Description

Technical Field

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

[0002] The aerosol supply system includes an aerosol supply device and an aerosol generating product (such as a tobacco product). The aerosol generating product is inserted into the heating chamber of the aerosol supply device, and the aerosol generating product is heated by the aerosol supply device to obtain an aerosol. This heat-not-burn technology allows the aerosol generating product to release active ingredients in the carbonization stage before combustion, thereby minimizing the generation of tar and harmful substances.

[0003] The heating methods of aerosol supply devices are divided into external heating and internal heating. The internal heating method generally involves inserting a needle-type or sheet-type heating element into the matrix segment of the aerosol generating product to diffuse heat from the center of the aerosol generating product to the outside. The external heating method generally involves using a cylindrical heating element to surround the matrix segment of the aerosol generating product to diffuse heat from the outside of the aerosol generating product to the inside.

[0004] However, regardless of whether it is an external heating method or an internal heating method, heat will be dissipated in the diffusion process, causing the temperature of the substrate far away from the heating element to rise slowly, resulting in large temperature differences in the substrate at various locations within the aerosol-generating product. As a result, the temperature of the aerosol inhaled into the user's mouth also varies greatly, resulting in a poor taste during inhalation and reduced user experience. Utility Model Content

The present disclosure provides an aerosol generating product and an aerosol supply system to at least solve the technical problem in the prior art that the temperature of each region of the aerosol generating product is inconsistent when it is heated, resulting in poor puffing taste.

A consumable may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol generating material to generate an aerosol. The heater may, for example, include a combustible material, a material that can be heated by electrical conduction, or a susceptor.

[0077] A susceptor is a material that can be heated by being penetrated with a varying magnetic field (e.g., an alternating magnetic field). The susceptor can be a conductive material such that its penetration by the varying magnetic field results in inductive heating of the heated material. The heated material can be a magnetic material such that its penetration by the varying magnetic field results in hysteresis heating of the heated material. The susceptor can be both conductive and magnetic such that the susceptor can be heated by both heating mechanisms. In this article, a device configured to generate a varying magnetic field is referred to as a magnetic field generator.

[0078] Aerosol modifiers are substances typically located downstream of an aerosol generation region that are configured to modify the generated aerosol, for example by changing the taste, flavor, acidity, or another characteristic of the aerosol. The aerosol modifier may be disposed in an aerosol modifier release component that is operable to selectively release the aerosol modifier. For example, the aerosol modifier may be an additive or an adsorbent. For example, the aerosol modifier may include one or more of a flavoring, a coloring agent, water, and a carbon adsorbent. For example, the aerosol modifier may be a solid, a liquid, or a gel. The aerosol modifier may be in powder, string, or particle form. The aerosol modifier may be free of filter material.

[0079] An aerosol generator is a device configured to cause an aerosol to be generated from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol generating material to thermal energy so as to release one or more volatiles from the aerosol generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol generating material without heating. For example, the aerosol generator can be configured to subject the aerosol generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0080] The present disclosure relates to an aerosol supply system (which may also be referred to as a vapor supply system), such as a sprayer or an electronic cigarette. In the following description, the term "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term can be used interchangeably with aerosol supply system / device and electronic aerosol supply system / device. In addition, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation", "aerosolization" and "aerosolization" are often used interchangeably.

[0081] Aerosol supply systems (electronic cigarettes) typically (although not always) include modular components, which include a reusable device part and a replaceable (disposable / consumable) cartridge part. Typically, the replaceable cartridge part will include an aerosol generating material and a vaporizer (which can be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power source) and a control circuit. It will be understood that these different parts may include additional elements depending on the function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operating status features, and the replaceable cartridge device part includes a temperature sensor for helping to control the temperature in some cases. The cartridge is electrically and mechanically connected to the control unit for use, for example, using a thread, a bayonet, or a magnetic connection with appropriately arranged electrical contacts. When the aerosol generating material in the cartridge is exhausted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part and the replacement cartridge is attached to its appropriate position. Systems and devices conforming to this type of two-piece modular configuration may generally be referred to as two-piece systems / devices.

