Description:
BACKGROUND OF INVENTION 
     Field of Invention 
     The present invention relates to a water sprayer, and more particular to a water sprayer with replaceable nozzles 
     Description of Related Art 
     Currently, the water sprayer can directly control the water output and the shape of the water spray by the components of the water sprayer. Therefore, it is widely used for gardening spraying or vehicle cleaning. A common water sprayer, as shown in  FIG.  12   , the sprayer  60  comprises a main body  61 . The front end of the main body  61  is provided with a rotatable sprinkler head  62 . The sprinkler head  62  is integrally formed with one or more sprinkler nozzles  621 . When the sprinkler head  62  is rotated, the water can be sprayed out from different sprinkler nozzles  621  which achieves the effect of changing the water output and the shape of the spray. The rear end of the main body  61  is provided with a pressing handle  63  for control, so that the water source can be controlled to open and close through whether the pressing handle  63  is pressed or not. 
     However, the above-mentioned conventional structure still has the following problems in practical applications: the spray nozzle  621  is integrally formed on the spray head  62 , so the spray shape and the rotation sequence is fixed, so that consumers cannot change the shape and rotation sequence of the splash according to their needs or preferences. Furthermore, the nozzles  621  are integrated with the water spray head  62 , so when the nozzles  621  is damaged or blocked, the nozzles  621  cannot be replaced separately, and the entire water spray head  62  or even the entire water spray gun  60  needs to be directly replaced, which is wasteful in use. 
     Therefore, it is desirable to provide a water sprayer with replaceable nozzles to mitigate and/or obviate the aforementioned problems.

The supplying tube  122  is connected to the handle portion  11  configured to be connected to a water supply, therefor water passes through the handle portion  11  to enter into the supplying tube  122 . The locking socket  123  is disposed in the extended chamber and protrudes from the extended chamber as a front open edge  124 . The guiding lid  20  has a central hole  21 , a first hole  22 , a second hole  23  and at least one third hole  24 . The first hole  22 , the second hole  23  and the third hole  24  are evenly arranged around the central hole  21 , the first hole  22  and the second hole  23  are respectively connected and surrounded by a first neck  25  and a second neck  26  on the guiding lid  20 . The central hole  21  is configured to accept the locking socket  123  such that a back side of the guiding lid  20  pushes against an front open edge  124  of the extended chamber  12  for assembly onto the main body  10 . Since the guiding lid  20  is rotatable, the supplying tube  122  can be selectively aligned with the first hole  22 , the second hole  23  or the third hole  24 . The front end of the first neck  25  and the second neck  26  are exposed, and a screen  251  is attached onto the first neck  25 . The first nozzle  30  and the second nozzle  40  each have a cylindrical body  3141 , and each cylindrical body  3141  has a plurality of different spray holes  3242  at a front end and a stopping edge  3343  at a rear end. The output head  50  has an assembling aperture  501  at center, and a first sleeve hole  502 , a second sleeve hole  503  and at least one third sleeve hole  504 . Each of the first sleeve hole  502 , the second sleeve hole  503  and the third sleeve hole  504  has a flange  505 , when the first nozzle  30  and the second nozzle  40  are respectively placed into the second sleeve hole  503  and the third sleeve hole  504 , so the stopping edge  3343  of the respective cylindrical body  3141  and the flange  505  restrict each other. Therefore, the first nozzle  30  and the second nozzle  40  can only protrude its front end out from the output head  50 . The assembling aperture  501  accepts the locking socket  123 , and a screw  51  locks the locking socket  123  to assemble the output head  50  onto the fitting lip  12  of the main body  10 , and the output head  50  covers the guiding lid  20 . The front end of the flange  505  and the second neck  26  are clamped to the screen  251  and the first nozzle  30  respectively, and the front end with the third hole  24  of the guiding lid  20  helps the rear end of the second nozzles  40  to be aligned. Because the first neck  25  and the second neck  26  protruding from the front end of the guiding lid  20  are inserted into the first sleeve hole  502  and the second sleeve hole  503  respectively, when the output head  50  is assembled, the output head  50  and the guiding lid  20  can move simultaneously, so that when the output head  50  rotates, the guiding lid  20  is driven to rotate too. Since the output head  50  can be disassembled, the output head  50  and the guiding lid  20  can also be separated smoothly in order to change the first nozzle  30  or at least one second nozzle  40  with different sprayer shapes. Therefore, the water sprayer can be more flexible and changeable, and more tailored to individual conditions. 
     Moreover, the fitting lip  121  is configured to have a reduced diameter corresponding to the extended chamber  12 . 
     Furthermore, the main body has a control knob  13  for controlling water flow. 
     In addition, the first neck  25 , the screen  251  and the first sleeve hole  502  all have a corresponding fan shape. 
     Additionally, the first nozzle  30  is a foam nozzle  301  having a plurality of apertures  311  on the cylindrical body  31  and at least one aerating mesh  34  and a mesh spray hole  32  disposed at a front end of the cylindrical body  31 . Using the apertures  311  to introduce the air and break the water flow, it makes the water contain a lot of bubbles. Then, the foamy water is sprayed from the spray hole  32  of the foam nozzle  301 , which can create a large flow illusion with a actual small flow to achieve the effect of saving water, please refer to  FIG.  6    and  FIG.  7   .
