[0037] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.
[0038] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0039] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0040] The heating component in this application is used to heat and atomize the aerosol generating rod to produce an aerosol. The heating component can be installed in a matching atomization device. One end of the aerosol generating rod is an air inlet, and the other end is a suction end. The aerosol generating rod contains an atomizing matrix. When the user performs a suction action through the suction end, the gas from the air inlet is drawn into the aerosol generating rod, and the aerosol generated in the aerosol generating rod flows to the suction end under negative pressure.
[0041] The heating assembly utilizes a heat exchange core and heating element within a heat-conducting pipe. The heat generated by the heating element heats the heat exchange core and heat-conducting pipe. The heat exchange core has multiple through-holes. When the aerosol generating rod is inserted into the heat-conducting pipe, a suction action drives airflow through the vents of the heat exchange core, where it is heated to form a hot airflow that heats the aerosol generating rod. The heating element has at least two heating sections, and during use, one section can be heated individually or both sections can be heated simultaneously as needed. This allows for adjustment of the heat output, supplying the appropriate amount of heat to the aerosol generating rod at different stages of the suction process to meet its atomization requirements, ensuring precise heating and preventing overheating or scorching.
[0042] The following are some embodiments of the heating components and atomizing devices provided in this application, with reference to the accompanying drawings.
[0043] A heating assembly 100 is provided in an embodiment of the first aspect of this application. For example... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the heating assembly 100 includes a heat pipe 11, a heat exchange core 12, and a heating element 13. The heat pipe 11 is a through structure used to accommodate the heat exchange core 12, the heating element 13, and the aerosol generating rod; in a first direction, the heat pipe 11 has an insertion port 111 and an air inlet 112 arranged opposite to each other. The heat exchange core 12 is disposed inside the heat pipe 11 near the air inlet 112, and the heating element 13 is disposed on the outer wall of the heat exchange core 12. The heating element 13 can be electrically connected to the power supply assembly to generate heat when energized, thereby supplying heat to the heat exchange core 12 and the heat pipe 11; the heat exchange core 12 has a plurality of vent holes 121 extending along the first direction, and the gas flowing through the vent holes 121 can be heated to form a hot airflow. When the aerosol generating rod is inserted into the heat-conducting pipe 11 through the insertion port 111, the heating element 13 heats up. After being heated, the heat-conducting pipe 11 can preheat the aerosol generating rod from the side. When the user performs a suction action, external airflow can flow into the heat-conducting pipe 11 through the air inlet 112 under negative pressure, and pass through multiple vent holes 121 of the heat exchange core 12 to form a hot airflow, which then enters the interior of the aerosol generating rod to achieve heating by the hot airflow. The heating element 13 includes at least two heating parts 130. By energizing different heating parts 130, one heating part 130 can heat up individually or at least two heating parts 130 can heat up together, so as to make appropriate adjustments to the heat supply according to the changes in the heat demand of the aerosol generating rod at different stages.
[0044] It is understandable that, under normal circumstances, the heat required in the early stage of heating the aerosol generating rod (such as the first suction action or the first few suction actions) is relatively large, while the heat required in the middle and later stages of heating the aerosol generating rod will decrease. If the amount of heat supplied is the same in different stages, the amount of heat supplied in the middle and later stages of heating is likely to exceed the actual demand, which may cause the aerosol generating rod to be overheated or scorched, affecting the user experience.
[0045] The heating component 100 in this application, through structural improvements and optimizations, provides a heating element 13 with at least two heating sections 130 on the outer wall of the heat exchange core 12. It can achieve simultaneous heating of at least two heating sections 130 or individual heating sections 130 heating individually to heat the heat exchange core 12 as a whole or locally. It can be adjusted according to the suction action at different stages during use to meet the heating requirements at different stages, thereby preventing the aerosol generating rod from being overheated or scorched due to excessive heating, which is beneficial to improving the user experience.
[0046] It should be noted that the specific shape and size of the heat pipe 11 can be set according to the shape and size of the aerosol generating rod and the specific assembly requirements, and the specific shape and size of the heat exchange core 12 can be adapted to the heat pipe 11.
