图6是已知电热封口机示意图。
具体实施方式
请参阅图1及图2，图1是本发明一较佳实施例的电热模组的组合图，图2是本发明一较佳实施例的电热模组的组合图。
如图所示，一种电热封口机用的可换电热模组10，其包括一下盖20，其具有一第一导电片21、一第二导电片22及一壳体23，该壳体23具有一弹簧容置槽24；一具有一镂空窗31的上盖30，该上盖30是供盖合于该下盖20，以使该上盖30与该下盖20间形成一容置空间320；一压缩弹簧40，设置于该容置空间320内，且定位于该弹簧容置槽24中：与一具有一凸出头部51的电热丝套组50，设置于该容置空间320内，且定位于该压缩弹簧40上，该电热丝套组50的凸出头部51申出于该上盖30的镂空窗31，当按压该电热丝套组50的凸出头部51时，该电热丝套组50可以相对该下盖20作动而接触导通。
其中该电热丝套组50包括：一热绝缘基部52、一电热线53、一第一金属扣合体54、与一第二金属扣合体55，在本例中该电热线53、该第一金属扣合体54及该一第二金属扣合体55是一体焊固结合而成。
请继续参阅图1及图2，本例的该电热丝套组50还包括有一耐热覆盖片56，其是为含有铁佛龙的网状边的物或者类似的材质制成，可提供一光滑的表面并保护电热模组，该耐热覆盖片56是覆盖于该电热线53之上，且该上盖还包括有一安全扣环32。
在本例中该下盖20的壳体23开设有一第一插合槽231与一第二插合槽232，该第一导电片21具有一插合部211可供插固于该第一插合槽231，该第二导电片22具有一插合部221可供插固于该第二插合槽232。
此外，该下盖20的壳体23具有一顶缘凹槽25，该上盖30具有一底部周围壁33，当该上盖30盖合该下盖20时，该下盖20的顶缘凹槽25可以由公差卡固于该上盖30的底部周围壁33。
请参阅图3，图3是本发明一较佳实施例的电热模组的作动图，如图所示，电热模组10的安全扣环32因设置于电热模组10的上方，如此，电热线53无法与电热模组10的第一导电片21与第二导电片22电接导通，可避免误触或按压而启动，使更加安全。
请参阅图4，图4是本发明一较佳实施例的电热模组的另一作动图，如图所示，当使用者于使用时须先将安全扣环32拨离电热模组10的上方，当电热丝套组50的凸出头部51下压时，电热线53与第一导电片21与第二导电片22电接导通。
请继续参阅图5，图5是本发明一较佳实施例的成品剖面图，如图所示，当热模组10组装于基座7的前容置室70时，第一导电片21的插合部211与第二导电片22的插合部221分别与电池室71中的二接点73，74接触导通，遂当按压部6下压电热丝套组50的凸出头部51时，电热线53经通以电流后温度升高，可以提供封合塑胶袋口的热能温度。
上述实施例仅是为了方便说明而举例而已，本发明所主张的权利范围白应以申请专利范围所述为准，而非仅限于上述实施例。
