[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] Reference Figures 1-5 As shown, this embodiment provides an air outlet adjustment device for a central air conditioner, including an air outlet duct 1, a hydraulic rod 3 is installed on the side wall of the air outlet duct 1, an adjustment component is installed in the air outlet duct 1, the adjustment component is transmission-connected to the hydraulic rod 3, a plurality of blades 9 are rotatably connected to the bottom of the air outlet duct 1, the blades 9 are used to adjust the wind direction, the blades 9 are transmission-connected to a drive component, the drive component is located on the outside of the air outlet duct 1, and extension plates 4 are fixedly connected on all four sides of the bottom of the air outlet duct 1, a protective net 16 is fixedly connected to the inner wall of the extension plate 4, and a cleaning component is provided above the protective net 16, which is used to clean dust on the protective net 16.

[0023] During use, the hydraulic rod 3 is used to control the movement of the adjustment component, thereby adjusting the airflow volume of the air outlet duct 1. The driving component drives the blades 9 to rotate, thereby adjusting the direction of the air outlet. After long-term use, a certain amount of dust will accumulate on the protective net 16. The cleaning component can remove the dust from the protective net 16 to ensure the cleanliness of the protective net 16, thereby eliminating the need for manual cleaning, saving time and effort. The utility model has a simple structure and is easy to use. It can adjust the air volume of the air outlet duct 1 and the air outlet direction, is easy to operate, has strong adjustable performance, and does not require manual cleaning, saving time and effort, and is highly practical.

[0024] A further optimized solution is provided, in which the adjustment assembly includes a fixed plate 6 fixedly connected to the inner wall of the air outlet duct 1, with a movable plate 7 slidably connected to the top of the fixed plate 6. A first through-hole is provided on the fixed plate 6, and a second through-hole is provided on the movable plate 7. The first through-hole matches the second through-hole. A connecting rod 8 is fixedly connected to the side wall of the movable plate 7. The end of the connecting rod 8 away from the movable plate 7 extends out of the air outlet duct 1 and is fixedly connected to the output end of the hydraulic rod 3. The hydraulic rod 3 contracts, driving the connecting rod 8 to move, which in turn drives the movable plate 7 to move. When the movable plate 7 moves, it blocks the first through-hole, thereby reducing the air volume. When the first through-hole completely overlaps with the second through-hole, the air volume is maximized, making adjustment convenient.

[0025] In a further optimized solution, a bracket 2 is fixed to the outer wall of the air outlet pipe 1, and the hydraulic rod 3 is fixed to the inner wall of the bracket 2. The bracket 2 supports the hydraulic rod 3, facilitating the extension and contraction of the hydraulic rod 3.

[0026] Further optimizing the solution, the drive assembly includes a motor 14, the output shaft of the motor 14 is fixedly connected to the second gear 13, the second gear 13 is meshed with a double-sided toothed plate 12, the bottom of the double-sided toothed plate 12 is transmission-connected to a connecting member, and the connecting member is transmission-connected to the blades 9. The motor 14 drives the second gear 13 to rotate, the second gear 13 drives the double-sided toothed plate 12 to move, the double-sided toothed plate 12 drives the connecting member to rotate, and the connecting member drives the blades 9 to rotate, thereby adjusting the air outlet direction.

[0027] A further optimized solution is that the connecting member includes a plurality of connecting shafts 10, which are arranged in a one-to-one correspondence with the plurality of blades 9. The ends of the connecting shafts 10 pass through the air outlet pipe 1 and are fixedly connected to the blades 9. A first gear 11 is fixedly connected to the connecting shaft 10, and the first gear 11 engages with the bottom surface of the double-sided toothed plate 12. The movement of the double-sided toothed plate 12 drives the first gear 11 to rotate, the first gear 11 drives the connecting shaft 10 to rotate, and the connecting shaft 10 drives the blades 9 to rotate, thereby completing the adjustment of the air outlet direction.

[0028] In a further optimized solution, a protective box 5 is fixedly connected to the outside of the air outlet duct 1, the motor 14 is fixedly connected to the inner wall of the protective box 5, the double-sided toothed plate 12 is slidably connected to the inner wall of the protective box 5, and the connecting shaft 10 is rotatably connected to the inner wall of the protective box 5. The protective box 5 plays a supporting role and can prevent dust from entering, ensuring a good transmission effect.

[0029] A further optimized solution includes a cleaning assembly comprising electric slide rails 15 symmetrically fixed to the inner wall of the extension plate 4. A slider 17 is slidably connected between the two electric slide rails 15. A cleaning block 18 is fixed to the bottom of the slider 17. A plurality of brushes are fixed to the bottom surface of the cleaning block 18, and the brushes come into contact with the protective net 16. When cleaning is required, the electric slide rails 15 are activated, driving the slider 17 to move. The slider 17 drives the cleaning block 18 to move. The cleaning block 18 drives the brushes to move. The brushes clean the dust on the surface of the protective net 16.

[0030] To further optimize the solution, dust suction pipes 19 are fixedly connected to both sides of the cleaning block 18, with the nozzles of the dust suction pipes 19 facing the protective net 16. A dust collection box 20 is fixedly connected to the outside of the extension plate 4, and the dust collection box 20 is connected to the dust suction pipes 19 via a hose. The dust collection box 20 has a dust outlet, which is usually blocked by a sealing plate. The sealing plate can be opened when cleaning is required. When the brush cleans the protective net 16, the dust removed by the dust suction pipes 19 is sucked away to prevent a large amount of dust from falling downward. The sucked dust is then passed through the hose into the dust collection box 20 for collection. The dust collection box 20 can be cleaned regularly.
