Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 to 3, an electric fan of the present invention includes a fan head 1 and a rear mesh enclosure 2, the rear mesh enclosure 2 is divided into two semicircular sub rear mesh enclosures 21 arranged in a mirror image, the sub rear mesh enclosure 21 includes two ends and a connecting portion 24 between the two ends, the two ends are respectively a rotating connecting end 22 and a detachable connecting end 23, the two sub rear mesh enclosures 21 are rotatably connected through the rotating connecting end 22, and the two sub rear mesh enclosures 21 are detachably connected through the detachable connecting end 23;

a plurality of limiting grooves 25 are formed in the connecting portion 24, a plurality of limiting columns 11 opposite to the limiting grooves 25 are arranged on the fan head 1, and clamping grooves matched with the limiting grooves 25 are formed in the side walls of the limiting columns 11.

From the above description, through the back screen panel 2 of being divided into two, can realize that back screen panel 2 directly fixes on fan head 1 through screen panel 21 behind two with the mode of fluting card sum to can make things convenient for holistic dismouting process through the setting of detachable end, simple structure, convenient operation, the practicality is strong.

Further, a detachable connecting end 23 of one of the sub rear mesh enclosures 21 is connected with a plug pin 27 through a connecting belt 29, and a detachable connecting end 23 of the other sub rear mesh enclosure 21 is provided with a plug hole 28 opposite to the plug pin 27.
