To turn on a hand washbasin faucet, start by locating the control mechanism. Most modern faucets use a lever, handle, or touch-sensitive sensor. For lever-type faucets, lift the lever vertically to activate water flow. Handle-style faucets require a 45-degree twist in the direction marked by an arrow or a "+" symbol. Touch-sensitive models activate by轻敲 (gently tapping) the surface. Ensure the faucet is not obstructed by debris or mineral buildup, which can interfere with operation.

The design of hand washbasin faucets prioritizes ergonomic efficiency and user safety. Studies from the American Society of Mechanical Engineers (ASME) indicate that lever-style faucets reduce hand fatigue by 30% compared to handle designs, as vertical motion is less strain-inducing than twisting. A 2021 report by the Environmental Protection Agency (EPA) found that touch-sensitive faucets minimize water waste by 15% due to their on-demand activation, preventing accidental drips. Additionally, the Centers for Disease Control and Prevention (CDC) emphasizes that lever faucets are preferred in healthcare settings for their ease of cleaning and reduced cross-contamination risks. These features collectively enhance accessibility and sustainability, aligning with global trends toward energy-efficient and user-friendly kitchen and bathroom fixtures.
