Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0050] The following is combined with Figures 1 to 10 The air conditioning inlet guide device according to the first aspect of the present utility model includes a housing 1, a horizontal grille 2, a vertical grille 3, an air inlet 5 on the housing 1, the vertical grille 3 being disposed inside the air inlet 5 and connected to the inner side wall of the air inlet 5, and the horizontal grille 2 being disposed inside the housing 1.

[0051] The horizontal grid 2 includes multiple grid blades 22 and a grid frame. The first side of each grid blade 22 is rotatably connected to the grid frame, and the second side of each grid blade 22 is rotatably connected to the vertical grid 3 or the housing 1. The grid frame is movably connected inside the housing 1. Multiple grids are equally spaced, and multiple grid blades 22 are located between the grid frame and the horizontal grid 2. Each grid blade 22 is perpendicular to the vertical grid 3. Multiple grid blades 22 are equally spaced.

[0052] In the above embodiments, it should be noted that the first side and the second side of each grille blade 22 are opposite sides, and multiple grille blades 22 are equally spaced. The width of each grille blade 22 is greater than the width of the air inlet 5. The multiple grille blades 22 are parallel to each other. When the second side of the grille blade 22 is connected to the housing 1, the second side of the grille blade 22 is connected to the inner side wall of the housing 1 where the air inlet 5 is located. For example, when the air inlet 5 is opened on the bottom wall of the housing 1, the second side of each grille blade 22 is rotatably connected to the bottom wall of the housing 1 or the longitudinal grille 3.

[0054] The technical effects achieved by the above embodiments are as follows: By rotatably connecting the first side of each grille blade 22 to the grille frame and rotatably connecting the second side of each grille blade 22 to the longitudinal grille 3 or the housing 1, the user can adjust the rotation angle of multiple grille blades 22 according to their needs. In this way, the direction and angle of the grille blades 22 can be adjusted according to the required air volume and air guiding angle. This achieves flexible airflow guidance of the air inlet 5 of the air conditioner at the top air outlet, avoiding airflow backflow. Even in complex indoor environments, by adjusting the direction and angle of the grille blades 22, the airflow rebound caused by furniture can be avoided, thus preventing the air conditioner from exacerbating airflow backflow. This ensures the cooling and heating efficiency of the air conditioner, prevents uneven indoor temperature, and avoids accelerated wear of the core components of the equipment.

In addition, due to the setting of the elongated hole 214, the moving shaft 235 drives the lifting connecting block 213 to move more conveniently and reliably. Furthermore, due to the cooperation of multiple grille blades 22, the lifting connecting block 213 and the beam rod 211 can move according to the corresponding trajectory, ensuring the reliability of the adjustment of the rotation angle of the grille blades 22.
