[0002] Non-combustion heating devices typically include an atomizing and heating assembly having a storage cavity, in which the aerosol product is inserted and the atomizing and heating assembly comes into contact with the aerosol product to heat the aerosol product in a direct contact manner to generate an aerosol.

[0003] In order to improve the heating uniformity of the aerosol product, the prior art uses a hot air flow to heat the aerosol product, where external cold air enters the non-combustion heating device through an air intake, is heated by an atomizing and heating assembly, and then forms a hot air flow. The hot air flow enters the aerosol product through the bottom of the containing cavity, heats the aerosol product, and then generates an aerosol and flows out through the aerosol outlet. The atomizing and heating assembly is often attached to the bottom of the aerosol product, and the heat from the atomizing and heating assembly is transferred upward or downward along the non-combustion heating device. However, most of the heat transferred downward cannot be used by the aerosol product, resulting in a large heat loss in the non-combustion heating device. Summary of the Invention

However, those skilled in the art will be able to fully understand the relevant operations based on the description in the specification and general knowledge in the art without the need for detailed description of these related operations.

[0028] Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments, and the operational steps of each embodiment may be reordered or adjusted in a manner that would be obvious to one skilled in the art. Therefore, the specification and drawings are intended only to clearly explain the embodiments and do not imply any required configuration and / or order.

[0029] The numbering of parts in this specification, such as "first", "second", etc., is only used to distinguish the objects described and does not have any sequential or technical meaning. "Connected" and "coupled" as used in this application include both direct and indirect connections (couplings) unless otherwise stated.

[0030] Embodiments of the present application disclose an atomizing and heating assembly 200 adapted for use in non-combustion heating devices, for containing an aerosol product 40 and for heating the aerosol product 40 to generate an aerosol.

[0031] 2 to 10, 14 to 16, and 19, the atomizing and heating assembly 200 according to the embodiment of the present application includes a heating barrel 21 having one open end and the other closed end. The heating barrel 21 has a generally cylindrical structure and includes a bottom wall 212 and a side wall 211. The bottom wall 212 and the side wall 211 of the heating barrel 21 form a surrounding cavity for accommodating an aerosol product 40. The aerosol product 40 can be inserted into the accommodating cavity from the open end 214 of the heating barrel 21, thereby attaching the aerosol product 40 to the atomizing and heating assembly 200.

[0032] In some embodiments, referring to Figures 3, 4, 16, and 19, an atomization heating assembly 200 includes a mounting base 11. A heating barrel 21 is suspended within the mounting base 11. An open end 214 of the heating barrel 21 is provided with an outer flange 213 connected to the side wall 211 of the heating barrel 21. The outer flange 213 extends radially outward of the heating barrel 21 to form a radial outer flange. The outer flange may be a continuous structure extending along the circumferential direction, or may be a discontinuous structure in the circumferential direction. That is, the outer flange 213 of the heating barrel 21 includes a plurality of outwardly protruding structures spaced apart in the circumferential direction, and the outer flange 213 of the heating barrel 21 abuts against the mounting base 11 in the axial direction of the heating barrel 21, thereby fixing the position of the heating barrel 21 on the mounting base 11.

[0033] In one embodiment, the heat insulating cylinder 14 is provided so that both ends in the axial direction are open, with the opening at one end sealed by a plug 15 and the opening at the other end sealingly engaged with the sealing member 12. In another embodiment, the heat insulating cylinder 14 may be provided so that one axial end is open and the other end is sealed, with the open end 214 of the heat insulating cylinder 14 and the sealing member 12 sealingly engaged.

[0034] The heating barrel 21 is located within the thermal insulation barrel 14 and is arranged coaxially with the thermal insulation barrel 14. The bottom wall 212 of the heating barrel 21 and the plug 15 are arranged at a distance from each other in the axial direction of the heating barrel 21, and the side wall 211 of the heating barrel 21 is further arranged at a distance from the wall of the thermal insulation barrel 14. This direct contact between the heating barrel 21 and the thermal insulation barrel 14 reduces heat transfer to the thermal insulation barrel 14. The sealing member 12 is provided with a communication channel 121 arranged coaxially with the thermal insulation barrel 14, which communicates with the storage cavity, so that the aerosol product 40 can be inserted into the storage cavity through the communication channel 121.

[0035] In one embodiment, as shown in Figures 3, 4, 16, and 19, a support portion extending into the heat insulating barrel 14 is disposed on the wall of the heat insulating barrel 14. The support portion may include a support arm 141, one end of which is connected to the wall of the heat insulating barrel 14 and the other end of which is suspended within the heat insulating barrel 14, and the support arm 141 has a ring shape. The outer flange 213 of the heating barrel 21 is supported by the support arm 141, or the support arm 141 has a circumferentially discontinuous structure. That is, the support arm 141 includes a plurality of support structures spaced apart in the circumferential direction and matches a plurality of outwardly protruding structures spaced apart in the circumferential direction of the outer flange 213. The sealing member 12 has a portion that extends into the thermal insulation barrel 14, and can abut against the outer flange 213 in the axial direction of the heating barrel 21. In this way, the heating barrel 21 is clamped and fixed within the thermal insulation barrel 14 by the support arm 141 and the sealing member 12, thereby fixing the position of the heating barrel 21 within the thermal insulation barrel 14, and the sealing member 12 abuts against the outer flange 213 in the axial direction of the heating barrel 21, thereby sealing the sealing member 12 and the heating barrel 21. In this way, the heating barrel 21 is suspended within the thermal insulation barrel 14, reducing the contact area between the heating barrel 21 and the thermal insulation barrel 14 and causing the bottom wall 212 of the heating barrel 21 to move away from the accommodating cavity, thereby reducing the amount of heat transferred to the bottom of the atomization heating assembly 200 or the entire non-combustion heating device. This reduces heat loss and contributes to improving the heat utilization rate of the non-combustion heating device.

[0036] Of course, in other embodiments, the mounting base 11 does not have the insulating barrel 14 and the sealing member 12, and the entire non-combustion heating device includes a device body 100, which includes a housing 101, which has a mounting cavity, the heating barrel 21 in the atomization heating assembly 200 is located within the mounting cavity, the bottom wall 212 and the side wall 211 of the heating barrel 21 are both spaced apart from the housing 101, the housing 101 is provided with a support arm extending into the mounting cavity, and the outer surface of the side wall 211 of the heating barrel 21 is provided with a constricted portion, and the support arm and the constricted portion cooperate to hang and fix the heating barrel 21 within the housing 101, and in this way too, the amount of heat transferred by the heating barrel 21 away from the accommodating cavity to the bottom of the non-combustion heating device due to direct contact is reduced, heat loss is reduced, and this contributes to improving the heat utilization rate of the non-combustion heating device.

[0037] 3 , 4 , 7 , 16 , and 19 , in some embodiments, the barrel 21 cooperates with the mounting base 11 via an outer flange 213 so that the barrel 21 is mounted within the mounting base 11. The atomization heating assembly 200 further includes a reflective heat insulating layer 34. The reflective heat insulating layer 34 is disposed between the mounting base 11 and the barrel 21 and surrounds the outer surface of the barrel 21. When the barrel 21 heats the aerosol product 40, the reflective heat insulating layer 34 reflects the thermal radiation of the barrel 21 and prevents the heat generated by the barrel 21 from being conducted to the mounting base 11. The reflective heat insulating layer 34 does not accumulate heat itself, has a high thermal insulation effect, is low cost, and occupies a small space.

[0038] Specifically, in an embodiment in which the mounting base 11 includes a sealing member 12, a heat insulating cylinder 14, and a plug 15, the sealing member 12, the heat insulating cylinder 14, and the plug 15 surround and form a cavity, or in other embodiments, the sealing member 12 and the heat insulating cylinder 14 surround and form a cavity, the heating cylinder 21 is located within the cavity, and the inner surface of the cavity forms the inner surface of the mounting base 11, and a gap is left between the barrel wall of the heating cylinder 21 and the cavity wall of the cavity, thereby satisfying the requirement that the entire heating cylinder 21 is suspended from the mounting base 11.

[0039] The gap width between the cylinder wall of the heating cylinder 21 and the cavity wall of the cavity is 0.3 mm or more. Specifically, the gap between the side wall 211 of the heating cylinder 21 and the cylinder wall of the heat insulating cylinder 14 may be 0.3 mm or more, such as 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm.

