[0002] Currently, in common heated non-combustible atomizing devices, an aerosol generating rod is inserted into a heating chamber for heating, causing the atomizing matrix stored inside the rod to atomize. However, because the aerosol generating rod has a certain lateral width, it takes time for heat to fully penetrate its interior and heat the central part to reach the preset temperature to generate aerosol. During this process, some heat loss occurs, resulting in low heating efficiency. The long waiting time also affects the user experience. Utility Model Content

[0036] 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.
[0037] 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.

[0038] An aerosol generator is a special atomizing product containing an atomizing matrix. When in use, it is inserted into a matching heated non-combustible atomizing device. The heating element heats the aerosol generator, causing the atomizing matrix inside the aerosol generator to atomize and generate an aerosol. As the user draws the aerosol generator, the aerosol moves with the airflow to the suction end.
[0039] The heating device provided in this application can be applied in atomizing equipment and electrically connected to the power supply component of the atomizing equipment for heating and atomizing the aerosol generating rod. By providing a pressure cap structure and mounting groove in the support member to clamp and fix the heating component, and by setting the dimension of the heating chamber in the second direction perpendicular to the first direction to be smaller than the diameter of the corresponding aerosol generating rod, the aerosol generating rod can be compressed in the second direction when inserted into the heating chamber. This reduces the width of the aerosol generating rod in the second direction, allowing heat to enter the interior of the aerosol generating rod more quickly, and enabling the atomizing matrix to reach the target temperature and generate aerosol more rapidly.
[0040] Wherein, the first direction is the height direction of the heating device, and the second and third directions are both perpendicular to the first direction, with the second direction being perpendicular to the third direction. When the heating device is assembled in an atomizing device, the first direction corresponds to the height direction of the atomizing device, and of the second and third directions, one corresponds to the width direction of the atomizing device, and the other corresponds to the thickness direction of the atomizing device. The following embodiments are the same.
[0041] The following describes some embodiments of the heating device and atomizing equipment provided in this application with reference to the accompanying drawings.
[0042] The first aspect of this application provides a heating device 100, such as... Figure 1 , Figure 2 , Figure 3As shown, the heating device 100 includes a support member 1 and a heating assembly 2. The support member 1 has a mounting cavity 111, and the heating assembly 2 is disposed in the mounting cavity 111 so that when applied in an atomizing device, the heating assembly 2 can be assembled and fixed by the support member 1. In a first direction, one end of the mounting cavity 111 of the support member 1 is an open end 112, and the other end is a closed end 121; the open end 112 is for the aerosol generating rod 500 to pass through, the inner sidewall of the open end 112 has a capping structure 113, and the closed end 121 has a mounting groove 123 on the side facing the open end 112. The heating assembly 2 has a heating chamber 211 that can accommodate the aerosol generating rod 500. In a first direction, one end of the heating assembly 2 abuts against the cap structure 113 of the support member 1, so that the aerosol generating rod 500 can pass through the opening end 112 and be inserted into the heating chamber 211. The end of the heating assembly 2 away from the opening end 112 abuts against the side wall of the mounting groove 123, so that the heating assembly 2 is clamped and fixed by the cap structure 113 and the mounting groove 123. The second direction is a transverse direction perpendicular to the first direction. The width dimension of the heating chamber 211 in the second direction is smaller than the diameter dimension of the corresponding aerosol generating rod 500, so that when the aerosol generating rod 500 is inserted into the heating chamber 211, the inserted part can be compressed in the second direction to reduce the width dimension of the part in the second direction. So that when the heating assembly 2 heats the aerosol, the heat can enter the interior of the aerosol generating rod 500 more quickly in the second direction, and the atomizing matrix inside it can reach the target temperature more quickly to generate aerosol.
[0043] It is understandable that common aerosol generators have a cylindrical structure, with the atomizing matrix typically stored inside the aerosol generator in the area corresponding to the insertion part. Existing atomization devices use a circular chamber for the heating cavity, adapted to the aerosol generator. During heating, the heat emitted by the heating element penetrates the aerosol generator and enters the area where the atomizing matrix is stored, thus raising the temperature of the atomizing matrix. Therefore, there is a correlation between the diameter of the aerosol generator and the time required to heat the atomizing matrix; that is, the larger the diameter of the aerosol generator, the longer it takes for heat to penetrate the aerosol generator and heat the atomizing matrix to generate aerosol. Since some heat loss is inevitable during heating, the longer the heating time, the greater the heat loss, the greater the heating energy consumption, and the longer the user's waiting time.
