具体实施方式Detailed ways
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
图2-4所示为本发明一些实施例中的发热组件10，该发热组件10可应用于雾化器中对烟液、药液等液态介质进行加热雾化，其可包括用于吸取液态介质的多孔体11以及用于对吸附到多孔体11中的液态介质进行加热雾化的发热体12a。该多孔体11包括相对设置的第一面和第二面1121。其中，该第一面为用于安装发热体12a的雾化面1111，第二面1121向内凹陷形成一用于容置导液元件20(参见图15)的导液孔1122。该导液孔1122的形状不限于圆孔，也可以是方孔、长方形孔等其他形状。Figures 2-4 show the heating component 10 in some embodiments of the present invention. The heating component 10 can be used in an atomizer to heat and atomize liquid media such as smoke liquid and medicinal liquid. The porous body 11 of the medium and the heat generating body 12a for heating and atomizing the liquid medium adsorbed in the porous body 11 . The porous body 11 includes a first surface and a second surface 1121 opposite to each other. Wherein, the first surface is the atomizing surface 1111 for installing the heating element 12a, and the second surface 1121 is recessed inward to form a liquid guiding hole 1122 for accommodating the liquid guiding element 20 (see FIG. 15 ). The shape of the liquid guide hole 1122 is not limited to a round hole, and may also be a square hole, a rectangular hole and other shapes.
多孔体11在一些实施例中可包括呈阶梯型的第一基体111和第二基体112，且第一基体111的横截面积大于第二基体112的横截面积，以使第一基体111与第二基体112之间形成有定位的台阶，方便发热组件10的安装定位。优选地，第一基体111远离第二基体112的一侧面形成雾化面1111，从而可使得发热组件10占据空间不变的情况下，增加雾化面1111的面积。In some embodiments, the porous body 11 may include a stepped first matrix 111 and a second matrix 112, and the cross-sectional area of the first matrix 111 is greater than that of the second matrix 112, so that the first matrix 111 and the second matrix 112 Positioning steps are formed between the second bases 112 to facilitate the installation and positioning of the heating element 10 . Preferably, an atomizing surface 1111 is formed on a side of the first base 111 away from the second base 112 , so that the area of the atomizing surface 1111 can be increased without changing the space occupied by the heating component 10 .
第一基体111、第二基体112在本实施例中均大致呈长方体状，雾化面1111形成在第一基体111的长方形表面上。进一步地，第一基体111的长度可大于第二基体112的长度，第一基体111的宽度可与第二基体112的宽度相当。在其他实施例中，第一基体111、第二基体112的截面也可以为圆形、椭圆形、菱形、方形等其他形状。In this embodiment, the first base body 111 and the second base body 112 are substantially rectangular parallelepiped, and the atomizing surface 1111 is formed on the rectangular surface of the first base body 111 . Further, the length of the first base 111 may be greater than the length of the second base 112 , and the width of the first base 111 may be equivalent to the width of the second base 112 . In other embodiments, the cross sections of the first base body 111 and the second base body 112 may also be in other shapes such as circle, ellipse, rhombus, and square.
导液孔1122具有一底面1123，导液孔1122的底面1123在雾化面1111的投影区为核心雾化区域A，该核心雾化区域A为发热体12a的集中分布区。正常工作时，在发热体12a加热预设时间后，核心雾化区域A的第一平均温度高于整个雾化面1111的第二平均温度。The liquid guide hole 1122 has a bottom surface 1123, and the projection area of the bottom surface 1123 of the liquid guide hole 1122 on the atomization surface 1111 is the core atomization area A, and the core atomization area A is the concentrated distribution area of the heating element 12a. During normal operation, after the heating element 12a is heated for a preset time, the first average temperature of the core atomization area A is higher than the second average temperature of the entire atomization surface 1111 .
雾化面1111通常可包括核心雾化区域A以及位于核心雾化区域A外的边缘雾化区域B，核心雾化区域A通常可位于雾化面1111的中心位置。导液元件将雾化器储液腔中的液态介质导到多孔体11，以导液孔1122的底面1123为中心，液体向外扩散，雾化面1111对应底面1123形成一个核心雾化区域A，而液体外扩形成边缘雾化区域B。发热组件10在加热的时候，因为核心雾化区域A的温度较高，液态介质挥发的较快，除了导液元件的液态介质，边缘雾化区域B的部分液态介质也会流向核心雾化区域A，向核心雾化区域A聚集，因此边缘雾化区域B会限定在一定范围内，从而可避免漏液的情况，用户吸雾的时候不会吸入液滴，提升了用户体验。The atomization surface 1111 may generally include a core atomization area A and an edge atomization area B located outside the core atomization area A, and the core atomization area A may generally be located at the center of the atomization surface 1111 . The liquid guide element guides the liquid medium in the liquid storage chamber of the nebulizer to the porous body 11, centering on the bottom surface 1123 of the liquid guide hole 1122, the liquid diffuses outward, and the atomization surface 1111 corresponds to the bottom surface 1123 to form a core atomization area A , and the liquid expands to form the edge atomization area B. When the heating component 10 is heated, because the temperature of the core atomization area A is higher, the liquid medium volatilizes faster. In addition to the liquid medium of the liquid guide element, part of the liquid medium in the edge atomization area B will also flow to the core atomization area A, gather towards the core atomization area A, so the edge atomization area B will be limited to a certain range, so as to avoid liquid leakage, and the user will not inhale liquid droplets when inhaling mist, which improves the user experience.
