Description

Technical Field

[0001] The utility model relates to the field of faucet accessories, in particular to an upper water outlet quick-connect valve core. Background Art

[0002] The water inlet and the water outlet of the existing faucet valve core are both located at the lower end of the valve core, which results in that when it is installed on the faucet body, the water outlet is lower in the height direction of the faucet body, and the water outlet arm on the faucet body and the water outlet nozzle at the end of the water outlet arm need to be connected to the water outlet, resulting in that the height of the water outlet arm can never be raised (once it is raised to be flush with the upper end surface of the faucet body, it will result in that no water path space can be established between the water outlet arm and the faucet body for the water outlet to flow out of the water outlet). If it is forced to be raised, it must be raised on the water outlet arm. A water channel space is established between the lower side and the side wall of the faucet body by means of a large arc (chamfer) transition, which affects the overall aesthetics. The above structure is aimed at the solid faucet body and water outlet arm formed by sand casting (which are overall heavy and have too high material costs). For the currently more popular hollow faucet body and water outlet arm welded from profiles / plates, it is impossible to establish a water channel space by setting a large arc (chamfer) transition. Therefore, faucets with this type of structure cannot achieve the upper installation of the water outlet arm when installing a traditional valve core. Utility Model Content
