Description

An aerosol generating article TECHNICAL FIELD

[0001] The present application belongs to the technical field of aerosol, and particularly relates to an aerosol generating article. BACKGROUND

[0002] Heat-not-burn tobacco products are a kind of products that release an inhalable aerosol product containing nicotine or other specific components by volatilizing, distilling and slightly pyrolyzing solid tobacco materials at the ignition temperature of the tobacco rod material through an external heat source. Since the design avoids the combustion of tobacco materials, the known toxic and harmful substances contained in the aerosol formed are significantly reduced compared with cigarette smoke. At present, there are various commercial and patented heat-not-burn tobacco products with electric heating and carbon heating as heat sources.

[0003] Electrically heated heat-not-burn tobacco products (electrically heated cigarettes) use a rechargeable heat source, are convenient to use, and the heating temperature curve can be adjusted. However, the one-time purchase cost of the heating appliance is relatively high, and the frequent iteration of the appliance further increases the economic burden of the user and the social environmental burden. In addition, there are problems such as long preheating waiting time of the tobacco rod, timely charging of the appliance, etc., which affect the user's consumption experience.

[0004] Carbon-heated heat-not-burn tobacco products (carbon-heated cigarettes) are heat sources formed by extruding powdered carbon materials, and the carbon heat source is solidified on the tobacco rod structure through a tobacco rod production composite process. When using carbon-heated cigarettes, the carbon heat source is introduced into a combustion state in a way similar to lighting a cigarette, and along with the user's suction action, external airflow is first heated to a high temperature by the carbon heat source, and then flows through the solid tobacco part. The tobacco material undergoes thermal physical and thermochemical reactions caused by radiation heat conduction from the carbon heat source and secondary heat transfer brought by hot gas flow, forming an inhalable aerosol. This way maximizes the simulation of the use mode of combustible cigarettes, and has higher use convenience than electric heating, but the disadvantage is that the processing and manufacturing process of the tobacco rod is complex, which brings high manufacturing cost, and is not conducive to the large-scale commercial development of such heat-not-burn tobacco products.

[0005] In order to solve the above problems, the present application is proposed. SUMMARY

In use, the user assembles the heating source and the matching heating consumable into a disposable heating product, and ignites the heating source to atomize the aerosol generating substrate in the heating consumable.

[0007] The disposable ignition type heating source proposed in the present application can use carbon powder or other biomass or chemical oxidizing agent or smoldering agent alone or in combination, and form a structure connected with and sealed with a heating consumable. The heat source has the advantages of simple structure, convenient manufacturing process, no need for electric heating appliance or charging equipment, and can be matched with various existing heating cigarettes for use, etc., greatly facilitating the conversion of consumers to heating non-combustion tobacco products.

[0059] As shown in FIGS. 1-2, an aerosol generating article includes a heat source connecting portion 1 and an aerosol generating portion 2.

[0060] The heat source connecting part 1 comprises a heat source part 1-1 and a connecting part 1-2.

[0061] The heat source connecting part 1 is configured to be detachably connected with the aerosol generating part 2 through the connecting part 1-2 or the heat source connecting part 1 and the aerosol generating part 2 are separately arranged; the heat source connecting part 1 and the aerosol generating part 2 are in airflow communication.

[0062] Preferably, the heat source connecting part 1 is provided with a cavity 1-3 downstream of the heat source part 1-1.

[0063] Of course, the cavity 1-3 described above can not be provided. In this case, the heat source part 1-1 and the aerosol generating part 2 need to be separated by a heat-resistant and fire-resistant component to avoid the heat source part 1-1 igniting the aerosol generating part 2. For example, an aluminum foil layer with holes is arranged downstream of the heat source part, which can transfer hot airflow or conduct heat while separating the heat source part 1-1 and the aerosol generating part 2.

[0064] The aerosol forming heating principle of the present application is to use an external heat source such as a match or a lighter to ignite the heat source part 1-1 in the present application to form a primary smoldering heat source. When smoking, the airflow flowing through the primary smoldering heat source and the aerosol generating part 2 is heated, and the hot airflow heats the tobacco carrier or the atomizing agent part of the aerosol generating part 2 when flowing through them, so that the components in the aerosol generating part 2 such as tobacco and / or atomizing agent materials are released and migrated by heat to form an inhalable aerosol. The tobacco carrier can contain tobacco or non-tobacco aerosol releasing substances.

