如图 7A所示, 分水端盖 10包括进水通道 101和出水通道 102, 分别 与卡座 3上的进水口 301和出水口 302相配合(如图 2及图 6A所示;); 进 水通道 101和出水通道 102相互独立不连通; 如图 7B所示, 分水端盖 10 包括第三凸块 108 , 卡扣 9包括与第三凸块 108相配合的第三凹槽 98 (未 在图中示出), 第三凸块 108卡在第三凹槽 98内, 用来阻止分水端盖 10在 转动时与卡扣 9产生相对转动; 如图 3所示, 分水端盖 10顶部设有密封圈 36; 卡扣 9套紧在简体 11上, 在转动过程中卡扣 9与简体 11不发生相对 转动。
当处于封水状态时,第一通孔 55和第二通孔 56不连通;进水通道 101 与进水口 301不连通, 出水通道 102与出水口 302不连通;
当处于打开状态时, 第一通孔 55和第二通孔 56连通; 进水通道 101 与进水口 301连通, 出水通道 102与出水口 302连通。
如图 7B所示, 分水端盖 10在与滤芯 20的相接触的一面设置有波浪 式条紋, 以增大粘接表面积, 进而加强分水端盖 10与滤芯 20之间的牢固 性。
本发明的工作原理如下:
滤芯上盖 1和滤简 2分离时, 处于封水状态;
在滤简 2内安装好滤芯 20后,将滤芯上盖 1和滤简 2旋转扣合,同时, 滤芯上盖 1内部的转轴 7在滤简 2的带动下发生转动;滤简 2旋转 90度后 转轴同步旋转 90度,此时陶瓷下片 6在转轴 7的带动下也相对于陶瓷上片 5转动 90度, 第一通孔 55、 第二通孔 56、 第三通孔 76相连通, 处于打开 状态; 如图 7A所示, 外部水源通过进水口 301进入滤芯上盖 1 , 依次经过 通孔 56、 通孔 76、 分水端盖 10上的进水通道 101 (箭头 a方向), 从滤芯 20外部进入滤芯 20内部进行过滤(箭头 b方向); 过滤后的水流从滤芯 20 内部再经过分水端盖 10上的出水通道 102 (箭头 c方向)、 卡座 3上的出 水口 302流出 (箭头 d方向 )。
需要维修或者更换滤芯时, 反向旋转滤简 2, 内部陶瓷上片 5和陶瓷 下片 6相对旋转 90度, 第一通孔 55和第一通孔 56不连通而封闭水流, 同 时滤简 2旋转 90度后与滤芯上盖 1分离, 即可进行维修或者更换。
本发明结构简单, 省去了繁杂的支路构件和弹簧装置, 拆装方便; 防 震动、 防旋转过当; 进水通道和出水通道相互独立, 防止二次污染。
以上所述仅为本发明的优选实施方式, 应当指出, 对于本技术领域的 普通技术人员来说, 在不脱离本发明技术原理的前提下, 还可以做出若干 改进和润饰, 这些改进和润饰也应视为本发明的保护范围。
