Description

加热器及雾化装置
申请要求于2022年2月18日提交中国专利局、申请号为202220344718.2、申请名称为“加热器及雾化装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于加热雾化技术领域，尤其涉及一种加热器及雾化装置。
背景技术
对于目前的加热不燃烧(仅通过加热实现雾化，不产生燃烧反应)雾化装置市场来说，主要加热方式包括电阻加热和电磁加热。在电磁加热方式中，电磁加热器和电磁线圈线路层缺一不可，而且电磁线圈线路层的制作方式对于整个产品影响比较大。
加热不燃烧雾化装置中应用的电磁线圈线路层的一般都是采用圆形直绕的方式。绕制线圈材料形状有好几种，例如单股铜线绕制、多股铜线绕制。单股铜线绕制和多股铜线绕制的加热线圈，一般需要围绕线圈支架去绕制才能保证电磁线圈线路层的一致性。但是铜线需要过大电流，直径比较粗，再加上线圈支架的尺寸和隔热材料尺寸，整体产品尺寸较大，不便于产品的小型化发展。

请参阅图1，图1是本申请一实施例提供的一种雾化装置的剖面示意图。

可选的，本申请所述的雾化装置100还可以是医用雾化设备、加湿器、微型雾化装置、电子雾化装置、电子烟等。
请参阅图2及图3，图2是本申请一实施例提供的一种加热器的侧视图，图3是本申请第一实施例提供的一种加热器的剖面示意图。
加热器10包括管状件2和卷绕于管状件2外的柔性印刷线圈4。管状件2用于收容待雾化物，并提供待雾化物的雾化场所。柔性印刷线圈4包括柔性绝缘薄膜42和线圈线路层44。柔性绝缘薄膜42套设于管状件2外，线圈线路层44设于柔性绝缘薄膜42上并环绕管状件2的轴向设置。线圈线路层44通电后产生磁场，通过控制通过线圈线路层44电流的大小或者频率，以使线圈线路层44产生变化的磁场。
本申请提供的加热器10，通过将线圈线路层44设于柔性绝缘薄膜42上，线圈线路层44卷绕于管状件2外。因为线圈线路层44无需围绕线圈支架绕制，有利于简化工艺制程，提高生产效率。区别于传统的铜线绕制，本申请通过将线圈线路层44设于柔性绝缘薄膜42上， 由于柔性绝缘薄膜42较薄，有利于减小加热器10的径向尺寸，有利于加热器10的小型化发展。柔性绝缘薄膜42可随意弯曲，有利于提高柔性印刷线圈4卷绕于管状件2外。同时，本申请第一实施例提供的加热器10的管状件2的材质为磁性材料，例如低碳钢、铁镍合金等铁磁体或者顺磁体。管状件2不仅提供待雾化物的雾化场所，还用于在变化的磁场中加热待雾化物，加热器10无需额外设置加热元件加热待雾化物，以使加热器10的结构更加简单，制作难度较低，有利于提高加热器10的生产效率，有利于加热器10的小型化发展。
本申请的一些实施例中，以柔性印刷线圈4为柔性电路板(Flexible Printed Circuit，简称FPC)为例进行阐述，柔性电路板是以聚脂薄膜或者聚酰亚胺为基材制成的一种具有高可靠度和曲挠性的印刷电路板。
由于柔性线路板相较于铜线更加耐高温，使用柔性线路板为基材形成柔性印刷线圈4的耐高温性能较传统的铜线绕制的线圈耐高温性能好，进而使得柔性印刷线圈4在使用的过程中安全性更好。
具体的，柔性电路板包括绝缘薄膜、导体以及粘接剂。绝缘薄膜有很多种材料，由于柔性电路板需具有非依然性，几何尺寸稳定，具有较高的抗扯强度，并具有耐高温(250摄氏度以上)的特点，绝缘薄膜的材料可以是聚酯材料和聚酰亚胺等绝缘材料。导体可以用铜箔，铜箔基本分成电解铜和压延铜两种。铜箔可以采用电淀积(Electrodeposited，ED)，或者镀制制成。导体是具有柔顺性的材料，可以被制成多种厚度和宽度，导体除了具有柔顺性以外，还具有硬质平滑的特点。粘结剂不仅用于将绝缘薄膜粘接至导电铜箔上，也可以用作覆盖层，作为防护性涂覆，以及覆盖性涂覆。
可选的，柔性绝缘薄膜42的层数包括但不限于单层或者多层。
可以理解的，在其他的实施方式中，柔性绝缘薄膜42还可以是其他可靠度高、曲挠性好、重量轻、体积小、散热性好、安装方便的其他基材。
线圈线路层44(导体铜箔)通过刻蚀或其他工艺形成于柔性绝缘薄膜42上，有利于提高线圈线路层44的制作精度，使得线圈线路层44的电感量一致性较好，有利于使得加热器10的工作效率一致性较好。由于柔性绝缘薄膜42较薄，对于刻蚀形成的线圈线路层44，可以减小相邻的线圈之间因横截面积等原因形成的电容能量损失。
可选的，线圈线路层44的层数包括但不限于单层铜箔或者多层铜箔，当线圈线路层44为多层铜箔时，任意相邻的两层铜箔之间绝缘设置。
请参阅图4，图4是本申请第一实施例提供的一种加热器的层叠结构剖面示意图。
本申请第一实施例提供的加热器10还包括第一隔热层12、磁屏蔽层14及第二隔热层16。
第一隔热层12设于管状件2外，且第一隔热层12夹设于管状件2与柔性印刷线圈4之间，第一隔热层12用于对管状件2进行隔热和保温。通过第一隔热层12的隔热作用，以减少管状件2对线圈线路层44的影响。通过第一隔热层12的保温作用，以使管状件2内的热量散失较小，提高加热器10的雾化效率。
磁屏蔽层14设于柔性印刷线圈4背离管状件2的一侧，磁屏蔽层14用于对线圈线路层44进行隔离，减少外界磁场或者电场对线圈线路层44的影响，进而提高加热器10工作的稳定性。第二隔热层16设于所述柔性印刷线圈4背离所述管状件2的外围，具体地，第二隔热层16设于磁屏蔽层14背离柔性印刷线圈4的一侧。
第二隔热层16用于对加热器10整体进行隔热和保温，以使加热器10在较低温度的环境下能够正常使用。
在其他的实施方式中，为使加热器10的结构更加简单，可以省略磁屏蔽层14和/或第二 隔热层16，这样有利于加热器10的小型化发展。

