Description

发热组件及气溶胶形成装置 【技术领域】
本发明涉及加热不燃烧发烟设备技术领域，尤其涉及一种发热组件及气溶胶形成装置。
【背景技术】
电子烟作为香烟替代品，因其具有使用安全、方便、健康、环保等优点，而越来越受到人们的关注和青睐；比如，加热不燃烧电子烟，亦称为加热不燃烧气溶胶形成装置。
现有的加热不燃烧气溶胶形成装置，其加热方式通常为管式外围加热或中心嵌入加热；管式外围加热是指加热管围绕于气溶胶形成基质(例如烟草)外以对气溶胶形成基质进行加热，中心嵌入加热是将加热管插入气溶胶形成基质内以对气溶胶形成基质进行加热。其中，加热组件因其制造简单、使用方便等特点而被广泛应用。目前的发热组件主要采用陶瓷或经绝缘处理的金属作基底，然后在基底上印刷或镀膜电阻发热线路，并经高温处理后使电阻发热线路固定在基底上而形成。
然而，由于现有发热组件上的电阻发热线路是后期印刷或镀膜在基底上的一层薄膜，在多次将发热组件插入气溶胶形成基质的使用过程中，因基板的弯曲形，该电阻发热线路经过高温发热时容易从基底上脱落，稳定性差，且在发热过程中，由于电阻发热线路仅与基底设置有电阻发热线路的一面的气溶胶形成基质接触而不与基底背面的气溶胶形成基质接触，从而导致对气溶胶形成基质的加热均匀性较差。
【发明内容】
本申请提供一种发热组件及气溶胶形成装置，该发热组件能够解决现有发热组件上的电阻发热线路经过高温发热时，容易从基底上脱落，稳定性差，且在发热过程中，电阻发热线路对气溶胶形成基质的加热均匀性较差的问题。
为解决上述技术问题，本申请采用的一个技术方案是：提供一种发热组件，该发热组件包括发热体，发热体用于插入并加热气溶胶形成基质，且发热体包括间隔设置的第一延伸部和与第一延伸部的一端相连的第二延伸部，第一延伸部及第二延伸部均用于至少部分插入气溶胶形成基质并在通电时产生热量以加热气溶胶形成基质。
为解决上述技术问题，本申请采用的另一个技术方案是：提供一种气溶胶形成装置，该气溶胶形成装置包括壳体和设置在壳体内的发热组件和电源组件；其中，电源组件与发热组件连接，用于向发热组件供电，发热组件为上述所涉及的发热组件。
本申请提供的发热组件及气溶胶形成装置，该发热组件包括用于插入并加热气溶胶形成基质的发热体，该发热体包括间隔设置的第一延伸部和与第一延伸部的一端相连的第二延伸部，且第一延伸部及第二延伸部均用于至少部分插入气溶胶形成基质并在通电时产生热量以加热气溶胶形成基质，相比于现有丝印在陶瓷基底上的发热体，本申请的发热体能够直接、独立地插入气溶胶形成基质，且不会出现经过高温发热时从陶瓷基底上脱落而导致失效的问题，大大提高了发热组件的稳定性；且由于该发热体直接插入并加热气溶胶形成基质，大大提高了对气溶胶形成基质的加热均匀性。

可以理解的是，上述采用陶瓷整片发热体11，能够减少最高温度热点面积，消除了疲劳开裂和疲劳电阻增大的风险，具有较好的一致性；且由于该陶瓷发热材料的高强度及微晶结构所带来的光滑度，该发热体11表面较易清洁、不易粘附；另外，采用陶瓷生产工艺制作陶瓷发热体11，陶瓷生产工艺主要包括原料混合、成型及烧结、切割工序，工艺较为简单且方便控制，成本较低，有利于生产化的推广和经济效益的提高。
具体的，该导电陶瓷发热体11具体包括主要成分及晶体成分；其中，主要成分用于导电并使导电陶瓷的发热体11形成一定的电阻；主要成分具体可为锰、锶、镧、锡、锑、锌、铋、硅、钛中的一种或多种；所述晶体成分，即，陶瓷材料的主料，晶体成分具体可为锰酸镧、锰酸锶镧、氧化锡、氧化锌、氧化锑、氧化铋、氧化硅、氧化钇中的一种或多种。在其他实施方式中，发热体11也可以是金属合金制成或者铁硅合金或铁硅铝合金制成的陶瓷合金。
