Abstract

The invention relates to a toilet flushing device.

In order to not only wash the excrement completely, but also save water. The invention makes the water seal part of the urinal be a side U-shaped elbow with one end hinged with the floor drain and the other end sleeved with the sewer. When the toilet is flushed, the elbow swings downwards by external force, so that the inner cavity of the elbow is quickly filled with water flowing out of the toilet, a siphonage phenomenon is caused, and a mixture of excrement and water in the toilet is sucked out, so that the aim of completely flushing the toilet is fulfilled. The toilet flushing device has the advantages that: the urinal can be thoroughly flushed. But also can save water, because only 3-5 liters of water is used for flushing the urinal once; the well-known flushing device needs 13-15 liters of water for flushing the excrement once.

Description

The invention relates to a toilet flushing device, which is especially suitable for flushing stool.

Known flushing device, such as the siphon type flushing device introduced in the book "Water Supply, Drainage and Sanitary Equipment" published by China Building Industry Press in 1986. The water level of the water seal of the device is relatively high (generally 65-75mm), the area of the dry wall is small, and the feces are not easy to stick to the wall and do not stink. But it needs 15 liters of tap water per flush. The reason why it consumes a lot of water is that when flushing, the water level of the water seal is increased enough to completely fill the water seal elbow and the pipeline behind it, causing a siphon phenomenon. In the process of increasing the water level of the water seal, a large amount of tap water flowed away from the water seal elbow. The water seal water level height of another kind of falling water type flushing device introduced in this book is 50mm. Due to its large dry wall area, feces may stick to the wall and sometimes have a foul smell. The sanitation condition of this flushing device is relatively poor. But the water consumption is less, generally 12 liters. For a densely populated city, even if 12 liters of toilet water is used for each flush, the total water consumption is still considerable. For example, in a large city with a population of 1 million, 4.4 million tons of tap water are consumed just for flushing urinals a year.

The object of the present invention is to provide a toilet flushing device, which not only ensures good sanitary conditions, but also saves water.

The present invention can reach through following measures:

The flushing device of the present invention is composed of a urinal, a water tank, a control device, a pipeline, and an inverted U-shaped elbow. It is socketed with the sewer pipe; the top of the inverted U-shaped elbow is connected with the connecting rod in the control device; due to the lifting of the connecting rod, the inverted U-shaped elbow swings up and down around the axis of the hinged part of the urinal outlet.

Its control parts are made of water outlet valve, water inlet valve, float ball controlling water outlet valve and water inlet valve, handle, spring, rope connecting float ball and handle and connecting rod hinged with handle and inverted U-shaped elbow.

The top of the water tank of the device of the present invention can also be installed with a bathing device communicated with the inner cavity of the water tank.

Fig. 1 is a structural schematic diagram of the toilet flushing device of the present invention.

Fig. 2 is another structural schematic diagram of an inverted U-shaped elbow of the toilet flushing device of the present invention.

Fig. 3 is a side view of the inverted U-shaped elbow shown in Fig. 2 .

The present invention will be further described below by accompanying drawing:

In Figure 1, 1 is a urinal, 2 is a water tank, 3 is a control component, 4 is a pipeline, 5 is a sewer, 11 is a hose, 12 is an inverted U-shaped elbow, 13 is a retractable hose, and 21 is a face wash Pool, 31 is a water outlet valve, and 32 is a water inlet valve, and 33 is a float, and 34 is a handle, and 35 is a spring, and 36 is a rope, and 37 is a connecting rod.

The flushing device of the present invention works like this:

When flushing the toilet, push down the handle 34, and the rope 36 connected to the handle upwards pulls the float 33, and the float rod that passes the water outlet valve 31 upper end ring opens the water outlet valve, and a large amount of water flows into the urinal from the water tank. At the same time, the handle 34 pushes the U-shaped elbow to swing downwards through the connecting rod 37, so that the other end of the inverted U-shaped elbow swings downwards along the sewer 5 with the same radius of curvature, compressing the flexible hose 13. As the height of the elbow drops, the water flowing from the urinal quickly fills the inverted U-shaped elbow, causing a siphon phenomenon that sucks the mixture of feces and water in the urinal into the sewer. Remove the handle pressure, the handle resets under the action of the spring 35, and the inverted U-shaped elbow 12 is pulled back to its original position. At this time, the rope 36 releases the floating ball 33, and the floating ball swings downward to close the water outlet valve and open the water inlet valve. Tap water flows into the water tank, and when the water flows to a certain amount, the float floats up and closes the water inlet valve.

Used waste water such as washing one's hands and face is introduced into the water tank through the washbasin above the water tank 2. Like this, shut-off valve 6 can be closed artificially, so that what is full of in the water tank is all waste water. When the waste water level in the water tank rises to a certain height, the float ball opens the water outlet valve, and excess water is introduced into the sewer through the urinal. When the waste water level in the water tank drops to a certain position, the float ball closes the water outlet valve again.

The hinged form of the inverted U-shaped pipe 12 and the pool water outlet 15 can also adopt the structure shown in FIG. 2 , that is, one end of the inverted U-shaped elbow 12 rotates around the axis of the pool water outlet 15 . The connection between the inverted U-shaped elbow 12 and the sewer 5 is shown in FIG. 3 .

Compared with the known technology, the flushing device of the present invention has the following advantages:

Because the water seal elbow of the known flushing device is fixed, it is necessary to make the water level of the urinal rise to a certain height after a period of time when flushing, so that the fixed elbow and its pipeline behind the water seal are all filled with water. The siphon phenomenon flushes the urinal. Of course, this requires 13-15 liters of water; and the water seal of the toilet flushing device of the present invention is replaced by an inverted U-shaped elbow, and its water level can be artificially changed, and the height of the inverted U-shaped elbow can be lowered when flushing. It quickly causes a siphon phenomenon, and its water consumption is only 3 liters.

The inverted U-shaped tube of the water seal of the toilet flushing device of the present invention is adjustable, and the inverted U-shaped elbow can be raised to make the water level in the urinal higher, such as 200 mm; while the water seal of the known siphon flushing device has the highest water level It is 75mm, so the flushing device of the present invention will never make the feces stick to the urinal, let alone overflow the foul smell.

If the invention flushing device utilizes waste water to flush the urinal, tap water can be further saved.
