本发明实施例涉及电子烟技术领域，尤其涉及一种雾化组件的制备方法及电子烟雾化器。The embodiments of the present invention relate to the technical field of electronic cigarettes, and in particular, to a preparation method of an atomizing component and an electronic cigarette atomizer.
背景技术Background technique
电子烟产品的核心部件为对电子烟油进行蒸发生成烟油气溶胶的雾化器，雾化器的功能主要是通过一能从储油腔吸取烟油并进行雾化的雾化组件实现；雾化组件具有一个用于吸取和传导烟油的多孔体、以及一设置于多孔体上用于对多孔体吸取和传导的烟油进行蒸发雾化的发热元件。其中，多孔体是一个自身内部具有毛细微孔的部件，可以通过内部的微孔进行烟油的浸润吸收和传导；而发热元件具有用于发热的发热部、以及导电引脚部分，发热部用于对多孔体传导来的烟油进行加热蒸发，形成供吸食的烟油气溶胶。The core component of the electronic cigarette product is the atomizer that evaporates the electronic cigarette oil to generate the cigarette oil aerosol. The function of the atomizer is mainly realized by an atomizing component that can absorb the cigarette oil from the oil storage cavity and atomize it; The atomizing assembly has a porous body for absorbing and conducting e-liquid, and a heating element arranged on the porous body for evaporating and atomizing the e-liquid absorbed and conducted by the porous body. Among them, the porous body is a component with micropores inside itself, which can infiltrate, absorb and conduct e-liquid through the internal micropores; and the heating element has a heating part for heating and a conductive pin part, which is used for the heating part. It heats and evaporates the smoke oil conducted by the porous body to form smoke oil aerosol for smoking.
目前通常雾化组件采用多孔陶瓷厚膜发热体，是以具有用于烟油吸取和传导微米级微孔的多孔陶瓷体为载体，通过丝网印刷工艺印制上印刷发热线路支承发热元件，通电之后发热元件对烟油进行雾化。这种多孔陶瓷体通常采用陶瓷浆料与造孔剂混合后再烧结的方式进行制备，烧结后的陶瓷体内具有大量微孔，从而用于烟油吸取和传导；整体制备过程可以实现自动化生产，工艺稳定性较高。At present, the atomization component usually uses a porous ceramic thick film heating element, which is a porous ceramic body with micro-scale pores for e-liquid absorption and conduction as a carrier, and a printed heating circuit is printed through a screen printing process to support the heating element. After that, the heating element atomizes the e-liquid. This kind of porous ceramic body is usually prepared by mixing ceramic slurry and pore-forming agent and then sintering. The sintered ceramic body has a large number of micropores, which are used for e-liquid absorption and conduction; the overall preparation process can realize automatic production, Process stability is high.
但采用以上方法制备的多孔陶瓷体在使用中存在一些不足：一方面制备工艺自身存在限制，采用将陶瓷粉料和造孔剂统一混料再烧结的过程，无法保证造孔剂的分散均匀性，使得制备的多孔陶瓷体的孔隙均匀度无法保证；同时由于烧结之前的陶瓷材料在浆料均匀混合阶段，浆料中的造孔剂是无规排布的，因此最终在烧结后的多孔体内部形成的微孔也是无规则排列的；而使用时烟油的传导路径是由若干微孔弯曲衔接组成，使得路径长度远大于从多孔陶瓷体的烟油吸取面到烟油雾化面的直线距离，从而限制了烟油的传导和雾化效率。另一方面，由于存在微孔，多孔陶瓷体表面相对较粗糙，导致印刷发热电路烧结在多孔陶瓷体表面后附着力较差，并存在高低凹凸不平和向微孔内渗透的情况，使得印刷发热电路的阻值稳定性和均匀性不足，使用时会出现电阻浮动不稳、甚至断裂无法导电的问题；同时在持续工作后由于热循环冲击效应，易造成印刷发热电路剥落。However, the porous ceramic body prepared by the above method has some deficiencies in use: on the one hand, the preparation process itself has limitations, and the uniformity of the dispersion of the pore-forming agent cannot be guaranteed by the process of uniformly mixing the ceramic powder and the pore-forming agent and then sintering them. , so that the pore uniformity of the prepared porous ceramic body cannot be guaranteed; at the same time, because the ceramic material before sintering is uniformly mixed in the slurry, the pore-forming agent in the slurry is randomly arranged, so the final porous body after sintering. The micropores formed inside are also randomly arranged; and the conduction path of the e-liquid is composed of several micropores that are bent and connected, so that the length of the path is much longer than the straight line from the e-liquid suction surface of the porous ceramic body to the e-liquid atomization surface. distance, thus limiting the conduction and atomization efficiency of e-liquid. On the other hand, due to the existence of micropores, the surface of the porous ceramic body is relatively rough, resulting in poor adhesion of the printed heating circuit after sintering on the surface of the porous ceramic body, and there are unevenness and penetration into the micropores, which makes the printing heat generation. The resistance stability and uniformity of the circuit are insufficient, and the resistance will be unstable during use, or even break and fail to conduct electricity; at the same time, after continuous operation, due to the thermal cycle shock effect, the printed heating circuit is likely to peel off.