[0047] Furthermore, such as Figure 3, Figure 5 and Figure 6 As shown, the heat exchange core 12 has at least two heating areas, and the positions of at least two heating parts 130 of the heating element 13 correspond to different heating areas on the heat exchange core 12, that is, each heating part 130 corresponds to one of the heating areas on the heat exchange core 12. When the heating part 130 is energized, the corresponding heating area on the heat exchange core 12 can be heated, thereby achieving segmented and regional heating. The heating part 130 has electrodes for connecting to the power supply component, so that when applied in an atomizing device, it can be electrically connected to the power supply component through the electrodes, thereby supplying power to different heating parts 130 through the power supply component.
[0048] It should be noted that in practical applications, the energizing state of different heating elements 130 can be controlled by the corresponding control unit in the power supply assembly, so that the energizing state of the heating element 130 is adapted to the suction action at different stages, thereby achieving localized or overall heating of the heat exchange core 12. The heating element 130 can be, for example, Figure 7 The heating element structure shown can also be a heating mesh structure. Preferably, the heating element 130 adopts a flexible structure, which is convenient for assembly and can be closely attached to the surface of the heat exchange core 12.
[0049] In further embodiments of this application, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in a specific example of the heating element 13, the heating element 13 includes a first heating structure 1311, a first head electrode 1312, a first tail electrode 1313, and at least one first common electrode 1314. The first heating structure 1311 is arranged circumferentially along the heat exchange core 12, but is not closed in the circumferential direction, i.e., one end is the head end and the other end is the tail end; the first head electrode 1312 is connected to the head end of the first heating structure 1311 in the circumferential direction, the first tail electrode 1313 is connected to the tail end of the first heating structure 1311 in the circumferential direction, and the first common electrode 1314 is connected to the area on the first heating structure 1311 located between the first head electrode 1312 and the first tail electrode 1313. Figure 7 and Figure 8For example, there is one first common electrode 1314, and the first heating structure 1311 is divided into two heating parts 130 on the left and right sides in the circumferential direction by the first common electrode 1314. When any two electrodes are energized at the same time, the corresponding heating parts 130 will heat up. When the first common electrode 1314 and the first head electrode 1312 are energized at the same time and the first tail electrode 1313 is not energized, the heating part 130 on the left side is energized and heats up. When the first common electrode 1314 and the first tail electrode 1313 are energized at the same time and the first head electrode 1312 is not energized, the heating part 130 on the right side is energized and heats up. When the first head electrode 1312 and the first tail electrode 1313 are energized at the same time and the first common electrode 1314 is not energized, both heating parts 130 are energized and heat up at the same time, that is, the first heating structure 1311 heats up as a whole at this time. The configuration in this embodiment allows for segmented and zoned heating of different areas of the heat exchange core 12 in the circumferential direction, enabling localized or overall heating as needed.
[0050] It should be noted that when at least two first common electrodes 1314 are provided, the at least two first common electrodes 1314 can be arranged circumferentially. At this time, the number of heating elements 130 is greater than two. When any two electrodes are energized at the same time, the heating element 130 located between the two electrodes can be energized and heated. However, the principle of energizing and heating is similar to that in the above example, and will not be repeated here.
[0051] Of course, the specific arrangement of the heating element 13 is not limited to the above example. In practical applications, at least two heating elements 130 can also be arranged in the first direction, such as... Figure 9 In the example, the heating element 13 includes two second heating structures 1321, which are spaced apart in a first direction. Each second heating structure 1321 is arranged circumferentially along the heat exchange core 12, but is not a closed structure in the circumferential direction, thus forming a heating part 130 for each second heating structure 1321, i.e., forming two heating parts 130, one above the other, in the first direction. The heating element 13 also includes two second end electrodes 1322 and one second common electrode 1323. Each end of the second heating structure 1321 is connected to a corresponding second end electrode 1322. The two second end electrodes 1322 can be staggered in the circumferential direction to avoid mutual contact. The second common electrode 1323 is connected to the ends of both second heating structures 1321. In use, as... Figure 9In the example, when the second common electrode 1323 and the upper second first electrode 1322 are energized simultaneously, while the lower second first electrode 1322 is not energized, the upper heating part 130 is energized and heats up; when the second common electrode 1323 and the lower second first electrode 1322 are energized, while the upper second first electrode 1322 is not energized, the lower heating part 130 is energized and heats up; when the second common electrode 1323 and the two second first electrodes 1322 are energized simultaneously, the upper and lower heating parts 130 are energized and heat up simultaneously.
[0052] The above configuration enables segmented and regional heating of the heat exchange core 12 in the first direction, allowing for localized or overall heating as needed. When any heating element 130 heats up individually, it can cover most of the circumferential area of the heat exchange core 12, resulting in relatively uniform heating and further reducing the possibility of localized overheating.
