Description
本发明涉及电子烟雾化器中发热装置领域，特别涉及一种采用银纳米线作为发热丝的发热体及使用这样的发热体的电子烟。The present invention relates to the field of heat generating devices in electronic cigarette atomizers, and more particularly to a heat generating body using silver nanowires as a heating wire and an electronic cigarette using such a heat generating body.
纳米线是一种纳米尺度(1纳米＝10^-9米)的线。换一种说法，纳米线可以被定义为一种具有在横向上被限制在100纳米以下(纵向没有限制)的一维结构，另外，作为宽一些的范围，横向上被限制也可以取消，只对厚度进行限制，厚度在纳米级的也可以称为纳米线。这种尺度上，量子力学效应很重要,因此也被称作"量子线"。根据组成材料的不同，纳米线可分为不同的类型，包括金属纳米线(如:Ni，Pt，Au等)，半导体纳米线(如:InP，Si，GaN等)和绝缘体纳米线(如:SiO2，TiO2等)。分子纳米线由重复的分子元组成，可以是有机的(如:DNA)或者是无机的(如:Mo6S9-xIx)。作为纳米技术的一个重要组成部分，纳米线可以被用来制作超小电路。银纳米线除具有银优良的导电性之外，由于纳米级别的尺寸效应，还具有优异的透光性、耐曲挠性。因此被视为是最有可能替代传统ITO透明电极的材料，为实现柔性、可弯折LED显示、触摸屏等提供了可能，并已有大量的研究将其应用于薄膜太阳能电池。此外由于银纳米线的大长径比效应，使其在导电胶、导热胶等方面的应用中也具有突出的优势。Nanowires are a nanoscale (1 nm = 10^-9 m) line. In other words, a nanowire can be defined as a one-dimensional structure having a lateral limitation of 100 nm or less (with no limitation in the longitudinal direction). In addition, as a wider range, the lateral limitation can also be canceled, only Limiting the thickness, the thickness of the nanoscale can also be called nanowires. At this scale, quantum mechanical effects are important and are therefore also referred to as "quantum wires." Depending on the composition of the materials, nanowires can be divided into different types, including metal nanowires (such as Ni, Pt, Au, etc.), semiconductor nanowires (such as: InP, Si, GaN, etc.) and insulator nanowires (such as: SiO2, TiO2, etc.). Molecular nanowires are composed of repeating molecular elements, which can be organic (eg, DNA) or inorganic (eg, Mo6S9-xIx). As an important part of nanotechnology, nanowires can be used to make ultra-small circuits. In addition to the excellent electrical conductivity of silver, silver nanowires have excellent light transmission and flexural resistance due to the size effect of the nanometer scale. Therefore, it is considered to be the most likely material to replace the traditional ITO transparent electrode, which provides a possibility for flexible, bendable LED display, touch screen, etc., and has been extensively studied for its application to thin film solar cells. In addition, due to the large aspect ratio effect of silver nanowires, it also has outstanding advantages in the application of conductive adhesives and thermal conductive adhesives.
这些银纳米线在上述的应用中，一般只做为导线使用，如在一款发热器中，采用碳纤维发热丝发热，而采用银纳米线做电源导线，这种发热器由于采用银纳米线做导线是透明的，因此，应用非常广阔。但目前，还没有直接采用银纳米线做电阻丝，加电后银纳米线(膜)本身发热的应用。In the above applications, these silver nanowires are generally only used as wires. For example, in a heater, carbon fiber heating wire is used for heating, and silver nanowires are used as power wires. The heater is made of silver nanowires. The wires are transparent, so the application is very broad. However, at present, there is no direct use of silver nanowires as resistance wires, and the application of the silver nanowires (films) themselves after heating.
另外，现有的电子烟根据加热物质的形态可分为两类。一类是加热固体的电子烟，该类电子烟用来加热烟草、烟膏等物质。另一类是加热流体的电子烟，该类电子烟主要用来加热烟油。这两大类电子烟都有类似的部件，即加热体。加热体由基体材料和发热材料组成，基体材料有无纺布、棉、陶瓷等，发热材料有金属丝、电阻浆料等。基体材料和发热材料的组合方式有多种：第一种，弹簧状金属丝中间穿棉、弹簧状金属丝外周裹上无纺布、弹簧状金属丝烧结在多孔陶瓷外表面、弹簧状金属丝烧结在多孔陶瓷管内表面等，这种组合方式主要用来加热烟油。第二种，电阻浆料印刷在致密陶瓷表面、电阻浆料印刷在致密陶瓷内部，这种组合方式可以用来加热固体，也可和棉或无纺布配合用来加热流体。第三种，电阻浆料 印刷在片状高分子材料表面，这种组合方式主要用来加热固体。以上所述几种基体材料和发热材料组合方式，都有很大的产品缺陷和使用问题。其中，金属丝和无纺布或棉的组合，使用时温度过高会烧糊无纺布或棉，影响被加热物体的口感和使用者的健康。其中，金属丝和陶瓷的组合，在生产过程中金属丝极易被氧化，导致其强度变低。其中，电阻浆料和陶瓷的组合，在使用时发热速度很慢，热量利用效率低下。其中，电阻浆料和高分子材料的组合，在使用时产生高温，导致高分子材料变色变形等问题。In addition, the existing electronic cigarettes can be classified into two types according to the form of the heating substance. One type is an electronic cigarette that heats solids, which is used to heat tobacco, smoke, and the like. The other type is an electronic cigarette that heats a fluid, which is mainly used to heat smoke oil. Both types of electronic cigarettes have similar components, namely heating bodies. The heating body is composed of a base material and a heat generating material, and the base material includes a non-woven fabric, cotton, ceramics, etc., and the heating material includes a metal wire, a resistive paste, and the like. There are various combinations of the base material and the heat-generating material: the first type, the spring-like wire is worn in the middle, the spring-like wire is wrapped around the outer circumference, the spring-like wire is sintered on the outer surface of the porous ceramic, and the spring-like wire is Sintered on the inner surface of a porous ceramic tube, etc., this combination is mainly used to heat the smoke oil. Second, the resistive paste is printed on the dense ceramic surface and the resistive paste is printed inside the dense ceramic. This combination can be used to heat the solid or in combination with cotton or non-woven fabric to heat the fluid. Third, the resistive paste is printed on the surface of the sheet-like polymer material, and this combination is mainly used to heat the solid. The combination of several kinds of matrix materials and heat-generating materials mentioned above has great product defects and use problems. Among them, the combination of the wire and the non-woven fabric or cotton, when used at a high temperature, burns the non-woven fabric or cotton, affecting the taste of the heated object and the health of the user. Among them, the combination of wire and ceramic, the wire is easily oxidized during the production process, resulting in its strength becoming lower. Among them, the combination of the resistor paste and the ceramic has a low heat generation rate and a low heat utilization efficiency. Among them, the combination of the resistive paste and the polymer material causes a high temperature during use, which causes problems such as discoloration of the polymer material.
