Description

Technical Field

[0001] The utility model belongs to the technical field of hair dryers and relates to a wireless portable hair dryer with replaceable batteries. Background Art

[0002] A hair dryer is a small household appliance used to dry hair. Its main components are a heating wire and a small fan. When the hair dryer is working, the motor drives the fan blades to rotate to generate high-speed airflow. The airflow is heated after passing through the heating wire and flows out through the air outlet. After the heated airflow comes into contact with the hair, it accelerates the evaporation of moisture in the hair to achieve the purpose of drying the hair. A typical hair dryer usually uses AC power to power the heating wire and fan through a power cord. Due to the limitation of the power cord, the hair dryer can only be used in a limited area. In some special places of use such as outdoors, swimming pools, and student dormitories where there is no power supply, traditional wired hair dryers cannot be used. Even in indoor places with power supply, women and children have a poor experience using wired hair dryers in fixed areas for a long time. Therefore, it is necessary to design a portable and movable hair dryer. Utility Model Content
