This utility model relates to the field of electromagnetic shielding door technology and discloses a manual electromagnetic shielding door, including a door frame, a door leaf located in the middle of the front side of the door frame, a locking device located at the top of the left front end of the door frame, an upper locking rod located at the left front end of the door leaf, a limit seat located on the bottom left side of the upper locking rod, a lower locking rod rotatably connected to the bottom of the limit seat, a connecting piece rotatably connected to the bottom end of the lower locking rod, and a drive shaft rotatably connected to the inner side of the connecting piece. In this utility model, the locking device and hinge device are installed on the vertical beam of the shielding door frame, and the locking head fixed wheel moves in a triangular pattern to achieve the purpose of opening and locking. Therefore, the manual locking electromagnetic shielding door does not affect its effectiveness in the absence of power or power outages, has strong locking force, high stability, low maintenance costs, high safety protection performance, is not affected by voltage instability and power outages, and improves usage efficiency.

The application provides a self-cleaning method of a surface cleaning system, the surface cleaning system comprising a surface cleaning device provided with a wiping member and a cleaning assembly provided with a cleaning tank for accommodating the wiping member and cleaning liquid and a dirt collecting cavity, the surface cleaning system being provided with a sound emitting device, the self-cleaning method comprising: docking the surface cleaning device and the cleaning assembly in place so that the wiping member is located in the cleaning tank; rotating the wiping member in the cleaning tank for cleaning; operating the sound emitting device and reducing the rotating speed of the wiping member to a preset rotating speed n, the preset rotating speed n being smaller than any rotating speed in the cleaning step, so that the cleaning sound of the wiping member does not cover the sound of the sound emitting device, and the user cannot timely drain the sewage, so that the wiping member cannot be scraped dry.
