Alternatively, the base 11 is in the form of a hollow tube, the interior of which forms a receiving cavity 111, the aerosol-generating article being removably received in the receiving cavity 111; in the following examples, the substrate 11 is in the form of a hollow tube. Specifically, the substrate 11 may be made of an infrared-transmitting insulating material, such as quartz glass, ceramic, mica, and other high-temperature-resistant and transparent insulating materials.
An infrared heat generating layer 20 is provided on the base 11 for radiating infrared light when energised to heat the aerosol generating article. In one embodiment, the infrared heat generating layer 20 is disposed around the entire outer surface of the substrate 11 and between the first electrode 301 and the second electrode 302 to radiate infrared rays when energized, thereby utilizing the high penetration characteristics of infrared rays to heat and atomize the aerosol-generating article contained in the substrate 11 to form an aerosol. Wherein, because infrared ray's heat radiation ability is stronger for infrared ray can penetrate the inside that aerosol generated the goods and heat its whole simultaneously, compare in conventional resistance-type heating methods or electromagnetic type heating methods, this mode has improved heating efficiency, and the heating homogeneity is better, has avoided leading to aerosol to generate the problem that the goods is burnt because of local high temperature, has guaranteed sufficient fog volume and better suction experience.

It can be understood that the infrared heat-generating layer 20 has a uniform thickness throughout the base 11 in order to make the heating effect thereof more uniform. In this embodiment, the infrared heat generating layer 20 is an infrared ceramic coating, and the infrared heat generating layer 20 radiates infrared light when energized to heat the aerosol generating article. The infrared heating wavelength is 2.5um ~ 20um, and to the characteristics of heating aerosol generation goods, the heating temperature needs more than 350 ℃ usually, and the energy radiation extremum is mainly in 3 ~ 5um wave band.
In other embodiments, the infrared heating layer 20 may also be disposed on the inner surface of the base 11, and extend along the axial direction of the base 11, and the shape, thickness and area of the infrared heating layer may be set as required; the materials and the manufacturing process of the infrared heating layer 20 are the materials and the manufacturing process in the above embodiments, and are not described herein again.
The first electrode 301 and the second electrode 302 are disposed on the surface of the substrate 11, and are disposed opposite to each other along the radial direction of the substrate 11, and are respectively in contact with the infrared heating layer 20, so as to achieve electrical connection with the infrared heating layer 20. In a specific embodiment, the first electrode 301 and the second electrode 302 are used to electrically connect with the battery assembly 21 to supply power to the infrared heat generating layer 20 and the first conductive module 303. Of course, in other embodiments, the first electrode 301 and the second electrode 302 may also be disposed on a side surface of the infrared heating layer 20 away from the base 11, which facilitates processing and reduces processing difficulty. The first electrode 301 and the second electrode 302 are disposed on the surface of the substrate 11, and may be disposed on the outer surface or the inner surface of the substrate 11, and the shape, size, thickness, and the like of the electrodes may be set as needed, which is not particularly limited in the present application.
Specifically, the first electrode 301 and the second electrode 302 may be in a strip shape and parallel to each other. The first electrode 301 and the second electrode 302 may be specifically conductive coatings or conductive sheets, and the shape, size and thickness thereof may be set as required.
The first conductive module 303 is disposed on the surface of the base 11 and electrically connected to the first electrode 301 and the second electrode 302, and at least a portion of the first conductive module 303 is in contact with the infrared heating layer 20, so that the first conductive module 303 and the infrared heating layer 20 in the contact area thereof are connected in parallel, and the first conductive module 303 can be directly connected to the first electrode 301 and the second electrode 302 without strictly being disposed between the first conductive module 303 and the first electrode 301 or a space being reserved between the first conductive module 303 and the second electrode 302, so that the structure is simpler and the manufacturing process can be effectively simplified.
The area of the heating assembly 1 corresponding to the contact between the first conductive module 303 and the infrared heating layer 20 is defined as a high-resistance conductive module area. It should be noted that at least a portion of the first conductive module 303 is in contact with the infrared heating layer 20, and may be in stacked contact, or the first conductive module 303 and the infrared heating layer 20 are disposed on the same layer on the base 11 and are in contact, which may be specifically disposed as needed, and this is not limited.
