[0002] Currently, in common non-combustion heating atomizing devices, an aerosol-generating rod is inserted into a heating cavity and heated, so that the atomizing substrate stored in the aerosol-generating rod absorbs heat and atomizes. However, the atomizing substrate is usually concentrated in a region near the bottom of the support member for mounting the heating assembly, and the heating area of the heating assembly is large, so that it covers up to the region near the top of the support member of the aerosol-generating rod, which causes part of heat to be lost during heating, resulting in low heating efficiency. Furthermore, the temperature at the top of the support member becomes too high, which may lead to a reduction in service life. [Summary of the Invention]

[0018] Hereinafter, the present application will be described in further detail through specific embodiments with reference to the drawings. Similar components in different embodiments share corresponding similar component numbers. In the following detailed description, numerous details are set forth to facilitate a better understanding of the present application. However, those skilled in the art can readily recognize that some features may be omitted in different circumstances, or may be replaced by other components, materials and methods. In some cases, certain operations related to the present application are not shown or described herein to avoid obscuring the core aspects of the present application with excessive description, but those skilled in the art do not need a detailed description of these related operations, and can fully grasp the related operations based on the description in the specification and general knowledge in the art.

[0019] In addition, the features, operations or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the order of operation steps related to each embodiment can also be reordered and adjusted in a manner obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing the embodiments, and are not intended to imply essential configurations and / or orders.

[0020] As in the cases of "first", "second" and the like, the numbering of components herein is only used to distinguish the described objects per se, and does not have any order or technical meaning. Unless otherwise specifically stated, the terms "connection" and "coupling" described in the present application both include direct and indirect connection (coupling).

[0021] An aerosol-generating rod is a special atomized product containing an atomizable substrate inside. When in use, it is inserted into a matching non-combustion heating type atomization device, and a heating assembly is used to heat the aerosol-generating rod to atomize the atomizable substrate inside the aerosol-generating rod to generate aerosol, and as the user sucks the aerosol-generating rod, the aerosol moves to the suction end along with the airflow.

[0022] In the heating device according to this application, a heating assembly having a heating cavity is arranged inside a support member. The heating cavity can accommodate an aerosol generating rod and, when energized, generates heat to heat the aerosol generating rod inserted into the heating cavity. By providing a vent at the closed end of the mounting cavity and an intake port between the insertion end of the mounting cavity and the end face of the heating assembly that abuts the insertion end, the intake port and the mounting cavity are in communication. When the user performs a suction operation on the aerosol generating rod, the external airflow flows in from the insertion port at the insertion end, passes through the intake port into the mounting cavity, and further flows into the heating cavity from the vent at the closed end, allowing it to be drawn into the interior of the aerosol generating rod. Because the ambient temperature is low, some of the heat from the heating assembly is absorbed as it passes through the insertion end and the mounting cavity, and the absorbed heat can be carried into the heating cavity. As a result, the temperature of the region of the heating assembly near the insertion end is relatively lowered, energy recovery becomes possible, energy consumption in the heating process is reduced, and heating efficiency is improved. Here, the first direction is the height direction of the atomizing device, and the situation in the following embodiments is the same.

[0023] Hereinafter, several embodiments of the heating device and atomizing device according to this application will be described with reference to the drawings.

[0024] A first embodiment of this application provides a heating device 100. As shown in Figures 1, 2, and 3, the heating device 100 comprises a support member 1 and a heating assembly 2. A mounting cavity 11 is provided inside the support member 1, and the heating assembly 2 is placed inside the mounting cavity 11 to be mounted and fixed via the support member 1 when used in an atomizing device. In a first direction, the mounting cavity 11 of the support member 1 has a closed end 13 at one end and an insertion end 12 at the other end, and the insertion end 12 is provided with an insertion port 121 for passing an aerosol generating rod through. The heating assembly 2 has a heating cavity 21 capable of accommodating an aerosol generating rod, and in a first direction, one end of the heating assembly 2 abuts against the insertion end 12 of the support member 1, thereby allowing the heating cavity 21 to communicate with the outside atmosphere through the insertion port 121 of the insertion end 12, and allowing the aerosol generating rod to pass through the insertion port 121 and be inserted into the heating cavity 21. One end of the heating assembly 2, away from the insertion end 12, has a ventilation hole 221 that connects the heating cavity 21 and the mounting cavity 11. The end face of the heating assembly 2 that is in contact with the insertion end 12 of the support member 1 has an air intake port 122 that communicates with the mounting cavity 11.

