本发明涉及雾化领域，更具体地说，涉及一种气溶胶形成装置及其加热组件。The present invention relates to the field of atomization, and more specifically, to an aerosol forming device and a heating component thereof.

The heating method of existing heat-not-burn aerosol forming devices is usually tubular peripheral heating or central embedded heating. Tubular peripheral heating means that the heating tube surrounds the aerosol-forming matrix to heat the aerosol-forming matrix. Central embedded heating means that the heating component is inserted into the aerosol-forming matrix to heat the aerosol-forming matrix. At present, the heating components of center-embedded heating devices are generally chip-type or needle-type. The preparation method is to screen-print resistance heating circuits on a metal or ceramic substrate and then cover them with a glaze layer for firing. When both ends of the resistance heating circuit of the heating element are energized, the heating element heats up and bakes the aerosol to form a matrix, producing aerosol for the user to inhale.

1、通电时只在电阻发热线路上产生热量，热场均匀性差，对气溶胶形成基质烘烤不充分；1. When energized, heat is only generated on the resistance heating circuit, the uniformity of the thermal field is poor, and the aerosol-forming matrix is not fully baked;
2、由于制备方法的限制，加热组件为多层结构，强度不高，存在断裂失效风险；2. Due to the limitations of the preparation method, the heating component has a multi-layer structure, which is not strong enough and has the risk of fracture and failure;
3、为了保证在使用过程中阻值稳定，印刷电阻发热线路使用的材料为贵金属浆料，成本高，且在产品寿命终止后回收不当易产生环境污染。3. In order to ensure stable resistance value during use, the material used in printed resistor heating circuits is precious metal slurry, which is costly and may cause environmental pollution if improperly recycled after the end of product life.

图1-3示出了本发明第一实施例中的加热组件10，该加热组件10为针状，其包括发热体11以及分别与发热体11的两端连接的第一电极14和第二电极15。1-3 show a heating component 10 in the first embodiment of the present invention. The heating component 10 is needle-shaped and includes a heating element 11 and a first electrode 14 and a second electrode connected to two ends of the heating element 11 respectively. Electrode 15.
发热体11用于***到气溶胶形成基质内以对气溶胶形成基质进行加热，其可采用导电陶瓷制成并具有柱状外形。陶瓷材料环保无污染，发热体11可直接与气溶胶形成基质接触。采用导电陶瓷作为发热体11，发热体11为一体式结构，结构强度高，通电时整个发热体11均在发热，高温度段在热场中占比高，从而能快速烘烤气溶胶形成基质，气溶胶生成迅速，且气溶胶香味浓郁。此外，通电时导电陶瓷为均匀的体发热，温度场均匀且稳定性好，不易受外部因素影响，保证每次更换气溶胶形成基质均能有一致性较好的抽吸体验。发热体11采用柱状设计，柱状发热体11周圈热场相同，使气溶胶形成基质烘烤均匀，烘烤充分无死区，且柱状发热体11周圈热场无高温点，保证气溶胶香气醇正且无杂味焦味。The heating element 11 is used to be inserted into the aerosol-forming matrix to heat the aerosol-forming matrix. It can be made of conductive ceramics and has a columnar shape. Ceramic materials are environmentally friendly and pollution-free, and the heating element 11 can directly contact the aerosol to form a matrix. Conductive ceramics are used as the heating element 11. The heating element 11 is an integrated structure with high structural strength. The entire heating element 11 is generating heat when the electricity is energized. The high temperature section accounts for a high proportion in the thermal field, so that the aerosol can be quickly baked to form a matrix. , aerosols are generated quickly, and the aerosols have a strong fragrance. In addition, when energized, the conductive ceramic generates uniform body heat, the temperature field is uniform and stable, and is not easily affected by external factors, ensuring a consistent suction experience every time the aerosol-forming matrix is replaced. The heating element 11 adopts a columnar design. The thermal field of the 11-circumference circle of the columnar heating element is the same, so that the aerosol-forming matrix is baked evenly and fully baked without dead zones. The thermal field of the 11-circumference columnar heating element has no high-temperature spots, ensuring the aroma of the aerosol. It is mellow and has no burnt smell.
