Carbon cup heater and aerosol generating product containing same

Abstract

In the carbon cup heater and the aerosol generating product including the same, the carbon cup heater (1) has a bottom wall and a side wall. A ferromagnetic metal heater (11) is filled between the outer surface and the inner surface of the carbon cup heater (1), and a metal foil (12) is provided on the inner surface of the carbon cup heater (1). This eliminates the need for ignition with fire when used. Furthermore, since a ferromagnetic metal heater is filled between the outer surface and the inner surface of the carbon cup heater (1), the entire carbon cup heater (1) can be easily ignited by using an electromagnetic heating method. Furthermore, the aerosol generating product can be used alone after the carbon cup heater is ignited. Therefore, it is not necessary to consider whether the amount of power of the heating device is sufficient, and there is no restriction from the heating device. Furthermore, the combustion exhaust gas generated when the carbon cup heater is burned is isolated by the metal foil, so it is not inhaled by the human body, and the harmfulness is reduced effectively.

Description

[Technical Field]

[0001] The present invention patent is in the field of aerosol generating products, and specifically relates to carbon cup heaters and aerosol generating products including the same. [Background technology]

[0002] Conventional aerosol-generating products mainly use two methods, electrical heating and carbon heating, to heat the aerosol-generating substrate but not burn it to form inhalable aerosols. This reduces the amount of harmful substances in the aerosol, improving safety and health when inhaling aerosol-generating products. Therefore, non-combustion, heated aerosol-generating products are gaining popularity among consumers.

[0003] However, conventional aerosol generating products generally suffer from problems in terms of convenience during use. Electrically heated aerosol generating products require simultaneous use with a heating device during use, which limits the power consumption of the heating device, resulting in poor usability. Carbon-heated aerosol generating products, on the other hand, do not require an additional heating device during use. However, these products rely on external fire to ignite the carbon heat source, making ignition somewhat difficult. Furthermore, when igniting the carbon heat source, only a portion of the carbon heat source burns, resulting in uneven carbon heating and poor heat conduction. Furthermore, exhaust gases generated by the combustion of the carbon heat source during use are easily inhaled by the user, making the effectiveness of harm reduction unclear.

[0004] In order to solve the above problems, the present invention is proposed. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention provides a carbon cup heater and an aerosol-generating product including the same, in order to improve convenience in the use of the aerosol-generating product. [Means for solving the problem]

[0006] In a first aspect of the present invention, there is provided a carbon cup heater having a bottom wall and a side wall, in which a ferromagnetic metal heater 11 is filled between the outer and inner surfaces of the carbon cup heater 1, and a metal foil 12 is provided on the inner surface of the carbon cup heater 1.

[0007] The carbon cup heater 1 can be ignited by an electromagnetic heating method.

[0008] Preferably, the ferromagnetic metal heater 11 is a ferromagnetic metal particle or a ferromagnetic metal layer.

[0009] Preferably, the metal foil 12 has no holes and covers the entire inner surface of the side wall or the entire inner surface of the bottom wall of the carbon cup heating body 1, or covers the entire inner surface of the side wall and the entire inner surface of the bottom wall of the carbon cup heating body 1, thereby achieving the function of isolating gas.

[0010] In a second aspect, the present invention provides an aerosol-generating product comprising the carbon cup heater described in the first aspect of the present invention, said carbon cup heater 1 being disposed within an aerosol-generating substrate 21 of the aerosol-generating product.

[0011] Preferably, the aerosol-generating substrate 21 further includes a hollow section 22 and / or a temperature-lowering section 23 and / or a filter section 24 downstream of the aerosol-generating substrate 21. That is, the aerosol-generating substrate 21 may include any one, two or three of the hollow section 22, the temperature-lowering section 23 and the filter section 24 downstream of the aerosol-generating substrate 21. Naturally, optimally, these three sections are included in this order.

