Description

Aerosol generating article and aerosol generating substrate TECHNICAL FIELD

[0001] The present application relates to the field of atomization, in particular to an aerosol generating article and an aerosol generating substrate. BACKGROUND

[0002] The heating temperature of a heat-not-burn device is relatively low, which can effectively reduce harm and maximize the reduction of the original flavor of the aerosol generating substrate. The mainstream aerosol generating substrate on the market is in a cylindrical shape. The diameter of the cylindrical aerosol generating substrate is usually 6-8 mm, and the number of ports of a single aerosol generating substrate is small. If multiple ports are needed, a new aerosol generating substrate needs to be replaced. The new aerosol generating substrate needs to be frequently taken out and plugged in, and there is generally a preheating waiting period. The aerosol generation speed is slow, the aerosol amount and the flavor of the latter part of the puffing are attenuated, and the consistency of the puffing experience of each port is poor. The main reason is that the heat conduction path in the diameter direction of the cylindrical aerosol generating substrate is long, the capacity of the substrate body is small, the utilization rate of the substrate body is low, and the inherent morphological characteristics of the substrate body cause many disadvantages in the device and the sensory experience.

[0051] Fig. 1 and Fig. 2 show a first embodiment of the aerosol generating article of the present application, which can be mounted on an aerosol generating device for generating aerosol when heated. The aerosol generating article can be detachably assembled with the aerosol generating device, thereby facilitating replacement of the aerosol generating article. The aerosol generating device can generate aerosol by heating the aerosol generating substrate in the aerosol generating article to atomize it.

[0052] As shown in Fig. 1 and Fig. 2, the aerosol generating article can include a cartridge 1 and an aerosol generating substrate 2.

[0053] In the present embodiment, the cartridge 1 can be a transparent structure, such as a transparent plastic cartridge. In combination with the transparent and visible cartridge, the heating, transmission and running state of the aerosol generating substrate 2 can be observed, thereby increasing the user's interest in use. Of course, it is understood that in some embodiments, the cartridge 1 is not limited to a transparent structure, but can be a non-transparent structure, such as a non-transparent plastic cartridge or a metal cartridge.

The first cartridge 1a and the second cartridge 1b can be connected and fixed by a connecting structure, which can be a screwing assembly, a clamping assembly or other. In some embodiments, the connecting structure can also be omitted, and the first cartridge 1a and the second cartridge 1b can be connected by conventional ultrasonic technology. The cartridge 1 is formed with an atomization cavity 10, and the cartridge 1 is provided with an air passage 11 communicating with the atomization cavity 10. In the present embodiment, the aerosol generating substrate 2 can move through the atomization cavity 10 and be heated to generate aerosol in the atomization cavity 10, and the generated aerosol can be output through the air passage 11.

[0054] As shown in FIGS. 3-5, in the present embodiment, the aerosol generating substrate 2 is in the form of a strip as a whole and can be wound, and can include a support body 21 which can be flexible and elongated, and a substrate body 22 which is provided on the support body 21 and is continuously provided along the length direction of the support body 21, or is provided in the length direction of the support body 21 at intervals in some other embodiments. By using the flexible support body 21 to support the substrate body 22, a flexible aerosol generating substrate 2 can be formed, and the formed aerosol generating substrate 2 can be moved and wound, the capacity of the substrate body 22 can be increased, multiple puffs can be achieved without frequent replacement, uniform heating can be facilitated, and the atomization sufficiency, aerosol generation efficiency, and substrate body utilization rate can be improved, and the consistency of the puffing taste can be ensured.

[0055] In the present embodiment, the support body 21 can be in the form of a strip, specifically, the support body 21 is in the form of a thin strip which is elongated, and the cross-sectional shape thereof can be substantially regular, such as a rectangle. Of course, it can be understood that in some other embodiments, the cross-sectional shape of the support body 21 can not be limited to a rectangle, and can be a circle, an ellipse, a T shape, a trapezoid, a parallelogram, and the like. In some embodiments, the cross-sectional shape of the support body 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-sectional shape of the support body 21 can also be irregular, such as an irregular quadrilateral.