[0025] During use, one end of the aerosol generating rod 500 is inserted into the heating cavity 21 through the inlet 121. When the user performs a suction action on the aerosol generating rod 500, the external airflow flows into the mounting cavity 11, passing sequentially through the inlet 121 and the intake port 122. It then flows along the first direction to the end of the heating assembly 2 away from the inlet 121, and further through the vent hole 221 into the heating cavity 21, where it is drawn into the interior of the aerosol generating rod 500 from its end. Simultaneously, the heating assembly 2 heats the portion of the aerosol generating rod 500 inserted into the heating cavity 21. As a result, the atomizing substrate stored inside the aerosol generating rod 500 receives heat and atomizes, moving to the other end of the aerosol generating rod 500 with the airflow.

[0026] Here, because the ambient temperature is relatively low, some of the heat from the area near the insertion end 12 of the heating assembly 2 can be absorbed as it passes through the intake port 122 and the mounting cavity 11 and carried into the heating cavity 21, where it can be used to heat the aerosol generating rod 500, thereby enabling energy recovery and lowering the temperature of the insertion end 12.

[0027] To understand this, a typical aerosol generating rod has a cylindrical structure, and the atomizing substrate is usually stored near the bottom end inside the aerosol generating rod (i.e., the end that enters the heating cavity). In practical use, the region where the atomizing substrate is stored inside the aerosol generating rod needs to be heated, but the heat demand near the insertion end of the support member is not large. Conventional heating assemblies generally have a large covering area, resulting in energy loss due to heating near the insertion end, and the insertion end is susceptible to high temperatures, making it prone to degradation and affecting its service life.

[0028] In this embodiment, the heating device 100, through structural improvements and optimizations, allows external airflow to enter the inlet 121 and then enter the mounting cavity 11 via the intake port 122. As it flows to the heating cavity 21, some of the heat is recovered to heat the aerosol generating rod. This is advantageous in reducing energy consumption, improving heating efficiency, and lowering the temperature of the insertion end 12 of the support member 1, thereby extending its service life.

[0029] Furthermore, the shape and size of the inlet 121 are suitable for the aerosol generating rod 500, and when the aerosol generating rod 500 is inserted into the heating cavity 21 through the inlet 121, a certain gap is still maintained between the inner edge of the inlet 121 and the aerosol generating rod 500, allowing outside air to flow in.

[0030] In further embodiments of this application, as shown in Figures 1 to 5, the heating assembly 2 includes a heating base 22 connected to a support member 1, and a heating tube 23 arranged along a first direction. The heating tube 23 is clamped and fixed via the heating base 22 and the support member 1, with one end in contact with the heating base 22 and the other end in contact with the insertion end 12 of the support member 1. The heating tube 23 and the heating base 22 surround each other to form a heating cavity 21, the heating base 22 is provided with a ventilation hole 221, and the heating cavity 21 and the mounting cavity 11 are in communication via the ventilation hole 221. The end of the insertion end 12 of the support member 1 facing the heating tube 23 has a plurality of first projection structures 123, which are spaced apart along the circumferential direction of the mounting cavity 11, and in the first direction, each first projection structure 123 abuts against the end face of the heating tube 23, and in the circumferential direction, the space between any two adjacent first projection structures 123 forms a single air intake port 122. That is, a plurality of air intake ports 122 are formed spaced apart in the circumferential direction. By the first projection structures 123 abutting against the end face of the heating tube 23 to form the air intake ports 122, the external airflow can come into contact with the heating tube 23, the first projection structures 123 and the insertion end 12 as it passes through the air intake ports 122, allowing the airflow to absorb heat from the area where the insertion end is located, lowering the temperature of that area, and bringing the heat absorbed by the airflow into the heating cavity 21. Here, the circumferential dimensions of the first projection structure 123 can be set according to the actual usage needs. Preferably, multiple first projection structures 123 are provided at equal intervals in the circumferential direction, so that the airflow can pass through multiple intake ports 122 and flow relatively uniformly into the mounting cavity 11. This allows heat released to the outside of the heating assembly 2 in different circumferential regions to be absorbed, resulting in higher recovery efficiency.

