The high-performance smart hair curler is designed to enhance the curling process by integrating advanced components such as a curling assembly, heating passage, handle, hollow connecting base, hollow cylindrical heating member, blowing component, and drive motor. The curling assembly is positioned around the heating passage, with the hollow connecting base linking the handle and the heating passage. Inside the handle, the hollow cylindrical heating member and blowing component are sequentially arranged, featuring an air guide gap. The drive motor, located within the hollow cylindrical heating member, connects to the curling assembly to facilitate rotation around the heating passage.
Traditional hair curlers consist of a handle and heating roller, often controlled by a circuit panel and using materials like tourmaline ceramic for even heat distribution. However, prior designs, such as those in Chinese Patent Application No. 202410035266.3, faced issues with motor placement inside the hot air discharge passage, leading to overheating and reduced reliability. Additionally, the lack of thermal energy storage resulted in high heat loss and poor styling effects, as well as safety risks due to high surface temperatures.
The smart hair curler addresses these issues by incorporating a heat storage core within the heating passage to retain thermal energy. A hot air introducing channel runs through this core, connecting to the air guide gap, and multiple air outlet holes are evenly distributed along the heating passage. These features ensure efficient heat distribution and minimize heat loss, enhancing the curling effect while improving safety and reliability.
The curler includes a curling housing with a hair inlet and a connection to the hollow connecting base, encapsulating the curling assembly and heating passage. The curling assembly itself comprises a hair selector sleeve and sleeve ring, facilitating rotation around the heating passage. A drive gear set, including a driving and driven gear, ensures precise movement, while a stop sleeve prevents hair from entering the connecting base. Air guide ports on the connecting and stop sleeves further optimize airflow.
The hollow cylindrical heating member consists of an outer and inner sleeve, with heating wires arranged between them and a heat-insulating sleeve on the outside. This configuration creates an air guide gap, with the blowing component located at the rear of the heat-insulating sleeve and the drive motor secured within the inner sleeve. These elements work together to deliver a high-performance, efficient, and safe hair curling experience.
