Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

下面结合附图和实施例对本申请进行详细的说明。The present application is described in detail below with reference to the accompanying drawings and embodiments.

申请人研究发现，由于现有固态气溶胶生成介质的热导率低，使得在对固态气溶胶生成介质进行烘烤加热时，靠近热源的部位容易焦糊，导致生成的气溶胶口感较差，远离热源位置的气溶胶生成介质由于导热不足使得气溶胶释放量不足，导致用户满足感低。且要实现快速释放气溶胶需要有精确的温控技术，目前的加热方式难以准确的进行温度调节。The applicant has found that due to the low thermal conductivity of the existing solid aerosol generating medium, when the solid aerosol generating medium is baked and heated, the part close to the heat source is easy to burn, resulting in a poor taste of the generated aerosol, and the aerosol generating medium far from the heat source has insufficient thermal conductivity, resulting in insufficient aerosol release, resulting in low user satisfaction. In addition, precise temperature control technology is required to achieve rapid release of aerosol, and it is difficult to accurately adjust the temperature using the current heating method.

具体的，本申请提供一种气溶胶生成制品100，包括基底10和气溶胶生成介质20。其中，气溶胶生成介质20设置于基底10的一侧，且包括第一气溶胶生成介质30和第二气溶胶生成介质40。Specifically, the present application provides an aerosol generating article 100 , including a substrate 10 and an aerosol generating medium 20 . The aerosol generating medium 20 is disposed on one side of the substrate 10 , and includes a first aerosol generating medium 30 and a second aerosol generating medium 40 .

其中，气溶胶生成制品100的形状不限于如图1、图12、图14以及图17所示的方片状、圆柱状等，还可以为圆饼状、棱柱状等，且沿垂直于A-A线的横截面可以呈三角形、五角星、椭圆形、矩形、菱形等任意形状；气溶胶生成制品100的长度和/或宽度可以伸长或者缩小。在此不作限定例。The shape of the aerosol generating article 100 is not limited to the square sheet, cylindrical shape, etc. shown in FIG. 1, FIG. 12, FIG. 14, and FIG. 17, and may also be a round cake, a prism, etc., and the cross section perpendicular to the A-A line may be a triangle, a five-pointed star, an ellipse, a rectangle, a diamond, etc.; the length and/or width of the aerosol generating article 100 may be extended or reduced. No limiting examples are given here.

其中，第一气溶胶生成介质30可以为丝状、片状、薄片状、颗粒状、粉末状、柱状体等含特定香气的植物茎叶类固态介质；也可以是其他类型的有序固态气溶胶生成介质、无序固态气溶胶生成介质以及颗粒固态气溶胶生成介质等。其中，第一气溶胶生成介质30可在温度高于250℃时可以产生气溶胶。The first aerosol generating medium 30 may be a solid medium of plant stems and leaves containing a specific aroma, such as filaments, sheets, flakes, particles, powders, columns, etc.; or other types of ordered solid aerosol generating medium, disordered solid aerosol generating medium, and particle solid aerosol generating medium, etc. The first aerosol generating medium 30 may generate aerosol when the temperature is higher than 250°C.

第二气溶胶生成介质40可以为含有特定香气的甘油、丙二醇等油状物添加增稠剂，使得在常温下处于凝胶态的固态物质。可以理解的，在一个例子中，凝胶态的第二气溶胶生成介质40的导热能力高于第一气溶胶生成介质30的导热能力。当然，第二气溶胶生成介质40也可以是其他具有高热导率的固态物质，在此不做限定。The second aerosol generating medium 40 can be a solid substance in a gel state at room temperature by adding a thickener to an oily substance such as glycerin or propylene glycol containing a specific aroma. It can be understood that, in one example, the thermal conductivity of the second aerosol generating medium 40 in a gel state is higher than the thermal conductivity of the first aerosol generating medium 30. Of course, the second aerosol generating medium 40 can also be other solid substances with high thermal conductivity, which is not limited here.

