Cross-reference to Related Application

The present claims priority to Chinese Patent Application No. 201811159191.0, filed on September 30, 2018 and entitled "Air deflector Motion device and Fan", the disclosure of which is hereby incorporated by reference in its entirety.

Technical Field

The present invention relates to a fan, in particular to an air deflector motion device in a fan and a fan.

Background

Most of existing upper and lower air guide mechanisms of cooling fans on the market are manual, and part of the cooling fans with automatic upper and lower air guide mechanism have a problem of shaking during operation, specifically, during operation, an air deflector bounces faintly or suddenly.
The main reason of shaking is that the center of gravity of the air deflector is out of the axis of the air deflector during operation of the air deflector. The Chinese Patent CN1442646A discloses an air direction adjusting device of an air conditioner, which includes an air deflector and a connecting rod. A shaft sleeve is arranged on an exhaust outlet for discharging the internal air of the air conditioner. The air deflector is rotationally connected to one side of the shaft sleeve, and adjusts the air direction of the air discharged to the exhaust outlet. A motor drives the rotation of the air deflector. A protrusion for driving is arranged on the air deflector, closest to the motor, in a plurality of air deflectors, and is located at a position which is eccentric to the rear based on the center of the air deflector. A driving connecting rod is connected between the protrusion for driving and the shaft of the motor. The protrusion for driving may obtain a driving force transmitted by the motor. The protrusion for driving and an air deflector connecting part connected to the shaft sleeve are on the same horizontal axis.
Although the above technical solution has solved the problem of shaking of the air deflector when it automatically swings, it has not solved the problem of sudden shaking of the air deflector at a certain position during movement. Moreover, the above technical solution has a relatively complex structure and requires high precision of structure setting.
