For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] See also Figures 1 to 6 , an embodiment of the present application provides an aerosol generating medium 1.

[0038] An embodiment of the present application provides an aerosol generating device, comprising a laser heating component and the aerosol generating medium 1 described in any embodiment of the present application, wherein the laser heating component is used to perform laser heating and atomization on the aerosol generating medium 1, and the aerosol generating device has a containing cavity, and the aerosol generating medium 1 is contained in the containing cavity.

[0039] Of course, the aerosol generating medium 1 can also be used in an aerosol generating device that is heated by other heating methods, such as resistance heating, electromagnetic heating, infrared heating, microwave heating, etc. This application uses laser heating as an example for illustrative explanation.

[0040] The aerosol generating device is used to atomize the aerosol generating substrate to generate an aerosol for the user to use. The aerosol generating substrate includes but is not limited to medicines, nicotine-containing materials or nicotine-free materials, etc. The aerosol generating substrate can be a solid material with plants as the main raw material, such as tobacco, and added with corresponding aerosol formers and aroma materials.

[0041] The aerosol-generating medium 1 refers to a medium capable of generating aerosol, and the aerosol-generating medium 1 may contain an aerosol-generating substrate.

[0042] The aerosol generating medium 1 is accommodated in the accommodating chamber, which provides installation space and protection for the aerosol generating medium 1, reduces the probability of damage to the aerosol generating medium 1, and the heat generated by the aerosol generating medium 1 will not be directly transferred to the user, thereby increasing the working reliability of the aerosol generating device.

[0043] It can be understood that the cross-sectional shape of the aerosol generating medium 1 is not limited. In some examples, the cross-sectional shape of the aerosol generating medium 1 is roughly circular, that is, the aerosol generating medium 1 as a whole is roughly cylindrical; in other examples, the cross-sectional shape of the aerosol generating medium 1 is roughly rectangular, that is, the aerosol generating medium 1 as a whole is roughly rectangular, etc.

[0044] The aerosol generating medium 1 can be a replaceable product, that is, the aerosol generating medium 1 can be detachably accommodated in the containing cavity. When the aerosol generating matrix contained in the aerosol generating medium is atomized, the used aerosol generating medium 1 can be taken out from the containing cavity and replaced with an unused aerosol generating medium 1.

[0045] The aerosol generating medium 1 includes a medium peripheral wall 10 for generating aerosol, that is, the surface or interior of the medium peripheral wall 10 contains an aerosol generating matrix. Under the action of the laser heating component, the aerosol generating matrix on the surface or interior of the medium peripheral wall 10 is heated and atomized to generate aerosol for use by users.

[0046] See also Figure 1 and Figure 2 The medium peripheral wall 10 encloses a hollow space 1a. After the aerosol-generating matrix on the surface or inside of the medium peripheral wall 10 is heated and atomized to produce aerosol, the aerosol can be released from the hollow space 1a and then used by the user under the action of suction negative pressure.

[0047] See also Figure 2 The thickness T of the medium peripheral wall 10 is 0.1 mm to 0.4 mm, that is, the thickness T of the medium peripheral wall 10 is 0.1 mm to 0.4 mm, for example, 0.1 mm, 0.12 mm, 0.15 mm, 0.2 mm, 0.23 mm, 0.26 mm, 0.29 mm, 0.31 mm, 0.35 mm, 0.38 mm, 0.4 mm, etc. In this way, the thickness of the medium peripheral wall 10 is relatively thin, and when the medium peripheral wall 10 is heated, the surface and the inside of the medium peripheral wall 10 can be fully heated, thereby generating aerosol.

[0048] It should be noted that the greater the thickness of the aerosol generating medium, the greater the structural strength of the aerosol generating medium and the stronger the installation stability. However, when heated and atomized, the temperature inside the medium wall and the temperature on the surface are too different to maintain the atomization consistency. The medium wall cannot be fully heated, so that the aerosol generating matrix contained in the medium wall cannot be fully utilized, affecting the generation of aerosol. In addition, the aerosol generated after atomization does not have enough release space, which affects the discharge of the aerosol and thus affects the user experience. The smaller the thickness of the aerosol generating medium, the closer the heating temperature inside the medium wall and the heating temperature on the surface are when heated and atomized, and the atomization consistency is high, but the structural stability of the aerosol generating medium will be worse, and it will be prone to deformation, which is not conducive to the structural stability of the aerosol generating device.

