A switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. With the development and innovation of power electronics technology, switching power supply technology is also constantly innovating. At present, switching power supplies are widely used in almost all electronic devices and are an indispensable power supply method for the rapid development of today's electronic information industry.

The movable cover is movably connected to the front of the storage bin, and the inner middle of the movable cover is movably connected to a driving wheel. The inner part of the movable cover is movably connected to a fastening bolt, and the other side of the front of the protection component as a whole is fixedly connected to the protective shell. The protection shell is arranged in this way so that when the user operates the protection component as a whole, the power switch of the device can be controlled through the coil box inside the protective shell, so that when the user manually operates the protection component as a whole, there is no risk of electric shock due to water on the hands, which reflects the practicality of the device and can have broad development prospects in the future.
