DETAILED DESCRIPTION

With reference toFIGS. 1 to 3, a sprinkler structure according to a first embodiment of the present invention comprises: an accommodation tube10, multiple water outflow zones11separately defined on a middle section of a top of the accommodation tube10, multiple grooved partitions12arranged on two ends of the top of the accommodation tube10respectively, multiple first water gathering zones13and multiple second water gathering zones14which are defined inside the multiple grooved partitions12individually, wherein a bottom of each of the multiple first water gathering zones13is flat and has a first inlet131defined thereon and communicating with the accommodation tube10, and a bottom of each of the multiple second water gathering zones14has a first inlet141defined thereon and communicating with the accommodation tube10. The accommodation tube10includes multiple first guide orifices15arranged on a first peripheral side thereof so as to define a first shoulder151, and the accommodation tube10includes multiple second guide orifices16arranged on a second peripheral side thereof so as to define a second shoulder161, wherein each of the multiple first guide orifices15is located below two sides of each first water gathering zone13and communicates with the accommodation tube10, and each of the multiple second guide orifices16is located below two sides of each second water gathering zone14and communicates with the accommodation tube10, hence a control bar20is rotatably connected and horizontally moves in each first guide orifice15and each second guide orifice16. Referring toFIG. 4, the control bar20includes two fitting sections21respectively arranged on two ends thereof and fitting with two push elements22, wherein each of the two push elements22has a column221extending therein so as to fit with each fitting section21of the control bar20, and a notch222is defined by an inner wall of each push element22and an outer wall of the column221so as to connect with each first guide orifice15or each second guide orifice16, hence the column221of each push element22is located between each fitting section21and each first guide orifice15or between each fitting section21and each second guide orifice16, and the column221of each push element22separates a limitation space A from the first shoulder151or the second shoulder161so as to control the control bar20to move horizontally and to be limited by each push element22. The control bar20includes a plane23defined on a top thereof, an inflow chamber24formed in a hole shape and passing through a middle section of the control bar20, a receiving portion25formed on a side of the inflow chamber24so as to house a stop element26made of a flexible rubber, such that the stop element26abuts against a bottom of each first water gathering zone13and of each second water gathering zone14. The receiving portion25includes a square coupling zone251formed on a top thereof, a connection section252defined on a middle section of the receiving portion25and its diameter is less than the square coupling zone251, and a through orifice253defined on a bottom of the receiving portion25and its diameter is more than the connection section252. The stop element26is square and is accommodated in the square coupling zone251, and the stop element26has a foot261extending outwardly from a bottom thereof so as to fit with the connection section252. The control bar20further includes two slots27respectively defined on two sides thereof so as to accommodate two seal rings28which individually abut against each first guide orifice15and each second guide orifice16, thus avoiding water leakage out of the accommodation tube10. The accommodation tube10further includes an elongated lid30connected on the top of the accommodation tube10and made of plastic material so as to cover and separate the multiple water outflow zones11, the multiple first water gathering zones13, and the multiple second water gathering zones14. The elongated lid30includes multiple nozzle elements31formed on a top thereof, any two adjacent of the multiple nozzle elements31are obliquely and separately arranged on two sides of the top of the elongated lid30, each first water gathering zone13communicates with one or more than one nozzle element31, and each second water gathering zone14communicates with one or more than one nozzle element31. A fixing plate40is mounted on the elongated lid30, and a cap50covers the accommodation tube10, wherein the fixing plate40includes multiple first apertures41formed thereon and corresponding to the multiple nozzle elements31, and the cap50includes multiple second apertures51formed thereon and corresponding to the multiple nozzle elements31, such that the multiple nozzle elements31respectively extend out of the fixing plate40and the cap50via the multiple first apertures41and the multiple second apertures51. The fixing plate40is connected on the accommodation tube10in an ultrasound adhesion manner, and a tip of each of the multiple nozzle elements31is higher than a tilted peripheral side of an upper end of each nozzle element31, two edges of the accommodation tube10are individually a water supply segment and a closed segment, wherein the water supply segment of the accommodation tube10is driven by a control assembly (not shown) so as to actuate the accommodation tube10to rotatably spray water at any angles.

