在具体实施例中,第一导电模块303与红外发热层20的电阻率的关系,可以是第一导电模块303的电阻率与红外发热层20的电阻率在通电前不同,通电一定时间后,第一导电模块303的电阻率与红外发热层20的电阻率逐渐趋于相同。也可以是第一导电模块303的电阻率与红外发热层20的电阻率在通电前相同,通电一定时间后,第一导电模块303的电阻率与红外发热层20的电阻率逐渐趋于不同,二者的差值可逐渐变小或逐渐变大。因此,加热组件1的高阻导电模块区在不同的通电时间节点的功率密度,与其余区域的红外发热层20的功率密度之间的差值不同,加热效率也不同,据此可对加热组件1上不同区域设置对应的第一导电模块303,以满足 不同的温度场的需要。In a specific embodiment, the relationship between the resistivity of the first conductive module 303 and the infrared heating layer 20 can be that the resistivity of the first conductive module 303 and the resistivity of the infrared heating layer 20 are different before power is supplied, and after a certain period of time, The resistivity of the first conductive module 303 gradually becomes the same as the resistivity of the infrared heating layer 20 . It is also possible that the resistivity of the first conductive module 303 and the resistivity of the infrared heating layer 20 are the same before power is turned on. After a certain period of time, the resistivity of the first conductive module 303 and the resistivity of the infrared heating layer 20 gradually tend to be different. The difference between the two can gradually become smaller or larger. Therefore, the difference between the power density of the high-resistance conductive module area of the heating component 1 at different power-on time nodes and the power density of the infrared heating layer 20 in the remaining areas is different, and the heating efficiency is also different. Based on this, the heating component can be Corresponding first conductive modules 303 are provided in different areas on 1 to meet the needs of different temperature fields.
在具体实施例中,在加热组件1未通电状态下,第一导电模块303与红外发热层20的电阻率不同;如此设置,使得加热组件1通电后,在加热初始阶段,与第一导电模块303相接触的部分红外发热层20处的功率与其他区域红外发热层20的功率不同,即高阻导电模块区的功率与其他区域的红外发热层20的功率不同,则其对应的温度也不同,以实现控制不同区域具有不同的温度。In a specific embodiment, when the heating component 1 is not energized, the resistivities of the first conductive module 303 and the infrared heating layer 20 are different; this arrangement is such that after the heating component 1 is energized, in the initial stage of heating, the resistivities of the first conductive module 303 and the infrared heating layer 20 are different. The power at the part of the infrared heating layer 20 in contact with 303 is different from the power of the infrared heating layer 20 in other areas. That is, the power in the high-resistance conductive module area is different from the power of the infrared heating layer 20 in other areas, so the corresponding temperatures are also different. , to achieve control of different temperatures in different areas.
具体地,在加热组件1未通电状态下,第一导电模块的电阻率小于红外发热层的电阻率;如此设置,使得加热组件1通电后,在加热初始阶段,与第一导电模块303相接触的部分红外发热层20处的功率大于其余区域的红外发热层20的功率,从而使得该区域的温升更快,发出的红外线的强度更高,气溶胶生成制品上与高阻导电模块区对应的位置升温较快,以保证加热初始阶段的出雾量充足。Specifically, when the heating component 1 is not energized, the resistivity of the first conductive module is smaller than the resistivity of the infrared heating layer; this setting is such that after the heating component 1 is energized, it contacts the first conductive module 303 in the initial stage of heating. The power of some infrared heating layers 20 is greater than the power of the infrared heating layers 20 in other areas, so that the temperature in this area rises faster and the intensity of the infrared rays emitted is higher. The aerosol-generating product corresponds to the high-resistance conductive module area. The position heats up quickly to ensure sufficient mist output in the initial stage of heating.
在具体实施例中,加热组件1的高阻导电模块区的电阻率可略小于其他区域红外发热层20的电阻率,这样可以使得高阻导电模块区的功率密度与其他区域红外发热层20的功率密度相比不会过大,从而实现对该高阻导电模块区温度场的微调,使得温度调节相对更加温和,避免出现加热初始阶段出雾量过多而导致气溶胶生成制品的使用时间缩短的问题。In a specific embodiment, the resistivity of the high-resistance conductive module area of the heating component 1 can be slightly smaller than the resistivity of the infrared heating layer 20 in other areas. This can make the power density of the high-resistance conductive module area consistent with that of the infrared heating layer 20 in other areas. The power density will not be too large, thereby achieving fine-tuning of the temperature field in the high-resistance conductive module area, making the temperature adjustment relatively gentle, and avoiding excessive fogging in the initial stage of heating, which will shorten the use time of aerosol-generating products. The problem.
