Description

发热组件及气溶胶形成装置Heating component and aerosol forming device 【技术领域】【Technical field】
本发明涉及加热不燃烧发烟设备技术领域，尤其涉及一种发热组件及气溶胶形成装置。The invention relates to the technical field of heat-not-burn smoking equipment, in particular to a heating component and an aerosol forming device.
【背景技术】【Background technique】
电子烟作为香烟替代品，因其具有使用安全、方便、健康、环保等优点，而越来越受到人们的关注和青睐；比如，加热不燃烧电子烟，亦称为加热不燃烧气溶胶形成装置。As a substitute for cigarettes, electronic cigarettes have attracted more and more attention and favor because of their advantages of safety, convenience, health, and environmental protection; for example, heat-not-burn electronic cigarettes, also known as heat-not-burn aerosol-forming devices .
现有的加热不燃烧气溶胶形成装置，其加热方式通常为管式***加热或中心嵌入加热；管式***加热是指加热管围绕于气溶胶形成基质(例如烟草)外以对气溶胶形成基质进行加热，中心嵌入加热是将加热组件***气溶胶形成基质内以对气溶胶形成基质进行加热。其中，加热组件因其制造简单、使用方便等特点而被广泛应用；目前的发热组件主要采用陶瓷或经绝缘处理的金属作基底，然后在基底上印刷或镀膜电阻发热线路，并经高温处理后使电阻发热线路固定在基底上而形成。Existing heat-not-burn aerosol-forming devices are usually heated by tubular peripheral heating or central embedded heating; tubular peripheral heating means that the heating tube surrounds the aerosol-forming substrate (such as tobacco) to heat the aerosol-forming substrate. For heating, center-embedded heating is to insert a heating element into the aerosol-forming substrate to heat the aerosol-forming substrate. Among them, heating components are widely used because of their simple manufacture and convenient use. At present, heating components mainly use ceramic or insulating treated metal as the substrate, and then print or coat the resistance heating circuit on the substrate, and after high temperature treatment It is formed by fixing the resistance heating circuit on the base.

由于现有发热组件上的电阻发热线路是后期印刷或镀膜在基底上的一层薄膜，在多次将发热组件***气溶胶形成基质的使用过程中，因基底的弯曲形变，该电阻发热线路经过高温发热时，容易从基底上脱落，稳定性差，且在发热过程中，由于电阻发热线路仅与基底设置有电阻发热线路的一面的气溶胶形成基质接触而不与基底背面的气溶胶形成基质接触，从而导致对气溶胶形成基质的加热均匀性较差。Since the resistance heating circuit on the existing heating element is a layer of film that is later printed or coated on the substrate, in the process of inserting the heating element into the aerosol-forming substrate for many times, the resistance heating circuit passes through the substrate due to the bending and deformation of the substrate. When heating at high temperature, it is easy to fall off the substrate, and the stability is poor, and during the heating process, because the resistance heating circuit only contacts the aerosol-forming substrate on the side of the substrate where the resistance heating circuit is arranged, and does not contact the aerosol-forming substrate on the back of the substrate. , resulting in poor heating uniformity of the aerosol-forming substrate.
本申请提供一种发热组件及气溶胶形成装置，该发热组件能够解决现有发热组件上的电阻发热线路经过高温发热时，容易从基底上脱落，稳定性较差，且在发热过程中，电阻发热线路对气溶胶形成基质的加热均匀性 较差的问题。The present application provides a heating component and an aerosol forming device.