其中，在第一温度下，第一气溶胶生成介质30与第二气溶胶生成介质40均处于第一状态，其中，第一温度可以为室温或者温度小于第一预设温度的温度，其中，第一预设温度可以小于为100°，且第一预设温度下的第一气溶胶生成介质30与第二气溶胶生成介质40的状态不会发生变化；第一状态为固态。Among them, at the first temperature, the first aerosol generating medium 30 and the second aerosol generating medium 40 are both in the first state, wherein the first temperature can be room temperature or a temperature lower than the first preset temperature, wherein the first preset temperature can be lower than 100°, and the states of the first aerosol generating medium 30 and the second aerosol generating medium 40 at the first preset temperature will not change; the first state is solid.

在第二温度下，第一气溶胶生成介质30维持在第一状态，第二气 溶胶生成介质40转变为第二状态；其中，第二温度可以大于100°，第二状态可以为气态或者液态，第二气溶胶生成介质40转变为第二状态可以是熔化、升华等吸热过程，可以理解的，第二气溶胶生成介质40由固态转化为气态或者液态，需要吸收能量，因此，第二温度大于第一温度，第二气溶胶生成介质40由第一状态转变为第二状态为吸热的过程。At the second temperature, the first aerosol generating medium 30 is maintained in the first state, and the second aerosol generating medium 30 is maintained in the first state. The sol generating medium 40 is transformed into a second state; wherein, the second temperature may be greater than 100°, the second state may be a gaseous state or a liquid state, and the transformation of the second aerosol generating medium 40 into the second state may be an endothermic process such as melting or sublimation. It can be understood that the second aerosol generating medium 40 needs to absorb energy when it is transformed from a solid state to a gaseous state or a liquid state. Therefore, the second temperature is greater than the first temperature, and the transformation of the second aerosol generating medium 40 from the first state to the second state is an endothermic process.

具体的，本申请实施例提供的气溶胶生成制品100，通过设置气溶胶生成介质20包括第一气溶胶生成介质30和第二气溶胶生成介质40，且第二气溶胶生成介质40在第二温度下吸热由第一状态转变为第二状态，一方面可以将第一气溶胶生成介质30上多余的能量吸收消耗，避免第一气溶胶生成介质30局部焦糊；另一方面第二气溶胶生成介质40的热导率较高，可以起到传递热量的作用，从而维持第一气溶胶生成介质30的温度稳定，保持气溶胶生成介质20的整体温度均匀，无须实时温度反馈，从而能够降低温控技术难度，实现对气溶胶生成介质20的均匀加热。Specifically, the aerosol generating product 100 provided in the embodiment of the present application, by setting the aerosol generating medium 20 to include a first aerosol generating medium 30 and a second aerosol generating medium 40, and the second aerosol generating medium 40 absorbs heat at the second temperature and changes from the first state to the second state. On the one hand, it can absorb and consume excess energy on the first aerosol generating medium 30 to avoid local burning of the first aerosol generating medium 30; on the other hand, the second aerosol generating medium 40 has a high thermal conductivity and can play a role in transferring heat, thereby maintaining the temperature of the first aerosol generating medium 30 stable and keeping the overall temperature of the aerosol generating medium 20 uniform, without the need for real-time temperature feedback, thereby reducing the difficulty of temperature control technology and achieving uniform heating of the aerosol generating medium 20.

在一实施例中，在第三温度下，第一气溶胶生成介质30维持在第一状态，第二气溶胶生成介质40由第二状态转变为第三状态；第二气溶胶生成介质由第二状态转变为第三状态为吸热的过程。其中，本实施例中，第二状态可以为液态，第三状态可以为气态，第二气溶胶生成介质40由固态转变为液态，以及从液态转变为气态时，同时吸收大量的热量并释放出气溶胶，使得快速加热时第一气溶胶生成介质30的温度容易适中保持在一个稳定状态，使得第一气溶胶生成介质30不会焦糊，对抽吸体验有明显的帮助；且第二气溶胶生成介质40可以让温度相对稳定，无需实时的温度反馈，降低温控检测成本。In one embodiment, at the third temperature, the first aerosol generating medium 30 is maintained in the first state, and the second aerosol generating medium 40 is changed from the second state to the third state; the second aerosol generating medium is changed from the second state to the third state in a heat absorption process. In this embodiment, the second state can be a liquid state, and the third state can be a gaseous state. When the second aerosol generating medium 40 is changed from a solid state to a liquid state, and from a liquid state to a gaseous state, it absorbs a large amount of heat and releases aerosol at the same time, so that the temperature of the first aerosol generating medium 30 is easy to be moderately maintained in a stable state when heated rapidly, so that the first aerosol generating medium 30 will not be burnt, which is significantly helpful for the smoking experience; and the second aerosol generating medium 40 can make the temperature relatively stable, without the need for real-time temperature feedback, and reduce the cost of temperature control detection.

