[0002] Existing closets generally only rely on the water discharged from the water tank to flush the bedpan. Although there are spray holes at the bottom of the bedpan, the water sprayed from the spray holes also comes from the water tank. Due to the limited height of the water tank, the water coming out of the water tank The water pressure is very low, and more water is needed to flush the bedpan; some toilets are completely flushed with pressure water such as tap water, but the water pressure is relatively high, requiring a pressure of more than 300KPa, otherwise it is difficult to flush clean, and flushing loud noise

specific Embodiment approach 2

[0151] In specific embodiment one, the water outlet 12 is above the jet valve float tank B, the purpose of this design is to easily guide the water flowing out from the water outlet 12 to the jet valve float tank B so that the water in the jet valve float tank B When it is full, the jet valve float mechanism 30 floats up to close the jet valve. In fact, there are many ways to achieve this goal. The water outlet 12 does not have to be above the jet valve float tank B. In the second embodiment, the water outlet 12 Connect with the jet valve float tank B with a connecting pipe, so that all or part of the water flowing out from the water outlet 12 flows to the jet valve float tank B and then flows into the water tank, so that the purpose as in the first embodiment is achieved, and the rest All the components are exactly the same as those in the first embodiment, and the working principle and steps are also the same, which will not be repeated here.

specific Embodiment approach 3

[0152] In the first embodiment, a water inlet anti-siphon valve and a jet anti-siphon valve are set. In fact, the existence of the anti-siphon valve has no effect on the opening and closing of the water inlet valve and the jet valve. During water, running water pipeline can produce negative pressure, and anti-siphon valve core 43 moves down and covers water inlet anti-siphon valve inlet chamber 4 and jet anti-siphon valve inlet chamber 8, and air can be communicated up and down from main valve cover 16 again. Enter in the valve in the siphon ventilation groove 19, the negative pressure that running water pipe produces can not play a role to jet pipe 15, water outlet 12, replenishing water pipe 41 like this, guaranteed like this the water in the water tank and bedpan can not be sucked back; If Regardless of the above-mentioned factors, the anti-siphon valve may not be needed. On the basis of the first embodiment, as long as the anti-siphon valve core 43 is removed and the anti-s...

Abstract

The invention discloses an injection water-saving device which is arranged in a toilet stool water tank and used for supplying water for the water tank and pushing the water flow flowing from the toilet stool water tank into a lavatory pan. The injection water-saving device comprises a water inlet pipe connected with an external water source, an inlet valve and an injection valve both of which are communicated with the water inlet pipe, an injection pipe and an water outlet for draining water into the water tank; and the injection valve controls water injection to the middle part or bottom of the toilet stool or the bottom of the inlet of a sewerage pipeline, the inlet valve controls the water supply to the toilet stool water tank and controls the close of the injection valve, when the water tank drains, the external water source directly injects water at the middle part or bottom of the toilet stool or the bottom of the inlet of the sewerage pipeline, and after water is injected for 3-8 seconds, the injection valve is closed. In the injection water-saving device, the water pressure of the external water source pushes the water flow drained from the water tank to flush the toilet stool, in such a way, the problem of high water consumption is solved, and the toilet stool consumes less water, can be automatically controlled and simply and conveniently installed, and has low cost.

Description

technical field [0001] The invention relates to a spray water-saving device, in particular to a spray water-saving device installed in a toilet water tank. Background technique [0002] Existing closets generally only rely on the water discharged from the water tank to flush the bedpan. Although there are spray holes at the bottom of the bedpan, the water sprayed from the spray holes also comes from the water tank. Due to the limited height of the water tank, the water coming out of the water tank The water pressure is very low, and more water is needed to flush the bedpan; some toilets are completely flushed with pressure water such as tap water, but the water pressure is relatively high, requiring a pressure of more than 300KPa, otherwise it is difficult to flush clean, and flushing Sometimes there will be a loud noise. [0003] Existing water inlet valves that feed water into the water tank of the toilet generally only have a water inlet pipe connected to an external wat...
