Abstract

The utility model discloses a fan, comprising a power device and blades. A fluid channel is arranged inside each blade; and a plurality of fluid lead-in openings for the fluid channel are arranged on the front face of each blade; the fan further comprises a motor; air suction ports of the motor are communicated with the fluid channels of the blades through guide pipes; and air exhaust openings of the motor are fluid lead-out openings. According to the technical scheme, a pressure difference transferring area is formed around the fan; a flow speed of the pressure difference transferring area is faster than an air speed of the fan, so that the large pressure difference is formed in a positive-pressure area generated by discharged fluid; the pressure difference is much larger than that of the traditional fan, so that slow fluid in the positive pressure area instantly transfers to faster fluid in a negative pressure area; meanwhile, the pressure difference is transferred to a center by driving the surrounding fluid to the negative pressure area, and the pressure difference is transferred from a low pressure to high pressure, just like water flowing to a lower part. The very comfortable air flow is formed by a pressure difference transfer area with flexible air exhausted by the fan under the interactive effect of the pressure difference transferring area and the more flexible air, so that the good effect can be achieved.
