Umbrella is a must-have tool when we travel, because sometimes it will rain, we can prepare an umbrella to play a good preventive role, so the umbrella is very important for our daily life, it is also necessary Indispensable, but have you ever seen a black technology umbrella? I believe many of my friends don't know about black technology umbrellas! So today, let’s take a look at the black technology umbrella.

Our Chinese Wizards invented a black technology umbrella, and this black technology umbrella is still an air umbrella, as the name suggests is an umbrella without obstructions, then how does this black technology umbrella rain? In fact, it is a stick that relies on the flow of air to prevent rain. I believe that many friends have been very curious at this time. From the appearance, it is a stick or a sprayer.

In fact, the principle of this umbrella is very well explained, that is, the airflow above the airflow is exhausted to the surrounding area, thereby playing the role of preventing rain, and changing the movement track of the rainwater through the airflow, so that it can play a role in preventing rain. The umbrella was invented by a Chinese genius, and it was supported by many people. Even the young man was invested, but in the end it was not.

Then someone will worry, if the rain is very big, will this black technology umbrella be not good? In fact, there is absolutely no need to worry about this. If the rain is very big, it means that the energy of the rain is very large, but the air flow of the black technology umbrella is bigger, and the rain will be bounced faster. This umbrella is rain. The bigger the better, the less useful it is if it is drizzy.
