Large-Capacity Blow Dryer Nozzle For Essential Oil With Universal Attachment Feature

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.

What is claimed is: 
     
         1 . An essential oil nozzle for adding essential oil to air moving through the nozzle from an output of an electric blow dryer comprising:
 a nozzle defining an air duct extending from an input end to an output end, the nozzle having wall and a connection base having internal threads and an aperture that extends through the wall into the air duct;   a bottle with an interior for containing essential oil and a mouth defined by a neck, the neck having external threads;   a stopper with a main body inserted into the mouth of the bottle and a center hole; and   a liquid permeable metal block connected to a metal tube, the metal tube inserted through the center hole of the stopper and into the bottle such that the liquid permeable metal block extends from the stopper via the metal tube and such that the metal tube is in liquid communication with the interior of the bottle to transport essential oil from the interior of the bottle to the liquid permeable metal block via the metal tube; and   wherein the bottle is connected to the thread base by threading the external threads on the neck of the bottle to the internal threads on the thread base of the nozzle, the liquid permeable metal block that extends from the stopper extending through the aperture and into the air duct of the nozzle such that air moving through the nozzle draws essential oil from the liquid permeable metal block.   
     
     
         2 . The essential oil nozzle of  claim 1  further comprising:
 a spring-loaded mechanism at an input end of the nozzle for securely attaching the input end of the nozzle to electric blow dryers with outputs of different diameter. 
 
     
     
         3 . The essential oil nozzle of  claim 1  further comprising:
 a shoulder located between the internal threads and the aperture of the connection base; and 
 a sealing gasket that is compressed against the shoulder when the bottle is threaded into the connection base. 
 
     
     
         4 . The essential oil nozzle of  claim 3  further comprising:
 a stopper flange at the end of the stopper's main body such that the stopper has a “T” shape when viewed in profile from the side; and 
 an annular flange on the metal tube; 
 wherein the neck of the bottle presses against the stopper flange, which in turn presses against the annular flange of the metal tube, which in turn presses against the sealing gasket, when the bottle is screwed into the connection base. 
 
     
     
         5 . The essential oil nozzle of  claim 1  wherein the spring-loaded mechanism for securely attaching the input end of the nozzle to electric blow dryers with outputs of different diameter comprises:
 an annular base; 
 a plurality of flexible vanes extending radially inward from the annular base; and 
 a compression element surrounding the flexible vanes for constricting the flexible vanes inward. 
 
     
     
         6 . The essential oil nozzle of  claim 5  wherein the compression element comprises a spring. 
     
     
         7 . The essential oil nozzle of  claim 5  wherein the compression element comprises an elastic band. 
     
     
         8 . The essential oil nozzle of  claim 5  wherein the compression element comprises a spring and an elastic band, wherein the plurality of flexible vanes comprising nine flexible vanes including three of a first vane type, three of second vane type, and three of a third vane type, and wherein each vane of the first vane type includes a hook for retaining the spring, and wherein each vane of the second vane type includes a hook for retaining the elastic band. 
     
     
         9 . An essential oil nozzle for adding essential oil to air moving through the nozzle from an output of an electric blow dryer comprising:
 a nozzle defining an air duct extending from an input end to an output end, the nozzle having wall and a connection base having internal threads and an aperture that extends through the wall into the air duct;   a bottle with an interior for containing essential oil and a mouth defined by a neck, the neck having external threads;   a stopper with a main body inserted into the mouth of the bottle and a center hole; and   a liquid permeable metal block connected to a metal tube, the metal tube inserted through the center hole of the stopper and into the bottle such that the liquid permeable metal block extends from the stopper via the metal tube and such that the metal tube is in liquid communication with the interior of the bottle to transport essential oil from the interior of the bottle to the liquid permeable metal block via the metal tube;   wherein the bottle is connected to the thread base by threading the external threads on the neck of the bottle to the internal threads on the thread base of the nozzle, the liquid permeable metal block that extends from the stopper extending through the aperture and into the air duct of the nozzle such that air moving through the nozzle draws essential oil from the liquid permeable metal block; and   wherein the input end of the nozzle includes a spring-loaded mechanism for securely attaching the input end of the nozzle to electric blow dryers with outputs of different diameter.   
     
     
         10 . The essential oil nozzle of  claim 9  further comprising:
 a shoulder located between the internal threads and the aperture of the connection base; and 
 a sealing gasket that is compressed against the shoulder when the bottle is threaded into the connection base. 
 
     
     
         11 . The essential oil nozzle of  claim 10  further comprising:
 a stopper flange at the end of the stopper's main body such that the stopper has a “T” shape when viewed in profile from the side; and 
 an annular flange on the metal tube; 
 wherein the neck of the bottle presses against the stopper flange, which in turn presses against the annular flange of the metal tube, which in turn presses against the sealing gasket, when the bottle is screwed into the connection base. 
 
     
     
         12 . The essential oil nozzle of  claim 9  wherein the spring-loaded mechanism for securely attaching the input end of the nozzle to electric blow dryers with outputs of different diameter comprises:
