Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of valve core, especially a water faucet valve core of preventing abnormal sound. BACKGROUND

[0002] The water faucet valve core is the core component of the fluid control device, and its structural performance directly affects the precision of water flow regulation and use experience. The water faucet valve core usually comprises a rotating seat, a handle and a valve piece, wherein the valve piece is provided with a plurality of water passing holes corresponding to the water inlet and the water outlet. The user drives the rotating seat to slide on the surface of the valve piece by operating the handle, so as to realize the opening and closing of the water flow channel and the flow regulation function.

[0003] In order to ensure the smooth operation of the valve core, the prior art usually applies lubricating oil to the bottom bearing surface and the side wall of the rotating seat. However, in the actual assembly process, the application of lubricating oil is usually performed manually. Since the manual oil application operation has certain uncontrollability, the amount of lubricating oil is difficult to accurately control. If the lubricating oil is applied in excess, the excess lubricating oil is easy to overflow along the movement track of the rotating seat to the valve piece area. The lubricating oil will flow into the upper end surface of the valve piece. Since there may be gaps at the connection of the upper end of the valve piece, air may mix into the lubricating oil through the gaps to form an oil-gas mixture. In the common valve core design, the upper end surface of the valve piece is usually provided as a flat structure. When the user operates the handle to control the valve core, since the upper end surface of the valve piece is a flat structure, the air is not easy to be discharged from the upper end surface of the valve piece. Thus, the oil-gas mixture is easy to cause irregular sound due to the rupture of air bubbles and the vibration of liquid in the process of handle operation, thereby causing abnormal sound phenomenon. The abnormal sound not only affects the use experience of the user, but also may adversely affect the long-term stable operation of the valve core. Therefore, it is necessary to improve.
