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, whether it is an external heating method or an internal heating method, heat conduction requires waiting time, but the puffing action will take away the hot air in the aerosol generating product, resulting in insufficient heat in the aerosol generating product after each puff. It takes a long enough time for the aerosol generating product to rise to a temperature suitable for puffing. If the waiting time is not enough, the temperature and concentration of the aerosol inhaled into the user's mouth are low, affecting the taste. Utility Model Content

In some alternative embodiments, the susceptor is on one or either side of the material.

[0087] A consumable is an article comprising or consisting of an aerosol generating material, some or all of which is intended to be consumed by a user during use. A consumable may include one or more other components, such as an aerosol generating material storage area, an aerosol generating material delivery component, an aerosol generating area, a housing, a wrapper, a mouthpiece, a filter and / or an aerosol modifier. 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] See also Figure 1-Figure 15This embodiment provides an aerosol-generating product, including an aerosol-generating section and a packaging material 130. The aerosol-generating section includes an aerosol-forming substrate 110 and a heating element 120. The packaging material 130 covers the aerosol-forming substrate 110 and the heating element 120. The aerosol-forming substrate 110 forms an aerosol under heating conditions; the heating element 120 includes a circumferentially surrounding first portion 121 and a second portion 122 disposed in the first portion 121; the first portion 121 and the second portion 122 are connected to each other along the circumferential direction.

[0096] At least the second part 122 of the heating element 120 includes an electromagnetic induction material. When the aerosol supply device 20 heats the aerosol generating product 10 by electromagnetic heating, the heating element 120 can generate heat under the action of the electromagnetic field. The heating element 120 can be arranged upstream of the aerosol forming substrate 110, downstream of the aerosol forming substrate 110, or at the aerosol forming substrate 110. According to the flow direction of the airflow during suction, the side where the airflow flows out is the downstream of the aerosol forming substrate 110, and the side where the airflow flows in is the upstream of the aerosol forming substrate 110. When the heating element 120 is located upstream of the aerosol forming substrate 110, the heating element 120 can preheat the air that is about to enter the aerosol forming substrate 110. When the heating element 120 is arranged at the aerosol forming substrate 110, the heating element 120 can heat the aerosol forming substrate 110 and the air entering the aerosol forming substrate 110. When the heating element 120 is located downstream of the aerosol-forming substrate 110, the heating element 120 can heat the aerosol of the mixed air flowing out of the aerosol-forming substrate 110. It can be seen that, by providing the heating element 120, the temperature of the air flowing through the sol generation section can be increased in this embodiment, thereby improving the inhalation taste.

[0097] The material of the first part 121 can be the same as or different from the material of the second part 122. When the first part 121 and the second part 122 are made of different materials, the first part 121 and the second part 122 are fixed by bonding or electrostatic adhesion.

[0098] Optionally, the second portion 122 of the heating element 120 includes an electromagnetic induction material, and a concave-convex surface is formed on the surface of the second portion 122, so that the surface area of ​​the second portion 122 is increased, the resistance is increased, and the heating efficiency of the second portion 122 is improved. In some examples, the first portion 121 of the heating element 120 does not include an electromagnetic induction material, and the second portion 122 includes an electromagnetic induction material and forms a concave-convex surface. In some examples, the first portion 121 and the second portion 122 of the heating element 120 both include an electromagnetic induction material, and a concave-convex surface is formed on the surface of the second portion 122. In some examples, the first portion 121 and the second portion 122 of the heating element 120 both include an electromagnetic induction material, and a concave-convex surface is formed on the surface of the first portion 121 and the second portion 122, but the density of the pattern formed by the concave-convex surface on the second portion 122 is greater than the density of the pattern formed by the concave-convex surface on the first portion 121.

[0099] Figure 12-Figure 15 The surface structure of the heating element 120 after unfolding is shown, wherein the surface of the second part 122 is a concave-convex surface, and the surface of the first part 121 is a smooth surface. The concave-convex structure on the surface of the second part 122 can be grooves, dots, pits, etched grooves, or metal printed embossing, and these concave-convex structures form patterns such as mazes, dot matrixes, checkerboards, honeycombs, etc.

[0114] This embodiment also provides an aerosol supply system, which includes an aerosol supply device 20 and the above-mentioned aerosol generating product 10. The aerosol supply device 20 includes a housing 201 and a heating module and an energy supply module disposed in the housing 201. The housing 201 is provided with a receiving cavity. The heating module includes a coil 205 and a heating element. The heating element is disposed in the receiving cavity and forms a heating cavity 204. The heating element is made of electromagnetic material. The coil 205 is disposed around the heating cavity 204. The energy supply module includes a battery assembly 202 and a controller 203.

When the coil 205 is energized, an electromagnetic field is generated, the heating element is heated, and the heat is conducted from the outside to the inside of the aerosol generating product 10. At the same time, the heating element 120 of the aerosol generating section is heated under the electromagnetic action, and the air and the aerosol forming matrix 110 in the aerosol generating product 10 are heated. The inside and outside of the aerosol generating product 10 are heated at the same time, which is beneficial to reduce the temperature difference between the various regions of the aerosol generating product 10 and improve the smoking taste.

[0116] See also Fig.17 In the case where the aerosol-forming substrate 110 is provided with a heating element 120, since the heating element 120 can generate heat in an electromagnetic field, thereby heating the aerosol-forming substrate 110, the heating element on the aerosol supply device 20 can be eliminated. In this case, the receiving cavity of the housing 201 constitutes a heating cavity 204 for receiving the aerosol-generating product 10.
