Description

technical field [0001] The invention relates to an air supply structure, in particular to an adjustable indoor air supply device. Background technique [0002] The structure of the current indoor air supply system is relatively simple. After the outdoor fresh air is agitated by the fan and passes through the filter, it enters the room through the air supply opening in the room; and regardless of the amount of air supply, it enters the room through the fixed air supply opening. [0003] However, in some occasions, such as offices, the air supply outlet is generally located directly above the office area. When the air supply volume is small, the fresh air will dissipate soon after being discharged from the air supply outlet, and the fresh air will not directly blow on people's heads. or on the body; but if the indoor air quality is poor and the air supply volume is large, people will feel obvious wind blowing on the head and body. When the outdoor air is colder or hotter, it w...
