[0034] The application will be described in further detail below with reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following embodiments, many details are described in order to provide a better understanding of the application. However, those skilled in the art will readily recognize that some features in different embodiments can be omitted, or replaced by other elements, materials, methods, etc. In some cases, some operations related to the application are not shown or described in the specification in order to avoid the core of the application being obscured by too much description, and those skilled in the art will readily recognize that detailed description of these related operations is not necessary in order to fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0035] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that is apparent to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0036] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and have no technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connections (couplings).

[0037] The heating assembly in the heat-not-burn device needs to be able to reach a high temperature in use because it needs to heat the aerosol substrate 900, which also causes the parts in the heat-not-burn device, such as the heating assembly connecting seat 300, which needs to be in contact with the heating assembly, to be made of materials with high-temperature resistance. Materials with high-temperature resistance are usually more expensive, and the material cost is higher.

[0038] In the embodiments of the present application, the heating assembly includes a heating part 100 and an assembly part 200. The assembly part 200 facilitates the assembly of the heating assembly and also helps to prolong the heat conduction path of the heating part 100 to the heating assembly connecting seat 300, that is, to increase the thermal resistance of the heat conduction to the heating assembly connecting seat 300. When the heating assembly heats the aerosol substrate 900, the contact temperature between the seat body connecting part 210 of the heating assembly and the heating assembly connecting seat 300 is reduced, so that the heating assembly connecting seat 300 does not need to use high-temperature-resistant materials, which helps to reduce the material cost.

[0039] In one embodiment, a heating assembly is disclosed. Please refer to Figures 1-5 The heating assembly includes a heating part 100, an assembly part 200, and an electrical connection part 120. The heating part 100 has an insertion end 110 for insertion into the aerosol substrate 900. The assembly part 200 is protruded from the outer peripheral surface of the heating part 100 and is used to cooperate with the heating assembly connecting seat 300 to install and fix the heating assembly. The electrical connection part 120 is connected to the heating part 100 to supply power to the heating part 100.

[0040] In one embodiment, please refer to Figure 1 and Figure 2 The heating part 100 can be a columnar structure with a length direction, and the insertion end 110 is arranged at one end of the heating part 100 along the length direction. In some embodiments, in order to facilitate the insertion of the insertion end 110 into the aerosol substrate 900, the insertion end 110 can be arranged in a conical shape. In other embodiments, the heating part 100 can also be a sheet structure, a tubular structure, or other structure forms, as long as it can be inserted into the aerosol substrate 900 and heated to heat the aerosol substrate 900 to generate aerosol.

[0041] In one embodiment, please refer to Figure 1 and Figure 2The power connection part 120 can be two pins arranged at the end of the heating assembly away from the insertion end 110. The two pins are used to connect with the power supply unit 800 in the heat-not-burn device, so that the power supply unit 800 and the heating part 100 form a loop, so that the power supply unit 800 can supply power to the heating part 100 through the pins, so that the heating part 100 generates heat. In other embodiments, the power connection part 120 can also be a wire, a power connection column or other elements that can achieve electrical connection between the heating part 100 and the power connection part 120.

[0042] In one embodiment, please refer to Figure 1 and Figure 2 The assembly part 200 has a seat connection part 210 for fixedly connecting the heating assembly to the corresponding heating assembly connecting seat 300, and the seat connection part 210 has a spacing with the outer circumferential surface of the heating part 100. For example, the assembly part 200 includes a heating connection part 220 and a seat connection part 210, the heating connection part 220 is connected between the outer circumferential surface of the heating part 100 and the seat connection part 210, so that the seat connection part 210 has a spacing with the outer circumferential surface of the heating part 100. The heat generated by the heating assembly needs to be conducted through the heating connection part 220 to reach the seat connection part 210. Due to the heat loss in the conduction process, the temperature of the seat connection part 210 can be lower than the heat-resistant temperature of conventional plastic materials such as ABS (acrylonitrile-butadiene-styrene copolymer) and PS (polystyrene), so that the heating assembly connecting seat 300 can be made of materials that do not need to withstand high temperature, achieving the effect of reducing material cost.

[0043] In one embodiment, in order to further improve the thermal resistance of the assembly part 200, so that the contact temperature of the seat connection part 210 and the heating assembly connecting seat 300 is reduced. Please refer to Figure 1 and Figure 2 The assembly part 200 has a thinned part, which is located on the side of the seat connection part 210 close to the heating part 100. In some embodiments, the heating connection part 220 can be used as the thinned part, for example, the side of the heating connection part away from the insertion end 110 is flush with the side of the seat connection part away from the insertion end 110, and the thickness of the heating connection part 220 in the length direction of the heating assembly is thinner than the thickness of the seat connection part 210 in the length direction of the heating assembly, so as to reduce the heat conduction width of the heating connection part 220, thereby increasing the thermal resistance of the heat conduction to the seat connection part 210, and further achieving the effect of reducing the contact temperature of the seat connection part 210 and the heating assembly connecting seat 300.

