AI Technical Summary
Traditional blower heads suffer from uneven airflow distribution, poor performance, and high energy consumption, making it difficult to meet the demands of modern industry and daily life for efficient and energy-saving equipment.
A blower head for a blower/suction fan was designed. Through the combination of inner and outer pipes and valve ports, combined with a blower/suction control mechanism, the blower can freely switch between blowing and suction and achieve uniform distribution of airflow. The airflow direction is controlled by opening and closing the first and second valve ports, and the airflow uniformity is improved by combining a filter screen and a guide screen.
This achieves a uniform distribution of blowing and suction effects in the blower, reduces energy consumption, increases equipment lifespan and working efficiency, and meets the needs of high efficiency and energy saving.