当然,在其他实施例中,在加热组件1未通电状态下,第一导电模块303的电阻率大于红外发热层20的电阻率;如此设置,使得加热组件1通电后,在加热初始阶段,与第一导电模块303相接触的部分红外发热层20处的功率小于其余区域的红外发热层20的功率,从而使得该其余区域的温升更快,发出的红外线的强度更高,气溶胶生成制品上与该区域对应的位置升温较快,以保证加热初始阶段的出雾量充足。Of course, in other embodiments, when the heating component 1 is not energized, the resistivity of the first conductive module 303 is greater than the resistivity of the infrared heating layer 20; such an arrangement makes the heating component 1, in the initial stage of heating, and The power at the part of the infrared heating layer 20 in contact with the first conductive module 303 is less than the power of the infrared heating layer 20 in the remaining areas, so that the temperature of the remaining areas rises faster and the intensity of the emitted infrared rays is higher, and the aerosol-generating product The position corresponding to this area heats up quickly to ensure sufficient mist output in the initial stage of heating.
在一具体实施例中,请参见图2a,图2a为图1的A-A向剖视图;红外发热层20的至少部分位于基体11和第一导电模块303之间;即第一导电模块303形成于红外发热层20背离基体11的一侧表面。在另一实施例中,请参见图2b,红外发热层20的至少部分位于第一导电模块303背离基体11的一侧表面;即第一导电模块303设置于基体11的表面,红外发热层20的部分覆盖第一导电模块303,其余部分设置于基体11的表面。或者,红外发热层20与第一导电模块303设置于基体11表面的同一层,且至少部分相互接触。本申请提供的红外发热层20与第一导电模块303在基体11上的相对位置更加灵活,具体可根据制作工艺或其他需要进行选择。In a specific embodiment, please refer to Figure 2a, which is a cross-sectional view along A-A in Figure 1; at least part of the infrared heating layer 20 is located between the base 11 and the first conductive module 303; that is, the first conductive module 303 is formed on the infrared The heating layer 20 has a side surface facing away from the base 11 . In another embodiment, please refer to Figure 2b. At least part of the infrared heating layer 20 is located on the side surface of the first conductive module 303 facing away from the base 11; that is, the first conductive module 303 is disposed on the surface of the base 11, and the infrared heating layer 20 part covers the first conductive module 303 , and the remaining part is disposed on the surface of the base 11 . Alternatively, the infrared heating layer 20 and the first conductive module 303 are disposed on the same layer on the surface of the base 11 and are at least partially in contact with each other. The relative positions of the infrared heating layer 20 and the first conductive module 303 provided in this application on the base 11 are more flexible, and can be selected according to the manufacturing process or other needs.
其中,第一导电模块303具体可根据需要设置于加热组件1的预设位置,以在该预设位置形成快速升温的高温区域,使该高温区域对应的气溶胶生成制品快速雾化,以保证加热初期的出雾量。其中,预设位置可为远离气溶胶生成装置的吸嘴的位置,以防温度过高出现烫嘴问题;当然,也可为远离吸嘴的任意其它位置;具体 可根据实际进行设定。Among them, the first conductive module 303 can be set at a preset position of the heating component 1 as needed to form a high-temperature area that rapidly heats up at the preset position, so that the aerosol-generating product corresponding to the high-temperature area can be quickly atomized to ensure that The amount of mist produced at the initial stage of heating. Among them, the preset position can be a position far away from the suction nozzle of the aerosol generating device to prevent the problem of burning the mouth due to excessive temperature; of course, it can also be any other position far away from the suction nozzle; the specific setting can be based on actual conditions.