发热体11可通过高温烧结制备得到，高温烧结制备得到的发热体11的结构紧凑致密不容易被破坏，阻值稳定性较好。在一些实施例中，发热体11可以为金属陶瓷，该金属陶瓷为金属和陶瓷的复合氧化物，其包括陶瓷相和金属相。该金属相可以为Ni、Fe、Cu、Co和不锈钢中的一种，或者它们之间任意的组合物（包括合金）。该金属相不包含贵金属材料，因而成本较低。在其他实施例中，在不考虑成本的情况下，该金属相也可包括贵金属材料。该陶瓷相的加入有两个作用：一是调控金属陶瓷的电阻率，二是改善金属陶瓷的机械性能。陶瓷相可以为氧化铝、氧化锆、氧化铈、氧化钛、氧化锰、氧化铬、氧化铁、氧化镍、氧化钇、氧化镧、氧化钐、氧化铌、氧化钼、氧化锌中的一种或者它们之间任意的组合物。该金属陶瓷的电阻率与金属相和陶瓷相的材料成分及它们各自粉体的形貌、金属相与陶瓷相的比例以及烧结致密度等参数有关。通过控制相关参数可以实现对该金属陶瓷的电阻率进行调控。The heating element 11 can be prepared by high-temperature sintering. The heating element 11 prepared by high-temperature sintering has a compact and dense structure that is not easily damaged and has good resistance stability. In some embodiments, the heating element 11 may be a cermet, which is a composite oxide of metal and ceramic, including a ceramic phase and a metal phase. The metal phase can be one of Ni, Fe, Cu, Co and stainless steel, or any combination (including alloy) between them. This metallic phase does not contain precious metal materials and therefore is less expensive. In other embodiments, the metallic phase may also include noble metal materials without considering cost. The addition of the ceramic phase has two functions: one is to regulate the resistivity of the cermet, and the other is to improve the mechanical properties of the cermet. The ceramic phase may be one of aluminum oxide, zirconium oxide, cerium oxide, titanium oxide, manganese oxide, chromium oxide, iron oxide, nickel oxide, yttrium oxide, lanthanum oxide, samarium oxide, niobium oxide, molybdenum oxide, zinc oxide or Any combination between them. The resistivity of the cermet is related to the material composition of the metal phase and the ceramic phase, the morphology of their respective powders, the ratio of the metal phase to the ceramic phase, and the sintering density and other parameters. The resistivity of the cermet can be controlled by controlling relevant parameters.
进一步地，还可选用适当的元素种类和掺杂量对陶瓷相的陶瓷本体材料进行掺杂取代，目的在于适当提高陶瓷相的结构稳定性和改善其机械性能。例如，采用钇对氧化锆进行掺杂，可以提高氧化锆的相结构稳定性；采用锆对氧化铝进行掺杂，可以提高氧化铝的韧性。值得注意的是，不管使用什么元素和使用多少掺杂量对陶瓷本体材料进行掺杂取代，都在本发明的保护范围内。Furthermore, the ceramic bulk material of the ceramic phase can also be doped and replaced with appropriate element types and doping amounts, in order to appropriately enhance the structural stability of the ceramic phase and improve its mechanical properties. For example, doping zirconia with yttrium can improve the phase structure stability of zirconia; doping alumina with zirconium can improve the toughness of alumina. It is worth noting that no matter what element is used and how much doping amount is used for doping and substitution of the ceramic body material, it is within the protection scope of the present invention.
发热体11具有沿轴向相对设置的第一端111和第二端112，在本实施例中，该第一端111为发热体11的上端，该第二端112为发热体11的下端。根据用途需求，发热体11从第二端112至第一端111的电阻率可一致或者也可不一致。例如，发热体11从第二端112至第一端111的电阻率相同，以使发热均匀。再例如，发热体11第一端111的电阻率大于发热体11第二端112的电阻率，以适用于第一端111温度较高、第二端112温度较低的需求。又例如，发热体11从第一端111至第二端112的电阻率逐渐减小，以适用于第一端111至第二端112的温度逐渐降低的需求。The heating element 11 has a first end 111 and a second end 112 oppositely arranged along the axial direction. In this embodiment, the first end 111 is the upper end of the heating element 11 and the second end 112 is the lower end of the heating element 11 . According to application requirements, the resistivity of the heating element 11 from the second end 112 to the first end 111 may be consistent or inconsistent. For example, the resistivity of the heating element 11 from the second end 112 to the first end 111 is the same to ensure uniform heating. For another example, the resistivity of the first end 111 of the heating element 11 is greater than the resistivity of the second end 112 of the heating element 11 to meet the requirement that the temperature of the first end 111 is higher and the temperature of the second end 112 is lower. For another example, the resistivity of the heating element 11 gradually decreases from the first end 111 to the second end 112 to meet the requirement that the temperature of the first end 111 to the second end 112 gradually decreases.