Further, after the heating assembly 1 is powered on, when the heating assembly is powered on for a first time period, the difference between the resistivities of the first conductive module 303 and the infrared heating layer 20 is a first difference; when the power is switched on for the second time length, the difference value of the resistivities of the first conductive module 303 and the infrared heating layer 20 is a second difference value; wherein the first difference is different from the second difference. That is, there are at least two different time nodes during the power-on process, and the difference between the resistivities of the first conductive module 303 and the infrared heat-generating layer 20 is different, that is, the difference between the resistivities of the first conductive module 303 and the infrared heat-generating layer 20 changes with the change of the power-on time.
In a specific embodiment, the relation between the resistivity of the first conductive module 303 and the resistivity of the infrared heating layer 20 may be that the resistivity of the first conductive module 303 is different from the resistivity of the infrared heating layer 20 before being electrified, and after being electrified for a certain time, the resistivity of the first conductive module 303 and the resistivity of the infrared heating layer 20 gradually tend to be the same. The resistivity of the first conductive module 303 and the resistivity of the infrared heating layer 20 may be the same before the energization, after the energization is performed for a certain time, the resistivity of the first conductive module 303 and the resistivity of the infrared heating layer 20 gradually tend to be different, and the difference between the two may gradually become smaller or larger. Therefore, the power density of the high-resistance conductive module area of the heating assembly 1 at different power-on time nodes is different from the power density of the infrared heating layer 20 in the rest areas, and the heating efficiency is also different, so that the corresponding first conductive modules 303 can be arranged in different areas on the heating assembly 1 to meet the requirements of different temperature fields.
In a specific embodiment, in a non-energized state of the heating assembly 1, the first conductive module 303 has a different resistivity than the infrared heat generating layer 20; so set up for heating element 1 circular telegram back, at the initial stage of heating, the power that the infrared layer 20 that generates heat of part department that contacts with first conductive module 303 is different with the power of the infrared layer 20 that generates heat of other regions, and the power of high resistance conductive module district is different with the power of the infrared layer 20 that generates heat of other regions promptly, and then its corresponding temperature is also different, in order to realize that control different regions has different temperatures.
Specifically, in the non-energized state of the heating assembly 1, the resistivity of the first conductive module is smaller than that of the infrared heating layer; so set up for heating element 1 circular telegram back, at the initial stage of heating, the power that the infrared layer 20 that generates heat of the part department that contacts with first conductive module 303 is greater than the power of the infrared layer 20 that generates heat of all the other regions, thereby makes the temperature rise in this region faster, and the intensity of the infrared ray of sending is higher, and the aerosol generates the position temperature rise that corresponds with the high resistance conductive module district on the goods faster, is sufficient with the play fog volume of guaranteeing the initial stage of heating.
In a specific embodiment, the resistivity of the high-resistance conductive module area of the heating assembly 1 may be slightly smaller than the resistivity of the infrared heating layer 20 in other areas, so that the power density of the high-resistance conductive module area is not too large compared with the power density of the infrared heating layer 20 in other areas, and thus the fine adjustment of the temperature field of the high-resistance conductive module area is realized, the temperature adjustment is relatively mild, and the problem of shortening of the service time of aerosol-generating products due to too much mist output in the initial heating stage is avoided.
Of course, in other embodiments, in the non-energized state of the heating assembly 1, the resistivity of the first conductive module 303 is greater than the resistivity of the infrared heat generation layer 20; so set up for heating element 1 circular telegram back, in the initial stage of heating, the power that the infrared layer 20 that generates heat of the part department that contacts with first electrically conductive module 303 is less than the power of the infrared layer 20 that generates heat of other regions, thereby makes the temperature rise of these other regions faster, and the intensity of the infrared ray of sending is higher, and the position temperature rise that corresponds with this region on the aerosol generating product is faster, in order to guarantee that the play fog volume of heating initial stage is sufficient.
