Fig. 3 to 4 are diagrams showing a first heater according to an embodiment of the present application, and the heater 11 includes:
the substrate 110 may be made of a high temperature resistant transparent material such as quartz glass, ceramic or mica, or may be made of other materials having high infrared transmittance, for example: the high temperature resistant material having an infrared transmittance of 95% or more is not particularly limited herein.
The base 110 has a substantially tubular shape, and preferably has a circular tubular shape. The hollow interior of the substrate 110 defines or forms a chamber that receives an aerosol-forming substrate. The inner diameter of the base 110 is between 7mm and 14mm, or between 7mm and 12mm, or between 7mm and 10mm.
An aerosol-forming substrate is a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds may be released by heating the aerosol-forming substrate. The aerosol-forming substrate may be solid or liquid or comprise solid and liquid components. The aerosol-forming substrate may be adsorbed, coated, impregnated or otherwise loaded onto a carrier or support. The aerosol-forming substrate may conveniently be part of an aerosol-generating article.
The aerosol-forming substrate may comprise nicotine. The aerosol-forming substrate may comprise tobacco, for example may comprise a tobacco-containing material comprising volatile tobacco flavour compounds which are released from the aerosol-forming substrate when heated. The aerosol-forming substrate may comprise at least one aerosol-forming agent, which may be any suitable known compound or mixture of compounds that, in use, facilitates the formation of a dense and stable aerosol and is substantially resistant to thermal degradation at the operating temperature of the aerosol-generating system. Suitable aerosol formers are well known in the art and include, but are not limited to: polyols, such as triethylene glycol, 1, 3-butanediol and glycerol; esters of polyols, such as glycerol mono-, di-or triacetate; and fatty acid esters of mono-, di-or polycarboxylic acids, such as dimethyldodecanedioate and dimethyltetradecanedioate.
An infrared electrothermal coating 111 is formed on the surface of the substrate 110. The infrared electrothermal coating 111 may be formed on the outer surface of the base 110 or may be formed on the inner surface of the base 110. Preferably, the external electrothermal coating 111 is formed on the outer surface of the base 110. The infrared electrothermal coating 111 extends along the axial direction of the substrate 110 by a length of 5 mm-40 mm; or 5mm to 30mm; or 5mm to 20mm; or between 10mm and 20mm.
The infrared electrothermal coating 111 receives electric power to generate heat, and then radiates infrared rays with a certain wavelength, for example: far infrared rays of 8-15 μm. When the wavelength of the infrared light matches the absorption wavelength of the aerosol-forming substrate, the energy of the infrared light is readily absorbed by the aerosol-forming substrate. In this example, the wavelength of the infrared ray is not limited, and may be an infrared ray of 0.75 μm to 1000 μm, preferably a far infrared ray of 1.5 μm to 400 μm.
The infrared electrothermal coating 111 is arranged at the upper end of the substrate 110 with a spacing distance of 0.2 mm-1 mm, which is beneficial to manufacturing production. The infrared electrothermal coating 111 and the lower end of the substrate 110 are also arranged at intervals, the interval distance is 1 mm-4 mm, the arrangement of the conductive electrode is facilitated, and meanwhile, the lower end of the substrate 110 is prevented from being too high in temperature. The upper end of the base 110 is located downstream of the lower end of the base 110 in terms of the flow direction of the aerosol.
The conductive element includes conductive electrodes 112a, 112b, connection electrodes 113a, and 113b disposed on the surface of the substrate 110 at intervals from each other. By spaced apart is meant that no direct contact between any two electrodes forms a short circuit.
