Electronic interface for water filtration system

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.

1. A water filter comprising:
a body portion adapted to be rotatingly received into a filter head assembly; an engagement protrusion extending from the body portion and adapted for reception in a complementary receiver in the filter head assembly; an electronic device disposed on the filter having a memory storage unit; a protective cover of the electronic device having a generally triangular-type cross-section extending away from an outer circumference of the body portion to an apex of the triangular-type cross-section, wherein a plurality of exposed metallic contacts are disposed on a substantially planar surface of the protective cover, and wherein the memory storage unit is disposed within an interior volume defined by the protective cover; and a laterally extending key member disposed on the body portion between a first engagement surface and a second engagement surface, the laterally extending key member adapted to reposition an interference member in the filter head assembly from an interference position, whereby the body portion cannot be fully seated into the filter head assembly to a non-interference position, whereby the body portion can be fully seated into the filter head assembly.