[0049] Therefore, in the aerosol generating medium 1 provided in the embodiment of the present application, the medium peripheral wall 10 encloses a hollow space 1a, which can, on the one hand, reduce the weight of the aerosol generating medium 1 and reduce the thickness of the aerosol generating medium 1, so as to facilitate heat atomization. On the other hand, the aerosol generating matrix on the surface or inside of the medium peripheral wall 10 can be directly released from the hollow space 1a after being heated and atomized to generate aerosol, so as to be used by the user. The aerosol has sufficient release space, which improves the utilization rate of the aerosol. The thickness size arrangement of the medium peripheral wall 10 ensures that the aerosol generating medium 1 can ensure its own structural stability while the surface and the inside of the medium peripheral wall 10 can be fully heated when heated, so as to facilitate the rapid generation of aerosol, and the aerosol generating matrix on the surface or inside of the medium peripheral wall 10 can be fully utilized, and the aerosol waiting time is short. The structure of the aerosol generating medium 1 is simple, and it is easy to manufacture and install, so that the user experience is better.

[0050] In some preferred embodiments, the thickness of the medium peripheral wall 10 is 0.18 mm to 0.28 mm. For example, 0.18 mm, 0.19 mm, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, etc. In this embodiment, the thickness of the medium peripheral wall 10 is more reasonable, and the thickness of the medium peripheral wall 10 is not too large or too small. While meeting the structural strength of the aerosol generating medium 1, the medium peripheral wall 10 can be fully heated when heated and atomized, and the aerosol generation speed is fast. In addition, the airway hole 10a can also have enough space for aerosol release, thereby increasing the atomization efficiency.

[0051] For some examples, see Figures 3 to 6 The aerosol generating medium 1 includes an inner frame 11, which is arranged in the medium peripheral wall 10 and divides the hollow space 1a into a plurality of airway holes 10a.

[0052] When the aerosol generating matrix on the surface or inside of the medium peripheral wall 10 is heated and atomized to generate aerosol, the aerosol can be released from the airway hole 10a. After the aerosol enters the airway hole 10a, it can move in the airway hole 10a. When the user inhales, negative pressure is generated. Under the action of negative pressure, the aerosol flows out from the airway hole 10a and is used by the user. In addition, the inner frame 11 can also provide certain structural support for the medium peripheral wall 10, thereby increasing the structural stability of the aerosol generating medium 1.

[0053] It should be noted that the inner wall of the airway hole 10a is relatively smooth, that is, there are no corners or protrusions in the airway hole 10a. The aerosol generated after atomization can flow out of the airway hole 10a faster under the action of the negative pressure of suction, thereby reducing the probability of aerosol depositing at corners or protrusions to produce condensation that affects the user's experience and improving the reliability of atomization.

[0054] It is understandable that the airway hole 10a penetrates at least one end of the aerosol generating medium 1 , and may be one end of the aerosol generating medium 1 or both ends of the aerosol generating medium 1 . In some examples, the airway hole 10a penetrates at least one end of the aerosol generating medium 1 along the axial direction, that is, the airway hole 10a penetrates one end or both ends of the aerosol generating medium 1 along the axial direction. When the airway hole 10a penetrates one end of the aerosol generating medium 1 along the axial direction, the airway hole 10a is formed as a blind hole with one end open and the other end closed. The aerosol generated by the aerosol generating matrix on the surface or inside of the medium peripheral wall 10 after atomization can flow out from the open end under the action of the suction negative pressure for user use; when the airway hole 10a penetrates both ends of the aerosol generating medium 1 along the axial direction, the airway hole 10a is formed as a through hole with both ends open. The aerosol generated by the aerosol generating matrix on the surface or inside of the medium peripheral wall 10 after atomization can flow out from both ends under the action of the suction negative pressure for user use. In this way, the flow rate of the aerosol is faster, and there is enough aerosol for users to use per unit time.

[0055] It should be noted that the multiple airway holes 10a can be two, three or more than three airway holes 10a, and the shape of the airway holes 10a is not limited, and can be any other shape such as fan-shaped, rectangular, elliptical, etc., which is not limited here.