[0082] Electronic cigarettes typically have a generally elongated shape. To provide a specific example, some embodiments of the present disclosure will be considered to include such a generally elongated two-piece system using a disposable cartridge. However, it will be understood that the basic principles described herein may be equally applicable to different configurations, such as a one-piece system or a modular system including more than two components, a refillable device and single-use disposables, and other overall shapes, such as high-performance devices based on so-called box-shaped models that typically have a box shape. More generally, it will be understood that certain embodiments of the present disclosure are based on an aerosol supply system that is operationally configured to provide functionality according to the principles described herein, and that the structural aspects of the system configured to provide functionality according to certain embodiments of the present disclosure are not primarily important.

[0083] As described in the background technology, existing aerosol generating products have a technical problem of large temperature differences in the matrix section during the heating process, resulting in poor smoking taste. To this end, the present disclosure provides an aerosol generating product and an aerosol supply system. By improving the design of the matrix section of the aerosol generating product, the temperature distribution of each area of ​​the aerosol generating product is uniform under the same heating technology, thereby improving the smoking taste.

[0084] The structures of the aerosol generating product and the aerosol supply system of the present invention will be described in detail below by way of specific embodiments.

[0085] like Figure 1 As shown, the aerosol generating product 10 has a matrix segment 101, which includes a packaging material 102 and an aerosol-forming matrix 103 and at least one infrared radiation element 104 arranged in the packaging material 102. The aerosol-forming matrix 103 can form an aerosol under heating conditions; the infrared radiation element 104 is arranged in the aerosol-forming matrix 103, generates infrared rays by receiving heat and heats the aerosol-forming matrix 103 at least in a radiation manner.

[0086] The shape of the infrared radiation element 104 may be cylindrical, sheet-like, strip-like, lumpy or granular. The distribution of the plurality of infrared radiation elements 104 in the aerosol-forming substrate 103 may be: distributed at intervals along the length direction of the aerosol-forming substrate 103; distributed at intervals along a direction perpendicular to the length direction of the aerosol-forming substrate 103; or distributed at intervals along the length direction of the aerosol-forming substrate 103 and distributed at intervals along a direction perpendicular to the length direction of the aerosol-forming substrate 103. The spacing distances of the plurality of infrared radiation elements 104 may be the same or different.

[0087] In a possible implementation, the infrared radiation element 104 is made of infrared radiation material, and the material is selected from at least one of graphene, metal foil with ceramic coating, quartz and crystal material. It can be a single infrared radiation material or a composite of multiple infrared radiation materials. The heat capacity of the infrared radiation element 104 is less than 7000W / m*k, the emissivity is less than 1.0, and the wall thickness is less than 0.5mm. Among them, all infrared radiation-related oxides, carbides or carbon materials such as graphene and quartz account for no more than 5% of the aerosol-forming matrix 103, ensuring that the aerosol-forming matrix 103 produces a normal amount of aerosol when heated, and there is no need to increase the length and radial size of the aerosol-generating product 10 for the addition of the infrared radiation element 104.

[0088] Figure 2-Figure 7 A possible distribution of infrared radiation elements 104 in the aerosol-forming substrate 103 is shown.

[0089] See also Figure 2 , the infrared radiation element 104 is constructed into a cylindrical shape similar to the external packaging material 102, and is embedded in the aerosol-forming matrix 103. The length direction of the cylindrical infrared radiation element 104 is consistent with the length direction of the aerosol-generating product 10, and the aerosol-forming matrix 103 is distributed in the space surrounded by the infrared radiation element 104 and between the outer surface of the infrared radiation element 104 and the inner surface of the packaging material 102. The number of cylindrical infrared radiation elements 104 can be one or more. When the number of infrared radiation elements 104 is multiple, the multiple infrared radiation elements 104 can be arranged around the inner wall of the packaging material 102, or can be arranged in an inner and outer nested manner. When the aerosol-generating product 10 is heated, the cylindrical infrared radiation element 104 can radiate heat evenly to the surroundings, reducing the temperature difference of the aerosol-forming matrix 103 in the radial direction.

