Fan

Abstract

The invention discloses a fan, which comprises a power device and fan blades, wherein fluid passages are arranged in the fan blades, multiple fluid leading-in holes of the fluid passages are arranged in the front surfaces of the fan blades; the fan also comprises a motor, an air suction port of the motor is communicated with the fluid passages of the fan blades through conduits, and an exhaust port of the motor is a fluid leading-out hole. According to the technical scheme, a pressure difference transfer area is formed at the periphery of the fan, the flow rate of the pressure difference transfer area is much higher than the air speed of the fan and a great pressure difference with a positive pressure zone generated by the discharged fluid is formed; the pressure difference is much greater than that of a conventional fan, the slow fluid in the positive pressure zone certainly transfers to the quick fluid in a negative pressure zone instantly and simultaneously drives the surrounding fluid to transfer pressure difference by taking the negative pressure zone as a center and drives high pressure to transfer pressure difference to the low pressure zone, just like water flowing to a lower position. By the matching of a pressure difference transfer zone with soft wind discharged by a fan, comfortable air flow can be formed under the interaction of the pressure difference transfer zone and the soft wind, thereby achieving a good effect.

Description

technical field [0001] The invention relates to a household device, in particular to a device that interacts through fluid pressure difference and fan exhaust. Background technique [0002] Fans have been widely used as a kind of ventilation and cooling equipment, ranging from small household exhaust fans to large fans used in industry, all of which generate exhaust volume according to the power, so the effect achieved is not ideal. The suction and exhaust generated by the rotation of the impeller make the air flow, but the high-speed air flow makes people feel very uncomfortable, and the slow wind speed has no effect. Equipment that uses fans to generate pressure cannot generate high pressure only through suction and exhaust, so it is necessary to improve the fan. [0003] The strong suction and exhaust of the traditional fan produces a large air flow, and the slower wind speed does not feel and has no effect. Although the faster wind speed can generate a certain pressure ...

AI Technical Summary

Problems solved by technology

[0003] The strong suction and exhaust of the traditional fan produces a large air flow, and the slower wind speed does not feel and has no effect. Although the faster wind speed can generate a certain pressure difference, the surrounding air is transferred to the wind flow, but it blows to the human body and feels Uncomfortable, so the wind speed can have a better effect after the pressure difference is formed between the positive and negative pressures, but the traditional fan can only form a fast wind speed through a high flow rate to generate a slightly low air pressure, making the surrounding environment slower. The high air pressure generated transfers to the low air pressure generated by the high wind speed, thus forming the air flow around the fan to cool down the heat, but the faster wind speed makes people feel uncomfortable and is not good for the body. Moreover, the low air pressure generated by the high flow speed of the fan , because the flow rate discharged by ordinary household fans is not too high, and the pressure difference with the surrounding air is not large, so the pressure difference transfer area is not fast, and the air flow effect is not good.
