When heating the ACM, external airflow enters through the inner wall of the heating cup within the heating structure. This airflow undergoes heat exchange, becoming hot air, which then heats the ACM. However, due to insufficient heat exchange efficiency within the heating cup, the temperature of the hot airflow cannot be guaranteed, affecting the heating effect on the ACM. Utility Model Content

[0005] The inner wall of the heating cup is provided with a first support body, which forms an airflow channel on the inner wall of the heating cup.

Each layer of the support structure includes multiple circumferentially spaced first support bodies, and the first support bodies in different layers are staggered.

[0012] In one embodiment, the first support is a rhomboid block.

[0013] In one embodiment, the first support is an approximately angular block, with all four sides of the first support recessed toward the center of the first support.

[0028] 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.

[0029] 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).

[0030] Please see Figures 1-5 In one embodiment of this application, a heating assembly is provided. The heating assembly is used in an atomizer as a structure for heating an aerosol forming matrix A. The heating assembly includes a heating cup 10 and a heating element 20.

[0031] Heating cup 10 is used to contain aerosol forming matrix A. Heating element 20 is fixed to heating cup 10 and is used to assist heating cup 10 in heating. Heated heating cup 10 is used to heat aerosol forming matrix A, and the heated aerosol forming matrix A can generate aerosols for users to inhale.

[0032] The inner wall of the heating cup 10 is provided with a first support body 11, which forms an airflow channel on the inner wall of the heating cup 10. The airflow channel is used to allow external airflow to flow to the bottom 10b of the heating cup 10. That is, the airflow channel is connected to both the outside and the bottom 10b inside the heating cup 10.

[0033] The airflow path within the airflow channel is longer than the corresponding length of the inner wall of the heating cup 10 along the axial direction. This effectively increases the contact area between the airflow and the inner wall of the heating cup 10, and prolongs the flow time of the airflow at the inner wall of the heating cup 10. This facilitates sufficient heat exchange before the airflow becomes hot air, allowing it to acquire more heat or increase its temperature. By designing an airflow channel that provides a longer flow path, the heat exchange efficiency of the airflow is effectively improved.

[0034] The heating element 20 can be a resistive heating element or an electromagnetic heating element. When the heating element 20 is a resistive heating element, both the heating element 20 and the heating cup 10 are made of high thermal conductivity materials. For example, the heating element 20 is made of materials with a thermal conductivity >15W / (K*m), such as aluminum nitride, silicon carbide, or alumina, and the heating cup 10 is made of materials with a thermal conductivity >15W / (K*m), such as aluminum alloy, copper, or aluminum nitride. In this case, the heating element 20 can be a sheet-like, mesh-like, or wire-like resistive heating circuit. For example, if the heating element 20 is a sheet-like resistive heating circuit, after the heating element 20 is energized and heats up, the heat is transferred to the heating cup 10. The heating cup 10 then uses the obtained heat to heat the aerosol inside to form matrix A. When the heating element 20 is an electromagnetic heating element, the heating cup 10 is made of magnetic material. For example, the heating element 20 is an electromagnetic coil, and the heating cup 10 is made of materials such as iron, iron-silicon alloy, graphite, and stainless steel. When an alternating current is passed through the electromagnetic coil, an alternating magnetic field is generated. The corresponding heating cup 10 with a certain magnetic permeability will generate an alternating current, thereby generating heat energy to heat the aerosol inside to form matrix A.

[0035] Specifically, in this embodiment, the heating element 20 is a sheet-shaped resistive circuit. The heating element 20 is fixed to the bottom 10b of the heating cup 10. In this way, the heating element 20, as a heat source, is relatively far away from the aerosol forming matrix A inside the heating cup 10. The heat generated by the heating element 20 is transferred to the heating cup 10, which can appropriately reduce the heat at the side wall of the heating cup 10, avoid excessive heat at the side wall of the heating cup 10, and prevent the phenomenon of burning the outer wrapping paper of the aerosol forming matrix A. It can also effectively reduce the amount of impurities released after the outer wrapping paper of the aerosol forming matrix A is heated.

