Multifunctional Check Valve Device

摘要

A multifunctional check valve device contains: a base, an elastic member, and a locking member. The base includes a peripheral rib, an accommodating chamber, a column, a stopping face, a connecting orifice, a plurality of through orifices, a first outlet, and a positioning groove. The elastic member includes a fixing loop for retaining with the connecting orifice and a closing disc for corresponding to a second outlet of a pull-out faucet. An outer diameter of the closing disc is greater than an inner diameter of the closing disc, so the closing disc closes an inner face of an exit. The closing disc has a retaining tab for retaining with the positioning groove. The hollow locking member includes inner threads for screwing with outer threads of the pull-out faucet and accommodates the base. The hollow locking member also includes a third outlet for aligning with the first outlet of the base.

1. A multifunctional check valve device being mounted on an exit of a faucet and comprising: a base, an elastic member, and a locking member; wherein
the base includes a peripheral rib arranged around a top end thereof, an accommodating chamber defined therein, a column extending outwardly from a central position of the accommodating chamber, a stopping face formed on a top end of the column, a connecting orifice defined on a central position of the stopping face, a plurality of through orifices equidistantly defined around an outer wall of the column, a first outlet formed on a bottom end of the column, and a positioning groove formed on a lower side of the outer wall of the column; the elastic member is made of deformable material and includes a fixing loop extending outwardly around a bottom end thereof to correspond to the column, wherein the fixing loop is fitted with the column of the base; the elastic member also includes a fitting segment extending downwardly from a central position of a bottom end thereof to correspond to the connecting orifice; the elastic member further includes a closing disc formed on a top end thereof and corresponding to an exit of a faucet, wherein an outer diameter of the closing disc is greater than an inner diameter of the closing disc, such that the closing disc of the elastic member closes an inner face of the exit; the closing disc has a retaining tab arranged around a peripheral side thereof and retaining with the positioning groove of the column of the base to reduce half of water flow from the plurality of through orifices; a hollow locking member includes inner threads defined around an upper side of an inner wall thereof to screw with outer threads of the faucet, and the base is accommodated inside a lower side of the inner wall of the hollow locking member, the hollow locking member also includes a third outlet defined on a central position of a bottom end thereof and aligning with the first outlet of the base.
