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
The invention includes a sprinkler base 20, which has a water pipe connector 32 placed on one side, and a supporting surface 22 (as shown in
A sprinkler unit, in this embodiment, is a overflow basin 30, which comprises several sprinkler holes 31 lined up around its top part. Several water inlet holes 32 are connected to each sprinkler hole at the bottom. A column joint 33 is placed in the center of the bottom of the overflow basin 31, so that it can be locked in the slot 24 of the sprinkler base 30. By so doing, the overflow basin 30 can turn but can not separate from the sprinkler base 30. At least a positioning protruding spot 34 is placed on the side of the column joint 33, so that it is locked into the positioning grooves 25 that correspond to the slot 24 mentioned above when the overflow basin 30 is turning. The distance and numbers of the positioning groove 25 corresponds to the sprinkler hole 31 at the top of the overflow basin 30. For example, in this embodiment, there are 8 sprinkler holes 31; therefore, there are 8 positioning grooves 25. When the overflow basin 30 turns to the next sprinkler hole 31, it moves to the next positioning groove 25 by the positioning protruding spot 34 to position the basin 30. The column joint 33 comprises several elastic hooks 35 lined up in a circular shape, so that the positioning protruding spot 34 may be placed on the external side of a elastic hook 35.
A water storage space 40 is placed inside the sprinkler base 20, and the water storage space 40 is connected to the water pipe connector 21 and water outlet hole 23. Among them, the water storage space 40 of the present invention has a slot 24 in the center of the sprinkler base 20 that is designed in a circular shape. The water storage space 40 can be formed by sprinkler base 20, such as a blowing method. Moreover, the sprinkler base 20 can also be made by a top and a bottom cover, such as high frequency press or sealed ring, to shape the water storage space 40.
Through the above structure and design, the operation of the present invention is explained herein.
The primary feature of the present invention is the water storage space 40 added inside the sprinkler base 20. By this invention, as shown in
Another feature of the present invention is that the positioning grooves 25 are lined up around the wall of the slot 24 of the sprinkler base 20, and a positioning protruding spot 34 is placed on the side of the column joint 33. By this invention, the distance and numbers of the positioning groove 25 corresponds to the sprinkler hole 31 at the top of the overflow basin 30. When any of the water inlet hole 32 at the bottom of the overflow basin 30 corresponds to the water outlet hole 23 of the supporting surface 22 of the sprinkler base 20, the positioning protruding spot 34 of the column joint 33 can be locked in with the positioning groove 25 that corresponds to the slot 24, as shown in
