[0036] The application will be described in further detail below with reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following embodiments, many details are described in order to provide a better understanding of the application. However, a person skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification in order to avoid the core of the application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for a person skilled in the art based on the description in the specification and general technical knowledge in the art.

[0037] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be sequentially adjusted or adjusted in a manner that is obvious to a person skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the composition and / or order is necessary.

[0038] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connections (couplings) unless otherwise specified.

[0039] The heating device provided in the application has a heater with air holes and a heating column extending out of the heater, and a heat insulation member is arranged outside the proximal end region of the extending part of the heating column. When an aerosol generating stick (containing an atomized substrate) is inserted into the atomization device using the heating device, the air holes of the heater are opposite to the end face of the aerosol generating stick to form a hot gas flow through the air holes, and the extending part of the heating column can be inserted into the aerosol generating stick to realize the combination of hot gas flow heating and heating column heating. The heat insulation member of the heating column can insulate the proximal end region of the extending part, thereby reducing the heat conduction amount of the proximal end region to the aerosol generating stick, correspondingly increasing the heat conduction amount of the distal end region of the extending part, thereby reducing the temperature difference between different regions of the extending part, so that the aerosol generating stick is heated more uniformly.

[0040] Some embodiments of the heating device and the atomization device provided in the application will be described below with reference to the accompanying drawings.

[0041] In the embodiments of the first aspect of the application, as shown in Figure 1 , Figure 2 and Figure 3 , the heating device 100 includes a heater 11, a heating column 12, and a heat insulation member 13. In the first direction, the heater 11 has oppositely arranged first and second ends 111 and 112, and a plurality of air holes 1131 are formed through the heater 11 in the first direction; when applied to an atomization device, the heater 11 can be electrically connected to a power supply assembly and generate heat in an energized state. The heating column 12 is connected to the heater 11, and the extending part 121 of the heating column 12 extends out of the first end 111 of the heater 11 and extends in the first direction, and the heating column 12 can conduct part of the heat generated by the heater 11 in the first direction. In the first direction, the extending part 121 of the heating column 12 includes a proximal end region 1211 and a distal end region 1212, the proximal end region 1211 is close to the first end 111 of the heater 11, and the distal end region 1212 is away from the first end 111 of the heater 11. The heat insulation member 13 is connected to the extending part 121 and circumferentially covers at least part of the proximal end region 1211; when the aerosol generating stick 300 is inserted into the atomization device 200 using the heating device 100, as shown in the example in Figure 4 , the heat insulation member 13 can be inserted into the aerosol generating stick 300 together with the extending part 121 of the heating column 12, and the heat insulation member 13 reduces the heat conduction of the proximal end region 1211 of the extending part 121 to the side, so that more heat is conducted to the distal end region 1212 of the extending part 121, and then conducted to the inside of the aerosol generating stick 300 by the distal end region 1212.

[0042] It can be understood that in the existing atomization device, the heat conduction amount of the heating column 12 or the heating needle in the extension direction thereof is generally different, resulting in temperature difference between different areas of the heating column 12 or the heating needle, and the farther away from the heater 11, the lower the temperature, which is easy to cause the phenomenon of uneven heating of the aerosol generating stick.

[0043] In the embodiment, the structure of the heating device 100 is improved and optimized, the heat insulation piece 13 is arranged on the proximal end area 1211 of the protruding part 121 of the heating column 12, and the heat insulation piece 13 can be inserted into the aerosol generating stick together with the protruding part 121, so as to reduce the heat conduction amount of the proximal end area 1211 in the lateral direction, correspondingly increase the heat conduction amount of the distal end area 1212, thereby reducing the temperature difference between different areas of the protruding part 121, so as to make the aerosol generating stick heat more evenly and prevent local overheating, which is beneficial to improve the user experience.

[0044] It should be noted that in actual application, the hot gas flow heating and the heating column heating of the atomization device can be complementary to each other, the heating column can be used as an auxiliary heating mode to continuously conduct heat, and the hot gas flow heating flows to the aerosol generating stick and heats when the user performs the suction action, forming intermittent heating, and the two heating modes are organically combined to meet the heating requirements of the aerosol generating stick. Figure 4 As shown in the state shown in the

[0045] In addition, the heater 11, the heating column 12 and the heat insulation piece 13 can adopt corresponding materials according to the needs of use, for example, the part for heat conduction in the heater 11 and the heating column 12 can adopt metal or non-metal materials with good heat conduction performance, and the heat insulation piece 13 can adopt a material with low heat conductivity, such as ceramic.

