  • Patent number: 11819604
    Abstract: A breathing airflow detecting device for a nebulizing device is disclosed. The breathing airflow detecting device includes a case, wherein a light switching module and a light blocking element are arranged in the case. The light blocking element is arranged between optical routes of a light emitting element and a light receiving element. When airflow from an inlet blows and swings the light blocking element, the light blocking element blocks light or passes light to the light receiving element. When the light receiving element detects the variation of light, the light receiving element emits a signal from the output port of the light switching module to drive or stop driving a nebulizing device. As a result, when a patient breathes, the nebulizing device is driven such that the volume of the nebulized medicine is accurately inhaled into the patient's lungs.
