Description:
FIELD OF THE INVENTION  
      A nebulizing apparatus for medical use with improved nozzle positioning structure, and more particularly to a nebulizing apparatus for medical use with improved nozzle positioning structure having a nozzle and a nebulizing device connected to each other by means of engagement protrusions and engagement grooves.  
     BACKGROUND OF THE INVENTION  
      In the prior arts, Taiwan Patent No. 567855 and U.S. Publication No. 2001/0002592 A1 disclosed an apparatus for nebulizing a liquid for medical use nebulizes a liquid medicine to fully generate the cure effect and includes a main body provided with an air compressor disposed therein, a nebulizing device to receive liquid medicine connected to the air compressor the liquid medicine, and an output device. The air compressor compresses the air in high speed and delivers the compressed air to the nebulizing device. The nebulizing device nebulizes the liquid medicine, and the output device outputs the nebulized liquid medicine for medical use.  
      In above-mentioned prior arts, the output device is disposed on the cover of the nebulizing device. The output device includes an input portion with smooth annular edge, and the cover of nebulizing device has a smooth annular groove for housing and centering the input portion of the output device. Therefore, when the output device is attached to the nebulizing device, it can rotate smoothly in the annular groove to change the direction of the output portion.  
      Nevertheless, since the output device can rotate smoothly on the nebulizing device, user often experiencing inconveniences when trying to fix the direction of the output device, which easily swiveling around the annular groove whenever it is touched incautiously.  
     SUMMARY OF THE INVENTION  
      The objective of the present invention is to provide a nebulizing apparatus for medical use with improved nozzle positioning structure capable of adjusting and fixing the direction of the nozzle according to a user.  
      In order to achieve the foregoing objective, the present invention provides a nebulizing apparatus for medical use with improved nozzle positioning structure including a nozzle and a nebulizing device connected to each other by means engagement protrusions and engagement grooves. A cover of the nebulizing device is provided with a plurality of engagement grooves and lumpy portions disposed around the inner wall and outer wall of the cover. An input portion of the nozzle has an engagement protrusion which can be assembled corresponding to the inner wall engagement grooves of the cover to fix the position the nozzle. The nozzle can then be pulled out, rotates to suitable angle and then installed to the cover of the nebulizing device if a different direction of the nozzle is desired.  
      It is another objective of the present invention that the nozzle can be stored inside the protective cover to maintain the sanitary condition of the nozzle after usage of the nebulizing apparatus.  
      In order to achieve the foregoing objectives, the present invention discloses a protective cover having two fixing portions which are disposed on an inner wall of the protective cover and in accordance with the input portion of the nozzle, such that the input portion of the nozzle is embedded between the two fixing portions during installation and cannot be dropped. Then, the protective cover is disposed on the main body for further receiving the nozzle so as to save space and keep the nozzle clean.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      Referring to  FIG. 1 , it depicts a perspective schematic view of a nebulizing apparatus for medical use with improved nozzle positioning structure of the present invention. As shown in  FIG. 1 , the apparatus includes a main body  1  provided with an air compressor  2  disposed therein (shown in  FIG. 2 ), a nebulizing device  3  to receive liquid medicine installed on the air compressor  2 , a nozzle  4  installed on the nebulizing device  3 , a bottom base  5  installed on a bottom of the main body  1 , and a protective cover  6  installed on the main body  1  and receiving the nozzle  4 . The air compressor  2  of the present invention compresses the air in high speed and transport the compressed air to the nebulizing device  3 . The nebulizing device  3  nebulizes the liquid medicine, and the nozzle  4  outputs the nebulized liquid medicine for medical use.  
      Referring to  FIG. 2 , it depicts a perspective exploded schematic view of a nebulizing apparatus for medical use with improved nozzle positioning structure of the present invention. As shown in  FIG. 2 , the main body  1  has an open receiving space  11  for assemblage with the air compressor  2  and exposing the air compressor  2  for assemblage with the nebulizing device  3 , wherein an inner wall of the receiving space  11  has at least one first engagement protrusion  111 .  
      The nebulizing device  3  has a medicine cup  31  and a cover  32  disposed on the medicine cup  31 , wherein the cover  32  is provided with a plurality of engagement grooves  321  disposed around an inner wall of the cover  32  and a plurality of lumpy portions  322  disposed around an outer wall of the cover  32 , whereby the first engagement protrusion  111  of the receiving space  11  can be meshed into the lumpy portions  322  accordingly when the nebulizing device  3  is installed on the air compressor  2 .  
      The nozzle  4  has an input portion  41  and an output portion  42 , wherein the input portion  41  of the nozzle  4  has at least one second engagement protrusion  43  which can be meshed into the engagement grooves  321  accordingly during installation.  
      The protective cover  6  has two fixing portions  61  which are disposed on an inner wall of the protective cover  6  and corresponding with the input portion  41  of the nozzle  4 , such that the input portion  41  is embedded between the two fixing portions  61  during installation.  
       FIGS. 3 and 4  depict a top plan schematic view and a perspective schematic view showing an embodiment of the present invention. As shown in  FIGS. 3 and 4 , the nozzle  4  can be positioned by utilizing the engagement between engagement protrusion of the nozzle and engagement grooves of the cover, such that a user won&#39;t change the direction of the output portion  42  of the nozzle  4  during usage due to incautious touch. If the user wants to change the direction of the output portion  42 , the user can pull the nozzle  4  and then install the nozzle  4  to the engagement grooves  321  of the cover  32  with different angle so as to meet the requirement of the user. Furthermore, the engagement between first engagement protrusion of the receiving space  11  and lumpy portions  322  of the cover will prevent undesired rotation of the cover on the medicine cup  31  during usage.  
      Although the invention has been explained in relation to its preferred embodiment, it is not used to limit the invention. It is to be understood that many other possible modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the invention as hereinafter claimed.
