Abstract

This application relates to the field of heated non-combustible technology, specifically to a heating component and a heated non-combustible device. The heating component includes a cylinder, a first heating element, and a second heating element. The cylinder contains a matrix section for accommodating the aerosol product. The cylinder has a first section and a second section arranged coaxially. The first section is located on the side of the second section facing the nozzle section. The first section and the matrix section are spaced apart. The first heating element is located radially outside the first section, and the second heating element is located radially outside the second section. During the preheating stage, the second heating element does not work, and only the first heating element transfers heat to the matrix section through the first section. This can shorten the preheating time of the matrix section and reduce the heat transfer efficiency between the first section and the matrix section through the gap between them, thereby reducing the temperature of the matrix section. This can reduce the probability of the matrix section paper tube being over-baked and producing a pasty smell due to high temperature, thus helping to improve the user experience.

Description

Technical Field

[0001] This application relates to the field of heat-not-burning technology, specifically to a heating component and a heat-not-burning device. Background Technology

[0002] Heated non-combustible devices typically include a heating element, which is used to heat aerosol products to generate aerosols. The heating method of the heating element includes central heating and circumferential heating. The heating element of the circumferential heating method typically includes a heating cylinder. The aerosol product is inserted into the heating cylinder, and the cylinder wall is in contact with the outer circumferential surface of the aerosol product. The heat of the heating element can be directly transferred to the aerosol product through the heating cylinder to achieve heating of the aerosol product.

[0003] Aerosol products typically consist of a nozzle section and a matrix section. Both the nozzle section and the matrix section are covered with paper tubes. During the use of the heat-not-burning device, the heat from the heating element is transferred to the aerosol matrix sequentially through the heating cylinder and the paper tube of the matrix section. When the paper tube is at a high temperature, it will produce a pasty smell, which will affect the user's experience. Utility Model Content

[0004] This application provides a heating component and a non-combustible heating device to solve the problem that the non-combustible heating device produces a papery smell during use, which affects the user experience.

[0005] According to one aspect of this application, one embodiment provides a heating assembly, comprising:

[0006] A cylindrical body for containing a matrix section of an aerosol product, the cylindrical body having a first section and a second section coaxially arranged in its extending direction, the first section being located on the side of the second section facing the nozzle section of the aerosol product, the first section being spaced apart from the matrix section.

[0007] A first heating element is located radially outside the first section of the cylinder to transfer heat to the matrix section through the first section during the preheating stage;

[0008] The second heating element is located radially outside the second section of the cylinder, and the second heating element only transfers heat to the matrix section through the second section during the suction phase.

[0009] In an optional embodiment, the heating assembly further includes a heat transfer element for surrounding the matrix section and arranged radially with the second section in the cylinder, wherein the second heating element transfers heat to the matrix section through the heat transfer element and the second section during the suction phase.

[0010] In one alternative embodiment, the inner diameter of the first segment is larger than the inner diameter of the second segment, the second segment is used to fit against the matrix segment, the heat transfer element is arranged around the second segment, and the second heating element is located on the side of the heat transfer element opposite to the second segment in the radial direction of the cylinder.

[0011] In one alternative embodiment, the cylinder has a connecting section connecting the first section and the second section, and the heat transfer element abuts against the connecting section in the extending direction of the cylinder.

[0012] In one alternative embodiment, the thermal conductivity of the heat transfer element is less than or equal to 8 W / (m·K).

[0013] In one alternative embodiment, the heat transfer element comprises a ceramic shell or a glass shell.

[0014] In one alternative embodiment, the second heating element includes a second heating film, which is fixed radially to the outer peripheral surface of the heat transfer element or the second segment.

[0015] In one alternative embodiment, the first heating element includes a first heating film, which is fixed radially to the outer peripheral surface of the first segment.

[0016] In one alternative embodiment, the first heating element includes a coil arranged around the first segment, the coil being energized to generate an alternating magnetic field that heats the first segment.

[0017] According to one aspect of this application, one embodiment provides a heating non-combustible device, including a device body and a heating component as described in any of the above claims, wherein the heating component is clamped and fixed in the device body in the extending direction of the cylinder, and the device body has an opening that is coaxially connected to the internal space of the cylinder.

