[0020] Reference Figure 1-Figure 4As shown, the present invention provides a technical solution: it includes a unit box body 1, the surface of the unit box body 1 is provided with an air outlet, a plurality of universal wheels 2 are installed at the lower end of the unit box body 1, a fixing frame 3 is fixedly connected to the surface of the unit box body 1, a plurality of long rods 4 are fixedly connected to the inner wall of the fixing frame 3, a rotating plate 5 is rotatably connected to the arc surface of the long rod 4, a connecting rod 7 is fixedly connected to one side of the rotating plate 5, a plurality of connecting rods 7 are fixedly connected to one end of the rotating plate 5 away from the rotating plate 5, a sliding hole 10 is provided on one side of the fixing frame 3, a sliding rod 9 is slidably connected to the inner wall of the sliding hole 10, one end of the sliding rod 9 is fixedly connected to the curved plate 8, a plurality of slots are provided on one side of the fixing frame 3, and the sliding rod 9 The end away from the arc plate 8 is fixedly connected with an arc block 12, and a plug rod 13 is slidably inserted in the arc block 12. The plug rod 13 is slidably connected to the inner wall of the slot of the fixing frame 3, and the end of the plug rod 13 away from the rotating plate 5 is fixedly connected with a round block 14. Through the cooperation of the rotating plate 5, the connecting rod 7, the arc plate 8, the sliding rod 9, the plug rod 13 and other components, the angle of the rotating plate 5 at the air outlet can be flexibly adjusted, thereby changing the size of the air outlet direction and the air outlet position, so that the wind can be more accurately directed to the required area. Compared with traditional equipment with fixed air outlet directions, the convenience and flexibility of use are greatly improved, and the diversified use requirements can be better met. The arc surface of the plug rod 13 is covered with a spring 15, the two ends of the spring 15 are fixedly connected to the round block 14 and the arc block 12 respectively, and the spring 15 is arranged on the arc surface of the plug rod 13. The elastic force of the spring 15 is utilized to enable the plug rod 13 to automatically reset and firmly insert into the slot of the fixing frame 3, thereby simplifying the operation steps, improving the convenience and stability of the angle adjustment operation of the rotating plate 5, ensuring that the rotating plate 5 maintains a fixed angle after adjustment, and ensuring the stability of the air outlet direction of the equipment. A square hole is provided on the surface of the rotating plate 5, and a dustproof net 6 is slidably connected in the square hole of the rotating plate 5. A slidable dustproof net 6 is arranged in the square hole of the rotating plate 5, which can effectively intercept external dust and other debris, and avoid the large holes set at the traditional air outlet, granular impurities or dust It is easy to enter the interior of the unit case 1 through the hole. A threaded rod 16 is threadedly inserted on one side of the rotating plate 5. One end of the threaded rod 16 abuts against the dustproof net 6. The dustproof net 6 can be conveniently tightened or loosened by rotating the threaded rod 16, so that the dustproof net 6 can be quickly installed and disassembled, which is convenient for regular cleaning or replacement of the dustproof net 6. While ensuring the dustproof effect, the convenience of maintenance is improved. One end of the threaded rod 16 is fixedly connected to a round shaft 17, and the arc surface of the round shaft 17 is provided with a plurality of anti-slip grooves. When the dustproof net 6 needs to be adjusted, the round shaft 17 can be directly grasped for operation. Compared with directly rotating the threaded rod 16, the round shaft 17 provides a larger force application area and reduces hand pressure.The anti-slip groove further increases the friction between the hand and the round shaft 17, allowing the user to easily rotate the threaded rod 16 even in slippery conditions such as moisture or stains on the hands. Two L-shaped blocks 11 are fixedly connected to the upper surface of the dustproof net 6, and the L-shaped blocks 11 are slidingly connected to the surface of the rotating plate 5. The setting of the L-shaped blocks 11 provides precise guidance for the sliding installation and disassembly of the dustproof net 6, making the operation process smoother and reducing the risk of damage to the dustproof net 6 or affecting the dustproof effect due to improper installation.

[0021] Working principle: In the initial state, the plug rod 13 is firmly inserted into the inner wall of the slot of the fixing frame 3 under the elastic force of the spring 15, so that the rotating plate 5 maintains a fixed angle, and the air outlet discharges air in a predetermined direction and size. When the user needs to change the air outlet direction and position size, the plug rod 13 is pulled out of the slot of the fixing frame 3 by pulling the round block 14, and the rotating plate 5 can be rotated at this time. During the rotation of the rotating plate 5, the arc plate 8 is driven to move by the connecting rod 7, and the arc plate 8 drives the sliding rod 9 connected thereto to slide in the sliding hole 10, thereby adjusting the angle of the rotating plate 5. After adjusting to the appropriate angle, release the round block 14, and the elastic force of the spring 15 drives the plug rod 13 to automatically reset, firmly insert it into the corresponding slot of the fixing frame 3, fix the angle of the rotating plate 5, change the air outlet direction and position size, and accurately guide the wind to the required area. In terms of dust prevention, the dustproof net 6 in the square hole of the rotating plate 5 intercepts external dust and debris to prevent it from entering the inside of the unit box 1. When the dust screen 6 needs to be cleaned or replaced, rotate the threaded rod 16. Since one end of the threaded rod 16 is in contact with the dust screen 6, rotating the threaded rod 16 can separate it from the dust screen 6. At this time, the L-shaped block 11 fixed on the upper surface of the dust screen 6 slides along the surface of the rotating plate 5, providing precise guidance for the removal of the dust screen 6 and making the operation smooth. When installing the dust screen 6, reverse the operation, guide the dust screen 6 along the L-shaped block 11 and slide it into the square hole of the rotating plate 5, and then rotate the threaded rod 16 to tighten the dust screen 6. When operating the threaded rod 16, the round shaft 17 fixed at one end thereof and the anti-skid groove on the round shaft 17 play a role. The round shaft 17 provides a large force application area, and the anti-skid groove increases friction, making it easy for the user to easily rotate the threaded rod 16 and complete the installation and removal operations of the dust screen 6.
