Description

Technical Field

[0001] This invention relates to the field of tobacco technology, and in particular to an aerosol generating product and an aerosol generating apparatus containing the same. Background Technology

[0002] Currently, aerosol-generating products mainly include e-cigarette cartridges and heated tobacco sticks. E-cigarette cartridges have a built-in e-liquid reservoir, allowing for a relatively large number of puffs, with flavor provided by the flavorings in the e-liquid. Heated tobacco sticks contain a solid substrate that generates aerosols, with each stick supporting approximately 14 puffs. E-cigarettes, with their high e-liquid volume, allow for a large number of puffs, and the e-liquid is transported to the heating element for atomization via wicking cotton or ceramic wicking components. Insufficient e-liquid supply can lead to dry burning of the wicking cotton or ceramic wicking components, resulting in a poor vaping experience. Conventional heated tobacco sticks provide a roasted aroma, with each stick supporting more than ten puffs. For heavy smokers, this requires carrying a large number of sticks daily, making it inconvenient. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an aerosol generating product and an aerosol generating device containing the same. It uses the veins of natural plant materials to make a vein bundle conductor to conduct the aerosol generating matrix. It is not only healthy, but the vein bundle conductor can also provide a roasting aroma when heated. The user experience is close to that of cigarettes. Compared with a solid substrate, the same volume of fluid aerosol generating matrix can provide more puffs.

[0004] The technical solution provided by this invention is as follows: An aerosol generating product includes a shell, a fluid aerosol generating matrix, and a vein bundle guide. A liquid channel exists between the fluid aerosol generating matrix and the vein bundle guide to allow the vein bundle guide to guide and store the fluid aerosol generating matrix. The fluid aerosol generating matrix and the vein bundle guide are disposed within the shell. The vein bundle guide includes a plurality of plant veins.

[0005] Preferably, the pulse beam guide includes a first drainage path and a second drainage path that are interconnected. The first drainage path is a liquid transport path formed by several intervening spaces of plant veins and the surface of plant veins. The second drainage path is the fluid transport path formed by the internal vessels of each plant vein.

[0006] Preferably, the plant veins are obtained from at least one natural plant leaf through a milling process. The vein bundle conductor preserves the original plant veins, and several plant veins form a vein bundle matrix through orderly arrangement or disordered superposition. The pulse beam conductor is made by cutting and processing a pulse beam matrix.

[0007] Preferably, the natural plant leaves include one or more combinations of leaves from the genera *Tobacco*, *Camellia*, or other nicotine-rich plants.

[0008] Preferably, when the natural plant leaf is a tobacco leaf, the tobacco leaf is at least one of Burley tobacco, Maryland tobacco, and Oriental tobacco; When extracting leaf veins from tobacco leaves, some leaf mesophyll tissue is retained, with the mesophyll tissue content accounting for 1% to 10%.

[0009] Preferably, the fluid aerosol generating matrix comprises tobacco extract.

[0010] Preferably, the fluid aerosol generating matrix further includes a hot-melt packaging material, in which the tobacco extract is encapsulated.

[0011] Preferably, the shape of the outer shell is not limited. It can be shaped like a cartridge for an electronic cigarette, a cigarette stick for a heated tobacco product, or a capsule. The outer shell is preferably rod-shaped or fish-mouth-shaped, and includes a suction end and an atomizing end. Both the fluid aerosol generating matrix and the pulse beam guide are located at the atomizing end.

[0012] Preferably, the above-mentioned aerosol generating product further includes a heating element, and the pulse beam conductor is located around the heating element and conducts heat directly or indirectly with the heating element.

[0013] Preferably, the heating element is one of resistive heating, infrared heating, or magnetic induction heating.

[0014] An aerosol generating apparatus includes the aforementioned aerosol generating product and a power supply unit. The power supply unit includes a heating element. When the aerosol generating product and the power supply unit are used together, the heating element and a fluid aerosol generating matrix guided to the vicinity of the heating element through a pulse beam guide undergo heat transfer to generate aerosols.