在一些实施例中，第一平均温度与第二平均温度的温度差可被配置成能够使边缘雾化区域B的部分液态介质流向核心雾化区域A。优选地，第一平均温度可以为120-200℃，第一平均温度可高于第二平均温度20℃以上。In some embodiments, the temperature difference between the first average temperature and the second average temperature can be configured to enable part of the liquid medium in the edge atomization area B to flow to the core atomization area A. Preferably, the first average temperature may be 120-200°C, and the first average temperature may be higher than the second average temperature by more than 20°C.
通常，发热体12a沿延伸方向的宽度一致，发热体12a在核心雾化区域A中的分布密度大于在核心雾化区域A外的边缘雾化区域B的分布密度。该分布密度在一些实施例中可以为，发热体12a在核心雾化区域A(或边缘雾化区域B)所占的面积与该核心雾化区域A(或边缘雾化区域B)的面积的比值。Usually, the width of the heating element 12a along the extension direction is uniform, and the distribution density of the heating element 12a in the core atomization area A is greater than that in the edge atomization area B outside the core atomization area A. The distribution density can be, in some embodiments, the ratio of the area occupied by the heating element 12a in the core atomization area A (or edge atomization area B) to the area of the core atomization area A (or edge atomization area B) ratio.
通常，发热体12a的40-90％分布在核心雾化区域A内。雾化面1111具有一第一宽度L1，核心雾化区域A沿第一宽度L1的延伸方向具有一第二宽度L2，第二宽度L2可以为第一宽度L1的30％-85％。优选地，第二宽度L2为第一宽度L1的2/3左右，通常其可以在63％-70％之间进行选择。Usually, 40-90% of the heating element 12a is distributed in the core atomization area A. The atomizing surface 1111 has a first width L1, and the core atomization area A has a second width L2 along the extending direction of the first width L1, and the second width L2 may be 30%-85% of the first width L1. Preferably, the second width L2 is about 2/3 of the first width L1, usually it can be selected between 63%-70%.
发热体12a的两端可分别设置有第一电极141、第二电极142，用于分别与电池装置的正负极电性连接。通常，边缘雾化区域B位于第一电极141、第二电极142所界定的空间内。Both ends of the heating element 12a can be respectively provided with a first electrode 141 and a second electrode 142 for electrically connecting with the positive and negative electrodes of the battery device respectively. Usually, the edge atomization area B is located in the space defined by the first electrode 141 and the second electrode 142 .
发热组件10可采取侧边进气或底部进气等进气方式。当发热组件10为侧边进气时，第一电极141、第二电极142可分别设置在雾化面1111的对角上，以优化侧边进气时烟雾的输送效果，有效防止第一电极141、第二电极142对气流的阻碍，避免烟雾滞留在雾化腔内，提高烟雾流动效率。The heat-generating component 10 can adopt air intake methods such as side air intake or bottom air intake. When the heat-generating component 10 uses side air intake, the first electrode 141 and the second electrode 142 can be respectively arranged on the opposite corners of the atomizing surface 1111, so as to optimize the delivery effect of the smoke during side air intake and effectively prevent the first electrode from 141. The second electrode 142 obstructs the air flow, preventing the smoke from staying in the atomizing chamber and improving the flow efficiency of the smoke.
发热体12a可以为发热膜或发热丝，其材质可以为金属。发热体12a的两端分别可设置有用于安装第一电极141、第二电极142的焊盘13。优选地，发热体12a为发热膜，其可采用电子浆料印刷在多孔体11的雾化面1111上。当多孔体11为烧结式结构时，发热体12a可通过烧结的方式与多孔体11一体成型。The heating element 12a can be a heating film or a heating wire, and its material can be metal. Both ends of the heating element 12a may be respectively provided with pads 13 for mounting the first electrode 141 and the second electrode 142 . Preferably, the heating body 12a is a heating film, which can be printed on the atomizing surface 1111 of the porous body 11 using electronic paste. When the porous body 11 has a sintered structure, the heating element 12 a can be integrally formed with the porous body 11 by sintering.