[0040] The heating barrel 21 and the mounting base 11 surround each other to form an insulating cavity 33 surrounding the heating barrel 21. The reflective insulating layer 34 is located within the insulating cavity 33 and may be provided on the cavity wall of the insulating cavity 33; for example, it may be applied to the outer peripheral surface of the heating barrel 21 or on the inner surface of the mounting base 11. That is, the reflective insulating layer 34 may be applied to the inner surface of the insulating barrel 14 and the end surface of the plug 15 facing the insulating cavity 33, or it may be applied to both the inner surface of the mounting base 11 and the outer surface of the heating barrel 21. Alternatively, in another embodiment, there is no gap between the barrel wall of the heating barrel 21 and the inner surface of the mounting base 11, and the reflective insulating layer 34 is interposed between the heating barrel 21 and the mounting base 11.

[0041] In some embodiments, the thickness of the reflective heat insulating layer 34 is 0.2 mm or less, which can save materials and reduce costs. In specific implementations, the thickness of the reflective heat insulating layer 34 can be 0.08 mm, 0.1 mm, 0.12 mm, 0.15 mm, 0.18 mm, 0.2 mm, etc.

[0042] In some embodiments, the reflective thermal insulation layer 34 is a reflective thermal insulation film made of a low-emissivity material, which improves the thermal radiation reflection performance of the reflective thermal insulation layer 34. Here, the reflective thermal insulation layer 34 includes any of an aluminum layer, a silver layer, a stainless steel layer, and a ceramic layer.

[0043] 2 to 4, 16, and 19, in one embodiment, for the entire non-combustion heating device, the device body 100 includes a housing 101 having an aerosol outlet 102. The atomizing and heating assembly 200 is sandwiched within the housing 101 in the axial direction of the heating barrel 21, the aerosol outlet 102 can communicate with the accommodating cavity via a communicating channel 121, and the aerosol product 40 can be inserted from the aerosol outlet 102 into the accommodating cavity via the communicating channel 121 to attach the aerosol product 40 to the atomizing and heating assembly 200.

[0044] The housing 101 may be provided with a positioning ring 103 at the aerosol outlet 102, and the sealing member 12 is sandwiched between the insulating barrel 14 and the positioning ring 103 in the axial direction of the heating barrel 21, thereby fixing the positions of the sealing member 12 and the positioning ring 103 within the housing 101. The positioning ring 103 and the sealing member 12 surround each other to form a ring groove. A circular clamping member 13 is mounted within the ring groove. The clamping member 13 is made of a rubber material and has protrusions 131 extending radially inward. The protrusions 131 are uniformly spaced around the periphery of the clamping member 13, allowing the aerosol product 40 to enter the housing 101 from the aerosol outlet 102, pass through the communication channel 121 of the sealing member 12, and enter the receiving cavity formed by the surrounding heating barrel 21. After the aerosol product 40 enters the receiving cavity, the clamping member 13 can elastically contact the outer circumferential surface of the aerosol product 40 in the radial direction of the heating barrel 21 via the protrusions 131, thereby positioning and fixing the aerosol product 40 and preventing it from shaking. It also prevents the aerosol product 40 from moving axially and detaching from the receiving cavity due to the frictional force of contact, improving the assembly stability of the aerosol product 40 and preventing the normal heating operation of the aerosol product 40 from being affected.

[0045] 3 to 10, 14 to 16, and 19, in some embodiments, the side wall 211 of the heating barrel 21 has a contact protrusion 2112 protruding into the receiving cavity, and the side wall 211 of the heating barrel 21 further has a recess 2113. After the aerosol product 40 is installed in the receiving cavity, the contact protrusion 2112 comes into thermally conductive contact with the outer surface of the aerosol product 40, transferring heat from the heating barrel 21 to the aerosol product 40 and realizing heating of the aerosol product 40 through direct contact. After the contact protrusion 2112 comes into contact with the outer surface of the aerosol product 40, the recess 2113 in the side wall 211 of the heating barrel 21 surrounds the outer surface of the aerosol product 40 to form an intake passage 31 communicating with the aerosol outlet 102, and the external cold air that enters the housing 101 from the aerosol outlet 102 can enter the intake passage 31 through the gap between two adjacent protrusions 131 in the clamping member 13 and the annular gap between the sealing member 12 and the aerosol product 40.

[0046] 5 , in one embodiment, the contact protrusions 2112 on the side wall 211 of the heating barrel 21 include contact ribs extending in the axial direction of the heating barrel 21. The length of the contact rib may be equal to or slightly shorter than the dimension of the side wall 211 of the heating barrel 21 in the axial direction of the heating barrel 21. There may be multiple contact ribs, and any two adjacent contact ribs are arranged at equal intervals in the circumferential direction of the heating barrel 21, and a recess 2113 is formed in the side wall 211 of the heating barrel 21 between any two adjacent contact ribs. The recess 2113 is formed as a groove extending in the axial direction of the heating barrel 21. The multiple recesses 2113 are arranged at equal intervals in the circumferential direction of the heating barrel 21, and the intake passage 31 formed by being surrounded by the recesses 2113 and the outer circumferential surface of the aerosol product 40 is also arranged at equal intervals in the circumferential direction of the heating barrel 21. In this way, a plurality of intake passages 31 extending in the axial direction of the heating barrel 21 and arranged at equal intervals in the circumferential direction are formed between the aerosol product 40 and the side wall 211 of the heating barrel 21. This contributes to reducing the flow resistance of the airflow in the intake passages 31, thereby reducing the suction resistance of the non-combustion heating device and also contributes to realizing a uniform distribution of the intake airflow in the circumferential direction of the aerosol product 40.

[0047] In another embodiment, the contact protrusions 2112 on the side wall 211 of the heating barrel 21 may further include circular dot-like protrusions. There are a plurality of circular dot-like protrusions, and two adjacent circular dot-like protrusions are arranged at equal intervals in the circumferential and axial directions of the heating barrel 21. A recess 2113 is formed on the side wall 211 of the heating barrel 21 between the two adjacent circular dot-like protrusions. The recess 2113 and the outer peripheral surface of the aerosol product 40 surround the intake passage 31, thereby forming the intake passage 31. In this way, the intake passage 31 can also extend in the axial direction of the heating barrel 21, thereby reducing the flow resistance of the airflow in the intake passage 31 and reducing the suction resistance.

[0048] In some other embodiments, the contact protrusions 2112 on the side wall 211 of the heating barrel 21 may include a wavy band structure or other irregular structure, as long as the contact protrusions 2112 can contact the outer surface of the aerosol product 40 and the recesses 2113 formed between two adjacent contact protrusions 2112 surround the outer surface of the aerosol product 40 to form an intake passage 31 communicating with the aerosol outlet 102.

[0049] The side wall 211 of the heating barrel 21 has a contact protrusion 2112 and a recess 2113, and the contact protrusion 2112 can be in thermal conduction contact with the outer circumferential surface of the aerosol product 40, and the recess 2113 can form the structure of an enclosed intake passage 31 together with the outer circumferential surface of the aerosol product 40. Meanwhile, the direct contact between the contact protrusion 2112 and the outer circumferential surface of the aerosol product 40 transfers heat from the heating barrel 21 to the aerosol product 40, thereby realizing heating of the aerosol product 40. On the other hand, when external cold air flows through the intake passage 31, the contact between the side wall 211 of the heating barrel 21 and the air flow in the intake passage 31 causes the heat of the side wall 211 of the heating barrel 21 to be transferred to the air flow in the intake passage 31, forming a hot air flow, which makes it easier to heat the aerosol product 40 by the subsequent hot air flow and improves the uniformity of heating of the aerosol product 40. In this way, heating of the aerosol product 40 is achieved using the method of direct contact and heating by hot air flow, which effectively improves the thermal utilization rate of the atomization heating assembly 200, further reducing the heat loss of the non-combustion heating device and reducing the energy consumption of the non-combustion heating device.

[0050] In some embodiments, the contact protrusion 2112 may be embedded within the aerosol product 40 to increase the contact area between the aerosol product 40 and the side wall 211 of the heating barrel 21, thereby improving the heat transfer efficiency between the heating barrel 21 and the aerosol product 40.

