当所述显示板20启动时，所述驱动芯片U的使能端STB获得使能信号启动，所述驱动芯片U的数据端DIO通过所述第二连接器获得所述电源板10输入的所述第一控制信号，所述驱动芯片U根据所述第一控制信号在其驱动端和输出端输出相应的驱动信号至所述第一数码管2301、第二数码管2302、第三数码管2303和第四数码管2304，以使其显示相应的数据。其中，所述第一电阻R1、所述第二电阻R2及所述第三电阻R3分别用于限制流入所述驱动芯片U的数据端DIO、时钟端CLK及使能端STB的电流大小，从而防止驱动芯片U因输入其引脚的电流过大而烧坏。所述第一电容C1、所述第二电容C2及所述第三电容C3则均用于滤波。值得一提的是，由于所述驱动芯片U具有多个输出端及驱动端，所以，所述显示模块230还可以采用LCD显示屏。此外，由于所述驱动芯片U还有数个闲置的驱动端和输出端，因此，所述显示模块230除了包括所述数码管外，还可以增设指示灯等进一步加强显示的电路结构。此外，采用该种电路结构，可以节省驱动芯片U的接口资源。
需要指出，可以将所述第一连接器1400的接线端制成插孔，将所述第二连接器的接线端制成与所述插孔相对应的针脚，使所述显示板20与上述的电源板10插接连接。当用户需要更换显示板20时，只需将插接在所述电源板10上的旧显示板拔出，插上新的显示板。由于只要待更换的显示板20的第二连接器2300的接线端与电源板10的第一连接器1400的接线端相匹配，就可以不用更换任何其它的硬件设备实现新旧显示板的更换。因此，相对于现有技术，本发明技术方案具有节省成本，操作简便的特点。当然，也可以用跳线连接所述第一连接器1400的接线端与所述第二连接器2300的接线端，以方便更换所述显示板20放置的位置。
值得一提的是，本实施例中，所述第一连接器1400的第一接线端与所述第二连接器2300的第六接线端连接；所述第一连接器1400的第二接线端与所述第二连接器2300的第五接线端连接；所述第一连接器1400的第三接线端与所述第二连接器2300的第四接线端连接；所述第一连接器1400的第四接线端与所述第二连接器2300的第三接线端连接；所述第一连接器1400的第五接线端与所述第二连接器2300的第二接线端连接；所述第一连接器1400的第六接线端与所述第二连接器2300的第一接线端连接。
优选地，如图8至图9所示，所述显示板20具有显示板正面201和显示板背面202；所述显示板正面201设有数据显示单元2011、状态显示单元2012、至少两个螺钉孔2013及所述第二连接器2300。其中，所述数据显示单元2011为如上所述的数码管；所述状态显示2012单元包括多个LED灯，多个个所述LED灯可以用于指示所述电加热装置的工作状态，也可以用于指示所述数码管的工作状态，此处不做限制。其中，LED灯的数量也不限定，例如如图8所示的十个LED灯。所述螺钉孔2013用于与螺钉适配，以固定所述显示板20。所述第二连接器2300的针脚的裸露部分面向所述显示板背面202。在组装所述电加热装置时，只需将所述第二连接器2300的针脚的裸露部分对应插进所述第一连接器1400的插孔，并用螺钉（图未示出）将所述显示板20固定，不仅操作简便，还便于所述显示板20的批量的生产，从而提高电加热装置的生产效率。
如图10所示，本发明还公开一种电加热装置的组装方法，该方法包括以下步骤：
步骤S10：控制第一传输机构将已成型的电源板运输至程序测试机台；
步骤S20：控制程序测试机台的第一定位机构将所述电源板与程序测试机台的程序烧录接口进行对位并插接，以测试所述电源板是否合格；
步骤S30：控制第一夹持机构将测试合格的电源板传递至第二传输机构上；
步骤S40：控制所述第二传输机构将所述电源板传输至组装机台，并控制组装机台的第二定位机构将所述电源板的第一通讯结构与预置于该组装机台上的显示板的第二通讯接口进行对位并插接，组装完成；其中，显示板已预装于电加热装置的壳体组件上。
需要说明的是，可以在所述电源板10与所述显示板20组装成型之前向所述电源板10烧录程序，也可以在所述电源板10与所述显示板20组装成型之后向所述电源板10烧录程序，此处不做限制。
值得一提的是，现有的电加热装置生产工厂在生产所述电加热装置时，一方面，需要针对每一特定的电加热装置的显示板20的型号逐个向所述电加热装置烧录程序，不利于所述电加热装置的大规模生产。另一方面，工厂工作人员需要时刻应对向具有不同显示板20的电机热装置烧录程序，会降低工厂工作人员的工作效率。
而本发明技术方案中，由于对所述电加热装置中的电源板10及显示板20进行了模块化处理，在将所述电源板10及所述显示板20组装成所述电加热装置时，只需将所述电源板10中第一连接器1400中的针脚插进所述显示板20中第二连接器2300中的插孔。因此，本电加热装置组装方法提高了所述电加热装置的生产效率，实现了所述电加热装置的批量生产。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
