FIELD
[0001] The present invention relates to the technical field of aerosol generation products,
and more specifically, to a carbon cup heating element and an aerosol generation product
containing same.
BACKGROUND
[0002] Existing aerosol generation products form an aerosol that can be inhaled by users
by heating an aerosol-generating matrix without burning it mainly by means of electric-heating
and carbon-heating, so that the content of harmful substances in the aerosol can be
reduced, thereby improving the safety and health of smoking of aerosol generation
products. Therefore, heat-not-burn aerosol generation products are popular among consumers.
[0003] However, existing aerosol generation products generally have issues with user convenience.
The electric-heating aerosol generation product needs to be used together with a heating
device during use, and it is limited by the power consumption of the heating device,
making it less convenient to use. The carbon-heating aerosol generation products do
not require the additional heating device during use. However, during the heating
process of this type of product, open flames are utilized to ignite a carbon heat
source from the outside, and the ignition is difficult. In addition, when the carbon
heat source is ignited, the carbon heat source can only burn locally, resulting in
non-uniform carbon heating and poor heat conduction capability, and there is also
a problem that when using the aerosol generation product, the waste gas produced by
the combustion of the carbon heat source can easily be inhaled by the user, resulting
in an unclear harm reduction effect.
[0004] In order to solve the above problems, the present invention is proposed.
SUMMARY
[0005] The present invention provides a carbon cup heating element and an aerosol generation
product including the carbon cup heating element, so as to improve the convenience
of using the aerosol generation product.
[0006] The first aspect of the present invention provides a carbon cup heating element,
which includes a bottom wall and a side wall, a ferromagnetic metal heater 11 is filled
between an outer surface and an inner surface of the carbon cup heating element 1,
and a metal foil 12 is arranged on the inner surface of the carbon cup heating element
1.
[0007] The carbon cup heating element 1 can be ignited by electromagnetic heating.
[0008] Preferably, the ferromagnetic metal heater 11 includes ferromagnetic metal particles
or a ferromagnetic metal layer.
[0009] Preferably, the metal foil 12 has no holes and covers the inner surface of the entire
side wall or the inner surface of the entire bottom wall of the carbon cup heating
element 1, or covers the inner surface of the entire side wall and the inner surface
of the entire bottom wall of the carbon cup heating element 1, playing a role in isolating
gas.
[0010] The second aspect of the present invention provides an aerosol generation product
including the carbon cup heating element of the first aspect of the present invention,
the carbon cup heating element 1 is sleeved on an aerosol-generating matrix 21 of
the aerosol generation product.
[0011] Preferably, the downstream of the aerosol-generating matrix 21 further includes a
hollow section 22 and/or a cooling section 23 and/or a filter section 24. That is,
the downstream of the aerosol-generating matrix 21 may include any one, two, or all
three of the following: the hollow section 22, the cooling section 23, and the filter
section 24, and, of course, the most preferred configuration is to have all three
sections in sequence.
[0012] Preferably, the hollow section 22 provides air inlet 222 that is in communication
with the outside environment; the air inlets 222 can be one or multiple.
[0013] Preferably, the carbon cup heating element 1 and the aerosol-generating matrix 21
are integrally connected.
[0014] Preferably, the carbon cup heating element 1 and the aerosol-generating matrix 21
are detachably connected to each other.
[0015] Preferably, the aerosol generation product further includes a wrapping layer 3 wrapping
the carbon cup heating element 1, which has a thermochromic material, the thermochromic
material is a composite material composed of a chromophoric agent, a color-developing
agent, and a solven; the chromophoric agent is selected from but not limited to bromocresol
green, fluorine compounds, triarylmethane compounds or schiff base compounds; the
color developing agent is selected from but not limited to rare earth ions, phenolic
hydroxyl groups compounds and their derivatives or carboxyl groups compounds and their
derivatives; the solvent is selected from but not limited to molten compounds, alcohol
compounds, higher aliphatic ketone compounds, ester compounds, ether compounds, amide
compounds or carboxylic acids compounds.
[0016] Compared with the existing technology, the present invention has the following beneficial
effects:
- 1. The carbon cup heating element of the present invention has the bottom wall and
the side wall, and a ferromagnetic metal heater is filled between the outer surface
and the inner surface of the carbon cup heating element. When the carbon cup heating
element is placed in a heating device that can generate alternating electromagnetic
fields, the ferromagnetic metal heater is heated by means of electromagnetic heating,
the ferromagnetic metal heater easily ignites the whole carbon cup heating element
from the inside, and the carbon cup heating element heats the aerosol-generating matrix
to produce the aerosol for consumers to inhale. The aerosol generation product including
the carbon cup heating element can be used alone after the carbon cup heating element
is ignited, and the heating device is only used for a moment to ignite the carbon
cup heating element and does not need to be continuously used. Therefore, there is
no need to consider whether the heating device has sufficient power, and there is
no limitation of the heating device. In addition, the ignition by means of electromagnetic
heating can also avoid safety hazards associated with open flame ignition.
- 2. The inner surface of the carbon cup heating element of the present invention is
provided with a metal foil, which isolates the carbon cup heating element from the
aerosol-generating matrix. When the carbon cup heating element burns, the generated
combustion waste gas is blocked by the metal foil from entering the aerosol-generating
matrix, so that the aerosol generated by heating the aerosol-generating matrix will
not be mixed with the waste gas. As such, the waste gas generated from the burning
of the carbon cup heating element will not be inhaled into the human body, thus achieving
a good harm reduction effect.
