Water-saving device

Abstract

The invention provides a water-saving device which is installed in a water tank of a water closet, is used for feeding water into the water tank, and is used for pushing water flowing from the water tank of the water closet into a bedpan. The water-saving device comprises a water inlet pipe, a main valve, an auxiliary valve, an injection pipe and a water outlet, wherein the water inlet pipe is connected with an external water source; the main valve is communicated with the water inlet pipe; the auxiliary valve is adjacent to the main valve; the injection pipe is communicated with the auxiliary valve; the water outlet is used for discharging water into the water tank; the auxiliary valve controls water to be sprayed to the middle or bottom of the bedpan or the bottom of an inlet of a blow-off line; and the main valve controls water to be fed into the water tank of the water closet, and controls the auxiliary valve to be opened. In the invention, the water discharged from the water tank is pushed by the water pressure of the external water source for flushing, thereby effectively solving the problem of large water consumption. The water-saving device has the advantages of little water consumption and low cost and is simple and convenient to install.

Description

technical field [0001] The invention relates to a water-saving device, in particular to a 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.

[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
