Description

Technical Field

[0001] The utility model relates to the field of atomization, in particular to an aerosol generating article and an aerosol generating matrix. Background Art

[0002] The heating temperature of a heat-not-burn appliance is relatively low. Compared with traditional aerosol generating matrices, it can effectively reduce harm and restore the original flavor of the aerosol generating matrix to the greatest extent. Currently, the mainstream aerosol generating matrices on the market are cylindrical; for a cylindrical aerosol generating matrix, its diameter is usually 6-8 mm, and the number of puffs per single aerosol generating matrix is small. If a large number of puffs are required, a new aerosol generating matrix needs to be replaced. Replacing a new aerosol generating matrix requires frequent picking up and plugging, and there is generally a preheating waiting time. The speed of generating aerosol is slow, the aerosol volume and flavor decay in the latter stage of puffing, and the consistency of the taste per puff is poor. The main reason is that the heat conduction path in the diameter direction of the cylindrical aerosol generating matrix is long, the volume of the matrix body is small, the utilization rate of the matrix body is low, and its inherent morphological characteristics cause many drawbacks in both the appliance and the sensory experience.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0051] Figure 1 and Figure 2 shows a first embodiment of the aerosol-generating article of the present utility model. The aerosol-generating article can be installed on an aerosol-generating device and is used to generate aerosol when heated. The aerosol-generating article can be detachably assembled with the aerosol-generating device, thereby facilitating the replacement of the aerosol-generating article. The aerosol-generating device can atomize the aerosol-generating matrix in the aerosol-generating article by heating to generate aerosol.

[0052] As Figure 1 and Figure 2 shown, the aerosol-generating article can include a cartridge 1 and an aerosol-generating matrix 2. The cartridge 1 can be used to accommodate the aerosol-generating matrix 2. The aerosol-generating matrix 2 can be atomized to generate aerosol in a heated state. It can be understood that in some other embodiments, the cartridge 1 can be omitted. The aerosol-generating matrix 2 can be directly installed in the aerosol-generating device.

[0053] In this embodiment, the cartridge 1 can be a transparent structure, such as a transparent plastic box. Combining with the transparent and visible cartridge, the heating, transmission and operation states of the aerosol-forming substrate 2 can be observed, increasing the user's interest in use. Of course, it can be understood that in some embodiments, the cartridge 1 is not limited to being 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 cartridge 1 may include a first cartridge 1a and a second cartridge 1b; the shapes and sizes of the first cartridge 1a and the second cartridge 1b are comparable. In some embodiments, the first cartridge 1a and the second cartridge 1b are generally in the shape of a cuboid. The first cartridge 1a and the second cartridge 1b are not limited to being in the shape of a cuboid, such as a columnar cube shape or an irregular shape, etc. Cavities are formed inside both the first cartridge 1a and the second cartridge 1b, and both are open structures. The first cartridge 1a and the second cartridge 1b can be joined by fitting the side with an opening of the first cartridge 1a to the side with an opening of the second cartridge 1b. The first cartridge 1a and the second cartridge 1b can be connected and fixed by setting a connection structure, and the connection structure can be a screwing component, a clamping component or others. In some embodiments, the connection structure can also be omitted, and the first cartridge 1a and the second cartridge 1b can be connected by using conventional ultrasonic technology. An atomization chamber 10 is formed in the cartridge 1, and an air passage 11 communicating with the atomization chamber 10 is provided on the cartridge 1. In this embodiment, the aerosol-forming substrate 2 can move through the atomization chamber 10 and be heated in the atomization chamber 10 to generate aerosol, and the generated aerosol can be output through the air passage 11.

[0054] As Figures 3 to 5 shown, in this embodiment, the aerosol-forming substrate 2 is integrally strip-shaped and can be wound. It may include a support 21 and a substrate body 22. The support 21 can be flexible and longitudinally long. The substrate body 22 is arranged on the support 21 and is continuously arranged along the length direction of the support 21. In some other embodiments, it can also be arranged at intervals along the length direction of the support 21. By using the flexible support 21 to support the substrate body 22, a flexible aerosol-forming substrate 2 can be formed, and it is convenient for the formed aerosol substrate 2 to move and wind, increasing the accommodation capacity of the substrate body 22, enabling multiple puffs of inhalation without frequent replacement, being beneficial to uniform heating, improving the atomization sufficiency, aerosol generation efficiency and the utilization rate of the substrate body, and ensuring the consistency of the inhalation taste.

