Background Art

Smoking articles such as cigarettes and cigars burn tobacco to produce smoke during use. Attempts have been made to provide alternatives to these tobacco-burning articles by products that release compounds without burning. Examples of such products are so-called heat-not-burn products, which release compounds by heating tobacco rather than burning it.

The low-temperature heating non-combustion aerosol generating device heats the aerosol generating product through a heating component. The heating element of the heating component is coated with a far-infrared coating and a conductive coating. After being energized, the far-infrared coating emits far-infrared rays to heat the aerosol generating product in the heating element. When the heating component is installed, the heating element is supported and fixed by a mounting seat. In the prior art, two mounting seats need to be fixed by external components such as vacuum tubes, which is inconvenient to install, has a complex structure, and has a high cost for vacuum tubes.

DETAILED DESCRIPTION

In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments are only used to explain the present application, rather than to limit the present application. In addition, it should be noted that, for the sake of ease of description, only partial structures related to the present application are shown in the accompanying drawings, rather than all structures.

1-2 show an aerosol generating device 1000 provided in an embodiment of the present application, including a heating component 100, a chamber 200, a battery cell 300, a circuit 400 and a housing 500. The heating component 100, the chamber 200, the battery cell 300 and the circuit 400 are all disposed in the housing 500.

The heating assembly 100 is used to heat the aerosol-forming substrate to generate an inhalable aerosol.

In one example, the heater or heating element in the heating assembly 100 is configured to heat around at least a portion of the aerosol-generating article 101 , which is commonly referred to as circumferential heating or peripheral heating.

In one example, the heater or heating element in the heating assembly 100 is configured to be inserted into the aerosol-generating article 101 for heating, which is commonly referred to as core heating or internal heating.

In one example, the heating method of the heating component 100 can be resistance heating, infrared heating, electromagnetic induction heating, etc.

The chamber 200 is used to receive the aerosol-forming substrate.

In one example, the aerosol-forming substrate may conveniently be part of the aerosol-generating article 101. An aerosol-forming substrate is a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds can be released by heating the aerosol-forming substrate. The aerosol-forming substrate may be solid or liquid or include solid and liquid components. The aerosol-forming substrate may be adsorbed, coated, impregnated or otherwise loaded onto a carrier or support.

The battery cell 300 provides power for operating the aerosol generating device 1000. For example, the battery cell 300 can provide power to the heating assembly 100 to achieve heating of the aerosol-forming substrate. In addition, the battery cell 300 can provide power required to operate other components provided in the aerosol generating device 1000. The battery cell 300 can be a rechargeable battery or a disposable battery.

The circuit 400 can control the overall operation of the aerosol generating device 1000. The circuit 400 not only controls the operation of the battery cell 300 and the heating assembly 100, but also controls the operation of other components in the aerosol generating device 1000. For example, the circuit 400 obtains the temperature of the heating assembly 100 sensed by the temperature sensor, and controls the power provided by the battery cell 300 to the heating assembly 100 according to the information.

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 ′, 142 ″).

The heating element 110 is used 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 volatile compounds that can form an aerosol. In the embodiment of the present application, as shown in FIG. 10 , the aerosol generating product 101 is a cigarette. 110 is used to bake the aerosol generating product 101 to form aerosol for users to inhale.

Suitable aerosol formers are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butylene glycol and glycerol; esters of polyols such as glycerol mono-, di- or triacetate; and fatty acid esters of mono-, di- or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanoic acid. Preferred aerosol formers are polyhydric alcohols or mixtures thereof such as triethylene glycol, 1,3-butylene glycol and most preferably glycerol.

As shown in FIG5 , a housing cavity 1111 is defined in the heating element 110, and the housing cavity 1111 is used to accommodate at least part of the aerosol generating product, wherein the housing cavity 1111 constitutes at least part of the above-mentioned chamber 200. In the embodiment of the present application, the aerosol generating product is an aerosol generating product 101. When in use, the aerosol generating product 101 is placed in the housing cavity 1111 on the heating element 110, and the heating element 110 receives the electric power of the power source to generate heat, and transfers the heat to the aerosol generating product 101 in the housing cavity 1111, so that at least one component of the aerosol-forming matrix in the aerosol generating product 101 volatilizes to form an aerosol that can be inhaled.

Specifically, as shown in FIG4 , the heating element 110 includes a substrate 111 and an infrared coating 112. The substrate 111 can be made of a high temperature resistant and transparent material such as quartz glass, ceramics or mica, or can be made of other materials with a high infrared transmittance, for example, a high temperature resistant material with an infrared transmittance of more than 95%, which is not specifically limited here. The accommodating cavity 1111 is disposed on the substrate 111.

Since the aerosol generating product in the embodiment of the present application adopts the aerosol generating product 101, and the aerosol generating product 101 is generally cylindrical, therefore, in the embodiment of the present application, as shown in FIG4 , the accommodating cavity 1111 on the substrate 111 is a cylindrical hole penetrating the substrate 111, so that the shape of the accommodating cavity 1111 is adapted to the aerosol generating product 101, so as to facilitate the accommodating of the aerosol generating product 101. The heating element 110 may be cylindrical, of course, or other cylindrical shapes, such as a polygonal column, which is not specifically limited here.

