Abstract:
The present invention pertains to a method for mixing forced airflow with aromatic gas and its relevant mixing apparatus. The method mainly mixes the forced airflow with an aromatic gas or other proper gases in time of traveling. That is, passing a certain amount of forced airflow through a flowing route and guiding an aromatic gas to travel along the route so as to ensure the forced airflow can exactly absorb the aromatic gas and obtain the steady consistency after the mixing procedure.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a method for mixing gases and the relevant apparatus, more particularly to a method for equably mixing forced airflow or vapor with aromatic gas and its relevant apparatus. 
         [0003]    2. Description of the Related Art 
         [0004]    Generally, the apparatus utilized by incorporating the atomized vapor or gases into some other aromatic gases is usually applied to create a pleasant atmosphere, release the pressure, or cure some other respiratory diseases. One traditional method for the combination is to directly feeding the aromatics into the forced airflow. Another method is to have a container filled with water and pour some aromatics into water(e.g. aroma oil or other appropriative powders); thence to process the admixture of water and aromatics by heating or by supersonic oscillating methods thereby generating water vapor or atomized vapor which has sweet smells; said water vapor or atomized vapor contains the aromatic gases exhaled through the aromatics, and reaches the purposes of producing atmosphere. 
         [0005]    By means of the above typical method, the finished water vapor facilely contains an unsteady proportion of the aromatic component with high consistency while directly mixing the water molecule with those aromatics and proceeding it into a vapor state, which may result of the symptom of hypersensitiveness among users who are unable to adjust themselves to those smells. Further, the consistency would be on the decline according to the consuming time and formed of an inconsistent diffusion of the aromatic smelling, thus still requires improvement. 
       SUMMARY OF THE INVENTION 
       [0006]    Therefore, the object of the present invention is to provide a method for adequately mixing forced airflow with aromatic gas so as to improve the unsteady consistency after the combination. 
         [0007]    Another object is to provide an apparatus applied to proceed the mixing procedure which facilitates to generate the aromatic smell via a simple operation. 
         [0008]    The method for mixing forced airflow with aromatic gas in conformity with the present invention essentially provides the steps of passing a certain amount of forced airflow through a flowing route and guiding an aromatic gas to travel along the route so as to steadily mix the two materials and generate the admixed gases with sweet smell. 
         [0009]    The apparatus with respect to the method of the present invention has a mixing device which is comprised of an upper case, a lower case, and an accommodating room for mounting a gas mixing assembly therein; wherein, the gas mixing assembly mainly includes respective a first opening and a second opening disposed on both sides thereof and defines a flowing route existed inside the room thereby permitting the forced airflow to be smoothly introduced therein and adequately mix with an aromatic gas to produce aromatic smell with steady consistency. 
         [0010]    The advantages of the present invention over the known prior arts will become more apparent to those of ordinary skilled in the art by reading the following descriptions with the relating drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0016]    Referring to  FIG. 1 ,  3  and  4 , the preferred embodiments of the present invention essentially has a mixing device  10 , which comprises an upper case  12 , a lower case  11 , and an accommodating room  13  defined therebetween for disposing a gas mixing assembly  20  therein and forming a gas mixing chamber  27 ; wherein, the mixing device  10  has a first opening  111  and a second opening  121  respectively disposed on both sides thereof so as to form a flowing route functioning as introducing a certain of forced airflow into the accommodating room  13 . Further, a gas mixing assembly  20  is mounted inside the device  10  for mixing the forced airflow with an aromatic gas thereby and assists in diffusing the admixed gas out of the device  10 . The forced airflow herein can be adopted by a high pressure gas or an atomized vapor. 
         [0017]    Still further, the first opening  111  is formed at the bottom side of the lower case  11 , and a first anti-counterflow member  112  is disposed on the first opening  111 , and then an extending portion  113  is downwardly extended therefrom for connecting to an external duct  40 . Additionally, the lower case  11  has a room opening on its top end and makes the accommodating room  13  to be formed of a long-tubular contour. The upper case  12  covers the room opening of the lower case  11  and accommodating room  13  communicates with the lower case  11  via the second opening  121  disposed at bottom side of the upper case  12 , and two coverings  14  separately disposed on the upper case  12  and the lower case  11  for blocking the two openings  111  and  121 . 
