[0028] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] 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).

[0031] In related technologies, heated non-combustible devices include circumferential oxygen-free heating methods, where a rod-shaped aerosol matrix is ​​inserted into the receiving cavity of a heating component, and the aerosol matrix is ​​heated through heat conduction. To ensure smooth insertion of the aerosol into the receiving cavity, one method involves leaving a gap between the aerosol matrix and the cavity wall. This results in poor contact between the aerosol matrix and the heating component, affecting the heat conduction efficiency and requiring a longer preheating time for the aerosol matrix.

[0032] This application modifies the shape of the cavity wall to create a curved wall for compressing the aerosol matrix. The cross-sectional profile of the cavity corresponds to a curved section that bulges towards the center of the cavity. When the aerosol matrix is ​​inserted, the curved wall of the cavity compresses the aerosol matrix, causing it to deform. The deformed aerosol matrix has a portion that stably adheres to the cavity wall, which helps improve poor contact between the aerosol matrix and the heating element, increases the heat transfer efficiency between them, and shortens the preheating time of the aerosol matrix.

[0033] The following describes some embodiments of the heating assembly provided in this application with reference to the accompanying drawings.

[0034] Please see Figures 1 to 6 This application provides a heating assembly, including a heating element 1 and other functional components as needed, which will be described in detail below.

[0035] In this embodiment, the heating element 1 is provided with a receiving cavity 101 for accommodating the aerosol matrix 4. The receiving cavity 101 is provided with an insertion port 102 for inserting the aerosol matrix 4. The cavity wall of the receiving cavity 101 has a curved wall 103 for extruding the aerosol matrix 4. The cross-sectional profile of the receiving cavity 101 and the part corresponding to the curved wall 103 are curved and protrude towards the center of the receiving cavity 101. The cross-section is a section perpendicular to the axial direction of the receiving cavity 101.

[0036] It is understood that the heating element 1 in this embodiment is a component that can be heated, and it can be made of a metal material with good thermal conductivity, such as any one of steel, copper, aluminum, and their alloys. This embodiment does not limit the specific heating method of the heating element 1; for example, it can be electromagnetic induction heating or resistance heating. The aerosol matrix 4 in this embodiment can be a rod-shaped aerosol matrix 4, for example, but not limited to, a cigarette. The aerosol matrix 4 can be inserted into the receiving cavity 101 only when in use; when not in use, the receiving cavity 101 may not contain the aerosol matrix 4. The curved wall 103 in this embodiment can be a partially cylindrical surface, a surface of revolution, or a quadratic surface, or other curved surfaces besides these, allowing the aerosol matrix 4 to be smoothly inserted into the receiving cavity 101 and to be compressible. Because curved surfaces have a smooth characteristic, the curved wall 103 can provide good guidance for the deformation of the aerosol matrix 4 when it is compressed. In this embodiment, the cross-sectional profile of the receiving cavity 101 and the portion corresponding to the curved wall 103 are curved and bulge towards the center of the receiving cavity 101. This bulging structure is more conducive to the conduction of heat to the center of the aerosol matrix 4. Figure 4 , Figure 5 As shown, after the aerosol matrix 4 is compressed, the protruding curved wall 103 is closer to the central axis of the aerosol matrix 4, thereby reducing the heat conduction distance of the middle part of the aerosol matrix 4 and shortening the preheating time of the middle part of the aerosol matrix 4. In this embodiment, the axial direction of the receiving cavity 101 is parallel to the insertion direction of the aerosol matrix 4.

[0037] In the heating assembly of this embodiment, the cavity wall of the receiving cavity 101 has a curved wall 103 for compressing the aerosol matrix 4. The cross-sectional profile of the receiving cavity 101 and the portion corresponding to the curved wall 103 are curved and protrude towards the center of the receiving cavity 101. When the aerosol matrix 4 is inserted, the curved wall 103 of the receiving cavity 101 compresses the aerosol matrix 4, causing the aerosol matrix 4 to deform. The deformed aerosol matrix 4 has a portion that stably fits against the cavity wall of the receiving cavity 101, which helps to improve the poor contact between the aerosol matrix 4 and the heating assembly, improves the heat conduction efficiency between the aerosol matrix 4 and the heating assembly, and helps to shorten the preheating time of the aerosol matrix 4.

