TECHNICAL FIELD
-
This application relates to the field of electronic atomization technologies, and in particular, to a heating assembly and an aerosol generating apparatus.
BACKGROUND
-
During use of smoking products such as cigarettes or cigars, tobacco is burnt to produce smoke. Attempts have been made to replace these tobacco-burning products by making products that release compounds without burning. An example of the products is a heating and non-burning product that releases a compound by heating rather than burning the tobacco.
-
A low-temperature heating and non-burning aerosol generating apparatus heats an aerosol generating product through a heating assembly. A heating element of the heating assembly is coated with a far-infrared coating and a conductive coating. When energized, the far-infrared coating emits a far-infrared ray to heat the aerosol generating product in the heating element. When the heating assembly is mounted, the heating element is supported and fixed by a mounting base. In the related art, two mounting bases need to be fixed by external components such as vacuum tubes. In this case, mounting is inconvenient, a structure is complex, and costs of the vacuum tubes are high.

DETAILED DESCRIPTION
-
For ease of understanding of this application, this application is described in further detail below with reference to the accompanying drawings and specific implementations. The specific embodiments are merely used to explain this application, but not to limit this application. In addition, it should be further noted that for ease of description, only some structures related to this application rather than all structures are shown in the accompanying drawings.
-
FIG. 1 and FIG. 2 show an aerosol generating apparatus 1000 according to an implementation of this application. The aerosol generating apparatus 1000 includes a heating assembly 100, a cavity 200, a battery cell 300, a circuit 400, and a housing 500. The heating assembly 100, the cavity 200, the battery cell 300, and the circuit 400 are all disposed in the housing 500.
-
The heating assembly 100 is configured to heat an aerosol-forming substrate to generate an inhalable aerosol.
-
In one example, a heater or a heating element in the heating assembly 100 is configured to heat at least a part of an aerosol generating product 101, which is generally referred to as circumferential heating or peripheral heating.
-
In one example, a heater or a heating element in the heating assembly 100 is configured to be inserted into the aerosol generating product 101 for heating, which is generally referred to as central heating or internal heating.
-
In one example, a heating manner of the heating assembly 100 may be resistance heating, infrared heating, electromagnetic induction heating, and the like.
-
The cavity 200 is configured to receive the aerosol-forming substrate.
-
In one example, the aerosol-forming substrate may conveniently be a part of the aerosol generating product 101. The aerosol-forming substrate is a substrate that can release a volatile compound that can form an aerosol. The volatile compound may be released by heating the aerosol-forming substrate. The aerosol-forming substrate may be solid, or liquid, or components including solid and liquid. The aerosol-forming substrate may be carried on a carrier or a support member through absorption, coating, or impregnation, or in another manner.
-
The battery cell 300 supplies power for operating the aerosol generating apparatus 1000. For example, the battery cell 300 may supply power to the heating assembly 100 to implement heating of the aerosol-forming substrate. In addition, the battery cell 300 may supply power for operating other elements provided in the aerosol generating apparatus 1000. The battery cell 300 may be a rechargeable battery or a disposable battery.
-
The circuit 400 may control overall operations on the aerosol generating apparatus 1000. The circuit 400 not only controls operations on the battery cell 300 and the heating assembly 100, but also controls operations on other elements in the aerosol generating apparatus 1000. For example, the circuit 400 obtains a temperature of the heating assembly 100 that is sensed by a temperature sensor, and controls, based on the information, the power supplied by the battery cell 300 to the heating assembly 100.
-
As shown in FIG. 3, FIG. 8, and FIG. 13, the heating assembly 100 includes a heating element 110, a first mounting base 120, a second mounting base 130, and a connecting arm 142 (142' and 142").
-
The heating element 110 is configured to heat the aerosol generating product 101, such as a cigarette, to generate an aerosol. The aerosol generating product is a substrate that can release a volatile compound that can form an aerosol. In the embodiments of this application, as shown in FIG. 10, the aerosol generating product 101 is a cigarette. The heating element 110 is configured to bake the aerosol generating product 101, to form the aerosol for a user to inhale.