As shown inFIGS. 3 and 4, when the control bar20is pushed to each push element22on the first peripheral side of the accommodation tube10along each first guide orifice15and each second guide orifice16of the accommodation tube10so as to be stopped by the second shoulder161, the inflow chamber24simultaneously communicates with the first inlet131of each first water gathering zone13and the second inlet141of each second water gathering zone14so that the water sprays out of each nozzle element31from the accommodation tube10via each of the multiple water outflow zones11and via the inflow chamber24of the control bar20, the first inlet131of each first water gathering zone13, and the second inlet141of each second water gathering zone14, thus spraying the water out of each nozzle element31at a large area. As illustrated inFIG. 5, when each push element22of the control bar20is pushed to the second peripheral side of the accommodation tube10along the limitation space A until the stop element26stops the first inlet131of each first water gathering zone13, the water does not flow into the first inlet131, and the inflow chamber24merely communicates with the second inlet141of each second water gathering zone14so that the water gathers in each second water gathering zone14via the inflow chamber24and sprays out of each nozzle element31above each second water gathering zone14. In the meantime, the water is isolated by each grooved partition12so that the water does not flow into each first water gathering zone13and each nozzle element31above each first water gathering zone13is closed, thus spraying the water out of each nozzle element31at a small area. Furthermore, the water pushes the stop element26from the accommodation tube10via the through orifice253of the receiving portion25so that the stop element26is pushed by a water pressure to matingly contact with the first inlet131of each first water gathering zone13, thus avoiding water leakage. With reference toFIG. 6, when each push element22of the control bar20is further pushed to be stopped by the first shoulder151of the multiple first guide orifices15, the first inlet131of each first water gathering zone13and the second inlet141of each second water gathering zone14are closed by the stop element26so as to stop the water, hence each nozzle element31of the first water gathering zone13and of the second water gathering zone14is closed so as to spray the water in a smaller area. Preferably, the stop element26is pushed by the water pressure to matingly contact with the first inlet131of each first water gathering zone13and the second inlet141of each second water gathering zone14so as to prevent the water flowing into each first water gathering zone13and each second water gathering zone14. The receiving portion25of the control bar20accommodates the stop element26, and the inflow chamber24communicates with the first inlet131of each first water gathering zone13and the second inlet141of each second water gathering zone14so as to control a number of the multiple nozzle elements31where the water sprays out.

Referring toFIGS. 7 and 8, in a second embodiment, the accommodation tube10does not include the multiple grooved partitions12of the first embodiment and includes multiple water gathering zones13′, each of the multiple water gathering zones13′ has an inlet131′ defined on a bottom thereof and matching with the control bar20, and each water gathering zone13′ communicates with two or more than two nozzle elements31, when the control bar20is pushed to the second peripheral side of the accommodation tube10until the inflow chamber24communicates with the inlet131′ of each water gathering zone13′, the water sprays out of each nozzle element31of each water outflow zone11from the water supply segment101of the accommodation tube10, and the water flows into each water gathering zone13′ so as to spray out of each nozzle element31′ of each water gathering zone13′ from the inlet131′ via the inflow chamber24of the control bar20, hence the water sprays out of each nozzle element31′ in a large area. As shown inFIG. 9, when the each push element22of the control bar20is pushed to the second peripheral side of the accommodation tube10, each water gathering zone13′ is closed by the stop element26so that when the water is stopped flowing into each water gathering zone13′, each nozzle element31of each water gathering zone13′ is closed, thus spraying the water in a small area.

Note that the specifications relating to the above embodiments should be construed as exemplary rather than as limitative of the present invention, with many variations and modifications being readily attainable by a person of average skill in the art without departing from the spirit or scope thereof as defined by the appended claims and their legal equivalents.