[0018] According to the heating assembly and the heated non-combustible device of the above embodiments, since the first section of the cylinder in the heating assembly is located on the side of the second section facing the nozzle section of the aerosol product, and the first section is arranged at an interval from the matrix section, the second heating element does not work during the preheating stage, and only the first heating element transfers heat to the matrix section through the first section. This can shorten the preheating time of the matrix section, and the heat transfer efficiency between the first section and the matrix section can be reduced by the gap between the first section and the matrix section, thereby reducing the temperature of the matrix section. This can reduce the probability that the high temperature will cause the paper tube of the matrix section to be over-baked and produce a papery smell, which helps to improve the user experience.

[0026] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0027] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0028] This application discloses a heating component, which is used in a heating non-combustible device to heat aerosol products.

[0029] Before introducing the structure of the heating component of this application, the heating process of the heating non-combustible device and the general structure of the aerosol product will be introduced first.

[0030] The heating process of aerosol products by the heated non-combustible device includes a preheating stage and an aspiration stage. In the preheating stage, the temperature of the aerosol product continuously rises, generating and accumulating aerosols to ensure the aerosol concentration of the first breath in the subsequent aspiration stage. Therefore, the preheating stage is also the aspiration waiting stage. The aspiration stage begins when the user starts taking the first breath.

[0031] Please refer to Figure 2 The aerosol product 1 generally includes a matrix section 11, a cooling section 12, and a nozzle section 13. The cooling section 12 is located between the nozzle section 13 and the matrix section 11. The matrix section 11 contains an aerosol matrix that generates aerosols after heating. The nozzle section 13 is located at the end of the aerosol product 1 along its length. During the use of the heatless non-combustible device, the matrix section 11 of the aerosol product 1 is inserted into the heatless non-combustible device, and the nozzle section 13 is located outside the heatless non-combustible device. During the heating process, the user's lips wrap around the nozzle section 13, and the aerosol generated by the matrix section 11 can be drawn out.

[0032] Please refer to Figures 1 to 5 The heating component 3 in this embodiment includes a cylinder 31, a first heating element 33, and a second heating element 34. During the use of the heating non-combustible device, the extension direction of the aerosol product 1 is the same as the extension direction of the cylinder 31. The cylinder 31 is arranged around the matrix section 11 of the aerosol product 1. The internal space of the cylinder 31 forms a receiving cavity for accommodating the aerosol product 1. The suction nozzle section 13 is located outside the cylinder 31.

[0033] The cylinder 31 has an inlet end 311 and an outlet end 312 located at both ends in its extending direction. After the aerosol product 1 is inserted into the cylinder 31, the outlet end 312 is located between the inlet end 311 and the nozzle section 13 in the extending direction of the cylinder 31. The cylinder 31 also has a first section 313 and a second section 314 arranged coaxially in its extending direction. The first section 313 and the second section 314 are respectively close to or located at both ends of the cylinder 31 in its extending direction. The first section 313 is located between the nozzle section 13 and the second section 314 in the extending direction of the cylinder 31. That is, the first section 313 is close to or located at the outlet end 312 of the cylinder 31 in the aerosol discharge direction, and the second section 314 is close to or located at the inlet end 311 of the cylinder 31 in the aerosol discharge direction. The cross-sectional shape of the first section 313 and the second section 314 in the direction perpendicular to the extending direction of the cylinder 31 can be a cylindrical structure, or it can be other structures adapted to the cross-sectional shape of the aerosol product 1. The inner diameter of the first segment 313 can be larger than the radial dimension of the aerosol product 1. After the aerosol product 1 is inserted into the accommodating cavity, the first segment 313 and the matrix segment 11 are arranged at intervals.