[0015] An aerosol generating device includes the aforementioned aerosol generating product and an energy supply unit. The energy supply unit is configured in conjunction with a heating element to provide energy to the heating element. The heating element and a fluid aerosol generating matrix guided by the pulse bundle conductor to the vicinity of the heating element undergo heat transfer to generate aerosol.

[0016] The present invention has the following advantages over the prior art: 1. Compared to atomized electronic cigarettes, the aerosol generating product of the present invention uses the veins of natural plant materials to make a pulse bundle conductor to conduct the aerosol generating matrix. It is not only healthy, but the pulse bundle conductor can also provide a roasting aroma when heated, and the user experience is close to that of cigarettes.

[0017] 2. Compared with heated non-combustible cigarettes, the aerosol generating product of the present invention can provide more puffs for the same volume of fluid aerosol generating matrix compared with solid substrate.

[0018] 3. In the aerosol-generated product of the present invention, when the raw material for making the vein bundle guide is tobacco leaf, the leaf mesophyll tissue peeled from the vein of the tobacco leaf can be used to extract tobacco extract, thereby improving the utilization rate of tobacco raw materials; when the raw material for making the vein bundle guide is not tobacco leaf, the veins of other plants can also be used to make the vein bundle guide, and the flavor of other plants can also be added to the aerosol-generated product.

[0022] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] Example 1: like Figure 1-3 As shown, this embodiment of the invention provides an aerosol generating product, including a shell 1, a fluid aerosol generating matrix 2, a pulse bundle guide 3, and a heating element 4. A liquid channel exists between the fluid aerosol generating matrix 2 and the pulse bundle guide 3 (the fluid aerosol generating matrix 2 and the pulse bundle guide 3 can be directly connected (the liquid channel is the contact surface between the two) or indirectly connected through the liquid channel) so that the pulse bundle guide 3 can guide and store the fluid aerosol generating matrix 2. The fluid aerosol generating matrix 2 and the pulse bundle guide 3 are disposed within the shell 1. The pulse bundle guide 3 includes several plant veins. Plant veins refer to the vascular tissue left after removing the epidermis and mesophyll tissue from plant leaves. The pulse bundle guide is used for the conduction of the aerosol generating matrix, which can not only replace oil-absorbing cotton or microporous ceramics, making it healthier for the human body, but also provide a roasting aroma when heated.

[0024] In this embodiment, the plant veins are obtained from at least one natural plant leaf through a grinding process. The vein bundle guide retains the original plant veins, and the plant mucus on the original veins acts as a natural adhesive. The mucus is fully utilized to form a vein bundle matrix through orderly arrangement or disordered stacking of the original veins. The vein bundle matrix can be in the form of thin strips or blocks. The vein bundle guide 3 is processed from the vein bundle matrix, for example, a cylindrical vein bundle guide 3 formed by winding thin sheets, or a cylindrical or irregularly shaped vein bundle guide 3 obtained by cutting blocks. The plant vascular bundles in the vein bundle matrix not only have their internal structures as natural transport channels, but the surface of the veins also serves as transmission lines, enabling the guidance of fluid aerosol generation matrix. Simultaneously, the leaf vein patterns of plants vary, with veins gradually changing from thick to thin from the leaf diameter to the leaf tip. The thick veins are spaced far apart, while the thin veins are spaced far apart. The vascular bundle matrix forms a network of veins, which not only has a guiding function but also a flow storage function. A schematic diagram of the plant veins is shown below. Figure 2 As shown. Because the pulse bundle guide 3 is composed of natural plants, when the heating element 4 heats the fluid aerosol generating matrix 2, it also heats the pulse bundle guide 3, generating a second type of aerosol (the fluid aerosol generating matrix 2 produces the first type of aerosol when heated). This second type of aerosol provides the roasted aroma of the plants. Compared with traditional atomized electronic cigarettes, the pulse bundle guide 3 replaces wicking cotton or microporous ceramics, making it not only healthier but also providing a more natural flavor. When the natural plant leaves are tobacco leaves, it can provide the aroma of tobacco.

