为使作用在冲泡头8上的作用力更平均，达到更好的使用效果，上述驱动轮14包括左凸轮14A、右凸轮14C, 左凸轮14A与右凸轮14C成一整体锁附在转轴9上，左凸轮14A与右凸轮14C的工作轮廓作用在冲泡头8的顶面两侧，冲泡头8上相应设有限定左凸轮14A及右凸轮14C的运动行程的肋骨8C。
此外，为确保冲泡头不会向一边翘起、确保密封性，上述左凸轮14A与右凸轮14C之间还设有与之成一整体，起到平衡作用的中间凸轮14B。上述包括有左凸轮14A、中间凸轮14B、右凸轮14C的三凸轮为一整体通过四个机制螺钉11装设在转轴9的中间。上述支架3的上部分别设有穿过转轴9的通孔。
为确保弹簧4的驱动力沿纵向方向作用在冲泡头8上，上述弹簧驱动结构还包括支架3上设有的套筒3A、冲泡头8上设有的柱子8A, 弹簧4的下端置于支架3上设有的套筒3A内，弹簧4的上端套装在冲泡头8上设有的柱子8A上。为确保作用在冲泡头8上的弹簧力均衡，上述支架3的两侧分别设有套筒3A ，冲泡头8的两侧也相应分别设有柱子8A，两弹簧4的下端及上端分别置于支架3两侧的套筒3A及柱子8A上。
为确保冲泡头8的上下运动顺畅自如，上述支架3的上部还设有使冲泡头8在其上运动的导向套筒3B，冲泡头8上相应设有与之配合的导向孔。

本发明的工作原理如下：通过旋转手柄12，从而带动转轴9再驱动锁附在转轴上的驱动轮14旋转。手柄12逆时针旋转时，通过弹簧4伸张驱动冲泡头8向上做直线运动；手柄12顺时针旋转时，通过驱动轮14旋转驱动冲泡头8向下做直线运动，从而使酿造腔达到打开与封闭状态转换的目的。其具体动作如下：当转轴9顺时针旋转时，左凸轮14A、右凸轮14C驱动冲泡头8做向下直线运动，当左凸轮14A、右凸轮14C与冲泡头8的顶面成一定负角度， 中间凸轮14B也顶住冲泡头8的顶面时，左凸轮14A、右凸轮14C被冲泡头8上的肋骨8C挡死，冲泡器自锁，冲泡头8向下运动至咖啡漏斗1内，密封圈7将与咖啡漏斗1的内壁形成轴向密封，形成一个密封酿造腔体，即酿造腔呈封闭状态 。当转轴9逆时针旋转时，驱动轮14逆时针旋转，弹簧4伸张驱动冲泡头8向上做直线运动，当冲泡头8向上运动至密封圈7与咖啡漏斗1脱离时，密封酿造腔打开，达到酿造腔打开的目的，这时，驱动轮14随转轴9逆时针旋转处于水平状态，酿造腔呈打开状态，此时可放入或取出咖啡漏斗1。
本发明的使用过程如下：
第一步：清洗酿造器：将手柄12旋转至垂直状态，这时酿造器呈打开状态，如图5所示，然后将咖啡漏斗1稳妥推入支架3内，再将手柄12旋转至水平状态，这时酿造器呈关闭状态，如图4所示，开启电源按健，此时机器内的水泵将水箱内的水泵入发热煲，发热煲出水口通过水管将水注入酿造器冲泡头入水嘴8B，再通过咖啡漏斗1，水从咖啡漏斗1经冲泡嘴1A流入咖啡嘴2 流出，此时关闭电源按健，完成酿造器的清洗工作。
第二步：将手柄12旋转至垂直状态，这时酿造器呈打开状态，如图5所示，将咖啡漏斗1取出，然后将咖啡粉或咖啡包、咖啡胶囊装入咖啡漏斗1内, 再将咖啡漏斗1稳妥推入支架3内，最后将手柄12旋转至水平状态，这时，酿造器关闭状态，如图4所示。
第三步：酿造咖啡：开启电源按健，当机器预热完成后,按下煮咖啡控制按键，机器便能煮出香浓咖啡了。
第四步：酿造咖啡完成后再按下煮咖啡控制按键停止煮咖啡，将手柄（12）旋转至垂直状态，这时酿造器呈打开状态，如图5所示，再将咖啡漏斗1从支架3内取出，完成煮咖啡。
第五步：若想再次冲煮咖啡，可重复上述操作。
