[0048] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0049] Embodiment 1

[0050] In the first aspect, please refer to Figures 1 to 9As shown, this embodiment provides a heating module for heating an aerosol generating article 100, which has high versatility and a large application range. Exemplarily, the outer shape of the aerosol generating article 100 in this embodiment can be cylindrical or flat cylindrical. The aerosol generating article 100 includes, but is not limited to, a cigarette or other aerosol products. The aerosol generating article 100 includes a filter section (not shown in the figure) and a heating section (not shown in the figure). The heating section includes a smokable material, preferably a tobacco-containing material that releases volatile compounds from the matrix when heated; or it can also be a non-tobacco material that is suitable for electrically heated smoking after heating. In one example, a solid aerosol forming matrix is preferably used, which can include one or more of powder, granule, fragment, thin strip, strip or flake of vanilla leaf, tobacco leaf, homogenized tobacco, expanded tobacco; or the solid aerosol forming matrix can contain additional tobacco or non-tobacco volatile flavor compounds to be released when the matrix is heated.

[0051] The heating module includes a module housing 1, a heating element 2 and a shaping structure 3. Among them, the module housing 1 is provided with an insertion port 11 and a receiving cavity 12 communicating with the insertion port 11. Among them, the insertion port 11 is arranged on one end face of the module housing 1, and the aerosol generating article 100 is removably received in the receiving cavity 12 through the insertion port 11. In some alternative embodiments, the module housing 1 can be used to limit the position of the aerosol generating article 100, so that when the aerosol generating article 100 is located in the receiving cavity 12, it will not move laterally, so as to improve the stability of the aerosol generating article 100.

[0052] The heating element 2 is used to heat the aerosol generating article 100. When the aerosol generating article 100 is an aerosol product, an aerosol will be generated after the aerosol generating article 100 is heated. Specifically, the heating element 2 is arranged in the module housing 1, and the heating element 2 has a heating surface 21. In this embodiment, the heating surface 21 is arranged facing the aerosol generating article 100. After the aerosol generating article 100 extends into the receiving cavity 12, the heat emitted by the heating surface 21 can heat the aerosol generating article 100 to generate an aerosol.

[0053] As Figure 1 shown, the shaping structure 3 is arranged on the cavity wall of the receiving cavity 12 near the insertion port 11 and is used to shape the aerosol generating article 100 so that the outer peripheral wall surface of the aerosol generating article 100 can be shaped into a heated surface (not shown in the figure) that matches the shape of the heating surface 21. Specifically, when the aerosol generating article 100 is inserted into the receiving cavity 12 through the insertion port 11, it passes through the shaping structure 3, so that the shaping structure 3 can contact the outer peripheral wall surface of the aerosol generating article 100, and then partially or completely shape the outer peripheral wall surface, so that the aerosol generating article 100 can be shaped into a heated surface.

[0054] In this embodiment, as Figure 8 shown, the heating surface 21 is in contact with or parallel to the heated surface, so that the heat of the heating surface 21 can be quickly transferred to the heated surface, improving the heating efficiency and heating effect on the aerosol generating article 100. Among them, when the heating surface 21 is in contact with the heated surface, the heating efficiency can be further improved, so that the temperature of the aerosol generating article 100 reaches the required value in a short time. Moreover, when the heating surface 21 is in contact with the heated surface, the aerosol generating article 100 can be limited, reducing the probability of the aerosol generating article 100 moving during the heating process. When the heating surface 21 is parallel to the heated surface, each position of the heated surface is heated more evenly, avoiding the problem of excessive local temperature and having high reliability.

[0055] In the heating module provided in this embodiment, the heating element 2 is arranged in the module housing 1 and has a heating surface 21. The shaping structure 3 is arranged on the cavity wall of the receiving cavity 12 of the module housing 1 near the insertion port 11 and is used to shape the aerosol generating article 100 so that the outer peripheral wall surface of the aerosol generating article 100 can be shaped into a heated surface matching the shape of the heating surface 21. The heating surface 21 is in contact with or parallel to the heated surface to have high heating efficiency and heating effect. Through the shaping of the shaping structure 3, the heating module can be used to heat aerosol generating articles 100 with various shapes while ensuring high heating efficiency and heating effect, having high versatility and a wide application range.