[0034] The first heating element 33 is located radially outside the first section 313 of the cylinder 31. The first heating element 33 generates heat when energized, or the first heating element 33 causes the corresponding first section 313 to generate heat when energized. The first heating element 33 can transfer heat to the substrate section 11 through the first section 313 during the preheating stage to heat the substrate section 11 and generate aerosol. Since the first section 313 is close to or located at the air outlet 312 of the cylinder 31, this structure of the first heating element 33 heating the substrate section 11 through the first section 313 during the preheating stage helps to shorten the preheating stage time and the user's suction waiting time. Furthermore, since the first section 313 and the substrate section 11 are arranged at intervals, the heat transfer efficiency between the first section 313 and the substrate section 11 can be reduced by utilizing the gap between the first section 313 and the substrate section 11, thereby reducing the temperature of the substrate section 11 during the preheating stage and reducing the probability of the substrate section 11 paper tube being over-baked and producing a papery smell due to high temperature, which helps to improve the user experience.

[0035] The second heating element 34 is located radially outside the second section 314 of the cylinder 31. The second heating element 34 generates heat when energized, or the second heating element 34 causes the corresponding second section 314 to generate heat when energized. The second heating element 34 does not participate in the heating during the preheating stage. The second heating element 34 only transfers heat to the matrix section 11 through the second section 314 during the suction stage. That is, during the suction stage, only the second heating element 34 works, or both the second heating element 34 and the first heating element 33 work. This helps to ensure the heating efficiency during the suction stage and helps to ensure the complete combustion of the aerosol product 1.

[0036] In some embodiments, please refer to Figures 2 to 5The cylinder 31 can be integrally formed and made of metal material, such as 430 stainless steel or 316 stainless steel. The first heating element 33 is a heat source and heats the substrate section 11 by direct heat transfer. The first heating element 33 includes a first heating film. The first heating film is fixed to the outer circumferential surface of the first section 313 in the radial direction of the cylinder 31 by adhesive. The heat generated by the first heating film after being energized is directly transferred to the first section 313 and then to the substrate section 11 through the gap between the first section 313 and the substrate section 11.

[0037] In some embodiments, the first heating element 33 may also employ electromagnetic heating. The first heating element 33 includes a coil arranged around the first segment 313. The coil may be wound around the outer circumferential surface of the first segment 313. An insulator may be provided between the coil and the first segment 313 to ensure that the cylinder 31 is not energized when the coil is energized. The first segment 313 and the second segment 314 in the cylinder 31 may be configured as separate structures. The heat source is the first segment 313. The first segment 313 of the cylinder 31 is made of a magnetically conductive material, such as 430 stainless steel. The second segment 314 may be made of other non-magnetically conductive metal materials. At least a portion of the first segment 313 is inserted into or fitted with at least a portion of the second segment 314. When the coil is energized, an alternating magnetic field is generated. Only the first segment 313 can generate heat in the alternating magnetic field. The heat can be transferred to the matrix segment 11 through the gap between the first segment 313 and the matrix segment 11, thereby heating the matrix segment 11.

[0038] In some embodiments, please refer to Figures 2 to 5 To reduce the probability of a papery smell during the suction stage, the heating assembly 3 also includes a heat transfer element 32. The heat transfer element 32 and the second section 314 are arranged radially in the cylinder 31. During the heating of the matrix section 11, the heat transfer element 32 is arranged around the matrix section 11. The second heating element 34 transfers heat to the matrix section 11 through the heat transfer element 32 and the second section 314. The arrangement of the heat transfer element 32 helps to increase the distance between the second heating element 34 and the matrix section 11, reduce the heat transfer efficiency between the second heating element 34 and the matrix section 11, thereby reducing the temperature of the matrix section 11 during the suction stage and reducing the probability of a papery smell during the suction stage.

[0039] Of course, in other embodiments, in order to reduce the probability of paper paste smell during the suction stage, the heat transfer element 32 may not be provided. The inner diameter of the second segment 314 is larger than the outer diameter of the matrix segment 11. The second segment 314 and the matrix segment 11 are arranged at intervals. During the suction stage, the first heating element 33 heats the matrix segment 11 through the first segment 313, and the second heating element 34 heats the matrix segment 11 through the second segment 314. The gap between the first segment 313 and the matrix segment 11 and the gap between the second segment 314 and the matrix segment 11 reduce the heat transfer efficiency between the first segment 313 and the second segment 314 and the matrix segment 11, respectively, thereby reducing the temperature of the matrix segment 11 during the suction stage, reducing the probability of the paper tube being over-baked and producing a paper paste smell, and improving the user experience.

