Description

Technical Field

[0001] The utility model relates to the technical field of faucet valve cores, and in particular to a valve core and a faucet. Background Art

[0002] The valve core is a key component for controlling the water flow in the faucet. The existing valve core that can produce mixed water usually controls the water temperature by rotating, and uses the lever to switch the water flow. However, the lever principle makes the lever move in opposite directions at both ends when in operation, and a separate dial is required to cooperate with the lever to drive the valve plate to move to achieve the opening and closing of the water path. This method has many parts and components, many assembly steps, and high cost. At the same time, due to the active cooperation between the dial and the lever, there is mutual friction at the active connection. After long-term use, the switch may not be in place after wear and tear, resulting in a decrease in water output. Utility Model Content