[0051] 5, in one embodiment, the thickness of the contact rib extends in the circumferential direction of the heating barrel 21, and the thickness dimension of the contact rib may be set to gradually decrease in the radial direction of the heating barrel 21 from the side wall 211 of the heating barrel 21 toward the containing cavity. This makes it easier to fit the contact rib into the aerosol product 40, and the contact area between the contact rib and the aerosol product 40 increases, improving the heat transfer efficiency between the heating barrel 21 and the aerosol product 40. Meanwhile, fitting the contact rib into the aerosol product 40 can also reduce the probability of the aerosol product 40 detaching from the containing cavity.

[0052] Furthermore, in one embodiment, the thickness dimension of the contact rib may be set to gradually increase in the axial direction of the heating barrel 21 from the open end 214 to the closed end 215 of the heating barrel 21. This allows the contact rib to be firmly pressed into the aerosol product 40 in the axial direction of the heating barrel 21, thereby further increasing the contact area between the aerosol product 40 and the heating barrel 21, improving heat transfer efficiency, and further reducing the probability of the aerosol product 40 detaching from the containing cavity.

[0053] In another embodiment, the contact protrusions 2112 may be configured to include point-like protrusions having a shape similar to a cone. The point-like protrusions have tips located radially inward in the radial direction of the heating barrel 21 and can be fitted into the aerosol product 40 via the tips of the point-like protrusions, thereby increasing the contact area between the contact protrusions 2112 and the aerosol product 40.

[0054] To ensure that the hot airflow generated in the intake passage 31 can heat the aerosol product 40, the bottom wall 212 or the side wall 211, or both the bottom wall 212 and the side wall 211 of the heating barrel 21 must be provided with a support protrusion 2121 facing the receiving cavity. The support protrusion 2121 is configured to support the aerosol product 40 along the axial direction of the heating barrel 21, thereby preventing contact between the aerosol product 40 and the bottom wall 212 of the heating barrel 21. This forms an intake cavity 32 between the aerosol product 40 and the bottom wall 212 of the heating barrel 21, which communicates with the intake passage 31. The hot airflow generated in the intake passage 31 can enter the intake cavity 32 and then enter the aerosol product 40 from the axial end of the aerosol product 40 to heat it. The aerosol generated by heating can pass through the aerosol outlet 102 and be discharged from the other end of the aerosol product 40. The direction indicated by the arrows in Figures 16 and 19 is the direction of airflow. The arrangement of the intake cavity 32 provides sufficient space for the hot airflow, particularly at the position opposite the axial end of the aerosol product 40, to effectively prevent the hot airflow from being blocked and ensure that the hot airflow is sucked into the inside of the aerosol product 40 from the axial end of the aerosol product 40.

[0055] 3 to 10, 14 to 16, and 19, in some embodiments, the support protrusions 2121 may be arranged to be located on the bottom wall 212 of the heating barrel 21. There are a plurality of support protrusions 2121, and two adjacent support protrusions 2121 are arranged at an interval on the bottom wall 212 of the heating barrel 21, and a communication gap 2122 is formed between the two adjacent support protrusions 2121, and communication between the intake passage 31 and the intake cavity 32 can be achieved through the communication gap 2122.

[0056] 5 , in one embodiment, the support protrusion 2121 is configured to include a support rib. The support rib is arranged to extend in the radial direction of the heating barrel 21, and the dimension of the support rib in the radial direction of the heating barrel 21 is smaller than the radial dimension of the containing cavity. Thus, an intake cavity 32 is formed between the bottom wall 212, on which the support rib is not provided, and the aerosol product 40, and a communication gap 2122 is formed between two adjacent support ribs, and the communication gap 2122 connects the intake passage 31 and the intake cavity 32.

[0057] Furthermore, in one embodiment, referring to FIG. 5 , the number of support ribs may be equal to the number of contact ribs, and the support ribs may be connected to the contact ribs in a one-to-one correspondence. In this way, the communication gap 2122 and the intake passage 31 are directly connected to each other in the axial direction of the heating barrel 21. On the one hand, the resistance force of the hot airflow from the intake passage 31 to the intake cavity 32 is reduced, thereby reducing suction resistance. On the other hand, the movement direction of each airflow is clear and does not flow to adjacent points, thereby effectively avoiding vibration caused by turbulent airflow. This improves the stability of the aerosol product 40 during inhalation and is beneficial to improving the user experience.

[0058] In another embodiment, the support protrusions 2121 may be configured to include cylindrical dot-like protrusions. The cylindrical dot-like protrusions are located on the bottom wall 212 of the heating barrel 21 so as to support the axial end surface of the aerosol product 40. A communication gap 2122 is formed between two adjacent cylindrical dot-like protrusions, and an intake cavity 32 is further formed between the bottom wall 212 and the aerosol product 40 where no cylindrical dot-like protrusions are provided. In this way, communication between the intake passage 31 and the intake cavity 32 can be achieved through the communication gap 2122.

[0059] Of course, in other embodiments, some of the support protrusions 2121 may be arranged to be located on the side wall 211 of the heating barrel 21. For example, the support protrusions 2121 include support ribs, which are spaced apart from the bottom wall 212 of the heating barrel 21, and which are connected to contact ribs, forming a communication gap 2122 between two adjacent support ribs. The support ribs support the aerosol product 40, thereby forming an intake cavity 32 between the bottom wall 212 of the heating barrel 21 and the aerosol product 40, and the communication gap 2122 connects the intake passage 31 and the intake cavity 32.

[0060] In an embodiment in which the communication gap 2122 between the two support protrusions 2121 realizes communication between the intake passage 31 and the intake cavity 32, the hot air flow in the intake passage 31 can enter the intake cavity 32 through the communication gap 2122 and then enter the aerosol product 40 from the end of the aerosol product 40, thereby realizing heating of the aerosol product 40. A part of the hot air flow can be stored through the intake cavity 32, ensuring the continuity of aerosol generation by the aerosol product 40.

[0061] 3 to 5, in one embodiment, the heating barrel 21 is configured as a conductive ceramic structure, that is, the heating barrel 21 is made of a conductive ceramic material, and the heating barrel 21 itself can generate heat after being energized, which facilitates the processing and manufacturing of the atomization and heating assembly 200 and contributes to ensuring the structural consistency between the atomization and heating assembly 200 and the entire non-combustion heating device.

[0062] In some embodiments, the atomization heating assembly 200 includes an external lead 22. A positive electrode connection part (not shown) and a negative electrode connection part (not shown) that are connected to the external lead 22 are disposed on the outer circumferential surface of the heating barrel 21, and the heating barrel 21 is electrically connected to the power supply device 104 in the device main body 100 via the external lead 22, making it possible to control the heating of the atomization heating assembly 200 via the circuit board.

[0063] In one embodiment, multiple external conductors 22 are arranged, and multiple positive and negative electrode connection parts are arranged at intervals on the corresponding heating barrels 21, and the current flow to different external conductors 22 is controlled respectively, thereby realizing heating of each zone of the heating barrels 21 or heating film.

[0064] Furthermore, the number of positive electrode connectors may be two, three, four, or more. The multiple positive electrode connectors are arranged at intervals in the axial direction of the heating barrel 21, and the positive electrode connectors and negative electrode connectors are arranged alternately in the axial direction of the heating barrel 21. The number of external conductors 22 is equal to the sum of the number of positive electrode connectors and the number of negative electrode connectors, and an external conductor 22 is connected to each positive electrode connector and each negative electrode connector. By controlling the current flow between two adjacent positive electrode connectors and negative electrode connectors located at different axial positions, the region between the current-flowing positive electrode connector and negative electrode connector in the heating barrel 21 can be heated. Sequentially controlling the heating of different heating regions in the axial direction of the heating barrel 21 ensures continuity of aerosol generation and contributes to ensuring a pleasant mouthfeel during use at each stage of aerosol generation.

[0065] Of course, in other embodiments, there may be one positive connection and one negative connection, as long as the heating barrel 21 can heat the aerosol product 40 and the airflow.

