摘要： 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.

摘要： 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.

摘要： A filter unit includes a body portion and an engagement protrusion that extends from the body portion with a first water containment seal. At least one cross-section of the engagement protrusion at a location of the first water containment seal, taken perpendicular to a central longitudinal axis of the body portion, includes an egg-shaped outer perimeter with a single axis of symmetry. At least one engagement surface traverses around at least part of the body portion. The at least one engagement surface has a linear movement section for linear movement of the body portion. The linear movement section transitions to a rotational movement section for rotational movement of the body portion. The rotational movement section is angled relative to the linear movement section. A water inlet path and a water outlet path extend through a portion of the engagement protrusion defined by the at least one cross-section.