具体的，参见图1a，在一实施例中，该发热组件10具体包括第一延伸部111和与第一延伸部111连接的第二延伸部112，且在具体实施例中，第一延伸部111和第二延伸部112均用于至少部分插入气溶胶形成基质102并在通电时产生热量以加热气溶胶形成基质102；可以理解的是，该第一延伸部111和第二延伸部112可独立、直接地插入气溶胶形成基质102，而现有的丝印或镀膜在陶瓷基板上的发热体其需要借助陶瓷基板才可插入气溶胶形成基质102，其本身是无法直接插入气溶胶形成装置，且本申请提供的第一延伸部111和第二延伸部112不会出现经过高温发热时从陶瓷基底上脱落而导致失效的问题，大大提高了发热组件10的稳定性。
具体的，第一延伸部111及第二延伸部112用于插入气溶胶形成基质102的部分的相背的两个表面均与气溶胶形成基质102接触；可以理解的是，由于本申请的发热体11是直接插入气溶胶形成基质102，其无需借助基板，因此， 该发热体11的第一延伸部111和第二延伸部112的至少两个相对的表面均可直接与气溶胶形成基质102接触，从而大大提高热量的利用率及加热效率。
在另一实施例中，参见图1b和图3a，该发热组件10还包括用于完全插入并加热气溶胶形成基质102的第三延伸部113；具体的，在该实施例中，第一延伸部111和第二延伸部112并列间隔设置，且第一延伸部111和第二延伸部112相靠近的一端通过该第三延伸部113连接；其中，第一延伸部111和第二延伸部112相靠近的一端具体是指先与气溶胶形成基质102接触并插入的端部；可以理解的是，第一延伸部111、第二延伸部112和第三延伸部113形成为一大致为U型的结构；且在具体实施例中，第一延伸部111、第二延伸部112和第三延伸部113为导电陶瓷一体成型并烧结；具体的，可通过激光切割的方式切割发热体基板以形成切槽114，从而得到具有第一延伸部111和第二延伸部112以及第三延伸部113的发热体11。可以理解，发热体11也可以直接烧结成型。
具体的，第一延伸部111和第二延伸部112以及第三延伸部113的形状不限，可以根据实际需要设计。具体的，第一延伸部111和第二延伸部112为长条形，第三延伸部113从靠近第一延伸部111的一端至远离第一延伸部111的一端的宽度逐渐减小，从而形成尖端，以方便发热体11插入烟草内。在本实施方式中，第一延伸部111及第二延伸部112为长方体状，第三延伸部113大致呈V型。在其它实施方式中，第三延伸部113也可以是U型或者等腰梯形，或者宽度从靠近第一延伸部111和第二延伸部112的一端向远离第一延伸部111和第二延伸部112的方向逐渐减小的其他形状。本实施方式中，切槽114为宽度一致的矩形或者在矩形的靠近第三延伸部113的一端形成凸向的导圆弧；具体的，切槽114为轴对称结构，其长度方向平行于其中心轴的方向，所第一延伸部111和第二延伸部112间隔并列平行设置并且长度方向平行于切槽114的中心轴方向，第一延伸部111、第二延伸部112和第三延伸部113的宽度方向垂直于切槽114的中心轴方向。发热体11为关于切槽114的中心轴对称的结构，即第一延伸部111、第二延伸部112和第三延伸部113均关于切槽114的中心轴对称的结构，此种结构，使得切槽114两侧的第一延伸部111、第二延伸部112和第三延伸部113的宽度方向相对应的位置温度一致，使烟气口感更好。
在其他实施方式中，参见图5，图6为本申请一具体实施方式提供的发热组件的平面示意图；第一延伸部111、第二延伸部112同样并列设置，但切槽114的宽度可为从远离第三延伸部113一端向靠近第三延伸部113一端逐渐减小的中心对称结构，相应的第一延伸部111、第二延伸部112外侧边平行，且宽度从远离第三延伸部113的一端向第三延伸部113一端逐渐增大。这样使远离第三延伸部113的一端的电阻略微加大，以平衡与第三延伸部113之间的电阻(第三延伸部113电阻较大)，使整体发热较为均衡。