具体实施方式Detailed ways
为了便于理解本发明，下面结合附图和具体实施方式，对本发明进行更详细的说明。In order to facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.
本发明实施例提出的电子烟雾化组件，以图1实施例所示的多层结构为例进行说明，电子烟雾化组件包括依次层叠设置的多孔陶瓷层10、致密陶瓷层20、以及发热元件30。多孔陶瓷层10和发热元件30分别层叠设置在致密陶瓷层20的两个相对表面上。其中，The electronic cigarette assembly proposed in the embodiment of the present invention is described by taking the multilayer structure shown in the embodiment of FIG. 1 as an example. The electronic cigarette assembly includes a porous ceramic layer 10 , a dense ceramic layer 20 , and a heating element 30 that are stacked in sequence. . The porous ceramic layer 10 and the heating element 30 are laminated on two opposite surfaces of the dense ceramic layer 20, respectively. in,
多孔陶瓷层10用于烟油吸取和传导；发热元件30通电后产生的热量，通过致密陶瓷层20作为介质传导至多孔陶瓷层10，从而对多孔陶瓷层10传导的烟油进行加热雾化。这一雾化组件所具有的多层结构中，致密陶瓷层20自身是致密的实心结构陶瓷，将发热元件30印刷在致密陶瓷层20上时线路更平整，无高低凹凸不平现象存在；同时发热元件30与致密陶瓷层20的结合性更强，电阻阻值的稳定性和均匀性有更高的保障，消除了发热元件30因线路凹凸不平导致电阻浮动不稳的跳阻、甚至断裂无法导电的问题，雾化器的整体工作稳定性和寿命能得到明显提高。The porous ceramic layer 10 is used for e-liquid absorption and conduction; the heat generated after the heating element 30 is energized is conducted to the porous ceramic layer 10 through the dense ceramic layer 20 as a medium, thereby heating and atomizing the e-liquid conducted by the porous ceramic layer 10 . In the multi-layer structure of this atomization assembly, the dense ceramic layer 20 itself is a dense solid structure ceramic, and the circuit is smoother when the heating element 30 is printed on the dense ceramic layer 20, and there is no uneven phenomenon; The element 30 has a stronger bond with the dense ceramic layer 20, and the stability and uniformity of the resistance value are more guaranteed, which eliminates the jump resistance of the heating element 30 due to the unevenness of the circuit, which causes the resistance to float unstable, or even breaks and cannot conduct electricity. The overall working stability and life of the atomizer can be significantly improved.
上述发热元件30可以是形成在致密陶瓷层20上的发热线路或发热膜，也可以是与该致密陶瓷层20烧结成一体结构的发热片、发热丝、发热网等。发热元件30的材料可以是具有适当阻抗的金属材料、金属合金、石墨、碳、导电陶瓷或其它陶瓷材料和金属材料的复合材料。适当的金属或合金材料包括镍、钴、锆、钛、镍合金、钴合金、锆合金、钛合金、镍铬合金、镍铁合金、铁铬合金、铁铬铝合金、钛合金、铁锰铝基合金或不锈钢等中的至少一种。作为其中一个实施例，发热元件30为发热线路层，在致密陶瓷层20上形成有一个或多个间隔分布的发热线路，发热线路的电阻材料可以选取具有特定电阻温度系数的金属或合金材料，例如正温度系数或负温度系数，这样发热线路既可以用来发热，又可以作为用来感测雾化组件实时温度的传感器。作为另一实施例，在致密陶瓷层20上至少形成有间隔分布在致密陶瓷层20表面上的第一发热线路和第二发热线路，第一发热线路和第二发热线路具有不同的电阻温度系数，第一发热线路用来发热，第二发热线路用来感测雾化组件的温度。The above-mentioned heating element 30 may be a heating circuit or a heating film formed on the dense ceramic layer 20 , or may be a heating sheet, heating wire, heating net, etc. sintered with the dense ceramic layer 20 to form an integral structure. The material of the heating element 30 may be a metal material, metal alloy, graphite, carbon, conductive ceramic or other composite material of ceramic material and metal material with suitable impedance. Suitable metal or alloy materials include nickel, cobalt, zirconium, titanium, nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel chromium alloys, nickel iron alloys, iron chromium alloys, iron chromium aluminum alloys, titanium alloys, iron manganese aluminum bases At least one of alloy or stainless steel, etc. As one of the embodiments, the heating element 30 is a heating circuit layer, and one or more heating circuits distributed at intervals are formed on the dense ceramic layer 20. The resistance material of the heating circuit can be selected from a metal or alloy material with a specific temperature coefficient of resistance, For example, a positive temperature coefficient or a negative temperature coefficient, so that the heating circuit can not only be used for heating, but also can be used as a sensor for sensing the real-time temperature of the atomizing component. As another embodiment, at least a first heating circuit and a second heating circuit spaced on the surface of the dense ceramic layer 20 are formed on the dense ceramic layer 20, and the first heating circuit and the second heating circuit have different resistance temperature coefficients , the first heating circuit is used to generate heat, and the second heating circuit is used to sense the temperature of the atomizing component.
