Maintenance device for central air conditioner

The maintenance device is characterized in that a cleaning mechanism comprises a rotating rod and a driving motor, the outer surface of the driving motor is fixedly connected with the interior of a cleaning box in a penetrating mode, the output end of the driving motor is rotatably connected with the inner surface of a cleaning cavity, and the output end of the driving motor is fixedly connected with a driving rod through a coupler; the utility model relates to the technical field of central air conditioners. According to the maintenance device for the central air conditioner, the cleaning mechanism is arranged, a driving motor drives a driving gear and a cleaning plate to rotate through a driving rod, bristles on the rotating surface of the cleaning plate clean impurities on the surface of a filter plate, and meanwhile the driving gear drives a rotating gear to rotate through a transmission gear, so that a rotating rod drives a rotating roller to rotate; through the combination of the structure, the problem
