so that the two ends of the second substrate 43 can be inserted into the guide channel 45 of the first positioning element 41 and the guide channel 45 of the second positioning element 42, so that the first positioning element 41 and the second positioning element 42 can support the two ends of the second substrate 43 respectively, ensuring the stability of the installation position of the second substrate 43 in the second chamber 4.

[0077] In some embodiments, the heating element 12 is located between the first positioning element 41 and the second positioning element 42, and both ends of the heating element 12 are respectively engaged with the first positioning element 41 and the second positioning element 42.

[0078] Specifically, the first positioning element 41, the second positioning element 42, and the heating element 12 are all installed in the second chamber 4, and the heating element 12 is located between the first positioning element 41 and the second positioning element 42. The two ends of the heating element 12 are respectively engaged with the first positioning element 41 and the second positioning element 42. In actual installation, the two ends of the heating element 12 are respectively connected to the first positioning element 41 and the second positioning element 42 by means of plugging, so that the guide channel 45 is connected to the interior of the heating element 12, so that the second substrate 43 can be inserted into the guide channel 45 of the first positioning element 41 through the placement port 11, and then extend into the heating element 12, so that the heating element 12 can be inserted into the guide channel 45 of the second positioning element 42. Thus, the first positioning element 41 and the second positioning element 42 can support the second substrate 43, while the heating element 12 can heat the middle part of the second substrate 43, ensuring the stability of the relative position of the heating element 12 and the second substrate 43, so as to ensure the reliability of heating the second substrate 43.

[0079] In some embodiments, the main body 100 of the device further includes a sealing gasket 15, which is disposed in the first chamber 3 and adapted to cooperate with the atomizing component 31. A leak-proof groove 151 is formed on the side of the sealing gasket 15 facing the atomizing component 31. The rod body 1 is provided with an atomizing air inlet 16. The sealing gasket 15 is provided with a clearance hole 152 that connects the atomizing air inlet 16 and the first chamber 3. The leak-proof groove 151 and the clearance hole 152 are staggered.

[0080] Specifically, such as Figure 1 As shown, the main body 100 of the device is also provided with a sealing gasket 15. The sealing gasket 15 can be made of silicone or other materials and is disposed in the first chamber 3. The atomizing component 31 is also disposed in the first chamber 3. The sealing gasket 15 can seal with the atomizing component 31 to prevent the atomized gas in the atomizing component 31 from seeping into other parts of the main body 100 of the device, thus ensuring the operational stability of the internal structure of the main body 100. The main body 100 of the device is provided with an atomizing air inlet 16, through which airflow can enter the rod body 1. The sealing gasket 15 is provided with a clearance hole 152, which can be connected between the atomizing air inlet 16 and the first chamber 3, thereby allowing airflow to enter the first chamber 3 through the atomizing air inlet 16 and the clearance hole 152, so as to flow towards the atomizing component 31, allowing the first substrate to pass through the atomizing component 31 as if... Figure 1 The first substrate heating element 32 shown can be atomized and flow into the user's oral cavity with the airflow.

[0081] Furthermore, the sealing gasket 15 has a leak-proof groove 151, which is open to the atomizing component 31. The leak-proof groove 151 is staggered from the clearance hole 152. The atomized gas will produce liquids such as water vapor. The opening size of the leak-proof groove 151 is small, and the liquid can be temporarily stored in the leak-proof groove 151 by surface tension, which prevents the liquid from flowing back to other parts of the device body 100 and ensures the operational stability of the device body 100.

[0082] The present invention also proposes an atomizing device 1000.

[0083] 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 atomizing component 31 is disposed in a first chamber 3. The device body 100 supplies power to the atomizing component 31.

[0084] Specifically, such as Figure 1 As shown, the main body 100 of the device is equipped with a switch button 231, a battery 21, a display screen 22, a first sensor 17 and a second sensor 18, etc. The battery 21 is used to supply power to the control module 23, the first sensor 17, the second sensor 18 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 18 is located in the second chamber 4 and can be configured as an infrared sensor, etc. The second sensor 18 is used to detect the placement status of the second substrate 43 to prevent dry burning when the second substrate 43 is not placed in the second chamber 18, and to ensure the reliability of the main body 100 of the device.

[0085] 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 first substrate. When the user presses the switch button 231, the control module 23 controls the heating element 12 to heat the second 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 17. The first sensor 17 can be constructed as a pressure sensor. After a delay of 0.3s, the first substrate heating element 32 in the atomizing component 31 is activated. The first substrate in the oil storage chamber flows into the atomizing chamber. The first substrate heating element 32 in the atomizing component 31 can heat the first substrate to atomize it.

[0086] Furthermore, such as Figure 1 and Figure 9As 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 first chamber 3 and the second chamber 4 respectively. After the first substrate is atomized, it can flow into the mixing chamber 201 with the airflow, and the aroma of the flue-cured tobacco produced by the second substrate 43 can also flow into the mixing chamber 201 with the airflow, so that the atomized first substrate 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.

[0087] 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.

[0088] According to an embodiment of the present invention, the atomizing device 1000 includes a device body 100, which is provided with a first chamber 3 and a second chamber 4 spaced apart. An atomizing component 31 is provided in the first chamber 3, and a second substrate 43 is provided in the second chamber 4. This ensures that the atomizing component 31 and the second substrate 43 operate independently, thereby preventing the vapor from the atomized first substrate in the atomizing component 31 from penetrating the second substrate 43. This also prevents the second substrate 43 from getting damp, ensuring the stability of the aroma of the second substrate 43 and the stability of the suction resistance of the atomizing device 1000. In addition, the rod 1 is provided with a movable cover 13, which facilitates the placement and replacement of the second substrate 43, improving ease of use, better performance, and wider applicability.