[0056] As a preferred implementation, as Figure 3 shown, the shaping structure 3 includes a guiding inclined surface 311 inclined relative to the cavity wall of the receiving cavity 12 and a shaping surface 321 matching the shape of the heating surface 21. Among them, the guiding inclined surface 311 is used to guide the outer peripheral wall surface of the aerosol generating article 100 to the shaping surface 321, and the shaping surface 321 is used to abut against the outer peripheral wall surface of the aerosol generating article 100 to shape the aerosol generating article 100.

[0057] In this embodiment, by setting the guiding inclined surface 311, the problem that the shaping structure 3 abuts against the end of the aerosol generating article 100 and the aerosol generating article 100 cannot enter the receiving cavity 12 can be prevented, so that the aerosol generating article 100 can smoothly enter the receiving cavity 12, reducing the difficulty of the aerosol generating article 100 entering the receiving cavity 12. It also avoids the problem that the immediate heating element cannot enter the receiving cavity 12 due to the blocking of the shaping structure 3, facilitating use. Moreover, by guiding the outer peripheral wall of the aerosol generating article 100 to the shaping surface 321 through the guiding inclined surface 311, the difficulty of the aerosol generating article 100 contacting the shaping surface 321 is reduced.

[0058] Exemplarily, the shape of the shaping surface 321 matching the shape of the heating surface 21 can be understood as the shape of the shaping surface 321 being the same as the shape of the heating surface 21, so that the shape of the heated surface obtained after being shaped by the shaping surface 321 can be the same as the shape of the heating surface 21, facilitating the fitting or parallelism of the heated surface and the heating surface 21.

[0059] It should be noted that the guiding inclined surface 311 in this embodiment is closer to the insertion port 11 than the shaping surface 321, that is, in the insertion direction of the aerosol-generating article 100 inserted into the receiving cavity 12, the guiding inclined surface 311 and the shaping surface 321 are arranged in sequence.

[0060] In some alternative embodiments, such as Figure 5 shown, the heating surface 21 is a flat surface. In some other alternative embodiments, the heating surface 21 is a curved surface or an arc surface, and this embodiment does not limit this.

[0061] In some alternative embodiments, the guiding inclined surface 311 is docked with the shaping surface 321, that is, the aerosol-generating article 100 directly enters the shaping surface 321 after passing through the guiding inclined surface 311. By setting the guiding inclined surface 311 to be directly docked with the shaping surface 321, the size of the shaping structure 3 in the insertion direction of the aerosol-generating article 100 can be smaller, which is beneficial to the miniaturization of the heating module.

[0062] In some other alternative embodiments, such as Figure 3 shown, the shaping structure 3 further includes an arc transition surface 312. The arc transition surface 312 is connected between the guiding inclined surface 311 and the shaping surface 321. The arc transition surface 312 is used for a smooth transition between the guiding inclined surface 311 and the shaping surface 321, reducing the situation where convex edges appear on the surface of the shaping structure 3 for contacting the aerosol-generating article 100, making the surface of the shaping structure 3 for contacting the aerosol-generating article 100 smoother, thereby reducing the probability of scratching or damaging the outer wall of the to-be-instant-heating part, and having high reliability.

[0063] Exemplarily, the shaping surface 321 is parallel or coplanar with the heating surface 21. Among them, Figure 5 is a schematic diagram of the shaping surface 321 and the heating surface 21 being coplanar. At this time, the shaped heated surface can be attached to the heating surface 21.

[0064] It should be noted that when the shaping surface 321 is parallel to the heating surface 21, the shaping surface 321 is closer to the axis of the receiving cavity 12 than the heating surface 21. If the heating surface 21 is closer to the axis of the receiving cavity 12 than the shaping surface 321, the lateral dimension of the space formed by enclosing the heating surface 21 is smaller than the lateral dimension of the space formed by enclosing the shaping surface 321. At this time, when the cross-sectional dimension of the aerosol-generating article 100 is large, there will be a problem that it cannot enter the space formed by enclosing the heating surface 21. When the cross-sectional dimension of the aerosol-generating article 100 is small, there will be a problem that the shaping surface 321 cannot shape the circumferential outer wall of the surface to be heated. In this embodiment, making the shaping surface 321 closer to the axis of the receiving cavity 12 than the heating surface 21 enables the shaping surface 321 to effectively shape the circumferential outer wall of the aerosol-generating article 100 and smoothly enter the space formed by enclosing the heating surface 21.

