Patent ID: 6966335

Claim:
A valve core for a single handled faucet, comprising a valve housing, a valve stick, a base mount, a switching control valve, and a valve seat; the present invention being characterized by that, the valve housing, a two-staged sheltering case, having a valve chamber disposed at the interior thereof, a retaining block protruding at the inner top surface of the valve chamber thereof, and a plurality of insert grooves cut at the lower periphery thereof; the valve stick having a protruded connecting section extending downwards at the bottom thereof, and a two-staged valve stick seat with a turning protruded block extending downwards at one upper side joined at the middle section thereof; the base mount, a two-staged means, being equipped with a pivot hole disposed at the center thereof, a turning cut area defined at one upper side thereof, a retaining cavity cut at one lower side thereof, and a protruded guide spot disposed at the lower bottom surface thereof; the switching control valve having an indented recess cut at one side thereof, and a receiving hole communicating with the indented recess thereof; the valve seat being made up of an upper switch valve, and a lower switch valve with a plurality of insert parts extending upwards at the lower periphery thereof; in assembly, the base mount, engaged with the valve stick and mounted onto the switching control valve thereof with the protruded guide spot thereof received at the indented recess of the switching control valve and the protruded connecting section of the valve stick adapted at the receiving hole of the switching control valve therein, is adapted at the valve chamber of the valve housing therein with the retaining cavity thereof engaged with the retaining block of the valve housing for secure location thereof, stably refraining from being moved or rotated by the valve stick thereof in operation; whereby, the valve stick, pivotally switched at the base mount therein, will activate the switching control valve via the protruded connecting section and drive the upper switch valve of the valve seat joined at the bottom of the switching control valve thereof to open the valve core for water discharge; besides, with the protruded guide spot thereof as a pivoting point, the valve stick is also rotated left or right with the turning protruded block thereof moved at the turning cut area of the base mount therein to adjust the water temperature; meanwhile, the valve stick along with the two-staged valve stick seat thereof is prevented from being directly contacted with the valve housing, facilitating the easy operation of the valve stick thereof even under low torque; furthermore, the protruded guide spot of the base mount is limited to move at the indented recess of the switching control valve therein, ensuring the precise movement of the switching control valve thereof when activated by the protruded connecting section of the valve stick to open the valve core for water discharge.
