Description

Technical Field

[0001] This invention relates to the field of atomization, and more particularly to aerosol generating products and aerosol generating matrices. Background Technology

[0002] Heated non-combustible (HNC) appliances have lower heating temperatures, which effectively reduces harm compared to traditional aerosol generating substrates and preserves the original aroma of the aerosol generating substrate to the greatest extent. Currently, the mainstream aerosol generating substrates on the market are cylindrical. However, cylindrical aerosol generating substrates typically have a diameter of 6-8mm, resulting in fewer puffs per unit. If multiple puffs are required, a new aerosol generating substrate needs to be replaced. Replacing the substrate requires frequent handling and insertion / removal, and there are generally issues such as preheating, slow aerosol generation, reduced aerosol volume and aroma in the later stages of puffing, and poor consistency in taste between puffs. The main reason for this is that the cylindrical aerosol generating substrate has a long heat conduction path along its diameter, a small substrate volume, and low substrate utilization. Its inherent shape characteristics cause many drawbacks in both the appliance and the sensory experience. Summary of the Invention

The terms "first," "second," etc., are used only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0051] Figure 1 and Figure 2 A first embodiment of the aerosol generating article of the present invention is shown. The aerosol generating article can be mounted on an aerosol generating device for generating aerosols upon heating. The aerosol generating article is detachably assembled with the aerosol generating device, thereby facilitating replacement of the aerosol generating article. The aerosol generating device generates aerosols by heating the aerosol generating matrix in the aerosol generating article to atomize it.

[0052] like Figure 1 and Figure 2 As shown, the aerosol generating article may include a housing 1 and an aerosol generating matrix 2. The housing 1 can be used to house the aerosol generating matrix 2. The aerosol generating matrix 2 can be atomized to generate aerosols under heating. Understandably, in some other embodiments, the housing 1 may be omitted. The aerosol generating matrix 2 can be directly installed in the aerosol generating device.

[0053] In this embodiment, the box 1 can be a transparent structure, such as a transparent plastic box. The transparent and visible box allows for observation of the heating, transmission, and operation of the aerosol generating matrix 2, increasing user enjoyment. Of course, it is understood that in some embodiments, the box 1 is not limited to a transparent structure and can be a non-transparent structure, such as a non-transparent plastic box or a metal box. In this embodiment, the box 1 may include a first box 1a and a second box 1b; the first box 1a and the second box 1b have similar shapes and sizes, and in some embodiments, they are generally cuboid in shape. The first box 1a and the second box 1b are not limited to a cuboid shape; they can also be columnar cubes or irregular shapes. Both the first box 1a and the second box 1b have cavities formed on their inner sides, and both are open structures, allowing for the joining of the open sides of the first box 1a and the second box 1b. The first housing 1a and the second housing 1b can be connected and fixed by a connecting structure, which can be a screw assembly, a snap-fit ​​assembly, or others. In some embodiments, this connecting structure can be omitted, and the first housing 1a and the second housing 1b can be connected using conventional ultrasonic technology. An atomizing chamber 10 is formed in the housing 1, and an air passage 11 communicating with the atomizing chamber 10 is provided on the housing 1. In this embodiment, the aerosol generating matrix 2 can move through the atomizing chamber 10 and is heated in the atomizing chamber 10 to generate aerosol, which can be output through the air passage 11.

[0054] like Figures 3 to 5 As shown, in this embodiment, the aerosol generating matrix 2 is generally strip-shaped and can be wound up. It may include a support body 21 and a matrix body 22. The support body 21 can be flexible and longitudinally elongated. The matrix body 22 is disposed on the support body 21 and is continuously disposed along the length direction of the support body 21. In some other embodiments, it may also be disposed at intervals along the length direction of the support body 21. By using the flexible support body 21 to support the matrix body 22, a flexible aerosol generating matrix 2 can be formed. It is also convenient for the formed aerosol matrix 2 to move and be wound up, increasing the capacity of the matrix body 22, enabling multiple puffs without frequent replacement, facilitating uniform heating, improving the atomization sufficiency, aerosol generation efficiency, and matrix body utilization, and ensuring the consistency of the puffing taste.