[0065] In some alternative embodiments, as Figure 3 shown, one end of the guiding inclined surface 311 facing away from the shaping surface 321 extends to the insertion port 11, so that the aerosol-generating article 100 can contact the guiding inclined surface 311 as soon as it enters the insertion port 11 and is deformed under the action of the guiding inclined surface 311, enabling the shaping structure 3 to be closer to the insertion port 11. And when the axial dimension of the module housing 1 is fixed, the dimension of the shaping structure 3 in the insertion direction can be large and will not affect the dimension of the heating element 2 in the insertion direction, taking into account both the heating effect and the shaping effect.

[0066] Exemplarily, as Figure 4 shown, the shaping structure 3 can be a protrusion provided on the inner wall of the module housing 1, and the shaping structure 3 includes a connected guiding section 31 and a shaping section 32. The guiding section 31 and the shaping section 32 are connected in sequence in the insertion direction of the aerosol-generating article 100. The guiding inclined surface 311 and the arc transition surface 312 are both provided on the guiding section 31, and the shaping surface 321 is provided on the shaping section 32. One end of the guiding section 31 facing away from the shaping section 32 extends to the insertion port 11.

[0067] In some alternative embodiments, a plurality of shaping structures 3 and heating surfaces 21 are provided in one-to-one correspondence. The heated surface shaped by the shaping structure 3 matches the heating surface 21 corresponding to the shaping structure 3. By providing a plurality of shaping structures 3, a plurality of heated surfaces corresponding to the plurality of heating surfaces 21 one by one can be formed, and each heated surface is in contact with or parallel to its corresponding heating surface 21, realizing multi-region heating of the aerosol-generating article 100 and further improving the heating efficiency and heating effect.

[0068] Exemplarily, the plurality of heating surfaces 21 can be the surface of one heating element 2, or the heating module includes a plurality of heating elements 2, and each heating element 2 has a heating surface 21. This embodiment does not make a limitation in this regard. In this embodiment, asFigure 7 As shown, there are two heating elements 2, and the two heating elements 2 are arranged oppositely.

[0069] Of course, it can be understood that there can also be one shaping structure 3. This one shaping structure 3 is annular so as to be able to shape the entire circumferential outer wall of the aerosol generating article 100. For example, after the aerosol generating article 100 passes through the annular shaping structure 3, four planar heating surfaces are formed. There are four heating surfaces 21, and the four heating surfaces 21 heat the four heating surfaces simultaneously.

[0070] Exemplarily, as Figure 5 and Figure 6 shown, the module housing 1 includes a support main body 13 and an end cover member 14 provided at one end in the axial direction of the support main body 13. The insertion port 11 is provided on the end face of the end cover member 14 facing away from the support main body 13. The accommodation cavity 12 includes a first sub-cavity 121 provided in the support main body 13 and a second sub-cavity 122 provided in the end cover member 14, and the first sub-cavity 121 communicates with the second sub-cavity 122. By providing the support main body 13 and the end cover member 14, the manufacturing difficulty of the heating module can be reduced.

[0071] In some alternative embodiments, a sealing ring is provided between the support main body 13 and the end cover member 14 for sealing the gap between the support main body 13 and the end cover member 14, so that the accommodation cavity 12 can be relatively sealed.

[0072] In this embodiment, the heating element 2 is provided on the support main body 13 to be supported by the support main body 13. The shaping structure 3 is provided on the wall of the second sub-cavity 122 to shape the aerosol generating article 100 before the aerosol generating article 100 is heated by the heating element 2.

[0073] In some alternative embodiments, the shaping structure 3 and the end cover member 14 are an integrally formed structure, that is, the shaping structure 3 and the end cover member 14 can be formed in one manufacturing process. By setting the shaping structure 3 to be integrally formed with the end cover member 14, the integrity of the shaping structure 3 and the end cover member 14 can be improved, and the probability of connection failure between the shaping structure 3 and the end cover member 14 can also be reduced, having relatively high reliability.

[0074] Of course, it can be understood that the shaping structure 3 can also be detachably connected to the end cover member 14 to facilitate the replacement of the shaping structure 3, having relatively high flexibility.

[0075] Optionally, the first sub-chamber 121 has a profiling chamber wall 1211, and the heating surface 21 is coplanar with the profiling chamber wall 1211, so that the heating surface 21 does not protrude relative to the profiling chamber wall 1211. Furthermore, the heating element 2 will not block the aerosol-generating article 100 from entering the first sub-chamber 121 due to abutting against the end face of the aerosol-generating article 100, reducing the difficulty for the aerosol-generating article 100 to extend into the first sub-chamber 121 and improving the convenience of using the heating module.