[0066] In some embodiments, the atomization and heating assembly 200 further includes a heating structure 50. The heating structure 50 is located outside the heating barrel 21 and fixed to the side wall 211 of the heating barrel 21. The heating structure 50 heats the heating barrel 21, radiates infrared rays into the accommodating cavity, and heats the air flowing through the intake passage 31 to generate a hot air current, thereby simultaneously heating the aerosol product 40 inserted into the accommodating cavity with infrared rays and hot air current. This effectively increases the amount of heat received inside the aerosol product 40, making the heat received inside and outside the aerosol product 40 more uniform, which is beneficial to improving atomization efficiency.

[0067] When the aerosol product 40 is inserted into the receiving cavity and heated, the heating structure 50 transfers heat directly to the aerosol product 40 by emitting infrared rays, and also transfers heat to the heating barrel 21, which heats the airflow flowing through the intake passage 31 to form a hot airflow. As the user inhales the aerosol product 40, the hot airflow flows along the intake passage 31 to the intake cavity 32 and is sucked into the aerosol product 40, where the heat of the hot airflow further heats the interior of the aerosol product 40. Alternatively, the aerosol product 40 in contact with the heating barrel 21 can be heated by the heating barrel 21, thereby achieving heating of the aerosol product 40 by a direct heating method.

[0068] Referring to FIG. 6 , the heating structure 50 includes a heating element 51 and an electrical connection member 52. The heating element 51 is connected to the sidewall 211 of the heating barrel 21 and extends circumferentially around the heating barrel 21. The electrical connection member 52 is also disposed on the sidewall 211 of the heating barrel 21 and connected to the heating element 51. The electrical connection member 52 can be connected to the power supply device 104 via an external lead 22. The power supply device 104 supplies power to the heating element 51, causing the heating element 51 to generate heat and further heating the corresponding region of the heating barrel 21. The heating barrel 21 is made of a material that is transparent to infrared rays. When the heating element 51 generates heat, the generated infrared rays pass through the heating barrel 21 and radiate into the accommodating cavity, heating the aerosol product 40 in the accommodating cavity and the airflow in the intake passage 31. The number of heating elements 51 may be one or more, and the number of electrical connection members 52 is determined according to the number of heating elements 51.

[0069] The heating barrel 21 can be made of, but is not limited to, glass or ceramic. The heating barrel 21 made of the above materials is suitable for infrared transmission and has high thermal conductivity, allowing it to heat the aerosol product 40 by contacting it, or allowing infrared rays to pass through the heating barrel 21 and directly heat the aerosol product 40.

[0070] 6 , in some embodiments, the heating element 51 specifically includes a first heating element 511 and a second heating element 512, and the electrical connection element 52 specifically includes a first bonding pad 521, a second bonding pad 522, and a third bonding pad 523. The first heating element 511 and the second heating element 512 are spaced apart along the extension direction of the heating element 21 on the side wall 211 of the heating element 21, and in the extension direction of the heating element 21, the first heating element 511 is close to the open end 214 of the heating element 21, and the second heating element 512 is far from the open end 214 of the heating element 21. The first bonding pad 521, the second bonding pad 522, and the third bonding pad 523 are all provided between the first heating element 511 and the second heating element 512. The first heating element 511 has one circumferential end connected to the first bonding pad 521 and the other end connected to the second bonding pad 522. The second heating element 512 has one circumferential end connected to the first bonding pad 521 and the other end connected to the third bonding pad 523. The first bonding pad 521, the second bonding pad 522, and the third bonding pad 523 are each electrically connected to the power supply device 104 or a corresponding circuit, thereby allowing the first heating element 511 and the second heating element 512 to be connected in parallel. Here, the bonding pads and the heating element 51 may be connected by a conductor such as conductive silver paste or a conductive wire.

[0071] 6 , when the first bonding pad 521 and the second bonding pad 522 are turned on simultaneously, the first heating element 511 is energized, and the first heating element 511 generates heat independently. When the first bonding pad 521 and the third bonding pad 523 are turned on simultaneously, the second heating element 512 is energized, and the second heating element 512 generates heat independently. When the first bonding pad 521, the second bonding pad 522, and the third bonding pad 523 are turned on simultaneously, the first heating element 511 and the second heating element 512 are energized simultaneously and generate heat. The power supply device 104 or a corresponding circuit can individually control the heating temperatures of the first heating element 511 and the second heating element 512 to perform corresponding adjustments and controls according to usage needs.

[0072] For example, the end of the aerosol product 40 that is located within the receiving cavity in its extension direction, i.e., in the extension direction of the heating barrel 21, is the inhalation end, and the substrate segment of the aerosol product 40 that contains the aerosol substrate is located at the inhalation end, while the portion of the aerosol product 40 that is located outside the receiving cavity and is wrapped around the user's lips is the filter segment. In the initial stage of heating the aerosol product 40, the first heating element 511 can be controlled to be primarily heated. That is, the heating temperature of the first heating element 511 is higher than the heating temperature of the second heating element 512, thereby first heating the substrate segment in the aerosol product 40 at a position adjacent to the filter segment. After heating for a predetermined period of time, the second heating element 512 can be controlled to be primarily heated. That is, the heating temperature of the first heating element 511 is lowered while the heating temperature of the second heating element 512 is simultaneously raised. At this time, the substrate segment of aerosol product 40 is heated mainly at a position away from the filter segment, thereby preventing the temperature of the portion of aerosol product 40 close to the filter segment from becoming too high and causing mouth burns. The predetermined time and specific heating temperature can be set according to actual usage needs, and will not be described here.

[0073] 7 to 9 , in some embodiments, the heating structure 50 of the atomization heating assembly 200 includes a heat-shrinkable tube 53 and a heating circuit body 54. Heat generated in the heating circuit body 54 is transferred into the accommodating cavity via the heating barrel 21. The heating circuit body 54 has a sleeve-shaped socket portion 541, and the socket portion 541 and the heat-shrinkable tube 53 are both fitted onto the outer periphery of the heating barrel 21, and the socket portion 541 is interposed between the heating barrel 21 and the heat-shrinkable tube 53. The heat-shrinkable tube 53 is used to apply a fixing force to the heating circuit body 54 from the outside of the socket portion 541 to prevent the heating circuit body 54 from detaching from the heating barrel 21.

[0074] The heating barrel 21 has thermal conductivity, and the heat generated when the heating circuit 54 is energized is transferred through the heating barrel 21 into the receiving cavity to heat the aerosol product 40 located in the receiving cavity. The heating barrel 21 may be made of a highly thermally conductive material such as an aluminum alloy, copper, or aluminum oxide. By using a highly thermally conductive material to manufacture the heating barrel 21, the thermal conductivity of the heating barrel 21 is improved, and the heat generated by the heating circuit 54 is transferred as much as possible into the receiving cavity, reducing the loss of thermal energy.

[0075] By fitting the socket portion 541 of the heating circuit 54 onto the outer periphery of the heating barrel 21, the heating circuit 54 is not connected to the heating barrel 21 using a thick film construction method, but is pre-fabricated and then fitted onto the outer periphery of the heating barrel 21. Because the heating circuit 54 is pre-fabricated without a thick film construction method, the inconsistent thickness or width of different segments that can occur when using a thick film construction method is avoided, thereby ensuring the consistency of the entire heating circuit 54. Furthermore, by fitting the heat shrink tube 53 onto the outer periphery of the heating barrel 21, the socket portion 541 is interposed between the heating barrel 21 and the heat shrink tube 53, and the heat shrink tube 53 applies a fixing force to the heating circuit 54 from the outside of the socket portion 541, thereby securing the heating circuit 54 and preventing it from detaching from the heating barrel 21. Therefore, the heating structure 50 of this embodiment improves the consistency of the heating circuit 54 and ensures the stable installation of the heating circuit 54.

[0076] 8 and 9, the heating circuit 54 further includes an electrical connection pin 542. One end of the electrical connection pin 542 is electrically connected to the socket 541, and the other end is electrically connected to the power supply device 104 via the external conductor 22, thereby enabling the power supply device 104 to supply power to the heating circuit 54.

[0077] In some embodiments, the heat shrink tube 53 is a heat shrink sleeve tube made of a polyolefin material, which shrinks and deforms when heated, and is used to apply a fixing force to the socket portion 541. The heat shrinkability of the heat shrink tube 53 can be utilized to provide a good fixing effect to the heating circuit body 54. In addition, the heat shrink tube 53 is soft and has flame retardant, insulating, and corrosion-resistant properties, and can provide good protection for the heating circuit body 54.