[0025] In this embodiment, the natural plant leaves include one or more combinations of leaves from plants of the *Tobacco*, *Camellia*, or other nicotine-rich species. Tobacco leaves are preferred as the natural plant leaves. When tobacco leaves are used, they are at least one of Burley tobacco, Maryland tobacco, or Oriental tobacco. When extracting veins from tobacco leaves, a portion of the leaf mesophyll is retained, with the mesophyll content ranging from 1% to 10%. The nicotine content in the mesophyll is higher than that in the vein tissue, and the vein bundle can provide a richer tobacco aroma.

[0026] In this embodiment, the fluid aerosol generating matrix 2 includes tobacco extract and is either semi-solid or liquid. When the fluid aerosol generating matrix 2 is semi-solid, it gradually becomes liquid as the temperature rises. The liquid fluid aerosol generating matrix 2 is transported to the heating element along the structure of the pulse bundle guide 3. The heating element 4 comes into thermal contact with the liquid fluid aerosol generating matrix 2. After reaching the atomization temperature, the fluid aerosol generating matrix 2 generates the first aerosol, which provides the vapor volume and flavor experience. Common liquid fluid aerosol generating matrix 2 is e-liquid. The semi-solid fluid aerosol generating matrix 2 contains reversible thickeners, such as gelatin, gum arabic, and other natural substances with polysaccharides and proteins in their molecular structure. At room temperature, it thickens through molecular entanglement or colloidal particle aggregation. As the temperature rises, the molecules denature or the structure disperses, reducing the viscosity. This process is safe and reversible with temperature variations.

[0027] The aerosol generated in this embodiment produces an aerosol containing a first type of aerosol and a second type of aerosol. It can support a large number of puffs and has a roasted aroma, providing not only a better product experience but also convenience for users to carry when going out.

[0028] In this embodiment, the fluid aerosol generating matrix 2 also includes a hot-melt packaging material. The tobacco extract is encapsulated inside the hot-melt packaging material, reducing the contact time between the tobacco extract and the pulse bundle guide, preventing the tobacco extract from accumulating at the bottom of the cigarette, and also reducing the volatilization of the tobacco extract during transportation. Under the influence of the heat from the heating element 4, when the temperature around the fluid aerosol generating matrix 2 rises to the desired temperature, the hot-melt packaging material melts, and the tobacco extract flows to the pulse bundle guide 3. The ideal melting temperature of the hot-melt packaging material is 60-100 degrees Celsius. The hot-melt packaging material can be selected from polysaccharides (modified starch, alginate), proteins (whey protein, soy protein), and lipid complexes (beeswax + polysaccharide / protein).

[0029] In this embodiment, a perforated packaging material can be made using a pulse bundle matrix. The porosity of the pulse bundle matrix is ​​controlled to within 15% under high pressure, resulting in low liquid permeability. The pores of the packaging material are sealed with hot melt packaging material. When the temperature around the fluid aerosol generating matrix 2 rises to the desired temperature, only the hot melt packaging material sealing the pores melts, reducing the impact of protein-based hot melt materials on the flavor of the aerosol.

[0030] In this embodiment, the outer shell 1 is rod-shaped and includes a suction end 11 and an atomizing end 12 in sequence. The atomizing end 11 is relative to the suction end. The atomizing end 12 is not necessarily at the bottom of the aerosol generating product, but can also be in the middle. The fluid aerosol generating matrix 2 and the pulse bundle guide 3 are both disposed at the atomizing end 12.

[0031] In this embodiment, the pulse bundle guide 3 is located around the heating element 4 and conducts heat directly or indirectly with the heating element 4. The heating element 4 can be tubular, sheet-like, or columnar, and is placed horizontally or vertically relative to the bottom of the fluid aerosol generating matrix 2. The pulse bundle guide 3 conducts heat directly or indirectly with the heating element 4 around it. The fluid aerosol generating matrix 2 is located at least one position above, below, or around the pulse bundle guide 3, and can also fill the pulse bundle guide 3. Using the pulse bundle guide 3 to conduct and transport the fluid aerosol generating matrix 2 is healthier than traditional atomized electronic cigarettes. The plant-based properties of the pulse bundle guide 3 enable it to release an aerosol with a roasted aroma when heated. Compared to traditional atomized electronic cigarettes, the aerosol generated by the present application produces an aerosol flavor closer to traditional cigarettes, resulting in a better user experience. In addition, the fluid aerosol generating matrix 2 can provide more inhalation ports, making it easy to carry.