[0044] The heating device in this embodiment, through structural improvements and optimizations, employs a heating component with a non-circular heating cavity. This ensures that the width of the heating cavity in at least one direction is smaller than the diameter of the matching aerosol generating rod. When the aerosol generating rod is inserted into the heating cavity, the inserted portion can be compressed, thereby reducing the width of the aerosol generating rod in that direction. This shortens the time required to heat the internal atomizing matrix and generate aerosol in that direction, which helps reduce energy consumption, improve heating efficiency, and also shortens user waiting time, thus improving the user experience.
[0045] It should be noted that the heating chamber 211 can be shaped to match the aerosol generating rod 500 and satisfy the above-mentioned size relationship, for example... Figures 1 to 3 The shape shown is elliptical, or has an arc shape in the circumferential region. Furthermore, the air intake method of the heating device 100 can be set according to actual usage needs; for example, it can adopt... Figure 2 The method of air intake from the top of the heating chamber 211 shown can also be achieved by opening a hole at the bottom of the support member 1, or by opening a hole on the side to achieve lateral air intake.
[0046] In further embodiments of this application, such as Figure 4 As shown, the heating assembly 2 includes a heating tube 21, a heating element 22, and a heat insulation sleeve 23. Figures 1 to 5As shown, the heating tube 21 serves as a heat-conducting structure and is arranged along the first direction. One end of the heating tube 21 facing the closed end 121 abuts against the side wall of the mounting groove 123. The space inside the heating tube 21 forms a heating cavity 211, which is specifically an elliptical cross-section cavity with the minor axis of the ellipse arranged along the second direction and the major axis arranged along the third direction. When the aerosol generating rod 500 is inserted into the heating cavity 211, the two side walls of the heating tube 21 in the second direction clamp the aerosol generating rod 500 and compress it to a certain size. A heating element 22 is arranged circumferentially on the outer side wall of the heating tube 21. The heating element 22 can be electrically connected to the power supply component to generate heat when energized and conduct heat to the aerosol generating rod 500 through the heating tube 21. The heating element 22 includes at least two sub-heating segments staggered in the first direction to correspond to different areas of the heating part of the aerosol generating rod 500. A heat insulation sleeve 23 is fitted onto the outside of the heating tube 21. The heating element 22 is located between the heat insulation sleeve 23 and the heating tube 21, and is fixed to the outer wall of the heating tube 21 by the heat insulation sleeve 23. The end of the heat insulation sleeve 23 facing the closed end 121 is a through structure, and the end of the heat insulation sleeve 23 facing the open end 112 has a first opening 231. The outer periphery of the first opening 231 abuts against the pressure cap structure 113 of the support member 1, and the inner periphery of the first opening 231 abuts against the end of the heating tube 21 facing the open end 112, so as to realize the assembly and fixation between the heating tube 21, the heat insulation sleeve 23 and the support member 1. Moreover, the first opening 231 is connected to the heating cavity 211 of the heating tube 21, so that the aerosol generating rod 500 can pass through the first opening 231 and enter the heating cavity 211. Figure 6 The state shown in the image.
[0047] During heating, the heating element 22 can be controlled to heat different sub-heating segments independently through the power supply component. According to the corresponding heating sequence and heating duration, such as a combination of segmented heating and common heating, the atomizing matrix can generate aerosol more uniformly during the continuous heating and atomization process. The aerosol can also maintain consistency as it flows with the airflow to the suction end, preventing excessive or attenuated air output from the suction end.
[0048] In further embodiments of this application, such as Figure 2 , Figure 3 and Figure 7In the example, the short axis of the heating chamber 211 is arranged along the second direction and is smaller than the diameter of the corresponding aerosol generating rod 500. Correspondingly, the long axis of the heating chamber 211 is arranged along the third direction and is larger than the diameter of the corresponding aerosol generating rod 500. This allows the heating chamber 211 to form air inlet gaps 212 on both sides of the aerosol generating rod 500 in the third direction when the aerosol generating rod 500 is inserted into the heating chamber 211. The air inlet gaps 212 communicate with the mounting groove 123. Correspondingly, the bottom wall of the mounting groove 123 has a plurality of first protrusion structures 1231, which are spaced circumferentially to abut against the end face of the aerosol generating rod 500 inserted into the heating chamber 211. This allows the airflow flowing into the mounting groove 123 from the air inlet gaps 212 to flow through the gaps in the first protrusion structures 1231 and enter the interior of the aerosol generating rod 500. The elliptical heating cavity 211 is designed to compress the aerosol generating rod 500 while simultaneously allowing air to enter from the top. This eliminates the need for additional air inlets and channels, simplifying the structure and facilitating assembly.