[0053] It should be noted that in practical applications, the number of the second heating structure 1321 in the above example can also be greater than two, to form more heating parts 130. The specific principle of heating by electricity is similar to that in the above example, and will not be repeated here.
[0054] In addition, it should be emphasized that the above are only examples of different structural forms of a single heating element 13. In practical applications, multiple independent heating elements 13 can also be set at the same time. Multiple heating elements 13 can adopt any of the above structural forms or a combination of the above two structural forms. The appropriate structural form can be selected according to the actual heating needs, which will not be elaborated here.
[0055] In further embodiments of this application, such as Figure 3 , Figure 10 and Figure 11 As shown, the heating assembly 100 also includes an insulating sleeve 14. The insulating sleeve 14 is disposed inside the heat-conducting pipe 11 and sleeved on the outside of the heat exchange core 12, i.e., the insulating sleeve 14 is located between the heat exchange core 12 and the heat-conducting pipe 11; the inner wall of the insulating sleeve 14 abuts against the heating element 13, pressing the heating element 13 tightly against the outer wall of the heat exchange core 12, thereby laterally fixing the heating element 13 and isolating it from the heat-conducting pipe 11, thus providing insulation. A first clearance notch 141 or clearance groove 142 is provided on the insulating sleeve 14 at a position corresponding to the electrode of the heating element 13, for example... Figure 11In the example shown, the heating element 13 has a first head electrode 1312, a first tail electrode 1313, and a first common electrode 1314 spaced apart in the circumferential direction. A first clearance notch 141 is provided on the insulating sleeve 14 in the area corresponding to the first head electrode 1312 and the first tail electrode 1313. The first head electrode 1312 and the first tail electrode 1313 are located in the first clearance notch 141 and extend along a first direction. A clearance groove 142 extending along the first direction is provided on the inner wall of the insulating sleeve 14 in the area corresponding to the first common electrode 1314. At least a portion of the first common electrode 1314 is located in the clearance groove 142 and extends along the first direction. By providing the first clearance notch 141 and the clearance groove 142, installation space is reserved for the electrodes, while simultaneously ensuring that the inner wall surface of the heating element 13 is in close contact with the surface of the heat exchange core 12. Correspondingly, a second clearance notch 117 can be provided on the heat pipe 11 at the position corresponding to the first clearance notch 141 to prevent the heat pipe 11 from contacting the electrode.
[0056] Furthermore, such as Figure 10 and Figure 11 In the example shown, one end of the heat pipe 11 with an air inlet has a support structure 113. During assembly, after the heat exchange core 12, heating element 13, and insulating sleeve 14 are all installed into the heat pipe 11, the support structure 113 can be bent so that it extends into the inside of the heat pipe 11. Figure 1 and Figure 4 The state shown is such that the support structure 113 abuts against the insulating sleeve 14 and the heat exchange core 12 in a first direction to provide support for the insulating sleeve 14 and the heat exchange core 12.
[0057] Furthermore, such as Figure 3 , Figure 5 as well as Figure 10 , Figure 11 In the example, the outer wall of the insulating sleeve 14 has a first protrusion structure 143. In a first direction, the first protrusion structure 143 is located at one end away from the insertion port 111 of the heat pipe 11. The first protrusion structure 143 extends outward from the insulating sleeve 14, and a positioning groove 145 is provided on the first protrusion structure 143 at a position corresponding to the support structure of the heat pipe 11. The first protrusion structure 143 abuts against one end of the heat pipe 11 where the air inlet 112 is provided, and the support structure of the heat pipe 11 passes through the corresponding positioning groove 145 and extends to the inner side of the heat pipe 11, thereby realizing the connection and fixation between the heat pipe 11 and the insulating sleeve 14. At the same time, the positioning groove 145 can play a positioning role during the assembly process, which is conducive to quick alignment operation and improves assembly efficiency.
[0058] Furthermore, such as Figure 3 , Figure 10 and Figure 11 In the example, the inner wall of the insulating sleeve 14 has a second protrusion structure 144. The second protrusion structure 144 extends inward toward the inner side of the insulating sleeve 14, and in a first direction, the second protrusion structure 144 abuts against one end of the heat exchange core 12 toward the insertion port 111 of the heat guide pipe 11, so as to fix and axially limit the heat exchange core 12. The shape and size of the second protrusion structure 144 are adapted to the heat exchange core 12 so as to be misaligned with the vent hole 121 on the heat exchange core 12 to avoid blocking the vent hole 121.