在其他的实施方式中，N的数值可以根据管状件2的高度或者雾化需求设定，N的取值可以是2，3，4，5，6等大于或者等于2的正整数。可以理解的，N的数值也可以是1，即线圈线路层44仅包括一个线圈单元，只要能产生磁场即可，本发明对此不作限定。
本申请实施例中，第1线圈单元44a、第2线圈单元44b、第3线圈单元44c及第4线圈单元44d皆为等距离设置的平行线，且第1线圈单元44a、第2线圈单元44b、第3线圈单元44c及第4线圈单元44d相对于柔性印刷线圈4的径向倾斜，以便于形成规则的螺旋状线圈线路层44，有利于线圈线路层44形成稳定的变化磁场，进而使得加热器10的加热更加稳定。
可以理解的，在其他的实施方式中，根据雾化加热的需求，第1线圈单元44a、第2线圈单元44b、第3线圈单元44c及第4线圈单元44d还可以呈曲线形状，第1线圈单元44a、第2线圈单元44b、第3线圈单元44c及第4线圈单元44d之间可以不等距离设置。

进一步地，线圈线路层44还包括第一延伸部446与第二延伸部448，第一延伸部446设于靠近柔性绝缘薄膜42底部的位置，第二延伸部448设于靠近柔性绝缘薄膜42顶部的位置。N个线圈单元440位于第一延伸部446与第二延伸部448之间，第一延伸部446与第1线圈单元44a电性连接。第二延伸部448与第4线圈单元44d电性连接。
具体的，柔性绝缘薄膜42沿管状件2的轴向包括相对设置的第一边缘422与第二边缘424。第一延伸部446设于第一边缘422与N个线圈单元440之间，且第一延伸部446的一端与N个线圈单元440中的第1线圈单元44a的第二连接部48电性连接。第二延伸部448设于第二边缘424与N个线圈单元440之间，且第二延伸部448的一端与N个线圈单元440中的第N线圈单元的第一连接部46电性连接。
具体的，线圈线路层44还包括设于第一延伸部446上靠近第一安装端442的第三连接部4462，第三连接部4462与第1线圈单元44a上的第二连接部48电性连接。线圈线路层44还包括设于第二延伸部448上靠近第二安装端444的第四连接部4482，第四连接部4482与第4线圈单元44d的第一连接部46电性连接。

