A key startup module

The utility model provides a key startup module. It is including heating module, control module and motor circuit, and motor circuit includes motor MG1 and independent switch, and control module includes voltage conversion module and relay, and the heating module is connected with the input of voltage conversion circuit, and the output of voltage conversion circuit passes through for relay power supply, heating module the normally open contact of relay inserts motor circuit. This a key startup module starts the back at the heating function and starts the heat dissipation motor simultaneously,can prevent to forget when using the heating function and open cooling fan and lead to the condition that plastic part warp or the heating module is damaged, and motor circuit also can independently open, uses in a flexible way. 种键启动模块。它包括加热模块、控制模块和电机电路，电机电路包括电机MG1和独立开关，控制模块包括电压转换模块和继电器，加热模块与电压转换电路的输入端连接，电压转换电路的输出端为继电器供电，加热模块通过所述继电器的常开触头接入电机电路。本键启动模块在加热功能启动后同时启动散热电机，可防止出现使用加热功能时忘记将散热风机打开而导致塑料部件变形或加热模块损坏的情况，且电机电路也可独立开启，使用灵
