Height-adjustable electric fan

Abstract

The invention discloses a height-adjustable electric fan. A turntable is arranged on one side of a driving shaft, and a conduction member is arranged on one side, opposite to the turntable, of a driven shaft. An empty bin is arranged on the inner side face of the conduction member, and the inner part of the conduction member is connected with a group of connecting rods inserted into the empty bin of the conduction member through an engaged structure. A middle seat is arranged on one sides of the connecting rods, and a plurality of locating pins are arranged on one end face, opposite to the turntable, of the middle seat and are equidistantly distributed on the circumference. A plurality of arc-shaped empty slots are formed in one end face, opposite to the middle seat, of the turntable, and the arc-shaped empty slots correspond to the locating pins. When a foreign body is drawn into the inner part of the electric fan, a transmission part can be rapidly disengaged from the turntable so as to stop the fan from rotating.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a height-adjustable 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 object of the present invention is to provide a height-adjustable 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] ...