[0031] In further embodiments of this application, as shown in Figures 3 to 6, one end of the insertion end 12 of the support member 1 facing the heating tube 23 has a first mounting groove 124, the first mounting groove 124 is provided on the outside of the first projection structure 123 and extends along a first direction. One end of the heating tube 23 toward the insertion end 12 extends into the first mounting groove 124, and a plurality of second projection structures 125 are provided within the first mounting groove 124, the plurality of second projection structures 125 are provided at intervals along the circumferential direction and abut against the outer wall of the heating tube 23, performing a positioning function relative to the heating tube 23. Here, in the circumferential direction of the first mounting groove 124, each intake port 122 corresponds to a gap space formed between two adjacent second projection structures 125, thereby allowing the external airflow to pass through the intake port 122 and then flow into the mounting cavity 11 from the gap space formed between the second projection structures 125. Since the airflow needs to change direction after passing through the intake port 122, providing the second projection structure 125 here is advantageous in that the airflows flowing in from different intake ports 122 maintain an independent state from each other during the process of changing direction, preventing interference with each other and improving the stability of the airflow motion.

[0032] Furthermore, as shown in Figures 4 to 6, the second projection structure 125 is provided at a position corresponding to the first projection structure 123, and in the first direction, the corresponding second projection structure 125 and the first projection structure 123 are connected to each other, forming a continuous flow guide passage. This avoids the formation of gaps between the two and facilitates processing and molding. In the circumferential direction of the first mounting groove 124, the size of the second projection structure 125 is less than or equal to the size of the corresponding first projection structure 123. This ensures that when the airflow enters the gap space formed between the intake port 122 and the second projection structure 125, the airflow is not blocked, the flow path area is not reduced, and the airflow flows stably and smoothly into the mounting cavity 11. Preferably, as shown in Figure 8, the circumferential dimensions of the second projection structure 125 are smaller than the dimensions of the first projection structure 123. This further expands the airflow passage, which is advantageous in slowing the airflow velocity and improving the stability of the airflow motion.

[0033] Furthermore, as shown in Figures 4 to 6, the first mounting groove 124 is a circular groove structure that fits the heating tube 23, and the flow area of ​​the intake port 122 gradually increases in the direction away from the insertion end 12 along the first direction, further increasing the intake airflow rate. Here, as shown in Figure 7, the cross-sectional shape of the intake port 122 may be set to a trapezoid, or of course, to an arc shape, thereby gradually increasing the flow area of ​​the intake port 122 as the airflow flows from the insertion end 12 to the mounting cavity 11.

[0034] Furthermore, in one specific example, as shown in Figures 5 and 6, the diameter of the inlet 121 is larger than the inner diameter of the heating tube 23. As a result, when the aerosol passes through the inlet 121 and is inserted into the heating cavity 21, the side wall of the aerosol generating rod 500 does not come into contact with the inner wall defining the inlet 121. This ensures that the intake passage is not blocked, and the aerosol generating rod 500 can pass the external airflow at any position in the circumferential direction, which is advantageous for uniformly supplying the intake airflow to the mounting cavity 11.

[0035] Furthermore, in another specific example, as shown in Figure 7, the diameter of at least a portion of the inlet 121 may gradually increase from the inside to the outside in the first direction. In this configuration, the inlet 121 can act as a guide when the aerosol generating rod 500 passes through it, while when the aerosol generating rod 500 is inserted into the heating cavity 21, the external airflow can flow in through the gap formed between the inlet 121 and the aerosol generating rod 500, thereby increasing the opening area on the intake side. In the region where the diameter of the inlet 121 increases, the cross-sectional shape may be a slope, forming a structure similar to a chamfer, or the cross-sectional shape may be a curved surface, resulting in a rounded structure.

[0036] In a further embodiment of this application, as shown in Figure 8, a flange structure 222 is provided on the outer wall of the heating base 22. The flange structure 222 extends circumferentially and abuts against the inner wall of the support member 1. The flange structure 222 divides the mounting cavity 11 into an intake section 111 and an air guide section 112. The air guide section 112 is located on the side facing the closed end 13 of the flange structure 222 and communicates with the heating cavity 21 via a vent hole 221. The intake section 111 is located on the side facing the insertion end 12 of the flange structure 222 and communicates with an intake port 122. Here, an air guide passage 223 is provided in the flange structure 222. The air guide passage 223 connects the intake section 111 and the air guide section 112. Gas flowing into the intake section 111 from the intake port 122 can enter the air guide section 112 through the air guide passage 223 and then enter the heating cavity 21 through the vent hole 221. By forming a contact engagement structure between the flange structure 222 and the support member 1, the heating base 22 and the heating tube 23 are fixed in the radial direction, ensuring the precise positioning of the heating tube 23, and allowing airflow to pass through the air guide passage 223.

