如图 5所示， 顶渣机构 12包括顶渣杆 12 1、 弹簧 122、 弹簧挡圈 123 和分水盘组件， 分水盘组件设置在顶渣杆 121上端， 顶渣杆 121上设有用 于限位的限位凸台 126 , 弹簧挡圏 123设置在限位凸台处 126 , 弹簧 122 设置在分水盘组件与弹簧挡圈 123之间， 分水盘组件包括第一分水盘 124 和第二分水盘 125 , 第一分水盘 124设置在第二分水盘 125上。 顶渣机构 12上的弹簧 122， 在冲煮头 21向下进行压咖啡粉 1 0的动作时， 顶渣机构 12上的弹簧 122会压缩。 而当冲煮头 21向上做轻微位移时，弹簧 122会对 顶渣机构 12施加推力而将咖啡粉 10向上顶。
如图 5所示， 复位机构 13包括复位杆 131、 复位杆转轴 132、 复位杆 驱动臂 133和复位圓柱 134 , 复位杆转轴 132设置在复位杆 131上， 复位 杆驱动臂 133设置在复位杆转轴 1 32两端，复位圆柱 134设置在复位杆 131 的一端。

如图 10所示， 还包括复位架 5 , 复位架 5设置在主体支架 4下端， 复 位架 5上设有限位凸台 51 , 限位凸台 51与复位圆柱 134相匹配。 在冲泡 机构 2完成咖啡冲泡动作之后， 驱动件 22带动冲煮头 21向上运动， 在沖 煮头 21脱离咖啡渣时，顶渣机构 12因自身的弹力把咖啡渣向上顶松，通过 驱动件 22带动复位机构 13， 实现推动顶渣机构 12的动作， 复位机构 13 通过与复位架 5的限位凸台 51相作用实现向下拉动顶渣机构 13复位。
如图 1所示， 主体支架 4两侧还设置有外盖 6 , 将驱动件 22固定在主 体支架 4内。
本发明的沖泡装置的工作过程说明如下：
如图 11所示， 咖啡粉 10由主体支架 4的咖啡粉进入孔 41加入，加入 咖啡盒 1 1 内， 外部传动机构 9带动大齿轮 23转动， 大齿轮 23的内螺纹 231与主体支架 4上传动部件 42的外螺纹 421相匹配， 由于两个零件的螺 纹传动， 可以使得大齿轮 23在主体支架 4上进行上下移动。 冲泡机构 2 包括外形大致为圆柱形的冲煮头 21 , 冲煮头 21 的外侧壁上设置有连接座 21 1 ,驱动件 11朝向沖煮头 21的内侧壁上设置有形状与连接座 211相对应 的连接头 225 , 驱动件 22与冲煮头 21通过连接头 225与连接座 21 1的结 合而连接在一起。体支架 4上设置有能够与大齿轮 2 3的内螺紋 231相配合 传动的外螺纹 4 Π , 大齿轮 23在传动部件 42上， 通过传动部件 42的外螺 纹 421进行转动， 实现沿传动部件 42轴线方向的位置改变，从而冲泡机构 2发生位置改变。 当大齿轮 23顺时针转动的同时大齿轮 23的下端面与沖 煮头 21连接座 21 1 的上端面接触产生一个向下的推力， 从而带动冲煮头 21向下移动。 在大齿轮 23做上下运动的同时， 驱动件 22和冲煮头 21也 可以一同进行上下运动。 外盖 6安装在主体支架 4的两侧， 用来防止驱动 件 22偏离运动轨道。
主体支架 4的外部轮廓与咖啡盒 1 1的形状相对应，组装状态下， 第一 圆柱 11 1安装设置在第一装配孔 43内，第二圓柱 1 12活动设置第二运动导 槽 44内，第二运动导槽 44的弧状是以第一装配孔 43为圆心的一个预定圆 心角，本实施例中圆心角为 30度。 因此咖啡盒机构 1可以利用其下端的左 右两个第一圆柱 1 1 1为转轴， 其上端的两个第二圓柱 1 12在主体支架 4上 的第二运动导槽 44内进行 30度角范围内的往复滑动。
驱动件 22上设有用于驱动咖啡盒机构 1的驱动槽 221 , 驱动槽 221与 第一圆柱 11 1相匹配， 驱动槽 221包括直线驱动槽 222和弧形驱动槽 223; 驱动件 22下端还设有用于实现顶渣机构 U复位的复位凸轮 224。 驱动件 22通过驱动槽 221对咖啡盒机构 1产生驱动作用， 过程中， 第二圆柱 112 穿过第二运动导槽 44并设置在驱动槽 221内以实现驱动力的传递。同时带 动咖啡盒机构 1进行 30度的左右摆动。
如图 12所示， 当咖啡盒机构 1上端的两个第二圆柱 112在驱动件 22 的驱动槽 221内， 从直线驱动槽 222滑动到弧形驱动槽 时， 咖啡盒机 构 1逆时针转动， 从弧形驱动槽 223滑动到直线驱动槽 222时， 咖啡盒机 构 1顺时针转动。 大齿轮 23带动冲泡机构 2继续向下运动， 当咖啡盒 11 上端的第二圆柱 112位于直线驱动槽 222时， 咖啡盒机构 1停止转动而保 持与冲煮头 21在同一轴线上，在咖啡盒 11处于与冲煮头 21同一轴线的同 时， 沖煮头 21继续下压， 此时第一分水盘 124受力带动顶渣杆 121—起向 下移动， 而顶渣杆 121上的弹簧挡圏 123被顶渣杆 121的限位凸台 126挡 住， 弹簧 122受力压缩， 直到第二分水盘 125的下端面与咖啡盒 11的底面 接触， 此时沖煮头 21将咖啡盒 11内部的咖啡粉 10压实。
