Ultrasonic Nicotine Mist Inhaler for Leak-Free Consistent Dosing

The patent replaces the thermal heating system with an ultrasonic vibration system. The ultrasonic transducer generates high-frequency mechanical vibrations that directly atomize the liquid through cavitation and mechanical stress, eliminating the need for high-temperature heating elements and thus preventing metal burning and burnt liquid inhalation.

The patent utilizes the phase transition of liquid to aerosol through ultrasonic cavitation rather than thermal vaporization. The ultrasonic energy creates micro-bubbles that collapse and fragment the liquid into fine droplets, achieving aerosol generation through mechanical phase transition instead of thermal phase transition.

The patent removes the membrane component entirely from the system. Instead of using a membrane to hold and deliver liquid, the design employs direct capillary wicking material that absorbs and transports liquid through capillary action, eliminating the interface where leakage occurs between membrane and mouthpiece.

The patent introduces capillary wicking material as an intermediary between the liquid reservoir and the ultrasonic transducer. This wicking material absorbs liquid and transports it through capillary forces, providing controlled liquid delivery without the leakage problems associated with membrane-based systems.

The patent replaces thermal heating with ultrasonic mechanical vibration for liquid atomization. This substitution provides more precise and consistent liquid delivery because ultrasonic vibration directly breaks liquid into uniform droplets through mechanical cavitation, avoiding the variability inherent in thermal heating processes.

The patent employs ultrasonic mechanical vibration at high frequency to atomize the liquid. The consistent high-frequency vibrations produce uniform droplet sizes and consistent dosing, as the mechanical energy is distributed evenly throughout the liquid contact area of the ultrasonic transducer.
