1. An air-cooled negative ion hair curler, comprising:
a housing of which an inner hollow structure is formed inside and an open structure is disposed at an upper end;
a driving mechanism arranged in the inner hollow structure of the housing and configured to output left and right rotational torques, wherein the driving mechanism includes a motor, a gear, a support member, and a transmission member;
a sleeve arranged at an upper end of the driving mechanism and in transmission connection with the driving mechanism, wherein the sleeve comprises an annular ring and a pair of legs protruding outwardly from the annular ring;
a heating assembly arranged above the driving mechanism and configured to generate heat for hair to be heated; and
a fan assembly arranged on one side of the housing and configured to form an airflow;
wherein,
an air supply channel is disposed in the inner hollow structure of the housing, and a negative ion airflow delivered by the fan assembly cools the hair on the heating assembly through the air supply channel.
