There’s one phenomenon in life: when we’re cleaning utensils by cleaning solution, we usually forget to close the water tap. Since we think that we will quickly finish the dish washing and flush away its above cleaning solution, however, water resources are being wasted. This is not a good habit, so we designed a faucet which could outflow cleaning solution to kick it. We can switch between clean water and cleaning solution, and avoid wasting water in this process. This will help people to cultivate a good habit.
