Foldable high-speed hair dryer

Abstract

A foldable high-speed hair dryer, comprising an airflow barrel (1) and a foldable handle (2) connected to the airflow barrel (1). A control circuit board (3) used to control the hair dryer is disposed within the airflow barrel (1), and a power supply module (4) used to supply power to the control circuit board (3) is disposed on a foldable section of the handle (2). That is, a conventional hair dryer circuit board is split into two parts: the power supply module (4) and the control circuit board (3). The power supply module (4) is disposed on the foldable section of the handle (2), and the control circuit board (3) is disposed within the airflow barrel (1), so that only power lines need to be routed through the folding joint, while data lines for the control portion do not require routing. This arrangement significantly reduces the number of wires that need to be routed, and the continued expansion of subsequent functions will not be restricted by wiring considerations.