[0056] In some embodiments, the thickness of the medium peripheral wall 10 is set to be uniform.

[0057] In this way, when heated and atomized, the aerosol generating matrix on the surface or inside of the medium peripheral wall 10 can be heated evenly, thereby improving the consistency of atomization and reducing the probability that the aerosol generating matrix is ​​not fully heated and atomized or is overheated to produce adverse substances due to uneven thickness of the medium peripheral wall 10, thereby affecting the user's usage experience. This improves the working reliability of the aerosol generating device.

[0058] The cross-sectional shape of the medium peripheral wall 10 is not limited, and can be any other shape such as a circular ring, a rectangle, etc. In some embodiments, please refer to Figures 1 to 4 The cross section of the medium peripheral wall 10 is annular, so that the structural requirements for the aerosol generating medium 1 can be reduced, the manufacturing difficulty of the medium peripheral wall 10 can be reduced, and thus the overall assembly difficulty of the aerosol generating device can be reduced.

[0059] The specific structure of the inner frame 11 is not limited.

[0060] For some examples, see Figures 3 to 6 The inner frame 11 includes a plurality of brackets 111, the first ends 111a of the plurality of brackets 111 are directly or indirectly connected to each other, the second ends 111b of the plurality of brackets 111 are spaced apart and connected to the inner wall of the medium peripheral wall 10, and the area between two adjacent brackets 111 and the inner wall of the medium peripheral wall 10 defines an airway hole 10a.

[0061] The airway hole 10a is defined by the cooperation between the bracket 111 and the medium peripheral wall 10. While the bracket 111 provides a certain support for the medium peripheral wall 10, it can also make the structure of the aerosol generating medium 1 simpler. Multiple brackets 111 can be evenly arranged inside the medium peripheral wall 10, so that the area of ​​the airway hole 10a defined by any two adjacent brackets 111 and the inner wall of the medium peripheral wall 10 is the same. In this way, when the aerosol generated when the medium peripheral wall 10 is atomized is released toward different airway holes 10a, there will be uniform and sufficient release space.

[0062] It can be understood that the multiple brackets 111 can be two, three or more than three brackets 111.

[0063] It can be understood that the first ends 111a of the multiple supports 111 are directly or indirectly connected to each other. In some embodiments, the first ends 111a of the multiple supports 111 are directly connected to each other, that is, the first ends 111a of the multiple supports 111 are gathered together, so that the area of ​​the airway hole 10a defined by the area between two adjacent supports 111 and the inner wall of the medium peripheral wall 10 is also larger, which is convenient for the release of aerosol. In other embodiments, the first ends 111a of the multiple supports 111 are indirectly connected to each other, that is, the first ends 111a of the multiple supports 111 are connected to each other through other structures, so that the overall stability of the aerosol generating medium 1 is better.

[0064] For some examples, see Figures 3 to 6 The inner frame 11 includes an inner tube 112 , which is hollow and defines at least one airway hole 10 a , and a plurality of brackets 111 are radially distributed around the inner tube 112 .

[0065] In this embodiment, the first ends 111 a of the plurality of brackets 111 are connected to each other via the inner tube 112 , so that the inner tube 112 can provide support for the plurality of brackets 111 , thereby increasing the structural stability of the aerosol generating medium 1 .

[0066] It can be understood that the multiple supports 111 are radially distributed around the inner cylinder 112, that is, the inner cylinder 112 is arranged close to the center of the aerosol generating medium 1. The radial distribution means that the multiple supports 111 are arranged circumferentially around the inner cylinder 112. The supports 111 can extend in a straight line or in a curve, and there is no limitation here.

[0067] The inner cylinder 112 is hollow, which, on the one hand, can reduce the overall weight of the aerosol generating medium 1. While ensuring structural stability, the aerosol generating medium 1 can be lightweight, thereby increasing the user experience. On the other hand, the inner cylinder 112 is located close to the center of the aerosol generating medium 1, which is convenient for installation with the aerosol generating device, thereby increasing installation stability, and does not affect the release of aerosol from the medium peripheral wall 10 toward the corresponding airway hole 10a. On the other hand, the inner cylinder 112 may also include an aerosol generating matrix, so that the inner cylinder 112 can also release aerosol toward the surrounding airway holes 10a under the action of the laser heating component, thereby increasing the content of the aerosol and the atomization efficiency.