[0037] In actual use, the flange structure 222 may be a continuous structure extending along the circumferential direction, as shown in Figure 8. Naturally, multiple flange structures 222 may be provided at intervals in the circumferential direction so as to utilize the gaps formed between adjacent flange structures 222 to form an air passage 223.

[0038] Furthermore, as shown in Figures 7, 8, and 9, the heating device 100 further comprises a base sealing member 31 and an airflow sensor 32. The base sealing member 31 is located inside the support member 1 and on the side of the heating base 22 away from the heating tube 23. The base sealing member 31 is sealed and connected to the flange structure 222 of the heating base 22 and the inner wall of the support member 1. The base sealing member 31 has a flexible membrane structure 311, which is located, for example, opposite the closed end 13 on the base sealing member 31 shown in Figure 9. The flexible membrane structure 311 and the heating base 22 together surround the flexible membrane structure 311 to form an air conductor 112. The flexible membrane structure 311 has a certain degree of flexibility, and when there is a change in air pressure due to the movement of airflow in the air conductor 112, the flexible membrane structure 311 can be deformed by the air pressure. For example, when a user performs a suction operation on the aerosol generating rod 500, the airflow in the air conductor 112 is drawn into the heating cavity 21, creating negative pressure in the air conductor 112. The flexible membrane structure 311 deforms under the effect of the negative pressure and moves toward the heating base 22, thereby generating airflow motion on the other side of the flexible membrane structure 311 away from the heating base 22.

[0039] Correspondingly, as shown in Figure 9, the airflow sensor 32 is positioned within the support member 1 and on the side of the flexible membrane structure 311 away from the heating base 22, and is configured to sense airflow motion. When the flexible membrane structure 311 deforms, airflow motion occurs on the side of the flexible membrane structure 311 away from the heating base 22, and the airflow sensor 32 senses this airflow motion and generates a detection signal. When applied to atomizing equipment, the airflow sensor 32 is configured to communicate with the power supply assembly 420 and transmit the detection signal to the power supply assembly 420, which can then control the power supply state to the heating assembly 2 based on the detection signal.

[0040] In a further embodiment of this application, as shown in Figure 8, the support member 1 is a separable structure including a first support subsegment 141 and a second support subsegment 142. The first support subsegment 141 and the second support subsegment 142 are arranged sequentially in a first direction and are detachably connected. One end of the first support subsegment 141 away from the second support subsegment 142 forms an insertion end 12, and the other end of the second support subsegment 142 away from the first support subsegment 141 forms a closed end 13. During the manufacturing process, the heating assembly 2 can be assembled by first mounting it in the mounting cavity 11, and then connecting the first support subsegment 141 and the second support subsegment 142, making attachment and detachment easy. In this case, the outer end surface of the closed end 13 of the second support subsegment 142 has a connecting structure 131, and when the second support subsegment 142 is attached to the atomizing equipment, it is connected and fixed to the support structure inside the atomizing equipment via the connecting structure 131, thereby enabling the connection and assembly of the heating device 100 and the atomizing equipment.

[0041] In a further embodiment of this application, as shown in Figure 9, the heating device 100 further comprises a fixing sleeve 34 positioned at the insertion end 12 of the support member 1 and connected to the support member 1. The fixing sleeve 34 has a structure that penetrates along a first direction and is positioned corresponding to the insertion opening 121 of the support member 1. The inner wall of the fixing sleeve 34 has a contact structure 341, and when the aerosol generating rod 500 is inserted into the fixing sleeve 34, the contact structure 341 can form a contact engagement with the side wall of the aerosol generating rod 500 and serve to fix the aerosol generating rod 500. The contact structures 341 may be spaced apart along the circumferential direction, and gas can flow between adjacent contact structures 341. Preferably, the contact structures 341 employ a flexible structure such as a silica gel structure, which can increase the frictional force with the contact surface of the aerosol generating rod 500 and prevent the aerosol generating rod 500 from unexpectedly falling out during use. Furthermore, the entire fixing sleeve 34 employs a silicone structure, and when assembled with the housing of the atomizing equipment, the end face of the fixing sleeve 34 abuts against the housing, thereby achieving secure assembly.