The infrared coating 112 is coated on the surface of the substrate 111. The infrared coating 112 can be coated on the outer surface of the substrate 111 or on the 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 powered on, thereby heating and baking the aerosol generating article 101 to form an aerosol.

In some embodiments, please refer to Figures 17-19, the substrate 111 includes a proximal end and a distal end relative to each other, and a surface extending between the proximal end and the distal end. The hollow portion inside the substrate 111 defines at least a portion of the accommodating cavity 1111. The proximal end of the substrate 111 is provided with a first opening that is connected to the hollow portion inside the substrate 111, and at least a portion of the aerosol generating article 101 is removably received in the substrate 111 through the first opening. When the aerosol generating article 101 is received in the substrate 111, the heating element 110 can heat at least a portion of the aerosol generating article 101, which is generally referred to as circumferential heating or peripheral heating. The distal end of the substrate 111 may also have a first opening that is connected to the substrate 111. The second opening communicates with the inner hollow portion. In other examples, the distal end of the substrate 111 may not be provided with a second opening, that is, the distal end of the substrate 111 is closed.

The thickness of the substrate 111 is between 0.5 mm and 2 mm, or between 0.5 mm and 1.5 mm, or between 0.5 mm and 1 mm.

In one example, the inner diameter of the substrate 111 is between 6 mm and 15 mm, or between 7 mm and 15 mm, or between 7 mm and 14 mm, or between 7 mm and 12 mm, or between 7 mm and 10 mm. The axial extension length of the substrate 111 is between 15 mm and 30 mm, or between 15 mm and 28 mm, or between 15 mm and 25 mm, or between 16 mm and 25 mm, or between 18 mm and 25 mm, or between 18 mm and 24 mm, or between 18 mm and 22 mm. The substrate 111 of this size is suitable for a short and thick aerosol generating article 101.

In one example, the inner diameter of the substrate 111 is between 5 mm and 5.9 mm, and in a specific example, it can be 5.5 mm, 5.4 mm, etc. The axial extension length of the substrate 111 is between 30 mm and 60 mm, or between 30 mm and 55 mm, or between 30 mm and 50 mm, or between 30 mm and 45 mm, or between 30 mm and 40 mm. The substrate 111 of this size is suitable for a slender aerosol generating article.

The infrared coating 112 receives electric power to generate heat, and then radiates infrared rays of a certain wavelength, for example, far infrared rays of 8 μm to 15 μm. The wavelength of the infrared rays is not limited, and can be infrared rays of 0.75 μm to 1000 μm, preferably far infrared rays 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 the axial direction, as shown in the figure as infrared coating 1121 and infrared coating 1122. The infrared coating 1121 is closer to the mouth end of the aerosol generating device 1000 than the infrared coating 1122. The spacing distance between the infrared coating 1121 and the infrared coating 1122 is between 0.2 mm and 1 mm.

In one embodiment, the heating element 110 further includes a conductive element, which includes conductive electrodes 113a, 113b and 113c spaced apart from each other on the substrate 111. Spaced apart from each other means that any two electrodes are not in direct contact to form a short circuit.

The conductive electrode 113a includes a coupling portion 113a1 extending along the circumferential direction of the substrate 111 and a conductive portion 113a2 extending axially from the coupling portion 113a1 toward the proximal end of the substrate 111. The coupling portion 113a1 is in an arc shape, and the coupling portion 113a1 is spaced apart from the infrared coating 1122, and the coupling portion 113a1 is arranged between the infrared coating 1122 and the distal end of the substrate 111; a wire can be welded on the coupling portion 113a1 to form an electrical connection with a power source outside the heating element 110, such as the battery cell 300 or the voltage converted by the battery cell 300, or it can be electrically connected to the power source through other electrical connectors. The conductive portion 113a2 is in a strip shape, and the axial extension length is greater than the axial extension length of the infrared coating 1122, and the upper end of the conductive portion 113a2 is flush with the upper end of the infrared coating 1122; the conductive portion 113a2 maintains contact with the infrared coating 1122 to form an electrical connection.

The conductive electrode 113b is in a strip shape, and its axially extending length is the same as the axially extending length of the infrared coating 1121. The conductive electrode 113b is in contact with the infrared coating 1121 to form a Into electrical connection.

The structure of the conductive electrode 113c is similar to that of the conductive electrode 113a. The coupling portion 113c1 of the conductive electrode 113c is disposed between the infrared coating 1122 and the lower end of the substrate 111, and the conductive portion 113c2 is in a strip shape, but its axially extending length is greater than the sum of the axially extending lengths of the infrared coating 1121 and the infrared coating 1122, and the upper end of the conductive portion 113c2 is flush with the upper end of the infrared coating 1121. The conductive electrode 113c2 is in contact with both the infrared coating 1121 and the infrared coating 1122 to form an electrical connection.

