Aromatic nebulizing diffuser

Abstract

An aromatic nebulizing diffuser includes a base panel, a holder defining therein an oscillation chamber, a power switch, an electric fan, a fluid container, an ultrasonic oscillator, a fluid intake control device set in between the oscillation chamber and the fluid container, a dip tube in communication between the oscillation chamber and the fluid container and changeable between an open status and a close status to control the fluid intake control device in closing/opening the passage between the oscillation chamber and the fluid container, an outer housing, an air passage in air communication between the oscillation chamber and the cover for the passing of currents of air caused by the electric fan, an exhaust passage for guiding a generated fine mist of aromatic fluid droplets out of the oscillation chamber into the atmosphere.

1 . An aromatic nebulizing diffuser, comprising:
 a base panel;   a power switch mounted on said base panel;   an electric fan mounted on said base panel and electrically connected to and controllable by said power switch;   a holder comprising a transverse partition board, said transverse partition board dividing said holder into an upper part and a lower part, a center opening cut through said transverse partition board, said upper part defining therein an oscillation chamber, said lower part defining a cover, and an air passage set in air communication between the space inside said cover and said oscillation chamber to provide a path for delivering air currents caused by said electric fan;   a fluid container mounted in said holder, said fluid container comprising a container body, a container base fastened to a bottom side of said container body and defining with said container body a fluid storage chamber and an exhaust passage in air communication between said oscillation chamber and the atmosphere for exhaust of a mist of aromatic fluid droplets out of said oscillation chamber;   an ultrasonic oscillator mounted in the opening of said holder and electrically connected to said power switch;   a fluid intake control device mounted in a bottom side of said fluid container and selectively set between an open status and a close status to control delivery of a fluid from said fluid storage chamber to said oscillation chamber; and   a dip tube set in said fluid container and said oscillation chamber to communicate said fluid storage chamber and said oscillation chamber.   
     
     
         2 . The aromatic nebulizing diffuser as claimed in  claim 1 , further comprising an outer housing surrounding said fluid container and abutted against said base panel, said outer housing comprising an opening in air communication between said exhaust passage and the atmosphere. 
     
     
         3 . The aromatic nebulizing diffuser as claimed in  claim 1 , wherein said holder further comprises an exhaust fitting capped on a top end of said air passage, said exhaust fitting comprising an adjustable exhaust port for adjusting air output direction. 
     
     
         4 . The aromatic nebulizing diffuser as claimed in  claim 1 , wherein said container base of said fluid container comprises an upper part and a lower part, an upwardly extending connection tube defined in said upper part, and a filling port defined in said lower part for the filling of water or an aromatic fluid. 
     
     
         5 . The aromatic nebulizing diffuser as claimed in  claim 2 , wherein said outer housing, said holder and said fluid container are selected from a material group of transparent and translucent materials that admit light. 
     
     
         6 . The aromatic nebulizing diffuser as claimed in  claim 5 , wherein said ultrasonic oscillator comprises at least one light emitting device arranged on a top side thereof. 
     
     
         7 . The aromatic nebulizing diffuser as claimed in  claim 1 , wherein said fluid intake control device comprises a first casing, a second casing, a spring member and a ball, said first casing being connected to the filling port of said container base of said fluid container, said second casing being fastened to a bottom side of said first casing, said first casing having an inside annular flange, said second casing having a ball hole disposed in communication with said oscillation chamber, said spring member being mounted in said first casing and said second casing and stopped at a bottom side of said inside annular flange to hold down said ball on said ball hole. 
     
     
         8 . The aromatic nebulizing diffuser as claimed in  claim 7 , wherein said holder further comprises a protruding portion upwardly extended from said transverse partition board and suspending in said oscillation chamber for insertion into said ball hole of said second casing of said fluid intake control device to move said ball upwardly away from said ball hole against said spring member and to further open the passage between said fluid storage chamber and said oscillation chamber. 
     
     
         9 . The aromatic nebulizing diffuser as claimed in  claim 1 , wherein said oscillation chamber has a volume smaller than said fluid storage chamber. 
     
     
         10 . The aromatic nebulizing diffuser as claimed in  claim 1 , further comprising a gasket ring securing said dip tube to said container base of said fluid container, and a water seal ring packed in between the periphery of said ultrasonic oscillator and the periphery of the center opening of said transverse partition board of said holder. 
     
     
         11 . The aromatic nebulizing diffuser as claimed in  claim 1 , wherein said fluid container further comprises a vent cap capped on a top exhaust hole of said exhaust passage, said vent cap comprising a plurality of vent holes. 
     
     
         12 . The aromatic nebulizing diffuser as claimed in  claim 11 , wherein each said vent hole has a diameter smaller than the diameter of said exhaust passage. 
     
     
         13 . The aromatic nebulizing diffuser as claimed in  claim 1 , further comprising a wireless receiver mounted in said base panel and electrically connected to said power switch and controllable by an external wireless control signal to switch on/off said power switch.