具体的，发热组件90包括发热体91、第一电极92a和第二电极92b。Specifically, the heating component 90 includes a heating body 91, a first electrode 92a and a second electrode 92b.
其中，发热体91用于***并加热气溶胶形成基质98；该发热体91相比于现有丝印或镀膜在基底上而形成的电阻发热线路，能够直接、独立地***气溶胶形成基质98，且不会出现经过高温发热时发热体91从基底上脱落而导致失效的问题，大大提高了发热组件90的稳定性；具体的，该发热体91具有第一连接端E和与第一连接端E相对的第二连接端F，当发热体91***烟草的过程中，发热体91的第二连接端F先***烟草，因此，为方便发热体91***烟草内，发热体91的第二连接端F具体可设置为尖端，即，呈三角形结构，以形成尖端部D；且尖端的相邻两条边所形成的夹角具体可呈45度至90度，例如60度。可以理解的是，本申请中的第一连接端E和第二连接端F分别包括位于相应一端所占的一定面积区域，而非指端点或端面。具体的，第一电极92a和第二电极92b具体设置在(即位于)发热体91的第一连接端E，且第一电极92a与发热体91的第一连接端E电连接，第二电极92b与发热体91的第一连接端E绝缘设置，以避免发生短路；且第二电极92b从发热体91的第一连接端E延伸至第二连接端F并与第二连接端F电连接，从而使发热体91的第一连接端E与第二连接端F之间形成电流回路。这样不仅加工工艺更为简单，且有效提高了发热组件90的整体强度，同时减少了使用过程中对烟草的粘附以及对雾化后的烟油的粘附。Among them, the heating element 91 is used to insert and heat the aerosol forming matrix 98; the heating element 91 can be directly and independently inserted into the aerosol forming matrix 98 compared with the existing resistance heating circuit formed by silk screen printing or coating on the substrate, And there is no problem that the heating body 91 falls off from the base and causes failure when heating at a high temperature, which greatly improves the stability of the heating assembly 90; specifically, the heating body 91 has a first connection end E and a first connection end The second connection end F opposite to E, when the heating element 91 is inserted into the tobacco, the second connection end F of the heating element 91 is inserted into the tobacco first. Therefore, in order to facilitate the insertion of the heating element 91 into the tobacco, the second connection of the heating element 91 The end F can be specifically set as a pointed end, that is, in a triangular structure to form a pointed end portion D; and the included angle formed by two adjacent sides of the pointed end can be 45 degrees to 90 degrees, for example, 60 degrees. It can be understood that the first connection end E and the second connection end F in this application respectively include a certain area occupied by the corresponding end, rather than refer to an end point or an end surface. Specifically, the first electrode 92a and the second electrode 92b are specifically arranged at (ie located at) the first connection end E of the heating body 91, and the first electrode 92a is electrically connected to the first connection end E of the heating body 91, and the second electrode 92b is insulated from the first connection end E of the heating body 91 to avoid short circuit; and the second electrode 92b extends from the first connection end E of the heating body 91 to the second connection end F and is electrically connected to the second connection end F , so that a current loop is formed between the first connection end E and the second connection end F of the heating element 91 . In this way, not only the processing technology is simpler, but also the overall strength of the heating element 90 is effectively improved, and the adhesion to the tobacco and the atomized e-liquid during use is reduced at the same time.
具体的，发热体91的形状和尺寸不限，可以根据需要设计。在一个具 体实施例中，发热体91为条形，如长方形且长方形的一端形成尖端。Specifically, the shape and size of the heating body 91 are not limited, and can be designed as required. In a specific embodiment, the heating element 91 is in the shape of a bar, such as a rectangle, and one end of the rectangle forms a tip.
具体的，参见图1a，发热体91包括第一发热区A和与第一发热区A连接的第二发热区B，其中，第一发热区A为***气溶胶形成基质98进行加热的主要雾化区域，其上的雾化温度集中在280℃到350℃，占雾化区域面积的75％以上，第二发热区B是发热体91的主要配合段，温度在150℃以下。具体的，发热体91的第一发热区A的发热温度与第二发热区B的发热温度的比值可大于2；在具体实施例中，第一电极92a具体设置在发热体91的第二发热区B，以降低位于第二发热区B的陶瓷发热体91的雾化温度；可以理解的是，发热体91的第一连接端E位于发热体91的第二发热区B所在的位置，第二连接端F位于发热体91的第一发热区A所在的位置。Specifically, referring to FIG. 1a, the heating body 91 includes a first heating area A and a second heating area B connected to the first heating area A, wherein the first heating area A is the main mist inserted into the aerosol forming matrix 98 for heating The atomization temperature is concentrated at 280°C to 350°C, accounting for more than 75% of the area of the atomization area. The second heating area B is the main matching section of the heating element 91, and the temperature is below 150°C. Specifically, the ratio of the heating temperature of the first heating area A to the heating temperature of the second heating area B of the heating body 91 may be greater than 2; zone B to reduce the atomization temperature of the ceramic heating element 91 located in the second heating zone B; it is understandable that the first connection end E of the heating element 91 is located where the second heating zone B of the heating The two connecting ends F are located where the first heating area A of the heating element 91 is located.