The conductive electrode 112a includes a coupling portion 112a1 extending in the circumferential direction of the base 110 and a conductive portion 112a2 extending axially from the coupling portion 112a1 toward the upper end of the base 110. The coupling part 112a1 is arc-shaped, the coupling part 112a1 is arranged at intervals with the infrared electrothermal coating 111, and the coupling part 112a1 is arranged between the infrared electrothermal coating 111 and the lower end of the substrate 110; wires may be soldered to the coupling portion 112a1 to form an electrical connection with a power source external to the heater 11, such as the battery cell 7 or a voltage converted by the battery cell 7, or may be electrically connected with the power source through other electrical connectors. The conductive part 112a2 is in a strip shape, and the axial extension length is longer than that of the infrared electrothermal coating 111; the conductive portion 112a2 is held in contact with the infrared electrothermal coating 111 to form an electrical connection. The conductive electrode 112b has a structure similar to that of the conductive electrode 112a, and the conductive electrode 112b and the conductive electrode 112a are symmetrically arranged on the base 110.
As can be seen in fig. 3, conductive portion 112a2 and conductive portion 112b2 separate infrared electrothermal coating 111 into left and right halves. The connection electrode 113a is disposed in the right half infrared electrothermal coating 111, and the connection electrode 113b is disposed in the left half infrared electrothermal coating 111. The left half infrared electrothermal coating 111 and the right half infrared electrothermal coating 111 are connected in parallel between the conductive portion 112a2 and the conductive portion 112b 2.
The connection electrode 113a has a bar shape and extends axially the same length as the right half of the infrared electrothermal coating 111. The connection electrode 113a divides the right half infrared electrothermal coating 111 into two sub infrared electrothermal coatings (indicated by A1, A2 in fig. 4) connected in series between the conductive portion 112A2 and the conductive portion 112b2, the sub infrared electrothermal coating A1 and the sub infrared electrothermal coating A2 being distributed along the circumferential direction of the base 110; the equivalent resistance of the sub-infrared electrothermal coating A1 and the equivalent resistance of the sub-infrared electrothermal coating A2 can be the same or different. By providing the connection electrode 113a, the overall resistance of the right half infrared electrothermal coating 111 can be reduced. For example, the entire resistance of the right half of the infrared electrothermal coating 111 can be reduced by about 20% by disposing 1 connection electrode 113a between the conductive part 112a2 and the conductive part 112b 2.
It should be noted that, as needed, a plurality of connection electrodes 113a may be provided in the right half infrared electrothermal coating 111 to divide the right half infrared electrothermal coating 111 into a plurality of sub infrared electrothermal coatings connected in series between the conductive portions 112a2 and 112b 2; for example: the 2 connection electrodes 113a are divided into 3 sub-infrared electrothermal coatings connected in series between the conductive part 112a2 and the conductive part 112b2, and the equivalent resistances of the 3 sub-infrared electrothermal coatings may all be the same or all be different, or the equivalent resistances of the 2 sub-infrared electrothermal coatings are the same.
Similarly, the connection electrode 113b is divided into sub-infrared electrothermal coatings as shown in fig. 4 A3 and A4.
After the heater 11 is energized, for example, the coupling portion 112A1 is electrically connected to the positive electrode of the power supply, the coupling portion 112b1 is electrically connected to the negative electrode of the power supply (or vice versa), and the current flows in from the conductive portion 112A2, sequentially passes through the sub-infrared electrothermal coating A1 and the sub-infrared electrothermal coating A2, or sequentially passes through the sub-infrared electrothermal coating A3 and the sub-infrared electrothermal coating A4, and then flows out from the conductive portion 112b 2. The connection electrode 113a and the connection electrode 113b are not connected to a power source or a circuit outside the heater 11, that is, the connection electrode 113a and the connection electrode 113b are suspended, and current cannot directly flow in from the connection electrode 113a and then flow out from the conductive portion 112b2 or the conductive portion 112a2.
The conductive electrode 112a, the conductive electrode 112b, the connection electrode 113a, and the connection electrode 113b preferably employ a continuous conductive coating, and the conductive coating may be a metal coating, and the metal coating may include silver, gold, palladium, platinum, copper, nickel, molybdenum, tungsten, niobium, or a metal alloy material thereof. The widths of the connection electrode 113a and the connection electrode 113b are 0.5mm to 3mm; or 0.5mm to 2.5mm; in a specific example, the thickness may be 1mm or 2mm.
In other examples, the connection electrode 113a and/or the connection electrode 113b may also employ a discontinuous conductive coating, such as the conductive coating having a mesh as shown in fig. 5.
In the process of manufacturing the heater 11, the connection electrode 113a and/or the connection electrode 113b may be disposed between the substrate 110 and the infrared electrothermal coating 111 along a direction perpendicular to the surface of the substrate 110; an infrared electrothermal coating 111 may also be disposed between the substrate 110 and the connection electrode.
In addition, unlike the above examples, in other examples, at least one of the conductive electrode 112a, the conductive electrode 112b, the connection electrode 113a, and the connection electrode 113b may be attached to the infrared electrothermal coating 111. For example: at least one of the conductive electrode 112a, the conductive electrode 112b, the connection electrode 113a and the connection electrode 113b may be coated on an inner wall of a sleeve, and the sleeve is sleeved on the substrate 110, so that at least one of the conductive electrode 112a, the conductive electrode 112b, the connection electrode 113a and the connection electrode 113b is closely attached to the infrared electrothermal coating 111; the arrangement of the conductive electrode 112a, the conductive electrode 112b, the connection electrode 113a, and the connection electrode 113b can be referred to the above examples.
Fig. 6 is a second heater provided in an embodiment of the present application.
Unlike fig. 3 to 4, the conductive electrode 112a and the conductive electrode 112b each have a ring shape and extend in the circumferential direction of the base 110; a plurality of connection electrodes 113a are provided between the conductive electrode 112a and the conductive electrode 112b, and the connection electrodes 113a are also annular; the plurality of connection electrodes 113a divide the infrared electrothermal coating 111 into 4 sub-infrared electrothermal coatings (shown as A1, A2, A3, A4 in the figure) connected in series between the conductive portion 112A2 and the conductive portion 112b 2. The equivalent resistances of the 4 sub-infrared electrothermal coatings are all different. Thus, on one hand, the overall resistance of the infrared electrothermal coating 111 is reduced, and on the other hand, the uniformity of the temperature field of the substrate 110 can be improved.
In this example, the 4 sub-infrared electrothermal coatings are distributed along the axial direction of the base 110, and the length of the connection electrode 113a extending along the circumferential direction of the base 110 is the same as the length of the infrared electrothermal coating 111 extending along the circumferential direction of the base 110.
It should be noted that, in other examples, the connection electrode 113a may have an arc shape.
After the heater 11 is energized, for example, the conductive electrode 112a is electrically connected to the positive electrode of the power supply, the conductive electrode 112b is electrically connected to the negative electrode of the power supply, and the current flows from the conductive electrode 112a, sequentially passes through the sub-infrared electrothermal coating A1, the sub-infrared electrothermal coating A2, the sub-infrared electrothermal coating A3, and the sub-infrared electrothermal coating A4, and then flows out from the conductive electrode 112 b.
Fig. 7 is a third heater provided in an embodiment of the present application.
Unlike fig. 6, the conductive element includes a conductive electrode 112c spaced apart from other conductive electrodes and connection electrodes. The conductive electrode 112a, the conductive electrode 112b and the conductive electrode 112c divide the infrared electrothermal coating 111 into an upper independent heating area and a lower independent heating area; by controlling the two independent heating areas to start heating, the aerosol-forming substrate can be heated in a segmented manner; for example, the heating zone of the upper half is first activated to heat the corresponding upper half of the article; then starting the heating area of the lower half part to heat the corresponding lower half part of the product; or, firstly starting the heating area of the upper half part to heat the corresponding upper half part of the product; the entire heating zone is then activated again to heat the entire article.
The connection electrode 113a is disposed between the conductive electrode 112a and the conductive electrode 112c, and the connection electrode 113a divides the heating area of the upper half into two sub-infrared electrothermal coatings (shown as A1 and A2 in the drawing) connected in series between the conductive electrode 112a and the conductive electrode 112c.
The connection electrode 113b is disposed between the conductive electrode 112c and the conductive electrode 112b, and the connection electrode 113b divides the heating area of the lower half into two sub-infrared electrothermal coatings (shown as A3 and A4 in the drawing) connected in series between the conductive electrode 112c and the conductive electrode 112 b.
When the heating region of the upper half is started, for example, the conductive electrode 112a is electrically connected to the positive electrode of the power supply, the conductive electrode 112c is electrically connected to the negative electrode of the power supply, and current flows from the conductive electrode 112a, sequentially passes through the sub-infrared electrothermal coating A1 and the sub-infrared electrothermal coating A2, and then flows out from the conductive electrode 112c.
When the heating region of the lower half is started, for example, the conductive electrode 112c is electrically connected to the positive electrode of the power supply, the conductive electrode 112b is electrically connected to the negative electrode of the power supply, and current flows from the conductive electrode 112c, sequentially passes through the sub-infrared electrothermal coating A3 and the sub-infrared electrothermal coating A4, and then flows out from the conductive electrode 112 b.
Fig. 8 is a fourth heater provided in an embodiment of the present application.
Unlike fig. 3 to 4, the conductive electrode 112a and the conductive electrode 112b each extend spirally in the axial direction of the base 110; 1 connecting electrode 113a is arranged between the conductive electrode 112a and the conductive electrode 112b, the connecting electrode 113a also extends spirally along the axial direction of the substrate 110, and the height of the spiral extension is the same as the length of the infrared electrothermal coating 111 extending along the axial direction of the substrate 110; the connection electrode 113a divides the infrared electrothermal coating 111 into 2 sub-infrared electrothermal coatings (shown as A1 and A2 in the figure) connected in series between the conductive electrode 112a and the conductive electrode 112 b.
After the heater 11 is energized, for example, the conductive electrode 112a is electrically connected to the positive electrode of the power supply, the conductive electrode 112b is electrically connected to the negative electrode of the power supply, and the current flows from the conductive electrode 112a, sequentially through the sub-infrared electrothermal coating A1 and the sub-infrared electrothermal coating A2, and then flows from the conductive electrode 112 b.
It should be noted that, in fig. 7, the conductive electrode 112c is added to achieve the staged heating of the aerosol-forming substrate, and the same applies to the heaters of fig. 3 to 4 and 8. It will be appreciated that multi-stage heating may be achieved by a plurality of conductive electrodes.
Fig. 9 to 10 are views showing a fifth heater according to an embodiment of the present application.
Unlike fig. 3-4, the infrared electrothermal coating 111 includes two infrared electrothermal coatings disposed at intervals, which are shown as infrared electrothermal coating 111a and infrared electrothermal coating 111 b. Wherein the infrared electrothermal coating 111a is closer to the mouth end of the aerosol-generating device 100 than the infrared electrothermal coating 111 b. The distance between the infrared electrothermal coating 111a and the infrared electrothermal coating 111b is 0.2 mm-1 mm.
The conductive electrode 112a includes a coupling portion 112a1 extending in the circumferential direction of the base 110 and a conductive portion 112a2 extending axially from the coupling portion 112a1 toward the upper end of the base 110. The coupling portion 112a1 is arc-shaped, the coupling portion 112a1 and the infrared electrothermal coating 111b are arranged at intervals, and the coupling portion 112a1 is arranged between the infrared electrothermal coating 111b and the lower end of the substrate 110; wires may be soldered to the coupling portion 112a1 to form an electrical connection with a power source external to the heater 11, such as the battery cell 7 or a voltage converted by the battery cell 7, or may be electrically connected with the power source through other electrical connectors. The conductive part 112a2 is in a strip shape, the axially extending length is longer than that of the infrared electrothermal coating 111b, and the upper end of the conductive part 112a2 is flush with the upper end of the infrared electrothermal coating 111 b; the conductive portion 112a2 is held in contact with the infrared electrothermal coating 111b to form an electrical connection.
