When the rotating shaft rotates, it drives the lamp holder 38 at the bottom to start rotating. When the lamp holder 38 rotates, it drives the infrared light bar 37 at the bottom to start rotating, so that the light emitted by the infrared light bar 37 during heating is more uniform, avoiding local overheating and damage to the material. The lampshade 36 can concentrate the infrared rays emitted by the infrared light bar 37 on the material at the bottom, thereby improving the drying efficiency and reducing energy waste. The hot steam generated when the material is dried is discharged along the air outlet 20. The filter 40 can prevent external dust and impurities from entering the drying chamber 16 to contaminate the material. When the hot air flows through the piston chamber 42, the thermistor liquid inside it expands due to the heat, pushing the piston plate 43 to move to the outside of the air outlet 20, driving the piston rod 44 to move outward. At this time, the return spring 47 is compressed to generate an elastic force in the opposite direction; when the piston rod 44 moves outward, it drives the conductive rod 45 connected to its outer end to slide on the surface of the resistor 46, so that the part of the resistor 46 connected to the circuit increases, the resistance 46 in the circuit increases, and the power of the infrared light bar 37 decreases, so that the temperature inside the drying chamber 16 can be controlled, and the overheating protection of the material is realized to prevent the material from being affected by the excessively high heating temperature.

Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