[0012] Preferably, the hollow section 22 has a At least one There is provided an air supply hole 222. The number of the air supply holes may be one or more.

[0013] Preferably, the carbon cup heater 1 and the aerosol-generating substrate 21 are integrally connected.

[0014] Preferably, the carbon cup heater 1 and the aerosol-generating substrate 21 are separably connected to each other.

[0015] Preferably, the aerosol-generating product further includes a coating layer 3 that coats the carbon cup heater 1. The coating layer 3 contains a thermochromic material. The thermochromic material is a composite material consisting of a color former, a color developer, and a solvent. The color former is selected from, but is not limited to, bromocresol green, fluoran-based compounds, triarylmethane-based compounds, and Schiff base-based compounds. The color developer is selected from, but is not limited to, rare earth ions, phenolic hydroxyl compounds and their derivatives, or carboxyl compounds and their derivatives. The solvent is selected from, but is not limited to, meltable compounds, alcohol-based compounds, higher aliphatic ketone compounds, ester-based compounds, ether-based compounds, amide-based compounds, and carboxylic acid-based compounds. [Effects of the Invention]

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The carbon cup heater of the present invention has a bottom wall and a side wall, and a ferromagnetic metal heater is filled between the outer and inner surfaces of the carbon cup heater. Therefore, when placed in a heating device capable of generating an alternating electromagnetic field, the ferromagnetic metal heater can be heated using electromagnetic heating. The ferromagnetic metal heater easily ignites the entire carbon cup heater from the inside, and the carbon cup heater heats the aerosol-generating substrate to generate aerosol, which is inhaled by the consumer. Furthermore, an aerosol-generating product including the carbon cup heater can be used independently after the carbon cup heater is ignited. The heating device is used only for a short time when the carbon cup heater is ignited, and does not need to be used continuously. Therefore, there is no need to worry about whether the heating device has sufficient power, and there is no restriction on the heating device. Furthermore, ignition by electromagnetic heating can avoid safety concerns associated with ignition by fire.

[0018] 2. In the present invention, a metal foil is provided on the inner surface of the carbon cup heating element to separate the carbon cup heating element from the aerosol-generating substrate. When the carbon cup heating element is burned, the generated combustion exhaust gas is blocked by the metal foil, so the exhaust gas does not enter the aerosol-generating substrate and does not mix with the aerosol generated by heating the aerosol-generating substrate. This prevents the exhaust gas generated when the carbon cup heating element is burned from being inhaled by the human body, thereby effectively reducing harmfulness.

[0019] 3. The carbon cup heater of the present invention is covered with an aerosol-generating substrate. When the entire carbon cup heater is ignited using electromagnetic heating, the heat generated after combustion of the carbon cup heater is uniformly guided to the aerosol-generating substrate through the metal foil inside the carbon cup heater, thereby achieving uniform and rapid heating and improving the user's inhalation experience.

[0020] 4. The carbon cup heater and the aerosol-generating substrate of the aerosol-generating product in the present invention are separably connected, so that it can be applied to conventional aerosol-generating products.

[0021] 5. In the present invention, when the entire inner surface of the bottom wall and the entire inner surface of the side wall of the carbon cup heater are covered with metal foil and the metal foil has no holes, the carbon cup also serves to isolate the aerosol-generating substrate from the air. This allows the aerosol-generating substrate to receive heat and emit aerosol without the passage of outside air. The lack of outside air passage corresponds to the elimination of oxygen, one of the three elements of combustion (combustible material, oxygen, and temperature higher than the ignition point). Therefore, even when heated to very high temperatures (e.g., above 350°C), the aerosol-generating substrate will not burn. This avoids the various harmful aerosol components and burnt odors that accompany combustion, resulting in a more pure aerosol flavor. Furthermore, heating to higher temperatures also increases the amount of aerosol emitted, thereby improving the utilization rate of the aerosol-generating substrate. Furthermore, aroma components that would not normally be released at temperatures above 350°C can be released, resulting in a richer aroma. Furthermore, when a hollow section 22 having an air intake hole 222 is used, the outside air entering through the air intake hole can also have the effect of cooling the aerosol and transporting it downstream, thereby promoting the downstream diffusion of the aerosol inside the aerosol-generating substrate.

DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to better understand the object, structure and function of the present invention, the present invention will be described in more detail below in combination with the drawings.

[0024] In this context, "upstream" to "downstream" are relative terms, and when the aerosol-generating product is heated and inhaled, the direction of aerosol flow within the aerosol-generating product is from "upstream" to "downstream."

[0025] As shown in Figures 1 to 7, The carbon cup heater of the present invention has a bottom wall and a side wall. Ferromagnetic metal particles are filled between the outer and inner surfaces of the carbon cup heater. A heat-permeable, non-air-permeable metal foil 12 is provided on the inner surface of the carbon cup heater.

[0026] The metal foil 12 has no holes and covers the entire inner surface of the side wall and the entire inner surface of the bottom wall of the carbon cup heater 1, thereby isolating the gas.

[0027] In the aerosol-generating product including the carbon cup heater 1, the carbon cup heater 1 is covered with an aerosol-generating substrate 21 of the aerosol-generating product, and the carbon cup heater 1 is separated from the substrate 21 by a metal foil 12. The aerosol-generating substrate 21 can be atomized to form an aerosol.

[0028] The carbon cup heater 1 is located upstream of the aerosol-generating substrate 21 .

[0029] A hollow section 22, a temperature-reducing section 23, and a filter section 24 are connected in this order downstream of the aerosol-generating substrate 21. The hollow section 22 has a At least one An air supply hole 222 is provided.

[0030] Before using the aerosol-generating product, the carbon cup heater 1 is ignited using a heat-activation device 4. The heat-activation device 4 may be an electromagnetic heating device that uses an electromagnetic heating method to heat ferromagnetic metal particles inside the carbon cup heater. As a result, after the entire carbon cup heater 1 is ignited and combustion can be automatically maintained, there is no need to continue using the heater, and the aerosol-generating product can be used alone. Therefore, there is no need to consider whether the heater has sufficient power, and there are no limitations to the heater. Furthermore, because no fire is required, the carbon cup heater 1 can be ignited easily.

[0031] The aerosol-generating substrate 21 can be continuously heated by the heat generated when the carbon cup heater 1 is burned, and the aerosol-generating substrate 21 receives the heat and emits an aerosol. In addition, the exhaust gas generated when the carbon cup heater 1 is burned is discharged from the carbon cup heater 1. 1 Since the metal foil 12 between the aerosol-generating substrate 21 and the aerosol is isolated, the aerosol is not inhaled by the user, reducing the harm to the human body.

[0032] The carbon cup heater 1 and the aerosol-generating substrate 21 are integrally connected, or alternatively, the carbon cup heater 1 and the aerosol-generating substrate 21 are separably connected to each other.

[0033] The aerosol-generating product further includes a coating layer 3 that coats the carbon cup heater 1. The coating layer 3 contains a thermochromic material. The thermochromic material is a composite material consisting of a color former, a color developer, and a solvent. The color former is bromocresol green. and The developer is a rare earth ion and The solvent is a fusible compound isThe thermochromic material exhibits a thermochromic effect in the vicinity of the carbon cup heater 1. The thermochromic material of the coating layer 3 shows different colors in response to changes in temperature, thereby conveying rough temperature information to the user.

[0034] The carbon cup heater 1 and the aerosol-generating substrate 21 are separably connected to each other so that conventional aerosol-generating products can be used interchangeably.

[0035] As can be understood, the present invention has been described with reference to several embodiments. However, as is well known to those skilled in the art, various modifications or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the teachings of the present invention, these features and embodiments may be modified to adapt to particular situations and materials without departing from the spirit and scope of the present invention.