The conductive electrode 112b has a bar shape, and its axially extending length is the same as that of the infrared electrothermal coating 111 a. The conductive electrode 112b is held in contact with the infrared electrothermal coating 111a to form an electrical connection.
The conductive electrode 112c is similar in structure to the conductive electrode 112 a. The coupling portion 112c1 of the conductive electrode 112c is disposed between the infrared electrothermal coating 111b and the lower end of the substrate 110, and the conductive portion 112c2 is in a strip shape, but its axially extending length is greater than the sum of the axially extending lengths of the infrared electrothermal coating 111a and the infrared electrothermal coating 111b, and the upper end of the conductive portion 112c2 is flush with the upper end of the infrared electrothermal coating 111 a. The conductive portion 112c2 is in contact with both the infrared electrothermal coating 111a and the infrared electrothermal coating 111b to form an electrical connection.
The connection electrode 113a and the connection electrode 113b are each in a bar shape and are provided in the infrared electrothermal coating 111 b. The axial extension length of the connection electrode 113a and the connection electrode 113b is the same as the axial extension length of the infrared electrothermal coating 111 b.
The connection electrode 113a is disposed between the conductive electrode 112a and the conductive electrode 112c. The connection electrode 113a separates the infrared electrothermal coating between the conductive electrode 112a and the conductive electrode 112c into two sub-infrared electrothermal coatings (shown as B1 and B2 in fig. 10) connected in series between the conductive electrode 112a and the conductive electrode 112c, and the sub-infrared electrothermal coatings B1 and B2 are distributed along the circumferential direction of the substrate 110; the equivalent resistance of the sub-infrared electrothermal coating B1 and the equivalent resistance of the sub-infrared electrothermal coating B2 can be the same or different.
The connection electrode 113b is also provided between the conductive electrode 112a and the conductive electrode 112c. The connection electrode 113B separates the infrared electrothermal coating between the conductive electrode 112a and the conductive electrode 112c into two sub-infrared electrothermal coatings (shown as B3 and B4 in fig. 10) connected in series between the conductive electrode 112a and the conductive electrode 112c, and the sub-infrared electrothermal coatings B3 and B4 are distributed along the circumferential direction of the substrate 110; the equivalent resistance of the sub-infrared electrothermal coating B3 and the equivalent resistance of the sub-infrared electrothermal coating B4 can be the same or different.
By providing the connection electrode 113a and the connection electrode 113b, the overall resistance value of the infrared electrothermal coating 111b can be reduced.
Similar to fig. 7 or 8, the infrared electrothermal coating 111a and the infrared electrothermal coating 111b are independently controllable by the conductive element arrangement in fig. 9. Specifically, the power supply may be controlled to provide heating power to the infrared electrothermal coating 111a and/or the infrared electrothermal coating 111 b; for example, the power supply is controlled to provide heating power to the infrared electrothermal coating 111a to heat the upper half of the aerosol-generating article (the portion corresponding to the region of the infrared electrothermal coating 111 a); the power supply is then controlled to provide heating power to the infrared electrothermal coating 111b to heat the lower half of the aerosol-generating article (the portion corresponding to the region of the infrared electrothermal coating 111 b). Vice versa.
Alternatively, the power supply is controlled to provide heating power to the infrared electrothermal coating 111a to heat the upper half of the aerosol-generating article; the power supply is then controlled to simultaneously provide heating power to the infrared electrothermal coating 111a and the infrared electrothermal coating 111b to heat the entire aerosol-generating article.
Alternatively, the power supply is controlled to provide heating power to the infrared electrothermal coating 111b to heat the lower half of the aerosol-generating article; the power supply is then controlled to simultaneously provide heating power to the infrared electrothermal coating 111a and the infrared electrothermal coating 111b to heat the entire aerosol-generating article.