[0059] It should be noted that the first protrusion structure 143 and the second protrusion structure 144 mentioned above can both adopt the following... Figure 10 The structure shown is continuous along the circumference, but of course, a discontinuous structure along the circumference can also be used.
[0060] In further embodiments of this application, such as Figure 6 and Figure 12 As shown, the multiple vents 121 of the heat exchange core 12 are arranged in an array. For example, the multiple vents 121 are arranged in a ring array with the center line of the heat exchange core 12 as the axis, or the multiple vents 121 can also be arranged in a matrix. Figure 12 In the example, the heat exchange core 12 adopts a cylindrical structure, and the vent holes 121 adopt a multi-layer ring array, which can be adapted to the cylindrical heat exchange core 12, making full use of the limited space to set a larger number of vent holes 121, and the vent holes 121 are arranged relatively evenly.
[0061] In further embodiments of this application, such as Figure 10 and Figure 11 As shown, the outer wall of the heat exchange core 12 has a first groove 122, which extends circumferentially to reserve installation space for the heating element 13. The heating element 13 is disposed in the first groove 122, and in the first direction, both ends of the heating element 13 abut against the corresponding sidewalls of the first groove 122, so that the sidewalls of the first groove 122 limit the heating element 13 in the first direction, preventing the heating element 13 from moving relative to the heat exchange core 12, and making the connection of the heating element 13 more secure.
[0062] In further embodiments of this application, such as Figure 2 , Figure 3 and Figure 11As shown, the heat pipe 11 includes a heat exchange section 114 and an insertion section 115. In a first direction, the heat pipe 11 communicates with the insertion section 115. The heat exchange section 114 is located near the air inlet 112, and the insertion section 115 is located near the insertion port 111. The heat exchange core 12 and the heating element 13 are disposed within the heat exchange section 114 of the heat pipe 11, while the insertion section 115 is used to accommodate the aerosol generating rod. The inner wall of the insertion section 115, near the heat exchange section 114, has a second groove 1151. The second groove 1151 extends radially outward along the heat pipe 11 and circumferentially, so that the inner diameter of the area in the insertion section 115 where the second groove 1151 is provided is larger than the inner diameter of the area where the second groove 1151 is not provided, forming a stepped structure. When the aerosol generating rod is inserted into the insertion section 115 of the heat-conducting pipe 11 through the insertion port 111, the radial distance between the area where the second groove 1151 is provided in the insertion section 115 and the aerosol generating rod is greater than the radial distance of other areas. This can reduce the lateral heating amount of the aerosol generating rod by the second groove 1151, so that more heat in the heat-conducting pipe 11 is conducted to the area where the second groove 1151 is not provided (i.e., the area away from the heat exchange section 114 in the first direction). This can further reduce the possibility of over-baking or scorching of the part of the aerosol generating rod near the heat exchange core 12.
[0063] It is understandable that, since the heating element 13 is located on the outer wall of the heat exchange core 12, and the heat generated by the hot airflow from the vent 121 of the heat exchange core 12 is greater than the heat of the side wall of the heat pipe 11, after the aerosol generating rod is inserted into the insertion section 115 of the heat pipe 11, the area closer to the heat exchange core 12 receives more heat. For example, the air inlet end of the aerosol generating rod is closest to the heat exchange core 12 and is heated by the hot airflow while also receiving heat from the side wall of the insertion section 115, which can easily lead to overheating or scorching. By setting a second groove 1151 in the area of the insertion section 115 near the heat exchange section 114 (i.e., the area near the air inlet end of the aerosol generating rod), the lateral heating in this area can be reduced, and the lateral heating can be conducted to the area away from the heat exchange core 12. This allows the heat to be conducted more evenly to different areas of the aerosol generating rod, thereby balancing the temperature difference and preventing excessive heating in local areas from causing overheating or scorching.
[0064] It should be noted that in practical applications, the second groove 1151 can be processed in different ways, for example... Figure 3In the example shown, the area of the insertion section 115 of the heat pipe 11 near the heat exchange section 114 expands from the inside out to form a second groove 1151 on the inner sidewall, so that the overall wall thickness of the heat pipe 11 remains consistent. Furthermore, when an insulating sleeve 14 is provided inside the heat pipe 11 of the heating assembly 100, the aerosol generating rod, after being inserted into the insertion section 115 of the heat pipe 11, can directly abut against the end of the insulating sleeve 14, or it can abut against the stepped structure formed by the second groove 1151.
