[0047] See also Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present application provides a heating assembly 10, including: a heating body 1, a fixing part 2 and a heat insulation part 3.

[0048] The heating element 1 is used to heat an aerosol-generating article 200. The aerosol-generating article 200 refers to an article comprising an aerosol-generating substrate that is intended to be heated rather than combusted to release volatile aerosol-generating compounds. When heated, the aerosol-generating substrate releases the volatile aerosol-generating compounds. Compared to aerosols generated by combustion or pyrolytic degradation of the aerosol-generating substrate, the aerosol generated by heating the aerosol-generating substrate may contain fewer known hazardous components. The aerosol-generating article 200 may be disposable or reusable. The aerosol-generating substrate may be a solid aerosol-generating substrate. Alternatively, the aerosol-generating substrate may include both solid and liquid components. The aerosol-generating substrate may include tobacco material and / or non-tobacco material; the tobacco-containing material may contain volatile tobacco flavor compounds that are released from the substrate upon heating.

[0049] The fixing member 2 is connected to the heating body 1 and is used to fix the heating body 1. The fixing member 2 is provided to fix the heating body 1.

[0050] The heat-insulating member 3 is sleeved on at least a portion of the outer periphery of the heating body 1. By sleeved on at least a portion of the outer periphery of the heating body 1, the heat generated by the heating body 1 is gathered and the aerosol generated by the heating body 1 is prevented from being lost.

[0051] The fixing member 2 is provided with a plurality of first connecting portions 21, and the thermal insulation member 3 is provided with a plurality of second connecting portions 31 corresponding to the positions of the first connecting portions 21. The first connecting portions 21 and the corresponding second connecting portions 31 are detachably connected to each other so that the thermal insulation member 3 can be matched or separated from the fixing member 2. By connecting or separating the first connecting portions 21 and the second connecting portions 31, the thermal insulation member 3 can be simply and conveniently assembled to the fixing member 2 through the connection of the first connecting portions 21 and the second connecting portions 31, or the thermal insulation member 3 can be quickly removed from the fixing member 2 by separating the first connecting portions 21 and the second connecting portions 31.

[0052] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 , multiple first connection parts 21 can be arranged along the circumference of the fixing member 2. Multiple second connection parts 31 provided on the fixing member 2 correspond to the positions of the first connection parts 21, and the multiple second connection parts 31 can be arranged around the outer peripheral edge of the fixing member 2. For example, at least a portion of the first connection part 21 can be inserted into the second connection part 31, so that the first connection part 21 and the second connection part 31 can be assembled by rotating the connection, or disassembled by rotating the separation.

[0053] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 , the first connection part 21 and the second connection part 31 may respectively include one and the other of the card slot 21' and the buckle 31'. The detachable connection between the first connection part 21 and the second connection part 31 may be achieved by the snap fit between the card slot 21' and the buckle 31'. Exemplarily, the first connection part 21 may include a plurality of buckles 31', and the second connection part 31 may include a plurality of card slots 21' corresponding to the buckles 31'; or the first connection part 21 may include a plurality of card slots 21', and the second connection part 31 may include a plurality of buckles 31' corresponding to the card slots 21'. Alternatively, the first connection part 21 may be provided with a plurality of buckles 31', and the second connection part 31 may be provided with a plurality of card slots 21' corresponding to the buckles 31'. Alternatively, the first connection part 21 may be provided with a plurality of card slots 21', and the second connection part 31 may be provided with a plurality of buckles 31' corresponding to the card slots 21'.

[0054] In some embodiments, see Figure 1 、 Figure 2 and Figure 3 , multiple buckles 31 ′ can be arranged along the circumference of the fixing member 2 , multiple slots 21 ′ arranged on the fixing member 2 correspond to the positions of the buckles 31 ′, and multiple slots 21 ′ can be arranged around the outer peripheral edge of the fixing member 2 .

[0055] In some embodiments, see Figure 4 and Figure 5 The slot 21' may include a mating position 211 and a disengaging position 212; the buckle 31' is configured to be at least partially inserted into the disengaging position 212 and rotate to the mating position 211 under external actuation. This allows the buckle 31' to be connected to the fixing member 2, and the thermal insulation member 3 to be assembled to the fixing member 2.

[0056] In some embodiments, see Figure 4 、 Figure 5 and Figure 6 When the buckle 31' is located at the matching position 211 of the fixing member 2, the buckle 31' can be rotated to the separation position 212 under external actuation, thereby separating the buckle 31' from the fixing member 2, and then the thermal insulation member 3 can be removed from the fixing member 2.