In one embodiment, referring to fig. 2a, fig. 2a is a sectional view taken along line a-a of fig. 1; at least part of the infrared heating layer 20 is positioned between the base body 11 and the first conductive module 303; namely, the first conductive module 303 is formed on the surface of the infrared heating layer 20 facing away from the base 11. In another embodiment, referring to fig. 2b, at least a portion of the infrared heating layer 20 is located on a side surface of the first conductive module 303 facing away from the base 11; namely, the first conductive module 303 is disposed on the surface of the base 11, a part of the infrared heating layer 20 covers the first conductive module 303, and the rest is disposed on the surface of the base 11. Or, the infrared heating layer 20 and the first conductive module 303 are disposed on the same layer of the surface of the base 11, and at least part of the infrared heating layer and the first conductive module are in contact with each other. The relative position of the infrared heating layer 20 and the first conductive module 303 on the base body 11 is more flexible, and the infrared heating layer and the first conductive module can be selected according to the manufacturing process or other requirements.
The first conductive module 303 may be disposed at a preset position of the heating assembly 1 as required to form a high temperature region with a rapid temperature rise at the preset position, so that the aerosol generating product corresponding to the high temperature region is rapidly atomized to ensure an amount of mist generated at an initial heating stage. Wherein the predetermined position may be a position away from a mouthpiece of the aerosol-generating device to prevent the problem of nozzle burning due to excessive temperature; of course, any other location remote from the mouthpiece is possible; the specific setting can be made according to the actual situation.
Further, the first conductive module 303 has a Positive Temperature Coefficient (PTC) characteristic, and is made of a material having a Positive Temperature Coefficient (PTC) characteristic, and specifically, the PTC material having a corresponding temperature coefficient and a curie temperature can be selected as required; such as barium titanate semiconductive ceramic, high molecular weight polymeric materials, and the like. The curie temperature is a temperature at which the resistance value starts to increase stepwise. The positive temperature coefficient characteristic of the first conductive module 303 makes the infrared heating layer 20 in the region contacting with the first conductive module form a parallel circuit with the first conductive module, so that the parallel resistance of the region corresponding to the heating component 1 is smaller than the resistance of other regions, the current flowing through the infrared heating layer 20 in the region is larger, the power density is larger, and the temperature rise of the region is faster than that of other regions; when the resistance of the first conductive module 303 gradually increases with the increase of the temperature, the total resistance value of the area after the parallel connection also gradually increases, so that the current flowing through the infrared heating layer 20 in the area tends to be consistent with the current flowing through the infrared heating layer 20 in other areas, and then the power density also tends to be consistent, thereby achieving the effect of uniformly heating the aerosol generating product.
In the specific embodiment, since the first conductive module 303 has the PTC characteristic, the heating assembly 1 can also realize the temperature measurement function of the heating assembly 1 by monitoring the resistance value of the first conductive module 303, so as to regulate and control the temperature field of the heating assembly 1, thereby achieving the best atomization effect of the aerosol-generating product, and no additional thermocouple or other temperature measurement element is required, thereby further simplifying the structure.
Specifically, the first conductive module 303 is integrally formed with the first electrode 301 and the second electrode 302, or the first conductive module 303 is integrally formed with one of the first electrode 301 and the second electrode 302; so as to facilitate the preparation. Specifically, the first conductive module 303 may be formed on the substrate 11 together with the first electrode 301 and the second electrode 302 by coating, silk-screening, sputtering, or printing, or the first conductive module 303 and one of the first electrode 301 and the second electrode 302 may be formed on the substrate 11 by the same method. Wherein, part of the infrared heating layer 20 is disposed between the base 11 and the first and second electrodes 301 and 302 and the first conductive module 303, or part of the infrared heating layer 20 is disposed on one side surface of the first and second electrodes 301 and 302 and the first conductive module 303, which faces away from the base 11.
Further, the first conductive module 303 has at least two different positions along the extending direction, and the cross-sectional areas of the at least two different positions are different; when the power is turned on and heated, the resistance values of different areas of the first conductive module 303 along the extension direction are different, so that the temperatures of the first conductive module 303 are different, and the temperature in a local area can be accurately adjusted; the cross-sectional area at different positions can be set according to the needs, and is not particularly limited.

