Abstract
A respiration nozzle has a hollow body with a front and a rear, at least one outlet made of a resilient membrane, and two inflatable nasal tubes. The at least one outlet is formed on the front of the hollow body and has a cross-shaped slit valve defined in the membrane to temporarily open and release air from the respiration nozzle. The two inflatable nasal tubes are formed on the rear of the hollow body and are enabled to inflate when air is pumped into the respiration nozzle. Therefore, air pressure inside the respiration nozzle is kept at a positive pressure to minimize consumption of electricity when pumping the air. Meanwhile, the inflatable nasal tubes gently and evenly match the nasal cavities without causing any uncomfortable feeling to the wearer.
