Description:
BACKGROUND OF THE INVENTION 
   (a) Technical Field of the Invention 
   The present invention relates to comb structure, and in particular, a comb structure which can function as a comb for dyeing hair. 
   (b) Description of the Prior Art 
     FIGS. 8 and 9  depict a conventional comb structure having a combing disc  70  and a handle  80 . The combing disc  70  is made of hard material and the center thereof is a cavity  71  having an opening at one end mounted with a connector. One flat side face of the combing disc  70  upward extends to form a hollow binding tube  72  which is used to discharge hair dye and is also used to comb hair. On the top of the hollow binding tube  72 , a hood  74  is mounted so as to seal the opening of the hollow binding tube  72 . 
   The handle  80  has a chamber  81  contained an air sac  90 . One end of the air sac  90  is an outlet for the end portion of the handle  80  to protrude out, and a connector  82  is mounted thereto. 
   In dyeing hair, the handle  80  and the combing disc  70  are separated and a dyeing agent  91  is poured to the hollow cavity  71  from the connector  73 , after that the combing disc  70  and the handle  80  are connected with the connector  73  ( 82 ). The hood  74  is then opened, as shown in  FIG. 10 , press the air sac  90  protruded from the handle  80  and the hair dye  91  is discharged via the opening of the binding tube  72 . The hairs are dyed and combined. 
   The drawbacks of the conventional comb are as follows:
         1. There are residues on the combing disc after the hair dyes are being used, and cleaning of the combing disc is troublesome, and dandruff will block the binding tube.   2. The combing disc cannot be used for dyes of different color.   3. Squeezing the air sac will not evenly discharge the dyes and therefore the quality of dyeing is poor.   4. If the opening of the binding tube is too large, a large paste of dye is discharged and may stick onto the hair, which may not be able to clean off easily.   5. The combing teeth of the conventional comb are not dense and therefore the combing treatment is poor.       

   SUMMARY OF THE INVENTION 
   Accordingly, it is an object of the present invention to provide a multi-functional hair-dyeing comb structure having an elongated housing containing a chamber with an installation slot at the upper portion thereof, a hole being formed between the chamber and the installation chamber and a guiding rod formed at the hole, characterized in that one end of the housing is a control chamber having a press switch, and a motor is provided at the chamber connected to the press switch, and the other end of the housing is a main shaft gear connected to a transmission gear module; and a rotating disc is mounted at the external of the guiding rod, and the circumferential edge is provided with teeth in engagement with the transmission gear module; and a press disc mounted onto the guiding rod urging the rotating disc, and the external side face of the combing teeth seat is at least is a main binding tube having a hollow opening; and the inner side face of the combing teeth seat is provided with a liquid sac and the combing teeth seat is mounted within the installation slot of the housing; whereby when the press switch is pressed, the transmission gear module drives the rotating disc to push the press disc moving along the guiding rod, and the press disc urges the liquid sac so that the dyeing agent is evenly squeezed out.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims. 
   Referring to  FIGS. 1 ,  2 , and  3 , there are shown a hair-dyeing comb having an elongated housing  10 , as shown in  FIG. 3 . The housing  10  is formed from two sides plates  100 ,  101  and a chamber  11  is provided to the housing  10 . The top portion of the chamber  11  is an installation slot  12  and a hole  16  is provided between the chamber  11  and the installation slot  12 . A guiding rod  15  is provided at the hole  16 , and the other end of the housing  10  is a control chamber  13  having mounted with a press switch  14 . 
   A motor  20  is positioned in the chamber  11  having one end connected to the press switch  14  of the control chamber  11 . The main shaft gear  21  at the other end of the control chamber  13  is connected to a transmission gear module  30 . 
   A rotating disc  40  is mounted externally to the guiding rod  15  and the circumferential edge is provided with teeth  41  which is in engagement with the gear module  30 . 
   The end portion of a press disc  50  is a push face  51  and the other two ends are mounted onto the guiding rod  15  and urges the rotating disc  40 . 
   A combing-teeth seat  60  has the size of the installation slot  12  of the housing  10 , and the external side face is provided with at least a main binding tube  61 , dense combing teeth  63 , and very dense combing teeth  64 . The opening  62  of the main binding tube  6  is at the side of the outer ends and the inner side face of the combing-teeth seat  60  is a liquid sac  65 , and a dyeing agent  67  is contained in the liquid sac  65 . The combing-teeth seat  60  has at least one side mounted with an elastic button  66  such that the combing teeth seat  60  can be snapped on to the installation slot  12  of the housing  10  by the elastic button  66 . 
   Referring to  FIGS. 3 , and  4 , when in application, the press switch  14  of the housing  10  is depressed, the motor  20  is initiated and by means of the transmission gear module  30 , the press disc  50  of the rotating disc  40  is driven to move along the guiding rod  15 , and the push face  51  of the press disc  50  urges the liquid sac  65  of the installation slot such that the dyeing agent  67  within the liquid sac  65  is squeezed out from the opening  62  at the end portion of the main binding tube  61 . Thus, the flowrate of the dyeing agent can be controlled and will not be dropped onto the root of the hairs. 
   Referring to  FIGS. 1 , and  5 , the opening  62  are in pair, and are in the axial direction of the main binding tube  61 . When hairs A are combined between the main binding tube  61 , the dyeing agent  67  directly dyes the hair A and will not drop. Referring to  FIG. 6 , the hairs A are dyed at the main binding tube  61  and are supported by the dense combing teeth  63  and are combed by the very dense combining teeth  64 . Thus, the hairs A are dyed, supported and treated. 
   Referring to  FIG. 7 , the lengths of the main binding tube  61 , dense combing teeth  63  and the very dense combing teeth  64  are in from the largest length to the shortest or the ends are in arch-shaped. For each dyeing, the hairs A are first dyed at the main binding tube  61 , via the dense combing teeth  63  and the very dense combing teeth  64 , and the arch shape conforms to the profile of the head. 
   The advantages of the present invention are
         1. When dyeing agent has been used up, the combing teeth seat having a liquid sac can be detached and replaced. The problem on residue will not occur.   2. As the rotating speed of the transmission gear driven by the motor is at a constant speed, the press disc squeezes the liquid sac evenly and the force exerted is even, and the dyeing process is smooth. Thus, the dyeing of hair is smooth.   3. The comb structure allows free use of dyes of different color.   4. The interior of the main binding tube will not be blocked easily.   5. The opening of the main binding tube is at the side of the end portion thereof, and therefore, the dye discharged is rather even, and will not drip onto the root of the hair. Further, the flowrate of dye can be easily controlled.   6. The combing-teeth seat of the present invention can be used as a comb.       

   It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. 
   While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