基于以上雾化组件采用的层叠结构，在图1的块状结构实施例基础上，其他变形实施方式中雾化组件的产品形状可以变化为致密陶瓷层20与发热元件30的形状适配(如图3所示)、圆柱状、圆筒状(如图4所示的径向截面形状，多孔陶瓷层10的外表面被配置为吸油面a、内表面被配置为雾化面b)、T字形、扇形(如图5所示)、甚至各种曲面弧形结构的电子烟雾化组件。Based on the laminated structure adopted by the above atomizing assembly, on the basis of the block structure example shown in FIG. 1 , the product shape of the atomizing assembly in other modified embodiments can be changed to fit the shape of the dense ceramic layer 20 and the heating element 30 (such as 3), cylindrical shape, cylindrical shape (the radial cross-sectional shape shown in FIG. 4, the outer surface of the porous ceramic layer 10 is configured as an oil absorption surface a, and the inner surface is configured as an atomization surface b), T Shape, sector (as shown in Figure 5), and even various curved arc structures of electronic vaping components.
需要说明的是，陶瓷领域中，致密陶瓷即为实心的结构陶瓷，通常内部孔隙率低于3％，相比多孔陶瓷其内部无大量微孔。It should be noted that, in the field of ceramics, dense ceramics are solid structural ceramics, usually with an internal porosity of less than 3%. Compared with porous ceramics, they do not have a large number of micropores inside.
以上结构的电子烟雾化组件在使用时，可以进一步参见图2所示的方式，在雾化器A内，将多孔陶瓷层10沿层叠方向的两个相对表面分别配置为吸油面a和雾化面b使用。具体在图2中，多孔陶瓷层10与致密陶瓷层20相对的表面能接受致密陶瓷层20传导的热量，因此配置为雾化面b；多孔陶瓷层10与致密陶瓷层20相背的表面为裸露表面，因此配置为吸油面a；使用时，将吸油面a与雾化器A中储油腔存储的烟油直接或间接接触，从而对烟油进行吸取(图2中所示为吸油面a直接伸入至储油腔内与烟油直接接触，在其他的变化实施方式中可以采用通过烟油传递孔道与储油腔内的烟油间接接触)；多孔陶瓷层10通过微孔的毛细浸润将吸油面a吸取的烟油传导至雾化面b上受热雾化，生成烟油气溶胶从多孔陶瓷层10侧面沿箭头P方向逸出；气溶胶的侧面逸出在于，多孔体产品的尺寸大多约4～8mm的长宽、孔隙率通常50％～80％，当雾化面b被致密陶瓷层20完全包覆时，气溶胶能从多个侧面顺畅逸出而不会大量在内部滞留。而发热元件30通电后产生的热量，以致密陶瓷层20作为介质沿着图示箭头R的方向传导至雾化面b上，为烟油雾化提供热量。When the electronic cigarette assembly with the above structure is in use, the method shown in FIG. 2 can be further referred to. In the atomizer A, the two opposite surfaces of the porous ceramic layer 10 along the stacking direction are respectively configured as the oil absorption surface a and the atomization surface a. Use face b. Specifically in FIG. 2 , the surface opposite the porous ceramic layer 10 and the dense ceramic layer 20 can receive the heat conducted by the dense ceramic layer 20 , so it is configured as the atomizing surface b; the surface opposite the porous ceramic layer 10 and the dense ceramic layer 20 is The exposed surface is therefore configured as the oil-absorbing surface a; when in use, the oil-absorbing surface a is directly or indirectly in contact with the e-liquid stored in the oil storage chamber of the atomizer A, so as to absorb the e-liquid (the oil-absorbing surface is shown in Figure 2). a directly extending into the oil storage cavity and directly contacting the e-liquid, in other variant embodiments, indirect contact with the e-liquid in the oil storage cavity through the e-liquid transfer channel); the porous ceramic layer 10 passes through the capillary of the micropore The infiltration conducts the e-liquid absorbed by the oil absorbing surface a to the atomizing surface b and is heated and atomized, and the generated e-liquid aerosol escapes from the side of the porous ceramic layer 10 in the direction of the arrow P; the side escape of the aerosol lies in the size of the porous product. Most are about 4-8mm in length and width, and the porosity is usually 50%-80%. When the atomized surface b is completely covered by the dense ceramic layer 20, the aerosol can escape smoothly from multiple sides without a large amount of retention in the interior. . The heat generated after the heating element 30 is energized is conducted to the atomizing surface b along the direction of the arrow R in the figure by using the dense ceramic layer 20 as a medium to provide heat for the atomization of the e-liquid.
