Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or suggesting the quantity or order of the indicated technical features relative to importance or implicitly indicating. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative position relationship or movement between the components under a certain specific posture (as shown in the accompanying drawings), and if the specific posture changes, the directional indication also changes accordingly.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element.

[0048] See also Figure 1 As shown, the present application provides a heating assembly 1 , comprising: a supporting member 11 , a heating member 12 and a sealing member 13 .

[0049] Among them, the support member is a PEEK member, and the support member 11 is concave to form a heating chamber 14. By selecting a peek member to make the support member 11, the support member 11 has good high temperature resistance, high mechanical strength, and is easy to process, and a heating chamber 14 is formed inside the support member 11. It should also be noted that the peek member refers to a component made of peek material, and the peek material is also polyetheretherketone material, which is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy processing, high mechanical strength, corrosion resistance and aging resistance. It can be manufactured and processed into various mechanical parts, for example, it can be used as a support and fixing part of the heating component 1.

[0050] The heating element 12 is connected to the support element 11. By using the support element 11 to support the heating element 12, at least a portion of the heating element 12 blocks at least a portion of the heating cavity 14 formed by the concave portion of the support element 11, making it easy to use the heating element 12 to heat the aerosol generating product contained in the heating cavity 14.

[0051] At least part of the seal 13 is connected to the support 11 to seal the assembly gap of the support 11. By providing the seal 13, the seal 13 is connected to the support 11, and the seal 13 is used to seal the assembly gap of the support 11, which can reduce the heat loss of the heating element 12 when it is working, and reduce the loss of aerosol generated by the aerosol generating product when it is heated.

[0052] In summary, by simplifying the structure and manufacturing process of the heating component 1, the production efficiency is improved, and the heat loss during use and the loss of the generated aerosol are reduced.

[0053] In addition, an aerosol-generating article refers to an article comprising an aerosol-generating substrate, which is intended to be heated rather than burned to release volatile compounds that can form an aerosol, and when heated, the aerosol-generating substrate releases volatile compounds that can form an aerosol. Compared to the aerosol generated by burning or pyrolytic degradation of the aerosol-forming substrate, the aerosol formed by heating the aerosol-forming substrate may contain fewer known harmful ingredients. The aerosol-generating article may be disposable or reusable. The aerosol-forming substrate may be a solid aerosol-forming substrate. Alternatively, the aerosol-forming substrate may include solid and liquid components. The aerosol-forming substrate may include tobacco and / or non-tobacco materials; or the aerosol-forming substrate may include tobacco-containing materials and / or non-tobacco materials; wherein the tobacco-containing material contains volatile tobacco flavor compounds released from the substrate when heated.

[0054] In some embodiments, see Figure 1 and Figure 2 As shown, the heating element 12 may include a first connection portion 121, and the support member 11 includes a second connection portion 111 corresponding to the position of the first connection portion 121.

Exemplarily, the fastener 15 may be a screw, and a through hole 123 may be provided on the first connection member 121, and a fixing hole 113 corresponding to the position of the first connection member 121 may be provided on the second connection member 111; the screw passes through the through hole 123 on the first connection member 121 and is tightened in the fixing hole 113 of the second connection member 111, so that the heating element 12 is fixed to the support member 11.

[0056] Further, the first connecting member 121 can be two extensions 124 arranged on both sides of the heating member 12, and each extension 124 is provided with a through hole 123. The second connecting member 111 is provided with first recessed portions 114 on opposite sides corresponding to the positions of the two extensions 124. The fixing hole 113 can be provided in the first recessed portion 114. A part of the extension 124 can be arranged in the first recessed portion 114, so that the heating body 12 is initially limited by the first recessed portion 114, and then the fastener 15 passes through the through hole 123 on the extension 124 and the fixing hole 113 provided in the first recessed portion 114 in sequence, so as to fix the heating member 12 to the support member 11.

[0057] In some embodiments, see Figures 4 to 8 As shown, the first connection portion 121 may include at least one bending portion 1211 , the support member 11 has a frame structure 112 , and the bending portion 1211 is sleeved on the frame structure 112 , so that the heating element 12 can be fixed by the support member 11 .

[0058] Further, the first connection part 121 may include at least one limiting hole 1212, and the second connection part 111 includes at least one limiting column 1111 corresponding to the position of the limiting hole 1212, and the limiting column 1111 is inserted into the limiting hole 1212 to limit the relative movement between the first connection part 121 and the second connection part 111. Exemplarily, the first connection part 121 may include two bending parts 1211 relatively arranged at opposite ends of the frame structure 112, wherein the limiting hole 1212 is provided on one side of the two bending parts 1211 away from the opening direction of the heating chamber 14, and the second connection part 111 is provided with limiting columns 1111 at positions corresponding to the positions of the two limiting holes 1212, and the two limiting columns 1111 are respectively inserted into the limiting holes 1212, so that the support member 11 can further limit and fix the heating member 12.

[0059] In some embodiments, see Figure 1 , Figure 2 and Figure 3 As shown, the heating element 12 may include a bonding portion 122 , which is suitable for being electrically connected to other heating elements 12 , and the bonding portion 122 is bonded to the support element 11 .

[0060] For further information, see Figure 1 , Figure 2 and Figure 3 As shown, the fitting portion 122 may be provided with a spring piece 1221 , which is suitable for abutting and electrically connecting with other heating elements 12 . Exemplarily, the spring piece 1221 may abut and electrically connect with the spring pieces 1221 on other heating elements 12 .

