Description

Technical Field

[0001] The utility model belongs to the technical field of aerosols, and in particular relates to an aerosol generating product. Background Art

[0002] Heated cigarettes are products that release inhalable aerosols containing nicotine or other specific ingredients by volatilizing, distilling and lightly pyrolyzing solid tobacco materials at the ignition temperature of the cigarette material through an external heat source. Since the combustion of tobacco materials is avoided in its design, the known toxic and harmful substances of tobacco contained in the formed aerosol are significantly lower than those in cigarette smoke. Currently, there are many commercial and patented heat-not-burn tobacco products that use 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 easy to use, and have an adjustable heating temperature curve. However, the one-time purchase cost of the heating device is high, and the frequent iteration of the device further increases the economic burden on users and increases the social and environmental burden. In addition, there are problems such as the long waiting time for preheating cigarettes and timely charging of the device during use, which affect the user's consumption experience.

[0004] Carbon-heated heat-not-burn tobacco products (carbon-heated cigarettes) are heat sources that extrude powdered carbon materials and solidify the carbon heat source on the cigarette structure through a composite cigarette production process. When using carbon-heated cigarettes, the carbon heat source is introduced into a combustion state in a manner similar to that of lighting a cigarette. As the user draws, the external airflow first passes through the carbon heat source and is heated to a high temperature, and then flows through the solid tobacco portion. The tobacco material undergoes thermophysical and thermochemical reactions caused by the radiation heat conduction of the carbon heat source and the secondary heat transfer brought about by the hot air flow, forming an inhalable aerosol. This method imitates the usage pattern of combustible cigarettes to the greatest extent possible and is more convenient to use than electric heating, but the disadvantage is that the processing and manufacturing process of the cigarette is complicated, which results in a higher manufacturing cost, which 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 utility model is proposed. Utility Model Content

[0006] The present application proposes a heat-not-burn aerosol atomization product with a separate design of a burning heating source and a matching consumable.

[0007] The disposable ignition type heating source proposed in the present application can use carbon powder or other biomass or chemical oxidant or smoldering agent alone or in combination, and form a closed structure connected to the heating consumable.

[0064] like Figure 1-2 , an aerosol generating product, the aerosol generating product comprising: a heat source connecting part 1 and an aerosol generating part 2;

[0065] Wherein, the heat source connecting part 1 comprises: a heat source part 1-1 and a connecting part 1-2;

[0066] The heat source connection part 1 is configured to be detachably connected to the aerosol generating part 2 through the connection part 1-2 or the heat source connection part 1 and the aerosol generating part 2 are separately arranged;

[0067] The heat source connection part 1 and the aerosol generation part 2 are connected by airflow.

[0068] Preferably, a cavity 1 - 3 located downstream of the heat source portion 1 - 1 is provided in the heat source connection portion 1 .

[0069] Of course, the cavity 1-3 may not be provided. In this case, the heat source 1-1 and the aerosol generating part 2 need to be separated by a heat-resistant and flame-retardant component to prevent the heat source 1-1 from igniting the aerosol generating part 2. For example, a perforated aluminum foil layer is provided downstream of the heat source. The aluminum foil layer can separate the heat source 1-1 and the aerosol generating part 2 while transmitting hot air flow or conducting heat.

[0070] The aerosol forming heating principle of the present application is that the user ignites the heat source part 1-1 in the utility model with an external fire source, such as a match or a lighter, to form a primary smoldering heat source. When inhaling, 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 atomizer part of the aerosol generating part 2 when flowing through it, so that the components such as tobacco and / or atomizer materials in the aerosol generating part 2 are released and migrated by heat to form an inhalable aerosol. The tobacco carrier can contain tobacco or non-tobacco aerosol releasing substances.

