Problems solved by technology
[0002] At present, electric fans are widely used in households and industrial places because of their environmental protection and practical features. However, although most electric fans have net covers, it is impossible to avoid the involvement of hair and other small foreign objects. Damage the electric fan itself, and even cause harm to the user. Even if the power supply can be cut off at the first time in a critical situation, the fan will continue to rotate under the action of inertia, which poses a serious safety hazard

The invention discloses a safe electric fan. A turntable is arranged on one side of a driving shaft, a conduction part is arranged on the side, opposite to the turntable, of a driven shaft, an empty bin is arranged on the inner side face of the conduction part, a group of connecting rods inserted into the empty bin of the conduction part is connected inside the empty bin through an engagement structure, a middle seat is arranged on one side of the connecting rods, multiple positioning pins are arranged on the end face, opposite to the turntable, of the middle seat and are distributed on a circumference in an equally spaced mode, multiple arc-shaped empty grooves are formed in the end face, opposite to the middle seat, of the turntable, and the arc-shaped empty grooves correspond to the positioning pins. When foreign matter is involved into the safe electric fan, a transmission part can break away from the turntable in time to play the role of immediately stopping fan rotation.
Description
technical field [0001] The invention relates to the field of electrical appliances, in particular to a safety electric fan. Background technique [0002] At present, electric fans are widely used in households and industrial places because of their environmental protection and practical features. However, although most electric fans have net covers, it is impossible to avoid the involvement of hair and other small foreign objects. Damage to the electric fan itself will cause harm to the user. Even if the power supply can be cut off at the first time in a critical situation, the fan will still continue to rotate under the action of inertia, which poses a serious safety hazard. Contents of the invention [0003] The purpose of the present invention is to provide a safety electric fan to solve the problems raised in the background art above. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A safety electric fan...
