Description

A water-saving and environment-friendly water tank

technical field

The invention relates to a water-saving and environment-friendly water tank.

Background technique

Traditional flush toilets are flushed with clean tap water, which is a waste of water resources. The sewage in our life is generally discharged directly, and a large part of it can be reused. If the reusable water can be conveniently used to flush the toilet, a lot of water resources can be saved, and it is also very economical. .

Contents of the invention

The object of the present invention is to provide a water-saving and environment-friendly water tank, so as to realize the use of reusable domestic sewage to flush the toilet.

To achieve the above object, the present invention adopts the following technical solutions:

A water-saving and environment-friendly water tank comprises two layers of water tanks, the bottom of the upper water tank has a vertical pipe body 1, the upper port of the pipe body 1 has a valve 1, and the side has a valve 2, and the upper water tank is connected with a running water pipe. There is a vertical pipe body 2 in the lower water tank, the upper port of the pipe body 2 is connected with the pipe body 1, and a valve 3 is arranged at the interface, and the lower end passes through the bottom of the lower water tank to connect with the toilet, and the upper end of the pipe body 2 is located at the bottom of the lower water tank A valve 4 is provided. The upper part of the lower water tank is connected to the water pipe 1, the other end of the water pipe 1 is connected to the water pipe 2 and the water pipe 3 through a reversing valve, the other end of the water pipe 3 is connected to the pool, the water pipe 1 and the water pipe 2 are also connected through the water pipe 4, and the water pipe 4 is connected to the water pipe 1. The position of the connection is higher than the connection between the water pipe 4 and the water pipe 2 to ensure that water will not flow from the water pipe 2 into the water pipe 1 .

Valve 1 and valve 3 are connected through a connecting rod, and valve 3 is controlled by a buoyancy device. When the water level of the lower water tank is higher than position 1, valve 3 remains closed and valve 1 remains open; when the water level is lower than position 2, valve 3 remains open State, valve 1 remains closed, when the water level is between position 2 and position 1, valve 1 and valve 3 are open at the same time, position 2 is lower than position 1.

Valve 2 and valve 4 are controlled by two switches respectively.

A water level display tube can be set outside the lower water tank to display the water level in the water tank. The water level display tube can be fully enclosed or open at the top. Odors that may be produced by reused water are filtered out.

The working principle of the water-saving and environment-friendly water tank of the present invention is: the water used in daily life enters the water pipe 1 through the pool, and is diverted through the reversing valve according to its usable value, and the water that can be reused enters the water pipe 4, and the water that cannot be reused Enter water pipe 2 and drain directly. The water that enters water pipe 4 can enter lower floor water tank. After the water of lower floor water tank was full, even the water that entered water pipe 4 also can be drained by water pipe 3 again.

Clean tap water enters the upper water tank through the tap water pipe.

When the upper and lower water tanks are full of water, when in use, open the valve 4 through the switch, and the water in the lower water tank will flow out through the pipe body 2 for flushing. When the water level drops to a certain position, the buoyancy device will work, and the valve 3 will be opened. , part of the clean tap water in the upper water tank (the water level above valve 1) will enter the pipe body 1, and then enter the pipe body 2, so that after flushing, what remains in the toilet is still clean tap water, not reused and There is definitely dirty water.

When the water level in the lower water tank was not enough, the valve 2 could be opened directly by a switch, and the water in the upper water tank could be used to flush the toilet.

The water-saving and environment-friendly water tank provided by the invention realizes selective secondary utilization of domestic waste water, saves water resources, and is economical and practical.

Detailed ways

As shown in Figure 1, a water-saving and environment-friendly water tank includes two upper and lower water tanks, the upper water tank (10) has a vertical pipe body 1 (7) at the bottom, and the upper port of the pipe body 1 (7) has a valve 1 (8), Valve 2 (9) is arranged on the side, and the upper water tank (10) links to each other with running water pipe (6). There is a vertical pipe body 2 (12) in the lower floor water tank (15), the upper port of the pipe body 2 (12) is connected with the pipe body 1 (7), the interface is provided with a valve 3 (11), and the lower end passes through the lower floor water tank ( 15) The bottom is connected with the toilet, and the valve 4 (13) is arranged at the bottom of the lower water tank on the pipe body 2 (12). The upper part of the lower water tank (15) is connected to the water pipe 1 (3), the other end of the water pipe 1 (3) is connected to the water pipe 2 (4) and the water pipe 3 (1) through the reversing valve (2), and the other end of the water pipe 3 (1) is connected to In the pool, water pipe 1 (3) and water pipe 2 (4) are also connected through water pipe 4 (5). The connection between water pipe 4 (5) and water pipe 1 (3) is higher than water pipe 4 (5) and water pipe 2 ( 4) to ensure that water does not flow from water pipe 2 (4) into water pipe 1 (3).

Valve 1 (8) is connected to valve 3 (11) through a connecting rod, and valve 3 (11) is controlled by a buoyancy device (14). When the water level of the lower water tank (15) is higher than position 1, valve 3 (11) remains closed , valve 1 (8) remains open; when the water level is below position 2, valve 3 (11) remains open and valve 1 (8) remains closed; when the water level is between position 2 and position 1, valve 1 ( 8) and valve 3 (11) are open at the same time.

Valve 2 (9) and valve 4 (13) are controlled by two switches respectively.

A water level display tube (16) is set outside the lower water tank (15) to display the water level in the water tank. The upper end of the water level display tube (16) is open, and an odor filter (17) is installed at the opening to filter the odor that may be produced by the secondary use of water. Lose.

The working principle of this water-saving and environmentally friendly water tank is: the water used in daily life enters the water pipe 3 (1) through the pool, and is diverted through the reversing valve (2) according to its usable value, and the water that can be reused enters the water pipe 1 (3 ), and those that cannot be reused enter the water pipe 2 (4) and drain directly. The water that enters water pipe 1 (3) can enter lower floor water tank (15). After the water of lower floor water tank (15) was full, even the water that entered water pipe 1 (3) also can be drained through water pipe 2 (4) by water pipe 4 (5) again.

Clean running water enters the upper water tank (10) through the running water pipe (6).

When the upper and lower water tanks are full of water, when in use, open the valve 4 (13) through the switch, and the water in the lower water tank (15) will flow out through the pipe body 2 (12) for flushing. When the water level drops to a certain position, The buoyancy device works, the valve 3 (11) is opened, and a part of the upper water tank (10) (the water level above the valve 1 (8)) clean tap water will enter the pipe body 1 (7), and then enter the pipe body 2 (12 ), so that after flushing, what is left in the toilet is still clean tap water, rather than reused and dirty water.

When the water level in the lower water tank (15) was not enough, the valve 2 (9) could be opened directly by the switch, and the water in the upper water tank (10) could be used to flush the toilet.

The water-saving and environment-friendly water tank provided by the invention realizes selective secondary utilization of domestic waste water, saves water resources, and is economical and practical.