[0071] The heat source part 1-1 contains a disposable combustion heat source material. The disposable combustion heat source material is a material that can maintain a smoldering state after being ignited. The heat source material is preferably carbon powder or granular carbon material. Other biomass materials or chemical reaction heat energy releasing materials with heat source characteristics similar to carbon materials, or a combination of these materials can also be used. The heat source material can be ignited by common fire sources during suction, such as matches and lighters. During the heat energy release process, the heat source material gradually completes its combustion and oxidation reactions to release heat energy. The amount of heat energy released may fluctuate with the entry of the suction airflow. The heat source material needs to meet the following requirements: the combustion products formed should not contain other unacceptable organic substances with inhalation toxicity characteristics except for oxides of organic and inorganic elements such as carbon and nitrogen. The molding of the heat source part 1-1 can be manufactured by all or part of extrusion, bonding, particle molding, 3D printing, filling and other similar molding or combined processes. The appearance of the heat source part 1-1 can be cylindrical, elongated or other shapes, or a composite of the above shapes, to facilitate heat exchange when the suction airflow flows through. Such as Figure 1-7 In the figure, the heat source part 1-1 is cylindrical.

[0072] In the preferred technical solution, the quality of the heat source material and the molding process are combined so that the heat source material can stably smolder for an adapted time period, such as 3-5 minutes, after being ignited by a lighter or a match, fully meeting the use requirements of the heat-not-burn atomization product, namely the aerosol generating part 2.

[0073] Preferably, the heat source portion 1-1 has an air flow conducting hole 1-1-1. Figure 3 As shown, the number of the airflow conduction holes 1-1-1 is one or more. The airflow conduction holes 1-1-1 penetrate the heat source part 1-1. The airflow conduction holes 1-1-1 can be processed or naturally formed. More preferably, as Figure 2 One end of the airflow conduction hole 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 part 1-1. The airflow conduction hole 1-1-1 that penetrates in this way allows the inhalation airflow to flow directly or indirectly through the ignited heat source material to be effectively heated, and forms a comfortable inhalation pressure drop with the aerosol generating part 2 when in use. The shape of the airflow conduction hole 1-1-1 can be straight, broken line or curved.

[0074] The airflow conduction holes 1-1-1 can be formed by filling the heat source part 1-1 with a single-hole or multi-hole filler naturally or by processing or molding. The filler can be geometrically uniformly or non-uniformly distributed on the cross section of the heat source part 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, airflow channels with various tortuosity, such as S-shape, 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, ceramics, glass or metal or their combined particles.

[0075] The heat source part 1-1 may contain a combustion aid or an oxidant to assist in the maximum and controllable release of heat energy, so as to ensure that it remains in a smoldering state during the ignition and suction process. In addition, a targeted catalyst may be added as needed to help maximize the oxidation of the biomass material therein, for example, to minimize the amount of carbon monoxide that can be inhaled during the suction process.

[0076] The formed heat source material is embedded or bonded into the cavity of the connecting part 1-2 as part or all of the heat source part 1-1. The material of the connecting part 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 renewable, direct or industrially processed, environmentally friendly and degradable biomass and organic materials are preferred.

[0077] Preferably, the downstream portion of the heat source part 1 - 1 is located inside the connecting part 1 - 2 , and the upstream portion is exposed outside the connecting part 1 - 2 .

[0078] like Figure 4 Preferably, an inner lining layer 1-4 is provided in the connecting portion 1-2. The inner lining layer 1-4 may be a flame retardant inner lining layer provided on the periphery of the heat source portion 1-1. The flame retardant inner lining layer is used to increase the air tightness and composite structural strength of the connection with the heat source portion 1-1. At the same time, the flame retardant inner lining layer ensures that the heat source material does not ignite the cavity material during use. The flame retardant inner lining layer includes highly heat-resistant synthetic materials, synthetic fibers, metals, ceramics and other flame retardant materials with high thermal stability. When the heat source is working in an exothermic manner, the materials of the connecting portion 1-2 and the flame retardant inner lining layer should not be heated to release substances that may significantly negatively affect the toxicological properties of the inhaled aerosol.

[0079] The inner lining layer 1-4 may also be a heat conductive inner lining layer provided on the periphery of the heat source part 1-1. The heat conductive inner lining layer is used to increase the air tightness and structural strength of the connection with the heat source material, while allowing the heat of the front heat source part 1-1 to be transferred to the aerosol generating part 2 through the heat conductive inner lining layer, thereby forming a certain degree of circumferential heating.

