Abstract: A filter unit includes a body portion having a proximal end and a distal end. An engagement protrusion extends from the proximal end. The engagement protrusion includes a first portion that has a first radius of curvature and a second portion opposing the first portion that has a second radius of curvature that is larger than the first radius of curvature. A protruding retention surface is disposed on and extends radially outward from the body portion. The protruding retention surface is adapted to secure the filter unit in a filter head assembly.

Abstract: A water filter system includes a removable filter unit having a body portion including a proximal end and a distal end. The proximal end is adapted to be inserted into a filter head assembly. A laterally extending key member is disposed on the body portion and adapted to engage a key slot in the filter head assembly. An engagement protrusion extends from the proximal end. The engagement protrusion includes a first portion that has a first radius of curvature and a second portion opposing the first portion that includes a second radius of curvature that is larger than the first radius of curvature.

Abstract: A water filter includes a filter unit having a body portion adapted to be rotatingly received into a filter head assembly. An engagement protrusion extends from the body portion and is adapted for reception in a complementary receiver in the filter head assembly. An electronic device is disposed on the filter unit having a memory storage unit. A laterally extending key member is disposed on the body portion between the first engagement surface and the second engagement surface. The laterally extending key member is adapted to reposition an interference member from an interference position, whereby the body portion can be fully inserted into the filter head assembly to a non-interference position, whereby the body portion can be fully inserted into the filter head assembly.

Abstract translation: 水过滤器包括具有主体部分的过滤器单元，该主体部分适于旋转地容纳在过滤器头组件中。 接合突起从主体部分延伸并且适于在过滤器头组件中的互补接收器中接收。 电子设备设置在具有存储器存储单元的过滤器单元上。 横向延伸的键构件设置在第一接合表面和第二接合表面之间的主体部分上。 横向延伸的键构件适于将干涉构件从干涉位置重新定位，由此主体部分可以完全插入到过滤头组件中到非干涉位置，由此主体部分可以完全插入过滤头组件 。
