Abstract
A sensing and controlling module of airflow for an active aerosol suction device has a tube, a sensing membrane, a sensing coil, a controlling membrane, a controlling coil, and a magnetic unit. The sensing membrane is mounted in the tube. The controlling membrane is disposed at an air inlet of the tube. The sensing membrane and the controlling membrane are capable of bending deformation. The sensing coil is adhered to and spread on the surface of the sensing membrane, and the controlling coil is adhered to and spread on the surface of the controlling membrane. The magnetic unit is disposed at a spaced interval from the sensing membrane and the controlling membrane. With the sensing membrane and the controlling membrane, the sensing and controlling module is capable of sensing and controlling airflow rate.
