Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an aromatic nebulizing diffuser and more particularly, to a combination aromatic nebulizing diffuser and color light set assembly that provides a colorful lighting effect when causing atomization of an aromatic fluid. 
     2. Description of the Related Art 
     Commercial aromatic nebulizing diffusers commonly use oscillator means to generate a high ultrasonic energy for causing atomization of an essential oil. These aromatic nebulizing diffusers do not produce any visual lighting effects. There are aromatic nebulizing diffusers with a lamp arranged therein. However, because the housing or outer shell does not admit light, people cannot see the floating of the generated fine mid in the housing or outer shell. 
     Further, a conventional aromatic nebulizing diffuser with a lamp simply uses a light emitting device to emit light. The lighting of the light emitting device is monotonous, insufficient to attract people&#39;s eyes. 
     Further, regular aromatic nebulizing diffusers commonly use screws to affix component parts together, complicating mounting and dismounting procedures. After a long use, the inside wall of the aromatic nebulizing diffuser may be covered with a layer of dirt. It takes much time and labor to practice a cleaning work. 
     Further, regular aromatic nebulizing diffusers commonly have a narrow flow passage for guiding out the generated fine mist of atomized aromatic fluid molecules. Thus, the amount of the generated fine mist of atomized aromatic fluid molecules being carried out of the housing or outer shell is limited. 
     Further, during operation of the oscillator to cause atomization of the aromatic fluid, the aromatic fluid may be causes to fly out of the housing or outer shell, causing contamination.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to  FIGS. 1˜4 , a combination aromatic nebulizing diffuser and color light set assembly  100  in accordance with the present invention is shown comprising a base panel  10 , a power adapter  21 , two electric fans  30 , a shell  40 , a fluid container  50 , a color light set  60 , an oscillator  70 , a plurality of light guide tubes  80  and a cover  90 . 
     Referring to  FIGS. 2˜4  again, the base panel  10  defines two fan mounting zones and a power adapter mounting zone. Further, the base panel  10  comprises a plurality of air vents  11  cut through the top and bottom wall in each of the two fan mounting zones, and a plurality of upright support tubes  12  perpendicularly upwardly extended from the top wall. 
     Referring to  FIGS. 2˜4  again, the power adapter  21  is mounted in the base panel  10  within the power adapter mounting zone for the connection of an external power cable (not shown) for the input of an external power source. 
     Referring to  FIGS. 2˜4  again, the two electric fans  30  are respectively mounted on the top wall of the base panel  10  in each of the two fan mounting zones and electrically connected with the power adapter  21  to obtain the necessary working voltage from the power adapter  21 . When the electric fans  30  are started, outside fresh air is drawn through the air vents  11  into the inside of the combination aromatic nebulizing diffuser and color light set assembly  100 . 
     Referring to  FIGS. 1˜4 , the shell  40  is shaped like a hollow rectangular box, having four legs  41  respectively downwardly extended from the bottom side in four corners for positioning on a flat surface stably. 
     Referring to  FIGS. 2 and 3 , the fluid container  50  comprises a bottom wall  51 , an upright peripheral wall  52  upwardly extended from the border of the bottom wall  51 , a fluid chamber  54  surrounded by the bottom wall  51  and the upright peripheral wall  52  and two air conduits  53  suspending in the fluid chamber  54 , a center opening  511  cut through the bottom wall  51  in communication between the fluid chamber  54  and the outside space, and a plurality of through holes  513  cut through the bottom wall  51  around the center opening  511 . Each air conduit  53  has an air inlet  531  and an air outlet  532 . The air outlet  532  is kept in air communication with the inside space of the fluid chamber  54 . The air inlet  531  faces one electric fan  30 . Further, the bottom wall  51  of the fluid container  50  is supported on the top wall of the shell  40 . The base panel  10  is fastened to the bottom wall of the shell  40 . The fluid container  50 , the base panel  10  and the shell  40  are fixedly fastened together, keeping the air inlets  531  of the air conduits  53  in alignment with the electric fans  30  respectively. 
