What is an umbrella called when it sprays out a stream of air to block the rain?

/d/2010-03-22/10253970084.shtml (Picture) Korean designers create air umbrellas: jet air to protect against rain Sina Technology News Beijing time on March 22, according to foreign media reports, Korean designers Je Sung Park and Woo

Jung Kwon has created an umbrella in the unconventional sense.

This alternative umbrella has no canopy, and its hollow tube emits gas to form a solid barrier between the user and the rain.

In addition, users can control the length of the umbrella handle and the size of the air cap.

Although it is difficult for us to accept this design from the perspective of physics and engineering, the air umbrella embodies the soul of unconventional design.

Air umbrellas use wind to protect users from rain.

This is an innovative design that breaks people's inherent ideas about umbrellas.

By improving the traditional umbrella design and adding creative elements, air umbrellas allow users to enjoy greater convenience.

Additionally, it is also an eco-friendly umbrella as it reduces the need for plastic bags.

Schematic diagram of the functional structure of an air umbrella: 1. Basic structure and function (the upper part is the air outlet, the lower part is the air inlet): By air entering from the air inlet and then ejected from the air outlet, the air umbrella provides an air curtain for the user.

This air curtain can function as an umbrella cover to block rainwater.

2. Controller (controls power supply and air barrier size): Through simple operations, users can control the size of the air curtain.

The specific size of the air curtain depends on how many people use this alternative umbrella.

3. Length control: The length of the air umbrella can be controlled to achieve the word "portable" to the greatest extent.