[0040] In some embodiments, the heating assembly 3 includes the heat transfer element 32 described above. The heat transfer element 32 is located radially outside the second section 314 of the cylinder 31. The inner diameter of the second section 314 may be equal to or greater than the outer diameter of the matrix section 11.

[0041] Please refer to Figures 2 to 5 In one embodiment, the inner diameter of the first segment 313 is larger than the inner diameter of the second segment 314, and the inner diameter of the second segment 314 is equal to the outer diameter of the matrix segment 11. The heat transfer element 32 is a cylindrical structure, fitted around the second segment 314, and arranged around the second segment 314, which is in contact with the matrix segment 11. The second heating element 34 includes a second heating film, which is fixed radially on the outer circumferential surface of the heat transfer element 32; alternatively, the second heating element 34 may include a heating wire, which is wound around the outside of the heat transfer element 32. During the suction stage, the second heating element 34 is energized, and the heat from the second heating element 34 is transferred to the matrix segment 11 sequentially through the heat transfer element 32 and the second segment 314. The heat transfer efficiency between the second heating element 34 and the second segment 314 can be reduced by the heat transfer element 32, thereby reducing the temperature of the matrix segment 11 during the suction stage and further reducing the probability of generating a papery smell during the suction stage.

[0042] Of course, in some embodiments, the inner diameter of the second segment 314 can be larger than the outer diameter of the matrix segment 11. The second segment 314 and the matrix segment 11 are arranged at intervals. The heat transfer element 32 is fitted outside the second segment 314. After the second heating element 34 is powered on, the heat of the second heating element 34 is transferred to the matrix segment 11 in sequence through the heat transfer element 32, the second segment 314, and the gap between the second segment 314 and the matrix segment 11. On the one hand, the heat transfer efficiency between the second heating element 34 and the second segment 314 can be reduced by the heat transfer element 32. On the other hand, the heat transfer efficiency between the second segment 314 and the matrix segment 11 can also be reduced by the gap between the second segment 314 and the matrix segment 11, thereby reducing the temperature of the matrix segment 11 in the suction stage, further reducing the probability of paper paste smell in the suction stage, and even avoiding the generation of paper paste smell in the suction stage.

[0043] In some embodiments, the heating assembly 3 includes the heat transfer element 32 described above. The inner diameter of the second segment 314 is greater than the outer diameter of the matrix segment 11. The heat transfer element 32 is located radially between the second segment 314 and the matrix segment 11 in the cylinder 31. The inner diameter of the heat transfer element 32 may be greater than or equal to the outer diameter of the matrix segment 11. The outer diameter of the heat transfer element 32 is greater than the inner diameter of the first segment 313. The second heating element 34 can be heated electromagnetically. The second heating element 34 includes a coil arranged around the second section 314. The coil is insulated from the second section 314. The second section 314 of the cylinder 31 is made of a magnetically conductive material. The second section 314 is a heat source. When the coil is energized, it generates an alternating magnetic field. The second section 314 can generate heat under the alternating magnetic field. In the embodiment where the heat transfer element 32 is attached to the substrate section 11, the heat of the second section 314 is transferred to the substrate section 11 through the heat transfer element 32 to heat the substrate section 11. Alternatively, in the embodiment where the heat transfer element 32 and the substrate section 11 are spaced apart, the heat of the second section 314 is transferred to the substrate section 11 sequentially through the heat transfer element 32 and the gap between the heat transfer element 32 and the substrate section 11 to heat the substrate section 11. The heat transfer efficiency between the second section 314 and the matrix section 11 can be reduced by the heat transfer element 32, or the heat transfer efficiency between the second section 314 and the matrix section 11 can be reduced by both the heat transfer element 32 and the gap between the heat transfer element 32 and the matrix section 11. This reduces the temperature of the matrix section 11 during the suction stage, reduces the probability of paper paste smell during the suction stage, and may even prevent paper paste smell from being generated during the suction stage, thereby improving the user experience.

