Background

In order to adjust the air flow direction, air outlets of air conditioning appliances such as cooling fans, air conditioners and the like are provided with air deflectors for adjusting the air direction, so that cold air (or hot air) can be blown out in a set direction. The traditional horizontal air deflector is manually controlled, and the positioning effect is achieved through the friction force of close fit between the rotating shaft of the air deflector and the hole of the air outlet frame, so that the air outlet direction is maintained in one direction. When the electric appliance is used for a long time, the rotating shaft and the hole are smooth due to long-term abrasion, and the friction force between the rotating shaft and the hole is reduced, so that the air deflector is not easy to position. When the air guide plate needs to be adjusted to change the air outlet direction, the air guide plate cannot be effectively positioned, and under the action of gravity, the air guide plate rotates downwards, so that the wind can only blow downwards.