-
A suitable aerosol-forming agent is well known in the art, and includes, but is not limited to: polyol such as triethylene glycol, 1,3-butanediol and glycerol; ester of polyhydric alcohol, such as glycerol monoacetate, glycerol diacetate, or glycerol triacetate; and fatty acid esters of monocarboxylic acid, dicarboxylic acid, or polycarboxylic acid, such as dimethyldodecanedioate and dimethyltetradecanedioate. Preferably, the aerosol-forming agent is polyhydric alcohol or a mixture thereof, such as triethylene glycol, or 1,3-butanediol, and most preferably, glycerol.
-
As shown in FIG. 5, an accommodating cavity 1111 is defined in the heating element 110. The accommodating cavity 1111 is configured to accommodate at least a part of the aerosol generating product. The accommodating cavity 1111 forms at least a part of the foregoing cavity 200. In the embodiments of this application, the aerosol generating product is the aerosol generating product 101. During use, the aerosol generating product 101 is placed in the accommodating cavity 1111 on the heating element 110. The heating element 110 receives electrical power from a power supply to generate heat, and transfers the heat to the aerosol generating product 101 in the accommodating cavity 1111, so that at least one component of the aerosol-forming substrate in the aerosol generating product 101 volatilizes to form an aerosol that can be inhaled.
-
Specifically, as shown in FIG. 4, the heating element 110 includes a substrate 111 and an infrared coating 112. The substrate 111 may be made of a high temperature-resistant and transparent material such as quartz glass, ceramics, or mica, or may be made of another material having high infrared ray transmittance such as a high temperature-resistant material whose infrared ray transmittance is greater than 95%, which is not specifically limited herein. The accommodating cavity 1111 is provided on the substrate 111.
-
Because the aerosol generating product in the embodiments of this application is the aerosol generating product 101, and the aerosol generating product 101 is generally in a shape of a cylinder, in the embodiments of this application, as shown in FIG. 4, the accommodating cavity 1111 on the substrate 111 is a cylinder-shaped hole that runs through the substrate 111, so that a shape of the accommodating cavity 1111 is adapted to the aerosol generating product 101, which is convenient for accommodating the aerosol generating product 101. The heating element 110 may be in a shape of a cylinder, or certainly, may be another column shape, such as a polygonal prism. This is not specifically limited herein.
-
The infrared coating 112 is coated on a surface of the substrate 111. The infrared coating 112 may be coated on an outer surface of the substrate 111 or may be coated on an inner surface of the substrate 111. Preferably, the infrared coating 112 is coated on the outer surface of the substrate 111. The infrared coating 112 can generate heat energy when being energized, to heat and bake the aerosol generating product 101 to form an aerosol.
-
In some embodiments, referring to FIG. 17 to FIG. 19, the substrate 111 includes a proximal end and a distal end that are opposite to each other, and a surface extending between the proximal end and the distal end. At least a part of the accommodating cavity 1111 is defined and formed in a hollow part inside the substrate 111. The proximal end of the substrate 111 is provided with a first opening in communication with the hollow part inside the substrate 111, and at least a part of the aerosol generating product 101 is removably received in the substrate 111 through the first opening. When the aerosol generating product 101 is received in the substrate 111, the heating element 110 may perform heating surrounding at least a part of the aerosol generating product 101, which is generally referred to as circumferential heating or peripheral heating. The distal end of the substrate 111 may also have a second opening in communication with the hollow part inside the substrate 111. In another example, the distal end of the substrate 111 may not be provided with the second opening, that is, the distal end of the substrate 111 is closed.
-
A thickness of the substrate 111 ranges from 0.5 mm to 2 mm, or ranges from 0.5 mm to 1.5 mm, or ranges from 0.5 mm to 1 mm.
-
In an example, an inner diameter of the substrate 111 ranges from 6 mm to 15 mm, or ranges from 7 mm to 15 mm, or ranges from 7 mm to 14 mm, or ranges from 7 mm to 12 mm, or ranges from 7 mm to 10 mm. An axial extension length of the substrate 111 ranges from 15 mm to 30 mm, or ranges from 15 mm to 28 mm, or ranges from 15 mm to 25 mm, or ranges from 16 mm to 25 mm, or ranges from 18 mm to 25 mm, or ranges from 18 mm to 24 mm, or ranges from 18 mm to 22 mm. The substrate 111 of the size is suitable for a short and thick aerosol generating product 101.
