Title: Water spray nozzle

Description:
BACKGROUND 
     Aspects of the present invention relate to a water spray nozzle. 
     Conventional water spray nozzles have a switch disposed on its body. The letting out of water is controlled by the switch through a valve. Conventional water spray nozzles are switched on or off by the switch, which only has a single function. In order to make the water spray nozzle multi-functional, a switchable switch is disposed on the water spray nozzle for allowing different ways of water spraying as disclosed in U.S. Pat. No. 6,151,729. 
     SUMMARY 
     However, in conventional switchable switches, the position of a valve is changed by switching method. Thus, there are only two different directions, which are very limited. Furthermore, the switchable switch can be mistakenly pressed to change the way of outlet of water. Therefore, it is inconvenient in usage. 
     A water spray nozzle embodying aspects of the present invention comprises a handle body with a handle portion and a head portion, the handle portion having a water inlet hole and a water outlet hole. The nozzle includes a switch valve disposed between the water inlet hole and the water outlet hole, a water outlet compartment disposed in the head portion for connecting with the water outlet hole, an opening disposed at an end of the water outlet compartment, an axial hole disposed at another end opposite to the opening, the axial hole having a limitation groove disposed inside the water outlet compartment, and a preset quantity of limitation slots disposed axially and concavely inside the limitation groove. The nozzle also includes a switching rod disposed inside the axial hole, a central of the switching rod having a guiding piece slidably disposed in the limitation groove, guiding ribs disposed on a circumference of the guiding piece, a slant guiding surface disposed at an end of the guiding rib, the guiding ribs being axially limited inside the limitation slots, the switching rod having a direction switching piece disposed at the end of the water outlet compartment, and a preset quantity of slant protruded portions disposed around the direction switching piece. Further, the nozzle has a switching disk disposed on a bottom of the water outlet compartment, a switching hole penetrated through a center of the switching disk, the switching disk being disposed around the switching rod between the guiding piece and the direction switching piece, switching ribs protrudedly disposed inside the switching hole, the switching rib having a slant switching surface disposed near the guiding rib and opposite to the slant guiding surface, a preset quantity of slant switching protruded portions disposed outside the switching hole near the direction switching piece for meshing with the slant protruded portions, and a plurality of switching water holes disposed around a circumference of the switching disk. The nozzle further includes a water passage switching piece concavely disposed with a recess at a center, the recess being provided for accommodating the direction switching piece of the switching rod and the slant switching surface of the switching disk, a preset quantity of water outlet holes disposed around a circumference of the water passage switching piece, and the water outlet holes and the switching water holes being disposed in a same radial direction so that the switching water holes being selectively superimposed with the specific water outlet holes and includes two elastic support elements respectively disposed between the bottom of the water outlet compartment and the switching disk, and between the direction switching piece and the recess. 
     The water spray nozzle of the present disclosure can be switched on or off through the switch valve of the handle body. Simply press the switching rod for switching between the ways of usage. The guiding piece of the switching rod drives and rotates the switching disk. The positions of the switching water holes are changed by having the slant protruded portions to mesh with the slant switching protruded portions. After the positions are changed, the switching water holes can be superimposed with different water outlet holes for changing the way of outlet of water. It is easy to use and speedy for switching direction. The switching rod is disposed at the back of the head portion and therefore is ergonomically designed. 
     The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings. 
     Other objects and features will be in part apparent and in part pointed out hereinafter.

     The two elastic support elements  50  are respectively disposed between the bottom of the water outlet compartment  121  and the switching disk  30 , and between the direction switching piece  22  and the recess  41 . 
     In order to further explain the structures and characteristics of the present invention, as well as the technical means and expected effects; the ways of usage are specifically described hereunder for in-depth understanding. 
     Please refer to  FIGS. 1 to 4 . When water is needed, simply press the switch valve  13  for connecting the water inlet hole  111  with the water outlet hole  112 . Water is flowed from the water inlet hole  111  to the water outlet hole  112 . Then the water is further flowed from the water outlet hole  112  to the water outlet compartment  121  of the head portion  12 . Finally, the water is flowed to reach the opening  122 . 
     For switching the water flowing direction, simply press the switching rod  20  so that the slant protruded portions  221  of the direction switching piece  22  will not limit the slant switching protruded portions  32 , and the switching disk  30  can turn freely. Then, the slant guiding surfaces  212  of the guiding ribs  211  of the guiding piece  21  are connected with the slant switching surfaces  312  on top ends of the switching ribs  311  of the switching disk  30 . The switching disk  30  turns at a certain degree. Meanwhile, the elastic support element  50  disposed between the recess  41  and the direction switching piece  22  generates an elastic force to cause the switching rod  20  to generate a resilient effect. When the switching rod  20  rebounds, because the switching disk  30  has already turned at a certain degree; the slant protruded portion  221  will mesh with the other slant switching protruded portion  32  to cause the switching disk  30  to turn at 90°. The change of the position of the switching disk  30  causes the switching water holes  33  to connect with the different water outlet holes  42 . Water will flow out from the water outlet holes  42  which are connected with the switching water holes  33 . The water will flow towards the central passages  43  or the circular passages  44 . The water flowed towards the opening  122  is originated from the central passages  43  or the circular passages  44 . The water is stopped by the water stoppers  34  for the water outlet holes  42  which are not connected with the switching water holes  33 . 
     The switching rod  20  is used for switching between different ways of outlet of water. The switching rod  20  rebounds back to its original position after the switching is done. Simply press the switching rod  20  again for switching, and is not easily and mistakenly pressed to change direction of water flow. The switching is achieved simply by pressing the switching rod  20 . Therefore, it is convenient and easy in usage. Furthermore, the ergonomic design of the switching rod  20  disposing in the head portion is convenient for users to press while holding the handle portion.