[0049] Furthermore, such as Figure 2 , Figure 3 and Figure 7 In the example, the thickness of the heating element 21 remains consistent in the circumferential direction, meaning that the thickness of the heating element 21 is the same at any position in the circumferential direction, so that the heating element 21 can conduct heat more uniformly. The ratio of the major axis L2 to the minor axis L1 of the heating chamber 211 is in the range of 1.1 to 1.5, so that when the aerosol generating rod 500 is inserted into the heating chamber 211, the compression in the second direction is kept within a suitable range. This improves heating efficiency while preventing excessive compression from causing significant changes in the distribution of the atomizing matrix and affecting aerosol generation. For example, as... Figure 2 and Figure 7 In the example, the heating chamber 211 of the heating tube 21 can be set with a major axis L2 of 8.5 mm, a minor axis L1 of 6.5 mm, a tube wall thickness of 0.5 mm, and a diameter of the aerosol generating rod 500 in the range of 7.6 mm to 8 mm. After the aerosol generating rod 500 is inserted into the heating chamber 211, its width in the second direction is compressed to 6.5 mm, and the compression is maintained in the range of 15% to 30%. Meanwhile, air inlet gaps 212 with a width of 0.5 mm to 0.9 mm are formed on both sides in the third direction to allow external air to enter.
[0050] Furthermore, in a specific example, such as Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, the mounting groove 123 is specifically an elliptical groove, and its size matches that of the heating tube 21, so that the end of the aerosol generating rod 500 inserted into the heating chamber 211 can enter the mounting groove 123 and abut against the first protruding structure 1231. The inner wall of the mounting groove 123 has a first step structure 1232 and a second step structure 1233, and the first step structure 1232 and the second step structure 1233 are arranged sequentially from the inside to the outside, that is, the first step structure 1232 is located inside the second step structure 1233. Correspondingly, the end of the heating tube 21 of the heating assembly 2 facing the closed end 121 abuts against the first step structure 1232, and the end of the heat insulation sleeve 23 facing the closed end 121 abuts against the second step structure 1233, so as to support and limit the heating assembly 2.
[0051] Furthermore, in a specific example, such as Figure 5 , Figure 6 and Figure 9 As shown, the pressure cap structure 113 of the support member 1 is specifically an annular structure with a second opening 1131, and the second opening 1131 is elliptical to fit the first opening 231 and the heating cavity 211. On the projection plane perpendicular to the first direction, the first opening 231 is located inside the second opening 1131 to keep the first opening 231 and the heating cavity 211 unobstructed in the first direction, so as to avoid being blocked by the pressure cap structure 113 and affecting the assembly of the aerosol generating rod 500.
[0052] In further embodiments of this application, such as Figures 4 to 7 and Figure 10 In the example, in the heating assembly 2, the sub-heating section of the heating element 22 is at least divided into a first sub-heating section 221 and a second sub-heating section 222. In the second direction, the first sub-heating section 221 and the second sub-heating section 222 are located on both sides of the heating tube 21, and both the first sub-heating section 221 and the second sub-heating section 222 extend circumferentially along the heating tube 21 to adhere to the surface of the heating tube 21, so that heat can be quickly and evenly conducted into the heating tube 21 during heating. When applied in an atomizing device, the first sub-heating section 221 and the second sub-heating section 222 can each form an electrical connection with the power supply assembly, that is, the first sub-heating section 221 and the second sub-heating section 222 form a parallel relationship. The power supply assembly can supply power to the first sub-heating section 221 or the second sub-heating section 222 individually, or it can supply power to the first sub-heating section 221 and the second sub-heating section 222 simultaneously, so that different heating methods can be adopted according to different heating needs.
[0053] Furthermore, among them, such as Figure 5 , Figure 7 and Figure 11 and Figure 12In the example shown, in the first direction, the first sub-heating segment 221 and the second sub-heating segment 222 are staggered, with the first sub-heating segment 221 protruding towards the opening end 112 relative to the second sub-heating segment 222, and the first sub-heating segment 221 and the second sub-heating segment 222 having a certain overlap area in the second direction. When heating the aerosol generating rod 500, an appropriate heating method can be adopted to prevent heat attenuation during the flow of air inside the aerosol generating rod 500, which would affect the generation of aerosols, and to maintain a high degree of consistency in the generation and concentration of aerosols during continuous heating.
