Description

设置有空气夹层的线圈绕组及气溶胶生成装置 技术领域
本发明属于气溶胶生成装置领域，具体涉及电磁型烟具，更具体地涉及一种设置有空气夹层的线圈绕组和气溶胶生成装置。
背景技术
气溶胶是一种由固体或液体小质点分散并悬浮在气体介质中形成的胶体分散体系，由于气溶胶可通过呼吸系统被人体吸收，为用户提供一种新型的替代吸收方式，例如可对草本类或膏类的气溶胶生成基质烘烤加热而产生气溶胶的雾化装置，应用于不同领域中，为用户递送可供吸入的气溶胶，替代常规的产品形态及吸收方式。
现有的烘烤型气溶胶生成装置还可通过电磁感应加热原理使发热件产生热量来烘烤加热雾化气溶胶生成基质。电磁感应加热的原理是感应加热电源产生的交变电流通过感应器(即线圈)产生交变磁场，导磁性感受器(即发热体)置于其中切割交变磁力线，从而在发热体内部产生交变的电流(即涡流)，涡流使发热体内部的原子高速无规则运动，原子互相碰撞、摩擦而产生热能，从而进一步加热气溶胶生成基质。在现有电磁加热气溶胶生成装置中，一种是线圈绕组固定的支架采用直接缠绕方式进行，也就是线圈直接一圈圈紧挨着缠绕在支架上，且线圈和支架表面直接接触；另外一种是专门设置一个绕线固定支架用于缠绕线圈，而绕线固定支架内部在是管状支架。前者存在的问题是，线圈与支架紧密接触，当支架内部发热体被加热时，进行传热，导致线圈温度升高过快，加剧线损；或在内部被隔热时，线圈自发热情况下，由于线圈之间排列紧密且也是紧贴着支架，导致线圈没有空隙散热，从而使得温度过高，加剧线圈损耗。后者虽然可以将线圈和管状支架隔开，提高线圈散热，但是导致零件增加，结构复杂，更关键的线圈支架散热过快，能耗损失较大。
为了解决以上问题，提出本发明。
发明内容
本发明中所称的线圈是指呈环形的导线绕组，在本发明中尤其适用于电感领域。
本发明第一方面提供一种设置有空气夹层的线圈绕组，其包括支架主体1， 所述支架主体1外表面设置有空气槽2，线圈3缠绕在所述支架主体1外表面，且至少部分覆盖所述空气槽2，所述支架主体1和所述线圈3之间由所述空气槽2限定形成空气夹层。
可选地，所述空气槽2为多个。多个空气槽2的分布不限定，可以均匀分布也可以随机分布，更可选地是其与缠绕后线圈的分布相匹配，即线圈覆盖支架主体1的外表面就对应有空气槽2，当线圈和线圈之间设置有间隙5时，间隙5外表面也无需设置空气槽2。
可选地，所述线圈3完全覆盖所述空气槽2。也就是说，空气槽2完全位于支架主体1和线圈3之间，在缠绕线圈3后空气槽2不会暴露。
可选地，所述空气槽2轴向宽度H1小于单根所述线圈3的轴向宽度H2；所述空气槽2径向深度T大于等于0.1mm(T≥0.1mm)。在可选地实施方案中限定了空气槽2的轴向宽度和径向深度，但是并不限定空气槽的周向长度，也就是说，空气槽2可以是沿周向延伸一小段，也可以是顺着线圈的延伸方向被线圈覆盖处全部有空气槽。
可选地，所述支架主体1外表面还设置有凸起4，所述凸起4设置于所述线圈3的至少两个单个线圈之间。
可选地，所述凸起4为多个。
可选地，所述凸起4的径向高度小于等于或大于所述线圈的径向高度。也就是说，该凸起的个数、位置、轴向宽度、径向深度、周向长度均不限定，其设置只要是可以配合线圈定位缠绕，以及缠绕后线圈的固定即可。另外，对线圈进行定位，也利于线圈和空气槽的位置对应。
可选地，缠绕后至少部分所述线圈3之间设置有间隙5。相邻线圈之间均设置有间隙5也可以，或者是仅部分相邻线圈之间设置有间隙5，该间隙5可以利于线圈的散热。而凸起4的作用是对线圈定位，恰恰保证了线圈可以密绕与疏绕结合排布，从而保证间隙5的稳定存在。