进一步地,第一导电模块303具有正的温度系数(PTC)特性,采用具有正的温度系数(PTC)特性的材料制成,具体可根据需要进行选择相应温度系数和居里温度的PTC材料;比如钛酸钡半导体陶瓷、高分子聚合物材料等。其中,居里温度是指电阻值开始阶跃性地增高时的温度。第一导电模块303的正的温度系数特性,使得与其接触的区域的红外发热层20与之形成并联线路,则对应加热组件1上的该区域的并联电阻相较于其他区域的电阻要小,流经该区域的红外发热层20的电流较大,功率密度较大,故该区域升温相较于其他区域较快;当第一导电模块303的电阻随温度升高而逐渐增大,该区域并联后的总阻值也逐渐增大,使得流经该区域红外发热层20的电流与流经其他区域的红外发热层20的电流趋于一致,则功率密度也趋于一致,从而达到对气溶胶生成制品均匀加热的效果。Further, the first conductive module 303 has a positive temperature coefficient (PTC) characteristic and is made of a material with a positive temperature coefficient (PTC) characteristic. Specifically, a PTC material with a corresponding temperature coefficient and Curie temperature can be selected as needed; For example, barium titanate semiconductor ceramics, high molecular polymer materials, etc. Among them, Curie temperature refers to the temperature when the resistance value begins to increase stepwise. The positive temperature coefficient characteristic of the first conductive module 303 causes the infrared heating layer 20 in the area in contact with it to form a parallel circuit, so the parallel resistance of this area on the corresponding heating component 1 is smaller than the resistance of other areas. The current flowing through the infrared heating layer 20 in this area is larger and the power density is larger, so the temperature in this area heats up faster than other areas; when the resistance of the first conductive module 303 gradually increases with the increase in temperature, this area The total resistance after parallel connection also gradually increases, so that the current flowing through the infrared heating layer 20 in this area tends to be consistent with the current flowing through the infrared heating layer 20 in other areas, and the power density also tends to be consistent, thereby achieving the goal of air protection. The sol generates a uniform heating effect on the product.
在具体实施例中,由于第一导电模块303具有PTC特性,使得加热组件1还可通过监测第一导电模块303的阻值实现加热组件1的测温功能,进而调控加热组件1的温度场,以达到气溶胶生成制品的最佳雾化效果,且无需额外增加热电偶以及其他测温元件,进一步简化结构。In a specific embodiment, since the first conductive module 303 has PTC characteristics, the heating component 1 can also realize the temperature measurement function of the heating component 1 by monitoring the resistance of the first conductive module 303, thereby regulating the temperature field of the heating component 1. In order to achieve the best atomization effect of aerosol-generating products, there is no need to add additional thermocouples and other temperature measurement components, further simplifying the structure.

As a result, the temperatures are also different to achieve precise temperature adjustment in local areas; the cross-sectional areas at different locations can be set according to needs, and there are no specific restrictions on this.
在一实施例中,请参见图3,图3为本申请第一实施例提供的第一导电模块与第一电极和第二电极以及红外发热层展开后的结构示意图。第一电极301、第二电极302和第一导电模块303均可呈长条形,即直线型。其中第一电极301与第二电极302相互平行,第一导电模块303设置于第一电极301与第二电极302之间,且从第一电极301延伸至第二电极302。具体的,第一导电模块303的延伸方向垂直于第一电极301和第二电极302的延伸方向。In one embodiment, please refer to FIG. 3 , which is a schematic structural diagram of the first conductive module, the first electrode, the second electrode, and the infrared heating layer provided in the first embodiment of the present application after unfolding. The first electrode 301, the second electrode 302 and the first conductive module 303 can all be in a long strip shape, that is, a linear shape. The first electrode 301 and the second electrode 302 are parallel to each other, and the first conductive module 303 is disposed between the first electrode 301 and the second electrode 302 and extends from the first electrode 301 to the second electrode 302 . Specifically, the extension direction of the first conductive module 303 is perpendicular to the extension directions of the first electrode 301 and the second electrode 302 .
在其他实施例中,第一导电模块303的延伸方向与第一电极301和第二电极302 的延伸方向所成的角也可在0°~90°之间或90°~180°之间,不包括0°和180°。具体可根据加热组件1上相应区域的温度场的需要来设定该角度,使得加热组件1相应的区域可以预设需要的温度场,在加热气溶胶生成制品时已达到最佳雾化效果。In other embodiments, the angle formed by the extending direction of the first conductive module 303 and the extending directions of the first electrode 301 and the second electrode 302 may also be between 0°˜90° or between 90°˜180°, or Includes 0° and 180°. Specifically, the angle can be set according to the needs of the temperature field of the corresponding area on the heating component 1, so that the corresponding area of the heating component 1 can preset the required temperature field, and the best atomization effect can be achieved when heating the aerosol to generate the product.
