2. PREAMBLE TO THE DESCRIPTION

The following specification particularly describes the invention and the manner in which it is to be performed.

Title: New technology water electronic filter.

Description:

BACKGROUND OF THE PRESENT INVENTION

The present invention generally relates to a water filter system, and more specifically, to a water filter system that includes a filter unit that includes keyed features for interfacing with engagement features on a filter head assembly.

SUMMARY OF THE INVENTION

In an aspect of the present disclosure, a water filter unit includes a body portion, a first engagement surface that traverses at least part of the body portion, and a second engagement surface that traverses at least part of the body portion opposite the first engagement surface. An engagement protrusion extends from the body portion and has a water inlet and a water outlet. A curved engagement surface is disposed on the engagement protrusion proximate the water outlet. A first seal is disposed on the engagement protrusion. A first cross-section of the engagement protrusion, taken at the first seal and perpendicular to a longitudinal extent of the body portion, has only one axis of symmetry. A second seal is disposed on the engagement protrusion and is spaced apart from the first seal. The water inlet is positioned between the first and second seals.

These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art upon studying the following specification, claims, and appended drawings.

DETAILED DESCRIPTION OF EMBODIMENTS

For purposes of description herein the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention. However, it is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

A water filter system including a filter unit having a body portion having 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 14 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 having 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.

The body portion of the filter unit includes a cylinder-like construction having a diameter that is easily graspable by the hand of a user. A multitude of grasping cutouts are disposed on the body portion and extend toward the distal end of the body portion and are designed to provide a gripping surface for a user to both engage and disengage the filter unit from the filter head assembly. As disclosed in further detail herein, engagement of the filter unit typically includes rotational and longitudinal movement of the filter unit relative to the filter head assembly. An internal portion of the filter unit includes a water filter having a filtering media designed to filter and clean water that passes through the filter unit during use. The filtering media includes end caps that secure the filtering media in place in the body portion of the filter unit. The end cap includes an outlet that relays filtered water out of the filtering media after the water has been filtered. Seals prevent cross-contamination of unfiltered water with filtered water that has passed through the filtering media. The distance A from a distal protrusion surface of the filter unit to a first seal is approximately 2.69 millimeters. The first seal and a second seal have a thickness B of approximately 2.62 millimeters. The distance C between the distal protrusion surface and the second seal is approximately 18.69 millimeters, while the distance D from the distal protrusion surface to a shoulder support is approximately 28.30 millimeters. Finally, the distance E from the distal protrusion surface to the laterally extending key member is approximately 41.20 millimeters. The dimensions noted above are specifically configured to complement and interact with the filter head assembly, thereby allowing for tight and secure engagement of the filter unit with the filter head assembly.
, C , C , Claims: CLAIMS

We claim:

1) A water filter unit comprising: a body portion;
a first engagement surface traversing at least part of the body portion; a second engagement surface traversing at least part of the body portion opposite the first engagement surface; an engagement protrusion extending from the body portion and having a water inlet and a water outlet; a curved engagement surface disposed on the engagement protrusion proximate the water outlet; a first seal disposed on the engagement protrusion, wherein a first cross-section of the engagement protrusion, taken at the first seal and perpendicular to a longitudinal extent of the body portion, has only one axis of symmetry; and a second seal disposed on the engagement protrusion and spaced apart from the first seal, wherein the water inlet is positioned between the first and second seals.