[0055] In this embodiment, the support 21 can be strip-shaped. Specifically, the support 21 is a long, thin strip, and its cross-sectional shape can be roughly regular, such as rectangular. Of course, it is understood that in other embodiments, the cross-sectional shape of the support 21 is not limited to rectangular; it can be circular, elliptical, T-shaped, trapezoidal, parallelogram, etc. In some embodiments, the cross-sectional shape of the support 21 can also be irregular, such as a pentagonal, gear, or heart shape. In other embodiments, the cross-section of the support 21 can also be irregular, such as an irregular quadrilateral.

[0056] In this embodiment, the material of the support 21 can be a magnetic induction material or contain magnetic induction materials. It can generate heat by inducing a magnetic field, thereby heating the substrate 22 located thereon. In other embodiments, the material of the support 21 can also be a material that can be heated by contact or non-contact heating methods such as resistance, infrared, microwave, and laser.

[0057] In this embodiment, the support 21 is made of metal foil, such as aluminum foil. In other embodiments, the support 21 may also be non-woven fabric, or a combination of non-woven fabric and metal foil, or a combination of other similar non-woven materials and metal foil. In this embodiment, the support 21 is at least partially solid; specifically, the support 21 may be entirely solid. Of course, it is understood that in other embodiments, the support 21 may be partially solid, partially hollow, or entirely hollow. In this embodiment, the support 21 has at least a first surface 21a and a second surface 21b; the first surface 21a and the second surface 21b are opposite to each other, and the first surface 21a and the second surface 21b may define the long side and the wide boundary of the support 21.

[0058] In this embodiment, the thickness of the support 21 can be 6-50 μm (including both ends), and further, the thickness of the support 21 can be selected as 10-30 μm (including both ends), specifically, it can be 15 μm. In this embodiment, the width of the support 21 can be 1-20 mm (including both ends), and the width of the support 21 can be further selected as 3-8 mm (including both ends), specifically, it can be selected as 5 mm. By adopting the above-mentioned thickness and width, it can be ensured that the support 21 not only has a certain supporting strength, but also can support as much matrix body 22 as possible, and can facilitate the movement or winding of the formed aerosol generation matrix 2.

[0059] In this embodiment, the matrix body 22 can be disposed on at least one surface of the support 21 by means of casting, dip coating, or spraying. Specifically, the matrix body 22 can be disposed on at least two surfaces of the support 21; the matrix body 22 can be disposed on the first surface 21a and the second surface 21b of the support 21. Of course, it is understood that in some other embodiments, the matrix body 22 can be disposed on only one surface of the support 21 or cover the outer periphery of the support 21. In some embodiments, the matrix body 22 can be a liquid and curable atomizing medium made from the leaves and / or stems of plants (e.g., tobacco), or it can be a paste-like atomizing medium or a solid atomizing medium.

[0060] In this embodiment, the thickness of the matrix body 22 can be greater than or equal to the thickness of the support 21. Specifically, the thickness of the matrix body 22 on the first surface 21a of the support 21 can be greater than the thickness of the support 21, and the thickness of the matrix body 22 on the second surface 21b of the support 21 can be greater than the thickness of the support 21. In other embodiments, the thickness of the matrix body 22 on the first surface 21a of the support 21 can be equal to the thickness of the matrix body 22 on the second surface 21b of the support 21. Understandably, in other embodiments, the thickness of the matrix body 22 on the first surface 21a of the support 21 can also be unequal to the thickness of the matrix body 22 on the second surface 21b of the support 21. In some embodiments, the flavor of the matrix body 22 on the first surface 21a of the support 21 can be the same as the flavor of the matrix body 22 on the second surface 21b of the support 21. In other embodiments, their components and flavors can also be different, thereby making the taste more diverse and richer. In some embodiments, the thickness of the matrix body 22 on the surface of the support 21 can be 10-500 μm (including the values ​​at both ends). Further, the thickness of the matrix body 22 on the first surface 21a can be selected as 100-360 μm (including the values ​​at both ends); the thickness of the matrix body 22 on the second surface 21b can be selected as 100-360 μm (including the values ​​at both ends). Specifically, the thickness of the matrix body 22 on the first surface 21a is 280 μm-300 μm (including the values ​​at both ends); the thickness of the matrix body 22 on the second surface 21b can be selected as 280 μm-300 μm (including the values ​​at both ends).