其中，第一温度可以为一个温度值或者一个温度范围，第二温度可以为一个温度值或者一个温度范围，第三温度可以为一个温度值或者一个温度范围。The first temperature may be a temperature value or a temperature range, the second temperature may be a temperature value or a temperature range, and the third temperature may be a temperature value or a temperature range.

本实施例中，第二气溶胶生成介质40为含有特定香气的甘油、丙二醇等的凝胶态物质，第二气溶胶生成介质40可在温度高于100摄氏 度时主成分会液化；高于250℃时液化的凝胶介质发生气化，同时吸收大量的热量并释放出气溶胶。需要说明的是，由于材料特性，第二气溶胶生成介质40加热生成的气溶胶量大于第一气溶胶生成介质30加热生成的气溶胶量，以提高用户满足感。In this embodiment, the second aerosol generating medium 40 is a gel-like substance such as glycerin or propylene glycol containing a specific aroma. The second aerosol generating medium 40 can be heated to a temperature higher than 100 degrees Celsius. When the temperature is higher than 250°C, the main component will liquefy; when the temperature is higher than 250°C, the liquefied gel medium will gasify, absorbing a large amount of heat and releasing aerosol. It should be noted that due to the material characteristics, the amount of aerosol generated by heating the second aerosol generating medium 40 is greater than the amount of aerosol generated by heating the first aerosol generating medium 30, so as to improve user satisfaction.

其中，对气溶胶生成制品100加热的方式可以为周圈式感应加热、中心针式电阻加热、激光加热中的至少一种。The aerosol generating product 100 may be heated by at least one of circumferential induction heating, central needle resistance heating, and laser heating.

请继续参见图3，在本申请实施例中，对气溶胶生成制品100加热的方式为激光加热，且基底10包括光热转换材料层11和导热层12，光热转换材料层11用于吸收激光能量并产生热能；导热层12设置于光热转换材料与气溶胶生成介质20之间，用于将光热转换材料层11产生的热能传递给气溶胶生成介质20，以加热气溶胶生成介质20生成可供用户使用的气溶胶。Please continue to refer to Figure 3. In the embodiment of the present application, the aerosol generating product 100 is heated by laser heating, and the substrate 10 includes a photothermal conversion material layer 11 and a heat conductive layer 12. The photothermal conversion material layer 11 is used to absorb laser energy and generate heat energy; the heat conductive layer 12 is arranged between the photothermal conversion material and the aerosol generating medium 20, and is used to transfer the heat energy generated by the photothermal conversion material layer 11 to the aerosol generating medium 20, so as to heat the aerosol generating medium 20 to generate an aerosol that can be used by the user.

其中，导热层12包括但不限于铝箔、铜箔、不锈钢等具有高热导率的材料。The heat-conducting layer 12 includes but is not limited to materials with high thermal conductivity such as aluminum foil, copper foil, and stainless steel.

其中，光热转换材料层11包括但不限于高吸收率的陶瓷涂层、含碳涂料，或其他可以吸收激光的材料。The photothermal conversion material layer 11 includes but is not limited to a ceramic coating with a high absorption rate, a carbon-containing coating, or other materials that can absorb laser light.

当然，在另一实施例中，也可不设置导热层12，光热转换材料层11直接设置于气溶胶生成介质20一侧，或包裹气溶胶生成介质20。Of course, in another embodiment, the heat-conducting layer 12 may not be provided, and the light-to-heat conversion material layer 11 may be directly provided on one side of the aerosol generating medium 20 , or may wrap the aerosol generating medium 20 .

以下以热源为半导体激光芯片通过给半导体激光芯片提供电流输出激光，激光波段在355到1550nm之间；以第二气溶胶生成介质40为含有特定香气的甘油、丙二醇等的凝胶态物质，厚度为0.01mm-0.5mm；以第一气溶胶生成介质30的厚度为0.05mm-0.4mm的条件下进行描述。The following description is made under the condition that the heat source is a semiconductor laser chip which outputs laser by providing current to the semiconductor laser chip, and the laser wavelength ranges from 355 to 1550 nm; the second aerosol generating medium 40 is a gel-state substance containing glycerin, propylene glycol, etc. with a specific aroma, and the thickness is 0.01 mm-0.5 mm; and the thickness of the first aerosol generating medium 30 is 0.05 mm-0.4 mm.

