Description

Water stop valve and toilet

Technical field

The present invention relates to a valve and a toilet for use in a flush toilet, and more particularly to a water stop valve and a toilet. Background technique

With the development of urbanization, flush toilets have become the main health tools for people's daily lives. The impact of its water consumption and sewage pollution on the environment has aroused the attention of the whole society.

The water stop valve is placed on the water outlet of the toilet and is used to control the flushing device in conjunction with the control handle. The existing water stop valve generally includes a valve body matched with the water outlet of the stirrup and a connecting rod connecting the valve body to the control handle. After the control handle is pressed, the valve body is lifted, the water outlet is opened, and the toilet side is started. After flushing the basin, after releasing the control handle, the valve body will fall back to the water outlet with the water level falling, and the water outlet will be closed, so that the refilled water in the water tank will not flow out from the water outlet. However, since the water stop valve is always connected to the control handle through the connecting rod, as long as the control handle is pressed, the valve body is lifted and the water outlet is opened, so that if the user performs the flushing process, Inadvertently or accidentally pressing the control handle two or more times, the water outlet is opened during the filling of the water tank, and part of the water that has been filled into the water tank is passed through the water outlet to the side basin. Medium, resulting in unnecessary loss of water. Especially for children, who are curious or fun, they press the control handles several times in a row, which often occurs, causing waste of water.

In addition, the existing toilet generally dumps the water in the water tank from the upper part of the toilet bowl into the toilet bowl, and forms a top-down water pressure under the action of the atmospheric pressure of the air. Under the pressure, the dirt is removed from the toilet. The drain pipe at the lower end is discharged. The flushing toilet of this structure is difficult in process, the clay is expensive, the cost is high, and the water consumption is time-consuming, and the water consumption is about 7-12 liters per discharge. Moreover, this kind of flushing from top to bottom will produce relatively loud noise, especially at night, which will easily affect people's rest. How to reduce the noise during flushing is also one of the research directions of toilets.

The Chinese patent with the patent number ZL01220327. 0 provides a low-pressure type with better water-saving effect. Vacuum water saving device. The low-pressure vacuum water-saving device is provided with a chamber respectively communicating with an outlet and a sewage pipe at a lower portion of the side basin at a lower end of the water outlet of the water tank. When flushing, the user presses the control handle, and the water stop valve is lifted up. Water flows from the water outlet of the water tank into the chamber at the lower end of the water outlet, and most of the water flowing into the chamber flows into the side basin through the outlet at the lower part of the side basin. When the water in the water tank drops to a certain water level, the water stop valve falls. Opening the water outlet of the water tank. At this time, there is still some water in the chamber. When the water in the chamber flows out into the sewage pipeline, and the water in the toilet bowl has not flowed out, the chamber forms a vacuum to generate vacuum suction. The water in the side basin is returned to the chamber, and the dirt in the toilet bowl is flushed into the sewage pipe along with the water. The low-pressure vacuum water-saving device utilizes the combined force of the vacuum suction force and the water pressure in the toilet bowl, and the sewage discharge capability is greatly enhanced, so that less water (about 3.5 liters) can be used. Achieve a stable sewage effect.

The above-mentioned low-pressure vacuum water-saving device provides a toilet structure having a relatively good water-saving effect, but the toilet structure is provided with a water return device at the bottom of the side basin corresponding to the outlet position, and the water charged from the outlet touches A wave vortex is formed in the water returning device to flush the dirt in the side basin to improve the sewage discharge effect.
