[0055] In this embodiment, the air outlet mechanism and the fan using it have an interactive panel 112 located at one end of the main unit housing 11 of the main unit-air inlet assembly 1. When the air guide-air outlet assembly 2 swings in the pitch direction, the interactive panel 112 remains stationary, so that the interactive panel 112 can always face the user and is not affected by the movement of the air guide-air outlet assembly 2, thereby improving the convenience of the user when operating the interactive panel 112.

[0056] Furthermore, in this embodiment, the air outlet mechanism has an interactive panel 112 located at one end of the main unit housing 11 of the main unit-air intake assembly 1, which makes the interactive panel 112 closer to the installation position of the fan device 12, thereby shortening the cable routing distance (whether it is a power line or a data line).
