[0002] The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as housing, transformer, inductor, capacitor, control IC, PCB board, etc. Its working principle is to convert AC input into DC output; according to the connection method, it can be divided into wall-mounted and desktop types. It is widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment;

[0003] After searching, the Chinese patent number is CN217362191U, which includes a box body, a protective box is fixedly connected to the inner wall of the box body, a carrying plate is arranged inside the protective box, a mounting groove is opened on the upper surface of the carrying plate, a monitoring power supply is installed inside the mounting groove, a through hole is opened on the inner wall of the mounting groove, a buffer mechanism is arranged on the lower surface of the carrying plate, a heat dissipation mechanism is arranged on the inner side wall of the box body, a second heat dissipation hole is opened on the lower surface of the protective box, and a secondary filter is fixedly connected to the inner wall of the second heat dissipation hole. During use, the monitoring power supply can be dissipated while preventing dust from entering the inside of the monitoring power supply, thereby effectively protecting the monitoring power supply and extending the service life of the monitoring power supply. Secondly, the monitoring power supply can be damped to avoid damage caused by bumps during transportation. However, there is a phenomenon that the monitoring power supply and the inner wall of the protective box will interfere with each other due to bumps during transportation, which will cause the monitoring power supply shell to be damaged. Finally, the monitoring power supply does not realize the protection function during transportation, and in the process of heat dissipation of the box body that is repeatedly used during transportation, the primary filter will have a long-term reduced function. For this reason, we propose a monitoring power supply heat dissipation device. Utility Model Content
