参阅图1，本实用新型一实施例提供了一种雾化器100，包括主机身10、供电模块20、控制模块30以及雾化管40。其中，供电模块20安装于主机身10内，用于为雾化器100提供电能。控制模块30用于根据用户操作控制雾化器100的工作状态。雾化管40外绕设有电 感线圈50，电感线圈50可在交变电流的供应下产生可穿透雾化管50的交变磁场，从而诱导雾化管50反应发热以加热气溶胶生成基质产生气溶胶。
下面将以不同实施例作为范例，对本申请雾化器100中雾化管40的结构及实施方式分别进行详细介绍。但以下实施例仅作为范例说明，并不会限制本申请的技术范围。另外，为了区别起见，雾化管40的标号将在不同实施例中进行区别示出，在此不作赘述。
请参阅图2及图3，在第一实施例中，雾化管40a大致呈柱状结构，其形成沿轴向方向两端开口的雾化腔412a，气溶胶生成基质可从雾化管40a的一端开口执行插拔操作。雾化管40a包括中间段及沿自身轴向布置于中间段至少一端的连接段，中间段被构造为发热区域，至少一个连接段被构造为非发热区域，发热区域可发热以烘烤气溶胶生成基质，非发热区域则始终保持较低的温度。
如此，由于发热区域的轴向方向上的至少一端设有非发热区域，因此发热区域产生的热量在非发热区域的阻挡下不易传导至位于雾化管40a的轴向方向上的其它部件，进而防止过高的温度影响这些部件的使用寿命，同时避免了能源的浪费。
作为一较佳的实施方式，中间段在雾化管40a轴向方向上的两端均设置连接段，两个连接段均被构造为非发热区域。如此，非发热区域设置于雾化管40a轴向的两端，发热区域位于两个非发热区域之间。因此，由发热区域产生的热量可由位于其轴向两端的非发热区域阻挡，防止热量沿其轴向的两端传导。
可以理解，在其它一些实施例中，非发热区域仅设置于发热区域在雾化管40a的轴向的其中一端，从而阻止雾化管40a的热量向设有非发热区域的一端传导亦可，在此不作限定。
具体地，本申请的第一实施例的雾化管40a，包括主管体41a和发热层43a，主管体41a呈中空的圆柱状结构以形成两端开口的雾化腔412a，发热层43a沿周向环绕主管体41a的中部以形成沿周向环绕雾化管40a的发热区域，发热层43a在雾化管40a的轴向方向上的两端边缘与主管体41a的端面间隔设置以形成未设有发热层43a的非发热区域。如此，发热层43a发出热量通过主管体41a传到至雾化腔412a中的气溶胶生成基质以产生气溶胶，而未覆盖有发热层43a的主管体41a则可阻止热量传导至位于雾化管40a的轴向两端的其它部件。
进一步地，主管体41a的内表面凸设至少一条伸入雾化腔412a的限位筋414a，限位筋414a可挤压气溶胶生成基质以压缩气溶胶生成基质的周向尺寸，从而缩短热量的传导距离，有助于发热层43a的热量传递至气溶胶生成基质内部。具体地，主管体41a设有3-8条限位筋414，在一些实施例中为4-6条，每条限位筋414a自主管体41a的一端沿主管体41a的轴向方向延伸至主管体41a的另一端。可以理解，限位筋414a的数量与排布方式不限于此，可根据需要设置以满足不同要求。
更进一步地，由于发热层43a的中部温度集中，因此发热层43a开设至少一个连通雾化腔的贯通孔432a，从而防止发热层43a的中部温度过高，进而使传导至主管体41a的热量更 加均匀，保证气溶胶生成量的一致性。具体地，发热层43a开设3-8个贯通孔432a，在一些实施例中为4-6个，每个贯通孔432a呈沿主管体41a的轴向方向延伸的腰型孔。可以理解，贯通孔432a的数量、排布以及形状方式不限，可根据需要设置以满足不同要求。
在第一实施例中，主管体41a为不会因电感线圈50产生的交变磁场发热的弱导磁材料制成，弱导磁材料具体为非磁性金属或弱磁性金属，例如铝、铜或3系列不锈钢(例如316L和304)，主管体41a的管壁厚度为0.5mm-0.3mm，在一些实施例中为0.1mm-0.15mm。发热层43a为可因电感线圈50产生的交变磁场发热的强导磁材料制成，强导磁材料具体为磁性金属，例如高居里温度磁性金属(例如镍基合金和铁基合金)或4系列不锈钢(例如430)，其中居里温度为220℃-260℃，在一些实施例中为230℃-250℃。发热层43a在主管体41a轴向的两端边缘与主管体41a的端面之间的距离(即非发热区域在雾化管40a轴向上的宽度)为1mm-5mm，在一些实施例中为2mm-3mm，发热层43的厚度为0.05mm-0.3mm，在一些实施例中为0.1mm-0.15mm。可以理解，主管体41a和发热层43a的尺寸、材料不限于此，可根据需要设置以满足不同需要。
如图4及图5所示，本申请的第二实施例的雾化管40b，包括主管体41b和发热层43b。主管体41b呈中空柱状结构，且包括交替设置的平面P和弧形面C，发热层43b设于至少一个平面P上，以形成对气溶胶生成基质进行烘烤的发热区域。同时，由于平面P可用于挤压气溶胶生成基质以压缩气溶胶生成基质的周向尺寸，从而缩短热量的传导距离，有助于发热层43b的热量传递至气溶胶生成基质内部。