具体的，设置第二气溶胶生成介质40的厚度为0.01mm-0.5mm的目的是第二气溶胶生成介质40加热后会释放气溶胶，物理状态表现为凝胶态到液态到气态，逐层气化，厚度太薄不足以激发足够的气溶胶，厚度太厚单次加热不足以充分释放所有凝胶，造成浪费。设置第一气溶胶生成介质30的厚度为0.05mm-0.4mm的目的在于第一气溶胶生成介质30太厚会导致气溶胶释放不畅，降低气溶胶释放量，第一气溶胶生成介质30太薄会导致自身的气溶胶生成物过少，降低气溶胶释放量。 Specifically, the purpose of setting the thickness of the second aerosol generating medium 40 to 0.01mm-0.5mm is that the second aerosol generating medium 40 will release aerosol after heating, and the physical state is manifested as gel state to liquid state to gas state, and vaporization layer by layer. If the thickness is too thin, it is not enough to stimulate enough aerosol, and if the thickness is too thick, a single heating is not enough to fully release all the gels, resulting in waste. The purpose of setting the thickness of the first aerosol generating medium 30 to 0.05mm-0.4mm is that if the first aerosol generating medium 30 is too thick, the aerosol release will be poor, reducing the amount of aerosol released, and if the first aerosol generating medium 30 is too thin, it will result in too little aerosol generated by itself, reducing the amount of aerosol released.

当然，还可以根据实际情况，设置其他合适厚度范围的第一气溶胶生成介质30和第二气溶胶生成介质40，在此不做限定。Of course, the first aerosol generating medium 30 and the second aerosol generating medium 40 may be provided with other suitable thickness ranges according to actual conditions, which are not limited here.

参见图1-图11，在本申请的第一实施例中，第一气溶胶生成介质30形成第一气溶胶生成介质层，第二气溶胶生成介质40形成第二气溶胶生成介质层，且第一气溶胶生成介质层和第二气溶胶生成介质层层叠设置。1-11 , in the first embodiment of the present application, the first aerosol generating medium 30 forms a first aerosol generating medium layer, the second aerosol generating medium 40 forms a second aerosol generating medium layer, and the first aerosol generating medium layer and the second aerosol generating medium layer are stacked.

参见图2或图3，具体的，第二气溶胶生成介质层设置于第一气溶胶生成介质层与基底10之间，热源加热光热转换材料层11，光热转换材料层11吸收激光能量后通过导热层12加热第二气溶胶生成介质层，第二气溶胶生成介质层吸收热量后一部分热量会被释放的气溶胶带走，一部分热量会传递给第一气溶胶生成介质层，实现第一气溶胶生成介质层与第二气溶胶生成介质层同时释放气溶胶，由于第二气溶胶生成介质层吸热融化会吸收大量热量，使得第一气溶胶生成介质层的温度容易适中保持在一个稳定状态。另外，由于第一气溶胶生成介质30需要预热一定时间才能生成气溶胶，而第二气溶胶生成介质40在温度达到条件时即可快速出雾，因此，本实施例中第二气溶胶生成介质层先吸收热量，可以实现快速释放气溶胶。Referring to FIG. 2 or FIG. 3, specifically, the second aerosol generating medium layer is disposed between the first aerosol generating medium layer and the substrate 10, the heat source heats the photothermal conversion material layer 11, and the photothermal conversion material layer 11 absorbs the laser energy and heats the second aerosol generating medium layer through the heat conducting layer 12. After the second aerosol generating medium layer absorbs the heat, part of the heat will be taken away by the released aerosol, and part of the heat will be transferred to the first aerosol generating medium layer, so that the first aerosol generating medium layer and the second aerosol generating medium layer release aerosols at the same time. Since the second aerosol generating medium layer absorbs heat and melts, it will absorb a large amount of heat, so that the temperature of the first aerosol generating medium layer is easy to be moderate and maintained in a stable state. In addition, since the first aerosol generating medium 30 needs to be preheated for a certain period of time to generate aerosols, and the second aerosol generating medium 40 can quickly emit mist when the temperature reaches the condition, therefore, in this embodiment, the second aerosol generating medium layer absorbs heat first, so that the aerosol can be quickly released.