[0044] In some embodiments, the heat transfer element 32 is located radially between the second section 314 and the substrate section 11 of the cylinder 31. The second heating element 34 includes a second heating film, which is fixed to the outer peripheral surface of the second section 314 by adhesive. The heat generated by the second heating film when energized can be directly transferred to the second section 314, and then transferred to the heat transfer element 32. In embodiments where the heat transfer element 32 is attached to the substrate section 11, the heat transfer element 32 then transfers the heat to the substrate section 11 to heat the substrate section 11. Alternatively, in embodiments where the heat transfer element 32 and the substrate section 11 are spaced apart, The heat transferred from the second section 314 to the heat transfer element 32 is then transferred to the substrate section 11 through the heat transfer element 32 and the gap between the heat transfer element 32 and the substrate section 11, thereby heating the substrate section 11. In this way, the heat transfer efficiency between the second section 314 and the substrate section 11 can be reduced by the heat transfer element 32, or the heat transfer efficiency between the second section 314 and the substrate section 11 can be reduced by both the heat transfer element 32 and the gap between the heat transfer element 32 and the substrate section 11. This reduces the temperature of the substrate section 11 during the suction stage, reduces the probability of paper paste smell during the suction stage, and may even prevent the paper paste smell from being generated during the suction stage.

[0045] In some embodiments, the heat transfer element 32 may extend to the first section 313 in the extending direction of the cylinder 31. The heat transfer element 32 is located on the radial outer side of the cylinder 31. The first heating element 33 includes a first heating film, which is fixed on the radial outer side of the heat transfer element 32. After the first heating element 33 is heated, the heat is transferred to the matrix section 11 in sequence through the heat transfer element 32, the first section 313, and the gap between the first section 313 and the matrix section 11. In the preheating stage, the heat transfer efficiency between the first heating element 33 and the matrix section 11 can be reduced through the gap between the heat transfer element 32 and the first section 313 and the matrix section 11, thereby reducing the temperature of the matrix section 11, reducing the probability of paper paste smell in the preheating stage, or even avoiding the generation of paper paste smell in the preheating stage. Of course, if the first heating element 33 participates in the heating of the suction stage, the heat transfer efficiency between the first heating element 33 and the matrix section 11 can be reduced by the gap between the heat transfer element 32 and the first section 313 and the matrix section 11, thereby reducing the temperature of the matrix section 11 and reducing the probability of paper paste smell being generated during the suction stage.

[0046] In some embodiments, the heat transfer element 32 may also be disposed inside the cylinder 31, with the heat transfer element 32 and the substrate section 11 arranged at intervals. The heat transfer element 32 at the first section 313 is located between the first section 313 and the substrate section 11. The first heating element 33 includes a first heating film, which is fixed to the outside of the first section 313. When the first heating element 33 is working, the heat from the first heating element 33 is transferred to the substrate section 11 sequentially through the first section 313, the heat transfer element 32, and the gap between the heat transfer element 32 and the substrate section 11, thereby reducing the temperature of the substrate section 11 and decreasing the probability of generating a papery smell during the preheating stage. Alternatively, when the first heating element 33 participates in the heating during the suction stage, it can also reduce the probability of generating a papery smell during the suction stage. In other embodiments, the heat transfer element 32 may also be attached to the substrate section 11. When the first heating element 33 is working, the heat transfer efficiency between the first heating element 33 and the substrate section 11 is reduced only through the heat transfer element 32, thereby reducing the probability of generating a papery smell and improving the user experience.

[0047] In some embodiments, the heat transfer element 32 is provided only at the second segment 314, and the cylinder 31 has a connecting segment 315 that connects the first segment 313 and the second segment 314. For example, please refer to [reference needed]. Figures 2 to 5The inner diameter of the first section 313 is larger than the inner diameter of the second section 314. The inner diameter of the second section 314 is equal to or slightly larger than the outer diameter of the matrix section 11. The heat transfer element 32 is fitted into the second section 314. The inner diameter of the heat transfer element 32 is smaller than the outer diameter of the first section 313. After the heat transfer element 32 is fitted into the second section 314, it can abut against the connecting section 315 in the extending direction of the cylinder 31. This facilitates the positioning of the heat transfer element 32 in the heating assembly 3. After the heating assembly 3 is installed in the heating non-combustible device, it can prevent the heat transfer element 32 from shaking in the extending direction of the cylinder 31, which helps to improve the structural stability of the heating assembly 3 and the entire heating non-combustible device.

