implementation plan

Referring to Fig. 1-Fig. 3, this implementation mainly consists of water inlet valve 1, floating bucket 2, floating bucket basin 3, water inlet replenishment pipe 4, 3 liters to 6 liters of double-block drain valve 5 installed in the drop type flush water tank. , Floating ball lever type pressure flushing control switch 8, water receiving basin 6, floating ball 7, sealing rubber sheet 9, switch opening connecting hose 10, back pressure drainage control valve 11, back pressure valve drain outlet connected to the auxiliary flushing pipe 12. The jet flushing port 13 before the sewage outlet, the tap water inlet connection tee 14, the tap water inlet pipe switch 15, the switch port 16, and the drainage hole 17 constitute. The working process is like this. First, the tap water enters the connection tee 14 from the switch 15, and a part of the water enters the water inlet valve 1 of the drop-type flushing water tank. Since the water tank has no water, the floating bucket 2 descends and the water inlet valve 1 opens, and the water enters the water tank. Water replenishment pipe 4 has water to flow out simultaneously. The other part of the water enters the back pressure drain control valve 11. As the float 7 of the float lever pressure flushing control switch 8 descends, it drives the sealing rubber sheet 9 to rise, the switch port 16 opens, and the water enters the drain port of the back pressure valve and the auxiliary valve. The flushing pipe connection 12 is ejected through the jet flushing port 13 in front of the sewage outlet. When the water flowing out of the water supply pipe 4 fills the water receiving basin 6, the gravity drives the lever to move downward, and the sealing rubber sheet 9 descends to press the switch port 16. The floating ball 7 rises upward, the back pressure drainage control valve 11 is closed, the spray flushing port 13 in front of the sewage outlet stops spraying water, and the water intake continues until the water rises to float the floating barrel 2 of the water inlet valve 1, and the water inlet valve 1 Closing the water inlet is completed, and the water in the water inlet replenishment pipe 4 stops flowing out. The water of water receiving basin 6 flows out by the drain hole 17 of basin bottom, and the closing work of back pressure type drainage control valve 11 is replaced by the floating ball 7 that water floats, and the whole water inlet process is finished, and waits for next draining flushing process.

When flushing is needed, just press one of the switches of the 3-liter to 6-liter dual-block drain valve 5, the switch is opened, the water is discharged from the toilet pipe, the water level of the water tank drops, and the float 7 of the float lever type pressure flushing control switch 8 simultaneously Descending, driving the sealing rubber sheet 9 and the water receiving basin 6 to rise, the back pressure drainage control valve 11 is opened, and the high-pressure water flow from the tap water belt passes through the drain port of the back pressure valve and is connected to the flushing aid pipe 12 by the jet flushing port in front of the sewage outlet 13 sprays out, and the water flow flowing out of the same toilet pipeline discharges the dirt out of the drainpipe rapidly. When the water level of the water tank dropped to the height of setting, 3 liters～6 liters of double gear drain valves 5 were closed. Simultaneously because the time-delay effect played by the smaller drainage holes of the floating bucket basin 3, the floating bucket 2 is slowly descended. The water flows out, and when the water receiving basin 6 is filled, the gravity drives the sealing rubber sheet 9 to descend to seal the switch opening 16, the float 7 rises, the back pressure drainage control valve 11 is closed, and the jet flushing port 13 before the sewage outlet stops spraying water. Water intake continues until the floating bucket 2 of the water inlet valve 1 floats, and stops when the water inlet valve 1 is closed, and the water inlet replenishment pipe 4 stops flowing water simultaneously. The water of water receiving basin 6 is discharged by drain hole 17, and work is replaced by floating ball 7 that floats. The process of draining and entering water is completed, waiting for the next process of draining and flushing.

The switch of the pressure flushing device of the utility model is mainly implemented by a floating ball lever type pressure flushing control switch 8, a floating ball 7 connected to the lever, the other end is the water receiving basin 6 and the drainage hole 17 of the water receiving basin is the water inlet above it. The water supply pipe 4 also has a sealing rubber sheet 9 in the middle, a switch opening 16 aligned with the lower side, a hose 10 connected to the outside of the water tank, and is connected with the switch opening of the back pressure drainage control valve 11, and the back pressure drainage control valve 11 The inside has the rubber sheet 18 that is fixed on the valve body and has aperture in the middle, and it aligns with the water inlet 19 on the lower side, and the other side is a discharge port 20 to form. The working process is like this, when the water receiving basin 6 has no water and the floating ball 7 has no buoyancy, the lever will lower the end of the floating ball under the gravity of the floating ball 7, driving the sealing rubber sheet 9 and the water receiving basin 6 at the other end to rise , switch opening 16 is opened, and tap water enters by water inlet 19, pushes away the rubber sheet 18 that has aperture in the middle to spray from the spray flushing port 13 before drain outlet 20 to sewage outlet. When the water receiving basin 6 is filled with water or the water floats the float 7, the lever drives the sealing rubber sheet 9 to descend to seal the switch opening 16. At this time, the tap water passes through the small hole in the middle of the rubber sheet 18 with small holes in the middle to enlarge the middle. The pressure above the rubber sheet 18 with small holes, because the area above the rubber sheet 18 with small holes in the middle is larger than the area of the water inlet 19, so the pressure is greater, and in turn, the rubber sheet 18 with small holes in the middle is lifted up. Live in water inlet 19, realize closing back pressure type drainage control valve.