[0061] In this embodiment, the thickness of the matrix body 22 along the length of the support 21 is uniform. In other embodiments, the thickness of the matrix body 22 along the support 21 may be non-uniform, for example, the thickness of some sections may be greater than the thickness of other sections. Along the length of the support 21, the formula and flavor of the matrix body 22 in different sections may be the same or different, thereby producing better baking results and creating a richer taste.

[0062] In this embodiment, the aerosol carry-out method of the matrix body 22 can be selected as front atomization, that is, the surface of the matrix body 22 located on the first surface 21a and the second surface 21b that are set opposite to each other can be used as the atomization surface. When the aerosol generating matrix 2 enters the atomization chamber 10 and passes through the induced magnetic field, and the support 21 is heated by the induced electromagnetic field, the matrix body 22 on the first surface 21a can be directly opposite the outlet of the air channel 11. After the aerosol escapes, it can be smoothly carried out by the airflow. That is, by setting the matrix body 22 on the first surface 21a toward the outlet of the air channel 11, the aerosol generated by the matrix body 22 is prevented from being obstructed by the support 21 and from easily hitting the wall of the box 1 and losing kinetic energy, thus causing condensation. This improves the aerosol carry-out efficiency, increases the amount of aerosol, and ensures the aroma.

[0063] In this embodiment, the aerosol generating product may further include a storage structure 3 and a receiving structure 4. The storage structure 3 can be used to store the un-atomized aerosol generating matrix 2. It can be a storage wheel on which the un-atomized aerosol generating matrix 2 can be wound, and the aerosol generating matrix 2 can be moved through the atomization chamber 10 by unwinding and guiding the structure. The receiving structure 4 is used to receive the atomized aerosol generating matrix 2. It can be a receiving wheel on which the atomized aerosol generating matrix 2 can be wound.

[0064] By coating the support body 21 with the matrix body 22 on both or multiple sides, the thickness of the matrix body 22 on each side can be reduced, resulting in a thinner overall aerosol generation matrix 2, more uniform heating, more complete atomization, higher utilization of the matrix body 22, better consistency of taste, and full utilization of the heat of the support body 21, leading to lower energy consumption of the product. Most importantly, it can achieve more combination variations, such as different thicknesses of the matrix body 22 on the two surfaces, and different flavors can be atomized and mixed at the same time to bring different vaping experiences, increase the number of puffs, and save consumables.

[0065] The aerosol generating matrix 2 can achieve multiple suctions without frequent replacement. By continuously moving the matrix body 22, a fresh matrix body 22 can be replaced after each suction, achieving the advantage of consistent taste with each suck. The aerosol generating matrix 2 can reduce the heat conduction path by adjusting the total thickness and distribution, thereby achieving the purpose of fully baking, improving the utilization rate of the medium and the speed of aerosol generation.

[0066] Figures 6 to 9A second embodiment of the aerosol-generated article of the present invention is shown, which differs from the first embodiment in that a plurality of through holes 211 may be provided on the support 21. The plurality of through holes 211 may be spaced apart, and each through hole 211 may extend through the support 21 along its thickness direction. In this embodiment, the cross-sectional shape of the through hole 211 may be a regular shape, such as a circle, ellipse, or rectangle. In some embodiments, the through hole 211 may also be irregular in shape, such as a gear shape, a pentagram shape, or a heart shape. In other embodiments, the cross-sectional shape of the through hole 211 may also be irregular, such as an irregular quadrilateral. In this embodiment, the matrix body 22 may be at least partially embedded in the support 21. Specifically, the matrix body 22 on the first surface 21a may be partially embedded in the through hole 211 and connected to the matrix body 22 on the second surface 21b. Through multiple through holes 211, the matrix body 22 can be surrounded on multiple sides, thereby achieving multi-faceted three-dimensional heating. Its heat conduction path is short and heat loss is small, resulting in higher heating efficiency, more uniform heating of the matrix body 22, higher release rate of effective ingredients, and improved utilization rate and aroma activation effect of the matrix body 22.

[0067] Figures 10 to 11 The third embodiment of the aerosol-generating article of the present invention is shown. The difference from the first embodiment is that the support 21 can have at least two layers. Specifically, the support 21 can have two layers, stacked together, and fixed together by an adhesive member 23. A matrix body 22 can be provided on the surface of the support 21 opposite to the other support 21. By providing the matrix body 22 on both sides, the thickness of the matrix body 22 on each side can be thinner, resulting in more uniform heating, more complete atomization, higher utilization of the matrix body 22, increased number of suction ports, and better consistency in the taste of the generated aerosol.

