BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates generally to an air brush, and more particularly to an air brush having a paint container with lid.  
         [0003]     2. Description of the Related Art  
         [0004]      FIG. 4  and  FIG. 5  show a conventional air brush including a brush member  8 , a paint container  9 , a gas injection member  93  and a control assembly  94 . The brush member  8  has a chamber  81  therein and defines a head portion  82  and a rear portion  83  at opposite ends thereof. A nozzle  821  is provided at the head portion  82  of the brush member  8 . The paint container  9  has a cup  91  to receive paint therein. The cup  91  has an opening  911  at a top thereof and a bore  912  at a bottom thereof. The bore  912  communicates the cup  91  with the chamber  81  in the brush member  8 . A lid  91  is provided on the cup  91  to seal the opening  911 . The gas injection member  93  is connected to the chamber  81  of the brush member  8  to issue high pressure gas to an air channel  84  in the brush member  8 . The gas injection member  93  has a valve  931  therein to close and open the gas injection member  93 . The valve  94  is received in the brush member  8  with a needle extended to the nozzle  821  to control the paint flow.  
         [0005]     To fill paint in the paint container  9 , the lid  92  has to be taken off, and put on the cup  91  again after the paint had been filled. Some users lose the lid  92  when fills the paint, but the stores do not sell the lid  92  only. The user has to buy a new air brush only because of the miss of the lid.  
       SUMMARY OF THE INVENTION  
       [0006]     The primary objective of the present invention is to provide a paint brush, which the lid is fastened to the brush to prevent it from losing.  
         [0007]     According to the objective of the present invention, an air brush comprises a brush member having a head portion, on which a nozzle is provided, and an air channel communicated with the nozzle. A paint container is provided on the brush member, which has a cup and a lid, wherein the cup has an opening at a top and a bore at a bottom communicated with the brush member. A gas injection member is connected to the brush member and communicated with the air channel to issue a high pressure gas to the nozzle. A valve assembly is received in the gas injection member to control a paint flow in the nozzle. A connector connects the cup and the lid to make the lid always connects the cup even when the lid is opened.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0013]     As shown in FIGS.  1  to  3 , an air brush of the preferred embodiment of the present invention comprises:  
         [0014]     A brush member  1  has a head portion  11  and a rear portion  12  at opposite end thereof. A nozzle  111  is provided at the head portion  11 . The brush member  1  further has a chamber  13  and an air channel  4  therein communicated with the nozzle  111 .  
         [0015]     A paint container  2  has a cup  21  on the brush member  1 , a lid  22  and a connector  3 . The cup  21  has a bore  212  at a bottom to connect to the chamber  13  via a paint tube  214  and an opening  213  at a top thereof where the lid  22  is closed. The connector  3  has a first bonding portion  31  and a second bonding portion  32 , wherein the first bonding portion  31  is connected to an out surface of the cup  21  adjacent to the opening  213 , and the second bonding portion  32  is connected to a top of the lid  22 .  
         [0016]     A gas injection member  41  is connected to the brush member  1  and communicated with the air channel  4  to issue a high pressure gas to the nozzle  111 .  
         [0017]     An adjustment member  5  has a button portion  51 , a post  52  projected from a bottom of the button portion  51  and an aperture  53  on the post  52 . The post  52  is inserted into the chamber  13 , and the button portion  51  is left out of the brush member  1 .  
         [0018]     A control assembly  6  is received in the chamber  13  of the brush member  1 . The control assembly  6  includes a needle  61  with a tip end  611  and a control set  62 . The needle  61  passes through the control set  62  and the adjustment member  5  with the tip end  611  received in the nozzle  111 . The tip end  611  of the needle  61  of the control assembly  6  is moved inwards and outwards the nozzle  111  to control the paint flow.  
         [0019]     A valve assembly  7  is received in the gas injection member  41  including a shaft  71 , a spring  72  and a sleeve  73 . The shaft  71  is connected to the post  52  of the adjustment member  5 . The spring  72  and the sleeve  73  are fitted to shaft  71 . The valve assembly  7  is adapted to open or close the gas injection member  41 .  
         [0020]     In operation, the button portion  51  of the adjustment member  5  is pressed to move the shaft  71  of the valve member  7 , such that the gas is issue to the nozzle  111  via the gas injection member  41  and the air channel  4 . The paint in the cup  21  of the paint container  2  flows to the chamber  13  via the bore  212  and the paint tube  214 , and then flows to the nozzle  111 . Now the adjustment member  5  is moved forward to move the needle  61  to select a suitable gap in the nozzle  111 . A difference in pressure between inside and outside of the nozzle  111  makes the paint spray out.  
         [0021]     The connector  3  connects the lid  21  to the cup  21  that the lid  21  still is fastened to the brush when the lid  21  is opened to fill the paint in the cup  21 . As a result, the lid  21  will never be lost.  
         [0022]     The description above is a preferred embodiment of the present invention and the equivalence of the present invention is still in the scope of the claim of the present invention.