[0038] In one embodiment, the cross-sectional profile of the receiving cavity 101 is polygonal, with each side of the polygon having a curve protruding towards the center of the receiving cavity 101. The receiving cavity 101 as a whole is a polygonal prism, with each side of the polygon having a curve protruding towards the center of the receiving cavity 101; that is, each prism face of the prism-shaped receiving cavity 101 has a curved wall 103. This structure of the receiving cavity 101 facilitates stable contact between the cavity wall of the receiving cavity 101 and the aerosol matrix 4, and the polygonal shape provides good compression of the aerosol matrix 4, which helps to reduce the distance between the cavity wall of the receiving cavity 101 and the center of the aerosol matrix 4, thus shortening the preheating time of the aerosol matrix 4. In some embodiments, the cross-sectional profile of the receiving cavity 101 can be triangular, rectangular, pentagonal, etc.; when it is triangular, it can be an equilateral triangle; when it is rectangular, it can be a square; and when it is pentagonal, it can be a regular pentagon. In some embodiments, the cross-sectional profile of the receiving cavity 101 can also be other shapes besides polygons, such as an ellipse. In some application scenarios, the cross-sectional profile of the receiving cavity 101 is polygonal. Only some of the sides of the polygon may have curves protruding towards the center of the receiving cavity 101, while the remaining sides are set as straight lines. For example, when the cross-sectional profile of the receiving cavity 101 is rectangular, two opposite sides of the rectangle may both be curves, and two opposite sides may both be straight lines.

[0039] In one embodiment, such as Figure 3 , Figure 6 As shown, the cross-sectional profile of the receiving cavity 101 is rectangular, and the two opposite sides of the rectangle combine to form a hyperbola. The hyperbola shape provides symmetry, which is beneficial for the uniform heating of the aerosol matrix 4. In some embodiments, to further ensure uniform heating of the aerosol matrix 4, the hyperbola formed by one pair of opposite sides of the rectangle can be the same as or approximately the same as the hyperbola formed by the other pair of opposite sides. In some embodiments, the cross-sectional profile of the receiving cavity 101 is rectangular, and the sides of the rectangle can also be set as the same arc, or the sides of the rectangle can be set as different curves.

[0040] In one embodiment, such as Figure 5 As shown, in any two adjacent sides of a polygon, the curve of one side connects to the curve of the other side via an arc, forming an airflow space 104 at the corner of the polygon. The arc connection facilitates the cleaning of the receiving cavity 101, and the airflow space 104 at the corner improves airflow permeability. This embodiment does not limit the specific size of the airflow space 104; it can be set as needed. In some embodiments, the curve of one side of any two adjacent sides of the polygon can also connect to the curve of the other side via a straight line. In some application scenarios, the airflow space 104 may not be provided at the corner of the polygon; instead, the outline of the corner can be directly set as the outer outline of the corner corresponding to the corner after the aerosol matrix 4 is compressed and deformed.

[0041] In one embodiment, such as Figure 2 As shown, the heating element 1 has a cylindrical structure with openings at both ends. One end of the heating element 1 is an inlet 102, and the end of the heating element 1 away from the inlet 102 is provided with a base 3, which seals and covers the other end opening of the heating element 1. The cylindrical structure of the heating element 1 with openings at both ends simplifies its manufacturing and facilitates processing. The base 3 seals and covers the other end opening of the heating element 1, enabling oxygen-free heating of the aerosol matrix 4. In some embodiments, the heating element 1 can also be directly manufactured as a one-piece structure with a closed bottom. This embodiment does not limit the specific shape of the base 3, as long as it can seal and cover the other end opening of the heating element 1. In some embodiments, the base 3 can serve to fix and support the heating element 1. For example, the base 3 can be connected to the inner support 6 of the heating non-combustible device, and the heating element 1 can be connected to the inner support 6 through the base 3.