[0054] For example, at the beginning of heating, the first sub-heating section 221 can be controlled to heat up independently to achieve preheating. After a first preset time, the second sub-heating section 222 is activated, and its temperature rises while the temperature of the first sub-heating section 221 decreases until the temperatures of the first and second sub-heating sections 221 are the same, maintaining the current heating temperature for continuous heating. This heating control method ensures that the mixed gas flowing from the suction end of the aerosol generating rod 500 meets the user's needs, thus improving the user experience.
[0055] It should be noted that in practical applications, the heating method is not limited to the one shown in the example above. Other heating control methods can also be used depending on the different settings of the sub-heating sections.
[0056] Furthermore, such as Figure 7 , Figure 11 and Figure 12As shown, both the first sub-heating segment 221 and the second sub-heating segment 222 of the heating element 22 have a mesh-like structure. When the first sub-heating segment 221 and the second sub-heating segment 222 are attached to the outer wall of the heating tube 21, the contact area of the heating element can be reduced and energy consumption reduced while meeting the heat conduction requirements. In the circumferential direction of the heating tube 21, one end of the first sub-heating segment 221 has a first pin structure 2231, and the end of the second sub-heating segment 222 near the first pin structure 2231 in the circumferential direction has a second pin structure 2232. There is a certain distance between the first pin structure 2231 and the second pin structure 2232. The end of the first sub-heating segment 221 away from the first pin structure 2231 is connected to the end of the second sub-heating segment 222 away from the second pin structure 2232, and a third pin structure 2233 is provided at the connection point. The third pin structure 2233 serves as a common pin. When the first pin structure 2231 and the third pin structure 2233 are energized, the first sub-heating segment 221 is energized and heats up; when the second pin structure 2232 and the third pin structure 2233 are energized, the second sub-heating segment 222 is energized and heats up; when the first pin structure 2231, the second pin structure 2232, and the third pin structure 2233 are simultaneously energized, the first sub-heating segment 221 and the second sub-heating segment 222 are simultaneously energized and heat up. For example, Figure 10 In the example shown, the first pin structure 2231, the second pin structure 2232, and the third pin structure 2233 all extend along a first direction and protrude outward from the mounting groove 123 to connect with the power supply assembly. Corresponding pin clearance grooves 232 are provided on the inner wall of the heat insulation sleeve 23 to accommodate the first pin structure 2231, the second pin structure 2232, and the third pin structure 2233, respectively.
[0057] It should be noted that, Figures 10 to 12 The first pin structure 2231, the second pin structure 2232, and the third pin structure 2233 are all in an unbent state. In practical applications, the first pin structure 2231, the second pin structure 2232, and the third pin structure 2233 can be bent according to assembly requirements. Accordingly, such as Figure 8 In the example shown, a wire hole 125 can be made at the corresponding position of the mounting slot 123 to allow the aforementioned pin structure to pass through and be fixed.
[0058] In further embodiments of this application, such as Figure 4 , Figure 5 , Figure 8In the example, the support member 1 is a split structure, specifically including a support sleeve 11, a support base 12, and a fixing sleeve 13. The support sleeve 11 is arranged along a first direction, with one end forming an open end 112 and the other end detachably connected to the support base 12. The fixing sleeve 13 is connected to the open end 112 of the support sleeve 11 and is arranged through the first direction so that the aerosol generating rod 500 can pass through the fixing sleeve 13 and the open end 112 into the heating chamber 211. Multiple contact structures 131 are arranged circumferentially on the inner wall of the fixing sleeve 13 to abut against the aerosol generating rod 500, keeping the aerosol generating rod 500 stable and preventing it from falling off during use. The contact structures 131 can be made of a flexible material (such as silicone) to increase the friction when in contact with the aerosol generating rod 500. The support base 12 covers the support sleeve 11 in the first direction, forming the closed end 121 of the support member 1; the mounting groove 123 is located on the side of the support base 12 facing the open end 112 and abuts against the heating assembly 2; the side of the support base 12 facing away from the open end 112 has a connecting structure 124, which is used to connect the heating device 100 to the bracket structure of the atomizing device when the heating device 100 is assembled in the atomizing device, so as to fix the heating device 100. By setting the split support member 1, on the one hand, it is convenient to assemble and connect the heating assembly 2 and the heating device 100 as a whole, and on the other hand, it simplifies the structure of individual components and facilitates processing and manufacturing.
