Modes for Carrying Out the Invention

[0021] Unless there is a contradiction, the technical features in the embodiments of the present application can be combined with each other. The detailed description in the specific embodiments should be understood as explaining the gist of the present application and should not be regarded as an undue limitation to the present application.

[0022] In the description of the embodiments of the present application, the orientation or positional relationship indicated by the terms "inside" and "outside" is based on the orientation or positional relationship shown in the drawings. It is only for facilitating the description of the embodiments of the present application and simplifying the description, and does not indicate or imply that the specified device or element must have a specific orientation and must be configured and operated in a specific orientation. Therefore, it should not be understood as a limitation to the embodiments of the present application.

[0023] Referring to FIGS. 1 to 6, the embodiments of the present application provide an aerosol generating medium 1.

[0024] The embodiments of the present application provide an aerosol generating device, the device comprising a laser heating unit and the aerosol generating medium 1 described in any embodiment of the present application. The laser heating unit is used to perform laser heating atomization on the aerosol generating medium 1. The aerosol generating device comprises a housing cavity, and the aerosol generating medium 1 is housed in the housing cavity.

[0025] Of course, the aerosol generating medium 1 is also applicable to aerosol generating devices that perform heating by other heating methods. For example, heating is performed using heating methods such as resistance heating, electromagnetic heating, infrared heating, microwave heating, etc. The present application will be exemplarily described by taking laser heating as an example.

[0026] The aerosol generating device atomizes the aerosol generating substrate to generate an aerosol and is used for user use. The above aerosol generating substrate includes, but is not limited to, pharmaceuticals, nicotine-containing materials or nicotine-free materials, etc. The aerosol generating substrate may be a solid material mainly made of a plant such as tobacco, with corresponding aerosol forming agents and flavoring materials added.

[0027] Aerosol-generating medium 1 refers to a medium capable of generating aerosols, and aerosol-generating medium 1 may contain an aerosol-generating substrate.

[0028] The aerosol generating medium 1 is housed in a containment cavity, which provides mounting space and protection for the aerosol generating medium 1, reducing the probability of damage to the aerosol generating medium 1, and preventing heat generated by heat absorption by the aerosol generating medium 1 from being directly transferred to the user, thereby improving the operational reliability of the aerosol generating device.

[0029] To make it clear, 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 approximately circular, meaning the entire aerosol-generating medium 1 is approximately cylindrical. In other examples, the cross-sectional shape of the aerosol-generating medium 1 is approximately rectangular, meaning the entire aerosol-generating medium 1 is approximately rectangular prism-shaped.

[0030] The aerosol generating medium 1 may be a replaceable product; that is, the aerosol generating medium 1 may be removably housed in a containment cavity, and after the atomization of the aerosol generating substrate contained in the aerosol generating medium is completed, the used aerosol generating medium 1 can be removed from the containment cavity and replaced with an unused aerosol generating medium 1.

[0031] The aerosol generating medium 1 includes a medium peripheral wall 10 for generating aerosols. That is, the surface or interior of the medium peripheral wall 10 contains an aerosol generating substrate. The laser heating unit causes the aerosol generating substrate on the surface or interior of the medium peripheral wall 10 to be atomized by heat, generating an aerosol which is then made available for use by the user.

[0032] Referring to Figures 1 and 2, the medium peripheral wall 10 encloses a single hollow space 1a. After the aerosol-generating substrate on the surface or inside the medium peripheral wall 10 is atomized by heat absorption to generate an aerosol, the aerosol can be released from this hollow space 1a and subsequently used by the user due to the action of suction negative pressure.

[0033] Referring to 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. Thus, the thickness of the medium peripheral wall 10 is relatively thin, and when the medium peripheral wall 10 receives heat, the surface and interior of the medium peripheral wall 10 can be sufficiently heated, thereby generating an aerosol.