[0068] The cross-sectional shape of the inner cylinder 112 is not limited, and can be circular, rectangular, polygonal or any other shape, which is not limited here.

[0069] It should be noted that the inner tube 112 defines at least one airway hole 10 a means that the inner tube 112 may define one airway hole 10 a or may define two or more airway holes 10 a .

[0070] It is understandable that in some embodiments, the aerosol generating medium 1 may only have the medium peripheral wall 10 containing the aerosol generating matrix, that is, the aerosol generating medium 1 may only have the medium peripheral wall 10 atomized by heat to generate aerosol, and the inner frame 11 does not contain the aerosol generating matrix and does not generate aerosol; in another embodiment, the medium peripheral wall 10 and the inner frame 11 both contain the aerosol generating matrix and can be atomized by heat. The first laser emission source is arranged outside the medium peripheral wall 10 and is only used to emit laser to the medium peripheral wall 10, so that the aerosol generating matrix on the surface or inside of the medium peripheral wall 10 is atomized to generate aerosol, and a heating component may be arranged in the airway hole 10a to heat and atomize the inner frame 11.

[0071] The aerosol generating medium 1 is heated in any manner.

[0072] In some examples, the laser heating assembly includes a first laser emission source, which is disposed outside the medium peripheral wall 10 and is used to emit laser light toward the medium peripheral wall 10 .

[0073] That is to say, the medium peripheral wall 10 receives the laser emitted by the first laser emission source. When the laser is irradiated to the medium peripheral wall 10 (or irradiated to the light-absorbing layer on the medium peripheral wall 10), the medium peripheral wall 10 will be heated and heated until the atomization temperature is reached. The aerosol generating matrix on the surface or inside of the medium peripheral wall 10 is atomized at the atomization temperature, thereby generating an aerosol for users to use.

[0074] In this embodiment, laser atomization is adopted, and the laser heating efficiency is high and the temperature rises quickly. The aerosol generating matrix on the surface or inside of the aerosol generating medium 1 can be quickly heated and atomized to generate an aerosol. The atomization waiting time is short, and there is no need to preheat the aerosol generating medium 1. The atomization efficiency is high and the structure of the aerosol generating device is simpler, and the user experience is good. In addition, the first laser emission source heats the medium peripheral wall 10 by non-contact heating atomization, and there is no problem of the medium adhering to the surface of the first laser emission source after carbonization. The performance stability of the first laser emission source and the aerosol generating device can be maintained. At the same time, the probability of precipitation of heavy metals and other harmful substances due to the use of heating wires or heating nets to heat the aerosol generating medium 1 can be reduced, thereby improving the stability and safety of the heating atomization of the aerosol generating device.

[0075] It can be understood that the first laser emission source is arranged on the outside of the medium peripheral wall 10, and the size of the laser heating energy can be adjusted by adjusting the distance between the first laser emission source and the medium peripheral wall 10, so as to facilitate real-time adjustment of the heating temperature of the aerosol generating medium 1, improve the accuracy of the heating temperature of the aerosol generating medium 1, maintain the atomization consistency of the aerosol generating medium 1, and enhance the user experience.

[0076] In some other embodiments, the laser heating assembly includes a second laser emission source, which is disposed in at least one airway hole 10a and is used to emit laser light toward an inner wall of the airway hole 10a.

[0077] That is to say, the first laser emission source and the second laser emission source can work together to heat and atomize the aerosol generating medium 1. The medium peripheral wall 10 and the inner frame 11 both contain an aerosol generating matrix, and both can be heated and atomized. In this way, more aerosol is generated by atomization at the same time, and the aerosol generated by atomization can be released in the airway hole 10a and discharged for use by the user, and the atomization efficiency is high. Of course, in some embodiments, the first laser emission source can be used instead of the second laser emission source to heat the aerosol generating matrix.

[0078] When the second laser emission source is arranged in the airway hole 10a defined by the inner cylinder 112, the laser emitted by the second laser emission source irradiates the inner wall of the inner cylinder 112, and the aerosol generated by atomization can be released toward the airway hole 10a on the peripheral side, so that the release of the aerosol is more uniform and will not affect the peripheral wall 10 of the medium.