     Referring to  FIGS. 2˜4 , the color light set  60  comprises a circuit board  61  and a plurality of color light emitting devices  62  installed in the circuit board  61 . The circuit board  61  is fixedly attached to the bottom (outer) surface of the bottom wall  51  of the fluid container  50  and electrically connected to the power adapter  21 . The color light emitting devices  62  are respectively inserted through the through holes  513  into the inside of the fluid chamber  54 . 
     Referring to  FIGS. 2˜4 , the oscillator  70  according to the present preferred embodiment is an ultrasonic oscillator mounted in the center opening  511  at the center of the bottom wall  51  of the fluid container  50  and electrically connected to the power adapter  21  to obtain the necessary working voltage from the power adapter  21 . 
     Referring to  FIGS. 2˜4 , the light guide tubes  80  are vertically positioned in the fluid chamber  54  of the fluid container  50  with one ends thereof respectively surrounding the color light emitting devices  62  in the through holes  513 . 
     Referring to  FIGS. 1˜4 , the cover  90  is covered on the fluid container  50 , having a plurality of through holes  91  cut through the top and bottom walls thereof at locations corresponding to the light guide tubes  80  and kept in proximity to the topmost edge of each of the light guide tubes  80  for output of the generated fine mist of atomized aromatic fluid molecules. The cover  90  further comprises an annular flange  92  downwardly protruded from the bottom wall thereof at the center corresponding to the center opening  511  of the fluid container  50  for stopping the generated fine mist of atomized aromatic fluid molecules from diffusion in horizontal direction and prohibiting splashing of the aromatic fluid during atomization. 
     After understanding of the structural features of the component parts of the combination aromatic nebulizing diffuser and color light set assembly  100  and their mounting arrangement, the application of the combination aromatic nebulizing diffuser and color light set assembly  100  is described hereinafter. 
     When in use, pour an aromatic fluid (for example, the mixture of an essential oil and water) into the fluid chamber  54  of the fluid container  50 , and then start the oscillator  70  to generate an ultrasonic energy for causing atomization of aromatic fluid. At this time, the electric fans  30  are started to draw in outside fresh air. The intake flow of air goes through the air inlets  531  and air outlets  532  of the air conduits  53  into the inside space of the fluid chamber  54  to carry the generated fine mist of atomized aromatic fluid molecules through the through holes  91  of the cover  90  to the outside space. At the same time, the light guide tubes  80  condense the color light from the color light emitting devices  62  into color light beams, producing a visual effect. 
     Referring to  FIGS. 4 and 5 , each air conduit  53  has an inner diameter gradually reducing in direction from the air inlet  531  toward the air outlet  532 . When the induced current of air goes through one air conduit  53 , the speed of the induced current of air is accelerated. Therefore, the air currents that go out of the air conduits  53  carry the generated fine mist of atomized aromatic fluid molecules through the through holes  91  of the cover  90  to the outside space efficiently. 
     During oscillation of the oscillator  70  in the aromatic fluid in the fluid chamber  54  of the fluid container  50 , the annular flange  92  prohibits horizontal diffusion of the generated fine mist of atomized aromatic fluid molecules, enabling the generated fine mist of atomized aromatic fluid molecules to be carried by the induced currents of air from the fluid chamber  54  through the through holes  91  of the cover  90  to the outside space efficiently. 
     Further, each color light emitting device  62  of the color light set  60  can be comprised of a red light emitting diode chip, a blue light emitting diode chip, a green light emitting diode chip, or the combination of a red light emitting diode chip, a blue light emitting diode chip and a green light emitting diode chip. Subject to the control of the circuit board  61 , the color light emitting devices  62  emit mixed colors of light. The light guide tubes  80  condense the mixed colors of light into color light beams that go through the through holes  91  of the cover  90  to the outside space to illuminate the fine mist of atomized aromatic fluid molecules being carried out of the combination aromatic nebulizing diffuser and color light set assembly  100  by the induced currents of air. 
     Further, the circuit board  71  of the color light set  60  has an opening  611  for accommodating the oscillator  70 . 
     Referring to  FIGS. 1 and 2 , the shell  40  has a power adapter hole  42  located on one lateral side thereof for receiving a part of power adapter  21  so that an external power cable (not shown) can be conveniently connected to the power adapter  21 . 
