Description

一种扁平发热丝的雾化芯 技术领域
本发明涉及电子烟技术领域，具体的说，是一种扁平发热丝的雾化芯。
背景技术
吸烟、被动吸烟会导致各种疾病，易患咽喉炎、气管炎、肺炎、肺气肿、哮喘及肺癌等恶性病变。因此戒烟百利而无一害，但是戒烟对于烟民来说是十分困难的事，所以有电子产品公司就模拟香烟发明了电子烟，来帮助烟民戒烟。电子烟是由中国人发明及生产，2004年由北京中医师韩力取得发明专利，于2005年正式面向中国市场。在韩力发明电子烟前，美国人HerbertA.Gilbert在1963年曾取得一款“无烟、非烟草香烟”的专利设计，该装置把液态尼古丁加热，产生蒸气，模仿吸烟感觉。最初电子烟是应国外的要求，因为国外有很多法律法规禁止在公共场所吸烟，而且国外人的生活水准普遍较高，对生活质量要求严格。所以，最初就是设计用来外贸出口的。主要销售途径在国外欧美市场。
电子烟一般由烟嘴、端盖、油舱、雾化芯、底座和电池仓组成，雾化芯通过油道与油舱连通，通过烟道排出烟雾。现有技术中，电子烟的雾化芯的发热丝是沿一轴线方向螺旋延伸的发热丝，发热丝外面包导油棉或内部装导油棉，安装麻烦，之后再将发热丝装到支架上，因不同的人操作不同，所装的棉松紧度也不同误差大、成本高，容易产生异味或口感差的问题；在支架尺寸一定的时候，导油棉本身的误差会导至发热丝与导油棉之间产生过紧或过松的配合关系，容易导至漏油或导油不畅而引起糊芯。
现发明一种扁平发热丝的雾化芯，已解决上述问题。
发明内容
本发明的目的在于设计出一种扁平发热丝的雾化芯，具有结构简单，安装方便，烟雾量大，口感稳定，使用成本低的优点。
本发明通过下述技术方案实现：一种扁平发热丝的雾化芯，包括具有油道的雾化芯壳体，雾化芯壳体内部具有与外部连通的内腔，该内腔内依次设置有导油棉、发热丝和电极；所述发热丝为围绕一中心盘绕的扁平盘状的发热丝，所述导油棉的一端面与发热丝的一侧盘面贴合连接，所述导油棉与发热丝相贴合的一端面的形状与发热丝的盘面形状匹配，所述导油棉的另一端面与油道的端口贴合连接；所述电极位于发热丝的另一侧盘面并与发热丝连接。进一步的，所述导油棉与雾化芯壳体内腔形状匹配。雾化芯壳体通过油道与油舱连通，油舱内的烟油通过油道与导油棉接触连接，烟油通过虹吸作用被吸入到导油棉内部储存；扁平盘状的发热丝与端面截面为盘状的导油棉相互贴合，增大了接触面积，使得加热丝加热导油棉时能够产生更多的烟雾；同时扁平状的发热丝的结构更加的规整和扁平，能够轻松的通过雾化芯壳体的内壁进行定位，方便装配，并且在装配或更换导油棉时，不必再在发热丝上进行缠绕、包裹或插接等固定，简化了安装流程和难度，使得导油棉的装配精度要求得到降低，能够有效避免装配精度的误差而导致的漏油、糊芯、烟雾小、口感差等问题，同时也降低了使用的成本。进一步的，所述扁平盘状的发热丝可通过一根电阻丝盘绕而成，或者通过对原料进行切割或蚀刻的方式去除多余材料而制成。
进一步的为更好的实现本发明，特别采用下述设置结构：所述雾化芯壳体包括相互连接的雾化芯外罩和雾化芯固定圈；所述雾化芯外罩上开设有烟道，所述电极上开设有与烟道连通的进气通孔；所述油道开设在雾化芯外罩上；所述雾化芯固定圈套接在雾化芯外罩上并形成所述内腔。雾化芯固定圈与发热丝的另一侧盘面相抵并将发热丝、电极和导油棉压在雾化芯外罩内部。雾化芯固定圈通过卡接的连接形式套接在雾化芯外罩上，能够更加方便的对雾化芯外罩中的加热丝或导油棉进行更换，节约了拆装时间，降低了使用成本。吸入雾化芯中的空气先通过电极的进气通孔再通过烟道以进入吸烟者的口部。更进一步的，所述雾化芯固定圈与雾化芯外罩的配合处设置有密封圈，以防止跑烟、漏油的情况发生。更进一步的，为了能够使烟雾具有更好的导流性能，所述导油棉上开设有与烟道连通的通孔。
