Water Filter Assembly

摘要

In the water filter assembly, the flow path could be changed to the bypass flow path or the purified water flow path, when the inner moves upwardly and downwardly in the filter head by combining or separating of the filter body and filter head. The inner is movably inserted to the filter head. The elastic member changes the flow path to bypass flow path when the filter body is separated by elastic biasing the inner between the filter head and the inner to downward direction of the filter head. If the user pushes the inner to the inside of the filter head by mistake when the filter body is separated from the filter head, the inner is pushed out to be the original position, so that the filter body can be rapidly combined to the filter head including the inner.

主权项

1. A water filter assembly comprising:
a filter head including an inlet formed at one side, an outlet formed opposite to the inlet, the inlet and the outlet each communicating with a hollow area formed inside the filter head, and a head key guide formed in an inside face of the hollow area; an inner including a bypass flow path formed at an upper end, a purified water flow path formed adjacent to the bypass flow path, and an inner key guide formed in an inside face of the inner, the inner being inserted to the hollow area of the filter head to move upwardly and downwardly; a filter body to connect a water flow path to the purified water flow path by moving the inner upwardly within the hollow area when the filter body is engaged with the filter head having the inserted inner and to connect the water flow path to the bypass flow path by moving the inner downwardly within the hollow area when the filter body is disengaged from the filter head having the inserted inner, the filter body including an inner key for detachably coupling to the inner key guide at an upper part of the filter body and a head key for detachably coupling to the head key guide at a lower part of the filter body; and an elastic member being positioned between the filter head and the inner, to bias the inner downwardly with respect to the filter head.