[0057] In some embodiments, see Figure 7 and Figure 8 The heating element 1 and the fixing element 2 can be integrally formed. The heating element 1 can be positioned perpendicular to the fixing element 2, thereby better ensuring concentricity between the heating element 1 and the fixing element 2. When the thermal insulation element 3 engages with the slot 21' on the fixing element 2 via the buckle 31', the thermal insulation element 3 and the fixing element 2 can also be perpendicularly engaged, thereby also ensuring concentricity between the heating element 1 and the thermal insulation element 3, and the distance from the central axis of the heating element 1 to the inner wall of the thermal insulation element 3 is consistent.

[0058] In some embodiments, see Figure 7 and Figure 9 The heating body 1 and the fixing member 2 can be arranged in a split manner. The heating body 1 and the fixing member 2 can be matched with each other by welding, bonding, plugging, threading or any other suitable means.

[0059] In some embodiments, see Figure 7 and Figure 8 , the heating body 1 can be a central heating body 1; a through hole 32 can be provided at the end of the thermal insulation component 3 close to the fixing component 2, and the heating body 1 can be inserted into the through hole 32, and at least part of the heating body 1 is located inside the thermal insulation component 3. For example, a through hole 32 can be provided at the middle position of one end of the thermal insulation component 3 close to the fixing portion. When the thermal insulation component 3 needs to be assembled to the fixing component 2, the heating element on the fixing component 2 can be passed through the through hole 32 and into the interior of the thermal insulation component 3. When the buckle 31' on the thermal insulation component 3 is inserted into the slot 21' on the fixing component 2 and snapped in, the assembly of the thermal insulation component 3 is completed.

[0060] When the heat-insulating element 3 needs to be removed from the fixing element 2, the heat-insulating element 3 can be rotated so that the buckle 31' on the heat-insulating element 3 moves from the engaging position 211 of the locking groove 21' on the fixing element 2 to the separating position 212, and then the heat-insulating element 3 can be pulled away from the outer periphery of the heating element 1. During the removal, the heating element 1 is pulled out from the through hole 32 of the heat-insulating element 3.

[0061] In some embodiments, see Figure 6 、 Figure 7 and Figure 8 A sealing member 4 may be provided between the heat-insulating member 3 and the fixing member 2. The sealing member 4 can seal the gap between the heat-insulating member 3 and the fixing member 2, thereby preventing heat generated by the heating element 1 from being lost through the gap or aerosol generated by the heating element 1 heating the aerosol-generating article 200 from being lost through the gap.

[0062] In some embodiments, see Figure 6 、 Figure 7 and Figure 8 The sealing member 4 can be arranged on the periphery of the through hole 32, and the plurality of second connecting portions 31 can surround the periphery of the sealing member 4. This can seal the gap between the periphery of the through hole 32 and the fixing member 2, preventing the heat or aerosol inside the thermal insulation member 3 from leaking out.

[0063] In some embodiments, see Figure 5 and Figure 6 The end of the thermal insulation member 3 near the fixing member 2 may be provided with a sealing groove 33, into which the sealing member 4 may be installed. The sealing groove 33 thus allows the sealing member 4 to be positioned and secured, preventing it from falling. It also ensures a tight fit between the fixing member 2 and the thermal insulation member 3, preventing heat or aerosols within the thermal insulation member 3 from escaping. For example, the sealing member 4 may be assembled within the sealing groove 33 using an interference fit.

[0064] In some embodiments, see Figure 10 、 Figure 11 and Figure 12 The aerosol generating device 100 may include a heating assembly 10 and a bracket 5 according to any of the above embodiments; the heating assembly 10 may be fixed to the bracket 5. The bracket 5 may be provided inside the aerosol generating device 100, and the bracket 5 may be provided with a fixing portion for fixing the heating assembly 10. The heating assembly 10 may be fixed to the fixing portion of the bracket 5 by any suitable means, such as threaded connection, welding, plug-in connection, or snap-on connection 31'.

[0065] The aerosol generating device 100 also includes a battery for providing electrical energy to the heating assembly 10. The bracket 5 may also include a slot for securing the battery, which can be installed within the slot using an interference fit. A circuit board may also be provided within the aerosol generating device 100, and the circuit board may extend in the same direction as the battery. The battery is electrically connected to the circuit board and provides electrical energy to it. The circuit board is also electrically connected to the heating assembly 10, allowing the operating state of the heating assembly 10 to be controlled, for example, to control the heating element 1 to start or stop heating.