而在另一实施例图3所示的雾化组件工作时，热量沿着箭头R的方向从发热元件30通过致密陶瓷层20传导至雾化面b上对烟油进行雾化生成气溶胶；而由于致密陶瓷层20并无将雾化面b完全包覆，因此气溶胶具有更多的逸出部位，比如图3中箭头P所示的侧向逸出、以及从未被包覆的部位向下逸出。In another embodiment, when the atomizing assembly shown in FIG. 3 is working, heat is conducted along the direction of arrow R from the heating element 30 through the dense ceramic layer 20 to the atomizing surface b to atomize the e-liquid to generate aerosol; Since the dense ceramic layer 20 does not completely cover the atomized surface b, the aerosol has more escape parts, such as the lateral escape shown by the arrow P in FIG. 3 and the parts that are not covered escape down.
实施中，多孔陶瓷层10中含有的微孔孔径控制10～80μm范围，孔隙率在40％～70％范围内可调，使其为孔径大小和结构均一的多孔结构。致密陶瓷层20优选采用厚度控制在0.05～0.1mm范围，并且优选采用导热性能高的陶瓷，使其更利于热量传导，从而保证传导至雾化面b上的温度满足烟油雾化的需求。In practice, the pore size of the micropores contained in the porous ceramic layer 10 is controlled in the range of 10-80 μm, and the porosity is adjustable in the range of 40%-70%, so that it is a porous structure with uniform pore size and structure. The thickness of the dense ceramic layer 20 is preferably controlled in the range of 0.05-0.1 mm, and ceramics with high thermal conductivity are preferably used to make it more conducive to heat conduction, thereby ensuring that the temperature transmitted to the atomizing surface b meets the needs of e-liquid atomization.
同时，基于现有更加精准的产品性质要求，以上实施中采用多孔陶瓷层10内的微孔大致是朝致密陶瓷层20方向延伸排布的，即大致具有从吸油面a朝雾化面b延伸排布的特点。通过这一种大致的方向一致性的特点，可以使得烟油在多孔陶瓷层10内的传导大致为直线传导，相比现有的无微孔方向性的多孔陶瓷体，能大大提升烟油的传导效率。微孔的大致方向一致性可以通过以下所描述的3D打印制备获得；或者是其他能形成多孔陶瓷微孔方向性的方式制备获得。At the same time, based on the existing more precise product property requirements, the micropores in the porous ceramic layer 10 are generally arranged in the direction of the dense ceramic layer 20 in the above implementation, that is, the micropores generally extend from the oil absorption surface a to the atomization surface b. Arrangement features. Through this feature of roughly directional consistency, the conduction of e-liquid in the porous ceramic layer 10 can be made to be approximately straight. conduction efficiency. The approximate directional uniformity of the micropores can be obtained by 3D printing as described below; or by other methods that can form the directionality of the porous ceramic micropores.

Correspondingly, the above porous ceramic layer 10 and dense ceramic layer 20 are formed; wherein, the porous ceramic layer 10 is formed by sintering the porous ceramic matrix layer 10a, and the dense ceramic layer 20 is formed by sintering the dense ceramic matrix layer 20a. After the first sintering is completed and each ceramic layer has been solidified and formed, the substrate S can be peeled off to expose the surface of the dense ceramic layer 20 for subsequent preparation of the heating element 30;
S40，按照所需的发热元件30的形状，将发热材料通过丝网印刷工艺在致密陶瓷层20表面上形成发热线路30a，发热线路30a可以是间隔分布于致密陶瓷层20上的一个或多个，如图8所示；S40, according to the desired shape of the heating element 30, the heating material is screen-printed to form a heating circuit 30a on the surface of the dense ceramic layer 20, and the heating circuit 30a may be one or more spaced apart on the dense ceramic layer 20 , as shown in Figure 8;
S50，再将图8所示印刷有发热线路30a的陶瓷体进行第二次烧结，使发热线路30a烧结形成发热元件30，即获得图1所示的电子烟雾化组件。S50 , sintering the ceramic body printed with the heating circuit 30 a shown in FIG. 8 for a second time, so that the heating circuit 30 a is sintered to form the heating element 30 , that is, the electronic cigarette assembly shown in FIG. 1 is obtained.