在一些实施例中，该发热膜可包括依次形成在雾化面1111上的第一覆盖膜和第二覆盖膜。第一覆盖膜、第二覆盖膜均可以为多孔膜。第一覆盖膜的材质可以为钛、锆、钛铝合金、钛锆合金、钛钼合金、钛铌合金、铁铝合金或钽铝合金等，第二覆盖膜的材质可以为铂、钯、钯铜合金、金银铂合金、金银合金、钯银合金或金铂合金等。优选地，第一覆盖膜为钛锆合金膜，第二覆盖膜为金银合金膜。In some embodiments, the heating film may include a first covering film and a second covering film sequentially formed on the atomizing surface 1111 . Both the first covering film and the second covering film may be porous films. The material of the first covering film can be titanium, zirconium, titanium-aluminum alloy, titanium-zirconium alloy, titanium-molybdenum alloy, titanium-niobium alloy, iron-aluminum alloy or tantalum-aluminum alloy, etc. The material of the second covering film can be platinum, palladium, palladium Copper alloy, gold-silver-platinum alloy, gold-silver alloy, palladium-silver alloy or gold-platinum alloy, etc. Preferably, the first covering film is a titanium-zirconium alloy film, and the second covering film is a gold-silver alloy film.

Preferably, the porous body 11 is made of porous ceramics. Porous ceramics are resistant to high temperature, have stable chemical properties, will not chemically react with smoke liquid, and as porous ceramics are insulators, they will not be electrically connected to the heating element 12a provided thereon to cause short circuit problems, which are convenient to manufacture and low in cost.
在一些实施例中，多孔陶瓷上的微孔的孔径范围可为1μm至100μm。多孔陶瓷的平均孔径可为10-35μm。优选地，多孔陶瓷的平均孔径为20-25μm。In some embodiments, the micropores on the porous ceramic may have a pore size ranging from 1 μm to 100 μm.

多孔陶瓷的孔隙率可为30％至70％，孔隙率是指多孔介质内的微小空隙的总体积与该多孔介质的总体积的比值。孔隙率的大小可以根据烟液的成分来调整，例如烟液的粘稠度大的，孔隙率则可以高一些，以保证导液效果。优选地，多孔陶瓷的孔隙率为50-60％。The porosity of the porous ceramic can be 30% to 70%, and the porosity refers to the ratio of the total volume of tiny voids in the porous medium to the total volume of the porous medium. The size of the porosity can be adjusted according to the composition of the e-liquid. For example, the viscosity of the e-liquid is high, and the porosity can be higher to ensure the liquid-conducting effect. Preferably, the porous ceramic has a porosity of 50-60%.

图5、7、9所示分别为图4、6、8所示的发热体加热3s后雾化面1111的温度场分布图。根据模拟实验表明，该发热体在核心雾化区域A的第一平均温度在120-200℃之间，边缘雾化区域B的在120℃以下。用户抽烟的时候，由于核心雾化区域A的温度足够高，烟液挥发的很快，从而使边缘雾化区域B的烟液向核心雾化区域A聚集，从而可避免漏液的发生，用户吸雾的时候不会吸入液滴，提升了用户体验。Figures 5, 7, and 9 are the distribution diagrams of the temperature field on the atomizing surface 1111 after heating the heating element shown in Figures 4, 6, and 8 for 3 seconds, respectively. According to the simulation experiment, the first average temperature of the heating element in the core atomization area A is between 120-200° C., and that in the edge atomization area B is below 120° C. When the user smokes, because the temperature of the core atomization area A is high enough, the liquid evaporates quickly, so that the liquid in the edge atomization area B gathers towards the core atomization area A, thereby avoiding the occurrence of liquid leakage. When inhaling mist, no liquid droplets will be inhaled, which improves the user experience.
进一步地，还可通过改变发热体的形状及长度，从而有效的降低干烧状态下发热体的温度，进而降低发热体与多孔体之间的热应力，进一步减少发热体和多孔体的变形量。通常，发热体的形状可配置成使得核心雾化区域A中单位长度发热体所需要加热的区域大小基本一致，避免多孔体的局部温度过高，来降低发热体与多孔体之间的热应力，减少发热体和多孔体的变形量。Furthermore, by changing the shape and length of the heating element, the temperature of the heating element in the dry burning state can be effectively reduced, thereby reducing the thermal stress between the heating element and the porous body, and further reducing the deformation of the heating element and the porous body . Usually, the shape of the heating element can be configured so that the size of the heated area per unit length of the heating element in the core atomization area A is basically the same, so as to avoid excessive local temperature of the porous body and reduce the thermal stress between the heating element and the porous body , Reduce the deformation of heating element and porous body.

Wherein, FIG. 1 shows a heating component 10e in some embodiments of the prior art, and the shape of the heating body 12e of the heating component 10e is similar to that of the heating body 12d shown in FIG. 10 . In this simulation experiment, the overall length of the heating element shown in Figure 1 is 9.05mm, and the width is 4.05mm; the overall length of the heating element shown in Figure 4 is 8mm, and the width is 4mm; the overall length of the heating element shown in Figure 10 is 10mm and a width of 6mm.