[0078] In some embodiments, a mounting groove is provided in the side wall 211 of the heating barrel 21, and the socket portion 541 is mounted in the mounting groove. Mounting the socket portion 541 in the mounting groove can improve the stability of the connection of the heating circuit body 54 to the heating barrel 21. Of course, in other embodiments, the side wall 211 of the heating barrel 21 does not have to be provided with a mounting groove.

[0079] In some embodiments, the heating circuit 54 includes a set of sub-heating circuits that can cover a substrate segment of the aerosol product 40. In other embodiments, the heating circuit 54 may include at least two sets of sub-heating circuits, and it should be understood that in specific implementations, the at least two sets of sub-heating circuits may be arranged along the axial direction of the heating barrel 21 or may be arranged to surround the circumferential side of the heating barrel 21.

[0080] In some embodiments, the heating circuit 54 is manufactured by laser cutting. Laser cutting is a highly accurate process that effectively ensures consistency throughout the circuit. It should be understood that in other embodiments, the heating circuit 54 may be manufactured by methods such as stamping or machining.

[0081] In some embodiments, referring to FIGS. 10 to 15 , the atomizing and heating assembly 200 includes a heating structure 50 and a substrate layer 60. The substrate layer 60 is fixed to the sidewall 211 between the outer flange 213 and the bottom wall of the heating barrel 21, and the heating structure 50 is fixed to the substrate layer 60. The heating structure 50 may be in the form of a sheet, a mesh, or a thread. For example, in the case of a sheet-shaped heating structure 50, the heating structure 50 may be directly fixed to the outer surface of the heating barrel 21 by screen printing. Specifically, the heating barrel 21 is placed on a rotatable jig, and a sheet-shaped screen plate is tightly attached to the sidewall 211 of the heating barrel 21. The jig is rotated while scraping off the raw material of the heating structure 50 from the screen plate with a shovel, thereby fixing the heating structure 50. However, due to the structural design of the outer flange 213, the screen plate cannot be attached to the heating barrel 21, and therefore the heating structure 50 cannot be fixed to the outer wall of the heating barrel 21. In view of this problem, in this embodiment, the heating structure 50 can be fixed to the substrate layer 60, and the substrate layer 60 can be fixed to the outer wall of the heating barrel 21. For example, the heating structure 50 can be fixed to the substrate layer 60 by thick film printing, and then the substrate layer 60 with the heating structure 50 fixed thereto can be fixed to the outer wall of the heating barrel 21 by sintering, so that the heating structure 50 is indirectly fixed to the heating barrel 21, thereby reducing the difficulty of fixing the heating structure 50 to the heating barrel 20.

[0082] The substrate layer 60 may be made of a material that can be used in tape casting, such as metal or ceramic, and has a certain degree of thermal conductivity. The substrate layer 60 is a sheet layer manufactured by tape casting, and the substrate layer 60 manufactured in this manner has a certain degree of flexibility. For example, as shown in Figures 11 to 13, the substrate layer 60 in the unfolded state is a rectangular sheet layer, and the rectangular sheet layer is easily bonded and fixed to the outer wall of the heating barrel 21 by its own flexible deformation to form a columnar substrate layer 60, such as the substrate layer 60 shown in Figure 10.

[0083] The thinner the thickness of the substrate layer 60, the faster the heat conduction speed of the substrate layer 60 and the more uniform the heat conduction becomes. Specifically, the thickness of the substrate layer 60 is 25 μm to 500 μm.

[0084] The aerosol product 40 can be divided into many types according to different usage needs, and can be roughly divided into two types based on the difficulty of generating aerosol: an aerosol product that can generate aerosol quickly with just a little heat, and an aerosol product that is difficult to generate aerosol, which requires a lot of heat to generate aerosol. The atomizing and heating assembly 200 designed in this application is applied to aerosol products that are difficult to generate aerosol.

[0085] Because aerosol products 40 that are difficult to generate aerosols require a large heating area, conventional atomization and heating assemblies 200 heat the entire aerosol product 40 that they come into contact with. However, because one heating structure 50 is used, only one heating method can be provided for the aerosol product 40, and it is not possible to provide heat according to the demands of the aerosol product 40 at different times, making it difficult to flexibly control. Furthermore, when a large amount of heat is provided to the aerosol product 40 using a global heating method, it is easy for the problem of mouth burns to occur, especially in the initial heating stage of the aerosol product 40.

[0086] In one embodiment, the heating structure 50 includes a first heating element 61 and a second heating element 62 connected in parallel. The first heating element 61 and the second heating element 62, connected in parallel, are fixed to the heating barrel 21 via a substrate layer 60. Because the first heating element 61 and the second heating element 62 are two relatively independent heating elements, the heating structure 50 can be easily flexibly controlled, the problem of mouth burns occurring when the atomizing heating assembly 200 heats the aerosol product 40 can be solved, and more heating modes can be provided for the aerosol product 40. Specifically, when the atomizing heating assembly 200 is used to heat the aerosol product 40 in the heating barrel 21, the first heating element 61 and the second heating element 62 can operate synchronously or asynchronously. For example, the second heating element 62 may not operate when the first heating element 61 operates, or the first heating element 61 may not operate when the second heating element 62 operates, or the first heating element 61 and the second heating element 62 may operate simultaneously. The specific combined operation manner of the first heating element 61 and the second heating element 62 is not limited, and may be flexibly combined according to the actual heat demand of the aerosol product 40 to be heated, as long as it avoids the problem of burning the mouth due to the heat provided by the entire heating structure 50 to the aerosol product 40.

[0087] 14 and 15, the first heating element 61 and the second heating element 62 are indirectly fixed to the heating element 21 along the axial direction of the heating element 21, respectively, to heat different axial segments of the aerosol product 40. For example, if the first heating element 61 is adjacent to the open end 214 of the heating element 21 and the second heating element 62 is adjacent to the bottom wall 212 of the heating element 21, when starting to heat the aerosol product 40, the first heating element 61 can be activated preferentially or mainly, thereby preferentially heating a portion of the substrate segment adjacent to the top of the aerosol product 40, further facilitating rapid aerosol release, and appropriately reducing the heat provided to the aerosol product 40 by the atomizing and heating assembly 200, thereby avoiding the risk of mouth burns. After heating the aerosol product 40 for a certain period of time, the second heater 62 can be operated alone, or the second heater 62 can be used primarily to heat the aerosol product 40, thereby allowing the aerosol product 40 to continuously emit aerosol. When the first heater 61 is used primarily, the second heater 62 is used as an auxiliary heater, and in this case, the heat generated by the second heater 62 must be lower than the heat generated by the first heater 61. Similarly, when the second heater 62 is used primarily, the first heater 61 is used as an auxiliary heater, and the heat generated by the first heater 61 must be lower than the heat generated by the second heater 62.

[0088] Here, the first heating element 61 forms at least one layer of first heating rings 611 along the circumferential direction of the heating barrel 21, and the first heating element 61 realizes a series connection of the first heating rings 611 of adjacent layers by bending. The second heating element 62 forms at least one layer of second heating rings 621 along the circumferential direction of the heating barrel 21, and the second heating element 62 realizes a series connection of the second heating rings 621 of adjacent layers by bending.

[0089] When the first heating element 61 forms a first heating ring 611 along the circumferential direction of the heating barrel 21 and the second heating element 62 forms a second heating ring 621 along the circumferential direction of the heating barrel 21, the heating structure 50 can provide a more uniform heating effect on the outer circumferential surface of the aerosol product 40 at the same axial position. More specifically, the longitudinal direction of the first heating ring 611 in the same layer is perpendicular to the axial direction of the heating barrel 21, and the longitudinal direction of the second heating ring 621 in the same layer is also perpendicular to the axial direction of the heating barrel 21. This ensures that the heating structure 50 can provide a more uniform heating effect on the outer circumferential surface of the aerosol product 40 at the same axial position. Take FIG. 11 as an example, which mainly shows the specific structure of the heating structure 50 when the substrate layer 60 is deployed. In this case, the longitudinal directions of the first heating ring 611 and the second heating ring 621 are both horizontal, and the axial direction of the heating barrel 21 is vertical.

