   FIELD OF THE INVENTION 
   The present invention relates generally to a garden hose nozzle, and more particularly to a garden hose nozzle with a whirling effect. 
   BACKGROUND OF THE INVENTION 
   The conventional garden hose nozzle is typically designed with a fixed direction, so manual operation shall be required to change its spraying direction. When the spraying objects are located in a higher position, the end-user will find it difficult to hold the hose nozzle continuously. And, as the direction of hose nozzle cannot be adjusted, it is unlikely to place the hose nozzle in a fixed position to spray water automatically. Although an adjustable structure of hose nozzles has been developed by some designers, it does not apply to garden hose nozzles owing to the limited structure of a wand nozzle. 
   Therefore, based upon aforementioned disadvantages of garden hose nozzle, this industry shall assume the responsibility to make some pioneering R&amp;D and innovations so as to offer a utility model with whirling design. 
   BRIEF SUMMARY OF THE INVENTION 
   The present invention is design to: 
   Provide an innovative garden hose nozzle with a whirling design. This is a preferred option of this Industry in conformity with the requirements of new patent. 
   Based upon this modified structure design, the hose nozzle with similar grip state can offer flexible applications through variable spraying angle of its whirling design, with the purpose of meeting the customer demands.

   DETAILED DESCRIPTION OF THE INVENTION 
   The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings. 
   As shown in  FIGS. 1–4 , a garden hose nozzle embodies the present invention. 
   A hose nozzle  10 , with its outer flank provided with a grip  20  and its back end provided with a hose connecting end  11 . The hose connecting end  11  is connected to a conduit  12  within the hose nozzle  10 , which is linked to a water valve  13 . The water valve  13  is equipped with a water control post  14  that is subjected to the control of a control button  30  outside the hose nozzle  10  for its start-up/close state. A spring  141  is placed between the bottom of the water control post  14  and the lower wall of the water valve  13 , so as to enable the water control post  14  to eject toward the control button  30  until a flange  142  of the water control post  14  stops at the shoulder  131  of the water valve  13 ; 
   A rotary outlet  40 , provided at the front end of the hose nozzle  10 . The end surface of the rotary outlet  40  is mounted with a spraying hole  41 . As an independent component, the rotary outlet  40  is available with a connector  42  at one side of the hose nozzle  10 . There is a water hole  43  within the connector  42  linking to the spraying hole  41 . To maintain an insert notch  15  as shown in  FIGS. 4 and 5  at the hose nozzle  10 &#39;s one side adjacent to the water valve  13 , the insert notch  15  shall be available with a passage notch  16  connecting the water valve  13 . And, the start-up and close state of the passage notch  16  shall be subjected to the control of the water control post  14 . The front end of the hose nozzle  10  is provided with a passage notch  17 , where the connector  42  of the rotary outlet  40  can cross the hose nozzle  10 , and then the above-mentioned insert notch  15  so that the connector  42  can rotate round the insert notch  15  to form a whirling state. After the fixation by localizers, a whirling state that the connector  42  and the rotary outlet  40  rotate round the insert notch  15  as shown in  FIG. 5  will take shape, wherein the insert notch  15  functions as the rotation center of the connector  42  when the connector  42  rotates round the insert notch  15 , while the rotating angle is subjected to the limitation of the passage notch  17 ; 
   An arc dent  44  may be provided at one side of the rotary outlet  40  facing the hose nozzle  10 , thus enabling the front end of the hose nozzle  10  to be provided with a shape of an arc convex  18 . 
   As shown in  FIG. 6 , the arc dent  44  can be provided with some separate concavities  45  along the whirling direction of the rotary outlet  40 , so a flexible button  19  shall be mounted at the arc convex  18  of the front end of airbrush so as to push in a corresponding concavity  45  along with the rotation of the outlet  40 , with the aim of serving the purpose of division and positioning. 
   The grip  20  at the outer flank of the hose nozzle  10  is an integral part of carrying handle. The front end of the grip  20  is connected to the water control post  14  corresponding to the hose nozzle  10  while the back end of the grip  20  shall be of a suspended type, so as to place the control button  30  at the fore part of the grip  20 . The control button  30  comprises a board base  31 , a button  32  and a cover plate  33 , of which the board base  31  can be connected to two side walls at the fore part of the grip  20  via a shaft bolt  34 . The bottom of the board base  31  is available with a braking surface  35  corresponding to the top of the water control post  14 . To offer a convenient press/push, the button  32  will protrude an opening  21  at the top of the fore part of the grip  20 . The cover plate  33  will protrude the front side of the button  32  to cover the opening  21 . 
   The localizer of the connector  42  and insert notch  15  comprises a screw column  51  at the center of insert notch, a punching hole  52  at the center of the connector  42  and a bolt  53 . When the bolt  53  is screwed into the screw column  51  after crossing the punching hole  52 , it can fix the connector  42  and insert notch  15 . 
   The embodiment of the present invention described above can apply to the following conditions. 
   As shown in  FIG. 2 , where the rotary outlet  40  is in a watertight state, the top of the water control post  14  has not yet contacted the braking surface  35  at bottom of the control button  30 , so the passage notch  16  is not connected to the water valve  13 , the water is inaccessible to the outlet  40 . 
   As shown in  FIGS. 3–4 , when the end-user press the control button  30 , the braking surface  35  will push the water control post  14  and make it shift downwards. In such case, the passage notch  16  is connected to the water valve  13 , so the water can be accessible to the spraying hole  41  of the rotary outlet  40  through the conduit  12 , water valve  13 , passage notch  16  and water hole  43  of the connector  42 . 
   Additionally, the spraying hole of the present invention&#39;s garden hose nozzle is available in both a flower-like spraying hole  41  (as shown in  FIG. 1 ) and a single-hole spraying hole  41 B (as shown in  FIG. 9 ).