In this embodiment, the overall extension direction B of the first conductive module 303 is perpendicular to the extension directions of the first electrode 301 and the second electrode 302, respectively. Of course, in other embodiments, the angle between the overall extension direction B of the wave-shaped first conductive module 303 and the extension directions of the first electrode 301 and the second electrode 302 may also be between 0 ° and 90 ° or between 90 ° and 180 °, excluding 0 ° and 180 °. The angle may specifically be set as required by the temperature field of the corresponding region on the heating assembly 1, so that the corresponding region of the heating assembly 1 may be pre-set with the required temperature field to achieve optimal atomisation when heating the aerosol-generating article.
In the case that the linear distance between the first electrode 301 and the second electrode 302 is equal, and the cross-sectional area and the resistivity of the first conductive module 303 are the same, the total length of the curve of the wave-shaped first conductive module 303 is greater than the total length of the straight line of the linear first conductive module 303 corresponding to fig. 3, according to the formula: r (resistance) ═ ρ (resistivity) L (wire length)/S (wire cross-sectional area); it can be known that, compared to the straight-line first conductive module 303 in fig. 3, the resistance of the first conductive module 303 corresponding to fig. 4 is larger, and the total resistance of the high-resistance conductive module area in the embodiment corresponding to fig. 4 is larger than that of the high-resistance conductive module area in the embodiment corresponding to fig. 3, so that the heating rate of the high-resistance conductive module area in the embodiment corresponding to fig. 4 is smaller than the power density of the high-resistance conductive module area in the embodiment corresponding to fig. 3, and the temperature field of the heating assembly 1 can be further fine-tuned according to actual requirements.
Specifically, the cross-sectional area of the first conductive module 303 is smaller than the cross-sectional area of the first electrode 301; or the cross-sectional area of the first conductive module 303 is smaller than the cross-sectional area of the second electrode 302; or the cross-sectional area of the first conductive module 303 is smaller than the cross-sectional area of the first electrode 301 and smaller than the cross-sectional area of the second electrode 302. Therefore, the resistance of the first conductive module 303 is larger than the resistance of the first electrode 301 and/or the second electrode 302, and the first conductive module 303 does not short-circuit the first electrode 301 and the second electrode 302 when the first electrode 301 and the second electrode 302 are electrically connected with the positive electrode and the negative electrode of the power supply respectively. It will be appreciated that in particular embodiments, the location of the first conductive module 303 and its cross-sectional area may be specifically configured according to the area of the heating assembly 1 that needs to be rapidly warmed up and the temperature field requirements of that area.
In a specific embodiment, the thicknesses of the first electrode 301, the second electrode 302 and the first conductive module 303 are generally smaller and substantially the same, so that the larger the cross-sectional area is, the larger the width is; therefore, the cross-sectional area of the first conductive module 303 is smaller than the cross-sectional area of the first electrode 301, or the cross-sectional area of the first conductive module 303 is smaller than the cross-sectional area of the second electrode 302, or the cross-sectional area of the first conductive module 303 is smaller than the cross-sectional area of the first electrode 301 and smaller than the cross-sectional area of the second electrode 302; it is understood that the width of the first conductive module 303 is smaller than the width of the first electrode 301, or the width of the first conductive module 303 is smaller than the width of the second electrode 302, or the width of the first conductive module 303 is smaller than the width of the first electrode 301 and smaller than the width of the second electrode 302.

It is easy to understand that, if the cross-sectional areas of the first conductive modules 303 are different, the resistance values thereof are different, and the total resistances thereof in the corresponding areas of the heating assembly 1 are also different, so that the power densities of the first conductive modules 303 with different cross-sectional areas in the corresponding areas of the heating assembly 1 are also different, and the heating rates of the corresponding areas are different, that is, a plurality of different temperature fields are correspondingly formed; therefore, the first conductive module 303 with a large cross section area can be arranged at a position corresponding to a region needing rapid temperature rise, and the first conductive module with a slightly smaller cross section area is arranged at a position corresponding to an adjacent region, so that the adjacent region of the heating assembly 1 can realize temperature gradient decrease or increase, and the heating requirements of more kinds of aerosol generating products can be met by enriching the temperature distribution mode of a temperature field.