参见图4，具体的，第一气溶胶生成介质层设置于第二气溶胶生成介质层与基底10之间，热源加热光热转换材料层11，光热转换材料层11吸收激光能量后通过导热层12加热第一气溶胶生成介质层，第一气溶胶生成介质层吸收热量后一部分热量会被释放的气溶胶带走，一部分热量会传递给第二气溶胶生成介质层，第二气溶胶生成介质层吸收热量融化并释放大量气溶胶，实现第一气溶胶生成介质层与第二气溶胶生成介质层同时释放气溶胶，由于第二气溶胶生成介质层加热过程中会吸收大量热量，使得第一气溶胶生成介质30的温度容易适中保持在一个稳定状态。Referring to FIG4 , specifically, the first aerosol generating medium layer is disposed between the second aerosol generating medium layer and the substrate 10, and the heat source heats the photothermal conversion material layer 11. After the photothermal conversion material layer 11 absorbs laser energy, it heats the first aerosol generating medium layer through the heat conductive layer 12. After the first aerosol generating medium layer absorbs heat, part of the heat will be taken away by the released aerosol, and part of the heat will be transferred to the second aerosol generating medium layer. The second aerosol generating medium layer absorbs heat, melts and releases a large amount of aerosol, so that the first aerosol generating medium layer and the second aerosol generating medium layer release aerosols at the same time. Since the second aerosol generating medium layer absorbs a large amount of heat during the heating process, the temperature of the first aerosol generating medium 30 is easy to be moderately maintained in a stable state.

进一步，本申请第一实施例中，第一气溶胶生成介质层和第二气溶胶生成介质层中的一个可以为图案化的气溶胶生成介质层，图案化的气溶胶生成介质层具有若干开口X。 Further, in the first embodiment of the present application, one of the first aerosol generating medium layer and the second aerosol generating medium layer may be a patterned aerosol generating medium layer, and the patterned aerosol generating medium layer has a plurality of openings X.

具体的，第一气溶胶生成介质30加热生成的第一气溶胶具有较强烈的本香，第二气溶胶生成介质40加热生成的第二气溶胶具有较大的雾化量，因此，通过调节生成的混合气溶胶中的第一气溶胶和第二气溶胶的占比，可以满足不同用户的口感需求。Specifically, the first aerosol generated by heating the first aerosol generating medium 30 has a stronger original fragrance, and the second aerosol generated by heating the second aerosol generating medium 40 has a larger atomization amount. Therefore, by adjusting the proportion of the first aerosol and the second aerosol in the generated mixed aerosol, the taste requirements of different users can be met.

参见图5，第二气溶胶生成介质层设置于第一气溶胶生成介质层与基底10之间，且第二气溶胶生成介质层为图案化的气溶胶生成介质层。具体的，通过在第二气溶胶生成介质层上设置开口X，即可以减少第二气溶胶生成介质层的物质含量，从而减少第二气溶胶生成介质层生成的第二气溶胶量，进而提高第一气溶胶生成介质层生成的第一气溶胶量的占比，从而提高混合气溶胶的本香。5 , the second aerosol generating medium layer is disposed between the first aerosol generating medium layer and the substrate 10, and the second aerosol generating medium layer is a patterned aerosol generating medium layer. Specifically, by providing an opening X on the second aerosol generating medium layer, the substance content of the second aerosol generating medium layer can be reduced, thereby reducing the amount of the second aerosol generated by the second aerosol generating medium layer, thereby increasing the proportion of the first aerosol generated by the first aerosol generating medium layer, and thus improving the original fragrance of the mixed aerosol.