第一电极14和第二电极15用于外接外部电源，其分别与发热体11的第一端111和第二端112连通。第一电极14、第二电极15均可通过涂覆导电浆料或钎焊等方式与发热体11直接导通，也可通过一个中间导电件与发热体11间接导通。当通过第一电极14和第二电极15在发热体11的上下两端施加电压时，发热体11内有电流通过而产生热量，实现对气溶胶形成基质的烘烤加热。该上下电极的输入形式，可保证发热体11上无需进行开缝设计，从而提高加热均匀性，对气溶胶形成基质的烘烤均匀性好。第一电极14和第二电极15具有低电阻率，其在一些实施例中可以为电极丝，例如铝丝或银丝。The first electrode 14 and the second electrode 15 are used to connect to an external power source, and are respectively connected to the first end 111 and the second end 112 of the heating element 11 . Both the first electrode 14 and the second electrode 15 can be directly connected to the heating element 11 by coating conductive paste or soldering, or can be indirectly connected to the heating element 11 through an intermediate conductive member. When a voltage is applied to the upper and lower ends of the heating element 11 through the first electrode 14 and the second electrode 15, a current passes through the heating element 11 to generate heat, thereby achieving baking and heating of the aerosol-forming substrate. The input form of the upper and lower electrodes can ensure that there is no need for slit design on the heating element 11, thereby improving the heating uniformity and achieving good baking uniformity of the aerosol-forming substrate. The first electrode 14 and the second electrode 15 have low resistivity, which in some embodiments may be electrode wires, such as aluminum wires or silver wires.
进一步地，发热体11可以为内部中空的管状，其内沿纵向（即发热体11的轴向）贯穿形成有一通孔110。该加热组件10还可包括穿设于该通孔110的支撑杆12。支撑杆12可增强加热组件10的整体强度，防止加热组件10在使用过程中发生断裂。Furthermore, the heating element 11 may be in the shape of a hollow tube, with a through hole 110 formed therethrough in the longitudinal direction (ie, the axial direction of the heating element 11 ). The heating component 10 may further include a support rod 12 extending through the through hole 110 . The support rod 12 can enhance the overall strength of the heating component 10 and prevent the heating component 10 from breaking during use.
支撑杆12可包括收容于通孔110中的杆部121以及与杆部121的上端连接并位于通孔110外的头部122，加热组件10经由头部122***到气溶胶形成基质中。该头部122可具有冠状结构，在加热组件10***到气溶胶形成基质的过程中，该冠状结构可保护管状发热体11，避免管状发热体11与气溶胶形成基质之间的摩擦力过大而损坏发热体11。进一步地，头部122还可以被圆滑处理，例如，可以被削尖处理，目的在于降低头部122与气溶胶形成基质之间的摩檫力，便于头部122***到气溶胶形成基质中。具体地，在本实施例中，发热体11为圆管状，头部122呈圆锥状或圆台状，头部122的下端面抵靠于发热体11的上端面上，头部122的下端外径与发热体11的外径相等。杆部121为圆柱形，杆部121的下端面可与发热体11的下端面齐平。The support rod 12 may include a rod portion 121 received in the through hole 110 and a head 122 connected to the upper end of the rod portion 121 and located outside the through hole 110. The heating component 10 is inserted into the aerosol-forming matrix via the head 122. The head 122 may have a crown structure. When the heating component 10 is inserted into the aerosol-forming substrate, the crown structure may protect the tubular heating element 11 and avoid excessive friction between the tubular heating element 11 and the aerosol-forming substrate. And damage the heating element 11. Furthermore, the head 122 can also be rounded, for example, can be sharpened, in order to reduce the friction force between the head 122 and the aerosol-forming matrix, so as to facilitate the insertion of the head 122 into the aerosol-forming matrix. Specifically, in this embodiment, the heating element 11 is in the shape of a circular tube, and the head 122 is in the shape of a cone or a truncated cone. The lower end surface of the head 122 is against the upper end surface of the heating element 11 , and the outer diameter of the lower end of the head 122 is It is equal to the outer diameter of the heating element 11 . The rod portion 121 is cylindrical, and the lower end surface of the rod portion 121 can be flush with the lower end surface of the heating element 11 .
支撑杆12可以为导电材质，也可以为绝缘材质。具体地，在本实施例中，支撑杆12采用绝缘材料，例如氧化锆陶瓷等陶瓷材料制成。第一电极14可随着杆部121延伸，与发热体11的上端导通。进一步地，杆部121还可形成有走线通道1210，该走线通道1210可用于供第一电极14走线并固定第一电极14。具体地，走线通道1210可形成于杆部121的外表面，其可由杆部121的下端面沿纵向延伸至杆部121的上端面。带有第一电极14的支撑杆12从发热体11内的通孔110穿过，可通过玻璃釉或陶瓷涂料等进行支撑杆12和发热体11之间的粘接固定，同时第一电极14与发热体11的上端通过涂覆导电浆料或钎焊实现电路导通。The support rod 12 can be made of conductive material or insulating material.