在其他实施方式中，参见图6，图6为本申请另一具体实施方式提供的发热组件的平面示意图；切槽114可为从远离第三延伸部113一端向第三延伸部113一端逐渐增大的中心对称结构，相应的第一延伸部111、第二延伸部112外侧边平行，且第一延伸部111、第二延伸部112宽度从远离第三延伸部113的一端向第三延伸部113一端逐渐减小，使靠近发热体11上端的电阻较大，以适用发热体11高温较为集中在中上段的加热方式的设计需求。
在其他实施方式，参见图7，图7为本申请又一具体实施方式提供的发热组件的平面示意图；第一延伸部111、第二延伸部112为矩形，但不是并列平行设置，而是呈一定角度例如3-10度的角度设置，此时切槽114宽度可为从远离第三延伸部113的一端向第三延伸部113一端逐渐减小的中心对称结构。
在一具体实施例中，参见图8，图8为本申请一实施例提供的发热板的尺寸示意图；发热体11可呈图8所示的板状，其具体可为导电陶瓷制成的发热板，在该实施例中，第一延伸部111和第二延伸部112之间的间距小于整个发热体11宽度的十分之一，第一延伸部111和第二延伸部112之间的间距L1具体可为0.25-0.35毫米，以在有效保证发热体11强度的同时，避免发生短路问题。
具体的，发热板所使用的陶瓷的电阻率可为5*10 -5欧姆，设计功率可为2瓦，电阻可为0.71欧；具体的，发热板可为单根串联型式(中间设置有切槽114)，即第一延伸部111、第三延伸部113及第二延伸部112依次串联，其板厚度H1可为0.5毫米，总长度L2可为18毫米；第一延伸部111和第二延伸部112的长度L3可为16毫米，可以理解的 是，发热体11的单条有效长度可为32.0毫米；发热体11的第三延伸部113的长度可为2毫米；具体的，发热板的宽度W1可为4.0毫米；具体的，发热板的各个尺寸的误差范围不超过0.05毫米。板状的发热体11相背的两个表面均可以用于接触并加热气溶胶形成基质102。
在另一具体实施例中，参见图4和图9，图9为本申请一实施例提供的发热棒的尺寸示意图；发热体11也可呈棒状，其具体可为导电陶瓷制成的发热棒，在该实施例中，第一延伸部111和第二延伸部112之间的间距L4小于整个发热棒直径φ的三分之一，该间距L4具体可大于0小于1毫米，优选的，L4可为0.3或0.4毫米；具体的，在该实施例中，第一延伸部111和第二延伸部112之间还设置有支撑陶瓷14，以增强发热体11的强度，从而在发热体11插入烟草的过程中，能够使发热体11更加顺利地插入烟草中，有效降低了发热体11因受力而导致弯折问题发生的几率。具体的，支撑陶瓷14可通过玻璃陶瓷15与第一延伸部111和第二延伸部112粘结，以提高彼此之间的结合力。本实施方式中，支撑陶瓷14可以选用氧化锆、氧化锆增韧、氧化铝材料等陶瓷材料。
具体的，发热棒所使用的陶瓷材料的电阻率可为3*10 -5欧姆，设计功率可为3-4W，例如具体为3.3瓦，电阻可为0.3-1欧姆，例如0.5欧姆；具体的，发热棒可为单根串联型式即第一延伸部111、第三延伸部113及第二延伸部112依次串联，其直径φ具体可为2-5毫米，具体可为3毫米，长度L5可为18-22毫米，具体可为19.7毫米；其中，第一延伸部111和第二延伸部112的长度L6可为12-18毫米，具体可为16毫米，可以理解的是，发热体11的单条有效长度可为30-35毫米，具体可为32.0毫米；第三延伸部113的长度可为2-5毫米，具体可为3.7毫米；具体的，设置在第一延伸部111和第二延伸部112之间的支撑陶瓷14的长度L7可为12-18毫米，具体可为17毫米，宽度W2可与发热棒的直径φ相同，具体可为2-5毫米，具体可为3毫米，厚度H2可略小于第一延伸部111与第二延伸部112之间的间距，具体的，厚度H2可为0.8-1.2毫米，比如可为0.9毫米，以方便设置玻璃陶瓷15。