-
In one example, an inner diameter of the substrate 111 ranges from 5 mm to 5.9 mm, and in a specific example, may be 5.5 mm, 5.4 mm, and the like. An axial extension length of the substrate 111 ranges from 30 mm to 60 mm, ranges from 30 mm to 55 mm, ranges from 30 mm to 50 mm, or ranges from 30 mm to 45 mm, or ranges from 30 mm to 40 mm. The substrate 111 of the size is suitable for an elongated aerosol generating product.
-
The infrared coating 112 receives electric power to generate heat, to further radiate an infrared ray with a specific wavelength, for example, a far-infrared ray of 8 µm to 15 µm. The wavelength of the infrared ray is not limited. The infrared ray may be an infrared ray of 0.75 µm to 1000 µm, and preferably, a far-infrared ray of 1.5 µm to 400 µm. The infrared coating 112 is formed on the surface of the substrate 111.
-
In one example, the infrared coating 112 includes two infrared electrothermal coatings spaced apart in an axial direction, namely, an infrared coating 1121 and an infrared coating 1122 that are shown in the figure. The infrared coating 1121 is closer to a mouthpiece end of the aerosol generating apparatus 1000 than the infrared coating 1122 is. A spacing distance between the infrared coating 1121 and the infrared coating 1122 ranges from 0.2 mm to 1 mm.
-
In one embodiment, the heating element 110 further includes a conductive element, and the conductive element includes a conductive electrode 113a, a conductive electrode 113b, and a conductive electrode 113c that are spaced apart from each other on the substrate 111. Being spaced apart from each other means that there is no direct contact between any two electrodes and a short circuit is formed.
-
The conductive electrode 113a includes a coupling portion 113a1 extending in a circumferential direction of the substrate 111 and a conductive portion 113a2 extending in an axial direction from the coupling portion 113a1 toward the proximal end of the substrate 111. The coupling portion 113a1 is arc-shaped, the coupling portion 113a1 and the infrared coating 1122 are spaced apart, and the coupling portion 113a1 is disposed between the infrared coating 1122 and the distal end of the substrate 111. A wire may be soldered to the coupling portion 113a1, to form an electrical connection with a power supply outside the heating element 110, for example, the battery core 300 or a voltage obtained after the battery core 300 is converted, or may be electrically connected to the power supply by another electrical connecting member. The conductive portion 113a2 is strip-shaped, an axial extension length of the conductive portion 113a2 is greater than an axial extension length of the infrared coating 1122, and an upper end of the conductive portion 113a2 is flush with an upper end of the infrared coating 1122. The conductive portion 113a2 keeps in contact with the infrared coating 1122, to form an electrical connection.
-
The conductive electrode 113b is strip-shaped, and an axial extension length of the conductive electrode 113b is the same as an axial extension length of the infrared coating 1121. The conductive electrode 113b keeps in contact with the infrared coating 1121, to form an electrical connection.
-
A structure of the conductive electrode 113c is similar to that of the conductive electrode 113a. A coupling portion 113c1 of the conductive electrode 113c is disposed between the infrared coating 1122 and a lower end of the substrate 111. A conductive portion 113c2 is strip-shaped, but an axial extension length of the conductive portion 113c2 is greater than a sum of an axial extension length of the infrared coating 1121 and an axial extension length of the infrared coating 1122, and an upper end of the conductive portion 113c2 is flush with an upper end of the infrared coating 1121. The conductive electrode 113c2 keeps in contact with the infrared coating 1121 and the infrared coating 1122, to form an electrical connection.
-
Both an empty electrode 113d and an empty electrode 113e are strip-shaped and are disposed on the infrared coating 1122. An axial extension length of the empty electrode 113d and an axial extension length of the empty electrode 113e are the same as the axial extension length of the infrared coating 1122. Both the empty electrode 113d and the empty electrode 113e are not connected to the battery cell 300 through the wire or the electrode connecting member, and a resistance of the empty electrode is close to zero.
-
The empty electrode 113d is disposed between the conductive electrode 113a and the conductive electrode 113c. The empty electrode 113d separates an infrared electrothermal coating between the conductive electrode 113a and the conductive electrode 113c into three infrared electrothermal sub-coatings (B1, B2, and B3 that are shown in FIG. 19) connected in series between the conductive electrode 113a and the conductive electrode 113c, and the three infrared electrothermal sub-coatings are distributed in the circumferential direction of the substrate 111. Equivalent resistances among the three infrared electrothermal sub-coatings may be the same or different.
