Claim:
A detachable rotational filter supporter comprising: a housing ( 10 ) with a receiving hole ( 11 ) in which a neck ( 91 ) of a filter ( 90 ) is placed; an inflow part ( 20 ) whose inlet is formed at one side of the housing ( 10 ) and whose outlet is formed to communicate with the receiving hole ( 11 ), wherein the inflow part ( 20 ) includes a narrow portion ( 21 ) of a flow channel at one side of the inflow part ( 20 ), so that the inlet has a larger diameter than the outlet; an outflow part ( 30 ) whose outlet is formed at another side of the housing 10 and whose inlet is communicate with the receiving hole ( 11 ); a base ( 40 ) installed to the housing ( 10 ) in such a way to form a receiving space ( 14 ) in the lower portion of the housing ( 10 ), wherein the base ( 40 ) forms a through-hole ( 41 ) whose axis is the same as the receiving hole ( 11 ); a pair of hinges ( 50 ) each of which includes a flow-hole ( 51 ) therein, wherein the pair of hinges ( 50 ) are fixed to a inner wall of a water purifier, and inserted into the inlet of the inflow part ( 20 ) and the outlet of the outflow part ( 30 ) so that the inflow part ( 20 ) and the outflow part ( 30 ) can communicate with each other through their flow-holes, in which the pair of hinges ( 50 ) are rotatable with respect to the axis established by the inflow part ( 20 ) and the outflow part ( 30 ); a pair of locking parts ( 60 ) slidably installed to the receiving space ( 14 ), each of which forms: an arc portion on a facing side and an thin plate ( 62 ) at the opposite side of the facing side, which is protrudent to the opposite outside of the housing ( 10 ); at least two or more compression springs ( 70 ) installed between the pair of locking parts ( 60 ) for pushing the pair of locking parts ( 60 ) to the outside; a protrusion ( 75 ) protrudently formed from each hinge ( 50 ) so that the protrusion ( 75 ) can contact the thin plate ( 62 ) of the locking part ( 60 ), wherein the protrusion ( 75 ) assists the arc portion ( 61 ) to contact the neck ( 91 ) of the filter ( 90 ) and to hole the filter ( 90 ) when the protrusion ( 75 ) contacts the thin plate ( 62 ); and a check valve ( 80 ) installed to one side of the inflow part ( 20 ) for opening or closing the flow channel of the inflow part ( 20 ) when the filter ( 90 ) is installed to or separated from the water purifier.