进一步的为更好的实现本发明，特别采用下述设置结构：还包括设置在雾化芯外罩内的支架，所述支架的中部具有能够容纳电极的电极通孔，所述支架的一端面与发热丝的另一侧盘面相抵，所述电极穿过所述通孔而与发热丝连接，所述雾化芯固定圈与支架的另一端面相抵并将支架、电极、发热丝和导油棉压在雾化芯外罩内部。电极穿设在支架的电极通孔内，能够充分利用有限的空间，使雾化芯的体积更加的小巧紧凑，提高了结构的稳定性。吸入雾化芯中的空气先通过电极的进气通孔再通过烟道以进入吸烟者的口部；支架对空气起到导流的作用，气流通过支架被引导到电极处，再通过电极的进气通孔流向烟道，同时支架能够对雾化芯壳体起到支撑的作用；支架也能够对发热丝起到隔热的作用。
进一步的为更好的实现本发明，特别采用下述设置结构：所述支架与发热丝相抵的一端面上设置有肋条，所述肋条与发热丝相抵使发热丝与支架之间形成能够通过气流的间隙。该间隙能够通过气流，能够形成一空气隔层，进一步的阻碍了发热丝的热量传递，起到隔热的作用。
进一步的为更好的实现本发明，特别采用下述设置结构：所述支架的材料为陶瓷。因支架本身的材料属性，能够对发热丝产生的热量起到隔热的作用，同时对穿设在通孔中的电极起到绝缘的作用，防止电极与雾化芯外壳直接接触而使用者触电的情况发生。
进一步的为更好的实现本发明，特别采用下述设置结构：所述扁平盘状的发热丝按照阿基米德螺旋线的的轨迹盘绕而成。根据阿基米德螺旋线的轨迹盘绕使得该发热丝的结构更加的紧凑合理。
进一步的为更好的实现本发明，特别采用下述设置结构：所述发热丝的横截面的形状为圆形或矩形。实际的截面形状应根据使用情况和要求来决定。
进一步的为更好的实现本发明，特别采用下述设置结构：所述发热丝在其长度方向上呈连续S型延伸。连续S型的延伸方式使得一定端面面积下的扁平盘状发热丝的长度得到增加，提高了发热量，能够更快更多的加热导油棉上的烟油，提供更加快速的出烟速度和更浓厚的烟雾，提高吸烟者的口感。
进一步的为更好的实现本发明，特别采用下述设置结构：所述发热丝在其长度方向上呈螺旋状延伸。螺旋状的延伸方式使得一定端面面积下的扁平盘状发热丝的长度得到增加，提高了发热量，能够更快更多的加热导油棉上的烟油，提供更加快速的出烟速度和更浓厚的烟雾，提高吸烟者的口感。
进一步的为更好的实现本发明，特别采用下述设置结构：所述发热丝的材料为铁铬合金。

安装时，先将雾化芯外罩5水平放置在平面上，然后将导油棉1装入雾化芯外罩5的内腔内部，并使导油棉1的底部与油道8贴合，同时使导油棉1的通孔与烟道8对接以保持连通状态，之后将发热丝2的底面贴合在导油棉1的顶部，再将电极3穿过支架4的电极通孔并与发热丝2的顶面的线脚连接，然后将支架4的肋条抵在发热丝2的顶面上，最后将雾化芯固定圈6卡在雾化芯外罩5的顶部以将电极3、支架4、发热丝2和导油棉1紧紧的压在雾化芯外罩5内，使它们彼此紧密的接触，防止松动；此时组成一扁平发热丝的雾化芯。雾化芯的烟道8与导油棉1的通孔和电极3的进气通孔形成一完整的气流通道，气体和烟雾能够通过烟道8排出雾化芯。
将雾化芯的雾化芯外罩5的烟道8通过螺纹与油舱7连接，烟道8与集成在油舱7内的通道连通以对烟雾进行导流，油道9与油舱7连通，其中，雾化芯外罩5的外壁与油舱7通过密封圈进行密封。之后再连接上上盖、底座和电池仓便可以进行使用。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