[0080] Preferably, the material of the connecting part 1 - 2 may be thermally conductive, so that the inserted aerosol generating part 2 can be appropriately heated peripherally during use to assist in the formation of internal aerosol.

[0081] The material of the connection part 1-2 may include metal or ceramic heat-conducting materials added inside, and natural or synthetic biomass such as wood retained outside. The increased metal or ceramic heat conductivity can further assist the release and conduction of downstream aerosols. For example, the inner layer of the connection part 1-2 is a metal layer or a ceramic layer, and the outer layer is a wood layer.

[0082] The connecting part 1-2 is preferably a tubular structure.

[0083] The interface between the connecting part 1-2 and the insertion end of the aerosol generating part 2 needs to facilitate the user to insert the aerosol generating part 2, while ensuring the airtightness of the overall structure during the ignition and inhalation process after insertion.

[0084] Figure 5 Three possible implementations are given:

[0085] Mode 1: The downstream section of the connecting part 1-2 is an inner diameter expansion section. The inner diameter expansion section can be formed by setting a circumferential inner concave portion in the connecting part 1-2. The depth and width of the circumferential inner concave portion can be used to control the insertion depth. The inner diameter expansion section can be set in one or more sections, for example, in a multi-layer step shape, to match the aerosol generating part 2 of different diameters.

[0086] Mode 2: The downstream section of the connecting part 1-2 is a section with gradually expanding inner diameter, which allows a certain degree of adjustability of the insertion depth of the aerosol generating part 2. The inner diameter of the section with gradually expanding inner diameter gradually increases from upstream to downstream.

[0087] Mode 3: An internal thread structure is provided on the inner wall of the downstream section of the connecting part 1 - 2 , allowing the aerosol generating part 2 to be rotated and inserted in a tightly fitting manner.

[0088] The combination of the heat source part 1-1, the connection 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, allows the user to adjust the length of the cavity 1-3 after insertion according to needs, bringing different heating effects and sensory experiences. The connection part 1-2 is configured so that the volume of the cavity 1-3 can be adjusted after the aerosol generating part 2 is inserted into 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 heated atomization state.

[0089] In addition, without affecting the suction airflow, the connection part 1-2 can also optimize the inhalable aerosol release characteristics by optimizing the structure of the cavity 1-3 or adding functional materials to help enhance the user's sensory experience during inhalation.

[0090] Preferably, a functional material unit is provided in the cavity 1-3. The functional material unit contains a functional material. The functional material may be a porous adsorbent or a flavor regulator, or an inhalable solvent that assists in the formation of aerosol. The functional material is released during the insertion of the aerosol generating unit 2 and replenishes the aerosol generating unit 2 with an instant atomizer, thereby enriching and improving the inhalation experience.

[0091] The added functional material can be a combination of one or more materials and forms such as particles, high-transmittance membranes, porous media, capsules, etc. Figure 6Three possible implementation methods of adding functional material cavities are given, and the carried components migrate from the functional materials to the aerosol generating part 2 or the air flow along with the hot air flow.

[0092] Figure 6 Middle: Method 1: The functional material part is a porous membrane, and the membrane material can be a functional material for carrying aroma components; Method 2: The functional material part is aroma-carrying particles, and the particles can preferably have a macroporous structure, and the aroma components can be loaded on the surface or inside of the particles; Method 3: The functional material part is a capsule, and the capsule coating can be made of a thermosensitive material, and the aroma components are wrapped inside.

[0093] Preferably, a connector 1-5 can be added in the cavity 1-3 to abut between the heat source part 1-1 and the aerosol generating part 2. The connector 1-5 is preferably a heat-conducting connector, and its material is a heat-conducting material. The heat of the front-stage heat source part 1-1 can be transferred to the surface of the aerosol generating matrix part 2-1 of the aerosol generating part 2 through the heat conduction of the connector 1-5. Figure 7 Two representative designs of the connector 1-5 are given: method 1 - columnar structure; method 2 - "T" structure, where one end of the larger end face of the "T" structure abuts against the heat source part 1-1. This structure can increase the contact area between the connector 1-5 and the heat source part 1-1 and enhance heat extraction.