具体地，主管体41b的横截面大致呈三角形，包括三个交替设置的平面P和三个连接平面的弧形面C，三个平面P同时贴合并挤压气溶胶生成基质，每个平面P上均设置一矩形的发热层43b以形成三个发热区域。如此，三个发热层43b产生的热量通过三个平面传递至气溶胶生成基质。
在第二实施例中，主管体41b为不会因电感线圈50产生的交变磁场发热的弱导磁材料制成，弱导磁材料具体为非磁性金属或弱磁性金属，例如铝、铜或3系列不锈钢(例如316L和304)形成，主管体41b的管壁厚度为0.5mm-0.3mm，在一些实施例中为0.1mm-0.15mm。发热层43b为可因电感线圈50产生的交变磁场发热的强导磁材料制成，强导磁材料具体为磁性金属，例如高居里温度磁性金属(例如镍基合金和铁基合金)或4系列不锈钢(例如430)形成，其中居里温度为220℃-260℃，在一些实施例中为230℃-250℃。每个发热层43b在主管体41b的轴向方向上的两端边缘与主管体41b的端面之间的距离为1mm-5mm，在一些实施例中为2mm-3mm，发热层43b的厚度为0.05mm-0.3mm，在一些实施例中为0.08mm-0.15mm。可以理解，主管体41b和发热层43b的尺寸、材料不限于此，可根据需要设置以满足不同需要。
如图6所示，本申请的第三实施例的雾化管40c，包括发热管41c与屏蔽层43c，两个屏 蔽层43c分别沿周向环绕发热管41c的相对两端的外表面以形成两个非发热区域，且每个屏蔽层43c的内表面与发热管41c的外表面完全贴合，发热管41c未覆盖屏蔽层43c的外表面形成发热区域。如此，发热管41c可产生热量以烘烤雾化腔内的气溶胶生成基质，屏蔽层43c则起到控制温度场分布的作用，达到阻止发热管41c两端的热量向外部传递的效果。
进一步地，发热管41c被配置为导磁材料制成，可因电感线圈50产生的交变磁场发热。屏蔽层43c可被配置为隔热材料形成的热屏蔽层以屏蔽发热管41c散发的热量，也可被配置为磁屏蔽材料形成的磁屏蔽层以防止发热管41c被其覆盖的部分发热。
在第三实施例中，发热管41c由磁性金属，例如高居里温度磁性金属(例如镍基合金、铁基合金)和4系列不锈钢形成，其中居里温度为220℃-260℃，在一些实施例中为230℃-250℃。发热管41c的管壁厚度为0.05mm-0.3mm，在一些实施例中为0.08mm-0.15mm。屏蔽层43c由非磁性高导电金属，例如铁氧体、铜、铝、银、3系列不锈钢(例如316L)形成，屏蔽层43c的厚度为0.05mm-0.3mm，在一些实施例中为0.08mm-0.15mm。可以理解，发热管41c和屏蔽层43c的尺寸、材料不限于此，可根据需要设置以满足不同需要。
如图7所示，本申请的第四实施例的雾化管40d，包括发热管41d与屏蔽层43d，两个屏蔽层43d分别沿周向环绕发热管41d的相对两端的外表面以形成两个非发热区域，发热管41d未覆盖屏蔽层43d的外表面形成发热区域。
进一步地，发热管41d被配置为导磁材料制成，可因电感线圈50产生的交变磁场发热。屏蔽层43d可被配置为隔热材料形成的热屏蔽层以屏蔽发热管41d散发的热量，也可被配置为磁屏蔽材料形成的磁屏蔽层以防止发热管41d被其覆盖的部分发热。
进一步地在第四实施例中，每个屏蔽层43d的内表面与发热管41d的外表面部分接触而存在一定间隙，从而可进一步阻止发热管41d的热量向外传递。
具体地，屏蔽层43d包括沿周向设置的多段间隔部741和多个接触部743，每个接触部743连接相邻两个间隔部741，接触部743与发热管41d接触以使屏蔽层43d固接于发热管41d，间隔部741与发热管41d间隔设置而形成隔热间隙，从而进一步阻止发热管41d的热量向外传递。
在第四实施例中，发热管41d由磁性金属，例如高居里温度磁性金属(例如镍基合金、铁基合金)和4系列不锈钢形成，其中居里温度为220℃-260℃，在一些实施例中为230℃-250℃。发热管41d的管壁厚度为0.05mm-0.3mm，在一些实施例中为0.08mm-0.15mm。屏蔽层43d由金属铜、铝、银、3系列不锈钢(例如316L)或者磁性材料铁氧体(在一些实施例中为铁氧体)形成，屏蔽层43d的厚度为0.2mm-5mm，在一些实施例中为3mm-4mm。可以理解，发热管41d和屏蔽层43d的尺寸、材料不限于此，可根据需要设置以满足不同需要。
上述雾化管40和设有其的雾化器100，通过在雾化管40上设置发热区域和位于发热区域两端的非发热区域，有效防止了雾化管40发热产生的热量传递至雾化器100中的其它部件， 提高了加热效率，减少了能源的浪费，同时防止其它部件因高温而损坏。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
