A drying oven is arranged on the right side of the drying oven body, and the drying oven is fixedly connected to the drying oven body. The left side of the drying oven body A main control is provided, which is electrically connected to the main body of the drying box. A supporting leg is provided at the bottom end of the main body of the drying box, which is fixedly connected to the main body of the drying box. A ventilation window is provided at the bottom left end of the drying box, which is nested and connected to the drying box. This type of intelligent drying box adopts two drying methods, wind drying and light drying, to increase the drying speed. The drying effect is achieved by accelerating the speed of air flow inside the drying box and increasing the internal temperature. It can also kill bacteria on the surface of objects and remove fine dust on the surface of objects. Four 40-watt incandescent lamps are installed inside the drying box.
