It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a ceiling-mounted fresh air air conditioner indoor unit, including a floor 1, the bottom of the floor 1 is fixedly connected to an adjustment mechanism 3, the adjustment mechanism 3 includes a connecting sleeve 301 and a fixing plate 307, the outer surface of the connecting sleeve 301 is symmetrically provided with a plurality of connecting grooves 302 near the bottom, the inner surface walls of the plurality of connecting grooves 302 are rotatably connected to connecting rods 303, the outer surfaces of the plurality of connecting rods 303 are fixedly connected to swing blades 304, one end of the plurality of connecting rods 303 is provided with a worm gear 305, the outer surfaces of the plurality of worm gears 305 are meshingly connected to worms 306, the top of the connecting sleeve 301 It is fixedly connected to the bottom of the floor 1, and the outer surface of the fixed plate 307 is fixedly connected to the U-shaped plate 308, and the outer surface of the U-shaped plate 308 is provided with a driving motor 309, and the output end of the driving motor 309 passes through the outer surface of the U-shaped plate 308 and extends to one side, and the output end of the driving motor 309 is fixedly connected to a rotating rod 310, and one end of the rotating rod 310 is fixedly connected to a first pulley 311, and the outer surface of the first pulley 311 is rotatably connected to a transmission belt 312, and the inner surface wall of the transmission belt 312 is rotatably connected to a second pulley 313, and the outer surface of the fixed plate 307 is fixedly connected to the outer surface of the connecting sleeve 301.

[0023] The effect achieved by the entire embodiment 1 is that when a ceiling-mounted fresh air air-conditioning indoor unit is used, the air-conditioning indoor unit body 2 is first installed at the bottom of the floor 1, and then the driving motor 309 on the U-shaped plate 308 is started, and its output end directly drives the rotating rod 310 to rotate. At one end of the rotating rod 310, a first pulley 311 with a smaller diameter is installed, which rotates with the rotation of the rotating rod 310. The first pulley 311 is connected to the second pulley 313 with a larger diameter through a transmission belt 312 to form a transmission. Since the diameter of the first pulley 311 is smaller than that of the second pulley 313, when the first pulley 311 rotates, the power transmitted through the transmission belt 313 will cause the second pulley 312 to rotate at a slower speed, thereby achieving a deceleration effect. During the rotation of the second pulley 313, it can effectively drive the worm 306 to rotate. 6 rotates, and the meshing teeth thereon precisely mesh with the multiple worm gears 305, thereby ensuring that the worm 306 can synchronously drive the worm gears 305 to rotate, ensuring that the multiple worm gears 305 can rotate synchronously and orderly with the rotation of the worm 306. During the rotation of the worm gear 305, the connecting rod 303 is driven to rotate in the connecting groove 302. Subsequently, this rotational motion is transmitted to the swinging blade 304 by the connecting rod 303, thereby driving the swinging blade 304 to perform a corresponding slow swinging motion to achieve the required airflow adjustment or guiding function. Under the action of the adjustment mechanism 3, the air conditioner swinging blade 304 can achieve a relatively large swing, avoiding the angle limitation that some fan blades may be subject to when swinging inside the machine, ensuring that the air conditioner can give full play to its due performance during use, such as optimizing air circulation, etc., thereby improving the overall use efficiency.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the air conditioner indoor unit body 2 is fixedly installed at a position near the center of the bottom of the floor 1, a mounting plate 4 is provided near the bottom of the outer surface of the connecting sleeve 301, a plurality of threaded rods 41 are symmetrically provided near the top of the outer surface of the mounting plate 4, and a dustproof net 42 is provided near the center of the bottom of the mounting plate 4.

[0025] The effect achieved by the entire embodiment 2 is that, during use, the mounting plate 4 needs to be first firmly mounted on the outer surface of the connecting sleeve 301. At this time, the threaded rods 41 are screwed into the outer surface of the mounting plate 4 one by one, so that the mounting plate 4 can be firmly fixed. The dustproof net 42 can effectively prevent dust from entering, thereby ensuring the internal cleanliness of the equipment and improving the operating efficiency and service life of the equipment.

[0026] Working principle: When in use, first start the drive motor 309 to drive the rotating rod 310 to rotate. At one end of the rotating rod 310, a first pulley 311 with a smaller diameter is installed. It rotates with the rotation of the rotating rod 310. The first pulley 311 is connected to the second pulley 313 with a larger diameter through a transmission belt 312 to form a transmission. Since the diameter of the first pulley 311 is smaller than that of the second pulley 313, when the first pulley 311 rotates, the power transmitted by the transmission belt 313 will cause the second pulley 312 to rotate at a slower speed. During the rotation of the second pulley 313, it can effectively drive the worm 306 to rotate. As the worm 306 rotates, Rotation, by meshing with multiple worm gears 305, it is ensured that the worm 306 can synchronously drive these worm gears 305 to rotate. During the rotation of the worm gear 305, the connecting rod 303 is driven to rotate in the connecting groove 302. Subsequently, this rotational motion is transmitted to the swing leaf 304 by the connecting rod 303, thereby driving the swing leaf 304 to perform a corresponding slow swinging motion to achieve the required airflow regulation or guiding function, and then the mounting plate 4 is firmly mounted on the outer surface of the connecting sleeve 301. At this time, the threaded rods 41 are screwed into the outer surface of the mounting plate 4 one by one, so that the mounting plate 4 can be firmly fixed, and the dustproof net 42 can effectively prevent dust from entering.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