细节实施中，步骤S10中采用的衬底S用于在进行3D打印时作为打印材料的承载基体，后续待陶瓷粉料烧结成型之后可以剥离去除。实施中衬底S选择能耐受烧结温度、且不会引起陶瓷层表面产生不良形变的耐温材料。比如衬底S可以采用钨钢片、耐高温玻璃片、铁镍合金片等等均可。同时，对获取的衬底S，进行3D打印之前还可以进行表面钝化处理，使表面应力降低，从而利于后续顺畅剥离。表面钝化处理的方式可以包括表面氧化、沉积惰性层等。In the detailed implementation, the substrate S used in step S10 is used as a carrier substrate of the printing material during 3D printing, and can be peeled off and removed after the ceramic powder is sintered and formed. In practice, the substrate S is selected from a temperature-resistant material that can withstand the sintering temperature and will not cause undesirable deformation on the surface of the ceramic layer. For example, the substrate S can be a tungsten steel sheet, a high temperature resistant glass sheet, an iron-nickel alloy sheet, or the like. At the same time, the obtained substrate S can also be subjected to surface passivation treatment before 3D printing, so as to reduce the surface stress and facilitate subsequent smooth peeling. The surface passivation treatment can include surface oxidation, deposition of an inert layer, and the like.
步骤S20体现的过程是以电子烟雾化组件产品中多孔陶瓷层10和致密陶瓷层20的层叠结构为打印模型，控制打印设备分别用不同的陶瓷粉料打印生成陶瓷驱体；具体，The process embodied in step S20 uses the laminated structure of the porous ceramic layer 10 and the dense ceramic layer 20 in the electronic cigarette assembly product as a printing model, and controls the printing equipment to print with different ceramic powders to generate a ceramic drive body; specifically,
步骤S21将不含有造孔剂的致密陶瓷打印粉料通过3D打印在衬底S上，形成致密陶瓷驱体层20a，后续烧结即形成致密陶瓷层20。基于致密陶瓷层20需要同时具备良好的致密性使印刷发热层30平整接合、以及良好的导热性实现对印刷发热层30的温度传导的性能，在该步骤实施中，致密陶瓷打印粉料优选采用热导率较高的硬质陶瓷材料，比如碳化硅或氮化铝等。In step S21 , the dense ceramic printing powder without pore-forming agent is 3D printed on the substrate S to form the dense ceramic drive body layer 20 a , and the dense ceramic layer 20 is formed by subsequent sintering. Based on the fact that the dense ceramic layer 20 needs to have good compactness to make the printed heating layer 30 evenly bonded, and good thermal conductivity to achieve the performance of temperature conduction to the printed heating layer 30, in the implementation of this step, the dense ceramic printing powder is preferably used. Hard ceramic materials with high thermal conductivity, such as silicon carbide or aluminum nitride.
步骤S22进一步再控制打印设备的油墨喷头在Z轴高度方向上逐步提升高度，打印生成层叠的多孔陶瓷驱体层10a，后续烧结即为多孔陶瓷层10。该步骤中所采用的多孔陶瓷打印粉料含有造孔剂成分，用于在烧结时形成烟油传导的微孔。多孔陶瓷打印粉料的主料采用氧化铝、氧化锆、碳化硅、氮化硅、氮化铝中的一种或多种；同时根据所需制备的多孔陶瓷层30的性能要求，可以通过调整多孔陶瓷打印粉料中造孔剂的含量和颗粒尺寸大小，改变最终获得的多孔陶瓷层10的微孔孔隙率和孔径参数。实施中，优选在多孔陶瓷打印粉料中造孔剂所占体积分数为40％～70％；造孔剂的颗粒尺寸控制在10～80μm范围。造孔剂可以采用淀粉、木屑、PMMA(聚甲基丙烯酸甲酯)微球、石墨粉中的至少一种。Step S22 further controls the ink nozzle of the printing device to gradually increase the height in the Z-axis height direction, and prints to generate a laminated porous ceramic matrix layer 10a, and the subsequent sintering is the porous ceramic layer 10 . The porous ceramic printing powder used in this step contains a pore-forming agent component, which is used to form micropores for e-liquid conduction during sintering. The main material of the porous ceramic printing powder is one or more of alumina, zirconia, silicon carbide, silicon nitride, and aluminum nitride; at the same time, according to the performance requirements of the porous ceramic layer 30 to be prepared, it can be adjusted by adjusting The content and particle size of the pore-forming agent in the porous ceramic printing powder change the microporosity and pore size parameters of the finally obtained porous ceramic layer 10 . In practice, it is preferable that the volume fraction of the pore-forming agent in the porous ceramic printing powder is 40%-70%; the particle size of the pore-forming agent is controlled in the range of 10-80 μm. The pore-forming agent can be at least one of starch, wood chips, PMMA (polymethyl methacrylate) microspheres, and graphite powder.
基于在多孔陶瓷打印粉料和致密陶瓷打印粉料在烧结的过程中，不同元素系的陶瓷粉料，烧结时产生的烧蚀率/形变量一致性、烧结之后的结合性都不如同元素系的陶瓷粉料，因此在优选实施中采用多孔陶瓷打印粉料的陶瓷主料至少包含与致密陶瓷打印粉料同元素系的陶瓷粉料。比如，当致密陶瓷层材质选用氧化铝粉料制备时，对应多孔陶瓷层可以采用氧化铝/氮化铝等铝系陶瓷，或者用以上铝系陶瓷与其他的不同元素系(如氧化锆或碳化硅)等混合材质。Based on the fact that in the sintering process of porous ceramic printing powder and dense ceramic printing powder, ceramic powders of different element systems have different ablation rate/deformation consistency during sintering and binding after sintering. Therefore, in a preferred implementation, the ceramic main material of the porous ceramic printing powder contains at least the ceramic powder of the same element series as the dense ceramic printing powder. For example, when the dense ceramic layer is made of alumina powder, the corresponding porous ceramic layer can be made of aluminum-based ceramics such as alumina/aluminum nitride, or the above aluminum-based ceramics and other different element systems (such as zirconia or carbide) can be used. Silicon) and other mixed materials.