本发明第二方面提供一种的气溶胶生成装置，其包括本发明第一方面所述的设置有空气夹层的线圈绕组，所述支架主体1内部设置有发热体6，所述发热体由所述线圈3感应发热。
可选地，所述线圈3外侧设置有屏蔽层9。当线圈绕制完成后，依靠屏蔽层 9自带背胶进行贴合固定，从而实现整个线圈绕制固定。
可选地，所述支架主体1顶部设置有发热体上盖7，且底部设置有发热体下盖8。
可选地，所述发热体6表面还设置有测温组件10。
本发明气溶胶生成装置为电磁型气溶胶生成装置，为了保证气溶胶生成装置正常使用，本发明的气溶胶生成装置还本领域常规的用于烟具的电源、控制器、外壳等。
相对于现有技术，本发明设置有以下有益效果：
1、本发明线圈绕组的支架主体1外表面设置有空气槽2，线圈3缠绕在所述支架主体1外表面，且至少部分覆盖所述空气槽2，利用线圈支架开空气槽的方式，形成线圈与支架之间的空气夹层，从而在所述支架主体1和所述线圈3之间形成空气隔热层，减少支架对线圈传热，减少线圈损耗。
2、进一步可选地实施方案中，所述支架主体1外表面还设置有凸起4，配合线圈定位缠绕，以及缠绕后线圈的固定即可。另外，对线圈进行定位，也利于线圈和空气槽的位置对应。
3、进一步可选地实施方案中，缠绕后至少部分所述线圈3之间设置有间隙5，线圈自身热量可通过该间隙5实现散发。
4、经过本模组实测对比，带空气槽的线圈支架方案比普通贴合绕制的方案，模组温度(即加热单元最外层屏蔽层的温度)降低6.53℃，线圈引线表面温度降低4.43℃，有效降低了线圈表面温度，从而实现减少线圈损耗的效果。
5、经过本模组实测对比，带空气槽的线圈支架方案比单独绕线固定支架的普通方案，能耗低14mwh左右，达到进一步降低器具的整体能耗的技术效果。

对比例1
现有的电磁型气溶胶生成装置，其线圈支架表面没有空气槽2，也没有凸起，相应的线圈是直接一圈圈紧挨着缠绕在支架上，且线圈和支架表面直接接触。
对比例2
现有的电磁型气溶胶生成装置，其专门设置一个绕线固定支架用于缠绕线圈，而绕线固定支架内部在是管状支架，线圈紧密缠绕在绕线支架上。
实施例
如图1-5，本发明实施例提供一种设置有空气夹层的线圈绕组以及包括所述设置有空气夹层的线圈绕组的气溶胶生成装置。
其中，所述设置有空气夹层的线圈绕组包括支架主体1，所述支架主体1外表面设置有空气槽2，线圈3缠绕于所述支架主体1外表面，且至少部分覆盖所述空气槽2，所述支架主体1和所述线圈3之间由所述空气槽2限定形成空气夹层。从而在所述支架主体1和所述线圈3之间形成空气隔热层，减少热量向线圈3的传递，减少线圈损耗。
示例性的，所述空气槽2为多个，其与缠绕后线圈的分布相匹配，即覆盖有线圈的支架主体1的外表面就对应设置有空气槽2，未覆盖线圈的支架主体1的外表面不设置空气槽2。例如，在一个可选的实施方式中，当线圈的单个线圈之间设置有间隙5的状态下，则对应间隙5处的所述支架主体1的外表面不设置空气槽2。
示例性的，所述线圈3完全覆盖所述空气槽2。由于已经完全覆盖空气槽2，使得线圈与支架之间的空气层相对密闭，从而在线圈与支架之间形成空气隔热层，能更好的减少支架对线圈传热减少线圈损耗。
如图2所示，假设空气槽2轴向宽度为H1，线圈3的轴向宽度为H2，则在H1小于或等于H2的状态下，单根线圈能相对密封支架上的空气槽，这样，在线圈与支架之间形成相对密封的空气槽，达到利用空气隔热的技术效果。示例性的，所述空气槽2轴向宽度H1＝1.0mm，单根所述线圈3的轴向宽度H2＝1.65mm，小于单根所述线圈3的轴向宽度H2＝1.65mm；又如，所述空气槽2径向深度T＝0.3mm。