在具体实施例中，参见图1b至图4，该发热组件10还包括两个电极12，两个电极12中的其中一个电极12设置在第一延伸部111，另一个电极12设置在第二延伸部112；在具体使用过程中，两个电极12分别通过电极引线与电源组件电连接，从而使发热体11与电源组件电连接。具体的，参见图1b和图2，两个电极12分别设置在第一延伸部111和第二延伸部112远离第三延伸部113的一端的同一侧。两个电极12为导电银浆涂覆于导电陶瓷下端的外表面形成，具体的，两个电极12大致为半圆柱状并在发热体11的横截面其两端分别延伸至切槽114，如此尽可能增加与导电陶瓷的接触面积以减小接触电阻，并且具有更大的面积方便焊接电极引线，相对于现有技术丝印或镀膜形成的尺寸很小的发热线路，电极12与发热线路的接触电阻大，本申请的发热体11可以大大增加与电极12的接触面积，从而减小接触电阻，使发热体11使用的稳定性更好。
在一具体实施例中，参见图10a，图10a为本申请一实施例提供的电极设置在发热体的两个相对表面上的结构示意图；当发热体11为发热板时，可将电极12设置在第一延伸部111和第二延伸部112的相对的两个表面上，即，在第一延伸部111的端部的第一表面C和与第一表面C相背设置的第二表面D均设置一个电极12，在第二延伸部112的端部的第一表面C和与第一表面C相背设置的第二表面D均设置另一电极12，在连接两根电极引线时，可将其中一根Y形的电极引线与第一延伸部111上的两表面上的两个电极12连接，另一根Y形的电极引线与第二延伸部112上的电极12连接；当发热体11为发热棒时，参见图10b，图10b为本申请一实施例提供的发热棒的结构示意图；两个电极12可分别延伸至切槽114所对应的内壁面上；具体的，发热棒的第一延伸部111具有第一内表面111a和第一外表面111b，第二延伸部112具有第二内表面112a和第二外表面112b，第一延伸部111上的电极12从第一外表面111a延伸至第一内表面111b，第二延伸部112上的电极12从第二外表面112a延伸至第二内表面112b。通过将电极12设置在发热体11的两个表面这样不仅方便焊接，且电阻较小，通电时产生的热量较小，能够有效防止损坏。并且在导电陶瓷的两个表面同时通电，形成相同电势，有利于使两个表面之间的导电成分电场均匀，发热效果更好。
本实施方式中，切槽114贯穿第一表面C及第二表面D。进一步的，参见图10c，图10c为本申请一实施例提供的发热组件的E向视图；具体的发热体11在厚度方向上，第一延伸部111、第二延伸部112和第三延伸部113的边缘从 第一表面C与第二表面D中间平行的表面分别向第一表面C和第二表面D形成导向面118，导向面118具体可为导斜面(见图10c)或弧形，这样不仅方便插入烟草内，且能够减小阻力，从而更好的保护发热体11。
在具体实施例中，可采用涂覆的方式在第一延伸部111和第二延伸部112的两个端部形成电极12，以提高电极12与发热体11之间的结合力，从而提高连接至电极12上的电极引线与发热体11之间的连接稳定性；可以理解的是，陶瓷具有微孔结构，陶瓷的微孔结构能够使得在涂覆厚度较大的情况下仍然使形成的电极12与发热体11之间的结合力较强，从而大大提高电极12与发热体11之间的结合力。具体的，上述涂覆材料可选用银浆。可以理解也可以通过沉积金属膜的方式形成电极12，例如沉积金、铂、铜等高于1*10 -6欧姆的金属材料。
