Description

Water-saving toilet

Technical Field

The invention relates to a toilet bowl, in particular to a water-saving toilet bowl.

Background

At present, with the continuous improvement of living standard of people, various toilet bowls are produced, and simultaneously, the requirements of people on the toilet bowls are more and more strict. For example, the appearance, material and performance of the toilet are becoming the focus of attention. Particularly, in the current society with shortage of water resources, the water consumption of the toilet bowl becomes the focus of attention of people. However, many toilets in the prior art often have water consumption far less than that of people. The traditional toilet bowl is mostly composed of a toilet bowl body and a water tank, wherein the water tank is mainly used for storing water, so that after people use the toilet bowl, a valve of the water tank can be opened, and the stored water in the water tank is discharged to the toilet bowl body by means of the gravity of the stored water in the water tank to flush dirt. Obviously, the flushing effect of the sewage in the toilet bowl is realized by depending on the water storage amount in the water tank. However, the dirt in the toilet body is difficult to be thoroughly washed out at one time only by the gravity of the water stored in the water tank, so that people often have to open the valve of the water tank for multiple times after using the toilet to thoroughly wash the dirt in the toilet body, and a large amount of water resources are wasted invisibly. The pressure device is additionally arranged in the water tank and used for increasing the pressure of the stored water in the water tank so as to ensure that the downward flushing force of the stored water in the water tank is larger. Although certain water resource can be saved from the toilet, the structure of the pressure device is complex and the installation is inconvenient, so that the toilet has certain limitation on production and application. The other toilet bowl in the prior art does not need a water tank for storing water, but directly utilizes a delay switch to be matched with a water pipe for flushing the toilet bowl body. However, the delay switch of the toilet bowl is in a process of gradually returning after being pressed, and in the process, part of water flow flows into the toilet bowl and is brought into the sewer pipe, so that the phenomenon of water resource waste can be generated in the flushing process of the toilet bowl.

The specific working process of the water-saving toilet of the invention is shown in fig. 3 to 6: when the pedal 38 is not stepped on by foot, the peripheral edge of the tray 12 covers the through hole 111 of the toilet pan 11, and a certain amount of water 4 is reserved between the pan surface of the tray 12 and the through hole 111 of the toilet pan 11 for water sealing. At this time, the water inlet of the water inlet valve 2 is not opened; when the pedal 38 is stepped on by a foot, the operating lever 36 drives the third rotating shaft 35 and the first rod 33 to rotate at the same time, and the L-shaped rod 39 linked with the third rotating shaft 35 slides along the sliding slot 123 at the bottom of the tray 12 along with the rotation of the third rotating shaft 35 and pushes the tray 12 to turn downwards; the second tension spring 34 linked with the first rod 33 is stretched along the rotation direction of the first rod 33, so as to drive the second rod 32 connected with the first rod 33 to pull the water inlet valve 2 to open. When the tray 12 is in an inclined and overturned state, the dirt in the tray 12 will sequentially fall down, and simultaneously, with the opening of the water inlet valve 2, the water flows out of the first flushing outlet 115, the second flushing outlet 113 and the third flushing outlet 116, and the water flows out of the first flushing outlet 115 and the second flushing outlet 113 respectively perform flushing action on the periphery of the toilet bowl 11 and the upper surface of the tray 12. Since the tray 12 is tilted during the process of flushing, the dirt in the tray 12 tends to fall down under the influence of gravity, so that the dirt can be easily poured out of the tray 12, and the tray 12 can be flushed clean with a small amount of water. The water from the third flushing outlet 116 comes from the small water tank 13, when the water inlet valve 2 is opened, the water enters the small water tank 13, and because the small water tank 13 is connected to the third flushing outlet 116 through a thin pipe, when the water inlet valve 2 is closed, the water in the small water tank 13 does not flow out. When the foot leaves the pedal 38, the third rotating shaft 35 is reset under the action of the torsion spring, and under the reset action of the second tension spring 34, the toggle switch of the water inlet valve 2 is closed, the tray 12 is also re-supported at the through hole 111 of the toilet pan 11 under the driving of the first link mechanism, and the fine water flow flowing out of the third flushing outlet 116 continuously flows into the toilet pan 11 and then enters the tray 12, so that the tray 12 keeps a certain amount of water, and a water sealing effect on the sewage draining outlet is formed.

The water-saving toilet of the invention is characterized in that the opening 111 of the toilet pan 11 is provided with the reversible tray 12, the rear wall of the extending wall 114 of the toilet pan opening 111 is provided with at least one second flushing outlet 113, and the operating mechanism 3 which is linked with the tray 12 and the water inlet valve 2 to control the overturning of the tray 12 and the action of the water inlet valve 2 is arranged, and the operating mechanism 3 is composed of an operating rod 36, a third rotating shaft 35, a torsion spring, a first connecting rod mechanism and a second connecting rod mechanism, so that the tray 12 of the toilet can carry out inclined pollution discharge under the driving of the operating rod 36, the water inlet valve 2 of the toilet can carry out opening action when the tray 12 is inclined and overturned, so that water flow can respectively flush out from the first flushing outlet 115 and the second flushing outlet 113 on the toilet pan 11 and respectively wash out the periphery of the tray 11 and the upper surface of the tray 12, thereby enabling the dirt on the tray 12 to be quickly flushed, And thoroughly washing the mixture. Because the sewage on the toilet bowl is flushed more thoroughly and quickly by the dumping action of the tray 12 and the matched flushing action of the water flow flushed from the first flushing outlet 115 and the second flushing outlet 113, and a large amount of water resources can be saved; experiments prove that the bedpan and the tray thereof can be flushed clean only by using about 0.6 liter of water. In addition, because the toilet body 1 of the invention is also provided with the small water tank 13 for placing the disinfectant, and the small water tank 13 is communicated with the third flushing outlet 116 of the toilet body 1 through the thin water pipe, the dissolution speed of the disinfectant pills placed in the small water tank 13 is slower, so that the disinfectant pills placed in the small water tank 13 can be used for a longer time.

In conclusion, the water-saving toilet disclosed by the invention has the characteristics of simple structure, convenience in operation, remarkable water-saving function, thorough flushing and the like.

The above embodiments are only used to further illustrate the water saving toilet of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention fall within the protection scope of the technical solution of the present invention.
