Self-closed water-saving device, method and toilet stool

Abstract

The invention discloses a self-closed water-saving device, a method and a toilet stool, which meet the purposes of flushing dirt by using a high-pressure water source or a low-pressure water source and saving water. A main valve and a secondary valve are buoy control valves; the water inlet part of the secondary valve is communicated with the water outlet part of the main valve; the upper edge of a buoy tank of the secondary valve is higher than that of a buoy tank of the main valve; the upper part of the buoy tank of the main valve is communicated with the buoy tank of the secondary valve through a communicator; the openness of a one-way valve of the buoy tank of the secondary valve is lower than that of a one-way valve of the buoy tank of the main valve; a link mechanism of the secondary valve opens a hole of a valve cover of the secondary valve along with flotation of a buoy, and a link mechanism of the main valve closes the hole of the valve cover of the secondary valve along with flotation of the buoy; the water outlet part of the secondary valve is communicated with an injection thrusting port; the secondary valve is also provided with a secondary valve water outlet tank higher than the valve port; the secondary valve water outlet tank is communicated with the water outlet for discharging water to a water tank; and a valve core of the secondary valve plugs the secondary valve water outlet tank and one part and the other part of a secondary valve water outlet part at the same time.

Description

technical field [0001] The invention relates to a self-closing water-saving device for feeding water into a water tank of a toilet and a toilet equipped with the device. 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, requiring a relatively large amount of water 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 There is a loud noise when flushing. [0003] The existing buoy self-closing water inlet device that feeds water into the toilet tank generally only has a water inlet ...

[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, requiring a relatively large amount of water 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 Loud noise when flushing

[0003] The existing buoy self-closing water inlet device that feeds water into the toilet tank generally only has a water inlet connected to an external water source and a water outlet that feeds water into the water tank. It cannot reach the toilet seat and thus cannot clean the upper wall of the toilet, so there is also a float self-closing water inlet device specially used for low tank toilets on the market. Although this device has one more outlet than the ordinary float self-close water inlet device The water outlet, but the water flowing out of this outlet flows to the seat ring to clean the upper wall of the toilet
