Background
The bladeless fan is also called an air doubling machine, can generate natural and continuous cold wind, and cannot cover dust or hurt fingers inserted by children due to no blades. More wonderful is that the appearance is streamline and fresh. Inspiration stems from air vane hand dryers. The principle of the hand dryer is to force air through a small opening to "brush" the water on the hand, and the air doubler blows the air out of a 1.3 mm wide cut rotating around a circular ring. Because the air is forced to blow out from the circle, the air quantity passing through the circle can be increased by 15 times, and the speed per hour can be increased to 35 km/h at most. Bladeless fans were first introduced in the United kingdom on 10 months and 12 days in 2009. The second generation was introduced in hong Kong in 2 months of 2011. The bladeless fan can be divided into a table type bladeless fan and a hanging type bladeless fan (a bladeless ceiling fan lamp), the energy consumption of the novel electric fan is reduced by one third compared with that of a common electric fan, and furthermore, because blade parts of a traditional electric fan are abandoned, the leather type of the fan is innovated, the fan becomes safer, more energy-saving and more environment-friendly. However, the first bladeless fan has low wind power on the premise of saving energy, so that the power consumption of products sold on the market has to be increased in order to increase the wind power.
In hot summer, people often use various bladeless fans as cooling means, and among the bladeless fans, the bladeless purifying fan is popular with customers, but when the fan breaks down, the fan is often of an integrated structure, so that difficulty is added to maintenance during the failure.