[0065] An embodiment of the second aspect of this application provides an atomizing device 200, such as... Figure 13 and Figure 14 As shown, the atomizing device 200 includes a housing 21, a power supply component 22, and a heating component 100 as described in any of the embodiments of the first aspect. Both the power supply component 22 and the heating component 100 are disposed within the housing 21, and the power supply component 22 is electrically connected to the heating element 13 of the heating component 100 to supply power to the heating element 13. An assembly port 211 is provided on the housing 21, and the insertion port 111 of the heating component 100 is correspondingly provided with the assembly port 211. In use, as... Figure 15 In the example, the aerosol generating rod 31 can be inserted through the assembly port 211 and into the heat conduction pipe 11 of the heating assembly 100 to form an assembly with the atomizing device 200. The aerosol generating rod 31 is then heated by the hot air flow generated by the heating assembly 100 and the heat conduction pipe 11, so that the atomizing matrix in the aerosol generating rod 31 is heated and atomized to generate aerosol.
[0066] Among them, such as Figure 3 and Figure 6 In the example, the heating element 13 has at least two heating parts 130. During use, different heating parts 130 can be energized to make them heat up. For example, a single heating part 130 can be heated individually or at least two heating parts 130 can be heated together. This achieves local or overall heating of the heat exchange core 12, so that the heating amount can be adjusted according to the heat demand of the aerosol generating rod 31 at different stages of the suction action, so that the heating amount is adapted to the actual demand and prevents the aerosol generating rod 31 from being over-baked or scorched in some areas, which would affect the user experience.
[0067] The atomizing device 200 in this embodiment can effectively alleviate the above problems and realize dynamic adjustment of heating amount, thereby achieving precise heating of aerosol generating rod 31 and effectively preventing over-baking or scorching.
[0068] Furthermore, the atomizing device 200 in this embodiment has all the beneficial effects of the heating component 100 in any of the above embodiments, which will not be repeated here.
[0069] It should be noted that the aerosol generating rod 31 and the atomizing device 200 can be independent structures, which are assembled by the user during use.
[0070] Furthermore, such as Figure 14 and Figure 15 In the example shown, depending on actual usage needs, a corresponding atomizing chamber and an electrical cavity can also be provided within the housing 21. The heating component 100 is disposed within the atomizing chamber, and the power supply component 22 is disposed within the electrical cavity, so that the power supply component 22 is isolated from the heating component 100. Specifically, the power supply component 22 may include a battery and a corresponding control unit, so as to control the power supply state of different heating parts 130 of the heating element 13 through the control unit.
[0071] In further embodiments of this application, such as Figures 13 to 16 As shown, the atomizing device 200 also includes a support base 23, a pressure cap structure 24, and a contact element 25. The support base 23 has a mounting cavity 231 for mounting the heating assembly 100, which extends through both ends in a first direction; a support structure 232 for supporting the heating assembly 100 is connected to the inner wall of the mounting cavity 231. Correspondingly, a third protrusion structure 116 protrudes outward from the outer wall of the end of the heat-conducting pipe 11 where the insertion port 111 is located. The heat-conducting pipe 11 is disposed in the mounting cavity 231 of the support base 23 along the first direction, and the third protrusion structure 116 abuts against the end of the support structure 232 facing the assembly port 211, so as to support the heating assembly 100 through the support structure 232.
[0072] The cap structure 24 has through-hole structures at both ends in the first direction and is located between the assembly port 211 and the support base 23. The cap structure 24 abuts against one end of the heat pipe 11 with the insertion port 111 to press the heat pipe 11 onto the support structure 232 and to connect the cap structure 24 with the heat pipe 11. The contact element 25 is made of a flexible material and can produce a certain degree of elastic deformation. The contact element 25 is located inside the cap structure 24, and both ends of the contact element 25 are through-hole in the first direction to form a nested form with the cap structure 24. Multiple fourth protrusion structures 251 are provided on the inner sidewall of the contact element 25, and the multiple fourth protrusion structures 251 are spaced apart circumferentially. When the aerosol generating rod 31 is inserted into the heat pipe 11, such as Figure 15In the example shown, the aerosol generating rod 31 passes through both the pressure cap structure 24 and the contact member 25. Multiple fourth protrusions 251 on the inner side of the contact member 25 abut against the outer wall of the aerosol generating rod 31, thus limiting and fixing the aerosol generating rod 31. This prevents the aerosol generating rod 31 from shaking and also prevents axial movement of the aerosol generating rod 31 through contact friction, improving the assembly stability of the aerosol generating rod 31. Furthermore, in the circumferential direction, the gap between adjacent fourth protrusions 251 allows airflow to pass through, maintaining communication between the pressure cap structure 24 and the outside environment for easy air intake.