The empty electrode 113d and the empty electrode 113e are both in a strip shape and are disposed on the infrared coating 1122. The axially extending length of the empty electrode 113d and the empty electrode 113e is the same as the axially extending length of the infrared coating 1122. The empty electrode 113d and the empty electrode 113e are not connected to the battery cell 300 through a wire or an electrode connector, and the 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 the infrared electrothermal coating between the conductive electrode 113a and the conductive electrode 113c into three sub-infrared electrothermal coatings (shown as B1, B2, and B3 in FIG. 19 ) connected in series between the conductive electrode 113a and the conductive electrode 113c. The three sub-infrared electrothermal coatings are distributed along the circumferential direction of the substrate 111; the equivalent resistances between the three sub-infrared electrothermal 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 the infrared electrothermal coating between the conductive electrode 113a and the conductive electrode 113c into three sub-infrared electrothermal coatings (shown as B4, B5, and B6 in FIG. 19 ) connected in series between the conductive electrode 113a and the conductive electrode 113c. The three sub-infrared electrothermal coatings are distributed along the circumferential direction of the substrate 111; the equivalent resistances between the three sub-infrared electrothermal coatings may be the same or different.

By providing the empty electrodes 113d and 113e, the overall resistance of the infrared coating 1122 can be reduced.

Similarly, empty electrodes 104h and 104i are also provided on the infrared coating 1121 .

By setting the conductive element, the infrared coating 1121 and the infrared coating 1122 can be controlled independently. Specifically, the power supply can be controlled to provide heating power to the infrared coating 1121 and/or the infrared coating 1122; for example, the power supply is first controlled to provide heating power to the infrared coating 1121 to heat the upper half of the aerosol generating product 101 (the portion corresponding to the infrared coating 1121 area); and then the power supply is controlled to provide heating power to the infrared coating 1122 to heat the lower half of the aerosol generating product 101 (the portion corresponding to the infrared coating 1122 area). The reverse is also possible.

Alternatively, the power supply is first controlled to provide heating power to the infrared coating 1121 to heat the upper half of the aerosol generating product 101 ; and then the power supply is controlled to provide heating power to the infrared coating 1121 and the infrared coating 1122 simultaneously to heat the entire aerosol generating product 101 .

Alternatively, the power supply is first controlled to provide heating power to the infrared coating 1122 to heat the lower half of the aerosol generating product 101; and then the power supply is controlled to provide heating power to the infrared coating 1121 and the infrared coating 1122 at the same time to heat the entire aerosol generating product 101.

When controlling the heating of the infrared coating 1121, for example, the conductive electrode 113b is electrically connected to the positive pole of the power supply, and the coupling part 113c1 is electrically connected to the negative pole of the power supply; in this way, the current flows into the conductive electrode 113b, passes through the sub-infrared electrothermal coatings A1, A2, and A3 along the circumferential direction of the substrate 111, and then flows out from the conductive electrode 113c2; or, passes through the sub-infrared electrothermal coatings A6, A5, and A4 along another circumferential direction of the substrate 111, and then flows out from the conductive electrode 113c2.

When controlling the infrared coating 1122 to heat, for example, the coupling portion 113a1 is electrically connected to the positive electrode of the power source, and the coupling portion 113c1 is electrically connected to the negative electrode of the power source, and the current flows in from the conductive portion 113a2, and passes through the sub-infrared electrothermal coating B1, the sub-infrared electrothermal coating B2, and the sub-infrared electrothermal coating B3 in the circumferential direction of the substrate 111, or passes through the sub-infrared electrothermal coating B6, the sub-infrared electrothermal coating B5, and the sub-infrared electrothermal coating B4 in another circumferential direction of the substrate 111, and then flows out from the conductive electrode 113c2. The empty electrode 113d and the empty electrode 113e are not connected to the power source or circuit outside the heating element 110, that is, the empty electrode 113d and the empty electrode 113e are suspended, and the current cannot flow directly from the empty electrode 113d, and then flow out from the conductive portion 113c2 or the conductive portion 113a2. The existence of the empty electrodes 113d and 113e can reduce the overall resistance of the infrared coating 1122. The empty electrodes 113f and 113g are similar.

It should be noted that the heating coating provided on the substrate 111 is not limited to infrared electric heating coating, but may also be other electric heating coatings, that is, heat is generated after being energized, and the heat is transferred to the aerosol-forming matrix through the substrate 111. In this case, the substrate 111 does not need to be infrared-proof, and only needs to be made of a material with high thermal conductivity.

It should also be noted that in other examples, a thermally excited infrared radiation layer (which receives the transferred heat and radiates infrared rays to heat the aerosol-forming substrate) may be used to achieve this, which is also feasible.

As shown in FIG20 , the first electrode connector 105 includes a strip-shaped body 105a. The body 105a is in contact with the conductive electrode 113b, thereby forming an electrical connection. The body 105a has a pin 105b extending radially outward, and a wire electrically connected to the battery cell 300 can be welded to the pin; in the example in the figure, two pins 105b are arranged at intervals. In a further implementation, a cantilever 105a1 is hollowed out on the strip-shaped body, and the cantilever 105a1 is conducive to maintaining contact with the conductive electrode 113b.