[0094] Preferably, one end of the larger end face of the "T" structure is a porous end face, which can realize effective transmission of hot air flow. In addition, one or more axial air flow channels can be set in the columnar structure and the "T" structure body to enhance heat extraction.

[0095] Of course, one end of the larger end surface of the "T" structure may also abut against the aerosol generating matrix portion 2-1 to achieve uniform dispersion of heat in the aerosol generating matrix portion 2-1.

[0096] In addition, a connecting member 1-5 with an I-shaped structure may also be provided. The two larger end surfaces of the I-shaped structure abut against the heat source part 1-1 and the aerosol generating part 2 respectively.

[0097] Preferably, the heat source connecting portion 1 includes an extending portion 1-6 connected to the heat source portion 1-1 and extending into the cavity 1-3. Figure 8 As shown, one end of the extension part 1-6 is connected to the heat source part 1-1, and a certain length of the other end is exposed in the cavity 1-3. The extension part 1-6 can have the function of heat conduction, piercing or reinforcement. The extension part 1-6 can be a heat transfer component, a piercing component or a structural reinforcement component, and the specific structure is as follows:

[0098] Preferably, the heat source part 1-1 and the heat transfer component form an integrated structure inside the connecting part 1-2. The heat transfer component is composed of a needle, sheet or rod of metal or other heat conductive material, or a heat pipe with high heat transfer properties. One end of the heat transfer component is connected to the heat source material, and the other end is exposed to a certain length in the cavity 1-3. When the aerosol generating part 2 is inserted into the cavity 1-3, the other end of the heat transfer component, i.e. the exposed end, is inserted into the cavity 1-3, and plays the role of auxiliary or main central heating in the heat generation process of the heat source material, thereby helping the formation and release of aerosol. Fig. 9 .

[0099] Preferably, the heat source portion 1-1 and the piercing component form an integral structure inside the connecting portion 1-2. The piercing component may be needle-shaped, sheet-shaped or rod-shaped. One end of the piercing component is connected to the heat source material, and a certain length of the other end is exposed in the cavity 1-3. When the aerosol generating portion 2 is inserted into the cavity 1-3, the exposed end of the piercing component is inserted into the interior of the aerosol generating portion 2, thereby playing the role of breaking objects that can be crushed or broken. The objects that can be crushed or broken can be capsules containing liquid, solid, or colloidal sustained-release flavor substances or substances that can form aerosols, or releasable substances, which are converted into or enter part or all of the inhalable aerosol when the user inhales the aerosol generating portion 2. See Fig.10 .

[0100] Preferably, the heat source part 1-1 and the structural reinforcement component form an integrated structure inside the connecting part 1-2. The structural reinforcement component can be needle-shaped, sheet-shaped or rod-shaped. One end of the structural reinforcement component is connected to the heat source material, and a certain length of the other end is exposed in the cavity 1-3. When the aerosol generating part is inserted into the cavity 1-3, the exposed end of the structural reinforcement component is inserted into the interior of the aerosol generating part 2, which plays the function of reinforcing the aerosol generating part 2 and the heat source part 1-1. Fig.11 .

[0101] The combination of the heat source part 1-1, the connecting part 1-2 and the aerosol generating part 2 can use a transparent material partially or entirely on the connecting part 1-2 to facilitate the user to clearly design the insertion depth, such as Fig.12 As shown, the connecting portion 1-2 has a perspective window 1-7. The transparent material used for the perspective window 1-7, in addition to having a perspective function, should not release unacceptable toxic or harmful substances that can be inhaled when heated during use.

[0102] Preferably, the heat source part 1-1 and the connecting part 1-2 form a pressable mechanism. Before ignition, the user presses the heat source part 1-1 to the internal ignition position. Fig.13 More preferably, the pressable mechanism contains a crushable or shatterable object, such as a flavoring substance releasing capsule. The user presses the heat source part 1-1 to the internal ignition position before ignition, resulting in the crushable or shatterable object being damaged and the internal slow-release substance being exposed to the airflow channel. Fig.14.

