Hair curler and hair curling method of hair curler

The invention belongs to the technical field of hair curlers, and particularly relates to a hair curler and a hair curling method of the hair curler. Partial hair is placed in the U-shaped groove in the upper end of the curling iron, the hair forking device is driven to rotate, and the hair forking device conducts circular motion around the curling iron, so that the hair is wound on the outer side face of the curling iron. The heating piece and the fan are started, and airflow generated by the fan heats the piece to form hot airflow; the hot air flow enters the second containing cavity of the curling iron, passes through the ventilation groove of the curling iron and then is blown to the periphery of the curling iron, 360-DEG C surrounding type blowing is formed, and hair on the outer side face of the curling iron is shaped. After shaping is finished, the heating piece is turned off, the draught fan keeps working, hot air flow blown out of the curling iron is converted into cold air flow, and due to the fact