[0048] In one embodiment, the inner diameter of the first segment 313 is smaller than the inner diameter of the second segment 314. The heat transfer element 32 is located on the inner side of the second segment 314 in the radial direction of the cylinder 31. The outer diameter of the heat transfer element 32 is larger than the inner diameter of the first segment 313. After the heat transfer element 32 is inserted into the second segment 314, the heat transfer element 32 can abut against the connecting segment 315 in the extending direction of the cylinder 31. This facilitates the positioning of the heat transfer element 32 in the heating assembly 3. After the heating assembly 3 is installed in the heating non-combustible device, the heat transfer element 32 can be prevented from shaking in the extending direction of the cylinder 31, which helps to improve the structural stability of the heating assembly 3 and the entire heating non-combustible device.

[0049] In some embodiments, please continue to refer to Figures 2 to 5 To increase the impact of heat transfer element 32 on heat transfer efficiency, the thermal conductivity of heat transfer element 32 is set to be less than or equal to 8 W / (m·K). For example, the thermal conductivity of heat transfer element 32 can be set to 8 W / (m·K), 7 W / (m·K), or even 5 W / (m·K). By using heat transfer element 32 with a smaller thermal conductivity, the heat transfer efficiency between the second section 314 and the matrix section 11 can be further reduced. Alternatively, when heat transfer element 32 is set at the position of the first section 313, the heat transfer efficiency between the first section 313 and the matrix section 11 can also be reduced, thereby further reducing the temperature of the matrix section 11 and further reducing the probability of generating a paper paste smell during the suction stage or the entire heating stage. It can even prevent the generation of a paper paste smell during the suction stage or the entire heating stage.

[0050] Of course, in other embodiments, the thermal conductivity of the heat transfer element 32 can be set to be greater than 8W / (m·K), such as 9W / (m·K) or 15W / (m·K), as long as the heat transfer element 32 can reduce the heat transfer efficiency between the second section 314 or the second heating element 34 and the matrix section 11.

[0051] In some embodiments, the heat transfer element 32 is a cylindrical shell structure for the entire heat transfer element 32. The heat transfer element 32 may be made of a ceramic material with a low thermal conductivity to form a ceramic shell, such as a zirconium oxide material, or it may be made of a glass material to form a glass shell, such as a quartz glass material, or it may be made of other materials with low thermal conductivity, which will not be listed here.

[0052] This application also provides a heating non-combustible device; please refer to [reference needed]. Figure 1 and Figure 2 The heating non-combustible device includes a device body 2 and a heating component 3 in any of the above embodiments. The heating component 3 is clamped and fixed in the device body 2 in the extending direction of the cylinder 31. In the embodiment where heat transfer elements 32 are provided at both the first section 313 and the second section 314, the cylinder 31 and the entire heat transfer element 32 are clamped and fixed in the device body 2 in the extending direction of the cylinder 31.

[0053] The main body 2 of the device includes a housing 21 and a support assembly 22 installed inside the housing 21. The control assembly 4 and the battery 5 are both located inside the housing 21 and installed on the support assembly 22. The first heating element 33 and the second heating element 34 are electrically connected to the control assembly 4, and the first heating element 33 and the second heating element 34 can be independently controlled to work by the control assembly 4. The housing 21 has an opening 211 that communicates with its internal space. After the cylinder 31 of the heating assembly 3 or the cylinder 31 and the heat transfer element 32 are clamped and fixed in the support assembly 22, the port of the first section 313 of the cylinder 31 communicates with the opening 211, and the aerosol product 1 can be inserted into the cylinder 31 through the opening 211.

[0054] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention.