[0090] The material of the infrared radiation element 104 is preferably graphene, metal foil with ceramic coating, quartz or crystal material. The heat capacity of the infrared radiation element 104 may be 7000 W / m*k or less, preferably less than 6000 W / m*k or less, more preferably 5000 W / m*k or less, more preferably 4000 W / m*k or less, more preferably 3000 W / m*k or less, more preferably 2000 W / m*k or less, more preferably 1000 W / m*k or less, more preferably 500 W / m*k or less, more preferably 300 W / m*k or less, more preferably 200 W / m*k or less. The emissivity of the infrared radiation element 104 may be 1.0 or less, preferably 0.9 or less, more preferably 0.8 or less. The wall thickness of the infrared radiation element 104 may be 0.5 mm or less, preferably 0.2 mm or less, more preferably 0.1 mm or less, more preferably 0.08 mm or less, more preferably 0.06 mm or less, more preferably 0.04 mm or less, more preferably 0.02 mm or less.

[0091] See also Figure 3 , a plurality of infrared radiation elements 104 are spaced apart along the length direction of the aerosol generating article 10, and these infrared radiation elements 104 are configured to be in the shape of a sheet, such as a circle or an ellipse, with an outer contour similar to the cross section of the aerosol generating article 10. When the aerosol generating article 10 is heated, the infrared radiation elements 104 can radiate heat evenly to the surroundings, thereby reducing the temperature difference of the aerosol-forming substrate 103 in the length direction.

[0100] The material of the infrared radiation element 104 is preferably graphene, metal foil with ceramic coating, quartz or crystal material.

[0101] In this embodiment, an infrared radiation element 104 is arranged in the aerosol-forming matrix 103. During the heating process of the aerosol-generating product 10, the infrared radiation element 104 absorbs the heat emitted by the external heat source and radiates the heat to the surroundings, so that the aerosol-forming matrix 103 far away from the external heat source is heated, thereby achieving the effect of making the temperature of the aerosol-forming matrix 103 close to the external heat source and the temperature of the aerosol-forming matrix 103 far away from the external heat source tend to be consistent, thereby improving the mouthfeel during smoking.

[0102] In another possible implementation, the infrared radiation element 104 includes a substrate 105 and an infrared radiation layer 106 formed on at least part of the surface of the substrate 105. The infrared radiation element 104 of this embodiment is a composite of two materials with different functions. The internal substrate 105 is made of electromagnetic induction material and can generate heat in an electromagnetic field. The external infrared radiation layer 106 is made of infrared radiation material and can transfer heat by radiation to diffuse the heat evenly. Among them, the maximum operating temperature of the substrate 105 does not exceed 500°C. The heat capacity of the infrared radiation layer 106 is less than 7000W / m*, the emissivity is less than 1.0, and the wall thickness is less than 0.5mm. The material of the substrate 105 includes iron, cobalt, nickel, gadolinium, erbium or their alloys, and the infrared radiation layer 106 includes graphene or ceramic coating. Among them, the proportion of all infrared radiation elements 104 in the aerosol forming matrix 103 does not exceed 5%, which does not affect the aerosol forming matrix 103 to generate a normal amount of aerosol when heated.

[0103] In one possible implementation, the surface of the substrate is a rough surface. Specifically, the surface of the substrate can be roughened by a laser texturing method or a chemical etching process. Roughening the surface of the substrate is conducive to the infrared radiation coating being firmly attached to the surface of the substrate. After the surface of the substrate is roughened, the resistance of the substrate will increase due to the skin effect, thereby improving the heating efficiency. Compared with a substrate with a smooth surface, the current of a substrate with a rough surface is smaller than that of a substrate with a smooth surface when the two reach the same heating temperature, thereby reducing energy consumption.

