Abstract: A portable cooling fan. The fan includes a fixed rack arranged under a frame body, a wheel set disposed laterally on the fixed rack, a support rod located at a position opposite against the wheel set for stabilization, and a handgrip arranged on an upper position of the fan body for carrying the cooling fan easily. In addition, an indented costa is formed on each of the leaf blades by pressing, to enhance intensity of the leaf blades and create turbulence to enlarge the blowing area. The frame body includes a protective mantle, which is supported with a plurality of reinforcement ribs.

Abstract: The present invention relates to a multiple current safety fan, which comprises a body; a motor seat installed in the body, the two sides of the body being separately installed with a locking hole; two screen covers separately installed on the front side and the rear side of the body, the screen covers being annularly and outwardly installed with a plurality of ribs, and the screen covers being reinforced by reinforcing ribs having a U-shape and installed in crisscross. The screen cover on the rear side or the body is indented inwardly. and the interior At the center part of the screen cover is connected to the motor seat inside the body. The leg seat is fastened to the locking holes on the two sides of the body, and the two ends thereof are protruded with two supports. The supports are installed with a plurality of perforated adjustment holes so that the locking holes of the body and the adjustment holes of the supports are used to adjust the height of the body of the electric fan.

Abstract: A cooling fan with spray function mainly comprises a plurality of T-shaped jet couplings, a single-way jet coupling, a plurality of hose segments to be connected with the jet couplings, and a hose segment with a coupling T for connection with the faucet and a first T-shaped jet coupling to form a circular channel for water spray. After water enters a through hole of a nozzle via a blowhole, it will flow along grooves on a rotor to drive the rotor to rotate and thereby spray foggy speedy helical droplets out of a spout in the nozzle for enhancing cooling effect or watering flowers.