[0046] In further embodiments of the present application, as shown in Figure 3 , Figure 4 The heat insulation piece 13 of the heating device 100 adopts a cylindrical structure and is directly sleeved outside the proximal end area 1211 of the heating column 12; wherein, the area of the proximal end area 1211 covered by the heat insulation piece 13 in the circumferential direction can be set according to actual needs, that is, the heat insulation piece 13 can cover part or all of the proximal end area 1211 in the circumferential direction, preferably, the heat insulation piece 13 extends one circle in the circumferential direction to cover all of the proximal end area 1211, and the heat insulation effect is better.

[0047] Further, as shown in Figure 3 and Figure 4In the example, the end of the heat insulation member 13 facing the heater 11 in the first direction abuts against the first end 111 of the heater 11 to form an axial limit on the heat insulation member 13. The heat insulation member 13 and the heating column 12 can be fixed by means of snap-fit, welding, threaded connection, interference fit, etc.; to further improve the connection stability between the heating column 12 and the heat insulation member 13, the heating column 12 can adopt a cylindrical structure adapted to the size of the heat insulation member 13.

[0048] Furthermore, such as Figure 3 In the example, in the first direction, the length ratio of the heat insulation element 13 to the protrusion 121 is in the range of 50% to 70%, that is, the length of the heat insulation element 13 accounts for 50% to 70% of the total length of the protrusion 121, for example, 55%, 60%, or 65%. It is understood that if the length ratio of the heat insulation element 13 to the protrusion 121 is too low, some of the heat from the protrusion 121 will still be conducted laterally from the proximal region 1211, making it difficult to effectively reduce the temperature difference between the proximal region 1211 and the distal region 1212; if the length ratio of the heat insulation element 13 to the protrusion 121 is too high, most of the heat will be conducted from the limited space of the distal region 1212 to the aerosol generating rod 300, easily causing an abnormal increase in the temperature of the distal region 1212. Neither of these situations is conducive to achieving a balanced temperature difference, while the length ratio set in this embodiment effectively balances both situations, resulting in a better temperature difference balance.

[0049] Furthermore, in a specific implementation, such as Figure 3 , Figure 5 and Figure 6 As shown, the distal region 1212 of the heating column 12 has a first protrusion 1213 that protrudes radially outward. The end of the heat insulation member 13 furthest from the heater 11 in a first direction abuts against the first protrusion 1213, so that the first protrusion 1213 and the first end 111 of the heater 11 respectively form an abutment from both ends of the heat insulation member 13, thereby fixing and limiting the heat insulation member 13. Wherein, as... Figure 5 and Figure 6 In the example, the first protrusion 1213 can be a cylindrical boss structure, that is, extending around the perimeter to fit the cylindrical structure of the heat insulation member 13, and the first protrusion 1213 extends to the distal end of the heating column 12 in the first direction to reduce resistance when inserted into the aerosol generating rod 300.

[0050] Of course, the first protrusion 1213 is not limited to Figure 5 and Figure 6In the form shown in FIG. 12, the first protruding portion 1213 can also adopt one or more bump structures, and can also achieve the axial limiting effect on the heat insulation piece 13. In actual application, it can be processed according to specific assembly requirements and structural design. It should be noted that the first protruding portion 1213 can be a structure integrally formed with the heating column 12, and of course can also be a separate structure separate from the heating column 12, and is assembled on the heating column 12 by a connecting manner.

[0051] In another specific implementation manner, as shown in FIG. 13, Figure 7 In the form shown in FIG. 13, the heat insulation piece 13 is sleeved on the protruding portion 121 of the heating column 12, and the end of the heat insulation piece 13 away from the heater 11 has an annular inclined surface structure 131. The annular inclined surface structure 131 gradually inclines to the direction close to the center axis of the protruding portion 121 in the direction close to the distal end region 1212 along the first direction, so as to form a transition region. When the heating column 12 is inserted into the inside of the aerosol generating stick 300, the annular inclined surface structure 131 arranged in an inclined manner can play a guiding role to reduce the resistance, so that the heat insulation piece 13 can be relatively smoothly inserted into the inside of the aerosol generating stick 300. The annular inclined surface structure 131 and the heating column 12 can be connected and fixed by welding, bonding or interference fit.