[0036] The first support 11 is strip-shaped or block-shaped, and multiple first support 11s are configured. Multiple airflow channels are formed between the multiple strip-shaped or block-shaped first support 11s, providing sufficient flow space for airflow. The specific number of first support 11s can be 2, 3, 4, 5, etc., which can be selected according to actual needs.

[0037] In some embodiments, the first support 11 is strip-shaped, and multiple first supports 11 are distributed at equal intervals around the inner wall of the heating cup 10. A first airflow groove 12 is formed between adjacent first supports 11 in the circumferential direction, and the space in the first airflow groove 12 is also known as the airflow channel.

[0038] More preferably, a plurality of equally spaced second airflow grooves 13 are formed on the inner wall of the heating cup 10 along the axial direction of the heating cup 10. The first airflow grooves 12 are inclined or parallel to the axis of the heating cup 10, the second airflow grooves 13 are perpendicular or inclined to the first airflow grooves 12, and the second airflow grooves 13 and the first airflow grooves 12 are connected. For example, Figure 2As indicated by the two black arrows, the length direction of the first airflow groove 12 is parallel to the axial direction of the heating cup 10, and the second airflow groove 13 is an annular groove, with its length direction perpendicular to the axial direction of the heating cup 10. Figure 2 As shown, multiple first airflow grooves 12 are formed between multiple vertically distributed first support bodies 11. Based on this, multiple second airflow grooves 13 can be directly opened, which facilitates the production and processing of the heating cup 10.

[0039] When the first airflow channel 12 and the second airflow channel 13 are opened simultaneously, such as Figure 2 As shown, multiple scattered spaces will be generated to serve as airflow channels, that is, the airflow channels are divided into multiple scattered unit channels. Through multiple scattered and connected unit channels, the degree of airflow turbulence at the inner wall of the heating cup 10 can be increased, thereby improving the airflow heat exchange efficiency.

[0040] In some embodiments, the first support 11 is block-shaped and a multi-layer support structure is fixed on the inner wall of the heating cup 10 along the axial direction. Each layer of support structure includes multiple circumferentially spaced first support bodies 11, and the first support bodies 11 in different layers are staggered.

[0041] Specifically, for example Figure 3 As shown, the first support 11 is a rhomboid block. Figure 3 As shown by the black arrow, when external airflow enters the airflow channel at any position of the cup opening 10a and flows to the next layer of support structure, due to the staggered distribution of the adjacent first support bodies 11 and the guiding structure of the rhomboid blocks, the airflow can have at least two flow directions when entering the next layer of support structure, and at least four flow directions when continuing to flow to the next layer of support structure, and so on. All the spaces between the multiple first support bodies 11 on the inner wall of the heating cup 10 are the aforementioned airflow channels. This type of airflow channel allows the air flowing into the heating cup 10 to have multiple paths. By changing the path (or direction) of the airflow, the degree of turbulence in the airflow is increased, thereby improving the airflow heat exchange efficiency.

[0042] Please see Figure 4More preferably, the first support 11 is an approximately prismatic block, with all four sides or sidewalls of the first support 11 recessed towards its center. For example, the sidewalls of the first support 11 are concave arc-shaped sidewalls. When airflow reaches the arc-shaped sidewalls, while the arc-shaped sidewalls can act as guides, the concave structure slows down the airflow, allowing a small vortex to form in the space at the arc-shaped sidewalls of the first support 11. This prolongs the time the airflow spends in the airflow channel, facilitating sufficient heat exchange and increasing the heating effect of the hot airflow on the aerosol forming matrix A. For instance, a hot airflow with higher heat can quickly heat the aerosol forming matrix A, enabling rapid aerosol generation during the preheating stage and reducing user waiting time.