[0056] In the present embodiment, the material of the support body 21 can be selected to be a magnetic induction material or contain a magnetic induction material. The support body 21 can generate heat by induction of a magnetic field to heat the substrate body 22 located thereon. In some other embodiments, the material of the support body 21 can also be a material which can be heated by resistance, infrared, microwave, laser, and the like, in contact or non-contact heating modes.

[0057] In the present embodiment, the support body 21 is in the form of a metal foil, such as an aluminum foil. In some other embodiments, the support body 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 similar non-woven fabric materials and a metal foil. In the present embodiment, the support body 21 is at least partially in the form of a solid structure, specifically, the support body 21 can be in the form of a solid structure as a whole. Of course, it can be understood that in some other embodiments, the support body 21 can be partially solid, partially hollow, or in the form of a hollow structure as a whole. In the present embodiment, the support body 21 has at least a first surface 21a and a second surface 21b which are oppositely arranged, and the first surface 21a and the second surface 21b can be defined by the length and width of the support body 21.

[0058] In the present embodiment, the thickness of the support body 21 can be 6-50 um (including the two end values), further, the thickness of the support body 21 can be selected to be 10-30 um (including the two end values), specifically, it can be 15 um. In the present embodiment, the width of the support body 21 can be 1-20 mm (including the two end values), the width of the support body 21 can be further selected to be 3-8 mm (including the two end values), specifically, it can be selected to be 5 mm. By adopting the above-mentioned size of thickness and width, it can be ensured that the support body 21 not only has a certain supporting strength, but also can carry as many matrix bodies 22 as possible, and can facilitate the movement or winding of the formed aerosol generating substrate 2.

[0059] In the present embodiment, the matrix body 22 can be arranged on at least one surface of the support body 21 by flow casting, dip coating or spray coating and the like, specifically, the matrix body 22 can be arranged on at least two surfaces of the support body 21; the matrix body 22 can be arranged on the first surface 21a and the second surface 21b of the support body 21. Of course, it can be understood that in other embodiments, the matrix body 22 can be arranged on only one surface of the support body 21 or wrapped around the outer periphery of the support body 21. In some embodiments, the matrix body 22 can be a liquidized and solidifiable atomization medium made of leaves and / or stems of plants (such as tobacco), and can also be a paste-shaped atomization medium or a solid atomization medium.

[0060] In the embodiment, the thickness of the substrate body 22 can be greater than or equal to the thickness of the support body 21. Specifically, the thickness of the substrate 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 substrate body 22 on the second surface 21b of the support body 21 can be greater than the thickness of the support body 21. In other embodiments, the thickness of the substrate body 22 on the first surface 21a of the support body 21 can be equal to the thickness of the substrate body 22 on the second surface 21b of the support body 21. Understandably, in other embodiments, the thickness of the substrate body 22 on the first surface 21a of the support body 21 can also be different from the thickness of the substrate body 22 on the second surface 21b of the support body 21. In some embodiments, the taste of the substrate body 22 on the first surface 21a of the support body 21 can be the same as the taste of the substrate body 22 on the second surface 21b of the support body 21, and in other embodiments, the ingredients and taste of the two can also be different, so as to make the taste more diverse and rich. In some embodiments, the thickness of the substrate body 22 on the surface of the support body 21 can be 10-500um (including both ends), and further, the thickness of the substrate body 22 on the first surface 21a can be selected to be 100-360um (including both ends); the thickness of the substrate body 22 on the second surface 21b can be selected to be 100-360um (including both ends). Specifically, the thickness of the substrate body 22 on the first surface 21a can be 280um-300um (including both ends); the thickness of the substrate body 22 on the second surface 21b can be selected to be 280um-300um (including both ends).

[0061] In the embodiment, the thickness of the substrate body 22 in the length direction of the support body 21 is uniformly arranged. In other embodiments, the thickness of the substrate body 22 on the support body 21 can also be non-uniformly arranged, such as the thickness of some segments being greater than the thickness of other segments. In the length direction of the support body 21, the formula and taste of the substrate body 22 of different segments can be the same or different, thereby producing better roasting effect and creating a more rich taste.

