Embodiment Construction
[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] as attached figure 1 As shown, the present invention provides an air intake device that generates high-response wide-spectrum pulsating airflow. The air intake device includes an air intake pipe 5, an air intake unit and a pulsation unit.
[0022] In the air intake unit, the fan 1 operates to provide airflow to the air intake pipe 5, and the air intake pipe 5 is installed with a flow equalizer I2 and a pulsation generator 3. In the air intake unit, the distance between the fan and the flow equalizer I2 is far enough, and the airflow reaching the flow equalizer I2 is smooth and uniform. The flow equalizer I2 is used to further eliminate the lateral airflow and ensure the smooth and uniform airflow entering the pulsation unit. The surface of flow equalizer I2 is uniformly and densely distributed with honeycomb holes with a diameter of 1.5mm.
