In order to ensure that the transfer passage 51 is always communicated with the hydraulic chamber 22, the side portion of the upper annular outer edge 27 of the present embodiment is provided with a horizontal communication hole 52 extending therethrough in the horizontal direction.
The working principle and the technical effect of the scheme are as follows:
initial state of the mechanism (fig. 4): the lower side surface of the upper annular outer edge 27 is in a contact state with the upper surface of the upper piston wall 1.1, each liquid transfer hole 28 is blocked by the inner wall of the lower slide hole 4, and the lower end of the ejector rod 31 is lower than the lower surface of the spring retaining disc 9; at the moment, the upper surface of the upper annular outer edge 27 is just pressed upwards against the lower surface of the disc-shaped top wall 87, and due to the existence of the horizontal communication hole 52, the liquid transfer channel 51 is still communicated with the hydraulic pressure chamber 22 in the state, and the hydraulic pressure of the liquid transfer channel 51 is always consistent with that of the hydraulic pressure chamber 22;
the working process is as follows:
the water supply main pipe 26 starts to continuously supply water with water pressure as P, the spray head 18 decompressed by the spray head decompression valve 25 upwards sprays jet with the water pressure as P, then the water jet upwards sprayed by the spray head 18 impacts the conical surface 38 on the jet refraction cone 12 to be guided and refracted to form water jet which is divergently sprayed to the periphery, all the divergently sprayed jet is obliquely upwards sprayed in the form of oblique jet 37 along the slope of the conical surface 38 of the jet refraction cone 12, irrigation on the peripheral vegetation is further realized, and the upward spraying state of the spray head 18 is always kept in the subsequent process;
meanwhile, the branch water pipe 20 transmits the water pressure which is not reduced to the water pressure chamber 22, since it is defined that F2 is greater than F1, the oscillation piston 1 and the movable cylinder 24 will rapidly accelerate to move downwards under the action of the high water pressure in the water pressure chamber 22 until the lower end of the ejector rod 31 just pushes against the upper surface of the disc-shaped bottom wall 33, the downward movement of the movable cylinder 24 is rigidly blocked, and the oscillation piston 1 and the spring plate 9 continue to move downwards under the action of the high water pressure in the water pressure chamber 22, so that the relative movement of the movable cylinder 24 and the oscillation piston 1 in the vertical direction occurs until the spring plate 9 also drops to contact the upper surface of the disc-shaped bottom wall 33 (as shown in fig. 5), each liquid transfer hole 28 just communicates with the disc cavity 2, and simultaneously the lower surface of the lower piston wall 1.2 pushes against the button 30, the electromagnetic valve controller 19 will immediately energize the normally open electromagnetic valve 21 for a period of time (set to 3 seconds in this embodiment) after the button 30 is pressed, then waits for the button 30 to be pressed again; in the descending process of the oscillating piston 1, the jet refraction cone 12 can be accelerated and displaced for a certain distance, and then the process of one-time downward oscillation of the jet refraction cone 12 is realized;
the electromagnetic valve 21 is blocked within 3 seconds after the normally open electromagnetic valve 21 is electrified, the water pressure of the branch water pipe 20 cannot be transmitted to the water pressure cavity 22, meanwhile, each liquid transfer hole 28 is just completely communicated with the disc cavity 2, so that the water pressure cavity 22 at the moment is sequentially communicated with the liquid transfer channel 51, each liquid transfer hole 28, the disc cavity 2, the communication channel 19 and each liquid guide channel 15, and is finally communicated with the outside through the plurality of guide outlets 16, so that the water pressure cavity 22 loses the downward acting force on the oscillation piston 1, because the upward acting force F1 of the spray head 18 on the jet refraction cone 12 still exists, at the moment, the jet refraction cone 12 performs upward accelerated motion under the action of F1, the upward accelerated motion of the jet refraction cone 12 can enable the oscillation piston 1 to perform upward accelerated displacement (as shown in figure 6), and the water originally filled in the water pressure cavity 22 can be extruded in a divergent manner in a horizontal jet 36 through the plurality of the guide outlets 16 in the upward displacement of the oscillation piston 1, at least part of the horizontal jet 36 and part of the oblique jet 37 are subjected to intersection collision, as shown in fig. 9, splashed water after intersection collision is splashed in a position closer to the spray head 18, so that the traditional vegetation irrigation mode that only far spray can be avoided and the position close to the spray head 18 is ignored, the oscillating piston 1 is ensured to move upwards to the position of the initial state within 3 seconds by controlling the size of F1, and then the process of one-time upwards oscillation of the jet refraction cone 12 is realized; the disc-shaped top wall 87 pushes the movable cylinder 24 downwards, so that each liquid transferring hole 28 is blocked by the inner wall of the lower sliding hole 4, and the liquid transferring holes completely return to the initial state of the mechanism and then enter the next oscillation period after waiting for 3 seconds;
according to the above rule, the jet refraction cone 12 will oscillate up and down periodically, when the jet refraction cone 12 oscillates upwards, it is equivalent to that the jet ejected by the nozzle 18 is ejected to the jet refraction cone 12 more slowly, when the jet refraction cone 12 oscillates downwards, it is equivalent to that the jet ejected by the nozzle 18 is ejected to the jet refraction cone 12 more heavily; therefore, the initial jetting speed of the water jet which is formed by diffusing and jetting around after the drainage refraction of the conical surface 38 on the jet refraction cone 12 is changed all the time, and the final sprinkling of the water jet is wider, so that the effect of increasing the effective irrigation area of a single spray head is realized.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
