[0002] Central air conditioning is an air conditioning system that provides cooling, heating, and air conditioning to multiple rooms or areas through centralized equipment. Compared with traditional single air conditioning units, central air conditioning uses centralized control and whole-house air circulation, which can more efficiently regulate the temperature, humidity, and air quality throughout the building.

[0003] Chinese patent document with publication number CN210980292U discloses a solar central air conditioning outlet adjustment device, including an outlet outer frame, an adjustment frame inside the outlet, and the top of the adjustment frame being connected to the inner wall of the outlet outer frame via a hinge. Fixing holes are evenly distributed on the left side of the bottom end of the outlet outer frame. The end of the locking block away from the filter plate extends into the interior of the slot. Push rods are inserted into the upper and lower ends of both sides of the outlet outer frame.

[0004] Through research, it was found that although the device can adjust the air outlet angle of the central air conditioning, in office places with many people, no matter how the air outlet angle is adjusted, it is easy for the air to blow directly on people, which can easily cause physical discomfort to users. Therefore, this utility model proposes a central air conditioning outlet adjustment device to solve the above problems. Utility Model Content
