在一些实施例中,感应线圈50的外径尺寸d5介于10mm~20mm;在一个具体的实施例中,感应线圈50的外径尺寸d5为15.7mm。
如图2和图3中所示,绕成螺线管的感应线圈50的匝数或绕组大约8匝到30匝的范围内。感应线圈50的相邻匝数或绕组之间的间距大约为0.1mm~0.5mm。相应地,内体积可能在大约0.10cm 3至大约2.50cm 3的范围内。
在2和图3所示的实施例中,感应线圈50的导线材料的截面基本是矩形的形状。
或者在一些更多的变化实施例中,感应线圈50的导线材料的截面还可以为更多的规则或不规则的形状。例如图4示出了又一个变化实施例的感应线圈50a的示意图;该感应线圈50a的导线材料的截面大致是椭圆形状;同样地,感应线圈50a的导线材料沿径向方向的延伸尺寸d1大于沿轴向方向的延伸尺寸d2。又例如图5示出了又一个变化实施例的感应线圈50b的示意图;该感应线圈50b的导线材料的截面大致是梯形形状。
在以上所示的实施例中,感应线圈50/50a/50b的相邻匝数或绕组之间的间距是相同的。
或者在又一些变化的实施例中,感应线圈50/50a/50b的相邻匝数或绕组之间的间距是变化的。例如在一些实施例中,感应线圈50/50a/50b的相邻匝数或绕组之间的间距沿轴向方向是逐渐增大或减小的。较低的间距(其中绕组之间的距离较小)可能导致更强的磁场生成。较高的间距(其中绕组之间的距离较大)可能导致较弱的磁场生成。不同强度磁场导致感受器30相邻部分中的不同 强度涡电流,并且导致不同的温度。因此,在感应加热的操作期间,不同的间距可导致感受器30中的温度梯度的产生。
采用以上感应线圈50/50a/50b,相比常规的截面为圆形的导线材料绕制的线圈,在导线材料在轴向方向上占据更低的尺寸,进而感应线圈50/50a/50b在单位长度上可以具有更多的线圈匝数或绕组。具体,例如采用截面中第二尺寸d2为0.6mm的导线制备的感应线圈50时,在横截面积与普通直径1mm圆形导线相同的情况下,侧向延伸第一尺寸d1为1.3mm;在相同高度例如6mm情况下,常规圆形线圈绕6匝,使用这种扁线的这种绕制方法可以绕9~10匝。进一步根据磁路中线圈电感的计算公式:L=N 2/R Σ;式中,N为线圈的匝数或绕组,R Σ为整个磁路的等效磁阻;采用以上感应线圈50/50a/50b相比圆形导线材料绕制的线圈匝数增大至2倍时,电感值能提升4倍;使感应加热过程中具有更大的频率适应性。
或者图4示出了又一个优选的实施例的感应线圈50d的示意图;该实施例的感应线圈50d包括:
沿轴向方向依次布置的部分510d和部分520d;并且其中在线圈的部分520d中每单位长度的绕组或匝数小于在部分510d中每单位长度的绕组或匝数。在实施例中使感受器30相邻部分中的不同强度涡电流,并且导致不同的温度。因此,在感应加热的操作期间,不同的间距可导致感受器30中的温度梯度的产生。温度梯度的方向可取决于感受器30与感应线圈520d在轴向方向上的相对位置的定向。
以及图6所示的感应线圈50d中,部分510d靠近感应线圈50d的第一端;感应线圈50d中还包括靠近第二端的部分530d,部分520d位于部分510d和部分530d之间。同样地,部分520d中每单位长度的绕组或匝数小于在部分530d中每单位长度的绕组或匝数。则在该实施例中,可使感受器30中较难散热的中央区域的温度与两端散热较快的部分的温度趋于均匀。
根据图6中所示,感应线圈50d的部分510d和/或部分530d的延伸长度是大于部分520d的。以及感应线圈50d的部分510d和/或部分530d的匝数或绕组是大于部分520d的。
图7示出了又一个实施例的气雾生成装置的示意图,该实施例的气雾生成 装置包括:
存储有液体气溶胶生成基质并对其进行汽化生成气溶胶的雾化器200e、以及为雾化器200e供电的电源组件100e。在该实施例中,气溶胶生成基质是液态的,通常包括有液态的尼古丁或尼古丁盐、甘油、丙二醇等,在被加热时汽化生成可供吸食的气溶胶。
雾化器200e包括:
储液腔210e,以用于存储液体气溶胶生成基质;
导液元件220e,至少部分延伸至储液腔210e内以吸取液体气溶胶生成基质;
感受体30e,结合于导液元件220e上,以在被变化的磁场穿透时发热以加热导液元件220e内的部分液体基质生成气溶胶。在一些可选的实施中,导液元件220e是棒状或管状或杆状等形状;导液元件220e可以采用纤维棉、海绵体、多孔陶瓷体等具有多孔材料制备,进而能通过内部的毛细作用吸取和传递液体气溶胶生成基质;感受体30e可以是围绕导液元件220e的感受性的条带、管、或网等。
电源组件100e包括:
设置于沿长度方向的一端的接收腔130e,在使用中雾化器200e的至少部分可移除地接收于接收腔130e;
感应线圈50e,至少部分围绕接收腔130e,以用于产生变化的磁场;
用于供电的电芯110e;
电路120e,通过适当的电连接到可充电的电芯110e,用于从将电芯110e输出的直流电流,转变成具有适合频率的交变电流再供应到感应线圈50e。
同样地感应线圈50e的导线材料在沿径向方向的延伸尺寸大于沿轴向方向的延伸尺寸。
或者又一个变化的实施例中,图8示出了又一个实施例的导液元件220f的示意图;导液元件220f至少部分表面用于与储液腔210e流体连通,以接收液体气溶胶生成基质;导液元件220f具有平坦延伸的雾化面221f;感受体30f通过表面贴装、共烧、沉积等方式结合于雾化面221f上,并通过被变化的磁场穿透而发热以加热液体气溶胶生成基质生成气溶胶。感受体30f上具有镂空31f,进而界定用于供气溶胶从雾化面221f溢出的通道。或者在一些实施中,感受体30f可以是网状、条带状或蜿蜒迂回的形状等。