[0034] Furthermore, while a greater thickness of the aerosol-generating medium increases its structural strength and mounting stability, when atomization occurs due to heat absorption, the large temperature difference between the internal and external temperatures of the medium's peripheral wall prevents the maintenance of atomization uniformity. As a result, the peripheral wall of the medium is not sufficiently heated, and the aerosol-generating substrate contained within the peripheral wall cannot be fully utilized, affecting aerosol generation. Moreover, the lack of sufficient release space for the aerosol generated after atomization affects aerosol discharge, impacting the user experience. Conversely, a smaller thickness of the aerosol-generating medium results in a closer temperature difference between the internal temperature of the peripheral wall and the external temperature during atomization due to heat absorption, leading to higher atomization uniformity. However, this also reduces the structural stability of the aerosol-generating medium, making it more susceptible to deformation, which is detrimental to the structural stability of the aerosol generator.

[0035] Therefore, according to the aerosol generating medium 1 provided in the embodiment of the present application, the medium peripheral wall 10 encloses a single hollow space 1a. This, firstly, reduces the weight of the aerosol generating medium 1 and decreases its thickness, facilitating atomization by heat absorption. Secondly, after the aerosol generating substrate on the surface or inside of the medium peripheral wall 10 is atomized by heat absorption to generate an aerosol, it can be directly released from the hollow space 1a, so that the aerosol has sufficient release space for use by the user, improving the utilization rate of the aerosol. Thirdly, by setting the thickness of the medium peripheral wall 10, the aerosol generating medium 1 ensures its structural stability, and when the medium peripheral wall 10 is heated, the surface and interior can be sufficiently heated, facilitating rapid aerosol generation. Furthermore, the aerosol generating substrate on the surface or inside of the medium peripheral wall 10 can be fully utilized, resulting in a shorter atomization waiting time, a simpler structure for the aerosol generating medium 1, easier manufacturing and assembly, and a more positive user experience.

[0036] In some relatively preferred embodiments, the thickness of the medium perimeter 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 perimeter wall 10 is more reasonable, and the thickness of the medium perimeter wall 10 is neither too large nor too small. It satisfies the structural strength of the aerosol-generating medium 1, and when the medium perimeter wall 10 is atomized by heat absorption, it can be sufficiently heated, resulting in a fast aerosol generation rate. Furthermore, the airway holes 10a can also have sufficient space for aerosol release, increasing atomization efficiency.

[0037] In some examples, referring to Figures 3 to 6, the aerosol-generating medium 1 includes an internal frame 11, which is located within the medium's peripheral wall 10 and separates the hollow space 1a into multiple airway openings 10a.

[0038] When the aerosol-generating substrate on the surface or inside the medium peripheral wall 10 is atomized by heat absorption to generate an aerosol, the aerosol can be released from the airway holes 10a. After entering the airway holes 10a, the aerosol can move within the airway holes 10a. When the user inhales, a negative pressure is generated, and the aerosol flows out of the airway holes 10a due to the action of the negative pressure and is used by the user. Furthermore, the internal frame 11 can also play a role in providing some structural support to the medium peripheral wall 10, thereby increasing the structural stability of the aerosol-generating medium 1.

[0039] Furthermore, the inner wall of the airway opening 10a is relatively smooth, meaning there are no corners or protrusions inside the airway opening 10a. The aerosol generated after atomization flows out of the airway opening 10a relatively quickly due to the action of suction negative pressure, reducing the probability of aerosol accumulating in corners or protrusions and forming condensate, which would affect the user's experience and thus improving the reliability of atomization.

[0040] To make it clear, the fact that the airway hole 10a penetrates at least one end of the aerosol-generating medium 1 may mean that the airway hole 10a penetrates one end of the aerosol-generating medium 1, or it may mean that the airway hole 10a penetrates 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 its axial direction, that is, the airway hole 10a penetrates one end or both ends of the aerosol-generating medium 1 along its axial direction. When the airway hole 10a penetrates one end of the aerosol-generating medium 1 along its axial direction, the airway hole 10a forms a blind hole with one end open and the other end closed, and the aerosol generated after atomization of the aerosol-generating substrate on the surface or inside the medium wall 10 can flow out from the open end due to the action of suction negative pressure and be used by the user. When the airway opening 10a penetrates both ends of the aerosol-generating medium 1 along its axial direction, the airway opening 10a forms a through-hole with both ends open. After the aerosol-generating substrate on the surface or inside the medium's peripheral wall 10 is atomized, the generated aerosol can flow out from both ends due to the action of suction negative pressure and be used by the user. In this way, the aerosol flow rate is faster, and enough aerosol for the user to use is supplied within a unit time.