[0052] In further embodiments of the present application, as shown in FIG. 14, Figures 1 to 3 As shown in FIG. 14, the heater 11 includes a heating base 113, a heating element 114 and a heat insulation sleeve 115. The heating base 113 is provided with a plurality of air holes 1131, and the plurality of air holes 1131 are arranged at intervals in the circumferential direction. The heating column 12 is connected to the heating base 113. The heating element 114 is connected to the outer side wall of the heating base 113, and the heating element 114 is an electric heating element. The heating element 114 can be electrically connected to a power supply assembly and generates heat in a powered state, and conducts the generated heat to the heating base 113, so that the air flowing through the air holes 1131 is heated to form a hot air flow, and part of the heat is conducted to the heating column 12. The heat insulation sleeve 115 adopts a cylindrical structure and penetrates in the first direction. The heat insulation sleeve 115 is sleeved on the outer side of the heating element 114 to achieve heat insulation effect on the heating element 114 and the heating base 113 in the lateral direction, so as to reduce the heat loss in the lateral direction. In the projection plane perpendicular to the first direction, the protruding portion 121 of the heating column 12 and the plurality of air holes 1131 are located in the heat insulation sleeve 115, so that the air flow can normally flow into the air holes 1131 to form a hot air flow.

[0053] Further, in one specific implementation manner, as shown in FIG. 15, Figure 3 , Figure 5 and Figure 6In the example shown, the heat insulation sleeve 115 has a second protrusion 1151 on the inner side of one end of the extension 121 of the heating column 12. The second protrusion 1151 protrudes radially inward to abut against the heating base 113 in a first direction. Correspondingly, the heating base 113 has a bent plate 1134 at one end in the first direction away from the second protrusion 1151. A portion of the bent plate 1134 protrudes radially outward (the bent plate 1134 in the figure is in an unbent state) and abuts against the end face of the heat insulation sleeve 115, so that the heating base 113 and the heat insulation sleeve 115 are fixed together, and the heating element 114 is limited and fixed by the second protrusion 1151 and the bent plate 1134 at both ends in the first direction.

[0054] It should be noted that the heating element 114 can be in the form of a heating mesh or a heating plate. Alternatively, the heating element 114 can be fixed by selecting an appropriate size for the heat insulation sleeve 115 to form a compression fixation on the side, or the heating element 114 can be fixed by fixing adhesive.

[0055] In another implementation, such as Figure 5 and Figure 6 In the example shown, the heat insulation sleeve 115 has a side opening 1152 on its side wall, and the side opening 1152 extends through both ends of the heat insulation sleeve 115 in a first direction, meaning that the heat insulation sleeve 115 is an open structure in the circumferential direction. Correspondingly, the heating element 114 has a conductive structure 1141, which extends from the side opening 1152 of the heat insulation sleeve 115 and extends outside the heat insulation sleeve 115 in the first direction, so that when applied to an atomizing device, it can be electrically connected to the power supply component through the conductive structure 1141. Specifically, the conductive structure 1141 can be a pin structure or a lead wire structure. By opening a side opening 1152 on the heat insulation sleeve 115 to reserve space for the conductive structure 1141 of the heating element 114, it is possible to avoid squeezing the conductive structure 1141 on the one hand, and to prevent radial gaps between the heat insulation sleeve 115 and the heating element 114 on the other hand, so that the assembly between the heat insulation sleeve 115, the heating element 114 and the heating base 113 can be more compact.

[0056] In further embodiments of this application, such as Figure 3 As shown, the end of the extension 121 of the heating column 12 away from the heater 11 has a spike 1214 to reduce resistance when inserted into the aerosol generating rod 300, so that the extension 121 of the heating column 12 can be inserted into the aerosol generating rod 300 more smoothly.

[0057] In further embodiments of this application, the heating column 12 and the heating base 113 can be connected in different ways. In one specific implementation, such as Figure 8As shown, the heating base 113 and the heating column 12 are integrally formed to reduce the connection structure and facilitate simplification of the overall structure.

[0058] In another specific implementation manner, as shown in Figure 3 the heating base 113 has a first through hole 1132 penetrating in the first direction, and a nut insert 1133 is embedded in one end of the first through hole 1132 away from the extension part 121 of the heating column 12, and the nut insert 1133 is fixedly integrated with the heating base 113. The heating column 12 is arranged in the first through hole 1132 of the heating base 113, and the heating column 12 has an external threaded area 122 away from the extension part 121. During assembly, the external threaded area 122 of the heating column 12 is threadedly connected with the nut insert 1133, so that the heating column 12 is detachably connected with the heating base 113, facilitating assembly.

[0059] In yet another specific implementation manner, as shown in Figure 9 the heating base 113 has a second through hole 1135 penetrating in the first direction, and the second through hole 1135 is a threaded hole; correspondingly, the heating column 12 has an external threaded area 122 away from the extension part 121, and the heating column 12 is arranged in the second through hole 1135 and is threadedly connected with the second through hole 1135 through the external threaded area 122, so that the heating column 12 is detachably connected with the heating base 113, facilitating assembly.