同时，根据致密陶瓷打印粉料和多孔陶瓷打印粉料烧结后形成的对象不同，致密陶瓷打印粉料优选采用0.5～2μm的粒径，使其具有更加致密平整的无孔结构形态；而多孔陶瓷打印粉料中的主料可以采用10～50μm的粒径，更利于配合造孔剂形成良好的多孔结构形态。At the same time, according to the different objects formed after sintering the dense ceramic printing powder and the porous ceramic printing powder, the dense ceramic printing powder preferably adopts a particle size of 0.5-2 μm, so that it has a denser and smoother non-porous structure. The main material in the printing powder can have a particle size of 10-50 μm, which is more conducive to the formation of a good porous structure with the pore-forming agent.
以上步骤S20打印完成之后，即可按照步骤S30将打印的陶瓷驱体进行第一次烧结，第一次烧结的过程可以采用通常陶瓷烧结方法进行：先从室温升温至600～1000℃，接着升温至1200～1500℃保温2～5h即可。After the printing in the above step S20 is completed, the printed ceramic drive body can be sintered for the first time according to the step S30. The first sintering process can be carried out by using the usual ceramic sintering method: firstly, the temperature is raised from room temperature to 600-1000°C, and then the temperature is raised. To 1200 ~ 1500 ℃ insulation 2 ~ 5h can be.
以上实施例采用的制备方法，通过3D打印、烧结制备的多孔陶瓷层10，相比通常混料、烧结的方式制备的多孔体，具有两个方面的优势；一方面陶瓷粉料是通过3D打印机的油墨喷头逐渐微量喷出，造孔剂分散度更加均匀，能提高后续烧结形成，能解决搅拌混料工艺条件限制引起的均匀性不足的缺陷；微孔的均匀度通过扫描电镜分析可以非常显著的看出。另一方面，由于打印设备进行3D打印的过程是按照设定的打印模型，在Z轴方向上逐步提升油墨喷头的打印高度逐层打印实现(如图7所示)；因此粉料从油墨喷头微量逐步喷出后，致孔剂在打印形成的驱体层中大致是沿着Z轴方向排布，烧结之后形成的微孔大致具有沿Z轴方向上延伸的方向性。因此，利用这一特点，按照如图2的配置方式，将多孔陶瓷层10的上表面配置为吸油面a使用，那么烟油在多孔陶瓷层10内的浸润传导大致是沿着Z轴方向进行，相比在混料烧结制备的无规微孔的多孔体中的浸润传导，具有更快的效率。The preparation method adopted in the above embodiment, the porous ceramic layer 10 prepared by 3D printing and sintering has two advantages compared with the porous body prepared by the usual mixing and sintering method; on the one hand, the ceramic powder is produced by 3D printer The ink nozzle gradually ejects a small amount, the dispersion of the pore-forming agent is more uniform, the subsequent sintering formation can be improved, and the defect of insufficient uniformity caused by the limitation of the stirring and mixing process conditions can be solved; the uniformity of the micropores can be analyzed by scanning electron microscopy. seen. On the other hand, since the 3D printing process of the printing equipment is based on the set printing model, the printing height of the ink nozzle is gradually increased in the Z-axis direction to achieve layer-by-layer printing (as shown in Figure 7); therefore, the powder is removed from the ink nozzle. After a small amount is gradually ejected, the porogen is generally arranged along the Z-axis direction in the drive body layer formed by printing, and the micropores formed after sintering generally have a directionality extending along the Z-axis direction. Therefore, taking advantage of this feature, the upper surface of the porous ceramic layer 10 is used as the oil absorption surface a according to the configuration as shown in FIG. 2 , then the infiltration and conduction of the e-liquid in the porous ceramic layer 10 is generally carried out along the Z-axis direction. , with a faster efficiency than the infiltration conduction in the random microporous porous body prepared by hybrid sintering.