[0041] Furthermore, the multiple airway openings 10a may be two, three, or more than three, and the shape of the airway openings 10a is not limited and may be any other shape such as a fan shape, rectangle, or ellipse, and is not limited here.

[0042] In some embodiments, the thickness of the medium peripheral wall 10 is set to be uniform.

[0043] In this way, when atomized by heat absorption, the aerosol-generating substrate on the surface or inside the medium peripheral wall 10 can receive heat uniformly, improving the uniformity of atomization. This reduces the probability that the aerosol-generating substrate will not be sufficiently heated and atomized due to uneven thickness of the medium peripheral wall 10, or that it will be overheated and produce defective substances, thereby affecting the user experience and improving the operational reliability of the aerosol generator.

[0044] The cross-sectional shape of the medium peripheral wall 10 is not limited and may be any other shape such as annular or rectangular. In some embodiments, as shown in Figures 1 to 4, the cross-section of the medium peripheral wall 10 is annular. In this way, the structural requirements for the aerosol generating medium 1 can be reduced, the difficulty of manufacturing the medium peripheral wall 10 can be lowered, and thereby the overall difficulty of assembling the aerosol generating device can be reduced.

[0045] The specific structure of the internal frame 11 is not limited.

[0046] In some embodiments, referring to Figures 3 to 6, the internal 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 region between two adjacent brackets 111 and the inner wall of the medium peripheral wall 10 defines one airway opening 10a.

[0047] The combination of the bracket 111 and the medium perimeter wall 10 defines the airway opening 10a. The bracket 111 provides a certain support to the medium perimeter wall 10 and simplifies the structure of the aerosol-generating medium 1. Multiple brackets 111 can be uniformly arranged inside the medium perimeter wall 10, and the area of ​​the airway opening 10a defined by any two adjacent brackets 111 and the inner wall of the medium perimeter wall 10 can be made the same. In this way, when the aerosol generated when the medium perimeter wall 10 is atomized is released toward different airway openings 10a, a uniform and sufficient release space is ensured.

[0048] To ensure clarity, the above-mentioned brackets 111 may be two, three, or more than three brackets 111.

[0049] To understand this, the first ends 111a of multiple brackets 111 are directly or indirectly interconnected. In some embodiments, the first ends 111a of multiple brackets 111 are directly interconnected, meaning they converge at one location. In this way, the area of ​​the airway opening 10a defined by the region between two adjacent brackets 111 and the inner wall of the medium peripheral wall 10 is also larger, facilitating aerosol release. In some other embodiments, the first ends 111a of multiple brackets 111 are indirectly interconnected, meaning they are interconnected via other structures. In this way, the overall stability of the aerosol-generating medium 1 is improved.

[0050] In some embodiments, referring to Figures 3 to 6, the internal frame 11 includes an inner cylinder 112, which is hollow and defines at least one airway opening 10a, and a plurality of brackets 111 are distributed radially around the inner cylinder 112.

[0051] In this embodiment, the first ends 111a of the multiple brackets 111 are interconnected via an inner cylinder 112. In this way, the inner cylinder 112 provides support to the multiple brackets 111 and can enhance the structural stability of the aerosol-generating medium 1.

[0052] To make it easier to understand, the multiple brackets 111 are distributed radially around the inner cylinder 112, meaning the inner cylinder 112 is positioned near the center of the aerosol-generating medium 1. The radial distribution mentioned above means that the multiple brackets 111 are arranged in the circumferential direction of the inner cylinder 112, and the brackets 111 may extend in a straight line or in a curved line, and are not limited to these.

[0053] By providing the inner cylinder 112 in a hollow structure, firstly, the overall weight of the aerosol generating medium 1 can be reduced, satisfying structural stability and making the aerosol generating medium 1 lighter, thereby improving the user experience. Secondly, by providing the inner cylinder 112 near the center of the aerosol generating medium 1, installation and combination with the aerosol generating device becomes easier, installation stability is increased, and the peripheral wall 10 of the medium does not affect the release of aerosols toward the corresponding airway holes 10a. Thirdly, the inner cylinder 112 may contain an aerosol generating substrate. In this way, the inner cylinder 112 can also release aerosols toward the surrounding airway holes 10a by the action of the laser heating unit, increasing the aerosol content and atomization efficiency.