[0090] Of course, in other embodiments, for example, the first heating element 61 may be fixed to the circumferential surface of the heating barrel 21 in a spiral shape. In this case, the first heating element 61 is arranged correspondingly to some points on the circumferential surface of the aerosol product 40 at the same axial position, and the first heating element 61 is not arranged at other points. That is, the heating structure 50 cannot provide a uniform heating effect on the circumferential surface of the aerosol product 40 at the same axial position.

[0091] 11 , specifically, in some embodiments, the first heating element 61 forms two layers of first heating rings 611, and the second heating element 62 forms two layers of second heating rings 621. The first heating ring 611 closest to the second heating element 62 and the second heating ring 621 closest to the first heating element 61 both have semi-annular structures, and the two semi-annular structures form one layer of heating rings. That is, in this case, the first heating ring 611 and the second heating ring 621 form a total of three layers of heating rings. That is, in this case, the first heating element 61 and the second heating element 62 each form 1.5 heating rings around the circumferential surface of the heating barrel 21, and the first heating element 61 and the second heating element 62 are arranged symmetrically on the circumferential surface of the heating barrel 21. For example, in FIG. 11 , the first heating element 61 is arranged diagonally at the upper tier near the upper right corner of the circumferential surface of the heating barrel 21, and the second heating element 62 is arranged diagonally at the lower tier near the lower left corner of the circumferential surface of the heating barrel 21. 11, when the first heating ring 611 and the second heating ring 621 each form a 1.5-circumference heating ring, the peripheral surface of the substrate layer 60 is developed into a rectangular shape (the developed shape of the outer peripheral surface of the heating cylinder 21 is also rectangular or approximately rectangular), and the length of the heating rings in the same layer is approximately the same as the length of the peripheral surface of the heating cylinder 21, so that the heating rings in the same layer form an approximately one-circumference ring structure on the cylindrical surface of the undeveloped heating cylinder 21. When the heating rings in the same layer are formed by combining some of the first heating rings 611 and some of the second heating rings 621, the length of the heating rings in the same layer refers to the sum of the lengths of the first heating rings 611 and the second heating rings 621 in that layer.

[0092] In other embodiments, when the first heating element 61 and the second heating element 62 form three heating ring layers on the heating barrel 21, other ratios may be used. For example, the first heating element 61 may form 1.4 heating ring layers on the heating barrel 21, and the second heating element 62 may form 1.6 heating ring layers on the heating barrel 21. Alternatively, in other embodiments, as shown in FIG. 12, the first heating element 61 forms two first heating ring layers 611 on the heating barrel 21, and the second heating element 62 forms two second heating ring layers 621 on the heating barrel 21. Alternatively, in other embodiments, as shown in FIG. 13, the first heating element 61 forms one first heating ring layer 611 on the heating barrel 21, and the second heating element 62 forms two second heating ring layers 621 on the heating barrel 21. The number of turns or rings formed by the first heating ring 611 and the second heating ring 621 is not comprehensively listed here, and may be flexibly selected according to actual heating needs. When the first heating element 61 and the second heating element 62 form a circumferential heating ring, a uniform energy distribution can be provided on different peripheral surfaces of the aerosol product 40 at the same axial position, which helps to provide a uniform heating effect on the aerosol product 40 at the same axial position.

[0093] 11 to 13, in some embodiments, a connection electrode 63 is provided at each of the distant ends of the first heating element 61 and the second heating element 62, and a common electrode 64 is provided between the close ends of the first heating element 61 and the second heating element 62. The connection electrode 63 is used to electrically connect to one of the positive and negative electrodes of the power supply device 104, and the common electrode 64 is used to electrically connect to the other of the positive and negative electrodes of the power supply device 104. By introducing the common electrode 64 between the first heating element 61 and the second heating element 62 that are connected in parallel, the circuit connections of the atomization heating assembly 200 can be simplified.

[0094] More preferably, the resistance value of the first heating element 61 is equal to or close to the resistance value of the second heating element 62. When the resistance value of the first heating element 61 is equal to or close to the resistance value of the second heating element 62, it is advantageous for heating the aerosol product 40 to provide a uniform energy distribution, and it is also advantageous for flexibly controlling the heating structure 50.

[0095] 10 to 15, the thermal conductivity of the heating barrel 21 is 10 W / m·K or more, which allows the heating barrel 21 to uniformly transfer heat from the heating structure 50. The material of the heating barrel 21 may be, for example, an aluminum alloy, copper, aluminum nitride, or the like.

[0096] 16 , in some embodiments, the atomization heating assembly 200 employs electromagnetic induction heating to heat the aerosol product 40. The atomization heating assembly 200 includes a mounting base 11. The heating barrel 21 is attached to the mounting base 11, and a closed end 215 of the heating barrel 21 in its extension direction is suspended from and spaced apart from the mounting base 11. The atomization heating assembly 200 further includes a coil 71. The coil 71 is located on the opposite side of the closed end 215 from the accommodating cavity in the extension direction of the heating barrel 21, and has an inner ring (here, the innermost winding portion) and an outer ring (here, the outermost winding portion). The winding size (here, the winding radius) of the inner ring is smaller than that of the outer ring, and the coil 71 is used to generate an alternating magnetic field, and the heating barrel 21 is inductively coupled to the coil 71 to generate heat using the alternating magnetic field. By adopting this electromagnetic heating method, there is no need to separately arrange an external conducting wire 22 in the heating barrel 21, and it is possible to avoid an increase in energy consumption due to current flowing through the external conducting wire 22, thereby contributing to a reduction in energy consumption of the atomization heating assembly 200.

[0097] In one embodiment, the coil 71 may be installed so as to be attached to the end surface of the closed end 215 of the heating barrel 21 by a locking structure. The outside of the coil 71 has an insulating layer, or the portion of the heating barrel 21 that comes into contact with the coil 71 is made of an insulating material, which contributes to reducing the distance between the heating barrel 21 and the coil 71 and helps to improve the efficiency of converting magnetic field energy into electrical energy under conditions that reach an equivalent heating temperature, thereby reducing the energy consumption of the entire atomization heating assembly 200.

[0098] 16 , the coil 71 may be further spaced apart from the heating barrel 21 in the extension direction of the heating barrel 21. For example, the mounting base 11 may be configured to have a support surface perpendicular to the extension direction of the heating barrel 21, and the support surface may be the end surface facing the sealing member 12 of the plug 15 or the bottom wall surface of the heat insulating barrel 14, and the coil 71 may be attached so as to be supported on the support surface of the mounting base 11. This allows the coil 71 to be attached and fixed to the mounting base 11. Alternatively, in other embodiments, the coil 71 may be attached to the end surface of the closed end 215 of the heating barrel 21 by an adhesive layer having a certain thickness, and by arranging the coil 71 at a distance from the end surface of the closed end 215, insulation between the heating barrel 21, which has conductive properties, and the coil 71 is satisfied, and the need to arrange a separate insulating layer on the coil 71 or the heating barrel 21 to insulate the coil 71 from the heating barrel 21 is avoided. In this way, the distance between the heating barrel 21 and the coil 71 is shortened, and the efficiency of converting magnetic field energy into electrical energy is improved.

[0099] 17 and 18, in one embodiment, coil 71 is arranged to be wound in a plane perpendicular to the extension direction of heating barrel 21, and coil 71 has a planar coil structure. Coil 71 may have a circular coil structure, or in other embodiments, may have a polygonal or elliptical structure. Coil 71 has an inner ring (here, the innermost winding portion) and an outer ring (here, the outermost winding portion), and in a circular coil structure, the winding radius of the inner ring is smaller than the winding radius of the outer ring, and in other coil structures, the winding size of the inner ring is smaller than the winding size of the outer ring.

[0100] In other embodiments, to accommodate the structure of the support surface on the mounting base 11, the coil 71 may have a conical structure, and the inner and outer rings of the coil 71 may be spaced apart in the extension direction of the heating barrel 21.

[0101] In one embodiment, the wound wire in the coil 71 may be a wire having a circular cross section. Of course, in other embodiments, the wound wire may be a flat strip of wire that is wound through its thickness to form the overall structure of the coil 71.

