Abstract
A valve core for a faucet includes a casing, an immovable plate, a movable plate unit, a bracket, and a lever. The movable plate unit includes two pairs of coaxial movable plates and dials. The movable plates are disposed on top of the immovable plate. A restricting mechanism is disposed between one dial and the casing, and another restricting mechanism is disposed between the other dial and the bracket. When the lever is opened, the restricting mechanism is unlocked, and the lever is rotated to adjust the water temperature of a manual spray mode of the faucet. When the lever is closed, the restricting mechanism is locked, and the lever is rotated to adjust the water temperature of an automatic spray mode of the faucet. The water temperature adjustments of the manual spray mode and the automatic spray mode are independent of each other.
