The structure 10 and the refrigeration mechanism 15 are both commonly used temperature control devices for cooling and heating fans. When adjusting the cooling and heating, the above devices cooperate with each other to form a rotating structure for switching between cooling and heating. The elastic connecting plate 12 is forced to shrink, which reduces the operating space of the rotating mechanism. The mounting block 5 can effectively avoid the hidden dangers of mutual influence between the cooling and heating modules. The mounting block 5 enters the interior of the fan housing 1 through the passage opening 6.