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

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

[0057] In this embodiment, the support 21 is made of a metal foil, such as aluminum foil. In some other embodiments, the support 21 can also be a non-woven fabric, or a combination of a non-woven fabric and a metal foil, or a combination of other non-woven fabric-like materials and a metal foil. In this embodiment, at least a part of the support 21 is a solid structure. Specifically, the support 21 can be a solid structure as a whole. Of course, it can be understood that in some other embodiments, the support 21 can be partially solid, partially hollow, or hollow as a whole. 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 arranged back to back, and the first surface 21a and the second surface 21b can be defined by the long side and the wide side of the support 21.

[0058] In this embodiment, the thickness of the support 21 can be 6 - 50 um (including the two end values). Further, the thickness of the support 21 can be selected as 10 - 30 um (including the two end values). Specifically, it can be 15 um. In this embodiment, the width of the support 21 can be 1 - 20 mm (including the two end values), and the width of the support 21 can be further selected as 3 - 8 mm (including the two end values). Specifically, it can be selected as 5 mm. By adopting the thickness and width of the above dimensions, it can be ensured that the support 21 not only has a certain support strength, but also can carry as many substrate bodies 22 as possible, and is convenient for the movement or winding of the aerosol-forming substrate 2 formed later.

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

[0060] In this embodiment, the thickness of the matrix body 22 can be greater than or equal to the thickness of the support body 21. Specifically, the thickness of the matrix body 22 on the first surface 21a of the support body 21 can be greater than the thickness of the support body 21, and the thickness of the matrix body 22 on the second surface 21b of the support body 21 can be greater than the thickness of the support body 21. In some other embodiments, the thickness of the matrix body 22 on the first surface 21a of the support body 21 can be equal to the thickness of the matrix body 22 on the second surface 21b of the support body 21. It can be understood that in some other embodiments, the thickness of the matrix body 22 on the first surface 21a of the support body 21 can also be different from the thickness of the matrix body 22 on the second surface 21b of the support body 21. In some embodiments, the taste of the matrix body 22 on the first surface 21a of the support body 21 can be the same as the taste of the matrix body 22 on the second surface 21b of the support body 21. In some other embodiments, the components and tastes of the two can also be different, so as to make the taste more diverse and rich. In some embodiments, the thickness of the matrix body 22 on the surface of the support body 21 can be 10 - 500 μm (including the two end values). Further, the thickness of the matrix body 22 on the first surface 21a can be selected to be 100 - 360 μm (including the two end values); the thickness of the matrix body 22 on the second surface 21b can be selected to be 100 - 360 μm (including the two end values). Specifically, the thickness of the matrix body 22 on the first surface 21a can be 280 - 300 μm (including the two end values); the thickness of the matrix body 22 on the second surface 21b can be selected to be 280 - 300 μm (including the two end values).

[0061] In this embodiment, the thickness of the matrix body 22 in the length direction of the support body 21 is uniformly set. In some other embodiments, the thickness of the matrix body 22 on the support body 21 can also be non-uniformly set. For example, the thickness of some segments can be greater than that of other segments. In the length direction of the support body 21, the formulations and tastes of the matrix body 22 in different segments can be the same or different, so as to produce a better baking effect and create a more rich taste.

[0062] In the present embodiment, the aerosol carrying out mode of the matrix body 22 can be selected as positive atomization, that is, the matrix body 22 that is located at the first surface 21a and the surface that is arranged opposite to the second surface 21b can be used as the atomization surface. When the aerosol generating matrix 2 penetrates the atomizing chamber 10 and passes through the induced magnetic field, when the support body 21 induces the electromagnetic field to heat the matrix body 22, the matrix body 22 of the first surface 21a can be directly opposite to the airway 11 outlet positions, and after the aerosol escapes, it can be smoothly carried out by the airflow, that is, by arranging the matrix body 22 on the first surface 21a toward the airway 11 outlets, the aerosol produced by the matrix body 22 is prevented from being hindered by the support body 21 and the wall surface that easily hits the box body 1 loses kinetic energy and causes condensation, improves the efficiency of carrying out the aerosol, and improves the aerosol amount and ensures fragrance.

