电子香烟的发热组件和雾化结构
技术领域
本发明涉及一种电子香烟的发热组件。
本发明还涉及一种电子香烟的雾化结构。
背景技术
随着人们对传统香烟危害的认知， 电子香烟已经逐渐普及， 现有的电子香 烟大多与传统点燃式的香烟外观接近、 味道相似， 能像传统香烟一样吸出、 吐 出烟雾， 能够减轻人们对尼古丁等有害物质的依赖， 从而达到戒掉烟瘾的目的。
电子香烟主要由烟杆 1、 雾化器 2和烟嘴 3组成，且其内部存在有由上述烟 杆 1、 雾化器 2和烟嘴 3界定的用于存储烟液的储液腔 123 , 可参见图 1。 例如， 中国专利申请 CN201220223286. 6， 雾化器 2主要包括外形大致呈圓柱体的中空 雾化杆 21、 纤维绳 22和发热丝 23等， 其中， 纤维绳 22和发热丝 23组成电子 香烟的发热组件， 纤维绳的两个端部放置在上述储液腔 123内， 其中间部位则 横向穿过中空雾化杆 21而容纳在中空雾化杆 21的内部， 发热丝 23缠绕在纤维 绳 22容纳在中空雾化杆 21内的部分（即中间部位）上。 当将烟液注入储液腔 123内时， 烟液自动吸附在纤维绳 22内， 发热丝 23在接通电路后产生高温， 将 吸附在纤维绳 22上的烟液雾化。 现有的电子香烟结构均釆用纤维绳来作为烟液 从储液腔至中空雾化杆的导液载体和发热丝的支撑载体， 以实现烟液的雾化， 然而， 在发热丝长期处于高温的情况下， 纤维绳容易产生烧焦味， 严重影响电 子香烟的口感，甚至出现纤维绳烧焦而损坏的情况，影响纤维绳的导液可靠性 ； 从外观上看， 纤维绳存在不美观、 容易积灰、 不清洁等问题， 且由于纤维绳的 柔性材质，通常还需要在中空雾化杆的上端部外面套设密封套 24以固定纤维绳; 另外， 发热丝在纤维绳上的缠绕方式较为单一， 不能更好地对导液载体上烟液 与加热丝之间的位置关系进行合理布局， 导致原材料的浪费和雾化效率的降低。

空心雾化杆 200容置在电子香烟的储液腔中， 具体地， 空心雾化杆 200为 构成储液腔的其中一部分边界， 以确保空心雾化杆 200与储液腔中的烟液直接 接触， 而且对于本领域技术人员来说， 本发明可以釆用多种储液腔的构成手段。
发热组件 300横向穿设在该空心雾化杆 200上， 其包括导液陶瓷棒 500和 发热丝 700。导液陶瓷棒 500的两个端部放置在上述储液腔内， 其中间部位横向 穿过该空心雾化杆 200而容纳在该空心雾化杆 200的内部， 而发热丝 700设置 在导液陶瓷棒 500的上述中间部位。 本发明釆用导液陶瓷棒 500替代现有的纤 维绳来作为烟液从储液腔至中空雾化杆的导液载体和发热丝的支撑载体， 当其 作为导液载体， 可以借助导液陶瓷棒自身多孔结构使储液腔中的烟液自动吸附 在其上， 且导液均勾持久， 能有效保证电子香烟的导液可靠性； 当其作为发热 丝的支撑载体时， 可以借助其耐高温的特性， 在发热丝长期处于高温的情况下 也无烧焦味， 从而使得产生的气流更切合电子香烟的要求， 口感更接近真正的 香烟； 而且， 导液陶瓷棒不易损坏， 外形美观清洁， 不容易积灰； 进一步地， 由于导液陶瓷棒的硬质材料特性可简化电子香烟雾化器的结构， 不必像现有纤 维绳方案中需要在中空雾化杆的上端部外面套设密封套以固定纤维绳， 而且导 液陶瓷棒的硬质材料特性可实现发热丝在导液陶瓷棒上的多种布局， 从而使导 液载体上烟液与加热丝之间的位置关系分布得更合理， 以提高热利用率， 使雾 化效果明显改善， 并节约了原材料。

如图 4a所示，为本发明电子香烟的发热组件 300的第三个实施例的立体图， 在该实施例中， 发热丝 700b以螺旋状嵌装在导液陶瓷棒 500的内部， 以提高发 热丝的热利用率， 提高雾化效果。 如图 4b所示， 为本发明电子香烟的发热组件 的第四个实施例的立体图，其与第三个实施例的不同点仅在于， 在导液陶瓷棒