在具体实施例中，参见图11，图11为本申请一实施例提供的发热组件的侧视图；发热体11表面还可涂覆有保护层115，保护层115覆盖两个电极12，以防止加热烟草时形成的烟油损坏或污染电极12及发热体11；具体的，保护层115可为玻璃釉层。
具体的，参见图12和图13，图12为本申请一实施例提供的发热体上第一发热区和第二发热区的位置示意图；图13为本申请一实施例提供的发热棒上第一发热区和第二发热区的位置示意图；发热体11包括第一发热区A和与第一发热区A连接的第二发热区B，其中，第一发热区A为插入烟草进行加热的主要雾化区域，其上的雾化温度集中在280℃到350℃，占雾化区域面积的75％以上，第二发热区B是发热体11的主要配合段，温度在150℃以下；在一具体实施例中，发热棒的第一发热区A的长度可为14.5毫米，第二发热区B的长度可为5.2毫米。
在具体实施例中，第一延伸部111和第二延伸部112的第一发热区A和第二发热区B中仅大部分第一发热区A插入气溶胶形成基质102，而小部分的第一发热区A和第二发热区B则停留在气溶胶形成基质102的外面；或第一发热区A全部插入气溶胶形成基质102，而第二发热区B停留在气溶胶形成基质102的外面；或第一发热区A全部插入气溶胶形成基质102，且小部分第二发热区B也插入气溶胶形成基质102，仅大部分第二发热区B停留在气溶胶形成基质102的外面。
在具体实施例中，两个电极12具体设置在发热体11的第二发热区B，以降低位于第二发热区B的陶瓷发热体11的雾化温度。本实施例中，发热体11的第一发热区A的发热温度与第二发热区B的发热温度的比值大于2。
在一具体实施例中，发热体11位于第二发热区B的部分的材料的电阻率小于发热体11位于第一发热区A的部分的材料的电阻率，以使发热体11的第一发热区A的温度大于第二发热区B的温度；同时，通过在不同的发热区设置不同电阻率的材料，以通过电阻率差异调控不同发热区的温度；具体的，发热体11位于第一发热区A的部分与发热体11位于第二发热区B的部分的陶瓷材料主体成分基本相同且一体成型，但发热体11位于第一发热区A的部分与发热体11位于第二发热区B的部分的陶瓷材料的比例不同或其它组分不同，从而使得发热体11位于第一发热区A的部分与发热体11位于第二发热区B的部分的电阻率不同。相比于现有技术中，第一发热区A与第二发热区B采用不同的导电材料，例如铝膜和金膜，将两种不同的导电材料拼接的方案，能够有效避免出现发热体11的第一发热区A与第二发热区B的导电体断裂的问题。
在另一具体实施例中，参见图12，发热体11的第一延伸部111和第二延伸部112位于第二发热区B的部分的宽度或/和厚度大于发热体11的第一延伸部111和第二延伸部112位于第一发热区A的部分的宽度或/和厚度，以使发热体11的第一发热区A的温度大于第二发热区B的温度；在该实施例中，发热体11的第二发热区B的加宽的部分卡在安装座20内，以通过发热体11加宽的部分对安装座20进行限位，从而防止安装座20在插拔过程中与发热体11发生相对位移，影响电极引线与电极12之间的连接稳定性。
当然，在其他实施例中，参见图14，图14为本申请一实施例提供的发热体与安装座装配之后的结构示意图；也可以通过对材料的控制，以使发热体11的第一发热区A的温度大于第二发热区B的温度；例如发热体11下半部分增加导电成分，使下半部分的电阻更小，发热时温度更低，因此，在该实施例中，可使第一延伸部111和第二延伸部112位于第二发热区B的部分的宽度或/和厚度与第一延伸部111和第二延伸部112位于第一发热区A的部分的宽度或/和 厚度相同，从而不仅方便加工，且能够避免出现加宽部粘结烟草或烟油的问题发生。