[0104] Figure 8 and Fig. 9 A schematic diagram of the structure of an aerosol generating article 10 is shown. Figure 8 and Fig. 9 The aerosol-forming substrate 103 is provided with one or more infrared radiation elements 104, each infrared radiation element 104 includes a substrate 105 and an infrared radiation layer 106 provided on the surface of the substrate 105. The shape of the infrared radiation element 104 can be as follows: Figure 2-Figure 7The infrared radiation layer 106 may be an infrared radiation coating coated on the surface of the substrate 105. The substrate 105 may be made of iron, cobalt, nickel, gadolinium, erbium or alloys thereof which can be used as a magnetic field receptor, and its Curie temperature does not exceed 500°C. The infrared radiation layer 106 is preferably a graphene or ceramic coating. The heat capacity of the infrared radiation layer 106 may be 7000W / m*k or less, preferably 6000W / m*k or less, more preferably 5000W / m*k or less, more preferably 4000W / m*k or less, more preferably 3000W / m*k or less, more preferably 2000W / m*k or less, more preferably 1000W / m*k or less, more preferably 500W / m*k or less, more preferably 300W / m*k or less, more preferably 200W / m*k or less. The emissivity of the infrared radiation layer 106 may be 1.0 or less, preferably 0.9 or less, more preferably 0.8 or less. The wall thickness of the infrared radiation layer 106 may be 0.5 mm or less, preferably 0.2 mm or less, more preferably 0.1 mm or less, more preferably 0.08 mm or less, more preferably 0.06 mm or less, more preferably 0.04 mm or less, more preferably 0.02 mm or less.

[0105] When the aerosol-generating product 10 is heated, the infrared radiation layer 106 absorbs the heat emitted by the external heat source and radiates the heat to the surrounding aerosol-forming substrate 103. Therefore, the aerosol-forming substrate 103 far away from the external heat source will be heated by the infrared radiation layer 106, and its temperature will be as close as possible to the temperature of the aerosol-forming substrate 103 close to the external heat source. The aerosol-generating product 10 can be heated by resistance heating or electromagnetic heating. When the aerosol-generating product 10 is heated by electromagnetic heating, the substrate 105 is heated in the magnetic field environment, and the heat from the substrate 105 will be conducted to the infrared radiation layer 106, and then conducted or radiated from the infrared radiation layer 106 to the aerosol-forming substrate 103, so that each area of ​​the aerosol-forming substrate 103 is evenly heated, and the heating rate of the aerosol-forming substrate 103 is further increased.

[0106] See also Figure 10-12 This embodiment also provides an aerosol supply system, including the above-mentioned aerosol generating product 10 and an aerosol supply device 20 for receiving the aerosol generating product 10.

The heating element 204 generates heat by resistance heating or electromagnetic heating.

The heating element 204 generates heat by resistance. The shape of the heating element 204 can be, for example, needle-shaped or sheet-shaped. When the aerosol generating article 10 is received in the receiving cavity 202, the heating element 204 enters the matrix section 101 of the aerosol generating article 10.

[0108] In another possible implementation, Fig.12 As shown, the heating module includes a shell 201, a heating element 204 and an inductor 205, the shell 201 has a heating cavity, the heating element 204 and the inductor 205 are arranged in the heating cavity, the heating element 204 constructs a receiving cavity 202, the inductor 205 is located between the outer wall of the heating element 204 and the inner wall of the shell 201 and is electrically connected to the battery module 203. The heating element 204 is made of electromagnetic induction material. Preferably, the inductor 205 is configured as a coil arranged around the extractor. The shape of the heating element 204 can be, for example, cylindrical. When the aerosol generating product 10 is received in the receiving cavity 202, the inductor 205 is energized to generate an electromagnetic field, and the heating element 204 generates heat to heat the aerosol generating product 10 to generate an aerosol.

[0109] Since the infrared radiation element 104 is provided in the aerosol-forming matrix 103 of the aerosol-generating product 10, the infrared radiation element 104 is heated to generate infrared rays on the basis of the heating element heating the aerosol-generating product 10, and then the heat is diffused in a radiation manner, which can reduce the temperature difference between the various regions of the aerosol-forming matrix 103, so that the matrix section 101 of the aerosol-generating product 10 is heated evenly, thereby improving the taste of the user when smoking. At the same time, since the infrared radiation element 104 improves the heat utilization efficiency, the heating temperature and time requirements for the heating element 204 are reduced, and the power consumption of the battery module 203 can be saved.