[0043] In other embodiments, the first support 11 can also be a block of other shapes, such as triangle, square, circle or irregular shape. In addition to the regular arrangement method mentioned above, multiple first supports 11 can also be randomly distributed to further increase the degree of turbulence of airflow in the airflow channel. In addition, the gap between adjacent first supports 11 can be adjusted to adjust the degree of turbulence. The specific choice can be made flexibly according to actual needs, and this application does not impose specific limitations.

[0044] In some embodiments, the first support 11 is a spiral support bar distributed along the axial direction of the heating cup 10. For example, Figure 5 As shown, the first support 11 is a spiral-shaped support. The first support 11 is spirally distributed on the inner wall of the heating cup 10 to form multiple support rings. The space between adjacent rings is the airflow channel. Figure 5 The black arrow in the middle indicates the inlet of the airflow channel, allowing external airflow to flow into it. The airflow flowing into the heating cup 10 moves in a spiral trajectory from one end of the cup opening 10a to the other end of the cup bottom 10b, effectively extending the airflow path, increasing the contact area between the airflow and the inner wall of the heating cup 10, and improving the airflow heat exchange efficiency.

[0045] Preferably, an air guiding structure (not shown) is provided on the spiral support bar, which connects the airflow channels on both sides of the spiral support bar. For example, the air guiding structure may have multiple holes or slots on different rings of the spiral first support 11, connecting the airflow channels of adjacent rings. The air guiding structures on adjacent rings are staggered to increase the turbulence of the airflow within the heating cup 10.

[0046] In other embodiments, the spiral-shaped first support 11 can also be configured as multiple pieces, or the strip-shaped first support 11 can also be other shapes, for example, bending multiple segments from one end of the cup mouth 10a of the heating cup 10 to the cup bottom 10b of the cup, forming multiple bent airflow channels (grooves) between adjacent first support 11s. The specific structural design of the first support 11 only needs to be able to extend the flow path of the airflow on the inner wall of the heating cup 10 and increase the contact area between the airflow and the inner wall of the heating cup 10, and will not be exhaustively listed here.

[0047] Please see Figure 2 In this embodiment, a second support 14 is provided inside the bottom 10b of the heating cup 10. The second support 14 is used to contact the end face of the aerosol forming matrix A to form a bottom space, which is connected to the airflow channel. The second support 14 is, for example, a strip, a block, a ring, or other irregularly shaped structure. Specifically, for example... Figure 2 As shown, an annular second support 14 is provided on the inner wall of the bottom 10b of the heating cup 10. The bottom space is formed by the second support 14 and the aerosol matrix A inserted into the heating cup 10.

[0048] Please see Figures 1-6 In another embodiment of this application, an atomizer is provided, including a heating component, a sleeve 30, a top seat 40, and a base 50. The heating component is the same as that in the above embodiment. The heating cup 10 is suspended inside the sleeve 30, and both ends of the sleeve 30 are respectively sleeved to the top seat 40 and the base 50. An insertion channel is formed inside the top seat 40, which is used for the aerosol forming matrix A to pass through and enter the heating cup 10.

[0049] Please see Figure 1 The sleeve 30 is provided with a baffle 31, and the cup opening 10a of the heating cup 10 is provided with a radially outward protruding stop ring 15. The stop ring 15 and the baffle 31 abut against each other to suspend the heating cup 10 inside the sleeve 30. Specifically, the baffle 31 is an annular baffle, and the annular baffle and the stop ring 15 are in surface contact.

[0050] Please see Figure 6The top seat 40 includes a first tube 41, a second tube 42, and a third tube 43 integrally connected in sequence. The end of the first tube 41 furthest from the second tube 42 is inserted into the sleeve 30 and abuts against the stop ring 15. Thus, by the first tube 41 and the baffle 31 abutting against the two ends of the stop ring 15, the heating cup 10 is detachably fixed within the sleeve 30. The second tube 42 is a tapered tube; its radial dimension increases progressively from the first tube 41 side to the third tube 43 side. The tapered shape of the second tube 42 guides the aerosol forming matrix A, facilitating its rapid and accurate insertion into the heating cup 10. The end of the third tube 43 closest to the second tube 42 abuts against the end face of the sleeve 30.

