Abstract

The invention discloses an electric fan with all-around wind direction. A swivel bearing is arranged on a base of an electric fan, and a supporting arm is installed on the swivel bearing; a power cord of a fan head penetrates the center of the supporting arm, and is connected with an external power source by the mode of slip ring connection in the base, thereby preventing the power cord from being enwound; and a small fan is installed on one part of the fan head, which is deviated from the rotary axle center of the supporting arm, and a force moment is supplied for the rotation of the fan head. The electric fan with all-around wind direction of the invention can be arranged in the center of a space to provide people all around with fan wind, thereby achieving the purpose of 360-degree rotation of the fan head.

Description

technical field [0001] The invention relates to an electric fan, especially a seat fan or a table fan. Background technique [0002] No matter the current electric fan is seated or desktop, the wind direction is all in one direction. Although it has a shaking head function, it can only swing at a maximum angle of 120°, and cannot rotate in the full wind direction, that is, 360°. Contents of the invention [0003] The invention provides a 360° rotating all-wind direction electric fan for the purpose of achieving 360° rotation. The technical solution of the present invention is that it includes a base of an electric fan, a support arm and a fan head, and is characterized in that: [0004] 1. There is a rotating bearing on the base of the electric fan, and the support arm is installed on the rotating bearing and can rotate freely; [0005] 2. The power cord of the fan head passes through the center of the support arm, and after passing through, it is connected to the extern...