在另一实施例中,请参见图4,图4为本申请第二实施例提供的第一导电模块与第一电极和第二电极以及红外发热层展开后的结构示意图。第一电极301与第二电极302呈长条形且相互平行,第一导电模块303设置于第一电极301与第二电极302之间且从第一电极301延伸至第二电极302,且第一导电模块303具体呈曲线型,也可以理解为呈波浪型。在该具体实施例中,第一导电模块303的整体延伸走向B分别与第一电极301和第二电极302的延伸方向垂直。当然,在其他实施例中,波浪型的第一导电模块303的整体延伸走向B与第一电极301和第二电极302的延伸方向所成的角也可在0°~90°之间或90°~180°之间,不包括0°和180°。具体可根据加热组件1上相应区域的温度场的需要来设定该角度,使得加热组件1相应的区域可以预设需要的温度场,在加热气溶胶生成制品时已达到最佳雾化效果。In another embodiment, please refer to FIG. 4 , which is a schematic structural diagram of the first conductive module, the first electrode, the second electrode, and the infrared heating layer provided in the second embodiment of the present application after unfolding. The first electrode 301 and the second electrode 302 are elongated and parallel to each other. The first conductive module 303 is disposed between the first electrode 301 and the second electrode 302 and extends from the first electrode 301 to the second electrode 302. A conductive module 303 is specifically in a curve shape, which can also be understood as a wavy shape. In this specific 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 formed by the overall extension direction B of the wavy first conductive module 303 and the extension directions of the first electrode 301 and the second electrode 302 can also be between 0° and 90° or 90°. ~180°, excluding 0° and 180°. Specifically, the angle can be set according to the needs of the temperature field of the corresponding area on the heating component 1, so that the corresponding area of the heating component 1 can preset the required temperature field, and the best atomization effect can be achieved when heating the aerosol to generate the product.
其中,由于在第一电极301与第二电极302之间的直线距离相等,且第一导电模块303的横截面积及电阻率相同的情况下,波浪型的第一导电模块303的曲线总长度大于图3所对应的直线型的第一导电模块303的直线总长度,根据公式:R(电阻)=ρ(电阻率)L(导线长度)/S(导线横截面积);可知,相比于图3中的直线型的第一导电模块303,图4对应的第一导电模块303的电阻较大,图4对应实施例中的高阻导电模块区的总电阻比图3对应实施例中的高阻导电模块区的总电阻要大,则图4对应实施例中的高阻导电模块区的加热速率比图3对应实施例中的高阻导电模块区的功率密度要小,能够根据实际需求进一步对加热组件1的温度场进行微调。Among them, since the linear distance between the first electrode 301 and the second electrode 302 is equal, and the cross-sectional area and resistivity of the first conductive module 303 are the same, the total length of the curve of the wavy first conductive module 303 is greater than the total linear length of the linear first conductive module 303 corresponding to Figure 3, according to the formula: R (resistance) = ρ (resistivity) L (conductor length) / S (conductor cross-sectional area); it can be seen that compared to In the linear first conductive module 303 in Figure 3, the resistance of the first conductive module 303 corresponding to Figure 4 is larger. The total resistance of the high-resistance conductive module area in the corresponding embodiment of Figure 4 is greater than that in the corresponding embodiment of Figure 3. The total resistance of the high-resistance conductive module area is larger, then the heating rate of the high-resistance conductive module area in the corresponding embodiment of Figure 4 is smaller than the power density of the high-resistance conductive module area in the corresponding embodiment of Figure 3. According to actual It is necessary to further fine-tune the temperature field of the heating component 1.
具体的,第一导电模块303的横截面积小于第一电极301的横截面积;或第一导电模块303的横截面积小于第二电极302的横截面积;或者第一导电模块303的横截面积小于第一电极301的横截面积且小于第二电极302的横截面积。这样能够使得第一导电模块303的电阻相对第一电极301和/或第二电极302的电阻较大,在第一电极301与第二电极302分别与电源的正极和负极电连接时,不至于被第一导电模块303短路。可以理解,在具体实施例中,可根据加热组件1需要快速升温的区域以及该区域的温度场的需要对第一导电模块303的位置和其横截面积进行具体设置。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 conductive module 303. The cross-sectional area is smaller than the cross-sectional area of the first electrode 301 and smaller than the cross-sectional area of the second electrode 302 . This can make the resistance of the first conductive module 303 larger than the resistance of the first electrode 301 and/or the second electrode 302, so that when the first electrode 301 and the second electrode 302 are electrically connected to the positive and negative electrodes of the power supply respectively, the resistance will not be short-circuited by the first conductive module 303. It can be understood that in specific embodiments, the position and cross-sectional area of the first conductive module 303 can be specifically set according to the area of the heating component 1 that needs to be heated quickly and the needs of the temperature field in this area.
