Technical Field

[0001] The present invention relates to the field of hair styling appliances, and particularly to an air outlet direction switcher for a hair curler. Background Art

[0002] Currently, in the existing technology, the change direction of the air outlet airflow of a hair curling dryer is achieved by rotating an inner cylinder driven by a knob, so that the sealing member on the inner cylinder switches positions. For example, in the utility model patent with the Chinese patent application number CN2023236663312, this invention mainly drives the inner cylinder by a knob to rotate the inner cylinder, so that the sealing member switches between the first position and the second position. When the sealing member is in the first position, the air outlet direction of the air outlet is counterclockwise, and when the sealing member is in the second position, the air outlet direction of the air outlet is clockwise. The switching of this air outlet direction requires the cooperation of the air outlet structure of the outer cylinder to achieve the wind direction switching. For example, it is necessary to provide an extension plate and an arc-shaped side wall on the outer cylinder for guiding the wind, resulting in the complication of the structure of the hair curling dryer adopting this wind direction switching structure and increasing the manufacturing cost.
