1. An air guiding device comprising:
at least one air guiding part configured to guide airflow blown out of an air outlet of an air-conditioning system, the at least one air guiding part being configured to rotate from a first angle to a second angle to change a guiding direction of the airflow from a first direction to a second direction; and
a flow straightening grid provided on at least one of an upstream side and a downstream side of the at least one air guiding part,
wherein the flow straightening grid is configured to rotate together with the at least one air guiding part between the first angle and the second angle such that when the flow straightening grid is rotated to the first angle with the at least one air guiding part, the flow straightening grid straightens the airflow in the first direction and when the flow straightening grid is rotated to the second angle with the at least one air guiding part, the flow straightening grid straightens the airflow in the second direction;
wherein an end cap is fitted over each of two ends of the at least one air guiding part in a length direction of the air outlet, a mounting space is defined in the end cap, and an air-guide-part drive device for driving the at least one air guiding part to rotate is arranged in the mounting space; and
wherein the end cap is provided with an avoidance notch for avoiding the air-guide-part drive device when rotating together with the air guiding part.
