This is a device that uses air currents to stop the rain. It has abandoned the 2400-year-old ribs and umbrellas that we have adopted. There is only one umbrella handle. Having said that, it really seems that it takes a bit of courage to take this "stick" and pour into the heavy rain.

This Umbrella has no umbrella can use air flow
Umbrella is a product from a new domestic company. Its developers describe it as follows: “Every place on the earth has air. We also know that air flow can change the trajectory of an object, and the faster the air flow, the greater the energy. The outflow can create an invisible barrier around the user, changing the trajectory of the raindrop, and making the user less likely to rain."

The umbrella consists of three parts: the motor, the lithium battery, and the controller. The top motor is the key to controlling air flow.
At present, Air Umbrella has designed three different models for different users and different uses: a model for women only, it is relatively small, about 30 cm in length, weighs 500 grams, but the battery life is relatively short, only 15 minutes; The b model is a basic model, with a length of approximately 50cm, a weight of 800g, and a battery life of approximately 30 minutes. Model c is an adjustable-length model, with a minimum length of 50cm, a maximum length of 80cm, a weight of approximately 850g, and battery life. It is also about 30 minutes.

At present, the Air Umbrella is still in the research and development stage. Everyone can look at the actual rain protection effect from the video provided in the article. Developers say it can only shelter one or two people nowadays. Of course, if the rain is slightly smaller, it can accommodate more people, although they may be very insecure under the umbrella. In addition, developers said that they will do more research on the appearance of the air umbrella and the battery life. Once people do not hold it, there is no image at all. Secondly, they will not be very embarrassed because the battery will soon be unplugged. .
It is reported that a model of this air umbrella (with charger and car charger) is priced at 128 US dollars (about *** 784 yuan); b model (with charger and car charger) priced at 138 US dollars ( About *** 845 yuan); c model (with charger and car charger) is priced at 148 US dollars (about *** 906 yuan). There are also other product combinations available, and early supporters can also buy at a slightly lower price, but it seems that the quota is now exhausted. Like friends can go to support, but although the technology content is full, but the price is nearly 1,000*** tall umbrella, it seems not me and other ordinary people can afford ah.
