Abstract:
An aroma mist spraying device includes a container, an air pipe, an air supply motor, and an aroma supply pipe. A high speed air flow produced by the air supply motor may be injected from the air pipe toward the aroma supply pipe, thereby sucking the aroma into the container, and thereby forming a misting effect.

Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to an aroma mist spraying device, and more particularly to an aroma mist spraying device, wherein the high speed air flow produced by the air supply motor may be injected from the air pipe toward the aroma supply pipe, thereby sucking the aroma into the container, and thereby forming a misting effect.  
           [0003]    2. Description of the Related Art  
           [0004]    A conventional aroma seat is provided with a candle or an alcohol lamp that may be burned to heat the aroma contained in the aroma seat, thereby spreading the fragrance of the aroma. However, if the candle or the alcohol lamp is upset, it easily burns other article, thereby causing danger. In addition, the aroma is easily volatilized during the heating process, so that it is necessary to add and replenish the aroma frequently, thereby causing inconvenience to the user.  
         SUMMARY OF THE INVENTION  
         [0005]    The primary objective of the present invention is to provide an aroma mist spraying device, wherein the high speed air flow produced by the air supply motor may be injected from the air pipe toward the aroma supply pipe, thereby sucking the aroma into the container, and thereby forming a misting effect.  
           [0006]    In accordance with the present invention, there is provided an aroma mist spraying device, comprising:  
           [0007]    a container;  
           [0008]    an air pipe connected to the container;  
           [0009]    an air supply motor for supplying air through the air pipe into the container; and  
           [0010]    an aroma supply pipe connected to the container for supplying an aroma into the container; wherein:  
           [0011]    the aroma is pushed upward through the aroma supply pipe into the container according to a syphon principle; and  
           [0012]    the aroma supplied from the aroma supply pipe into the container is misted by an accelerated air flow from the air pipe according to a Bernoulli&#39;s principle.  
           [0013]    Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0019]    Referring to the drawings and initially to FIGS. 1 and 2, an aroma mist spraying device  10  in accordance with a first embodiment of the present invention comprises an air supply motor  20 , a container  30 , an air pipe  40 , and an aroma supply pipe  50 .  
         [0020]    The air supply motor  20  is a rectangular structure, and is provided with a plug  21 , a circular hollow air drain portion  22 , and a circular hollow soft conduit  23 . The plug  21  of the air supply motor  20  may be connected to a common household electric power. The gas generated in the air supply motor  20  may be drained outward from the air drain portion  22  of the air supply motor  20 . The conduit  23  of the air supply motor  20  has a first end connected to the air drain portion  22  of the air supply motor  20 , and a second end connected to the air pipe  40  that is connected to the container  30 .  
         [0021]    The container  30  is a transparent thin structure, and has an upper portion provided with a corrugated mouth  31 , and has a lower portion provided with an aroma receiving portion  32 . The container  30  has a mediate portion provided with a stop portion  60  for stopping a part of aroma, so that the aroma may be recycled and reused.  
         [0022]    The air pipe  40  is mounted in the container  30 , and has a first end extended outward from the container  30  and provided with an air inlet portion  41  that is connected to the conduit  23  of the air supply motor  20 . The air pipe  40  has a second end received in the container  30  and provided with a tapered air outlet hole  42  that has a reduced diameter.  
         [0023]    The aroma supply pipe  50  is mounted in the container  30 , and has a first end extended outward from the container  30  and provided with an aroma inlet hole  51  for supplying the aroma into the aroma supply pipe  50 . The aroma supply pipe  50  has a second end received in the container  30  and provided with a tapered aroma outlet hole  52  that has a reduced diameter. An included angle is defined between the aroma outlet hole  52  of the aroma supply pipe  50  and the air outlet hole  42  of the air pipe  40 . Preferably, the aroma supply pipe  50  and the air pipe  40  are integrally formed with each other.  
         [0024]    In operation, the high speed gas generated in the air supply motor  20  may be drained outward from the air drain portion  22  of the air supply motor  20  into the conduit  23  of the air supply motor  20 , may then be conveyed through the air inlet portion  41  into the air pipe  40 , and may then be injected outward from the air outlet hole  42  of the air pipe  40 .  
         [0025]    According to the Bernoulli&#39;s principle, when the gas injected outward from the air outlet hole  42  of the air pipe  40 , the diameter of the air outlet hole  42  of the air pipe  40  is reduced, so that the flow speed at the air outlet hole  42  of the air pipe  40  is increased. Thus, the injected gas is accelerated, and is blown toward the aroma outlet hole  52  of the aroma supply pipe  50 , so that the aroma outlet hole  52  of the aroma supply pipe  50  may produce a vacuum state. Thus, according to the syphon principle, the aroma contained in the aroma supply pipe  50  is pushed upward by the difference of pressure, so that the aroma may be pushed outward from the aroma outlet hole  52  of the aroma supply pipe  50 . At the same time, the high speed air flow is blown from the air outlet hole  42  of the air pipe  40  toward the aroma outlet hole  52  of the aroma supply pipe  50 , so that the aroma from the aroma outlet hole  52  of the aroma supply pipe  50  may produce a misting effect. The stop portion  60  of the container  30  may be used for stopping a part of the aroma, so that the aroma may be recycled and reused.  
         [0026]    Referring to FIG. 3, in accordance with a second embodiment of the present invention, the aroma outlet hole  52  of the aroma supply pipe  50  is vertical to the air outlet hole  42  of the air pipe  40 .  
         [0027]    Referring to FIG. 4, in accordance with a third embodiment of the present invention, the air inlet portion  41  of the air pipe  40  is located at the lowermost position of the container  30 .  
         [0028]    Referring to FIG. 5, in accordance with a fourth embodiment of the present invention, the aroma mist spraying device  10  further comprises a seat  70  has a central portion provided with a recessed positioning portion  71  for positioning the container  30 , and provided with multiple lamps  72  arranged around the positioning portion  71 . The seat  70  has a bottom provided with an electric cord  83  that may be connected to the electric power so that the aroma mist spraying device  10  may function as a night lamp that may spread the aroma.  
         [0029]    Accordingly, the aroma mist spraying device  10  in accordance with the present invention has the following advantages.  
         [0030]    1. The aroma mist spraying device  10  needs not to be heated or ignited, so that the aroma mist spraying device  10  may be used safely.  
         [0031]    2. The plug  21  of the air supply motor  20  may be connected to a common household electric power, so that the aroma mist spraying device  10  may be used conveniently.  
         [0032]    3. The stop portion  60  of the container  30  may be used for stopping a part of the aroma, so that the aroma may be recycled and reused.  
         [0033]    While the preferred embodiment of the present invention has been shown and described, it will be apparent to those skilled in the art that various modifications may be made in the embodiment without departing from the spirit of the present invention. Such modifications are all within the scope of the present invention.