[0065] The heat source part 1-1 contains a disposable combustion heat source material. The disposable combustion heat source material can be a material that can be ignited and then maintained in a smoldering state. The heat source material is preferably carbon powder or granular carbon material, and other biomass materials or chemical reaction heat energy releasing materials with similar characteristics to carbon material heat source or a combination of these materials can also be used. The heat source material can be ignited by a common heat source such as a match or a lighter during smoking. During the heat energy release process, the heat source material gradually completes its combustion and oxidation reaction to release heat energy. The amount of heat energy released can fluctuate with the entry of the smoking airflow. The heat source material needs to meet the following requirements: the combustion products formed should not contain other unacceptable organic substances with inhalation toxicological characteristics in addition to the oxides of organic and inorganic elements such as carbon and nitrogen. The heat source part 1-1 can be formed by all or part of extrusion, adhesion, granular molding, 3D printing, filling, and similar molding or combined processes. The appearance of the heat source part 1-1 can be cylindrical, long strip-shaped or other shapes, or a combination of the above shapes, to facilitate heat exchange when the smoking airflow flows through. As shown in FIG. 1-7, the heat source part 1-1 is cylindrical.

[0066] In a preferred technical solution, the mass of the heat source material and the molding process are combined to enable the heat source material to maintain a stable smoldering state for a period of time, such as 3-5 minutes, after being ignited by a lighter or match, to fully adapt to the use requirements of the heat-not-burn aerosol generating product, i.e., the aerosol generating portion 2.

[0067] Preferably, the heat source portion 1-1 has airflow conduction holes 1-1-1 therein. As shown in FIG. 3, the number of airflow conduction holes 1-1-1 is one or more. The airflow conduction holes 1-1-1 pass through the heat source portion 1-1. The airflow conduction holes 1-1-1 can be naturally formed or processed and molded. More preferably, as shown in FIG. 2, one end of the airflow conduction holes 1-1-1 is exposed to the external environment, and the other end is connected to the cavity 1-3 downstream of the heat source portion 1-1. The through airflow conduction holes 1-1-1 allow the suction airflow to be effectively heated by directly or indirectly flowing through the ignited heat source material, and form a comfortable suction pressure drop with the aerosol generating portion 2 during use. The shape of the airflow conduction holes 1-1-1 can be linear, zigzag, or curved.

[0068] The airflow conduction holes 1-1-1 can be formed by naturally or processing or molding the heat source portion 1-1 filled with a filler having single or multiple holes. The filler can be distributed uniformly or non-uniformly in the cross-section of the heat source portion 1-1. By controlling the filling density and filling area of the filler, on the one hand, the heating efficiency of the airflow can be increased, and on the other hand, various tortuosity airflow channels, such as S-shaped, can be introduced to increase the residence time of the suction airflow and adjust the suction airflow temperature to achieve the designed downstream heating efficiency. The filler can be selected from porous biomass, ceramic, glass, or metal or their combination particles, etc.

[0069] The heat source portion 1-1 can contain combustion-supporting agents or oxidizing agents to assist the maximum and controllable release of heat energy, ensuring that it maintains a smoldering state during ignition and suction. In addition, targeted catalysts can also be added as needed to help the maximum oxidation of the biomass material therein, such as to minimize the amount of inhaled carbon monoxide generated during suction.

[0070] The molded heat source material is embedded or bonded as part of or all of the heat source portion 1-1 into the cavity of the connecting portion 1-2. The material of the connecting portion 1-2 is any natural or synthetic biomass, natural or synthetic fiber material, various types of glass, metal, composite material. Plant materials or plant-derived structural fibers are preferred, and the preferred source is renewable, directly or after industrial processing, environmentally friendly and biodegradable biomass and organic materials.

[0071] Preferably, the downstream portion of the heat source portion 1-1 is located in the connecting portion 1-2, and the upstream portion is exposed outside the connecting portion 1-2.