[0063] In this embodiment, the aerosol generating product may further include a storage structure 3 and a receiving structure 4. The storage structure 3 may be used to store the un-atomized aerosol generating substrate 2, which may be a storage wheel, on which the un-atomized aerosol generating substrate 2 may be wound, and the aerosol generating substrate 2 may be moved through the atomizing chamber 10 through the unwinding and the guidance of the guide structure. The receiving structure 4 is used to receive the atomized aerosol generating substrate 2, which may be a receiving wheel, on which the atomized aerosol generating substrate 2 may be wound.

[0064] By coating the matrix body 22 on both sides or multiple sides of the support body 21, the thickness of the matrix body 22 on each side can be reduced, so that the overall aerosol generating matrix 2 is thinner, and the heating is more uniform, the atomization is more complete, the utilization rate of the matrix body 22 is higher, the taste consistency is better, and the heat of the support body 21 can be fully utilized, resulting in lower energy consumption of the product. Most importantly, more combinations can be achieved. For example, the thickness of the matrix body 22 on the two surfaces can be different, and different flavors can be atomized and mixed at the same time, which brings different smoking experiences, and can also increase the number of puffs while saving consumables.

[0065] The aerosol generating matrix 2 can achieve multiple puffs without frequent replacement. By continuously moving the matrix body 22, a fresh matrix body 22 can be replaced after each puff, thereby achieving the advantage of consistent taste from puff to puff. 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 medium utilization rate and the aerosol generation speed.

[0066] Figures 6 to 9Figure 2 shows a second embodiment of the aerosol-generating article of the present utility model. The difference between this embodiment and the first embodiment is that a plurality of through holes 211 may be provided on the support body 21. The plurality of through holes 211 may be spaced apart, and each through hole 211 may penetrate through the support body 21 in the thickness direction thereof. In this embodiment, the cross-sectional shape of the through hole 211 may be a regular shape, such as a circle, an ellipse, or a rectangle. In some embodiments, the through hole 211 may also be selected to be a special shape, such as a gear shape, a pentagram shape, or a heart shape. In some other embodiments, the cross-sectional shape of the through hole 211 may also be an irregular shape, such as an irregular quadrilateral. In this embodiment, the matrix body 22 may be at least partially embedded in the support body 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 the plurality of through holes 211, the matrix body 22 can be surrounded on multiple sides, thereby realizing multi-sided three-dimensional heating. The heat conduction path is short, and the heat loss is small, making the heating efficiency higher, the matrix body 22 heated more uniformly, the release rate of the active ingredient higher, improving the utilization rate of the matrix body 22 and the fragrance excitation effect.

[0067] Figures 10 to 11 Figure 3 shows a third embodiment of the aerosol-generating article of the present utility model. The difference between this embodiment and the first embodiment is that the support body 21 may be at least two layers. Specifically, the support body 21 may be two layers, and the two support bodies 21 are stacked, and they may be fixedly adhered by providing an adhesive member 23 therebetween. The matrix body 22 may be provided on the surface of the support body 21 facing away from the other support body 21. By providing the matrix body 22 on both sides, the thickness of the matrix body 22 on each side can be made thinner, so that the heating is more uniform, the atomization is more sufficient, the utilization rate of the matrix body 22 is higher, the number of puffs is increased, and the consistency of the taste of the generated aerosol is better.

