为了实施活动门的正常使用以及防夹功能，时间继电器24的初始状态是：时间继电器24的线圈处于为失电状态，其常开开关26为打开 状态，其常闭开关28为闭合状态；防夹电磁铁15的初始状态为失电状态，防夹电磁铁15失电状态时，其防夹栓13为未伸出状态，防夹电磁铁15的第一线圈27未有电磁场发生，防夹栓13的左端面43未产生与固定磁铁40相同极性的磁极；定位电磁铁20的初始状态为得电状态，其锁栓18在定位电磁铁20磁力的作用下处于未伸出状态；防夹弹簧14以及定位弹簧19为压缩弹簧，防夹弹簧14的初始状态为未压缩状态，定位弹簧19的初始状态为被压缩状态，定位弹簧19对锁栓18的作用力方向是由锁栓18垂直指向防夹栓13；防夹栓13的轴线与定位孔16的轴线垂直，定位孔16的轴线与锁栓18的轴线平行；防夹弹簧14对防夹栓13的作用力方向是由防夹栓13被向固定磁铁40的外端面41。
智能自动家居门的使用方法是：使用时，当风吹活动门1快速关闭时，由于惯性的作用，活动门1上的惯性开关8导通，接通信号发射器7的电源，信号发射器7向信号接收器23发出保护信号，信号接收器23接收到其保护信号后，控制时间继电器24通电，时间继电器24的常开开关26闭合，常开开关26接通防夹电磁铁15的电源，防夹电磁铁15的第一线圈27有电源通过，使安装于第一线圈27内的防夹栓13产生磁场，使防夹栓13的左端面43产生与固定磁铁40相同极性的磁极，由于同性的磁极互相排斥，当防夹栓13的左端面43与固定磁铁40的外端面41接近时，防夹电磁铁15的电磁力与固定磁铁40磁力的相互排斥，减缓了活动门1关闭的速度；同时，防夹电磁铁15在磁力的作用下克服防夹弹簧14的弹力驱动防夹栓13向活动门1的边框22移动，当防夹栓13的定位孔16跟随防夹栓13移动；同时，时间继电器24的常闭开关28分断，切断定位电磁铁20电源，使定位电磁铁20对锁栓18的吸引力消失；当防夹栓13的定位孔16移动到锁栓18的位置时，锁栓18在定位弹簧19弹力的作用下插入定位孔16，利用锁栓18锁住防夹栓13，利用防夹栓13顶住活动门1的边框22，避免活动门1快速关闭，使活动门1与门框2留有间隔，防止活动门1夹伤小孩；活动门1被防夹栓13顶住后，时间继电器24的常闭开关28复位闭合，接通定位电磁铁20的电源，定位电磁铁20克服定位弹簧19弹力吸引锁栓18复位，使锁栓18离开定位孔16；锁栓18离开定位孔16后，时间继电器24的常开开关26分断，切断防夹电磁铁15的电源，防夹栓13在防夹弹簧14弹力的作用下复位，使活动门1与门框2处于能关闭的状态；同时，防夹电磁铁15的 第一线圈27的电磁场消失，防夹栓13失去磁性，防夹电磁铁15的磁极与固定磁铁40磁极的相互排斥力消除。
为了实施利用定位电磁栓11的锁栓18插入防夹电磁栓10的定位孔16，以及活动门1快速关闭时，不断增加阻碍活动门1关闭的阻力，定位电磁栓11的中心线与防夹电磁栓10的中心线垂直，定位电磁栓11的锁栓18的轴线与防夹电磁栓10的防夹栓13的轴线在同一平面上；防夹栓13的左端面43与固定磁铁40的外端面41的夹角为0°角至90°角，活动门1打开到位时，防夹栓13的左端面43与固定磁铁40的外端面41的夹角为90°角，活动门1关闭到位时，防夹栓13的左端面43与固定磁铁40的外端面41的夹角为0°角；防夹栓13的左端面43与固定磁铁40的外端面41的夹角为0°角时，防夹栓13的左端面43与固定磁铁40的外端面41平行，防夹栓13的左端面43与固定磁铁40的外端面41接触。
活动门1快速关闭时，固定磁铁40的外端面41与防夹栓13的左端面43的夹角不断减少，防夹栓13的左端面43与固定磁铁40的外端面41不断接近，防夹电磁铁15的磁极与固定磁铁40磁极的相互排斥力不断增加；防夹电磁栓10的防夹栓13移动时，防夹电磁栓10的防夹栓13移动的行程与定位孔16的轴线到定位电磁栓11锁栓18的轴线的距离相等。