[0042] In one embodiment, such as Figure 1 , Figure 2 As shown, the heating assembly also includes a bracket 2, with the heating element 1 installed inside the bracket 2. The bracket 2 has a guide hole 201 corresponding to the insertion port 102. The guide hole 201 has a guide slope 202 for guiding the aerosol matrix 4 into the receiving cavity 101. The wall of the guide hole 201 has a sloping curved wall for pre-compressing the aerosol matrix 4. The cross-sectional profile of the guide hole 201 and the part corresponding to the sloping curved wall are curved and protrude towards the center of the guide hole 201. The installation of the heating element 1 inside the bracket 2 facilitates the assembly of the heating element 1 in the heating non-combustible device. The bracket 2 can connect the heating element 1 to the housing 5 of the heating non-combustible device. The guide hole 201 of the bracket 2 has a guide slope 202, which facilitates the smooth insertion of the aerosol matrix 4 into the receiving cavity 101. During the guiding process, because the guide hole 201 has a sloping curved wall, it can pre-compress the aerosol matrix 4, thus guiding the deformation of the aerosol matrix 4. In this embodiment, the inclined curved wall of the guide hole 201 can correspond one-to-one with the curved wall 103 of the receiving cavity 101. In some embodiments, the guide hole 201 on the bracket 2 may not be provided with an inclined curved wall. For example, the guide hole 201 may also be a square conical hole, and each surface of the square conical hole is a plane.

[0043] In one embodiment, the diameter of the inscribed circle of the cross-sectional profile of the guide hole 201 at the end furthest from the insertion port 102 is a first diameter, and the diameter of the inscribed circle of the cross-sectional profile of the guide hole 201 at the end closest to the insertion port 102 is a second diameter. The first diameter is larger than the second diameter, and the second diameter is larger than or equal to the diameter of the inscribed circle a of the cross-sectional profile of the receiving cavity 101. The first diameter being larger than the second diameter allows the formation of a guiding inclined surface 202. In some embodiments, to facilitate the insertion of the aerosol matrix 4, the first diameter can be larger than the outer diameter of the aerosol matrix 4 when it is not compressed. The second diameter being larger than or equal to the diameter of the inscribed circle of the cross-sectional profile of the receiving cavity 101 allows the aerosol matrix 4 to be smoothly inserted into the receiving cavity 101 through the guidance of the guide hole 201. In some embodiments, the second diameter can be set to be equal to or approximately equal to the diameter of the inscribed circle of the cross-sectional profile of the receiving cavity 101. When the cross-sectional profile of the receiving cavity 101 is polygonal, such as... Figure 6 As shown, the inscribed circle a of the cross-sectional profile of the cavity 101 is a circle that is tangent to all sides of the polygon.

[0044] In the heating assembly provided in the above embodiments, the cavity wall of the receiving cavity 101 has a curved wall 103 for compressing the aerosol matrix 4. The cross-sectional profile of the receiving cavity 101 and the portion corresponding to the curved wall 103 are curved and protrude towards the center of the receiving cavity 101. When the aerosol matrix 4 is inserted, the curved wall 103 of the receiving cavity 101 compresses the aerosol matrix 4, causing the aerosol matrix 4 to deform. The deformed aerosol matrix 4 has a portion that stably fits against the cavity wall of the receiving cavity 101, which helps to improve the poor contact between the aerosol matrix 4 and the heating assembly, improves the heat conduction efficiency between the aerosol matrix 4 and the heating assembly, and helps to shorten the preheating time of the aerosol matrix 4.

[0045] Please see Figure 7 , Figure 8 This application embodiment also provides a heating non-combustible device, including a housing 5, a power supply component 7, and a heating component as described above. The heating component and the power supply component 7 are both disposed inside the housing 5, and the heating component and the power supply component 7 are electrically connected.

[0046] It is understood that the heating component in this embodiment is the same as that in the above embodiments, and will not be described in detail here. In this embodiment, the power supply component 7 may include, but is not limited to, a battery and a circuit board. The electrical connection between the power supply component 7 and the heating component can be that the circuit board of the power supply component 7 is electrically connected to the coil or heating wire of the heating component. In this embodiment, the housing 5 may have a hole structure corresponding to the insertion port 102 for the aerosol matrix 4 to be inserted into the receiving cavity 101. In this embodiment, an inner support 6 may be provided inside the housing 5, and the heating component can be fixedly connected to the housing 5 and the inner support 6 through the support 2 included therein.

