Description

Bladeless fan with function of making an uproar is fallen

Technical Field

The utility model relates to a tourist product technical field specifically is a bladeless fan with function of making an uproar falls.

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 fan can be increased by 15 times, the speed per hour can be increased to 35 km/h at most, and the inspiration of the bladeless fan is originated from the air blade hand dryer. The principle of the air vane hand dryer is to force air through a small orifice to "blow" the water on the hands, and the air doubler is to blow the air out of a 1.0 mm wide slit that rotates around a circular amplifier. Since 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 reach 35 km. The air flow of the air multiplier is smoother than that of the wind generated by a common fan. It generates an amount of air equivalent to the best performing fan on the market. Because there are no fan blades to 'cut' the air, the user does not feel the stage-impact and wave-like irritation. The novel air-conditioning pillow has the advantages that people feel more natural and cool through continuous air flow, when people travel and carry the pillow for use, the noise is too large, the generated noise can affect the sleep and the mood of people, the hearing can be damaged, the vision can be affected for a long time, the nervous system can be affected, and the fatigue is caused.