参见图6，第二气溶胶生成介质层设置于第一气溶胶生成介质层与基底10之间，且第一气溶胶生成介质层为图案化的气溶胶生成介质层。具体的，通过在第一气溶胶生成介质层上设置开口X，即可以减少第一气溶胶生成介质层的物质含量，从而减少第一气溶胶生成介质层生成的第一气溶胶量，进而提高第二气溶胶生成介质层生成的第二气溶胶量的占比，减少混合气溶胶的本香，以满足不同用户的口味需求。6 , the second aerosol generating medium layer is disposed between the first aerosol generating medium layer and the substrate 10, and the first aerosol generating medium layer is a patterned aerosol generating medium layer. Specifically, by providing an opening X on the first aerosol generating medium layer, the substance content of the first aerosol generating medium layer can be reduced, thereby reducing the amount of the first aerosol generated by the first aerosol generating medium layer, thereby increasing the proportion of the second aerosol generated by the second aerosol generating medium layer, and reducing the original aroma of the mixed aerosol, so as to meet the taste requirements of different users.

参见图7，第一气溶胶生成介质层设置于第二气溶胶生成介质层与基底10之间，且第一气溶胶生成介质层为图案化的气溶胶生成介质层。具体的，通过在第一气溶胶生成介质层上设置开口X，即可以减少第一气溶胶生成介质层的物质含量，从而减少第一气溶胶生成介质层生成的第一气溶胶量，进而提高第二气溶胶生成介质层生成的第二气溶胶量的占比，减少混合气溶胶的本香，以满足不同用户的口味需求。7 , the first aerosol generating medium layer is disposed between the second aerosol generating medium layer and the substrate 10, and the first aerosol generating medium layer is a patterned aerosol generating medium layer. Specifically, by providing an opening X on the first aerosol generating medium layer, the substance content of the first aerosol generating medium layer can be reduced, thereby reducing the amount of the first aerosol generated by the first aerosol generating medium layer, thereby increasing the proportion of the second aerosol generated by the second aerosol generating medium layer, and reducing the original aroma of the mixed aerosol, so as to meet the taste requirements of different users.

其中，以气溶胶生成介质呈方片状为例，参见图8，上述图案化的气溶胶生成介质层可以为一整体结构，若干开口X可以为设置在图案化的气溶胶生成介质层上的通孔。Taking the aerosol generating medium in the shape of a square sheet as an example, referring to FIG. 8 , the patterned aerosol generating medium layer may be an integral structure, and the plurality of openings X may be through holes disposed on the patterned aerosol generating medium layer.

或者，上述图案化的气溶胶生成介质层可以为分体结构。例如，如图9所示，第二气溶胶生成介质层为图案化的气溶胶生成介质层，若干开口X将第二气溶胶生成介质层分为多个独立的第二气溶胶生成介质块41，且相邻两个第二气溶胶生成介质块41之间的距离为0.1-5mm， 例如，可以为0.1mm、0.5mm、2mm、3mm、4mm或5mm等。Alternatively, the patterned aerosol generating medium layer may be a split structure. For example, as shown in FIG9 , the second aerosol generating medium layer is a patterned aerosol generating medium layer, and a plurality of openings X divide the second aerosol generating medium layer into a plurality of independent second aerosol generating medium blocks 41, and the distance between two adjacent second aerosol generating medium blocks 41 is 0.1-5 mm. For example, it may be 0.1 mm, 0.5 mm, 2 mm, 3 mm, 4 mm or 5 mm.

具体的，若相邻两个第二气溶胶生成介质块41过大，则可能导致投影位于相邻两个第二气溶胶生成介质块41之间的第一气溶胶生成介质层的部分热量传递不充分，从而导致其难以达到雾化温度而释放的第一气溶胶不足。本实施例通过设置相邻两个第二气溶胶生成介质块41之间的距离为0.1-5mm，可以保证第二气溶胶生成介质块41对其上的第一气溶胶生成介质层的热传递效果，避免第一气溶胶生成介质层受热不足导致雾化量低。Specifically, if the distance between two adjacent second aerosol generating medium blocks 41 is too large, the heat transfer of the first aerosol generating medium layer projected between the two adjacent second aerosol generating medium blocks 41 may be insufficient, thereby making it difficult for the first aerosol generating medium layer to reach the atomization temperature and releasing insufficient first aerosol. In this embodiment, by setting the distance between the two adjacent second aerosol generating medium blocks 41 to be 0.1-5 mm, the heat transfer effect of the second aerosol generating medium block 41 on the first aerosol generating medium layer can be ensured, thereby avoiding insufficient heating of the first aerosol generating medium layer and resulting in low atomization amount.