[0076] Exemplarily, the profiling chamber wall 1211 is used to profile the shape of the aerosol-generating article 100, so that the first sub-chamber 121 can better position the aerosol-generating article 100 in the radial direction of the aerosol-generating article 100 and improve the stability of the aerosol-generating article 100.

[0077] It should be noted that when there are multiple heating surfaces 21, there are multiple profiling chamber walls 1211 corresponding to the heating surfaces 21, and each heating surface 21 is coplanar with its corresponding profiling chamber wall 1211.

[0078] In this embodiment, the support body 13 is an integrally formed structure, that is, the support body 13 is a one-piece structure, which is convenient for the assembly of the heating module and reduces the assembly steps. And, as Figure 1 shown, the heating module further includes a connecting member 4, and the connecting member 4 is connected to the support body 13.

[0079] Specifically, as Figure 6 and Figure 7 shown, the connecting member 4 is provided with two clamping portions 41, and two opposite outer side surfaces of the support body 13 are both provided with clamping grooves 131. The two clamping portions 41 are respectively clamped in the clamping grooves 131 to realize the clamping of the connecting member 4 and the support body 13, facilitating the connection and disassembly of the connecting member 4 and the support body 13.

[0080] Please continue to refer to Figure 6 , the support body 13 is provided with a hollow 132 communicating with the first sub-chamber 121. The heating element 2 is arranged in the hollow 132. In some alternative embodiments, the heating element 2 can be limited in the hollow 132 and abuts against the support body 13.

[0081] Please refer to Figure 7 and Figure 10, the heating module further includes a temperature measuring element 7 for detecting the temperature of the heating element 2. Exemplarily, the temperature measuring element 7 may include, but is not limited to, a thermocouple. In this embodiment, the temperature measuring element 7 is clamped between the surface of the heating element 2 facing away from the first sub-cavity 121 and the connecting member 4 to improve the accuracy of the measured temperature of the heating element 2. In some alternative embodiments, the temperature measuring element 7 is disposed on the connecting member 4 such that the connecting member 4 is used to hold the temperature measuring element 7 on the heating element 2. For example, the connecting member 4 is provided with a groove in which the temperature measuring element 7 can be positioned to prevent the temperature measuring element 7 from moving relative to the heating element 2. In some other alternative embodiments, the temperature measuring element 7 is clamped between the heating element 2 and the connecting member 4 to fix its position relative to the heating element 2.

[0082] In some alternative embodiments, a portion of the surface of the heating element 2 facing the first sub-cavity 121 abuts against the support body 13. When the connecting member 4 is snap-connected to the support body 13, the heating element 2 can be pressed against the support body 13 to improve the stability of the heating element 2. At the same time, the connecting member 4 also presses the temperature measuring element 7 against the heating element 2 to make the temperature measuring element 7 in close contact with the heating element 2.

[0083] Exemplarily, as Figure 10 shown, the heating element 2 in this embodiment includes a substrate (not shown in the figure). An infrared coating 22 is formed on the surface of the substrate facing the first sub-cavity 121. The infrared coating 22 is used to receive the electric power of the power supply to generate heat and transfer the heat to the aerosol generating article 100 received in the receiving cavity 12 at least by infrared radiation to generate an aerosol. At least a part of the outer surface of the infrared coating 22 and the surface of the substrate facing away from the first sub-cavity 121 are covered with an electrode coating 23 for supplying the electric power of the power supply to the infrared coating 22.

[0084] Optionally, the electrode coating 23 covering the infrared coating 22 is electrically connected to the electrode coating 23 on the surface of the substrate facing away from the first sub-cavity 121. The electrode coating 23 on the surface of the substrate facing away from the first sub-cavity 121 is connected to a wire through an electrode tab 24 to form a circuit.

[0085] In a second aspect, this embodiment also provides an aerosol generating device including the heating module in the first aspect. The aerosol generating device provided in this embodiment has high versatility and a wide range of applications.

[0086] Exemplarily, as Figure 4 and Figure 5 shown, the aerosol generating device further includes a housing 10. The heating module is disposed in the housing 10. The housing 10 is provided with a through hole communicating with an insertion port 11. One end of the aerosol generating article 100 passes through the through hole and the insertion port 11 and extends into the receiving cavity 12.

[0087] Exemplarily, the aerosol generating device further includes components such as an electrode, a thermocouple, an inner aerogel, an outer aerogel, a heat insulation tube, and an aerogel outside the tube. For example, the electrode, the thermocouple, and the inner aerogel are all disposed on the support body 13. An upper side cover plate is connected between the support body 13 and the housing 10 to prevent the internal components from loosening. An outer aerogel, a heat insulation tube, an aerogel outside the tube, and a sleeve are sleeved outside the support body 13 to enhance heat dissipation and reduce the risk of overheating.