When the infrared electrothermal coating 111a is controlled to be heated, for example, the conductive electrode 112b is electrically connected to the positive electrode of the power supply, and the coupling portion 112c1 is electrically connected to the negative electrode of the power supply; thus, the current flows from the conductive electrode 112b, passes through the sub-infrared electrothermal coating A1 or the sub-infrared electrothermal coating A2 along the circumferential direction of the base 110, and then flows out from the conductive portion 112c 2.
When the infrared electrothermal coating 111B is controlled to be heated, for example, the coupling portion 112a1 is electrically connected to the positive electrode of the power supply, the coupling portion 112c1 is electrically connected to the negative electrode of the power supply, and current flows in from the conductive portion 112a2, sequentially passes through the infrared electrothermal coating B1 and the infrared electrothermal coating B2, or sequentially passes through the infrared electrothermal coating B4 and the infrared electrothermal coating B3, and then flows out from the conductive portion 112c 2. The connection electrode 113a and the connection electrode 113b are not connected to a power source or a circuit outside the heater 11, that is, the connection electrode 113a and the connection electrode 113b are suspended, and current cannot directly flow in from the connection electrode 113a and then flow out from the conductive portion 112b2 or the conductive portion 112a2. The presence of the connection electrode 113a and the connection electrode 113b can reduce the overall resistance of the infrared electrothermal coating 111 b.
Fig. 11-12 are sixth heaters provided in embodiments of the present application.
Unlike fig. 9-10, the conductive portion 112a2 of the conductive electrode 112a has an axially extending length greater than the sum of the axially extending lengths of the infrared electrothermal coating 111a and the infrared electrothermal coating 111b, and the upper end of the conductive portion 112a2 is flush with the upper end of the infrared electrothermal coating 111 a. The conductive portion 112a2 is held in contact with both the infrared electrothermal coating 111a and the infrared electrothermal coating 111b to form an electrical connection. Conductive electrode 112b and conductive electrode 112d are both disposed in the region of infrared electrothermal coating 111a and remain in contact with infrared electrothermal coating 111a to form an electrical connection. The conductive electrode 112b, the conductive portion 112a2, the conductive electrode 112d, and the conductive portion 112c2 are sequentially arranged at intervals along the circumferential direction of the base 110.
Unlike fig. 9-10, infrared electrothermal coating 111a is independently controllable, while infrared electrothermal coating 111b is not.
When controlling the heater 11 to heat, firstly, a control power supply supplies heating power to the infrared electrothermal coating 111a through the conductive electrode 112b and the conductive electrode 112 d; then, the power supply is controlled to simultaneously supply heating power to the infrared electrothermal coating 111a and the infrared electrothermal coating 111b through the conductive electrode 112a and the conductive electrode 112c.
When the conductive electrode 112b and the conductive electrode 112d are energized, the conductive portion (the conductive portion 112a2 of the conductive electrode 112a and the conductive portion 112c2 of the conductive electrode 112 c) between the conductive electrode 112b and the conductive electrode 112d is not energized, which corresponds to the connection electrode in the examples of fig. 9-10, and further reduces the overall resistance of the infrared electrothermal coating 111a, so that the infrared electrothermal coating 111a is heated up quickly, and the upper half of the aerosol-generating article can be heated up quickly, thereby achieving the purpose of generating aerosol quickly.
When the conductive electrode 112a and the conductive electrode 112c are energized, the conductive electrode 112b and the conductive electrode 112d between the conductive electrode 112a and the conductive electrode 112c are not energized, which is also equivalent to the connection electrode in the examples of fig. 9 to 10, thereby reducing the overall resistance value of the infrared electrothermal coating 111 a. At this time, since the infrared electrothermal coating 111a and the infrared electrothermal coating 111b are heated simultaneously or the infrared electrothermal coating 111 is heated integrally, the overall resistance of the infrared electrothermal coating 111a is reduced due to the conductive electrode 112b and the conductive electrode 112d, so that the temperature of the infrared electrothermal coating 111a region is increased, and the temperature field of the whole infrared electrothermal coating 111 region is changed.
