[0002] Ventilation is a basic condition that must be met in residential or office places. Only good ventilation can ensure that harmful gases in the building are discharged outdoors in a timely manner to avoid harm to people. Ventilation methods are usually divided into natural or mechanical methods to allow wind to circulate without obstruction.

[0003] At present, the existing utility model has a simple structure and is easy to produce. When a fan is needed to ventilate the indoor and outdoor environments, it is only necessary to drive the transmission shaft to rotate through the reduction motor, and the wire rope can be reeled in by the reel, thereby pulling the rack to move upward in the frame, thereby driving the gear to rotate, and driving the baffle to rotate in the frame through the rotating shaft to open the opening of the air duct, and by controlling the rotation angle of the baffle, the air outlet direction of the ventilation structure can be adjusted.

[0004] For example, a ventilation structure for architectural design disclosed in the authorization number CN218328528U includes an air duct, a fan is fixedly installed inside the air duct, a frame is fixedly installed on the inner wall of the openings on both sides of the air duct, the inner side of the frame has multiple shafts connected to rotate from top to bottom, the outer wall of the shaft is fixedly installed with baffles, the outer walls of the two frames are jointly penetrated by a transmission shaft, the transmission shaft is rotatably connected to the frame, a reduction motor is fixedly installed on the outer wall of one frame, the output shaft of the reduction motor is fixedly connected to one end of the transmission shaft, and the baffles on the two frames are connected to the transmission shaft through a transmission mechanism. However, it is unclear how to conveniently install and fix the air duct for such a ventilation structure for architectural design, and it is not convenient to remove the fan for maintenance and replacement.

[0005] It can be seen from the solutions disclosed in the above-mentioned existing patent documents that it is unclear how to conveniently install and fix the air duct, and it is not convenient to dismantle the fan for maintenance and replacement. Therefore, it is necessary to improve the existing technology. Utility Model Content