[0103] The heat source part 1-1 and the connecting part 1-3 may form a pressable mechanism in such a way that the downstream end of the connecting part 1-3 has an inner flange, and the heat source part 1-1 is configured to move back and forth in the connecting part 1-3 and move downstream when pressed until it stops against the inner flange.

[0104] Preferably, the aerosol generating section 2 comprises: an aerosol generating substrate section 2-1 located upstream and an inlet suction section 2-2 located downstream.

[0105] The aerosol generating part 2 is a heating consumable, which can be an existing or future electrically heated cigarette or electrically heated aerosol generating product, which contains an aerosol generating matrix such as tobacco and / or an atomizer. As long as it is suitable for being inserted into the heat source connecting part 1, it can be used as a heat-not-burn atomizing product.

[0106] Preferably, the aerosol generating matrix part 2-1 in the aerosol generating part 2 contains bulk heating consumables 1-9, and the inlet suction part 2-2 is a disposable suction nozzle. A heat-resistant flame retardant 1-8 located in the cavity 1-3 is provided in the connecting part 1-2. The disposable suction nozzle is connected to the downstream end of the connecting part 1-2 to form a receiving part for the bulk heating consumables 1-9 between the heat-resistant flame retardant 1-8.

[0107] See Fig.15 The bulk heating consumables 1-9 are added by the user into the cavity 1-3 formed by the heat-resistant flame retardant 1-8 and the disposable suction nozzle 2-2 before use.

[0108] The aerosol generating matrix 2-1 may contain an aerosol generating matrix formed by mixing tobacco and / or non-tobacco plant materials and / or atomizers. The shape of the aerosol generating matrix may be any suitable shape, such as granular, cylindrical, gathered sheets or gathered filaments. If the aerosol generating matrix is ​​granular, a granular blocking member may be provided at the upstream end of the aerosol generating matrix 2-1.

[0109] The inlet suction section 2-2 may include one or more of a hollow section, a cooling section, and a filtering section. A filtering material is arranged in the filtering section to filter the aerosol.

[0110] The heat source connection part 1 of the present application can be used with existing heating consumables or proprietary heating consumables. That is, the aerosol generating part 2 can be an existing commercial electric heating cigarette or similar non-tobacco heating atomization product, or a proprietary heating consumable matching the heat source connection part 1.

[0111] When using commercial electrically heated cigarettes or similar non-tobacco heated atomization products, the insertion diameter of the heat source connection part 1 needs to match the common diameter or circumference of such cigarettes, such as super slim, medium and regular cigarettes.

[0112] Proprietary heating consumables can be disposable atomizing medium consumables containing inhalable atomizers. Atomizing medium can be natural or processed tobacco, plant or chemical synthetic fiber as the atomizing medium matrix of carrier. On the base material, various atomizing media and auxiliary atomizing materials of solid, liquid or colloidal form for atomization can be contained, such as metal parts or particles of auxiliary heat conductivity uniformity. Proprietary heating consumables can be any form of industrial processing and production, such as cylindrical, rectangular, flat column, or irregular solid geometric body, or a combination therebetween, except that the airtight insertion of one end and the heat source connecting part 1 and the mouth suction of the other end are satisfied. The taste or special inhalable substance released by the user when sucking can be contained inside the proprietary heating consumables, such as, the bursting beads that can be crushed by fingers. Various solid, liquid or colloidal atomizing media loaded on the aerosol generating matrix part 2-1 can also be released when exposed to the heated airflow when sucking.

[0113] A method for using the above-mentioned aerosol generating product, the method comprising the following steps:

[0114] like Figure 1 , the initial state is that the heat source connection part 1 and the aerosol generating part 2 are separately arranged;

[0115] Then the aerosol generating part 2 is inserted into the connecting part 1-2 so that the heat source connecting part 1 and the aerosol generating part 2 are connected as a whole. Figure 2 As shown;

[0116] Then, an external fire source is used to ignite the heat source part 1-1, and the heat source part 1-1 burns and releases heat. The user inhales through the downstream end of the aerosol generating part 2, and the outside air enters the heat source part 1-1 and is heated and then flows through the aerosol generating part 2. The aerosol generating part 2 releases aerosol after being heated and is inhaled by the user.