-
The empty electrode 113e is disposed between the conductive electrode 113a and the conductive electrode 113c. The empty electrode 113e separates an infrared electrothermal coating between the conductive electrode 113a and the conductive electrode 113c into three infrared electrothermal sub-coatings (B4, B5, and B6 that are shown in FIG. 19) connected in series between the conductive electrode 113a and the conductive electrode 113c, and the three infrared electrothermal sub-coatings are distributed in the circumferential direction of the substrate 111. Equivalent resistances among the three infrared electrothermal sub-coatings may be the same or different.
-
An overall resistance of the infrared coating 1122 may be reduced by disposing the empty electrode 113d and the empty electrode 113e.
-
Similarly, an empty electrode 104h and an empty electrode 104i are also disposed on the infrared coating 1121.
-
Through disposition of conductive elements, the infrared coating 1121 and the infrared coating 1122 may be independently controlled. Specifically, the power supply may be controlled to provide heating power for the infrared coating 1121 and/or the infrared coating 1122. For example, the power supply is first controlled to provide heating power for the infrared coating 1121, to heat an upper half part (a part corresponding to a region of the infrared coating 1121) of the aerosol generating product 101; and then, the power supply is controlled to provide heating power for the infrared coating 1122, to heat a lower half part (a part corresponding to a region of the infrared coating 1122) of the aerosol generating product 101, and vice versa.
-
Alternatively, the power supply is first controlled to provide heating power for the infrared coating 1121, to heat the upper half part of the aerosol generating product 101; and then, the power supply is controlled to simultaneously provide heating power for the infrared coating 1121 and the infrared coating 1122, to heat the entire aerosol generating product 101.
-
Alternatively, the power supply is first controlled to provide heating power for the infrared coating 1122, to heat the lower half part of the aerosol generating product 101; and then, the power supply is controlled to simultaneously provide heating power for the infrared coating 1121 and the infrared coating 1122, to heat the entire aerosol generating product 101.
-
When the infrared coating 1121 is controlled to perform heating, for example, the conductive electrode 113b is electrically connected to a positive pole of the power supply, and the coupling portion 113c1 is electrically connected to a negative pole of the power supply. In this way, a current flows in from the conductive electrode 113b, and flows out from the conductive electrode 113c2 after passing through an infrared electrothermal sub-coating A1, an infrared electrothermal sub-coating A2, and an infrared electrothermal sub-coating A3 in the circumferential direction of the substrate 111. Alternatively, a current flows out from the conductive electrode 113c2 after passing through an infrared electrothermal sub-coating A6, an infrared electrothermal sub-coating A5, and an infrared electrothermal sub-coating A4 in another circumferential direction of the substrate 111.
-
When the infrared coating 1122 is controlled to perform heating, for example, the coupling portion 113a1 is electrically connected to a positive pole of the power supply, and the coupling portion 113c1 is electrically connected to a negative pole of the power supply, a current flows in from the conductive portion 113a2, and flows out from the conductive electrode 113c2 after sequentially passing through an infrared electrothermal sub-coating B1, an infrared electrothermal sub-coating B2, and an infrared electrothermal sub-coating B3 in the circumferential direction of the substrate 111, or after sequentially passing through an infrared electrothermal sub-coating B6, an infrared electrothermal sub-coating B5, and an infrared electrothermal sub-coating B4 in another circumferential direction of the substrate 111. The empty electrode 113d and the empty electrode 113e are not connected to a power supply or a circuit outside the heating element 110, that is, the empty electrode 113d and the empty electrode 113e are suspended, and a current cannot directly flow in from the empty electrode 113d, and then flow out from the conductive portion 113c2 or the conductive portion 113a2. An overall resistance of the infrared coating 1122 may be reduced by disposing the empty electrode 113d and the empty electrode 113e. An empty electrode 113f and an empty electrode 113g are similar to this.

It should be noted that, a heating coating disposed on the substrate 111 is not limited to an infrared electrothermal coating, and may also be another electrothermal coating. That is, after power is supplied, heat is generated, and the heat is transferred to the aerosol-forming substrate through the substrate 111. In this case, the substrate 111 may not need to be transparent to an infrared ray, and only needs to be made of a material with high thermal conductivity.
-
It should be further noted that, in another example, a thermally excited infrared radiation layer (which receives transferred heat and radiates an infrared ray to heat the aerosol-forming substrate) may be used to for implementation, which is also feasible.
