  • Patent number: 11882871
    Abstract: A detachable atomizing device and a container thereof are provided. The container is detachably assembled to an atomizing assembly. The container includes a cup and a flexible film. The cup has an opening arranged at an end thereof, the flexible film covers the opening of the cup, and the flexible film has a tension region and an outer ring-shaped region that surrounds the tension region. The tension region has a plurality of atomizing holes having an average diameter within a range of 1 ?m to 20 ?m, and the outer ring-shaped region is attached to the cup. When the cup is assembled to the atomizing assembly, a tension value of the tension region of the flexible film is increased from an initial tension value to an atomizing tension value by being pressed from the atomizing assembly, and the atomizing holes of the tension region are configured to allow liquid to pass there-through and to be formed as aerosol mist having an average atomized particle diameter less than a predetermined value.

  • Publication number: 20210128854
    Abstract: A method and a circuit system for driving a nebulizer are provided. When the nebulizer receives acoustic waves, a control circuit extracts audio signals from the acoustic waves. Afterwards, the control circuit determines if the audio signals are within a predetermined frequency range, and can determine whether or not to drive a circuit to produce an aerosol based on the audio signals. Further, a volume of the acoustic waves can also be used to determine whether or not to produce the aerosol, and also determine an output rate of the aerosol. The circuit system of the nebulizer includes an audio receiver for receiving the acoustic waves, an aerosol generator for producing the aerosol, and the control circuit used to control a driving circuit of the aerosol generator to drive a vibrational element to produce the aerosol through vibration in response to the audio signals and the volume.