[0066] The aerosol-generating device 100 may be provided with an insertion port and a heating chamber connected to the insertion port, wherein the heating chamber may be the interior space enclosed by the heat-insulating member 3. For example, the heating body 1 may be a central heating body 1, and the aerosol-generating article 200 may be inserted into the heating chamber through the insertion port. At least a portion of the heating body 1 may be inserted into the interior of the aerosol-generating article 200. Under the control of the circuit board, the heating body 1 may be activated to heat the aerosol-generating substrate within the aerosol-generating article 200 to generate aerosol.

[0067] In some embodiments, see Figure 4 、 Figure 11 、 Figure 12 and Figure 13 The fixing member 2 of the heating assembly 10 may be provided with a first positioning member 22, and the bracket 5 may be provided with a second positioning member 51 corresponding to the position of the first positioning member 22; the first positioning member 22 is connected to the second positioning member 51. The connection between the first positioning member 22 and the second positioning member 51 can fix the heating assembly 10 to the bracket 5.

[0068] In some embodiments, see Figure 4 、 Figure 11 、 Figure 12 and Figure 13 The aerosol generating device 100 may further include a fastener 6. The first positioning member 22 may include a notch 221, and the second positioning member 51 may include a pre-positioning portion 511. The notch 221 may engage with the pre-positioning portion 511 to achieve pre-positioning. The fastener 6 may secure the notch 221 to the second positioning member 51. Pre-positioning may be achieved by first engaging the notch 221 on the first positioning member 22 with the pre-positioning portion 511 on the second positioning member 51. The notch 221 of the first positioning member 22 may then be secured to the second positioning member 51 via the fastener 6. This secures the fixing member 2 of the heating assembly 10 to the bracket 5.

[0069] In some embodiments, the notch portion 221 can be set as a "V-shaped" notch portion 221, a "U-shaped" notch portion 221 or a "C-shaped" notch portion 221, etc. The second positioning member 51 can be set as a fixed column, and the fixed column can be provided with a fixing hole 512 extending along the axial direction of the fixed column. It can be understood that the fixing hole 512 can be formed by the side wall of the fixed column. A pre-positioning portion 511 can be provided on the side wall of the fixed column. Exemplarily, the fixed column includes a fixed end and a free end, and the free end of the side wall of the fixed column can be provided with a recessed portion 513 at intervals, so that the protrusion constructed between the two recessed portions 513 can be a pre-positioning portion 511. The position of the pre-positioning portion 511 corresponds to the position of the notch portion 221 on the first positioning member 22 and the shape is adapted, so that the pre-positioning between the fixing member 2 and the bracket 5 can be achieved through the cooperation of the notch portion 221 and the pre-positioning portion 511.

[0070] Furthermore, after the notch 221 and the pre-positioning portion 511 cooperate to achieve alignment between the fixing member 2 and the bracket 5, the notch 221 of the fixing member is secured to the bracket 5 via the fastener 6. For example, the fastener 6 may be a screw, and the inner wall of the fixing hole 512 within the fixing post may be configured with a threaded structure corresponding to the screw, thereby tightening the notch 221 to the free end of the fixing post via the screw. The width of the screw's nut is greater than the width of the notch 221, allowing the nut to press the notch 221 against the free end of the fixing post. This secures the fixing member 2 to the bracket 5.

[0071] In summary, the interior of the aerosol generating device 100 may be provided with a heating component 10, a bracket 5 and a fastener 6, a fixing column is provided on the bracket 5, and a notch portion 221 is provided on the fixing part 2 of the heating component 10. The notch portion 221 and the pre-positioning portion 511 on the fixing column can realize pre-positioning between the fixing part and the bracket 5, and then the notch portion 221 is tightened to the free end of the fixing column by the fastener 6, so as to realize fixing the fixing part 2 on the bracket 5. The fixing part 2 and the heating body 1 can be an integrally formed part, and the fixing part 2 is fixed, that is, the integrally formed part is fixed. In addition, the fixing part 2 and the heat-insulating part 3 of the heating component 10 can be detachably connected. When the heat-insulating part 3 is assembled to the fixing part 2 by the buckle 31' and the slot 21' on the fixing part 2, the entire heating component 10 can be fixed to the bracket 5. The buckle 31' on the thermal insulation component 3 can be rotated from the separation position 212 of the slot 21' on the fixing component 2 to the engagement position 211, thereby realizing the assembly between the thermal insulation component 3 and the fixing component 2; when the buckle 31' is rotated from the engagement position 211 of the slot 21' to the separation position 212, the thermal insulation component 3 and the fixing component 2 can be disassembled.

[0072] It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
