Felt when the rain under a big umbrella on rainy days is not enough, this time need a simple and quick method to make an umbrella, my design is from the concept of air, make the edge of the umbrella form an air curtain, into a larger umbrella.
Air umbrella use water potential energy, the rain fell in the gravity on the surface of the umbrella into potential energy, basic structure and function is through the air from the air inlet into the mouth, and then from the jet, air umbrella provides the user with an air curtain. This air curtain can have the effect of increase the umbrella surface area, to prevent the rain.
