Description

[0001]This invention is a continuation-in-part of U.S. patent application Ser. No. 12 / 510,400, filed on Jul. 28, 2009.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an aromatic nebulizing diffuser and more particularly, to such an aromatic nebulizing diffuser, which employs oscillation techniques to distribute an aromatic fluid into the air.[0004]2. Description of the Related Art[0005]A known aromatic nebulizing diffuser or essential oil diffuser uses an ultrasonic oscillator to generate a high ultrasonic energy for causing atomization of an essential oil for application. Separation of electric charges in falling rain, caused by breaking up of the water droplets, the drops becoming positively charged and the air negatively charged. This separation of electric charges accompanying the aerodynamic breakup of water drops is known as spray electrification, the waterfall effect or Lenard effect.[0006]However, conventional aromatic nebuliz...

Benefits of technology

[0009]It is still another object of the present invention to provide an aromatic nebulizing diffuser, which produces lighting effects while generating a fine mist of aromatic fluid droplets.

[0010]It is still another object of the present invention to provide an aromatic nebulizing diffuser, which is practical for use to generate a fine mist of aromatic fluid droplets efficiently.

[0011]To achieve these and other objects of the present invention, an aromatic nebulizing diffuser comprises a base; a power switch mounted on the base panel; an electric fan mounted on the base panel and electrically connected to and controllable by the power switch; a holder comprising a transverse partition board, the transverse partition board dividing the holder into an upper part and a lower part, a center opening cut through the transverse partition board, the upper part defining therein an oscillation chamber, the lower part defining a cover, and an air passage set in air communication between the space inside the cover and the oscillation chamber to provide a path for delivering air currents caused by the electric fan; a fluid container mounted in the holder, comprising a container body, a container base fastened to a bottom side of the container body and defining with the container body a fluid storage chamber and an exhaust passage in air communication between the oscillation chamber and the atmosphere for exhaust of a mist of aromatic fluid droplets out of the oscillation chamber; an ultrasonic oscillator mounted in the opening of the holder and electrically connected to the power switch; a fluid intake control device mounted in a bottom side of the fluid container and selectively set between an open status and a close status to control delivery of a fluid from the fluid storage chamber to the oscillation chamber; a dip tube set in the fluid container and the oscillation chamber to communicate the fluid storage chamber and the oscillation chamber; and an outer housing surrounding the fluid container and abutted against the base panel, the outer housing comprising an opening in air communication between the exhaust passage and the atmosphere. This design enables the storage aromatic fluid to be continuously supplied from the fluid storage chamber to the oscillation chamber. Therefore, the invention eliminates the drawback of the prior art design that cannot refill an aromatic fluid automatically.

[0015]Thus, when a fine mist of aromatic fluid droplets is forced out of the exhaust passage of the fluid container and the outer housing into the atmosphere during operation of the electric fan, the fine mist of aromatic fluid is lightened by the light emitted by the light-emitting device, showing colorful lighting effects.

Problems solved by technology

However, conventional aromatic nebulizing diffusers can simply produce an upwardly flying mist of aromatic gas.

They cannot simulate the natural visual effect of a flying mist caused by the impact of a waterfall.

Thus, regular aromatic nebulizing diffusers are less effective.
