Problems solved by technology

But the current portable fans can be said to be a bit of a misnomer: the motors and blades of most fans cannot be folded, which takes up more space and is inconvenient to carry around; and the rotation of the blades will drive the fan to vibrate. The support is unstable, which can easily cause the fan to fall. The stability of all supports is an important factor to ensure the stable operation of the fan

Abstract

The invention discloses a portable electric fan achieving rotation driving storage. The portable electric fan comprises a square supporting frame, an electric fan body and a rotation driving storage device. The electric fan body comprises a sliding supporting seat, a motor and three blades. The upper portion of the sliding supporting seat is cylindrical, and the lower portion of the sliding supporting seat is hemispheric. A cylindrical-groove-shaped lifting groove is formed in the upper end face of the supporting frame. A horizontal containing groove is formed in the rear end face of the supporting frame and communicates with the lifting groove. The lower end of the lifting groove is formed to be in a hemispheric shape matched with the lower portion of the sliding supporting seat. The motor is fixed in the sliding supporting seat. A cylindrical blade seat is fixed to an output shaft of the motor. The three blades are evenly distributed on the blade seat and can be folded in the direction away from the motor. The rotation driving storage device is arranged on the front portion of the supporting frame and drives the sliding supporting seat to ascend, descend and rotate. The portable electric fan is simple in structure and convenient to operate; the electric fan body can be stored in the supporting frame; carrying is convenient; supporting is stable; and the work stability of the electric fan is guaranteed.

Description

[0001] Technical field: [0002] The invention relates to the technical field of small household appliances, in particular to a portable electric fan that is rotatably driven and stored. Background technique [0003] The fan is a small household appliance that we often use in the summer. For people who need to travel frequently or travel far away, portable fans are particularly important. However, the current portable fans can be said to be a bit of a misnomer: the motors and blades of most fans cannot be folded, so they take up more space and are inconvenient to carry; and the rotation of the blades will drive the fan to vibrate. The support is unstable, which can easily cause the fan to fall. The stability of all supports is an important factor to ensure the stable operation of the fan. Summary of the invention [0004] The purpose of the present invention is to provide a portable electric fan that can be rotatably stored in view of the shortcomings of the prior art. [0005] In o...
