<p>The invention relates to a connection structure of a filter cartridge for a water purifier. The structure comprises an inner case in which a first opening/closing valve and a second opening/closing valve are moved by a predetermined distance, wherein the first opening/closing valve is optionally connected to an inlet hole of a filter cartridge and the second opening/closing valve is optionally connected to an outlet hole of the filter; an outer case disposed to surround the inner case in order to move the first opening/closing valve and the second opening/closing valve so that the inlet hole can be disconnected to the first opening/closing valve and the outlet can be disconnected to the second opening/closing valve; a bias member arranged between the outer case and the inner case so that the outer case can be separated from the inner case; and a coupling/guiding member coupling the outer case with the inner case, guiding movement of the outer case for the inner case, and including at least one coupling/guiding hole formed in the inner case and a coupling/guiding protrusion formed in the outer case to be corresponded to the coupling/guiding hole, wherein the inner case and the outer case can be coupled to each other in a one-touch manner by using the coupling/guiding member thereby improving productivity since time for necessary for assembly work of the inner case and outer case can be reduced.</p> |
