Abstract

A related switching power supply with an accessory protection function comprises a shell and a front cover, a through hole is formed in the top of the shell, a sleeve plate is fixed in the through hole, a movable groove is formed in the top of the sleeve plate in a penetrating mode, a limiting groove is formed in the inner wall of one side of the movable groove, and a limiting block is slidably connected in the limiting groove; a limiting spring is fixedly connected between the limiting block and the inner wall of the limiting groove, a heat removal column is fixedly connected to the inner side of the limiting block, a heat removal groove is formed in one side of the heat removal column, a heat conduction groove is formed in the bottom of the heat removal column and communicates with the heat removal groove, a mounting shaft is rotationally connected to the outlet position of the heat removal groove, and first fan blades are fixedly connected to the top of the mounting shaft; and second fan blades are fixedly connected to the bottom of the mounting shaft, and the edges of the first fan blades and the second fan blades are tangent to the inner wall of the heat removal groove According to the invention, hot air flow emitted during working of components is utilized to push the outlets of the heat removal grooves in the heat removal columns to the upper part of the movable grooves, and the first fan blades and the second fan blades are pushed to rotate, so that the effects of heat dissipation and dust removal are achieved.

Description

technical field [0001] The invention relates to the technical field of switching power supplies, in particular to a switching power supply with accessory protection function. Background technique [0002] Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. Switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. With the development and innovation of power electronics technology, switching power supply technology is constantly innovating. Switching power supply is widely used in almost all electronic devices due to its small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of today's electronic information industry. [0003] When the switching power supply is in use, due to the different environments and the self-heating of the switching power su...