[0060] It should be noted that the positions of the first through hole 1132 and the second through hole 1135 can be set according to specific use requirements. When the first through hole 1132 and the second through hole 1135 are located at the center position of the heating base 113, the heating column 12 can form a center column after assembly, and the heating column 12 is more uniformly heated in all directions.

[0061] In the embodiment of the second aspect of the present application, an atomization device 200 is provided, as shown in Figure 4 , Figure 10 and Figure 11As shown, the atomizing device 200 includes a housing 21, a receiving tank 22, a heating device 100 as described in any of the embodiments of the first aspect, and a power supply assembly 23. In the first direction, one end of the housing 21 has an assembly port 211; both the heating device 100 and the power supply assembly 23 are disposed within the housing 21. A portion of the receiving tank 22 extends into the housing 21 through the assembly port 211, and one end of the receiving tank 22 extending into the housing 21 has a heating port 221; the receiving tank 22 is detachably connected to the housing 21. The heating device 100 is correspondingly disposed at the end of the receiving tank 22 with the heating port 221. On a projection plane perpendicular to the first direction, the heating column 12 and multiple vent holes 1131 are located inside the heating port 221, and the protruding portion 121 of the heating column 12 of the heating device 100 extends into the receiving tank 22 through the heating port 221. The power supply assembly 23 is electrically connected to the heater 11 of the heating device 100 to supply power to the heater 11. Among them, such as Figure 3 In the example, the first direction is the height direction of the housing 21.

[0062] During use, the aerosol generating rod 300 is inserted into the receiving tank 22, such as... Figure 4 In the example shown, the heating column 12 can be inserted into the aerosol generating rod 300 along the first direction. The heater 11 heats up when energized, and this heat is conducted to the interior of the aerosol generating rod 300 through the heating column 12, creating continuous heating. When the user performs a suction action, the air flowing through the vent 1131 is heated and forms a hot airflow, which in turn heats the aerosol generating rod 300. After use, the receiving tank 22 and the aerosol generating rod 300 can be removed together from the assembly port 211, as shown. Figure 12 The example in the image is to prevent residue generated by the aerosol generating rod 300 from falling into the housing 21.

[0063] In further embodiments of this application, such as Figure 4 As shown, the atomizing device 200 also includes a first cylinder 24 and an interface component 25. The first cylinder 24 is disposed within the housing 21 and extends through both ends in a first direction; one end of the first cylinder 24 communicates with the assembly port 211 to provide installation space for the receiving groove 22. A portion of the receiving groove 22 is disposed within the first cylinder 24 and is fixedly engaged with it. When the receiving groove 22 needs to be removed, the engagement between the receiving groove 22 and the first cylinder 24 can be released. Figure 4In the example, at least a portion of the heating device 100 is located within the first cylindrical body 24 to fit into the receiving tank 22. The interface member 25 is a through-structure in a first direction, located at the assembly port 211 of the housing 21, and abuts against the end face of the first cylindrical body 24 communicating with the assembly port 211. The end of the receiving tank 22 located outside the assembly port 211 is detachably connected to the interface member 25. The interface member 25 and the first cylindrical body 24 can be removed from the assembly port 211 of the housing 21 by operating the interface member 25. Figure 12 The example in the text shows how the aerosol generating rod 300 can be removed together with the aerosol generator after the user has finished using it.

[0064] Furthermore, such as Figure 4 In the example, the interface component 25 and the receiving groove 22 can be fixed by a snap-fit ​​method. For example, a matching snap-fit ​​structure can be provided on the inner wall of the interface component 25 and the outer wall of the receiving groove 22 to achieve snap-fit ​​fixation. A similar fixing method can also be used between the first cylinder 24 and the receiving groove 22, that is, a matching snap-fit ​​structure can be provided on the inner wall of the first cylinder 24 and the outer wall of the receiving groove 22 to achieve snap-fit ​​fixation, and the snap-fit ​​state can be released under the action of external force to facilitate removal.

The first support member 26 is in the form of a support seat and is fixedly connected to the housing 21 as a whole, and gas can flow into the first air inlet 263 through the first support member 26. Correspondingly, the second support member 27 is provided in the mounting groove 261. The second support member 27 has a second air inlet 271 that runs through in a first direction, and the second air inlet 271 is a stepped hole.

One end of the heating column 12 away from the nut insert 1133 extends out of the first through hole 1132 and forms an extension 121, and one end of the extension 121 away from the heating base 113 has a sharp portion 1214. As shown in the example in Figure 4 , in the projection plane perpendicular to the first direction, the heating column 12 and the plurality of air holes 1131 are located inside the heating opening 221, and the sharp portion 1214 of the heating column 12 penetrates through the heating opening 221 and extends into the accommodating groove 22.