[0088] In the heating module and the aerosol generating device provided in this embodiment, a shaping structure 3 is provided on the inner wall of the end cap member 14. When the aerosol generating article 100 is inserted into the second sub-cavity 122 of the end cap member 14, it is first clamped by the silica gel claws to maintain its shape, and then the aerosol generating article 100 is shaped into a shape with a heating surface (such as an ellipse) by the shaping structure 3 to adapt to the heating method of the sheet-shaped heating element 2. It can be seen that this heating assembly is applicable to both cylindrical aerosol generating articles 100 and flat aerosol generating articles 100. Moreover, the heating module and the aerosol generating device have low cost, good power consumption, and a mature process for manufacturing the heating sheet, and have good mass production feasibility.

[0089] Embodiment 2

[0090] The difference between this embodiment and Embodiment 1 lies in the specific structure of the support body 13 being different.

[0091] Specifically, as Figure 11 and Figure 12 shown, the support body 13 in this embodiment is a split structure. Moreover, the support body 13 is a split structure, and the support body 13 includes a bottom plate 134, a top plate 133, and two first enclosing plates 135 and two second enclosing plates 136 connected between the bottom plate 134 and the top plate 133. The two first enclosing plates 135 are arranged oppositely, and the two second enclosing plates 136 are arranged oppositely. Exemplarily, clamping grooves (not shown in the figure) are provided on both the bottom plate 134 and the top plate 133, and protrusions (not shown in the figure) are provided at the bottom of the first enclosing plate 135 and the bottom plate 134 of the second enclosing plate 136. The protrusions can be correspondingly snapped into the clamping grooves to achieve the snap connection of the first enclosing plate 135 and the second enclosing plate 136 with the top plate 133 and the snap connection of the first enclosing plate 135 and the second enclosing plate 136 with the bottom plate 134, so that the bottom plate 134, the top plate 133, the two first enclosing plates 135, and the two second enclosing plates 136 cooperate with each other to reach a stable state. Exemplarily, a limiting sleeve 6 is also sleeved outside the two first enclosing plates 135 and the two second enclosing plates 136 to improve the fastening degree of the first enclosing plate 135 and the second enclosing plate 136.

[0092] In this embodiment, the two first enclosing plates 135 and the two second enclosing plates 136 are both used to enclose the first sub-chamber 121. The top plate 133 is provided with a hole structure (not shown in the figure), and the hole structure is used to communicate with the second sub-chamber 122 and the first sub-chamber 121. The heating element 2 is connected to the first enclosing plate 135, that is, the fixing of the heating element 2 is achieved through the first enclosing plate 135. The end cover member 14 in this embodiment is connected to the top plate 133.

[0093] It should be noted that when there is one heating element 2, one heating element 2 is arranged on any one of the first enclosing plates 135. When there are two heating elements 2, the two heating elements 2 are arranged on the two first enclosing plates 135 in a one-to-one correspondence.

[0094] Optionally, as Figure 12 and Figure 13 shown, the heating module further includes a conductive member 5. The first enclosing plate 135 is provided with an installation groove 1351, and the conductive member 5 is arranged in the installation groove 1351 and is electrically connected to the heating element 2. By arranging the conductive member 5 in the installation groove 1351, the probability of the conductive member 5 coming into contact with other electrical appliances (such as thermocouples) on the first enclosing plate 135 and short-circuiting can be reduced, realizing the separation of the conductive member 5 from other electrical appliances, reducing the risk of short-circuit, and improving the use safety. It should be noted that one end of the conductive member 5 can be provided with a hook structure, and the hook structure is hooked on the edge of the first enclosing plate 135 to achieve fixation on the first enclosing plate 135.

[0095] Exemplarily, in this embodiment, one heating element 2 is correspondingly electrically connected to two conductive members 5. At this time, the first enclosing plate 135 is provided with two installation grooves 1351, and the two conductive members 5 are arranged in the two installation grooves 1351 in a one-to-one correspondence.

[0096] In some alternative embodiments, the conductive member 5 in this embodiment can include a spring piece structure, and the spring piece structure elastically abuts against the electrode on the heating element 2 to improve the reliability of the electrical connection.

[0097] Other structures in this embodiment are similar to the corresponding structures in Embodiment 1 and have similar beneficial effects, and will not be elaborated here in this embodiment.

[0098] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