[0054] The cross-sectional shape of the inner cylinder 112 is not limited and may be any other shape such as annular, rectangular, or polygonal; it is not limited here.

[0055] Furthermore, the statement that the inner cylinder 112 defines at least one airway opening 10a means that the inner cylinder 112 may define one airway opening 10a, or it may define two or more airway openings 10a.

[0056] To make it clear, in some embodiments, the aerosol-generating medium 1 may contain only the aerosol-generating substrate in the medium perimeter 10, meaning that only the medium perimeter 10 is atomized by heat to generate an aerosol, while the internal frame 11 does not contain the aerosol-generating substrate and does not generate an aerosol. In another embodiment, both the medium perimeter 10 and the internal frame 11 contain the aerosol-generating substrate, and both can be atomized by heat. The first laser emission source is provided outside the medium perimeter 10 and is used to emit a laser only onto the medium perimeter 10, causing the aerosol-generating substrate on the surface or inside of the medium perimeter 10 to be atomized to generate an aerosol, and a heating member can be provided in the airway hole 10a to perform heating atomization on the internal frame 11.

[0057] The heat reception method for the aerosol-generating medium 1 is not limited.

[0058] In some examples, the laser heating unit includes a first laser emission source, which is located outside the medium perimeter wall 10 and is used to emit a laser toward the medium perimeter wall 10.

[0059] In other words, the medium peripheral wall 10 receives the laser emitted by the first laser source, and when the laser is irradiated onto the medium peripheral wall 10 (or onto the absorption layer of the medium peripheral wall 10), the temperature of the medium peripheral wall 10 rises due to heat absorption until it reaches the atomization temperature, and the aerosol-generating substrate on the surface or inside of the medium peripheral wall 10 is atomized at the atomization temperature, thereby generating an aerosol that is made available for use by the user.

[0060] In this embodiment, a laser atomization method is employed, resulting in high laser heating efficiency, rapid temperature rise, and rapid atomization of the aerosol-generating substrate on or inside the aerosol-generating medium 1 by heat absorption, thereby generating aerosols. This results in a short atomization waiting time, no need to preheat the aerosol-generating medium 1, high atomization efficiency, a simpler structure for the aerosol generator, and a good user experience. Furthermore, since the heating method of the medium peripheral wall 10 by the first laser emission source is non-contact heating atomization, there is no problem of the medium adhering to the surface of the first laser emission source after carbonization, thus maintaining the performance stability of the first laser emission source and the aerosol generator. At the same time, heating the aerosol-generating medium 1 using a heating wire or heating net reduces the probability of precipitation of harmful substances such as heavy metals, thereby improving the stability and safety of heating atomization in the aerosol generator.

[0061] To make it easier to understand, the first laser emission source is located outside the medium peripheral wall 10, and by adjusting the distance between the first laser emission source and the medium peripheral wall 10, the magnitude of the laser heating energy can be adjusted, allowing for real-time adjustment of the heating temperature of the aerosol generating medium 1, improving the accuracy of the heating temperature of the aerosol generating medium 1, maintaining the uniformity of atomization of the aerosol generating medium 1, and improving the user experience.

[0062] In some other embodiments, the laser heating unit includes a second laser source, which is located within at least one airway opening 10a and is used to emit a laser toward the inner wall of the airway opening 10a.

[0063] In other words, the first and second laser sources work together to heat and atomize the aerosol-generating medium 1, and both the medium's peripheral wall 10 and the internal frame 11 contain the aerosol-generating substrate, both of which can be atomized by heat absorption. Thus, more aerosols are generated by atomization in the same amount of time, and all of the aerosols generated by atomization are released and discharged into the airway holes 10a for use by the user, resulting in high atomization efficiency. Of course, in some embodiments, the aerosol-generating substrate may be heated using the second laser source without using the first laser source.

[0064] When the second laser source is located within the airway opening 10a defined by the inner cylinder 112, the laser emitted by the second laser source is irradiated onto the inner wall of the inner cylinder 112, and the aerosol generated by atomization can be emitted toward the circumferential airway opening 10a. This results in more uniform aerosol emission without affecting the circumferential wall 10 of the medium.