步骤S30烧结之后，剥离衬底使致密陶瓷层20的表面裸露出来，从而用于后续印刷发热线路30的制备。制备过程如步骤S40和S50所描述，将具有致密陶瓷层20和多孔陶瓷层30的陶瓷体按照图8所示，通过负压等方式固定在一工作台B上，在致密陶瓷层20的表面通过丝网印刷的方式形成发热线路30a，然后再整体置于煅烧炉中进行第二次烧结处理，即使发热线路30a烧结形成发热元件30。这里印刷发热线路30a所采用的材质可以是纯镍、镍铬合金、镍铁合金、铁铬合金、铁铬铝合金、钛合金或不锈钢等，制备中将这些材质的驱体粉末与烧结助剂均匀混合成浆料，然后按照所需的形状在致密陶瓷层20表面进行印刷、干燥、烧结即可。本次烧结的过程采用真空炉中以5～10℃/min的速率升温至800～1100℃后，保温0.5～4小时，本次烧结过程中真空度控制在1～0.01Pa，烧结之后即得到表面均匀、电阻合适的发热元件30。After the sintering in step S30 , the substrate is peeled off to expose the surface of the dense ceramic layer 20 , so as to be used for the preparation of the subsequent printed heating circuit 30 . The preparation process is as described in steps S40 and S50. As shown in FIG. 8, the ceramic body with the dense ceramic layer 20 and the porous ceramic layer 30 is fixed on a workbench B by means of negative pressure, etc., on the surface of the dense ceramic layer 20. The heating circuit 30 a is formed by screen printing, and then the whole is placed in a calcining furnace for a second sintering process, even if the heating circuit 30 a is sintered to form the heating element 30 . Here, the material used for printing the heating circuit 30a can be pure nickel, nickel-chromium alloy, nickel-iron alloy, iron-chromium alloy, iron-chromium-aluminum alloy, titanium alloy or stainless steel, etc. During the preparation, the driver powder and sintering aid of these materials are uniformly mixed After mixing into a slurry, printing, drying and sintering can be performed on the surface of the dense ceramic layer 20 according to the desired shape. This sintering process adopts a vacuum furnace to heat up to 800-1100 ℃ at a rate of 5-10 ℃/min, and keep the temperature for 0.5-4 hours. A heating element 30 with a uniform surface and suitable resistance.
以上发热元件30通过印刷方式在无微孔的致密陶瓷层20表面制备，发热元件30更平整、无高低凹凸不平现象存在。同时，制备的发热元件30与致密陶瓷层20的结合性更强，电阻阻值的稳定性和均匀性有更高的保障，不会出现电阻浮动不稳定甚至断裂的问题。The above heating element 30 is prepared by printing on the surface of the dense ceramic layer 20 without micropores, and the heating element 30 is smoother and free from unevenness. At the same time, the prepared heating element 30 has stronger bonding with the dense ceramic layer 20 , the stability and uniformity of the resistance value are more guaranteed, and the problem of resistance floating instability or even breakage will not occur.
需要说明的是以上实施例的制备过程中，是将陶瓷体与印刷发热线路分两次烧结的方式进行；而不采用将具有致密陶瓷驱体层20a和多孔陶瓷驱体层10a的陶瓷驱体直接剥离衬底S、再印刷上发热线路30a后进行一并烧结。分两次烧结的目的是保证通过第一次烧结使致密陶瓷驱体层20a形成致密陶瓷层20后表面结构固化为平整致密形态，那么后续发热线路30a第二次烧结时，不会存在同时烧结时致密陶瓷驱体层20a自身表面烧蚀形变而引起发热元件30凹凸形变的问题；从而可以防止采用一并烧结的做法时，致密陶瓷驱体层20a形成致密陶瓷层20的过程会产生自身表面烧蚀形变，而影响发热元件30的平整性和结合性。It should be noted that in the preparation process of the above embodiment, the ceramic body and the printed heating circuit are sintered twice; instead of using a ceramic drive body having a dense ceramic drive body layer 20a and a porous ceramic drive body layer 10a The substrate S is directly peeled off, and the heating circuit 30a is printed again, and then sintered together. The purpose of sintering in two times is to ensure that the dense ceramic drive body layer 20a is formed into the dense ceramic layer 20 through the first sintering, and then the surface structure is solidified into a flat and dense shape, so that there will be no simultaneous sintering during the second sintering of the subsequent heating circuit 30a. The problem of concave and convex deformation of the heating element 30 caused by the ablation and deformation of the surface of the dense ceramic drive body layer 20a at the same time can prevent the formation of the dense ceramic drive body layer 20a in the process of forming the dense ceramic body layer 20 when the method of sintering is adopted. The ablation deformation affects the flatness and bonding of the heating element 30 .
进一步在实施中，步骤S20决定3D打印设备打印过程的打印模型，是根据最终所需的电子烟雾化组件形状进行设计的。以最终所需的电子烟雾化组件形状为基础，通过3D打印软件程序编程，可设计出各种含有上述层级结构吻合的3D打印模型。Further in the implementation, step S20 determines the printing model of the 3D printing device printing process, which is designed according to the final shape of the electronic cigarette assembly. Based on the final shape of the vaping components required, through the 3D printing software program programming, various 3D printing models containing the above-mentioned hierarchical structures can be designed.