为了实施对活动门1快速关闭的检测，为对活动门1快速关闭提供控制信号，惯性开关8为水银开关，水银开关的玻璃外壳36倾斜设置于信号发射器7的线路板上，水银开关内的水银38位于玻璃外壳36的底部，水银开关的电接点开关37位于水银38的上方；水银开关的玻璃外壳36与水平面的夹角为30°角至45°角；电接点开关37以及水银38在同一垂直面上。
为了实施减缓活动门1的快速摆动以及利用防夹栓13顶住活动门1，防夹栓13包括有固定栓30、活动栓31以及活动弹簧32，固定栓30位于门框2内，固定栓30设有导向孔35，活动弹簧32位于导向孔35内，活动栓31与导向孔35动配合连接，活动弹簧32的一端与导向孔35的孔底接触，活动弹簧32的一端与活动栓31接触，固定栓30与防夹电磁铁15的第一活动铁芯33连接；门框2设有通孔39，活动栓31穿过通孔39；通孔39的轴线与防夹栓13的轴线相同，通孔39的直径大于防夹栓 13的直径；锁栓18的直径小于定位孔16的孔径。
为了避免活动栓31被卡在，保持活动栓31良好的伸缩性能，活动弹簧32为压缩弹簧，活动栓31被活动弹簧32顶住，活动栓31处于伸出状态；活动栓31的左头端42的表面为弧面，以保证活动栓31与固定磁铁40的外端面41的弹性接触；为了避免活动栓31以及固定栓30余留磁性，活动栓31以及固定栓30由软磁材料构成；
防夹电磁铁15的第一线圈27通电时，防夹栓13的固定栓30以及活动栓31产生与固定磁铁40的外端面41极性相同的电磁极性，活动栓31首先与定磁铁40的外端面41接近，利用活动栓31的电磁力与定磁铁40的磁力的相互排斥作用克服活动弹簧32的弹力，驱动活动栓31向右移动，利用活动栓31的电磁力、定磁铁40的磁力以及活动弹簧32的弹力减缓活动门1关闭的速度；防夹电磁铁15的活动栓31向右移动时，防夹电磁铁15的第一线圈27通电，活动栓31产生与定磁铁40磁极相同的磁极，活动栓31的电磁极与定磁铁40的磁极产生互相排斥的作用力，阻碍活动门1快速关闭；活动门1停止后，防夹电磁铁15的第一线圈27失电，活动栓31磁性消失，活动栓31的电磁极与定磁铁40的磁极产生互相排斥的作用力消除，活动门1复位到正常使用状态。
活动门1快速关闭时，由于惯性的作用，水银开关内的水银38沿玻璃外壳36的内壁向上移动与电接点开关37接触，接通电接点开关37，水银开关的电接点开关37接通信号接收器23电源，使信号接收器23向信号接收器23发出保护信号。
信号接收器23向信号接收器23发出保护信号后，水银开关内的水银38流回到玻璃外壳36的底部，信号接收器23的电源被切断；活动门1停止摆动后，信号接收器23切断时间继电器24线圈的电源，时间继电器24的常闭开关28延时闭合，接通定位电磁铁20的电源，定位电磁铁20克服定位弹簧19弹力吸引锁栓18复位，使锁栓18离开定位孔16；锁栓18离开定位孔16后，时间继电器24的常开开关26延时分断，切断防夹电磁铁15的电源，防夹栓13在防夹弹簧14弹力的作用下复位；信号发射装置3、信号接收装置4以及防夹装置5恢复到初始状态。
为了实施锁栓18离开定位孔16后，防夹栓13再复位，时间继电器24的常闭开关28复位延时的瞬间小于时间继电器24的常闭开关28复位延时的时间，使锁栓18离开定位孔16后，防夹栓13再复位；防夹 电磁栓10复位时，锁栓18先在定位电磁栓11磁力的作用下克服定位弹簧19弹力向上移动，离开防夹栓13的定位孔16，锁栓18离开定位孔16后，防夹栓13在防夹弹簧14弹力的作用下向右移动，使防夹栓13的固定栓30移动到门框2内。
活动门1快速关闭时，防夹电磁铁15驱动其防夹栓13伸出，防夹栓13的活动栓31首先与活动门1的边框22接触，活动门1驱动活动栓31克服防夹栓13的活动弹簧32的弹力向固定栓30的导向孔35的孔底移动，利用活动弹簧32的弹力来阻碍活动门1摆动，减缓活动门1摆动的速度；防夹栓13的活动栓31与活动门1的边框22接触后，活动门1驱动防夹栓13的活动栓31移动到固定栓30的导向孔35的孔底时，活动门1被防夹栓13挡住不能再向关闭方向摆动，有效地防止活动门1快速关闭夹伤小孩。