[0079] In some embodiments, the aerosol generating device includes a rotating component, and the aerosol generating medium 1 can rotate driven by the rotating component.

[0080] That is to say, when the aerosol generating medium 1 is used, it can be rotated under the drive of the rotating assembly, so that each time a part of the medium peripheral wall 10 receives the laser emitted by the first laser emission source (or the second laser emission source) to heat and atomize to generate aerosol, and release it into the corresponding airway hole 10a, which can be one or more corresponding airway holes 10a, while the other part of the medium peripheral wall 10 is not heated and does not generate aerosol. After a part of the medium peripheral wall 10 is heated and atomized, the rotating assembly drives the aerosol generating medium 1 to rotate, so that the other part of the medium peripheral wall 10 receives the laser emitted by the first laser emission source (or the second laser emission source), thereby generating aerosol. In this way, when the irradiation range of the first laser emission source (or the second laser emission source) is certain, the medium peripheral wall 10 can also be fully heated.

[0081] In some embodiments, the outer surface of the dielectric peripheral wall 10 has a light absorbing layer, or the interior of the dielectric peripheral wall 10 has a light absorbing material.

[0082] Specifically, the light-absorbing layer can be black aluminum foil, carbon nanotubes, etc., the light-absorbing material can be natural materials such as tobacco extract containing tobacco melanin, cocoa shell pigment, etc., and the light-absorbing material can also be inorganic materials such as graphene and carbon black, as long as it can absorb light.

[0083] In this embodiment, a light-absorbing layer is provided on the outer surface of the medium peripheral wall 10 or a light-absorbing material is provided inside the medium peripheral wall 10, which can improve the light-absorbing efficiency of the medium peripheral wall 10. The aerosol-generating matrix on the surface or inside of the medium peripheral wall 10 can be heated and atomized more concentratedly and quickly, thereby improving the atomization efficiency.

[0084] Specifically, when the medium peripheral wall 10 receives the laser emitted by the first laser emission source, with the assistance of the light-absorbing layer or the light-absorbing material, the laser emitted by the first laser emission source can be fully received, thereby reducing laser leakage. In this way, the temperature rises faster and the atomization temperature can be reached faster, and the waiting time required for atomization is shorter.

[0085] It can be understood that a light-absorbing layer can also be provided on the inner surface of the medium peripheral wall 10 and the surface of the inner frame 11, and the interior of the inner frame 11 can also have a light-absorbing material. In this way, when a second laser emission source is provided in the airway hole 10a, the laser emitted by the second laser emission source can also be fully received with the assistance of the light-absorbing layer or the light-absorbing material, thereby improving the utilization rate of the laser and increasing the overall atomization speed of the aerosol generating medium 1.

[0086] The molding method of the aerosol generating medium 1 is not limited. In some embodiments, the aerosol generating medium 1 is formed into an integrated structure. That is to say, the medium peripheral wall 10 and the inner frame 11 are integrally molded, and the medium peripheral wall 10 and the inner frame 11 can be integrally molded using the same material. In this way, the molding method is simple, and it is also convenient for the inner frame 11 to provide structural support for the medium peripheral wall 10 during molding, thereby increasing the structural stability of the aerosol generating medium 1; the inner frame 11 and the medium peripheral wall 10 are made of the same material, which can increase the content of the aerosol generating matrix. Both the inner frame 11 and the medium peripheral wall 10 can be heated and atomized under the action of the laser heating component, and release the aerosol toward the airway hole 10a, thereby increasing the atomization efficiency and the amount of aerosol generated, and improving the user experience.

[0087] In other embodiments, the aerosol generating medium 1 is a split structure, that is, the medium peripheral wall 10 and the inner frame 11 are formed as two independent components, which are assembled into the aerosol generating medium 1 after molding. The medium peripheral wall 10 and the inner frame 11 can use the same material or different materials.

[0088] In some embodiments, the aerosol generating medium 1 is an integrally extruded structure.

[0089] Extrusion molding refers to a molding method in which a heated and molten polymer material is forced through a die head under pressure by the extrusion action of a screw or a plunger to form a continuous profile with a constant cross section. In this embodiment, the aerosol generating medium 1 adopts an integrated extrusion molding method, which has high production efficiency, fast molding speed and low production cost.

[0090] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0091] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