500的中部设有沿该导液陶瓷棒 500轴向延伸的通孔 510 , 该通孔 510可促进导 液陶瓷棒的导液效果， 且确保发热丝与烟液有更充分的接触， 使雾化效果明显 改善， 并节约了原材料。
在其他一些实施例中， 导液陶瓷棒 500上设有多个穿孔， 发热丝依次穿过 上述穿孔并缠绕在导液陶瓷棒 500上。 本发明的穿孔设计可使发热丝从导液陶 瓷棒 500的内部穿过， 确保载有烟液的导液陶瓷棒 500与发热丝之间穿插交错 分布， 以提高发热丝的热利用率， 提高雾化效果， 并实现导液载体上烟液与加 热丝之间的位置关系最优布局。 如图 5a至图 6b所示， 穿孔设置为沿导液陶瓷棒 500的径向延伸且上述多 个穿孔沿导液陶瓷棒 500的轴向排列。
图 5a和图 5b为本发明电子香烟的发热组件的第五个实施例的立体图， 发 热丝 700c包括若干个依次连接的发热丝小单元， 该发热丝单元包括依次连接的 第一直线部、 容纳在穿孔内的第二直线部和第三直线部， 上述第一直线部缠绕 在导液陶瓷棒的外表面且其自第二直线部所在穿孔的顶部延伸至前一相邻穿孔 的顶部； 上述第三直线部缠绕在导液陶瓷棒的外表面且其自第二直线部所在穿 孔的底部延伸至后一相邻穿孔的底部。 在本实施例中， 也可以在导液陶瓷棒 500 的中部设有沿该导液陶瓷棒 500轴向延伸的通孔 510,该通孔 510可促进导液陶 瓷棒的导液效果， 且确保发热丝与烟液有更充分的接触， 使雾化效果明显改善， 并节约了原材料。
图 6a和图 6b为本发明电子香烟的发热组件 300的第六个实施例的立体图， 其与第五个实施例的不同点仅在于发热丝 700的缠绕方式不同， 且该第六个实 施例为本发明发热组件 300的最优实施例。 在本实施例中， 发热丝 700d包括若 干个依次连接的发热丝小单元， 该发热丝小单元包括依次连接的第一弧形段 710、容纳在穿孔内的第二直线段 720以及第三弧形段 730,上述第一弧形段 710 缠绕在导液陶瓷棒的外表面且其自第二直线段 720所在穿孔的顶部延伸至前一 相邻穿孔的底部， 上述第三弧形段 730缠绕在导液陶瓷棒 500的外表面且其自 第二直线段 720所在穿孔的底部延伸至后一相邻穿孔的顶部； 所述第一弧形段 710和第三弧形段 730分别位于过第二直线段 720所在穿孔中心轴线的导液陶瓷 棒 500的轴线截面的两侧。 如图 6c所示， 为图 6a中电子香烟的发热组件的发 热丝的立体图， 发热丝釆用这种交错穿插的缠绕方式可以实现导液载体上烟液 与加热丝之间的位置关系较优布局， 确保发热丝与烟液有更充分的接触，空间利 用率、 热利用率和雾化效果均处于较佳状态。 在本实施例中， 也可以在导液陶 瓷棒 500的中部设有沿该导液陶瓷棒 500轴向延伸的通孔 510,该通孔 510可促 进导液陶瓷棒的导液效果， 且确保发热丝与烟液有更充分的接触， 使雾化效果 明显改善， 并节约了原材料。
需要说明的是， 在本发明对于发热丝的数量、 穿孔的排列以及是否设置通 孔均不设限制。 如图 7a和 7b为本发明电子香烟的发热组件的第七个实施例的 立体图， 在本实施例中， 穿孔沿导液陶瓷棒 500的径向延伸， 上述多个穿孔在 导液陶瓷棒 500排列形成第一列穿孔组合和第二列穿孔组， 且第一列穿孔组和 第二列穿孔组均沿导液陶瓷棒的轴向排列； 发热丝 700e包括第一发热丝 701和 第二发热丝 702 ,该第一发热丝 701穿过上述第一列穿孔组并缠绕在导液陶瓷棒 500上， 该第二发热丝 702穿过上述第二列穿孔组并缠绕在导液陶瓷棒 500上。
另外， 在本发明的技术方案中， 还可在导液陶瓷棒 500接触烟液的部位设 置多个向导液陶瓷棒 500内部延伸的孔， 上述孔可以是通孔也可以是盲孔， 从 而促进导液陶瓷棒 500方便快捷地吸附烟液。