[0068] Figures 12 to 14 A fourth embodiment of the aerosol-generating matrix of the present invention is shown, which differs from the second embodiment in that the support 21 can be made entirely of non-woven fabric. Using non-woven fabric reduces the overall manufacturing cost. The cross-sectional shape of the through holes 211 on the support 21 can be approximately rhomboid, which facilitates the embedding of the matrix body 22 into the non-woven fabric, thereby improving the tightness of the bond between the matrix body 22 and the support 21. The matrix body 22 can be multi-faceted, thus enabling multi-faceted three-dimensional heating. This results in a shorter heat conduction path, less heat loss, higher heating efficiency, more uniform heating of the matrix body 22, a higher release rate of effective components, and improved utilization and aroma activation effects of the matrix body 22.

[0069] In other embodiments, the support 21 is not limited to being strip-shaped; it can be strip-shaped, and its cross-sectional shape can be regular, such as circular, elliptical, or rectangular. In some embodiments, it can also be irregularly shaped, such as a pentagon or gear. In other embodiments, the cross-section of the support 21 can also be irregularly shaped, such as an irregular tetrahedron. There can be multiple supports 21, and these supports 21 can be interwoven to form a mesh structure. Of course, it is understood that in other embodiments, the supports 21 can also be spaced apart and arranged side by side, and can be fixed by fasteners. The gaps between the supports 21 facilitate the embedding of the substrate body 22 into the gaps between the supports 21, allowing the substrate body 22 to wrap around the supports 21 from multiple sides, thereby improving heating uniformity and heating effect.

[0070] Figures 15 to 16 A fifth embodiment of the aerosol generating article of the present invention is shown, which differs from the first embodiment in that the matrix body 22 may be disposed on only one surface of the support 21, and the support 21 and the matrix body 22 may be wound together to form a hollow columnar aerosol generating matrix. The wound matrix body 22 may be located on the outer surface of the support 21. Forming a hollow columnar aerosol generating matrix 2 facilitates adaptation to non-magnetic aerosol generating devices and also facilitates the rotational setting of the entire aerosol generating matrix 2, thereby improving the uniformity of heating.

[0071] Figures 17 to 19 A sixth embodiment of the aerosol-generated article of the present invention is shown, which differs from the fifth embodiment in that a plurality of protrusions 212 are spaced apart along the length of one surface of the support 21. These protrusions 212 may be strip-shaped and extend along the width of the support 21. The matrix body 22 is at least partially embedded in the gap between two adjacent protrusions 212, meaning the gap between two adjacent protrusions 212 can be filled with the matrix body 22. This means the matrix body 22 may be discontinuous and non-uniformly arranged, and the flavor of the matrix body 22 filled in each gap may be the same or different, thereby making the taste more diverse and richer, and improving the user experience.

[0072] Figure 20A seventh embodiment of the aerosol-generating article of the present invention is shown, which differs from the first embodiment in that the air passage 11 is arranged opposite to the side surface (the surface between the first surface 21a and the second surface 21b) of the aerosol-generating matrix 2. Specifically, the air passage 11 may be directly opposite the first side surface 2a defined by the long side and the thick side of the aerosol-generating matrix 2. The matrix body 22 on the first surface 21a and the matrix body 22 on the second surface 21b can be simultaneously heated and atomized when passing through the atomization chamber 10 and being in a U-shaped / C-shaped electromagnetic induction magnetic field. The aerosols generated by both can be output along the air passage 22. The aerosols are not obstructed by the support 21, and since the air passage 11 is directly opposite the side surface of the aerosol-generating matrix 2, the aerosols can be smoothly carried out. By selecting a suitable heating method and aerosol carry-out method for the aerosol-generating matrix 2 used, the obvious advantages of the aerosol-generating matrix 2 of the present invention can be maximized.

[0073] Figure 21 The eighth embodiment of the aerosol generating article of the present invention is shown. The difference between the eighth and seventh embodiments is that the air passage 11 is arranged opposite to the other side of the aerosol generating matrix 2. Specifically, the air passage 11 can be arranged directly opposite to the second side 2b defined by the wide side and the thick side of the aerosol generating matrix 2, which is beneficial to improving the output efficiency of aerosol.
