Detailed Description

As shown in figure 1, the automatic liquid injector for cleaning liquid in the public toilet bowl or the urine bowl comprises a liquid storage barrel 1 for storing the cleaning liquid, wherein the liquid storage barrel 1 is connected with a water pressure liquid injection valve 4 through a liquid injection pipe 3.

As shown in fig. 2, the hydraulic pressure liquid injection valve 4 comprises a valve body 40 and a valve core, wherein the valve body 40 is provided with a liquid inlet nozzle 41 and a liquid outlet nozzle 42 which are communicated with a valve cavity 400, the liquid inlet nozzle 41 is connected with the liquid injection pipe 3, the liquid outlet nozzle 42 is connected with a liquid outlet pipe 8, and the other end of the liquid outlet pipe 8 is placed in a urine groove or a feces groove; the valve core comprises a valve core rod 43 and a valve core head 44, the valve core rod 43 is opposite to the through hole 410 of the liquid inlet nozzle 41, an O-shaped sealing ring 48 which is contacted with the inner wall of the valve cavity 400 is sleeved on the valve core head 44, a return spring 45 is sleeved on the valve core rod 43, one end of the return spring 45 acts on the valve core head 44, the other end acts on a valve core guide ring 46, the valve core guide ring 46 is movably sleeved on the valve core rod 43, and the inner wall of the valve body 40 is provided with a step which limits the upward movement of the valve core guide ring 46. The valve core guide ring 46 plays a role of supporting the spring 45 and a role of guiding the movement of the valve core rod 43; a valve cover 47 for connecting to the water pipe 6 is connected to the lower end of the valve body 40, and the valve cover 47 has a water inlet 470.

As shown in FIG. 1, the hydraulic filling valve 4 can be directly tightened on the water pipe by a pipe hoop 9 with a water valve seat 90. As shown in FIG. 3, the water valve seat 90 is connected to the special pipe hoop 9, when in installation, the water valve seat 90 is screwed into the water inlet 470 of the valve cover 47, and the pipe hoop 9 is tightened on the water pipe, and the hole is drilled on the water pipe and is communicated with the water inlet 470 of the valve cover 47 through the water valve seat 90; the hydraulic injection valve 4 may also be connected to a three-way pipe 5, as shown in fig. 1, the three-way pipe is connected to the water pipe 6 at one end and the flush valve 7 at the other end, and the three-way pipe is connected to the water inlet 470 of the valve cover 47 by screw threads. When the flush valve 7 is not flushed (when water in the water pipe does not flow), the water in the water pipe 6 supplies upward pressure to the valve core through the water inlet 470 on the valve cover 47, so that the valve core moves upward, the valve core rod 43 blocks the through hole 410 of the liquid inlet nozzle 41, so that cleaning liquid in the liquid storage barrel 1 cannot enter the valve cavity 400, and the O-shaped sealing ring 48 on the valve core head 44 can prevent water from entering the valve cavity 400; when the flushing valve 7 is flushed, water in the water pipe 6 is discharged, so that the water in the water pipe 6 does not give an upward pressure to the valve core, the valve core is put down and moved under the action of the return spring 45, the valve core rod 43 does not block the through hole 410 of the liquid inlet nozzle 41, so that cleaning liquid in the liquid storage barrel 1 enters the valve cavity 400, flows into a urine groove (or a feces groove) through the liquid outlet nozzle 42 and the liquid outlet pipe 8, is mixed with flushing water to flush the urine groove (or the feces groove), and keeps the urine groove (or the feces groove) clean.

In order to obtain a better sealing effect, a sealing washer 49 is arranged in the valve chamber 400, and the sealing washer 49 is positioned at one end of the through hole 410 of the liquid inlet nozzle 41. The valve core rod 43 acts on the sealing washer 49 to block the through hole 410 of the liquid inlet nozzle 41. Since the sealing washer 49 is made of rubber, the sealing effect is better.

Finally, the invention is characterized in that the liquid storage barrel 1 is provided with the regulating valve 2, and the liquid injection pipe 3 is connected with the regulating valve 2. The liquid outlet amount of the liquid storage barrel 1 can be adjusted by adjusting the adjusting valve 2.
