     FIELD OF THE INVENTION  
      The present invention relates generally to a sprinkler, and more particularly to a spray pattern guide structure of the sprinkler.  
     BACKGROUND OF THE INVENTION  
      As shown in  FIG. 3 , a spray head of the prior art comprises a spray-pattern dial  40  and a spray pattern scale  41  which is formed of a series of pattern marks expressed by English words. The spray pattern scale  41  is of course useful in an English-speaking country. In another words, the spray pattern scale  41  cannot be understood universally.  
     BRIEF SUMMARY OF THE INVENTION  
      The primary objective of the present invention is to provide a spray head with a series of symbols representing the spray patterns. The symbols are corresponding in location to a series of jet nozzles of the spray head and are universally understood.  
      The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION  
      As shown in  FIGS. 1 and 2 , a spray head  10  embodied in the present invention comprises a spray pattern dial  20 , a series of spray pattern symbols  30 , and an indicator  11 .  
      The spray pattern dial  20  is provided with a plurality of jet nozzles  21  capable of spraying water in various patterns, which are represented by the symbols  30 . In another words, the symbols  30  are corresponding in location to the jet nozzles  21 .  
      In operation, the spray pattern dial  20  is so turned that a desired symbol  30  is aligned with the indicator  11 , the water is sprayed by a specific jet nozzle  21 .  
      The symbols  30  form a pattern scale  22  of the present invention. The symbols  30  may be printed or indented.  
      The embodiment of the present invention described above is to be regarded in all respects as being illustrative and nonrestrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scopes of the following claims.