[0072] As shown in Fig. 4, preferably, the connecting section 1-2 is provided with an inner lining 1-4. The inner lining 1-4 can be a fire-resistant inner lining provided around the heat source section 1-1. The fire-resistant inner lining is used to increase the air-tightness and the strength of the composite structure connecting with the heat source section 1-1. Meanwhile, the fire-resistant inner lining ensures that the heat source material does not ignite the cavity material during use. The fire-resistant inner lining includes high-heat-resistant synthetic materials, synthetic fibers, metals, ceramics, and other fire-resistant materials with high thermal stability. The materials of the connecting section 1-2 and the fire-resistant inner lining should not release substances that can significantly negatively affect the inhalation aerosol toxicology characteristics when heated during the heat release operation of the heat source.

[0073] The inner lining 1-4 can also be a heat-conductive inner lining provided around the heat source section 1-1. The heat-conductive inner lining is used to increase the air-tightness and the strength of the structure connecting with the heat source material, while allowing the heat of the front heat source section 1-1 to be transmitted to the aerosol generating section 2 through the heat-conductive inner lining, forming a certain degree of circumferential heating.

[0074] Preferably, the material of the connecting section 1-2 can have heat conductivity, and appropriately heat the inserted aerosol generating section 2 during use, to assist the formation of internal aerosol.

[0075] The material of the connecting section 1-2 can consider internal additional metal or ceramic heat-conductive materials, and external natural or synthetic biomass such as wood. The increased metal or ceramic heat conduction can further assist the downstream aerosol release and conduction. For example, the inner layer of the connecting section 1-2 is a metal layer or a ceramic layer, and the outer layer is a wood layer.

[0076] The connecting section 1-2 is preferably a tubular structure.

[0077] The interface of the connecting section 1-2 with the insertion end of the aerosol generating section 2 needs to facilitate the user to insert the aerosol generating section 2, while ensuring the air-tightness of the overall structure during ignition and suction after insertion.

[0078] Three possible implementations are given in Fig. 5, which are not limited to the implementations:

[0079] Method 1: The downstream section of the connecting section 1-2 is an inner diameter expansion section. The inner diameter expansion section can be formed by providing a circumferential inner recess in the connecting section 1-2. The depth and width of the circumferential inner recess can be used to control the depth of insertion. The inner diameter expansion section can be provided in one section or multiple sections, for example, in multiple stepped layers, to match aerosol generating sections 2 of different diameters.

[0080] Method 2: The downstream section of the connecting section 1-2 is an inner diameter gradually expanding section, allowing the depth of insertion of the aerosol generating section 2 to have a certain adjustability. The inner diameter gradually expanding section gradually expands in diameter from upstream to downstream.

[0081] Way 3: The inner wall of the downstream section of the connecting part 1-2 is provided with a section of internal thread structure, allowing the aerosol generating part 2 to be inserted in a tight fit.

[0082] The combination of the heat source part 1-1, the connecting part 1-2 and the aerosol generating part 2 structure, on the one hand, needs to give the user a clear design insertion depth, and on the other hand, can allow the user to adjust the length of the cavity 1-3 according to the needs after insertion, bringing different heating effects and sensory experiences. The connecting part 1-2 is configured to adjust the volume of the cavity 1-3 after the aerosol generating part 2 is inserted to different depths, but the volume of the cavity 1-3 is not zero. The axial size of the cavity 1-3 should ensure that the insertion end of the aerosol generating part 2 is not ignited by the heat source during use, ensuring the heating and atomization state.

[0083] In addition, without affecting the suction airflow, the connecting part 1-2 can also optimize the structure of the cavity 1-3 or add functional materials to optimize the release characteristics of the inhalable aerosol, and assist in improving the sensory experience of the user during smoking.

[0084] Preferably, the cavity 1-3 is provided with a functional material part. The functional material part contains functional materials. The functional materials can be porous adsorbents or taste adjusters, and can also be inhalable solvents that assist in aerosol formation. The functional materials are released during the insertion of the aerosol generating part 2 and supplement the instant atomization agent of the aerosol generating part 2, thereby enriching and improving the inhalation experience.

[0085] The added functional materials can be a combination of one or more materials and forms such as particles, high-transparency membranes, porous media, capsules, etc. The following Figure 6 shows three possible implementation ways of adding functional material cavities, and the loaded components are migrated from the functional material to the aerosol generating part 2 or the airflow by the hot airflow.