[0059] An embodiment of the second aspect of this application provides an atomizing device 400, such as... Figure 13 , Figure 14 and Figure 15 As shown, the atomizing device 400 includes a housing 410, a heating device 100 as described in any of the embodiments of the first aspect, and a power supply assembly 420. The housing 410 has an assembly port 411 at one end in a first direction, allowing the heating chamber 211 of the heating assembly 2 to communicate with the assembly port 411, enabling the aerosol generating rod 500 to be inserted into the heating chamber 211 of the heating assembly 2 through the assembly port 411. The power supply assembly 420 is electrically connected to the heating assembly 2 of the heating device 100, enabling it to supply power to the heating assembly 2 and cause the heating assembly to heat up, thereby heating the aerosol generating rod 500 inserted into the heating chamber 211.
[0060] The following describes a specific example of the atomizing device 400 of this application with reference to the accompanying drawings.
[0061] like Figures 1 to 15As shown, the atomizing device 400 is specifically a heat-not-burning device. The housing 410 is assembled from multiple sub-housings to facilitate the assembly of the various internal components. The top of the housing 410 has an assembly port 411. The housing 410 has a support structure 412 inside, which divides the internal space of the housing 410 into two different chambers. The heating device 100 is located in the chamber above the support structure 412, and the power supply component 420 is located in the chamber below the support structure 412.
[0062] like Figures 1 to 12 as well as Figure 15 In the example, the heating device 100 includes a support member 1 and a heating assembly 2. The support member 1 is made of PEEK material and includes a detachably connected support sleeve 11 and a support base 12. The support sleeve 11 is a hollow cylindrical structure with an open end 112 at the top, and a circumferentially extending pressure cap structure 113 on the inner wall of the open end 112. The pressure cap structure 113 has an elliptical second opening 1131. The support base 12 forms the closed end 121 of the support member 1, and the support base 12 has a mounting groove 123 on the side facing the open end 112. The mounting groove 123 extends into the support sleeve 11. The mounting groove 123 is an elliptical groove, and the inner side wall of the mounting groove 123 has a first step structure 1232 and a second step structure 1233 arranged sequentially from the inside to the outside. Multiple first protrusion structures 1231 of the same height are arranged circumferentially on the bottom wall of the mounting groove 123. The bottom surface of the support base 12 has multiple connecting structures 124, and the connecting structures 124 are connected to the corresponding snap-fit structures on the bracket structure 412 to form a snap-fit fixation.
[0063] The heating assembly 2 includes a nested heating tube 21 and a heat insulation sleeve 23, and a heating element 22 disposed between them. The heating tube 21 is an elliptical tube made of a high thermal conductivity alloy material (e.g., 430 stainless steel). The heating cavity 211 of the heating tube 21 has a major axis L2 of 8.5 mm, a minor axis L1 of 6.5 mm, and a wall thickness of 0.5 mm. The heating tube 21 is arranged along a first direction, and its bottom extends into the mounting groove 123 and abuts against the first step structure 1232. The heating element 22 is a mesh structure made of titanium metal and is attached to the outside of the heating tube 21. The mesh shape can be rhomboid, rectangular, circular, square, triangular, trapezoidal, or other shapes. The heat insulation sleeve 23 is made of a ceramic material with good heat insulation effect (e.g., white zirconium oxide) and has an elliptical sleeve structure adapted to the heating tube 21. The heat insulation sleeve 23 presses the heating element 22 tightly against the outer wall surface of the heating tube 21. The heating element 22 has a total length of 23.7 mm in the circumferential direction, a dimension of 14 mm in the first direction, and a thickness of 0.5 mm. The top of the heat insulation sleeve 23 has an elliptical first opening 231. In the first direction, the outer periphery of the first opening 231 abuts against the pressure cap structure 113, the inner periphery of the first opening 231 abuts against the top of the heating tube 21, and the bottom end of the heat insulation sleeve 23 abuts against the second step structure 1233 of the mounting groove 123.