- 3. The carbon cup heating element of the present invention is sleeved on the aerosol-generating
matrix, so that when the entire carbon cup heating element is ignited by means of
electromagnetic heating, the heat generated by the combustion of the carbon cup heating
element can be evenly guided to the aerosol-generating matrix through the metal foil
inside the carbon cup heating element, thereby achieving uniform and quick heating
and providing the user with a good smoking experience.
- 4. The carbon cup heating element of the present invention is detachably connected
to the aerosol-generating matrix of the aerosol generation product, so that it can
be adapted to existing aerosol generation products.
- 5. When the inner surface of entire bottom wall and the inner surface of the entire
side wall of the carbon cup heating element of the present invention are provided
with the metal foil and there is no hole in the metal foil, the carbon cup also plays
a role in isolating the aerosol-generating matrix from the air, so that the aerosol-generating
matrix is heated to release the aerosol in absence of the passage of outside air.
Since there is no passage of outside air, it is equivalent to cancelling the oxygen
of the three elements of combustion (combustible, oxygen, and a temperature higher
than the ignition point), so that the aerosol-generating matrix will not burn even
when heated to a very high temperature (for example, above 350°C). This not only avoids
various harmful aerosol components and burnt smell generated by combustion, but also
makes the released aerosol flavor purer. Furthermore, heating the aerosol-generating
matrix to a higher temperature can increase the released aerosol and improve the utilization
rate of the aerosol-generating matrix, and can release those flavor components with
a release temperature above 350°C that could not be released originally, thereby enriching
the flavor. When the hollow section 22 with the air inlet 222 is used, the outside
air entering from the air inlet can also cool the aerosol and carry it downstream,
thereby promoting the diffusion of the aerosol within the aerosol-generating matrix
in the downstream direction.

DESCRIPTION OF THE EMBODIMENTS
[0019] In order to better understand the purpose, structure and function of the present
invention, the present invention will be described in further detail below in conjunction
with the accompanying drawings.
[0020] In this application, "upstream" to "downstream" are relative terms. When the aerosol
generation product is heated and inhaled, the flowing direction of aerosol in the
aerosol generation product is from "upstream" to "downstream".
[0021] The present invention provides a carbon cup heating element, which includes a bottom
wall and a side wall. Ferromagnetic metal particles are filled between an outer surface
and an inner surface of the carbon cup heating element, and a heat-permeable and air-impermeable
metal foil 12 is arranged on the inner surface of the carbon cup heating element.
[0022] The metal foil 12 has no holes and covers the inner surface of the entire side wall
and the inner surface of the entire bottom wall of the carbon cup heating element
1, playing a role in isolating gas.
[0023] An aerosol generation product including the carbon cup heating element 1 is provided,
the carbon cup heating element 1 is sleeved on the aerosol-generating matrix 21 of
the aerosol generation product, and the carbon cup heating element 1 and the aerosol-generating
matrix 21 are separated by the metal foil 12; the aerosol-generating matrix 21 can
be atomized to form an aerosol.
[0024] The carbon cup heating element 1 is arranged at the upstream of the aerosol-generating
matrix 21.
[0025] A hollow section 22, a cooling section 23 and a filter section 24 are connected sequentially
downstream of the aerosol-generating matrix 21; the hollow section 22 provides air
inlet 222 in communication with the outside.
[0026] Before using the aerosol generation product, the carbon cup heating element 1 is
ignited with a heating start-up device 4. The heating start-up device 4 can be an
electromagnetic heating device which, by means of electromagnetic heating, heats the
ferromagnetic metal particles in the carbon cup heating element, so that the entire
carbon cup heating element 1 is ignited and can self-sustain the combustion. After
that, the aerosol generation product can be used independently without continuing
to use the heating device. Therefore, there is no need to consider whether the power
of the heating device is sufficient, and the carbon cup heating element 1 can be easily
ignited, not limited by the heating device, and not requiring an open flame.
[0027] The heat generated during burning of the carbon cup heating element 1 can continuously
heat the aerosol-generating matrix 21, causing the aerosol-generating matrix 21 to
be heated to release aerosol. The waste gas produced by the burning of the carbon
cup heating element 1 is isolated by the metal foil 12,which is located between the
carbon cup heating element 11 and the aerosol-generating matrix 21, so that the waste
gas will not be inhaled by the user, thereby reducing harm to the human body.
[0028] The carbon cup heating element 1 and the aerosol-generating matrix 21 are integrally
connected, or the carbon cup heating element 1 and the aerosol-generating matrix 21
are detachably connected to each other.
[0029] The aerosol generation product further includes a wrapping layer 3 wrapping the carbon
cup heating element 1. The wrapping layer 3 has a thermochromic material, which is
a composite material composed of a chromophoric agent, a color-developing agent, and
a solvent, the chromophoric agent is selected from bromocresol green, the color-developing
agent is selected from rare earth ions, and the solvent is selected from molten compounds.The
thermochromic material serves as a temperature indicator near the carbon cup heating
element 1,the thermochromic material in the wrapping layer 3 displays different colors
with temperature changes to indicate approximate temperature information to the user.
[0030] When the carbon cup heating element 1 is detachably connected to the aerosol-generating
matrix 21, making it compatible with existing aerosol generation products.
