Waterless Urinal / Waterless urinal

Waterless Urinal
Waterless Urinal

Even after a downpour of rain,the lotus leaf can always keep its surface dry and enjoy the effect of self-cleaning with the dirt on the leaf taken away by the rolling water drops.That’s why the lotus lives in the silt without getting imbrued.Inspired by such kind of feature,we apply the self-cleaning coatings to the urinal,leaving the urinal with a self-cleaning function as the lotus leaf,so that the inner wall of urinal is able to stay clean without being flushed with water.We only need to control the photosensitive water-draining piston to prevent the smell from leaking.Owing to this design conception,40000 GAL water can be saved per year.