[0073] Among them, such as Figure 14 In the example, the sidewall of the gland structure 24 has a through first vent 241, allowing the intake airflow to pass through the first vent 241 into the mounting cavity 231 of the support 23. Additionally, as... Figure 16 In the example, when the support structure 232 adopts a circumferentially continuous structure, one or more second air passages 235 can be provided on the support structure 232 so that the airflow passing through the first air passage 241 can flow through the second air passage 235 to the air inlet 112 of the heat pipe 11, and then enter the air vent 121 of the heat exchange core 12 from the air inlet 112 to form a hot airflow.
[0074] It should be noted that the third protrusion structure 116 can be a continuous structure extending circumferentially or a discontinuous structure in the circumferential direction; correspondingly, the support structure 232 can also be a continuous structure extending circumferentially or a discontinuous structure in the circumferential direction. In addition, the support structure 232 and the support base 23 can be integrally formed or separate structures connected by welding or other methods.
[0075] Furthermore, the gland structure 24 can be a one-piece structure or a separate structure. The contact element 25 can be, for example... Figure 14 The integrated structure shown in the figure means that the contact 25 is made of flexible material. Of course, it can also be set that the main body of the contact 25 is a rigid structure, with multiple flexible material fourth protrusions 251 fixedly connected to the inner side wall.
[0076] The following describes a specific example of the atomizing device 200 of this application with reference to the accompanying drawings.
[0077] like Figures 1 to 16 As shown, the atomizing device 200 includes a housing 21, a power supply component 22, a heating component 100, a support base 23, a pressure cap structure 24, and a contact element 25. The height direction of the housing 21 is the first direction.
[0078] like Figures 13 to 15As shown, the housing 21 has an assembly opening 211 at its top end in the first direction for inserting and assembling the aerosol generating rod 31. The housing 21 has an atomizing chamber and an electrical chamber. The power supply component 22 and the heating component 100 are both disposed inside the housing 21, with the power supply component 22 located in the electrical chamber and the heating component 100 located in the atomizing chamber.
[0079] like Figures 1 to 8 and Figure 10 , Figure 11 As shown, the heating assembly 100 includes a heat pipe 11, a heat exchange core 12, a heating element 13, and an insulating sleeve 14. The heat pipe 11 is a through cylindrical structure. In a first direction, the heat pipe 11 has an insertion port 111 and an air inlet 112 arranged opposite to each other, with the insertion port 111 facing the assembly port 211 of the housing 21. The heat pipe 11 includes a heat exchange section 114 and an insertion section 115 that communicate in the first direction. The heat exchange section 114 is located near the air inlet 112, and the insertion section 115 is located near the insertion port 111. The insertion section 115 is used to accommodate the aerosol generating rod 31. The heat exchange core 12 is disposed in the heat exchange section 114 of the heat pipe 11. The heat exchange core 12 specifically adopts a cylindrical structure and has multiple vent holes 121 that are through in the first direction. The multiple vent holes 121 are arranged in a multi-layer annular array with the center line of the heat exchange core 12 as the axis.