在具体实施例中,第一电极301、第二电极302以及第一导电模块303的厚度一般较小且三者的厚度基本相同,因此,横截面积越大,则宽度越大;因此,第一导电模块303的横截面积小于第一电极301的横截面积,或第一导电模块303的横截面积小于第二电极302的横截面积,或者第一导电模块303的横截面积小于第一电极301的横截面积且小于第二电极302的横截面积;可以理解为第一导电模块303 的宽度小于第一电极301的宽度,或第一导电模块303的宽度小于第二电极302的宽度,或者第一导电模块303的宽度小于第一电极301的宽度且小于第二电极302的宽度。需要说明的是,这里所说的宽度为第一电极301、第二电极302或第一导电模块303沿垂直于其延伸方向上的尺寸。In a specific embodiment, the thicknesses of the first electrode 301, the second electrode 302 and the first conductive module 303 are generally small and the thicknesses of the three are basically the same. Therefore, the larger the cross-sectional area, the larger the width; therefore, the third The cross-sectional area of a 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 conductive module 303. The cross-sectional area of one electrode 301 is smaller than the cross-sectional area of the second electrode 302; it can be 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. The width, 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 should be noted that the width mentioned here is the size of the first electrode 301, the second electrode 302 or the first conductive module 303 along the direction perpendicular to its extension.
进一步地,在其他实施例中,第一导电模块303的数量可以是多个,多个第一导电模块303间隔设置,每个第一导电模块303分别与第一电极301和第二电极302电连接,即每个第一导电模块303从第一电极301延伸至第二电极302;且多个第一导电模块303中至少两个第一导电模块303的横截面积不同。容易理解,第一导电模块303的横截面积不同,则其阻值不同,其在加热组件1的相应区域的总电阻也不相同,从而不同横截面积的第一导电模块303在加热组件1的相应区域的功率密度也不相同,则相应区域的升温速率不同,即对应形成多个不同的温度场;从而可以将横截面积大的第一导电模块303设置于需要快速升温区域的对应位置,将横截面积略小的设置于相邻区域对应的位置,使得加热组件1的相邻区域可以实现温度梯度下降或上升,以丰富温度场的温度分布方式,适应更多种类的气溶胶生成制品的加热需求。Further, in other embodiments, the number of the first conductive modules 303 may be multiple, and the plurality of first conductive modules 303 are arranged at intervals, and each first conductive module 303 is electrically connected to the first electrode 301 and the second electrode 302 respectively. Connection, that is, each first conductive module 303 extends from the first electrode 301 to the second electrode 302; and at least two of the plurality of first conductive modules 303 have different cross-sectional areas. It is easy to understand that if the cross-sectional area of the first conductive module 303 is different, its resistance value will be different, and its total resistance in the corresponding area of the heating component 1 will also be different. Therefore, the first conductive module 303 with different cross-sectional area will have different resistance in the heating component 1 The power density of the corresponding areas is also different, so the heating rates of the corresponding areas are different, that is, multiple different temperature fields are formed correspondingly; thus, the first conductive module 303 with a large cross-sectional area can be placed at the corresponding position of the area that requires rapid heating. , setting a slightly smaller cross-sectional area at the corresponding position of the adjacent area, so that the adjacent area of the heating component 1 can achieve a temperature gradient decrease or increase, enriching the temperature distribution of the temperature field, and adapting to the generation of more types of aerosols The heating requirements of the product.
在一具体实施中,请参见图5,图5为本申请第三实施例提供的第一导电模块与第一电极和第二电极以及红外发热层展开后的结构示意图。第一导电模块303的数量为两个,两个第一导电模块303均呈直线型,且相互平行,两个第一导电模块303的延伸方向与第一电极301和第二电极302的延伸方向垂直,两个第一导电模块303的横截面积相同,即在本实施例中,两个第一导电模块303的电阻相同,在加热组件1上相应的区域的面积相同,因此相应区域的加热速率也相同,以实现加热组件1上更多的区域均可共同快速升温,对气溶胶生成制品进行快速加热雾化,出雾速度更快。In a specific implementation, please refer to FIG. 5 , which is a schematic structural diagram of the first conductive module, the first electrode, the second electrode, and the infrared heating layer provided in the third embodiment of the present application after unfolding. The number of the first conductive modules 303 is two. The two first conductive modules 303 are linear and parallel to each other.
