When we wash our hands, we usually open the faucet to rinse our hands, then close the faucet, apply some hand sanitizer, and then open the faucet and rinse our hands after scrubbing our hands. Just the act of turning on the faucet has left hand sanitizer foam on the handle. Over time, the handle can easily breed bacteria. This is a small flaw that traditional faucets cannot avoid.
A designer who graduated from MIT designed a faucet called "Little Twist". Compared with traditional faucets, its advantage is that the switch valve is designed just below the faucet outlet. The shape of the switch valve is like a newly unearthed sprout. Water will come out as long as the switch is turned. Every time you wash your hands, you can clean the switch valve and keep it clean at all times. The switch valve is made of ceramic material and will not cause oxidation problems.
