[Cool] USB rotating chair that sends cool breezes

With the arrival of the evil summer, facing the cheap office chair in the office, we can only helplessly lay a bamboo mat on it to reduce the high temperature under our butts. A Japanese design company came up with such a wonderful idea: adding a set of air supply and ventilation device under the chair. As long as you plug in the USB interface and turn on the switch, a gentle cool breeze will blow towards your "butt". This allows office workers who sit for eight or nine hours in the office to be free from the suffocating dampness under their butts.
