Example 2

The difference between this embodiment and the above-mentioned embodiment is that, as shown in FIG. 7 , the supporting plate 2 of this embodiment is provided with two rotating shafts 3 , that is, one rotating shaft 3 is provided at each of the left and right ends of the supporting plate 2 . Before cleaning the air duct, lift the support plate 2 so that the snap button 4 is separated from the button hole 7, and the positioning block 5 is separated from the positioning hole 8. Rotation, such an arrangement enables more operation options when rotating the wind guide vane assembly, reduces the interference to other components when rotating the wind guide vane assembly, and meets the requirements of the actual operating environment.

Example 3

The difference between this embodiment and the above-mentioned embodiment is that, as shown in FIG. 8 , the connecting rod 9 of this embodiment is divided into two separate parts, namely the first connecting rod 91 and the second connecting rod 92 , and the wind guide vane assembly. It is also divided into two parts corresponding to it.

Specifically, the support plate 2 includes a first support plate 21 on the left and a second support plate 22 on the right. The first support plate 21 and the second support plate 22 are both provided with a rotating shaft 3 , an elastic buckle 4 and a positioning block 5 , the positions of the rotating shaft 3, the elastic buckle 4 and the positioning block 5 are selected according to the scheme of the above-mentioned embodiment; the number of the rotating shaft 3 and the elastic buckle 4 is selected according to the scheme of the above-mentioned embodiment. Before cleaning the air duct, lift up the first support plate 21 and the second support plate 22 so that the snap button 4 is separated from the button hole 7 and the positioning block 5 is separated from the positioning hole 8, depending on the rotation between the shaft 3 and the shaft hole 6 The rotation of the air guide vane assembly is realized.

The air duct is opened through the rotation of the air guide vane assembly, which is convenient for cleaning the air duct. When cleaning the position, it is only necessary to rotate the air guide blade assembly at the corresponding position. For example, when cleaning the left half of the air duct, lift the first support plate 21, the elastic buckle 4 is separated from the button hole 7, and the positioning block 5 is connected to the positioning block 5. The holes 8 are separated, and the effective cleaning process of the air duct can be realized without operating the second support plate 22; at the same time, the connecting rod 9 and the support plate 2 are respectively arranged as two separate parts, that is, the connecting rod 9 includes a separate first connection The rod 91 and the second connecting rod 92, the support plate 2 is separated into the first support plate 21 and the second support plate 22, and this arrangement makes the turning radii of the first support plate 21 and the second support plate 22 compared with the above-mentioned embodiment. The turning radius is smaller, which reduces the interference to other components when turning the wind guide vane assembly, and meets the needs of the actual operating environment.

It should be noted that when the first support plate 21 and the second support plate are each provided with a rotating shaft 3, the two rotating shafts 3 are located at the relatively close ends or opposite ends of the first support plate 21 and the second support plate 22, respectively. The far ends, wherein the relatively far ends refer to the leftmost of the first support plate 21 and the rightmost of the second support plate 22, and the relatively close ends refer to the rightmost and the second of the first support plate 21 The leftmost end of the support plate 22 . Such an arrangement enables a larger operating space and more operation options when cleaning the blades, and the blades can be cleaned to the greatest extent.

In this embodiment, by dividing the air guide vane assembly into two parts corresponding to the separate connecting rods 9, when cleaning different positions of the air duct, it is only necessary to rotate the air guide vane assembly at the corresponding position, thereby reducing the number of rotating air guide vanes. Interference with other components during assembly to meet the requirements of the actual operating environment.
