The shutter plate 33 is slidably fitted to the nozzle inner casing 1. Specifically, the opening and closing plate 33 includes a second guide hole 33a protruding outward, the nozzle inner housing 1 is provided with a guide post (not shown) protruding outward and penetrating through the second guide hole 33a, and the opening and closing plate 33 can slide along the second guide hole 33a relative to the guide post. In this embodiment, the second guiding hole 33a is a long strip structure, and the long side thereof is disposed along the horizontal direction, and the inner width of the second guiding hole 33a is slightly larger than the outer diameter of the guiding pillar. Preferably, in the present embodiment, the guide pillar is specifically a fourth fixing pillar 108, the fourth fixing pillar 108 protrudes outward from the second guide hole 33a, and the nozzle support plate 16 and the opening and closing plate 33 share one fixing pillar, which can simplify the structure on one hand; on the other hand, the opening and closing plate 33 is restricted by the nozzle support plate 16 to prevent the opening and closing plate 33 from being separated from the fourth fixing post 108, and the connection of the opening and closing plate 33 is more stable.

Upper and lower ends of the opening and closing plate 33 are respectively in contact with the second supporting seat 14 and the first supporting seat 13, thereby restricting the movement of the opening and closing plate 33 in the up and down direction and preventing the opening and closing plate 33 from rotating about the fourth fixing post 108. For the convenience of assembly, a certain gap is left between the upper part of the open-close plate 33 and the second supporting seat 14.

The shutter plate 33 includes a first shutter plate 331 slidably fitted to the first nozzle 11 and a second shutter plate 332 slidably fitted to the second nozzle 12. The two ends of the pull rod 32 are fixed to the first opening and closing plate 331 and the second opening and closing plate 332, respectively. When the pulling plate 31 moves upward or downward, it can provide a pushing force for driving the pulling rod 32 to move toward the first air outlet portion 101 and the second air outlet portion 102 to the pulling rod 32, and then drive the first opening and closing plate 331 and the second opening and closing plate 332 to move together, and because of being limited by the fourth fixing column 108, the first opening and closing plate 331 and the second opening and closing plate 332 will move along the horizontal direction.

The first opening/closing plate 331 cooperates with the mating end surface 112a of the first nozzle 11 to form a first air outlet segment 1041 of the first air outlet duct 104. The first opening and closing plate 331 includes an arc-shaped first air guiding surface 3311 and a second air guiding surface 3312 parallel to the end surface 112a of the mating portion, and when the first opening and closing plate 331 moves toward the first air outlet portion 101, the second air guiding surface 3312 can abut against the end surface 112a of the mating portion, so as to block the second air outlet section 1042. Preferably, the second wind guide surface 3312 and the fitting portion end surface 112a are flat surfaces, so that they can be easily molded and can be easily attached to each other. In other embodiments, as shown in fig. 7, the mating portion end surface 112a is inclined inward along the direction from the second air outlet end 20 to the first air outlet end 10, and compared with a planar structure, the inclined surface structure can effectively reduce the blockage of the mating portion end surface 112a to the air flow, so that the air flow flows out more smoothly. The second air guide surface 3312 and the end surface 112a of the fitting portion may be other surfaces that are bonded to each other, and the present invention is not limited thereto.

The second opening and closing plate 332 and the guiding portion 1231 of the air guiding plate 123 cooperate to form the third air outlet section 1051 of the second air outlet channel 105. The second opening and closing plate 332 includes the curved third air guide surface 3321, the curved direction of the third air guide surface 3321 is the same as or substantially the same as the inclined direction of the guide portion 1231, and the third air outlet section 1051 can increase the air outlet angle of the fourth air outlet section 1052. When the second shutter plate 332 moves toward the second air outlet portion 102, the third air guide surface 3321 can contact the guide portion 1231, thereby blocking the fourth air outlet section 1052.

The driving assembly 3b is disposed on the second supporting seat 14, and the driving assembly 3b includes a first driving member 35 and a rotary table 36 mounted on a first output shaft 351 of the first driving member 35. The first drive member 35 is embodied as a motor. The driving lever 361 is disposed at a position of the end surface of the rotary plate 36 near the outer side, and the driving lever 361 is inserted into the first guiding hole 3121 of the pulling plate 31. When the rotary disc 36 rotates, the shift lever 361 can rotate with the rotary disc 36, thereby driving the pulling plate 31 to move up and down.

The working principle of the diffused air switching assembly of the nozzle assembly is as follows: when the fan is started, airflow is blown out from the first air outlet duct 104 or the second air outlet duct 105, when the airflow direction needs to be switched, the first driving piece 35 is opened, the first driving piece 35 rotates and drives the rotary disc 36 to synchronously rotate, the driving lever 361 on the rotary disc 36 rotates and drives the pull plate 31 to move upwards or downwards, the pull plate 31 moves up and down and is converted into the pull rod 32 to move towards the first air outlet 104a or the second air outlet 105a, and when the pull rod moves towards the first air outlet 104a, the first opening and closing plate 331 can close the first air outlet duct 104, so that the airflow is blown out from the second air outlet duct 105; when the draw bar 32 moves toward the second outlet 105a, the second shutter plate 332 can close the second outlet duct 105, so that wind is blown out from the first outlet duct 104.