         [0018]    In addition, the gas mixing assembly  20  comprises a containing assembly  21 , a first shield plate  22 , a second shield plate  23 , a filter piece  24 , and a guiding unit  25 ; Still referring to  FIG. 2  and  FIG. 3 , the containing assembly  21  formed of a bowl contour includes a loading case  211  for accurately fitting with the first opening  111 , at least one aroma generator  30  mounted in the loading case  211 , and a conducting tube  212  axially disposed therethrough so that the conducting tube  212  has a bottom end thereof to be in contact with the first opening  111 . Moreover, the aroma generators  30  can contain aroma oil, appropriate powders, or other proper materials. The conducting tube  212  has a filtering unit  26  (e.g. sponge) arranged therein and has an orifice defined at its top end and attached to a first shield plate  22  for communicating with the gas mixing chamber  27 . The first shield plate  22  provides with a clapboard  221  with an outer edge thereof abutting on an inner wall of the accommodating room  13 , a third opening  222  disposed on the clapboard  221 , a connecting portion  223  downwardly extended from the circumference of the third opening  222  for making the conducting  212  communicated with the third opening  222 , a plurality of apertures  224  disposed on the surface of the clapboard  221 , a fence structure  225  upwardly extends from the third opening  222 , and supporting pieces  226  disposed on the clapboard  221  for engaging with a second shield plate  23 ; wherein, the accommodating room  13  is divided into upper and lower chambers and the two chambers communicate with each other via the clapboard  221 ; further the upper chamber, namely the gas mixing chamber  27 , is applied for mixing the forced airflow and the aromatic gas. Additionally, the fence structure  225  comprises a shield piece  2251  parallel to the third opening  222  in cross section and a plurality of upper and lower posts  2252 ,  2253  vertically disposed on an outer circumference of the shield piece  2251 ; wherein, the lower posts  2253  extend from an underside of the shield piece  2251  and passes through the third opening  222 , and the upper posts  2252  extend from an upper side of the shield piece  2251 . 
         [0019]    The second shield plate  23  is formed of a quasi-funnel configuration and has a fourth opening  231  defined at its bottom side which is connected to the upper posts  2252  of the fence structure  225 , a shield opening at its top side, and a shoulder portion  232  formed on a periphery of the shield opening; wherein, a second anti-counterflow member  233  is disposed on the fourth opening  231 , and the shoulder portion  232  covers part of the room opening of the lower case  11 . Furthermore, the filter piece  24  is disposed between the second shield plate  23  and the guiding unit  25 . The guiding unit  25  further includes a guiding base  252  attached to the shoulder portion  232  of the second shield plate  23 , and a guiding mouth  251  protruded from the base  252  and going through the second opening  121  to communicate with outsides and connect to the external  40 . (refer to  FIG. 4 ). 
         [0020]    In one operation, the external duct  40  is initially connected to the mixing device  10  as arrowed in  FIG. 4 and 5  for feeding forced airflow along a gas feeding entrance of the flowing route into the device  10 , to be more precisely illustrated in  FIG. 4 , the forced airflow is constrainedly introduced from the external  40  to the accommodating room  13  of the mixing device  10 , and then into the first opening  111  of the lower case  11 , travels through the conducting tube  212  of the containing assembly  21 , and thence passes the third opening  222  to enter into the upper chamber of the clapboard  221  by the assistance of the shield piece  2251 . Simultaneously, in the lower chamber which is located beneath the clapboard  221 , the aroma generators  30  disposed on the containing assembly  21  emit the aromatic gas into the loading case  211 , and subsequently the aromatic gas goes across the apertures  224  and diffuses throughout the gas mixing chamber  27  (the upper chamber), so that the forced airflow can completely absorb the aromatic gas therein. Of further operation, the forced airflow can also be directly diffused from the top end of the conducting tube  212  to the upper chamber without passing through the first shield plate  22  for proceeding further combination. Then an admixed gas generated by the combination would go into the gas mixing chamber  27  through the apertures  224 . 
         [0021]    Still referring to  FIG. 4 , while the forced airflow and the aromatic gas stay within the gas mixing chamber  27  and mix with each other to form an admixed gas, the new forced airflow incessantly goes into the chamber  27  and expels the admixed gas therefrom. The admixed gas further moves toward the second shield plate  23 , that is, the admixed gas passes across the shield piece  2251  disposed on the fence structure  225 , goes into the second shield plate  23  via the passing the fourth opening  231 , thence enters in sequence to the filter piece  24  and the guiding unit  25 , and finally exits from the guiding mouth  251 . The gas can also be discharged from another external duct  40  which is connected to the upper case  12  (shown in  FIG. 5 ). Additionally, the new forced airflow inside the mixing device  10  still keeps absorbing the aromatic gas which has been diffused throughout the chambers, thus obtain the admixed gas with steady proportion of the consistency. 
         [0022]    To sum up, the present invention takes advantages of the method for mixing forced airflow with the aromatic gas emitted from the aromatics or powders, so that the forced airflow can absorb the aromatic gas instead of mixing with the substantial materials. Deservedly, users can also arrange suitable introducing devices for introducing other forced airflow (e.g. atomized vapor or other smell gases) into the mixing device  10  through the front side of its gas feeding entrance or the rear side of its gas feeding exit, thereby generating multiple admixed gases. Thus, the present invention facilitates to provide an efficient and facile operation and maintain the steady proportion of the consistency after the combination. 
         [0023]    While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