[0061] In some embodiments, see Figure 1 , Figure 2 and Figure 3 As shown, the heating element 12 may be provided with two fitting portions 122, and the two fitting portions 122 may be relatively arranged at the two ends of the heating element 12. The two extension portions 124 on the heating element 12 may be relatively arranged at the other two ends of the heating element 12. Exemplarily, the two fitting portions 122 may be relatively arranged at the upper and lower ends of the heating element 12, and the two extension portions 124 may be relatively arranged at the left and right ends of the heating element 12. The support member 11 may be provided with first recessed portions 114 corresponding to the positions of the two extension portions 124, and second recessed portions 115 corresponding to the positions of the two fitting portions 122, respectively. Among them, the two extension parts 124 are respectively fixed in the two first recessed parts 114; the two fitting parts 122 are respectively clamped in the two second recessed parts 115, so that the spring piece 1221 on the fitting part 122 can be limited. The setting of the second recessed part 115 can protect the fitting part 122 and the spring piece 1221 thereon to prevent the position of the spring piece 1221 from being displaced or deformed, which is conducive to ensuring that the spring piece 1221 is accurately electrically connected with other heating bodies 12.

[0062] In some other embodiments, see Figures 4 to 8 As shown, the heating element 12 may include two bending portions 1211, the support member 11 has a frame structure 112, the heating element 12 is jacketed on the frame structure 112, and the two bending portions 1211 are respectively located at the two ends of the frame structure 112, so that the support member 11 can fix the heating element 12. The heating element 12 also includes two fitting portions 122, and the two fitting portions 122 are respectively arranged on the two bending portions 1221, and the fitting portion 122 can be arranged on the side of the bending portion 1211 in the same direction as the opening direction of the heating chamber 14, and the fitting portion 122 can be provided with a spring piece 1221. Further, a limiting hole 1212 can be provided on the fitting portion 1221, and the frame structure 112 is provided with a limiting column 1111 corresponding to the position of the limiting hole 1212, and the limiting column 1111 is inserted into the limiting hole 1212 to further fix the heating element 12. The spring piece 1221 and the limiting hole 1212 may be respectively disposed on two opposite sides of the bending portion 1211 , that is, the spring piece 1221 and the limiting column 1111 are oriented in opposite directions.

[0063] For further information, see Figure 6 and Figure 7 As shown, the thickness of the frame with the bending portion 1211 on the frame structure 112 is less than the thickness of the two frames connected to it, so that there is enough thickness space on the frame with the bending portion 1211 to accommodate the bending portion 1211 and the spring piece 1221 thereon, which is beneficial to the coordination between the heating component 1 and other components.

[0064] It is worth noting that the heating element 12 contains conductive materials, such as resistive conductive materials such as iron-chromium-aluminum alloy, nickel-chromium alloy, nickel-iron alloy, platinum, tungsten, silver, etc., which can generate Joule heat when conducting electricity; the heating element 12 is electrically connected to other heating elements 12 through the bonding portion 122, thereby generating Joule heat to heat the aerosol generating product.

[0065] In one example, see Figure 1 , Figure 2 and Figure 3 As shown, the heating element 12 can be constructed as follows Figure 3 In the sheet structure shown, the first connecting parts 121 are provided at opposite ends of the heating element 12, and the first connecting parts 121 are connected to the second connecting parts 111 arranged oppositely on the support member 11 through fasteners 15, so that the heating element 12 is fixed on the support member 11; the heating element 12 includes a fitting part 122, and the fitting part 122 is provided at opposite ends of the heating element 12 where the first connecting part 121 is not provided, and a spring 1221 is provided on the fitting part 122, and the spring 1221 is in electrical contact with the spring 1221 on other heating elements 12 to realize the transmission of current, so that the heating element 12 generates Joule heat. The thermal simulation experiment test shows that the temperature of the low-temperature area at the edge of the heating element 12 is only about 20°C different from the temperature of the high-temperature area in the center, thereby ensuring the uniformity of the temperature of the heating element 12 during the heating process.

[0066] In another example, see Figures 4 to 10 As shown, the heating element 12 is constructed as follows Fig. 9 , Fig.10 In the sheet structure shown, the first connecting parts 121 arranged at the opposite ends of the heating element 12 are bent inward to form bending parts 1211, and the bending parts 1211 are clamped on the frame structure 112 of the support member 11, and the relative movement between the first connecting part 121 and the second connecting part 111 is limited by the plug-in cooperation between the limiting hole 1212 arranged on the first connecting part 121 and the limiting column 1111 arranged on the second connecting part 111; the heating element 12 includes a relatively arranged fitting part 122, the fitting part 122 is arranged on the side of the bending part 1211 and the opening direction of the heating chamber 14 in the same direction, and a spring piece 1221 is provided on the fitting part 122, and the spring piece 1221 is electrically contacted with the spring piece 1221 on the other heating element 12 to realize the transmission of current, so that the heating element 12 generates Joule heat. The heating element 12 can effectively increase the length of the heating path through multiple bends and turns, thereby increasing the contact area between the high-temperature area and the aerosol generating product. Thermal simulation experimental tests show that the contact area between the high-temperature area of ​​the heating element 12 and the solid substrate is increased, the effective heating area of ​​the heating element 12 is above 80%, and the uniformity of the heating temperature field can be ensured.
