Description

一种烤烟型电子烟发热体 技术领域
本发明创造涉及电子烟领域，特别涉及一种烤烟型电子烟的发热体。
 背景技术
电子烟又名电子香烟，主要用于戒烟和替代香烟。它有着与香烟一样的外观、与香烟近似的味道，甚至比一般香烟的口味要多出很多，也像香烟一样能吸出烟、吸出味道跟感觉来。
 技术问题
目前，烤烟型电子烟利用一个加热体对烟丝进行加热或者对一支一支的香烟进行烘烤，产生烟雾吸食，加热体是烤烟型电子烟的一个重要部件 。现有的电子烟烤烟加热体，主要为片状发热体、陶瓷管状结构发热体和FPC柔性发热体。片状发热体插入香烟的中心，用户操作不方便，并且只能适用于特制的香烟，片体厚度过厚插入香烟内较困难，片体厚度过薄容易变形甚至折断，同时片状发热体插入香烟后，发热体附近烟叶较致密，外层相对疏松，造成整根烟密度分布不均，直接与发热体接触部位的烟叶容易被烤焦，而远离发热体的烟叶往往不能得到充分的利用。陶瓷管状发热体，方便用户操作，对香烟无特制要求，然而陶瓷管状发热体受陶瓷本身特性的限制，陶瓷管的壁厚较厚，吸收热量多同时传热速率较慢，造成发热体发热速率慢，热量利用率低，FPC发热体表层为有机高分子材料，比如聚酰亚胺薄膜，其使用温度较低，同时FPC发热体为柔性结构，安装难度大。
技术解决方案
本发明创造针对目前烤烟型电子烟的发热体的上述不足，提供一种具有管状结构的电子烟发热体。
本发明创造的技术方案是一种烤烟型电子烟的发热体，包括良导热体的薄管状基体，所述的薄管状基体的内径和长度与一支香烟的外径和长度相吻合，在所述的薄管状基体的两端形成装配区，在述的薄管状基体的表面印刷电阻浆料形成发热区，在发热区的一端焊接与所述的发热区电连接的电极。
进一步的，上述的烤烟型电子烟的发热体中：所述的薄管状基体为完整管状、中间有开口的管状、一端封闭的管状、变截面的管状或双层真空管状结构中的至少一种。
进一步的，上述的烤烟型电子烟的发热体中：所述的电阻浆料为一个圆弧面均匀或非均匀印刷在薄管状基体上。
进一步的，上述的烤烟型电子烟的发热体中：所述的发热区的电阻为0.05Ω-5Ω。
 有益效果
本发明创造发热体为圆形管状结构，方便用户操作，采用金属材料为发热体基体，能够在较高的温度下使用。对金属薄壁管做绝缘处理后，在其外表面印刷电阻浆料形成发热电路，金属导热速率快，易成型能加工成壁厚较薄的薄壁管，工作时发热电路快速升温，热量传递到发热体基体上，由于其壁厚较薄吸收的热量较少，整个发热体温度快速升高，同时金属比陶瓷具有更高的导热率，能更快速地把热量传递到香烟上，在热量传递过程中损失的热量也更少，烟叶快速升温产生烟雾，给用户更好的体验。
 附图说明
图1为本发明创造实施例1发热体的结构图。
图2为本发明创造实施例1电阻浆料印刷的开关示意图。
 本发明的实施方式
本实施例是一种烤烟型电子烟的发热体，如图1和2所示，本实施例的烤烟型电子烟的发热体是一种良导热体的金属薄管状管基体，本实施例中，金属薄管状管基体内径与一支香烟的直径相当，这样，在使用时，可以方便地将香烟插入到金属薄管状管基体内，又方便金属薄管状管基体上的热量传递到香烟中。在金属薄管状管基体两端形成装配区1，对金属薄管状管体进行做绝缘处理后，在其外表面印刷电阻浆料形成发热电路形成发热区2，在发热区的一端焊接两根电极3就形成了烤烟型电子烟的发热体。在实践中，印刷电阻浆在属薄管状管基体外表面或者内表面均可，实事上，很多是印刷在属薄管状管基体外表面的，因为外表面印刷方便，另外，由于金属薄管状管基体由作为良导导热体的金属如不锈钢、铁、铜、铝、镍、钛等做成，不认内表面还是外表面印刷电阻浆料，电阻浆料发热都很快地传递到期中的香烟中。在金属薄管状管基体表面印刷电阻浆料时，根据需要可以印刷成各种设计的形状，如图2所示，就是一种非常普通的开关，通过对电阻浆料图案中线条宽度等的调节，可以将发热区的电阻设置在0.05Ω-5Ω的范围内。
针对发热速率慢，热能利用率低，客户操作困难，使用温度低。本发明创造涉及一种以金属为基体材料的发热体管状结构。本发明创造发热体为圆形管状结构，方便用户操作，采用金属材料为发热体基体，能够在较高的温度下使用。对金属薄壁管做绝缘处理后，在其外表面印刷电阻浆料形成发热电路，金属导热速率快，易成型能加工成壁厚较薄的薄壁管，工作时发热电路快速升温，热量传递到发热体基体上，由于其壁厚较薄吸收的热量较少，整个发热体温度快速升高，同时金属比陶瓷具有更高的导热率，能更快速地把热量传递到香烟上，在热量传递过程中损失的热量也更少，烟叶快速升温产生烟雾，给用户更好的体验。
本实施例是一种金属基体表面印刷电阻浆料的发热体，其基体材质包括不锈钢、铁、铜、铝、镍、钛至少一种。本实施例的金属基体管状结构发热体为完整管状、中间有开口的管状、一端封闭的管状、变截面的管状或双层真空管状结构的至少一种。本实施例的发热体结构电阻浆料为一个圆弧面均匀或非均匀印刷。本实施例的发热体结构的工作加热方式为均匀加热、分段加热，梯度加热，以及函数曲线加热至少一种，这些可以通过控制加电极的加热情况获得。本实施例的生产工艺涉及发热材料的形状，电阻浆料为流体，材质为钯银浆料、不锈钢浆料、钨浆料、钼浆料等粉体浆料，可按照需求在金属基体表面印刷不同的形状。此工艺生产的发热体的电阻值可任意调节，调节范围很广，0.05Ω-5Ω可满足不同功率的设计需求。