[0042] A second embodiment of this application provides an atomizing device 400. As shown in Figures 10, 11, 12, and 13, the atomizing device 400 comprises a housing 410, a heating device 100 in any embodiment of the first embodiment described above, and a power supply assembly 420. One end of the housing 410 in a first direction has a mounting port 411. For example, the top end of the housing 410 shown in Figure 12 is provided with a mounting port 411. Both the heating device 100 and the power supply assembly 420 are located inside the housing 410. The insertion port 121 of the heating device 100 is provided at a position corresponding to the mounting port 411 so that the heating cavity 21 of the heating assembly 2 and the mounting port 411 are in communication, and the aerosol generating rod 500 can be inserted into the heating cavity 21 of the heating assembly 2 from the mounting port 411. The power supply assembly 420 is electrically connected to the heating assembly 2 of the heating device 100 and can supply power to the heating assembly 2 to heat the heating tube, thereby heating the aerosol generating rod 500 inserted into the heating cavity 21.

[0043] Here, as shown in Figures 5 and 13, a ventilation hole 221 is provided at one end of the heating assembly 2 away from the insertion end 12 of the support member 1. An air intake port 122 communicating with the mounting cavity 11 is provided between the insertion end 12 of the support member 1 and the end face of the heating assembly 2 that abuts it. When the aerosol generating rod 500 is inserted into the heating cavity 21 from the mounting port 411, an external airflow can flow in through the gap formed between the mounting port 411 and the aerosol generating rod 500, pass through the air intake port 122 on the support member 1, and enter the mounting cavity 11 (i.e., the cavity between the support member 1 and the heating assembly 2). The low-temperature airflow can cool the insertion end 12 of the support member 1, absorb some of the heat released from the heating assembly 2, and bring the absorbed heat into the heating cavity 21 to heat the aerosol generating rod 500, thereby achieving energy recovery and localized cooling.

[0044] A specific example of the atomizing device 400 of this application will be described below with reference to the drawings.

[0045] As shown in Figures 1 and 10 to 13, the atomizing device 400 is specifically a non-combustion heating device, and the housing 410 is constructed by assembling multiple sub-housings to facilitate the assembly of the internal components. A mounting opening 411 is provided at the top of the housing 410, and the inside of the housing 410 has a support structure 412, which divides the internal space of the housing 410 into two different cavities. The heating device 100 is located in the cavity above the support structure 412, and the power supply assembly 420 is located in the cavity below the support structure 412.

[0046] As shown in Figures 1, 5, 11, 12, and 13, the heating device 100 comprises a support member 1, a heating assembly 2, a base sealing member 31, an airflow sensor 32, and a fixing sleeve 34.

[0047] Specifically, the support member 1 is a hollow cylindrical structure with an internal mounting cavity 11. The first support subsegment 141 is located above the second support subsegment 142. The tip of the first support subsegment 141 is an insertion end 12 with a circular insertion opening 121. The bottom of the second support subsegment 142 is a closed end 13. The outer end surface of the closed end 13 has a connecting structure 131, and the second support subsegment 142 is fixed to the support structure 412 via the connecting structure 131. The fixing sleeve 34 is connected to the top of the first support subsegment 141 and is positioned to communicate with the insertion opening 121 and the mounting opening 411. The fixing sleeve 34 engages with and is fixed to the housing 410 and the first support subsegment 141, respectively. The inner wall of the fixing sleeve 34 is provided with a plurality of contact structures 341 made of silica gel material, spaced apart along the circumferential direction.

[0048] The base sealing member 31 is positioned at the connection point between the first support subsegment 141 and the second support subsegment 142. One end of the base sealing member 31 facing the first support subsegment has a first slot 312, and the other end facing the second support subsegment has a second slot 313, which is inserted into the second support subsegment 142 and fitted to seal against the inner wall of the second support subsegment 142. The one end of the first support subsegment 141 facing the second support subsegment 142 is inserted into the first slot 312 and fitted to seal against the inner wall of the first slot 312. A sensor holder 33 made of silica gel is further positioned in the second slot 313, and the sensor holder 33 has an opening, to which the airflow sensor is fixed. The position of the base sealing member 31 corresponding to the sensor has a flexible membrane structure 311.

