Description

Technical Field

[0001] The utility model relates to the technical field of bathroom furniture, in particular to a faucet. Background Art

[0002] Existing basin faucets for bathrooms are widely used and are popular among consumers due to their many advantages, such as easy installation, affordable price, practicality, lightness and dexterity. When the basin faucet is in operation, cold and hot water from the outside are introduced into the valve body through the water inlet hose. The cold and hot water are mixed by the axis hot and cold water control unit and then flow out for use.

[0003] Existing faucets generally include a shell, a mounting tube, a valve core and a handle. The valve core is arranged in the mounting tube, the handle is arranged on the upper end surface of the shell, the upper end of the valve core extends into the shell and is connected to the handle, and the handle and the valve core cooperate through teeth. When the handle is turned, the valve core is driven to rotate, thereby achieving control of water output and water flow. However, the handle of the existing faucet is directly connected to the valve core, resulting in a large handle structure and inconvenient operation. In addition, there is a gap between the handle and the valve core through the cooperation of teeth. After long-term use, it is easy to shake, resulting in poor stability and inability to drive the valve core to rotate well. Summary of the Invention