[0080] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the heating element 13 includes a first heating structure 1311, a first head electrode 1312, a first tail electrode 1313, and a common electrode. The first heating structure 1311 is a flexible heating element structure and is arranged circumferentially along the heat exchange core 12, but is not closed in the circumferential direction (e.g., the circumferential coverage angle is in the range of 330° to 350°). The first head electrode 1312 is connected to the head end of the first heating structure 1311 in the circumferential direction, and the first tail electrode 1313 is connected to the tail end of the first heating structure 1311 in the circumferential direction. The first common electrode 1314 is connected to the area of the first heating structure 1311 located between the first head electrode 1312 and the first tail electrode 1313. The first heating structure 1311 is divided into two symmetrical heating parts 130 in the circumferential direction by the first common electrode 1314. Figure 10 and Figure 11As shown, the outer sidewall of the heat exchange core 12 has a first groove 122, which extends circumferentially. The first heating structure 1311 is disposed in the first groove 122, and in the first direction, the two ends of the first heating structure 1311 respectively abut against the sidewall of the first groove 122, so as to limit the heating element 13 in the first direction through the sidewall of the first groove 122. The first terminal electrode 1312, the first tail electrode 1313, and the first common electrode 1314 are all electrically connected to the power supply component 22. When the first common electrode 1314 and the first terminal electrode 1312 are energized simultaneously and the first tail electrode 1313 is not energized, the heating part 130 on the left side is energized and heats up. When the first common electrode 1314 and the first tail electrode 1313 are energized simultaneously and the first terminal electrode 1312 is not energized, the heating part 130 on the right side is energized and heats up. When the first terminal electrode 1312 and the first tail electrode 1313 are energized simultaneously and the first common electrode 1314 is not energized, both heating parts 130 are energized and heat up simultaneously.
[0081] like Figure 3 , Figure 10 and Figure 11 As shown, the insulating sleeve 14 is sleeved on the outside of the heat exchange core 12, that is, the insulating sleeve 14 is located between the heat exchange core 12 and the heat conduction pipe 11; the inner wall of the insulating sleeve 14 abuts against the heating element 13 and presses the heating element 13 tightly onto the outer wall of the heat exchange core 12 to fix the heating element 13 laterally, and at the same time isolate the heating element 13 from the heat conduction pipe 11, thus playing an insulating role. The insulating sleeve 14 has a first clearance notch 141 in the area corresponding to the first head electrode 1312 and the first tail electrode 1313. The first head electrode 1312 and the first tail electrode 1313 are located in the first clearance notch 141 and extend along the first direction. Correspondingly, the heat pipe 11 has a second clearance notch 117 in the position corresponding to the first clearance notch 141 to prevent the heat pipe 11 from contacting the electrodes. The inner sidewall of the insulating sleeve 14 has a clearance groove 142 in the area corresponding to the first common electrode 1314, which extends along the first direction. At least a part of the first common electrode 1314 is located in the clearance groove 142 and extends along the first direction.
[0082] The heat pipe 11 has an air inlet at one end, which has a support structure 113. During assembly, after the heat exchange core 12, heating element 13, and insulating sleeve 14 are all installed into the heat pipe 11, the support structure 113 is bent so that it extends into the inside of the heat pipe 11. Figure 1 and Figure 4 The configuration shown is such that the support structure 113 abuts against the insulating sleeve 14 and the heat exchange core 12 in a first direction to provide support for the insulating sleeve 14 and the heat exchange core 12. Figure 3 , Figure 5 as well as Figure 10 , Figure 11 In the example, the outer wall of the insulating sleeve 14 has a first protrusion structure 143. In a first direction, the first protrusion structure 143 is located at one end away from the insertion port 111 of the heat pipe 11. The first protrusion structure 143 extends outward from the insulating sleeve 14, and a positioning groove 145 is provided on the first protrusion structure 143 at a position corresponding to the support structure of the heat pipe 11. The first protrusion structure 143 abuts against one end of the heat pipe 11 where the air inlet 112 is provided, and the support structure of the heat pipe 11 passes through the corresponding positioning groove 145 and extends to the inner side of the heat pipe 11, thereby realizing the connection and fixation between the heat pipe 11 and the insulating sleeve 14. The inner wall of the insulating sleeve 14 has a second protrusion 144, which extends inward and abuts against the end of the heat exchange core 12 facing the insertion port 111 of the heat pipe 11 in a first direction. The second protrusion 144 is offset from the vent hole 121 on the heat exchange core 12 to avoid blocking the vent hole 121. The insulating sleeve 14 and the heat exchange core 12 are fixed by the support structure 113 and the second protrusion 144.
[0083] like Figure 2 , Figure 3 and Figure 11 As shown, the inner wall of the insertion section 115 of the heat pipe 11 has a second groove 1151 near the heat exchange section 114. The second groove 1151 grooves outward radially along the heat pipe 11 and extends circumferentially, so that the inner diameter of the area in the insertion section 115 where the second groove 1151 is provided is larger than the inner diameter of other areas, forming a stepped structure. When the aerosol generating rod 31 is inserted into the insertion section 115 of the heat pipe 11, the radial distance between the area in the insertion section 115 where the second groove 1151 is provided and the aerosol generating rod 31 is larger than the radial distance of other areas.