[0102] 16 , in some embodiments, the heating barrel 21 and the inner barrel wall of the insulating barrel 14 are spaced apart. In this manner, the insulating barrel 14, the sealing member 12, the plug 15, and the heating barrel 21 are enclosed within the cavity to form an insulating cavity 33 that surrounds the heating barrel 21. The coil 71 is located within the insulating cavity 33, and the end face of the plug 15 facing the heating barrel 21 in the extension direction of the heating barrel 21 forms a support surface that supports the coil 71. A conductor through-hole (not shown) is provided in the plug 15, and the coil 71 can be electrically connected to the power supply device 104 via a conductor (not shown) in the conductor through-hole, thereby facilitating attachment of the coil 71 to the atomization heating assembly 200.

[0103] In another embodiment, the heat insulating cylinder 14 may be configured as a structure having one open end and one closed end. The mounting base 11 is not provided with a plug 15, and the heat insulating cylinder 14, sealing member 12, and heating cylinder 21 surround each other to form a heat insulating cavity 33. The heat insulating cylinder 14 has a side cylinder wall provided to surround the heating cylinder 21, and further has a bottom cylinder wall provided at a distance from the heating cylinder 21 in the extension direction of the heating cylinder 21, and the inner wall surface of the bottom cylinder wall can form a support surface for supporting the coil 71.

[0104] In some other embodiments, the coil 71 may be disposed outside the thermal insulation cavity 33. For example, the coil 71 is attached to the plug 15 by a fastening or adhesive method, or connected to the outer surface of the bottom wall of the thermal insulation barrel 14. The thermal insulation barrel 14 or the plug 15 is made of a plastic material, which prevents the thermal insulation barrel 14 or the plug 15 from affecting the alternating magnetic field generated after the coil 71 is energized. Furthermore, since the coil 71 is disposed outside the thermal insulation cavity 33, there is no need to provide a through-hole for a conductor in the wall of the thermal insulation cavity 33, which helps ensure the sealing performance of the thermal insulation cavity 33, thereby further reducing heat loss and energy consumption.

[0105] In some embodiments, in the atomization heating assembly 200 employing an electromagnetic induction heating method, at least a portion of the heating barrel 21 may be made of a magnetic material, including a material capable of generating heat in an alternating magnetic field, such as SUS430 or SPCE (semi-cold rolled carbon steel). For example, the side wall 211 of the heating barrel 21 may include a magnetic material, or the bottom wall 212 of the heating barrel 21 may include a magnetic material, or the entire heating barrel 21 may be made of a magnetic material. In this way, after the coil 71 is energized, the heating barrel 21 made of a magnetic material may generate heat locally or entirely in the alternating magnetic field, thereby heating the aerosol product 40.

[0106] In the above embodiment, the coil 71 can generate an alternating magnetic field after being energized, and the heating barrel 21 can generate heat in the alternating magnetic field to heat the airflow and the aerosol product 40. The coil 71 is located on the opposite side of the side wall 211 from the bottom wall 212 of the heating barrel 21 in the extension direction of the heating barrel 21, and the distance between the coil 71 and the bottom wall 212 of the heating barrel 21 is smaller than the distance between the coil 71 and the side wall 211 of the heating barrel 21. Thus, the heat generated by the bottom wall 212 of the heating barrel 21 is higher than that of the side wall 211. Therefore, the bottom wall 212 of the heating barrel 21 is the main heat-generating portion, and the side wall 211 of the heating barrel 21 is an auxiliary heat-generating portion. As a result, the heat generated by the heating barrel 21 is mainly concentrated at the bottom of the heating barrel 21, which reduces the heat transfer toward the aerosol outlet 102 in the extension direction of the heating barrel 21, thereby improving the heat utilization rate of the atomization heating assembly 200.

[0107] In another embodiment, the heating barrel 21 may be made of a thermally conductive ceramic material. The heating structure 50 includes a heating element fixed to the bottom wall 212 and / or the side wall 211 of the heating barrel 21. The heating element is made of a magnetic material and can generate heat in an alternating magnetic field. The heat generated by the heating element can be directly transferred to the airflow in the intake passage 31 and the intake cavity 32, or the heat generated by the heating element can be transferred to the airflow in the intake passage 31 and the intake cavity 32 via the heating barrel 21 to heat the airflow, and the heat generated by the heating element can be transferred to the aerosol product 40 via the heating barrel 21 to heat the aerosol product 40.

[0108] 19 , in some embodiments, in an atomization heating assembly 200, the heating barrel 21 is located within and connected to the thermal insulation barrel 14, and the closed end 215 of the heating barrel 21 is suspended within the thermal insulation barrel 14 and spaced apart from the wall of the thermal insulation barrel 14. The atomization heating assembly 200 further includes a coil winding 81. The coil winding 81 is located outside the thermal insulation barrel 14, and the axis of the coil winding 81 is aligned along the extension direction of the heating barrel 21. The coil winding 81 is used to generate an alternating magnetic field that causes the heating barrel 21 to generate heat.

[0109] 19 , in one embodiment, in an atomizing and heating assembly 200, the heat insulating barrel 14 has a cylindrical structure with both ends open in the extension direction of the heating barrel 21, and the sealing member 12 and plug 15 in the atomizing and heating assembly 200 are sealingly engaged with the openings at both ends of the heat insulating barrel 14. The plug 15 is located on the opposite side of the sealing member 12 from the aerosol outlet 102 provided in the device body 100 in the extension direction of the heating barrel 21, and airflow can pass through the gap between the channel wall of the communication channel 121 in the sealing member 12 and the aerosol product 40 and enter the containing cavity.

[0110] In another embodiment, the insulating barrel 14 may have a cylindrical structure with one open end and one closed end in the extension direction of the heating barrel 21. The insulating barrel 14 includes a side barrel wall and a bottom barrel wall, and the bottom barrel wall is located at the closed end of the insulating barrel 14 in the extension direction of the heating barrel 21. The mounting base 11 includes only the sealing member 12 and the insulating barrel 14, and the sealing member 12 is attached to the open end 214 of the insulating barrel 14 so as to seal.

[0111] The heating barrel 21 is located within the insulating barrel 14, and the outer flange 213 of the heating barrel 21 is fixed so as to be sandwiched between the sealing member 12 and the support arm 141 of the insulating barrel 14 in the extension direction of the heating barrel 21. The side wall 211 and closed end 215 of the heating barrel 21 are both spaced apart from the barrel wall of the insulating barrel 14, forming an insulating cavity 33 surrounding the heating barrel 21 between the insulating barrel 14 and the heating barrel 21. First, the insulating cavity 33 structure is arranged on the outside of the heating barrel 21, which reduces heat loss from the heating barrel 21, improves the thermal utilization rate of the atomization heating assembly 200, and reduces the energy consumption of the non-combustion heating device. Next, by suspending the suspended end of the heating barrel 21 in the insulating cavity 33 in this manner, the heat transferred to the atomization and heating assembly 200 or the device body 100 along the extension direction of the heating barrel 21 in the direction away from the aerosol outlet 102 is reduced, further reducing the heat loss of the heating barrel 21, improving the thermal utilization rate of the atomization and heating assembly 200, and reducing the energy consumption of the non-combustion heating device.

[0112] In some embodiments, the coil winding 81 in the atomization heating assembly 200 is located outside the insulating barrel 14, the axis of the coil winding 81 is aligned with the extension direction of the heating barrel 21, and when energized, the coil winding 81 can generate an alternating magnetic field that heats the heating barrel 21. By using electromagnetic heating in this way to heat the aerosol product 40, it is not necessary to provide a separate conductor in the heating barrel 21 that extends in a direction away from the sealing member 12 in the extension direction of the heating barrel 21. This avoids heat loss in the heating barrel 21 due to transmission along the conductor and avoids increased energy consumption due to current passing through the conductor, thereby improving the thermal utilization rate of the heating barrel 21 and the entire atomization heating assembly 200 and reducing the energy consumption of non-combustion heating devices. Furthermore, since the coil winding 81 is arranged outside the insulating cylinder 14 and has a conductor that is electrically connected to the power supply device 104 in the device body 100, the conductor does not penetrate the cavity wall of the insulating cavity 33, ensuring the sealing performance of the insulating cavity 33 and preventing heat loss due to the flow of air within the insulating cavity 33, thereby further improving the thermal utilization rate of the atomization heating assembly 200 and reducing the energy consumption of the non-combustion heating device.

