The proposed device, Diode Laser, is a surgical device intended for hair removal, permanent hair reduction on all skin types (Fitzpatrick skin type I-VI). The power system includes a network power supply, laser power supply system, refrigeration power supply system, and auxiliary power supply system. The power lines and rocker switch control the on-off of the hair removal instrument with the outside power supply. The key switch and emergency stop switch control the on-off of network power, providing work current for the microprocessor control system, touch screen operation display system, and other functional components. The power system has a self-protection function, notifying users through the touch screen interface in case of errors. The microprocessor control system automates the operation, performing self-checks and calling treatment parameters. The operation display system consists of a touch screen, indicator, and buzzer, allowing the operator to control the microprocessor and monitor the device state and parameters.