而在图1实施例的打印模型之外，在其他更多的雾化组件形状需求时，制备时对应调整打印模型控制打印设备进行3D打印制备陶瓷驱体即可。而在这些更多样的雾化组件形状制备时，需要保持3D打印方向的Z轴方向为多孔陶瓷层10与致密陶瓷层20的层叠方向一致，以保证最终生成的多孔陶瓷层10内的微孔方向具有沿层叠方向的一致性。比如，当制备图4所示的环状雾化组件时，3D打印过程则可以采用一筒状衬底作为载体，然后沿着径向方向用不同的陶瓷粉料分别在筒状衬底上打印生成相互层叠的致密陶瓷驱体层20a和多孔陶瓷驱体层10a，后续烧结后的多孔陶瓷层10具有沿径向方向的大致方向一致性。按照这一方向性分别将多孔陶瓷层10的相对表面配置为吸油面a和雾化面b使用，则能提升烟油传导和雾化效率。In addition to the printing model in the embodiment of FIG. 1 , when other shapes of the atomizing components are required, it is sufficient to adjust the printing model and control the printing device to perform 3D printing to prepare the ceramic drive body during preparation. In the preparation of these more diverse shapes of atomizing components, it is necessary to keep the Z-axis direction of the 3D printing direction consistent with the lamination direction of the porous ceramic layer 10 and the dense ceramic layer 20 to ensure the final generation of the porous ceramic layer 10. The hole direction has uniformity along the stacking direction. For example, when preparing the annular atomizing assembly shown in Figure 4, the 3D printing process can use a cylindrical substrate as a carrier, and then print on the cylindrical substrate with different ceramic powders in the radial direction. The dense ceramic matrix layer 20a and the porous ceramic matrix layer 10a stacked on each other are generated, and the porous ceramic layer 10 after subsequent sintering has approximately uniform direction in the radial direction. According to this directionality, the opposite surfaces of the porous ceramic layer 10 are configured as the oil absorption surface a and the atomization surface b, respectively, so that the e-liquid conduction and atomization efficiency can be improved.
进一步，以上步骤S20实施中层叠打印次序采用的是最优选的次序，先在衬底S上先打印致密陶瓷驱体层20a，再层叠打印多孔陶瓷驱体层10a。致密陶瓷驱体层20a的一表面始终结合于衬底S上，后续第一次烧结时，衬底S可以起到表面模型的作用，最大化地减低在烧结的过程致密陶瓷驱体层20a表面的烧蚀形变，从而保证表面的平整；而在后续印刷发热元件30时，高的表面平整性能更加利于提升发热元件30的结合性和平整稳定性。而相比这一优选的打印次序，在其他变形实施例中，可以采用将以上次序颠倒的方式进行，采用：Further, in the implementation of the above step S20, the stacking printing sequence adopts the most preferable sequence, firstly printing the dense ceramic matrix layer 20a on the substrate S, and then stacking and printing the porous ceramic matrix layer 10a. One surface of the dense ceramic matrix layer 20a is always bonded to the substrate S. During the first sintering, the substrate S can play the role of a surface model to minimize the surface of the dense ceramic matrix layer 20a during the sintering process. Therefore, when the heating element 30 is subsequently printed, the high surface flatness performance is more conducive to improving the bonding and flatness stability of the heating element 30 . Compared with this preferred printing order, in other variant embodiments, the above order may be reversed, and the following may be used:
S21，先以含有造孔剂成分的多孔陶瓷打印粉料在衬底S上进行3D打印，形成多孔陶瓷驱体层10a，如图9所示；S21, 3D printing is first performed on the substrate S with the porous ceramic printing powder containing the pore-forming agent to form the porous ceramic driving body layer 10a, as shown in FIG. 9 ;
S22，再以不含造孔剂成分的致密陶瓷打印粉料在多孔陶瓷驱体层10a上继续打印，生成层叠的致密陶瓷驱体层20a，如图10所示，即获得陶瓷驱体；S22, continue printing on the porous ceramic drive body layer 10a with the dense ceramic printing powder that does not contain a pore-forming agent to generate a laminated dense ceramic drive body layer 20a, as shown in FIG. 10, that is, a ceramic drive body is obtained;
S30，将步骤S22的陶瓷驱体进行第一次烧结，然后将衬底S从烧结形成的多孔陶瓷层10上进行剥离。S30, the ceramic drive body of step S22 is sintered for the first time, and then the substrate S is peeled off from the porous ceramic layer 10 formed by sintering.
采用这一次序打印烧结的陶瓷体，相比前一优选打印次序，致密陶瓷层20的表面平整度略有降低，但相比多孔陶瓷层10的粗糙表面仍具有非常大的提升；后续再印刷制备发热元件30时也具有结合性和稳定性的良好提升。Using this order to print the sintered ceramic body, compared with the previous preferred printing order, the surface flatness of the dense ceramic layer 20 is slightly reduced, but it is still greatly improved compared to the rough surface of the porous ceramic layer 10; subsequent re-printing The heat-generating element 30 is also produced with a good improvement in bondability and stability.