[0084] like Figures 13 to 16As shown, both the pressure cap structure 24 and the contact element 25 adopt a cylindrical structure to adapt to the aerosol generating rod 31. The support base 23 includes a support sleeve 233 and a support base 234; the support sleeve 233 has a mounting cavity 231, which is open at both ends in the first direction, and a support structure 232 is connected to the inner wall of the mounting cavity 231; the support base 234 is connected to the end of the support sleeve 233 away from the assembly port 211 and is fixedly connected to the housing 21. The heating component 100 is disposed in the mounting cavity 231, and the insertion port 111 of the heat conduction pipe 11 corresponds to the assembly port 211 of the housing 21; a third protrusion structure 116 is provided on the outer wall of the end of the heat conduction pipe 11 where the insertion port 111 is located, the third protrusion structure 116 protrudes outward, and the third protrusion structure 116 abuts against the support structure 232 in the mounting cavity 231.
[0085] like Figures 14 to 16 As shown, the pressure cap structure 24 and the contact element 25 are nested together. Both ends of the pressure cap structure 24 in the first direction are through structures, and the pressure cap structure 24 abuts against the end face of the heat pipe 11 with the insertion port 111. The contact element 25 is located inside the pressure cap structure 24 and is made of a flexible material capable of elastic deformation. The contact element 25 is through at both ends in the first direction, and multiple fourth protrusions 251 are provided on the inner wall of the contact element 25, with these protrusions spaced evenly in the circumferential direction. Multiple first vent holes 241 are spaced circumferentially on the inner wall of the pressure cap structure 24. Correspondingly, the support structure 232 is an annular structure, and multiple second vent holes 235 are spaced circumferentially on the support structure 232. Figure 15 In the example, when the aerosol generating rod 31 is inserted into the heating tank through the pressure cap structure 24 and the contact member 25, the multiple fourth protrusions 251 on the inner side of the contact member 25 abut against the outer wall of the aerosol generating rod 31 to limit and fix the aerosol generating rod 31. At the same time, a gap is formed in the area between two adjacent fourth protrusions 251 to allow airflow to pass through. The intake airflow passes through the first air passage 241 and the second air passage 235 into the mounting cavity 231 of the support base 23 and flows to one end of the air inlet 112 of the heat pipe 11.
[0086] like Figures 14 to 15In the example, when the heating element 13 is energized and heats up, the insertion section 115 of the heat pipe 11 can preheat the aerosol generating rod 31. During the suction action, the airflow flows into the heat exchange section 114 of the heat pipe 11 from the air inlet 112 under negative pressure, and is heated to form a hot airflow when passing through multiple vents 121 on the heat exchange core 12. This hot airflow then flows to the aerosol generating rod 31, where it is heated and atomized to generate aerosol, which is then carried to the suction end 312. During the entire usage phase, during the first suction action, the power supply component 22 controls both heating parts 130 of the heating element 13 to heat up simultaneously, thereby heating the heat exchange core 12 as a whole. The resulting hot airflow has a high temperature to meet the heating requirements of the aerosol generating rod 31 during the first suction action. In subsequent suction actions, the power supply component 22 controls only one heating part 130 of the heating element 13 to heat up, which is sufficient to meet the heating requirements of the aerosol generating rod 31. In addition, the second groove 1151 in the insertion section 115 of the heat pipe 11 is close to the heat exchange section 114. Since the radial distance of the area where the second groove 1151 is provided relative to the aerosol generating rod 31 is larger than that of other areas, the heating amount of the sidewall of the insertion section 115 to the aerosol generating rod 31 in this area can be reduced. This allows the position of the aerosol generating rod 31 near the air inlet 311 to be mainly heated by the hot air flow, and the heat of the heat pipe 11 is more effectively conducted to the area in the insertion section 115 where the second groove 1151 is not provided (i.e., the area away from the heat exchange section 114 in the first direction), so that the heat distribution is more uniform.
[0087] When the atomizing device 200 of this application heats the aerosol generating rod 31, the heating element 13 can be heated locally or as a whole, so as to adjust the heat output of the heating element 13 according to the different heating requirements of the suction action at different stages. This prevents the aerosol generating rod 31 from being overheated or scorched, which is beneficial to improving the atomization effect and improving the user experience.