在压实后， 步进电机 33向上直线运动拉动活塞式的进水开关 32向上 移动， 使进水开关 32从初始泄水状态脱离 Y型密封圏 35的位置， 使进水 开关 32的主轴部分与 Y型密封圏密封 35密封， 这时进水煮咖啡时， 热水 进泄水机构主体 31后，直接通过咖啡盒机构 1上的咖啡盒进水孔 8进入咖 啡盒 11与第二分水盘 125之间的腔体内，经过第一分水盘 124与第二分水 盘 125的分水孔均勾的分流入咖啡粉 10进亍咖啡萃取动作，然后咖啡由冲 煮头 21上的咖啡出口到咖啡出水接头 27流出。咖啡出水接头 27与沖煮头 21之间安装有出口接头密封圈防止咖啡溢出。
顶渣杆 121与咖啡盒 11之间靠顶渣杆密封圏密封， 煮咖啡的时候，咖 啡不会从咖啡盒 11下端流出。冲煮头 21与咖啡盒 11之间靠冲煮头密封圏 密封， 咖啡不会从沖煮头 21周围漏出， 过滤网 25通过过滤网螺丝 26锁附 在冲煮头 21上， 防止煮咖啡的时候， 咖啡粉 10跑出来。
如图 13所示， 煮完咖啡后， 驱动步进电机 33向下做线性运动， 推动 进水开关 32向下移动，使进水开关 32上的开关槽处于 Y型密封圏 35的位 置， 使密封圏失去密封效果， 进一步的使咖啡盒 11 内的水直接由泄水口 312泄出。
如图 14所示， 沖煮头 21左右两侧驱动件 22下方各有一个复位凸轮 224 , 此突起部位上方为平面， 下方为斜面， 在驱动件 22向上移动时， 冲 煮头 21对咖啡粉 10施加的力消失， 此时顶渣杆弹簧 122 自身的弹力将顶 渣杆 121向上推动， 使被冲煮头 21压的很紧的咖啡渣 10变松， 弹簧的推 动空间是 6mm，在驱动件 22驱动复位杆 131开始顶咖啡渣之前， 弹簧 122 就提前把咖啡盒 11 内的咖啡渣向上顶了 6隱，此时冲煮头 21 继续向上移 动， 直到冲煮头 21左右两侧驱动件 22的复位凸轮 224上的突起部位上端 面与复位杆 131左右两侧的复位驱动臂 133接触， 从而带动复位杆 131以 复位杆转轴 132为圆心绕咖啡盒 11上的配合孔 11 3转动。
如图 14所示， 当咖啡盒 11上端的第二圓柱 112在冲煮头 21驱动件 22上驱动槽 221的直线驱动槽 222内滑动时， 咖啡盒机构 1不转动， 同时 驱动件 22下方的复位凸轮 224与复位杆 131左右两侧复位驱动臂 133的下 端面接触， 使复位杆 131顺时针转动， 复位杆 131转动的同时通过驱动圓 135给顶渣杆 121的驱动孔 127的施加推力带动顶渣杆 121向上运动。 当 咖啡盒 11上端的第二圆柱 112滑动到沖驱动件 22上驱动槽 221的弧形驱 动槽 223， 整个咖啡渣已被顶出咖啡盒 11的腔体。
如图 15所示， 此时咖啡盒机构 1开始逆时针转动， 转动的同时， 咖啡 渣被主体支架 4上的外螺纹 421的内侧端面挡住，此时驱动件 22下方的复 位凸轮 224与复位杆 1 31左右两侧复位驱动臂 133的下端面分离， 驱动件 22继续向上移动， 此时咖啡盒机构 1继续逆时针转动， 顶渣机构 12上的 咖啡渣被刮掉。
如图 16所示， 咖啡盒机构 1转动的同时， 复位杆 131的复位圆柱 134 的外表面与复位架 5上端的限位凸台 51的上端面接触， 当驱动件 22继续 向上移动带动咖啡盒机构 1逆时针转动的同时，复位杆 131 下端复位圓柱 134的外表面被复位架 5上端的限位凸台 51 的上端面挡住，使复位杆 131 以复位杆转轴 132为圓心绕咖啡盒 11上的配合孔 11 3逆时针转动，此时复 位杆 131的驱动圓 135给顶渣杆 121的驱动孔 127下端面施加向下的推力， 拉动顶渣杆 121向下运动，驱动件 22继续向上移动带动咖啡盒机构 1逆时 针转动到 30度角时， 咖啡盒机构 1 回复到加咖啡粉的状态， 此时复位杆 131带动顶渣杆 121回复到原始位置， 此时整个煮咖啡过程完成。
采用本: |支术方案的有益效杲是： 传动控制精确， 进水结构简单， 噪音 低， 工作周期短， 性能稳定， 免拆卸清洗， 使用寿命长， 性能更可靠， 机 械零件少。
对所公开的实施例的上述说明， 使本领域专业技术人员能够实现或使 用本发明。 对这些实施例的多种修改对本领域的专业技术人员来说将是显 而易见的， 本文中所定义的一般原理可以在不脱离本发明的精神或范围的 情况下， 在其它实施例中实现。 因此， 本发明将不会被限制于本文所示的 这些实施例， 而是要符合与本文所公开的原理和新颖特点相一致的最宽的 范围。
