Title: Water sprayer head

Description:
BACKGROUND OF INVENTION 
     Field of Invention 
     The present invention relates to a water sprayer head. 
     Description of Related Art 
     Normally, it is necessary to water frequently in gardening work to prevent plants from dying due to lack of water, but plants are usually planted in a wide range or far from the water source, so water pipes connecting the gardening spray gun are often used in the watering process. Although the typical known gardening spray gun usually has a variety of different spray shapes to choose, the spray gun still cannot spray mist for certain plants, which is also impossible to achieve more water-saving and more uniform spread. 
     Therefore, it is desirable to provide a water sprayer head to mitigate and/or obviate the aforementioned problems. 
     SUMMARY OF INVENTION 
     An objective of present invention is to provide a water sprayer head, which is capable of improving the above-mention problems. 
     In order to achieve the above mentioned objective, a water sprayer head has a guiding base and a positioning cover. The guiding base has a main body with a plurality of guiding columns, each guiding column having a respective central guiding hole and at least one distributing aperture at a front end connected to the guiding hole, a diameter of the distributing aperture being smaller than a diameter of the guiding hole. The positioning cover has a front end portion and a rear end portion, the rear end portion has a plurality of sleeve holes corresponding to the number and positions of the guiding columns, each sleeve hole has at least one aperture passing through the front end portion and having a diameter smaller than the diameter of the respective distributing aperture. 
     Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
     Please refer to  FIGS. 1 and 2 . The water sprayer head comprises a guiding base  10  and a positioning cover  20 . The guiding base  10  has a main body  11  with a plurality of guiding columns  12 , each guiding column  12  having a respective central guiding hole  13  and at least one distributing aperture  14  at a front end connected to the guiding hole  13 . When water enters into the guiding hole  13  through the guiding column  12  and exits from the distributing aperture  14 . A diameter of the distributing aperture  14  is smaller than a diameter of the guiding hole  13 , so the water is more refined. The positioning cover  20  has a front end portion and a rear end portion, the rear end portion has a plurality of sleeve holes  21  corresponding to the number and positions of the guiding column  12 . Each sleeve hole  21  has at least one micro aperture  22  passing through the front end portion and having a diameter smaller than the diameter of the respective distributing aperture  14 . The micro aperture  22  refines the water even more before spraying it out, so the water sprayer head can provide misty spray. 
     Furthermore, the main body  11  of the guiding base  10  is a round disk. 
     Moreover, the rear end portion of the positioning cover  20  is provided with a groove  23  configured to accept the main body  11  of the guiding base  10 , as shown in  FIG. 4 . 
     In addition, t a periphery of the positioning cover has a flange  24  for securing on to water equipment  30 . 
     Also, the water equipment  30  is a gardening sprayer. 
     Additionally, the water equipment  30  is a long spray gun. 
     As well, the water equipment  30  is a ground sprinkler. 
     Moreover, the guiding column  12  of the guiding base  10  and the sleeve hole  21  of the positioning cover  20  both have a number of three. 
     In addition, each sleeve hole  21  has three micro apertures  22  passing through the front end portion of the positioning cover  20 . 
     Likewise, the number of the micro aperture  22  can be changed to change the flux and distribution area of the water sprayer head. 
     In actual use, the water sprayer head is installed on the water equipment  30 . In this embodiment a gardening multi-stage spray gun is used as an example for the water equipment  30 , but it is not limited to this. Please also refer to  FIG. 3  to  FIG. 5 , the guiding holes  13 , the distributing apertures  14  and the micro apertures  22  together provide a water channel for the water to pass through, and the difference diameters of the holes and the apertures, the water can be sufficiently refined, and then sprayed in a mist-like spray. Therefore, it can prevent the spray particles from being too large to damage or over-water the plants, and it can also achieve more water-saving and more uniform distribution, so that the use of the water sprayer head can be more in line with the urgent needs of consumers. 
     Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