[0064] Specifically, such as Figures 4 to 7 as well as Figures 10 to 12In the example shown, the heating element 22 includes a first sub-heating segment 221 and a second sub-heating segment 222. Both the first sub-heating segment 221 and the second sub-heating segment 222 extend circumferentially along the heating tube 21, and in a second direction, the first sub-heating segment 221 and the second sub-heating segment 222 are located on opposite sides of the heating tube 21. In a first direction, the first sub-heating segment 221 and the second sub-heating segment 222 are staggered, with the first sub-heating segment 221 protruding relative to the second sub-heating segment 222 toward the opening end 112, and the first sub-heating segment 221 and the second sub-heating segment 222 have a certain overlapping area in the second direction. In the circumferential direction, one end of the first sub-heating segment 221 has a first pin structure 2231, and the end of the second sub-heating segment 222 near the first pin structure 2231 in the circumferential direction has a second pin structure 2232. There is a certain gap between the first pin structure 2231 and the second pin structure 2232. The end of the first sub-heating segment 221 away from the first pin structure 2231 is connected to the end of the second sub-heating segment 222 away from the second pin structure 2232, and a third pin structure 2233 is provided at the connection point. The first sub-heating segment 221 and the second sub-heating segment 222 are connected in parallel through the first pin structure 2231, the second pin structure 2232 and the third pin structure 2233. The first pin structure 2231, the second pin structure 2232 and the third pin structure 2233 all extend along the first direction and protrude outward from the mounting groove 123 to form an electrical connection with the power supply component 420. When the first pin structure 2231 and the third pin structure 2233 are energized, the first sub-heating segment 221 is energized and heats up; when the second pin structure 2232 and the third pin structure 2233 are energized, the second sub-heating segment 222 is energized and heats up; when the first pin structure 2231, the second pin structure 2232 and the third pin structure 2233 are energized simultaneously, the first sub-heating segment 221 and the second sub-heating segment 222 are energized and heats up simultaneously.
[0065] like Figure 15 In the example, the power supply assembly 420 includes a battery 421 and an electronic control board 422 that are electrically connected, the electronic control board 422 being used to control the power supply state of the battery 421 to the heating element 22.
[0066] like Figures 1 to 6 as well as Figures 13 to 15In the example, when the aerosol generating rod 500 is inserted into the heating chamber 211 of the heating device 100 through the assembly port 411, the end face of the aerosol generating rod 500 abuts against the first protrusion 1231 in the mounting groove 123, and a certain distance is maintained between the end face and the bottom wall of the mounting groove 123. The diameter of the aerosol generating rod 500 is larger than the minor axis L1 and smaller than the major axis L2 of the heating chamber 211. The portion of the aerosol generating rod 500 inserted into the heating chamber 211 forms a certain amount of compression (approximately 15% to 30%) in the second direction, while in the third direction, an air inlet gap 212 is formed between the aerosol generating rod 500 and the inner wall of the heating chamber 211. When the user performs a suction action through the suction end of the aerosol generating rod 500, external air enters the heating chamber 211 through the air inlet gap 212 and enters the mounting groove 123 along the first direction, and is then drawn into the interior of the aerosol generating rod 500.
[0067] At the same time, the power supply component 420 controls the battery 421 to supply power to the heating element 22, so that the heating element 22 generates heat, which is conducted to the interior of the aerosol generating rod 500 through the heating tube 21, so that the atomizing matrix therein is heated and atomized to generate aerosol. The aerosol mixes with the airflow entering the interior of the aerosol generating rod 500 and flows to the suction end with the airflow.
[0068] Specifically, when heating the aerosol generating rod 500, an appropriate heating method can be adopted. For example, at the beginning of heating, the first sub-heating section 221 can be controlled to heat up independently to achieve preheating. After a first preset time, the second sub-heating section 222 is started, and the temperature of the second sub-heating section 222 rises while the heating temperature of the first sub-heating section 221 decreases until the temperatures of the first sub-heating section 221 and the second sub-heating section 222 are consistent, and the current heating temperature is maintained for continuous heating.
[0069] The heating control method described above ensures that the mixed gas flowing from the suction end of the aerosol generating rod 500 meets the user's needs. By employing a heating component 2 with an elliptical heating chamber 211, the inserted portion of the aerosol generating rod 500 can be compressed in the second direction when inserted into the heating chamber 211, thereby reducing the width of the aerosol generating rod 500 in that direction. This shortens the time required to heat the internal atomizing matrix and generate aerosol in that direction, reducing energy consumption, improving heating efficiency, and also shortening user waiting time, thus improving the user experience.
[0070] Furthermore, the atomizing device 400 in this embodiment also has all the beneficial effects of the heating device 100 in any of the above embodiments, which will not be repeated here.
[0071] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