[0072] As shown in the example in Figure 2 and Figure 3 , the heating element 114 is connected to the outer side wall of the heating base 113, and the heating element 114 is an electric heating element, which is electrically connected with the power supply assembly 23 and generates heat in the energized state, and conducts the generated heat to the heating base 113, so that the air flowing through the air holes 1131 is heated to form a hot air flow, and part of the heat is conducted to the heating column 12. The heating base 113 has a cylindrical structure, and the heat insulation sleeve 115 has a corresponding cylindrical structure and extends in the first direction; the heat insulation sleeve 115 is sleeved on the outer side of the heating element 114 to laterally insulate the heating element 114 and the heating base 113, so as to reduce the lateral heat loss.

[0073] As shown in the example in Figures 1 to 4 , in the first direction, the extension 121 of the heating column 12 comprises a proximal end region 1211 and a distal end region 1212, the proximal end region 1211 is close to the first end 111 of the heater 11, and the distal end region 1212 is away from the first end 111 of the heater 11. The heat insulation piece 13 has a structure of a ceramic ring, which is sleeved on the proximal end region 1211 of the extension 121 and circumferentially covers a circumference of the proximal end region 1211. As shown in the example in Figure 3 , Figure 5and Figure 6 In the example in FIG. 12, the distal end region 1212 of the heating column 12 has a first protruding part 1213 protruding radially outward, which is specifically a cylindrical boss structure; the thermal insulation piece 13 abuts against the first protruding part 1213 at one end thereof away from the heater 11 in the first direction, and the other end of the thermal insulation piece 13 abuts against the heating base 113 to achieve fixation and positioning of the thermal insulation piece 13. In the first direction, the length ratio of the thermal insulation piece 13 to the protruding part 121 is within a range of 50% to 70%, i.e., the length of the thermal insulation piece 13 accounts for 50% to 70% of the total length of the protruding part 121.

[0074] As shown in FIG. 13, Figure 3 , Figure 5 and Figure 6 In the example in FIG. 13, the thermal insulation sleeve 115 has a second protruding part 1151 protruding radially inward toward the inner side of one end of the protruding part 121 of the heating column 12, to abut against the heating base 113 in the first direction. Correspondingly, the heating base 113 has a bent plate 1134 at one end thereof away from the second protruding part 1151 in the first direction, a part of the bent plate 1134 protruding radially outward (the bent plate 1134 is in an unbent state in the figure), and abutting against the end face of the thermal insulation sleeve 115 to form fixation between the heating base 113 and the thermal insulation sleeve 115, and to form positioning and fixation of the heating element 114 by the two ends of the second protruding part 1151 and the bent plate 1134 in the first direction. As shown in FIG. 14, Figure 5 and Figure 6 In the example in FIG. 14, the side wall of the thermal insulation sleeve 115 has a side opening 1152, and the side opening 1152 penetrates through both ends of the thermal insulation sleeve 115 in the first direction, i.e., the thermal insulation sleeve 115 is in a non-enclosed structure form in the circumferential direction. Correspondingly, the heating element 114 has a conductive structure 1141, such as a pin structure; the conductive structure 1141 protrudes from the side opening 1152 of the thermal insulation sleeve 115 and extends to outside of the thermal insulation sleeve 115 in the first direction; the installation groove 261 has a wire passing hole, and the conductive structure 1141 passes through the wire passing hole and is electrically connected to the power supply assembly 23.

[0075] In use, as shown in FIG. 15, Figure 4In the example, the aerosol generating rod 300 is inserted into the receiving tank 22, and the heating column 12 is inserted into the aerosol generating rod 300 along a first direction. The heating element 114 of the heater 11 heats up when energized, and the heat is conducted to the interior of the aerosol generating rod 300 through the heating base 113 and the heating column 12, forming continuous heating. The heat insulation element 13 is also inserted into the aerosol generating rod 300 to insulate the proximal region 1211 of the heating column 12, so that more heat is conducted to the distal region 1212 and into the aerosol, thereby balancing the temperature difference between the proximal region 1211 and the distal region 1212. When the user performs a suction action, the air flowing through the vent 1131 is heated and forms a hot airflow, which in turn heats the aerosol generating rod 300.

[0076] When the use is finished, such as Figure 12 In the example, the interface 25, the receiving tank 22, and the aerosol generating rod 300 can be removed together from the assembly port 211 by operating the interface 25, so as to prevent the residue generated by the aerosol generating rod 300 from falling into the housing 21.