[0032] In this embodiment, the vein bundle guide 3 is tubular, with an inner cavity 5 accommodating the insertion of the heating element 4. A fluid aerosol generating matrix 2 surrounds the outer circumference of the vein bundle guide 3. After the heating element 4 heats up, it heats the fluid aerosol generating matrix 2 guided by the vein bundle guide 3, generating aerosols. The top or bottom of the cavity of the vein bundle guide 3 can also be sealed with the vein bundle matrix, which is composed of plant veins with gaps in the middle to allow airflow and enhance the roasting aroma.

[0033] Preferably, the heating element 4 is one of resistive heating, infrared heating, or magnetic induction heating.

[0034] An aerosol generating device includes the aforementioned aerosol generating product. When the heating element 4 in the aerosol generating product is a resistive heating element, the aerosol generating device is provided with an electrical connection interface. The heating element 4 forms a circuit with the circuit in the aerosol generating device through the electrical connection interface. When the aerosol generating device is powered, the heating element 4 is heated to a temperature between 200 degrees Celsius and 400 degrees Celsius. When the heating element 4 in the aerosol generating product is an induction heating element, the aerosol generating device includes a cavity for accommodating the aerosol generating product and an inductor that generates a fluctuating electromagnetic field within the cavity. When the aerosol generating product is placed in the cavity, a changing magnetic field is generated within the cavity when the aerosol generating device is powered. The heating element 4 in the aerosol generating product heats up in the changing magnetic field to a temperature between 200 degrees Celsius and 400 degrees Celsius, at which point the aerosol generating product generates aerosol.

[0035] Example 2: like Figure 4 , 5 As shown, the difference between this embodiment and Embodiment 1 is that the aerosol generating product does not contain a heating element 4. The aerosol generating product of this embodiment is used in conjunction with an aerosol generating device. The aerosol generating device is equipped with a heating element 4. During use, the heating element 4 and the pulse bundle guide directly or indirectly conduct heat to generate aerosol. In addition, the pulse bundle guide 3 of this embodiment is a W-shaped hollow component. The hollow cavity 5 accommodates the insertion of the heating element 4. The bottom of the pulse bundle guide 3 extends to contact the bottom and side wall of the shell 1. Each side of the cavity is U-shaped, and the fluid aerosol generating matrix 2 is placed in the U-shaped concave part. The outer shell 1 of this embodiment is fish-mouth shaped.

[0036] Example 3: like Figure 6 As shown, the difference between this embodiment and embodiment 2 is that the pulse bundle guide 3 in this embodiment is tubular, with its outer circumference in contact with the inner wall of the shell 3, and the inner cavity 5 of the tube accommodating the insertion of the heating element 4. The fluid aerosol generating matrix 2 is in contact with the side of the pulse bundle guide 3 near the mouthpiece section. When smoking a cigarette, the aerosol can be carried out by the air passing around the heating element 4 / through the pulse bundle guide 3.

[0037] Example 4: like Figure 7 As shown, the difference between this embodiment and embodiment 2 is that the outer circumferential surface of the pulse beam guide 3 in this embodiment is in contact with the inner wall of the outer shell 1, the heating element 4 surrounds the outside of the aerosol generating product, and the part of the pulse beam guide 3 in contact with the cigarette stick. The pulse beam guide 3 guides the fluid aerosol generating matrix 2 to the direction of the heating element for atomization, and the fluid aerosol generating matrix 2 is in contact with the side of the pulse beam guide 3 near the mouthpiece section.

[0038] Example 5: like Figure 8As shown, the difference between this embodiment and embodiment 4 is that the pulse bundle guide 3 is U-shaped, and the fluid aerosol generating matrix 2 is placed in the concave part of the U-shape.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