进一步，本申请第一实施例中，图案化的气溶胶生成介质层可以靠近基底10设置，且基底10具有凸起部13，凸起部13延伸至开口(图未标)内，且与第一气溶胶生成介质层与第二气溶胶生成介质层中的另一个接触。其中，如图10和图11所示，图案化的气溶胶生成介质层为图案化的第二气溶胶生成介质层，凸起部13延伸至开口内，且与第一气溶胶生成介质层接触。Further, in the first embodiment of the present application, the patterned aerosol generating medium layer can be arranged close to the substrate 10, and the substrate 10 has a protrusion 13, the protrusion 13 extends into the opening (not shown) and contacts the other of the first aerosol generating medium layer and the second aerosol generating medium layer. As shown in FIG. 10 and FIG. 11, the patterned aerosol generating medium layer is a patterned second aerosol generating medium layer, and the protrusion 13 extends into the opening and contacts the first aerosol generating medium layer.

具体的，通过设置基底10具有凸起部13，凸起部13延伸至开口内与非图案化的气溶胶生成介质层接触，可以实现对层叠设置的两个气溶胶生成基质层同时传递热量，提高雾化效率。且本实施例中，可以不限定相邻两个介质块之间的距离。Specifically, by providing the base 10 with a protrusion 13, the protrusion 13 extends into the opening to contact the non-patterned aerosol generating medium layer, so that heat can be transferred to the two stacked aerosol generating matrix layers at the same time, thereby improving the atomization efficiency. In this embodiment, the distance between two adjacent medium blocks may not be limited.

参见图13-图16，在本申请的第二实施例中，第一气溶胶生成介质30与第二气溶胶生成介质40均呈图案化且同层设置；且图案化的第一气溶胶生成介质30与图案化的第二气溶胶生成介质40形成互补图案。13-16 , in the second embodiment of the present application, the first aerosol generating medium 30 and the second aerosol generating medium 40 are both patterned and arranged in the same layer; and the patterned first aerosol generating medium 30 and the patterned second aerosol generating medium 40 form complementary patterns.

例如，参见图12和图13，图案化的第一气溶胶生成介质30包括若干第一气溶胶生成介质块31，图案化的第二气溶胶生成介质40包括若干第二气溶胶生成介质块41，若干第一气溶胶生成介质块31和若干第二气溶胶生成介质块41交替排布，从而形成互补图案。其中，相邻两个第二气溶胶生成介质块41之间的距离为0.1-5mm。例如，可以为0.1mm、0.5mm、2mm、3mm、4mm或5mm等。For example, referring to FIG. 12 and FIG. 13 , the patterned first aerosol generating medium 30 includes a plurality of first aerosol generating medium blocks 31, and the patterned second aerosol generating medium 40 includes a plurality of second aerosol generating medium blocks 41. The plurality of first aerosol generating medium blocks 31 and the plurality of second aerosol generating medium blocks 41 are arranged alternately to form a complementary pattern. The distance between two adjacent second aerosol generating medium blocks 41 is 0.1-5 mm. For example, it can be 0.1 mm, 0.5 mm, 2 mm, 3 mm, 4 mm or 5 mm, etc.

具体的，虽然基底10上的热量可以直接传递给第一气溶胶生成介质块31，但是现有加热方式难以实现准确控温，若相邻两个第二气溶胶 生成介质块41过大，则第二气溶胶生成介质块41传递的能量以及融化吸收的热量可能无法维持第一气溶胶生成介质块31的温度处于相对稳定的状态，因此，设置相邻两个第二气溶胶生成介质块41之间的距离为0.1-5mm，可以利用第二气溶胶生成介质块41融化吸收大量的热量使得第一气溶胶生成介质30的温度保持在一个稳定状态，使得第一气溶胶生成介质30不会焦糊，对抽吸体验有明显的帮助；且第二气溶胶生成介质40可以让温度相对稳定，无需实时的温度反馈，降低温控检测成本。Specifically, although the heat on the substrate 10 can be directly transferred to the first aerosol generating medium block 31, it is difficult to achieve accurate temperature control in the existing heating method. If the generating medium block 41 is too large, the energy transmitted by the second aerosol generating medium block 41 and the heat absorbed by melting may not be able to maintain the temperature of the first aerosol generating medium block 31 in a relatively stable state. Therefore, the distance between two adjacent second aerosol generating medium blocks 41 is set to 0.1-5mm. The second aerosol generating medium block 41 can be used to melt and absorb a large amount of heat to keep the temperature of the first aerosol generating medium 30 in a stable state, so that the first aerosol generating medium 30 will not burn, which is significantly helpful for the smoking experience; and the second aerosol generating medium 40 can make the temperature relatively stable, without the need for real-time temperature feedback, thereby reducing the cost of temperature control detection.

