Description

烘烤型电子烟的加热装置
技术领域
[0001] 本发明涉及电子烟技术领域, 更具体的说, 本发明涉及一种烘烤型电子烟的加 热装置。
背景技术
[0002] 通常情况下, 香烟是在明火燃烧时冒出香烟烟雾供吸烟者吸入口中的, 而香烟 明火燃烧时会分解产生烟焦油、 一氧化碳、 苯酚、 氮氧化物、 烯烃类物质、 多 环芳烃类物质等有害物质, 这些物质会严重损害人体健康。
[0003] 为避免香烟产生大量有害物质又能享受香烟的独有口味, 市场上产生了一种可 以烘烤型电子烟的加热装置, 其作用是吸烟用户吸烟时将烟草制品 (如香烟、 烟草芯) 放在其中进行电加热, 在低于烟草制品可燃烧的温度下对烟草制品进 行烘烤直至冒烟, 吸烟用户得以吸入香烟烟雾。 由于烟草制品是通过加热冒烟 而不是明火燃烧, 避免了用户吸入烟草制品因明火燃烧产生的大量有害物质, 故使用电子烟具进行吸烟得到广泛使用。
[0004] 5见有的烘烤型电子烟的加热装置, 因通常仅通过发热导体对香烟烟体的外壁进 行加热, 热传导不均匀, 导致发热导体直接与香烟外壁接触产生局部温度过高 , 容易烧焦而产生焦味, 另现有的加热管没有隔热层, 产生的高温容易传导或 辐射到电子烟的壳体及控制板而发生高温烧蚀损害。
发明概述
技术问题
[0005] 本发明的目的是提供一种烘烤型电子烟的加热装置, 该电子烟的加热装置通过 结构的改进, 使香烟烟体受热均匀, 温度均匀升温快, 不会产生焦味。
问题的解决方案
技术解决方案
[0006] 本发明的技术方案是这样实现的: 该烘烤型电子烟的加热装置, 包括用以插入 香烟并对香烟进行加热的加热管和加热管底端引出的两根电极导线, 所述加热 管的壁部包括自内而外径向分层的导热层、 发热层和隔热层, 所述发热层设有 加热电路, 所述两根电极导线与所述加热电路两端连接。
[0007] 优选地, 所述导热层由易导热耐高温的导热材料制成, 所述隔热层由不易导热 耐高温的隔热材料制成。
[0008] 优选地, 所述导热材料为导热陶瓷, 所述隔热材料为隔热陶瓷。
[0009] 优选地, 所述发热层还包括耐高温的填充材料, 所述加热电路设于所述填充材 料内。
[0010] 优选地, 所述填充材料为导热陶瓷。
[0011] 优选地, 所述加热电路为设于所述导热层外壁的涂刷电路或印刷电路。
[0012] 优选地, 所述加热电路为设于所述导热层与隔热层之间的电热丝。
[0013] 优选地, 所述加热管的内壁下部设有向内凸起用以向上支撑香烟的环形凸肩。
发明的有益效果
有益效果
[0014] 加热管设有导热层、 发热层和隔热层三层, 设有导热层可避免发热层直接与香 烟接触, 而通过导热层与香烟外壁接触则可使得发热层的发热导体的热量经过 导热层的均匀扩散后对香烟外壁均匀地加热, 可使香烟烟体内的温度均匀快速 升温, 避免发热导体与香烟直接接触造成局部加热过快容易烧焦, 避免产生的 香烟烟雾具有焦味; 又发热管设有隔热层, 可以将发热层发出的热量阻隔在隔 热层内, 起到保温作用, 使热量更多地向内传导, 发热层因此具有更好的热效 率, 同时可以避免热量向外传导或辐射到电子烟的壳体及控制板而发生高温烧 蚀或损害。