如图3所示，示例性的，所述支架主体1外表面还设置有凸起4，所述凸起4设置于所述线圈3的至少两个单个线圈之间。所述凸起4为一个或多个，一般情况下为多个。凸起4用于线圈绕组的绕线，起到对线圈绕组的固定和定位作用。在一些可选的实施例中，线圈绕组的线圈之间设置间距，以达到对线圈的自发热进行更好的散热的技术效果。通过对凸起位置和大小的设定，可以控制线圈绕组在绕线时单个线圈之间的间距。一般来说，凸起4的位置和大小与线圈绕组的单个线圈的尺寸相适应，以达到理想的散热效果。例如，在一个可选的实施例中，如图3所示，所述凸起4的径向高度H3＝0.5mm，所述线圈的径向高度H4＝0.8mm，其中凸起4的径向高度H3小于所述线圈的径向高度H4能更好地对线圈进行定位。因凸起属于支架一部分，也会传导一部分热量，在另一个可选的实施例中，凸起4的径向高度H3小于线圈的径向高度H4，则凸起4既可以实现对线圈绕组的定位作用，也使得线圈与支架的接触尽可能少，从而实现增加线圈散热面积，又减少支架对线圈的热传导的技术效果。
线圈绕组缠绕线圈后至少部分所述线圈3之间设置有间隙5。其中，缠绕后线圈之间的间隙5可均匀设置，也可非均匀设置。示例性的，如图1中，线圈缠绕后按照轴向大体是分为三个部分，其中上下各有3-4圈线圈，而中间设置有1圈线圈，中间层线圈和上下线圈之间各设置有1个间隙5，相应的中间层线圈两侧设置有凸起4。通过凸起4实现线圈的定位以及间隙的设置。其中，上部、下部各3-4圈线圈之间的间距相对上部与中间、下部与中间的间距小，即相对来说，上部、下部各3-4圈线圈之间属于密绕，中间线圈属于疏绕，线圈间的间距也可以是渐变式的。本实施方式中通过对线圈以密绕与疏绕相结合的排布方式，这些间距可以让线圈的自发热得到较好的散热，使得可根据不同的产品设计不同的散热方式。
本发明实施例提供的气溶胶生成装置包括上述实施例所述的设置有空气夹层的线圈绕组1，所述支架主体1内部设置有发热体6，在一般情况下，所述线圈3外侧设置有屏蔽层9。在一些可选的实施方式中，所述支架主体1顶部设置有发热体上盖7，且底部设置有发热体下盖8。在一些可选的实施方式中，所述发热体6表面还设置有测温组件10。
经过本模组实测对比，本实施例带空气槽的线圈支架方案比对比例1普通贴 合绕制的方案，模组表面温度降低6.53℃，线圈引线表面温度降低4.43℃。具体数据请见表1普通方案与空气层方案的温度对照表。
表1普通方案与空气层方案的温度对照表
                                                  单位：℃
经过本模组实测对比，本实施例带空气槽的线圈支架方案比对比例2单独绕线固定支架的普通方案，能耗低14mwh左右。具体数据请见表2普通方案与空气层方案的能耗对照表。
表2普通方案与空气层方案的能耗对照表
                                                   单位：mwh
本发明实施例提供的线圈绕组及气溶胶生成装置，通过在支架主体外表面设置空气槽，从而形成线圈与支架之间的空气层，减少支架对线圈的传热，同时通过凸起在单个线圈之间设置间隙，利于线圈自发热散热，减少线圈损耗。相对现有技术，能显著降低能耗以及模组温度，降低模组损耗。
以上所述仅为本发明的实施例，并非因此限制本申请的专利范围，凡是利用本申请所命书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
