Referring to FIG. 4, the control bar 20 includes two fitting sections respectively arranged on two ends thereof and fitting with two push elements 22, wherein each of the two push elements 22 has a column 221 extending therein so as to fit with each fitting section 21 of the control bar 20, and a notch 222 is defined by an inner wall of each push element 22 and an outer wall of the column 221 so as to connect with each first guide orifice 15 or each second guide orifice 16, hence the column 221 of each push element 22 is located between each fitting section 21 and each first guide orifice 15 or between each fitting section 21 and each second guide orifice 16, and the column 221 of each push element 22 separates a limitation space A from the first shoulder 151 or the second shoulder 161 so as to control the control bar 20 to move horizontally and to be limited by each push element 22. The control bar 20 includes a plane 23 defined on a top thereof, an inflow
2018201187 07 Aug 2019 chamber 24 formed in a hole shape and passing through a middle section of the control bar 20, a receiving portion 25 formed on a side of the inflow chamber 24 so as to house a stop element 26 made of a flexible rubber, such that the stop element 26 abuts against a bottom of each first water gathering zone 13 and of each second water gathering zone 14. The receiving portion 25 includes a square coupling zone 251 formed on a top thereof, a connection section 252 defined on a middle section of the receiving portion 25 and its diameter is less than the square coupling zone 251, and a through orifice 253 defined on a bottom of the receiving portion 25 and its diameter is more than the connection section 252. The stop element 26 is square and is accommodated in the square coupling zone 251, and the stop element 26 has a foot 261 extending outwardly from a bottom thereof so as to fit with the connection section 252. The control bar 20 further includes two slots 27 respectively defined on two sides thereof so as to accommodate two seal rings 28 which individually abut against each first guide orifice 15 and each second guide orifice 16, thus avoiding water leakage out of the accommodation tube 10. The accommodation tube 10 further includes an elongated lid 30 connected on the top of the accommodation tube 10 and made of plastic material so as to cover and separate the multiple water outflow zones 11, the multiple first water gathering zones 13, and the multiple second water gathering zones 14. The elongated lid 30 includes multiple nozzle elements 31 formed on a top thereof, any two adjacent of the multiple nozzle elements 31 are obliquely and separately arranged on two sides of the top of the elongated lid 30, each first water gathering zone 13 communicates with one or more than one nozzle element 31, and each second water gathering zone 14 communicates with one or more than one nozzle element 31. A fixing plate 40 is mounted on the elongated lid 30, and a cap 50 covers the accommodation tube 10, wherein the fixing plate 40 includes multiple first apertures 41 formed thereon and corresponding to the multiple nozzle elements 31, and the cap 50 includes multiple second apertures 51 formed thereon and corresponding to the multiple nozzle elements 31, such that the multiple nozzle elements 31 respectively extend out of the fixing plate 40 and the cap 50 via the multiple first apertures 41 and the multiple second apertures 51. The fixing plate 40 is connected on the accommodation tube 10 in an ultrasound adhesion manner, and a tip of each of the multiple nozzle elements 31 is higher than a tilted peripheral side of an upper end of each nozzle element 31, two edges of the accommodation tube 10 are individually a water supply segment and a closed segment, wherein the water supply segment of the accommodation
2018201187 07 Aug 2019 tube 10 is driven by a control assembly (not shown) so as to actuate the accommodation tube 10 to rotatably spray water at any angles.
[0019] As shown in FIGS. 3 and 4, when the control bar 20 is pushed to each push element 22 on the first peripheral side of the accommodation tube 10 along each first guide orifice 15 and each second guide orifice 16 of the accommodation tube 10 so as to be stopped by the second shoulder 161, the inflow chamber 24 simultaneously communicates with the first inlet 131 of each first water gathering zone 13 and the second inlet 141 of each second water gathering zone 14 so that the water sprays out of each nozzle element 31 from the accommodation tube 10 via each of the multiple water outflow zones 11 and via the inflow chamber 24 of the control bar 20, the first inlet 131 of each first water gathering zone 13, and the second inlet 141 of each second water gathering zone 14, thus spraying the water out of each nozzle element 31 at a large area. As illustrated in FIG. 5, when each push element 22 of the control bar 20 is pushed to the second peripheral side of the accommodation tube 10 along the limitation space A until the stop element 26 stops the first inlet 131 of each first water gathering zone 13, the water does not flow into the first inlet 131, and the inflow chamber 24 merely communicates with the second inlet 141 of each second water gathering zone 14 so that the water gathers in each second water gathering zone 14 via the inflow chamber 24 and sprays out of each nozzle element 31 above each second water gathering zone 14. In the meantime, the water is isolated by each grooved partition 12 so that the water does not flow into each first water gathering zone 13 and each nozzle element 31 above each first water gathering zone 13 is closed, thus spraying the water out of each nozzle element 31 at a small area. Furthermore, the water pushes the stop element 26 from the accommodation tube 10 via the through orifice 253 of the receiving portion 25 so that the stop element 26 is pushed by a water pressure to matingly contact with the first inlet 131 of each first water gathering zone 13, thus avoiding water leakage. With reference to FIG. 6, when each push element 22 of the control bar 20 is further pushed to be stopped by the first shoulder 151 of the multiple first guide orifices 15, the first inlet 131 of each first water gathering zone 13 and the second inlet 141 of each second water gathering zone 14 are closed by the stop element 26 so as to stop the water, hence each nozzle element 31 of the first water gathering zone 13 and of the second water gathering zone 14 is closed so as to spray the water in a smaller area. Preferably, the stop element 26 is pushed by the water pressure to matingly contact with the first inlet 131 of each first water gathering zone
2018201187 07 Aug 2019 and the second inlet 141 of each second water gathering zone 14 so as to prevent the water flowing into each first water gathering zone 13 and each second water gathering zone 14. The receiving portion 25 of the control bar 20 accommodates the stop element 26, and the inflow chamber 24 communicates with the first inlet 131 of each first water gathering zone 13 and the second inlet 141 of each second water gathering zone 14 so as to control a number of the multiple nozzle elements 31 where the water sprays out.
[0020] Referring to FIGS. 7 and 8, in a second embodiment, the accommodation tube 10 does not include the multiple grooved partitions 12 of the first embodiment and includes multiple water gathering zones 13’, each of the multiple water gathering zones 13’ has an inlet 131’ defined on a bottom thereof and matching with the control bar 20, and each water gathering zone 13’ communicates with two or more than two nozzle elements 31, when the control bar 20 is pushed to the second peripheral side of the accommodation tube 10 until the inflow chamber 24 communicates with the inlet 131’ of each water gathering zone 13’, the water sprays out of each nozzle element 31 of each water outflow zone 11 from the water supply segment 101 of the accommodation tube 10, and the water flows into each water gathering zone 13’ so as to spray out of each nozzle element 31’ of each water gathering zone 13’ from the inlet 131’ via the inflow chamber 24 of the control bar 20, hence the water sprays out of each nozzle element 31’ in a large area. As shown in FIG. 9, when the each push element 22 of the control bar 20 is pushed to the second peripheral side of the accommodation tube 10, each water gathering zone 13’ is closed by the stop element 26 so that when the water is stopped flowing into each water gathering zone 13’, each nozzle element 31 of each water gathering zone 13’ is closed, thus spraying the water in a small area.
