Today’s Patent – Air-Cooled Negative Ion Hair Curler

The said invention (US11988046B1) was invented by Wansong Ma, and patented by USPTO on October 25^th, 2023. Currently, it stands assigned to the Individual.

This utility model describes an air-cooled negative ion hair curler designed for efficient hair styling with enhanced hair protection. The hair curler includes a housing with an inner air supply channel, a driving mechanism, a heating assembly, a hair curling mechanism, and a fan assembly. As hair is curled by the heated rod, the fan directs a stream of negatively charged ions through the air channel to cool the hair quickly, setting the curl in place. This rapid cooling helps maintain the style longer while protecting the hair from prolonged heat exposure. Negative ions neutralize static, reduce frizz, and make hair smoother, enhancing the overall styling effect.

The hair curler’s design addresses limitations of conventional curlers, where negative ions tend to accumulate near the generator and fail to diffuse effectively. By positioning the negative ion generator near the fan outlet, the airflow disperses the ions directly onto the hair. The device also includes an adjustable controller that manages the heating and cooling cycles for precise temperature control, rotation, and timing, ensuring stable and controlled styling. Additional features like detachable components, geared support, and protective isolation layers increase durability and ease of maintenance, creating a reliable tool for achieving long-lasting curls with minimized heat damage.
