The invention relates to a cooling and heating fan which comprises a shell, a fan body and a fan cover. The fan blade assembly is rotatably arranged in the air duct; the heating piece is arranged in the air duct and is spaced from the fan blade assembly in the air outlet direction; the wind shielding piece is movably arranged relative to the shell; wherein the air inlet comprises a first air opening and a second air opening, and the heating piece corresponds to the second air opening in the air outlet direction; the windshield has a warm air position and a cold air position. The air blocking piece can provide a large air inlet area at the cold air position, the air outlet amount is increased, the first air opening is blocked at the warm air position, airflow is heated by the heating piece at the second air opening to form warm air, at the moment, the probability that the warm air effect is affected due to exchange of cold air and hot air in the air channel can be reduced, and the heating efficiency is improved. And the warm air temperature is more stable.
