Everyone gets the problem that drops of water are always bedewing
the floor when folding umbrellas.It's uncomfortable.In this design,
a sponge absorbing water is put into the top of the umbrella.As a result,
after we fold the umbrella,drops of water will be absorbed by it.In

plants. To start from scratch to eliminate a waste of water.It's
everyone's responsibility to protect our environment.