[0086] In Figure 6: Way 1 - the functional material part is a porous membrane, and the membrane material can be a functional material loaded with aroma components; Way 2 - the functional material part is a fragrance-loaded particle, and the particle can preferentially select a large pore structure, and the particle surface or interior can load aroma components; Way 3 - the functional material part is a capsule, and the capsule coating can be made of heat-sensitive material, and the interior is wrapped with aroma components.

[0087] Preferably, the cavity 1-3 can increase the connecting part 1-5 abutting between the heat source part 1-1 and the aerosol generating part 2. The connecting part 1-5 is preferably a heat-conducting connecting part, and its material is a heat-conducting material. The heat of the front heat source part 1-1 can be transferred to the surface of the aerosol generating substrate part 2-1 of the aerosol generating part 2 through the heat-conducting connecting part 1-5. Figure 7 shows two representative designs of the connecting part 1-5, Way 1 - column structure; Way 2 - "T" structure, one end of the larger end face of the "T" structure abuts the heat source part 1-1, and this structure can increase the contact area of the connecting part 1-5 with the heat source part 1-1, and strengthen the heat conduction.

[0088] Preferably, one end of the larger end face of the "T" structure is a porous end face, which allows for effective heat transfer. Furthermore, one or more axial airflow channels can be incorporated within both the columnar and "T" structure bodies to enhance heat dissipation.

[0089] Of course, one end of the larger end face of the “T” structure can also abut against the aerosol generation matrix 2-1 to achieve uniform heat distribution in the aerosol generation matrix 2-1.

[0090] Alternatively, an "I"-shaped connector 1-5 can be provided. The two larger end faces of the "I"-shaped structure abut against the heat source part 1-1 and the aerosol generating part 2, respectively.

[0091] Preferably, the heat source connection portion 1 includes an extension portion 1-6 connected to the heat source portion 1-1 and extending into the cavity 1-3. As shown in FIG8, one end of the extension portion 1-6 is connected to the heat source portion 1-1, and the other end has a certain length exposed in the cavity 1-3. The extension portion 1-6 can serve as a heat conduction component, a piercing component, or a reinforcement component. The extension portion 1-6 can be a heat transfer component, a piercing component, or a structural reinforcement component, with the specific structure as follows:

[0092] Preferably, the heat source section 1-1 and the heat transfer component form an integral structure within the connecting section 1-2. The heat transfer component is composed of needles, plates, or rods made of metal or other thermally conductive materials, and may also be a heat pipe with high heat transfer characteristics. One end of the heat transfer component is connected to the heat source material, and the other end has a certain length exposed in the cavity 1-3. When the aerosol generating section 2 is inserted into the cavity 1-3, the other end of the heat transfer component, i.e., the exposed end, is inserted into its interior, playing an auxiliary or primary central heating function in the heat generation process of the heat source material, helping the formation and release of aerosols. See Figure 9.

[0093] Preferably, the heat source 1-1 and the puncturing component form an integral structure within the connecting part 1-2. The puncturing component can be needle-shaped, sheet-shaped, or rod-shaped. One end of the puncturing component is connected to the heat source material, and the other end has a certain length exposed in the cavity 1-3. When the aerosol generating part 2 is inserted into the cavity 1-3, the exposed end of the puncturing component is inserted into the interior of the aerosol generating part 2, serving to break or crush objects that can be crushed or shattered. The crushable or shatterable objects can be capsules or contactless substances containing liquid, solid, colloidal slow-release flavoring substances or substances that can form aerosols. When the user inhales the aerosol generating part 2, part or all of it is converted into inhalable aerosol. See Figure 10.

[0094] Preferably, the heat source portion 1-1 and the structural reinforcement member form an integrated structure inside the connecting portion 1-2. The structural reinforcement member can be needle-shaped, sheet-shaped or rod-shaped. One end of the structural reinforcement member is connected to the heat source material, and the other end has a certain length exposed in the cavity 1-3. When the aerosol generating portion is inserted into the cavity 1-3, the exposed end of the structural reinforcement member is inserted into the inside of the aerosol generating portion 2, and functions to reinforce the aerosol generating portion 2 and the heat source portion 1-1. As shown in FIG. 11.