[0049] The heating base 22 of the heating assembly 2 is located close to the base sealing member 31 within the first support subsegment 141 and is engaged with the base sealing member 31. The heating base 22 has a hollow structure with a through-hole at the top, and multiple ventilation holes 221 are provided in the bottom wall. A second mounting groove 224 is provided at the top end of the heating base 22. The bottom end of the heating tube 23 is inserted into the second mounting groove 224 of the heating base 22 to form a contact state, and the internal space of the heating tube 23 and the internal space of the heating base 22 together form a heating cavity 21. The outer wall of the heating base 22 has a circular flange structure 222, which is sealed and engaged with the inner wall of the first support subsegment 141, dividing the mounting cavity 11 into an intake cavity and an intake cavity, and the flange structure 222 is provided with an air passage 223 that connects the intake cavity and the intake cavity, and the base sealing member 31 has an air passage structure corresponding to the air passage 223.

[0050] A first mounting groove 124 is provided at the inner end of the insertion end 12. The bottom wall of the first mounting groove 124 has a plurality of first projection structures 123 spaced apart along the circumferential direction, and a plurality of second projection structures 125 spaced apart along the circumferential direction are provided inside the first mounting groove 124. The top end of the heating tube 23 is inserted into the first mounting groove 124 and abuts against the plurality of first projection structures 123, and the outer wall of the heating tube 23 abuts against the plurality of second projection structures 125. In the circumferential direction, the gap space formed between any two adjacent first projection structures 123 forms a single air intake port 122, and the second projection structures 125 are provided at positions corresponding to the first projection structures 123 and are connected to the corresponding first projection structures 123 in the first direction. Here, in the circumferential direction, the size of the second projection structure 125 is smaller than the size of the first projection structure 123, and the flow area of ​​the intake port 122 gradually increases in the direction toward the closed end 13 along the first direction. Also, the diameter of the inlet 121 of the insertion end 12 is larger than the inner diameter of the heating tube 23, and in the first direction, the diameter of the upper region of the inlet 121 gradually increases from the inside to the outside.

[0051] The power supply assembly 420 includes a battery 421 and an electrical control board 422, the electrical control board 422 having a control circuit and being electrically connected to the battery 421 and the heating tube 23 of the heating assembly 2, and at the same time, the electrical control board 422 is communicatively connected to the airflow sensor 32 and controls the state of power supply to the heating tube 23.

[0052] When the aerosol generating rod 500 is inserted into the heating cavity 21 through the mounting opening 411, the contact structure 341 of the fixing sleeve 34 abuts against the outer wall of the aerosol generating rod 500, serving to position and fix it to the aerosol generating rod 500. When the user performs a suction operation on the aerosol generating rod 500, negative pressure is generated in the air conductor cavity, causing the flexible membrane structure 311 to deform. The flexible membrane structure 311 causes the airflow on one side of the airflow sensor 32 to move, and the airflow sensor 32 generates a detection signal. Based on the detection signal, the electrical control board 422 controls the battery 421 to supply power to the heating tube 23, causing the heating tube 23 to heat up. As a result, the aerosol generating rod 500 is heated, and the atomizing substrate inside it receives the heat and atomizes, generating an aerosol. The region of the aerosol generation rod 500 that stores the atomizing substrate is located near the bottom of the heating cavity 21. The external airflow passes through the mounting port 411 and the insertion port 121, then enters the intake section 111 of the mounting cavity 11 through multiple intake ports 122 at the top of the heating tube 23, flows along the first direction to the guide section 112, and further enters the heating cavity 21 through the vent hole 221, is drawn into the aerosol generation rod 500, and carries the formed aerosol to the suction end. By exchanging heat with the lower temperature intake airflow, some heat is absorbed from the insertion end 12 and the top of the heating tube 23, lowering the temperature of the insertion end 12 and extending its service life. Furthermore, the airflow carries the absorbed heat into the heating cavity 21 and is used to heat the aerosol generation rod 500, thereby achieving energy recycling, which is advantageous for reducing energy consumption and improving heating efficiency.

[0053] Furthermore, the atomizing device 400 in this embodiment also possesses all the beneficial effects of the heating device 100 in any of the above embodiments, and such effects will not be described here.

A person skilled in the art to which this application belongs can perform several simple deductions, modifications, or substitutions based on the idea of ​​this application.
