Core Structure Components
Heating Element: Typically uses a nichrome alloy resistance wire (such as 2080 nichrome wire), wound on a ceramic or mica frame. Some industrial models use a detachable heating core for easy maintenance.
Fan System: Mostly miniature DC or AC blowers; some high-end models use brushless motors with a lifespan of 10,000–30,000 hours, providing stable airflow (common airflow range: 120–650 L/min).
Temperature Control System: Includes K-type thermocouples or built-in temperature sensors and control circuits (such as PID/SSR controllers), enabling precise temperature control (accuracy up to ±1°C). Some models support digital display.
Gun Body and Handle: Made of heat-resistant engineering plastics (temperature resistant up to 300°C). Some industrial models use stainless steel tubes with quartz insulation tubes, supporting continuous operation.
Airflow Stabilizer/Nozzle: Ensures direct and uniform heating airflow, avoiding turbulence that affects efficiency.
Special Design Features:
Replaceable Heating Core and Nozzle: Facilitates maintenance and adapts to different operational needs.
Reed Switch Magnetic Sleep Switch: Automatically powers off when placed on a stand, enhancing safety.
Dry-Burn Protection: Automatically cuts off power when airflow is insufficient, preventing the heating wire from burning out.
Direction Sensor: Some smart models detect the handle angle to determine the operating status (working/standby/off).
