After raining, the used umbrella often makes the ground too wet. This design can perfectly solve the problem with gravity.
We add Recycling raindrops at the top of the umbrella. When using umbrellas, Recycling raindrops will retract automatically because of gravity ball.When closing umbrellas, Recycling raindrops will open
automatically because of gravity ball. And then it can collect the rainwater slipping from the surface of umbrella, so the ground is no wet any more.
