Leafless electric fan working principle

With the changes of the times, technology is also developing, and the most commonly used home appliances have also undergone tremendous changes. The humidifier that can sing, the refrigerator that can talk, the small treasure that will look at the road, etc. are no longer the imagination in the movie blockbuster, but are applied in the actual life. As a leafless fan, it is also a new technology in the 21st century.

The leafless fan is also called the air multiplier. It produces a natural and continuous cool breeze. It has no blades and will not cover the dust or hurt the curious children's fingers. What's even more amazing is that its shape is strange, and its appearance is both streamlined and refreshing. The product is inspired by the air blade hand dryer. The principle of the hand dryer is to force the air to "brush" the water on the hand through a small mouth. The air multiplier blows the air out of a slit that is 1.3 mm wide and rotates around the ring. Because the air is forced to blow out of this circle, the amount of air that can be passed can be increased by 15 times and the speed can be increased to 35 kilometers per hour.

The biggest difference between a leafless fan is that it does not have the "leaf" of a traditional fan! The bladeless fan utilizes the technology of a jet engine and a car turbocharger to draw in air through the suction hole at the bottom. An impeller hidden inside the edge of the ring ejects the air in a circular trajectory, eventually forming a strand. Intermittent cold air flow. What is important is that this air flow is smoother than that produced by a normal fan.

The wind began to "blow" out from the tiny wind tunnel in the middle of the ring: the huge ring with the bladeless fan is not exactly a gimmick, but an important component. Its center is open with a 1 The width of the millimeter is narrow, and the wind is initially blown from the air by the turbine fan in the base.

Bladeless fan, when the airflow is blown out from a 1 mm wide slit at 55 mph, it will carry the surrounding air together; next is the negative pressure, this is not difficult to understand, the air is moving forward, the ring After the air pressure will be reduced, and more air will be added to balance the air pressure - under the action of these two physical terms, the air, or the air volume of the bladeless fan, is significantly amplified to reach the extraction of the turbofan itself. 15 times. At the same time, the bladeless fan utilizes the principle of the aircraft turbine engine, which has an air inlet and an air outlet, the air inlet is in the cylindrical position, and the air outlet is the air outlet. The rotation of the motor drives the fan blade in the cylinder to rotate. The fan blade rotates the wind into the gap of the ring. Due to the decrease of the air in the cylinder and the atmospheric pressure, the air inlet will automatically enter the air and under atmospheric pressure, make progress. The gas speed is increased, so that the wind without the leaf fan is enlarged.