[0062] In the present embodiment, the aerosol striping mode of the substrate body 22 can be selected as front atomization, that is, the surface of the substrate body 22 opposite to the second surface 21b at the first surface 21a can be used as the atomization surface. When the aerosol generating substrate 2 passes through the induction magnetic field and the support body 21 induces the electromagnetic field to heat the substrate body 22, the substrate body 22 at the first surface 21a can be opposite to the outlet position of the air channel 11, and the aerosol can be smoothly carried out by the airflow. That is, by arranging the substrate body 22 at the first surface 21a towards the outlet of the air channel 11, the aerosol generated by the substrate body 22 can be prevented from being blocked by the support body 21 and easily colliding with the wall of the box body 1 to lose kinetic energy and condense, thereby improving the aerosol carrying efficiency, increasing the aerosol amount, and ensuring the aroma.

[0063] In the present embodiment, the aerosol generating article can further include a storage structure 3 and a receiving structure 4. The storage structure 3 can be used to store the unatomized aerosol generating substrate 2, which can be a storage wheel on which the unatomized aerosol generating substrate 2 can be wound, and the aerosol generating substrate 2 can be moved through the atomization cavity 10 by unwinding and guiding of the guiding structure. The receiving structure 4 is used to receive the atomized aerosol generating substrate 2, which can be a receiving wheel on which the atomized aerosol generating substrate 2 can be wound.

[0064] By coating the substrate body 22 on both sides or multiple sides of the support body 21, the thickness of the substrate body 22 on each side can be reduced, so that the overall thickness of the aerosol generating substrate 2 is thinner, the heating is more uniform, the atomization is more sufficient, the utilization rate of the substrate body 22 is higher, the taste consistency is better, the heat of the support body 21 can be fully utilized, the energy consumption of the product is lower, and most importantly, more combinations can be achieved. For example, the thickness of the substrate body 22 on two surfaces can be different, and different flavors can be atomized and mixed at the same time to bring a different smoking experience, and the number of puffs can be increased while saving consumables.

[0065] The aerosol generating substrate 2 can realize multi-puff smoking without frequent replacement. By continuously moving the substrate body 22, fresh substrate body 22 can be replaced for each puff to realize the advantage of consistent taste for each puff. The aerosol generating substrate 2 can reduce the heat conduction path by adjusting the total thickness and distribution to achieve the purpose of sufficient baking, improving medium utilization rate and aerosol generation speed.

[0066] Fig. 6 to Fig. 9 show a second embodiment of the aerosol generating article of the present application, which differs from the first embodiment in that a plurality of through holes 211 can be provided on the support body 21. The plurality of through holes 211 can be spaced apart and each through hole 211 can be provided through the thickness direction of the support body 21. In this embodiment, the cross-sectional shape of the through hole 211 can be a regular shape, such as a circle, an ellipse, a rectangle. In some embodiments, the through hole 211 can also be selected to be a special shape, such as a gear shape, a pentagram shape, a heart shape. In other embodiments, the cross-sectional shape of the through hole 211 can also be an irregular shape, such as an irregular quadrilateral. In this embodiment, the substrate body 22 can be at least partially embedded in the support body 21, and in particular, the substrate body 22 on the first surface 21a can be partially embedded in the through hole 211 and connected with the substrate body 22 on the second surface 21b. By the plurality of through holes 211, the substrate body 22 can be surrounded on multiple sides, and thus multi-sided three-dimensional heating can be achieved, the heat conduction path is short, the heat loss is small, the heating efficiency is higher, the substrate body 22 is heated more uniformly, the release rate of active ingredients is higher, and the utilization rate of the substrate body 22 and the flavor activation effect are improved.

[0067] Fig. 10 to Fig. 11 show a third embodiment of the aerosol generating article of the present application, which differs from the first embodiment in that the support body 21 can be at least two layers, and in particular, the support body 21 can be two layers, the two layers of the support body 21 are stacked and can be fixed by the adhesive 23. The surface of the support body 21 opposite to the other layer of the support body 21 can be provided with the substrate body 22. By providing the substrate body 22 on both sides, the thickness of the substrate body 22 on each side can be thinner, so that the heating is more uniform, the atomization is more sufficient, the utilization rate of the substrate body 22 is higher, the number of puffs is improved, and the taste consistency of the generated aerosol is better.