     Referring to  FIG. 5 , the fluid container  50  and the cover  90  can be prepared from a transparent material, translucent material, or any of a variety of other materials that admit light, such as glass, ceramics, frosted glass, acrylic, plastics or crystal. Further, the fluid container  50  and the cover  90  can be made in any desired color. Thus, people can see through the combination aromatic nebulizing diffuser and color light set assembly  100 , viewing the floating of the generated fine mist of atomized aromatic fluid molecules and the presence of the mixed color of lights in the fluid container  50 . 
     Further, the aforesaid light guide tubes  80  can be prepared from glass, frosted glass, acrylic, plastics or crystal in any desired color for guiding the colors of light emitted from the light emitting devices  62  out of the fluid container  50  and the cover  90  in beams. 
     Further, the aforesaid light guide tubes  80  are preferably tapered, having a diameter gradually reducing in direction from the through holes  513  of the fluid container  50  toward the through holes  91  of the cover  90 . Therefore, the light guide tubes  80  effectively condense the colors of light emitted from the light emitting devices  62  into upwardly extending color light beams, producing visual lighting effects. 
     Referring to  FIGS. 2˜4 , the oscillator  70  comprises a built-in control circuit that controls the oscillator  70  to oscillate in frequency about several million cycles per second. Further, the oscillator  70  is mounted in the center opening  511  on the bottom wall  51  of the fluid container  50  and sealed with a gasket ring  98  to prevent leakage. 
     Referring to  FIGS. 2˜4 , the oscillator  70  carries a water lever sensor  71  and a light source  72 . The water level sensor  71  is disposed in the fluid chamber  54  of the fluid container  50  and adapted to detect the level of the contained aromatic fluid. The light source  72  is controllable to emit light, thereby illuminating the fluid chamber  54 . The built-in control circuit of the ultrasonic oscillator  70  controls the operation of the water lever sensor  71  and a light source  72 . When the level of the aromatic fluid in the fluid chamber  54  is below a predetermined value, the control circuit of the ultrasonic oscillator  70  cuts off power supply from the ultrasonic oscillator  70 , preventing damage. Further, the light source  72  can be comprised of at least one LED component adapted for emitting a predetermined color of light. 
     The aforesaid fluid container  50  further comprises a plurality of bottom mounting rods  512  downwardly extended from the bottom wall  51 ; the base panel  10  comprises a plurality of upright mounting tubes  12  for receiving the bottom mounting rods  512  of the fluid container  50 . Thus, the base panel  10  can be detachably fastened to the fluid container  50 , facilitating cleaning. 
     Further, after plugging the bottom mounting rods  512  of the fluid container  50  into the upright mounting tubes  12  of the base panel  10 , screws (not shown) may be installed to affix the base panel  10  to the fluid container  50 . 
     The combination aromatic nebulizing diffuser and color light set assembly  100  further comprises an audio source input connector  22  mounted on the base panel  10  for the connection of an external sound source, for example, a music player or multimedia storage device (not shown) for sound source input. 
     The combination aromatic nebulizing diffuser and color light set assembly  100  further comprises a music control circuit board  23  mounted on the base panel  10  and electrically connected to the power adapter  21 , having storage means for storing natural voices, music files, animal sounds or the like. 
     The combination aromatic nebulizing diffuser and color light set assembly  100  further comprises a speaker  24  mounted on the base panel  10  above sound holes  13  on the base panel  10  and electrically connected to the audio source input connector  22  and the music control circuit board  23  to convert an electrical signal from the audio source input connector  22  or the music control circuit board  23  into sound that is driven out of the combination aromatic nebulizing diffuser and color light set assembly  100  through the sound holes  13  of the base panel  10 . Therefore, sound and lighting effects are created during operation of the combination aromatic nebulizing diffuser and color light set assembly  100 . Further, the shell  40  shields the speaker  24 , the electric fans  30  and the music control circuit board  23 , enabling the audio source input connector  22  to be partially mounted in an audio source connector mounting through hole  43  on the shell  40  for the connection of external sound source means. 
     A prototype of combination aromatic nebulizing diffuser and color light set assembly has been constructed with the features of  FIGS. 1˜5 . The combination aromatic nebulizing diffuser and color light set assembly functions smoothly to provide all of the features disclosed earlier. 
     Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