再例如，参见图14和图15，图案化的第二气溶胶生成介质40具有间隔设置的若干开口(图未标)，图案化的第一气溶胶生成介质30包括间隔设置且与开口形状及大小相同的若干第一气溶胶生成介质块31，每个第一气溶胶生成介质块31容置于一个开口内，从而形成互补图案。For another example, referring to Figures 14 and 15, the patterned second aerosol generating medium 40 has a plurality of openings (not marked in the figures) that are spaced apart, and the patterned first aerosol generating medium 30 includes a plurality of first aerosol generating medium blocks 31 that are spaced apart and have the same shape and size as the openings, and each first aerosol generating medium block 31 is accommodated in an opening, thereby forming a complementary pattern.

又例如，参见图16，图案化的第一气溶胶生成介质30具有第一啮合部32，图案化的第二气溶胶生成介质40具有第二啮合部42，第一啮合部32和第二啮合部42互补，从而使得图案化的第一气溶胶生成介质30与图案化的第二气溶胶生成介质40通过第一啮合部32和第二啮合部42连接在一起。其中，第一啮合部32和第二啮合部42中的一个第一齿状，另一个为与该第一齿状互补的第二齿状；或者，第一啮合部32和第二啮合部42中的一个第一弧状，另一个为与该第一弧状互补的第二弧状；再或者，第一啮合部32和第二啮合部42中的一个凹槽，另一个为与该凹槽互补的凸起。具体可根据实际需要设计。For another example, referring to FIG. 16 , the patterned first aerosol generating medium 30 has a first meshing portion 32, and the patterned second aerosol generating medium 40 has a second meshing portion 42, and the first meshing portion 32 and the second meshing portion 42 are complementary, so that the patterned first aerosol generating medium 30 and the patterned second aerosol generating medium 40 are connected together through the first meshing portion 32 and the second meshing portion 42. Among them, one of the first meshing portion 32 and the second meshing portion 42 is a first tooth shape, and the other is a second tooth shape complementary to the first tooth shape; or one of the first meshing portion 32 and the second meshing portion 42 is a first arc shape, and the other is a second arc shape complementary to the first arc shape; or one of the first meshing portion 32 and the second meshing portion 42 is a groove, and the other is a protrusion complementary to the groove. The specific design can be based on actual needs.

具体的，区别于现有技术，本申请提供的气溶胶生成基质，通过设置气溶胶生成介质20包括第一气溶胶生成介质30和第二气溶胶生成介质40，且第二气溶胶生成介质40在第二温度下吸热由第一状态转变为第二状态，一方面可以将第一气溶胶生成介质30上多余的能量吸收消耗，避免第一气溶胶生成介质30局部焦糊；另一方面第二气溶胶生成介质40的热导率较高，可以起到传递热量的作用，从而维持第一气溶胶生成介质30的温度稳定，保持气溶胶生成介质20的整体温度均匀，无须实时温度反馈，从而能够降低温控技术难度，实现对气溶胶生成介 质20的均匀加热。Specifically, different from the prior art, the aerosol generating matrix provided by the present application is provided with an aerosol generating medium 20 including a first aerosol generating medium 30 and a second aerosol generating medium 40, and the second aerosol generating medium 40 absorbs heat at the second temperature and changes from the first state to the second state. On the one hand, the excess energy of the first aerosol generating medium 30 can be absorbed and consumed to avoid local burning of the first aerosol generating medium 30; on the other hand, the second aerosol generating medium 40 has a high thermal conductivity and can transfer heat, thereby maintaining the temperature of the first aerosol generating medium 30 stable and the overall temperature of the aerosol generating medium 20 uniform, without the need for real-time temperature feedback, thereby reducing the difficulty of temperature control technology and achieving control of the aerosol generating medium. Uniform heating of quality 20.
