现有技术中的电热膜取暖器如中国专利文献CN107781893A，如图4所示，公开了一种电热膜发热结构，包括固定架101，若干电热膜片102，及若干瓷座103，电热膜片102上成型有通孔，瓷座103通过设置在其上的螺纹连接组件104套装于所述电热膜片102的所述通孔上从而将电热膜片102和瓷座103固定在一起，螺纹连接组件104包括插入所述通孔的螺杆以及与螺杆相配合的螺母，所述瓷座103和所述固定架101的横梁106上还分 别设置有相互适配的连接孔，所述瓷座103和所述横梁106通过穿过所述连接孔的紧固件105连接在一起，接线端子106安装在所述电热膜片102下侧表面上，通过所述瓷座103之间的间隙以及所述固定架101底部的横梁106与电热膜取暖器的发热部件相连。
上述电热膜取暖器的电热膜片上和固定架横梁上均需要开设连接孔，再通过连接件穿过上述连接孔将瓷座分别与电热膜片和固定架固定在一起，上述电热膜片安装方式具有以下问题：1.电热膜片又薄又脆容易开裂在其上下两端分别穿孔容易损伤电热膜片，需要更换新的电热膜片造成材料浪费，如果无法及时发现甚至引起电气安全隐患造成严重事故。2.每个电热膜片均需要两组连接件才能够完成安装工作，取暖器的安装过程中需要大量连接件提高了取暖器的生产成本。3.通过相互配合的螺杆和螺母对电热膜片进行固定需要预先将螺杆插入连接孔且需要两个人配合工作，一个人将电热膜片摆放至固定架的上下横梁之间另一个人将螺母拧紧，其具有安装效率低和人力成本高的问题，提高了电暖气的安装生产成本，降低了其产品竞争力。4.电热膜片上的接线端子位于瓷座以及固定架的横梁旁边，接线端子的接线过程中需要避开瓷座和横梁，接线端子处的操作空间小会导致严重影响接线端子的装配接线效率。

10.本发明提供的电热膜取暖器，通过在第一卡接梁和支撑板之间以及第二卡接梁和支撑板之间分别设置绝缘片，再分别通过连接件将支撑板和绝缘片以及卡接梁和绝缘片固定在一起从而有效地在卡接梁和支撑板之间做绝缘处理，具有绝缘效果好和安装方便的优点。
11.本发明提供的电热膜取暖器，通过将第一卡接梁和第二卡接梁设置在电热膜片其远离接线端子的位置，可以进一步地为位于电热膜片下端部的接线端子腾出接线空间，避免现有技术中的卡接梁需要设置在电热膜片两端时卡接梁会妨碍接线端子接线的问题，从而提高电热膜取暖器的装配接线效率。
12.本发明提供的电热膜取暖器，通过将多个电热膜片倾斜卡接在第一卡接梁和第二卡接梁的长度方向上，倾斜设置的电热膜片可以减少电热膜取暖器的厚度从而方便安装减小其占用空间。

此外，下面所描述的本发明不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
实施例1
本实施例提供一种电热膜取暖器，如图1和图2所示，其包括
电热膜片1，如图3所示，所述电热膜片1的下端部设置有接线端子2,每个所述电热膜片1上的所述接线端子2为两个，且所述电热膜片1的两侧分别设置有两组凸出部7，所述凸出部7设置在所述电热膜片1其外轮廓边缘的保护套10上；
固定架3，如图4所示，包括与所述电热膜片1下侧卡接相连的第一卡接梁4和与所述电热膜片1上侧卡接相连的第二卡接梁8以及分别与第一卡接梁4和第二卡接梁8卡接相连用于支撑所述电热膜片1的支撑板，所述第一卡接梁4和所述第二卡接梁8均垂直于所述电热膜片1的表面，所述第一卡接梁4上设置有供所述电热膜片1下端端部和接线端子2穿过的凸字形的第一插槽6，设置在所述电热膜片1下侧的所述凸出部7抵接在所述第一卡接梁4的上表面，所述第二卡接梁8上设置有与所述电热膜片1的上端端部相适配的第二插槽9，所述电热膜片1的该端部插入所述第二插槽9中，设置在所述电热膜片1上侧的所述凸出部7抵接在所述第二卡接梁8的下表面，凸出部设置在第一卡接梁和第二卡接梁其二者之间，使第一卡接梁可以通过其中一组凸出部限制电热膜片从朝向第一卡接梁的一端 移出，并且使第二卡接梁可以通过另外一组凸出部限制电热膜片从朝向第二卡接梁的一端移出，从而牢固可靠地将电热膜片卡接在卡接梁上，避免只设置一根卡接梁时电热膜片可以受驱动地移出卡接梁的问题，并通过电热膜片的端部插入插槽内并将电热膜片和卡接梁二者卡接相连的方式，避免了现有技术中组装电热膜取暖器时需要在电热膜片上和固定架横梁上分别开设连接孔，再通过连接件穿过上述连接孔将瓷座分别与电热膜片和固定架固定在一起，其开设连接孔容易损伤电热膜片造成电热膜片损坏和需要多个相互配合的螺杆连接件和紧固螺母才能完成上述组装工作，装配过程中配件需求多的问题，而且本申请中只需要将电热膜片插入卡接梁即可无需螺杆螺母很大程度上减小了安装难度，一个工作人员即可独立完成上述工作在降低安装难度的同时提高了安装效率；
绝缘结构，包括设置在所述第一卡接梁4和所述支撑板之间的绝缘片以及设置在所述第二卡接梁8和所述支撑板之间的绝缘片，
所述第一卡接梁4和绝缘片通过一组连接件11相连，所述支撑板和绝缘片通过另外一组连接件11相连，两组连接件11相分离使绝缘片有效地将第一卡接梁4和支撑板隔开，防止所述电热膜片1与所述支撑部件11之间导电。
在本申请中所述凸出部7设置在所述第一插槽6和所述第二插槽9的径向方向上。从而有效地增加凸出部与其相对应的第一卡板或第二卡板的连接面，使凸出部能够更好地起到限位作用限制电热膜片与卡接梁相分离。
当然，本发明申请对所述接线端子2的数量不做具体限制，在其它实施例中，每个所述电热膜片1上的接线端子2可以为四个、六个或八个等偶数个。
本实施例中电热膜取暖器的拼装步骤如下：
将第二卡接梁8的左右两端分别安装支撑板；
将固定有支撑板的第二卡接梁8倒置；
取电热膜片1将其分别插入第二卡接梁8的第二插槽9内；
将第一卡接梁4插入电热膜片1其具有接线端子2的一端；
将第一卡接梁4固定在支撑板上
将所述接线端子2连接至与其相对应的接线端上。
实施例2
本实施例与实施例1的区别在于，固定架3只有一个第一卡接梁4，具体地，所述固定架3包括与所述电热膜片1下侧卡接相连的第一卡接梁4以及分别与第一卡接梁4卡接相连用于支撑所述电热膜片1的支撑板，所述第一卡接梁4上设置有供所述电热膜片1下端端部和接线端子2穿过的凸字形的第一插槽6，设置在所述电热膜片1下侧的所述凸出部7抵接在所述第一卡接梁4的上表面，所述电热膜片1竖直设置受重力作用通过设置在所述电热膜片1下侧的所述凸出部7限制电热膜片1滑出第一卡接梁4。只设置一个卡接梁即可以完成电热膜片的固定工作还有效地降低了取暖器的生产成本。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予 以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
