[0003]本发明的目的是提供双扇叶抽油烟机，通过双扇叶抽油烟机解决了现有技术中存在的排烟效果差的问题

Benefits of technology

[0021]1. The flow boosting device of the double-blade range hood of the present invention, in conjunction with the internal negative pressure, amplifies the flow of small-flow, high-pressure gas. Based on the influence of the viscous force between gases, it induces the outside air to accelerate. After the gas accelerates, it is injected from the flow boosting hole to stimulate the negative pressure of the inner air box, effectively expanding the area of ​​the negative pressure and increasing the flow rate. This increases the air volume entering through the fume extraction pipe, so as to achieve the effect of collecting fumes by utilizing the amplified airflow negative pressure, thereby improving the fume collection efficiency of the range hood.