[0044] In one embodiment, please refer to Figure 1 and Figure 2The seat connecting part 210 comprises a main body part 211 and a protruding part 212, the protruding part 212 is protruded on the outer circumferential surface of the main body part 211, and the protruding part 212 is used for clamping and limiting the heating assembly connecting seat 300. For example, the protruding part 212 is arranged at one end of the main body part 211 close to the insertion end 110, and the protruding part 212 is arranged as a convex ring, and the outer circumferential surface of the protruding part 212 and the main body part 211 form a stepped structure, so as to clamp and position the heating assembly connecting seat 300 during assembly.

[0045] In one embodiment, referring to Figure 1 and Figure 2 , the protruding part 212 is provided with a concave cavity 213 close to the heating assembly side, so that the protruding part 212 and the main body part 211 form a stepped structure. The arrangement of the concave cavity 213 helps to reduce the width of the heat conduction path between the main body part 211 and the protruding part 212, increase the thermal resistance, so as to reduce the contact temperature of the seat connecting part 210 and the heating assembly connecting seat 300.

[0046] In one embodiment, referring to Figure 1 , the assembly part 200 has a heat insulation cavity 230. The heat insulation cavity 230 can be the inner cavity of the hole or groove arranged on the surface of the assembly part 200, or can be the cavity arranged inside the assembly part 200. The heat insulation cavity 230 can hinder the heat conduction of the assembly part 200, so that the heat conduction path is lengthened, thereby helping to reduce the contact temperature of the seat connecting part 210 and the heating assembly connecting seat 300.

[0047] In one embodiment, referring to Figure 2 , the assembly part 200 is provided with a heat insulation cavity 230 close to the insertion end 110 and away from the insertion end 110, and the heat insulation cavity 230 close to the heating part 100 and the heat insulation cavity 230 away from the heating part 100 are arranged in staggered manner along the protruding direction of the assembly part 200, so as to lengthen the heat conduction path between the assembly part 200 and the heating assembly connecting seat 300.

[0048] For example, referring to Figure 3 , the assembly part 200 is provided with a heat insulation ring groove on the surface close to the insertion end 110 and the surface away from the insertion end 110, and the projection of the heat insulation ring groove close to the heating part 100 and the heat insulation ring groove away from the heating part 100 intersects in the protruding direction of the assembly part 200, so that the heat conduction path of the part of the assembly part 200 provided with the heat insulation ring groove is in a serpentine shape, and the length is lengthened compared with the heat conduction path along the protruding direction of the assembly part 200, which helps to improve the thermal resistance.

[0049] In one embodiment, the assembly portion 200 is a rotating body structure, and a sealing member 240 is sleeved around the circumference of the assembly portion 200. The sealing member 240 is used to seal with the wall of the mounting cavity 310 on the heating component connection seat 300. Exemplarily, the sealing member 240 is a sealing ring, and an annular recess is provided on the circumference of the main body. The sealing ring is sleeved on the main body and partially locked in the annular recess. The side of the sealing ring facing away from the annular recess is used to abut against the wall of the mounting cavity 310 on the heating component connection seat 300. Therefore, the sealing member 240 not only realizes the sealed assembly of the assembly portion 200 and the heating component connection seat 300, but also helps to reduce the contact area between the seat connection portion 210 and the heating component connection seat 300, thereby increasing the thermal resistance of the heat transfer.

[0050] In other embodiments, the assembly portion 200 may also be formed by a plurality of assembly sub-parts arranged in a scattered manner, so as to achieve assembly and fixation with the heating component connection base 300 .

[0051] To improve the thermal resistance of the assembly portion 200 , in addition to designing the structure of the assembly portion 200 , materials with lower thermal conductivity can also be selected to manufacture the assembly portion 200 .

In some embodiments, the heating portion 100 includes a heating core and a heat-conducting outer shell, and the assembly portion 200 and the heat-conducting outer shell are integrally arranged. The material of the assembly portion 200 and the heat-conducting outer shell can be glass, silica or zirconium oxide, etc., with a thermal conductivity of not higher than 3W / (m·K). In other embodiments, the heating portion 100 and the assembly portion 200 are separately arranged, and the assembly portion 200 can also be a plastic material with a thermal conductivity of not higher than 3W / (m·K), such as ABS (acrylonitrile-butadiene-styrene copolymer), PS (polystyrene) or PC (polycarbonate).

[0053] In one embodiment of a heat-not-burn device, please refer to Figure 3 and Figure 3 Figure 4 Figure 5 The heating without burning device includes a heating component of any one of the above embodiments and a heating component connecting seat 300, and the heating component is installed in the heating component connecting seat 300.

The substrate containing cup 700 is clamped in the mounting cylinder 600, and the cup opening of the substrate containing cup 700 is opposite to the substrate insertion nozzle 500, so that the aerosol substrate 900 can be inserted into the substrate containing cup 700 through the substrate insertion nozzle 500. The end of the substrate containing cup 700 away from the substrate insertion nozzle 500 is provided with a heating part insertion hole 710 and an air inlet hole 720. The heating assembly connecting seat 300 is arranged on the side of the substrate containing cup 700 away from the substrate insertion nozzle 500, and the end of the heating assembly connecting seat 300 close to the substrate containing cup 700 is inserted into the mounting cylinder 600.