[0068] Fig. 12 to Fig. 14 show a fourth embodiment of the aerosol generating substrate of the present application, which differs from the second embodiment in that the support body 21 as a whole can 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 can be approximately diamond-shaped, which is conducive to embedding the substrate body 22 in the non-woven fabric, thereby improving the tightness of the combination of the substrate body 22 and the support body 21, the substrate body 22 can be in a multi-sided surrounding state, and thus multi-sided three-dimensional heating can be achieved, the heat conduction path is short, the heat loss is small, the heating efficiency is higher, the substrate body 22 is heated more uniformly, the release rate of active ingredients is higher, and the utilization rate of the substrate body 22 and the flavor activation effect are improved.

[0069] In some other embodiments, the support body 21 can not be in a strip shape, but can be in a bar shape, and the cross-sectional shape thereof can be a regular shape, such as a circular shape, an elliptical shape, a rectangular shape, etc., and in some embodiments, can also be an irregular shape, such as a five-pointed star shape, a gear shape, etc. In some other embodiments, the lateral interface of the support body 21 can also be an irregular shape, such as an irregular quadrilateral shape. The support body 21 can be in a plurality of bars, and the plurality of support bodies 21 can be interlaced to form a mesh structure. Of course, it can be understood that in some other embodiments, the support bodies 21 can also be arranged in parallel at intervals, and can be fixed by a fixing member. By arranging the support bodies 21 at intervals, the substrate body 22 can be embedded in the intervals between the support bodies 21, and can wrap the support bodies 21 from multiple surfaces of the support bodies 21, thereby improving the heating uniformity and heating effect.

[0070] Figs. 15 to 16 show a fifth embodiment of the aerosol generating article of the present application, which differs from the first embodiment in that the substrate body 22 can be arranged on only one surface of the support body 21, and the support body 21 and the substrate body 22 can be wound together to form a hollow cylindrical aerosol generating substrate. The wound substrate body 22 can be located on the outer surface of the support body 21. By forming a hollow cylindrical aerosol generating substrate 2, it is advantageous to adapt to non-tape-type aerosol generating devices, and it is also advantageous to arrange the entire aerosol generating substrate 2 in a rotating manner, thereby improving the heating uniformity.

[0071] Figs. 17 to 19 show a sixth embodiment of the aerosol generating article of the present application, which differs from the fifth embodiment in that one surface of the support body 21 is provided with a plurality of protrusions 212 arranged at intervals in the length direction thereof, and the plurality of protrusions 212 can be in a bar shape and can extend in the width direction of the support body 21. The substrate body 22 is at least partially embedded in the intervals between two adjacent protrusions 212, i.e., the intervals between two adjacent protrusions 212 can be filled with the substrate body 22, i.e., the substrate body 22 can be arranged discontinuously and non-uniformly, and the taste of the substrate body 22 filled in each interval can be the same or different, thereby making the taste more diverse and rich and improving the user experience.

[0072] Figure 20 shows a seventh embodiment of the aerosol generating article of the present application, which differs from the first embodiment in that the air passage 11 is arranged opposite a side surface (a surface between the first surface 21a and the second surface 21b) of the aerosol generating substrate 2, specifically, the air passage 11 can be arranged opposite the first side surface 2a defined by the long edge and the thick edge 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 simultaneously when passing through the atomization cavity 10 and being in the U-shaped / C-shaped electromagnetic induction magnetic field, and the aerosols generated by the two can be output along the air passage 22, which will not be hindered by the support body 21, and since the air passage 11 is opposite the side surface of the aerosol generating substrate 2, the aerosol can be smoothly carried out. By selecting a suitable heating method and aerosol carrying-out method for the aerosol generating substrate 2 used, the obvious advantages of the aerosol generating substrate 2 of the present application can be maximized.

[0073] Figure 21 shows an eighth embodiment of the aerosol generating article of the present application, which differs from the seventh embodiment in that the air passage 11 is arranged opposite another side surface of the aerosol generating substrate 2, specifically, the air passage 11 can be arranged opposite the second side surface 2b defined by the wide edge and the thick edge of the aerosol generating substrate 2, which is beneficial to improve the output efficiency of the aerosol.