[0051] The sleeve 30, along with the top seats 40 and bases 50 at both ends, can enclose a relatively sealed heating space, preventing heat leakage from the heating components within the sleeve 30 and thus reducing energy loss, thereby improving the thermal efficiency of the heating components. Specifically, the sleeve 30, top seats 40, and bases 50 can all be made of high-temperature resistant, low-thermal-conductivity materials, such as PEEK and PPSU. The materials of the sleeve 30, top seats 40, and bases 50 can be the same or different; this application does not impose specific limitations.

[0052] Please see Figure 1 More preferably, the sleeve 30 also includes a connector 32, which is also a tapered tube. The two ends of the connector 32 are integrally connected to the inner wall of the sleeve 30 and the outer wall of the annular baffle 31, respectively. The tapered tube connector 32 can guide the top seat 40 entering the sleeve 30, which facilitates the quick installation and fixation between the top seat 40 and the sleeve 30.

[0053] Please see Figure 1 and Figure 6 The atomizer also includes a clamping ring 60 and an end cap 70. The clamping ring 60 is tightly fitted inside the third tube 43. The inner wall of the clamping ring 60 has multiple circumferentially spaced clamping portions 61, which are radially inner protrusions. The clamping portions 61 are used to abut against the outer wall of the aerosol forming matrix A to ensure the stability of the aerosol forming matrix A when inserted into the atomizer. Specifically, the clamping ring 60 and its clamping portions 61 are both made of elastic material, such as silicone. The end cap 70 and the end of the third tube 43 away from the second tube 42 are detachably connected, for example, as shown in the image. Figure 1 As shown, the end cap 70 is an annular cap, and multiple spaced protrusions 71 are provided on the outer wall of the end cap 70. Correspondingly, multiple spaced grooves 431 are opened on the end face of the third tube 43, and the protrusions 71 and the grooves 431 are tightly fitted together.

[0054] Please see Figure 6When using the atomizer, the aerosol forming matrix A is inserted into the heating cup 10, and power is supplied to the heating element 20. The heating cup 10 then begins to heat the aerosol forming matrix A. When the user inhales the aerosol forming matrix A, the external airflow enters the airflow channel within the heating cup 10 through the space between the inner wall of the clamping ring 60 and the outer wall of the aerosol forming matrix A via the clamping part 61. The external airflow undergoes sufficient heat exchange within the airflow channel, becoming a hot airflow. This hot airflow flows towards the bottom space of the cup bottom 10b, and then flows into the interior of the aerosol forming matrix A through its end face, thus providing heating. Because the airflows interfere with each other within the airflow channel, the turbulence is increased, and the heat exchange area is also relatively increased, thereby enhancing the heat exchange efficiency of the airflow and increasing the temperature of the hot airflow, facilitating the rapid generation of aerosols after the aerosol forming matrix A is heated. By using the heating component described in the above embodiment, the atomizer's power consumption can be reduced or its thermal utilization rate can be improved by increasing the heat exchange efficiency.

[0055] Please see Figures 1-6 In another embodiment of this application, a heat-not-burn atomizing device is provided, including an atomizer, a housing 80, a battery 90, and a circuit board. The atomizer is the same as in the above embodiment. The atomizer, battery 90, and circuit board are all fixed inside the housing 80. The battery 90 is electrically connected to the heating element 20, and the battery 90 and the heating element 20 are respectively electrically connected to the circuit board. The battery 90 is used to provide electrical energy to the heating element 20, and the circuit board is used to control the working state of the heating element 20. A insertion hole 81 is provided on the top surface of the housing 80. The insertion hole 81, the top seat 40, and the heating cup 10 are coaxially distributed. The insertion hole 81 is used for the aerosol forming matrix A to pass through and enter the atomizer.

[0056] The heated non-combustible atomizing device includes the atomizer containing a heating component in the above embodiments. Therefore, it also has the advantages or beneficial effects of the heating component, which will not be elaborated here.

[0057] 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.