[0068] Figures 12 to 14 Figure 4 shows a fourth embodiment of the aerosol-generating matrix of the present utility model. The difference between this embodiment and the second embodiment is that the entire support body 21 may be made of non-woven fabric. By using non-woven fabric, the overall manufacturing cost can be reduced. The cross-sectional shape of the through hole 211 on the support body 21 may be generally diamond-shaped, which is beneficial to the embedding of the matrix body 22 in the non-woven fabric, thereby improving the bonding tightness between the matrix body 22 and the support body 21. The matrix body 22 can be in a multi-sided surrounding state, and thus multi-sided three-dimensional heating can be realized. The heat conduction path is short, and the heat loss is small, making the heating efficiency higher, the matrix body 22 heated more uniformly, the release rate of the active ingredient higher, improving the utilization rate of the matrix body 22 and the fragrance excitation effect.

[0069] In some other embodiments, the support 21 is not limited to being strip-shaped. It can be bar-shaped, and its cross-sectional shape can be a regular shape, such as circular, oval, rectangular, etc. In some embodiments, it can also be a special shape, such as a pentagram shape, a gear shape, etc. In some other embodiments, the cross-section of the support 21 can also be an irregular shape, such as an irregular quadrilateral. There can be multiple supports 21, and the multiple supports 21 can be intertwined to form a network structure. Of course, it can be understood that in some other embodiments, the supports 21 can also be arranged at intervals and side by side, and can be fixed by fixing members. By forming intervals between the supports 21, it is beneficial for the matrix body 22 to be embedded in the intervals between the supports 21, wrapping the supports 21 from multiple sides, thereby improving the heating uniformity and heating effect.

[0070] Figures 15 to 16 The fifth embodiment of the aerosol-generating article of the present invention is shown. The difference from the first embodiment is that the matrix body 22 can be provided only on one surface of the support 21, and the support 21 and the matrix body 22 can be wound together to form a hollow columnar aerosol-generating matrix. The wound matrix body 22 can be located on the outer surface of the support 21. Forming a hollow columnar aerosol-generating matrix 2 is beneficial for adapting to a non-tape-type aerosol-generating device, and is also beneficial for rotatably arranging the entire aerosol-generating matrix 2, thereby improving the heating uniformity.

[0071] Figures 17 to 19 The sixth embodiment of the aerosol-generating article of the present invention is shown. The difference from the fifth embodiment is that a plurality of protrusions 212 are arranged at intervals in the length direction on one surface of the support 21. The plurality of protrusions 212 can be strip-shaped and can extend along the width direction of the support 21. The matrix body 22 is at least partially embedded in the interval between two adjacent protrusions 212 arranged adjacent to each other, that is, the interval between two adjacent protrusions 212 can be filled with the matrix body 22, that is, the matrix body 22 can be arranged discontinuously and non-uniformly. The flavors of the matrix body 22 filled in each interval can be the same or different, so that the taste can be more diverse and rich, improving the user experience.

[0072] Figure 20The seventh embodiment of the aerosol generating product of the utility model is shown. The difference between the seventh embodiment and the first embodiment is that the airway 11 is arranged relative to the side surface of the aerosol generating substrate 2 (the surface between the first surface 21a and the second surface 21b). Specifically, the airway 11 can be arranged opposite to the first side surface 2a defined by the long side and the thick side of the aerosol generating substrate 2. The substrate body 22 on the first surface 21a and the substrate body 22 on the second surface 21b can be heated and atomized at the same time when passing through the atomizing chamber 10 and being in the U-shaped / C-shaped electromagnetic induction magnetic field. The aerosol generated by the two can be output along the airway 22. The aerosol will not be blocked by the support 21, and because the airway 11 is facing the side surface of the aerosol generating substrate 2, the aerosol can be smoothly taken out. By selecting a suitable heating method and aerosol taking-out method for the aerosol generating substrate 2 used, the obvious advantages of the aerosol generating substrate 2 of the utility model can be maximized.

[0073] Figure 21 The eighth embodiment of the aerosol generating product of the utility model is shown. The difference between the eighth embodiment and the seventh embodiment is that the air channel 11 is arranged opposite to the other side of the aerosol generating substrate 2. Specifically, the air channel 11 can be arranged opposite to the second side 2b defined by the wide side and the thick side of the aerosol generating substrate 2, which is beneficial to improving the output efficiency of the aerosol.
