Description

Technical Field

[0001] The utility model relates to the field of bathroom products, in particular to a water sprayer. Background Art

[0002] Existing large public hand-washing troughs and urinals usually need to be equipped with a water outlet device for cleaning the trough wall to keep the equipment clean. For example, the Chinese patent with publication number CN205444385U discloses a urinal, which includes a stainless steel urinal body, a urinal provided on the stainless steel urinal body, a urine outlet at one end of the urinal, a sealed stainless steel flush trough on the upper part of the stainless steel urinal body, and a row of water outlet holes distributed at the bottom of the stainless steel flush trough that can flow along the surface wall of the stainless steel urinal body to the urinal. The upper part of the stainless steel flush trough is provided with a water inlet. If the water inlet is directly connected to the water pipe, the water in the water pipe will flow vertically downward to the flush trough under the action of gravity. After the water flows to the flush trough, it will flow to the left and right sides of the flush trough. The flushing speed on the left and right sides of the flush trough will be slower than that in the middle of the flush trough, and may result in less water output on the left and right sides of the flush trough. In view of this, the present invention proposes a water sprinkler to solve the above problems. Utility Model Content

[0003] The utility model overcomes the deficiencies of the above technologies and provides a water sprayer.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A water sprinkler includes a pipe body, a water outlet cover connected to the bottom of the pipe body, a protrusion located inside the pipe body is provided at the center of the water outlet cover, a plurality of water outlet holes are provided on the water outlet cover around the protrusion, and the protrusion is used to change the direction of water flow so that water flows to the water outlet holes; an annular pressure surface is provided on the outer surface of the pipe body, and a first nut is connected to the outer surface of the pipe body through a thread, and the first nut is located above the annular pressure surface.

[0006] Preferably, the inner surface of the tube body is used for connecting to a water pipe.

[0012] Preferably, the annular pressure surface is located on the top of the water outlet cover.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The internal bumps of the sprinkler of this utility model can effectively change the direction of water flow, so that water flows to each water outlet. Moreover, the water flow direction changes from vertically downward to inclined downward flow from the bumps toward the periphery, which increases the water spraying area of ​​the sprinkler. When this sprinkler is installed in the existing urinal, the water flow can be more evenly distributed throughout the flush trough, thereby ensuring uniform water discharge from the flush trough.

[0015] 2. The utility model installs the sprinkler on the urinal or wash basin by the first nut and the annular pressure surface. Under the dual fixing action of the first nut and the annular pressure surface, the sprinkler is firmly installed on the urinal or wash basin, and the installation operation is simple.

[0016] 3. The utility model is used to connect with the water pipe through the inner surface of the pipe body, and the second nut is threadedly connected to the outer surface of the pipe body. The upper end surface of the pipe body presses the sealing ring against the sealing boss, thereby enhancing the sealing performance of the sprinkler, preventing water leakage from the pipe body, and ensuring the long-term stable operation of the sprinkler.

[0017] 4. The water outlet holes include large and small holes, with the number of small holes outnumbering the large holes. This allows the sprinkler to simultaneously meet the needs of large-area spraying and high water flow. Furthermore, the rational design of the apertures and spacing between the large and small holes ensures a more even water distribution and improves the spraying effect.

[0023] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0024] Reference Figure 1-4 , an embodiment of a sprinkler of the utility model is proposed:

[0025] A sprinkler includes a pipe body 1, wherein a water outlet cover 2 is connected to the bottom of the pipe body 1, a protrusion 21 is provided at the center of the water outlet cover 2 and is located inside the pipe body 1. The water outlet cover 2 is provided with a plurality of water outlet holes 22 around the protrusion 21. The protrusion 21 is used to change the direction of water flow so that water flows toward the water outlet holes 22. At the same time, the direction of water flow changes from vertically downward to obliquely downward flow from the protrusion 21 toward the periphery, thereby increasing the water sprinkling area of ​​the sprinkler.

[0026] like Figure 1 As shown, the water outlet hole 22 includes a large water outlet hole 23 and a small water outlet hole 24. The aperture of the small water outlet hole 24 is smaller than the aperture of the large water outlet hole 23. The large water outlet hole 23 can increase the water output of the sprinkler, so that the sprinkler can simultaneously meet the needs of large-area water spraying and large water flow.

[0027] The diameter of the large water outlet holes 23 is 10-16 mm, and the diameter of the small water outlet holes 24 is 1.5-3 mm. The inner diameter of the tube body 1 is 35-42 mm. The spacing between adjacent small water outlet holes 24 is 1.2-5 mm; the spacing between adjacent large water outlet holes 23 is 8-13 mm. The rational design of the diameter and spacing of the large and small water outlet holes 23 and 24 ensures more uniform water distribution and improves the spraying effect.

The sprinkler also includes a second nut 4, which has a threaded hole 41. A sealing boss 42 is provided within the threaded hole 41, and a sealing ring 43 is mounted on the sealing boss 42.

[0029] Specifically, the pipe body 1 , the water outlet cover 2 , and the annular pressing surface 11 are integrally formed.

[0030] The flushing trough of the utility model installed in the urinal (publication number CN205444385U) is operated as follows: Figure 4As shown, first, the annular pressing surface 11 is pressed against the lower surface of the upper stopper 5, while the pipe body 1 is passed through the water inlet. Then, the first nut 3 is threadedly connected to the outer surface of the pipe body 1, while the first nut 3 is pressed against the upper surface of the upper stopper 5. Next, the water pipe is connected to the inner surface of the pipe body 1, and then the water pipe is passed through the second nut 4 and the sealing ring 43. The second nut 4 is threadedly connected to the outer surface of the pipe body 1. At the same time, the upper end surface of the pipe body 1 presses the sealing ring 43 tightly against the sealing boss 42, thereby sealing the threaded hole 41 and preventing water leakage from the pipe body 1, thereby ensuring the long-term stable operation of the sprinkler.

[0031] The utility model installs the sprinkler on the upper block 5 by the first nut 3 and the annular pressure surface 11 one above and one below. Under the dual fixing action of the first nut 3 and the annular pressure surface 11, the sprinkler is firmly installed on the flushing trough, and the installation operation is simple.