在具体使用过程中，将发热组件10插入烟草，通电后发热组件10即开始工作，加热烟草并产生烟气。
本实施例提供的发热组件10，该发热组件10包括发热体11，该发热体11包括间隔设置的第一延伸部111和与第一延伸部111间隔设置的第二延伸部112，且该第一延伸部111及第二延伸部112均用于至少部分插入气溶胶形成基质102并在通电时产生热量以加热气溶胶形成基质102，相比于现有丝印或镀膜在基底上的发热体，本申请的发热体11能够直接、独立地插入气溶胶形成基质102，且不会出现经过高温发热时从陶瓷基底上脱落而导致失效的问题，大大提高了发热组件10的稳定性；同时，由于该发热体11为自支撑结构，无需配合基板，发热体11的两个相对的表面均可与气溶胶形成基质102直接接触，从而有效提高了发热组件10对气溶胶形成基质102的加热均匀性。
在一实施例中，参见图15至图20，其中，图15为本申请一实施例提供的固定外套的结构示意图；图16为本申请另一实施例提供的固定外套的结构示意图；图17为本申请一实施例提供的发热组件包括固定外套的结构示意图；图18为图17所示结构未装配前的结构示意图；图19为本申请另一实施例提供的发热组件包括固定外套的结构示意图；图20为图19所示结构未装配前的结构示意图。

具体的，参见图20，发热体11与固定外套13之间设置有绝缘介质层24，以增强固定外套13与发热体11之间的结合力并避免短路；具体的，绝缘介质层24可根据工艺选择涂覆在发热体11的外表面或者固定外套13的内表面，且涂覆厚度具体可为0.05-0.1毫米。在一具体实施例中，绝缘介质层24涂覆在发热体11的表面并露出切槽114及电极12。
具体的，固定外套13的长度与发热体11的长度相同或小于发热体11的长度。可以理解，由于固定外套13具有尖端，因此，第三延伸部113也可以没有尖端，便于加工。在其他实施方式中，固定外套13的纵向长度小于发热体11的长度，即有电极12的部分不被固定外套13包覆，如此，发热体11两个表面可以直接与安装座20固定，并且第一延伸部111和第二延伸部112插入烟草的部分得到加强，不会出现变形或折断情况。
参见图21至图24，其中，图21为本申请一实施例提供的安装座的结构示意图；图22为本申请一实施例提供的安装座与发热板装配之后的结构示意图；图23为本申请一实施例提供的安装座与发热棒装配之后的结构示意图；图24为本申请另一实施例提供的安装座与发热棒装配之后的结构示意图；即在具体实施例中，发热组件10使用时设置在安装座20上从而形成发热机构，且安装座20与发热组件10卡固设置，以通过该安装座20将发热组件10安装在气溶胶形成装置的主体内。具体的，当发热体11为发热板时，安装座20和发热体11装配之后的产品结构可参见图22，当发热体11为发热棒时，且发热体11外没有套设固定外套13时，安装座20发热体11装配之后的产品结构可参见图23；而当发热体11的外侧设置有固定外套13时，安装座20可根据实际情况选择安装在发热体11或者固定外套13上。例如，当固定外套13的长度与发热体11的长度相同时，安装座20可套设在固定外套13上，具体可参见图24，当固定 外套13的长度小于发热体11的长度时，发热体11的涂覆有电极12的一端暴露在固定外套13外，安装座20固定在发热体11暴露在固定外套13外的一端，即，固定在发热体11的第二发热区B，且安装座20与固定外套13靠近安装座20的一端抵接。优选地，当发热体11的涂覆有电极12的一端暴露在固定外套13外时，安装座20固定在固定外套13的开口端，即，固定外套13的开口端插入安装座20，且发热体11的涂覆有电极12的一端穿过安装座20。