[0065] In some embodiments, the aerosol generating device includes a rotating unit, and the aerosol generating medium 1 is rotatable by the drive of the rotating unit.

[0066] In other words, when the aerosol-generating medium 1 is used, it can be rotated by the drive of a rotating unit, thereby so that each time, a portion of the medium's peripheral wall 10 is heated and atomized by the laser emitted from the first laser source (or second laser source), generating an aerosol which is then released into the corresponding airway opening 10a, which may be one or more. The other portion of the medium's peripheral wall 10 is not heated and does not generate an aerosol. After the heating and atomization of a portion of the medium's peripheral wall 10 is complete, the rotating unit drives the aerosol-generating medium 1 to rotate so that the other portion of the medium's peripheral wall 10 receives the laser emitted from the first laser source (or second laser source), thereby generating an aerosol. In this way, even if the irradiation range of the first laser source (or second laser source) is constant, the medium's peripheral wall 10 can be sufficiently heated.

[0067] In some embodiments, the outer surface of the medium peripheral wall 10 has an absorbent layer, or the interior of the medium peripheral wall 10 has an absorbent material.

[0068] Specifically, the light-absorbing layer may be black aluminum foil, carbon nanotubes, etc., the light-absorbing material may be a natural material such as tobacco extract containing tobacco melanin or cocoa shell pigment, or an inorganic material such as graphene or carbon black, as long as it can absorb light.

[0069] In this embodiment, by providing an absorbent layer on the outer surface of the medium peripheral wall 10, or by having an absorbent material inside the medium peripheral wall 10, the absorbent efficiency of the medium peripheral wall 10 can be increased, and the aerosol-generating substrate on the surface or inside the medium peripheral wall 10 can be heated and atomized more concentratedly and rapidly, thereby improving the atomization efficiency.

[0070] Specifically, when the medium peripheral wall 10 receives the laser emitted by the first laser source, the absorption layer or absorption material helps to adequately receive the laser emitted by the first laser source, thereby reducing laser leakage. In this way, the temperature rise rate of the medium peripheral wall 10 is faster, it can reach the atomization temperature more quickly, and the waiting time required for atomization is shorter.

[0071] To make it easier to understand, an absorption layer may be provided on the inner surface of the medium peripheral wall 10 and on the surface of the inner frame 11, and an absorption material may also be present inside the inner frame 11. 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 is also sufficiently absorbed with the help of the absorption layer or absorption material, increasing the utilization rate of the laser and increasing the overall atomization rate of the aerosol generating medium 1.

[0072] The molding method for the aerosol-generating medium 1 is not limited. In some embodiments, the aerosol-generating medium 1 is formed as a single unit. That is, the medium perimeter wall 10 and the internal frame 11 are integrally molded, and the medium perimeter wall 10 and the internal frame 11 may be integrally molded using the same material. In this way, the molding method is simple, and it is easy for the internal frame 11 to provide structural support to the medium perimeter wall 10 during molding, thereby improving the structural stability of the aerosol-generating medium 1. By using the same material for the internal frame 11 and the medium perimeter wall 10, the content of the aerosol-generating substrate can be increased, and both the internal frame 11 and the medium perimeter wall 10 can be atomized by heat received by the laser heating unit, allowing aerosols to be released toward the airway holes 10a, thereby increasing atomization efficiency and aerosol generation amount, and improving the user experience.

[0073] In some other embodiments, the aerosol-generating medium 1 is a separate structure, where the medium perimeter wall 10 and the internal frame 11 are formed as two independent units and assembled as the aerosol-generating medium 1 after molding. The medium perimeter wall 10 and the internal frame 11 may be made of the same material or different materials.

[0074] In some embodiments, the aerosol-generating medium 1 is a single-piece extruded structure.

[0075] Extrusion molding is a molding method that uses the pressing action of a screw or plunger to extrude a polymer material that has been melted by heat absorption under pressure, forcing it through a die head mold to form a continuous molded material with a constant cross-section. In this embodiment, the aerosol generating medium 1 employs an integral extrusion molding method, resulting in high production efficiency, a fast molding speed, and low production costs.