[0113] 19 , in one embodiment, the coil winding 81 may be fixed to the side barrel wall of the thermal insulation barrel 14 by adhesive or snap connection. The coil winding 81 is disposed coaxially with the thermal insulation barrel 14, thus facilitating assembly of the coil winding 81 in the atomization heating assembly 200.

[0114] In another embodiment, the coil winding 81 is located outside the heat insulating cylinder 14, and the axis of the coil winding 81 and the axis of the heat insulating cylinder 14 may be arranged parallel to or coaxial with each other. For example, the device body 100 may have a support for fixing the atomization and heating assembly 200, and the coil winding 81 may be wound around the support.

[0115] 19 , in one embodiment, the coil winding 81 is arranged to surround the heat insulating cylinder 14. The coil winding 81 may be formed by winding a wire rod having a circular cross section, or may be formed by winding a flat wire rod having a rectangular cross section. The coil winding 81 includes a plurality of coil units 811 arranged along the extension direction of the heating cylinder 21, and each coil unit 811 completely surrounds the heat insulating cylinder 14. The plurality of coil units 811 arranged along the extension direction of the heating cylinder 21 are connected at their leading and trailing ends, and the wire lengths and winding sizes or winding radii of the wire rods of the coil units 811 are all equal, which makes it easy to wind the coil winding 81.

[0116] In some other embodiments, the device body 100 has a support for fixing the atomization heating assembly 200. The coil winding 81 is wound around the support, and the length and winding size of the wire of the multiple coil units 811 in the coil winding 81 may vary depending on the shape of the outer surface of the support that contacts the coil winding 81. For example, the length and winding size of the wire of the multiple coil units 811 in the coil winding 81 may gradually decrease or gradually increase, or may gradually increase and then gradually decrease, from the accommodating cavity toward the communicating channel 121 in the extension direction of the heating barrel 21.

[0117] In one embodiment, the coil winding 81 further includes multiple coil segments arranged in the extension direction of the heating barrel 21. Each coil segment may include one or more coil units 811, with adjacent two coil segments spaced apart in the extension direction of the heating barrel 21. Each coil segment has an external connection terminal for electrical connection to the power supply device 104 in the device main body 100. By controlling the power supply device 104 to supply current to each coil segment, the heating barrel 21 can individually heat different regions in its extension direction, thereby heating each segment of the aerosol product 40. For example, the heating of each coil segment can be sequentially controlled in the extension direction of the heating barrel 21 from the storage cavity to the communication channel 121, thereby ensuring the continuity of the aerosol generated after the aerosol product 40 is heated.

[0118] In another embodiment, the coil winding 81 may be configured to have only a pair of external connection terminals electrically connected to the power supply device 104, thus satisfying the heating needs of the entire heating barrel 21.

[0119] In some embodiments, the heating barrel 21 generates heat under the action of the alternating magnetic field. At least a portion of the heating barrel 21 may be made of a magnetic material. For example, the entire heating barrel 21 may be made of SUS430, SPCE (cold rolled carbon steel for deep drawing), or other material that can generate heat under the action of the alternating magnetic field, so that the entire heating barrel 21 can generate heat under the action of the alternating magnetic field. Alternatively, only the side wall 211 of the heating barrel 21 may be made of a magnetic material so that only the side wall 211 of the heating barrel 21 generates heat under the action of the alternating magnetic field.

[0120] In some other embodiments, a heating element may be fixed to the side wall 211 of the heating barrel 21. The heating element may include a heating wire or a heating film, and the heating element may be made of a magnetic material and fixed to the side wall 211 of the heating barrel 21 by adhesive, so that it can generate heat under the action of an alternating magnetic field.

[0121] In an embodiment in which the heating barrel 21 is the heating element, with reference to FIG. 19, the position of the coil winding 81 in the extension direction of the heating barrel 21 corresponds to the position of the heating barrel 21 in that extension direction. That is, the coil winding 81 is located radially outside the heating barrel 21, and the coil units 811 of the coil winding 81 are arranged at uniform intervals outside the heating barrel 21 in the extension direction of the heating barrel 21, so that the side wall 211 of the heating barrel 21 is located at a position where the magnetic field strength is strong in the coil winding 81, the side wall 211 of the heating barrel 21 forms the main heating part of the heating barrel 21, and the bottom wall 212 of the heating barrel 21 forms the secondary heating part of the heating barrel 21, which can ensure that the side wall 211 of the heating barrel 21 reaches a high temperature under the action of the alternating magnetic field, while the side wall 211 of the heating barrel 21 can heat the substrate segment close to the filter segment in the aerosol product 40, thereby shortening the aerosol generation time and reducing the user's waiting time, contributing to an improved user experience.

[0122] 19 , in one embodiment, the side wall 211 of the heating barrel 21 may be arranged to surround the receiving cavity and be arranged in the extension direction of the heating barrel 21, and the dimension of the side wall 211 of the heating barrel 21 may be equal to or smaller than the dimension of the coil winding 81 in the extension direction of the heating barrel 21, thus reducing the temperature difference of the side wall 211 of the heating barrel 21 in the extension direction of the heating barrel 21 and improving the temperature uniformity of the side wall 211 of the heating barrel 21, thereby contributing to improving the heating uniformity of the aerosol product 40. Of course, in other embodiments, the dimension of the side wall 211 of the heating barrel 21 in the extension direction of the heating barrel 21 may be greater than the dimension of the coil winding 81 in the extension direction of the heating barrel 21.

[0123] The end of the coil winding 81 in the extension direction of the heating barrel 21 that is close to the open end 214 of the heating barrel 21 and the open end 214 of the heating barrel 21 are arranged so as to correspond to each other in the extension direction of the heating barrel 21 and be on the same plane, and the end of the coil winding 81 in the extension direction of the heating barrel 21 that is close to the closed end 215 is arranged so as to be located on the opposite side of the accommodating cavity from the closed end 215 of the heating barrel 21, or the end of the coil winding 81 in the extension direction of the heating barrel 21 that is close to the closed end 215 is arranged so as to be located on the side wall 211 of the heating barrel 21 When the end connected to the bottom wall 212 is positioned so that it corresponds to and is on the same plane in the extension direction of the heating barrel 21, the side wall 211 of the heating barrel 21 is located at a position of strong magnetic field strength in the coil winding 81, and the dimensional requirements for the side wall 211 of the heating barrel 21 and the coil winding 81 in the extension direction of the heating barrel 21 are met.The structure of the coil winding 81 and the heating barrel 21 set in this manner can improve the conversion efficiency between electrical energy in the coil winding 81 and thermal energy in the heating barrel 21.

[0124] An embodiment of the present application further discloses a non-combustion heating device. Referring to Figures 1 to 4, 16, and 19, the non-combustion heating device includes a device main body 100 and any of the above-described embodiments of the atomization and heating assembly 200. The device main body 100 has an aerosol outlet 102 that can communicate with the storage cavity via a communication channel 121 in the atomization and heating assembly 200. The aerosol product 40 can be inserted into the storage cavity from the aerosol outlet 102 along the communication channel 121, and the aerosol generated after the aerosol product 40 is heated can be discharged through the aerosol outlet 102.

[0125] The device main body 100 includes a housing 101 having an attachment cavity therein. The aerosol outlet 102 is provided in the housing 101, and the attachment base 11 is fixed so as to be sandwiched within the attachment cavity in the extension direction of the heating barrel 21. This allows the atomization and heating assembly 200 to be attached and positioned in the device main body 100, and ensures that the communication channel 121 and the aerosol outlet 102 are coaxial.

[0126] The mounting space of the housing 101 includes an atomization cavity, and the atomization and heating assembly 200 is located in the atomization cavity and supported by a support in the housing 101 to realize assembly and fixing of the atomization and heating assembly 200 .

[0127] The device body 100 of the non-combustion heating device further includes a power supply device 104 located in the mounting cavity. The power supply device 104 may be electrically connected to the atomizing heating assembly 200 via an external conductor 22 so as to supply power to the atomizing heating assembly 200 via the power supply device 104. An electrical equipment compartment for mounting the power supply device 104 may be provided separately within the housing 101.

[0128] Although the present invention has been described in detail above using specific examples, the above description is merely for the purpose of aiding understanding of the present invention and is not intended to limit the present invention. Those skilled in the art to which the present invention pertains may make a number of simple deductions, modifications, or substitutions based on the concept of the present invention.
