The utility model provides a kind of electric hair dryer, it includes shell and hair dryer piece.The electric hair dryer of the utility model, shell inside is equipped with multiple independent air duct, each air duct independently sets air inlet, air outlet and hair dryer piece, airflow can independently circulate in respective air duct inside, effectively ensure the air speed, air pressure stability of each direction air outlet, improve overall hair drying efficiency;And, the air outlet direction of the air outlet passage formed by the electric hair dryer corresponding multiple air ducts is different, so that user can realize the coverage of multiple area airflow without frequently adjusting the position of electric hair dryer, to make airflow distribution more uniform, range more extensive, to effectively cover the different area of object to be blown dry, improve user's use experience.

This invention relates to a debris removal system and method based on multimodal optical detection using air separation. The system includes a feed duct, a primary visual inspection and removal unit, a secondary laser inspection and removal unit arranged sequentially along the material conveying direction of the feed duct, a debris collection unit connected to the feed duct, and a noise reduction and maintenance unit that encloses noise-generating components. This invention forms a redundant and complementary detection system through dual-modal optical detection using both vision and laser. Primary visual inspection quickly removes debris with obvious optical characteristics, while secondary laser inspection identifies foreign objects of the same color in blind spots of visual inspection based on the physical properties of the material surface. This significantly improves the overall debris detection and removal rate, ensuring the high purity of the finished product.
