Injection water-saving valve

Abstract

The invention discloses an injection water-saving valve, which is arranged in a water tank of a toilet stool and is used for feeding water into the water tank and pushing water current flowing into a bed pan from the water tank of the toilet stool. The injection water-saving valve comprises a water inlet pipe, a water inlet valve, an injection valve, a water inlet siphon preventing valve, an injection siphon preventing valve, an injection pipe and a water outlet, wherein the water inlet pipe is connected with an external water source; the water inlet valve and the injection valve are communicated with the water inlet pipe; the water inlet siphon preventing valve is communicated with the water inlet valve; the injection siphon preventing valve is communicated with the injection valve; the injection pipe is communicated with the injection siphon preventing valve; the water outlet is communicated with the water inlet siphon preventing valve and is used for draining water in the water tank; the injection valve is used for controlling the water injection to the middle or the bottom of the toilet stool or the bottom of an inlet of a sewage discharge pipeline; the water inlet valve is used for controlling water feeding to the water tank of the toilet stool and controlling the injection valve to be closed; when the water tank drains, the external water source is directly injected to the middle or the bottom of the toilet stool or the bottom of the inlet of the sewage discharge pipeline; and after the injection is carried out for 3-8 seconds, the injection valve is closed. According to the injection water-saving valve disclosed by the invention, water current drained from the water tank is pushed by the water pressure of the external water source to flush, so that the problem of high water consumption is solved; and the injection water-saving valve has the advantages of low water consumption, automatic control, simpleness and convenience in mounting and low cost.

Description

Technical field [0001] The invention relates to a jet water saving valve, in particular to a jet water saving valve installed in a toilet tank. Background technique [0002] Existing toilets generally only use 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 comes out of the water tank. The water pressure is very low, and more water is needed to flush the bedpan; some toilets are flushed directly with pressurized water such as tap water, but the water pressure requirements are higher, requiring a pressure of 300KPa or more, otherwise it will be difficult to flush and flush. There will be a loud noise sometimes. [0003] The existing water inlet valve that feeds water into the toilet tank generally only has an inlet pipe connected to an external water source and a water outlet for the w...

Problems solved by technology

[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

[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 water source and a water outlet that allows water to enter the water tank. A low water tank toilet can not reach the toilet seat due to the water discharged from the water tank. Thereby can not clean the upper wall in the closet, so there is also a kind of large replenishment water inlet valve specially used in the low water tank closet on the market, although this large replenishment water inlet valve has one more water outlet than the common water inlet valve, but the The outflowing water flows to the seat ring to clean the upper wall of the toilet