[0047] In one embodiment, the cross-sectional profile of the receiving cavity 101 is polygonal, with each side of the polygon having a curve protruding towards the center of the receiving cavity 101. The receiving cavity 101 as a whole is polygonal prism, with each side of the polygon having a curve protruding towards the center of the receiving cavity 101, that is, each prism face of the prism-shaped receiving cavity 101 has a curved wall 103. This structure of the receiving cavity 101 facilitates stable contact between the cavity wall of the receiving cavity 101 and the aerosol matrix 4, and the polygon has a good compression effect on the aerosol matrix 4, which helps to reduce the distance between the cavity wall of the receiving cavity 101 and the center of the aerosol matrix 4, and shortens the preheating time of the aerosol matrix 4. In some embodiments, the cross-sectional profile of the receiving cavity 101 can be triangular, rectangular, pentagonal, etc. When it is triangular, it can be an equilateral triangle; when it is rectangular, it can be a square; and when it is pentagonal, it can be a regular pentagon.

[0048] In one implementation, such as Figures 3-6 As shown, the cross-sectional profile of the receiving cavity 101 is rectangular, and the two opposite sides of the rectangle combine to form a hyperbola. The hyperbola shape has symmetry, which is beneficial for uniform heating of the aerosol matrix 4. In some embodiments, in order to further ensure that the aerosol matrix 4 can be heated uniformly, the hyperbola formed by one pair of opposite sides of the rectangle can be the same as or approximately the same as the hyperbola formed by the other pair of opposite sides.

[0049] In the heated non-combustible device provided in the above embodiments, the cavity wall of the receiving cavity 101 has a curved wall 103 for compressing the aerosol matrix 4. The cross-sectional profile of the receiving cavity 101 and the portion corresponding to the curved wall 103 are curved and protrude towards the center of the receiving cavity 101. When the aerosol matrix 4 is inserted, the curved wall 103 of the receiving cavity 101 compresses the aerosol matrix 4, causing the aerosol matrix 4 to deform. The deformed aerosol matrix 4 has a portion that stably fits against the cavity wall of the receiving cavity 101, which helps to improve the poor contact between the aerosol matrix 4 and the heating component, improves the heat conduction efficiency between the aerosol matrix 4 and the heating component, and helps to shorten the preheating time of the aerosol matrix 4.

[0050] Please see Figure 9 This application also provides a heating non-combustible system, including a rod-shaped aerosol matrix 4 and a heating non-combustible device as described above. The aerosol matrix 4 is used to be inserted into the receiving cavity 101 through the insertion port 102.

[0051] It is understood that the heating non-combustion device in this embodiment is the same as that in the above embodiments, and will not be described again here. In this embodiment, the rod-shaped aerosol matrix 4 can be, but is not limited to, a cigarette. When not in use (not compressed), the aerosol matrix 4 can be cylindrical. The aerosol matrix 4 can be inserted into the receiving cavity 101 only when in use, and can be left uninserted in the receiving cavity 101 when not in use.

[0052] In one embodiment, such as Figure 4 , Figure 6 As shown, the diameter of the inscribed circle a of the cross-sectional profile of the receiving cavity 101 is smaller than the outer diameter of the aerosol matrix 4 when it is not compressed. When the aerosol matrix 4 is inserted into the receiving cavity 101, the curved wall 103 of the receiving cavity 101 compresses the aerosol matrix 4, causing it to deform towards the contour shape of the receiving cavity 101. In some embodiments, the diameter of the inscribed circle a of the cross-sectional profile of the receiving cavity 101 may be 0.5 mm to 1.5 mm smaller than the outer diameter of the aerosol matrix 4 when it is not compressed.

[0053] In the heated non-combustible system provided in the above embodiments, the cavity wall of the receiving cavity 101 has a curved wall 103 for compressing the aerosol matrix 4. The cross-sectional profile of the receiving cavity 101 and the portion corresponding to the curved wall 103 are curved and protrude towards the center of the receiving cavity 101. When the aerosol matrix 4 is inserted, the curved wall 103 of the receiving cavity 101 compresses the aerosol matrix 4, causing the aerosol matrix 4 to deform. The deformed aerosol matrix 4 has a portion that stably fits against the cavity wall of the receiving cavity 101, which helps to improve the poor contact between the aerosol matrix 4 and the heating component, improves the heat conduction efficiency between the aerosol matrix 4 and the heating component, and helps to shorten the preheating time of the aerosol matrix 4.

[0054] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
