Abstract: Disclosed is a large-capacity essential oil nozzle where an external wall of the nozzle includes a thread base that receives the threaded mouth of a large-capacity bottle. A liquid permeable metal block connected to a metal tube extends into the bottle via a central hole in a stopper. A seal is made with a shoulder at the bottom of the threads within the thread base. Preferably, the stopper has a T-shape and the metal tube has a flange, a seal being made via an edge of the T-shaped stopper, the flange, and a sealing gasket. The nozzle may include a universal mount formed from a spring-loaded mechanism to allow the nozzle to be connected to electric blow dryers of different size. The large-capacity essential oil nozzle frees the glass bottle from being restricted by the surrounding structure, increasing the allowable volume of the glass bottle and eliminating the need for frequent changes.