请参阅图6，图6是本申请一实施例提供的一种柔性印刷线圈的结构示意图。
本申请实施例中，柔性绝缘薄膜42包括相对设置的第一表面426与第二表面428，第一表面426朝向管状件2设置，线圈线路层44设于第一表面426上。
在其他的实施方式中，线圈线路层44可以设于第二表面428上，或者，线圈线路层44嵌设于柔性绝缘薄膜42中。
请参阅图7，图7是本申请第二实施例提供的一种加热器的剖面示意图。
本申请第二实施例提供的加热器10与本申请第一实施例提供的加热器10大致相同，其不同之处在于，本申请第二实施例提供的加热器10还包括加热芯6，管状件2具有容纳待雾化物的空腔22，空腔22沿管状件2的轴向贯穿管状件2，加热芯6至少部分自管状件2的底部伸入空腔22内。在本申请第二实施例中，管状件2可以为非金属材质，加热芯6的至少部分为金属材质。加热芯6在线圈线路层44产生的变化磁场中发热，进而使得雾化待雾化物受热雾化并形成雾化气体，雾化气体从管状件2的顶部释放。
具体的，加热芯6包括金属棒62和导热件64，导热件64覆盖于金属棒62的外围，即金属棒62包裹在导热件64内。至少部分金属棒62和至少部分导热件64从管状件2的底部伸入空腔22内，且导热件64的导热系数小于金属棒62的导热系数。其中，金属棒62在线圈线路层44产生的变化磁场中发热。
本申请二实施例中，导热件64的材料为陶瓷，通过导热件64将金属棒62的热量均匀地传递到管状件2的空腔22内，以使容纳于管状件2的空腔22内的待雾化物均匀受热，有利于提高待雾化物受热雾化的质量。由于导热件64的导热系数小于金属棒62的导热系数(导热件64的散热较金属棒62的散热慢)，使得导热件64对金属棒62具有保温作用，可以有效地减少能量的损失，提高能量的利用率。
请参阅图8，图8是本申请第二实施例提供的一种加热器的层叠结构剖面示意图。
本申请第二实施例提供的加热器10还包括磁屏蔽层14及第二隔热层16。磁屏蔽层14设于柔性印刷线圈4背离管状件2的一侧，磁屏蔽层14用于对线圈线路层44进行隔离，减少外界磁场或者电场对线圈线路层44的影响，进而提高加热器10工作的稳定性。第二隔热 层16设于磁屏蔽层14背离柔性印刷线圈4的一侧，第二隔热层16用于对加热器10整体进行隔热和保温，以使加热器10在较低温度的环境下能够正常使用。
在其他的实施方式中，为使加热器10的结构更加简单，可以省略磁屏蔽层14和/或第二隔热层16，这样有利于加热器10的小型化发展。
加热器10还包括测温线路8，测温线路8与主控电路(图未示出)电性连接，测温线路8用于实时检测加热器10的温度，通过测温线路8控制加热器10的通断电，进而对加热器10实现过热保护。
由于加热器10在工作过程中会发热，当加热器10发热失控时(加热电路不能及时停止工作)加热器10会出现过热的情况，通过测温线路8对加热器10的温度进行实时检测，并通过测温线路8实现断电或者其他能够使得加热电路停止工作的方法提高加热器10工作过程中的安全性，不仅可以保护加热器10不会因为过热而烧毁，还可以避免用户使用加热器10的过程中烫伤。
具体的，测温线路8包括第一测温线路82及第二测温线路84，第一测温线路82、第二测温线路84、线圈线路层44及加热芯6皆与主控线路电性连接。第一测温线路82设于柔性绝缘薄膜42上，第一测温线路82用于实时检测线圈线路层44的温度。第二测温线路84设于加热芯6上，第二测温线路84与导热件64一体成型，第二测温线路84用于实时检测加热芯6的温度。通过设置第一测温线路82及第二测温线路84分别对线圈线路层44和加热芯6进行实时温度检测，以使测温线路8的工作更加稳定，测温线路8对加热器10的过热保护更可靠。
相较于传统的加热器件与测温器件分离设置的方式，本申请的第一测温线路82设于柔性绝缘薄膜42上，第二测温线路84设于加热芯6上。通过线圈线路层44与第一测温线路82集成设计，以及加热芯6与第二测温线路84集成设计，有利于减小加热器10的组装难度，提高测温线路8对加热器10进行温度测量的精准性。
本申请提供的加热器10集电磁感应加热、温度测量、温度传导和保温于一体，有利于优化产品设计和生产组装的复杂性。
以上是本申请的部分实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
