When a pipeline in a terminal product is blocked, the conventional operation method is to directly disassemble the terminal product and then dredge the terminal product, so that the efficiency is extremely low, and the operation is complicated.
In the embodiment, a pressure pump 14, a raindrop sensor 16 and a single chip microcomputer are arranged, wherein the raindrop sensor 16 is a tablet raindrop sensor, the principle is that vibration of water drops falling on the raindrop sensor is converted into an electric signal, a first water outlet is formed in a first water outlet barrel 7, a water inlet end of the pressure pump 14 is connected with the first water outlet through a second flow pipeline 15, when water flow impacts a first closing plate 4 to be separated from a first water outlet pipe 6, the water flow falls on the raindrop sensor 16 from the periphery of the first closing plate 4, the raindrop sensor 16 sends a signal to the pressure pump 14, the pressure pump 14 is started, the water flow in the first water outlet barrel 7 is divided into two paths, one path enters a second water outlet barrel 11, the other path enters the pressure pump 14 for pressurization and acceleration, then is discharged into a pipeline of a terminal product through a third flow pipeline 17, the water flow speed discharged from the third flow pipeline 17 is high, the impact force is strong, larger impact force is applied to blockage in a pipeline of a terminal product, and the blockage can be directly dredged for small blockage, so that small blockage of the pipeline of the terminal product can be solved, the terminal product does not need to be disassembled for dredging, meanwhile, because water exists in the pipeline all the time, water in the third circulation pipeline 17 is discharged to force water in the original pipeline to be discharged from the first through hole in a reverse flow mode, the flow of the whole water circulation can be kept unchanged, the water can not enter the water inlet pipe 2 from the outside due to the diversion of the pressure pump 14, once the small blockage is dredged, the water in the water outlet pipe 3 recovers the normal pressure, at the moment, due to the elastic restoring force of the first spring 5 and the second spring 9, the first closing plate 4 can return to the first water outlet pipe 6, the second closing plate 12 can return to the second water outlet pipe 10, and the gravity of the water flow is not enough to completely overcome the elastic restoring force of the first spring 5, therefore, the first closing plate 4 and the second closing plate 12 can block the first water outlet pipe 6 and the second water outlet pipe 10, water flow cannot be discharged from the space between the first water outlet pipe 6 and the second water outlet pipe 10 in a large amount, only weak leakage can occur, normal operation of the device is not affected, meanwhile, the raindrop sensor 16 is positioned on the side edge of the first water outlet pipe 6, and the raindrop sensor 16 is positioned above the water outlet hole and the first water outlet hole, so when water leaks from the space between the first closing plate 4 and the first water outlet pipe 6, the water cannot fall onto the raindrop sensor 16 or falls a little, the water is not enough to reach a starting value of the single chip microcomputer controlled pressure pump 4, the pressure pump 4 stops working, the pump body 1 works normally, meanwhile, an alarm can be arranged, the single chip microcomputer controlled pressure pump 4 also controls the alarm to alarm after being started, and thus workers can be informed that a pipeline of a terminal product is blocked, in this way, after a stop, the worker can re-stick the first closing plate 4 and the second closing plate 12 to prevent the next blockage of the pipeline of the end product.
The water-saving water dispenser further comprises a third water outlet pipe 19, a third sealing plate 20, a third water outlet barrel 21, a third spring 22, a fixing plate 23 and a third water inlet pipe 24, wherein the water outlet pipe 3 is provided with an electromagnetic valve 18, the electromagnetic valve 18 is positioned on the right side of the first through hole, the water outlet pipe 3 is provided with a third through hole, the third through hole is positioned on the right side of the electromagnetic valve 18, the bottom end of the third water outlet barrel 21 is sealed, the top end of the third water outlet barrel 21 is connected with the inner top wall of the containing box 8, the inner diameter of the third water outlet barrel 21 is larger than that of the third water outlet pipe 19, the top end of the third water outlet pipe 19 is connected with the side wall of the third through hole, the bottom end of the third water outlet pipe 19 penetrates through the top wall of the containing box 8 to be communicated with the third water outlet barrel 21, the third sealing plate 20 is positioned in the third water outlet pipe 19, the side wall of the third sealing plate 20 is contacted with the inner wall of the third water outlet pipe 19, and the third water outlet pipe 19 is sealed by waterproof glue,
the inner wall of the third water outlet barrel 21 is connected with a fixing plate 23 through a connecting rod, and two ends of the third spring 22 are respectively connected with the fixing plate 23 and the bottom wall of the third closing plate 20;
the third water outlet barrel 21 is provided with a second water outlet hole, the second water outlet barrel 11 is provided with a second water inlet hole, and two ends of the third water inlet pipe 24 are respectively connected with the second water outlet hole and the second water inlet hole.
In the process of self-dredging, because the pipeline of the terminal product is filled with water, when water flow sprayed from the third circulating pipeline 17 enters the pipeline of the terminal product, the impact force acting on a blocked position is greatly weakened after the water sprayed from the third circulating pipeline 17 is mixed with the water in the pipeline, so that the blocked position is slightly serious and the terminal product cannot be dredged, in the technical scheme, the electromagnetic valve 18 is arranged on the water outlet pipe 3, the electromagnetic valve 18 is positioned at the right side of the first through hole, when the self-dredging cannot be dredged, the pipeline of the terminal product can be disconnected with the water outlet pipe 3, the water in the pipeline of the terminal product is discharged, then the pipeline of the terminal product is connected with the water outlet pipe 3, the electromagnetic valve 18 is closed, the electromagnetic valve 18 prevents the water in the water outlet pipe 3 from directly entering the pipeline of the terminal product, at the moment, the pump body 1 works, the water flow passes through the water outlet pipe 3 and then enters the first water outlet barrel 7 from the first water outlet pipe 6, one part directly enters the second water outlet barrel 11 for circulation, the other part enters the booster pump 14 from the first water outlet barrel 7 and is sprayed out through the third flow pipeline 17, because the pipeline of the end product is not filled with water, the water flow sprayed by the third circulating pipeline 17 directly impacts the blocked part, the impact acting force is stronger, therefore, the dredging can be carried out aiming at the serious blockage condition, if the impact force is still unable to dredge, the input water flow forms high pressure, then the third closing plate 20 is pressed, and then enters the water inlet pipe 2 through the third water outlet barrel 21 and the third water inlet pipe 24 for circulation, also can prevent like this that the too big damage that causes of water pressure in the pipeline of terminal product, so can use pump body 1 to further dredge to pipeline jam in the terminal product, if unable mediation, carry out the start maintenance of terminal product again, so can dredge to the general condition of most jam degree.
