Description

Technical Field

[0001] This utility model relates to a pull-out water outlet device. Background Technology

[0002] Pull-out faucets, as an important functional component in modern kitchens and bathrooms, significantly enhance user convenience with their flexible pull-out design. Their basic structure typically consists of three parts: the faucet body, the valve core assembly, and the pull-out hose and spout. The faucet body serves as the main frame, integrating hot and cold water inlet channels and a mixing chamber. The valve core, as the core control component, adjusts the mixing ratio and flow rate of hot and cold water through a mechanical structure. The pull-out hose, made of flexible material (such as stainless steel braided hose or silicone tubing), connects the valve core outlet to the spout and automatically resets after being pulled out using gravity balance or a magnetic attraction device. The spout is often designed with a dual-mode switching structure for both shower and direct current sprays to adapt to different usage scenarios.

[0003] In existing technologies, the water flow control of pull-out faucets primarily relies on the mechanical operation of the valve core. Users adjust the mixing ratio of hot and cold water and the on / off flow by rotating or pressing the handle to move the ceramic disc inside the valve core. However, existing pull-out faucets still have some significant drawbacks in terms of functionality and design. First, most pull-out faucets only support a single mechanical handle control method, requiring users to operate the faucet through physical contact, which is inconvenient in certain scenarios (such as when hands are covered in oil or when a quick start / stop of the water flow is needed).
