Moreover, the rib 4321 forming the second limiting groove 4321a can limit the second root shaft 85, and the second root shaft 85 can only reciprocate in the second limiting groove 4321a under the blocking of the rib 4321.

The decorative plate 412 of the first fixing member 41 is embedded into the inner side of the limit edge 612 of the first rotating portion 61 of the knob 60, meanwhile, the positioning column 4121 on the decorative plate 412 passes through the positioning hole 61a of the knob 60 to be clamped in the limit hole 212b on the flange 212, the convex ring 414 of the first fixing member 41 passes through the central mounting hole 212a to extend into the mounting cavity, and the second rotating portion 63 of the knob 60 is sleeved outside the convex ring 414.

When the angle of the guide vane 80 needs to be adjusted, the user can rotate the knob 60, the rotating groove 63a of the knob 60 drives the first root shaft 83 of the guide vane 80 to move in the second limiting groove 4321a, and at this time, the position of the second root shaft 85 in the circumferential direction is kept unchanged under the limiting action of the first limiting groove 414a, so that the relative axial angle between the guide vane 80 and the front net assembly 20 can be changed, and the user can adjust the blowing range and the wind sense according to the needs. When the air guiding structure 100 needs to be cleaned, the air guiding structure 100 can be cleaned as a whole, or each component can be cleaned independently after being disassembled.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
